1.1.3. Template installation

When installing the template at the initial installation, you can fix the 50mmx18mm wooden bar with a nail on the concrete surface until the inner side of the outer corner is used to ensure the module installation of the pairing line. All templates are installed from the corner, so that the template can keep the side stability.

Before installing the template, it is necessary to ensure that all template contact surfaces and edges have been cleaned and painted. When the corner is stable and the inner angle mold is positioned according to the positioning line positioning, the entire wall mold is installed. In order to dismantle convenience, the head of the sale should be in the inner angle mold as much as possible when the wall model is connected to the inner angle mold.

Before closing the template, you need to pre -jacket PVC pipes on the wall mold connector. At the same time, the contact position of the template surface of the tube and the two sides of the wall should be accurate in order to pour the concrete to retract the pull screw. When the exterior wall is deviated, it must be adjusted to the correct position as soon as possible. Just tilt the outer wall mold slightly in a plane. If there are two directions, the vertical deviation occurs, and the two layers should be adjusted to adjust one direction on one layer. Do not try to adjust the alignment of the template by unilateral promotion.

1.1.3.1. Installation of wall pillars

There are two ways to install the wall pillar template, namely “dual -mold” and “single model” installation. The peripheral wall and large area areas are usually installed in dual -mode method, and small -scale areas such as the middle wall are installed.

1) In the “dual -mode installation” method, the pair of templates are connected to the pull screw and sales of the pair, and the latter template is connected to the previous set with sales and wedges. Its advantages:

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

① No repetitive work;

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

② Two assembly workers can always communicate on both sides of the wall template to avoid blind operations.

2) The advantages of single -mode installation compared to dual -mode installation:

① Unilateral template closed synthetic square space. Adjusting the single -sided template when there is error is more convenient than adjusting the double -sided template.

② If the reinforcement is blocked, it can be seen because it can be seen, so it is easy to correct it without delaying the template installation.

③ When the template is closed, the floor mold installation can be started as soon as possible.

3) Pay special attention to the elevator well, because the treated treasury must be installed correctly on the flat -layer outer fence plate on the lower layer to ensure that the level of the outer fence of the flat mold is not affecting the verticality of the elevator well. However, the concrete where the template that is in line with it may be uneven. If the concrete is too high in some places, it may affect the calibration of the four sides of the elevator well, so it must eliminate the horizontal range beyond the allowable level. It is necessary to ensure that the concrete, especially the reinforcement, is not contaminated due to excessive or negligence. The wood bars are located on the concrete plate at the end of the wall and the door of the door. The wall template needs to be used to keep the line with a line and position it on the concrete floor to squeeze the bottom of its bottom. When performing these operations The verticality of the opening, if possible, the door hole is installed at the doorway.

Installation

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

Before installing the top edge of the wall and the beam corner mold, apply the mold at the contact surface of the component and the concrete.

When connecting the wall mold and the corner mold with the corner mold, insert the sales from the upper part to prevent the sales of the sale fall off during the pouring. After installing the top side of the wall, you can start installing the plate on the corner. You must ensure that the contact edge has been applied.

In most cases, board beams are used to support board molds. You can set up a diagram of the panel support beam in advance. Use 132mm sales and 350mm beam mold connectors to connect the DP in the board beam composition with the two adjacent plate support beams. Install the support rod in the direction of the beam on the pre -installed beam component. When removing the support rod, it can protect its bottom. Use the support rod to raise the beam to the appropriate position. By connecting the beam and the plate mold with the sales of the plates that have been installed in the corner. Ensure that the frame supports the beams before installation have been applied to the mold.

Each row of the first template has been connected to the top of the wall and the support beam. The second template only needs to be connected to the first board, (usually two sets of sales are enough).

The second template does not connect to the beam to place enough adjustment range when placing the third template in the same row. After connecting the third template and the second template, the second template is fixed on the beam. Place the remaining templates in the same way.

You can install many rows at the same time, and you can complete the oil on the ceiling mold before laying the reinforcement. After the installation of the top board is completed, the elevation of all the template surface should be checked. If you need to adjust, you can add the level of the cushion to the bottom of the support rod to adjust the horizontal degree.

Stairs template installation

All aluminum alloy templates are closed in the stairwell, and observation ports are left at the bottom to ensure that the overallness and size of the stairs are consistent.

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

The bottom mold is installed in the stairs. After the steel bar is passed, the mold seal is passed, and the inspection and reinforcement is checked before the concrete pouring. Concrete pouring should be carried out twice to avoid deformation of the template.

Install the flat mold peripheral sheet and detailed components

Where there are continuous vertical templates, such as elevator shafts, outer walls, etc., the floor is enclosed in a closed week with a flat -molded outer fence and is used as a connection component of the upper layer of vertical template.

After the next layer of pouring concrete, the last flat mold outer fence must be installed. One is used to fix the unpacking of the previous layer, and the other is surrounded by the floor of the floor with the upper part of the wall mold. After pouring concrete, the upper flat mold outer fence is retained as the starting point of the lower wall mold. Connecting the outer guard of the flat mold and the wall template: Make sure it is clean and oil before installing the flat mold. During the pouring period, in order to prevent sales from falling off, the sale must be inserted down from the frame of the wall mold to the upper frame of the flat mold. The flat mold outer fence is 26mmx16.5mm long pores. Before pouring, install the M18’s low -carbon steel bolts to the bottom of the groove. These bolts are anchored in the solidified concrete. After pouring, if you need to adjust the bolt to adjust the horizontal degree of the flat mold, it can also control the verticality of the template.

Attachment 14.

Positioning of the outer guard plate of the flat mold: Use the hanging wire to check the positioning of the flat mold peripheral sheet: the straight flat mold outer fenders can ensure the straight line of the next floor wall mold.

Align the outer fence method of the flat mold: Fix the vertical steel with a cross lever with a PVC sleeve, and then use it to install the workbench in the future. At the junction of the two flat -mode peripheral guards, B.K.S. (fixed on the upper part of the guard of the guard) to ensure that the connection is flat.

8) Clean up the remaining materials and other objects out of the pouring area.

9) Ensure that the supporting frame of the suspension working platform is reliable on the concrete structure.

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

Concrete pouring

The concrete pouring uses a fabric machine for construction above 8 floors.

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

The fabric machine is arranged on the lower floor structure floor, and measures such as steel cables are taken to fix them. The maximum weight of the fabric machine is 1400kg, the fabric machine has four feet support, so that the weight of each foot is 350kg, the aluminum template can withstand the maximum 6000kg per square meter, and the maximum support pressure of the single roots is 66420N. In this way, the aluminum template and single support can be sufficient to carry the weight and impact of the fabric machine, and the fabric machine is as close to the wall and the beam side during construction at the construction site.

The fabric machine pipelines and other planes are reserved.

After the concrete is poured, the weight is hung first, and then the weighing rod is turned on to the next task position. After the installation is installed, the weight is lifted and repeated the previous task.

Fix the fabric machine with a cable wind rope.

When the concrete is built, the segments are layered in sections. Each poured height should be determined according to the characteristics of the structural characteristics and the density of steel bars. Putting should be carried out continuously. If the interval must be intermittent, the interval time should be shortened as possible, and the secondary concrete should be poured before the concrete of the front layer.

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

The concrete pouring should be poured first, then the beam is then poured, and the plate is finally poured. Pour from the middle to both ends.

During the pouring process, observing template steel bars, reserved holes, embedded parts, tendons, etc. There are displays or blocking or blocking. The problems should be poured immediately and should be completed before the poured concrete. The height of the freedom of the setting of the concrete from the sling port must not exceed 2m. If it exceeds 2m, measures must be taken.

Maintenance work during concrete pouring

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

During the concrete pouring period, at least two operators must be on both sides of the wall to check the sales, wedges and the connection of the pull screws on both sides of the wall. Sales, wedges, or sliding to the pull thread will cause the shift of the template and damage to the template. The areas that are affected are required to be repaired after removing the template. Precautions during pouring:

1) Due to vibration, the sale/wedge shed.

2) Due to vibration, the beam/flat mold supports the decline in the adjacent area.

3) Ensure that the support of all special areas is intact, especially wall molds, column molds, beam molds and their support cannot be shifted.

4) Whether the concrete is overflowing at the window opening and other places.

Construction Notes

1) Forbidden to place templates facing down; prohibit flat templates from starting to stack; forbid the template as a slope, bridge board or pedal board;

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

2) After assembling the whole -face template, tighten the sales;

3) It is forbidden to hammer when installing the wedge;

4) Forbidden use of components that are not used properly without proper cleaning and oil painting;

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

5) Ensure that the installed suspension scaffolding is in the best state without damage;

6) Ensure that all decks and foot panels and handrails on the platform are installed;

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

7) The opening that is left on the floor for the template must be covered when the concrete is completed;

8) Any worker who works on the platform must be fastened and fixed on the reserved nails;

9) When pouring the positioning wooden bar from the floor after pouring, it should be ensured that no nails are exposed;

1.2. Template demolition process

Demolition template process

According to the progress requirements of this project, and in accordance with the DB11/694-2009 template early demolition technical regulations and the quality acceptance specifications of concrete construction, the templates are demolished in the order as shown below:

1) Demolition beam side mold, wall mold and column mold (non -load);

2) Demolition of the bottom mold (not disassembling);

3) Remove the bottom of the board (non -load);

4) Demolition beam bottom mold (support does not disassemble);

5) Remove the support of the beam bottom (non -load);

6) Remove the cantilever support of 2 meters.

Demolition wall template

After 12 hours of concrete pouring, the wall can be removed; the following parts have been removed before removing the wall mold:

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

1) All cushioning wood nailed to the concrete board;

2) Horizontal support;

3) Vertical steel ascent;

4) Sales and wedges on all templates have been demolished.

5) Pay special attention to safety issues when removing sales and wedges in external and hollow areas. In addition, during the demolition period, we must pay attention to collecting materials and recycle a large number of sales and wedges. When disassembling the mold, try to draw the work of pulling screws as much as possible. After removing the pull screw, the template can be removed.

6) Clean work immediately after all parts are removed. The sooner the clean, the better. When the template is fixed with the flat -mode outer fence, the wall mold is first demolished from the bottom. The first template on the row to be removed is difficult to remove because it is connected to other adjacent templates. If it is properly cleaned and applied before pouring, it is easy to remove template. If the remaining templates have been cleaned and painted before use, it will be easy to remove adjacent templates by using the special lever for demolition.

7) When the template is transferred to another place, make a logo and stack it reasonably in the appropriate place to prevent the upper and random phenomenon from installing the upper wall mold, and improve the speed of installation. When removing the exterior wall, pay special attention to the installation of the working platform.

Demolition of beams and board templates

Liang board template demolition strictly in accordance with the requirements of DB11/694-2009 “Mentor Early Delocation Technical Regulations”, when the test pressure of the same condition test block is not less than 10MPa, the bottom mold is removed. Do not disassemble and support the vertical spacing of not more than 1.2m. When dismantling the template for the first time, be careful not to disturb the support system; during winter construction, a comprehensive heat storage method should be adopted to ensure the strength of the concrete, and the mold can be dismantled after the intensity. Specifically as shown in the figure below:

After meeting the relevant demolition requirements, demolition.

The renderings of the beam board template after removal are as follows:

After the demolition requirements are reached, the bottom mold is forced, and the support spacing is 1200 × 1200

After the demolition requirements are reached, the bottom mold and side molds are performed without support. The bottom of the beam is 100 × 650 × (B+130), and B is the width of the beam section.

The support rod is locked with a fixed -slip lock to ensure the top support effect

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

Attachment 21. Beam board template demolition renderings

Before the demolition work, the work platform should be set up to ensure safety. When removing steel templates and all steel plate beams, at least two people work together. The first template of each column is supported on the top of the top of the wall

When on the mouth, first remove the neighboring template, then remove the sales and wedges from the template that needs to be removed, and use the module to separate the adjacent template. There are no board beams and templates that cross from one wall to another wall. First, remove the wall mold with the top of the wall with supporting lips. Sales and wedges that can only be dismantled with parts with demolition signs.

The floor template has a longer contact time than the wall mold and concrete. Unless there is proper cleaning and oil coating work before pouring, the top mold is not easy to get off. The demolished template should be cleaned immediately.

Dismantle support rod

When the floor intensity reaches the “Specifications for the Acceptance of Concrete Quality” GB50204, the support rod can be removed after the intensity requirement. The strength of the concrete when removing must meet the requirements of the table below:

When each supporting rod is removed, use a hand to grasp the support rod and use a wooden hammer to strike the lower part of the support rod in the direction of the support beam.

Clean, transport and stack template

Removing dirt

After all components are removed, remove the dirt with a spatula and steel wire immediately. The wire brush is only used for the cleaning of the template border. The longer the cleaning time, the more difficult it is to clean. Usually it is best to clean immediately in the place of demolition.

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

Transmission template

① The overall large template with a large weight and size pass through the stairs nearby.

② Transfer through hollow places.

③ Through the reserved hole on the top board, the concrete is sealed after transporting the template.

Stack

After the removal template is transported to the next installation point, stacked in a reasonable place in a reasonable order. Divide the door to reasonably stack the templates and make a clear logo, which is very helpful for the installation of the next layer of templates to avoid confusion during installation and cause unnecessary trouble.

Demolition of flat mold outer fence board

剪力墙结构高层住宅铝合金模板专项施工方案-铝合金模板施工工艺

Only remove the flat mold outer fence connected to the lower part of the wall template, and the upper flat mold outer fence is not removed and used to support the next floor wall mold. After the wall mold is removed, remove the anchor bolt, remove the lower layer of the outer fence plate, and then clean and apply oil to prepare for the next use. The anchor bolt should be cleaned with a steel brush after each use. Each layer of flat mold outer fence is used across layers.
