Description

Construction method of building external wall scaffolding connecting wall parts

technical field

The invention relates to a construction method of a building outer wall scaffolding connecting wall piece.

Background technique

With the development of infrastructure construction, there are more and more high-rise buildings. Since most high-rise buildings use frame shear wall structure, the scaffolding and connecting wall parts of the building exterior wall cannot be uniform in accordance with the specification due to the existence of the external shear wall. Equidistant arrangement, the construction of scaffolding poses a safety hazard. In the construction project, the connecting wall is a component used to connect the scaffold body with the main structure of the building and can transmit tension and pressure. The connecting wall is used to realize the attachment of the scaffolding, which can strengthen the overall stability of the scaffold and improve its stability. Bearing capacity and avoidance of major accidents such as tipping or collapse play an important role. In addition, the traditional wall joints must be left with scaffolding during the masonry, and the later blocking will easily cause the wall to leak, so it is urgent to solve this problem.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a construction method of scaffolding and wall-connecting parts for building exterior walls. This method ensures that the scaffolding-connecting wall parts can be arranged evenly and equidistantly according to the specification, avoids the potential safety hazards of scaffolding construction, and solves the problem of The problem of water leakage on the wall caused by hand-eye blocking improves the construction quality.

In order to solve the above-mentioned technical problems, the construction method of the building outer wall scaffolding connecting wall piece of the present invention comprises the following steps:

Step 1: According to the design drawings of the building exterior wall scaffolding, determine the position where the building exterior wall formwork needs to embed the connecting wall piece, and open a hole matching the diameter of the thread embedded section of the connecting wall piece at this position;

Step 2. After the reinforcement of the beams and slabs of the building exterior wall is completed, screw the pre-embedded section of the connecting wall into the bolt fastener and insert the hole into the beam member at the edge of the building exterior wall, and the pre-embedded section passes through the bolt fastener. It is fixed on the formwork, and the embedded section is fixed with wire ties and steel bars;

Step 3. Concrete is poured on the outer wall of the building to prevent the pre-embedded section from falling off and shifting during pouring;

Step 4. When the concrete is maintained until the side formwork of the exterior wall of the building can be removed, the bolt fasteners are removed, and then the side formwork is removed, the external steel pipe is connected to the embedded section of the connecting wall through the thread, and the external steel pipe is connected to the external wall of the building. The anchored end of the scaffolding.

Because the construction method of the building exterior wall scaffolding connecting wall piece of the present invention adopts the above technical scheme, that is, the method first determines the position where the building exterior wall formwork needs to be pre-embedded with the connecting wall piece, and at this position, the thread pre-embedded with the connecting wall piece is opened. The hole with the matching diameter of the section; after the reinforcement of the beams and slabs of the building exterior wall is bound, screw the embedded section into the bolt fasteners and insert the hole into the beam member at the edge of the building exterior wall. On the formwork, and fix the embedded section; pour concrete on the exterior wall of the building, and prevent the embedded section from falling off and shifting; when the concrete is maintained until the side formwork of the exterior wall of the building can be removed, remove the bolt fasteners, and then remove the side formwork. The external steel pipe is connected to the embedded section through the thread, and the external steel pipe is connected to the anchoring end of the outer wall scaffolding of the building. The method ensures that the scaffolding and wall parts can be arranged evenly and equidistantly according to the specification, avoids the hidden safety hazards of scaffolding construction, solves the problem of water leakage on the wall surface caused by the blocking of the scaffolding and eyes, and improves the construction quality.

Detailed ways

Embodiment As shown in Fig. 1 and Fig. 2, the construction method of building exterior wall scaffold connecting wall piece of the present invention comprises the following steps:

Step 1, determine the position where the building exterior wall formwork 2 needs to embed the wall fittings according to the design drawings of the scaffolding of the building exterior wall 1, and open a hole matching the diameter of the thread embedded section 3 of the connecting wall fittings at this position;

Step 2. After the building exterior wall 1 beams and slabs are bound with steel bars, the embedded section 3 of the connecting wall is screwed into the bolt fasteners 4 and then inserted into the hole into the building exterior wall edge beam member, and the embedded section 3 passes through. The bolt fastener 4 is fixed on the formwork 1, and the embedded section 3 is fixed with the wire 5 and the steel bar;

Step 3. Concrete is poured on the outer wall 1 of the building to prevent the pre-embedded section 3 from falling off and shifting during pouring;

Step 4. When the concrete is maintained until the side formwork of the building exterior wall 1 can be removed, the bolt fasteners 4 are removed, and then the side formwork is removed, and the external steel pipe 6 is connected to the embedded section 3 of the connecting wall piece by thread, and the external steel pipe 6 Connecting the anchoring end of the scaffolding on the exterior wall of the building.

The method can make the connecting wall parts evenly embedded in the main structure of the building, and solve the problem that the external shear walls and other components of the building affect and hinder the equidistant and evenly pre-buried scaffolding connecting wall parts; Leaving the scaffolding eyes solves the problem of water leakage on the wall caused by the blocking of the scaffolding and eyes, and overcomes the problems caused by the traditional scaffolding connected to the wall.

The method of pre-embedding the connecting wall parts is simple and easy to dismantle, eliminating the tedious steps of later dismantling the outer frame of the scaffold and cutting the steel pipes of the connecting wall parts, and is not affected by the shear wall and other components. It avoids the trouble that the traditional connecting wall piece affects the carpenter to set up a high-level inner frame, and solves the problem that the carpenter always removes the connecting wall piece for setting up the inner frame and does not restore it at the construction site, thereby improving the construction quality.
