Problems solved by technology

The disadvantages of using pre-embedded inner wires include: 1. It is easy to enter foreign matter, concrete, etc., and foreign matter enters, resulting in loose reinforcement and damaged mold expansion; 2. If the inner wire is inclined during pre-embedding, it is difficult to screw into the screw rod due to angle problems during installation.
The problems of using through holes are: 1. It needs to be sealed in the later stage, and if the sealing is not strict, it is easy for water to enter; 2. It is impossible to add a decorative surface

Embodiment 1

[0063] Such as Figure 1-4 As shown, in this embodiment, the side with the inner leaf wall 102a is the shear wall 102, that is, it completely includes the inner leaf wall 102a, the outer leaf wall 102c and the insulation board 102b. The wall connected to the shear wall 102 is a pcf board 103, which only includes the outer leaf wall 103c and the insulation layer 103b, and the inner leaf wall 103a is obtained by cast-in-place. An L-shaped corner cast-in-place area is formed between the walls.

[0064] The raised formwork 2 closes the cast-in-place area 101 . The template 2 is made of metal, and the inner wire mother 301 is located in the inner leaf wall 103a. Since it is an L angle, the template is also L-shaped. There is a rib structure on the outer side of the formwork 2, and the rib structure includes a plurality of parallel and horizontally arranged transverse ribs 51, and longitudinally arranged longitudinal ribs 52 located on the transverse ribs. In this embodiment, th...

Embodiment 2

[0071] Such as Figure 6-11 As shown, in this embodiment, the side with the inner leaf wall 102a is a shear wall, that is, it completely includes the inner leaf wall 102a, the outer leaf wall 102c and the insulation board 102b. The wall connected to the shear wall is a pcf board, which only includes the outer leaf wall 103c and the insulation layer 103b, and the inner leaf wall has not yet been cast-in-situ. An L-shaped corner cast-in-place area is formed between the walls.

[0072] Template 2 can be made of wood or other materials. On the back of the formwork 2 there are cylindrical or other similarly shaped transverse ribs 51 arranged in multiple groups in parallel, and the inner side of the transverse ribs 51 is a longitudinal rib 52, and in this embodiment the longitudinal ribs 52 are multiple wooden squares arranged vertically.

[0073] The first reinforcement tool includes two types in this embodiment. The first type is used to reinforce the formwork, insulation layer,...

Embodiment 3

[0080] Such as Figure 12-13 As shown, this embodiment is basically the same as Embodiment 2, the difference is that the inner leaf wall 103a inside the pcf board has been formed, and the first reinforcement tool 3 used in the inner leaf wall is the first reinforcement tool of the second type in Embodiment 2 , the second reinforcing tool 4 is also arranged in a cross shape like the first embodiment.

[0081] A construction method for formwork reinforcement in a wall cast-in-place area, comprising:

[0082] Step 1: Butt two adjacent walls, support the formwork, and form the cast-in-place area of ​​the wall structure;

[0083] Step 2: Connect the formwork and the wall structure through the first reinforcement tooling; the first reinforcement tooling includes an inner wire nut and a fast wire assembly, the inner wire nut is located in the wall structure, and the fast wire assembly Connect with one end of the inner wire nut close to the formwork, so as to realize the fixing of t...

Abstract

The embodiment of the invention provides a wall cast-in-place area formwork reinforcing structure. The wall cast-in-place area formwork reinforcing structure comprises a wall structure comprising a cast-in-place area; a formwork connected with the wall body structure so as to seal the vertical face of the cast-in-place area; a first reinforcing tool for reinforcing connection between the formworkand the wall structure, wherein the first reinforcing tool comprises an inner nut and a fast wire component, the inner nut is located in the wall structure, which is an embedded inner wall nut (MK1) when located on an inner leaf wall, and is an embedded outer leaf plate nut (MK2) when located on an outer leaf plate; the fast wire component is connected with the end, close to the formwork, of the inner nut so as to realize the fixation of the formwork and the wall structure; the inner nut is internally provided with a hollow structure, and a protrusion is arranged on the inner side of at leastone end of the hollow structure and used for being connected with the fast wire component. The embodiment of the invention further provides a construction method for reinforcing the wall cast-in-placearea formwork.

Description

technical field [0001] The invention relates to a formwork reinforcement technology for wall construction, in particular to a formwork reinforcement structure and a construction method in a pouring area of ​​a wall. Background technique [0002] During the assembly and construction of the prefabricated wall, it is necessary to butt the two walls. After the two walls are butted, there is still a certain interval between them. This interval is the cast-in-place area of ​​the wall. The façade of the cast-in-place area is usually open, and it is necessary to support the formwork, fix the formwork with the prefabricated walls on both sides, close the cast-in-place area, and then pour concrete from the top into the cast-in-place area, so as to realize the adjacent Connection of prefabricated walls. [0003] Currently, there are mainly two ways to fix the template. One is to pre-embed the inner wire in the inner wall of the prefabricated wall as a fixed connection structure with ...
