Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a reinforcement device and method for a shear wall corner. Background Art

[0002] With the booming construction industry, the height of buildings is also increasing. The core tube structure is the main shear component of the building. As the height of the structure increases, the wall thickness is also increasing. However, since the tie screws in the wall column formwork are conventional standardized components, the corners of the structural wall that exceed the length of the tie screws cannot be effectively reinforced. The consequences may lead to quality problems such as mold expansion, slurry leakage, and irregular corners after the wall column is poured. If there are major problems with the reinforcement, there is even a risk of safety accidents. Based on this situation, the construction unit has also made several commonly used technical treatment solutions:

[0003] 1. For the shorter corners of the structural shear wall, the corner ends are reinforced by lengthening the tension screws.

[0004] Disadvantages: a. This process is mainly used for shorter shear walls. If the shear wall is too long, the tension screws will not be easy to penetrate and pull; b. It increases the welding workload and has high requirements for welding quality, otherwise the weld will be cracked or broken during the reinforcement process.

[0005] 2. At the corner, the end of the main purlin is reinforced by locking it to the main purlin on the other side with tension screws (adding a fixing device to the steel pipe).

[0006] Disadvantages: Since it is necessary to increase the stress points from the lateral main purlin, in order to prevent slipping, the stress points added in the vertical direction will be arranged after the first tension screw. If the shear wall is thicker, the length of the tension screw will be increased first (most processes use welding). Secondly, after reinforcement in this way, the shear wall is still stressed at both ends of the corner. If the wall is thicker, there will be a greater risk of mold expansion in the middle of the corner wall.

[0007] 3. Use inclined support to reinforce the bottom of the primary structure shear wall, use the anchor ring reserved on the floor slab as the stress point, and reinforce the side wall's reinforcement support system to the anchor ring.

[0008] Disadvantages: It has a better reinforcement effect on the lower part of the wall, but cannot effectively reinforce the higher part of the wall.

[0009] In summary, the corner part of the structural wall cannot be reinforced by penetrating tension screws because the corner wall is too thick and the shear wall is too long. As a result, the corner of the structural wall cannot be effectively reinforced. In the later stage, it may cause quality problems such as mold expansion, slurry leakage, and uneven corners after the wall column is poured, which poses a safety hazard. In addition, some commonly used treatment solutions still have various disadvantages. The external formwork reinforcement method cannot effectively reinforce thicker walls and may cause excessive lateral displacement of the wall. Summary of the invention

[0010] The present invention aims to provide a reinforcement device and method for the corner parts of shear walls, so as to solve the problem that the corner parts of the structural walls cannot be effectively reinforced due to the corner walls being too thick and the shear walls being too long, which may lead to quality problems such as mold expansion, slurry leakage, and irregular corners after the wall columns are poured in the later stage, posing a safety hazard.

[0011] The embodiment of the present invention is achieved as follows:

[0012] A reinforcing device for a shear wall corner, comprising a conversion component, wherein a blind hole is provided on the conversion component, one end of a tension screw is installed in the blind hole, and the other end extends out of the shear wall formwork;

[0013] A channel is provided inside the conversion component, and the channel runs through the conversion component. The axis of the blind hole is perpendicular to the axis of the channel. A sleeve is provided in the channel, and both ends of the sleeve extend out of the shear wall formworks on both sides respectively. A tension screw is provided in the sleeve.

[0014] When in use, first install one end of the tension screw in the blind hole of the conversion component. After the tension screw and the conversion component are installed in place, insert the casing and insert the tension screw in the casing. Therefore, the two tension screws will form a T-shaped structure. The two are connected by the conversion component. The conversion component is just located inside the corner of the shear wall, so that the corner can be effectively reinforced. There is no need to weld and extend the tension screw, which ensures the quality of the one-time structure casting, reliable structure, no safety hazards, and reduces the cost of later grinding and repair. In addition, the conversion component can be prefabricated in batches in the factory, and the on-site installation is simple and quick, which is convenient for workers to implement, and the molding effect is good after the casting is completed.

[0015] The reinforcement device for the corner part of the shear wall described in the present invention has a more significant effect on the corner part of the thicker shear wall, effectively reinforces the corner part, reduces costs, and is easy to implement.

In addition, the tension screw in the sleeve can be taken out and reused, which is economical.

[0046] The construction steps are simple, easy to operate, and the construction efficiency is high. The completed wall is stable and of high quality.

[0047] In one embodiment:
