Description

Technical Field

[0001] The utility model relates to the technical field of basement outer wall tie node reinforcement structure, in particular to a basement outer wall tie node reinforcement structure. Background Art

[0002] In the existing technology, the construction of basement exterior walls usually uses ground-based scaffolding as the supporting structure. The stability and safety of these scaffolding are key considerations during the construction process. Traditionally, for ground-based scaffolding located on the basement exterior wall, the general practice is to use a guy brace as the external frame anchor point. When the lower part of the scaffolding cannot be connected to the wall temporarily, anti-overturning measures should be taken. When setting up guy braces, they should be full-length rods and fixed to the scaffolding with rotating fasteners. The inclination angle with the ground should be between 45° and 60°.

[0003] The guy support should be removed after the external frame is removed. Since the inclined rod is usually stuck on the slope of the shotcrete anchor and a steel pipe is installed into the soil, it will destroy the overall stability of the slope over time and easily cause the slope to become unstable. In addition, the setting and construction of the guy support are difficult, and there are safety risks during the setting process of the external frame workers.

[0004] Too long a guy brace will generate a downward pulling force in the direction of the guy brace, which not only threatens the stability of the scaffolding, but may also cause additional burden on the basement exterior wall;

[0005] The practice of pre-buried steel pipes in exterior walls can easily lead to leakage in the exterior walls, as the seal between the steel pipes and the concrete is difficult to maintain for a long time;

[0006] The existing tie-in method is difficult to adapt to different spacings between the frame and the sidewall of the foundation pit, which limits its application in different construction environments.

[0007] How to solve the above problems is the research topic of this program. Utility Model Content

[0056] When the utility model is used, the following steps are included:

[0057] During the reinforcement binding process of the basement outer wall, water-stop screws 3 with water-stop gaskets 8 are pre-embedded, and two water-stop screws 3 are set up one above the other;

[0058] Remove the side formwork after concrete pouring;

[0059] A sleeve 4 is provided on the outer wall of the water-stop screw 3, and pads 5 are provided at both ends of the sleeve 4. The pad 5 at one end of the sleeve 4 abuts against the side wall of the basement outer wall, and the pad 5 at the other end of the sleeve 4 is fastened by a nut 6, so that the sleeve 4 and the basement outer wall are fully pressed against each other;

[0060] One end of the upper and lower sleeves 4 is fixedly connected to the vertical rod of the scaffold 2 through the U-shaped hoop plate 9;

[0063] During the dismantling process of the scaffold 2, the sleeve 4 is cut off and the cutting point is handled in the same way as the water stop screw.

[0064] First, you need to use appropriate tools such as a cutting machine to cut the exposed waterstop screws from the wall. The cutting depth should ensure that the end of the screw enters the wall to a certain depth, usually not less than 20mm, to ensure the waterproof effect.

[0065] After cutting, the cutting point needs to be cleaned to remove the remaining concrete debris and loose rust on the screw surface.

[0066] Apply anti-rust paint to the screw head to prevent rust

[0067] Use appropriate waterproof materials such as polymer cement mortar to seal the holes left after the screw is cut off, ensure that the seal is dense, and enhance the waterproof performance of the wall.

[0068] After sealing is completed, it may be necessary to construct a waterproof layer at this location, such as applying polyurethane waterproof coating, to provide additional waterproof protection.

[0069] For grooves or uneven areas caused by cutting off the screws, you can use appropriate materials to repair them and restore the flatness of the wall.

[0070] Through the above steps, it can be ensured that the waterproof performance of the wall will not be affected after the water-stop screw is removed, while also ensuring the beauty and structural integrity of the wall.
