Description

Technical Field

[0001] This utility model relates to prefabricated stirrups that do not require cutting or reinforcement at the waterstop steel plate of the basement exterior wall. It is mainly applicable to the installation of stirrups at the waterstop steel plate of the horizontal construction joint of the cast-in-place basement exterior wall. It is especially applicable to the construction where the basement exterior wall intersects with the edge members of the shear wall or frame column, and the waterstop steel plate collides with the wall and column stirrups within the height range, making it impossible to lay the stirrups according to the design requirements. Background Technology

[0002] Waterproofing is typically achieved by installing water-stop steel plates at horizontal construction joints in basement exterior walls. However, when these pre-embedded water-stop steel plates encounter shear wall edge members or frame columns, they will intersect and collide with the wall and column stirrups within their height range, making it impossible to install them as required by the design. Traditional solutions and their problems are as follows:

[0003] (1) Drill holes in advance where the waterstop steel plate passes through the stirrups. The wall and column stirrups pass through the reserved holes. After the waterstop steel plate and stirrups are installed, weld the joint between the stirrups and the waterstop steel plate to seal it. Although this can ensure the stress performance of the stirrups, the waterstop steel plate is a thin plate. The arc welding has a large heating area and is prone to deformation, which can easily cause incomplete welding, arc sticking, sand holes, and burn through the waterstop steel plate, resulting in defects such as air permeability and water leakage, and loss of waterstop effect.

[0004] (2) First, install the waterstop steel plate. Cut the stirrups at the point where they pass through the waterstop steel plate and spot weld them to both sides of the waterstop steel plate. Alternatively, add a 5d long 90° hook to the cut end of the stirrups and then continuously weld them to the waterstop steel plate. In this method, the stirrups lose their seismic and shear resistance functions after being cut off, which affects their stress performance and structural safety. Spot welding with the waterstop steel plate does not serve to close the stirrups.

[0005] (3) No stirrups are provided in the area where the waterstop steel plate is installed in the wall and column. The area of ​​the missing stirrups is supplemented by an equal area in the adjacent area outside the waterstop steel plate. In this method, the stirrups in the area of ​​the waterstop steel plate in the basement exterior wall are located in the stirrup densification zone at the bottom of the column, which is the part of the column with the largest bending moment. Under strong earthquake action, it will become a plastic hinge zone. The densified stirrups at the column base play an important role in improving the shear bearing capacity of the member, strengthening the constraint on the concrete in the core area of ​​the section, and preventing the buckling of the longitudinal reinforcement under earthquake action. If no stirrups are provided in the area of ​​the waterstop steel plate in the wall and column, a vacuum will appear in the stirrups of the member within the height range of the waterstop steel plate, which will seriously affect the seismic and shear resistance of the member and cause safety hazards in important parts of the cast-in-place structure.

[0006] Therefore, there is an urgent need to invent a simple and effective prefabricated stirrup that does not require cutting or reinforcement at the water-stop steel plate of the basement exterior wall. Under the design concept of not cutting, reinforcing, or welding the stirrup, the water-stopping effect of the water-stop steel plate of the basement exterior wall is guaranteed, while improving the seismic and shear resistance of the wall and column, and ensuring the safety of the structure. Summary of the Invention

[0007] The purpose of this utility model is to address the issue of prefabricated stirrup structures used at the waterstop steel plate of the basement exterior wall when it intersects with the edge components of the shear wall or frame columns. These structures involve pre-welding the upper elliptical stirrup, lower elliptical stirrup, and vertical stirrup into a single unit, then assembling and connecting single-leg mountain-shaped reinforcing bars via sleeves. The waterstop steel plate is inserted into the cavity formed by the upper elliptical stirrup, lower elliptical stirrup, and vertical stirrup. The waterstop steel plate is clamped and fixed on both sides using disc-shaped steel clamps. This design not only satisfies the waterstop effect of the basement exterior wall waterstop steel plate but also improves the seismic and shear resistance of the wall and columns, ensuring structural safety and achieving the function of not cutting, reinforcing, or welding the stirrups.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: Prefabricated stirrups for the basement exterior wall waterstop steel plate, requiring no cutting or reinforcement, including an upper elliptical stirrup, a lower elliptical stirrup, vertical stirrups, sleeves, telescopic adjustment rods, disc-shaped steel clamps, single-limb mountain-shaped reinforcements, and a waterstop steel plate. Multiple vertical stirrups are arranged between the upper and lower elliptical stirrups. Sleeves are provided on the outer side of each vertical stirrup, and the single-limb mountain-shaped reinforcements are connected to the vertical stirrups through the sleeves. A telescopic adjustment rod is provided on the inner side of each vertical stirrup, and the disc-shaped steel clamp is fixed to the end of the telescopic adjustment rod. The upper elliptical stirrup, lower elliptical stirrup, vertical stirrups, and single-limb mountain-shaped reinforcements together constitute the prefabricated stirrups. The waterstop steel plate is inserted into the cavity formed by the upper elliptical stirrup, lower elliptical stirrup, and vertical stirrups. The disc-shaped steel clamps are located on both sides of the waterstop steel plate, and the disc-shaped steel clamps on both sides of the waterstop steel plate are tightly attached to the waterstop steel plate.

[0009] Preferably, the upper elliptical hoop, the lower elliptical hoop, and the vertical hoop are welded together to form an integral structure.

[0010] Preferably, the sleeve has a threaded structure inside.

[0011] Preferably, the wall column reinforcement also includes vertical reinforcing bars that pass through prefabricated stirrups and are connected to single-leg mountain-shaped reinforcing bars by binding wire.

[0012] Preferably, the water-stop steel plate is installed along the entire length of the basement exterior wall, and the water-stop steel plate passes through multiple sets of prefabricated stirrups.

[0013] This utility model has the following features and beneficial effects:

[0014] (1) The stirrups at the water-stop steel plate of the basement exterior wall of this utility model adopt the prefabricated stirrup structure, which can effectively avoid the collision problem of the steel bars at the intersection of the basement exterior wall and the edge components of the shear wall or the frame column. The water-stop steel plate does not need to reserve stirrup holes, thus ensuring the water-stopping effect.

[0015] (2) The prefabricated stirrup structure of this utility model does not require cutting and welding at the water-stop steel plate, which ensures the integrity and continuity of the stirrup, plays the role of closing the stirrup, and ensures the stress performance and structural safety.

[0016] (3) The single-limb mountain-shaped reinforcement of this utility model is connected to the vertical hoop through the sleeve. The upper elliptical hoop, the lower elliptical hoop, and the vertical hoop can be pre-welded into an integral structure and installed before the single-limb mountain-shaped reinforcement is installed. It is not limited by the space of the vertical reinforcement of the wall column, the arrangement is flexible, the installation is convenient and quick, and the cost is low.

[0017] (4) This utility model installs a telescopic adjustment rod and a disc-shaped steel clamp on the upright hoop. The position of the disc-shaped steel clamp is adjusted by the telescopic adjustment rod, and the water-stop steel plate is clamped by the disc-shaped steel clamp. The water-stop steel plate is firmly installed and has a good waterproof effect. Attached Figure Description
