Description

Technical Field

[0001] The invention relates to a basement outer wall anti-cracking and leakage structure. Background Art

[0002] Due to design, construction technology and construction organization reasons, the entire structure cannot be poured continuously and the interval time exceeds the allowed duration of concrete transportation and pouring. The joint surface of the concrete poured successively is called a construction joint. During the construction process, a waterstop is usually installed on the joint surface as a waterproof measure between the new and old concrete. At present, during the construction process, multiple holes are usually drilled on both sides of the waterstop and the waterstop is positioned with steel wire. Since the waterstop is pulled tightly and is in a tight state, the collision and friction between the stone and the waterstop during the vibration process can easily cause damage to the waterstop. If there are fewer holes for binding and positioning or the binding is not in place, it is easy to cause the waterstop to shift in position, affecting the waterproof effect and service life of the structure. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a basement exterior wall anti-cracking and leakage structure, in which the waterstop can be flexibly and reliably positioned by installing a clamping component and a limiting component, and can be loosened before the vibration process to prevent surface damage caused by excessive tension, and can be lifted and tightened by a hook after the vibration process.

[0005] As a further improvement of the present invention, the clamping assembly includes a clamping seat and several adjustment assemblies installed at both ends of the clamping seat. A cavity is provided in the middle of the clamping seat for the water stop belt to move up and down, and one side of the cavity is opened. The adjustment assembly includes a fixed rod, a double-headed screw and a connecting rod fixed on the clamping seat. The double-headed screw is installed between the fixed rod and the connecting rod for adjusting the extension distance.

The relatively abutting surfaces of the separately arranged clamping seat are respectively provided with a convex surface and a concave surface for positioning.

[0007] As a further improvement of the present invention, the limit assembly includes a limit seat, a limit block, and an ejection screw. The limit seat is provided with a sliding groove, the movable groove is opened toward the side of the clamping assembly, the limit block is installed in the sliding groove, and the ejection screw is installed at the end of the sliding groove away from the opening, for adjusting the ejection distance of the limit block.

[0018] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-4 As shown, a structure for preventing cracking and leakage of the outer wall of a basement includes a steel bar binding frame 1, transverse reinforcement ribs 2, longitudinal reinforcement ribs 3, and a waterstop 4. The waterstop 4 is installed in the middle of the steel bar binding frame 1, and the transverse reinforcement ribs 2 and the longitudinal reinforcement ribs 3 are arranged along the height direction of the steel bar binding frame 1 to enhance the strength of the overall frame. The waterstop 4 has a plurality of clamping components 5 arranged along its height direction at both ends relative to the steel bar binding frame 1. The clamping components 5 at both ends of the waterstop 4 are arranged relatively to each other and one end of the clamping component 5 abuts against the waterstop 4, and the other end is fixedly connected to the steel bar binding frame 1. The clamping components 5 installed at the top and the bottom are used to lock the waterstop 4. The clamping components 5 installed between the top and the bottom are used to lock the waterstop 4. Component 5 is used for positioning and guiding the waterstop 4, so that the waterstop 4 can be pulled on these clamping components 5 without clamping the waterstop 4. The longitudinal reinforcement rib 3 is fixedly connected with a limit component 6 to prevent the clamping component 5 from moving. When the exterior wall is vibrated after pouring, the waterstop 4 is in a slightly loose state. The clamping component 5 installed in the middle serves as a guide and positioning to prevent the waterstop 4 from shifting. After the vibration process is completed, the uppermost clamping component 5 is lifted and tightened by the hook. Since the middle clamping component 5 does not clamp the waterstop 4, the waterstop 4 is out of the loose state after being lifted and waits for the concrete to solidify.

[0020] The clamping assembly 5 includes a clamping seat 51 and several adjustment assemblies 52 installed at both ends of the clamping seat 51. The middle part of the clamping seat 51 is provided with a cavity 511 for the water stop belt 4 to move up and down, and one side of the cavity 511 is opened. The cavity 511 is adapted to the convex ribs and grooves on the water stop belt 4. The adjustment assembly 52 includes a fixed rod 521 fixed to the clamping seat 51, a double-headed screw 522, and a connecting rod 523. The double-headed screw 522 is installed between the fixed rod 521 and the connecting rod 523 for adjusting the extension distance. The end of the connecting rod 523 away from the fixed rod 521 is provided with a clamp 524 for clamping the steel bar binding frame 1, and a locking piece is provided at the opening of the clamp 524. The clamping seat 51 is separately set, and the separately set clamping seat 51 is clamped and installed from both ends of the water stop belt 4. The relatively abutting surfaces of the separately set clamping seat 51 are respectively provided with convex surfaces and concave surfaces for positioning. This arrangement facilitates the rapid installation of the clamping seat 51, and the installation is flexible and reliable. The clamping seat 51 and the clamping hoop 524 installed in the lowest clamping assembly 5 are in a clamped state to prevent the lowest clamping assembly 5 from being displaced due to pulling the uppermost clamping assembly 5. The clamping hoop 524 installed in the uppermost clamping assembly 5 retains the tightness when pulling to avoid the inability to lift the uppermost clamping assembly 5 due to the stuck hook. In order to facilitate the lifting of the hook, a clamping groove 525 is provided at the bottom of the limit seat 61 for easy cooperation with the hook.

[0021] The limit assembly 6 includes a limit seat 61, a limit block 62, and an ejector screw 63. The limit seat 61 is provided with a sliding groove, and the movable groove is opened toward the side of the clamping assembly 5. The limit block 62 is installed in the sliding groove, and the ejector screw 63 is installed at the end of the sliding groove away from the opening, which is used to adjust the ejection distance of the limit block 62. When installing, the limit assembly 6 is installed first, and the clamping assembly 5 is further installed according to the height of the limit assembly 6. The bottom of the limit seat 61 is provided with a U-shaped mouth 64 for clamping the longitudinal reinforcing rib 3, and a locking piece is provided at the opening of the U-shaped mouth 64. The U-shaped mouth 64 is provided. In order to facilitate the quick installation and fixation of the limit seat 61, the limit block 62 is provided with abutment plates 65 extending to both sides relative to the steel bar binding frame 1, and the end faces of the abutment plates 65 away from the clamping assembly 5 abut on the steel bar binding frame 1. The provision of the abutment plates 65 can further position the installation of the limit seat 61 and also help the limit seat 61 to adjust the installation angle. Slide blocks are provided on both sides of the limit block 62, and the sliding grooves are provided on both sides of the sliders corresponding to the sliding grooves for the sliders to move. The sliding grooves are open toward the side of the clamping assembly 5, and the sliders are provided to prevent the limit block 62 from escaping from the limit seat 61 in the height direction.

[0022] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
