Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a shear wall reinforcement protective layer pad. Background Art

[0002] At present, 200mm long mortar pads or PVC circular clips are usually used as concrete protective layer pads for shear walls on residential floors. The use of mortar pads can control the thickness of the shear wall steel protective layer and the thickness of the shear wall to a certain extent, but many problems still exist during the construction process. During the installation process, the grooves at both ends of the pads are only 5-10mm deep, which cannot effectively lock the horizontal reinforcement. After installation, the cement pads are easily disturbed by human factors or break or fall due to the impact force of concrete during concrete pouring, thereby affecting the thickness of the steel protective layer. At the same time, the PVC circular clips are prone to tilting toward the inside of the wall when carpenters reinforce the wall formwork, and the thickness of the steel protective layer cannot be guaranteed. Therefore, a shear wall steel protective layer pad is proposed to solve the above problems. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shear wall steel bar protective layer pad, comprising a pad body, the pad body being a truncated cone structure with a small upper end and a large lower end; a locking groove is provided on the top of the pad body, and the bottom inside the locking groove is arc-shaped; anti-breakaway blocks are provided above both sides of the inside of the locking groove; a buffer hole adapted to the anti-breakaway block is provided on the inner wall of the locking groove, and one end of the anti-breakaway block is sleeved in the buffer hole, a spring is fixedly connected between the anti-breakaway block and the buffer hole, and the anti-breakaway block can move axially in the buffer hole.

[0005] In order to enhance the stability and bearing capacity of the structure, as a preferred shear wall steel bar protective layer pad of the utility model, a support pad is provided at the bottom of the pad body.

[0006] In order to improve the stability and safety of the entire concrete structure, a shear wall steel bar protective layer pad is preferably provided with a plurality of reinforcing ribs on the support pad, and the plurality of reinforcing ribs are evenly distributed along the outer circumference of the pad body.

[0007] In order to ensure that the pad body will not shift or fall off during the concrete pouring process, as a preferred shear wall steel bar protective layer pad of the utility model, both sides of the top of the pad body are provided with wire ties.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The utility model discloses that when the steel bar moves from the upper end of the locking groove to the inside, the anti-breakaway blocks on both sides are pushed to move axially in the buffer hole, which makes it easy for the steel bar to be placed in the locking groove. The anti-breakaway blocks are reset under the elastic force of the spring, which plays a limiting role on the top of the locking groove, can effectively lock the horizontal reinforcement and prevent the pad body from falling off; and the pad body is not easy to move, and can maintain a stable position in the steel skeleton, preventing the pad from deflecting or falling due to the impact force or vibration generated during concrete pouring, and ensuring the uniformity and consistency of the thickness of the steel bar protective layer;

[0011] Moreover, the supporting end of the pad body is larger than the installation end face, which can effectively enhance the strength and rigidity of the concrete structure, improve the overall bearing capacity and stability of the pad body, and prevent deformation or damage caused by stress concentration.

[0017] When the reinforcing bar moves from the upper end of the locking groove 2 to the inside, the anti-breakaway blocks 3 on both sides are pushed to move axially in the buffer hole 4, which makes it easy for the reinforcing bar to be placed in the locking groove 2. The anti-breakaway blocks 3 are reset under the elastic force of the spring 5, which restricts the top of the locking groove 2, and can effectively lock the horizontal reinforcement to prevent the pad body 1 from falling. At the same time, the anti-breakaway blocks 3 are attached to the reinforcing bar, which can limit the pad body 1 to the reinforcing bar, making the pad body 1 not easy to move, and can maintain a stable position in the reinforcing bar skeleton, preventing the pad from offsetting or falling due to the impact force or vibration generated during concrete pouring; and the supporting end of the pad body 1 is larger than the mounting end face, which can effectively enhance the strength and rigidity of the concrete structure, improve the overall bearing capacity and stability of the pad body 1, prevent deformation or damage caused by stress concentration, and easily provide stable support for the reinforcing bar, which helps to accurately fix the position of the reinforcing bar before concrete pouring, ensure that the reinforcing bar is arranged according to design requirements, thereby improving the overall quality of construction, reducing errors and uncertainties in the construction process, making the thickness of the concrete cover more uniform, and improving the overall performance of the structure.

[0018] As a technical optimization solution of the present invention, a support pad 6 is provided at the bottom of the cushion block body 1 .

[0019] In this embodiment: the support pad 6 increases the support area at the bottom of the pad body 1. The stable support helps to accurately fix the position of the steel bars before pouring concrete, ensuring that the steel bars are arranged according to the design requirements, thereby improving the overall quality of construction; and the pad body 1 forms a stable support structure between the steel bars and the concrete, which helps to disperse the pressure of the concrete on the steel bars, thereby enhancing the stability and bearing capacity of the structure.

[0020] As a technical optimization solution of the present invention, a plurality of reinforcing ribs 7 are provided on the support pad 6 , and the plurality of reinforcing ribs 7 are evenly distributed along the outer circumferential surface of the pad block body 1 .

[0024] As a technical optimization solution of the present invention, the pad body 1 and the support pad 6 are integrally formed, and the pad body 1 and the support pad 6 are made of hard polyvinyl chloride material.

[0025] In this embodiment: the rigid polyvinyl chloride material has durability and corrosion resistance;

[0026] The pad body 1 and the support pad 6 can maintain their stable performance for a long time in various harsh environments; this means that the pad can maintain its shape and size unchanged during long-term use, effectively supporting the steel bars and protecting them from the influence of the external environment; and the pad body 1 and the support pad 6 can effectively prevent the steel bars from being damaged by contact with corrosive substances (such as moisture, chemicals, etc.), which is crucial for extending the service life of the steel bars and maintaining the overall stability of the structure.

[0027] Working principle: First, when the steel bar moves from the upper end of the locking groove 2 to the inside, the anti-breakaway blocks 3 on both sides are pushed to move axially in the buffer hole 4, which makes it easy for the steel bar to be placed in the locking groove 2. The anti-breakaway blocks 3 are reset under the elastic force of the spring 5, which restricts the top of the locking groove 2, effectively locking the horizontal reinforcement and preventing the pad body 1 from falling; the pad body 1 is firmly fixed to the steel bar by tying the wire strip 8 to ensure that the pad will not shift or fall off during the concrete pouring process, and the thickness of the steel bar protective layer can be guaranteed to be uniform and consistent; the pad body 1 can be restricted on the steel bar, making it difficult for the pad body 1 to move and able to maintain stability in the steel bar skeleton The fixed position can prevent the pad from shifting or falling due to the impact force or vibration generated during concrete pouring, and the supporting end of the pad body 1 is larger than the installation end face, which can effectively enhance the strength and rigidity of the concrete structure, improve the overall bearing capacity and stability of the pad body 1, prevent deformation or damage caused by stress concentration, and easily support the steel bars stably, which helps to accurately fix the position of the steel bars before concrete pouring, ensure that the steel bars are arranged according to the design requirements, thereby improving the overall quality of construction, reducing errors and uncertainties in the construction process, making the thickness of the concrete cover more uniform and consistent, and improving the overall performance of the structure.
