Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated floor slab installation, and in particular relates to a prefabricated floor slab anchoring structure. Background Art

[0002] During the installation of prefabricated floor slabs, although prefabrication technology has greatly improved construction efficiency and building quality, the existing anchoring structure still faces a series of technical defects that cannot be ignored. These defects may not only affect the construction progress, but also endanger the overall stability and safety of the building structure.

[0003] First of all, the rationality of the anchor design is the key to ensure the stable installation of prefabricated floor slabs. However, in actual applications, some anchor designs fail to fully consider the interaction between the floor slab and the supporting structure, resulting in the specifications, quantity and arrangement of the anchor steel bars or connectors being difficult to meet the actual force requirements. This design deficiency directly affects the bearing capacity and stability of the anchor structure, and increases the risk of the floor slab loosening, slipping or even falling off during use.

[0004] Secondly, the manufacturing accuracy of prefabricated floor slabs is also an important factor affecting the installation quality of anchoring structures. Due to the influence of factors such as production process, equipment accuracy and human operation, prefabricated floor slabs may have problems such as dimensional deviation and insufficient flatness during the manufacturing process. These problems will be further magnified during the installation of the anchoring structure, making it difficult to accurately align the anchoring position, increasing the difficulty and error of installation. At the same time, the omission or deviation of embedded parts (such as lifting rings, connectors, etc.) is also a common problem in the manufacturing process, which will directly affect the integrity and effectiveness of the anchoring structure. Summary of the invention

[0005] The purpose of the present invention is to propose a prefabricated floor slab anchoring structure in order to solve the problems that the bearing capacity and stability of the floor slabs installed in the existing prefabricated floor slab installation process are poor, and embedded parts are easily missed, resulting in poor stability and safety of the building structure.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a prefabricated floor slab anchoring structure, comprising a floor slab, wherein a reserved hole is arranged on the floor slab, and an anchor comprises a first connecting member, a second connecting member and a screw rod, wherein the first connecting member is connected to the top of the screw rod, and the bottom of the screw rod passes through the floor slab and is connected to the second connecting member.

[0007] As a further description of the above technical solution:

[0008] The first connecting member is provided with a connecting head, and the connecting head is connected to the suspension rod.

[0009] As a further description of the above technical solution:

[0010] The first connecting member comprises an abutment body and a threaded sleeve, the threaded sleeve is connected to the abutment body, and the top of the screw rod is connected to the threaded sleeve.

[0011] As a further description of the above technical solution:

[0012] The abutting body is in the shape of a gear.

[0013] As a further description of the above technical solution:

[0014] A reinforcement body is arranged between the first connecting member and the floor slab, and the reinforcement body is sleeved on the screw rod.

[0015] As a further description of the above technical solution:

[0016] The cross section of the reinforcement body is a trapezoid that is narrow at the top and wide at the bottom.

[0017] As a further description of the above technical solution:

[0018] A limiting groove is arranged above the reserved hole, and the limiting groove matches the bottom of the reinforcement body.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In the present invention, by utilizing the cooperation between the first connecting member, the second connecting member and the screw rod, when the floor slab needs to be installed, the top of the screw rod passes through the base plate and is connected to the hanger, and the gear-shaped first connecting member is directly embedded in the base plate, and the bottom passes through the floor slab and is screwed to the second connecting member. A screw sleeve is provided at the bottom of the first connecting member, which can abut the base plate and limit the reinforcement body. This structure utilizes the interaction of various components to greatly improve the stability of the installation, while ensuring that no loosening occurs during the installation process.

[0021] 2. In the present invention, the reinforcement body adopts a trapezoidal shape that is narrow at the top and wide at the bottom, and is sleeved on the screw rod, which not only improves the bearing capacity and stability of the floor slab, but also greatly increases its safety.

[0022] 3. In the present invention, by setting a first connecting member, the first connecting member is equipped with a connecting head. When installing, it only needs to be passed through the reserved hole on the floor slab to install it. There is no need to worry about missing the embedded parts, and a limiting groove is set on the top of the reserved hole. While limiting the screw, the outer surface of the reserved hole is also protected to avoid damage to the reserved hole. BRIEF DESCRIPTION OF THE DRAWINGS
