Description

Technical Field

[0001] This utility model relates to a concrete structure, and more particularly to a precast concrete structure, belonging to the field of precast concrete technology. Background Technology

[0002] Precast concrete refers to concrete products made in a factory or on-site. Precast concrete is poured elsewhere rather than at the final construction site, and fiber reinforcement can be used to enhance its reliability and toughness after cracking in different sizes and shapes of precast concrete.

[0003] In the existing technology of concrete building construction, the common method is to install precast concrete wall panels with steel bars and anchor bolts. However, during the installation process, collapse or deformation may occur at the connection between the two concrete structures. Since concrete is usually prepared on-site to fill the gaps and exposed steel bars at the connection, the precast concrete wall panels are heavier and downward, which can cause the filling concrete to deform before it solidifies under the action of gravity. In addition, the precast concrete wall panels are not strong enough because they are only fixed by steel bars and anchor bolts. Utility Model Content

[0004] The main purpose of this utility model is to solve the problem that the concrete filling the joints during assembly will deform and collapse before it solidifies, resulting in insufficient strength, and to provide a prefabricated concrete structure.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A prefabricated concrete structure includes a base slab and a concrete wall panel installed on the base slab. Connecting grooves are provided on all four sides of the concrete wall panel. Multiple transverse and longitudinal reinforcing bars are interlaced inside the concrete wall panel. Corner assembly plates are provided at the four corners of the front side of the concrete wall panel, and connecting plates are provided on all four sides of the front side of the concrete wall panel.

[0007] Furthermore, a reinforcing plate is installed in the middle of the concrete wall panel.

[0008] Furthermore, connecting plates are slidably connected to both ends of the reinforcing plate.

[0009] Furthermore, both the connecting plate and the reinforcing plate are provided with threaded holes.

[0010] Furthermore, an expansion bolt inserted into the concrete wall panel is welded to one side of the reinforcing plate.

[0011] Furthermore, two positioning bosses are provided at the center of each of the four sides of the concrete wall panel.

[0012] Furthermore, the concrete wall panel and the base plate are assembled using stirrups.

[0013] Furthermore, both the connecting plate and the corner assembly plate are installed on the outer wall of the concrete wall panel using fixing bolts.

[0014] Furthermore, a mounting plate is provided on one outward end of the connecting plate, and mounting plates are provided on both outward end faces of the corner assembly plate.

[0015] Furthermore, each of the mounting plates is provided with mounting holes.

[0016] The beneficial technical effects of this utility model are as follows: According to the prefabricated concrete structure of this utility model, the connecting grooves on the four sides of the concrete wall panel are used for concrete filling during assembly. During installation, the positioning bosses can provide support to prevent collapse or deformation of the filled concrete before it has set. At the same time, the connecting plate can further improve the vertical stability. The longitudinal and transverse steel bars exposed in the connecting grooves on the left and right sides of the concrete wall panel can be reinforced with stirrups when assembling two concrete wall panels. Then, the filling concrete can further improve the stability. The reinforcing plate can improve the strength and, together with the connecting plate, further improve the stability. Moreover, the gap can be adjusted according to the needs by using the threaded holes on the connecting plate to improve the adaptability. Attached Figure Description
