Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and more specifically to a prefabricated building structure for multiple earthquake zones. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they employ standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods. Although prefabricated buildings have advantages such as short construction cycles and convenient disassembly, traditional prefabricated building structures are relatively simple, resulting in poor seismic resistance in actual use, especially in earthquake-prone areas where the seismic performance of prefabricated building structures needs to be carefully considered. To address this, the inventor proposes a prefabricated building structure for earthquake-prone areas.

[0003] To facilitate installation, accelerate construction, and reduce structural weight and seismic load, Chinese patent (authorization announcement number: CN203905289U) discloses a precast concrete frame-supported shear wall panel. This utility model precast concrete frame-supported shear wall panel consists of concealed columns, concealed beams, and a central rigid concrete wall panel. The central rigid concrete wall panel can be a rectangular solid or hollow wall panel. By controlling the boundary conditions of the wall, this wall panel can function as a frame support. This utility model only requires vertical connections at the concealed column locations, reducing the number of connection points and facilitating on-site installation. It also makes the structural stress more clearly defined. Because the central rigid concrete wall panel is designed for support, its thickness can be appropriately reduced or it can be made into a hollow wall, effectively reducing concrete usage, structural weight, and seismic load.

[0004] This solution still has some shortcomings in its application. Because the shear wall panels need to be kept perpendicular to the floor at a 90-degree angle during and after installation, they cannot be tilted, otherwise collapse is likely. Furthermore, concrete pouring is required to fix the shear wall panels to the ground, ensuring the pouring is firm and the shear wall panels are securely fixed. Therefore, improvements to the prefabricated building structure are needed to make it not only easy to install but also secure, perform well, and be suitable for use in earthquake-prone areas, ensuring safety. Utility Model Content

[0005] This utility model discloses a prefabricated building structure for multiple earthquake zones, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A prefabricated building structure for multiple earthquake zones includes a ground surface, prefabricated wall panels, composite beams, and composite slabs. The ground surface is provided with connecting steel bars and steel gaskets. The bottom of the prefabricated wall panels is provided with a first embedding groove and the lower part is provided with a casting groove with a casting port. The first embedding groove is adapted to be embedded with the steel gaskets, and the connecting steel bars are adapted to be embedded in the casting groove. The inner side of the prefabricated wall panels is equipped with an "L"-shaped vertical frame and a telescopic support rod. A load-bearing wall is provided between the prefabricated wall panels. The top of the load-bearing wall is provided with a second embedding groove with an upward opening. A beam support rod is provided between the second embedding grooves. The composite beam is embedded in the beam support rod, and the composite slab is covered on the composite beam.

[0008] Furthermore, the "L"-shaped vertical frame is equipped with a sensor that abuts against the precast wall panel. The retractable support rod is provided with a top seat and a base at its bottom and top, respectively. The top seat and the base are equipped with an upper hinge buckle and a lower hinge buckle, respectively. The upper hinge buckle is equipped with a suction cup that abuts against the precast wall panel.

[0009] Furthermore, the pouring inlets have six structures arranged in two parallel rows that are interconnected.

[0010] Furthermore, the load-bearing wall is cast using aluminum alloy formwork and is set perpendicular to the ground. The load-bearing wall is in the shape of an "I", "L" or "Z".

[0011] Furthermore, the composite beam and composite slab are provided with a first connecting steel bar at the top.

[0012] Furthermore, the precast wall panel is provided with second connecting steel bars on both sides, which are embedded in the aluminum alloy template and formed into one piece by concrete pouring.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0014] This utility model firstly uses precast wall panels with a first embedding groove and a casting groove. The casting groove has two rows of parallel and continuous casting ports. Simultaneously, connecting steel bars and steel shims are placed on the ground. The steel shims are fitted into the first embedding groove, and the connecting steel bars are embedded in the casting groove and fixed by grouting. After fixing, an "L"-shaped vertical frame and a telescopic support rod are used for support, ensuring the precast wall panels remain perpendicular to the ground at 90 degrees, preventing tilting and ensuring structural stability. The design is ingenious and highly practical. Next, load-bearing walls are constructed between the precast wall panels, and these load-bearing walls are cast using aluminum alloy tubular formwork. The precast wall panel and the load-bearing wall are integrated through a second connecting steel bar and concrete pouring, resulting in a robust structure that is less prone to cracking. Finally, a second embedding groove is first set at the top of the load-bearing wall, and the two ends of the composite beam are embedded and fixed within this groove. The composite panel is then placed on the composite beam, and the first connecting steel bar connects it to the surface steel bar, forming an integral structure before concrete pouring. This robust structure further enhances the stability of the prefabricated building structure. This utility model features a novel structure, ingenious design, good stability, and convenient assembly, making it suitable for widespread use in earthquake-prone areas. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

A beam support rod 13 is provided between the second embedding grooves 12. The composite beams 3 are embedded on the beam support rods 13, and the composite slabs 4 are covered on the composite beams 3.

[0025] Furthermore, the "L"-shaped vertical frame 9 is equipped with a sensor 91, which abuts against the precast wall panel 2. The retractable support rod 10 is equipped with a top seat 101 and a base 102 at its bottom and top, respectively. The top seat 101 and the base 102 are equipped with an upper hinge buckle 103 and a lower hinge buckle 104, respectively. The upper hinge buckle 103 is equipped with a suction cup 105, which abuts against the precast wall panel 2.

[0026] Furthermore, the pouring inlets 81 have six structures arranged in two parallel rows that are interconnected.

[0027] Furthermore, the load-bearing wall 11 is cast using aluminum alloy formwork and is set perpendicular to the ground 1. The load-bearing wall 11 is in the shape of an "I", an "L" and a "Z".

[0029] Furthermore, the precast wall panel 2 is provided with second connecting steel bars 15 on both sides. The second connecting steel bars 15 are embedded in the aluminum alloy template and formed into one piece by concrete pouring.

[0030] Example: First, a steel shim 6 is placed on the ground 1. The steel shim 6 has through holes at both ends, through which connecting steel strips 5 are inserted for fixation. Next, the precast wall panel 2 is vertically hoisted from above and abuts against the ground 1. The first embedding groove 7 is fitted into the steel shim 6, and the connecting steel strips 5 are embedded in the casting groove 8. The precast wall panel 2 is connected and fixed to the ground by an "L"-shaped vertical frame 9 and a telescopic support rod 10.

The suction cup 105 of the upper hinge buckle 103 of the telescopic support rod 10 abuts against and adheres to the precast wall panel 2, fixing it in place. Then… The two lower sections of the pouring port 81 are blocked, and grout is injected into one of them. The grout enters from top to bottom between the ground 1 and the precast wall panel 2 to permanently fix the two together. Next, aluminum alloy formwork is installed between the precast wall panels 2, and concrete is poured through the aluminum alloy formwork to form a load-bearing wall 11, making it an integral part of the precast wall panel 2. Then, the two ends of the composite beam 3 are placed into the second embedding groove 12 at the top of the load-bearing wall 11, and then the composite slab 4 is placed on top of the composite beam 3. Finally, the slab surface reinforcement 16 is set on the top of the composite slab 4 and the composite beam 3. The slab surface reinforcement 16 is connected and fixed to the first connecting reinforcement 14 to facilitate subsequent concrete pouring.
