Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a connection structure for prefabricated wall panels in prefabricated buildings. Background Technology

[0002] Prefabricated construction, as an important direction for the development of modern building industrialization, has the core advantage of improving construction efficiency, simplifying processes, and reducing environmental impact through the prefabrication and on-site assembly of standardized components. Prefabricated wall panels, as key load-bearing components, must be firmly connected to longitudinal steel reinforcement frames and horizontal structures on the construction site to ensure the stability and load-bearing capacity of the overall structure.

[0003] Currently, in actual construction, precast wall panels are mostly connected by manually tying and fixing the embedded steel bars and vertical steel reinforcement frames with wire. This connection method has the following shortcomings: First, the structural stability after wire tying is poor, especially under the action of large loads or external forces such as earthquakes, which can easily lead to loosening or misalignment. In addition, the traditional tying method makes it difficult to adjust the connection structure when the installation height is inconsistent or the position of the steel bars deviates significantly, resulting in insufficient construction flexibility. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a prefabricated wall panel connection structure for prefabricated buildings, which has strong connection reliability and wider applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated wall panel connection structure for prefabricated buildings includes a vertical beam steel frame and a cross-shaped connector. The cross-shaped connector includes a vertical half-meniscus and a horizontal half-meniscus, which are fixed by welding. The included angle between the vertical half-meniscus and the horizontal half-meniscus is 90°. Binding openings are provided inside the vertical half-meniscus and the horizontal half-meniscus.

[0007] Furthermore, the vertical meniscus is fastened to one side of the vertical beam reinforcement frame, and the vertical meniscus and the vertical beam reinforcement frame are fixed together by binding wire.

[0008] Furthermore, precast wall panel bodies are symmetrically arranged on both sides of the vertical beam steel reinforcement frame, and a wall panel steel reinforcement skeleton is arranged inside the precast wall panel body, with the ends of the wall panel steel reinforcement skeleton protruding outside the precast wall panel body.

[0009] Furthermore, the horizontal semi-circular plate is fastened to one side of the wall panel reinforcement skeleton, and the horizontal semi-circular plate and the wall panel reinforcement skeleton are fixed by binding wire. The cross-shaped butt buckle is used to connect the precast wall panel body and the vertical beam reinforcement skeleton.

[0010] Furthermore, a reinforcing steel hoop is nested on the outer side of the vertical beam reinforcing steel frame, and the reinforcing steel hoop and the vertical beam reinforcing steel frame are bound together and fixed with tie wire.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting up a cross-shaped connection between the vertical and horizontal semi-circular plates, a stable cross-connection structure can be formed between the steel reinforcement skeleton of the precast wall panel body and the steel reinforcement frame of the vertical beam. Compared with the traditional method of using wire ties for single-point binding, the cross-shaped connection provides rigid support in multiple directions, significantly improving the stability of the connection and the load-bearing capacity of the overall structure, and solving the problems of loose connection, uneven stress and easy misalignment in the existing technology.

[0013] By setting binding holes inside the vertical and horizontal menisci and using a wire fixing structure to achieve rapid installation, the complexity of operation for construction workers when working at heights can be effectively reduced, assembly efficiency and construction safety can be improved, and the technical problems of low construction efficiency and complicated process under traditional connection methods can be overcome.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-5 As shown, a prefabricated wall panel connection structure for prefabricated buildings includes a vertical beam steel frame 101 and a cross-shaped butt joint 103. The cross-shaped butt joint 103 includes a vertical meniscus 131 and a horizontal meniscus 132. The vertical meniscus 131 and the horizontal meniscus 132 are fixed by welding. The included angle between the vertical meniscus 131 and the horizontal meniscus 132 is 90°. The ends of the vertical meniscus 131 and the horizontal meniscus 132 are aligned to form a compact and regularly shaped cross connection unit. Binding openings 133 are evenly provided inside the vertical meniscus 131 and the horizontal meniscus 132. The binding openings 133 are elliptical through-structures, which facilitate the insertion of binding wires and their firm binding with the steel reinforcement components. This structure solves the problems of unstable, large deviation, and low construction efficiency of traditional manual binding connections, and improves the positioning accuracy and connection strength during the installation of prefabricated wall panels.

[0023] like Figures 1-5 As shown, the vertical meniscus 131 is fastened to one side of the vertical beam reinforcement frame 101; the inner arc surface of the vertical meniscus 131 is in close contact with the surface of the steel reinforcement of the vertical beam reinforcement frame 101 to ensure a reliable connection; the vertical meniscus 131 and the vertical beam reinforcement frame 101 are tied and fixed by tie wires passing through the binding port 133; during the binding process, the tie wires are tightened by tools to make the vertical meniscus 131 stable and not displaced; this method replaces the traditional operation of manually tying steel reinforcement, enhancing the rigidity and shear resistance of the connection; during subsequent concrete pouring, the vertical meniscus 131 can provide a stable positioning point to ensure the overall stability of the structure.

[0024] like Figures 1-5 As shown, precast wall panel bodies 104 are symmetrically arranged on both sides of the vertical beam steel reinforcement frame 101. The precast wall panel bodies 104 are hoisted to both sides of the vertical beam steel reinforcement frame 101 by a crane and kept in a vertically positioned state. A wall panel steel reinforcement skeleton 141 is set inside the precast wall panel body 104. The wall panel steel reinforcement skeleton 141 is formed by welding or binding several longitudinal and transverse steel bars to form a frame structure, and is embedded in the concrete during the wall panel forming process. The ends of the wall panel steel reinforcement skeleton 141 extend outward and expose the side of the precast wall panel body 104 for connection with the vertical beam steel reinforcement frame 101. Through this structural design, the wall panel body 104 can be integrated with the main steel reinforcement frame, thereby improving the overall structural performance and connection strength of the component.

[0025] like Figures 1-5As shown, the horizontal semi-circular plate 132 is fastened to one side of the wall panel reinforcement cage 141; the inner side of the horizontal semi-circular plate 132 is tightly fitted with the reinforcement of the wall panel reinforcement cage 141, forming a stable covering state; the horizontal semi-circular plate 132 and the wall panel reinforcement cage 141 are tied and fixed by the tie wires passing through the binding port 133 to ensure that the structure does not slide or shift during assembly; through the structural arrangement of the vertical semi-circular plate 131 and the horizontal semi-circular plate 132 perpendicular to each other, the cross-shaped butt buckle 103 can realize the rigid connection between the vertical beam reinforcement cage 101 and the wall panel reinforcement cage 141 in three-dimensional space; this design not only simplifies the installation process, but also significantly improves the assembly strength and construction efficiency, and effectively solves the problems of inaccurate positioning and loose binding in traditional wall panel connection methods.

[0026] like Figure 1 As shown, a steel hoop 102 is nested on the outside of the vertical beam steel reinforcement frame 101. The steel hoop 102 is a closed ring structure that tightly wraps around the outside of the vertical beam steel reinforcement frame 101. The steel hoop 102 is used to limit the lateral deformation of the steel reinforcement frame members and improve the overall bending stiffness and stability of the steel cage. The steel hoop 102 is tied and fixed to multiple intersections of the vertical beam steel reinforcement frame 101 with tie wires to form multiple constraint points, enhancing the coordination and tensile strength between components. This structural setting further improves the ability of the vertical beam steel reinforcement frame 101 to bear concentrated loads during the connection with the precast wall panel, ensuring the safety and durability of the entire connection structure during construction and use.

[0027] The working principle of this utility model is as follows:

[0028] When in use, first tie the steel bars and steel hoops 102 together with tie wire to form a vertical beam steel frame 101. Then, use a crane to hoist the precast wall panel body 104 onto both sides of the vertical beam steel frame 101. Then, according to the position of the wall panel steel frame 141, install the cross butt buckles 103 one by one.

[0029] During installation, first fasten the vertical half-meniscus 131 to one side of the vertical beam steel reinforcement frame 101, then tie and fix the vertical half-meniscus 131 and the vertical beam steel reinforcement frame 101 with tie wires, then fasten the horizontal half-meniscus 132 to one side of the wall panel steel reinforcement frame 141, and tie and fix the horizontal half-meniscus 132 and the wall panel steel reinforcement frame 141 with tie wires.

[0030] The precast wall panel body 104 is connected to the vertical beam steel frame 101 by the cross-shaped butt buckle 103, which is quick and convenient. It can be adjusted at will according to the height of the wall panel steel frame 141. Compared with the traditional single wire binding and fixing, the connection by the cross-shaped butt buckle 103 is more stable and firm.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
