Description

Technical Field

[0001] This utility model relates to a prefabricated component for prefabricated buildings. Background Technology

[0002] With the rapid development of industrialized construction, prefabricated buildings are increasingly widely used in the construction industry due to their advantages such as high construction efficiency, low environmental pollution, and easy quality control. Prefabricated components, as the core components of prefabricated buildings, directly affect the overall strength, stability, and construction efficiency of the building through their structural design and connection methods.

[0003] In existing technologies, prefabricated components for prefabricated buildings are mostly cast from concrete, and connections between components are often achieved through bolts, embedded parts, and other methods. However, traditional prefabricated components suffer from problems such as insufficient structural strength, unstable connections, and cumbersome installation processes. For example, some prefabricated components are prone to deformation during transportation or installation due to the lack of internal reinforcing structures; the connections between components are mostly rigid, which are prone to loosening or even breakage under external forces such as earthquakes; at the same time, unreasonable design of connecting components also leads to low installation efficiency and increased construction costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems of insufficient structural strength, poor connection stability, low installation efficiency and poor seismic performance in the existing technology, and to provide a prefabricated building component with high structural strength, low cost and good seismic performance.

[0005] A prefabricated component for prefabricated buildings includes an outer frame, with a plurality of studs on the outer surface of the outer frame and a through hole in the middle of each stud; and a plurality of steel wire ropes inside the outer frame, with the ends of the steel wire ropes extending out from the through holes, and the steel wire ropes being connected to the inner wall of the outer frame by welding when straightened.

[0006] Two adjacent prefabricated components are connected by several connecting posts. The connecting posts have left and right threads inside, with the left and right threads having opposite directions of rotation. Both ends of the connecting posts are provided with springs. After the studs between two adjacent prefabricated components are aligned, the connecting posts are fitted between the two prefabricated components. The connection between the connecting posts and the two studs is completed by rotation. After the connection is completed, the springs at both ends of the connecting posts abut against the ends of the two prefabricated components.

[0007] Furthermore, the outer surface of the connecting column is hexagonal. This hexagonal design allows on-site operators to complete the connection without special tools, reducing the skill requirements for construction workers and thus improving the connection efficiency of adjacent precast components and shortening the construction cycle.

[0008] Furthermore, the stud is connected to the outer frame by welding. Welding is a simple and low-cost operation, suitable for mass production, and can ensure the consistency of stud positions in different prefabricated components, thereby improving the interchangeability of components.

[0009] Furthermore, the stud and the outer frame are integral castings. After casting, external threads are machined onto the surface of the stud by surface tapping, and through holes are machined by drilling. This integral structure avoids weld fatigue problems that may occur with welded connections, but it is more expensive. It is suitable for applications with higher quality requirements and, with the aid of molds, is suitable for rapid mass production.

[0010] Furthermore, the wire ropes are distributed in a crisscross pattern, both horizontally and vertically; in a single precast component, the number of horizontal wire ropes is four to six, and the number of vertical wire ropes is four to eight. This large number of wire ropes enhances safety; even if a few wire ropes are accidentally damaged, the remaining wire ropes can still share the load, reducing the risk of sudden component failure.

[0011] Furthermore, after the connecting post is connected to the two studs, the spring is in a compressed state. The compressed spring generates an outward thrust, which acts on the ends of the two components respectively, ensuring that the threads of the connecting post and the studs remain tightly engaged and eliminating thread clearance.

[0012] Furthermore, after the outer frame is welded and fixed to the steel wire rope, a filling material, such as foam or foamed concrete, is filled into the hollow area of ​​the outer frame by pouring or foaming. The filling material tightly wraps the steel wire rope, preventing direct contact between the rope and air or moisture, while also enhancing the overall rigidity of the component through its own strength. This protects the internal structure, and the foam or foamed concrete isolates it from external corrosive media, extending the service life of the steel wire rope.

[0013] Furthermore, the outer frame, studs, and connecting posts are all made of metal.

[0014] Furthermore, the wire rope is composed of at least six strands of wire wound together. When the wire rope is subjected to tension, the tension can be evenly distributed to each strand of wire, preventing individual strands from breaking due to overload.

[0015] Compared with traditional reinforced concrete structures, the use of steel wire rope in this scheme has the following advantages:

[0016] The steel wire ropes are arranged in a crisscross pattern, forming a "net-like" reinforcing structure that can disperse external forces from multiple directions, improving the overall shear and tensile strength of the components. Furthermore, under the same strength requirements, the self-weight of the steel wire ropes is usually lower than that of traditional steel bars. Combined with lightweight filler materials such as foam, the overall weight of prefabricated components can be significantly reduced, facilitating transportation and installation.

[0017] Finally, steel wire ropes have a certain degree of flexibility, and when subjected to alternating loads such as earthquakes, they can buffer some of the stress through slight deformation. Combined with the spring structure at both ends of the connecting column, this further enhances the seismic performance of the component. In contrast, traditional steel bars are more rigid and are prone to breakage due to brittle deformation under severe vibration, resulting in a relatively weaker seismic buffering effect.

[0026] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0027] Example 1:

[0028] As shown in Figures 1-7, a prefabricated component for assembled buildings includes an outer frame 1, which is made of Q235B steel with a rectangular cross-section and a wall thickness of 8mm. Sixteen studs 2 are evenly distributed on the outer surface of the outer frame 1. The studs 2 are connected to the outer frame 1 by welding. A through hole 21 is provided in the center of each stud 2, and external threads are machined on the surface of each stud 2.

[0029] The outer frame 1 has eight steel wire ropes 4 inside, including four horizontal steel wire ropes 4 and four vertical steel wire ropes 4, which are distributed alternately in the horizontal and vertical directions. The ends of the steel wire ropes 4 extend from the through holes 21 and are connected to the inner wall of the outer frame 1 by welding when straight. The part of the steel wire rope 4 that exceeds the through holes 21 is cut off by hydraulic shears, and the end of the steel wire rope 4 after cutting is flush with the edge of the through holes 21.

[0030] After the outer frame 1 and the steel wire rope 4 are welded and fixed, foamed concrete 3 is poured into the hollow area of ​​the outer frame 1 to completely wrap the steel wire rope 4, and the outer frame 1, steel wire rope 4 and stud 2 are combined to form a complete prefabricated component structure.

[0031] Two adjacent prefabricated components are connected by four connecting columns 5. The connecting columns 5 have a left thread 51 and a right thread 52 inside, with the left thread 51 and the right thread 52 having opposite directions of rotation. Both ends of the connecting columns 5 are equipped with springs 7, and the outer surface of the connecting columns 5 is hexagonal.

[0032] After aligning the studs 2 between two adjacent precast components, the connecting post 5 is fitted between the two precast components. A wrench is used to clamp the hexagonal outer surface of the connecting post 5 and rotate it to complete the connection between the connecting post 5 and the two studs 2. After the connection is completed, the springs 7 at both ends of the connecting post 5 abut against the ends of the two precast components, and the springs 7 are in a compressed state.

[0033] In this embodiment, the prefabricated building components are constructed by first transporting individual prefabricated components to the construction site, then aligning the studs 2 of adjacent prefabricated components and connecting them using connecting posts 5. The hexagonal outer surface of the connecting post 5 facilitates wrench gripping. During rotation, the left thread 51 and right thread 52 engage with the external threads of the two studs 2 respectively, achieving a quick connection. After connection, the spring 7 is compressed, applying continuous elastic pressure to the two prefabricated components to ensure connection stability. Simultaneously, the steel wire rope 4 inside the outer frame 1 and the foamed concrete 3 work together to improve the structural strength and seismic performance of the components.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
