Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated building connection structure, and in particular relates to a prefabricated building beam-column steel structure connection component. Background Technology

[0002] In the field of prefabricated construction, the rapid and stable connection of beam-column structures is a key factor in ensuring the overall safety and construction efficiency of buildings. Traditional beam-column connection methods mostly rely on on-site welding or bolt tightening. While these methods meet the structural connection requirements to some extent, they have revealed many limitations in actual operation, hindering the further development and application of prefabricated construction technology.

[0003] While existing prefabricated connection components have shown some structural innovation, they still have key drawbacks. On the one hand, some components require complex tools or multiple adjustments to achieve positioning, resulting in low on-site construction efficiency; on the other hand, the component design lacks flexibility and is difficult to adapt to the support requirements of different building locations.

[0004] For example, fixed-position connectors cannot be adjusted in height or level, requiring additional shims or cutting, increasing construction risks; while standardized components are difficult to match the connection requirements of irregular structural nodes, limiting design freedom. In addition, existing technologies mostly focus on optimizing single functions, failing to systematically solve the synergistic problem of rapid installation, precise adjustment, and structural stability.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0032] Please see Figure 1-7 As shown, this utility model is a prefabricated building beam-column steel structure connection component. The core design concept of this component is to achieve rapid adjustment and convenient installation of the connection between prefabricated beams and prefabricated columns, thereby significantly improving the construction efficiency and connection quality of prefabricated buildings. It mainly includes two core parts: prefabricated column connection component 1 and prefabricated beam connection component 2.

[0033] The assembly column connecting component 1 includes a rectangular cylinder 11, which serves as the main support structure and is made of high-strength steel to ensure load-bearing capacity and stability. At least two sides of the rectangular cylinder 11 are fixed with U-shaped support seats 12 to support the assembly beam connecting component 2. Two pairs of vertically arranged rectangular through holes 13 are opened on opposite side walls of the U-shaped support seats 12 to provide positioning and fixing points for bolt connections. Symmetrically fixed to the upper ends of the two side walls of the U-shaped support seats 12 are outwardly extending guide plates. This design allows the U-shaped connecting seat 21 of the assembly beam connecting component to slide quickly and accurately into the U-shaped support seat 12, greatly simplifying the installation process.

[0034] The beam connection component 2 includes a U-shaped connecting seat 21 that mates with the inner wall of the U-shaped support 12. The opposite sidewalls of the U-shaped connecting seat 21 have a row of vertically evenly arranged transverse rectangular through holes 22, facilitating quick connection with the U-shaped support 12 via bolts. The U-shaped support 12 and the U-shaped connecting seat 21 are connected by four rows of bolts and nuts. The bolts are pre-inserted into the vertical rectangular through holes 13 and the transverse rectangular through holes 22, and the nuts are quickly tightened using a power tool to achieve a rapid connection.

[0035] At least one adjustable support 3 is threaded through the bottom of the U-shaped support 12. The adjustable support 3 includes a threaded rod 31. A threaded through hole 14 is provided on the U-shaped support 12 to mate with the threaded rod 31. A disc 32 is fixed to the upper end of the threaded rod 31. A handle 33 is fixed to the lower end of the threaded rod 31. During installation, the height and level of the assembled beam connecting component 2 can be quickly adjusted by rotating the handle 33, without the need for complex tools or long-term adjustments. The design of the adjustable support 3 and the guide plate enables rapid positioning and level adjustment of the assembled beam connecting component 2, significantly improving construction efficiency. The combination of bolt and nut connection and welding reinforcement ensures the stability of the connection, simplifies the installation process, and reduces construction difficulty. The combination of prefabricated components and on-site assembly ensures dual control of component quality and construction accuracy, improving the safety and durability of the overall structure.

[0036] After the bolts and nuts are secured, the connection between the U-shaped support 12 and the U-shaped connecting seat 21 is reinforced by on-site welding. This step ensures the permanent stability of the connection and improves the seismic performance of the overall structure.

[0037] The U-shaped connecting seat 21 of the precast beam connecting component 2 can be quickly placed into the U-shaped support seat 12 of the precast column connecting component 1. The horizontal state of the precast beam connecting component 2 is measured on-site, and its horizontal state is adjusted using the adjustable supports 3 below the U-shaped connecting seats 21 at both ends. During adjustment, the crane first lifts the precast beam connecting component 2, then adjusts the adjustable supports 3 before lowering it. Simultaneously, the axial position of the precast beam connecting component 2 between the two U-shaped support seats 12 can also be adjusted. After adjustment, four rows of bolts and nuts are installed to secure the connection between the precast column connecting component 1 and the precast beam connecting component 2. The U-shaped support seats 12 and U-shaped connecting seats 21 are reinforced again by welding before the secondary concrete pouring, achieving a stable and effective connection between the precast beam and the precast column.

[0038] Other necessary structures of the precast column connecting component 1 include a first rectangular base plate 15 fixed to the lower end of a rectangular cylinder 11. Several first reinforcing bar ends 16 are fixed to the bottom surface of the first rectangular base plate 15 and are embedded in the precast column. The precast column connecting component 1 is integrally cast and connected to the precast column. Several vent holes 17 are provided on the first rectangular base plate 15. Non-essential structures of the precast column connecting component 1 include a rectangular flange fixed to the upper end of the rectangular cylinder 11 during the precast assembly process, or installation bolts pre-embedded in the poured concrete during later concrete pouring.

[0039] Other necessary structures of the precast beam connecting component 2 include a second rectangular base plate 23 fixed to one end of a U-shaped connecting seat 21. Several second reinforcing bar ends 24 are fixed to the side of the second rectangular base plate 23 away from the U-shaped connecting seat 21. The second reinforcing bar ends 24 are embedded in the precast beam, and the precast beam connecting component 2 is integrally cast and connected to the precast beam.

[0040] like Figure 2-5 As shown, the number and position of the rectangular tubes 11 on the assembled column connecting component 1 vary, and they are used for prefabrication of support columns in different locations of prefabricated buildings, such as... Figure 2 The assembled column connecting component 1 shown is used for prefabricated support columns at building corners. Figure 3 The assembled column connecting member 1 shown is used for supporting the connection between two unidirectional assembled beam connecting members 2 in a building. Figure 4 The assembled column connecting component 1 shown is used for a prefabricated support column in the middle of the side of the building. For example... Figure 5 The assembled column connecting member 1 shown is used for supporting the connection between the four cross-shaped assembled beam connecting members 2.
