Description

Technical Field

[0001] This utility model specifically relates to a six-sided connector structure for prefabricated buildings, belonging to the field of building engineering. Background Technology

[0002] With the acceleration of the industrialization of construction, steel structure buildings can achieve modularization and prefabrication, thereby improving construction efficiency and precision, as well as excellent mechanical properties, and are widely used in commercial, industrial and residential buildings. Steel structure connection is a key link to ensure the integrity and safety of the structure. The structure of the connectors must not only meet the different connection methods of the steel structure, but also meet the strength, stiffness, durability and seismic resistance of the building structure. At present, the existing connector structures have the problem of insufficient manufacturing precision. If the manufacturing precision is insufficient, it may lead to a decline in the overall performance of the structure, making it difficult to ensure that they can effectively transmit force and stress. Moreover, the current design is relatively complex, which increases the difficulty of design and construction.

[0021] 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 protection scope of the present utility model.

[0022] Please see Figures 1-8 As shown, Figures 1-8The diagram schematically illustrates a six-sided connector structure for prefabricated buildings according to the present invention.

[0023] A six-sided connector structure for prefabricated buildings includes a six-sided connector 1, a beam 4, and a column 5. The six-sided connector 1 is characterized by comprising a sealing plate 1.2 and a square tube 1.1. The two ends of the square tube 1.1 are ports 1.13, which are connected to the sealing plate 1.2 via welds 2. Each of the four sides of the square tube 1.1 has a circular hole 1.12, and symmetrical bolt holes 1.23 are provided around the circular holes 1.12 for fixing the beam 4, column 5, and six-sided connector 1 with bolts.

[0024] Among them, square tube 1.1 is made by cutting hollow steel tubes at equal intervals.

[0025] The circular hole 1.12 is surrounded by symmetrical bolt holes 1.23, which facilitates the bolts to fix the beam 4 and column 5, ensuring the stability of the beam 4 and column 5 under stress.

[0026] Among them, the cylindrical part 1.12 not only facilitates the movement of the wrench, but also facilitates the rapid flow of cement grout inside the connector 1, beam 4, and column 5 during grouting, so that the cement grout is injected densely and fully, increasing the integrity of the steel structure and meeting the requirements of the building structure in terms of strength, rigidity, durability, and seismic resistance.

[0027] Furthermore, a limiting groove 1.11 is provided at the port 1.13 of the square tube 1.1 to limit the sealing plate 1.2.

[0028] Furthermore, the sealing plate 1.2 is slightly smaller than the port of the square tube 1.1.

[0029] Among them, the sealing plate 1.2 is square.

[0030] Furthermore, the sealing plate 1.2 has beveled edges 1.24 at the four corners, and protrusions 1.22 are provided between the beveled edges 1.24 on the same side. The sealing plate 1.2 is connected to the limiting groove 1.11 through the protrusions 1.22.

[0031] Furthermore, a weld gap 3 and a weld notch 3.1 are formed between the sealing plate 1.2 and the square tube 1.1.

[0032] Among them, the weld gap 3 can reduce the heat-affected zone of the welding area, reduce welding deformation and stress concentration, thereby improving the quality and performance of the welded joint; the weld notch 3.1 can ensure that the molten metal during welding can fully penetrate to the root of the joint, and at the same time, the six-sided connector 1 has no dead corners during hot-dip galvanizing, which facilitates more uniform hot-dip galvanizing and prevents the galvanizing water from accumulating at the four corners.

[0033] In this utility model, before installation, the four walls of the square tube 1.1 are first mechanically punched with round holes 1.12 and bolt holes 1.23. Limiting grooves 1.11 are made at the port 1.13 positions on both sides of the square tube 1.1. Round holes 1.12, protrusions 1.22, bolt holes 1.23, bevels 1.24 and four symmetrical bolt holes are mechanically punched and cut to form a sealing plate 1.2.

[0034] The four sides of the square tube 1.1 wall and the sealing plate 1.2 at the two ports 1.13 of the square tube 1.1 form a six-sided connector 1, which connects the six sides to the beam 4 and column 5.

[0035] like Figures 5-8 As shown, when the building structure is multi-story, if the center of the six-sided connector 1 needs to be connected to the beam 4 on the left and right, front and back, and top and bottom of the column 5, the beam 4 and column 5 only need to be connected to the bolt holes 1.23 on the six-sided connector 4 with bolts. Similarly, when the building structure is single-story, it only needs to be connected to the beam 4 on the right and front, and to the column 5 at the bottom. The beam 4 and column 5 are connected to the bolt holes 1.23 on the six-sided connector 1 with bolts. At the same time, depending on the position of the beam 4 and column 5 in the building structure, the T-shaped connection beam 4 and column 5 and the corner connection beam 4 and column 5 only need to be connected to the corresponding beam 4 and column 5 face of the six-sided connector 4 with bolt holes 1.23 to achieve connection of all six faces to the beam 4 and column 5, thus satisfying the connection methods of different types of building structures.

[0036] The beneficial effects of this utility model are:

[0037] The six-sided connector of this utility model consists of a sealing plate 1.2 and a square tube 1.1. Four sides of the square tube 1.1 can be connected to the beam 4 and the column 5, which meets the connection requirements of normal building structures. Moreover, after the two ends of the square tube 1.1 are welded with the sealing plate 1.2, all six sides can be connected to the beam 4 and the column 5, thereby meeting the connection requirements of different types of building structures, thereby improving manufacturing precision and reducing construction difficulty.

[0038] In this utility model, an installation method for a six-sided connector structure used in prefabricated buildings is as follows:

[0039] Step 1: The sealing plate 1.2 and the square tube 1.1 are combined. The sealing plate 1.2 is connected to the limiting groove 1.11 of the square tube 1.1 through the protrusion 1.22. The limiting groove 1.11 of the square tube 1.1 is exactly aligned with the protrusion 1.22 of the sealing plate 1.2. The hypotenuses 1.24 of the four corners of the sealing plate 1.2 are in contact with the inner wall of the port 1.13 of the square tube 1.1. A weld gap 3 and a notch 3.1 are formed between the sealing plate 1.2 and the square tube 1.1.

[0040] Step 2: Weld gap 3 is treated as weld 2. The sealing plate 1.2 and square tube 1.1 of the welded six-sided connector 1 are hot-dip galvanized to ensure that there are no dead corners in the galvanization inside and outside the six-sided connector 1.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
