Description

Technical Field

[0001] This utility model relates to the field of prefabricated beam-column structure technology, specifically to a steel structure beam-column for prefabricated buildings. Background Technology

[0002] Prefabricated construction refers to a new type of construction method in which the walls of a building are prefabricated in a factory and then transported to the construction site for assembly. It is also one of the main construction methods in many buildings today because it is quick to assemble, which can greatly shorten the construction period and enable lightweight design to reduce transportation costs. Because it is prefabricated, the beams and columns are also assembled by splicing.

[0003] Currently, beam-column splicing mainly relies on screws for connection. However, simple screw connections have certain stability defects and are not stable enough. Auxiliary components are needed to ensure the stability of the connection. However, the current auxiliary components are cumbersome to use because they are additional. Therefore, a steel structure beam-column for prefabricated buildings is proposed. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the technical problem is: a steel structure beam and column for prefabricated buildings, including a vertical column, a placement groove is opened on one side of the vertical column, a connecting block is inserted into the placement groove, a positioning groove is opened in the connecting block, the positioning groove is a T-shaped structure, a limiting block is inserted into the positioning groove, a horizontal beam is fixedly connected to the middle of one side wall of the limiting block, the horizontal beam is detachably connected to the placement groove through the connecting block, and a side sealing plate is detachably connected to the side of the vertical column located at the opening of the placement groove.

[0005] As a preferred technical solution of this utility model, baffles are fixedly connected to the opposite sides of the placement groove, a placement plate is fixedly connected to the connecting block and the opposite side wall of the placement groove, a limiting plate is fixedly connected to the edge of the placement plate and the baffle, the placement plate is inserted into the placement groove, and a screw hole is opened in the inner wall of the placement groove.

[0006] As a preferred technical solution of this utility model, two plug-in plates are fixedly connected to the side walls opposite to the baffle and the limiting plate. A sleeve groove is opened on the side wall opposite to the limiting plate and the plug-in plate. Anti-retraction blocks are fixedly connected to both the sleeve groove and the side wall opposite to the plug-in plate. The anti-retraction blocks on the two side walls inside the sleeve groove have an interlocking structure and correspond to the anti-retraction blocks on the plug-in plate.

[0007] As a preferred technical solution of this utility model, a top sealing plate is fixedly connected to the top of the limiting block. The size of the top sealing plate is the same as the size of the top side wall of the connecting block. Through holes are opened on the top sealing plate, the limiting block and the connecting block, and screws are inserted into the through holes.

[0008] As a preferred technical solution of this utility model, the side wall of the vertical column above the placement groove is connected to a pressing plate by screws in a detachable manner. The bottom side wall of the pressing plate is attached to the top side wall of the top sealing plate. The side wall of the vertical column below the placement groove is fixedly connected to a top support plate. The top side wall of the top support plate is attached to the bottom side wall of the connecting block. The top support plate and the pressing plate are wedge-shaped structures.

[0009] This utility model has the following advantages: Because the placement slots corresponding to the placement plates are pre-cut on the vertical columns, during assembly, it is only necessary to insert the placement plates into the placement slots and then insert the limiting blocks into the positioning slots to achieve the assembly and splicing of the vertical columns and horizontal beams. Then, screws are used for reinforcement. The vertical columns and horizontal beams can be disassembled and assembled by plugging and unplugging, which can greatly shorten the assembly and splicing time. In addition, the connecting blocks and their related components can be pre-fixed on the vertical columns and then transported to the site for assembly, saving the time spent on additional component installation.

[0010] The side sealing plates, pressing plates, and top support plates can be used to reinforce the connection, ensuring the stability of the connection and guaranteeing that the vertical columns and side sealing plates after connection can provide stable support for the assembled wall.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3This utility model discloses a steel structure beam and column for prefabricated buildings, including a vertical column 1. A mounting groove 7 is provided on one side of the vertical column 1. A connecting block 5 is inserted into the mounting groove 7. A positioning groove 11 is provided in the connecting block 5. The positioning groove 11 has a T-shaped structure. A limiting block 12 is inserted into the positioning groove 11. A horizontal beam 6 is fixedly connected to the middle of one side wall of the limiting block 12. The horizontal beam 6 is detachably connected to the mounting groove 7 through the connecting block 5. A side sealing plate 2 is detachably connected to the side of the vertical column 1 located at the opening of the mounting groove 7.

[0017] A baffle 8 is fixedly connected to both sides of the mounting groove 7. A placement plate 9 is fixedly connected to the side wall of the mounting groove 7 and the connecting block 5. A limiting plate 10 is fixedly connected to the side edge of the placement plate 9 and the baffle 8. The placement plate 9 is inserted into the mounting groove 7. A screw hole is opened in the inner wall of the mounting groove 7. Two plug-in plates 15 are fixedly connected to the side wall of the baffle 8 and the limiting plate 10. A sleeve groove 14 is opened in the side wall of the limiting plate 10 and the plug-in plate 15. Anti-retraction blocks 16 are fixedly connected to both the side wall of the sleeve groove 14 and the side wall of the plug-in plate 15. The anti-retraction blocks 16 on both sides of the inner side wall of the sleeve groove 14 are interleaved and correspond to the anti-retraction blocks 16 on the plug-in plate 15.

[0018] The technical advantages of this solution are as follows: the placement plate 9 is inserted into the placement groove 7 in advance, and then the side sealing plate 2 is connected to the side opening of the placement groove 7 to achieve the initial fixation of the connecting block 5 and the vertical column 1. After the vertical column 1 and the side sealing plate 2 are transported to the site, the limiting block 12 is simply snapped into the positioning groove 11, and then the vertical column 1 and the side sealing plate 2 can be assembled by fixing with screws. This method can greatly increase the convenience of assembling the vertical column 1 and the side sealing plate 2, and can avoid the time wasted by component installation on the overall assembly and splicing, thereby improving the overall assembly efficiency.

[0019] A top sealing plate 13 is fixedly connected to the top of the limiting block 12. The size of the top sealing plate 13 is the same as the size of the top side wall of the connecting block 5. The top sealing plate 13, the limiting block 12 and the connecting block 5 are all provided with through holes, and screws are inserted into the through holes. The side wall of the vertical column 1 above the placement groove 7 is detachably connected to the pressing plate 3 by screws. The bottom side wall of the pressing plate 3 is attached to the top side wall of the top sealing plate 13. The side wall of the vertical column 1 below the placement groove 7 is fixedly connected to the top support plate 4. The top side wall of the top support plate 4 is attached to the bottom side wall of the connecting block 5. The top support plate 4 and the pressing plate 3 are wedge-shaped structures.

[0020] The technical benefits of this solution are as follows: By connecting the pressing plate 3 and the top support plate 4 to the upper and lower sides of the mounting groove 7 respectively, the connecting block 5 can be supported, ensuring the stability of the connecting block 5 after connection. This also ensures the stability between the horizontal beam 6 and the vertical column 1. Furthermore, the pressing plate 3 can also press the limiting block 12, ensuring that the limiting block 12 is stably inserted into the positioning groove 11, increasing safety in the later stages. Disassembly only requires unscrewing the screws and then pulling out the components one by one.

[0021] Specifically, in use, the placement plate 9 is inserted into the placement groove 7. As the placement plate 9 is inserted, the connecting groove 14 will also be inserted into the corresponding connecting plate 15. The anti-retraction block 16 is compressed and deformed under pressure. After being fully inserted, the unfolded anti-retraction block 16 will block and limit each other, thereby keeping the placement plate 9 stably in the placement groove 7, forming an anti-retraction protection function. Then, the side sealing plate 2 is connected to the side opening of the placement groove 7 with screws to seal the internal space of the placement groove 7. Then, the limiting block 12 is inserted into the positioning groove 11. Then, the screws are threaded through the through holes on the connecting block 5 and the limiting block 12 and finally threaded into the screw hole in the placement groove 7 to achieve reinforcement. Finally, the pressing plate 3 is connected to the vertical column 1. Then, the screws are threaded through the through holes on the pressing plate 3 and the top sealing plate 13 and threaded into the screw hole at the top of the connecting block 5 for secondary pressing reinforcement. With the support of the top support plate 4, the stability and smoothness of the connection between the horizontal beam 6 and the vertical column 1 can be fully guaranteed.

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.

[0023] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
