Description

Technical Field

[0001] This application belongs to the field of building construction technology, and in particular relates to a prefabricated beam-column connection component. Background Technology

[0002] Common beam-column connection components are primarily used to fix and install crossbeams on columns. Generally, these components are connected to the column by sleeve and welding, or by sleeve and screwing, while they are screwed to the crossbeam.

[0003] The above-mentioned components mainly consist of a central cylinder and side protruding parts, the former being used to connect the columns and the latter being used to connect the crossbeams.

[0004] For example, Chinese utility model patent with authorization announcement number CN222862548U and authorization announcement date of May 13, 2025 discloses a beam-column connection structure for building construction, which mainly includes: column, beam, beam one, beam two, connecting cylinder, fixing ring, connecting component, connecting surface, beam locking joint, fixing ring locking joint, concave structure, and inclined structure.

[0005] The connection structure in this utility model patent has the following advantages: it is particularly suitable for beams of different heights and beams that are eccentric to the column. The beam locking joint is fixed to the lower end of the beam, and the fixing ring locking joint is fixed to the fixing ring. The connection between the beam and the fixing ring generates downward stress, which is transferred to the column, thereby increasing the stability of the beam-column connection.

[0006] However, in practical use, this connection structure still has at least the following shortcomings in practicality, specifically: The aforementioned connecting components cannot be installed between the upper part of the beam structure and the connecting cylinder, or between the connecting cylinder and the column. The connection strength at these two points can only be provided by welding. Therefore, it is very troublesome to dismantle the beam later, as the welding must be removed, which ultimately greatly reduces its practicality. Utility Model Content

[0007] This application provides a prefabricated beam-column connection assembly, the technical problem to be solved by which the beam-column connection method has both sufficient installation stability and a certain degree of ease of disassembly and assembly.

[0008] The technical solution adopted by this application to solve the above problems is: an assembled beam-column connection assembly, the structure of which includes a threaded cylindrical unit for sleeved with a column, a bent connecting plate unit disposed on the outer side of the threaded cylindrical unit and used for connecting a crossbeam, a connecting threaded member disposed on the bent connecting plate unit and used for installing the crossbeam, a fixing threaded member disposed on the bent connecting plate unit and used for connecting the threaded cylindrical unit, and a transverse protruding plate unit disposed on the inner side of the threaded cylindrical unit and used for installing the fixing threaded member from the inside out by transversely abutting against the column.

[0009] A further preferred technical solution is that the screw-in cylindrical unit includes a square cylindrical body with the transverse protrusion plate unit on its inner side, and two sets of side holes disposed on the square cylindrical body and located on both sides of the transverse protrusion plate unit for installing the fixing screw.

[0010] A further preferred technical solution is that the screw-in cylinder unit further includes a central opening disposed on the square cylinder and located between the two sets of side holes, and a fixing bolt disposed on the central opening and used to connect the column screw hole.

[0011] A further preferred technical solution is that the bent connecting plate unit includes side plates disposed on the outer side of the square cylinder and the vertical side of the crossbeam, an inclined plate disposed between the two side plates and used to leave installation space for the head of the fixing bolt, and two sets of plate openings disposed on the two side plates respectively and used to install the connecting bolt and the fixing bolt.

[0012] A further preferred technical solution is that the transverse protrusion plate unit includes two protrusion plates disposed on the inner side of the square cylinder, and a connecting plate disposed on the two protrusion plates and used to laterally abut against the column.

[0013] A further preferred technical solution is that the transverse protrusion plate unit further includes a through hole disposed on the connecting plate and used to pass through the fixing bolt.

[0014] A further preferred technical solution is that the transverse protrusion plate unit further includes a reinforcing plate disposed on the connecting plate and used to connect the inner side of the square cylinder.

[0015] A further preferred technical solution is that the screw-in cylinder unit also includes a base plate disposed on the outer side of the square cylinder and used to support the crossbeam.

[0016] A further preferred technical solution is that the lower end face of the screw-in cylinder unit is flush with the lower end face of the transverse protrusion plate unit.

[0017] A further preferred technical solution includes: an inverted L-shaped reinforcing plate disposed on the column and used to support the bolted cylinder unit and the transverse protrusion plate unit, and mounting bolts disposed on the inverted L-shaped reinforcing plate and used to connect the column.

[0018] The beneficial effects of this application include at least the following three points.

[0019] First, the connecting component is movably connected to both the column and the crossbeam, and the connection strength is sufficient, giving it the advantage of easy assembly and disassembly on the column. It can also be used to install 1-4 crossbeams, making it flexible and practical, and meeting the usage requirements of prefabricated structures.

[0020] Secondly, the bent connecting plate unit can fully connect the bolted cylinder unit and the crossbeam, and also allows for the effective installation of the fixing bolts without any positional interference between them.

[0021] Third, the transverse protrusion plate unit can provide sufficient transverse limiting effect between the bolted cylinder unit and the column, and also leave enough space for the fixed bolted parts to be installed from the inside to the outside, making the disassembly and assembly operation convenient and efficient.

Detailed Implementation

[0032] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.

[0033] like Figures 1-8 As shown, an assembled beam-column connection assembly includes a threaded cylindrical unit 1 for fitting a column a, a bent connecting plate unit 2 disposed on the outer side of the threaded cylindrical unit 1 for connecting a crossbeam b, a connecting threaded member 3 disposed on the bent connecting plate unit 2 for mounting the crossbeam b, a fixing threaded member 4 disposed on the bent connecting plate unit 2 for connecting the threaded cylindrical unit 1, and a transverse protruding plate unit 5 disposed on the inner side of the threaded cylindrical unit 1 and for mounting the fixing threaded member 4 from the inside out by laterally abutting against the column a.

[0034] In this embodiment, the connecting component has both sufficient installation stability and a certain degree of ease of assembly and disassembly, for the following reasons: First, the connecting component is sleeved and screwed onto column a, thus ensuring sufficient connection strength. It is also engaged and screwed onto beam b, which also ensures sufficient connection strength. Secondly, all of the above connection methods are movable connections, which are more convenient and faster to establish and disengage than welding.

[0035] Among them, column a is a square steel pipe, and beam b is an I-beam.

[0036] Furthermore, the reason why this connecting component belongs to a prefabricated structure mainly includes the following two points: First, when this connecting component is first used, it can be equipped with 1-4 crossbeams b, which provides ample flexibility and practicality. Secondly, when the connecting component is in normal use, all the crossbeams b are independent of each other. It is simple and convenient to install a new crossbeam b or to remove an existing crossbeam b, without affecting the installation stability of the other crossbeams.

[0037] The main body of the connecting assembly is made of galvanized steel, and its structure consists of: one screw-in cylinder unit 1, one to four bent connecting plate units 2, one to four sets of connecting screws 3, two times the number of fixing screws 4, and four transverse protruding plate units 5.

[0038] On the other hand, the connection between the screw-on cylindrical unit 1 and the column a is the foundation for the stable installation of the connecting component. The crossbeam b is fully connected to the screw-on cylindrical unit 1 through the integrated structure composed of the bent connecting plate unit 2, the connecting screw 3, and the fixing screw 4, which ultimately achieves high-strength fixation.

[0039] Finally, the transverse protrusion plate unit 5 mainly has the following two functions: First, fully engage column a to ensure it is fully fixed laterally to the bolted cylindrical unit 1, thus preventing significant lateral displacement of the latter. Second, sufficient and suitable internal space should be provided for the fixing screw 4 to be installed from the inside out.

[0040] It should be noted that if the inner side of the screw-in cylinder unit 1 is not provided with the transverse protrusion plate unit 5, the fixing screw 4 cannot be installed from the inside out. In this case, for the bent connecting plate unit 2, there are generally only two installation methods: one is to weld it to the screw-in cylinder unit 1, and the other is to use bolts to screw it together with the screw-in cylinder unit 1 and the column a.

[0041] The first method described above does not meet the requirements of prefabricated structures, resulting in reduced practicality, while the second method described above has relatively low connection strength. Therefore, conversely, this is the function and advantage of the transverse protruding plate unit 5.

[0042] The screw-in cylindrical unit 1 includes a square cylindrical body 101 with the transverse protrusion plate unit 5 on its inner side, and two sets of side holes 102 disposed on the square cylindrical body 101 and located on both sides of the transverse protrusion plate unit 5 for installing the fixing screw 4.

[0043] In this embodiment, the square cylindrical body 101 and the transverse protruding plate unit 5 are integrally formed. The inner and outer contours of the former are both square. The side holes 102 are not threaded. A set of the side holes 102 consists of 2-3 circular holes.

[0044] Accordingly, the connecting screw 3 and the fixing screw 4 are both common, commercially available bolt and nut combinations. The bolt of the fixing screw 4 extends outward at the side hole 102, and its nut is used to fasten the bent connecting plate unit 2.

[0045] The screw-in cylinder unit 1 further includes a central opening 103 disposed on the square cylinder 101 and located between the two sets of side holes 102, and a fixing bolt 104 disposed on the central opening 103 and used to connect the column screw hole a-1.

[0046] In this embodiment, no threads are provided on the central opening 103. Since bolts cannot be installed from the inside to the outside at the column a, only the inwardly screwed fixing bolt 104 can be used at the central opening 103, and the above-mentioned bolt and nut combination cannot be used.

[0047] Generally, the connection strength of the fixing bolt 104 used alone is less than the connection strength of the bolt and nut used together. Therefore, the number of the central openings 103 can be appropriately increased, as shown in the attached figure. Figure 1 As shown, the square cylindrical body 101 has 6 central openings 103 and 4 side openings 102 on one side plate, with the former having a larger number.

[0048] The bent connecting plate unit 2 includes side plates 201 disposed on the outer side of the square cylinder 101 and the vertical side of the crossbeam b, an inclined plate 202 disposed between the two side plates 201 and used to leave installation space for the head of the fixing bolt 104, and two sets of plate openings 203 disposed on the two side plates 201 respectively and used to install the connecting bolt 3 and the fixing bolt 4.

[0049] In this embodiment, the bent connecting plate unit 2 is integrally formed, and the two side plates 201 are respectively attached to the outer side of the square cylinder 101 and the central vertical surface of the I-beam. The former is screwed together by the fixing screw 4 and the latter is screwed together by the connecting screw 3, so that the crossbeam b can be stably installed on the square cylinder 101.

[0050] The term "inclined" in the inclined plate 202 refers to the fact that it is inclined relative to the central vertical surface of the I-beam and the outer surface of the square cylinder 101, and is neither parallel nor vertical.

[0051] Therefore, the inclined plate 202 is able to provide installation space for the head of the fixing bolt 104, ensuring that the positions of the two do not interfere with each other. Accordingly, when installing this connecting assembly, the bolted cylinder unit 1 is first installed on the column a, and then the crossbeam b is installed on the bolted cylinder unit 1.

[0052] On the other hand, no threads are needed at the opening 203 on the plate, and its position and number correspond to the crossbeam hole b-1. The upper and lower edges of the two side plates 201 and the one inclined plate 202 are all flush, and they vertically engage the inner bottom and inner top surfaces of the I-beam, thereby further improving the installation stability of the crossbeam b on the bolted cylinder unit 1.

[0053] The transverse protruding plate unit 5 includes two protruding plates 501 disposed on the inner side of the square cylinder 101, and a connecting plate 502 disposed on the two protruding plates 501 and used to laterally abut against the column a.

[0054] In this embodiment, the four inner sides of the square cylinder 101 are provided with the transverse protrusion plate unit 5, and the area enclosed by the four connecting plates 502 is also square, so as to fully fit the column a.

[0055] The transverse protrusion plate unit 5 has an isosceles trapezoidal cross-section, with a relatively short upper base that abuts against the column a, thereby enabling the transverse protrusion plate unit 5 to provide relatively large transverse support strength.

[0056] At this point, the two protruding plates 501 within the same transverse protruding plate unit 5 move closer to each other, meaning that the protruding plates 501 of two adjacent transverse protruding plate units 5 move further apart, ultimately leaving a relatively large installation space for the fixing screw 4. This is very practical; please refer to the appendix for details. Figure 6 .

[0057] The transverse protrusion plate unit 5 also includes a through hole 503 disposed on the connecting plate 502 and used to pass through the fixing bolt 104.

[0058] In this embodiment, the number and position of the through hole 503, the central opening 103 and the column screw hole a-1 are the same, and it is optional whether or not a thread is provided at the through hole 503.

[0059] The transverse protrusion plate unit 5 also includes a reinforcing plate 504 disposed on the connecting plate 502 and used to connect the inner side of the square cylinder 101.

[0060] In this embodiment, the reinforcing plate 504 is rectangular in shape, with its long side facing vertically. It is also staggered from the through hole 503 in the horizontal direction to ensure that the structural reinforcement of the reinforcing plate 504 does not affect the through connection of the fixing bolt 104.

[0061] The screw-in cylinder unit 1 also includes a base plate 105 disposed on the outer side of the square cylinder 101 and used to support the crossbeam b.

[0062] In this embodiment, the base plate 105 is a square ring, which can support and fix all up to four crossbeams b installed on the square cylinder 101. The base plate 105 and the square cylinder 101 are integrally formed, and the lower surface of the crossbeam b presses against the upper surface of the base plate 105.

[0063] The lower end face of the screw-in cylinder unit 1 is flush with the lower end face of the transverse protrusion plate unit 5.

[0064] In this embodiment, the upper and lower surfaces of the transverse protrusion plate unit 5 are flush with the upper and lower surfaces of the screw-in cylinder unit 1, thereby giving the former a larger vertical dimension and ultimately enabling it to provide relatively large transverse support strength.

[0065] The beam-column connection assembly also includes an inverted L-shaped reinforcing plate 6 disposed on the column a and used to support the bolted cylinder unit 1 and the transverse protrusion plate unit 5, and mounting bolts 7 disposed on the inverted L-shaped reinforcing plate 6 and used to connect the column a.

[0066] In this embodiment, the mounting bolt 7 is screwed into the auxiliary screw hole a-2 on the column a, and the four inverted L-shaped reinforcing plates 6 jointly support the screwed cylindrical unit 1.

[0067] On the other hand, another function of the transverse protruding plate unit 5 is, together with the threaded cylinder unit 1, to serve as the lower surface of the connecting assembly, giving the connecting assembly a relatively wide annular lower surface. This allows the inverted L-shaped reinforcing plate 6 to provide stable support and sufficient reinforcement. For details, please refer to the appendix. Figure 8 .

Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application.
