Description

Technical Field

[0001] This utility model relates to the field of steel node technology, and in particular to an auxiliary support connection steel node. Background Technology

[0002] Auxiliary support connection steel nodes are key parts in steel structures used to connect auxiliary supports to the main structure (such as beams, columns, etc.). Their main function is to effectively transfer the internal forces (such as tension or compression) of the auxiliary supports to the main structure, thereby enhancing the overall stability of the structure.

[0003] Existing patent (publication number: CN216664478U) discloses "a prefabricated steel frame beam-column joint, which consists of a column with a cantilever section, a steel beam, an end plate, bolts, a cover plate, and stiffening ribs. The core of the joint is the column with the cantilever section and the steel beam; on-site, they are connected by bolts to the inclined end plates, wherein the inclined end plates are flush with the upper flange of the steel beam and extend outward at the lower flange of the steel beam. To enhance the rigidity of the joint, stiffening ribs are provided on both sides of the extended portion of the lower flange of the end plate, and the upper flange of the steel beam is connected by bolts to the cover plate. This prefabricated steel frame beam-column joint has excellent strength, rigidity, and deformation capacity. During the construction phase, auxiliary supports can be reduced, the steel beam is easy to position and install, on-site welding can be avoided, and the construction quality of the joint can be guaranteed. The novelty of the joint lies in the end plate extending outward at the lower flange, the inclined placement of the end plate, and the addition of a cover plate at the upper flange, thereby achieving the goal of a strong joint, weak components, and simple and easy splicing."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: When using existing steel nodes, the beams or columns that need to be connected to the outside are usually transported to the construction site for assembly. In actual operation, the positions of the installed beams and columns need to be checked, and the operation is cumbersome when using the whole thing, resulting in poor overall practicality.

[0005] Therefore, those skilled in the art have provided an auxiliary support connection steel node to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary support connection steel node. By applying it to small-scale prefabricated concrete beam-column structures, where the columns are continuous columns of three stories or less, this invention solves the problem of on-site installation and calibration of columns in multi-story buildings during the construction of traditional prefabricated houses, thereby improving the practicality of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An auxiliary support connecting steel node includes a pre-embedded mechanism, wherein column mechanisms are fixedly installed at both the upper and lower ends of the pre-embedded mechanism by concrete pouring, and crossbeam mechanisms are fixedly installed around the pre-embedded mechanism by concrete pouring.

[0009] The pre-embedded mechanism includes a first upright plate, and a second upright plate is fixedly installed in the middle of the first upright plate by welding. Both the first and second upright plates have multiple through holes at equal intervals on their surfaces.

[0010] Furthermore, both sides of the first upright plate and one side of the second upright plate are provided with multiple fixing bolts with equally spaced threads.

[0011] Furthermore, splicing plates are fixedly installed on both sides of the first upright plate and one side of the second upright plate by multiple fixing bolts.

[0012] Furthermore, a connecting plate is fixedly installed at the middle position of one side of the first upright plate by welding.

[0013] Furthermore, the column mechanism includes multiple continuous ribs, and multiple first stirrups are fixedly provided on the outer surface of the multiple continuous ribs.

[0014] Furthermore, a first concrete layer is fixedly provided on the outer surface of each of the multiple longitudinal reinforcing bars and the first stirrup.

[0015] Furthermore, the beam mechanism includes multiple right-angled negative ribs, and multiple second stirrups are fixedly provided on the outer surface of the multiple right-angled negative ribs.

[0016] Furthermore, a second concrete layer is fixedly provided on the outer surface of each of the right-angled negative reinforcement bars and the second stirrup.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model proposes an auxiliary support connection steel node. In traditional prefabricated housing construction, the columns of multi-story buildings need to be installed and calibrated on-site, which is quite cumbersome. This device, through the design of the pre-embedded mechanism, allows the columns to be fixed in advance, reducing the workload of on-site installation and calibration and improving construction efficiency. At the same time, the pre-embedded mechanism, column mechanism and beam mechanism are fixedly connected by concrete pouring, ensuring the strength and stability of the connection. The design of the continuous reinforcement, stirrups and concrete layer further enhances the load-bearing capacity of the structure. The splicing plate design of the pre-embedded mechanism can be combined as needed to adapt to beam connections in different directions, improving the flexibility and practicality of the device.

[0029] An auxiliary support connecting steel node includes a pre-embedded mechanism 3. The pre-embedded mechanism 3 has column mechanisms 1 fixedly installed at both its upper and lower ends by concrete pouring, and beam mechanisms 2 fixedly installed around the pre-embedded mechanism 3 by concrete pouring.

[0030] Specifically, by setting up a pre-embedded mechanism 3, combined with the column mechanism 1 and the beam mechanism 2, the device can be guaranteed to have the basic connection function of steel node and the beam and column support function. By fixing the pre-embedded mechanism 3, column mechanism 1 and beam mechanism 2 with concrete pouring, the connection strength between the pre-embedded mechanism 3, column mechanism 1 and beam mechanism 2 is guaranteed, while the overall strength of the device is guaranteed, so that it meets the usage requirements in the field of housing construction.

A first concrete layer 102 is fixedly provided on the outer surface of the multiple longitudinal ribs 101 and the first stirrups 103.

[0032] Specifically, by providing a continuous reinforcing bar 101, combined with the external first stirrup 103, the overall strength of the column mechanism 1 as a column can be guaranteed. The continuous reinforcing bar 101 and the first stirrup 103 are fixed together by tie wire, which makes it easy for users to fix the continuous reinforcing bar 101 and the first stirrup 103 to a suitable position. By providing a first concrete layer 102, which is made of C30 concrete, the overall strength of the structure can be guaranteed.

[0033] The beam mechanism 2 includes multiple right-angled negative reinforcement bars 201, multiple second stirrups 203 are fixedly provided on the outer surface of the multiple right-angled negative reinforcement bars 201, and a second concrete layer 202 is fixedly provided on the outer surface of both the multiple right-angled negative reinforcement bars 201 and the second stirrups 203.

[0034] Specifically, by setting right-angled negative reinforcement 201, combined with the external second stirrup 203, the overall strength of the beam mechanism 2 is facilitated during use. The right-angled negative reinforcement 201 and the second stirrup 203 are fixed with tie wire, making it easy for the user to place the right-angled negative reinforcement 201 and the second stirrup 203 in a suitable position and fix them. By setting a second concrete layer 202, which is made of C30 concrete, the overall strength of the beam mechanism 2 can be guaranteed.

[0035] The pre-embedded mechanism 3 includes a first upright plate 303, a second upright plate 304 fixedly installed in the middle of the first upright plate 303 by welding, multiple through holes 305 are equally spaced on the surfaces of the first upright plate 303 and the second upright plate 304, multiple fixing bolts 302 are equally spaced threaded on both sides of the first upright plate 303 and one side of the second upright plate 304, splicing plates 301 are fixedly installed on both sides of the first upright plate 303 and one side of the second upright plate 304 by multiple fixing bolts 302, and a connecting plate 306 is fixedly installed in the middle of one side of the first upright plate 303 by welding.

[0036] Specifically, by providing a first upright plate 303 and a second upright plate 304, the embedded mechanism 3 can be easily connected to the T-shaped column during use. By providing multiple through holes 305 with equal spacing between them, the overall weight of the node can be reduced, and the user can easily position it. By providing fixing bolts 302 and splicing plates 301, when the user needs to connect beams in multiple directions, the user can combine the splicing plates 301 according to the usage situation and connect the beam mechanism 2, which facilitates the user's positioning and reduces the positioning difficulty when using prefabricated structures. By providing a connecting plate 306, it is beneficial to realize the basic connection function between the embedded mechanism 3 and the beam mechanism 2.

[0037] Working Principle: In this device, the embedded mechanism 3 is the core component, comprising a first upright plate 303 and a second upright plate 304, which are connected by welding and have multiple through holes 305 evenly spaced on their surfaces. The embedded mechanism 3 is fixedly connected to the column mechanism 1 and the beam mechanism 2 by concrete pouring, serving as a connection and support. The two sides and the middle of the embedded mechanism 3 are connected by fixing bolts 302 and splicing plates 301. The splicing plates 301 can be combined as needed to adapt to beam connections in different directions. The column mechanism 1 consists of multiple continuous reinforcing bars 101 and a first stirrup 103, with a first concrete layer 102 poured on its outer surface. The continuous reinforcing bars 101 and the stirrups are fixed by tie wires to ensure the strength and stability of the column. The column mechanism 1 is fixedly connected to the upper and lower ends of the embedded mechanism 3 by concrete pouring to form an integral structure. The beam mechanism 2 consists of multiple right-angled negative reinforcing bars 201 and a second stirrup 203, with a second concrete layer 202 poured on its outer surface. Right-angled negative reinforcement 201 and stirrups are fixed with tie wire to ensure the strength and stability of the beam. The beam mechanism 2 is fixedly connected to the embedded mechanism 3 around its perimeter by concrete pouring to form an integral structure. Through the combination of the embedded mechanism 3, the column mechanism 1, and the beam mechanism 2, this device realizes the connection and support functions of the beam and column. The through hole 305 and splicing plate 301 design of the embedded mechanism 3 make the connection of the beam and column more flexible and reduce the workload of on-site installation and calibration.
