Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a pre-assembled structure of a steel structure corridor. Background Art

[0002] As is well known, a steel structure corridor refers to a structure that uses steel to build and connect two or more buildings, usually used to provide a convenient passage path and enhance the connectivity between buildings; there are mainly two forms in the manufacturing and construction of traditional steel structure corridors. One is bolt assembly connection, which is not only convenient for cutting and manufacturing and pre-assembly inspection and acceptance at the production end, but also convenient for disassembly, transportation and on-site assembly. The disadvantage is that more connection holes and connecting parts need to be designed during manufacturing. At the same time, the service life and strength may be reduced compared with welding through bolt connection; the second is divided into multiple welded modules. If the corridor is short, one welded module may be used, as shown in the Chinese invention patent with the publication number CN116591296A. However, the overall space occupied is large, and the manufacturing and processing efficiency of integral welding forming is not high. If the corridor is long, on-site welding or assembly is still required; in view of this, it is urgent to design a pre-assembled structure of a steel structure corridor to meet the needs of the production end, transportation end and construction end, and improve the engineering efficiency while ensuring the structural strength effect. Summary of the Utility Model

[0003] In order to overcome the deficiencies in the background art and solve the existing technical problems, the utility model discloses a pre-assembled structure of a steel structure corridor, which combines the use of clamping connection to optimize the engineering effect and efficiency.

[0004] To achieve the above invention purpose, the utility model adopts the following technical solutions:

[0005] A pre-assembled structure of a steel structure corridor includes two side trusses arranged side by side at intervals. A first channel steel and a second channel steel with corresponding notches are respectively arranged below and above each side truss; the side truss is composed of a plurality of Z-shaped unit trusses arranged side by side. The Z-shaped unit truss includes a first T-shaped steel and a second T-shaped steel located at the bottom and top respectively. The flange plates of the first T-shaped steel and the second T-shaped steel are parallel and correspondingly connected by diagonal braces; the widths of the flange plates of the first T-shaped steel and the second T-shaped steel are respectively adapted to the groove widths of the first channel steel and the second channel steel, and can respectively slide and be clamped into the corresponding first channel steel and second channel steel. A plurality of flat braces arranged at intervals along the length direction of the side truss are clamped between the two first channel steels and the two second channel steels.

[0006] Further, the diagonal braces of two adjacent Z-shaped unit trusses are arranged in parallel or one end is opposite.

[0007] Further, the first T-shaped steel and the second T-shaped steel of two adjacent Z-shaped unit trusses are correspondingly abutted.

[0008] Furthermore, the diagonal bracing member is a square pipe, and the two ends of the square pipe are respectively connected to the corresponding ends of the first T-shaped steel and the second T-shaped steel.

[0009] Furthermore, the horizontal bracing member is a third T-shaped steel, and the two end flanges of the third T-shaped steel respectively extend to the upper sides of the corresponding first channel steel or second channel steel.

[0010] Furthermore, the upper plate surface of the flange of the first T-shaped steel is higher than the top surface of the groove wall of the first channel steel, and the end flanges of the third T-shaped steel between the two first channel steels are correspondingly located on the upper plate surface of the flange of the corresponding first T-shaped steel.

[0011] Due to the adoption of the above-mentioned technical solution, the present utility model has the following beneficial effects:

[0012] The pre-assembled structure of the steel structure corridor disclosed by the present utility model divides the side truss of the corridor into multiple Z-shaped unit frames. Among them, a single Z-shaped unit frame is convenient for processing and manufacturing, and also convenient for transportation. The Z-shaped structure can also make the supporting force of the diagonal bracing member directly act on the first T-shaped steel and the second T-shaped steel, making the supporting force of the whole structure more uniform. More importantly, the Z-shaped unit frame can be easily clamped in the first channel steel and the second channel steel for positioning, that is, it is convenient for inspection and acceptance during pre-assembly production, and can also reduce a certain welding length when meeting the same strength requirements during on-site construction; In summary, the present utility model can reasonably utilize the steel structure to ensure the structural quality, and combines the clamping connection method, which greatly optimizes the efficiency of the corridor construction project.

[0017] Next, the technical solution of the present utility model will be described in conjunction with the drawings in the embodiments of the present utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, they are only corresponding to the drawings of the present utility model for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation:

[0018] Combined with the attached Figures 1 - 3 The pre-assembled structure of the steel structure connecting corridor described above includes two side trusses arranged side by side at intervals. A first channel steel 1 and a second channel steel 2 with corresponding notches are respectively provided below and above each side truss. The lengths of the first channel steel 1 and the second channel steel 2 can be welded and assembled according to actual needs. The side truss is composed of a plurality of Z-shaped unit frames arranged side by side. The Z-shaped unit frame includes a first T-shaped steel 3 and a second T-shaped steel 5 located at the bottom and top respectively. The flange plates of the first T-shaped steel 3 and the second T-shaped steel 5 are parallel and correspondingly connected by a diagonal brace 4. The Z-shaped structure enables the supporting force of the diagonal brace 4 to directly act on the first T-shaped steel 3 and the second T-shaped steel 5, making the supporting force of the entire structure more uniform. According to needs, the diagonal brace 4 is set as a square tube, and the two ends of the square tube are respectively correspondingly connected to the corresponding ends of the first T-shaped steel 3 and the second T-shaped steel 5, which not only ensures the structural strength but also facilitates batch processing and manufacturing. In addition, the diagonal braces 4 of two adjacent Z-shaped unit frames are arranged in parallel or one end is relatively arranged. As shown in the attached Figure 1 figure, which is relatively arranged. When the first T-shaped steels 3 and the second T-shaped steels 5 of two adjacent Z-shaped unit frames are correspondingly abutted, the adjacent diagonal braces 4 can also be correspondingly assembled and abutted, improving the supporting strength;

[0019] The flange widths of the first T-shaped steel 3 and the second T-shaped steel 5 are respectively adapted to the groove widths of the first channel steel 1 and the second channel steel 2, and can be respectively correspondingly slid into the corresponding first channel steel 1 and second channel steel 2. This is not only convenient for inspection and acceptance during pre-assembly production, but also can reduce a certain welding length during on-site construction under the condition of meeting the same strength requirements. Due to the support structure where the flange of the T-shaped steel is clamped and the web of the T-shaped steel abuts against the channel steel, it is not necessary to fully weld between the flange of the T-shaped steel and the two groove walls of the channel steel. Welding can be carried out at intervals, improving efficiency;

[0020] A plurality of flat braces 6 arranged at intervals along the length direction of the side truss are clamped between the two first channel steels 1 and the two second channel steels 2, serving as the pedal and the top plate frame. According to needs, the flat brace 6 is set as a third T-shaped steel. The two end flange plates of the third T-shaped steel respectively extend outwards above the corresponding first channel steel 1 or second channel steel 2, which is convenient for clamping between the corresponding two channel steels, and is also convenient for L-shaped welding connection of the end flange plate and the web of the T-shaped steel to the channel steel, increasing the connection strength. In addition, the upper surface of the flange of the first T-shaped steel 3 is higher than the top surface of the groove wall of the first channel steel 1. The end flange plates of the third T-shaped steel between the two first channel steels are correspondingly located on the upper surface of the flange of the corresponding first T-shaped steel 1, ensuring that when welding, the first channel steel 1, the third T-shaped steel, and the first T-shaped steel 3 can be welded to each other, and the positioning connection is firm.

[0021] When implementing the pre-assembled structure of the steel structure connecting corridor described in the present utility model, during production, the Z-shaped unit frame and the flat brace 6 can be processed and produced separately, which is very convenient. Then, in combination with the first channel steel 1 and the two second channel steels 2, pre-assembly inspection and acceptance are carried out. After the acceptance is completed, it is disassembled and transported to the site for assembly. The assembled structure itself is a stable structural form. Only according to the overall structural form, welding is carried out at the selected necessary welding positions. Among them, welding at both ends of the flat brace 6 and welding at the interval distance on both sides of the T-shaped steel wing plate are generally necessary.
