Description

Technical Field

[0001] This utility model relates to the field of steel structure factory building technology, specifically to a quick connection device for multi-story steel structure factory buildings. Background Technology

[0002] Multi-story steel structure factory buildings refer to multi-story industrial buildings that use steel as the main load-bearing components. They are typically two or more stories high and feature high space utilization, short construction period, and good seismic performance. The main structure consists of steel columns, steel beams, support systems, and floor slabs. Most components are prefabricated in factories and assembled on-site, using bolts, rivets, and welding during the assembly process.

[0003] For example, a device for quick connection of steel structure components, with application number CN202310313909.1 and authorization announcement date of 20230704, includes a steel column and a shrinkage assembly. A fixing sleeve is fixedly connected to the steel column, and a connecting box is fixedly connected to all four sides of the fixing sleeve. A limiter is installed on the connecting box, and a connecting sleeve is connected to the limiter. A steel beam is fitted inside the connecting sleeve. The shrinkage assembly for shrinking the connecting sleeve is installed inside the connecting box, and the shrinkage assembly includes a coil rotatably installed inside the connecting box. A steel wire is wound on the coil and extends to the outside of the connecting box and is fixedly connected to the connecting sleeve. This device for quick connection of steel structure components, by setting up a shrinkage assembly and a fixing assembly, can pull the offset steel beam to move by tightening a nut and then automatically fix the steel beam after alignment. Therefore, it solves the problem in the prior art that it is time-consuming and labor-intensive to tighten multiple sets of fixing bolts one by one when connecting the steel beam to the steel column.

[0004] Traditional steel structure workshops mainly use welding or bolt fixing methods for connection, which has problems such as low construction efficiency, difficult disassembly, and difficulty in adapting to multi-angle connection requirements. In the existing technology, H-beams are quickly clamped by L-shaped plates and fixing components, but lack three-dimensional adjustment capability. I-beams are quickly connected by toothed web interlocking and C-shaped slots, but have insufficient rotational freedom. Therefore, there is an urgent need to design a quick connection device for multi-story steel structure workshops to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a quick connection device for multi-story steel structure factory buildings to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick connection device for a multi-story steel structure factory building includes a lower limit component and an upper limit component, which are installed together. The lower limit component includes a lower mounting base, and an insertion groove is provided on one outer wall of the lower mounting base. A connecting base is installed on the top outer wall of the lower mounting base through a bearing.

[0008] The upper limit component includes an upper mounting base. The upper mounting base has a second insertion groove on one side of its top outer wall, and a mounting groove is formed on one side of the bottom inner wall of the second insertion groove. One end of the connecting base is mounted inside the mounting groove via a bearing.

[0009] Furthermore, a slot is provided on the outer wall of one side of the top of the lower mounting base, and through holes are provided on both sides of the inner wall of the slot.

[0010] Furthermore, a sliding seat is slidably inserted inside the card slot, and the top two outer walls of the sliding seat are integrally formed with a limit block.

[0011] Furthermore, an adjusting screw is installed inside the slot through a bearing, and a handle is installed at the output end of the adjusting screw through a flat key.

[0012] Furthermore, a slot 2 is provided on the outer wall of one side of the top of the upper mounting base, and through holes 2 are provided on both sides of the inner wall of the slot 2.

[0013] Furthermore, a mounting groove is provided at the bottom of the inner wall of the second slot, and an adjusting screw is installed at the center of the bottom of the mounting groove via a bearing. One end of the adjusting screw is fitted with a handle via a flat key.

[0014] Furthermore, a sliding seat two is slidably connected inside the mounting groove, and the top of the sliding seat two is located inside the slot two.

[0015] Furthermore, two limiting blocks are integrally formed on one side of the outer wall of the sliding seat two, and the sliding seat two is threadedly connected to the adjusting screw two.

[0016] In the above technical solution, the quick connection device for multi-story steel structure workshops provided by this utility model has the following advantages:

[0017] (1) This utility model can achieve 360° rotation adjustment of the column and the beam by means of the bearing matching structure of the connecting seat, the upper mounting seat and the lower mounting seat. It overcomes the limitation that the traditional H-beam connecting device can only be fixed in one direction, solves the problem that the toothed web interlocking structure of the I-beam cannot adapt to non-orthogonal connection, and the rotating structure allows a single node to connect beams at different angles at the same time, which is conducive to reducing the types of connecting parts and reducing the connection cost.

[0018] (2) By rotating handle one and handle two, the adjustment screw one and adjustment screw two can be rotated, thereby driving sliding seat one and sliding seat two to slide inside slot one and slot two, so that the depth of slot one and slot two can be changed, thus adapting to the installation requirements of crossbeams of different specifications.

[0019] (3) The present invention can quickly position the installation of the crossbeam through the limiting block one and the limiting block two. Furthermore, the design of the slot one, slot two and the plug slot one and plug slot two facilitates the rapid positioning of the column and the I-beam, which can improve the efficiency of steel structure workshop assembly.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-8 As shown, the present invention provides a quick connection device for a multi-story steel structure factory building, including a lower limit member 1 and an upper limit member 2. The lower limit member 1 and the upper limit member 2 are installed together. The lower limit member 1 includes a lower mounting base 3. A plug-in groove 11 is provided on one side of the outer wall of the lower mounting base 3. A connecting seat 8 is installed on one side of the top outer wall of the lower mounting base 3 through a bearing.

[0033] The upper limit component 2 includes an upper mounting base 12. The upper mounting base 12 has a second insertion groove 17 on one side of the top outer wall, and a mounting groove 18 is provided on one side of the bottom inner wall of the second insertion groove 17. One end of the connecting base 8 is installed inside the mounting groove 18 through a bearing.

[0034] Specifically, in this embodiment, a lower limit member 1 and an upper limit member 2 are included. The lower limit member 1 and the upper limit member 2 are installed together. The lower limit member 1 includes a lower mounting base 3. A insertion groove 11 is provided on one side of the outer wall of the lower mounting base 3. The insertion groove 11 facilitates the installation of the column and the lower mounting base 3 together. A connecting seat 8 is installed on one side of the top of the lower mounting base 3 through a bearing. The connecting seat 8 facilitates the installation of the upper limit member 2 and the lower limit member 1 together.

[0035] The upper limit component 2 includes an upper mounting base 12. The upper mounting base 12 has a second insertion groove 17 on one side of its top outer wall. The second insertion groove 17 facilitates the installation of the upper mounting base 12 with the column installed above. The second insertion groove 17 also has an installation groove 18 on one side of its inner bottom. The installation groove 18 facilitates the installation of the upper mounting base 12 with the connecting seat 8. One end of the connecting seat 8 is installed inside the installation groove 18 via a bearing. When it is necessary to install structures such as crossbeams, the upper mounting base 12 can be rotated according to the installation requirements, so that the upper mounting base 12 and the connecting seat 8 can rotate around the lower mounting base 3, thereby changing the angle of the upper mounting base 12 to meet the installation requirements of crossbeams in different positions.

[0036] This utility model provides a quick connection device for multi-story steel structure workshops. Through the bearing cooperation structure of the connecting seat 8 with the upper mounting seat 12 and the lower mounting seat 3, the column and the beam can be rotated and adjusted 360°. This overcomes the limitation of traditional H-beam connection devices that can only be fixed in one direction. It also solves the problem that the toothed web interlocking structure of I-beams cannot adapt to non-orthogonal connections. Furthermore, this rotating structure allows a single node to connect beams at different angles at the same time, which helps to reduce the types of connecting parts and lower the connection cost.

[0037] In one embodiment provided by this utility model, such as Figure 2-4 As shown, a slot 4 is provided on the outer wall of one side of the top of the lower mounting base 3, and through holes 5 are provided on both sides of the inner wall of the slot 4. The through holes 5 facilitate the insertion of bolts into the slot 4 and facilitate the fixing of the crossbeam inside the slot 4. A sliding seat 6 is slidably inserted inside the slot 4, and the outer walls of the top two sides of the sliding seat 6 are integrally formed with limit blocks 7. An adjusting screw 9 is installed inside the slot 4 through a bearing, and a handle 10 is installed at the output end of the adjusting screw 9 through a flat key. When the handle 10 is rotated, the handle 10 drives the adjusting screw 9, which in turn causes the sliding seat 6 to move linearly within the slot 4, thereby changing the depth inside the slot 4.

[0038] In another embodiment provided by this utility model, such as Figure 5-8As shown, a slot 13 is provided on one side of the outer wall of the top of the upper mounting base 12, and through holes 16 are provided on both sides of the inner wall of the slot 13. The through holes 16 facilitate the insertion of bolts into the slot 13 and the fixing of the crossbeam inside the slot 13. A mounting groove 19 is provided at the bottom of the inner wall of the slot 13, and an adjusting screw 20 is installed at the center of the bottom of the inner wall of the mounting groove 19 via a bearing. A handle 21 is installed at one end of the adjusting screw 20 via a flat key. A sliding seat 14 is slidably connected inside the mounting groove 19. By rotating the handle 21, the hand... Handle 21 rotates with adjusting screw 20, which drives sliding seat 24 to move. Sliding seat 24 moves inside slot 23, changing the depth inside slot 23. The top of sliding seat 24 is located inside slot 23. Two limiting blocks 25 are integrally formed on one side of the outer wall of sliding seat 24. When the crossbeam is installed inside slot 23, the design of limiting blocks 215 facilitates the quick positioning of the crossbeam inside slot 23. Sliding seat 214 and adjusting screw 20 are threadedly connected.

[0039] Working principle: When using this device, the lower mounting base 3 can be installed on the column through the insertion slot 11. Then, the handle 10 is rotated, which drives the adjusting screw 9. The adjusting screw 9 will cause the sliding seat 6 to move linearly in the slot 4, changing the depth inside the slot 4. Subsequently, the handle 21 is rotated, which will rotate the adjusting screw 20. The adjusting screw 20 will drive the sliding seat 14 to move, and the sliding seat 14 will move inside the slot 13, changing the depth inside the slot 13. When it is necessary to install crossbeams or other structures, the upper mounting base 12 can be rotated according to the installation requirements, so that the upper mounting base 12 and the connecting seat 8 can rotate around the lower mounting base 3, changing the angle of the upper mounting base 12 to meet the needs of crossbeam installation in different positions. When the crossbeam is installed inside the slot 4 or the slot 13, the design of the limiting block 7 and the limiting block 15 facilitates the quick positioning of the crossbeam inside the slot 4 or the slot 13.

[0040] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
