Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, and in particular relates to a steel frame beam-column joint. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Steel frame connection nodes are an important part of steel structures, responsible for transferring and distributing loads to ensure the overall stability and safety of the structure.

[0003] Temporary steel frames are widely used in various fields such as construction, bridges, stages, and emergency response. However, existing steel frame beam-column joints are generally fixed using welding or bolts, which presents several problems: First, although some structures incorporate positioning mechanisms, these mechanisms still require aligning the steel columns and beams before fixing, making assembly and fixing inconvenient and reducing construction efficiency. Second, disassembly is difficult, presenting drawbacks. Third, while elastic structures are used for energy dissipation or self-resetting, their function is limited and they are not integrated with the positioning mechanisms, thus hindering construction efficiency and overall structural performance. Fourth, high installation precision requirements (such as preload adjustment and alignment) increase construction difficulty, and structural complexity increases maintenance costs. Furthermore, sliding, rotating, or friction components (such as those with elongated holes) are prone to wear, leading to decreased positioning accuracy or loose connections. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel frame beam-column joint. By using a positioning mechanism to position the beam-column joint laterally and vertically, and combining it with an elastic structure, the beam-column connection process is automatically positioned and self-reset and clamped, improving construction efficiency while enhancing structural performance.

[0005] A steel frame beam-column joint includes a steel column and a steel beam, with positioning piles wrapped around the outside of the steel column, and the steel beam positioned by a positioning mechanism and bolted around the positioning piles;

[0006] The positioning mechanism includes a top-tightening cover plate set on the top of the positioning pile. When the steel beam is connected to the positioning pile, the top-tightening cover plate is lifted by the elastic element at its bottom and self-reset after the steel beam is connected to the positioning pile. The top-tightening cover plate is bolted to the top of the steel beam.

[0007] The positioning mechanism also includes a lateral positioning connection mechanism and a vertical positioning locking mechanism between the steel beam and the positioning pile. The locking direction of the vertical positioning locking mechanism is consistent with the direction of elastic potential energy release of the elastic element.

[0008] The top cover plate is provided with multiple sets of connecting lugs around its perimeter for bolt connection with the steel beam.

[0009] The elastic element includes a spring, which is arranged along the height direction of the steel column; the spring does not deform in its initial state.

[0010] Multiple connecting rods are provided on the side of the top-tightening cover plate facing the positioning pile. Multiple sets of mounting holes are opened on the side of the positioning pile facing the top-tightening cover plate opposite to the connecting rods. The connecting rods can be movably inserted into the mounting holes. One end of the spring is connected to the bottom of the mounting hole, and the other end is connected to the connecting rod.

[0011] The lateral positioning connection mechanism includes a positioning connection block installed at one end of the steel beam that is connected to the positioning pile. The side of the positioning pile that is connected to the steel beam has a positioning connection groove corresponding to the positioning connection block. The positioning connection block is laterally bolted to the positioning connection groove.

[0012] The positioning connecting block and the positioning connecting groove have multiple sets of transverse screw holes corresponding to each other, and the positioning connecting block and the positioning connecting groove are connected by bolts.

[0013] The vertical positioning and locking mechanism includes a positioning locking block fixedly installed at the bottom of the positioning connecting block. The positioning pile has multiple positioning locking slots that correspond one-to-one with the position and number of the positioning locking blocks. The positioning locking blocks are inserted into the positioning locking slots along the height direction of the steel column to realize the vertical positioning and connection of the beam and column.

[0014] The positioning connecting block has screw holes for connecting and fixing to the top cover plate.

[0015] Multiple sets of stiffening ribs are fixedly installed on the lower side of the positioning pile to support the positioning pile and steel beam upward.

[0016] The top cover plate has multiple sets of gripping grooves on its upper side.

[0017] By employing the above technical solution, this utility model application has at least the following beneficial effects:

[0018] This utility model, through the setting of positioning piles, positioning connecting blocks, positioning connecting grooves, positioning snap-fit ​​grooves, positioning snap-fit ​​blocks, connecting ear plates, and the mutual cooperation of various structures, enables convenient positioning and connection of steel columns and steel beams, improves the ease of assembly of steel columns and steel beams, reduces labor intensity, and increases work efficiency.

[0019] This utility model achieves beam-column connection through bolt connection, which makes it easy to assemble and fix steel columns and steel beams, and also facilitates disassembly later, improving disassembly convenience and allowing for repeated use.

[0020] The deformation direction of the elastic component of this invention is consistent with the snap-fit ​​movement direction of the snap-fit ​​groove and snap-fit ​​block, which reduces the complexity of operation, improves the assembly efficiency, avoids stress concentration caused by misalignment, extends the life of the elastic component, and reduces friction loss.

[0028] To better explain and facilitate understanding of this utility model, the technical solution and effects of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Combination Figures 1-5 As shown, a steel frame beam-column joint includes a steel column 1 and a steel beam 3. Positioning piles 2 are installed around the outside of the steel column 1, and the steel beam 3 is positioned around the positioning piles 2 by a positioning mechanism.

[0030] In this embodiment, the positioning pile 2 is a positioning frame installed on the outside of the steel column 1, wrapped around the outside of the steel column 1, and connected by a third bolt 18. The positioning pile 2 and the steel column 1 have corresponding third screw holes 19. The positioning pile 2 and the steel column 1 are fixed by the third bolt 18, and can also be quickly disassembled later.

[0031] The positioning mechanism includes a top-tightening cover plate 10 disposed on the top of the positioning pile 2. Multiple sets of connecting lugs 11 are arranged around the top-tightening cover plate 10 for connection with the steel beam 3. In this embodiment, four sets of connecting lugs 11 are arranged around the top-tightening cover plate 10, and the connection with the steel beam 3 is achieved through second bolts 12. Multiple connecting rods 16 are arranged on the side of the top-tightening cover plate 10 facing the positioning pile 2. Multiple sets of mounting holes 14 are opened on the side of the positioning pile 2 facing the top-tightening cover plate 10 opposite to the connecting rods 16. The connecting rods 16 can be movably inserted into the mounting holes 14, and the connecting rods 16 can play a limiting and guiding role during the upward movement and downward tightening of the top-tightening cover plate 10. In this embodiment, four connecting rods 16 are located at the four corners of the top-tightening cover plate 10, and four mounting holes 14 are correspondingly opened on the positioning pile 2.

[0032] Furthermore, to improve construction efficiency and enhance the overall performance of the structure, a spring 15 is installed inside the mounting hole 14. The spring 15 is positioned along the height of the steel column 1, with one end connected to the bottom of the mounting hole 14 and the other end connected to the connecting rod 16. The spring 15 does not deform in its initial state.

[0033] During construction, when the steel beam 3 is connected to the positioning pile 2, the insertion action of the steel beam 3 towards the positioning pile 2 will push the top cover plate 10 upward, thereby pushing the top cover plate 10 upward, and the spring 15 will deform and elongate; after the steel beam 3 is connected to the positioning pile 2, the top cover plate 10 moves downward under the action of the spring 15, the elastic potential energy is released, and the top cover plate 10 quickly self-resets to its original position, thereby enabling the connecting ear plate 11 to quickly fit against the steel beam 3.

[0034] To achieve stable positioning and connection of the beam and column, the positioning mechanism also includes a lateral positioning connection mechanism and a vertical positioning locking mechanism between the steel beam 3 and the positioning pile 2. Specifically, the lateral positioning connection mechanism includes a positioning connecting block 4 at the end of the steel beam 3 connected to the positioning pile 2. The positioning connecting block 4 has a second screw hole 13 for connection and fixation with the connecting lug 11. The side of the positioning pile 2 connected to the steel beam 3 has a positioning connecting groove 5 corresponding to the positioning connecting block 4. The positioning connecting block 4 and the positioning connecting groove 5 have multiple sets of lateral first screw holes 9 corresponding to each other. The lateral positioning and connection between the positioning connecting block 4 and the positioning connecting groove 5, i.e., the lateral positioning and connection between the steel beam 3 and the positioning pile 2, is achieved by the first bolt 8.

[0035] Furthermore, the vertical positioning and locking mechanism includes a positioning locking block 7 fixedly installed at the bottom of the positioning connecting block 4. The positioning pile 2 has multiple positioning locking slots 6 that correspond one-to-one with the position and number of the positioning locking blocks 7. The positioning locking blocks 7 are inserted into the positioning locking slots 6 along the height direction of the steel column 1 to realize the vertical positioning and connection of the beam and column.

[0036] During the connection between the steel beam 3 and the steel column 1, the steel beam 3 is inserted into the positioning stake 2 on the outside of the steel column 1, and the positioning insertion block on the steel beam 3 is inserted into the positioning insertion slot on the positioning stake 2. During the insertion process, the top cover plate 10 is pushed upward, thereby pushing the top cover plate 10 upward. The spring 15 deforms and extends upward along the height direction of the steel column 1. As the positioning insertion block is inserted, the positioning locking block 7 moves downward along the height direction of the steel column 1, inserts and locks into the positioning locking slot 6, thereby achieving the initial positioning of the steel beam 3. At this time, the spring 15 contracts downward to release elastic potential energy, and the top cover plate 10 moves downward under the action of the spring 15. The top cover plate 10 quickly self-resets to its original position, thereby enabling the connecting ear plate 11 to quickly fit against the steel beam 3. Then, the second bolt 12 is screwed into the second screw hole 13, which can quickly position the steel beam 3. Then, by screwing the first bolt 8 into the first screw hole 9, the first bolt 8 extends through the third screw hole 19 on the positioning pile 2 to the inside of the steel column 1, connecting the steel column 1, positioning pile 2, steel beam 3 and positioning block 4 together, thereby ensuring the installation stability of the steel frame, and also enabling quick disassembly later.

[0037] When disassembly is required, it can be achieved by unscrewing the first bolt 8, which is simple and convenient. In this embodiment, the top clamping cover 10 has multiple sets of gripping grooves on its upper side. The gripping grooves can easily pull the top clamping cover 10 upward, so that when the steel frame is disassembled later, the top clamping cover 10 can be pulled upward by the gripping grooves, thereby facilitating the removal of the positioning connecting block 4 from the positioning connecting groove 5 and improving the ease of disassembly.

[0038] To improve structural performance, multiple sets of stiffening ribs 17 are fixedly installed on the lower side of the positioning pile 2 to support the positioning pile 2 and the steel beam 3 upwards, and to support and reinforce the positioning connecting blocks 4 at the ends of the positioning pile 2 and the steel beam 3 to ensure the strength of use.

[0039] The working principle and construction process of the above-mentioned steel frame beam-column joint are as follows:

[0040] First, fix the steel column 1 to the ground. Then, place the positioning stake 2 on the outside of the steel column 1 and fix it with multiple sets of third bolts 18. Next, insert the steel beam 3 into the positioning stake 2. Insert the positioning connecting block 4 at the end of the steel beam 3 into the positioning connecting groove 5 on the outside of the positioning frame 2. At the same time, make the positioning snap-fit ​​block 7 snap into the positioning snap-fit ​​groove 6 from top to bottom. The spring force of the spring 15 drives the ear plate 11 to stick tightly to the positioning block 4. Then, screw the second bolt 12 into the second screw hole 13. The positioning connecting block 4 and the steel beam 3 are quickly positioned by connecting the ear plate 11. Finally, screw the first bolt 8 into the first screw hole 9 to quickly install and fix the steel beam 3.
