Description

Technical Field

[0001] This utility model relates to the field of building steel technology, and in particular to a corrosion-resistant building steel structure connection node. Background Technology

[0002] The connection nodes of corrosion-resistant building steel structures mainly adopt rigid connection methods, and the common forms include welding and bolting. These nodes are usually composed of steel plates, steel pipes, bolts or welded parts, and undergo surface anti-corrosion treatment (such as hot-dip galvanizing, spraying anti-corrosion coating, etc.) to improve corrosion resistance.

[0003] However, traditional connection nodes are mostly rigid connections. When subjected to external impacts or overloads, they cannot effectively absorb impact energy, which can easily lead to structural vibration or damage. Furthermore, the tensile force is applied to the fasteners (bolts, screws, nuts, etc.) used in the connection, causing damage to the fasteners and shortening their service life.

[0004] Therefore, those skilled in the art have provided a corrosion-resistant steel structure connection node to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrosion-resistant steel structure connection node. This node is equipped with a positioning mechanism. By rotating the positioning nut, the elastic force of the spring can be adjusted, thereby adjusting the force connecting the horizontal column and the support column. This allows the elastic element to provide buffering when the horizontal column is subjected to excessive tension, absorbing some impact energy, reducing instantaneous stress on the structure, improving the overall seismic and wind resistance, and reducing tensile damage to the fixing screws. When the horizontal column is overloaded, it will move outward, and after the elastic element returns to its original position, metal fatigue or breakage is avoided, thus extending the service life of the connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A corrosion-resistant steel structure connection node includes a support column. A connection mechanism is provided in the middle of the outer wall of the support column. The connection mechanism includes a connection seat. Multiple mounting slots are provided on the outer walls around the connection seat. A connection block is engaged with the outer walls around the connection seat. A reinforcing plate is fixedly connected to the outer wall of the connection block near the connection seat. Multiple mounting blocks are fixedly connected to the outer wall of the reinforcing plate near the connection seat.

[0008] The connecting mechanism is equipped with positioning mechanisms on all four sides. Each positioning mechanism includes a positioning slot and a mounting plate. Limiting blocks are fixedly connected to the rear ends of the inner walls on both sides of the positioning slot. A positioning groove is formed at the center of the outer wall of the front end of the limiting block. An elastic element is provided in the middle of the inner wall of the positioning groove. A positioning slider is slidably connected to the rear end of the inner wall of the positioning groove. A positioning screw is fixedly connected to the center of the outer wall of the front end of the positioning slider. A positioning nut is threaded onto the front end of the outer wall of the positioning screw. A horizontal column is provided at the end of the positioning mechanism away from the connecting mechanism.

[0009] Through the above technical solution, the node is equipped with a connection mechanism, which connects the components through snap-fit ​​limiting and threaded fixing. This allows users to disassemble and replace the connection blocks that have become too long or damaged as needed, thereby reducing the trouble of maintaining the node and extending its service life.

[0010] Furthermore, the connecting seat is fixedly connected to the middle part of the outer wall of the support column;

[0011] The above technical solution enables the horizontal column to be snapped and fixed around the support column.

[0012] Furthermore, the mounting block engages with the mounting slot.

[0013] The above technical solution enables the connecting block to be snapped onto the connecting seat.

[0014] Furthermore, a limiting screw is fixedly connected at the center of the bottom surface of the mounting slot, and a locking nut is threaded onto the upper end of the outer wall of the limiting screw;

[0015] The above technical solution enables the limiting screw to perform secondary limiting on the mounting block, and then locks it in place using a locking nut.

[0016] Furthermore, the positioning slot is located in the middle of the outer wall of the connecting block on the side away from the reinforcing plate;

[0017] The above technical solution enables the horizontal column to be snapped and positioned on the connecting block.

[0018] Furthermore, the mounting plates are fixedly connected to both sides of the front and rear outer walls of the cross column, and the inner wall of the rear end of the positioning slot is tightly fitted with a rubber pad.

[0019] Through the above technical solution, the rubber pad can buffer and absorb the force generated by the horizontal column resetting, and the horizontal column can be fixed to the connecting block by the mounting plate bolts.

[0020] Furthermore, the elastic element is sleeved in the middle of the outer wall of the positioning screw;

[0021] The above technical solution enables pressure to be applied to the elastic element when the position of the positioning screw moves.

[0022] Furthermore, the positioning screw is slidably connected to the limiting block;

[0023] The above technical solution enables users to adjust the position of the positioning screw by rotating the positioning nut.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a corrosion-resistant steel structure connection node. Compared with most traditional corrosion-resistant steel structure connection nodes, this node is equipped with a positioning mechanism. By rotating the positioning nut, the elastic force of the spring can be adjusted, thereby adjusting the force between the horizontal column and the support column. This allows the elastic element to provide buffer when the horizontal column is subjected to excessive tension, absorbing some impact energy, reducing instantaneous stress on the structure, helping to improve the overall seismic and wind resistance, and reducing tensile damage to the fixing screws. When the horizontal column is overloaded, it will move outward, and after the elastic element returns to its original position, it avoids metal fatigue or breakage, thereby extending the service life of the connection part.

[0026] 2. The corrosion-resistant steel structure connection node proposed in this utility model is different from most traditional corrosion-resistant steel structure connection nodes. This node is equipped with a connection mechanism and is connected by snap-fit ​​limiting and threaded fixing. This allows users to disassemble and replace the connection blocks that have been used for too long or damaged as needed, so as to reduce the trouble of maintenance and extend the service life of the node.

A corrosion-resistant building steel structure connection node, including a support column 1, a connection mechanism 2 is provided in the middle of the outer wall of the support column 1, the connection mechanism 2 includes a connection seat 201, a plurality of mounting slots 202 are provided on the outer wall around the connection seat 201, a connection block 205 is engaged with the outer wall around the connection seat 201, a reinforcing plate 206 is fixedly connected to the outer wall of the connection block 205 near the connection seat 201, and a plurality of mounting blocks 207 are fixedly connected to the outer wall of the reinforcing plate 206 near the connection seat 201.

[0040] Positioning mechanisms 3 are provided around the connecting mechanism 2. The positioning mechanism 3 includes a positioning slot 301 and a mounting plate 308. Limiting blocks 303 are fixedly connected to the rear ends of the inner walls on both sides of the positioning slot 301. A positioning slide groove 304 is provided at the center of the outer wall of the front end of the limiting block 303. An elastic element 305 is provided in the middle of the inner wall of the positioning slide groove 304. A positioning slider 306 is slidably connected to the rear end of the inner wall of the positioning slide groove 304. A positioning screw 307 is fixedly connected to the center of the outer wall of the front end of the positioning slider 306. A positioning nut 309 is threadedly engaged at the front end of the outer wall of the positioning screw 307. A horizontal column 4 is provided at the end of the positioning mechanism 3 away from the connecting mechanism 2. The node is provided with the connecting mechanism 2 and is connected by a snap-fit ​​limiting and threaded fixing method. This allows the user to disassemble and replace the connecting block 205 that is too long or damaged as needed, so as to reduce the trouble of maintenance of the node and extend the service life of the node.

[0041] Reference Figure 2 , 3 The connecting seat 201 is fixedly connected to the middle of the outer wall of the support column 1, so that the horizontal column 4 can be snapped and fixed around the support column 1. The mounting block 207 is engaged with the mounting slot 202, so that the connecting block 205 can be snapped and installed on the connecting seat 201. The center of the bottom surface of the mounting slot 202 is fixedly connected to the limiting screw 203. The upper end of the outer wall of the limiting screw 203 is threaded with a locking nut 204, so that the limiting screw 203 can perform secondary limiting on the mounting block 207 and lock it in place by the locking nut 204.

[0042] Reference Figure 4 , 5 The positioning slot 301 is located in the middle of the outer wall of the connecting block 205 away from the reinforcing plate 206, so that the cross column 4 can be locked and limited on the connecting block 205. The mounting plate 308 is fixedly connected to the two sides of the outer wall of the front and rear ends of the cross column 4 respectively. The inner wall of the rear end of the positioning slot 301 is tightly fitted with a rubber pad 302, so that the rubber pad 302 can buffer and absorb the force generated by the resetting of the cross column 4. The cross column 4 can be fixed to the connecting block 205 by bolts of the mounting plate 308. The elastic element 305 is sleeved in the middle of the outer wall of the positioning screw 307, so that when the position of the positioning screw 307 moves, pressure can be applied to the elastic element 305. The positioning screw 307 is slidably connected to the limiting block 303, so that the user can adjust the position of the positioning screw 307 by rotating the positioning nut 309.

[0043] Working principle: Select an appropriate number of connecting blocks 205 according to the installation requirements and install them on the connecting seat 201. Rotate the multiple positioning nuts 309 at both ends of the cross column 4 to adjust the connection of the elastic element 305. When the support column 1 on one side of the cross column 4 is slightly offset, the cross column 4 is offset to a certain extent, thereby applying pressure to the elastic element 305 at both ends by pulling the fixing parts (positioning screw 307 and positioning nut 309). The elastic element 305 absorbs and buffers the force, and then resets the position between the support column 1 and the cross column 4, reducing the damage to the fixing parts (positioning screw 307 and positioning nut 309) caused by the tension.
