Description

Technical Field

[0001] This utility model belongs to the field of steel structure node connection technology, and specifically relates to a connection device for steel structure nodes. 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 steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Connecting devices are required during the installation of steel structures.

[0003] However, when connecting steel structures, threaded bolts are usually inserted into mounting holes and then tightened with nuts. This process typically requires multiple insertions and tightenings, making installation and disassembly time-consuming and labor-intensive, which is not conducive to improving work efficiency. Since steel structure nodes are generally located at high altitudes, disassembly and fastening of the steel structure at heights are difficult. Furthermore, there is a risk of falling when carrying and retrieving parts at heights. This method of installing steel structure node devices that requires carrying parts is not suitable for complex scenarios involving high-altitude operations.

[0004] Therefore, a connection device for steel structure nodes is needed to solve the problem that it is difficult to disassemble, assemble, and fasten steel structure nodes at high altitudes in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a connection device for steel structure nodes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection device for a steel structure node, comprising a first I-beam and a second I-beam, the second I-beam being disposed on one side of the first I-beam, a support slide box being fixed to one side surface of the first I-beam, a support slide groove being formed on the front surface of the support slide box, an assembly mechanism being provided on the surface of the support slide box, the assembly mechanism comprising a support bracket, a support positioning column, an adjusting slider, and a mounting hole, the support bracket being fixed to the front surface of the support slide box, the support positioning column being fixed to the upper end surface of the support bracket, the adjusting slider being slidably connected to the inside of the support slide box, the mounting hole being formed at the bottom of the second I-beam, and reinforcement mechanisms being provided on both sides of the second I-beam.

[0007] It should be noted in the solution that the reinforcement mechanism includes a mounting plate, a telescopic rod, a compression spring, and a guide slider. The mounting plate is fixed to one side surface of the second I-beam, one end of the telescopic rod is fixed to the surface of the mounting plate, the guide slider is fixed to the other end of the telescopic rod, and the compression spring is sleeved on the outside of the telescopic rod.

[0008] It is worth noting that the adjusting slider is slidably connected inside the support groove, the upper surface of the adjusting slider is fixed with an adjusting screw sleeve, a rotating seat is fixed at the center of the inner top wall of the support box, and an adjusting screw rod passes through the inside of the support box.

[0009] Furthermore, it should be noted that the top end of the adjusting screw is rotatably connected to the inside of the rotating seat, the adjusting screw is threadedly connected to the adjusting screw sleeve, and an adjusting handwheel is fixed to one end of the adjusting screw that protrudes from the supporting slide box.

[0010] In a preferred embodiment, the bottom of the second I-beam is provided with a mounting hole, the mounting hole on the support positioning column and the second I-beam are engaged and matched, the bottom surface of the mounting protrusion is in contact with the bottom surface of the support bracket, and the bottom of the first I-beam is fixed with a mounting base.

[0011] In a preferred embodiment, a positioning groove is provided at the lower edge of the inner sidewall of the support bracket, and the guide slider engages and matches with the positioning groove.

[0012] Compared with the prior art, the connection device for steel structure nodes provided by this utility model has at least the following beneficial effects:

[0013] (1) Through the assembly mechanism, the adjusting sleeve connected to the adjusting screw thread can drive the adjusting slider to slide down along the support slide groove. This can adjust the distance between the support bracket and the adjusting slider, which can adapt to the connection of steel structures of different heights. In addition, the cooperation between the support bracket and the support positioning column can realize the quick connection with the second I-beam node, thus eliminating the need for fasteners such as screws, which helps to reduce the safety hazards of disassembling and assembling steel structures at high altitudes.

[0014] (2) Through the reinforcement mechanism, the guide slider can regain its elasticity by the rebound force of the compression spring, which can lock the guide slider inside the positioning groove. This re-fixing method can not only strengthen the stability of the steel structure at the node connection, but also save the trouble of workers having to fix it with bolts again during high-altitude installation.

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please see Figure 1-4 This utility model provides a connection device for a steel structure node, including a first I-beam 1 and a second I-beam 2. The second I-beam 2 is disposed on one side of the first I-beam 1. A support slide box 3 is fixed to one side surface of the first I-beam 1. A support slide groove 4 is opened on the front surface of the support slide box 3. An assembly mechanism is provided on the surface of the support slide box 3. The assembly mechanism includes a support bracket 5, a support positioning column 6, an adjusting slider 8, and a mounting hole 17. The support bracket 5 is fixed to the front surface of the support slide box 3. The support positioning column 6 is fixed to the upper end surface of the support bracket 5. The adjusting slider 8 is slidably connected to the inside of the support slide box 3. The mounting hole 17 is opened at the bottom of the second I-beam 2. Reinforcing mechanisms are provided on both sides of the second I-beam 2.

[0022] Further as Figure 1 and Figure 4 As shown, it is worth noting that the reinforcement mechanism includes a mounting plate 12, a telescopic rod 13, a compression spring 14, and a guide slider 15. The mounting plate 12 is fixed to one side surface of the second I-beam 2, one end of the telescopic rod 13 is fixed to the surface of the mounting plate 12, the guide slider 15 is fixed to the other end of the telescopic rod 13, and the compression spring 14 is sleeved on the outside of the telescopic rod 13.

[0023] Further as Figure 3 As shown, it is worth noting that the adjusting slider 8 is slidably connected inside the support slide groove 4, the upper surface of the adjusting slider 8 is fixed with an adjusting screw sleeve 11, the center of the inner top wall of the support slide box 3 is fixed with a rotating seat 9, and the inside of the support slide box 3 is provided with an adjusting screw rod 7.

[0024] This solution has the following working process: During use, the lifting device lifts the second I-beam 2 and places it on the support bracket 5. The support positioning column 6 on the support bracket 5 corresponds to the mounting hole 17 on the second I-beam 2. Then, the adjusting handwheel 10 can be rotated to drive the adjusting screw 7 to rotate at the rotating seat 9 in the support slide box 3. At this time, the adjusting sleeve 11, which is threaded to the adjusting screw 7, can drive the adjusting slider 8 to slide down along the support slide groove 4. This can adjust the distance between the support bracket 5 and the adjusting slider 8, which can adapt to the connection of steel structures of different heights. In addition, the cooperation between the support bracket 5 and the support positioning column 6 can realize the quick connection at the node of the second I-beam 2, thereby eliminating the need for fasteners such as screws, which helps to reduce the safety hazards of disassembling and assembling steel structures at high altitudes.

[0025] As can be seen from the above working process, the adjusting sleeve 11 connected to the adjusting screw 7 can drive the adjusting slider 8 to slide down along the support groove 4, thus adjusting the distance between the support bracket 5 and the adjusting slider 8, which can adapt to the connection of steel structures at different heights. In addition, the cooperation between the support bracket 5 and the support positioning column 6 can realize the quick connection at the node of the second I-beam 2, thereby eliminating the need for fasteners such as screws, which helps to reduce the safety hazards of assembling and disassembling steel structures at high altitudes.

[0026] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the top end of the adjusting screw 7 is rotatably connected inside the rotating seat 9, the adjusting screw 7 is threadedly connected to the adjusting sleeve 11, and the end of the adjusting screw 7 that passes through the support slide box 3 is fixed with the adjusting handwheel 10.

[0027] Further as Figure 4 As shown, it is worth noting that the bottom of the second I-beam 2 has a mounting hole 17. The support positioning column 6 and the mounting hole 17 on the second I-beam 2 are engaged and matched. The bottom surface of the mounting protrusion 12 is in contact with the bottom surface of the support bracket 5. The bottom of the first I-beam 1 is fixed with a mounting base. During the reinforcement of the node of the second I-beam 2, the guide slider 15 compresses the compression spring 14. When the compression spring 14 is in a compressed state, when the guide slider 15 slides into the inside of the positioning groove 16, the guide slider 15 recovers its elasticity again through the rebound force of the compression spring 14, which can engage the guide slider 15 inside the positioning groove 16. This method of re-fixing not only strengthens the stability of the steel structure at the node connection, but also saves the trouble of workers having to fix it with bolts again during high-altitude installation.

[0028] Further as Figure 1 As shown, it is worth noting that a positioning groove 16 is provided at the lower edge of the inner side wall of the support bracket 5, and the guide slider 15 engages and matches with the positioning groove 16.

[0029] In summary: The adjusting sleeve 11 connected to the adjusting screw 7 can drive the adjusting slider 8 to slide downward along the support groove 4, thus adjusting the distance between the support bracket 5 and the adjusting slider 8. This can adapt to steel structure connections of different heights. Furthermore, the cooperation between the support bracket 5 and the support positioning column 6 can achieve a quick connection at the node of the second I-beam 2, thereby eliminating the need for fasteners such as screws and reducing the safety hazards of disassembling and assembling steel structures at heights. The guide slider 15 can regain its elasticity through the rebound force of the compression spring 14, which can lock the guide slider 15 inside the positioning groove 16. This re-fixing method not only strengthens the stability of the steel structure at the node connection but also saves the trouble of workers having to fix it with bolts again during high-altitude installation.
