Description

Technical Field

[0001] The utility model relates to the technical field of supporting trusses, in particular to a prefabricated steel structure supporting truss. Background Art

[0002] A support truss is a structure made of rods connected to each other by hinges at both ends. The truss is a plane or space structure composed of straight rods and generally has triangular units. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams. Most support trusses are welded, which is not easy to disassemble and install.

[0003] A Chinese patent document with publication number CN216379967U discloses a prefabricated steel structure support truss, including a vertical rod, a connecting block fixed on one side of the vertical rod, a fixing groove provided on one side of the connecting block, a cross bar inserted in the fixing groove, cavities provided at both upper and lower ends of the fixing groove, a clamping groove provided at both upper and lower ends of the cross bar, a clamping rod movable and engaged in the clamping groove provided in the cavity, and a rotating disk rotatably driven to move the clamping rod provided on the outer side of the connecting block. By rotating the rotating disk, the clamping rod can be moved to facilitate clamping and splicing of the cross bar, and also facilitates the movement away from the restriction on the cross bar.

[0004] The disadvantages of the above disclosed solution are that the structure connecting the horizontal bar and the vertical bar is complicated. When disassembling, firstly, the locking block releases the restriction on the gear, and then the turntable is rotated to drive the clamping rod out of the slot. When installing, firstly, the turntable is rotated to drive the clamping rod into the slot, and then the locking block is locked to the gear. As a result, the whole process of disassembling or installing the horizontal bar and the vertical bar is cumbersome, with many operation steps, time-consuming and labor-intensive, and reducing the efficiency of disassembling and installing the truss. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a prefabricated steel structure support truss with a simple structure and simple assembly and disassembly steps, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prefabricated steel structure support truss, comprising a column, on which a cross bar is detachably connected; a connecting block is fixedly arranged on the column, a guide groove is provided on the connecting block, one end of the cross bar is inserted into the guide groove, a slot is provided on the part of the cross bar inserted into the guide groove, a slide groove connected to the guide groove is provided on the connecting block, a pin is slidably arranged in the slide groove, one end of the pin extends to the outside of the connecting block, and the other end of the pin is plugged into the slot, a gasket is fixedly sleeved on the pin, and a spring is fixedly arranged between the gasket and the slide groove.

[0007] Furthermore, there are two slide grooves, which are symmetrically arranged on the connecting block.

[0008] Furthermore, one end of the plug pin that is plugged into the slot is an inclined surface, and the inclined surface at one end of the plug pin is slidably matched with the cross bar.

[0009] Furthermore, a circular plate is fixedly provided at one end of the latch located outside the connecting block.

[0010] Furthermore, the guide groove in the connecting block is adapted to the shape of the cross bar.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Since a latch is slidably arranged in the slide slot, the other end of the latch is plugged into the slot, a gasket is fixedly sleeved on the latch, and a spring is fixedly arranged between the gasket and the slide slot. Therefore, during installation, the latch moves upward and compresses the spring during the process of the crossbar being inserted into the guide slot of the connecting block. When the crossbar drives the slot to align with the slide slot, the latch is inserted into the slot under the action of the reset force of the spring, thereby restricting the crossbar, and the splicing of the column and the crossbar can be completed. During disassembly, the latch is pulled outward to disengage the latch from the slot, and the crossbar can be pulled outward from the guide slot of the connecting block, and the disassembly of the column and the crossbar can be completed. The connection structure is simple, and the operation steps of disassembling or installing the column and the crossbar are simple, which saves time and effort, and improves the efficiency of disassembling and installing the column and the crossbar.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a prefabricated steel structure support truss, comprising a column 1, on which a crossbar 2 is detachably connected. A connection block 3 is fixedly welded to one side of the column 1, and a guide groove is provided inside the connection block 3, which is perpendicular to the column 1. One end of the crossbar 2 is slidably inserted into the guide groove, and the guide groove is adapted to the shape of the crossbar 2.

[0019] The portion of the crossbar 2 inserted into the guide groove is provided with two symmetrically arranged slots 7, which are respectively located at the top and bottom of the crossbar 2. The connecting block 3 is provided with two slide grooves 8 connected to the guide groove, which are symmetrically arranged on the connecting block 3. When one end of the crossbar 2 is inserted into the guide groove, the two slide grooves 8 are respectively aligned with the corresponding slots 7, so that the latch 4 can enter the slot 7.

[0020] A latch 4 is slidably mounted in the slide groove 8, one end of the latch 4 extends to the outside of the connection block 3, and a round plate is fixedly mounted on one end of the latch 4 located outside the connection block 3, so as to facilitate pulling the latch 4 outward. The other end of the latch 4 is plugged into the slot 7. One end of the latch 4 plugged into the slot 7 is an inclined surface, and the inclined surface at one end of the latch 4 is slidably matched with the crossbar 2, so that when the crossbar 2 is inserted into the guide groove in the connection block 3, the latch 4 can be inserted into the slot 7 without pulling the latch 4 outward.

[0021] A gasket 6 is fixedly sleeved on the latch 4, and the gasket 6 is located above the inclined surface of the latch 4. A spring 5 is fixedly installed between the gasket 6 and the top wall of the slide groove 8. When the spring 5 is in a natural state, the gasket 6 will not enter the guide groove in the connecting block 3, so as to prevent the gasket 6 from hindering the insertion of the cross bar 2 into the guide groove.

[0022] The working principle of the utility model is as follows:

[0023] During installation, one end of the cross bar 2 is inserted into the guide groove in the connecting block 3. The cross bar 2 cooperates with the inclined surface of one end of the pin 4 to move the pin 4 upward and compress the spring 5. When the cross bar 2 drives the slot 7 to align with the slide slot 8, the pin 4 is inserted into the slot 7 under the restoring force of the spring 5, thereby restricting the cross bar 2, and the splicing of the column 1 and the cross bar 2 can be completed.

[0024] During disassembly, the latch 4 is pulled outward to disengage the latch 4 from the slot 7, and the cross bar 2 can be pulled outward from the guide groove of the connecting block 3, thereby completing the disassembly of the column 1 and the cross bar 2.
