Description

Technical Field

[0001] This application relates to the technical field of steel structure assembly, and particularly relates to a adjustable and alignable jig for steel structure assembly. Background Art

[0002] Currently, with the rapid development of modern construction industry and the continuous update of construction methods, steel structure buildings have also entered a new stage of development, and the structural forms are increasingly innovative; large buildings are usually in the form of trusses during design, and the trusses need to be placed on jigs for assembly.

[0003] Currently, jigs are generally welded by channel steel, I-beams, etc. When the elevation needs to be adjusted, wooden squares or steel plates are padded at the bottom of the jig for adjustment. However, the time spent on padding is relatively long, and the adjustment range is also limited. At the same time, the sizes of the padded items are different, resulting in deviations from the actual required sizes after adjustment, reducing the quality of the truss after assembly, and thus reducing the assembly efficiency and quality of the truss. Summary of the Invention

[0004] In order to improve the assembly efficiency and quality of trusses, this application provides an adjustable and alignable jig for steel structure assembly.

[0005] An adjustable and alignable jig for steel structure assembly provided by this application adopts the following technical solution:

[0006] An adjustable and alignable jig for steel structure assembly includes a plurality of support frames and a support mechanism arranged on each support frame for supporting and positioning the steel structure. A plurality of support holes are vertically spaced apart on the support frame. The support mechanism includes:

[0007] A plurality of support platforms, and a plurality of the support platforms are respectively detachably installed on a plurality of support holes through a connection mechanism;

[0008] A plurality of U-shaped support rods, and a plurality of the U-shaped support rods are respectively detachably installed on a plurality of support platforms through fixing components and are used for supporting and positioning the steel structure;

[0009] A plurality of positioning plates, and a plurality of the positioning plates are respectively arranged on a plurality of support platforms and are used for positioning the steel structure located on the U-shaped support rods.

[0010] By adopting the above technical solution, place the support frame on the ground, and then fixedly install multiple support platforms onto multiple mounting holes through a connecting mechanism, thereby realizing the installation of multiple U-shaped support rods. Then place the steel structure onto the multiple U-shaped support rods, and the positioning plate positions the steel structure. Next, connect multiple steel structures together and assemble them to obtain a truss. When adjusting the elevation, only need to adjust the positions of the support platform and the U-shaped support rods as required, and at the same time, only need to calibrate the elevation of one of the U-shaped support rods to achieve the calibration of the positions of multiple U-shaped support rods, thereby realizing adjustability and calibratability, so as to improve the assembly efficiency and quality of the truss.

[0011] At the same time, U-shaped support rods of different specifications and sizes can be replaced, so as to be more convenient to adapt to the support of steel structures of different sizes, thereby further shortening the time spent during truss assembly and further improving the truss assembly efficiency. Moreover, it is easy for items to slip under the support frame, so this application also improves the safety during truss assembly compared with laying items.

[0012] Optionally, the connecting mechanism includes:

[0013] A connecting screw, the connecting screw is arranged on the support platform and passes through the support hole;

[0014] A connecting nut, the connecting nut is threadedly connected to the connecting screw and makes the support platform and the connecting nut abut against the support frame for positioning;

[0015] A locking assembly, the locking assembly is arranged on the support platform and is used for locking the support platform and detachably connecting two adjacent support platforms together.

[0016] By adopting the above technical solution, pass the connecting screw through the outside of the support hole, and the support platform abuts against the support frame. Then thread the connecting nut onto the connecting screw, so that the connecting nut abuts against the support frame for positioning. When the connecting nut is disassembled from the connecting screw, the position of the support platform can be adjusted, so as to realize the convenience when adjusting and installing the position of the support platform. At the same time, the locking assembly locks the position and angle of the support platform and fixedly connects two adjacent support platforms together, thereby improving the accuracy after the support platform is installed, so as to improve the truss assembly efficiency and assembly quality. At the same time, multiple support platforms are also connected together to share the force, making the falsework more stable during truss assembly and improving the safety during truss assembly.

[0017] Optionally, the locking assembly includes:

[0018] A locking column, the locking column is arranged on the support platform, and the connecting screw is arranged on the support platform;

[0019] Locking plate, locking holes are provided at both ends of the locking plate, and the locking column is inserted and installed in the locking holes after the two locking plates are spliced; the support platform and the support frame are pressed against the splicing part of the two locking plates for positioning;

[0020] Locking rod, the locking rod is arranged on the locking plate and is inserted into the support hole for positioning.

[0021] By adopting the above technical solution, the two locking plates are spliced together, and then the locking rod is inserted and installed into the support hole to position the two locking plates. Then the locking column is inserted and installed into the locking holes after the two locking plates are spliced, so that the connecting screw rod passes through the support hole, and when the connecting nut abuts against the support frame, the support platform and the support frame are pressed against the two locking plates for positioning, so as to realize the fixed connection of two adjacent support platforms. Therefore, the forces on multiple support platforms are balanced, the falsework is more stable during the truss assembly process, and the safety during the truss assembly process is improved; at the same time, the support platform is also positioned at the required angle, so the assembly quality of the truss is improved.

[0022] Optionally, locking grooves are provided at the opposite ends of the two locking plates, and two adjacent locking plates are spliced together by inserting rods inserted into the locking grooves.

[0023] By adopting the above technical solution, the two ends of the inserting rod are inserted and installed into the locking grooves of the two locking plates, so that the two locking plates are abutted together to complete the assembly. Therefore, the convenience during assembly is improved, and the assembly efficiency of the truss is improved.

Then the block is clamped and installed on the connecting rod to position the support platform. Then the positioning component fixedly connects two adjacent blocks together, so as to block the block from separating from the connecting rod, thereby realizing the fixation of the support platform. At the same time, unlocking the positioning component can successively remove the block and the support platform, thus improving the convenience during the disassembly and installation of the support platform and improving the assembly efficiency of the truss;

[0028] The simultaneous positioning component fixedly connects the two support platforms together, thereby further improving the accuracy of the distance between two adjacent U-shaped support rods, while improving the assembly quality of the truss. Moreover, the positioning component distributes the forces on the two adjacent support platforms and U-shaped support rods, thereby improving the support effect of multiple U-shaped support rods on the truss and enhancing the safety during truss assembly.

[0029] Optionally, the positioning component includes:

[0030] A positioning rod, with both ends of the positioning rod being snap-fitted on two adjacent blocks respectively;

[0031] Two wedge-shaped blocks, which are snap-fitted at the connection of the positioning rod and the two blocks for positioning.

[0032] By adopting the above technical solution, the positioning rod is snap-fitted onto the two blocks, and then the two wedge-shaped blocks are respectively snap-fitted at the connection of the positioning rod and the two blocks to prevent the positioning rod from detaching from the blocks, thereby realizing the fixed connection of the two blocks. After pulling out the two wedge-shaped blocks, the positioning rod can be removed to unlock the locking of the two blocks, so as to realize the connection and disassembly of the two blocks, while also improving the convenience during operation and further enhancing the assembly efficiency of the truss.

Then, the elevation of the measuring platform can be measured, and based on the measurement data, the elevations of multiple U-shaped supporting rods can be calibrated. Therefore, even when there is a steel structure placed on the U-shaped supporting rod, the elevation of the U-shaped supporting rod can still be calibrated.

When there is a support platform installed on the support hole at the lowest position, the top of the first support rod is installed in the detection hole; otherwise, the top of the first support rod is installed in the support hole below the support platform, so that the top of the support rod can be moved up as much as possible to improve the support effect of the first support rod on the support frame. The top of the second support rod is installed in the support hole, then the bottom end of the force dividing rod is inserted and installed on the second support rod, and then the top end of the force dividing rod is connected to the support hole.

At the same time, the first groove and the second groove cooperate to form a rhombus, and a rhombus-shaped insertion groove 85 is opened on the side wall of the clamping block 82 facing away from the support frame 1, and the projection of the insertion groove 85 in the horizontal direction coincides with the projection after the cooperation of the first groove and the second groove; at the same time, the two wedge-shaped blocks 92 are respectively located at both ends of the positioning rod 91, and the wedge-shaped blocks 92 are clamped into the insertion groove 85, and the wedge-shaped blocks 92 are inserted into the rhombus formed by the cooperation of the first groove and the second groove to prevent the positioning rod 91 from moving and disengaging from the clamping groove 84; at the same time, a pull ring 93 is fixedly installed at one end of the wedge-shaped block 92 away from the support frame 1, and the pull ring 93 facilitates the installation and disassembly of the wedge-shaped block 92; and an anti-disengagement block 94 is clamped into the clamping groove 84 of the lowermost clamping block 82, and the anti-disengagement block 94 abuts against the connecting rod 81 to position the clamping block 82, and the wedge-shaped block 92 is inserted into the insertion groove 85 and the anti-disengagement block 94 to position the lowermost clamping block 82.

[0084] The working principle of the embodiment of the present application is as follows:

[0085] Pass the connecting rod 81 out of the support hole 12, and then snap the clamping block 82 onto the clamping groove 83 to install multiple support platforms 21 in this way. Then snap the positioning rod 91 onto the clamping groove 84 so that the second groove and the first groove on the positioning rod 91 cooperate to form a rhombus. Then snap two wedge-shaped blocks 92 onto both ends of the positioning rod 91. Finally, snap the anti-disengagement block 94 onto the clamping groove 84 of the lowermost clamping block 82, and then insert the wedge-shaped block 92 into the insertion groove 85 and the anti-disengagement block 94 to install multiple support platforms 21 and connect the multiple support platforms 21 together, thereby improving the stability of the jig, and at the same time improving the convenience of installing and disassembling the jig, and improving the assembly quality and efficiency of the truss; at the same time, after removing the wedge-shaped block 92 and the positioning rod 91, the position of the support platform 21 can be changed, improving the convenience of adjusting the support platform 21 and further improving the assembly efficiency of the truss.

[0086] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
