Description

Technical Field

[0001] The utility model relates to a calibration device for building steel structure engineering, belonging to the technical field of building calibration devices. Background Technique

[0002] Steel structure engineering is a structure mainly made of steel, mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect between components or parts. It is one of the main building structure types. During the production process of steel structures, tools are needed to detect and calibrate them.

[0003] According to the calibration device for steel structures disclosed in the publication number CN211992640U, which relates to the field of steel structure calibration. Aiming at the problem that it is inconvenient to manually hold and calibrate steel structures during calibration, the following scheme is proposed. It includes a calibration table. A motor base is welded to the outer wall of the right shell of the calibration table. The top shell of the motor base is bolted to a driving motor. The output shaft of the driving motor is fixedly connected to a first screw rod. The outer ring of the first screw rod is rotatably sleeved with a first screw block, and the outer ring of the first screw rod rotatably penetrates through the right shell of the calibration table. The top shell outer wall of the first screw block is fixedly connected to a fixing rod. The top of the fixing rod is welded to a sliding plate. The top shell of the sliding plate is welded to a fixing box. The design of the utility model is novel, which is convenient for fixing and clamping steel structures. After fixing and clamping, it is convenient to calibrate two steel structures, thereby reducing the error between the two steel structures and being suitable for market promotion. When the above device is in use, when clamping steel structures of different specifications, the stability of clamping them cannot be effectively guaranteed. At the same time, when clamping steel structures of different specifications, the moving distance of the sliding plate is fixed at this time. Therefore, it cannot effectively ensure that the two steel structures can approach each other, resulting in low practicability of the device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a calibration device for building steel structure engineering. The utility model can facilitate the disassembly, assembly and replacement of the device, so as to be applicable to the use of steel structures of different specifications. At the same time, it can ensure that two steel structures can approach each other, thereby facilitating the user to detect and calibrate the steel structures, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A calibration device for a building steel structure project, including a base. At the top of the rear side of the base, support rods are symmetrically and fixedly arranged. At the top of the support rods, a top plate is fixedly arranged. At the top of the base, supports are symmetrically and slidably arranged. At the top of each support, a fixing plate is provided. At the top of each fixing plate, a lower clamping seat is fixedly arranged. At the rear top of each lower clamping seat, a plurality of connecting rods are slidably embedded in an array. On the connecting rods located on the same lower clamping seat, upper clamping seats are fixedly connected. At the bottom of the top plate, a limiting block matching the upper clamping seat is fixedly arranged.

[0007] Furthermore, a first chute is opened at the top of the base. In the inner wall of the middle part of the first chute, a double-headed motor is fixedly arranged. The output ends of the double-headed motor are fixedly connected with screw rods. On each screw rod, a first slider is threadedly sleeved. The top of each first slider is fixedly connected with the bottom of the adjacent support.

[0008] Furthermore, threaded sleeves matching the screw rods are fixedly embedded through the first sliders. Opposite threads are provided on the two screw rods.

[0009] Furthermore, each support and the adjacent fixing plate are fixedly connected through a plurality of locking screws.

[0010] Furthermore, a second chute is opened inside the rear side of each lower clamping seat. In each second chute, a second slider is slidably arranged. The bottom ends of the connecting rods all extend into the adjacent second chute and are fixedly connected with the top of the second slider. Springs are fixedly arranged on each second slider. The top ends of the springs are fixedly connected with the inner wall of the top of the second chute.

[0011] Furthermore, inclined parts matching the limiting blocks are arranged on the upper parts of the adjacent sides between the upper clamping seats.

[0012] Furthermore, anti-slip lines are arranged on the inner walls of the lower clamping seats and the upper clamping seats.

[0013] The beneficial effects of the utility model are:

[0014] The utility model is provided with a fixing plate, a bracket and a limiting block. When in use, when steel structures of different specifications are used, appropriate lower clamping seats and upper clamping seats are selected, and the fixing plate is fixed on the support by using locking screws. Then, the steel structure is placed on the lower clamping seat. At this time, the double-headed motor can drive the screw rod to rotate, and the screw rod drives the first slider to move towards each other. The first slider will drive the support and the fixing plate to move towards each other, so that the fixing plate drives the lower clamping seat and the upper clamping seat to move towards each other. When the upper clamping seat moves towards each other, at this time, the limiting block will push the upper clamping seat to move downward, so that the upper clamping seat pushes the connecting rod and the second slider to stretch the spring downward, and the workpiece can be clamped and fixed by the upper clamping seat and the lower clamping seat. Since the bottom end of the middle part of the limiting block is horizontally arranged, it can ensure that the two steel structures can be close enough, which is convenient for detection and calibration. The utility model can facilitate the disassembly, assembly and replacement of the device, so as to be applicable to steel structures of different specifications, and at the same time, it can ensure that the two steel structures can be close to each other, which is convenient for the user to detect and calibrate the steel structures.

[0025] Specifically, as Figures 1-4 shown, the supports 4 and the adjacent fixing plates 5 are fixedly connected through a plurality of locking screws 14. By using the locking screws 14 for connection, it is convenient to replace the clamping seats.

[0026] Specifically, as Figures 1-4As shown, chutes two 15 are respectively formed inside the rear sides of the lower clamping seats 6.
