Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, in particular to a side positioning and fixing device for a hoisting clamp. Background Art

[0002] The prefabricated floor slabs used in existing buildings are cast in the workshop. The walls are prefabricated with steel skeletons inside the walls, and then cement is poured. They are transported to the construction site and assembled by workers and cranes. Prefabricated floor slabs are not absolutely easy to use. It is difficult to align the positioning holes of the walls during the assembly process. If there is a deviation, the positioning steel bars may be directly sawed off, resulting in poor wall splicing firmness, and the gaps in the wall splicing will have problems such as poor sealing and cracking in the later stage. Therefore, it can be carried out through the prefabricated forming skeleton, which is a semi-prefabricated construction method. It can make the forming skeletons fully fixed and avoid the problem of poor sealing of the gaps between the walls. The existing M-shaped steel forming skeleton has been developed as the main structural support, and then the steel bars are tied and fixed to form a steel cage in the shape of the plate, which greatly reduces the assembly time of the forming skeleton and improves efficiency.

[0003] The formed frame is the main rigid support built into the wall. The prefabricated steel cage needs to be transported and assembled. Since the steel bars are fixed by bundling or welding, directly lifting the formed frame will cause uneven local force, and the formed frame will be deformed due to the unstable center position. When lifting the steel frame, the corresponding clamps are fixed on both sides of the steel frame. The clamps include square tubes on both sides, which are used to fix the two sides of the steel frame. The square tubes are connected and installed with beams to form a frame structure. The force is lifted by the frame to prevent stress deformation of the steel structure. The existing method of fixing beams and square tubes is to directly use bolts and nuts. The positioning points are relatively simple. The square tubes lack the clamping effect on the steel frame, which makes the support of the steel frame unstable. In addition, when the square tubes are disassembled for secondary use, the disassembly process is cumbersome, which affects work efficiency. Utility Model Content

[0004] The utility model aims to provide a side positioning and fixing device for a lifting clamp, which increases the clamping tightness of the clamp on the steel frame by installing an adjusting and fixing device on the side of the clamp, facilitates disassembly and reuse, and improves the stability of the clamp.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] A side positioning and fixing device for a lifting fixture comprises square tubes installed on both sides of a steel frame, the square tubes on both sides are parallel to each other, a crossbeam is connected between the square tubes, the length direction of the crossbeam is perpendicular to the length direction of the square tubes, and a frame structure is formed after splicing;

[0007] The crossbeam has a groove body along the length direction, a slider is installed in the groove body, the slider is limitedly installed in the groove body and slides along the length direction of the groove body, and the intersection of the square tube and the crossbeam is connected to the slider through a connecting piece, so that the square tube is fixed to the slider;

[0019] The crossbeam 2 has a groove body 21 along the length direction, and a slider 3 is installed in the groove body 21. The slider 3 is limitedly installed in the groove body 21 and slides along the length direction of the groove body 21. The intersection of the square tube 1 and the crossbeam 2 is connected to the slider through a connecting piece, so that the square tube 1 is fixed to the slider 3; the square tube fixes the slider, and the slider is located in the groove body and adjusted along the length direction of the groove body.

[0020] The end of the crossbeam 2 has a pressing component for driving and pressing the square tube 1. The pressing component fixes the end of the crossbeam and is used to drive the square tube to move along the length direction of the crossbeam, so that the square tube can press the steel frame tightly, reducing the use of fastening steel bars between the steel frame, the crossbeam and the square tube, and achieving a very stable effect of installing the steel structure. When disassembling the frame, you only need to adjust the pressing component to release the tightening force, and the square tube will be separated from the side of the steel structure under the sliding action of the slider, so as to achieve the purpose of rapid disassembly, greatly improving the convenience of disassembling and assembling the steel frame and improving work efficiency.
