Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a large-span truss ultra-thin member suspension point structure. Background Technology

[0002] In building construction, when a truss needs to be lifted, it is usually done by installing lifting lugs on the truss and hooks on the hoist, and then lifting the truss using external equipment. However, when it is necessary to lift some large-span truss ultra-thin members, the wall thickness of the member at the lifting lug position is affected by the truss, resulting in a very thin member wall thickness. The lifting member has a large span and heavy weight, which makes traditional lifting lugs unusable. In addition, due to the large span and heavy weight of the member, the wire rope is entangled and cannot be used for operation. Utility Model Content

[0003] This utility model provides a lifting point structure for ultra-thin members of a large-span truss. It has the advantages of reducing the workload of cutting off the lifting lugs welded to the truss after construction and reducing the subsequent work of grinding and painting after cutting. In addition, it can avoid the problem that the thin wall thickness of the members at the lifting point of the truss may cause damage to the members or even falling members during hoisting, resulting in personal injury and property damage.

[0004] This utility model provides the following technical solution: a large-span truss ultra-thin member suspension point structure, including a "U"-shaped mounting frame. One end of the "U"-shaped mounting frame is fixedly connected to a reinforcing connecting plate. A fixing bolt is inserted inside the reinforcing connecting plate, and threaded connecting rods are fixedly connected to both ends of the fixing bolt. A hanging plate is fixedly connected to the top of the "U"-shaped mounting frame, and a mounting hole is opened inside the hanging plate. A guide plate is fixedly connected to one side of the hanging plate, and the bottom of the guide plate is fixedly connected to the top of the "U"-shaped mounting frame. A connecting frame is symmetrically fixedly connected to the top of the "U"-shaped mounting frame. A damping sliding rail is fixedly connected inside the connecting frame, and a counterweight slider is damped and slidably connected inside the damping sliding rail. Several semi-circular plates are fixedly connected to the inner side of the "U"-shaped mounting frame, and a protective rubber wall is provided on the outside of the several semi-circular plates. The protective rubber wall is fixedly connected to the inner side of the "U"-shaped mounting frame.

[0005] The reinforcing connecting plate has an internal mounting groove, and the fixing bolt is inserted into the mounting groove.

[0006] The threaded connecting rod is threaded with a fixing nut, and an anti-slip rubber pad is fixedly connected to one side of the fixing nut.

[0007] The mounting hole is fixedly connected to a protective wall, and the top of the hanging plate is fixedly connected to a reinforcing plate.

[0008] wherein a guiding slope is cut at the top of the guide plate.

[0009] wherein a counterweight plate is fixedly connected to the top of the counterweight slider.

[0010] wherein a rubber sleeve is fixedly connected to the outside of the semicircular plate.

[0011] The utility model has the following beneficial effects: under the mutual cooperation of the fixing bolt, the threaded connecting rod, the fixing nut and the C-shaped mounting bracket, the hoisting point structure formed outside the truss through the detachable connection between the fixing bolt and the C-shaped mounting bracket can remove the entire hoisting point structure after the truss is hoisted. On one hand, this reduces the workload of workers when cutting off the lifting lugs welded on the truss after construction is completed; on the other hand, it reduces the subsequent work of grinding and painting after cutting. In addition, it can avoid the problem that the thin wall thickness of the component at the hoisting point position of the truss may cause component damage or even component falling, which leads to personal and property damage, and at the same time enables flexible installation of the hoisting point position when hoisting a large-span truss, which helps improve the balance and stability when hoisting a large-span truss.

[0017] Please refer to Figures 1-3This utility model provides the following technical solution: a suspension point structure for ultra-thin members of a large-span truss, including a "U"-shaped mounting frame 1. One end of the "U"-shaped mounting frame 1 is fixedly connected to a reinforcing connecting plate 11. A fixing bolt 2 is inserted inside the reinforcing connecting plate 11, and threaded connecting rods 21 are fixedly connected to both ends of the fixing bolt 2. A hanging plate 3 is fixedly connected to the top of the "U"-shaped mounting frame 1, and a mounting hole 31 is opened inside the hanging plate 3. A guide plate 34 is fixedly connected to one side of the hanging plate 3, and the guide plate 34... The bottom of plate 34 is fixedly connected to the top of "U"-shaped mounting bracket 1. A connecting frame 4 is symmetrically fixedly connected to the top of "U"-shaped mounting bracket 1. A damping sliding rail 41 is fixedly connected inside the connecting frame 4, and a counterweight slider 42 is damped and slidably connected inside the damping sliding rail 41. Several semi-circular plates 13 are fixedly connected to the inner side of "U"-shaped mounting bracket 1, and a protective rubber wall 12 is provided on the outside of the several semi-circular plates 13. The protective rubber wall 12 is fixedly connected to the inner side of "U"-shaped mounting bracket 1.

[0018] In this implementation plan, the "U"-shaped mounting bracket 1, in cooperation with the fixing bolts 2, forms the overall frame of the entire lifting point structure. After installation, the "U"-shaped mounting bracket 1 wraps around the outside of the truss. The fixing bolts 2 are used to lock and limit one side of the "U"-shaped mounting bracket 1, thus fixing it to the outside of the truss. The lifting point structure formed on the outside of the truss through the detachable connection between the fixing bolts 2 and the "U"-shaped mounting bracket 1 allows for easy dismantling of the entire lifting point structure after the truss is lifted. Compared to the traditional method of directly welding the lifting lugs to the truss, this reduces the workload of cutting the welded lugs after construction and also reduces the subsequent work of sanding and repainting after cutting. Furthermore, the lifting point structure formed on the outside of the truss by the cooperation of the "U"-shaped mounting bracket 1 and the fixing bolts 2 avoids the risk of damage due to truss lifting... The thin walls of the components at the lifting points may cause damage or even fall during hoisting, resulting in personal injury and property damage. However, this design allows for flexible installation at the lifting points when hoisting large-span trusses, improving balance and stability. The lifting plate 3, installed on top of the "U"-shaped mounting frame 1, forms a connecting assembly with the external hooks in conjunction with the mounting holes 31. When hoisting large-span trusses, the external hooks are installed inside the mounting holes 31, and the truss is rotated using external equipment. The guide plate 34 on one side of the lifting plate 3 guides the lifting ropes and hooks. The connecting frame 4, installed on top of the "U"-shaped mounting frame 1, forms an adjustment assembly with the damping sliding rail 41 and counterweight slider 42 to adjust the front and rear balance of the truss during transport, helping to maintain good balance after hoisting.

[0019] The reinforcing connecting plate 11 has an internal mounting groove 111, and the fixing bolt 2 is inserted into the mounting groove 111; wherein the mounting groove 111 is used to provide space for the installation of the fixing bolt 2.

[0020] A fixing nut 22 is threaded onto the threaded connecting rod 21, and an anti-slip rubber pad 23 is fixedly connected to one side of the fixing nut 22; wherein the fixing nut 22 is used to limit the threaded connecting rod 21 inside the reinforcing connecting plate 11, and the anti-slip rubber pad 23 is used to increase the friction between the fixing nut 22 and the contact surface of the reinforcing connecting plate 11.

[0021] The mounting hole 31 is fixedly connected to a protective wall 32, and the top of the hanging plate 3 is fixedly connected to a reinforcing plate 33; the protective wall 32 is used to increase the friction between the hanging plate and the hook, and the reinforcing plate 33 plays a reinforcing role.

[0022] The top of the guide plate 34 is cut with a guide slope 341; the guide slope 341 plays a guiding and transitioning role.

[0023] The top of the counterweight slider 42 is fixedly connected to a counterweight plate 421; the counterweight plate 421 serves as a limit and is located at the top of the connecting frame 4.

[0024] The semicircular plate 13 is externally fixedly connected with a rubber sleeve 131, which serves a protective function.

[0025] The working principle and usage process of this utility model are as follows: When it is necessary to lift a large-span truss, firstly, the "U"-shaped mounting bracket 1 is installed on the outside of the truss. During the installation process, several "U"-shaped mounting brackets 1 are evenly installed on the outside of the truss. When installing the "U"-shaped mounting bracket 1, the truss is first clamped on the outside of the truss, and then the fixing bolt 2 is inserted into the inside of the mounting groove 111, and the fixing bolt 2 is limited by the fixing nut 22. Then, the hook of the external lifting equipment is hung inside the mounting hole 31. When all the "U"-shaped mounting brackets 1 are installed with the truss, the truss can be lifted a short distance to check the balance of the truss after lifting. When the frame becomes unbalanced, the balance of the truss during the lifting process can be adjusted by adjusting the position of the counterweight slider 42 inside the damping sliding rail 41. In addition, after the "U"-shaped mounting bracket 1 is installed with the truss, the "U"-shaped mounting bracket 1 and the truss are locked together by the cooperation of the fixing bolt 2 and the fixing nut 22. When the "U"-shaped mounting bracket 1 is locked, the inner side of the "U"-shaped mounting bracket 1 can be in close contact with the truss. In this state, the semi-circular plate 13 on the inner side of the "U"-shaped mounting bracket 1 can form a surface with concave and convex shapes with the cooperation of the protective rubber wall 12, which helps to improve the stability of the "U"-shaped mounting bracket 1 outside the truss.
