Description

A prefabricated high-strength prestressed zigzag roof truss U-shaped hoisting accessory Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a prefabricated high-strength prestressed zigzag roof truss U-shaped hoisting accessory. Background Technology

[0002] Reinforced concrete zigzag roof trusses are the main load-bearing structural components of industrial plant roofs. According to the "Reinforced Concrete Zigzag Roof Trusses" atlas, reinforced concrete zigzag roof trusses are divided into various spans, but the structural types are roughly the same. Prestressed zigzag concrete roof trusses are a type of reinforced concrete zigzag roof trusses. Because the single span length of precast components (reinforced concrete zigzag roof trusses) is relatively long, it is inconvenient to transport them. The processing of components is basically carried out on-site prefabrication.

[0003] The announcement number CN217323015U describes a prefabricated prestressed zigzag concrete roof truss U-shaped hoisting accessory, which includes a connecting body and a hoisting body. The connecting body and the hoisting body are integrally formed. The connecting body is provided with a hoisting locking bolt, and the hoisting body is provided with a hoisting port. Compared with existing technologies, this utility model adopts an integrated design, which can avoid the wear of the hoisting wire rope caused by direct contact between the wire rope and the prefabricated prestressed zigzag concrete roof truss. The hoisting points are pre-arranged and fixed, which makes the hoisting safe and stable, not easy to break, and safe. At the same time, the through holes adopt a through-type fixation, which can also serve as temporary support with the temporary fixing parts of the frame after hoisting, further enhancing safety and stability. However, the above-mentioned prefabricated prestressed zigzag concrete roof truss U-shaped hoisting accessories are not flexible enough. When the device is connected to the roof truss for hoisting, through holes of a certain distance need to be opened on the outside of the roof truss. However, it is difficult to ensure that the opening spacing is constant during the opening process, which makes it cumbersome to measure the distance for each opening. If the spacing is not correct, it is necessary to repeatedly open the holes, which adds extra difficulty to the operation and hoisting complexity. Therefore, it is necessary to provide a new prefabricated high-strength prestressed zigzag roof truss U-shaped hoisting accessory to solve the above technical problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a prefabricated high-strength prestressed zigzag roof truss U-shaped hoisting accessory, which has the advantages of being adjustable and easy to align and hoist, and solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated high-strength prestressed zigzag roof truss U-shaped hoisting accessory, comprising: a hoisting body, wherein a connector is fixedly connected to the top of the hoisting body, and two through holes are opened inside the hoisting body, with two locking bolts commonly engaged inside the two through holes; an adjusting assembly, wherein the adjusting assembly includes a fixed frame, wherein two sliding rods are slidably connected inside the fixed frame, wherein a limit sleeve is fixedly connected to the bottom of each of the two sliding rods, and a threaded sleeve is fixedly connected to the top of each of the two sliding rods, with a bidirectional threaded rod rotatably connected inside the two threaded sleeves; and a reinforcing assembly, wherein the reinforcing assembly includes an alloy frame, the alloy frame being embedded within the hoisting body. The alloy frame is made of tungsten steel. During hoisting, holes are first drilled in the roof truss. After drilling, the two threaded rods are rotated so that the two threaded sleeves move towards or away from each other on the outside of the two threaded rods. Through the linkage of the two sliding rods, the two limiting sleeves can be aligned with the two round holes on the outside of the roof truss. Then, the locking bolt is passed through to complete the hoisting connection operation. There is no need to accurately measure the drilling spacing on the outside of the roof truss during the process, making the hoisting assembly more efficient and faster. At the same time, during use, the embedded tungsten steel alloy frame can improve the rigidity of the overall device, improve the tensile strength and hoisting capacity of the overall device during hoisting operations, and improve durability and stability during hoisting.

[0006] Preferably, the connector has a lifting hole inside, which facilitates the use of wire rope to connect the lifting body to the lifting machine for lifting operations.

[0007] Preferably, the connector is uniformly fixedly connected to the outer sides of both sides, and the reinforcing ribs are fixedly connected to the top of the hoisting body. The reinforcing ribs can improve the connection strength between the connector and the hoisting body.

[0008] Preferably, both ends of the locking bolts are threaded with nuts, and the locking bolts pass through both the through hole and the limiting sleeve. The nuts can enhance the limiting effect of the locking bolts during the connection and limiting process.

[0009] Preferably, the bottom of the fixed frame has two sliding grooves, and the two sliding rods are slidably connected inside the two sliding grooves respectively. The sliding grooves can limit the sliding trajectory of the sliding rods and improve the stability of the overall device during use.

[0010] Preferably, both threaded sleeves are threaded to the outside of the bidirectional threaded rod, and the rotating shaft of the bidirectional threaded rod is connected to the inside of the fixed frame. The bidirectional threaded rod can be rotated so that the two threaded sleeves are displaced towards or away from each other outside the bidirectional threaded rod, thereby achieving an adjustment function.

[0011] Preferably, a turntable is fixedly connected to the end of the bidirectional threaded rod, the turntable extending to the outside of the fixed frame, the turntable facilitating the user to apply force to control the rotation of the bidirectional threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. In the hoisting process of this utility model, holes are first drilled in the roof truss. After drilling, the two threaded sleeves are rotated to move towards or away from each other outside the two threaded rod. Through the linkage of the two sliding rods, the two limiting sleeves can be made to coincide with the two round holes on the outside of the roof truss. Then the locking bolt is passed through to realize the hoisting connection operation. There is no need to accurately measure the drilling spacing on the outside of the roof truss during the process, making the hoisting and assembly process more efficient and faster.

[0014] Second, in the process of using the hoisting main body, the embedded tungsten steel alloy frame can improve the overall rigidity of the device, thereby improving the tensile strength and hoisting capacity during hoisting operations, as well as enhancing durability and stability during hoisting.
