Description

Technical Field

[0001] This utility model belongs to the field of steel structure roofing technology, specifically relating to a novel horizontal support adjustment device for steel structure roofing. Background Technology

[0002] The turnbuckle adjustment bolt for the horizontal support adjustment device of steel roof structure is a high-strength, telescopically adjustable connecting component, consisting of a two-way threaded rod, a lock nut, and a hook. By rotating the central adjusting nut, the length of the threaded rod can be simultaneously adjusted in both directions, achieving precise tensioning and fine-tuning of the horizontal support system. This effectively compensates for installation errors and structural deformation, and features convenient operation and stable locking, ensuring uniform stress and overall stability of the roof support system. However, it also has drawbacks such as high cost, low tensile strength, and relatively low installation efficiency.

[0003] The authorized patent with application number 202022950654.4 discloses an adjustable turnbuckle-attached scaffold tie rod: it is composed of a U-shaped bolt (1) made of steel and an adjustable turnbuckle (2) connected at one end; the U-shaped bolt includes a U-shaped clip (1a) with its opening facing obliquely upward, and a connecting nut (1b) welded to the opening of the U-shaped clip; the adjustable turnbuckle includes two round steel bars (2a) arranged symmetrically, an upper nut (2b) and a lower nut (2c) welded to the upper and lower ends of the two round steel bars respectively, and a tie rod (2d) with an external thread rod (2e) fitted in the upper nut, the upper end of the tie rod having a ring (2f); the lower nut (2c) of the turnbuckle and the connecting nut (1b) of the U-shaped bolt are connected by a pin (3) passing through the threaded hole of the lower nut and the threaded hole of the U-shaped bolt. This utility model is easy to assemble and disassemble, flexible in layout, and has adjustable and safe ends, making it particularly suitable for the construction of attached scaffolding for high-rise buildings.

[0004] However, in implementing the relevant technology, the following problems were found with the above technical solution: the cost of the basket-type adjusting bolt is high, and different specifications and sizes cannot be made according to the different tensile strength requirements of different structures. In addition, the number of horizontal support components of the basket-type adjusting bolt is large, and the installation process is complicated.

[0005] Therefore, a novel horizontal support adjustment device for steel roof structures is proposed to solve the above problems. Utility Model Content

[0006] This utility model proposes a novel horizontal support adjustment device for steel structure roofs, which solves the problems of high cost of basket-type adjusting bolts in related technologies, inability to manufacture different specifications and sizes according to different tensile strength requirements of different structures, and the large number of horizontal support components of basket-type adjusting bolts, which makes the installation process complicated.

[0007] The technical solution of this utility model is as follows: A novel horizontal support adjustment device for steel structure roofs, comprising: Fixed ear plate; Adjusting bolts connected to one end of the fixed ear plate; The outer wall of the adjusting bolt is threaded with a locking nut and an adjusting nut, and the locking nut and the adjusting nut are arranged opposite to each other; The outer wall of the adjusting bolt is provided with a support pin, the outer wall of the support pin is provided with a shaft pin buckle, and an adjusting bracket is provided between the support pin and the shaft pin buckle. The adjusting bracket has a support rod at its end, a connecting ear plate at its end, and a connecting component on the inner wall of the connecting ear plate for connecting the support rod and the connecting ear plate.

[0008] Preferably, the support pin includes a connecting frame and a sliding ring sleeved on the inner wall of the connecting frame, the sliding ring being slidably connected to the outer wall of the adjusting bolt.

[0009] Preferably, the pin buckle includes a fixing post and a snap-fit ​​edge formed on the outer wall of the fixing post, and the fixing post is fixedly connected to the outer wall of the connecting frame; The outer wall of the snap-fit ​​edge is snapped with a buckle, and the adjusting bracket is rotatably connected to the outer wall of the fixed column, with the adjusting bracket located inside the buckle.

[0010] Preferably, a threaded cylinder is fixedly provided on the outer wall of the fixed ear plate, and the adjusting bolt is threadedly connected to the inner wall of the threaded cylinder.

[0011] Preferably, the connecting assembly includes a connecting through hole formed on the outer wall of the connecting ear plate and a pin inserted into the connecting through hole, the pin passing through the connecting ear plate and the support rod.

[0012] Preferably, the outer wall of the pin is engaged with a fixing buckle, and the outer wall of the pin is fitted with a limiting ring, which is located between the fixing buckle and the connecting ear plate.

[0013] Preferably, both the outer walls of the fixed ear plate and the connecting ear plate are provided with fixing plates, and the inner walls of the fixing plates are provided with connecting bolts for connecting the fixing plates with the fixed ear plates and the connecting ear plates.

[0014] The working principle and beneficial effects of this utility model are as follows: The device can be manufactured in different sizes to meet the varying tensile strength requirements of different structures, thus reducing costs. For example, the tensile strength of the horizontal support, through structural redesign, far exceeds that of the turnbuckle adjusting bolts it was intended to replace. Furthermore, the device has fewer components than the horizontal support components that replaced the turnbuckle adjusting bolts. This streamlined design makes assembly more convenient and the structure simpler. Attached Figure Description
