Description

Technical Field

[0001] This utility model relates to the field of steel structure building construction technology, specifically a positioning device for steel structure buildings. Background Technology

[0002] In steel structure construction, the positioning accuracy of components before welding directly affects the load-bearing capacity and stability of the structure. In particular, the connection between columns and beams and the installation of diagonal support nodes require strict control of height deviation, axis alignment and angular accuracy.

[0003] A search revealed that patent CN218479577U discloses a positioning device for steel structure construction. This device uses an arc-shaped plate and a positioning mechanism to clamp a crossbeam, and a bidirectional screw drives the clamp to move synchronously, preventing the crossbeam from shifting. Simultaneously, a spring and clamp plate work together to achieve a certain range of adjustment. However, this solution has the following shortcomings in practical applications:

[0004] The installation height is difficult to adjust: the curved plate is fixed to the column by locking bolts and nuts, which makes it difficult to fine-tune the installation height. This can easily lead to a large deviation in the installation height of the crossbeam, which cannot meet the requirements of high-precision construction.

[0005] Low installation efficiency: The fixing of the curved plate to the column requires multiple calibrations, the bolt tightening operation is cumbersome, and the construction efficiency is low.

[0006] No angle adjustment function: The mounting plate is fixedly connected to the curved plate, which can only accommodate a single angle (such as 90°). It cannot meet the diverse positioning angle requirements of oblique supports (such as 30°, 45°), irregular nodes, etc., and its use is highly limited.

[0007] Therefore, there is an urgent need for a steel structure positioning device that features highly precise fine-tuning, flexible angle adjustment, and convenient installation to overcome the shortcomings of existing technologies. Utility Model Content

[0008] The purpose of this utility model is to provide a positioning device for steel structure buildings to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A positioning device for steel structure buildings includes a first U-shaped seat and a clamping plate interconnected by multiple bolt and nut assemblies. A second U-shaped seat is slidably mounted on the outer wall of the first U-shaped seat. A linear drive mechanism for driving the second U-shaped seat to move up and down is installed on the outer wall of the first U-shaped seat. A support plate is hinged to the top of the outer wall of the second U-shaped seat via a hinge seat. A horizontal plate is fixedly mounted on the outer wall of the second U-shaped seat. A second screw is installed on the horizontal plate through a threaded hole. The top of the second screw is rotatably connected to a support rod via a bearing seat. A second handwheel is fixedly connected to the bottom of the second screw.

[0011] As a further embodiment of this utility model: multiple guide rods are slidably installed on the top of the horizontal plate, and the top ends of the guide rods are fixedly connected to the support rods.

[0012] As a further embodiment of this utility model, the top surface of the support rod is an arc surface.

[0013] As a further embodiment of this utility model: multiple third screws are slidably installed on the top of the tray near both sides, a pressure plate is provided above the tray, the top ends of the third screws are fixedly connected to the pressure plate, and a third nut is installed on the outer wall of the third screws below the tray.

[0014] As a further embodiment of this utility model: guide rails are fixedly installed on both outer walls of the first U-shaped seat, and sliding sleeves are slidably sleeved on the outer walls of the guide rails, and the sliding sleeves are fixedly connected to the inner wall of the second U-shaped seat.

[0015] As a further embodiment of this utility model: a first screw is rotatably mounted on the outer wall of the first U-shaped seat via a bearing seat, a first nut is fitted onto the outer wall of the first screw, the first nut is fixedly connected to the inner wall of the second U-shaped seat, and a first handwheel is fixedly mounted on the bottom end of the first screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model solves the problem of inconvenient height adjustment of traditional devices. Through the coordinated design of the first screw, the first nut, the guide rail, and the sliding sleeve, millimeter-level height adjustment is achieved, thereby effectively reducing the deviation of the component installation height and meeting construction standards.

[0018] 2. This utility model breaks through the limitation of single-angle positioning.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a positioning device for steel structure buildings includes a first U-shaped seat 1 and a clamping plate 3 interconnected by multiple bolt and nut assemblies 2. A second U-shaped seat 4 is slidably mounted on the outer wall of the first U-shaped seat 1. A linear drive mechanism for driving the second U-shaped seat 4 to move up and down is mounted on the outer wall of the first U-shaped seat 1. A support plate 16 is hinged to the top of the outer wall of the second U-shaped seat 4 through a hinged seat 15. A horizontal plate 10 is fixedly mounted on the outer wall of the second U-shaped seat 4. The horizontal plate 10 is reinforced and fixed by multiple reinforcing ribs on the outer wall of the second U-shaped seat 4. A second screw 11 is installed on the horizontal plate 10 through a threaded hole. The top of the second screw 11 is rotatably connected to a support rod 13 through a bearing seat. A second handwheel 12 is fixedly connected to the bottom of the second screw 11.

[0026] By adopting the above-mentioned solution, this utility model allows for the following: In use, multiple bolt and nut assemblies 2 are used to fix and clamp the first U-shaped seat 1 and the clamping plate 3 to the required height on the surface of the I-beam column. Then, the second screw 11 is rotated on the horizontal plate 10 to push the support rod 13 up and down, causing the support plate 16 to adhere to the top of the support rod 13. This allows for adjustment of the angle of the support plate 16, facilitating the adjustment of the positioning support angle of the I-beam beam. Furthermore, by operating the linear drive mechanism to drive the second U-shaped seat 4 to slide up and down on the surface of the first U-shaped seat 1, the height of the support plate 16 can be adjusted, further facilitating the adjustment of the positioning height of the I-beam beam, making it more convenient to use.

The top ends of the guide rods 14 are all fixedly connected to the support rods 13 to guide the up and down movement of the support rods 13 on the horizontal plate 10, thereby improving the stability of the movement of the support rods 13 and preventing the support rods 13 from rotating with the second screw 11. In addition, the guide rods 14 can also share the radial force on the second screw 11, thereby improving the service life of the second screw 11.

[0028] Specific combination Figure 1 and Figure 2 In one embodiment of this utility model, the top surface of the support rod 13 is an arc surface, so as to better fit with the bottom surface of the support plate 16, thereby providing more stable support for the support plate 16.

[0029] Specific combination Figure 1 , Figure 2 and Figure 4 In one embodiment of this utility model, a plurality of third screws 18 are slidably installed on the top of the support plate 16 near both sides. A pressure plate 17 is provided above the support plate 16. The top ends of the third screws 18 are all fixedly connected to the pressure plate 17. A third nut 19 is installed on the outer wall of the third screw 18 below the support plate 16, so as to facilitate the use of the cooperation between the third screw 18 and the third nut 19 to fix and clamp the end of the I-beam to be welded to the I-beam column between the support plate 16 and the pressure plate 17.

[0030] Specific combination Figure 1-3 In one embodiment of this utility model, guide rails 5 are fixedly installed on both outer walls of the first U-shaped seat 1. Sliding sleeves 6 are slidably sleeved on the outer wall of the guide rails 5. The sliding sleeves 6 are fixedly connected to the inner wall of the second U-shaped seat 4. Through the cooperation of the guide rails 5 and the sliding sleeves 6, the second U-shaped seat 4 can be guided on the surface of the first U-shaped seat 1 to improve the stability of the second U-shaped seat 4 moving up and down.

[0031] Specific combination Figure 1-3 Based on the previous embodiment, the outer wall of the first U-shaped seat 1 is further provided with a first screw 7 rotatably mounted on the bearing seat. The outer wall of the first screw 7 is fitted with a first nut 9. The first nut 9 is fixedly connected to the inner wall of the second U-shaped seat 4. A first handwheel 8 is fixedly mounted on the bottom end of the first screw 7. By rotating the first screw 7 through the first handwheel 8, the second U-shaped seat 4 can be driven to slide up and down on the surface of the first U-shaped seat 1 by the cooperation of the first screw 7 and the first nut 9. The operation is simple and convenient.
