[0002] With the rapid development of cities, the functional requirements for large-space public buildings have increased. Steel structure buildings are widely used in large-span structures due to their light weight and good stress resistance. However, there are safety hazards in the use and construction of large-span steel structures, which also puts higher requirements on the design and construction of steel structures. Pre-stressing the roof of a large-span steel structure during construction is an important test to ensure construction safety and use safety. It provides data support for improving the bearing capacity and stability of steel structure roofs. In the existing bearing capacity and deformation detection technology, whether it is direct compression or drop-pull method, it is necessary to allocate a large weight, which makes pre-stressing construction difficult and inefficient.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0016] like Figures 1 to 3 In the embodiment of the steel structure roof anti-compression and anti-deformation device shown in the utility model, the steel structure roof anti-compression and anti-deformation device includes a main body and a tensioning device, the main body includes two limit blocks 2 and a sliding rod 3, the two limit blocks 2 are fixedly connected to the two ends of the sliding rod 3, the sliding rod 3 is slidably connected to two sliders 4, the two sliders 4 are respectively hinged with top support rods 5, the other ends of the two top support rods 5 are hinged to each other, the tensioning device includes a steel cable 6 and a tensioner 7, the tensioner 7 is installed on the steel cable 6, and the steel cable 6 is used to connect the top support rod 5 and the steel structure roof 1.

[0017] Specifically, before the pre-stressing construction, the two ends of the device body are fixedly connected to the bottom of the two ends of the steel structure roof 1, and the steel cable 6 is connected to the pressure point of the steel structure roof 1 and the top support rod 5, and the steel cable 6 is tightened by the tensioner 7. At this time, the slider 4 on the slide bar 3 is pressed against the limit block 2, and the tensioner 7 continues to increase the tension. Under the influence of the tension, the slider 4 at the end of the top support rod 5 presses against the limit block 2 until the tension of the tensioner 7 reaches the pre-stressing requirement. In this process, the steel cable 6 transmits the tension to the top support rod 5, and the top support rod 5 converts the tension into the pressure of the slider 4 on the limit block 2, and finally converts it into the tension on the slide bar 3, due to the pressure on the steel structure roof 1 to be achieved by the pre-stressing. The device realizes the pre-stressing of the steel structure roof 1 by replacing the pre-stressing pressure with the tension under the steel structure roof 1. The tension under the steel structure roof 1 is finally converted into the tension on the slide bar 3 through the device, so that it does not need to be realized by heavy objects. It should be noted that the main structure of the device is made of high-strength steel. The elongation of the slide rod 3 in this process can be ignored. The tensioner 7 adopts the wire tension tester described in application number 200920309358.7, which has tension control and tension display functions.

[0018] In one embodiment of the present application, preferably, both ends of the main body are respectively provided with hinged supports 8 fixedly connected to the steel structure roof 1. The hinged supports 8 at both ends are provided so that the main body and the steel structure roof 1 can rotate relative to each other, so as to avoid the influence of the steel structure roof 1 on the deformation of the main body during the implementation process. In addition, a retractable rod can be provided between the hinged support 8 and the limit block 2 according to the span of the pre-stressed steel structure roof 1 to meet the requirements of different spans.

[0019] In one embodiment of the present application, preferably, the hinge position of the two top support rods 5 is located at the lower part of the main body, and the total length of the two top support rods 5 is greater than the length of the slide rod 3. When the steel cable 6 is tightened, the slide block 4 needs to be pressed outward toward the limit block 2, so the hinge position of the top support rod 5 needs to be set at the lower part of the main body and the total length needs to be greater than the length of the slide rod 3.

[0020] In one embodiment of the present application, preferably, a plurality of ear plates 9 are provided on the top support rod 5, and the position of the ear plate 9 is perpendicular to the pressure point of the steel structure roof 1. The ear plate 9 is set according to the number and position of the pre-stress pressure point of the steel structure roof 1. The ear plate 9 and the pressure point are in a vertical position to make the data more accurate and consistent with the designed force direction.

[0021] In one embodiment of the present application, preferably, there are two sliding rods, and the top support rod 5 and the steel cable 6 are both located between the two sliding rods 3, so that the force plane is consistent with the central plane of the main body, so that the structure of the device is stable during the pre-stressing construction process to avoid the risk of overturning.
