Description

Technical Field

[0001] The present invention relates to the technical field of earthquake resistance testing, and in particular to an earthquake resistance testing device for a high-rise building steel structure. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. They typically consist of components such as beams, columns, and trusses made from sections and plates. They utilize rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components are typically connected using welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to rust and generally require rust removal, galvanizing, or coating, as well as regular maintenance.

[0003] Before the construction of existing steel structures, the steel structure model of high-rise buildings needs to be tested for seismic resistance. Traditional seismic resistance testing equipment may cause the steel structure to collapse during the test. If the test area is not protected, the steel structure will collapse at will and hit the surrounding construction equipment, thereby reducing the safety of the seismic resistance testing device. In addition, during the connection between the steel structure and the seismic resistance testing device, most of the fixing methods are fixed by bolts. Since the steel structure is not easy to move after placement, it will cause offset when using bolts to fix it. Summary of the Invention

[0045] The working principle of this embodiment is:

[0046] First, start the crane to lift the building steel structure and place it on the supporting plate 5. Then, align the connection holes of the building steel structure with the bolt connection holes 7 and then connect the steel structure of the high-rise building to the bolt connection holes 7 of the L-shaped mounting plate 6 through bolts. Since the supporting plate 5 is installed in the No. 1 slide 4 of the bearing plate 8, the supporting plate 5 is located in the No. 1 slide 4 and moves horizontally to facilitate the installation of the supporting plate 5 and the building steel structure. After the connection is completed, use the crane to lift the building steel structure and move it. You can push the supporting plate 5 along the No. 1 slide 4 to the top of the bearing plate 8. When the supporting plate 5 is extended, the steel structure can be installed. On the contrary, when the supporting plate 5 is returned to its position, the steel structure can be subjected to an earthquake test. When the supporting plate 5 is pushed to the top of the bearing plate 8, one side of the supporting plate 5 contacts The limiting rod 104 is used to push the limiting rod 104 to move, and the limiting rod 104 can drive the fixing ring 105 and the rotating rod 101 to rotate through the extension rod 103. The fixing ring 105 is installed with a No. 1 transmission rod 107 and a No. 2 transmission rod 108 through the mounting sheet metal 106 on both sides. The No. 1 transmission rod 107 and the No. 2 transmission rod 108 are respectively connected to the mounting plate 109, which can push the mounting plate 109 to rotate around the central axis 110. When the mounting plate 109 rotates around the central axis 110, the distance between the two No. 2 slide grooves 115 can be adjusted, thereby driving the clamping rod 114 to move inward, and the clamping rod 114 can be inserted into the card slot of the steel structure of the building, so as to achieve the installation and fixation of the steel structure of the building. On the one hand, it can be more The steel structure of the building can be installed quickly. On the other hand, the steel structure of the building can be firmly connected to the supporting plate 5, so that the vibration force can be more directly transmitted to the steel structure of the building and the steel structure of the building can be effectively tested for earthquake resistance. At the same time, when the supporting plate 5 moves to the top of the supporting plate 8, the rotation of the rotating rod 101 can drive the No. 1 bevel gear 102 to rotate. The No. 1 bevel gear 102 is connected to the No. 2 bevel gear 202 through the engagement of the teeth, which can drive the rotating shaft 201 to rotate. The lower push rod 203 rotates around the rotating shaft 201. The lower push rod 203 is connected to the fixed shaft 205 through the upper support rod 204, which can push the protective baffle 11 to move up and down in the side limit block 9, and the limit on both sides of the building steel structure can be achieved by lifting. When the fixed shaft 205 rotates, the driven gear 206 is connected to the fixed bracket 207 through the engagement of the teeth, which can drive the fixed bracket 207 to move along the limiting slide rail 208. The extended baffle 209 at the upper end of the fixed bracket 207 can be extended for a second time, so that it can be linked with the rotating rod 101 and installed together synchronously, thereby reducing the loss of parts and improving the practicality and safety of the seismic test device. When the supporting plate 5 moves along the No. 1 slide 4 to the side of the bearing plate 8, its clamping rod 114 will be retracted from the slot opened in the steel structure, and the protective baffle 11 will be retracted into the side limit block 9. Then, a crane can be used to lift the building steel structure off the supporting plate 5 to complete a seismic test of the high-rise building steel structure.The steel structure seismic test device can also be used for cyclic testing, thereby improving its practicality. During the seismic test, the vibration generator 14 is activated to cooperate with the hydraulic telescopic rod 13. The hydraulic telescopic rod 13 can limit the bearing plate 8, thereby driving the bearing plate 8 to vibrate up and down, thereby simulating the vibration force to test the steel structure.

[0047] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
