Description

Technical Field

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is usually composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0003] Before the construction of existing steel structures, the steel structure model of high-rise buildings needs to be tested for seismic resistance.

[0045] The working principle of this embodiment is:

[0046] First, start the crane to hoist 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 groove 4 of the bearing plate 8, the supporting plate 5 is located in the No. 1 slide groove 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 hoist the building steel structure to move, and then push the supporting plate 5 along the No. 1 slide groove 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 a seismic 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, and 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 clamping groove 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 and 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 seismic test of the steel structure of the building can be effectively performed. At the same time, when the supporting plate 5 moves to the top of the bearing plate 8, the rotation of the rotating rod 101 can drive the No. 1 bevel gear 102 to rotate, and the No. 1 bevel gear 102 is connected to the No. 2 bevel gear 202 through the engagement of the card teeth, which can drive the rotation shaft 201 to rotate, and the lower push rod 203 rotates around the rotation shaft 201 as the center, and 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 be located in the side limit block 9 and lift up and down, and the limit on both sides of the building steel structure can be achieved through lifting. When the fixed shaft 205 rotates, the driven gear 206 can be connected to the fixed bracket 207 through the engagement of the teeth, and the fixed bracket 207 can be driven 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 in height, 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 groove 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 away from the supporting plate 5 to complete a seismic test of the high-rise building steel structure.The steel structure seismic test device can be cycled to improve the practicality of the steel structure seismic test device. During the seismic test, the vibration generator 14 is started to cooperate with the hydraulic telescopic rod 13. The hydraulic telescopic rod 13 can limit the bearing plate 8, which can drive 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.
