Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a bottom formwork reinforcement device for the upper support pier of a seismic isolation bearing and its construction method. Background Technology

[0002] Traditional seismic design aims to ensure that the structure itself has sufficient strength, stiffness, and ductility, so that the building is "undamaged in minor earthquakes, repairable in moderate earthquakes, and does not collapse in major earthquakes," thereby mitigating earthquake disasters. However, with the rapid development of society and the economy, a large number of buildings of different natures and types have sprung up like mushrooms after rain. This not only brings technical challenges to seismic isolation design, but also to the construction of seismic isolation systems under complex structures. Seismic isolation bearings are the most traditional method of damping, but the formwork erection of the seismic isolation bearing piers in complex structures is often an area that is not adequately considered during formwork construction. Ordinary steel pipe supports are difficult to fit into the upper and lower piers of the seismic isolation bearing. Although using timber for support is more convenient, the weight of the upper pier concrete is often large, and timber support can easily cause deformation of the bottom formwork, thus affecting the safety of the seismic isolation structure.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a bottom formwork reinforcement device and its construction method for the upper support pier of a seismic isolation bearing are provided to solve the problem that the use of wooden supports for the upper support pier casting formwork of existing seismic isolation bearings can easily lead to bottom formwork deformation.

[0005] To achieve the above objectives, a bottom formwork reinforcement device for the upper support pier of a seismic isolation bearing is provided, comprising:

[0006] Two support assemblies are arranged opposite to each other. Each support assembly includes four support plates. Each support plate has a head end and a tail end. The head end forms a slider. The side of each support plate has a groove arranged along the length of the support plate. The head end slides into the groove of the other support plate so that the four support plates are connected end to end to form a rectangular sleeve hole. The rectangular sleeve holes of the two support assemblies are respectively fitted onto the top and bottom of the seismic isolation bearing. The support plate of the support assembly at the bottom of the seismic isolation bearing is laid on the lower pier.

[0007] Multiple support components, each support component including two blocks and an adjustable length support rod, the support rod being connected to the two blocks, the support component being supported between opposite sides of the support plates of the two support components, the multiple support components being spaced apart along the circumferential direction of the rectangular sleeve hole.

[0008] Furthermore, the groove opening extends in opposite directions to form an anti-detachment lip plate, and limit blocks are formed on opposite sides of the slider, with the limit blocks abutting against the inner side of the anti-detachment lip plate.

[0009] Furthermore, the width of the groove gradually decreases from the bottom of the groove towards the opening of the groove, and the cross-section of the slider is adapted to the cross-section of the groove.

[0010] Furthermore, the support rod includes:

[0011] Two screws, which are respectively connected to the two blocks;

[0012] A threaded sleeve, the two ends of which are respectively screwed into the two screws.

[0013] Furthermore, the support rod includes a screw and a threaded sleeve. One end of the screw is connected to a block, one end of the threaded sleeve is rotatably connected to another block, and the other end of the screw is screwed into the other end of the threaded sleeve.

[0014] This invention provides a construction method for a bottom formwork reinforcement device for the upper support pier of a seismic isolation bearing, comprising the following steps:

[0015] Install seismic isolation bearings on the lower support pier;

[0016] The rectangular sleeve holes of the two support components are respectively fitted onto the top and bottom of the seismic isolation bearing, and the support plate of the support component at the bottom of the seismic isolation bearing is laid on the lower support pier.

[0017] Multiple support components are spaced apart along the circumferential direction of the rectangular sleeve hole, such that the support components are positioned between the opposite sides of the support plates of the two support components.

[0018] Adjust the length of the support rod of the support assembly so that the support assembly is supported between the opposite sides of the support plates of the two support assemblies so that the support plate of the support assembly at the top of the seismic isolation bearing is flush with the top of the seismic isolation bearing.

[0019] Concrete for the upper support pier is poured onto the support plate of the support assembly at the top of the seismic isolation bearing to solidify and form the upper support pier.

[0020] The beneficial effect of this invention is that, before use, the bottom formwork reinforcement device for the upper support pier of the seismic isolation bearing selects support plates of different lengths and widths according to different types of seismic isolation bearings. After the seismic isolation bearing is installed, the support plate with the steel pier is first locked onto the lower plate of the seismic isolation bearing through a sliding groove, and then the support rod is connected to install the top support plate of the seismic isolation bearing. The support rod is adjusted so that the top support plate of the seismic isolation bearing is at the design elevation. After installation, the upper concrete can be poured. During dismantling, the support rod is shortened, and the component consisting of the support rod, support plate, support plate, and pier block is slid and dismantled along the sliding groove.

[0021] The bottom formwork reinforcement device for the upper support pier of the seismic isolation bearing of the present invention perfectly solves the problem of bottom formwork support for the upper support pier of the seismic isolation bearing, and the structural concrete forming effect is good.

[0022] The bottom formwork reinforcement device for the upper support pier of the seismic isolation bearing of the present invention is simple to operate, requires only one person to construct, and the splicing method is easy to construct.

[0023] The bottom formwork reinforcement device of the upper support pier of the seismic isolation bearing of the present invention can be reused multiple times, reducing construction costs.

[0036] In this embodiment, the groove opening of the slide 110 extends in opposite directions to form an anti-detachment lip plate. Limiting blocks are formed on opposite sides of the slider. The limiting blocks abut against the inner side of the anti-detachment lip plate. The limiting blocks are disposed on the side of the slider away from the support plate, and the limiting blocks and the slider are T-shaped.

[0037] In some embodiments, the width of the groove 110 gradually decreases from the bottom of the groove 110 toward the opening of the groove 110. The cross-section of the slider is adapted to the cross-section of the groove 110.

[0038] In this embodiment, the support assembly 2 includes two blocks 21 and an adjustable-length support rod 22. The support rod 22 is connected to the two blocks 21. The support assembly 2 is supported between the opposite sides of the support plates 11 of the two support assemblies 1.
