Description

Technical Field

[0001] The utility model relates to the field of prefabricated buildings, and particularly relates to a shock isolation device for connecting prefabricated building components. Background Art

[0002] Traditional buildings are directly constructed by pouring on the construction site. During the construction process, there will be innocent losses of materials and a large amount of construction waste will be generated. When pouring on site, affected by weather changes such as rain, the production cycle may be extended and the quality of the poured components will also be affected. While prefabricated buildings are precast components produced in factories and then transported to the construction site for direct use, which reduces the manpower requirements and at the same time reduces the labor intensity of construction workers. Since the components of prefabricated buildings are directly transported to the site for assembly after being completed in the production workshop, the construction waste at the construction site is reduced, and the construction progress and the quality of the components can be guaranteed at the same time.

[0003] The construction party for on-site assembly of precast components produced in the precast component factory has very strict requirements for the production accuracy of precast components. Therefore, during the deepening design stage of prefabricated buildings, the collision problem should be fully considered, including the possible collision between components after the precast components are assembled during an earthquake, resulting in serious damage to prefabricated buildings under earthquake action. Therefore, we propose a shock isolation device for connecting prefabricated building components, which will most likely solve the above actual collision problem. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to overcome the above deficiencies and propose a shock isolation device for connecting prefabricated building components.

[0005] To achieve the above purpose, the utility model includes the following steps:

[0006] A shock isolation device for connecting prefabricated building components, characterized in that it includes an arc-shaped stainless steel plate, a perforated stainless steel plate, a complete stainless steel plate, a stainless steel rod, an end stainless steel plate, a device locator and rubber particles; the perforated stainless steel plate is connected to the prefabricated building component through the openings by high-strength bolts; the arc-shaped stainless steel plate is connected to the perforated stainless steel plate by welding; both ends of the stainless steel rod are spot-welded to two perforated stainless steel plates to support the prefabricated building components on both sides; the complete stainless steel plate is connected to the arc-shaped stainless steel plate and the perforated stainless steel plate by welding, so that the entire stainless steel connection device becomes an integral body with only the upper side open; the rubber particles are filled between the two perforated stainless steel plates through the upper side opening; the end stainless steel plate is connected to the complete stainless steel plate and the perforated stainless steel plate by welding.

[0007] Furthermore, the arc-shaped stainless steel plate, perforated stainless steel plate, stainless steel rod, end stainless steel plate, and device locator are all made of 304 stainless steel; the arc-shaped stainless steel plate and the end stainless steel plate have a thickness of 6 mm and a length of 5 cm; the perforated stainless steel plate and the complete stainless steel plate have a thickness of 6 mm, and the length matches that of the prefabricated building component; the rubber particles have a particle size of 1-2 mm.

[0008] Furthermore, the upper arc-shaped slot of the device locator is fitted with the arc-shaped stainless steel plate, and the vertical stainless steel plate is used for transition between the arc-shaped slot in the device locator and the bottom stainless steel plate of the locator.

[0009] Furthermore, the specifications of the high-strength bolts are determined according to the actual engineering design; the perforated stainless steel plate and the prefabricated building component are pre-drilled, and the hole diameter matches the diameter of the high-strength bolts adapted to the actual engineering design.

[0010] Furthermore, the stainless steel rods are arranged in an inclined X-shaped grid between the two perforated stainless steel plates to provide support for the two perforated stainless steel plates.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] (1) By setting the stainless steel plate connection device and the locator between the prefabricated building components, the present utility model enables the accurate positioning and installation of the prefabricated building components, avoiding potential safety hazards caused by installation errors. In addition, the rubber particles filled between the stainless steel connection devices can absorb the energy generated by the collision during the assembly process of the prefabricated building components, preventing the prefabricated building components from being damaged due to collision during the assembly process;

[0013] (2) The stainless steel connection device of the present utility model supports the normal operation of the prefabricated building components during the assembly and normal use stages of the prefabricated building components. When an earthquake occurs, the seismic waves are conducted along the prefabricated building components. When the seismic waves reach the stainless steel connection device, the rubber particles filled inside the connection device can absorb a large amount of seismic wave energy, reducing the possibility of subsequent damage to the prefabricated building components.
