Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and in particular to a prefabricated earthquake-resistant structure. Background Art

[0002] Prefabricated buildings refer to buildings assembled on site using prefabricated components. By splitting the designed building structure into prefabricated components and prefabricating the split prefabricated components, the prefabricated components only need to be assembled according to the design drawings during the construction of the prefabricated building, which can comprehensively improve the building quality and construction efficiency. And with the continuous improvement of design capabilities and the production level of prefabricated components, the design, component splitting and assembly effects of prefabricated buildings have been greatly improved, and prefabricated buildings have gradually been widely used.

[0003] The steel bar connections between different prefabricated components of prefabricated buildings are often based on offset welding or simple sleeve connections. This type of connection method has the problem of low coaxiality due to the contact misalignment of the two sections of steel bars. In actual use, vibration waves often need to transfer energy outward based on vertical bars. When the coaxiality of the vertical bars is low, it is difficult for the vibration energy to be actually transmitted and dissipated, causing the vibration to be reflected and transmitted in the building body, increasing the probability of concrete damage.

[0004] For example, patent CN109441017A discloses a dry-type steel bar connector for prefabricated buildings, including a vertical plate arranged along the vertical direction, several groups of first transverse plates fixed to the left side of the vertical plate, and a second transverse plate fixed to the right side of the vertical plate and corresponding to each group of first transverse plates. The first transverse plate is located in the prefabrication area of ​​the dry-type steel bar connector, and the second transverse plate is located in the post-supplement area of ​​the dry-type steel bar connector. Through holes are provided in the first transverse plate and the second transverse plate. The steel bars of the prefabricated components in the prefabrication area are passed through the through holes of the first transverse plate, and the steel bars of the prefabricated components in the post-supplement area are passed through the through holes of the second transverse plate, and both are fastened by nuts.

[0005] The above technical solution adopts offset installation, which makes it difficult to actually conduct vibration waves and achieve earthquake resistance.

[0006] A prefabricated earthquake-resistant structure is now needed to solve the above problems. Summary of the invention

[0007] The present invention aims to solve the problem that the steel bar connection between different prefabricated components of prefabricated buildings in the prior art is often based on offset welding or simple sleeve connection. Such connection methods have the problem of low coaxiality due to the contact misalignment of two sections of steel bars. In actual use, vibration waves often need to transfer energy outward based on vertical bars. When the coaxiality of the vertical bars is low, it is difficult for the vibration energy to be substantially transmitted and dissipated, causing the vibration to be reflected and transmitted in the building body, resulting in an increased probability of concrete damage. An assembled seismic-resistant structure is provided to solve the above problem.

[0008] The present invention provides an assembled earthquake-resistant structure, comprising a first assembly component body, a second assembly component body, connecting bars, a socket mechanism, a grouting hole and a correction and plugging mechanism, wherein the connecting bars are vertically arranged on the first assembly component body, the socket mechanism is a countersunk mechanism, which is arranged on the end face of the second assembly component body, the first assembly component body and the second assembly component body are matched by the connecting bars and the socket mechanism and connected by filling concrete for curing, the grouting hole is arranged on the side of the second assembly component and connected to the inner cavity of the socket mechanism, a steel bar with an end protruding out of the inner bottom surface of the socket structure is arranged in the second assembly component body, the steel bar is coaxially connected with the connecting bars, the correction and plugging mechanism is arranged in the socket mechanism, the correction and plugging mechanism is a sleeve connecting the connecting bars and the steel bars in the socket mechanism, and the correction and plugging mechanism plugs the grouting hole when the steel bar and the connecting bars are not coaxial.

[0009] The assembled seismic-resistant structure described in the present invention, as a preferred embodiment, the correction and plugging mechanism includes a sleeve, a first guide port, a second guide port, a grouting bell mouth, a flow channel, a first connecting sleeve, a second connecting sleeve and a plugging cover, the plugging cover is a charged capacitor with a micro-magnetic cover body on one side, the charged capacitor and the micro-magnetic cover body are electrically connected to the first connecting sleeve and the second connecting sleeve at both ends, the micro-magnetic cover body is magnetically adsorbed on the two connecting ends inside the grouting bell mouth, the current direction of the charged capacitor is opposite to the magnetic direction of the micro-magnetic cover body, the first connecting sleeve and the second connecting sleeve are both conductors, the first guide port and the second guide port are coaxial and connected bell mouth structures, the first guide port and the second guide port are arranged inside the sleeve and penetrate the sleeve, the sleeve is a cylindrical sleeve arranged in a socket mechanism, the first connecting sleeve is arranged in the first guide port and connected to the end of the steel bar, the second connecting sleeve is arranged in the second guide port and connected to the end of the connecting bar, the grouting bell mouth is arranged on one side of the sleeve body to connect the grouting port and the first guide port and the second guide port, the flow channel is arranged in the sleeve body to vertically connect the two ends of the sleeve body and pass through the grouting bell mouth.

[0010] The flow channel is provided to make it easier to fill the socket mechanism when concrete is filled.

[0011] In the assembled earthquake-resistant structure described in the present invention, as a preferred embodiment, the inner surface of the first connecting sleeve and the inner surface of the second connecting sleeve are both provided with a buffer structure, and the buffer structure is made of elastic material.

[0012] In the assembled earthquake-resistant structure described in the present invention, as a preferred embodiment, both the first connecting sleeve and the second connecting sleeve are made of permanent magnets.

[0013] The use of permanent magnets makes the contact closer, avoids the problem of separation after a light touch, and facilitates the rapid positioning of the two.

[0014] The assembled earthquake-resistant structure described in the present invention is preferably provided with a connected and destructible brittle shell on the inner wall of the first connecting sleeve, the inner wall of the second connecting sleeve and the contact position of the middle opening of the first connecting sleeve and the second connecting sleeve, and air-curing material is provided in the brittle shell.

[0015] The use of solidified materials for connection can achieve further energy absorption through elasticity while avoiding the problem of uneven fracture at the steel bar joint.

[0016] The beneficial effects of the present invention are as follows: The two connecting sleeves used in this device cooperate with the capacitor and magnet connected in parallel. When the capacitor and the connecting sleeve are connected, it is called a complete circuit, and the contact area of ​​the connecting sleeve is sufficient, that is, when the ends of the two connecting sleeves are completely in contact, the capacitor discharges, the magnet is demagnetized, and the grouting port is opened; at the same time, the physical condition for the two connecting sleeve ends to be completely in contact is that the heads of the steel bars wrapped by the two connecting sleeves are coaxial in the contact section, so that the vibration wave is effectively transmitted vertically, avoiding the vibration wave from oscillating in the building and causing damage.
