Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an isolation layer rubber bearing support protection assembled construction device. Background Art

[0002] After the rubber bearing of the seismic isolation layer is installed, in order to ensure that the pier maintains the correct shape and size during the subsequent construction process, it is usually necessary to support it with a circle of formwork around the flange plate of the pier on the rubber bearing. At the same time, in order to maintain the stability of the performance of the rubber bearing, it is usually necessary to perform fire-resistant sealing and moisture-proof treatment on the rubber bearing. In order to facilitate the template installation and fire-resistant sealing and moisture-proof treatment of the rubber bearing, the staff usually use prefabricated construction equipment. The existing prefabricated construction equipment is usually composed of upper insulation profiles, insulation substrates, steel keels, nuts, and lower insulation profiles.

[0003] For example: the invention patent with application number CN201710254966.1 discloses a fire protection device for a building seismic isolation rubber bearing and its construction method, which specifically includes an upper insulation profile, a lower insulation profile, an aluminum silicate fiber felt, a connector and a fireproof sealing material, wherein two upper insulation profiles are installed on the seismic isolation rubber bearing through a connecting device, a fireproof sealing material is pasted between the contact surface of the upper insulation profile and the upper column, the lower insulation profile is built on the top surface of the lower column with fireproof glue, the fireproof sealing material is pasted between the upper insulation profile and the lower insulation profile, and the gap between the upper insulation profile and the lower insulation profile and the seismic isolation rubber bearing is filled with aluminum silicate fiber felt. By using this fire protection construction method, good fire protection for the seismic isolation rubber bearing can be achieved, and it can be ensured that the fire protection is not destroyed when the seismic isolation bearing is deformed. At the same time, this method has the advantages of easy operation and a wide range of applications.

[0004] However, the existing seismic isolation layer rubber bearings are usually constructed step by step during formwork support, fire-resistant sealing and moisture-proof treatment, which means that each step requires separate construction time and labor arrangements, and the overall construction period will be relatively long. At the same time, after the formwork support is installed, it will occupy a certain space, making the operating space for fire-resistant sealing and moisture-proof treatment narrow, affecting the installation efficiency of fire-resistant sealing and moisture-proof treatment, and is inconvenient to use. Summary of the invention

[0005] In view of this, the present invention provides a seismic isolation layer rubber bearing support protection assembled construction device, which has a fire-resistant composite board that can install fire-resistant sealing and moisture-proof treatment together with the formwork support. During the installation of the fire-resistant composite board, as the fire-resistant composite board approaches the rubber bearing body, the supporting steel plate will attract the magnetic block, and the fire-resistant composite board will be adsorbed onto the rubber bearing body under the magnetic attraction of the magnetic block itself, so as to position and preliminarily fix the fire-resistant composite board. When the fire-resistant composite board is adsorbed onto the rubber bearing body, the fixed card block will be squeezed, so that the fixed card block slides in the auxiliary support block and squeezes the fixed spring. When the fire-resistant composite board is completely adsorbed onto the rubber bearing body, the fixed card block will be reset along with the elastic potential energy of the fixed spring itself and inserted into the fixed card slot to limit and fix the fire-resistant composite board.

[0010] Furthermore, each of the four groups of fire-resistant composite panels is provided with a fire-proof blocking telescopic panel; each of the four groups of fire-resistant composite panels is provided with a group of telescopic panel fixing angle steels on the inner side; and the four groups of telescopic panel fixing angle steels are respectively aligned with the positions of the four fire-proof blocking telescopic panels.

[0011] Furthermore, one side of the four groups of auxiliary connecting blocks is provided with a group of locking buckles; the other sides of the four groups of auxiliary connecting blocks are slidably connected with a group of locking blocks; the inner sides of the four groups of locking blocks are fixedly connected with a group of connecting springs; the ends of the four groups of connecting springs are respectively fixedly connected in the four groups of auxiliary connecting blocks.

[0012] Furthermore, each of the four groups of auxiliary support blocks is slidably connected to a group of fixed blocks; each of the four groups of fixed blocks is fixedly connected to a group of fixed springs on the inner side; the ends of the four groups of fixed springs are respectively fixedly connected to the four groups of auxiliary support blocks; and the four groups of fixed blocks are respectively inserted into the four groups of fixed slots.

[0014] Beneficial Effects

[0015] During the installation of the fire-resistant composite board, the fire-resistant composite board can be positioned during the installation process by the cooperation between the installation slider and the installation guide rail. After the installation slider is placed in the installation guide rail, the fire-resistant composite board is gently pushed. As the fire-resistant composite board approaches the rubber support body, the support steel plate will attract the magnetic block. Under the magnetic attraction of the magnetic block itself, the fire-resistant composite board is adsorbed onto the rubber support body, so that the fire-resistant composite board is positioned and preliminarily fixed. At the same time, when the fire-resistant composite board is adsorbed onto the rubber support body, the fixed card block will be squeezed. When the fire-resistant composite board is completely adsorbed onto the rubber support body, the fixed card block will move with the fixing spring itself. The elastic potential energy is reset and inserted into the fixed card slot to limit and fix the fire-resistant composite board, so that the formwork support and protective sealing of the rubber bearing can be integrated into the construction, and the narrow space operation can be completed in advance, which not only saves material transportation costs, but also improves the construction efficiency of operators. At the same time, the installation and disassembly process of the fire-resistant composite board becomes very simple through the magnetic attraction and fixed card block fixation. When the rubber bearing needs to be maintained or inspected, the fire-resistant composite board can also be easily disassembled without causing damage to the rubber bearing itself or the surrounding structure, which effectively improves the practicality and convenience of the seismic isolation layer rubber bearing support protection prefabricated construction device.

[0016] When the fire-resistant composite panels are successively adsorbed onto the main body of the rubber bearing, the locking buckle will squeeze the locking block as the fire-resistant composite panels contact each other. When the fire-resistant composite panels are fully in contact, the locking block will rebound and be inserted into the locking buckle under the action of the elastic potential energy of the connecting spring, so that the fire-resistant composite panels around the main body of the rubber bearing are fixed to each other, increasing the stability of the entire structure. When subjected to external forces, the composite panels fixed together are not easy to shift or disperse. They can resist external forces as a whole, thereby better protecting the rubber bearing. At the same time, the mutual fixation also helps to ensure the sealing effect between the composite panels, effectively improving the stability and sealing of the rubber bearing support protection assembly construction device of the seismic isolation layer.
