The cold storage with splicing structure has the advantages of prefabricated wall panels, fast construction, and low cost. The splicing cold storage structure usually includes a cold storage base, side panels, and top panels. The side panels not only play a role in insulation but also play a supporting role. The prefabricated block-shaped wall panels are connected together through a wall panel connection structure to form a cold storage wall. The top panel is fixedly installed on the top of the wall, thus forming a closed cold storage space.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the implementation mode of the utility model will be further described below in conjunction with the accompanying drawings.

[0023] Please refer to Figures 1 to 3 A cold storage wall panel connection device comprises a fixed bottom plate 2, a connecting column 3, two insulation wall panels 4 and a plurality of connecting parts.

[0024] The cold storage base 1 is made of reinforced concrete. The cold storage base 1 is cast on the ground or floor of the building. The fixed bottom plate 2 is fixed on the cold storage base 1, and the fixed bottom plate 2 is a strip plate; the lower end of the connecting column 3 is fixed on the fixed bottom plate 2. In this embodiment, the fixed bottom plate 2 and the connecting column 3 are both made of steel. The fixed bottom plate 2 is a steel plate. The bottom of the connecting column 3 is welded to the fixed bottom plate 2, and the fixed bottom plate 2 is fixed to the cold storage base by a plurality of expansion bolts or a plurality of embedded screws.

[0025] The two insulation wall panels 4 are arranged adjacent to each other, and the two insulation wall panels 4 are located on both sides of the connecting column 3, and the insulation wall panels 4 are supported on the fixed bottom plate 2; the connecting column 3 includes a column body and two connecting wing plate groups, and the column body is a hollow rectangular steel column structure. The two connecting wing plate groups are respectively connected to the two side surfaces of the column 3, and each connecting wing plate group includes two parallel connecting wing plates 32, and a connecting slot is formed between the two connecting wing plates 32 of each connecting wing plate group.

[0026] The edges of the two insulation wall panels 4 are respectively limited in the two connection slots, and a plurality of connection holes are provided on the edges of the insulation wall panels 4 and the connection wing plates 32. The connection member passes through the connection holes on the insulation wall panels 4 and the connection wing plates, and the two insulation wall panels 4 are locked in the two connection slots. In this embodiment, the connection member is a connection bolt 6.

[0027] In the above structure, the connecting wing plate of the connecting column 3 can firmly connect the adjacent insulation wall panel, and the connecting device connecting the column and the fixed bottom plate can transfer the load on the insulation wall panel to the cold storage base. The connecting device can greatly improve the ability of the cold storage wall to resist lateral force, thereby improving the structural strength of the cold storage wall.

[0028] Preferably, a limit strip 21 with an upper protrusion is provided in the middle of the fixed base plate 2, and a positioning groove is provided at the bottom of the thermal insulation wall panel 4. The limit strip 21 is inserted into the positioning groove. The matching structure of the limit strip 21 and the positioning groove can simultaneously improve the connection accuracy of the thermal insulation wall panel and reduce the installation difficulty of the high thermal insulation wall panel.

[0029] Furthermore, the column body is filled with a heat-insulating filler 31, which is a polyurethane foam. The heat-insulating filler 31 is filled in the column body to improve the heat-insulating capacity of the column body and prevent the cold air in the cold storage from overflowing due to the heat conductivity of the column body.

[0030] Preferably, an inner column 5 is further provided in the column body, and the lower end of the inner column 5 is fixed to the fixed bottom plate 2. A connection cover 51 is provided on the top of the column body, and a welding hole is provided in the middle of the connection cover 51.

The edge of the connection cover 51 is welded to the column body. The connection cover 51 is used to connect the inner column 5 and the column body into an integral structure, so that the connection column 3 forms an inner and outer double column structure. The inner and outer double column structure of the connection column 3 can further improve the structural strength of the connection column 3.

A second sealing gasket 71 is provided on the surface of the clamping plate 7, and the second sealing gasket 71 is located between the clamping plate 7 and the insulation wall panel 4. In this embodiment, the first sealing gasket 33 and the second sealing gasket 71 are both made of rubber, and the elastic member is a coil spring 8. The two first sealing gaskets 33 clamp the insulation wall panel 4 under the tightening force of the connecting bolts, and the second sealing gasket 71 can compress the insulation wall panel 4 under the elastic force of the coil spring 8, which can greatly improve the sealing of the cold storage wall and the insulation capacity of the cold storage. At the same time, the elastic force of the coil spring 8 can make the second sealing gasket 71 flexibly connected to the insulation wall panel 4. When the cold storage wall vibrates and is subjected to impact force, the coil spring 8 can compensate for the connection gap of the insulation wall panel to prevent the connection structure between the wall panels of the cold storage wall from loosening, thereby further improving the impact resistance of the cold storage wall.
