Problems solved by technology

[0002] Existing earthquake refuge cabins (facilities) and underground safety cabins include other safety cabins, the core structure of which is composed of a fixed connection between the protection cabin and the main protection structure of the outer layer of the protection cabin; the connection between the protection cabin and the outer main protection structure is It is a hard connection, or a part of the buffer material is covered on the outer protective structure to reduce the impact of heavy objects on the cabin; these protective cabins can only provide protection against objects that are injured, bruised or crushed by objects in the cabin , and when an earthquake occurs, the building collapses, and when the protective cabin falls together with the building, the cabin and the people sitting in the cabin will have a hard collision during the fall process, and the impact of the cabin falling on the people in the cabin cannot be avoided. harm
[0003] In addition, the existing earthquake refuge cabin is built in the building while building the building, and cannot be installed in the building after the building is completed according to the needs of the building.

Embodiment 1

[0028] see Figure 1 to Figure 10 As shown, the earthquake refuge safety cabin includes an outer main protective structure 1 and an inner protective cabin 2, and sixty steel springs are passed between the outer shell of the inner protective cabin 2 and the inner wall of the outer main protective structure 1. 3. Flexible and fixed connection, so that the inner protective cabin 2 is flexibly suspended inside the outer main protective structure 1 .

[0029] The outer main protective structure 1 is a frame structure as a whole, and the frame structure is connected and fixed by metal pipes 11 through bolts.

[0030] Each frame plane of the frame structure is provided with supporting ribs fixedly connected by metal pipes 11 through bolts.

[0031] The cross-section of the inner protection cabin 2 is oval, and the inner protection cabin 2 is composed of left and right halves 21, 22, and the left and right halves 21, 22 are butted and connected by bolts. The bulkhead of cabin 2 is m...

Embodiment 2

[0039] The elastic component 3 is a pneumatic shock absorber.

[0040] The earthquake refuge safety cabin is different from Embodiment 1 in that the bulkhead material of the inner protective cabin 2 is a pressure-resistant polyimide material.

[0041] The material of the flame retardant and heat insulating material layer 23 is asbestos material; the material of the flame retardant protective material layer 24 is a flame retardant rubber foam material.

[0042] The outer surface of the overall frame structure of the outer main body protection structure 1 is covered with an outer protective thin plate 13 fixed with pressure-resistant polyimide.

Embodiment 3

[0044] The elastic component 3 is a hydraulic shock absorber.

[0045] The earthquake refuge safety cabin differs from Embodiment 1 in that the bulkhead material of the inner protection cabin 2 is a 25CrMo4 steel plate.

[0046] The flame retardant and heat insulating material layer 23 is made of asbestos material; the flame retardant protective material layer 24 is made of flame retardant plastic foam material.

[0047] The outer surface of the overall frame structure of the outer main protective structure 1 is covered with an outer protective thin plate 13 fixed with a 25CrMo4 steel plate.

Abstract

The invention relates to a safety cabin for earthquake refuge. The safety cabin comprises an outer layer main body protection structure body and an inner layer protection cabin. A casing of the inner layer protection cabin and the inner wall of the outer layer main body protection structure body are flexibly and fixedly connected through an elastic part to enable the inner layer protection cabin to be hung in the outer layer main body protection structure body. The safety cabin is capable of avoiding smashing, extruding, pressing and burying damages to personnel in the safety cabin by collapsed heavy objects of a building, has the anti-falling capability, and reduces impact damage to the personnel caused by falling, has the functions of resisting fire hazards and alarming. The safety cabin is convenient to transport and combine and install in a built building due to the detachable structure.
