Problems solved by technology

When opening or closing the door leaf, it is realized by operating two handles in sequence, and the weight of the civil air defense door can reach 1 ton. Operating the two handles in turn leads to manual operation difficulties, and it is easy to cause loosening of the contact parts of the door leaf and the door frame, which is very dangerous for the air defense door. The airtightness has adverse effects

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] See attached Figure 1-15 , The embodiment of the present invention provides a reinforced steel fiber reinforced concrete civil air defense door, which includes: a door frame 300, a door leaf 100, a seal, a single-handle linkage lock and a hinge. The door leaf 100 is formed with a strip groove for accommodating the seal, and the seal can be the seal strip 500; the door leaf 100 is a reinforced steel fiber concrete door leaf, and the material of the main body of the door leaf is reinforced steel fiber concrete at this time, that is, the door leaf is reinforced steel fiber concrete. The door leaf for civil air defense doors, for example, uses steel bars to form the door leaf body, fills the door leaf body with steel fibers, and fi...

Abstract

The invention provides a reinforced steel fiber concrete civil air defense door. The reinforced steel fiber concrete civil air defense door comprises a door frame, a door leaf, sealing parts, a monolever interlock and hinges, wherein the door leaf is a reinforced steel fiber concrete door leaf and hinged to the door frame through the hinges, and the monolever interlock arranged on the door leaf comprises an outer handle and an inner handle which are arranged on the outer side and inner side of the door leaf respectively through a first horizontal rotation mechanism and can rotate around the horizontal axis; a plurality of locks are sequentially arranged on the inner side of the door leaf in the circumferential direction of the door leaf, and each lock rotates around the horizontal axis; a plurality of connecting rods are connected in an end-to-end mode to form a square with one side open and are arranged on the inner side of the door leaf in an integrally moving mode, one of the connecting rods is in rotary connection with the inner handle, and the locks are in rotary connection with the connecting rods correspondingly. The civil air defense door is easy to operate, time and labor are saved, a sealing rubber strip can be uniformly compressed, and reliable sealing is realized.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a reinforced steel fiber concrete civil air defense door suitable for underground protection engineering. Background technique [0002] Underground protective engineering, also called civil air defense fortifications, refers to underground protective buildings built separately to protect personnel and material shelter, civil air defense command, and medical rescue in wartime, as well as basements that can be used for air defense in wartime when combined with ground buildings. The door of the entrance and exit of the underground protection project is called the civil air defense door. Among the many types of civil air defense doors, the reinforced steel fiber reinforced concrete civil air defense door is widely used. The control type of its opening and closing is mainly the manual control type, that is, the civil air defense door is a manual door. [0003] In the prior art, two h...
