Problems solved by technology

[0003] The roof girder of the civil air defense basement needs to be reinforced during the construction process. The traditional reinforcement and tension devices are mostly fixed structures, resulting in the fact that the reinforcement points of the roof girder cannot be adjusted according to the actual building needs, and there are certain limitations.

Abstract

The invention relates to the technical field of civil air defense basements, and discloses a counter-pulling device for reinforcing a top plate beam of a civil air defense basement. The counter-pulling device comprises the top plate beam and a bearing beam, wherein the bearing beam is perpendicular to the top plate beam, and the top end of the bearing beam is fixedly connected with the bottom of the top plate beam; a fixing block is fixedly connected to the outer side of the bearing beam in a sleeving mode, and the outer section of the fixing block is of an annular structure; screw rods are symmetrically arranged on the upper surface of the fixing block, and the two ends of the screw rods are correspondingly and rotationally connected with the fixing block and the top plate beam through bearing seats; the screw rods are connected with the fixing block through driving assemblies, and matched nuts are connected to the screw rods in a threaded and sleeving mode; and two concentric-square-shaped plates which are symmetrical about the bearing beam are arranged on the top plate beam in a sleeving mode, connecting rods are hinged to the bottoms of the concentric-square-shaped plates, and the two connecting rods are symmetrically arranged. According to the counter-pulling device, reinforcing supporting points of the top plate beam can be conveniently adjusted according to actual building requirements, moreover, a locking function is achieved, and the positions of the reinforcing supporting points are effectively prevented from being changed.

Description

technical field [0001] The invention relates to the technical field of civil air defense basements, in particular to a tensioning device for reinforcing roof beams of civil air defense basements. Background technique [0002] Civil air defense basement is a kind of civil air defense fortification, including outer wall, buffer wall, explosion-proof door, closed wall, protective partition wall, etc. It is mainly used for civil air defense temporary shelter, wartime air defense command center, communication center, shelter, etc.; Some permanent fortifications also have three defense functions. In order to ensure the needs of civil air defense command, communication, and shelter, the basement has a predetermined protective function, and it also has the function of storing food and fresh water in emergencies. [0003] The roof beams of the civil air defense basement need to be reinforced during the construction process. The traditional reinforcement and tension devices are mostl...
