Description

Anti-deformation door body structure Technical Field The utility model relates to the technical field of door bodies, in particular to an anti-deformation door body structure. Background The door is a building entrance and exit, and means a device installed at the entrance and exit to be opened and closed. The existing doors are of various varieties, such as aluminum alloy doors, wooden doors, bamboo doors and the like. The door is generally constructed of a door frame and a facing plate disposed in the door frame. The traditional layered door body mostly adopts multilayer composite structures such as an outer decorative layer, a core layer, a reinforcing layer and the like so as to achieve both strength and functionality. In the existing door body, each interlayer is weak in mechanical connection, each structural layer of the conventional layered door body is usually bonded by an adhesive or fixed by local screws, penetration rigid connection is lacking among layers, interlayer peeling is easy to occur under the effect of temperature and humidity circulation, and the joints are easy to crack under the impact of frequently opening and closing the door due to the lack of special reinforcing structures in four corner areas, so that the whole structure is unstable. Disclosure of utility model The utility model aims to solve the problems of stripping and cracking at four corners of the existing door body structure and provides a deformation-resistant door body structure. An anti-deformation door structure, comprising The four corners of the outer layer are provided with upright posts, and the middle parts of the upright posts are provided with threaded holes; The core layer is positioned at the inner side of the outer layer, and four corners of the core layer are provided with first through holes; The reinforcing layers are arranged on two sides of the core layer and are respectively a first reinforcing layer and a second reinforcing layer, and second through holes are formed in four corners of the reinforcing layers; the inner layer is arranged on the inner side of the second enhancement layer, round grooves are formed in four corners of the inner layer, and third through holes are formed in the round grooves in a penetrating mode. Further, the core layer comprises an aluminum core substrate, honeycomb partition plates are sequentially arranged on the inner surface and the outer surface of the aluminum core substrate in an array mode, and polyurethane foaming materials are filled in the honeycomb partition plates.
