Technical field

The present invention relates to civil air defense constructions and installations apparatus field, in particular to a kind of civil air defense constructions and installations shock resistance composite protective door.

Background technique

Protection works oral area is weak link and the key point strike position of engineering, and underground protective engineering carries protection Internal staff, equipment safety important duty, therefore protective door is as the most important safeguard of oral area, to ensureing civil air defense constructions and installations General safety there is decisive role, thus be always the key content of protection works research.

Existing protective door mostly uses Reinforced Concrete Materials, and door body generallys use plain batton door or arched door.Because of protection Door drag grade usually require that it is very high, so armored concrete mechanism door body needs make it is very thick very heavy, production plus Work, transport installation are all relatively difficult.

Summary of the invention

More heavy, the relatively difficult problem of processing and installation, mesh of the invention for protective door of the existing technology Be a kind of civil air defense constructions and installations shock resistance composite protective door is provided.

To achieve the above object, the technical solution of the present invention is as follows:

A kind of civil air defense constructions and installations shock resistance composite protective door, including door body and doorframe, the door body include outer layer arch sheet And it is connected to the internal layer plate on the outer layer arch sheet inner wall, have between the internal layer plate and the outer layer arch sheet Cavity, the cavity is interior to be equipped with filled layer, and the filled layer includes honeycomb skeleton and is filled in the honeycomb skeleton Packing material, the packing material be one of sandy soil, concrete, polyurethane or several, the outer layer arch sheet, institute The material for stating internal layer plate is steel or glass fiber reinforced plastics composite material.

Preferably, the honeycomb skeleton includes the sub-honeycomb skeleton of at least two-layer laminate setting, two adjacent sub- bees The honeycomb hole of nest skeleton is staggered.

Further, partition is equipped between the adjacent two sub-honeycomb skeletons.

Preferably, the internal layer plate and outer layer arch sheet junction are inclined surface, and the inclined surface is from the door The outside of body is tilted to the center of interior lateral door body.

Further, the inner wall of the outer layer arch sheet is equipped with deep floor.

By adopting the above technical scheme, due to the setting of the outer layer arch sheet of arc, enable external shock wave fast Speed is diverted to outside door body, so that the impact force or shock wave that door body receives be effectively reduced；In the intracorporal cavity of door and cavity The setting of the honeycomb skeleton of setting has heat-insulated and isolation shock wave so that the structural strength of door body and rigidity are more superior Effect；The setting of packing material in honeycomb skeleton so that shock wave through after outer layer arch sheet, can make packing material into The rapid decay of one step, the safety inside limited protection civil air defense constructions and installations.

Detailed description of the invention

Fig. 1 is the structural diagram of the present invention；

Fig. 2 is the connection schematic diagram of China and foreign countries' layer arch sheet and deep floor of the present invention.

In figure: 1- door body, 11- outer layer arch sheet, 12- internal layer plate, 13- sub-honeycomb skeleton, 14- partition, 15- ribs Plate, 2- doorframe, 3- pedestal, 4- shaft, 5- attachment base.

Specific embodiment

Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.

As shown in Figure 1, a kind of civil air defense constructions and installations shock resistance composite protective door, including door body 1 and doorframe 2, door body 1 and doorframe 2 are flexibly connected, and the present embodiment is preferably hinged, specifically, it is provided with pedestal 3 on doorframe 2 or the wall of civil air defense constructions and installations, It is provided with shaft 4 on pedestal 3, is equipped with attachment base 5 in door body 1 accordingly, is provided on attachment base 5 compatible with shaft 4 Axis hole (not shown).

In the present embodiment, door body 1 includes that outer layer arch sheet 11 and the internal layer being connected on 11 inner wall of outer layer arch sheet are flat Plate 12 has cavity, is equipped with filled layer in cavity, filled layer includes honeycomb bone between internal layer plate 12 and outer layer arch sheet 11 Frame and it is filled in the intraskeletal packing material of honeycomb, packing material is one of sandy soil, concrete, polyurethane or several Kind, outer layer arch sheet 11, internal layer plate 12 material be steel or glass fiber reinforced plastics composite material.

In the present embodiment, honeycomb skeleton includes the sub-honeycomb skeleton 13 of at least two-layer laminate setting, two adjacent sons The honeycomb hole of honeycomb skeleton 13 is staggered, meanwhile, partition 14 is equipped between two adjacent sub-honeycomb skeletons 13；Specifically, sub Honeycomb skeleton 13 is arranged according to the axial direction of its honeycomb hole direction parallel with 1 inward-outward direction of door body.

In the present embodiment, internal layer plate 12 and 11 junction of outer layer arch sheet are inclined surface, and inclined surface is from the outside of door body 1 It is tilted to the center of interior lateral door body 1, meanwhile, plane passes through the axis of outer layer arch sheet 11 where the inclined surface；So set, So that external force effectively can be passed to doorframe 2 along arcuate part after 1 stress of door body, until wall is passed to, to make The advantages of external force distribution matches with the shape of door body 1, makes full use of the arcuate in shape of outer layer arch sheet 11.

In the present embodiment, the inner wall of outer layer arch sheet 11 is equipped with deep floor 15, as shown in Fig. 2, deep floor 15 is It is arranged according to its length direction along the radian direction of outer layer arch sheet 11, so can preferably maintain outer layer arch sheet 11 Arch radian, improve door body 1 impact strength.

In use, shock wave is most of first to be intercepted by outer layer arch sheet 11, shunts, few after in external impacts to door body 1 Part is stopped by multilayer sub-honeycomb skeleton 13 and its internal packing material filled again through the impact force of outer layer arch sheet 11, The setting for the multilayer sub-honeycomb skeleton 13 that honeycomb hole mutually staggers simultaneously, additionally it is possible to further disperse shock wave in filled layer It comes, reduces shock wave and door body 1 is caused to concentrate damage.

In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
