Abstract
The utility model provides a high-strength protective door. The protective door comprises a framework and circular arc protective surface layers, wherein the framework is in the form of a plurality of vertical and horizontal grids; the circular arc protective surface layers are arranged in the grids; the protective surface layer in a single grid is shaped like a small semicircle and embedded in the grid of the framework; the whole protective surface layers are integrally connected with each other to form a whole body; the interiors of the protective surface layers are supported by the framework; and adhesive materials are filled in the protective surface layers; if the surface of the protective door suffers an impact force, the impact forces of the protective surface layers can be transmitted to the framework in the grids through the circular arc protective surface layers, and the impact resistance of the arc surface is much higher than the strength of a plate type structure; therefore, the high-strength protective door provided by the utility model obtains high-strength impact resistance and can be used for vulnerable places, such as headquarters, aircraft shelters and so on.
Description
Technical field
The utility model relates to protective door, especially protective door structure.
Background technology
Protective door has manual closed and motorized motions according to driving branch; According to the function branch automatically controlled airtight blast door, automatically controlled sealed door, automatically controlled airtight shield door and automatically controlled protective door are arranged; Waterproof protective door etc.; Shield door has the radioactive contamination of prevention, engineering inside and two kinds of functions of tempest are infiltrated in biological and chemical war agent, and the waterproof protective door can be used for the higher subway place of water level.
But mostly present protective door is plate armature, and the anti-strike capability when hitting for the bigger or bomb of impact force like this is lower.After meeting high-strength impact, the door easy deformation is not easy to open, the escape when influence leaving behind all clear and capturing with inside.
Summary of the invention
The utility model provides a kind of anti-impact force than higher protective door structure.
Technical scheme is following:
The high-intensity protective door is characterized in that protective door is made up of the protection top layer of circular arc in the skeleton of a plurality of grid types in length and breadth and the grid, and single lattice protection top layer is that smaller part is circular; Be embedded in the grid of skeleton; The whole protection top layer connects into integral body, and is inner by the skeleton support, the inner binding material of filling.
If withstand shocks power on such protective door face; The impact force on its protection top layer can be delivered to through the protection top layer of circular arc on the skeleton in the grid; And the impact resistance of surperficial arc exceeds much than plank frame intensity, has so just possessed the performance of anti-high-strength impact.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein: 1, skeleton; 2, the protection top layer of circular arc.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: protective door is made up of the skeleton 1 of grid type; The protection top layer and the bottom package top layer of inner setting-in circular arc; Inside recharges adhesive cures, constitutes the protection top layer 2 of circular arc, so just possesses than higher impact resistance.
In the practical implementation, a plurality of optimization detail schema are arranged:
1. when no fire protection requirement, the polyurethane foam bonding can be adopted in the inside of protective door.
2. when fire protection requirement being arranged, the inside of protective door can adopt cement to convert kieselguhr foaming bonding.
3. arc arc diameter layer by layer is not suitable for above 1 meter.
The side of the utility model answer the reinforcement type protective door can be used for headquarter, aircraft pen etc. easily under fire the place.
