Abstract
The utility model relates to a guard gate of tunnel equipment hole room and passway for escaping. The operation of high -speed motor car can be faced each other to personally experience sth. Part of the body to produce and drawn the reversal loading of pressure in the tunnel, and the intensity of the body that faces each other has higher requirement. The utility model discloses in the tunnel inside the upper portion level transversely set up the girder, the tunnel wall body is fixed in through the pan bolt in the girder both ends, girder below both sides are provided with a body, and door body apical margin is fixed in the girder through the pan bolt, and the lateral margin is fixed in the tunnel wall body through the pan bolt, be provided with two door leafs between the door body of both sides, the door leaf lateral margin passes through the hinge mount on the door body, be connected with the chain between the adjacent door leaf of men tiyu, it is fixed with the obliquely backup pad to connect between the men tiyu tunnel wall body. The utility model discloses safe and reliable, most load of bearing a body by the girder, convenient operation, laborsaving reduces to open the operation strength that the door latch closed greatly, and just the door body adopts the piecemeal welding to form, the installation of being convenient for.
Description
Technical field
The utility model relates to a kind of tunnel protection door, is specifically related to the protective door of a kind of tunnel device cavern and passway for escaping.
Background technology
Along with developing rapidly of China's transport development, the tunnel quantity of railway, highway, city underground gets more and more, its length is also more and more longer, due to the space that tunnel is a relative closure, must interconnection protective door be set in tunnel, when breaking out of fire and explosion accident, personnel enter place of safety by protective door, thus the safety of support personnel and driving, in order to win enough egress times, protective door must have good fireproof performance and resist the ability of explosion wave.In tunnel, the operation meeting opposite house body of high speed motor car produces the fluctuating load effect of tension and compression, and the intensity of opposite house body has higher requirement.General protective door structure size is comparatively large, and by the restriction of transport with mounting condition, protective door piecemeal manufacture in factory usually, it is shaping that welding is carried out at scene.In tunnel, condition of work is relatively more severe, and welding quality can be caused effectively to check and to ensure.The uprising fire resistance property of existing protective door is poor, and door body is heavy, inconvenient artificial unlatching or closedown, and installs inconvenience., there is door leaf case accident in door body poor welding quality.
Summary of the invention
The purpose of this utility model is to provide the protective door of a kind of tunnel device cavern and passway for escaping, and the welding quality existed in solution prior art cannot ensure, door body is heavy, inconvenient problem such as manually unlatching or closedown etc.
The technical scheme that the utility model adopts is:
A protective door for tunnel device cavern and passway for escaping, is characterized in that:
In tunnel, middle and upper part horizontal cross arranges girder, and tunnel body of wall is fixed on by pan bolt in girder two ends;
Below girder, both sides are provided with a body, and door body apical margin is fixed on girder by pan bolt, and lateral margin is fixed on tunnel body of wall by pan bolt;
Be provided with two fan door leafs between two side door bodies, door leaf lateral margin is arranged on a body by hinge;
Chain is connected with between the adjacent door leaf of Men Tiyu;
Oblique gripper shoe is fixedly connected with between Men Tiyu tunnel body of wall.
Door body adopts fraction block structure, is formed by the welding of polylith unit board.
Two fan door leafs are hingedly provided with bolt.
The utility model has the following advantages:
1. safe and reliable:
The utility model adopts main beam stress mode, and door body has weldless body pillar, is connected with door body, and girder bears most load of a body, and the piece bearing load hardly of point block welding, due to body pillar no-welding-seam, so bearing load ability is large; Door body adopts traverse latch structure, and bear the load of door leaf, bolt is Integral cross beam, and supporting capacity is large.
2. manual operation is convenient, flexible, laborsaving:
Bolt is hinged on door leaf, can rotate with door leaf, and operating personnel only need the gravitational difference overcoming hinge both sides bolt door leaf just can be made to open or close, and the operation strength that bolt closes is opened in reduction greatly.
3. easy for installation:
Because door body adopts piecemeal welding to form, thus manufacture, transport, easy for installation.
Accompanying drawing explanation
Fig. 1 is the utility model elevation.
Fig. 2 is gripper shoe scheme of installation.
In figure, 1-girder, 2-door body, 3-door leaf, 4-bolt, 5-chain, 6-gripper shoe, 7-pan bolt.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The utility model relates to the protective door of a kind of tunnel device cavern and passway for escaping, and in tunnel, middle and upper part horizontal cross arranges girder 1, integrated welding seam-free, bears most load of a body.Tunnel body of wall is fixed on by pan bolt 7 in girder 1 two ends.Below girder 1, both sides are provided with a body 2, and door body 2 apical margin is fixed on girder 1 by pan bolt 7, and lateral margin is fixed on tunnel body of wall by pan bolt 7.Be provided with two fan door leafs 3 between two side door bodies 2, door leaf 3 lateral margin is arranged on a body 2 by hinge.Be connected with chain 5 between door body 2 and adjacent door leaf 3, under preventing fortuitous event, door leaf 3 comes off, and swings to rail.Be fixedly connected with oblique gripper shoe 6 between door body 2 and tunnel body of wall, play reinforced door body.Two fan door leafs 3 are hingedly provided with bolt 4, and can rotate with door leaf, be Integral cross beam, supporting capacity is large.
Door body 2 adopts fraction block structure, is formed, bearing load hardly by the welding of polylith unit board.Also the unit board for covering is provided with above girder 1 and between tunnel body of wall.
Protective door fire endurance is not less than 3 hours, and uprising load is not less than 0.05MPa/m2, and maximum positive and negative air-pressure is+8 ~-12Kpa.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model manual to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
