Description
Technical field
The present invention relates to railway tunnel protective door, more particularly to a kind of simple fixed connection structure of railway tunnel protective door.
Background technology
According to《Railway engineering designs fire safety rules》(TB10063-2007) and《Railway tunnel Fire prevention evacuation engineering is set
Count specification》(TB10020-2012), " length 5.0km and above staff in tunnel evacuation mouth and equipment cavern all should set protection
Door ", " railway tunnel transverse passage-way protective door fire integrity is not less than 3h ", " the antiknock lotus of mixed passenger and freight railway tunnel protection door
Carry and be no less than 0.10MPa, the antiknock load of Tunnel of Passenger Dedicated Railway Line protective door is no less than 0.05MPa ".It can be seen that protective door
Condition of work be very severe.In addition, in tunnel, throughout the year dark moist environment and train by when power piston wind
Shock loading, strict high request is proposed to protective door and its fixing device design.The firm degree of protective door fixed structure
It is the premise that the design objectives such as protective door fire prevention, the capability of antidetonance give full play to.
The current country is main to pass through pre-buried lower margin steel plate, scene drilling injecting glue bar planting installation, scene borehole anchorage screw rod
Three kinds of mounting means railway tunnel protective door is mounted on the concrete door opening in tunnel.The first mounting means is needed
Just propose pre-buried requirement in advance at the beginning of Tunnel Design, be adapted to newly built railway tunnel；Second and the third be adapted to tunnel and apply
Installed after the completion of work or to the protective door of existing tunnel, but be required for live perforate.
In actual applications, the extremely difficult accurate implementation of live snap the line locating holes, position of opening, perforate size, perforate depth
Often change because interlocking with door opening inside concrete embedded bar position, cause skew, the hole mistake of actual position of opening
Greatly, the problems such as hole is tilted, hole depth is improper, causes the skew of implantation reinforcing bar or chemical drift bolt screw position, and reduction is glutinous
Knot ability and anti-fatigue performance, and and protective doorframe on fixed installation hole site produce deviation, finally influence tunnel protection
The performance of the fire-proof and explosion-proof interrupting performance in fixed position and protective door of door.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple fixed connection structure of railway tunnel protective door, to have
Effect solves the problem of position of opening and embedded bar position conflict at concrete door opening, reduces site operation installation difficulty.
The technical solution adopted for the present invention to solve the technical problems is as follows：
A kind of simple fixed connection structure of railway tunnel protective door of the present invention, including protective doorframe, it is characterized in that：Institute
State detachable install on the side wall of protective doorframe and deflectable fan-shaped hinge is installed on rocker bar bearing, rocker bar bearing；The sector
Hinge, which has, is provided with least two dress holes separately in fanning strip and bearing pin, fanning strip plate face, perpendicular to fanning strip plate face
Bearing pin insertion rocker bar bearing circular hole in.
The beneficial effects of the invention are as follows the hole location on protective doorframe is fixed, and door opening position of opening then can be selected flexibly
Take, greatly avoid position of opening from conflicting with the position of embedded bar, improve perforate precision and quality on concrete door opening, fully
Ensure that bar planting or chemical drift bolt screw etc. fasten the fastening effect of mounting means；Simple in construction, part is easily assembled, dismounting and more
Change, effectively reduce site operation installation difficulty, and improve the fastening effect of protective door and concrete door opening, ensured protection
Door fire prevention, the capability of antidetonance give full play to.
Brief description of the drawings
This specification includes following three width accompanying drawing：
Fig. 1 is a kind of stereogram of simple fixed connection structure of railway tunnel protective door of the invention；
Fig. 2 is the stereogram of fan-shaped hinge in a kind of simple fixed connection structure of railway tunnel protective door of the invention.
Fig. 3 is the vertical of the pad of composition rocker bar bearing in a kind of simple fixed connection structure of railway tunnel protective door of the invention
Body figure.
Component and corresponding mark are shown in figure：Protective doorframe 10, fan-shaped hinge 20, fanning strip 21, mounting hole 22, pin
Axle 23, rocker bar bearing 30, pad 31, half slot 32, circular hole 33, bolt mounting holes 34.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Referring to Figures 1 and 2, a kind of simple fixed connection structure of railway tunnel protective door of the invention, including protective door door
Frame 10.Detachable install installs deflectable fan on rocker bar bearing 30, rocker bar bearing 30 on the side wall of the protective doorframe 10
Shape hinge 20.The fan-shaped hinge 20 has at least two mounting holes 22 separately, perpendicular to the bearing pin 23 of the plate face of fanning strip 21
In the circular hole 33 for inserting rocker bar bearing 30.
Reference picture 1, rocker bar bearing 30 has its axis and the perpendicular circular hole 33 of the plate face of fanning strip 21, is fanned by bearing pin 23
The deflectable certain angle of shape plate 21, makes door opening position of opening flexibly to choose, it is to avoid the position punching of position of opening and embedded bar
It is prominent, so as to improve perforate precision and the quality on concrete door opening, fully ensure that the fastening such as bar planting or chemical drift bolt screw is installed
The fastening effect of mode.
Reference picture 1 and Fig. 3, the rocker bar bearing 30 include two pads 31, are opened in the half slot 32 at the middle part of pad 31
Circular hole 33 is combined to form, the both sides of half slot 32 set bolt mounting holes 34.
Reference picture 1, it is unilateral in protective doorframe 10, rocker bar bearing 30 is formed using two pressings of pad 31, then pass through two
Rocker bar bearing 30 is fixedly mounted on protection doorframe 10 by group bolt fastener through the bolt mounting holes 34 on pad 31.Partially
The whole fanning strip 21 of modulation, avoids the position drilling of embedded bar in concrete door opening, will be fanned by bar planting or chemical drift bolt screw
Shape plate 21 is fixedly connected with concrete door opening.As can be seen here, concrete door can be adjusted flexibly by the rotation of sector hinge in the present invention
The hole location in hole, fully avoids embedded bar position, to obtain the hole that perforate is superior in quality, so as to coordinate bar planting or chemistry
The installation of crab-bolt screw rod, improves and coheres ability and anti-fatigue performance between protective door and concrete door opening.
Some of a kind of simple fixed connection structure of railway tunnel protective door of the invention described above that simply explains through diagrams
Principle, be not intended to by the present invention be confined to shown in and described concrete structure and the scope of application in, therefore it is every be possible to by
The corresponding modification utilized and equivalent, belong to apllied the scope of the claims of the invention.
