In attached drawing be only that a part of the embodiment of the utility model is not paying wound for those of ordinary skill in the art
Under the premise of the property made is laborious, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the fixed device installation condition schematic diagram of the utility model embodiment cantilever.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Partition door is installed in subway main track section, stronger Piston Action Wind is generated when passing through because of train, is caused under partition door
Portion's jack safety device will appear loosening situation, leave security risk to train operation.
For this reason, it may be necessary to give subway main track interval partition door resetting safety device, the present embodiment provides a kind of English subways
The fixed device of the cantilever of partition door.Since partition door is in the open state usually, door leaf leans against at tunnel wall after opening, therefore
The fixed device of cantilever provided by the utility model, for being connected and fixed between partition door and tunnel wall.
Referring to Figure 1, specifically, the fixed device of cantilever includes the partition door base being fixedly installed on the door leaf of partition door 10
Seat 30, the tunnel surbase 40 that is fixedly installed in tunnel wall 20 and connection partition door pedestal 30 and tunnel surbase 40
Sissy bar 50.
Wherein partition door pedestal 30 is fixed on partition door 10 towards on the door leaf of tunnel wall 20, and fixed form can have more
Kind, it is the integrality for not destroying door leaf, uses and be welded and fixed herein.Lug 31 is provided on partition door pedestal 30, the lug
31 are connect in the form of hole axle with one end of sissy bar 50 by bolt 32.Although it should be noted that lug 31 and peace herein
One end connection of full pull rod 50, but its description is only connection structure, in the construction process, between lug 31 and sissy bar 50
Connection be final step, and after completing the connection of lug 31 and sissy bar 50, split pin 33 is plugged on bolt 32,
Prevent bolt 32 from falling off.
Tunnel surbase 40 includes the latch closure 43 of the substrate 41, support 42 and the semi-annular shape that are fixedly connected sequentially, wherein base
Plate 41 is fixed in tunnel wall 20.Here, between substrate 41 and tunnel wall 20, between support 42 and substrate 41 and latch closure
Between 43 and support 42, a variety of fixed forms are equally existed, welding manner can be used to weld tunnel surbase 40 integral,
It is welded in tunnel wall 20 again.
Because original load wall of tunnel wall 20 is completed, on the basis of not damaging former main structure, as preferred one
Kind of fixed form, the present embodiment using anchor bolt it is fixed by the way of fixation is realized to tunnel surbase 40, specifically, substrate 41 is in leaning on
The position of proximal edge is fixed in tunnel wall 20 by several base expanding and base expanding anchor bolts 44, which is pre- base expanding and base expanding anchor bolt 44, is
By dedicated reaming tool (reaming bit) the preparatory reaming in anchor hole bottom expanding anchor bolt, since pre- base expanding and base expanding anchor bolt 44 exists
After extension, with anchor hole inner sidewall there is no squeezing, the swelling stress at anchor hole is substantially zeroed, therefore pre-expansion hole anchor is very safe
Reliably；It is formed with the deep gouge for being equipped with nut 45 on support 42, offers through-hole in deep gouge bottom；It is equal at the both ends of latch closure 43
It is formed with screw thread, the both ends of latch closure 43 are penetrated in deep gouge by through-hole, and are fixed on support 42 by nut 45；Support 42 is logical
High-strength bolt 46 is crossed to be fixed on substrate 41.
In above-mentioned 40 work progress of tunnel surbase, construction procedure first consolidates substrate 41 as described in above-mentioned structural order
It is scheduled in tunnel wall 20, then latch closure 43 is fixed on support 42, finally complete the fixation between support 42 and substrate 41.Due to
The other end of sissy bar 50 is sheathed on latch closure 43, before latch closure 43 is fixed on support 42, first by the another of sissy bar 50
One end is sheathed on latch closure 43, then carries out the fixation between latch closure 43 and support 42.
Tunnel surbase 40 complete installation after, the center of circle of latch closure 43 in horizontal direction, and the lug 31 of partition door pedestal 30,
Sissy bar 50 and latch closure 43 are located at same axis.Sissy bar 50 is mounted on the lug 31 of partition door pedestal 30 by pin shaft
On, sissy bar 50 links up with adjustable-tightness, and sissy bar 50 is made to be constantly in tightening state, that is, completes the fixed dress of entire cantilever
The installation procedure set.
In order to further increase the stable connection between partition door 10 and tunnel wall 20, cantilever provided in this embodiment is solid
Determine device and is distributed between partition door 10 and tunnel wall 20 along the vertical direction including two with two or more.
Based on the fixed device of above-mentioned cantilever, on the other hand construction method that the utility model embodiment also provides, including with
Lower step:
After S100, installation partition door, partition door pedestal is welded in the design position of the fixed device of partition door door leaf upper cantilever；
S200, the position corresponding with partition door pedestal in tunnel wall, pass through base expanding and base expanding anchor bolt fixed substrate；
S300, after one end of sissy bar is set on latch closure, the both ends of latch closure are passed through into support, and will by nut
Latch closure is fixed on the support；
S400, support is fixed on substrate by high-strength bolt；
S500, the other end of sissy bar is placed on the lug of partition door pedestal, by the insertion of bolt be connected to every
On disconnected door pedestal, the installation of the fixed device of cantilever is completed.
In conclusion the fixed device of cantilever provided in this embodiment and its construction method, easy to install, operation is reliable, performance
Stablize；The security risk for eliminating the operation of subway special train, obtains good effect；Anchorage technology is extended using bottom, is mixed
Carry out reinforcing the best anchorage style for the use that supplies a gap in Xtah Crude Clay structure.
Embodiments described above does not constitute the restriction to the technical solution protection scope.It is any in above-mentioned implementation
Made modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution within the spirit and principle of mode
Within enclosing.
