Abstract
The utility model discloses an assembled tunnel supporting rack, including arched girder and longeron, a plurality of arched girder parallel arrangement, and the arched girder radian is the same with the hole body radian that will support, a plurality of fixed longerons at the interval on the arched girder, longeron and arched girder mutually perpendicular, every net that forms at longeron and arched girder all is fixed with steel wire mesh sheet, every arched girder both ends all is fixed with altitude controller, altitude controller's structure does: nut upper portion sets up the screw rod, and the lower part sets up down the screw rod, and goes up screw rod and lower screw flight opposite direction, it is terminal to go up the fixed arched girder of screw rod, and the sole is fixed to lower screw rod. The utility model discloses a combination structural design, the swift installation of being convenient for, and arched girder height -adjustable easily realize reaching and initiatively preventing the effect tunnel top back pressure, the all standing is all carried out to steel wire mesh sheet gemel arch girder system, has realized that the tunnel total cross -section protects.
Description
Technical field
This utility model is related to railway traffic construction field, and in particular to a kind of assembling for railway tunnel internal protection
Formula tunnel support frame.
Background technology
At present, the protection for local concrete slump occurring to railway tunnel inside is only that wood is set up in the middle of steel column with some
Plate carries out emergency processing, or is having local at slump to carry out mesh sheet anchoring, and such pretective acreage is limited, poor reliability, it is impossible to real
Now tunnel internal carries out long-term total cross-section protection.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of assembled tunnel support frame, realizes arched girder and indulges
Beam quickly splicing and back-pressure is implemented at the top to tunnel, plays active preventive effect, and protective range width, quick for installation, safety can
Lean on.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of assembled tunnel support frame, including arched girder and longeron, some arched girders are arranged in parallel, and arched girder radian with
The hole body radian to be supported is identical, and fixed some longerons are spaced on the arched girder, and the longeron is mutually perpendicular to arched girder；
Each grid that longeron and arched girder are formed is fixed with steel fabric sheet；Each arched girder two ends is fixed with height adjuster.
Further, the structure of the height adjuster is：Nut top arranges upper screw rod, and bottom arranges lower screw rod, and
Upper screw rod is in opposite direction with lower screw flight；Upper screw rod fixes arched girder end, and lower screw rod fixes sole.
Further, the arched girder is multisection type, is connected by flange between per section.
Further, the connected mode between the longeron and arched girder is：Connecting plate is fixed with arched girder, longeron is connected to
On connecting plate.
Further, the longeron is bolted with connecting plate.
Compared with prior art, the beneficial effects of the utility model are：Combined structure design is employed, is easy to quick peace
Dress, and arched girder height adjustable, it is easy to accomplish to tunnel top back-pressure, so as to reach active preventive effect, steel fabric sheet is to arched girder
System carries out all standing, realizes tunnel total cross-section protection.

Specific embodiment
This utility model is described in further detail with reference to the accompanying drawings and detailed description.This utility model is carried
For a kind of assembled tunnel support frame, its structure is：Including arched girder 4 and longeron 5, some arched girders 4 are arranged in parallel, and encircle
The radian of beam 4 is identical with the hole body radian to be supported, and fixed some longerons 5, the longeron 5 and arch are spaced on the arched girder 4
Beam 4 is mutually perpendicular to；Each grid formed in longeron 5 and arched girder 4 is fixed with steel fabric sheet 3；Each two ends of arched girder 4 is solid
Surely there is height adjuster 1.
The structure of the height adjuster 1 is：The top of nut 8 arranges upper screw rod 7, and bottom arranges lower screw rod 9, and upper screw rod
7 is contrary with the hand of spiral of lower screw rod 9；Upper screw rod 7 fixes the end of arched girder 4, and lower screw rod 9 fixes sole.Employ upper and lower two
The device of the engagement composition of screw rod 7,9 of different rotation directions, is machined with upper and lower two kinds different rotation direction screw threads in nut 8, rotate nut 8
When, screw rod 7 and lower screw rod 9 synchronously rise or fall on two, realize hangar tunnel integral elevating, reach and implement back-pressure to tunnel top
Purpose.
Fig. 2 shows this utility model device assembled tunnel support frame, and this device is made up of multispan, often across for one
Unit, unit is consisted of：There is the arched girder 4 that multistage is spliced, per section docks by flange 2；In the two ends bottom of every arched girder 4
The height adjuster 1 of bidirectional screw is installed, for realizing back-pressure of the arched girder 4 to tunnel top, there are four per unit.Per root
Evenly spaced mesh sheet gripper shoe is welded with arched girder 4, the shackle hung when installing for steel fabric sheet 3 and on steel fabric sheet 3 connects
Connect；Many longerons 5 are evenly equipped between two arched girders 4, by means of two ends installing hole bolt the connecting plate 6 of arched girder 4 is anchored on
On.
After building and completing bow member device and tighten each node connecting bolt, then carry out soft protecting net i.e. steel fabric sheet
3 paving is hung, and the periphery of steel fabric sheet 3 is installed with steel wire rope, and the two ends of steel wire rope are tight with rope kayser.During paving steel fabric sheet 3, with interval
Uniform shackle passes through the steel wire rope of the surrounding of steel fabric sheet 3, and is connected with the gripper shoe being welded on arched girder 4, by steel fabric sheet 3
Reinforce on arched girder 4.
