Abstract
The invention discloses an assembled type tunnel supporting and protecting shed frame which comprises arched girders and longitudinal beams, wherein the multiple arched girders are arranged in parallel; the radians of the arched girders are equal to that of a tunnel body to be supported; the multiple longitudinal beams are fixed on the arched girders at intervals; the longitudinal beams and the arched girders are perpendicular to each other; a steel wire meshes are fixed in each grid formed by the longitudinal beams and the arched girders; height adjusters are fixed at two ends of each arched girder; the structure of each height adjuster is as follows: an upper screw rod is arranged at the upper part of a nut, and a lower screw rod is arranged at the lower part of the nut; the thread directions of the upper screw rod and the lower screw rod are opposite; the tail end of each corresponding arched girder is fixed on the upper screw rod, and a foot plate is fixed on the lower screw rod. By the adoption of the design of a combined structure, the assembled type tunnel supporting and protecting shed frame is convenient and quick to mount; furthermore, the heights of the arched girders can be adjusted, so that back pressure on the top of the tunnel is easy to realize, and the active prevention effect can be achieved; the steel wire meshes can fully cover the arched girder system, so that protection of the whole section of the tunnel is realized.
Description
Technical field
The present invention relates to railway traffic construction field, be specifically related to a kind of assembled tunnel for railway tunnel internal protection
Road supporting frame.
Background technology
At present, protection railway tunnel inside occurring local concrete slump is only to set up wood 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
Tunnel internal carries out long-term total cross-section protection now.
Summary of the invention
The technical problem to be solved is to provide a kind of assembled tunnel support frame, it is achieved arched girder and longeron are fast
Speed Pinyin connects and the top in tunnel is implemented back-pressure, plays actively preventive effect, protective range width, quick for installation, safe and reliable.
For solving above-mentioned technical problem, the technical solution used in the present invention 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
Hole body radian to be supported is identical, and fixing some the longerons in interval on described arched girder, described 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 are fixed with height adjuster.
Further, the structure of described height adjuster is: nut top arranges 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, described arched girder is multisection type, passes through Flange joint between every section.
Further, the connected mode between described longeron and arched girder is: be fixed with connecting plate on arched girder, and longeron is connected to
On connecting plate.
Further, described longeron is bolted with connecting plate.
Compared with prior art, the invention has the beneficial effects as follows: have employed combined structure design, it is simple to fast install, and
Arched girder height adjustable, it is easy to accomplish to tunnel top back-pressure, thus reach actively preventive effect, steel fabric sheet is real to arch-beam Structure
Row all standing, it is achieved that tunnel total cross-section protects.

Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.The one that the present invention provides
Assembled tunnel support frame, its structure is: include that arched girder 4 and longeron 5, some arched girders 4 are arranged in parallel, and arched girder 4 radian
Identical with hole body radian to be supported, fixing some the longerons 5 in interval on described arched girder 4, described longeron 5 is mutual with arched girder 4
Vertically；The each grid formed at longeron 5 and arched girder 4 is fixed with steel fabric sheet 3；Each arched girder 4 two ends are fixed with height
Degree actuator 1.
The structure of described height adjuster 1 is: nut 8 top arranges 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 arched girder 4 end, and lower screw rod 9 fixes sole.Have employed upper and lower two
The device of screw rod 7, the 9 engagement composition of different rotation directions, is machined with upper and lower two kinds of different rotation direction screw threads, rotates nut 8 in nut 8
Time, on two, screw rod 7 and lower screw rod 9 synchronize to rise or fall, it is achieved hangar tunnel integral elevating, reach tunnel top is implemented back-pressure
Purpose.
Fig. 2 shows apparatus of the present invention assembled tunnel support frame, and this device is made up of multispan, often across for a list
Unit, unit consists of: having the arched girder 4 that multistage is spliced, every section all docks by flange 2；Pacify in the bottom, two ends of every arched girder 4
Equipped with the height adjuster 1 of bidirectional screw, for realizing the arched girder 4 back-pressure to tunnel top, every unit has four.At every arch
All being welded with evenly spaced mesh sheet gripper shoe on beam 4, the shackle hung when steel fabric sheet 3 is installed and on steel fabric sheet 3 connects；
Between two arched girders 4, it is evenly equipped with many longerons 5, is anchored on the connecting plate 6 of arched girder 4 by means of two ends installing hole bolt.
After having built bow member device and having been tightened by each node connecting bolt, then carry out soft protecting net i.e. steel fabric sheet
The paving of 3 is hung, and steel fabric sheet 3 periphery is installed with steel wire rope, and the two ends wire clips of steel wire rope is locked.During paving steel fabric sheet 3, with interval
Uniform shackle is through the steel wire rope of steel fabric sheet 3 surrounding, and is connected with the gripper shoe being welded on arched girder 4, by steel fabric sheet 3
Reinforce on arched girder 4.
