Abstract
Bored tunnel arch grid installation tool belongs to auxiliary mould field during constructing metro tunnel.It is made of trishores bottom leg, supported rod erecting, screw nut assembly, Kato；Kato is located at top, is made of steel plate and reinforcing bar, two reinforcing bars is welded on the steel plate, for support grid steel frame；Screw rod is welded with below the steel plate of Kato, supported rod erecting is made of steel pipe, screw rod bottom end is inserted into supported rod erecting, it is screwed on the internal thread of supported rod erecting, and it is positioned by nut, trishores bottom leg is located at the bottom end of supported rod erecting, one supporting leg is welded as a whole with supported rod erecting, and another two supporting leg is movable supporting legs.Using the utility model arch grid installation tool, effectively solves artificial lift grid during construction personnel erects, relatively time-consuming problem of taking a lot of work in installation process avoids and vertical grid driven under exposed country rock there are security risks.Using bored tunnel arch grid installation tool, during grid erection, height is adjusted conveniently, grid arch connecting plate bolt hole carries out Dock With Precision Position, improves grid installation quality.
Description
Technical field
The utility model is related to one kind for arch grid installation tool in metro built by mining method engineering.
Background technology
Bored tunnel mining method construction is a kind of common construction method, the hard rock geology for the mechanized construction that has more than is needed in fortune
It is also needed using mining method construction with the subway station of large-sized section and air duct.Previous Mining Method bored tunnel top bar arch lattice
During grid installation, artificial lift often saves the grid of weight 200kg or so, relatively time-consuming, laborious, and often saves grid left and right sides
It in connecting plate docking operation, is difficult to adjust grid angle and height due to manually erecting grid, causes bolt connecting hole cannot essence
Quasi- docking, has the fissure of displacement, leads to not the situation of installation bolt nut.There are grid installation effectiveness is low, ropy shortcoming.
Invention content
In order to solve above-mentioned technical problem, the utility model provide it is simple in structure, it is convenient and practical, be used for tunneling
The auxiliary mould of tunnel arch grid.
The purpose of this utility model is achieved through the following technical solutions：Bored tunnel arch grid installation tool,
It is characterized in that, is made of trishores bottom leg, supported rod erecting, screw nut assembly, Kato；The Kato is located at top, by
Steel plate and reinforcing bar are made, and two reinforcing bars are welded on the steel plate, for support grid steel frame；Spiral shell is welded with below the steel plate of Kato
Bar, supported rod erecting are made of steel pipe, and screw rod bottom end is inserted into supported rod erecting, is screwed on the internal thread of supported rod erecting, and pass through spiral shell
Mother's positioning, trishores bottom leg are located at the bottom end of supported rod erecting, one supporting leg is welded as a whole with supported rod erecting, another two branch
Leg is movable supporting legs.
Preferably, it is supportted in nut outer equipped with hand.
Preferably, Kato is processed using 5mm steel plates, and width adds 1cm for width external outside grid main reinforcement, in Kato both sides
High 10cm, the reinforcing bar of a diameter of 22mm, for stationary grizzly are set.
Preferably, supported rod erecting uses 42 steel pipes of Ф, and screw rod uses length 600mm, the scaffold jacking of diameter 32mm；Spiral shell
Female hand support is using the hollow bolt body of rod of Ф 25, length 10cm, both sides arrangement.
The beneficial effects of the utility model：The utility model using the above structure, in use, the tooling is placed in operation tunnel
Road arch face lives arch grid by Kato support, and passes through nut hand support adjusting screw rod, realizes supported rod erecting and trishores bottom leg
Height be adjusted according to top bar actual height.Trishores bottom leg is by a fixed supporting leg and two movable supporting legs structures
Into can adapt to the levelling fixation in uneven place.In the installation of bored tunnel top bar grid, the utility model arch lattice are used
Grid installation tool, effectively solving during construction personnel erects needs to be lifted up, relatively time-consuming in installation process to take a lot of work
Problem is effectively saved the construction time, controls grid installation quality.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
Bored tunnel arch grid installation tool, by trishores bottom leg 1, supported rod erecting 2, screw nut assembly, Kato 5
It forms；Kato 5 is located at top, is processed using 5mm steel plates, and width is externally width adds 1cm outside grid main reinforcement, in 5 liang of Kato
Side sets high 10cm, the reinforcing bar of a diameter of 22mm, for stationary grizzly 6.Screw rod 4 is welded with below the steel plate of Kato 5, is supported
Upright bar 2 uses 42 steel pipes of Ф, the length 600mm of screw rod 4, diameter 32mm；4 bottom end of screw rod is inserted into supported rod erecting 2, vertical with supporting
The internal thread of bar 2 is screwed on, and is positioned by nut, and being equipped with hand in nut outer supports 3.Nut hand support 3 uses the middle spare anchor of Ф 25
Club shaft, length 10cm, both sides arrangement facilitate adjusting bracket height；Trishores bottom leg 1 is located at the bottom end of supported rod erecting 2,
One supporting leg is welded as a whole with supported rod erecting, and another two supporting leg is movable supporting legs.
