Abstract

The utility model relates to tunnel construction equipment, in particular to an auxiliary tool for installing a steel arch center, which solves the problems of large labor intensity, low efficiency and lower safety coefficient when the steel arch center is manually installed. The auxiliary tool for installing the steel arch center comprises a channel steel type bayonet with an upper opened end, a screw rod is fixed at the lower end of the bayonet, a sleeve is sheathed outside the screw rod, a nut screwed on the screw rod is supported on the sleeve, and a wrench is fixed on the side wall of the nut. The auxiliary tool is simple to manufacture and less in material consumption, and the steel arch center can be elevated to a designed height by supporting of the screw rod through rotating the wrench welded on the nut, therefore, the labor intensity of workers can be greatly lightened, the procedure and operation time can be shortened, and the safety and reliability can be achieved.

Description

Steel bow member mounting auxiliary
Technical field
The utility model relates to constructing tunnel equipment, is specially a kind of steel bow member mounting auxiliary.
Background technology
Along with improving constantly of China's tunnel construction technology, large cross-section tunnel is more and more.Steel bow member junction is adopted welding steel and is connected by high-strength bolt, there are a lot of artificial origins during construction, cause the junction to have too many defective, therefore the junction just becomes the stressed weak spot of domain steel bow member, in order not weaken the ability of preliminary bracing carrying, steel bow member unit merogenesis is few more good more, so just cause some large cross-section tunnels (as Line for Passenger Transportation, when three track highways etc.) constructing, single-unit steel bow member is longer, heavier, mainly adopt when at present installing the steel bow member in the constructing tunnel workman pickaback hand lift, labour intensity is big, inefficiency and dangerous again.
Summary of the invention
There is the problem that labour intensity is big, efficient is low and safety coefficient is lower in the utility model when manually installing the steel bow member in order to solve, and a kind of steel bow member mounting auxiliary is provided.
The utility model is to adopt following technical scheme to realize: steel bow member mounting auxiliary, comprise the channel-section steel shape bayonet socket of upper end open, the bayonet socket lower end is fixed with screw rod, and screw jacket has sleeve pipe, the sleeve pipe upper support has the nut that is screwed on the screw rod, and the nut sidewall is fixed with spanner.When installing the steel bow member, steel bow member unit is lifted certain altitude, bayonet socket is blocked steel bow member unit, sleeve is supported on ground, by the rotating spanner nut screw rod is risen steel bow member jack-up, be welded to connect, overcome and have the problem that labour intensity is big, efficient is low and safety coefficient is lower when manually installing the steel bow member.
That the utility model is made is simple, consumptive material is few, is welded on spanner on the nut by rotation, makes screw rod support the steel bow member and is elevated to design height, has alleviated working strength of workers in a large number, has shortened operation and activity duration, and safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-bayonet socket, 2-screw rod, 3-sleeve pipe, 4-nut, 5-spanner.
The specific embodiment
Steel bow member mounting auxiliary comprises the channel-section steel shape bayonet socket 1 of upper end open, and bayonet socket 1 lower end is fixed with screw rod 2, and screw rod 2 is outer to be with sleeve pipe 3, and sleeve pipe 3 upper supports have the nut 4 that is screwed on the screw rod 2, and nut 4 sidewalls are fixed with spanner 5.In the specific implementation process, bayonet socket 1 A/F is slightly larger than steel bow member width, and screw rod 2 thicknesses guarantee that this device rigidity and steel bow member weight are complementary, and welds spanner on the nut that is complementary with screw rod, nut is installed in rear lower is provided with sleeve pipe on the screw rod, casing diameter is identical with nut.This device length is adjusted flexibly according to the scene.

Claims (1)

1. steel bow member mounting auxiliary, it is characterized in that: the channel-section steel shape bayonet socket (1) that comprises upper end open, bayonet socket (1) lower end is fixed with screw rod (2), the outer sleeve pipe (3) that is with of screw rod (2), sleeve pipe (3) upper support has the nut (4) that is screwed on the screw rod (2), and nut (4) sidewall is fixed with spanner (5).
