Description
Technical field
The utility model belongs to tunnelling winning apparatus technical field, and in particular to one kind is used for steel bar joist supporting lane
The portable antidetonation measuring point device in road.
Background technique
During the construction line-putting of tunnelling, measurement staff hammers into timber wedge between top plate and joist, in wood
Small nail is followed closely on wedge, suspension cotton rope is used as measuring point device, when personnel operate, is needed to climb to using ladder to be swung on top plate with hammer and be hit
Timber wedge is squeezed into timber wedge in the gap of joist and top plate, often has carbon block, stone block to fall because tapping vibration in the process,
The personnel of following staircase personnel and surrounding work are pounded, the timber wedge measuring point device fixed is often subject to blow out during tunnelling
Vibration and loosen, fall off, cause measure work repeat.
Summary of the invention
In order to overcome the deficiencies of the prior art, the utility model provides a kind of portable antidetonation measuring point device, measuring point body product
It is small, shock resistance is good, not easily to fall off, stability is good, safety convenient, be widely used in the tunnel of steel bar joist supporting.
The purpose of this utility model is achieved through the following technical solutions:
A kind of portable antidetonation measuring point device, including the first iron block, the second iron block, screw rod, a side of first iron block
The first groove for being clamped steel bar joist is offered on face, is offered on a side end face of the second iron block for being clamped reinforcing bar support
Second groove of beam offers the first threaded hole in the middle part of first groove, and first threaded hole is extended through to first
In the middle part of another side end face of iron block, offer the second threaded hole in the middle part of the second groove, second threaded hole extend through to
In the middle part of another side end face of second iron block, first threaded hole and the second threaded hole are connected by screw rod, first iron block
And set that there are two nuts on the second screw rod between iron block.
Further, the edge of another side end face of first iron block and the second iron block is offered for fixing cotton rope
Through-hole.
Further, first iron block and the second iron block are cuboid-type column structure, and the first of the first iron block
Second groove of groove and the second iron block is away from each other setting.
Further, the equivalent width in the length of the screw rod and steel bar joist supporting between two joists.
The utility model has the beneficial effects that the first groove of the first iron block and the second groove of the second iron block are connected in respectively
On steel bar joist, with two, band nuts by screw rod and the first threaded hole and the second screw hole, nut is twisted, so that two
Iron block fastening is connected on joist, this portable antidetonation measuring point device installation is easy to operate, small in size, in use by explosion
Impact force is much smaller than timber wedge, and stability is good, is not easy to be destroyed, and safety is time saving, can be widely used for steel bar joist supporting
The measuring point in tunnel uses.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
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, it is clear that 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 making creative work
