Description
Technical field
The present invention relates to technical field of tunnel construction, in particular to connecting plate construction dress between the first branch steel arch-shelf in a kind of tunnel
It sets.
Background technique
In recent years, China's highway construction enters fast-developing period, and the investment in the inland province Duo Shan is increasing,
Mountainous region is again in the majority with tunnel, and preliminary bracing is even more quite important during constructing tunnel, and steel arch-shelf is even more main support, is
Guarantee the globality between steel arch-shelf, can all use junction steel plate, this construction method safe mass assurance coefficient is low, steel plate
Bore position is different, steel plate and I-steel welding position are different, and screw hole on not, twist not by screw when causing just to prop up vertical arch
On, influence the globality of arch.
Summary of the invention
The purpose of the present invention is to provide one kind can guarantee that I-steel and the unified tunnel in connecting plate welding position just prop up
Connecting plate constructing device between steel arch-shelf.
To achieve the above object, technical scheme is as follows:
A kind of first connecting plate constructing device between branch steel arch-shelf in tunnel, sets the connecting plate there are four through-hole including I-steel and surface,
The connecting plate is welded on the end of the I-steel, is bolted between the I-steel comprising triangular structure
Bracket, the cantilever tip is extended with support rod, and the support rod is equipped with connector, and the connector and telescopic rod connect
It connects, the telescopic rod other end is connected and fixed plate, and four guide rods are evenly distributed in the fixed plate, are set with connection on the guide rod
Plate.
The connector is hex nut.
The hex nut is welded on the support rod end.
The telescopic rod is threaded rod.
The fixed plate lateral surface welds two fixture nuts.
The threaded rod screws with the hex nut and fixture nut connect respectively.
The fixed plate is identical as the connecting plate size.
The end of the threaded rod is equipped with rotating handles.
The rotating handles are equipped with non-slip mat.
The protective pad is rubber pad.
Compared with prior art, triangular supports of the invention lie in I-steel side, are close to I-steel, can be radial
Be located by connecting plate；Connecting plate is identical as fixed plate size, it is ensured that welding position of the connecting plate on I-steel is opposite
It is unified；Threaded rod screws with hex nut and fixture nut connect respectively, can be to the radial position of connecting plate by rotating threaded rod
It sets and is finely adjusted, improve installation accuracy；The end of threaded rod is equipped with rotating handles, keeps the rotation of threaded rod more convenient.

Specific embodiment
Connecting plate constructing device between the first branch steel arch-shelf in tunnel shown in -7 referring to Fig.1, including I-steel 1 and surface are equipped with four
The connecting plate 2 of a through-hole 12, connecting plate 2 are welded on the end of I-steel 1, are connected between I-steel 1 by bolt 13, triangle
The bracket 3 of structure lies in the side of I-steel 1, bracket 3 is by two identical triangles of reinforcement fabrication, and by two three
Three angular angles correspond to reinforcing bar of burn-oning two-by-two, and extend a reinforcing bar on top, and stretching forms support rod 4,4 end of support rod
A hex nut 6 is welded, hex nut 6 is screwed with threaded rod 6 and connect, 10 outside of the other end and fixed plate of threaded rod 6
Two fixture nuts 9 screw connection, uniformly distributed four guide rods 11 on the inside of fixed plate 10, on four guide rods 11 and connecting plate 2
Through-hole 12 is corresponding, and connecting plate 2 is sleeved on four guide rods 11, and connecting plate 2 is identical as the size of fixed plate 10,
The end of threaded rod 6 is equipped with rotating handles 7, and rotating handles 7 are equipped with rubber pad 8.
In use, four light holes of connecting plate are covered triangular structure stent laid out flat in fixation in I-steel side
On four guide rods on plate, Primary Location can be completed to connecting plate in this way, then push bracket, connecting plate is made to be adjacent to I-shaped
Position of the I-steel end on connecting plate is observed in steel end, can be by rotating rotating handles, to even if necessary to adjust
The position of fishplate bar is finely adjusted, and is adjusted to suitable position, and connecting plate is welded on I-steel end, connecting plate can be completed
Welding.
The I-steel that connecting plate is welded is transported to scene, as long as by each unit I-steel end when Chu Zhili arch
Connecting plate screw alignment, screws on bolt.
