Technical field
The invention discloses a kind of tunnel grillage moulding bed and its processing method, specifically a kind of Tunnel institute
With grillage moulding bed and its processing method, belong to highway tunnel construction technical field.
Background technique
Traditional grillage processing flow are as follows:
Arch full-page proof → welding stirrup and other components → scene examination spelling → check are put in preparation of construction → debugging forming mill →
→ installation.
From above-mentioned grillage traditional processing process, it can be found that:
1) setting-out is repeated.Carry out arch processing every time and be required to relay arch full-page proof, and full-page proof cannot to reinforcing bar into
Row is effectively fixed；
2) of poor quality.In welding process, arch top bars are easy to shake, and the welding is not firm, and easy deviation, quality are not easy
Guarantee；
3) limited space.To place space requirement height during setting-out, it is easy to be limited by processing factory space；
4) inefficiency.For guarantee reinforcing rib quantity, there can only be a worker successively to weld reinforcing rib from left to right every time,
According to each reinforcing rib size, rough estimate reinforcing rib position；
5) at high cost, processing quality is not easy to guarantee.Easily cause main reinforcement deviation, stirrup position skew, reinforcing rib spacing inclined
Technical requirements are not met greatly and cause phenomenon of doing over again, and are generated the wasting phenomenon in artificial and financial resources, are unfavorable for cost control.
In conclusion traditional grillage processing due to repeating setting-out, causes, work efficiency is low, quality is difficult to ensure.

Shelf's design on arch bridge width, height, bar diameter process main reinforcement fixing steel plate 1；Suitable height and i-beam frame 2 are processed according to worker
Width produce moulding bed support frame 3；
2) surveying setting-out
With total station, setting-out goes out the temporary holding location of moulding bed support frame 3 on reinforcement yard ground, in i-beam frame 2
On according to 9 equal part of carry out of length, determine the fixation position of main reinforcement fixing steel plate 1；
3) moulding bed assembles
According to setting-out position, first in processing factory's ground fixing moulding bed structure support frame 3, then welded on moulding bed support frame 3
Fixed i-beam frame 2, finally according to the fixed main reinforcement fixing steel plate 1 of Along ent on i-beam frame 2, fixed point is fixed for each main reinforcement
Position 1 lower part of steel plate and 2 junction of i-beam frame, fixing means are spot welding consolidation；
4) moulding bed is checked
After being completed, fixation position of the main reinforcement fixing steel plate 1 on i-beam frame 2 is checked, after confirmation is qualified
To the spot welding position of main reinforcement fixing steel plate 1 and i-beam frame 2 again reinforcement of weld, the processing of moulding bed is completed.
The beneficial effects of the present invention are:
1) main reinforcement fixing steel plate 1 is processed according to the design size of grillage, 1 spacing of every two pieces of main reinforcement fixing steel plates is small,
It can quick and precisely be positioned according to the relative position of reinforcing rib and main reinforcement fixing steel plate 1 when welding；
2) four main reinforcements of grillage are fixed in main reinforcement locating slot 4, are not easy to shake, are improved welding quality；
3) reinforcing rib position is quickly positioned according to steel plate position, can be welded simultaneously with several workers, be improved the life of arch
Produce efficiency；
4) moulding bed interior in a limited space can be placed, and not have to repeat setting-out space, easy to operate；
5) by fixation of the moulding bed to reinforcing bar, accurate positioning, welding quality is good, reduces unqualified arch quantity, reduces
Waste, has saved cost.
