Abstract
The present invention relates to a kind of dividing plate cutting technique, it is characterised in that the described method comprises the following steps：（1）The Access Opening of cutting cutting for the first time, cable aperture；（2）Dust and mark datum line, sash rib and vertical ribbed stiffener installation site line in length and breadth；（3）Directrix in length and breadth is checked before the weldering of ribbed stiffener group, and stamps sample punching；According to datum line in length and breadth, tabula Board position is accurately positioned, after the registration of position, starts to cut notch.This invention removes the operation of amendment diaphragm plate notch during total spelling, diaphragm plate notch is respectively provided with high precision, installs accurate, and economic benefit is very notable.
Description
Technical field
The present invention relates to a kind of steel box-girder Slab element manufacturing process, more particularly to a kind of steel box-girder diaphragm plate secondary cut
Process, belongs to steel construction manufacture field.
Background technology
Traditional steel box-girder Slab element is made after using part panel elder generation cutting stock, then organizes the structures such as weldering ribbed stiffener.
This technique is widely used in roof and floor unit, web unit.When steel box-girder is always spelled, diaphragm plate notch
Therefore requirement very high is proposed to notch with roof and floor U rib accurately mates.As the notch of panel first is cut out into group again
Weldering ribbed stiffener, due to the deformation that welding, correction can be caused, causes during total spelling, and notch can not smoothly be matched with U ribs.
This process can cause always to spell the cutting amendment of process notch, cause always to spell low construction efficiency, waste big, the total constitution of steel box-girder
Amount is difficult to ensure that.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of easily operated dividing plate cutting technique, it is ensured that tabula
Plate assembly precision, improves total spelling production efficiency and the steel box-girder accuracy of manufacture.
The object of the present invention is achieved like this：1st, a kind of dividing plate cutting technique, the described method comprises the following steps：
Step one, one block of steel plate is taken, cut Access Opening, cable aperture on steel plate, then mark in length and breadth that datum line, level add with dusting
The installation site line of strength rib and vertical ribbed stiffener,；
Step 2, by it is above-mentioned once cut after steel plate be transferred to special diaphragm plate and cut moulding bed, first with cable on moulding bed
Hole and manhole are reference, mark datum line in length and breadth；It is again with reference to accurate with the datum line in length and breadth marked by dusting in step one
Datum line in length and breadth is depicted, the assembling of sash rib and vertical ribbed stiffener is then carried out；
Step 3, before the weldering of ribbed stiffener group to check directrix in length and breadth, and stamp sample punching, then carry out sash rib and vertical
The welding of ribbed stiffener, once welding, correction apply for checking and examination it is qualified after, then be transferred to numerical control plasma cutting machine and carry out cutting for notch and periphery
Cut.
Compared with prior art, the beneficial effects of the invention are as follows：This invention removes amendment diaphragm plate notch during total spelling
Operation, diaphragm plate notch is respectively provided with high precision, installs accurate, and economic benefit is very notable.
Specific embodiment
The present invention relates to a kind of dividing plate cutting technique, the described method comprises the following steps：
Step one, one block of steel plate is taken, cut Access Opening, cable aperture on steel plate, then mark in length and breadth that datum line, level add with dusting
The installation site line of strength rib and vertical ribbed stiffener, the line marked using dusting is the reference as follow-up accurate score line, in the past
Without the situation using powder marking, easily occur deviation during operative, influence dividing precision；
Step 2, by it is above-mentioned once cut after steel plate be transferred to special diaphragm plate and cut moulding bed, carry out the installation of ribbed stiffener, it is first
First, with cable aperture and manhole as reference on moulding bed, datum line in length and breadth is marked；It is vertical with what is marked by dusting in step one again
Horizontal datum line is with reference to accurately depicting datum line in length and breadth, then carry out the assembling of sash rib and vertical ribbed stiffener, once
The position line that dusts in cutting only makees installation site reference；Step 3, ribbed stiffener group weldering before to check directrix in length and breadth, that is, survey
Amount in length and breadth datum line to outline distance, and stamp sample rush, then carry out the welding of sash rib and vertical ribbed stiffener, one
Denier welding, correction apply for checking and examination it is qualified after, then be transferred to numerical control
CUT carries out the cutting on notch and periphery（That is secondary cut）, cutting pipette tips sky is walked, to be accurately positioned tabula
Board position, after the registration of position, starts to cut notch.
Claims (1)
1. a kind of dividing plate cutting technique, it is characterised in that the described method comprises the following steps：Step one, one block of steel plate is taken, in steel
Access Opening, cable aperture, then the installation site that datum line, sash rib and vertical ribbed stiffener in length and breadth are marked with dusting are cut on plate
Line；Step 2, by it is above-mentioned once cut after steel plate be transferred to special diaphragm plate and cut moulding bed, first with cable aperture on moulding bed
It is reference with manhole, marks datum line in length and breadth；It is again with reference to accurate quarter with the datum line in length and breadth marked by dusting in step one
Datum line in length and breadth is marked, the assembling of sash rib and vertical ribbed stiffener is then carried out；Step 3, ribbed stiffener group weldering before want
Directrix in length and breadth is checked, and stamps sample punching, then carry out the welding of sash rib and vertical ribbed stiffener, once welding, correction report
Test it is qualified after, then be transferred to numerical control plasma cutting machine and carry out the cutting on notch and periphery.
