Abstract
The utility model relates to an arch rib spelling bed-jig with adjustable, including a plurality of crossbeams that set up side by side, two or more landing legs of every crossbeam bottom welding, many distribution roof beams of welding between each beam top surface, a reaction frame is established respectively at every crossbeam both ends, every reaction frame is towards crossbeam center one side welding bracket, the roof both sides of bracket weld respectively one with bracket roof vertically limiting plate, the bracket roof is improved level and is set up a jack, the base of jack supports at the montant towards crossbeam center one side, the piston rod front end of jack is towards the crossbeam center. The utility model discloses the flexible length adaptation of accessible adjustment both sides jack is linear of different arch ribs, can improve the efficiency of construction, practices thrift construction cost.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a processing of steel arch bridge's arch rib is related to, concretely relates to arch rib spelling bed-jig with adjustable.
Background
The ribs of steel arch bridges are usually machined in the back field segments, each rib segment being made up of several smaller segments which are assembled and welded on a jig. The existing jig frame comprises a pedestal, when arch rib segments are spliced, a plurality of segments are hung on the pedestal, the position of each segment is adjusted according to the line type of an arch rib, limiting rods are welded on two sides of the pedestal to position each segment, and then welding is carried out between each segment. Because the arch rib line type of different arch bridges is different, even the arch rib of the same arch bridge, the radian of different sections is different, therefore all sections need readjust and welding the gag lever post when splicing, the efficiency of construction is lower.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide an arch rib spelling bed-jig with adjustable, make the arch rib processing that a bed-jig can be used to multiple line type to improve the efficiency of construction.
The technical scheme of the utility model as follows:
the utility model provides an arch rib spelling bed-jig with adjustable, includes a plurality of crossbeams that set up side by side, two or a plurality of landing legs of every crossbeam bottom welding, many distributive girders of welding between each beam top surface, its characterized in that: two ends of each cross beam are respectively provided with a reaction frame, each reaction frame comprises a vertical rod, the lower end of the vertical rod is welded with the top surface of the cross beam, and an inclined support rod is welded between the upper end of the vertical rod and the end part of the cross beam; a bracket is welded on one side of the vertical rod of each reaction frame, which faces to the center of the cross beam, two sides of the top plate of each bracket are respectively welded with a limiting plate vertical to the top plate of each bracket, a jack is horizontally arranged on the top plate of each bracket, the base of each jack is supported on one side of the vertical rod, which faces to the center of the cross beam, and the front end of the piston rod of each jack faces to the center of the cross beam.
The utility model discloses an adjustment both sides jack's flexible length, the linear of adaptable different arch rib, the commonality is strong, and governing speed is fast, can improve the efficiency of construction, practices thrift construction cost.

fig. 2 is a side view of the present invention;
fig. 3 is a perspective view of the present invention in use.
Detailed Description
As shown in fig. 1, 2 and 3, the utility model comprises a plurality of parallel beams 1, two or more support legs 2 are welded at the bottom of each beam, a plurality of distribution beams 3 are welded between the top surfaces of the beams, a reaction frame is respectively arranged at both ends of each beam, each reaction frame comprises a vertical rod 4, the lower end of the vertical rod is welded with the top surface of the beam, and an inclined strut 5 is welded between the upper end of the vertical rod and the end part of the beam; a bracket 6 is welded on one side of a vertical rod 4 of each reaction frame towards the center of a cross beam, two limiting plates 7 are respectively welded on two sides of a top plate of each bracket, a jack 8 is horizontally arranged between the two limiting plates on the top plate of each bracket, a base of each jack 8 is supported on one side of the vertical rod 4 towards the center of the cross beam, and the front end of a piston rod of each jack faces the center of the cross beam. Two limiting plates on the bracket can prevent the jack from falling off from the bracket.
As shown in fig. 1 and 3, when the utility model is used, the arch rib block 9 to be assembled is hung on the distribution beam of the jig frame, and after each block is adjusted to the design position according to the design line type of the arch rib, the jacks 8 at two sides are started to jack each arch rib block tightly to position the arch rib block, and then the welding between each block is carried out; after welding of one arch rib segment is completed, the jack is retracted, the arch rib segment is lifted away from the jig frame, and the next segment is welded on the jig frame in the same way.
