Abstract
The utility model discloses a case-type steel main beam rectifying device used during construction. When the conventional steel main beams twist during actual production application, no existing equipment can be used for rectifying the steel main beams, so that the service life of a bridge is shortened, economic waste is caused and safety hazard is caused. The case-type steel main beam rectifying device used during the construction structurally comprises a steel cross beam (1) of which the two ends are connected with the steel main beam, and a steel oblique beam (3) which is connected with the steel main beam (2), wherein jacks (4) are arranged at the two ends of the lower part of the steel cross beam; the lower part of the steel cross beam is connected with a steel post (5); and the steel post is connected with the jack through a steel threaded wire (6). The case-type steel main beam rectifying device is used for bridge construction.
Description
Technical field:
The present invention relates to a kind of field of construction of road bridges, be specifically related to a kind of construction raising middle flask shaped steel girder apparatus for correcting.
Background technology:
When existing box steel girder produces when reversing in actual applications, there is not ready-made equipment to proofread and correct, to put the application life that makes bridge and reduce, economy causes waste, and safety causes a hidden trouble.
Summary of the invention:
The purpose of this invention is to provide a kind of extraordinary member of torsion phenomenon effect and job practices of correcting girder steel.
Above-mentioned purpose realizes by following technical scheme:
A kind of construction raising middle flask shaped steel girder apparatus for correcting, two ends connect the gooseneck of described steel girder, the steel cant beam that is connected with described steel girder, described jack is equipped with at two ends, described gooseneck bottom, described gooseneck bottom connects steel column, and described steel column connects described jack by the steel streakline.
Described construction raising middle flask shaped steel girder apparatus for correcting, construction raising middle flask shaped steel girder apparatus for correcting, described steel column diameter is greater than 530 millimeters.
Beneficial effect:
1. the present invention can correct the position deviation of girder steel and reverse, effective, economical and practical, install simple.
Reversing of the rectifiable high-altitude of the present invention heavy section steel girder steel oversimplified work progress, raises the efficiency.
The present invention has rational in infrastructure, safe and reliable advantage, and this product can repeat practicality, and is economical and practical.
The present invention applies counter-force by the large-tonnage hydraulic jack, and the precision of adjustment can be accurate in 1 millimeter, has guaranteed quality simultaneously.
The present invention adopts the combination of fritter steel plate to get final product this fastener of welding production, has reduced engineering cost.
The present invention is low from heavy and light, labour intensity, reaches energy saving purposes.
Description of drawings:
Accompanying drawing 1 is the structure chart of this product.
Accompanying drawing 2 is elevation of accompanying drawing 1.
Accompanying drawing 3 is plan views of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Construction raising middle flask shaped steel girder antidote, often produce girder transposition situation in the large-scale bridge grain construction, method of the present invention be at box steel girder when generation is reversed, employing applies counter-force under the steel girder of installation, counter-force acts on the lower edge of box steel girder by the shaped steel fastener, the opposite side of shaped steel fastener connects jack, when the jack pressurization applies counter-force, can produce the method for the trend reverse to box steel girder, to correct the position deviation of the reversing of girder steel, rectifiable girder steel.
Embodiment 2:
A kind of construction raising middle flask shaped steel girder apparatus for correcting, its composition comprises: two ends connect the gooseneck 1 of described steel girder, the steel cant beam 3 that is connected with described steel girder 2, described jack 4 is equipped with at two ends, described gooseneck bottom, described gooseneck bottom connects steel column 5, and described steel column connects described jack 4 by steel streakline 6.Described steel column diameter is greater than 530 millimeters.
When carrying out the installation of large bridge superposed beam sections, the installation of gooseneck is comparatively difficult, and main cause is that box steel girder has produced reversing to the inside under the effect of concrete slab, suspension cable pulling force, the deadweight of bridge floor loop wheel machine etc.Through multinomial public relations, we test employing and apply anti-top under the goosenecks of installation, the support reaction on anti-top acts on the lower edge outside of box steel girder by the shaped steel fastener, when the jack pressurization applies anti-top, box steel girder is produced the trend reverse laterally, in order to offset steel girder reversing to the inside.Finally finished the installation of bridge superposed beam sections, belonged to the world initiation.
