Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0016] During the assembly and construction of the steel pipe beam, it is necessary to weld the connecting plate on the steel pipe of the steel pipe beam. The connecting plate is an approximately rectangular steel plate with several round holes. The purpose of setting the round holes is to use nuts to connect the angle steel and the connecting plate together. The steel pipes are connected with angle steel to form a steel pipe beam.
[0017] When welding the connecting plate on the steel pipe of the steel pipe beam, the steel pipe beam assembly welding auxiliary support provided by the present invention can be used, and the support is used as an auxiliary tool for aligning the positions of the connecting plate and the steel pipe. Such as figure 1 or figure 2 As shown, the bracket includes two cross-arms of the same length and a reference plate connecte...

The invention discloses an auxiliary welding support for assembling a steel tube beam, and relates to the assembling field of the steel tube beam. The auxiliary welding support comprises two cross arms arranged on steel tubes of the steel tube beam, datum plates used for supporting connecting plates, adjusting rods and distance adjusting hold-down nuts. The adjusting rods are fixedly connected to the two ends of each datum plate, and the datum plates are connected beneath the cross arms through the adjusting rods and the distance adjusting hold-down nuts. The auxiliary welding support for assembling the steel tube beam is suitable for being used when the steel tube beam is assembled. By the adoption of the device, operation is made easy, the angles of the welded connecting plates are the same, the directions of the welded connecting plates are consistent, and therefore the assembling quality of the steel tube beam can be improved.
Description
technical field [0001] The invention relates to the field of steel pipe beam assembly, in particular to an auxiliary support for steel pipe beam assembly and welding. Background technique [0002] The cross section of the steel pipe beam is generally triangular or rectangular, most of which are triangular. The structural body of the triangular steel pipe beam is three steel pipes arranged in a triangle, and the steel pipes are connected by angle steel to form a beam. During the assembly process of the steel pipe girder, several pairs of connecting plates need to be welded on the steel pipe along the length direction of the steel pipe, and then the angle steels are connected with the connecting plates through distance-adjustable fixing nuts. The included angle between each pair of connecting plates on the steel pipe of the triangular steel pipe girder is 60°. In the process of assembling steel pipe beams, due to the large number of connecting plates welded on the steel pipe...
