Summary of the invention
The utility model will overcome existing steel pipe truss welding above shortcomings, and a kind of steel pipe truss location, the special-purpose truss Main Girder Welding anchor clamps of assembling are provided.
The technical solution of the utility model is:
A kind of truss Main Girder Welding anchor clamps, it is characterized in that: comprise base plate, described base plate is connected to the upright support of some contour clamping plate along its horizontal axis equal intervals vertical welding, the top of the upright support of described clamping plate is welded with high-order clamping plate, described base plate also is welded with the low level clamping plate of symmetrical distribution in one line in the both sides of its horizontal axis, the center of described high-order clamping plate and described low level clamping plate is equipped with the metalworking arc surface of spill; Spacing between the girder steel pipe of spacing between the low level clamping plate arc surface axis of symmetry bottom the truss girder of design equates that the spacing between described low level clamping plate and the high-order clamping plate arc surface axis equates with the height of the truss girder of design.
Further, the outer periphery of the upright support of described clamping plate is useful on the clamping plate diagonal brace of strengthening described high-order clamping plate rigidity, and an end of described clamping plate diagonal brace is welded in the upright support of described clamping plate, and the other end is welded on the described base plate.
Further, described high-order clamping plate and described low level clamping plate are metalworking parts.
Further, described clamping plate diagonal brace is a channel member.
Preferably, described high-order clamping plate and described low level clamping plate and described base plate are the 20mm steel plate.
During use, the truss girder is made up jointly by girder steel pipe and steel pipe diagonal brace, and the steel pipe diagonal brace is connected each girder steel pipe.The metalworking arc surface of high-order clamping plate and low level clamping plate is shelved the girder steel pipe of different-diameter specification respectively, and the clamping plate diagonal brace is used for strengthening the rigidity of the high-order clamping plate in centre of weld jig.Dimensional requirement according to the truss girder, on the base plate axis, become a file to place with a determining deviation several weld jigs, between the low level clamping plate between the axis horizontal spacing of arc surface and high-order clamping plate and the low level clamping plate axis spacing of arc surface just satisfy the required distance each other of each girder steel pipe of truss girder.The fit-up gap is adjusted in the assembling of truss girder, location, all finishes on truss Main Girder Welding anchor clamps.When a plurality of truss Main Girder Welding anchor clamps join together, just can produce the truss girder in batches.
The beneficial effects of the utility model: use shaped steel spare and metalworking part to position, be assembled into truss Main Girder Welding anchor clamps dexterously, the accuracy of improved steel pipe truss girder location, assembling is applicable to the welding of the steel pipe truss girder of planar rectangular steel pipe truss welding processing.Simple in structure, easy to use, reduced labor strength, promoted truss assembly quality and labor productivity.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to Fig. 1-Fig. 2, a kind of truss Main Girder Welding anchor clamps described in the utility model, it is characterized in that: comprise base plate 1, described base plate 1 is connected to the upright support 4 of some contour clamping plate along its horizontal axis equal intervals vertical welding, the top of the upright support 4 of described clamping plate is welded with high-order clamping plate 5, described base plate 1 also is welded with the low level clamping plate 2 of symmetrical distribution in one line in the both sides of its horizontal axis, the center of described high-order clamping plate 5 and described low level clamping plate 2 is equipped with the metalworking arc surface 51 and the arc surface 21 of spill; Spacing between the girder steel pipe 6 of spacing between the low level clamping plate arc surface axis of symmetry bottom the truss girder of design equates that the spacing between described low level clamping plate 2 and the high-order clamping plate 5 arc surface axis equates with the height of the truss girder of design.
The outer periphery of the upright support 4 of described clamping plate is useful on the clamping plate diagonal brace 3 of strengthening described high-order clamping plate 5 rigidity, and an end of described clamping plate diagonal brace 3 is welded in the upright support 4 of described clamping plate, and the other end is welded on the described base plate 1.
