The ditch 6, the rod of the power cylinder 9 lowers the traverse 10. The rollers fixed on the clamping levers 14 move along the traverse 10, the levers 14 of the side plate, to the folding stops 6 and to the wall of the beam. After tacking, the cylinder rod 9 raises the yoke 10. The levers 14 are moved to the center by the action of the springs, and the gantry 7 moves to the next technology

The invention relates to construction engineering, in particular to ancillary equipment for assembly and welding works, and can be used, for example, for assembling for welding box-section beams consisting of a wall, two sidewalls and elements of internal saturation.

The aim of the invention is the expansion of technological capabilities by providing an assembly for welding of variable cross-section beams.

Fig. 1 shows a device for assembling for welding box beams of that cross section, general view; in FIG. 2, the same plan view; figure 3 is a section aa in figure 1; figure 4 - node I in fig.Z; figure 5 is a section BC in figure 4; figure 6 - section bb In figure 4.

The device for assembly for welding of box-shaped beams consisting of wall 1, two sidewalls 2 and internal saturation elements - diaphragms 3, comprises a base 4 with a supporting surface 5 for wall 1 and folding stops 6 arranged in pairs along the entire length of the base 4,

The device is equipped with a portal 7 mounted on the south 8 and 8 directions along the base 4. On the portal 7, the power cylinder 9 is vertically fixed, on the rod of which the link of the traverse 10j is made in the form of a box-section beam. On the portal 7, the screw 11 is also fixed with the right and left ezboy, with two nuts 12 screwed on it. The screw 11 is equipped with a handle 13, On the nuts. 12 are pivotally suspended two clamping levers 14 of curved shape, fitted with a spring 15. On levers 14

chesky position. When assembling beams of various widths, turning the screw 11 with the handle 13, pushing or sliding the nuts 12 with the clamping levers 14 suspended on them. The design of the device is simple and reliable in operation and ensures the assembly of the beams of various sections by adjusting the distance between the clamping levers. 1 hp A-ly, 6 Il.

rollers 16 are installed with the possibility of interaction with the crosspiece 10. Each lever 14 comprises a protrusion 17 for pressing the sidewall 2 to the folding stop 6 and a roller 18 for pressing the sidewall 2 against the wall 1,

The device works as follows

In the initial position folding

stops 6 are raised up and locked. Portal -7 is in the extreme position, the rod of the power cylinder 9 is retracted, and the yoke 10 is raised up, Wall 1 with a pre-welded stiffener is placed on the supporting surface 5 of the base 4, side panels 2 are placed along the folding stops 6, They are given a command to operate a power cylinder 9, the rod of which lowers the yoke 10. The rollers 16 move along the traverse 10 and the clamping levers 14 are pressed by the protrusion 17 to the inner surface of the sidewalls 2 and the roller 18 presses the sidewall shelf 2 to the wall 1, and tacking is performed elements of the assembled beam on this site.

After tacking, a command is given.

to actuate the ram 9, the rod of which raises the yoke 10, the levers 14 are shifted toward the center by the action of the springs 15. Portal 7 moves to the next technology POSITION where the same OPA is repeated and

hanging on them clamping levers 14 to the desired size.

The proposed device, in comparison with the prototype, makes it possible to assemble beams with sidewalls that have curvature and torsion, with% of this, the sidewalls are edited by ensuring their reliable clamping. In addition, the device is simpler in design and more reliable in operation.
