Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 5, the welding conduction device of the utility model steel construction dock welding, for groove 101 end of welded two welded parts 10 of a kind of dock for being arranged on building or Inaedificatio steel skeleton structure body, carry out weld job in order to guide at groove 101.
As shown in Figures 1 and 2, the utility model welding conduction device preferred embodiment, it comprises: one leads welding block 1, lead rectangular blocks or other shapes that welding block 1 forms for acid bronze alloy, have for the abutment face 11 of closing at two welded parts 10 in the one side leading welding block 1, and be arranged at the one first concave arc curved surface 12 that abutment face 11 also corresponds to groove 101 end shape.Abutment face 11 is plane, make abutment face 11 can closely closing on two welded parts 10; And the area of the first concave arc curved surface 12 is greater than the area of groove 101 end, the curvature of its curved surface can change according to actual demand, and first the edge shape of concave arc curved surface 12 can be formed as corresponding to trapezoidal, triangle, U-shaped or other geometries of groove 101, depending on the shape of groove 101, therefore make the first concave arc curved surface 12 can cover the end of groove 101 completely, and then formation one weld space for having implemented leading of weldering.In addition, one end that the utility model leads welding block 1 can be provided with the fixed part 13 for being arranged on welded part 10 or backer board 20 (as shown in Figure 5), fixed part 13 specific embodiment is the groove 131 for being set on backer board 20, fixed part 13 can also be provided with the screw 132 that is communicated to groove 131, and one is locked together in fixation kit 133 in screw 132, fixation kit 133 preferred embodiment is general bolt or turns bolt soon, by forming the welding conduction device of the utility model steel construction dock welding like this.
Again as shown in Figures 3 and 4, in order to reach the object that recycling is led welding block 1 or is suitable for different groove 101 shape, the utility model is led the relative two sides of welding block 1 and is formed with an abutment face 11 respectively, and the first concave arc curved surface 12 that each abutment face 11 is provided with on above-mentioned the first concave arc curved surface 12, two abutment faces 11 can be identical shape or difformity.And the two ends of leading welding block 1 are respectively equipped with the fixed part 13 for being arranged on welded part 10 or backer board 20, the structure of fixed part 13 is same as described above.
As shown in Figures 5 and 6, when the utility model is used in the dock Welding Structure of steel skeleton structure body, can be set on a backer board 20 by the groove 131 of the fixed part 13 of leading welding block 1, the plate that root face is closed by groove 101 back side that backer board 20 is arranged on two welded parts 10, therefore make to lead groove 101 two ends that welding block 1 is arranged on welded part 10, make the first concave arc curved surface 12 of leading welding block 1 be covered in groove 101 end, by the closed at both ends of groove 101 and formed one lead weldering space.Meanwhile, the utility model can utilize the mode of the assembly 133 of being locked (general bolt or turn bolt soon), makes fixation kit 133 end be resisted against backer board 20, loosens depart to prevent from leading welding block 1 in weld job.
By like this, as shown in Figures 7 and 8, when carrying out weld job, opened by the first concave arc curved surface 12 of leading welding block 1 and made weldering, set out optimal electric current, voltage and weldering speed in this adjustment, then successively weld at groove 101, so can obtain preferably wlding 30 surface at groove 101 two ends, and do not need to carry out again to cut, grinding etc. repairs processing, reach and promote welding quality and simplify the effects such as welding sequence.In addition, the utility model is led welding block 1 and is adopted acid bronze alloy material to form, copper and steel can not weld together substantially, and the heat resistance of acid bronze alloy material is higher than steel, as long as after therefore completing welding, just can unclamp fixation kit 133 (general bolt or turn bolt soon) and welding block 1 will be led pull down, leave the structure of wlding 30 excellent surface quality, and can reuse pulled down lead welding block 1, reach and economize on resources and the benefit of environmental protection.
In addition, owing to being finally formed in wlding 30 surface contiguous at groove 101 two ends in the position of welded part 10, the angle that stress is concentrated may be there is, split from angle when earthquake may be caused to occur, for this reason, the utility model more can the first concave arc curved surface 12 be connected to abutment face 11 while formed one second concave arc curved surface, and the contrary another side that the first concave arc curved surface 12 is connected to abutment face 11 forms one the 3rd concave arc curved surface, by such structural design, make first, the section of second and third concave arc curved surface forms similar W character form structure, therefore when be used for leading be soldered into time, the structure of second and third concave arc curved surface can be utilized, the both sides of wlding 30 corner is originally caused to be formed with filling part respectively, stress in order to eliminate corner concentrates existing picture, the situations such as prevention wlding 30 splits, and welded firm effect can be promoted.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
