The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
With Fig. 2～Fig. 8 is that the present invention will be described for example.
As Fig. 2, shown in Figure 3, the frock that is used for the assembly welding I-beam comprises a base 4 and 12 positioning units 10.
12 positioning units 10 equidistantly are fixed on the base 4.The length of the length of base 4 and I-beam to be welded is complementary, and the width of width and I-beam to be welded is complementary.Particularly, the length of base 4 can be 16.6 meters (m).Base 4 can be formed by 4 die mould channel-section steels and 24 channel-section steel reinforcement assembly weldings.
As shown in Figure 4, positioning unit 10 comprises upper cover plate positioning baffle 6, lower cover positioning baffle 7, riser location gusset 8, movable bolt 9 and base plate 5.
Upper cover plate positioning baffle 6 is fixed on the one side on the base plate 5, lower cover positioning baffle 7 is fixed on the base plate 5 another side relative with upper cover plate positioning baffle 6, be the both sides that upper cover plate positioning baffle 6 and lower cover positioning baffle 7 symmetries are fixed on riser location gusset 8, realized to be benchmark right I-beam location in location with the riser.Like this, cover plate can be done reversible deformation in advance, has satisfied behind the I-beam assembly welding the requirement of lid flatness, has improved operating efficiency.
All be welded with the rectangle position block 91 that thickness is 20mm between riser location gusset 8 and upper cover plate positioning baffle 6, the lower cover positioning baffle 7, be used for guaranteeing that the distance between riser location gusset 8 and upper cover plate positioning baffle 6, the lower cover positioning baffle 7 can satisfy the placement demand of I-beam, in other words, concern by position block 91 restriction risers location gussets 8 and position between upper cover plate positioning baffle 6, the lower cover positioning baffle 7, be used for controlling two cover plates in frock with the relative position of riser, and guarantee the central lines of riser root face and two cover plates.Position block 91 also can be in the process of the frock in making present embodiment, be used for limiting the distance between riser location gusset 8 and upper cover plate positioning baffle 6, the lower cover positioning baffle 7, after riser location gusset 8, upper cover plate positioning baffle 6 and lower cover positioning baffle 7 are fixed, can remove position block 91.
Wherein, upper cover plate positioning baffle 6 as shown in Figure 5, comprise the left clamping plate 61, right clamping plate 62 and the location-plate 63 that are vertically fixed on the base plate 5, left side clamping plate 61 and right clamping plate 62 symmetries are fixed on the both sides of location-plate 63, left side clamping plate 61 are clipped in the middle location-plate 63 with right clamping plate 62, and location-plate 63 is played positioning action.The inner surface of location-plate 63 promptly plays positioning action with lower cover positioning baffle 7 facing surfaces to upper cover plate.
Lower cover positioning baffle 7 comprises two parallel splints being vertically fixed on the base plate 5 71, intermediate plate 72 and two side plates 73 as shown in Figure 6.
Two side plates 73 are separately positioned on the outside of two parallel splints 71, and intermediate plate 72 is between two parallel splints 71, and is vertical with two parallel splints 71.Two side plates 73 are fixed two parallel splints 71 jointly with intermediate plate 72.The side surface that two parallel splints 71 and upper cover plate positioning baffle 6 are relative plays positioning action to lower cover.Movable bolt 9 is located in the middle part of intermediate plate 72, and the top is positioned at the side that intermediate plate 72 deviates from upper cover plate positioning baffle 6, in order to regulate the position between lower cover, riser and the upper cover plate.
When using the above-mentioned frock that is used for the assembly welding I-beam, at first two risers 3 of not splicing are put into frock, guarantee that riser 3 and riser locate gusset 8 horizontal planes and overlap fully, the fixed interval (FI) is stayed at the splicing welding joint place.
The lower cover 2 that splicing is good is put into frock, under the situation that guarantees lower cover 2 flatnesses, twisting movable bolt 9, lower cover 2 is moved to riser 3, at this moment, riser 3 and lower cover 2 be the generating unit displacement component simultaneously, but does not influence the perpendicularity and the flatness of I-beam integral body, obtains relative position schematic diagram as shown in Figure 8.
Then, to I-beam " " tack welding is executed in the weld seam both sides to T, and spot welding length is not less than 50mm, and the spacing between the spot welding is 300mm, has enough intensity to guarantee I-beam when integral body hangs out frock, the deflection before reducing to weld.
Welding at last.Adopt the Type of Welding of symmetrical backstep welding during welding, guarantee the unanimity of the hot input quantity in weld seam both sides, reduce welding deformation amount.
Wherein, upper cover plate 1 and riser 3 are divided into two sections splicings, and lower cover 2 is divided into three sections splicings, and splicing welding joint is two " V " type weld seams of butt joint.Requirement is carried out postwelding smoothing operation to the upper cover plate 1 of splicing, guaranteeing flatness, the riser group to after splicing again.
The frock that is used for the assembly welding I-beam that the foregoing description provides can reach following technique effect by positioning unit and base: be the location benchmark with the riser, the positioning process about having simplified between cover plate and riser has increased the degree of accuracy of each several part location; Can do reversible deformation in advance to upper cover plate, solve the welding deformation problem to a great extent; Simplified the production process of I-beam, assembling speed is fast, has improved production efficiency.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
