Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Steel bridge deck kludge as shown in Figure 1 comprises the workpiece fixed station 2 that is provided with panel support face 21, is arranged on zigzag crossbeam 3, moving beam 4, expansion regulating mechanism that panel fixing structural, array on the workpiece fixed station 2 has U type rib holddown groove 31; Said zigzag crossbeam 3 is installed on the moving beam 4 through expansion regulating mechanism; Said moving beam 4 is positioned at panel support face 21 tops, said zigzag crossbeam 3 between panel support face 21 and moving beam 4 and U type rib holddown groove 31 openings of zigzag crossbeam 3 towards panel support face 21; Said zigzag crossbeam 3 with moving beam 4 do to be parallel to panel support face 21 translation, move along panel support face 21 normal direction with expansion regulating mechanism, U type rib holddown groove 31 is that groove and axially parallel are in the translation direction of zigzag crossbeam 3.
Steel bridge deck commonly used is a rectangle; Its U type rib 1b all along panel 1a width extend, along panel 1a length direction array; Therefore; In instance as shown in the figure, the length and width of panel support face 21 are the length and width of corresponding panel 1a respectively, moving beam 4, zigzag crossbeam 3 axially all along the length direction of panel support face 21, translation direction along panel support face 21 widths.Above-mentioned U type rib holddown groove 31 can adopt the V-type groove; But for fear of depressing back U type rib 1b distortion; In instance as shown in the figure, adopt the degree of depth less than U type rib 1b height, the cross section U type groove consistent with U type rib 1b; U type rib holddown groove 31 is axially along panel support face 21 widths, and it is axial also to be that U type rib holddown groove 31 is axially perpendicular to zigzag crossbeam 3.
During assembling, at first panel 1a is positioned on the panel support face 21 of workpiece fixed station 2, counter plate 1a positions and guarantees no crooked situation then, through panel fixing structural panel is fixed on the workpiece fixed station 21 at last; Secondly, by the distribution of U type rib 1b U type rib 1b is placed on the panel 1a, and carries out the coarse positioning of U type rib 1b; Afterwards; Moving beam 4 is moved to the end of U type rib 1b, and zigzag crossbeam 3 presses down under the expansion regulating mechanism effect, and U type rib 1b accurately locatees down in 31 effects of zigzag crossbeam 3U type rib holddown groove; After zigzag crossbeam 3 presses down and puts in place; 1b positions weldering to U type rib, prevents the distortion of panel 1a, U type rib 1b in the tack welding process through the downforce of zigzag crossbeam 3, repeats above-mentioned tack welding until the location of accomplishing the whole length direction of U type rib 1b by certain spacing.Because U type rib 1b is through zigzag crossbeam 3 location, so positioning accuracy height and location efficiency height; Prevented the distortion in the tack welding process through downforce, therefore be out of shape little.
Position relation between above-mentioned workpiece fixed station 2 and the moving beam 4 can guarantee through frame, such as door type frame; Perhaps pass through basic guarantee.For simplified structure, in like the described instance of figure, said moving beam 4 is installed on the workpiece fixed station 2 through slide mechanism.
Because it is whole stressed bigger; In order to guarantee integrally-built rigidity; Thereby assurance positioning accuracy; In instance as shown in the figure, the two ends of corresponding moving beam 4 are respectively arranged with the track 51 that extends along moving beam 4 translation directions on the said workpiece fixed station 2, and said moving beam 4 two ends are respectively arranged with roller 52 and the rolling wheel support 53 that matches with respective carter 51; Be provided with anticreep position-limit mechanism and guiding mechanism between said moving beam 4 and the workpiece fixed station 2.Wherein guiding mechanism is in order to guarantee the direction of motion of moving beam 4, thereby guarantees the positioning accuracy on the whole length direction of U type rib; The anticreep position-limit mechanism then is to press down in the process at zigzag crossbeam 3, prevents to move on the moving beam 4, guarantees depressing of zigzag crossbeam 3.
Above-mentioned track 51 can adopt the rail system that carries limit function with roller 52, and such as grooved track and the roller that in groove, rolls, but it is comparatively complicated to carry the rail system structure of limit function; Secondly, in order to guarantee the stroke of zigzag crossbeam 3, rolling wheel support 53 is highly bigger, influences whole rigidity.Therefore, for simplified structure also guarantees integral rigidity simultaneously, said track 51 adopts the driving rails and is installed on the workpiece fixed station 2 through I shape track girder 54; Be provided with and lay respectively at I shape track girder 54 both sides and be fixed on the L type limiting plate 55 on the rolling wheel support 53; Web 54a, L type limiting plate 55 by I shape track girder 54 constitute the guiding mechanism that is slidingly matched, and constitute the anticreep position-limit mechanism by two supporting leg 54b, the L type limiting plate 55 at I shape track girder 54 tops.
Because the weld length of tack welding is usually at 50～100mm; Best; The axial length of said U type rib holddown groove 31 is 50～200mm, the width that reduces to reduce zigzag crossbeam 3 of U type rib holddown groove 31 axial lengths, and further effectively reduce the downforce that needs.Above-mentioned expansion regulating mechanism can adopt structures such as cylinder, hydraulic cylinder, screw mandrel, Holder for scissors; Distortion for fear of zigzag crossbeam 3; Best; Along zigzag crossbeam 3 axially zigzag crossbeam 3 is divided into n (n >=3) section, said expansion regulating mechanism comprises and is arranged on the n-1 on each equal branch (n >=3) part between zigzag crossbeam 3 two ends, the concrete quantity that is provided with is provided with according to zigzag crossbeam 3 length, width, material and the downforce requirement etc. of reality.In like the described instance of figure, concrete, the weld length of tack welding adopts 50mm, spacing 400mm; The axial length of said U type rib holddown groove 31 is 100mm, and as stated, it is axial that U type rib holddown groove 31 is axially perpendicular to zigzag crossbeam 3; Therefore; The width of zigzag crossbeam 3 is 100mm, length 6000mm, and said zigzag crossbeam 3 is divided into five sections, and said expansion regulating mechanism comprises and is arranged on four hydraulic cylinders 6 on each equal branch between zigzag crossbeam 3 two ends.
For further simplified structure and guarantee integral rigidity, said moving beam 4 adopts I-steel to process, and the position of said moving beam 4 corresponding expansion regulating mechanism each several parts is respectively arranged with strengthens gusset 41.Because moving beam 4 adopts I-steel, width is less, and in order to guarantee the support of moving beam 4, said moving beam 4 two ends are respectively arranged with two rollers 52, and each roller 52 corresponding position is respectively arranged with pair of L type limiting plate 55.
Further, said workpiece fixed station 2 is made up of the I shape workpiece beam 22 that is provided with at interval; Said panel fixing structural adopts U type card.
