The specific embodiment
As shown in Figure 1 to Figure 3, the guiding device of assembling spatial diagonal web member of the present invention is installed in the steel truss girder lower chord gusset plate outside when using, comprise installation and positioning structure and directive wheel stretching structure.Installation and positioning structure includes location-plate 1, and front portion, location-plate 1 left side is fixed with left fill plate 2, is fixed with lower chord node dividing plate clamp 3 on the left fill plate 2, and location-plate 1 right side is fixed with right fill plate 4, is fixed with lower chord gusset plate clamp 5 on the right fill plate 4.The directive wheel stretching structure comprises parallel a pair of left fixed head 6 and a pair of right fixed head 7 that is welded on location-plate 1 top side by side, and the anterior corresponding position of each fixed head all level is provided with elongated sliding support hole 8, is equipped with bearing pin 9 in the elongated sliding support hole 8.Hinged respectively left directive wheel 11 and the right directive wheel 13 of being provided with on the bearing pin 9 on the bearing pin 9 between two left fixed heads 6, between two right fixed heads 7, on the bearing pin 9 of directive wheel 11 both sides, a left side, be installed with baffle plate 14 respectively on the bearing pin 9 of right directive wheel 13 both sides, the bottom of described baffle plate 14 all exceeds 3.0 ± 0.5 centimetres on described location-plate 1 top, the thickness of described baffle plate 14 must not occupy web member assembly unit space in place all less than the thickness of lower chord gusset plate; Between the baffle plate 14 of a left side directive wheel 11 and its both sides, be equipped with the gap between the baffle plate 14 of right directive wheel 13 and its both sides, all the spacing of two side shields 14 is little 0.5 centimetre separately than it for the thickness of left and right directive wheel 11,13.The rear end of described left and right two pairs of fixed heads 6,7 is connected and is provided with strut 15, the left and right sides of strut 15 is bolted with a left side respectively and regulates bolt 16 and the right bolt 17 of regulating, the front end of described left and right adjusting bolt 16,17 welds respectively and is provided with left sleeve pipe 18 and right sleeve pipe 19, and left and right sleeve pipe 18,19 equal fixed covers are located on the described bearing pin 9.Wherein, left and right adjusting bolt 16,17 is full silk bolt; Described location-plate 1 is provided with and dashes nail preformed hole 21.Described left and right directive wheel 11,13 is the nylon directive wheel; Between described two left fixed heads 6, all being connected between described two right fixed heads 7 is provided with stiffener 22; The internal diameter of left and right directive wheel 11, the 13 all diameter with bearing pin 9 is identical, is convenient to directive wheel around bearing pin 9 rotations.
The present invention is installed in the steel truss girder lower chord gusset plate outside, construction as follows during use:
1, hangs with the manpower lever guiding device of the present invention is hung the stressed cant board of lower chord node, baffle plate 14 retainings are at the gusset plate upside, lower chord node dividing plate clamp 3 is stuck on the lower chord node central dividing plate, lower chord gusset plate clamp 5 is stuck in lower chord gusset plate downside, finishes fixing guiding device of the present invention.
2, gantry crane lifting web member, the web member lower end contacts with the left and right directive wheel 11,13 of guiding device earlier, wouldn't meet touch hot aluminium-plated of lower chord gusset plate, avoids hot aluminium-plated face to be bruised.
3, stride the traveling of beam loop wheel machine overhead traveling crane by gate-type, web member is tilted, guarantee that its gradient is identical with the gradient of lower chord gusset plate.
4, twist left and right adjusting bolt 16,17 by pine, the polyester directive wheel makes the gap of both sides between web member and lower chord gusset plate suitable, avoids wearing and tearing in the web member dropping process hot aluminium-plated.
5, web member falls along the nylon directive wheel, on the lower chord gusset plate, look for a suitable eyelet as the rotating shaft eyelet, when corresponding eyelet overlaps with this eyelet on the web member, install one and liquidate nail (on inside and outside side gusset plate, respectively establish, and coaxial line) as the web member turning cylinder towards following closely.
6, the girder erection crane of walking about, rotate web member, lower chord is overlapped with other eyelets of web member position of joints, by standard according to the construction character according to corresponding code requirement, as in the construction of railway bridge, should observe " passenger dedicated railway line construction of bridge and culvert inspection of quality tentative standard " (No. [2005] 160, iron construction) } require to install all the other towards nail and general bolt.
Should be noted that in the construction that location-plate 16 must not occupy the eyelet of whole high-strength bolts of gusset plate, so that web member when location installs and dash nail.
Certainly, the present invention includes but be not limited to present embodiment, the mode of various equivalent transformations, as strut 15 is replaced with fagging, or the like, this type of conversion all drops within protection scope of the present invention.
