[specific embodiment]
Below in conjunction with accompanying drawing the present invention is described in further detail:
With reference to figure 1, a kind of perforation is to drawing hinged-support type carriage, it is characterized in that: comprise drawing mechanism and i iron truss, the i iron truss is made of crossbeam steel 3 and supporting steel 4, described drawing mechanism is comprised upper to drawing mechanism 1 and lower to drawing mechanism 2, upper to drawing mechanism 1 two ends connecting cross beam steel 3, lower to connection supporting steel 4 lower ends, drawing mechanism 2 two ends, supporting steel 4 upper ends and 3 welding of crossbeam steel.
With reference to figure 2 and Fig. 3, described upper identical to drawing mechanism 1 or lower contraposition mechanism 2 structures, include steel pipe 5, steel plate 6, to pull bar 7 and steel hinged-support 8, described steel pipe 5 two ends are connected and fixed steel plate 6, described pull bar 7 is passed steel pipe 5, to pull bar 7 two ends by ground tackle 9 anchor connection steel hinged-supports 8.
With reference to figure 3 and Fig. 4, described steel hinged-support 8 comprises base plate 81 and flanged plate 82, and base plate 81 is provided with anchor hole 83, is provided with stiffening rib 84 between described base plate 81 and the flanged plate 82; With reference to figure 1, be provided with stiffener 10 between described crossbeam steel 3 and the supporting steel 4; With reference to figure 3, described pull bar 7 is made by fining twisted steel.
Referring to figs. 1 to Fig. 3, during construction, at pier shaft 11 interior embedded steel tubes 5, form the preformed hole that interts to pull bar 7.Steel pipe 5 two ends steel plates 6 one sides are installed pre-buried plastic foam plate, in order to form pit on the pier shaft surface.Adopt steel plate, i iron in advance at producer's processing hinged-support 8, and the triangle i iron truss of crossbeam steel 3 and supporting steel 4 welding formation.Behind the concrete casting complete of pier shaft top, stripping cuts the plastics vacuolar membrane, in 5 interior interting to pull bar 7 of embedded steel tube, under tower crane or crane cooperation, hinged-support 8 and triangle i iron truss are installed, and are laterally laid at a certain distance i iron, form the operation platform of 0# section.
Specific construction mounting method of the present invention:
1) hinged-support 8 and i iron truss processing and fabricating.
Such as Fig. 4, shown in Figure 5, hinged-support 8 is selected 20mm or 30mm Plate Welding processing and fabricating.
The i iron truss is that i iron and the welding of Two bors d's oeuveres channel-section steel are made, and is triangular in shape.The pin-and-hole position palpus employing of i iron truss and hinged-support 8 junctions is not less than the 10mm steel plate and reinforces.
2) built-in fitting and hinged-support are installed.
1. built-in fitting processing
As shown in Figure 2, built-in fitting is comprised of Φ 48 steel pipes 5 and 4mm steel plate 6 and plastic foam plate 12; Such as Fig. 2, shown in Figure 3, hinged-support 8 anchor systems and embedded part structure schematic diagram.
2. built-in fitting location positioning
Absolute altitude is determined: the absolute altitude position of installation of embedded parts is mainly considered the working space that the installation of beam body lower bolster needs and is decided, mainly considers following factor: a, shaped steel height; B, cushion block (vertical rod) are highly; C, template thickness; D, circuit longitudinal gradient; Working space that e, Hanging Basket bed die and longeron thereof, rear bottom rail joist steel are essential etc.
Horizontal level: the position of the upper and lower hinged-support embedded hole of each truss must remain on the same vertical curve, guarantees that each English truss is on the same vertical plane.
3. built-in fitting is located
For making things convenient for built-in fitting pre-buried, then the position of welding short steel rod location pre-embedded block on pier body formwork is welded in pre-embedded block steel plate point on the spacer bars first, and the reinforcement of weld reinforcing bar was fixed after the installation embedded steel tube was finished.
3) hinged-support 8, i iron truss and i iron distribution beam 13 are installed.
As shown in Figure 1, pier body formwork can cut pre-buried plastic foam plate 12 after removing, and namely forms the square pit that hinged-support 8 is installed after cutting, and checks location, spacing and the size of square pit, and the good hinged-support of prior processing and fabricating is installed.
Shown in Fig. 1,3,5, the i iron truss is by pin and hinged-support 8 bolts, and inspection, adjustment are fixed pin and flanged plate 82 after finishing with the spot welding form, prevent from becoming flexible, deviating from the construction.After the truss installation, lay i iron distribution beam 13, by reasonable distance i iron distribution beam 13 direction across bridge are arranged on the truss, but spot welding is fixed or adopted U-shaped spiral shell to fix between i iron distribution beam 13 and the truss i iron.
Fining twisted steel perforation of the present invention has been saved material to greatest extent to drawing hinged-support type carriage to possess very strong supporting capacity, and the pit design of hinged-support place pier shaft has guaranteed the attractive in appearance of pier shaft.Fining twisted steel passes pier shaft to drawing hinged-support, and the two pier outside shelf brackets of thin-walled and two pier intermediate bracket are coupled together, and has formed constitutionally stable integral body.
It should be noted that at last: above-described embodiment only is for example of the present invention clearly is described; and be not restriction to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here need not also can't give all embodiments exhaustive, and the apparent variation of being amplified out thus or the change still be among protection scope of the present invention.
