Description
Technical field
The falsework of wing plate during the utility model relates in the superimposed bridge construction of a kind of steel reinforced concrete.
Background technology
At present, in the construction of steel reinforced concrete superposed beam, the formwork for placing of wing centre section board concrete usually uses and lands all round victory rack form or the anti-template of hanging above steel case beam, but cross a river or stride promptly has the bridge construction of top, traffic route not possess the condition of floor stand, and floor stand uses material more, and cost is higher relatively.Be difficult for guaranteeing and hang mould mode construction quality, and concrete coating moulding meeting is produced many interference.
The utility model content
The utility model provides wing plate construction formwork support in a kind of steel reinforced concrete superposed beam, solve existing templates supporting structure complexity, cost height, and the construction quality technical problem that is difficult to guarantee.
The technical scheme that its technical problem that solves the utility model adopts is:
Wing plate construction formwork support in this steel reinforced concrete superposed beam, comprise the support body that is supported in below the wing centre section template die plate, it is characterized in that: described support body comprises two Pin supports at least, every Pin support is by a cross tube, left side hound, right hound and sheer pole are formed by connecting, cross tube be arranged at wing centre section template die plate under, the two ends of every cross tube are by bolt, fixedly connected below the upper flange of nut and steel case beam, the following middle part interconnection of every cross tube is across bar, left side hound and right hound are Λ shape, its upper end is connected with intersection point across bar with cross tube, the lower end of left side hound and right hound is supported in respectively on the lower flange of both sides steel case beam, the both ends of sheer pole respectively with the lower end interconnection of left hound and right hound, also be fixed with left connecting rod and right connecting rod between the left hound of adjacent support and between the right hound of adjacent support.
Can be lined with thickness adjusting plate between the middle wing plate of above-mentioned cross tube end face and steel case beam.
Can be provided with between above-mentioned cross tube and the steel case beam and wing centre section template die plate thickness corresponding thickness adjustable plate.
Be provided with pad between above-mentioned bolt and the cross tube.
Can link by the U-shaped bolt between above-mentioned left hound, right hound and the cross tube and connect.
Above-mentioned cross tube can be i iron, channel-section steel or square steel.
The beneficial effects of the utility model are as follows:
1, adopts the falsework form, compare the saving lot of materials, especially in the cross-line bridge construction of cross a river bridge or heavy traffic, solved effectively not have and landed the difficult problem of supporting condition with the console mode falsework.Previously used relatively top is hung mould and has been reduced and hang the influence that die body system builds bridge concrete, and the template deflection deformation reduces greatly.
2, use material to be on-the-spot versatile materials such as small bore i iron and scaffolding steel pipe, easy being easy to get, reusable, save cost.
3, set up conveniently, a dead lift can be in place on steel case beam wing plate to the installation place, need not auxiliary temporarily scaffold.
4, the dismounting that can on falsework, regress after the concreting maintenance is finished, removing does not need auxiliary temporarily scaffold, set bolt from bridge down the step can unloading remove, nut and plastic cap are retained in the concrete, and concrete quality is not produced any influence.
5, save material, save the space, compliance is strong, and safe ready is removed in assembling, and concrete pouring construction is effective.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Reference numeral: 1-waits to build the right hound of wing centre section plate, 2-wing centre section template die plate, 3-cross tube, 4-pad, 5-bolt, 6-nut, the trapezoidal stupefied wood of 7-template, 8-thickness adjusting plate, 9-steel case beam, 10-right connecting rod, 11-, 12-buckles across bar, 13-left side hound, 14-left side connecting rod, 15-sheer pole, 16-U shape bolt.
The specific embodiment
Embodiment is referring to shown in Figure 1, wing plate construction formwork support in this steel reinforced concrete superposed beam, comprise the support body that is supported in below the wing centre section template die plate 2, described support body comprises two Pin supports at least, every Pin support is by a cross tube 3, left side hound 13, right hound 11 and sheer pole 15 are formed by connecting, cross tube 3 can be an i iron, cross tube 3 be arranged at wing centre section template die plate 2 under, the two ends of every cross tube 3 are by bolt 5, fixedly connected below the upper flange of nut 6 and steel case beam 9, be provided with between the middle wing plate of above-mentioned cross tube 3 and steel case beam 9 and wing centre section template die plate thickness corresponding thickness adjustable plate 8.
Be provided with pad 4 between bolt 5 and the cross tube 3.The following middle part interconnection of every cross tube 3 is across bar 12, left side hound 13 and right hound 11 are Λ shape, its upper end is connected by U-shaped bolt button 16 with intersection point across bar 12 with cross tube 3, the lower end of left side hound 13 and right hound 11 is supported in respectively on the lower flange of both sides steel case beam 9, the both ends of sheer pole 15 respectively with the lower end interconnection of left hound 13 and right hound 11, also be fixed with left connecting rod 14 and right connecting rod 10 between the left hound 13 of adjacent support and between the right hound 11 of adjacent support.
