Abstract
The utility model discloses a foam truss-type internal mold combined structure for a highway box grider, which comprises a steel box and a foam circular plate, wherein a beam body is poured outside the foam circular plate; an end support frame supports the rear end of the steel box, and comprises end support legs and lifting jacks supporting the bottom surface of the steel box; middle support legs are hinged to the middle of the steel box; and a U-shaped clamping groove is connected to the front end of the steel box. According to the characteristics of foam and steel, the foam truss-type internal mold combined structure provided by the utility model is wider in application range; and the consumption of foam can be reduced greatly, so as to reduce construction cost.
Description
Technical field
The utility model relates to the little box girder construction of highway, more specifically says the little box girder inner formwork design of highway, also can be applicable to the plate-girder construction simultaneously.
Background technology
In China, country strengthens the capital construction to western remote mountain areas at present, and highway is fast-developing, wherein the beam prefabricated larger proportion that occupies in highway construction of the little case of highway.Because of little case beam end than middle part Concrete Thick, can not realize the overall steel moulding/demoulding, so can not adopt the monoblock type punching block to construct.The existing beam prefabricated internal mold of little case special detachable template or the foams of adopting more, special detachable template links to each other with buckle each other, support is established in inside, because the little case beam of highway inner chamber height generally is not more than 70cm, so the operating personnel is in the extremely inconvenience of little case beam inside processing.If inside molding plate does not adopt foam entirely, because foam can not be reused, construction cost is large.
At present, mainly there is following problem in the little box girder inner formwork construction method of traditional highway:
1. little case beam built-in function narrow space, inconvenient operation, and operating environment is poor;
2. the control of internal mold absolute altitude is difficult, and usually precision is difficult to guarantee;
3. inner formword adopts special detachable template, and the multi-block buckle links to each other each other, and form removal inconvenience is time-consuming;
4. adopt foam as inside molding plate, although can improve operating personnel's operating environment, foam can not reuse, and it is larger to cause construction to drop into.
The utility model content
The utility model is for the deficiency of avoiding above-mentioned prior art to exist, utilizes foam and steel self structure characteristics, and a kind of applicable wider a kind of highway case beam foam truss-like internal mold modular design is provided, and can greatly reduce the use amount of foam, reduces construction cost.
The technical solution adopted in the utility model is as follows:
A kind of highway case beam foam truss-like internal mold combining structure, include steel case, foam ring flat-plate, the foam ring flat-plate outside is cast with the beam body, the rear end of described steel case is supported with the end bracing frame, the end bracing frame is to place the jack on the steel case bottom surface to consist of by end supporting leg and holder, the middle part of steel case is hinged with middle supporting leg, and the front end of steel case is connected with U-shaped draw-in groove.
The two ends of described steel case are respectively equipped with level(l)ing bubble.
Described foam ring flat-plate is made of four blocks of cystosepiments.
Utilize highway case beam foam truss-like internal mold combining structure construction method, include following construction procedure:
A, colligation beam body reinforcing bar on pedestal at first, this moment is with foam ring flat-plate and the combination of steel case, the foam ring flat-plate divides four blocks of cystosepiments, adopt pressure sensitive adhesive double coated connection between every block of cystosepiment, cystosepiment is fixing to carry out the steel case after complete and moves, move by end bracing frame and the common supporting steel case of middle supporting leg, when central supporting leg moves to the pedestal edge, middle supporting leg has hindered the steel case and has moved, so need middle supporting leg rotation is packed up, continue to promote the steel case and move ahead, two steel casees are fast mobile when in place, U-shaped draw-in groove in the middle of the steel case is aimed at, realized the docking of steel case;
B, then adjust steel case absolute altitude, absolute altitude is by adjusting two ends jack control steel case absolute altitude, and whether level is consistent to check both sides steel case by level(l)ing bubble, adjusts to carry out end head formwork after complete also casting beams body concrete is installed;
C, carry out form removal construction at last, the beam body is built and is waited and carries out internal mold after strong and remove, and directly passes through hoist engine direct pull both sides steel case, treats that the steel case pulls out Liang Tishi soon, puts down middle supporting leg, again the steel case is pulled out the beam body fully.

The specific embodiment
Referring to accompanying drawing, a kind of highway case beam foam truss-like internal mold combining structure, include steel case 3, foam ring flat-plate 2, foam ring flat-plate 2 is made of four blocks of cystosepiments, and foam ring flat-plate 2 outsides are cast with beam body 1, and the rear end of steel case 3 is supported with the end bracing frame, the end bracing frame is to place the jack 5 on steel case 3 bottom surfaces to consist of by end supporting leg 4 and holder, the middle part of steel case 3 is hinged with middle supporting leg 7, and the front end of steel case 3 is connected with U-shaped draw-in groove 8, and the two ends of steel case are respectively equipped with level(l)ing bubble 6.
A kind of highway case beam foam truss-like internal mold combining structure construction method of utilizing includes following construction procedure:
A, colligation beam body reinforcing bar on pedestal at first, this moment is with foam ring flat-plate and the combination of steel case, the foam ring flat-plate divides four blocks of cystosepiments, adopt pressure sensitive adhesive double coated connection between every block of cystosepiment, cystosepiment is fixing to carry out the steel case after complete and moves, move by end bracing frame and the common supporting steel case of middle supporting leg, when central supporting leg moves to the pedestal edge, middle supporting leg has hindered the steel case and has moved, so need middle supporting leg rotation is packed up, continue to promote the steel case and move ahead, two steel casees are fast mobile when in place, U-shaped draw-in groove in the middle of the steel case is aimed at, realized the docking of steel case;
B, then adjust steel case absolute altitude, absolute altitude is by adjusting two ends jack control steel case absolute altitude, and whether level is consistent to check both sides steel case by level(l)ing bubble, adjusts to carry out end head formwork after complete also casting beams body concrete is installed;
C, carry out form removal construction at last, the beam body is built and is waited and carries out internal mold after strong and remove, and directly passes through hoist engine direct pull both sides steel case, treats that the steel case pulls out Liang Tishi soon, puts down middle supporting leg, again the steel case is pulled out the beam body fully.
So far, unjointed beam body casting process finishes, and can repeat construction, finishes until case is beam prefabricated.
