The invention discloses a small box beam inner die and support frame capable of realizing rapid de-molding. The small box beam inner die and support frame is characterized in that a longitudinal horizontal center shaft is arranged between a bottom die and left and right side templates as well as a top die, wherein a plurality of groups of convex support points are arranged in sections on the longitudinal horizontal center shaft; three support rods are arranged on three convex support points respectively, the top die and the left and right side templates are arranged at the top ends of the three support rods respectively, and concave support points are arranged in the centers of the top die and the left and right side templates, so that the top die and the left and right side templates are integrated. No bolts are required to be assembled and disassembled on the templates, the mechanics principle of an arch ring is ingeniously utilized, the top die and the left and right side templates are employed as main support points of the arch ring, the support forces of the top die and the left and right side templates on the arch ring completely act on the longitudinal horizontal center shaft designed in the center of a circle, and the longitudinal position of the longitudinal horizontal center shaft in an inner cavity of a small box beam is horizontally shifted to change support angles of the support rods to force the spatial positions of the top die and the left and right side templates to be shifted, so as to realize rapid modeling and rapid de-molding, so that the advantages of reducing manual labor and improving working benefits are achieved.
Description
Technical field
The present invention relates to bridge beam slab preforming tool, is exactly a kind of small box girder internal mold and bracing frame of energy fast demoulding.
Background technology
At present, in the bridge construction of hinterland, design adopts the bridge of small box girder very general, particularly dark in those riverbeds, and water level is apart from the bridge of the not high bridge of bridge floor and a lot of urban road, and in order to increase flood carrying capacity under bridge, design adopts small box girder mostly.The length of general small box girder is between 20-25 meters, and the longest small box girder is 35 meters, and the height of small box girder is 1.2-1.5 rice, and an outage just 0.6-0.8 rice in beam slab, small box girder inner formword specification is generally 0.6 × 0.8 meter.The inner formword of small box girder comprises all polylith modules such as backform, bed die, left and right sides template, left and right corner top template and left and right corner end template, when traditional small box girder is prefabricated, all adopt bolt that these modules above-mentioned are connected into an entirety (as Fig. 1) one by one, until beam slab is prefabricated complete after, skilled worker is arranged to crawl in prefabricated beam slab from the port of beam slab, one one is unloaded bolt, then takes out template one by one.Because small box girder inner space is very narrow, the aperture, termination of beam slab is also less than beam slab inner space, skilled worker crawls into and climbs out of very difficult, unloads a bolt very very difficult thing especially inside, particularly hot summer and the winter of cold, operate this work very difficult thing especially, and work efficiency is very low, the prefabricated cycle stretch-out of beam slab, the form removal of beam slab is extremely inconvenient, some units in charge of construction also attempted some corrective measures, but effect is not clearly.
Summary of the invention
The object of the invention is to: small box girder internal mold and bracing frame that a kind of energy fast demoulding is provided, do not need to load and unload a bolt in template, use the mechanics principle of arch ring dexterously, by backform and the left and right sides template main support point as arch ring, by on completely stressed for its support force at the arch ring longitudinal horizontal central axle designed on the center of circle, by moving horizontally vertical central axis lengthwise position empty in small box girder, change the support angle of support bar, force backform and left and right sides template movement locus, reach the object of rapid modeling and fast demoulding.
the object of the invention is to realize by implementing following technical proposals:
The small box girder internal mold of energy fast demoulding and a bracing frame, be made up of backform, bed die, left and right sides template, left and right corner top template and left and right corner end template.It is characterized in that: in left and right sides template and be provided with longitudinal horizontal central axle between backform and bed die, subsection setup many groups convex strong point on longitudinal horizontal central axle, on longitudinal horizontal central axle, the corresponding backform direction of the convex strong point on edge is arranged, and under longitudinal horizontal central axle left and right sides, the convex strong point on edge is arranged in corresponding left and right sides template direction respectively; Three convex strong points are respectively arranged with three support bars, are respectively arranged with backform and left and right sides template on the top of three support bars, backform and left and right sides template central authorities are provided with the matrix strong point; The described matrix strong point is connected with longitudinal horizontal central axle respectively by three support bars with the convex strong point of three on longitudinal horizontal central axle, makes small box girder inner formword and bracing frame form an entirety.Between longitudinal horizontal central axle and bed die, arrange a movable push rod, described movable push rod lower end is erected on bed die, and edge under longitudinal horizontal central axle is withstood in upper end; Longitudinal horizontal central axle one end is provided with towing pad;
The termination of described support bar and movable push rod, is all set to the right right angle of the left fillet of upper end, the right fillet in the left right angle of lower end;
The termination of described small box girder backform, bed die, left and right sides template, left and right corner top template and left and right corner end template is provided with hasp, when being convenient to modeling between hasp the jointing material of cushioning one deck waterproof mud leakage;
The present invention does not need to load and unload a bolt in template, use the mechanics principle of arch ring dexterously, by backform and the left and right sides template main support point as arch ring, by on completely stressed for its support force at the arch ring longitudinal horizontal central axle designed on the center of circle, by moving horizontally vertical central axis lengthwise position empty in small box girder, change the support angle of support bar, force backform and left and right sides template movement locus, be convenient to rapid modeling and fast demoulding.
advantage of the present invention is: small box girder internal mold and bracing frame that a kind of energy fast demoulding is provided, do not need to load and unload a bolt in template, use the mechanics principle of arch ring dexterously, by backform and the left and right sides template main support point as arch ring, by on completely stressed for its support force at the arch ring longitudinal horizontal central axle designed on the center of circle, by moving horizontally vertical central axis lengthwise position empty in small box girder, change the support angle of support bar, force backform and left and right sides template movement locus, realize the advantage of rapid modeling and fast demoulding.
