Abstract
The utility model discloses a horizontal supporting structure of a building formwork. A back ridge which is perpendicular to a lateral wood beam is arranged outside the wood beam of an outer side face of the formwork in each direction respectively; two back ridges outside the formwork of every two adjacent side faces are connected through a pin; each back ridge is connected with a steel rib in the formwork through a pull rod; one end of the pull rod is connected with the steel rib in the formwork, and the other end of the pull rod, i.e., the end which is not connected with the steel rib, penetrates through a gap between the formwork and the wood beam to be connected with the back ridge; the pull rod penetrates through a through hole and is fastened through a nut; and a counter pull rod is arranged in the space between every two opposite back ridges apart from the steel rib. Compared with the prior art, the horizontal supporting structure has the advantages of uniform and rational stressing, low probability of deformation of the formwork, capability of reducing the occurrence rate of a building accident and the like.
Description
Technical field
The utility model belongs to the realm of building construction, relates in particular to a kind of horizontal support structure of construction formwork.
Background technology
At the realm of building construction, construction formwork has become the important tool of concrete structure engineering construction, in the cast-in-place concrete structure engineering; Form work engineering generally accounts for 20%～30% of concrete structure engineering cost; Account for 30%～40% of the engineering amount of labour used, account for about 50% of the duration, so; Mould plate technique directly influences quality, cost and the benefit of engineering construction, so it is an important content that promotes China's Building technology progress.
At present; Do not contain the concrete building template of reinforcing bar for some inside, its braced structures generally adopts flitch as perpendicular stupefied, and round steel pipe is as back cord; Flitch is supported on the outside of template; Round steel pipe is supported on the outside of flitch, link to each other through split bolt between two round steel pipe of each opposite face outside of template, and split bolt passes, and template is inner to be formed drawing.This bolt can be accomplished support and reinforcing to template to the mode of drawing, but because the bolt of this structure is to pass that template is inner to be formed drawing, so the mixed pise template that contains reinforcing bar for inside then can not be suitable for.
At present, the braced structures that contains the mixed pise template employing of reinforcing bar for inside mainly is a steel truss, because of template contains reinforcing bar; Split bolt can't pass reinforcing bar; The longitudinal bracing of the then inner mixed pise template that contains reinforcing bar is promptly perpendicular stupefiedly still to adopt flitch, and the support of horizontal direction adopts steel truss as back cord, and promptly flitch utilizes steel truss to support outward; Adopt reinforcing bar as pull bar between the truss; Form between the relative truss pull bar, adjacent and become to form external corner between the truss of angle and tiltedly draw, but pull bar is arranged on the outside of template.Though the mixed pise template that this structure contains reinforcing bar to inside has played the horizontal support effect, in practice of construction, exists following deficiency:
1, because reinforcing bar is contained in template inside, so the steel bar rod between the truss just carries out drawknot in the outside of template and the outside of truss, inside has no drawknot; And the distance between the pull bar is excessive, because the shape of construction formwork is different, causes the truss discontinuity in the practice of construction; Importantly in the process of the inner fluid concrete of template; Angle between the truss very easily is out of shape, thereby causes template deformation, and the accident of the quick-fried mould of concrete very easily takes place template deformation.
2, because the weight of truss is big, single truss all brings difficulty in work progress, for workman's carrying and installation basically more than hundred kilograms.
3, the cost of truss is bigger, and recycling rate of waterused is low.
Summary of the invention
It is a kind of not only stressed even, reasonable that the purpose of the utility model is to provide, and template is not yielding, reduce the building accident rate, and construction cost is low, and recycling rate of waterused is high, the construction formwork horizontal support structure of raising efficiency of construction.
The technical scheme that the utility model adopted is that the building that contains reinforcing bar in inside for example is provided with back cord outside the outside longitudinal bracing flitch of template such as body of wall, huge post; The flitch that is the template lateral surface of each direction is respectively equipped with a back cord vertical with this side rail side outward; This back cord can be channel-section steel, square steel pipe or i iron; But more firm for reaching support, stressed purpose more uniformly, back cord is channel-section steel preferably; Link to each other through pin or bolt between two back cords outside the template of above-mentioned every adjacent two sides; Above-mentioned every back cord is connected with the inner reinforcing bar of template through pull bar; Said pull bar is that two ends have externally threaded reinforcing bar; This pull bar one end links to each other with reinforcing bar in the template; Its connected mode can be on reinforcing bar, to offer and the corresponding screw thread slotted eye of pull bar one end external screw thread, and pull bar links to each other with reinforcing bar through the screw thread slotted eye on the reinforcing bar; Connected mode also can be a welded sleeve on reinforcing bar; The machined of this sleeve and the corresponding internal thread of pull bar one end, pull bar links to each other through the sleeve on the reinforcing bar, damages reinforcing bar for reducing; And easy construction, pull bar are preferably adopted through the sleeve on the reinforcing bar and are linked to each other with reinforcing bar; The other end of pull bar is that the slit that disconnected reinforcing bar end passes between template and flitch links to each other with back cord, promptly offers the through hole corresponding with the size of pull bar on the back cord, and pull bar passes this through hole and fastening through nut; Pull bar between back cord outside above-mentioned each side and this side direction reinforcing bar is at least one, and can require the quantity of adjustment pull bar according to practice of construction; Above-mentioned per two relative back cords and between them the space except that reinforcing bar also be provided with pull bar, promptly to pull bar, the through hole on the back cord of both sides is passed at these two ends to pull bar, and fastening through nut.
The utility model is arranged on the promptly perpendicular stupefied outside of longitudinal bracing flitch, and the building that reinforcing bar is contained in inside for example template such as body of wall, huge post play the horizontal support effect, back cord supports and template inside has pull bar; When in template, watering concrete; Guaranteed the stability of template, the quantity of pull bar and the spacing between the pull bar can be according to the adjustment of practice of construction demand, and back cord is accepted evenly; Template is not yielding, thereby lowers the generation of quick-fried mould accident; The utility model can have pvc pipe at rod outer sleeve when mounted, treat that concrete pouring is accomplished after, pull bar can withdraw from repeated use, has reduced cost of production; In addition, back cord adopts channel-section steel, square steel pipe or i iron, and these steel relative weights are light, and price is low, and is easy for installation.
The utility model compared with prior art has following advantage:
1, structure stress is even, reasonable, and template is not yielding, reduces the building accident rate;
2, cost is low, and is easy for installation, and recycling rate of waterused is high, improves efficiency of construction.
