Description
Technical Field
The invention relates to the technical field of building construction, in particular to a construction method for one-time pouring and forming of concrete flanging.
Background
Concrete flanges are generally treated to prevent rain from leaking into or to cover the top of the concrete flange or the edge of the concrete flange. In the traditional construction engineering, concrete flanging is performed in two ways, one is to support a template after floor slab pouring is completed and pour flanging is performed, but the combination of the new concrete surface and the old concrete surface is not compact enough, so that the problems of water seepage, water backflow and the like are easily caused in the engineering, and the water seepage causes serious mildew and other diseases. The other type is that the concrete flanging and the structural floor are constructed in one-step forming mode, although the waterproof capability of the concrete flanging can be ensured, the suspended mould is easy to run and expand, the fixing difficulty is high, and the precision is not suitable to be controlled.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a concrete flanging one-time pouring forming construction method which can form the concrete flanging one time, is beneficial to saving working procedures and improving construction precision and quality.
In order to solve the technical problems, the invention adopts the following technical scheme:
a construction method for one-time pouring and forming of concrete flanges is characterized in that a main structure template and main concrete ribs of a main structure are paved, measurement and paying-off are carried out on pouring positions of the concrete flanges to be poured according to a drawing, and a pouring construction area is determined; assembling a suspension mould for pouring the concrete flanging in the pouring construction area, and checking and accepting the suspension mould template; after the suspended formwork template is qualified, pouring the main structure, and pouring the turned edge within 20-30 minutes after the main structure concrete is poured; and removing the formwork after the concrete reaches the formwork removal strength.
Like this, pour the turn-ups in pouring 20 ~ 30 minutes after pouring the major structure, can make the concrete of major structure have certain intensity promptly, provide the support for the pouring of turn-ups. And the cast flanged concrete can be mixed with the concrete of the main body structure before solidification, so that the concrete is finally cast and molded at one time.
Further, the hanging die comprises a die plate assembly and a supporting assembly for supporting the die plate assembly, wherein the die plate assembly comprises side wall die plates positioned on two sides of the width direction of the flanging to be cast and a cross beam fixedly connected above the two side wall die plates; the supporting assembly comprises supporting ribs vertically arranged between the two side wall templates, the lower ends of the supporting ribs are fixedly connected to the concrete main ribs, the upper ends of the supporting ribs are fixedly supported below the cross beams, and at least two supporting ribs are arranged below each cross beam along the length direction.
In the structure, the supporting ribs are vertically fixed on the concrete main ribs, then the cross beam is supported on at least two supporting ribs, so that the cross beam and the side wall template connected with the cross beam can be fixed, the template running is prevented when concrete is poured, the construction precision is convenient to control, and the concrete forming quality is improved. After the concrete is formed, the supporting ribs are also solidified in the forming flanging, and because the supporting ribs are vertically arranged, the supporting ribs cannot transversely run through the flanging, so that water seepage at the joint of the supporting ribs and the concrete can be avoided, and the waterproof performance of the flanging is improved. Above-mentioned structural design is ingenious, and easy dismounting is convenient for realize the turn-ups and the integrative construction of pouring of floor main part, and the construction precision is high, is favorable to improving turn-ups waterproof performance.
Furthermore, the length of the cross beam is greater than the width of the flanging to be poured, the two ends of the cross beam extend to the outer side of the side wall template to form a cantilever, and an inclined strut which is obliquely arranged is connected between the cantilever of the cross beam and the lower end of the side wall template.
For guaranteeing the waterproof performance after the turn-ups shaping, when setting up the template, do not allow to use the wall and wear pull bolt or iron wire etc. to consolidate the template for the lower extreme of lateral wall template forms cantilever structure, and when concrete placement smashes, the lateral wall template can receive the extrusion of concrete, causes the lower extreme of lateral wall template outwards to expand and cause the mould that expands, influences construction quality. In the structure, the two ends of the cross beam extend outwards to form the cantilever, and the inclined strut is supported between the cantilever and the lower end of the side wall formwork, so that the strength of the lower end of the side wall formwork can be improved, the formwork expansion is prevented, and the construction quality is improved.
