Description
Technical Field
The invention relates to a method for erecting a concrete template, in particular to a novel formwork method for a gutter in a pitched roof house.
Background
In modern house construction, a mode of erecting hanging molds on two sides of a side plate of a gutter is often adopted for the gutter part in a sloping roof, concrete of a bottom plate of the gutter needs to be poured in advance in the pouring process, the side plate needs to be poured after the concrete is initially solidified, if time control is not good, a cold joint is generated, water seepage risks easily occur at a joint part of the side plate and the bottom plate of the gutter in the later period, the pouring time is too long, and the labor cost is increased. Because the thickness of the bottom plate concrete is not controlled by the template in the concrete pouring process, the side form is reinforced under the influence of factors such as infirm, the forming quality effect of the gutter is poor, the bottom plate of the gutter is uneven, a large amount of manpower and material resources are needed to be secondarily repaired and leveled in the later period, and the defects that the whole forming quality effect is poor and the like exist.
The known methods of erecting a formwork sling for a gutter thus present the inconveniences and problems described above.

e. pouring concrete and dismantling the mould
After the concrete pouring is finished and a certain strength is reached, after the water stopping screw rod is cut off, the mould is integrally hoisted and dismantled through the lug plate fixed at the upper part of the mould by adopting a tower crane or other hoisting facilities;
f. reuse of gutter finished product mold in other gutter parts
And after the gutter finished product mold is disassembled, the gutter finished product mold is repeatedly used for construction of other gutter parts according to simple assembly.
The novel formwork method for the gutter in the pitched roof house can be further realized by adopting the following technical measures.
In the method, the thickness of the aluminum mold wall of the 1 st finished product is greater than or equal to 3 mm.
In the method, the thickness of the aluminum mold wall of the No. 2 finished product is more than or equal to 3 mm.
In the method, the thickness of the aluminum mold wall of the 3 rd finished product is more than or equal to 3 mm.
In the method, the diameter of the through hole is more than or equal to 14 mm.
The foregoing method, wherein the water stop bolts set the molds at a pitch of one per 500 mm.
After the technical scheme is adopted, the novel formwork method for the gutter in the pitched roof house has the following advantages:
1. the product is processed by a finished product aluminum mould, so that adverse effects caused by traditional supporting of a hanging mould can be better avoided;
2. the engineering quality is safe and reliable, and the construction progress is fast;
3. the mold can be reused, and the engineering cost is reduced.

Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The novel formwork erecting method for the gutter in the pitched roof house is completed after the steel bars of the bottom plate and the side plates of the gutter are bound in the construction process of the gutter. Referring now to fig. 1 and 2, fig. 1 is a schematic view of a gutter structure in a pitched roof house according to an embodiment of the present invention, and fig. 2 is a cross-sectional view a-a in fig. 1.
According to the design specification of a gutter node in a structural construction drawing, a side wall formwork supporting mode of a gutter is that a No. I finished aluminum mould (the thickness of 3mm is 500mmX100mmX200 mm) and a No. II finished aluminum mould (the thickness of 3mm is 500mmX200 mm) are assembled in a U-shaped buckle mode. Fig. 3 is an enlarged view of a portion P in fig. 2, where P is a structure of a finished aluminum mold of (r). FIG. 4 is an enlarged view of the portion Q in FIG. 2, wherein Q is the structure of the finished aluminum mold.
The mode of formwork support of the gutter bottom plate in the embodiment is that a No. finished product mould and a No. three finished product mould (the wall thickness is 3mm, the specification is 500mmX100 mm) are assembled in a U-shaped buckle mode. FIG. 5 is an enlarged view of the portion M in FIG. 2, where M is a third aluminum mold structure. Holes with the diameter of 14mm are reserved on the first die and the second die respectively, and the dies are fixed at intervals of 500mm by water stop bolts, so that the die is prevented from deviating due to lateral pressure of concrete in the pouring process. The length of the water stop screw is formed by welding according to the actual gutter size, the specification of the water stop screw is M12 type, and the size of the water stop sheet is 50mmX50 mm.
After concrete pouring is finished and certain strength is achieved, after the water stopping screw is cut off, the mould can be integrally hoisted and dismantled through the lug plates fixed on the upper part of the mould by adopting a tower crane or other hoisting facilities. After the assembly is disassembled, the assembly can be applied to construction of other gutter parts according to simple assembly.
Compared with the traditional mode (namely, the side wall of the gutter is hung to finish the fabrication of the gutter), the novel formwork method for the gutter in the pitched roof house has the advantages that the flatness forming effect of the bottom and the side wall of the gutter is good after the concrete pouring is finished, the pouring time is saved in the pouring process, the side plate concrete does not need to be poured after the bottom plate concrete is initially set, and the one-step forming waterproof quality effect is good. The finished product die can be repeatedly utilized, and accords with the green construction idea.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Accordingly, all equivalents are intended to fall within the scope of the invention, which is defined in the claims.
