Technical Field

The invention relates to the technical field of toilet sinking room construction, in particular to a construction method of a toilet sinking room in a building project.

Background

In the construction of a floor slab of a main body of a building at present, the sinking construction of a toilet is in heavy middle, the slab reinforcing bars of the floor slab and the toilet are bent and sunk during the construction of the main body or the sinking reinforcing bars of the toilet are prefabricated in advance, and then the concrete is poured through a wood square formwork. And when the formwork removing condition is reached after the pouring is finished, manually prying the batten (or the square steel) for formwork removal. This operating mode usually, the bathroom sinks to get the external corner and because of improper the not leakage hidden danger that has the different degree of dismantling the mould, still must carry out the secondary repair of sinking and bathroom waterproofing later stage and have the different degree before leading to the fact the anti-bank construction of later stage bathroom, need consume manpower, material resources and remove the secondary maintenance, cause construction cost to increase.

Disclosure of Invention

In order to solve the technical problem, the invention provides a construction method of a sinking toilet in a building project, which can prevent the external corner of the sinking toilet from being damaged and avoid secondary maintenance.

In order to realize the technical purpose, the invention adopts the following scheme: the construction method of the toilet sinking room in the house construction project comprises the following steps:

after the plate reinforcement construction of a toilet sink room is completed, placing prefabricated concrete cushion blocks at four corners of the toilet sink room respectively, wherein vertical steel bars are fixed at the upper ends of the cushion blocks, and the upper ends of the four vertical steel bars are connected in pairs through horizontal steel bars to form corner protection bar structures;

binding the inner sides of the corner protecting ribs by using steel wires to lower the reinforcing ribs of the intermediate plate;

step three, buckling battens or square steels on the reinforcing bars of the sinking compartment plate to perform formwork supporting and template internal reinforcing treatment after the construction of the embedded sinking compartment angle bead bars is finished, wherein formwork removing handles are arranged on the battens and/or the square steels;

step four, pouring concrete after the formwork is erected;

and step five, after the pouring is finished, when the concrete form removal condition is achieved, the batten and/or the square steel are lifted by the handle to carry out form removal, and the construction of the toilet sinking room is completed.

Compared with the prior art, the invention has the beneficial effects that: the method provided by the invention is simple to operate, the damage of the sinking room external corner during the form removal is effectively avoided by using the mode of embedding the corner protecting ribs and the template with the form removal handle, the problem of secondary repair of the sinking room external corner before the back ridge construction of the toilet is solved, the phenomenon of leakage hidden danger of different degrees in the later waterproof construction of the toilet is avoided, and the maintenance construction cost is saved.

Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the invention, but the present invention is not limited thereto.

The invention provides a construction method of a toilet sinking room in a building project, which comprises the following steps:

step one, after the construction of the plate reinforcing steel bars 1 required by the construction drawing is completed, prefabricated concrete cushion blocks (HRB 400 vertical reinforcing steel bars 4 are vertically inserted and fixed in the cushion blocks, the length of each vertical reinforcing steel bar 4 is determined according to the sinking height of a sinking room) are respectively placed at four corners of a toilet, the upper ends of the four vertical reinforcing steel bars 4 are connected in pairs through horizontal reinforcing steel bars 3 (HRB 400 reinforcing steel bars) to form sinking room external corner angle bead steel bars, and the angle bead steel bars are connected with the construction drawing plate reinforcing steel bars 1 through steel wire lines, as shown in figures 1 and 2.

And step two, after the construction of the pre-buried sunken intermediate angle bead is finished, inversely placing an open cuboid frame made of wood or square steel on the plate reinforcing bars 1 bound by the angle bead as a template 2, and performing formwork supporting treatment. When the formwork is erected, a plurality of diagonal braces are fixed inside the framework of the formwork 2, and the framework of the formwork is reinforced, as shown in fig. 4. A handle 5 is fixed to the upper end surface of the formwork 2, i.e., the bottom of the batten or square steel frame, as shown in fig. 3 and 4.

And step three, after formwork supporting is finished, concrete pouring is carried out.

And step four, after pouring is finished, when the concrete form removal condition is met, removing the form through the handle 5, protecting the external corner of the sinking chamber due to the fact that the angle bead ribs are embedded in the external corner of the sinking chamber, and replacing a form prying removal mode by using the handle 5 to remove the form, so that the external corner of the sinking chamber is protected, and damage is avoided.

The method of the invention has the following advantages: (1) the phenomenon that the hidden danger of leakage is caused to different degrees in the later stage of the sink external corner secondary repair and the waterproof construction of the toilet can be effectively avoided before the construction of the reverse ridge of the toilet. (2) The method is simple to operate, and avoids the increase of construction cost caused by the fact that manpower and material resources are consumed to carry out secondary maintenance in the later period. (3) The mode of pre-burying the corner protecting ribs and the batten (or square steel) with the formwork removing handle can effectively avoid the damage of the sinking external corner during formwork removing. (4) If square steel is utilized for formwork support, the formwork can be used in a circulating mode, and resources are saved.

Finally, it is noted that: the above-mentioned list is only the preferred embodiment of the present invention, and naturally those skilled in the art can make modifications and variations to the present invention, which should be considered as the protection scope of the present invention provided they are within the scope of the claims of the present invention and their equivalents.
