Further, in the step (5), the formwork removal of the hanging formwork is carried out only after the strength of the poured concrete reaches a strength capable of passing people.

Compared with the prior art, the present invention has the following beneficial effects:

(1) The present invention has high dimensional accuracy, and the mold adopts thin-walled rectangular steel pipe, which is light in weight, connected by bolts, easy to connect, convenient to use, install and disassemble.

(2) The present invention adopts a specially designed base for cement mortar molds, controls the installation height of the mold through the base for cement mortar molds, and controls the vertical and horizontal positions of the plane according to the vertical and horizontal position lines. The installation position is accurate and precise, and it is firmly installed without displacement.

(3) The present invention uses rectangular steel pipes to make modular hanging molds. This mold not only has a high reuse rate, but also can be adjusted and modified into a new mold in other projects, and can be reused again, which significantly reduces the consumption of formwork materials in the kitchen and bathroom. Construction costs.

The names corresponding to the reference signs in the accompanying drawings are as follows: 1-rectangular steel pipe, 2-base for cement mortar mould.

detailed description

The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

Example

In the traditional construction method of civil building kitchen and bathroom construction, wooden formwork is used as hanging formwork, which is not only inconvenient for construction, but also has poor stability, less repeated use times, and high construction cost. In order to solve this technical problem, as shown in Figure 1, this embodiment provides a construction method based on the sinking type hanging mold for the kitchen and bathroom of civil buildings. Stencil mold. Its installation and disassembly are simple and fast, its position is fixed accurately, it can be reused, and it can also be refitted and used in other projects, which significantly reduces the cost of hanging formwork in the kitchen and bathroom. This method adopts modular technology, and uses thin-walled rectangular steel pipes to make hanging formwork molds. The rectangular steel pipes are connected by bolts, thereby realizing fast and convenient installation and disassembly of the molds. The resource is saved, and it is beneficial to reduce the construction cost.

In order to make those skilled in the art have a clearer understanding and understanding of the present invention, the following in conjunction with specific description:

This method mainly includes the following steps:

1. The steps of making modular hanging molds with rectangular steel pipes

The production of the mold adopts modular technology, and thin-walled rectangular steel pipes are used to make the hanging formwork mold, and the rectangular steel pipes are connected by bolts; specifically, in actual construction, according to the shape and size of the kitchen and bathroom, rectangular steel pipes of 50×80mm or more are used for processing Make the hanging module mold of the kitchen and bathroom, and the rectangular steel pipe of the mold is connected with bolts of M8×70mm or more.

2. The steps of prefabricating the base of the cement mortar mold

Prefabricate a special cement mortar base according to the thickness of the floor slab of the kitchen and bathroom, and its size is 50mm×80mm×the thickness of the floor slab. Place the mold on the base of the prefabricated cement mortar mold to meet and control the height requirements of the hanging formwork mold.

3. Steps for installation of sunken hanging mold

First place the prefabricated cement mortar base at a distance of about 1m-1.5m at the corresponding position of the floor formwork, assemble the rectangular steel pipes of the hanging mold mold one by one, install the assembled hanging mold mold on the cement mortar mold base, and adjust the hanging mold. The vertical and horizontal position of the mold is corrected, and the hanging mold mold is fixed on the bottom formwork of the kitchen and bathroom with φ1-2mm iron wires with a spacing of 1-2m. Among them, the vertical and horizontal position correction of the hanging formwork mold can realize the plane position control of the mold. According to the vertical and horizontal position lines placed on the floor and beam bottom formwork, the alignment position line is bound on the floor and beam bottom mold with iron wire to ensure its The plane position does not shift.

Fourth, the steps of pouring concrete

The pouring can be carried out according to the conventional concrete pouring method, which belongs to the conventional technology in this field, and will not be repeated here.

Five, the steps of mold removal

After the strength of the poured concrete reaches the strength that can be used by people, the formwork of the hanging formwork is removed. When removing the formwork, the rectangular steel pipes in the mold are removed one by one; after the removal of the formwork, the mold is cleaned and repeated for the next construction use.

According to the above-mentioned embodiments, the present invention can be well realized. It is worth noting that, based on the premise of the above-mentioned design principle, in order to solve the same technical problem, even if some insubstantial changes or modifications are made on the basis of the structure disclosed in the present invention, the essence of the adopted technical solution is still Like the present invention, it should also be within the protection scope of the present invention.
