Description

The present invention relates to a method for constructing an industrialized house, and can be used for assembling an industrialized house composed of a plurality of house units.

[Background Art] In recent years, after each component of a house is manufactured as a housing unit by improvement, an industrialized house is constructed in which these housing units are mounted on a truck or the like and transported to a construction site to assemble each housing unit. It is becoming.

Conventionally, when assembling a housing unit, in the case of rainy weather, the assembly has to be stopped in order to prevent rainwater from entering the inside of the housing unit. in this way,
If the assembly of the housing unit is affected by the weather and the length of rainy weather is prolonged, there is a problem that the construction period is delayed, which in turn affects the construction cost.

In addition, during construction, if there is no room to hang a waterproof sheet and the weather suddenly becomes rainy, rainwater may enter the interior of the housing unit.

Then, the present applicant, in order to solve the above problems,
In Japanese Patent Application No. 1-159295, a step of coating a housing unit with a transparent waterproof sheet at a building site or a factory, a step of assembling a housing unit covered with the waterproof sheet, and a step of removing the waterproof sheet are described. We proposed a method of constructing an industrialized house, and made it possible to assemble a house unit even in rainy weather.

[Problem to be Solved by the Invention] According to the method for constructing an industrialized house proposed by the present applicant, for example, in assembling a two-story house unit, after installing the first-floor house unit, the second-floor house unit If it suddenly becomes rainy before installation, the installation work on the second-floor housing unit cannot be performed unless the rainwater accumulated on the upper surface of the waterproof sheet covered by the first-floor housing unit is removed. As shown in FIG. 7, the housing unit 11 has a structure material 21 that is exposed, and the rainwater 22 is easily accumulated on the upper surface.
Workers have to lift by hand on the upper surface of the tarpaulin 12 so that the 22 flows out of the upper surface of the tarpaulin 12, which is troublesome and involves work in the rain, which is dangerous. Was.

An object of the present invention is to provide a construction method of an industrialized house that can easily remove rainwater accumulated on the upper surface of a waterproof sheet covered by a housing unit.

Means for Solving the Problems The present invention has a step of covering a housing unit with a transparent waterproof sheet, a step of assembling a housing unit covered with the waterproof sheet, and a step of removing the waterproof sheet. In the method for constructing an industrialized house, a water absorbing material is laid on an upper surface of the waterproof sheet, the absorbing material that has absorbed rainwater is removed, and the assembling work of the house unit is continued.

As the water-absorbing material, for example, a starch-acrylic acid graft copolymer known as a super water-absorbing resin in the form of a sheet can be arbitrarily used.

The transparent waterproof sheet includes a translucent waterproof sheet.

As a material of the waterproof sheet, various waterproof synthetic resins such as polyvinyl chloride and polyethylene can be arbitrarily used.

[Operation] For example, after installation work of the first-floor housing unit, it suddenly becomes rainy, and when continuing the assembling work of the second-floor housing unit, it is laid on the upper surface of the waterproof sheet of the first-floor housing unit, and rainwater The assembly work is continued after removing the water-absorbing material that has absorbed the water.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

First, as shown in FIG. 1, a housing unit 11 which is a component of a house is manufactured in a factory, and then a transparent waterproof sheet is formed. For example, a vinyl sheet 12 is coated. The vinyl sheet 12 has a box shape so as to cover the entire top and side surfaces of the housing unit 11. In addition, this vinyl sheet 12 has a surface which is subjected to anti-slip processing by, for example, parallel uneven portions on the surface for safety when a worker rides on the housing unit 11 at the building site and performs assembly work. use. It should be noted that the housing unit 11 in FIG.
Only residential units are shown.

Next, as shown in FIG. 2, the housing unit 11 covered with the vinyl sheet 12 is placed on a truck 13 and transported to a predetermined building site.

Next, as shown in FIG. 3, at the construction site, the housing unit 11 on the first floor is lifted by a crane (not shown) and installed at a predetermined position. Thereafter, when it is likely to be rainy, a sheet-like water-absorbing material 17 made of a highly water-absorbent resin is laid on the upper surface of the vinyl sheet 12 of each housing unit 11 on the first floor.

Next, after the installation work of the first-floor housing unit 11, it suddenly rained, and when continuing the assembling work of the second-floor housing unit 11, as shown in FIG. After removing the water-absorbing material 17 laid on the upper surface of the vinyl sheet 12 and absorbing rainwater, the house unit on the second floor is removed.
Continue the assembly work of step 11. As shown in the figure, even if the vinyl sheet 12 sags along the shape of the structural material 21, the rainwater is absorbed by the water absorbing material 17 laid thereon, so that the rainwater does not accumulate on the vinyl sheet 12. Absent.

Next, as shown in FIG. 4, chains 14 are hung on locking members provided at the four corners of the housing unit 11 on the second floor, lifted up by a crane (not shown) via these chains 14, and installed at a predetermined position. . In a state where the vinyl sheet 12 is covered with the unit 11, the vinyl sheet 12 of the portion where the work such as bolting is performed is broken, and a connection between the respective housing units 11 and a mounting of the eave 15 shown in FIG. Perform assembly work.
During the assembling operation, if the wind is strong and the vinyl sheet 12 may fly, it is better to cover the vinyl sheet 12 from above.

Next, as shown in FIG. 5, after the assembly is completed, the vinyl sheet 12 covered by each housing unit 11 is cut off with a cutter or the like and removed. At this time, between the housing units 11,
In some cases, the vinyl sheet 12 remains without being removed, but it remains in a place hidden from the surface, which is aesthetically acceptable.

According to the above embodiment, after the installation work of the first-floor housing unit 11 suddenly becomes rainy and the assembling work of the second-floor housing unit 11 is continued, the first-floor housing unit 11 is continued.
The removal of rainwater accumulated on the upper surface of the vinyl sheet 12 can be easily performed by removing the water absorbing material 17 laid on the upper surface of the vinyl sheet 12 and absorbing the rainwater. It is.

Further, in the present embodiment, since the water absorbing material 17 is laid beforehand when it is likely to be rainy, as in the case of laying after rainy weather, the rainwater collected on the vinyl sheet 12 according to the uneven shape of the upper surface of the housing unit 11 is removed. This eliminates the need to press the water-absorbing material 17 by hand to absorb water, thereby reducing the work.

Further, the sheet-like water-absorbing material 17 used in the present embodiment is made of a highly water-absorbing resin, for example, 60 / m ²
Rain water that has fallen on the upper surface of the vinyl sheet 12 of the first-floor housing unit 11 during the installation of the first-floor housing unit 11 to the second-floor housing unit 11 Can be sufficiently absorbed.

In the above embodiment, the house unit 11 is covered with the vinyl sheet 12 at the factory, but the vinyl sheet 12 may be covered at the construction site after being transported to the house unit 11 at the construction site.

In the above embodiment, the two-story house unit 11 has been described as an example. However, three or more stories may be used. In this case, for example, the two-story house unit 11 is installed before the three-story house unit 11 is installed. A water absorbing material 17 is laid on the upper surface of the vinyl sheet 11.

In the above embodiment, the water absorbing material 17 is laid only on the upper surface of the vinyl sheet 12 of the housing unit 11 on the first floor.
House unit 11 on the top floor like house unit 11 on the second floor
May be laid on the upper surface of the vinyl sheet 12. Accordingly, it is possible to prevent rainwater from dropping onto the housing unit 11 when the vinyl sheet 12 is torn and removed with a cutter or the like after the assembly operation of the housing unit 11 is completed.

Furthermore, in the above embodiment, the vinyl sheet 12 was used as the waterproof sheet, but any transparent synthetic resin sheet such as a polyethylene sheet may be used as long as the sheet is transparent and has waterproofness. Can be used with

[Effects of the Invention] According to the present invention, it is possible to easily remove rainwater accumulated on the upper surface of the waterproof sheet covered by the housing unit,
Therefore, the housing unit can be easily and quickly assembled.
