Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a method of constructing a unit house using a prefabricated unit in a factory, and particularly to a unit in which upper and lower two layers are formed as one body. The present invention relates to a method of constructing an upper and lower two-layer unit house.

[Prior Art] In recent years, in order to shorten the construction period and save labor on site, unit housings are becoming popular.

This unit house is composed of a group of living rooms, and is constructed by assembling various box-shaped living room units that have been standardized in advance on a foundation in the field construction.

Conventionally, in this unit house, most of the houses to be built are configured by the living room unit.

At the joint between the unit on the first floor and the unit on the second floor in this unit house, a groove is formed above the ceiling of the unit on the first floor forming a box and below the floor of the unit on the second floor. Placing shaped steel to make a structure,
The channel steels are joined together by bolting.

In addition, some units have, for example, facilities such as bathtubs that require pipes installed in advance in a factory.

[Problems to be Solved by the Invention] By the way, since the unit is transferred from a factory by a truck or the like, the size is inevitably limited. Therefore, the floor plan of a unit house in which the living room is made up of units is also restricted.

And since the unit has sufficient strength even in the state of only the unit before being assembled as a house, when the adjacent units of the unit house receive stress, the stress is dispersed and each unit is As a result, the unit housing as a whole has more than necessary and sufficient strength, which is uneconomical in terms of the amount of building materials used.

In addition, there is a drawback that it takes time and effort to join the unit on the first floor and the unit on the second floor on site.

When piping in a unit house, the piping of the unit itself has already been done in the factory.Therefore, at the site, the work of connecting the pipes between the units, especially the piping on the second floor, I was doing work to connect to, but this work was also troublesome.

Therefore, the work of joining these units and the work of connecting the pipes have been obstacles to the labor saving of the on-site work.

The present invention has been made in view of the above circumstances,
By eliminating the need to join the unit on the first floor and the unit on the second floor and the connection between the pipe on the first floor and the pipe on the second floor, labor can be saved on site, reducing the restrictions on the floor plan of the unit housing and reducing building materials. It is an object of the present invention to provide a method of constructing an upper and lower two-layer unit house that can be constructed.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the first invention, a unit in which a floor, a wall, and a ceiling are fixed to a frame is manufactured at a factory, and the unit is constructed at a construction site. A method of constructing a unit house by assembling a house by using the above method to form the unit by combining the upper and lower two layers in a factory, and arranging a plurality of units at intervals at a construction site. It is characterized by constructing a house by providing floor panels and wall panels between units.

A second aspect of the present invention is a method for constructing a unit house, in which a unit is manufactured by fixing a floor, a wall, and a ceiling to a frame in a factory and the house is assembled at the construction site using the unit. At the construction site, pillars are placed at intervals with respect to the unit, and floor panels and wall panels are provided between the pillars and the pillars. It is characterized by building a house.

[Operation] According to the above configuration, the upper and lower two layers are integrally formed to form a unit, so that it is possible to construct a unit housing without joining the unit on the first floor and the unit on the second floor at a construction site.

And the piping over the upper floor and the lower floor can also be done in the factory.

In addition, most of the unit houses are not configured by the units, but the units or the units and the pillars are arranged at intervals, and the floor panel is hung between them to construct the house. Since the part does not have to be restricted by the layout, the layout can be decided freely.

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

In the construction method of the upper and lower two-layer unit housing of the first embodiment, first, a frame 1a of the upper and lower two-layer unit 1 shown in FIG. 1 is manufactured in a factory. When manufacturing this frame 1a, the pillars 2 and the beams 3 of the laminated wood are used which are made by adhering small square timbers with the fiber direction aligned with the longitudinal direction and stacking them with an adhesive.
Then, the four columns 2 are arranged in parallel to the corner positions of the frame 1a, and the four columns 2 are respectively connected to the upper and lower ends and the central portion of the four columns 2 to connect the four columns 2 to each other. 3 is assembled in a rectangular frame shape to form a substantially box-like shape that is long in the vertical direction.

Needless to say, the pillars 2 and the beams 3 may be steel-made pillars 2 and beams 3 instead of the laminated wood.

Further, since the size of the unit 1 is limited in transportation from the factory to the site, the size of the unit 1 as a whole fits in the bed of the truck when the units 1 are stacked side by side, and the road traveling is hindered. It is set to a height that will not bring it.

Next, equipment such as a bathtub is attached to the frame 1a. At this time, since the skeleton 1a is configured to be long in the up-down direction, the skeleton 1a is laid down sideways and the installation work of the equipment is performed in a stable state. Therefore, it is not necessary to dig under the floor for the piping work under the floor on the first floor or the second floor, and the piping work can be performed in a comfortable posture.

In addition, the piping work in the factory makes it easy to connect piping between the first floor and the second floor.

Next, a panelized floor, wall, ceiling or the like is installed in a portion that does not interfere with the construction work of the unit 1 on site.

Then, the completed four units 1 are transferred to the construction site by a truck.

As shown in FIG. 2, at a construction site, four units 1 are installed on a prefabricated foundation 4 so as to be arranged at four corners of a house.

Then, as shown in FIG. 3, these four units 1
A floor panel 5a is laid between the lower part and the central part of the floor to install the floors 5 on the first and second floors.

At this time, a beam may be spanned between the units 1 and then the floor 5 may be formed thereon.

Next, the wall panel and roof panel are installed and the exterior is installed.
Then, the interior is completed and a two-story unit house (not shown) is completed.

At this time, the parts other than the unit 1 do not have to be restricted by the size of the unit due to the transfer using the truck, so that the layout can be freely decided.

According to the method for constructing the upper and lower two-layer unit housing of the first embodiment, the unit 1 is integrated into the upper and lower two layers, so that it is necessary to join the unit 1 on the first floor and the unit 1 on the second floor in the field. Disappear.

In addition, work such as plumbing work that spans the upper and lower two levels can also be performed at the factory.

Therefore, the work of joining the upper and lower units 1 and the work of connecting the upper and lower pipes do not have to be performed on site, so that the work on the construction site of the unit house can be saved.

In addition, the vertically upper and lower two-layer unit 1, which is long in the vertical direction, can be worked in a stable state when the equipment is installed by laying it down sideways. The work to be performed can be performed in a comfortable posture, and the work efficiency can be improved.

Moreover, since most of the houses are not configured by the units 1 but only the units 1 are arranged at the four corners, like the conventional unit houses, the units 1 are adjacent to each other, such as the pillars 2, the beams 3 and the walls. Is never doubled,
Building materials can be reduced. Therefore, the cost of the unit housing can be reduced.

Furthermore, the unit 1 is arranged at the four corners, and the floor panel 5a is hung between them to construct a unit house. Therefore, for the part where the floor panel 5a other than the unit 1 is laid, the living room is transported by a truck. Because it is not restricted by, you can freely decide the floor plan.

The method of constructing the upper and lower two-layer unit housing of the embodiment of FIG. 2 shown in FIG. 4 is to arrange the unit 1 in the center and the pillars 10 on the foundations 11 at the four corners. The floor panel 5a is bridged over the above to install a wall panel to construct a house, and the description of the same components as those of the first embodiment will be omitted.

The construction method of the upper and lower two-layer unit house of the second embodiment is such that the floor panel 5a is laid between the units 1 in the first embodiment, whereas the floor panel is arranged between the unit 1 and the pillar 10. The configuration is almost the same, except that 5a is used.

When the floor panel 5a is bridged, a beam may be bridged between the pillar 10 and the pillar 10 or between the pillar 10 and the unit 1, and then the floor 3 may be formed in a beam shape.

The construction method of the upper and lower two-layer unit housing of the second embodiment has the same effect as that of the first embodiment, and since only one unit 1 is used, the layout is less restricted. , You can decide the layout more freely.

When manufacturing the unit 1, the unit 1 may be manufactured by directly combining the wall panel, the floor panel, the ceiling panel, etc. without forming the frame with the laminated wood or the steel frame. In addition to arranging the unit 1 at the four corners or arranging the unit 1 at the center and arranging the pillars 10 at the four corners, a plurality of units 1 or a plurality of units 1 and pillars 10 are arranged.
Needless to say, it is possible to construct a unit house by installing a floor panel 5a between the floor panel and the floor panel 5a.

In addition, the layout of the unit housing as a whole is almost eliminated, but the unit 1 itself is transported to the construction site by a truck, so that the size is also limited. However, the unit 1 is used only in a part of the house, and is a space suitable for installing various facilities such as stairs, elevators, bathrooms and toilets.

[Effects of the Invention] As described above in detail, according to the upper and lower two-layer unit housing of the present invention, by combining the units in the upper and lower two layers, the unit of the first floor and the unit of the second floor are constructed at the construction site. No need to join.

Further, it is also possible to perform the work such as the plumbing work which is continuously performed in the upper and lower two layers in the factory.

Therefore, the work of joining the upper and lower units and the work of connecting the upper and lower pipes do not have to be performed on-site, so that the work on the construction site of the unit house can be saved.

Also, for vertically long upper and lower two-tier units, it is better to lay them down to perform equipment installation work in a stable state, so when manufacturing units in a factory, Work under the floor such as piping work can be performed in a comfortable posture, and work efficiency can be improved.

In addition, by installing units between the units or the units and pillars at a distance from each other on the construction site, spanning floor panels between these units or between the units and pillars, and installing wall panels to build a house, Since there is no part where the pillars, beams, walls, etc. are doubled in the adjacent part of the unit unlike when most of the house is composed of units,
Building materials can be reduced.

Therefore, the cost of the unit housing can be reduced.

Furthermore, because floor panels are built between units or between units and pillars to build a unit house, the living room is restricted by trucks for parts where floor panels other than units are built. You can freely decide the floor plan.
