2. Description of the Related Art In a conventional housing system, when constructing a boundary wall, a partition wall or a floor of a dwelling unit, first,
In the case of a doorway wall, a formwork for assembling the doorway wall together with the pillars and beams when assembling the framework is assembled, and the structure concrete is poured into the formwork. There is a dry construction method for forming a wall or a frontal wall by a PC version or an ALC version that is factory processed as a special construction method. In addition, regarding the floor of the interior of the dwelling unit space such as the above-mentioned concrete concrete, there are construction methods such as a dry floor, a loose floor joist floor, and a straight floor.

FIG. 12 is a structural explanatory view showing a dry floor, in which 1 is a modular floor panel and 2 is a floor panel.
Is a floor level adjusting leg that supports the floor panel 1 at, for example, four points, and 3 is equipment piping laid in the space between the floor panel 1 and the body floor slab 4, which constitutes a dry floor. There is.

FIG. 13 is an explanatory view showing the construction of a rolled-out joist floor. In the figure, 1 is a floor panel, 3 is equipment piping,
Reference numeral 4 is a body floor slab, 5 is joist, and 6 is a floor level adjusting mechanism. The floor panel 1 and the base are separated from each other, and the joist 5 is rolled on the body floor slab 4 and the floor panel 1 is stretched thereon. It has been configured.

FIG. 14 is a perspective view showing a construction of a wall of a rolled-out joist floor. In the figure, 7 is a pillar, 7a is a furring strip receiver, 8 is a stud, 9 is a furring strip, and 10 is a siding board such as plywood veneer. Yes, these constitute the wall of the rolled-out joist floor.

Regarding the partition wall in the dwelling unit as described above,
In the dry floor construction method shown in FIG. 10, a combination of lightweight steel aggregate and fire-resistant boards, and in the expanded floor joist floors shown in FIGS. 11 and 12, struts 7, studs 8, furrows 9, plywood veneer 10, etc. It is composed of. On the other hand, as for the water supply and drainage pipes laid under the floor, the conveying path is formed by sewing the gaps between the respective constituent materials, and the floor heating piping is also constructed as a floor plate integrated or a sandwich between the exclusive material on the joists and the floor plate. .

The boundary wall in the conventional housing system construction method is formed on the cast concrete slab on the floor on the floor by the form material together with the pillars and beams on the floor, and the ceiling slab concrete (upper floor slab is used. ) Or concrete pouring method by pouring concrete, or a dry construction method in which PC plate or ALC plate etc. factory processed after pouring the floor slabs of the floor concerned and the upper floor by the above method are attached to the upper and lower slabs with fixed hardware. Composed.

Further, the interior partition / floor of the dwelling unit space made of such skeleton concrete, etc. is subjected to secondary processing on-site in accordance with the dimensions by mass-produced materials delivered by each interior builder, and the partition wall → ceiling → floor It is constructed in order. For example,
In the interior construction work in the dry floor system, the formwork material is disassembled after the training period after placing the concrete in concrete, and the smears of the partition walls, etc. → Installation of channels on the floor / underfloor (ceiling) slab → Light weight on the same channel section It is constructed by each interior contractor in the order of building the steel-frame partitioning material → lightweight ceiling base → ceiling finish board attachment → floor panel laying / land adjustment → wall finish attachment (or painting).

On the other hand, the facilities for water supply / drainage / ventilation / electricity are installed in accordance with the above-mentioned interior construction work by suspending the ventilation duct in the ceiling between the construction work of the lightweight steel partition wall and the interior work of the lightweight ceiling base, After completing wiring and equipment work in the ceiling, pipes for water supply / drainage, heating / cooling (or floor heating), etc. will be installed and connected to the ventilation gallery and lighting fixtures / wired when the ceiling finishing board is attached. From the point of completion of the introductory work of wall finishing, installation of sanitary equipment, connection pipes, etc. will be sequentially installed by workers of each facility.

[0010] The ceiling, underfloor, and walls of equipment such as pipes, ducts, and wiring of each equipment are reflected on the construction drawings, so that sanitation, air conditioning, and air conditioning are based on the interior finish drawings. Each electric equipment supplier will discuss with each other, apportion the limited route space, determine the rules for construction, and create a construction drawing.

In addition, due to the drainage system of gravity drainage around the water area, unevenness of the floor of the dwelling unit occurs depending on the underfloor equipment transportation space, which may cause the elderly to fall or the like.

[0012] In addition, in the case of floor heating pipes replacing the heating pipes, a specialist contractor is installed between the ceiling finishing board and the laying of floor panels in the same manner as each facility work.

[0013]

As described above, since the boundary wall formed by the conventional housing system construction is made of skeleton concrete, or PC / ALC plate, in skeleton concrete construction, the formwork and scatter are different. In addition to the need for training, it takes time and labor for the form carpenters and miscellaneous workers who have work experience and skills, and PC / ALC versions must be constructed by specialists instead of the form carpenters.

Further, as in the case of the boundary walls, the partition walls and floors in the interior construction work also take time and effort from a specialist. Furthermore, in the work flow of the interior partition wall, ceiling, and floor described above, the interior work and facility work for each part of the ceiling, floor, and wall, and the facility work such as water supply / drainage, air conditioning, and electricity are preceded / simultaneous. -Not only does the work of any job be divided due to the subsequent work, but the delay in the interior work affects the equipment work, resulting in a similar appearance in each equipment work.

In other words, due to such waiting work, mutually unreasonable, wasteful, and uneven work situations are generated, and as a result, humans are thrown in within the restricted time in order to recover the delay, so-called 3K of a construction company. (Kitsui Kitanai
I'm forced to do some hard work, which is one of these.

[0016] In addition, with respect to the boundary walls and the partition walls, it is not possible to change the responsiveness to the life stage and life cycle of the occupants. A large amount of renovation work is required to deal with this, and a great burden is imposed on realizing the needs of residents.

On the other hand, as for the equipment underfloor transportation route, which is concealed piping and wiring under the floor, the interior base materials such as walls and floors are avoided, and moreover, the narrow space is cross-piped and accommodated. Therefore, the red water generated due to leaks / clogging and aging of pipe materials is dealt with by repair work that causes the interior to be demolished. not to mention,
It was impossible to change the water stage in response to resident's life stage and life stage change without demolishing the interior.

The present invention has been made in order to solve the above-mentioned problems, and makes it possible to change the partition wall and the water area around the boundary wall, and the accompanying underfloor equipment transportation route.
