Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure in which water supply / drainage pipes can be easily installed under the second floor.

[0002]

2. Description of the Related Art When installing a bath / kitchen on the second floor of a general house, it is necessary to provide piping for water supply / drainage to the second floor. Conventionally, such pipes are buried along the outer wall or in the outer wall, or between the first floor ceiling and the second floor below.

[0003]

Conventionally, when piping is provided between the first-floor ceiling and the second-floor underfloor, since there is a base of the first-floor ceiling, for example, a hanging tree or a hanging crate receiver, the position of the underlying material should not be changed. Since the piping is avoided, it is not possible to construct the piping freely, and this piping requires labor and material costs are high.

According to the present invention, another beam is partially fixed to the lower part of the lattice beam on the second floor to form a step with the normal second floor.
The purpose is to use the space to easily connect the water supply and drainage pipes.

[0005]

The present invention has been made to achieve the above-mentioned object, and another lattice beam is arranged in parallel with the inside of the lattice beam at the position of the outer wall panel, and the lattice beam opposite to this lattice beam is arranged. A girder is erected between the lower parts of the beam, and a beam is arranged along the floor panel and the side surface of the lattice beam on the girder to form a piping space, and the upper surface of this piping space is covered with a floor material. What is done is summarized.

[0006]

[Operation] A gable is installed between parallel lattice beams and the space surrounded by the grate beam and gable is used as a piping space.
The floor material laid on the floor panel on the lattice beam covers the upper surface of the piping space. As a result, a space under the second floor without a hanging tree or a hanging tree can be secured, so that piping can be performed easily, labor saving in construction and wasteless piping arrangement can be performed.

[0007]

The floor structure of the present invention will be described below with reference to the illustrated embodiments. In the drawing, reference numeral 1 denotes an outer wall panel on the second floor side, and a lattice beam 2 is arranged at a lower portion of the outer wall panel 1. The lattice beam 2 is arranged parallel to the lattice beam 2 at the outer wall panel position with a required space inside thereof. The beam 3 is arranged.

A large pull 4 is installed between the lattice beams 2 and 3 which are installed in parallel inside and outside and at a lower position of the lattice beam, and a desired floor panel such as an NPC floor is provided on the inside lattice beam 3. Etc. 5 are laid.

The space between the lattice beams 2 and 3 facing inside and outside and the space 4 is defined as a piping space for water supply and drainage. For this reason, a floor panel 6 having the same structure as or a different structure from the floor panel 5 is arranged on the draft 4 to close the bottom of the piping space, and the upper surface of the floor panel 6 is also provided inside the lattice beams 2 and 3. Beams 7 and 8 are provided so as to be in contact with each other. At this time, the upper end surfaces of the beams 7 and 8 are made equal to the top surface of the floor panel 5 on the lattice beam 3.

A floor material 9 such as a particle board laid on the floor panel 5 is arranged so as to bridge the upper portions of the beams 7 and 8 to form a second-floor floor surface, and the beams 7 and 8, The floor panel 6 and the floor material 9 completely surround the piping space.

Therefore, a water supply pipe / drainage pipe or other pipe is piped in this pipe space. This pipe is surrounded by the beams 7 and 8 and the floor panel 6 on three sides and is required when the upper surface is open. After the work, the floor material 9 covers the upper opening surface.

Further, the embodiment shown in FIGS. 2 and 3 is different from the embodiment shown in FIG. 1 in the method of fixing the beams 7 and 8 constituting the piping space. In the embodiment shown in FIG. 1, the beams 7 and 8 are formed by inserting bolts into the lattice beams 2 and 3, respectively, and attaching a nut to the beams so that the two beams are integrated, whereas the beams 7 and 8 are provided in the embodiment shown in FIG. Support metal fittings for hooking on upper chords of lattice beams 2 and 3
0 is projected and fixed to the lattice beam through the support fitting 10.

Also in this embodiment, the structure of the lattice beams 2, 3, the hauling 4, the floor panels 5, 6 and the floor material 9 is the same as that shown in FIG. And the support fitting 10
May be fixed to the beams 7 and 8, but as shown in FIG. 3, it is tiltably supported via a hinge, and when it is hooked to the lattice beams 2 and 3, the support metal fitting 10 is swung, and then When the support fitting is returned to its original state, the beams 7 and 8 are locked at predetermined positions inside the lattice beams 2 and 3.

Further, in the embodiment shown in FIGS. 4 and 5, the beams 7 and 8 are used.
The beams 7 and 8 arranged inside the opposing lattice beams 2 and 3 are different from each other in the attachment, and are attached to the runners 11 directly fixed to the Daihiki at both ends of the floor panel 6 on the Daihiki 4. Supported.

The runner 11 has a U-shaped cross section and is fixedly installed on the large pulling opening so that the upper portion is opened. The width of the runner is set to be equal to or slightly larger than the width of the beams 7 and 8. The lower ends of 7 and 8 are fitted and locked in the runner. The installation position of the runner on the large pull is such that when the beam is fitted and locked in the runner, the beam is along the inner surface of the lattice beam.

Further, since the construction of the lattice beams 2, 3, the hauling 4, the floor panels 5, 6 and the like is the same as that of the embodiment of FIG. 1, its detailed description will be omitted.

The embodiment shown in FIGS. 6 and 7 is a lattice beam 2, 3
Beams 7 and 8 that are oppositely installed along the inside of the
It is connected by 12 and is made into one, and this is the floor panel 6 on the large pull.
It is installed above to form a piping space, and other configurations are similar to those of the embodiment of FIG. In this embodiment, the connecting rod 12 can be used to fix the pipe to be installed in the piping space.

[0018]

According to the floor structure of the present invention, another lattice beam is arranged in parallel with the inside of the lattice beam at the outer wall panel position, and a large pull is installed between the lower portions of the opposing lattice beams. Since the floor panel and the beams are arranged along the sides of the lattice beam to form the piping space and the upper surface of the piping space is covered with the floor material, the piping work is easy and wasteless even in a narrow space under the second floor. It has the advantage of being efficient.
