Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a floor structure of a building.

(Prior Art) Duct space for piping and wiring in conventional buildings is
As shown in FIG. 6, a ceiling (b) on the lower floor is installed below the floor slab (a) with a predetermined space, and is formed between the floor slab (a) and the ceiling (b). The space (c) was used.

(Problems to be Solved by the Invention) According to the conventional structure, the wiring and piping on the floor slab are erected through the floor slab (a) as shown by the arrow (d), and therefore the pattern is changed. It was difficult to change the position and maintain it.

Further, as shown by the arrow (e), the blowing and suction of air for air conditioning is limited to below the ceiling (b) surface, which makes it difficult to adopt the laminar air conditioning method described later. .

(Means for Solving Problems) The present invention has been proposed to solve such problems, and a floor slab is formed between adjacent beams at a right angle to each beam between adjacent floor slabs adjacent to each other. And a groove-shaped member whose upper surface is opened over the entire surface or partially opened is interposed in the gap so as to form a gap extending in the direction, and the groove-shaped member is adjacent to the floor slabs adjacent to each other. It relates to a floor structure of a building characterized by being tightly connected.

(Operation) As described above, in the floor structure according to the present invention, a groove-shaped member having an open upper surface is interposed in a gap orthogonal to each beam formed between floor slabs bridged between opposing beams, The same groove type member is tightly bonded to the floor slab adjacent to the same member, and the same member forms a groove groove extending in the direction perpendicular to each beam on the floor surface. It is used as a space and an air-conditioning space for blowing air above the floor and inhaling air from above the floor, and the space formed between the groove-shaped members adjacent to each other in the direction parallel to the beam It is used for air-conditioning space such as air blowout and air intake from below the floor, and wiring and piping on a specific floor can be freely taken out from the ceiling and floor of the specific floor.
Further, the conditioned air can be blown out and sucked in not only from the ceiling surface but also from the floor surface.

(Embodiment) The present invention will be described below with reference to the illustrated embodiment.

Opposing girders (1), as shown in FIGS. 1 and 2.
Precast concrete floor slab having a predetermined width between (1), or between girder and beam, or beam. (2)
Between the adjacent slabs (2) on the same floor, each of the girders (1)
A groove-shaped member (pre-concrete concrete having a gap t extending in a direction perpendicular to the direction (1)) and having an upper end open in each gap, or a fire-resistant other material ( 3) is arranged so as to project below the floor slab (1), and both side pieces of the groove-shaped member (3) are embedded in the floor slab (2) facing the groove-shaped member (3) by embedding bolts (4). Tighten up.

In the figure, (5) is a lid provided on the upper end opening surface of the groove-shaped member (3), and (6) is a ceiling.

Since the illustrated embodiment is configured as described above, the space (A) in the groove-shaped member (3) has wiring above the floor, piping space and air blowing above the floor, and air from above the floor. The space (B) between adjacent groove-shaped members (3) and (3) is used for air-conditioning space such as inhalation.
It is used as a piping space and as an air-conditioning space for blowing air below the floor and inhaling air from below the floor.

For this reason, the wiring and piping of the specific floor (R) can be taken out freely from the ceiling and floor of that floor, and the work of changing the positions of the wiring and piping and the maintenance work involved in the pattern change can be greatly reduced.

Also, air can be blown out and sucked in from the floor, so by blowing out air from the ceiling and sucking out from the floor,
A so-called laminar flow type air-conditioning method that maintains a good air-conditioning condition in the room is easily performed.

FIG. 4 shows another embodiment of the present invention, in which the floor slab is placed on the floor slab (2a) made of precast concrete that is bridged between the beams and the post slab is placed on the same slab (2a). Composed of concrete (2b).

In the figure, the same parts as those in the above embodiment are designated by the same reference numerals.

FIG. 5 shows still another embodiment of the present invention, wherein the floor slab is composed of a slab (2c) with cast-in-place ribs, and the groove type member (3) has a groove type iron plate (3a) with a fireproof coating (3b). It is composed of layers.

(Effects of the Invention) In the present invention, a groove-shaped member having an open upper surface is interposed in a gap formed between floor slabs bridged between opposing beams and extending in a direction perpendicular to the beams, so that the groove-shaped member is formed. The space inside the member is used as a space for wiring above the floor, a space for piping, and an air conditioning space for blowing air above the floor, sucking air from above the floor, and the space between adjacent groove-shaped members. Can be used as an air-conditioning space for blowing air to the lower floor and inhaling air from the lower floor.

For this reason, wiring and piping on each floor can be taken out freely from the ceiling and floor of that floor, which greatly reduces the work of changing the wiring and piping positions associated with maintenance and interior remodeling. Since the air can be sucked in from the floor as well, it is possible to use a so-called laminar flow type air conditioning method in which air is blown out from the ceiling surface and is inhaled from the floor surface so that the air-conditioning state in the room is kept good.
