Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of constructing a ceiling/floor structure of a building.

[Conventional technology]

Conventionally, in the construction of a ceiling e-floor structure for a building, for example, as shown in FIG. After the upper floor slab 3 is integrally formed on the upper surface of the material 1 and the small beam material 2, the underfloor wiring duct 4 and other piping are arranged below the upper floor slab 3, and the ceiling is installed to cover the piping. A method is used for attaching the finishing material 5 to the upper floor slope 3 using ceiling hanging bolts 6, hangers 7, edge brackets 8, edges 9, and the like.

[Problem that the invention seeks to solve]

According to the above conventional construction method, there are various problems described below.

(υ Installation of pipes such as underfloor wiring ducts and ceiling materials such as ceiling finishing materials cannot be carried out until after the concrete of each beam material and upper floor slab has hardened.1.
The construction period is long.

(2) The installation of piping and ceiling materials requires work from the lower floor in an upward position using a stepladder, etc., which makes these tasks difficult and requires a great deal of time.

(!l) If the position of partition walls is changed after construction and heavy objects such as automatic doors are installed, the strength of the ceiling material is low, so it is necessary to reinforce the ceiling base material such as the veranda.

Similarly, if changes are made to the underfloor wiring ducts, etc. after construction, the changes will be difficult work inside the ceiling.
The problem mentioned in 2) arises.

[Means for solving problems]

In order to solve the above problems, the present invention provides air conditioning air supply holes,
Slabs with recessed lighting equipment and ceiling finishing materials are placed between the pillars with appropriate distance between them, and concrete is filled between the adjacent slabs to form horizontal through holes on the top surface of the slabs. After forming large beams and small beams of equal beam size and integrally with the slab material using reinforced concrete, their lower surfaces (
Ceiling finishing materials are installed, bundled materials lower than the beam height of the beams are erected on the top surface of the slab material and concrete, and floor board materials are removably laid on the bundled materials so as to match the top surface of the beams. be.

[For production]

By filling concrete between the slab materials and attaching ceiling finishing material to the underside of the concrete, the ceiling of the lower floor equipped with air conditioning ventilation holes is completed. In addition, the space partitioned by the beams of the large and small beams between the floor of the upper floor and the ceiling of the lower floor communicates with each other through horizontal through-holes, making it possible to freely remove the floorboards on the bundled materials. Due to the installation, the upper floor works together with the lower floor ceiling to form a double-floor free access floor with a high degree of freedom for underfloor wiring, etc.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a sectional view showing a ceiling Φ floor structure according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line ■-■ in FIG.

In the figure, a large number of slab members 10 made of precast concrete are placed between pillar members (not shown) at appropriate distances.

Note that the slab material 10 has a plurality of air conditioning air supply holes 11 vertically penetrated through it at predetermined positions, and the lower surface of the slab material 10 is equipped with a recessed lighting fixture 12 on the lower floor and a ceiling finishing material. 13 is installed in advance, and then, in order to form the ceiling slab of the lower floor together with the adjacent slab materials 10 K and these slab materials 1o, concrete 14 is filled, and on the upper surface of the slab materials 10, A large beam 17 and a small beam 18 having a plurality of horizontally extending through holes 15 and 16 that function as air conditioning ventilation holes or underfloor wiring insertion holes, etc., and having the same beam thickness are formed by integrating the slab material 1o with reinforced concrete. do.

After the concrete 14 between the slab materials 10 has hardened, a ceiling finishing material 19 is attached to the lower surface of the concrete 14, and in parallel with the installation of the ceiling material 19, the upper surfaces of the slab materials 1o and the concrete 14 are appropriately coated with beams 17 and 18. Low multiple bundle materials 2o
are erected, and a large number of rectangular floorboards 21 are removably laid on these bundles 20 in alignment with the upper surfaces of the beams 17 and 18.

〔Effect of the invention〕

As described above, according to the present invention, the following effects can be obtained compared to the conventional technology.

(1) Air conditioning air supply holes, recessed lighting equipment, and ceiling finishing material are pre-installed on the slab material, so there is no need to assemble the ceiling base material as in the past, and the hardening of the concrete between the slab materials is eliminated. By attaching ceiling finishing material to the underside of the building, the ceiling of the lower floor can be completed in a short period of time.

('2) Since piping work such as underfloor wiring is performed in a downward position, these works can be easily carried out in a short period of time and with high precision.

(3) Even if there is a change in the position of a partition wall after construction, or a corresponding change in piping such as underfloor wiring, work must be done in an upward position using a stepladder, etc., as in the past, by reinforcing the ceiling base material. etc., are not necessary in line 5 (this makes the change work easier and can be done in a short period of time.

Claims (1)

[Claims] Slabs equipped with air conditioning air supply holes, recessed lighting fixtures, and ceiling finishing materials are placed between pillars at appropriate distances, and concrete is filled between the adjacent slabs to cover the top surface of the slabs. After forming large beams and small beams with horizontal through-holes and equal beam parts integrally with a slab material using reinforced concrete, ceiling finishing material is attached to the lower surface of the beam, and the beam structure of the beam is attached to the upper surface of the slab material and concrete. A method of constructing a ceiling/floor structure in which a low bundle of materials is erected, and a floorboard material is removably laid on the bundle of materials so as to match the upper surface of a beam.
