Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to a precast concrete floor plate with integrated small beams (hereinafter referred to as a PC floor plate), which is suitable for use mainly in the core of equipment in apartment complexes. ).

(Conventional technology) Currently, in apartment complexes such as condominiums, the living areas are placed on the corridor side and balcony side due to the floor plan, so the equipment-related space tends to be concentrated in the central area as the equipment core. .

However, the core of the equipment requires space for exhaust-related ducts on the ceiling, and space for water supply and drainage piping on the floor.

On the other hand, recently, as a measure to prevent noise problems between the upper and lower floors of apartment complexes, efforts have been made to make the concrete floor as thick as possible to increase the sound insulation and rigidity to prevent the propagation of the vibration from the floor vibration table. Movement is increasing.

(Problem to be solved by the invention) However, in the conventional floor concrete structure,
As shown in Fig. 3, a concrete floor 2 is formed on the small beams 1, It is necessary to create a double floor by providing floor finishing material 4 on top of the
It is common practice to attach a ceiling finishing material 6 to prevent the ceiling from being exposed indoors, and as a result, it is difficult to secure the ceiling height.

Therefore, if an attempt is made to increase the thickness of the concrete slab as described above, the ceiling height will become even lower, making it difficult to achieve this goal.

(Means for Solving the Problems) The present invention has been proposed in order to solve the problems of the conventional art, and is designed to form a piping space in the upper part and a duct space in the lower part between a pair of small beams. In this manner, by using a small beam integrated PC floor plate with an H-shaped cross section that is integrally connected at the floor, piping can be arranged without having to create a double floor, and the increase in the thickness of the floor concrete can be easily rotated. It is characterized by the following.

(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of the present invention, and the small beam integrated PC floor plate IO according to the present embodiment has a cross-sectional path H.
By integrally connecting a pair of PC beams 11.11 with a PC floor 14 at an intermediate position in the height direction, a piping space 12 is provided above the PC floor 14, and
A duct space 13 is formed in the lower part.

Therefore, in constructing the small beam integrated PC floor board 10 according to the present embodiment, as shown in FIG. The portion is tightly connected to a door boundary wall, a beam, etc. (not shown) by an appropriate means.

Next, in the case of this embodiment, the end of the PC floorboard 15 of the living room part, which was precast in the same way, is suspended on the small beam 11, and the PC
Leaving a space for installing piping on the upper surface of the floorboard 10, poured concrete is placed and hardened so that it is flush with the top of the PC floorboard 15 for the living room, and then hardens the PC floorboard 10 and the PC floorboards 15 for the living room on both sides. 15.

In the piping space 12, equipment piping 16 for water supply, drainage, gas, etc. is arranged, a joist 17 is installed on the upper surface, and a floor finishing material 18 is attached.

Further, various ducts 19 may be installed in the duct space 13, and a ceiling material 20 may be arranged in alignment with the lower end of the small beam 11.

In this way, in accordance with the recent housing complexes in which equipment cores are formed, in this embodiment, the equipment piping 16 and the duct 19 are separated into the piping space 12 and the duct space, respectively, by using the small beam integrated PC floor plate lO. 13, there is no need for all floors to be double floors as in the past.

It is important to ensure that the ceiling height is high enough, including in the living room.

Therefore, it is possible to fully meet the demand for increasing the floor thickness.

Further, since the duct 19 is not exposed in the ceiling part, there is no need to separately provide a decorative beam to hide it as in the past.

In addition, the dimensions between the PC beams 11 and 11, the beam width, etc. can be set arbitrarily according to the piping to be stored, the number of ducts, etc., within the scope of the gist of [Unissued I]. Needless to say, there are various modifications and rotations.

(Effects of the Invention) The present invention is configured as described above, and by devising the PC floorboard of the equipment core in relation to the small beams, equipment piping and ducts can be stored on the 1st floor without wasting space. This is extremely useful as it allows you to secure ceiling height and increase floor thickness.
