Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a floor structure used for a floor of an outer corridor exposed to the outside of a building.

[Conventional technology]

As is generally well known, the floor structure of the outer corridor exposed to the outside of the building consists of a flat floor plate member, and in particular, the floor plate used at one end of the floor structure includes rainwater falling on the floor. There is a drainage channel for discharging dirty water when cleaning and cleaning. As shown in FIG. 8, the drain groove 21 is provided near one edge of the upper surface of the floor plate 11 from one side to the other side, and the drain groove 21 has a uniform width and depth.
Then, the floor structure using this floor board 11 is laid in a state where the floor board 11 having the drainage groove 21 is directed to one end side of the floor structure, and the drainage groove 21 is continuously connected, and the other part of the floor structure. In the drain 21
It is formed by laying a floor plate that does not have. Then, the sewage on these floor plates flows into the drain groove 21 and is discharged to the outside.

[Problems to be solved by the invention]

However, in the above-mentioned conventional floor structure, the drain groove 21
There is a problem that if the amount of sewage flowing into the inside is small, it will not be reliably discharged. In addition, since sand and dust that are incidental to rainwater and sewage easily accumulate in the drainage ditch 21, there are problems that clogging occurs and the flow of sewage is obstructed.

[Means for solving problems]

This invention was made in view of the above circumstances, and the concrete means is to incline a concrete floor plate having a drainage groove near one edge so that the one edge side is lower than the other edge side. In a floor structure in which a plurality of floor structure materials are continuously laid on the floor structure material, an inclination of about 1% that goes down from one to the other is provided on the bottom surface of the drainage groove of the one floor plate, and A drainage hole is provided on the lowest bottom surface of the drainage channel, and the bottom surface of the drainage channel of the other floorboard adjacent to the one floorboard is provided with an inclination of about 1% that decreases from the other to one side, and It has a floor structure that is combined with the floor plate so that the lower drainage channels are continuous.

[Action]

According to the above floor structure, when rainwater or sewage falls on the one floorboard or the other floorboard, since these floorboards are inclined from the other edge toward the one edge, the rainwater and sewage will follow this inclination. Flows toward one edge and then flows down to the drainage channel. Further, in the above-mentioned one floor plate, since the drain groove is provided with an inclination that descends from one side to the other side, rainwater and the like that have flowed into the drain groove flow from one side to the other side along the drain groove. , It is discharged from the drain hole provided at the lowest bottom of the drainage ditch.

Also, rainwater, etc. that has flown into the drain of the other floor plate flows from the other side to the one side in the drain, but one side, which is the lower side of the drain of the other floor, is the drain of the one floor. Since it is continuous with the other side, which is the lower side of the groove, rainwater, etc. in the drain of the other floorboard will flow into the drain of the one floorboard and from the drainage holes provided in the drainage of the one floorboard. Is discharged. Here, the inclination angle of the drainage groove is set to about 1%, if the inclination angle of the drainage groove is smaller than 1%, the effect of guiding rainwater or sewage in a predetermined direction in the drainage groove is poor, and conversely This is because if the inclination angle of the groove is larger than 1%, the depth at the lowest bottom surface of the drain groove becomes excessively large, and it becomes easy to induce cracking of the floor plate. In addition, sand and dust that have flowed into the drain along with rainwater and dirty water are also discharged to the outside at the same time.

〔Example〕

An embodiment of this invention will be described with reference to FIGS. 1 to 7.

This embodiment relates to a floor structure B of an outer corridor A exposed to the outside of a building, and a floor board 1 (1a, 1b) is laid on one end side of the floor structure B. Each of the floor boards 1a and 1b is a cement extruded product, and is a rectangular plate-shaped member preferably having a size of about 1 to 2 meters and a width of about 50 centimeters.

A floorboard 1a corresponding to another floorboard in the claims is, as shown in FIGS. 1 and 2, a drainage groove provided on the upper surface of a flat plate-like member along the longitudinal direction near one edge. The depth of one side of 2 is made deep and the depth of the other side is made shallow, and the bottom surface is provided with a slope descending from the other side to the one side. The slope of the drain groove 2 is set to about 1% so that the drain groove 2 does not become excessively deep and the floor plate 1a is not cracked while having a sufficient drain function. Is preferred.

A floorboard 1b corresponding to one floorboard in the claims is, as shown in FIGS. 3 and 4, a drainage groove provided on the upper surface of a flat plate-shaped member along the longitudinal direction and close to one edge. 2 has a shallow depth on one side and a deep depth on the other side, and the wastewater flowing through the drainage groove 2 is externally attached to the lowest bottom surface of the drainage groove 2 provided with an inclination that decreases from one side to the other on the bottom surface. A drainage hole 3 is provided for discharging to.

An example of use of the floor structure B of this embodiment will be described with reference to the drawings.

The floor structure B of the outer corridor A using the floor boards 1 (1a, 1b) is
As shown in FIG. 5 to FIG. 7, a floor board D having no drainage groove 2 is laid on the building side on the floor structure material C erected at regular intervals, and the floor structure B is on the opposite side of the building. Has a structure in which a floor plate 1 (1a, 1b) having this drainage groove 2 is laid and connected and fixed to a floor structural material C.

As shown in FIG. 5, the laying procedure of the floor plate 1 (1a, 1b) is as follows. The drainage grooves 2 are laid on the floor structure material C in a state where the lower ones are continuous. In this case, the drainage hole 3 is the floor plate 1 (1a, 1b) 1
It will be arranged every other sheet, and two floor boards 1 (1a,
The wastewater E flowing from the drainage groove 2 of 1b) will be discharged. In addition, when hand rubbing F is required as in the outer corridor A provided on the second floor and above, the drainage groove 2 and the floor plate 1 (1a, 1b)
It is installed between one edge.

When the rainwater or the sewage E during cleaning flows into the floor structure B of the outer corridor A formed by laying the floorboards 1 (1a, 1b) in the above procedure, all the sewage E is in the drainage ditch 2. It flows into. Then, the sewage E that has flowed into the drainage groove 2 flows along the slope of the drainage groove 2 toward the lower side, flows into the drainage hole 3 provided in the floor plate 1b, and is discharged to the outside. . At this time, the sand and dust attached to the sewage E are discharged together with the sewage E whose flow is urged by the inclination. Further, even if the amount of the dirty water E is small, since the flow is urged by the inclination, it becomes possible to flow to the drain hole 3.

If the floor structure B of the outer corridor A composed of the floorboard D and the floorboard 1 (1a, 1b) is inclined from the building side in the opposite direction to the building in which the drainage groove 2 is located, the floor structure B of the outer corridor A Since all the water accumulated above flows down to the drainage channel 2, the water does not collect on the floor structure B of the outer corridor A.

[Effect of device]

As is clear from the above description, the floor structure of this invention is
A plurality of floor plates having drainage grooves near one edge are continuously laid on the floor structure material in a state where the one edge side is inclined so that the edge side is lower than the other edge side, and the bottom surface of the drainage groove of the one floor plate In addition to providing a slope of about 1% that descends from one to the other, the drainage hole is provided on the lowest bottom of the drainage groove of this one floor plate,
The bottom of the drainage channel of the other floorboard adjacent to the one floorboard is provided with an inclination of about 1% that decreases from the other to one, and the one floorboard and the other floorboard are connected to each other in a lower drainage channel. Therefore, the drainage from each drain of the one floor plate and the other floor plate is performed only by the drain holes of the one floor plate, compared to the case where the drain holes are provided in each floor plate. The number of drain holes can be halved. So, for example,
When connecting a drainage treatment tool such as a drainage pipe to each drainage hole, the number of connection points of the drainage treatment tool is also halved.

Here, the drainage groove of the other floor plate is provided with a slope descending from one to the other like the drainage groove of one floor plate, and the lowest bottom surface of the drainage groove of one floor plate is the most It is conceivable to provide a drain hole on the lowest bottom of another floor plate while continuing to the higher bottom, but in that case, the depth at the lowest bottom of the drainage groove of the other floor plate is the lowest bottom of one floor plate. It is about twice the depth at. Therefore, when the drainage grooves of one floorboard and the other floorboard are inclined in the same direction as each other, the depth of the drainage groove of the other floorboard becomes excessively large compared to the thickness of the floorboard, which is an extreme case. However, there is a possibility that problems such as cracking of the other floor plates may occur at the drainage channel. On the other hand, as in the present invention, when the drain holes of one floor plate and the other floor plate adjacent to it are made to have the inclination directions opposite to each other and the lower drain holes are connected continuously, the depth of the drain groove is increased. Does not become excessively large, and problems such as cracks in the floorboard are unlikely to occur.
