Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a foundation drainage structure for houses, etc.

(Prior Art and Problems) As a conventional method for draining foundations of houses, etc., a method of applying mortar from foundation to foundation is generally used.

However, this method has problems with workability because it takes time and effort to apply and dry the mortar and is affected by the weather.

Furthermore, a method using a drain plate is known, such as in Japanese Utility Model Application No. 168013/1983, but there is room for improvement in waterproofing the joints of the drain plate and in the method of fixing the drain plate.

(Object of the Invention) The object of the present invention is to solve the above-mentioned conventional problems and provide a foundation drainage structure with good workability.

(Embodiments of the Invention) The foundation drainage structure of the present invention will be described below according to embodiments shown in the drawings.

FIGS. 1 and 2 show a foundation drainage structure according to the present invention, and the foundation drainage structure has a foundation 2 such as a steel material (the one shown is a channel steel) installed on a foundation 1.

The base 2 has a drain plate 1 from its top surface to the front.
covered by 0.

The drain plate 10 is formed by bending a steel plate or the like as shown in FIG.

That is, the draining plate 10 has a top surface portion 12 and a front surface portion 13 that are continuous with each other in a substantially L-shape.

The front portion 13 is provided with a recess 14 extending in the transverse direction, and an adhesive 17 such as adhesive tape is adhered to the back surface of the recess 14.

Further, a hanging portion 15 that bends forward and hangs down is continuous to the lower edge of the front portion 13.

On the other hand, a rising portion 11 that rises upward continues at the rear edge of the top surface portion 12 .

The draining board 10 described above is attached to the foundation 2 with its top surface 12 and front surface 13 covering the foundation 2, and with its hanging portion 15 covering the upper part of the foundation 1.

That is, as shown in FIG. 1, the draining plate 10 is attached to the front surface of the base 2 in its recess 14 using the adhesive 17.

Next, the pillar 3 is installed on the base 2 through the drain plate 10 at the joint of the drain plate 10, and is fixed to the base 2 integrally with the drain plate 10.

In other words, the hole 4 in the bottom plate 4 fixed to the bottom of the column 3
The column 3 is fixed to the base 2 by a bolt 27 inserted through a hole (not shown) in the drain plate 10 and a hole 2a (see FIG. 4) in the base 2.

Next, a wall panel 7 is mounted between adjacent pillars 3 and supported by them on the top surface 12 of the draining board 10.

Next, since the draining plate 10 has a fixed length, it has a seam, and an example of a method of waterproofing the seam is shown in FIGS. 4 and 5.

That is, a drain plate joint 20 is provided, and the drain plate joint 20 has substantially the same cross-sectional shape as the drain plate 10.

That is, the rising part 21, the top part 22, the front part 2
3. It has a recessed part 24 and a hanging part 25.

A waterproof means such as an adhesive or a sealant is attached to the surface of the draining plate joint 20, and the adhesive,
A waterproof means such as a sealant is overlapped and bonded to the back surface of the end portion of the draining plate 10 in a close state.

In addition, in the illustrated embodiment, the drain plate joint 2
A bent piece 26 is provided on the upper edge of 0 and a bent piece 16 is provided on the lower edge of the drain plate 10, and by bending these pieces as shown in FIG. 5, the drain plate joint 20 and the drain plate 10 are firmly joined. made possible.

Furthermore, in order to waterproof the bolt 27 portion, EPDM is installed between the bottom plate 4 of the column 3 and the drainage plate 10 as shown in Fig. 5.
It is preferable to use a seal 8 of a resilient material such as foam.

Further, in order to make the space between the wall panel 7 and the drain plate 10 waterproof, it is desirable to interpose a seal 9 along the bottom surface of the wall panel 7 as shown in FIG.

(Effects of the Invention) Examples of the foundation drainage structure of the present invention are as follows, and the effects thereof are listed below.

(1) The foundation drainage structure of the present invention has the structure described in the claims, and in particular, there is no need to use mortar or the like to cover the foundation with the drainage board, and as a result, workability is extremely good.

(2) The foundation drainage structure of the present invention has the same configuration as above,
In particular, since the draining board is attached to the base with adhesive, the installation work is extremely easy.

(3) The foundation drainage structure of the present invention has the same configuration as above,
In particular, the joints of the drain plates are waterproofed by the joints of the drain plates to which a waterproofing means is attached, so that no water leaks from the joints.

(4) The foundation drainage structure of the present invention has the same configuration as above,
In particular, the draining board is fixed to the foundation integrally with the pillar, which not only reduces the time and effort of fixing work, but also ensures secure fixation.
