DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproofing technique for anchor bolts for fixing a double floor.

[0002]

2. Description of the Related Art In recent years, a so-called double floor having a double floor has become widespread for the purpose of efficiently and functionally storing wiring, piping, and the like. Because a double-floor base has a double floor, it is not possible to completely waterproof the finished floor because of the nature of the double-floor. Conventionally, as a method of providing a waterproof layer on a concrete slab, a method of asphalt waterproofing and then covering with a mortar, or a method of waterproofing a synthetic resin such as a vinyl chloride resin have been adopted. However, since the anchor bolts for fixing the legs supporting the double floor are driven into the base layer, holes are formed in the waterproof layer, and complete waterproofing cannot be achieved.

[0003]

An object of the present invention is to provide a waterproof structure for a double floor supporting leg by a simple construction method.

[0004]

The present invention relates to a base having a waterproof layer made of synthetic resin, rubber or asphalt on its surface, an anchor bolt driven into the waterproof layer and the base, and a double floor fixed by the anchor bolt. A supporting leg, and a skirt made of synthetic resin or rubber which is waterproofly adhered to the supporting leg, and a skirt of the skirt is waterproofed in a state where the skirt completely covers the anchor bolt. The present invention relates to a waterproof structure for a double-floor support leg, which is bonded to a layer.

There are no particular restrictions on the synthetic resin or rubber forming the waterproof layer or skirt, but a typical example is a vinyl chloride resin, and in addition, polyethylene, polypropylene, polyester, polyamide,
Natural rubber and SBR can be exemplified. Asphalts include straight asphalt, blown asphalt, modified asphalt, and the like.
When the material of the waterproof layer and the material of the skirt are the same material and have heat sealing properties, heat sealing can be used as a means for bonding the skirt of the skirt to the waterproof layer. The adhesion between the skirt hem and the waterproof layer is not limited to heat sealing, and various adhesives, waterproof putty, and the like can be used.

As means for waterproofing the double floor support leg and the skirt, there are a method of winding a tape, a method of hot-press sealing, and a method of closely bonding with an adhesive or putty. If the surface of the support leg is previously covered with the same material as the skirt, the adhesion can be more completely achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a double floor support leg 1 is fixed on a concrete slab 6 using an anchor bolt 2. The anchor bolt 2 penetrates the vinyl chloride resin layer (2 mm thick) as the waterproof layer 3 and is embedded and fixed in the slab 6. Then, a skirt 4 made of a 1 mm thick vinyl chloride resin sheet was perforated on the support leg 1, and a contact portion between the support leg 1 and the skirt was fixed by winding a commercially available electrical construction tape 7 from below to above. . The contact portion between the waterproof layer 3 and the skirt of the skirt was tightly sealed with a silicone resin sealant 5.

[0008]

According to the present invention, waterproofing of a double floor can be easily completed by employing the structure of the present invention.
