Description

[Detailed Description of the Invention] The present invention is waterproof and can be applied to roofs, balconies, eaves, floors, underground walls, water tanks, etc. of buildings! This is about construction.

1. Waterproofing each part of a Yokita building or a water tank is often done by pasting a waterproof sheet on the surface of the concrete frame. In many cases, an adhesive was applied to the waterproof sheet and the waterproof sheet was then adhered to the surface of the building structure.

Especially when waterproofing is done by pasting a tarpaulin sheet,
Corner edge formed by two adjacent surfaces of Concrete 1 to Concrete construction intersecting each other at almost right angles (Also corner formed by three adjacent surfaces intersecting each other at almost right angles) A corner edge with a circular cross section formed by passing a four-way member such as a pipe through a concrete sentry body and two faces intersecting each other at approximately right angles. It is difficult to watertightly cover the corner edges or corner parts of a cross-sectional square shape with a deck-like sheet, and conventionally, in the case of a rubber-based waterproof sheet, The sheet pieces 01 with cuts 02 as shown in FIG. Furthermore, by covering the vicinity of the corner point 04 and pasting an unvulcanized or vulcanized waterproof piece (additional tension piece) 05 formed in a similar three-dimensional shape, The gaps that tend to occur are sealed watertight.

In addition, in the case of vinyl chloride waterproof sheet], as shown in FIG. A three-dimensional waterproof piece 08 formed as shown in the figure is attached to a corner point 09.
There were many things stuck around it.

Therefore, when extending the waterproof piece 05.08 to the corner, the heat blown from the hot air generator is generated between the sheet piece 01.06 and the waterproof piece 05.08 placed along the sheet piece 01.06. Heat fusion bonding is generally employed in which the contact surfaces of the two parts are melted and softened by blowing water into them, and then pressure is applied with a roll or the like from the waterproof part 05.08 side to melt the two parts together.

However, in the above conventional waterproofing construction, the waterproofing part 05
．． 08 is molded in the same shape as the corner part, and when the waterproof part 05.08 is applied to the corner part, the waterproof part 0
5.08 is in close contact with the corner sheet piece 01.0G, so it is difficult to insert the hot air generator nozzle between the two, and the hot air does not reach the protrusion, that is, near the corner point. The welding in this area sometimes deteriorated, resulting in poor watertightness.

Also, when the waterproof piece 05.08 is applied to the corner, the periphery of the waterproof piece 05.08 will be stuck at the corner with wrinkles etc. formed on the piece 01.0G. If it is completely heat fused, the S and a of this part will be bad, which will further impair the watertight effect of the waterproof sheet, and if these corners or corners are not uniform in shape. There were many problems, and the work was often performed in difficult locations, making it difficult to perform the work.

2. For this reason, the present invention relates to a new waterproof structure that overcomes these difficulties, and includes corner edges or corners formed by the surfaces of concrete bodies touching each other. Alternatively, in a structure having a corner edge or a corner formed by passing a penetrating member such as a pipe through a concrete frame, a waterproof sheet extended and attached to the surface of the concrete frame; By providing a time-hardening filler that is closely filled in the mutually joining corner or corner of the sheet or the mutually joining corner or corner of the waterproof sheet and the penetrating member, concrete Penetration of a pipe, etc. into a corner edge formed by two adjacent faces of a concrete frame or a corner formed by two adjacent faces intersecting each other at a substantially right angle, or a concrete frame. Part is V\through-C
Places where work is difficult, such as corners with a circular cross section formed by two adjacent surfaces intersecting each other at almost right angles, or corners with a rectangular cross section formed by three adjacent surfaces intersecting each other at approximately right angles. A corner or corner installed in the corner can be sufficiently surrounded by a time-hardening filler that is closely filled into the corner or corner, and the corner or corner Sufficient watertightness can be ensured.
