JPH06322908A - Waterproof structure of top face of slab of roof floor and the like - Google Patents

Abstract

PURPOSE:To install a projection line while clamping a waterproof sheet. CONSTITUTION:Projection line materials B are mounted on the top face of a waterproof sheet 2 on the slab A of a roof floor, etc., at required intervals. The projection line materials B consist of hold-down members 10 clamped to the slab A by screws 12 penetrated into the waterproof sheet 2 through sealing materials 11 and cover members 20 fitted into the hold-down members 10 and having line length. Flap pieces 21 in the overall length of both side edges of the cover members 20 are bonded with the waterproof sheet 2. The waterproof sheet 2 is pushed by the hold-down members 10, and the hold-down members 10 are clamped to the slab A, thus fixing the waterproof sheet 2 to the slab A by the hold-down members 10. Screw holes are sealed with the sealing materials 11, thus deteriorating no waterproof effect. The hold-down members 10 and the screws 12 are concealed and waterproof structure is favoured in a design by fitting the cover materials 20 to the hold-down members 10, and the infiltration of rainwater into the projection line materials B is prevented by the bonding of the flat pieces 21.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure in which a ridge line material is provided on the waterproof surface of a slab such as a rooftop to improve the design effect.

[0002]

[Technical background] The upper surface of a slab such as a rooftop is exposed to rainwater and therefore needs to be waterproofed. For example, a waterproof sheet such as vinyl chloride is laid on the entire upper surface. However, if the waterproof sheet is simply laid, its upper surface is a flat surface without any unevenness, which is inferior in design, and some improvements have been desired in order to improve the sense of value in recent years.

[0003]

As a measure for improving the above-mentioned design surface, provision of a ridge line material on the upper surface of the waterproof sheet is conceivable, and is currently being implemented.

[0004] However, the means is only to improve the design surface, and no improvement is seen in terms of strengthening the waterproof structure and workability. This is not interesting because it only increases the number of man-hours required for the ridge line material.

[0005]

In order to solve the above-mentioned problems, in the first invention, a waterproof sheet is laid on the upper surface of a slab such as a rooftop, and the upper surface of the waterproof sheet has a lateral direction,
Longitudinal or bidirectional ridge line members are provided at required intervals, and the ridge line members are a pressing member fastened to the slab with a screw penetrating the waterproof sheet, and a ridge line covering the pressing member. The cover member has a long length, and the cover member is formed with flap pieces bonded along the waterproof sheet along the entire length of both side lines in the length direction.

According to a second aspect of the present invention, in the first aspect of the present invention, the cover member has a pair of left and right downward locking pieces formed over the entire length at inner surface positions that are inward from both side edges by a required length. The both locking pieces are integrated with the pressing member by locking, and both side edges of the cover member are in contact with the upper surface of the waterproof sheet, and a sealing material is filled between the side edges and the locking pieces. It is configured to be.

[0007]

In the waterproof structure according to the present invention configured as described above, since the waterproof sheet is pressed by the pressing member of the ridge line material, and the pressing member is fastened to the slab,
The waterproof sheet is fixed to the slab by this pressing member.

Further, by covering the pressing member with a cover material, the pressing member and the screw are hidden, which is also preferable in terms of design. Furthermore, by adhering the flap pieces or filling the sealing material, rainwater is injected into the ridge line material. Invasion is prevented.

[0009]

EXAMPLE As shown in FIGS. 1 to 3, a vinyl chloride waterproof sheet 2 is laid on an upper surface of a slab A with an insulating sheet 1 made of expanded polyethylene interposed therebetween. The tarpaulin 2
Vertical ridge line members B are provided on the upper side at required intervals in the horizontal direction.

The ridge line material B is composed of a pressing member 10 made of hard vinyl chloride and a cover 20 thereof, and both are integrated by fitting. The holding member 10 has an H-shaped cross section at the center, the lower surface recess is filled with the sealing material 11, and the screw 12 is screwed into the upper recess,
Fasten to Slab A. At this time, screw holes may be formed in the pressing member 10 in advance. The fastening position (screw position) is appropriately set in consideration of the laid state of the waterproof sheet 2.

The cover member 20 covers the entire length of both side edges in the lengthwise direction of the chevron portion fitted to the pressing member 10, and the flap piece 2 is formed.
1 is a two-color extruded product in which the chevron portion is made of hard vinyl chloride or semi-hard vinyl chloride and the flap piece 2 is made of soft vinyl chloride. The flap piece 21 is adhered to the waterproof sheet 2 by a solvent (adhesive) a or heat fusion, and the flap piece 21 is made soft to facilitate the adhesion. This flap piece 21
The sealing material 11 is not always necessary because the water is stopped by adhesion of the sealing material 11.

The flap piece 21 may be rigid as long as it can be adhered with various adhesives while keeping the waterproof effect. Cover member 2
The 0 seam is covered with a cover 22 for adhesion, or a tape 22 of soft vinyl chloride or the like is attached. Also, the flap piece 2
The edge of No. 1 is sealed with a liquid sealing material 23.

FIG. 4 shows another embodiment. The cover member 20 of this embodiment is made of hard vinyl chloride and has a pair of left and right downward locking pieces 2 at the inner surface positions having a required length inward from both side edges.
4, 24 are formed over the entire length of the line, and both locking pieces 24 are locked to the pressing member 10 to be integrated. Both side edges of the cover member 20 are in contact with the upper surface of the waterproof sheet 2, and a sealing material 25 is filled between the side edge and the locking piece 24. The sealing material 25 prevents rainwater from entering the ridge line material B.

In the embodiment, the entire surface of the waterproof sheet 2 is slab A.
This is an example of so-called insulation lining that is not adhered to the (insulation sheet 1), but the whole surface gluing of the waterproof sheet 2 to the entire surface of the slab A, or the combined use of insulation lining and adhesive gluing (the waterproof sheet 2 is partially Needless to say, the present invention can be adopted even if they are bonded). In addition, the pressing member 10 is a cover member 20.
Does not have to extend over the entire length of. That is, it may be a required interval.

Further, when the waterproof sheet 2 is composed of a plurality of sheets, if the ridge line material B is placed on the joint and fastened, the waterproofing and fixing processing of the joint can be performed at the same time, and the work efficiency is improved. Can be improved.

The ridge line material B, the waterproof sheet 2, etc. may be made of various materials such as rubber, ethylene resin, chlorinated polyethylene, etc., in addition to vinyl chloride. Further, the facility of the ridge line material B may be not only in the vertical direction but also in the horizontal direction as in the embodiment, and may be in both directions (cross shape).

[0017]

As described above, according to the present invention, since the projecting line member is provided with fixing the waterproof sheet, the waterproof structure having a high design effect can be formed with good workability.
