JPH0742792B2 - Waterproofing method for the rising part from the flat roof floor - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a waterproofing method for a rising portion from a flat roof floor portion of a flat roof parapet or a rooftop rooftop.

[Conventional technology]

As shown in FIG. 5, the conventional waterproof structure for a flat roof is such that a waterproof layer 33a such as asphalt is formed on a floor concrete layer 32 of the flat roof 31, and a parapet (a rising wall) 34 is formed next to the waterproof layer 33a. Waterproof layer 33b on the inner surface
And the top of the waterproof layer 33a is fixed by pressing the metal fitting 36, and concrete 37 is placed on the upper surface of the waterproof layer 33a to form the pressing material layer.On the front surface of the waterproof layer 33b, bricks 39 are stacked while mortar 38 is piled up. The stack and the concrete 37 form a light-shielding protective layer for both the waterproof layers 33a and 33b to prevent the weather resistance from deteriorating (Shokai 58-89516).
Japanese Patent Laid-Open No. 63-27655).

A waterproof layer is also formed on the outer surface of the rising wall 34 of the rooftop tower.

The brick-laying method for forming the above-mentioned light-shielding protective layer is a troublesome work, and since it is a wet construction method, it takes time and labor and the construction period is prolonged.

Therefore, as described in the above publication, the light-shielding protective layer is made of a water-resistant panel, and the upper or lower end of the panel is fitted into a holder fixed to the rising portion 34 or the floor portion 32,
A technique has been devised in which the other end is fixed with a screw or rubber.

[Problems to be Solved by the Invention]

However, in the waterproofing method using the water resistant panel, the screwing of the other end of the water resistant panel is troublesome, and the rubber stopper lacks stability.

Under such circumstances, an object of the present invention is to provide a waterproofing method for a rising portion from a flat roof floor portion in which the water resistant panel can be easily attached and the attachment state is stable.

[Means for Solving the Problems]

In order to achieve the above-mentioned subject, in the present invention, following the above-mentioned floor roof waterproof layer of the flat roof, a waterproof layer is also formed on a rising portion from the floor, and a pressing material layer is formed on the floor waterproof layer. The surface of the rising waterproof layer is covered with a light-shielding and water-resistant panel, and the upper and lower ends of the panel are fitted and supported by the panel holder and the base holder above and below the rising portion. The depth of the downward groove of the sandwiching support part was increased, the depth of the upward fitting groove of the base holder panel fitting support part was reduced, and the upper end of the waterproof panel was fitted deeply into the groove of the support part of the panel holder. After that, the waterproof construction method was adopted in which the lower end of the panel was dropped into the groove of the support portion of the base holder and fitted.

[Action]

Since the waterproof method according to the present invention configured as described above is mounted by dropping the water resistant panel, the work is very easy, while the upper and lower ends of the water resistant panel are supported by fitting into the groove. The support will also be stable.

〔Example〕

FIG. 1 is a partially cutaway perspective view of an example of a waterproof construction part of a parapet part as an example of a rising part waterproof structure from a flat roof floor part according to the present invention, and FIG. It is a figure, 1 is a flat roof, 2 is a floor made of slab concrete, 3a is a waterproof layer such as a waterproof sheet formed on the floor 2, 3b is an inner surface of the parapet 4 following the waterproof layer 3a on the floor. It is a formed waterproof layer.

The upper end of the waterproof layer 3b is held by a panel holder 6 which also functions as a holding metal for preventing the peeling, and is fixed by an anchor bolt 7. Reference numeral 8 denotes a plug which is attached to the anchor bolt 7 and whose front side expands in all directions in concrete.

At the tip of the panel holder 6, there is provided a panel holding support portion 10 having a downward deep groove 9.

At the corner of the boundary between the lower concrete of the parapet 4 and the holding concrete 11 on the floor, a panel holding support that is an upward shallow groove is provided.
A base holder 12 having 18 is fixed by screwing a tapping screw 15 inserted into a hole 14 of a horizontal plate portion 13 formed from the lower side of the holder 12.

Reference numeral 16 is a joint made of expanded polyethylene disposed in the entry corner, and the tapping screw 15 is screwed into the joint 16. By screwing into the joints 16 in this way, it is not necessary to embed the plugs for the screws 15 therein when the concrete 11 is placed, the workability is good, and the concrete 11 divided by the expansion joints 16 is , It may expand or contract due to cold and warm, and the position of the plug 29 described below may shift, but there is no such fear.

Between the upper panel holder 6 and the lower base holder 12, panels 17 made of water resistant slate or the like are sequentially fitted in the left-right direction in FIG.

The panel 17 is fitted by first inserting the upper end side of the panel into the deep groove 9 of the upper panel holder 6 and then fitting the lower end side of the panel holding support portion 18 of the base holder 12 into the shallow groove portion. Match and drop to support.

19 and 20 are rising waterproof layers 3b at the rear end of the panel holder 6.
The sealing material is shown in the upper surface of the upper presser foot 21 and on the recessed portion on the rear surface.

FIG. 3 shows another example of the parapet rising from the flat roof floor. This parapet 4a has no chin and has a head 22 attached to the top.

In the case of this parapet 4a, the upper end of the rising waterproof layer 3c reaches the top of the parapet 4a, and the sealing material 23 is laid on the end of the parapet 4a. In this state, the headstock 22 is moved to the intermediate base holder 24 and the joint holder 27. Through the parapet
Supports 4a. The holder 6a which fits and supports the upper end of the water resistant panel 17a is attached to the intermediate base holder 24 with the bolt 25. The required number of joint holders 27 are provided at required intervals in the lengthwise direction of parapet 4a (left-right direction in FIG. 1). The other parts such as the base holder 12 that fits and supports the lower end of the waterproof panel 17a are the same as those in the case of FIG.

Reference numeral 26 denotes an anchor bolt for fixing the base holder 24 for supporting the headstock.

It should be noted that the present invention naturally includes a structure in which the base holder 12 is attached to the concrete 11 via the anchor bolts 28 as shown in FIG. 4 within the technical scope. In the figure, 29 is an embedded plug for anchor bolts.

〔effect〕

Since the present invention is configured as described above, the rising portion from the flat roof floor can be waterproofed by a smooth work, and the water-resistant panel can be stably attached.
