Description

The present invention relates to a method of installing a waterproof sheet, and more particularly, to a method of installing a waterproof sheet that forms a waterproof structure by being attached to a building opening in a fully closed state.

The shutter device is a device for opening and closing the opening of the building, and the widthwise side of the shutter curtain in the fully closed state is received in the guide groove of the guide rail erected on the left and right of the opening of the building. Is in contact with the floor surface. However, a general shutter device does not have a sufficient waterproof function, and in abnormal conditions such as heavy rain, between the shutter curtain width direction end and the guide rail, between the seat plate at the lower end of the shutter curtain and the floor, There is a risk of flooding from the outdoor side to the indoor side through the interlock portion connecting the slats.

Then, providing a waterproof function with respect to the existing shutter apparatus is examined, and such a waterproof apparatus is described in patent document 1, for example. The basic idea of this waterproofing device is to cover the outdoor side portion of the shutter curtain in a fully closed state with a sheet. In this structure, the side of the building opening is sealed using a holding member, and the lower end of the building opening is provided with a pressing member under the seat to prevent the waterproof sheet from curling up. In addition, in order to prevent the waterproof sheet from curling up more reliably, it is necessary to increase the weight of the pressing member.

Although such a waterproof sheet forms a waterproof structure by attaching to an existing shutter device, it is necessary to quickly install the waterproof sheet at the time of sudden heavy rain, etc. The attachment of the holding member and the increase in the weight of the pressing member are disadvantageous for the quick installation of the waterproof sheet.

[B] Inundation prevention structure [B-1] Overview In the present embodiment, the lower part of the shutter device on the outdoor side of the building opening fully closed state (corresponding to the assumed maximum water level + margin α, height H from the floor FL The waterproof sheet 5 is attached to the) to constitute a water immersion prevention structure or a waterproof device. The waterproof sheet 5 is made of a waterproof cloth. For example, the waterproof sheet 5 is a sheet whose surface is nylon and whose back surface is polyurethane, and has a certain degree of stretchability. The waterproof sheet 5 can be appropriately selected by those skilled in the art from known waterproof sheets available on the market, for example. As shown in FIG. 12 and FIG. 16, the waterproof sheet 5 is a horizontally rectangular sheet having a predetermined vertical width and a horizontal width, and for the lower part of the shutter curtain 2 on the outdoor side in the fully closed position, Push the left and right sides in the sheet width direction into the guide groove G, specifically, between the outdoor side edge 130 of the guide groove G and the width direction end of the outdoor side portion 200 of the slat 20 of the shutter curtain 2 The seat lower portion is attached by pressing it between the lower surface of the seat plate 21 (the landing portion 211) at the lower end of the shutter curtain and the floor surface FL. By doing this, the waterproof sheet 5 covers the front portion of the height H from the floor surface FL of the shutter curtain 2 in the fully closed position, and the three-way gap between the left and right sides and the lower end of the front portion It closes (refer FIG. 4, FIG. 21).

The vertical width (height dimension) of the waterproof sheet 5 may be a dimension higher than the assumed maximum water level in the installed state (estimated maximum water level + margin α, for example α = 100 mm), and the height dimension is at least from the floor surface It is larger than the vertical width dimension used for pushing height + α + lower end up to assumed high water level. For example, if the assumed maximum water level is 300 mm from the floor surface, it is 600 mm or more in consideration of the pressing amount at the lower end. The lateral width (length dimension) of the waterproof sheet 5 is at least larger than the opening width dimension + the width dimension used for left and right pressing. For example, when the opening width dimension is 2000 mm, it is 2400 mm or more in consideration of the left and right pushing amounts.

Here, since the width dimension of the building opening may differ depending on each site, the waterproof sheet 5 can be obtained by cutting the common waterproof sheet 6 into an arbitrary width dimension in accordance with the opening width dimension W of the installation location. It is like that. In this specification, the common waterproof sheet before cutting is referred to as “waterproof sheet 6 (see FIG. 10, FIG. 17)”, and the waterproof sheet after being cut according to the installation location is referred to as “waterproof sheet 5 (FIG. 12, FIG. See 16).

More specifically, the waterproof sheet 5 is used on the outdoor side of the guide groove G of the guide rail 1 together with the side pushing elements 7 using the side pushing elements 7 at the side portions at both ends in the width direction of the waterproof sheet 5. The lower portion of the tarpaulin 5 is pressed with the lower push-in element 8 together with the lower push-in element 8 by the edge 130 and the widthwise end of the indoor side portion 200 of the slat 20 of the shutter curtain 2 Side portion of the shutter curtain 2 in the fully closed posture (a predetermined height H from the floor FL, for example, H = about 400 mm) by pressing it between the lower surface of the seat plate 21 (landing portion 211) and the floor FL. While closing the gap at the lower end portion and covering the lower portion (from the floor surface FL to the height H) of the shutter curtain 2 from the outdoor side.

[C] Installation Step of Waterproof Sheet [C-0] Pre-Process First, the opening width dimension of the installed shutter device is measured. Specifically, the internal dimension between the left and right guide rails 1, that is, the opening width dimension W (see FIG. 1) is measured. The waterproof sheet 6 is cut so as to have a length corresponding to the measured value. In the present embodiment, the waterproof sheet 6 is cut into a length of “measurement value + 400 mm”. At the time of cutting, dimension lines can be referred to. By doing this, the waterproof sheet 5 of the first side area 51 (width dimension 200 mm) + the front area 50 (width dimension W ′) + the second side area 52 (width dimension 200 mm) is obtained. The waterproof sheet 5 illustrated in FIG. 12 is the first side area 51 (width dimension W1 = 200 mm) + central area 50 (width dimension W ′ = 700 mm + 10 mm × 2) + second side area 52 (width dimension W2 = 200 mm) ). The waterproof sheet 5 illustrated in FIG. 16 is the first side area 51 (width dimension W1 = 200 mm) + central area 50 (width size W ′ = 1000 mm + 10 mm × 2) + second side area 52 (width size W2 = 200 mm) ). The above-mentioned 20 mm is a width dimension of a portion to be pushed into the guide groove G together with the first side pushing element 7 and the second side pushing element 7 ′ in the first end area 500 and the second end area 501, respectively. . Note that the cutting position does not have to be strict, and the first side area 51 has a width that allows the left and right end portions to be closed by being pushed into the left and right guide grooves in the state as shown in FIG. The second side area 52 may be obtained. In the present embodiment, the width dimension W1 of the first side area is determined because the first side pushing element 7 is fixed in advance to the waterproof sheet 5, but the width dimension W2 of the second side area 52 is As a result after cutting, for example, it may be 180 mm or 220 mm. In addition, when the second side pushing element 7 'is actually pressed against the waterproof sheet 5, an area (right side guide groove G) located on the side (right side in the figure) of the second side pushing element 7' The width dimension of the pushed-in area can be varied by the set position of the second side pushing element 7 'in the actual site.

At one end of the central front area 50 on the tarpaulin 5, a first side pushing element 7 is fixed. Although the side positioning reference mark 7A for the setting of the second side push-in element 7 'is displayed on the waterproof sheet 5, in order to quickly install the waterproof sheet 5, the second side in advance It is desirable to mark the set position of the push-in element 7 '(the position where the first surface 70 is applied). The way of marking the set position of the second side push-in element 7 ′ is not limited, but, for example, the first side push-in element 7 together with the first side area 51 is actually in the guide rail groove G of the first guide rail 1. The second side pushing element 7 ′ is combined with the second side area 52 in a state in which the waterproof sheet 5 is pressed and the waterproof sheet 5 is pressed while the front area 50 is stretched along the outdoor side surface of the shutter curtain 2. The position of the second side push-in element 7 'is marked on the waterproof sheet 5 with an oil pen or the like after confirming that the front area 50 is in a stretched state by pushing into the guide rail groove G of the second guide rail. This marking position is a guide, and the setting position of the second side push-in element 7 'and the marking position do not necessarily have to be exactly in alignment at the time of installation.
