An object of the present invention is to provide a sheet waterproofing device for a metal-plated roof which can be reduced in cost and can achieve weight reduction.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention lays a large number of metal shingles having parallel ridges and flat valleys partially overlapping each other. In a metal sheet roof that has been made, a required number of base materials made of a heat insulating material or a fire-resistant sheet material, etc., which are approximately square when viewed from a plane, are laid and laid on the mountain part of the metal roof sheet, and the metal roof sheet is laid. At a required portion of the crest portion, a base plate material holding member projecting above the top wall of the crest portion and having a waterproof sheet joining upper wall portion is attached, and a cut portion is formed at a predetermined position on at least one side edge of each base plate material. Are provided, and the side edges of the base plate are fitted to the corresponding base plate holding members on the metal roof plate at the cut portions, and each base plate is fixed on the metal roof plate, and all the base plates are fixed. A waterproof seam placed on the top of the plate Required portion is joined to the wall upper surface on the pressing member, the waterproof sheet is stretched, and the gist of the sheet waterproofing device for a metallic Itabuki roof.

[0006] In the above description, when repairing or repairing a metal roofing sheet, the base sheeting that is laid and laid over the ridges of the roofing sheet to cover the unevenness of the surface of the roofing sheet is a sheet material having a so-called flat surface. Anything can be used,
Usually, a substantially rectangular heat insulating material or a fire-resistant plate material or the like is used as viewed from the plane. If a heat insulating material is used as the base plate, the roof after the renovation can be provided with waterproof and heat insulating properties, and if a fire resistant plate or the like is used, fire resistance can be obtained.

Here, as the heat insulating material, for example, a resin foam such as polystyrene, polyvinyl chloride, polyurethane, or polyethylene is used. Among them, it is economically advantageous to use a polystyrene foam. It is.

[0008] Examples of the fire-resistant board include concrete boards, lightweight asbestos boards, and gypsum boards.

As the waterproof sheet, a sheet made of a thermoplastic synthetic resin such as soft polyvinyl chloride, polyethylene, or polypropylene, or a non-vulcanized rubber sheet or a rubber asphalt sheet is used. It is preferable to use a soft polyvinyl chloride sheet.

[0010] The base plate material holding member may be a metal plate, a steel plate coated on one or both sides with a vinyl chloride resin to improve adhesion (hereinafter referred to as a PVC steel plate), a hard or semi-hard synthetic resin plate. Use a plate material such as

Here, the base plate material holding member is, for example, a substantially inverted U-shaped cross section which protrudes upward from the upper surface of the top wall of the peak portion of the metal roof plate and has a waterproof sheet joining upper wall portion and left and right side walls. It is good to use those.

[0012] The base plate material holding member having a substantially inverted U-shaped cross section is covered on the ridge portion of the metal roof plate, and the lower ends of the left and right side walls are provided on both left and right inclined surfaces of the roof plate ridge portion. For example, it is attached using blind rivets. In addition,
It is more preferable to use a blind rivet than to use a tapping screw for fixing the base plate material holding member. This is because the thickness of a metal roof plate is usually 0.6 to 0.8.
This is because it is very thin with mm, and it is difficult to fix it with tapping screws.

[0013] By attaching a base plate material holding member having a substantially inverted U-shaped cross section, a space portion for inserting a base plate side edge portion between the upper surface of the top portion of the metal roof plate and the lower surface of the upper wall of the holding member. Is formed.

On the other hand, at least a predetermined portion of at least one side edge of a substantially rectangular base plate made of a heat insulating material or a fire-resistant plate,
For example, a notch is provided for fitting a side wall of a base plate material holding member having a substantially inverted U-shaped cross section.

The side edges of the substantially rectangular base plate are held down by the holding members at one or a plurality of positions. The base plate is held at four corners by the holding members. One in the middle of the length of
There is a case where the holding member is pressed down at the place or at two places.

In the case where the base plate is held down by the holding members at the four corners, the plate-like side wall of the substantially inverted U-shaped holding member is provided at the four corners of the base plate at the ridge side and the eave side, respectively. A vertical notch is provided for fitting the base plate, and while laying the base plate over the ridges of the metal roof plate, the vertical cuts correspond to the vertical cuts at the side edges of each base plate. At the same time that the plate-like side wall of the holding member is fitted, the side edge portion near the corner from the vertical cut portion of the base plate material is located between the lower surface of the upper wall of the holding member and the upper surface of the top wall of the roof plate. It is inserted in the space. Therefore, the side edges of the respective base plate members are held down at two locations of the corner portions.

On the other hand, when the pressing member is pressed down at one or two positions in the middle of the length of the side edge portion of the base plate material, the corresponding one of the middle portions of the side edge portions of each base plate material or At two locations, two notches for fitting the left and right side walls of the substantially inverted U-shaped pressing member in cross section are provided vertically at each location and opposed to each other. Then, while laying and laying the base plate material on the mountain portion of the metal roof plate, the plate-shaped side wall portion of the corresponding holding member is formed in two vertical cut portions in the middle of the length of the side edge portion of each base plate material. At the same time, the side edge portion between the two vertical cut portions of the base plate is inserted into the space between the lower surface of the upper wall of the holding member and the upper surface of the top of the roof plate. . Therefore, the side edge portion of each base plate material is held down at one or two places in the middle.

Of the base plate materials laid on the metal roof plate, the side edge portions of the base plate materials adjacent to the ridge side and the eave side usually have one cross-section substantially inverted U-shaped base plate material. The side edges of the ridge-side and eave-side base plate materials are inserted into the inside of the holding member half each, and in some cases, one inside plate member holding member having a substantially inverted U-shaped cross section is inserted inside. Only the side edges of the base plate may be inserted.

Each of the base plate materials laid on the metal roof plate, except those arranged on both outer sides of the ridge side and the eave side, is provided at both side edges of the ridge side and the eave side, respectively. It is held down by the member. In addition, only the side edge part of the eaves side of the base plate material arranged on the most ridge side of the roof is held down by the holding member. On the other hand, the base plate material disposed on the most eaves side of the roof has only the side edge on the ridge side thereof held down by the holding member.

The opposite side edges of the base plate materials disposed on both the ridge side and the eaves side of the roof are respectively coated with a PVC steel plate having a substantially L-shaped cross section or a substantially U-shaped cross section. It is integrally and watertightly connected to the roofing material by ordinary means using members.

The left and right outer side edges of the base plate disposed on both the left and right sides of the roof are referred to as "kera wrappers" each having a substantially inverted L-shaped cross section made of, for example, a PVC steel plate or the like. And a watertight connection to the roofing material by conventional means.

In this way, the waterproof sheet is put on the upper surface of all the base plate materials that are spread and laid out on the mountain portion of the metal roof plate, and the waterproof sheet portion corresponding to the upper wall portion of the base plate pressing member is provided. The waterproof sheet is stretched by joining the back surface to the upper surface of the upper wall portion of the pressing member. The outer peripheral edge of the waterproof sheet is joined to the upper surface of the upper wall portion of the covering member that covers the side edge of the base plate material at the ridge side and eave side of the roof, and at the outer peripheral edge of the left and right wives. .

Here, as an adhesive for joining a required portion of the waterproof sheet to the upper surface of the upper wall portion of the base plate material holding member,
Epoxy-based, urethane-based, and rubber-based adhesives may be used.Especially, when both the waterproof sheet and the upper wall surface of the base plate holding member are made of vinyl chloride resin, tetrahydrofuran alone or a small amount of tetrahydrofuran is used. It is preferable to use a solvent-type adhesive in which vinyl chloride resin is dissolved, since an adhesive effect having excellent durability is produced.
In the case where both the waterproof sheet and the upper wall portion of the base plate pressing member are made of a thermoplastic synthetic resin, they can be joined by heat fusion without using an adhesive.

In some cases, a curing sheet (so-called insulating sheet) may be interposed between the base sheet made of the above-mentioned heat insulating material or fire-resistant board and the waterproof sheet.

The curing sheet has a curing effect of protecting the waterproof sheet. For example, when the heat insulating material is covered with a waterproof sheet made of a plasticizer-containing synthetic resin such as soft polyvinyl chloride, It also has a plasticizer transfer preventing effect of preventing transfer of the plasticizer from the waterproof sheet to the heat insulating material.

As such a curing sheet, a foamed sheet of a thermoplastic resin such as polyethylene, polypropylene, polyurethane and polyvinyl chloride, or a film of a thermoplastic resin such as polyethylene or a resin of these foams may be used. A composite sheet to which a reinforcing layer made of the woven or nonwoven fabric is attached is used.

In the case where such a curing sheet is interposed between the base plate and the waterproof sheet, first, the upper wall portion of the holding member for fixing the base plate passed over the mountain portion of the metal roof plate. The curing sheet portion corresponding to the upper surface is cut out, and then the upper surface of the upper wall of the pressing member and the back surface of the corresponding portion of the waterproof sheet are joined or hot-air-fused with an adhesive at the notch portion of the curing sheet. , A waterproof sheet is stretched.

[0028]

According to the above-mentioned sheet waterproofing device, for a metal-plated roof that needs to be repaired or refurbished, a base plate material holding member is previously attached to a required portion of a metal roof shingle, while a heat insulating material or a fire-resistant material is used. A cut portion is provided at a predetermined position on at least one side edge of a base plate material made of a conductive plate material or the like.

Therefore, at the time of the renovation work, the base member is passed over the mountain part of the metal roof plate, and at the same time, the corresponding holding member is fitted into the cut portion at the side edge of each base plate. By proceeding, each base plate material can be quickly fixed to the metal roof plate. Therefore, the workability is very good and simple, and each base plate can be securely fixed.

Next, a waterproof sheet is put on the upper surface of all the base plate materials, and a required portion of the waterproof sheet is joined to the upper surface of the upper wall of the holding member, and the waterproof sheet is stretched. It is not necessary to use such a joint piece, the repair work by waterproofing the sheet is very simple, and the repair cost is low. In addition, since the repair of the metal sheet roof is performed using a base plate material and a waterproof sheet made of a heat insulating material or a fire-resistant plate material, and a base plate material holding member made of a PVC steel plate or the like, the weight can be reduced.
