Further, the method of removing the second old metal roof plate and newly installing it has a problem that the construction period and cost are too large. Furthermore, in the method of laying a heat insulating material on the third metal roof plate and covering the surface of the heat insulating material with a waterproof sheet, the work of installing each heat insulating material is very troublesome, laborious, and costly. There was a problem that became.

An object of the present invention is to solve the above-mentioned problems of the prior art and to repair a sheet metal roof that requires repair or repair by waterproofing the sheet, with excellent workability, easily and reliably. Can be carried out in
There is a need to provide a sheet waterproofing device for a metal sheet thatched roof, which can be lightened at a low repair cost.

[0005]

In order to achieve the above-mentioned object, the present invention lays a large number of metal roof plates having parallel peaks and flat valleys so as to partially overlap each other. In a roof with a metal plate, a metal roof plate is laid and arranged on a mountain portion of the metal roof plate by passing a required number of base plates made of a heat insulating material or a fireproof plate material in a substantially rectangular shape as viewed from above. The base plate pressing member that has an upper wall portion for joining the waterproof sheet and that protrudes upward from the top wall of the mountain portion is attached to the required portion of the base plate, and the cut portion is provided at a predetermined position of at least one side edge of each base plate. Are provided, the side edges of the base plate material are fitted to the corresponding base plate pressing members on the metal roof plate at the cut portions, and each base plate material is fixed on the metal roof plate, and all base materials are fixed. Waterproof sheet 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.

In the above, when repairing or repairing a metal roof plate, the base plate material which is passed over the mountain portion of the roof plate and laid in order to cover the unevenness of the roof plate surface is a plate material having a so-called flat surface. Anything can be used,
Generally, a heat insulating material or a fireproof plate material that is substantially rectangular when viewed from above is used. If a heat insulating material is used as the base plate material, waterproof and heat insulating properties can be obtained for the roof after repair, and if a fire resistant plate material is used, fire resistance can be obtained.

Here, as the heat insulating material, for example, resin foam such as polystyrene, polyvinyl chloride, polyurethane and polyethylene is used. Of these, it is economically advantageous to use polystyrene foam. Is.

Further, examples of the fire resistant plate material include a concrete plate, a lightweight asbestos plate, a gypsum board and the like.

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-based sheet or a rubber asphalt-based sheet is used. It is preferable to use a soft polyvinyl chloride sheet.

The base plate pressing member is a metal plate, or a steel plate (hereinafter referred to as a vinyl chloride steel plate) coated with vinyl chloride resin on one or both sides to improve adhesion, or a hard or semi-hard synthetic resin plate. Use a plate material such as.

Here, the base plate material pressing member projects, for example, above the top surface of the top wall of the mountain portion of the metal roof plate and has a substantially U-shaped cross section having a waterproof sheet joining upper wall portion and left and right side wall portions. It is good to use one.

This base plate pressing member having a substantially inverted U-shaped cross section is covered on the mountain portion of the metal roof plate, and the lower end portions of the left and right side wall portions of the base plate material retainer on the right and left inclined surface portions of the roof plate mountain portion. For example, it is attached using blind rivets. In addition,
It is preferable to use a blind rivet for fixing the base plate material pressing member rather than using a tapping screw. Because the thickness of the metal roof is usually 0.6-0.8
This is because it is so thin as mm that it is difficult to fix with tapping screws.

By mounting the base plate pressing member having a substantially inverted U-shaped cross section, a space for inserting the side edge of the base plate between the upper surface of the top of the mountain roof of the metal roof plate and the lower surface of the upper wall of the pressing member. Is formed.

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

The side edge portions of the substantially rectangular base plate material are held down by the holding members at one or a plurality of points. The base plate material is held down by the holding members at the four corners and the side edge portions of the base plate material. 1 in the middle of
It may be held down by a holding member at one or two points.

When the base plate material is held down by the holding members at the four corners thereof, the plate-shaped side wall portions of the cross-section substantially inverted U-shaped holding member are provided at the ridge-side and eave-side side edges of the four corners of the base plate material, respectively. There is a vertical notch for inserting the base plate material over the mountain part of the metal roof plate, and the vertical notch part of the side edge part of each base plate material is provided. At the same time that the plate-shaped side wall portion of the pressing member is fitted, the side edge portion near the corner from the vertical cut portion of the base plate material is between the lower surface of the upper wall portion of the pressing member and the upper surface of the mountain top wall of the roof plate. It is inserted into the space. Therefore, the side edge portions of each base plate material are held at the two corner portions.

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

Among 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 are usually one base plate material having a substantially inverted U-shaped cross section. Half of the side edge portions of the ridge-side and eave-side base plate members are inserted together inside the presser member, but in some cases, one inside edge of the base plate member presser member with a substantially inverted U-shaped cross section is used. It is also possible to insert only the side edges of the base plate material.

Further, each of the base plate materials laid out on the metal roof plate, except for those arranged on both outer sides of the ridge side and the eaves side, has a presser foot at each side edge of the ridge side and the eaves side. It is held down by a member. It should be noted that the base plate material arranged on the most ridge side of the roof is held down by the holding member only at the side edge portion on the eaves side. On the other hand, in the base plate member arranged on the most eaves side of the roof, only the side edge of the ridge side of the base plate member is held by the holding member.

Then, the side edges on the opposite sides of the base plate materials arranged on both the ridge side and the eaves side of the roof are covered with a vinyl chloride steel plate or the like having a substantially L-shaped cross section or a substantially U-shaped cross section, respectively. The member is integrally and watertightly connected to the roofing material by a conventional means.

Further, the left and right outer side edges of the base plate material arranged on both the left and right gable sides of the roof are called "Keraba wrapping plates" each having a substantially inverted L-shaped cross section and made of, for example, a vinyl chloride steel plate or the like. It is integrally and watertightly joined to the roofing material by conventional means using the covering member.

In this way, the waterproof sheets are covered on the upper surfaces of all the base plate materials that are laid and lined up on the mountain portion of the metal roof plate, and the waterproof sheet portion corresponding to the upper wall portion of the base plate material holding 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 of the covering member that covers the side edges of the base plate at the ridge side and the eaves side of the roof, and on the left and right gable sides of the roof, respectively. .

Here, as an adhesive agent for bonding a required portion of the waterproof sheet to the upper surface of the upper wall portion of the base plate material pressing member,
Epoxy, urethane, and rubber adhesives can be used, but especially when both the waterproof sheet and the upper wall surface of the base plate pressing member are made of vinyl chloride resin, tetrahydrofuran alone or a small amount of tetrahydrofuran It is preferable to use the solvent-type adhesive in which the vinyl chloride resin is dissolved, because an adhesive effect with excellent durability is produced.
When both the waterproof sheet and the upper wall portion of the base plate material pressing member are made of thermoplastic synthetic resin, they can be joined by heat fusion without using an adhesive.

A curing sheet (so-called insulating sheet) may be interposed between the waterproof sheet and the base sheet material made of the above-mentioned heat insulating material or fireproof sheet material.

Here, the curing sheet has a curing action 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 migration-preventing action of preventing the plasticizer from the waterproof sheet from migrating to the heat insulating material.

Examples of such a curing sheet include a foamed sheet of a thermoplastic resin such as polyethylene, polypropylene, polyurethane and polyvinyl chloride, or a foamed sheet of the same such as a film of a thermoplastic resin such as polyethylene or a resin thereof. A composite sheet to which a reinforcing layer made of a woven or non-woven fabric is attached is used.

When such a curing sheet is interposed between the base plate material and the waterproof sheet, first, the upper wall portion of the holding member for fixing the base plate material passed on the mountain portion of the metal roof plate is fixed. By notching the curing sheet portion corresponding to the upper surface, and then by bonding or hot air fusion with an adhesive between the upper surface of the upper wall of the pressing member and the back surface of the corresponding portion of the waterproof sheet at the notched portion of this curing sheet. , A waterproof sheet is stretched.

According to the above sheet waterproofing device, in a metal plate thatched roof that needs to be repaired or refurbished, a base plate pressing member is preliminarily attached to a required portion of a mountain portion of a metal roof plate, while a heat insulating material or a fireproof material is used. A cut portion is provided at a predetermined position on at least one side edge portion of a base plate material made of a flexible plate material or the like.

Therefore, during the repair work, the base plate material is laid out by laying it on the mountain portion of the metal roof plate, and at the same time, the corresponding pressing member is fitted to the notch of the side edge of each base plate material. By doing so, each base plate material can be quickly fixed to the metal roof plate. For this reason, the workability is very good, the work is simple, and each base plate material can be securely fixed.

Then, a waterproof sheet is covered on the upper surfaces of all the base plate materials, and the required portions of the waterproof sheet are joined to the upper surface of the upper wall portion of the pressing member to stretch the waterproof sheet. Since it is not necessary to use such a joining piece, the repair work by waterproofing the sheet is very easy and the repair cost is low. In addition, since the roof of the metal plate roof is refurbished by using the base plate material made of a heat insulating material or a fireproof plate material and the waterproof sheet, and the base plate pressing member made of a vinyl chloride steel plate or the like, the weight can be reduced.
