Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating and waterproofing device for a veranda, a flat roof or the like.

[0002]

2. Description of the Related Art Conventionally, as a heat insulating and waterproofing construction method for a veranda or a flat roof, for example, a large number of substantially rectangular heat insulating material blocks are laid on a floor to be waterproofed, such as a floor of a veranda, and the surface of these heat insulating material blocks. In addition, a method of coating a waterproof material made of a synthetic resin-coated metal plate or laying a synthetic resin waterproof sheet is already known.

Of these, according to the former method, the heat insulating material block and the waterproof material are fixed by hammering nails on the waterproof material and the heat insulating material block, and the latter method. According to the method, first, the heat insulating material block is fixed with a joining piece made of PVC steel plate or the like and a nail,
The waterproof sheet is stretched by covering the above with a synthetic resin waterproof sheet and joining required portions of the waterproof sheet to the joining piece.

[0004]

However, according to such a conventional method, in any case, the fixing nail penetrates the waterproof material and the heat insulating material block, or the joining piece and the heat insulating material block to form the base. It is difficult to drive a nail with a long dimension because it is driven into the vertical direction, and it is difficult to drive such a nail vertically to the base. If the nail is driven obliquely to the base, the length of drive to the base is short. As a result, the pulling strength of the nail is weak, and the base and heat insulating material block,
There is a problem that the fixing strength between the waterproof material and the heat insulating material block or the joining piece and the heat insulating material block becomes insufficient, and the cost of the nail having a long dimension is high.

In the case of heat-insulating and waterproofing of a veranda or a flat roof, the surface of the waterproof material or the waterproof sheet covered with the heat-insulating material block is usually a veranda or the like in order to make a water gradient on the surface of the heat-insulating and waterproofing portion. It is inclined so that it becomes gradually lower toward the side edge portion, so that the thickness of the heat insulating material block is gradually made thinner accordingly.

However, in this case, it is necessary to use nails having different lengths for driving in correspondence with the change in the thickness of the heat insulating material block. Fixing work is very troublesome, it is troublesome, preparation and management of parts such as nails to be used are very complicated, and there is a problem that it is not easy to apply heat insulation and waterproofing to a veranda or a flat roof.

An object of the present invention is to solve the above-mentioned problems of the prior art and to lay a heat insulating material block on a base to be waterproofed such as a veranda and to perform heat insulating and waterproofing, the adjacent heat insulating material blocks are By providing a gap between them and inserting a pressing member into the gap to press the side edge portion of the heat insulating material block, the heat insulating material block can be secured by using a fixture such as a nail having a short length and a certain size. It can be fixed with good workability and with sufficient fixing strength, and even if the thickness of the heat insulating block to be used changes gradually due to the water gradient, a nail with a short single length or Since it is only necessary to use fixing tools such as screws, so it is possible to use so-called commercial products for the fixing tools, the cost of parts is low, the preparation and management of parts are easy, and eventually the veranda or flat roof etc. Insulation prevention May perform installation easily and inexpensively,
It is to provide a heat insulating and waterproofing device such as a balcony.

[0008]

In order to achieve the above object, the present invention provides a waterproof material made of a synthetic resin-coated metal plate on a base material such as a veranda to be waterproofed. A heat insulating and waterproofing device in which a large number of substantially rectangular heat insulating material blocks are laid as seen from a plane joined to the surface,
A gap having a required width is provided between the waterproof material-covered heat insulating material blocks which are adjacent to each other, and a pressing member having a substantially U-shaped cross section is fitted into the gap, the pressing member having protruding side edge portions on both left and right sides.
The bottom wall portion of the pressing member is fixed to the base with a fixture such as a nail while being placed on the base, and the waterproof material-covered heat insulating material block on the same side by the left and right projecting side edges of the pressing member, respectively. The side edges of the strip-shaped connecting sheet are covered with a synthetic resin band-shaped connecting sheet so as to straddle the holding member, and both side edges of the band-shaped connecting sheet are close to the side edges of the adjacent waterproof material-covered heat insulating material blocks. It features heat-insulating waterproof devices such as balconies, which are joined to the surface of the waterproof material.

Next, the invention according to claim 3 is such that a large number of heat insulating material blocks which are substantially rectangular in plan view are laid on a base material such as a veranda to be waterproofed, and synthetic resin or synthetic rubber is placed on the heat insulating material block. A heat insulating waterproof device in which a waterproof sheet is stretched, and a gap having a required width is provided between adjacent heat insulating material blocks, and protruding side edge portions are provided on both left and right sides in the gap. The holding member having a substantially U-shaped cross section is fitted therein, and the bottom wall portion of the holding member is fixed to the base by a fixture such as a nail while being placed on the base, and the left and right protrusions of the holding member are A heat insulating and waterproofing device such as a veranda is characterized in that the side edge portions of the heat insulating material block on the same side are held down by the side edge portions, and a waterproof sheet is stretched over the heat insulating material block and the holding member.

In any of the heat-insulating and waterproofing devices such as the veranda of the inventions according to the first and third aspects, in any case, the pressing member having a substantially U-shaped cross section is provided in the upper opening concave portion at the center thereof. Since the joint embedding material having substantially the same height as the recess is fitted, the foot of the person does not fit into the depression of the pressing member even if a person rides on the veranda or the like after heat insulation and waterproofing. .

In the above, the groundwork to be waterproofed such as the balcony is composed of, for example, a lightweight concrete plate and plywood placed on the lightweight concrete plate. It may be configured by itself or a wooden plate material itself, or may be configured by placing a plywood or the like on these.

As the heat insulating material block, resin foam such as polystyrene foam, polyurethane foam and polyethylene foam is used. Of these, polystyrene foam is economically advantageous.

The thickness of the heat insulating material block is about 25 to 100 mm
The width and the length of the heat insulating material block are usually 1 m and 2 m, but the size and shape of such a heat insulating material block are of course arbitrary.

As the waterproof material made of a synthetic resin-coated metal plate used in the invention described in claim 1, for example, a core material is a steel plate having a thickness of 0.2 to 1.5 mm, and both surfaces thereof have a thickness of 0.2. It is preferable to use a long plate or a single plate provided with a coating layer made of polyvinyl chloride resin having a thickness of up to 1.0 mm.
preferable. Such a vinyl chloride resin-coated steel sheet has good workability such as cutting, and its surface can be completely welded by a solvent such as tetrahydrofuran. As a waterproof material,
Any plate having corrosion resistance such as a plate material such as a steel plate having one surface or both surfaces coated with another synthetic resin can be used.

The waterproof material usually has the same shape and size as the surface shape of the heat insulating material block, and the surface of the heat insulating material block is
Pre-bonded.

Here, as the adhesive for joining the heat insulating material block and the waterproof material, a general-purpose adhesive may be used.
Examples thereof include epoxy-based, urethane-based and rubber-based adhesives.

The pressing member having a substantially U-shaped cross section is made of a synthetic resin-coated metal plate, like the waterproof material, but it may be a molded product made of a synthetic resin plate. The width of the recess at the center of the pressing member is, for example, 10 to 30 mm, preferably 15 to 25 mm,
The width may be such that a fixing tool such as a nail or a screw having a short length and a certain size can be driven.

At the upper end portions of the left and right side walls of the pressing member, there are provided bulging side edges extending to the left and right sides respectively. The width of these bulging side edges is the same as that of the waterproof material coating. Any material can be used as long as it can hold down the side edge of the heat insulating material block, for example, 10 to 40 mm, preferably 20 to 3
It is 0 mm.

Further, as the fixture for fixing the bottom wall portion of the pressing member to the base, nails, screws, etc. are used, but these penetrate the bottom wall portion of the pressing member and are driven or screwed into the base. Since it is sufficient, a short length having a length of, for example, 15 to 30 mm and a single length can be used.

As the belt-like connecting sheet, a sheet made of thermoplastic synthetic resin such as soft polyvinyl chloride, or a vulcanized rubber type sheet such as EPDM or a non-vulcanized rubber type sheet is used. In this respect, it is preferable to use a soft polyvinyl chloride sheet. The thickness of this connecting sheet is usually about 1.0 to 2.0 mm.

Various kinds of adhesives can be used as an adhesive for joining the both side edges of the strip-shaped connecting sheet covered on the pressing member and the waterproof material made of a synthetic resin-coated metal plate. In particular, when both bonding surfaces are made of polyvinyl chloride resin, tetrahydrofuran alone or a small amount of vinyl chloride resin or a resin such as a copolymer of vinyl chloride and vinyl acetate is dissolved in tetrahydrofuran. It is preferable to use a solution-type welding agent from the viewpoint of welding property. In addition, an epoxy-based, urethane-based, or rubber-based adhesive or the like may be used as the adhesive for joining the waterproof material and the strip-shaped connecting sheet.

When both the joint surface of the waterproof material and the connecting sheet are made of thermoplastic synthetic resin,
It is also possible to join the two by heat fusion without using an adhesive.

As the joint embedding material, for example, one having a substantially inverted U-shaped cross section and made of a synthetic resin-coated metal plate or a molded product of a synthetic resin is used. Alternatively, a solid rod-shaped member may be used. In short, any member may be used as long as it is fitted in the recess of the pressing member having a substantially U-shaped cross section so that a person can walk, for example.

The waterproof sheet used in the third aspect of the present invention is a thermoplastic synthetic resin sheet such as soft polyvinyl chloride, polyethylene or polypropylene, or a vulcanized rubber-based sheet such as EPDM or non-vulcanized rubber. Although a system sheet or the like is used, it is particularly preferable to use a soft polyvinyl chloride sheet in terms of adhesion between the sheets. The thickness of this waterproof sheet is usually about 1.0-
It is 2.0 mm.

Various kinds of adhesives can be used as the adhesive for joining the waterproof sheet and the left and right projecting side edges of the pressing member, and the pressing member and the strip in the invention according to claim 1 are used. Similar to the case of joining with the connecting sheet, especially when the joining surfaces of the waterproof sheet and the holding member are both made of polyvinyl chloride resin, tetrahydrofuran alone or a small amount of vinyl chloride resin in tetrahydrofuran, or chloride It is preferable to use a solution-type welding agent in which a resin such as a copolymer of vinyl and vinyl acetate is dissolved, from the viewpoint of welding property. In addition, an epoxy-based, urethane-based, or rubber-based adhesive may be used as the adhesive for joining the waterproof sheet and the pressing member.

When both the waterproof sheet and the pressing member are made of thermoplastic synthetic resin, they may be joined by heat fusion without using an adhesive.

Further, a curing sheet may be interposed between the heat insulating material block and the waterproof sheet. Here, the curing sheet has a curing action for protecting the waterproof sheet,
The plasticizer from the soft synthetic resin forming the waterproof sheet serves to prevent migration of the plasticizer to the heat insulating material block.

As such a curing sheet, for example, a foamed sheet having a thickness of 1 to 4 mm made of an independent foamed body of a thermoplastic resin such as polyethylene, polypropylene, polyurethane and polyvinyl chloride, or these foamed sheets,
For example, a composite sheet in which a reinforcing layer made of a film of polyethylene, polypropylene, polyvinyl chloride and polyester or a woven or non-woven fabric made of these resins is attached to the entire surface by an adhesive or by heating is used. When the waterproof sheet is made of, for example, a soft vinyl chloride sheet and the heat insulating material block is made of polystyrene or a foam of polyvinyl chloride, in order to prevent the plasticizer from migrating from the waterproof sheet, in particular, It is desirable to use a polyethylene or polypropylene film, or a foam thereof, or a composite sheet of a foam of these resins and a resin film, a woven cloth or a non-woven cloth.

[0083]

As described above, in the heat insulating and waterproofing device for a veranda or the like according to the first aspect of the present invention, a gap having a required width is provided between the waterproofing material-covered heat insulating material blocks adjacent to each other. A pressing member having a substantially U-shaped cross section is fitted therein, and the side edges of the waterproof material-covered heat insulating material block on the same side are pressed down by the left and right projecting side edges of the pressing member. The pressing member is fixed on the base in the gap, and in this state, the bottom wall portion of the pressing member is fixed to the base by a fixing tool such as a nail. Therefore, as such a fixing tool, a nail or a screw having a single length, which is short enough to be penetrated through the bottom wall portion of the pressing member and driven into the base or screwed, can be used. Also, unlike the conventional method, there is no need to drive the nail diagonally into the substrate, and the nail can be reliably driven vertically to the substrate, so the nail drive length to the substrate is sufficient. As a result, the nail pull-out strength is large, and the waterproof material-covered heat insulating material block has a sufficiently large fixing strength.

In the case of heat insulating and waterproofing of a veranda or flat roof, the surface of the waterproof material is usually inclined so as to gradually lower toward the side edge of the veranda or the like in order to obtain a water gradient. It is said that the thickness of the block gradually changes accordingly, but even in such a case, nails or screws having a short length and a single length can be used, and therefore, the waterproof material-coated heat insulating material block Fixing work is extremely easy and requires no effort. In addition, since it is only necessary to use parts such as nails that are short and have a certain size, it is possible to use so-called commercial products for fixing tools such as nails, the parts cost is low, and parts preparation and management are easy. As a result, it is possible to easily and inexpensively perform the heat insulating and waterproofing work on the veranda, the flat roof, and the like.

Then, the strip-shaped connecting sheet is covered so as to straddle the pressing member, so that both side edges of the strip-shaped connecting sheet are
Since the waterproof material is bonded to the waterproof material surface near the side edge of the adjacent waterproof material-insulated block, the pressing member cannot be seen from the outside, and the finish of the heat-insulating waterproof construction such as the veranda is very clean and the appearance is good. It has the effect of being excellent.

Further, by fitting a joint embedding material having substantially the same height as the concave portion in the upper opening concave portion of the central portion of the pressing member having a substantially U-shaped cross section, the upper portion of the veranda after heat insulation and waterproofing is applied. For example, even if a person walks, there is an advantage that the heel of the shoe of the pedestrian or the like does not fit into the concave portion of the pressing member and the person can walk.

Further, in the heat insulating and waterproofing device such as the veranda according to the third aspect, as described above, a gap having a required width is provided between the adjacent heat insulating material blocks, and the cross section is formed in the gap. A substantially U-shaped pressing member is fitted in, and side edges of the heat insulating material block on the same side are pressed down by the left and right projecting side edges of the pressing member. Therefore, in the same manner, for fixing the pressing member, it is sufficient to fix the pressing member to the base using a fixture such as a nail having a short length and a constant size. Since the work of driving such nails is extremely simple, the heat insulating block Can be fixed with very good workability and sufficient fixing strength.

Further, even when the thickness of the heat insulating material block is changed in order to obtain a water gradient on the surface of the heat insulating and waterproofing construction, a fixture such as a nail having a short length and a single length is always used. Just fix the bottom wall of the pressing member to the base using
Since the heat insulating material block can be fixed, the work of fixing the heat insulating material block is extremely easy and requires no effort. In addition, since it is only necessary to use parts such as nails that are short and have a certain size, it is possible to use so-called commercial products for fixing tools such as nails, the parts cost is low, and parts preparation and management are easy. As a result, it is possible to easily, inexpensively and surely perform the heat insulating and waterproofing construction of the balcony or the flat roof.

After the side edges of the heat insulating material block are held down by the holding member, the waterproof sheet is stretched over them, so that the holding member cannot be seen from the outside and the heat insulating and waterproofing of the veranda is performed. The finish is very beautiful and the appearance is excellent.

Further, by fitting a joint embedding material having substantially the same height as the concave portion in the upper opening concave portion of the central portion of the pressing member having a substantially U-shaped cross section, it is possible to put it on the veranda after heat insulating and waterproofing. Even if a person gets on, there is an advantage that the foot of the person does not fit into the concave portion of the pressing member.
