Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of insulating and waterproofing outdoor exteriors mainly used for roofs or outer peripheries of buildings, large tanks, and the like.

Conventionally, for the insulation and waterproofing work of the above structures,
For example, as shown in Figure 1, for flat roofs, slab 1
A waterproof sheet 2 is placed on top of the waterproof sheet 2, and a panel-shaped waterproof material 3 whose main body is a heat insulating material 3a made of glass wool, foamed material, etc. is attached to the top surface with a skin 3b such as aluminum foil on the surface. In many cases, waterproof tape 4 was attached to the joints of each waterproof material 3, and a waterproof cover made of a sheet or sheet metal was further placed on top of the waterproof tape 4.

In addition, a sheet metal exterior using a stainless steel plate or the like has a structure in which a sufficient base is formed, multiple waterproofing layers and heat insulation layers are provided, and the sheet metal exterior is applied on top of that.

However, in these conventional construction methods, if the waterproofing material is made of a single layer, if the skin is damaged, water will immediately seep into the waterproofing material and the waterproofing function will be immediately impaired. In addition to laying the ground, various types of waterproof foundations must be formed, and this foundation must be completely perfect over the entire surface so that it can withstand water flowing from the above-mentioned damaged areas at unspecified locations. However, there were many uneconomical problems and problems in terms of material costs, etc.

Furthermore, in conventional construction methods, methods such as pasting tape, caulking, or fitting T-shaped sections into the joints have been used to treat the joints of waterproofing materials, as shown in the figure, but these methods do not respond to changes in the expansion and contraction of the waterproofing material. However, there were drawbacks such as damage to the area and water leakage.

The present invention aims to provide a heat insulation and waterproof construction method that eliminates or improves these drawbacks.

The illustrated embodiment will be described in detail below. The waterproofing material 11 shown in FIG. For example, the insert material 12 made of a material with a plate thickness of 0.05
A box-shaped outer case 1 made of a metal plate such as a thin stainless steel plate of ~0.2 mm or vinyl chloride, etc.
3, or by further vacuum sealing. If vacuum sealing is not used, it is desirable to bond the insert 12 and the upper and lower surfaces of the outer case with an adhesive to prevent the skin from lifting up.

This waterproofing material 11 can be manufactured in multiple widths to facilitate dimension matching at the actual construction site, and its length can be made to match the construction dimensions of the roof or rooftop, or it can be transported. In order to facilitate loading onto a truck, various sizes and lengths can be provided. In normal cases, it is standardized, for example, 1 m x 2 m or 90 cm x 180 cm.

3 and 4 are cross-sectional views showing an example of construction on a flat roof using the above-mentioned waterproofing material, in which a small amount of the above-mentioned waterproofing material 11 is placed on the slab 14 up to the lower end of the rising part 15 at the end thereof. They are arranged in alignment with a joint interval of 16. The purpose of this joint spacing 16 is to prevent the roof surface from being deformed due to expansion and contraction changes due to thermal expansion or the like of the waterproofing material 11.

The waterproof sheet 1 covers the inner surface from the top of the rising portion 15.
7, and the upper end of the waterproof sheet 17 is fixed by pressing with a presser 18 at the outer edge of the upper surface of the rising part 15, and at the lower corner part, the lower surface of the end is covered with the upper surface of the waterproof material 11 laid there. Corners are treated by gluing or waterproof coating. In addition, a ventilation portion 19 is provided on the inner surface of the rising portion 14 through the waterproof sheet 17, and dehumidification is performed by circulating the air inside the waterproof sheet 17, within the joint spacing 16, and other spaces within the waterproof structure. It's getting old.

As shown in FIGS. 2 and 4, a mounting plate 21 with a long hole 20 in the center is fixed to the right end of the front and rear sides of the bottom of the waterproof material 11 and protrudes to the right. When installing upward, the nails 22 are passed through the elongated holes 20 and fixed to the slab 14,
Even when the waterproofing material 11 expands and contracts, the elongated holes 20 prevent the waterproofing material 11 from being deformed or damaged by horizontal loads as much as possible. Further, the insert material 12 inside the waterproof material 11 may be cut and divided into a plurality of pieces internally so that it can be deformed to adapt to the unevenness of the mounting surface.

As shown in FIG. 4, within the joint spacing 16 of the waterproofing material 11, a horizontal flange portion 23b is provided protruding from the upper end of a groove-shaped cross-section portion 23a, such as a V-shape or U-shape, made of a metal plate or a resin plate. The joint gutter 23 is inserted, and the flange portion 23b is connected to the left and right waterproof materials 11.
It is tightly fixed to the upper end of the board by brazing or gluing. Further, a joint cover 24 having a trapezoidal chevron cross section 24a is provided above the joint gutter 23 so as to cover it, and flange portions 24b at both ends of the joint cover 24 are provided on both sides of the joint gutter 23 to provide left and right waterproofing. It is closely fixed to the upper surface of the material 11 by brazing or adhesion.

Due to the above structure, even if the waterproof material 11 expands and contracts and deforms from side to side, the groove-shaped cross section 23a of the joint gutter 23 opens and closes accordingly, and the upper joint cover 24
The chevron-shaped cross section 24a can open and close to absorb the above deformation. Therefore, the joint cover 24 is not limited to the illustrated cross-sectional shape, but may have an arc shape, a square shape, an inverted V shape, etc. except for the flange portion 24b, and if it is made of a stretchable material, the shape of the joint gutter 23 can be changed. It is also possible to use a tape-like material that is adhered directly onto the flange portion 23b.

Due to the above-mentioned joint structure, all the joints have a double structure, and even if the joint cover 24 is damaged or its adhesion is impaired, there is a joint gutter 23 below it, so problems such as water leakage can be avoided immediately.

Fig. 5 and Fig. 6 are both exploded perspective views showing an example of the double waterproof structure at the intersection of the above-mentioned joints. First, a notch 23C corresponding to the width of the joint interval 16 in the other direction is provided in the flange portions 23b on both sides of the joint gutter 23 in one direction (usually in the vertical direction). The other horizontal joint trough 23 is provided so as to butt against this joint trough 23 in a perpendicular direction from both sides, but in this case, the end of the V-shaped cross section 23a at the abutting end is at the joint interval 16.
In order to prevent rainwater, etc. from flowing in, the structure is as described below.

That is, at the ends of the V-shaped cross section 23a, folding folds 23d are provided in the vertical direction from the center to the left and right to form a V-shape, and triangular connecting pleats 23e are provided at the upper end thereof. Furthermore, a connecting cover 23f made of an equilateral triangle is provided at the upper ends of the connecting folds 23e and folded folds 23d, and an inner cover 23g that is bent into the groove-shaped cross section 23a is connected to the tip of the connecting cover 23f. ing. When assembling these, the end of the V-shaped section 23a of the horizontal joint trough 23 is accommodated in the notch 23c of the other joint trough 23 and abutted, and the lower surface of the connecting pleat 23e is connected to the other joint trough 23 at the abutted portion. At the same time, the lower surface of the inner cover 23g is brazed or bonded to the inner surface of the groove-shaped cross section 23a.

And the V of the joint gutter 23 combined in a cross shape
The letter-shaped cross section is accommodated in the intersection of the joints, and each flange portion 23b is fixed to the upper end of the waterproofing material 11 below by gluing or brazing as described above, and the joint cover 24 is fixed as shown in FIG. As shown by the imaginary line, one cover is placed over the intersection along the joint, and the other objective cover 24 has its left and right ends cut along the side shape of the joint cover, butted and glued together. It is sealed and fixed by caulking or brazing.

FIG. 7 shows a joint 23' used in another method for treating joint intersections, in which case it has the same cross section as the joint trough 23 and has a flange 2
3'b and the groove-shaped cross section 23a are each shaped perpendicular to each other, and are molded from a metal plate or resin, and accommodated in the intersection of the joints, and extend to the end of each waterproof material 11. It is overlapped with the end of the joint gutter and fixed by gluing or brazing. The joint cover 24 in this case may have the same structure as that shown in FIG.

This invention is constructed as described above, and since the waterproof material itself is a sealed container, even if the outer case on the front side is damaged, rainwater will not reach the base directly, and the bottom inside the outer case of the waterproof material The advantage is that even if the skin of an individual waterproofing material is damaged, water will not leak to other waterproofing materials or the underlying material. Furthermore, when such a situation occurs, the outer case bulges out more than others due to the influence of water intrusion, making it relatively easy to discover failures and repairing or replacing damaged parts. In particular, when creating a vacuum inside the exterior case, in addition to preventing internal condensation and improving the insulation effect, the entire waterproof material will naturally swell as atmospheric pressure builds up inside without waiting for the effects of water intrusion. Characteristics appear quickly and reliably.

In addition, when installing it on the roof, there is no need to glue it with adhesive, nail it in place with many nails, or hold it down from the top of the waterproof material, as in the past. There is also an advantage that the number of construction steps can be reduced, such as by simply attaching or fastening the mounting plate 21 and making it easy to replace the waterproofing material, which requires removal.

Furthermore, according to the joint treatment of the present invention, the joint itself also has a double structure, which has the provisional effect of preventing water leakage when the front cover is damaged, as described above, and is also effective against expansion and contraction fluctuations of the waterproof material. The joints themselves deform accordingly, which has an excellent effect of preventing damage to the joints.
