Description

[Detailed Description of the Invention] The present invention relates to a heat insulation waterproofing method using a heat insulating material, and in particular, a heat insulating waterproofing method using a heat insulating material, in particular, the heat insulating material is laid down without adhering to the construction surface, and is divided into blocks by waterproof sheets, and the waterproof sheets are sequentially joined together. Regarding the waterproofing method, in detail, one ear of the waterproof sheet is held between the sides of the adjacent insulation material, and the end of this ear is fixed to the construction surface.
The present invention relates to a heat insulation waterproofing construction method in which the other edge of the waterproof sheet is joined to the waterproof sheet stacked on the adjacent heat insulating material without bonding.

Today, various insulation and waterproofing methods have been developed in order to reduce the weight of roof slabs. Among these methods, insulation materials such as plate-shaped polyethylene foam or polyurethane foam are laid on top of the roof slab using an adhesive. A fully adhesive method is well known in which a wide waterproof sheet is attached on top of the waterproof sheet using an adhesive.
However, since this method uses adhesive on the top and bottom surfaces of the insulation material, wrinkles are likely to occur in the waterproof sheet, the waterproof sheet is likely to swell due to the adhesive, and the adhesive may be unevenly applied. There are drawbacks such as the difficulty in uniformly adhering the waterproof sheet due to dry patches of the adhesive, and sophisticated construction techniques are required to avoid these drawbacks.

Therefore, in order to improve these shortcomings, the bar fastening method (Batten fast method), which does not use adhesive at all, was created. This construction method involves fixing a waterproof sheet spread over the insulation material to the insulation material using fixing members such as screws, rubber moldings, or presser rods, and then fixing the insulation material to the roof deck. This method covers the fixing member using a rubber stop or a wide sheet. This construction method does not use any adhesive, so it does not have the drawbacks of the above-mentioned full-surface adhesive construction method, but it still has the following drawbacks.
That is, since the waterproof sheet in the area where the fixing member is not present is not bonded to the heat insulating material, the waterproof sheet may be lifted from the heat insulating material due to wind pressure or other external stress. As a result, the fixed portion of the waterproof sheet is subjected to large stress and is easily damaged by the nails of the fixed member. Furthermore, since the portion where the fixing member is located protrudes from the surface, it is inevitable that the appearance will be poor, and there is also the problem that wrinkles in the waterproof sheet cannot be removed when they occur.

In view of the above-mentioned drawbacks of the conventional insulation and waterproofing method, the present invention aims to provide a new bar-holding construction method that improves these problems by firmly fixing the waterproof sheet loaded on the insulation material, and fixing the fixed part. It was invented for the purpose of improving the appearance of the tarpaulin sheet, preventing the occurrence of wrinkles on the tarpaulin sheet, and improving the appearance by preventing the fixing members from protruding from the surface of the tarpaulin sheet after installation, and its characteristics. This is because in the above-mentioned insulation and waterproofing construction method, the insulation material is placed on the construction surface without being glued, and the waterproof sheets are layered on top of the insulation material, dividing each block into blocks and joining the waterproof sheets together. As shown below, there are some points to be constructed.

In other words, a heat insulating material is placed on the construction surface without adhesion, a waterproof sheet is stacked on the surface without being glued, and one edge of this stacked waterproof sheet is folded along the side of the heat insulating material. At the same time, the tip of the ear part is L
Fold it into a shape and fix it to the construction surface, then use another insulation material with the same thickness as the above insulation material, and connect the folded part along the side of the insulation material of the waterproof sheet to that side surface and the side surface of the insulation material laid before it. Lay the waterproof sheet on the construction surface so as to cover the tips of the ears, then layer the waterproof sheet again without adhering to the surface, bend one of the ears in the same manner as above, and fix it to the construction surface. , After that, this process is repeated until the waterproof sheet is held between the sides of the insulation material and the end of the ear part is fixed to the construction surface, while the other ear part of the waterproof sheet is attached to the waterproof sheet on the surface of the adjacent insulation material. This is a construction method that involves joining via an adhesive member.

Hereinafter, the waterproofing method of the present invention will be explained in more detail with reference to the accompanying drawings. FIG. 1 is a plan view showing a state in which waterproof sheets of heat insulating material are laminated for each block, and FIG. 2 is a side view thereof.

First, a heat insulating material 1 is made of a plate-shaped body made of foam such as polystyrene, polyethylene, polyurethane, fiberboard, perlite, and a composite of these materials, with a width of 900 to 2400 mm and a thickness of 12 to 80 mm.
is laid on a horizontal or inclined construction surface 2,
In this case, the heat insulating material 1 is not bonded to the construction surface 2. And next, ethylene-propylene terpolymer,
A waterproof sheet 3 made of a vulcanized rubber sheet made of butyl rubber or a blend thereof is simply placed on the heat insulating material 1 without adhesive, and one edge 4 (approximately 50 mm or more) of the waterproof sheet 3 is It is bent to run along the side surface 5 of the heat insulating material without adhering, and the tip 6 of the ear part is further bent into an L shape and fixed to the construction surface 2. If the construction surface is concrete, an adhesive is used as a fixing means, but if the construction surface is water or steel, elongated metal or resin presser rods or rubber bars are used to ensure fast fixation in a short period of time. A fixing auxiliary member 7 made of a mold is placed on the ear tip 6, and a fixing member 8 such as a screw or nail is placed on top of the ear tip 6.
Fix it to the construction surface.

Next, another heat insulating material 1 having the same thickness as the above heat insulating material 7 is laid on the construction surface 2 so as to cover the tip 6 of the ear part of the waterproof sheet, and the ear part 4 of the waterproof sheet is placed between Hold it between sides 5. One of the ears 4 and the edge of the waterproof sheet 3 which is stacked on the adjacent heat insulating material 1 without being glued is placed along the side surface 5 of the heat insulating material and secured by the fixing member 7 in the same manner as described above. The waterproof sheet is fixed to the construction surface 2, and this process is repeated one after another, and the waterproof sheet is held on the side surface of the heat insulating material, and the tip of the ear part is fixed to the construction surface by the fixing member.

After the fixation is completed in this way, next, the waterproof sheet 3 and the adhesive member 10 are stacked on the surface of the adjacent heat insulating material, for example, a 50 to 100 mm wide portion of the other lug 9 of the waterproof sheet 3, For example, they are joined using naturally vulcanized adhesive tape. In this way, by dividing the insulation material into blocks using waterproof sheets and sequentially joining the waterproof sheets on the surface of the insulation material, the insulation material can be bonded to the construction surface and the waterproof sheet with adhesive. In order to firmly fix one ear of the waterproof sheet with a fixing member and join the other ear with an adjacent waterproof sheet,
The insulation is well retained by the tarpaulin.

In addition, in the case of the present invention, the case where one block of heat insulating material is one piece was explained as described above, but
Of course, the present invention is not limited to this,
It goes without saying that one block of heat insulating material may consist of two or more pieces.

Fig. 3 shows the case where one block of such insulation material is two sheets.One block is two sheets of insulation material 1 butted in the width direction, and the width corresponding to the width of this one block is shown. Use the waterproof sheet 3 that has. In this case as well, a predetermined construction surface can be obtained by fixing one ear tip 6 of the waterproof sheet to the construction surface using the fixing member 7 and joining the previous ear with the adjacent waterproof sheet 3. However, in this case, by using a wide tarpaulin,
This method has the advantage of shortening the construction time because the work of fixing and joining both ends of the waterproof sheet can be reduced.

FIG. 4 shows the construction mode at the beginning or end of each construction in the present invention, and although it is not particularly essential in the present invention, for the sake of explanation, in this illustrated example, the construction surface 2 stands up in the direction perpendicular to the construction surface 2. A construction method when a wall 11 is present is shown. That is, a wooden auxiliary member 12 is placed between the end insulation material 1 and the vertical wall 11, which have been laid by the construction method shown in FIGS. The sheet 3 is extended to the auxiliary member 12 and loaded. In this case, the end 13 of the tarpaulin is placed adjacent to the vertical wall 11. Next, in order to fix the waterproof sheet 3 to the auxiliary member 12, a fastening member 14 such as a screw or a nail is inserted into the auxiliary member 12 from above the waterproof sheet 3.

Thereafter, the ears 16 of the waterproof sheet 15 fixed to the vertical wall 11 are bonded to the waterproof sheet 3 located on the auxiliary member 12 via adhesive or adhesive tape. In this way, the construction of the insulation waterproofing method according to the present invention is started or completed.

As described above, the construction method of the present invention does not adhere each heat insulating material to the construction surface and the waterproof sheet, but instead fixes the tip of one ear of the waterproof sheet to the construction surface, and connects the other ear to the adjacent waterproof sheet. In addition to being able to firmly fix the tarpaulin sheet loaded on top of the insulation material, the waterproof sheet does not have any fixing members exposed on the surface, and almost no protrusion from the joint area. Since the waterproof sheet can be fixed without any installation, the appearance of the waterproof sheet after installation can be improved.

Since the insulation material is divided into blocks by a tarpaulin sheet, a narrow tarpaulin sheet can be used, which prevents wrinkles in the tarpaulin sheet, and each block is sealed by the tarpaulin sheet. As a result, even if water intrudes into one block of insulation, it will not infiltrate into an adjacent block.
