Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of constructing a waterproof sheet, and more particularly to a method of constructing a structure for covering the surface of a building frame with a plurality of waterproof sheets. Such a construction method is applied, for example, to waterproofing a building or structure.

[Conventional technology]

Conventionally, waterproofing of buildings or structures has been carried out by pasting multiple waterproof sheets with appropriate unit dimensions onto the surface of the building using an adhesive, and by overlapping the adjacent edges of each waterproof sheet. This was done by gluing.

[Problem that the invention seeks to solve]

However, in conventional waterproofing construction as described above, the waterproof sheet cannot be bonded unless the building block is sufficiently dry, and sufficient adhesive strength may not be obtained depending on weather conditions such as temperature, so the construction period may be delayed. There is a problem in that the weather is affected by the weather. In addition, in conventional waterproofing construction as described above, the waterproof sheet has a uniform thickness over the entire surface, so the thickness at these joints is almost twice that of other parts and swells, resulting in Separation is likely to occur at the joint, and furthermore, the raised joint may impede the flow of rainwater, create puddles, and promote rain leakage.

[Failure to solve the problem]

According to the present invention, in order to solve the above-mentioned problems of the prior art, the edges of the joint have ears of the yakuri no dam, and the ears of the yakuri can be melted and bonded to each other. A waterproof sheet is placed on the surface of the building structure, and a base plate that can be melt-bonded to the ears and has needle holes is superimposed on the ears of the waterproof sheet, and nails are driven through the needle holes in the base plate. By this, the above-mentioned waterproof sheet is fixed to the fan body,
After that, the ears of the M-adhesive waterproof sheet are superimposed on the ears of the waterproof sheet, and then the ears of the two waterproof sheets and the base plate are joined to each other by melt adhesion. A method of constructing a tarpaulin sheet is provided.

〔Example〕

Hereinafter, specific examples of the construction method of the present invention will be described with reference to the drawings.

FIGS. 1(1) to 1(d) are cross-sectional views showing steps of an embodiment of the construction method of the present invention.

First, as shown in FIG. 1 (1), a waterproof sheet 4 is placed on the surface of a frame 2 made of concrete or the like.

The waterproof sheet 4 has a shape as shown in FIG.

That is, the waterproof sheet 4 is joined to another waterproof sheet having a similar configuration by joining their edges together. For this reason, the waterproof sheet 4 has an ear part 8 on the lower surface side for playing with at one edge part 6, and has an ear part 8 on the lower surface side for playing with each other at one end edge part 6, and has an ear part on the lower surface side for playing with each other at an end edge part 10 on the opposite side to the edge part 6. It has an ear portion 12 on the upper surface side. The tarpaulin sheet 4 is different from 2
The lug portion 6 on the lower surface side and the lug portion 12 on the upper surface side of the two waterproof sheets are configured to be bath-fused and bonded. Examples of such a waterproof sheet 4 include those made of materials such as rubber asphalt and vinyl chloride resin.

Next, as shown in FIG. 1(b), a long pedestal board 4 is placed on the ear part 8 on the lower surface side of the waterproof sheet 4 along the length direction of the ear part.

The base plate 14 has a shape and structure as shown in FIG. That is, the width of the base plate 14 is equal to the width of the waterproof sheet 4.
It has an appropriate length and is smaller than the width of the ear portions 8 and 12 of. Further, the base plate is a plate-like body having a predetermined strength, and is configured so that it can be melt-bonded to the ears 8 and 12, which are the joint parts of the waterproof sheet 4. Such a pedestal plate 14 is made by coating both sides of a plate-shaped body 16 made of iron or the like with a layer 18 made of the same material as the waterproof sheet ears 8 and 12 (for example, rubber asphalt, vinyl chloride resin, etc.). Examples include: Further, the base plate 14 is provided with a needle hole 20 for driving a nail through the plate surface. The needle holes are provided at appropriate intervals along the length of the base plate 14.

Next, as shown in FIG. 1(c), a nail 22 is driven from above through the needle hole 20 of the base plate 14, thereby fixing the base plate 14 and the waterproof sheet 4 onto the surface of the frame 2. It will be done. A waterproof sheet 4' having the same structure as the waterproof sheet is placed adjacent to the fixed waterproof sheet 4.

This arrangement is such that the upper ear part 12' of the waterproof sheet 4' is overlapped with the fixed lower ear part 8 of the waterproof sheet 4.

Next, as shown in FIG. 1(d), the lower ear part 8 of the waterproof sheet 4, the base plate 14, and the upper ear part 12 of the waterproof sheet 4'
′ are melted and bonded by heating or the like.

Thus, the head of the nail 22 and the base plate 14 are covered with the waterproof sheet 4.
' is completely covered by the upper ear 12', and the upper ear 12'
Since 2' is melted, the watertightness of the joint and the smoothness of the upper surface of the waterproof sheet are sufficiently good.

A large number of waterproof sheets can be fixed onto the surface of the building frame by repeatedly performing the above-described joining of the waterproof sheets at each joining portion. Further, although the above embodiment shows only the joining of two opposing edges of a waterproof sheet, it is also possible to join other two opposing edges in the same manner, and in this way, a large number of waterproof sheets can be bonded. Fixation can be performed by arranging the sheets two-dimensionally.

In the above embodiment, the nailing interval is, for example, 50 to 15
Approximately 0.01 mm, for example, 1100 mm (spacing).In addition, it is preferable that the nailing spacing be relatively narrow, for example, 20 to 30 C1l, at a location near the end of the pedestal board.

〔Effect of the invention〕

According to the method of the present invention as described above, construction can be carried out with sufficient adhesion strength even when the building frame is in a somewhat wet state, so that the construction period can be significantly shortened regardless of the weather. Furthermore, according to the method of the present invention, the base plate is used during nailing, so even if the nailing gap is large, the sheet can be completely fixed.
Furthermore, since the waterproof sheet can be fixed evenly over the entire joint between the joints, it is possible to prevent damage to the waterproof sheet due to stress concentration occurring only at the nailing part due to external forces such as wind pressure or movement of the building frame. In addition, in the method of the present invention, since the waterproof sheet is not brought into close contact with the building frame as a whole, blistering can be easily prevented by providing a small number of vent holes, and damage to the waterproof sheet due to localized blistering can therefore be prevented. Furthermore, even if the frame is cracked, the waterproof sheet will not be affected by it.
