Description

[Detailed Description of the Invention] (Industrial field of application) For roof tile roofs, after filling the roof tile recesses with a backup material, an adhesive is applied to the entire protrusions of the base tile bars. Non-vulcanized rubber sheets are sequentially attached to a base, and the sheets attached in advance are superposed and joined to form a continuous waterproof coating layer of the non-vulcanized rubber sheet on the entire roof of the roofing tile roof. Is.

(Prior art) Conventionally, for roof tile roofs, the roof tile roofing method is used. Roof tile roofs are also roofed with steel sheets. Roof tiles are piled on roof tiles. Rehabilitation methods such as the method of installing a waterproof layer on a flat surface covered with a base plate after assembling wood have been implemented, but each has its own features and drawbacks.

(Problems to be Solved by the Invention) Problems to be solved by the present invention include the following.

Since the roof relining method removes the roof at the time of renovation, it costs a lot of money to remove dust and rain curing after removal, and it is impossible to use the inside of the building during renovation. .

In the method of stacking roof tiles on the roof tiles using a steel plate in the same way, the roof slab will increase in weight, which is structurally uncertain. In practice, the overlapping roofing method is used for roofs of small houses and the like, but it is the fact that it is not often used for roof slabs with a large area in order to prevent danger from the viewpoint of safety.

In addition, in the case of stacking thatched roof, it is easy to get an uncertain fit for the goby and the ridge, and it is also anxious about the waterproof aspect.

The method of assembling the tree on the upper surface of the existing purlin, then laying the base plate on the wooden board, and then installing the new waterproof layer on the smooth foundation is a large-scale renovation method, The biggest drawback is that the material and the construction cost for assembling the base plate and attaching the base plate to the wood are extremely expensive. Furthermore, the structural fit of the base and the end of the waterproof layer are complicated, which tends to result in waterproof defects.

(Means for Solving the Problem) According to the present invention, a roof bar roofing base having continuous unevenness is provided with a backup material in the recess of the goby, and then adhered to the iron plate base and the roof bar fixing to the roof base. After the agent is applied and dried, the non-vulcanized rubber sheet to which the adhesive has already been applied is adhered to the base and the convex portion of the roof tile goby portion 8 in sequence, and the end of the non-vulcanized rubber sheet is further attached. Part and the non-vulcanized rubber sheet previously attached to the base, the non-vulcanized rubber sheet is laminated and bonded with an adhesive using an adhesive, and the entire waterproof sheet is coated with a protective coating. The waterproofing method is characterized in that a continuous non-vulcanized rubber sheet waterproof coating layer is formed on the entire surface of the roof of the roofing tile roof.

In the renovated waterproofing method of the present invention, since a flexible non-vulcanized rubber sheet is directly laid on a tiled roofing roof substrate having continuous unevenness, a tile having a complicated structure is not specially deformed. The invention relates to a waterproofing method for directly attaching a non-vulcanized rubber sheet to a barbed roof, and is characterized in that its workability is remarkably improved and rain leakage can be prevented for many years after repair.

In the present invention, a backup material is attached to the gore concave portion of the roof of the roof tile to fill the space of the case portion, but a polyethylene foam sheet is appropriately cut as a backup material so as to absorb the movement of the iron plate. Those are preferable.

Next, after the adhesive is applied to the base surface and around the goby portion and to the surface of the non-vulcanized rubber sheet, the non-vulcanized rubber sheet is attached to the base when the drying time has elapsed and the open time has elapsed.

Then, with respect to the non-vulcanized rubber sheet pasted first, the sheets are superposed and joined, and this step is sequentially repeated to form a sheet waterproof layer, which is a waterproof method.

The non-vulcanized rubber sheet applied to the present invention is a Japanese Industrial Standard JI.
S A6008 “Synthetic polymer roofing”, non-vulcanized rubber sheet is suitable, and it was confirmed by the same survey that the property of the construction example has been aged for a stable waterproof layer. Is.

Further, it was confirmed that an adhesive obtained by combining and blending a butyl rubber-based rubber having a good water resistance and a chloroprene rubber-based rubber having a good initial adhesive strength was suitable as an adhesive applied to this method.

(Structure) An embodiment of the waterproof sheet construction method of the present invention will be described in detail with reference to the drawings.
On the other hand, after attaching the backup material 4 to the goby concave portion 7, the adhesive 2 is applied and dried on the iron plate underlayer 5 and the roof tile goby 8 fixed to the roof underlayer 11 and the adhesive 2 is already applied. The vulcanized rubber sheet 1 is sequentially attached to the base 5 and the convex portion 8A of the roof bar gore portion 8, and the end portion 1A of the sheet 1 and the non-vulcanized rubber sheet 1 previously attached to the base 5 are attached. Against this, the sheets are superposed and joined at the superposing section 3 by using the adhesive 2, and the entire waterproof layer of the sheet is protected and coated.
The waterproofing method is characterized in that 10 is applied to form a continuous non-vulcanized rubber sheet 1 waterproof coating layer on the entire surface of the roof with a roof of tile roof.

First, the iron plate base 5 serving as a base is subjected to brushing with a wire brush or the like to remove the floating material on the surface of the surface where the floating or choking phenomenon of the surface coating and the area where iron rust has occurred. In addition, as a base treatment, coating of anticorrosive paint or a damaged portion of the base iron plate 5 is treated as necessary.

As the backup material 4 applied to the concave portion 7 of the roof bar goby portion 8, a polyethylene foam sheet is made to have a width that is about 5.0 mm narrower than the width of the concave portion 7 of the goby portion 8, and the depth of the concave portion 7 of the goby portion 8 is set. However, it was confirmed that the backup material 4 having a size in which the thickness is increased by about 20 to 30% is suitable. The adhesive 2 is applied to the concave portion 8A of the goby portion 8, the open time is estimated, and the backup material 4 prepared previously is attached to the concave portion 7 of the goby portion 8.

Next, the adhesive 2 is applied to the entire surface of the roof substrate 11 and the goby portion 8.
The unvulcanized rubber sheet 1 having a width of about 530 to 580 mm and a thickness of 2.0 or 1.5 mm and the uncured rubber sheet 1 is aligned with the reference line at the corner of the corner. Stick it on the flat part of the base 5 so as not to entrap air.

Next, the sheet 1 is attached so that the sheet 1 is sufficiently aligned with the corner base 5 of the entry corner 8B of the goby portion 8, and further, the sheet 1 is carefully attached while the sheet 1 is placed along the goby portion 8.

After the sheet end portion 1A and the sheet 1 previously attached to the flat surface portion of the iron plate underlayer 5 are mutually bonded by using the adhesive 2, the flat portion of the underlayer 5 is joined. , The goby portion 8, the superposition joining portion 3, and the like are sufficiently rolled by using a rolling roller to bond the non-vulcanized rubber sheet 1 to the base 5.

A portion where three sheets 1 are superposed is particularly likely to be defective in terms of waterproofing. Therefore, in order to make up for the thickness difference of the sheet, a rain seal is applied to the inside and outside of the three-sheet overlapping portion by using an irregular seal ring material.

When the seat is completely stretched, the entire roof is inspected, and then the waterproof layer 10 is coated with protective paint 10 to finish.

In the roof of a tiled roof, it is necessary to provide sufficient rain protection for various types of accessories and to prevent the non-vulcanized rubber sheet from being peeled off by wind blowing from the eaves.

(Operation) In the waterproofing process according to the present invention, the shape of the backup material 4 used for the groove width of the recess 8A of the goby portion 8 of the roof tile roof is set to be about 5 mm narrower than the groove width. Since there are gaps on both sides and the height of the backup material is increased by 20 to 30% depending on the groove depth, after applying the adhesive 2 and drying it, when it is fitted into the goose recess 7 and attached. Workability is good, and because the backup material is slightly higher than the groove, a small space is created in the entry corner 8B of the goby groove, which cushions the expansion and contraction of the iron plate due to temperature and the movement of the roof slab due to wind. As a result, the effect that the waterproof layer is not directly affected is exhibited.

Next, from the flat portion of the iron plate base 5 to the entire convex portion 8A of the goby portion 8, a width of 530 to 580 mm and a thickness of 2.0 mm made of an unvulcanized rubber sheet.
Or, sticking a 1.5 mm tarpaulin can be used smoothly and its features are demonstrated. Furthermore, the non-vulcanized rubber sheet has good adhesive bondability between sheets, there is little variation in construction work, and it is easy to stick not only to the sheets but also to the substrate, so there is a gradient, so there is a gradient. It is the greatest feature of the non-vulcanized rubber sheet waterproof layer that the sheet waterproof method is applied to the renovated waterproof layer as in the present invention even in a roof with a tiled roof having many irregularities.

Until the present invention, a combination of various construction methods and various materials, the combination was studied, and many trial constructions were carried out, and as a result, the roof tile bar to which the non-vulcanized rubber sheet according to the present invention was applied was applied. It was established as a thatched roof repair method. That is, in the actual actual test building, in the trial and error until the present invention, the roof tile roof that applied the non-vulcanized rubber sheet, when the test building aged 10 years was investigated, the rain leak inside It was confirmed that the waterproofing was not performed, and when the appearance of the roof surface was further inspected in detail, it was confirmed that the waterproof sheet layer was sound and that the protective paint was slightly chalked. And since the non-vulcanized rubber sheet waterproof layer is lightweight, it can be repaired without impairing the durability of the roof slab, so even if it is judged that the use of the repair method is expanding, The present invention relates to a more effective invention.

(Example) Example 1 As an example, the general physical properties of a sheet material that can be used and the adhesion performance with a substrate will be illustrated.

1.General physical properties of non-vulcanized rubber sheet 2. Adhesive strength between coating base and sheet a. Vertical tensile adhesion B. Peel adhesion (Effects of the Invention) In existing roof tile roofs, the leakage of the rain often occurs due to loosening of the fittings of the gobs and the like due to the years after the completion of the building. Therefore, of the construction methods for preventing rain leakage, a suitable one was not found in the sheet waterproof construction method, but there are many irregularities, and in the present invention, a flexible non-vulcanized rubber is used for tile roof slabs with many roles. By applying a sheet, it is possible to prevent rain leakage for many years after repair by installing a rubber sheet waterproof layer on the entire roof of the roof with a roof tile.

In particular, the non-vulcanized rubber sheets are easily adhered to each other, have good adhesion to the base, and have good adhesion to the protective finish paint.
