Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an improvement in the waterproofing repair method for roofs with roofs, and more specifically, to waterproof the roofs of roofs with simple and easy workability. Concerning methods for refurbishing.

[Conventional technology]

Conventionally, the main methods used for waterproofing repair methods for roofs such as flat roofs have been the sheet waterproofing method, in which a sheet-like waterproofing material is laid over the repaired area, or the coating film waterproofing method, in which a resin waterproofing material is applied. In some cases, repairs are also carried out by applying paint with a high solidity content to prevent rust.

However, in the case of a Kawara-bo roof, the long bar-shaped protrusion called a Shikawara-bo, which is different from a flat roof, is 300 to 500 fi.
Since it has a unique structure provided at intervals, there are various difficulties in constructing the straw bar portion using the conventional construction method described above.

In other words, in the case of construction using the sheet waterproofing method, there is a problem in that the work of laying the sheet on the Kawarabō part is very troublesome and the workability and construction performance are poor. Not only is it difficult to form a homogeneous waterproof coating because of uneven coating, but it is also recommended to use cloth or other reinforcement to prevent uneven coating when applying thick coatings or to increase the durability of the coating. However, like the sheet waterproofing method described above, it has the disadvantage that the work is very complicated. Furthermore, waterproofing with paint has a temporary effect and is not suitable for waterproofing renovation work that requires durability.

[Problem that the invention seeks to solve]

In this way, there is still room for improvement in terms of workability and waterproofing performance in the waterproofing of Kawara-bo roofs using conventional construction methods, especially in connection with the construction of Kawara-bo roofs. There is a strong need for the emergence of

The present invention has been made against the above technical background, and its purpose is to provide a new and easy-to-use method for waterproofing roofs, especially roofs, with good workability. The goal is to provide a method. Another object of the present invention is to provide a novel waterproofing repair method capable of imparting durable and excellent waterproof performance to the straw rod portion of a straw rod roof.

[Means for solving problems]

The above object is to fit an elongated molded member made of a flexible and waterproof material with an inverted groove cross section to the straw rod of a roof roof through the groove, and to fit the long molded member made of a flexible and waterproof material to the straw rod of the roof, and to This is achieved by a method for repairing a Kawara-rod part in waterproofing renovation of a Kawara-rod roof, characterized in that the lower edge is sealed with a waterproof material.

The molded member used in the present invention for waterproofing the Kawara-bar part is:
It is a long molded product whose cross section has an inverted groove shape as shown in FIG. 2, for example. Materials include synthetic rubbers such as styrene-butadiene rubber, chloroprene rubber, butyl rubber, and ethylene-propylene rubber, natural rubber, and synthetic resins such as polyethylene, polypropylene, and polyvinyl chloride, which are flexible and waterproof. Among them, it is particularly preferable to use olefin materials from the viewpoint of weather resistance, toughness, etc.

Regarding the dimensions of the groove in the molded member, it is only necessary that the groove can be fitted into the Kawara rod, and there are no particular restrictions on its depth, width, etc., but generally and preferably the entire protrusion of the Kawara rod (top part The depth and width that can cover the area (from the base to the base) are used. Also, regarding the cross-sectional shape of the groove,
Rectangle [Figure 2 (at).

Inverted trapezoid [Figure 2 (bl) It may be circular, oval, etc., and is not particularly limited, but for example, it may be tapered toward the lower end like the inverted trapezoid shown in Figure 2 (bl K). When the molded member is fitted into the filler rod, the molded member clamps and fixes the filler rod in the narrowed portion due to its own flexibility and elasticity. This has the advantage that subsequent fixing work or sealing work is difficult and easy.

In addition, if the molded member is provided with an outward-facing flange-like edge (width of about 30 to 150 fi) at the lower end of the inverted groove-shaped leg as shown in Figure 3, it is possible to fix the molded member to the roof. etc., since the brim-shaped edge and the base plate of the roof (the flat surface between the kawara bars) need only be bonded between one plane, the work is not only a cylindrical case, but also a molded part. It has the advantage that the lower edge can be easily sealed and the waterproofness is improved. Therefore, molded parts with flanged edges are most preferably used in the method of the invention.

The thickness of each part of the molded member is not particularly limited, but 1
From the viewpoint of strength, durability, etc., it is desirable that the thickness be 1 dragon or more, and particularly preferably in the range of 3^5n. In addition, the length of the molded material is the same as or longer than the total length of the Kawarabo, and if it is cut to the appropriate size to match the repaired part at the time of construction, the work will be easier. This is preferable because it is easy.

Hereinafter, the waterproofing repair method of the present invention will be explained based on FIG. 1, which is an example of construction in the case where the elongated molded member has a brim-like edge at the lower end of its leg.

First, a long molded member (1) cut into appropriate dimensions according to the repaired area is cut into four parts (2) f.
Insert K so that it covers the Kawara bar part.

In this case, if the cross-sectional shape of the molded member (1) before construction is an inverted trapezoid as shown in Figure 3, it can be fixed to some extent only by the gripping force based on the inserted part, but generally speaking will be fixed to the roof using adhesive. In Figure 1, the collar-shaped edge (1a) of the molded member
is attached to the base plate (6) of the Kawara-rod roof, but if a molded member without a brim-like edge is used, it may be bonded to the side surface of the Kawara-rod, for example. As the adhesive (5), any adhesive that is normally used for sheet waterproofing can be used, but it is particularly preferable to use double-sided adhesive tape because of its good workability. In addition, when the molded part is fitted into the Kawara rod.

If there is a significant gap between them, it may be necessary to fill them with a back-up material such as sponge and then secure them in place.

Once the molded member has been fixed, the first step is to seal the lower end edges of both legs of the molded member (the flap-like edges (la) in Figure 1) and the longitudinal end with a waterproof material, and then seal the edges of the molded member with a waterproof material. Prevent water leakage. To seal the lower edges of both legs, as shown in Figure 1, a sheet-like waterproof material (for example, a rubber sheet) (3) is folded over the brim-like edge of the molded member, and the periphery of the sheet-like waterproof material is sealed. In addition to the method of sealing with plastic resin (4),
It is also possible to use a method in which the periphery of the brim-like edge of the molded member is simply sealed between it and the base plate of the roof using a sealing resin, without using the sheet-like waterproofing material.

The former type of sealing is particularly effective when repairing a Kawara-bo roof using the sheet waterproofing method. By applying a normal sheet-like waterproofing material to the flat part between them and treating the long edges of the sheet-like waterproofing material as shown in Figure 1, the kawara rod part and the base plate part can be waterproofed at once. Can be renovated. In addition, according to this method, the sheet-like waterproofing material can be laid and bonded only on a flat surface, so it is not necessary to install and adhere the sheet-like waterproofing material to the flat surface. Workability in sheet waterproofing is significantly improved without requiring complicated treatment and long time for construction. Note that depending on the shape of the molded members, it may be necessary to geoind the molded members together, but in this case, they may be butted together and the butt portions may be sealed with a sealing resin.

Sealing of the longitudinal ends (eaves, etc.) of a long molded member can generally be done in the same way as for the lower edge of the molded member described above, but sealing between the molded member and the straw bar If a relatively large gap exists, it is desirable to embed a rubber sponge or the like in the gap and then perform a sealing process.

〔Effect of the invention〕

According to the method of the present invention, the waterproof repair of the straw bar part of a straw roof roof, which has been extremely complicated and difficult in the past, can be carried out by a simple means of fitting a long molded member into the part and sealing the periphery. It is possible to complete the renovation, and even if you are repairing only the Kawara-bo roof, or the entire surface of the Kawara-bo roof, all that is left is to repair only the flat part between the Kawara-bo. Since the construction is simple, the construction period is greatly shortened compared to, for example, conventional sheet waterproofing.

Furthermore, if the molded member is subjected to surface treatment (painting, etc.) in advance, the surface treatment of the construction method can be performed only on the flat portion, making it possible to further simplify the process.

In addition to the above-mentioned good workability and construction efficiency, the method of the present invention makes it possible to impart homogeneous and durable waterproofing performance to the Kawara-bar roof. This is an extremely useful method for repairing the Kawara-bar part in waterproofing repairs.
