Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a laminate for a ridge tile fixed structural material.

More specifically, it is easy to install, does not collapse due to vibrations, does not leak, and does not soften even when exposed to rainwater.
This invention relates to a laminate suitable for use as a fixed structure material for ridge tiles that can withstand long-term use.

[Conventional technology]

There is a part called the ridge tile at the top of the roof made of Japanese tiles. The ridge tile has a mourning structure, with several layers of split roof tiles and a round roof tile on top. Conventional ridge tiles are made by packing plaster, clay, etc. between the split tiles or between the split tiles and the crown tile, and use the plaster or clay as a binder to create the split tiles or crown tiles. It has a structure in which tiles are fixed, and the split tiles and crown tiles are connected and fixed using copper wire or the like.

[Problem to be solved by the invention]

Conventional construction methods for fixing ridge tiles use plaster, plaster, etc., and the tiles are connected and fixed using copper wire, which has the drawback of being complicated and prone to individual differences in construction. Furthermore, since plaster and clay are used as fixing materials for roof tiles, over a long period of time, the plaster and clay will weather and lose their adhesive strength, becoming brittle and prone to cracking due to small vibrations. Sara K has the disadvantage that when it is subjected to vibrations caused by typhoons or the ground, the plaster and plastering parts easily crack, causing rain leaks and the ridge tiles collapsing. In addition, when rainwater etc. seeps into the plaster and plastering areas, the plaster and plastering become soft.
As a result, the ridge tile may lose its shape, and if the stucco or plastered area freezes due to winter construction or winter rainwater, the ridge tile becomes extremely brittle after drying. There are also problems such as difficulty in construction.

The present invention is easy to construct, there are no individual differences in construction, there is no need to worry about the adhesive strength decreasing due to weathering or freezing, and the present invention does not collapse even when subjected to vibrations caused by typhoons or earthquakes. The purpose of the present invention is to provide a laminate suitable for use as a ridge tile fixing structural material that does not soften even when wet with rainwater.

[Means to solve the problem]

The present invention has the following configuration.

(1) A laminate formed by laminating a thermoplastic resin and one or more types of nonwoven fabric, woven fabric, or knitted fabric, the laminate comprising six layers of the laminate.
The amount of deformation at 5°C is less than losm, the flexural modulus is 10
．． ○○Okg f A laminate for ridge tile fixed structural material having a size of 7 cm2 or more and a thickness of 1 to 5 cm.

(2) A laminate consisting of a thin metal plate and a thermoplastic resin, the laminate having a deformation amount of 10 at 65°C.
less than m, flexural modulus is 10,000 kgf/crnt
The above is a laminate for a ridge tile fixed structure material having a thickness of 1 to 5 mm.

(3) A laminate in which a thin metal plate is further laminated on the thermoplastic resin side of a laminate in which a thermoplastic resin and one or more types of nonwoven fabric, woven fabric, or knitted fabric are laminated, and A laminate for a ridge tile fixed structure material having a deformation amount of less than 10 degrees Celsius, a bending elastic modulus of 10,000 kgf/α2 or more, and a thickness of 1 to 5 m.

The thermoplastic resin used in the ridge tile fixing structural material laminate of the present invention includes crystalline propylene homopolymer, propylene containing 70 weight or more of a propylene component, and α-olefins other than propylene (ethylene, butene-1, pentene-1, etc.). 1. Crystalline copolymers of hexene-11 (heptene-1, octene-1, decene-1) with mm or more, polyolefin resins such as high-density polyethylene, polyolefin resins such as unsaturated carboxylic acids or derivatives thereof (e.g. acrylic modified polyolefin resin modified with acid, methacrylic acid, maleic anhydride, etc.), polyvinyl chloride resin, polystyrene resin, acrylonitrile-butadiene-styrene copolymer resin, acrylonitrile-styrene copolymer resin, polycarbonate resin, polyamide resin, heat Examples include plastic polyester resins and mixtures of two or more thereof.

Examples of the metal thin plate used in the ridge tile fixed structural material laminate of the present invention include an aluminum plate, iron plate, stainless steel plate, etc., and the thickness of the metal thin plate is 50 to 300 mm.
Microns are preferred. Also, from the viewpoint of rust resistance, aluminum plates and stainless steel plates are preferable.

The nonwoven fabrics, woven fabrics, and knitted fabrics used in the ridge tile fixed structure laminate of the present invention include natural fibers such as cotton yarn and hemp yarn, synthetic fibers such as polyester fibers and polyamide fibers, carbon fibers,
Examples include nonwoven fabrics, woven fabrics, and knitted fabrics using fibers such as metal fibers and mixtures thereof, and the basis weight of the nonwoven fabrics, woven fabrics, and knitted fabrics is not particularly limited, but is 30 to 50.
Of/TrL1 is preferred.

The ridge tile fixed structural material laminate of the present invention has a deformation amount at a temperature of 65°C of less than 10 W, preferably 5 n+ or less, and a flexural modulus of 10,000 kgf/an2 or more, preferably 1 O,000 kgf/ca2~ 100 +

ni9j' /-~50 + OOOlcgf /aL"
The thickness thereof is 6.1 to 5 m, preferably 1.3 to 4 m.

If a laminate with a deformation amount of 10 m or more is used, the resulting ridge tile fixing structure material is likely to undergo deformation during the summer season, which is undesirable, and the bending elastic modulus is 10.00 OA47f.
It is not preferable to use a laminate with less than 100.0001ogf/cam because the resulting structural material will deform during long-term use or during periods of high temperature.
It is necessary to be careful because the workability of the resulting ridge tile fixing structure material will deteriorate if a laminate exceeding Furthermore, if the thickness of the laminate is less than 111II, it will be difficult to firmly fix the split tiles to the obtained ridge tile fixing structure material with screws, and if the thickness exceeds 5. When ridge tiles are introduced as structural materials, a gap of several tiles above and below occurs at the tip of the ridge tiles, making it easy for rainwater to infiltrate, and when there is a sudden change in temperature, the structural materials become wavy and curly. This is not preferable because it causes problems such as smearing, and also deteriorates the cuttability of the structural material during construction.

The laminate for a ridge tile fixed structural material of the present invention can be obtained, for example, by the following method.

That is, thermoplastic resin and nonwoven fabric, woven fabric, or knitted fabric.
A laminate consisting of a thermoplastic resin sheet is prepared in advance, the sheet is reheated to a temperature higher than the softening point of the thermoplastic resin, and then the heated sheet is combined with a nonwoven fabric, woven fabric, or knitted fabric. 3 to 50 kg f
It is obtained by pressing at a pressure of about /an@. At this time, several layers of the heated sheet and nonwoven fabric, woven fabric, or knitted fabric may be alternately stacked and pressed to form a laminate consisting of several layers. A laminate in which a thermoplastic resin and a metal thin plate are laminated, or a laminate in which a metal is further laminated on the thermoplastic resin side of a laminate in which a thermoplastic resin and one or more types of nonwoven fabric, woven fabric, or knitted material are laminated can be produced by the above-mentioned method. However, in this case, K can be obtained by preheating the thin metal plate to about 100 to 250°C (preferably, and adding an unsaturated carboxylic acid or its derivative to the side of the metal plate to be laminated). It is preferable to interpose a modified resin layer.

Another method is to produce a thermoplastic resin sheet using a calendar method or an extrusion method using a T-die.
Woven or knitted fabrics can also be laminated to form a laminate.

The laminate of the present invention can be produced by preparing a predetermined laminate in advance and then using the laminate to form a ridge tile fixing structural material having a predetermined structure, or by simultaneously performing lamination and molding of the ridge tile fixing structural material. It also includes a laminate formed into a ridge tile fixed structural material consisting of a laminate of.

The thermoplastic resin used in the ridge tile fixing structural material laminate of the present invention includes various fillers such as calcium carbonate, talc, mica, clay, wood flour, and rice husk powder, weathering agents, coloring agents, and oxidizing agents. Inhibitors, lubricants such as metal soaps, plasticizers, various rubbers, and the like may be used within the range that does not impair the purpose of the present invention.

An example of a ridge tile fixing structure material using the laminate of the present invention is shown in FIG. As shown in FIG. 2, these are assembled by stacking them in several stages. At this time, a structural material is used in which the length of the wing part of the upper structural material, that is, the blade length, is shorter than that of the lower structural material. Next, the split tile is placed on the wing portion of the structural member, and the split tile is fixed to the wing portion of the structural member using screws or the like. A crown tile is placed and fixed at the top.

Such a structural material can be manufactured, for example, by the following method.

That is, the ridge tile fixed structural material laminate of the present invention is heated above the softening point of the thermoplastic resin constituting the laminate, and then press-molded in a mold having a predetermined shape of the structural material. It can be obtained by press molding in a machine at a pressure of about 3 to 50 f/cR2.

Alternatively, a sheet of thermoplastic resin is prepared in advance, this sheet is reheated to a temperature higher than the softening point of the thermoplastic resin, and then the heated sheet and nonwoven fabric, woven fabric, or knitted fabric are superimposed or formed into several layers. These are stacked together and press-molded at a pressure of about 3 to 50 phantom f/crn2 using a press molding machine equipped with a mold having the shape of the predetermined structural material, thereby simultaneously laminating and forming the structural material. You can get it even if you are busy. Even when thin metal plates are used, lamination and forming of the structural material can be performed simultaneously, similar to the method described above.
