〔産業上の利用分野〕
この考案は、例えば陸屋根に防水シートを張設
してその上に押えモルタル層を形成する場合の、
押えモルタル層用目地材に関するものである。[Detailed description of the invention] [Industrial field of application] This invention is useful when, for example, a waterproof sheet is stretched over a flat roof and a retaining mortar layer is formed on it.
This invention relates to a joint material for holding mortar layers.
押えモルタル用を含むコンクリート用目地材

床面に所要の間隔をおき立設することで、打設し
たコンクリートの膨張収縮に順応して収縮膨張す
る。 The joint material for concrete, including the one for holding mortar, will be explained using FIG. 1 of the drawing of the present invention: a long joint material body 1 made of a soft foamed organic polymer, and a soft or hard organic polymer. By attaching the caps 2 to the joint material body 1 and standing them upright at the required intervals on the floor surface where concrete is to be poured, the expansion of the poured concrete is prevented. It contracts and expands in response to contraction.
又目地材本体１に装着したキヤツプ２は打設コ
ンクリートの層厚を一定にするための定規として
の機能と、モルタル打設後の目地材本体上部の損
傷を防止する機能を有する。 Further, the cap 2 attached to the joint body 1 has the function of a ruler to keep the layer thickness of poured concrete constant, and the function of preventing damage to the upper part of the joint body after mortar is placed.
しかしながら、陸屋根上でコンクリート（押え

に脹らみ湾曲して定規としての機能を失い床面へ
の直線状支持が困難になる。 However, when pouring concrete (holding mortar) on a flat roof, the joint material and caps are brought in in advance and placed on the floor.
If there is strong direct sunlight at that time, the side of the joint material that receives direct sunlight absorbs heat and expands, swells and curves in the direction of the sunlight, losing its function as a ruler and losing its linear support to the floor. It becomes difficult.
又径年変化して目地材が収縮するという問題も
ある。 There is also the problem that the joint material shrinks over time.
これを防止するためにキヤツプの天板部層内に
鉄板芯を入れる提案もあるが成形に困難性があ
り、且つ目地材を切断するのに手間がかかる。 In order to prevent this, there has been a proposal to insert an iron plate core into the top layer of the cap, but this is difficult to form and requires time and effort to cut the joint material.
ところで、実開昭54−116918号公報には、上記
キヤツプに、ポリアミド繊維、ポリエステル繊維

技術が開示されている。 By the way, Japanese Utility Model Application Publication No. 54-116918 discloses a technique of using an organic polymer material mixed with staple fibers such as polyamide fibers and polyester fibers in the cap.
しかしながら、その開示技術は、上記有機高分

い。 Furthermore, the mixing of short fibers in the disclosed technology is intended to strengthen the cap and improve its adhesion to mortar, so it does not effectively solve the problem of shrinkage and deformation caused by heat and sunlight irradiation. .
この考案は、以上の点に留意し、耐オゾン性に

In order to solve the above problems, this invention consists of a joint main body made of a soft foamed organic polymer material and a cap made of a soft or hard organic polymer material attached to the joint main body. In the well-known joint material for concrete described in the published gazette, the organic polymer material of the cap is vinyl chloride resin, polyethylene, or polypropylene, and glass fiber is mixed therein.

The joint material according to this invention configured in this way is
Since the cap is made of an ozone-resistant organic polymer material such as vinyl chloride, it is less susceptible to ozone deterioration. On the other hand, vinyl chloride, etc., has a higher rate of shrinkage and change due to heat and sunlight irradiation than synthetic rubber, but since it contains inorganic glass fibers that hardly shrink or change, due to the inclusion of vinyl chloride, the rate of shrinkage and change due to heat and sunlight irradiation is higher. Shrinkage and changes in organic polymer materials such as vinyl chloride due to temperature changes are minimized, and this reduced shrinkage also makes them less likely to deform.
