〔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
してその上面にモルタル層を形成する場合のモル
タル層用目地材用キヤツプに関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cap for a joint material for a mortar layer when, for example, a waterproof sheet is stretched over a flat roof and a mortar layer is formed on the upper surface thereof.
目地材としては本考案の図面第１図に示すよう
にスポンジのようにモルタルの膨張収縮に順応し
て収縮膨張する素材で縦断面長方形の長尺体から
なる目地材１が一般に使用されている。
As shown in Fig. 1 of the drawings of the present invention, joint material 1 is generally used as a joint material, which is made of a long body with a rectangular vertical cross section and is made of a material that contracts and expands like a sponge according to the expansion and contraction of mortar. .
上記目地材はモルタル層厚を一定にする定規の
機能を発揮させるために、頂部にキヤツプ２を装
着し、このキヤツプの頂面が定規の役目を兼ね、
且つ目地材１を保護する。 In order to perform the function of a ruler to keep the thickness of the mortar layer constant, the above joint material is equipped with a cap 2 on the top, and the top surface of this cap also serves as a ruler.
Moreover, the joint material 1 is protected.
目地材用キヤツプ２は軟質又は半硬質の有機高
分子物の長尺成形品からなり、縦断面下向き
「コ」字形を呈し、左右両側板部３の下縁には目
地材１に喰い込むための対向内側に向く爪縁４
と、モルタル層に入り込んでキヤツプの浮上がり
を防止するための対向外側に向く鍔縁５がそれぞ
れ連成してある。 The cap 2 for joint material is made of a long molded product of a soft or semi-hard organic polymer, and has a downward "U" shape in vertical section, and is attached to the lower edges of the left and right side plate parts 3 to be inserted into the joint material 1. Nail edge 4 facing inward opposite to
and opposing outward facing flange edges 5 for penetrating into the mortar layer and preventing the cap from lifting up.
ところでキヤツプはその素材の性質から経年す
るに従つて収縮することを免れず、収縮すると隣
接する両キヤツプ間に隙間を生じることになつて
好ましくない。 However, due to the nature of the material of the cap, it is inevitable that the cap will shrink over time, and when it shrinks, a gap will be created between the two adjacent caps, which is undesirable.
そこでこの考案の目的は、モルタル層成形後は
収縮が阻止される目地材用キヤツプを提供するこ
とにある。 Therefore, the object of this invention is to provide a joint material cap that is prevented from shrinking after the mortar layer is formed.
上記の問題点を解決するために、この考案はキ
ヤツプの左右両側板部の対向外側に向く鍔縁は、
所要間隔毎に根元から切除した切欠部を設けた目
地材用キヤツプとしたものである。
In order to solve the above-mentioned problems, this invention has been developed so that the opposing outward facing edges of the left and right side plates of the cap are
This is a joint material cap with notches cut out from the root at required intervals.
図において、６は鍔部５の所要間隔毎に根元か
ら切除して形成された切欠部である。 In the figure, reference numeral 6 denotes notches formed by cutting out the base of the flange 5 at required intervals.
なお、鍔縁５の形成はキヤツプ側板部の下縁に
限定せず中途部に設けることもできる。 Note that the formation of the flange edge 5 is not limited to the lower edge of the cap side plate portion, but may be provided in the middle.
この考案の目地材用キヤツプとしたことによ
り、以下に述べるような効果がある。
The joint material cap of this invention has the following effects.
この目地材用キヤツプは、打設したモルタル層
に入り込む鍔縁の所要間隔毎に根元から切除した
切欠部をそなえているので、この切欠部にモルタ
ル層が入り込んで硬化し、従つてキヤツプが長さ
方向に収縮しようとしても分割された鍔縁各片が
モルタル層にそれぞれ捕捉されているので収縮が
不能となり、長期にわたり隣接する各キヤツプ間
に収縮に起因する隙間が生じることがない。 This cap for joint material has notches cut out from the root at the required intervals of the flange edge that enters the poured mortar layer, so the mortar layer enters the notches and hardens, resulting in a long cap. Even if an attempt is made to shrink in the transverse direction, each divided piece of the flange edge is captured by the mortar layer, making it impossible to shrink, and no gaps will be created between adjacent caps over a long period of time due to shrinkage.
