区画分離するための目地材の改良に関するものである。[Detailed description of the device] This device maintains a required spacing on the slab concrete to prevent expansion and contraction of the finishing mortar when pouring finishing mortar onto the slab concrete, such as on the floor of a flat roof of a building. This invention relates to the improvement of joint materials that are arranged vertically and horizontally to separate finishing mortar into sections.
従来一般にこの種目地材は断面長方形の帯状長尺体が用
いられている。Conventionally, this type of material has generally been a belt-like elongated body with a rectangular cross section.
又この種目地材は仕上げモルタルの膨張収縮に順応させ
るために中空としであるものもある。In some cases, this joint filler is hollow to accommodate the expansion and contraction of the finishing mortar.
ところが前記仕上げモルタルが膨張収縮し、或はモルタ
ル上面に部分的に外力が加わると目地材が浮上ることが
あり、浮上ると目地材が破損し、且つ破損に伴う種々の
事故が発生する。However, when the finished mortar expands and contracts, or when an external force is partially applied to the top surface of the mortar, the joint material may float, and when it floats, the joint material is damaged, and various accidents occur due to the damage.
この考案はコンクリート目地材の上記従来の欠点を解決
したもので、その目的とするところは経年するも浮上る
おそれなき目地材を提供するにある。This invention solves the above-mentioned drawbacks of conventional concrete joint materials, and its purpose is to provide a joint material that will not float up over time.
又この考案の他の目的とするところは、モルタルの膨張
収縮に順応する大なるクッション性をそなえる目地材を
提供するにある。Another object of this invention is to provide a joint material that has great cushioning properties that accommodate the expansion and contraction of mortar.
この考案の更に他の目的とするところは、高さを高低可
変とし現場で簡単に高さを調整し得る目地材を提供する
にある。A further object of this invention is to provide a joint material whose height is variable and whose height can be easily adjusted on site.
以下この考案の構成を添付図面に基いて説明すれば、Ａ
はコンクリート目地材であり、この目地材は長尺円筒１
を複数個並列連結した帯状長尺体である。The configuration of this invention will be explained below based on the attached drawings.
is a concrete joint material, and this joint material is a long cylinder 1
It is a long belt-like body made by connecting multiple pieces in parallel.
長尺円筒１はその周側−面側に軸方向筋状の切欠開口部
２が形成してあり、又周側他面側には隣接する長尺円筒
の軸方向筋状の切欠開口部に嵌入し抜止めとなる断面膨
頭リブ３が形成しである。The elongated cylinder 1 has an axially streaky notch opening 2 formed on its circumferential side and the surface side, and an axially streaky notch opening 2 of the adjacent long cylinder on the other circumferential side. A rib 3 with an enlarged cross section is formed to fit in and prevent it from coming out.
長尺円筒１を所要数並列連結した帯状体の一側縁（下縁
）には基板４が連結され、又前記帯状体の他側縁（上縁
）には外面側（上面）が平らな頂部部材５が連結される
。A substrate 4 is connected to one side edge (lower edge) of a band-shaped body in which a required number of long cylinders 1 are connected in parallel, and a substrate 4 is connected to the other side edge (upper edge) of the band-shaped body with a flat outer surface (top surface). The top member 5 is connected.
基板４並びに頂部部材５には筋状切欠開口部２ａをそな
える円筒状部１ａ、又は断面膨頭リブ３ａの何れか一方
が形成されている。The substrate 4 and the top member 5 are formed with either a cylindrical portion 1a having a striped notch opening 2a or a rib 3a with a swollen cross section.

両面の、各円筒の連結部に形成される横方向凹条に入り
込み硬化するので、目地材が不用意に抜ける（浮上る）
おそれがないという効果がある。This idea has the structure described above, and this joint material is made by connecting a plurality of long cylinders in parallel, and the connection is made by connecting an axially striped notch opening and a notch opening of an adjacent cylinder. Since it is a joint of ribs with expanded cross-sections that fit in and prevent them from coming out, by placing the mortar 7 in an upright position on the concrete slab 6, the mortar is applied to the joints of each cylinder on both sides of the joint material. The joint material enters the horizontal grooves formed on the surface and hardens, causing the joint material to come off (float) inadvertently.
The effect is that there is no fear.
又この目地材は各円筒を連結したものであるから、打設
すべきモルタルの高さに合わせて円筒の数を設定するこ
とができ、現場で簡単に目地材の高さを変更調節するこ
とができるという効果がある。Also, since this joint material is made by connecting each cylinder, the number of cylinders can be set according to the height of the mortar to be placed, and the height of the joint material can be easily changed and adjusted on site. It has the effect of being able to.
更に又円筒の素材を発泡樹脂成形品とすることによって
クッション性が大となり、モルタルの膨張収縮によく順
応するのでモルタルにクラックが生じるのを有効に防止
できるという効果がある。Furthermore, by using a foamed resin molded product as the material for the cylinder, the cushioning properties are increased and the cylinder is well adapted to the expansion and contraction of the mortar, thereby effectively preventing the formation of cracks in the mortar.
又円筒を発泡樹脂成形品とする場合は第２図に示す円筒
１ｂのように周壁の肉厚を大にすることもできる。Further, when the cylinder is made of a foamed resin molded product, the peripheral wall can be made thicker as in the cylinder 1b shown in FIG.
