Description

本発明は、鉄筋コンクリート構造物における非構造壁の内部またはそれと柱との接合部近傍に埋設される垂直スリット材をコンクリート打設前に設置する作業において、その垂直スリット材を所定位置に支持するための固定具を用いた支持構造に関するものである。 The present invention is to support the vertical slit material in a predetermined position in the operation of installing the vertical slit material embedded in the inside of the non-structural wall in the reinforced concrete structure or in the vicinity of the joint between the column and the pillar before placing the concrete. It is related with the support structure using the fixing tool of .

近年、マンションや共同住宅等の鉄筋コンクリート造の建物では、柱と壁などの境界部分に層間変位に対する力学的な不連続部となる構造スリットを形成する目的で、スリット材と称される緩衝材を使用する工法が普及している。このスリット材は、壁を貫通もしくは所定の壁厚を残すように埋設され、当該スリット材を介して建造物が分割されていることから、地震による外力を受けたときには、柱などに生じる剪断応力をスリット材で吸収緩和してその伝達を遮断することにより、柱などの剪断破壊や脆性破壊を回避するようになっている。そして、この種の耐震用スリット材には、建造物の上層階の壁（非構造壁）と下層階の梁との間に設ける水平スリット材の他に、腰壁あるいは垂れ壁や、これに連設される柱との接合部の近傍などに埋設される垂直スリット材がある。   In recent years, in reinforced concrete buildings such as condominiums and apartment buildings, a buffer material called a slit material has been used to form a structural slit that becomes a mechanical discontinuity against inter-layer displacement at the boundary between columns and walls. The construction method used is widespread. This slit material is embedded so as to penetrate the wall or leave a predetermined wall thickness, and since the building is divided through the slit material, shear stress generated on the pillars etc. when subjected to an external force due to an earthquake By absorbing and relaxing with a slit material and blocking its transmission, shear fracture and brittle fracture of pillars and the like are avoided. This type of earthquake-resistant slit material includes a horizontal slit material provided between the upper floor wall (non-structural wall) of the building and the lower floor beam, as well as a waist wall or a hanging wall, There is a vertical slit material embedded in the vicinity of a joint with a column that is continuously provided.

ところで、上記垂直スリット材を壁部に埋設する場合、コンクリートを打設する前に、その垂直スリット材を壁型枠間に設置しておく必要がある。一般に、この施工方法としては、予め、垂直スリット材が設けられる位置に目地材を釘等によって固定させた壁型枠の一方側の型枠（先行型枠）を建て込んだ後、スリット材本体の両側面部にそれぞれ嵌着した保持部材のうち、一方の保持部材を先行型枠に固定した目地材に嵌合させる。そして、他方側の型枠（返し型枠）を建て込むのと同時にその型枠に固定されている目地材を、スリット材本体の他方の保持部材に嵌合させることで、壁型枠間に垂直スリット材が設置されることになる。しかし、この施工方法において、保持部材はスリット材本体と嵌合した状態で一体化され、また、壁型枠に固定した目地材とは嵌合した状態で接続されているだけであるため、返し型枠に固定した目地材を保持部材に嵌合させる際に、先行型枠側の目地材から保持部材やスリット材本体がずれたり、外れてしまったりする問題があった。しかも、保持部材と係合する目地材は、それぞれ壁型枠を建て込む前に固定されることから取付位置の精度が悪く、垂直スリット材を設置する位置からずれて取り付けられると、返し型枠側の目地材を保持部材に嵌合させる際に垂直スリット材が型枠に対して傾いてしまうことになる。このことは、先行型枠側の保持部材における接続部分にモーメントを生じさせることになり、目地材から保持部材やスリット材本体などが外れてしまう一因にもなっていた。これらのことから、壁型枠間に垂直スリット材を設置する作業において、返し型枠を建て込むことは非常に手間がかかるものであった。   By the way, when the vertical slit material is embedded in the wall, it is necessary to install the vertical slit material between the wall molds before placing the concrete. In general, the construction method is as follows. After installing a formwork on one side of a wall formwork (predecessor formwork) with a joint material fixed with a nail or the like at a position where a vertical slit material is provided in advance, the slit material body Of the holding members fitted to the both side surfaces, one holding member is fitted to the joint material fixed to the preceding mold. The joint material fixed to the mold at the same time that the other mold (return mold) is built is fitted into the other holding member of the slit material main body, so that the wall mold A vertical slit material will be installed. However, in this construction method, the holding member is integrated in a state of being fitted to the slit material body, and is only connected in a state of being fitted to the joint material fixed to the wall formwork. When fitting the joint material fixed to the mold into the holding member, there has been a problem that the holding member and the slit material main body are displaced or detached from the joint material on the preceding mold side. Moreover, the joint material that engages with the holding member is fixed before the wall mold is built, so the accuracy of the mounting position is poor. When the side joint material is fitted to the holding member, the vertical slit material is inclined with respect to the mold. This causes a moment in the connecting portion of the holding member on the preceding mold side, which is one cause of the holding member, the slit material main body, and the like being detached from the joint material. For these reasons, it has been very troublesome to install the return mold in the operation of installing the vertical slit material between the wall molds.

これらの問題点を解消するために、支持片に形成した脚片または鍔部と係合する挟持部が設けられるとともに、その他側面の少なくとも一箇所に釘止部を設けた垂直スリット材用の取付具が開示されている（特許文献１参照）。この特許文献１に記載されている取付具は、支持片の脚片等を挟持した状態で釘止部を介して壁型枠に固定することから、型枠と支持片とが強固に接続することができるものであった。
実開昭５９−９２１４６号公報 In order to solve these problems, a mounting portion for a vertical slit material in which a nipping portion that engages with a leg piece or a collar portion formed on a support piece is provided and a nail stop portion is provided on at least one other side surface is provided. A tool is disclosed (see Patent Document 1). Since the fixture described in Patent Document 1 is fixed to the wall formwork through the nail stoppers with the leg pieces of the support piece being sandwiched, the formwork and the support piece are firmly connected. It was something that could be done.
Japanese Utility Model Publication No.59-92146

しかしながら、上記取付具は垂直スリット材を設置する際に型枠の内側から釘を打ち込むことから、保持部材をスリット材本体から予め外しておき、建て込む前の返し型枠に複数の取付具を所定間隔に打ち込んで、その保持部材を固定する必要があった。この固定作業は、取付具の個数を多くするばかりでなく、その都度、型枠に釘止めする作業が増えてしまうことから、垂直スリット材の施工性を悪くするものであった。さらに、返し型枠を建て込む時に、型枠に固定した保持部材を直接スリット材本体に嵌合しなければならないため、型枠同士の位置合わせが面倒になるばかりか、スリット材本体が容易に変形する材質である場合には、保持部材を嵌合させることが非常に困難となってしまい、返し型枠を建て込むことはかえって手間がかかる作業になっていた。   However, since the above-mentioned fixture drives a nail from the inside of the mold when installing the vertical slit material, the holding member is removed from the slit material body in advance, and a plurality of fixtures are attached to the return mold before being built. It is necessary to fix the holding member by driving it at a predetermined interval. This fixing work not only increases the number of fixtures, but also increases the work of nailing to the formwork each time, thus deteriorating the workability of the vertical slit material. In addition, when installing the return formwork, the holding member fixed to the formwork must be fitted directly into the slit material body, which not only makes the alignment of the formwork troublesome, but also makes the slit material body easier. In the case of a deformable material, it is very difficult to fit the holding member, and it has been a troublesome work to install the return form.

本発明は、これらの問題点に鑑みなされたもので、少ない部品点数により返し型枠を建て込む際の作業性が向上するとともに、壁型枠間に垂直スリット材を精度良く設置することができる垂直スリット材用固定具を用いた垂直スリット材の支持構造を提供することを目的とするものである。 The present invention has been made in view of these problems, and improves workability when building a return formwork with a small number of parts, and allows a vertical slit material to be accurately placed between wall formwork. An object of the present invention is to provide a support structure for a vertical slit material using a fixture for the vertical slit material .

前記課題を解決するため、本発明は、コンクリート構造物の壁部またはその柱際の接合部分の壁型枠間に設けられ、それら壁型枠にそれぞれ固定される目地材と、前記目地材に対して係合可能な保持部材と、それら保持部材に嵌合されるスリット材本体からなる垂直スリット材とを、コンクリート打設時に所定位置で、前記垂直スリット材の下端側を垂直スリット材用固定具により支持する垂直スリット材の支持構造であって、前記垂直スリット材用固定具が、コンクリート等の壁型枠設置面上に固定される底板部と、この底板部から立ち上がり、前記垂直スリット材の保持部材に挿着可能な立ち上がり部を備えているという技術手段を採用した。 In order to solve the above-described problems, the present invention provides a joint material provided between wall molds of a wall portion of a concrete structure or a joint portion thereof and fixed to the wall molds, and the joint material . a holding member engageable against, and a vertical slit material made of slit material body to be fitted to them holding member, at a predetermined position in the concrete after casting, fixing the lower side vertical slit material of the vertical slit member A vertical slit material supporting structure supported by a tool , wherein the vertical slit material fixture is fixed on a wall formwork installation surface such as concrete, and rises from the bottom plate portion, and the vertical slit material The technical means of having a rising portion that can be inserted into the holding member is employed.

垂直スリット材の支持構造に用いる上記構成の垂直スリット材用固定具は、底板部がコンクリート等の壁型枠設置面に固定されることから、壁型枠に固定された目地材と保持部材とを容易に係合させることが可能になり、返し型枠を建て込む際の作業性が向上する。さらに、立ち上がり部は垂直スリット材の保持部材に挿入されて支持するため、垂直スリット材と固定具との接続を強固にすることができ、保持部材をスリット材本体から外すことなく壁型枠間に垂直スリット材を設置することができる。 Since the bottom plate portion is fixed to a wall formwork installation surface such as concrete, the fixture for the vertical slit material having the above configuration used for the support structure of the vertical slit material includes a joint material and a holding member fixed to the wall formwork. Can be easily engaged, and workability at the time of installing the return formwork is improved. Furthermore, since the rising portion is inserted into and supported by the holding member of the vertical slit material, the connection between the vertical slit material and the fixture can be strengthened, and the wall member can be secured without removing the holding member from the slit material body. Vertical slit material can be installed in

本発明の垂直スリット材の支持構造によれば、それに用いる垂直スリット材用固定具を、壁型枠を建て込む前にコンクリートなどの壁型枠設置面上に底板部を固定することから、壁型枠間の所定位置に垂直スリット材を精度良く設置することができる。さらに、垂直スリット材と水平スリット材が併用される場合であっても、立ち上がり部が垂直スリット材を支持するとともに、水平スリット材の位置決めも兼ねるので、耐震スリット材の施工精度を大幅に改善することが可能になる。また、立ち上がり部が垂直スリット材の保持部材に挿入されて支持することにより、保持部材やスリット材本体が先行型枠の目地材と強固に接続されるため、返し型枠に固定した目地材はスリット材本体に嵌合している保持部材に係合し易くなり、垂直スリット材を壁型枠間に設置する作業性が向上する。 According to the vertical slit material supporting structure of the present invention, the vertical slit material fixing tool used for the vertical slit material fixing member is fixed to the bottom plate portion on the wall formwork installation surface such as concrete before the wall formwork is built. The vertical slit material can be accurately installed at a predetermined position between the molds. Furthermore, even when a vertical slit material and a horizontal slit material are used in combination, the rising portion supports the vertical slit material and also serves as a positioning for the horizontal slit material, greatly improving the construction accuracy of the earthquake-resistant slit material. It becomes possible. In addition, since the rising part is inserted into and supported by the holding member of the vertical slit material, the holding member and the slit material main body are firmly connected to the joint material of the preceding mold, so the joint material fixed to the return mold is It becomes easy to engage with the holding member fitted to the slit material body, and the workability of installing the vertical slit material between the wall molds is improved.

本発明の垂直スリット材の支持構造に係る垂直スリット材用固定具は、鋼製や合成樹脂製のものなどその材質について特に問うものではなく、その製造方法についても、底板部と立ち上がり部とをプレス加工などにより一体成形したものや、溶接により別体の立ち上がり部を底板部に固着したものなど特に限定されない。また、固定具を構成する底板部や立ち上がり部の形状は、後述する実施例に限定されるものではなく、底板部については、例えば、平板状以外にも下面が曲面に形成されたものなどでも良く、立ち上がり部についても、垂直スリット材の保持部材に挿入し易くするため、先端を尖らせた形態にするなど、種々の形状等が実施可能である。また、固定具の底板部をコンクリート等の壁型枠設置面上に固定する手段としては、コンクリート釘等を用いて固定するだけでなく、接着剤などにより底板部下面と壁型枠設置面とを固定することも可能である。以下、図面に基づき、本発明の実施例について説明する。 The vertical slit material fixture according to the support structure of the vertical slit material of the present invention does not particularly ask about its material such as steel or synthetic resin, and the manufacturing method includes a bottom plate portion and a rising portion. There is no particular limitation such as one integrally formed by press working or the like, and another rising portion fixed to the bottom plate portion by welding. In addition, the shape of the bottom plate portion and the rising portion constituting the fixture is not limited to the embodiments described later. For the bottom plate portion, for example, a plate whose bottom surface is formed in a curved surface other than a flat plate shape, etc. For the rising part, various shapes such as a sharpened tip can be implemented to facilitate insertion into the holding member of the vertical slit material. In addition, as a means for fixing the bottom plate part of the fixture on the wall formwork installation surface such as concrete, not only using a concrete nail, etc., but also using an adhesive or the like, the bottom plate part lower surface and the wall formwork installation surface Can also be fixed. Embodiments of the present invention will be described below with reference to the drawings.

図１ないし図３は、それぞれ本発明の垂直スリット材の支持構造に係る垂直スリット材用固定具のそれぞれ平面図、正面図及び右側面図である。図示のように、垂直スリット材用固定具１は、平板状の鋼材の一方側を上方に折り曲げて正面視略Ｌ字状の形態を成したものであり、底板部２と立ち上がり部３によって構成されている。そして、その底板部２には、釘等によりコンクリート等の壁型枠設置面上に固定するための貫通孔４が設けられている。なお、本実施例のように、固定具自体の回転を防ぐことから貫通孔の数は２個以上設けることが望ましいが、特に１個でも設置面に固定することは可能であり、その位置についても任意に設定することができる。さらに、本実施例では、立ち上がり部の幅を底板部の幅より小さく形成したものを例示したが、それぞれの幅を同一にしたものや、立ち上がり部の幅が底板部より大きく形成したものであっても良く、特段、垂直スリット材の保持部材に挿入可能な幅であれば問題はない。 1 to 3 are a plan view, a front view, and a right side view, respectively, of a fixture for a vertical slit material according to the support structure for a vertical slit material of the present invention. As shown, the fixture 1 for vertical slit material, which made a front generally L-shaped configuration by bending one side of a flat steel upward, the bottom plate portion 2 and the rising portions 3 It is configured. The bottom plate portion 2 is provided with a through hole 4 for fixing on a wall formwork installation surface such as concrete with a nail or the like. In addition, as in this embodiment, it is desirable to provide two or more through holes in order to prevent rotation of the fixture itself, but even one can be fixed to the installation surface, and its position Can also be set arbitrarily. Furthermore, in the present embodiment, an example in which the width of the rising portion is formed smaller than the width of the bottom plate portion is exemplified, but the width of each rising portion is made larger than that of the bottom plate portion. There is no particular problem as long as the width can be inserted into the holding member of the vertical slit member.

次に、本発明に係る垂直スリット材の支持構造において、垂直スリット材用固定具により支持される垂直スリット材について説明する。図４に示すように、垂直スリット材Ｖは、一対の壁型枠Ｗに固定された目地材５，６に対して係合可能な保持部材７，８と、その保持部材７，８と嵌合する発泡プラスチック等からなるスリット材本体９により構成されている。そして、その保持部材７，８には、目地材５，６と係合する係合片７ａ，８ａが設けられるとともに、型枠脱型後にコンクリート躯体表面から浸入する水を止める水返し片７ｂ，８ｂが設けられている。また、係合片７ａ，８ａと水返し片７ｂ，８ｂの中間部には支持片７ｃ，８ｃが形成され、その支持片７ｃ，８ｃと水返し片７ｂ，８ｂによって、固定具の立ち上がり部が挿着可能になっている。このように、保持部材７，８が立ち上がり部に直接支持される構成にすれば、保持部材７，８の固定度が増すことから目地材５，６やスリット材本体９との接続が強固なものになり、スリット材本体９などが保持部材７，８から外れるといった従来の問題は解消される。なお、保持部材７，８に支持片７ｃ，８ｃが形成されていない場合であっても、固定具の立ち上がり部を保持部材７，８とスリット材本体９との間に挿入させることによって垂直スリット材Ｖを支持することが可能であり、本発明と同じ効果を得ることができる。 Next, the vertical slit material supported by the vertical slit material fixture in the vertical slit material support structure according to the present invention will be described. As shown in FIG. 4, vertical slit material V includes a engageable with the holding members 7 and 8 against the joint member 5, 6 which is fixed to a pair of wall formwork W, and its holding members 7 and 8 It is comprised by the slit material main body 9 which consists of a foaming plastic etc. to fit. The holding members 7 and 8 are provided with engagement pieces 7a and 8a that engage with the joint materials 5 and 6, and a water return piece 7b that stops water entering from the surface of the concrete frame after demolding. 8b is provided. Further, the engaging piece 7a, 8a and water flashing piece 7b, the support piece 7c an intermediate portion of 8b, 8c are formed, the support piece 7c, 8c and water flashing piece 7b, the 8b, the rising portion of the solid Teigu Can be inserted. As described above, if the holding members 7 and 8 are directly supported by the rising portion, the fixing degree of the holding members 7 and 8 is increased, so that the connection with the joint materials 5 and 6 and the slit material body 9 is strong. Thus, the conventional problem that the slit body 9 and the like are detached from the holding members 7 and 8 is solved. Even when the supporting members 7c and 8c are not formed on the holding members 7 and 8, the vertical slits can be obtained by inserting the rising portion of the fixture between the holding members 7 and 8 and the slit material body 9. The material V can be supported, and the same effect as the present invention can be obtained.

次に、上記垂直スリット材用固定具を用いて、壁部に形成する開口部分とスラブとの間、すなわち腰壁に垂直スリット材を設置する場合の施工方法について説明する。図５は、壁型枠間に垂直スリット材が設置された状況を示す概要図である。先ず、釘等（図示せず）を用いて所定位置に目地材５を取り付けた先行型枠Ｗ１をスラブＳ上に建て込んだ後、そのスラブ面における垂直スリット材Ｖが設置される位置に、固定具１の底板部２をコンクリート釘（図示せず）などにより固定させる。そして、スリット材本体９の両側面部にそれぞれ嵌合した保持部材７，８のうち、一方の保持部材７の係合片７ａを前記先行型枠Ｗ１の目地材５に係合させながら、スラブＳ面上に固定した固定具１の立ち上がり部３を保持部材７の水返し片７ｂと支持片７ｃの間に挿入させて落し込むことにより、垂直スリット材Ｖが固定具１によって支持される。さらに、開口部を形成するための開口枠Ｐにおいて、スラブＳ面上に固定した固定具の鉛直線上の位置に、同固定具１を釘等（図示せず）により取り付け、その固定具１の立ち上がり部３を先行型枠Ｗ１に接続された垂直スリット材Ｖの保持部材７の一部に挿入することで、開口枠Ｐと垂直スリット材Ｖが固定する。最後に、目地材６が所定位置に取り付く返し型枠Ｗ２をスラブＳ上に建て込みながら、その目地材６をスリット材本体９の他方の保持部材８の係合片８ａに係合させることによって、壁型枠Ｗ１，Ｗ２間の所定位置に垂直スリット材Ｖが設置されることになる。このように、本発明の垂直スリット材の支持構造による施工方法において、先行型枠Ｗ１側の保持部材７が固定具１によって強固に接続されるため、返し型枠Ｗ２側の目地材６を保持部材８の係合片８ａに係合させても先行型枠Ｗ１側の目地材５から保持部材６やスリット材本体９が外れることはない。なお、本実施例では先行型枠側の保持部材にのみ固定具を使用したが、返し型枠側の保持部材を固定具によって支持したり、両方の保持部材を支持するようにしても良く、その設置数や支持する位置などは適宜に設定することができる。ちなみに、返し型枠側の保持部材に固定具を支持させるようにすれば、返し型枠を建て込む際に目地材と保持部材とが、より係合し易くなる。また、コンクリート等の壁型枠設置面上に固定する際の固定具の向きは、特に問うものではなく、施工状況に応じて固定できることは言うまでもない。 Next, the construction method in the case of installing a vertical slit material between the opening part formed in a wall part and a slab, ie, a waist wall, using the said fixing tool for vertical slit materials is demonstrated. FIG. 5 is a schematic diagram showing a situation in which a vertical slit member is installed between wall molds. First, nails prior formwork W 1 fitted with a joint compound 5 in place using a (not shown) After built up on the slab S, the position where the vertical slit material V at the slab surface is placed The bottom plate portion 2 of the fixture 1 is fixed with a concrete nail (not shown) or the like. Of the holding members 7 and 8 fitted respectively to the both side surfaces of the slit material body 9, while the engaging piece 7a of one of the holding member 7 is engaged with the joint member 5 of the preceding mold W 1, slab The vertical slit member V is supported by the fixture 1 by inserting and dropping the rising portion 3 of the fixture 1 fixed on the S surface between the water return piece 7 b and the support piece 7 c of the holding member 7. Further, in the opening frame P for forming the opening, the fixing device 1 is attached to a position on the vertical line of the fixing device fixed on the slab S surface by a nail or the like (not shown). by inserting a portion of the holding member 7 of the prior formwork W 1 connected to a vertical slit material V rising portion 3, opening frame P and a vertical slit material V is fixed. Finally, the joint member 6 while like an anchor barbs formwork W 2 that attaches to a predetermined position on the slab S, to engage the joint member 6 in the engaging piece 8a of the other holding member 8 of the slit material body 9 Thus, the vertical slit material V is installed at a predetermined position between the wall molds W 1 and W 2 . Thus, in the construction process by the support structure of the vertical slit material of the present invention, since the preceding formwork W 1 of the holding member 7 is firmly connected by fasteners 1, the return-type frame W 2 side joint member 6 It is engaged in the engaging piece 8a holding a joint material 5 prior formwork W 1 side member 6 and the slit material body 9 of the holding member 8 will not come off. In this embodiment, the fixing tool is used only for the holding member on the preceding mold side, but the holding member on the return mold side may be supported by the fixing tool, or both holding members may be supported. The number of installation, the position to support, etc. can be set suitably. By the way, if the fixing member is supported by the holding member on the return mold frame side, the joint material and the holding member are more easily engaged when the return mold is built. Moreover, it is needless to say that the direction of the fixing tool when it is fixed on the wall formwork installation surface such as concrete can be fixed according to the construction situation.

図６及び図７は、本発明の垂直スリット材の支持構造に係る他の実施例を示した垂直スリット材用固定具のそれぞれ平面図及び正面図である。なお、固定具の構成において、前記第１実施例と重複する部分については詳細な説明を省略する。図示の固定具１０は、底板部１１の形状が異なる以外は同様の構成になっている。そして、その底板部１１は、平板状の鋼材の一端から中央にかけて切り込みを２箇所設け、その切り込まれた間の部分のみを上方に折り曲げて、立ち上がり部１２を形成することによって正面視逆Ｔ字状の形態を成している。このように、立ち上がり部１２を底板部１１の中間部に設けることで、垂直スリット材を支持する際に固定具１０の安定度が向上する。また、水平スリット材が併用される場合にこの固定具１０を適用すれば、水平スリット材が底板部１１の上面に載置されることにより、固定具１０自体の固定度が増す効果が得られるとともに、水平スリット材の本体の端面が立ち上がり部１２の側面に当接することで、水平スリット材の位置決め機能を奏することになる。 6 and 7 are a plan view and a front view, respectively, of a fixture for a vertical slit material showing another embodiment according to the support structure for the vertical slit material of the present invention. Incidentally, omitted in the configuration of the solid Teigu, a detailed description of parts common to those in the first embodiment. The illustrated fixture 10 has the same configuration except that the shape of the bottom plate portion 11 is different. The bottom plate portion 11 is provided with two cuts from one end to the center of the flat steel material, and only the portion between the cuts is bent upward to form the rising portion 12 so that the front view is reversed T It is shaped like a letter. Thus, by providing the rising portion 12 at the intermediate portion of the bottom plate portion 11, the stability of the fixture 10 is improved when the vertical slit material is supported. Further, by applying the fastener 10 of this when the horizontal slit material in combination, by the horizontal slits material is placed on the upper surface of the bottom plate portion 11, the effect of fixing of the fixture 10 itself increases yield At the same time, the end face of the main body of the horizontal slit material comes into contact with the side surface of the rising portion 12 to perform the function of positioning the horizontal slit material.

次に、上記垂直スリット材用固定具により、垂直スリット材Ｖと水平スリット材Ｈが併用して設置される場合の施工方法について説明する。なお、上記と同様に、前記第一実施例と重複する部分については詳細な説明を省略する。図８に示すように、先行型枠の建て込みが行われた後、スラブＳ等のコンクリート面上に水平スリット材Ｈ及び垂直スリット材Ｖが設置される位置に、固定具１０をコンクリート釘（図示せず）などで固定する。そして、水平スリット材Ｈを、その端面部が立ち上がり部１２の側面に当接するように底板部１１上に設置する。しかる後、垂直スリット材Ｖのスリット材本体の両側面部にそれぞれ嵌合した保持部材１４の一端側の係合片１４ａを、前記先行型枠の目地材１３に係合させながら、保持部材１４の一部を固定具１０の立ち上がり部１２に挿入して、水平スリット材Ｈ上に落とし込むことにより、垂直スリット材Ｖが固定具１０に支持される。なお、前記のような水平スリット材Ｈが併用される場合、固定具１０は、水平スリット材Ｈを設置した後でも垂直スリット材Ｖの保持部材を立ち上がり部１２に挿入できるように、その高さを水平スリット材Ｈの厚みより大きくする必要がある。また、本実施例は前記第一実施例と異なり、開口部が形成されない壁部に垂直スリット材等が設置される場合について説明したものであるため、壁型枠の上端側には開口枠のような型枠が取り付くことがない。よって、保持部材の上方側では固定具を用いることはできないが、本発明において、固定具は少なくともスラブ等のコンクリート面上に固定していれば、即ち、垂直スリット材の下端側のみを固定するだけでも十分に垂直スリット材を支持することが可能である。 Next, the vertical slit material fixture for installation method will be described in the case of the vertical slit member V and the horizontal slit member H is placed in combination. In the same manner as described above, detailed description of the same parts as those in the first embodiment will be omitted. As shown in FIG. 8, after the preceding form is installed, the fixture 10 is placed on the concrete nail (at the position where the horizontal slit material H and the vertical slit material V are installed on the concrete surface such as the slab S. Fix with a not shown). Then, the horizontal slit material H is installed on the bottom plate portion 11 so that the end surface portion thereof is in contact with the side surface of the rising portion 12. Thereafter, the engaging pieces 14a on one end side of the holding member 14 fitted to both side portions of the slit material main body of the vertical slit material V are engaged with the joint material 13 of the preceding form frame while the holding member 14 is engaged. The vertical slit material V is supported by the fixture 10 by inserting a part thereof into the rising portion 12 of the fixture 10 and dropping it onto the horizontal slit material H. In the case where the horizontal slit material H such as the are used together, the solid Teigu 10, as the retaining member of the vertical slit material V even after installing the horizontal slit material H can be inserted into the rising portion 12, the height It is necessary to make the thickness larger than the thickness of the horizontal slit material H. In addition, unlike the first embodiment, this embodiment has been described for the case where a vertical slit material or the like is installed in a wall portion where no opening portion is formed. Such a formwork is not attached. Therefore, a fixing tool cannot be used on the upper side of the holding member, but in the present invention, the fixing tool is fixed at least on the concrete surface such as a slab, that is, only the lower end side of the vertical slit material is fixed. It is possible to support the vertical slit material sufficiently.

なお、上記実施例では、底板部に１つの立ち上がり部を備えた固定具によりスリット材本体の両側面部にそれぞれ嵌合した保持部材の一方を支持する事例について説明したが、これに限定されるわけではなく、例えば、２つの立ち上がり部を底板部に設けた固定具によって両方の保持部材に挿入できるような形態であっても良い。さらに、垂直スリット材の保持部材を立ち上がり部に挿入させた際に容易に抜け出すことがないようにするため、立ち上がり部に凸部などの抜止手段を設けたりするなど、適宜、本発明の技術思想内での種々の設計変更はもちろん可能である。   In the above-described embodiment, the example in which one of the holding members respectively fitted to the both side surface portions of the slit material body is supported by the fixture having one rising portion on the bottom plate portion, is not limited to this. Instead, for example, a configuration in which the two rising portions can be inserted into both holding members by a fixture provided on the bottom plate portion may be employed. Further, in order to prevent the vertical slit member from being easily pulled out when the holding member is inserted into the rising portion, a technical means of the present invention is appropriately provided, such as providing a retaining means such as a convex portion at the rising portion. Of course, various design changes are possible.
