Description

本発明は、ビルなどの建設現場におけるコンクリート打設時に、その外側から型枠板を補強するための桟木に係り、特に、樹脂製桟木に関するものである。   The present invention relates to a pier for reinforcing a formwork plate from the outside when placing concrete at a construction site such as a building, and more particularly to a pier made of resin.

従来の一般的なコンクリート打設工事用の桟木は、木製の角材を用い、使用後は廃材として焼却などの処理を行っていた。なお、一度の使用で廃棄せずに再利用する場合もあるが、木材であるため破損しやすく、２〜３回の再利用後は廃棄せざるをえなかった。
特開２００２−１０６１６９号公報 Conventional piers for general concrete placement work use wooden slabs, and after use, they are incinerated as waste materials. Although it may be reused without being discarded after being used once, it is easily damaged because it is made of wood, and must be discarded after being reused two or three times.
JP 2002-106169 A

上記従来の桟木は、使用後に廃棄処分をするので、木材を大量に消費することになり、木材資源の無駄遣いとなる、という問題があった。本発明は、この問題を解消することを課題とし、該課題を解決した建設工事用の樹脂製桟木を提供することを目的とする。   Since the conventional piers are disposed of after use, there is a problem that a large amount of wood is consumed, resulting in waste of wood resources. This invention makes it a subject to eliminate this problem, and it aims at providing the resin pier for construction work which solved this subject.

上記目的を達成するために、請求項１に記載した本発明は、中心板の表裏両面側に、それぞれ凹部を間においてリブ部を複数連続的に突設し、前記各リブ部と前記各凹部は、互いに嵌合しうる形状となし、かつ、一方側の各リブ部が他方側の各凹部にそれぞれ対応位置するように配置し、前記各リブ部には、前記中心板の幅方向に貫通する貫通部を形成するとともに、所定のリブ部の頂部には、貫通部の一方の開口側に向いて傾斜する固定用透孔を設けたものである。   In order to achieve the above object, according to the present invention, a plurality of rib portions are continuously provided on both the front and back sides of the center plate with a recess therebetween, and each rib portion and each recess is provided. Are arranged so that they can be fitted with each other, and each rib portion on one side is positioned so as to correspond to each concave portion on the other side, and each rib portion penetrates in the width direction of the center plate. A through-hole for fixing is formed at the top of a predetermined rib portion and is inclined toward one opening side of the through-portion.

また、請求項２に記載の本発明は、請求項１に記載の発明の構成に加えて、中心板の長手方向両端に、雄雌状に対となる前記中心板幅方向中央を境とする段部を形成し、この段部の雄部分には、前記中心板幅方向に貫通する連結用透孔を設けたことを特徴とするものである。   Moreover, in addition to the structure of the invention of Claim 1, this invention of Claim 2 makes the said center board width direction center which becomes a male-female pair in the longitudinal direction both ends of a center board as a boundary. A step portion is formed, and a male part of the step portion is provided with a connecting through hole penetrating in the center plate width direction.

以上説明したように、請求項１に記載の本発明によれば、丈夫な樹脂製なので、反復して使用することができ、木材資源のむだづかいを防止することができるうえ、複数本積み重ねるときに、下の桟木の凹部に上の桟木のリブ部を、また、下の桟木のリブ部に上の桟木１の凹部をそれぞれ嵌合するので、かさばらないだけでなく、崩れにくく、保管や運搬に便利であるという効果を奏する。   As described above, according to the present invention described in claim 1, since it is made of a strong resin, it can be used repeatedly, and it is possible to prevent waste of wood resources and to stack a plurality of them. Sometimes the upper pier rib is fitted into the lower pier recess, and the upper pier 1 recess is fitted into the lower pier rib so that they are not bulky and are not easily collapsed. There is an effect that it is convenient for transportation.

また、請求項２に記載の本発明によれば、請求項１に記載の発明の効果に加えて、複数の桟木を連結ボルトを用いて連結することが容易なので、型枠板の大きさに合わせて長い桟木を構成することができるという効果を奏する。   Further, according to the present invention described in claim 2, in addition to the effect of the invention described in claim 1, it is easy to connect a plurality of crosspieces using connecting bolts. Combined with this, it is possible to construct a long pier.

次に、本発明の好適な実施形態を添付図面の図１〜図４に基いて詳細に説明する。ここにおいて、図１は連結状態における平面図、図２は同じく連結状態における正面図、図３は使用状態を示す正面図、図４は拡大縦断側面図である。   Next, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 is a plan view in a connected state, FIG. 2 is a front view in the same connected state, FIG. 3 is a front view showing a use state, and FIG. 4 is an enlarged longitudinal side view.

図１〜図４に示すように、桟木１は、合成樹脂の一体成形によって形成するものであり、中心板２の表裏両面側に、それぞれ凹部３を間において断面がほぼ台形状のリブ部４を複数連続的に突設する。前記各リブ部４と前記各凹部３は、互いに嵌合しうる形状となし、かつ、一方側の各リブ部４が他方側の各凹部３にそれぞれ対応位置するように配置し、前記各リブ部４には、前記中心板２の幅方向に貫通する貫通部５を形成するとともに、所定のリブ部４の頂部には、貫通部５の一方の開口側に向いて傾斜する固定用透孔６を設ける。   As shown in FIGS. 1 to 4, the pier 1 is formed by integral molding of a synthetic resin, and a rib portion 4 having a substantially trapezoidal cross section on the front and back sides of the center plate 2 with a recess 3 therebetween. A plurality of continuous projections are provided. The ribs 4 and the recesses 3 are formed into shapes that can be fitted to each other, and the ribs 4 on one side are disposed so as to correspond to the recesses 3 on the other side, respectively. The part 4 is formed with a through-hole 5 that penetrates in the width direction of the center plate 2, and a fixing through-hole that is inclined toward one opening side of the through-hole 5 at the top of the predetermined rib part 4. 6 is provided.

図３及び図４に示すように、固定用透孔６には、固定用釘６ａを挿し込むと、該固定用釘６ａ先端が貫通部５の外側に突出し、型枠７に打ち込むことができるように構成してある。また、前記貫通部５は、各リブ部４の重量を軽減して桟木１全体を軽量化するはたらきもある。   As shown in FIGS. 3 and 4, when the fixing nail 6 a is inserted into the fixing through hole 6, the tip of the fixing nail 6 a protrudes outside the through portion 5 and can be driven into the mold 7. It is constituted as follows. The penetrating part 5 also serves to reduce the weight of each rib part 4 and reduce the weight of the entire pier 1.

図１〜図３に示すように、上記桟木１の長手方向両端には、幅方向中央を境とする段部８を形成し、この段部８の雄部分８ａに、幅方向に貫通する連結用透孔９を設ける。そして、二本の桟木１を連結する際には、一方の桟木１の段部８の雄部分８ａを、他方の桟木１の段部８の雄部分８ａが存在しない雌部分に嵌めて互いの連結用透孔９を連通状態となし、連結ボルト１０を挿し込んで連結するものである。なお、図３中、符号１１は型枠板の内側に打設したコンクリートである。また、図１〜図３中、符号１２は桟木１を軽量化するための透孔部である。   As shown in FIG. 1 to FIG. 3, at both ends in the longitudinal direction of the pier 1, a step portion 8 with the width direction center as a boundary is formed, and a male portion 8 a of the step portion 8 is connected through the width direction. A through hole 9 is provided. When connecting the two piers 1, the male part 8a of the step 8 of one pier 1 is fitted into the female part where the male part 8a of the step 8 of the other pier 1 is not present. The connecting through hole 9 is in a communicating state, and a connecting bolt 10 is inserted and connected. In addition, in FIG. 3, the code | symbol 11 is the concrete cast | injected inside the formwork board. 1 to 3, reference numeral 12 denotes a through hole portion for reducing the weight of the pier 1.

以上のように構成した桟木１は、図３に示すように、コンクリートの打設に際し、型枠板７の大きさに合わせた長さとなるように、単数本あるいは複数本連結し、型枠板７の外側に縦に固定する。前記連結にあたっては、一方の桟木１の段部８の突出部８ａを、他方の桟木１の段部８の突出部８ａが存在しない雌部分に嵌めて互いの連結用透孔９を連通させ、連結ボルト１０を挿し込む。また、型枠板７に固定するには、各固定用透孔５に固定釘６を挿し込み、先端を斜めに型枠板７に打ち込む。   As shown in FIG. 3, the pier 1 configured as described above is connected to a single or a plurality of frames so as to have a length corresponding to the size of the mold plate 7 when placing concrete. 7 is fixed vertically outside. In the connection, the protruding portion 8a of the step portion 8 of one pier 1 is fitted into a female portion where the protruding portion 8a of the step portion 8 of the other pier 1 is not present, and the connecting through holes 9 are communicated with each other. Insert the connecting bolt 10. Further, in order to fix to the mold plate 7, the fixing nails 6 are inserted into the fixing through holes 5, and the tips are driven into the mold plate 7 obliquely.

また、図２に示すように、桟木１は、複数本積み重ねるときに、下の桟木１の凹部３に上の桟木１のリブ部４を、さらに、下の桟木１のリブ部４に上の桟木１の凹部３をそれぞれ嵌合するので、かさばらないだけでなく、崩れにくく、保管や運搬に便利であるという利点がある。   Further, as shown in FIG. 2, when a plurality of piers 1 are stacked, the rib portion 4 of the upper pier 1 is placed in the recess 3 of the lower pier 1, and the rib portion 4 of the lower pier 1 is further raised. Since the concave portions 3 of the pier 1 are respectively fitted, there is an advantage that not only it is not bulky but also difficult to collapse and convenient for storage and transportation.

なお、本発明は、上記実施形態になんら限定されるものではなく、例えば、リブ部４の形状は、上記実施形態のような台形ではなく、四角形あるいは円形であってもよい。   In addition, this invention is not limited to the said embodiment at all, For example, the shape of the rib part 4 may not be a trapezoid like the said embodiment but square or circular.
