Abstract
Description
本発明は、基礎用型枠パネル構造体に関し、特に連通孔と型枠とが一体化される基礎用型枠パネル構造体に関する。 The present invention relates to a base formwork panel structure, and more particularly to a base formwork panel structure in which a communication hole and a formwork are integrated.
基礎工事や壁体工事等において、躯体コンクリートの立面を構成する型枠の堰板として、従来は木枠パネルが用いられていたが、近年では、作業性を高めるために金属製の型枠パネルが採用されるようになっている。金属製型枠パネルには、金属薄板を角波形に屈曲成形したキーストンプレートやリブラスなどがあり、これらは躯体コンクリートの硬化後に解体・除去することなく埋め殺し状態に放置する(いわゆる捨てパネルとする)ようにして用いられる(例えば、特許文献1参照)。 In foundation work and wall construction, wooden frame panels have been used as the dam plate of the frame that forms the vertical surface of the frame concrete. However, in recent years, metal molds have been used to improve workability. Panels are being adopted. Metal formwork panels include keystone plates and rib laths that are formed by bending a thin metal plate into a square waveform, and these are left in a buried state without being dismantled and removed after the concrete is hardened (so-called discarded panels) (See, for example, Patent Document 1).
一方、このような基礎や壁面にパイプ工事、配線工事、工事後の部材の運び出しあるいは将来のメンテナンスに備えて、連通孔を設けることが行なわれている。このような連通孔は、例えば、配管、配線、排水用の比較的径の小さいものから、いわゆる人通孔と呼ばれる作業員が通過できるようなものまで種々のものがある。しかし、このような連通孔を作業現場で基礎や壁面に作成するのは手数がかかる。特に人通孔の場合、コンクリート打設中または打設後すぐに作業員が通過できるように予め開口が必要であり、開口がない場合常に各ピットの床に開口が必要になる。この床の開口は後々塞がなければならないので非常に手間が掛かるため人通孔プレートには床の開口を少なくする効果がある。
ところで、このような連通孔を現場で作成して木枠パネルや金属製の型枠パネルに取り付けたり、コンクリート打設後に穴を開けたりするにはそれなりの手間が必要であり、作業に時間がかかり結果的に高価なものになることが多い。
本発明はこの点を改良して、連通孔用のパイプを予め作りつけておいて、型枠パネルとともに作業時に埋め込んで埋め殺し状態で用いることで、現場での作業が容易な連通孔と型枠とが一体化された基礎用型枠パネル構造体の実現を課題とする。
By the way, creating such a communication hole on site and attaching it to a wooden frame panel or a metal formwork panel, or making a hole after placing concrete, requires a certain amount of work, and the work takes time. This often results in expensive products.
The present invention improves on this point, and a communication hole and a mold that are easy to work in the field are prepared by pre-fabricating a pipe for a communication hole and using it in a buried state together with a formwork panel. An object is to realize a foundation formwork panel structure integrated with a frame.
上記課題を解決するため、本発明の請求項1に記載の発明は、躯体コンクリートの両立面を構成する2組の型枠の堰板として用いる金属製の型枠パネルとこの型枠パネルに取り付けられ前記躯体コンクリートを貫通する連通管とを有する基礎用型枠パネル構造体であって、前記連通管の管径よりも大き目の穴径の開口を有し、この開口に前記連通管を通して前記連通管を支持するカバープレートと、このカバープレートを前記型枠パネルに取り付ける締結手段とを有し、前記型枠パネルにはその裏面又は表面側に長手方向に延びるリブ部が幅方向に所定の間隔で平行に設けられており、前記連通管は両面の前記型枠パネルのリブ部間の長さよりも所定長さ以上長い管長を有することを特徴とする。
In order to solve the above-mentioned problems, the invention according to
上記課題を解決するため、本発明の請求項2に記載の発明は、請求項1に記載の基礎用型枠パネル構造体において、前記連通管の切断端面を覆う保護キャップ手段を有することを特徴とする。
In order to solve the above-mentioned problems, the invention described in
本発明の基礎用型枠パネル構造体は以上のようになっているので、型枠パネルと連通管とからなる構造体を現場で容易に構成することができると共に、躯体コンクリートの硬化後に解体・除去する必要がないので、作業全体を廉価に達成することができる。
また、連通管の切断端面を保護キャップで覆うために、建設後も切口は安全である。
Since the formwork panel structure for a foundation of the present invention is as described above, a structure composed of a formwork panel and a communication pipe can be easily configured on the site, and dismantling / Since it does not need to be removed, the entire operation can be accomplished inexpensively.
In addition, since the cut end face of the communication pipe is covered with a protective cap, the cut end is safe even after construction.
以下本発明を図を参照に詳細に説明する。
図1は本発明の基礎用型枠パネル構造体の一実施の形態の外観斜視図である。また、図2、図3および図4はこの実施の形態の型枠パネル構造体の施工手順を示す正面図、図5はこの基礎用型枠パネル構造体の平面図、図6はこの基礎用型枠パネル構造体の縦断面図である。また、図7はカバープレートの寸法を示す図表である。図1ないし図6において、符号1は型枠パネル、符号2はカバープレート、符号3は鞘管、符号4は半裁管、符号5は保護キャップ、符号6は取り付け穴である。連通管には、配線、パイプ配置用および人通管として筒状の鞘管3が、排水用には半裁管4が用いられる。鞘管3は金属管、ゴム管または塩化ビニール管が用いられる。保護キャップ5にはゴムまたは塩化ビニールを用いて、作業時、通過時の安全を図るようにしても良い。
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is an external perspective view of an embodiment of a basic form panel structure of the present invention. 2, 3 and 4 are front views showing the construction procedure of the formwork panel structure of this embodiment, FIG. 5 is a plan view of this formwork panel structure for foundation, and FIG. 6 is for this foundation. It is a longitudinal cross-sectional view of a formwork panel structure. FIG. 7 is a chart showing the dimensions of the cover plate. 1 to 6,
型枠パネルには、裏面又は表面側に長手方向に延びるリブ部が幅方向に所定の間隔で平行に設けられおり、また、各リブ部間の略中央に位置して、リブ部と平行でかつ長手方向に延びる多数のスリットが、所定の間隔で一直線上に設けられている。リブ部はパネル強度を増大することができると共に、リブ部を相互に重ねることで型枠パネルの連結が容易になる。
また、作業現場において、型枠のコーナー部を形成する場合、工事現場の状況に応じて、型枠パネルを、その幅方向中央部に位置するスリット列の部分を所要の任意角度に折り曲げて、型枠コーナー部パネルとすることができる。
In the formwork panel, rib portions extending in the longitudinal direction on the back surface or the front surface side are provided in parallel in the width direction at predetermined intervals, and are located at substantially the center between the rib portions and in parallel with the rib portions. A large number of slits extending in the longitudinal direction are provided in a straight line at a predetermined interval. The rib portion can increase the panel strength, and it is easy to connect the formwork panels by overlapping the rib portions.
Also, when forming the corner of the formwork at the work site, depending on the situation at the construction site, bend the part of the formwork panel at the slit row located at the center in the width direction to the required arbitrary angle, It can be a formwork corner panel.
基礎用型枠パネル構造体を施工する場合には、まず、図2に示すように、型枠パネル1上の連通管としての鞘管3や半裁管4の取り付け位置に切断機を用いて取り付け穴6をあける。取り付け穴6は鞘管3および半裁管4の外径にさらに左右10mm程度プラスした寸法を目安とする。その形状は四角形でも円形でも差し支えない。この図では200φおよび100φの鞘管3と150φの半裁管4が設けられる場合を示す。
When constructing the formwork panel structure for the foundation, first, as shown in FIG. 2, attach it to the attachment position of the
次に、図3に示すように、取り付け穴6内に鞘管3や半裁管4などの連通管を片側から通して駆体内に貫通させる。このとき、図5、図6に示すように、連通管を梁幅Dより両面でのリブ部の高さ分と突出長さ分長く切断しておき、連通管の両端が型枠パネル1のリブ部の表面から両面で5mm程度外部に出るようにする。
Next, as shown in FIG. 3, a communicating tube such as the
次に、図4に示すように両側でカバープレート2に鞘管3や半裁管4などの連通管を通し、カバープレート2をビスで型枠パネル1に固定する。カバープレート2の板圧は例えば0.4mm程度であり、鞘管3の径とカバープレート2の穴径とカバープレート2の寸法の関係は例えば図7に示す通りである。
鞘管3として用いるパイプは、例えば50φから200φ位までのものを用意して状況に応じて使い分ける。鞘管径の細いものは配線や配管を通すに用いられ、太いものは人が通る人通孔としても用いられる。この例では50φから200φの鞘管径に対し、穴径は両サイドに7.5mmの隙間を置いて15mm増し、カバープレート2の寸法は100mm増しの正方形としている。半裁管4の場合もこれに準じた寸法、形状を採る。
Next, as shown in FIG. 4, communication pipes such as a
The pipe used as the
鞘管3や半裁管4などの連通管はカバープレート2の表面に粘着テープなどで仮止めした後、型枠パネル1間にコンクリートを打って躯体コンクリートを形成する。なお、鞘管3や半裁管4の切断面には、安全のために端面を覆う保護キャップ5を被せるようにしてもよい。
Communication pipes such as the
このように、本発明の型枠パネル構造体によれば、梁幅Dが分かっておれば、予め、それに応じた連通管パイプ部を構成しておくことができ、作業現場では連通管の取り付け位置に切断機を用いて取り付け穴6を開けたり、カバープレート2をビスで固定したりする程度の作業で連通管部分を含む型枠パネル構造体を構成することができるので、現場での作業が容易で結果的に廉価に作成することができる。
Thus, according to the formwork panel structure of the present invention, if the beam width D is known, a communication pipe portion corresponding to the beam width D can be configured in advance, and the connection pipe is attached at the work site. Formwork panel structure including the communication pipe part can be constructed by the work of opening the
本発明は、型枠パネルと連通管とからなる基礎用型枠パネル構造体を現場で容易に構成可能に実現したので、大きな規模から小さな規模の建築物の建設現場で広く用いることができ、広範囲な利用が見込め、産業上の利用可能性が高い。 Since the present invention has realized a foundation formwork panel structure composed of a formwork panel and a communication pipe so that it can be easily configured on site, it can be widely used in construction sites of buildings from large scales to small scales. Wide range of use is expected, and industrial applicability is high.
