Abstract

PROBLEM TO BE SOLVED: To easily and reliably connect two round steel materials and thereby prevent the two round steel materials from coming off.SOLUTION: A separator for a form comprises: a cylindrical body having through holes capable of loosely inserting the two round steel materials thereto in a contact state; and a hole that is opened in the cylindrical body so that a wedge can be driven into a void between the two round steel materials that are inserted into the cylindrical body. In addition, the cylindrical body has a shape in which an inner diameter of a central part is slightly larger than that of an opening. Furthermore, the wedge has a polyhedral shape and a sharp apex angle at a ridge part.

Description

本発明は、コンクリートの型枠を固定するためのセパレータに関する。   The present invention relates to a separator for fixing a concrete formwork.

従来のセパレータとしては、図３に示すように２本の丸鋼材を挿通する貫通孔１１ａを設けた筒状の連結金具１１に２本の丸鋼材１２と１２をぞれぞれ並列に挿通し、その丸鋼材の隙間に鋭角状の食い込み緑が形成された楔１３を圧入、押圧して連結固定するものがある。
実公平７−５１５６号公報 特開平１１−２２３０１７号公報 As a conventional separator, as shown in FIG. 3, two round steel members 12 and 12 are inserted in parallel through a cylindrical connecting metal fitting 11 provided with a through hole 11a for inserting two round steel members. In some cases, a wedge 13 having a sharp-angled bite green is pressed into and pressed between the round steel members to be connected and fixed.
No. 7-5156 JP-A-11-2223017

しかし、従来例のセパレータにあっては、筒体の内経が全長にわたって同一となっているので、丸鋼材が湾曲するスペースを確保することができない。このため楔１３は単に筒体内壁、丸鋼材の押圧に終わり連結強度が落ちるという問題点がある。   However, in the conventional separator, the inner diameter of the cylindrical body is the same over the entire length, so that it is not possible to secure a space where the round steel material is curved. For this reason, the wedge 13 has a problem that the connection strength is lowered only after the inner wall of the cylinder and the round steel material are pressed.

この発明が提供する型枠のセパレータは、従来のこのような問題点を解決するためになされたもので、２本の丸鋼材を接触状態に遊挿できる貫通孔を有する筒体と、筒体に通した２本の丸鋼材の隙間に楔の打ち込みを可能にする同筒体に開けた穴とより構成し、かつ、
前記筒体は、その中央部の内経を
開口部のそれよりやや大きくした形状としたものである。また、前記楔は、多面体で陵部の頂角が鋭利となっている形状としたものである。 The separator of the formwork provided by the present invention has been made in order to solve such a conventional problem, and a cylindrical body having a through-hole capable of loosely inserting two round steel materials into a contact state, and a cylindrical body A hole formed in the cylindrical body that allows a wedge to be driven into a gap between two round steel materials passed through
The cylindrical body has a shape in which the inner diameter of the central portion is slightly larger than that of the opening. The wedge is a polyhedron and has a shape in which the apex angle of the ridge is sharp.

上術したように、本発明の型枠のセパレータは、筒体の中央部の内経をやや大きくして膨らみをもたせた形状としたので、丸鋼材の側面と筒体の内壁との間に丸鋼材の湾曲が可能となるスペースを確保することができる。このため、楔を打ち込まれた丸鋼材は筒体に対して直交方向に押圧されて湾曲し、確実に固定されて抜けなくなる。また、前記楔は、多面体で陵部の頂角が鋭利な形状となっているので、頂部が丸鋼材に食い込み両丸鋼材の互いの反対方向への引張力は楔の回転運動となる。このため、筒体内壁への強力な押圧となって更に丸鋼材は抜けにくくなり、格段に連結強度が増す。   As described above, the separator of the formwork according to the present invention has a shape in which the inner diameter of the central portion of the cylindrical body is slightly enlarged and has a bulge, so that it is between the side surface of the round steel material and the inner wall of the cylindrical body. A space where the round steel material can be bent can be secured. For this reason, the round steel material into which the wedge is driven is pressed in a direction orthogonal to the cylindrical body and curved, and is securely fixed and cannot be removed. Further, since the wedge is a polyhedron and has a shape with a sharp apex angle of the ridge, the top bites into the round steel material, and the tensile force in the opposite directions of both round steel materials is the rotational motion of the wedge. For this reason, it becomes a strong press to the wall in a cylinder, and it becomes difficult to remove a round steel material further, and connection strength increases remarkably.

また、楔への打撃という単純な作業で迅速、確実、且つ間単に連結することができるので、作業効率は格段に向上する。更に、構造、構成がシンプルであるためにいかなる連結金具より安価に製造できれば利用者側からも大いに期待がもてる。そして、構造物に取り付けながらの連結については、楔の打ち込み工具を開発すればよく、更に利用価値は拡大すると思われる。   Further, since the connection can be made quickly, reliably and simply by a simple operation of hitting the wedge, the work efficiency is remarkably improved. Furthermore, since the structure and configuration are simple, users can expect much if they can be manufactured at a lower cost than any connecting bracket. For connection while being attached to the structure, a wedge driving tool may be developed, and the utility value is expected to further increase.

以下、この発明の実施の形態を実施例にもとづき図面を参照して説明する。
この型枠のセパレータは、筒体１、２本の丸鋼材２，２、楔３とから構成され、連結セパレータの作成を臨機に対応するために用いるものである。
図１は、筒体に丸鋼材２と２はそれぞれ反対方向から筒体１の開口部１ａより挿通されて接触状態が保たれている。そして楔３は、２本の丸鋼材の隙間に打ち込む部品であって、隙部の頂角３ａが鋭利となっている。１ｂは、楔の打ち込み穴で筒体の両面に開けられている。 Embodiments of the present invention will be described below with reference to the drawings based on examples.
The separator of this mold is composed of a cylindrical body 1, two round steel materials 2, 2, and a wedge 3, and is used to respond to the creation of a connected separator.
In FIG. 1, the round steel materials 2 and 2 are inserted into the cylindrical body from the opposite directions from the opening 1 a of the cylindrical body 1 so that the contact state is maintained. The wedge 3 is a part that is driven into the gap between the two round steel materials, and the apex angle 3a of the gap is sharp. 1b is opened on both surfaces of the cylindrical body by a driving hole of a wedge.

図２は、筒体１に挿通した２本の丸鋼材２と２の隙間に楔穴１ｂより楔３が打ち込まれた状態を表わしている。また、この楔は陵部の頂角が鋭利な突起３ａが形成されているので、突起が丸鋼材に食い込んだ状態となっている。   FIG. 2 shows a state in which the wedge 3 is driven into the gap between the two round steel members 2 and 2 inserted through the cylindrical body 1 through the wedge hole 1b. Further, since this wedge is formed with a protrusion 3a having a sharp apex angle at the ridge, the protrusion is in a state of biting into the round steel material.
