Description

本発明は、コンクリート型枠に係り、特に型枠構成部材をコンクリートから容易に剥離することができるコンクリート型枠に関する。   The present invention relates to a concrete formwork, and more particularly to a concrete formwork capable of easily peeling a formwork component from concrete.

従来、この種の型枠は、底板部の周囲に枢着部により側板部を展開可能に枢着し、それら側板部相互を締め金具により固定して組立てた後、コンクリートを充填し、コンクリートの硬化後に締め金具を外し、側板部を展開して脱型し、コンクリート製品を成形するようにしている（例えば特許文献１及び特許文献２）。   Conventionally, this type of formwork is pivotally attached to the periphery of the bottom plate portion by a pivotally attached portion so that the side plate portion can be unfolded, and the side plate portions are fixed and assembled together with fasteners, and then filled with concrete. After curing, the fasteners are removed, the side plate portions are unfolded and removed to form a concrete product (for example, Patent Document 1 and Patent Document 2).

また、型枠には、コンクリートが硬化した後、側板部である外枠を外側にスライド移動させるようにして離すことにより脱型するものがある（例えば特許文献３）。   Further, some molds are demolded by releasing the outer frame which is a side plate part by sliding the outer frame after the concrete is hardened (for example, Patent Document 3).

上記のような型枠は、構造が比較的簡易で、量産用として優れた利点を有する。しかし、製品の形状が複雑になると、側板部にコンクリートが密着し、側板部に内面に剥離材を塗布しても、側板部を容易に展開又は離することができなくなり、生産性が大幅に低下する問題がある。
特開平１０−３３７７１６号公報 特開２００２−２４８６１４号公報 特開２００２−３２６２１３号公報 The above-mentioned formwork has a relatively simple structure and has excellent advantages for mass production. However, when the shape of the product becomes complicated, the concrete adheres to the side plate part, and even if a release material is applied to the inner side surface of the side plate part, the side plate part cannot be easily deployed or separated, which greatly increases productivity. There is a problem that decreases.

次に、前記構成につき、その作用を説明すると、型枠１を閉じた状態で、各充填空間９にコンクリートを充填し、このコンクリートが硬化したら、型開きを行う。ここで、まず、操作部34を操作して、押圧部23を型枠１内へと押し込んでやる。すると、硬化したコンクリート製品101が押圧部23により部分的に押され、コンクリート製品101と側板部４との間に僅かな隙間でき、両者の密着状態が解除され、この後は、側板部４を枢着部12Ａを中心として簡単に展開することができる。   Next, the operation of the above-described structure will be explained. Concrete is filled in each filling space 9 with the mold 1 closed, and when the concrete is hardened, the mold is opened. Here, first, the operating portion 34 is operated to push the pressing portion 23 into the mold 1. Then, the hardened concrete product 101 is partially pressed by the pressing portion 23, and a slight gap is formed between the concrete product 101 and the side plate portion 4, and the close contact state between both is released. It can be easily deployed around the pivoting part 12A.

このように本実施例では、請求項１に対応して、型枠構成部材たる側板部４内にコンクリートを充填し、コンクリートから側板部４を離してコンクリート製品101を成形するコンクリート型枠１において、側板部４に設けられコンクリート外面に接する押圧部23と、この押圧部23を側板部４の内側に移動する移動手段26とを備えるから、充填したコンクリートが硬化したら、移動手段26により押圧部23を内側に移動することにより、コンクリート製品101の外面と側板部４の内面との間に隙間ができ、この後、コンクリート製品101から側板部４を簡単に離すことができる。   As described above, in this embodiment, in the concrete mold 1 corresponding to the first aspect, the concrete is filled in the side plate portion 4 which is a mold frame constituting member, and the concrete plate 101 is formed by separating the side plate portion 4 from the concrete. And a pressing portion 23 provided on the side plate portion 4 and in contact with the concrete outer surface, and a moving means 26 for moving the pressing portion 23 to the inside of the side plate portion 4. By moving 23 inward, a gap is formed between the outer surface of the concrete product 101 and the inner surface of the side plate portion 4, and thereafter, the side plate portion 4 can be easily separated from the concrete product 101.

また、このように本実施例では、請求項２に対応して、押圧部23の内面23Ａが側板部４の内面と同一位置に固定可能であるから、コンクリート製品101の表面に与える影響が少ないものとなる。   In this way, in this embodiment, corresponding to claim 2, since the inner surface 23A of the pressing portion 23 can be fixed at the same position as the inner surface of the side plate portion 4, there is little influence on the surface of the concrete product 101. It will be a thing.

また、このように本実施例では、請求項３に対応して、複数の押圧部23，23…を設け、移動手段26は複数の押圧部23，23…を移動するから、押圧部23，23…を複数設けることにより、コンクリート外面から側板部４を均等且つ効率よく引き離すことができ、しかも、共通する移動手段26により簡便に操作することができる。   In this way, in the present embodiment, a plurality of pressing portions 23, 23... Are provided and the moving means 26 moves the plurality of pressing portions 23, 23. 23 is provided, the side plate portion 4 can be evenly and efficiently separated from the concrete outer surface, and can be easily operated by the common moving means 26.

Since the pressing portion 23 is provided on the side of the side plate portion 4 so that it can be unfolded by the landing portion 12A, the pressing portion 23 is provided on the side away from the pivoting portion 12A, and the insulator is centered on the pivoting portion 12A. With this principle, the separation effect due to the movement of the pressing portion 23 is excellent, and since it is close to the upper opening side, it is easy to separate.

また、実施例上の効果として、駆動杆27の移動方向に対して斜設された長孔29Ａと、これに係合する伝達ピン30とにより、駆動杆27の往復動をこれと交差する押圧部23の往復動に変換することにより、複数の押圧部23を確実に駆動することができる。   Further, as an effect on the embodiment, the reciprocating motion of the driving rod 27 is pressed by the long hole 29A obliquely provided with respect to the moving direction of the driving rod 27 and the transmission pin 30 engaged therewith. By converting the reciprocation of the portion 23, the plurality of pressing portions 23 can be reliably driven.

図７は本発明の実施例２を示し、上記実施例１と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では、剥離装置21の変形例を示し、作動杆25は単独で駆動し、前記側板部４の外側に案内筒体41を設け、案内筒体41は前記案内板33，33に固定され、これにより側板部４に固定されており、前記案内筒体41の内部に雌螺子部41Ａを形成し、この雌螺子部41Ａに螺合する雄螺子部25Ｂを、前記作動杆25に形成し、作動杆25の外端側に操作部たるバーハンドル42を挿通する。また、作動杆25の先端を、回動連結部25Ｃにより、前記押圧部23の補強板24に回動可能に連結する。さらに、作動杆25の先端側には前記案内板33に当接する内側ストッパ43が設けられ、前記内側ストッパ43が前記案内板33に当接した位置で、押圧部23の内面23Ａは側板部４の内面と面一となる。尚、前記作動杆25及び案内筒体41などにより移動手段26Ａを構成している。   FIG. 7 shows a second embodiment of the present invention. The same reference numerals are given to the same parts as those in the first embodiment, and detailed description thereof is omitted. In this example, a modification of the peeling device 21 is shown. The operating rod 25 is driven alone, and a guide cylinder 41 is provided outside the side plate portion 4, and the guide cylinder 41 is fixed to the guide plates 33 and 33, thereby being fixed to the side plate portion 4, A female screw portion 41A is formed inside the guide cylinder 41, and a male screw portion 25B that is screwed into the female screw portion 41A is formed in the operating rod 25, which is an operating portion on the outer end side of the operating rod 25. Insert the bar handle 42. Further, the distal end of the operating rod 25 is rotatably connected to the reinforcing plate 24 of the pressing portion 23 by the rotation connecting portion 25C. Further, an inner stopper 43 that abuts against the guide plate 33 is provided on the distal end side of the operating rod 25, and the inner surface 23 A of the pressing portion 23 is located on the side plate portion 4 at a position where the inner stopper 43 abuts against the guide plate 33. It will be flush with the inner surface. The operating rod 25, the guide cylinder 41, and the like constitute moving means 26A.

そして、押圧部23の内面23Ａが側板部４の内面と面一の状態で、型枠１内にコンクリートを充填し、このコンクリートが硬化したら、型開きを行う。ここで、まず、バーハンドル42を操作し、作動杆25と押圧部23とは回動連結部25Ｃにより連結されているから、作動杆25のみが回転し、押圧部23を内側へと押し付け、これにより硬化したコンクリート製品101が押圧部23により部分的に押され、コンクリート製品101と側板部４との間に僅かな隙間ができ、両者の密着状態が解除され、この後は、枢着部12Ａを中心として側板部４を簡単に展開することができる。   Then, with the inner surface 23A of the pressing portion 23 being flush with the inner surface of the side plate portion 4, the mold 1 is filled with concrete, and when the concrete is cured, the mold is opened. Here, first, the bar handle 42 is operated, and since the operating rod 25 and the pressing portion 23 are connected by the rotation connecting portion 25C, only the operating rod 25 rotates and presses the pressing portion 23 inward.
