Description

本発明は、型枠ユニットに係り、特に、コンクリートを打設して建物の基礎を形成するために用いられる型枠ユニットに関する。   The present invention relates to a formwork unit, and more particularly, to a formwork unit used for casting concrete to form a foundation of a building.

従来、建物の基礎工事において型枠ユニットが用いられている。
主な基礎工事の流れとしては、まず基礎が形成される部分の地盤を根切りし、根切りされた地盤に対して地耐力を確保すべく砕石を敷き詰めて固める。そして、床下からの湿気防止のため防湿フィルムを敷き込むと共に、基礎外周部において捨てコンクリートを打設して基礎配筋用の墨出しを行った上で、配筋作業を実施する。そして、基礎の形状に合わせて型枠を組み、基礎のベース部分に対しコンクリートを打設した後、さらに基礎内部の立ち上がり部分の型枠を組み、当該立ち上がり部分に対しコンクリートを打設する（当該型枠を組む際には建物の基礎と土台を繋ぐアンカーボルトを合わせて設置する）。そして、コンクリートの十分な養生期間を経た後、組み立てられた型枠を取り外すこととなる。
上記基礎工事において、作業者による作業性の効率を上げるべく、型枠ユニットの形状、構成を工夫したものが知られている（例えば、特許文献１、２参照）。 2. Description of the Related Art Conventionally, formwork units have been used in foundation work of buildings.
As the main foundation work flow, the ground where the foundation is formed is first cut off, and crushed stones are spread and hardened to secure the soil resistance to the cut ground. Then, a moisture-proof film is laid to prevent moisture from under the floor, and at the outer periphery of the foundation, discarded concrete is cast to perform marking for foundation reinforcement, and then a reinforcement operation is performed. Then, after assembling the formwork according to the shape of the foundation and placing concrete in the base portion of the foundation, further assembling the formwork of the rising portion inside the foundation, and placing concrete in the rising portion (such as When assembling the formwork, install the anchor bolts that connect the foundation and base of the building together.) Then, after a sufficient curing period of the concrete, the assembled formwork is removed.
In the above-mentioned foundation work, there is known one in which the shape and configuration of a form unit are devised in order to increase the efficiency of workability by an operator (for example, see Patent Documents 1 and 2).

特許文献１に記載の型枠ユニットでは、コンクリートを打設した後に型枠ユニットを容易に取り外すことを目的として、隣り合う型枠同士の当接面が斜めになるように型枠を組み立てる構成が開示されている。詳しく言うと、組み立てられた型枠同士を上面から見たときに、当該当接面が、従来は型枠の幅方向に沿って真っ直ぐに延びているところ、型枠の幅方向に対して傾斜する方向に沿って延びている。
上記構成により、当接面において摩擦を軽減することができ、組み立てられた型枠を当該型枠の幅方向外側へ引っ張ることで、当該型枠を容易に取り外すことができる。 In the form unit described in Patent Literature 1, for the purpose of easily removing the form unit after placing concrete, the form is assembled such that the contact surfaces of adjacent form forms are inclined. It has been disclosed. More specifically, when the assembled molds are viewed from the top, the abutting surface is conventionally extending straight along the width direction of the mold, but is inclined with respect to the width direction of the mold. Extending along the direction of
With the above configuration, friction can be reduced at the contact surface, and the assembled form can be easily removed by pulling the assembled form outward in the width direction of the form.

特許文献２に記載の型枠の建て込み方法においても、隣り合う型枠同士が傾斜面を有し、互いの傾斜面を当接させて型枠全体を組み立てる構成が開示されており、組み立てられた型枠を幅方向の外側へ引っ張るときに打設コンクリートから剥離し易くしている。   Also in the method of installing a form described in Patent Document 2, there is disclosed a configuration in which adjacent molds have inclined surfaces, and the inclined surfaces are brought into contact with each other to assemble the entire form. When the formwork is pulled outward in the width direction, it is easy to peel off the cast concrete.

ところで、狭小地に建てられる狭小住宅のように、隣の建物との距離が例えば３０〜５０ｃｍ程度しかないような狭小地において建物を建築する場合には、作業者による基礎工事において型枠の取り外し作業が困難になることがある。
詳しく言うと、通常の作業者は、組み立てられた型枠を当該型枠の幅方向外側へ引っ張ることで、当該型枠を真横に倒して取り外しているところ、上記のような狭小地においては、作業者が型枠を真横に倒すことが可能なスペースが十分に確保できない場合が生じていた。
上記の場合には、特許文献１や特許文献２のような型枠ユニットをそのまま採用することができないため、作業者が現場レベルで特殊な工具や治具を別途使用する等して対応していた。 By the way, when building a building on a narrow land where the distance to an adjacent building is only about 30 to 50 cm, such as a small house built on a narrow land, a worker removes the formwork in the foundation work. Work may be difficult.
More specifically, a normal worker pulls the assembled formwork to the outside in the width direction of the formwork to remove the formwork sideways, and in a narrow space as described above, There has been a case where a sufficient space for an operator to fall the formwork to the side cannot be sufficiently secured.
In the above case, since the mold unit as in Patent Literature 1 or Patent Literature 2 cannot be employed as it is, a worker uses a special tool or jig separately at the site level to cope with the situation. Was.

本発明は、上記の課題に鑑みてなされたものであり、本発明の目的は、隣の建物と接近して建築される建物の基礎工事の場合であっても、作業者の負担を軽減することが可能な型枠ユニットを提供することにある。
また、本発明の他の目的は、建物の基礎工事において組み立てられた型枠を容易に取り外すことが可能な型枠ユニットを提供することにある。 The present invention has been made in view of the above-described problems, and an object of the present invention is to reduce the burden on the worker even in the case of foundation work of a building constructed close to an adjacent building. It is an object of the present invention to provide a mold unit capable of performing the above steps.
It is another object of the present invention to provide a form unit capable of easily removing a form assembled in foundation work of a building.

前記課題は、本発明の型枠ユニットによれば、コンクリートを打設して建物の基礎を形成するために用いられる型枠ユニットであって、それぞれ隣り合うように配置され、水平方向において互いに当接している第１型枠及び第２型枠と、前記第１型枠に対して前記第２型枠側とは反対側の位置に配置され、水平方向において前記第１型枠に当接している第３型枠と、を備え、前記第１型枠において、前記第２型枠に当接する第１当接部と、前記第３型枠に当接する第２当接部とのうち一方の当接面が、前記第１型枠の下方から上方へ向かうに従って他方の当接面から離れるように傾斜して延びていること、により解決される。
上記構成により、隣の建物と接近して建築される建物の基礎工事の場合であっても、作業者の負担を軽減することが可能な型枠ユニットを実現することができる。
詳しく説明すると、本発明の型枠ユニットであれば、作業者が第１型枠を上方へ引っ張って取り外すときに第１型枠にかかる摩擦を軽減することができ、第１型枠を容易に取り外すことができる。また、従来のように、作業者が第１型枠を真横に倒して取り外す必要がないため、狭小地において十分な幅スペースが確保できない場合であっても、作業者が型枠の取外し作業を効率良く実施することができる。 According to the formwork unit of the present invention, the above-mentioned object is a formwork unit which is used for casting concrete to form a foundation of a building, and is arranged adjacent to each other, and is in contact with each other in a horizontal direction. The first mold and the second mold that are in contact with each other, and the second mold and the first mold are arranged at positions opposite to each other with respect to the first mold, and contact with the first mold in a horizontal direction. And a third abutment that contacts the second form, and a second abutment that contacts the third form. This problem is solved by that the contact surface extends obliquely away from the other contact surface as going upward from below the first formwork.
With the above configuration, it is possible to realize a formwork unit capable of reducing the burden on an operator even in the case of foundation work of a building constructed close to an adjacent building.
More specifically, the formwork unit of the present invention can reduce friction applied to the first formwork when an operator pulls the first formwork upward to remove the formwork, so that the first formwork can be easily performed. Can be removed. Further, unlike the related art, the worker does not need to lay the first formwork sideways to remove the formwork. Therefore, even when a sufficient width space cannot be secured in a small area, the worker can perform the work of removing the formwork. It can be implemented efficiently.

このとき、前記第１当接部と前記第２当接部との双方の当接面が、前記第１型枠の下端部から上端部まで向かうに従って互いに離れるように延びており、かつ、上下方向に対して傾斜する方向に延びていると良い。
上記構成により、作業者が第１型枠を上方へ引っ張って取り外すときに第１型枠にかかる摩擦を一層軽減することができ、第１型枠を一層容易に取り外すことができる。 At this time, both contact surfaces of the first contact portion and the second contact portion extend away from each other from the lower end to the upper end of the first formwork, and It is preferable to extend in a direction inclined with respect to the direction.
According to the above configuration, when the operator pulls the first formwork upward to remove it, the friction on the first formwork can be further reduced, and the first formwork can be more easily removed.

このとき、前記第１型枠よりも上方に配置され、複数並べられた型枠の上面に沿って延びている延出部材と、前記第１型枠と前記延出部材を連結し、前記第１型枠に対して前記延出部材の高さ位置を変更可能な状態で取り付けられる高さ調整部材と、前記第１型枠と前記延出部材の上下方向の間に隙間を形成するために、前記延出部材と、前記第２型枠及び前記第３型枠それぞれとの間に配置される中間部材と、を備えていると良い。
また、前記高さ調整部材は、前記第１型枠のうち前記第１当接部と前記第２当接部の間の中央位置に配置され、かつ、前記第２型枠及び前記第３型枠それぞれの上面に配置される前記中間部材の間の中央位置に配置されていると良い。
上記構成により、第１型枠に対する延出部材の高さ位置を低くするように高さ調整部材を用いて調整することで、第２型枠及び第３型枠を支点として第１型枠に対し上方向の反力が生じるため、第１型枠が第２型枠及び第３型枠に対して浮き上がる又は浮き上がり易くなる。従って、作業者が高さ調整部材を利用しながら第１型枠を上方へ引っ張ることで、第１型枠を一層容易に取り外すことができる。 At this time, an extending member arranged above the first mold and extending along the upper surface of the plurality of arranged molds, and connecting the first mold and the extending member, A height adjusting member attached to the first form such that the height of the extending member can be changed; and a gap between the first mold and the extending member in a vertical direction. , The extension member, and an intermediate member disposed between the second mold frame and the third mold frame.
The height adjusting member is disposed at a central position between the first contact portion and the second contact portion of the first mold, and the height adjusting member is provided at the center of the second mold and the third mold. It is good to be arrange | positioned in the center position between the said intermediate members arrange | positioned on the upper surface of each frame.
According to the above configuration, by adjusting the height of the extending member with respect to the first mold using the height adjusting member, the first and second molds are supported by the second and third molds. On the other hand, since an upward reaction force is generated, the first mold is lifted or easily lifted with respect to the second mold and the third mold. Therefore, the first mold can be more easily removed by the operator pulling the first mold upward while using the height adjusting member.

このとき、前記第１型枠のうち前記第１当接部に取り付けられ、前記第１型枠に対して前記第２型枠を着脱可能となるように連結する連結部材と、該連結部材と接続され、前記第１型枠よりも上方位置において前記連結部材の連結状態を解除するために操作される操作部を有する連結解除部材と、を備えていると良い。
また、前記連結解除部材は、長尺な弾性部材であって、前記連結解除部材は、前記連結部材に対して取り付けられる末端部と、前記第１型枠よりも上方位置に張り出すように配置される先端部と、を有し、前記操作部は、前記弾性部材のうち、前記第１型枠よりも上方位置に張り出した前記先端部側の位置に設けられていると良い。
上記構成により、型枠同士を連結部材で強固に連結することができるだけでなく、連結された型枠同士の連結状態を解除する際には、型枠よりも上方位置にある連結解除部材の操作部を操作すれば良いため、狭小地における建物の基礎工事においては、作業者による型枠取外し作業の効率性が格段に向上する。 At this time, a connecting member attached to the first contact portion of the first formwork and connecting the second formwork to the first formwork so as to be detachable, And a connection release member having an operation portion that is connected and that is operated to release the connection state of the connection member at a position above the first formwork.
Further, the connection releasing member is a long elastic member, and the connection releasing member is disposed so as to protrude to a position above the first mold and a distal end attached to the connection member. And the operating portion is preferably provided at a position on the side of the distal end portion of the elastic member that protrudes above the first mold frame.
With the above configuration, not only can the formwork be firmly connected by the connecting member, but also when releasing the connected state of the connected formwork, the operation of the connection release member located above the formwork is required. Since the parts may be operated, the efficiency of the work of removing the formwork by the worker is greatly improved in the foundation work of the building on the narrow land.

本発明の型枠ユニットによれば、隣の建物と接近して建築される建物の基礎工事の場合であっても、作業者の負担を軽減することが可能となる。
また、建物の基礎工事において組み立てられた型枠を容易に取り外すことが可能となる。 ADVANTAGE OF THE INVENTION According to the formwork unit of this invention, even in the case of the foundation work of the building constructed close to an adjacent building, it becomes possible to reduce a burden of an operator.
Further, the formwork assembled in the foundation work of the building can be easily removed.

In addition, these molds 10 may further include a rectangular plate-shaped reinforcement 17 in addition to the reinforcement 16 having a substantially convex cross-section, like the second mold 10b. In this case, it is preferable that the reinforcing portions 16 and the reinforcing portions 17 are arranged at predetermined intervals, as in the second mold 10b.

連結部材２０は、図３、図４に示すように、型枠１０の第１当接部１４及び第２当接部１５それぞれに取り付けられ、隣り合う型枠１０同士を連結するための連結金具であって、上下方向に所定の間隔を空けて複数取り付けられている。
具体的には、連結部材２０は、隣り合う型枠１０同士の当接部分にそれぞれ形成された不図示の挿通穴に挿通可能となるように設けられたベース軸部２１と、ベース軸部２１の表面から連続してベース軸部２１の軸方向とは交差する方向に延出し、型枠１０同士の当接部分を挟み込むように設けられたフック形状のクリップ部２２と、を有している。
連結部材２０は、ベース軸部２１を中心軸としてクリップ部２２を回転可能となるように構成されている。
そのため、連結部材２０は、クリップ部２２を回転移動させることで、型枠１０同士を連結した連結状態と、型枠１０同士の連結状態を解除した解除状態との間で切り替えることができる。
ベース軸部２１の一端部には、図４に示すように、連結解除部材３０が取り付けられている。 As shown in FIGS. 3 and 4, the connection member 20 is attached to each of the first contact portion 14 and the second contact portion 15 of the mold 10, and is a connection fitting for connecting adjacent molds 10. And a plurality of them are attached at predetermined intervals in the vertical direction.
Specifically, the connecting member 20 includes a base shaft portion 21 provided so as to be able to be inserted into an insertion hole (not shown) formed in a contact portion between the adjacent mold frames 10, and a base shaft portion 21. And a hook-shaped clip portion 22 which extends continuously from the surface of the base shaft portion 21 in a direction intersecting with the axial direction of the base shaft portion 21 and is provided so as to sandwich the contact portion between the mold frames 10. .
The connecting member 20 is configured to be able to rotate the clip portion 22 about the base shaft portion 21 as a central axis.
Therefore, the connecting member 20 can switch between the connected state in which the molds 10 are connected to each other and the released state in which the connected state of the molds 10 is released by rotating the clip portion 22.
As shown in FIG. 4, a connection release member 30 is attached to one end of the base shaft portion 21.

連結解除部材３０は、図４に示すように、長尺な弾性バンド（弾性部材）であって、連結部材２０の軸方向の一端部に取り付けられる末端部３１と、末端部３１から連続して上方へ延出し、型枠１０の上壁部１２に設けられた挿通穴１２ｂを通過して型枠１０よりも上方位置に張り出すように延びている先端部３２と、を有している。
また、連結解除部材３０は、型枠１０よりも上方位置に張り出した先端部３２側の位置において、連結部材２０の連結状態を解除するために操作される操作部３３を有している。 The connection releasing member 30 is a long elastic band (elastic member) as shown in FIG. A tip portion 32 extending upward and passing through an insertion hole 12b provided in the upper wall portion 12 of the mold 10 and extending to a position higher than the mold 10;
Further, the connection release member 30 has an operation unit 33 that is operated to release the connection state of the connection member 20 at a position on the side of the distal end portion 32 protruding above the formwork 10.

上記構成において、連結部材２０の連結状態を解除するためには、作業者が操作部３３を把持して連結解除部材３０を上下方向に揺らすことで、連結部材２０に振動が伝わり、当該振動に伴って連結部材２０のクリップ部２２が回転移動する。その結果、連結部材２０の連結状態が解除されることとなる。
そのため、特に狭小地における建物の基礎工事においては、作業者による型枠取外し作業の効率性が格段に向上する。 In the above-described configuration, in order to release the connection state of the connection member 20, vibration is transmitted to the connection member 20 by the operator holding the operation unit 33 and swinging the connection release member 30 in the vertical direction, and the vibration is transmitted to the connection member 20. Accordingly, the clip portion 22 of the connecting member 20 rotates. As a result, the connection state of the connection member 20 is released.
Therefore, especially in the foundation work of a building in a narrow land, the efficiency of the formwork removal work by the worker is remarkably improved.

延出部材４０は、図５に示すように、断面略Ｌ字形状の長尺な板状部材であって、型枠１０（第１型枠１０ａ）の上壁部１２に対して高さ調整部材５０を介して組み付けられている。
また延出部材４０は、第１型枠１０ａの両隣にある第２型枠１０ｂ及び第３型枠１０ｃそれぞれの上面に載置された矩形板状の中間部材６０によって下方から支持されている。
高さ調整部材５０は、第１型枠１０ａの上壁部１２に設けられた締結穴１２ａを通じて下方から組み付けられる固定ボルト５１と、固定ボルト５１の軸部分に対して螺合される高さ調整ナット５２と、を有している。
高さ調整部材５０は、上下方向において第１型枠１０ａの上壁部１２及び延出部材４０を挟み込むように設けられており、高さ調整ナット５２の螺合位置を調整することで、延出部材４０の高さ位置を変更可能となるように構成されている。
なお、高さ調整部材５０は、第１型枠１０ａのうち第１当接部１４と第２当接部１５の間の中央位置に配置され、かつ、第２型枠１０ｂ及び第３型枠１０ｃそれぞれの上面に配置される中間部材６０の間の中央位置に配置されている。 As shown in FIG. 5, the extending member 40 is a long plate-like member having a substantially L-shaped cross section, and the height of the extending member 40 is adjusted with respect to the upper wall portion 12 of the mold 10 (first mold 10 a). It is assembled via a member 50.
The extending member 40 is supported from below by a rectangular plate-shaped intermediate member 60 placed on the upper surface of each of the second mold frame 10b and the third mold frame 10c on both sides of the first mold frame 10a.
The height adjusting member 50 has a fixing bolt 51 that is assembled from below through a fastening hole 12a provided in the upper wall portion 12 of the first mold frame 10a, and a height adjustment screwed to a shaft portion of the fixing bolt 51. And a nut 52.
The height adjusting member 50 is provided so as to sandwich the upper wall portion 12 and the extending member 40 of the first mold 10a in the vertical direction, and the height adjusting member 50 adjusts the screwing position of the height adjusting nut 52 to extend the height. The height position of the output member 40 is configured to be changeable.
The height adjusting member 50 is disposed at a central position between the first contact portion 14 and the second contact portion 15 in the first mold frame 10a, and the second mold frame 10b and the third mold frame are provided. 10c are arranged at a central position between the intermediate members 60 arranged on the respective upper surfaces.

上記構成において、第１型枠１０ａに対する延出部材４０の高さ位置を低くするように高さ調整ナット５２の螺合位置を調整することで、第２型枠１０ｂ及び第３型枠１０ｃ上の中間部材６０を支点として第１型枠１０ａに対し上方向の反力が生じることになる。
その結果、第１型枠１０ａが第２型枠１０ｂ及び第３型枠１０ｃに対して浮き上がる又は浮き上がり易くなる。
従って、作業者が高さ調整部材５０を利用しながら第１型枠１０ａを上方へ引っ張ることで、第１型枠１０ａを一層容易に取り外すことが可能となる。 In the above configuration, by adjusting the screwing position of the height adjusting nut 52 so as to lower the height position of the extending member 40 with respect to the first mold frame 10a, the second mold frame 10b and the third mold frame 10c can be adjusted. With the intermediate member 60 as a fulcrum, an upward reaction force is generated against the first mold 10a.
As a result, the first mold 10a rises or easily rises with respect to the second mold 10b and the third mold 10c.
Therefore, when the operator pulls the first mold 10a upward while using the height adjusting member 50, the first mold 10a can be more easily removed.
