Abstract

PROBLEM TO BE SOLVED: To provide a concrete formwork which does not need removal of a formwork material, and which does not need disassembly and removal of members for supporting the formwork material.SOLUTION: A concrete structure is formed by casting concrete into a formwork part 5 formed by each concrete board 1 and each concrete board 1 is left to be integrated with a concrete structure so that it is unnecessary to remove the formwork material after concrete hardening and it is not also unnecessary to disassemble or remove complicated members for supporting the formwork material. In this case, since the concrete boards 1 are fixed to each other by connecting separators 2 of the concrete boards 1 by respective connecting members 3 and 4, it is unnecessary to directly fix the concrete boards 1 to each other. Furthermore, since the separators 2 are connected to each other inside the formwork part 5 by the respective connecting members 3 and 4, the connecting members 3 and 4 are not exposed to the outside of the formwork part 5.SELECTED DRAWING: Figure 1

Description

本発明は、例えば一般家屋、マンション、オフィスビル等のコンクリート建築において、コンクリート製の型枠材を残置してコンクリート構造物と一体化するようにしたコンクリート型枠に関するものである。   The present invention relates to a concrete formwork in which concrete formwork material is left and integrated with a concrete structure in a concrete building such as a general house, a condominium, and an office building.

一般に、コンクリート建築の施工においては、木製の型枠材をセパレータによって厚さ方向に間隔をおいて保持するとともに、型枠内にコンクリートを打設し、養生期間経過後に型枠を撤去するようにしている。   In general, in concrete construction work, wooden formwork materials are held at intervals in the thickness direction by separators, and concrete is placed in the formwork, and the formwork is removed after the curing period has elapsed. ing.

しかしながら、このように木製の型枠材を用いる場合は、コンクリート硬化後に型枠を解体し、型枠材を撤去する必要があるため、現場作業が繁雑になるとともに、自然保護の面からも木製の型枠材を使わない工法が望まれている。   However, when using wooden formwork in this way, it is necessary to dismantle the formwork after the concrete has hardened and remove the formwork. The construction method that does not use the formwork material is desired.

そこで、木製の型枠材の代わりにコンクリート製の型枠材を用いるとともに、コンクリート打設後も型枠材を残置してコンクリート構造物と一体化するようにしたコンクリート型枠が知られている（例えば、特許文献１参照。）。   Therefore, a concrete formwork is known in which a concrete formwork is used instead of a wooden formwork, and the formwork is left to be integrated with the concrete structure after the concrete is placed. (For example, refer to Patent Document 1).

このコンクリート型枠によれば、コンクリート打設後に型枠材を残置するようにしているので、木製の型枠材のように撤去する必要がなく、現場作業の省力化を図ることができるとともに、木材を使用しないので、自然保護の面からも好ましいという利点がある。   According to this concrete formwork, since the formwork material is left behind after placing the concrete, it is not necessary to remove it like a wooden formwork material, and it is possible to save labor on site work, Since wood is not used, there is an advantage that it is preferable from the viewpoint of nature protection.

実開平６−７３２０２号公報Japanese Utility Model Publication No. 6-73202

しかしながら、前述のようにコンクリート製の型枠材を用いる場合でも、型枠材をセパレータによって間隔をおいて保持するとともに、型枠全体を支持するための支保工を必要とする。このため、コンクリート硬化後、型枠は残置されるものの、支保工を解体及び撤去する必要があるが、支保工は根太、大引、支柱等の多数の複雑な部材からなるため、支保工の解体及び撤去作業に手間を要する分、現場作業の省力化を十分に図ることができないという問題点があった。   However, even when a concrete formwork material is used as described above, it is necessary to hold the formwork material at intervals with a separator and to support the entire formwork. For this reason, after the concrete is hardened, the formwork remains, but the support work needs to be dismantled and removed, but the support work is made up of many complex members such as joists, large pulls, and struts. There was a problem that the labor-saving of the field work could not be sufficiently achieved due to the time required for dismantling and removal work.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、型枠材の撤去が不要であるとともに、型枠材を支持するための部材の解体及び撤去の必要もないコンクリート型枠を提供することにある。   The present invention has been made in view of the above problems, and the object of the present invention is not to remove the formwork material, and it is not necessary to disassemble and remove the member for supporting the formwork material. It is to provide a concrete formwork.

本発明は前記目的を達成するために、複数のコンクリート板を互いに端面同士が当接するように配列するとともに、互いに厚さ方向に対向するコンクリート板同士をセパレータによって対向方向に間隔をおいて保持することにより型枠部を形成し、型枠部内にコンクリートを打設することによりコンクリート構造物を形成し、各コンクリート板を残置してコンクリート構造物と一体化するようにしたコンクリート型枠において、互いに前記配列方向に隣り合うコンクリート板のセパレータ同士を前記型枠部の内部で連結する連結部材を備えている。   In order to achieve the above object, the present invention arranges a plurality of concrete plates so that their end faces are in contact with each other, and holds the concrete plates facing each other in the thickness direction at intervals in the facing direction by a separator. In the concrete formwork in which the formwork part is formed, the concrete structure is formed by placing concrete in the formwork part, and each concrete plate is left and integrated with the concrete structure. There is provided a connecting member for connecting separators of concrete plates adjacent to each other in the arrangement direction inside the mold part.

これにより、各コンクリート板によって形成される型枠部内にコンクリートを打設することによりコンクリート構造物が形成されるとともに、各コンクリート板が残置されてコンクリート構造物と一体化されることから、従来のようなコンクリート硬化後における型枠材の撤去が不要であるとともに、型枠材を支持するための複雑な部材の解体及び撤去も必要としない。この場合、互いに隣り合うコンクリート板のセパレータ同士を連結部材によって連結することにより、コンクリート板同士が固定されることから、コンクリート板同士を直接固定する必要がない。また、セパレータ同士が連結部材によって型枠部内部で連結されることから、各連結部材が型枠部の外部に露出することがない。   As a result, a concrete structure is formed by placing concrete in a mold part formed by each concrete plate, and each concrete plate is left and integrated with the concrete structure. It is not necessary to remove the mold material after the concrete is hardened, and it is not necessary to disassemble and remove a complicated member for supporting the mold material. In this case, since the concrete plates are fixed by connecting the separators of the concrete plates adjacent to each other by the connecting member, it is not necessary to fix the concrete plates directly. Further, since the separators are connected to each other inside the mold part by the connecting member, each connecting member is not exposed to the outside of the mold part.

本発明によれば、コンクリート硬化後における型枠材の撤去が不要であるとともに、型枠材を支持するための複雑な部材の解体及び撤去も必要とすることがなく、現場作業の省力化を十分に図ることができる。この場合、コンクリート板同士を直接固定する必要がないので、コンクリート板同士を直接固定するための加工をコンクリート板に施す必要がなく、コンクリート板の構造を簡素化することができる。更に、セパレータ同士を連結する連結部材が型枠部の外部に露出することがないので、連結部材の露出によってコンクリート構造物の外観が損なわれることがないという利点もある。   According to the present invention, it is not necessary to remove the formwork material after the concrete is hardened, and it is not necessary to dismantle and remove a complicated member for supporting the formwork material. We can plan enough. In this case, since it is not necessary to directly fix the concrete plates, it is not necessary to apply the processing for directly fixing the concrete plates to the concrete plate, and the structure of the concrete plate can be simplified. Furthermore, since the connecting member for connecting the separators is not exposed to the outside of the mold part, there is an advantage that the appearance of the concrete structure is not impaired by the exposure of the connecting member.

図１乃至図９は本発明の第１の実施形態を示すもので、型枠部を形成するコンクリート板を残置してコンクリート構造物と一体化するようにしたコンクリート型枠を示すものである。   1 to 9 show a first embodiment of the present invention, which shows a concrete formwork in which a concrete plate forming a formwork portion is left and integrated with a concrete structure.

同図に示すコンクリート型枠は、互いに端面同士が当接するように上下左右に配列される複数のコンクリート板１と、コンクリート板１を厚さ方向に間隔をおいて保持するセパレータ２と、互いに隣り合う４つのコンクリート板１の４つのセパレータ２同士を連結する第１の連結部材３と、互いに隣り合う２つのコンクリート板１の２つのセパレータ２同士を連結する第２の連結部材４とを備えている。   The concrete form shown in the figure is adjacent to a plurality of concrete plates 1 arranged vertically and horizontally so that the end surfaces abut against each other, and a separator 2 that holds the concrete plates 1 at intervals in the thickness direction. A first connecting member 3 that connects the four separators 2 of the four matching concrete plates 1, and a second connecting member 4 that connects the two separators 2 of the two adjacent concrete plates 1. Yes.

コンクリート板１は、予め工場等で成形された板状のコンクリートからなり、例えば横長の四角形状に形成されている。コンクリート板１の四隅にはセパレータ２を固定する埋込ナット１ａが設けられ、各埋込ナット１ａは一端面がコンクリート板１の厚さ方向一方の面に露出するようにコンクリート板１に埋設されている。   The concrete plate 1 is made of plate-like concrete molded in advance at a factory or the like, and is formed in, for example, a horizontally long rectangular shape. Embedded nuts 1a for fixing the separator 2 are provided at the four corners of the concrete plate 1, and each embedded nut 1a is embedded in the concrete plate 1 so that one end surface is exposed on one surface in the thickness direction of the concrete plate 1. ing.

セパレータ２は、互いに対向して配置されるコンクリート板１に一端をそれぞれ固定された一対のシャフト２ａと、各シャフト２ａの軸方向の間隔を調整する間隔調整部材２ｂとからなり、間隔調整部材２ｂを各シャフト２ａに対して回動することにより、各シャフト２ａが軸方向に接近または離間するようになっている。シャフト２ａは、外周面にネジ部を有するボールネジからなり、その一端はコンクリート板１の埋込ナット１ａに螺合している。この場合、各シャフト２ａは、各シャフト２ａに螺合する第１の固定ナット２ｃを埋込ナット１ａに当接させて締め込むことによりコンクリート板１に固定される。間隔調整部材２ｂは、内周面にネジ部を有する円筒状の部材からなり、その両端側は各シャフト２ａの他端側にそれぞれ螺合している。この場合、図４に示すように間隔調整部材２ｂの軸方向一端側のネジ部２ｂ−１と軸方向他端側のネジ部２ｂ−２は互いに螺旋の向きが反対になっており、間隔調整部材２ｂを回動すると、各シャフト２ａが互いに軸方向反対方向に向かって移動するようになっている。   The separator 2 includes a pair of shafts 2a each having one end fixed to a concrete plate 1 disposed opposite to each other, and a distance adjusting member 2b for adjusting an axial distance between the shafts 2a. Is rotated with respect to each shaft 2a, so that each shaft 2a approaches or separates in the axial direction. The shaft 2 a is a ball screw having a threaded portion on the outer peripheral surface, and one end of the shaft 2 a is screwed into the embedded nut 1 a of the concrete plate 1. In this case, each shaft 2a is fixed to the concrete plate 1 by tightening a first fixing nut 2c screwed to each shaft 2a in contact with the embedded nut 1a. The interval adjusting member 2b is formed of a cylindrical member having a threaded portion on the inner peripheral surface, and both end sides thereof are screwed to the other end side of each shaft 2a. In this case, as shown in FIG. 4, the screw portion 2 b-1 on the one end side in the axial direction and the screw portion 2 b-2 on the other end side in the axial direction of the interval adjusting member 2 b are opposite to each other. When the member 2b is rotated, the shafts 2a are moved in directions opposite to each other in the axial direction.

第１の連結部材３は正方形の板状に形成され、４つのセパレータ２のシャフト２ａをそれぞれ挿通する４つの孔３ａを有している。   The first connecting member 3 is formed in a square plate shape and has four holes 3a through which the shafts 2a of the four separators 2 are inserted.

第２の連結部材４は長方形の板状に形成され、２つのセパレータ２のシャフト２ａをそれぞれ挿通する２つの孔４ａを有している。   The second connecting member 4 is formed in a rectangular plate shape and has two holes 4a through which the shafts 2a of the two separators 2 are inserted.

以上の構成からなるコンクリート型枠を用いて建物の壁を施工する場合は、まずセパレータ２のシャフト２ａをコンクリート板１の埋込ナット１ａに螺合し、第１の固定ナット２ｃを埋込ナット１ａに当接させて締め込むことによりシャフト２ａをコンクリート板１に固定する。次に、互いに上下左右の配列方向に隣り合うコンクリート板１のセパレータ２同士を第１の連結部材３または第２の連結部材４によって連結する。この場合、４つのコンクリート板１同士が隣り合う箇所では、４つのセパレータ２のシャフト２ａを第１の連結部材３の各孔３ａにそれぞれ挿入し、２つのコンクリート板１同士が隣り合う箇所では、２つのセパレータ２のシャフト２ａを第２の連結部材４の各孔４ａにそれぞれ挿入する。また、第１の連結部材３または第２の連結部材４の厚さ方向両側には、シャフト２ａに螺合する第２の固定ナット２ｄがそれぞれ配置され、各第２の固定ナット２ｄを第１の連結部材３または第２の連結部材４を挟み込むように締め付けることにより、第１の連結部材３または第２の連結部材４がシャフト２ａに固定される。その際、第１の連結部材３または第２の連結部材４は、各第２の固定ナット２ｄの締め付け位置によってシャフト２ａの軸方向任意の位置に固定される。   When constructing a building wall using the concrete form having the above-described configuration, first, the shaft 2a of the separator 2 is screwed into the embedded nut 1a of the concrete plate 1, and the first fixing nut 2c is connected to the embedded nut. The shaft 2a is fixed to the concrete plate 1 by being brought into contact with 1a and tightening. Next, the separators 2 of the concrete plates 1 adjacent to each other in the vertical and horizontal arrangement directions are connected by the first connecting member 3 or the second connecting member 4. In this case, at the place where the four concrete plates 1 are adjacent to each other, the shaft 2a of the four separators 2 is inserted into each hole 3a of the first connecting member 3, and at the place where the two concrete plates 1 are adjacent to each other, The shafts 2a of the two separators 2 are inserted into the holes 4a of the second connecting member 4, respectively. Further, on both sides in the thickness direction of the first connecting member 3 or the second connecting member 4, second fixing nuts 2d screwed to the shaft 2a are respectively disposed, and each second fixing nut 2d is connected to the first fixing nut 2d. The first connecting member 3 or the second connecting member 4 is fixed to the shaft 2a by tightening the connecting member 3 or the second connecting member 4 so as to be sandwiched therebetween. In that case, the 1st connection member 3 or the 2nd connection member 4 is fixed to the axial direction arbitrary position of the shaft 2a by the fastening position of each 2nd fixing nut 2d.

前述のようにして、上下左右に配列されたコンクリート板１を各連結板３，４によって連結し、互いに厚さ方向に対向するコンクリート板１のシャフト２ａに間隔調整部材２ｂを螺合することにより、各シャフト２ａを互いに間隔調整部材２ｂを介して連結する。これにより、上下左右に配列されたコンクリート板１同士が互いに固定されるとともに、互いに厚さ方向に対向するコンクリート板１同士がセパレータ２によって対向方向に間隔をおいて保持され、各コンクリート板１による型枠部５が形成される。この場合、間隔調整部材２ｂを回動してセパレータ２の軸方向全体の長さを変えることにより、互いに対向するコンクリート板１の間隔が所定の間隔になるように調整される。   As described above, the concrete plates 1 arranged in the vertical and horizontal directions are connected by the connecting plates 3 and 4, and the interval adjusting member 2b is screwed onto the shaft 2a of the concrete plate 1 facing each other in the thickness direction. The shafts 2a are connected to each other via a distance adjusting member 2b. As a result, the concrete plates 1 arranged in the vertical and horizontal directions are fixed to each other, and the concrete plates 1 facing each other in the thickness direction are held by the separator 2 at intervals in the facing direction. A mold part 5 is formed. In this case, the interval adjusting member 2b is rotated to change the overall length of the separator 2 in the axial direction so that the interval between the concrete plates 1 facing each other is adjusted to a predetermined interval.

以上のようにして形成された型枠部５の内部に図示しない鉄筋を配置してコンクリートを打設し、コンクリート硬化後もコンクリート板１を残置することにより、コンクリート板１が一体となったコンクリート構造物（壁）が形成される。この場合、各連結板３，４は型枠部５の内部に配置されているので、各連結板３，４が外部に露出することがない。   A concrete in which the concrete plate 1 is integrated by placing a reinforcing bar (not shown) inside the mold part 5 formed as described above, placing concrete, and leaving the concrete plate 1 after the concrete is hardened. A structure (wall) is formed. In this case, since each connecting plate 3 and 4 is arranged inside the mold part 5, each connecting plate 3 and 4 is not exposed to the outside.

このように、本実施形態によれば、複数のコンクリート板１を互いに端面同士が当接するように上下左右に配列するとともに、互いに厚さ方向に対向するコンクリート板１同士をセパレータ２によって対向方向に間隔をおいて保持し、互いに隣り合うコンクリート板１のセパレータ２同士を第１の連結部材３または第２の連結部材４によって型枠部５の内部で連結することにより、各コンクリート板１による型枠部５を形成し、型枠部５内にコンクリートを打設することによりコンクリート構造物を形成し、各コンクリート板１を残置してコンクリート構造物と一体化するようにしたので、従来のようなコンクリート硬化後における型枠材の撤去が不要であるとともに、型枠材を支持するための複雑な部材の解体及び撤去も必要とすることがなく、現場作業の省力化を十分に図ることができる。   Thus, according to the present embodiment, a plurality of concrete plates 1 are arranged vertically and horizontally so that their end faces are in contact with each other, and the concrete plates 1 facing each other in the thickness direction are separated by the separator 2 in the facing direction. By holding the separators 2 of the concrete plates 1 adjacent to each other and connecting the separators 2 of the concrete plates 1 adjacent to each other inside the mold frame portion 5 by the first connecting member 3 or the second connecting member 4, the molds by the concrete plates 1 are used. Since the frame part 5 is formed and the concrete structure is formed by placing concrete in the mold part 5, and each concrete plate 1 is left and integrated with the concrete structure, It is not necessary to remove the formwork after the concrete is hardened, and it is also necessary to dismantle and remove the complicated members to support the formwork Ku, it is possible to achieve a sufficient labor saving of field operations.

この場合、互いに隣り合うコンクリート板１のセパレータ２同士を各連結部材３，４によって連結することにより、上下左右に配列されるコンクリート板１同士を固定するようにしているので、コンクリート板１同士を直接固定する必要がない。即ち、コンクリート板１同士を直接固定する場合は、例えば固定用の部材を結合するための加工をコンクリート板１に施す必要があるが、本実施形態ではそのような加工を必要としないので、コンクリート板１の構造を簡素化することができる。   In this case, by connecting the separators 2 of the concrete plates 1 adjacent to each other by the connecting members 3 and 4, the concrete plates 1 arranged in the vertical and horizontal directions are fixed. There is no need to fix directly. That is, when directly fixing the concrete plates 1 to each other, for example, it is necessary to perform processing for joining the fixing members on the concrete plate 1, but in this embodiment, such processing is not required. The structure of the plate 1 can be simplified.

更に、セパレータ２同士が各連結部材３，４によって型枠部５の内部で連結されるので、各連結部材３，４が型枠部５の外部に露出することがなく、各連結部材３，４の露出によってコンクリート構造物の外観が損なわれることがないという利点もある。   Furthermore, since the separators 2 are connected to each other inside the mold part 5 by the connecting members 3 and 4, the connecting members 3 and 4 are not exposed to the outside of the mold part 5, and the connecting members 3 and 4 are not exposed. There is also an advantage that the appearance of the concrete structure is not impaired by the exposure of 4.

また、セパレータ２を四角形状のコンクリート板１の四隅に設け、配列方向に隣り合うコンクリート板１における最も近接するセパレータ２同士を第１の連結部材３または第２の連結部材４によって連結するようにしたので、各連結板３，４を小型化することができ、構造の簡素化を図ることができる。   Further, the separators 2 are provided at the four corners of the rectangular concrete plate 1 so that the closest separators 2 in the concrete plates 1 adjacent to each other in the arrangement direction are connected by the first connecting member 3 or the second connecting member 4. Therefore, each connecting plate 3 and 4 can be reduced in size, and the structure can be simplified.

この場合、各連結部材３，４にセパレータ２のシャフト２ａを挿通する複数の孔３ａ，４ａを設け、各孔３ａまたは各孔４ａにセパレータ２のシャフト２ａを挿通することによりセパレータ２同士を連結するようにしたので、セパレータ２同士を容易に連結することができ、各連結部材３，４によるセパレータ２の連結作業を効率よく行うことができる。   In this case, each of the connecting members 3 and 4 is provided with a plurality of holes 3a and 4a through which the shaft 2a of the separator 2 is inserted, and the separators 2 are connected to each other by inserting the shaft 2a of the separator 2 into each hole 3a or each hole 4a. Since it was made to do, separators 2 can be connected easily and the connection operation | work of the separator 2 by each connection member 3 and 4 can be performed efficiently.

また、各連結部材３，４をシャフト２ａの軸方向任意の位置で固定可能に構成したので、連結部材３，４をシャフト２ａの軸方向にずらすことにより、隣り合うコンクリート板１同士の厚さ方向の位置合わせを行うことができ、各コンクリート板１をコンクリート構造物の表面において段差を生じないように配列することができる。   Moreover, since each connection member 3 and 4 was comprised so that fixation in the axial direction arbitrary position of the shaft 2a was possible, by shifting the connection members 3 and 4 to the axial direction of the shaft 2a, the thickness of adjacent concrete boards 1 is mutually. Directional alignment can be performed, and the concrete plates 1 can be arranged so as not to cause a step on the surface of the concrete structure.

更に、セパレータ２は、互いに厚さ方向に対向して配置されるコンクリート板１に一端をそれぞれ固定された一対のシャフト２ａと、両端側が各シャフト２ａの他端側にそれぞれ螺合する間隔調整部材２ｂとからなり、間隔調整部材２ｂを各シャフト２ａの軸回りに回動することにより、各シャフト２ａが軸方向に接近または離間するように構成したので、間隔調整部材２ｂの回動によって容易にコンクリート板１の対向方向の間隔を変えることができ、間隔調整部材２ｂによる調整作業を効率よく行うことができる。   Further, the separator 2 includes a pair of shafts 2a each having one end fixed to a concrete plate 1 disposed opposite to each other in the thickness direction, and an interval adjusting member having both ends screwed to the other ends of the shafts 2a. 2b, and by rotating the interval adjusting member 2b around the axis of each shaft 2a, each shaft 2a is configured to approach or separate in the axial direction. The interval in the opposing direction of the concrete plate 1 can be changed, and the adjustment work by the interval adjusting member 2b can be performed efficiently.

The anchor member 6 is made of a metal mesh, a reinforcing bar, a metal fiber, or the like, part of which is embedded in the concrete plate 1, and the other part is one surface of the concrete plate 1 (the inner surface of the mold part 5). Exposed to the side. The anchor member 6 has substantially the same vertical dimension as one surface of the concrete plate 1, and in the process of manufacturing the concrete plate 1, about half of the thickness direction is arranged in the concrete plate 1 before hardening, It is integrated with the concrete plate 1 after curing.

Integrated with cast concrete.

このように、本実施形態によれば、コンクリート板１に一部が埋設されたアンカー部材６を備え、アンカー部材６の他の部分を型枠部５内の打設コンクリート内に配置し、硬化後の打設コンクリートとアンカー部材６とを一体化するようにしたので、各コンクリート板１と型枠部５内の打設コンクリートとを強固に結合することができ、コンクリート構造物全体の強度を高めることができる。   As described above, according to this embodiment, the anchor member 6 partially embedded in the concrete plate 1 is provided, and the other part of the anchor member 6 is disposed in the cast concrete in the mold part 5 and hardened.
