Description

本発明は、スリット材をコンクリートに打ち込んで耐震スリットを形成する耐震スリットの施工方法およびこのスリット材の支持構造に関する。   The present invention relates to an earthquake-resistant slit construction method for forming an earthquake-resistant slit by driving a slit material into concrete and a support structure for the slit material.

従来より、柱や梁などの鉄筋コンクリート造の構造体に、鉄筋コンクリート造の非耐力壁を連続して設ける場合がある。この場合、地震時に、構造体の挙動が非耐力壁に拘束されて構造体が大きく損壊するおそれがあるため、構造体と非耐力壁との接合部分にスリット材を打ち込んで、耐震スリットを設けることが多い。   Conventionally, non-bearing walls made of reinforced concrete are sometimes provided continuously on reinforced concrete structures such as columns and beams. In this case, since the behavior of the structure is constrained by the non-bearing wall during an earthquake, the structure may be greatly damaged. Therefore, a slit material is provided at the joint between the structure and the non-bearing wall to provide a seismic slit. There are many cases.

この耐震スリットは、例えば、以下の手順で構築される。まず、非耐力壁と構造体との接合部分にスリット材を固定して、このスリット材を挟み込むように型枠を建て込む。次に、この型枠内にコンクリートを打設する。その後、スリット材を脱型したり、あるいは、スリット材をそのままコンクリート躯体に打ち込んだりすることで、耐震スリットとする。   This seismic slit is constructed in the following procedure, for example. First, a slit material is fixed to a joint portion between the non-bearing wall and the structure, and a mold is built so as to sandwich the slit material. Next, concrete is placed in the formwork. After that, the slit material is removed from the mold, or the slit material is directly driven into the concrete frame to form an earthquake resistant slit.

ここで、スリット材を鉄筋材に固定する方法としては、スリット材をなまし線（番線）で直接鉄筋材に縛り付けて固定する方法（特許文献１参照）や、スリット材に棒状のつなぎ材を設けておき、このつなぎ材をなまし線で鉄筋材に縛り付けて固定する方法（特許文献２参照）がある。   Here, as a method of fixing the slit material to the reinforcing bar material, a method of fixing the slit material by directly tying the slit material to the reinforcing bar material with an annealing wire (numbered wire) (see Patent Document 1), or a rod-like connecting material to the slit material. There is a method (see Patent Document 2) in which the connecting material is fixed by tying the connecting material to the reinforcing bar with an annealing wire.

特許第３３１２７２４号公報Japanese Patent No. 3312724 特開２００６−３７３４５号公報JP 2006-37345 A

しかしながら、特許文献１、２の方法では、スリット材をなまし線で鉄筋材に固定しているため、コンクリート打設時にスリット材が生コンクリートに押されてなまし線が切れてしまい、スリット材の位置がずれるおそれがあった。その結果、スリット材の取付け箇所ではコンクリートのかぶり厚を確保できない、という問題があった。
また、鉄筋材は精度よく配筋されない場合があるため、スリット材を鉄筋材に固定した場合には、スリット材を高い精度で配置できないおそれがあった。 However, in the methods of Patent Documents 1 and 2, since the slit material is fixed to the reinforcing bar material with an annealed wire, the slit material is pushed by the ready-mixed concrete at the time of placing the concrete, and the annealed wire is cut. There was a risk that the position of would shift. As a result, there was a problem that the cover thickness of the concrete could not be secured at the installation location of the slit material.
Further, since the reinforcing bar material may not be accurately arranged, when the slit material is fixed to the reinforcing bar material, the slit material may not be arranged with high accuracy.

本発明は、スリット材を高精度で配置して、かつ、位置ずれを防止できる耐震スリット施工方法およびスリット材支持構造を提供することを目的とする。   It is an object of the present invention to provide a seismic slit construction method and a slit material support structure in which a slit material can be arranged with high accuracy and displacement can be prevented.

耐震スリット１０は、腰壁１２の壁厚方向に延びて、壁厚方向の一端側から他端側に向かうに従って幅が広くなっている。 The earthquake-resistant slit 10 is provided at a joint portion between a column 11 as a reinforced concrete structure and a waist wall 12 as a non-bearing wall of reinforced concrete provided continuously to the column 11.
The earthquake-resistant slit 10 extends in the wall thickness direction of the waist wall 12, and becomes wider as it goes from one end side to the other end side in the wall thickness direction.

この耐震スリット１０の施工方法１について、図２のフローチャートに沿って、図３および図４を参照しながら説明する。
まず、ステップＳ１では、柱１１の柱筋１４を配筋して、この柱１１の一部の型枠を建て込むとともに、腰壁１２の両側面を覆う型枠のうちの片方の型枠２０Ａを建て込む。この型枠２０Ａには、連結部材としてのセパレータ２１、単管２２、およびフォームタイ（登録商標）２３を取り付けておく。 The construction method 1 of the seismic slit 10 will be described with reference to FIGS. 3 and 4 along the flowchart of FIG.
First, in step S1, the column reinforcement 14 of the column 11 is arranged, a part of the form of the column 11 is built, and one of the forms covering the both side surfaces of the waist wall 12 is 20A. Build in. A separator 21, a single tube 22, and a foam tie (registered trademark) 23 as connecting members are attached to the mold 20 </ b> A.

ステップＳ２では、腰壁１２の壁筋１３を配筋する。具体的には、縦筋１３１および横筋１３２をダブル配筋する。
ステップＳ３では、壁厚方向に延びて一端側から他端側に向かうに従って幅が広くなるように、スリット材３０を型枠２０Ａに取り付ける。このとき、壁筋１３の横筋１３２は、このスリット材３０に対してかぶり厚を確保できるように切断しておく。 In step S2, the wall bars 13 of the waist wall 12 are arranged. Specifically, the vertical bars 131 and the horizontal bars 132 are double arranged.
In step S3, the slit member 30 is attached to the mold 20A so as to extend in the wall thickness direction and increase in width from one end side to the other end side. At this time, the horizontal bars 132 of the wall bars 13 are cut so as to ensure a cover thickness with respect to the slit material 30.

スリット材３０は、木材または合成樹脂で形成されており、このスリット材３０の表面には、剥離剤が塗布されている、または、メラミン化粧板が貼り付けられている。また、スリット材３０は、平面視で、長さが腰壁１２の壁厚に等しく、かつ、壁厚方向の一端側から他端側に向かうに従って幅が広くなっている。さらに、このスリット材３０には、上下方向の所定間隔おきに、水平に延びる貫通孔３１が形成されている。   The slit material 30 is made of wood or synthetic resin, and a release agent is applied to the surface of the slit material 30 or a melamine decorative board is attached. In addition, the slit member 30 has a length equal to the wall thickness of the waist wall 12 in a plan view, and the width becomes wider from one end side to the other end side in the wall thickness direction. Further, the slit material 30 is formed with horizontally extending through holes 31 at predetermined intervals in the vertical direction.

具体的には、型枠２０Ａのセパレータ２１を、スリット材３０の貫通孔３１に挿通することで、スリット材３０を型枠２０Ａに取り付ける。   Specifically, the slit material 30 is attached to the mold 20A by inserting the separator 21 of the mold 20A through the through hole 31 of the slit material 30.

ステップＳ４では、柱１１の残る型枠を建て込むとともに、腰壁１２の残る型枠２０Ｂを建て込んで、一対の型枠２０Ａ、２０Ｂの間にスリット材３０を挟み込む。
さらに、型枠２０Ｂから突出したセパレータ２１にフォームタイ２３を取り付けて、このフォームタイ２３で単管２２を締め付ける。これにより、腰壁１２の両側面を覆う一対の型枠２０Ａ、２０Ｂは、セパレータ２１で互いに連結されるとともに、スリット材３０は、これら一対の型枠２０Ａ、２０Ｂの間に配置される。 In step S4, the formwork with the pillar 11 remaining is erected, and the mold form 20B with the waist wall 12 is erected, and the slit material 30 is sandwiched between the pair of molds 20A, 20B.

Thus, the pair of molds 20A and 20B covering both side surfaces of the waist wall 12 are connected to each other by the separator 21, and the slit material 30 is disposed between the pair of molds 20A and 20B.

ステップＳ５では、一対の型枠２０Ａ、２０Ｂの内部にコンクリートを打設する。
ステップＳ６では、一対の型枠２０Ａ、２０Ｂを解体するとともに、スリット材３０をこのスリット材３０の広くなっている側に引き抜くことで、スリット材３０を取り外す。その後、このスリット材３０を取り外した部分に別の部材を取り付けるか、あるいは、スリット材３０を取り外したそのままの状態とすることで、耐震スリット１０を形成する。 In step S5, concrete is placed inside the pair of molds 20A and 20B.
In step S <b> 6, the pair of molds 20 </ b> A and 20 </ b> B are disassembled, and the slit material 30 is removed by pulling the slit material 30 to the wide side of the slit material 30. Then, another member is attached to the part from which the slit material 30 is removed, or the seismic slit 10 is formed by leaving the slit material 30 as it is.

本実施形態によれば、以下のような効果がある。
（１）スリット材３０を壁厚方向に貫通し、腰壁１２の両側面を覆う一対の型枠２０Ａ、２０Ｂ同士を連結するように、セパレータ２１を配置した。よって、コンクリート打設時にスリット材３０が生コンクリートに押されても、セパレータ２１を介してスリット材を型枠２０Ａ、２０Ｂで支持するので、スリット材３０の位置がずれるのを防止できる。したがって、スリット材３０の取付け箇所でコンクリートのかぶり厚を確保できる。
また、スリット材３０を一対の型枠２０Ａ、２０Ｂに取り付けるので、スリット材３０を高精度で配置できる。

(1) The separator 21 was disposed so as to connect the pair of molds 20A and 20B that penetrate the slit member 30 in the wall thickness direction and cover both side surfaces of the waist wall 12. Therefore, even if the slit material 30 is pushed by the ready-mixed concrete when placing concrete, the slit material 30 is supported by the molds 20A and 20B via the separator 21, so that the position of the slit material 30 can be prevented from shifting. Therefore, the concrete cover thickness can be secured at the location where the slit member 30 is attached.
Moreover, since the slit material 30 is attached to the pair of molds 20A and 20B, the slit material 30 can be arranged with high accuracy.
Further, when the molds 20A and 20B are disassembled, the slit material 30 can be easily removed by pulling the slit material 30 to the wide side of the slit material, so that the slit material 30 can be used repeatedly.

（２）スリット材３０を木材または合成樹脂で形成したので、スリット材３０を軽量化でき、取り扱いが容易となる。
また、スリット材３０の表面に剥離剤を塗布した、または、メラミン化粧板を貼り付けた。よって、スリット材３０がコンクリート躯体から剥離し易くなり、コンクリート打設後にスリット材３０をコンクリート躯体から容易に取り外すことができる。 (2) Since the slit member 30 is made of wood or synthetic resin, the slit member 30 can be reduced in weight and easy to handle.
Moreover, the release agent was apply | coated to the surface of the slit material 30, or the melamine decorative board was affixed. Therefore, it becomes easy to peel the slit material 30 from the concrete frame, and the slit material 30 can be easily removed from the concrete frame after placing the concrete.

なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、本実施形態では、スリット材３０を腰壁１２の壁厚方向の一端側から他端側に向かうに従って幅が広くなるように形成したが、これに限らず、スリット材を腰壁１２の壁厚方向に一様の幅となるように形成してもよい。
また、本実施形態では、セパレータ２１の両端にＰコンを取り付けていないが、セパレータの両端にＰコンを取り付けてもよい。 It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the present embodiment, the slit member 30 is formed so that the width becomes wider from one end side to the other end side in the wall thickness direction of the waist wall 12. You may form so that it may become a uniform width | variety in a wall thickness direction.
