Description

本発明は、耐力壁パネルに関する。   The present invention relates to a load-bearing wall panel.

耐力壁パネルとして筋交い式のブレースを用いたものは、従来より提供されているが、筋交い式のブレースでは、パネル一つ当たりの耐力アップに限界があり、建物の耐震性能を高めるうえで、プランニングに難しさを生じさせやすい。   The use of bracing braces as load-bearing wall panels has been provided in the past, but bracing braces have a limit in increasing the proof strength per panel, and plan to increase the seismic performance of the building. It is easy to cause difficulty.

本発明は、上記のような問題点に鑑み、水平力に対して高い耐力性能を発揮することができ、しかも、それをコスト的に有利に実現することができる、耐力壁パネルを提供することを課題とする。   In view of the above-described problems, the present invention provides a load-bearing wall panel that can exhibit high yield strength performance against horizontal force and that can be realized advantageously in terms of cost. Is an issue.

上記の課題は、上下方向に延びるリブと平板部とが左右方向に交互に繰り返す波形鋼板を膜式耐力要素として備えていることを特徴とする耐力壁パネルによって解決される。   The above-described problem is solved by a load-bearing wall panel including a corrugated steel sheet as a film-type load-bearing element in which ribs extending in the vertical direction and flat plate portions are alternately repeated in the left-right direction.

この耐力壁パネルでは、リブ間の各平板部が左右のリブに面外変形を拘束された単位膜部となり、これら各単位膜部の面剛性によって水平力に抵抗し、高い耐力性能を発揮することができる。   In this load-bearing wall panel, each flat plate portion between the ribs becomes a unit film portion in which out-of-plane deformation is constrained by the left and right ribs, resists horizontal force by the surface rigidity of each unit film portion, and exhibits high strength performance. be able to.

しかも、平板部とリブを波形鋼板によって形成しているので、上記のような高い耐力性能を発揮することができる耐力壁パネルをコスト的に有利に製作することができる。   And since the flat plate part and the rib are formed with the corrugated steel plate, the load-bearing wall panel capable of exhibiting the high load-bearing performance as described above can be manufactured advantageously in terms of cost.

上記の耐力壁パネルにおいて、波形鋼板のリブ突出側の面部に、コンクリート部が各リブを埋込み状態とするように備えられている場合は、各リブがコンクリート部によって補剛され、水平力に対する各平板部の面剛性による抵抗力を高くすることができて、耐力性能を高めることができる。   In the above-mentioned load-bearing wall panel, when the concrete portion is provided so that each rib is embedded in the surface portion on the rib protruding side of the corrugated steel plate, each rib is stiffened by the concrete portion, The resistance force due to the surface rigidity of the flat plate portion can be increased, and the proof stress performance can be enhanced.

特に、波形鋼板の各リブがその基端側を細くしてコンクリート中に埋込み状態にされている場合は、コンクリート部による各リブの補剛をしっかりとしたものにすることができ、また、コンクリート部と波形鋼板とを、リブとコンクリートとの係合作用で容易に結合することができる。   In particular, when each rib of the corrugated steel sheet is made to be embedded in concrete with its base end side narrowed, the stiffening of each rib by the concrete part can be made firm, The part and the corrugated steel sheet can be easily coupled by the engaging action of the rib and the concrete.

また、上記の耐力壁パネルにおいて、波形鋼板のリブ突出側とは反対側の面部に、透湿性を有する断熱材が備えられ、リブ内の空隙が上下方向に延びる放湿用の通気部になっている場合は、上記の膜式耐力要素との組み合わせにおいて、簡素な構造により結露の発生を防ぐことができる。   Further, in the above load-bearing wall panel, a heat-insulating material having moisture permeability is provided on the surface portion of the corrugated steel plate opposite to the rib protruding side, and the air gap in the rib serves as a moisture releasing ventilation portion extending in the vertical direction. In such a case, in a combination with the above-described film-type load bearing element, it is possible to prevent the occurrence of condensation with a simple structure.

本発明は、以上のとおりのものであるから、水平力に対して高い耐力性能を発揮することができ、しかも、それをコスト的に有利に実現することができる。   Since the present invention is as described above, it is possible to exhibit a high yield strength performance with respect to a horizontal force, and it can be realized advantageously in terms of cost.

In addition, the gaps 7 extending in the vertical direction in the ribs 5 function as a ventilation portion for releasing moisture from the heat insulating material 4 side.

そして、上記の波形鋼板3において、リブ5…の突出する側の面部、即ち屋外側の面部には、コンクリート部8が、各リブ5…を埋込み状態にするようにして備えられると共に、波形鋼板3の各リブ5…はその基端側が細くされていて、波形鋼板3とコンクリート部8とがしっかりと結合されるようになされており、波形鋼板3とコンクリート部とによる合成版9が形成されて耐力壁パネル1がコンクリート系の外壁パネルに形成されている。   In the corrugated steel sheet 3, a concrete portion 8 is provided on the surface portion on the projecting side of the ribs 5, that is, the outdoor surface portion, so that the ribs 5 are embedded, and the corrugated steel plate. 3 is thinned at the base end side so that the corrugated steel plate 3 and the concrete portion 8 are firmly joined, and a composite plate 9 is formed by the corrugated steel plate 3 and the concrete portion. Thus, the load-bearing wall panel 1 is formed on a concrete outer wall panel.

なお、コンクリート部8の屋外側の面部は、そのまま屋外に露出させて外壁面を構成するようにしてもよいし、コンクリート部8の屋外側の面部をタイル貼りなどにするようにしてもよい。   The outdoor side surface portion of the concrete portion 8 may be exposed to the outside as it is to form an outer wall surface, or the outdoor side surface portion of the concrete portion 8 may be tiled.

上記の耐力壁パネル1では、リブ5…間の各平板部6…が左右のリブ5,5に面外変形を拘束された単位膜部となり、これら各単位膜部6…がそれぞれの面剛性によって水平力に強く抵抗し、高い耐力性能を発揮することができる。   In the above-mentioned load-bearing wall panel 1, the flat plate portions 6 between the ribs 5 are unit film portions in which the left and right ribs 5 and 5 are restrained from out-of-plane deformation, and the unit film portions 6 have their surface rigidity. It can resist the horizontal force strongly and can exhibit high strength performance.

特に、本実施形態では、波形鋼板3においてリブ5…の突出する側の面部には、各リブ5がコンクリート部8内に埋込み状態となるように備えられているので、各リブ5…がコンクリート部8によって補剛され、水平力に対する各平板部6…の面剛性による抵抗力を高くすることができて、耐力性能を高めることができる。   In particular, in the present embodiment, the ribs 5 are provided in the corrugated steel plate 3 so that the ribs 5 are embedded in the concrete portion 8 on the surface of the corrugated steel plate 3 from which the ribs 5 protrude. It is stiffened by the portion 8 and the resistance force by the surface rigidity of each flat plate portion 6...

とりわけ本実施形態では、波形鋼板3の各リブ5…がその基端側を細くしてコンクリート部8との結合状態がしっかりと保持されるようになされているので、コンクリート部8による各リブ5…の補剛をしっかりとしたものにすることができる。   In particular, in the present embodiment, the ribs 5 of the corrugated steel plate 3 are thinned at the base end side so that the connection state with the concrete portion 8 is firmly held. The stiffening of… can be made solid.

そして、上記のような高い耐力性能を発揮するもとになる平板部6…とリブ5…を波形鋼板によって形成しているので、そのような耐力壁パネル1をコスト的に有利に製作することができる。   And since the flat plate part 6 ... and the rib 5 ... used as the bases which demonstrate the above high yield strength performances are formed with the corrugated steel plate, manufacturing such a load bearing wall panel 1 advantageously in cost. Can do.

また、上記の耐力壁パネル1では、膜式耐力要素を鋼製する波形鋼板3の各リブ5…内の空隙7…を、透湿性断熱材4の側からの湿気を放湿するための通気部として機能させるようにしているので、簡素な構造により結露の発生を防ぐことができる。   Further, in the above-mentioned load-bearing wall panel 1, ventilation for releasing moisture from the moisture-permeable heat insulating material 4 through the gaps 7 in the ribs 5 of the corrugated steel plate 3 made of steel as the membrane-type load bearing element. Since it is made to function as a part, generation | occurrence | production of dew condensation can be prevented with a simple structure.

もちろん、波形鋼板3もコンクリート部8を補強する作用を行い、コンクリート部8のクラックの発生を防ぐことができると共に、コンクリート部8におけるコンクリート使用量を少なくしてコンクリート部8の重量を小さく抑えることも可能となる。   Of course, the corrugated steel plate 3 also acts to reinforce the concrete portion 8 and can prevent the occurrence of cracks in the concrete portion 8, and reduce the amount of concrete used in the concrete portion 8 to keep the weight of the concrete portion 8 small. Is also possible.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、上記の実施形態では、耐力壁パネルをコンクリート系の外壁パネルに構成した場合を示したが、コンクリート系以外の外壁パネルに構成されていてもよいし、コンクリート部の存在の有無に拘わらず外壁パネル以外の耐力壁パネルとして構成されていてもよい。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where the load-bearing wall panel is configured as a concrete-based outer wall panel has been described. However, the load-bearing wall panel may be configured as a non-concrete-type outer wall panel, and regardless of the presence or absence of a concrete portion. You may be comprised as load-bearing wall panels other than an outer wall panel.
