下床と上床との間に確保すべき床下空間の高さ寸法等は、施工条件や需要者のニーズによって異なるのが通常であるので、寸法・形状の異なる複数種類の支持脚を準備しておきたいところである。ところが、鋳造品からなる支持脚の寸法・形状を変更するためには、鋳造型を作りかえる必要があるので、コストが嵩んでしまう。 Since the height of the underfloor space to be secured between the lower floor and the upper floor usually varies depending on the construction conditions and the needs of customers, prepare multiple types of support legs with different dimensions and shapes. I want to make it. However, in order to change the size and shape of the support legs made of a cast product, it is necessary to change the casting mold, which increases the cost.

そこで、本発明は、施工条件や需要者のニーズに低コストで対応することが可能な二重床構造を提供することを課題とする。 Then, this invention makes it a subject to provide the double floor structure which can respond to construction conditions and a customer's needs at low cost.

本発明に係る二重床構造は、下床に設置される複数の支持脚と、隣り合う前記支持脚同士を連結する連結部材と、上床を構成するための上床構造体とを具備する二重床構造であって、前記支持脚は、前記上床構造体を支持する上部材と、前記上部材を下側から支持する柱部材とを備えており、前記柱部材は、アルミニウム合金製の押出形材からなり、かつ、その押出方向が上下方向となるように配置されており、前記連結部材は、アルミニウム合金製の押出形材からなり、かつ、その押出方向が前記柱部材の押出方向に直交する方向となるように配置されていることを特徴とする。 The double floor structure according to the present invention is a double floor structure comprising a plurality of support legs installed on the lower floor, a connecting member for connecting the adjacent support legs, and an upper floor structure for constituting the upper floor. In the floor structure, the support leg includes an upper member that supports the upper floor structure, and a column member that supports the upper member from below, and the column member is an extruded form made of aluminum alloy. The connecting member is made of an aluminum alloy extruded shape, and the direction of extrusion is perpendicular to the direction of extrusion of the column member. It is arrange | positioned so that it may become a direction to do.

要するに本発明は、支持脚の構成部品である柱部材と、隣り合う支持脚同士を連結する連結部材とを、アルミニウム合金製の押出形材を利用して形成したところに特徴がある。 In short, the present invention is characterized in that a pillar member, which is a component part of a support leg, and a connecting member that connects adjacent support legs are formed using an extruded shape made of an aluminum alloy.

本発明によれば、二重床構造の寸法形状を容易に変更することが可能になるので、施工条件や需要者のニーズに低コストで対応することが可能となる。すなわち、本発明によれば、柱部材の素となる押出形材の切断長さを変更するだけで、支持脚の高さ寸法を変更することができるので、床下空間の高さ寸法を容易に変更することが可能となる。また、本発明によれば、連結部材の素となる押出形材の切断長さを変更するだけで、隣り合う支持脚の離間距離を容易に変更することができる。 According to the present invention, the dimensional shape of the double floor structure can be easily changed, so that it is possible to respond to the construction conditions and the needs of consumers at low cost. That is, according to the present invention, it is possible to change the height dimension of the support leg simply by changing the cutting length of the extruded profile that is the element of the column member. It becomes possible to change. In addition, according to the present invention, it is possible to easily change the separation distance between adjacent support legs simply by changing the cutting length of the extruded profile that is the element of the connecting member.

しかも、本発明によれば、隣り合う支持脚同士が連結部材で連結されているので、各支持脚を単独で立設した場合に比べて、各支持脚に発生する曲げ変形やせん断変形が抑制されるようになり、したがって、支持脚の高さ寸法を大きくした場合であっても、横揺れが発生し難くなる。なお、一の連結部材により隣り合う支持脚同士を連結して門形やＨ形を呈する構造体を形成してもよいし、複数の連結部材により隣り合う支持脚同士を連結して井桁状や梯子状を呈する構造体を形成してもよい。 Moreover, according to the present invention, the adjacent support legs are connected by the connecting member, so that bending deformation and shear deformation generated in each support leg are suppressed as compared with the case where each support leg is erected independently. Therefore, even when the height dimension of the support leg is increased, the roll does not easily occur. The adjacent support legs may be connected to each other by one connecting member to form a gate-like or H-shaped structure, or the adjacent supporting legs may be connected to each other by a plurality of connecting members. A structure having a ladder shape may be formed.

本発明においては、前記柱部材の側面に前記連結部材を接続することが望ましい。この場合には、前記柱部材の側面にボルト収容溝を形成しておくとともに、前記連結部材の端部にボルト挿通部を形成しておき、前記ボルト挿通部の一端側から前記ボルト挿通部に挿通されたボルトの軸部を前記ボルト挿通部の他端側に配置されたナットに螺合するとともに、前記ボルトの頭部または前記ナットを前記ボルト収容溝に抱持させることが望ましい。なお、ボルト収容溝は上下方向に沿って形成し、ボルト挿通部は水平方向に沿って形成する。このようにすると、柱部材と連結部材とを簡単に接合することが可能になるので、二重床構造を簡易迅速に組み立てることが可能となる。また、連結部材の接続位置を、ボルト収容溝に沿って上下に移動させることができるので、二重床構造の寸法・形状を容易に変更することが可能になる。 In the present invention, it is desirable to connect the connecting member to a side surface of the pillar member. In this case, a bolt housing groove is formed on the side surface of the pillar member, a bolt insertion portion is formed at an end portion of the connecting member, and the bolt insertion portion is formed from one end side of the bolt insertion portion. It is desirable that the shaft portion of the inserted bolt is screwed into a nut disposed on the other end side of the bolt insertion portion, and the head portion of the bolt or the nut is held in the bolt receiving groove. The bolt housing groove is formed along the vertical direction, and the bolt insertion portion is formed along the horizontal direction. If it does in this way, since it becomes possible to join a pillar member and a connection member easily, it will become possible to assemble a double floor structure simply and quickly. Moreover, since the connection position of a connection member can be moved up and down along a bolt accommodation groove | channel, it becomes possible to change the dimension and shape of a double floor structure easily.

なお、「上床構成材」には、床パネルなどの面状の部材だけでなく、梁材などの棒状の部材も含まれる。 The “upper floor constituent material” includes not only a planar member such as a floor panel but also a rod-shaped member such as a beam member.

本発明に係る二重床構造によれば、施工条件や需要者のニーズに低コストで対応することが可能となる。 According to the double floor structure according to the present invention, it is possible to respond to construction conditions and needs of consumers at low cost.
