Description

本発明は、桁などの上に複数のパネルを設置して形成する床の構造に関するものである。
The present invention relates to a floor structure formed by installing a plurality of panels on a girder or the like.

H型鋼材などの桁材を間隔を置いて配置して構築した桁b上に床を形成する場合、矩形に製作したプレキャストコンクリートパネルaを桁b間に掛け渡す方法が従来から頻繁に実施されている(図4参照)。
従来のパネルaには内部にずれ止め孔cが複数設けてあり、桁bに取り付けたジベルdをずれ止め孔cに通し、ずれ止め孔cにコンクリート等の固化材を充填して、桁bとパネルaを結合していた。この結合構造によれば、パネルaが水平方向に移動することを制限するのも、上方に跳ね上げることを制限するのも、ずれ止め孔cに充填された固化材とジベルdが負担することになる。
When forming a floor on a girder b constructed by arranging girder materials such as H-shaped steel materials at intervals, a method of hanging a precast concrete panel a manufactured in a rectangular shape between the girder b has been frequently practiced. (See FIG. 4).
The conventional panel a is provided with a plurality of anti-slip holes c, and the gibber d attached to the beam b is passed through the anti-slip hole c, and the anti-slip hole c is filled with a solidifying material such as concrete, and the beam b And panel a. According to this coupling structure, the solidified material and the gibber d filled in the stopper hole c bear the burden of restricting the movement of the panel a in the horizontal direction and restricting the panel a from jumping upward. become.

前記した従来の複数のパネルを使用した床の構造にあっては、次のような問題点がある。
<1>車両の通行などによって床に大きな活荷重が繰り返し作用した場合、ずれ止め孔cに設けた結合部に正負の繰り返し応力が発生する。しかし、コンクリート等の硬質の固化材では、床(パネルa)の変位、または回転に追随できず、充填した固化材が徐々に劣化、損傷していくという問題がある。
<2>結合部が劣化すると、水みちが形成され、桁などが腐食する原因となる。
<3>ずれ止め孔cは一枚のパネルaに複数設けてあるため、パネルaの設置時に位置合わせをすることが難しい。
<4>パネルaの一部が損傷した場合や床下のメンテナンスを行うときに、固化材で一体化されたパネルaを取り外すのは難しい。また、取り外しのときに固化材が損傷するため、再度パネルaを設置するときに、再び固化材を充填する必要がある。
The conventional floor structure using a plurality of panels has the following problems.
<1> When a large live load is repeatedly applied to the floor due to the passage of a vehicle or the like, positive and negative repeated stresses are generated at the joint provided in the detent hole c. However, a hard solidified material such as concrete cannot follow the displacement or rotation of the floor (panel a), and there is a problem that the filled solidified material gradually deteriorates and is damaged.
<2> When the joint portion deteriorates, a water channel is formed, which causes corrosion of the girders and the like.
<3> Since a plurality of anti-slip holes c are provided in one panel a, it is difficult to align the position when the panel a is installed.
<4> When part of the panel a is damaged or when maintenance is performed under the floor, it is difficult to remove the panel a integrated with the solidifying material. Further, since the solidified material is damaged at the time of removal, it is necessary to fill the solidified material again when installing the panel a again.

上記のような課題を解決するために、本発明の床の構造は、複数のパネルを敷設して形成する床の構造であって、複数のパネルと、前記パネルを支持する弾性支承と、前記パネルの横方向の移動を制限するもので、かつパネルを設置する前に形成した突起部と、からなり、パネルを突起部に固着しないで設置し、床の上面を、パネルの上面と、突起部の上面によって形成することを特徴としたものである。
In order to solve the above problems, the floor structure of the present invention is a floor structure formed by laying a plurality of panels, the plurality of panels, an elastic bearing supporting the panels, and limiting the lateral movement of the panel, and a projecting portion which is formed prior to installing the panels, Tona is, the panel was placed without sticking to the projections, the floor top surface, the top surface of the panel, It is characterized by being formed by the upper surface of the protrusion .

本発明の床の構造は、上記した課題を解決するための手段により、次のような効果の少なくとも一つを得ることができる。
<1>弾性支承によってパネルを支持するため、パネルの端部に発生する変位や回転を吸収することができる。このため、従来の剛結合部のように繰り返し載荷によって損傷し、水みちになることがない。
<2>パネルに作用する横方向の力に対しては、突起部で対向する。このため、横方向へのパネルのずれを防ぐことができる。すなわち、従来の結合部が鉛直力と水平力の両方に対応していたのに対して、弾性支承と突起部のそれぞれに抵抗機構を配分することによって、耐久性や施工性を向上させることができる。
<3>パネルは突起部に強固に固着されていないため、取り外し又は交換が容易である。
The floor structure of the present invention can obtain at least one of the following effects by means for solving the above problems.
<1> Since the panel is supported by the elastic bearing, it is possible to absorb displacement and rotation generated at the end of the panel. For this reason, unlike the conventional rigid coupling part, it is damaged by repeated loading and does not become a water channel.
<2> The lateral force acting on the panel is opposed by the protrusion. For this reason, the shift | offset | difference of the panel to a horizontal direction can be prevented. In other words, while the conventional coupling portion has been adapted to both vertical force and horizontal force, it is possible to improve durability and workability by allocating a resistance mechanism to each of the elastic bearing and the protruding portion. it can.
<3> Since the panel is not firmly fixed to the protrusion, it is easy to remove or replace.

以下、図面を参照しながら本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1>パネル
本発明の床の構造は、複数のパネル1を敷き並べて形成する。パネル1の平面形状は如何なる形状であってもよく、四角形(1c)、六角形、八角形(1a)などの多角形や、円、楕円などの曲線形の形状のパネルが使用できる。また、四角形の四隅を切り欠いた形状(1a)、四角形の四辺の中央付近を切り欠いた形状(1b)のパネルなどが使用できる。
パネル1は、コンクリート、鋼材、高分子樹脂材などで所定の形状に製作することができる。パネル1は、中実構造であっても、中空構造であっても、外殻構造であってもよい。
<1> Panel The floor structure of the present invention is formed by arranging a plurality of panels 1 side by side. The planar shape of the panel 1 may be any shape, and a panel having a polygonal shape such as a quadrangle (1c), a hexagon, or an octagon (1a), or a curved shape such as a circle or an ellipse can be used. Moreover, the panel of the shape (1a) which cut off the four corners of a quadrangle, the shape (1b) which cut off the vicinity of the center of the four sides of a quadrangle, etc. can be used.
The panel 1 can be manufactured in a predetermined shape using concrete, steel, polymer resin, or the like. The panel 1 may be a solid structure, a hollow structure, or an outer shell structure.

<2>弾性支承
弾性支承2は、パネル1を支持する部材である。弾性支承2は、パネル1の端部に発生する変位や回転を吸収させるために設置する。例えば、H型鋼材などで構成した桁4の上面に板状またはシート状の弾性支承2を敷設し、その上にパネル1の端部を載せる。また、予めパネル1の端部に弾性支承2を貼り付けておき、桁4の上面に設置することもできる。
弾性支承2には、例えばゴム板やゴムシートなどが使用できる。
<2> Elastic Support The elastic support 2 is a member that supports the panel 1. The elastic support 2 is installed to absorb the displacement and rotation generated at the end of the panel 1. For example, a plate-like or sheet-like elastic support 2 is laid on the upper surface of a girder 4 made of H-shaped steel, and the end of the panel 1 is placed thereon. Alternatively, the elastic support 2 can be attached to the end of the panel 1 in advance and installed on the upper surface of the girder 4.
For the elastic support 2, for example, a rubber plate or a rubber sheet can be used.

<3>突起部
突起部3は、設置したパネル1の横方向の移動を制限するために設ける。パネル1は、弾性支承2上に設置しただけでは、横方向に移動してずれるおそれがある。このようなパネル1のずれを防ぐために、例えば桁4上に固定した突起部3を設け、パネル1の移動を拘束または制限する。
突起部3は、例えば桁4の上面に固定したジベル31や穴開き鋼板を包み込むようにコンクリート等を打設して形成する。突起部3の強度は、パネル1に作用する水平力を基に算出することができる。突起部3の形状は、隣接するパネル1の端面の形状に合わせて形成する。
突起部3は、パネル1を設置する前に形成してもよいし、パネル1を設置した後に形成してもよい。パネル1を設置する前に突起部3を形成した場合は、パネル1を突起部3間に嵌め込むだけで簡単にパネル1を設置することができる。また、パネル1を設置した後に突起部3を形成する場合は、パネル1の端面が型枠となるため、突起部3を効率的に構築できる。
<3> Protruding portion The protruding portion 3 is provided in order to limit the lateral movement of the installed panel 1. If the panel 1 is merely installed on the elastic bearing 2, there is a possibility that the panel 1 moves and shifts in the lateral direction. In order to prevent such a shift of the panel 1, for example, a protrusion 3 fixed on the beam 4 is provided to restrict or restrict the movement of the panel 1.
The protrusion 3 is formed by, for example, placing concrete or the like so as to wrap a gibber 31 or a perforated steel plate fixed to the upper surface of the beam 4. The strength of the protrusion 3 can be calculated based on the horizontal force acting on the panel 1. The shape of the protrusion 3 is formed in accordance with the shape of the end face of the adjacent panel 1.
The protrusion 3 may be formed before the panel 1 is installed, or may be formed after the panel 1 is installed. When the projection 3 is formed before the panel 1 is installed, the panel 1 can be installed simply by fitting the panel 1 between the projections 3. Moreover, when forming the protrusion part 3 after installing the panel 1, since the end surface of the panel 1 becomes a formwork, the protrusion part 3 can be constructed | assembled efficiently.

<4>緩衝材
緩衝材5は、パネル1,1間に配置する間詰め材である。本発明の床の構造は、パネル1の端部の変位や回転を弾性支承2によって吸収させる構造であるため、パネル1,1間には隙間を設ける。緩衝材5はパネル1,1間のこの隙間を埋める部材で、パネル1,1の隙間から水が桁4に向けて浸入することを防ぐことができる。また、パネル1,1同士が衝突して、パネル1の端部に応力集中が起き、損傷することを防ぐことができる。
緩衝材5には、ゴム、ウレタン、発泡ウレタンなどの材料が使用できる。
<4> Buffer material The buffer material 5 is a filling material disposed between the panels 1 and 1. Since the floor structure of the present invention is a structure in which the displacement and rotation of the end of the panel 1 are absorbed by the elastic support 2, a gap is provided between the panels 1 and 1. The buffer material 5 is a member that fills this gap between the panels 1 and 1, and can prevent water from entering the girder 4 from the gap between the panels 1 and 1. Moreover, it can prevent that the panels 1 and 1 collide and stress concentration arises in the edge part of the panel 1, and it is damaged.
For the buffer material 5, materials such as rubber, urethane, and urethane foam can be used.
