Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明はスラブの構築方法に関するものである。[Detailed description of the invention] [Industrial application field] This invention relates to a method of constructing slabs.
従来スラブを軽量化するために中空ポイドエ法が採用さ
れている。該工法はコンクリートスラブ内に長尺鋼管等
を複数本埋設して、該鋼管内を中空にし、スラブの軽量
化するものである。Conventionally, the hollow poido method has been adopted to reduce the weight of slabs. This construction method involves burying a plurality of long steel pipes in a concrete slab, making the inside of the steel pipes hollow, and reducing the weight of the slab.
このような発明の問題点は鋼管等は一方向に埋設される
ため、スラブ剛性が一方向になり床剛性が低下すること
である。The problem with such an invention is that since the steel pipes and the like are buried in one direction, the slab rigidity is unidirectional and the floor rigidity is reduced.
またスラブ配筋の施工法が困難であるという問題がある
。Another problem is that the method of constructing slab reinforcement is difficult.
この発明にかかるスラブの構築方法は、下型枠上に略半
球状の突出部を縦横に適宜間隔離して並べるよう設置し

材を配設して、その後コンクリートを打設するものであ
る。The method for constructing a slab according to the present invention is to install approximately hemispherical protrusions on a lower formwork so as to be spaced apart from each other by an appropriate distance vertically and horizontally, and to place the protrusions between adjacent protrusions slightly above the upper surface of the lower formwork. Reinforcing bars or PC steel materials are arranged horizontally in a lattice pattern, and reinforcing bars or PC steel materials are also arranged in a lattice pattern on the protrusion, and then concrete is poured.
以下、図に示す一実施例に基づきこの発明の詳細な説明
する。Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.
図において1は下型枠であって柱間に水平に架は渡しで
ある。下型枠1上には略半球状の突上部3が設けられて
いる。突出部3は鋼板、プラスチック、ダンボール、発
泡スチロール等の材料によって形成されている。In the figure, 1 is the lower formwork, and the frame is a bridge horizontally between the pillars. A substantially hemispherical projecting portion 3 is provided on the lower formwork 1. The protrusion 3 is made of a material such as a steel plate, plastic, cardboard, or expanded polystyrene.
突出部3は複数個が適宜間隔離れて縦横に配設して、ボ
ルト、接着材等によって下型枠1上に取付ける。A plurality of protrusions 3 are arranged vertically and horizontally at appropriate intervals and are attached to the lower formwork 1 with bolts, adhesive, or the like.
以上のように縦横に配設した突出部3.3間に鉄筋4若
しくはアンボンドPC鋼材を水平に配設する。該鉄筋4
は下型枠1上面よりも若干上にあって、隣り合う突出部
3,3間を縫うように格子状に配設する。この鉄筋4若
しくはアンボンドPC鋼材がスラブ下部を補強する。As described above, reinforcing bars 4 or unbonded PC steel materials are horizontally arranged between the protrusions 3.3 arranged vertically and horizontally. The reinforcing bar 4
are located slightly above the upper surface of the lower formwork 1, and are arranged in a grid pattern so as to thread between adjacent protrusions 3, 3. This reinforcing bar 4 or unbonded PC steel reinforces the lower part of the slab.
突出部3の頂部よりも若干上にも同じく鉄筋5若しくは
アンボンドPC鋼材を縦横に水平な格子状に配設する。Slightly above the top of the protruding portion 3, reinforcing bars 5 or unbonded PC steel materials are similarly arranged in a horizontal and vertical grid pattern.
この鉄筋5若しくはアンボンドPC鋼材はスラブの上部
を補強する。This reinforcing bar 5 or unbonded PC steel reinforces the upper part of the slab.
以上のような下型枠1上にコンクリート6を打設してス
ラブを構築する。A slab is constructed by pouring concrete 6 onto the lower formwork 1 as described above.
コンクリート6硬化後突出部3とともに下型枠1を脱型
する。突出部3は縦横に並べであるため、突出部3,3
間のコンクリート6は縦横に連続するとともに、その中
に鉄筋4が配筋され二方向のスラブ剛性を有することに
なる。After the concrete 6 hardens, the lower formwork 1 is removed together with the protrusion 3. Since the protrusions 3 are arranged vertically and horizontally, the protrusions 3, 3
The concrete 6 in between is continuous in the vertical and horizontal directions, and reinforcing bars 4 are arranged therein to provide slab rigidity in two directions.
この発明は以上のような構成を有するが、下型枠1を鋼
製にすれば鉄骨梁に溶接固定して使用してもよい。この
場合は下型枠1は脱型しない。Although the present invention has the above configuration, if the lower formwork 1 is made of steel, it may be used by being welded and fixed to a steel beam. In this case, the lower formwork 1 is not demolded.
下型枠1を鋼製にして突出部3を一体に成形してもよい
。The lower formwork 1 may be made of steel and the protrusion 3 may be integrally molded.
また突出部3を生卵型にして矛5図に示すようなスラブ
を構築してもよい。Alternatively, the protrusion 3 may be shaped like a raw egg to construct a slab as shown in Figure 5.
この発明は以上のような構成を有し、下型枠上に略半球
状の突出部を縦横に適宜間隔離して並べるよう設置し、
該隣接する突出部間であって下型枠上面より若干上に水
平に鉄筋若しくはpc鋼材を格子状に配設するとともに
、且つ前記突出部上にも格子状に鉄筋若しくはpc鋼材
を配設して、その後コンクリートを打設するものである
。The present invention has the above-described configuration, in which approximately hemispherical protrusions are installed on the lower formwork so as to be spaced apart from each other at appropriate intervals vertically and horizontally, and
Reinforcement bars or PC steel materials are arranged horizontally in a grid pattern between the adjacent protrusions and slightly above the upper surface of the lower formwork, and reinforcing bars or PC steel materials are also arranged in a grid pattern on the protrusion parts. After that, concrete is poured.
従って突出部の分だけコンクリートの量が低減して、ス
ラブ全体の重量を軽くすることができる。Therefore, the amount of concrete is reduced by the amount of the protruding portion, and the weight of the entire slab can be reduced.
突出部間のコンクリートは縦横に連続するとともに、そ

方向性スラブとして床剛性が増大し、床振動を押え、防
音、遮音効果も良好となり、スラブの大型化も可能とな
る。The concrete between the protruding parts is continuous vertically and horizontally, and reinforcing bars or PC steel are arranged within it, so the floor rigidity increases as a bidirectional slab, suppresses floor vibration, and has good soundproofing and sound insulation effects. , it is also possible to increase the size of the slab.
pc鋼材を使用して本発明のように上下に配設すれば、
フラットなスラブに比べてライズが大きくとれるので懸
垂力も大きく、pc鋼材の本数も少なくすることができ
る。If PC steel is used and arranged vertically as in the present invention,
Compared to a flat slab, the rise can be larger, so the suspension force is greater, and the number of PC steel members can be reduced.
突出部もユニット化すれば軽量化が図れ、運搬、施工も
容易となる。If the protruding parts are also made into units, it will be lighter and easier to transport and install.
