本発明はコンクリートスラブの構築工法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a concrete slab.
従来ビル等のコンクリート建造物の建築工事において
、２階、３階等上層階の床スラブ（階下の天井スラブ）
を構築する場合には、粱等の間に型枠を張り渡してそれ
を支保工装置で支えた状態にし、当該型枠上で所定の配
筋作業を行つたのちコンクリート打設していた。In construction work for conventional concrete buildings such as buildings, floor slabs on upper floors such as the second and third floors (ceiling slabs on lower floors)
When constructing a concrete structure, a formwork was stretched between the blocks and supported by shoring equipment, and concrete was poured after the specified reinforcement work was performed on the formwork.
従つて構築に際しては必らず支保工装置の取付および
取外し作業が必要であるため工期を遅延させると共に、
この支保工装置の取外しは打設したコンクリートが硬化
する迄の期間（２〜３日）装用するにしても多数を用意
しなければならない。Therefore, during construction, it is necessary to install and remove shoring equipment, which delays the construction period and
Even if this shoring device is to be removed for a period of time (2 to 3 days) until the poured concrete hardens, a large number of supporting devices must be prepared.
又配筋およびコンクリート打設作業は足場を設けて不
安定な状態でおこなわれるので作業能率が低下すると共

保を計ることを実現せしめた新規なコンクリートスラブ
の構築工法である。In addition, reinforcing and concrete pouring work is performed in an unstable state using scaffolding, which reduces work efficiency and poses problems in ensuring safe work. Therefore, in order to solve the above-mentioned problems, the present invention drastically shortens the construction period by eliminating the need for any shoring, and also ensures safe work by performing reinforcement work on the already constructed floor slab. This is a new concrete slab construction method that makes it possible to measure

上下の壁パネルＢ相互とを一体に接合する。Then, concrete is poured for each slab structure A to construct a ceiling slab (floor slab on the upper floor), and concrete is also poured in the gaps between each slab structure to construct the adjacent slabs. The floor slabs and the upper and lower wall panels B including the beams C are integrally joined together.
そして天井仕上の外観を問題としない建造物の場合は捨
型枠のままでも良いが、その他の場合には捨型枠の下面
に仕上部材を添装する。In the case of a building where the appearance of the ceiling finish is not an issue, the blank form may be left as is, but in other cases, a finishing member is attached to the bottom surface of the blank form.

記工法による本発明は次のような優れた効果を奏するこ
とができる。As described above, the method of constructing a concrete slab according to the present invention is to assemble the hollow vibes as the main frame material and the reinforcing bars as the auxiliary frame material integrally on the waste formwork on the already constructed floor slab. A structure is created, the slab structure is erected between each beam via the hollow vibe, and each beam and the slab structure are integrally joined by pouring concrete into the slab structure. . The present invention using the above-mentioned construction method can produce the following excellent effects.
１予め組立てたスラブ構造体をそのまま梁間に架設する
ために支保工が不要となりその取付および取外し作業が
省略されて作業工期を短縮することができる。1. Since the pre-assembled slab structure is directly erected between the beams, no shoring is required, and the installation and removal work is omitted, thereby shortening the work period.
２配筋作業を床スラブ上で行うために作業性の向上と安
全作業の確保を計ることができる。2 Reinforcement work is performed on the floor slab, improving work efficiency and ensuring safe work.
３捨型枠のために型枠の取外し作業が不要である。Since the formwork is 3-disposable, there is no need to remove the formwork.
４主骨組材である中空バイブの強度が大きいために補助
骨組材としての鉄筋が少なくてすむと共に、中空のため
にコンクリート使用量も少くて経済的てあり、しかも軽
量であること。4.Since the strength of the hollow vibrator, which is the main frame material, is strong, less reinforcing steel is required as an auxiliary frame material, and since it is hollow, the amount of concrete used is small, making it economical and lightweight.
