Abstract
Description
本発明は中高層鉄筋コンクリートの複数階の天井スラブの型枠(コンパネ)に略1度に生コンクリートを投入する天井スラブ施工法及びその装置に関するものである。 The present invention relates to a ceiling slab construction method and apparatus for putting ready-mixed concrete into a form of a ceiling slab on a plurality of floors of medium- and high-rise reinforced concrete approximately once.
従来、中高層鉄筋コンクリート建築物の施工に際し、天井スラブの施工は型枠(コンパネ)代わりになるプレキヤスコンクリート板材を予め架設したプレキヤスト桁行き梁にクレーンで吊って上方から躯体内に取り込み、支保工無しで天井スラブの施工を行うものであった(例えば特許文献1)。 Conventionally, when constructing medium- and high-rise reinforced concrete buildings, ceiling slabs are constructed by pre-casting girder beams pre-installed with pre-cast concrete plates that can be used as a substitute for the formwork (panel). The construction of ceiling slabs was performed (for example, Patent Document 1).
このような施工法による建築物は規格性に優れて良いが、桁行き梁及び天井スラブを量産する必要があり、坪量の減少、設計の単一性、設計の面積の減少及びそれに伴う耐震性に問題があった。 Buildings based on such construction methods may be excellent in standardity, but it is necessary to mass-produce girder beams and ceiling slabs, which reduces basis weight, unity in design, decreases in design area, and associated earthquake resistance. There was a problem with sex.
又、大形の中高層建築では比較的長い大引材及び根太により比較的広い天井スラブが多数の支保工により施工され天井スラブ施工にはコンクリートの硬化、凝固に時間を要した(例えば特許文献2)。 Further, in a large medium- and high-rise building, a relatively wide ceiling slab is constructed by a large number of supporting works due to a relatively long large drawing material and joists, and it takes time to harden and solidify the concrete (for example, Patent Document 2). ).
しかし、天井スラブの広さ、厚さを自由に設計できるが、各床の天井スラブのコンクリート硬化、凝固に時間を要した。 However, the width and thickness of the ceiling slab can be designed freely, but it took time to harden and solidify the concrete of the ceiling slab on each floor.
本発明は比較的広く厚い鉄筋コンクリートによる中高層建築物の生コンクリートによる天井スラブの硬化・凝固施工時間を略1/2に短縮することを目的とする。 An object of the present invention is to shorten the time required for hardening and solidifying a ceiling slab made of ready-mixed concrete of a medium and high-rise building made of relatively wide and thick reinforced concrete to about ½.
