【考案の詳細な説明】 本考案は、片持スラブの外方に突出させる状態
で設けられる建設現場用のプラツトホームの改良
技術に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved technique for a platform for construction sites, which is provided in a state where the cantilevered slab projects outwardly.

例えばマンシヨン等の集合住宅の２棟を、一方
の棟の廊下側に他方の棟の妻側を位置させて、平
面視でＬ字状に隣接させて建設するような場合、
前記廊下を形成する片持スラブと妻壁の間の隙間
には、開口養生としてプラツトホームが配置され
る。 For example, when constructing two apartment buildings such as condominiums, with the hallway side of one building and the gable side of the other building adjacent to each other in an L-shape when viewed from above,
A platform is placed in the gap between the cantilevered slab and the gable wall forming the corridor to protect the opening.

に運ぶために、各階の廊下やバルコニーの外方に
ロングリフトを配置するが、このロングリフトと
廊下やバルコニーとの隙間にも開口養生用のプラ
ツトホームが配置される。 In addition, as construction progresses to the upper floors, long lifts will be placed outside the corridors and balconies of each floor in order to transport materials upwards, and the gaps between these long lifts and the corridors and balconies will also have openings for curing. The platform is placed.

を配置しているが、膨大な量の支柱を要すると共
に、これの撤去に際して多大の作業手間を要し、
のみならず非常に危険な高所作業を要し、早急な
る改善が待たれている状況にある。 Conventionally, in order to place a platform outside a cantilevered slab, the pillars are successively added upward and the platform is placed at a predetermined location on the pillars, but this method requires a huge amount of supports. At the same time, it requires a great deal of work and effort to remove it.
Not only that, but it also requires extremely dangerous work at heights, and the situation is in desperate need of improvement.

本考案は、この要望に呼応して成されたもので

る。 The present invention was developed in response to this demand, and is a platform for construction sites that includes a plurality of female threaded anchor members buried in a drainage groove at the tip of a cantilevered slab, and a plurality of female threaded anchor members. Clamp fittings each having a male screw member that is screwed into the clamp fittings, a support member that is clamped to each of the clamp fittings, and a plurality of the supporting members that are mounted on a portion that protrudes beyond the tip of the cantilever slab nose. The feature is that it is constructed from a plate-shaped body that is fixed in place.

に、該プラツトホームの撤去を片持スラブ上にお
いて行なえるものであるから、高所作業でありな
がらこれを安全に行なえるようになつた。 According to this characteristic configuration, it is possible to create a platform for opening curing of the required size only in the necessary location outside the cantilever slab, and moreover, it is possible to create platforms for opening curing of the required size only in the necessary locations outside the cantilevered slab, and moreover, platforms that are no longer needed on the lower floor can be used as they are on the upper floor. The platform can be converted into a floor, thereby reducing the number of platforms required, and the platform can be removed on a cantilevered slab, making it possible to work at heights safely. I started to do that.

そして、前記雌ねじアンカー部材は、片持スラ

に成し得るに至つたのである。 The female threaded anchor member may be provided at any location on the cantilever slab, but if it is left as is, it will not only look bad, but will also cause rust and the accumulation of rainwater, dirt, etc. Therefore, post-treatment to hide this is absolutely necessary, and in this invention, post-treatment (drain By applying mortar to the inner surface of the drainage groove to create a drainage slope), a female threaded anchor member was specifically provided at the bottom of the drainage groove. Therefore, the internally threaded anchor member is concealed by the mortaring work that is necessarily performed to create a drainage slope, making it possible to eliminate the need for special post-processing work for the member. It's ivy.
