この発明は、新規な鉄筋コンクリート壁の開口設置工法
の提供に係わる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the provision of a novel method for installing openings in reinforced concrete walls.

開口を設置する場合がある。Recently changed its use to reinforced concrete walls of condominiums etc.
C-J-,) There are cases where reinforced concrete walls are removed and new openings are installed, such as the installation of new entrances and exits and openings for pipes for heating and cooling.

モンドカッターによるのが現状である。In this case, in order to prevent vibration and noise, relatively large openings are currently constructed using a hand-folding method or a special hydraulic crusher, while small openings for pipes are currently constructed using a diamond cutter.
しかし、斜上の工法は、コスト及び作業性等に問題があ

があり、その周辺に飛び散る水の処理等問題が多い。However, the diagonal construction method has problems in terms of cost and workability, and especially in the case of a diamond cutter, it is necessary to use water, and there are many problems such as the disposal of water that scatters around the cutter.
また、いずれの場合も専門業者によっている。In both cases, the work is done by a specialist.

としたものである。The present invention was developed in view of the problem of diagonal slopes, and its gist is to cut out a predetermined opening from the concrete surface using a carpenter's saw cutter along the markings of the planned opening on the wall surface. Make a cut in depth on one side only, then fill the cut with an expanding material for crushing, and expand the cut due to the volumetric expansion of the expanding material, causing a crack to reach the opposite side, and then make a crack along the crack. hammer and ib
By removing the concrete wall with a chisel to open the opening, an amateur can easily install the opening using a simple tool, and this also reduces costs and simplifies the work.

It is possible to save labor without having to use manpower, and as a result, there is a significant cost reduction (currently 10,400 yen / φ200~, wall thickness 200 mm)
However, with this construction method, the cost can be reduced to about 5'000 yen/place. Another advantage is that the shape of the opening can be made relatively freely.
