Abstract
(57)【要約】
【目的】 デッキプレートに直接、ダクトを設置する。
【構成】 ダクト（１）とその内側を移動できるフラン
ジ（２）と、固定されたフランジ（３）で構成される。
(57) [Summary] [Purpose] The duct is installed directly on the deck plate. [Structure] The duct (1) is composed of a flange (2) movable inside the duct (1) and a fixed flange (3).
Description
【０００１】[0001]
この考案は、建築工事に於いて、コンクリート打設前におこなう床の開口に関 するものである。 The present invention relates to the opening of the floor before the concrete is placed in the construction work.
【０００２】[0002]
従来、スリーブ入れ作業において、デッキプレート上にダクト寸法より大きい 木枠を作ってコンクリートを止めていた。 Conventionally, in the sleeve insertion work, a wooden frame larger than the duct size was made on the deck plate to stop the concrete.
【０００３】 これは次のような欠点があった。 （イ） 木枠はコンクリート打設後取り除かねばならず、材料も無駄になる。 （ロ） 実際のダクト寸法より、床の開口が大きくなるので、すきまを埋めな ければならない。 本考案は、これらの欠点をのぞくためになされたものである。This has the following drawbacks. (B) The wooden frame must be removed after the concrete is placed, and the materials are wasted. (B) Since the floor opening is larger than the actual duct size, the clearance must be filled. The present invention has been made to eliminate these drawbacks.
【０００４】[0004]
デッキプレート上に固定したダクト（１）の内側に上下移動のできるフランジ （２）を入れる。コンクリート打設後デッキプレートを開口するときは、フラン ジ（２）を上に移動すれば作業の支障にならない。 デッキプレート開口後、フランジ（２）を底面まで下げ、溶接等でダクトと接 合する。 Insert a vertically movable flange (2) inside the duct (1) fixed on the deck plate. When opening the deck plate after placing concrete, move the flange (2) upward so that it will not hinder the work. After opening the deck plate, lower the flange (2) to the bottom and connect it to the duct by welding, etc.
【０００５】[0005]
埋設されたダクトの上下には他のダクトとの接続用フランジがあるので、その まま接続できる。 Since there are flanges for connecting to other ducts above and below the buried duct, they can be connected as they are.
【０００６】[0006]
ダクト周囲に軽量等辺山形鋼で補強し、固定用ビス穴をあけるとよい。 It is advisable to reinforce the periphery of the duct with lightweight equilateral angle steel and open fixing screw holes.
【０００７】[0007]
作業能率が向上し、開口部もきれいになった。 The work efficiency has improved and the openings have been cleaned.
