Abstract

To solve the problems: (1) the conventional method of assembling a slab with a flutter angle is based on a slab with a fluttering angle of 90 mm square, which requires heavy labor, requires fine technique, and takes a long time to train an engineer, and therefore, young people are shunned and the shortage of successors is serious; (2) wood corrodes, which costs to dispose of industrial waste; and (3) the forests of the earth have decreased by the equivalent of Japan's land area in two years, and thus in order to overcome the above problems, the present invention aims at simplifying the assembly of formwork with steel screws and reducing labor, enabling short-term training of assembly engineers, and can contribute to solving the problem of successor shortage in the industry and the problem of declining birthrate and aging population.SELECTED DRAWING: Figure 2

Description

本発明は、建設業等のコンクリート型枠の組み立ての合理化促進に関するものである。 The present invention relates to promoting rationalization of assembly of concrete formwork in the construction industry and the like.

従来、建設業等のコンクーリト型枠の組み立ては、場所によって、バタ角で組み立てるのが一般的である。 Conventionally, when assembling a concool formwork in the construction industry or the like, it is common to assemble with a flutter angle depending on the location.

図解建築の型枠工事（理工学社、畑中和穂著）Formwork work for illustrated architecture (written by Rikogakusha Publishing Co., Ltd.

従来の工法は、次のような欠点があった。
（イ）バタ角の接手加工に手間がかかる。
（ロ）バタ角は断面が９０ｍｍ×９０ｍｍになって運搬、積み置き整理の効率が悪い。
（ハ）接手組み立て技術が複雑で微細な技術を要し、技術習得に長期間を要する。
（ニ）転用効率が悪い。
本発明は、以上の問題点を解決するために発明されたものである。The conventional construction method has the following drawbacks.
(B) It takes time and effort to joint the flutter angle.
(B) The flutter angle has a cross section of 90 mm × 90 mm, and the efficiency of transportation and stacking arrangement is poor.
(C) The joint assembly technology is complicated and requires fine technology, and it takes a long time to acquire the technology.
(D) Diversion efficiency is poor.
The present invention has been invented to solve the above problems.

課題を解決するためバタ角を一切使わず、リップ溝形鋼（以下、Ｃチャンと云う）２本合せをスラブの大引に用いる。
そのための大引受金具を効果的に用いる。In order to solve the problem, no flutter angle is used, and a combination of two lip channel steels (hereinafter referred to as C-chan) is used for the slab pulling.
Effectively use large underwriting metal fittings for that purpose.

本発明を使用することによって、加工、組み立ての手間が省け、運搬、積み置き整理の作業能率を高め、組み立ての単純化で、短期間で組み立て技術が習得できる。By using the present invention, the labor of processing and assembling can be saved, the work efficiency of transportation and stacking and organizing can be improved, and the assembling technique can be learned in a short period of time by simplifying the assembling.

本発明を実施するための形態A mode for carrying out the present invention

以下、本発明の実施の形態を説明する。
（イ）鉄板（１）の要所に転倒防止用のビス孔（２）４ｍｍを明けたクランク型鉄板を、大引受金具に用いるべく、接合にφ２５のゴムホースを用いて２枚を１組として大引受金具を作る。
（ロ）スラブを張る所定位置にサポートをコンクリートビスで直立固定し、高さを調整して、サポートの上に大引受金具を取付て大引Ｃチャンものせて、根太を並べる。
（ハ）スラブの張方はツナギ鉄板利用を原則としジョイントは根太Ｃチャンからビスどめする、壁、梁との組方はスラブコンパネに角用鉄板を１２バックして＠３００位で付け、梁、壁へのスラブから梁、カベへの釘打は＠６００位として角鉄板からのビスどめに重きをおく。Hereinafter, embodiments of the present invention will be described.
(B) A crank-type iron plate with a screw hole (2) 4 mm for preventing falls at the key points of the iron plate (1) is used as a large underwriting bracket, and a rubber hose of φ25 is used for joining as a set of two. Make a large underwriting bracket.
(B) Fix the support upright with concrete screws at the predetermined position where the slab is to be stretched, adjust the height, attach the large underwriting bracket on the support, attach the large underwriting C-chan, and line up the joists.
(C) As a general rule, the slab should be stretched using a tsunagi iron plate, and the joint should be screwed from the joist C-chan. For nailing from slabs to beams and walls to beams and walls, place importance on screwing from square iron plates as @ 600.
