【考案の詳細な説明】
この考案はサツシ先付工法に於ける型枠に関す
る。[Detailed description of the invention] This invention relates to formwork in the sash tipping method.
サツシ先付工法は、省力化の一環として最近多
くの現場で採用されてきているが、工期短縮、労
働力の節減という目的をほゞ達成している反面、
品質および精度の低下をきたしている。 The Satsushi tip construction method has recently been adopted at many construction sites as part of labor-saving efforts, but while it has largely achieved its goals of shortening construction times and saving labor, it
This results in a decrease in quality and accuracy.
従来、用いられるサツシ先付工法における型枠
は建物躯体の内外壁間開口を一つの型枠で構成
し、その外周に開口枠を配するものであるため、
硬化したコンクリートの開口部から型枠を抜取る
のが困難であり、型枠を変形させたり、木製型枠
のような場合は全く破壊して取除いており、一窓
限りであり、金属型枠の場合も、一現場限りで大
幅な補修を要する。そして型枠を外す際にコンク
リートを破損し易いという欠点があり、型枠を外
すために多大の時間を消費している。 Conventionally, the formwork used in the sash tip construction method consists of a single formwork for the opening between the interior and exterior walls of the building frame, and the opening frame is placed around the outer periphery of the formwork.
It is difficult to remove the formwork from the opening in the hardened concrete, and the formwork is deformed, or in the case of wooden formwork, it is completely destroyed and removed. In the case of frames, extensive repairs are required at one site only. Another disadvantage is that the concrete is easily damaged when the formwork is removed, and a great deal of time is consumed in removing the formwork.
このようなサツシ先付工法に於ける型枠の問題
点を解決するため開口部に用いるコンクリート型
枠を見込方向の垂直又は水平な仕切り面にて分割
しており、型枠の解体が容易で運搬が楽であり、
各寸法の窓に融通して用いることができる特徴を
有する。 In order to solve this problem with formwork in the sash tip construction method, the concrete formwork used for the opening is divided by vertical or horizontal partition planes in the direction of projection, making it easy to dismantle the formwork. It is easy to transport,
It has the feature that it can be used flexibly for windows of various sizes.
これらの分割した型枠は分割して小さくして運
搬できる便がある一方、部品点数が多くて管理に
手間がかゝり、組立時間もかなり必要である。
又、開口部は対称でコンクリート型枠も左右対称
なものが多用されているため組付に融通性があ
り、それにもかゝわらず左右を入れ違えるとボル
ト穴加工位置精度がよくないために組立困難を来
たし、型枠精度がよくないと左右入違えると組立
つた型枠精度が悪く開口部が正確に仕上らないと
いう問題点がある。 Although these divided formworks can be divided into smaller pieces and transported, they require more time and effort to manage due to the large number of parts, and require a considerable amount of time to assemble.
In addition, the openings are symmetrical and the concrete formwork is often symmetrical, allowing for flexibility in assembly.However, if the left and right sides are inserted incorrectly, the accuracy of the bolt hole machining position will be poor. It is difficult to assemble, and if the formwork is not accurate, there is a problem that if the left and right sides are inserted incorrectly, the assembled formwork will not be accurate and the opening will not be finished accurately.
この考案は以上のサツシ先付工法に於ける分割
した型枠における問題点を解決し、型枠の組立が
容易であつてしかもコンクリート型枠が脱型後も
分散せず、脱型作業が分割したコンクリート型枠
と同等のものを提供しようとするものである。 This invention solves the problems of the divided formwork in the above-mentioned sash tip construction method, and makes it easy to assemble the formwork, and the concrete formwork does not scatter even after demolding, and the demolding work is divided into parts. The aim is to provide something equivalent to concrete formwork.

7 in the outward direction, the bolt nut 36 slides through the elongated hole 58. Then, when the upper formwork 3-1, the lower formwork 3-2, and the vertical formworks 3-3 and 3-4 are moved inward, the bolt nuts 36 slide inside the elongated holes 59,
The supporting members 43 and 43' are guided by the bolts and nuts 45, and the elongated holes 57 slide into the respective formworks,
It will look like Figure 12. And corner formwork 3-1
When 3, 3-14, 3-23, and 3-24 are removed from the mold and moved toward the center of the inside of the mold, the arm 41 slides through the long hole 56 using the bolt nut 45 as a guide, as shown in FIG. That is, the bolt/nut 45 is in an immovable position. The bolt/nut 45 occupies a fixed position as in the previous embodiment.

The upper and cross-shaped support rods can be attached to and removed from the brackets fixed to the upper and lower vertical formwork at the ends, and the brackets of the upper and lower vertical formworks can be attached to and removed from two positions, so when removing the formwork and assembling it. Vertical and horizontal supports are used again. An arm is installed obliquely from a corner formwork and extends into the formwork, and a support member is extended from the ends of the vertical formwork to cross over and into the formwork, so that the arm and the two support members intersect at one point. Since the molds are fastened at that point, the relative positions between the formworks are accurately determined, and the concrete placement pressure applied to the corner formworks can be resisted. Even in a position where the upper and lower vertical forms are arranged in a smaller rectangular shape than when assembled and the inner peripheral surface of the corner form is placed against the outer periphery of these ends, the arm support members intersect at one point, so the bolt holes are inserted at that position. By providing and fastening the concrete formwork, the entire formwork can be fastened after dismantling the concrete formwork.
