Description
【発明の詳細な説明】 「産業上の利用分野」 本発明は、梁用型枠に関するものである。[Detailed description of the invention] "Industrial application field" The present invention relates to a formwork for a beam.
「従来の技術と発明が解決しようとする問題点」
従来、鉄骨鉄筋コンクリート造における型枠工
事は、底と両側のせき板を桟木で固め、ばた材、
根太、支柱等から成る支保工で支持している。``Problems to be solved by conventional technology and the invention'' Conventionally, formwork work for steel-framed reinforced concrete construction involves hardening the bottom and both sides of the weirs with crosspieces,
It is supported by shoring consisting of joists, pillars, etc.
しかし、斯様な型枠工事は、かなりの手間、暇
がかかり、組立て、解体が容易でない。また、支
保工の支柱が林立して、他の各種作業に支障を来
すため、支保工を出来るだけ少なくすることが要
望され、種々の工夫がなされている。 However, such formwork work requires considerable time and effort, and assembly and disassembly are not easy. In addition, since the pillars of the shoring stand in a row and interfere with various other works, it is desired to reduce the number of shoring as much as possible, and various measures have been taken.
その一つに、大梁鉄骨から吊りボルトを垂設し

吊り型枠がある（特公昭49−33131号公報、特公
昭53−15290号公報、特開昭60−242256号公報）。 One of them is a so-called hanging formwork in which hanging bolts are hung from the girder steel frame and the girder formwork is supported by the hanging bolts (Japanese Patent Publication No. 49-33131, Japanese Patent Publication No. 53-15290, Publication number 60-242256).

短縮できない。 However, all the formwork members still have to be removed after construction because the supports simply cannot stand, and in this case, the concrete compressive strength on the beam side is 50%.
It can be removed if it reaches Kg/cm 2 or more, but under the beam,
Since it cannot be removed unless the concrete compressive strength exceeds the design standard strength, the construction period cannot be shortened much in the end.

リート造の建物には適しない。 Furthermore, even if it were possible to shorten the construction time for the large beams, there is a problem with how to link the formwork for the small beams, and unless this problem is also resolved, shortening of the construction period cannot be expected. In addition, the small beam
You can use truss beams, lattice beams, etc.
-34782 Publication), it is suitable for steel-framed buildings that do not require high strength, but is not suitable for steel-framed reinforced concrete buildings that require high strength.

In addition, we aim to shorten the
The aim is to improve safety.

から成る。"Means for solving the problem" Hanging bolts are appropriately hung from the bottom of the girder steel frame, a receiving member is suspended by the hanging bolt, and the girder bottom corrugated steel plate is supported by the receiving member, and
A formwork for the girder supported the weir plates on both sides facing each other, and a small beam plate formed with a U-shaped cross section from corrugated steel plate was installed.The small beam plate was supported by a reinforcing frame, and the reinforcing frame was and a small beam formwork, the end of which is supported by the upper edge of the weir plate of the large beam formwork, and connected to the large beam steel frame via welded metal fittings.

Angle materials or the like will be used as the receiving members, and these will not be removed later, but will remain attached, and only the formwork on the sides of the girders will be removed. It is advisable to provide a column in the center of the girder formwork to prevent deflection.

せることができる。"Effects of the Invention" According to the present invention, the girder formwork suspends the receiving member from the girder steel frame via the suspension bolt, supports the girder bottom corrugated steel plate with the receiving member, and supports the girder bottom corrugated steel plate, and also supports the weir plates on both sides facing each other. In addition, the formwork for the small beam supports a small beam plate formed with a U-shaped cross section by a corrugated steel plate with a reinforcing material, supports the reinforcing material with an aust, and supports the end of the aust. Since it is supported on the upper edge of the sheir plate of the girder formwork mentioned above and connected to the girder steel frame via welded hardware, it is possible to build a high-strength steel-frame reinforced concrete building with integrated reinforced concrete girders without any problems. Not only can it be constructed, but the formwork for the girders and the formwork for the small beams can be properly associated, and later, out of the entire formwork, only the weir plates on both sides of the girder formwork can be removed. Therefore, post-process work such as ceiling base work can be started quickly regardless of the removal of the formwork, and there is no need to dismantle the formwork.
Of course, it is possible to eliminate most of the supports of the shoring structure, there is no need to erect and remove the supports, and it is possible to eliminate the hindrance to various other works caused by the stand of supports. It can significantly shorten construction time, reduce costs, and improve work safety.

る。 Furthermore, it is particularly advantageous in places with high floors or where beams have slopes, and since there are no supports, wall formwork can be easily assembled and a sufficient safe passage can be secured.
