する工法は現在多〈実施されている。In the deck slab construction method for reinforced concrete construction, steel frame construction, and steel/reinforced concrete construction, deck plates can be used as formwork to eliminate the troublesome work of temporary materials in the current construction method that uses formwork and temporary reinforcing materials. Currently, there are many methods of constructing a deck slab by integrating the deck plate with poured concrete.

いものである。However, according to this conventional construction method, as shown in Figures 1 and 2, the first deck plate 1 is placed between the beams and fixed to the steel beam 2 by single welding 3, and then concrete is poured. At this time, close the edges of the deck plate 4 to prevent concrete from flowing down, weld the stud dowel 5 to the steel beam 2, fix the reinforcing bar net 6 to the deck plate with spacers 7, and then close the steel beam. The joint part 8 of the adjacent reinforcing bar net at the top is treated by overlapping a narrow and long reinforcing bar net 9, and then concrete 10 is poured to construct the floor slab a, so all the work is done on site. Since it is a field work that requires assembly one by one, it is difficult to say that the workability is necessarily good.

具体例を示した図面について説明する。Similar to the above construction method, the present invention uses a deck plate as a formwork, in which each member is integrated in advance using a factory production method to form a large-span floor slab panel.
It is characterized by the fact that concrete can be poured by simply suspending the slab panel using a mounting device, dropping it into the opening of the slab, placing it on a beam, and securing it with welding.The purpose is to replace the conventional construction method. The purpose of this invention is to provide a new floor slab construction method that can significantly reduce on-site work, improve workability and efficiency, and ensure work safety.The following are drawings showing specific examples of the present invention. I will explain about it.
本発明は先づ床版パネルBを予め工場において先組み形

1. The flat plate part 13 is attached to each beam of the floor slab opening formed by being surrounded by the beams 12 installed between the vertical plate parts 14 and 12. A steel material 16, such as a Z-shaped steel, is formed by forming an oil film on the plate part 15 from the lower end of the plate part 14 in a direction symmetrical to the flat plate part, and a frame is formed roughly corresponding to the deck opening, and a deck plate 17 is inserted therein. is supported on the plate part 15, and the plate part 15 and the peripheral part of the deck plate are fixed by welding 18, and the deck plate edge 19 is fixed.
is closed by the vertical plate part 14.
又上記鋼材16は、予め床版開口部に対応するスパンに
形成させたデツキプレートの周縁部に溶接により固定し
てもよい。Further, the steel material 16 may be fixed by welding to the peripheral edge of a deck plate that is previously formed to have a span corresponding to the deck opening.
鉄筋は予め溶接した鉄筋網20を使用するもので、該鉄
筋網20は、スペーサー21でデツキプレートに固定さ
せて床版開口部すに対応した任意単位面積の床版パネル
Bを構成する。As the reinforcing bars, a pre-welded reinforcing bar network 20 is used, and the reinforcing bar network 20 is fixed to the deck plate with spacers 21 to constitute a floor slab panel B having an arbitrary unit area corresponding to the floor slab opening.
上記スペーサー21は、スプリング網板を中央部から彎

平行に固定し一体化させるものである。The spacer 21 has a spring net plate curved from the center to form a holding portion 22 in the center, and each end portion 23
, 23 are formed by protruding outwardly from the left and right side edges of the reinforcing bars 24 and 23, and the reinforcing bars are sandwiched and held in the holding parts to support the reinforcing bar net, and as shown in FIG. Part 23,
23 into the trough 17a of the deck plate 17, and hooked the claw pieces to the left and right side walls 17b of the trough, fixing the reinforcing bar net to the deck plate in parallel with the surface of the plate at an appropriate distance, and integrating it. It is something that makes you
又上記網材16の適宜位置には、フック等で吊シ下げ易
くする為に吊り孔25……を任意数設けておくとよい。Further, it is preferable to provide an arbitrary number of hanging holes 25 at appropriate positions of the net material 16 to facilitate hanging with a hook or the like.

一個の床版開口部に対応して設けられるが、床版開口部
が特別大スパンである場合は、二個又は三個の床版パネ
ルを使用するように予めその床版パネルを形成させたも
のであってもよい。Generally, the floor slab panel B having the above configuration is as described above.
It is provided corresponding to one floor slab opening, but if the floor slab opening has an extra large span, the floor slab panel is formed in advance so that two or three floor slab panels are used. It may be something.
而して本発明の施工法は、上記のように予め工場で先組
みした床版パネルBを現場へ搬入し、クレーン等の架装
装置で吊り下げ位置合せした后、床版開口部すに落し込
み鋼材の平板部13を梁12上に乗せて掛止し、床版開
口部へ架設保持させる。According to the construction method of the present invention, the floor slab panel B, which has been assembled in advance at a factory as described above, is carried to the site, and after being suspended and aligned using a mounting device such as a crane, the floor slab panel B is installed at the opening of the floor slab. A flat plate part 13 of dropped steel material is placed on the beam 12 and hooked, and is constructed and held at the opening of the floor slab.
この状態で床版パネルは各梁間に落し込まれて梁に鋼材
の垂直板部が突き当り、横方向へのずれは阻止される。In this state, the floor slab panel is dropped between each beam, and the vertical steel plates abut against the beams, preventing it from shifting in the lateral direction.
次に鋼材16の例えば平板部と梁12を第4図例示した
如く溶接26し、床版パネルBを構造体に固定する。Next, for example, the flat plate portion of the steel material 16 and the beam 12 are welded 26 as illustrated in FIG. 4 to fix the floor slab panel B to the structure.

床版30を構築する。After that, the stud dowel 27 is welded to the beam, and the reinforcing bar network of that floor slab panel is connected to the reinforcing bar network of the adjacent floor slab panel, which has been dropped and fixed into another floor slab opening in the same manner as above. A narrow and long reinforcing bar net 28 is superimposed on the part C, the joint part i of the reinforcing bar net is processed, and concrete 29 is poured.
Build the floor slab 30.
尚上記梁12は鉄骨構造を図示したが、本発明はこれに
限定的であることはなく、他に鉄筋コンクリート梁、鉄
骨鉄筋コンクリート梁であってもよく、このような場合
は梁に予め溶接の為の鉄筋等を先付けしておき、これと
上記床版パネルの鋼材を溶接して固定するとよい。Although the above-mentioned beam 12 has a steel frame structure, the present invention is not limited to this, and may also be a reinforced concrete beam or a steel reinforced concrete beam. It is recommended to attach reinforcing bars etc. in advance and weld these to the steel material of the above-mentioned floor slab panel.
以上のように本発明の床版施工法によれば、床版構成部

ト打ちを行なって床版を施工するから著しい作業の迅速
化と省力化がはかれる。As described above, according to the floor slab construction method of the present invention, a floor slab panel is formed by assembling the floor slab constituent members in advance through factory production, and the floor slab panel is hung at the site to open the floor slab opening. After the slab is lowered, it is welded to the beam, and then concrete is poured and the slab is constructed, which greatly speeds up the work and saves labor.
更に床版パネルを床版開口部へ落し込む簡単な現場作業
で一度に大スパンを能率的に施工し得ることは機械力を
使用した安定した状態に保持されるから、該床版パネル

溶接個所も少ない上にデツキプレートの小口塞ぎ作業が
省け、又鉄筋網は工場で堅牢に一体化出来、床版の施工
性及び施工精度を格段に向上できる等の利点がある。Furthermore, it is possible to efficiently construct large spans at once by simply dropping the floor slab panels into the floor slab openings, and since the floor slab panels can be maintained in a stable state using mechanical force, it is easy to work on the floor slab panels. As a scaffold, for example, welding and other work can be performed safely even under strong winds, and since the steel material 16 is wrapped around the deck, there are fewer welding points and the work of closing the edge of the deck plate can be omitted, and the reinforcing bar net is sturdy at the factory. It has the advantage of being able to be integrated into the floor slab, significantly improving the workability and accuracy of the floor slab.
従って本発明の施工法実施層は、床版工事は工期短縮、
省力化及び作業の安全化等建築業界への貢献度は極めて
大きいものである。Therefore, the implementation layer of the construction method of the present invention is to shorten the construction period for floor slab construction,
The contribution to the construction industry, such as labor saving and work safety, is extremely large.
