なることがあつた。[Detailed description of the invention] The present invention relates to a support device for a drainage ditch formwork in a cantilevered slab, and the assembly and removal of the drainage ditch formwork can only be carried out from above the bottom formwork. The aim is to make this process easier and faster. Conventionally, for shoring the formwork for drainage ditches in cantilevered slabs, a separator that penetrates the formwork for the bottom side of the cantilevered slab and a wooden cone attached to both ends of this separator have been used. Assembling and removing the frame required work from both the top and bottom of the bottom formwork. Further, since a space is required above the formwork for the drain for installing the wooden cone, the formwork for the drain cannot be formed into a hollow shape, but must have an open top surface. Therefore, during concrete pouring, some of the concrete flowed onto the drainage ditch formwork, and the formwork could not be removed unless this concrete was scraped off.
本考案は、これらの従来欠点を解消したもので

用型枠を固定した点に特徴がある。 The present invention eliminates these conventional drawbacks, and the upper part of the formwork for the side surface of the nose of the cantilever slab is attached to the top of the formwork for the bottom side of the cantilever slab and the tip of the large joist that supports the joist placed on the bottom surface. It is characterized in that one end of the support metal fitting is fixed in a shape that bypasses the drain, and the formwork for the drainage ditch is fixed to the other end of the support metal fitting.
以下、本考案の実施例を図面に基づいて説明す

A metal nose tip side form 4 of the cantilever slab A is installed at a predetermined position of the lower form 1 to fix nails, etc., and a synthetic resin mold is placed at a certain distance from the form 4. A bracket 5a made of aluminum is nailed onto the formwork 1 for the lower surface. The bracket 5a has a support made of synthetic resin at its upper end.
It is the same as a. ) Insert the lower end of the spacer 5c fitted with the spacer 5b.

枠６に固定する。 Next, a metal formwork 6 for a drainage ditch is placed on the support 5b, while a horizontal rod portion 7a, a first vertical rod portion 7b rising from one end of the horizontal rod portion 7a, and an upper portion bent from the upper end thereof. The formwork 2 for the side surface of the nose is formed by the horizontal rod part 7c, the second vertical rod part 7d hanging from the tip thereof and shorter than the first vertical rod part 7b, and the horizontal rod part 7e bent from the lower end thereof. One end (horizontal rod portion 7a) of the support fitting 7, which is formed in a shape to bypass the upper part, is fixed to the tip of the large basin 3, and the other end (horizontal rod portion 7e) of the support fitting 7 is fixed to the drain groove. fixed to the formwork 6.

してもよい。 The drainage ditch formwork 6 is formed into a hollow shape as shown in FIGS. 1 and 2, and has grooves at both ends in the longitudinal direction.
A flange portion 11 having small holes 11a is formed. The other end of the support fitting 7 and the drainage ditch formwork 6 are fixed by the horizontal rod portion 7e of the support fitting 7.
The projections 12 erected on the side surfaces of the small holes 11a
This is done by inserting... Although not shown, both 6 and 7 may be fixed with bolts, nuts, etc.
この状態で、下面用型枠１上にコンクリートを

５ａ、支持具５ｂを省略することが可能である。 As shown in the figure, by installing the support fitting 7 with its first vertical rod portion 7b in contact with the formwork 2 for the side surface of the nose, the support fitting 7 can also be used as a support for the formwork 2. That will happen. In addition, in the illustrated embodiment, the formwork 6 for the drainage ditch is also supported by the spacer 5c, but if the rigidity of the support fitting 7 is sufficiently high, the spacer 5c, the bracket 5a, and the support 5b may be omitted. It is possible to do so.
本考案は、上述の構成よりなるため、排水溝用
型枠の組立及び脱型を、下面用型枠の上方からの
作業のみによつて容易かつ迅速に行うことができ
る。 Since the present invention has the above-described configuration, it is possible to easily and quickly assemble and demold the drain formwork only by working from above the bottom formwork.
また、下面用型枠を貫通するセパレーターや木
製コーンを使用しないため、排水溝用型枠とし
て、実施例のような中空形状のものを使用でき
る。従つて、コンクリートの打設時に、コンクリ
ートの一部が排水溝用型枠に流れ込んで硬化し、
脱型が困難になるという不都合を回避できる。 Furthermore, since no separator or wooden cone is used to penetrate the bottom formwork, a hollow form like the one in the embodiment can be used as the drain gutter formwork. Therefore, when concrete is poured, some of the concrete flows into the drain formwork and hardens.
This avoids the inconvenience of difficulty in demolding.
