【０００１】0001
本考案は建築物等の構築時においてコンクリート床に設けられる床開口の仮設 蓋装置に係るものである。 This invention is a temporary construction for floor openings provided in concrete floors during the construction of buildings, etc. This relates to a lid device.
【０００２】0002
従来、建築物等を構築する場合、二重床内の後工事をするため、コンクリート 打設時に所要の大きさの型枠を配設して、二重床内に作業員が出入できるように 開口部を施工していた。 同開口部は工事中の作業員、施工機器の落下の危険のないように、木製または 鉄製の仮設蓋を設け、取外し自在に養生するように設置している。 Traditionally, when constructing buildings, etc., concrete was used for post-construction work inside the double floor. During pouring, formwork of the required size is placed to allow workers to enter and exit the double floor. An opening was being constructed. The opening should be made of wood or A temporary iron cover has been installed and is installed so that it can be removed and used for curing.
【０００３】0003
前記従来方法による床開口部の養生は、二重床内の作業を行なう場合、前記木 製、あるいは鉄製の蓋を一旦取り外してその近傍に置き、作業が終了すると元の 位置に戻しているが、蓋の重量が可成りあり、元の位置に戻すことが面倒であっ たり、復旧を忘れて現場を立ち去ることもしばしばあり、作業員の落下や資材の 転倒等の事故が起きることがあった。 Curing of floor openings using the conventional method is recommended when working inside a double floor. Remove the wooden or iron lid and place it near it, and when the work is finished, replace it with the original one. I returned it to its original position, but the lid is quite heavy and it is a pain to return it to its original position. They often forget to carry out repairs and leave the site, resulting in workers falling and materials being lost. Accidents such as falls may occur.
【０００４】 本考案は前記従来技術の有する問題点に鑑みて提案されたもので、その目的と する処は、床開口部における作業員の転落や資材の落下事故が防止され、取り扱 いが簡単で確実に架設できる床開口部の仮設蓋装置を提供する点にある。0004 The present invention was proposed in view of the problems of the above-mentioned prior art, and its purpose is Places where workers are exposed to floor openings and materials are prevented from falling and materials are not handled properly. To provide a temporary cover device for a floor opening that can be easily and reliably erected.

前記の目的を達成するため、本考案に係る床開口部の仮設装置は、床開口部の 周縁に嵌装された方形枠の一側枠片に前記開口部の仮設蓋の一側縁を蝶着し、同 仮設蓋の自由端部近傍の裏面と前記方形枠における仮設蓋が蝶着された一側枠片 と対向する他側枠片とに亘って安全ネツトを張設し、前記開閉蓋に開閉蓋の支持 用支柱の一端を起伏自在に枢支して構成されている。 In order to achieve the above object, the temporary device for floor openings according to the present invention One side edge of the temporary lid of the opening is hinged to one side frame piece of the rectangular frame fitted around the periphery, and one side frame piece to which the temporary lid is hinged to the back surface near the free end of the temporary lid and the square frame; A safety net is stretched across the opposite side frame piece, and a safety net is provided to support the opening/closing lid on the opening/closing lid. It is constructed by pivoting one end of the support column so that it can rise and fall freely.
【０００６】[0006]
本考案は前記したように構成されているので、床開口部を開放する場合、同開 口部の周縁に嵌装された方形枠の一側片に蝶着された仮設蓋を回動して前記開口 部を開放すると、同仮設蓋が一定の角度にまで開蓋されると、同仮設蓋に一端を 枢支された支柱が同蓋より垂下して前記開口部周縁の床上に同蓋を支持すること によって、前記仮設蓋を前記開口部の開放位置に保持する。 Since the present invention is configured as described above, when opening the floor opening, it is necessary to open the floor opening. The opening is closed by rotating a temporary lid hinged to one side of a rectangular frame fitted around the periphery of the opening. When the temporary cover is opened to a certain angle, one end is attached to the temporary cover. A pivotably supported post hangs down from the lid to support the lid on the floor around the opening. to hold the temporary lid in the open position of the opening.
【０００７】 而して作業員が床開口部内の作業を行なう場合、前記仮設蓋と前記方形枠にお ける仮設蓋が蝶着された一側枠片との間に張設された安全ネツトを外して床下に 入り、安全ネツトを復旧して作業を行なう。 かくして仮設蓋の開蓋中、同蓋と安全ネツトとによって開口部の所在が確認さ れるとともに、安全ネツトによって作業員の転落、機材の落下が防止され、作業 が安全に行なわれる。[0007] Therefore, when workers work inside the floor opening, the temporary cover and the square frame must be Remove the safety net stretched between the hinged temporary lid and the one side frame piece, and place it under the floor. Enter, restore the safety net, and carry out the work. Thus, while the temporary cover is being opened, the location of the opening can be confirmed by the temporary cover and the safety net. At the same time, the safety net prevents workers from falling and equipment from falling, making work easier. is carried out safely.
【０００８】 作業終了時は、前記支柱を折畳んで仮設蓋の支持を解除し、同蓋を前記方形枠 の一側片に対して回動して、開口部を閉塞するものである。[0008] When the work is finished, fold the support column to release the support from the temporary lid, and attach the lid to the rectangular frame. The opening is closed by rotating relative to one side of the opening.
【０００９】[0009]
以下本考案を図示の実施例について説明すると、１は建築物を構築する際にコ ンクリート床２に設けた開口部で、同開口部１の周縁には方形枠３が嵌装されて いる。同方形枠３の一側枠片３a には仮設蓋４の一側縁が開閉自在に蝶番５を介 して取付けられ、同蓋４の自由端縁近傍と、前記方形枠３における仮設蓋４が蝶 着された一側枠片３a と対向する他側枠片３b との間に亘って安全ネツト６が張 設されている。更に前記仮設蓋４の表面に仮設蓋４の支持用支柱７が枢着部８を 介して起伏自在に取付けられている。 The present invention will be explained below with reference to the illustrated embodiments. An opening provided in a concrete floor 2, with a rectangular frame 3 fitted around the periphery of the opening 1. There is. One side edge of the temporary lid 4 is attached to one side frame piece 3a of the isogonal frame 3 via a hinge 5 so that it can be opened and closed freely. The temporary lid 4 near the free edge of the lid 4 and the square frame 3 are attached with a hinge. A safety net 6 is stretched between the attached frame piece 3a on one side and the opposing frame piece 3b on the other side. It is set up. Furthermore, the support strut 7 of the temporary lid 4 has a pivot portion 8 on the surface of the temporary lid 4. It is attached so that it can be raised and lowered freely.
【００１０】 図示の実施例は前記したように構成されているので、仮設蓋４を図１における 点線に示すように開口部１を所定角度まで開放すると、前記支柱６が垂下してコ ンクリート床２上に仮設蓋４を開蓋位置に保持する。 而して作業員が床開口部１内の作業をするときは安全ネツト６を外して床下に 入り、安全ネツト６を復旧して所要の作業を行なう。0010 Since the illustrated embodiment is constructed as described above, the temporary lid 4 is When the opening 1 is opened to a predetermined angle as shown by the dotted line, the pillar 6 hangs down and the pillar 6 hangs down. The temporary lid 4 is held in the open position on the concrete floor 2. Therefore, when workers work inside the floor opening 1, they must remove the safety net 6 and place it under the floor. The operator enters the network, restores the safety net 6, and performs the necessary work.
【００１１】 かくして前記開口部１の開放中でも、起立状態にある仮設蓋４と安全ネツト６ とによって同開口部１の所在が明らかにされ、他の作業のための歩行、資材の運 搬が安全に行なわれ、安全ネツト６によって作業員や資材の転落が防止される。 図３乃至図５は本考案の他の実施例を示し、仮設蓋４の裏面に内蔵された下端 面が開口した箱体９に、支柱７の端部に装着された筒状片１０の先端２叉状片１ ０a が枢着１１され、同筒状片１０より突設されたピン１２が前記筒状片１０に 穿設された円弧状溝１３に可摺動的に嵌合し、前記支柱７が前記箱体４に対する 枢着１１部を中心とし、ピン１２と円弧状溝１３とを案内として回動し、前記仮 設蓋４を開蓋位置に保持するように構成されている。[0011] Thus, even when the opening 1 is open, the temporary lid 4 and the safety net 6 remain in the upright position. The location of the opening 1 is clarified by Transport is carried out safely, and the safety net 6 prevents workers and materials from falling. 3 to 5 show other embodiments of the present invention, in which the lower end is built into the back of the temporary lid 4. A cylindrical piece 10 attached to the end of a support 7 is attached to a box body 9 with an open surface, and a pronged piece 1 is attached to the tip of the cylindrical piece 10. 0a is pivotally mounted 11, and a pin 12 protruding from the cylindrical piece 10 is attached to the cylindrical piece 10. The pillars 7 are slidably fitted into the drilled arcuate grooves 13, and the pillars 7 are It rotates around the pivot 11 using the pin 12 and the arcuate groove 13 as guides, and the temporary The lid 4 is configured to be held in the open position.
【００１２】 なお前記支柱７の先端には伸縮柱１４が可摺動的に嵌装されるとともに、とめ ねじ１５で支柱７に固定されるようになっていて、仮設蓋４の角度を調整できる ようになっている。0012 In addition, a telescopic column 14 is slidably fitted to the tip of the column 7, and a stopper is provided. It is fixed to the support column 7 with screws 15, and the angle of the temporary lid 4 can be adjusted. It looks like this.
【００１３】[0013]
本考案によれば前記したように、床開口部の周縁に嵌装された方形枠の一側枠 片に、仮設蓋の一側縁が蝶着され、同仮設蓋の自由端部近傍と前記方形枠におけ る仮設蓋が蝶着された一側枠片と対向する他側枠片とに亘って安全ネツトが張設 されているので、前記開口部は常時は仮設蓋で閉蓋されており、二重床内の作業 をするときは同蓋を開放して作業員が二重床内に入り、安全ネツトを張り直し、 作業終了後、仮設蓋を元に復旧することにより、簡単な作業で作業員の転落や資 材の落下等の事故を防止しうるものである。 According to the present invention, as described above, one side frame of the rectangular frame is fitted around the periphery of the floor opening. One side edge of the temporary lid is hinged to the piece, and the area near the free end of the temporary lid and in the square frame is A safety net is stretched across the frame piece on one side to which the temporary lid is hinged and the opposing frame piece on the other side. Therefore, the opening is always closed with a temporary lid, and work inside the double floor is prohibited. When doing so, the worker opens the lid, enters the double floor, reinstalls the safety net, and After the work is completed, the temporary lid can be restored to its original position, making it easy to prevent workers from falling and preventing equipment from falling. This can prevent accidents such as falling materials.
