建物の建築工事や地下構造物の構築工事或いはそれに伴う山留め、根切りなど の土工事や基礎工事などにおいては、工事敷地の地上１階部分に作業用構台が仮 設され、この構台を利用することにより、鋼材、コンクリートなどの資材搬入或 いは掘削土砂などの運搬用ダンプカーやクレーンなどの建設重機を工事敷地内に 乗入れ可能なようにして、地下階（場合によっては地上階）の躯体工事が行われ ている。 For construction work of buildings, construction of underground structures, and accompanying earth works such as earth retaining and root cutting, and foundation works, a work gantry is temporarily installed on the first floor above the construction site, and this gantry is used. By doing so, it becomes possible to carry in materials such as steel and concrete or construction heavy equipment such as dump trucks and cranes for transporting excavated earth and sand on the construction site, and construct the basement (ground floor in some cases) Is being done.
【０００３】 従来の構台は、図１２〜１４に例示するように、地中に打ち込んだ複数の支柱 １と、その支柱上に設ける複数の主桁２と、この各主桁の上側に所定の間隔をも って横架される副桁３と、前記各桁（以下これらを構台桁と称する）２、３の上 側に連続して多数枚連続して載置される鋼製の矩形状覆工板４とによって、地上 よりも高所に平坦作業面５が構成されている。そして、出入口となる道路側から の乗入れ位置と、前記平坦作業面５とを接続するように乗入れスロープ６が設け られている。As shown in FIGS. 12 to 14, the conventional gantry has a plurality of pillars 1 driven into the ground, a plurality of main girders 2 provided on the pillars, and a predetermined number of columns above the main girders. Sub girders 3 that are laterally laid at intervals and steel rectangular shapes that are continuously placed on the upper side of each girder (hereinafter referred to as gantry girders) 2 and 3 A flat work surface 5 is formed above the ground by the lining plate 4. A boarding slope 6 is provided so as to connect the boarding position from the side of the road serving as the doorway and the flat work surface 5.
【０００４】 ところで上記の建設・土木工事は大方が屋外で行われ、かつ工期が長期に及ぶ ために、降雨などの悪天候に遭遇し、雨水が掘削工事現場内に流入することが避 けられない。その場合において、多量の雨水で工事現場内を水浸しにすることが あり、土がぬかって掘削途中で作業を中断せざるを得ないことがある。降水量が 大きいときには、排水ポンプを設置し、排水作業に時間を割かねばならず余計な 費用が必要となることがある。また、工事敷地内に構台が仮設されていても、構 台作業面を形成する覆工板はすき間無く敷設されておらず、覆工板間には多少の 空隙が形成されているのが常である。そのうえ重車両の荷重などにより、覆工板 自体が撓んだり、ずれ動いて、隣合う覆工板間にすき間を生ずることを免れない 。そのため降雨時、構台の上に降った雨水は、多数の覆工板のすき間から掘削工 事現場内に流入する。By the way, since most of the above-mentioned construction and civil engineering work is performed outdoors and the construction period is long, it is inevitable that rainwater will flow into the excavation work site due to encountering bad weather such as rainfall. . In that case, a large amount of rainwater may flood the inside of the construction site, and the soil may be wiped out and the work may have to be interrupted during excavation. When the amount of precipitation is high, it may be necessary to install drainage pumps and spend time for drainage work, resulting in extra costs. Even if a gantry is temporarily installed on the construction site, the lining plate forming the work surface of the gantry is not laid without a gap, and there are usually some gaps between the lining plates. Is. In addition, the load of heavy vehicles will inevitably cause the lining plate itself to bend or move, creating a gap between adjacent lining plates. Therefore, when it rains, the rainwater that falls on the gantry flows into the excavation work site through the gaps in the many lining plates.
【０００５】 一般にかかる構台の設置面積は、建築工事敷地全体の約２〜４割を占める。 因みに、降雨量１ミリの雨でも２５メートルと１２メートルの水泳プールに降れ ば３００リットルで普通のドラム缶にして１本半である。１日あたり２０ミリの 雨が降ったとすると、その量はドラム缶に換算し３０本分となる。従ってその量 の雨水が覆工板のすき間から漏れると、鉄筋溶接作業、鉄筋圧接作業、ガス加工 、曲げ加工等の作業場を構台下（覆工板の下）に確保ができず、あるいは作業能 率、作業安全性が低下するので作業日程が延びる一因となっている。Generally, the installation area of such a gantry occupies about 20 to 40% of the entire construction site. By the way, even if it rains 1 mm, if it falls in a swimming pool of 25 meters or 12 meters, it will be 300 liters, which is one and a half as an ordinary drum can. If 20 mm of rain falls a day, the amount will be 30 drum equivalents. Therefore, if that amount of rainwater leaks from the gap of the lining plate, it is not possible to secure a work space under the gantry (under the lining plate) for work such as rebar welding work, rebar pressure welding work, gas processing, and bending work. This lowers the efficiency and work safety, which is one of the reasons for extending the work schedule.
【０００６】[0006]
昨今、現場作業が悪天候による影響を極力受けないようにするために、建設現 場を仮設テントあるいはドーム方式の仮設屋根で覆う手段が開発され、その一部 は既に実用に供されている。ところが、上記構台の直上部までもテントなどの仮 設屋根で覆うことは、その架設設備が大がかりとなり、手間がかかりすぎ費用が 高くつく上に、クレーンなどによる資材の揚重作業の際に、テントなど仮設屋根 が邪魔になり、かえって作業の効率化を妨げる結果となる。従って、構台の上空 は仮設屋根で覆うことなく解放（露出）状態にせざるを得ない。 Recently, in order to prevent the site work from being affected by bad weather as much as possible, a means of covering the construction site with a temporary tent or a dome-type temporary roof has been developed, and part of it has already been put to practical use. However, covering even the upper part of the above gantry with a temporary roof such as a tent requires a large amount of erection equipment, is too time-consuming and expensive, and also when hoisting materials with a crane, etc. Temporary roofs such as tents get in the way, which hinders work efficiency. Therefore, the sky above the gantry must be left open (exposed) without being covered by the temporary roof.
【０００７】 本考案の目的は上記問題点に鑑み、降雨時に雨漏りせず、掘削工事現場内に雨 水が流入するのを防止できる構台及び工事現場全体を雨水から保護し、雨天によ る影響を大幅に低減させて施工を全天候化し得る建築工事現場の遮水システムを 提案することにある。In view of the above problems, an object of the present invention is to prevent rainwater from leaking into the excavation work site during rain, protect the gantry and the entire construction site from rainwater, and protect them from rain. The purpose of this is to propose a water-blocking system at a construction site that can significantly reduce construction and weather the construction.

FIG. 7 shows an example in which the water collecting trough 11R is attached to the lower side of the girder 3R.
【００１８】 なお図４、５において符号１４で示すものは、構台の作業面先端に取り付けた 堰の機能を有する水返し（金物）である。この水返し１４により雨水が構台先端 から掘削現場内に流下しないよう構成されている。作業面には適当な水勾配を形 成させることもできる。符号１５は保安柵を示す。In FIG. 4 and FIG. 5, reference numeral 14 is a water sink (metal) having the function of a weir attached to the tip of the work surface of the gantry. This water return 14 prevents rainwater from flowing down from the tip of the gantry into the excavation site. A suitable water gradient can be created on the work surface. Reference numeral 15 indicates a security fence.
【００１９】 次に本考案の変形例について説明する。図８に示した実施例は、相隣りあう覆 工板４の四周の連接面に、ゴム、プラスチック等からなる弾性材料製シール片１ ６を取り付けて、シール片相互を圧接させて覆工板相互の連接面を水密に接続し た事例である。Next, a modified example of the present invention will be described. In the embodiment shown in FIG. 8, sealing pieces 16 made of an elastic material made of rubber, plastic, or the like are attached to the connecting surfaces of four adjacent covering plates 4 made of rubber, plastic, and the sealing pieces are pressed against each other to make a covering sheet. This is a case where the connecting surfaces are connected in a watertight manner.
【００２０】 上記実施例では覆工板の連接面にシール片の取付溝１７を形成して、当該溝に シール片１６を装着する。なお、覆工板４の連接部に貼り付けた弾性材料製シー ル片１８の一方と、相隣りあう覆工板４の連接面（垂直面）とを直接圧接させて 覆工板相互の連接部を水密的に接続させることも可能である（図９参照）。図８ 、図９の何れの場合にしても、相隣りあう覆工板の連接面に取り付けたシール片 の作用で、覆工板のすき間からの水漏れが防止できるものである。In the above embodiment, the mounting groove 17 of the seal piece is formed on the connecting surface of the lining plate, and the seal piece 16 is mounted in the groove. Note that one of the elastic material seal pieces 18 attached to the connecting portion of the lining plate 4 and the connecting surface (vertical surface) of the adjacent lining plate 4 are directly brought into pressure contact to connect the lining plates to each other. It is also possible to connect the parts in a watertight manner (see FIG. 9). In either case of FIG. 8 and FIG. 9, water leakage from the gap of the lining plate can be prevented by the action of the seal piece attached to the connecting surface of the adjacent lining plates.
【００２１】 また、建築工事現場全体を降雨から保護するために、本考案の構台の直上部以 外の空間、すなわち構台上空を除く建築しようとする予定構造物の外周部に、足 場や昇降ポスト、支柱その他の支持体を組み立て、その上に建築工事用仮設テン ト２１を取り外し自在に設置することができる。その場合、図１０に示すように 該構台２０の作業面端部の上に、建築しようとする予定構造物を収容する空間を 形成する仮設テント２１の支柱を支持する支持体２２を取り付ける。Further, in order to protect the entire construction site from rain, a scaffold or a lift is provided on a space other than directly above the gantry of the present invention, that is, on the outer periphery of the structure to be constructed excluding the sky above the gantry. It is possible to assemble a support such as a post, a column, and the like, and to dismount the temporary construction building tentent 21 thereon. In that case, as shown in FIG. 10, a support 22 for supporting the columns of the temporary tent 21 forming a space for accommodating the planned structure to be built is attached on the end of the work surface of the gantry 20.
【００２２】 上記実施例によれば、降雨時、仮設テント側から流下した雨水は構台の上に流 れるようにすると構台２０の上に流下した雨水は、水密に接続された覆工板から 構台桁上部に設けた集水樋に流下し、覆工板のすき間から構台の下に雨漏りする 事が防止できる。従って、構台２０と仮設テント２１を併用することにより工事 現場全体を雨水から保護し、雨天による影響を大幅に低減させて施工を全天候化 し得る。According to the above-described embodiment, when it rains, the rainwater that flows down from the temporary tent side is allowed to flow over the gantry, and the rainwater that flows down over the gantry 20 flows from the lining plate connected in a watertight manner to the gantry. It is possible to prevent rain from leaking under the gantry from the gap in the lining plate by flowing it down to the water collecting gutter provided at the upper part of the girder. Therefore, by using the gantry 20 and the temporary tent 21 together, the construction site as a whole can be protected from rainwater, and the influence of rainy weather can be greatly reduced and the construction can be weathered.
【００２３】 以下図１１を参照して仮設テント２１の構造を簡単に説明すると、図において 符号２３は山形した屋根部材、２４は前記屋根部材の両端に固定をした支柱部材 である。これら部材は仮設テントの骨組みとなるもので、いずれもアルミ軽量構 造材を使用して形成することを可とする。前記両部材からなる単位のフレームを 複数本並設して、その相対するフレームに母屋及び／またはブレースを渡して小 屋組した屋根ユニットの屋根面を可撓性シート材２５で覆設して仮設テント２１ を形成させる。こうして組み立てた仮設テントを前記の支持体の上にクレーンな どにより取り外し可能に設置する。The structure of the temporary tent 21 will be briefly described below with reference to FIG. 11. In the figure, reference numeral 23 is a mountain-shaped roof member, and 24 is a column member fixed to both ends of the roof member. These members form the framework of the temporary tent, and all of them can be made of lightweight aluminum structural materials. A plurality of unit frames composed of both members are arranged side by side, and a purlin and / or brace is passed to the opposing frames to cover the roof surface of a roof unit with a flexible sheet material 25. A temporary tent 21 is formed. The temporary tent assembled in this way is removably installed on the support by a crane or the like.
