この考案はスラブ型枠と梁型枠とを一体構成し
た上下階の大型型枠間に上下階に通じる仮設階段
を設けた階段付き大型型枠に関する。[Detailed Description of the Invention] This invention relates to a large formwork with stairs that is constructed by integrally constructing a slab formwork and a beam formwork, and in which a temporary staircase leading to the upper and lower floors is provided between the large formworks for the upper and lower floors.
鉄筋コンクリート構造物の型枠工事において、
鉄筋の組立、型枠の組立・解体並びにコンクリー
トの打設等の作業を行なうために上下階の型枠間
には作業員が上下階を往き来するはしごや仮設の
階段が取付けられている。 In formwork work for reinforced concrete structures,
In order to perform work such as assembling reinforcing bars, assembling and dismantling formwork, and pouring concrete, ladders and temporary stairs are installed between the formwork on the upper and lower floors for workers to go back and forth between the upper and lower floors.
しかし、この種のはしごや仮設階段は工事の進
行に並行してその組立・解体作業が何回となく繰
り返されるため構造が簡単でかつ組立・解体作業
が迅速にできることが必要である。 However, this type of ladder or temporary staircase must have a simple structure and be able to be assembled and dismantled quickly because the assembly and disassembly operations are repeated many times as construction progresses.
この考案は前記事情を鑑み考案されたものでそ
の目的は構造が簡単でかつ組立・解体が迅速にで
きる階段を組み込んだ大型型枠を提供することに
ある。 This invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a large formwork incorporating stairs that has a simple structure and can be quickly assembled and dismantled.
以下、この考案を図示する一実施例によつて説
明する。 This invention will be explained below with reference to an illustrative embodiment.
第１図ａ，ｂ，ｃは大型型枠を示し、大型型枠
１はスラブ型２と梁型枠３を繋ぎ材４によつて連
結することによりスラブ型枠２と梁型枠３を一体
構成したものである。 Figure 1 a, b, and c show large formworks, and the large formwork 1 integrates the slab formwork 2 and beam formwork 3 by connecting the slab formwork 2 and beam formwork 3 with a connecting material 4. It is composed of
スラブ型枠２は合板と根太とからなる堰板を軽
量形鋼等を上下弦材としかつ鉄筋等を斜材として
なる複数本のトラス梁５，……の上に固定したも
のである。 The slab formwork 2 is a weir plate made of plywood and joists fixed onto a plurality of truss beams 5, .
第２図および第３図に示すように、パイプシヤ
フト，エレベーターシヤフトまたは吹抜けを形成
する目的でスラブ型枠２に設けた開口部６には上
下階に通ずるように仮設階段７が取付けられてい
る。 As shown in FIGS. 2 and 3, a temporary staircase 7 is attached to an opening 6 provided in the slab formwork 2 for the purpose of forming a pipe shaft, elevator shaft, or atrium so as to lead to the upper and lower floors. .
階段７は上階段部分８と下階段部分９とから構
成されている。 The staircase 7 is composed of an upper staircase section 8 and a lower staircase section 9.
上階段部分８はスラブ型枠２の繋ぎ材４，４間
に固定されている。また、上階段部分８の上端部
には開口部６内に嵌り込む相当大の作業足場１０
が取付けられ、作業足場１０はトラス梁５，５間
に固定されている。 The upper staircase part 8 is fixed between the connecting members 4, 4 of the slab formwork 2. Further, at the upper end of the upper staircase portion 8, a fairly large work scaffold 10 that fits into the opening 6 is provided.
is attached, and the work scaffold 10 is fixed between the truss beams 5, 5.
下階段部分９はその上端部に形成された掛止部
１１を受け梁１２に引つ掛けて受け梁１２と下階
の床間に掛けわたされている。また、下階段部分
９は取付け・取外しが自由になつている。符号１
３は下階段部分９を受ける受け板であり、受け板
１３には下階段部分９の滑りを防止するために止
め木１４が取付けられている。 The lower stair portion 9 is hooked onto the receiving beam 12 by a hooking portion 11 formed at its upper end, and is extended between the receiving beam 12 and the floor of the lower floor. Further, the lower staircase portion 9 can be freely attached and removed. code 1
3 is a receiving plate for receiving the lower stair portion 9, and a stopper 14 is attached to the receiving plate 13 to prevent the lower stair portion 9 from slipping.
このような構成において、型枠の組立て時には
大型型枠１の組立てと同時に階段７の上階段部分
８が構成されてしまうため受け梁１２と下階の受
け板１３に下階段部分９を掛けわたすだけで階段
７の使用は可能になる。 In such a configuration, when assembling the formwork, the upper stair portion 8 of the staircase 7 is constructed at the same time as the large formwork 1 is assembled, so the lower stair portion 9 is spanned over the support beam 12 and the support plate 13 on the lower floor. Stairs 7 can now be used.
一方、型枠の解体時には第４図および第５図に
示すように大型型枠１を下階の床に降すと同時に
上階段部分８が階段の下階段部分になりかつ作業
足場１０が階段の踊り場になるため作業足場１０
と上階床間に下階段部分９を掛けわたすだけで階
段７の使用は可能になる。 On the other hand, when the formwork is dismantled, the large formwork 1 is lowered to the lower floor as shown in FIGS. Work scaffolding 10 to become a landing area
Stairs 7 can be used simply by extending the lower stair portion 9 between the upper and upper floors.
なお、階段７は大型型枠１とともに上階に盛替
え使用できることは言うまでもない。 Note that it goes without saying that the stairs 7 can be relocated to the upper floor together with the large formwork 1.
この考案は以上の構成からなり、次の効果が期
待できる。 This invention consists of the above-mentioned structure, and the following effects can be expected.
構造が簡単であるとともに組立・解体が迅速に
でき、延いては型枠工事の短縮化が可能である。
また、反復使用ができるため極めて経済的であ
る。 It has a simple structure and can be assembled and dismantled quickly, which in turn allows for shorter formwork work.
Moreover, it is extremely economical because it can be used repeatedly.
