Description

【０００１】
【発明の属する技術分野】
本発明は、橋梁工事、各種建築工事、あるいは土木工事等において、所要の橋桁や大トラス等の重量物を架設せしめるさいに使用する折畳み自在な支保工に関する。
【０００２】
【従来の技術】
従来より、この種の折畳み自在とされた支保工としては、本発明者が先に提案した支保工、即ち、両側一対の支柱を筋かいや水平つなぎ材等により連結して方形状に形成された少なくとも両側一対の支保枠部材が所定間隔をおいて配設され、該各両側の支保枠部材上には順次同形状とされた所要数の支保枠部材がヒンジ部材を介して折畳み自在に連結され、両側に各々相隣る支保枠部材の両側は所要長の間隔規制部材を介して折畳み方向に回動自在に連結されると共に筋かいが後付け自在とされ、かつ、両側に相隣る支保枠部材間には水平つなぎ材等を介して階段や床付き布わく等所要の支保工部材が折畳み方向に回動自在に組付けられたものが知られている（特開２００２−２１２９２０号公報参照）（特許文献１）。
そして、上述の如く構成された従来の支保工は、最上部の両側支保枠部材をクレ−ン等により吊上げつつ、順次ヒンジ部材を介して両側の支保枠部材を間隔規制部材により間隔規制せしめつつ起立せしめると共に、これに連動して階段や床付き布わく等の支保工部材を回動せしめつつ起立せしめたのち、相隣る支保枠部材の両側を筋かいにより交差状に連結して組立てる。
逆に、折畳むさいには、最上部の両側支保枠部材をクレ−ン等により吊下げつつ、最下部の両側支保枠部材より順次後付け筋かいを取外しつつヒンジ部材を介して順次折重ねると共に、これに連動して階段や床付き布わく等の支保工部材を回動せしめつつ両側支保枠部材間に折込み、全体をコンパクトに折畳むものである。
【０００３】
【発明が解決しようとする課題】
ところで、上述の如く構成された従来の支保工は、その組立て時においては床付き布わく等の支保工部材と水平つなぎ材・間隔規制部材との間に隙間を生じるため、物品の落下防止や作業者の安全確保等の点から幅木を囲繞状に取付けて塞ぐものとされている。そして、かかる幅木の取付けは、両側一対の支保枠部材間に組付けた階段や床付き布わく等が邪魔となって囲繞状に組付けることが非常に困難であることから、従来より組立て後に後付けするものとされており、ひいては、その作業が非常に面倒で手間がかかるのみならず、折畳み時には逆に一々取外さなければならないものであって、全体として支保工の組立て・折畳み作業能率を低下せしめるものとなっていた。
また、支保工の組立て時において取付ける親綱支柱においても、支保工自体が折畳み自在とされているから、必然的に後付けせざるを得ず、ひいては、その取付け作業が非常に面倒で手間がかかるのみならず、折畳み時には逆に一々取外さなければならず、全体として支保工の組立て・折畳み作業能率を低下せしめるものとなっていた。

BACKGROUND OF THE INVENTION
The present invention relates to a foldable support for use in laying a heavy object such as a required bridge girder or a large truss in bridge construction, various construction work, or civil engineering work.
[0002]
[Prior art]
Conventionally, as this type of foldable support, the support previously proposed by the present inventor, i.e., a pair of struts on both sides connected by a brace or horizontal connecting material, etc., is formed into a square shape. Further, at least a pair of supporting frame members on both sides are arranged at a predetermined interval, and a required number of supporting frame members having the same shape are sequentially connected to the supporting frame members on both sides so as to be foldable via hinge members. The support frame members adjacent to each other on both sides are connected to each other in a folding direction via a required length regulating member, and the brace can be retrofitted. It is known that a required supporting member such as a staircase or a cloth with a floor is assembled between the frame members so as to be rotatable in a folding direction via a horizontal connecting material (Japanese Patent Laid-Open No. 2002-221920). (See Patent Document 1).
In the conventional support constructed as described above, the uppermost support frame members are lifted by a crane or the like, and the support frame members on both sides are sequentially regulated by the distance regulation member via the hinge members. In addition to standing up, the support members such as the staircase and the cloth with the floor are turned up in conjunction with this, and then the both sides of the adjacent support frame members are connected to each other in a crossing manner by a brace.
Conversely, when folding, the uppermost support frame members are suspended by a crane, etc., and the rear support brace members are sequentially removed from the lowermost support frame members while being folded sequentially via hinge members. In conjunction with this, the support members such as the staircase and the cloth with the floor are rotated while being folded between the two support frame members, and the whole is folded compactly.
[0003]
[Problems to be solved by the invention]
By the way, the conventional support constructed as described above has a gap between the support member such as cloth with a floor and the horizontal connecting material / spacing regulating member at the time of assembly. From the standpoint of ensuring the safety of workers, the skirting board is attached and closed in a go shape. And it is very difficult to assemble the skirting board because it is very difficult to assemble it in the shape of a fence because the staircase and the cloth with the floor assembled between the pair of support frame members on both sides are obstructive. It is supposed to be retrofitted later, and as a result, the work is not only very cumbersome and time-consuming, but also must be removed one by one when folding, and the assembly and folding work efficiency of the support work as a whole It was a thing that lowered.
In addition, the support struts that are attached during the assembly of the support are also foldable, so they must be retrofitted, and the installation work is very cumbersome and time-consuming. In addition, when folding, it must be removed one by one, which reduces the assembly and folding work efficiency of the support as a whole.

According to the second aspect of the present invention, a storage tube having a required length is attached to the outermost support frame member constituting the support work, and a master strut is attached to the storage tube via a latch pin. Since the main support column is pulled out from the storage tube to stand up to the required length when assembling the support, it is stored in the storage tube and folded along the support frame member after use. As compared with the conventional example in which the master rope support is retrofitted, the assembling / folding work efficiency of the support work can be remarkably improved.
