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。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable shoring for use in erection of a heavy object such as a required bridge girder or large truss in bridge construction, various construction works, or civil engineering work.
[0002]
[Prior art]
Conventionally, as this type of shoring that is made freely foldable, a shoring proposed by the inventor of the present invention, that is, a pair of struts on both sides is connected to each other by a bracing or a horizontal connecting material to form a square shape. At least a pair of support frame members on both sides are arranged at a predetermined interval, and a required number of support frame members having the same shape are sequentially connected to the support frame members on each side via hinge members so as to be foldable. Both sides of the supporting frame members adjacent to each other on both sides are connected rotatably in the folding direction via a spacing regulating member of a required length, and a brace is made freely attachable. It is known that necessary supporting members such as stairs and floor-attached fabrics are rotatably mounted in a folding direction between frame members via a horizontal connecting member (Japanese Patent Application Laid-Open No. 2002-212920). (Patent Document 1).
In the conventional shoring constructed as described above, the uppermost both-side support frame members are lifted by a crane or the like, and the both-side support frame members are successively regulated by the gap regulating members via the hinge members. After the support members such as stairs and floor-attached fabric are rotated and erected in conjunction with this, the adjacent support frame members are assembled by connecting both sides of the adjacent support frame members in a crossed manner with braces.
Conversely, for folding, the uppermost both-side support frame members are hung by a crane or the like, and the lower-side both-side support frame members are sequentially folded via the hinge members while removing the retrofitting braces from the lowermost both-side support frame members. In conjunction with this, the supporting members such as stairs and floor-attached fabric are rotated and folded between the supporting frame members on both sides, whereby the whole is compactly folded.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional shoring constructed as described above, at the time of assembling, a gap is generated between a shoring member such as a floor-attached fabric and a horizontal tie member / spacing regulating member. From the viewpoint of ensuring the safety of workers, etc., the baseboard is attached and closed in a surrounding shape. The mounting of the baseboard is difficult because the steps and the fabric with the floor mounted between the pair of support frame members on both sides are very difficult to mount in a surrounding shape. It is supposed to be retrofitted later, and the work is not only troublesome and time-consuming, but also has to be removed one by one when folding, and as a whole the assembling and folding work efficiency of the shoring work Was reduced.
Also, in the main rope support to be attached at the time of assembling the supporter, the supporter itself is foldable, so it is inevitably attached later, and the installation work is extremely troublesome and troublesome. Not only that, it must be removed one by one at the time of folding, which reduces the efficiency of assembling and folding work of the shoring as a whole.
[0004]
