本明細書ではこの鋼管製の足場について説明する。2. Description of the Related Art When constructing a building or the like, a working scaffold is temporarily provided around the building. Known types of scaffolds include those made of steel pipe, wood, and bamboo. Among them, a steel pipe scaffold is the most common, and therefore, this steel pipe scaffold will be described below in this specification.
【０００３】足場は、縦横方向に組み上げられる建枠
と、建枠間に架け渡されて作業通路を形成する踏板とを
有している。建枠は主としてパイプ材で形成されてお
り、踏板は格子状の凸部が表面に設けてあるシマ鋼板で
形成されている。[0003] The scaffold has a building frame assembled vertically and horizontally, and a tread spanned between the building frames to form a work passage. The building frame is mainly formed of a pipe material, and the tread is formed of a stiffened steel plate having a lattice-shaped convex portion provided on the surface.
【０００４】上記した足場を構成するこれらの建材は、

における踏板間に開口した隙間を形成してしまうことが
あった。なお、この隙間は足場の組法上、特に建造物の
角部近くに形成され易かった。[0004] These building materials constituting the scaffold described above are:
It is standardized by Japanese Industrial Standards (JIS) so that the size and strength do not vary depending on the manufacturer or the like. For this reason, depending on the shape of the building, the steel pipe scaffold cannot be tentatively installed around the building, and a gap opened between the treads on the scaffold may be formed. In addition, this gap was easily formed in the scaffolding method, especially near the corner of the building.

形成されている足場における踏板間に、更に踏板を載置
して架け渡すことで、この隙間を塞ぎ上記したような事
故の防止を図っている。[0005] If the gap is large, an accident such as an operator accidentally stepping on the foot or, in the worst case, falling down from the foot tends to occur, which is dangerous. Therefore, at the site, by further placing and bridging the treads between the treads on the scaffold having such gaps, the gaps are closed to prevent the above-described accident.

ために使用されるものである。そのため、当然ながら足
場における踏板間に形成された隙間を塞ぐような使用方
法は、設計段階において想定されておらず、従って、こ
の方法にあっては下記に示すような問題が生じている。As described above, a tread is originally used to form a temporary work floor by being bridged between building frames. Therefore, a method of use that closes the gap formed between the treads on the scaffold is naturally not assumed at the design stage, and therefore, the method has the following problems.

In addition, the work such as fixing the tread plate at this line has to be performed manually by each worker, which is troublesome and requires a lot of time. Furthermore, since the end of the line used for fixing the tread plate usually protrudes beyond the fastening portion, the end is bent in a required direction so as to prevent the walking worker from being injured. Or post-processing such as cutting.

この段差につまずくことがあり危険であった。Further, since the tread for closing the gap overlaps with the tread as the work temporary floor, the thickness of the tread is formed as a step on the work temporary floor, and the worker stumbles on the step. There was danger.

後加工も必要ない。In the scaffold member, the closing member can be fixed or substantially fixed to the scaffold by locking the locking means at a required position of a member such as a building frame. It is simple and hassle-free because there is no need to use such things. And it can be installed quickly. In addition, since the wire is not used, there is no need to perform post-processing of the wire to prevent injury.

が塞部材を通過することができるので、例えば、下方か
ら吹き上げ風を受けた場合でも、足場部材は、煽られて
浮き上がったりぐらついたりしにくく安全性が高い。In the case where the closing member is provided with the ventilation portion, the air can pass through the closing member. Therefore, for example, even when the scaffold member is blown up from below, the scaffold member may be lifted or wobble. It is hard to do and high safety.
【００２２】また、塞部材に通気部が設けられているも
のは、降雨の場合でも、雨水が塞部材上に溜りにくいた
め、溜り水による腐蝕や滑りを防止することができる。Further, in the case where the ventilation member is provided in the closing member, it is difficult for rainwater to collect on the closing member even in the case of rainfall, so that corrosion and slippage due to the accumulated water can be prevented.

を高めることができる。Since the scaffolding member only needs to be able to close the gap formed between the treads on the scaffold and prevent stepping out in cooperation with the strength of the treads, the high strength and high rigidity of the treads are not necessarily required. . Therefore, the closing member can be formed thinner than the tread plate to reduce the step with the tread plate. As a result, the worker is less likely to trip on a step and safety can be improved.

足場に固定または実質的に固定することができる。The hooking means includes a hook member and a movable claw member attached to the hook member via an engaging means so as to be movable between two engaging positions. When the movable claw member is at one of the engagement positions, the hook including the hook member is in an open state, so that the hook can be hooked to a member such as a building frame, and the other When in the mating position, the hook portion including the hook member is substantially closed, so that it is difficult for the hook member to come off from a member such as a building frame. This allows the closing member to be fixed or substantially fixed to the scaffold.

きる。従って、仮設作業床上でも持ち運びがし易い。Since the tread portion 10 is formed of a crimped wire net, it can be manufactured to be lighter than the tread plate. Moreover, since the scaffold member B is a dedicated member for closing the gap between the treads in the steel pipe scaffold, the size thereof can be considerably smaller than that of the treads, so that the weight can be further reduced. Therefore, it is easy to carry on a temporary work floor.

ことができる。The scaffold member B only needs to be able to close the gap formed between the treads in the steel pipe scaffold, and to prevent stepping out in cooperation with the strength of the tread. The high strength and high rigidity of the tread are not necessarily required. Therefore, the closing member 1 is formed thinner than the tread plate to reduce the level difference from the tread plate. As a result, the worker is less likely to trip on a step and safety can be improved.

材１を建枠に実質的に固定することができる。When the movable claw member 21 is at the engagement position of the engagement recess 231, the hook 2 including the hook member 20 is engaged.
Since 5 is in an open state, the hook member 20 can be hooked at a required position of the building frame. When the movable claw member 21 is moved to the engagement position of the engagement concave portion 232, the engaging portion 25 including the hook member 20 is substantially closed, that is, the lower side of the movable claw member 21 is engaged. Since the hook member 20 goes under the required position of the building frame, it is possible to prevent the hook member 20 from coming off from the building frame, whereby the closing member 1 can be substantially fixed to the building frame.
