トするようになつている。 The currently widely used frame scaffolding uses a gate-shaped building frame. That is, as shown in Fig. 1, a plurality of gate-shaped building frames 1 are arranged in parallel at predetermined intervals along the outer surface of a building, etc., and braces 2, 2 are placed between the adjacent ones. The horizontal land member 2 is placed at the top of the building frame after being stabilized in the horizontal direction.
Scaffolding board 3 is stretched between a and 2a, and this is the lowest level.A similar structural unit is installed on top of this by connecting the building frames 1 and 1, and this is repeated for the required level until the building frame of the highest level is installed. A post 4 is erected at 1, and a handrail 5 is set on this.

ところが、この種の足場は組立或いは解体作業
の途中において、各段の足場板３上に立つ作業者
に対し安全確保のための手摺がなく、甚だ危険な
作業を余儀なくされる問題がある。 However, this type of scaffolding has the problem that during assembly or disassembly work, workers standing on the scaffolding boards 3 at each stage are not provided with handrails to ensure their safety, forcing them to perform extremely dangerous work.

本考案の枠組足場はこの安全性の問題の解決を
図つたものであり、とくに建枠形状と筋違、手摺

する。 The frame scaffold of this invention is an attempt to solve this safety problem, and in particular, by adding innovations to the shape of the building frame, braces, and handrail structure, it has improved safety and ease of handling in terms of assembly and disassembly work. It is characterized by ensuring the following.

以下、本考案を図面に基いて説明する。 Hereinafter, the present invention will be explained based on the drawings.

Figure). In the same figure, indicates the lowest scaffolding structural unit, which is a scaffold constructed between a plurality of building frames 6 arranged in parallel along the outer surface of building A and each of the adjacent building frames. A plate 3 is provided. An H-shaped frame is used for this building frame 6. That is, it has a pair of construction members 6b, 6b' and a horizontal member 6a that connects the substantially middle portions of both members, and the scaffold board 3 is constructed on the horizontal member 6a. A jack base 7 is attached to the lower end of the building material 6b of the lowest building frame 6.

足し設置した形をなす。 The frame scaffold of the present invention has a form in which similar structural units are installed in the required number of stages on top of this lowest stage using a joint structure 6c (fitting type) between the construction members of the building frame 6.

８は筋違、９は手摺と筋違（強度部材）の両機

を境に、その上方側と下方側に振り分けた形で設
けられる。つまり、その上方側には手摺を兼ねる
剛性枠９が、同じく下方側には筋違８が、各々付
設されるわけである。 8 is a brace, and 9 is a rigid frame that functions as both a handrail and a brace (strength member). These are the height of the scaffold board 3 level, that is, the height of the horizontal ground member 6a, between the adjacent outer building members 6b' and 6b' of the H-shaped building frame of each stage (on the side opposite to the building A). They are divided into upper and lower sides based on their location. That is, a rigid frame 9 that also serves as a handrail is attached to the upper side, and braces 8 are attached to the lower side.

上記筋違８としては、２本の強度部材８ａ，８
ａを予め互いの中央部でピン１０止めしてＸ字状

ようにする。 The braces 8 include two strength members 8a, 8.
A is used that is secured in advance with a pin 10 at the center of each other to form an X-shape. This brace is, for example, a gravity lock 11 attached to the outside construction member 6b' near the lowermost end and directly below the horizontal member attachment position.
11, the through holes at the ends of each member are engaged to attach the members.

剛性枠９は、筋違としての機能をも果す必要か

その上端付近に付設のグラビテイ・ロツク１４，
１４に係止させて取付けるようにすればよい。 Since the rigid frame 9 needs to also function as a brace, it must be configured to include at least a rectangular frame body. This rigid frame 9 is basically a rectangular frame, and from the viewpoint of strength, for example, as shown in FIG. 2 and furthermore, as shown in FIG.
It is preferable to add a reinforcing member 12 in a diagonal direction or the like. In the case of this rigid frame as well, the through holes of the upper and lower mounting brackets 13 protruding on both the left and right sides of the frame are connected to the gravity locks 14 provided directly above and near the upper end of the horizontal member mounting position of the outer construction member 6b'. ，
14 and be attached.

上記グラビテイ・ロツクと透孔は、その設ける
側を互いに逆にすることもできる。 The gravity lock and the through hole can also be provided on opposite sides.

なお、前記建枠の内側（建造物Ａ側）について
も、隣り合う建地部材６ｂ，６ｂ間（足場板３よ
り上方）に手摺枠１５、或いは通常使用される手
摺材を設けることが推奨される。 Furthermore, regarding the inside of the building frame (building A side), it is recommended to provide a handrail frame 15 or a commonly used handrail material between the adjacent building members 6b and 6b (above the scaffolding board 3). Ru.

以上のような構成になる本考案の枠組足場は、
次のようにして組立て、設置される。すなわち、

このようにして下方から一段ずつ順に組上げてゆ
く。解体するときには、これと全く逆の手順を踏
んで最上段から順次下方へ作業を進めてゆく。 The framework scaffold of the present invention, which has the above structure,
It is assembled and installed as follows. That is,
Install multiple building frames 6 at the bottom and connect them to braces 8
The scaffold board 3 is then stabilized and the rigid frame 9 is set from the inside. Next, the second tier building frame 6 is connected on top of this lowest tier building frame 6, and the braces 8 are attached and the scaffolding boards 3 are erected in the same manner as described above.
In this way, they are assembled step by step from the bottom. When dismantling it, the process is completely reversed, starting at the top and working downwards.

このような組立て、解体の作業において、作業

がある状態で行うことになり、安全性の高い条件
下での作業となるものである。 In such assembly and disassembly work, workers stand on each scaffold board 3 and move the building frame 6 and braces 8 of the tier directly above the tier concerned, just as when using conventional gate-type building frames 1. It is necessary to carry out work such as installation or removal, but all of this work for each step is done by attaching a rigid frame 9 that serves as a handrail to the step being worked on.
The work will be carried out under highly safe conditions.

としての機能をも期待できるから、別途手摺をと
る必要がなく、その手間が省かれる。 The frame scaffold of the present invention also has braces in the frame scaffold that maintain the horizontal rigidity of each tier. It has a structure divided into a rigid frame 9, and by handling these separately during assembly and disassembly, a worker standing on the scaffolding board 3 can easily perform attachment and detachment work in a comfortable position. Furthermore, since the rigid frame 9 can be expected to function not only as a brace but also as a handrail, there is no need to provide a separate handrail, which saves time and effort.

しかも、Ｘ字状筋違８と剛性枠９とを合せれ
ば、第１図の例にみられるように相隣れる建枠の
建地部材間の略々全面にまたがる形の筋違２より
むしろ強度的に有利な構造が得られる。 Moreover, if the X-shaped braces 8 and the rigid frame 9 are combined, the braces 2 that span almost the entire surface between the construction members of adjacent building frames, as shown in the example in Fig. Rather, a structure advantageous in terms of strength is obtained.

更に本考案の枠組足場は、第１図の例にあるよ
うに最上段に手摺支柱４をセツトする作業が不要
であるという、付随的なメリツトもある。 Furthermore, the framework scaffold of the present invention has the additional advantage that it does not require the work of setting the handrail support 4 at the top step as shown in the example of FIG.

以上に説明したように本考案の枠組足場は、組
