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 the building frame, etc., and braces 2, 2 are placed between 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 set as the lowest stage.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 number of stages until it is placed on the topmost building frame 1. A post 4 is erected and a handrail 5 is set on it.
ところが、この種の足場は組立或いは解体作業

には、ジヤツキベース７が装着される。 FIG. 2 is a perspective view showing a framework scaffolding according to an embodiment of the present invention. In the same figure, indicates the lowest scaffolding structural unit, which consists of a plurality of building frames 6 arranged in parallel along the outer surface of the building and scaffolding boards 3 constructed between adjacent building frames. Be prepared. An H-shaped frame is used for this building frame 6. That is, it has a pair of construction members 6b, 6c and a horizontal material member 6a that connects the substantially middle portions of both members, and the scaffold board 3 is constructed on the horizontal material member 6a. A jack base 7 is attached to the lower end of the building material 6b of the lowest building frame 6.

In addition, the joint structure is based on construction material 6.
Generally, a pin 6d is attached to the upper end of b, 6c to be inserted into the lower end of the construction member immediately above.

れることがある。 Both 8 1 and 8 2 are rigid frames that have the functions of both a handrail and a brace (strength member). In other words, the rigid frame is the building material 6 on the outside (on the side opposite to the building side) of the adjacent H-shaped building frames of each stage.
Construction members 6 between b and 6b and inside (building side)
between c and 6c, respectively, are provided on the upper side of the scaffold board 3 level (the outer one is 8 1 ,
(The inner one is indicated by 8 2 ). Since this rigid frame must also function as a brace, it must include at least a rectangular frame made of a round tube, a square tube, or the like. All of them have a rectangular frame as a base, and from the viewpoint of strength, for example, as shown in Fig. 2, and furthermore, as shown in Fig. 3 A to C, there are Preferably, a reinforcing member 11 is added. However, regarding the inner rigid frame 82 , it is preferable that the number of reinforcing members 11 be at least as simple as possible, as shown in FIG. 2 or 3, so as not to interfere with work on the wall surface of the building. Regarding the outer rigid frame 81 , there is no need to take such consideration, and only the scaffolding strength needs to be considered. The incorporated structure can also be adopted without any problem. Note that a curing sheet may be attached to the outer rigid frame 81 to prevent it from falling.
このような剛性枠は、その左右両側の縦部材の
上下位置に透孔付の取付片１０が突設してあり、
この取付片１０をそれぞれ、建地部材６ｂ（また

取付片１０を抜止めするものである。 Such a rigid frame has mounting pieces 10 with through holes protruding from the upper and lower positions of the vertical members on both the left and right sides thereof,
Each of the mounting pieces 10 is attached to the building material 6b (or 6c) by being engaged with a locking fitting 9 provided facing inward. This locking fitting 9
A locking pawl 9b elastically protrudes from a short shaft 9a, and the locking pawl 9b prevents the attachment piece 10 fitted into the shaft 9a from coming out.
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、
まず最下段の複数の建枠６を設置し、これに足

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,
First, a plurality of building frames 6 at the lowest level are installed, a scaffold board 3 is erected thereon, and then outer and inner rigid frames 8 1 and 8 2 are set from within the scaffold. Next, the second tier building frame 6 is connected to the bottom tier building frame 6, and the scaffolding boards 3 are erected in the same manner as described above, and in this way, the tiers are erected one by one 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
者は従来一般の門型建枠１使用のときと同様、各
足場板３上に立つて当該段の直上の段の建枠６の
設置或いは取外しなどの作業を行う必要がある
が、こうした各段毎の作業は全て、その作業中の
段に手摺としての役目を果す剛性枠８1，８2があ

の作業となるものである。 In such assembly and disassembly work, the worker stands on each scaffolding board 3 and installs or removes the building frame 6 on the tier directly above the tier, just as in the case of conventional gate-type building frames 1. It is necessary to carry out this work, but all of this work for each step must be done with the rigid frames 8 1 and 8 2 that serve as handrails on the step being worked on, making it highly safe. The work will be done under certain conditions.
また本考案の枠組足場においては、剛性枠８1，
８2が各段の水平方向の剛性を保つ、つまり枠組
足場における筋違機能を果すものであり、この剛
性枠による構造は第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に対し強度的に遜色のないものが得られ
る。 Furthermore, in the framework scaffold of the present invention, the rigid frame 8 1 ,
8 2 maintains the horizontal rigidity of each tier, in other words, serves as a brace in the framework scaffolding, and the structure using this rigid frame is able to maintain the horizontal rigidity of each tier, and as shown in the example in Figure 1, the construction of adjacent building frames It is possible to obtain a brace 2 that is comparable in strength to the brace 2 that spans substantially the entire surface between the members.
しかもこの剛性枠は、各段において足場板３レ
ベルの上方側にあり、足場板３上に立つ作業者が
無理のない態勢にて容易に脱着作業を行える。そ
の上、剛性枠は筋違ばかりでなく手摺としても機
能するから、別途手摺をとる必要がなく、その手
間が省かれる。 Moreover, this rigid frame is located above the level of the scaffolding board 3 at each stage, so that a worker standing on the scaffolding board 3 can easily attach and detach the scaffolding in a comfortable position. Furthermore, since the rigid frame functions not only as a brace but also as a handrail, there is no need for a separate handrail, which saves time and effort.
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 an additional advantage in 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
立、解体の作業に関し高い安全性を保証し得る
他、すぐれた作業性を備え、強度的にも高い信頼
性を有しており、その実用価値はきわめて大き
い。 As explained above, the frame scaffold of the present invention not only guarantees high safety during assembly and disassembly work, but also has excellent workability and high reliability in terms of strength. The value is extremely great.
