The frame assembly scaffold 10 includes a plurality of building frames 12 arranged to face each other at a predetermined interval. The plurality of building frames 12 are opposed to each other in the left-right direction as seen in FIG. For example, as shown in FIG. 2, the building frame 12 includes a pair of left and right pipe-shaped columns 14 and a cross member 16 that is laid between upper ends of the pair of left and right columns 14 in the height direction. In this embodiment, for example, a torii type building frame is used as an example of the building frame 12.

As shown in FIG. 1, a cross brace 18 is attached between adjacent columns 14 between the plurality of building frames 12. The cross brace 18 is diagonally formed by a pair of diagonal members 18 a and is attached between the columns 14 of the adjacent building frames 12. And the scaffolding board 20 as a work floor is constructed between the cross members 16 which the adjacent building frames 12 oppose.
Furthermore, between the adjacent support | pillars 14 between the some building frames 12, the handrail 22 as a horizontal horizontal member is constructed, for example. The handrail 22 is installed, for example, at a height of 85 cm from the upper surface of the scaffold plate 20. The handrail 22 may be installed at a height of 85 cm or more.

Further, between the adjacent columns 14 between the plurality of building frames 12, a bridge 24 is installed as a horizontal horizontal member. The flange 24 is installed at a height of, for example, 40 cm from the upper surface of the scaffold board 20. The said person may be installed in 35 to 50 cm in height.
A skirting board 26 is erected on the scaffolding plate 20 so as to extend on both sides in the width direction of the scaffolding plate 20 and in the longitudinal direction between the adjacent columns 14 between the plurality of building frames 12. . The skirting board 26 is formed with a length in the width direction of, for example, 20 cm. The width of the skirting board 26 is set so that the height from the upper surface of the scaffolding board 20 to the upper end of the skirting board 26 is, for example, 15 cm or more.

  While the scaffolding plate 20 is laid between the adjacent cross members 16 of the adjacent building frames 12, the building frame 12 is sequentially touched upward, whereby the multistage frame scaffold 10 is sequentially assembled. In addition, between the some adjacent building frames 12 arrange | positioned at the lowest step, as shown, for example in FIG. 1, the scaffolding board 20, the handrail 22, the skirt 24, and the baseboard 26 are not installed.

Next, in the present embodiment, a handrail 22 used as an example of a horizontal horizontal member and an attachment structure between the handrail 22 and the building frame 12 will be described below with reference to FIGS.
First, the structure of the handrail 22 will be described. The handrail 22 includes, in particular, a handrail body 28 having a length direction, for example, as shown in FIG. The handrail main body 28 is formed in a pipe shape, for example. At one end and the other end in the length direction of the handrail main body 28, for example, substantially L-shaped attachment portions 30a and 30b are disposed, respectively. The attachment portions 30 a and 30 b are attachment portions when the handrail 22 is attached between the struts 14 facing the building frame 12.

  Since the attachment portions 30a and 30b have the same structure, the one attachment portion 30a will be described in detail. That is, the attachment portion 30a includes a support piece 32a and an attachment piece 34a supported by the support piece 32a in a predetermined posture. The support piece 32a and the attachment piece 34a are each formed in a substantially rectangular plate shape. The support piece 32 a is disposed at one end in the length direction of the handrail body 28 and in a direction orthogonal to the length direction of the handrail body 28. The handrail main body 28 is fixed by, for example, fixing means such as welding at a position separated by a predetermined length L from one end in the longitudinal direction of the support piece 32a to the other end side (particularly, for example, see FIG. 6).

The attachment piece 34a has, for example, a circular insertion hole 36a as an insertion portion at the approximate center thereof. One end in the longitudinal direction of the attachment piece 34a is connected to the other end in the longitudinal direction of the support piece 32a, and is formed in, for example, a substantially L shape. In this embodiment, the support piece 32a and the attachment piece 34a are integrally formed of, for example, a metal material. Similarly, the other attachment part 30b is also comprised by the support piece 32b and the attachment piece 34b which has the fitting insertion hole 36b.
The support pieces 32a and 32b are arranged so that the attachment pieces 34a and 34b are arranged substantially parallel and horizontally with the handrail body 28 of the handrail 22 and are brought into contact with the column 14 of the building frame 12, respectively. It is to support.

Next, the attachment structure 40 between the handrail 22 and the building frame 12 will be described. For example, as shown in FIGS. 6 and 7, the mounting structure 40 is disposed at the mounting portions 30 a and 30 b of the handrail 22 that are attached to the column 14 of the building frame 12 and at a predetermined position in the height direction of the column 14. And a connection portion 42 that is detachably connected to the attachment portions 30a and 30b.
For example, as shown in FIGS. 2, 5, and 6, the connecting portion 42 protrudes from the column 14 of the building frame 12 in a direction substantially orthogonal to the column 14, and fits the mounting portions 30 a and 30 b described above. The connecting shaft member 44 is inserted into the insertion hole 36a or 36b. The connecting shaft member 44 is provided with a notch groove portion 46 having a predetermined length from the axial tip to the base side of the connecting shaft member 44.

  A stopper member 48 having a longitudinal direction is disposed between the wall surfaces 44a and 44b of the connecting shaft member 44 facing each other through the notch groove portion 46. The stopper member 48 has, for example, an oval long hole 48a provided in the substantially central portion in the longitudinal direction so as to extend in the longitudinal direction. In particular, as shown in FIG. 5C, the stopper member 48 is rotatably supported by a pivot member 50 inserted through the long hole 48a. Therefore, the stopper member 48 is actuated so that a part of the stopper member 48 can protrude from the notch groove portion 46. Since the pivot member 50 is inserted into the long hole 48a of the stopper member 48, the stopper member 48 supported rotatably is movable in the long diameter (long axis) direction within the long hole 48a. Yes.

In this embodiment, when the handrail 22 is attached to the column 14 of the building frame 12, for example, as shown in FIG. 6, FIG. 7, and FIG. 8, in the fitting insertion hole 36a (36b) of the attachment piece 34a (34b). The connecting shaft member 44 and the stopper member 48 are inserted. At this time, the stopper member 48 is held in a posture position that is oriented in the same direction as the axial direction of the connecting shaft member 44, so that the stopper member 48 does not protrude from the notch groove portion 46.
Then, when the stopper member 48 is rotated in the radial direction of the pivot member 50 around the pivot member 50, the stopper member 48 is in a state of hanging downward (vertical direction) due to gravity. At this time, since the stopper member 48 protrudes from the notch groove portion 46, the attachment portion 30 a (30 b) is prevented from coming off from the axial direction of the connecting shaft member 44. That is, the handrail 22 is locked so as not to be detached from the column 14 of the building frame 12. After the handrail 22 is attached to the support column 14, the handrail 22 is used as the support column of the building frame 12 unless the stopper member 48 is returned to the position of the notch groove 46 in the same direction as the axial direction of the connecting shaft member 44. 14 will not deviate.
