A plan view, (c) is a side view. In the baseboard for scaffold boards according to the present invention, a baseboard body 1 made of a steel plate is attached to a vertical member 6 of a building frame 5 of a frame scaffold by a baseboard mounting bracket 4 comprising a mounting substrate 2 and a displacement preventing member 3. It is made like this.

  A part of the building frame 5 is shown in FIG. 1 and FIG. 2, and is composed of a pair of left and right vertical members 6, 6 and a horizontal member 7 connecting the vertical members 6, 6. Frames 5 are arranged opposite to each other at regular intervals, crossing striations 16 and 16 are stretched between opposing longitudinal members 6 and 6 of opposing building frames 5 and 5, and scaffolding is provided between both lateral members 7 and 7. While spanning the plate 8, the building frame 5 is added upward, and the frame scaffolds are sequentially assembled in a multi-stage shape.

  As can be seen from FIGS. 1 to 3, the skirting board body 1 includes a horizontal plate portion 9 that is placed on the end of the beam side of the scaffold plate 8, and a vertical plate portion 10 that rises from the outer end of the horizontal plate portion 9. The horizontal plate portion 9 has a width of about 1/3 of the width of the scaffold plate 8 and a length substantially the same as the length of the scaffold plate 8. The width is narrower than the width of the horizontal plate portion 9, and the length thereof is longer than the horizontal plate portion 9 by the length of both ends protruding from the both ends of the horizontal plate portion 9, and the both end protruding portions 10a. , 10a are provided with locking pin hook holes 11, respectively. Further, the front edge portion of the horizontal plate portion 9 and the upper end edge portion of the vertical plate portion 10 are folded back to form the folded edge portions 9o and 10o, respectively.

  As shown in FIGS. 4A to 4C, the mounting board 2 is formed in a vertically long rectangular shape by a thick iron plate, and on the upper side, on the lower end side of the vertical member 6 of the building frame 5 Lock pin insertion holes 13 that can be inserted into the cross-reverse mounting lock pins 12 projecting at the top and bottom are provided in two locations, and a base plate mounting locking pin 14 projects from the front of the lower end. Yes. The skirting board mounting locking pin 14 includes a shaft portion 14a and a large-diameter head portion 14b formed at a tip portion thereof. The reason why the lock pin fitting insertion holes 13 are provided at two positions in the upper and lower positions is that the position of the lock pin 12 for mounting the different cross bars protruding on the vertical member 6 of the building frame 5 is usually higher depending on the type of the building frame 5 This is because there are two types of low and low positions so that the two types can be handled. In this embodiment, the building frame 5 of the type in which the locking pin 12 for installing different cross bars is provided at a low position is shown. The state in which the lock pin 12 is provided at a high position is indicated by an imaginary line in FIG.
