[0004]
The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is not only to easily and quickly fold, but also to install safely without fear of rainfall or flapping due to wind. To provide a temporary roof for scaffolding.
[0005]
[Means to solve the problem]
The temporary roof for a scaffold according to the present invention comprises a single pipe mounting means mounted on an upper end of one pillar of the uppermost scaffolding frame, and a sheet covering member mounted on an upper portion of the other pillar of the building frame. A first single pipe attached to the single pipe mounting means and arranged along one upper side of the building frame; and a first single pipe attached to the seat covering member and along the other upper side of the building frame. In a temporary roof for scaffolding, comprising: a second single pipe that is arranged and movable outward and a sheet that is mounted by the first and second single pipes, the sheet mounting member includes: A vertical frame portion attached to the upper portion of the pillar of the building frame, a slide portion slidable along the vertical frame portion, and a base end portion rotatably attached to the slide portion and a tip end portion. An arm with a single tube holding tube and one end rotatably attached to the upper end of the vertical frame And an oblique member whose other end is rotatably mounted in the middle of the arm.
[0006]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1, 2 and 3, A is a scaffolding frame, which is mainly horizontally disposed on an outer pillar A1 and an inner (building side) pillar A2 and upper ends of these pillars A1 and A2. It is composed of the attached horizontal member A3.
[0007]
At the upper end of the pillar A1 on one side (outside in the present embodiment) of the scaffolding frame A, a T-shaped bracket 1 composed of a pipe is attached. The T-shaped bracket 1 includes a mounting tube 1a inserted into the upper end of the pillar A1 and a single tube holding tube 1b integrally and horizontally mounted on the upper end of the mounting tube 1a.
[0008]
A seat covering member 2 mainly composed of a pipe is attached to the upper inside of the pillar A2 on the other side (in the present embodiment, inside) of the scaffolding frame A. The seat covering member 2 includes a vertical frame portion 2a, an arm portion 2b, and a diagonal member 2c.
[0009]
The vertical frame portion 2a is detachably fixed to the pillar A2 by a fixture 2a '. A single tube holding tube 2a "is integrally and horizontally attached to the upper end of the vertical frame portion 2a.
[0010]
A slide portion 2b 'is slidably attached to the vertical frame portion 2a, and a base end of the arm portion 2b is rotatably attached to the slide portion 2b'. A single tube holding tube 2b "is integrally and horizontally attached to the tip of the arm portion 2b. As shown in FIG. 3, the slide portion 2b 'is elastically attached to the vertical frame portion 2a. The lock pin P is locked by a lock device such as a lock pin P projecting therefrom, and is released and slidable by pushing the lock pin P.
[0011]
One end of the diagonal member 2c is rotatably attached to the upper end of the vertical frame 2a, and the other end is rotatably mounted in the middle of the arm 2b. Therefore, as is apparent from FIG. 2, by sliding the slide portion 2b 'up and down along the vertical frame portion 2a, the arm portion 2b is moved along the vertical frame portion 2a as shown by a virtual line. It is folded or positioned almost vertically with respect to the vertical frame portion 2a as shown by a solid line. Along with the movement of the arm 2b, the single tube holding tube 2b ″ provided at the end moves along a locus B.
[0012]
Reference numeral 3 denotes a seat, which covers the space between the upper part of the frame scaffold constituted by the pillar A and the building inside the scaffold. More specifically, the outer edge of the seat 3 is tied to a single tube 4 that is assembled substantially horizontally on the upper part of the outer pillar A1, and the inner edge of the single tube 4 is at the tip of the arm 2b. The sheet 3 is tied to a single pipe 5 attached substantially horizontally to the single pipe holding cylinder 2b ". The side edge of the sheet 3 is provided with, for example, a hook-and-loop fastener 3a so that it can be connected to an adjacent sheet. Has become.
[0013]
Next, attachment of the temporary scaffold of the above embodiment will be described.
First, as shown in FIG. 5, the mounting cylinder 1b of the T-type bracket 1 is inserted into and attached to the outer pillar A1 outside the building frame A at the top of the external scaffold assembled.
[0014]
Subsequently, as shown in FIG. 6, the seat covering member 2 is attached to the inside of the upper part of the pillar A2 inside the building frame A via the attachment 2a '.
[0015]
When the mounting of the T-shaped bracket 1 and the seat covering member 2 is completed, as shown in FIG. 7, the single pipe 6 is inserted into the single-tube holding cylinder 1b of the T-shaped bracket 1, and a proper tightening bolt (not shown) is used. ) Etc. and fix it. The single tube 7 is inserted into the single tube holding tube 2a "and the single tube 5 is inserted into the single tube holding tube 2b" of the sheet covering member 2, and fixed.
[0016]
Further, as shown in FIG. 8, the single pipe 4 is attached and fixed to the outer pillar A1 by a clamp 8.
[0017]
Finally, the sheet 3 is wrapped around the single tubes 6 and 7, and the outer edge thereof is attached and connected to the single tube 4 with a fastening band 9, and the inner end is attached to the single tube 5 with a fastening band 9. Connecting.
[0018]
When the mounting of the seat 3 is completed, the sliding portion 2b 'of the seat mounting member 2 is moved from the virtual line state to the solid line state as shown in FIG. Dress.
[0019]
The sheet mounting member 2 of the above embodiment is composed of a vertical frame portion 2a, an arm portion 2b, and a diagonal member 2c, each of which is a pair, and the adjacent sheets 3 are mounted independently. Although it is possible to close or close the sheet, when the adjacent sheets 3 are simultaneously operated or when the sheet 3 is provided at the outer end of the sheet located at the end of the temporary roof, the sheet covering member 2 has one sheet The book may be composed of a vertical frame portion 2a, an arm portion 2b, and a diagonal member 2c.
[0020]
【The invention's effect】
The temporary roof for scaffolds of the present invention can be easily and quickly folded, and can be safely installed without fear of rattling due to rain pools or wind.
