[Industrial Application Field] The present invention relates to a scaffolding board that is lightweight and has good workability that can be used for work on slate roofs, etc., and particularly relates to a scaffolding board for roofs that ensures the safety of workers on the roof. It is. [Prior Art] Figures 6 and 7 show the appearance of two types of roof scaffolding boards (hereinafter abbreviated as scaffolding boards) currently in use. Figure 6 shows a wooden scaffolding board made of American pine board or Japanese cypress, measuring 3 cm thick x 30 cm wide x 180 cm long, and weighs about 12 kg. Figure 7 shows a scaffolding board made of steel and aluminum, the size of which is as follows:
Thickness 3.8cm x width 30cm x length 200cm, weight 14Kg.
For example, it is made up of two aluminum plates 61 and 62, and has a structure that can be bent at a central portion 63. Note 6
4 and 65 are rubber anti-slips. [Problems to be solved by the invention] Conventional wooden scaffolding boards have a structure in which a single board is processed into the dimensions illustrated above, so they are heavy and difficult to transport and lift onto the roof of the workplace. However, due to its poor workability, it is rarely used in practice, and as a result, workers who step on the slate roof may fall or slide, resulting in injury (injuries) and damage to the slate roof. . This problem is the same with conventional steel and aluminum scaffolding boards. [Means for Solving the Problems] In order to solve the problems of the conventional art, the present invention uses a honeycomb core as the core material, and aluminum plates are bonded to both the upper and lower surfaces of the honeycomb core to form an integrated panel into a sandwich-like board. For example, a rubber anti-slip tape is pasted on one or both surfaces of this panel, and the panel is provided with a notch to be inserted into the base bolt of a slate roof, or a hook to be hung on a frame at the end of the panel. It has a structure in which a panel locking part is provided, and if necessary, a grip part for transportation is provided on the panel, and anti-slip material made of rubber, for example, is applied around the panel, around the notch, and around the grip part. There is. [Function] The present invention is lightweight and has anti-slip properties between the roof and the panel and between the panel and the worker's feet, ensuring safety.Furthermore, by providing a locking part between the panel and the roof, Safety as a scaffold board is guaranteed. This will be explained below with reference to the drawings. [Embodiment] FIG. 1 is a diagram showing a top configuration of a first embodiment showing the basic configuration of the present invention. The core material is a regular honeycomb core made of metal tape formed into a honeycomb shape.
A panel (generally known by the product name Hivex, hereinafter abbreviated as the panel) is made by bonding aluminum plates 10 with adhesive to the top and bottom surfaces of the panel (generally known as a product name called HYBEX, hereinafter abbreviated as the panel). The anti-slip tapes 13 and 14 are attached to prevent the panel from sliding off the handle 15 for transportation and a sloped roof. For example, when used on a slate roof, base bolts are inserted to prevent slipping. Notches 16 and 17 for measuring are provided, and edgings 11, 18, 19, and 12 made of rubber, for example, are provided around the panel, around the notches, and around the grip to prevent slipping and protect during transportation. It is structured as follows. Some other specific embodiments of the present invention are shown below. FIG. 2 shows a front view of a second embodiment of the invention. A edging 27 made of rubber or the like is adhered around the panel 20 of the aluminum honeycomb core core material, and anti-slip tapes 22 and 23 are further bonded to the upper surface of the panel 20 of the honeycomb core core material to form a scaffolding board. In this case, the edging 27 made of rubber or the like acts as a non-slip member on the lower surface side. The honeycomb core core panel 20 of this embodiment has a honeycomb core of 20 mm and a surface plate (aluminum alloy plate of 1.0 mm) on both sides in order to support the weight of the worker and to withstand local loads due to irregularities on the roof surface.
is pressed and hardened with adhesive. 25, 26
21 indicates a notch portion, and 21 indicates a rim of the grip portion 24. FIG. 3 shows a front view of a third embodiment of the invention. Anti-slip tapes 31 and 32 (however, only the top surface is shown) are attached to the top and bottom surfaces of a panel 30 made of aluminum honeycomb core material, and the surrounding area is a scaffolding board filled with resin 33. The rest is the same as in Example 2, 34 is a grip portion, and 35 and 36 are notches. FIG. 4 shows a front view of a fourth embodiment of the invention. The top and bottom surfaces and surrounding area of the aluminum honeycomb core
A panel 40 of honeycomb core core material is formed by adhesive molding with FRP, and anti-slip tapes 41 and 42 (however, only the top surface is shown) are attached to the top and bottom surfaces respectively to form a scaffolding board. The FRP honeycomb core core panel 40 of this embodiment has a structure that supports the weight of the worker and at the same time sufficiently withstands local loads due to unevenness of the roof surface. Note that 45 indicates a grip portion, and 46 and 47 indicate notches. The following table shows the results of measuring the deflection and stress of the panel face plate for the scaffold boards of the second, third and fourth examples described above. The conditions for deflection measurement are:
This is the value measured up to the concave part where the center part of the scaffold board bends from its horizontal position when no load is applied, when both ends of each scaffold board are supported and a load of 70 kg is applied to the center part.

As described above, according to the present invention, it is easy for a worker to raise a scaffolding board to a workplace on a slate roof during telecommunications work, etc., and it is easy to handle. It is effective in preventing damage to slate roofs as well as preventing damage to slate roofs. In addition, specifically, there are the following advantages. The panel is lightweight (approximately 3.5 kg) and can be easily carried around (approximately 1/8 that of conventional products). It is safe because there is a non-slip surface between the roof and the panel, and between the panel and the feet. It is also strong enough to withstand a 100kg worker standing on top of it. Furthermore, if it is used as a scaffolding board for work at high places at construction sites, it can ensure even greater safety in work at high places.
