Description

  The present invention relates to a scaffold plate on a slate roof, and more particularly to a scaffold plate on a slate roof that can perform operations such as repair, painting, inspection, and cleaning of the slate roof in a safe state at any time.

  The roofs of factories, warehouses, and station platforms are often built with slate roofs on steel structures such as purlins. On such a slate-roofed roof, it is necessary to walk on the roof for slate replacement work, inspection and cleaning of the roof and fence, painting, and the like. However, since the roofing material is a slate that is vulnerable to impact, depending on how the worker walks, the impact acts locally, and the slate is damaged and the worker falls. Therefore, conventionally, a protective net for drop prevention has been attached to the attic on a steel base material (called a purlin), and work has been carried out after taking safety measures so that even if an operator steps on the slate, it will not fall. It is done. In this case, the protection net is constructed by constructing a work table such as a scaffolding plate is placed between the stepladders. In this case, it takes time for construction / removal work of the protective net and the cost is increased. In addition, it is necessary to walk while carefully checking the top of the main building, and the slate roof itself cannot be prevented and the operator's anxiety cannot be removed.

  In addition, it is known to put a protective net on the roof (for example, Patent Document 1). However, in the case shown in Patent Document 1, the protective net interferes with the work, and the work on the roof of the net part cannot be performed. In addition, when an operator walks on the net, he / she has to walk while looking for the top of the main building, and the workability is poor.

  Therefore, it is known to build a scaffold on the roof as a technique that can be walked on the slate without being aware of the purlin under the roof (for example, Patent Document 2).

  Although it is a solid method, it has a problem that the installation to build a scaffold is large and time-consuming, and the cost is high. In particular, in the one shown in Patent Document 2, the steel pipe is in line contact with the slate roof, the friction coefficient is extremely low, and it is easy to slip. The steel pipe is in line contact, and considering the safety of the worker, it is necessary to make the steel pipe strong in strength, and it must be heavy.

On the other hand, as a simple method, scaffolding plates made of solid wood, iron or aluminum plate material, sandwich aluminum material, etc. on the construction site or roof etc. are bridged between the frames or on the slate, and the top What is made to walk is known (patent document 3).
