DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entire construction work (carpenter, roof, plasterer, outer wall, painting, electricity, plumbing work, etc.) under construction on a holding scaffold for construction work, resulting in a personal injury due to a crash during work. The present invention relates to a metal working floor for a holding scaffold having a function of safely performing work with the aim of reducing personal injury and property damage accidents due to falling of members, power tools, props, etc., and improving work efficiency. .

[0002]

2. Description of the Related Art Conventionally, a wooden or metal scaffold plate is used as a work floor in order to safely perform a work on a hugging scaffold, but it is assembled horizontally with a single pipe or a scaffolding log. Because it is used on two cloths (hereinafter referred to as cloth), the contact surface between the wooden or metal scaffolding plate and the cloth is very small, so it is easy to cause sideslip, tilt, jump, etc. Use wires, rubber bands, etc. as a method of fixing or tightening, but loosen during work and the danger is large, it can not be used as a work floor, it is dangerous but there is no work floor At present, work is unavoidably carried out on horizontal cloths.

[Problems to be solved by the invention]

(B) As a general rule, work on two horizontally laid cloths on a single pipe with no working floor or a holding scaffold assembled with scaffolding logs is prohibited, especially in urban areas. The site is too small, and the distance between existing buildings and structures under construction and the building under construction or the building under construction is narrow, and it may not be possible to assemble the scaffolding on one side or the main scaffolding, which is dangerous. However, the work has been unavoidable for decades on two horizontally assembled cloths without a work floor. (B) Due to the work on two cloths, my feet were tired and painful during long hours of work. (C) Since the contact surface between the two cloths and the feet was small, the balance of the body was easily lost during the work, and excessive force was applied to the body, resulting in fatigue and pain. (D) In recent years, the number of wooden buildings has increased to three, and the number of steps has been increased, and the risk of working on two cloths has become higher. (E) During work, it may be necessary to temporarily place components, power tools, props, etc. on the scaffold temporarily,
Scaffolds are shaking, causing them to slide off the top of the two cloths, resulting in an increase in personal injury and property damage caused by falling. (F) In rainy weather, after rain, in frost, in winter, etc., since two cloths are wet, the number of accidents resulting in personal injury due to falling from the foothold during work has increased. (G) During the work, since the work is performed while checking the feet, the progress of the work is poor. In particular, the number of women engaged in construction work in recent years has increased, and the risk has increased. (H) When attaching the bracket to the pipe scaffold, the height of the bracket tends to be uneven, and time loss increases. (I) The joints of the scaffold plates used as the work floor on the brackets are superimposed, so that a level difference occurs, and there is a danger that the feet will trip during work. (V) It takes time to use a wire, a rubber band, or the like to fix a scaffold plate as a work floor on the bracket scaffold to the bracket. (R) Because the bracket's oblique support is at the bottom,
It is very dangerous because you may hit your head or the like during the lower work and lose your balance. (E) In the bracket scaffold, when the scaffold is shaken, the tip of the bracket hits the outer wall and fittings of the building, and the outer wall and fittings of the finished building may be damaged. (W) When the bracket is attached to the pipe scaffold, the bracket enters into the direction of the building, so the work interval becomes narrow and the work is difficult. The present invention has been made to eliminate these disadvantages.

【The invention's effect】

(B) A metal scaffold can be placed on the upper part of two cloths that are assembled horizontally on the hugging scaffold, and can be completely fixed. Therefore, even on construction sites where the distance between adjacent buildings and structures is narrow. If it is possible to build a hugging scaffold, it is possible to secure a work floor, so that work can be performed safely. (B) Compared to work on two cloths, the legs are not tired and the body does not exert excessive force during the work, and the work can be performed easily, which leads to an improvement in work efficiency. (C) Since the work can be safely performed even on the hugging scaffold, the construction period is shortened and the cost is reduced. (D) During work, members, electric tools, props, etc. can be temporarily placed on the work floor, so that even if the scaffold sways, etc., it is possible to prevent them from falling, Can reduce personal injury and property damage accidents. (E) During work such as rainy weather, after the rain, frost, winter, etc., it is possible to reduce the number of accidents caused by a fall caused by slipping the foot. (F) Brackets-In the side scaffolds, there are many cases where it is difficult to secure the work floor, such as in the shirt box or bay window, but the brackets are removed, two cloths are attached to the building, and a part of the scaffold is held. And a working floor can be secured. (G) The work height can be freely selected by holding the scaffold at an arbitrary height. (H) The hugging scaffold can be used even when a slight graded scaffold is required. (I) Since the anti-skid hardware and the fixed hardware can be folded and stored on the back surface of the metal scaffold plate, the storage place for stacking may be the same space as a general scaffold plate. (V) Basically, the land spacing is about 1.8 m, and the metal scaffolding plate is also short, so it is lightweight and easy to handle. (L) The tightening bolt is screwed into the anti-skid hardware, so it does not hinder the lower work. (Iii) The anti-skid hardware folded and stored during small transport of the metal scaffolding plate does not jump out because it is held down by the holding hardware. (C) It can be used as a work floor by placing it on a holding scaffold assembled with scaffold logs. (F) Since the anti-skid hardware and the fixed hardware are stored on the back surface of the metal scaffold plate, it can be used as a general short scaffold plate.
