In this way, when the scaffold 20 is installed using the fixture 30 , a gap 40 of several centimeters or more is formed between the scaffolds 20 . There is a risk that a worker's foot may fall through the gap 40 and be injured, or a tool, material, etc. may fall, injuring a worker below, or damage to a facility under work.

In order to solve this problem, the following patent document 1 includes a coupler and safety wings extending outward from both sides of the coupler, wherein the coupler includes a pair of inclined parts spaced apart from each other, and the pair of inclined parts An auxiliary scaffold comprising a horizontal part connecting the lower ends, a body detachably coupled to the coupling hole, and a fixing clip having a tension protrusion extending downward from both ends of the lower end of the body, disposed between adjacent scaffolding scaffolds A tension protrusion is tension-coupled to the scaffold frame of a cylindrical shape, and an auxiliary scaffold is disposed in the space between the adjacent scaffolding scaffolds to remove the empty space, wherein the coupling part has a pair of inclinations toward the bottom. The horizontal width between the parts is increased, and a coupling groove is formed on the upper surface of the body, the horizontal width of which increases downward so that the coupling member is male and female in a sliding coupling manner, and the safety wing is at the upper end of the inclined part of the coupling member. Disclosed is a diaphragm plate for scaffolding, which extends horizontally in the and is formed to be inclined downward, and the pair of tension projections are fixed to the scaffold frame while the inlet is opened by the scaffold frame and restored to its original state.

In addition, in Patent Document 2, it extends in the left-right direction, extends in the left-right direction from the center, and extends in the left-right direction and a metal upper plate having a downwardly protruding groove, fixed to the lower part of the groove of the upper plate, and the side surface of the cover It has an ∩ shape when viewed from, and includes one or more clips that can be fastened to the connection pipe of the safety footrest, and the two regions of the upper plate separated by the groove are each perpendicular to the longitudinal direction of the groove when viewed from the side of the cover. Disclosed is a cover for a safety scaffold gap of a scaffold that forms an angle of 70 to 80° with the vertical center line.

The gap plate or cover disclosed in Patent Documents 1 and 2 covers the gap formed between the scaffolds of the scaffolding, thereby obtaining an effect of preventing a safety accident or falling of a tool.

By the way, in the case of the gap plate or cover disclosed in Patent Documents 1 or 2, the clip fastened to the pipe of the scaffolding protrudes long at the lower part of the safety plate or the upper plate to form a shape integrally with the safety plate or the upper plate, so that the gap plate or The cover is very inconvenient to handle.

In particular, in the case of a large construction site, the number of covers to be installed increases from hundreds to thousands or more. In addition, it requires a lot more space for loading, and it is difficult to stably load, which can cause safety accidents during the loading and transport process. There is a problem in that a relatively large amount of manpower, time and cost is required.

On the other hand, in the case of the fixing clip of Patent Document 1, since it may be fastened in a sliding form on the safety plate, a method of disassembling the clip during storage or transport and then fastening at the time of operation may be applied. However, since it is very cumbersome to combine or disassemble the clip to the safety plate after severe cold or rain in winter, the bonding or disassembling operation itself may be a great burden to the operator, and the clip may be lost during storage and transport after disassembly. There is a problem in that the maintenance is not easy.
