Description

Folding type system scaffolding

The present invention relates to a folding system scaffolding, and more specifically, the folding system that can be easily folded with a minimum of volume and thus can be easily installed, improves transportability, and can easily expand a work space. It's about scaffolding.

In general, in the construction site and industrial site, if you want to carry out the aerial work, a ladder consisting of a fixed, straight, A-shaped, H-shaped, folding, etc. structure is used. However, these ladders are made for the purpose of climbing up and down high places, and they are not fixed stably during height work and do not provide a work space where the worker can stand stably. There is a problem that occurs frequently.

Meanwhile, according to the Seoul Metropolitan Government and the Ministry of Employment, the number of casualties caused by ladder accidents in the last 10 years was 39,059, of which 71%, or 2,7739, were seriously injured and 371 died. Announced. In addition, the construction industry said more than 40% more accidents caused by ladders and deaths in the construction industry. In order to prevent such safety accidents, the Ministry of Employment and Labor and Safety and Health Corporation prohibited the use of ladders for work purposes on various sites as of January 1, 2019. That is, when working in a high space, the general ladder consisting of a fixed, straight, A-shaped, H-shaped, folding, etc. structure is prohibited use.

Accordingly, in the future, when the working platform is installed at the top of two ladders at the height of the aerial work, for example, only the form scaffolding and the horse scaffolding can be used, and only the form in which the working platform is stably fixed is allowed.

On the other hand, scaffolding (frame scaffolding and horse scaffolding) used in aerial work can be divided into fixed and mobile.

Fixed scaffolds can be installed to meet the required work at the location where work is needed, which can increase efficiency in certain operations, but it is difficult to move the scaffold to another location for other work, and in some cases dismantle the scaffold again. Since it has to be assembled, there is a problem that the overall construction time is increased.

On the other hand, mobile scaffolding generally has wheels attached to the fixing part of the scaffolding, and it is easy to move to various work spaces, which reduces the construction time. It is becoming.

Meanwhile, in this mobile scaffolding, a scaffold having a foldable structure that is manufactured to be folded in a specific form to reduce its volume has been developed, and a portion of the structure is folded so that the volume is reduced to facilitate storage and handling. The folding scaffolding (Korea Registration Utility Model 20-0358429) has been proposed.

1 is a perspective view of a conventional folding scaffold.

Referring to FIG. 1, the conventional folding scaffold 100 has two holding rods 1 spaced apart from each other by a predetermined distance, and a transverse side 2 formed at regular intervals between the holding rods 1. Frame (3) is formed, the two side frames (3) are installed facing each other at a predetermined distance apart, one or more connecting rods (4) on one side holding rod (1) of each side frame (3) One side end of each is installed to be rotated through the sleeve (8), the other end of each of the connecting portion 4 is fastened to be rotated by the sleeve (8), the top of each side frame (3) The footrest 6 is provided in the transverse 2 as a fastening ring 5, and is comprised.

However, the conventional folding scaffold has a structure in which the connection between the longitudinal shaft frames 3 is folded in half, and the transverses 2 between the transverse shaft frames 3 are fixed in the longitudinal direction only. Having a folding structure, even in the state where the scaffold is finally folded, there is a problem that the volume of the transverse direction does not decrease, thus making it difficult to store and handle.

The close fixing part 130 is screwed to the thread (22, 32) formed on the outer side of the folding portion 100 of the horizontal member 20 and the brace 30 so as to be in close contact with the outside of the fixing part (120). The government 120 is a part to be fixed in a state coupled with the rotating unit 110.

That is, in the separated state of the horizontal member 20 and the brace 30 or the state of being separated, the thread 35 of the outer circumferential surface of any one or both portions of the separated portion of the horizontal member 20 and the brace 30. When the insertion part 122 of the fixing part 120 is inserted into the fixing groove 113 in the state that the screw is coupled to the rotating part when the close fixing part 130 is screwed to be in close contact with the side of the ring part 121 Fixing part 120 from 110 will be able to maintain a fixed state that can not be easily separated.

On the other hand, although not shown in the drawing to remove the horizontal member 20 and the brace 30 (when to fold) close the contact fixing part 130 from the fixing part 120 to release the contact state, In this case, a stopper (not shown) is further formed on the outer circumferential surfaces of the horizontal member 20 and the brace 30 so that the close fixing part 130 screwed to the threads 22 and 32 is fixed at a specific position so that the retracting member 130 does not retreat any more. It may be provided. The stopper (not shown) may protrude to a part of the outer circumferential surface so that the end of the close fixing part 130 is locked, thereby limiting the movement of the close fixing part 130.

FIG. 13 is an exploded perspective view illustrating additional components installed in the folding system scaffold configuration of FIG. 2; FIG.

Referring to FIG. 13, the folding system scaffold of the present invention includes a vertical member 10, a horizontal member 20, a brace 30, and a footrest 40, but includes a wheel 50, a fall prevention member 60, and a hand. Rail 70 and ladder 80 may be further included.
