Description

System scaffold

The present invention relates to system scaffolding.

When constructing buildings, etc., temporary scaffolds with pipes installed vertically and horizontally are installed on the outside of the outer wall for exterior construction.

Scaffolding is a temporary temporary structure installed to work at a high place during construction, and is constructed for material transport, moving passage, work, etc. In terms of material, log scaffolding, pipe scaffolding, in terms of use, external scaffolding, internal scaffolding, and horizontal scaffolding. , dangling scaffolding, simple scaffolding, ladder scaffolding, and single-row scaffolding, double-row scaffolding, and double-row scaffolding in terms of construction methods. Recently, steel pipe scaffolding and system scaffolding are mainly used in construction sites.

In the case of steel pipe scaffolding, it is a scaffold made of steel pipe with aluminum plating on the surface, and can be freely assembled using connecting hardware such as clamps or fasteners. However, due to the narrow width of the footrest and the difficult installation of the passage, workability may be reduced, reliability is reduced due to non-standardization, and there is a high risk of falling when the operator moves and works due to the ad hoc installation.

In the case of system scaffolding, unlike steel pipe scaffolding that can be installed arbitrarily, it is a scaffold that is standardized through structural calculation and can be assembled. It has relatively high safety and is mainly used for construction of medium and large-sized buildings. Such scaffolding may be largely composed of a post installed vertically at regular intervals from the ground, a plurality of horizontal members assembled to be linked between the posts, a moving passageway, or a scaffold installed for the convenience of work.

On the other hand, the system scaffolding may additionally comprise a brace called a brace in order to improve structural strength, and this brace connects the post and the horizontal member in an inclined manner. In the case of steel pipe scaffolding, since the process of connecting the posts and the horizontal members is done manually by the operator at the work site, there is inevitably a change in the spacing between the posts or between each horizontal member, and there is inevitably a difference in the bonding position of the posts and the horizontal members. none.

As such, if the arrangement and coupling of the posts and the horizontal members are not made uniformly, accurate coupling and fixing may not be made in the process of additionally installing the braces manufactured in a certain shape, and if the gap is large, the installation itself may become impossible.

As a result, there is a problem in that the brace installed to reinforce the structural strength of the system scaffold cannot perform its role.

In addition, in order to improve the visual effect when looking at the external appearance of a building structure, structures having a streamlined curved surface or an inclined surface are increasing, away from a simple rectangular structure. However, in the case of system scaffolding, it is generally standardized and assembled in a rectangular shape.

In the case of working on various types of buildings as described above, separation from the building (mainly wall) is inevitable only with standardized system scaffolding, which inevitably lowers work efficiency and increases the risk of work.

In order to structurally reinforce this spaced part, an additional structure has to be manufactured by an operator in the field like the above-described steel pipe scaffolding, and this may cause the same or similar problems as those discussed in the steel pipe scaffolding.

It was devised based on the technical background as described above, and the present invention is connected between the H-beam and the pipe constituting the system scaffold to improve the supporting capacity, and the length can be adjusted so that the interval between the H-beam or the system scaffold is different. It is intended to provide a system scaffold that can be easily connected and firmly fixed.

In order to achieve the above object, the present invention includes a vertical pipe installed from the bottom to the top, a horizontal pipe connected between the vertical pipes, and a clamp for fixing the vertical pipe and the horizontal pipe at one end, and an H-beam at the other end. It is possible to provide a scaffold that is provided with a fixing portion connected to the clamp and the length adjustment portion is formed between the fixing portion to adjust the length is formed. In addition, the length adjusting unit may include a cover pipe connected to the other side of the clamp, a body pipe threaded inside the cover pipe, and a fixing part coupled to the other end.

In addition, the clamp may include a rotatable clamp member surrounding the vertical pipe and the horizontal pipe, a clamp bolt formed on one side of the clamp member and rotatable to fix the system scaffold, and a bracket fitted with the clamp bolt. .

In addition, the fixing part includes a fixing body fitted with the H-beam, a tightening part having a through hole formed on one side of the fixing body to be coupled to the fixing body, and a tightening protrusion formed inside the fixing body on the other side of the fixing body. can

In addition, it may include a hanger to which the bolt is rotatably fastened to one side of the fixed body.

The system scaffold according to an embodiment of the present invention can adjust the length between the H-beam and the vertical and horizontal pipes, so that the interval between the H-beam and the vertical and horizontal pipes is not constant between the H-beam and the system scaffold.
