Scaffolding structure equipped with an assembly error prevention mechanism and a displacement tolerance mechanism

Abstract

The present invention provides a scaffolding structure installed along the exterior wall of a building that is equipped with an assembly error prevention mechanism and a displacement tolerance mechanism that physically prevents misassembly of the treads and can absorb relative displacement with respect to the building. [Solution] This scaffolding structure has an asymmetrical engagement part between the support column and the tread that allows fitting only in a specific orientation, and is equipped with a locking mechanism that operates only when properly positioned due to its own weight or load. By configuring it so that the tread is not stably supported in an incorrectly assembled state and cannot be used as a horizontal floor, the incorrect assembly of the tread is physically eliminated. Furthermore, by providing a displacement absorption mechanism at the wall connection part that absorbs relative displacement with the building, stress concentration due to external forces is reduced and safety is improved.

Description

Technical Field

[0001] The present invention relates to a scaffold structure used in construction work and the like, and particularly to a scaffold structure having a mechanism for physically preventing misassembly of tread boards and a wall connection structure capable of absorbing relative displacement with a building.

Background Art

[0002] In conventional scaffold structures, when installing tread boards between columns, it was necessary to install the tread boards in the correct orientation depending on the experience and attention of the workers. Therefore, even when the tread boards were installed in the wrong orientation, it was difficult to distinguish them visually, and there was a risk that the tread boards would fall off or become unstable during use.

[0003] Also, in the scaffolds of high-rise buildings, relative displacement occurs between the building and the scaffold due to strong winds, earthquakes, etc., and excessive stress concentrates on the wall connection part, resulting in a problem that the safety of the entire scaffold is reduced. Problems to be Solved by the Invention

[0004] In view of the above problems, an object of the present invention is to provide a scaffold structure that structurally eliminates misassembly of tread boards and functions as a stable work floor only when arranged in the correct position. Another object is to reduce stress concentration due to external forces and improve safety by providing a wall connection structure capable of absorbing relative displacement with a building. Means for Solving the Problems

[0005] The scaffold structure of the present invention includes a plurality of columns and tread boards installed between these columns, and an engagement portion having an asymmetric shape that can be fitted only in a specific orientation is provided between the tread boards and the columns.

[0006] The tread board has a lock mechanism that operates only by its own weight or working load in the normal arrangement state, and in the irregular arrangement state, the tread board is not stably supported by the column and cannot be used as a horizontal floor.

[0007] Furthermore, the scaffolding structure of this invention includes a wall tie section that connects the building and the scaffolding, and the wall tie section is provided with a displacement absorption mechanism that allows for relative displacement between the building and the scaffolding.

[0008] As a result, the treads function not only as a work platform but also as structural elements that contribute to the horizontal rigidity of the entire scaffolding, improving stability against external forces. Effect of the design

[0009] According to this invention, since misassembly of the footboards is physically impossible, a safe scaffolding structure can be constructed without relying on the attention of the assembly worker.

[0010] Furthermore, by incorporating a displacement absorption mechanism in the wall tie section, stress concentration caused by wind loads and relative displacements during earthquakes can be reduced, thereby improving the overall durability and safety of the scaffolding.
