Description

  The present invention relates to a building scaffold provided with a scaffold facing an outer wall of a building.

  Since a conventional building scaffold is provided with a scaffold so that the relative position with respect to the building does not move (see, for example, Patent Documents 1 to 4), the scaffold is provided to face the outer wall of the building. In the scaffolding, the scaffolding is also integrally fixed to the building side so as to surely prevent the outer wall of the scaffolding from falling in the perspective direction due to wind loads or the like.

Japanese Patent No. 2955251 Japanese Patent Publication No. 6-58008 JP-A-9-310481 Japanese Patent Laid-Open No. 10-18582

For this reason, for example, the construction is carried out while moving the building in the horizontal direction with respect to the scaffold, so that the scaffold and the outer wall are opposed to each other so as to be relatively movable in the horizontal direction. In building scaffolds, the scaffold cannot be fixed integrally to the building side, so a large scaffold with a larger falling moment as the height increases, or a structure for preventing falls such as a column supporting the scaffold is installed separately. It is necessary to surely prevent the scaffold from falling in the perspective direction due to wind loads, etc., and a large amount of scaffolding material is required, or a large space for installing the scaffold along the outer wall is required. There is a drawback that there is.
The present invention has been made in view of the above circumstances, and particularly a large amount of scaffolding material is used while the scaffold and the outer wall are opposed to each other and are provided for relative movement in the horizontal direction. The purpose of the present invention is to reliably prevent the scaffold from falling in the perspective direction with respect to the outer wall portion due to wind load or the like without having to secure a wide space for installing the scaffold along the outer wall portion.

A first characteristic configuration of the present invention is a building scaffold provided with a scaffold facing an outer wall portion of a building, wherein the scaffold and the outer wall portion are opposed to each other in the horizontal direction. An engagement mechanism that is movably provided and engages the scaffold and the outer wall portion so as to prevent the scaffold from falling in a perspective direction with respect to the outer wall portion is fixed to the scaffold along the relative movement direction. A guide rail and an engaging member that is detachably fixed to the outer wall so as to engage with the guide rail are configured to allow relative movement along the relative movement direction of the scaffold and the outer wall. It is in the point provided.

[Action and effect]
Without fixing the scaffold and the outer wall part to each other, the scaffold and the outer wall part are provided so as to be relatively movable in a horizontal direction in a posture facing each other, and the scaffold and the outer wall part are arranged in a perspective direction with respect to the outer wall part of the scaffold. Since the engagement mechanism that engages so as to prevent the body from falling is provided to allow the relative movement along the relative movement direction of the scaffold and the outer wall, the scaffold and the outer wall are opposed to each other horizontally. Although it is a building scaffold that can be moved relative to the direction, there is no need to use a large amount of scaffolding materials or to secure a large space for installing a scaffold along the outer wall. By supporting it, it is possible to reliably prevent the scaffold from falling in the perspective direction with respect to the outer wall portion of the scaffold due to wind load or the like.

Then, engaging a scaffold and an outer wall portion of the engaging mechanism for preventing engage the inclination of the direction of access for the outer wall of the scaffold, and its guide rail along a relative movement direction guide rails fixed to the scaffold The length of the guide rail is such that the engaging member is detachably fixed to the outer wall portion so that the relative movement between the scaffold and the outer wall portion is allowed. By selecting, it is easy to engage so as to allow relative movement over a desired distance while preventing the scaffold from falling down.

Furthermore, since the guide rail is fixed to the scaffold and the engaging member is detachably fixed to the outer wall portion, the scaffold can be reinforced with the guide rail, and the length along the relative movement direction of the outer wall portion is relative to the scaffold. If it is longer than the length along the moving direction, by replacing the engaging member fixed to the outer wall portion that has moved relative to the position that does not face the scaffold, with the outer wall portion that moves relative to the position that faces the scaffold, In particular, without providing a long guide rail, it is easy to engage easily so as to allow relative movement over a desired distance while preventing the scaffold from falling down.

A second characteristic configuration of the present invention is that the guide rail and the engaging member are engaged with each other by providing play.

[Action and effect]
Since the guide rail and the engaging portion of the engaging member are engaged with each other by providing play, the scaffold and the outer wall portion can be smoothly and relatively moved while preventing the scaffold from falling down, and the guide rail and the engaging member are engaged with each other. The joint member can be easily attached without particularly high accuracy.

A third characteristic configuration of the present invention is that the engaging member is provided with a roller that is slidably engaged along the guide rail.

[Action and effect]
Since the engaging member is provided with a roller that is slidably engaged along the guide rail, the frictional resistance between the engaging member and the guide rail is reduced, and the scaffold and the outer wall portion can be easily formed. It can be moved relative.

Embodiments of the present invention will be described below with reference to the drawings.
