Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gap shielding device for a scaffold plate applied to close a gap formed between scaffold plates used at a construction site and a civil engineering site.
[0002]
[Prior art]
In general, frame scaffolds used at construction sites and civil engineering sites stand a large number of building frames consisting of a pair of vertical members and horizontal members erected between the vertical members, and the short and long sides between these building frames. A number of scaffolding plates are arranged in series along the direction.
[0003]
As shown in FIG. 9, this conventional scaffolding plate 1, 1 is provided with, for example, two plates 2, 2 in parallel along the longitudinal direction, and the front and rear ends of each plate 2, 2 are support plates 3, 3. Further, hooks 4 and 4 are provided at the ends of the support plates 3 and 3 so that the hooks 4 and 4 are hooked on a horizontal member 6 installed between the vertical members 5 and 5. It has become.
[0004]
Further, in the conventional scaffold plate 1, a slight gap A is formed along the longitudinal direction between the plates 2 and 2, and a gap B is also formed between the scaffold plates 1 and 1 along the longitudinal direction. In addition, a gap C is formed in the short direction along the horizontal member 6 between the scaffolding plates 1 and 1 along the longitudinal direction.
[0005]
[Problems to be solved by the invention]
In the conventional frame scaffold, a gap A is formed between the plates 2 and 2, and a gap B is formed between the adjacent scaffold plates 1 and 1, so that the scaffold plate 1 is interposed via the gaps A and B. During construction work, bolts, concrete fragments, etc. may fall down, which is dangerous.
[0006]
Further, when the support plate 3, that is, the scaffold plate 1 is assembled to the horizontal member 6 via the hook 4, a gap C corresponding to the diameter of the hook 4 is inevitably generated between the adjacent scaffold plates 1 and 1. Therefore, there is a risk that small items such as bolts may fall through the gap C in the same manner as described above.
[0007]
Accordingly, an object of the present invention is to provide a gap in the scaffolding plate in which the gap formed in the scaffolding plate itself and the gap formed between the scaffolding plates in the framed scaffold are reliably closed with a shielding member, and the shielding member is not detached. It is to provide a shielding device.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a gap shielding device for a scaffold board according to the present invention basically comprises a building frame composed of two vertical members and a horizontal member laid between the vertical members. In a framework scaffold in which a plurality of scaffolding frames are laid in the longitudinal direction via hooks on a horizontal member after arranging a number of building frames, and a gap is formed along the horizontal member between each scaffold plate, A shielding member comprising an elastic cover body along the short direction and a pair of bent leaf springs suspended from the center of the lower surface of the cover body is provided, and the pair of bent leaf springs in this shielding member are placed on the horizontal member Assume that both ends of the cover body are brought into contact with each scaffold plate while being fitted.
[0009]
In this case, more specifically, the cover body includes an elastic plate formed in a mountain shape and a pair of hook pieces provided at the center of the lower surface of the plate, and the pair of bent leaf springs includes a vertical piece and a vertical piece. A locking piece provided at the upper end of the vertical piece, a curved piece provided continuously at the lower portion of the vertical piece, and a guide piece provided continuously at the lower portion of the curved piece and expanding outwardly, between the pair of vertical pieces. It is preferable that a reinforcing plate is installed, a stop piece is suspended from the central lower surface of the reinforcing plate, and the both are welded while the locking piece is locked to the hooking piece.
[0010]
Similarly, it is preferable that a gap is provided in the middle of the leaf spring to prevent interference with the hook.
