Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a scaffold plate locking tool, and more particularly to a scaffold plate locking tool provided inside a building.
[0002]
[Prior art]
When building a framework of a building using steel, first erected a steel column on the foundation, erected a quadrilateral quadrangular wall frame between them, and installed a floor beam on the second floor above it. In addition, a wall frame on the second floor will be installed on top of it. At this time, if the worker stands on the ground or the foundation, the hand cannot reach the floor beam on the second floor, so it is necessary to provide a scaffold at an intermediate height. It is necessary to provide a scaffold. This scaffold will be provided inside the building.
[0003]
FIG. 1 shows an example of a typical representative scaffold provided inside a building. In FIG. 1, A is a foundation, B is a steel column, and C to E are wall frames. In order to provide a scaffold for such a shaft assembly, the bracket F is fixed at a middle height on one side of the wall frame C, and the bracket G is also fixed between the wall frames D and E. The scaffolding board is put on these brackets. In this way, a bracket is attached in the middle of one wall surface extending in the horizontal direction, a scaffold plate is placed on the bracket, and the scaffold plate is supported by the bracket.
[0004]
However, such a bracket is not used at the end of the scaffold plate. Because the wall frame usually has an intermediate beam H at an intermediate height as seen in the wall frames C to E, it is sufficient to place the end of the scaffolding plate on the intermediate beam H. It is. However, since the width of the middle rail is usually about 60 mm and a wall panel is attached to the outside thereof, the end of the scaffold plate is only supported over a length of 60 mm or less. Therefore, there was a high possibility that the scaffolding plate would come off the middle rail, which was dangerous.
[0005]
[Problems to be solved by the invention]
The present invention has been made in order to eliminate the above-described danger. That is, this invention is intended to provide a locking tool for the purpose of preventing the scaffold plate from falling off the middle rail when the end of the scaffolding plate is placed on the middle rail of the wall frame. It is.
[0006]
[Means for Solving the Problems]
This inventor paid attention to the fact that the scaffold plate has a cavity on the back side. That is, recently, steel plate scaffolding plates are often used, and one end in the longitudinal direction has a structure as shown in FIG. 2 when viewed from the back side, and there is a cavity suitable for locking there. I realized that there was. The structure of the scaffolding plate T will be described with reference to FIG. 2. On the front side, there is a long surface plate P having a flat C-shaped cross section, and inside the opening of the surface plate P is the center in the width direction. A reinforcing plate Q having a mountain-shaped cross section along the longitudinal direction is attached to the position, and a lid-like end plate R is attached to both ends of the front plate P and the reinforcing plate Q to form a scaffold plate T. ing. As a result, a cavity S with four sides surrounded by edges is formed on the back side of the scaffold plate. Then, this inventor came up with utilizing this cavity S for latching of a scaffold board.
[0007]
The present invention relates to a channel member having a U-shaped cross section that is put on an intermediate rail attached to a wall frame, and is a locking piece that stands outward on a central piece of three pieces that are continuous in a U-shape. There is provided a scaffolding plate locking tool characterized in that the locking piece can be inserted into a cavity on the back side of the scaffolding plate.
[0008]
An example of an embodiment of the scaffold plate locking tool according to the present invention will be described with reference to the drawings. FIG. 3 is a perspective view of a scaffold plate locking tool according to the present invention. FIG. 4 is an exploded perspective view illustrating a usage state of the scaffolding plate locking tool illustrated in FIG. 3. FIG. 5 is a perspective view of another scaffold plate locking tool according to the present invention. FIG. 6 is a perspective view of another scaffolding plate anchor according to the present invention. FIG. 7 is a perspective view of still another scaffold plate locking tool according to the present invention.
[0009]
In FIG. 3, the scaffolding plate locking device according to the present invention is attached to a channel member 1 having a U-shaped cross section and a central piece of three pieces that are continuous in a U shape in the channel member 1. The cross section is composed of an L-shaped locking member 2. The channel material 1 has such a size that it can be put on the middle rail H of the wall frames C to E shown in FIG. The locking member 2 is fixed by extending a folding line 21 of L along the longitudinal direction of the channel member 1, and fixing one piece 22 of the two pieces of L in close contact with the central piece of the channel member 1. The one piece is raised on the center piece to form the locking piece 23. What is constituted in this way is the scaffolding plate locking tool X according to the present invention.
[0010]
The scaffolding plate locking tool X shown in FIG. 3 is used as shown in FIG. That is, first, the channel material 1 of the scaffolding plate locking tool X is put on the middle rail H of the wall frame. Then, the scaffolding plate locking tool X can move in the longitudinal direction of the intermediate beam H but cannot move in the width direction of the intermediate beam H, and the locking piece 23 stands upright on the channel material 1. It becomes. Next, when the scaffolding plate T is placed on the scaffolding plate locking tool X, the locking piece 23 enters the cavity S on the back side of the scaffolding plate T, and the scaffolding plate T is in close contact with the locking tool X. Since the end plate R is fixed to the end of the scaffolding plate T, even if the scaffolding plate T is to be detached from the locking tool X, the locking piece 23 collides with the end plate R, and the scaffolding plate T is locked. It will not come off from the ingredient X. Thus, the scaffolding plate T can be prevented from falling off.
[0011]
In FIGS. 3 and 4, an extra locking member 2 having an L-shaped cross section is provided to provide the locking piece 23 on the channel material 1, but this is not always necessary. As shown in FIG. 5, a U-shaped cut is made in a part of the central piece of the channel material 1, and a part surrounded by the cut is raised from the channel material 1 to form the locking piece 23. Good. Further, as shown in FIG. 6, a large cut may be made in the channel material 1 and a part thereof may be raised from the channel material to form the locking piece 23.
[0012]
Further, as shown in FIG. 7, the folded piece 3 or 4 having a cross section of Ω shape can be fixed on the central piece of the channel material 1 and its one surface 23 can be used as a locking piece. Thus, the scaffolding plate locking tool according to the present invention can take various forms.
[0013]
【The invention's effect】
According to this invention, since the scaffolding plate locking device includes the channel material having a U-shaped cross section that covers the middle rail attached to the wall frame, the channel material can be covered on the middle rail. Can be easily attached to the middle rail. In addition, since this scaffolding plate locking tool is provided with a locking piece that stands on the outside of the central piece among the three pieces of the channel material that is continuous in a U-shape, the channel material is used as the middle rail as described above. If it covers and fixes to a wall frame, it will be in the state which the latching piece stands on the middle crosspiece. In addition, since the locking piece can be inserted into the cavity on the back side of the scaffolding plate, when the scaffolding plate is placed on the scaffolding plate locking tool, the locking piece fits into the cavity of the scaffolding plate. . Then, since the end plate is attached to the end of the scaffold plate, the locking piece collides with the end plate and prevents the movement of the scaffold plate, so the end of the scaffold plate cannot be detached from the locking device. Therefore, the scaffold plate is prevented from falling. In this way, the present invention has the effect of preventing the scaffolding from falling off and making building construction safe.
