[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a scaffold plate used in a construction site or the like.

[0002]

2. Description of the Related Art Conventionally, for example, it is difficult to manufacture a scaffold made of aluminum having a width of about 800 mm. Therefore, when a scaffold having a large width is required, as shown in FIG. (51) was used side by side.

[0003]

However, when a plurality of narrow scaffolds (51) are arranged and used as a wide one (52), it is necessary to prevent each scaffold (51) from shifting laterally. In addition, it is necessary to connect the scaffolding plates (51) with bolts or the like, and therefore, there is a problem that this connecting work requires a great deal of labor.

An object of the present invention is to address the above-mentioned problems of the prior art.
Resolved, the scaffolding plates are easily connected to provide a connection structure of the scaffold board can moreover be freely folded.

[0005]

Means for Solving the Problems To achieve the above object,
For this purpose, the present invention relates to a connecting structure of a scaffold plate for connecting adjacent scaffold plates via a connecting member, wherein the connecting member has a horizontal wall portion and a transverse cross-section that curves upward from both edges of the horizontal wall portion. The sliding wall portion has a circular arc shape and a folded wall portion provided in a folded shape from the upper end of the sliding wall portion. A groove portion is formed by the sliding wall portion having a circular cross section and the folded wall portion. A downward recess is provided on the lower surface of the connection edge of the field plate, and an engagement wall that protrudes toward the opening side of the recess and that can be fitted into the groove of the connection member is provided at the lower end of the connection edge side wall of the downward recess. When provided Ru

[0006]

According to the scaffold plate connecting structure of the present invention having the above-described structure, the two scaffold plates are connected in parallel only by fitting the engaging walls of the adjacent scaffold plates into the grooves at both edges of the connecting member. be able to.

[0007] By rotating one of the adjacent scaffold plates downward, the guide surface portion having an arc-shaped cross section in the downward recess of the scaffold plate is connected to the scaffold plate of the connecting member. The center of the folded wall portion on the same side as the center, slide the sliding wall portion of the cross-section circular arc on the same side of the connecting member, the folded wall of the connecting member on the contact surface of the downward recess of the scaffold plate As a result of the contact of the parts, the scaffolding plate on one side is turned by approximately 90 ° with respect to the scaffolding plate on the other side.

Next, the sliding wall on the other side of the connecting member is slid on the guide surface in the downward recess of the scaffold plate on the same side around the tip of the folded wall on the same side. Thereby, the connecting member itself rotates by 90 °, and the one-side scaffold plate further rotates by 90 ° integrally with the connecting member. As a result, the one-side scaffold plate finally rotates by 180 °, It will overlap with the lower surface of the adjacent scaffold plate on the other side, and the connecting member will
The scaffolds are folded so as to be inside the two scaffolds , and the two scaffolds can be folded in two.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 4, adjacent scaffold plates
(1) A connecting structure of a scaffolding plate for connecting the two members via a connecting member (3), wherein the connecting member (3) includes a horizontal wall (4) and both edges of the horizontal wall (4). Sliding wall portions (5a) and (5b) having an arc-shaped cross section curved upward from the portion and folded wall portions (6a) and (6b) provided in a folded shape from the upper ends of the sliding wall portions (5a) and (5b). Consisting of
Sliding walls (5a) (5b) and folded walls (6a) (6
The grooves (7a) and (7b) are constituted by b), and both scaffold plates (1)
Downward recesses (8a) and (8b) are provided on the lower surface of the connection edge of (2), and downward recesses are provided at the lower ends of the connection edge side walls (9a) and (9b) of the downward recesses (8a) and (8b). (8a) (8b)
Engagement walls (10a) (10b) that can be fitted into the grooves (7a) (7b) of (3) are provided, and the side surfaces of the connection edges in the downward recesses (8a) (8b) are connected to the connection member (3). ) Is formed as a contact surface (15a) (15b) with which the folded wall portion (6a) (6b) abuts, and the downward recess (8a) (8a) ( A guide surface (16a) (16b) having an arc-shaped cross section is formed over the ceiling surface of 8b), and a sliding wall portion (5a) (5b) having an arc-shaped cross section at both edges of the connecting member (3). Recesses (8a) in both scaffolding boards (1) and (2) to be connected
The guide surfaces (16a) and (16b) having a circular arc cross section in (8b) can be slid.

In this embodiment, the scaffolds (1) and (2) and the connecting member (3) are made of extruded aluminum.

The downward recesses (8a) (8) of the adjacent scaffolding boards (1) and (2)
b) and the lower surface of the edge opposite to the connecting edge of each scaffold plate (1), (2) are provided with grounding portions (1
1) is provided, and a rubber non-slip member (13) is fitted into a lip groove (12) formed at the center of the lower surface of the ground part (11).

In the figures, (14a) and (14b) are both scaffold plates (1) and (2).
5 shows a protruding wall horizontally protruding from the upper part of the connection edge side wall (9a) (9b) of FIG.

According to the connecting structure of the scaffold plate of the above example, the scaffold plate adjacent to the grooves (7a) and (7b) at both edges of the connecting member (3).
By merely fitting the engagement walls (10a) and (10b) of (1) and (2), the two scaffold plates (1) and (2) can be connected in parallel (see FIG. 2).
