Abstract

(57) [Summary] [Purpose] Attach the base plate to the base plate easily and securely.
Remove it. [Structure] In a scaffolding floor plate, in which a hook piece 6 that prevents the base plate B from moving in the horizontal and vertical directions is provided on the base plate mounting surface 3 on the upper surface of the floor plate body 1, the base plate B is mounted. A guide portion 2 is provided to prevent horizontal movement during rotation. As a result, the base plate B is placed on the base plate attachment surface 3 and the corner portion C of the base plate B is not moved in the horizontal direction, but is slidably rotated while being slid on the inner surface of the guide portion 2. Lock on the hook piece 6. Further, when removing the base plate B, the corner portion C of the base plate B is rotated while being slid on the inner side surface of the guide portion in the same manner as described above.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scaffolding board for construction work.

[0002]

[Prior Art]

 In conventional scaffolding base plates, hooks that prevent the base plate from moving horizontally and vertically are installed on the base plate mounting surface of the base plate body, which is made of a metal flat plate. There was one with a plurality of hooks that could be engaged and disengaged. Then, the above-mentioned base plate is slid and rotated with respect to the base plate mounting surface to be locked to the hook piece.

[0003]

[Problems to be solved by the device]

 However, at the construction site, workers have to proceed with work quickly, and in the above-mentioned scaffolding base plate, when the base plate is attached to the base plate body, the base plate moves horizontally when rotating and sliding. In some cases, it would be difficult to lock it on the hook piece because it would be displaced. Furthermore, if the base plate is not securely locked to the base plate, it will be the base of the scaffolding, and there is a risk of the scaffolding collapsing due to its instability.

An object of the present invention is to provide a scaffolding base plate that allows the base plate to be easily and surely attached to and removed from the base plate body.

[0005]

[Means for Solving the Problems]

 The present invention relates to a scaffolding base plate in which a hook piece for preventing horizontal and vertical movement of the base plate mounting direction is provided on the base plate mounting surface on the top surface of the base plate body when the base plate is mounted and rotated. The gist is that a guide part is provided to prevent horizontal movement.

[0006]

[Action]

 According to the present invention configured as described above, the base plate is placed on the base mounting surface, and the locked portion of the base plate is not horizontally moved, but is slidable on the inner surface of the guide portion. Move it and lock it securely on the hook. Further, when removing the base plate, the engaged portion of the base plate is slid on the inner surface of the guide portion as described above, and is rotated and removed.

【Example】

 An embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, a rib 2 having an inverted U-shaped cross-section as a guide portion is formed in a circular shape on a rectangular base plate main body 1, and a base plate B is attached to the inner bottom of the rib 2. The plate mounting surface 3 is integrally formed at a position higher than the flange portion 4 on the outside of the rib 2. The inner diameter of the rib 2 is formed to be the same as the diagonal line of the base plate B. Mounting grooves 5 are formed on the upper surface of the rib 2 at four positions where the respective corners C of the base plate B are located, and metal hooks 6 are flush with the upper surface of the rib 2 in the mounting grooves 5. Is welded to. The hook piece 6 is composed of an upper surface pressing piece 6a and a hanging piece 6b, and the upper surface pressing piece 6a is formed in a substantially L shape so as to restrict the vertical movement of the corner portion C of the base plate B. The hanging piece 6b is bent and formed on the taper side of the upper pressing piece 6a so as to restrict the movement of the corner portion C of the base plate B in the horizontal direction. The space surrounded by the rib 2 and the hook piece 6 is used as a storage portion 12 for storing the corner portion C. As shown in FIG. 4, below the hanging piece 6b of the base plate mounting surface 3, there is provided a through hole 7 for draining water from the scaffolding material and for preventing clogging of dust. An insertion hole 8 for inserting a stopper (not shown) for fixing is formed in a circular shape. In order to increase the strength of each portion of the base plate B, large and small protrusions 9 and 10 are formed on the flange portion 4 and the upper surface pressing piece 6a, and a concave portion 11 is formed on the base plate mounting surface 3. A member symbol J in FIG. 5 indicates a jack base integrally attached to the central portion of the base plate B.

Next, in order to attach the base plate B to the base plate main body 1 of the scaffolding base plate constructed in this way, as shown in FIG. 5, each corner portion C of the base plate B is placed between each hook piece 6. Place it on the base plate mounting surface 3 so that it is positioned. Then, the base plate B is rotated counterclockwise, and each corner portion C is slid on the inner surface of the rib 2 to be housed in the housing portion 12 so that the base plate B is fixed on the base plate mounting surface 3. To do. On the contrary, the base plate B can be removed in the reverse order of mounting.

As described above, in the scaffolding base plate of the present embodiment, each corner portion C rotates while being prevented from moving horizontally to the inner side surface of the rib 2, so that the base plate B can be quickly mounted. Can be fixed against. The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the base plate B is rotated counterclockwise, but the hanging piece 6b is attached to the opposite side of the above-described embodiment to rotate clockwise. It may be rotated to.

[Effect of the device]

 As described above in detail, the scaffolding base plate of the present invention has an excellent effect that the base plate can be easily and surely attached to and removed from the base plate body.
