Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a suspended scaffold, and particularly to a chain-suspended type of suspended scaffold used for high-altitude work near the ceiling.

[Background of the idea]

A conventional chain-suspended suspension scaffold is composed of a plurality of chains or wire ropes suspended from locking devices fixed in advance to the ceiling, etc., and a work floor attached to the chains or the wire ropes. has been done. Conventionally, when locking the work floor to the wire rope or the chain,
This is done by wrapping cloth material around a wire rope, or by securing a chain to the work floor.

[Problem that the invention attempts to solve]

However, in this method of locking the work floor, the installation work is time-consuming, and there is a problem in that the locking position of each chain has a difference in height.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a suspended scaffold that allows easy attachment of chains on a work floor and adjustment of the height.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a suspended scaffold in which a work floor is suspended from a plurality of chains suspended from a ceiling or the like at arbitrary height positions via a locking member. The locking member includes a corner plate fixed to a corner portion of the work floor, and a locking piece formed protruding from the corner plate and inserted through a ring material forming the chain.
It is characterized by comprising a retaining metal fitting that is attached to the locking piece and prevents the locking piece from coming off from the chain.

[Effect]

According to the suspended scaffolding according to the present invention, the work floor can be easily installed at an adjusted height by simply fitting the locking piece of the locking member into the ring material of the chain, and the work floor can be installed at an easily adjusted height. Since a retaining metal fitting is attached to the locking piece, the chain can be reliably locked to the work floor.

〔Example〕

Hereinafter, preferred embodiments of the suspended scaffolding according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a suspended scaffold according to an embodiment of the present invention, in which four fasteners 14, 14, 14, 14 are fixed in advance at predetermined positions on a ceiling or the like. Furthermore, a chain 10 is suspended from each of the locking tools 14. Also, chain 10, 10, 10, 1
0, a work floor 16 is attached at a predetermined height position via a locking member to be described later at a corner portion of the work floor 16. Further, the work floor 16 is formed into a frame by frame members 18, 18, 18, 18, and between each frame member 18 there are scaffolding boards 20,
20... are constructed and constructed.

FIGS. 2 and 3 show details of the corner portion of the work floor 16 where the locking member is provided. Further, the locking members include the corner plate 22, the locking piece 34,
It is composed of a hook bolt 44 as a retaining fitting.

The frame members 18 are connected at the corner portions by corner plates 22, and the corner plates 22 are bent into a chevron shape. Frame member 18 is fixed to corner plate 22 with bolts 30 and screws 32. Scaffolding boards 20 at the corners of the work floor 16 are formed with notches, and the chains 10 shown in FIG. 1 are inserted into the notches 21, respectively.

Two locking pieces 34, 34 are provided on the center surface 22A of the corner plate 22, projecting into the notch 21 and spaced apart from each other by a predetermined distance. Figure 4a
As shown in c to c, the locking pieces 34, 34 are inserted into the ring members 40, 40 that constitute the chain 10. As a result, the chain 10 is locked by the locking piece 34, and the height of the work floor 16 is changed by inserting the locking piece 34 through the ring material 40 of the chain 10 at a predetermined height. It is now possible to do so. Further, a recess 42 is formed on the distal end surface of the locking piece 34, and the distal end portions 44A, 44A of the hook bolt 44, which is bifurcated as a retaining metal fitting, are formed.
are fitted. The threaded portion 46 of the hook bolt 44 is inserted into the opening 47 in the center surface 22A of the corner plate 22, and is fixed by tightening the wing nut 48. The chain 10 is prevented from being removed from the locking piece 34 by the bolt 44.

To explain the operation of the suspended scaffold according to this embodiment configured as described above, the ceiling anchors 14, 14,
14, 14, chain 10, 10, 10, 10
hang. Next, each chain 10 is provided with a plurality of work floors 16, 16, .

In this case, the work floor 16 is connected to the corner plate 22
The chain 10 can be easily locked by simply inserting the locking piece 34 into the ring material 40 of the chain 10. Also, locking piece 3
The tips 44A, 44A of the hook bolts 44 are fitted into the recesses 42 on the tip surface of the chain 10 and fixed by tightening with the wing nuts 48.
is prevented from coming off and the work floor 16 is securely locked. When changing the height of the work floor 16, the height can be easily adjusted by selecting a ring material 40 of a predetermined height of the chain 10. Furthermore, since the chain 10 is inserted into the notch 21 at the corner of the work floor 16, and the locking piece 34 is provided in a protruding manner within the notch 21, it will not interfere with the installation of another work floor 16 provided adjacently. do not become.

FIG. 5 is a perspective view showing a modification of the retaining fitting used in the hanging scaffold according to the present invention. Second
In the hook bolt 44 shown in the figures to FIG.
The locking fitting 50 shown in FIG.
, the base end is rotatably attached to the central surface 22A of the corner plate 22 via a pivot pin 54, and the distal ends 52A, 52A are attached to the locking pieces 34,
The pin 5 is inserted through the opening formed on the side of the pin 5.
Pinned by 6. In such a configuration, the retaining fitting 50 can reliably prevent the chain 10 from coming off.

[Effect of idea]

As explained above, according to the suspended scaffold according to the present invention, a locking piece that is inserted into the ring material of the chain is provided protrudingly on the corner plate as a locking member, and a locking piece is provided on this locking piece to prevent it from slipping out. Equipped with fasteners, the work floor can be easily installed.
The height can be adjusted.
