Next, the configuration of the handrail 40 will be described.
The handrail 40 is a handrail for working on the tread board 30.
The handrail 40 includes a handrail main body and a pair of wedge fittings.
The handrail main body is a long member.
The pair of wedge metal fittings are metal fittings that are detachably fixed to the scaffolding column 10 and are fixed to both ends of the long member.

Next, the structure of the firing 50 will be described with reference to the drawings.
FIG. 15 is a plan view of the firing according to the embodiment of the present invention. FIG. 16 is a detailed view of the H portion of the fire stroking according to the embodiment of the present invention.
The fire beating 50 is a structural member that is hung over the handrail 40 that is orthogonal to the temporary scaffolding to increase the rigidity.
The fire-fired 50 is constituted by a fire-fired main body 300 and a pair of mounting brackets 100a.
The main body 300 is a long member used in a horizontal position.
The pair of mounting brackets 100a are bracket members that are respectively mounted on the handrails 40 that are orthogonal to each other.
The main structure of the mounting bracket 100 a is the same as that used for the tread plate 30 except for the stopper 130.
The stopper 130 is a single member that is fixed to the mounting bracket main body.
The stopper 130 may be a part of the firing main body 300.

Next, the configuration of the brace 60 will be described.
The brace 60 is a structural member that is hung over adjacent scaffolding struts 10 in order to increase the rigidity of the temporary scaffolding.
The brace 60 is composed of a brace body and a pair of wedge fittings.
The brace body is a long member used obliquely.
The wedge metal fitting is a member fixed to the scaffolding column 10.
A pair of wedge fittings are fixed to both ends of the brace body.

As described above, the mounting bracket according to the embodiment of the present invention has the following effects due to its configuration.
The mounting bracket main body 110 is provided with a downward U-shaped notch W that forms the lower end opening portion X, and the wedge member 120 that is attached to the mounting bracket main body 110 so as to be movable obliquely up and down is provided on the lower end opening portion X. The wedge member 120 can be moved between a lowest advanced position that at least partially closes and a retracted position that opens the lower end opening X, and the wedge member 120 is not lowered below a predetermined position by the stopper 130 in a state of being removed from the horizontal member. In this manner, since the advance position is above the predetermined position, the mounting body can be attached to the horizontal member to connect the member main body and the horizontal member.
In addition, the mounting bracket body 110 is provided with a downward U-shaped cutout portion W that forms the lower end opening portion X, and the wedge member 120 that is attached to the mounting bracket body 110 so as to be movable obliquely up and down includes a lower end opening portion. The wedge member 120 can be moved between an advancing position that closes at least a part of X and a retracted position that opens the lower end opening portion X, and the wedge member 120 is not lowered below a predetermined position by the stopper 130 when removed from the horizontal member. In this case, when the mounting bracket main body 110 is brought close to the horizontal member, the wedge member 120 is pushed by the horizontal member and relatively moved upward, and when the notch W is fitted to the horizontal member, the wedge member 120 falls downward due to gravity. Since at least a part of the lower end opening portion X is closed, the mounting body can be attached to the horizontal member to connect the member main body and the horizontal member.
In addition, when the wedge member located at the advanced position is pushed downward with the notch W fitting on the outside of the horizontal member from above, the mounting bracket main body 110 and the wedge member 120 sandwich the horizontal member. Therefore, the mounting location where the mounting bracket is mounted on the horizontal member is difficult to slip.
In addition, the wedge member is held stably when the wedge member is rotated in the retracted position and the upper part is moved closer to the upper part of the wedge member mounting piece, so that the mounting bracket can be easily removed from the horizontal member. I can do it.
Further, in a state where the wedge member main body protruding portion 122 hits the wedge member mounting piece 112, the wedge member 120 rotates around the position of the bent portion R of the wedge member mounting piece 112 so that the wedge member 120 is stably held. The mounting bracket can be easily removed from the horizontal member.
In addition, the wedge member mounting piece attached to the side surface of the mounting bracket main body piece provided with the notch W forms at least a part of the contour of the wedge member mounting hole through which the wedge member passes, and the surface is tilted up and down when viewed from the side. It is a plate material in which a bent portion that is bent obliquely upward in the middle toward the direction is formed, and the wedge member 120 is rotated in a direction in which the lower end portion coincides with the position of the bent portion R and the upper portion is brought closer to the upper portion of the wedge member mounting piece. Sometimes, the wedge member is stably held, so that the mounting bracket can be easily removed from the horizontal member.

As described above, the constituent members of the temporary scaffold according to the embodiment of the present invention have the following effects depending on the configuration.
The mounting bracket main body is provided with a downward U-shaped notch that forms the lower end opening, and a wedge member that is attached to the mounting bracket main body so as to be movable obliquely up and down closes at least a part of the lower end opening. The advancing position can be moved between a lowermost advance position and a retracted position that opens the lower end opening, and the wedge member is not lowered below a predetermined position by a stopper in a state where it is removed from the horizontal member, and the advance position is the predetermined position. Since it is located above the position, one component member to which the mounting bracket is fixed can be easily attached to another component member having a horizontal member in part.
In addition, the mounting bracket body is provided with a downward U-shaped notch that forms a lower end opening portion, and a wedge member that is attached to the mounting bracket body so as to be movable in a slanting vertical direction has at least a part of the lower end opening portion. It can move between the advanced position where it closes and the retracted position where the lower end open part is opened, and when it is removed from the horizontal material, the stopper does not fall below the predetermined position by the stopper, and the mounting bracket body is made horizontal material. When approaching, the wedge member is pushed by the horizontal member and relatively moved upward, and when the notch is fitted to the horizontal member, the wedge part falls downward due to gravity and closes at least a part of the lower end opening part. Therefore, one component member to which the mounting bracket is fixed can be easily attached to another component member having a part of the horizontal member.
In addition, the mounting bracket body is fixed to a structure that forms part or all of the frame of the temporary scaffolding tread, and the structural material to which the mounting bracket body is fixed also serves as a stopper. Thus, the temporary scaffolding tread can be easily attached to the temporary scaffolding bracket.
In addition, when the wedge member positioned at the advanced position is pushed downward with the notch W fitting on the outer side of the horizontal member from above, the mounting bracket body and the wedge member sandwich the horizontal member. One component member for fixing the mounting bracket can be attached to another component member without slipping.
In addition, the wedge member is held stably when the wedge member is rotated in the retracted position and the upper part is moved closer to the upper part of the wedge member mounting piece, so that the mounting bracket can be easily removed from the horizontal member. I can do it.
In addition, the wedge member mounting piece attached to the side surface of the mounting bracket main body piece provided with the notch W forms at least a part of the contour of the wedge member mounting hole through which the wedge member passes, and the surface is tilted up and down when viewed from the side. It is a plate material in which a bent portion that is bent obliquely upward in the middle toward the direction is formed, and the wedge member 120 is rotated in a direction in which the lower end portion coincides with the position of the bent portion R and the upper portion is brought closer to the upper portion of the wedge member mounting piece. Sometimes, the wedge member is stably held, so that the mounting bracket can be easily removed from the horizontal member.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
In the description of the tread, it has been described that the tread plate mounting bracket 100 includes a pair of mounting brackets 100a and a pair of mounting brackets 100b. However, the present invention is not limited to this. For example, the mounting bracket 100a may be provided instead of the mounting bracket 100b.
