Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a scaffold bracket used for a scaffold at a construction site such as a general house.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional scaffolding bracket 6A has an arm portion 62 projecting from a clamp 61 in one direction.
The clamp 62 is attached to the building 65 of the scaffold by tightening the tightening nut 64 screwed into.

[0003] However, as shown in the figure, if the width of the assembling location of the scaffold 65 is narrow, the clamp 61 comes close to the wall surface 6B of the building, so that the wall surface 6B hinders the tightening work of the clamp 62. However, there has been a problem that the mounting work of the bracket becomes very troublesome. Also,
As shown in FIG. 7, when the building 66 of the scaffold 65 is not vertically erected and is slightly inclined, the scaffold bracket 6A
Is slightly inclined, and the inclination angles of the adjacent brackets 6A for scaffolds vary. Therefore, when the scaffolding plate is installed between the brackets 6A for scaffolding, the scaffolding plate rattles and work at a high place becomes very difficult. It was dangerous. On the other hand,
Japanese Patent Publication No. Hei 2-14600 and Japanese Utility Model Publication No. 52-34814
As described in the report.
Scaffolding brackets have been proposed, but scaffolding 65
Attachment of scaffold bracket is far from wall 6B
Work will still be easier,
As mentioned, if the building is near the wall of the building,
Conventional scaffolding brackets that interfere with the walls of objects
But the installation work of the scaffold bracket is said to be troublesome
The problem could not be solved. In addition,
As described in JP 14600
Scaffolding brackets with horizontal rods
It has been proposed that such scaffolding brackets can be used on building walls
Clamp tightening work away from the surface
Can be easily installed on the scaffolding bracket.
However, it is not possible to eliminate rattling of the scaffold
Was.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned points, and the purpose of the invention is to make it easy to attach to a building even in a narrow place. Another object of the present invention is to provide a scaffold bracket capable of correcting the inclination angle of the arm portion to the same degree by applying a load to the scaffold plate and eliminating rattling of the scaffold plate.

[0005]

A scaffold bracket according to claim 1 proposed to achieve the above object is a scaffold bracket attached to a scaffold for installing a scaffold plate, wherein the scaffold bracket is attached to a building site of the scaffold. projecting the short arms and long arms from the mounting portion in opposite directions for, these two
The combined length of the arms is approximately the same as the width of the scaffold
As well as the mounting work with this short arm.
It is characterized in that it is configured to secure a business space .

According to a second aspect of the present invention, there is provided the scaffolding bracket according to the first aspect, wherein the mounting portion is constituted by a holding portion such as a clamp.

[0007]

According to the scaffolding bracket of the present invention, in a scaffolding bracket attached to a scaffold for installing a scaffolding plate, two arms are respectively protruded in opposite directions from a mounting portion for attaching the scaffolding. The length of one arm is longer than the length of the other arm, so the mounting part can be separated from the wall of the building by the length of the arm, and can be attached to the building. Work becomes easier.

In the case where a person is placed on a scaffold plate provided on the bracket, as shown in FIG. 2, the length of the long arm is longer than that of the short arm, so that the scaffold on the long arm side is used. More load is applied to the plate, and as a result, the scaffold plate is uniformly inclined to the long arm side. As a result, even if the scaffold bracket is attached with a slight inclination, the scaffold plate rattles. Can be eliminated, and stable work can be performed at a high place.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the scaffold structure of the present invention will be described below with reference to the drawings. The scaffolding bracket A is, as shown in FIG.
The arms 2 and 2A of the book are provided so as to project in opposite directions, and the length of one arm 2 is configured to be longer than the length of the other arm 2A.

The mounting portion 1 has a holding structure like a clamp, and is configured to be fixed to the building B by tightening a nut 12 screwed to the screw portion 11. Screw holes 3 and 3A are formed in the distal end portions of the long arm portion 2 and the short arm portion 2A. Oblique material 3 from long arm 2
Is extended, and an engagement portion 4 is attached to a lower end of the diagonal member 3.

A1 is a preliminary mounting portion, and the preliminary mounting portion main body A11 has a holding structure like a clamp, and is fixed to the building B by tightening a nut A14 screwed to the screw portion A13. It is configured to: A threaded rod A12 protrudes from an outer peripheral portion of the preliminary mounting portion main body A11.

FIG. 3 shows a state in which the scaffolding bracket A is attached to the one-side building B of the scaffold.
The arm portions 2 and 2A protrude horizontally from the building B while being fixed to the building B. The engaging portion 4 of the long arm portion 2 is engaged with the building B.
As is clear from this figure, the mounting portion 1 can be separated from the wall C of the building by the length of the short arm portion 2A.
The work of tightening the nut 12 of the mounting portion 1 can be easily performed without being disturbed by the wall surface C.

FIG. 2 shows a scaffold plate 2 between scaffold brackets A.
Is shown, and the engaging hook D1 of the scaffold plate D is engaged with the arm portions 2 and 2A. Then, as shown in the figure, when the worker is placed on the scaffold D, the short arm 2A
Elongate have different partial lengths of the arms 2, create the long arm portion 2 and
When the center of gravity of the trader moves and an eccentric load acts on the building, the building B
Can be evenly and equally inclined to the long arm 2 side, and as a result, a gap can be eliminated between the engaging hook D1 of the scaffold plate D and the scaffold bracket A.

FIG. 5 shows an application example in which the scaffolding bracket A is used as a brace. An auxiliary mounting portion A1 attached to the scaffolding bracket A holds another building B1.

[0015]

As is clear from the above description, according to the scaffolding bracket of the present invention, the mounting portion can be separated from the wall of the building by the length of the arm portion, and the screws for the mounting portion can be tightened. Is not disturbed by the building, so that the mounting work in a narrow place becomes easy.

When a person is placed on the scaffold , the center of gravity of the worker is placed on the scaffold on the longer arm side than on the scaffold on the shorter arm.
Eccentric load that tilts the long arm downward.
By using the scaffolding bracket , the scaffolding bracket can be tilted uniformly and equally to the long arm side, and as a result, the scaffolding of the scaffolding plate can be eliminated and stable work at high places can be achieved. Can be secured.
