Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an assembled scaffolding unit, and more particularly, to a stackable and assembled scaffolding unit used at a construction site or the like.

[0002]

[Prior Art]

 Prefabricated scaffolds are frequently used in the construction and repair of relatively low-rise buildings and houses. Traditionally, wooden scaffolds have been widely used, but in recent years, assembled scaffolding units using pipe-shaped metal units have become popular. This assembly scaffolding unit is preferable because standardized members can be easily assembled in the field and can be easily disassembled and put away after use. Conventionally, as a structure of a publicly known assembled scaffolding unit, usually, two scaffolding units are assembled by facing two unit members in which two columns are connected by a connecting beam and facing each other. It is common.

However, in the case of the conventional scaffolding unit, as shown in FIG. 4, since the position of the joint beam 15 connecting the two support columns 11 and 11 is near the top of the support column 11, as a result, it goes without saying. The position of the scaffold is also above the pillar. Therefore, in addition to lack of stability, when stacking the scaffolding units to perform work on the uppermost scaffolding unit, the safety of the worker becomes a problem. Therefore, there are times when it is necessary to use a safety belt for workers working at high places, and the safety belt must be fixed at a height above the waist of the worker. Safety bands cannot be attached to conventional assembly scaffolding units. If there are braces or handrails between the two unit members, it is possible to attach a safety belt to them, but with the conventional ones, the position is below the waist of the worker. In order to ensure the safety of workers, generally, a safety belt is not attached at a position lower than the waist height.

[0004]

[Problems to be solved by the device]

 It is an object of the present invention to provide a prefabricated scaffolding unit having excellent safety and stability, which allows a safety belt to be attached to a position higher than the waist even on the uppermost scaffold.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the inventors of the present invention have earnestly studied and, as a result, have determined that the position of the connecting beam that connects the columns is near the center of the entire column length, and that the scaffolding unit is assembled from the scaffold to the column top. By configuring the length to be equal to or higher than the waist of the worker, the worker can use the safety belt at any time, the weight balance of the unit members is good, and the carrying is easy. We found that and completed the present invention.

That is, the gist of the present invention is to make two unit members in which two stackable stanchions having an insertion joint at the top and a joint receiving portion at the bottom are connected by a joint beam, face each other, and between the respective joint beams. In an assembled scaffolding unit that bridges scaffolding members to form a scaffold, the connecting position of the joint beam is within the range of 40 to 60% of the total length of the strut, and the length from the scaffold to the top of the strut is 80 cm or more. It exists in the characteristic scaffolding unit.

[0007]

【Example】

 A preferred embodiment of the present invention will be described below with reference to the drawings. 1 is a side view showing an embodiment of the assembled scaffolding unit of the present invention, and FIG. 2 is a perspective view of the same. Usually, it is made of a metallic pipe-like material, 1 is a column, 2 is an insertion joint, 3 is a brace pin for fixing braces, and 4 is a reinforcing member. A joint receiving portion is formed at the lower end of the column 1. Two such columns are opposed to each other and connected by a connecting beam 5. The position of the joint beam 5 is 40 to 60% of the total length of the supporting column, and is 80 cm or more, preferably 90 to 120 cm below the top of the supporting column. Two such unit members are made to face each other, and a scaffolding member 6 made of a metal plate or mesh is spanned and fixed to each joint beam 5, and a scaffold is assembled as shown in a perspective view in FIG. Reference numeral 7 is a brace, and hooks (not shown) at both ends are hooked on the brace pin 3 to fix the main body. Reference numeral 8 is a horizontal joint that is stretched near the top of the column, and is used to fix the main body and to attach a handrail to the handrail. FIG. 3 is a perspective view when two of the above-mentioned assembled scaffolds are inserted and stacked through the joint 2.

[0008]

[Effect of the device]

 Since the assembled scaffolding unit of the present invention is constructed as described above, the scaffolding position of the main body is low, which is not only stable and easy to work, but also the length from the scaffolding to the top of the column is the waist of the worker. Since it is more than the height of the safety belt, if the end of the safety belt is attached to the horizontal joint (handrail) stretched near the top of the pillar, it will be supported at a position higher than the waist, ensuring the safety of the operator. be able to. Further, in the case of the assembled scaffolding unit of the present invention, since the position of the scaffold member is low, the work for assembling the unit member can be performed at a low position, so that the workability is also good.
