Description

The present invention relates to a scaffolding auxiliary member mounting bracket used for assembling a temporary assembly scaffold placed on the side surface of a building at a construction site or the like during construction. Here, the scaffold auxiliary material means, for example, a handrail, a brace, and the like.

Conventionally, when constructing a temporary scaffold around a building, two pipe columns are arranged at a predetermined interval, connected by a horizontal bracket, and a scaffold plate or a staircase is attached between adjacent horizontal brackets. However, when a temporary scaffolding is to be constructed between adjacent buildings or the like, there are cases where the two columns cannot be installed with a gap between them at a predetermined interval. In such a case, for example, as described in Patent Document 1, one pipe strut is erected at a predetermined interval, and a horizontal bracket is attached in a cantilevered state to a predetermined height position of these pipe struts. The scaffolding board is hung between the matching horizontal brackets. In addition, at the predetermined height position of this pipe column, there are usually four column-side connection brackets with a U-shaped cross section around the column, and the column side connection bracket and the pipe are provided. A wedge fitting provided on the horizontal bracket can be attached to the wedge space formed by the support column.
However, in a horizontal bracket in a cantilever state, it is necessary to erect the pipe struts while being biased to one of the narrow places, and there are cases where it is difficult to arrange such pipe struts due to obstacles. Therefore, if the scaffolding plate is attached to the column-side bracket of the pipe column so that it spreads on both sides of the pipe column, that is, if the wedge bracket is arranged in the center of the width direction of the scaffolding plate, the pipe column is placed in the gap (narrow place). Can stand in the center. And since workability | operativity is bad only with a scaffold board, attaching a handrail etc. is also performed using the other support | pillar side connection metal fitting provided in the pipe support | pillar.

However, in the conventional scaffold structure, there is a problem that it is weak against a lateral load because it is connected vertically and horizontally only by a vertical member made of pipe struts and a cross member made of a scaffold plate connecting the pipe struts. . Therefore, in order to increase the strength of the temporary scaffold as a whole, it is preferable to add braces, but in the conventional scaffold auxiliary material mounting bracket, such mounting means is not provided, and it is not possible to attach reinforcing materials such as braces. It was difficult.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a scaffold auxiliary material mounting bracket capable of easily mounting a member (for example, a brace) for reinforcing a temporary scaffold.

The scaffolding auxiliary material mounting bracket according to the first device for the purpose is a scaffolding auxiliary material mounting bracket used for a temporary scaffold,
A vertical pipe material having an outer diameter in the range of 40 to 50 mm;
It is attached to one of the vertical pipe members via a horizontal connecting member, and is attached to a column-side wedge space formed by a column-side connecting bracket having a U-shaped cross section provided on the side of an upright pipe column. Possible wedge fittings,
The horizontal connecting member is mounted with the horizontal connecting member at the same height as the horizontal connecting member on the outer side of the 90 degree position and the 270 degree position of the vertical pipe member in plan view with reference to the attachment center position of the horizontal connecting member (that is, 0 degree position). A first and second connecting fittings having a U-shaped cross section forming the first and second wedge spaces;
A third connecting fitting provided on the outside of the vertical pipe member at a position of 180 degrees with respect to the mounting center position of the horizontal connecting member, and having a U-shaped cross section that forms a third wedge space.

Although the length of the horizontal connecting member is arbitrary, it is preferably about ¼ to ½ of the width of the scaffold plate attached to the column-side connecting bracket of the pipe column. For example, handrail leg metal fittings are attached to the first and second wedge space portions, and brace end fittings are attached to the third wedge space portion, for example. Thereby, the temporary scaffold can be reinforced.

A scaffolding auxiliary material mounting bracket according to a second aspect of the present invention is the scaffolding auxiliary material mounting bracket according to the first aspect of the present invention, wherein the third coupling bracket is located above the first and second coupling brackets. This facilitates the attachment of the first to third connection fittings, specifically welding.
A scaffolding auxiliary material mounting bracket according to a third aspect of the present invention is the scaffolding auxiliary material mounting bracket according to the first and second aspects of the present invention, wherein the horizontal connecting material is a pipe.
A scaffolding auxiliary material mounting bracket according to a fourth aspect of the present invention is the scaffolding auxiliary material mounting bracket according to any of the first to third aspects, wherein the horizontal coupling member is partially fitted and fixed to the upper portion of the wedge metallurgy. The connecting portion has a wedge portion which is reduced in width at the lower portion of the connecting portion and is fitted into the support-side wedge space portion.
Here, it is preferable that the brace end fitting is parallel to the vertical pipe member in an upright state with respect to the brace body arranged obliquely. Then, a stopper for preventing removal may be provided for the brace end fittings attached to the third connecting fitting.

And the scaffolding auxiliary material mounting bracket according to the fifth invention is the scaffolding auxiliary material mounting bracket according to the first to fourth inventions, wherein the length of the vertical pipe material is one of the outer diameter of the vertical pipe material. It is in the range of 6 to 5 times.

A third fitting with a U-shaped cross-section that is provided outside the vertical pipe member at a position of 180 degrees with respect to the mounting center position of the horizontal connecting member and that forms a third wedge space. For example, a reinforcing member such as a brace is attached to the third wedge space. You can kick it. Thereby, the strength of the temporary scaffold using this scaffolding auxiliary material mounting bracket can be increased.
Furthermore, since the vertical pipe member is attached via the horizontal connecting member, the position of the first to third wedge space portions can be moved away from the position of the pipe strut of the temporary scaffold, for example, the first, The handrail to be attached to the second wedge space and the brace position to be attached to the third space can be arranged on the end side in the width direction of the scaffold plate to be attached to the pipe column, thereby improving workability.

In particular, in the scaffolding auxiliary member mounting bracket according to claim 2, since the third coupling bracket is located above the first and second coupling brackets, the first to third couplings are independent of the vertical pipe member. A bracket can be attached.

In the scaffolding auxiliary member mounting bracket according to the third aspect, since the horizontal connecting member is made of a pipe, it is inexpensive and can give sufficient and uniform strength in any direction with respect to the axis of the pipe.

5.
