"Temporary enclosures are installed to isolate the construction site from the outside, prevent theft, protect passers-by, and protect adjacent objects" (Non-Patent Document 1). This type of temporary enclosure generally includes a single-tube scaffolding base frame in which a single-tube pipe is assembled by a clamp member for temporary construction, a frame scaffolding base frame in which a building frame and a tread, etc. are assembled. It has a structure in which a temporary enclosure panel such as a universal steel plate or a safety steel plate is fixed (Patent Document 1).

The temporary enclosure panel consists of vertically long metal panels with a width of 50 to 60 cm and a height of about 2 to 3 m, along the road boundary of the construction site, the adjacent land boundary, etc. (hereinafter referred to as "site boundary"). It is supported by a large number of columns and the like arranged. For example, a temporary enclosure in the form of constructing a foundation frame with single-tube scaffolding specifications is for temporary construction such as free clamps for pipe materials such as building ground single pipes, rooted single pipes, reserve single pipes, cross-flow single pipes and single pipe piles. The base frame for temporary enclosure is built on the ground surface by integrally assembling with the clamp member, and the fabric single pipe is fastened or tightened to the construction single pipe with the clamp member, and the temporary enclosure panel is hooked.

Architectural Institute of Japan, Standard Specifications for Building Construction, Explanation JASS2 Temporary Construction 4.1 "Temporary Enclosure"

However, since the conventional temporary enclosure structure has a structure in which the single cloth pipe is fastened or tightened to the single cloth pipe or the building frame column by a clamp member, the single cloth pipe is manually positioned relatively strictly and its horizontal position. It is necessary to ensure the property, and for this reason, a relatively complicated pipe material assembling work is required in the process of constructing the base frame for temporary enclosure.

On the other hand, as described in Patent Document 2, according to the temporary enclosure structure in which the upper and lower rail members are erected between the wedge-coupled columns to support the temporary enclosure panel, the temporary enclosure installation work using the clamp member is performed. It may be possible to solve the problem. However, since the temporary enclosure structure described in Patent Document 2 has a structure in which the load of the temporary enclosure panel is supported by the rail member, a wedge connection dedicated to the temporary enclosure provided with the support structure of the rail member at the end of the column. A type strut and a rail member dedicated to a temporary enclosure that can be supported by this strut must be manufactured or manufactured in advance. Further, since the position of the temporary enclosure panel is defined by the rail member, complicated work for relatively strictly controlling the position and horizontality of the rail member is additionally required. Therefore, the temporary enclosure is installed. The work is considered to be difficult in reality.

In order to solve the problem of complicated pipe material assembly work in the temporary enclosure using the base frame of the single-tube scaffolding specification and the frame scaffolding specification, the present inventors have adopted the base frame of the wedge-coupled scaffolding specification and temporarily A temporary enclosure structure that does not require a special rail member or the like dedicated to the enclosure is proposed in the specification / drawing of Japanese Patent Application No. 2017-186147. The temporary enclosure structure proposed in Japanese Patent Application No. 2017-186147 has an advantage in eliminating complicated pipe material assembly work, and has achieved the intended purpose. For example, the most wedge-coupled strut. When using a base plate (bed plate or floor angle) at the bottom, keep a certain distance from the support to prevent the base plate from protruding from the boundary of the outer wall surface of the temporary enclosure toward the outside (outside the site of the construction site). It was found in the practical application test of the temporary enclosure structure of Japanese Patent Application No. 2017-186147 that it may be desirable to position the outer wall surface of the temporary enclosure panel at the above position, and even in such a situation, as desired. It became necessary to develop an adaptable temporary enclosure panel mooring or underframe.

The present invention has been made in view of such circumstances, and an object of the present invention is to eliminate the disadvantage of the temporary enclosure installation work using a clamp member, a rail member, or the like, and to form a base frame. It is an object of the present invention to provide a temporary enclosure capable of setting a horizontal separation distance between a wedge-coupled support column and an outer wall surface of a temporary enclosure panel to an appropriate dimension, and a method for constructing the temporary enclosure.

In order to achieve the above object, the present invention integrally assembles the columns and the horizontal member to construct a base frame for the temporary enclosure, and the temporary enclosure panel is fastened to the horizontal member by a mooring tool. In a temporary enclosure with a tight structure

The horizontal member provides a temporary enclosure characterized in that it is integrally connected to the support column via the attachment.

According to the temporary enclosure having the above configuration, it is not necessary to fasten or tighten the fabric single pipe to the building ground pipe or the building frame support by the clamp member, so the fabric single pipe is manually positioned and its horizontality is confirmed. Since the work to be performed can be omitted and the number of clamp members used for temporary construction can be greatly reduced, the work of assembling the pipe material in the process of constructing the base frame for temporary enclosure can be simplified or the workability thereof can be improved. Can be improved. Further, according to the temporary enclosure having the above configuration, it is not necessary to manufacture or manufacture a special rail member or the like dedicated to the temporary enclosure in advance, so that a general-purpose wedge-coupled scaffolding member is used as it is as the base frame of the temporary enclosure. Therefore, it is possible to simplify the work of assembling or assembling the base frame of the temporary enclosure. Further, according to the temporary enclosure having the above configuration, a spacer is inserted between the horizontal member and the rib-shaped edge, or an eccentric attachment is inserted between the horizontal member and the support column. Therefore, by setting the member dimensions or the dimensions of each part of the spacer or eccentric attachment to appropriate dimensions, the horizontal separation distance (L) between the central axis of the column and the outer wall surface of the temporary enclosure panel, or equivalent to this. The dimensions to be used (L-1 / 2 x D2, LR, T1 + D1 / 2 + K) can be set to appropriate dimensions.

In addition, according to the temporary enclosure having the above configuration, the height position and the number of horizontal members are temporarily changed according to the height position or the number of installations of the wedge-coupled engaging portion of the support column. The support conditions of the temporary enclosure panel can be optimized or optimized to accommodate the overall height of the enclosure. Further, according to the temporary enclosure structure using the spacer, since the axis of the horizontal member is arranged in the surface of the structure including the central axis of the adjacent column, the generation of stress due to the eccentric load is prevented. However, this makes it possible to stabilize the support and restraint of the temporary enclosure panel. On the other hand, according to the temporary enclosure structure using the eccentric attachment, when a wedge-coupled scaffold or the like is used as the base frame for the temporary enclosure, the components (horizontal member, handrail member, brace, etc.) of the wedge-coupled scaffold or the like are used. ) And the temporary enclosure panel can be prevented from interfering with each other, and a work space for wedge-connecting these scaffolding components to the vertical columns can be secured around the columns.
