2. Description of the Related Art Generally, a temporary fence installed over a length of several tens to several hundred meters per construction site has an existing building, a corner, a vehicle gate,
There are small gates for people to enter and exit, and areas that serve as boundaries such as height differences between lands, and if the surrounding boards that connect these areas in a straight line are placed in parallel with each other, the enclosure boards with a certain width are arranged in parallel. However, in many of those sides, a narrow space that is not enough for one shroud remains.

In the past, it has been customary to close the remaining narrow space with a steel closing plate manufactured according to the size of the space. FIG. 6 is a perspective view exemplifying this. Here, in order to enhance the appearance of the fence from the outside, the outer exposed surface of the enclosure plate is a flat surface. In the figure, 41 is an existing building, 42 is a corner wall, and 43 is a vehicle gate. Here, the corner shroud 42 is usually formed by interconnecting two plate-like members 42a having a width half the predetermined width of the shroud with hinges 42b or by pressing a shroud with a predetermined width. By
It is constructed by bending it to a required angle at its half width position, and such a corner enclosing plate 42 has a pipe frame 44 with hooks attached to its flange portion projecting to the rear side.
The corners of the temporary fence are defined by engaging with the horizontal pipe 44a.

Here, between the existing building 41 and the corner enclosure plate 42, and between the corner enclosure plate 42 and the vehicle gate 43.
In each of the space between and, the enclosure plates 45 are sequentially arranged in parallel from one side, and the respective enclosure plates 45 are
It is hooked to the pipe framework 44 almost in the same way as the corner enclosure plate 42, and the remaining spaces 46, 47 having a narrower width than the one enclosure plate 42 are generated in each side by this. The both ends of the closing steel plates 48, 49 cut into a width corresponding to the above are closed by screwing or adhering tape to the adjacent enclosure plate. In addition, in some cases, the space 46 generated in the vicinity of the corner portion is formed by the plate member 42a of the corner enclosing plate 42.
It was sometimes removed by adjusting the width of etc.
