3. Tighten the tightening nut through the washer on the end face of the connecting rod insertion hole of the column. By this operation, the crossbar between the columns is firmly fixed between the left and right columns (Fig. (C)).

4. A cross bar is externally fitted to the connecting rod from the right side, and the left end of the cross bar is fitted into the cross bar fitting cavity of the column. (Figure (D)).

The above operations 1 to 4 are repeated.

In addition, a short bolt with nut (6a) shown in Fig. 3 is used for the prop at the start end of the outer fence, and it is No. 4 for the end strut of the outer fence.
Using all screws shown in the figure or short bolts with both screws (6b), connect according to the above-mentioned connecting method, and insert a synthetic resin terminal cover (10) into the end fitting cavity to cover it. do it.

Next, the structure for preventing the rotation of the cross bar at the time of low temperature shrinkage will be described.

That is, the pseudo wooden outer fence is provided with a washer fitting portion (14) at one end of the column (1) having the crossbar fitting cavity (2) and the connecting rod insertion hole (3) and the inner cavity (5). A cross bar (4), a connecting rod (6) that inserts through the connecting rod insertion hole (3) of the column, and a horizontal washer fixing washer (11), and a tightening nut (8) at one end of the connecting rod. A threaded portion (7) screwed together is provided, and a connecting nut (9) screwed to the threaded portion is fixedly provided at the other end, and the cross bar fixed washer (11)
Comprises a cross-bar lumen fitting portion (12) and an insertion hole abutting portion (13).

The method of connecting the pillar and the crossbar is the same as the method described above,
A washer which is interposed between the tightening nut and the connecting rod insertion hole of the strut is provided with a crossbar rotation preventing function, and correspondingly, the crossbar inner cavity and the like are slightly modified.

The length of the connecting rod is preferably the space between the left and right columns.

The horizontal bar washer (11) is composed of a horizontal bar lumen fitting part (12) and an insertion hole abutting part (13). For example, as shown in FIG.
The vertical plate, which is a metal plate bent in a letter shape and has the insertion hole for the connecting rod in the center, is square and has an insertion hole abutment part (13) .The insertion hole abuts on the end surface of the insertion hole of the column. It is adapted to abut and fit into a rectangular recess formed corresponding to the portion (13),
The rectangular horizontal plate forms a crossbar lumen fitting portion (12), and is fitted to a washer fitting portion (14) at the end of the crossbar lumen.

After fitting the insertion hole abutting part of this crossbar fixed washer into the concave part of the insertion hole part of the column and tightening it with the tightening nut of the connecting rod, the washer fitting part at the end of the crosspiece is the inner space of the washer of the washer. The cross bar is fitted into the cross bar fitting cavity of the strut so as to fit into the fitting portion, and the above-described connecting operation of the strut and the cross bar is repeated. By this connection method, the insertion hole abutting portion of the horizontal bar fixed washer and the horizontal bar lumen fitting section are fitted to the column, the horizontal bar recess and the fitting section, respectively, and as a result, the horizontal bar and the column are inserted through the washer.
