That is, in the assembled fence according to the present invention, a first tubular member 1 having a predetermined length provided with an upper connecting portion 2 and a lower connecting portion 3 which can be detachably connected to each other, and a lower connecting portion of the tubular member 1. A second tubular member 4 detachably connected to the portion 3 to form a substantially leg tube;
And a pair of receiving members 5a and 5b detachably attached to the first cylindrical member 1 to form a pole A. The receiving fittings 5a and 5b include a ring portion 6 rotatably inserted into a predetermined position on the outer periphery of the first cylindrical member 1, an engaging portion 8 formed on the ring portion 6 to receive the hook 7 of the pipe B. And a structure composed of

The upper and lower connecting portions 2 and 3 of the first cylindrical member 1 and the connecting means between the first cylindrical member 1 and the second cylindrical member 4 are preferably formed by screwing. May be performed by the means described above.

Further, large-diameter flanges 9 and 10 are formed on the outer periphery of the upper end portion and the intermediate portion of the first cylindrical member 1 so that when the plurality of first cylindrical members 1 are connected linearly, Flanges 9,10
If the receiving fittings 5a and 5b are sandwiched and held between them, the receiving fittings 5a and 5b can be easily attached to a predetermined position while connecting the first cylindrical members.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in the drawings, the assembled fence according to the present invention includes a pole A and a pipe B detachably connected to the pole A and serving as a substantial cross rail.

The pole A has a first cylindrical member 1 having a predetermined length provided with an upper connecting portion 2 and a lower connecting portion 3 which can be detachably screwed to each other, and a lower connecting portion 3 of the cylindrical member 1. It is formed by a second tubular member 4 which is detachably screwed and connected to form a substantially leg tube, and a pair of receiving members 5a and 5b which are detachably attached to the first tubular member 1. The receiving fittings 5a and 5b include a ring portion 6 rotatably inserted at a predetermined position on the outer periphery of the first cylindrical member 1, and an engaging portion 8 formed on an outer surface of the ring portion 6 to receive the hook 7 of the pipe B.
And is constituted by.

[0010] Large-diameter flanges 9, 10 are formed on the outer periphery of the upper end portion and the intermediate portion of the first cylindrical member 1, and a plurality of first cylindrical members 1 are linearly arranged as shown in FIG. When connected, the flange 10 of the upper first cylindrical member and the flange 9 of the lower first cylindrical member
It is configured to hold the receiving fittings 5a, 5b between them. Thus, the first metal members can be connected to each other, and at the same time, the receiving members 5a and 5b can be easily attached to the predetermined positions.

Further, a large-diameter flange 4b is formed on the outer periphery of the upper end of the second cylindrical member 4, and when the first cylindrical member is linearly connected to the upper end of the second cylindrical member 4, the second cylindrical member 4 is formed. Collar part 4b
And the flange 5 of the first tubular member 1
a and 5b can be fixedly held.

The receiving members 5a and 5b have their engaging portions 8, 8 extending in opposite directions, respectively. As shown in FIG.
a, 5b are attached to the first tubular member 1 when the engaging portions 8,
8 are designed to be at the same horizontal level.

The above-mentioned assembled fence is constructed by inserting the base of the second tubular member 4 into a hole formed in a concrete base block 11 and standing upright at predetermined intervals, and
The lower connecting portion 3 of the first cylindrical member is screwed and connected to the upper connecting portion 4a of the second cylindrical member 4, and the receiving fittings 5a, 5b are provided between the flange 4b and the flange 10 of the first cylindrical member 1. Hold.
Further, another first cylindrical member 1 is screwed and connected to the upper end of the first cylindrical member 1 connected to the second cylindrical member 4 as shown in FIG. Part 10 and the lower first
The receiving fittings 5a and 5b are sandwiched and held between the flanges 9 of the tubular member.

The metal fittings 5a held in this manner,
The fence is assembled by inserting the hook 7 of the pipe B, which is a substantial horizontal rail, into the engaging portions 8, 8 of 5b from above as shown in FIGS. In this case, the height of the fence can be freely changed by increasing or decreasing the number of attachments of the first tubular member 1.

At the time of this assembling, the receiving fittings 5a,
5b is rotatable around the first tubular member 1, so that the relative positions of the engaging portions 8, 8 of the two receiving members 5a, 5b can be arbitrarily expanded, for example, by 180 degrees as shown in FIG. Position,
Alternatively, a 90-degree position as shown in FIG.
It can be attached at a position of 0 degrees or any other angle, so that the attachment direction of the horizontal rail to the pole can be set arbitrarily in the radial direction.

In the present invention, as shown in FIG. 9, if a third cylindrical member 12 cut from the upper end of the intermediate flange portion 10 of the first cylindrical member 1 is prepared separately, the pole assembly can be minimized. By attaching the third tubular member 12 to the upper stage, an extra protruding portion can be eliminated and the appearance as a fence can be adjusted.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited only to the structures of the embodiments, but has the structural requirements and achieves the above object. However, as long as it has the following effects, it can be appropriately modified and implemented.

[0018]

Since the assembled fence of the present invention is constructed as described above, the height of the fence can be adjusted according to the needs of the construction site by increasing or decreasing the number of the first cylindrical members and setting the total length of the pole. Can be changed arbitrarily.
By rotating a pair of receiving fittings attached to the cylindrical member, the relative positions of these engaging portions can be arbitrarily changed, whereby the mounting direction of the horizontal rail to the pole can be arbitrarily changed in the radial direction. Can be set. In addition, it can be assembled very simply and securely without using any fittings such as connecting fittings and mounting screws, and can be easily disassembled, thus speeding up work on site. There is a remarkable effect that it can be achieved.
