Abstract

(57) [Summary] [Problem] To support the construction fence so that it does not fall down even when the wind is strong. SOLUTION: The channel steel beam 11 has a length approximately twice as large as the width of the fence so that two construction fences 3 can be mounted thereon. A pair of legs 12 are provided near the ends of the beam 11 so as to protrude left and right, respectively. The leg 12 is provided with several holes 13 for passing an anchor. On the upper surface of the beam 11, sockets for receiving the columns 4 of the fence 3 are provided at the center and both ends of the beam, respectively. Center socket 15
Is formed in a box shape having a size such that two pillars 4 can be arranged in the axial direction of the beam. The end socket 16 comprises two plates 1
7 are welded on the beam 11 at intervals so that the fence posts can enter. These plates are actually made of angles, the other flange 18 of which forms a connecting plate for connecting the beams. The connecting plate 18 stands on the edge of the beam and has a bolt hole 19 in the center.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a support for erecting a construction fence on the ground or a road surface.

[0002]

[Prior art]

 In construction works and road works, the construction site will be surrounded by construction fences to ensure safety. Conventionally, stone stands were used to set up construction fences. As shown in Fig. 1, the stone bed 1 has a hole 2 in the upper surface of a disk-shaped concrete block, into which the support 4 of the construction fence 3 is inserted to support the fence. . There are two holes 2 in which the columns of the adjacent fence are inserted to connect the fences.

[0003] The stone bed usually weighs about 15 kg, but still, when the wind is strong, the fences may fall down, and it is very dangerous.

[0004]

[Problems to be solved by the invention]

 The purpose of this invention is to provide a support that can support the construction fence so that it does not fall even when the wind is strong.

[0005]

[Means for Solving the Problems]

 The reason that conventional stone stands cannot support the fence in strong winds is largely due to the fact that each stone stand is independent and does not cooperate with each other. Therefore, in the present invention, the support base is formed of an iron (for example, channel steel) beam having a length almost an integral multiple of the width of the construction fence. The legs are attached to the beams so that they protrude left and right. At both ends of the beam, connecting means for connecting to the adjacent beam will be provided. On this beam, a socket will be provided to receive the lower end of the column of the construction fence.

In order to erect a fence, the beams are placed on the ground, and the beams are connected to each other using connecting means, for example, bolts. Thus, the fence is erected by inserting columns into the socket above each beam.

[0007] Since the support base of the present invention is made of iron beams, it is heavy and does not fall down by a slight wind. In addition, unlike a conventional stone bed, the weight is not dispersed, and the entire beam acts as one weight. In this sense, it is difficult to fall down. Furthermore, since the legs are provided so that they protrude from side to side, there is little risk of falling down and safety is high.

If a hole is made in the leg and an anchor (a nail) is driven into the ground through the hole, the fence will not fall even with a stronger wind.

[0009]

[Embodiment of the invention]

 As shown in FIG. 2, the main part of the support base 10 is composed of channel steel beams 11. The beam 11 is about twice as long as the width (1.8 m) of the fence so that two construction fences 3 can be mounted. A pair of legs 12 are provided near the ends of the beams 11 so as to protrude left and right, respectively. As shown in FIG. 3, the ground surface of the leg 12 is provided at a position slightly lower than the beam 11. The leg 12 is provided with several holes 13 for passing an anchor.

[0010] On the upper surface of the beam 11, sockets for receiving the columns 4 of the fence 3 are provided at the center and both ends of the beam, respectively. The central socket 15 is formed by welding plates 15a and 15b to form a box having a size such that two columns (32 mm in diameter) 4 are arranged in the axial direction of the beam and fit exactly.

The end socket 16 welds the two plates 17 onto the beam 11 at an interval to accommodate the column 4. These plates are actually made of an angle material, and the other plate (flange) of the angle material constitutes a connection plate 18 for connecting the beams. The connection plate 18 stands on the edge of the beam and has a bolt hole 19 in the center.

When erecting a fence, the beam is carried to the installation location, and an anchor 20 (thick nail) is driven into the ground through a hole 13 formed in the leg 12 to fix the beam 11. Since the leg 12 is located lower than the beam, the leg 12 does not float off the ground even if the ground has some irregularities.

The beam and the beam are passed through a hole 21 of the connection plate 18 with a bolt 21 and fastened with a nut 22. After the beams 11 are installed, the fence posts 4 are inserted into the sockets 15 and 16 of the beams, respectively, and the fences are erected. Since the center socket 15 is large enough to fit two posts, the fence 3 does not move left and right. In addition, since the end socket 16 is loose in the longitudinal direction of the beam, it can be inserted even if the interval between the columns is slightly larger or smaller than a specified dimension.

[0014] There are cases where it is desired to allow a part of the fence to be moved for a work vehicle or the like to enter or exit. In such a case, as shown by a chain line in FIG. 3, a caster (an annulus) 23 can be attached below the leg 12 using the hole 13. That way, you can easily move with just a push.

[0015] The above-mentioned beam has a length that allows two fences to be erected. However, if one beam is required, a beam having a length half that of the above-mentioned beam may be used. In this case, sockets are not required at the center, but only at both ends. Then, a stopper 24 is provided on the end socket 16 as shown by a chain line in FIG. 2 so that the fence 3 does not shift in the axial direction of the beam.
