Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a pillar that supports a sound insulation wall such as a highway, and more particularly to a Y-shaped pillar that is provided in a median strip of a road to individually insulate an oncoming lane.

[0002]

[Prior art]

 As shown in FIG. 3, sound insulation walls 20 are provided on both sides of the highway HW in order to block noise from the vehicle. Recently, the sound insulation wall 20 is provided not only on both sides of the road but also on the median strip CZ in order to enhance the sound insulation effect. The sound insulation wall on the side of the central separation band is provided with and supported by a Y-shaped support 1.

As shown in FIG. 4, the Y-shaped strut 1 is a branch strut formed by bending the H-shaped steel having a width about half that of the lower strut 2 in the width direction at the upper end of a straight lower strut 2. 3 and 4 are back-to-back and welded to each other, and a base plate 5 is welded to the lower end of the lower column 2.

[0004]

[Problems to be solved by the device]

 The above Y-shaped support 1 is a finished product at the factory and is delivered to the installation site because the branching supports 3 and 4 cannot be bent and the base plate 5 cannot be joined with high precision at the site.

However, the Y-shaped column has a problem that the height H is very large, about 7 to 8 m, and the width W is about 5 m, which makes it difficult to carry it by truck.

The present invention aims to eliminate such a problem.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, in a Y-shaped strut having a structure as shown in FIG. 4, one of the branch strut is divided at a position where a part of the lower strut is included, and this dividing strut is used as a fastening means. It was designed to be detachably attached to the lower column using.

[0008] The split struts may be fastened by providing a bolt joint at the mating portion with the lower strut and connecting them with each other, but the joint may be unstable only with this, so between the two branch struts. It is desirable to provide a joint for fastening with bolts and nuts, and also to connect the branch columns with this joint.

[0009]

[Action]

 When the detachable branch stanchion is removed, the width of the Y-shaped stanchion becomes about 1/2 (2.5 m) of the finished product, and there is no size restriction on transportation. Also, since the removed branch support can be loaded into the vehicle with the curving direction being the same as the curving direction of the other branch support, the loading efficiency is improved and the number of Y-shaped support per transfer can be increased. it can.

[0010]

[Embodiment of device]

 1 and 2 show an embodiment of a Y-shaped strut of the present invention. The Y-shaped column 1 is composed of a lower column 2, two branch columns 3, 4, a base plate 5 joined to the lower end of the lower column 2, and three connecting portions 6, 7, 8. .

The lower strut 2 is a straight strut made of H-shaped steel, and is made by attaching a reinforcing plate 9 to the middle portion of the web and further cutting out about 1/4 in the upper right in FIG.

The branch column 3 is made by bending an H-shaped steel having a width of about 1/2 of that of the lower column 2 in the width direction at a constant bending rate, and the lower end thereof is joined to the upper end of the lower column 2. It is integrated with the lower stanchion 2.

The other branch strut 4 has a curved portion 4a having the same structure as the branch strut 3, and a straight portion 4b which fits into the cutout portion of the lower strut 2 and is fitted to the lower end of the curved portion 4a. The structure is added. The straight portion 4b is made of H-shaped steel having the same size as the curved portion 4a.

The connecting portions 6 and 7 are connecting portions of a bolt joint provided at a joint portion between the lower support column 2 and the branch support column 4. The connecting portion 7 connects the straight portion 4b of the branch strut 4 directly to the reinforcing plate 9 with a bolt and a nut 10 (see FIG. 1 (c)), but the connecting portion 6 is an end portion of H-shaped steel. Since there is no part that can be bolted to, the L-shaped steel 6a is separately attached to the horizontal mating part so as to face it, and it is connected by bolts and nuts 10 (see FIG. 1 (b)).

The joint portion 8 is formed by welding joint plates 8a and 8b to the back-to-back surfaces of the branch struts 3 and 4, and stacking these plates to connect them with bolts and nuts 10. (See FIG. 1 (d)).

The Y-shaped support column 1 configured as described above is carried into the installation site with the branch support column 4 removed. Then, the branch support 4 is attached on site, then the Y-support is set up, and the base plate 5 is fixed on the seat surface with the studs to complete the installation.

Reference numeral 20 in FIG. 1 is a sound insulation wall. The sound insulation wall 20 is supported by the Y-shaped support columns 1 by fitting both ends of the sound insulation wall into the grooves of the Y-shaped support columns arranged at regular intervals, and supporting the upper and lower portions of the wall between the support columns with the furrow extending between the Y-shaped support columns. Done in.

[0018]

[Effect of device]

 As described above, in the Y-shaped support of the present invention, since the branch support on one side is detachable, it does not become bulky, and it is possible to carry out normal truck transportation without restrictions on transportation in terms of size.

Further, since it is possible to carry out the loading in which the direction of the removed branch column and the other branch column are aligned, the loading efficiency is improved and the transport cost per column is reduced.
