Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a structure of a connecting portion of a barrier wall such as a soundproof wall or a protective wall, which is particularly constructed on a highway, an elevated road, a railroad track, or the like. .

<Prior art> On a highway, etc., a barrier wall is constructed between the route and the surroundings in order to prevent noise in the area surrounding the route or prevent people from entering the route from the surroundings. Is being done.

The barrier wall is generally a continuous wall formed by inserting a wall panel such as a precast concrete plate, an extruded cement plate or an asbestos cement plate between the grooves formed by the flanges of H-shaped steel material that are erected at appropriate intervals. I am configuring.

The structure of the connecting portion of the H-shaped steel material important for construction of the barrier wall is disclosed in, for example, Japanese Utility Model Laid-Open No. 61-188612.

That is, in order to prevent damage to the support portion of the wall panel supported by the H-shaped steel material due to vibrations caused by various noises and to prevent the vibrations from being transmitted to other wall panels, which is particularly effective for soundproof walls. A cushioning material such as a rubber sheet is interposed between the inner surface of the flange of the H-shaped steel material and the surface of the wall panel. In order to fix the wall panel fixedly in the groove of the H-shaped steel material, a tapered surface is formed on the inner surface of the flange on one side of the H-shaped steel material, and a wedge member made of hard rubber or the like is used for the tapered surface. There is used a means for interposing and fixing by tightening with through bolts.

<Problems to be Solved by the Invention> However, the structure of the connecting portion as described above is complicated from the viewpoint of construction or member structure, and also has a substantial problem from the viewpoint of fixing the wall panel.

That is, in order to position the wall panel fixedly, it is necessary to previously form a tapered surface on the inner surface of the flange of the H-shaped steel material. H
As the structural steel material, a structural steel material having a standard shape is generally provided. When this is used, the above-mentioned tapered surface means that a separate taper forming member is positioned and arranged on the inner surface of the franchise, or an H-shaped steel material. When it is formed integrally with the, a special forming process for that is required. Also, since the wall panel is only located between the flange surfaces of the H-shaped steel material by being sandwiched by the cushioning material and the wedge member, especially when a relatively large vibration is repeatedly received, such as a blocking wall of a railroad track, There is a risk that the wall panel may slip in the surface direction and may collide with the H-shaped steel web to damage the end portion of the wall panel. All of these are problems that structurally, economically, and functionally require a solution.

In view of the above conventional problems, it is the present invention to provide them in order to solve them.

It is an object of the present invention to provide a structure of a connecting portion of a blocking wall that is easy to construct and has a durable and reliable support for fixing a wall panel.

<Means for Solving the Problems> In order to achieve the above object, the connection portion of the barrier wall according to the present invention has an elastic sheet interposed between the inner surface of one flange of the H-shaped steel material and the opposing wall panel surface. The H-shaped steel material has a structure in which a fixing member is interposed between the inner surface of the other flange of the H-shaped steel material and the facing wall panel surface, and is fastened to the H-shaped steel material by a bolt to press and fix the wall panel. A wedge member that is bolted to the web of the H-shaped steel material with the panel facing surface side as the taper surface, and a surface that faces the wedge member is a taper surface, and a contact surface of the H-shaped steel material with the web and a wall panel. And an elastic pressing member forming a contact surface and a stopper surface located between the web and the end surface of the wall panel.

<Operation> The holding member for pressing the wall panel supports and fixes the wall panel to the H-shaped steel material by bolting the wedge member.

In this case, since one surface of the wall panel is supported by the elastic sheet and the other surface is supported by the elastic pressing member, the vibration and the like are absorbed by the both. When the vibration is larger than the absorption vibration, the wall panel slips in its surface direction, but the stopper surface of the pressing member is located between the H-shaped steel web and the end surface of the wall panel. The buffer function of the stopper surface allows it to be received without damaging the wall panel.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan sectional view showing a structure of a connecting portion of a barrier wall according to the present invention.

In the figure, 1 is an H-shaped steel material, and 2 is a wall panel, which is formed of a concrete wall member such as a precast concrete slab or an extrusion-molded cement slab (the figure shows a hollow panel having a large number of elongated hollows). ). 3 is an elastic sheet made of a rubber material or the like, which is interposed between the inner surface of one flange 1a of the H-shaped steel material 1 and the facing surface of the wall panel 2,
The vibration of one side is not transmitted to the other side.

Reference numeral 10 denotes a fixing member for the wall panel 2, which is composed of two members interposed between the wall panel 2 and the inner surface of the other flange 1b, and one member is fastened to the web 1c of the H-shaped steel material 1 with a bolt B. I have to.

In the illustrated example, the wall panels 2, 2 are provided on both sides of the H-shaped steel material 1.
And the fixing members 10 and 10 are used to fix the respective wall panels 2 and 2, respectively, so that the bolt B is used for the web 1c of the H-shaped steel material 1 and both fixing members 10 and 10. The length is such that it can be penetrated and fastened together. Therefore, when the wall panel 2 is only one such as the end of the blocking wall, the bolt B has a length for fastening the fixing member 10 on one side and the web 1c.

The fixing member 10 is composed of a wedge member 11 and a pressing member 12.

The wedge member 11 is made of a metal or a hard rubber material, and the bolt B
With this, the H-shaped steel material 1 is fastened to the web 1c, and a taper surface 11a is formed on the surface side facing the wall panel 2 at the time of fastening.

Further, the pressing member 12 is made of an elastic material such as a hard rubber material, the surface facing the wedge member 11 is a tapered surface 12a, and the contact surface 12b contacting the web 1c and the surface of the wall panel 2 are provided. To form a wall panel contact surface 12c that abuts against, and a stopper surface 12d located between the web 1c and the end surface of the wall panel 2.

The length of the fixing member 10 composed of both members 11 and 12 (the direction orthogonal to the paper surface in the drawing) is set in accordance with the design specifications determined for fixing the wall panel 2. In the case of this type, the panel 2 is generally short because it is partially attached in the vertical direction.

When the wall panel 2 is positionally fixed to the H-shaped steel material 1 in the above configuration, as described above, first, the elastic sheet is provided between the inner surface of the flange 1a of the H-shaped steel material 1 and the wall panels 2, 2.
Interpose 3,3. Then, the pressing members 12, 12 are respectively inserted and interposed between the inner surface of the other flange 1b and the wall panels 2, 2. At the time of this insertion, for example, an adhesive is applied to the contact surfaces 12b, 12b of the pressing members 12, 12 with the web 1c of the H-shaped steel material 1 and / or the contact surfaces 12c, 12c with the wall panels 2, 2. To insert. Next, the wedge members 11, 11 are inserted between the flange 1b of the H-shaped steel material 1 and the pressing member 12 with the tapered surfaces 11a, 11a thereof facing the pressing member 12 side. Then, the bolt B is inserted from one side (the left side in the figure) of the wedge member 11 to the other side through the bolt insertion hole 1b of the H-shaped steel material 1, and the wedge members 11 and 11 are pressed together with the nut N. .

By the above clamping, the wedge member 11 presses the pressing members 12, 12 by the wedge action of the tapered surface 11a, and the pressing members 12, 12 press the wall panels 2, 2 toward the flange 1a side of the H-shaped steel material 1. Fix it.

In the above fixing, the wall panels 2, 2 are fixed firmly and evenly and evenly in close contact with the pressing members 12, 12 and the elastic sheets 3, 3 due to the elasticity thereof. Then, when a deviation occurs in the surface direction of the wall panels 2, 2 due to vibration or the like, the end surfaces of the wall panels 2, 2 are buffered and received by the stopper surfaces 12d, 12d of the pressing members 12, 12, that is, the wall. Prevents damage to panels 2 and 2.

<Effect of the Invention> As described in detail above, according to the present invention, the wall panel can be reliably fixed to the H-shaped steel material by using the fixing member having a simple structure. In this case, since the sliding action in the surface direction of the wall panel is buffered and received by the stopper surface of the pressing member, the buffering of the wall panel to the H-shaped steel material is prevented and the wall panel is prevented from being damaged. It can be effectively prevented.
