Description

  The present invention relates to a structure for attaching an exterior plate to a road side surface of a rigid protective fence erected at an end portion in the transverse direction of an elevated road or a road bridge. Here, the rigid guard fence is a guard fence that allows only deformation within elastic deformation of a main member constituting the guard fence.

  Japan's road infrastructure has been rapidly improved since the period of high growth, and at present, how to extend its service life has emerged as an important issue. On the other hand, a huge amount of concrete structures are used for road infrastructure. For this reason, how to extend the life of concrete structures in road infrastructure has become an urgent issue.

  One concrete structure in road infrastructure is a rigid guard fence made of concrete. Unlike floor slabs and girders, rigid guard fences usually do not receive external force, so they are considered to be less noticeable than floor slabs and girders. It is a structure that protects the life of the plant, and measures for extending the service life are also important in the rigid protective fence.

  On the other hand, the road side surface of the rigid protective fence is a structure that enters the field of view of a vehicle occupant such as a driver, and is preferably aesthetically pleasing.

  Here, looking at the technologies currently proposed as a technology for repairing the rigid protective fence, Patent Documents 1 and 2 propose a technique for reinforcing the rigid protective fence.

  However, in the techniques described in Patent Documents 1 and 2, a large number of anchor bolts penetrating the rigid protective fence are provided, and reinforcing plates are installed on both side surfaces of the rigid protective fence. Providing anchor bolts that penetrate the rigid protective fence means that a through hole is provided in the rigid protective fence, which is not preferable from the viewpoint of extending the service life.

  Hereinafter, with reference to the drawings, a structure for attaching an exterior plate to a road side surface of a rigid protective fence according to an embodiment of the present invention will be described in detail.

(First embodiment)
FIG. 1 is a cross-sectional view (a cross-sectional view cut along a plane orthogonal to the direction in which a road extends) showing a structure for attaching an exterior plate to a road side surface of a rigid protective fence according to a first embodiment of the present invention.

  As shown in FIG. 1, the attachment structure 10 of the first embodiment is a structure in which an exterior plate 14 is attached to a side surface on the road side among the side surfaces of the rigid protective fence 90.

  A ground cover 92 is provided above the floor slab 94, and a rigid protective fence 90 is provided above the ground cover 92. The rigid protective fence 90 is provided above the ground cover on a road having a ground cover. It is a rigid protective fence.

  The mounting structure 10 of the present embodiment includes a top beam member 12 and an exterior plate 14.

  The top beam member 12 is a groove-shaped member and has two flange portions 12A and 12B (the flange portion 12A is on the road side and the flange portion 12B is on the opposite side of the road). The top beam member 12 has a web portion 12C covering the top portion 90A of the rigid protective fence 90, and the two flange portions 12A and 12B of the top beam member 12 are disposed on both sides of the top portion 90A of the rigid protective fence 90. It is arranged so as to be sandwiched. Since the two flange portions 12A and 12B of the top beam member 12 sandwich the both side surfaces of the top portion 90A of the rigid protective fence 90, they can be called sandwiched portions. Further, the web portion 12C of the top beam member 12 connects the two flange portions 12A and 12B of the top beam member 12 which is a sandwiching portion, and thus can be referred to as a connecting portion.

  The top beam member 12 is produced so that the distance between the two flange portions 12A and 12B (the width of the web portion 12C of the top beam member 12) matches the thickness of the top portion 90A of the rigid guard fence 90.

  When the top 90A of the rigid guard fence 90 is sandwiched between the two flanges 12A and 12B of the top beam member 12, the flanges 12A and 12B of the top beam member 12 and the top 90A of the rigid guard fence 90 are connected. For example, a sheet material having a shape following property may be interposed therebetween. By interposing a sheet material or the like having shape conformability, the top beam member 12 can be stably attached even if there is some unevenness on the side surface of the top portion 90A of the rigid protective fence 90.

  Further, when the top 90A of the rigid guard fence 90 is sandwiched between the two flange parts 12A, 12B of the top beam member 12, the flanges 12A, 12B of the top beam member 12 and the top 90A of the rigid guard fence 90 are An adhesive may be interposed between them.

Integration with the fence 90 becomes stronger.

  In addition, if the top portion 90A of the rigid guard fence 90 can be sandwiched between the two flange portions 12A and 12B of the top beam member 12 sufficiently firmly, the web portion 12C of the top beam member 12 is formed of the rigid guard fence 90. For example, a circular hole or the like may be formed in the web portion 12C of the top beam member 12 to reduce the weight.

  In addition, if the top portion 90A of the rigid guard fence 90 can be sandwiched between the two flange portions 12A and 12B of the top beam member 12 sufficiently firmly, the top beam member 12 is continuous along the rigid guard fence 90. For example, the length of about 20 to 30 cm may be arranged with a predetermined interval (for example, about 20 to 30 cm).

  Moreover, although the top beam member 12 can use a shape steel besides the member which built up the steel plate, the material is not necessarily limited to steel and the member which is not made of steel may be used. For example, a member formed of concrete, high-strength plastic, FRP, or the like may be used. Moreover, you may mix and use them.

  The upper end portion of the exterior plate 14 is attached to the web portion 12 </ b> C of the top beam member 12 by the stud 16, and the lower end portion of the exterior plate 14 is attached to the upper surface of the ground cover 92 by the anchor 18.

On the other hand, the anchor 18 to which the lower end portion of the exterior plate 14 is attached is embedded in the upper surface of the ground cover 92, but is not embedded in the rigid protective fence 90.

  Therefore, in the mounting structure 10 of the first embodiment, neither the stud 16 nor the anchor 18 is embedded in the rigid protective fence 90, and the rigid protective fence 90 is not damaged. There is no negative impact on the 90 lifetime.

  When the exterior plate 14 is attached to the rigid protective fence 90 via the stud 16 and the anchor 18, the hyperrod nut (registered) is used in that it can be surely prevented from loosening and falling off and the performance can be maintained even after repeated use. (Trademark) is preferably used.

  In the first embodiment, the stud 16 is attached to the web portion 12C of the top beam member 12. However, the stud 16 may be attached to the flange portion 12A that is the road-side flange portion of the top steel member 12. In this case, it is not necessary to extend the exterior plate 14 to the upper surface of the rigid protective fence 90.

  Next, the effect in the attachment structure 10 of this embodiment is demonstrated.

  Moreover, since the road side surface of the rigid protection fence 90 is covered with the exterior plate 14, it is possible to suppress deterioration of concrete due to exhaust gas, moisture, antifreezing agent, temperature change, and the like. This contributes to extending the life of the rigid protective fence 90.

  Further, the place where the anchor needs to be attached to the concrete is only the upper surface of the ground cover 92 to which the anchor 18 is attached, and the search for the position of the reinforcing bar inside the concrete may be performed only on the upper surface of the ground cover 92 to which the anchor 18 is attached. Further, the top beam member 12 only needs to be mounted on the top 90 </ b> A of the rigid protective fence 90. Therefore, construction can be performed easily and quickly.

  Further, the upper end portion of the exterior plate 14 is attached to the top beam member 12 by the stud 16, and the lower end portion of the exterior plate 14 is attached to the upper surface of the ground cover 92 by the anchor 18. Can be attached stably.

  Moreover, the material of the exterior board 14 is not specifically limited, For example, steel, a plastic, FRP etc. can be used. Moreover, you may mix and use them.

  Further, by using a laminated steel plate or a color steel plate having excellent weather resistance and aesthetics for the exterior plate 14, the aesthetics of the mounting structure 10 can be improved and the aesthetics can be maintained for a long time. In addition, by using a laminated steel plate with excellent weather resistance and aesthetic appearance, on-site painting is not required, and rapid construction is possible.
