Hereinafter, embodiments of this invention will be described based on the drawings. 1 to 3 show an embodiment of this invention. A road sign temporary fixing device 30 of this embodiment temporarily fixes a road sign 1 to a guardrail 2. It consists of a bracket metal fitting 10 for holding the bracket and a fitting 32 for attaching the bracket metal fitting 10 to the guardrail 2. The bracket 10 is as described in the prior art section above.

Next, the fixture 32 will be explained based on FIG. 2. The fixture 32 includes an abutment plate 34 that abuts against the roadway side surface 2c of the guardrail 2 located on the roadway side. The abutment plate 34 is a plate body long in one direction, and one end in the longitudinal direction is an upper end 34a located at the upper end 2a of the guardrail 2, and the other end is a lower end located at the lower end 2b of the guardrail 2. This is the section 34b. A plurality of fold lines 36 intersecting in the longitudinal direction are provided between the upper end part 34a and the lower end part 34b, and the guardrail 2 is bent along the fold lines 36 to form a shape that follows the unevenness of the roadway side surface 2c. Six fold lines 36 are provided here, two near the upper end 34a and two near the lower end 34b are normally folded so as to convex toward the roadway at an obtuse angle, and the two in the center are folded at an obtuse angle toward the roadway. It is reversely folded so that it is concave. As a result, portions close to the upper end 34a and the lower end 34b are bent from the center portion 34c, which is a rectangular plane located at the center, into an M shape that projects toward one outer side surface 34d of the plate surface. The number and folding angle of the folding lines 36 are changed as appropriate depending on the guardrail 2 to be attached.

At the upper end 34a and the lower end 34b, retaining plates 38, which abut and hold the pole 1a of the road sign 1, are continuously provided. Among the pair of retaining plates 38, the upper retaining plate 38a provided at the upper end 34a is a rectangular plane that is folded back from the upper end 34a to approach the center portion 34c, and is approximately the same as the center portion 34c. are located on the same plane. A pair of positioning portions 40 are provided on the surface of the upper holding plate 38a opposite to the contact plate 34, which contact both sides of the pole 1a in the longitudinal direction.

The positioning parts 40 are formed by attaching a pair of metal round bars cut to a predetermined length along the longitudinal direction of the contact plate 34, and the distance between the pair of positioning parts 40 is such that the pole 1a is on top. This is the length that touches both sides of the pole 1a in the longitudinal direction when it comes into contact with the holding plate 38a. On the inside of the corner where the upper end 34a of the abutting plate 34 intersects with the upper holding plate 38a, there is provided a displacement prevention part 42 that prevents a gap (displacement) that occurs when the guardrail 2 is attached to the upper end 2a of the guardrail 2. . The slippage prevention part 42 is formed by cutting a metal round bar into a predetermined length and attaching it so as to intersect with the longitudinal direction of the upper holding plate 38a, so as to share the same material as the positioning part 40.

The lower holding plate 38b provided at the lower end portion 34b is a rectangular plane extending to the side opposite to the center portion 34c, and is located on substantially the same plane as the center portion 34c. A pair of positioning portions 40 are provided on a surface of the lower holding plate 38b that is continuous with the surface opposite to the outer surface 34d of the abutment plate 34, and are in contact with both sides of the pole 1a in the longitudinal direction. The positioning parts 40 are formed by attaching a pair of metal round bars cut to a predetermined length along the longitudinal direction of the contact plate 34, and the distance between the pair of positioning parts 40 is such that the pole 1a is below the This is the length that touches both sides of the pole 1a in the longitudinal direction when it comes into contact with the holding plate 38b.

A portion of the abutment plate 34 adjacent to the upper end portion 34a is an upper surface portion 34e located approximately at right angles to the center portion 34c. A locking protrusion 44 with which the guardrail claw portion 22 of the bracket fitting 10 locks is provided on the outer surface 34d of the abutment plate 34 at a position near the upper end portion 34a and a little away from the upper surface portion 34e. . The locking protrusion 44 has a support portion 46 which is a plate body rising outward from the outer surface 34d of the contact plate 34, and the support portion 46 has the same width as the width direction perpendicular to the longitudinal direction of the contact plate 34. It is. A locking rod portion 48 is integrally provided at the tip of the support portion 46 . The locking rod portion 48 is formed by attaching a metal round rod cut to a predetermined length, and the longitudinal direction of the locking rod portion 48 is approximately perpendicular to the longitudinal direction of the contact plate 34. It is approximately parallel to the outer surface 34d and has a length that projects from both sides of the support portion 46. The length is, for example, approximately twice the width of the support portion 46. The locking protrusion 44 is provided on the outer surface 34d located diagonally with respect to the central surface 34c, and protrudes laterally at an obtuse angle with respect to the central portion 34c.

A locking protrusion 44 is also provided on the outer surface of the lower holding plate 38b near the lower end portion 34b, which is continuous with the outer surface 34d of the abutment plate 34. Since the lower holding plate 38b is located on substantially the same plane as the central portion 34c, the locking protrusion 44 protrudes laterally at approximately right angles to the central surface 34c.

Next, a method of using the road sign temporary fixing device 30 will be explained. First, the fixture 32 is set on the roadway side of the guardrail 2. At this time, the longitudinal direction of the abutting plate 34 of the fixture 32 is attached to the guardrail 2 substantially perpendicularly, and the upper end 34a, which is one end in the longitudinal direction, is located at the upper end 2a of the guardrail 2, and the other lower end 34b is located at the lower end 2b of the guardrail 2. A plurality of fold lines 36 intersecting in the longitudinal direction of the abutting plate 34 match the fold lines along the longitudinal direction of the guardrail 2, and follow the uneven shape of the roadway side surface 2c of the guardrail 2. The upper holding plate 38a and the lower holding plate 38b of the holding plate 38 provided at the upper end 34a and lower end 34b of the contact plate 34 are located on the opposite side of the guardrail 2 from the roadway, and A positioning section 40 is located on the surface. The upper end 2a of the guardrail 2 is located inside the corner where the upper end 34a of the contact plate 34 intersects with the upper holding plate 38a, and the upper end 2a of the guardrail 2 is installed, and the slip prevention part 42 prevents the gap (shift) that occurs when it is installed. do.

Then, the road sign 1 is placed in contact with the guardrail 2 on the opposite side of the roadway, and the pole 1a is brought into contact with the upper holding plate 38a and the lower holding plate 38b. In this state, the pole 1a is positioned between the pair of positioning parts 40.

Next, one bracket metal fitting 10 is set on the upper end 2a of the guardrail 2. At this time, the holding plate 12, bolt 16, moving plate 18, and handle 26 are located on the opposite side of the guardrail 2 from the roadway. Then, the holding plate 12 is brought into contact with the pole 1a on the opposite side of the guardrail 2 from the roadway. At this time, the guardrail claw part 22 is set so as to protrude downward, and the locking part 20 passes through the side of the pole 1a, further passes through the upper end 2a of the guardrail 2, and projects toward the roadway side of the guardrail 2. . Then, with the pole 1a and the guardrail 2 in between, it is hooked onto the locking rod portion 48 of the locking protrusion 44 provided near the upper end 34a of the fixture 32 from above on the roadway side. Then, the handle 26 is rotated, the bolt 16 is rotated around the axis, the holding plate 12 is pushed with the nut 15 and moved away from the moving plate 18, and the pole 1a and the guardrail 2 are tightened together, and the pole 1a is held at the top. It is pressed against the plate 38a and the positioning part 40 and held in the vertical direction.

Next, another bracket metal fitting 10 is set on the lower end 2b of the guardrail 2. As in the case of setting on the upper end 2a, the holding plate 12, bolt 16, moving plate 18, and handle 26 are located on the opposite side of the guardrail 2 from the roadway, and the holding plate 12 is placed on the roadway of the guardrail 2 of the pole 1a. Place it in contact with the opposite side. At this time, the lower end 2b is set in such a direction that the guardrail claw portion 22 protrudes upward. The locking portion 20 then passes through the side of the pole 1a, further passes through the lower end 2b of the guardrail 2, and projects toward the roadway side of the guardrail 2. Then, with the pole 1a and the guardrail 2 in between, it is hooked onto the locking rod part 48 of the locking protrusion 44 provided on the lower holding plate 38b of the fixture 32 from below on the roadway side. Then, the handle 26 is rotated, the bolt 16 is rotated around the axis, the holding plate 12 is pushed with the nut 15 and moved away from the moving plate 18, and the pole 1a and the guardrail 2 are tightened together, and the pole 1a is held downward. It is pressed against the plate 38b and the positioning part 40 and held in the vertical direction.

As a result, the pole 1a is attached to the guardrail 2 at two locations in the longitudinal direction, held in the vertical direction, and securely temporarily fixed. Since the center surface 34c of the contact plate 34 is located on almost the same plane as the upper holding plate 38a and the lower holding plate 38b, the pole 1a interferes with the guardrail 2 as shown in FIG. The plate 34 is elastically deformed so as to bulge out toward the roadway side to an appropriate extent and comes into close contact with the guardrail 2, so that the pole 1a does not interfere with the guardrail 2.

When the road sign 1 is no longer needed, operate the handle 26 of the bracket 10 to rotate the bolt 16 around the axis in the opposite direction to the temporary fixing, move the holding plate 12 close to the movable plate 18, and remove the pole 1a. and release the fastening of the guardrail 2, and remove the road sign 1 from the guardrail 2. The removal work is also performed on the opposite side of the guardrail 2 from the roadway.

According to the road sign temporary fixing device 30 of this embodiment, the structure is simple and the cost is low, and a worker can safely attach the road sign 1 to the guardrail 2 on the opposite side of the guardrail 2 from the roadway. be able to. A conventionally used bracket metal fitting 10 can be used and is easily available. The pole 1a of the road sign 1 is attached to the guardrail 2 at two locations in the longitudinal direction, and is held in the vertical direction by the positioning part 40, so that it is securely temporarily fixed without falling down. The abutment plate 34 of the fixture 32 has a shape that follows the roadway side surface 2c of the guardrail 2, and further elastically deforms so as to bulge out toward the roadway side to an appropriate extent, so as to tightly adhere to the roadway side surface 2c of the guardrail 2 to prevent rattling. . Since the upper end 34a of the abutment plate 34 is provided with a displacement prevention portion 42, the upper end 2a of the guardrail 2 does not shift and can be reliably attached. In addition, since the pole 1a of the road sign 1 can be temporarily installed on the opposite side of the guardrail 2 from the roadway, when an accident vehicle or the like contacts the guardrail 2, the pole 1a and the bracket 10 do not become protrusions and can be used as secondary It is expected that the damage will be reduced. Furthermore, if the temporarily installed pole 1a separates from the guardrail 2 due to loosening of the bracket fittings 10 due to human error or the like, the probability is that it will be less likely to fall toward the roadway, making it less likely that secondary damage will occur.

Note that the temporary road sign fixing device of this invention is not limited to the above embodiment, and can be modified as appropriate. The size and shape of the fixture can be changed to match the guardrail to which it is attached. The shape and position of the locking protrusion of the fixture can be changed as long as it can be securely locked to the guardrail claw of the bracket. The positioning part and the displacement prevention part may be provided using other than round rods.
