DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for temporarily installing a support rail for a sign on a guard rail, a support for the guard rail, or a lid of a gutter in a case where there is no space for erecting a support pillar for a sign on a side of a road. The present invention relates to a sign support device for various guide signs used during road construction.

[0002]

2. Description of the Related Art Hitherto, there have been provided a large number of sign support devices for various guide signs used for road construction and the like, which can be temporarily installed on guardrails or columns of guardrails. For example, when the guide rail is mounted on the guard rail or on this pillar, various guide signs are fixed to the guard rail or on the mounting bracket for mounting on this pillar by screwing means using fastening bolts. It is fixed by stopping means. The screw means is securely mounted using a tool such as a spanner.

[0003]

In the above sign support devices for road works and the like, since fastening bolts are used in each case, a tightening tool such as a spanner is required. In addition to spending time, several people have to work. Since the number of the temporary guide signs to be attached is several tens or more at the site of road construction or the like, it is most desirable that they can be attached efficiently by one person.

Therefore, there has been proposed a sign support device in which a clamp mechanism is opened and closed by a lever operation so that a guide sign can be attached to and detached from a guard rail and this support by one-touch operation. However, the sign support device is complicated because the clamp mechanism is complicated. The production cost is high, and the mechanical part often fails due to dust and the like at the construction site, and there is a problem that it cannot withstand use in a bad environment such as road construction.

SUMMARY OF THE INVENTION The present invention has been developed in view of the problems encountered in the above-described conventional sign support devices for road works and the like, and provides a sign support device having a simple configuration and easy detachability. The purpose is to:

[0006]

In order to achieve the above object, a sign support device for road works or the like according to claim 1 of the present invention comprises a strip plate or a plurality of pipe guardrails laterally mounted between columns. A sign support device for road construction or the like to be mounted on a contact surface that contacts one side surface of the guardrail;
A substantially U-shaped support body is formed comprising upper and lower locking surfaces for locking the upper and lower edges of the guardrail, and the contact surface of the support is a cross-sectional shape that matches the shape of one side surface of the guardrail. A support pillar insertion hole is formed in the free end side of the upper and lower locking surfaces of the support so as to penetrate vertically, and the upper and lower support pillars are inserted with the contact surface of the support in contact with the guard rail. A support pillar for the sign is inserted into the hole from above, and the sign is vertically supported by sandwiching the front and back of the guardrail.

[0009] With the above configuration, the capping cylinder is first placed over the column of the existing guardrail from above the column.
As a result, the crown casing is held by the bolt column in a state where the mounting bolt of the guard rail screwed to the column is avoided by the split provided at the lower end. Next, the sign can be reliably supported in the longitudinal direction by inserting the support pillar of the sign from the longitudinal direction into the support pillar insertion hole provided in the crown casing.

According to a third aspect of the present invention, there is provided a sign support device for road works and the like according to the second aspect of the present invention, wherein the crown casing is divided at a lower end thereof. An eye is formed, and the split is fastened to the support by a fastening member.

[0011] With the above-described configuration, first, the crown cylinder is placed over the column of the existing guardrail from above the column.
Next, the split provided at the lower end of the crown cylinder is fastened with a fastening member, and the crown cylinder is securely fastened to the support column. By inserting the support pillar of the sign vertically into the support pillar insertion hole provided in the crown casing, the sign can be supported without falling out in the longitudinal direction.

According to a fourth aspect of the present invention, there is provided a sign support device for road works or the like according to the fourth aspect of the present invention, wherein a detachable joint hole is formed in an adjacent joint surface of a concrete lid for closing a side groove of a road. A sign support device for road works or the like to be attached to a concrete lid by using a screw rod, which is attached to the lower end of the screw rod, can be inserted into the joint hole, and is locked in the joint hole by changing the direction. Locking piece to be inserted, a seat plate to be inserted into the middle of the screw bar, a fastening body of a lid screwed to the upper screw bar of the seat plate, and a support attached to the screw bar to insert a support pillar of a sign. And a column insertion hole.

[0013] Thus, the locking piece attached to the lower end of the screw rod is inserted into the joining hole adjacent to the concrete lid for closing the side groove of the road, and the direction of the joining piece is changed by changing the direction of the locking piece. To lock the locking piece. Thereafter, a fastening body for screwing the seat plate on the middle side of the screw bar to the upper side of the screw bar is tightened from above in the direction of the concrete lid. The screw bar is now fixed vertically to the concrete lid. next,
By fixing the support pillar of the sign to the support pillar insertion hole provided at the upper end of the screw rod, the sign can be reliably supported in the vertical direction.
