Description

Variable assembly shading film {A VARIABLE ASSEMBLY TYPE LIGHT BLOCKING DEVICE}

The present invention relates to a light shielding film assembled to the guard rail in a variable manner, and more specifically, regardless of the left and right width of the guard rail provided in a pair of right and left along the center line of the road, easy and quick assembly to improve work productivity, delivery date It relates to a variable prefabricated shading film improved to shorten.

In general, national roads and highways have a central line drawn at the center to distinguish between the up and down lines on which the vehicle is traveling, or a retaining wall made of a concrete structure is installed at the central part corresponding to the center line to prevent the vehicle traveling at high speed from invading the center line. Guard rail consisting of a single or left and right pair is installed.

In order to prevent the driver's vision from obstructing the driver's vision by the headlights of the vehicle during night driving, the guardrail reflects the lights of the vehicles that drive at high speed in both directions on the up and down lines of the road, thereby securing the driver's forward field of view. A plurality of light shielding films are provided at regular intervals along the guard rail.

As shown in FIG. 1 (a) (b) (c), when the light shielding film 1 is to be installed on the left and right pairs of guard rails 2 and 3, the light shielding film 1 is the guardrail. According to the width W between (2) and (3), it manufactures previously according to a pre-order, and the worker assembles the produced light shielding film 1 directly on the road site.

The light shielding film 1 includes a light shielding body 10 to which a plurality of reflecting papers 5 reflecting a headlight of a vehicle are attached, and a plurality of insert bolts 15 integrally provided at a lower end of the light shielding body 10. And upper and lower brackets 21 and 22 overlapping up and down as a plurality of fixing screws 25 so that both ends are fitted to the guard rails 2 and 3.

Accordingly, the operation of assembling the light shielding film 1 by assembling the light shielding body 10 having the reflective paper 5 attached to the entire front and rear surfaces vertically between the pair of guard rails 2 and 3 is performed by the guard. Inclined portions 21a formed at both ends of the upper and lower brackets 21 and 22 in a state in which the rails 2 and 3 are assembled to be arranged side by side with a predetermined width W on both left and right sides of the post, not shown. Position (22a) is fixed as a plurality of fixing bolts 25 and the nut portion (25a) so as to fit between the guard rail (2) (3).

At this time, the upper and lower brackets (21, 22) of the upper and lower brackets 21 and 22 are tightened to generate a fixing force to generate the upper and lower brackets (21, 22) is the guard rail (2) ( Position is fixed between 3).

In this state, since the bolt holes 23 and 24 formed in the upper surfaces of the upper and lower brackets 21 and 22 are positioned on the same vertical axis, the operator may not be able to secure the bolt holes 23 and 24. By inserting the insert bolt 15 exposed downward from the lower end of the light shielding body 10 in accordance with, and then tightening the nut member (15a), the light shielding body 10 to the upper and lower brackets (21, 22) ) Can be assembled in a vertical position.

Here, the bolt holes 23 and 24 to which the light shielding body 10 is assembled may have a predetermined angle of 15 ° with respect to the imaginary line X passing through the center of the upper and lower brackets 21 and 22 on a plane. Since the through-shape is formed to have θ), the light shielding body 10 assembled thereto is disposed to be biased to one side, thereby effectively reflecting the headlights of the vehicle so that the headlights of the vehicle do not shine to the driver.

However, when the width W of the guard rails 2 and 3 previously installed on the road is formed to be larger than the reference width W without being installed according to a preset width dimension, the length at which the worker is formed is the reference width W. When the upper and lower brackets 21 and 22 are machined to fit the upper and lower ends of the inclined portions 21a and 22a and the guard rails 2 and 3, they are small. It may not be able to secure a stable fixing force, and because of this there is a risk that the installed shading film 1 is dropped by the external force.

On the other hand, when the width W of the guard rails 2 and 3 pre-installed on the road is smaller than the preset reference width W, the formed length is machined to match the reference width W. Since it is difficult to assemble the lower brackets 21 and 22 between the guard rails 2 and 3, the work of installing the light shielding film 1 must be stopped, thereby reducing work productivity. There was a problem that the construction delivery delay.

In particular, since the width change in the guard rails 2 and 3 provided on the curved road is relatively large and irregular, unlike the straight road, the upper and lower brackets 21 integrated with the guard rails 2 and 3 of the curved road are The work of installing the light shielding film 1 having the 23 was very difficult and the work time was excessively long.

In addition, in order to quickly replace the light shielding film 1 installed on the guard rails 2 and 3, a sufficient amount of spare parts of the integrated upper and lower brackets 21 and 22 prefabricated to the reference width must be secured separately. Therefore, it is inconvenient to repair and maintain the equipment of the light shielding film 1, and the maintenance cost was excessively required.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the purpose of which is easy and quick to perform the installation work irrespective of the width change of the guard rail installed in pairs on a straight line, curved road It is to provide a variable assembly shading film that can improve the work productivity and shorten the delivery time.
