Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figures 1 and 2, a wave form roof beam guardrail convenient to increase, including stand 1, prevent hindering piece 2 and wave form beam slab 3, seted up mounting hole 11 on the stand 1, mounting hole 11 has a plurality ofly along the axial distribution of stand 1, and a plurality of mounting holes 11 communicate each other and form even hole, and the distance of the crossing department of overlapping of two mounting holes 11 is less than the diameter of mounting hole 11. The mounting holes 11 are round holes with the diameter of 18mm, and the width of the intersection of the two mounting holes 11 is 15 mm.
The mounting holes 11 are arranged to be connecting holes, so that the distance between every two adjacent mounting holes 11 is reduced, and the adjustable precision of the corrugated beam plate 3 is improved; meanwhile, the joint between the adjacent mounting holes 11 is small, so that the mounting bolt 4 can be clamped and limited, and the block 2 is prevented from moving.
As shown in fig. 2, the distance from the mounting hole 11 at the highest position to the mounting hole 11 at the lowest position is 50 mm; because the distance between the top of the obstruction block 2 and the top of the upright post 1 is limited and is usually 50mm, the maximum distance of the mounting hole 11 is set to be 50mm, the rising height of the obstruction block 2 is improved to the maximum extent, the obstruction block 2 is prevented from protruding above the upright post 1, and the sufficient impact resistance of the obstruction block 2 is ensured.
As shown in fig. 1, a mounting bolt 4 connected with the block 2 is arranged in the mounting hole 11 in a penetrating manner, the mounting hole 11 penetrates through the upright post 1, the mounting bolt 4 penetrates through the mounting hole 11 and extends into one end of the block 2, an installation nut 41 is sleeved on the threaded sleeve, and the installation nut 41 is tightly abutted to the block 2.
As shown in fig. 1 and 3, the corrugated beam plate 3 is fixedly arranged on the anti-blocking block 2, the height of the anti-blocking block 2 is 200mm, the side wall of the anti-blocking block 2, which is far away from the upright post 1, is provided with three connecting holes 21, the connecting holes 21 are distributed along the vertical direction, and the distance between two adjacent connecting holes 21 is 50 mm. The corrugated beam plate 3 is provided with a connecting through hole 31, and a connecting bolt 5 for fixing the corrugated beam plate 3 penetrates through the connecting through hole 31 and the connecting hole 21; the connecting nut 51 is sleeved on one end, extending into the anti-blocking block 2, of the connecting bolt 5 in a threaded manner, and the connecting nut 51 is tightly abutted to the anti-blocking block 2. The plurality of connecting holes 21 can further improve the height of the corrugated beam plate 3.
As shown in fig. 1 and 3, the connection hole 21 is an elliptical hole, and the length of the connection hole 21 in the horizontal direction of the resistance block 2 is greater than the length in the vertical direction; set up connecting hole 21 into oval hole, when installation connecting bolt 5, can suitably adjust connecting bolt 5 position as required, avoid having the error and lead to connecting bolt 5 can not install, improve the practicality.
As shown in fig. 1 and 4, an arc-shaped plate 22 attached to the upright post 1 is arranged on one side of the anti-blocking block 2 away from the corrugated beam plate 3; the arc-shaped plate 22 is attached to the upright post 1, so that the contact area between the arc-shaped plate and the upright post 1 is increased, and the impact resistance of the anti-blocking block 2 is increased.
This application is mainly solved from the source and adds the back because of the road surface overhaul, because of the high unnormal requirement of guardrail, and need demolish the problem of reinstallating. In actual road surface overhaul projects, a single-layer asphalt is generally paved on a road surface for 3-5 cm, or a double-layer asphalt is paved for 7-10 cm, and the adjustable maximum height is generally 10 cm. This application is through when the wave form roof beam guardrail leaves the factory, sets up a plurality of connecting holes 21 in the prefabrication in stand 1 and anti-stop block 2, and when the road surface adds the shop back, when the unsatisfied standard requirement of guardrail installation high end, through pulling down existing wave form roof beam board 3 after, confirm the road surface and add shop back mounting height, directly reinstallate. This application has solved traditional guardrail effectively and need wholly demolish, the construction is complicated, the cost is high, influence road bed safety scheduling problem after the road surface adds the shop.
In addition, this scheme just carries out prefabricated multihole according to the design when dispatching from the factory from wave form roof beam guardrail. After the road surface is heightened, the adjustment is carried out according to the requirement, any component is not replaced, any additional cost is not required to be added, and the cost is reduced.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
