Description

Technical Field

[0001] The utility model belongs to the field of traffic safety protection, and in particular relates to a light-weight and high-strength corrugated beam guardrail structure for a central dividing strip. Background Art

[0002] A corrugated steel guardrail is a continuous structure composed of interconnected corrugated steel panels supported by columns. It utilizes deformation in the foundation, columns, and beams to absorb collision energy, forcing the out-of-control vehicle to change direction and return to normal travel, thereby reducing damage caused by the accident. Due to its advantages such as good perspective, aesthetics, and simple structure, it is widely used in transportation facilities such as roads, railways, bridges, and tunnels. However, traditional corrugated steel guardrails have disadvantages such as high steel consumption, heavy weight, inconvenient installation, high cost, and a lack of pre-maintenance and retrofit upgrade capabilities. This has led to a search for more advantageous guardrails, and the increasing use of high-strength steel lightweight corrugated steel guardrails has become a market trend.

[0003] Based on the above situation, a lightweight and high-strength corrugated beam guardrail structure for the central dividing strip is proposed. By improving the strength grade and related properties of steel materials and reducing the weight of the guardrail material, energy saving, consumption reduction and cost reduction can be achieved. The structural design has pre-maintenance and transformation and upgrading functions, which is beneficial to later maintenance and reduces maintenance costs. It has broad market application prospects. Utility Model Content

[0004] The purpose of the utility model is to provide a light-weight and high-strength corrugated beam guardrail structure for a central dividing strip, so as to solve the problems of large steel volume of the corrugated beam guardrail and lack of pre-maintenance and transformation and upgrading functions.

[0005] In order to achieve the above technical purpose, the technical solution of the utility model is implemented as follows:

[0006] A lightweight, high-strength corrugated beam guardrail structure for a central median includes three corrugated beams, columns, and transverse connectors. The three corrugated beams on either side are anchored to the columns via transverse connectors. The transverse connectors are symmetrical and align with the grooves of the three corrugated beams on either side for bolting. The columns are bolted to the pipes of the transverse connectors and anchored to the road surface at intervals.

[0007] Furthermore, the transverse connecting member is divided into a folded plate type anti-obstruction block and a straight plate type anti-obstruction block. When the transverse connecting member is a folded plate type anti-obstruction block, it is composed of two front parts welded with pipes. The front part of the folded plate type anti-obstruction block is composed of two upper and lower straight surfaces with shorter lengths, a straight plate with longer length in the middle, and two upper and lower flat plates bent. A transverse oblong hole is provided on the straight plate. The top-view cross-sectional shape of the flat plate is a trapezoid with a narrow front and a wide back, or a rectangle with the same width in the front and back. The position of the front part is higher than the position of the pipe in vertical height. When the transverse connecting member is a straight plate type anti-obstruction block, it is formed by bending the front plate, the web plate, and the top plate. The front plate of the straight plate type anti-obstruction block is provided with a transverse oblong hole for bolting to the three corrugated beam plates on both sides. The web plate of the straight plate type anti-obstruction block is provided with multiple transverse oblong holes for bolting to the columns.

[0008] Furthermore, the column is a square tube or a round tube. When the column is a round tube, the tube of the transverse connector is also a round tube, and the tube is provided with 6 round holes, which is bolted to the column; when the column is a square tube, the tube of the transverse connector is also a square tube, and the tube is provided with 6 round holes, which is bolted to the column.

[0009] Furthermore, the two flat plates are arranged parallel to the upper and lower sides of the pipe.

[0010] Furthermore, the columns are installed by means of piling, flanges, embedding in concrete, or pre-embedded sleeves.

[0011] Furthermore, the three-corrugated beam plate, columns, and transverse connectors are made of one of ordinary carbon steel, alloy steel, and weathering steel.

[0012] After adopting the above technical solution, the utility model has the following beneficial effects:

[0013] (1) Under the premise of ensuring safety performance, compared with other steel guardrails with the same anti-collision grade, the steel consumption is low, the cost is lower, and the installation efficiency is higher;

[0014] (2) It has pre-maintenance and renovation and upgrading functions, which is conducive to later maintenance;

[0015] (3) It has a high safety reserve, meets the protection level requirements, and better maintains the safety of highway operations. BRIEF DESCRIPTION OF THE DRAWINGS
