Description

Technical Field

[0001] The utility model belongs to the technical field of traffic facilities, and particularly relates to a combined guardrail. Background Art

[0002] Guardrails are traffic safety devices installed on the outside of roadsides, traffic dividers, and pedestrian curbs. The primary function of highway guardrails is to prevent vehicles from running off the road and to provide guidance. Experimental testing has shown that without guidance, collisions can occur on highways, increasing the likelihood of secondary collisions between the impacted vehicle and other normally traveling vehicles, resulting in more serious accidents. Therefore, the state mandates the installation of guardrails on both sides of highways to prevent these situations.

[0003] Chinese patent document CN217298732U (202221234736.1) discloses a movable guardrail with an anchor-free concrete base for highway reconstruction and expansion construction, including at least one movable guardrail unit placed on the road surface for protection, and each movable guardrail unit includes a corrugated beam guardrail, a column and a concrete base that are connected and fixed in sequence from top to bottom. Although the concrete base can be placed on the road surface to generate greater friction resistance, it can be exempted from anchoring while achieving a protective effect. However, in order to drain water, a drainage hole is provided under the concrete base, which reduces the friction between the concrete base and the ground. After being hit, it is easy to fall over or cause the guardrail to move, thereby weakening the protective effect. In addition, in order to realize the mutual connection of the concrete bases, it is necessary to overlap each other through the connection hinge ears embedded in the concrete base and the installation of connecting rods. The installation steps are complicated, which affects the installation efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a combined guardrail, which realizes the quick connection of the two adjacent concrete bases by arranging a counterweight connecting block at the connection of two adjacent concrete bases, the counterweight connecting blocks are respectively in contact with the upper end surfaces of the two concrete bases, and the columns are connected to the concrete bases through the connecting holes of the concrete bases, thereby enhancing the overall weight and center of gravity stability of the guardrail, thereby having better anti-impact ability.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: a combined guardrail comprises a concrete base, upright posts, a crossbeam and a counterweight connecting block;

[0006] A drainage hole is provided through the bottom of the concrete base;

[0007] The columns are detachably arranged on the upper ends of the concrete base in the vertical direction, and the crossbeams are detachably arranged on the upper ends of the columns in the horizontal direction;

[0008] The counterweight connection block is arranged at the connection of two adjacent concrete bases, and the counterweight connection block is in contact with the upper end surfaces of the two concrete bases respectively;

[0009] The counterweight connection block is provided with a limiting hole matching the column, and the column is connected to the concrete base through the connection hole.

[0010] The utility model preferably further comprises a connecting piece, which is arranged at the connection of two adjacent crossbeams and is detachably connected to the two adjacent crossbeams. By arranging the connecting piece to connect the two crossbeams together, it helps to enhance the integrity of the guardrail and make the guardrail have a better protective effect.

[0011] Preferably, the crossbeam is a rectangular tube or a circular tube, and the connecting piece is a hollow tube with the same shape as the crossbeam;

[0013] The ends of two adjacent crossbeams are spaced apart from each other, and the connector is sleeved over the ends of the two adjacent crossbeams. The connector and crossbeam are mounted above a first support connecting plate, and the connector, crossbeam, and first support connecting plate are connected by fasteners. The crossbeams are made of rectangular or circular tubes, and the connector is configured as a hollow tube with the same shape as the crossbeam. This allows the connector to be sleeved over the ends of the two adjacent crossbeams, and the connector, crossbeam, and first support connecting plate are quickly connected by fasteners, thereby enhancing the strength of the connection between the two crossbeams and facilitating assembly.

[0014] Preferably, the cross section of the beam is groove-shaped or H-shaped, and the connecting member is plate-shaped;

[0015] The crossbeam is provided with a groove matching the diameter of the column, and the groove is arranged along the axial direction of the crossbeam;

[0018] The second support connecting plate is positioned within the groove and contacts the bottom of the groove. The connector, beam, and second support connecting plate are connected via fasteners. Since the cross-section of the beam is groove-shaped or H-shaped and the connector is plate-shaped, placing the two ends of the connector on the ends of the two beams allows the connector, beam, and first support connecting plate to be directly connected via fasteners, achieving a quick connection between the two beam ends and enhancing the strength of the connection. Inserting the column into the groove so that the second support connecting plate contacts the bottom of the groove further increases the strength of the connection between the column and beam.

[0019] Preferably, the crossbeam is corrugated, and the two ends of the crossbeam are staggered and stacked together and connected by fasteners;

[0022] The counterweight connection block is connected to two or more columns. By providing at least two columns on the concrete base, the counterweight connection block can achieve the function of connecting the two concrete bases. Connecting the counterweight connection block to two or more columns can enhance the connection strength of the two concrete joints and improve the protective effect.

[0023] Preferably, the concrete base is provided with at least one drainage hole along the axial direction of the present invention. When the drainage volume needs to be increased, a drainage hole can be provided along the axial direction of the concrete base. To enhance the protective effect, multiple drainage holes spaced apart from each other can be provided along the axial direction of the concrete base to ensure uniform drainage while increasing the contact area between the concrete base and the ground, thereby enhancing the stability of the guardrail.

[0024] Preferably, the concrete base is provided with a first insertion hole matching the column, the first insertion hole is provided through the upper and lower parts, and the concrete base is horizontally provided with a mounting hole communicating with the first insertion hole;

[0025] The column is provided with a matching hole that matches the mounting hole, and the mounting hole and the matching hole are connected by a fastener. By inserting the column into the first insertion hole and connecting the mounting hole and the matching hole with the fastener, the column is connected to the concrete base, which helps to enhance the overall strength of the guardrail.

[0026] Preferably, the concrete base is provided with a second insertion hole matching the column, and the lower end of the second insertion hole does not penetrate;

[0027] The lower end of the column is directly inserted into the second insertion hole. By providing the second insertion hole with a non-through lower end on the concrete base, the column can be directly inserted into the second insertion hole, which can also play a protective role and improve installation efficiency.

[0028] The utility model is preferred that the cross section of the column is circular, rectangular, H-shaped or groove-shaped. According to needs, the cross section of the column can be set to circular, rectangular, H-shaped or groove-shaped.
