Abstract
The invention relates to a frame type concrete guardrail device for a central separation zone, which comprises a left concrete guardrail (1), a right concrete guardrail (2), a support connecting plate (3) and a filler (4), wherein the left concrete guardrail (1) and the right concrete guardrail (2) are connected by the support connecting plate (3) arranged at intervals to form a frame structure, and the filler (4) is added into a cavity of the frame structure to form an integral structure to bear the impact force of an accident vehicle. On the premise of ensuring safety, the concrete guardrails are arranged on the left side and the right side of the central dividing strip respectively and independently bear the impact force of the accident vehicle, so that the sizes of the concrete guardrails on the left side and the right side of the central dividing strip are reduced, and the construction cost is reduced.
Description
Technical Field
The invention belongs to a road traffic safety device, and particularly relates to a frame type concrete guardrail device for a central separation zone.
Background
In order to ensure the safety of road traffic, roads such as expressways, first-level roads, urban expressways and the like need to be provided with central separation belts, guard rails are arranged at the central separation belts, the central separation belts mainly play a role in preventing accident vehicles from rushing through the central separation belts to enter opposite lanes and protecting other facilities such as mark columns in the central separation belts, and concrete central separation belt guard rails are a common form. The concrete guardrail is divided to the left and right sides to establish at present central separation area guardrail main form, and the concrete guardrail that the side was divided and is established about central separation area homoenergetic satisfies the anticollision requirement, has set up twice concrete guardrail equivalently, causes concrete material quantity big, and the cost is high.
Disclosure of Invention
The invention aims to provide a frame type concrete guardrail for a central separation belt, wherein the left and right concrete guardrails of the central separation belt are connected through a support connecting plate to form a frame structure, and fillers are added into a cavity of the frame structure to form an integral structure to bear the impact force of an accident vehicle, so that the size of the left and right concrete guardrails of the central separation belt is reduced on the premise of ensuring safety, and the construction cost is reduced.
The technical scheme of the invention is as follows:
the utility model provides a frame-type central separation area concrete barrier, includes left side concrete barrier, right side concrete barrier, supporting connection board, filler, and wherein left side concrete barrier, right side concrete barrier pass through the supporting connection board and connect and form frame construction, and left side concrete barrier, right side concrete barrier, supporting connection board can be precast concrete structure or cast in situ concrete structure respectively. The supporting connecting plates are connecting members of concrete guardrails on the left side and the right side and are arranged at intervals, and necessary holes are needed to be arranged for facilitating the arrangement of pipelines in the central separation belt. The physical dimension of the collision-facing surface of one side of the adjacent lane of the left concrete guardrail and the right concrete guardrail is in accordance with the physical dimension of the collision-facing surface of guardrails such as F-shaped guardrails, single-slope guardrails and the like required by the specification, and the inner side dimension is identical with the dimension of the support connecting plate. Concrete grades and reinforcement schemes adopted by the left concrete guardrail, the right concrete guardrail and the supporting connecting plate are determined according to different anti-collision grade requirements. The filler can be planting soil, or other building filling materials with certain compactness and difficult deformation.
The invention has the beneficial effects that:
the left concrete guardrail and the right concrete guardrail are connected through the supporting connecting plates to form a frame structure, so that the whole frame is stressed, the structural size of each component is reduced under the condition of meeting the anti-collision grade, and the manufacturing cost is reduced.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, fig. 2 and fig. 3, a frame-type central divider concrete guardrail comprises a left concrete guardrail, a right concrete guardrail, a support connecting plate and a filler; left side concrete guardrail, right side concrete guardrail, supporting connection board can adopt cast-in-place or precast concrete respectively, and left side concrete guardrail and right side concrete guardrail pass through the supporting connection board and connect and form frame construction, add the filler formation whole in this frame construction cavity, undertake accident vehicle's impact jointly. And the concrete grades and the reinforcement arrangement of the left concrete guardrail, the right concrete guardrail and the support connecting plate are calculated and determined according to different protection grade requirements. The supporting connection plates are arranged at intervals, and the distance between the supporting connection plates is determined according to the stress requirement of the whole frame. The supporting connecting plate is in a rectangular shape, a trapezoidal shape or the like with the same thickness, and necessary holes can be formed according to the arrangement requirement of the inner pipeline of the central separation belt. The reinforcing bar should be effectively connected with side concrete guardrail reinforcing bar about with when the supporting connection board adopts cast-in-place scheme, should set up connecting device and firmly connect with side concrete guardrail about with when the supporting connection board adopts prefabricated scheme. The physical dimension of the collision-facing surface of one side of the adjacent lane of the left concrete guardrail and the right concrete guardrail is identical with the physical dimension of the collision-facing surface of the guardrail such as an F-shaped guardrail, a single-slope guardrail and the like required by the specification or other physical dimension verified by adopting other advancing tests, and the size of the inner side of the guardrail is identical with that of the support connecting plate. The left concrete guardrail and the right concrete guardrail are longitudinally arranged along the route, deformation joints and longitudinal connecting components are arranged when cast-in-place is adopted, and connecting tongues and connecting components are arranged when a prefabricated scheme is adopted. The filler is preferably planting soil, can fully utilize the space of the central separation zone to plant plants to green and beautify roads, and can play an anti-dazzle role.
In order to discharge accumulated water in the central separation zone, the nonwoven geotextile, the drain pipe hole and the like can be arranged at the bottom of the filler by adopting the prior art, and the arrangement method is the prior art and is not described again.
In order to indicate the linear contour of the road and the driving direction, contour marks are respectively arranged on the outer sides of the concrete guardrails on the left side and the right side, and the contour marks are set to be in the prior art and are not repeated.
