Abstract
Description
[Technical field]
[0001] The utility model belongs to the technical field of prefabricated construction of New Jersey guardrails, in particular to a back surface finishing device for plastering New Jersey guardrails. [Background technology]
[0002] New Jersey guardrail is a kind of traffic safety facility, often used as a central dividing strip as an isolation and anti-collision facility. It is often prefabricated horizontally using a standardized steel mold with the exposed surface facing downward. New Jersey (concrete) guardrail is a wall-type guardrail with a certain cross-sectional shape. Its characteristics are: when a car collides with the guardrail, under the action of the instantaneous moving load, the guardrail basically does not move or deform (rigid state). The energy during the collision is mainly absorbed by the car climbing and turning along the front of the guardrail in contact with the front of the guardrail. At the same time, the colliding car also returns to the normal driving direction. In general, New Jersey guardrail is more conducive to the climbing and turning of the colliding vehicle, and is therefore better for reducing vehicle damage and protecting the safety of the occupants.
[0003] Since the back of the guardrail is not used as the oncoming surface or anti-collision surface, the back is basically not polished, and the flatness and glossiness of the back of the guardrail are not so important.
[0004] With the development of the national economy, the highway construction industry has developed rapidly. Highway reconstruction and expansion has been and will continue to be the main direction of highway construction in my country. The requirements for traffic safety engineering design and construction are constantly increasing. The design of traffic safety needs to be closely integrated with the traffic organization plan, and full consideration should be given to the combination of permanent and temporary facilities. The prefabricated New Jersey guardrail is used in advance as a temporary facility during the maintenance period. The front and back of the New Jersey guardrail are designed according to the anti-collision surface, which plays a major role in separating oncoming vehicles. However, after the guardrail is cast, the glossiness of the front of the guardrail can be guaranteed, and the back of the guardrail usually does not need to be finished or is finished manually, and there are marks of finishing, which affects the visual beauty when isolating oncoming vehicles.
[0005] In response to the above problems, the applicant proposed a new technical solution. [Contents of the utility model]
[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a New Jersey guardrail back surface finishing device, the technical solution adopted is:
[0007] A New Jersey guardrail back surface finishing device comprises a finishing steel plate trowel suspended above the guardrail template. The finishing steel plate trowel can be adjusted up and down in height so that its bottom surface is attached to the top surface of the cast body in the guardrail template.
[0008] According to an embodiment of the utility model, a New Jersey guardrail back surface finishing device includes a truss suspended above the guardrail template, an adjusting screw is vertically provided on the truss, and the adjusting screw can be adjusted up and down in height on the truss; the finishing steel plate trowel is fixed to the bottom of the adjusting screw.
[0009] According to an embodiment of the utility model, a New Jersey guardrail back surface finishing device includes a gantry frame, the gantry frame is straddled on the guardrail template, and the truss is the top rod of the gantry frame.
