Problems solved by technology

[0003] The construction of the concrete base adopts the traditional full-section on-site pouring, which is difficult to meet the requirements of the society for this "face", and the quality of honeycomb pockmarks often occurs at the dripping eaves, the construction quality is difficult to guarantee, and the removal of the formwork is difficult. produce more or less adverse social effects
In addition, during the construction of the box girder, the installation and positioning of the embedded parts of the guardrail column has many variable factors and high risks

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0039] A construction method for a steel guardrail concrete base, the construction steps are as follows:

[0040] A. In the ground workshop, soak and clean the decorative panel mold with soapy water with high concentration. The panel of the decorative panel mold should be flat, smooth, without lines and spots, and then dry the decorative panel mold with a dry rag front;

[0041] B. Place the dried decorative panel mold on the center of the vibrating table in the ground workshop, and fix the four corners with clamps to limit the relative displacement between the decorative panel mold and the vibrating table;

[0042] C. Utilize angle steel welded decorative plate reinforcement frame tires to process the vertical decorative plate steel frame 2, the upper horizontal decorative plate steel frame 6 and the lower horizontal de...

Abstract

The invention discloses a construction method of a steel guardrail concrete base. The construction method comprises the following steps of: adopting a prefabricated decorative plate in the range of a dripping eave on the outer side of the steel guardrail concrete base, and performing field installation and positioning; and enabling the concrete base to take a finished product of the decorative plate as an external mold and performing field pouring construction. A reinforcement cage of the decorative plate is processed and manufactured by a mold of the reinforcement cage of the decorative plate, a mold plate of the decorative plate adopts a plastic mold plate, and a vibration table is used for vibrating concrete, so that the appearance of the finished product of the decorative plate can achieve a mirror effect. The installation of the finished product of the decorative plate utilizes a gun carrier provided with a three-way fine adjustment device for fine adjustment, and after the finished product of the decorative plate meets the requirements after performing recheck and inspection multiple times, the finished product of the decorative plate can be firmly welded with a pre-buried steel bar on a box girder. The construction method disclosed by the invention has the advantages of greatly improving the appearance quality of the guardrail base, reducing decoration work and high-altitude operation safety risk, realizing accurate installation and positioning of a steel guardrail pre-buried piece, realizing low construction input and having better economic benefits and social benefits.

Description

technical field [0001] The invention relates to a construction method for a bridge guardrail, in particular to a construction method for a bridge steel guardrail concrete base. Background technique [0002] With the rapid development of my country's economy, the construction of transportation infrastructure has also been developed rapidly, and the demand for roads and bridges is increasing day by day. Security guards and the "face" that is directly shown to people now mostly adopt steel-concrete structures, that is, concrete bases and steel guardrails. During its implementation, the construction quality of the concrete base is the most critical part of the overall quality of the guardrail. [0003] The construction of the concrete base adopts the traditional full-section on-site pouring, which is difficult to meet the requirements of the society for this "face", and the quality of honeycomb pockmarks often occurs at the dripping eaves, the construction quality is difficult t...
