Prefabricated guardrail
A prefabricated guardrail is formed by connecting a plurality of sections of guardrail bodies. The guardrail body is composed of transverse steel bars and section steel bars, and the section steel bars comprise a first embedded steel bar section, a second embedded steel bar section and a frame steel bar section which are connected. A lateral opening is formed in the bottom of the frame steel bar section, the first embedded steel bar section is located in the lateral opening, the bottom of the second embedded steel bar section is connected to the first embedded steel bar section, and the bottom of the second embedded steel bar section is also located in the lateral opening; a junction box and an embedded lamp are embedded in the guardrail body, and a pipeline communicated with the junction box and the embedded lamp is further arranged in the guardrail body. An additional guardrail is arranged at the top of the guardrail body. Compared with the prior art, the anti-collision guardrail is prefabricated in an inverted mode, a horseshoe opening is formed in the upper portion, bubbles are reduced during concrete pouring, meanwhile, the compactness during concrete pouring is improved, the top face of the guardrail adopts a steel formwork as a bottom formwork, the glossiness of concrete on the top face of the guardrail is improved, and the overall appearance quality is improved.
一种预制护栏，由多段护栏体连接而成；护栏体由横向钢筋和截面钢筋组成，其中截面钢筋包括相连接的第一预埋钢筋段、第二预埋钢筋段和框架钢筋段；框架钢筋段底部形成有侧向开口，第一预埋钢筋段位于该侧向开口内，第二预埋钢筋段底部连接于第一预埋钢筋段上，且第二预埋钢筋段底部也位于该侧向开口内；护栏体上内嵌有接线箱和嵌入式灯具，且护栏体内还设有与接线箱和嵌入式灯具相连通的管道；所述护栏体顶部设有增设护栏；与现有技术相比，防撞护栏采用倒立式预制，“马蹄口”在上方，砼浇筑时减少气泡产生，同时提高混凝土浇筑时密实度，并且护栏顶面是采用钢模板做底模，提高了护栏顶面砼的光泽度，提升整体外观质量。
