Method for rapidly mounting reinforced concrete crash barrier steel form

Abstract

The invention discloses a method for rapidly mounting a reinforced concrete crash barrier steel form. The top parts of an inside form and an outside form are respectively and fixedly connected with a reinforced bar ring. The method comprises the following steps of: (1) determining the inner side line of a crash barrier and determining the mounting height of a form; (2) fixing an inner row of reinforced bars and an outer row of reinforced bars on a bridge deck within the inner side line, and welding horizontal supporting reinforced bars at the bottom and the top of the reinforced bars of the crash barrier; (3) mounting the inside form; (4) mounting the outside form, i.e. firstly inserting a horizontal steel pipe in the reinforced bar ring at the top part of the inside form, connecting a diagonal tension reinforced bars between the inner end of the horizontal steel pipe and the inner side of the inside form, lifting the outside form to the outer end of the horizontal steel pipe and adjusting the top height of all outside forms; and (5) hanging a hanging basket and mounting diagonal tension bolts of the inside form and the outside form with the hanging basket as a construction platform. The invention has simple and convenient implementation, low cost, short construction period and short time of work high above the ground, and has better economic benefits and social benefits.

Description

technical field [0001] The invention relates to a method for installing a steel formwork, in particular to a method for quickly installing a steel formwork for a reinforced concrete anti-collision guardrail. Background technique [0002] Reinforced concrete anti-collision barriers must be installed on both sides of the bridge, and the pouring of reinforced concrete anti-collision barriers for bridges needs to use large-scale steel formwork processed and finalized by the factory. At present, there are two traditional installation methods for the steel formwork of the anti-collision guardrail: (1) When the height is relatively not too high, a construction scaffolding operation platform is built on the lower side of the edge of the bridge, and the formwork installation and reinforcement work normally requires a lot of scaffolding and other materials need to be erected and dismantled manually, the construction cost is high, the operation time is long, and the requirements for th...

Problems solved by technology

At present, there are two traditional installation methods for the steel formwork of the anti-collision guardrail: (1) When the height is relatively not too high, a construction scaffolding operation platform is built on the lower side of the edge of the bridge, and the formwork installation and reinforcement work normally requires a lot of scaffolding and other materials need to be erected and dismantled manually, the construction cost is high, the operation time is long, and the requirements for the site under the bridge are relatively high; A cantilevered operation platform is formed, and the cantilevered operation platform plays two roles of the operator's work platform and the support of the weight of the steel formwork

Operators work at heights for a long time. It takes material and labor costs to set up the work platform. The construction cost is high and the construction period is long. The holes left in the bridge flange affect the appearance quality

To sum up, the current installation of steel formwork for anti-collision guardrails belongs to high-altitude operations, which is very dangerous, difficult to operate, long-term high-altitude operations, and low labor efficiency.
