Problems solved by technology
In conventional construction, the installation of the steel skeleton needs to be positioned by welding and positioning steel bars, which not only increases the amount of construction work, but also prolongs the construction period
The middle steel bar is positioned by hanging wires, but the middle steel bar needs to be bound to the steel frame at the same time as the middle steel bar is positioned, which increases the difficulty of installing the middle steel bar

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] Such as Figure 1 to Figure 4 As shown, the bridge guardrail reinforcing bar positioning device in this specific embodiment includes side brackets 1 opposite and spaced apart along the left and right directions. The side brackets 1 are vertically arranged. A connecting bracket 2 is arranged between the two side brackets 1. The brackets 2 are respectively fixedly connected to the two side brackets 1, and the outer surfaces of the two side brackets 1 are respectively provided with longitudinal positioning devices, and the two longitudinal positioning devices are symmetrically arranged along the left and right directions, and the longitudinal positioning devices include vertical positioning devices installed at intervals along the vertical direction. There are a plurality of longitudinal support conduits 3 on the side bracket 1, and the longitudinal suppo...

The invention discloses a steel bar positioning device for a bridge guardrail, which comprises side brackets arranged at intervals, a connecting bracket is arranged between the two side brackets, the connecting brackets are respectively fixedly connected with the two side brackets, and the outer surfaces of the two side brackets are respectively A longitudinal positioning device is provided, and the longitudinal positioning device includes vertical positioning rods installed on the side brackets at vertical intervals for supporting the intermediate steel bars, and horizontal positioning rods arranged at intervals along the relative directions of the two side brackets on the connecting bracket, and the horizontal positioning rods A bead is arranged on the position-limiting portion of the positioning rod for limiting the steel frame, and the bead can be pressed on the lateral positioning rod through the pull rod and the tension spring, and is used to clamp the steel frame between the bead and the lateral positioning rod. The invention has the advantages of simple structure, simple and convenient operation, can conveniently locate the steel bar skeleton and the middle steel bar at the same time, and improves the construction efficiency.
Description
technical field [0001] The invention relates to the field of guardrail reinforcement installation, in particular to a bridge guardrail reinforcement positioning device. Background technique [0002] In recent years, with the continuous development of my country's economic construction and the gradual improvement of the expressway network, the protection requirements for bridges are getting higher and higher, and it is also an important link to ensure road safety. In order to ensure the smoothness and efficiency of road operation and improve the comfort and safety of road driving, it is necessary to improve the construction technology of the bridge anti-collision guardrail, improve the firmness and quality of the guardrail, and give full play to its due role. The anti-collision barriers of expressway bridges mostly adopt reinforced concrete structures. During the installation and construction of steel bars, not only the left and right equidistant spacing of the steel bar skel...
