Description

Bridge guardrail metal column base construction leveling device

technical field

The utility model relates to a leveling device, in particular to a leveling device used for the construction and leveling of the base of a metal column of a bridge guardrail.

Background technique

In recent years, with the emergence of large and medium-sized bridges, the application of metal beam-column guardrails on bridges has continued to increase. The metal beam-column guardrail structure can effectively protect out-of-control vehicles, effectively reduce the probability of the above-mentioned accidents, reduce the losses caused by accidents, improve the traffic safety level of the expressway, and can also be used as a pillar for bridge landscape lighting. It is required that the metal beam-column guardrail column should be vertical after the concrete guardrail is installed, otherwise it will be toppled or twisted under the action of wind load, and eccentric pressure will be generated under the action of its own gravity and vertical load, which will cause a relatively large section. Bending moment is not conducive to its normal use. When the wind load is large or the eccentricity is large, it may exceed the limit of the bearing capacity of the control interface and cause damage. Therefore, the vertical installation of the metal beam-column guardrail column on the bridge body has a great influence on its normal use, and whether the base of the metal beam-column guardrail column is installed horizontally is a decisive factor to ensure its vertical installation.

In order to ensure the vertical installation of the metal beam-column guardrail column of the bridge, the method of front and rear correction with a level ruler and a hanging hammer is generally used. Although this method is feasible, the operation process is cumbersome, consumes a lot of manpower, material resources, and time, and the construction speed is low. The construction cost is higher.

Utility model content

In order to solve the problem that the installation and leveling process of the metal beam-column type guardrail column of the existing bridge is cumbersome, the utility model provides a construction leveling device for the base of the bridge metal beam-column type guardrail column base.

In order to achieve the above object, the technical scheme that the utility model takes is:

A bridge guardrail metal column base construction leveling device, which is a right-angle frame formed by fixed connection of a vertical side frame and a horizontal top frame; the side frame is a closed frame, and the two sides of the side frame Leveling bolts are respectively provided at the bottom of each leg; the top frame is an open frame, that is to say, the end of the top frame is open, and a reinforcing longitudinal bar is arranged on the two cross bars of the top frame, and Two supporting claws protruding inward are respectively provided on the bottom surface of both sides of the top frame cross bar between the end of the frame and the reinforcing longitudinal bar, and the four supporting claws form a horizontal support surface; The U-shaped frame protruding from the outside. In order to ensure the stability of the right-angle frame, diagonal braces are provided on both sides of the right-angle frame.

When in use, the U-shaped frame of the utility model is lapped on the outer formwork of the concrete guardrail of the bridge body, and the leveling bolts are placed on the ground; On the horizontal support surface of the utility model leveling device, screw holes corresponding to the positions of the base screw holes are reserved on the bottom plate; adjust the right-angle frame so that the upper surface of the bottom plate is at the same height as the top of the outer formwork; place an upper level bubble on the bottom plate, Fine-tune the leveling bolts. When the level bubble is in the center, it means that the base plate is on the horizontal plane. At this time, the base plate is immediately welded to the steel frame of the concrete guardrail of the bridge body, and short steel bars cut on site with appropriate lengths are used for welding. After the bottom plate is welded, the leveling device is pulled out laterally along the bridge for the next operation. The horizontal position of the bottom plate ensures the horizontal position of the base, and the horizontal position of the base ensures the verticality of the metal columns of the bridge guardrail.

The utility model adjusts the level air bubbles placed on the bottom plate to the level through the coordinated action of the main body bracket, the U-shaped lap frame and the leveling bolts, and provides a basis for the vertical installation of the metal columns of the bridge guardrail. The utility model has the advantages of convenient raw material acquisition, simple manufacturing process, and the whole is light and convenient to move. In the actual operation process, the operation process is simple and easy to learn, and can be reused. The construction precision is high, which can effectively improve the construction speed and quality, and reduce the construction cost.
