Problems solved by technology
[0004] This structure and construction method has the following defects: 1. The concrete railing column is a solid structure with a large weight, which is not convenient for prefabrication and transportation, and it is also inconvenient for on-site construction and installation
2 After the railings are installed, the structural properties between the railing columns and the bridge, and between the columns and the barriers are poor, the installation stability and the structural strength of the railings are low, and the safety hazards are relatively large

Embodiment Construction
[0068] The present invention will be further described in detail below in combination with specific embodiments.
[0069] During specific implementation: a construction method for concrete railing columns in the middle of a bridge road is characterized in that it comprises the following steps:
[0070] 1) During the construction of the bridge pavement, pre-cast and fix several vertically upward steel bars for pouring into the interior of the column on the column installation position on the outer edge of the road on both sides of the upper surface of the bridge;
[0071] 2) Prefabricated panel components and baffles in the factory. The panel components include two panels fixedly arranged at relative intervals along the front and rear directions. The outer surfaces of the two panels are used to form the front and rear sides of the column. The distance between the two panels and the width of the baffle match;
[0072] 3) During the on-site construction of the column, first stan...

The invention discloses a bridge road middle concrete handrail stand column construction method. The method comprises the steps of 1) during bridge pavement construction, pre-pouring and fixing a plurality of reinforcing steel bars on a stand column mounting position on the upper surface of a bridge; 2) prefabricating a panel component and baffle plates in a factory in advance, wherein the panel component comprises two panels which are oppositely and fixedly arranged at an interval along the front-back direction; (3) during field construction of the stand column, covering a pre-poured reinforcing steel bar between the two panels, clamping the end parts of the baffle plates on the side surfaces of the left side and the right side of the stand column between the two panels, and defining a pouring space between the two panels; and (4) pouring concrete into the pouring space, forming a concrete inner core after the concrete is solidified, and fixing the two panels and the ends of the baffle plates on the left side face and the right side face into a whole through the concrete inner core. The construction method has the advantages that prefabrication and transportation can be facilitated, the field construction convenience degree is improved, the construction quality is improved, and the handrail installation strength is improved.
Description
technical field [0001] The invention relates to the technical field of bridge railings, in particular to a construction method for concrete railing columns in the middle of bridge roads. Background technique [0002] Usually, during bridge construction, sidewalks will be set on both sides of the bridge, and bridge railings will be set on the outer edges of the sidewalks to protect pedestrians from falling under the bridge. There are usually wooden structure railings, metal structure railings and concrete structure railings for bridge railings. Among them, concrete structure railings are widely used because of their firm structure, convenient construction, and low cost. The railing of the concrete structure is composed of a plurality of railing columns arranged at intervals, and a railing plate connected between the railing columns, wherein the railing column is a basic component for support. [0003] The existing bridge road concrete railing column structure usually includ...
