Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0034] refer to Figure 1-7 , a municipal road bridge simply supported beam construction structure, comprising two adjacent ground bases 1, the upper ends of the two ground bases 1 are provided with card slots 2, and the fixed sleeves in the card slots 2 are provided with pillars 3, and the upper ends of the pillars 3 are The fixed sleeve is provided with a limit flange 4 that is offset against the floor base 1;

[0035] It should be noted:

[0036] First, by excavating square pits adjacent to 20-25m in the ground, the depth of the square pit is guaranteed to be 5-7m, and a reinforced concrete structure is established in the square pit to pre-embed and...

Abstract

The invention discloses a municipal road bridge simply supported beam construction structure which comprises two adjacent floor bases. Clamping grooves are formed in the upper ends of the two floor bases, and limiting flanges abutting against the floor bases are fixedly arranged on supporting columns in a sleeving mode. The supporting columns provided with vertical holes and piston cavities are arranged in the adjacent floor bases, the pistons and strong supporting rods which form an integrated structure are arranged in the vertical holes and the piston cavities, and the strong supporting rodsare used for supporting horizontally-arranged bearing cantilever beams; a supporting frame with an adjustable height position is arranged on the upper side wall of each supporting column in a sleeving mode, and the supporting frame and the supporting columns are connected with the bearing cantilever beams; and threaded hanging rods arranged in the arc-shaped supports are arranged at the lower ends of the bearing cantilever beams at equal intervals, and the arc-shaped supports sleeve the threaded hanging rods so that the bearing cantilever beams can be kept horizontal and stable. Mounting columns and limiting frames which jointly support a bridge deck are arranged on the bearing cantilever beams, and the limiting frames are used for righting and limiting the bridge deck so that the stability and the bearing performance of the bridge deck are guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction of municipal road bridges, in particular to a construction structure of simply supported beams of municipal road bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. With the development of the times, in order to adapt to the modern high-speed development of the transportation industry, the bridge can be extended to cross the mountains, bad geology or meet other traffic needs and erected to make traffic more convenient. Its specific performance is composed of superstructure, substructure, support and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutment, pier and foundation; the support is bridge span structure and The force transmission device installed at the supporting p...
