Embodiment Construction

[0033] Next, the technical solutions in the embodiments of the present invention will be described in connection with the drawings of the embodiments of the present invention, and it is understood that the described embodiments are merely the embodiments of the present invention, not all of the embodiments.

[0034] Refer Figure 1-7 A municipal road construction bridge simply supported beam structure, including two adjacent floor base 1, two upper floor base 1 defines a slot 2, slot 2 and the fixing sleeve 3 is provided with struts, the strut 3 fixing sleeve 1 against the base floor is provided with a stop flange 4;

[0035] It should be noted:

[0036] First, by excavating in the ground adjacent the side of the pit from 20-25m, to ensure that the pit depth direction 5-7m, reinforced concrete structure by establishing side pit to be embedded on a fixed floor base 1, to ensure that the floor a base connected to ground and firmness;

[0037] Second, the package 1 on the base floor c...

Abstract

The invention discloses a simple-supported beam construction structure of a municipal road bridge, which comprises two adjacent ground bases, the upper ends of the two ground bases are provided with card slots, and the fixed sleeves on the pillars are provided with limiting flanges that offset the ground bases . In the present invention, a pillar with a vertical hole and a piston cavity is arranged in the adjacent ground base, and a piston and a strong strut of an integrated structure are arranged in the vertical hole and the piston cavity, and the strong strut is used to support the horizontally arranged load-bearing suspension beam; The height-adjustable support frame installed on the upper side wall of the pillar is installed, and the support frame is connected with the pillar and the load-bearing suspension beam; The threaded suspension rod is set on the arc-shaped bracket to maintain the horizontal stability of the load-bearing suspension beam; the installation column and the limit frame that jointly support the bridge deck are set on the load-bearing suspension beam, and the bridge deck is righted and limited by the limit frame , to ensure the stability and load-bearing performance of the bridge deck.

Description

Technical field [0001] The present invention relates to the field of municipal roads and bridges construction, in particular, to the construction of municipal roads and bridges structure of a simply supported beam. Background technique [0002] Bridges, rivers, lakes, generally refers erected in the sea, enabling smooth passage of vehicles and pedestrians and other structures. With the development of the times, in order to adapt to the rapid development of modern transportation industry, it can be extended to a bridge across the mountain, poor geological or to meet other transportation needs to make the passage easier to set up a building. The specific performance of the upper structure, substructure, support and ancillary structures composed of the upper structure, also known as bridge span structure, is the main structure spans barriers; substructure, including abutments, piers and foundation; and support for the bridge span structure force transmission device or support pier a...
