Problems solved by technology

[0002] In the construction process of urban municipal roads, due to the many parallel intersections of the roads in the old city, pedestrians, non-motor vehicles and motor vehicles are mixed, which is very easy to cause congestion, especially in the process of elevated construction, it will be necessary to align beams Concrete, piers, foundations, etc. are gradually poured, and the construction period is long, which has a great impact on road traffic

Embodiment 1

[0039] The invention discloses a temporary concrete steel structure bridge for municipal construction, referring to figure 1 , including the bottom surface 3 located at the ground floor, the bottom surface 3 is the original ground floor road surface, and also includes several prefabricated road slabs 1, steel structure skeletons 2 are arranged on both sides below the road slab 1, and the steel structures on both sides A passageway 4 for pedestrians and vehicles is formed between the skeletons 2, and the adjacent road slabs 1 are connected end to end, and a fastening device is provided between the adjacent road slabs 1 to fix the two road slabs 1, so that A plurality of road slabs 1 are tightly connected and fixed to form a road surface for vehicles above the bottom surface 3 .

[0040] refer to figure 1 , in order to enhance the supporting effect of the whole structure, the steel structure skeleton 2 is hollow, after the road slab 1 is installed and fixed, fill the steel skelet...

Embodiment 2

[0047] The invention also discloses a method for installing a temporary concrete-steel structure bridge for municipal construction, the steps of which include:

[0048] S1: Fix the PTFE sliding plate 31 on the bottom surface 3, and implant the anchoring steel bar 32 on the bottom surface 3;

[0049] S2: Complete the prefabrication of the road slab 1 in the prefabrication factory, and transport it to the construction site;

[0050] S3: Install the socket 22 and the socket 23 of the adjacent road slab 1 correspondingly, and pass the steel rope into the prestressed through hole 25, and symmetrically set the two ends of each steel rope on both sides of the road slab 1 through the center jack;

[0051] S4: After every 3-4 sections of road slab 1 are installed, the entire row of through-hole jacks exert force at the same time to tension the steel rope and tighten the newly installed road slab 1;

[0052] S5: after the installation of the road slabs 1 is completed, the filler 21 ma...

Abstract

The invention discloses a municipal construction temporary concrete steel structure bridge and a mounting method thereof, and relates to the technical field of municipal construction. The invention aims at providing a temporarily-erected overpass bridge which is short in construction period and can effectively relieve traffic congestion. The bridge is characterized by comprising a plurality of prefabricated road boards, steel structure frameworks are arranged below the two sides of a base board, a passage port for pedestrians and vehicles to pass through is formed between the two steel structure frameworks, the adjacent road boards are connected end to end, a fastening device is arranged between every two adjacent road boards, and the road boards form a road surface for the vehicles to pass through.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a temporary concrete steel structure bridge for municipal construction and an installation method thereof. Background technique [0002] In the construction process of urban municipal roads, due to the many parallel intersections of the roads in the old city, pedestrians, non-motor vehicles and motor vehicles are mixed, which is very easy to cause congestion, especially in the process of elevated construction, it will be necessary to align beams Concrete, piers, foundations, etc. are gradually poured, and the construction period is long, which has a great impact on road traffic. [0003] Therefore, if a temporary viaduct that can be completed quickly can be built before the completion of viaduct construction, the traffic jam situation will be effectively alleviated. Contents of the invention [0004] The object of the present invention is to provide a temporary ...
