Abstract

The invention discloses a prefabricated fast-mounted lattice beam system and a construction method thereof. The prefabricated fast-mounted lattice beam system is formed by combining and connecting first modules and / or second modules. The adjacent modules are connected through post-poured concrete sections. Each first module comprises a reinforced concrete longitudinal beam, first joints symmetrically arranged on the two side faces of a beam body of the longitudinal beam and holes used for allowing anchor rods to pass through, wherein steel bars in the first joints extend out of concrete; the holes are located in the intersections of the first joints and the longitudinal beam and are perpendicularly formed in the beam body of the longitudinal beam in a through mode. Each second module comprises a cross-shaped reinforced concrete prefabricated part, a hole formed in the center position of the cross-shaped reinforced concrete prefabricated part and second joints arranged at the four endsof the prefabricated part, and steel bars in the second joints extend out of concrete. The prefabricated fast-mounted lattice beam system is high in assembly speed, convenient to construct and high inefficiency. During site construction, the first modules, the second modules and third modules can be combined flexibly and arranged as required.

Description

technical field [0001] The invention relates to the technical field of support construction, in particular to a prefabricated quick-installation lattice beam system and a construction method thereof. Background technique [0002] There are not many plain areas in our country. Most of the civil engineering construction is now completed in mountains, plateaus, hills and other places. During the construction process, there will be situations such as mountain excavation and grading. At present, in order to ensure the safety of construction and use, support measures must be taken for the slope. When traditional building slopes, road and railway slopes are supported by lattice beams, cast-in-place reinforced concrete is generally used. [0003] However, there are many problems in the use of cast-in-place construction: first, when the terrain is changeable, the construction is difficult, and it is impossible to properly handle each intersection, and the overall quality of the latt...
