Embodiment Construction

[0031] This embodiment focuses on the structural features and functions involved in the present invention, and is described in detail as follows in conjunction with the accompanying drawings:

[0032] figure 1 It is an elevation view of a light-duty composite girder bridge assembled with section steel and reinforced concrete slabs. Such as figure 1 As shown, the light-duty composite girder bridge assembled with section steel and reinforced concrete slab is mainly composed of prefabricated reinforced concrete slab 1, section steel beam 2, and prefabricated pier column 3. The prefabricated pier column 3 serves as the permanent support of the prefabricated reinforced concrete slab 1 and the shaped steel beam 2 , and the shaped steel beam 2 is arranged under the prefabricated reinforced concrete slab 1 , and is fixed with the prefabricated pier column 3 through the bridge support 4 . Figure 8 It is the assembly diagram of steel beams, such as Figure 8 As shown, the shaped s...

Abstract

The invention discloses a profile steel and reinforced concrete slab assembled light composite beam bridge and a construction method thereof. The composite beam bridge is mainly composed of precast reinforced concrete slabs, profile steel beams, precast pier columns and a pavement structure layer, wherein the profile steel beams are connected through high-strength bolts and are combined with welded seams to be reinforced; reserved ribs are preset in the precast reinforced concrete slabs, the precast reinforced concrete slabs are welded and connected by adopting straight thread sleeves and the reserved ribs, and the precast reinforced concrete slabs are connected with the profile steel beams through pegs, the reserved ribs and micro-expansion concrete; the profile steel beams are fixedly connected with the precast pier columns. The composite beam bridge disclosed by the invention is convenient in construction, short in construction period, high in structure safety coefficient; and according to the invention, the construction problem of a high-altitude composite beam bridge is solved effectively.

Description

technical field [0001] The invention relates to the installation of a composite girder bridge, in particular to a lightweight composite beam bridge assembled with section steel and reinforced concrete slabs and a construction method thereof. Background technique [0002] When the expressway needs to cross the river, due to the large span of the bridge, in order to ensure the stability of the structure, people use the composite beam bridge of section steel and concrete. This type of structure has problems such as heavy weight, difficult construction, and difficulty in ensuring connection strength. [0003] The traditional construction method of this type of composite girder bridge is to adjust the section steel to a high altitude and then install it. After the installation is completed, the formwork is cast and the reinforced concrete slab is poured. The pouring is difficult, not only the construction is difficult, the safety is difficult to guarantee, but also the construct...
