Embodiment Construction

[0011] The present invention will be described in detail below with reference to the accompanying drawings. figure 1 . An arch rib of a reinforced concrete arch bridge includes an arch rib body 3, and a thrust conversion support is provided on the position where the arch rib body 3 and the arch rib bracket 5 are correspondingly installed. The thrust conversion support includes a pre-embedded steel bar 1 and a bottom plate 2. The lower end surface of the bottom plate 2 is a horizontal plane. The bottom plate 2 is round, square or polygonal, and its thickness is set between 10mm-100mm; the included angle between the bottom plate 2 and the arch rib body 1 is the folder horn. The diameter of the embedded steel bar 1 is set between 20mm-60mm. The total number of embedded steel bars 1 is designed according to its diameter. The larger the diameter is, the fewer the embedded steel bars 1 are.

[0012] It is used for the installation support of the arch rib of a reinforced concr...

Abstract

The invention discloses an arch rib of a reinforced concrete arch rib, an erection support and a manufacture method of the arch rib. The manufacture method can be applied to manufacture and erection of the arch rib of conventional reinforced concrete bridge and the arch rib of a reinforced concrete tied-arch bridge, and can improve the stability of an arch rib support during erecting the arch rib and after erecting and positioning the arch rib, as well as ensuring the safety in erecting of the arch rib. The arch rib disclosed by the invention comprises an arch rib body; a thrust switching support saddle is arranged in a position, corresponding to the arch rib support, of the arch rib body. The erection support is provided with an I-shaped support body, and the upper end surface of the erection support is a horizontal plane; and the support body is welded at the top part of the arch rib support and is in horizontal contact with a bottom plate of the thrust switching support saddle. The manufacture method of the arch rib comprises the following steps in sequence: pouring concrete in positions, corresponding to the arch rib support, at two ends of the arch rib body in order to fix embedded steel bars; marking a vertical line which is only formed after the arch rib main body is erected on the arch rib body before the erection is carried out; and welding the bottom plate with the lower ends of the embedded steel bars. By adopting the manufacture method, the safety in construction can be improved, and the risk in construction can be avoided.

Description

technical field [0001] The invention relates to an arch rib of a reinforced concrete arch bridge and a manufacturing method thereof, in particular to an arch rib of a reinforced concrete arch bridge and a mounting support and a manufacturing method thereof, which can be used in the manufacture and manufacture of an arch rib of an ordinary reinforced concrete arch bridge and an arch rib of a reinforced concrete tie rod arch bridge Installation, improve the stability of the arch rib support during and after the installation of the arch rib, and ensure the safety of the arch rib installation. Background technique [0002] Ordinary reinforced concrete arch bridges and reinforced concrete tied arch bridges are both types of reinforced concrete arch bridges. At present, during the installation and construction process of the arch ribs of reinforced concrete arch bridges and arch ribs of reinforced concrete tie rod arch bridges, the butt joint installation of arch ribs and arch rib...
