Embodiment Construction

[0014] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0015] Such as figure 1 figure 2 A spherical steel structure assembled tire frame with internal multi-directional bolt holes connected with high precision is shown, including end support pier 1, top connecting angle steel 2 and ring flange 3.

[0016] The end support piers 1 are arranged on the ground at the same height, and the end support piers 1 have several arranged to form a pair of mutually symmetrical arc structures and the arc structures are located on the same circle. The four ends of the symmetrically arranged arc structures The intersection of the crossing lines at the corners is the center of the spherical steel structure; the ring flange 3 has two and the two ends of the ring flange are vertically connected to the end support pier 1 on the same side.

Abstract

The invention relates to a high-precision connection spherical steel structure assembly jig frame with internal multi-directional bolt holes, being characterized in that: the jig frame comprises an end face supporting pier, a top connecting angle steel and an annular flange; and the assembly jig frame of the invention determines the position and height requirements of the longitudinal angle steelcolumns according to the spherical size positioning, strengthens the strength between each longitudinal angle steel group through the connection of the transverse angle steel and the top connecting angle steel, modularizes the installation and construction of the jig, and greatly improves the assembling efficiency of the connecting spherical steel structure.

Description

technical field [0001] The invention relates to the field of assembled tire frames, in particular to an assembled tire frame with internal multi-directional bolt holes connected with spherical steel structures with high precision. Background technique [0002] In the manufacture of bridges, in order to ensure the matching between segments and the smooth connection of bridge positions, large segments should be assembled in a continuous matching manner; comprehensively considering various factors such as construction period, assembly plan and technology, the assembly of hemispherical blocks requires It is completed on the large-shaped special assembled tire frame. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spherical steel structure assembled tire frame with internal multi-directional bolt holes with high precision connection, which can solve the problems of low modularity and low assembly efficiency of the g...
