Inclined triangular pyramid truss type frame construction and method for making, mounting and measuring the same

Abstract

This invention discloses an inclined triangular pyramid trussed-beam frame, in addition to a manufacturing, installing and measuring method, characterized in that the frame comprises the bench and top center, and three ridge lines of the bench are the girders connected by several lattice pillars through flange; the pillar pin of the trussed-beam is fixed in one base station as the bottom, wherein one girders pillar is the forced pillar and has a included angle with the bottom from 90 to 110 Deg, while other two pillars are tension pillars and have the included angle with the bottom from 50 to 65 Deg; the bench also comprises several girders beam welded by lattice unit, separating to several parallel layer horizontal to the bottom between the girders pillars and connected by the flange; the lattice pillar unit is welded by several steel pipe and flange, and the lattice pillar units are connected each other through flange; the top center is an integrated structure welded by the steel pipe, and three ridge lines of the top center are the extended steel pipe along the girders pillar of the bench.

Description

technical field [0001] The invention belongs to the construction technology of tower mast structure engineering in the field of civil engineering engineering, and particularly relates to an inclined triangular pyramid-shaped steel pipe space truss frame structure leaning tower and its construction method. The structure type is a space steel structure, specifically a space truss frame structure. Background technique [0002] The towering structures at home and abroad mainly include TV towers, radio towers, microwave towers, transmission line towers, tourism, sightseeing, and memorial towers, which are mainly divided into steel structures and reinforced concrete structures (including prestressed concrete structures). Among them, the steel structure has the following advantages: high steel strength, good plasticity and toughness, homogeneous isotropic properties, weldable and assembling, good overall stability, and light overall weight. See the table below for an overview of h...

AI Technical Summary

Problems solved by technology

[0006] The linear or folded straight towers of the prior art are stable in appearance and do not have the sense of urgency and shock caused by tilting, but the construction of the leaning tower has certain technical difficulties, and its foundation and main body are processed in sections. The installation and installation have more complicated deformation control measures, which require precise factory processing positioning and on-site installation air positioning, and the existing technology has not yet proposed a mature technical solution for the construction of leaning towers
