Embodiment Construction

[0021] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0022] figure 1 The illustrated embodiment is a spliced ​​long-span steel truss installed on the top floor of a 94.1-meter-high factory building, with a span of 38 meters and a weight of 37 tons per truss. Because the original design is a rectangular truss with an overall structure, the resulting product is large in size and heavy in weight, and cannot be lifted vertically with conventional lifting equipment at the construction site. In order to overcome the difficulty of hoisting large and super-heavy components to the top floor of super-high factory buildings for installation, the overall structural scheme of long-span steel trusses was abandoned, and a spliced ​​long-span steel truss was adopted. The steel truss of this structure is in pieces before installation, so the individual components are small in size and light in weight, wh...

Abstract

The invention discloses a splitting-type large-span steel truss. The splitting-type large-span steel truss consists of inner lower strings, side lower strings, cross joints, side upper strings, web members, inner upper strings and clamping plates. The side lower strings are positioned at the two ends; the inner lower strings are positioned between the side lower strings; components are split into a lower string through joints. The side upper strings are positioned at the two ends; the inner upper strings are positioned between the side upper strings; components are split into an upper string through joints. The cross joints are arranged between the lower string and the upper string which have the same length and opposite to each other in parallel; the outwards extending joints of the cross joints are respectively butted with the lower string and the upper string. The components are split by adopting connecting and welding the clamping plates; the joint strength is high; the safety is guaranteed. The components are dispersed when the splitting-type large-span steel truss is mounted; single components are small in size and light in weight, and are convenient to hang by using a tower crane configured at a construction site; the components are mounted without lifting obstacle in a project.

Description

technical field [0001] The invention relates to a metal component of a frame structure, in particular to a steel truss, in particular to a spliced ​​large-span steel truss which is convenient for vertical lifting by a conventional tower crane equipped on a construction site. Background technique [0002] Due to the large construction area of ​​large buildings, the steel roof truss on the top floor has a large span and heavy weight. In engineering design of some buildings, taking into account the factors of natural lighting and reducing the self-weight of the top floor, steel trusses are often used as the roof beams of the top floor. It can be known from metal structure that steel trusses are a kind of light-weight structural parts. Even so, the self-weight of each large-span steel truss still weighs several tons. For example, the self-weight of a steel truss with a span of 38 meters is 37 tons. The maximum lifting capacity of the 70-meter end of the tower crane configured o...
