Problems solved by technology

[0008] The technical problem to be solved is: in the cantilever truss with upward pulling cables and downward pulling columns, the rods in the cantilever truss are easy to cross contact with the cables and the hanging columns, causing a series of problems. The chords of the trusses are prone to fracture due to shearing

Embodiment Construction

[0042]A connection node that avoids the intersection of the cantilever truss, the stay cable and the hanging column, and is used to connect the stay cable 1 for pulling and reinforcing the cantilever truss, and the hanging column 4 suspended under the cantilever truss to the cantilever truss to which it is connected; Among the lower chords of the cantilevered truss, the lower chord that overlaps with the projection of the upper chord in the vertical direction is denoted as the node lower chord 2 .

[0043] The cantilevered truss here protrudes from the vertical installation foundation, and is pulled and reinforced by the diagonally upward stay cable 1, and then some other loads are suspended by the hanger 4 below. In this embodiment, the hanging column 4 is an additional floor slab.

[0044] The present invention can be used for box trusses or plane trusses, and can be used anywhere on the node lower chord 2 including the ends. In the present embodiment, the detailed structur...

Abstract

The invention relates to the technical field of connection of general building structures, and discloses a connection node and a construction method for avoiding the intersection of a cantilever truss with a stay cable and a hanging column, and is used for pulling and reinforcing the stay cable of the cantilever truss and hanging it on the The hanger under the cantilever truss is connected to the box-type cantilever truss; in the present invention, by connecting the stay cable and the hanger on the lower chord of the node, the cross contact between the hanger and the rod in the cantilever truss is avoided , and then connect the cables on both sides of the lower chord in pairs, thus preventing the cross contact between the cables and the rods in the cantilever truss, avoiding affecting the transmission of forces in the cables and the suspenders, and avoiding the occurrence of damage caused by contact. rust; by connecting the stay cable and the corresponding hanger on the same node, the load transmission path is greatly simplified, and the internal force analysis of the cantilever truss becomes simple; at the same time, the shearing of the lower chord of the node is avoided.

Description

technical field [0001] The invention relates to the technical field of connection of general building structures, in particular to a connection node and a construction method for avoiding the intersection of a cantilever truss, a stay cable and a hanging column. Background technique [0002] The truss is a steel frame composed of chords and webs. Its structure has undergone rigorous force analysis, so that all materials in the truss are distributed in the position where the force is greater. Therefore, compared with solid building materials, the truss It is much lighter and can be used in buildings with very large spans. [0003] Trusses have high tensile / compressive strength in the axial direction and flexural strength in the vertical direction, so they can be used in various applications, such as beams, columns, roofs, and purlins. And because it can be connected with steel cables, steel suspension columns and other components, trusses also have prestressed cables for cab...
