Embodiment Construction

[0049] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] Such as Figure 1-22 As shown, the new post-earthquake easy-to-repair steel special-shaped column frame-central support frame includes double-channel steel beam 1, equal-leg angle steel 2, beam-column connecting plate 3, beam end web 4, channel steel 5, steel cable 6, L-shaped special-shaped column 7, T-shaped special-shaped column 8, cross-shaped special-shaped column 9, cover plate 10, anti-buckling plate 11, reinforcement plate 12, shear plate 13, stiffening rib 14, fixed angle steel 15, connecting plate 16, diagonal brace 17. Cantilever rod I18, cantilever rod II19.

[0051] as attached figure 1 As shown, the beam of the present invention is a double-channel steel beam 1 made of section steel, and the double-channel steel beam 1 is formed by splicing the channel steel with the beam end web 4 at the beam end.

[0052] as attached figure 2 As shown, the...

Abstract

Provided is a novel post-earthquake easy-to-repair steel irregular column- center support. Double-channel steel beams are connected with irregular columns through beam end sealing plates to form a welding-gap-free full-bolt connection mode. Prestress steel cables are applied to welding-gap-free full-bolt nodes to form prestress self-resetting nodes. Axial and horizontal stress performance of the bottoms of the columns are optimized through reinforcing plates by self-resetting column legs and prestress column legs, bending-proof steel plates are mainly used for dissipating earthquake energy, and shearing plates are used for preventing shearing force from being too large and leading to local bending of the bottoms of the columns. Key members of the prestress column legs are prestress pull rods which are used for providing prestress for the columns to enable the columns to be closely connected with the beams, the column legs can be in rigid connection similarly when the torque borne by the column legs is small, and a post-earthquake self-resetting capability is achieved. By means of the center support, the structure achieves better side shock resistance.

Description

technical field [0001] The invention relates to an easy-to-repair steel special-shaped column-central support frame, which belongs to the technical field of earthquake resistance and disaster reduction, and in particular to a novel post-earthquake easy-to-repair steel special-shaped column-central support frame. Background technique [0002] The collapse of buildings in earthquakes is the main reason that threatens people's lives and causes property losses. The earthquakes in Wenchuan and Ya’an showed that the seismic performance of concrete structures is not good. At present, my country’s steel structures are developing rapidly, especially the prestressed steel structure technology is at the international advanced level. The world record for the largest structural span leads the development of prestressed steel structures. Making full use of the advantages of prestressing technology and applying it to the steel frame joints will improve the seismic performance and self-rese...
