Lead interlayer aluminum alloy replaceable coupling beam and construction method
The invention relates to a lead interlayer aluminum alloy replaceable coupling beam and a construction method. The lead interlayer aluminum alloy replaceable coupling beam structurally comprises at least one set of replaceable energy dissipation beams and non-energy-dissipation beams arranged at the two ends of the replaceable energy dissipation beams; each set of replaceable energy dissipation beams comprises an upper chord, a web and a lower chord, and the two ends of the upper chord and the two ends of the lower chord are detachably connected with the non-energy-dissipation beams respectively; and each web of each set of replaceable energy dissipation beams comprises two aluminum alloy plates and a lead interlayer, the upper edges of the aluminum alloy plates are detachably connected with the upper chords of the same set of replaceable energy dissipation beams, the lower edges of the aluminum alloy plates are detachably connected with the lower chords of the same set of replaceableenergy dissipation beams, a gap exists between the two aluminum alloy plates of the same set of replaceable energy dissipation beams, and the lead interlayer is arranged in the gap. By means of the low yield point of the aluminum alloy, it is guaranteed that the replaceable energy dissipation beams firstly get into yield under the earthquake action, the replaceable energy dissipation beams dissipate energy under the earthquake action by means of the good energy dissipation characteristics of the aluminum alloy and lead, and the purposes that the replaceable energy dissipation beams are convenient to disassemble, transport and replace rapidly after an earthquake are achieved.
本发明涉及铅夹层铝合金可更换连梁及施工方法，该结构包括至少一组可更换耗能梁和设置于可更换耗能梁两端的非耗能梁；每组可更换耗能梁均包括上弦杆、腹板和下弦杆，上、下弦杆两端分别与非耗能梁可拆卸连接；各组可更换耗能梁的腹板均包括两块铝合金板和铅夹层，铝合金板的上沿与同组可更换耗能梁的上弦杆可拆卸连接，下沿与同组可更换耗能梁的下弦杆可拆卸连接，同组可更换耗能梁的两块铝合金板之间存在空隙，铅夹层设置在空隙内。本发明利用铝合金较低的屈服点，保证可更换耗能梁在地震作用下首先进入屈服，利用铝合金及铅良好的耗能特性，令可更换耗能梁在地震作用下耗散能量，实现了可更换耗能梁震后便捷拆卸运输、快速更换的目标。
