Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Referring to Fig. 1, the double flute being conveniently replaceable is arranged among the steel skirt beam 1 of traditional steel tube fr peripheral frame in the present invention
Steel section active beam link 2 is mainly used between steel skirt beam and the connection of replaceable double flute steel shearing-type energy-consumption beam section.
Referring to fig. 2 to Fig. 5, double replaceable active beam links of channel cross-section-steel skirt beam connection structure, including two and steel framework cylinder
The steel skirt beam 1 that external surrounding frame barrel mast 8 is welded to connect, two steel skirt beams 1 are oppositely arranged, the web of two steel skirt beams 1 respectively with energy consumption
2 both ends of beam section are attached, and the both ends of the web insertion active beam link 2 of two steel skirt beams 1, active beam link 2 passes through several first
Bolt 5 is fixed on the web of steel skirt beam 1, and skirt beam securing plate 3, dissipative links are provided between active beam link 2 and the web of steel skirt beam 1
First bolt 5 being provided with active beam link securing plate 4 at conjunction in section 2.
Referring to Figure 10, the channel steel of active beam link 2 including two back-to-back fixations is provided on channel steel and several vertically puts more energy into
The spacing of rib, vertical ribbed stiffener refers to seismic design provision in building code (GB50011-2010), sets at the upper lower flange of two channel steels
Several angle steel 6 corresponding two-by-two are set, two corresponding angle steel 6 are connected and fixed by the second bolt 7.
Referring to Fig. 6 to Fig. 9, opened in 1 web of steel skirt beam, 2 web of active beam link, skirt beam securing plate 3 and beam section securing plate 4
Equipped with the corresponding bolt hole in several positions, the depth of section of active beam link 2 is less than 1 section of steel skirt beam.
First bolt 5 uses high-strength bolt.
Double replaceable active beam links of channel cross-section-steel skirt beam connection structure installation method, comprising the following steps:
Step 1, in the fixed skirt beam securing plate 3 in 2 web two sides of steel skirt beam；
Step 2 welds two back-to-back fixed placements of channel steel several corresponding two-by-two at the upper lower flange of channel steel
Angle steel 6 corresponding angle steel 6 will be connected and fixed two-by-two by the second bolt 7, and complete combination active beam link 2；
Step 3 by the both ends of two 2 web of steel skirt beam insertion active beam links 2, and makes skirt beam securing plate 3 be placed in dissipative links
Between section 2 and 2 web of steel skirt beam；
Step 4 fixes active beam link securing plate 4 on active beam link 2；
