Not Gu Dingdao four corner locations on the inside of shear wall frame, the design of above structure improves the skew force of skewed horizontal load part 5
To the transmission capacity of transverse joint, the stress concentration phenomenon that the end of skewed horizontal load part is also easy to produce can be alleviated.
As in Figure 2-4, bindiny mechanism 300 further includes the first bolt 303 and the second bolt 304；The of first bolt 303
One end sequentially passes through the first connecting plate 301, the first facade steel plate 6 of the first shear-wall element 100, the first shear-wall element 100
Upper concealed beam, the first shear-wall element 100 the second facade steel plate 7 and the second connecting plate 302 and with the first nut cooperate with will
Bindiny mechanism 300 is connected and fixed with the first shear-wall element 100；The first end of second bolt 304 sequentially passes through the first connecting plate
301, the first facade steel plate 6 of the second shear-wall element 200, the lower concealed beam of the second shear-wall element 200, the second shear-wall element
200 the second facade steel plate 7 and the second connecting plate 302 simultaneously cooperate with the second nut with by bindiny mechanism 300 and the second shear wall
Unit 200 is connected and fixed.First connecting plate 301 and the second connecting plate 302 are located at the first shear-wall element 100 and second and cut
The front and rear sides of 200 intersection location of power wall unit.By the cooperation of the first bolt 303 and the first nut by the first connecting plate 301
Lower end and the second connecting plate 302 lower end be fixed to the first shear-wall element 100 upper concealed beam on.Pass through the second bolt 304
The upper end of first connecting plate 301 and the upper end of the second connecting plate 302 are fixed to the second shear wall list by the cooperation with the second nut
In the lower concealed beam of member 100.Wherein the first bolt 303 and the second bolt 304 are split bolt, and the both ends of split bolt are spiral shell
Mother, nut offset with corresponding first connecting plate 301 or the second connecting plate 302.
As shown in figure 4, the first connecting plate 301 and the structure having the same of the second connecting plate 302 are I-shaped template；Its
In, the first connecting plate 301 includes the first wing plate 3011, the second wing plate 3012 and the first wing plate 301 of connection and the second wing plate 302
Wing plate connecting plate 3013；
The position of first wing plate 3011 and the left sleeper of the first shear-wall element 100 and a left side for the second shear-wall element 200
The position of the junction of sleeper is opposite.The width of first wing plate 3011 is greater than the width of wing plate connecting plate 3013, to make
The both ends of one wing plate 3011 can be respectively fixed to the left sleeper and second shear-wall element 200 of the first shear-wall element 100
On left sleeper, to improve the bonding strength of the first connecting plate 301.
The position of second wing plate 3012 and the right sleeper of the second shear-wall element 200 and the right side of the first shear-wall element 100
The position of the junction of sleeper is opposite.The width of same second wing plate 3012 is greater than the width of wing plate connecting plate 3013, from
And the both ends of the first wing plate 3011 is enable to be respectively fixed to the right sleeper and the second shear-wall element of the first shear-wall element 100
On 200 right sleeper, to improve the bonding strength of the first connecting plate 301.
Under the upper concealed beam and the second shear-wall element 200 of 3013 position of wing plate connecting plate and the first shear-wall element 100
The position of the junction of concealed beam is opposite.Likewise, the structure of the second connecting plate 302 is identical as the structure of the first connecting plate 301, only
It is the front and rear sides that the first connecting plate 301 and the second connecting plate 302 are located at shear wall.
