Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 2 BRB cross-brace constructions of the present utility model, including entablature 1, sill 2, the and of the first column 3
Second column 4, the entablature 1 and sill 2 be all connected between the first column 3 and the second column 4 and with the first column 3 with
And second column 4 form frame-type structure, the frame-type structure it is diagonal on be provided with BRB cross supports, the BRB cross supports
Including the first BRB supporting sections 6, the 2nd BRB supporting sections 7, the 3rd BRB supporting sections 12 and the 4th BRB supporting sections 13, the entablature
Cross member 5 is provided between 1 and sill 2, the BRB strong points 8, the first BRB supports are provided with the cross member 5
6 upper ends of section are connected to the intersection of the first column 3 and entablature 1, and lower end is connected on the BRB strong points 8, the 2nd BRB branch
Support section 7 upper end is connected on the BRB strong points 8, and lower end is connected to the second column 4 and the intersection of sill 2, the first BRB
The BRB supporting sections 7 of supporting section 6 and the 2nd are located on same axis, and the upper end of the 3rd BRB supporting sections 12 is connected to the second column 4
With the intersection of entablature 1, lower end is connected on the BRB strong points 8, and the upper end of the 4th BRB supporting sections 13 is connected to BRB supports
On point 8, lower end is connected to the intersection of the first column 3 and sill 2, the 3rd BRB supporting sections 12 and the 4th BRB supporting sections
13 on same axis.
Sleeve pipe is provided with because BRB supports are outside, global sections are larger, and therefore, it is difficult to arranged crosswise.And if only it is to hand over
