Fig. 6 is the oblique view of lower floor's grid interface point according to another embodiment of the present invention.
According to the space frame among Fig. 1 to 5, wherein having only an interface point is to be shown, and it is to comprise that two-layer tubulose vertically reaches horizontal chord up and down, intersects at interface point, and similarly the sloped tubular strut then is the interface point that is connecting two-layer grid.Interface point shown in the figure belongs to lower floor's grid, and here a vertical chord 10 is vertically to be crossed by a horizontal chord 11, and two tubulose chords are flattened at the interface point place, so that wealthyer a little.
Each chord is to be collapsed into like this, so that the end that is flattened and widens flat chord part 12 upper and lower surfaces is that to be a V shape or rectangular-shaped concavity 13, four bolts hole then be to pass flat chord part 12 and form.
The diameter of inclination strut 14 be than chord 10 and 11 for little, its each end separately is to be flattened or to change shape, so that being flattened end is to depart from from its axis, and it is in an acute angle by flexing along an x wire, connect liner 15 in order to form one, cut sth. askew from 45 degree angles or cut off for its terminal two jiaos, there is a bolt hole in terminal central authorities.Just because of strut connects that the biasing of liner 15 is shaped and its by the angle of flexing, thereby each strut 14 connect liners 15 near be to have a horizontal abut or a shoulder shape projection 16 to form.
Four groups of bolts 17 and nut 18 are to be applied to connecting securely two row chord 10 and 11 and four support bars 14 and four load distribution sheets together.All load distribution are foursquare, and Qi Sijiao is cut, and four bolts hole are then arranged therein, and the such load distribution sheet of each group is to comprise first 19; Second 20; The 3rd 21 and the 21a in revising model Fig. 5 as shown in Fig. 1 to 4; With the 4th 22.
