The second screw 10 is also passed through the first connection member 7.

[0040] like Figure 4 As shown, the first connecting member 7 includes a first bottom plate 701, a first accommodating cavity 702 and a first anti-shear cone 703 are fixed above the first bottom plate 701, the first accommodating cavity 702 is located in the first zone a of the first bottom plate 701, the first anti-shear cone 703 is located in the second zone b of the first bottom plate 701, a first top plate 704 is fixed on the top of the first accommodating cavity 702, a second anti-shear cone 705 is fixed above the first top plate 704, a first through hole 706 penetrating the first bottom plate 701 is opened on the first anti-shear cone 703, a second through hole 707 penetrating the first top plate 704 is opened on the second anti-shear cone 705, and a third through hole 708 is opened on the first zone a of the first bottom plate 701.

[0042] like Figure 1-3 As shown, the first connecting member 7 and the second connecting member 8 are arranged in pairs. When the two are matched, the first bottom plate 701 is located below the second top plate 801, the first accommodating cavity 702 is located in the fourth zone d of the second top plate 801 and the second anti-shear cone 705 is passed through the fourth through hole 804, and the second accommodating cavity 802 is located in the second zone b of the first bottom plate 701 and the first anti-shear cone 703 is passed through the fifth through hole 805.

This can prevent the first single nut 709 and the second single nut 710 from loosening after being screwed into the first screw rod 9 by external force, thereby affecting the stability of the system.

[0045] like Figure 1-3As shown, the first screw rod 9 and the second screw rod 10 connected and the second screw rod 10 and the second screw rod 10 connected are connected by a connecting sleeve 16. The inner wall of the connecting sleeve 16 includes a threaded area 1601 and a non-threaded area 1602, and the non-threaded area 1602 is located in the middle of the threaded area 1601 to divide the threaded area 1601 into two upper and lower parts for limiting the first screw rod 9 or the second screw rod 10 in the connecting sleeve 16. Preferably, the non-threaded area 1602 is located in the middle of the threaded area 1601 to divide the threaded area 1601 into two upper and lower symmetrical parts. The lower end of the connecting sleeve 16 is against the first shear cone 703 or the second shear cone 705 coaxial below to resist the shear force on the module system.

[0046] Preferably, if Figure 1-3 , Figure 6 As shown, a screw guide groove 1603 inclined toward the inner hole is provided at the upper end of the connecting sleeve 16 so that the first screw 9 or the second screw 10 cooperating with the threaded area 1601 in the upper inner part of the connecting sleeve 16 can enter the connecting sleeve 16 more smoothly.

[0047] like Figure 1-3 As shown, anti-loosening washers 17 are arranged between the connecting sleeve 16 and the first anti-shear cone 703 or the second anti-shear cone 705 , between the first double nut 13 and the cushion block 14 in the top connecting node 2 , and between the second double nut 15 and the second top plate 801 .

The length of the second screw 10 is larger than the vertical height of the first accommodating cavity 702 and the second accommodating cavity 802, and the second screw 10 needs to be connected with other second screws 10 or first screws 9 in sequence to penetrate all module layers in the vertical direction to resist the tension exerted on the module system.

[0049] During installation, install the bottom module layer first. Fix the two-dimensional bottom plate 6 first, and then fix the module 1 of the bottom module layer to the two-dimensional bottom plate 6 through the basic connection node 5.

The screwing length is the length of the threaded area 1601 of the connecting sleeve 16 located at the top.

[0050] Then, the middle module layer is installed, and the two adjacent module layers are connected by a number of standard inter-layer connection nodes 4. The standard inter-layer connection nodes 4 are spliced ​​by screwing the connection sleeves 16 on the upper ends of the two second screws 10, and then the other two second screws 10 are inserted from the module column top into the screw guide groove 1603 of the connection sleeve 16 for positioning, and then screwed to connect with the connection sleeve 16. The screwing length is the length of the threaded area 1601 of the connection sleeve 16 located at the top.

[0051] Finally, install the top module layer. First install the module 1 of the top module layer, and then fix the two-dimensional top plate 3 to the module 1 of the top module layer through the top connection node 2. The splicing of the top connection node 2 is to set the cushion block 14 on the upper end of the second screw 10 inserted in the first accommodating cavity 702, and then screw the first double nut 13 to fix the second screw 10 to the second connecting member 8. Screw the upper end of the second screw 10 inserted in the second accommodating cavity 802 onto the connecting sleeve 16, and then insert the first screw 9 from the sixth through hole 806 of the second connecting member 8 including the second top plate 801 into the screw guide groove 1603 of the connecting sleeve 16 for positioning, and screw it to connect with the connecting sleeve 16. The screwing length is the length of the threaded area 1601 located above the connecting sleeve 16.
