The eight groups are divided into two parts, and the distance between two adjacent groups of connecting devices 6 in each part is the same. The through hole 61 is a T-shaped structure, and the threaded sleeve 62 is a hollow cylindrical structure. The inner wall of the threaded sleeve 62 is provided with a thread for matching the screw 64. The center of the outer wall of the threaded sleeve 62 is provided with a thread groove for threaded connection with the bolt 63. The length of the threaded sleeve 62 is less than or equal to the height of the building block 1. The bolt 63 is moved and inserted into the through hole 61 and threadedly connected to the center of the outer wall of the threaded sleeve 62. The length of the bolt 63 is less than the length of the horizontal part of the through hole 61, and the length of the screw 64 is less than or equal to the length of the through hole 61.
[0022] Insert the threaded sleeve 62 vertically into the through hole 61 of the block 1, align the thread groove on the threaded sleeve 62 with the horizontal part of the through hole 61, and then insert the bolt 63 longitudinally from the outside of the through hole 61. The bolt 63 is threadedly connected to the thread groove to complete the connection with the threaded sleeve 62, while limiting the movement of the threaded sleeve 62 in the through hole 61. Then rotate the screw rod 64, and the bottom end of the screw rod 64 is connected to the threaded sleeve 62. When the screw rod 64 is less than or equal to halfway into the threaded sleeve 62, take out another set of threaded sleeves 62, and the bottom end of the threaded sleeve 62 is screwed in. The upper threaded sleeve 62 is connected to the top of the screw rod 64, and the upper threaded sleeve 62 is squeezed and contacted with the lower threaded sleeve 62. The two groups of threaded sleeves are connected by the screw rod 64, and the other group of building blocks 1 is placed on the lower group of building blocks 1. The upper threaded sleeve 62 is moved and inserted into the through hole 61 of the upper group of building blocks 1. After performing the above steps, the threaded sleeve 62 is fixed in the through hole 61 by the bolt 64, thereby completing the vertical installation of building block 1. The same is true for building block 2, so that the connection between the two vertically adjacent groups of building blocks 1 is more stable to avoid displacement and detachment.
[0023] The positioning device 5 is arranged on both ends of the building block 1 and the building block 2. The positioning device 5 is used to horizontally connect the building block 1 and the building block 2. The positioning device 5 includes a slot 51 arranged at one end of the building block 1, and a block 52 for adapting to the slot 51 is arranged on the end of the building block 1 away from the slot 51. The slot 51 is a rectangular structure, and a positioning slot is arranged at the bottom of the slot 51. The block 52 is provided with a positioning hole. A rod for limiting the separation of the block 52 from the slot 51 is inserted into the positioning hole of the block 52.

The same is true for two sets of horizontally adjacent blocks 2. The vertical installation can complete the horizontal installation and clamping work at the same time, saving installation time and making the connection of two sets of horizontally adjacent blocks 2 more stable.
[0025] Working principle: The utility model vertically inserts the threaded sleeve into the through hole of the building block one, aligns the thread groove on the threaded sleeve with the horizontal part of the through hole, and then inserts the bolt longitudinally from the outside of the through hole. The bolt thread connects the thread groove to complete the connection with the threaded sleeve and limits the movement of the threaded sleeve in the through hole. Then the screw is rotated, and the bottom end of the screw is connected to the threaded sleeve. When the screw is less than or equal to half into the threaded sleeve, take out another set of threaded sleeves, the bottom thread of the threaded sleeve is connected to the top of the screw, and the upper set of threaded sleeves is squeezed and contacted with the lower set of threaded sleeves. The two sets of threaded sleeves are connected by the screw, and the other set of building block one is placed on the lower set of building block one. The upper set of threaded sleeves is moved and inserted into the through hole of the upper set of building block one. The above steps are performed. The threaded sleeve is fixed in the through hole by bolts to complete the vertical installation of block one, and the same is true for block two, so that the connection between the two vertically adjacent groups of block one is more stable and displacement and separation are avoided. One end of the slot of block two is aligned with one end of the block of block one, and block two is moved down, and the block is inserted into the slot (the threaded sleeve is inserted into the through hole at the same time) to complete the horizontal installation and clamping work, and then the insertion rod is inserted into the positioning hole and the positioning slot to limit the separation of the blocks and complete the horizontal installation of adjacent blocks one and two. The same is true for the two horizontally adjacent groups of block two. The vertical installation can complete the horizontal installation and clamping work at the same time, which saves installation time and makes the connection between the two horizontally adjacent groups of block two more stable.
