DETAILED DESCRIPTION

[0018] To further illustrate the concept of the present invention, the following will further illustrate the specific implementation of the present invention in conjunction with the accompanying drawings:

[0019] A back bolt type dry hanging stone connection structure, taking a long strip of steel plate 2 and two steel bars 3, the two steel bars 3 are vertically welded on the steel plate 2, and the two steel bars 3 are parallel to each other to form a steel profile 1, such as Figure 1 shown.

[0020] Take three plates, weld two of them vertically to another plate, and form the horizontal plate 7 and vertical plate 6 of the first connector 4. The width of the horizontal plate 7 should be greater than the width of the steel bar 3, and the spacing of the horizontal plate 7 should be consistent with the spacing of the steel bar 3 during welding. Then take two plates as the card plates 12, cut the card plates 12, and process one side of the card plates 12 into an inclined surface, so that the cross section of the card plates 12 forms an isosceles trapezoid, and then weld the processed card plates 12 to the horizontal plate 7, with the welding position close to the vertical plate 6. When welding, let the unprocessed surfaces of the two card plates 12 face each other, with the inclined surface facing outward, and then cut a locking groove 13 at the bottom of the inclined surface to form a protruding structure 8, and make the first connector 4, such as Figure 2 shown.

[0021] Take a plate as the connecting plate 9, weld a steel groove as the connecting groove 10 at the upper end of the connecting plate 9, weld a triangular reinforcing rib 16 at the connection between the connecting groove 10 and the connecting plate 9, the opening of the connecting groove 10 is downward, and the inside of the connecting groove 10 is processed to make the connecting groove 10 match the shape of the protruding structure 8 of the first connector 4, and the mouth of the connecting groove 10 has a latching tooth 14 that engages with the locking groove 13, and finally install the back bolt 11 on the connecting plate 9 to make the second connector 5, such as Figure 3 shown.

[0022] Take a bolt as the connecting bolt 15, connect the first connector 4 and the second connector 5 through the connecting groove 10 and the protruding structure 8, and then drill vertically downward from the top of the connecting groove 10 to drill a through hole on the cross plate 7 and the connecting groove 10 so that the connecting bolt 15 can pass through the through hole.

[0023] When installing the stone, first fix multiple steel sections 1 horizontally on the main body of the building according to the predetermined drawings. The fixing method can be fixed with expansion bolts to make the steel bars 3 parallel to the horizontal plane. Then connect the first connector 4 to the steel section 1, let the first connector 4 protrude the structure 8 upward, and the two cross plates 7 are respectively located above the two steel bars 3. Then, drill holes downward from the top of the cross plates 7, use bolts to completely fix the cross plates 7 and the steel bars 3, and install multiple first connectors 4 on the steel section 1 according to the calculated distance. Then, according to the calculated position, the second connector 5 is installed on the back of the stone. The second connector 5 is fixed to the back of the stone by the back bolt 11 to ensure that the connection groove 10 opens downward. After multiple second connectors 5 are installed on the back of the stone, the stone is lifted to a predetermined installation position. The stone height is first raised to a height higher than the predetermined position, and the position is adjusted so that the second connector 5 is located above the first connector 4. After the connection groove 10 is aligned with the protruding structure 8, the stone height is lowered, and the protruding structure 8 is inserted into the connection groove 10. When the latch teeth 14 and the locking groove 13 are engaged, the position of the stone is fixed. Then, the second connector 5 and the first connector 4 located at the top on the back of the stone are fixed with the connecting bolts 15. After the connecting bolts 15 pass through the through holes on the connecting groove 10 and the cross plate 7, the nuts are tightened. Figure 4 , Figure 5 As shown, the stone installation work is completed.

[0024] When installing stones, in order to improve construction efficiency, only the top first connector 4 and second connector 5 can be fixed with connecting bolts 15. The first connector 4 and second connector 5 at other positions have been engaged through the protruding structure 8 and the connecting groove 10, which can meet the needs of stone fixing. A triangular reinforcing rib 16 is set on the second connector 5, and the structural strength of the second connector 5 is greatly improved to bear the weight of the stone. During installation, the number of second connectors 5 used for a single piece of stone can be set according to the size of the stone, and can be adjusted according to actual conditions.
