Cylindrical sleeve-type steel-wood composite joint and the assembly method

A cylindrical sleeve-type steel-wood composite joint, comprising fiberglass reinforced panel (FRP) cylindrical wood columns and X-shaped wood beams, and further comprising a key connecting component, arc connecting pieces and splicing outer ring plates, wherein the FRP cylindrical wood columns are connected through the key connecting component, the X-shaped wood beams are connected to the key connecting component through the arc connecting pieces, the splicing outer ring plates are arranged on upper and lower sides of the arc connecting pieces, and the splicing outer ring plates are fixed with bolts to realize combination and connection for assembling the cylindrical sleeve-type steel-wood composite joint;

• the key connecting component comprises cylindrical steel sleeve plates, a connecting sleeve, a cylindrical solid wood and filling wood blocks, wherein the cylindrical steel sleeve plates are arranged at upper and lower ends of the connecting sleeve, the cylindrical solid wood is arranged in the connecting sleeve, an inner diameter of the cylindrical steel sleeve plates is equal to an outer diameter of the FRP cylindrical wood columns, and the filling wood blocks encircle the connecting sleeve, are arranged between the upper and lower cylindrical steel sleeve plates and are fixed with glue;
• steel bar holes allowing penetrative steel bars to be inserted therein are formed in the cylindrical steel sleeve plates, corresponding steel bar holes are formed in the FRP cylindrical wood columns, and the penetrative steel bars penetrate through the corresponding steel bar holes in the cylindrical steel sleeve plates to integrally connect the FRP cylindrical wood columns in an axial direction;
• each arc connecting piece comprises a perforated arc base plate and two perforated arc steel plates, wherein the two perforated arc steel plates are arranged on the perforated arc base plate backing onto each other, and a space formed between the two perforated arc steel plates fits the X-shaped wood beams in shape;
• the arc connecting pieces are arranged around an outer circumference of the key connecting component, and each perforated arc base plate is fixed between two adjacent filling wood blocks with wood screws;
• and
• each splicing outer ring plate comprises a base plate and an arc hoop arranged on one side of the base plate, wherein bolt holes are formed in a surface of the base plate, and connecting clamps are arranged on the base plate;
• the adjacent splicing outer ring plates are connected through the connecting clamps;
• and after being connected, the adjacent splicing outer ring plates externally hoop a middle part of the key connecting component to clamp the filling wood blocks and are integrally connected to the arc connecting pieces and the X-shaped wood beams through bolts to transfer an internal force of the X-shaped wood beams.
