Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, this embodiment provides a semi-rigid column base connecting device for a wooden column, which includes a wooden column 1, a hardware connecting member 2 and an embedded part 3, a cylindrical tongue-and-groove 11 has been opened upwards at the bottom middle position of the wooden column 1, and a plurality of bar planting holes 12 have been opened upwards uniformly around the cylindrical tongue-and-groove 11 at the bottom of the wooden column 1. Hardware connection spare 2 includes circular steel tube 21, the lower part and the bottom of circular steel tube 21 are fixed with first annular end plate 22 and second annular end plate 23 respectively, the pinhole 24 with plant muscle hole 12 one-to-one is seted up along the circumferencial direction on the first annular end plate 21.

Each plant and to have full thread to plant muscle pole 4, and full thread to plant muscle pole 4 and correspond and plant muscle hole 12 inner walls and closely bond through special bar planting glue (if adopt epoxy or polyurethane adhesive) in the muscle hole 12, each the bottom end of full thread bar 4 is planted and is passed corresponding pinhole 24 and through the nut fastening, round steel pipe 21 imbeds in the cylindrical tongue-and-groove 11, second annular end plate 23 welds with built-in fitting 3 mutually.

Between first annular end plate 22 and the second annular end plate 23 and avoid pinhole 24 position to consolidate along the circumferencial direction and have a plurality of stiffening plate 25, these some stiffening plates 25 constitute the rice style of calligraphy, first annular end plate 22, second annular end plate 23 and stiffening plate 25 welding form one end built on stilts layer for be higher than ground with the 1 chassis of post, play dampproofing and waterproofing effect.

In this embodiment, the wood column 1 is made of laminated wood, sawn timber, laminated veneer lumber, parallel wood chip laminated wood, laminated wood chip laminated wood, or a sandwich composite material with wood as a core material.
