[0006] Preferably, there are two stiffening plates, which are respectively arranged on the front and back sides of the lifting member and fixedly connected to the lifting member, and the cross-section of the lifting member is rectangular.

[0007] Preferably, the top of the support plate is fixedly connected to an inner plug-in plate, and a wooden column is provided on the top of the support plate and plugged into an outer wall of the inner plug-in plate.

[0008] Preferably, the four corners of the base plate are provided with steel implantation holes, the top of the support plate is fixedly connected with four steel implantation columns, and the four steel implantation columns are respectively inserted into the four steel implantation holes, and the outer wall of the wooden column is fixedly inserted with two fixing rods.

[0009] Preferably, a gasket is sleeved on the outer wall of one of the chemical anchors, and the bottom of the gasket is welded to the bottom plate.

[0010] Preferably, a secondary pouring layer is provided between the base plate and the concrete foundation beam, and the inner wall of the concrete foundation beam is provided with eight embedded ribs, and the bottoms of the eight embedded ribs are contracted inward, and the outer walls of the eight embedded ribs are sheathed with steel wires.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The connection between the wood column and concrete achieves the purpose of half steel and half hinge. There is a section of square steel pipe between the bottom plate and the wood column to raise the bottom of the wood column so that the bottom of the wood column is above the finished surface of the building. On the one hand, it can meet the requirements of wood anti-corrosion and waterproofing, and on the other hand, it can leave a certain amount of installation space. (If the internal force is relatively small, the square steel pipe will be made into a cross steel pipe, so that the bottom plate can be made smaller) Screws are welded on the end plate under the wood column, holes are opened on the wood column, and structural glue is poured to serve as a bending and shear connection for the column foot. An inner insert is welded on the end plate under the wood column, and the inner insert and the wood column are connected with through bolts / pins as a supplement to the shear connection of the column foot.
