[0037] As Figures 1-7 shown, the present application provides a kind of antique building wood column foot node stable connection structure, including concrete foundation 10, connecting column 20, steel sleeve 30, wood column 40 and screw.

[0038] The top of the concrete foundation 10 is fixedly installed with a connecting steel plate 11 arranged in the transverse direction.

[0039] The connecting column 20 is arranged in the longitudinal direction and is fixedly connected with the connecting steel plate 11. The outer circumferential surface of the connecting column 20 is provided with at least one accommodating groove 21 extending inwardly in the transverse direction. The accommodating groove 21 is provided with a clamping block 22 and a spring 23. The clamping block 22 is arranged in the accommodating groove 21 and is in sliding contact with the inner wall of the accommodating groove 21. An inwardly extending threaded hole 24 is formed on the outer side surface of the clamping block 22. A downwardly inclined and outwardly extending guide surface 25 is formed on the top of the clamping block 22. The spring 23 is arranged in the transverse direction. The first end of the spring 23 is fixedly connected with the inner wall of the accommodating groove 21. The second end of the spring 23 is fixedly connected with the clamping block 22.

[0040] Steel sleeve 30 is longitudinally arranged and fixedly connected with connecting steel plate 11, steel sleeve 30 is located outside connecting column 20, and the axial line of steel sleeve 30 is collinear with the axial line of connecting column 20.

[0041] Wood column 40 is longitudinally arranged in steel sleeve 30, the bottom of wood column 40 is provided with connecting groove 41 matched with connecting column 20, and the inner wall of connecting groove 41 is provided with clamping groove 42 extending outward in the transverse direction, which is matched with clamping block 22.

[0042] The number of screws is at least one, the number of screws is the same as that of accommodating grooves 21, and the screws are arranged one by one. The screws are arranged on steel sleeve 30, the threaded ends of the screws are matched with threaded holes 24 on corresponding clamping blocks 22 after penetrating through steel sleeve 30, and the heads of the screws are in contact with the outer circumferential surface of steel sleeve 30. The outer circumferential surface of steel sleeve 30 is provided with recesses extending inward, which are used for hiding the heads of the screws.

[0043] Preferably, the number of screws and accommodating grooves 21 is four, and the screws are arranged one by one.

[0044] In the initial state, wood column 40 and the screws are separated from steel sleeve 30.

[0045] The specific construction process of the structure is as follows:

[0046] Firstly, the construction personnel inserts wood column 40 into steel sleeve 30 in the longitudinal direction through hoisting equipment, and wood column 40 moves downward under the action of gravity. In the process of moving downward, the bottom edge of connecting groove 41 is in contact with the guide surface 25 on clamping block 22, at this time, clamping block 22 moves inward, and spring 23 is in a compressed state. When the bottom of wood column 40 is in contact with connecting steel plate 11, clamping groove 42 is aligned with clamping block 22, at this time, clamping block 22 is partially pushed into clamping groove 42 under the action of the restoring force of spring 23, clamping block 22 limits the longitudinal movement of wood column 40, and steel sleeve 30 limits the horizontal movement of wood column 40, so as to stably connect wood column 40 and steel sleeve 30 together.

[0047] Then, the construction personnel threadedly matches the threaded ends of the screws with threaded holes 24 on corresponding clamping blocks 22 after penetrating through steel sleeve 30 in the transverse direction, and uses clamping blocks 22 to further enhance the connection stability between wood column 40 and steel sleeve 30, so that the overall structure can bear greater horizontal shear force and bending moment, and has better anti-seismic capacity.

[0048] The overall structure is not complex, the manufacturing process is simple, and when the construction is operated, the construction personnel only needs to insert wood column 40 into steel sleeve 30 in the longitudinal direction through hoisting equipment, and then tighten the screws, so that the operation and construction are very convenient.

[0049] In one embodiment, at least one positioning column 12 is further included, which is longitudinally arranged between the connecting column 20 and the steel sleeve 30 and fixedly connected with the connecting steel plate 11, and the length of the positioning column 12 is greater than that of the connecting column 20. The bottom of the wooden column 40 is provided with upwardly extending positioning holes 43 which are adapted to the positioning column 12. Preferably, the number of the positioning column 12 and the positioning hole 43 is both four, and they are arranged in sequence and at equal intervals along the circumference of the steel sleeve 30.

[0050] After the wooden column 40 is hoisted by the hoisting equipment, the positioning column 12 is first inserted into the positioning hole 43, at this time, the clamping block 22 and the clamping groove 42 are in the same vertical plane, so that when the subsequent clamping groove 42 is aligned with the clamping block 22, the clamping block 22 will partially enter the clamping groove 42 under the action of the spring 23.

[0051] Since the length of the positioning column 12 is greater than that of the connecting column 20, when the wooden column 40 is hoisted by the hoisting equipment and moves downward, the positioning column 12 will first cooperate with the positioning hole 43, so that the subsequent wooden column 40 can stably move downward, thereby improving the stability of the construction process. At the same time, the bottom of the wooden column 40 can be accurately inserted into the connecting groove 41, and the clamping block 22 can be accurately entered into the clamping groove 42, thereby playing a role of precise positioning and improving the construction efficiency.

[0052] In one embodiment, the number of the positioning column 12 is the same as that of the screw, and they are arranged one by one, and the positioning column 12 is provided with a through hole 13 through which the screw passes.

[0053] After the construction of the present application is completed, the threaded end of the screw passes through the through hole 13 on the steel sleeve 30 and the corresponding positioning column 12 and cooperates with the threaded hole 24 on the clamping block 22, at this time, the head of the screw is in contact with the outer wall of the steel sleeve 30, so that the connection points between the wooden column 40 and the steel sleeve 30 are more, and the connection stability between the wooden column 40 and the steel sleeve 30 is further enhanced, so that the overall structure can bear greater horizontal shear force and bending moment, and the anti-seismic capacity is better.

[0054] In one embodiment, the wooden column 40 includes a column body 44 and a column foot 45, the outer circumferential surface of the column body 44 is aligned with the outer circumferential surface of the steel sleeve 30, and the column foot 45 is adapted to the inner wall of the steel sleeve 30. The connecting groove 41, the positioning hole 43, the clamping groove 42 and the threaded hole 24 are all located on the column foot 45.

[0055] In this way, after the construction of the present application is completed, the outer circumferential surface of the column body 44 is aligned with the outer circumferential surface of the steel sleeve 30, so that the wooden column 40 and the steel sleeve 30 are more like a whole, thereby improving the overall aesthetic appearance of the present application.

[0056] In one embodiment, the bottom of the connecting steel plate 11 is fixedly installed with a plurality of anchor bars 14 embedded in the concrete foundation 10. Preferably, the number of anchor bars 14 is four, and the four anchor bars 14 are arranged equidistantly along the circumference of the connecting steel plate 11.

[0057] In one embodiment, the four anchor bars 14 are poured together with the concrete when the concrete foundation 10 is made, so as to improve the stability and connecting strength of the connecting steel plate 11.

[0058] In one embodiment, the number of positioning columns 12 is four, and the four positioning columns 12 are arranged equidistantly along the circumference of the steel sleeve 30.

[0059] According to a second aspect of the present application, a construction method is provided, comprising the following steps:

[0060] S1, a plurality of anchor bars 14 are embedded in the concrete foundation 10, and the connecting steel plate 11 is fixedly installed on the top of the concrete foundation 10 through the anchor bars 14.

[0061] S2, the construction personnel hoist the wooden column 40 through the hoisting equipment, control the wooden column 40 to move downward, insert the positioning column 12 into the positioning hole 43, and move the wooden column 40 downward. During the movement of the wooden column 40 downward, the bottom edge of the connecting groove 41 will be in contact with the guide surface 25 on the clamping block 22, at which time the clamping block 22 will move inward, and at this time the spring 23 is in a compressed state.

[0062] S3, when the bottom of the wooden column 40 is in contact with the connecting steel plate 11, the clamping groove 42 is just aligned with the clamping block 22, at which time the clamping block 22 will be partially pushed into the clamping groove 42 under the action of the restoring force of the spring 23, and the clamping block 22 limits the longitudinal movement of the wooden column 40, and the steel sleeve 30 limits the horizontal movement of the wooden column 40, thereby stably connecting the wooden column 40 and the steel sleeve 30 together.

[0063] S4, the construction personnel thread the threaded end of the screw through the steel sleeve 30 in the transverse direction and threadedly cooperate with the threaded hole 24 on the corresponding clamping block 22, which is used in cooperation with the clamping block 22 to further enhance the connection stability between the wooden column 40 and the steel sleeve 30, so that the overall structure can bear greater horizontal shear force and bending moment, and has better anti-seismic capacity.

[0064] In one embodiment, in step S5, the threaded end of the screw is cooperated with the threaded hole 24 on the clamping block 22 after passing through the through hole 13 on the steel sleeve 30 and the corresponding positioning column 12, at which time the head of the screw is in contact with the outer wall of the steel sleeve 30, so that the connection points between the wooden column 40 and the steel sleeve 30 are more, and the connection stability between the wooden column 40 and the steel sleeve 30 is further enhanced, so that the overall structure can bear greater horizontal shear force and bending moment, and has better anti-seismic capacity.
