Description
Technical Field
[0001] The utility model relates to the technical field of ancient building reinforcement structures, and particularly relates to a floating column base stabilizing device for ancient building wooden columns. Background Technique
[0002] As a typical representative of ancient Chinese architecture, the most prominent structural feature of ancient wooden buildings is that the wooden columns are floating on the column bases. Under the action of repeated loads, the wooden columns and the column bases swing through friction, and the joint connection characteristics can be simplified to semi-rigid connections. Therefore, it is widely regarded as a system with excellent slip vibration isolation performance. However, as natural materials, the wooden structures of ancient buildings are easily affected by environmental factors such as temperature, humidity, and organisms for a long time, and the column bases are prone to cracking, decay, and insect damage, resulting in a decrease in the bearing capacity of the wooden column bases. Moreover, when the inclination degree is relatively large or affected by impact loads, it is easy for the column bases of the wooden columns to become unbalanced with the column bases, and the ability to resist lateral displacement is poor, which is extremely likely to cause joint damage, and then may lead to the imbalance and distortion of the entire structural system and be damaged.
[0003] In the reinforcement and repair of ancient buildings, the stability between the column bases and the column bases is often easily overlooked, and due to the inconvenient location for taking reinforcement measures, most of the current reinforcement methods are to groove and drill holes in the original wooden columns or column bases to add steel plates, steel bars, etc., causing secondary damage to the ancient buildings, which does not conform to the principles of ancient building repair and reinforcement, and the original historical value of the cultural relic components should be protected. Content of the Utility Model

[0030] The bottom ends of the four fixing members are all fixed on the bottom plate 401 and are evenly distributed along the circumferential direction of the bottom plate 401.
[0031] The annular sleeve 102 is sleeved on the wooden column 101 and is located above the column base stone 103, and the outer wall of the annular sleeve 102 is fixedly connected to the top ends of multiple fixing members.
[0032] One end of four adjustable damping limiters 2 is uniformly fixed on the inner wall of the annular sleeve 102, and the other ends are all in contact with the outer wall of the wooden column 101. The adjustable damping limiters 2 are used to prevent the excessive sliding of the wooden column 101.
[0033] As the specific structure of the fixing member, refer to Figure 5 , each fixing member includes an L-shaped steel plate 303, a stud and a connecting member 301.
[0034] The horizontal section of the L-shaped steel plate 303 is bolted to the top edge of the bottom plate 401. The top of the vertical section of the L-shaped steel plate 303 is threadedly connected to the screw rod 302, and the top of the screw rod 302 is threadedly connected to the bottom of the connecting member 301. The connecting member 301 is fixedly connected to the outer wall of the annular sleeve 102. The setting of the L-shaped steel plate 303 facilitates the fixing of the bottom plate 401. The setting of the screw rod 302 can not only increase the installation height of the annular sleeve 102, but also the thread on the screw rod 302 is convenient for connecting the L-shaped steel plate 303 and the connecting member 301.
[0035] In order to facilitate the connection between the annular sleeve 102 and the connecting member 301, four rib plates in the shape of triangular plates are welded on the outer wall of the annular sleeve 102. The four rib plates and the four connecting members 301 are in one-to-one correspondence. A U-shaped groove is provided at the connection between each connecting member 301 and the corresponding rib plate. Each rib plate is inserted into the opening of the corresponding U-shaped groove and bolted to the two side walls of the U-shaped groove. Specifically, a first bolt hole is penetrated through each rib plate, and second bolt holes are provided on both sides of the U-shaped groove. The rib plates in the shape of triangular plates not only improve the strength of the annular sleeve 102, but also facilitate the connection between the annular sleeve 102 and the connecting member 301.

[0041] The installation method of this solution is as follows:
[0042] S1. Measure the diameter of the wooden column 101 to be strengthened, raise the place where the wooden column 101 is located, properly move the column base stone 103 to the side, bury the bottom plate 401 directly below the position where the column base stone 103 is located, and the height should be lower than the floor elevation.
