Description
Technical Field
The invention relates to the technical field of civil engineering, in particular to a self-resetting swinging glued wood column with a column shoe.
Background
At present, most of the timber column base adopts a node form of bolt connection. The common forms are steel filling plates and steel clamping plates, wood members are connected by bolts, and the node form mainly utilizes the bending resistance of the bolts and the local bearing of wood at the bolts to provide bearing capacity. The node form has several problems:
1. due to construction deviation, a gap exists between the wall of the bolt hole on the wood column and the bolt, and the gap causes the wood beam to slide after being stressed, so that the initial rigidity of the node is lower.
2. Due to the low tensile strength of the wood cross grains, when the screw hole pin grooves bear pressure, brittle failures such as column base cross grain splitting and the like often occur, and the bearing capacity of the wood column is reduced.
3. The bearing capacity is provided through the modes of bolt yielding, pressed yielding of wood at bolt holes and the like, and after an earthquake, large residual deformation exists, so that the earthquake resistance is reduced.
Therefore, in order to solve the above problems, a wood-structure column base connection node form with high initial rotational rigidity, high bearing capacity and small residual deformation is urgently needed.

1. after the column shoe is added into the column base of the glued wood column, the stress area of the column base is increased, and the stress of the column base of the glued wood column can be effectively reduced to protect the column base node; in addition, under horizontal force, the enlarged column base can resist side load by providing restoring force, thereby enhancing the earthquake-resistant performance of the laminated wood column.
2. After the bolts are prestressed, the belleville springs have certain compression deformation, and meanwhile, the column shoe bottom plate 9 and the foundation contact surface have interaction force to form restraint moment, so that the initial rotational rigidity of the cemented wood column base joint is improved.
3. The steel base plates are arranged between the left side and the right side of the laminated wood column and gaps between the left side and the right side of the laminated wood column and the column shoes, and the laminated wood column which is locally contacted with the column shoes is effectively protected under the horizontal displacement of the column.
4. The glued wood column is placed in the column shoe and connected through the self-tapping screw, so that the integrity of the glued wood column and the column shoe is improved.
5. The column shoes are floatingly arranged on the top surface of the foundation and connected through high-strength bolts, when the wooden columns are acted by horizontal force,
due to the long circular holes reserved in the column shoe bottom plate 9, the glued wood column can be lifted together with the column shoe to swing, and self-resetting is achieved through the restraining moment of the disc spring.
