Inner ring ribbing large-span wood structure assembly type joint

Abstract

The invention belongs to the field of wood structure joint design, and relates to an inner ring ribbing large-span wood structure assembly type joint. Steel clamping plates are arranged on the left side and the right side of the end of each wood component, steel filling plates are inserted into plate slots at the ends of the wood components, the wood components, the steel clamping plates and the steel filling plates are connected through common bolts, and steel teeth are arranged on the faces where the steel clamping plates and the steel filling plates are in contact with the wood components;and under the effect of bolt pretightening force, the steel teeth are embedded into the wood components, the steel clamping plates and the steel filling plates are connected with a core steel cylinderthrough high-strength bolts, and steel plate ribs are arranged in the core steel cylinder. Bolt holes are formed in the corresponding positions of the wood components, the steel clamping plates, thesteel filling plates and the core steel cylinder in a factory, the parts are assembled through the bolts on a construction site, and the assembly degree of the large-span wood structure is improved; and the steel teeth on the steel clamping plates and the steel filling plates enhance mechanical occlusal force among the steel clamping plates, the steel filling plates and the wood components, slipping between the wood components and the steel plates is reduced, the initial rigidity of the joint is improved, so that the joint is close to a rigid joint, and the joint can be applied to a hectometer-grade large-span wood structure.

Description

technical field [0001] The invention belongs to the field of wood structure node design and relates to an assembled node of an inner ring ribbed large-span wood structure. Background technique [0002] The current large-scale reticulated shell buildings are mostly supported by steel structures, but the weight of steel is heavy and the construction is difficult. Timber structure is a structure in which the load is mainly borne by wood, and the components are connected and fixed by metal connectors or mortise and tenon joints. Wood has the advantages of easy material acquisition, light weight, easy transportation, and recyclability. Applying wood structures to large reticulated shell buildings can make full use of the superior compressive properties of wood. In 2013, the General Office of the State Council issued the "Green Building Action Plan", which provided policy support and guarantee for the development of wooden structure buildings. [0003] Bolt connection is a commo...

Patent 2017103672733 proposes a connection node of a wooden structure, which consists of a long and two disconnected wooden components. The components are connected by T-shaped steel plates and bolts. The connection is unreliable, and the connection between the wooden component and the steel plate is easy. Sliding occurs to reduce structural rigidity; patent 200920040633X proposes a composite material or composite wood long-span beam connection structure, the connector is inserted into the left and right two beam ends to form a long-span beam, the structure is composed of wood and wood, and the structure is complex. The construction efficiency is low and the ultimate bearing capacity is low, which limits the application in large spans of hundreds of meters
