Abstract

The invention relates to a rigid connection node of a wood frame structure. The rigid connection node comprises a beam member and a column member which are respectively a wooden beam and a wooden column; the rigid connection node further comprises a beam end steel sleeve and a column top steel sleeve, wherein the beam end steel sleeve is arranged on a part, positioned at a joint between the beam member and the column member, of the beam member in a sleeving manner; the column top steel sleeve is arranged on a part, positioned at a joint between the beam member and the column member, of the column member in a sleeving manner; the column top steel sleeve is fixedly connected with the beam end steel sleeve . Compared with technology of the prior art, the rigid connection node is advantageousin that steel sleeves are respectively arranged on a beam end and a column top, the rigid connection node is different from a normal wood structure pin connection node, friction type connection between high-strength screw bolts can be realized via the steel sleeves, pin grooves of wood material can be prevented from pressure bearing damage and splitting damage, the node is enabled to be sufficientin rotation stiffness and good in bending resistance, and requirements for rigid connection of beam and column nodes can be met.

Description

technical field [0001] The invention relates to a wood frame construction technology, in particular to a rigid connection node of a wood frame structure. Background technique [0002] Modern wooden structure is an important way to realize green low-carbon and construction industrialization. [0003] The main connection methods of modern wood structures are bolt connection, nail connection, etc., which are combined with metal connectors through fasteners such as pins and bolts. However, for ordinary pin-bolt joints, the decisive factor is the pin-slot compressive strength of the wood. Regardless of whether it is log or glued wood, the bearing strength of the pin groove is low; and the cross-sectional size of the wood member is limited, and the minimum distance between the bolts must meet the requirements. Therefore, the flexural bearing capacity and rotational stiffness of this connection joint are insufficient, and it is difficult to realize the effective transmission of b...
