Embodiment 1

[0026] Such as Figure 1-3 shown.

[0027] A contact surface enhanced long-span glued wood column-beam connection structure, which includes a metal connector 1, the metal connector 1 is composed of a bottom plate and a U-shaped slot, such as Figure 4 , 5 As shown, the bottom plate is in contact with one side of the glued wood column 2 and is connected to the other bottom plate on the other side of the glued wood column by bolts, and then the metal connector 1 is fixed on the glued wood column 2. The end of the wooden beam 3 is inserted into the U-shaped slot, and the U-shaped slot and the glued wood beam 3 are connected by connecting bolts, and the end of the glued wood beam 3 is connected to the side wall of the U-shaped slot. GFRP reinforcing plates 5 of matching size are cemented on both sides of the contact (CFRP reinforcing plates can also be used instead of GFRP plates during specific implementation), such as image 3 shown. The four surfaces of the node area where ...

Abstract

The invention discloses a contact surface reinforcing type long-span gluing wooden pillar beam connecting structure which comprises metal connecting pieces (1). The metal connecting pieces (1) are composed of base plates and U-shaped inserting grooves. One base plate is contacted with one surface of a gluing wooden pillar and is connected with the other base plate on the other side face of the gluing wooden pillar through bolts, and then the metal connecting pieces (1) are fixed on the gluing wooden pillar (2). The ends of a gluing wooden beam (3) are inserted into the U-shaped inserting grooves, and the U-shaped inserting grooves and the gluing wooden beam (3) are connected through connecting bolts. The contact surface reinforcing type long-span gluing wooden pillar beam connecting structure is characterized in that GFRP reinforcement plates (5) which are matched in size are arranged on two contacting side faces of the gluing wooden beam (3) and the side walls of the U-shaped inserting grooves in a bonding mode, and four surfaces, in node areas where the metal connecting pieces are installed, of the gluing wooden pillar are provided with GFRP reinforcement plates (5) respectively in a bonding mode. By means of the contact surface reinforcing type long-span gluing wooden pillar beam connecting structure, bearing capacity can be improved, the concentrated distribution of stress is lightened, the failure mode of connecting nodes is changed, the size of the connecting structure can be better decreased, and construction cost is lowered.

Description

technical field [0001] The invention relates to a building structure, in particular to a connection structure of glued wood columns and beams, in particular to a connection structure of large-span glued wood columns and beams with enhanced contact surface. Background technique [0002] At present, domestic studies on glulam bolted joints, fiber-reinforced beams (columns), and fiber-reinforced log mortise and tenon joints have been done, but there is no report on the experimental research on fiber-reinforced glulam bolted joints. There is no report on the domestic theoretical research on fiber-reinforced glulam bolted joints. At home and abroad, there are no reports on the application of fiber-reinforced glulam bolted joints to large-span and large-scale modern wood structure systems to reduce the size, weight and optimal design of structural components. Therefore, it is very important to design a beam-column connection structure that can effectively reduce the connection si...
