Embodiment 1

[0028] Such as Figure 1-3 shown.

[0029] A slot-reinforced long-span glulam post-beam connection structure, which includes a metal connector 1, the metal connector 1 is composed of a bottom plate and an insert to form a T-shaped structure, such as figure 1 , 2 shown. The bottom plate is in contact with one side of the glued wood column and is connected with another bottom plate on the other side of the glued wood column through bolts, and then the metal connector 1 is fixed on the glued wood column 2 . The insert block is inserted into the slot 4 at the end of the glued wood beam 3, the insert block and the glued wood beam 3 are connected by connecting bolts, and the two faces of the slot 4 opposite to the insert block Cemented with GFRP reinforced plate 5, such as image 3 shown. The four surfaces of the node area where the metal connector is installed on the glued wood column are respectively glued with GFRP reinforcing plates (5). The thickness of GFRP reinforced pl...

Embodiment 2

[0032] Such as figure 1 , 2 , 4 shown.

[0033] A slot-reinforced long-span glulam post-beam connection structure, which includes a metal connector 1, the metal connector 1 is composed of a bottom plate and an insert to form a T-shaped structure, such as figure 1 , 2 As shown, the bottom plate is in contact with one side of the glued wood column 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, and the plug Inserted into the slot 4 at the end of the glued wood beam 3, the plug and the glued wood beam 3 are connected by connecting bolts, and the two faces of the slot 4 opposite to the plug are glued with GFRP reinforcement boards 5 (in practice, a CFRP reinforced plate can also be used instead of a GFRP half-plus plate). The two or four relative surfaces of the node area where the metal connector is installed on the glulam column are respectively glued with GFRP...

Abstract

A rabbet-enhanced large-span glued wooden column beam connecting structure comprises a metal connecting part (1), wherein the metal connecting part (1) is composed of an inserting block and a bottom plate, the bottom plate is contacted with one surface of a glued wooden column, the metal connecting part (1) is fixed on the glued wooden column (2) after the bottom plate is connected with the other bottom plate arranged on the other side surface of the glued wooden column through a bolt, the inserting block is inserted into a rabbet (4) formed in the end portion of a glued wooden beam (3), and the inserting block and the glued wooden beam (3) are connected through a connecting bolt. The rabbet-enhanced large-span glued wooden column beam connecting structure is characterized in that GFRP reinforcement plates (5) are cemented on two surfaces, opposite to the inserting block, of the rabbets (4), GFRP reinforcement plates are cemented on four surfaces of a node region arranged on the glued wooden column, and the node region is connected with the glued wooden beam. The rabbet enhanced large-span glued wooden column beam connecting structure can improve the capacity of load bearing, reduces concentrated distribution of stress, changes a damage mode of a connecting node, and is beneficial to reduction of the size of the connecting structure and cost of construction.

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 slot reinforced large-span glued wood columns and beams connection structure. 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 size and enhance th...
