Embodiment 1

[0027] like Figure 1-3 shown.

[0028] A screw hole reinforced 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 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 1 and is connected to the bottom plate on the other side of the glued wood column 2 by bolts so as to fix the metal connector 1 on the glued wood column 2, and the plug The block is inserted into the slot 4 at the end of the glulam beam 3, and the plug-in block and the glulam beam 3 are connected by connecting bolts, and GFRP is also glued in the through hole at the end of the glulam beam 3 for passing the connecting bolt Enhanced tube 6, such as image 3 As shown, in specific implementation, GFRP reinforced pipes 6 should also be glued in the bolt holes in the joint area where the metal connector 1 is installed on the glued woo...

Embodiment 2

[0031] like figure 1 , 2 , 4 shown.

[0032] A screw hole reinforced 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 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 1 and is connected with the bottom plate on the other side of the glued wood column 2 by bolts so as to fix the metal connector 1 on the glued wood column 2, and the plug is inserted into the glued In the slot 4 at the end of the wooden beam 3, the insert block and the glued wood beam 3 are connected by connecting bolts, and a GFRP reinforced pipe 6 ( During specific implementation, CFRP reinforced tubes can also be used instead of GFRP reinforced tubes), and GFRP reinforced plates 5 are bonded on two opposite sides of the socket 4 at the same time (CFRP reinforced plates can also be used instead during specific implementat...

Abstract

A screw hole enhanced type large-span glued wooden post and beam connecting structure comprises metal connecting pieces (1). Each metal connecting piece (1) is composed of base boards and an inserting block. One base board is in contact with one face of a glued wooden post (2) and connected with the other base board at the other side of the glued wooden post (2) through bolts, so that each metal connecting piece (1) is fixed on the glued wooden post (2). Each inserting block is inserted in one inserting groove in the end portion of one glued wooden beam (3) and each inserting block is connected with one glued wooden beam (3) through connecting bolts. The screw hole enhanced type large-span glued wooden post and beam connecting structure is characterized in that a GFRP enhanced tube (6) is connected to a through hole in the end portion of each glued wooden beam (3) in a glued mode, wherein the through hole is used for being connected with a connecting bolt in a penetrating mode; each GFRP enhance tube (6) is connected to a bolt hole of a node zone, connected with one glued wooden beam, on one glued wooden post (2) in a glued mode. The screw hole enhanced type large-span glued wooden post and beam connecting structure is capable of improving bearing capacity, reducing concentrated distribution of stress, changing a failure mode of a connected node, facilitating reduction of the size of the connecting structure, and reducing the manufacturing cost of engineering.

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 reinforced long-span glued wood column 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 the beari...
