Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1-5 shown.

[0025] A face-reinforced large-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 to form an L-shaped structure, 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 bottom plate on the other side of the glued wood column 2 by bolts so as to fix the metal connector on the glued wood column 2. The glued wood The end of the 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 in contact with the side wall of the U-shaped slot GFRP reinforcing ribs 5 of matching size are cemented on both sides of the GFRP (CFRP reinforcing plate...

Abstract

A face 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 a U-shaped inserting groove. The end portion of each glued wooden beam (3) is inserted in one U-shaped inserting groove and each U-shaped inserting groove is connected with one glued wooden beam (3) through connecting bolts. The face hole enhanced type large-span glued wooden post and beam connecting structure is characterized in that two side faces, in contact with one U-shaped inserting groove, of the end portion of each glued wooden beam (3) are respectively provided with a GFRP enhanced board (5) in a glued mode, wherein each GFRP enhanced board (5) is matched with one glued wooden beam (3) in size; each GFRP enhanced tube (6) is connected to a through hole in the end portion of one 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; four faces and bolt holes of a node zone are provided and connected with the GFRP enhanced boards (5) and the GFRP enhanced tubes (6) respectively in a glued mode, wherein the node zone is formed by connection of the glued wooden posts (2) and the glued wooden beams (3). The face 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 face-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...
