Mullion connection structure for doors and windows

Abstract

Disclosed is a mullion connection structure for doors and windows. The structure mainly comprises a frame material, a mullion material and mullion connection pieces; the mullion connection pieces areof L-shaped structures and are fastened to the side edges of the frame material through bolts, the mullion material after being subjected to inverted processing is connected to the edges of the framematerial by inserting the mullion connection pieces into end face cavities of the mullion material, and the mullion material is fastened with the mullion connection pieces by transversely inserting the edges of the mullion material into the mullion connection pieces through bolts; gaps between the mullion material and the frame material are coated with glue for sealing treatment; the connection edge of one end of each L-shaped mullion connection piece abuts against the corresponding side edge of the frame material and is screwed into the corresponding side edge of the frame material from the end edge through bolts; the inner edge of a connection strip of each L-shaped mullion connection piece is provided with a lateral protruding block, the lateral protruding blocks are provided with screwholes, and the portions, corresponding to the screw holes, of the corresponding edges of the mullion material are provided with bolt holes communicated with the screw holes. The mullion connection structure has the advantages that the structure is easy to assemble and operate, the processing efficiency can be improved, and the pulling force is increased.

Description

Technical field [0001] The invention relates to a stile connection structure for doors and windows, and belongs to the technical field of building doors and windows. Background technique [0002] In the prior art, the universal connector of aluminum alloy doors and windows is used to connect the doors and windows and the middle stile, and the middle stile is provided with pin holes. The pins are driven into the middle stile through a pin gun to be fixedly connected with the connecting piece. The position, so that the connecting piece is squeezed by the pin and the frame at the same time, so that the middle stile and the frame are firmly connected. Such a pin is composed of a cylindrical body, which must accurately control the position of the pin hole on the stile; the above-mentioned stile connection structure has defects such as insufficient assembly process and complicated processing, which is not conducive to mass production. Summary of the invention [0003] The purpose of th...
