Technical Field

The invention belongs to the technical field of accessories for assembling doors and windows, and particularly relates to a combined accessory applied to an outdoor cavity and an indoor cavity.

Background

When profile-assembled windows and doors are used, the connection between the profiles, such as the mullion-mullion connection or the frame-mullion connection, is usually included. The section bar for manufacturing the door and window generally comprises an indoor cavity and an outdoor cavity, and the middle parts of the section bar are connected into a whole through a heat insulation section bar. The stile-stile connection or the frame-stile connection is realized through the stile connecting piece.

The existing mullion connecting piece comprises an inner mullion connecting piece applied to an indoor cavity and an outer mullion connecting piece applied to an outdoor cavity.

The best stable state of the door and window is that the indoor cavity and the outdoor cavity are effectively connected, and the effective connection is that the bearing capacity of the connection part is good, the shearing resistance is good, the torsion resistance is good, and the tensile property is good.

The indoor chamber sets up usually and opens five metals and fixed glazing bead complex C type groove with door and window, and the contact jaw in corresponding interior muntin connecting piece and section bar C type groove sets up corresponding inboard recess and outside recess to be provided with from top to bottom the mounting hole, and realize fixedly interior muntin connecting piece and section bar through the jackscrew. Therefore, the inner mullion connecting piece realizes the forces in three directions of upward, leftward and rightward, and basically achieves relatively effective connection.

The outdoor cavity is relatively narrow compared with the indoor cavity due to cost and construction reasons, a C-shaped groove cannot be reserved, and when the door and window are connected in a support-support mode and a frame-support mode, an ideal mechanical state cannot be achieved in a good method. The mode (3) is the mainstream mode in the market at present.

The outer suspension wall of the outer cavity of the aluminum chamber can generally reserve an adhesive tape groove and a flat steel sheet groove, and only a single-side connecting piece is adopted to hang the grooves in a hook mode, so that the simple axial tensile effect is realized in the gap prevention mode during door and window assembly, and the axial tensile effect is realized only. For doors and windows, the tensile strength in one direction is not enough, and the method is a mechanical hinged support in an effective tensile force state, the torsion resistance is zero, and the shearing resistance of a small hook is not enough. And this kind of couple mode drops easily in the assembly process of door and window, causes rework, and is inconvenient.

In terms of mechanics, the connecting piece of the door and window should bear the force in the horizontal direction and the force in the vertical direction, and the torsion force caused by gravity, and the existing mullion connecting piece cannot achieve the effect.
