Windproof and waterproof glue injection corner connector and connecting structure thereof

Abstract

The invention provides a windproof and waterproof glue injection corner connector, which comprises a first fixing arm and a second fixing arm. The first fixing arm and the second fixing arm are in right-angle connection to form an L shape. An R-shaped limiting point is arranged on the first fixing arm; a positioning reference point is arranged on the second fixing arm; C-shaped grooves are formedin the ends of the first fixing arm and the second fixing arm; and threads are arranged in the C-shaped grooves. The invention also provides a connecting structure of the windproof and waterproof glueinjection corner connector. The windproof and waterproof glue injection corner connector and the connecting structure thereof are high in universality, and are suitable for assembling doors and window frame sashes of aluminum alloy section bars, heat insulation thermal break aluminum alloy section bars, aluminum-wood composite section bars, stainless steel section bars, and aluminum-plastic aluminum section bars and plastic steel section bars, accurate and rapid assembling of the door and window section bars through the glue injection corner connector can be achieved, the assembling quality is guaranteed, the labor cost is saved, the corner joint connecting strength can be improved, the water tightness, the air tightness, the heat preservation performance and the sound insulation performance of a door and window are improved, and the door and window K value (U value) coefficient is reduced.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a windproof and waterproof glue-injected corner bracket and a connection structure for windproof and waterproof glue-injected corner brackets. Background technique [0002] With the development of technology, the doors and windows used in engineering buildings and civil buildings have gradually developed from the original wooden window materials to plastic steel door and window profiles, aluminum alloy door and window profiles, aluminum alloy broken bridge insulation door and window profiles, and aluminum-wood composite door and window profiles. , aluminum-plastic co-extruded door and window profiles, aluminum-plastic-aluminum composite profiles, polyurethane door and window profiles, and stainless steel door and window profiles are the mainstream door and window products. Door and window profiles need to be connected and fixed at four corners during the assembly proces...

AI Technical Summary

Problems solved by technology

[0004] The first type is the L-type 90° right-angle bracket, which is a traditional right-angle bracket with a simple structure. However, when the L-type 90° right-angle bracket is connected to the door and window profiles, it needs to be stamped and fixed by special assembly angle mechanical equipment. Misalignment and loosening of sharp corner joints are prone to occur, and height differences are prone to occur on the plane, which makes it difficult to clean the end-face glue, easy to remain, and easy to pollute the surface of the profile; and the corner code cannot be operated by one person alone when assembling corners, and multiple people are required to cooperate and assemble , which increases the labor cost; and the frame, stile, and crimping line cannot be assembled at one time, which increases the time cost; and the area of ​​single stile doors and windows is too large, which is inconvenient for vehicle transportation and difficult for high-rise building transportation, which increases the transportation cost

[0005] The second type is movable corner brackets, which are fixed by screws after positioning with spring pins. However, after the movable corner brackets are connected to door and window profiles, the assembly gap between the movable corner brackets and the profile cavity is relatively large; and it is easy to fix the holes when tightening with screws The corners cannot be locked due to deviations; and it is easy to cause sharp corner misalignment of the corner contacts, the height difference is easy to appear on the flat front, it is inconvenient for the corner code to enter and exit the profile cavity during assembly, and the spring pin is easy to fall off; and the corner contacts cannot be injected with waterproof glue , leading to poor watertightness and airtightness of the corner code connection structure, resulting in low stability of the corner joints of the assembled finished product, and easy to loosen and misplace during transportation; and the corner code of the split combination is less efficient when assembling screws , increased labor costs

[0006] The third type is screw-fixed corner brackets, which use screws to connect the corner brackets and door and window profiles, but the fixing of screw-fixed corner brackets requires a drilling process, a tapping screw hole processing process, and a drilling and injection waterproof sealant inflow hole process. The investment cost of mechanical equipment is high, the process is complicated and the efficiency is low; and once the drilling position or profile punching position deviates, it will easily lead to a difference in height of the group angle plane, which requires high processing and increases labor costs.
