Abstract

The invention relates to a waterproof connecting angle of windows and doors in building. The waterproof connecting angle contains a right-angle connecting angle or a obtuse-angle connecting angle or an acute-angle connecting angle, wherein the connecting angle is of combination type and comprises a connecting piece with a right-angle or obtuse-angle or acute-angle plug and a double-pipe type connecting piece which fits with the plug in a sleeving manner; when the two connecting pieces are sleeved together, a sealing washer is sleeved on the junction surface of the end of the plug; and a fixing bolt is arranged between the two connecting pieces. The waterproof connecting angle of windows and doors in building of the invention adopts the sealing washer and fixes the sealing washer with the bolt, thus generating an outward expansion force and well and tightly contacting the connecting angle with the wall body of a door frame or a window frame for sealing; and the connection is firm and beautiful, the waterproof connecting angle has the advantages of simple structure, easy quick-assembly or quick-disassembly, obvious waterproof effect and convenient operation; and the connecting angle is easy to produce and process, thus extremely facilitating promotion and application.

Description

1. Technical field:

[0001] The invention relates to a connection angle of a door frame or a window frame in the construction field, in particular to a waterproof connection angle of a building door and window. 2. Background technology:

[0002] At present, door or window corner connectors in the field of construction rarely achieve the purpose of firm connection and better waterproofing at the same time. The simple connection method is to use 45° mating surfaces at 90° corners and apply glue on the mating surfaces to seal the connection. This connection method has low strength and may be damaged during construction or transportation. It is not suitable for long-term use requirements. The improved technology is to use the inner connection method for the corner connection of the door or window, which can make the appearance neat and beautiful, and will not interfere with the movement. However, this connection angle mainly plays the role of fixed connection, and the waterproo...
