Embodiment Construction

[0011] Such as figure 1 , figure 2 and image 3 As shown, the connection method of the plastic-steel door and window corner coupler part of the present invention is: firstly, a reinforcing member 3 matching the inner cavity of the plastic profile is made; After steel liner 1 is inserted into the cavity of plastic profile 2, the distance from one end to the coupling end of plastic profile 2 is greater than the length of the right-angled side of reinforcement 3 by 1-5 mm, so as to overcome steel liner 1, reinforcement 3 and plastic profile 2 Deformation effects due to different shrinkage and expansion rates. Then, insert the pre-prepared L-shaped reinforcement 3 into the cavities of two adjacent plastic profiles 2. Fill with adhesive, push two adjacent plastic profiles to couple. The adhesive will gradually solidify with the passage of time, so that the reinforcement 3 and the plastic profile 2 are closely combined to form a tightly connected coupling of two adjacent plasti...

Abstract

A connecting method for the corner parts of plastic-steel door or window includes such steps as making L-shaped reinforcing parts, inserting at least one said reinforcing part into the cavities of adjacent plastic-steel sections, and filling adhesive in the space between them for adhering them together. Its advantages are high connection strength, rigidity and resistance to deformation, and easy operation.

Description

technical field [0001] The invention relates to a plastic-steel door and window, in particular to a connection method for the corner couple of the plastic-steel door and window. technical background [0002] Generally, the connection method of the corner joints of plastic doors and windows is to couple two adjacent plastic door and window frames or leaves together by means of external force. The part of the fan angle couple is usually welded (for plastic steel profiles) and screwed (for all plastic profiles). The plastic doors and windows made by these methods have poor deformation resistance, and the phenomenon of corner drop deformation often occurs. The plastic door and window frame described in CN2155424 in the Chinese Patent No. or fan angle coupling method is to adopt the joint of angle type to connect the two profiles to be butted, so that the four jiaos of the plastic door and window frame or fan have the same shape as the original The profiles are made of differen...
