Problems solved by technology

[0003] The corners of existing plastic-steel doors and windows are mostly connected by welding. The corners connected by welding are often less stable and prone to cracking. Moreover, as time goes by, the material will gradually age, and the corners The internal structure is prone to loosening, which reduces the service life of the overall doors and windows

Embodiment Construction

[0033] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0034] See Figure 1-9 A plastic steel door-to-corner connection structure, including the lateral frame rod 1 and the vertical frame rod 2, the lateral frame rod 1 is connected to the vertical frame rod 2 and forms a vertical angle in two connecting ends, the lateral frame rod 1 and vertical The frame rod 2 is a hollow rod member, and the lateral frame rod 1 and the vertical frame rod 2 each include two side walls 3, and the two side walls 3 are connected by one wall 4 and the second wall 5, two The side wall 3 is formed between the first wall 4 and the No. 1 wall 4; all of which are existing techniques, in the present invention, the first wall 4 is adjacent to the interior of the cavity to form a corner. The segment 6 and continues to extend forming a wall mounting section 7 and forms a mounting chamber 8 on a wall mounting section 7, which is conside...

Abstract

The invention discloses a corner connection structure of plastic-steel doors and windows, which comprises a transverse frame rod and a vertical frame rod on which a No. 1 wall is arranged. Continue to extend to form the No. 1 wall installation section and form an installation cavity in the No. 1 wall installation section, and also include a connection joint, the connection joint includes a horizontal connection end and a vertical connection end, and the ends of the horizontal connection end and the vertical connection end are both A locking mechanism is installed. Triple fixation is achieved at the corners of plastic-steel doors and windows through connecting joints. The first is the traditional welding connection, the second is the screw connection, and the third is the connection through the locking mechanism. The triple fixation ensures the overall connection effect very well. The setting of the locking mechanism ensures that the horizontal frame rod and the vertical frame rod can continue to be connected together and achieve good mutual sealing, avoid cracking and loosening at the joint, enhance the overall stability, and ensure the practical life of the overall door and window.

Description

Technical field [0001] The present invention relates to the field of production technology of plastic steel doors and windows, in particular, a plastic steel door angle portion connection structure and method. Background technique [0002] Plastic steel doors and windows are increasingly widely used in building installation projects, and plastic steel doors and windows are the main raw materials with polyvinyl chloride (UPVC) resins, plus a proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc. The profile is extruded, and then the door and window frame fan is made by cutting, welding or screwing. [0003] Most of the corners of the existing plastic steel doors and windows are mostly connected by welding. The corners of the welding method often have poor stability, which is easy to crack, and, with time, the material will gradually aging, angle The structure of the department is prone to peculum, which reduces the service life of the overall doors and windows....
