A plastic-steel window frame right-angle screw connection structure and its installation method

Abstract

The invention relates to a right-angle screwing connection structure of a plastic steel window frame and an installing method of the right-angle screwing connection structure. The right-angle screwing connection structure comprises a first plastic steel sectional material, a second plastic steel sectional material and a connecting element, wherein the first plastic steel sectional material and the second plastic steel sectional material are mutually vertical, the connecting element comprises an outer sheathing element, an inner embedding element and a steel inserting element, and the first plastic steel sectional material and the second plastic steel sectional material are fixedly and vertically connected into a whole through the connecting element. The right-angle screwing connection structure of the plastic steel window frame has the advantages that the connecting element is adopted at a connecting part of the window frame for realizing the combination and connection, the traditional welding mode is completely replaced, on one hand, the occurrence of aggregation is eliminated, the appearance effect of the plastic steel window frame is beautified, on the other hand, the plastic steel window frame can be combined and dismounted, in a special application scene, the plastic steel window frame can be dismounted for replacing the occupied physical space, and the transportation, the loading and the unloading are convenient. Meanwhile, the right-angle screwing connection structure of the plastic steel window frame has the advantages that the installation is convenient, the processing process is simple, the manufacturing and production cost is low, the effect is good, obvious social benefits and economic benefits are realized, and the right-angle screwing connection structure of the plastic steel window frame is worth of being popularized and applied.

Description

Technical field [0001] The invention relates to a right-angle screw connection structure of a plastic steel window frame and an installation method thereof, and belongs to the technical field of plastic steel door and window processing. Background technique [0002] Nowadays, plastic-steel doors and windows are widely used in engineering construction and daily life. In the processing of plastic-steel doors and windows, PVC profiles are generally welded at a 45° angle, but during the welding process, condensate will be generated at the weld joint. This kind of aggregate seriously affects the appearance of plastic steel doors and windows, and affects the installation of glass and door and window accessories. Generally, manufacturers will manually remove the aggregates produced. No matter which cleaning method is used, the weld joints of the plastic-steel profiles will leave scars, which seriously affects the overall aesthetics of the plastic-steel doors and windows and reduces cust...

Problems solved by technology

[0002] Nowadays, plastic-steel doors and windows are widely used in engineering construction and daily life. During the processing of plastic-steel doors and windows, PVC profiles are generally welded at a 45° angle. This aggregate seriously affects the appearance of plastic steel doors and windows, and affects the installation of glass and door and window accessories

Aiming at the condensate produced, the general manufacturer will use manual removal, and no matter which cleaning method is used, scars will be left at the weld joints of plastic-steel profiles, which seriously affects the overall aesthetics of plastic-steel doors and windows, and reduces customers' desire to buy

In addition, the welding strength of traditional PVC profiles is not high and is easy to twist, and is easily damaged when subjected to external forces. The connection strength and reliability of welded plastic-steel profiles cannot be reliably guaranteed

[0003] The existing welded plastic-steel doors and windows are fixedly connected and have a large shape, which cannot be quickly disassembled and installed. At the same time, the large-volume plastic-steel doors and windows bring inconvenience to the loading and unloading process and also bring difficulties to the transportation process. In addition to transportation costs, these problems of plastic steel doors and windows have not been better resolved. Therefore, it is necessary to design a plastic steel doors and windows that can be disassembled and assembled.
