Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to PVC doors and windows with internal reinforcing ribs. Background Technology
[0002] PVC windows and doors are made primarily of polyvinyl chloride resin, which is extruded into profiles and then assembled by cutting, welding, or bolting. Steel linings are added inside the profile cavities to enhance rigidity. With their superior performance and beautiful appearance, PVC windows and doors are an indispensable part of modern architecture.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] In the use of existing PVC windows and doors, the window frame is in direct contact with the outside. After being exposed to wind and sun for a long time, the outer layer of PVC resin in the window frame is prone to weathering and aging, causing cracks at the corners of the window frame and a short service life. In addition, in windy weather, ordinary PVC profiles are easily deformed by strong winds, resulting in low overall structural strength. Utility Model Content
[0005] The purpose of this invention is to provide PVC windows and doors with internal reinforcing ribs to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVC window with internal reinforcing ribs, including a window frame, a window sash installed inside the window frame, the window sash being connected to the inner glass layer via an anti-slip strip, a reinforcing mesh being provided inside the window frame, the inner sidewall of the window frame being connected to the outer sidewall of the steel lining, and reinforcing angle steel being placed inside the window frame.
[0007] More preferably, the window frame has multiple cavities inside, and the inner wall of one of the cavities inside the window frame has a protrusion.
[0008] More preferably, a sealing strip is provided between the window sash and the inner glass.
[0009] More preferably, a sealing strip is provided between the anti-slip strip and the inner glass, and the anti-slip strip is engaged with the strip groove on the inner side wall of the window sash by an L-shaped clip on the side wall.
[0010] More preferably, the reinforcing mesh is disposed in the inner layer of the window frame to form an integral structure with the window frame.
[0011] More preferably, the sidewall of the steel liner has a groove that matches the protrusion inside the window frame cavity, and the steel liner is movably engaged with the protrusion inside the window frame cavity through the groove of the sidewall.
[0012] More preferably, the reinforcing angle steel is disposed inside the corner of the window frame, and both ends of the reinforcing angle steel are welded to the steel lining inside the window frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This PVC window and door features a reinforcing mesh inside the window frame, creating an integrated structure between the outer frame and the inner mesh. The inner mesh effectively counteracts the stress caused by the expansion and contraction of the frame due to temperature changes, preventing cracking. Furthermore, reinforcing angle steel is installed at the corners of the window frame, enhancing its overall structural strength and ensuring sufficient resilience against external forces such as strong winds, preventing deformation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 5This utility model provides a technical solution: a plastic steel door and window with internal reinforcing ribs, including a window frame 1, a window sash 2 installed inside the window frame 1, the window sash 2 being connected to the inner glass 4 via an anti-slip strip 3, a reinforcing rib mesh 5 being provided inside the window frame 1, the inner side wall of the window frame 1 being connected to the outer side wall of the steel lining 6, and a reinforcing angle steel 7 being placed inside the window frame 1.
[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the window frame 1 has multiple cavities inside, and the inner wall of one of the cavities inside the window frame 1 has a protrusion.
[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sealing strip is provided between the window sash 2 and the inner glass 4.
[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sealing strip is provided between the anti-slip strip 3 and the inner glass 4. The anti-slip strip 3 is engaged with the strip groove on the inner side wall of the window sash 2 by the L-shaped clip on the side wall.
[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the reinforcing mesh 5 is set in the inner layer of the window frame 1 to form an integral structure with the window frame 1.
[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the side wall of the steel liner 6 has a groove that matches the protrusion inside the cavity of the window frame 1. The steel liner 6 is movably engaged with the protrusion inside the cavity of the window frame 1 through the groove of the side wall.
[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the reinforcing angle steel 7 is installed inside the corner of the window frame 1, and both ends of the reinforcing angle steel 7 are welded to the steel lining 6 inside the window frame 1.
[0029] As in the process Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 5 As shown, this PVC-U door and window with internal reinforcing ribs operates as follows during use:
[0030] Firstly, the inner glass 4 is fitted with sealing strips between itself and the anti-slip strip 3 and the window sash 2, which can ensure the sealing effect between the inner glass 4 and the window sash 2. By adding a reinforcing mesh 5 to the inner layer of the window frame 1, the window frame 1 and the internal reinforcing mesh 5 form an integral structure. The internal reinforcing mesh 5 can effectively offset the stress generated by the expansion and contraction of the window frame 1, effectively preventing the window frame 1 from cracking. Furthermore, the steel lining 6 inside the window frame 1 and the reinforcing angle steel 7 at the corners can effectively improve the overall structural strength of the window frame 1.
