Description

Technical Field

[0001] The utility model relates to the technical field of composite doors and windows, in particular to a polyurethane-aluminum composite door and window. Background Technique

[0002] At present, the common polyurethane profile doors and windows in China mainly include two categories: aluminum alloy composite polyurethane profiles and glass fiber polyurethane profiles.

[0003] The main principle of the aluminum alloy composite polyurethane profiles is as follows: glass fiber reinforced polyurethane composite heat insulation strips are used to replace the traditional PA66 material heat insulation strips to make broken bridge aluminum profiles. The glass fiber reinforced polyurethane composite heat insulation strip has better heat preservation and flame retardant properties, and has good prospects in the field of fireproof windows. However, this type of profile also has obvious disadvantages.

[0004] 1. The linear expansion coefficients of aluminum and glass fiber polyurethane are quite different, and there is a risk of deformation of the doors and windows during long-term use.

[0005] 2. The strengths of aluminum and glass fiber polyurethane are different. When cutting the materials, the parameter settings (rotation speed, saw blade material, etc.) of the cutting saw cannot meet the cutting requirements of both materials at the same time, which is likely to cause uneven cut surfaces and affect the cutting and assembly accuracy.

[0006] The glass fiber polyurethane profile is a single-material profile, and its production and processing principle is similar to that of the fiberglass profiles currently produced by the company. Its main physical properties are better than those of fiberglass, but the anti-aging performance of this material is relatively poor and it cannot be exposed to ultraviolet rays for a long time. As a building maintenance component, doors and windows are exposed to sunlight for a long time. Directly applying glass fiber polyurethane to exterior windows will pose a greater hidden danger. Content of the Utility Model

[0007] The purpose of the utility model is to provide a polyurethane-aluminum composite door and window to solve the technical problems mentioned in the conventional background technique.

[0008] To solve the above technical problems, the utility model adopts the following technical solutions:

[0009] The utility model provides a polyurethane-aluminum composite door and window, including an aluminum profile and a polyurethane profile for forming the door and window profile;

[0010] Wherein, the aluminum profile and the polyurethane profile are connected by fasteners.

[0011] Further, the polyurethane profile is a glass fiber reinforced polyurethane profile.

[0012] Still further, the polyurethane profile includes two polyurethane split structures, and the two polyurethane split structures are connected by an extended sealing strip;

[0013] A sealing strip is also provided at the contact of the two polyurethane profile parts.

[0014] Furthermore, nail line positioning grooves are respectively provided on the upper top surfaces of the two polyurethane split structures, and a plurality of fasteners are evenly spaced on the nail line positioning grooves; the fasteners are fasteners arranged in the nail line positioning grooves through screws, and insertion grooves are formed on the side edges thereof.

[0015] Furthermore, the aluminum profile includes two aluminum split profiles respectively arranged above the two polyurethane profile parts;

[0016] A sealing strip is also provided between the two aluminum split profiles;

[0017] A reserved groove adapted to be inserted with the fastener is formed in the aluminum split profile.

[0018] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0019] In this application, the composite profile uses aluminum outdoors and fiberglass polyurethane as the main indoor material. The aluminum outdoors avoids direct sunlight on the polyurethane profile, preventing its rapid aging, which can enhance the durability of the window. Indoors, fiberglass polyurethane is used, effectively improving the overall heat insulation performance, and the heat transfer coefficient can be further reduced by filling heat insulation materials in its cavity. In addition, a snap-in process is used to connect the profiles of the two materials inside and outside. A nail line positioning groove is reserved on the fiberglass polyurethane profile, and the snap is mechanically fixed on the nail line in the form of points with screws, and then the aluminum profile is buckled on the fastener. The fastener can be rotated and tightened to lock the aluminum, so that the inner and outer profiles form an integral body, effectively avoiding the deformation problem of the doors and windows caused by different linear expansion coefficients of the two materials, and also avoiding direct contact between the aluminum and the fiberglass-reinforced polyurethane, enhancing the heat insulation performance.

[0026] Wherein the aluminum profile 1 and the polyurethane profile 3 are connected by a fastener 2.

[0027] In this embodiment, the polyurethane profile 3 is a glass fiber reinforced polyurethane profile.

[0028] During specific implementation, as Figure 1 shown, the polyurethane profile 3 includes two polyurethane split structures, and the two polyurethane split structures are connected by an extended sealing strip 6; wherein a sealing strip 5 is also installed at the contact position of the two polyurethane split profiles.

[0029] In this embodiment, nail line positioning grooves 31 are respectively preset on the upper top surfaces of the two polyurethane split structures, and a plurality of fasteners 2 are evenly spaced and installed on the nail line positioning grooves 31; the fasteners 2 are fasteners arranged in the nail line positioning grooves 31 by screws, and insertion grooves are symmetrically opened on the side thereof.

[0031] The design principle in this embodiment:

[0033] Among them, the glass fiber reinforced polyurethane profile is located on the indoor side, which is the main stress-bearing structure and functional structure of the profile, providing the overall strength of the profile. It itself has a very low heat transfer coefficient and is an important guarantee for the heat insulation performance of the doors and windows;

[0034] The aluminum profile is located on the outdoor side, which is not the main stress-bearing structure, protects the indoor glass fiber reinforced polyurethane profile, and at the same time plays a role in limiting the glass;

[0035] The fastener mainly connects the glass fiber reinforced polyurethane profile and the aluminum profile.

[0036] In the composite profile of this embodiment, aluminum is used outdoors and the main indoor material is glass fiber polyurethane. The aluminum outdoors avoids direct sunlight on the polyurethane profile, preventing its rapid aging, enhancing the durability of the window. Glass fiber polyurethane is used indoors, effectively improving the overall heat insulation performance, and the heat transfer coefficient can be further reduced by filling heat insulation materials in its cavity.

[0037] In addition, a snap - on process is used to connect the profiles of the two materials inside and outside. A nail - line positioning groove is reserved on the glass fiber polyurethane profile, and the snap - fastener is mechanically fixed to the nail - line in the form of points with screws ( Figure 3 ), then the aluminum profile 1 is buckled on the fastener 2, and the fastener 2 can be rotated and tightened to lock the aluminum profile 1, thus making the inner and outer profiles form an integral whole, effectively avoiding the problem of window deformation caused by different linear expansion coefficients of the two materials, and also avoiding direct contact between the aluminum profile 1 and the glass fiber reinforced polyurethane 3, enhancing the heat insulation performance.

[0038] In this embodiment, a drain hole is provided on the bottom side wall of the aluminum profile 1 on the window frame.

[0039] The above embodiments only describe the preferred ways of the present invention - creation, and do not limit the scope of the present invention.
