Description

Technical Field

[0001] The utility model relates to the field of door and window profiles, in particular to a multi-cavity heat-insulating metal door and window profile. Background Art

[0002] Doors and windows are the main structures for indoor light transmission and ventilation. The profile structures of existing doors and windows are diverse, mainly divided into plastic steel profiles and alloy profiles. Plastic steel profiles are mainly made of resin as the main raw material, with a certain proportion of stabilizers, colorants, fillers and other materials. They have the advantages of low price, good thermal insulation performance, good sound insulation effect, etc. However, the plastic steel profile is not hard enough, the surface is easily scratched, and it is easy to age. After the plastic steel profile is aged, the corner code of the corner assembly is difficult to ensure the airtightness of the doors and windows, and there are safety hazards; while the alloy profile is made of a variety of metal materials in a certain proportion, and has the advantages of high strength and good corrosion resistance, etc., but the high cost of the alloy profile and the high thermal conductivity make its installation process complicated. Therefore, a door and window profile with low comprehensive cost and easy installation is needed. Utility Model Content

[0003] The utility model aims to provide a multi-cavity heat-insulating metal door and window profile, which not only has the advantages of plastic-steel profiles and alloy profiles, but is also easy to install.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A multi-cavity heat-insulating metal door and window profile comprises a plastic-steel middle frame and an alloy gusset plate. The plastic-steel middle frame is in a rectangular shape. A plurality of parallel partitions with equal spacing are arranged in the middle of the plastic-steel middle frame. The plurality of partitions separate a plurality of cavities in the middle of the plastic-steel middle frame. Structural cavities for installing angle codes are reserved between the ends of both ends of the plastic-steel middle frame and the adjacent partitions. A hook group for installing pressure wires is processed on the outer wall of the plastic-steel middle frame on both sides of the structural cavity. The alloy gusset plates are installed at both ends of the plastic-steel middle frame. The cross-section of the alloy gusset plates is C-shaped or U-shaped. The ends of both ends of the alloy gusset plates are processed with hooks for hooking the plastic-steel middle frame.

[0006] The side wall of the alloy gusset plate is flush with the end surface of the plastic-steel middle frame.

[0007] The multi-cavity heat-insulating metal door and window profile provided by the utility model has the following beneficial effects:

[0008] (1) By installing alloy gussets at both ends of the plastic-steel middle frame, the wear resistance and corrosion resistance of the plastic-steel middle frame can be effectively improved, while also improving the appearance of the doors and windows. In addition, the broken bridge structure of the existing alloy doors and windows is eliminated, greatly improving the convenience of door and window installation;

[0009] (2) By processing several partitions in the middle of the plastic steel middle frame, the several partitions can not only improve the structural strength of the plastic steel middle frame, but also the separated cavities can be passed through steel wires to ensure the integrity of the doors and windows after assembly, which can effectively reduce safety hazards;

[0010] (3) The alloy gusset plate can ensure the integrity of the profile through the hooks at both ends. At the same time, the alloy gusset plate is flush with the end face of the plastic steel middle frame, which can meet the requirements of "horizontal and vertical" when installing doors and windows, thereby ensuring the beauty of the doors and windows after installation.

[0015] Example

[0016] like Figure 1 , Figure 2As shown, the multi-cavity heat-insulating metal door and window profile provided in the present embodiment includes a plastic-steel middle frame 1 and an alloy gusset plate 2. The plastic-steel middle frame 1 is in the shape of a rectangle. A plurality of parallel partitions 3 with equal spacing are arranged in the middle of the plastic-steel middle frame 1. The number of partitions 3 can be increased or decreased accordingly according to the size of the door and window to ensure the stability of the door and window profile. The width of the partition 3 corresponds to the short side size of the rectangular middle frame. The position of the partition 3 is opposite to the position of the glass. Therefore, the plurality of partitions 3 can also improve the structural strength of the plastic-steel middle frame 1. The plurality of partitions 3 separate a plurality of cavities 4 in the middle of the plastic-steel middle frame 1. Structural cavities 5 for installing corner codes are reserved between the ends at both ends of the plastic-steel middle frame 1 and the adjacent partitions 3. The structural cavities 5 are used at the corners when the doors and windows are assembled. The doors and windows are assembled into frame types by using corner codes, which belongs to the prior art and will not be described here. A hook group 7 for installing a pressure line 6 is processed on the outer wall of the plastic-steel middle frame 1 on both sides of the structural cavity 5. The pressure line 6 installed on the hook group 7 is used The invention is used for fixing glass or limiting the position of openable window sashes, and belongs to the prior art. The alloy gusset plate 2 is installed at both ends of the plastic-steel middle frame 1. After the profile is installed, the two ends of the plastic-steel middle frame 1 correspond to the indoor surface and the outdoor surface respectively. After the alloy gusset plate 2 is installed, the wear resistance and aging resistance of the profile are improved by utilizing its own material characteristics. In order to conveniently install the alloy gusset plate 2 on the plastic-steel middle frame 1, the cross-section of the alloy gusset plate 2 is C-shaped or U-shaped, and the ends of the two ends of the alloy gusset plate 2 are processed with hooks 8 for hooking the plastic-steel middle frame 1. The hooks 8 are used to hook the plastic-steel middle frame 1 to ensure the stability of the connection to avoid the high temperature in summer causing the alloy gusset plate 2 to absorb heat and separate from the plastic-steel middle frame 1. In order to ensure the consistency of the size of the profile, the side wall of the alloy gusset plate 2 is flush with the end face of the plastic-steel middle frame 1, that is, the two ends of the plastic-steel middle frame 1 need to reserve a space adapted to the thickness of the alloy gusset plate 2, so that after the alloy gusset plate 2 is installed, the outer wall of the alloy gusset plate 2 is flush with the inside and outside of the plastic-steel middle frame 1.

[0017] The method of using the utility model is:

[0018] During assembly, materials are cut according to the size of the doors and windows, and the profiles are spliced ​​into a frame shape through corner brackets. During the process of corner assembly, the profiles forming the frame can be connected by passing steel wires through the cavity 4. When installing the doors and windows, the two ends of the steel wires are fixed on the explosive bolts to deal with the damage to the doors and windows caused by excessive force on the corner brackets due to aging and deformation of the plastic steel middle frame 1 and strong winds, thereby effectively improving the safety factor of the profiles.

[0019] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
