Description

Technical Field

[0001] The utility model relates to the technical field of steel-plastic door and window profiles, in particular to a fireproof and energy-saving steel-plastic door and window profile. Background Art

[0002] Doors and windows are an important part of building construction, and their energy consumption accounts for about 30% of the overall energy consumption of the building. The traditional function of windows is to provide residents with light, vision and fresh air. With the rise of green buildings, future buildings have put forward more requirements on building doors and windows.

[0003] Traditional metal doors and windows have high thermal conductivity of their own materials and poor thermal insulation performance of profiles, resulting in low overall thermal insulation of doors and windows, which is not conducive to building energy conservation.

[0004] Therefore, it is necessary to provide a new fireproof and energy-saving steel-plastic door and window profile to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a fireproof and energy-saving steel-plastic door and window profile which has high thermal insulation and is beneficial to building energy conservation.

[0006] The utility model provides a fireproof and energy-saving steel-plastic door and window profile, including a PVC profile, wherein a special-shaped steel inner body is embedded in the PVC profile, a plurality of independent cavities are opened inside the PVC profile, a fireproof rubber strip installation groove is opened on the outside of the PVC profile, and the fireproof rubber strip is fixed in the fireproof rubber strip installation groove through a rubber surface.

[0007] In order to further improve the thermal insulation performance of PVC profiles, the utility model provides a fireproof and energy-saving steel-plastic door and window profile. Preferably, a foam layer is embedded in the interior of several of the cavities, and an insulation block is fixedly connected to the interior of the foam layer.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The fireproof and energy-saving steel-plastic door and window profile is made by adopting a steel-plastic co-extrusion process. The PVC profile and the special-shaped steel inner body do not need to be connected by an installation structure, but are directly and tightly combined. A fireproof rubber strip is fixed in the fireproof rubber strip installation groove, so that the fireproof rubber strip expands when heated and fills the combustion gap to prevent the PVC profile and the special-shaped steel inner body from being burned through. The multi-cavity structure can optimize the thermal conductivity of the profile, which is more energy-saving and environmentally friendly. The special-shaped steel inner body can ensure the strength of the PVC profile. At the same time, based on its special-shaped structure, it can improve the fire resistance, thereby making the PVC profile itself have higher thermal insulation properties, which is beneficial to building energy conservation, and solves the problem that the existing traditional metal doors and windows have low overall thermal insulation properties due to the high thermal conductivity of their own materials and poor thermal insulation properties of the profiles, which is not conducive to building energy conservation.

[0011] Including: 1. PVC profile; 2. Special-shaped steel inner body; 3. Cavity; 4. Fireproof rubber strip installation groove; 5. Foaming layer; 6. Insulation block. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0013] Reference Figure 1 A fireproof and energy-saving steel-plastic door and window profile, including a PVC profile 1, a special-shaped steel inner body 2 is embedded in the PVC profile 1, a plurality of independent cavities 3 are opened inside the PVC profile 1, a fireproof rubber strip installation groove 4 is opened on the outside of the PVC profile 1, and the fireproof rubber strip is fixed in the fireproof rubber strip installation groove 4 by a rubber surface. The PVC profile 1 and the special-shaped steel inner body 2 are made by a steel-plastic co-extrusion process. There is no need for an installation structure to connect the PVC profile 1 and the special-shaped steel inner body 2, and they are directly and tightly combined, so that the inner body can be made into a special shape. At the same time, the PVC profile can improve the corrosion resistance of the special-shaped steel inner body 2 on the outside. A fireproof rubber strip is fixed in the fireproof rubber strip installation groove 4, so that the fireproof rubber strip expands when heated and fills the combustion gap to prevent the PVC profile 1 and the special-shaped steel inner body 2 from burning through. By adopting a multi-cavity structure, the thermal conductivity of the profile can be optimized, which is more energy-saving and environmentally friendly. The special-shaped steel inner body 2 can ensure the strength of the PVC profile 1. At the same time, based on its special-shaped structure, it can improve the fire resistance, thereby making the PVC profile 1 itself have higher thermal insulation properties, which is beneficial to building energy saving.

[0014] Reference Figure 1 A foam layer 5 is embedded in several cavities 3, and an insulation block 6 is fixedly connected to the inside of the foam layer 5. Several cavities 3 are provided with foam layers 5 and insulation blocks 6, so that the insulation performance of a single cavity 3 is higher, thereby further improving the overall insulation performance of the PVC profile.

[0015] The implementation principle of a fireproof and energy-saving steel-plastic door and window profile in an embodiment of the utility model is as follows: the PVC profile 1 and the special-shaped steel inner body 2 are made by a steel-plastic co-extrusion process. There is no need for an installation structure to connect the PVC profile 1 and the special-shaped steel inner body 2, and they are directly and tightly combined, so that the inner body can be made special-shaped. At the same time, the PVC profile can improve the corrosion resistance of the special-shaped steel inner body 2 on the outside. A fireproof rubber strip is fixed in the fireproof rubber strip installation groove 4, so that the fireproof rubber strip expands when heated, fills the combustion gap, and prevents the PVC profile 1 and the special-shaped steel inner body 2 from burning through. By adopting a multi-cavity structure, the thermal conductivity of the profile can be optimized, which is more energy-saving and environmentally friendly. The special-shaped steel inner body 2 can ensure the strength of the PVC profile 1, and based on its special-shaped structure, it can improve the fire resistance, thereby making the PVC profile 1 itself have higher thermal insulation properties, which is beneficial to building energy saving.
