Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an outdoor side structure for fireproof and heat-insulating doors and windows and thermal insulation doors and windows frame and sash profiles. Background Art

[0002] With the rapid development of the construction field, metal doors and windows have been widely used. Door and window frame profiles are usually made of metal profiles, and profile technology is constantly developing in line with people's needs.

[0003] According to the requirements of the new building code, especially for residential buildings, fire refuge rooms need to be set up. The exterior windows and interior doors of the refuge rooms need to meet Class A fire protection (i.e. fire resistance) performance. When there is a fire outside the refuge room, doors and windows are the main way for the fire to spread from the outdoors to the indoors. In order to improve the fire resistance of doors and windows and gain more time for rescue, and because of the usual energy-saving requirements for doors and windows, it is necessary to develop door and window frame and sash profiles that are both fireproof and heat-insulating.

[0004] Existing insulated door and window profiles all include an indoor part and an outdoor part that are relatively arranged. There is an insulated butt joint distance between the indoor part and the outdoor part, and they are connected by insulated materials to form an insulated bridge (i.e., a cold bridge). Most metal fireproof doors and windows have fireproof performance that meets the requirements but the thermal insulation performance does not meet the requirements, or thermal insulation performance that meets the requirements but the fireproof performance does not meet the requirements. The two cannot be taken into account at the same time.

[0005] Inventor Wang Kai applied for a utility model patent in 2021, with patent number 2021219672877, named fire-resistant insulation door and window frame and sash profiles and their composite structures.

[0006] Such as profile section Figure 1 , Figure 2 and Figure 3 As shown, the patent includes an outdoor profile body 1, the outer surface of the outdoor profile body 1 is snap-connected with a decorative pressing plate 2 (referred to as a heat insulation film cover in this patent), and a heat insulation film 3 made of a refractory material is pressed between the decorative pressing plate 2 and the outer surface of the outdoor profile body 1. In this patent, the decorative pressing plate 2 (heat insulation film cover) is provided with an acute-angle hook 4 at one end (the lower end of the cross-sectional view) (although the patent does not define it as an acute-angle hook 4, it is clearly visible in the attached drawings that it is an acute-angle hook 4, and the inventor originally designed it to be an acute-angle hook 4), and a barb 5 at the other end (the upper end of the cross-sectional view). Figures 1 to 3 The assembly process of the decorative pressing plate 2 in the patent is shown as follows: first Figure 1 In the operation, the heat insulation film 3 is attached to the outer surface of the outdoor profile body 1, and then the sharp-angle hook portion 4 of the decorative pressing plate 2 is aligned with the corresponding end of the outdoor profile; Figure 2The operation is to make the sharp-angle hook portion 4 of the decorative pressing plate 2 hook the matching end (the lower end of the cross-sectional view) of the outer surface of the outdoor profile; push the barb 5 at the other end of the decorative pressing plate 2 into the corresponding end of the card slot on the outer surface of the outdoor profile; finally, Figure 3 As shown, the barb 5 at the other end of the decorative pressing plate 2 is pushed into the slot at the corresponding end of the outer surface of the outdoor profile to complete the clamping and compounding work of the thermal insulation film 3, the decorative pressing plate 2 and the outdoor profile.

[0007] The decorative pressing plate 2 and the profile body 1 are about 6 meters long and need 2-3 people to manually assemble them, which is labor-intensive, time-consuming, labor-intensive and has low production efficiency.

[0008] If cold rolling technology can be used for mechanical cold rolling and compounding, the labor intensity will be greatly reduced and the production efficiency will be improved. However, the current structure of the decorative pressing plate 2 is difficult to use cold rolling technology because of the shape of the sharp-angle hook portion 4. It cannot be laid flat under the outer surface of the outdoor profile body 1 (the outer surface of the outdoor profile body 1 needs to be placed downward during cold rolling) for cold rolling processing, and mechanized and automated production cannot be achieved.

[0009] Therefore, it is necessary to design a new outdoor structure of the fireproof thermal insulation door and window frame sash profile so that the thermal insulation film cover can be conveniently laid flat under the outer surface of the outdoor profile body 1 for cold rolling and compounding. Utility Model Content

[0010] The utility model aims to provide an outdoor structure of a fireproof thermal insulation door and window frame and sash profile. The thermal insulation film cover plate can be laid flat on the lower surface of the outdoor profile body for cold rolling and compounding, providing a structural basis for realizing mechanized and automated production.

[0011] To achieve the above-mentioned purpose, the outdoor structure of the fireproof thermal insulation door and window frame and sash profile of the utility model includes an outdoor profile body, an insulation film is pasted on the outer surface of the outdoor profile body, an insulation film cover plate is connected to the outside of the insulation film, and both ends of the insulation film cover plate in the width direction are provided with obtuse-angled hooks. The insulation film cover plate is cold-rolled and compounded with the outdoor profile body and the insulation film through the obtuse-angled hooks at both ends in the width direction.

[0012] The utility model has the following advantages:

[0013] With the structure of the utility model, the heat insulation film cover plate and the outdoor profile body are rolled and locked, and the heat insulation film cover plate and the outdoor profile body are parallel to each other, which is convenient for mechanized and automated operation. The clearance between the edges of the profiles on both sides is controllable, and the composite accuracy of the profiles is more guaranteed than that of previous manual operations, which is convenient for the processing and manufacturing accuracy of finished doors and windows. Of course, the utility model used for thermal insulation doors and windows can improve the thermal insulation and fireproof performance of doors and windows, and meet the low-carbon energy-saving requirements for building structures.

[0014] The specific structural improvement of the utility model is that the heat insulation film cover plate is cold-rolled and compounded with the outdoor profile body and the heat insulation film through the obtuse hooks at both ends of the profile cross-section structure in the width direction. The biggest difference compared with the prior art (the inventor's 2021 patent) is that the heat insulation film cover plate can be laid flat on the outer surface of the outdoor profile body and under the heat insulation film (when cold rolling, the outer surface of the outdoor profile body is set downward) for cold rolling, while in the prior art, since the two ends of the decorative pressing plate cross-section in the width direction are sharp-angled hooks and barbs, they can only be cold rolled manually. Figures 1 to 3 The elastic pressing operation in the process is difficult to achieve mechanization and automation, and the work efficiency is low. Even if the operation can be completed manually, the elastic arm of the hook at one end of the insulation film cover is too short, and the design accuracy of the elastic gap is difficult to control. If the gap is large, the decorative pressing plate is easy to crack and fall off after the profile is composited. If the gap is small, the edge of the insulation film will be completely cut off due to the shear effect of the hook during elastic pressing, causing the linear edge of the profile body to be connected to the metal of the linear edge of the decorative cover, forming a heat bridge and losing the heat insulation. At the same time, the outer side of the profile body and the inner side of the decorative cover are not firmly fitted, affecting the processing accuracy of doors and windows.

[0015] In short, the structure of the utility model provides convenience for mechanized or automated cold rolling processing, which can not only ensure that the insulation film cover plate is firmly composited with the insulation film and the outdoor profile body, but also avoid the insulation film being cut to form internal and external metal connections that cause heat conduction, and can reduce labor intensity and improve production efficiency through mechanized or automated cold rolling processing.

[0016] Thermal break doors and windows have been increasingly widely used in recent years because their profiles can effectively block internal and external heat conduction. Applying the new outdoor structure of the fire-resistant thermal break door and window frame and sash profiles to thermal break doors and windows is equivalent to adding a fireproof thermal break bridge to the profiles, which can significantly improve the thermal insulation and fire resistance of thermal break doors and windows.

DETAILED DESCRIPTION

[0034] like Figures 5 to 16 As shown, the outdoor structure of the fireproof thermal insulation door and window frame and sash profile of the utility model includes an outdoor profile body 1, an insulation film 3 is pasted on the outer surface of the outdoor profile body 1, the insulation film 3 is connected to the outside with an insulation film cover plate 6, and both ends of the insulation film cover plate 6 in the width direction are provided with obtuse-angled hooks. The insulation film cover plate 6 is cold-rolled and compounded with the outdoor profile body 1 and the insulation film 3 through the obtuse-angled hooks 7 at both ends in the width direction.

[0035] The specific cross-sectional structural improvement of the present invention is that the heat insulation film cover plate 6 is cold-rolled and compounded with the outdoor profile body 1 and the heat insulation film 3 through the obtuse-angled hooks 7 at both ends in the width direction. Specifically, both ends of the heat insulation film cover plate 6 in the width direction are provided with obtuse-angled hooks 7. The biggest difference compared with the prior art (the inventor's 2021 patent) is that the heat insulation film cover plate 6 can be laid flat on the outer surface of the outdoor profile body 1 and under the heat insulation film 3 (during the cold rolling process, the outer surface of the outdoor profile body 1 is set downward) for cold rolling, while in the prior art, since the two ends of the decorative pressing plate 2 in the width direction are sharp-angled hooks and barbs, they must be manually cold-rolled. Figures 1 to 3 The buckling action in the cold rolling process cannot complete this complex operation of laying the decorative pressing plate 2 (corresponding to the thermal insulation film cover plate 6 in this patent) flat under the outer surface of the outdoor profile body 1.

[0036] In short, the structure of the utility model provides convenience for cold rolling processing, which can not only ensure that the insulation film cover plate 6 is firmly combined with the insulation film 3 and the outdoor profile body 1, but also reduce labor intensity and improve production efficiency through cold rolling processing.

[0037] When cold rolling the outdoor structure of the fireproof thermal insulation door and window frame fan profile, a rolling film laminating machine and a rolling composite machine can be used to complete the cold rolling process. The two machines are arranged along the length direction of the outdoor structure of the fireproof thermal insulation door and window frame fan profile according to the length of the profile.

[0038] The first roller laminating machine includes two upper pressing wheel groups 10 and two bottom rollers 11;

[0039] The second rolling composite machine includes an upper pressure wheel group 10, left and right side rolling wheels 12 and a lower roller 11. 10~12 are a wheel group. Three groups are arranged at intervals on the same machine. The left and right side rolling wheels 12 are usually active wheels, and the rest are passive wheels.

[0040] The first step of cold rolling is to paste the thermal insulation film. Figure 5 As shown, the heat insulation film 3 with adhesive backing is rolled and pasted on the outer surface of the outdoor profile body 1, and the outer surface of the outdoor profile body 1 and the heat insulation film 3 are placed downward on the bottom roller 11 of the first rolling machine, and the first upper pressing wheel group 10 of the rolling machine rolls downward on the outdoor profile body 1. As the film laminating machine runs, the upper two pressing wheel groups 10 and the bottom two rollers 11 laminarize the heat insulation film 3 with adhesive backing and the outdoor profile body 1, and then add the heat insulation film cover plate 6 at the bottom and transport it forward to the second rolling laminating machine.

[0041] The second step of cold rolling is rolling and locking the heat insulation film cover plate 6. The three wheel groups of the rolling and laminating machine are arranged at appropriate intervals, and the upper pressing wheel 10 and the lower supporting roller 11 roll and clamp the outer side profile body 1 of the room and the heat insulation film 3 and the heat insulation film cover plate 6 to align the layers ( Figure 6 The left and right spacing of the left and right rolling wheels of the three-wheel group gradually tightens the obtuse hooks on both sides of the thermal insulation film cover plate 6 to complete the composite of the outer profile of the frame and fan ( Figure 7 As shown). The heat insulation film cover plate has sheet and tube shapes, and the composite processing principle is the same. This specification describes the sheet heat insulation film cover plate 6.

[0042] The utility model can be used for the finished product processing of normal temperature thermal insulation doors and windows, such as Figures 8 to 10 As shown, the frame and sash profile of the normal temperature thermal insulation door and window includes an indoor side profile body 8 and an outdoor side structure of the fireproof thermal insulation door and window frame and sash profile, and the outdoor side profile body 1 of the outdoor side structure of the fireproof thermal insulation door and window frame and sash profile is connected to the indoor side profile body 8 through a thermal insulation strip 9. The thermal insulation strip 9 is a nylon strip (existing technology).

[0043] The utility model can be used on high temperature fireproof (ie fire-resistant) thermal insulation doors and windows, and can also be used on normal temperature (ie ordinary) thermal insulation doors and windows. The difference is:

[0044] 1. Used for fireproof bridge insulation door and window profile structure such as Figure 4 As shown, the outdoor composite structure 13 of the fireproof thermal insulation door and window frame and the indoor profile body 8 is filled with a fire-resistant connecting body 14 formed by curing inorganic refractory slurry, that is, Figure 4 The honeycomb structure is suitable for high temperature environments below 800℃ outdoors. The profile fire rating can reach A2 after testing (after the outer side of the profile withstands open flames for 2 hours, water dripping from the inner side of the profile body does not evaporate, proving that the temperature rise is less than 100℃), fully demonstrating its fire resistance and heat insulation properties.

[0045] 2. If Figures 8 to 10 As shown, the frame and sash profile of the common thermal-break heat insulation door and window includes an indoor structure and an outdoor structure. The outdoor profile body 1 and the indoor profile body 8 of the outdoor structure of the common thermal-break heat insulation door and window frame and sash profile are connected by nylon insulation strips (i.e., thermal-break heat insulation strips 9), forming the finished main profile of the utility model. The existing common thermal-break heat insulation door and window profiles are affected by the temperature resistance limit of the nylon strips and are only suitable for temperature environments below 200°C, and the fire protection level can only reach Class B. With the addition of the outdoor heat insulation film structure of the utility model, it can block more than 70% of the outdoor high temperature. After testing, the profile fire protection level can reach Class A0.5 (the nylon insulation strip does not soften after the outer side of the profile withstands open flames for 0.5 hours), proving the effective heat insulation of the insulation film on the outer side of the profile, which is something that the common thermal-break heat insulation profile cannot do.

[0046] The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
