General mullion profile of composite material door and window and combined installation structure thereof

Abstract

This utility model discloses a universal mullion profile for composite material doors and windows and its combined installation structure. The universal mullion profile has a recessed positioning groove extending along its length on the side of the supporting cantilever away from the main support. Two rows of first connecting holes distributed along the length of the supporting cantilever are provided on the supporting cantilever. Therefore, the universal mullion profile can be used independently while meeting the designed structural strength requirements. When structural reinforcement profiles are required, they can be adaptively selected according to the deflection and deformation resistance requirements of mullions of different heights, reducing both the number and size of molds, thus significantly reducing development costs. Furthermore, because the structural reinforcement profiles can be flexibly selected, a narrower main support can be used, reducing the visible surface area of ​​the profile, increasing the light transmission ratio and enhancing aesthetics.

Description

Technical Field

[0001] This utility model relates to the field of composite material profile structure technology, specifically to a general mullion profile for composite material doors and windows and its combined installation structure. Background Technology

[0002] As people's requirements for room lighting increase, the ratio of window area to room size is constantly increasing. Please refer to Chinese utility model patent with publication number CN223089168U. Existing mullion profiles are mostly made of aluminum alloy. However, due to the excellent heat transfer performance of aluminum alloy profiles, they easily conduct indoor heat or cold to the outside, resulting in poor indoor thermal insulation performance.

[0003] Therefore, a type of window frame profile made of glass fiber composite material has emerged on the market. It not only has high structural strength, which can ensure reliable installation of glass, but also has excellent thermal insulation performance, which can effectively improve the thermal insulation effect of the house.

[0004] However, the applicant discovered in production practice that, for example Figure 1 The glass fiber composite mullion profile shown here requires a large-section reinforcing structure to be added to the outer side (outdoor side) of the mullion profile to meet the requirements for flexural deformation resistance. Because the reinforcing structure is quite wide on the visible surface of the profile, it not only affects the aesthetics but also the proportion of light transmission. Furthermore, to meet the requirements for flexural deformation resistance at different heights, different reinforcing structures are usually required, resulting in the need for numerous glass fiber composite molds for the mullion profile, leading to high mold-making costs.

[0005] Solving these problems is now a top priority. Utility Model Content

[0006] In view of this, the present invention provides a universal mullion profile for composite material doors and windows and its combined installation structure.

[0007] The technical solution is as follows:

[0008] The first aspect of this application relates to a general mullion profile for composite material doors and windows, comprising a mullion profile body, the mullion profile body including a main support portion and a support cantilever integrally formed vertically at one end of the main support portion, the main support portion and the support cantilever together forming a "T" shaped structure, the side of the support cantilever away from the main support portion having a recessed positioning groove extending along its length direction, the positioning groove being directly opposite the main support portion, the support cantilever having two rows of first connecting holes distributed along its length direction, the two rows of first connecting holes being symmetrically arranged on both sides of the main support portion.

[0009] The universal mullion profile for composite material doors and windows described above can be used independently without the need for structural reinforcement profiles, provided that the designed structural strength is met. When structural reinforcement profiles are required, the universal mullion profile can be reliably positioned with the structural reinforcement profile via positioning grooves, and then reliably fixed with the structural reinforcement profile using connectors through two rows of first connecting holes. This allows for the adaptive selection of structural reinforcement profiles based on the deflection and deformation requirements of mullions of different heights, reducing both the number and size of molds required and significantly lowering development costs. Furthermore, the flexible selection of structural reinforcement profiles allows for the use of narrower main support sections, reducing the visible surface area of ​​the profile and increasing both light transmission and aesthetics.

[0010] The second aspect of this application relates to a combined installation structure of the aforementioned general-purpose mullion profile, wherein a structural reinforcement profile with a rectangular tube column structure is provided on the side of the supporting cantilever away from the main support. A positioning boss with an embedded positioning groove is formed on the outer wall of the side wall of the structural reinforcement profile that abuts against the supporting cantilever. A second connecting hole is opened on the side wall of the structural reinforcement profile that abuts against the supporting cantilever, which communicates with each of the first connecting holes one by one. A rivet nut is passed through each of the first connecting holes and the corresponding second connecting hole. A bolt is threaded through each rivet nut and tightened thereon, thereby locking the structural reinforcement profile and the supporting cantilever into one unit.

[0011] The combined installation structure using the above-mentioned general-purpose mullion profiles not only possesses all the advantages of these profiles, but also ensures both ease of assembly and reliability through the use of rivet nuts and bolts for locking, resulting in durability.

[0017] Figure 6 This is a structural schematic diagram of Embodiment 5 of the present invention. Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0019] Example 1:

[0020] like Figures 2-6 As shown, a general mullion profile for composite material doors and windows mainly includes a mullion profile body 1. The mullion profile body 1 includes an integrally formed main support part 11 and a support cantilever 12. The support cantilever 12 is vertically arranged at one end of the main support part 11, so that the main support part 11 and the support cantilever 12 together form a "T" shaped structure, so that the mullion profile body 1 is similar to the existing mullion profile as a whole.

[0021] In this embodiment, a positioning groove 122 extending along its length is recessed on the side of the support cantilever 12 away from the main support portion 11. The positioning groove 122 is located at the middle position of the support cantilever 12, specifically, the positioning groove 122 is directly opposite the main support portion 11. Furthermore, two rows of first connecting holes 121a are provided on the support cantilever 12, distributed along its length, and the two rows of first connecting holes 121a are symmetrically arranged on both sides of the main support portion 11.

[0022] Therefore, when the structural strength requirement is met, this universal mullion profile does not need to be configured with structural reinforcement profile 2 and can be used directly and independently. When structural reinforcement profile 2 is required, the universal mullion profile can first achieve reliable positioning with the structural reinforcement profile 2 through the positioning groove 122, and then use the two rows of first connecting holes 121a to achieve reliable fixing with the structural reinforcement profile 2 using connectors. Thus, the structural reinforcement profile 2 can be adaptively selected according to the deflection and deformation requirements of mullions of different heights, which reduces the number of molds and the size of the molds, thereby significantly reducing development costs. Furthermore, since the structural reinforcement profile 2 can be flexibly selected, a narrower main support part 11 can be used, reducing the visible surface ratio of the profile, which increases the light transmission ratio and enhances aesthetics.

[0023] In this embodiment, the supporting cantilever 12 comprises two rectangular frame portions 121 symmetrically and integrally formed on both sides of the main support portion 11, compared to Figure 1 With its single-layer support cantilever, the rectangular frame portion 121 of this embodiment has significantly improved structural strength, thereby greatly enhancing the reliability of glass installation.

[0024] Furthermore, the same side of the two rectangular frame portions 121 protrudes from the end face of the main support portion 11, thereby jointly forming the aforementioned positioning groove 122. At the same time, a row of the aforementioned first connecting holes 121a distributed along its length direction is provided on the side wall of the two rectangular frame portions 121 protruding from the end face of the main support portion 11. Correspondingly, bolt through holes 121b are provided on the side wall of the two rectangular frame portions 121 opposite to the first connecting holes 121a, that is, each bolt through hole 121b is directly opposite to one of the first connecting holes 121a, and each bolt through hole 121b is coaxially arranged with the corresponding first connecting hole 121a. At the same time, the diameter of the bolt through hole 121b is larger than the diameter of the first connecting hole 121a, thereby ensuring the convenience of the connector installation.

[0025] Furthermore, each bolt through hole 121b is detachably equipped with a sealing element 123. By setting the sealing element 123, dust and foreign objects can be prevented from entering the bolt through hole 121b.

[0026] Example 2:

[0027] Please see Figure 3 In a combined installation structure of a general mullion profile according to Embodiment 1, a structural reinforcement profile 2 with a rectangular tube column structure is provided on the side of the support cantilever 12 away from the main support part 11. The structural reinforcement profile 2 abuts against the support cantilever 12. Furthermore, a positioning boss 21 is formed on the outer wall of the side wall of the structural reinforcement profile 2 that abuts against the support cantilever 12, which is adapted to the positioning groove 122. The positioning boss 21 is embedded in the positioning groove 122, ensuring reliable positioning of the general mullion profile and the structural reinforcement profile 2.

[0028] Meanwhile, on the side wall where the structural reinforcement profile 2 abuts against the supporting cantilever 12, there are second connecting holes 22 that communicate with each of the first connecting holes 121a. Each first connecting hole 121a and its corresponding second connecting hole 22 is fitted with a rivet nut 3, and each rivet nut 3 is threaded with a bolt 4 tightened onto it. Thus, the deformation of the rivet nut 3 locks the structural reinforcement profile 2 and the supporting cantilever 12 together. Specifically, the rivet nut 3 is first fixed to the first connecting hole 121a and the second connecting hole 22 using a rivet gun, and then the bolt 4 is screwed in for further tightening and reinforcement. Therefore, the method of using rivet nuts 3 in conjunction with bolts 4 for tightening ensures both ease of assembly and reliability, resulting in durability.

[0029] Furthermore, an elastic gasket 5 is provided at the bottom of the positioning groove 122, and the outer end face of the positioning boss 21 is supported on the elastic gasket 5. By providing the elastic gasket 5, the fit clearance tolerance between the general mullion profile and the structural reinforcement profile 2 can be eliminated. It should be noted that the elastic gasket 5 can be made of rubber or silicone, which is inexpensive and durable.

[0030] Example 3:

[0031] Please see Figure 4 The main structure of this embodiment is exactly the same as that of embodiment 2. The difference is that the structural reinforcing profile 2 is provided with a small reinforcing liner 6 in the form of a rectangular tube column. This is because glass fiber composite material has high longitudinal bending strength, but poor transverse bending strength and slightly weak elastic modulus. Therefore, by adding the small reinforcing liner 6, the problems of poor transverse bending strength and small elastic modulus of glass fiber composite material can be effectively overcome to meet the requirements of structural strength.

[0032] Specifically, on the inner walls of both sides of the structural reinforcement profile 2, near and away from the supporting cantilever 12, two reinforcing ribs 25 protrude and extend along their length. The four reinforcing ribs 25 are rectangularly distributed and symmetrically arranged in pairs on both sides of the extension line of the positioning boss 21. The small reinforcing rib 6 abuts against the side walls of the structural reinforcement profile 2 near and away from the supporting cantilever 12 and faces the main support part 11; that is, the small reinforcing rib 6 is located in the middle of the structural reinforcement profile 2. Simultaneously, the small reinforcing rib 6 is supported on the side wall of the four reinforcing ribs 25 near the extension line of the positioning boss 21; that is, the small reinforcing rib 6 is snapped onto the four reinforcing ribs 25, ensuring reliable installation of the small reinforcing rib 6.

[0033] Example 4:

[0034] Please see Figure 5 The main structure of this embodiment is exactly the same as that of embodiment 3, except that the smaller reinforcing liner 6 is replaced with a larger reinforcing liner 7 to meet higher structural strength requirements.

[0035] Therefore, on the inner walls of both sides of the structural reinforcement profile 2 without reinforcing ribs 25, there are protruding support bosses 23 extending along their length. The two support bosses 23 are symmetrically distributed on both sides of the extension line of the positioning boss 21. The large reinforcing rib 7 is also a rectangular tube column structure. Two of the opposite side walls of the large reinforcing rib 7 are supported on the end faces of the four reinforcing ribs 25, and the other two opposite side walls of the large reinforcing rib 7 are supported on the end faces of the two support bosses 23, ensuring the reliable installation of the large reinforcing rib 7.

[0036] Example 5:

[0037] Please see Figure 6 The main structure of this embodiment is exactly the same as that of embodiment 4, except that the large reinforcing liner 7 is replaced with a reinforcing connector 9 to further enhance the overall structural strength.

[0038] Specifically, each of the two supporting bosses 23 has a screw mounting groove 24 extending along its length on the outer wall of the structural reinforcement profile 2. The reinforcing connector 9 includes two reinforcing connecting plates 91 that abut against the end faces of the two supporting bosses 23, and a mounting connecting plate 92 that is fixedly connected to one or both ends of the structural reinforcement profile 2 by the two reinforcing connecting plates 91. The bottom of the two screw mounting grooves 24 is secured to the end face of the supporting bosses 23 by a number of screws 10. Therefore, the reinforcing connector 9 is completely and securely installed on the structural reinforcement profile 2 by the screws 10. Furthermore, the reinforcing connector 9 can be pre-installed into the structural reinforcement profile 2, thereby enabling rapid installation on site and facilitating adjustment of the three-dimensional accuracy of the installation.

[0039] Furthermore, decorative cover plates 8 can be detachably installed on the slots of both screw mounting grooves 24. After the installation of the reinforcing connector 9 is completed, the decorative cover plates 8 are placed on the slots of the screw mounting grooves 24 to prevent the screws 10 from being exposed, thus ensuring the overall aesthetics.

[0040] For Examples 2-5, the structural reinforcement profile 2 can be pre-installed on-site and its dimensions adjusted. Subsequently, the installation of doors and windows can be completed simply by matching the profile with the universal mullion with the structural reinforcement profile 2. In particular, the pre-installation of the structural reinforcement profile 2 can effectively avoid the risk of the entire window tilting to the outside when installing large windows, reducing the difficulty of installation and significantly reducing the risk of safety problems during the installation process.

[0041] In particular, the mounting connection plate 92 of embodiment 5 has several mounting holes 921, which makes it easier to install on the construction site in advance.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
