Description

Technical Field

[0001] This utility model relates to the field of curtain wall profile technology, and in particular to a frame structure for a fully enclosed curtain wall profile. Background Technology

[0002] Fully enclosed curtain wall profiles are core components commonly used in building curtain wall projects. They refer to profiles with a fully enclosed hollow cross-section. They are typically used to build the frame of the curtain wall and undertake functions such as glass fixing, load transfer, and sealing and insulation. By being fully enclosed, they solve the pain points of traditional open profiles in terms of strength, insulation, and waterproofing, and are one of the mainstream choices for high-end building curtain walls.

[0003] In existing technologies, four frame profiles are typically connected end-to-end. Corner brackets are inserted into the cavities of adjacent frame profiles, and then screws are driven in to form a closed rectangular frame. The interior of the rectangular frame is connected to the curtain wall glass via sealing strips. While this frame structure is easy to assemble, it requires screws to fix the corner brackets to the frame profiles. However, this method is a mechanical splicing, and gaps exist between the corner brackets and the profiles, which can easily lead to air leakage and water seepage. These gaps can also become thermal bridges, compromising the thermal insulation of the curtain wall. Furthermore, drilling holes at both ends of each frame profile damages the frame structure, reducing its stability. In addition, exposed screws affect the overall aesthetics of the frame. Moreover, the thermal insulation performance of the frame composed of these profiles is limited.

[0004] Therefore, it is necessary to improve the frame structure composed of fully enclosed curtain wall profiles in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects existing in the prior art and provide a frame structure for a fully enclosed curtain wall profile that ensures structural stability and aesthetics while improving thermal insulation performance.

[0006] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a frame structure for a fully enclosed curtain wall profile, comprising: A frame assembly for fixed installation within a wall opening comprises four frame profiles connected end-to-end, two extending horizontally and the remaining two extending vertically. Each frame profile has a cavity extending along its length, comprising a primary load-bearing cavity and an auxiliary cavity spaced apart. The cross-sectional area of ​​the primary load-bearing cavity is larger than that of the auxiliary cavity. The primary load-bearing cavities of the four frame profiles are connected end-to-end to form a rectangular load-bearing filling cavity, and the auxiliary cavities are connected end-to-end to form a rectangular auxiliary filling cavity. The auxiliary filling cavity is located inside the load-bearing filling cavity. Two frame profiles each have an opening communicating with their own primary load-bearing cavity, one for injecting polyurethane insulation casting adhesive and the other for evacuating air. An angle bracket assembly includes load-bearing angle brackets that are correspondingly disposed between two adjacent frame profiles. The load-bearing angle brackets are hollow angle brackets and their two ends are respectively sealed and connected to the circumferential cavity walls of the main force-bearing cavities of the two corresponding frame profiles. The curing frame is formed by curing polyurethane heat-insulating casting adhesive injected and cooperating with the corner bracket assembly to fill the stress-filled cavity.

[0007] Preferably, in order to facilitate the filling of the entire stress-bearing cavity by liquid polyurethane thermal insulation casting adhesive, the two openings are respectively provided on two frame profiles located at the bottom and the top, both extending in the horizontal direction, and the lower opening is used for injecting polyurethane thermal insulation casting adhesive.

[0008] Preferably, in order to further promote the filling of the entire stress-bearing cavity by the polyurethane insulation casting adhesive, the centerline of the opening is located in the middle of the corresponding frame profile.

[0009] Preferably, to ensure aesthetics, the two openings are respectively an injection hole and an air extraction hole, with the injection hole located on the bottom surface of the corresponding frame profile and the air extraction hole located on the top surface of the corresponding frame profile.

[0010] Preferably, to facilitate glue injection and air extraction, both openings are stepped holes, including a fine hole portion connected to the wall of the main force-bearing cavity and a coarse hole portion connected to the outer surface of the frame profile, wherein the inner diameter of the coarse hole portion is larger than the inner diameter of the fine hole portion.

[0011] Preferably, in order to ensure the structural strength of the opening position, the stepped hole is connected to an assembly tube, the outer circumferential edge of the assembly tube is sealed and fitted with the inner circumferential wall of the fine hole, one end of the assembly tube extends into the corresponding main force-bearing cavity, and the outer circumferential edge of the other end is provided with a flange, the flange is received in the coarse hole and fits with the bottom of the coarse hole.

[0012] Preferably, in order to ensure the sealing of the opening, a sealant cap is also included. The sealant cap cooperates with the flange to fill the coarse hole. The sealant cap is cured by a curing adhesive and is flush with the end of the coarse hole away from the fine hole.

[0013] Preferably, in order to enhance the connection strength between the curing frame and the assembly tube, a reinforcing hole is provided on the side wall of the assembly tube away from the flange, and the two ends of the reinforcing hole extend to the inner circumferential wall and the outer circumferential edge of the assembly tube, respectively.

[0014] Preferably, in order to ensure a firm connection between two adjacent frame profiles, the wall thickness of the load-bearing angle bracket is greater than the wall thickness of the frame profile.

[0015] Preferably, in order to enhance the thermal insulation performance of the frame structure, the auxiliary cavity is filled with an auxiliary thermal insulation strip.

[0016] In summary, compared with the prior art, the frame structure of the fully enclosed curtain wall profile of this utility model, by setting openings on two of the frame profiles, facilitates air extraction and glue injection. The injected polyurethane thermal insulation casting glue fills the main load-bearing cavity and the load-bearing corner bracket of the frame profile and then cures to form a cured frame, connecting the frame profile and the load-bearing corner bracket into one unit. This ensures the stability of the frame structure without the need for screw fixing that would damage the structure, and the thermal insulation is enhanced by the cured frame.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figures 1-9 As shown, the frame structure of a fully enclosed curtain wall profile according to this utility model includes: The frame assembly, used for fixed installation in the wall opening 71 of the wall 7, includes four frame profiles 1 connected end to end, two of which extend horizontally and the remaining two extend vertically. Each frame profile 1 is provided with a cavity extending along its own length. The cavity includes a main load-bearing cavity 11 and an auxiliary cavity 12 spaced apart. The cross-sectional area of ​​the main load-bearing cavity 11 is larger than the cross-sectional area of ​​the auxiliary cavity 12. The main load-bearing cavities 11 of the four frame profiles 1 are connected end to end to form a rectangular load-bearing filling cavity. The auxiliary cavities 12 are connected end to end to form a rectangular auxiliary filling cavity. The auxiliary filling cavity is located inside the load-bearing filling cavity. Two of the frame profiles 1 are respectively provided with an opening 13 that communicates with their own main load-bearing cavity 11. One is used for injecting polyurethane heat insulation casting adhesive, and the other is used for air extraction. The corner bracket assembly includes load-bearing corner brackets 2 that are correspondingly disposed between two adjacent frame profiles 1. The load-bearing corner brackets 2 are hollow corner brackets and their two ends are respectively sealed to the circumferential cavity walls of the main force-bearing cavity 11 of the corresponding two frame profiles 1. The curing frame 3 is formed by curing polyurethane heat-insulating casting adhesive injected and cooperating with the corner code assembly to fill the stress-bearing cavity.

[0020] The frame structure of this utility model is a rectangular frame in general. The lengths of the two horizontal frame profiles 1 are shorter than the lengths of the other two vertical frame profiles 1. In the frame of the assembled profiles, the auxiliary cavity 12 is located on the inner side near the wall opening 71, and the main load-bearing cavity 11 is located on the side near the inner wall of the wall opening 71. The load-bearing angle bracket 2 is L-shaped, and its two ends are respectively sealed and fitted to the inner walls of the main load-bearing cavities 11 of the two adjacent frame profiles 1. The load-bearing angle bracket 2 is a hollow angle bracket, that is, the load-bearing angle bracket 2 is provided with an L-shaped channel. The two ends of the channel are respectively located in the main load-bearing cavities 11 of the two adjacent frame profiles 1, ensuring that the two main load-bearing cavities 11 are interconnected. Thus, when the four frame profiles 1 are connected by the four load-bearing angle brackets 2, the four main load-bearing cavities 11 are connected end to end in sequence to form the load-bearing filling cavity of the rectangular frame structure, and the remaining four auxiliary cavities 12 are connected end to end in sequence to form the auxiliary filling cavity of the rectangular frame structure.

[0021] Unlike existing technologies, the frame structure of this utility model only requires openings 13 on two of the frame profiles 1, reducing the damage to the frame profile 1 structure and ensuring the overall structural strength of the frame. After the four frame profiles 1 are assembled with four load-bearing corner brackets 2, air is drawn out from one of the openings 13, creating a negative pressure inside the load-bearing cavity. Polyurethane heat-insulating casting adhesive is then injected into the load-bearing cavity, filling the internal channels of the main load-bearing cavity 11 and the load-bearing corner brackets 2. Finally, it is cured to form a cured frame 3. During the curing process, the four frame profiles 1 and the four load-bearing corner brackets 2 are fixedly connected, eliminating the need for screws. This further reduces the damage to the frame structure and enhances the stability of the frame structure. At the same time, the cured frame 3, cured by polyurethane heat-insulating casting adhesive, enhances the thermal insulation performance of the frame structure.

[0022] like Figure 8 and Figure 9 As shown, the frame profile 1 is also integrally formed with an assembly groove 14 and an assembly protrusion 15 extending along its length and located on the same side. The assembly protrusion 15 is correspondingly provided with the auxiliary cavity 12, and the assembly groove 14 is correspondingly provided with the main force-bearing cavity 11. The assembly protrusion 15 is used to connect the PA66 sealing strip to facilitate the frame to maintain a sealed connection with the glass. The assembly groove 14 is used to connect other profiles to form a complete curtain wall structure.

[0023] A further improvement is that two openings 13 are respectively provided on the two frame profiles 1 located at the bottom and the top, both extending in the horizontal direction. The lower opening 13 is used to inject polyurethane thermal insulation casting adhesive.

[0024] With this design, before applying the adhesive, air is first drawn from the main load-bearing cavity 11 of the top frame profile 1, and then adhesive is applied from the main load-bearing cavity 11 of the bottom frame profile 1. Under negative pressure, the polyurethane insulation casting adhesive can easily fill the load-bearing cavity, enhancing the thermal insulation performance while strengthening the connection structure between the frame profile 1 and the load-bearing corner bracket 2, thereby ensuring the stability of the entire frame structure.

[0025] A further improvement is that the centerline of the opening 13 is located in the middle of the corresponding frame profile 1.

[0026] The above design ensures that the polyurethane insulation casting adhesive can be evenly filled into the entire stress-bearing cavity during injection, thereby enhancing the overall structural strength of the frame structure.

[0027] A further improvement is that the two openings 13 are respectively an injection hole and an air extraction hole. The injection hole is located on the bottom surface of the corresponding frame profile 1, and the air extraction hole is located on the top surface of the corresponding frame profile 1. In this way, when the frame structure is assembled and installed in the wall opening 71 of the wall 7, the positions of the two openings 31 can be covered by the top and bottom inner walls of the wall opening 71, so that there is no obvious structural damage on both sides of the entire frame structure, thus ensuring the aesthetics of the frame structure.

[0028] A further improvement is that both openings 13 are stepped holes, including a narrow opening 131 connected to the wall of the main load-bearing cavity 11 and a wide opening 132 connected to the outer surface of the frame profile 1. The inner diameter of the wide opening 132 is larger than that of the narrow opening 131. During glue injection and air extraction, the end of the pipe can be placed against the bottom of the wide opening 132, and the pipe can communicate with the inner cavity through the narrow opening 131, facilitating air extraction and glue injection.

[0029] A further improvement is that the stepped hole is connected to an assembly tube 4, the outer circumferential edge of the assembly tube 4 is sealed and fitted with the inner circumferential wall of the fine hole portion 131, one end of the assembly tube 4 extends into the corresponding main force-bearing cavity 11, and the outer circumferential edge of the other end is provided with a flange 41, which is received in the coarse hole portion 132 and fits against the bottom of the hole of the coarse hole portion 132.

[0030] By setting an assembly tube 4 at the stepped hole, and using the flange 41 of the assembly tube 4 to fit with the bottom of the hole of the coarse hole 132, the cured frame 3 formed after the glue is injected can also fix the upper and lower side frame profiles 1 to the two assembly tubes 4 respectively, thereby enhancing the structural strength of the two side frame profiles 1 and avoiding a significant decrease in the structural strength of the middle part of the side frame profile 1 after setting the opening 13.

[0031] A further improvement includes a sealant cap 5, which cooperates with the flange 41 to fill the coarse hole portion 132. The sealant cap 5 is cured and formed by a curing adhesive and is flush with the end of the coarse hole portion 132 away from the fine hole portion 131.

[0032] By setting the sealing cap 5 to block the flange 41, a good seal is formed to prevent moisture from contacting the curing frame 3. At the same time, the sealing cap 5 is flush with the opening of the coarse hole 132, ensuring the circumferential outer edge of the frame structure, specifically the flatness of the top and bottom surfaces, which facilitates installation and fixing in the wall hole 71 of the wall 7.

[0033] A further improvement is that a reinforcing hole 42 is provided on the side wall of the assembly tube 4 away from the flange 41, and the two ends of the reinforcing hole 42 extend to the inner circumferential wall and the outer circumferential edge of the assembly tube 4, respectively.

[0034] During the injection process, some of the polyurethane heat insulation casting adhesive can fill the reinforcement hole 42 and cure to form a solid shape, thereby strengthening the connection structure between the assembly tube 4 and the curing frame 3 and preventing the assembly tube 4 from detaching from the hole 13.

[0035] A further improvement is that the wall thickness of the load-bearing corner bracket 2 is greater than that of the frame profile 1. By increasing the wall thickness of the load-bearing corner bracket 2, the structural strength of the load-bearing corner bracket 2 is ensured, thereby strengthening the structural strength at the connection between two adjacent frame profiles 1.

[0036] A further improvement is that the auxiliary cavity 12 is filled with an auxiliary heat insulation strip 6.

[0037] Before assembling the four frame profiles 1, auxiliary heat insulation strips 6 are filled into the auxiliary cavities 12 of the four frame profiles 1 respectively. Then, the four frame profiles 1 are connected end to end by four load-bearing corner brackets 2. At this time, the four auxiliary heat insulation strips 6 are connected end to end to form a heat insulation frame, which can further enhance the heat insulation performance of the frame structure. The auxiliary heat insulation strips 6 are preferably made of elastic heat insulation cotton, which can ensure that they fill the auxiliary cavity 12, reduce gaps, and enhance the overall heat insulation performance of the frame structure.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
