Description

Technical Field

[0001] This utility model belongs to the field of door frame assembly technology, and more specifically, it relates to a low-energy door frame assembly structure. Background Technology

[0002] The main entrance doors of residential buildings often have large opening areas. Existing unit doors are typically made of steel or thermally broken aluminum alloy profiles. To ensure overall structural strength, the door panels are often joined by welding or metal screws. However, due to the poor thermal insulation of thermally broken aluminum alloy profiles, the construction market is now promoting the use of polyurethane pultruded profiles to replace steel or thermally broken aluminum alloy profiles in order to meet the requirements of low-energy building standards. In existing door panel frame structures, polyurethane pultruded profile splicing corner brackets are mainly used in windows, cut at 45° angles and connected. Windows generally have small opening areas, and due to their light weight, these defects are not very noticeable. However, when used in large-sized unit doors, unevenness and warping problems appear at the profile splicing points, leading to cracks during use and water seepage into the corner cavities. This affects the overall aesthetics of the doors and windows, causing leakage and other quality problems, thus impacting thermal insulation performance. Therefore, a low-energy door panel frame structure is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a low-energy door frame assembly structure. By connecting the light switch and the horizontal frame with frame corner brackets and injecting glue at the connection points, it solves the problems mentioned in the background art, such as unevenness and warping at the profile splicing points when polyurethane pultruded profiles are used in large-size unit doors. This leads to cracks at the splicing points during use, water seepage in the corner cavities, affecting the overall aesthetics of the doors and windows and causing quality problems such as leakage, thereby affecting the thermal insulation performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-energy door frame assembly structure, comprising a light switch, a horizontal frame, frame corner brackets, and frame clamping plates. The frame corner bracket includes an outer frame and reinforcing ribs. Two first through holes are provided on the outer side of the frame corner bracket, and anti-slip anti-reverse bolts are provided inside the two first through holes. Spring washers are provided between the anti-slip anti-reverse bolts and the frame corner bracket. Two first threaded holes are provided on the outer side of the frame clamping plates. A through glue groove is provided on the side of the frame corner bracket near the light switch. Two second threaded holes are provided on both the upper and lower sides of the frame corner bracket. Frame glue is provided inside the through glue groove. Glue injection ports are provided on both the upper and lower sides of the horizontal frame. Second through slots are also provided on both the upper and lower sides of the horizontal frame. Eccentric locking screws are provided inside the two second through slots. The lower end of the eccentric locking screw is threaded to the inner side of the second threaded hole.

[0005] As a preferred embodiment of this utility model, the frame corner code is located on the lower outer side of the optical drive.

[0006] As a preferred embodiment of this utility model, the frame clamp is located on the lower inner side of the light starter.

[0007] As a preferred embodiment of this utility model, the positions of the two first threaded holes correspond to the positions of the two first through holes, respectively.

[0008] As a preferred technical solution of this utility model, one end of the anti-slip anti-reverse bolt extends through the outer side of the light switch to the inner side and is threadedly connected to the inner side of the first threaded hole.

[0009] As a preferred embodiment of this utility model, the position of the glue injection port corresponds to the position of the through glue tank.

[0010] As a preferred embodiment of this utility model, the positions of the two second through slots correspond to the positions of the two second threaded holes, respectively.

[0011] This utility model provides a low-energy door frame structure, which has the following advantages:

[0012] This low-energy door frame structure connects the light switch and the horizontal frame through frame corner brackets and injects glue at the joints. This solves the problems of unevenness and warping at the joints of the profiles that occur when used on large-sized unit doors. These problems lead to cracks at the joints and water seepage in the corner cavities during use, affecting the overall appearance of the doors and windows and causing quality issues such as leakage, which in turn affects the thermal insulation performance.

[0013] 2. This low-energy door frame structure features a closed-end corner bracket, increasing strength and overall stability. The corner bracket, guided by an inclined plane, fully fills the cavity of the horizontal frame, transforming the stress on the profile from a single point to a force on four surfaces, resulting in more even stress distribution and preventing stress concentration that could cause cracking. The corner bracket and the light switch are fixed with a clamping plate structure, increasing the bolt bearing surface and improving the load-bearing capacity and torsional force of the corner bracket.

[0014] 4. The screw holes of the frame corner brackets adopt an eccentric design, which improves the adjustability and connection tightness of the corner brackets.

[0015] 5. The cross-section has a pre-reserved glue groove, which can be injected with polyurethane corner glue to seal and connect the parts.

[0016] 6. The corner bracket cavity of the horizontal frame is centrally located, with reserved cavities on both sides to cut off heat transfer. This also further improves the strength of the door leaf at the corner joint, ensuring that the corner joint is not easy to crack or fall off when subjected to external pressure, thereby further improving the structural stability of the entire door leaf.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a low-energy door frame structure, including a light switch 1, a horizontal frame 2, frame corner brackets 3, and frame clamping plates 4. The frame corner bracket 3 includes an outer frame 31 and reinforcing ribs 32. Two first through holes 5 are opened on the outer side of the frame corner bracket 3, and anti-slip anti-reverse bolts 6 are provided inside the two first through holes 5. Spring washers 7 are provided between the anti-slip anti-reverse bolts 6 and the frame corner bracket 3. Two first threaded holes 8 are opened on the outer side of the frame clamping plate 4. A through glue groove 9 is provided on the side of the frame corner bracket 3 near the light switch 1. Two second threaded holes 10 are opened on the upper and lower sides of the frame corner bracket 3. Frame glue 11 is provided inside the through glue groove 9. Injection holes 11 are opened on the upper and lower sides of the horizontal frame 2. The glue inlet 12 and the upper and lower sides of the horizontal frame 2 are also provided with second through grooves 13. The two second through grooves 13 are provided with eccentric locking screws 14. The lower end of the eccentric locking screws 14 is connected to the inner thread of the second threaded hole 10. The frame bracket 3 is located on the lower outer side of the optical starter 1. The frame clamp 4 is located on the lower inner side of the optical starter 1. The positions of the two first threaded holes 8 correspond to the positions of the two first through holes 5 respectively. One end of the anti-slip anti-reverse bolt 6 passes through the outer side of the optical starter 1 and extends to the inner side and is connected to the inner thread of the first threaded hole 8. The position of the glue inlet 12 corresponds to the position of the through glue groove 9. The positions of the two second through grooves 13 correspond to the positions of the two second threaded holes 10 respectively.

[0026] The door panel's light switch 1 and horizontal frame 2 are cut and drilled to the required dimensions. Anti-slip anti-reverse bolts 6 pass through the first through hole 5 on the frame bracket 3 and the outside of the light switch 1, and are threadedly connected to the first threaded hole 8 on the frame clamp 4, thus fixing the frame clamp 4 to the light switch 1. The frame clamp 4 is embedded in the groove on the inner side of the light switch 1, restricting the frame clamp 4 from rotating freely and ensuring structural stability. Then, the horizontal frame 2 is connected to the frame bracket 3. An eccentric locking screw 14 is screwed into the second through slot 13 on the horizontal frame 2 using a special tool. The lower end of the eccentric locking screw 14 is threaded into the second threaded hole 10 on the frame bracket 3. Due to the eccentric effect, the horizontal frame 2 profile is pressed against the light switch 1 to achieve a tight connection between the horizontal frame 2 and the light switch 1 profile surfaces. After the light switch 1 and horizontal frame 2 are connected, the horizontal frame... One of the injection ports 12 on the frame 2 is injected with two-component polyurethane corner adhesive. The two-component polyurethane corner adhesive flows into the through-glue groove 9 on the frame corner bracket 3 to form frame adhesive 11. During the injection process, if adhesive flows out from the other injection port 12, the injection is complete. After the adhesive cures, it can further improve the required strength of the corner bracket. At the same time, the gap at the frame corner bracket is completely filled by the frame adhesive 11 through the through-glue groove 9, which can further improve the air tightness and water tightness. Through the above process, the problems of unevenness and warping at the splicing of profiles that occur when used on large-size unit doors are solved. This leads to cracks at the splicing points during use, water seepage in the corner cavities, affecting the overall aesthetics of the doors and windows and causing quality problems such as leakage, thus affecting the thermal insulation performance.

[0027] The specific usage and function of this embodiment: In this embodiment, the door panel's light switch 1 and horizontal frame 2 are cut and drilled according to the required dimensions. Anti-slip anti-reverse bolts 6 pass through the first through hole 5 on the frame bracket 3 and the outside of the light switch 1, and are threadedly connected to the first threaded hole 8 on the frame clamp 4, thus completing the fixation of the frame clamp 4 to the light switch 1. The frame clamp 4 is embedded in the groove on the inner side of the light switch 1, restricting the frame clamp 4 from rotating freely and ensuring structural stability. Then, the horizontal frame 2 is connected to the frame bracket 3. An eccentric locking screw 14 is screwed into the second through slot 13 on the horizontal frame 2 using a special tool. The lower end of the eccentric locking screw 14 is connected to the second threaded hole 1 on the frame bracket 3. 0-threaded connection. Due to eccentricity, the cross frame 2 profile is squeezed towards the light-emitting diode 1 to achieve a tight connection between the cross frame 2 and the light-emitting diode 1 profile. After the connection between the light-emitting diode 1 and the cross frame 2 is completed, two-component polyurethane corner glue is injected through one of the glue injection ports 12 on the cross frame 2. The two-component polyurethane corner glue flows into the through glue groove 9 on the corner bracket 3 to form the frame glue 11. When glue is found to flow out of the other glue injection port 12 during the glue injection process, the glue injection is completed. After the glue cures, the required strength of the corner bracket can be further improved. At the same time, the gap at the corner bracket is completely filled by the frame glue 11 through the through glue groove 9, which can further improve the air tightness and water tightness.
