Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a door frame structure and a door frame installation structure. Background Technology

[0002] Chinese patent document CN220769232U discloses a technical solution entitled "Anti-Crack Coating Door Device," which includes the following technical features: an aluminum main frame, an arc-shaped notch in the anti-crack baffle, a main frame limiting groove, an anti-crack groove in the main frame coating, an anti-crack baffle, an L-shaped groove in the anti-crack baffle coating, an anti-crack groove in the baffle coating, a baffle locking arc, a W-shaped coating groove in the baffle, an L-shaped step in the baffle, a wall, straight nails in the main frame, screws in the baffle, wall coating, an anti-crack mesh, an integral main frame, and structural adhesive. While it can achieve a certain anti-crack effect through the anti-crack baffle, it also has the following shortcomings:

[0003] Because the wall coating itself is relatively thin, and the crack-resistant baffle further encroaches on it, the wall coating on the outside of the crack-resistant baffle becomes very thin. Although crack-resistant grooves for the coating are made on the outer wall of the crack-resistant baffle and crack-resistant mesh is placed on it, the thickness of the crack-resistant baffle is not thicker than the thin wall coating. Therefore, the thickness of the crack-resistant baffle is relatively thin, and the depth of the crack-resistant grooves for the coating is very shallow. As a result, the crack-resistant grooves for the coating have a weak restrictive effect on the wall coating on the outside of the baffle.

[0004] Furthermore, since the crack-prevention mesh is simply placed on the outer wall of the crack-prevention baffle, its crack-prevention effect on the wall coating on the outside of the crack-prevention baffle is limited. In addition, the wall coating at the installation location of the crack-prevention mesh is very thin, so the crack-prevention effect that the crack-prevention mesh can bring is limited.

[0005] Furthermore, due to the obstruction of the crack-resistant baffle, the wall coating on the outside of the crack-resistant baffle cannot form a reliable connection with the wall, and it is also easy for the wall coating to delaminate at the installation point of the crack-resistant baffle, which will weaken the impact resistance of the wall coating at this point.

[0006] Furthermore, the crack-resistant baffle is rotatably connected to the aluminum main frame. When the aluminum main frame is impacted, there is a possibility of relative rotational displacement between the crack-resistant baffle and the aluminum main frame. This will exert a relative displacement force on the wall paint on the outside of the crack-resistant baffle and the aluminum main frame, which may easily cause the wall paint to crack at the rotatable connection between the crack-resistant baffle and the aluminum main frame.

[0007] In summary, the anti-cracking coating device offers limited crack prevention. Furthermore, since the aluminum main frame serves as a door casing, providing mounting and support for the door leaf, each time the door is closed, it generates significant impact force on the frame, causing vibration. This vibration is directly transmitted to the crack-resistant baffle and the surrounding wall paint, further vibrating the paint. Consequently, the paint on the aluminum main frame and the wall outside the crack-resistant baffle remains prone to cracking and peeling, especially at the rotating joint between the frame and the baffle.

[0008] Therefore, it is essential to design a door frame to solve the aforementioned technical problems. Utility Model Content

[0009] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a door frame structure and a door frame installation structure. This door frame structure facilitates the creation of a door frame with high crack resistance, which can effectively reduce the probability of cracking and peeling of the wall paint at the transition between the door frame and the wall, thereby helping to form a durable and long-lasting wall decoration effect. It has the advantages of simple structure, easy construction, easy to form a highly crack-resistant wall, high reliability, and strong applicability. This door frame installation structure can provide a very strong crack resistance effect, effectively withstand the impact of closing the door, and will not cause the wall paint to crack or peel off even after long-term use, thus enabling the wall to maintain a high decoration quality for a long time. Moreover, it is very convenient to construct and can be installed quickly.

[0010] The technical solution of this utility model is implemented as follows:

[0011] A door frame structure is characterized by including a door frame body, wherein the door frame body has a groove for applying adhesive and for holding the adhesive, and the door frame body has an insert groove for inserting the end of a crack-resistant mesh or crack-resistant cloth, and the insert groove and the adhesive groove are arranged side by side.

[0012] Preferably, the front and rear surfaces of the door frame body are respectively provided with adhesive grooves, and the front and rear surfaces of the door frame body are also respectively provided with mounting grooves.

[0013] Preferably, the adhesive groove is a groove with a narrow opening and a wide interior.

[0014] Preferably, the adhesive groove is a strip-shaped groove extending along the length of the door frame body.

[0015] Preferably, the mounting slot is a strip-shaped groove extending along the length of the door frame body.

[0016] Preferably, a receiving notch is provided at the corner of the wall-joining surface of the door frame body, and the adhesive groove is provided on the opening wall of the receiving notch.

[0017] Preferably, the adhesive groove is closer to the wall surface of the door frame body than the mounting groove arranged alongside it.

[0018] Preferably, the front and rear sides of the door frame body away from the wall surface are respectively provided with arc-shaped convex edges.

[0019] Preferably, a door stop strip is integrally formed on one of the front and rear sides of the door frame body, the thickness T1 of the door frame body is 12mm, and the sum of the thickness of the door frame body and the thickness of the door stop strip T2 is 21mm.

[0020] A door frame installation structure includes a wall, characterized in that it further includes the aforementioned door frame structure, which is disposed on the side wall of the wall. The adhesive groove is filled with adhesive, which extends to the wall surface. The end of a crack-resistant mesh, crack-resistant cloth, or kraft paper is embedded in the mounting groove, and the crack-resistant mesh, crack-resistant cloth, or kraft paper covers the adhesive. The adhesive also penetrates the crack-resistant mesh or crack-resistant cloth. Wall paint is applied to the wall, and the wall paint covers the corresponding surface of the door frame structure and the crack-resistant mesh, crack-resistant cloth, or kraft paper.

[0021] The beneficial effects of this utility model are as follows: In this door frame structure, not only are there adhesive grooves for applying and securing the adhesive on the door frame body, but also inlay grooves for embedding the ends of anti-crack mesh or anti-crack fabric. Furthermore, the inlay grooves and adhesive grooves are arranged side-by-side. By creating these inlay grooves and adhesive grooves and arranging them side-by-side, it not only facilitates the manufacturing of the door frame body, but also facilitates the application of adhesive, the installation of anti-crack mesh or anti-crack fabric on the door frame body, and ensures a reliable connection between the adhesive and the door frame body, as well as between the anti-crack mesh or anti-crack fabric and the door frame body. Additionally, it facilitates the combined use of adhesive and anti-crack mesh or anti-crack fabric. This door frame structure facilitates a stable and reliable bond between the adhesive and the crack-resistant mesh or fabric. This allows the adhesive and mesh, or the adhesive and fabric, to work together to reinforce and restrict the wall paint, providing a highly stable and reliable barrier against cracking. This not only prevents paint delamination but also effectively improves the paint's impact resistance, preventing cracking at the transition between the door frame and the wall. Therefore, this door frame structure allows for the creation of highly crack-resistant door frames, significantly reducing the likelihood of paint cracking and peeling at the transition point. This results in a durable and long-lasting wall finish. Furthermore, the simple overall structure of this door frame facilitates construction and creates highly crack-resistant walls, making it highly reliable and versatile.

[0022] The adhesive used in this door frame installation structure disperses stress in the vertical, horizontal, and shear directions, forming a three-dimensional bonding network. This effectively resists the combined mechanical loads generated by the vibrations of opening and closing the door frame, reducing the risk of stress concentration at traditional mechanical fixing points. Furthermore, the adhesive provides an elastic seal between the door frame and the wall, resulting in excellent sealing, sound insulation, and heat insulation, while preventing damage to the wall paint caused by rigid connections. The adhesive, along with crack-resistant mesh, cloth, or kraft paper, provides a dual crack-resistant effect on the wall paint. The adhesive ensures the stability of the door frame structure, crack-resistant mesh, cloth, or kraft paper, and the corresponding wall paint installation. This door frame installation structure provides strong crack resistance, effectively withstanding the impact of closing the door and preventing paint cracking or peeling even after prolonged use, thus maintaining a high-quality finish on the wall for a long time. Moreover, it is very convenient to install, allowing for quick completion. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the door frame structure in this utility model.

[0024] Figure 2 This is one of the structural diagrams of the door frame installation structure in this utility model.

[0025] Figure 3 This is the second structural diagram of the door frame installation structure in this utility model.

[0026] Figure 4 This is the third structural diagram of the door frame installation structure in this utility model. Detailed Implementation Example

[0027] like Figure 1 As shown, the door frame structure of this utility model includes a door frame body 1, wherein the door frame body 1 is provided with a glue-holding groove 11 for applying adhesive and for holding the adhesive, and the door frame body 1 is provided with an inlay groove 12 for inserting the end of the anti-crack mesh or anti-crack cloth, and the inlay groove 12 and the glue-holding groove 11 are arranged side by side.

[0028] In this door frame structure, not only is there a groove 11 for applying adhesive and holding the adhesive on the door frame body 1, but also an inlay groove 12 for inserting the end of the anti-crack mesh or anti-crack cloth on the door frame body 1, and the inlay groove 12 and the adhesive groove 11 are arranged side by side. By opening the above-mentioned inlay groove 12 and adhesive groove 11 and arranging them side by side, it is not only convenient to manufacture the door frame body 1, but also convenient to apply adhesive to the door frame body 1, install anti-crack mesh or anti-crack cloth, and make it easy to achieve a reliable connection between the adhesive and the door frame body 1, and between the anti-crack mesh or anti-crack cloth and the door frame body 1, and also make it easy to use the adhesive and the anti-crack mesh or anti-crack cloth together.

[0029] This door frame structure facilitates a stable and reliable fit between the adhesive and the crack-resistant mesh or cloth, allowing the adhesive and the crack-resistant mesh, or the adhesive and the crack-resistant cloth, to work together to reinforce and limit the wall coating. This provides a very stable and reliable constraint and crack prevention effect on the wall coating, not only preventing paint delamination but also effectively improving the impact resistance of the wall coating. It effectively prevents cracking of the wall coating at the transition between the door frame body 1 and the wall.

[0030] Therefore, this door frame structure facilitates the creation of door frames with high crack resistance, which can effectively reduce the probability of cracking and peeling of wall paint at the transition between the door frame and the wall, thus creating a durable and long-lasting wall decoration effect. In addition, the overall structure of this door frame is simple, easy to construct, and conducive to the formation of highly crack-resistant walls, thus possessing very high reliability and applicability.

[0031] In actual use, first install the door frame body 1 on the side wall corresponding to the door opening in the wall; then fill the adhesive groove 11 with adhesive (for example, use structural adhesive, epoxy resin adhesive or polyurethane adhesive, etc., which have strong adhesive effect as adhesive), and extend the adhesive to the wall; before the adhesive dries, insert the end of the crack-resistant mesh or crack-resistant cloth into the insertion groove 12, and cover the adhesive on the wall with the crack-resistant mesh or crack-resistant cloth. At this time, the undried adhesive will penetrate through the crack-resistant mesh or crack-resistant cloth (because both the crack-resistant mesh and crack-resistant cloth have holes, this can meet the penetration requirements) to the outer surface of the crack-resistant mesh or crack-resistant cloth; finally, apply the wall paint layer. This design allows for the application of a sufficiently thick layer of wall paint at the transition between the door frame body 1 and the wall. The adhesive, along with crack-resistant mesh or fabric, works together to restrict the paint application, providing a stable and reliable barrier and resulting in a highly stable and reliable crack-resistant effect. Furthermore, this design prevents delamination, giving the wall paint strong impact resistance and effectively preventing cracking and peeling at the junction of the door frame body 1 and the wall. The crack-resistant effect of this door frame structure is extremely strong; it can better withstand the impact of closing the door, significantly reducing the likelihood of cracking and peeling of the wall paint at the transition between the door frame and the wall, thus creating a durable and long-lasting wall decoration effect.

[0032] In practical applications, kraft paper can be used instead of anti-crack mesh or anti-crack cloth. Although kraft paper does not allow for easy penetration of adhesive, it has excellent anti-crack properties and a sufficient thickness of wall paint can still be maintained on the outside of the kraft paper. Therefore, using kraft paper can still produce a very strong anti-crack performance. Compared with the anti-crack coating door device in the background technology, it still has more stable and reliable impact resistance and anti-crack performance. This can still effectively reduce the probability of cracking and peeling of the wall paint at the transition between the door frame and the wall, thus forming a long-lasting and durable wall decoration effect.

[0033] like Figure 1 As shown, adhesive grooves 11 are respectively provided on the front and rear surfaces of the door frame body 1, and mounting grooves 12 are also respectively provided on the front and rear surfaces of the door frame body 1. In this way, adhesive can be applied and anti-crack mesh or anti-crack cloth can be installed on both the front and rear of the door frame body 1, which can help to play a two-way restrictive and reinforcing role, thereby helping to further improve the reliability and applicability of the door frame structure.

[0034] like Figure 1As shown, the adhesive groove 11 has a narrow opening and a wide interior. This not only gives the adhesive groove 11 a relatively simple structure, but also facilitates the proper positioning of the dried adhesive, thereby enabling the adhesive to exert a more stable and reliable strengthening and restraining effect, and further improving the reliability and applicability of the door frame structure.

[0035] like Figure 1 As shown, the adhesive groove 11 is a C-shaped groove, which not only facilitates the control of manufacturing costs, but also facilitates the application and flow of adhesive, and provides a very stable and reliable locking and positioning effect for the adhesive, thereby effectively improving the bonding strength between the adhesive and the door frame body 1.

[0036] In actual manufacturing, the adhesive groove 11 can be made into a groove with a narrow opening and a wide interior, or it can be made into a groove with the same width inside and outside or a groove with a slightly larger opening. The adhesive groove 11 is located on the front or rear wall of the door frame body 1. In this way, the adhesive applied to the outside of the adhesive groove 11 is arranged horizontally, so that the adhesive inside and outside the adhesive groove 11 is in different directions. This can effectively limit the adhesive outside the adhesive groove 11 by using the adhesive inside the adhesive groove 11. In addition, the adhesive itself has the effect of bonding and fixing, thus well meeting the needs of actual use.

[0037] like Figure 1 As shown, the adhesive groove 11 is a strip-shaped groove extending along the length of the door frame body 1. This facilitates the application of more comprehensive adhesive between the door frame structure and the wall, thereby achieving a more comprehensive, stable, and reliable anti-cracking effect.

[0038] like Figure 1 As shown, the mounting groove 12 is a strip-shaped groove extending along the length of the door frame body 1. This facilitates a more comprehensive and effective positioning of the ends of the anti-crack mesh or anti-crack cloth, thereby enabling the anti-crack mesh or anti-crack cloth to exert a more comprehensive, stable, and reliable anti-crack effect.

[0039] like Figure 1 As shown, a receiving notch 14 is provided at the corner of the wall-connecting surface 13 of the door frame body 1, and the adhesive groove 11 is formed on the opening wall of the receiving notch 14. Such a receiving notch 14 can facilitate the application of more adhesive between the door frame body 1 and the wall, thereby enhancing the connection strength between the door frame body 1 and the wall, and thus enabling a more stable and reliable anti-cracking effect.

[0040] like Figure 1As shown, the adhesive groove 11 is closer to the wall surface 13 of the door frame body 1 than the mounting groove 12 arranged alongside it. This not only allows for the sequential placement of adhesive, crack-resistant mesh, or crack-resistant cloth, but also facilitates a reliable crack-resistant effect, thereby improving the convenience and quality of construction.

[0041] like Figure 1 As shown, the front and rear sides of the door frame body 1, away from the wall surface 13, are respectively provided with arc-shaped finishing edges 15 on the top surface. The provision of such finishing edges 15 not only improves the convenience of finishing the wall paint, but also enhances the quality of the finishing.

[0042] like Figures 1 to 4 As shown, a door stop strip 17 is integrally formed on one of the front and rear sides of the door frame body 1, which is connected to the door surface 16. The thickness T1 of the door frame body 1 is 12mm, and the sum of the thickness of the door frame body 1 and the thickness of the door stop strip 17, T2, is 21mm. This allows for the installation of one or two standard thickness (9.5mm) gypsum boards 100 corresponding to the front and rear of the door frame structure, and leaves a suitable plastering space on the outer side of the gypsum board 100. This not only facilitates the application of wall paint on the gypsum board 100 but also ensures that the wall paint has a suitable thickness. Such a door frame structure can easily accommodate a wider range of installation needs, thereby further improving the applicability of the door frame structure. Example

[0043] like Figures 2 to 4 As shown, a door frame installation structure includes a wall 10 and a door frame structure 20 as described in Embodiment 1. The door frame structure 20 is disposed on the side wall 101 of the wall 10. The adhesive groove 11 is filled with adhesive 30, which extends to the wall 102 of the wall 10. The end of the anti-crack mesh 40, anti-crack cloth, or kraft paper is embedded in the mounting groove 12, and the anti-crack mesh 40, anti-crack cloth, or kraft paper covers the adhesive 30. The adhesive 30 also penetrates the anti-crack mesh 40 or anti-crack cloth. The wall 102 is coated with wall paint 50, which covers the corresponding surface of the door frame structure 20 and the anti-crack mesh 40, anti-crack cloth, or kraft paper.

[0044] The adhesive 30, installed on this door frame installation structure, disperses stress in the vertical, horizontal, and shear directions, forming a three-dimensional bonding network. This effectively resists the combined mechanical loads generated by the vibration of opening and closing the door frame, reducing the risk of stress concentration at traditional mechanical fixing points. Furthermore, the adhesive 30 provides an elastic seal between the door frame body 1 and the wall 10, resulting in excellent sealing, sound insulation, and heat insulation for the door, while also preventing damage to the wall paint 50 caused by rigid connections. The adhesive 30, along with the crack-resistant mesh 40, crack-resistant cloth, or kraft paper, provides a dual crack-resistant effect on the wall paint 50. The adhesive 30 ensures the stable installation of the door frame structure 20, the crack-resistant mesh 40, crack-resistant cloth, or kraft paper, and the corresponding wall paint 50. This door frame installation structure provides a strong crack-resistant effect, effectively withstanding the impact of closing the door and preventing cracking or peeling of the wall paint over long-term use, thus maintaining a high-quality finish on the wall surface for an extended period. Moreover, it is very convenient to construct and can facilitate quick installation.

[0045] like Figures 2 to 4 As shown, when installing the anti-crack mesh 40, anti-crack cloth, or kraft paper, a limiting strip 60 is required. The specific installation process is as follows: First, overlap the end of the anti-crack mesh 40, anti-crack cloth, or kraft paper onto the groove of the mounting slot 12; then press the limiting strip 60 onto the anti-crack mesh 40, anti-crack cloth, or kraft paper on the groove of the mounting slot 12; then press the limiting strip 60 firmly into the inside of the mounting slot 12. At this time, the limiting strip 60 pushes the end of the anti-crack mesh 40, anti-crack cloth, or kraft paper into the mounting slot 12, and the side wall of the limiting strip 60 and the groove wall of the mounting slot 12 together clamp the end of the anti-crack mesh 40, anti-crack cloth, or kraft paper, so as to stably position the end of the anti-crack mesh 40, anti-crack cloth, or kraft paper in the mounting slot 12. This allows for quick and stable installation and positioning of the anti-crack mesh 40, anti-crack cloth, or kraft paper. This not only improves construction efficiency but also ensures that the installation and positioning of the anti-crack mesh 40, anti-crack cloth, or kraft paper are very stable and reliable, thus guaranteeing that the door frame installation structure has very high reliability and applicability.

[0046] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
