Description

Technical Field

[0001] This disclosure relates to the field of building profile technology, and more specifically, to a nail-free leveling keel component and its installation method. Background Technology

[0002] Keel is a building material used to support shapes and fix structures. There are many types of keels, which can be divided into ceiling keels, wall keels, floor keels, and hanging keels according to their use. With the development of material technology, traditional pipe-type keel products have been gradually replaced by keel assemblies with multiple components due to the difficulty of installation and the need for leveling.

[0003] However, practical applications have revealed that while some keel assemblies composed of multiple parts represent an improvement over traditional keel products and effectively reduce installation difficulty, they still inevitably require multiple screws to complete the installation. This means that the majority of installation time is spent on tightening the screws. Therefore, reducing or even eliminating the time spent tightening screws during the installation of keel assemblies has become a key technical issue for further improving installation efficiency. Summary of the Invention

[0004] The purpose of this disclosure is to provide a nail-free leveling keel component and its installation method, so as to overcome the technical problem that some existing keel components require a lot of time to nail the components of the leveling keel component during installation.

[0005] According to one embodiment of this disclosure, a nail-free leveling keel assembly is provided, including a fastener and a keel;

[0006] The fastener has a first groove extending in a straight line, and the bottom wall of the first groove is provided with opposing first groove sidewalls and second groove sidewalls. At least one vertical and bendable fastening strip is connected to each of the first groove sidewalls and the second groove sidewalls.

[0007] The keel has a second groove extending in a straight line. The bottom wall of the second groove is provided with a third groove sidewall and a fourth groove sidewall. The bottom wall of the second groove is provided with adjustment holes for the fixing strip to pass through. There are multiple adjustment holes, which are divided into two rows. The two rows of adjustment holes are arranged opposite to each other on the bottom wall of the second groove near the third groove sidewall and the fourth groove sidewall. Each row of adjustment holes is arranged sequentially along the straight extension direction of the second groove, and each row of adjustment holes includes at least one adjustment hole and limiting retaining edges on the outer side of the third groove sidewall and the fourth groove sidewall respectively. The limiting retaining edges are parallel to the straight extension direction of the second groove.

[0008] When the keel is connected to the fastener, the fixing strips on the first and second groove sidewalls pass through the adjustment hole along the inner side of the third and fourth groove sidewalls and bend continuously towards the outer side of the second groove sidewall to form a limiting edge that is tightly fastened to the limiting card edge.

[0009] In one embodiment, the limiting edge is a first folded edge formed by folding the top of the groove sidewall of the second groove outward. The first folded edge is perpendicular to the groove sidewall of the second groove or inclined in a direction away from the bottom wall of the groove.

[0010] In one embodiment, the limiting edge includes a second folded edge formed by bending along the outer edge of the connection between the sidewall and bottom wall of the second groove, and a third folded edge formed by bending along the edge of the limiting edge, the third folded edge being close to the first folded edge.

[0011] In one embodiment, the fastener is an aluminum fastener or a steel fastener; the keel is an aluminum keel or a steel keel.

[0012] In one embodiment, the tops of the first groove sidewall and the second groove sidewall are flush, and the shape of the fixing strip is rectangular; when the keel is connected to the fixing member, the tops of the first groove sidewall and the second groove sidewall abut against the bottom wall of the second groove.

[0013] In one embodiment, the first groove sidewall and the second groove sidewall are parallel to the connected fixing strip and have the same thickness.

[0014] In one embodiment, the first groove and the fixing strip are integrally formed.

[0015] In one embodiment, the outer side of the bottom wall of the first groove is a plane.

[0016] In one embodiment, the bottom wall of the first groove is provided with a through hole penetrating the bottom of the groove.

[0017] According to another embodiment of this disclosure, an installation method for the above-mentioned nail-free leveling keel assembly is provided, comprising:

[0018] Step 1: Secure the fastener vertically to the wall;

[0019] Step 2: Align the groove of the second recess of the keel with the fastener, let the fixing strip on the fastener pass through the adjustment hole on the keel, press the keel tight, and fold the fixing strip that extends out of the adjustment hole outward continuously into the limiting clips on both sides of the keel to complete the fixed connection between the keel and the fastener.

[0020] The beneficial effects of the nail-free leveling keel assembly provided in this disclosure are at least as follows: by aligning the groove of the first groove where the fastener is located with the groove of the second groove where the keel is located, the first groove sidewall and the second groove sidewall of the first groove are inserted into the second groove, thereby forming a groove space between the keel and the fastener, allowing the pipeline to share the space with the keel and reducing space occupation; in addition, the fixing strip on the fastener is inserted into the adjustment hole on the keel, and after continuous bending, it forms a limiting edge that engages with the limiting edge, avoiding the use of fasteners for fixing during the assembly and installation of the keel and the fastener, making the installation of the keel more convenient and efficient.

[0031] Please see Figure 1-3 This embodiment provides a nail-free leveling keel assembly, including a fastener 1 and a keel 2. The fastener 1 has a first groove 11 extending in a straight line. The bottom wall 12 of the first groove has opposing first groove sidewalls 13 and second groove sidewalls 14. At least one vertical and bendable fixing strip 15 is connected to each of the first groove sidewalls 13 and second groove sidewalls 14. The keel 2 has a second groove 21 extending in a straight line. The bottom wall 22 of the second groove has a third groove sidewall 23 and a fourth groove sidewall 24. The bottom wall 22 of the second groove has adjustment holes 25 for the fixing strips 15 to pass through. There are multiple adjustment holes 25 arranged in two rows, with the two rows of adjustment holes 25 positioned opposite each other near the third groove sidewall 23 and the fourth groove sidewall 24. On the bottom wall 22 of the second groove of 4, each row of adjustment holes 25 is arranged sequentially along the straight extension direction of the second groove 21, and each row of adjustment holes 25 includes at least one adjustment hole 25, and limiting edges 26 on the outer side of the third groove side wall 23 and the fourth groove side wall 24 respectively, the limiting edges 26 being parallel to the straight extension direction of the second groove 21; when the keel 2 is connected to the fixing member 1, the fixing strips 15 on the first groove side wall 13 and the second groove side wall 14 pass through the adjustment holes 25 along the inner side of the third groove side wall 23 and the fourth groove side wall 24, and continuously bend towards the outer side of the groove side wall 22 of the second groove, forming a limiting edge 17 tightly fastened to the limiting edge 26.

[0032] Specifically, such as Figure 2 As shown, the fastener 1 is constructed as a groove-shaped component with a structure similar to the first groove 11. The first groove 11 extends along the straight line L and includes a bottom wall, a first side wall 13, and a second side wall 14. The first side wall 13 and the second side wall 14 are disposed opposite to each other on the bottom wall 12 of the first groove on both sides of the straight line L. A fixing strip 15 is connected to each of the first side wall 13 and the second side wall 14. In this embodiment, the fixing strip 15 is preferably rectangular in shape.

[0033] Specifically, such as Figure 3 As shown, the keel 2 is constructed as a groove-shaped component with a structure similar to the second groove 21. The second groove 21 also extends along the straight line L. The second groove 21 includes a bottom wall, a third side wall 23, and a fourth side wall 24. The third side wall 23 and the fourth side wall 24 are respectively arranged on the bottom wall 22 of the second groove on both sides of the straight line L. A row of adjustment holes 25 is provided on the side of the bottom wall 22 of the second groove near the third side wall 23, and another row of adjustment holes 25 is provided on the side of the bottom wall 22 of the second groove near the fourth side wall 24. The two rows of adjustment holes 25 are parallel to each other, and each row contains 5 adjustment holes 25 arranged alternately (the actual number of adjustment holes 25 may not be this number).

[0034] When installing fastener 1 and keel 2, as follows Figure 1 As shown, align the adjusting hole 25 on the bottom wall 22 of the second groove of the keel 2 with the fixing strip 15 on the side wall 13 and side wall 14 of the first groove of the fixing member 1. Then, pass the fixing strip 15 through the adjusting hole 25 along the outer wall of the side wall 13 and side wall 14 of the first groove, so that the side wall 13 and side wall 14 of the first groove are inserted into the second groove 21. The fixing strip 15 extending out of the adjusting hole 25 is continuously bent towards the nearest limiting edge 26 to form a buckle structure that engages with the limiting edge 26. Figure 1 The limiting edge 17 is fastened to the limiting edge 26, thereby fixing the keel 2 to the fastener 1.

[0035] According to the nail-free leveling keel assembly provided in this embodiment, the slot of the first groove 11 of the fixing member 1 is aligned with the slot of the second groove 21 of the keel 2. The first groove sidewall 13 and the second groove sidewall 14 of the first groove 11 are inserted into the second groove 21, thereby forming a groove space between the keel 2 and the fixing member 1. This allows the pipeline to share space with the keel 2, reducing space occupation. In addition, the fixing strip 15 on the fixing member 1 is inserted into the adjustment hole 25 on the keel 2 and continuously bent to form a limiting edge 17 that engages with the limiting edge 26. This avoids the need to use fasteners for fixing during the assembly and installation of the keel 2 and the fixing member 1, making the installation of the keel 2 more convenient and efficient.

[0036] In some embodiments, combined with Figure 3 As shown, the limiting edge 26 is a first folded edge formed by folding the top of the third groove sidewall 23 and the fourth groove sidewall 24 of the second groove 21 outward. The first folded edge is perpendicular to the third groove sidewall 23 and the fourth groove sidewall 24 of the second groove 21, or inclined in the direction away from the bottom wall 22 of the groove.

[0037] Specifically, the first folded edge formed by folding the third groove sidewall 23 and the fourth groove sidewall 24 outwards allows the first folded edge to be integrally formed with the corresponding third groove sidewall 23 and fourth groove sidewall 24, thereby improving the processing efficiency of the keel 2 structure. Of course, in practical applications, the limiting edge 26 can also be connected to other positions on the outside of the third groove sidewall 23 and the fourth groove sidewall 24 by welding or other methods, and this embodiment does not limit this.

[0038] In some embodiments, combined with Figure 1 As shown, when the fastener 1 is connected to the keel 2, the limiting edge 17 formed by the continuous bending of the fastening strip 15 includes a second folded edge 171 formed by bending along the outer edge of the connection between the groove side wall and the groove bottom wall of the second groove 21, and a third folded edge 172 formed by bending along the edge of the limiting edge 26. The third folded edge 172 is close to the first folded edge.

[0039] Specifically, the connection between the sidewall and bottomwall of the second groove 21 includes the connection between the bottomwall 22 and the sidewall 23 of the second groove, and the connection between the bottomwall 22 and the sidewall 24 of the second groove. By bending the fixing strip 15 at the outer edge of the connection and then bending it along the edge of the limiting edge 26, a limiting edge 17 is formed. The limiting edge 17 and the first folded edge where the limiting edge 26 is located are interlocked, so that the keel 2 and the fixing member 1 are fixedly connected together, realizing the nail-free connection between the keel 2 and the fixing member 1.

[0040] In addition, in order to facilitate the continuous bending of the fixing strip 15 while maintaining the rigidity of the keel 2, in some embodiments, the fixing member 1 can preferably be an aluminum fixing member 1 or a steel fixing member 1; in addition, the keel 2 can preferably be an aluminum keel 2 or a steel keel 2.

[0041] In some embodiments, combined with Figure 1 and 2 As shown, the tops of the first groove sidewall 13 and the second groove sidewall 14 are flush, and the shape of the fixing strip 15 is rectangular; when the keel 2 is connected to the fixing member 1, the tops of the first groove sidewall 13 and the second groove sidewall 14 abut against the bottom wall 22 of the second groove.

[0042] Specifically, the tops of the first groove sidewall 13 and the second groove sidewall 14 are flush, so that when the keel 2 is connected to the fixing member 1, the tops of the first groove sidewall 13 and the second groove sidewall 14 abut against the bottom wall 21 of the second groove, thereby ensuring the flatness of the keel 2 installation. In addition, the rectangular shape of the fixing strip 15 can reduce the processing difficulty of the fixing member 1. At the same time, when the fixing strip 15 has a uniform width, the external force applied when it is continuously bent will not result in different positions requiring different forces.

[0043] In some embodiments, such as Figure 2As shown, the first groove sidewall 13 and the second groove sidewall 14 are parallel to the connected fixing strip 15 and have the same thickness.

[0044] Specifically, the first groove sidewall 13 and the second groove sidewall 14 are on the same plane as the fixing strip 15 to which they are connected. The thickness of the first groove sidewall 13 and the second groove sidewall 14 can be greater than the thickness of the fixing strip 15, or the thickness of the first groove sidewall 13 and the second groove sidewall 14 can be the same as the thickness of the fixing strip 15. In practical applications, it is preferable that the thickness of the first groove sidewall 13 and the second groove sidewall 14 is the same as the thickness of the fixing strip 15, so that plates of the same thickness can be used for processing, thereby reducing the processing difficulty of the fastener 1.

[0045] In some embodiments, such as Figure 2 As shown, the first groove 11 and the fixing strip 15 are integrally formed.

[0046] Specifically, the sheet metal can be processed by stamping to obtain the structure of the fastener 1 where the first groove 11 and the fixing strip 15 are located. This not only makes the connection between the fixing strip 15 and the first groove sidewall 13 and the second groove sidewall 14 more secure, but also further improves the processing efficiency of the fastener 1.

[0047] In one embodiment, such as Figure 2 As shown, the outer side of the bottom wall 12 of the first groove is a plane.

[0048] Specifically, the fastener 1 is used for fixed connection with the wall. In order to ensure the flatness of the keel 2, the outer side of the bottom wall 12 of the first groove is flat, so that when installing the fastener 1, the fastener 1 can be quickly and flatly fixed to the wall.

[0049] Furthermore, fasteners can be used to secure the fastener 1 to the wall, or structural adhesive can be used to glue the fastener 1 to the wall. The connection method between the fastener 1 and the wall can be selected according to the specific scenario, and this embodiment does not limit this.

[0050] If fastener 1 is connected to the wall using fasteners, preferably, such as Figure 2 As shown, the bottom wall 12 of the first groove has a through hole 16 that penetrates the bottom of the groove. In this way, when the fastener 1 is against the wall, the fastener can be directly aligned with the through hole 16 to fix the fastener 1 to the wall.

[0051] In practical applications, the nail-free leveling keel assembly provided in the above embodiments is used for vertical installation on the wall to fix the wall panel on the keel 2.

[0052] Based on the above embodiments, please refer to Figure 4The following embodiment also provides an installation method for the above-mentioned nail-free leveling keel assembly, including:

[0053] Step 1: Vertically fix the fastener 1 to the wall 3;

[0054] Step 2: Align the groove of the second groove 21 of the keel 2 with the fixing member 1, let the fixing strip 15 on the fixing member 1 pass through the adjustment hole 25 on the keel 2, press the keel 2 tight, and fold the fixing strip 15 that extends out of the adjustment hole 25 outward continuously into the limiting clip edge 26 on both sides of the keel 2 to complete the fixed connection between the keel 2 and the fixing member 1.

[0055] Specifically, the aforementioned nail-free leveling keel components are generally used for vertical installation on walls to install and fix wall panels 8.

[0056] For example, such as Figure 4 As shown, the steps for fixing the wall panel using the nail-free leveling keel assembly are as follows: fix the fastener 1 vertically to the wall 3; align the groove of the second groove 21 of the keel 2 with the fastener 1, let the fixing strip 15 on the fastener 1 pass through the adjustment hole 25 on the keel 2, press the keel 2, and fold the fixing strip 15 extending out of the adjustment hole 25 continuously outward into the limiting clip edge 26 on both sides of the keel 2 to complete the fixed connection between the keel 2 and the fastener 1; fix a layer of sound-absorbing pad 5 on the surface of the keel 2; set the I-beam 6 on the sound-absorbing pad 5 and fix the I-beam 6 to the keel 2, and then install the wall panel 8 on the keel 2 through the I-beam 6.

[0057] Specifically, the fastener 1 can be fixed to the wall 3 using a first fastener 4, and the I-beam 6 can be fixed to the keel 2 using a second fastener 7. In this embodiment, the first fastener 4 is preferably an expansion tube and a screw, and the second fastener 7 is preferably a screw.

[0058] According to the technical solution provided in this disclosure, in the process of vertically fixing the nail-free leveling keel assembly to the wall, it is only necessary to pass the fixing strip 15 on the fixing member 1 through the adjustment hole 25 on the keel 2 and bend the fixing strip 15 to fold into the limiting clip edge 26, so that the keel 2 and the fixing member 1 can be quickly connected and fixed to each other without the need for screws or other fixing members 1, which is very convenient.

[0059] The above are merely preferred embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
