Description

Technical Field

[0001] A wall embedded mounting seat and a special mounting key relate to the field of building materials, and in particular to a embedded mounting seat made of building cementitious material for hollow walls and a special key for its installation. Background Art

[0002] Currently, interior and exterior partition walls in both concrete-frame and steel-structured buildings worldwide are typically hollow walls or solid lightweight walls. While these walls offer numerous advantages, such as energy efficiency, thermal insulation, and light weight, they also have drawbacks. Due to the thinness of hollow walls and the loose internal material structure of solid lightweight walls, it's difficult to securely attach fasteners like nails and expansion bolts to the walls. This is especially true when attaching and securing objects to interior and exterior building walls, particularly large items like air conditioner units, cabinets, and radiators, requiring additional expansion bolts or nails can be used to mitigate these issues. However, excessive installation of expansion bolts, excessive nailing, or improper handling can not only damage the wall structure but can also cause already fragile objects to loosen or fall off, resulting in property damage and personal injury. Summary of the Invention

[0003] To address the above-mentioned issues, the present invention provides a pre-embedded wall mounting base and a dedicated mounting key. The mounting base is a columnar structure made of building cementitious material, with a circular or polygonal cross-section. The mounting base can be inserted into openings in the outer and inner walls of a wall, thereby penetrating the wall. Alternatively, the mounting base can be inserted into an opening in the outer wall and bonded to the inner wall, thereby providing a non-penetrating installation.

[0004] To improve installation efficiency and ease of installation of the aforementioned pre-embedded wall mount, a keyhole is provided on the outer end surface of the mounting base column. This keyhole is used in conjunction with a dedicated installation key to secure the mounting base to the wall. The key has a key head, the number and shape of which match the number and shape of the key holes. The key heads are connected by a connecting device, which is equipped with a drive connecting rod.

[0005] In order to enhance the bonding strength between the mounting base and the inner wall of the wall, a wall pulling structure is provided on the inner side of the column of the mounting base.

[0006] Specifically, 1. the pull-connection structure is a rubber storage tank provided on the inner end surface of the mounting base column. 2. the pull-connection structure is a self-tapping screw provided on the inner end surface of the mounting base column. 3. the pull-connection structure is a tenon provided on the inner end surface of the mounting base column.

[0007] In order to enhance the bonding strength between the mounting base and the opening of the outer wall of the wall, a clamping structure is provided on the outer side of the column of the mounting base.

[0008] Specifically, first, the fixing structure is a fixing ring provided at the front end of the outer body of the mounting seat column; second, the fixing structure is an anti-rotation groove provided at the front end of the outer body of the mounting seat column.

[0009] In order to improve the firmness and convenience of the connection between the pre-embedded wall mounting base provided by the present invention and the external hanging object, an external connection device is provided in the column of the mounting base.

[0010] Specifically, 1. the external connection device is a nut fixed on the outer side of the mounting base column; 2. the external connection device is a screw fixed on the outer side of the mounting base column; 3. the external connection device is hardwood fixed inside the mounting base column; 4. the external connection device is a metal pipe fixed inside the mounting base column.

[0011] In order to prevent the mounting base from being broken or damaged during the installation process with the wall or the process of hanging external objects, the mounting base is a composite structure with an outer shell installed on the outside, and the outer shell can be made of plastic, PVC or ABS material.

[0012] To enhance the stability of the connection between the mounting base and the wall while further improving installation convenience, the present invention provides a pre-embedded wall mounting base further equipped with a slotting device. Specifically, the slotting device includes a rubber storage groove provided on the inner end surface of the column and a slotting blade. Specifically, the slotting device also includes a self-tapping screw disposed in the rubber storage groove.

[0013] The beneficial effect of the present invention is that the mounting base is suitable for hanging external objects on hollow or solid lightweight interior and exterior walls of buildings. It is made of building cementitious materials and has excellent adhesion to the building wall and building adhesive slurry, and the adhesion is firm. During the installation of the mounting base on the wall, the process is simple, efficient, and does not damage the wall structure. The external connection device provided in the mounting base is suitable for the connection method and connection process currently used for walls and external objects, and not only has high hanging force but also is simple to operate. The mounting base can be produced on a large scale in a factory, which is more in line with environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention provides a wall embedded mounting seat and a special mounting key. Figure 1 The mounting base 1 is a columnar structure made of a building cementitious material with a circular or polygonal cross-section. The mounting base 1 is inserted into an opening 2a in the outer wall and an opening 2b in the inner wall of the wall 2, thereby penetrating the wall. Alternatively, the mounting base 1 is inserted into the opening 2a in the outer wall of the wall 2 and bonded to the inner wall of the wall 2, thereby not penetrating the wall.

[0033] The outer end surface of the mounting base 1 is provided with a mounting key hole 1a, which is arranged symmetrically or in a right triangle shape. When the mounting base 1 is set to penetrate the wall, the mounting key hole 1a can be set on both the inner and outer end surfaces of the mounting base 1.

[0034] In order to enhance the bonding strength between the mounting base 1 and the inner wall of the wall 2 in a non-through-wall setting, a wall pulling structure is provided on the inner side of the column of the mounting base 1 .

[0035] Specifically, Figure 2 The pulling structure shown is a glue storage tank 1b arranged on the inner end face of the column of the mounting seat 1. When the mounting seat 1 is not set through the wall 2, the glue storage tank is filled with adhesive slurry to increase the bonding area and connection strength between the inner end face of the mounting seat 1 and the inner wall of the wall 2.

[0036] Specifically, Figure 3 The pulling structure shown is a self-tapping screw 1c arranged on the inner end surface of the column of the mounting seat 1. When the mounting seat 1 is not set through the wall 2, the self-tapping screw 1c is screwed into the inner wall of the wall 2 to enhance the bonding strength between the two.

[0037] Specifically, Figure 4 The pulling structure shown is a tenon 1d provided on the inner end surface of the column of the mounting base 1, and the tenon 1d is inserted into a circular groove 2c pre-set on the inner wall of the wall 2 to increase the contact surface between the two and enhance the bonding strength.

[0038] In order to enhance the bonding strength of the mounting base 1 with the opening 2a of the outer wall or the opening 2b of the inner wall of the wall 2 in a through-wall or non-through-wall setting, a fixing structure is provided on the outer side of the column of the mounting base 1.

[0039] The aforementioned securing structures can be provided simultaneously on both the inner and outer end surfaces of the mounting base 1. When the mounting base 1 is installed through a wall, the aforementioned securing structures serve to enhance the bonding strength between the mounting base 1 and the openings 2a and 2b of the wall 2. When the mounting base 1 is not installed through a wall, the securing structures on the outer side of the column serve to enhance the bonding strength between the mounting base 1 and the opening 2a of the wall 2. The securing structures on the inner side of the column serve the same function as the aforementioned tensioning structures.

[0040] Specifically, Figure 4 The fixing structure shown is a fixing ring 1i provided at the front end of the cylindrical body of the mounting seat 1.

[0041] The retaining ring 1i is positioned at the outer front end of the column, and its outer diameter is slightly smaller than the openings 2a and 2b in the wall 2. After the mounting base 1 is attached to the wall 2, adhesive slurry is filled into the opening 2a. The retaining ring 1i not only prevents excessive leakage of adhesive slurry into the wall, but also increases the bonding area and strength between the mounting base 1 and the opening 2a.

[0042] Specifically, Figure 4 Figure 6 The securing structure shown is an anti-rotation groove 1j provided at the front end of the cylindrical portion of the mounting base 1. After the mounting base 1 is attached to the wall 2, adhesive slurry is filled into the opening 2a. After curing, the adhesive slurry forms a convex tooth shape within the opening 2a of the wall 2 and the mounting base 1. This not only increases the contact area between the mounting base 1 and the opening 2a of the wall 2, but also prevents the mounting base 1 from accidentally rotating within the opening 2a of the wall 2 due to cracking of the adhesive slurry in a dry environment.

[0043] In order to improve the firmness and convenience of the connection between the pre-embedded wall mounting base provided by the present invention and the external object, an external connection device is provided in the column of the mounting base 1. When the mounting base 1 is installed to penetrate the wall, the external connection device can be provided on both the inner and outer end surfaces of the mounting base 1.

[0044] Specifically, Figure 7 The external connection device shown is a nut 1e fixed on the outer side surface of the column of the mounting base 1, and the nut 1e can be connected to the external object through an external screw.

[0045] Specifically, Figure 8 The external connection device shown is a screw rod 1f fixed on the outer side surface of the column of the mounting base 1, and the screw rod 1f can be connected to the external object through an external nut.

[0046] Specifically, Figure 9 The external connection device shown is a hardwood 1g fixed in the column of the mounting base 1. The hardwood 1g can be connected to the external object by nailing various steel nails or screwing screws.

[0047] Specifically, Figure 10 The external connection device shown is a metal tube 1h fixed in the column of the mounting seat 1. Expansion screws or other expansion devices can be installed in the metal tube 1h to connect with the external object.

[0048] To prevent the mounting base 1 from being broken or damaged during the installation process with the wall 2 or when external objects are hung. Figure 11 Figure 12 The mounting base 1 shown is a composite structure with an outer shell 12 installed on the outside. The outer shell can be made of plastic, PVC or ABS material.

[0049] In order to improve the stability of the connection between the mounting base 1 and the wall 2 while further improving the convenience of installation, the wall embedded mounting base provided by the present invention is further provided with a slotting device 11.

[0050] Specifically, Figure 13 Figure 14 The mounting base 1 is shown as having a slotting device 11 disposed on the inner side of the column. The slotting device 11 includes a glue storage groove 11a and a slotting blade 11b disposed on the inner side end surface of the column of the mounting base 1. During the installation process of the mounting base 1 and the wall 2, adhesive slurry is first applied to the glue storage groove 11a of the mounting base 1. The mounting base 1 is then rotated within the opening 2a of the wall 2 by means of its dedicated installation key. The slotting blade 11b disposed on the inner side end surface of the column of the mounting base 1 mills an annular groove 2c on the inner wall of the wall 2. The annular protrusion on the inner side of the annular groove 2c is inserted into the glue storage groove 11a of the mounting base 1, and the two are bonded and fixed together by the adhesive slurry. Excess adhesive slurry in the glue storage groove 11a is squeezed out into the annular groove 2c, further bonding and fixing the mounting base 1 to the wall 2.

[0051] To improve the positioning accuracy and rotation stability of the mounting base 1 when rotating in the opening 2a of the wall 2.

[0052] Preferably, Figure 15 The slotting device 11 further includes a self-tapping screw 1c disposed in the glue storage groove 11a. When the mounting base 1 rotates in the opening 2a of the wall 2, the self-tapping screw 1c is first screwed into the inner wall of the wall 2 to achieve a positioning function.

[0053] In order to solve the problem of improving the installation convenience and efficiency of the above-mentioned pre-embedded wall mounting seat during the wall installation process, the present invention also provides a special installation key for the pre-embedded wall mounting seat.

[0054] Specifically, Figure 16 Figure 17 Figure 18 The installation key 13 is provided with a key head Aa, and the number and shape of the key head Aa match the number and shape of the installation key insertion holes 1a of the above-mentioned mounting seat 1.

[0055] The plurality of key heads Aa are connected via a connecting device, and a driving connecting rod is provided on the connecting device.

[0056] Specifically, Example 1 Figure 16 The connecting device shown is a straight connecting rod Ab. Figure 17 The connecting device shown is a three-link Ae. Figure 18 The connecting device shown is a connecting plate Ag.

[0057] Specifically, Example 1 Example 2 Figure 16 Figure 17 The driving connecting rod shown in the figure is composed of a rotating rod Ac and a hand-operated rod Ad. Figure 18 The driving connecting rod shown is a regular triangle clamping rod Af, and the triangle bracket rod Af is used to connect with the drill chuck of the power tool.

[0058] The above is a detailed introduction to a pre-embedded wall mounting base and dedicated mounting key solution provided by an embodiment of the present invention. Those skilled in the art will appreciate that variations in the specific implementation and scope of application are possible based on the principles of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention; any modifications based on the design principles of the present invention are within the scope of protection of the present invention.
