Description

Technical Field

[0001] This application relates to the field of interior decoration, and in particular to a protective structure for the external corners of interior walls in building construction projects. Background Technology

[0002] An external corner, a term used in the construction industry, refers to a protruding corner on a wall. In interior decoration, external corners are the most vulnerable to bumps and wear, and therefore usually require special protection. The main purpose of setting up corner protection strips (external corner guards) is to solve the problem of easy damage to protruding wall corners (external corners) in daily use, while taking into account safety, aesthetics, and functionality.

[0003] Traditional corner strips have an L-shaped cross-section, with the two right-angled sides directly fixed to the two right-angled sides of the wall corner by adhesive bonding.

[0004] Traditional L-shaped corner strips are fixed by direct adhesive bonding. Although the construction is simple, it has the following significant drawbacks: 1. The bonding strength between the adhesive (such as silicone or epoxy resin) and the wall surface is usually 1.5-3 MPa. When removing it, it is easy to damage the wall base. Re-attaching requires thorough cleaning of residual adhesive; 2. When the room temperature is below 10 degrees Celsius, the curing time of epoxy resin is extended by 3-5 times. Silicone glue may not be fully cured. Before the glue is cured, the corner strip is easy to shift, and auxiliary fixing measures are required. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a protective structure for the external corners of interior walls in building construction projects.

[0006] The technical solution provided in this application for an interior wall corner protection structure in building construction is as follows: An interior wall corner protection structure for building construction includes two supports arranged vertically and vertically, and a corner guard strip detachably installed between the two supports. Each support has a limiting component for fixing the corner guard strip at one end close to the other. Both the supports and the corner guard strip are L-shaped. Each of the two supports has a limiting groove at one end close to the other. A limiting block is slidably inserted into the limiting groove, and the end of the limiting block abuts against the corner guard strip.

[0007] By adopting the above technical solution, the upper and lower supports need to be fixedly installed on the wall first. Then, the corner guard strip is snapped between the two supports. Next, the limiting block is inserted into the limiting groove so that the end of the limiting block abuts against the corner guard strip, thereby achieving the purpose of locking the corner guard strip. This device can quickly install the corner guard strip, and the disassembly is the reverse of the above process, which will not be elaborated. The disassembly process is also relatively quick and convenient, and will not damage the wall surface during disassembly.

[0008] Preferably, the length of the limiting block is greater than the depth of the limiting groove, both the limiting block and the limiting groove are cross-shaped, and the size of the limiting block is adapted to the limiting groove.

[0009] By adopting the above technical solution, the length of the limiting block is greater than the depth of the limiting groove, ensuring that the end of the limiting block can squeeze and limit the corner guard strip, and stably press and fix the corner guard strip; both the limiting block and the limiting groove are cross-shaped, ensuring that the limiting block will not fall off naturally from the limiting groove from the direction perpendicular to the wall, so that the limiting block can stably press and fix the corner guard strip.

[0010] Preferably, magnet blocks are embedded in the inner walls of both sides of the limiting groove, and the magnet blocks can attract the limiting blocks.

[0011] By adopting the above technical solution, the magnet provides continuous adsorption force, preventing the limiting block from falling out of the limiting groove, improving the installation stability of the limiting block, and thus improving the stability of locking the corner guard strip.

[0012] Preferably, a rubber pad is fixedly connected to the side wall of the corner protector closest to the wall.

[0013] By adopting the above technical solution, a rubber pad buffer layer (thickness ≥ 2mm) is added to absorb impact energy, reducing the stress impact on the wall surface during collision, thereby protecting the corner of the wall.

[0014] Preferably, the thickness of the corner protector strip is less than the thickness of the two supports.

[0015] By adopting the above technical solution, it is to ensure that the corner protector strip can be positioned between the two supports, improve the clamping effect between the supports and the corner protector strip, and further prevent the corner protector strip from accidentally falling off.

[0016] Preferably, the support is fixed to the wall by expansion bolts.

[0017] By adopting the above technical solution, the pull-out force of M8 expansion bolts in C30 concrete can reach 6-8kN, which is far greater than that of structural adhesive. The bolts can bear force immediately after being tightened without waiting for curing. If deviations are found after installation, the position can be finely adjusted.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. First, the upper and lower supports need to be fixedly installed on the wall. Then, the corner guard strip is snapped between the two supports. Next, the limiting block is inserted into the limiting groove so that the end of the limiting block abuts against the corner guard strip, thereby locking the corner guard strip. This device can quickly install the corner guard strip, and the disassembly is the reverse of the above process, which will not be elaborated here. The disassembly process is also relatively quick and convenient, and will not damage the wall surface during disassembly.

[0019] 2. When the room temperature is below 10 degrees Celsius, the curing time of epoxy resin is extended by 3-5 times, and silicone sealant may not be fully cured. Before the adhesive is cured, the corner strip is prone to displacement and auxiliary fixing measures are required. However, this device is suitable for room temperature below 10 degrees Celsius, does not require waiting for curing time, and can quickly complete the installation work. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses an interior wall corner protection structure for building construction, including two supports 3 arranged vertically and vertically, and a corner guard strip 1 detachably installed between the two supports 3. Each of the supports 3 has a limiting component for fixing the corner guard strip 1 at one end close to each other. Both the supports 3 and the corner guard strip 1 are L-shaped. Each of the two supports 3 has a limiting groove 301 at one end close to each other. A limiting block 5 is slidably inserted into the limiting groove 301, and the end of the limiting block 5 abuts against the corner guard strip 1.

[0024] First, the upper and lower supports 3 need to be fixedly installed on the wall. Then, the corner protector 1 is snapped between the two supports 3. Next, each limiting block 5 is inserted into the limiting groove 301 in sequence, so that the end of the limiting block 5 abuts against the corner protector 1, thereby achieving the purpose of locking the corner protector 1. This device can quickly install the corner protector 1, and the disassembly process is the reverse of the above process, which will not be described in detail. The disassembly process is also relatively quick and convenient. The disassembly will not damage the wall surface, and a new corner protector 1 can be quickly replaced.

[0025] Reference Figure 3 The length of the limiting block 5 is greater than the depth of the limiting groove 301. Both the limiting block 5 and the limiting groove 301 are cross-shaped, and the size of the limiting block 5 is adapted to the limiting groove 301.

[0026] The length of the limiting block 5 is greater than the depth of the limiting groove 301, ensuring that the end of the limiting block 5 can squeeze and limit the corner guard strip 1, thus providing stable pressing and fixing of the corner guard strip 1; both the limiting block 5 and the limiting groove 301 are cross-shaped, ensuring that the limiting block 5 will not fall off naturally from the limiting groove 301 from the direction perpendicular to the wall, so that the limiting block 5 can stably press and fix the corner guard strip 1.

[0027] Reference Figure 3 Magnet blocks 4 are embedded in the inner walls of both sides of the limiting groove 301. The magnet blocks 4 can attract the limiting blocks 5. The limiting blocks 5 are made of materials containing iron, nickel, cobalt or their alloys. The magnet blocks 4 have a strong attraction to the above materials.

[0028] The magnet 4 provides a continuous adsorption force, which prevents the limit block 5 from falling out of the limit groove 301 after the limit block 5 is inserted into the limit groove 301, thereby improving the installation stability of the limit block 5 and thus improving the stability of locking the corner guard strip 1.

[0029] Reference Figure 2 A rubber pad 2 is fixedly connected to the side wall of the corner guard strip 1 closest to the wall 6.

[0030] Adding a rubber pad buffer layer (thickness ≥ 2mm) absorbs impact energy and reduces the stress on the wall surface during collision, thereby protecting the corners of the wall.

[0031] Reference Figure 1 The thickness of the corner guard strip 1 is less than the thickness of the two supports 3.

[0032] This is to ensure that the corner protector strip 1 can be positioned between the two supports 3, thereby improving the clamping effect between the supports 3 and the corner protector strip 1 and further preventing the corner protector strip 1 from accidentally falling off; the corner protector strip 1 is made of one of the following materials: aluminum alloy, stainless steel, or polyvinyl chloride.

[0033] Reference Figure 3 The support 3 is fixed to the wall 6 by expansion bolts.

[0034] Expansion bolts can withstand tensile forces of 6-8 kN in C30 concrete, far exceeding those of structural adhesives. They can bear force immediately after being tightened without waiting for curing. If deviations are found after installation, their positions can be finely adjusted. Metal bolts do not age or become brittle over time like adhesives. Bolt fixing facilitates later replacement or adjustment, while structural adhesive removal will damage the substrate.

[0035] The implementation principle of an interior wall corner protection structure for a building construction project according to an embodiment of this application is as follows: Before installation, measure the length between the two supports 3 using a measuring tape to ensure that the corner guard strip 1 fits perfectly. During installation, first, fix the upper and lower supports 3 to the wall, with the lower support 3 close to the ground and the upper support 3 positioned as needed. Then, snap the corner guard strip 1 between the two supports 3. Next, insert each limiting block 5 into the limiting groove 301 in sequence, so that the end of the limiting block 5 abuts against the corner guard strip 1, thus locking the corner guard strip 1. This device can quickly install the corner guard strip 1, and the disassembly process is the reverse of the above process, which will not be elaborated here. The disassembly process is also relatively quick and convenient, and will not damage the wall surface during disassembly. New corner guard strips 1 can be quickly replaced.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
