Technical Field
[0001] This invention relates to the technical field of interior stone decorative columns in building interior decoration, specifically to a prefabricated back-bolted stone decorative column. Background Technology
[0002] In the field of modern architectural decoration, stone is widely used for the decoration of interior and exterior columns due to its natural texture, noble color, and excellent durability. Among them, prefabricated stone decorative columns using back-bolted dry-hanging technology have become the mainstream choice due to their convenient installation and structural stability. However, when implementing right-angle corners of stone decorative columns, existing technical solutions have obvious aesthetic and structural defects, mainly reflected in the following aspects: Firstly, inconsistent materials and poor aesthetics: The most common practice is to use filler light troughs (such as LED light strips) or prefabricated beveled parts made of non-stone materials (such as plastic, wood, etc.) to fill and transition at the right-angle joint of two vertical stone panels. Although this approach simplifies installation, it seriously damages the overall material uniformity and visual integrity of the stone column. The color difference, texture, and aging rate of different materials result in obvious "scars" at the corners, greatly affecting the overall aesthetic effect pursued by high-end stone decoration. Secondly, the complex structure and difficult installation present challenges: To achieve a pure stone effect, another approach is to use separately processed stone corner components, directly fixed to the steel frame via a dry-hanging system. However, this presents installation difficulties. In the extremely confined space of the column corner, the heavy and fragile stone corner components must be precisely aligned and dry-hanged onto the steel frame, making the operation extremely difficult, inefficient, and posing a high risk of damage. The installation precision requirements for the steel frame also become extremely stringent. Therefore, a stone decorative column is needed that ensures material uniformity and aesthetic appeal at the corners, while also possessing a simple structure, convenient processing, and easy installation. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the above-mentioned situation by proposing a prefabricated back-bolted stone decorative column that can ensure the uniformity of material and aesthetic appeal at the corners of the stone decorative column, while also possessing a simple structure, convenient processing, and easy installation.
[0004] To achieve the above objectives, the technical solution of this invention is as follows: a prefabricated back-bolted stone decorative column, comprising: a structural square column, on which steel frames, stone back-bolt dry-hanging components, and stone panels are respectively provided on the four sides; at the right-angle joint position of adjacent stone panels, corner stone inserts, L-shaped back-bolt brackets, and corner back bolts are provided. The corner stone insert is integrally formed from the outer side of the right-angled arc surface and the inner side of the overlapping block. During assembly, after the stone panels are dry-hanging in place, the corner stone inserts are tightly inserted into the corner gap between two adjacent stone panels. The first corner back bolt passes through the L-shaped back-bolt bracket one and connects to the stone panel on one side; the second corner back bolt passes through the L-shaped back-bolt bracket one and connects to the corresponding surface of the overlapping block; the third corner back bolt passes through the L-shaped back-bolt bracket two and connects to the stone panel on the other side; and the fourth corner back bolt passes through the L-shaped back-bolt bracket two and connects to the corresponding surface of the overlapping block.
[0005] The steel frame includes: square tube columns, L-shaped connecting steel angle brackets, angle steel beams, embedded steel plates, expansion bolts, and angle steel columns. The expansion bolts fix the embedded steel plates to the designated positions on the sides of the structural square columns. The L-shaped connecting steel angle brackets are welded and fixed to the square tube columns and the embedded steel plates respectively. The inner ends of the angle steel beams are welded to the square tube columns, and the outer ends of the angle steel beams are welded to the corresponding sides of the angle steel columns located at the corner positions.
[0006] The stone back-bolt dry-hanging assembly includes: stone back bolts, stainless steel stone hangers, height adjustment screws, stainless steel brackets, and locking bolts. The stainless steel brackets are fixed to the angle steel beams by the locking bolts. The stone back bolts fix the stainless steel stone hangers to the back of the stone panel. The stainless steel stone hangers are attached to the stainless steel brackets. The height adjustment screws are threaded between the stainless steel stone hangers and the stainless steel brackets.
[0007] The stainless steel support is provided with lateral fine-tuning serrations to fine-tune the extension distance of the stainless steel support.
[0008] The stainless steel mounting bracket and the stainless steel stone mounting bracket have mutually staggered upper and lower mounting positions.
[0009] Stone structural adhesive is sandwiched between the L-shaped back bolt corner bracket and the corresponding position of the stone panel.
[0010] The angle steel column and the corner square tube column are welded together, wherein the angle steel column is welded to the angle steel beam on one side, and the corner square tube column is welded to the angle steel beam on the other side.
[0011] The joint between the corner stone insert and the two adjacent stone panels is filled with grout of the same color.
[0012] A metal skirting board is recessed between the lowest stone panel and the decorative floor.
[0013] The top surface of the highest stone panel is fitted with a sealing plate with stainless steel edging.
[0014] With the above structure, this new invention has the following characteristics:
[0015] 1. By using corner stone inserts, the corner area and the column surface are made of the same stone material, eliminating the visual disjointedness caused by the traditional use of non-stone fillers or light troughs, and ensuring the integrity and high-end aesthetics of the decorative column.
[0016] 2. The corner stone insert has a simple structure, consisting of an integrally formed component with overlapping blocks, which completely avoids the complex and expensive irregular processing of traditional L-shaped integral stone corners, greatly reducing processing difficulty and cost.
[0017] 3. By adopting the installation sequence of "hanging the panels first and then inserting the corners", the most complicated corner operation is transformed into a simple plug-in and back bolt fixation, which perfectly avoids the problem of dry-hanging heavy integral stone corners in narrow spaces, making construction safe and efficient.
[0018] 4. The corner stone insert is firmly connected to the two adjacent stone panels by L-shaped back bolt corner brackets, forming a stable triangular force transmission system, ensuring that the corner node is as reliable as the overall dry-hanging system.
[0019] 5. Thanks to the back-bolt dry-hanging system consistent with the main body, this corner structure inherits the system's three-dimensional adjustment capability, which can effectively absorb construction errors and ensure installation accuracy. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of this novel invention will be described in further detail.
[0028] This novel embodiment is: a prefabricated back-bolted stone decorative column, comprising: a structural square column 1, with a steel frame 2, a stone back-bolted dry-hanging assembly 3, and a stone panel 4 respectively provided on the four sides of the structural square column 1; at the right-angle joint position perpendicular to adjacent stone panels 4, corner stone inserts 5, L-shaped back-bolted corner brackets 6, and corner back bolts 7 are provided. The corner stone insert 5 is integrally formed from the outer side 51 of the right-angled arc surface and the inner side of the overlapping square block 52. During assembly, after the stone panel 4 is dry-hanging in place, the corner stone insert 5 is... The corner stone insert 5 is tightly inserted into the corner gap between two adjacent stone panels 4. The first corner back bolt 71 passes through the L-shaped back bolt corner bracket 61 and is connected to the stone panel 4 on one side. The second corner back bolt 72 passes through the L-shaped back bolt corner bracket 61 and is connected to the corresponding surface of the overlapping block 52. The third corner back bolt 73 passes through the L-shaped back bolt corner bracket 62 and is connected to the stone panel 4 on the other side. The fourth corner back bolt 74 passes through the L-shaped back bolt corner bracket 62 and is connected to the corresponding surface of the overlapping block 52.
[0029] The steel frame 2 includes: square tube columns 21, L-shaped connecting steel angle brackets 22, angle steel beams 23, embedded steel plates 24, expansion bolts 25, and angle steel columns 26. The expansion bolts 25 fix the embedded steel plates 24 to a set position on the side of the structural square column 1. The L-shaped connecting steel angle brackets 22 are welded and fixed to the square tube columns 21 and the embedded steel plates 24 respectively. The inner end of the angle steel beams 23 is welded to the square tube columns 21, and the outer end of the angle steel beams 23 is welded to the corresponding side of the angle steel columns 26 set at the corner position.
[0030] The stone back-bolt dry-hanging assembly 3 includes: stone back bolt 31, stone stainless steel hanger 32, height adjustment screw 33, stainless steel support 34, and locking bolt 35. The stainless steel support 34 is fixed to the angle steel beam 23 by the locking bolt 35. The stone back bolt 31 fixes the stone stainless steel hanger 32 to the back of the stone panel 4. The stone stainless steel hanger 32 is hung on the stainless steel support 34. The height adjustment screw 33 is threaded between the stone stainless steel hanger 32 and the stainless steel support 34.
[0031] The stainless steel support 34 is provided with a transverse fine-adjustment serration 341 to fine-tune the extension distance of the stainless steel support 34.
[0032] The stainless steel hanger 34 and the stone stainless steel hanger 32 have mutually offset upper hanging positions 321 and lower hanging positions 342.
[0033] The L-shaped back bolt corner bracket 6 is clamped with stone structural adhesive 8 at the corresponding position of the stone panel 4.
[0034] The angle steel column 26 and the corner square tube column 211 are welded together, wherein the angle steel column 26 is welded to the angle steel beam 23 on one side, and the corner square tube column 211 is welded to the angle steel beam 23 on the other side.
[0035] The joint between the corner stone insert 5 and the two adjacent stone panels 4 is filled with grout of the same color 9.
[0036] A metal skirting board 10 is recessed between the lowest piece of the stone panel 4 and the decorative floor.
[0037] The top surface of the highest piece of the stone panel 4 is provided with a sealing plate 11 with a stainless steel edge strip.
[0038] The core of this new type of prefabricated back-bolted stone decorative column lies in an innovative corner structure, which is implemented according to the following steps:
[0039] Step 1: First, fix the embedded steel plate 24 to the square column 1 of the building structure using expansion bolts 25. Then, weld the square tube column 21 to the embedded steel plate 24 using L-shaped connecting steel angle brackets 22. At the corner of the column, weld the angle steel column 26 to the corner square tube column 211 to form a sturdy corner support. Finally, weld the inner and outer ends of the angle steel beam 23 to the square tube column 21 and the angle steel column 26 respectively, forming a complete load-bearing framework.
[0040] Step 2: Install the stainless steel bracket 34 onto the angle steel beam 23 using locking bolts 35, and use its own lateral fine-tuning serrations 341 to precisely adjust its extension distance to compensate for structural installation errors.
[0041] Step 3: Anchor the stainless steel stone hanger 32 to the back of the stone panel 4 using the stone back bolt 31. Then, hang the stone panel 4 onto the adjusted stainless steel support 34 using its hanger. The vertical height of the stone panel 4 can be finely adjusted by rotating the height adjustment screw 33. Reliable engagement is achieved through the staggered upper and lower hook-and-loop fasteners 321 and 342 on the hanger and support, ensuring a level installation.
[0042] Step 4: Then assemble the corner structure: This is the key step of this new type of assembly. Its core is "hang the panel first, then insert the corner".
[0043] Step 4.1: Install L-shaped back-bolt brackets 6: On the inside of the right-angle joint between two adjacent stone panels 4, use the first corner back bolt 71 and the third corner back bolt 73 to secure the L-shaped back-bolt bracket 61 and L-shaped back-bolt bracket 62 to the predetermined positions on the back of the stone panel 4, respectively. Before installation, apply stone structural adhesive 8 between the L-shaped back-bolt bracket 6 and the stone contact surface to enhance the connection strength and sealing.
[0044] Step 4.2, Insert and fix the corner stone insert 5: Align the outer side 51 of the prefabricated corner stone insert 5, which is a right-angled arc surface, with the inner side being an overlapping block 52, with the corner gap reserved between the two stone panels 4, and insert it into place with a tight joint.
[0045] Step 4.3: Complete the corner connection: Using the second corner back bolt 72 and the fourth corner back bolt 74, pass them through the other wing plates of the L-shaped back bolt bracket 61 and L-shaped back bolt bracket 62, which are already fixed to the stone panel 4, and tighten them onto the corresponding surfaces of the overlapping blocks 52 of the corner stone insert 5. Similarly, apply stone structural adhesive 8 to the contact surfaces of the back bolt brackets and the overlapping blocks 52. At this point, the corner stone insert 5 is firmly connected to the two adjacent stone panels 4 by two L-shaped back bolt brackets 6 distributed at 90 degrees, forming a stable whole.
[0046] Step 5: Fill the joints between all the stone panels 4 and the gaps between the corner stone inserts 5 and the panels with a grout of the same color as the stone. Finally, install the metal skirting board 10 at the column base and install the end plate 11 with stainless steel edge strips at the top of the column to complete the construction of the entire decorative column.
[0047] As can be seen from the above, this new invention transforms the complex corner dry-hanging into a simple plug-in and back bolt fixing through the above-described embodiments, achieving the beneficial effects of simple structure and convenient installation for stone decorative columns while ensuring the overall aesthetics of the stone.
[0048] Of course, this invention may have many other embodiments. Without departing from the spirit and essence of this invention, those skilled in the art can make various corresponding changes and modifications based on the invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
