Description

A prefabricated keel dry-hanging tile installation structure Technical Field

[0001] This utility model relates to the field of wall tile installation technology, specifically to a prefabricated keel dry-hanging tile installation structure. Background Technology

[0002] The most common method for laying wall tiles is to first prepare the base layer by roughening the wall surface, then mark the tiles according to their size and make mortar spots, apply a base coat of mortar, take out the pre-soaked tiles, apply cement mortar to the back of the tiles, and gently tap them with a rubber mallet to ensure they adhere tightly to the wall mortar and remove air bubbles to prevent hollow spots. After the cement mortar has hardened, the tile gaps are then grouted with cement mortar to complete the installation.

[0003] However, the current tile laying process involves many steps, which leads to a corresponding increase in quality problems. For example, if the base layer is not properly prepared, the tiles may fall off completely or become hollow during later use. Due to the limited skill level of the workers, the surface may be uneven. Incorrect cement mortar ratio, insufficient soaking of tiles, and inadequate base plastering can all lead to localized hollowing. If too much cement mortar overflows from the joints, it will increase the time and labor costs spent on grouting later. Summary of the Invention

[0004] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a prefabricated keel dry-hanging tile installation structure, in which tiles are glued to the dry-hanging components with adhesive. The dry-hanging method reduces the occurrence of hollow spots at the tile glued areas. The prefabricated horizontal keel and prefabricated vertical keel are inserted into slots, and the slots provide clear directionality and positioning function for the installation of the keel system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prefabricated keel dry-hanging tile installation structure includes a keel system, dry-hanging components, tiles, and adhesive. The keel system includes prefabricated longitudinal keels and prefabricated horizontal keels. The prefabricated longitudinal keels are fixedly installed on the wall, and through slots are provided on the sides of the prefabricated longitudinal keels. The prefabricated horizontal keels pass through the slots and are inserted into the prefabricated longitudinal keels. The dry-hanging components are installed on the prefabricated horizontal keels, and the tiles are adhered to the dry-hanging components with adhesive.

[0007] As a preferred embodiment, multiple prefabricated longitudinal keels are arranged horizontally, one prefabricated transverse keel passes through the slots of multiple prefabricated longitudinal keels in the same horizontal direction, and multiple prefabricated transverse keels are arranged vertically.

[0008] As a preferred option, the prefabricated longitudinal keel and the prefabricated transverse keel are spot-welded together at the slot to achieve lateral fixation of the prefabricated transverse keel.

[0009] As a preferred option, screw holes are made in the slots of the prefabricated longitudinal keel towards the side away from the wall; blind holes are made on the prefabricated horizontal keel accordingly, and fastening bolts are screwed into the screw holes and then inserted into the blind holes, with the bottom end of the fastening bolts abutting against the bottom surface of the blind holes to achieve the lateral fixation of the prefabricated horizontal keel.

[0010] As a preferred option, the dry-hanging assembly includes a hanger and fixing bolts. The hanger has a concave groove at the end, and mounting holes are opened on the prefabricated horizontal keel. The concave groove at the end is fitted with the prefabricated horizontal keel. The hanger is fixed by the fixing bolts passing vertically through the concave groove at the end and the mounting holes. The tiles are pasted onto the surface of the hanger with adhesive.

[0011] As a preferred option, the adhesive is AB glue.

[0012] As a preferred option, there are multiple dry-hanging components, multiple hanging brackets, and multiple tiles. The four corners of the inner surface of a square tile are respectively pasted onto four hanging brackets.

[0015] As a preferred option, positioning holes are made in the wall, and anchoring adhesive is injected into the positioning holes, with internal thread metal expansion bolts located inside the positioning holes.

[0016] This utility model has the following advantages:

[0017] 1. Precast longitudinal joists are connected via slot-fitting.

[0037] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Example 1

[0039] As shown in Figures 1 to 9 and Figure 12, a prefabricated keel dry-hanging tile installation structure includes a keel system, a dry-hanging component 1, tiles 2, and adhesive 12. The keel system includes prefabricated longitudinal keels 3 and prefabricated horizontal keels 4. The prefabricated longitudinal keels 3 are vertically fixed to the wall 7, with their lower ends abutting the ground. A horizontal through-hole 5 is provided on the side of the prefabricated longitudinal keel 3, through which the prefabricated horizontal keels 4 are inserted. The dry-hanging component 1 is installed on the prefabricated horizontal keels 4, and the tiles 2 are adhered to the dry-hanging component 1 using adhesive 12. This dry-hanging method reduces the occurrence of hollow spots at the tile adhesion points. The slots 5 provide clear directionality and positioning for the installation of the keel system; the slots 5 not only provide initial fixation for the prefabricated horizontal keels 4 but also ensure accurate horizontal positioning of the prefabricated horizontal keels 4. Complex auxiliary positioning operations are not required during the installation of the keel system, avoiding deviations that may occur during manual installation. Before installation, insert the prefabricated horizontal keel 4 into the slot 5, and then support the whole structure against the wall. When installing the prefabricated vertical keel 3, you can support the prefabricated horizontal keel 4, which can reduce the need for auxiliary installation tools.

[0040] The precast longitudinal keel 3, precast horizontal keel 4, dry-hanging component 1, and ceramic tile 2 are all precast standardized prefabricated building components, manufactured in a factory and subjected to rigorous quality testing. Therefore, every component arriving at the construction site meets predetermined standards, providing a foundation for high-precision installation. The standardized component design reduces the need for on-site cutting and adjustments, thereby reducing material waste and aligning with green environmental protection principles. The prefabricated installation method allows for easy replacement of damaged individual components without extensive disassembly, reducing maintenance costs.

[0041] Even with minor errors during actual installation, the slot 5 design allows for adjustments and corrections to ensure final installation accuracy. The slot 5 connection simplifies on-site construction, reduces reliance on highly skilled labor, and minimizes human error. Simultaneously, it improves construction efficiency and shortens the construction period.

[0042] The prefabricated longitudinal keel 3 and prefabricated transverse keel 4 can be made of aluminum alloy. Aluminum alloy is lightweight, easy to handle and install, and is particularly suitable for use in prefabricated buildings. While ensuring structural strength, it can significantly reduce the overall weight of the installed structure.

[0043] Multiple prefabricated longitudinal keels 3 are arranged horizontally, and a prefabricated transverse keel 4 passes through the slots 5 of multiple prefabricated longitudinal keels 3 in the same horizontal direction. The multiple prefabricated transverse keels 4 are arranged vertically. The arrangement and combination of multiple prefabricated longitudinal keels 3 enable the modular installation of the keel system, which facilitates transportation and on-site installation and shortens the construction period.

[0044] The prefabricated longitudinal keel 3 and prefabricated transverse keel 4 are spot-welded together at the slot 5 to achieve lateral fixation of the prefabricated transverse keel 4. This ensures the stability and accuracy of the keel system structure.

[0045] The dry-hanging assembly 1 includes a hanger 6, a nut, and fixing bolts 8. The hanger 6 has a tail-end recessed groove 11 on the side near the precast horizontal keel 4. A vertically penetrating mounting hole is formed on the precast horizontal keel 4. The tail-end recessed groove 11, with its opening facing the wall 7, is fitted onto the precast horizontal keel 4. The fixing bolts 8 pass vertically through the tail-end recessed groove 11 and the mounting hole, and are screwed into the nut located outside the tail-end recessed groove 11 to fix the hanger 6. The tiles 2 are adhered to the surface of the hanger 6 using adhesive 12. Preferably, each hanger 6 has two tail-end recessed grooves 11, and each tail-end recessed groove 11 corresponds to two fixing bolts 8. The fitting of the tail-end recessed groove 11 with the precast horizontal keel 4 ensures precise alignment of the hanger 6 during installation, avoiding errors caused by manual adjustment and thus improving the overall installation accuracy. Multiple mounting holes can be opened on the prefabricated horizontal keel 4. The dry-hanging component 1 can be adjusted to the corresponding mounting hole position according to the size of the tile 2, so that the keel system can be adapted to tiles 2 of various sizes and specifications.

[0046] In this embodiment, the adhesive 12 is preferably AB glue. AB glue is relatively simple to use; simply mix the two components according to the specified ratio and apply evenly to the surface of the hanger 6. AB glue has high bonding strength, high transparency, good weather resistance, and is environmentally friendly and non-toxic. The tiles 2 are fixed using this adhesive method, which is convenient. A grout 13, filled with sealant, is provided between adjacent tiles 2. The grout 13 not only improves aesthetics but also prevents moisture and other debris from entering, extending the lifespan of the tiles 2. In this embodiment, AB glue is used to adhere the tiles 2, and the AB glue is less likely to overflow from the grout 13 between adjacent tiles 2, thus facilitating the subsequent filling of the grout 13 with sealant.

[0047] There are multiple dry-hanging components 1, multiple corresponding hangers 6, and multiple tiles 2. This embodiment does not explicitly specify the number of dry-hanging components 1, hangers 6, and tiles 2; the numbers can be arranged according to the actual site conditions. The four corners of the inner surface of a square tile 2 are respectively pasted onto four hangers 6. Simultaneously, one hanger 6 is pasted onto the corners of two or four tiles 2, forming a uniformly distributed pasting method for the tiles 2 as shown in Figure 7. By setting and fixing hangers 6 at the four corners of the tiles 2, multi-point support and uniform force distribution are achieved. This multi-point fixing method allows the external forces (such as wind pressure, vibration, etc.) borne by each tile 2 to be evenly distributed to each hanger 6, thereby enhancing the overall stability and safety of the system.

[0048] The keel system also includes an L-shaped plate 14, wall-mounted bolts 15, and internally threaded metal expansion bolts 17 that are inserted into the wall 7. One outer side of the L-shaped plate 14 is fixed to the side of the prefabricated longitudinal keel 3, and the other outer side of the L-shaped plate 14 is flush against the wall 7. The wall-mounted bolts 15 pass through the other outer side of the L-shaped plate 14 and are screwed into the internally threaded metal expansion bolts 17. By providing screw-in internally threaded metal expansion bolts 17 within the wall 7, the prefabricated longitudinal keel 3 can be easily assembled and disassembled on-site. When the wall-mounted bolts 15 are tightened, the internally threaded metal expansion bolts 17 expand and embed tightly into the wall, providing strong pull-out resistance and preventing the keel system from detaching from the wall.

[0049] Positioning holes 19 are made in the wall 7, and anchoring adhesive is injected into the positioning holes 19. The internal thread metal expansion bolts 17 are located in the positioning holes 19. The positioning holes 19 ensure the accurate positioning of the internal thread metal expansion bolts 17 in the wall 7, avoiding installation errors caused by positional deviations. This precise positioning method improves the overall installation accuracy. The anchoring adhesive makes the internal thread metal expansion bolts 17 more secure in the positioning holes 19.

[0050] During construction and installation, firstly, insert the precast horizontal keel 4 into the slot 5 of the precast vertical keel 3, as shown in Figure 12. Drill positioning holes 19 on the wall 7 using drill bit 16, inject anchoring adhesive into the positioning holes 19, insert internal thread metal expansion bolts 17, and then pass wall-mounted bolts 15 through L-shaped plates 14. The wall-mounted bolts 15 are screwed into the internal threads of the internal thread metal expansion bolts 17 to fix the precast vertical keel 3. Secondly, install the dry-hanging component 1, set the hanger 6 at the corresponding position of the precast horizontal keel 4, and then tighten the fixing bolts 8. Thirdly, attach the tile 2 to the corresponding hanger 6 with AB glue. When the AB glue has some strength, the position of the tile 2 can be slightly adjusted to meet the verticality and flatness. After the AB glue has completely hardened, the tile 2 will be firmly fixed to the hanger 6. Fourthly, fill the grout 13 with grout, thus completing the construction.

[0051] Example 2

[0052] As shown in Figures 10 and 11, this embodiment differs from Embodiment 1 in that screw holes 9 are made in the slots 5 of the prefabricated longitudinal keel 3, on the side away from the wall 7; blind holes 10 are correspondingly made on the prefabricated horizontal keel 4. Fastening bolts 18 are screwed into the screw holes 9 and then inserted into the blind holes 10. The bottom end of the fastening bolts 18 abuts against the bottom surface of the blind holes 10 to achieve lateral fixation of the prefabricated horizontal keel 4. When tightening the fastening bolts 18, the screw head of the fastening bolts 18 does not tightly adhere to the surface of the prefabricated longitudinal keel 3. On-site welding of the prefabricated longitudinal keel 3 and the prefabricated horizontal keel 4 is unnecessary; lateral fixation of the prefabricated horizontal keel 4 can be achieved simply through the assembly installation of the fastening bolts 18, reducing construction time and simplifying operation.

However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
