Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to a method for preparing a foamed ceramic composite wall panel. Background Technology

[0002] Foamed ceramic panels are made from raw materials such as stone powder, fly ash, polishing slag, construction waste, clay, and foaming agents, which are wet-milled, dried, and then fired at high temperatures to create foam. Foamed ceramic panels have advantages such as being lightweight, sound-insulating, heat-insulating, energy-saving, and environmentally friendly. They also possess excellent physical properties such as a low coefficient of thermal expansion, fire resistance, non-combustibility, and corrosion resistance, as well as good mechanical properties such as compressive and shear strength.

[0003] Currently, the application of foamed ceramic panels is mainly limited to interior partition walls. When applied to exterior walls, a single layer of foamed ceramic panels usually cannot meet the requirements. To ensure properties such as fire resistance, load-bearing capacity, and deformation capacity, applying foamed ceramic panels to exterior walls requires the installation of rock wool layers and supporting framing within the wall structure. Finally, after combining the inner and outer foamed ceramic panels with other panels, bolts or self-tapping screws are needed to connect the composite panels. This process is inefficient, hindering production cost reduction. Furthermore, the use of bolts or self-tapping screws to connect the panels detracts from the aesthetics of the composite wall panel and may even affect assembly and installation. Summary of the Invention

[0009] Preferably, in step S5, the positioning bracket includes a groove-shaped seat with a flared opening at one end, and a positioning rib is welded to the groove side of the groove-shaped seat.

[0010] Preferably, in step S5, the installation method of the positioning bracket is as follows: first, a positioning groove for the bracket is opened on the outer foamed ceramic substrate so that the positioning groove for the bracket is connected to the groove of the outer plate; then, the positioning rib for the bracket is placed in the positioning groove for the bracket, and the positioning rib for the bracket is welded to the outer steel mesh embedded in the groove of the outer plate.

[0011] Preferably, in step S5, the positioning clamp includes a positioning bolt and a clamp positioning rib welded to the end of the positioning bolt rod.

Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0019] like Figures 1 to 6 As shown, the preparation method of foamed ceramic composite wall panels includes the following steps: S1. Preparation of substrate: Reference Figure 1 An outer foamed ceramic substrate 11 and an inner foamed ceramic substrate 21 are prepared respectively. An outer frame support 12 is formed at each of the four edges of the outer foamed ceramic substrate 11, and an inner frame support 22 is formed at each of the four edges of the inner foamed ceramic substrate 21. In this embodiment, windows are formed at the centers of the outer foamed ceramic substrate 11 and the inner foamed ceramic substrate 21 respectively. Of course, windows may not be provided; this design is based on engineering needs and should all fall within the protection scope of this invention. S2. Create a recessed groove: (Refer to...) Figure 2 An interleaved outer panel groove 13 is provided on the inner side of the outer foamed ceramic substrate 11, and an interleaved inner panel groove 23 is provided on the outer side of the inner foamed ceramic substrate 21. S3, Mounting Frame: Reference Figure 3 The outer metal frame 14 is installed at the outer frame support 12 of the outer foamed ceramic substrate 11, and the inner metal frame 24 is installed at the inner frame support 22 of the inner foamed ceramic substrate 21; the outer window frame 15 is installed at the window of the outer foamed ceramic substrate 11, and the inner window frame 25 is installed at the window of the inner foamed ceramic substrate 21. S4. Welding steel mesh: Place the steel bars into the groove 13 of the outer plate, and weld them at the intersections to form an outer steel mesh. Weld the outer steel mesh to the outer metal frame 14. Place the steel bars into the groove 23 of the inner plate, and weld them at the intersections to form an inner steel mesh. Weld the inner steel mesh to the inner metal frame 24. S5. Installation positioning components: (Refer to...) Figure 4 Four to six positioning brackets 16 are installed on the inner side of the outer foamed ceramic substrate 11 and welded to the outer steel mesh; a corresponding number of positioning heads 26 are installed on the outer side of the inner foamed ceramic substrate 21 and welded to the inner steel mesh, wherein the positioning heads 26 and the positioning brackets 16 can be engaged. S6. Filling the grooves: Fill the outer panel groove 13 and the inner panel groove 23 with cement grout and completely fill them; S7, Laying Fill Layer: Reference Figure 5 An outer filling layer 17 is laid flat on the inner side of the outer foamed ceramic substrate 11, and the positioning card 16 is cut out to expose the position, thus preparing an outer foamed ceramic wall panel 10; an inner filling layer 27 is laid flat on the outer side of the inner foamed ceramic substrate 21, and the positioning card 26 is cut out to expose the position, thus preparing an inner foamed ceramic wall panel 20; both the outer filling layer 17 and the inner filling layer 27 are preferably made of glass wool, but rock wool or aerogel can also be used.

[0020] S8. Joint welding: Reference Figure 6 After the outer foamed ceramic wall panel 10 and the inner foamed ceramic wall panel 20 are spliced ​​and positioned by the positioning bracket 16 and the positioning bracket 26, the outer metal frame 14 and the inner metal frame 24 are welded together, and the outer window frame 15 and the inner window frame 25 are welded together to obtain the foamed ceramic composite wall panel.

[0021] refer to Figure 7 In this embodiment, the positioning bracket 16 includes a groove-shaped seat 161 with a flared opening 163 at one end, and a bracket positioning rib 162 is welded to the groove side of the groove-shaped seat 161. The installation method of the positioning bracket 16 is as follows: First, a bracket positioning groove 18 is opened on the outer foamed ceramic substrate 11, so that the bracket positioning groove 18 is connected to the outer plate embedding groove 13. Then, the bracket positioning rib 162 is placed in the bracket positioning groove 18, and the bracket positioning rib 162 is welded to the outer steel mesh embedded in the outer plate embedding groove 13. This facilitates the positioning and installation of the positioning bracket 16, and connects the positioning bracket 16 to the outer steel mesh through the bracket positioning rib 162, which greatly improves the stress performance of the joint.

[0022] refer to Figure 8 and Figure 9In this embodiment, the positioning clamp 26 includes a positioning bolt 261 and a clamp positioning rib 262 welded to the end of the positioning bolt 261. The rib of the positioning bolt 261 can enter from the flared opening 163 of the positioning clamp seat 16, thereby allowing the head end of the positioning bolt 261 to engage with the groove-shaped seat 161. The installation method of the positioning clamp 26 is similar to that of the positioning clamp seat 16, specifically as follows: First, a clamp positioning groove 28 is opened on the inner foamed ceramic substrate 21, so that the clamp positioning groove 28 is connected to the inner plate groove 23. Then, the clamp positioning rib 262 is placed in the clamp positioning groove 28, and the clamp positioning rib 262 is welded to the inner steel mesh embedded in the inner plate groove 23. This facilitates installation and improves the stress performance of the joint.

[0023] refer to Figure 9 and Figure 10 The splicing and positioning method of the outer foamed ceramic wall panel 10 and the inner foamed ceramic wall panel 20 is as follows: Lay the outer foamed ceramic wall panel 10 flat with its inner side facing upwards. Place the outer side of the inner foamed ceramic wall panel 20 facing the inner side of the outer foamed ceramic wall panel 10. Horizontally adjust the inner foamed ceramic wall panel 20 so that the positioning clip 26 aligns with the positioning bracket 16 of the outer foamed ceramic wall panel 10. Then, horizontally move the inner foamed ceramic wall panel 20 until the positioning clip 26 is engaged with the positioning bracket 16. This achieves the splicing and positioning of the outer foamed ceramic wall panel 10 and the inner foamed ceramic wall panel 20. This positioning-type mortise and tenon structure splicing of the outer and inner foamed ceramic wall panels improves the seismic performance of the splicing joint, meeting the seismic fortification requirements of intensity 8.

[0024] This method first prepares externally foamed ceramic wall panels and internally foamed ceramic wall panels, and then splices and combines them using positioning brackets and positioning heads. The double-splicing design facilitates factory prefabrication and on-site assembly, shortens the construction period, reduces construction waste and dust pollution, conforms to the policy guidance of prefabricated buildings, promotes the development of prefabricated buildings, facilitates standardized construction, and greatly improves equipment utilization.

[0025] Foamed ceramics are A1-grade non-combustible materials. By combining inner and outer double-layer foamed ceramic panels with a lightweight filler layer, the strength and functionality of the wall panel can be balanced, overcoming the limitations of traditional single-material performance. The composite structure can meet the fire protection specifications for high-rise buildings, reducing the risk of fire. It is lightweight, easy to construct, has good thermal insulation, excellent sound insulation, and good overall seismic resistance. The raw materials do not release harmful substances such as asbestos and formaldehyde, which helps improve indoor air quality and enhance building safety and comfort.

[0026] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
