Description

Technical Field

[0001] This utility model relates to the field of building decoration, renovation and sound absorption and noise reduction materials, and in particular to a decorative ceiling structure for a deformable sound-absorbing panel. Background Technology

[0002] In the field of architectural decoration, there are currently two main technical approaches to achieve curved surface designs: one is to use GRG (glass fiber reinforced gypsum) or GRC (glass fiber reinforced cement) products, and the other is to use silica ceramic panels. However, both technologies have certain limitations, as detailed below.

[0003] In GRG (Glass Fiber Reinforced Gypsum) and GRC (Glass Fiber Reinforced Cement) curved surface modeling systems, the installation accuracy of the keel directly affects the final molding effect. This type of technology relies on on-site welded steel keels as a supporting framework. However, because the keel bending process depends on manual operation, the angle control error generally exceeds 3°, resulting in a cumulative axial offset of 5~8mm / m between adjacent keels. Especially for hyperboloid shapes, the curvature fit between the base gypsum board and the precast GRG / GRC panel is insufficient, and the measured joint gap is often greater than 3mm, requiring excessive filling with adhesive material for compensation. This not only increases the structural load but also easily induces later cracking. Furthermore, the thermal expansion coefficients of the gypsum substrate and the steel structure differ significantly (1.5×10⁻ ... 5 / ℃ and 1.2×10⁻ 5 At a temperature difference of 10℃, the interface displacement can reach 0.6mm / m, causing periodic cracking of the joint and increasing maintenance costs by more than 30%.

[0004] Although the curved surface structure of the silicon ceramic panel adopts a prefabricated aluminum keel system, its three-dimensional modeling accuracy is still limited by the fine-tuning capability of the connection nodes (±2mm adjustment range). When splicing multiple layers of keels, the misalignment error at the turning points is cumulative. When the deviation of a single node exceeds 4mm, the keel will have to be disassembled and reconstructed, significantly delaying the construction period. During the installation stage, the contradiction between the single curvature bending characteristics of the silicon ceramic panel and the insufficient rigidity of the keel is further highlighted: when the aluminum keel span exceeds 2m, the deflection reaches L / 250, causing the panel surface to exhibit wavy wrinkles and the edge warping rate to exceed 1.5‰. Even if the dimensional tolerance of the panel itself is strictly controlled within ±0.5mm, the cumulative error of the keel still causes the panel joint width dispersion to exceed the tolerance (measured 1~5mm). Even with the use of elastic adhesive joint compensation, more than 30% of the visible joints still affect the aesthetics due to twisting deformation.

[0005] A synthesis of these two technologies reveals a common bottleneck in traditional curved surface shaping systems: the failure to coordinate the control of keel precision and material deformation. Measured keel forming precision using GRG / GRC technology reaches ±3.2mm / m, while the error in the silicon ceramic plate system reaches ±2.8mm / m. Furthermore, this error is exacerbated through multi-layered construction, ultimately leading to excessive installation flatness (GRG: 2.8mm / 2m, silicon ceramic plate: 3.5mm / 2m). More seriously, differences in dynamic deformation result in insufficient system stability, with a high cumulative rate of material interface displacement exceeding limits, directly causing over 30% of projects to require secondary leveling or frequent maintenance. This situation urgently necessitates an innovative technology that can simultaneously improve keel shaping precision and dynamic coordination, breaking through the precision limits and durability bottlenecks of existing processes.

[0006] Through dedicated research and development, the applicant has innovatively developed a deformable sound-absorbing panel. Overcoming the technical challenges of material deformation and installation, the applicant has developed a frame and ceiling structure for a deformable sound-absorbing panel architectural decorative ceiling.

[0013] Furthermore, the irregularly shaped surface of the L-shaped plate is a shaped contour surface, which forms a curved surface with the irregularly shaped surface of the T-shaped plate in two dimensions: longitude and latitude.

[0014] Furthermore, the positioning groove of the second frame unit is used to fix the position of the T-shaped plate, and its notch angle is perpendicular to the molded shape contour surface.

The frame is connected to the support members at both ends via frame units, and the middle section of the frame is connected to the hangers via a frame.

The basic principles of this utility model defined in the following description can be applied to other implementations, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this utility model.

[0032] Example 1

[0033] Depend on Figure 1-7 As shown, a frame 100 for a deformable sound-absorbing panel architectural decorative ceiling structure includes a frame assembly, a curved surface structure assembly, and a reinforcing assembly. The frame assembly includes a first frame unit 1 and a second frame unit 2, with the two first frame units 1 and two second frame units 2 respectively arranged opposite to each other and formed into a rectangular frame structure through welding. The curved surface structure assembly includes a T-shaped plate 3, which is arranged parallel to the first frame unit 1 and its two ends are perpendicularly connected to the second frame unit 2. The reinforcing assembly includes a C-shaped steel 4 and stiffening plates 5, both of which are arranged parallel to the second frame unit 2 and their two ends are perpendicularly connected to the first frame unit.

[0034] Furthermore, all of the frames 100 are made of metal.

[0035] The first frame unit 1 is an L-shaped plate with an irregularly shaped surface 11 and a positioning groove 13 on its long side. The thickness of the first frame unit 1 is 0.5~5mm.

[0036] The second frame unit 2 is formed into a U-shape by welding an L-shaped plate 21 to a non-circular shaped surface 23 of the L-shaped plate 21. The L-shaped plate 21 has a non-circular shaped surface 23 and a positioning groove 25 on its long side. The L-shaped plate 21 has a thickness of 0.5~5mm. The sheet 22 has a width of 15~50mm and a thickness of 0.5~5mm.

[0037] The T-shaped plate 3 includes a vertical plate 31 and a horizontal plate 32, with a thickness of 0.5~5mm; the horizontal plate 32 and the irregularly shaped surface 33 of the vertical plate 31 are welded to form a vertical structure.

[0038] Among them, the irregularly shaped surface 23 of the L-shaped plate 21 is the shaped contour surface, which forms a curved surface with the irregularly shaped surface 33 of the T-shaped plate 3 in two dimensions.

[0039] The positioning groove 25 of the second frame unit 2 is used to fix the position of the T-shaped plate 3. Its notch angle is perpendicular to the molding contour surface, its width is the thickness deviation of the vertical plate 31 of the T-shaped plate + 0.5, and its depth is greater than the height of the vertical plate 31 by 2mm.

[0040] The irregularly shaped surface 33 of the vertical plate 31 is a shaped contour surface, which forms a curved surface with the second frame unit 2 in two dimensions: longitude and latitude.

[0041] The stiffening plate 5 is a strip plate with a thickness of 0.5~5mm. It is composed of a stiffening plate irregular shape surface 51 and a positioning groove 52. It is connected to the T-shaped plate 3 by welding to enhance the rigidity of the frame 100.

[0042] The C-shaped steel 4 is the main reinforcing member. Flexible grooves 42 are provided on one side of its flange and web. When reinforcing the frame 100, a variable curved surface 41 is formed by cold bending. After it matches the outline of the frame 100, it is closed and welded to consolidate the shape of the frame 100.

[0043] Example 2

[0044] Depend on Figure 8-10 As shown, a deformable sound-absorbing panel architectural decorative ceiling structure includes a frame 100, a support member 200, self-tapping screws 300, a hanger 400, and a deformable sound-absorbing panel 500. The two ends of the frame 100 are connected to the support member 200 through frame units, and the middle position of the frame 100 can be connected to the hanger 400 through a frame. The shaped contour surface of the frame 100 faces the opposite side to the support member 200, and is used to install the deformable sound-absorbing panel 500. Multiple frames 100 are matched and connected by welding and / or self-tapping screws 300 using a contour line positioning method to form a deformable sound-absorbing panel architectural decorative ceiling structure.

[0045] The border unit includes a first border unit 1 and a second border unit 2.

[0046] Preferably, when the span is greater than 3m, a 400mm hanger is installed, the elevation deviation is ≤2mm, and a two-way nut is preferably installed at the node for locking.

[0047] A construction method for a deformable sound-absorbing panel architectural decorative ceiling structure includes a frame installation stage and a deformable sound-absorbing panel installation stage;

The assembly method includes: full welding at the joint, with a weld leg height ≥3mm, and the non-joint surfaces are connected with self-tapping screws 300 at intervals ≤200mm. Simultaneously, after the second frame 100 is positioned, it is also fixed to the support component 200 of the building transfer floor using J422 welding rods. Due to frame span issues, when the span is >3m, hangers 400 are installed, with an elevation deviation ≤2mm. Two-way nuts are used at the joints for locking, stabilizing the overall shape and ensuring smooth operation.

[0049] After the frame is installed, the deformable sound-absorbing panels 500 are laid. Before laying, silicone structural adhesive is applied after sanding the contact interface of the frame 100. The coating thickness is preferably 1.5±0.2mm. Then, the deformable sound-absorbing panels 500 are bonded and installed with staggered joints, with a long side misalignment of ≥300mm. Before the adhesive strength is sufficient, the deformable sound-absorbing panels 500 are fixed to the frame 100 using self-tapping screws 300. After the silicone structural adhesive has cured, the silicone structural adhesive and the self-tapping screws 300 work together to firmly fix the deformable sound-absorbing panels 500 to the frame, with a flatness of ≤2mm, which facilitates subsequent coating construction.

[0050] This invention achieves a three-dimensional curved surface shape deviation of ≤1.5mm through a dual control system of irregularly shaped surface and positioning groove; the composite fixing of structural adhesive and screws greatly improves the vibration attenuation rate of the sound-absorbing panel; and the C-shaped steel flexible groove design improves the frame forming accuracy to over 99%.
