Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and in particular to suspended ceilings, specifically a prefabricated moisture-proof and sound-absorbing suspended ceiling. Background Technology

[0002] Traditional ceiling construction techniques are complex and time-consuming, especially for public venues with special requirements, such as swimming pools, which are often surrounded by residential buildings. These venues not only require convenient construction, easy disassembly and maintenance, and good sound absorption, but also must be fog-proof, moisture-proof, and aesthetically pleasing. Therefore, higher demands are placed on construction difficulty, efficiency, shape precision, overall structure, and sound absorption and moisture-proofing effects. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated moisture-proof and sound-absorbing ceiling for use in swimming pools and other similar venues. This ceiling is moisture-proof, corrosion-resistant, has good sound absorption, strong overall structural integrity, and is easy to install. This utility model achieves its purpose through the following technical solutions.

[0004] A prefabricated moisture-proof and sound-absorbing ceiling includes three or more arc-shaped sound absorbers arranged horizontally. Each arc-shaped sound absorber has straight sides and a curved surface in the middle. The straight sides of the arc-shaped sound absorbers are of the same length and are arranged in parallel alignment. Each arc-shaped sound absorber is connected to a top beam or floor slab via stainless steel hangers. The arc-shaped sound absorbers include three types: an upwardly concave sound absorber, a first downwardly convex sound absorber, and a second downwardly convex sound absorber. Each upwardly concave sound absorber is adjacent to a first downwardly convex sound absorber and a second downwardly convex sound absorber on both sides, forming an overall wave shape. Each arc-shaped sound absorber includes sound-absorbing cotton, a moisture-proof cloth, and an aluminum plate. The moisture-proof cloth wraps around the sound-absorbing cotton to form a sound-absorbing core. The aluminum plate covers the lower surface and sides of the sound-absorbing core and is turned up to cover the edge of the upper surface of the sound-absorbing core.

[0005] Further optimization involves the upper concave sound absorber and the first lower convex sound absorber having the same arc length and inner diameter. The arc length of the first lower convex sound absorber is greater than that of the second lower convex sound absorber, and the inner diameter of the first lower convex sound absorber is greater than that of the second lower convex sound absorber. An equal-width gap is provided between two adjacent arc-shaped sound absorbers.

[0006] Furthermore, the length of the arc of the concave sound absorber and the first convex sound absorber is 2300~2600mm, and the inner diameter of the arc is 1700~1900mm. The length of the arc of the second convex sound absorber is 1200~1300mm, and the inner diameter of the arc is 650~750mm. The gap width between two adjacent arc-shaped sound absorbers is 85~95mm.

[0007] Furthermore, the arc-shaped sound absorber has the same thickness, which is 98~102mm; the aluminum plate has a thickness of 2mm, and the turning edge width of the aluminum plate in the upturned part is 10cm; the aluminum plate in the upturned part is provided with punched holes, and embedded fixing bolts are provided in the punched holes.

[0008] Furthermore, the stainless steel lifting component is a stainless steel lifting thread rod.

[0009] Furthermore, the stainless steel suspension component includes: a telescopic suspension rod, a stainless steel U-shaped support connected to the upper part of the telescopic suspension rod, and a connector connected to the lower part of the telescopic suspension rod. The stainless steel U-shaped support is provided with bolt holes for connection with stainless steel expanded-bottom anchor bolts on the top beam or floor slab. The connector is connected to a stainless steel fastener. The stainless steel fastener includes a horizontal connecting plate and inclined plates provided on both sides of the horizontal connecting plate. The inclined plates on both sides are respectively connected to the straight edges on both sides of the arc-shaped sound absorber.

[0010] Furthermore, aluminum plate reinforcing ribs are provided on both straight sides of the arc-shaped sound absorber, and the lower end of the inclined plate is rolled up around the outer diameter of the aluminum plate reinforcing ribs and fixed.

[0011] Furthermore, a perforated aluminum panel, secured by stainless steel vertical hooks, is installed on the outer side of the outermost arc-shaped sound absorber. A custom-designed multi-functional integrated strip is installed on the upper side of the perforated aluminum panel.

[0012] The advantages and beneficial effects of this utility model are:

[0013] 1) The curved sound-absorbing body structure of this utility model ceiling has excellent acoustic diffusion and sound absorption effects, achieving good sound absorption and diffusion, and avoiding the phenomenon of non-diffusion or uneven sound. The individual curved sound-absorbing bodies in its wave-shaped whole are similar to grids, which can achieve effective sound diffusion, while the gaps between the sound-absorbing bodies and the sound-absorbing cotton structure can achieve sound absorption.

[0014] 2) The prefabricated wave-shaped sound-absorbing ceiling of this utility model has good weather resistance, corrosion resistance, oxidation resistance and strong moisture resistance.

[0015] 3) The arc-shaped structure of the arc-shaped sound absorber and the surface of the aluminum plate make it unfavorable for water mist condensation.

[0016] 4) The prefabricated wave-shaped sound-absorbing ceiling of this utility model is easy to construct and level, which helps to improve construction efficiency. Attached Figure Description

[0025] Example 1

[0026] like Figures 1-3 As shown, a prefabricated moisture-proof and sound-absorbing ceiling includes 11 horizontally arranged arc-shaped sound absorbers 1. Each arc-shaped sound absorber 1 has straight sides and a curved center. The straight sides of each arc-shaped sound absorber 1 are of equal length and are arranged in parallel alignment. A gap of equal width is provided between adjacent arc-shaped sound absorbers 1. Each arc-shaped sound absorber 1 is connected to a top beam or floor slab via a stainless steel hanger 3. A perforated aluminum panel 8, fixed by a stainless steel vertical hanger 7, is located on the outermost arc-shaped sound absorber 1. A customized multi-functional integrated strip 9 is located on the upper side of the perforated aluminum panel 8.

[0027] like Figure 2As shown, the arc-shaped sound absorber 1 includes three types: an upper concave sound absorber 11, a first lower convex sound absorber 12, and a second lower convex sound absorber 13. Each upper concave sound absorber 11 is adjacent to a first lower convex sound absorber 12 and a second lower convex sound absorber 13 on both sides, thus forming an overall wave shape. The arc length of the upper concave sound absorber 11 and the first lower convex sound absorber 12 is 2508mm, and the inner diameter of the arc is 1800mm. The arc length of the second lower convex sound absorber 13 is 1283mm, and the inner diameter of the arc is 700mm. The gap width between two adjacent arc-shaped sound absorbers is 90mm.

[0028] The arc-shaped sound absorbers 1 are all of uniform thickness. Each arc-shaped sound absorber 1 includes sound-absorbing cotton 101, a moisture-proof cloth 102, and an aluminum plate 103. The moisture-proof cloth 102 wraps around the sound-absorbing cotton 101 to form a sound-absorbing core. The aluminum plate 103 covers the lower surface, both sides, and the edge of the upper surface of the sound-absorbing core. The upper part of the aluminum plate 103 has perforations, and embedded stainless steel bolts 5 are installed in the perforations. The thickness of the arc-shaped sound absorber 1 is 100mm; the thickness of the aluminum plate 103 is 2mm, and the width of the turned edge of the upper part of the aluminum plate 103 is 10cm.

[0029] In this embodiment, the stainless steel hanger 3 is a stainless steel lifting thread rod. The stainless steel lifting thread rod is connected to the stainless steel expanded-base anchor bolts 4 installed on the floor slab or roof beam. The stainless steel lifting thread rod and the stainless steel expanded-base anchor bolts can be connected by a connecting plate or as a single integral component.

[0030] Example 2

[0031] This embodiment is an improvement upon embodiment 1. The stainless steel lifting component 3 has been modified.

[0032] like Figure 4 , 5 As shown, the stainless steel suspension component 3 includes: a telescopic suspension rod 31, a stainless steel U-shaped support 32 connected to the upper part of the telescopic suspension rod 31, and a connector 33 connected to the lower part of the telescopic suspension rod 31. The stainless steel U-shaped support 32 is provided with bolt holes for connection with the stainless steel expanded-bottom anchor bolts 4 of the top beam. The connector 33 is connected to a stainless steel fastener 2. The stainless steel fastener 2 includes a horizontal connecting plate 201 and inclined plates 202 provided on both sides of the horizontal connecting plate. The inclined plates 202 on both sides are respectively connected to the straight edges on both sides of the arc-shaped sound absorber 1. The straight edges on both sides of the arc-shaped sound absorber 1 are provided with aluminum plate reinforcing ribs 104. The lower end of the inclined plate 202 is rolled up around the outer diameter of the aluminum plate reinforcing rib 104 and fixed. The connector 33 is welded, snap-fitted, or integrally formed with the telescopic suspension rod 31. The connector 33 is provided with through holes and is connected to the stainless steel fastener 2 by stainless steel bolts; or the connector 33 and the stainless steel fastener 2 are connected by snap-fit.

[0033] After improvements, the number of hanging parts on each curved sound absorber can be reduced from four to two, making installation more convenient, allowing for a wider range of height adjustment, and greatly reducing the use of small parts such as bolts.

[0034] Finally, it should be noted that the above is only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model.
