Description

Technical Field

[0001] The invention belongs to the technical field of foamed ceramic installation, and in particular relates to a ceiling assembly method of special-shaped foamed ceramics. Background Art

[0002] In the field of construction, foamed ceramics, as a new type of material, are widely used in various decoration and structural engineering due to their unique structure and performance. Compared with traditional ceramics, foamed ceramics have more complex shapes and diversified sizes, which can meet the needs of different construction projects. The shape of foamed ceramics can be flat or concave and convex, regular or irregular, and the thickness can also be adjusted according to design requirements. For example, the foamed ceramics in the shape of rockery not only have irregular shapes with ups and downs, but also have greater thickness in some areas.

[0003] However, the assembly and industrial production of foamed ceramics have not yet been realized in the prior art, resulting in the construction process being highly dependent on the technical level of on-site workers, which in turn affects the stability of the project quality. At present, the installation of foamed ceramics mainly adopts the process of structural adhesive plus anchor bolts, and its specific steps include: using structural adhesive to bond the steel frame and the foamed ceramics, and then using anchor bolts to fix the foamed ceramics after the structural adhesive is bonded, and it is necessary to manually open anchor bolt holes on the foamed ceramics on site. This method has the following main problems: 1. Time-consuming and labor-consuming: The process of manual hole opening and anchor bolt fixing is cumbersome, and rapid assembly cannot be achieved, resulting in low construction efficiency; 2. Unstable project quality: The construction quality is limited by the workers' installation technical level, and the construction results of different workers may vary greatly; 3. Adaptability issues: Due to the variable shape of foamed ceramics, conventional hanging keel systems are difficult to adapt to their installation requirements, especially when the foamed ceramics are designed to have a large thickness and irregular shape.

[0004] In addition, in the prior art, due to the high-altitude construction work, the installation difficulty of foamed ceramics at the top floor is much greater than that at the wall, which is mainly attributed to the following points: first, in order to reach the installation location, workers usually need to rely on auxiliary equipment such as scaffolding or lifting platforms; second, due to stability and safety issues, workers must take additional safety measures, such as wearing safety belts, and ensuring that all tools and materials are securely fixed to prevent falling; third, physical fatigue increases, and workers work at unusual angles and postures, which not only increases the physical burden, but may also affect work efficiency and accuracy due to fatigue, while limited vision and insufficient ventilation and lighting further increase the difficulty of construction, especially when precise alignment and installation are required; in addition, the limitation of construction space also affects the operating range and mobility of workers, and the complexity of the technical requirements for the specific fixing method of foamed ceramic materials makes the operation at the top floor more complicated; finally, the difficulty of maintenance and repair should not be ignored. Once the installation is completed, the subsequent maintenance and repair of the foamed ceramics on the ceiling will face similar challenges as during installation. These factors together constitute the technical obstacles faced by foamed ceramics during the installation of the ceiling. Summary of the invention

[0005] In order to solve the problems existing in the prior art mentioned above, the purpose of the present invention is to provide a method for assembling a suspended ceiling of special-shaped foamed ceramics, which can realize accurate layout of embedded bolts through software calculation, and can adapt to panels of different shapes and sizes through dry hanging connection of keyholes and embedded bolts, thereby improving installation accuracy and reliability, improving construction efficiency and reducing time and labor costs; in addition, customized installation of the suspended ceiling keel system is provided according to the different weights of the foamed ceramics, thereby enhancing firmness.

[0046] In order to better understand the purpose, structure and function of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] In the description of the present invention, it should be noted that the positional relationships indicated by terms such as “longitudinal”, “lateral”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” etc. cited in this specification are based on the positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0048] This embodiment provides a method for assembling a suspended ceiling of a special-shaped foamed ceramic 1, comprising the following steps:

[0049] S1, such as Figures 1 to 3 As shown, embedded bolts 11 are arranged on the back side of the foamed ceramic 1 .

[0050] S1-1. Determine the shape and thickness of the foamed ceramic 1 according to the design requirements and site requirements of the specific project.

[0051] S1-2. Use modeling software to digitally layout the foamed ceramic 1, and combine it with the panel connection structure calculation method to determine the position and number of embedded bolts 11 on the foamed ceramic 1 by building layout and calculation to adapt to the installation force of foamed ceramics 1 of different shapes and thicknesses, thereby improving the stability when assembling and fixing special-shaped foamed ceramics 1.

[0052] The modeling software is Revit or Rhino modeling software; the panel connection structure calculation method is a conventional force structure analysis method, which is not described here. Since the shape design of the foamed ceramic 1 is different in different construction projects, the number of embedded bolts 11 on the foamed ceramic 1 board and the spacing between the embedded bolts 11 in different projects are different.

[0053] S1-3, according to the position and number of the embedded bolts 11, the embedded bolts 11 are arranged on the back side of the foamed ceramic 1, and the three-nut structure 12 is threadedly fixed on the top of the embedded bolts 11, which avoids the problem of easy disengagement of the conventional single nut and improves the firmness of the foamed ceramic 1 after dry hanging construction on the top surface. Figure 3 As shown, the three-nut structure 12 includes a first nut, a second nut and a third nut arranged in sequence from the outside to the inside on the embedded bolt 11, and a gap is provided between the second nut and the third nut for dry hanging during subsequent rapid assembly and disassembly.

[0054] S2. Determine and prefabricate a ceiling keel system with dry hanging holes 53 according to the weight of the foamed ceramic 1, and install the ceiling keel system on the top floor 4. The weight of the foamed ceramic 1 is determined by comparing it with the weight of a 9.5 mm thick double-layer gypsum board: when the weight per unit area of ​​the foamed ceramic 1 is less than the weight of the 9.5 mm thick double-layer gypsum board, the foamed ceramic 1 is determined to be lighter; when the weight per unit area of ​​the foamed ceramic 1 is greater than the weight of the 9.5 mm thick double-layer gypsum board, the foamed ceramic 1 is determined to be heavier.

[0055] When the foamed ceramic 1 is light in weight, such as Figure 4 and Figure 5 As shown, the ceiling keel system includes a U-shaped light steel keel 71 and a through-thread hanger 72. Through force calculation, it can be known that the strength of the ceiling keel system composed of the through-thread hanger 72 and the U-shaped light steel keel 71 can meet the load-bearing requirements of the foamed ceramic 1. The front of the U-shaped light steel keel 71 is provided with a dry hanging hole 53 and a hanging rod hole 54. The through-thread hanger 72 is vertically fixed to the U-shaped light steel keel 71 through the hanging rod hole 54. The through-thread hanger 72 is threadedly connected to the hanging rod hole 54, and the dry hanging hole 53 is in the shape of a dry hanging hole 53.

[0056] When the foamed ceramic 1 is heavy, it can be known from the force calculation that the strength of the ceiling keel system composed of the through-wire hanger rod 72 and the U-shaped light steel keel 71 cannot meet the load-bearing requirements of the foamed ceramic 1. Figure 6As shown, the ceiling keel system includes a steel keel 81 and a positioning angle code 82. The steel keel 81 includes a horizontal section and a vertical section that are perpendicular to each other. The vertical section is welded and fixed to the horizontal section. The horizontal section uses a square steel pipe, and the vertical section uses an angle steel. The specifications of the square steel pipe and the angle steel are both 50*50*5mm, and both are made of galvanized material. A dry hanging hole 53 is provided on the lower end surface of the horizontal section, and the dry hanging hole 53 is in the shape of a dry hanging hole 53. The position of the dry hanging hole 53 is determined according to the position and spacing of the embedded bolts 11 in step S1. The punching process of the steel keel 81 can be completed in advance in the factory so that the opening position of the dry hanging hole 53 corresponds to the position of the embedded bolts 11; a hanging rod hole 54 is provided on the vertical section, and the hanging rod hole 54 is located at a position near the upper end of the side surface of the vertical section. The opening position of the hanging rod hole 54 is determined according to the design requirements of different projects combined with the calculation of the ceiling connection structure. Positioning holes for fixed connection with the top floor slab 4 and vertical waist-shaped holes for fixed connection with the hanging rod holes 54 are respectively provided on the side panels on both sides of the positioning angle code 82.

[0057] The assembly setting of the foamed ceramic 1 can be achieved by punching holes in the U-shaped light steel keel 71 or the steel keel 81, avoiding the use of electric welding, improving safety and construction efficiency, and having flexible adjustability, which can be suitable for load-bearing installation of foamed ceramics 1 under different weight conditions.

[0061] S2-3. Adjust the installation position of the ceiling keel system: adjust the length of the threaded hanger 72 through the hanger hole 54, and then adjust the distance between the U-shaped light steel keel 71 and the top floor 4 and the horizontality of the U-shaped light steel keel 71, so as to effectively deal with the uneven top floor 4.

[0062] (2) In Example 2, when the foamed ceramic 1 is heavy, the specific steps of prefabricating and installing the ceiling keel system include:

[0064] S2-2, installation of ceiling keel system: positioning on the top floor 4 according to the installation position of each steel keel 81, vertically hoisting the steel keel 81 to the lower end of the top floor 4 through the positioning angle code 82, specifically, fixing the positioning hole of the positioning angle code 82 to the lower end surface of the top floor 4 through fasteners, and fastening the vertical waist hole of the positioning angle code 82 to the hanging rod hole 54, fixing the positioning hole to the top floor 4 with expansion bolts 43, and fixing the vertical waist hole to the hanging rod hole 54 with bolt assemblies.

[0065] S2-3. Adjust the installation position of the ceiling keel system: by positioning the vertical waist-shaped holes on the angle code 82, adjust the distance between the steel keel 81 and the top floor 4 and the horizontality of the steel keel 81, so as to effectively deal with the uneven top floor 4.

In actual work, when the surface of the foamed ceramic 1 is dirty or damaged, it can be easily cleaned and replaced by disassembling.
