Description

Technical Field

[0001] The present invention relates to the technical field of curved GRG ceilings, and in particular to a large-span truss-assembled lightweight curved GRG ceiling design structure. Background Art

[0002] GRG is widely used in various types of buildings due to its many advantages such as high strength, strong plasticity, good stability and good flame retardant properties. For example, curved GRG is used as ceiling in large-span truss steel structure buildings such as performing arts theaters, convention and exhibition centers, airport stations, etc. For example, Chinese patent CN117888671A discloses a construction method of a GRG integrated ceiling prefabricated module system, which includes the following steps: S1, panel modularization: S2, construction layout: laying out the measurement control network according to the project main axis control line, and laying out the plane position and elevation of the GRG three-dimensional BIM model into the building; S3, assembling the base steel frame and the secondary transfer layer steel frame: assembling the base steel frame and fixing the base steel frame to the building truss, assembling the secondary transfer layer steel frame according to the layout result and hoisting the secondary transfer layer steel frame to the base steel frame; S4, painting: painting the basic module; S5, assembling the GRG integrated ceiling: splicing and fixing the basic module, functional module and multiple auxiliary modules into GRG ceiling panels, and assembling and splicing multiple GRG ceiling panels into the GRG integrated ceiling, and finally using hoisting equipment to hoist the GRG integrated ceiling to the secondary transfer layer steel frame.

[0003] In the existing curved GRG ceiling, the density of GRG is 1800kg / m 3 , and the finished thickness of the curved GRG modeling components is usually not less than 30mm, which makes its unit area weight much heavier than commonly used lightweight ceiling materials such as gypsum board and aluminum plate. In the large-span truss structure space, due to the large spacing between each truss, excessive load will affect the stability of the truss structure. The ultra-long ceiling hanger spacing and limited lifting points greatly increase the stress on the hanger, which can easily cause deformation, deflection and cracking of the top layer. Summary of the Invention

[0004] The purpose of the present invention is to provide a large-span truss assembled lightweight curved GRG ceiling design structure to solve the problem that the top layer is easily deformed due to the large spacing between each truss of the existing large-span truss structure.

[0005] In order to achieve the above objectives, the present invention adopts the following technical solution: a large-span truss assembled lightweight curved GRG ceiling design structure, comprising:

[0006] truss;

[0007] a transfer layer, which is removably installed below the trusses;

[0008] The mounting assembly includes a base, a mounting arm, a mounting plate and a cross-bracing arm. The base is fixedly mounted on the transfer layer, the mounting arm is rotatably mounted on the base, two back-to-back mounting arms are provided on the base, the mounting plate is a plate body with an arc-shaped cross section, the mounting plate is fixedly mounted on the end of the mounting arm, the mounting plate is clamped on the main beam of the truss, a cross-bracing arm is provided between the two mounting arms, and the cross-bracing arm is parallel to the transfer layer;

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, a detachable conversion layer is provided under the truss.

[0046] Example 1

[0047] See also Figure 1-7 The present invention provides a technical solution: a large-span truss assembled lightweight curved GRG ceiling design structure, comprising:

[0048] Truss 1;

[0049] A transfer layer 2, which is detachably installed below the truss 1;

[0050] The mounting assembly 3 includes a base 31, a mounting arm 32, a mounting plate 33, and a cross-bracing arm 34. The base 31 is fixedly mounted on the transfer layer 2, and the mounting arm 32 is rotatably mounted on the base 31. The base 31 is provided with two back-to-back mounting arms 32. The mounting plate 33 is a plate body with an arc-shaped cross section. The mounting plate 33 is fixedly mounted on the end of the mounting arm 32. The mounting plate 33 is clamped on the main beam 11 of the truss 1. A cross-bracing arm 34 is provided between the two mounting arms 32, and the cross-bracing arm 34 is parallel to the transfer layer 2.

[0051] A hanger 4, the top of which is fixedly mounted on the transfer layer 2;

[0052] The GRG ceiling panel 5 is fixedly mounted on the bottom of the suspension rod 4 .

[0053] A threaded rod 331 is provided on the back of the mounting plate 33, which is threadedly connected to the end of the mounting arm 32. The threaded rod 331 not only effectively compensates for errors in the installation position of the base 31, adjusts the overall length of the mounting arm 32, and ensures that the mounting plate 33 is mounted on the truss, but also allows the angle of the mounting plate 33 to be adjusted, so that the mounting assembly 3 and the mounting arm 32 in different installation positions can match the curvature of the truss 1, achieving an effective connection.

[0054] The connecting arms 32 are provided with connecting sleeves 321, which are mounted on the connecting arms 32. One end of the cross brace arm 34 is rotatably mounted on the connecting sleeve 321 of one connecting arm 32, and the other end is detachably mounted on the connecting sleeve 321 of the other connecting arm 32. After the two connecting arms 32 are connected to the truss 1, the connecting sleeves 321 on the two connecting arms 32 are adjusted to the same height. The cross brace arm 34 is then rotated horizontally so that the end of the cross brace arm 34 is fixed to the connecting sleeve 321 of the other connecting arm 32. Bolts are then passed through the connecting plate at the end of the connecting arm 32 and the connecting plate on the connecting sleeve 321, and then secured with nuts.

[0055] An extension rod 341 is provided at the end of the transverse support arm 34 . The extension rod 341 is threadedly connected to the transverse support arm 34 , and the end of the extension rod 341 is fixedly mounted on the connecting sleeve 321 .

[0056] The cross bracing arm 34 can be adjusted to extend or retract the end of the extension rod 341 by rotating the extension rod 341, and the overall length of the cross bracing arm 34 can be increased or decreased, so that the length of the cross bracing arm 34 can be adjusted to adapt to the spacing between the connecting sleeves 321 on the two hanging arms 32, and the installation height of the cross bracing arm 34 can be flexibly adjusted, thereby further improving the overall deformation resistance of the hanging component 3 and improving the stability of the installation of the conversion layer 2.

[0057] An embedded part 51 is provided on the back of the GRG ceiling panel 5 , and the bottom of the suspension rod 4 is fixedly mounted on the embedded part 51 .

[0058] Two diagonal braces 52 are provided on the embedded component 51, symmetrically arranged on either side of the suspension rod 4. Connecting seats 521 are provided at the ends of the diagonal braces 52, which are threadedly connected to the diagonal braces 52. The connecting seats 521 are fixedly mounted on the transfer layer 2. The diagonal braces 52 are rotatably mounted on the embedded component 51. The connecting seats 521 at the top of the diagonal braces 52 can be rotated to adjust the overall length of the diagonal braces 52. When the diagonal braces 52 are fixed to the transfer layer 2 via the connecting seats 521, the diagonal braces 52 and the suspension rod 4 are arranged at a 45-degree angle, achieving stable reverse support and preventing the lightweight GRG ceiling panels 5 from deforming due to negative wind pressure causing the ceiling to move upward.

[0059] The suspension rod 4 includes an outer tube body 41 and an inner rod body 42. The outer tube body 41 is fixedly mounted on the conversion layer 2, and the inner rod body 42 is threadedly connected to the outer tube body 41. The suspension rod 4 is adjustable in length to facilitate fixation with the conversion layer 2.

[0060] A light trough 6 is provided in the gap between two adjacent GRG ceiling panels 5 .

[0061] The sidewalls of the light trough 6 are bent outward to form spring clips 61, and the edges of the GRG ceiling panels 5 contact the spring clips 61. A gap is provided between the ends of the spring clips 61 and the main body of the light trough 6. The light trough 6 is set in the joint between two adjacent GRG ceiling panels 5, and the spring clips 61 elastically contact the joint, leaving sufficient expansion and contraction distance and space for the light strip installation at the joint, effectively preventing longitudinal deformation and cracking of the ceiling.

[0062] Working Principle: A detachable transfer layer 2 is provided below the truss 1. The transfer layer 2 is fixedly installed between two adjacent truss 1 units with a large spacing via a mounting assembly 3. The rotatable mounting arm 32 on the base 31 is connected to the main beam 11 of the truss 1 via a mounting plate 33, enabling detachable installation while avoiding damage to the truss 1. The two mounting arms 32 are locked by a cross brace 34 to prevent rotation, thereby improving the overall deformation resistance of the mounting assembly 3 and enhancing the installation stability of the transfer layer 2. The addition of the transfer layer 2 to the suspended ceiling facilitates the installation of the hangers, controls the spacing of the hangers, and avoids deformation of the suspended ceiling. At the same time, the transfer layer 2 is connected to the truss 1 through the mounting assembly 3 to achieve a lossless connection, avoiding damage to the structural strength of the truss 1.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
