Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0072] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0073] like Figures 1 to 10 As shown, a hyperbolic roof assembly installation structure 10 provided in an embodiment of the present application includes a mounting seat 1, a first support 3, a second support 4, a connecting member 5, a pressing member 6 and a triangular decorative plate 7;

[0074] The mounting seat 1 is provided with three brackets 2 which are symmetrically distributed with 120 degrees of rotation. The brackets 2 have transverse strip holes 20 arranged in the horizontal direction. The first support 3 has longitudinal strip holes 30 arranged in the vertical direction. The transverse strip holes 20 and the longitudinal strip holes 30 are matched and connected with fastening bolts 31.

[0075] The second support 4 is located on the top of the first support 3, and the second support 4 and the first support 3 have mutually adapted arc-shaped contact surfaces, and the arc-shaped contact surfaces are provided with a first sawtooth groove 40;

[0076] The triangular decorative plate 7 includes a frame formed by three frames 70 and an aluminum single plate 71 laid on the frame. The outer side of the frame 70 is provided with a first plug-in groove 70a. The connector 5 is inserted into the first plug-in groove 70a and connected to the second support 4.

[0077] The pressing member 6 presses the connecting member 5 and connects the second support 4 .

[0078] In this embodiment, the method of replacing circles with polygons is used to set the parallel sides of each triangular decorative panel 7 and the adjacent triangular decorative panels 7 to a smooth transition, and the linear change of the single triangular decorative panel 7 is adjusted according to the elevation of the third corner of the triangular decorative panel 7. The overall special-shaped hyperboloid shape is constructed by the angle change of continuous triangles. During the design, the original BIM model is used as a reference, and the projection surface of the hyperboloid is divided into triangular units according to the principles of axis division and symmetry. The installation nodes of the mounting base 1 are determined according to the intersection points between the triangular units. The GIS model of the roof of a large building obtained by actual surveying is compared and analyzed to determine the specific construction measures for each installation node (i.e., whether the installation node has a concrete surface layer, whether there are special structures such as the gutter 102, etc.).

[0079] Specifically, the mounting seat 1 is used to be installed and fixed on the roof of a large building. During the specific implementation, the specific form of the mounting seat 1 is designed according to the specific situation of the location of the mounting node. For example, when the current mounting node is a concrete surface layer, steel bars are inserted into the concrete surface layer of the mounting node, and then concrete is poured to form a pier 100. The concrete is embedded in the steel bar structure 101 during the hydration heat stage to form the above-mentioned mounting seat 1; if the current mounting node is a special-shaped structure such as a gutter 102, a step or an inner eave, a concrete pier 100 is poured at the side of the gutter 102 according to the construction drawings, and a steel connecting beam 103 is installed after the steel bar structure 101 is embedded to form an upper The above-mentioned mounting seat 1; if the current mounting node has no concrete surface layer, a steel pipe column 105 is welded on the steel beam structure of the roof to form the above-mentioned mounting seat 1. In the present embodiment, three brackets 2 are provided on the mounting seat 1 which are rotationally symmetrically distributed at 120°. Each bracket 2 can be assembled with two triangular decorative panels 7. The elevation of the first bracket 3 (i.e., the height of the first bracket 3) can be adjusted through the longitudinal strip hole 30 according to the actual construction situation to facilitate a smooth transition with the triangular decorative panel 7 on the adjacent mounting seat 1. The horizontal position of the first bracket 3 on the corresponding mounting seat 1 can be adjusted through the transverse strip hole 20 to avoid interference and collision between adjacent triangular decorative panels 7.

[0080] The arc-shaped contact surfaces of the first support 3 and the second support 4 are adapted to each other, and a meshing connection is achieved through the first serrated groove 40 on the arc-shaped contact surface, ensuring that the second support 4 can be rotated and adjusted within a preset angle range of 0° to 45°. After the first support 3 is fixed to the bracket 2 by bolts, the rotation angle of the second support 4 can be adjusted according to the preset parameters of the construction drawing, so that the triangular decorative panel 7 can achieve curved surface transitions at multiple angles.

[0081] In this embodiment, by adjusting the elevation and horizontal position of the first support 3 and the angle of the second support 4, it is ensured that the aluminum plate can be optimized into a flat-plate fitting surface. The top of the second support 4 is the mounting surface of the triangular decorative plate 7. The second support 4 is provided with two mounting surfaces. The two mounting surfaces can be located on the same horizontal plane or can intersect. When intersecting, a more complex flat-plate fitting surface can be constructed. After installing the first support 3 and the second support 4, the connector 5 is inserted into the first insertion slot 70a of the aluminum frame 70, and then the connector 5 is fixed to one side of the second support 4 by screws. The second aluminum frame 70 is installed in the same way, and the connector 5 is pressed by the clamping member 6 to improve the overall strength of the triangular decorative plate 7. By way of example, the side length of the triangular decorative plate 7 is 4m.

[0082] Compared with the prior art, the hyperbolic roof assembly installation structure 10 provided in the present application has three rotationally symmetrically distributed brackets 2 on the mounting seat 1. The brackets 2 cooperate with the first support 3, and can adjust the horizontal position of the triangular decorative plate 7 through the transverse strip hole 20 to avoid collision of the special-shaped hyperbolic surface, and adjust the elevation of the triangular decorative plate 7 through the longitudinal strip hole 30 to control the parameter error that occurs in the actual installation. The first support 3 and the second support 4 are provided with mutually adapted arc-shaped contact surfaces, which can adjust the inclination angle of the triangular decorative plate 7 to ensure that the adjacent triangular decorative plates 7 can optimize the flat fitting surface. The mounting seat 1 of the hyperbolic roof assembly installation structure 10 can install six triangular decorative plates 7, and the triangular decorative plates 7 on each bracket 2 will not interfere with or collide with each other. Different special-shaped surfaces can be fitted on one mounting seat 1, thereby constructing a large-span hyperbolic structure based on triangles.

[0083] In a preferred embodiment, the first support 3 comprises two symmetrically arranged plates 32 provided with longitudinal strip holes 30, the bracket 2 is located between the two plates 32, an arc-shaped plate 33 is provided on the top of the plate 32, and one end face of the arc-shaped plate 33 away from the plate 32 is an arc-shaped contact face, and the first serrated grooves 40 are evenly distributed on the arc-shaped contact face along the axial direction of the arc-shaped plate 33.

[0084] The first support 3 and the second support 4 are both made of aluminum. The bracket 2 is inserted into the first support 3. The two plates 32 are locked by bolts to clamp the fixed bracket 2. The first serrated groove 40 arranged on the arc plate 33 can provide static friction for the second support 4 to ensure that the bolts can still be locked when they are loose, thereby reducing the maintenance times of the hyperbolic roof. The height range of each sawtooth in the first serrated groove 40 is 1 to 3 mm, and the tooth width is 1 to 3 mm. The larger the sawtooth height and tooth width of the first serrated groove 40, the larger the angle range that the second support 4 can adjust. For example, when the sawtooth height is 1 mm and the sawtooth width is 1 mm, the angle value of the second support 4 for a single adjustment is 0.5°.

[0085] In a preferred embodiment, a reinforcing plate 34 is provided on the outer wall of the plate body 32, and second serrated grooves 34a that match each other are provided on the reinforcing plate 34 and the plate body 32, and the second serrated grooves 34a are equidistantly distributed along the height direction of the plate body 32. Under this arrangement, the fastening performance of the first support 3 and the bolts can be improved, ensuring that the second support 4 can still be fastened to the bracket 2 after the bolts are loosened, thereby preventing the first support 3 from slipping and causing structural damage to the entire hyperbolic roof.

[0086] In a preferred embodiment, the connector 5 is provided with a second insertion groove 50 on one end surface facing the second support 4, and a sealing strip 51 is inserted into the second insertion groove 50. Specifically, the connector 5 is made of aluminum alloy, and the sealing strip 51 between the connector 5 and the second support 4 can avoid extrusion wear between the connector 5 and the second support 4 through the elasticity of the sealing strip 51, thereby offsetting the deformation stress of the two.

[0087] In order to prevent potential corrosion between the first support 3 and the bracket 2 , a rubber pad is further provided on the outer side of the bracket 2 .

[0088] In a preferred embodiment, the bracket 2 includes a steel plate 21 and a steel rib plate 22. The steel plate 21 is vertically arranged on the mounting seat 1, and the steel rib plate 22 connects the steel plate 21 and the mounting seat 1 respectively.

[0089] In a preferred embodiment, the triangular decorative plate 7 further includes a reinforcing structure, and adjacent frames 70 are connected and fixed by the reinforcing structure, and the reinforcing structure includes aluminum tubes 72 and groove aluminum 73, and the aluminum tubes 72 and groove aluminum 73 are crisscrossed.

[0090] In a preferred embodiment, see Figures 11 to 16 , and combined with Fig.17 The aluminum single plate 71 is provided with a triangular hollow structure.

[0091] In a preferred embodiment, the ends of the adjacent frames 70 are connected at an angle via angle aluminum 74 .

[0092] In a preferred embodiment, the surface of the above-mentioned aluminum single plate 71 is coated with a fluorocarbon layer, and the surfaces of the first support 3, the second support 4, the connecting piece 5, the clamping piece 6, the angle aluminum 74, the frame 70, the aluminum tube 72 and the groove aluminum 73 are all provided with an anodized layer.
