Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a glass roofing system with a space grid shell. Background Technology

[0002] In the history of architectural development, traditional roofs such as concrete flat roofs and pitched roofs, although widely used, have many shortcomings. Concrete flat roofs are prone to leakage, are susceptible to long-term rainwater erosion, and have high maintenance costs after the waterproofing layer ages; moreover, their thermal insulation performance is limited, requiring a lot of energy for cooling in summer and providing poor insulation in winter.

[0003] With societal development, building functions are becoming increasingly diversified. Public buildings such as stadiums, exhibition halls, and airport terminals are placing higher demands on roof span, lighting effects, and aesthetic presentation. Large-span roofs can provide open, column-free interior spaces, meeting the needs of large-scale events and exhibitions; good lighting introduces natural light, reducing indoor lighting energy consumption and creating a comfortable indoor environment; unique designs become urban landmarks, showcasing the building's cultural connotations and artistic value. Traditional roofs struggle to simultaneously address these characteristics, prompting the construction industry to explore new roofing systems. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a glass roofing system with a spatial mesh shell. This system has a simple and ingenious structure, modular design, and is convenient and quick to assemble and construct.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a space grid shell glass roof system, including multiple splicing units, which are spliced ​​together to form a spherical grid shell structure. Each splicing unit is triangular, and the edges of adjacent splicing units abut each other. The abutting splicing units are fixedly connected by bolt and nut assemblies. Each splicing unit has a triangular glass panel fixedly bonded to it with curtain wall adhesive. The gaps between adjacent glass panels are filled with structural adhesive for sealing.

[0006] Each of the splicing units includes a support frame formed by three irregularly shaped tubes joined end to end. Each of the irregularly shaped tubes is machined with a connecting hole that penetrates its inner and outer facades. The bolt and nut assembly is inserted into the corresponding connecting holes on the adjacent support frames. The glass panel is fixedly bonded to the glass bearing surface of the support frame with curtain wall adhesive.

[0007] The outer facade of the support frame forms an acute angle with the glass bearing surface installation area.

[0008] The splicing unit also includes a support strip, which is clamped between two adjacent support frames. The support strip is a straight triangular prism, and its two adjacent sides are respectively attached to the outer facades of the two support frames.

[0009] The cross-sectional shape of the support strip is set as an isosceles trapezoid, and the edge where the apex of the support strip is located is inserted between two adjacent support frames. The two sides of the support strip abut against the outer facade of the two support frames.

[0010] Each of the splicing units includes three frame connecting rods, three node plates, and multiple glass fixing pins. The three node plates are arranged in a triangular layout, and a frame connecting rod is installed between every two adjacent node plates. Both ends of each frame connecting rod are fixedly connected to the corresponding node plate by bolt and nut assemblies. Multiple glass fixing supports can be detachably and fixedly installed on each node plate. Each glass fixing support has a pin hole on its upper surface. Curtain wall adhesive is applied to the glass bearing surface of the frame connecting rod. The glass panel is placed on the glass bearing surface of the frame connecting rod, and the corner of the glass panel is placed on the glass fixing support. The glass fixing pin passes through the glass panel and is fixedly inserted into the pin hole of the glass fixing support.

[0011] The lower end face of each glass fixing support is fixedly mounted on the node plate by screws, and the pin of each glass fixing pin is threaded, and the glass fixing pin passes through the through hole and is screwed into the pin hole of the glass fixing support.

[0012] Each of the glass fixing pins is fitted with two rubber washers. The two rubber washers are respectively installed between the end of the glass fixing pin and the glass panel and between the glass panel and the glass fixing support. The rubber washers tightly fill the gaps between the glass fixing pin, the glass panel and the glass fixing support.

[0013] A T-shaped adhesive strip is installed at the seam between every two adjacent glass panels, and structural adhesive is applied to the joint between the T-shaped adhesive strip and the glass panel for sealing.

[0014] The beneficial effects of this utility model are as follows: The system is modular, making assembly and construction convenient, enabling rapid construction and high efficiency; the support frames of the splicing units are made of special-shaped tubes, and the spliced ​​support frames can naturally form an angle, facilitating the rapid construction of arched buildings; the combination of support frames and bracing strips in the splicing units allows for flexible adjustment of the arch curvature of the building to meet the needs of structural strength and design; glass fixing supports are set on the node plates of the splicing units, along with glass fixing pins, and positioning holes are opened on the glass panels.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] A spatial grid shell glass roof system includes multiple splicing units 1, which are spliced ​​together to form a spherical grid shell structure. Each splicing unit 1 is triangular, and the edges of adjacent splicing units 1 abut against each other. The abutting splicing units 1 are fixedly connected by bolt and nut assemblies 5. Each splicing unit 1 has a triangular glass panel 4 fixedly bonded to it by curtain wall adhesive 3. The gaps between adjacent glass panels 4 are sealed with structural adhesive 6. The curtain wall adhesive 3 is EPDM special curtain wall adhesive, which has high strength and stable adhesion.

[0026] Each of the splicing units 1 includes a support frame 2 formed by three irregular tubes 21 joined end to end. Each irregular tube 21 is machined with a connecting hole that passes through its inner and outer facades. The bolt and nut assembly 5 is inserted into the corresponding connecting holes on the adjacent support frames 2. The glass panel 4 is fixedly bonded to the glass bearing surface of the support frame 2 by curtain wall adhesive 3.

[0027] The outer facade of the support frame 2 and the glass bearing surface are installed at an acute angle, so that when multiple adjacent support frames 2 are spliced ​​together, the glass bearing surfaces of the multiple support frames 2 will be spliced ​​together to form an arch.

[0028] The splicing unit 1 also includes a support strip 22, which is clamped between two adjacent support frames 2. The support strip 22 is a straight triangular prism, and two adjacent sides of the support strip 22 are respectively attached to the outer side surfaces of the two support frames 2. The support strip 22 has through holes for connecting with the bolt and nut assembly 5.

[0029] The cross-sectional shape of the support strip 22 is set as an isosceles trapezoid. The edge where the apex of the support strip 22 is located is inserted between two adjacent support frames 2. The two sides of the support strip 22 are attached to the outer facade of the two support frames 2. The value of the apex of the support strip 22 can be flexibly set according to the installation needs. That is, the apex of the support strip 22 can be set to multiple values ​​to help adjust the arc of the arch formed by the glass bearing surface of the spliced ​​support frames 2.

[0030] Each splicing unit 1 includes three frame connecting rods 7, three node plates 8, and multiple glass fixing pins 9. The three node plates 8 are arranged in a triangular layout. A frame connecting rod 7 is installed between every two adjacent node plates 8. Both ends of each frame connecting rod 7 are fixedly connected to the corresponding node plate 8 by bolt and nut assembly 5. Multiple glass fixing supports 81 can be detachably and fixedly installed on each node plate 8. Pin holes are opened on the upper surface of each glass fixing support 81. Curtain wall adhesive 3 is applied to the glass bearing surface of the frame connecting rod 7. The glass panel 4 is placed on the glass bearing surface of the frame connecting rod 7. The corner of the glass panel 4 is placed on the glass fixing support 81. The glass fixing pins 9 pass through the glass panel 4 and are fixedly inserted into the pin holes of the glass fixing support 81, thus completing the installation of the glass panel 4 on the splicing unit 1.

[0031] The lower end face of each glass fixing support 81 is fixedly installed on the node plate 8 by screws 82. Each glass fixing pin 9 has threads machined on its pin rod. The glass fixing pin 9 passes through the through hole and is screwed into the pin hole of the glass fixing support 81 to realize the positioning and installation of the glass panel 4 on the splicing unit 1.

[0032] Each of the glass fixing pins 9 is fitted with two rubber washers 83. The two rubber washers 83 are respectively installed between the end of the glass fixing pin 9 and the glass panel 4 and between the glass panel 4 and the glass fixing support 81. The rubber washers 83 tightly fill the gaps between the glass fixing pin 9, the glass panel 4 and the glass fixing support 81.

[0033] A T-shaped adhesive strip 61 is installed at the seam between every two adjacent glass panels 4, and structural adhesive 6 is applied to the seam where the T-shaped adhesive strip 61 mates with the glass panel 4 for sealing.

[0034] The glass panel 4 can be made of single-layer glass, insulated glass, laminated glass, etc., or it can be replaced with a plate structure of other materials, such as metal plate, acrylic plate, etc., according to the construction needs.

[0035] Working principle: The system is set with two types of splicing units 1, so there are two assembly methods.

[0036] In the first method, when using support frames 2 for splicing, multiple support frames 2 are combined and arranged, and the abutting support frames 2 are fixedly connected by bolt and nut assembly 5. Then, curtain wall adhesive 3 is applied to the glass bearing surface of the support frame 2, and finally the glass panels 4 are aligned and bonded. After the glass panels 4 are bonded, structural adhesive 6 is applied to the gaps of each glass panel 4 for sealing treatment, thus completing the system assembly and construction.

[0037] Because the system is arched as a whole, there may be a difference in the curvature between the top and the bottom of the arch, that is, there is a difference in the included angle between the two spliced ​​support frames 2. Therefore, a bracing strip 22 is set. When the included angle of the spliced ​​support frames 2 cannot meet the working conditions, a bracing strip 22 with a matching top angle value is selected and filled between the two adjacent support frames 2. Then, the bolt and nut assembly 5 is used for fixed connection to meet the construction requirements.

[0038] In the second configuration, when using the frame connecting rod 7 and node plate 8 for splicing, the frame connecting rod 7 and node plate 8 are pre-assembled into a triangular splicing unit 1. Then, the splicing unit 1 is assembled into an arch shape. The frame connecting rod 7 and node plate 8 are fixedly connected by bolt and nut assembly 5. After the assembly is completed, curtain wall adhesive 3 is applied to the frame connecting rod 7. Then, the glass panel 4 is aligned and placed on the splicing unit 1. The node plate 8 is pre-installed with glass fixing brackets 81 by screws 82. The rubber gaskets 83 and glass fixing pins 9 are combined and inserted into the glass panel 4. Then, the glass panel 4 is aligned and installed on the splicing unit 1. The I-shaped adhesive strips 61 are clipped into the gaps of the glass panel 4. Finally, structural adhesive 6 is applied to the edges of each I-shaped adhesive strip 61 for sealing.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
