Description

Technical Field

[0001] This invention relates to the field of steel structure membrane cladding installation, and particularly to a steel structure membrane cladding installation structure and installation method. Background Technology

[0002] Membrane structures are the most representative architectural form of the 21st century, with high technical content. In particular, PTFE membrane structures have beautiful, simple, and bright curved shapes, which are a perfect combination of rigidity and flexibility, strength and beauty. When combined with night lighting, they are dazzling and colorful, with a strong visual effect.

[0003] However, existing membrane structures mostly adopt the inverted membrane construction technology, which involves many irregularly shaped membrane locking nodes and a long construction period. This makes it impossible to guarantee the quality and efficiency of on-site installation. Alternatively, due to the complexity of the membrane locking nodes, limited operating space, and high requirements for material processing precision, the expected architectural completion effect cannot be achieved. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a steel structure membrane cladding installation structure and method. By utilizing an installation node structure that combines a double-helix arc tube with a membrane locking plate, the problems of numerous membrane cladding tensioning points and long construction periods are solved.

[0005] This invention is achieved through the following solution: a steel structure membrane cladding installation structure, comprising:

[0006] Multiple locking film panels are arranged outside the steel structure and connected to the film veneer. The inner surface of the locking film panel is connected to a first connector for supporting the locking film panel outside the steel structure and forming a first through space between the locking film panel and the steel structure. The outer surface of the locking film panel is connected to a second connector for supporting the decorative components outside the steel structure outside the locking film panel and forming a second through space between the decorative components and the locking film panel.

[0007] A double-helix arc tube is spirally arranged around the steel structure. The double-helix arc tube includes an inner arc tube that passes through the first through space and is supported on the inner surface of the membrane surface, and an outer arc tube that passes through the second through space and is pressed against the outer surface of the membrane surface.

[0008] A further improvement of the steel structure membrane cladding installation structure of the present invention is that the steel structure is cocoon-shaped, including a top circular tube, a bottom circular tube, and multiple radial arched main rods that are circumferentially spaced between the top circular tube and the bottom circular tube and are connected by the first connecting member; the decorative component includes multiple radial decorative strips; multiple locking membrane plates, multiple radial decorative strips, and multiple radial arched main rods are arranged in a one-to-one correspondence.

[0009] A further improvement of the steel structure membrane cladding installation structure of the present invention is that the membrane cladding includes multiple membrane blocks for covering each of the two adjacent radial arched main rods, the first connector and the second connector are both connected to the middle position of the locking plate, and the two sides of the locking plate form locking edges for the overlapping of two adjacent membrane blocks.

[0010] A further improvement of the steel structure membrane cladding installation structure of the present invention is that: the first connecting member includes a plurality of first connecting rods spaced apart along the length direction of the locking membrane plate, the plurality of first connecting rods dividing the first penetration space into a plurality of first compartments through which the inner arc tube selectively passes; the second connecting member includes a plurality of second connecting rods spaced apart along the length direction of the locking membrane plate, the plurality of second connecting rods dividing the second penetration space into a plurality of second compartments through which the outer arc tube selectively passes.

[0011] A further improvement of the steel structure membrane cladding installation structure of the present invention is that the multiple first connecting rods of the first connector and the multiple second connecting rods of the second connector are arranged facing each other.

[0012] A further improvement of the steel structure membrane cladding installation structure of the present invention is that the locking plate, the inner arc tube, the outer arc tube, and the decorative strip are all segmented structures.

[0013] A further improvement of the steel structure membrane cladding installation structure of the present invention is that it also includes a waterproof lining layer for sealing the joint between the locking membrane plate and the membrane cladding.

[0014] This invention also provides a method for installing a steel structure membrane cladding, which uses the steel structure membrane cladding installation structure as described in any of the preceding claims to install the membrane cladding, including the following steps:

[0015] Using BIM to construct a three-dimensional model of the steel structure, steel structure components are ordered and the steel structure is constructed based on the three-dimensional model.

[0016] A 3D model of the membrane structure was constructed using BIM reference to the aforementioned 3D model of the steel structure.

[0017] Orders are placed based on the three-dimensional model of the membrane structure, and the membrane is installed in the order of the locking plate, the double helical arc tube, and the membrane finish.

[0018] A further improvement of the steel structure membrane cladding installation method of the present invention is as follows:

[0019] After the steel structure construction is completed, a three-dimensional scan of the constructed steel structure is performed. After the membrane structure three-dimensional model components are completed, the three-dimensional scan data is imported into the membrane structure three-dimensional model for collision checking and correction of the membrane structure three-dimensional model.

[0020] Orders are placed based on the revised 3D model of the membrane structure.

[0021] A further improvement of the steel structure membrane cladding installation method of the present invention is that, when installing the membrane cladding, tensioning is performed in the order of first the middle and then the two sides.

[0022] This invention includes, but is not limited to, the following beneficial effects:

[0023] 1. The installation node structure combining double helical arc tubes and locking plates reduces the number of membrane tensioning nodes, simplifies the construction process, shortens the construction cycle, and improves the tension fullness of the membrane.

[0024] 2. The waterproofing performance at the tension joints of the membrane surface is ensured by the installation of the waterproofing layer on the lining plate.

[0031] To address the problems of traditional membrane structures, such as numerous irregularly shaped locking nodes, high precision requirements, long construction periods, and inconsistent quality, this invention provides a steel structure membrane cladding installation structure and method. The following detailed description, in conjunction with accompanying drawings, further illustrates this steel structure membrane cladding installation structure and method using specific embodiments.

[0032] See Figure 2 and Figure 3As shown, a steel structure membrane cladding installation structure includes: a plurality of locking membrane plates 31 arranged outside the steel structure 1 and connected to the membrane cladding 2; the inner surface of the locking membrane plate 31 is connected to a first connector 32 for supporting the locking membrane plate 31 outside the steel structure 1 and forming a first through space 34 between the locking membrane plate 31 and the steel structure 1; the outer surface of the locking membrane plate 31 is connected to a second connector 33 for supporting a decorative component 4 outside the steel structure 1 outside the locking membrane plate 31 and forming a second space 35 between the decorative component 4 and the locking membrane plate 31; and a double helical arc tube spirally surrounding the steel structure 1, the double helical arc tube including an inner arc tube 51 that passes through the first through space 34 and is supported on the inner surface of the membrane cladding 2, and an outer arc tube 52 that passes through the second through space 35 and is pressed against the outer surface of the membrane cladding 2.

[0033] Specifically: See Figure 1 As shown, the steel structure 1 in this embodiment is cocoon-shaped, including a top circular tube 11, a bottom circular tube 12, and multiple radial arched main rods 13 that are circumferentially spaced between the top circular tube 11 and the bottom circular tube 12 and are connected by the first connecting member 32; the decorative component 4 includes multiple radial decorative strips; multiple locking plates 31, multiple radial decorative strips, and multiple radial arched main rods 13 are arranged in a one-to-one correspondence.

[0034] This embodiment adopts an installation node structure that combines a double-helix arc tube with a locking plate, which reduces the number of membrane tensioning nodes, simplifies the construction process, shortens the construction cycle, and uses the inner arc tube as the inner lining of the membrane to improve the tension fullness of the membrane. The outer arc tube can further position the membrane and also serve as a decoration.

[0035] In a preferred embodiment, in order to facilitate the tensioning of the membrane surface, the membrane surface 2 in this embodiment includes multiple membrane blocks for covering each of the two adjacent radial arched main rods 13. The first connector 32 and the second connector 33 are both connected to the middle position of the locking plate 31, and the two sides of the locking plate 31 form locking edges for the overlapping of two adjacent membrane blocks.

[0036] In a preferred embodiment: the first connector 32 includes a plurality of first connecting rods spaced apart along the length of the locking diaphragm plate 31, the plurality of first connecting rods dividing the first passage space 34 into a plurality of first compartments through which the inner arc tube 51 selectively passes; the second connector 33 includes a plurality of second connecting rods spaced apart along the length of the locking diaphragm plate 3, the plurality of second connecting rods dividing the second passage space 35 into a plurality of second compartments through which the outer arc tube 52 selectively passes.

[0037] Furthermore, in order to improve the stability of the installation structure, in this embodiment, the multiple first connecting rods of the first connector 32 and the multiple second connecting rods of the second connector 33 are arranged facing each other.

[0038] As a preferred embodiment, in order to facilitate the installation of the membrane structure, in this embodiment, the locking membrane plate 31, the inner arc tube 51, the outer arc tube 52 and the decorative strip 4 are all segmented structures. During installation, they can be pre-assembled into sections, and then the assembled sections are hoisted as a whole to the outside of the steel structure 1 for installation.

[0039] As a preferred embodiment, since there are gaps at the connection nodes of the membrane structure (i.e., the junction between the locking membrane plate 31 and the membrane surface 2), which do not have water-tightness conditions, the installation structure in this embodiment also includes a waterproof lining layer for sealing the joint between the locking membrane plate 31 and the membrane surface 2, so as to achieve the function of ensuring water tightness in the building.

[0040] A method for installing membrane cladding using the aforementioned steel structure membrane cladding installation structure, still taking the aforementioned "cocoon"-shaped steel structure as an example, is described below. Figures 1 to 3 As shown, the steps include:

[0041] Step 1: Use BIM to build a 3D model of the steel structure, and then order steel structure components and construct the steel structure based on the 3D model.

[0042] Specifically, the "cocoon"-shaped steel structure is a single-layer reticulated shell with a relatively complex structure. The main steel structural components involved are steel pipe components. This method uses TEKLA 3D modeling and solid coordinate system for drawing. When processing the steel structural components, the steel pipes are cut at their intersections using a CNC 5D or 6D intersection cutting machine. Medium-frequency induction heating is used to bend the steel pipes under localized heating conditions. To accelerate the construction progress of the steel structure, this method divides the installation of the steel structural components into four symmetrical areas along the central axis of the overall steel structure. To ensure the stability of the structural installation process, each area is equipped with a truck crane for symmetrical hoisting. Before each part is installed, embedded parts are pre-embedded at the construction location of the steel structure. Then, the bottom circular pipe 12 / top circular pipe 11 and the color steel top secondary steel beam are installed. Next, the connected radial arched main rod 13 is installed. Then, the top second and third ring rods are installed. Finally, the remaining ring rods and diagonal rods are installed.

[0043] Step 2: Use BIM to construct a 3D model of the membrane structure based on the 3D model of the steel structure.

[0044] Step 3: Order according to the 3D model of the membrane structure and install it in the order of the locking plate, the double helical arc tube and the membrane finish.

[0045] Specifically, the unique "cocoon"-shaped building is an irregularly shaped hyperboloidal single-unit structure requiring both interior and curtain wall construction. Conventional two-dimensional order placement methods cannot accurately determine the layout and order placement; therefore, it is necessary to collaborate with aluminum panel manufacturers and professional membrane structure companies to conduct overall BIM modeling, analyzing and simulating the finishing relationship between aluminum panels and wood veneer, the layout and segmentation of the aluminum panels themselves, and the perforation methods for model confirmation. The installation nodes of the membrane veneer are decomposed, and the model's difficulties are addressed through explanation, component disassembly of installation nodes, and CNC machining to improve processing accuracy. Among these:

[0046] Regarding the fabrication and installation of the membrane panel 31 and decorative components 4: The decorative components are configured in multiple sections according to the radial arched main rod 13. Each section is decomposed into 4 to 5 segments based on the 3D model of the membrane structure, and the arc curves are extracted, with arc lengths ranging from 23 meters to 28 meters, and each segment is assigned a number. Correspondingly, the membrane panel 31 can also be configured in multiple segments. Each segment of the membrane panel 31 is connected to a first connecting rod and a second connecting rod. In the backstage, all the decomposed decorative components are assembled onto the corresponding membrane panels, transported to the site as assembled parts, and then assembled.

[0047] Regarding the fabrication and installation of the double helical arc tube: the inner arc tube 51 and the outer arc tube 52 are set up in a corresponding manner and constructed along the helical arc shape. It can be set up in multiple sections. Each section selectively passes through the first compartment and the second compartment according to the position requirements. The outer arc tube 52 serves as a decorative line, and the inner arc tube 51 functions as a backing membrane veneer 2 to improve the tension fullness of the membrane veneer 2.

[0048] Regarding the fabrication and installation of the membrane cladding: Since both the membrane locking panel 31 and the decorative component 4 are long strips, even when divided into multiple sections, their length is still relatively long and the load is large. Changes in curvature and verticality are prone to occur during transportation and hoisting. To clarify the error dimensions, the membrane locking panel 31 and decorative component 4, already installed on the steel structure 1, were scanned and manually re-measured. The obtained data was matched with the 3D model of the membrane structure to clarify the error values. Then, the membrane cladding was accurately ordered. Based on the 3D model of the membrane structure, and following the position of the double-helix arc tube corresponding to the membrane segment joints, BIM simulation was used for layout decomposition and ordering. When tensioning the membrane cladding, refer to... Figure 4 As shown, tensioning practices were conducted in four sequences: Sequence 1 involved simultaneously tensioning from top to bottom towards the center; Sequence 2 involved tensioning from bottom to top; Sequence 3 involved tensioning from top to bottom; and Sequence 4 involved simultaneously tensioning from the center up and down. Sequence 4 yielded the best tensioning effect.

[0049] Step 4: After the membrane structure is installed, proceed with the floodlighting construction. Lay longitudinal and transverse steel wires, and fix point light sources at their intersections. The distance between the two ends of the light fixtures and the membrane surface should be approximately 200mm, and the distance between the center point and the membrane surface should vary from approximately 300mm to 500mm. Connect the steel wires of the light fixtures to the main steel structure using clamps to increase the number of point light sources per square meter, thus avoiding weak light at the center and excessive light at the edges.

[0050] Preferably, in order to achieve water tightness in the building, after the membrane structure is installed, a waterproof lining layer is set between the membrane structure and the steel structure, and the gaps between the lining joints are waterproofed. The specific construction process is as follows: apply masking tape - apply metal waterproof primer - apply waterproof elastic tape - apply the first coat of film - apply non-woven fabric (select according to the situation) - apply the second coat of film - remove the masking tape - quality inspection.

[0051] As a preferred implementation, since construction errors are inevitable after the main steel structure is completed, and the membrane structure is attached to the steel structure, the correction of the steel structure data is particularly important. Therefore, before performing step 3, the constructed steel structure is scanned in three dimensions using equipment such as a 3D laser scanner, and the three-dimensional scan data is imported into the three-dimensional model of the membrane structure for collision checking to correct the three-dimensional model of the membrane structure; when performing step 3, the order is placed based on the corrected three-dimensional model of the membrane structure.

[0052] This invention utilizes software modeling of steel and membrane structures, combining 3D scanning with manual measurement to import on-site data into the model for collision checks, and then integrates the model. This model-based ordering effectively improves material processing precision. The use of curved tube backing saves construction time and ensures the aesthetic appeal of the membrane structure. The PTFE membrane cladding structure, combined with curved shapes, results in a beautiful, simple, and vibrant form—a perfect blend of rigidity and flexibility, strength and beauty. Combined with nighttime lighting, it creates a dazzling and visually striking effect.

[0053] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
