Description

Technical Field

[0001] The present invention relates to the field of curtain walls, in particular to an exterior decorative unit curtain wall system. Background Art

[0002] Existing traditional unit curtain wall systems with large exterior decorations, especially special exterior decoration materials with large deadweight such as UHPC (ultra-high performance concrete) and GRC (glass fiber reinforced concrete), all require the installation of high-content back-attached keels to assist in connecting and supporting these large exterior decoration components. This leads to a series of problems such as complex curtain wall systems, cumbersome assembly processes, high material consumption, and heavy unit panels. The common practice is to separate the large exterior decoration components with back-attached keels from the unit panels, and reserve the rear installation support arms for the exterior decoration components on the unit panels. After the unit body is installed on site, the exterior decoration components are installed separately. This will result in repetitive work on site twice, greatly increasing the on-site measures costs. At the same time, the split installation is not conducive to precision and quality control.

When the number of through holes is too large, it is necessary to perform load calculation on the overall structure of the C-shaped hollow decorative plate 3 to ensure that the opened through holes do not affect the overall structure, thereby ensuring the stability of the overall structure. For example, first determine the material, minimum thickness and hollow size of the C-shaped hollow decorative plate 3. The C-shaped hollow decorative plate 3 is made of stainless steel fiber, has a volume of 0.293 cubic meters, and weighs 702 kilograms; the minimum thickness is 50 mm, and the width of the oblique strip through holes and the width of the decorative plate side wall between the two through holes are both 100 mm. Figure 14 As shown; through the finite element calculation method, the maximum tensile stress of the surface element is analyzed, as shown in Figure 15 As shown; the finite element simulation is used to verify the size of the plate deformation value under the normal use limit load combination of the C-shaped hollow decorative plate 3, as shown in Figure 16 As shown, Figure 16In the figure, the maximum deformation value of the C-shaped hollow decorative plate 3 under wind load is: def=2.0mm<467mm*2 / 200=4.67mm, which meets the requirements; after the verification is passed, the corresponding size of the production design can be carried out according to the above parameters.

[0040] The overall unit body panel of the exterior decorative unit curtain wall system described in the present invention is divided into two parts: the inner glass curtain wall unit body, namely the unit body 2, and the outer C-shaped hollow decorative panel, namely the C-shaped hollow decorative panel 3. They are assembled separately and then combined together. All processing and assembly processes must be carried out in the factory to ensure that the quality and precision meet the requirements; Among them, the glass curtain wall unit body is composed of columns and top, middle and bottom beams to form a profile frame, and then the glass and aluminum panels are installed. The top and bottom aluminum panels need to be extended in advance to be used for hanging the C-shaped hollow decorative panel 3 panels. The support arm is an aluminum alloy support arm 26, and the C-shaped hollow decorative plate 3 panel is a four-point hanging to ensure safety and stability. Two support arms are arranged on the upper part of the unit body and two support arms are arranged on the lower part of the unit body. The support arm specifications are 200×230×10mm flat aluminum, and a U-shaped notch for hanging is reserved, namely the hanging groove 261. This notch can play a role in positioning and limiting. The position where the support arm extends out of the aluminum plate is well sealed to ensure waterproof performance; the C-shaped hollow decorative plate 3 part cancels the existing back keel, and adopts the calculation of its own strength performance In order to design a hollow structure, the material of the C-shaped hollow decorative panel 3 can be made of stainless steel fiber, carbon fiber, glass fiber, synthetic fiber and other materials mixed with concrete to form a corresponding ultra-high performance concrete; during installation, it is necessary to pre-embed M12 stainless steel bolt sleeves on the C-shaped hollow decorative panel 3 according to the position of the unit arm, and three stainless steel bolt sleeves are set at each position. At the same time, the position of the embedded sleeve on the panel of the C-shaped hollow decorative panel 3 is partially thickened from 30mm to 60mm to ensure the reliability of the connection; in addition, T-shaped aluminum hangers and Z-shaped hangers that can be adjusted in six directions are also designed. Combined with serrated correction gaskets and M10 stainless steel machine-made top screws, oblong holes are opened on the T-shaped aluminum hangers, realizing the multi-dimensional adjustment function of the C-shaped hollow decorative panel 3 relative to the unit in the directions of entry and exit, i.e. front and back, left and right, and height, i.e. up and down, so that the C-shaped hollow decorative panel 3 and the unit are assembled together within the allowable deviation range, and finally completing the processing and production of the combined unit with the C-shaped hollow decorative panel 3 decorative panel.

[0041] The C-shaped hollow decorative panel 3 of the present invention is more convenient and quick to process, and does not require secondary assembly of back-attached keels, which saves a large number of processes and improves production efficiency. At the same time, the amount of keels used is greatly reduced, reducing costs. The six-way adjustable hanger system simplifies the assembly process in the factory, making the panel assembly more convenient and smooth, and the ability to adapt to deviations is also stronger; at the same time, the structural system is more novel, and the problem of the stress strength of the C-shaped hollow decorative panel 3 itself is solved by adding fibers and checking the C-shaped hollow decorative panel 3, eliminating a large number of back-attached keels, making the internal space structure of the C-shaped hollow decorative panel 3 cleaner and tidier, so that the C-shaped hollow decorative panel 3 can be made into more hollow shapes, while ensuring the functional requirements of the curtain wall, achieving the required appearance effect, and providing more choices for the diversity of building appearance. At the same time, referring to this approach, it can be extended to other similar curtain wall construction systems with decorative panels, which can not only simplify installation and reduce costs, but also allow for more options for building exterior effects by avoiding internal space. It increases the options and needs for architectural shapes, saves a large amount of keel materials, reduces material processing accuracy requirements, simplifies factory assembly difficulty, and reduces the weight of unit panels a lot at the same time, bringing significant improvements and help in multiple dimensions such as effects, processing, assembly, transportation, hoisting, installation, and cost.

[0042] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
