[0002] Curtain wall is a non-load-bearing exterior wall enclosure on a building. It is a decorative lightweight facade wall structure commonly used in modern large and high-rise buildings. In modern buildings, curtain walls have replaced the traditional exterior wall construction methods of brick and stone or window-wall combination. Various strong, light and beautiful building materials are used to surround the periphery of the main structure, making the entire building beautiful, multifunctional and safe. Common curtain walls include glass curtain walls, metal curtain walls and stone curtain walls.

[0003] Curtain walls are mostly composed of structural frames and inlaid panels, and do not bear the main structural load. The structural frame is fixed with keels, which serve as the support and assembly structure of the inlaid panels and bear the gravity and environmental external force loads transmitted by the inlaid panels. The keel structure in the prior art is often assembled by traditional welding or riveting and other fixed forms. This method has the defects of low assembly efficiency, difficult to ensure assembly accuracy, difficult adjustment and correction, and difficult maintenance. In addition, the curtain wall keel structure assembled by traditional fixed connection methods often lacks flexibility in design and cannot meet the diverse needs of different building curtain walls.

[0004] Therefore, it is necessary to design a modular assembled curtain wall keel to improve assembly efficiency, ensure assembly accuracy, facilitate maintenance, and meet the diverse needs of building curtain walls. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0023] See also Figure 1 , Figure 2 A preferred embodiment of a modularly assembled curtain wall keel is provided. In this embodiment, the modularly assembled curtain wall keel is assembled as a structural frame by combining columns 2 and cross braces 7 arranged in a criss-cross pattern. The columns 2 are load-bearing structures, which are consistent with the corresponding curtain wall height and are arranged at equal intervals in the width direction of the curtain wall. The cross braces 7 are used to connect adjacent columns 2 and are arranged at equal intervals in the height direction of the curtain wall.

[0024] The cross brace 7 and the column 2 together form a grid-shaped frame assembly structure, and the frame assembly structure composed of the column 2 and the cross brace 7 is formed with assembly parts on one side of the facade for fixing and assembling the inlaid panels; the aforementioned assembly parts can be assembly structures such as supports, back bolts, and hanging seats known in the prior art, and the corresponding glass curtain wall panels, metal curtain wall panels and stone curtain walls used as inlaid panels can be formed on the facade of the curtain wall keel through assembly parts to complete the assembly of the curtain wall main body.

[0025] In this embodiment, the column 2 has guide grooves 1 on both sides along the length direction of the column 2. The guide grooves 1 can be used as positioning structures and guide structures for assembling lining blocks on the column 2, and can also be used to strengthen the structure of the column 2 itself. The corresponding cross brace 7 is a square tube structure; the column 2 and the cross brace 7 can be cut to a fixed length in the factory according to actual needs before entering the site for assembly, and after the fixed length cutting is completed, they can be transported to the site for assembly.

[0026] The modular components used to assemble the curtain wall keel include, in addition to the columns 2 and the cross braces 7, assembly pads and U-shaped bottom brackets 10:

[0027] The assembly pad includes a pad base 4, which is a plate structure matching the width of the column 2, and a back rib 3 matching the guide groove 1 is formed on the back side of the plate, and the assembly pad can be pre-positioned in the guide groove 1 by the back rib 3. The pad base 4 is also formed with ear plates 11 on both sides corresponding to the back rib 3 in the width direction, and threaded assembly holes are reserved on the ear plates 11 as an assembly structure for the assembly pad to be fixedly assembled with the column.

[0028] A lower-step protrusion 5 is formed on the front side of the plate surface of the lining block base 4, and the side surface of the lower-step protrusion 5 is an isosceles triangle, and the vertex of the isosceles triangle faces outward; the lower-step protrusion 5 extends from the middle to both sides of the width of the column 2, so that the size of the lower-step protrusion 5 in the width direction of the column 2 is greater than or equal to the side length of the cross brace 7; in addition, an upper-step protrusion 6 protruding outward is formed in the middle position of the top surface of the lower-step protrusion 5, and the upper-step protrusion 6 is an outward-protruding quadrangular pyramid, the top surface of the quadrangular pyramid faces outward, and the base of the quadrangular pyramid matches the inner hole of the cross brace 7.

[0029] In this embodiment, the surface of the upper-step protrusion 6 is covered with a rubber bushing 8, which covers the conical surface and the outer edge of the top surface of the upper-step protrusion 6 from the outside, and the rubber bushing 8 is formed with anti-skid patterns or anti-skid protrusions on the outer conical surface corresponding to the upper-step protrusion 6. In addition, two cross brace assembly holes 9 that penetrate the entire upper-step protrusion 6 are formed on the side of the upper-step protrusion 6, and the rubber bushing 8 has matching holes reserved at the positions of the corresponding cross brace assembly holes 9.

[0030] In another embodiment, the number of cross-bracing assembly holes 9 on the two-step protrusion structure may also be set to be greater than two, but at least two of the multiple cross-bracing assembly holes 9 are formed on the upper-step protrusion 6, and the other extra cross-bracing assembly holes 9 may be set on the upper-step protrusion 6 or on the lower-step protrusion 5.

[0031] The inner width and inner height of the U-shaped base bracket 10 match the size of the cross brace 7 so that the lower part of the connection position between the assembly pad and the cross brace 7 can be outsourced under the cross brace 7; in addition, the U-shaped base bracket 10 is also formed with outer pairs of through holes on the side panels on both sides that match the setting positions of the two cross brace assembly holes 9 on the upper step protrusion 6.

[0032] Before modular assembly of the curtain wall keel of this embodiment, the column 2 is first assembled at the selected position; then, the assembly lining block assembly hole is opened at the selected position on the column 2 by using a drill, and the assembly lining block hole is correspondingly formed on both sides of the guide groove 1, and corresponds to the threaded assembly hole positions reserved on the ear plates 11 on both sides of the assembly lining block; while drilling the column 2, the end face of the assembly end of the cross brace 7 can also be processed. During the processing, an inner V-shaped angle is cut on the end face of the cross brace 7, and the inner V-shaped angle matches the triangular side face of the lower-step protrusion 5. At the same time, a matching hole is opened on the inner side of the end face of the cross brace 7 corresponding to the position of the cross brace assembly hole 9 by using a drill.

[0033] In other embodiments, the side surface of the lower-step protrusion 5 can also be set as a right-angled triangle, and when it is set as a right-angled triangle, the hypotenuse of the corresponding right-angled triangle faces outward and upward, that is, one right-angled side of the right-angled triangle is parallel to the column 2 and remains close to it; during assembly, the cross brace 7 is directly beveled at the end face, and is assembled with the bevel of the right-angled triangle through the bevel, so that the other right-angled side of the right-angled triangle is parallel to the cross brace 7 and coincides with the bottom surface of the cross brace 7.

[0034] When the curtain wall keel of this embodiment is assembled in modular combination, the position is pre-positioned by using the assembly lining block through the back rib 3 and the guide groove 1, and then the threaded assembly hole position reserved on the ear plate 11 is passed through the threaded assembly part I 12, that is, Figure 1 The style shown completes the assembly of the lining block on both sides of the column 2; when the lining block is assembled on one side of the column 2, the assembly method is similar.

[0035] In another embodiment, in order to further improve the structural stability of the assembly block on the column 2, limiting bosses can be arranged at intervals on the guide groove 1. The limiting bosses are also fixed to the column by threaded assembly. The limiting bosses can support the assembly block at the bottom surface of the assembly block.

[0036] After the assembly lining block is assembled, the cross brace 7 can be mounted on the surface of the assembly lining block. During assembly, the cross brace 7 can be pressure-mounted on the surface of the lower-step protrusion 5 through the pre-processed inner V-angle. During the press-fitting process, the cross brace 7 can be pressed against the surface of the upper-step protrusion 6 at the inner hole position through the deformation of the rubber bushing 8. After the press-fitting is in place, the U-shaped base 10 is mounted from the bottom surface of the joint between the cross brace 7 and the assembly lining block. After the mounting is completed, the threaded assembly parts II 13 can be used to mount the overlapping cross brace assembly holes 9 (on the upper-step protrusion 6), the mounting holes (pre-drilled on the cross brace 7 before assembly) and the outer through holes (U-shaped base 10) as shown in the following figure. Figure 2 The illustrated style is used for pairing, that is, the assembly of the cross brace 7 on the assembly pad is completed. This assembly method can make the assembly connection between the cross brace 7 and the assembly pad more tightly, thereby improving the stability and load-bearing capacity of the curtain wall keel.

[0037] In different embodiments, by changing the size and quantity of the assembly pads, the columns 2, and the cross braces 7 to adjust the density of the nodes on the corresponding structural frame, the diverse needs of different building curtain walls can be easily met, making the curtain wall keel more flexible and customizable. At the same time, due to the modular design, the assembly process of the curtain wall keel is simpler, faster and more accurate, which improves the assembly efficiency, reduces the welding work, reduces the cost, and also facilitates the subsequent maintenance and replacement.
