Description

Technical Field

[0001] This application relates to the field of curtain walls, and in particular to a keelless metal curtain wall. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It hangs like a curtain and is a lightweight, decorative wall system commonly used in modern large and high-rise buildings. A curtain wall consists of panels and a supporting structural system. It is a building envelope or decorative structure that can have a certain degree of displacement relative to the main structure or can deform itself, and does not bear the load of the main structure.

[0003] Curtain walls have replaced traditional brick or window-wall construction methods, utilizing various strong, lightweight, and aesthetically pleasing building materials to surround the main structure, achieving a beautiful, multifunctional, and safe building. Traditional building curtain walls, including glass, metal, and stone curtain walls, all have a keel structure. The keel acts as a supporting structure to fix the curtain wall, especially the inlaid panels in metal curtain walls, and bears the weight and wind loads transmitted by the inlaid panels. However, the keel system also reduces the utilization of building space and increases the cost of the curtain wall, negatively impacting its widespread application. Utility Model Content

The mounting holes are evenly distributed, and each mounting hole has a limiting hole on its upper inner wall that connects to the bottom of the hole. Each mounting node includes a vertically arranged fixing plate, two scrapers with one end fixedly connected to both ends of the fixing plate, and two limiting blocks fixedly connected to the upper side of the other end of the scrapers. The other ends of the four scrapers are inserted into the four mounting holes, and the four limiting blocks are inserted into the four limiting holes.

[0007] Optionally, the height of each hanging hole is a, and the height from the upper side of each limiting block to the lower side of the corresponding scraper is b, where a ≥ b.

[0008] Optionally, each of the limiting holes extends outward through one side of the panel and is fitted with and inserted into a mounting block, with each mounting block having a vertical through opening at its end to form the limiting hole.

[0009] Optionally, two insertion holes are provided on both sides of the panel in the width direction, and each of the limiting blocks is provided with a positioning hole that can connect to the corresponding insertion hole, and a positioning rod is inserted into the connected insertion hole and the positioning hole.

[0010] Optionally, each of the mounting blocks has a through opening forming a central hole, and the two ends of each central hole are respectively connected to the corresponding insertion hole and the positioning hole. The positioning rod is simultaneously inserted into the connected insertion hole, the central hole, and the positioning hole.

[0011] Optionally, each of the aforementioned insertion holes has a circular hole at its opening, and the end of each of the aforementioned positioning rods is located within the corresponding circular hole and is fixedly connected to a pull plate located within the corresponding circular hole.

[0012] Optionally, each of the pull plates has a gap between it and the bottom of the corresponding circular hole, forming an operating hole.

[0026] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0027] This application discloses a keelless metal curtain wall.

[0028] Reference Figures 1 to 7 A frameless metal curtain wall includes a panel 1 and two hanging nodes. The panel 1 has four hanging holes 11 on one side in the thickness direction. The hanging holes 11 are evenly distributed, and each hanging hole 11 has a limiting hole 12 that connects to the bottom of the hole on its upper inner wall. Each of the two hanging nodes includes a vertically arranged fixing plate 2, two scrapers 3 with one end fixedly connected to both ends of the fixing plate 2, and two limiting blocks 4 with the other end of the scrapers 3 fixedly connected to the upper side. The other ends of the four scrapers 3 are inserted into the four hanging holes 11 one by one, and the four limiting blocks 4 are inserted into the four limiting holes 12 one by one.

[0029] When installing the panel 1, both fixing plates 2 are fixedly installed on the corresponding walls, so that both fixing plates 2 are vertically set, and the four limiting blocks 4 are all located on the upper side of the corresponding scraper 3. Then, the panel 1 is hung on the four scraper 3 at the same time, so that the scraper 3 enters the corresponding hanging hole 11 and the limiting block 4 enters the corresponding limiting hole 12, thus completing the installation. The hanging node is used to replace the keel, so that the keel is not needed, saving steel, relatively saving building space, and reducing construction costs.

[0030] The fixing plate 2 can be fixed to the wall by welding, pre-embedded bolts, etc., and the wall can be a steel structure real or false back support column, steel structure rod, or concrete column, etc. Corresponding to the surface of the wall, the fixing plate 2 can be a straight plate, curved plate, etc.

[0031] The height of each hanging hole 11 is a, and the height from the upper side of each limiting block 4 to the lower side of the corresponding scraper 3 is b, where a ≥ b.

[0032] To ensure that the scraper 3 and the limiting block 4, which are fixedly connected to each other, can be smoothly inserted into the hanging hole 11 at the same time to complete the installation, after the limiting block 4 is inserted into place, under the gravity of the panel 1, the limiting block 4 enters the corresponding limiting hole 12.

[0033] Reference Figure 3 and Figure 4 Each limiting hole 12 extends outward through one side of the panel 1 and is fitted with and inserted into a mounting block 13. The end of each mounting block 13 has a vertical through opening to form a limiting hole 12. This is so that after the hanging hole 11 and the limiting hole 12 are formed, the limiting hole 12 can be formed by inserting the mounting block 13.

[0034] The mounting block 13 has an overall "U" shaped structure, with a limiting hole 12 at its open end and a dovetail-shaped structure at its closed end.

[0035] Each mounting block 13 has a noise-reducing isolation pad 6 fixedly connected to its outer side. The noise-reducing isolation pad 6 reduces the transmission of noise between metal parts, thereby reducing the amount of external noise entering the room. The noise-reducing isolation pad 6 can be a rubber pad.

[0036] Reference Figures 1 to 7 Two insertion holes 14 are provided on both sides of the panel 1 in the width direction, and each limiting block 4 is provided with a positioning hole 41 that can connect to the corresponding insertion hole 14. A positioning rod 5 is inserted into the connected insertion hole 14 and positioning hole 41.

[0037] After the limiting block 4 enters the corresponding limiting hole 12, the positioning rod 5 is simultaneously inserted into the connected insertion hole 14 and positioning hole 41. By using the limiting of the positioning rod 5, the hanging node will not separate from the panel 1, thus ensuring the stable installation of the panel 1.

[0038] The positioning hole 41 has a chamfered opening to form a first guide surface 411, which guides the smooth insertion of the positioning rod 5.

[0039] Each mounting block 13 has a through-hole forming a central hole 131. The two ends of each central hole 131 are connected to the corresponding insertion hole 14 and positioning hole 41, respectively. The positioning rod 5 is simultaneously inserted into the connected insertion hole 14, central hole 131, and positioning hole 41. The panel 1, mounting block 13, and limiting block 4 are connected simultaneously by the positioning rod 5, so that the panel 1, mounting block 13, and hanging node will not detach, thus achieving stable installation of the panel 1.

[0040] In this design, a second guide surface 132 is formed by chamfering at the opening of the middle hole 131 connecting to the insertion hole 14, so as to guide the smooth insertion of the positioning rod 5 through the second guide surface 132.

[0041] Of course, during the installation process, before inserting the positioning rod 5, the mounting block 13 is first inserted into the corresponding limiting hole 12, and then the panel 1 is installed so that the scraper 3 and the limiting block 4 are inserted into the corresponding hanging hole 11. When inserted into place, under the gravity of the panel 1, the mounting block 13 presses down on the corresponding scraper 3, which can relatively prevent the mounting block 13 from coming out of the limiting hole 12.

[0042] Reference Figure 1 and Figure 2 Each insertion hole 14 has a circular hole 141 at its opening, and the end of each positioning rod 5 is located in the corresponding circular hole 141 and is fixedly connected to a pull plate 51 located in the corresponding circular hole 141. This allows the positioning rod 5 to be installed and removed via the pull plate 51, and the pull plate 51 being located in the corresponding circular hole 141 ensures that there will be no gaps when installing adjacent panels 1 due to the installation of the positioning rod 5.

[0043] Each pull plate 51 has a gap between its bottom and the corresponding round hole 141, forming an operating hole 52. This allows the operator to insert their fingers, tools, etc., into the operating hole 52 to pull the pull plate 51.

[0044] Reference Figure 1 and Figure 2 Each scraper 3 has a diagonal brace 7 fixedly connected to its middle end, and the ends of each diagonal brace 7 away from the corresponding scraper 3 are pressed against the panel 1. The diagonal brace 7 provides support to the panel 1 and creates a pushing effect on the panel 1. Under the combined effect of the pulling action of each limiting block 4, the installation stability of the panel 1 is maintained. At the same time, each diagonal brace 7 can provide support to the corresponding scraper 3, maintaining the structural strength of the scraper 3.

[0045] Each of the diagonal bracing plates 7 has a flexible layer 71 fixedly connected to its end that abuts against the panel 1. The flexible layer 71 can be made of rubber. The flexible layer 71 forms a soundproof barrier to reduce noise.

[0046] The other end of the bracing plate 7 can be fixedly connected to the middle end of the scraper 3 by bolts.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
