DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figure 1 As shown, the utility model provides a curtain wall, including a steel keel 1, a cement board 2 and a hanger assembly 3, through which the cement board 2 and the steel keel 1 at corresponding positions are connected to achieve stable connection and support between the two, ensuring that the wall can be safely and firmly installed at a predetermined position and bear the corresponding load. It should be noted that the curtain wall is a high-density cement fiber board curtain wall.

[0025] Read also Figure 2Specifically, the hanger assembly 3 includes a first hanger 31 for connecting the steel keel 1 located at the lower layer and the middle layer and the cement board 2, and a second hanger 32 for connecting the steel keel 1 located at the top layer and the top sealing of the conversion layer and the cement board 2. The first hanger 31 includes a first web 311, a first rib 312, a second rib 313, a third rib 314 and a first fixing portion 315. The first web 311 includes a first side surface 3111 and a second side surface 3111 disposed opposite to the first side surface 3111. The surface 3112 and the third side surface connecting the first side surface 3111 and the second side surface 3112, the first rib 312 is connected to the third side surface, the second rib 313 is arranged on the first side surface 3111 to enclose with the first rib 312 to form a first installation groove 316 adapted to the cement board 2, the third rib 314 is arranged on the second side surface 3112 to enclose with the first rib 312 to form a second installation groove 317 adapted to the cement board 2, and the first fixing part 315 is connected to the steel keel 1.

[0026] Based on the above structure, it can be known that the first hanger 31 is suitable for connecting the steel keels 1 and cement slabs 2 of the lower and middle layers of the building, and the first installation groove 316 matching the size of the cement slab 2 is formed by the first rib 312 and the second rib 313, so as to facilitate the embedding and installation of the cement slab 2. Similarly, the third rib 314 and the second rib 313 together form the second installation groove 317, which is used to fix the cement slab 2 from another direction, and the first fixing part 315 is connected to the steel keel 1 to ensure that the entire hanger can be firmly fixed on the steel skeleton. The second hanger 32 is suitable for connecting the steel keels 1 and cement slabs 2 at the top of the building and the top of the transition layer to adapt to the connection characteristics and load requirements of different levels.

[0027] In this embodiment, the installation groove structure in the first hanger 31 and the second hanger 32 is embeddedly connected to the cement board 2, so that a concealed fixing method is formed between the cement board 2 and the first hanger 31 and / or the second hanger 32, and there is no need to nail on the board surface, thereby eliminating the dense exposure of the nail heads, and significantly improving the neatness and beauty of the building facade. In addition, since there is no need to nail on the board surface, quality problems such as rust and color difference of the metal nail heads when the humidity is high or there is a corrosive environment are avoided.

[0028] In actual application, the steel keel 1 and cement board 2 located at the lower layer are connected by the first hanger 31, the steel keel 1 and cement board 2 located at the middle layer are connected by the first hanger 31, the steel keel 1 and cement board 2 located at the top layer are connected by the second hanger 32, and the steel keel 1 and cement board 2 located at the top seal of the transition layer are connected by the second hanger 32, so as to realize the connection between the cement board 2 and the steel keel 1 at the corresponding position to adapt to the connection characteristics and load requirements of different levels.

[0029] In some embodiments, the first hanger 31 also includes an abutment plate 318 extending along the first direction from a side of the first web 311 away from the third side surface, and the end surface of the abutment plate 318 away from the first web 311 is roughly flush with the end surface of the first fixing portion 315 away from the first rib 312, so that when the first hanger 31 is installed in place, the end surface of the abutment plate 318 will be in close contact with one side of the steel keel 1, achieving good contact and load conduction with the steel keel 1, while providing strong support. Through the setting of the above structure, the abutment plate 318 and the steel keel 1 are in contact with each other, which helps to control the vertical bending deformation caused by the force, ensure the stability and safety of the connection, and avoid connection failure or damage to the wall appearance due to excessive deformation.

[0030] In some embodiments, the first fixing portion 315 is connected to the third rib 314, and the side of the first fixing portion 315 facing away from the third rib 314 is connected to the steel keel 1, which includes a first connecting plate 3151 and a second connecting plate 3152 for connecting to the steel keel 1, and the second connecting plate 3152 is connected to the third rib 314 through the first connecting plate 3151. On the one hand, the first connecting plate 3151 is connected to the third rib 314, ensuring the continuity and stability of the overall structure of the hanger; on the other hand, it is connected to the second connecting plate 3152, realizing the effective combination of the first hanger 31 and the steel keel 1. The second connecting plate 3152 is provided with a first mounting hole 31524, which serves as a key channel for fixing the first hanger 31 to the steel keel 1. Bolts, rivets or other fasteners can be passed through the first mounting hole 31524 to firmly fix the first fixing part 315 of the first hanger 31 to the steel keel 1, thereby realizing a reliable connection between the first hanger 31 and the main steel structure of the building.

[0031] In some embodiments, the second connecting plate 3152 includes a first connecting section 31521, a second connecting section 31522 and a third connecting section 31523 which are connected in sequence. The second connecting section 31522 has a first mounting hole 31524. The first connecting section 31521 is connected to the third rib 314 through the first connecting plate 3151. A first angle R1 is formed between the first connecting section 31521 and the second connecting section 31522. The angle of the first angle R1 is 110-130°, so as to increase the rigidity of the connection through an appropriate angle, reduce stress concentration, improve the connection stability, and also facilitate construction personnel to assemble according to the required angle;

[0032] A second angle R2 is formed between the third connecting section 31523 and the second connecting section 31522. The angle of the second angle R2 is 110-130°, so as to also adapt to the required installation space and connection requirements, ensure that the first hanger 31 can fit the shape and direction of the steel keel 1, optimize the load transfer path, and avoid unnecessary deformation or stress loss.

[0033] In some embodiments, the second rib 313 includes a fourth side 3131 and a fifth side 3132 that are relatively arranged, and the width between the fourth side 3131 and the fifth side 3132 gradually decreases along the slot of the first mounting groove 316, that is, from the slot inward, the distance between the fourth side 3131 and the fifth side 3132 becomes narrower and narrower, so that a third angle R3 is formed between the extension lines of the fourth side 3131 and the fifth side 3132, and the angle of the third angle R3 is 3°-5°. Through the above-mentioned arrangement, this embodiment provides a gradually embedded guiding slope for the cement board 2 to be installed, so that the board body can slide into the first mounting groove 316 more easily and smoothly, thereby reducing the impact and damage to the board body during the installation process.

[0034] In addition, the width between the first rib 312 and the second rib 313 gradually increases along the notch of the first mounting groove 316, that is, the notch is wider than the bottom of the groove, so that a fourth angle R4 is formed between the extension lines of the first rib 312 and the second rib 313. The angle of the fourth angle R4 is 2.5°-3.5°, and is arranged in conjunction with the above-mentioned third angle R3, thereby providing a convenient insertion guide for the cement board 2, which is beneficial to construction positioning and quick and accurate installation.

[0035] In some embodiments, the width between the first rib 312 and the third rib 314 gradually increases along the slot opening of the second mounting slot 317, that is, the slot opening is wider than the slot bottom, so that a fifth angle R5 is formed between the extension lines of the first rib 312 and the third rib 314. The angle of the fifth angle R5 is 3°-5°, providing a gradually embedded guide slope for the cement board 2 to be installed, so that the board body can slide into the second mounting slot 317 more easily and smoothly, reducing the impact and damage to the board body during the installation process.

[0036] like Figure 3As shown, in some embodiments, the second hanger 32 includes a second web 321, a fourth rib 322, a fifth rib 323 and a second fixing portion 324. The fourth rib 322 and the second fixing portion 324 are symmetrically arranged about the center of the second web 321, that is, the fourth rib 322 and the second fixing portion 324 are symmetrically distributed around the central axis of the second web 321. This symmetrical layout can evenly distribute the load from the cement board 2 and ensure the stability of the second hanger 32 under stress. The fifth rib 323 is arranged on one side of the second web 321 to enclose with the fourth rib 322 to form a third mounting groove 325 that is compatible with the cement board 2, so as to provide a precise embedding position for the cement board 2, ensure that the board body is firmly fixed on the hanger, and form a good mechanical transmission. The second fixing portion 324 is provided with a second mounting hole 3241, so that bolts or other fasteners can pass through the hole to achieve effective fixation and connection between the second hanger 32 and the steel keel 1, thereby safely transferring the load of the cement board 2 to the steel structure system of the building.

[0037] In some embodiments, the fifth rib 323 includes a sixth side 3231 and a seventh side 3232 that are relatively arranged, and the width between the sixth side 3231 and the seventh side 3232 gradually decreases along the slot of the third mounting slot 325, that is, from the slot inward, the distance between the sixth side 3231 and the seventh side 3232 becomes narrower and narrower, so that a sixth angle R6 is formed between the extension lines of the sixth side 3231 and the seventh side 3232, and the angle of the sixth angle R6 is 3°-5°. Through the above-mentioned arrangement, this embodiment provides a progressively embedded guide slope for the cement board 2 to be installed, so that the board body can slide into the third mounting slot 325 more easily and smoothly, thereby reducing the impact and damage to the board body during the installation process.

[0038] In addition, the width between the fourth rib 322 and the fifth rib 323 gradually increases along the notch of the third installation groove 325, that is, the notch is wider than the bottom of the groove, so that a seventh angle R7 is formed between the extension lines of the fourth rib 322 and the fifth rib 323. The angle of the seventh angle R7 is 3°-5°, which is arranged in conjunction with the above-mentioned sixth angle R6, providing a convenient insertion guide for the cement board 2, which is beneficial to construction positioning and quick and accurate installation.

[0039] In some embodiments, the wall thickness of the first hanger 31 and the wall thickness of the second hanger 32 are not less than 1.6 mm to provide sufficient structural strength and rigidity to ensure that the first hanger 31 and the second hanger 32 will not deform too much under stress, thereby ensuring the stability of the wall structure.

[0040] In actual application, the curtain wall also includes a rubber pad 4. A rubber pad 4 is arranged between the first hanger 31 and the steel keel 1, and a rubber pad 4 is arranged between the second hanger 32 and the steel keel 1 to fill the small gap between the first hanger 31, the second hanger 32 and the keel to ensure a tighter connection and enhance the stability of the overall structure. At the same time, it can reduce the vibration and noise generated by the hard contact between the first hanger 31, the second hanger 32 and the steel keel 1.

[0041] It should be noted that the first hanger 31 and the second hanger 32 are both made of 6063-T6 aluminum profiles and fixed to each steel keel 1 behind each cement board 2 with ST5.5*30 stainless steel self-tapping screws. Since the cement board 2 with a floor height of more than 24m uses a back rib plate, the distance from the steel keel 1 surface to the finished surface of the cement board 2 is 35mm, and the cement board 2 is 15mm thick, leaving 2mm for the rubber pad 4 to be installed between the first hanger 31, the second hanger 32 and the steel keel 1 to ensure the stable connection between the first hanger 31 and the cement board 2.

[0042] In summary, the embodiment of the utility model provides a hanger assembly 3 and a curtain wall, which are embeddedly connected to the cement board 2 through the installation groove structure in the first hanger 31 and the second hanger 32, so that a concealed fixing method is formed between the cement board 2 and the first hanger 31 and / or the second hanger 32, without the need to nail on the board surface, thereby eliminating the dense exposure of the nail heads, and significantly improving the neatness and beauty of the building facade. In addition, since there is no need to nail on the board surface, quality problems such as rust and color difference of the metal nail heads when the humidity is high or there is a corrosive environment are avoided.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
