Description

Technical Field

[0001] The present application relates to the technical field of curtain walls, and in particular to a curtain wall connection structure and a curtain wall. Background Art

[0002] Curtain wall is a design and construction method of the exterior wall of a building, also known as curtain wall. This design of exterior wall system is different from traditional load-bearing walls. It is usually not responsible for bearing the weight of the building, but supports its own weight through a support system suspended on the building structure. In addition to providing a good building appearance, it can also play a role in insulation, sound insulation, heat insulation, and sun shading. Curtain walls are usually composed of a frame structure made of aluminum alloy or steel, and a covering composed of decorative panels such as glass, stone, and metal plates. It is one of the common design elements in modern buildings, especially in high-rise buildings and commercial buildings.

[0003] With the rapid development of urbanization, modern buildings are generally equipped with curtain walls on their exterior surfaces. In order to make the buildings more beautiful or to give them the function of a predetermined display effect, decorative components such as decorative panels and light strips are usually installed on the curtain walls of the buildings. Taking stone decorative panels as an example, they are generally fixed to the beams through hanging components such as "steel pin type", "short slot type" and "back bolt type", and then the beams are fixed to the columns, so as to realize the installation of decorative panels on the wall. In actual construction scenarios, the beams and columns are constructed first, and then the decorative panels are installed. The errors in the construction process will have an adverse effect on the seams (i.e. "gap alignment") and coplanarity of the decorative panels. In order to improve or eliminate this adverse effect, the prior art uses other structural parts to achieve three-dimensional adjustment of the decorative panels relative to the wall during installation, but the structure of the existing structural parts is relatively complex, which not only leads to a relatively complex connection process, but also occupies a large space, resulting in a large space between the decorative panels and the wall.

Some parts of this article are described by taking stone plate as an example. The number of decorative panels 7 can be determined according to the adaptability of the needs. Figure 1Only a part of the curtain wall is shown, and the number of decorative panels 7 shown is only for exemplary display. These decorative panels 7 can be arranged in an array, and two adjacent decorative panels 7 are aligned and reserved with a gap, and the minimum width of the gap can be determined according to the adaptability of the actual scene.

[0058] The crossbeam 2 may be an integrally stamped aluminum alloy component. Stamping simplifies the manufacturing process, and the aluminum alloy component is not easily corroded in an outdoor environment while meeting the structural strength requirements.

[0059] The hanging assembly 6 includes a hanging seat 61 and a hanging member 62. The hanging seat 61 includes a third connecting seat 611, a fourth connecting seat 612 and a hanging plate 613. The third connecting seat 611 of a single hanging seat 61 is used to fit with the second side wall 22 or the third side wall 23 of the crossbeam 2. The fourth connecting seat 612 of each hanging seat 61 is vertically connected to the third connecting seat 611. The hanging plate 613 is vertically connected to the fourth connecting seat 612 and is arranged in a direction toward the decorative panel 7.

[0060] In a scenario where a single connection structure is used to install two upper and lower adjacent decorative panels 7, such as Figures 3 to 5 As shown, the hanging assembly 6 is provided with two hanging seats 61 (respectively referred to as an upper hanging seat 61 and a lower hanging seat 61 ) and two hanging members 62 (respectively referred to as an upper hanging member 62 and a lower hanging member 62 ).

[0061] The assembly process and principle of the curtain wall are exemplified as follows:

[0062] First, place the nut of the first bolt 4 from one end of the beam 2 in the second track groove 25 of the first side wall 21, and move it to a preset position along the first direction x in the second track groove 25. The second connecting seat 32 of the angle bracket 3 is fitted with the first side wall 21 of the beam 2. The screw rod of the first bolt 4 passes through the first track groove 33 of the second connecting seat 32 of the angle bracket 3, and moves to a preset position along the second direction y in the first track groove 33. Tighten the nut to vertically connect the beam 2 to the column 1 through the angle bracket 3.

[0063] In one example, the first track groove 33 of the angle code 3 can be aligned with the second track groove 25 of the first side wall 21, or the two track grooves partially overlap, thereby increasing the adjustable range.

[0064] exist Figure 6 In the example shown, the ends of the cross beam 2 can be vertically connected to the columns 1 through the angle brackets 3, and a single column 1 is vertically connected to two cross beams 2; Figure 7 In the example shown, a single column 1 is vertically connected to a single beam 2. In actual scenarios, depending on the length of the single beam 2 and the number of decorative panels 7 to be installed, these two examples may exist at the same time.

[0065] Then, combine Figure 5As shown, a nut of a second bolt 5 is placed in the second track groove 25 of the third side wall 23 of the beam 2 from one end of the beam 2, and is moved along the first direction x in the second track groove 25 of the third side wall 23 to a preset position, the screw rod of the second bolt 5 passes through the third track groove 63 of the third connecting seat 611 of the lower hanging seat 61, and is moved along the third direction z in the third track groove 63 to a preset position, and the nut is tightened to fix the lower hanging seat 61 to the third side wall 23 of the beam 2.

[0066] Optionally, a sealing gasket 615 , such as a rubber sealing gasket, may be provided at the connection between the second bolt 5 and the third connection seat 611 to achieve sealing and buffering of the connection. The sealing gasket 615 may also be provided in the third track groove 63 of the third connection seat 611 .

[0067] Optionally, a side of the third connecting seat 61 facing away from the third side wall 23 can be provided with a serrated structure, which can prevent the third connecting seat 611 from sliding relative to the third side wall 23 of the beam 2 after being fixed with bolts, thereby preventing the decorative panel 7 from sliding relative to the beam 2, the column 1 and the wall.

[0068] Next, a mounting groove 70 extending along the first direction x is provided on the back side (i.e., the side facing the wall) of the lower decorative panel 7, such as a wedge-shaped groove, and a nut of a mounting bolt 9 is received in the mounting groove 70 from the side of the decorative panel 7 and moved to a preset position in the mounting groove 70 along the first direction x, and then the screw of the mounting bolt 9 passes through the lower hanging member 62, and the nut is screwed and tightened to connect the lower decorative panel 7 with the lower hanging member 62, and the lower belly plate of the lower hanging member 62 is clamped with the hanging plate (also called "lower hanging plate") 613 of the lower hanging seat 61, and the clamping point of the two (such as the outer surface of the lower hanging plate 613) can be provided with a rubber sleeve 614, which can achieve sealing and buffering of the clamping point. Optionally, the connection structure may include a third bolt 8, also called an "adjusting screw 8", which passes through the lower hanging member 62 from top to bottom and abuts against the lower hanging plate 613 of the lower hanging seat 61, and the third bolt 8 is screwed until the flatness of the construction standard is reached.

[0069] Combination Figure 4 As shown, the nut of another second bolt 5 is accommodated in the second track groove 25 of the second side wall 22 of the beam 2 from one end of the beam 2, and is moved along the first direction x in the second track groove 25 of the second side wall 22 to a preset position, the screw rod of the second bolt 5 passes through the third track groove 63 of the third connecting seat 611 of the upper mounting seat 61, and is moved along the third direction z in the third track groove 63 to a preset position, and the nut is tightened to fix the upper mounting seat 61 to the second side wall 22 of the beam 2.

[0070] Optionally, a sealing gasket 615 may be provided at the connection between the second bolt 5 and the third connecting seat 611, and the sealing gasket 615 may also be provided in the third track groove 63 of the upper hanging seat 61; a side of the third connecting seat 61 facing away from the third side wall 23 may also be provided with a serrated structure.

[0071] A mounting groove 70 extending along the first direction x, such as a wedge-shaped groove, is provided on the back side of the upper decorative panel 7 (i.e., the side facing the wall). The nut of another mounting bolt 9 is received in the mounting groove 70 from the side of the decorative panel 7 and moves to a preset position in the mounting groove 70 along the first direction x. Then, the screw rod of the mounting bolt 9 passes through the upper hanger 62, and the nut is tightened to connect the upper decorative panel 7 with the upper hanger 62. The upper belly plate of the upper hanger 62 is clamped with the hanging plate (also called "upper hanging plate") 613 of the upper hanging seat 61. The clamping place between the upper belly plate of the upper hanger 62 and the upper hanging plate 613 (for example, the outer surface of the upper hanging plate 613) can be provided with a rubber sleeve 614 to achieve sealing and buffering of the clamping place.

[0072] In the above construction process, the first bolt 4 cooperates with the second track groove 25 of the first side wall 21, and the second bolt 5 cooperates with the second track groove 25 of the second side wall 22 and / or the third side wall 23, so that the decorative panel 7 can be adjusted along the extension direction of the beam 2 (i.e., the "lateral" or "left-right direction"); the first bolt 4 cooperates with the first track groove 33 of the angle code 3, so that the decorative panel 7 can be adjusted along the extension direction of the column 1 (i.e., the "vertical" or "up-down direction"); the second bolt 5 cooperates with the third track groove 63 of the hanger 61, so that The decorative panel 7 is adjusted along a direction perpendicular to the decorative panel 7 (i.e., the "front and rear direction"). Here, the present application can achieve three-dimensional adjustment relative to the wall during the installation of the decorative panel 7, thereby improving or eliminating the adverse effects of construction errors on the seams and coplanarity of the decorative panel 7. Moreover, it is only necessary to improve the structure of the crossbeam 2. Each of the first bolt 4 and the second bolt 5, i.e., a single bolt, can achieve adjustment in two directions at the same time. The structure and connection process are simple, and the entire connection structure occupies a small space between the decorative panel 7 and the wall, which is conducive to improving assembly stability.

[0073] Please continue reading Figures 3 to 5 As shown, the groove depth of the corresponding side wall of the second track groove 25 is greater than the nut thickness of the corresponding bolt. Here, each nut has a certain activity space in the second track groove 25, that is, a certain activity space along the extension direction of the bolt. The nut and the groove bottom 251 of the second track groove 25 can be relatively arranged. Using this structural design, the present application can further adjust the decorative panel 7 along the extension direction of the bolt by adding a gasket at the nut.

[0074] In the above example, the first side wall 21, the second side wall 22, the fourth side wall 24 and the third side wall 23 of the beam 2 are connected end to end in sequence to form an isolation cavity 20, and a heat insulation material (not shown) may be provided in the isolation cavity 20. The heat insulation material includes polystyrene foam and polyurethane foam, which can enhance the heat insulation function of the beam 2, that is, improve the performance of the curtain wall as a whole. The polystyrene foam acts as an insulation barrier to reduce heat conduction, while the polyurethane foam further enhances the sealing and insulation effects through its efficient filling and sealing performance. This double insulation design can improve the performance of the curtain wall.

[0075] Specifically, based on the isolation cavity 20, polystyrene foam can be adhered to the inner wall of the isolation cavity 20, and adhered around the inner wall, so that the polystyrene foam encloses a material isolation cavity, and then polyurethane foam is poured into the material isolation cavity, thereby performing a double insulation design.

[0076] It should be noted that polystyrene foam has good thermal insulation properties, and it can be used as the side wall material of the isolation cavity 20 to play a thermal insulation role. In addition, polyurethane foam can be poured into the isolation cavity 20 to further fill the gaps and form a dense structure, which can improve the air tightness of the curtain wall, prevent air leakage and heat loss, enhance the overall thermal insulation effect, and prevent heat conduction caused by air convection. On the other hand, the preset thickness of the polystyrene foam can be 1 / 5-1 / 3 of the cavity height of the isolation cavity 20. The elasticity of the polystyrene foam itself can also be used to buffer the expansion of the polyurethane foam and the hard contact with the isolation cavity 20 after curing.

[0077] The combination of polystyrene foam and polyurethane foam can bring out the advantages of both materials and optimize the thermal insulation performance of the exterior curtain wall. At the same time, polystyrene foam can effectively isolate polyurethane foam from the corresponding profiles, facilitating subsequent specific disassembly and assembly needs and facilitating the reuse of profiles.

[0078] In order to make the polyurethane foam expand evenly in the material isolation cavity 20, reinforcing ribs may be provided in the isolation cavity 20. The reinforcing ribs extend to the opposite ends of the isolation cavity 20, and the reinforcing ribs are designed in a bow-shaped structure. Then, the reinforcing ribs can be mixed with the polyurethane foam in the material isolation cavity. Specifically, the bow-shaped reinforcing ribs help to evenly disperse the externally applied pressure throughout the isolation cavity 20 to avoid stress concentration in local areas. Mainly, the polyurethane foam will expand during the infusion process, which may cause uneven foaming. The reinforcing ribs serve as physical barriers to guide the polyurethane foam to diffuse evenly in the material isolation cavity 20, preventing the formation of gaps or The area with uneven bubbles and the reinforcing ribs provide a fixed frame support for the polyurethane foam during the foaming process, preventing the foaming material from flowing too fast or becoming irregularly shaped during expansion, thereby ensuring the integrity of the foaming filling; on the other hand, a certain expansion force will be formed after the polyurethane foam is solidified. The present application uses polystyrene foam as an elastic buffer and uses reinforcing ribs to divide the solidified area of ​​the polyurethane foam to reduce its expansion force. That is, the bow-shaped reinforcing ribs ensure that the polyurethane foam is evenly filled in the isolation cavity 20, avoiding the reduction of thermal insulation performance due to the concentration or uneven distribution of the polyurethane foam, while slowing down the expansion force of the polyurethane foam and improving the comprehensive performance of the curtain wall.

[0079] In other examples, the crossbeam 2 may only include the first side wall 21, the second side wall 22 and the third side wall 23, but not the fourth side wall 24. The first side wall 21, the second side wall 22 and the third side wall 23 are connected end to end in sequence, so that the crossbeam 2 is a triangle in the yz section as a whole, and optionally an isosceles triangle. Here, the second side wall 22 and the third side wall 23 are symmetrically arranged along the third direction z, and the connection between the second side wall 22 and the third side wall 23 theoretically corresponds to the gap between the upper and lower adjacent decorative panels 7. At this time, the second side wall 22 and the third side wall 23 are both inclined side walls, and are inclined toward the upper and lower adjacent decorative panels 7. Correspondingly, the third connecting seat 611 is also an inclined wall, and can be fitted with the corresponding second side wall 22 and the third side wall 23. The fourth connecting seat 612 can still be the aforementioned vertical wall, and only needs to increase the length.

[0080] Optionally, the cross beam 2 may further include an outwardly extending cross wall (not shown), which is arranged to extend along the third direction z, that is, parallel to the xz plane, and one side of the outwardly extending cross wall is connected to the cross beam 2, for example, Figure 3In the scenario shown, one side of the extended horizontal wall is connected to the fourth side wall 24 of the beam 2, and can be connected to the middle position of the fourth side wall 24; for another example, in the scenario where the beam 2 does not include the fourth side wall 24, one side of the extended horizontal wall can be connected to the connection between the second side wall 22 and the third side wall 23; the other side of the extended horizontal wall extends toward the gap between the vertically adjacent decorative panels 7. Here, along the direction perpendicular to the first side wall 21, that is, along the third direction z, the other side of the extended horizontal wall is exposed to the gap between the vertically adjacent decorative panels 7. The construction personnel can intuitively judge whether there is an error in the construction by whether the other side of the extended horizontal wall is exposed and whether the exposed other side of the extended horizontal wall is located on the same line, so as to judge whether the vertically adjacent decorative panels 7 are aligned.

[0081] The cross beam 2 may further include an outwardly extending vertical wall (not shown), which is arranged to extend along the second direction y, that is, parallel to the yz plane, and one side of the outwardly extending vertical wall is connected to the cross beam 2, for example, Figure 3 In the scenario shown, one side of the protruding vertical wall is connected to the fourth side wall 24 of the beam 2; for another example, in the scenario where the beam 2 does not include the fourth side wall 24, one side of the protruding vertical wall can be connected to the connection between the second side wall 22 and the third side wall 23; the other side of the protruding vertical wall extends toward the gap between the laterally adjacent decorative panels 7. Here, along the third direction z, the other side of the protruding vertical wall is exposed to the gap between the laterally adjacent decorative panels 7. The construction personnel can intuitively judge whether there is an error in the construction by whether the other side of the protruding vertical wall is exposed and whether the exposed other side of the protruding vertical wall is located on the same line, so as to judge whether the vertically adjacent decorative panels 7 are aligned.

[0082] The protruding vertical wall can be perpendicular to the protruding horizontal wall and form a cross shape. Optionally, the present application can set a light bar on the end face of the other side of the protruding vertical wall and / or the end face of the other side of the protruding horizontal wall. Since the gap between the stone decorative panels 7 is large, it can accommodate the light bar. In the direction perpendicular to the first side wall 21, that is, in the third direction z, the light of the light bar is exposed in the gap between the adjacent decorative panels 7 in the horizontal and / or vertical direction, thereby increasing the decorative effect of the entire curtain wall.

[0083] Please continue reading Figures 3 to 5 As shown, the first side wall 21 of the beam 2 may be provided with an extension portion 211 extending beyond the second side wall 22 and the third side wall 23 , and the waterproof board 10 laid on the column 1 is stacked on the extension portion 211 and fixed to the column 1 by screws.

[0084] Optionally, the waterproof board 10 can be an aluminum alloy plate with waterproof function; in addition, waterproof glue can be coated on the screw-tightening position, and the waterproof glue not only covers the nut of the screw, but also covers the end of the waterproof board 10 and the area between the second side wall 22 and the third side wall 23 respectively.

[0085] The present application also provides a curtain wall, such as Figure 1 and Figure 2 As shown, the curtain wall includes a plurality of decorative panels 7 and a curtain wall connection structure as in any of the above examples, each decorative panel 7 is connected to a hanger 62 of the curtain wall connection structure to be fixed relative to a column 1, and finally installed on a wall surface. Therefore, the curtain wall has the beneficial effects that can be produced by the curtain wall connection structure of the above corresponding example.

[0086] For example, in a scenario where the crossbeam 2 is provided with an outwardly extending horizontal wall and / or an outwardly extending vertical wall, along a direction perpendicular to the first side wall 21, the other side of the outwardly extending horizontal wall is exposed to the gap between the vertically adjacent decorative panels 7, and the other side of the outwardly extending vertical wall is exposed to the gap between the transversely adjacent decorative panels 7; the construction personnel can intuitively judge whether there is an error in the construction by whether the other side of the outwardly extending horizontal wall and / or the other side of the outwardly extending vertical wall is exposed, and whether they are located on the same line, so as to judge whether the corresponding adjacent decorative panels 7 are aligned, and a light strip can be set on the end face of the other side of the outwardly extending horizontal wall and / or the end face of the other side of the outwardly extending vertical wall to increase the decorative effect of the entire curtain wall.

[0087] It should be understood that the curtain wall provided in the embodiment of the present application is a complete curtain wall, for example, it can be a hidden frame curtain wall, and it also has the structure of a known curtain wall. Here, only the components involved in the coordination between the decorative panel 7, the column 1 and the beam 2 in the curtain wall are described, and other components are not described in detail.
