DETAILED DESCRIPTION

[0033] In the description of the present invention, it should be noted that the terminology nouns in the various embodiments, such as "up", "down", "front", "back", "left", "right", etc., which indicate directions, are only for the convenience of describing the present invention, and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Such directional nouns do not constitute a limitation on the present invention.

[0034] The terms "first", "second", "third", "fourth", "fifth" and "sixth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", "third", "fourth", "fifth" and "sixth" may explicitly or implicitly include at least one of the features.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or a rotational connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 3 As shown, a curtain wall connecting device is used to connect a curtain wall with a steel structure, the curtain wall connecting device includes a first connecting component 2, a second connecting component 3 and a third connecting component 4, the second connecting component 3 includes a first connecting plate 31 and a second connecting plate 32, the first connecting component 2, the first connecting plate 31, the second connecting plate 32, and the third connecting component 4 are connected in sequence, the angle and / or the spacing between the first connecting plate 31 and the second connecting plate 32 are adjustable, the first connecting component 2 is also suitable for connecting to the steel structure, and the third connecting component 4 is also suitable for connecting to the curtain wall.

[0038] In one embodiment of the present invention, when the steel structure is located above the curtain wall, the first connecting plate 31 can be located above the second connecting plate 32, the first connecting plate 31 can be welded to the first connecting component 2, the first connecting component 2 can be welded to the steel structure, and the third connecting component 4 can be connected to the curtain wall by welding, bolts, etc. The first connecting component 2 is welded in advance and then assembled. Due to mistakes made by welders or installers, the first connecting component 2 on the steel structure may not completely correspond to the curtain wall. There may be a certain angle between the first connecting plate 31 and the curtain wall. The second connecting plate 32 can be connected to the first connecting plate 31 by bolts. The distance between the first connecting plate 31 and the second connecting plate 32 can be adjusted by nuts and screws. The distance between the first connecting plate 31 and the second connecting plate 32 can be changed by tightening and loosening the nuts. There can be multiple nuts and screws. By adjusting multiple nuts and screws, the first connecting plate 31 can be aligned with the second connecting plate 32. The second connecting plate 32 is adjusted to a position parallel to each other, so that the first connecting plate 31 and the second connecting plate 32 are evenly stressed, and the first connecting plate 31 with an angle is connected to the second connecting plate 32. The second connecting plate 32 is also suitable for connecting with the third connecting assembly 4, and the third connecting assembly 4 can fix two curtain walls at the same time, so that the curtain wall is fixed on the steel structure through the curtain wall connecting device; when it is necessary to adjust the angle of the curtain wall relative to the steel structure, the first connecting plate 31 and the second connecting plate 32 can be tilted by adjusting a plurality of nuts and screws, and the angle between the first connecting plate 31 and the second connecting plate 32 can be adjusted at the same time. The steel structure is also easily affected by temperature. In areas with large temperature differences, the steel structure is deformed due to the influence of temperature. The angle and spacing between the first connecting plate 31 and the second connecting plate 32 can be adjusted to eliminate the influence of the deformation of the steel structure.

[0039] In another embodiment of the present invention, when the steel structure is located below the curtain wall, the first connecting plate 31 may also be located below the second connecting plate 32. The effect of this embodiment is the same as that of the above embodiment and will not be repeated here.

[0040] The advantage of such a setting is that by adjusting the angle between the first connecting plate 31 and the second connecting plate 32, the first connecting component 2 and the third connecting component 4 which are not in the same plane can be connected through the first connecting plate 31 and the second connecting plate 32, so as to fix the curtain wall on the steel structure, and by adjusting the relative position of the first connecting plate 31 and the second connecting plate 32, the curtain wall can be better fixed on the steel structure through the curtain wall connecting device to reach the designed position, and by adjusting the angle between the first connecting plate 31 and the second connecting plate 32, the deflection of the first connecting component 2 pre-welded on the steel structure due to processing or construction errors can be absorbed to achieve the fixing of the curtain wall on the steel structure, and the uneven force between the first connecting plate 31 and the second connecting plate 32 can be eliminated to ensure safety. By adjusting the distance between the first connecting plate 31 and the second connecting plate 32, the curtain wall located in different planes can be connected to the steel structure, preventing the curtain wall and the steel structure from being unable to be connected due to construction errors, and eliminating construction errors. Furthermore, two curtain walls are fixed simultaneously by the third connection assembly 4. When the curtain wall angle needs to be adjusted, the angle between the two curtain walls and the steel structure can be controlled simultaneously by adjusting the angle between a pair of the first connection plates 31 and the second connection plates 32.

[0041] like Figure 6 and Fig.11 As shown, it also includes a first limiting plate 35 and a second limiting plate 36. The first limiting plate 35 is provided with a second rectangular hole 351, a third rectangular hole 352 and a second circular hole 353. The second limiting plate 36 is provided with a fourth rectangular hole 361 and a sixth circular hole 362. The second connecting plate 32 also includes a fourth fastener 325 and a fifth fastener 326. A connecting column 311 is provided on the first connecting plate 31. The connecting column 311 is respectively penetrated in the second rectangular hole 351 and the sixth circular hole 362. The fourth fastener 325 is suitable for being penetrated in the third rectangular hole 352 to connect the first limiting plate 35 and the second connecting plate 32. The fifth fastener 326 is suitable for being penetrated in the fourth rectangular hole 361 and the second circular hole 353 to connect the first limiting plate 35 and the second limiting plate 36.

[0042] One end of the connecting column 311 can be welded to the first connecting plate 31, and a through hole 321 is provided on the second connecting plate 32. The other end of the connecting column 311 passes through the through hole 321. The through hole 321 can guide the connecting column 311, so that the first connecting plate 31 can move along the axial direction of the through hole 321 through the connecting column 311. During installation, the second connecting plate 32 is first connected to the curtain wall, and then the curtain wall is installed on the first connecting plate 31 through the second connecting plate 32. After adjusting the position, it is fixed by the first limiting plate 35 and the second limiting plate 36.

[0043] The diameter of the through hole 321 may be larger than the diameter of the connecting column 311. When adjusting the angle between the second connecting plate 32 and the first connecting plate 31, the second connecting plate 32 rotates relative to the first connecting plate 31. At this time, the diameter of the through hole 321 is larger than the diameter of the connecting column 311, so that the connecting column 311 can avoid the connecting column 311 when it rotates. Figure 4 In the direction of the middle Y-axis, during installation, first adjust the positions of the second connecting plate 32 and the first connecting plate 31 in the X-axis direction, and then install the first limiting plate 35 on the second connecting plate 32 to fix the adjusted first connecting plate 31 and the second connecting plate 32 in the X-axis direction, so as to limit the degree of freedom of the connecting column 311 in the X-axis, so that the connecting column 311 cannot move in the X-axis direction.

[0044] The third rectangular hole 352 is arranged along the X-axis direction, and the fourth fastener 325 is passed through the third rectangular hole 352 to fix the first limiting plate 35 on the second connecting plate 32. There are multiple fourth fasteners 325, and the third rectangular hole 352 corresponds to the fourth fastener 325. Through the multiple fourth fasteners 325 and the third rectangular hole 352, the first limiting plate 35 can be prevented from rotating relative to the second connecting plate 32, thereby causing inaccurate positioning of the connecting column 311.

[0045] The second circular hole 353 is used to avoid the fifth fastener 326, and the fifth fastener 326 is installed on the second connecting plate 32. When the second connecting plate 32 is offset relative to the first connecting plate 31, the fifth fastener 326 of the second connecting plate 32 will move with the second connecting plate 32. At this time, the fifth fastener 326 can be avoided through the second circular hole 353. The second limiting plate 36 is installed after the first limiting plate 35 is installed. The fourth rectangular hole 361 opened on the second limiting plate 36 is used to avoid the fifth fastener 326. The fifth fastener 326 is used to limit the displacement of the connecting column 311 in the Y-axis direction. After adjusting the angle between the second connecting plate 32 and the first connecting plate 31 in the Y-axis direction, the second limiting plate 36 is fixed to the first limiting plate 35 through the fifth fastener 326, and the fixing of the connecting column 311 is completed in sequence.

[0046] like Fig.10 and Fig.11 As shown, the fourth rectangular hole 361 is arranged in the same direction as the second rectangular hole 351. The fifth fastener 326 is installed on the second connecting plate 32. When the second connecting plate 32 rotates in the Y-axis direction, the fifth fastener 326 will move with it. Since the X-axis direction has been limited by the first limiting plate 35, the connecting column 311 can only move or rotate along the Y-axis direction. Since the fifth fastener 326 has the same movement direction as the connecting column 311, the fourth rectangular hole 361 is arranged in the same direction as the second rectangular hole 351, so the fifth fastener 326 can be avoided. After adjusting the position, the second limiting plate 36 is installed on the first limiting plate 35 through the fifth fastener 326.

[0047] like Figures 1 to 3 As shown, the second connecting assembly 3 further includes at least four groups of adjusting assemblies 34 , and the adjusting assemblies 34 are respectively used to adjust the angle and / or the distance between the first connecting plate 31 and the second connecting plate 32 .

[0048] Each group of adjustment components 34 is respectively located on the side of the connecting column 311 close to the curtain wall and the side close to the steel structure. The four groups of adjustment components 34 can be in a quadrilateral structure and are respectively located on the first connecting plate 31 and the second connecting plate 32. The distances between the adjustment screws 341 and the adjustment nuts 342 at adjacent corners of the quadrilateral structure can be equal. A group of adjustment components 34 can include one adjustment screw 341 and four adjustment nuts 342. When adjusting the distance and angle between the first connecting plate 31 and the second connecting plate 32, the adjustment screws 341 and the adjustment nuts 342 on the four groups of adjustment components 34 are adjusted respectively. After the first connecting plate 31 and the second connecting plate 32 are adjusted to a suitable position, the first connecting plate 31 and the second connecting plate 32 are fixed by the screws 341 and the adjustment nuts 342.

[0049] like Figures 1 to 3 As shown, the adjustment assembly 34 includes an adjustment screw 341 and a plurality of adjustment nuts 342; a first mounting hole 312 is formed on the first connecting plate 31, and a second mounting hole 322 is formed on the second connecting plate 32; the adjustment screw 341 is penetrated through the first mounting hole 312 and the second mounting hole 322; two adjustment nuts 342 are provided on both sides of the first connecting plate 31 and the second connecting plate 32; the adjustment nuts 342 are threadedly connected to the adjustment screw 341; the diameter of the adjustment screw 341 is smaller than the diameter of the first mounting hole 312 and the second mounting hole 322, so as to facilitate the insertion of the adjustment screw 314; the first mounting hole 312 and the second mounting hole 322 are provided Gaskets are provided on both sides, and the area of ​​the gaskets is larger than the area of ​​the first mounting hole 312 and the second mounting hole 322. The gaskets can cover the first mounting hole 312 and the second mounting hole 322. Each gasket is clamped by an adjusting nut 342 respectively, and an opening is opened on the gasket, and the adjusting screw 314 can pass through the opening on the gasket. When it is necessary to adjust the distance between the first connecting plate 31 and the second connecting plate 32, the pressure of the adjusting nut 342 on the gasket is loosened, and the distance between the first connecting plate 31 and the second connecting plate 32 is moved. After adjusting to a suitable position, the adjusting nut 342 is tightened to achieve the distance adjustment between the first connecting plate 31 and the second connecting plate 32.

[0050] Two adjusting nuts 342 can be respectively provided on both sides of the first connecting plate 31 and the second connecting plate 32, and the adjusting screws 341 are respectively penetrated in the first mounting hole 312 of the first connecting plate 31 and the second mounting hole 322 of the second connecting plate 32, and there can be multiple second mounting holes 322, and multiple second mounting holes 322 are arranged around the through hole 321, and multiple adjusting nuts 342 are respectively penetrated in the second mounting holes 322 corresponding thereto. When adjusting the distance between the first connecting plate 31 and the second connecting plate 32, the adjusting nuts 342 located on both sides of the first connecting plate 31 can be firstly clamped with the first connecting plate 31 through the adjusting screws 341. After clamping, only the adjusting nuts 342 located on both sides of the second connecting plate 32 can be adjusted as needed to achieve the second connecting plate 32 being closer to or farther away from the first connecting plate 31; similarly, the adjusting nuts 342 located on both sides of the second connecting plate 32 can be clamped with the second connecting plate 32 through the adjusting screws 341. After clamping, only the position can be adjusted as needed. The adjusting nuts 342 on both sides of the first connecting plate 31 can realize the second connecting plate 32 to be closer to or farther away from the first connecting plate 31; the adjusting nuts 342 on both sides of the first connecting plate 31 and the second connecting plate 32 can also be adjusted at the same time to realize the distance adjustment between the first connecting plate 31 and the second connecting plate 32. When the distance between the first mounting plate 31 and the second connecting plate 32 is adjusted by adjusting the screw rod 341 and the adjusting nut 342, the adjusting screw 341 may be axially offset relative to the first mounting hole 312 and the second mounting hole 322. At this time, the diameter of the first mounting hole 312 and the second mounting hole 322 is larger than the diameter of the adjusting screw 341. When adjusting the distance between the first mounting plate 31 and the second connecting plate 32, the screw rod 341 can be avoided, so as to prevent the inner side wall of the first mounting hole 312 and the second mounting hole 322 from being damaged or the height cannot be adjusted due to the axial offset of the adjusting screw 341 relative to the first mounting hole 312 and the second mounting hole 322.

[0051] like Figure 4 , Figure 5 As shown, the first connecting assembly 2 includes a connecting member 21 , and the connecting member 21 is slidably connected to the first connecting plate 31 along a direction parallel to the first connecting plate 31 .

[0052] The connecting member 21 may also include a first mounting plate 211 and a second mounting plate 313, wherein the first mounting plate 211 is connected to the connecting member 21, and the second mounting plate 313 is connected to the first connecting plate 31, a slide rail 2111 is provided on the first mounting plate 211, and a slide groove 3131 is provided on the second mounting plate 313, and the slide rail 2111 is slidably connected to the slide groove 3131.

[0053] The slide groove 3131 can be in a T-shaped, I-shaped or other structure. When the steel structure is processed and installed, misalignment may occur between the steel structure and the curtain wall. Conventional curtain wall connection devices cannot connect the misaligned curtain wall to the steel structure. In this embodiment, one side of the first mounting plate 211 can be welded to the connecting piece 21, and a slide rail 2111 is provided on the other side of the first mounting plate 211. One end of the second mounting plate 313 can be welded to the first connecting plate 31, and a slide groove 3131 can be provided on the other end of the second mounting plate 313. The slide rail 2111 is accommodated in the slide groove 3131. By relatively sliding the first mounting plate 211 and the second mounting plate 313, the position between the connecting piece 21 and the first connecting plate 31 can be changed, and the curtain wall and steel structure located in different planes can be connected.

[0054] like Figure 5 As shown, a side surface of the first mounting plate 211 on which the slide rail 2111 is disposed is in contact with a side surface of the second mounting plate 313 on which the slide groove 3131 is disposed.

[0055] When the first mounting plate 211 and the second mounting plate 313 slide relative to each other, the side surface of the first mounting plate 211 provided with the slide rail 2111 and the side surface of the second mounting plate 313 provided with the slide groove 3131 fit together, so that the first mounting plate 211 can slide smoothly relative to the second mounting plate 313, and the first mounting plate 211 and the second mounting plate 313 that fit each other can be in surface contact, so that when the two slide relative to each other, the support for the curtain wall is guaranteed, and the curtain wall can be prevented from falling off due to non-surface contact and uneven force.

[0056] like Figure 4 , Figure 5 As shown, the first connecting component 2 also includes a second fastener 22, the connecting member 21 includes a first mounting plate 211, the first connecting plate 31 includes a second mounting plate 313, the first mounting plate 211 is provided with a first rectangular hole 2112, the second mounting plate 313 is provided with a first circular hole 3132, and the second fastener 22 is suitable for passing through the first rectangular hole 2112 and the first circular hole 3132 to connect the first mounting plate 211 and the second mounting plate 313.

[0057] When it is necessary to connect curtain walls located in different planes with steel structures, the first mounting plate 211 and the second mounting plate 313 are connected by adjusting the positional relationship between the first mounting plate 211 and the second mounting plate 313. A first rectangular hole 2112 is provided on the first mounting plate 211, and the second fastener 22 can move in the first rectangular hole 2112. When the first mounting plate 211 is adjusted to a suitable position, the second fastener 22 simultaneously passes through the first circular hole 3132 and the first rectangular hole 2112 to fix the first mounting plate 211 and the second mounting plate 313, so that curtain walls located in different planes and steel structures can be connected through the curtain wall connecting device.

[0058] like Figure 4 , Figure 5 As shown, it also includes a first reinforcing plate 23, and the first reinforcing plate 23 is connected to the first connecting plate 31 and the second mounting plate 313 respectively.

[0059] The first reinforcing plate 23 can be perpendicular to one surface of the first connecting plate 31 and the second mounting plate 313, respectively. The two first reinforcing plates 23 and the first connecting plate 31 form an I-beam structure to enhance the torsional strength of the first connecting plate 31. The first reinforcing plate 23 can increase the strength of the first connecting plate 31 to avoid the first connecting plate 31 from breaking due to the first connecting plate 31 bearing the weight of the curtain wall for a long time. Under the action of cyclic stress or cyclic strain, one or more places of the first connecting plate 31 may crack or suddenly break completely after a certain number of cycles. The first connecting plate 31 that suddenly breaks may cause the curtain wall to fall off, which is very risky.

[0060] like Figure 4 , Figure 5 As shown, the connecting member 21 also includes a first connecting arm 212 and a second connecting arm 213 which are connected to each other. The first connecting arm 212 and the second connecting arm 213 together form a fully enclosed structure 24.

[0063] The length direction of the first connecting plate 31 is the Y-axis direction, and the two fully enclosed structures 24 are welded to the circumferential surface of the steel structure at the same time to increase the strength and ensure the firmness of the curtain wall after installation. In addition, the two fully enclosed structures 24 are used for simultaneous fixing, so that the curtain wall can still remain stable in areas with strong winds and sand, reducing the risk of the curtain wall falling off and ensuring safety.

[0064] like Figure 4 , Figure 5 As shown, a second reinforcing plate 25 is also included, and the second reinforcing plate 25 is connected to the two fully surrounding structures 24 respectively.

[0065] The second reinforcing plate 25 can be used to fix the two fully enclosed structures 24 on the first mounting plate 211, and can increase the connection strength between the fully enclosed structure 24 and the steel structure, so as to enhance the torsional strength of the fully enclosed structure 24 and prevent the fully enclosed structure 24 from deforming and causing collision between adjacent curtain walls, thereby preventing the curtain walls from breaking and falling off, causing danger.

[0066] like Figure 4 , Figure 5 As shown, the second reinforcing plate 25 is arranged obliquely relative to the first mounting plate 211 .

[0067] The side of the second reinforcing plate 25 away from the first mounting plate 211 can be Figure 5 The direction of the middle X-axis is offset to the left and right to avoid the steel structure.

[0071] One end of the curtain wall can be opened. During installation, one end of the third fastener 413 can be connected to the third connecting plate 42 first, and then the connecting hole 45 opened on the fifth connecting plate 412 can be aligned with the third fastener 413, so that the fifth connecting plate 412 can be moved along the axial direction of the connecting hole 45 through the third fastener 413, and the fifth connecting plate 412 can be installed in the limiting groove 44 of one of the curtain walls. After the fifth connecting plate 412 is installed, the fourth connecting plate 411 can be installed in the limiting groove 44 of the other curtain wall according to the above method. In the slot 44, the fourth connecting plate 411 and the fifth connecting plate 412 are fixed by the third fastener 413, so as to fix the two curtain walls; of course, the fifth mounting plate and the fourth mounting plate can be respectively installed in the curtain wall first, and then the third fastener 413 can be passed through the connecting holes 45 opened on the fourth mounting plate and the fifth mounting plate in sequence, so as to fix the two curtain walls. A seal 46 is installed between the two curtain walls, and the seal 46 can be a sealing strip. The two curtain walls are elastically sealed and contacted by the sealing strip to prevent sand and dust from entering.
