Description

Technical Field

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

[0002] As the exterior wall structure of modern buildings, curtain walls not only have good aesthetic effects, but also carry important functions such as heat preservation, sound insulation and wind protection. During the installation of curtain walls, the stability of the node connection structure is particularly critical, which directly affects the overall safety and stability of the curtain wall. Traditional curtain wall panel connections, especially at the rooftop, usually use a single connection point and H-shaped steel beam for fixing.

[0003] In the design of the curtain wall node connection at the roof position, the connection between the roof wall panel and the H-shaped steel beam is mostly fastened by a single bolt. Although this design can meet the basic connection requirements to a certain extent, when encountering severe weather conditions such as strong winds, the single connection point is not rational due to its poor force transmission path, which makes the connected steel beam prone to twisting and may even cause more serious safety hazards.

[0004] Therefore, how to improve the existing curtain wall node connection method to improve the connection stability between the roof wall panel and the H-shaped steel beam has become a technical problem that needs to be urgently solved in the current curtain wall technology field. Utility Model Content

[0005] In order to improve the connection stability between the roof wall panels and the H-shaped steel beams, the present application provides a curtain wall node connection structure.

[0006] The present application provides a curtain wall node connection structure, which adopts the following technical solution:

[0007] A curtain wall node connection structure, characterized in that:

[0008] A support frame, comprising an H-shaped steel beam, a horizontal truss and a vertical spar, wherein the vertical spar is provided in multiple and evenly spaced locations at the edge of the roof, and the H-shaped steel beam is transversely arranged at the top of the vertical spar;

[0009] A keel is arranged outside the support frame, and the keel is evenly spaced up and down to form a plurality of installation cavities;

[0010] Wall panels are installed in the installation cavity in a one-to-one correspondence;

[0011] A connecting plate, comprising a first connecting plate and a second connecting plate, wherein the first connecting plate is arranged near the top of the H-shaped steel beam, and the first connecting plate abuts against the inner wall of the installation cavity;

[0012] The second connecting plate is arranged on the keel, and a fixing plate corresponding to the second connecting plate is arranged at the bottom of the H-shaped steel beam, and the second connecting plate is connected to the fixing plate;

[0013] A connecting member, the connecting member connecting the first connecting plate and the keel;

[0014] The connecting member connects the second connecting plate and the fixing plate.

[0015] By adopting the above technical solution, when installing the curtain wall, first install the fixed support frame on the roof, then install the keel, and finally install the wall panel in the installation cavity of the keel. The keel is connected to the support frame through the first connecting plate and the second connecting plate, thereby improving the connection stability between the roof wall panel and the H-shaped steel beam.

[0016] Optionally, the connecting member includes a connecting bolt;

[0017] The connecting bolts include a first bolt and a second bolt, the first bolts are multiple and respectively penetrate the first connecting plate, and the first bolts are threaded on the keel;

[0020] Optionally, the connecting plate is formed with waist-shaped holes, and the waist-shaped holes include vertical waist-shaped holes and transverse waist-shaped holes;

[0021] The vertical waist-shaped hole is for the first bolt to pass through and is formed on the first connecting plate;

[0022] The transverse waist-shaped hole is for the second bolt to pass through and is formed on the second connecting plate.

[0023] By adopting the above technical solution, the second bolt slides in the transverse waist-shaped hole. At this time, the first bolt transmits a transverse force to the first connecting plate. At this time, the H-shaped steel beam supports the first connecting plate, reducing the possibility of torsion of the first connecting plate, thereby greatly improving the stability of the connection between the roof wall panel and the H-shaped steel beam.

[0024] Optionally, the connecting bolt abuts against the connecting plate and slides in the waist-shaped hole.

[0025] By adopting the above technical solution, the connecting bolts are screwed into place but not tightened, so that the connecting bolts can slide in the waist-shaped holes, which makes it convenient for the connecting plate to disperse the force and better adapt to the force it receives.

[0026] Optionally, the second bolt is in the same straight line as the web of the H-shaped steel beam.

[0027] By adopting the above technical solution, the H-shaped steel beam can better withstand the force transmitted by the second bolt.

[0028] Optionally, a rib is provided on a side of the H-shaped steel beam away from the wall panel, and the rib is located above the fixed plate and corresponds one to one.

[0029] By adopting the above technical solution, the setting of the H-shaped steel beam improves the stability of the H-shaped steel beam, so that when the fixed plate transmits the force to the H-shaped steel beam, the rib plate improves the resistance effect of the H-shaped steel beam to the force.

[0030] Optionally, the first connecting plate and the second connecting plate are respectively provided with a linkage plate, and the linkage plate is formed with a slot for the adjacent connecting bolts to be inserted.

[0031] By adopting the above technical solution, the connecting bolts are inserted into the slots, and the first bolts in the same straight line and the second bolts in the same straight line are respectively linked through corresponding linkage plates, thereby reducing the possibility of the first bolts and the second bolts becoming loose or falling off.

[0032] Optionally, the linkage plate includes a plate body, a mounting block and a retaining ring;

[0033] The slots are formed on the mounting blocks and correspond to each other one by one, and the mounting blocks are threadedly connected to the plate body;

[0034] The retaining ring is threadedly connected to the plate body, and the retaining ring abuts against a side of the mounting block away from the connecting plate.

[0035] By adopting the above technical solution, the mounting block is threadedly connected to the plate body, so that the slot is conveniently aligned with the bolt head of the connecting bolt, and then the mounting block is abutted by the retaining ring to limit the loosening of the connecting bolt.

[0036] Optionally, the first connecting plate is connected to the web of the H-shaped steel beam.

[0037] By adopting the above technical solution, the H-shaped steel beam can better support the first connecting plate.

[0038] In summary, the present application includes at least one of the following beneficial effects:

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1-6 This application is described in further detail.

[0049] An embodiment of the present application discloses a curtain wall node connection structure.

[0050] Embodiment 1

[0051] See also Figure 1The curtain wall node connection structure includes a support frame 1, and the support frame 1 includes an H-shaped steel beam 11, a horizontal truss and a vertical bar 12. There are multiple vertical bars 12 and they are evenly spaced along the extension track of the edge of the roof. The vertical bars 12 are fixed to the roof by bolts and other fixings. In order to strengthen the installation stability of the vertical bars 12, the vertical bars 12 are connected to the building walls and columns on the roof by horizontal trusses. When in use, the vertical bars 12 are supported by the horizontal trusses to improve the stability of the vertical bars 12. The H-shaped steel beam 11 includes a flange and a web. There are two flanges and they are fixed at the opposite ends of the web. The H-shaped steel beam 11 is fixed to the top of the vertical bar 12. The H-shaped steel beam 11 extends in the horizontal direction. Adjacent vertical bars 12 are connected and fixed by the H-shaped steel beam 11, and the web extends in the vertical direction.

[0052] The curtain wall node connection structure also includes a wall panel 3 and a keel 2. The keel 2 is arranged outside the support frame 1. A plurality of installation cavities 21 are evenly spaced on the keel 2. There are multiple wall panels 3 and they correspond to the installation cavities 21 one by one. The wall panels 3 are fixedly installed on the keel 2 and are located in the installation cavities 21. The depth of the installation cavity 21 is greater than the thickness of the wall panel 3.

[0053] See also Figure 1 and Figure 2 The curtain wall node connection structure also includes a connection plate 4, which includes a first connection plate 41 and a second connection plate 42. One end of the first connection plate 41 is fixed to the web of the H-shaped steel beam 11 and close to the top by welding, and the other end of the first connection plate 41 extends into the installation cavity 21, and the side wall of the first connection plate 41 abuts against the vertical inner wall of the installation cavity 21. The first connection plate 41 is located on the side of the wall panel 3 close to the H-shaped steel beam 11.

[0054] See also Figure 2 and Figure 3 The second connecting plate 42 is fixed to the vertical wall of the installation cavity 21 by welding. The second connecting plate 42 is located directly below the first connecting plate 41, and the top of the second connecting plate 42 abuts against the bottom of the H-shaped steel beam 11. A fixing plate 111 is fixed to the bottom of the H-shaped steel beam 11 by welding. The fixing plate 111 corresponds to the second connecting plate 42 one by one, and the second connecting plate 42 abuts against the fixing plate 111. A rib plate 112 is fixedly connected to the side of the H-shaped steel beam away from the wall panel. The rib plate 112 is fixedly connected to the web and flange of the H-shaped steel beam respectively. The rib plate 112 is located directly above the fixing plate and corresponds to each other one by one.

[0055] The curtain wall node connection structure also includes a connection member, which includes a connection bolt 5, and the connection bolt 5 includes a first bolt 51 and a second bolt 52. There are multiple groups of first bolts 51, each group of first bolts 51 corresponds to a first connection plate 41, and each group of first bolts 51 has multiple and are evenly spaced along the vertical direction. There are multiple groups of second bolts 52, each group of second bolts 52 corresponds to a second connection plate 42, and each group of second bolts 52 has multiple and are evenly spaced along the horizontal direction.

[0056] The connecting plate 4 is formed with a waist-shaped hole 6, which includes a vertical waist-shaped hole 61 and a transverse waist-shaped hole 62. The vertical waist-shaped hole 61 is formed in the first connecting plate 41, and the transverse waist-shaped hole 62 is formed in the second connecting plate 42. The first bolt 51 is passed through the vertical waist-shaped hole 61, and the first bolt 51 is threadedly connected to the keel 2. The second bolt 52 is passed through the transverse waist-shaped hole 62, and the second bolt 52 is threadedly connected to the fixing plate 111, and the second bolt 52 is in the same vertical line as the web of the H-shaped steel beam 11.

[0057] When the first bolt 51 and the second bolt 52 are installed and connected, the first bolt 51 is screwed to abut against the first connecting plate 41, but the first bolt 51 is not tightened. When the first connecting plate 41 is subjected to a large vertical force, the first bolt 51 can slide in the vertical waist-shaped hole 61. The second bolt 52 is screwed to abut against the second connecting plate 42, but the second bolt 52 is not tightened. When the second connecting plate 42 is subjected to a large lateral force, the second bolt 52 can slide in the lateral waist-shaped hole 62.

[0058] When the gravity and the vertical force acting on the wall panel 3 and the keel 2 are transmitted to the first connecting plate 41 and the second connecting plate 42, the first bolt 51 slides in the vertical waist-shaped hole 61. At this time, the hole wall of the horizontal waist-shaped hole 62 abuts on the second bolt 52, and then is transmitted to the H-shaped steel beam 11 through the fixing plate 111, so that the force is mainly transmitted to the H-shaped steel beam 11 through the second connecting plate 42; and the second connecting plate 42 abuts against the bottom of the H-shaped steel beam 11, and the bottom flange of the H-shaped steel beam 11 limits the second connecting plate 42, thereby reducing the possibility of twisting of the second connecting plate 42, thereby greatly improving the installation stability of the wall panel 3.

[0059] When the wall panel 3 and the keel 2 are impacted by gravity and lateral airflow, the second bolt 52 slides in the horizontal waist-shaped hole 62. At this time, the first bolt 51 abuts against the wall of the vertical waist-shaped hole 61 to transmit power to the first connecting plate 41, so that the force acts on the web of the H-shaped steel beam 11, which greatly reduces the possibility of twisting of the first connecting plate 41 and greatly improves the installation stability of the wall panel 3.

[0060] The implementation principle of a curtain wall node connection structure in the first embodiment of the present application is:

[0061] When installing the curtain wall, first install the fixed support frame 1 on the roof, then install the keel 2, and finally install the wall panel 3 in the installation cavity 21 of the keel 2.

[0062] Embodiment 2

[0063] The difference between the second embodiment of the present application and the first embodiment is that: Figure 4 and Figure 5 The first connecting plate 41 and the second connecting plate 42 are respectively provided with a linkage plate 7, and a clamping groove 721 is formed on the linkage plate 7. The shape of the clamping groove 721 is adapted to the bolt head of the connecting bolt 5, and when the connecting bolt 5 abuts the connecting plate 4, the connecting bolt 5 can be aligned with the clamping groove 721. The number of the clamping grooves 721 is equal to the number of the connecting bolts 5 that are in the same straight line and penetrate the same connecting plate 4, and the bolt heads of the connecting bolts 5 are clamped into the clamping grooves 721.

[0064] The implementation principle of a curtain wall node connection structure in the second embodiment of the present application is:

[0065] When the connection bolts 5 are installed, the bolt heads of the connection bolts 5 are inserted into the slots 721 of the corresponding linkage plates 7. At this time, the linkage plates 7 realize the linkage of the connection bolts 5 in the same group, reducing the possibility of the connection bolts 5 becoming loose or falling off.

[0066] Embodiment 3

[0067] The difference between the third embodiment of the present application and the second embodiment is that: Figure 5 and Figure 6 The linkage plate 7 includes a plate body 71 , a mounting block 72 and a retaining ring 73 .

[0068] The mounting block 72 is a cylindrical block structure, and mounting holes 711 are formed on the plate body 71. The number of mounting holes 711 is equal to the number of connecting bolts 5 that are in the same straight line and penetrate the same connecting plate 4. The depth of the mounting holes 711 is greater than the thickness of the mounting block 72. The mounting block 72 corresponds to the mounting holes 711 one by one, and the outer peripheral side of the mounting block 72 is threadedly connected to the peripheral hole wall of the mounting hole 711.

[0069] The clamping groove 721 is formed on the mounting block 72, the retaining ring 73 corresponds to the mounting hole 711 one by one, the retaining ring 73 is threadedly connected to the plate body 71 and is located in the mounting hole 711, and the retaining ring 73 is located on the side of the mounting block 72 away from the connecting plate 4. The retaining ring 73 abuts against the side of the mounting block 72 away from the connecting plate 4, and when the connecting bolt 5 is loose and drives the mounting block 72 to rotate, the retaining ring 73 limits the rotation of the mounting block 72, and limits the loosening and falling off of the connecting bolt 5.

[0070] The implementation principle of a curtain wall node connection structure in the third embodiment of the present application is:

[0071] When the first bolt 51 is threadedly connected to the keel 2, the mounting block 72 on the plate body 71 corresponding to the first connecting plate 41 is rotated so that the slot 721 is aligned with the bolt head of the first bolt 51, and then the bolt head of the first bolt 51 is inserted into the slot 721, and then the retaining ring 73 is installed in the mounting hole 711 until the retaining ring 73 abuts against the side of the mounting block 72 away from the first connecting plate 41. When the first bolt 51 is loose, the bolt head of the first bolt 51 drives the mounting block 72 to rotate away from the first connecting plate 41. At this time, the retaining ring 73 restricts the mounting block 72 from being away from the first connecting plate 41, reducing the possibility of the first bolt 51 being loose or falling off. According to the same steps, after the second bolt 52 is threadedly connected to the fixing plate 111, the adjacent linkage plate 7 is installed to reduce the possibility of the second bolt 52 being loose or falling off.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
