Description

Technical Field

[0001] The utility model relates to the technical field of curtain walls, in particular to a component-type glass curtain wall keel insert connection structure. Background Art

[0002] Curtain wall is an external protective structure hung on the facade of a building. It plays the role of thermal insulation and decoration. It is widely favored by designers because of its advantages such as light weight, high rigidity, stable quality and good decorative effect. The building curtain wall is mainly composed of panels and supporting structure systems. Not only does it require the curtain wall structure system to have a certain ability to resist deformation relative to the main structure, but it also requires that the load borne by the facade enclosure structure system can be well transferred to the main structure.

[0003] In actual projects, the traditional installation method of the keel insert is to first insert the insert into the keel, fix it with bolts, and then insert the exposed part of the insert end into the adjacent keel. At present, the keel and insert are usually made of aluminum alloy profiles, which will not only bend and twist to a certain extent during the extrusion process, but also be prone to shear failure at the end of the insert, which often occurs earlier than the keel profile; at the same time, the beams and columns in the curtain wall are the main supporting components of the entire curtain wall system, and the force is independent of the main structure. Their strength and stiffness directly affect the bearing performance of the overall structure of the curtain wall. When the insert is damaged, the columns and beams will bear the lateral wind load and the deadweight of the vertical glass panels alone. Under long-term repeated loads, the bearing capacity at the connection node will be significantly reduced, and the columns and beams will deform and twist, which will directly affect the integrity and reliability of the curtain wall supporting structure system.

[0004] Chinese patent application number CN201220573795.1 discloses a novel curtain wall beam connection structure, including a column, a beam, a bolt assembly, a plug, and a screw. The column is provided with a groove on the curtain wall panel side, and two upper and lower bolt holes are provided at the position where the beam is connected, and the bolt holes correspond to the threaded holes on the plug and are connected to the groove; the beam is a closed-cavity aluminum profile; the bolt assembly passes through the bolt hole on the column through the groove position on the column to fix the plug to the side of the column; the plug is provided with a threaded hole, the position of which corresponds to the bolt hole on the column, and its shape matches the inner cavity of the beam; the screw is fixed on the beam and penetrates the inner wall of the beam, and its function is to control the depth of the plug inserted into the beam. There is no effective and reliable connection between the beams, columns and inserts in this structure. They are fixed only by bolts and welding. The node strength and structural integrity are obviously insufficient. Bolt holes are opened in the non-load-bearing area in the middle of the column that contacts the cover plate and the pressure plate, which may easily cause problems such as bolt falling off, keel deformation, glass panel falling off and beam twisting.

[0005] Chinese patent application number CN202122715667.8 discloses a plug for front and rear staggered keels of curtain walls, comprising a socket frame extending in the vertical direction, and the side walls of the socket frame are respectively provided with front and rear left and right support bars, the lower half of the left support bar is provided with a left protruding structure, and the upper half of the right support bar is provided with a right protruding structure; the lower part of the front and rear support bars, the left protruding structure and the lower part of the right support bar constitute a lower support structure adapted to the inner cavity of the lower curtain wall column; the upper part of the front and rear support bars and the left support bar and the right protruding structure constitute an upper support structure adapted to the inner cavity of the upper curtain wall column. In this structure, because the plug is a front-to-back staggered structure, it may cause uneven force distribution and excessive displacement at the contact position of the end of the column plug in the application, and the structure is too peculiar in shape, which also leads to the need to use a specific molding template when it is prefabricated in the factory, which increases the cost accordingly.

[0006] Therefore, in view of the problems existing in the connection nodes of traditional building curtain walls, such as bolt falling off, keel deformation, and cracks and wear on the ends of the core and the column, there is an urgent need for a component-type glass curtain wall keel core connection structure, which ensures that the core ends and the connections between the curtain wall beams and columns have sufficient shear strength, effectively improving the bearing capacity of the connections between the components in the curtain wall supporting structure system as well as the integrity and stability of the structure. Utility Model Content

[0007] Aiming at the problems of bolt falling off, keel deformation, and cracks and wear on the ends of the inserts and columns in the connection nodes of traditional building curtain walls, the utility model combines the stress characteristics of the curtain wall support structure to propose a connection node structure suitable for component-type building curtain walls. This connection node structure has good integrity, high strength at the node, strong bearing capacity, and good deformation resistance.

[0008] In order to achieve the purpose of the utility model, the technical solution adopted is: a component-type glass curtain wall keel core plug connection structure, including a core, a curtain wall keel is plugged into the core, a transition component is also installed on the curtain wall keel, and a post-embedded part for fixing on the main structure is installed on the transition component; the curtain wall keel also has a socket, and a pin assembly is also installed on the side of the core, and the pin assembly has a spring pin that can be inserted into or withdrawn from the socket.

[0009] Furthermore, the adapter assembly includes an adapter and through bolts, the adapter extends vertically to the rear of the curtain wall keel, and the through bolts fix the adapter, the curtain wall keel, and the insert together.

[0010] Furthermore, an elastic gasket is installed between the adapter and the curtain wall keel.

[0011] Furthermore, the front end of the adapter is also covered with an end cover.

[0012] Furthermore, the post-embedded component includes an embedded plate fixed to the rear end of the adapter group, and the embedded plate has a plurality of anchor bolts.

[0013] Furthermore, the post-embedded part also includes a reinforcing angle plate welded together on the embedded plate and the adapter assembly.

[0014] Furthermore, the latch assembly includes a mounting block, a slide groove extending toward the socket is formed on the mounting block, the spring latch is slidably mounted in the slide groove, and a return spring is installed between the spring latch and the bottom of the slide groove.

[0015] Furthermore, the latch assembly also includes a box body, the mounting block is fixed in the box body, and the box body is also provided with a latch hole for the spring latch to pass through; a lever is also installed on the spring latch, and the box body is also provided with a lever hole for the lever to move, and the lever passes through the lever hole and extends outward.

[0016] Furthermore, the latch assembly also includes a front fastening bolt for fixing the mounting block in the box body.

[0017] Furthermore, the box body comprises a front cap body and a rear cap body, the mounting block is fixed on the front cap body; the rear cap body is also provided with a rear fastening bolt which is locked and fixed with the insert.

[0018] Furthermore, the rear cover cap body also has a mounting groove that cooperates with the plug core.

[0019] Furthermore, there are multiple curtain wall keels and adapter assemblies, and the multiple curtain wall keels are arranged in a "cross" shape, and the adapter assembly is installed at the corner formed by two adjacent curtain wall keels.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model has reliable force and can effectively reduce the error in the installation process of the keel. At the same time, it avoids the stress concentration on the end of the core in the traditional technical solution. Under extreme conditions, the end is prematurely damaged, resulting in excessive deformation of the keel and torsion of the beam, thereby affecting the safety of the overall structure.

[0022] 2. In the utility model, the adapter is fixed to the curtain wall keel by contact. Compared with the traditional L-shaped adapter plate and U-shaped channel steel adapter, the adapter assembly and the curtain wall keel are connected by through bolts, which not only increases the contact area between the adapter and the curtain wall keel, but also avoids the problem of reduced bearing capacity of the connection due to the degradation of weld quality caused by the long service time of the component in the later period; at the same time, in the utility model, the adapter is fixed to the embedded plate, the end is strengthened by welding and the reinforcing angle plate is used to ensure that the curtain wall keel can be better transmitted to the main structure through the adapter assembly.

[0023] 3. The utility model is easy to install and disassemble, and has a fast construction speed. At the same time, it avoids the use of excessive welding operations. Most of the assembly process has been completed during prefabrication in the factory. During on-site installation, only simple bolt fixing is required to achieve the docking of the adapter and the curtain wall keel. It is also more convenient to repair and replace local components in the later stage, effectively avoiding the increase in cost due to large-scale demolition during later maintenance.

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It is to be understood that the specific implementation examples described herein are only used to explain the relevant content, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0044] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] like Figure 1 , Figure 2 As shown, the utility model provides a component-type glass curtain wall keel core plug connection structure, including a core plug 5, a curtain wall keel 3, a transition assembly 2 and a post-embedded part 1, the core plug 5 and the curtain wall keel 3 are both made of one-piece aluminum alloy, the core plug 5 has plug-in ends extending in four directions respectively, and the four plug-in ends on the core plug 5 are all plugged with curtain wall keels 3, that is, the four curtain wall keels 3 are in a "cross" shape, two curtain wall keels 3 are on the same vertical line, the other two curtain wall keels 3 are on the same horizontal line, and a right angle is formed between two adjacent curtain wall keels 3, and the curtain wall is fixed on the four curtain wall keels 3 together.

[0046] There are four adapter assemblies 2, which are respectively installed at four right angles formed by four curtain wall keels 3. The axial direction of the adapter assemblies 2 is perpendicular to the axial direction of the curtain wall keels 3. Specifically, when the curtain wall needs to be installed, the curtain wall is fixed on the four curtain wall keels 3, that is, the four curtain wall keels 3 are parallel to the surface of the main structure, and the adapter assemblies 2 extend vertically from the curtain wall keels 3 to the surface of the main structure. Each adapter assembly 2 is provided with a post-embedded part 1 at one end away from the curtain wall keel 3. The utility model fixes it to the main structure through the post-embedded part 1 during installation.

[0047] In the present invention, when one curtain wall keel 3, two curtain wall keels 3, or three curtain wall keels 3 can meet the requirements of curtain wall installation, the curtain wall keels 3 in the present invention can also be only one, two, or three. In this case, one, two, or three adapter components 2 can also be set according to the selection. When the number of right angles formed by multiple curtain wall keels 3 is less than the number of adapter components 2, the redundant adapter components 2 do not need to be installed in the right angle formed between two adjacent curtain wall keels 3, and the redundant adapter components 2 can be directly fixed to the plug-in end and the plug core 5 of the curtain wall keel 3.

[0048] like Figure 4 As shown, one end of the curtain wall keel 3 and the plug core 5 for plugging is also provided with a socket 301, and the depth direction of the socket 301 is consistent with the axial direction of the curtain wall keel 3; the plug core 5 is also installed with a latch assembly 4, and the latch assembly 4 has a spring latch 4032 that can be extended or retracted. After the curtain wall keel 3 is inserted into the plug core 5, the spring latch 4032 can be extended and inserted into the socket 301 on the curtain wall keel 3, and the spring latch 4032 can also be retracted and withdrawn from the socket 301 on the curtain wall keel 3, so that the plug core 5 and the curtain wall keel 3 are connected for the second time.

[0049] In the present invention, since there are four curtain wall keels 3, the spring latches 4032 in the present invention also need to be four. To ensure that the spring latches 4032 can be normally contracted, the four spring latches 4032 can be respectively arranged in two latch assemblies 4, that is, there are two latch assemblies 4 in the present invention. At this time, the two latch assemblies 4 are respectively installed on both sides of the plug core 5, and there are two spring latches 4032 in each latch assembly 4, so that the four spring latches 4032 correspond to four curtain wall keels 3. Of course, if there is enough space in one latch assembly 4 to arrange four spring latches 4032, only one latch assembly 4 can be arranged, and the four spring latches 4032 can be arranged together in the same latch assembly 4.

[0050] like Figure 3 As shown, the adapter assembly 2 includes an adapter 201, which extends vertically to the rear of the curtain wall keel 3, that is, when the curtain wall is installed, the adapter 201 extends to the main structure. In the utility model, the adapter 201 is a 40mm×40mm×200mm aluminum alloy square tube with a wall thickness of 3mm and a weld grade of grade III. For grade III welds, the diameter is allowed to be ≤0.4t per 50mm length of weld, and there are 2 pores of ≤3mm, and the pore spacing is ≤6 times the aperture; at the same time, in order to prevent cracks from occurring, appropriate welding process parameters and welding procedures should be selected, avoid using high current, do not suddenly turn off the flame, the weld joint should overlap 10 to 15mm, and it is not allowed to move or knock the weldment during welding.

[0051] Since aluminum profiles are very easy to oxidize in the air and during welding, aluminum oxide with a high melting point and very stable is generated, which seriously affects the welding quality. Therefore, before welding aluminum profiles, chemical or mechanical methods are required to strictly clean the surface to remove the surface oxide film, and at the same time, strengthen protection during the welding process to prevent oxidation. When tungsten inert gas arc welding, it is recommended to use AC power to remove the oxide film through the "cathode cleaning" effect. When gas welding, a flux that removes the oxide film can be used.

[0052] When the adapter 201 is installed, the two surfaces of the adapter 201 are respectively fitted with two adjacent vertically arranged curtain wall keels 3. The end of the adapter 201 connected to the curtain wall keel 3 has a plurality of through bolt holes 302. The through bolt holes 302 on the adapter 201 are divided into two groups. The axis direction of one group of through bolt holes 302 is consistent with the axis direction of the vertically extending curtain wall keel 3, and the axis direction of the other group of through bolt holes 302 is consistent with the axis direction of the horizontally extending curtain wall keel 3. At the same time, the horizontally extending curtain wall keel 3, the vertically extending curtain wall keel 3 and the plug-in end of the plug core 5 also have through bolt holes 302. When the adapter 201 is installed, the through bolts 202 pass through the through bolt holes 302 on the adapter 201, the curtain wall keel 3 and the plug core 5, so that the adapter 201, the curtain wall keel 3 and the plug core 5 are fixed together.

[0053] In order to prevent the adapter 201, the curtain wall keel 3 and the insert 5 from rotating relative to each other after being fixed together, an elastic gasket is installed between the adapter 201 and the curtain wall keel 3, and the elastic gasket also has a through hole for the through bolt 202 to pass through. The elastic gasket can increase the friction between the adapter 201 and the curtain wall keel 3, so that the through bolt 202 can be fixed more firmly after being tightened, thereby preventing the through bolt 202 from loosening as much as possible.

[0054] The front end of the adapter 201 is also covered with an end cover 203, which can not only seal the adapter 201 to prevent rainwater from entering the adapter 201 and causing corrosion of the adapter 201 over a long period of time; at the same time, the front end of the adapter 201 is covered by the end cover 203 to prevent the curtain wall from being scratched due to burrs on the end face of the adapter 201 during installation.

[0055] In the present utility model, since there are four adapter assemblies 2, there are also four post-embedded parts 1 in the present utility model, and the four post-embedded parts 1 are fixed one by one to the four adapter assemblies 2. The post-embedded parts 1 include an embedded plate 101, which is in the shape of a rectangular plate, and the embedded plate 101 is welded and fixed to the extended end of the adapter 201; at the same time, the embedded plate 101 also has a plurality of anchor bolts 102, and the plurality of anchor bolts 102 are all chemical anchor bolts 102, and the plurality of anchor bolts 102 are evenly arranged along the edge of the embedded plate 101. When the post-embedded parts 1 need to be fixed to the main structure, the embedded plate 101 is tightly attached to the main structure, and the anchor bolts 102 are implanted into the building matrix, so that the embedded plate 101 is fixed to the main structure, and finally the present utility model is fixed to the main structure.

[0056] In order to strengthen the integrity of the structure, the post-embedded component 1 also includes a plurality of reinforcing angle plates 103. The reinforcing angle plates 103 are triangular in shape. One side of the reinforcing angle plates 103 is welded to the embedded plate 101, and the other side of the reinforcing angle plates 103 is welded to the adapter 201, so that the structure between the post-embedded component 1 and the adapter assembly 2 is more solid, and the curtain wall is better stabilized after being installed together on a plurality of curtain wall keels 3.

[0057] like Figure 5 As shown, the latch assembly 4 includes a mounting block 403, which is square. When the four curtain wall keels 3 are all plugged into the plug core 5, the plug ends of the four curtain wall keels 3 surround the two sides of the plug core 5 to form a square groove, and the mounting block 403 is installed in the square groove; the mounting block 403 is provided with two slide grooves 4031, the two slide grooves 4031 are located on the same straight line, and the sockets 301 on the two curtain wall keels 3 in the vertical direction correspond to the two slide grooves 4031 on the mounting block 403, or the sockets 301 on the two curtain wall keels 3 in the horizontal direction correspond to the two slide grooves 4031 on the mounting block 403. The spring latch 4032 is slidably installed in the slide groove 4031, and a return spring 4033 is installed between the spring latch 4032 and the bottom of the slide groove 4031. When the spring latch 4032 is pushed to slide into the slide groove 4031, the spring latch 4032 withdraws from the socket 301 and compresses the return spring 4033; when the spring latch 4032 needs to be inserted into the socket 301, the return spring 4033 can be pushed by its own elastic force.

[0058] As another example, when the spring latch 4032 can be normally inserted into or withdrawn from the socket 301, the slide groove 4031 on the mounting block 403 can also be arranged in an L shape. At this time, a spring latch 4032 on the mounting block 403 corresponds to the socket 301 on the vertically extending curtain wall keel 3, and another spring latch 4032 on the mounting block 403 corresponds to the socket 301 on the horizontally extending curtain wall keel 3.

[0059] The latch assembly 4 also includes a box body, and the mounting block 403 is fixed in the box body. In order to ensure that the spring latch 4032 can be normally inserted into the socket 301 or the spring latch 4032 can be normally returned to the slide groove 4031, the box body is also provided with a latch hole 4011 corresponding to the spring latch 4032. Since there are two spring latches 4032 on the mounting block 403, there are also two latch holes 4011 on the box body. In order to facilitate the toggling of the spring latch 4032, a lever 4034 is also provided on the spring latch 4032, and the box body is also provided with lever holes 4012 corresponding to the two slide grooves 4031, the axis direction of the lever hole 4012 is consistent with the axis direction of the slide groove 4031, the length of the lever hole 4012 is not less than the sliding stroke of the spring latch 4032, and the lever 4034 penetrates the lever hole 4012 and extends outward. When the spring latch 4032 needs to be moved, the lever 4034 can be directly moved, making the movement of the spring latch 4032 more convenient.

[0060] The latch assembly 4 also includes front fastening bolts 4013 for fixing the mounting block 403 in the box body. There are four front fastening bolts 4013, which are respectively located at four right angles of the box body, so that the mounting block 403 is more firmly installed. In the present utility model, after the mounting block 403 is installed in the box body, the front and back surfaces of the mounting block 403 are both in contact with the inner wall of the box body. Therefore, after the mounting block 403 is installed in the box body, the inner wall of the box body forms a limiting surface, so that the spring latch 4032 will not be separated from the slide groove 4031 during the reciprocating sliding process along the slide groove 4031.

[0061] like Figure 6 , Figure 7 As shown, the box body includes a front cover cap body 401 and a rear cover cap body 402, the mounting block 403 is fixed on the front cover cap body 401, and the latch hole 4011 and the lever hole 4012 are both located on the front cover cap body 401, and the front cover cap body 401 and the rear cover cap body 402 are buckled together to form the box body; the rear cover cap body 402 is also provided with rear fastening bolts 4022 that are locked and fixed with the insert 5, and there are four rear fastening bolts 4022, which are located at four right angles of the rear cover cap body 402, so that the installation of the box body is more stable.

[0062] The rear cap body 402 also has an installation groove 4021 that cooperates with the ferrule 5. When installing the rear cap body 402, the rear cap body 402 is pressed to make the protrusion on the ferrule 5 engage with the installation groove 4021, so that the installation position accuracy of the rear cap body 402 is higher, making the installation of the rear cap body 402 faster and more convenient.

[0063] In the present invention, when assembling the latch assembly 4, the lever 4034 is aligned with the lever hole 4012 on the front cap body 401, the spring latch 4032 is slid to the latch hole 4011 and popped out, and the mounting block 403 is fixed to the front cap body 401 by the front fastening bolt 4013; finally, the rear cap body 402 is fixed to the plug core 5 by the rear fastening bolt 4022, and the assembled front cap body 401 is placed on the rear cap body 402. When in use, the lever 4034 is pressed up and down at the same time to shrink the spring latch 4032, and when the socket 301 corresponds to the latch hole 4011, the lever 4034 is released, and the reset spring 4033 pushes the spring latch 4032 to extend into the socket 301 on the curtain wall keel 3.

[0064] During the factory manufacturing process, the utility model can adopt an extrusion molding process to integrally mold the insert 5 and the curtain wall keel 3, and reserve bolt holes corresponding to the adapter 201 on the insert 5 and the curtain wall keel 3, thereby enhancing the integrity of the utility model.

[0065] When the utility model is used to install a curtain wall, the load on the curtain wall is transferred to the adapter assembly 2 through the curtain wall keel 3 and the insert 5, and the adapter assembly 2 transfers the load to the main structure through four groups of post-embedded parts 1. Under this structure, the supporting strength of the connection node is guaranteed; at the same time, since the adapter 201 adopts an aluminum alloy square tube, the contact area with the curtain wall keel 3 is increased, and the through bolts 202 are used to fix the adapter 201, the curtain wall keel 3 and the insert 5 together, which can effectively avoid the end of the insert 5 from being damaged earlier than the curtain wall keel 3, and effectively improve the shear strength of its end; at the same time, since the curtain wall, the curtain wall keel 3, the insert 5, and the adapter 201 are connected as a whole, the torsion phenomenon of the beam caused by external wind load under extreme conditions is effectively avoided, and the stability of the supporting structure system is improved.

[0066] In the present invention, after the curtain wall keel 3, the insert 5 and the adapter 201 are assembled, since the front cover 203 of the adapter 201 is provided with an end cover 203, the two sides of the insert 5 are installed with latch assemblies 4, thereby effectively preventing the insert 5 from being exposed.

[0067] In the present utility model, when installing the curtain wall keel 3 and the adapter 201, the deviation must be strictly controlled to ensure that the deviation of the elevation of the curtain wall keel 3 in the vertical direction is less than or equal to 3mm, and the front-to-back and left-to-right deviations of the axis of the curtain wall keel 3 are both less than or equal to 3mm; at the same time, after the installation of two adjacent curtain wall keels 3 is completed, the deviation is no more than 3mm, the distance deviation is no more than 2mm, and the maximum elevation difference between the curtain wall keels 3 on the same layer shall not be greater than 5mm.

[0068] Before installing the rear embedded parts 1, check the flatness of the main structure concrete surface. If there is an uneven concrete surface, chisel or use micro-expansion cement to remedy it. Ensure that the contact area between the embedded plate 101 and the concrete structure surface is not less than 70% before installation. Check the deviation of the embedded plate 101. The upper, lower, left and right deviation values ​​should not exceed plus or minus 45mm. The embedded plate 101 that exceeds the tolerance must be properly processed. The processing method is as follows: use a steel plate of the same thickness and material as the embedded plate 101, weld one end to the embedded plate 101, the weld height is greater than or equal to 7mm, and the weld is a continuous peripheral seam. The other end is connected with 2 M12*160 building anchor bolts 102.

[0069] In the present utility model, the anchor bolts 102 on the buried plate 101 are all M12*160mm anchor bolts 102. Before inserting the anchor bolts 102, the hole cleaning and pull-out test are required. In addition, the distance between the anchor bolts 102 and the edge of the main structure should not be less than 85mm. When drilling holes, when encountering steel bars in the main structure, the steel bar positions should be staggered and other hole points should be selected. The abandoned bolt holes on the main structure should be filled and leveled with micro-expansion cement. If the steel bars on the main structure cannot be avoided, holes can be drilled next to the buried plate 101, and a 50mm×50mm×8mm (or 50mm×80mm×8mm) galvanized connecting plate can be installed. The connecting plate is welded to the buried plate 101, and three-sided welding is performed, and the weld length is not less than 50mm.

[0070] During on-site construction, the utility model only needs to assemble the adapter assembly 2 with the curtain wall keel 3 and install the post-embedded part 1, which not only greatly improves the construction speed, but also avoids excessive welding operations and simplifies the installation process; it also ensures that it is more convenient to replace and repair local components in the later stage, and prolongs the life cycle of the structural system. The adapter assembly 2 used in the utility model increases the contact area with the curtain wall keel 3 and improves the shear strength of the end of the structure; in addition, the utility model not only ensures that the structure has sufficient strength and rigidity, but also improves the integrity and stability of the structure.
