Description

Technical Field

[0001] This utility model relates to the field of curtain wall connection node technology, specifically to a buffer-type curtain wall seismic connection node. Background Technology

[0002] A buffer-type seismic connection node for curtain walls is a type of connection that uses elastic or deformable connections to allow relative movement between the curtain wall and the main building structure, thereby reducing the direct impact of seismic forces on the curtain wall and improving the durability and energy dissipation capacity of the buffer node.

[0003] Common buffer curtain walls use steel claws and connectors to connect tempered glass. Then, on the other side of the steel claws, horizontal and vertical stainless steel cables are connected. High pressure is generated by a hydraulic tensioner, which pushes the piston to apply pressure to the steel cables. With the help of an oil pressure gauge, the tension is precisely controlled to achieve the effect of fixing the curtain wall.

[0004] However, common glass curtain walls will wear down due to vibration during actual use, and some glass curtain walls need to be replaced after a certain period of time. When connecting a common single glass curtain wall, connecting bolts and steel claw structures need to be installed at the four corners. In addition, during disassembly, a level monitoring instrument is needed to monitor the tilt angle of the glass, which makes the disassembly process more complicated and affects the maintenance of the glass curtain wall. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a buffer-type seismic connection node for curtain walls, thereby improving the efficiency of replacing glass curtain walls and steel claws during maintenance and simplifying the disassembly and maintenance process.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a buffer-type curtain wall seismic connection node, including a glass curtain wall, a round cap limiting rod, a ring sleeve, a steel claw, a single cable pressure block, a steel cable, and a locking bolt. The locking bolt is movably inserted into the single cable pressure block, and the locking bolt is threaded to one side of the steel claw. Both sides of the glass curtain wall are in contact with washers, and the washers are sleeved on the round cap limiting rod. A connecting post is sleeved on the round cap limiting rod, and a clamping plate is sleeved on the connecting post. The clamping plate is fixed near the steel cable. A connecting strip is provided, and a circular plate is fixedly connected to one side of the connecting strip. A slot is provided on the side of the circular plate near the round cap limiting rod. Two through holes are provided on the bottom side of the circular plate. A pressure rod is inserted into the through holes. A limiting plate is fixedly connected to the pressure rod in the through holes. A spring is in contact with one side of the limiting plate and the spring is sleeved on the pressure rod. A pressure plate is fixedly connected to the side of the pressure rod near the slot. A strip groove is in contact with one side of the pressure plate. The strip groove is located on the round cap limiting rod and the strip groove is evenly distributed.

[0007] As a preferred technical solution of this utility model, the circular plate has hidden grooves on both sides of the slot. The hidden grooves correspond to the pressure plate. By setting the hidden grooves, it is convenient to limit and hide the plate.

[0008] As a preferred technical solution of this utility model, the circular plate is welded with a reinforcing rib on the side away from the steel cable. The reinforcing rib is made of metal. By setting the reinforcing rib, the connection effect between the circular plate, the clamping plate and the connecting strip is increased.

[0009] As a preferred technical solution of this utility model, one of the single cable pressure blocks is fixedly connected to a fixing cover on one side, and the fixing cover is far away from the glass curtain wall. A limiting groove is opened in the fixing cover, and a baffle is engaged in the limiting groove. One side of the baffle contacts one end of the locking bolt. By setting the fixing cover and the baffle, the locking bolt can be limited, reducing the bolt loosening caused by the vibration of the glass curtain wall.

[0010] As a preferred technical solution of this utility model, a recess is provided on the upper side of the limiting groove, and a rubber gasket is fixedly connected in the recess. The rubber gasket contacts the baffle. By setting the rubber gasket, the friction between the baffle and the limiting groove is increased, and the shaking of the baffle is reduced.

[0011] This utility model has the following advantages:

[0012] (1) By setting a movable pressure plate to connect the strip grooves at different positions, the connection between the round cap limit rod and the steel claw can be achieved. With the help of the connecting column and the gasket, it is easier to disassemble and replace the glass curtain wall or components, improve the disassembly efficiency, and simplify the disassembly process.

[0013] (2) By setting a detachable baffle limit locking bolt, the tightness of the connection between the locking bolt and the steel claw is maintained, the bolt loosening caused by the shaking of the glass curtain wall is reduced, and the overall safety of the glass curtain wall is improved.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figure 1-4 The diagram shows a buffer-type seismic connection node for a curtain wall, comprising a glass curtain wall 1, a round cap limiting rod 2, a ring sleeve 3, a steel claw 4, a single cable pressure block 5, a steel cable, and a locking bolt 6. The locking bolt 6 connects to the steel claw 4 and simultaneously limits two opposing single cable pressure blocks 5. The single cable pressure blocks 5 have a split structure. The locking bolt 6 is movably inserted into the single cable pressure block 5, and the locking bolt 6 is threaded to one side of the steel claw 4. Both sides of the glass curtain wall 1 are in contact with washers 7, which are made of rubber. The round cap limiting rod 2 consists of a rod and a cylindrical protrusion. The washers 7 are sleeved on the round cap limiting rod 2. A connecting post 8 is sleeved on the round cap limiting rod 2, and a retaining plate 9 is sleeved on the connecting post 8. The retaining plate 9 movably connects to the connecting post 8, facilitating the connection between the steel claw 4 and the glass curtain wall 1 and improving connection stability. A connecting strip 10 is fixedly connected to the side of the retaining plate 9 near the steel cable. A circular plate 11 is fixedly connected to one side of the glass curtain wall 1. The pressure plate 16 on the circular plate 11, together with the strip groove 18 on the round cap limiting rod 2, can provide adjustment and quickly separate the glass curtain wall 1 from the circular plate 11. A slot 12 is opened on the side of the circular plate 11 near the round cap limiting rod 2. Two through holes 13 are opened on the bottom side of the circular plate 11. A pressure rod 14 is inserted into the through hole 13. A limiting plate 15 is fixedly connected to the pressure rod 14 in the through hole 13. A spring is in contact with one side of the limiting plate 15 and the spring is sleeved on the pressure rod 14. A pressure plate 16 is fixedly connected to the side of the pressure rod 14 near the slot 12. A strip groove 18 is in contact with one side of the pressure plate 16. The strip groove 18 is located on the round cap limiting rod 2 and is evenly distributed. By setting the pressure rod 14 with an elastic structure, the pressure plate 16 extends and engages the strip groove 18 in the normal state.

[0021] The circular plate 11 has hidden grooves 17 on both sides inside the slot 12. The hidden grooves 17 correspond to the pressure plate 16. By setting the hidden grooves 17, the pressure plate 16 can be hidden. When the pressure plate 16 is squeezed, it will retract into the hidden grooves 17.

[0022] Among them, the circular plate 11 has a reinforcing rib 19 welded on the side away from the steel cable. The reinforcing rib 19 is made of metal. By setting the reinforcing rib 19, the connection effect between the card plate 9, the connecting strip 10 and the circular plate 11 can be improved, and the limiting stability can be increased.

[0023] One of the single-cable pressure blocks 5 is fixedly connected to a fixing cover 20 on one side, and the fixing cover 20 is far away from the glass curtain wall 1. A limiting groove 21 is opened in the fixing cover 20, and a baffle 22 is engaged in the limiting groove 21. One side of the baffle 22 is in contact with one end of the locking bolt 6. By setting the fixing cover 20, the limiting groove 21 and the baffle 22, the locking bolt 6 can be limited, thereby preventing the locking bolt 6 from loosening under vibration.

[0024] The upper side of the limiting groove 21 has a recess, and a rubber pad 23 is fixedly connected in the recess. The rubber pad 23 contacts the baffle 22. By setting the rubber pad 23, the friction between the baffle 22 and the limiting groove 21 is increased, and the shaking of the baffle 22 is reduced.

[0025] Working principle: When disassembling a single glass curtain wall 1 during the maintenance cycle, the preload between the hydraulic tensioner and the steel cable needs to be released (10%-20%) first, and four vacuum suction cups are set to adsorb the glass curtain wall 1. Then, the four steel claws 4 are disassembled diagonally. First, the pressure rod 14 is pulled so that the pressure plate 16 is no longer inserted into the strip groove 18. At this time, the clamping plate 9 can be disengaged from the round cap limit rod 2 by moving it. Then, the glass curtain wall 1 is no longer connected to the steel claws 4. Then, the baffle 22 is disassembled and the locking bolt 6 is removed, so that the single cable pressure block 5 is disengaged from the steel cable. Finally, the glass curtain wall 1 can be detached by the vacuum suction cups.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
