Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] As one embodiment of the present invention, such as Figures 1 to 9 As shown, the curtain wall keel embedded component with stress buffer structure of the present invention includes an embedded channel steel 1, a main keel 2, and a secondary keel 3. The main keel 2 is connected to the embedded channel steel 1 through a buffer component 4, and the secondary keel 3 is connected to the main keel 2 through a buffer component 5. Anchor bars 6 are connected to the back of the embedded channel steel 1. The anchor bars 6 are provided with a storage groove 7 that communicates with the inner side of the embedded channel steel 1. Extrusion columns 8 are slidably connected in the storage groove 7. The storage groove 7 is filled with a water-swellable material. The anchor bars 6 are circumferentially distributed with the storage column 8. The groove 7 is connected to the water-permeable hole 9. One side of the extrusion column 8 is in contact with the pull rod 10. The end of the pull rod 10 away from the extrusion column 8 is connected to the sliding column 11. The guide sleeve 12 is slidably connected to the sliding column 11. The guide sleeve 12 is provided with a guide groove 13 inside. The sliding column 11 is provided with a guide block 14 that is slidably connected to the guide groove 13. The outer side of the end of the guide sleeve 12 is connected to the positioning plate 15. The end of the positioning plate 15 away from the pull rod 10 is provided with a magnet 16. The back of the magnet 16 is provided with a snap-fit ​​part that is rotatably snapped into the guide sleeve 12.

[0036] In use, insert the pull rod 10 into the storage slot 7, and position the positioning plate 15 and the magnet 16 inside the embedded channel steel 1, so that the end of the pull rod 10 is pressed into contact with the extrusion column 8, and ensure that the magnet 16 is flush with the side of the embedded channel steel 1; then twist the positioning plate 15 90 degrees, so that the positioning plate 15 is locked inside the embedded channel steel 1. The twisted positioning plate 15 is rotated and locked with the locking piece through the guide sleeve 12, thereby ensuring the stability of the positioning plate 15 inside the embedded steel channel.

[0037] In the concrete wall pouring process, first, the magnet 16 is adsorbed on the side of the metal pouring formwork, and the magnet 16 can pull the positioning plate 15 through the rotating clamping piece, so as to ensure the stability between the embedded channel steel 1 and the metal pouring formwork; after the metal pouring formwork is supported and pouring is completed, the water in the concrete slowly enters the storage tank 7 through the water permeable hole 9, and after the water-swellable material swells after absorbing water, it can drive the extrusion column 8 to move, and by moving the extrusion column 8, the pull rod 10 is moved into the guide sleeve 12, and the guide sleeve 12 is driven to rotate by the sliding cooperation of the guide groove 13 and the guide block 14, so as to drive the positioning plate 15 to rotate; after the positioning plate 15 rotates, it no longer clamps the embedded channel steel 1, and the clamping piece no longer clamps the positioning plate 15; after the subsequent workers remove the metal pouring formwork, the magnet 16 can quickly separate from the embedded channel steel 1 together with the metal pouring formwork, thereby greatly facilitating the metal pouring formwork removal work of the workers, improving the work efficiency, and effectively reducing the workpiece damage in the metal pouring formwork removal process;

[0038] After the metal pouring formwork is removed, the positioning plate 15 can be taken out from the embedded channel steel 1; the worker can use the T-shaped bolt to connect the buffer piece one 4 with the embedded channel steel 1; the worker can also reverse the pull rod 10, make the end of the pull rod 10 in contact with the extrusion column 8 outward, and put the positioning plate 15 into the embedded channel steel 1 and rotate it by 90 degrees, rely on the positioning plate 15 to clamp the embedded channel steel 1, use the pull rod 10 to connect with the buffer piece one 4, and complete the installation of the buffer piece one 4; then connect the main keel 2 with the buffer piece one 4, then connect the buffer piece two 5 on the side of the main keel 2, and connect the auxiliary keel 3 with the buffer piece two 5 to complete the installation of the auxiliary keel 3; the subsequent curtain wall assembly can be installed on the auxiliary keel 3 to complete the installation of the curtain wall.

[0040] In use, the clamping column 17 can be inserted into the guide sleeve 12, the boss 19 passes through the notch of the annular plate one 18, the positioning plate 15 is twisted by 90 degrees, the boss 19 avoids the axial movement of the guide sleeve 12 and the clamping column 17, so as to ensure the clamping stability of the positioning plate 15 and the clamping piece;

[0041] After the metal pouring formwork is supported and pouring is completed, the water in the concrete slowly enters the storage tank 7 through the water-permeable hole 9, and after the water-swellable material absorbs water and swells, it can drive the extrusion column 8 to move, push the pull rod 10 to move into the guide sleeve 12, and rely on the sliding cooperation of the guide groove 13 and the guide block 14 to drive the guide sleeve 12 to rotate, thereby driving the positioning plate 15 to rotate; After the positioning plate 15 rotates, the annular plate one 18 and the boss 19 correspond, the guide sleeve 12 can axially move with the clamping column 17, so that the clamping piece is no longer clamped with the boss 19; After the subsequent workers remove the metal pouring formwork, the magnet 16 and the clamping piece can be quickly separated from the embedded channel steel 1 together with the metal pouring formwork, thereby greatly facilitating the metal pouring formwork removal work of the workers, improving the work efficiency, and effectively reducing the workpiece damage during the metal pouring formwork removal process; The bushing can limit the sliding column 11 to avoid the sliding column 11 from being separated from the guide sleeve 12.

[0042] As an embodiment of the application, the extrusion column 8 is a stepped column, the end of the extrusion column 8 close to the pull rod 10 is an upper column with a smaller diameter, the outer side of the upper column is connected with a notched annular plate two 21, the inner wall of the storage tank 7 is provided with an axially arranged ridge 22, the side surface of the lower column is distributed with a sliding groove 23 in sliding cooperation with the ridge 22, the end surface of the upper column is provided with a plug-in block 24, the end surface of the pull rod 10 is provided with a plug-in groove 25 corresponding to the plug-in block 24, the end of the storage tank 7 close to the embedded channel steel 1 is provided with a limiting ring 26, and the end of the pull rod 10 away from the guide sleeve 12 is provided with a threaded structure.

[0043] In use, the worker turns the pull rod 10 so that the end of the pull rod 10 in contact with the extrusion column 8 faces outward, and places the positioning plate 15 into the embedded channel steel 1 and rotates it by 90 degrees, relying on the positioning plate 15 to clamp the embedded channel steel 1; When the positioning plate 15 is placed into the embedded channel steel 1, the guide sleeve 12 can be sleeved on the upper column of the extrusion column 8, and the boss 19 passes through the notch of the annular plate two 21, and in the process of the positioning plate 15 being twisted by 90 degrees, the boss 19 is clamped with the annular plate two 21, thereby avoiding axial movement of the extrusion column 8 and the guide sleeve 12; At this time, the pull rod 10 can be clamped with the embedded channel steel 1 through the positioning plate 15 on the guide sleeve 12, and can also be clamped with the extrusion column 8 through the guide sleeve 12, thereby improving the stability of the pull rod 10 and ensuring the connection strength of the pull rod 10;

[0044] The sliding fit of the convex rib 22 and the sliding groove 23 can ensure the stability of the extrusion column 8 during movement, and avoid rotation of the extrusion column 8 when the extrusion column 8 is moved by the water-swelling material; meanwhile, the insertion of the pull rod 10 into the insertion block 24 and the insertion groove 25 can avoid relative rotation between the pull rod 10 and the extrusion column 8, thereby improving the stability of the movement of the pull rod 10, so as to ensure that the pull rod 10 can drive the guide sleeve 12 to rotate under the driving of the extrusion column 8, thereby driving the positioning plate 15 to rotate; and through the cooperation of the insertion block 24 and the insertion groove 25, the pull rod 10 and the extrusion column 8 can be easily separated, thereby facilitating subsequent rotation of the pull rod 10; meanwhile, the pull rod 10 end installation nut and the buffer piece one 4 are also connected, and the installation of the buffer piece one 4 is completed.

[0045] As an embodiment of the present application, the buffer piece one 4 comprises a support shell one 27, the support shell one 27 is open towards the main keel 2, an active plate one 28 is movably connected in the support shell one 27, an elastic air bag one 29 and a damping telescopic rod 30 are connected between the active plate one 28 and the bottom of the support shell one 27, the active plate one 28 is connected with the side of the main keel 2 through bolts, and the support shell one 27 is connected with the embedded channel steel 1 through angle steel 32.

[0046] In use, the main keel 2 can be connected with the active plate one 28 through bolts; when the main keel 2 is extruded to one side of the embedded channel steel 1 under stress, the active plate one 28 can be automatically driven to move, and the elastic air bag one 29 and the damping telescopic rod 30 are compressed by the active plate one 28, so as to buffer the stress of the main keel 2, thereby improving the stability of the main keel 2 and reducing the damage of the main keel 2.

[0047] As an embodiment of the present application, the buffer piece two 5 comprises a support shell two 31, the support shell two 31 is connected with the main keel 2 through angle steel 32, the support shell two 31 is open towards the auxiliary keel 3, an active plate two 33 is movably connected in the support shell two 31, an elastic air bag two 34 and a damping telescopic rod 30 are connected between the active plate two 33 and the bottom of the support shell two 31, and the active plate two 33 is connected with the auxiliary keel 3 through bolts.

[0048] In use, the auxiliary keel 3 can be connected with the active plate two 33 through bolts; when the auxiliary keel 3 is extruded to one side of the embedded channel steel 1 under stress, the active plate two 33 can be automatically driven to move, and the elastic air bag two 34 and the damping telescopic rod 30 are compressed by the active plate two 33, so as to buffer the stress of the auxiliary keel 3, thereby improving the stability of the auxiliary keel 3 and reducing the damage of the auxiliary keel 3.

[0049] As an embodiment of the present application, the elastic air bag one 29 and the elastic air bag two 34 are connected with a gas supply pipeline with a one-way valve and a gas return pipeline with an adjusting valve.

[0050] In use, when the curtain wall on the secondary keel 3 is pressed to the side of the main keel 2 due to wind or the like, the buffer piece two 5 can be compressed, thereby compressing the elastic air bag two 34; the gas in the elastic air bag two 34 is pressed and enters the elastic air bag one 29 through the one-way valve, and part of the gas is slowly supplied back to the elastic air bag two 34 through the regulating valve; after the elastic air bag one 29 is inflated, the elastic force of the elastic air bag one 29 is increased, thereby improving the rigidity of the buffer piece one 4 and reducing the vibration of the buffer piece one 4; in this way, when the secondary keel 3 vibrates frequently, the stability of the main keel 2 is improved, the frequent vibration of the main keel 2 is reduced, and the structural stability of the main keel 2 is improved; on the contrary, for accidental vibration, such as earthquake or the like, the vibration between the wall and the main keel 2 can be absorbed by the buffer piece one 4, and the relative vibration between the main keel 2 and the secondary keel 3 can be absorbed by the buffer piece two 5, thereby improving the stability of the curtain wall structure.

[0051] As an embodiment of the present application, the inner wall of the storage tank 7 is coated with a water-soluble protective layer.

[0052] In use, the water-soluble protective layer on the inner wall of the storage tank 7 can protect the water-swelling material in the tank from moisture and impurities in the environment when it has not encountered water, thereby preventing the water-swelling material from swelling prematurely and failing; after encountering water, the protective layer dissolves, without affecting the water-swelling material from contacting water and swelling normally, thereby ensuring the timeliness and reliability of the anchoring and reinforcing function.

[0053] As an embodiment of the present application, before the concrete is poured, the water-soluble protective layer acts as a physical barrier and can tightly adhere to the inner wall of the storage tank 7, thereby isolating the water-swelling material from the external environment, avoiding the penetration of moisture in the air into the storage tank 7, preventing the water-swelling material from swelling slightly due to premature moisture absorption, and causing insufficient swelling during subsequent pouring; at the same time, the protective layer blocks impurities such as construction dust and concrete debris from entering the storage tank 7, thereby avoiding the mixing of impurities with the water-swelling material and affecting the swelling uniformity, and ensuring that the material remains dry and pure in the “ready state” before pouring.

[0054] When the concrete is poured, a large amount of water will contact the area of the storage tank 7: the water-soluble protective layer slowly dissolves after encountering water, thereby delaying the time when the water-swelling material contacts water; at the same time, the water-soluble protective layer does not produce residues during the dissolution process, and does not react with the components of the concrete, thereby avoiding negative effects on the quality of the concrete pouring; after the protective layer dissolves, the water-swelling material in the storage tank 7 can directly contact the water in the concrete, swell as designed, push the extrusion column 8 to act on the pull rod 10, thereby driving the positioning plate 15 to rotate, facilitating the separation of the positioning plate 15 from the embedded channel steel 1 after the concrete solidifies, thereby ensuring the stability of the embedded channel steel 1 connected with the metal pouring formwork when the concrete has not solidified, and facilitating the convenience of separating the magnet 16 from the positioning plate 15 after the concrete solidifies, thereby facilitating the disassembly of the metal pouring formwork.

[0055] As an embodiment of the present application, the support shell 231 is provided with a plurality of sets of support springs 35 sleeved on the damping telescopic rod 30.

[0056] In use, the support springs 35 sleeved on the damping telescopic rod 30 can cooperate with the elastic air bag 34 and the damping telescopic rod 30: the support springs 35 can share part of the load, provide auxiliary buffering when the elastic air bag 34 is insufficiently deformed under low-frequency stress, enhance the load-bearing capacity and buffering effect of the buffering member 5, and reduce the wear of the damping telescopic rod 30 and the elastic air bag 34, thereby improving the durability thereof.

[0057] In use, first, the pull rod 10 is inserted into the storage groove 7 of the anchor bar 6, so that the positioning plate 15 and the magnet 16 are located in the embedded channel steel 1, the end of the pull rod 10 is in extrusion contact with the extrusion column 8, the magnet 16 is flush with the side surface of the embedded channel steel 1, the positioning plate 15 is twisted by 90 degrees, the magnet 16 is clamped with the guide sleeve 12 through the clamping member, and the stability of the positioning plate 15 in the embedded channel steel 1 is ensured.

[0058] The magnet 16 is adsorbed on the side surface of the metal pouring formwork, the magnet 16 pulls the positioning plate 15 through the clamping member, the relative position between the embedded channel steel 1 and the formwork is ensured to be stable, and accurate positioning is provided for concrete pouring.

[0059] The water in the concrete slowly enters the storage groove 7 through the water-permeable hole 9 of the anchor bar 6, the water-soluble protective layer is dissolved in water, and the water body begins to contact the water-swelling material;

[0060] The water-swelling material absorbs water and swells, pushes the extrusion column 8 to slide along the convex rib 22 in the storage groove 7, the extrusion column 8 is linked with the insertion slot 25 of the pull rod 10 through the insertion block 24, drives the pull rod 10 to move towards the guide sleeve 12, the guide sleeve 12 is rotated through the cooperation of the guide groove 13 and the guide block 14, drives the positioning plate 15 to rotate, releases the clamping of the positioning plate 15 and the embedded channel steel 1, and the clamping member is separated from the locking.

[0061] When the metal pouring formwork is removed, the magnet 16 is separated from the embedded channel steel 1 together with the metal pouring formwork, so that the embedded channel steel 1 is prevented from being damaged in the removal process.

[0062] After the positioning plate 15 is taken out of the embedded channel steel 1, the pull rod 10 is turned over, so that the end of the pull rod 10 in contact with the extrusion column 8 faces outward, the pull rod 10 is reinserted into the embedded channel steel 1 and rotated by 90 degrees, the embedded channel steel 1 is clamped through the positioning plate 15, and the end of the pull rod 10 is connected with the buffering member 1 4 through the threaded structure (a nut can be installed on the threaded structure for fixation).

[0063] The main keel 2 is connected with the movable plate 28 of the buffer 4 by bolts, and the support shell 27 of the buffer 4 can be installed by using the threaded structure of the end of the pull rod 10 to install the nut, or can be installed by being fixed on the embedded channel steel 1 through T-shaped bolts.
