Description

Technical Field

[0001] The present application relates to the technical field of edge-sealed secondary beam reinforcement, and in particular to a tower crane-attached edge-sealed secondary beam reinforcement device. Background Art

[0002] With the development of the construction industry, high-rise building structures are widely used. In the construction process of high-rise buildings, tower cranes are an indispensable equipment as an important means of transportation. When the tower crane is used at a height exceeding the independent height, the tower crane attachment device needs to be fixed on the building. However, with the flexibility of tower crane layout, higher requirements are placed on the selection of attachment points. Different attachment points have different effects on the main structure.

[0003] In high-rise buildings, both ends of the edge-sealing secondary beam are connected to the shear wall through cantilever beams. The load range of the edge-sealing secondary beam is small, and the cross-section and reinforcement are relatively small during design. The tower crane attached edge-sealing secondary beam will generate a large out-of-plane horizontal force on the edge-sealing secondary beam, and the horizontal shear capacity of the edge-sealing secondary beam is low, and the safety of the structure cannot be guaranteed. During the implementation process, the edge-sealing secondary beam needs to be reinforced to ensure the safety of the structure. The current method for reinforcing the edge-sealing secondary beam is to set a hidden support in the floor slab to reinforce the edge-sealing secondary beam so that the edge-sealing secondary beam has a strong horizontal shear capacity. However, this method is not applicable to the case where the edge-sealing secondary beam without a floor slab is attached to the tower crane rod. Utility Model Content

[0004] In order to improve the problem that the horizontal shear resistance of the edge-sealed secondary beam without a floor slab is low, resulting in poor safety of the edge-sealed secondary beam attached to the tower crane, the present application provides a reinforcement device for the edge-sealed secondary beam attached to the tower crane.

[0005] The present application provides a tower crane secondary beam reinforcement device with edge banding, which adopts the following technical solution:

[0009] Embedded parts are pre-installed on the shear wall and connected to one end of the diagonal brace.

[0010] Furthermore, the diagonal bracing rods are obliquely arranged between the edge sealing secondary beam and the shear wall, and the edge sealing secondary beam, the shear wall and the diagonal bracing rods are enclosed to form a triangle.

[0011] Furthermore, the reinforcing plate is configured as an integrally formed U-shaped plate, the U-shaped plate is clamped and covered on the edge sealing secondary beam, and a fastening bolt assembly for clamping the U-shaped plate on the edge sealing secondary beam is provided at the opening of the U-shaped plate.

[0012] Furthermore, both ends of the diagonal bracing rod are hinged with connecting plates, one of which is fixedly connected to the U-shaped plate, and the other is fixedly connected to the embedded part.

[0013] Furthermore, a connecting head is provided on the embedded part, the connecting head protrudes from the wall surface of the shear wall, and a connecting plate at one end of the diagonal bracing rod is fixedly connected to the connecting head.

[0014] Furthermore, a card slot is provided on the connecting head, and a card plate is fixed on one of the connecting plates.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present application embodiment discloses a tower crane secondary beam reinforcement device with edge banding. Figure 1 , Figure 2 and Figure 3A tower crane attached edge-sealed secondary beam reinforcement device is arranged between the edge-sealed secondary beam 9 and the shear wall 10, and the two ends of the edge-sealed secondary beam 9 are respectively connected to the shear walls 10 on both sides; and the reinforcement device includes a reinforcing plate, a diagonal brace 11 and an embedded part 12, the reinforcing plate is fixedly mounted on the edge-sealed secondary beam 9, and a connecting part 8 for connecting the tower crane 13 is fixed on the reinforcing plate, and the connecting part 8 is specifically configured as an ear plate hinged to the tower crane 13. Two embedded parts 12 are provided, and the two embedded parts 12 are respectively embedded in the shear walls 10 at the two ends of the edge-sealed secondary beam 9, and the shear wall 10 is also provided with a reinforcing bolt assembly 7 for reinforcing the embedded parts 12, the bolts of the reinforcing bolt assembly 7 pass through the shear wall 10 and the embedded parts 12, and then the embedded parts 12 are pressed and fixed to the shear wall 10 through the nuts at both ends, so that the embedded parts 12 are stably fixed to the shear wall 10. There are also two diagonal braces 11, which correspond to the two embedded parts 12 one by one. The diagonal braces 11 are H-shaped steels with strong supporting capacity. One end of the diagonal brace 11 is connected to the reinforcing plate, and the other end is connected to the embedded part 12 on the shear wall 10, so that the edge-sealing secondary beam 9, the shear wall 10 and the diagonal brace 11 are enclosed to form a stable triangular structure. When the edge-sealing secondary beam 9 needs to be reinforced, the diagonal brace 11 can be tilted between the shear wall 10 and the edge-sealing secondary beam 9, so that the reinforcing plate on the edge-sealing secondary beam 9 is connected to the embedded parts 12 on the shear walls 10 on both sides through the two diagonal braces 11. Under the action of the two diagonal braces 11, the horizontal force of the tower crane 13 on the edge-sealing secondary beam 9 can be transmitted to the shear wall 10, which guarantees the stability and safety of the edge-sealing secondary beam 9 to a certain extent, improves the horizontal shear resistance of the edge-sealing secondary beam 9, and enables the tower crane 13 to be stably attached to the edge-sealing secondary beam 9.

[0030] When installing the reinforcing plate, in order to avoid damage to the main structure of the edge sealing secondary beam 9, thereby affecting the horizontal shear resistance of the edge sealing secondary beam 9, Figure 1 and Figure 2The reinforcing plate is made of steel, and the reinforcing plate is set to an integrally formed U-shaped plate 1 structure. The U-shaped plate 1 is clamped and covered on the edge-sealing secondary beam 9, so that one side wall of the U-shaped plate 1 is located on the inner side of the edge-sealing secondary beam 9 and connected to the diagonal brace 11, and the other side wall of the U-shaped plate 1 is located on the outer side of the edge-sealing secondary beam 9 and connected to the tower crane 13. A fastening bolt assembly 2 for clamping the U-shaped plate 1 on the edge-sealing secondary beam 9 is provided at the opening of the U-shaped plate 1. Two fastening bolt assemblies 2 are provided, and the two fastening bolt assemblies 2 are installed on the U-shaped plate 1 at intervals. The screws in the fastening bolt assemblies 2 are sequentially passed through the side walls on both sides of the U-shaped plate 1, and the side walls of the screws are in contact with the surface of the edge-sealing secondary beam 9, so that the U-shaped plate 1 and the screws are enclosed to form a closed structure, ensuring that the U-shaped plate 1 is not easy to fall off from the edge-sealing secondary beam 9. Both ends of the screw rod are threaded with nuts. By tightening the two nuts, the nuts press the side walls of the U-shaped plate 1 against the edge-sealing secondary beam 9, which not only ensures the stability of the U-shaped plate 1 when installed on the edge-sealing secondary beam 9, but also prevents the U-shaped plate 1 from being deformed when subjected to the horizontal force of the diagonal brace rod 11 or the tower crane 13.

[0031] Considering the stability of the connection between the U-shaped plate 1 and the diagonal brace 11, and the embedded part 12 and the diagonal brace 11, in the embodiment of the present application, the connection between the U-shaped plate 1 and the diagonal brace 11, and the connection between the embedded part 12 and the diagonal brace 11 are all welded. Since the diagonal brace 11 is tilted between the U-shaped plate 1 and the embedded part 12, in order to increase the welding area between the diagonal brace 11 and the U-shaped plate 1, and between the diagonal brace 11 and the embedded part 12, the diagonal brace 11 is welded. Figure 1 , Figure 2 and Figure 3 , both ends of the diagonal brace 11 are hinged with connecting plates 3, the connecting plates 3 are made of steel, and the hinge shaft 14 for hingedly connecting the connecting plates 3 and the diagonal brace 11 is also made of steel, and the length direction of the hinge shaft 14 is perpendicular to the length direction of the edge sealing secondary beam 9. By rotating the connecting plates 3 at both ends of the diagonal brace 11, one of the connecting plates 3 is stably welded to the U-shaped plate 1, and the other connecting plate 3 is welded to the stable embedded part 12, thereby ensuring that the diagonal brace 11 can stably transfer the horizontal force of the tower crane 13 on the edge sealing secondary beam 9 to the shear wall 10.

[0032] After the tower crane 13 is attached, the diagonal brace 11 needs to be removed from the embedded part 12, and the embedded part 12 is embedded in the shear wall 10. In order not to damage the structure of the shear wall 10 when removing the diagonal brace 11, Figure 1 and Figure 3, the embedded part 12 is provided with a connector 4, which is also made of steel and is integrally formed with the embedded part 12. When the embedded part 12 is embedded in the shear wall 10, the connector 4 protrudes from the wall surface of the shear wall 10, so that the connecting plate 3 on one end of the diagonal brace 11 can be welded to the connector 4. When the diagonal brace 11 needs to be removed from the embedded part 12, the connector 4 can be cut off from the embedded part 12, and this method will not damage the integrity of the shear wall 10 structure.

[0033] In order to further improve the stability of welding between the connecting plate 3 and the connecting head 4, refer to Figure 3 , a slot 5 is provided on the connector 4, the length direction of the slot 5 is perpendicular to the length direction of the hinge shaft 14, and both ends of the slot 5 are open. There are a plurality of slots 5, and the slots 5 are arranged at intervals along the length direction of the hinge shaft 14. In addition, a plurality of card plates 6 are welded and fixed on the connecting plate 3 corresponding to the connector 4, and the card plates 6 are also made of steel. The card plates 6 correspond to the slots 5 one by one. When the connector 4 is welded and connected to the connecting plate 3, the connecting plate 3 can drive the card plates 6 to rotate on one end of the diagonal brace 11 by rotating the connecting plate 3, so that the card plates 6 can be correspondingly inserted into the slots 5, and then the card plates 6 are welded and fixed on the inner wall of the slot 5 to increase the welding area between the connecting plate 3 and the connector 4, thereby improving the stability of the welding between the connecting plate 3 and the connector 4. At the same time, the arrangement of the slot 5 and the card block enables the diagonal brace 11 to adjust its installation angle within a certain range according to the installation requirements, and also ensures that the connecting plate 3 can be stably welded and connected to the connector 4.

[0034] The implementation principle of a tower crane attached edge-sealed secondary beam reinforcement device according to the embodiment of the present application is as follows: first, two embedded parts 12 are respectively embedded in two shear walls 10, and the embedded parts 12 are fixed by reinforcing bolt assemblies 7, at which time the connector 4 on the embedded part 12 protrudes from the wall surface of the shear wall 10. Then, the U-shaped plate 1 is fixedly installed on the edge-sealed secondary beam 9 by tightening the bolt assembly 2. Then, the connecting plate 3 on one end of the diagonal brace 11 is welded and fixed to the U-shaped plate 1, and then the diagonal brace 11 and the connecting plate 3 on the other end of the diagonal brace 11 are rotated so that the card plate 6 on the connecting plate 3 is correspondingly inserted into the card slot 5 on the connector 4, and then the card plate 6 is welded and fixed to the inner wall of the card slot 5, so that the connector 4 is stably welded and connected to the connecting plate 3. At this time, the diagonal brace 11 is tiltedly arranged between the shear wall 10 and the edge-sealed secondary beam 9, so that the edge-sealed secondary beam 9, the shear wall 10 and the diagonal brace 11 are enclosed to form a stable triangular structure. Finally, the tower crane 13 is hinged to the U-shaped plate 1 on the edge-sealing secondary beam 9 through the ear plate. Under the action of the two diagonal braces 11, the horizontal force exerted by the tower crane 13 on the edge-sealing secondary beam 9 can be transmitted to the shear wall 10, which ensures the stability and safety of the edge-sealing secondary beam 9 to a certain extent, improves the horizontal shear resistance of the edge-sealing secondary beam 9, and enables the tower crane 13 to be stably attached to the edge-sealing secondary beam 9.
