Technical Field

[0001] The utility model belongs to the technical field of construction and relates to a tower crane dismantling device, in particular to a roof crane positioning auxiliary device. Background Art

[0002] In modern urban construction, especially after the structure of a super high-rise building is capped, the removal of a boom tower crane often faces multiple challenges. These challenges mainly come from the following aspects:

[0003] 1. Structural limitations and lack of preset installation points: Super high-rise buildings usually fail to fully reserve suitable lifting facilities or interfaces during the design and construction stages for subsequent tower crane dismantling operations. This results in the need to modify the existing building structure or add temporary structures during the actual dismantling process to support the roof crane used in the dismantling operation.

[0004] 2. Safety issues: Due to the height of the tower crane and the complexity of the demolition operation, how to ensure safety during the operation has become an important issue. Any structural instability caused by emergency modification or non-standard installation may bring serious safety risks.

[0005] 3. Cost and time efficiency: In the absence of preset installation points, the construction team needs additional time and resources to build a suitable support and lifting structure, which not only increases the total cost of the project but also affects the project schedule.

[0006] 4. Technical challenges: For super high-rise buildings whose structures have been topped out, any form of structural changes or additions will face strict technical review and execution difficulties, which requires high-level engineering design and construction technology to ensure the feasibility and safety of the changes.

[0007] Therefore, in view of the above-mentioned difficulties in the dismantling of super-high-rise boom tower cranes, especially when the on-site structure has been cast and there is no pre-set interface, how to avoid adding additional structure and ensure safety has become an urgent problem that needs to be solved.

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 9 As shown, the roof crane positioning auxiliary device includes a shear wall 1 and a structural beam 7 located at different positions, the two sides of the shear wall 1 are symmetrically fixed with positioning plates 2, the positioning plates 2 on both sides are fixedly connected, the top edges of the positioning plates 2 extend upward and are flush with the top surface of the shear wall 1, the top edges of the positioning plates 2 on both sides are fixedly connected with a connecting plate 4, and a horse stool 6 is fixed on the connecting plate 4; the top surface of the structural beam 7 is fixedly attached to the hoop panel 8, the bottom surface of the structural beam 7 is fixedly attached to the hoop back plate 9, the hoop panel 8 and the hoop back plate 9 are fixedly connected, and a horse stool 2 11 is fixed on the hoop panel 8; a roof crane 12 is fixed on the horse stool 1 6 and the horse stool 2 11.

[0036] like Figures 1 to 5As shown, the shear wall 1 is penetrated with several positioning holes 1 in the horizontal direction, and the positioning plate 2 is provided with several positioning holes 2 correspondingly. The positioning holes 1 and the positioning holes 2 are connected one by one, and the transverse bolts 3 are penetrated with the positioning holes 1 and the positioning holes 2 correspondingly. The protruding ends of the transverse bolts 3 on both sides are sleeved with transverse nuts to form thread locking. Since the wall of the shear wall 1 is fixedly connected to the ground, the horse stool 1 6 is fixedly installed on the top surface of the shear wall 1. The construction of the fixed connection structure on both sides of the shear wall 1 can not only provide an installation base for the horse stool 1 6, but also improve the connection strength between the horse stool 1 6 and the shear wall 1, and provide good bearing support capacity.

[0037] The side of the connecting plate 4 extends horizontally and exceeds the positioning plate 2. The bottom surface of the connecting plate 4 and the outer surface of the positioning plate 2 are fixedly connected with the reinforcing rib plate 5, which is an inverted right-angled trapezoidal plate. The connecting plate 4 and the positioning plate 2 are combined by the reinforcing rib plate 5 to form a triangular support structure, thereby further improving the support strength and stability of the positioning plate 2 to the connecting plate 4.

[0038] The saddle 6 is fixed to the left, middle or right position of the top surface of the connecting plate 4. Since the top surface of the connecting plate 4 is not interfered by the installation of the transverse bolt 3, the saddle 6 can be adjusted accordingly within the range of the top surface of the connecting plate 4 according to the installation point of the roof crane 12, thereby facilitating the flexible installation of the roof crane 12.

[0039] like Figures 6 to 8 As shown, the two sides of the hoop panel 8 extend horizontally and exceed the structural beam 7 to form an upper edge, and the two sides of the hoop back plate 9 extend horizontally and exceed the structural beam 7 to form a lower edge. A plurality of fixing holes 1 are provided on the upper edge, and a plurality of fixing holes 2 are correspondingly provided on the lower edge. The vertical bolts 10 are correspondingly connected to the fixing holes 1 and 2, and the upper and lower protruding ends of the vertical bolts 10 are sleeved with vertical nuts to form threaded locking. Since the structural beam 7 is a suspended structure, the horse stool 2 11 is fixedly installed on the top surface of the structural beam 7. The construction of the fixed connection structure in the upper and lower spaces of the structural beam 7 can not only provide an installation base for the horse stool 2 11, but also improve the connection strength between the horse stool 2 11 and the structural beam 7, and provide good bearing support capacity.

[0040] The second horse stool 11 is fixed to the middle position of the top surface of the hoop panel 8. Because the top surface of the hoop panel 8 is interfered by the installation of the vertical bolt 10, the second horse stool 11 can only be installed in the middle of the top surface of the hoop panel 8.

[0041] like Fig. 9 As shown, the roofing crane 12 has a base 12a, on which a cross beam 12b is arranged, and the four ends of the cross beam 12b are four installation points. The four installation points of the cross beam 12b correspond to a group of installation points, and a group of installation points includes a total of four horse stools 1 6 and horse stools 2 11, and each horse stool 1 6 or horse stool 2 11 corresponds to a installation point of the cross beam 12b.

[0042] According to the structural characteristics of the roof hanger 12 and the building structure on site, the shear wall 1 and the structural beam 7 are reasonably matched and distributed so that the horse stool 1 6 and the horse stool 2 11 form a group of four, corresponding to the installation of one roof hanger 12. The reasonable layout of the shear wall 1 and the installation of the structural beam 7 can not only realize the balanced bearing of the entire building on multiple roof hangers 12, but also reasonably plan the layout and quantity of the roof hangers 12.

[0043] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
