Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an extra-long tower crane attachment device suitable for a steel pipe column. Background Art
[0002] In modern high-rise buildings, especially super high-rise buildings, there are many construction problems. Modern buildings are characterized by novel shapes and diversified structures. It is common to use steel structure outer frames to support complex facade designs. This design often faces the problem of how to effectively arrange and attach external tower cranes. In these buildings, due to the complexity of the facade design, in order to facilitate construction, it is often necessary to attach tower cranes at different locations. These attachment points may be far from the ground, resulting in "extra-long attachment" situations. At the same time, the steel outer frame of the building usually uses steel tube concrete columns, which increases the difficulty of fixing the tower crane's attachment parts to these columns.
[0003] The commonly used method at present is to weld the connecting parts of the tower crane directly to the steel pipe column. However, since the commonly used connecting parts on the market are in the shape of straight plates, and the steel pipe column is round, these connecting parts need to be gas-cut into arc shapes at high altitude to adapt to the steel pipe column. Such high-altitude welding is difficult and it is difficult to ensure the welding quality. Moreover, this simple welding method is difficult to adapt to the connection of ultra-long attachment rods and the transmission requirements of bearing force. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

After the steel pipe column is installed, the second connection component of the corresponding height is installed as needed, so as to flexibly adjust the height of the tower crane support unit, thereby improving the use efficiency and flexibility of the steel pipe column. At the same time, the welding operation can be completed on the ground, which significantly reduces the difficulty and complexity of construction and reduces potential safety hazards.

[0019] Thirdly, the utility model sets a horizontal reinforcement plate between the vertical connection plates, which enhances the stability and load-bearing capacity of the entire attachment device. A first reinforcement rib and a second reinforcement rib are set between the ear plates, wherein the second reinforcement rib is in the shape of a right triangle, and its right angle side is fixedly connected to the ear plate and the plate seat. This structure optimizes the force distribution, reduces the risk of deformation due to long-term use or abnormal load, and further improves the stability and safety of the tower crane in long-term use, and is particularly suitable for heavy-load material handling in high-rise building construction.

The second reinforcing rib of this structure not only ensures the overall strength of the second connecting component, but also ensures the stability of the connection between the first component and the second component. At the same time, this structure is also easy to install and disassemble, which improves the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1-Figure 4 As shown, the present application provides an extra-long attachment device for a tower crane suitable for a steel pipe column, comprising a first connection assembly and a second connection assembly. The first connection assembly comprises a base plate 10, one side of the base plate 10 is fixedly connected to the second connection assembly, and the other side is fixedly provided with a plurality of vertical connection plates 11 for connecting the steel pipe column 100. These vertical connection plates 11 are welded to the steel pipe column 100 in a direction parallel to the axis of the steel pipe column 100, and a horizontal reinforcement plate 12 is fixedly provided between two adjacent vertical connection plates 11 to enhance the overall stability.
[0037] In a specific embodiment, the bottom plate 10 and the vertical connecting plates 11 are both square steel plates, and the width of the bottom plate 10 is generally not less than the diameter of the steel pipe column 100. Among them, the plurality of vertical connecting plates 11 include two short connecting plates 111 and two long connecting plates 112, which are vertically welded to one side of the bottom plate 10, and the two long connecting plates 112 are arranged on the inner side of the two short connecting plates 111 and symmetrically distributed along the axis direction of the steel pipe column 100. The plurality of vertical connecting plates 11 can also be opened at a certain angle (not shown in the figure) in the direction away from the central axis to provide better bearing capacity.
[0038] In a specific embodiment, the contact portion (ie, the welding portion) between the vertical connecting plate 11 and the steel pipe column 100 is parallel to the axial direction of the steel pipe column 100, so that the force borne by the weld is more uniform and better able to withstand vertical loads and lateral forces.
[0039] like Figure 1 and Figure 3 As shown, the end of the short connecting plate 111 is provided with an arc surface fitting the outer surface of the steel pipe column 100 on one side close to the axis of the steel pipe column 100, and a welding groove of 30° to 45° is provided on the other side, and the end of the long connecting plate 112 is provided with an arc surface fitting the outer surface of the steel pipe column 100.
[0040] In a specific embodiment, according to the diameter of the steel pipe column 100 to be installed, the ends of the long connecting plate 112 and the short connecting plate 111 are cut into arc surfaces that fit the steel pipe column 100, and a 45° welding groove is cut on the other side of the arc surface of the end of the short connecting plate 111. During installation, the arc surfaces of the long connecting plate 112 and the short connecting plate 111 are abutted against the outer surface of the steel pipe column 100, and welded on both sides of the contact part. Due to the provision of the groove, the welding material can be more easily filled into the end of the short connecting plate 111 during welding, thereby improving the strength and crack resistance of the joint and achieving better welding.

A first horizontal reinforcing plate 121 is arranged between the two short connecting plates 111, and a second horizontal reinforcing plate 122 is arranged between the short connecting plate 111 and the long connecting plate 112. The first horizontal reinforcing plate 121 and the second horizontal reinforcing plate 122 are welded to the adjacent vertical connecting plates 11 and the bottom plate 10, respectively.

By arranging the horizontal reinforcing plates 12, the rigidity and stability between the vertical connecting plates 11 are increased, the load is dispersed and additional support is provided, so that the first connecting assembly remains stable when subjected to vertical or horizontal loads.
[0043] like Figure 5-Figure 7 As shown, the second connection assembly includes a plate base 20, and two ear plates 21 parallel to each other and perpendicular to the plate base 20.

[0044] In a specific embodiment, each ear plate 21 is provided with two through holes, and the through holes on the two ear plates 21 form two pairs of pin holes 22, and each pair of pin holes 22 is fixed with a pin (not shown in the figure). The two pins are respectively connected to the two support units provided on the tower crane support to form two force components, thereby meeting the requirements of connecting and attaching force transmission of the super-long attachment rod. Among them, at least one first reinforcement rib 23 is provided between the two pairs of pin holes 22,
[0045] like Figure 5-Figure 7 As shown, a second reinforcement rib 24 is arranged between the plate seat 20 and the side of the ear plate 21 away from the first reinforcement rib 23 .
[0046] like Figure 1 and Figure 8 As shown, the plate seat 20 is provided with a plurality of bolt holes 201 for fixing the base plate 10 , and the bolt holes 201 are evenly distributed on both sides of the second reinforcing rib 24 . The fasteners 25 are high-strength bolts, and steel gaskets 26 are further provided between the high-strength bolts and the base plate 10 and the plate seat 20 .
[0047] In a specific embodiment, three second reinforcing ribs 24 are arranged between each ear plate 21 and the plate seat 20, and the second reinforcing ribs 24 are in the shape of a right triangle, and two right-angled sides thereof are respectively welded to the ear plate 21 and the plate seat 20. The plate seat 20 is further provided with two rows of bolt holes 201, each row having six bolt holes 201, which are distributed on both sides of the three second reinforcing ribs 24. Figure 4 As shown, threaded holes corresponding to the plate seat 20 are arranged on the bottom plate 10 , and the threaded holes on the bottom plate 10 are arranged between the four vertical connecting plates 11 .
[0048] In a specific embodiment, before the steel pipe column 100 is installed, the first connection assembly is first welded to the outer surface of the steel pipe column 100, and then the horizontal reinforcement plate 12 is welded between two adjacent vertical connection plates 11. After the first connection assembly is installed, the steel pipe column 100 is installed to a preset position around the tower crane support, and then the second connection assembly is fixedly installed at the position of the first connection assembly at a corresponding height by high-strength bolts according to actual needs. The second connection assembly is respectively connected to the two support units on the tower crane support to form a two-force component. This structure improves the efficiency and flexibility of the use of the steel pipe column 100. At the same time, the welding operation can be completed on the ground, which significantly reduces the difficulty and complexity of construction and reduces potential safety hazards. The first connection assembly and the second connection assembly are fixed by high-strength bolts, which are stable and easy to install and disassemble, thereby improving the overall construction efficiency.
