Referring to fig. 1-3, a tower crane foundation conversion joint is shown, which includes a conversion base 1 and a conversion end 2 for connecting a tower crane foundation, where the conversion base 1 includes four conversion beams 11 surrounding a square along the circumferential direction, and the four conversion beams 11 are detachably connected; a plurality of first hole groups 113 used for being connected with the tower crane 3 are arranged on the upper end surface of the conversion beam 11 along the axial direction; the lower end surface of the conversion beam 11 is provided with a plurality of second hole groups 115 which are arranged along the axial direction and used for being connected with the conversion end head 2; the conversion end head 2 comprises a face plate 21 used for connecting a second hole group 115, a bottom plate 23 used for connecting a tower crane foundation and a rib plate 22 arranged between the face plate 21 and the bottom plate 23.
Specifically, the tower crane 3 is fixed above the conversion base 1, 4 conversion end heads 2 are connected below the conversion base 1, and the conversion end heads 2 are connected with a tower crane foundation; the conversion seat 1 comprises four conversion beams 11 which surround a square along the circumferential direction, and the four conversion beams 11 are detachably connected; therefore, the four conversion beams 11 can adjust the assembly structure according to the positions of the four embedded fasteners on the tower crane foundation, referring to fig. 4, A, B, C, D in fig. 4 are respectively drawing setting positions of the four embedded fasteners of the tower crane foundation, A, B, C, E are respectively actual setting positions of the four embedded fasteners of the tower crane foundation, that is, the position of E is deviated from the position of D, so that the four conversion beams 11 form a conversion base 1 which is erected above A, B, C, E; in addition, the upper end face of the conversion beam 11 is provided with a plurality of first hole groups 113 arranged along the axial direction for connecting with the tower crane 3, and the first hole groups 113 can be selected from the four conversion beams 11 to be combined with the tower crane 3, and as a matter of course, the four first hole groups 113 form a square. Because the conversion base 1 can not be directly connected with the embedded fixing piece of the tower crane foundation, the conversion end head 2 is connected by the second hole group 115 on the lower end surface of the conversion beam 11, and then the conversion end head 2 is connected with the embedded fixing piece.
So, even there is the deviation in tower crane foundation's pre-buried mounting position, also can make tower crane foundation and tower crane 3 connect, and need not tear tower crane 3 that has the deviation and make new tower crane foundation again, reduce construction cost by a wide margin.
In some specific embodiments, referring to fig. 1 and 2, the cross section of the transfer beam 11 is i-shaped, and the upper flange 111 and the lower flange 112 of the transfer beam 11 are provided with mounting holes 114 arranged along the axial direction; the adjacent transfer beams 11 are fixed through connecting pieces 12, and the connecting pieces 12 and the mounting holes 114 are fixed through bolts. It should be noted that, the upper flange 111 includes two upper flanges on two sides, and the lower flange 112 includes two lower flanges on two sides, that is, two rows of mounting holes 114 are respectively formed on the upper end surface and the lower end surface of the transfer beam 11; in order to mount more stably, the connecting piece 12 is T-shaped, and the connecting piece 12 and each conversion beam 11 are fixed by at least two rows of bolts.
In some specific embodiments, referring to fig. 2, in order to make the transition seat 1 better adapted to be connected to the tower crane 3 and the transition head 2, respectively, as much as possible, the first hole set 113 and the second hole set 115 are both composed of a plurality of holes distributed circumferentially. When the conversion beam 11 is covered by four pre-buried fixing pieces, the installation structure of the four conversion beams 11 may be adjusted, which is equivalent to that the conversion beam 11 is overlapped with one of the pre-buried fixing pieces to rotate, and after the conversion beam 11 rotates, the first hole group 113 and the second hole group 115 do not necessarily correspond to the holes of the tower crane 3 and the conversion end head 2; the first hole group 113 and the second hole group 115 are both formed by a plurality of holes distributed circumferentially, and when the conversion beam 11 rotates, the holes distributed circumferentially can also be matched with the holes of the tower crane 3 and the conversion end 2.
Generally, the lower part of the tower crane 3 is fixed by four fixing columns, and each fixing column is fixed by four holes distributed circumferentially, referring to fig. 2, the number of the holes in the first hole group 113 is a multiple of four, and the number of the holes in the second hole group 115 is a multiple of four. So, when first punch combination 113 takes place to rotate, only need wherein four holes and tower crane 3 cooperation can.
In some specific embodiments, referring to fig. 3, the principle of the cooperation between the first hole group 113 and the tower crane 3 is the same, and generally, each pre-buried fixing member of the tower crane foundation is also fixed by four holes distributed circumferentially. Four first fastening holes 211 are provided in the face plate 21 of the conversion head 2, which holes are circumferentially distributed and are intended to be connected to the second set of holes 115; be provided with a plurality of second fixed orifices 231 that are the circumference and distribute and be used for being connected with the tower crane foundation on the bottom plate 23 of conversion end 2, the quantity of second fixed orifices is the multiple of four.
In some embodiments, in order to make the structure of the conversion socket 1 sufficiently strong, the material of the conversion beam 11 is Q235 steel.
In some embodiments, to prevent the transfer beam 11 from being easily bent, reinforcing ribs (not shown) are disposed between the upper flange 111 and the lower flange 112 of the transfer beam 11 in an axial direction. Of course, the reinforcing bars do not block the mounting holes 114, the first hole group 113 and the second hole group 115. The reinforcing bars are fixed between the upper flange 111 and the lower flange 112 by welding.
The distance between the first hole group 113 and the first hole group 113 may be determined according to actual conditions, and the distance between the second hole group 115 and the second hole group 115 may be determined according to actual conditions. The smaller the distance between the tower crane and the tower crane is, the more the conditions of the tower crane 3 and the tower crane foundation can be matched with each other.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
