Detailed description of the invention
Below in conjunction with drawings and Examples, essentiality content of the present utility model is described in further detail:
As shown in Figures 2 to 5: a kind of attachment of the overlength for tower crane rod member, rod member 13 is provided with four, determine according to tower crane 12 and the distance of building 14, every root rod member 13 resolves into more piece, connected by flange between every pole part 13, the length of every pole part 13 is no more than 8 meters, rod member 13 adopts cancelled structure, be formed by connecting by leading role's steel 1 and lacing 2, the two ends connection fixing base respectively of the rod member 13 after having spliced, one end connects on tower crane 12, other end connecting building thing 14 (see Fig. 1).Leading role's steel 1 is provided with four, and in square arrangement, its sectional dimension is L100mm × 10mm, lacing 2 is the steel band of articulating leading role steel 1, and it is of a size of L50mm × 5mm, the lattice of extrapolation size 600mm × 600mm, two lacing 2 spacing are 1000mm, and lacing 2 is 45 degree with the angle of trunk.Flange is for being foursquare steel plate 3, the centre of steel plate 3 is provided with rectangular opening 4, the four edges of steel plate 3 is provided with uniform through hole 5, for reaching the effect firmly connected, every limit of steel plate is provided with five, totally 20 through holes 5, the diameter of through hole 5 is 17mm, and diameter 16mm bolt can be used to be fixedly connected with by two pole parts 13.
Permanent seat is welded by otic placode 6, plectane 7, channel-section steel 8, gusset 9 and base plate 10, otic placode 6 is provided with two pieces, the upper end of otic placode 6 is circular arc, its length is 380mm, width is 210mm, thickness is 20mm, the upper end welding plectane 7 of otic placode 6, lower end welding channel-section steel 8, the length of channel-section steel 8 is that 480mm, width and otic placode 6 is similar.Otic placode 6 and plectane 7 are provided with coaxial axis hole 11, in order to interspersed pivot pin.The external diameter of plectane 7 is 140mm, thick 8mm.The center of the end face welding base plate 10 of channel-section steel 8 one end, base plate 10 is welded respectively by triangle gusset 9 in four sides of channel-section steel 8.The thickness of gusset 9 is 12mm, and base plate 10 is the square of length of side 660mm, thickness is 20mm, and adopt 18# channel-section steel, otic placode 6 and plectane 7 all adopt A3 steel.
Embodiment: as shown in Figure 1: according to the distance of tower crane 12 apart from building 14, design and produce the attachment rod member 13 that overall length matches, the auxiliary implement that attachment rod member 13 is installed is the manual chain hoist of tower crane 12 itself and 2 5t, during installation, first with tower crane 12, rod member 13 lifting is put in place, one to adhere to frame bearing pin pin joint good with tower body, load onto spring cotter, other end jack locks, correct tower lifting, 12 squareness, finally connect the bearing on other end and building 14.Due to attachment rod member 13 overlength, deadweight is comparatively large, is therefore respectively that an insurance steel cable ties up on tower body and building 14 respectively at the two ends of rod member 13.
