Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Present embodiment discloses a kind of locating rack for the construction of contrary sequence method pre-buried lattice column, as Figure 1-3, including square frame body, frame body is that double-decker includes upper strata support body 1 and lower floor's support body 2, upper strata support body 1 and lower floor's support body 2 are connected by column, four end angles of lower floor's support body 2 are fixed with footing 15, and the center of upper strata support body 1 and lower floor's support body 2 is provided with the frame mouth 3 for transferring for lattice column, and frame mouth 3 is enclosed square structure by four grid beams 4；Also include guide cylinder 6, guide cylinder 6 be available for lattice column penetrate and along guide cylinder 6 inwall slide, guide cylinder 6 at the center of frame mouth 3 and and grid beam 4 between leave gap 12, the grid beam 4 of lower floor's support body 2 is respectively connected with bolt 5 for pushing against guide cylinder 6；
Concrete, as shown in Figure 4, guide cylinder 6 cross section is square, and including the angle steel 10 being positioned at its four end angles, the jaws of angle steel 10 inwardly, is welded with fixed plate 11 between adjacent angle steel 10, bolt 5 is relative with fixed plate 11.The upper end four edges of guide cylinder 6 is equipped with flange 9, and the outer side edges of flange 9 is along being fixedly connected with registration roller 7, and registration roller 7 is cylindric, and its centerline is welded with flange 9, it is possible to use securing member to connect；The end face of upper strata support body 1 be provided with for placement positioning roller 7 and with the arcuate groove 8 of registration roller 7 adaptation, the length of arcuate groove 8 is more than the length of registration roller 7.
It addition, the grid beam 4 of upper strata support body 1 is also provided with the bolt 5 for pushing against guide cylinder 6.Lower floor's support body 2 is provided with the ladder 13 being connected to upper strata support body 1, and the edge of upper strata support body 1 is provided with railing 14.
When lattice column transfers construction, locating rack is installed in advance in stake holes, locating rack rest on the ground easily controllable installation accuracy, lattice column starts to transfer after being lifted by crane by crane at frame mouth 3, by guide cylinder 6 as guiding, guide cylinder 6 upper end is positioned with arcuate groove 8 by registration roller 7, and lower end is pushed against by the bolt 5 at lower floor's support body 2 grid beam 4 so that guide cylinder 6 keeps plumbness.Lattice column is transferred to guide cylinder 6 along guide cylinder 6 slip so that lattice column transfer the impact being susceptible to external factors, it is easier to control its perpendicularity.
And in lattice column decentralization process, detect when lattice column dip deviation exceedes predetermined value, can be finely adjusted by the bolt 5 at lower floor's support body 2 grid beam 4.
Concrete, when needs are finely adjusted, owing to leaving gap 12 between guide cylinder 6 and grid beam 4, by the bolt 5 at compensating roller lower floor support body 2 grid beam 4, so that guide cylinder 6 swings, during such as guide cylinder 6 side oscillation wherein, another registration roller 7 relative with this side is placed in arcuate groove 8 as oscillation center, and owing to the length of arcuate groove 8 is greater than the length of registration roller 7, guide cylinder 6 is in swing process, other registration roller 7 outside removing as the registration roller 7 of oscillation center can also upwards be dug, do not have and the phenomenon of arcuate groove 8 two ends inwall dieback.Owing to lattice column is positioned at guide cylinder 6, by swinging guide cylinder 6, the gradient of lattice column is adjusted, is more beneficial for the control of perpendicularity of lattice column.
It addition, also be provided with bolt 5 at the grid beam 4 of upper strata support body 1 for pushing against guide cylinder 6, at this, bolt 5 pushes against in guide cylinder 6 during lattice column is transferred, and improves the fixation of guide cylinder 6；Perpendicularity of lattice column trim process is unclamped so that guide cylinder 6 is swingable.
In sum, this utility model provides a kind of locating rack for the construction of contrary sequence method pre-buried lattice column, it is possible to position lattice column in lattice column decentralization process so that be easier to control the perpendicularity of lattice column during construction.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, all within design concept of the present utility model, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
