As shown in Fig. 1, Fig. 3 and Fig. 4, plumb aligner bearing 11 is set up in the top of the hole to be provided 17 of the second floor 16.Second floor 16 is positioned at above the first floor 14, and the hole to be provided 17 of the second floor 16 is positioned at directly over positioning control target 10.Plumb aligner bearing 11 offers the light hole 31 supplying the laser beam of plumb aligner 12 to pass, and light hole 31 is positioned at directly over the reference mark mark 15 of the positioning control target 10 of positioning control target 10.What plumb aligner bearing 11 was in the present embodiment makes triangular arrangement by sheet material.The upper surface of plumb aligner bearing 11 is provided with plumb aligner contraposition mark 30, and plumb aligner contraposition mark 30 is identical with the shape of the base of plumb aligner 12.Plumb aligner contraposition mark 30 can be the circle shown in Fig. 3, also can be the rectangle shown in Fig. 4.
Plumb aligner 12 is set up in the upper surface of plumb aligner bearing 11, and by plumb aligner 12 and plumb aligner contraposition mark 30 alignment.Be provided with bottom plumb aligner 12 to throw downwards and survey laser instrument, plumb aligner top is provided with surveys laser instrument to upslide.Downward throwing bottom plumb aligner 12 is surveyed laser instrument and is positioned at directly over the positioning control target 10 of positioning control target 10.
Laser pick-off target 13 is arranged at directly over plumb aligner 12, for receiving the light beam surveying laser instrument to upslide of plumb aligner 12.In the present embodiment, be provided with between laser pick-off target 13 and plumb aligner 12 at least in one deck every floor 18, all offer hole to be provided 19 every floor 18 in each layer, hole to be provided 19 makes to form intervisibility between laser pick-off target 13 and plumb aligner 12.
Plumb aligner 12 of the present invention is erected at the second floor 16 surface, such plumb aligner 12 is the distance between two-layer floor to the distance of positioning control target 10, the sight line length of the bottom of plumb aligner 12 can be increased like this, thus increase the precision of plumb aligner 12, reduce the error to upslide observing and controlling point.
Floor axial line control point Vertical method of the present invention is introduced below in conjunction with accompanying drawing:
Refer to Fig. 1, floor axial line control point Vertical method of the present invention comprises the following steps:
1) at the pre-buried positioning control target 10 in the surface of the first floor 14, the surface of positioning control target 10 is provided with reference mark mark 15.
2) above the hole to be provided 17 of the second floor 16, set up plumb aligner bearing 11, in erection process, the light hole 31 of plumb aligner bearing 11 is adjusted to directly over reference mark mark 15.Use the position of vertical adjustment plumb aligner bearing 11 in the present embodiment.Adjust the surface that plumb aligner bearing 11 is fixed on the second floor 16 by rear use iron nail.
Plumb aligner bearing 11 is provided with plumb aligner contraposition mark 30, plumb aligner contraposition mark 30 the erection speed can accelerating plumb aligner 12 is set, especially as shown in Figure 1, the second floor 16 surface is provided with multiple needs and sets up the measurement point of plumb aligner 12.When plumb aligner 12 has enough to meet the need between multiple measurement point, plumb aligner contraposition mark 30 significantly can accelerate the erection speed of plumb aligner 12.
3) plumb aligner 12 is inserted into the upper surface of plumb aligner bearing 11, in erection process, plumb aligner 12 is aimed at the plumb aligner contraposition mark 30 of plumb aligner bearing 11, and regulate plumb aligner 12.Laser instrument is surveyed in the downward throwing of first opening plumb aligner 12 in the process of adjustment plumb aligner 12; The light hole 31 that the downward light throwing survey laser instrument passes plumb aligner bearing 11 exposes to positioning control target 10.Regulate the verticality of plumb aligner 12 subsequently, make to throw the reference mark mark 15 that the light surveying laser instrument aims at positioning control target 10 surface downwards.
Plumb aligner contraposition mark 30 on plumb aligner bearing 11 can guarantee that the downward throwing of plumb aligner 12 is surveyed laser instrument and is positioned at directly over reference mark mark 15.In the process of the verticality of adjustment plumb aligner 12, throw downwards the light that when reference mark that the light surveying laser instrument aims at positioning control target 10 surface identifies 15, plumb aligner 12 sends and be in plumbness.This regulative mode has governing speed faster.Plumb aligner 12 of the present invention is erected at the second floor 16 surface, and plumb aligner 12 is the distance between two-layer floor to the distance of positioning control target 10, and this can increase the sight line length of the bottom of plumb aligner 12, thus improves the throwing survey precision of plumb aligner 12.
4) laser pick-off target 13 is inserted into above plumb aligner 12 and waits to throw the floor 19 surveyed, wait that throwing the floor surveyed offers preformed hole 20;
5) use plumb aligner 12 to throw to laser pick-off target 13 and survey reference mark.As shown in Figure 2, that in the process of throwing survey reference mark, first opens plumb aligner 12 top surveys laser instrument to upslide, the lower surface of the light beam irradiation that sends of laser instrument to laser pick-off target 13 is surveyed, in the point of irradiation position of the lower surface writing light beam of laser pick-off target 13 as the first throwing measuring point A to upslide.Subsequently by plumb aligner 12 first direction 90-degree rotation in the horizontal direction, throw measuring point B in the point of irradiation position of the lower surface writing light beam of laser pick-off target 13 as second.Subsequently by plumb aligner 12 first direction continuation 90-degree rotation in the horizontal direction, throw measuring point C in the point of irradiation position of the lower surface writing light beam of laser pick-off target 13 as the 3rd.Subsequently by plumb aligner 12 first direction 90-degree rotation in the horizontal direction, throw measuring point D in the point of irradiation position of the lower surface writing light beam of laser pick-off target 13 as the 4th.Throwing first after first to fourth throwing measuring point record completes between measuring point A and the 3rd throwing measuring point C uses straight line AC to connect, and throws between measuring point B and the 4th throwing measuring point D use straight line BD to connect by second; Using the intersection point F of above-mentioned two straight lines AC, BD as waiting the reference mark of throwing the axis surveying floor.
Plumb aligner 12 of the present invention is erected at the second floor 16 surface, such plumb aligner 12 is the distance between two-layer floor to the distance of positioning control target 10, the sight line length of the bottom of plumb aligner 12 can be increased like this, thus increase the precision of plumb aligner 12, reduce the error to upslide observing and controlling point.Adopt the error that novel described point method can reduce to upslide observing and controlling point further on the ground of laser pick-off target 13 in the process to upslide observing and controlling point.
The above is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, not departing from the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
