Background technology:

At present, solder ball rack, net shell are more and more extensive in the application of building field, and its form of structure also becomes more diverse.Pyrometric cone is basic division unit more common in the network engineering, now a lot of job practicess all are in the situation that the lower edge moulding is sling simultaneously and utilized the mouth of pipe to come centering to install aloft with will wind up ball, web member of lifting machine, manually, material, machinery consume larger, and it is coarse that this assembling method all shows slightly, meticulous not, lack construction technology ripe, reliable, science, can't promote at construction field, cause workmanship on the low side, even stay potential safety hazard.

Summary of the invention:

Purpose of the present invention just is to provide a kind of honeycomb type net shell pyrometric cone unit splicing method, and the method can be fast, accurate assembly unit pyrometric cone unit.

As above design, technical scheme of the present invention is: a kind of honeycomb type net shell pyrometric cone unit splicing method, it is characterized in that: six length of side data of pyrometric cone are obtained, emit any two triangles at platform, can with four bolted node spheres of pyrometric cone and five rod member location, take common edge as axle, rotate one of them triangle, align with the distance between two bolted node spheres of remaining this bar of rod member centering and with the mouth of pipe, namely finish the pyrometric cone group to work.

Above-mentioned honeycomb type net shell pyrometric cone unit splicing method, it is characterized in that: concrete steps are as follows:

1) prefabricated firm, smooth steel platform; According to the difference of radius of a ball size in the pyrometric cone, the bulb holder of prefabricated differing heights;

The distance of each ball node that 2) draws according to programming software is emitted the lower lower edge triangle that is comprised of 1 lower edge ball, 2 shared lower edge balls, 2 lower chords and shared lower chord and the 1:1 full pattern of arbitrary triangular of being comprised of the ball that winds up, above-mentioned 2 shared lower edge balls, 2 web members and an above-mentioned shared lower chord at the steel platform; Then the bulb holder with correspondence is placed on respectively four ball node centers, with absolute altitude and fixing on the level gauge centering conduit saddle; Place solder sphere, and rod member corresponding to splicing ball, centering, and spot welding connects;

3) with two web members and an above-mentioned shared lower chord and ball spot welding, all the other two lower chords not with shared ball spot welding;

4) sling with the Simple gantry crane that arranges on the platform triangle that ball, 2 web members, above-mentioned 2 shared lower edge balls and an above-mentioned shared lower chord form that will wind up, share the lower edge ball around bulb holder rotation;

5) come two leg-of-mutton relative positions of centering with last root web member, mouth of pipe centering, spot welding, the pyrometric cone assembling is complete.

The present invention can make the splicing accuracy of pyrometric cone greatly improve, and whole installation process is to carry out at platform, constructs more convenient.

The specific embodiment:

A kind of honeycomb type net shell pyrometric cone unit splicing method, concrete steps are as follows:

1, prefabricated firm, smooth steel platform (1); According to the difference of radius of a ball size in the pyrometric cone, the bulb holder (2) of prefabricated differing heights, the purpose of doing like this is in order to allow the centre of sphere be in sustained height, namely Atria is o'clock on a horizontal plane.

The distance of each ball node that 2, draws according to programming software in the actual unwrapping wire, considers that weld seam shrinks, and adds 3mm as the unwrapping wire size on the basis of this length at the scene.Emit lower edge triangle (by lower edge ball A(3), lower edge ball B(4 at the steel platform), lower edge ball C(5) and lower chord X1(9), X2(10), X3(11)) and arbitrary triangular (by the ball O(6 that winds up) lower edge ball X1(3), lower edge ball X2(4), web member F1(7) web member F2(8) and share lower chord X1(9) form) the 1:1 full pattern.The bulb holder of correspondence is placed on respectively four ball node centers, with absolute altitude and fixing (such as Fig. 1) on the level gauge centering conduit saddle.Place solder sphere, and rod member corresponding to splicing ball, centering, and spot welding connects (such as Fig. 2).

3, two web member F1(7), F2(8) and lower edge joint use pole X1 (9) and ball spot welding, all the other two lower chord X2 (10), X3 (11) not with shared ball spot welding (such as Fig. 3).

4, with the Simple gantry crane that arranges on the platform ball O(6 that will wind up) with web member F1(7), web member F2(8) and share lower edge ball A(3), lower edge ball B(4), lower chord X1(9) triangle that forms slings, and shares the lower edge ball around bulb holder rotation (such as Fig. 4).

5, with last root web member F3(12) come two leg-of-mutton relative positions of centering, mouth of pipe centering, spot welding, pyrometric cone assembling complete (such as Fig. 5).
