Abstract
A method for assembling triangular cone units of a honeycomb type reticulated shell is characterized by comprising the following steps: the six side length data of the triangular cone are solved, any two triangles are released on the platform, four node balls and five rod pieces of the triangular cone can be positioned, one of the triangles is rotated by taking a shared edge as an axis, the distance between the two node balls of the rod is aligned by using the remaining rod piece, and the pipe orifice is aligned, so that the triangular cone pairing work is completed. The invention can assemble the triangular cone unit quickly and accurately.
Description
Technical field:
The invention belongs to a kind of space structures mounting method, particularly a kind of honeycomb type net shell pyrometric cone unit splicing method.
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 network engineering, now a lot of construction method is all sling when lower edge is shaping simultaneously utilize the mouth of pipe to carry out centering installation aloft with will wind up ball, web member of lifting machine, manually, material, machinery consume larger, and this assembling method all shows slightly coarse, meticulous not, lack construction technology that is ripe, reliable, science, cannot promote at construction field, cause workmanship on the low side, even leave potential safety hazard.
Summary of the invention:
Object of the present invention is just to provide a kind of honeycomb type net shell pyrometric cone unit splicing method, and the method can quick, accurate assembled pyrometric cone unit.
As above conceive, technical scheme of the present invention is: a kind of honeycomb type net shell pyrometric cone unit splicing method, it is characterized in that: pyrometric cone six length of side data are obtained, platform is released any two triangles, by pyrometric cone four bolted node spheres and five rod member location, can be axle with common edge, rotate one of them triangle, the mouth of pipe is aligned by the distance between two bolted node spheres of remaining this bar of rod member centering, namely complete pyrometric cone group to work.
Above-mentioned honeycomb type net shell pyrometric cone unit splicing method, 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 pyrometric cone, the bulb holder of prefabricated differing heights;
2) distance of each ball node drawn according to programming software, the lower edge triangle be made up of 1 lower edge ball, 2 shared lower edge balls, 2 lower chords and shared lower chord under steel platform is released and the 1:1 full pattern of arbitrary triangular be made up of the ball that winds up, above-mentioned 2 shared lower edge balls, 2 web members and an above-mentioned shared lower chord; Then the bulb holder of correspondence is placed on four ball node centers respectively, also fixing with absolute altitude on level gauge centering conduit saddle; Place solder sphere, and the rod member that splicing ball is corresponding, centering, and spot welding connects;
3) by 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 triangle of the Simple gantry crane that platform is arranged by the ball that winds up, 2 web members, above-mentioned 2 shared lower edge balls and above-mentioned shared lower chord compositions, share lower edge ball and rotate around bulb holder;
5) carry out centering two leg-of-mutton relative positions, mouth of pipe centering, spot welding with last root web member, pyrometric cone assembling is complete.
The present invention can make the splicing accuracy of pyrometric cone greatly improve, and whole installation process is carried out on platform, constructs more convenient.

Detailed description of the invention:
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 pyrometric cone, the bulb holder (2) of prefabricated differing heights, the object done like this is to allow the centre of sphere be in sustained height, and namely Atria is o'clock on a horizontal plane.
The distance of each ball node 2, drawn according to programming software, at the scene in actual unwrapping wire, considers that weld seam shrinks, the basis of this length adds 3mm as unwrapping wire size.Steel platform is released lower edge triangle (by lower edge ball A(3), lower edge ball B(4), 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 shared lower chord X1(9) form) 1:1 full pattern.The bulb holder of correspondence is placed on four ball node centers respectively, also fixes (as Fig. 1) with absolute altitude on level gauge centering conduit saddle.Place solder sphere, and the rod member that splicing ball is corresponding, centering, and spot welding connects (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 (as Fig. 3).
4, will to wind up ball O(6 with the Simple gantry crane that platform is arranged) with web member F1(7), web member F2(8) and shared lower edge ball A(3), lower edge ball B(4), lower chord X1(9) triangle that forms slings, shares lower edge ball and rotate (as Fig. 4) around bulb holder.
5, with last root web member F3(12) carry out centering two leg-of-mutton relative positions, mouth of pipe centering, spot welding, pyrometric cone assembling complete (as Fig. 5).
