Specific embodiment
A kind of handstand triangle steel pipe passes through space truss mutually, comprise concrete bearing 2, end face in concrete bearing 2 is provided with pre-embedded steel slab 7, below pre-embedded steel slab 7, be welded with the shearing resistance steel pipe 4 that is embedded in the concrete bearing 2, be fixedly welded with cross ribs grillage 8 at hollow ball base-plate 3, the end face of cross ribs grillage 8 is circular arc, bolt 6 and nut 1 are fixed together pre-embedded steel slab 7 and hollow ball base-plate 3, circular arc end face at cross ribs grillage 8 is welded with hollow ball 9, sphere at hollow ball 9 is provided with a pair of hollow ball node hole 10, two hollow ball node holes 10 are take the centre of sphere point by hollow ball 9 and the straight line vertical with pre-embedded steel slab 7 as axis of symmetry, in hollow ball node hole 10, be fixedly welded with the steel pipe 5 that forms the handstand triangle edges, between the summit of the steel pipe 5 that forms the handstand triangle edges, be welded with junction steel plate.
Between hollow ball base-plate 3 and pre-embedded steel slab 7, be provided with cross-over block.
A kind of triangle steel pipe that stands upside down passes through the assemble method of space truss mutually, may further comprise the steps:
The first step, processing and fabricating adopt intersection pipe cutting machine cutting processing to form the steel pipe 5 of handstand triangle edges with the hollow ball 9 in two hollow ball node holes 10;
Second step, on space truss is made platform, hollow ball 9 and the steel pipe 5 that forms the handstand triangle edges are eliminated rust, and the brushing anticorrosive paint;
The 3rd step, the end face of cross ribs grillage 8 is processed into circular arc, makes the radian of end face circular arc of cross ribs grillage 8 identical with the radian of the cylindrical of hollow ball 9, with cross ribs grillage 8 be welded on hollow ball base-plate 3 above;

For guaranteeing carrying out smoothly of assembly unit process, guaranteeing to select rational baiting method not only can increase work efficiency for different members under the prerequisite that the welding junction assembling process requires, also can save cost.This engineering requires to select respectively intersection-line cutting machine with pipe cutter different members to be carried out blanking for the assembly unit that steel pipe passes through trussed construction mutually.
For truss web, in order to obtain its intersection interface, adopt intersection-line cutting machine to carry out blanking.Its concrete operation step is:
(1) under the prerequisite of considering in advance main couple arch camber amount, adopt AUTOCAD software to set up the three-dimensional wireframe model of trussed construction, require modeling necessary 100% accurate;
(2) wire-frame model is converted to DXF format standard figure convert file, and is entered in the WIN3D design software and calculates, generate the cutting data list;
(3) after PIPE-COAST accepts the cutting data list, generate the processing instruction of single pipe fitting, and then carry out rational jacking according to material specification, at last procedure is dealt into the workshop, implement cutting in batches; In order to make provision against emergencies, if when the quantity of every batch of cutting is larger, can cut first one, carry out the appearance and size inspection, confirm to carry out again large batch of cutting after errorless;
(4) comparing with intersection cutting stock method, adopt the pipe cutter blanking not only easy to operate, and can save a large amount of costs of transportation and processing cost, therefore, is the upper lower edge supervisor of straight mouth for interface, need not adopt the pipe cutter blanking.
