Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of handstand triangle steel pipe passes through space truss mutually, comprise concrete bearing 2, on the end face of concrete bearing 2, be provided with pre-embedded steel slab 7, below pre-embedded steel slab 7, be welded with the shearing resistance steel pipe 4 being embedded in concrete bearing 2, on hollow ball base-plate 3, be fixedly welded with cross ribs grillage 8, 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, on the circular arc end face of cross ribs grillage 8, be welded with hollow ball 9, on the sphere of hollow ball 9, be provided with a pair of hollow ball node hole 10, two hollow ball node holes 10 are to take that centre of sphere point by hollow ball 9 straight line vertical with pre-embedded steel slab 7 be axis of symmetry, in hollow ball node hole 10, be fixedly welded with the steel pipe 5 that forms handstand triangle edges, between the summit of steel pipe 5 that forms 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.
The triangle steel pipe that stands upside down passes through an assemble method for space truss mutually, comprises the following steps:
The first step, processing and fabricating, with the hollow ball 9 in two hollow ball node holes 10, adopt intersection pipe cutting machine cutting processing to form the steel pipe 5 of handstand triangle edges;
Second step, on space truss is made platform, hollow ball 9 and the steel pipe 5 that forms handstand triangle edges are eliminated rust, and 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, by cross ribs grillage 8 be welded on hollow ball base-plate 3 above;

For guaranteeing carrying out smoothly of assembled process, guaranteeing, under the prerequisite that welding junction assembling process requires, to select rational baiting method not only can increase work efficiency for different members, also can save cost.The assembled requirement that this engineering is passed through trussed construction mutually for steel pipe selects respectively intersection-line cutting machine and pipe cutter to carry out blanking to different members.
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) considering in advance under the prerequisite of main couple arch camber amount, adopting AUTOCAD software to set up the three-dimensional wireframe model of trussed construction, requiring modeling must 100% accurate;
(2) wire-frame model is converted to DXF format standard figure convert file, and is entered in WIN3D design software and calculates, generate cutting data list;
(3) PIPE-COAST accepts after cutting data list, generates the processing instruction of single pipe fitting, and then carries out rational jacking according to material specification, finally procedure is dealt into workshop, implements cutting in batches; In order to make provision against emergencies, if when the quantity of every batch of cutting is larger, can first cut one, carry out appearance and size inspection, confirm after errorless to carry out again large batch of cutting;
(4) comparing with intersection cutting stock method, adopt 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 mouthful for interface, need not adopt pipe cutter blanking.
