2) by the combination laser laying out instrument horizontal center side of being placed on window flange, central laser bundle Z and the datum line X11 of the injection of combination laser laying out instrument are contour and be vertically projected in furnace shell inside panel plane, produce a central cross subpoint, this subpoint is exactly the installation centre of location point of the thermal radiation pin support of corresponding the party's window;
3) Steel Ruler is utilized in step 2) the installation centre of location point vertical center line determined identifies upper pin or the leftover bits and pieces endpoint location of pin bearing, and locate absolute altitude angle bar in this means of spot welds temporarily;
4) step 2 is repeated) and step 3) successively combination laser laying out instrument is placed on its other party window, the installation centre of location point of all thermal radiation pin supports can be located, then installation foot bearing on absolute altitude angle bar, is weldingly fixed on thermal radiation pin support on furnace shell inside panel after centering.
A kind of Combined laser pay-off instrument, comprise laser beam emitting head, spirit bubble one, spirit bubble two and square bracket, side's bracket leading flank is provided with scale label between two parties, laser beam emitting head radiating laser beams axle and be parallel to side bracket on plane corresponding with square bracket scale label center, perpendicular to square bracket leading flank, on side's bracket, plane is also provided with spirit bubble one, spirit bubble two, plane width direction on the spirit bubble one length direction side of being parallel to bracket, plane length direction on the spirit bubble two length direction side of being parallel to bracket, square bracket two ends are respectively equipped with magnet.
Described laser beam emitting head is the function head of Laser Line Marker or laser collimator.
Compared with prior art, the invention has the beneficial effects as follows: eliminate and the step that three-dimensional cartesian coordinate system measures and identify is set up to structural mount coordinate central point, can to the directly one-time positioning fast of the coordinate central point of remotely structure member, decrease survey calculation workload, positional accuracy is high, meet construction quality requirement, installation qualification rate reaches 100%, improves operating efficiency three times.
