The specific embodiment:
Referring to figs. 1 through Figure 11, this concrete enforcement by the following technical solutions: its operating procedure is as follows:
1, consider the allowance of part and the important anchor point of intersecting mouth when the material blanking, in strict accordance with technological requirement, perform the datum mark of every pipe fitting and the mark of anchor point, it is clear to print mark with steel drift, and indicates the position of steel drift seal with marking pen.All steel pipes are all established an anchor point datum level, and other each point is that benchmark is made with this datum level all.Stamp " JZ " mark at this some place with steel seal, as Fig. 1;
2, be cut with the place (the bending point that refers to the bearing diagonal that passes through mutually with steel pipe column) of intersecting mouth at steel pipe, mark the highs and lows of intersecting mouth and the stringcourse of both sides, as Fig. 2;
3, on the steel pipe top be the place of angular cut, mark the highs and lows of otch and stringcourse and the gyration of both sides, when marking out the angle of the stringcourse of the highs and lows of otch and both sides and rotation simultaneously at the relative position of steel pipe opposite side, as Fig. 3;
When 4, the steel pipe two ends are straight cut, mark 4 Along ents (4 separated time) at two ends, when this body has the anglec of rotation, go out position of rotation at connection end plate subscript.
5, the bolt hole above the flange is holed.Carry out mechanical drawing earlier according to standard component, indicate the required precision of hole and machined surface, process according to drawing and technology main points book then.Before machining, should mark 4 Along ents and charge and attack in its surface with the ocean as the flange face of end plate, as the telltale mark point.After machinery is finished with marking pen to the flange marker number, as Fig. 4;
6, in order to ensure the fitted position precision of member, with H section steel manufacture assembling moulding bed base, carry out levelling with level meter earlier, integral level degree deviation allows for 1mm, amplifies sample at H shaped steel after the levelling, and the ground line-transect is the assembly center line.All locate with the cylindrical of steel pipe the location of all steel pipes on moulding bed, as Fig. 5;
7, will be arranged on the H shaped steel datum level, as locating support by scribing position as the pipe holder of moulding bed.Mark orthogonal two datum lines at mounting plate, stamp foreign dotting punch, as the benchmark bus.Assembling and positioning frame point is welded on the mounting plate, the flange on tubing string flange in the bottom or the straight tube and tubing string are assembled at moulding bed, after assembling was finished, passed examination spot welding was fixed, and base plate or flange are connected with alignment pin with the assembling and positioning frame, as Fig. 6;
8, assemble straight-tube portion at moulding bed, the flange between the straight tube is located and is connected the enterprising luggage of platform with bolt with alignment pin join, as Fig. 7;
9, carry out the assembling of bending tube at moulding bed.Amplifying sample at moulding bed, is benchmark with the anchor point at two ends on the steel pipe column, and the bend pipe position is installed, and checks the angle of bend pipe with ground sample and model.The butt joint inside of tearing bend pipe open the pipe of taking to add the cushions carries out, if spacer tube is equipped with difficulty, can divide several sections fitted lining backing plates, can take cutting or polishing to remove when plate thickness direction and outer tube wall are collided, and guarantees the applying of liner plate and inwall, as Fig. 8;
10, straight tube assembling adjustment finishes, and assembles oblique supporting leg, determines the rigging position of oblique supporting leg with the anchor point on the oblique supporting leg and the anchor point on the straight tube, with position and the angle of ground sample and the oblique supporting leg of anchor point inspection, as Fig. 9;
11, the group of brace is upright, adopts the assembling of alignment pin location, guarantees pitch-row, prevents the connecting plate distortion, as Figure 10;
12, because pipe support installation at the scene all be Bolt Connection, for guaranteeing field erected accuracy, assembling each as requested independently behind the integrated member, carry out integral body assembly unit in advance in factory, whether the inspection member can be installed smoothly.Pre-assembly unit is taked horizontally to carry out assembly unit by big end piecemeal to small end.Bottom segmentation installing conduit saddle plate, dress is welded on the support and with theodolite and smooths, as Figure 11.
This concrete enforcement is the dimensional accuracy control method of tubular construction when blanking, making, assembling, welding of research and experiment three dimensions shape, adopt three dimensions pipe pipe connected structure, being connected of tubing string base plate and built-in fitting, post column sectional connect and are flange bolt and connect, connection between the pipe support also adopts the pipe diagonal brace to add the connecting plate Bolt Connection, require punching rate will reach more than 99%, realization site operation zero is got angry.With stage of assembling and positioning skill upgrading of three-D space structure.
This concrete enforcement has the rapidity of construction and the accurate location of locus, it is the comprehensive utilization of ground sample method and computer setting-out, template, be easy in practice grasp, operate, can accurately carry out the angle of tubulose, the control of dimensional accuracy, farthest guarantee to design desired size, occupied ground is few when making construction simultaneously, and being convenient to member can cut the waste, and is beneficial to and increases work efficiency and reduce cost.
