Description
Technical field
The present invention relates to a kind of large-scale arcuate structure template method and the vertical centering device thereof of controlling is installed, is the control of the arc formwork size while being exclusively used in cooling tower construction.
Background technology
The control of the arc formwork size when to cooling tower construction is generally by total powerstation, total powerstation, i.e. electronic total station.Being a kind of light, mechanical, electrical high-tech measuring apparatus that integrates, is to catchment the straight angle, vertical angle, distance (oblique distance, flat distance), vertical survey function in the instrument of surveying and mapping system of one.Because of it, once settle instrument and just can complete whole surveying works on this survey station, so be referred to as total powerstation.Be widely used in precise engineering survey or the deformation monitoring fields such as heavy construction on the ground and construction of underground tunnel, but applicable in highly not high by this job practices of total station survey arc formwork size, but the increase along with height, increasing of inner shuttering supporting, can affect the precision of measuring controls, and operating difficulties, loses time, sometimes even cannot operate.The control of the arc formwork size during now to cooling tower construction is by total powerstation, utilizes the hanging scaffold of centre of cooling column suspension as receiving target, from hanging scaffold center, draws steel ruler, carries out the measurement of air duct radius and controls; For controlling the absolute altitude of hanging scaffold, at pond baseboard Shang You center, draw 4 and measure control line, control point is located at distance center 8m place, before each installation form, utilizes transit to control the absolute altitude (distance by the line of hanging scaffold center and transit and the angle of base plate and transit and center is controlled) of hanging scaffold.Existing this measurement control method, when highly higher, can produce and measure inaccurately, and the operating time is long, and the situation that sometimes cannot operate, and to programming, brings very large impact.
Summary of the invention
The object of the invention is to overcome the inaccurate problem that even cannot operate of control of above-mentioned existing arc formwork size during to cooling tower construction, provide a kind of large-scale arcuate structure template that method and the vertical centering device thereof of controlling is installed, vertical centering device and measuring method thereof that the method and device utilization arrange, the exterior sheathing size of barrel can be determined and fixed, reach the object of accurate control template size, even when highly higher, also can measure exactly.
Object of the present invention is achieved through the following technical solutions: large-scale arcuate structure template is installed the method for controlling, and comprises the following steps:
(a) for the exterior sheathing of barrel accurately being located, the central point of cooling tower is determined and made clearly sign, make a vertical centering device, vertical centering device is arranged in cooling tower and the center of vertical centering device follows the central point of cooling tower to overlap, vertical centering device is to control by being the fixing steel cable of criss-cross four direction, when positioning, on the formwork-support of building concrete, fix four leading blocks one, leading block is arranged on sustained height and is evenly distributed in same level, four directed pulleys one and four adjusting devices one are set on the ground, wherein one end of a steel cable is in the point of adjustment of vertical centering device, steel cable becomes vertical direction by leading block by horizontal direction extension and extends, contributing to operating personnel to stand in ground controls, the other end is fixed with ground adjusting device one after being wrapped in leading block one, at four direction, it is adjusted simultaneously, after vertical centering device maintenance level, being about to adjusting device fixes, utilize said method, the position of vertical centering device can be fixed, when operating personnel carry out large-scale arcuate structure template installation, control position reasonably, the final location accurately of realizing.
(b) above the center of vertical centering device, welded a screw rod, the fixing end of invar tape on screw rod, the other end of invar tape and the template of cooling tower are fixed, angle between invar tape and horizontal plane is α, distance between screw rod and template is L1, invar tape is steel ruler one, the scope of angle a is at 0 degree--between 30 degree, width increase along with barrel internal diameter, angle is just less, and this screw rod is mainly used for the fixedly end of invar tape, takes nut to be fixed above, for measuring the distance from hanging scaffold center to inner side template, the numerical value recording is accurate.
(c) after the leveling of vertical centering device, vertical centering adjustment complete, the height of having determined vertical centering device is H, as shown in Figure 3, Figure 4, H=H1+H2, by determining of height H, by the construction diagrams of template, determined the horizontal range L2 of vertical centering device center to inner side template, calculate the distance L 3 from the peak of inner side template to hanging scaffold level point simultaneously, utilized Pythagorean theorem to calculate very thick hanging scaffold center to the distance of inner side template peak
draw, by the invar tape of hanging scaffold overhung, measure, template is accurately located and fixes the most at last, so just can calculate hanging scaffold center to the size of inner formword by the size of vertical centering, thereby determine the size of exterior sheathing, reaches location accurately.
[0006]existing measurement control method, when highly higher, can produce measurement inaccurate, and the operating time is long, and the situation that sometimes cannot operate, to programming, bring very large impact, and take vertical centering device, determine that centre of cooling column is to the size on ground, by template assembly figure, calculate centre of cooling column to the vertical dimension of inner side template, finally by Triangle Principle, calculate the size on the 3rd limit, thereby determined that the cooling tower crane heart is to the size of inner side template top, then the plus-minus silk by outboard template carries out template position adjustment, reached recently the accurate location of template.
