Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 7As shown, the method of installing and controlling large-scale arc-shaped structure templates determines and clearly marks the center point of the cooling tower, and makes a vertical centering device. The vertical centering device is set in the cooling tower and the center of the vertical centering device follows the The center points of the cooling tower coincide, and the vertical centering device is controlled by steel cables fixed in four directions in the shape of a cross. When positioning, four guide pulleys are fixed on the formwork support frame 16 that has been poured. 17. Set four directional pulleys 19 and 4 adjusting devices 18 on the ground, one end of one of the steel ropes is on the adjustment point of the vertical centering device, and the other end is wound around the directional pulley 17 and passes through the directional pulley 1 After the direction of 19 is adjusted, it is fixed with ...

Embodiment 2

[0032] Such as image 3 , Figure 4 , the vertical centering device comprises a suspension pan 1, a connecting mechanism is installed on the top of the suspension pan 1, a pulley mechanism is fixed below the suspension pan 1, the pulley mechanism is connected with a steel wire rope 6 and a steel ruler 8, and the steel wire rope 6 is set on the pulley On the outer wall of the mechanism, one end of the steel wire rope 6 is connected with an adjustment device, and the other end is connected with a hanging hammer 7, and both the adjusting device and the hanging hammer 7 are arranged below the pulley mechanism, and the center line of the hanging hammer 7 and the center line of the hanging pan 1 set on the same straight line. The center line of the steel wire rope of the pulley 10 coincides with the center line of the hanging pan 1, and a hanging hammer 7 is tied under the steel wire rope 6, weighing about 40kg. The center of the hanging hammer 7 coincides with the center of the han...

Embodiment 3

[0034] Such as Figure 4 , Figure 5 As shown, on the basis of Embodiment 2, the pulley mechanism includes a pulley 10 and two steel plates 9, the two steel plates 9 are parallel to each other and the steel plates 9 are all welded on the bottom end surface of the suspension pan 1, and the pulley 10 is arranged on the two steel plates 9 Two bolts 11 are arranged between the steel plates 9, the two ends of the two bolts 11 pass through one of the steel plates 9 respectively, and the two bolts 11 pass through the pulley 10, the pulley 10 can rotate along the axis of the bolt two 11, and the steel wire rope 6 Set on the top wall surface of pulley 10, steel ruler buckle 2 13 is sleeved on the end of bolt 2 11, the top of steel ruler 2 8 is connected with the bottom end of steel ruler buckle 2 13, steel ruler 2 8 is arranged on steel wire rope 6 Between the two ends, steel ruler 2 8 is arranged on the outside of two steel plates 9. Bolt 2 11 is set under the suspension pan. In add...

Abstract

The invention discloses a method for mounting and controlling a large arc structure template and a vertical centring device thereof. The vertical centring device coincides with a central point of a cooling tower, an end portion of a steel tape is fixed on the vertical centring device, the other end of the steel tape is fixed with a template of the cooling tower, a distance is determined after leveling, measurement is performed through the steel tape suspended above a hanging tray, the template is positioned accurately and fixed, distance from the center of the hanging tray to an inner template is calculated, a connecting mechanism is mounted at a top end of the hanging tray, a pulley mechanism is fixed below the hanging tray, a steel rope and a steel tape two are connected with the pulley mechanism, the steel rope is sleeved on an outer wall of the pulley mechanism, an adjusting device and a drop hammer are connected with the steel rope, and the center line of the drop hammer and the center line of the hanging tray are arranged to be on a same line. By the aid of the vertical centring device and a measurement method, the size of an outer template of a barrel wall can be determined and fixed for achieving a purpose of accurately controlling the size of the template, and accurate measurement can also be achieved even with a higher height.

Description

technical field [0001] The invention relates to a method for installing and controlling a large arc-shaped structural formwork and a vertical centering device thereof, which is specially used for controlling the size of an arc-shaped formwork during cooling tower construction. Background technique [0002] The control of the size of the arc formwork during the construction of the cooling tower is generally through a total station, a total station, that is, a total station electronic speed measuring instrument. It is a high-tech measuring instrument that integrates light, mechanics and electricity. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slope distance, horizontal distance) and height difference measurement functions. Because it can complete all the survey work on the station once the instrument is placed, it is called a total station. It is widely used in the field of precision engineering measurement or de...
