Difference, is adjusted by the measurement of every two band wallboard perpendicularity, decreases Accumulated deviation, and final perpendicularity serves well control
System.Without repeatedly setting up measuring instrument, and not by site influence.
(2) after two band wallboards installations are in place, by coiling apparatus, line pendant is put down from the U-shaped bayonet socket of top fixture, work as line
When pendant arrives at location control hole, being unloaded by plummet, plummet is installed after passing from the control hole of location by steel wire again.Use two
Steel Ruler direct measuring steel wire position in the control hole of location, can precisely judge perpendicularity deviation value, and enter as standard
The adjustment of row stave sheets, makes the perpendicularity of storage tank reach higher requirement.
(3) when cartridge type steel storage tank uses inverted construction technology, tank body top fixture and tank body bottom fixture are all to weld pattern
Fixing, it is not required to install along with tank body and adjust fixture position, thus can ensure that repeatedly squareness measurement, all in same direction, improves
Certainty of measurement.
(4) in this method, two groups of measurement apparatus used are arranged on inside steel storage tank wallboard, reach windproof effect by wallboard protection
Really, it is to avoid the measure error brought by wind effect.
(5) this apparatus structure is simple, be prone to processing, and processing cost is low, is suitable for applying at the construction field (site).

Detailed description of the invention
Describe the present invention below in conjunction with the accompanying drawings.
As shown in Figure 1-2, the present invention is for the device 1 of cartridge type steel storage tank reverse installation process squareness measurement, including tank body top card
Tool and tank body bottom fixture two parts, two parts are connected to become entirety by steel wire 9, and steel wire 9 one end is provided with plummet；Described tank
Body top fixture is formed fixed thread plate 2 by monolithic steel plate, and side, fixed thread plate 2 upper end is provided with a U-shaped breach, on fixed thread plate 2
It is provided with a card line bolt 3；Described tank body bottom fixture includes the steel plate with location control hole, described with positioning control hole
Steel plate is provided with coiling apparatus 7, and steel plate is arranged below bearing.
As it is shown in figure 1, two set measurement apparatus are arranged in 0 ° and 90 °, or it is arranged in 180 ° and 270 °.
After installing the first band stave sheets, after having fixed top fixture, steel wire and plummet is used to hang down from U-shaped bayonet socket center,
Steel wire is center such as Fig. 2 of location control hole.
As it is shown on figure 3, location control hole radius R determined by specification, cartridge type steel storage tank according to specification for hang down
The deviation of straight degree mostly is 4H/1000 and no more than 30mm.Reach by certain tank body height and illustrate as a example by 40m, use radius R=30mm
Location control hole.And on the direction, the four corners of the world of location control hole, stamp positioning sample punching.
Vertical survey is undertaken in two steps: carry out step by step with the H (tank skin height) of critical altitude 4H/1000=30:
1, when wallboard setting height(from bottom) is less than H, judged by measuring steel wire deviation value in the control hole of location, if
Need to adjust.If needing to adjust, use two direct measuring steel wire of Steel Ruler position in the control hole of location, reading horizontal
Deviation of directivity value X, vertical direction deviation value Y value get final product judgment bias direction and deviation value, are adjusted.
2, when wallboard setting height(from bottom) is more than H, by observing whether steel wire is positioning inside control hole, i.e. can determine whether to need
Adjust.If the hole wall of location control hole encountered by steel wire, coiling apparatus is used to be improved 2mm to the fixture steel plate of bottom
Left and right, the distance bottom measurement and positioning control hole center to plummet, it is judged that direction, it is adjusted.
Cartridge type steel storage tank squareness measurement construction technology implementation:
This method is described further, to its implementation and operating process with reference to Fig. 2 cartridge type steel storage tank vertical survey device
Do with explanation:
The first step: make top dop and bottom dop, installs 0 ° of rhumb line to the first band wallboard upper end by top dop
On, use preprepared steel wire plummet, from the U-shaped fixture on top, steel wire plummet is hung down, determine in the control hole of location
Heart position, uses high-accuracy water leveling ruler to bottom fixture base levelling, fixes top, bottom fixture.
Second step: be fixed on by coiling apparatus on the fixture upper surface steel plate of bottom, by the roller bearing of coiling apparatus by steel wire by card
Enter U-type groove after silk bolt, rotate coiling apparatus, make steel wire hang down to bottom fixture.
3rd step: steel wire and plummet are naturally drooped to the location control hole of bottom fixture, stands.
4th step: measure measuring steel wire deviation value in the control hole of location by Steel Ruler, then this deviation value is entered with specification
Row comparison, it is judged that wallboard is in the direction whether this side up tilts and tilt, and adjusts the perpendicularity of wallboard with this, until reaching
To code requirement.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as this
Bright protection domain.
