Enter U-type groove after card line bolt, rotate coiling apparatus, steel wire is hung down to bottom fixture；
(3) steel wire and plummet are naturally drooped into the location control hole of bottom fixture, stood；
(4) deviation by Steel Ruler measuring steel wire in location control hole, then carries out this deviation and specification
Compare, judge whether siding is tilted and inclined direction this side up, and the verticality of siding is adjusted with this, until reaching
Code requirement.
Tank body top fixture is fixed and is welded at first band siding the top, the tank body bottom fixture steel plate support
Fixation is welded on tank bottom.
The measuring device is arranged on the inside of steel storage tank siding.
Using two groups of measuring devices, the squareness measurement of 90 ° of both directions of tank body angle is respectively used to.
The beneficial effects of the invention are as follows：
(1) this method only needs set of device, you can monitored over time cartridge type steel storage tank hanging down during inverted construction
Straight degree deviation, is adjusted by every two measurements with siding verticality, reduces Accumulated deviation, final verticality is played very
Good control.Without repeatedly setting up measuring instrument, and from site influence.
(2) after two band siding installations are in place, line is fallen from the U-shaped card mouth of top fixture by coiling apparatus and is put down, when
When line pendant arrives at location control hole, plummet is unloaded, steel wire again installs plummet after being pierced by from location control hole.Use two
Position of the direct measuring steel wire of Steel Ruler in location control hole, you can precisely judge perpendicularity deviation value, and as mark
Standard carries out the adjustment of stave sheets, the verticality of storage tank is reached the requirement of higher.
(3) when cartridge type steel storage tank uses inverted construction technology, tank body top fixture and tank body bottom fixture are with weldering
Direct type formula is fixed, and is not required to adjust fixture position as tank body is installed, so as to can ensure that multiple squareness measurement in same side
To raising measurement accuracy.
(4) two groups of measuring devices used are arranged on the inside of steel storage tank siding in this method, reach anti-by siding protection
The effect of wind, avoids the measurement error brought by wind effect.
(5) present apparatus is simple in structure, easy to process, and processing cost is low, is adapted to apply at the construction field (site).

Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, the present invention is used for the device 1 of cartridge type steel storage tank reverse installation process squareness measurement, including tank body
Top fixture and tank body bottom fixture two parts, two parts are connected to become entirety by steel wire 9, and 9 one end of steel wire is equipped with plummet；Institute
State tank body top fixture and fixed thread plate 2 is formed by monolithic steel plate, 2 upper end side of fixed thread plate is provided with a U-shaped notch, fixed thread plate 2
It is equipped with a card line bolt 3；Tank body bottom fixture includes the steel plate with location control hole, described to carry location control hole
Steel plate be equipped with coiling apparatus 7, bearing is arranged below in steel plate.
As shown in Figure 1, two sets of measuring devices are arranged in 0 ° and 90 °, or it is arranged in 180 ° and 270 °.
After first band stave sheets is installed, after having fixed top fixture, using steel wire and plummet from U-shaped card mouth center
Hang down, steel wire is the center such as Fig. 2 in location control hole.
As shown in figure 3, the radius R in location control hole is determined that cartridge type steel storage tank is according to specification pair by specification
It is mostly 4H/1000 in the deviation of verticality and is not more than 30mm.Illustrate so that certain tank body highly reaches 40m as an example, using radius R=
The location control hole of 30mm.And positioning sample punching is stamped on the four corners of the world direction in location control hole.
Vertical survey is carried out in two steps：Substep is carried out with the H (tank skin height) of critical altitude 4H/1000=30：
1st, when siding setting height(from bottom) is less than H, judged by deviation of the measuring steel wire in location control hole, be
It is no to need to adjust.If necessary to adjust, using position of two direct measuring steel wires of Steel Ruler in location control hole, water is read
Square to deviation X, vertical direction deviation Y value can judgment bias direction and deviation, be adjusted.
2nd, when siding setting height(from bottom) is more than H, by observing steel wire whether inside location control hole, you can judge whether
Need to adjust.If steel wire encounters the hole wall in location control hole, improved using coiling apparatus to the fixture steel plate of bottom
2mm or so, measurement and positioning control hole center to the distance of plummet bottom, judges outgoing direction, is adjusted.
Cartridge type steel storage tank squareness measurement construction technology implementation：
This method is described further with reference to Fig. 2 cartridge type steel storage tank vertical survey devices, to its implementation and behaviour
Done as process with explanation：
The first step：Top clamp and bottom clamp are made, top clamp is installed to 0 ° of side of first band siding upper end
On bit line, using preprepared steel wire plummet, have from the U-shaped card on top and steel wire plummet hangs down, determine location control
Hole center, using high-accuracy water leveling ruler to bottom fixture base levelling, fixes top, bottom fixture.
Second step：Coiling apparatus is fixed on the steel plate of bottom fixture upper surface, by the roller bearing of coiling apparatus by steel wire
By entering U-type groove after card silk bolt, coiling apparatus is rotated, steel wire is hung down to bottom fixture.
3rd step：Steel wire and plummet are naturally drooped into the location control hole of bottom fixture, stood.
4th step：Deviation of the measuring steel wire in location control hole is measured by Steel Ruler, then by this deviation with
Specification is compared, and judges whether siding is tilted and inclined direction this side up, and the verticality of siding is adjusted with this,
Until reaching code requirement.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
