Description
Technical field
The present invention relates to a kind of methods that sole plate centering is levelling, the especially levelling side of cold box foundation bottom plate centering
Method.
Background technique
Existing cold box foundation bottom plate is levelling, centering method be usually use parallels on the basis of to carry out centering levelling,
But the levelling method of this centering not can solve when no shearing resistance slot or basis are too low, parallels installation group number is permitted more than national regulation
Perhaps when range, the higher cost of installation foundation bottom plate.
Summary of the invention
The purpose of present invention is to solve higher cost existing for the levelling method of existing cold box foundation bottom plate centering
The problem of, and the method that a kind of provide time saving, laborsaving save the cost cold box foundation bottom plate centering is levelling.
In order to complete present invention purpose, the application uses following technical scheme:
A kind of levelling method of cold box foundation bottom plate centering of the invention, sole plate are straight not at one by least three
Screw rod on line is supported on grouting face, from top to bottom, be sequentially arranged on each screw rod top nut, backing plate, lower nut and
Sole plate, lower nut are placed on sole plate, and sole plate and backing plate are sleeved on screw rod, top nut and lower nut and spiral shell
Bar be threadedly coupled, in which: the levelling method of cold box foundation bottom plate centering the following steps are included:
(a), one section of angle bar is welded between each sole plate and backing plate, the bottom end of the angle bar and sole plate weld
Together, two sides of angle bar weld together with backing plate；
(b), a level is set up on grouting face, finds a construction reference point, scale is placed vertically upper
It states on construction reference point, measures construction reference point to the vertical range between level, then successively by scale with level
It is moved on three positions of sole plate, and scale is placed on three positions of sole plate with being respectively perpendicular, use water
Quasi- instrument is measured respectively on above three position, and sole plate is to the vertical range between level, by being calculated
The absolute altitude of sole plate on above three position, if above three absolute altitude does not reach design requirement, by adjusting at least three
Position of a lower nut on screw rod, so that the absolute altitude of sole plate reaches design requirement on above three position, then,
Top nut is tightened on backing plate, that is, the centering for completing sole plate is levelling.
The levelling method of a kind of cold box foundation bottom plate centering of the invention, in which: three positions are not in straight line
On.
The levelling method of a kind of cold box foundation bottom plate centering of the invention, in which: three positions are passing through base respectively
Near three screw rods of plinth bottom plate.
The levelling method of a kind of cold box foundation bottom plate centering of the invention, in which: after step (b) further include: will be in the milk
Face back-grouting, after the completion of being in the milk, in the state that sole plate no longer sinks, removal is welded on backing plate and sole plate
Angle bar.
The levelling method of a kind of cold box foundation bottom plate centering of the invention, in which: the screw rod is four, they distinguish cloth
It sets on four angles of sole plate.
The levelling method of cold box foundation bottom plate centering of the present invention is not only easy but also easily operated, it is not only time saving and energy saving but also save at
This, can also solve when no shearing resistance slot or basis are too low, when parallels installation group number is more than national regulation allowed band, how to base
Plinth bottom plate carries out the levelling problem of centering.
Detailed description of the invention
Fig. 1 is that the structure in the levelling method of cold box foundation bottom plate centering of the present invention is bowed to schematic diagram；
Fig. 2 is the diagrammatic cross-section at the A-A of Fig. 1, for the sake of clarity, level drawn in the figure；
In fig. 1 and 2, label 1 is angle steel, label 2 is screw rod, label 3 is top nut, label 4 is backing plate, label 5
For lower nut；Label 6 is basic bottom plate；Label 7 is level；Label 8 is scale；Label 9 is grouting face.
As depicted in figs. 1 and 2, sole plate 6 is supported on grouting face 9 by four screw rods 2 not point-blank
On, screw rod 2 is arranged on four angles of sole plate 6, from top to bottom, be sequentially arranged on each screw rod 2 top nut 3,
Backing plate 4, lower nut 5 and sole plate 6, lower nut 5 are placed on sole plate 6, and sole plate 6 and backing plate 4 are sleeved on screw rod 2
On, top nut 3 and lower nut 5 are threadedly coupled with screw rod 2.
The levelling method of cold box foundation bottom plate centering of the invention the following steps are included:
(a), one section of angle bar 1, the bottom end of the angle bar 1 and sole plate are welded between each sole plate 6 and backing plate 4
6 weld together, and two sides and the backing plate 4 of angle bar 1 weld together；
(b), a level 7 is set up on grouting face 9, finds a construction reference point, scale 8 is placed vertically
On above-mentioned construction reference point, construction reference point is measured to the vertical range between level 7, then by scale 8 with level 7
It is successively moved on three positions of sole plate 6, not point-blank, they are passing through basis respectively for above three position
Near three screw rods 2 of bottom plate 6, and scale 8 is placed on three positions of sole plate 6 with being respectively perpendicular, with level 7
It is measured on above three position respectively, the vertical range between sole plate 6 to level 7, by being calculated upper
The absolute altitude of sole plate 6 on three positions is stated, if above three absolute altitude does not reach design requirement, by adjusting four lower spiral shells
Position of the mother 5 on screw rod 2, so that the absolute altitude of sole plate 6 reaches design requirement on above three position, it then, will
Top nut 3 is tightened on backing plate 4, that is, the centering for completing sole plate 6 is levelling；
