Description
Technical field
The present invention relates to spring vibration-isolated foundation technical field of construction, a kind of spring vibration-isolated foundation construction formwork of specific design is adjusted
Leveling device and its construction method.
Background technology
At present, for the industrial premises large scale equipment using high-rating generator, widely used spring vibration-isolated foundation.The basis
Form is mainly on generator between basic top platen and lower support structure and sets a number of Vertical Spring vibration isolator,
So that vibration major part when generating set runs is isolated by spring vibration-isolator, it is unlikely to produce influence to surrounding structure.Spring
The work progress of shock insulating foundation is the basic column cap for first performing substructure, and it be in initially contraction state to be placed on basic column cap
Spring vibration-isolator, and the temporary support framework contour with spring vibration-isolator is performed around spring shock-absorber, afterwards interim
The glued board of platform end template based on being set up in support frame, and steel plate is ridden upon into glue in the surface of spring vibration-isolator
On plywood, relevant position of the glued board at the top of spring vibration-isolator is provided with opening, so that the top of spring vibration-isolator is straight with steel plate
Contact, then casting concrete performs basic platform.When corresponding construction all reaches design strength, and all of motor etc.
After upper load is applied to basic platform, all of spring vibration-isolator is discharged, spring vibration-isolator is undertaken the load on top,
And remove temporary support framework.
During this, the flatness of basic platform template is not more than 1mm/1000mm on code requirement.In order to reach this
One standard, it is desirable to which the flatness of temporary support frame roof should also reach same standard.But traditional temporary support mode
Steel frame is not used, causes the flatness of basic platform template not reach requirement, and rigidity is relatively low, construction quality does not reach guarantor
, there is serious potential safety hazard in card.
The content of the invention
To solve the above problems, the present invention provides a kind of spring vibration-isolated foundation construction formwork levelling device and its construction party
Method, the device can guarantee that the flatness of foundation forms, it is ensured that construction quality.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of spring vibration-isolated foundation construction formwork levelling device, including some vertical supportings, some horizontal supports and some
The leveling lumps of wood, the vertical supporting is located at foundation columns angle outside in front, and the two ends of the horizontal support are described vertical with adjacent
Support is fixedly connected, and each horizontal support forms the horizontal frame of closure, and the tune of some splicings is paved with the horizontal frame
Square wood, the flatness of the leveling lumps of wood is not more than 1mm/1000mm, glued board, the glue is placed on the leveling lumps of wood
The steel plate of top platen bottom based on being placed on plywood, the glued board along being provided with opening on the inside of the horizontal frame, with
Make the top of spring vibration-isolator and the steel plate directly contact；By the flatness for ensuring the leveling lumps of wood, it is ensured that basis is flat
The flatness of platform template.
For temporary support framework, in order to undertake enough loads, it is necessary to possess larger rigidity；But this just leads
Cause when flatness is unsatisfactory for requiring, it is not easy to be adjusted.The flatness of the leveling lumps of wood is easy to adjustment, therefore in horizontal support
The upper laying leveling lumps of wood can be very good to solve the levelling problems of flatness.But the elastic modelling quantity of the lumps of wood is relatively low, for entirety
The lumps of wood of structure easily produces uneven deformation, nor easily overall flatness is controlled because dimensional effect
System.The leveling lumps of wood is set to the leveling lumps of wood of the splicing of some small sizes, levelling device is overcome and is necessary for holistic skill
Art prejudice, had both reduced the dimensional effect of the lumps of wood, the leveling control of flatness was facilitated again, so that flatness is guaranteed.
Additionally, horizontal frame is not easy to be connected with glued board, and the leveling lumps of wood can easily realize the connection with glued board, therefore adjust
Square wood may also operate as connecting the effect of horizontal frame and glued board.
The surface smoothness of the horizontal support is not more than 1mm/1000mm.
If can ensure that the surface smoothness of horizontal support, the flatness of levelling device is may further ensure that, raising is applied
Working medium amount.
The vertical supporting and horizontal support use I-steel.
Vertical supporting and horizontal support use I-steel, have enough rigidity to ensure the stabilization of structure, while convenient material drawing,
Save cost.
The vertical supporting uses scaffold tubes, the horizontal support to use I-steel.
The trick pipe top is provided with the regulation jackscrew of threaded connection.
Regulation jackscrew is provided with, the height of vertical supporting can be conveniently adjusted, is easy to the substantially leveling of horizontal support.
The spacing of the vertical supporting is not more than 400mm, is respectively arranged in the outside of the basic column cap, the level branch
Hem width goes out the basic column cap surrounding 50mm in support frame frame.
The spacing of vertical supporting is not more than 400mm, it can be ensured that support frame has enough rigidity to undertake upper load, and
By deformation amount controlling within the specific limits, it is ensured that construction quality.
A kind of construction method of spring vibration-isolated foundation construction formwork levelling device, comprises the following steps：
Step 1：Vertical supporting is set up in setting position；
Step 2：Perform horizontal support at setting absolute altitude at the top of the vertical supporting, the two ends of the horizontal support with
The adjacent vertical supporting is fixedly connected；
Step 3：The leveling lumps of wood is laid on the horizontal support；
Step 4：Glued board and steel plate are set up on the leveling lumps of wood, top basic platform is poured.
Wherein, in step 1, the vertical supporting is scaffold tubes, and regulation jackscrew is provided with the top of the scaffold tubes；By adjusting
Section jackscrew determines the absolute altitude at the top of the trick pipe.
In step 2, the absolute altitude of the horizontal support is found accurately using spirit level, the horizontal support is carried out using horizon rule
It is levelling.
In step 3, the leveling lumps of wood and the glued board of the upper bottom of foundation are fixedly connected.
Beneficial effects of the present invention are：
The present invention substantially increases spring vibration-isolated foundation template flatness, improve isolation spring installation quality, it is to avoid flat
Whole degree is not reached and requires that the device damage for causing even cannot run phenomenon, is carried in engineering economy with construction period
Rise.
