Description
Technical field
The present invention relates to the sleeve installation methods in a kind of apparatus foundation bolt Embedment Construction, specifically, being a kind of T-type
The integral sleeve installation method of the diameter of bolt≤48mm.
Background technology
The foundation bolt of partial metallurgical industrial equipment is detachable, i.e., foundation bolt is not directly to be anchored at basic coagulation
In soil, but it is anchored in T-bolt sleeve（" T-bolt sleeve " hereinafter referred to as " sleeve "）, sleeve with basis construct together,
It is directly anchored in basis, until installing equipment just by T-bolt insertion sleeve, T-bolt can be from when equipment replacement
Dismounting in sleeve.
T-bolt top is screw rod, and bottom end is T connector, and what is configured with it is the sleeve with anchor plate, leans on T connector and anchor
Anchor force between solid plate, to install fastening apparatus.Shape after equipment installation is as shown in Figure 1, the figure that wherein black lines form
Shape is the component that T-bolt and integral sleeve are constituted, construct foundation of civil work when, first that sleeve is pre-buried, T-bolt is pacified in equipment
The dress stage just anchors into sleeve.
T-bolt sleeve assembly installs basic demand：Card slot coincide good only among T connector and anchor plate, anchors
Face contact is close, could uniform force, if T connector is contacted with anchor plate for line, or even only point contact when, bolt locally by
Power can seriously affect the service life.Therefore sleeve installation verticality it is necessary≤l/1000, namely anchoring plate face levelness it is necessary≤
1/1000, bushing core deviation controls within 5mm（The centre deviation of T-bolt is 2mm）.Therefore T-bolt sleeve is improved
Pre-buried precision be the key that T-bolt integral sleeve installation.
Chinese patent CN102080417 B disclose that large-scale T types sleeve bolt fission is embedded to be applied on May 23rd, 2012
Work method, including：Embedded iron parts are set on bed course, the installation bolt fixed frame above embedded iron parts；Confirm in bolt
After the heart controls point, anchor plate is welded on bolt fixed frame；Anchoring box is welded in anchor plate bottom；Again check anchor plate and
Bolt collar is lifted after anchoring box position, firm welding after bolt collar is aligned really with anchoring board group；T type shanks of bolt are lifted,
The T types head of T type shanks of bolt and anchoring crab bolt are fixed, upper weld sleeve cap；Sundries around bolt is cleared up, checks weldering
Quality is connect, bolt location is checked, construction finishes.Although the technical solution has reached raising work efficiency, supplies consumption is reduced
With the purpose for reducing construction cost, but the pre-buried precision of its T-bolt sleeve is not fully up to expectations.
Therefore known T type sleeve bolt fission burial and construction methods there are problems that it is above-mentioned various inconvenient and.
Invention content
The purpose of the present invention, be to propose a kind of T-bolt diameter using two sets of mutual independent fixing support racks≤
The integral sleeve installation method of 48mm.
To achieve the above object, technical solution of the invention is：
A kind of integral sleeve installation method of Equipment Foundations T-bolt diameter≤48mm, it is characterised in that including following
Step：

（3）In order to facilitate checking and detect, base center benchmark busbar is launched on coil holder crossbeam and indentation is marked, is used
Bracing wire is stuck in the indentation of both ends 24# wires respectively, and the center line in length and breadth that benchmark bus-bar frame pull-up in base center is set is installation
The benchmark of sleeve, before detecting sleeve positioning every time, need to use plumb bob at the indentation hanging wire alignedly on red warning triangle, review
Confirm that benchmark busbar does not move；
C, installation sleeve centre of location sub-line frame
Center sub-line is the reference for installation of every group of T-bolt sleeve, on the basis of the busbar of the Equipment Foundations center, from
Longitudinal and transverse two directions draw the centre of location sub-line of every group of sleeve, making, installation center sub-line holder at center sub-line both ends,
Equally in center sub-line rack beam upslide central point indentation for the steel wire that stretches tight；The production method and benchmark of the center sub-line frame
Busbar coil holder is identical；
D, T-bolt housing supports frame is installed
Using the preset ironware in step a as fixed pivot, on the basis of the center sub-line in step c, with steel upright bar and steel
Horizon bar, the above reinforcing bars of φ 20mm make reinforcing bar diagonal brace, install T-bolt housing supports frame, and first spot welding waits for that T-bolt sleeve is pacified
Adjustment it is whole it is accurate after weld, several T-bolt sleeve groups are set and make an integrated support frame, supporting rack must independently of steel reinforcement cage and
Form bracing system；
E, T-bolt sleeve install and detect, repetition measurement
Before the installation of T-bolt sleeve, end face center line suitable for reading is checked, if not provided, in need to first dividing and putting in " cross "
Separated time；Then the steel wire of " cross " middle separated time alignment centre of location sub-line frame pull-up on each T-bolt sleeve is in place, and
Messenger wire pendant confirms T-bolt sleeve verticality, by T-bolt sleeve and T-bolt housing supports frame tie point after meeting the requirements
Firm welding；Before casting concrete, to T-bolt bushing core deviation, T-bolt sleeve verticality 1/1000, T-bolt mark
High ﹢ 20mm carry out repetition measurement, and repetition measurement must be since benchmark busbar again successively to centre of location sub-line, T-bolt sleeve repetition measurement, nothing
Dismantle steel wire after accidentally, center sub-line frame still needs to retain, after casting concrete finishes initial set, then successively base center busbar,
Center sub-line frame pulls up steel wire, checks the sleeve centre of location, is corrected immediately as deviated caused by vibrating.
The integral sleeve installation method of T-bolt diameter≤48mm of the present invention can also use technical measures below
To further realize.
Method above-mentioned, wherein in the step a, the ironware on plank sheathing first must weld a supporting rack on ironware and use
Angle clip, in order to avoid bake bad wooden model when rear weldering.
Method above-mentioned, wherein centre deviation≤5mm of the T-bolt sleeve.
After adopting the above technical scheme, the integral sleeve installation method of T-bolt diameter≤48mm of the present invention has
Following advantages：
1, installation steps reasonable design, easy to operate；
2, two sets of mutually independent support fixed systems are installed, a set of benchmark bus-bar frame as construction survey is another
Cover the supporting rack as installation sleeve fixation, it is ensured that the installation accuracy and measurement accuracy of sleeve；
3, ensure that the pre-buried precision of T-bolt sleeve, the verticality of sleeve installation reach≤l/1000, namely anchoring plate face
Levelness reach≤1/1000, bushing core deviation controls within 5mm.
