Concealment acceptance, bolt hole on built-in fitting steel plate mix flax silk blocking sealing with butter, to built-in fitting bottom steel when casting concrete
The intensive position of muscle carries out vibration compacting, and vibrating spear is avoided to contact and touch the support frame for playing built-in fitting, pays attention to checking pre-embedded steel slab
Positions and dimensions, discovery loosen in time stop concrete vibrating simultaneously rebuild immediately, should ensure that on steel plate has enough concrete
It is overflowed from extravasating hole, and taps steel plate using tool, there is bubble-free to judge according to observation extravasating hole, in concrete initial set
To final set must not someone trample or tap built-in fitting plate face, be poured concrete and clear up the concrete on built-in fitting surface in time
Completely, concrete conserves in time after being poured 12 hours, the concrete laitance on embedded part surface should be polished after 24 hours clean,
And check Forming Quality；
E it) inspects for acceptance: checking whether built-in fitting lower part concrete is closely knit, by hollowing position mark, then utilize air compressor machine
Pressure fills the treatment measures such as resin, and designation equipment installation control line and absolute altitude on pre-buried center target, drawing set finer wire, multiple
Whether center line, the absolute altitude of core built-in fitting meet the requirements.
According to the above scheme, the step B) in further include following content: positioning must be measured before welding bracing frame
Setting-out work, when unwrapping wire, should play the line of ink marker on bedding plane or concrete surface, and center line need to be coated on measurement coil holder, and center line should be drawn
The finer wire of good diameter 0.5mm, for both ends bolt on the support frame of welding, support frame should carry out absolute altitude, gradient after welding
It checks.
According to the above scheme, the step C) in four arm of angle of the lower steel plate welding of built-in fitting adjust bolt, while supporting
The corresponding position weld horizontal of frame adjusts bolt, and weld locations indwelling is correct, prevents the installation for hindering built-in fitting lower steel plate
In place.
According to the above scheme, the step C) in the fine tuning of angle is carried out using slope gage, level should be utilized after fine tuning is good
Review inspection is carried out to upper and lower steel plate inclined-plane upper, middle and lower portion absolute altitude, axis is checked using theodolite.
The beneficial effects of the present invention are: 1, a kind of construction method of installation of I-shaped inclined-plane built-in fitting of large size is provided, it is whole
Good, the quick construction of property, shortens the integral construction duration；2, the adjustment of levelness, angle, middle line is carried out by adjusting bolt, is protected
The installation quality of built-in fitting is demonstrate,proved.

Specific embodiment
For a better understanding of the invention, the invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1-3, a kind of construction method of installation of the I-shaped inclined-plane built-in fitting of large size, comprising the following steps:
(1) built-in fitting makes: processing several bolts hole 3 on upper steel plate 1 and lower steel plate 2, and passes through several through spiral shells
Bolt pipe 4 is connected, and processes several extravasating holes 5 close to the position of bolt hole on upper and lower steel plate, and built-in fitting usually makes in processing factory,
Since steel plate is deformed by that can generate larger stress when cutting, welding anchor rib hole to be provided, once deformation should be first corrected
Dowel is welded again, this built-in fitting uses 30mm thick steel plate, cannot weld with plant bottom case contact surface, embedded part surface roughness requirements
For Ra=3.2, therefore Milling Machining is carried out to surface of steel plate, it is ensured that design requirement, the built-in fitting surface processed belong to
Polished surface must not collide surface of steel plate in transportational process.Prevent to guarantee not corroding to smear anti-corrosive grease or brush one layer of red lead
Rust paint；
(2) support frame is installed: built-in fitting weight is big, the fashioned iron welding that support frame must be big using rigidity, and welding first is vertical
Bar 6, upright bar foot are welded on the built-in fitting or reinforcing bar on bedding plane or concrete surface, guarantee that support frame will not slide deformation；Its
Secondary welding cross bar and diagonal brace 9, sheer pole 8 directly bears lower steel plate, therefore absolute altitude is had to accurately, and cross tube 7 bears upper steel plate
Upper sheer pole should be welded into inclined-plane when welding, and line setting work must be measured before welding bracing frame, when unwrapping wire should bullet
The line of ink marker is in bedding plane, and center line need to be coated on measurement coil holder, and center line should draw the finer wire of diameter 0.5mm, and both ends bolt is welding
On the support frame connect, support frame should carry out the inspection of absolute altitude, gradient after welding, and avoid the occurrence of biggish error and be difficult to adjust
Solution is applied on crane lifting built-in fitting to support frame after qualified support frame welding, since installation of embedded parts is pacified at inclination
Dress, should shore securely in side, prevent from collapsing；
(3) installation of embedded parts: support frame installs the installation that built-in fitting should be carried out after acceptance(check), and installation uses crane
Lifting is in place, then is finely adjusted, and hoisting process must protect upper surface not to be scratched, first in four arm of angle of the lower steel plate of built-in fitting
Welding adjusts bolt, while adjusting bolt in support frame side weld horizontal, and weld locations indwelling is correct, prevents from hindering built-in fitting
Lower steel plate it is in place, installation process must use slope gage to carry out the fine tuning of angle, should be using level to upper and lower steel after fine tuning is good
Plate inclined-plane upper, middle and lower portion absolute altitude carries out review inspection, and axis is checked using theodolite；
(4) before casting concrete process, template inspection, reinforcing bar and built-in fitting concreting: concreting: are carried out
Concealment acceptance, bolt hole on built-in fitting steel plate mix flax silk blocking sealing with butter, to built-in fitting bottom steel when casting concrete
The intensive position of muscle carries out vibration compacting, and vibrating spear is avoided to contact and touch the support frame for playing built-in fitting, pays attention to checking pre-embedded steel slab
Positions and dimensions, discovery loosen in time stop concrete vibrating simultaneously rebuild immediately, should ensure that on steel plate has enough concrete
It is overflowed from extravasating hole, and taps steel plate using tool, there is bubble-free to judge according to observation extravasating hole, in concrete initial set
To final set must not someone trample or tap built-in fitting plate face, be poured concrete and clear up the concrete on built-in fitting surface in time
Completely, concrete conserves in time after being poured 12 hours, the concrete laitance on embedded part surface should be polished after 24 hours clean,
And check Forming Quality；
(5) it inspects for acceptance: checking whether built-in fitting lower part concrete is closely knit, by hollowing position mark, then utilize pneumatics
Machine pressure fills the treatment measures such as resin, and designation equipment installation control line and absolute altitude on pre-buried center target, drawing set finer wire,
Whether center line, the absolute altitude of review built-in fitting meet the requirements.
Beneficial effects of the present invention are mainly: this construction method constructing operation is convenient, and construction quality is easy to guarantee, construction machine
It is simple to have equipment, plane of constructing and space hold are few, and construction personnel's demand is few.By optimization production, mounting process, according to this
The process flow of method and quality control method are implemented so that built-in fitting is successfully installed, can solve the deformation of built-in fitting surface warp,
The requirement of roughness achieves good installation effect.
