Installation method.
Background technology
As scientific and technical is developed rapidly, the particularly manufacturing appearance of weight equipment, to meet manufacturing technique requirent,
Ensure installation accuracy, not only precision prescribed is high for the built-in fitting on many large equipment bases, and quantity is more, size is big, weight
Weight, this requires the measure of fixation to ensure the accurate of position and absolute altitude, virtually brings some technologies to scene
Problem.Traditional embedded part installation method is to do support below embedded part in advance（Use shaped steel）Or branch is buried in basis in advance
Frame, stress and the fixed embedded part of regulation, but such case often basic score two-step pouring shaping is supported by support, for the first time
Support is buried when pouring.But particularly in some cantilevered structures（Such as bracket）Upper and reinforcing bar is intensive, structural requirement quality compared with
Height, casting concrete must one-shot forming when not allowing to occur construction joint, it is often internal without sufficient space and support stress point
Do support.

Part.
The installation method of cantilever design high-accuracy built-in fitting of the present invention, materials aspect, make it is simple, be easy to grasp, repeat
Using, install, convenient disassembly, while safe and reliable, cost-effective, effect is significant.It is particularly suitable for having been applied by technogenic influence
Work finish around it is above ground level（Relative）Basis, wall, and the capital equipment basis embedded part that centre is not constructed（It is such as large-scale
The weight equipments such as forging press basis）Or the basic embedded part in the box foundation or deep basal pit with basement is installed and reinforcing bar
The intensive field for needing one-time formed quality requirement high.
The present invention is disengaged by with base matrix, does not set support in basic internal, and in basic both sides（Or surrounding）, profit
Main beam is set as the strong point with the built basis of surrounding or other structures etc., main beam lower section passes through pull bar and embedded part phase
Even, embedded part " suspension " is got up and the basic relatively independent precision for separating, embedded part being controlled by the adjusting nut above pull bar.
The installation method of cantilever design high-accuracy built-in fitting of the present invention, not only embedded part installation is not close by basic space reinforcing bar
The influences such as collection, construction concrete vibrating vibrations, and the operation adjustment above basis, easy construction.Avoid conventional mounting pre-
The adjustment inconvenience that exists during embedded part, precision is relatively low, qualification rate is overproof, do over again often, input cost is higher, construction period compared with
Greatly, number of drawbacks and the deficiency such as waste time and energy.
