Description
Technical field
The present invention relates to a kind of Steel corridor bracket support adjustment steel plate system and its installation methods.
Background technique
Multilayer support Steel corridor promoted it is in place before, in order to avoid multilayer support is marked vertically and transversely and horizontally in space
Steel construction error of the Gao Yin in specification allowed band is excessive, causes each Bearing Seat Force unbalanced, according to Construction of Steel Structure specification
It is required that needs should carry out on steel concrete bracket, structure is levelling, and back-grouting places monolith steel after the completion of being typically employed in bracket structure
The levelling method of plate.
However, bracket planar dimension is larger, steel plate heavier-weight, manual operation upper air installing can not be completely secured steel plate and exist
After installation, the horizontal absolute altitude error of multilayer bracket is in controlled range, and support installation region is only positioned at one of entire bracket
Point, so needing to carry out levelling to standoff region, the absolute altitude of support is adjusted by the way that multiple control points are arranged in standoff region,
If padding monolith steel plate at support, accurate adjustment absolute altitude cannot achieve, while also resulting in the waste of material, and support is in place
Required precision in the process is relatively high, and different branch block errors are controlled substantially in 1cm or so, and same support control pads monolith in 3mm
Steel plate is unable to satisfy required precision, if construction wrong, especially it is difficult to unload itself high altitude operation in place for high-altitude vestibule across steel greatly
Degree is big, security risk is high, and quality control on construction is difficult.
In addition, causing local bracket end reaction after unloading in place excessive because absolute altitude is inconsistent, there is peak value, by anti-
Promote pading plate unloading again to adjust end reaction, difficulty is very big, and safety wind is dangerous high.
