Description
Technical field
The present invention relates to Steel Structure Installation, be specifically related to a kind of H profile steel beam docking node locating installation method.
Background technology
Steel Structure Installation would generally relate to the erection stage of various section steel beam and support, the characteristic in this stage
It is that substance is little, radix is big, step is more in installation, expends the time long.At present, section steel beam and supporting uses isostructural installation more
Hoisting machinery coordinates lifting, then it is fixing to be responsible for structure connection by installation personnel.Due to the steel construction cycle when lifting is located by connecting
Longer, hoisting machinery stays cool during this period, it is impossible to gives full play to hoisting machinery feature rapidly and efficiently, not only increases
Construction uses the cost of crane, and constrains installation progress.
It addition, steel construction is in installation process, the link that is located by connecting is the longest one procedure, and this operation includes tying up
Tie up and hang, be accurately positioned, fix temporarily, reinforce the steps such as perfect, off the hook decoupling device, wherein the longest time-consuming temporarily anchoring to exactly
Link is improved in reinforcing.In interim fixing link, for realizing the simplicity of operation, take to weld temporary support or direct spot welding more
Mode, the most later carry out the cleaning work of excess surface support and overlap to installing the later stage, but this type of work exist certain
The danger factors such as construction quality and processing safety；In link is improved in reinforcing, some uncertain factors often occur (as pressed
More solito program now coordinates the hoisting machinery of installation to be substantially at stagnation waiting state: as between girder steel element and connecting plate
How with bolts connecting, girder steel element is more with the bolt hole offered on connecting plate, the time expended that overlaps is long, and lifting
Time girder steel element rock, add the difficulty to hole), constrain the continuity of its operating process, whole installation process is taken
Between cannot accurately estimate.
Summary of the invention
It is an object of the invention to, for the deficiencies in the prior art, it is provided that the H profile steel beam docking node in hole, a kind of quick school
Locating mounting method.
The technical solution used in the present invention is: a kind of H profile steel beam docking node locating installation method, specifically includes following step
Rapid:
Step one, the web both sides of girder steel one pre-install connecting plate, a part for connecting plate is overlapping with the web part of girder steel one,
The bolt hole offered on connecting plate is directed at the bolt hole offered on girder steel one web；
Step 2, girder steel one handling is docked at girder steel two, make the levelness on both edges of a wing keep consistent, web
Perpendicularity keeps consistent；Gap is left between girder steel one and girder steel two butt end；Launch connecting plate, another of connecting plate simultaneously
Part is overlapping with the web of girder steel two；
Step 3, offer positioning installation apparatus, described positioning installation apparatus includes adjustment structure and snap fastener, governor motion bag
Including the first adjustment seat, the second adjustment seat and adjusting rod, the first adjustment seat is connected with one end of adjusting rod, the other end of adjusting rod with
Second adjustment seat connects, and the closure of the length direction of adjusting rod and two girder steels is consistent；Snap fastener includes fixing card body,
