Abstract
Aiming at the problems of high requirement for installation positioning accuracy, long construction period and easiness in generating a large plane size deviation, which are caused by the case that all sections of curtain wall main frames adopt a spare part installation mode in the prior art, the invention provides an installation method for trusses of the curtain wall main frames. The installation method comprises: arranging embedded parts for installing a first section of curtain wall main frame on a required floor structure, and prefabricating sheet unit structures for composing a second section of curtain wall main frame and above section of curtain wall main frame in a factory; installing the first section of curtain wall main frame in the spare part installation mode; from the second section of curtain wall main frame, assembling the second section of curtain wall main frame and the above section of curtain wall main frame by adopting the sheet unit structures in a sheet installation mode. Measurement on three-dimensional positions of uprights and cross bars, which are required by the spare part installation mode, can be effectively reduced; measurement workload is effectively reduced; moreover, the sheet unit structures prefabricated in the factory are high in accuracy; curtain wall glass is guaranteed to be installed between the adjacent cross bars in a vertical plane where the sheet unit structures are positioned.
Description
Technical field
The invention belongs to high-rise building building technology field, relate generally to a kind of curtain wall main frame and become Pin installation method.
Background technology
At present, the installation method of high-rise building curtain wall, basic employing loose mail dispersion is installed, existing installation method, speed of application is slow, and the precision controlling difficulty in installation process is big, after installation, the cumulative errors between curtain wall and steel construction are relatively big, and the installation of follow-up glass curtain wall is produced considerable influence.
Existing mounting technique and technique:
Firstly the need of the installation completing relevant position steel structure member, after Steel Structure Installation completes, just can carry out the associated construction of curtain wall steel framework.
Steel construction curtain wall base of frame needs to arrange embedded part on 60 layers of concrete floor, it is necessary to synchronously complete when constructing with floor steel bar template. Loose mail is installed subsequently, first installs its column, after two root post installations, then by middle contact cross bar installation.
Subsequently by same order successively upwards loose mail installation. This installation method is higher for installing positioning accuracy request, and long construction period, and speed of application is slow, is easily generated bigger planar dimension deviation. Owing to this engineering cladding glass is installed on the inclined-plane of steel frame, the rectangle plane dimensional requirement therefore two root posts and cross bar formed is higher, and deviation is slightly larger will result in the result that glass curtain wall cannot be installed. If its rectangle plane angle of inclination deviation is relatively big, also will result in the discount on whole structure.
Therefore, how to provide that a kind of installation accuracy is high, efficiency is high and can ensure that the curtain wall main frame that glass curtain wall is installed smoothly becomes Pin installation method, it has also become construction circle needs the technical problem of further improvement and optimization.
Summary of the invention
It is an object of the invention to provide a kind of curtain wall main frame and become Pin installation method, adopt patch unit structure that second section and curtain wall steel framework above are installed successively from the bottom to top in the way of lamellar installation, may insure that between the adjacent crossbars that glass curtain wall is installed on smoothly described patch unit structure place perpendicular, be effectively increased installation effectiveness and precision.
For solving above-mentioned technical problem, the present invention provides following technical scheme:
A kind of curtain wall main frame becomes Pin installation method, comprises the steps:
1st step, required floor structure is arranged to install the embedded part of first segment curtain wall steel framework, prefabrication is for forming the patch unit structure of second section and curtain wall steel framework above, described patch unit structure includes two root posts and connects a cross bar of described two root posts, described column is hollow pipe, the sleeve that the bottom of every root post internal portion respectively exposes, the inner surface of the outer surface of described sleeve and described column matches, and between the described sleeve in described patch unit structure, by positioning, angle steel is fixing to be connected;
2nd step, installs first segment curtain wall steel framework in the way of loose mail installation, first installs the column of described first segment curtain wall steel framework, then arrange cross bar between the column of adjacent described first segment curtain wall steel framework;
3rd step, installs second section and curtain wall steel framework above from the bottom to top successively, thus completing the installation of whole curtain wall steel framework in the way of lamellar installation.
Optionally, becoming in Pin installation method at above-mentioned curtain wall main frame, the mode that described lamellar is installed comprises the steps:
31st step, saves the patch unit structure hoisting needed for curtain wall steel framework to installation site by installing next, cuts off the location angle steel of patch unit structural base, be sheathed on by sleeve on the corresponding column of bottom installation;
32nd step, proceeds the 31st step, until completing the installation of the patch unit structure of the curtain wall steel framework of all joints;
33rd step, installing the Inter cross bar of second section and adjacent lamellar cellular construction above, completing thus completing the installation of whole curtain wall steel framework.
Optionally, becoming in Pin installation method at above-mentioned curtain wall main frame, described 32nd step follows Construction of Steel Structure progress, the curtain wall steel framework that successively upwards construction saves accordingly.
Optionally, become in Pin installation method at above-mentioned curtain wall main frame, by welding manner, sleeve is sheathed on the corresponding column of bottom installation.
