The utility model discloses a preparation installation principle:
the utility model provides a novel crisscross column cold-formed thin wall type steel construction takes staggered arrangement with the non-bearing post of several rows, and bearing post on the bearing side is in order to be connected with the crossbeam and break off every layer and set up, and this all joints of not having not only avoided the non-bearing post are in same horizontal position, have kept the vertical continuity of non-bearing post again. The stressed member is formed by connecting small-section C-shaped steel and cold-formed thin-wall steel through bolts or self-tapping screws, the upper layer and the lower layer and the bottom layer are connected with the foundation through bolts, and the rest members are connected through self-tapping screws. The top cover is of a composite structure of cold-formed thin-wall section steel or a wood beam and an OSB directional plate, a sound insulation layer is arranged below the top cover and is sealed by a fireproof gypsum board, and fine stone concrete or mortar with the thickness of 20mm-50mm is additionally paved on the top cover.
For different bearing schemes, the mode of the non-bearing columns which are arranged in a staggered mode is different, because the horizontal bearing capacity in the bearing direction generally meets the requirement in experiments and calculation, so for the transverse bearing scheme, a plurality of rows of longitudinal non-bearing columns are arranged in a staggered mode to resist the horizontal bearing capacity generated due to earthquakes or other reasons; for the longitudinal bearing scheme, a plurality of layers of transverse non-bearing columns are arranged in a staggered mode to resist horizontal bearing force generated due to earthquake or other reasons; for the mixed bearing scheme, the mode of arranging the longitudinal and transverse bearing staggered columns is adopted to avoid the problem of limitation of the steel member factory processing size caused by overhigh layer number.
The utility model has the advantages that:
the utility model provides a novel crisscross column cold-formed thin wall type steel construction mainly uses in the high many high-rise light steel construction buildings of seismic fortification intensity. The utility model has the advantages of for crisscross column clod wash thin wall type steel construction can connect into a whole with the structure reliably to the problem of leading to structural failure because the produced horizontal bearing capacity of earthquake has been solved. Related components can be spliced, and the size problem of the section steel components in factory processing is effectively solved. The amount of light steel is also reduced.
