How long is the dry pillar of the wall?
The structural stability of the primary and secondary frames (ie columns and beams) should be consistent with the design requirements. Taking into account the ease of construction, the column should be arranged with the vertical arrangement of stone with the layout of the beam should be arranged with the layout of the horizontal joints of stone match. Column and structure of the connection: the wall structure every 2 meters with embedded iron, the column and the embedded iron through the short (10 channel) welding, column construction taking into account the impact of temperature stress, every 6 meters off Open, the middle of 15mm gap. Note that the disconnect is at the junction of the crossbar. The connection of the beam to the column shall also take into account the effect of the temperature stress, which is connected by means of a corner code, a bolt and a column. Columns and beams and structural planes According to the size of the keel, the construction of the general are generally retained 30 to 50mm spacing, which is conducive to the installation of column beams, but also conducive to the elimination of construction (structural planes, columns and beams) error, Channel steel, beam angle steel should meet the design requirements.
According to the seismic requirements, the connection with the main body using Q235 low carbon steel, its chemical composition, mechanical properties, including yield points should meet the "GB700 a 88" national standards, all the remaining pendant are made of stainless steel (stainless steel 0Cr18Ni9) processing Made, and according to "GB4237 a 92" standard test of stainless steel chemical composition and strength limit, elongation and other physical properties, pendant should be bearing shear and deflection test. Electrode using E4303 carbon steel electrode, welding rod should be consistent with "GB5117 a 85" national standards.
This is not necessarily, usually do dry hanging stone people think that the spacing is 1.2 meters. In fact, this is calculated by the general construction drawings are marked, there is no words to see the structure design calculation book.
Dry hanging stone curtain wall itself strength, involving the thickness of the stone length and width of the size of the fixed side with dry hanging. According to the metal and stone curtain wall engineering technical specifications (JGJl33-2001) requirements: stone wall for the stone thickness should not be less than 25mm, stone area should not be greater than 1.5m2, pendant generally use stainless steel pendant. Angle steel fittings, stainless steel pendant, bolts, electrodes, structural adhesive should be proof of material, factory certificate and inspection report.
