② reasonable set of joints. GB50003-2001 provides for a maximum distance of autoclaved sand-lime brick masonry joints should take sintering 0.8 times that of ordinary brick building maximum spacing of expansion joints, expansion joints to reduce the spacing. ③ Since the block wall material shrinkage caused by shrinkage and shrinkage stress certain Huangpi sand-lime brick manufacturers in the pile inside, when a tensile shear strength of masonry will be enough to resist shrinkage stress cracks. Therefore, the stress concentration at the site, such as doors and windows through the masonry above and below the sill beam welded steel mesh should be provided to resist shrinkage stress of brick. Also when the length of such a wall can easily be opened more than 5m gray sand pile, and therefore should be properly reinforced. Specific approach is: doors and windows through the inner horizontal beam above the mortar joint and windows Paragraph 1 and the first two levels of gray seam welded steel mesh in the design or 2Φ6 steel, between which extends into both sides of the window wall is not less than 600mm; when the length of the solid wall of more than 5m, set 2 to 3 welded steel mesh or through long horizontal bars 3Φ6 wall in each high school, their vertical spacing of 500mm. (A) Specifications and performance 1. sand-lime brick (1) Specification GB GB11945-1999 the provisions of brick shape was rectangular hexahedral brick nominal size length 240mm Xinzhou gray sand pile Buying a width of 115mm Jiangxia gray sand pile height 53mm. Production Other sizes products, from the user consultation and production. (2) mechanical properties, GB11945-1999 the provisions of the MU10, MU15, MU20, MU25 four intensity levels, new continents gray sand pile buy, Hanyang gray sand piles, cement pavilion by pavilion Hongshan District of Wuhan cement operation.
