Masonry body and cut force wall Zhijian of gap with mortar fill, and squeeze real, gray sewing cross flat vertical, level gray sewing should be control in 15mm around, but not is less than 10MM, not is greater than 20mm, level gray sewing of full degrees shall not below 80%, vertical to gray sewing should be control in 20mm around, but not is less than 15mm, not is greater than 25mm, vertical sewing shall not appeared transparent sewing. Infilled beams according to the building plans of opening hole in lintel Universal Atlas use. Load levels, the design requirements, when the hole close to the shear walls, beams using in-situ construction, concrete shear walls, according to relevant standard specification for anchorage. By design requirements set structure column, ,4、一块长方体花岗岩纪念碑高、宽、厚分 33别为10m、3m、2m，密度为2.5×10kg/m。 5地面所能承受的最大压强为1.2×10Pa，为使地面能承受纪念碑，现把纪念碑立在高1m、 33 密度为2×10kg/m的长方体基石上。(g取10N/kg) (1) 纪念碑的质量是多少, (2)若纪念碑直接矗立在地面上，它对地面的压强多大, (3)基石的底面积至少要多大, 15.A、B立方体，A边长Pu ash must not exceed 1500mm. Block in place and more are: block, should be watered before rushing to dust, clear blocks debris on the surface of the rear handle. During handling and transport of aerated concrete blocks, throws and dumping is strictly prohibited, after entering varieties and specifications, respectively a tidy, stacking height should not be more than 2m. Aerated concrete blocks to prevent rain. When each layer of masonry, from the corner or anchor blocks, starting at the crane masonry skin, correct skin, Pi Pila control elevation of masonry and wall flatness.
