摘要

采用烧结淤泥多孔砖复合保温材料,通过拉接浇筑形成结构保温一体化预制自保温墙体.研究了砌筑砂浆种类、砌筑方式、灌孔和插筋数量对烧结淤泥多孔砖砌体力学性能的影响.结果表明:对于烧结淤泥多孔砖砌体,薄层砌筑砂浆通缝抗剪强度标准值为0.52 MPa,比普通砂浆砌筑提高了 34%;标准砌筑方式比非标准砌筑方式的通缝抗剪强度提高了 15%;烧结多孔砖孔内铺设2根或者3根增强钢筋并灌浆后,砌体平均抗剪强度由0.53 MPa分别提高至1.39、2.25 MPa,分别提高了 162.26%和324.53%.3孔铺筋注浆试样的抗剪强度比2孔铺筋注浆试样的抗剪强度提高了 61.8%.

Abstract

A structural insulation integrated prefabricated self-insulated wall is formed by pulling and pouring sintered silt brick composite insulation material.This paper investigates the effects of masonry mortar types,masonry methods,number of grouting holes and reinforcing bars on the mechanical properties of sintered silt porous brick masonry.The results show that for sintered filt porous brick masonry,the standard value of shear strength for thin-layer masonry mortar through joints is 0.52 MPa,which is 34%higher than that of ordinary mortar masonry.The shear strength of the standard masonry method has increased by 15%compared to the non-standard masonry method.After laying 2 or 3 reinforcing steel bars in the holes of sintered porous bricks and grouting,the average shear strength of the masonry increased from 0.53 MPa to 1.39 MPa and 2.25 MPa,respectively,with an increase of 162.26%and 324.53%,respectively.The shear strength of the 3-hole reinforced grouting specimen increased by 61.8%compared to the 2-hole reinforced grouting specimen.
