自保温混凝土砌块是应我国建筑节能的要求而研发的一种新型节能砌块。通过对这种新型自保温砌块砌体抗弯性能的测试,结果表明:自保温混凝土砌块砌体受弯破坏过程非常短暂,无论是沿通缝受弯还是沿齿缝受弯,破坏前均无明显征兆,属于脆性破坏;自保温混凝土砌块砌体沿通缝截面抗弯破坏的破坏形式均为沿灰缝处的破坏,沿齿缝截面抗弯破坏的破坏形式为沿中间灰缝和砌块的垂直破坏,两类受弯构件的破坏面都较为平整;自保温混凝土砌块砌体沿通缝截面的弯曲抗拉强度和沿齿缝截面的弯曲抗拉强度均大于普通混凝土砌块砌体的相应弯曲抗拉强度规范计算值。建议将此砌块在框架结构的填充墙施工中推广使用。
Self-insulation concrete block is a new energy-saving building block that should be developed according to the requirements of building energy efficiency in our country. The results show that the bending failure process of self-insulation concrete block masonry is very short, whether it is bending along the through seam or bending along the tooth seam, All have no obvious signs and they are brittle failure. The failure forms of bending damage along the through-seam section of the self-insulation concrete block masonry are all along the crack along the ash seam. The damage form along the bending fracture of the tooth section is along the middle mortar And the vertical failure of the blocks, the failure surfaces of the two types of flexural members are relatively flat. The flexural tensile strength and flexural tensile strength along the cross-section along the through-seam of the self-insulating concrete block masonry are both greater than that of ordinary concrete masonry Calculation of the corresponding bending tensile strength of block masonry. Proposed to promote the use of this block in the infill wall construction of the frame structure.
