摘要
对轻质烧结页岩砖砌体螺栓锚固进行试验,选用4种常用规格螺栓,根据砖体孔形特点及施工随机性,选取4个特定锚固位置进行。试验结果证明,螺栓直径增加,极限抗拉力也相应增加;锚固位置不同,极限抗拉力也不同。建议在后续试验和施工中采用直径10mm型号的螺栓,以满足安全使用要求。
Bolts of 4 routine specifications are selected for bolt anchorage test of light-weight sintered shale brick masonry and four certain anchorage positions are tested according to brick hole shape and construction randomness. The test result proves that limit tensile strength will be increased after increase of bolt diameter and varies at different anchorage positions. It is suggested that bolt whose diameter is 10mm shall be adopted during subsequent test and construction to satisfy safety requirements.
