Construction method for prestressed brick-concrete structure of rural self-built house
The invention relates to the technical field of building construction, in particular to a construction method for a prestressed brick-concrete structure of a rural self-built house. Comprising the following steps: constructing a foundation ground beam (embedding an anchorage device in the ground beam); constructing a main body structure; constructing a roof and a ring beam (embedding an anchorage device in the ring beam); connecting an upper anchorage device and a lower anchorage device by adopting a vertical steel strand; the left anchorage device and the right anchorage device are connected through a horizontal steel strand (hollow bricks are adopted in the vertical range of the steel strand and hollow bricks are adopted in the height position of the horizontal steel strand, and the steel strand is tensioned through a post-tensioning method); grouting is conducted in the hollow bricks; according to comparative analysis of field experimental data, by means of the construction method for the prestressed brick-concrete structure, the cracking load of the prestressed masonry is improved by about 20% compared with that of non-prestressed masonry; the anti-cracking bearing capacity is improved by about 50%; the displacement is increased by 40%-60% under an ultimate load; and the destroying form is obviously changed.
本发明涉及建筑施工技术领域，具体涉及一种农村自建房预应力砖混结构施工方法；包括以下步骤：基础地梁施工（地梁中埋设锚具）→砌筑主体结构→屋顶及圈梁施工（圈梁中埋设锚具）→上下锚具之间采用竖直钢绞线连接→墙柱四周及拐角设置构造柱，构造柱等间距预埋多个锚具→左右锚具之间采用水平钢绞线连接（钢绞线竖向范围内采用空心砖砌筑以及水平钢绞线高度位置采用空心砖砌筑→后张法张拉钢绞线）→空心砖内部灌浆；根据现场实验数据对比分析：采用本发明预应力砖混结构施工方法，预应力砌体开裂荷载比非预应力砌体提高20%左右；抗裂承载力提高50%左右；极限荷载时的位移增大40%~60%；破坏形态发生明显变化。
