Background
At present, when casting a ring beam at the top of a hollow block masonry, two methods of pre-casting a part of concrete on a top skin block and paving a dense-mesh steel wire net sheet are adopted to prevent the ring beam concrete of a wall of the hollow block masonry from flowing into adjacent masonry of the ring beam. Concrete is precast in the top skin building block, the working procedure is complex, and the construction is inconvenient. The laying of the dense mesh steel wire meshes easily causes that concrete leaks into the cavity of the lower building block when the ring beam is poured, and material waste is caused.
According to the relevant standards of the masonry, the U-shaped blocks can be used as templates of cast-in-situ ring beams of the masonry blocks in a non-anti-seismic area, so that the defects existing in the construction of the two methods can be overcome, but the ring beams of the masonry blocks are combined with lower masonry blocks weakly in the anti-seismic area, so that the U-shaped blocks are not allowed to be used as templates of the masonry blocks.
Therefore, aiming at the defects of the U-shaped block used as the ring beam template, the U-shaped block needs to be improved and designed, and can be used as the ring beam pouring template and form good integral action with the lower masonry.
