Background technique

At present, when pouring the top ring beam of hollow block masonry, in order to prevent the concrete of the ring beam of the hollow block masonry wall from flowing into the adjacent masonry of the ring beam, two methods are often used: pre-pouring a part of concrete on the top skin block or laying dense mesh steel mesh. method. Pre-pouring concrete in the roof blocks is a complicated process and inconvenient to construct. Laying dense mesh steel mesh can easily cause concrete to leak into the cavity of the lower block when the ring beam is poured, resulting in material waste.

According to the relevant specifications of masonry, U-shaped blocks can be used as templates for cast-in-cast ring beams in non-seismic areas, which can solve the shortcomings of the above two methods of construction. However, in earthquake-resistant areas due to the ring beams of block masonry The bond with the lower masonry blocks is weak, so U-shaped blocks are not allowed to be used as formwork for masonry blocks.

Therefore, in view of the shortcomings of using the above U-shaped block as a ring beam formwork, it is necessary to improve the design of the U-shaped block, which can not only be used as a ring beam pouring formwork, but also form a good overall effect with the lower masonry.
