Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a post-cast zone dirty isolation board. Background Art

[0002] Post-cast strips are concrete strips set aside at the corresponding positions of the foundation slab, wall, and beam in accordance with design or construction specifications to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven shrinkage or settlement. Post-cast strips temporarily divide the structure into several parts. After the internal shrinkage of the components, the concrete for the construction is poured again after a period of time to connect the structure into a whole. The pouring time of the post-cast strip should be selected when the temperature is relatively low. Cement or concrete with a small amount of aluminum powder added to cement can be poured. Its strength grade should be one level higher than the strength of the component to prevent cracks between the new and old concrete and form weak parts. The location of the post-cast strip should also consider different consumption factors of formwork and other measures. During the pouring of post-cast strip concrete, isolation mesh is needed to connect the concrete.

[0003] At present, there are certain difficulties and complexities in the construction of post-cast strips of basement floor slabs, and certain requirements need to be met in terms of construction conditions and time. If the construction time is too short or the construction conditions are not sufficient, the appearance quality of the post-cast strips of the basement floor slabs will be reduced. In addition, in the post-cast strips of the basement floor slabs, if the isolation boards used do not meet the construction requirements, or the quality of the isolation boards is poor during construction, defects will occur in the appearance quality of the post-cast strips of the basement floor slabs. Therefore, a dirty isolation board for the post-cast strips is needed to improve the above problems. Utility Model Content
