当前建筑工程中,尤其是民用住宅工程普遍采用预制空心板作楼板和屋面板,方便了施工,缩短了工期。但是,由于预制板为块体安装,从而存在着一个施工中能否使相邻板侧表面与缝间砼粘结牢固,形成一个整体来共同抵抗和控制板的下挠变形的问题,这是防止天棚抹灰开裂的关键。为使板间灌缝砼能与板块形成整体,避免天棚 In current construction projects, especially civil residential projects, prefabricated hollow slabs are commonly used as floor slabs and roof slabs, which facilitate construction and shorten the construction period. However, since the prefabricated panels are installed as a block, there is a problem that whether or not the side surfaces of adjacent panels can be firmly bonded to the seams during construction can form a whole to jointly resist and control the down deflection of the panels. This is a problem. The key to preventing cracking in the plastering of the ceiling. In order to make the grouting between the plates and the plate to form a whole, avoid the ceiling
