Connecting structure for joint of one-way laminated slabs and construction method
The invention relates to a connecting structure for a joint of one-way laminated slabs and a construction method. The connecting structure comprises an upper cast-in-place layer and a lower prefabricated layer, wherein the lower prefabricated layer comprises more than two prefabricated slabs, and the adjacent prefabricated slabs are spliced and connected; a joint exists in the splicing position of the adjacent prefabricated slabs, transverse steel bars and longitudinal steel bars are arranged in the upper cast-in-place layer in the joint position, the transverse steel bars are located over the joint and are perpendicular to the joint, and the longitudinal steel bars are parallel to the joint; and a square groove is formed in the bottom of the lower prefabricated layer, is located in the joint position and is arranged in the length direction of the prefabricated slabs in a full-length mode, and a reinforcing mesh is arranged in the square groove which is filled and flattened with cement mortar. According to the connecting structure, the interior of the upper cast-in-place layer in the joint position cannot crack due to stress, the condition that the appearance is influenced because the lower part of the joint position of the laminated slabs has non-stress cracks in the later use process can be avoided, additionally, the connecting structure is simple, the structural stress and structural requirements can be met, and factory prefabrication and site construction and installation can be convenient.
本发明涉及一种单向叠合板拼缝处连接构造和施工方法，包括上部现浇层和下部预制层，下部预制层包括两块以上预制板，相邻预制板之间拼接连接；在相邻预制板的拼接处存在拼缝，在拼缝位置的上部现浇层内包括横向钢筋和纵向钢筋，横向钢筋位于拼缝正上方并垂直于拼缝，纵向钢筋平行于拼缝；下部预制层底部设置方形槽，所述方形槽位于拼缝位置且沿预制板长度方向通长设置，方形槽内设置钢筋网片，并由水泥砂浆填实抹平。本发明既能保证拼缝位置上部现浇层内不会因为受力导致开裂，又能避免叠合板拼缝位置下部在后期使用过程中出现非受力裂缝，影响外观，同时该连接构造简单，既能满足结构受力构造要求，又能使工厂预制和现场施工安装方便。
