Reverse rib laminated floor slab and construction method thereof

Abstract

The invention relates to the field of assembling an integrated building structure, in particular to a reserve rib laminated floor slab and a construction method thereof. The reserve rib laminated floor slab comprises a plurality of prefabricated reserve rib plates assembled together; a sunken groove is formed in the upper surface of each prefabricated reserve rib plate; and a later pouring concrete layer is arranged above the plurality of spliced prefabricated reserve rib plates. The construction method of the reserve rib laminated floor slab comprises the following steps of S1, making the prefabricated reserve rib plates; S2, mounting supports on a main beam and a sub beam; S3, hoisting the plurality of prefabricated reserve rib plates with the groove surfaces upwards, horizontally layingthe plurality of prefabricated reserve rib plates on the main beam or the sub beam in sequence, and splicing the plurality of prefabricated reserve rib plates to form a floor slab; and S4, pouring aconcrete layer to form the laminated floor slab. According to the reserve rib laminated floor slab and the construction method thereof, through adoption of the structure, the reserve rib laminated floor slab can be used as a cast-in-place concrete template so that the template usage and the support usage can be reduced, the construction efficiency can be effectively enhanced, and the cost can be saved. The reserve rib laminated floor slab has the advantages of smoother lower surface of the floor slab and more beautiful building effect.

Description

Technical field [0001] The invention relates to the field of prefabricated and assembled integral building structures, in particular to an anti-rib laminated floor slab and a construction method thereof. Background technique [0002] Precast concrete structures have the advantages of saving materials, accelerating construction progress, improving the quality of components, and energy saving and environmental protection. Precast concrete structures have broad development prospects. [0003] At present, as a floor structure that can be used to assemble monolithic buildings, laminated slabs have the following shortcomings during the construction process and have not been widely used: (1) A large number of floor templates still need to be laid; (2) Current prefabrication The span of the laminated floor is not large enough; (3) The prefabricated slab body and the post-poured concrete lack a stable connection; (4) The protruding ribs can be seen at the bottom of the slab, which affects t...
