Background
At present, with the advance of national policies on the assembly type building industry, the application of the assembly type composite slab is more and more extensive, the ribbed prestressed concrete composite slab has the advantages of large rigidity, no support and the like and is widely applied, but some problems also occur in the application process, for example, the arching values between adjacent plates are different due to the adoption of prestress, the arching values are difficult to control in production, and the popularization and the application of the ribbed prestressed concrete composite slab in houses and buildings with higher requirements on the flatness of the plate bottom can be influenced.
At present, the method for adjusting the arching value of the prestressed ribbed concrete composite slab during construction mainly comprises the following two methods: firstly, exert external load for prestressed concrete superimposed sheet through hydraulic loading, reaction frame device, control adjacent superimposed sheet's anti-arch value for same numerical value through external load, remove hydraulic means, reaction frame device again after having pour superimposed sheet concrete. Although the hydraulic and reaction frame device has good construction effect and high automation degree, the volume and the weight of the hydraulic and reaction frame device are large, the load borne by the laminated slab in the construction stage can be increased, and the safety of the laminated slab in the construction stage is not good; secondly, the reaction frame device is slow in installation speed, occupies construction space and influences construction efficiency.
Secondly, V-shaped grooves are formed in two ends of a bottom plate during production of the partial prestressed concrete composite slab, V-shaped seams between the plates are sealed by mortar and other materials during construction, and the flatness between the plates is controlled by the method; the end part of the laminated slab is made into a V-shaped groove, so that the production efficiency of the laminated slab can be reduced, a production mold is complex, the construction speed is reduced by secondary plugging of plate seams in the construction stage, the quality of the plate seam plugging is difficult to control, and the risk of cracking still exists; secondly, for different laminated slabs, due to the fact that the arch camber values are different due to factors such as materials, tensioning prestress and production time, the flatness between the slabs cannot be controlled.
