With Support Of Prestressed Composite Plate Mechanics Research

Prestressed composite plate with stents, with large bearing capacity, good stiffness, good seismic performance, and a series of superior characteristics, therefore, has been applied gradually in modern architecture and promotion. With state of the housing industrialization, the new type of composite in the actual engineering demand increasing, so meet the construction material of industrial production has become many experts in the field at thinking problem.This article through studies with stents precast prestressed concrete composite slab bottom of static load test, respectively in a single span opposite simply supported edges and two continuous simply-supported research under the condition of precast floor bearing capacity and deflection of the problem, and will test the data map into, observe its change rule under different load, this for later engineering application provides the theoretical guarantee.Considering the belt stent composite plate in the process of practical application, the original one-way slab composite rectangular plate or square plate, due to the effect of after pouring concrete, or by after composite plate is one-way slab stress of the bearing condition. To use for composite plate joining together into two spell, three spells, four, five or composite plate plate for stress analysis of simulation.Results showed that the precast floor when the deflection of 10/100, change the stress of the plate is still in the elastic scope, its load is also fully meet the requirements of construction live load board face, two cases of bearing capacity of continuous simply-supported. So the precast slab can be used in construction as a permanent template. In ABAQUS software to simulate composite plate joining together into two spell, three spells, four, five or composite plate plate stress nephogram, can see from the chart, on the edges simply supported cases, composite plate is still in accordance with the one-way slab after stress.Finally summarizes and puts forward the experiment and reasonable Suggestions for improvement and still need to solve the problem, to bring support the improvement of the technical specification for prestressed concrete composite plate structure provides theory basis, for it can relatively widely used in large span construction construction to provide reliable technical support and theoretical support.
