Abstract
The utility model relates to an improvement of a reinforced concrete structural board, particularly a tensile reinforced concrete structural board with high strength. The utility model has the technical proposal that spring-shaped short steel wires are randomly incorporated into concrete aggregates during the casting process of the concrete structural board, and accordingly, the spring-shaped short steel wires are randomly arranged inside the structural board after the structural board is solidified. The structural board which is provided with the spring-shaped short steel wires can change the mechanics feature of concrete, and experimental results show that the percentage between the average tensile strength Rt and the pressive strength R of the structural board of the utility model is increased to 32 to 50 percent, and accordingly, the improved proposal enhances the tensile strength of the reinforced concrete structure effectively. The structural board of the utility model plays a very important role in raising engineering quality.
Description
The utility model relates to the improvement of reinforced concrete structure plate, especially a kind of high strength tension reinforcement xoncrete structure plate.
Tensile strength is one of concrete basic mechanical feature.And concrete tensile strength has only 8～12% of its compression strength, and compression strength is higher, and the percentage of tensile strength is lower.Therefore, seldom directly adopt concrete as the tension material.Known reinforced concrete structure plate is usually by using sand, cobblestone, concrete that cement and water are modulated into and framework of steel reinforcement are formed, the crack resistance of reinforced concrete structure plate, shearing, moment of torsion, shrinkage stress, concrete is all relevant with concrete tensile strength with the adhesion strength between framework of steel reinforcement.And the factor that influences concrete tensile strength is a lot, wherein holding between cement colloid and coarse-fine aggregate to assist power on the low side be main cause.This shows, improve concrete tensile strength, play crucial effect for the quality that improves the reinforced concrete structure plate.
The purpose of this utility model is the deficiency that exists at existing reinforced concrete structure plate, and a kind of high strength tension reinforcement xoncrete structure plate is provided.
High strength tension reinforcement xoncrete structure plate of the present utility model comprises concrete and framework of steel reinforcement that sand, cobblestone, cement and water are modulated into, it is characterized in that: the unordered short steel wire of spring shape that is mixed with in the aggregate.
High strength tension reinforcement xoncrete structure plate design science of the present utility model, rational in infrastructure, the short steel wire of spring shape that is distributed in the reinforced concrete structure plate can move the concrete mechanical characteristics of change.Experimental result shows, is provided with the average tensile strength Rt of reinforced concrete structure plate test specimen of the short steel wire of spring shape and the percentage of its compression strength R and rises to 32～50%, and the tensile strength of some test specimen is near its compression strength.This shows that the scheme of the reinforced concrete structure intralamellar part architecture advances that the utility model proposes has improved the tensile strength of reinforced concrete structure plate effectively.Adopt structural slab of the present utility model, will play crucial effect for improving construction quality.
The concrete structure of the utility model high strength tension reinforcement xoncrete structure plate is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of high strength tension reinforcement xoncrete structure plate.
Embodiment: can be clear that from Fig. 1, the profile of high strength tension reinforcement xoncrete structure plate and composition are basic identical with existing ordinary reinforced concrete structure plate, its composition comprises: water, sand 1, cobblestone 2, the concrete that cement 3 is modulated into and the framework of steel reinforcement 4 that sets within it, 5 on the short steel wire of spring shape are distributed in the sheet material internal structure in unordered mode.The short steel wire 5 of this spring shape is after being blended together with concrete orthopaedics is unordered, to cast on the framework of steel reinforcement 4, is fixed on sheet material inside after solidifying.
