precast prestressed concrete hollow lintel beam making machine

T-beam, used in construction, is a load-bearing structure of reinforced concrete, with a t-shaped cross section. The top of the t-shaped cross section serves as a flange or compression member in resisting compressive stresses. The web (vertical section) of the beam below the compression flange serves to resist shear stress and to provide greater separation for the coupled forces of bending.

SL(Shuangli) pre-stressed concrete lintel making machine could produce 4~6 pcs of pre-stressed concrete lintels at the same time, both time and labor could be saved.

Pre-stressed concrete lintel making machine works on the concrete platform, driven by the motor and transmitted through the speed reducer.The movement of the slipper block pushed the loose material to the forming container from the hopper.With the continuous working of the vibrate plate,the material condensed by pushing and discharging of air.press the concrete strong.The beams can be cut to different lengths from 4.2m-18m.Finished products with Strong load capacity ,smooth surface and good flatness.

Reinforced concrete T-beams

Concrete alone is brittle and thus overly subject to the shear stresses a T-beam faces where the web and flange meet. This is the reason that steel is combined with concrete in T-beams. A problem of shear stress can lead to failures of flanges detaching from webs when under load. This could prove catastrophic if allowed to occur in real life; hence, the very real need to mitigate that possibility with reinforcement for concrete T-beams. In such composite structures, many questions arise as to the particulars of the design, including what the ideal distribution of concrete and steel might be: “To evaluate an objective function, a ratio of steel to concrete costs is necessary”. This demonstrates that for all aspects of the design of composite T-beams, equations are made only if one has adequate information. Still, there are aspects of design that some may not even have considered, such as the possibility of using external fabric-based reinforcement, as described by Chajes et al., who say of their tested beams, “All the beams failed in shear and those with composite reinforcement displayed excellent bond characteristics. For the beams with external reinforcement, increases in ultimate strength of 60 to 150 percent were achieved”. When it comes to resistance to shear forces, external reinforcement is a valid option to consider. Thus, overall, the multiple important aspects of T-beam design impress themselves upon the student of engineering.
