AI Technical Summary

Benefits of technology

The new design uses an improved structure called a prestressed prefilled beam that includes a special part made from strong materials like steel or aluminum instead of traditional wooden columns used during building constructions. This makes it easier to construct buildings without sacrificial timber resources needed by older methods such as brick walls or cast iron frames. Additionally, this technology allows for better stability when installing diagonal bracings on top of existing structures while still providing strength against lateral loads caused by wind pressure. Overall, these technical improvements make up what's now commonly known as a type of lightweight material system (LSS).

Problems solved by technology

This technical problem addressed in this patented technology relates to improves the design for casting concrete foundations used in building constructions where there may have issues due to instability caused by excessive weight loads from supporting columns overlapping areas such as storage floors or basements.

Embodiment Construction

[0019] see Figure 1 to Figure 5. In the embodiment of a prestressed prefabricated beam with a laying head given in the present invention, it includes a beam body 1 and a prestressed steel strand 2 embedded in the beam body as the main reinforcement, and the beam body 1 is provided with stirrups 11 and the part of the stirrup 11 protrudes from the upper surface of the beam body, the end of the beam is provided with a shelving pick 3, and a trapezoidal gap 12 is provided under the pick 3, and a plurality of Formwork through hole 13. The shelving pick 3 transfers the floor load and construction live load to the main girder without temporary support at the end, which greatly facilitates construction. It is left in the beam after pouring to improve the integrity of the connection between the main beam and the secondary beam. Formwork support through hole 13 is used to set the shelving part of floor slab formwork support, so that the load of floor slab can be directly transmitted to

Abstract

The invention discloses a precast pre-stressed beam with shelving corbel outs. The precast pre-stressed beam comprises a beam body and a pre-stressed steel strand as a main reinforcement embedded in the beam body. The beam body is provided with stirrups stretching out of an upper surface of the beam body. The precast pre-stressed beam is characterized in that ends of the precast pre-stressed beam are provided with shelving corbel outs; trapezoidal notches are arranged below the shelving corbel outs; and the beam body is provided with multiple supporting formwork through-holes in a longitudinal direction. The precast pre-stressed beam provided with the invention adopts the shelving corbel outs so that construction is convenient; a cost is low; and integrity is good. The trapezoidal notches at the ends of the beam body have large gradient so that inclined stirrup arrangement after beam installation is convenient and beam end shearing strength is improved.
