Embodiment Construction
[0026] It should be noted that the orientation words "up and down" in this embodiment are all described according to the drawings, and do not constitute a limitation to the present invention.
[0027] Attached below Figure 1-5 The present invention is described in further detail: as Figure 1-3 As shown, a prefabricated convex beam with limited deconstruction is placed on the column 3. The convex beam includes a lower unit rectangular member 2 and an upper unit rectangular member 1; the lower unit rectangular member 2 is a pre-tensioned prestressed structure composed of high-strength The prestressed steel bars 20, ultra-high performance concrete 21 and stirrups 22 are prefabricated, the prestressed steel bars 20 extend along the length direction of the lower unit rectangular member 2, the stirrups 22 extend along the width direction and height direction of the lower unit rectangular member, and the height direction The stirrup is located in the middle of the lower unit recta...

The invention relates to a beam and an application method thereof, in particular to a precast structural beam and an application method thereof, and belongs to the field of building structures. A finitely deconstructed precast convex beam is arranged on a column, and the convex beam comprises a lower unit component and an upper unit component; the lower unit component is of a pretensioned prestressed structure and is formed by precasting prestressed reinforcement and concrete, and a stirrup is arranged in the axial direction of the lower unit component, and the end of the stirrup extends out of the upper end face of the lower unit component and serves as one part of the upper unit component; the upper unit component is of a rear cast-in-place structure and is composed of reinforcement, a stirrup and concrete, and the reinforcement and the stirrup are arranged according to the design requirements; the size of the upper unit component is smaller than that of the lower unit component. Thebeam has the following advantages that the overall rigidity of the building structure space is improved; the stiffness of the components is enhanced, and the technical limitation of the height span ratio of ordinary reinforced concrete beams is broken; the gap between the plate thickness and the beam height is reduced, and the plate thickness and the beam height tend to be consistent; the space layout is more flexible.
Description
technical field [0001] The invention relates to a beam and an application method thereof, in particular to a prefabricated structural beam and an application method thereof, belonging to the field of building structures. Background technique [0002] The construction period of cast-in-place beams is long, and the quality of finished construction products is affected by factors such as the technical level of personnel and weather. In the traditional beamless structure, the columns often directly bear the load on the slab and the slab, which may easily cause the punching damage of the column to the slab. In common building structures, the beam height is much greater than the plate thickness, so in general, obvious beam structures can be seen in buildings. During the use of the building, for the sake of overall beauty and comfortable use, the spatial layout is generally considered based on the beams, resulting in inflexible spatial layout.
