Precast beam with multi-ribbed plate shelving notches
The invention discloses a precast beam with multi-ribbed plate shelving notches. The precast beam comprises a concrete beam body, main ribs and stirrups, a plurality of shelving notches are formed inthe upper portion of at least one side of the concrete beam body in the longitudinal direction, the distance between the shelving notches ranges from 300 mm to 600 mm, the shelving notches are small in the lower portions and large in the upper portions and are in an inverted trapezoid shape, the main ribs are common steel bars or prestressed steel strands and are buried in the lower portion of thebeam body, the stirrups comprise shear-resistant stirrups and structural stirrups, the structural stirrups are buried in the beam body at the lower portions of the shelving notches, the shear-resistant stirrups are arranged in the beam body along the inner sides of the shelving notches, and the shear-resistant stirrups are exposed to a certain height towards the upper surface of the beam body along the inner sides of the shelving notches. According to the precast beam, correspondingly-placed multi-ribbed plates can be designed into continuous plates, the integrality is good, the shelving notches are formed in a one-time pouring mode through shaping dies, and the construction quality is good.
一种带有密肋板搁置缺口的预制梁，包括砼梁体、主筋和箍筋，所述砼梁体至少一侧上部沿纵向设有多个搁置缺口，所述搁置缺口间距为300mm～600mm，所述搁置缺口下小上大呈倒梯形，所述主筋为普通钢筋或预应力钢绞线，所述主筋埋设于所述梁体下部，所述箍筋包括抗剪箍筋和构造箍筋，所述构造箍筋埋设于所述搁置缺口下部的梁体内，所述抗剪箍筋在所述梁内沿所述搁置缺口内侧布置，所述抗剪箍筋沿所述搁置缺口内侧向所述梁体上表面露出一定高度。该预制梁可将对应搁置的密肋板设计成连续板，整体性好，且搁置缺口采用定型模具一次性浇筑成型，施工质量好。
