Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1, the embodiment provides a beam-wall separation prefabricated structure, which includes a prefabricated infill wall 3 and prefabricated frame beams 2 provided on an upper end surface of the prefabricated infill wall 3.
In the embodiment, the two sides of the prefabricated frame beam 2 are provided with laminated floor layers, and the floor layers on the two sides comprise a laminated floor prefabricated layer 10 at the bottom and a laminated floor cast-in-place layer 1 arranged above; the upper end of the composite floor cast-in-situ layer 1 is connected with the wall surface on the upper part through a concrete sand rack 11, and the upper part of the prefabricated frame beam 2 is poured in the composite floor cast-in-situ layer so as to form an integrated connecting structure with the composite floor layer.
The prefabricated frame beam 2 comprises a frame beam main body with a rectangular cross section, and beam built-in ribs are arranged in the frame beam main body, in the embodiment, the beam built-in ribs comprise four transverse ribs extending in the length direction and longitudinal ribs bound around the transverse ribs, the four transverse ribs all extend out of two ends of the frame beam main body of the prefabricated frame beam 2 in the length direction, and two ending ends of the longitudinal ribs extend out of the upper side face of the frame beam main body and are turned over to form a barb structure; as can be seen from fig. 1, the barb structure of the longitudinal rib is poured into the cast-in-place layer 1 of the composite floor slab, and similarly, the transverse ribs are all extended and anchored into the cast-in-place columns or the shear walls on the two sides in the length direction for fixation, so that the prefabricated frame beam 2 is firmly connected with the main body.
Meanwhile, shear keys (not visible in the figure) are also preset at two ends of the frame beam main body in the length direction to assist transverse ribs, increase the contact surface of the prefabricated frame beam 2 and cast-in-place concrete and improve the shear resistance of the prefabricated frame beam; preferably, the four transverse ribs are arranged at four vertex angles of the prefabricated frame beam 2, and the shear keys are arranged in the middle along the thickness of the beam, so that optimal shear balance is realized.
The prefabricated frame beam 2 is arranged on the upper side of the prefabricated filler wall 3 and is connected with the prefabricated filler wall 3 through a mortar layer 21 by a mortar setting process; in the embodiment, in order to ensure the stability and the connection strength of the seat grout layer 21, the upper end surface of the prefabricated filler wall 3 is trapezoidal, so that the two ends of the seat grout layer 21 are thickened, and the stability is better.
In order to ensure the wall strength and the side connection strength of the prefabricated filler wall 3, two ends of the prefabricated filler wall 3 in the length direction are reserved with built-in sleeves (not visible in the figure); the prefabricated infilled wall 3 is internally provided with wall built-in ribs connected with the sleeve in a threaded manner, and in the installation process, the reserved sleeve threaded reinforcing steel bars are connected with cast-in-place components on two sides, so that the requirement on connection strength is met.
