Embodiment 1

[0042] Embodiment 1 is a prefabricated reinforced concrete slab member with grooves, such as figure 1 , figure 2 As shown, the longitudinal edge of the plate 11 is arranged with transverse grooves 12, which are arranged alternately with the protrusions 13; the plate 11 has several longitudinal holes 14, and the holes near the longitudinal edge intersect with the transverse grooves 12; the plate 11 is provided with mounting rings 15 . When prefabricated reinforced concrete slab members are used as walls, the length is generally taken as the height of the building, the width is generally taken as a modulus of 300, and the thickness is equal to the thickness of the wall.

[0043] The preparation method of embodiment 1 comprises the following steps:

[0044] 1) Arrange the flat bottom form 31, two side forms 32 and two top forms 33 on the production site according to the size of the prefabricated components, such as image 3 , arranging reinforcement cages and suspension rings...

Embodiment 2

[0050] Embodiment 2 is a prefabricated reinforced concrete T-shaped wall column member with grooves, such as Figure 8 As shown, the longitudinal edge of the T-shaped wall column member 81 is arranged with transverse grooves 82 (at least one longitudinal edge is arranged with transverse grooves), which are arranged alternately with the protrusions 83 on the longitudinal edges; the T-shaped wall column member 81 has several longitudinal holes 84, the hole near the longitudinal edge intersects with the transverse groove 82; the T-shaped wall column member 81 is provided with an installation ring 85. In practical application, the three limbs of the T-shaped wall column adopt the limb lengths that meet the requirements of the building structure. The length of the T-shaped wall column member is generally taken as the story height of the building, and the thickness is generally equal to that of the wall.

[0051] The preparation method of embodiment 2 comprises the following steps:...

Abstract

A precast reinforced concrete structure including a precast slab. The precast slab includes at least one longitudinal hole and a longitudinal edge. The longitudinal hole is parallel to the surface of the precast slab and is disposed in the vicinity of the longitudinal edge. The longitudinal edge includes a plurality of transverse recesses disposed at intervals, and the transversal recesses intersect with the longitudinal hole.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structural components, and in particular relates to a prefabricated reinforced concrete hollow component with transverse grooves on the longitudinal edge which is suitable for assembling integral structures and a manufacturing method thereof. Background technique [0002] During the construction of cast-in-place reinforced concrete structures, there are many on-site fabrications and wet operations, and there are a large number of intermediate links such as formwork projects and scaffolding projects, which waste resources and pollute the environment; the quality of employees and the environment of the construction site have a great impact on the construction quality, bringing Issues of building performance, quality and durability. To change the status quo of cast-in-place reinforced concrete structures, prefabricated concrete structures should be vigorously developed. The...
