Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, a reinforced concrete prefabricated slab is provided with longitudinal holes 2 parallel to the surface, the longitudinal edges of the prefabricated slab 1 are provided with transverse grooves 3 at intervals, and the prefabricated slab 1 is provided with transverse holes 4 parallel to the surface , the transverse hole 4 is arranged at the center of the transverse groove 3 , and the transverse hole 4 intersects the longitudinal hole 2 .
[0016] The transverse grooves 3 of the prefabricated panels 1 are alternately arranged on the two longitudinal edges, and two prefabricated panels 1 are fitted together through the transverse grooves 3 .
[0017] The prefabricated panels 1 can be combined into L-shaped, cross-shaped wall columns a...

The invention provides a reinforced concrete prefabricated slab. The reinforced concrete prefabricated slab is characterized in that longitudinal holes are formed in each prefabricated slab and are parallel to the surfaces of the prefabricated slab, transverse grooves are formed in the longitudinal edges of each prefabricated slab at intervals, transverse holes are formed in each prefabricated slab, are parallel to the surfaces of the prefabricated slab and are particularly formed in the centers of the corresponding transverse grooves, the transverse grooves in each prefabricated slab are formed in the two longitudinal edges of the prefabricated slab in a staggered manner, and every two corresponding prefabricated slabs can be embedded in each other via the corresponding transverse grooves. The reinforced concrete prefabricated slab has the advantages that seams of the reinforced concrete prefabricated slab can be conveniently and reliably connected with one another, accordingly, the reliability of connection between prefabricated members can be greatly improved, the reinforced concrete prefabricated slab is convenient to construct, high in production efficiency and quality and favorable for sustainable development, and resources can be saved.
Description
technical field [0001] The invention relates to the field of building decoration and decoration engineering, in particular to a reinforced concrete prefabricated slab. Background technique [0002] There are horizontal joints and vertical joints between prefabricated components in precast concrete structures, and the mechanical performance of joints determines the overall performance of the structure. The existing joint construction measures of precast concrete structures generally seek to achieve the same effect as cast-in-place concrete, but because the joint surface of new and old concrete at the joint is a weak link, it affects the mechanical performance and is easy to crack, affecting normal use. [0003] In order to reduce the weight of components, holes are generally arranged in prefabricated components to form prefabricated hollow panels. The connection between prefabricated hollow components is still a weak link in the existing technology. Contents of the inventi...
