Embodiment Construction
[0043] Such as Figure 1-Figure 15 As shown, the structure, production and assembly methods of the fully prefabricated one-way panel with splicing grooves of the present invention are as follows:
[0044] Such as Figure 1-Figure 2As shown, the formwork structure of the prefabricated concrete one-way slab 7, the four sides of the formwork structure are steel formwork 8, the steel formwork located on the longitudinal sides are respectively composed of upper and lower steel bars, and the negative moment bars 6 pass through vertically. Located between the upper and lower steel bars, there is a reserved hole 2 between the upper and lower steel bars, along the central axis of the negative moment bar 6, through which the fixed steel bars 19 are inserted into the fixed steel rings 20 to connect the upper and lower steel bars , form the steel templates on both sides of the longitudinal direction; the steel templates on both sides of the horizontal direction are respectively a steel b...

The invention relates to the field of prefabricated fabricated type concrete structure buildings, in particular to a structure of a fully prefabricated one-way plate with splicing grooves, a manufacturing method of the structure of the fully prefabricated one-way plate with the splicing grooves and an assembling method of the fully prefabricated one-way plates with the splicing grooves, the fullyprefabricated one-way plates with the splicing grooves and medium beams as well as the fully prefabricated one-way plates with the splicing grooves and edge beams. A prefabricated concrete one-way plate is formed by adopting a formwork structure, and the inner bottom of the prefabricated concrete one-way plate is perpendicularly provided with longitudinal steel bars and transverse steel bars; negative moment reinforcements are horizontally arranged and distributed on the upper portions of the two opposite sides of the prefabricated concrete one-way plate correspondingly, one end of each negative moment reinforcement extends into the prefabricated concrete one-way plate, and the other end of each negative moment reinforcement extends to the exterior of the prefabricated concrete one-way plate; and the splicing grooves are horizontally arranged and distributed in the upper portions of the other two opposite sides of the prefabricated concrete one-way plate correspondingly, and each splicing groove is a T-shaped groove. According to the structure of the fully prefabricated one-way plate with the splicing grooves and the manufacturing and assembling method of the structure of the fullyprefabricated one-way plate with the splicing grooves, on-site assembling is simpler, and the construction quality is easier to guarantee.
Description
technical field [0001] The invention relates to the field of prefabricated concrete structure buildings, in particular to a fully prefabricated one-way slab structure with splicing grooves, its production, fully prefabricated one-way slabs with splicing grooves and fully prefabricated one-way slabs with splicing grooves, fully prefabricated The method for assembling the one-way slab with splicing grooves and the center beam, and the fully prefabricated one-way slab with splicing grooves and the side beams. Background technique [0002] The prefabricated concrete structure has the advantages of fast construction speed, energy saving and environmental protection, and small amount of wet work on site. It has developed rapidly in China in recent years. The floor is an important component of the prefabricated concrete structure. At present, in the prefabricated concrete structure, the floor slabs used are generally laminated slabs, that is, semi-prefabricated and semi-cast-in-pl...
