The invention relates to the field of prefabricated concrete structure buildings, in particular to an improved hidden beam type connection full-prefabricated slab structure and a manufacturing and assembling method thereof. Transverse stress ribs and longitudinal stress ribs are horizontally distributed in a full-prefabricated slab in a crossed mode, the two ends of the transverse stress ribs andthe longitudinal stress ribs are bent into the structures at the inner side of the full-prefabricated slab, and vertical sections between the bottom edges and the bent sections of the longitudinal stress ribs and the transverse stress ribs are exposed out of the full-prefabricated slab; the exposed portions of the longitudinal stress ribs at the corresponding positions of the two full-prefabricated slabs are in tight staggered overlapping to form a closed hoop, angle iron with a hook penetrates through the closed hoop and is hooked to the closed hoop through the hook, and the angle iron and the closed hoop are bound; expanded concrete is poured at the joint of the two full-prefabricated slabs, and connection between the two full-prefabricated slabs is completed. Compared with an assembledconcrete composite floor slabs and cast-in-place concrete floor slabs, the wet operation amount is greatly lowered, on-site splicing is easier, the construction quality is more easily ensured, and thestructure is applicable to the large slab span.

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.

The invention discloses a T-shaped rigid seam coupled wall with a pre-embedded seam beam segment, and a construction method thereof. The coupled wall comprises a first wall unit and a second wall unit which are mutually vertically connected and form a T shape, wherein the first wall unit and the second wall unit are both prefabricated members and the two are connected through a seam post-cast strip. The node connection is safe and reliable, the antivibration performance is good, and at the same time, factory fabrication and onsite installation are also carried out simultaneously; and wall assembling units are prefabricated in a factory, splicing installation is performed in a field, structural members are manufactured and installed at the same time, the construction speed of a main body structure is improved, it is guaranteed that a construction project is completed on schedule, in a construction process, through structural assembling and combination, the wet construction amount of a concrete field is reduced, the application quantities of templates and temporary supports are reduced, building garbage is reduced, the requirements for saving materials and protecting environment are realized, and the purpose of green construction is ahiceved.
