Description

One-way superimposed sheet board side piece structure Technical Field The utility model belongs to the technical field of side joint of laminated plates, and particularly relates to a one-way laminated plate side joint structure. Background The traditional cast-in-situ construction has the problems of resource waste, serious pollution and the like, and prevents the industrialized transformation of the building. China puts forward the development goal of the assembled building, and the assembled ratio in the newly built building is required to be more than 30%. The reinforced truss concrete superimposed sheet (60 mm thick bottom plate) is an assembly type component which is widely applied at present due to good mechanical property, portability in construction, low cost, good quality, energy conservation and environmental protection. The laminated slab is the same as the cast-in-situ slab and can be divided into a unidirectional laminated slab and a bidirectional laminated slab. The unidirectional laminated slab is single in stress direction, so that during production, only stressed steel bars extend normally, distributed steel bars do not extend, the production efficiency is high, and the transportation and installation difficulty is relatively low. "Fourth generation homes" introduce large area air gardens and open terraces. To meet the requirements associated with fabricated structures, floorslabs in the air garden and open deck areas also require the use of fabricated components. When the unidirectional laminated plates are adopted, the unidirectional laminated plates are often closely spliced in order to give full play to the advantages of assembly, namely the unidirectional laminated plates are tightly attached to each other on the plate side, the unidirectional laminated plates are connected by arranging the splice connecting reinforcing bars on the bottom plate of the unidirectional laminated plates, and the unidirectional laminated plates are not connected by arranging a section of post-cast strip. Therefore, the side seam of the unidirectional laminated slab can have the problem of water leakage. The large-area areas such as the air gardens and the open terraces have a large number of plate side seams, and once leakage occurs, the use functions and living experience of the building are seriously affected. Therefore, there is a need to develop a one-way laminated slab side seam construction to solve the above-mentioned problems. Disclosure of utility model Aiming at the technical problems in the prior art, the utility model provides a one-way laminated slab side seam structure for solving the problem of leakage of the one-way laminated slab side seam. The technical scheme for solving the technical problems is as follows: a one-way laminated slab side joint structure comprises, from bottom to top: Each bottom plate comprises a steel bar truss, wherein the steel bar trusses comprise upper chord steel bars, lower chord steel bars and web member steel bars, and the upper parts of the steel bar trusses extend out of the bottom plates; The joint connection steel bars continuously penetrate through the joint joints of all the adjacent bottom plates in the direction perpendicular to the steel bar truss, the length direction of the joint connection steel bars covers the transverse full width of the spliced adjacent bottom plates, and the two ends of the joint connection steel bars extend to the outer edges of the outermost bottom plates; The additional through length constructional steel bars are arranged in parallel to the direction of the steel bar truss, are positioned on one side of the bottom plate close to the splicing seams, and are overlapped on the upper surfaces of the splicing seam connecting steel bars; Overlapping layer steel bars; The post-cast concrete composite layer is densely filled on the upper surface of the adjacent bottom plate and the splice seam, and the whole structure which is stressed cooperatively with the bottom plate is formed by coating the splice seam connecting steel bars, the additional through-length construction steel bars and the composite layer steel bars. On the basis of the technical scheme, the utility model can be improved as follows. Further, the thickness of the post-cast concrete laminated layer is more than or equal to 100mm.
