Overlapped plate with enhanced bidirectional force transfer performance

Abstract

The invention discloses an overlapped plate with enhanced bidirectional force transfer performance, and belongs to building section bars. The overlapped plate structurally comprises a prefabricated bottom plate, at least one reinforcing steel bar truss, at least two anti-pulling connectors and bidirectional configuration reinforcing steel bars. One end of each reinforcing steel bar truss and one end of each anti-pulling connector are respectively positioned in the prefabricated bottom plate, the bidirectional configuration reinforcing steel bars are positioned on the lower portions of the anti-pulling connectors and are arranged in the prefabricated bottom plate, the reinforcing steel bar trusses and the anti-pulling connectors are respectively positioned on two sides of the prefabricated bottom plate and are vertically arranged, each reinforcing steel bar truss is positioned between the two corresponding anti-pulling connectors, and the reinforcing steel bar trusses and the anti-pulling connectors are respectively arranged along the length direction of the prefabricated bottom plate. The overlapped plate has the advantages that tripping damage to new and old concrete joint surfaces at butted seams can be effectively prevented, and integral overlapped and spliced floor slabs are assuredly provided with excellent bidirectional force transfer mechanisms; the floor slabs are built in direct butted seam splicing modes during site construction, cast-in-situ zones with certain widths can be omitted, accordingly, the overlapped plate is high in construction speed, and the like.

Description

technical field [0001] The invention relates to a building profile, in particular to a laminated plate with enhanced two-way force transmission performance. Background technique [0002] Laminated slabs are an important component of prefabricated concrete structures and have been widely used. Due to limitations in production, transportation and hoisting, during the construction process, the floor of a single room is often assembled from multiple laminated panels. The joints between the sides of the laminated slabs require different construction methods due to different design principles. [0003] At present, in order to ensure that the assembled floor forms a two-way force transmission mechanism for the existing various types of laminated slabs, it is necessary to adopt the assembly method of setting cast-in-place belts at the joints, which leads to the addition of supporting formwork, scaffolding and lashing in the on-site construction. Multiple construction procedures su...

Problems solved by technology

However, the experimental research shows that when the vertical load of the slab in the direction of the vertical joint reaches about 20% of the ultimate load, the joint surface of the prefabricated and cast-in-place concrete at the joint will be disengaged, and the damage will be greatly affected. Reduce the bending stiffness of the directional strip, resulting in the inability of the overall laminated slab to form a good two-way force transmission mechanism
