Embodiment Construction

[0030] The connection method of the prefabricated reinforced concrete slab of the present invention will be described in detail below with reference to the drawings and embodiments.

[0031] A kind of embodiment of the connection method of the prefabricated reinforced concrete slab that the present invention proposes, as figure 1 , the side of the first prefabricated reinforced concrete slab 1 is pre-embedded with fully anchored and semi-circular steel bars 3 with exposed parts; the side of the second prefabricated reinforced concrete slab 2 is pre-embedded with fully anchored and semi-circular steel bars with exposed parts, The semi-annular steel bar is hung with a horizontal steel bar 4 whose end is bent upward. The horizontal steel bar can move and rotate on the semi-annular steel bar, and the position can be adjusted freely, which is convenient for the transportation and hoisting of the prefabricated reinforced concrete slab, and facilitates the positioning of the horizonta...

Abstract

The invention discloses a connection method of precast reinforced concrete slabs, and belongs to the technical field of building structures. The connection method comprises the following steps: first precast reinforced concrete slabs and second precast reinforced concrete slabs are connected as a whole, half annular reinforcing steel bars are embedded on lateral sides of the first precast reinforced concrete slabs, the half annular reinforcing steel bars are embedded on the lateral sides of the second precast reinforced concrete slabs, transverse reinforcing steel bars of which end parts are upwards bent are hung on the half annular reinforcing steel bars, the transverse reinforcing steel bars rotate around the half annular reinforcing steel bars, and end bent parts are inserted into a gap between the lateral sides of the first precast reinforced concrete slabs and the half annular reinforcing steel bars, a template is arranged at the lower part of a reserved gap among the precast reinforced concrete slabs, the precast reinforced concrete slabs are connected as a whole by pouring concrete in the reserved gap; or the template is arranged at the lower part of the reserved gap, and the concretes are poured in the reserved gap and at the upper parts of the precast reinforced concrete slabs to form a precast concrete composite slab. The connection method disclosed by the invention can improve the integrity of an assembled monolithic concrete structure and promote the development of building industrialization.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a connection method for prefabricated reinforced concrete slabs used for prefabricated and assembled monolithic concrete structures. Background technique [0002] Prefabricated concrete structure is suitable for industrialization and is the development direction of housing industrialization. The joint connection structure between prefabricated components in precast concrete structures determines the overall performance of the structure. The existing prefabricated concrete structure nodes are generally the weak link of the structure, which affects the mechanical performance, and the construction process is relatively complicated. Contents of the invention [0003] The invention provides a connection method for prefabricated reinforced concrete slabs with convenient construction and good mechanical performance. The connection method of the prefabricated ...
