Embodiment Construction

[0021] The method for connecting precast concrete slabs of the present invention will be described in detail below with reference to the drawings and embodiments.

[0022] A kind of embodiment of the connection method of the prefabricated concrete slab that the present invention proposes, as figure 1 The side of the precast concrete slab 1 is pre-embedded with fully anchored and semi-annular steel bars 2 exposed, and the semi-annular steel bar 2 is hung with a transverse steel bar 3, and the transverse steel bar 3 and the semi-annular steel bar 2 are reliably connected to ensure The transverse steel bars give full play to the strength. The horizontal reinforcement can be moved and rotated on the semi-circular reinforcement, and the position can be adjusted freely, which is convenient for the transportation and hoisting of the precast concrete slab, and the positioning of the horizontal reinforcement; the horizontal reinforcement is hung on the semi-circular reinforcement in th...

Abstract

The invention discloses a connection method of precast reinforced concrete slabs, and belongs to the technical field of building structures. The connection method is characterized in that reinforcing steel bars which are fully anchored and of which exposed parts are in a shape of a half ring are embedded on lateral sides of the precast reinforced concrete slabs, transverse reinforcing steel bars are hung on the reinforcing steel bars in the shape of the half ring, and lapped in a reserved gap among the precast reinforced concrete slabs; a template is arranged at the lower part of the reserved gap, 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 concrete is 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 concrete panels used in prefabricated and assembled integral 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 of prefabricated concrete slabs with convenient construction and good mechanical performance. The connection method of the prefabricated concrete slabs proposed b...
