Embodiment 1

[0014] The horizontal connection method of prefabricated concrete components, the side of the prefabricated concrete component 1 is pre-embedded with one-to-one corresponding steel bars 2 for mutual connection in the horizontal direction, the exposed part of the steel bars is semi-circular, and the prefabricated concrete components The buried end is fully anchored in the prefabricated concrete member, and the ring-shaped steel bar 3 is placed on the upper part of the steel bar, and it is handed over to the pre-embedded semi-annular steel bars on both sides, and a certain gap is reserved between them. The semi-annular steel bar The longitudinal through-length steel bar 4 is inserted into the intersecting space between the circular steel bar.

Embodiment 2

[0016] In the horizontal connection method of precast concrete components described in Example 1, the side of the precast concrete component has continuous protrusions 5, and the continuous protrusions are mosaic connected with similar products in the horizontal direction.

Embodiment 3

[0018] In the horizontal connection method of precast concrete components described in Example 1, the front and rear sides of the precast concrete components are supported with formwork connected to similar products, and after pouring concrete 6 from the upper part of the formwork, the two prefabricated concrete components are cured. The concrete elements are connected into a whole.

Abstract

The horizontal connection method of precast concrete members. The key to the horizontal connection between precast concrete members is the connection of steel bars. The traditional method is to weld or mechanically connect steel bars, but the connection procedures are complicated, the cost is high, and the connection performance is not easy to guarantee. This will seriously affect the wide application of prefabricated concrete structures. The method of the present invention is to pre-embed one-to-one corresponding steel bars in order to be connected to each other in the horizontal direction in the side of the prefabricated concrete member, and the exposed part of the steel bar It is semi-circular, and its pre-embedded end is fully anchored in the prefabricated concrete member. The annular steel bar is placed on the upper part of the steel bar, and it is handed over to the pre-embedded semi-annular steel bars on both sides, and a certain handover gap is reserved between them. Insert the longitudinal full-length steel bar into the gap between the semi-annular steel bar and the ring-shaped steel bar. The invention is used for horizontal connections between prefabricated concrete structural members.

Description

Technical field: [0001] The invention relates to a method for horizontal connection between prefabricated concrete components, in particular to a horizontal connection method and construction method of prefabricated concrete structural components suitable for housing industrialization. Background technique: [0002] The key to the horizontal connection between precast concrete components is the connection of steel bars. The traditional method is through steel welding or mechanical connection, but the connection procedure is complicated, the cost is high, and the connection performance is not easy to guarantee. This will seriously affect the widespread application of precast concrete structures. Invention content: [0003] The invention provides a horizontal connection method between prefabricated concrete components, which eliminates the need for complicated procedures and mechanical equipment when horizontally connecting prefabricated concrete components, greatly reduces ...
