Abstract
U-shaped reinforcing bar group grouting overlap joint connecting elements, its composition comprises: precast unit (1), described precast unit (1) is reserved with hole (2), described hole is communicated with steam vent (4) with grout hole (3), described precast unit (1) has embedded bar group (5) at described hole (2) two, described embedded bar group (5) is provided with transverse reinforcement (6) along its length, inserts and be connected reinforcing bar (7) in described hole.By grout hole (3) to perfusion grouting material in hole (2), after grouting material setting and hardening can by embedded bar group (5) be connected reinforcing bar (7) and connect as one.The utility model is applicable to the bar connecting between precast unit.
Description
Technical field
The utility model relates to field of civil engineering, particularly relates to the bar connecting component of precast unit.
Background technology
In prefabricated assembled concrete structure, rebar connecting technology is key technology.Existing precast unit rebar connecting technology construction is comparatively complicated, or cost is higher, is unfavorable for the popularization of prefabrication.
The content of invention
The utility model object is to solve the deficiency that prior art exists, provide that a kind of cost is low, easy construction, dependable performance U-shaped reinforcing bar group grouting overlap joint connecting elements.
Above-mentioned purpose is realized by following technical scheme:
U-shaped reinforcing bar group grouting overlap joint connecting elements, its composition comprises: precast unit, described precast unit is reserved with hole, described hole is communicated with steam vent with grout hole, described precast unit has embedded bar group at described hole two, described embedded bar group is provided with transverse reinforcement along its length, inserts and be connected reinforcing bar in described hole.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described hole inner wall surface is matsurface.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, the described part being connected reinforcing bar insertion hole is U-shaped.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described embedded bar group comprises two reinforcing bars.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described embedded bar group is U-shaped with the part being connected bar splicing.
Compared with prior art, the beneficial effects of the utility model are mainly manifested in:
1. bar connecting provided by the utility model is simple to operate, without the need to special installation and facility.
2. reserving hole inner surface is matsurface, is connected reinforcing bar and embedded bar group is U-shaped reinforcing bar, and embedded bar group is provided with transverse reinforcement along its length, makes bar connecting effect more reliable.
3. embedded bar group is positioned at and is connected reinforcing bar two, avoids steel bar force transfer bias, makes member stress more reasonable.
4. basic in work progress is dry operation, is conducive to environmental protection and saves the duration, and saving construction costs.
