Abstract
A U-shaped rebar set grouting lap joint component comprises a prefabricated concrete component (1); a hole (2) is reserved in the prefabricated concrete component (1) and communicates with a grouting hole (3) and a vent hole (4); embedded rebar sets (5) are arranged in the positions, on the two sides of the hole (2), of the prefabricated concrete component (1); transverse rebars (6) are arranged on the embedded rebar sets (5) in the length direction; and a connected rebar (7) is inserted into the hole. Grouting materials are grouted into the hole (2) through the grouting hole (3), and after the grouting materials are solidified and hardened, the embedded rebar sets (5) and the connected rebar (7) are connected into a whole. The U-shaped rebar set grouting lap joint component is suitable for rebar connection between prefabricated concrete components.
Description
Technical field
The present invention relates to field of civil engineering, particularly relate to the bar connecting component of precast concrete.
Background technology
In prefabricated assembled concrete structure, rebar connecting technology is key technology.Existing precast concrete reinforcing bar is even
Connection technology construction is complex, or cost is higher, is unfavorable for the popularization of prefabrication.
The content of invention
Present invention aim at solve prior art exist deficiency, it is provided that a kind of cost is low, easy construction, the U of dependable performance
Shape 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 includes: precast concrete, described precast concrete
Being reserved with hole, described hole connects with grout hole and steam vent, and described precast concrete is at described hole two then
Having embedded bar group, described embedded bar group is provided with transverse steel along its length, is inserted into being connected at described hole
Reinforcing bar.
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, it is U-shaped that described connected reinforcing bar inserts the part of hole.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described embedded bar group includes two reinforcing bars.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described embedded bar group and the portion of connected bar splicing
It is divided into U-shaped.
Compared with prior art, beneficial effects of the present invention is mainly manifested in:
Bar connecting the most provided by the present invention is simple to operate, it is not necessary to special installation and facility.
2. reserving hole inner surface is matsurface, and connected reinforcing bar and embedded bar group are U-shaped reinforcing bar, and embedded bar group
It is provided with transverse steel along its length, makes bar connecting effect relatively reliable.
3. embedded bar group is positioned at connected reinforcing bar two then, it is to avoid steel bar force transfer is eccentric so that member stress is more reasonable.
4. essentially dry operation in work progress, beneficially environmental protection save the duration, and save construction costs.

In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described embedded bar group (5) includes two reinforcing bars.
In described U-shaped reinforcing bar group grouting overlap joint connecting elements, described embedded bar group (5) and connected reinforcing bar (7)
The part of overlap joint is U-shaped.
In conjunction with Fig. 1～Fig. 4, the hole (2) of U-shaped reinforcing bar group grouting overlap joint connecting elements is reserved in precast concrete (1)
Lower end, embedded bar group (5) is positioned at two of hole, and hole (2) connects with grout hole (3) and steam vent (4),
Embedded bar group (5) is provided with transverse steel (6) along its length.It is connected reinforcing bar (7) during construction and inserts hole (2) in advance
Fixed length, and with encapsulant (8), the outward flange in precast concrete (1) gap, lower end is blocked, pass through grout hole
(3) in hole (2), grouting material is irrigated, can be by embedded bar group (5) and connected reinforcing bar (7) after grouting material setting and hardening
Connect as one.
In the present embodiment, the area of section of connected reinforcing bar (7) is not less than the cross section of two reinforcing bars in embedded bar group (5)
Area sum.
