Description
Technical field
The invention belongs to technical field of civil engineering, and in particular to a kind of O-shaped steel bar connecting structure.
Background technology
At present, using the viewpoint of structuring, industrialized pattern, in scale, the level of seriation, the few soil of implementation,
Construction without soil, efficient, low price engineering, the just developing direction as the green highway construction of China.Wherein, small structures lightness
Complete set technology is to implement green highway construction, the key component of highway industrialization construction.By exploring for many years, although this technology
Tremendous development is obtained, demonstration effect is good, but still existed many not enough：Such as scale construction is not enough, critical structures are vacant,
Controlling construction is delayed and theoretical property breaks through and lacked.
Wet seam bar connecting between precast concrete is always the problem in domestic design, construction：Reinforcing bar is pressed
When specification is overlapped, welded by specification, wet seam is wide, and workload is excessive, and according to other connected modes, connection effect again can not
Ensure.
The content of the invention
The purpose of the present invention is exactly to provide a kind of O-shaped steel bar connecting structure to solve the above problems.
The purpose of the present invention is achieved through the following technical solutions：
A kind of O-shaped steel bar connecting structure, including the U-shaped reinforcing bar that two rows are located on different precast concretes, it is described
The U-shaped reinforcing bar of two rows sets multiple pad reinforcing bars, and pass through to intersecting to form O-shaped bar construction to overlapping in the O-shaped bar construction
Irrigate the formation anchorage formula connection of pressure-bearing concrete.
Further, the O-shaped bar construction of the described equidistant vertical wraparound of pad reinforcing bar is set.
Further, described pad reinforcing bar is connected with described O-shaped bar construction colligation or spot welding, by O-shaped reinforcing bar knot
Structure series connection is an entirety, forms netted stress surface.
Further, described pad reinforcing bar should meet the regulation to distributing bar and the requirement of adjustment interface pressure,
Away from for 40-150mm, a diameter of 12-25mm, symmetrical arrangement is pressed on O-shaped reinforcing bar.
Further, the spacing between described U-shaped reinforcing bar is 75-100mm.
Further, described pressure-bearing concrete should meet requirement of the interface pressure-bearing to intensity, and strength grade is not less than
C50, axial compressive strength standard value is not less than 32.4Mpa.
The present invention proposes a kind of new connecting structure of reinforcing bar, and using O-shaped bar construction, inside sets pad reinforcing bar, with O
The colligation of steel bar structure or spot welding connection, are an entirety by the series connection of O-shaped bar construction, form netted stress surface, then by filling
The formation anchorage formula connection of pressure-bearing concrete is noted, precast concrete is connected firmly.
There is the present invention pressure between unique operation principle, precast concrete directly can be passed by joint concrete
Pass；Pulling force between precast concrete is first converted into reinforcing bar pulling force, is converted mainly on netted stress surface mixed to pressure-bearing
Coagulate soil radial pressure, and with to being balanced each other to the pressure on netted stress surface.Thus, pressure-bearing concrete no matter transmit pressure or
Pulling force, itself is in pressured state all the time.
The present invention changes the traditional mode and force-transmission mechanism of bar connecting, and the wet joint gap that connection is formed greatly subtracts
It is small, it is that traditional reinforcing bar does not weld less than the 1/2 of wet seam, simplifies bar connecting and component seam, reduce materials'use, drops
Low construction costs, workload is substantially reduced, and the building site for realizing prefabrication concrete component is quickly connected, and has promoted bridge
Industrialize the development of building technology.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
Such as Fig. 2, precast concrete 1, thick 24cm, end is provided with U-shaped reinforcing bar 2, and the connection of U-shaped reinforcing bar 2 uses welding,
The wide 50cm of wet seam is connected, workload is excessive, and efficiency of construction is low.
Such as Fig. 1, Fig. 3, U-shaped reinforcing bar 2 pair of two rows on different precast concretes 1 is intersected to form into O to overlapping
Pad reinforcing bar 4 is set in steel bar structure 3, the O-shaped bar construction 3, and connected by irrigating the formation anchorage formula of pressure-bearing concrete 5
Connect, two rows, to not welded between U-shaped reinforcing bar 2, are mutually space crossed, spacing 7.5cm, pad reinforcing bar 4 is arranged at O-shaped reinforcing bar
In structure 3 and with its colligation, the series connection of O-shaped bar construction 3 is integrated, a netted stress surface is formed, pad reinforcing bar 4 is a diameter of
20mm, radical 6, the equidistant O-shaped bar construction 3 of vertical wraparound is set, and pressure-bearing concrete 5 is mixed using C50 microdilatancies Self-leveling
Solidifying soil.
Pressure between reference picture 4, precast concrete 1 can be transmitted directly by joint concrete；Precast concrete 1
Between pulling force be first converted into reinforcing bar pulling force, the radial pressure to pressure-bearing concrete is converted mainly on netted stress surface, and
With to being balanced each other to the pressure on netted stress surface, thus, no matter pressure-bearing concrete transmits pressure or pulling force, itself is in all the time
Pressured state.Connected using this structure, it is not necessary to weld, wet joint gap is only 25cm, site operation workload greatly subtracts
Few, efficiency of construction is improved.
