Description
Technical field
The utility model 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, scale, seriation level on, implement few soil,
Without soil, just efficient, low price engineering construction, the developing direction as China's green highway construction.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 many deficiencies still be present：As scale build deficiency, critical structures it is vacant,
Controlling construction hysteresis and theoretical property, which break through, to be 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.
Utility model content
The purpose of this utility model is exactly to provide a kind of O-shaped steel bar connecting structure to solve the above problems.
The purpose of this utility model is achieved through the following technical solutions：
A kind of O-shaped steel bar connecting structure, including the U-shaped steel muscle that two rows are located on different precast concretes, it is described
Two row's U-shaped steel muscle set multiple pad reinforcing bars, and pass through to intersecting to form O-shaped bar construction to overlapping in the O-shaped bar construction
Irrigate pressure-bearing concrete and form the connection of anchorage formula.
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 requirement to the regulation and adjustment interface pressure of distributing bar,
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 steel muscle 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 are not less than 32.4Mpa.
The utility model proposes a kind of new connecting structure of reinforcing bar, and using O-shaped bar construction, inside sets pad steel
Muscle, it is connected with O-shaped bar construction colligation or spot welding, is an entirety by the series connection of O-shaped bar construction, forms netted stress surface, then
The connection of anchorage formula is formed by irrigating pressure-bearing concrete, precast concrete is connected firmly.
The utility model has unique operation principle, and the pressure between precast concrete can be directly by joint concrete
Transmit；Pulling force between precast concrete is first converted into reinforcing bar pulling force, is converted mainly on netted stress surface to pressure-bearing
The radial pressure of concrete, and with to being balanced each other to the pressure on netted stress surface.In this way, no matter pressure-bearing concrete transmits pressure
Or pulling force, itself is in pressured state all the time.
The utility model changes the traditional mode and force-transmission mechanism of bar connecting, connects the wet joint gap of formation greatly
Reduce, do not weld less than the 1/2 of wet seam for traditional reinforcing bar, simplify bar connecting and component seam, reduce materials'use,
Construction costs is reduced, workload substantially reduces, and the building site for realizing prefabrication concrete component quickly connects, and has promoted bridge
Beam industrializes the development of building technology.

Embodiment
The utility model 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 steel muscle 2, the connection of U-shaped steel muscle 2 using welding,
The wide 50cm of wet seam is connected, workload is excessive, and efficiency of construction is low.
Such as Fig. 1, Fig. 3, the U-shaped steel muscle 2 that two rows are located on different precast concretes 1 to overlapping to intersecting to form O
Steel bar structure 3, the O-shaped bar construction 3 is interior to set pad reinforcing bar 4, and forms anchorage formula company by irrigating pressure-bearing concrete 5
Connect, two rows between U-shaped steel muscle 2 to not welding, and to be 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, forms a netted stress surface, pad reinforcing bar 4 is a diameter of
20mm, radical 6, the equidistant O-shaped bar construction 3 of vertical wraparound are set, and pressure-bearing concrete 5 is mixed using C50 microdilatancy Self-levelings
