As depicted in figs. 1 and 2, reinforced concrete member 11 is by normal concrete 12 and the moulding by casting of protruding bar 13, and
Reserved temporary construction seam (not shown), post-cast strip is arranged at temporary construction seam, the protruding bar in reinforced concrete member 11
The 13 overlap joint connections in opposite directions along its length at temporary construction seam, mutually two protruding bars 13 of overlap joint connection are along perpendicular to length
Stagger setting in degree direction.That is, two protruding bars 13 that the overlap joint connection of both sides is stitched positioned at temporary construction are applied temporarily
Stagger setting along perpendicular to length direction at work seam, the two is not contacted directly.Post-cast strip includes protruding bar 13 and superelevation
Energy concrete 21 pours the integrative-structure to be formed at temporary construction seam, and reinforced concrete member 11 is linked to be overall knot by post-cast strip
Structure.
Specifically, reinforced concrete member post-cast strip of the present utility model is positioned at facing that reinforced concrete member 11 is reserved
When construction joint at, the opposite overlap joint connection, and the length of overlap joint along its length of protruding bar 13 at temporary construction seam
Shorter, two protruding bars 13 overlapped in opposite directions do not need colligation, welding or mechanically connected, in temporary construction in subsequent handling
Ultra-high performance concrete 21 is poured at seam and forms post-cast strip.Because the protruding bar 13 in post-cast strip only needs overlap joint to connect, and
Without colligation, welding or mechanical connection, stronger bond stress is formed between ultra-high performance concrete 21 and protruding bar 13
The stress of protruding bar 13 is transmitted, can effectively shorten the lap of splice of protruding bar 13, meanwhile, the transverse lap spacing of protruding bar 13
Also without particular/special requirement, protruding bar 13 need not be accurately positioned, it is only necessary to mutually be avoided, and be easy to reinforced concrete member 11
It is pre-formed, so as to significantly save the connection workload of protruding bar 13, construction speed is accelerated, difficulty of construction is reduced.And
And, the concrete for pouring post-cast strip is ultra-high performance concrete 21 so that post-cast strip self-strength and post-cast strip and steel
Bonding strength between reinforced concrete component 11 is not less than the intensity of armored concrete 11, late poured band structure bearing capacity, rigidity, anti-
Fragility energy and anti-fatigue performance are preferable, it is ensured that the overall quality of reinforced concrete member 11.
It is preferred that the lap of splice of protruding bar 13 each other in reinforced concrete member 11 is 6d~12d, (d is
Bar diameter, similarly hereinafter).It is connected, lapped length of steel bar >=25~50d and is welded to connect with conventional colligation, single-sided welding >=
10d, two-sided welding >=5d is compared, and saves a large amount of reinforcing bars.Moreover, saving the connection workload of protruding bar 13.
Certainly, the ultra-high performance concrete for pouring post-cast strip is ultra high performance cementitious, with high-strength
The characteristics such as degree, high tenacity, high-durability, its compressive strength standard value >=120mpa, hold so as to meet the intensity of post-cast strip, structure
Carry the requirement of power, rigidity, cracking resistance and anti-fatigue performance.
It is preferred that due to pouring post-cast strip using ultra-high performance concrete 21, so that post-cast strip self-strength and described
Bonding strength between post-cast strip and reinforced concrete member is not less than the intensity of reinforced concrete member so that post-cast strip has
Standby preferable structural bearing capacity, rigidity, cracking resistance and anti-fatigue performance, it can be ensured that the quality of post-cast strip meets specification will
Ask.
It is preferred that the profile of protruding bar 13 is not limited, the profile of the protruding bar 13 can be linear pattern, linear belt crotch
Type or annular.So as to reduce further the workload of the connection of protruding bar 13, difficulty of construction is reduced.
Please continue to refer to Fig. 1 and Fig. 2, the present embodiment is poured after also disclosing a kind of reinforced concrete member of the present utility model
The construction method of band, comprises the following steps：
Step one：By normal concrete 12 and the moulding by casting of protruding bar 13, reinforced concrete member 11 is formed, and reserve
Temporary construction is stitched so that the protruding bar 13 of reinforced concrete member 11 overlaps a fixed length along its length at temporary construction seam
Degree, because the concrete for being used to pour post-cast strip in subsequent construction process is at ultra-high performance concrete 21, temporary construction seam
The certain length that protruding bar 13 is overlapped is 6d~12d, and d is bar diameter.
Step 2：Reinforced concrete member 11 in installation steps one, is stitched in the temporary construction of reinforced concrete member 11
Place sets pouring template ultra-high performance concrete 21 to form reinforced concrete member post-cast strip, and causes post-cast strip and post-cast strip
Bonding strength between reinforced concrete member 11 is not less than the intensity of reinforced concrete member.
In summary, reinforced concrete member post-cast strip of the present utility model is positioned at facing that reinforced concrete member 11 is reserved
When construction joint at, the opposite overlap joint connection, two overlapped in opposite directions along its length of protruding bar 13 at temporary construction seam
Protruding bar 13 does not need colligation, welding or mechanically connected, and pours very-high performance in subsequent handling at temporary construction seam and mixes
Solidifying soil 21 forms post-cast strip.Because the protruding bar 13 in post-cast strip only needs overlap joint to connect, without colligation, welding or machine
Tool is connected, and forms stronger bond stress between ultra-high performance concrete 21 and protruding bar 13 to transmit the stress of protruding bar 13,
The lap of splice of protruding bar 13 can effectively be shortened, meanwhile, the transverse lap spacing of protruding bar 13 is also without particular/special requirement, overhanging steel
Muscle 13 need not be accurately positioned, it is only necessary to mutually be avoided, and be easy to reinforced concrete member 11 pre-formed, so as to significantly save
The connection workload of protruding bar 13 has been saved, construction speed has been accelerated, reduces difficulty of construction.Moreover, for pouring post-cast strip
Concrete is ultra-high performance concrete 21 so that between post-cast strip self-strength and post-cast strip and reinforced concrete member 11
Bonding strength is not less than the intensity of armored concrete 11, late poured band structure bearing capacity, rigidity, cracking resistance and anti-fatigue performance
Preferably, it is ensured that the overall quality of reinforced concrete member 11.Reinforced concrete member post empiricism side of the present utility model
Method, pours to form reinforced concrete member using normal concrete 12 and protruding bar 13 first, while reserved temporary construction seam,
The laterally opposite overlap joint connection of protruding bar 13 at temporary construction seam；Then ultra-high performance concrete is poured at temporary construction seam
21 form post-cast strip, and reinforced concrete member 11 is linked to be overall structure by the post-cast strip.The construction method is simple to operate, construction effect
Rate is high, the quality of post-cast strip is ensure that, with preferably promotional value.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the utility model scope
Calmly, the those of ordinary skill in the utility model field does according to the disclosure above content any change, modification, belonging to right will
Seek the protection domain of book.
