Abstract
The invention discloses the bar connecting mode in a kind of precast shear wall connecting elements, it is characterized in that: the dowel being in the bonding pad between two blocks of prefabricated components is set by straight muscle bending in " U " type " U " type muscle, " U " type muscle is during at least one end is embedded in prefabricated component, form " U " the type dowel extending in prefabricated component end, two blocks of prefabricated components each extend over Chu Ge road " U " type dowel interlaced arrangement and mutually overlaps, formation is in same lengthwise position Shang Ge road rectangle frame, between each road rectangle frame, it is positioned on the position at four angles of rectangle frame the form being connected in series to form rectangle steel reinforcement cage with the most straight muscle.The present invention is applied in precast shear wall connecting elements, and it connects reliable, and globality is strong, meets requirement for bearing capacity, advantageously reduces the realization of prefabricated components kind, beneficially industrialized production.
Description
The application is that Application No. 2014105158261, filing date JIUYUE in 2014 29 days, invention entitled one are pre-
The bar connecting mode of concrete component processed and application, the divisional application of the artificial China Railway No.4 Bureau Group Co., Ltd of application.
Technical field
The present invention relates to bar connecting mode and the application thereof of prefabricated concrete element, more specifically apply at prefabrication and assembly construction
Connected mode between prefabricated concrete element and application thereof in formula building.
Background technology
At present in China's fabricated shear wall house, the connection one routine side of precast concrete shear wall member reinforcing steel bar
Formula is " plug-in type preformed hole grouting reinforcing bar connects overlap joint and connects ", and it is in the lower end of precast concrete embedded bar is reserved with
Wall is the hole of the rough surface such as corrugated or helical form, when, after precast concrete installation, overlap joint reinforcing bar is inserted simultaneously
Enter in hole to setting the lap of splice, in hole, pour into grouting material by the grout hole being connected with hole and steam vent, filling
Slurry i.e. realizes the connection of reinforcing bar after condensing hardening.This bar connecting mode is primarily present problems with:
1, the accurate positioning of the substantive requirements of form scene reinforcing bar of its plug-in type preformed hole, it is impossible to having deviation, otherwise reinforcing bar is difficult to
It is properly inserted in preformed hole, but it practice, the off-position of steel reinforcing bar phenomenon of job site is commonplace, therefore implements to hang at prefabricated components
Before dress, it is necessary to manually correct, but correcting process not only increases workload, reinforcing bar may be made impaired because of rectification simultaneously,
And then affect reinforcement property.
2, preformed hole is an omnidistance blind bore hole, and naked eyes cannot be seen the structure within hole, pour in hole
Grouting material whole during, it is impossible to judging that grouting material the most tightly fills real whole hole, this makes reinforcing bar and prefabricated components
Connect the most uncontrollable, and in cast-in-place structural, concrete needs to vibrate with vibration apparatus, but this
In mode, process of not vibrating, more cause grouting material the most closely knit uncontrollable.
3, the reinforcing bar length during the connection request reinforcing bar of its vertical muscle inserts hole to reach not less than 30 times of bar diameters
The degree of depth, and hole circumferential arrangement tie hoop, the configuration height of tie hoop is not less than the tension reinforcement lap of splice, and this is the most not
It is beneficial to the saving of reinforcing bar.
In prior art, use the construction of overlaid plate type floor connected mode at the floor built for precast shear wall
In, laminated floor slab is the reinforced concrete floor being formed by stacking by precast floor slab and cast-in-situ steel reinforced concrete layer, and this form is mainly deposited
In following problem:
1, according to the regulation of related specifications, the prefabricated components thickness in laminated floor slab is no less than 50mm, and cast-in-place part is thick
Degree is not preferably less than 100mm, and namely floor integral thickness is not less than 150mm, but the slab thickness in cast-in-place structural is normally only
For 100-120mm, it is clear that laminated floor slab thickness relatively cast-in-situ floor thickness adds 50%-25%, and this form considerably increases
Dead load.
2, pre-buried lattice type steel bar in precast floor unit, its reinforcing bar entirety consumption can be big compared with common cast-in-situ floor
Big increase.
3, laminated floor slab needs to carry out at the scene pouring of reinforcing bar binding and concrete, in work progress on-the-spot need substantial amounts of
Labour force operates, and this is unfavorable for improving engineering efficiency.
In sum, in prior art, the form of precast shear wall bar connecting mode and laminated floor slab is primarily present following
Problem:
1, " " grouting construction quality is difficult to inaccurate to control and reserved steel bar location that to affect engineering reliable to plug-in type preformed hole
Degree.
2, laminated floor slab dead load is big, wastes concrete, and its prefabricated components ratio only reaches 50%, and wet trade amount ratio is relatively
Greatly.
3, plug-in type preformed hole grouting reinforcing bar even connect the lattice muscle connected mode with laminated floor slab be two kinds the most not
Same connected mode does not the most have versatility.
Summary of the invention
The present invention is for avoiding the weak point existing for above-mentioned prior art, it is provided that a kind of structural safety is the most prefabricated
