Description
Technical field
The utility model relates to the steel bar connecting structure of prefabricated concrete element, is more particularly the syndeton be applied in prefabrication between prefabricated concrete element.
Background technology
At present in China's fabricated shear wall house, a kind of usual manner of connection of precast concrete shear wall member reinforcing steel bar is " plug-in type preformed hole grouting reinforcing bar connects overlap joint and connects ", it is reserved with in the lower end of precast unit embedded bar the hole that inwall is the rough surface such as corrugated or helical form, when after precast unit installation, overlap reinforcing bar to insert in hole to setting lap length simultaneously, in hole, pour into grouting material by be connected with hole grout hole and steam vent, after grouting material setting and harden, namely realize the connection of reinforcing bar.Mainly there is following problem in this bar connecting mode:
1, the accurate positioning of the on-the-spot reinforcing bar of the substantive requirements of form of its plug-in type preformed hole, deviation can not be had, otherwise reinforcing bar is difficult to accurately insert in preformed hole, but in fact, the off-position of steel reinforcing bar phenomenon of job site is commonplace, therefore before lifting implemented by prefabricated units, must manually correct, but correcting process not only increases workload, reinforcing bar may be made impaired because correcting simultaneously, and then affect reinforcement property.
2, preformed hole is an omnidistance blind bore hole, naked eyes cannot see the structure of hole inside, pouring in the whole process of grouting material in hole, cannot judge whether grouting material tightly fills with real whole hole, and this makes the connection of reinforcing bar and prefabricated units whether reliably uncontrollable, and in cast-in-place structural, concrete needs to vibrate with vibration apparatus, but in this fashion, whether process of not vibrating, more cause grouting material closely knit uncontrollable.
3, the reinforcing bar length that the connection request reinforcing bar of its vertical muscle inserts in hole will reach the degree of depth being not less than 30 times of bar diameters, and hole circumferential arrangement spiral stirrup, the configuration height of spiral stirrup is not less than tensile reinforcement lap length, and this is obviously unfavorable for the saving of reinforcing bar.
In prior art, adopt at the floor built for precast shear wall in the construction of overlaid plate type floor connected mode, laminated floor slab is the reinforced concrete floor be formed by stacking by precast floor slab and cast-in-situ steel reinforced concrete layer, and mainly there are the following problems for this form:
1, according to the regulation of related specifications, prefabricated units thickness in laminated floor slab should not be less than 50mm, cast-in-place segment thickness should not be less than 100mm, namely floor integral thickness is not less than 150mm, but the slab thickness in cast-in-place structural is generally only 100-120mm, obviously, laminated floor slab thickness comparatively 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 steel bar overall consumption can greatly increase compared with common cast-in-situ floor.
3, laminated floor slab needs to carry out at the scene building of reinforcing bar binding and concrete, on-the-spotly in work progress needs a large amount of labours to operate, and this is unfavorable for improving engineering efficiency.
In sum, in prior art mainly there is following problem in the form of precast shear wall bar connecting mode and laminated floor slab:
1, " " grouting construction quality is not easily located control and reserved steel bar inaccurately affects engineering reliability to plug-in type preformed hole.
2, laminated floor slab dead load is large, and waste concrete, its prefabricated units ratio only reaches 50%, wet trade amount large percentage.
3, plug-in type preformed hole grouting reinforcing bar connects and connects with the lattice muscle connected mode of laminated floor slab that to be that two kinds of diverse connected modes are mutual do not have a versatility.
