Description
Technical field
The present invention relates to a kind of bolt reinforcing bar bolt prefabrication and assembly construction concrete foot joints, belong to building engineering field.
Background technique
Component in precast concrete is produced in the factory, and prefabricated component is then transported to construction, into
Row assembling.This mode of construction can greatly improve mechanized construction level, reduce construction personnel, save the construction time, accelerate
Construction speed reduces construction cost.Developing precast concrete is the effective way for realizing building industrialization, can effectively be saved
About resource, reduction environmental pollution are conducive to improve national construction industry modernization development level, have vast potential for future development.
The suspension column of Precast Concrete Frame is the key that influence structural behaviour, and only prefabricated foot joint connection can
It leans on, just can guarantee the safe and reliable of structure.Meanwhile precast concrete suspension column node is also that influence Precast Concrete Frame is fast
The key factor of fast, convenient construction.Currently, conventional prefabricated foot joint mainly has grout sleeve connection suspension column, is bolted
Suspension column, welded connecting suspension column etc..Grout sleeve connects foot joint often on prefabricated foundation there are reinforcing bar is stretched out, and prefabricated post is pre-
Sleeve is buried, then grouting connection, step is more, low efficiency；Being bolted suspension column, there is inconvenient situations at the scene, conventional
Bolt often can only tension, and generally require pre-buried auxiliary steel part, influence joint efficiency and performance；Suspension column is welded to connect to exist
In the narrow range in scene, manual operation is inconvenient, and welding quality is difficult to ensure, inefficiency.
Summary of the invention
It is an object of the invention to propose a kind of bolt reinforcing bar bolt prefabrication and assembly construction concrete foot joint, using " dry type "
Fast Installation is convenient in connection, while using the drawing of reinforcing bar, pressure performance, guaranteeing the anti-seismic performance of foot joint.
To achieve the goals above, this invention takes following technical solutions.
Bolt reinforcing bar bolt prefabrication and assembly construction concrete foot joint, including：Precast concrete column, basic built-in fitting, connection
Reinforcing bar, nut, end nut, pinboard.
Precast concrete column bottom four sides is equipped with prominent step, the prominent step reserved steel bar hole, for across
The connection reinforcing bar.
The basis built-in fitting center is equipped with threaded hole, is embedded on the basis of suspension column position in advance, with the reserved steel bar hole
Relatively, to connect the connection reinforcing bar.
The connection reinforcing bar both ends are equipped with thread segment, insert in the preformed hole, it is pre-buried that bottom thread is screwed into the basis
In the threaded hole of part.
The nut is twisted on the thread segment of the connection reinforcing bar upper end, and the connection reinforcing bar is screwed into the basic built-in fitting
Afterwards, the nut is close on the prominent step.
Bolt board slot is reserved at the prominent step rear portion, and the pinboard passes through the preformed hole in the connection reinforcing bar
Afterwards, it is inserted into the part in the bolt board slot and smears epoxy glue, the reserved pinboard is inserted into, to withstand the end spiral shell
It is female.
The prominent step and the bolt board slot of the precast concrete column adjacent side have certain height difference, avoid passing
It passs internal force excessively to concentrate at same section, be mutated excessive.
The length of the end nut is three times of same specification plain nut, and there is the end plate slightly larger than the nut in one end,
Before the pinboard is inserted into the latch groove, tightly twist on the thread segment of the connection reinforcing bar upper end, the pinboard is inserted into
After the latch groove, the end nut moves back stubborn to the pinboard direction, is tightly attached to the pinboard and exists, described to transmit with this
Connect the pressure of reinforcing bar.
Beneficial effect
Compared with prior art, advantages of the present invention is as follows.
（1）The present invention connects to form prefabrication and assembly construction concrete foot joint, live wet-less operation, installation using " dry type "
High-efficient, construction speed is fast.
（2）The present invention connects reinforcing bar when prefabricated post is not installed, does not install, and after prefabricated post is installed in place, connection reinforcing bar is worn
Preformed hole is crossed, bolt and installation pinboard work are only twisted, it is simple and efficient, it is high-efficient.
（3）The present invention, which connects reinforcing bar, can effectively transmit drawing, pressure, form rigid connection, guarantee heel join node by
Power performance, while reinforcing bar soap-free emulsion polymeization in duct is connected, deformability is good, and energy dissipation ability with higher can be protected effectively
Demonstrate,prove structural behaviour of the foot joint under seismic loading.
Detailed description of the invention
Fig. 1 is component seperated schematic diagram of the invention.
Fig. 2 is foot joint assembling schematic diagram of the invention.
Specific embodiment
The present invention will be further described below with reference to the drawings.
As shown in Figs. 1-2：1 bottom of the precast concrete column four sides is equipped with prominent step 2.
Bolt board slot 4 is reserved at the 2 reserved steel bar hole 3 of prominent step, prominent 2 rear portion of step.
The prominent step 2 of 1 adjacent side of precast concrete column and the bolt board slot 4 have certain height difference.
Basis 5 center of built-in fitting is equipped with threaded hole, is embedded on the basis of suspension column position in advance, with the reserved steel bar hole
3 is opposite.
6 both ends of connection reinforcing bar are equipped with thread segment, and the nut 7 and the end nut 8 are twisted in the connection reinforcing bar 6
Upper end.
To after subscribing position, the connection reinforcing bar 6 is inserted into the reserved steel bar hole 3, bottom for the lifting of precast concrete column 1
Portion is screwed into the threaded hole of the basic built-in fitting 5.
The pinboard 9 is inserted into the part in the bolt board slot 4 after the connection reinforcing bar 6 passes through the preformed hole 3
Epoxy glue is smeared, the pinboard 9 is inserted into.
The nut 7 is tightened, and the prominent step 2 is close to.
The length of the end nut 8 is three times of same specification plain nut, and there is the end plate slightly larger than the nut 7 in one end,
Before the pinboard 9 is inserted into the latch groove 4, tightly twist in it is described connection 6 upper end of reinforcing bar thread segment on, the pinboard
After the 9 insertion latch grooves 4, the end nut 8 moves back stubborn to 9 direction of pinboard, is tightly attached on the pinboard 9.
