Description
Technical field
The present invention relates to a kind of bolt reinforcing bar bolt assembly concrete concrete frame 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 key of Precast Concrete Frame performance is that bean column node connects, and only prefabricated bean column node connection can
It leans on, just can guarantee the safe and reliable of structure.Meanwhile precast concrete concrete frame joint is also to influence precast concrete frame knot
The key factor of quick, the convenient construction of structure.Currently, conventional prefabricated connecting node pours " wet " connecting node, bolt after mainly having
Connecting node, welding connection node etc..After pour " wet " connecting node often prefabricated beam-ends there are stretch out reinforcing bar, seriously affect pre-
Beam processed, column lifting efficiency；For bolt connection node at the scene there is inconvenient situation, conventional stud often can only be by
It draws, and generally requires pre-buried auxiliary profile steel joint, influence joint efficiency and performance；Welding connection node narrow model at the scene
In enclosing, 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 assembly concrete concrete frame joint, using " dry
Formula " connection, is convenient for Fast Installation, while node area is integral prefabricated with precast beam, guarantees strong node, the difficulty at the scene of reducing, benefit
Bracket can be reduced with prefabricated post, reduces installation cost.
To achieve the goals above, this invention takes following technical solutions.
Bolt reinforcing bar bolt prefabrication and assembly construction concrete foot joint, comprising: precast concrete column, precast beam, prefabricated node,
Connect reinforcing bar, nut, end nut, pinboard.
Four sides is equipped with prominent step at the top and bottom of the precast concrete column, and the prominent step reserved steel bar hole is used
In across the connection reinforcing bar；Bolt board slot is reserved at the prominent step rear portion, to be inserted into the pinboard；It is described prefabricated mixed
The prominent step and the bolt board slot of solidifying earth pillar adjacent side have certain height difference, avoid transmission internal force at same section
It excessively concentrates, is mutated excessive.
The precast beam with the prefabricated node is integral prefabricated is integrated, reduce the difficulty of site operation；The prefabricated section
Point reserves elongated reinforced hole, opposite with the reserved steel bar hole, to pass through the connection reinforcing bar.
The precast concrete column is close to the upper and lower surface of the prefabricated node, forms fundamental node type of attachment.
The connection reinforcing bar both ends are equipped with thread segment, pass through the reserved steel bar hole and the elongated reinforced hole, bottom are tight
It on the pinboard for pasting precast concrete column described in lower part, and holds out against, to transmit the pressure of the connection reinforcing bar.
The nut is twisted on the thread segment of the connection reinforcing bar, and the nut is close on the prominent step, to pass
Pass the pulling force of the connection reinforcing bar.
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 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 on the pinboard, 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) present invention forms prefabrication and assembly construction concrete frame bean column node using " dry type " connection, live wet-less operation,
Installation effectiveness is high, and construction speed is fast.
(2) whether present invention connection reinforcing bar or not when prefabricated post is not installed, 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) present invention connection reinforcing bar can effectively transmit drawing, pressure, form rigid connection, and node area is prefabricated, reduce scene
Task difficulty guarantees node quality, while connecting reinforcing bar soap-free emulsion polymeization in duct, and deformability is good, antidetonation consumption with higher
Energy ability, can effectively ensure that the structural behaviour under seismic loading.
Detailed description of the invention
Fig. 1 is precast concrete column schematic diagram of the invention.
Fig. 2 is component seperated schematic diagram of the invention.
Fig. 3 is assembling schematic diagram of the invention.
Specific embodiment
The present invention will be further described below with reference to the drawings.
The 1 top and bottom four sides of precast concrete column is equipped with prominent step 2 as shown in Figure 1:, and the prominent step is pre-
