Abstract
The invention discloses one kind for precast wall body component node reinforcing bar grouting connection type in engineering.The connection type is in the pre-buried straight screw sleeve in upper wall body bottom, pre-buried base expanding and base expanding type grout sleeve at the top of lower wall body, pre-buried base expanding and base expanding type grout sleeve elder generation pregrouting at the top of lower wall body, connection reinforcing bar is screwed into upper wall body sleeve afterwards, and then lifting upper wall body will connect in reinforcing bar insertion lower wall body base expanding and base expanding jacket cylinder.
Description
Technical field
The present invention relates to building fields, more particularly, to the connection method for being used for prefabricated components reinforcing bar in modular architectural.
Background technique
It is all utilized in the pre-buried grout sleeve in upper wall body bottom in precast wall body component grouting connection in engineering at present, is hung
Bottom wall steel bar is inserted into sleeve after playing wall, is in the milk again after the completion of lifting.
The application mainly introduces a kind of for precast wall body component node reinforcing bar grouting connection type in engineering.The connection
Mode is pre-buried base expanding and base expanding type grout sleeve, lower wall body top at the top of the pre-buried straight screw sleeve in upper wall body bottom, lower wall body
The pre-buried base expanding and base expanding type grout sleeve elder generation pregrouting in portion, the rear reinforcing bar that connects are screwed into upper wall body sleeve, and then lifting upper wall body will even
It connects in reinforcing bar insertion lower wall body base expanding and base expanding jacket cylinder.
Summary of the invention
Problem to be solved by this invention is, for it is above-mentioned in the prior art the shortcomings that, propose innovation scheme, especially one
Kind can effectively improve the scheme that each module is difficult to install in modular architectural.
To solve the above problems, the scheme that the present invention uses is as follows: a kind of connection method for prefabricated components reinforcing bar,
It is characterized in that, including pre-buried straight screw sleeve, the threaded connection reinforcing bar in end, base expanding and base expanding shape grout sleeve；By pre-buried straight thread set
Cylinder is cast in the bottoms of top prefabricated components, and base expanding and base expanding shape grout sleeve is cast in the top of lower part prefabricated components, when installation
Grouting material is poured into base expanding and base expanding shape grout sleeve, the threaded connection reinforcing bar in end is screwed into pre-buried straight screw sleeve, lifts top
Prefabricated components, so that prefabricated components compacting in top exists in the lower end insertion base expanding and base expanding shape grout sleeve of the threaded connection reinforcing bar in end
On the prefabricated components of lower part, solidified to grouting material.
Further, the connection method of prefabricated components reinforcing bar is used for according to above-mentioned design scheme, which is characterized in that described
Pre-buried straight screw sleeve is placed in top prefabricated components bottom, and sleeve upper end and wall vertical reinforcement are tightened, coagulation is then poured
Soil, prefabricated components molding in upper back to be solidified.
Further, the connection method of prefabricated components reinforcing bar is used for according to above-mentioned design scheme, which is characterized in that described
After placing base expanding and base expanding shape grout sleeve at the top of the prefabricated components of lower part, sleeve lower end and wall vertical reinforcement are tightened, then poured mixed
Solidifying soil, after to be solidified, the molding of lower part prefabricated components.
Further, the connection method of prefabricated components reinforcing bar is used for according to above-mentioned design scheme, which is characterized in that described
Base expanding and base expanding shape grout sleeve is that upper end opening is small, and lower end cross section is big, the trapezoidal structure of vertical cross-section.
Technical effect of the invention is as follows: the pre-buried screw shell of upper wall body and with internal steel concrete supporting, connect matter
Amount is reliable；Sleeve is flushed with wall bottom surface, on lifting component without influence；Component is screwed into connection reinforcing bar after slinging, it is convenient to construct, and keeps away
Exempt from lifting and causes bar bending.Lower part precast wall body grout sleeve is first in the milk, and can greatly improve grouting quality, guarantees internal
It is in the milk closely knit；Connection reinforcing bar is inserted into after sleeve grouting, internal additional size squeezes out, and sleeve grouting self-compaction ensure that grouting
Construction quality.Sleeve is base expanding and base expanding type, and bottom is variable cross-section cylinder after grouting material molding, plays the high performance of slurry compression strength,
Greatly improve connection tensile property.The base expanding and base expanding shape grout sleeve of the application not only passes through the acquisition of the cohesive force between grouting and reinforcing bar
Tensile property also makes concrete grouting be pressurized to improve sleeve tensile property by the sleeve of base expanding and base expanding shape structure.

Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
A kind of embodiment: connection method for prefabricated components reinforcing bar, which is characterized in that including pre-buried straight screw sleeve,
The threaded connection reinforcing bar in end, base expanding and base expanding shape grout sleeve；Pre-buried straight screw sleeve is cast in the bottom of top prefabricated components, it will
Base expanding and base expanding shape grout sleeve is cast in the top of lower part prefabricated components, and pre-buried straight thread set is placed in top prefabricated components bottom
Cylinder, sleeve upper end and wall vertical reinforcement is tightened, then casting concrete, prefabricated components molding in upper back to be solidified；It is described
After placing base expanding and base expanding shape grout sleeve at the top of the prefabricated components of lower part, sleeve lower end and wall vertical reinforcement are tightened, then poured mixed
Solidifying soil, after to be solidified, the molding of lower part prefabricated components.Grouting material is poured into base expanding and base expanding shape grout sleeve when installation, by end band spiral shell
Line connection reinforcing bar is screwed into pre-buried straight screw sleeve, lifts top prefabricated components, so that the lower end of the threaded connection reinforcing bar in end
It is inserted into base expanding and base expanding shape grout sleeve, top prefabricated components are compacted on the prefabricated components of lower part, are solidified to grouting material, the prefabricated structure in top
Part connect completion with lower part prefabricated components.
Concrete technology includes the following steps: 1) to be in the milk in advance in lower wall body grout sleeve, at this time due to upper wall body
Connection reinforcing bar is not yet inserted into, and sleeve grouting is easier to closely knit；2) lifting top precast wall body slings back wall bottom surface at vertical shape body
Liftoff certain distance；3) the threaded reinforcing bar in end is screwed into the precast wall body screw shell of top, is screwed into length and meets regulation most
Small length, to guarantee switching performance；4) top precast wall body is hung to above the precast wall body of lower part after reinforcing bar is twisted, and is connected to just simultaneously
It is inserted into lower wall body grout sleeve.
