Abstract
The invention discloses a steel bar eccentric connection half grouting sleeve and a using method thereof, which belong to the technical field of concrete construction, and can reduce the thickness of protective layers, prevent concrete from cracking, improve project quality, are further beneficial to speed up construction progress, and shorten construction period. The steel bar eccentric connection half grouting sleeve comprises a sleeve body which is provided with a grouting hole and a discharging hole, wherein a thread hole is arranged on the upper portion of the sleeve body, a lower inner cylinder is arranged on the lower portion of the sleeve body, and the thread hole and the lower inner cylinder are communicated with each other. The steel bar eccentric connection half grouting sleeve is characterized in that the thread hole and the lower inner cylinder are eccentrically arranged, and barbs are arranged on the inner surface of the lower inner cylinder. The method for using the steel bar eccentric connection half grouting sleeve is that: the surfaces of exposed steel bars of assembled components are treated through threads, and the exposed steel bars are mechanically connected with the thread holes; exposed steel bars of components to be assembled are inserted into the lower inner cylinder, thereby enabling inserted lengths to meet specified anchorage lengths; and grouting materials are filled into the grouting hole until being filled into the whole inner cylinder, and the strength is calculated through cross sections after the grouting materials achieve specified strength.
Description
Technical field
The invention belongs to concrete construction technical field, particularly relate to a kind of reinforcing bar bias and connect half grout sleeve and using method thereof.
Background technology
In recent years, the application of assembly concrete building is more and more extensive.According to the method for designing of cast in place process, the connection between assembling assembling members relies on the steel reinforcement abutting joints of traditional straight barrel type sleeve, concrete cover can be caused like this to strengthen, concrete is more easily ftractureed, affects workmanship.But this problem is never effectively solved, and once out in the cold.
At present, assembly concrete building in use be all straight barrel type sleeve steel reinforcement abutting joints connect.The connection of reinforcing bar is one of operation the most key in assembly concrete architectural construction technology, therefore, in order to avoid the potential safety hazard that the concrete caused by traditional straight screw sleeve connection is easy to crack, is necessary to design novel reinforced bar sleeve.
Summary of the invention
For prior art Problems existing, the invention provides a kind of reinforcing bar bias and connect half grout sleeve and using method thereof; It not only can reduce protective layer thickness, prevents concrete cracking, improve workmanship, also helps accelerating construction progress, reduces the duration.
To achieve these goals, the present invention adopts following technical scheme, a kind of reinforcing bar bias connects half grout sleeve, comprise the sleeve body with grout hole and plasma discharge hole, the top of described sleeve body is provided with screwed hole, its underpart is provided with lower tub, and described screwed hole is connected with lower tub; Be characterized in described screwed hole and lower tub eccentric setting, the inner surface of lower tub is provided with hangnail.
Described hangnail is the undergauge circulus of the projection that lower tub inner surface is arranged at a certain distance.
Described reinforcing bar bias connects the using method of half grout sleeve, comprises the steps:
Step one: screw thread process is done on the exposed steel bar surface of the assembled component completed, is mechanically connected with described screwed hole;
Step 2: in the lower tub described in being inserted by the exposed steel bar of component to be assembled, make intubating length meet the anchorage length of regulation;
Step 3: pour into grouting material from grout hole, until grouting material overflows from plasma discharge hole, till being full of whole inner core;
Step 4: after the intensity that grouting material reaches regulation, strength checking is carried out to strength checking cross section.
Beneficial effect of the present invention:
Screwed hole of the present invention is convenient to be connected with the exposed steel bar of the assembled component completed, and belongs to mechanical connection, connects very convenient, can complete quickly, be conducive to accelerating construction progress, reduce the duration; The exposed steel bar of component to be assembled inserts lower tub with adopting between sleeve body to be in the milk and is connected, and therefore, the invention belongs to half grouting way.But different from bar connecting mode in existing half grout sleeve, two end bars are not that docking connects, but eccentric docking, namely the center of gravity of two end bars is not at grade.The reinforcing bar center of gravity of one end can be reduced by the present invention, reduce protective layer thickness, prevent concrete cracking, improve workmanship.The present invention is best suited for the bean column node place in assembly concrete building frame construction, and the reinforcing bar that pillar leaks outside is by being connected with the vertical muscle of assembly concrete beam after bending.The present invention not only can make the center of gravity of vertical muscle reduce, and reduces protective layer thickness, prevents span centre concrete cracking, can also improve the energy dissipation ability at bean column node place simultaneously.
In addition, the annular barb of lower tub inner surface of the present invention, and the ring-type shearing groove formed between hangnail, enhance the extraction-resistant behavior of sleeve body, makes not to be drawn out easily during reinforcing bar tension.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of reinforcing bar bias connects half grout sleeve, comprises the sleeve body 1 with grout hole 4 and plasma discharge hole 5, the top of described sleeve body 1 is provided with screwed hole 3, its underpart is provided with lower tub 2, and described screwed hole 3 is connected with lower tub 2; Described screwed hole 3 and lower tub 2 eccentric setting, namely the center of gravity of screwed hole 3 and lower tub 2 is not at grade; The inner surface of lower tub 2 is provided with hangnail 6, and hangnail 6 is not drawn out easily, improves the switching performance of reinforced bar sleeve after making to be connected by high-strength grout between reinforcing bar with sleeve body 1.Described hangnail 6 is the undergauge circulus of the projection that lower tub 2 inner surface is arranged at a certain distance, and reinforcing bar pulling capacity, towards in cylinder, can be resisted in its tip; Form ring-type shearing groove 7 between adjacent hangnail 6, bond after the grouting material consolidation in shearing groove 7 with sleeve body 1, banded adhesive surface provides shearing to stop reinforcing bar to be extracted.
Described reinforcing bar bias connects the using method of half grout sleeve, comprises the steps:
Step one: screw thread process is done on the exposed steel bar surface of the assembled component completed, is mechanically connected with described screwed hole 3;
Step 2: in the lower tub 2 described in being inserted by the exposed steel bar of component to be assembled, make intubating length meet the anchorage length of regulation;
