Abstract
The universal steel bar connecting joints of double sleeves of connection among a kind of, include sleeve, an intermediate connector and two locating parts of two open at one end other end closings, the blind end of two sleeves is all provided with the bellmouth passed through for reinforcing bar, locating part is fastened on end reinforced, and intermediate connector both ends are flexibly connected with two sleeve opening ends respectively.The utility model can not only make two reinforcing bar radial direction universal adjustments waiting, and two reinforcing bar axial direction waiting spacing can be adjusted, and adjustable range is big, assembled architecture steel reinforcement abutting joints is become easy, and efficiently, reliably, intensity is high, and applicability is good.
Description
Technical field
The utility model belongs to construction engineering technical field, and in particular to the universal reinforcing bar of double sleeves of connection connects among a kind of
Connect node.
Background technology
Industrialize the inexorable trend that assembled architecture is construction industry development, but prefabricated components bar connecting in assembled architecture
Technical barrier, it has also become restrict the bottleneck that is further lifted of element precast rate.Although the rebar connector of current relatively accreditation
It is grout sleeve, but lifting required precision of the grout sleeve to prefabricated components is very high, it is desirable to prefabricated components bottom when mounted
Fully horizontally, do not rock, can allow all reinforcing bars simultaneously insertion sleeve, operation difficulty is very large, at the same grout sleeve according to
Relying high strength grout, cost is higher, and the allotment and construction of grouting material need certain professional skill, and quality is not easy to control,
In addition, after grouting material solidification, easily blended by reinforcing bar, structural strength is low, and ageing resistace is poor.
The content of the invention
Technical problem to be solved in the utility model is：Solve the above-mentioned problems of the prior art, and provide a kind of
The universal steel bar connecting joints of double sleeves of centre connection, substitute grout sleeve and normal concrete pours, and structural strength is higher, no
Special high strength grout is relied on, cost is lower, and volume is smaller, and reliability is higher, and quality is more easy to control, and can particularly realize
Universal connection between two reinforcing bars, installation difficulty is greatly reduced, lift assembled architecture element precast rate.
The technical solution adopted in the utility model is：
The universal steel bar connecting joints of double sleeves of connection among a kind of, include the set of two open at one end other end closings
Cylinder, an intermediate connector and two locating parts, the blind end of two sleeve is all provided with the bellmouth passed through for reinforcing bar, described
Locating part is fastened on end reinforced, and the intermediate connector both ends are flexibly connected with two sleeve opening ends respectively.
In above-mentioned technical proposal, described intermediate connector is studs, the both ends of studs respectively with two sleeves
Opening end is threadedly coupled.
In above-mentioned technical proposal, described locating part is Ball faced nut, and the connection of Ball faced nut and barrel bore uses ball
The conical surface connects.
In above-mentioned technical proposal, the locating part is fastened on end reinforced use and is threadedly coupled or welds, and even
Connect and be fixed on end reinforced locating part and be located at barrel bore.
In above-mentioned technical proposal, concrete structure that the intermediate connector both ends are flexibly connected with two sleeve opening ends respectively
It is：The periphery at intermediate connector both ends is threadedly coupled with being used on the inside of sleeve opening end.
Operation principle and advantageous effect：
In node of the present utility model, two sleeve open at one end other ends closing, blind end outwardly, is provided with bellmouth, opens
Inwardly, two reinforcing bars waiting are each passed through the bellmouth of two sleeve blind ends for mouthful end, and through the end reinforced ball that is connected
For face nut as locating part, contact of the Ball faced nut with barrel bore is ball taper-face contact, so, two reinforcing bars waiting and two sleeves
Connection be universal connection, radially movable scope is big, greatly reduces the peace of prefabricated components steel reinforcement abutting joints in assembled architecture
Difficulty is filled, solves the technology hardly possible that existing stationary machine sleeve and grout sleeve do not adapt to assembled architecture steel reinforcement abutting joints
Topic, the significant increase prefabricated rate of assembled architecture component.Meanwhile on the inside of two sleeve of the present utility model by studs this
One intermediate connector is threadedly coupled, and rotation studs can adjusts the spacing of two reinforcing bars waiting.So, this practicality is new
Type can not only make two reinforcing bar radial direction universal adjustments waiting, and two reinforcing bars waiting can be made axially to be adjusted, and adjustable range is big, makes
Assembled architecture steel reinforcement abutting joints become easy, and efficiently, reliably, intensity is high, and applicability is good.
Brief description of the drawings：
Fig. 1 is the utility model section of structure.
In figure, the 1-the first sleeve, 2-studs, 3-second sleeve, 4-Ball faced nut, 5-reinforcing bar, 6-taper
Hole.
Embodiment：
The utility model section of structure shown in Figure 1, the first sleeve and second sleeve are all that one end is closed in one end
Uncovered structure, one end of two sleeves closing are provided with the bellmouth passed through for reinforcing bar waiting, and among one end confession of two sleeves opening
Connection such as part studs is inserted in threaded connection, after two reinforcing bars waiting are each passed through two sleeve bellmouths, passes through end reinforced
The fixed Ball faced nut of screw thread installation is as locating part, because two reinforcing bars waiting pass through the bellmouth of sleeve, it is thus achieved that reinforcing bar
With the universal connection of sleeve, the steel reinforcement abutting joints allowable error than existing stationary machine sleeve expands 100 times, that is, installation hardly possible
Degree reduces by 100 times.And the rotation of intermediate connector studs can change the axial distance of two reinforcing bars waiting.Above-mentioned two is waiting
The radial direction universal adjustment of reinforcing bar and it is adjusted axially particularly suitable for assembled architecture.
