Description

Ribbed steel bar connector

Technical Field

The utility model relates to a building technical field, concretely relates to ribbed steel bar connector.

Background

The steel bars are produced by a hot rolling process, and are called round steel bars when the steel bars have a circular cross-section, and are called ribbed steel bars when the steel bars have ribbing on their longitudinal surfaces, which ribbing is used to promote anchoring adhesion between the steel bars and surrounding materials such as concrete.

There are three common connection methods between two adjacent ribbed steel bars:

1) two reinforcing bars are lapped with a proper length and then bound by binding wires, so that enough force can be transferred from one reinforcing bar to the other reinforcing bar.

2) Two steel bars are lapped and then welded, and the welding part can directly transmit force, so that the building length of the steel bars can be shorter.

3) Mechanical connections, as disclosed in the following documents:

patent document 1-US4033502A (1977.7.5) which contains two reinforcing bars in an exothermic molten compound in a cylindrical chamber, and joins the two reinforcing bars together by chemically melting a metal, in a manner that is highly demanding on the skill of the operator;

patent document 2-CN1298995A (2001.6.13), which includes a tubular fastener that fastens two bars with a fastening nut, and requires a tool such as a wrench for assisting operation;

patent document 3-CN206859523U (2018.1.9), the apparatus includes a sleeve, a partition is provided in the center of the sleeve, a set of clamping members and a spring are provided on both sides of the partition, the clamping members clamp the steel bars with ribs inside under the action of the spring, and the two steel bars are connected by the sleeve; similarly, patent document 4-KR101654150B1 (2016.9.9), patent document 5-KR101654145B1 (2016.9.9), and patent document 6-KR101951882B1 (2019.2.25) are also included.

Among the above-described systems, patent documents 3, 4, 5, and 6 are most easily and conveniently handled in use, and have the lowest labor hour and labor cost in field construction, and thus are widely used. These connectors have a spacer fixed to the center of the sleeve to allow two reinforcing bars to be inserted into the sleeve at substantially the same depth to ensure the reliability of the reinforcing bar connection. The design makes the sleeve structure complicated, and has more parts, so the reliability is reduced, and the cost is higher.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

In the embodiments, as shown in FIGS. 1 to 4: the utility model provides a ribbed steel bar connector, includes outer sleeve 100, a set of tight subassembly 200, two sets of respectively are established at the inside both ends of outer sleeve 100 be equipped with elastic component 300 between the tight subassembly 200, tight subassembly 200 is in elastic component 300 is used for chucking ribbed steel bar, every group under the effect tight subassembly 200 includes the jack catch 201 of two at least lamellas, jack catch 201 by towards the one end of elastic component 300 is equipped with the orientation baffle 202 that outer sleeve 100 axle center extends. The baffle 202 of the embodiment can limit the axial position of the ribbed steel bar, so that the insertion depths of the two ribbed steel bars in the outer sleeve 100 are basically the same, and the reliability of connection is ensured; in particular, the baffle 202 is integrated with the jaws 201, and is neither a separate member nor disposed on the outer sleeve 100 or the elastic member 300, which greatly simplifies the structure of the reinforcing bar coupler, thereby reducing the cost.

In the embodiments, as shown in FIGS. 1 to 4: the baffle 202 is fan-shaped. In the embodiment, the single baffle 202 is in a fan shape, the baffles 202 of the group of clamping jaws 201 form a clamping ring structure, and the inner hole of the clamping ring is smaller than the diameter of the ribbed steel bar at the maximum, so that the axial position of the ribbed steel bar is limited.

In the embodiments, as shown in FIGS. 1 to 4: the elastic member 300 is a cylindrical spring and acts on the stopper 202. The baffle 202 of this embodiment is substantially disposed at both ends of the elastic member 300, rather than at the middle of the elastic member 300, so that the functions of the two original elastic members 300 can be realized by using one elastic member 300, and the functions can be realized by using a cylindrical spring, thereby greatly simplifying the structure.

In the example, as shown in fig. 4: one end of the claw 201, which is close to the elastic member 300, is provided with a convex edge 203 extending out of the baffle 202. The baffle 202 of this embodiment sets up in the jack catch 201 substantially, through setting up the spacing ring that chimb 203 formed elastic component 300 naturally, avoids elastic component 300 to slide out from jack catch 201, guarantees the stability of structure.

In the examples, as shown in FIGS. 1 to 3: two ends of the outer sleeve 100 are provided with conical cylinders with small ports, the outer wall of the clamping jaw 201 is a conical surface and is matched with the conical cylinders at the two ends of the outer sleeve 100, and the inner wall of the clamping jaw 201 is provided with a clamping groove 204 for clamping the ribbed steel bar; the cross section of the clamping groove 204 is in an inverted hook shape. The claws 201 slide along the axial end of the outer sleeve 100 under the action of the elastic element 300, so that the ribbed steel bars can be clamped conveniently and quickly.

In the examples, as shown in FIGS. 1 to 3: the outer sleeve 100 is formed by assembling a first cylinder 101 and a second cylinder 102, the first cylinder 101 is connected with the second cylinder 102 through threads, and mounting process grooves 103 are formed in the outer surfaces of the first cylinder 101 and the second cylinder 102. The tooling slots 103 facilitate gripping by a wrench or robot, allowing for mechanized assembly of the outer sleeve 100, thereby improving production efficiency.

In the example, as shown in fig. 2: the pipe orifices at both ends of the outer sleeve 100 are provided with annular flanges 104 facing the axis. The annular flange 104 serves to limit the axial position of the fastening assembly 200, and prevents a certain claw 201 of the fastening assembly 200 from being pushed out of the mouth of the outer sleeve 100, thereby ensuring the reliability of the fastening of the ribbed steel bar.

It is obvious that the above embodiments of the present invention are only examples for illustrating the present invention, and are not intended to limit the embodiments of the present invention. Obvious changes or variations coming within the spirit of the invention are intended to be covered by the scope of the invention.
