Description
Technical Field
The invention belongs to the technical field of building components, and particularly relates to a steel bar connector.
Background
The term "reinforcing bar coupler" is used to connect the ends of two reinforcing bars, and the reinforcing bars are mainly thread steel.
As is known in the art, the use of reinforced concrete is commonly required for various types of construction facilities above ground, underground or even underwater, without the use of the aforementioned thread steels. Prior to the pouring of concrete, a framework of rebars is constructed (a construction worker is accustomed to "tying bars"). If the original, i.e. traditional construction method is adopted, two deformed steel bars to be butted are welded and fixed to each other at the end parts in the process of constructing the steel reinforcement framework, and the method has the following self-evident defects: firstly, because welding equipment such as an electric welding machine needs power supply support, the welding equipment is critical to construction sites, for example, power supply must be led to the welding equipment at a steel bar butt joint station through a cable or a similar feed line, and the work of leading the power supply to the welding equipment is troublesome and has safety; secondly, welding needs to be operated by qualified personnel, so that the welding tool has the same criticality to operators; thirdly, the welding efficiency is relatively low, so that the progress of the project is influenced to a certain extent; fourthly, the operation intensity of welding workers is high, and the consistency of welding quality is difficult to guarantee.
The above disadvantages can be largely avoided by using the steel bar connector, and technical information related to the steel bar connector can be found in the published Chinese patent documents, which are briefly listed as "a steel bar connecting component" recommended by CN208830600U and "steel bar quick connector" provided by CN210032349U, because the two patent structures are split, namely, the steel bar quick connector consists of a first cylindrical sleeve, a second cylindrical sleeve and a sealing connecting cylinder, when in use, one end of one steel bar of two steel bars to be butted is inserted into a first cylindrical sleeve cavity of the first cylindrical sleeve with threads on the inner wall, one end of the other steel bar of the two steel bars is inserted into a second cylindrical sleeve cavity of the second cylindrical sleeve with threads on the inner wall, and the opposite ends of the first cylindrical sleeve and the second cylindrical sleeve are connected by the sealing connecting cylinder component, not only is the connection efficiency and effect affected, but also the operation is relatively troublesome.
Typically, CN204878162U discloses "a locking sleeve structure for quick connection of steel bars, which is disclosed in the specification 0011 to 0013 of the patent: although having the advantage of convenient processing of the inner thread taper sleeve and the outer thread taper sleeve, the overall structure is relatively complex and the operation is still troublesome due to the need to screw the inner thread taper sleeve and the outer thread taper sleeve into one unit.

Referring to fig. 3 and 4, fig. 3 shows the first steel bar end introduction anti-retraction mechanism receiving hole i 13 and the second steel bar end introduction anti-retraction mechanism receiving hole ii 14 that are not blocked, and fig. 4 shows that the first steel bar end introduction anti-retraction mechanism receiving hole i 13 and the second steel bar end introduction anti-retraction mechanism receiving hole ii 14 are well covered by polishing process or blocking, such as blocking welding, and then polishing, that is, they are integrated with the outer wall of the steel bar end insertion sleeve 1.
As shown in fig. 2, a first spherical cavity i 131 (also referred to as a "hemispherical cavity") is formed at an end of the first rod end introduction anti-retraction mechanism accommodating hole ii 13 facing the first rod end insertion hole i 111, a second spherical cavity ii 141 (also referred to as a "hemispherical cavity") is formed at an end of the second rod end introduction anti-retraction mechanism accommodating hole ii 14 facing the second rod end insertion hole ii 112, the first steel ball i 22 is engaged with the first spherical cavity i 131, and the second steel ball ii 32 is engaged with the second spherical cavity ii 141.

Referring to fig. 4 in conjunction with fig. 1 and 2, fig. 4 shows a first steel bar 4 and a second steel bar 5 with the same diameter, when the first steel bar 4 is used in a construction site, the end of the first steel bar 4 made of deformed steel is inserted into the first steel bar end insertion hole i 111, during the insertion process, the first steel ball i 22 is pushed by the first steel bar 4 to force the first spring i 21 to compress, the first steel ball i 22 temporarily exits the first steel bar end insertion hole i 111, i.e. retracts into the first steel bar end and guides into the anti-retraction mechanism accommodating hole ii 13, so that the first steel bar 4 is smoothly inserted until the end surface of the first steel bar is blocked by the insertion hole partition wall 12, after the first steel bar 4 is inserted, the first steel ball i 22 is ejected out by the restoring force of the first spring i 21 and extends into the first steel bar end insertion hole i 111, i.e. enters the concave cavity between two adjacent threads of the deformed steel bar, the inserted first steel bar is limited, so that the first steel bar 4 cannot move and bounce, and further cannot exit the first steel bar end insertion hole I111, and therefore the first steel bar 4 and the first steel bar end insertion hole I111 are connected in an inserted mode. The insertion manner of the second steel bar 5 and the second steel bar end insertion hole II 112 is the same as that of the first steel bar 4, and therefore, the description is omitted. The tensile strength of the first steel bar 4 and the second steel bar 5 after being connected by the invention can completely meet the requirements of Chinese national standards such as GB1499.2-2007, for example, the tensile strength reaches 540 MPa. Because the inserting and matching mode of the first reinforcing steel bar 4 and the second reinforcing steel bar 5 with different diameters is the same as that of the first reinforcing steel bar 4 and the second reinforcing steel bar 5, only the reinforcing steel bar end inserting sleeve 1 with different diameters (apertures) of the first reinforcing steel bar end inserting hole I111 and the second reinforcing steel bar end inserting hole II 112 is selected, and the outer diameter of the whole reinforcing steel bar end inserting sleeve 1 is the same.
Example 2:
referring to fig. 5, the number of the first and second reinforcement end introduction anti-retraction mechanism receiving holes ii 13 and ii 14 is changed to two that are distributed at 180 ° around the circumferential direction of the reinforcement end insertion sleeve 1, and the number of the corresponding first and second reinforcement end introduction anti-retraction mechanisms i 2 and ii 3 is also changed to two, and the rest is the same as that described in embodiment 1.
Example 3:
