Description
Technical field
The present invention relates to a kind of connector, and in particular to a kind of connector fixed suitable for reinforcing bar.
Background technology
Generally, in the construction of the works of armored concrete, steel-bar arrangement is used in concrete to improve intensity.For
It is easy to carry and operation, the reinforcing bar produced has specific length.Therefore, in actual use, reinforcing bar is mostly with phase
The mode of connection uses.
Traditionally, the connected mode of reinforcing bar is the overlapping company tied up behind the end of overlapping two reinforcing bars using tired binding
Connect mode.But in aforesaid way, stitching section only relies upon the adhesive force of reinforcing bar, therefore security is more fragile.
Heated and applying pressure with press-connection machine the gas to be attached to the end of two reinforcing bars with oxy-acetylene flame
In weldering mode, because thermal deformation occurs in stitching section, secondary stress thus occurs, so as to cause stitching section to become than reinforcing bar timber also
It is fragile.
In the regulation of relevant reinforcing bar production, even if applying heat to realize to reinforced concrete structures, reinforcing bar mixes
The purpose that solidifying soil also will not easily collapse, reinforcing bar need to maintain the material character for having similar thermal expansion ratio with concrete, but
It is that in the regulation spliced about South Korea's reinforcing bar, reinforcing bar the splicing more than entitled D29 (diameter 29mm) of reinforcing bar does not allow to make
With folded connecting method, therefore, as described above, crimped by gas or be mechanically connected reinforcing bar, still, aforesaid way carry out to
Reinforcing bar applies the secondary operation of heat or external force, thus, the spelling for the script material character that aforesaid way is possessed for change reinforcing bar
Connect mode.

Brief description of the drawings
Fig. 1 is that (paper is perpendicular to central axis to the connecting-piece structure schematic diagram for being applied to reinforcing bar fixation of the invention
Plane)；
Fig. 2 is Fig. 1 structural representation of the connector for being applied to reinforcing bar fixation at another visual angle.
Embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, it is provided with a screw thread extended along central axis 101 suitable for the connector 100 that reinforcing bar is fixed
Hole 10.It is defined as consolidating suitable for reinforcing bar suitable for full-size of the connector 100 on the direction of central axis 101 that reinforcing bar is fixed
The length L of fixed connector 100；In the plane perpendicular to central axis 101, the connector 100 fixed suitable for reinforcing bar
The outline of projection at least partly coincides with the part on the side of a polygon；At least partly be in the outline projected with
At least a portion on the side of one polygon is overlapping.
Optionally, the polygon can make the even number of sides shape such as hexagon, naturally it is also possible to odd number side shape；More enter one
Step ground, the polygon can make regular polygon.The outline of the projection for being applied to the connector 100 that reinforcing bar is fixed shown in Fig. 1
Partially overlap in the part on the side of a regular hexagon.
Suitable for reinforcing bar fix connector 100 central axis 101 to the distance definition on the side of polygon centered on away from
M；The path of the screwed hole 10 for the connector 100 fixed suitable for reinforcing bar is defined as aperture D.The connector fixed suitable for reinforcing bar
The half of the path of 100 screwed hole is defined as semiaperture R.
Length L and aperture D meet formula L=aD+b；Wherein a is that constant coefficient its span is 1.2 to 4；B is with length
Its span of the corrected parameter of degree unit is -3mm to 3mm.
Length L realizes with aperture D reasonable setting to be saved material and can and enough ensures when being adapted to thicker reinforcing bar,
There is enough length to undertake tangential forces.
With the change of bar gauge, aperture D changes therewith.The length of different size is needed for the reinforcing bar of different size
L。
Further, when aperture D spans are in 12mm to 16mm, a span is 1 to 3；B span
For -3mm to 1mm.Further, when aperture D spans are in 16mm to 20mm, a span is 2 to 3；B value
Scope is -3mm to 1mm.Further, when aperture D spans are in 20mm to 27mm, a span is 2 to 3；B's
Span is -2mm to 2mm.Further, when aperture D spans are in 28mm to 34mm, a span is 2 to 3；
B span is -1mm to 3mm.Further, when aperture D spans are in 35mm to 40mm, a span is
2.5 to 4；B span is -3mm to 3mm.
As aperture D increase is, it is necessary to which bigger length L size avoids steel to undertake sufficiently large tangential forces
Muscle departs from from screwed hole 10.
When aperture D spans are in 12mm to 16mm, for aperture D when smaller, it is necessary to length L compare value hole
Length L needed for the D of footpath is smaller, and its a value is smaller.When aperture D spans are in 16mm to 34mm, taken compared to as aperture D
It is worth scope in 12mm to 16mm, a value to increase.Minimum value increase is reliable to ensure to connect.When aperture, D spans exist
During 35mm to 40mm, a value maximum is more than the maximum of a value when aperture D spans are in 16mm to 34mm.
When aperture D value is 17mm, L span is 44mm to 46mm；When aperture D value is 19mm, L's takes
Value scope is 49mm to 51mm.When aperture D value is 21mm, L span is 54mm to 56mm；Aperture D value is
During 23mm, L span is 59mm to 61mm；When aperture D value is 26mm, L span is 64mm to 66mm.Hole
When footpath D value is 29mm, L span is 69mm to 71mm；When aperture D value is 33mm, L span is
84mm to 86mm.
With aperture D increase, length L increases to ensure reliability therewith.
Specifically, when aperture D value is 17mm, L span is 45mm；When aperture D value is 19mm, L
Span be 50mm；When aperture D value is 21mm, L span is 55mm；When aperture D value is 23mm, L
Span be 60mm；When aperture D value is 26mm, L span is 65mm；When aperture D value is 29mm, L
Span be 70mm；When aperture D value is 33mm, L span is 85mm.
Formed with fillet between two connected faces of the periphery for the connector 100 fixed suitable for reinforcing bar.The radius of fillet
R1 is less than the aperture D of screwed hole 10 half.The radius R1 of fillet is less than or equal to 10mm more than or equal to 5mm.
The periphery for the connector 100 fixed suitable for reinforcing bar is provided with groove 20.The depth H of groove 20 be more than or equal to 1mm and
Less than or equal to 3mm.Prevent from being applied to skidding when the connector that reinforcing bar is fixed is installed, installation is reliable.
As several optional embodiments, such as following table.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
