Description
Technical field
The present invention relates to a kind of rebar connector, and in particular to a kind of reinforced bar jointing sleeve.
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.
The content of the invention
High it is an object of the invention to provide a kind of reliability to solve the deficiencies in the prior art, reinforcing bar splices efficiently
Reinforced bar jointing sleeve.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
A kind of reinforced bar jointing sleeve, provided with a screwed hole, screwed hole definition has a central axis, and screwed hole is along central shaft

By setting rational size, realization can either ensure higher connection reliability, turn avoid rebar connector
The waste of material, and the use of the oversized reinforcing bar for influenceing connection of rebar connector.
Brief description of the drawings
Fig. 1 is the reinforced bar jointing sleeve structural representation of the present invention (paper is the plane perpendicular to central axis)；
Fig. 2 is the structural representation that Fig. 1 bar connecting is enclosed on 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, reinforced bar jointing sleeve 100 is provided with a screwed hole 10 extended along central axis 101.Reinforcing bar connects
Full-size of the female connector 100 on the direction of central axis 101 is defined as the length L of reinforced bar jointing sleeve 100；Perpendicular to central shaft
In the plane of line 101, the outline of the projection of reinforced bar jointing sleeve 100 at least partly coincides with one of the side of a polygon
Point；It with least a portion on the side of a polygon is overlapping to be at least partly in the outline projected.
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 of reinforced bar jointing sleeve 100 shown in Fig. 1 partially overlaps in one
The part on the side of individual regular hexagon.
Away from M centered on the central axis 101 of reinforced bar jointing sleeve 100 to the distance definition on the side of polygon；Reinforced bar jointing sleeve
The path of 100 screwed hole 10 is defined as aperture D.The half of the path of the screwed hole of reinforced bar jointing sleeve 100 is defined as half
Aperture R.
Centre-to-centre spacing M, aperture D and semiaperture R meet formula M=nD+R+m, wherein, centre-to-centre spacing M, aperture D and semiaperture R's
Unit is millimeter, and n is that constant coefficient its span is 0.1 to 0.5；M is its value model of the corrected parameter with long measure
Enclose for -0.9mm to 0.9mm.
Centre-to-centre spacing M, aperture D and semiaperture R rational design and can ensure for relative while material is saved
During thicker reinforcing bar, it can be held using suitable wall thickness and preferably ensure bonding strength.
With the change of rebar sizes, aperture D changes therewith.The aperture of different size is needed for the reinforcing bar of different size
D。
Further, for aperture D spans in 12mm to 16mm, n span is 0.1 to 0.2；M value model
Enclose for -0.5mm to -0.1mm.For aperture D spans in 16mm to 20mm, n span is 0.2 to 0.3；M value
Scope is -0.6mm to -0.2mm.For aperture D spans in 20mm to 27mm, n span is 0.2 to 0.3；M's takes
It is -0.8mm to -0.3mm to be worth scope.For aperture D spans in 28mm to 34mm, n span is 0.2 to 0.3；M's
Span is -0.9mm to -0.4mm.For aperture D spans in 35mm to 40mm, n span is 0.4 to 0.5；m
Span be -0.5mm to -0.1mm.
Centre-to-centre spacing M and semiaperture R difference are defined as wall spacing；As aperture D increase is, it is necessary to suitable wall spacing
To ensure bonding strength.Aperture D spans in 12mm to 16mm, for aperture D it is smaller when, it is necessary to which centre-to-centre spacing M compares it
His size is smaller, and its n value is smaller.Aperture D spans are in 16mm to 34mm, compared to aperture D spans in 12mm
To 16mm, n value increases.For aperture D spans in 35mm to 40mm, n value is more than aperture D spans in 16mm
To the value of n during 34mm.
Further, when aperture D value is 17mm, the span of wall spacing is 4mm to 5mm；When taking for aperture D
Be worth for 19mm when, the span of wall spacing is 5mm to 6mm.Further, when aperture D value is 21mm, wall spacing
Span is 5.5mm to 6.5mm；When aperture D value is 23mm, the span of wall spacing is 6mm to 7mm；Work as hole
When footpath D value is 26mm, the span of wall spacing is 6.5mm to 7.5mm.Further, when aperture D value is 29mm
When, the span of wall spacing is 7.5mm to 8.5mm；When aperture D value is 33mm, the span of wall spacing is
8.5mm to 9.5mm.Further, when aperture D value is 13mm, the span of wall spacing is 1mm to 3mm；Work as aperture
When D value is 15mm, the span of wall spacing is 1.5mm to 3mm；When aperture D value is 36mm, wall spacing takes
Value scope is 11mm to 13mm；When aperture D value is 39mm, the span of wall spacing is 18mm to 20mm.
With aperture D increase, the value of wall spacing is incrementally increased to ensure reliability.The periphery of reinforced bar jointing sleeve 100
Formed with fillet between two connected faces.The semiaperture R1 of fillet is less than the aperture D of screwed hole 10 half.Fillet
Semiaperture R1 is less than or equal to 10mm more than or equal to 5mm.
The periphery of reinforced bar jointing sleeve 100 is provided with groove 20.The depth H of groove 20 is more than or equal to 1mm and is less than or equal to 3mm.
Prevent from skidding when reinforced bar jointing sleeve from installing, installation is reliable.
