Abstract
The invention discloses a spine-free reinforcing steel bar with interrupted spiral ribs. The spine-free reinforcing steel bar comprises a spine-free central body, and a plurality of spiral ribs which are interruptedly screwed into the spine-free central body; the spiral ribs are ridge-shaped bumps; and the range of the included angle between two upper surfaces of each spiral rib is 50 to 150 degrees, and the included angle between one upper surface of the plurality of interrupted spiral ribs and the spine-free central body in an axial direction is greater than 50 degrees. Two spine-free reinforcing steel bars with the interrupted spiral ribs can be connected through a reinforcing steel bar connector with corresponding spiral threads; on one hand, other connecting tools, such as steel wires, welders and the like are not needed, and the connection speed and labor efficiency are improved; on the other hand, the connection does not change any structure and appearance of the original reinforcing steel bar, so that the mechanical strength of the reinforcing steel bar is not influenced.
Description
Technical field
The present invention relates to a kind of no ridge reinforcing bar, especially, relate to a kind of no ridge reinforcing bar that has interrupted spiral ribs.
Background technology
In the prior art, following several method when being connected, reinforcing bar is arranged generally during construction.The one, steel wire lashing method, this kind method need use steel wire that reinforcing bar is carried out high-intensity colligation.If make steel wire fracture easily but run into high-intensity earthquake or other contingencies, thereby steel wire performs practically no function.Another reinforcing bar connection method is the mechanical connection method, just is to use reinforcing bar connector to connect, but because reinforcing bar has ridge, thereby and reinforcing bar reduce after through section behind the car tooth and make the weakened of reinforcing bar.Next is exactly a welding, and welding needs high-quality solder technology, and makes total cost raise because field Welding need expend other manpower and materials cost.Therefore the connecting method for reinforcing bars of using always in the prior art all has defective separately.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, disclose a kind of novel reinforcing bar, this kind reinforcing bar can not use the connecting method for reinforcing bars of prior art.And use the screw connector that adapts with new reinforcing steel bar just two reinforcing bars securely can be linked together.
The invention discloses a kind of no ridge reinforcing bar that has interrupted spiral ribs, comprising: no ridge centerbody; Several spiral ribs, its interrupted spiral is on described no ridge centerbody, described spiral ribs is a ridge shape projection, the one-tenth angular region of two upper surfaces of described spiral ribs is the 50-150 degree, and one of them upper surface of described interrupted several spiral ribs become the angle with the axial direction of described no ridge centerbody be to spend greater than 50.
Preferably, a kind of reinforcing bar that has spiral ribs of the present invention, the one-tenth angular region on two surfaces of described spiral ribs is the 60-120 degree.
Preferably, a kind of reinforcing bar that has spiral ribs of the present invention, it is the 60-150 degree that one of them upper surface of described spiral ribs becomes the angle with the axial direction of described no ridge centerbody.
Preferably, a kind of reinforcing bar that has spiral ribs of the present invention, the hand of spiral of described several spiral ribs is left-hand.
Preferably, a kind of reinforcing bar that has spiral ribs of the present invention, the hand of spiral of described several spiral ribs is dextrad.
The invention has the beneficial effects as follows: the no ridge reinforcing bar that has interrupted spiral ribs of the present invention can couple together two reinforcing bars by the reinforcing bar connector with corresponding screw, on the one hand need not be again by means of other fastening means, for example steel wire and soldering apparatus etc., improve connection speed, improved efficiency; On the other hand because this kind connection does not change any structure and the outward appearance of former reinforcing bar, thus to the mechanical strength of reinforcing bar without any influence.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing, can implement according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, the no ridge reinforcing bar that has interrupted spiral ribs of the present invention comprises: no ridge centerbody 1; Several spiral ribs 6, its interrupted spiral is on described no ridge centerbody 1, described spiral ribs 6 is a ridge shape projection, two upper surfaces 4 of described spiral ribs are the 50-150 degree with 5 the angular region that becomes, and one of them upper surface of described interrupted several spiral ribs 6 become the angle with the axial direction of 4 described no ridge centerbodies be to spend greater than 50.
The reinforcing bar that has spiral ribs of the present invention, two surfaces 4 of described spiral ribs 6 with 5 become preferably 60-120 degree of angular region.
The reinforcing bar that has spiral ribs of the present invention, one of them upper surface 4 of described spiral ribs 6 becomes the angle to be preferably the 60-150 degree with the axial direction of described no ridge centerbody 1.
The reinforcing bar that has spiral ribs of the present invention, the hand of spiral of described several spiral ribs 6 are left-hand or dextrad.
As shown in Figure 1, when the reinforcing bar that has a spiral ribs with two couples together, need to use and the reinforcing bar connector that has interrupted screw 2 that the reinforcing bar that has interrupted spiral ribs of the present invention adapts couples together two reinforcing bars.If think further two reinforcing bars of this kind to be fastenedly connected, then can be in the both sides of reinforcing bar centerbody 1 additional fasteners 3.Soldering apparatus and other extra equipment so, then do not need to use other annex such as steel wire, just can tighten together two reinforcing bars.Thereby, reduced construction cost.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in manual and the embodiment, it can be applied to various suitable the field of the invention fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the present invention is not limited to specific details and illustrates here and describe.
