Description
Technical field
The utility model is related to a kind of reinforcing bar, more particularly to a kind of finish rolling deformed bar being chiefly used in bridge structure.
Background technology
Screw-thread steel is being commonly called as hot rolled ribbed bars, and screw-thread steel is surface reinforcing bar with ribbing, also known as Ribbed Bar, usual band
There are 2 longitudinal ribs and along its length equally distributed cross rib, the shape of cross rib is spiral shape, herringbone, 3 kinds of crescent, with public affairs
The millimeter of diameter is claimed to indicate that the nominal diameter of Ribbed Bar is equivalent to the nominal diameter of the equal plain bar in cross section, steel
The nominal diameter of muscle is 8-50 millimeters, and Ribbed Bar is primarily subjected to tensile stress in concrete, Ribbed Bar due to rib effect,
There is larger cementitiousness with concrete, thus can preferably bear the effect of external force, Ribbed Bar is widely used in various buildings
Structure, particularly large size, heavy type, light thin wall and high building structure, spiral (also referred to as finish rolling spiral shell for prestressed concrete
Line reinforcing bar) it is that externally threaded major diameter, high intensity, the straight steel bar of high dimensional accuracy are rolled on whole reinforcing bar, which exists
It is all screwed at arbitrary section and threaded nut is attached or screwed on female connector is anchored, finish rolling screw thread
Reinforcing bar is widely used in the continuous beam in large hydraulic engineering, industry and civil buildings and large-scale frame structure, and highway, railway are big
The engineerings such as middle bridge beam, nuclear power station and earth anchor, it has connection, anchoring easy, and adhesion strength is strong, and stretch-draw anchor is safe and reliable, applies
The advantages that work facilitates, and reinforcing bar is saved, reduce component area and weight.
On the basis of the technical conditions of existing spiral, still deposited in the range used and structure of reinforcing bar
Many insufficient, the inside bond strength of the support strength of spiral and reinforcing bar used in most of bridge is still not
It is enough, make the load bearing stength of its bridge by certain limitation.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides one kind and being chiefly used in bridge structure
Finish rolling deformed bar, which is changed traditional screw thread steel construction, is used using Bougainvillea spectabilis flower type structure, greatly
The strong internal intensity of spiral, improves stress intensity, while the helicitic texture can reinforce the internal frictional strength cohered,
Make inside it more securely.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of finish rolling deformed bar being chiefly used in bridge structure of the utility model, including reinforcing bar ontology, the reinforcing bar ontology
Surface be respectively arranged with and rotate in the forward direction screw thread and reversely rotate screw thread, the both ends of the reinforcing bar ontology are both provided with thread,
The end set of the thread is locked end, and the groove of the reinforcing bar ontology is provided with connection end tooth, the forward direction
Rotation screw thread and the both ends for reversely rotating screw thread are both provided with protruding block.
It is described to rotate in the forward direction screw thread and reversely rotate screw thread in reinforcing bar as a kind of optimal technical scheme of the utility model
Body upper surface is arranged in a crossed manner.
As a kind of optimal technical scheme of the utility model, the reinforcing bar ontology is that Bougainvillea spectabilis is flower-shaped.
Compared with prior art, the beneficial effects of the utility model are as follows：
The utility model is a kind of finish rolling deformed bar being chiefly used in bridge structure, can effectively improve spiral
Use scope and convenience, the reinforcing bar are changed traditional screw thread steel construction, are used using Bougainvillea spectabilis flower type structure, greatly
The big internal intensity for strengthening spiral improves stress intensity, while the helicitic texture can reinforce the internal friction cohered
Intensity makes inside it more securely.

Embodiment 1
As shown in Figs. 1-2, the utility model provides a kind of finish rolling deformed bar being chiefly used in bridge structure, including reinforcing bar sheet
Body 1, the surface of reinforcing bar ontology 1, which is respectively arranged with, to be rotated in the forward direction screw thread 2 and reversely rotates screw thread 2, and the both ends of reinforcing bar ontology 1 are all provided with
It is equipped with thread 4, the end set of thread 4 is locked end 5, and the groove of reinforcing bar ontology 1 is provided with connection end tooth 6,
The both ends for rotating in the forward direction screw thread 2 and reverse rotation screw thread 2 are both provided with protruding block 7.
Further, it rotates in the forward direction screw thread 2 and reverse rotation screw thread 2 is arranged in a crossed manner in 1 upper surface of reinforcing bar ontology, by setting
Set rotate in the forward direction screw thread 2 with reversely rotate screw thread 2 can effectively stiffener and concrete inside bond strength, promoted reinforcing bar
Use scope.
Reinforcing bar ontology 1 is that Bougainvillea spectabilis is flower-shaped, is designed to the flower-shaped bending resistance for promoting reinforcing bar of Bougainvillea spectabilis, promotes reinforcing bar
Use scope.
Specifically, the utility model is when in use, screw thread 2 and reverse rotation screw thread 2 are rotated in the forward direction by setting
Can effectively stiffener and concrete inside bond strength, promote the use scope of reinforcing bar, be designed to that Bougainvillea spectabilis is flower-shaped and carry
The bending resistance for rising reinforcing bar, promotes the use scope of reinforcing bar, can enhance internal friction by being provided at both ends with thread 4
Power keeps connection more secured, while the end 5 that is locked being arranged can fasten both ends, prevent sliding phenomenon, practicability
By force.
The reinforcing bar can effectively improve the use scope and convenience of spiral, change traditional screw-thread steel knot
Structure is used using Bougainvillea spectabilis flower type structure, has greatly reinforced the internal intensity of spiral, improves stress intensity, together
When the helicitic texture can reinforce the internal frictional strength cohered, make inside it more securely.
