Abstract
The utility model relates to a kind of screw-threaded shear nail that can increase adhesion stress.More particularly, relate to a kind of steel-concrete combined bridge, highrise building etc. of being particularly suitable for, for steel and concrete increase measure and the method that adhesion stress is taked.Comprise ailhead (1), nail bar (2), welding agent (3), screw thread (4) four parts composition.There is screw thread on nail bar (2) surface, thereby increases it and concrete adhesion stress.This method simplicity of design, easy construction are with a wide range of applications in building trade, construction of road and bridge field.
Description
Technical field the utility model relates to a kind of screw shear welding nail.More particularly, relate to a kind of steel-concrete combined bridge, highrise building etc. of being particularly suitable for, for steel and concrete increase measure and the method that adhesion stress is taked.
Background technology in the prior art, usually adopt weldering nail Transfer of Shear in the steel-concrete combined structure, the relevant report that does not have screw shear welding nail temporarily, application number 97200102.6 disclosed " the two-way hollow big plate of steel concrete shear connector " is made up of the shear connector of last rib, following rib and rib connection up and down.In addition, common shear welding stud can only solve by increasing weldering nail density because root power transmission effect is relatively poor, and is uneconomical.The utility model definite conception, method is simple, prevents from effectively shear failure to have improved economic benefit.
The summary of the invention the purpose of this utility model is to utilize the interlocking of screw thread, can increase the frictional resistance between steel and the concrete.Simplicity of design, easy construction, be widely used.
In order to achieve the above object, the utility model provides following technical scheme: the nail bar (2) that will be threaded (4) is processed into the have ailhead screw of (1), lays welding agent (3) in its bottom, promptly forms screw shear welding nail.
The utility model technical scheme preferably is: nail bar (2) is the circular section steel pole, highly is 5～30 centimetres, to give full play to mechanical properties of materials.
Compared with prior art, the utility model utilization utilizes the interlocking of screw thread, can increase the frictional resistance between steel and the concrete, prevents shear failure, has improved economic benefit.Have broad application prospects in building trade especially bridge, highrise building field.
Be description of drawings of the present utility model below the description of drawings:
Fig. 1 is a contour structures elevational schematic view one of the present utility model; (spiral screw thread)
Fig. 2 is a contour structures elevational schematic view two of the present utility model; (lambdoid screw thread)
Fig. 3 is a contour structures elevational schematic view three of the present utility model; (two ailhead sizes are identical)
Fig. 4 is a contour structures elevational schematic view four of the present utility model; (two ailhead sizes are inequality)
Among Fig. 1～Fig. 4, (1) is that ailhead, (2) are that nail bar, (3) are that welding agent, (4) are screw threads.
By specific embodiment the utility model is carried out more detailed description below the specific embodiment:
With reference to Fig. 1,2,3 and 4, the nail bar (2) that will be threaded (4) earlier is processed into the have ailhead screw of (1), lays welding agent (3) in its bottom, promptly forms screw shear welding nail.Simultaneously, also can nail bar (2) surface of common shear welding stud be processed, form shape of threads, also form screw shear welding nail.
Claims (5)
1, a kind of screw-threaded shear nail, it is made up of ailhead (1), nail bar (2), welding agent (3), screw thread (4) four parts, the nail bar (2) that will be threaded (4) is processed into the weldering nail, formation screw-threaded shear nail, it is characterized in that: there is screw thread (4) on nail bar (2) surface, thereby increases it and concrete adhesion stress.
2, screw-threaded shear nail according to claim 1 is characterized in that: nail bar (2) surface is spiral screw thread (4).
3, screw-threaded shear nail according to claim 1 is characterized in that: nail bar (2) surface is lambdoid screw thread (4).
4, screw-threaded shear nail according to claim 1 is characterized in that: nail bar (2) surface has increased an ailhead (1), and its size is identical with end ailhead (1).
5, screw-threaded shear nail according to claim 1 is characterized in that: nail bar (2) surface has increased an ailhead (1), and its size is inequality with end ailhead (1).
