Abstract
The invention relates to a screw shear welding nail, which can be used in steel-concrete integrated bridge and high building to increase the adhesive force between steel and concrete. The invention comprises a nail head (1), a nail rod (2), a weld solder (3), and a screw part (4). The surface of nail rod (2) has screw to increase the adhesive force between them. The invention has simple design and wider application in construction area.
Description
Technical field the present invention 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 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.Definite conception of the present invention, method is simple, prevents from effectively shear failure to have improved economic benefit.
Summary of the invention the objective of the invention 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 present invention's 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, utilization of the present invention 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 invention below the description of drawings:
Fig. 1 is a contour structures elevational schematic view one of the present invention; (spiral screw thread)
Fig. 2 is a contour structures elevational schematic view two of the present invention; (lambdoid screw thread)
Fig. 3 is a contour structures elevational schematic view three of the present invention; (two ailhead sizes are identical)
Fig. 4 is a contour structures elevational schematic view four of the present invention; (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 present invention 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 shear welding nail.It is made up of ailhead (1), nail bar (2), welding agent (3), screw thread (4) four parts.Screwed nail bar (2) is processed into the weldering nail, forms screw shear welding nail.It is characterized in that: there is screw thread on nail bar (2) surface, thereby increases it and concrete adhesion stress.
2, nail bar according to claim 1 (2) is characterized in that: nail bar (2) surface is spiral screw thread.
3, nail bar according to claim 1 (2) is characterized in that: nail bar (2) surface is lambdoid screw thread.
4, nail bar according to claim 1 (2) is characterized in that: nail bar (2) surface has increased an ailhead, and its size is identical with the end ailhead.
5, nail bar according to claim 1 (2) is characterized in that: nail bar (2) surface has increased an ailhead, and its size is inequality with the end ailhead.
