Abstract
The invention discloses an anti-loose cement nail. The anti-loose cement nail includes a nail cap, a nail rod, and a nail point; the nail cap is arranged on the top of the nail rod and is integrally formed, the lower end of the nail rod integrally forms the nail point; the cement nail is made of 55 number steel; after the cement nail is formed, heat treatment is performed on the cement nail through a net bag type electric furnace, and then the high strength can be achieved; arc anti-rotation grooves (4) are formed in the nail rod in the nailing direction; and the depth of arc grooves of anti-rotation grooves (4) is slightly greater than that of a semicircle, and the arc grooves of anti-rotation grooves (4) have 0.02 mm smooth transitions with the circular surface of the nail rod. The anti-loose cement nail is simple in structure, is large in penetrating power, can effectively prevent loose of cement nails, and improves the safety and reliability of use.
Description
Technical field
The invention belongs to the structural member connection area of nail, the nail being especially applicable to being connected cement components.
Background technology
Cement nail is typically made up of the head of a nail, nail rod and nail tip, the head of a nail is one-body molded in nail rod upper end, nail tip is integrally made in nail rod lower end, cement nail is mainly used in building trade, when ordinary cement nail injects cement wall surface by pneumatic nail gun, due to composition and the difference of ratio of cement, often there is nail phenomenon loosely, qualitative problems of construction in various degree can be caused.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, thering is provided a kind of prevents the cement loosened from dissipating nail, this pin structure is simple, penetration power is strong, effectively prevent loosening of cement nail, the present invention solves it and technical problem is that and take techniques below scheme to realize: a kind of prevent the cement loosened from dissipating nail, by the head of a nail, nail rod and nail tip are constituted, the head of a nail is one-body molded in nail rod upper end, nail tip is integrally made in nail rod lower end, arc anti-rotation groove is had in the direction that hammers into of nail rod, the arcuate groove degree of depth of anti-rotation groove is slightly larger than the degree of depth of semicircle, and the disc of its arcuate groove and nail rod has the rounding off of 0.02 millimeter, No. 55 steel of material selection, after nailing molding, net-bag type electric furnace heat treatment is to reach high intensity.
Advantages of the present invention and good effect be: this pin structure is simple, penetration power strong, especially can effectively prevent loosening of cement nail, improve the safety and reliability of use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is the sectional view of nail rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described: a kind of cement preventing from loosening dissipates to be followed closely, as depicted in figs. 1 and 2, by the head of a nail (1), nail rod (2) and nail tip (3) are constituted, the head of a nail (1) is one-body molded in nail rod (2) upper end, nail tip (3) is integrally made in nail rod (2) lower end, No. 55 steel of material selection, after nailing molding, net-bag type electric furnace heat treatment is to reach high intensity, when cement nail penetrates people's metope by nailing gun, the direction that hammers into of nail rod has arc anti-rotation groove (4) can effectively prevent cement from dissipating nail loose or dislocation, the arcuate groove degree of depth of anti-rotation groove (4) is slightly larger than the degree of depth of semicircle, and the disc of the arcuate groove of anti-rotation groove (4) and nail rod (2) has the rounding off of 0.02 millimeter, the most advantageously enter metope in cement nail.
It should be noted that; anti-rotation groove of the present invention (4) embodiment is illustrative; rather than it is determinate; the anti-rotation mode of every other analogous shape drawn on nail rod (2) direction according to technical scheme by those skilled in the art, also belongs to the scope of protection of the invention.
Claims (3)
1. the cement preventing from loosening dissipates nail, it is made up of the head of a nail (1), nail rod (2) and nail tip (3), the head of a nail (1) is one-body molded in nail rod (2) upper end, nail tip (3) is integrally made in nail rod (2) lower end, it is characterized in that: No. 55 steel of material selection, after nailing molding, net-bag type electric furnace heat treatment is to reach high intensity, and there is arc anti-rotation groove (4) in the direction that hammers into of nail rod.
A kind of cement preventing from loosening the most according to claim 1 dissipates to be followed closely, it is characterised in that: the arcuate groove degree of depth of anti-rotation groove (4) is slightly larger than the degree of depth of semicircle.
A kind of cement preventing from loosening the most according to claim 1 dissipates to be followed closely, it is characterised in that: the disc of the arcuate groove of anti-rotation groove (4) and nail rod (2) has the rounding off of 0.02 millimeter.
