Abstract
The utility model discloses a cement anchoring nail which has simple structure, reliable connection, easy manufacture and convenient use and is not easy to loose. The cement anchoring nail comprises a screw rod with a conical front end, wherein screw threads are manufactured on the screw rod. The cement anchoring nail is characterized in that the tail end of the screw rod is connected with a cylindrical head, and a prismatic lug boss or a prismatic pit which is used for rotating the screw rod is manufactured on the cylindrical head. The utility model has the advantages that because the cylindrical head is obviously larger than the screw rod, the connection is reliable; when the cement anchoring nail is disassembled in the original hole, the connecting piece is not remained in the original hole, and the surface of the original hole is smooth; and if the cement anchoring nail is used at the original hole again, another large cement anchoring nail can be replaced to use. The cement anchoring nail can be widely used for connecting the fixing bodies of cement, brick walls, and the like and has the advantages of reliable connection, attractive appearance and position reuse of the original hole.
Description
Technical field
The utility model relates to a kind of screw that is used for fixing on cement components, relates in particular to the cement anchor nail.
Background technique
Common EXPANSION ANCHOR BOLTS is made up of bolt, expand tube, plain washer, spring pad and the hexagon nut of major part.During use, get out earlier the hole of corresponding size with electric impact drill (hammer) on fixed body, in bolt, the expand tube load hole, screw nut again, the beneath major part of bolt is just the expand tube spreading, makes that swelling becomes one between bolt, expand tube, assembling set and the fixed body.The shortcoming of this EXPANSION ANCHOR BOLTS is that exposed parts is not bright and clean, still stays on the fixed body at bolt after the dismounting and expand tube, can not reinstall fixed block again with the fixed position of overexpansion bolt originally, and the bolt exposed surface is arranged.
Summary of the invention
The purpose of this utility model is to solve the shortcoming that exists in the existing product, provides a kind of cement anchor simple in structure, that connection is reliable, difficult loosening, easy to manufacture, easy to use to follow closely.
In order to reach above-mentioned requirements, the utility model is achieved in that it includes the conical screw rod of front end, is shaped on screw thread on the screw rod, it is characterized in that being connected with socket cap at the screw rod tail end, is shaped on prismatic boss or the pit used for rotary screw on socket cap.Described prismatic boss is six prisms.Described pit is the pit of interior hex slot or the pit of plum blossom groove.Be shaped on locking tooth in the bottom surface of described socket cap.On the screw rod outer surface, be shaped on 2～3 leg-of-mutton cutting slots.
Follow closely according to the cement anchor that such scheme is made, during use, on fixed body, get out the hole of corresponding size earlier with electric impact drill (hammer), again the cement anchor nail is placed in the hole, with electric drill the cement anchor nail is screwed in the hole, utilizes the screw thread on the screw rod that the cement anchor nail is connected with fixed body.Its advantage is because socket cap obviously greater than screw rod, connects reliably, after the cement anchor nail removes in the foramen primum, does not linger on fitting in the hole, and hole surface is smooth, even need utilize in former hole site, the cement anchor nail that can use bigger specification instead gets final product again.This cement anchor nail can be widely used as and being connected of fixed bodies such as cement, brick wall, have connect reliably, surface aesthetic, to the recycling advantage in former hole site.
