Abstract
The utility model discloses a ground nail, which comprises a floor device and a fixing device, the single direction or a plurality of directions of the upper surface of the floor device is stuck with reflecting lamp sheets, the fixing device comprises a screw thread segment arranged under the floor device and expansion nails screwed on the screw thread segment, the side wall of the expansion nails is provided with a plurality of hook grooves and at least one hook groove is provided with a hook part which is turned aside outward. After cement or bitumen is poured, the cement or the bitumen is coated at the hook grooves of the expansive nails and the circumference of the hook part, the gripping and supporting strength of the whole ground nail is increased by the hook grooves and the ground nail is prevented from emerging longitudinally from the inner part of a floor. Because the hook part is turned aside outward, axial block force is formed after the hook part is matched with the cement or the bitumen, thereby, the axial rotation of a buried ground nail can be prevented.
Description
Technical field
The utility model relates to a kind of ground nail.
Background technology
At present, be provided with the reflector lamp sheet that is used to indicate the path usually on speedway or other ordinary road, this reflector lamp sheet nails on with being arranged at, and ground nail then is embedded with on the road.Generally in the both sides of road, just bury such ground nail that has the reflector lamp sheet underground every a segment distance, when arrived night, this reflector lamp sheet just can reflect the light of street lamp or car light, thereby the path of road is marked.
The structure of above-mentioned ground nail usually as shown in Figure 1, it comprise ground installation 1 ' and the fastening devices 2 of column ', the reflector lamp sheet 3 that on the single direction of ground installation 1 ' upper surface or a plurality of direction, is sticked '.During use, fastening devices 2 ' circumfusion on cement or pitch, ground installation 1 ' then expose to ground can be embedded in ground nail on the ground like this.Yet, the fastening devices 2 of this known ground nail ' owing to be a column, it is embedded in cement or asphalt floor after, often the automobile because of high-speed motion rotates it, thereby the direction of reflector lamp sheet 3 is changed, and do not reach marked effect, sometimes ground nail even wholely break away from from ground.Though known ground nail fixing device 2 ' cylinder be provided with longitudinally reinforcing rib 21 ', its can increase fastening devices 2 ' with the grasping force on ground, to prevent its relative ground rotation, but because structural limitations, this reinforcing rib 21 ' to grasp effect unsatisfactory, and can't prevent that whole ground nail vertically breaks away from from ground.
The utility model content
The purpose of this utility model is to provide a kind of ground nail, and it can increase the grasping force of ground nail, vertically breaks away from from ground to prevent it, and can prevent that ground nail from rotating arbitrarily.
For achieving the above object, technical solution of the present utility model is: a kind of ground nail, comprise ground installation and fastening devices, and the reflector lamp sheet is sticked on the single direction of ground installation upper surface or a plurality of direction; Described fastening devices comprises thread segment and the expandable nail of spiral shell on this thread segment of being located at the ground installation below, and this expandable nail sidewall is provided with some hook grooves, and at least one hook groove is provided with the hook portion of outwards bypassing.
The central authorities of described ground installation are provided with a through hole, and a long spiro nail penetrates from this through hole top, and the elevate above the soil below of device of the thread segment of this long spiro nail forms the thread segment of fastening devices.
Have vertical groove on the sidewall of described expandable nail, described hook groove is located on the wall of vertical groove both sides.
The soffit outside of described ground installation is provided with the spline pin.
After adopting such scheme, because fastening devices of the present utility model is provided with expandable nail, after cement or pitch perfusion, to be coated on around the hook groove and hook portion of this expandable nail, the hook groove will increase the dynamics that grasps of whole ground nail, prevent that ground nail from vertically deviating from ground, and hook portion is owing to outwards bypass, its with will form the axial power of keeping out after cement or pitch cooperate, thereby can prevent the ground nail axial rotation imbedded.
Description of drawings
Fig. 1 is the structural representation of known ground nail;
Fig. 2 is a three-dimensional exploded view of the present utility model;
Fig. 3 is a three-dimensional combination figure of the present utility model;
Fig. 4 is the three-dimensional combination figure of looking up of the present utility model.
The specific embodiment
Shown in Fig. 2,3,4, ground nail described in the utility model comprises ground installation 1 and fastening devices 2.Wherein,
Described fastening devices 2 comprises a long spiro nail 21 and an expandable nail 22, and this long spiro nail 21 penetrates from the through hole 11 of ground installation 1, and its head of screw is butted on the counterbore 12, then the elevate above the soil below of device 1 of its thread segment; Described expandable nail 22 is similar to the expandable nail of setscrew, which is provided with hole 221, but its spiral shell is located on the long spiro nail 21, its sidewall has vertical groove 222 makes it have radially elasticity, and vertically the wall of groove 222 both sides is provided with some hook grooves 223, and a pair of therein hook groove 223 is provided with the hook portion 224 of outwards bypassing.
In addition, above the counterbore 12 of described ground installation 1, also can seal again and establish a cover plate 14,, ground nail be scooped away from ground, can prevent that also dirt from entering in the counterbore 12 to have prevented the people in order to this counterbore 12 of shutoff.
The utility model in use, the through hole 11 of long spiro nail 21 from ground installation 1 passed, seal up cover plate 14 again, then with expandable nail 22 spiral shells on long spiro nail 21, cement or pitch on the circumfusion of fastening devices 2 afterwards, the upper surface of ground installation 1 then exposes to outside the ground, ground nail can be embedded on the ground like this.
From above structure as can be known, the utility model is owing to be provided with expandable nail 22, and after cement or pitch perfusion, its vertical groove 222 formed radial elastic power will make it inwardly compress long spiro nail 21, thereby can prevent that both break away from; In addition, cement or pitch will be coated on around the hook groove 223 and hook portion 224 of expandable nail 22, hook groove 223 will increase the dynamics that grasps of whole ground nail, prevent that ground nail from vertically deviating from ground, and hook portion 224 is owing to outwards bypass, its with will form the axial power of keeping out after cement or pitch cooperate, thereby can prevent the ground nail axial rotation imbedded, in addition, the spline pin 13 of ground installation 1 soffit has the effect of axially keeping out equally, and prevents that ground nail from axially rotating.
Need to prove, the utility model is an one-body molded body of rod below ground installation 1 directly, thread segment is set on the body of rod again, and then expandable nail 22 is arranged on this thread segment, this kind embodiment can reach purpose described in the utility model and effect equally.
