Description
Technical Field
The utility model belongs to the technical field of the hardware fastening spare, concretely relates to use very convenient can improve rag bolt of perpendicular installation accuracy.
Background
The foundation bolt is a screw rod piece for fastening equipment and the like on a concrete foundation, is generally used for railways, highways, power enterprises, light poles, factories, mines, bridges, tower cranes, steel structures and other infrastructures, and has high strength; one end of each foundation bolt is provided with threads so as to be convenient to fasten with equipment, and the other end of each foundation bolt is L-shaped, is bent in a hook shape or is welded with a square plate so as to increase the friction force between the foundation bolt and concrete and prevent the bolt from being pulled out and damaged; the foundation bolt is required to be vertical to the ground without inclination when being installed; if the installation is not vertical, errors are generated on the installation coordinates of the bolts certainly, certain difficulty is caused on the installation, and the bearing capacity of the bolts is reduced because the bolts are not vertical; for example, the equipment connected with the anchor bolt generally has a higher height, for example, a light pole, the offset perpendicularity is 1 degree in the anchor bolt laying process, so that the offset of the light pole connected with the light pole at the top can be amplified by several times or even dozens of hundreds of times, which is not beneficial to prolonging the service life of the equipment such as the light pole and the like, and is easy to cause safety accidents. However, the existing anchor bolts do not have a vertical angle measuring function, under many environments, professional surveying and mapping personnel are often required to measure the anchor bolts by using professional horizontal instruments, time and labor are wasted in installation and laying of the anchor bolts, the anchor bolts are often kept horizontal by means of naked eyes of workers in the environment lacking of measuring instruments, and therefore equipment cannot be installed or the service lives of the installed equipment and bolts are shortened and safety accidents occur.
Disclosure of Invention
The utility model discloses an it is not enough above solving, provide one kind and improve the perpendicular installation accuracy person of rag bolt and observe the straightness that hangs down of rag bolt at any time, carry out angular adjustment's rag bolt at any time.
The utility model provides a, an improve rag bolt of perpendicular installation accuracy, its characterized in that: the anchor rod is arranged on the lower end part of the bolt rod, the upper end part of the bolt rod is provided with an external thread, and the upper end part of the bolt rod forms a threaded rod; the threaded rod is characterized in that a head groove is formed in the surface of the head of the threaded rod, and a head level bubble is installed in the head groove.
The head level bubble is installed in the head groove in an interference fit installation mode.
The outer wall of the head leveling bubble is composed of a plastic shell or a metal shell, the plastic shell or the metal shell is enclosed to form a cavity, colored liquid is filled in the cavity, air bubbles float in the colored liquid, and the upper end face of the cavity is hermetically provided with a transparent mirror surface body.
The surface of the transparent mirror surface is provided with scale marks and a circular line arranged in the center, and the air bubbles are positioned in the center of the circular line in a horizontal state.
The transparent mirror surface body is made of glass or organic plastic.
The utility model discloses beneficial effect: compared with the prior art, the utility model discloses a be provided with the air level at the threaded rod head, can carry out vertical angle correction to rag bolt in real time in the installation, solved rag bolt greatly and measured laying installation reuse spirit level after accomplishing, need dismantle again the vexation again if the angle is incorrect.

Fig. 2 is an enlarged schematic view of a point a in fig. 1.
Fig. 3 is a schematic cross-sectional structure diagram of the leveling bubble of the present invention.
Fig. 4 is a front view of the vial of the present invention.
1. A head vial; 2. a threaded rod; 3. a bolt shank; 4. a ground foot hook; 101. an outer wall; 102. air bubbles; 103. a transparent specular body; 104. a colored liquid; 105. a circular line; 106. scale lines are marked.
Detailed Description
As shown in fig. 1 to 2, an anchor bolt for improving vertical installation accuracy includes a bolt shaft 3 and an anchor hook 4 integrally provided with the bolt shaft 3, the anchor hook 4 being provided at a lower end portion of the bolt shaft 3, an upper end portion of the bolt shaft 3 being provided with an external thread, and an upper end portion thereof being formed as a threaded shaft 2; the surface of the head of the threaded rod 2 is provided with a head groove, and a head level bubble 1 is arranged in the head groove.
As shown in fig. 3, the outer wall 101 of the head vial 1 is composed of a plastic shell or a metal shell, the plastic shell or the metal shell encloses a cavity, a colored liquid 104 is filled in the cavity, an air bubble 102 floats in the colored liquid 104, and a transparent mirror surface 103 is hermetically arranged on the upper end surface of the cavity to facilitate observation of the floating direction of the air bubble 102 in the colored liquid 104.
As shown in fig. 4, the transparent mirror surface 103 is provided with a graduation mark 106 and a circular line 105 at the center, and the air bubble 102 is located in the center of the circular line 105 in a horizontal state.
The transparent mirror surface body 103 is made of glass or organic plastic.
During the laying of the foundation bolts, the position deviation of the air bubbles 102 in the level bubble only needs to be observed in real time, if the air bubbles 102 are located at the center of the circular line 105 of the level bubble, the foundation bolts can be judged to be in the vertical position, if the air bubbles 102 are not located at the center of the circular line 105 of the level bubble, the foundation bolts can be not located in the vertical position, and the foundation bolts can be adjusted in real time according to the deviation of the air bubbles 102.
The utility model discloses simple structure, reasonable in design, it is very convenient to use.
The above description is only a preferred example of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
