Description

Technical Field

[0001] The utility model belongs to the technical field of anchor bolts, in particular to a reinforced anchor bolt. Background Art

[0002] Anchor bolts are screw rods used to fasten equipment to concrete foundations. The part of this bolt buried in concrete is J-shaped or L-shaped, and has strong stability after pouring. It is widely used in infrastructure such as railways, highways, power companies, factories, mines, bridges, tower cranes, large-span steel structures and large buildings to fasten equipment and ensure its stability.

[0003] First of all, the bending part of the traditional J-shaped and L-shaped anchor bolts can only face one direction, and the gripping force needs to be improved. There are also some bolts on the market that have multiple bending parts welded along the circumference of the bottom of the bolt, which will greatly increase the occupied space compared to the J-shaped and L-shaped ones, which is not conducive to packaging, storage, transportation, and handling;

[0004] Secondly, when the anchor bolts are assembled with the steel plate, the direction of the bent part at the bottom of the bolts will be adjusted according to the center of gravity of the equipment to be installed, so that the embedded parts can provide better support. However, the traditional anchor bolts are cylindrical and can rotate after being connected with the steel plate. At this time, during the tightening process of the nut, since the bolts, steel plate connection holes and nuts are in a coaxial state, the anchor bolts will rotate with them, and the direction of the bent part at the bottom of the bolts will change accordingly, so the reliability preset before the embedded parts are not achieved;

[0005] In order to solve the above problems, a reinforced anchor bolt is proposed in the present application. Utility Model Content

[0006] The purpose of the utility model is to provide a reinforced anchor bolt to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] The utility model is a reinforced anchor bolt, comprising a vertical pole and a first bent rod formed on one side of the bottom of the vertical pole, a polygonal rod is welded on the upper end of the vertical pole, a polygonal sleeve with a fixed distance adjustable orientation is sleeved on the outside of the polygonal rod, a second bent rod is welded on the side of the polygonal sleeve, the polygonal rod is longer than the polygonal sleeve, a stud is welded on the upper end of the polygonal rod, a nut is arranged on the outside of the stud, the anchor bolt is assembled with a steel plate, and a polygonal hole is opened on the steel plate for plugging into the part of the polygonal rod that is longer than the polygonal sleeve.

[0009] Furthermore, the diameter of the polygonal rod is smaller than that of the vertical rod, and a step is formed therebetween to limit the bottom of the polygonal sleeve.

[0010] Further, the diameter of the stud is smaller than that of the polygonal rod. The stud penetrates through the polygonal hole and is locked to the steel plate by a nut.

[0011] Further, the diameter of the stud is smaller than that of the polygonal rod. The stud penetrates through the polygonal hole and is locked to the steel plate by a nut.

[0012] Further, the polygonal sleeve axially fits with the polygonal rod from the side where the stud is provided.

[0013] Further, the bottoms of the polygonal rod and the polygonal sleeve are flush, and the part of the top of the polygonal rod protruding from the polygonal sleeve is inserted into the polygonal hole.

[0014] Further, the orientation of the vertical rod and the second bent rod is limited by the fitting of the polygonal rod and the polygonal sleeve, and the orientation between the vertical rod and the second bent rod and the steel plate is limited by the insertion of the polygonal rod into the polygonal hole.

[0015] The utility model has the following beneficial effects:

[0016] By providing a second bent rod that is separate from the first bent rod and whose orientation is adjustable in the utility model, the position can be adjusted according to the actual installation requirements and the center of gravity of the equipment, so as to achieve a better supporting effect. Moreover, when packing, the first bent rod and the second bent rod can be placed on the same side, effectively controlling the occupied space in the packing state, and thus facilitating handling, transportation, and storage.

[0017] In the utility model, by inserting the top of the polygonal rod into the polygonal hole, the orientation of the first bent rod and the second bent rod is directly limited after the two are docked. At this time, the polygonal sleeve abuts against the bottom of the steel plate, and the nut will not change the positions among the vertical rod, the first bent rod, and the second bent rod during the tightening process, which not only facilitates the assembly work but also ensures the stability of the embedded part is consistent with the preset effect.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] Please refer to Figures 1-4 As shown, the present utility model is a reinforced anchor bolt, including a vertical rod 1 and a first bent rod 2 formed on one side of the bottom of the vertical rod 1. A polygonal rod 3 is welded to the upper end of the vertical rod 1. A polygonal sleeve 4 that can be adjusted in distance and orientation is sleeved outside the polygonal rod 3. A second bent rod 5 is welded to the side of the polygonal sleeve 4. The length of the polygonal rod 3 is greater than that of the polygonal sleeve 4. A stud 6 is welded to the upper end of the polygonal rod 3. A nut 7 is provided outside the stud 6. The anchor bolt is assembled in cooperation with a steel plate 8. A polygonal hole 9 into which the part of the polygonal rod 3 longer than the polygonal sleeve 4 is inserted is opened on the steel plate 8.

[0029] Among them, the diameter of the polygonal rod 3 is smaller than that of the vertical rod 1, and a step for limiting the bottom of the polygonal sleeve 4 is formed therebetween. In this embodiment, the bottom of the polygonal sleeve 4 is limited by the step formed by the diameter difference between the vertical rod 1 and the polygonal rod 3. The top of the polygonal sleeve 4 abuts against the steel plate 8, so as to form mutual support and positioning, and the degree of fit is high.

[0030] Among them, the top of the polygonal rod 3 is flush with the top of the steel plate 8, and the top of the polygonal sleeve 4 contacts the bottom end of the steel plate 8. In this embodiment, the vertical rod 1, the polygonal rod 3, the polygonal sleeve 4, and the steel plate 8 are locked by the stud 6 and the nut 7.

[0031] Among them, the diameter of the stud 6 is smaller than that of the polygonal rod 3. The stud 6 passes through the polygonal hole 9 and is locked on the steel plate 8 by the nut 7. In this embodiment, the diameter of the stud 6 being smaller than that of the polygonal rod 3 facilitates the fitting and adjustment of the polygonal rod 3 and the polygonal sleeve 4 without affecting the stud 6, with high flexibility.

[0032] Among them, the polygonal sleeve 4 is axially fitted with the polygonal rod 3 from the side where the stud 6 is provided. The bottoms of the polygonal rod 3 and the polygonal sleeve 4 are flush, and the part of the top of the polygonal rod 3 protruding from the polygonal sleeve 4 is inserted into the polygonal hole 9. In this embodiment, the structures of the polygonal rod 3, the polygonal sleeve 4, and the polygonal hole 9 are simple and easy to assemble. At the same time, they support each other after assembly and can be locked with the steel plate 8 through the stud 6 and the nut 7, which is convenient to use.

[0033] Among them, the orientation of the vertical rod 1 and the second bent rod 5 is limited by the fitting of the polygonal rod 3 and the polygonal sleeve 4, and the orientation between the vertical rod 1 and the second bent rod 5 and the steel plate 8 is limited by the insertion of the polygonal rod 3 into the polygonal hole 9. In this embodiment, through the cooperation between the polygonal rod 3, the polygonal sleeve 4, and the polygonal hole 9, the positions of the first bent rod 2, the second bent rod 5, and the vertical rod 1 can be limited while being adjustable, facilitating flexible adjustment according to the actual installation equipment requirements.

[0034] It can be understood that, first, setting the split first bent rod and second bent rod can adjust the direction according to the actual embedding requirements. At the same time, the two can be folded in one plane, improving flexibility and reliability while facilitating work such as packing and transportation. Second, setting the insertion of the polygonal sleeve and the polygonal hole can play a positioning role for the vertical rod, the first bent rod, and the second bent rod when the nut is locked, ensuring that the assembled embedded part can reach the preset supporting force.

[0035] A specific application of this embodiment is as follows: The vertical rod 1 and the first bent rod 2 are bent and formed. The polygonal rod 3 and the stud 6 are welded to the vertical rod 1 in sequence, and the second bent rod 5 is welded to the polygonal sleeve 4. After production, it is assembled and packed in the state as Figure 4 shown;

[0036] During use: By varying the mating surfaces of the polygonal rod 3 and the polygonal sleeve 4, the orientations of the first bent rod 2 and the second bent rod 5 can be adjusted. At the same time, by varying the mating surfaces of the top of the polygonal sleeve 4 and the polygonal hole 9, the orientations of the first bent rod 2 and the second bent rod 5 on the vertical rod 1 can be adjusted. Then, insert the stud 6 through the polygonal hole 9. At this time, the top of the polygonal rod 3 is inserted into the polygonal hole 9, and the top of the polygonal sleeve 4 is in contact with the bottom of the steel plate 8. Screw the nut 7 onto the stud 6 from above the steel plate 8 to lock them tightly;

[0037] In the figure, only a part of the steel plate 8 is shown.
