Technical Field

[0001] The utility model belongs to the technical field of anchor bolts, and particularly relates to an extended internal and external thread anchor bolt with a reinforcement structure. Background Technique

[0002] When a mechanical component is installed on a concrete foundation, one end of this bolt in the shape of J or L is buried in the concrete. The tensile capacity of the anchor bolt is the tensile capacity of the round steel itself, and its magnitude is equal to the cross-sectional area multiplied by the allowable stress value, which is the allowable tensile bearing capacity during design. Anchor bolts are generally made of Q235 steel, which is smooth round. The burial depth and the hook are both to ensure the friction between the bolt and the foundation, so as not to cause the bolt to be pulled out and damaged.

[0003] The existing anchor bolts are of an integral forming structure. In order to have a high-strength supporting capacity, the common method is to achieve it by changing its own material. However, this method has a large upfront investment cost and a long R & D cycle, and its promotion in actual use is relatively poor. At the same time, the existing anchor bolts have a single form and cannot adapt to special processing requirements, so there is room for improvement. Content of the Utility Model

[0004] The purpose of the utility model is to provide an extended internal and external thread anchor bolt with a reinforcement structure, so as to solve the problems of long cycle and large investment cost in the existing method of improving the strength of anchor bolts by changing materials as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An extended internal and external thread anchor bolt with a reinforcement structure, including a main body.

A reinforcement component is arranged at the vertical part of the main body to improve the anti-deformation ability of the anchor bolt. The reinforcement component includes a plurality of support rods, and sleeves are welded at both ends of the support rods. Welding holes are opened on the surface of the sleeves for quickly installing the sleeves. Both the sleeves and the support rods are sleeved outside the main body.

[0006] Preferably, the reinforcement component further includes connecting threads opened on the surface of the horizontal part and the bottom surface of the vertical part. A reinforcement block is threadedly sleeved in the area of the connecting threads. This reinforcement block can increase the contact area with the concrete and improve the installation stability. The reinforcement block is a hollow frustum structure.

[0007] Preferably, a steel bar hoop is further arranged outside the vertical part of the main body. The diameter of the steel bar hoop is smaller than the diameter of the main body, which can conveniently tighten the main body during installation. The steel bar hoop and the vertical part of the main body are distributed perpendicular to each other.

[0008] Preferably, a side groove is formed on the side of the vertical part of the main body, an arc plate is placed inside the side groove, a guiding groove is formed on the inner wall of the opening of the side groove to facilitate the cutting by a cutting device, a gap exists between the arc plate and the side groove, and a reinforcing protrusion is fixed on the other side of the vertical part of the main body.

[0009] Preferably, a welding point exists between the arc plate and the side groove to ensure the stable installation of the two, and the welding point is located between the bottom end of the guiding groove and the arc plate.

[0010] Preferably, the reinforcing protrusion has the same length as the side groove and they are on the same plane to ensure the stability of the main body is not affected. The thickness of the reinforcing protrusion is equal to the inner depth of the side groove, and threads for connection are provided on both the inner and outer walls of the vertical part of the main body.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3 Figures 1 to 3 , the present utility model provides a technical solution: an extended internal and external thread anchor bolt with a reinforcement structure, including a main body 1. The bottom of the main body 1 is bent and forms a horizontal part and a vertical part. A reinforcement component is provided at the vertical part of the main body 1. Through the designed reinforcement component, the anti-deformation ability and installation stability of the anchor bolt can be greatly improved. Compared with the method of improving by changing materials, it is simpler and easier to process, has strong promotion performance, and does not affect normal use, improving the deficiencies in the existing structure. The reinforcement component includes a plurality of support rods 5. Sleeve rings 2 are welded at both ends of the support rods 5. Welding holes 7 are formed on the surface of the sleeve rings 2. Both the sleeve rings 2 and the support rods 5 are sleeved outside the main body 1. The reinforcement component further includes connecting threads 4 opened on the surface of the horizontal part and the bottom surface of the vertical part. Reinforcement blocks 3 are threadedly sleeved in the area of the connecting threads 4, which can increase the contact area during concrete pouring. The reinforcement blocks 3 are hollow frustum structures.

[0020] In this embodiment, preferably, a steel bar hoop 6 is further provided outside the vertical part of the main body 1. The diameter of the steel bar hoop 6 is smaller than the diameter of the main body 1. The steel bar hoop 6 and the vertical part of the main body 1 are distributed perpendicular to each other. A side groove 10 is opened on the side of the vertical part of the main body 1. Through the provided hidden side groove 10, the method of tying with steel wire ropes can be omitted to achieve connection during the connection with the steel bar hoop 6, and at the same time, the installation stability is improved. And during non-use, it will not affect the strength of the anchor bolt. This kind of structure can be applied to areas with high installation stability. An arc plate 9 is placed inside the side groove 10. A guiding groove 8 is formed on the inner wall of the opening of the side groove 10. There is a gap between the arc plate 9 and the side groove 10, which is convenient for later cutting and separation. A reinforcing protrusion 11 is fixed on the other side of the vertical part of the main body 1. There is a welding point between the arc plate 9 and the side groove 10, and this welding point is between the bottom end of the guiding groove 8 and the arc plate 9. The length of the reinforcing protrusion 11 is equal to that of the side groove 10, and the two are on the same plane, which can ensure the support stability. The thickness of the reinforcing protrusion 11 is equal to the inner depth of the side groove 10. Threads for connection are opened on both the inner and outer walls of the vertical part of the main body 1 to form internal and external threads for installation.

[0021] Working principle and usage process of the present utility model: When the present utility model is in use, the reinforcement block 3 is screwed onto the connecting thread 4 at the bottom of the main body 1. After the installation is completed, the bottom of the main body 1 is placed into the concrete. The installation stability is improved by the bending of the main body 1 itself and by increasing the contact area with the concrete through the reinforcement block 3. During use, the main body 1 in the area outside the concrete is supported and reinforced by the support rod 5. When installing the support rod 5, the collar 2 is first welded to both ends of the support rod 5, and then the collar 2 is welded to the main body 1 through the welding hole 7. When multiple main bodies 1 need to be formed into an installation base through the steel hoop 6, the external cutting device can be inserted into the gap between the arc plate 9 and the side groove 10 from the guide groove 8 to separate the arc plate 9 from the side groove 10. Finally, the steel hoop 6 is snapped into the inside of the side groove 10. At this time, the steel hoop 6 is engaged and limited with the main body 1. After the steel hoop 6 is tightened later, the limiting installation between the steel hoop 6 and the main body 1 can be completed. The overall length of the main body 1 is relatively long and can be applied to the installation of larger buildings.
