Description

Technical Field

[0001] This utility model relates to the field of anchor bolt reaction frames, specifically a high-stability anchor bolt reaction frame. Background Technology

[0002] Anchor bolts are structural components widely used in geotechnical engineering. Their main functions include support, reinforcement, and stabilization. When the anchor bolt's body material is steel strand or high-strength steel wire bundle, it can also be called an anchor cable. The specific installation method involves drilling a hole in the natural strata until reaching a stable stratum. An anchor body is inserted into the stable stratum through the hole, then a reinforcing bar or steel strand is inserted to connect the anchor body. Finally, cement mortar is poured into the hole to form a fixed anchor bolt.

[0003] Existing anchor bodies are generally cylindrical or frame-shaped reaction frames, which makes it difficult to effectively disperse the force acting on the anchor body when the anchor rod is under stress, resulting in local stress concentration and affecting the stability of the overall structure. For reaction frame type anchor bodies, the connection points between the frames are very likely to become stress concentration points. Once broken, the reaction frame will lose its function and the tensile strength of the anchor rod will drop significantly.

[0004] The research objective of this utility model is to design a highly stable anchor reaction frame to address the problems existing in the above-mentioned prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a highly stable anchor reaction frame, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A high-stability anchor reaction frame, comprising:

[0008] The base has a through hole.

[0009] The top seat is arranged parallel to and spaced apart from the base, and has a second through hole extending through it;

[0010] A plurality of connectors are vertically connected between the base and the top seat, and the two ends of the plurality of connectors are respectively provided with a first reinforcing structure and a second reinforcing structure at the connection points with the base and the top seat. The plurality of connectors enclose to form a through channel connecting the first through hole and the second through hole. The first through hole, the through channel, and the second through hole are used to install corresponding anchors through the through hole.

[0011] Several reinforcing members are provided, and the reinforcing members are vertically connected to each other between adjacent connecting members.

[0012] Furthermore, a plurality of the connectors are arranged in a ring at intervals, and a plurality of the reinforcing members are arranged in a ring at intervals and respectively fixedly and vertically connected to the middle of adjacent connectors, and the outer diameter of the top seat is smaller than the outer diameter of the base.

[0013] Furthermore, the base and the top seat have a first boss and a second boss protruding from their opposite sides, and the two ends of the connector are respectively provided with a first reinforcing part and a second reinforcing part that are vertically fixed to the first boss and the second boss. The first reinforcing structure includes the first boss and the first reinforcing part, and the second reinforcing structure includes the second boss and the second reinforcing part. The thickness of the first reinforcing part and the second reinforcing part is greater than the thickness of the connector.

[0014] Furthermore, the outer ends of several first reinforcing portions extend outward along the outer periphery of the first boss to form first reinforcing feet that vertically and fixedly connect the first boss and the base, and the outer ends of several second reinforcing portions extend outward along the outer periphery of the second boss to form second reinforcing feet that vertically and fixedly connect the second boss and the top seat.

[0015] Furthermore, the outer periphery of the first boss is inclined and its outer diameter gradually decreases in the direction away from the base, the outer periphery of the second boss is inclined and its outer diameter gradually decreases in the direction away from the top seat, the first reinforcing foot is inclined and adapted to the outer periphery of the first boss, and the second reinforcing foot is inclined and adapted to the outer periphery of the second boss.

[0016] Furthermore, both the top seat and the base are annular, the number of connectors is four and their widths extend radially along the top seat and the base, and adjacent connectors are arranged vertically. The number of reinforcing members is four and their widths extend laterally, and adjacent reinforcing members are arranged vertically. The four reinforcing members are offset outward and their two ends are folded inward to form a reinforcing part that vertically and fixedly connects the middle of the adjacent connectors.

[0017] Furthermore, the anchor includes an anchor and an anchor rod that passes through and connects to the anchor, and the top seat has a protruding retaining ring on the side away from the base for inserting the anchor.

[0018] Furthermore, the top seat, base, connector, and reinforcing member are integrally formed.

[0019] Therefore, the beneficial effects of this utility model are:

[0020] 1. By setting several intersecting vertical connectors and reinforcing members between the parallel-spaced top seat and base, the overall force balance and uniformity of the reaction frame are improved. The connections between the top seat and base and the connectors, as well as between the connectors and reinforcing members, are all set to be vertical connections, thus forming several right-angle structures on the reaction frame. These right-angle structures allow the force on the reaction frame to be evenly distributed to several perpendicular components, reducing the possibility of local stress concentration and improving the overall stability of the reaction frame. This can greatly improve the overall bending and shear resistance of the reaction frame. At the same time, a first reinforcing structure and a second reinforcing structure are set at the connection points of the connectors with the base and top seat to improve the structural strength of the connection points that are prone to stress concentration, further improving the overall structural strength of the reaction frame.

[0021] 2. By forming a reaction frame structure with a smaller top and a larger bottom through the top seat and base, the overall center of gravity of the reaction frame is lowered, the overturning resistance is improved, and the effect of dispersing the force downward and transmitting it to the stabilizing layer is improved, reducing local stress concentration.

[0022] 3. By vertically fixing the thickened first and second reinforcing parts to the thickened first and second protrusions, the structural stability of the connection points between the two ends of the connector and the base and top seat is improved, thereby enhancing the overall structural strength and stability of the reaction frame. Furthermore, under the structural reinforcement effect of the first and second reinforcing parts and the reinforcing members, the thickness of the connector itself can be appropriately reduced. This reduces the overall weight of the reaction frame while ensuring the above-mentioned effects and the overall bending and shear resistance of the reaction frame, thereby reducing material usage, significantly reducing manufacturing costs, and improving the economy of the reaction frame.

[0023] 4. By adding the first and second reinforcing feet, the connection area between the first and second reinforcing parts and the base and top seat is increased, thereby improving the connection strength. Furthermore, this creates several support points from the inside out and from high to low between the first and second reinforcing parts and the first reinforcing feet, and similarly, several support points from the inside out and from high to low between the second and second reinforcing parts. The support points corresponding to the first and second reinforcing feet are located on the outside of several connecting parts. Thus, when the reaction frame is subjected to lateral force, the first reinforcing foot abuts against the outside of the first reinforcing part and the base, and the second reinforcing foot abuts against the outside of the second reinforcing part and the base. This not only allows the ends of several connecting parts to be supported by multiple points from the inside out and from high to low, but also provides structural support for the first and second reinforcing parts through the first and second reinforcing feet. This reduces the possibility of the connecting parts, the first reinforcing part, and the second reinforcing part bending outwards and breaking under stress, further improving the structural strength of the connection points between the ends of the connecting parts and the base and top seat. This makes the reaction frame more stable under lateral force, preventing tilting or twisting.

[0024] 5. By tilting the outer periphery of the first and second bosses and setting the first and second reinforcing feet to be tilted accordingly, the connection area between the first and second reinforcing parts and the base and top seat is increased, and the uniformity of the distribution of the support points of the corresponding first and second reinforcing feet from the inside to the outside and from high to low is improved. This increases the support strength of the first and second reinforcing feet on the outer side of the first and second reinforcing parts, thereby improving the shear resistance of the first and second reinforcing parts and the connecting parts against lateral forces.

[0035] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0036] refer to Figure 1-4 A high-stability anchor bolt reaction frame, which can be used not only for tensioning anti-buoyancy anchor bolts, but also for providing stable reaction force during the tensioning and retrieval of pressure-type anchor cables, the reaction frame comprising:

[0037] The base 1 has a through hole 11.

[0038] Top seat 2 is arranged parallel to and spaced apart from the base 1 and has a second through hole 21 extending through it;

[0039] A plurality of connectors 3 are vertically connected between the base 1 and the top seat 2, and the two ends of the plurality of connectors 3 are respectively provided with a first reinforcing structure and a second reinforcing structure at the connection between the base 1 and the top seat 2. The plurality of connectors 3 form a through channel 31 that connects the first through hole 11 and the second through hole 21. The first through hole 11, the through channel 31, and the second through hole 21 are used to install the corresponding anchors 5 through the through.

[0040] Several reinforcing members 4 are provided, and the reinforcing members 4 are vertically connected between adjacent connecting members 3.

[0041] The above-described structure improves the overall balance and uniformity of the force distribution on the reaction frame by setting several intersecting vertical connectors 3 and reinforcing members 4 between the parallel-spaced top seat 2 and base 1. The connections between the top seat 2 and base 1 and the connectors 3, as well as between the connectors 3 and reinforcing members 4, are all vertically connected, forming several right-angle structures on the reaction frame. These right-angle structures allow the force on the reaction frame to be evenly distributed to several perpendicular components, reducing the possibility of local stress concentration and improving the overall stability of the reaction frame. This significantly enhances the overall bending and shear resistance of the reaction frame. Simultaneously, a first reinforcing structure and a second reinforcing structure are provided at the connection points between the connectors 3 and the base 1 and top seat 2 to improve the structural strength of these connection points, which are prone to stress concentration, further enhancing the overall structural strength of the reaction frame.

[0042] Specifically, several connecting members 3 are arranged in a ring at intervals, and several reinforcing members 4 are arranged in a ring at intervals and are respectively fixed vertically connected to the middle of adjacent connecting members 3. The outer diameter of the top seat 2 is smaller than the outer diameter of the base 1. Thus, the top seat 2 and the base 1 form a reaction frame structure that is smaller at the top and larger at the bottom, which lowers the overall center of gravity of the reaction frame, improves the anti-overturning ability, and enhances the effect of dispersing the force downward and transmitting it to the stabilizing layer, thereby reducing local stress concentration.

[0043] To improve the structural strength of the connection between the two ends of the connector 3 and the base 1 and the top seat 2, the base 1 and the top seat 2 are respectively provided with a first boss 12 and a second boss 22 on their opposing sides. The two ends of the connector 3 are respectively provided with a first reinforcing part 32 and a second reinforcing part 33 that are vertically fixed to the first boss 12 and the second boss 22. The first reinforcing structure includes the first boss 12 and the first reinforcing part 32, and the second reinforcing structure includes the second boss 22 and the second reinforcing part 33. The thickness of the first reinforcing part 32 and the second reinforcing part 33 is greater than the thickness of the connector 3. By vertically fixing the thickened first reinforcing part 32 and the second reinforcing part 33 to the thickened first boss 12 and the second boss 22, the structural stability of the connection between the two ends of the connector 3 and the base 1 and the top seat 2 is improved, thereby enhancing the overall structural strength and stability of the reaction frame. On this basis, under the structural reinforcement of the first reinforcing part 32, the second reinforcing part 33, and the reinforcing part 4, the thickness of the connector 3 itself can be appropriately reduced. Thus, while ensuring the above effects and the overall bending and shear resistance of the reaction frame, the overall weight of the reaction frame is reduced, thereby reducing material usage, significantly reducing manufacturing costs, and improving the economy of the reaction frame.

[0044] To further enhance the effectiveness of the first reinforcing part 32 and the second reinforcing part 33, the outer ends of several of the first reinforcing parts 32 extend outward along the outer periphery of the first boss 12 to form first reinforcing feet 34 that vertically and fixedly connect the first boss 12 and the base 1. Similarly, the outer ends of several of the second reinforcing parts 33 extend outward along the outer periphery of the second boss 22 to form second reinforcing feet 35 that vertically and fixedly connect the second boss 22 and the top seat 2. This structure, through the addition of the first reinforcing feet 34 and the second reinforcing feet 35, increases the connection area between the first reinforcing parts 32 and 33 and the base 1 and the top seat 2, thereby improving the connection strength. Furthermore, it creates several support points between the first reinforcing parts 32 and the first reinforcing feet 34, and between the second reinforcing parts 33 and the second reinforcing feet 35, also creating several support points between the second reinforcing parts 33 and the second reinforcing feet 35, with the support points corresponding to the first reinforcing feet 34 and 35 located outside several connecting members 3. Therefore, when the reaction frame is subjected to a lateral force, the first reinforcing feet 34 abut against the first reinforcing parts 32 and 33. Between the outer side of the second reinforcing part 33 and the base 1, the second reinforcing foot 35 is abutted between the outer side of the second reinforcing part 33 and the base 1. This not only allows the two ends of several connecting parts 3 to be supported by several support points from the inside out and from high to low, but also provides structural support for the first reinforcing part 32 and the second reinforcing part 33 through the first reinforcing foot 34 and the second reinforcing foot 35. This reduces the possibility of the connecting parts 3, the first reinforcing part 32, and the second reinforcing part 33 bending outward and breaking after being subjected to force. It further improves the structural strength of the connection between the two ends of the connecting parts 3 and the base 1 and the top seat 2, making the reaction frame more stable under the action of lateral force and preventing tilting or twisting.

[0045] To further increase the connection area between the first reinforcing part 32 and the second reinforcing part 33 and the base 1 and the top seat 2, the outer periphery of the first boss 12 is inclined and the outer diameter gradually decreases in the direction away from the base 1. The outer periphery of the second boss 22 is also inclined and the outer diameter gradually decreases in the direction away from the top seat 2. The first reinforcing foot 34 is inclined to match the outer periphery of the first boss 12, and the second reinforcing foot 35 is inclined to match the outer periphery of the second boss 22. Specifically, the inclination angle of the first reinforcing foot 34 and the second reinforcing foot 35 is set to 45°. The above structure increases the connection area between the first reinforcing part 32 and the second reinforcing part 33 and the base 1 and the top seat 2 by tilting the outer periphery of the first protrusion 12 and the second protrusion 22 and setting the first reinforcing foot 34 and the second reinforcing foot 35 to be adapted to tilt, thereby increasing the uniformity of the distribution of the support points of the corresponding first reinforcing foot 34 and the second reinforcing foot 35 from the inside to the outside and from high to low, and increasing the support strength of the first reinforcing foot 34 and the second reinforcing foot 35 on the outside of the first reinforcing part 32 and the outside of the second reinforcing part 33, thereby improving the shear resistance of the first reinforcing part 32, the second reinforcing part 33 and the connecting member 3 against lateral forces.

[0046] To improve the three-dimensional structural stability and load-bearing capacity of the reaction frame, both the top seat 2 and the base 1 are annular. Four connectors 3 are provided, each extending radially along the top seat 2 and base 1. Adjacent connectors 3 are perpendicularly positioned. Four reinforcing members 4 are provided, extending laterally. Adjacent reinforcing members 4 are perpendicularly positioned. The four reinforcing members 4 are offset outwards, with their ends folded inwards to form a reinforcing section 41 that vertically and securely connects the middle of adjacent connectors 3. This structure ensures that the components of the reaction frame are vertically connected both vertically and laterally, forming a stable three-dimensional structure. Furthermore, the addition of the reinforcing section 41 ensures that the ends of the reinforcing members 4 are perpendicular to the middle of the connectors 3, enhancing the structural stability of the vertical connection and improving the uniformity of force distribution. It also allows the reinforcing members 4 to be offset outwards, preventing excessive concentration of the reaction frame's center of gravity and improving the overall force balance of the reaction frame.

[0047] Specifically, the anchor 5 includes an anchor 51 and an anchor rod 52 that passes through and connects to the anchor 51. The top seat 2 has a protruding retaining ring 23 on the side away from the base 1 for inserting the anchor 51. The specific installation method is as follows: after the reaction frame is placed in the stabilizing layer, the anchor 51 with the anchor rod 52 is inserted into the retaining ring 23, and the anchor rod 52 is fixed by passing through the first through hole 11, the through channel 31, and the second through hole 21 and then filled with concrete or grout. Finally, concrete or grout is filled to fix the reaction frame to the stabilizing layer, thus completing the installation of the anchor rod 52 and the reaction frame.

[0048] To improve the overall structural strength of the reaction frame, the top seat 2, base 1, connector 3, and reinforcing member 4 are integrally formed. Specifically, the reaction frame as a whole can be formed by casting molten iron.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
