Description

TECHNICAL FIELD

[0001] The utility model relates to building construction auxiliary device technical field, concretely is a building component ground anchor reinforcing device. BACKGROUND

[0002] In the field of building engineering, the stable anchoring of building components plays a crucial role in the safety and stability of the entire building structure. As a common anchoring means, the ground anchor reinforcing device is widely used in various building foundations, tower crane foundations, slope protection and other engineering scenes.

[0003] For example, the existing patent (publication number: CN212129132U) discloses a building component ground anchor reinforcing device, which is provided with barbs one and two on both sides of the ground anchor body, which are both conical structures, with the conical barbs two and one being inclined outward, and the end face of the conical end is provided with a pit. During the installation of the ground anchor, the pit can play the role of tamping the soil around the ground anchor, making the anchoring of the ground anchor more secure.

[0004] However, the above-mentioned device has some shortcomings in actual use: although the barbs on both sides of the ground anchor can tamp the soil around the ground anchor, the barbs on both sides are fixedly arranged, which makes it inconvenient to operate when the ground anchor is inserted into the soil. During the insertion process, the fixed barbs will encounter a large soil resistance, which not only increases the difficulty of insertion and the required driving force, but also easily causes excessive disturbance to the soil structure, destroys the original stability of the soil body, and further affects the final anchoring effect of the ground anchor. At the same time, the design of the fixed barbs lacks flexibility and cannot be self-adapted according to different soil conditions. In the face of complex geological environment, it is difficult to ensure consistent and efficient anchoring performance. Once the barb is damaged or deformed due to encountering hard obstacles during insertion, due to its fixed and non-adjustable characteristics, it cannot be repaired or re-adjusted, and only the entire ground anchor device can be replaced, which increases the engineering cost and construction time.

[0005] Therefore, we designed a building component ground anchor reinforcing device to solve the above problems. UTILITY MODEL CONTENTS

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] Please refer to Figure 2 And Figure 3 The utility model provides a kind of technical scheme: a building component ground anchor reinforcing device, including ground anchor body 1, reinforcing assembly is arranged in the side wall of ground anchor body 1, reinforcing assembly includes cylindrical cavity 2, cylindrical cavity 2 is set in the side wall of ground anchor body 1, the bottom wall of cylindrical cavity 2 is installed with multiple groups of locating block 3, locating block 3 is provided with support plate 4, two locating blocks 3 between adjacent fixedly connected with rotating shaft 6, the bottom end of support plate 4 is provided with groove 5, the both sides inner wall of groove 5 is provided with insertion hole 7, support plate 4 is rotatably connected on rotating shaft 6 by insertion hole 7, the inner wall of support plate 4 is fixedly connected with tension spring 8, the other end of tension spring 8 is fixedly connected on the side wall of cylindrical cavity 2.

[0024] In the implementation, during the insertion of the ground anchor body 1, the support plate 4 in the reinforcing assembly is subjected to the resistance of the soil around the cylindrical cavity 2 as the ground anchor body 1 gradually descends in the hole. Since the support plate 4 is rotationally connected to the positioning block 3 through the rotation shaft 6 and the inner wall of the support plate 4 is connected to the tension spring 8, the support plate 4 rotates around the rotation shaft 6 and moves towards the cylindrical cavity 2 under the action of the resistance of the soil, overcoming the tension of the tension spring 8, and the tension spring 8 is compressed accordingly.

[0025] Referring to Figure 2 The reinforcing assembly is multiple, and the multiple reinforcing assemblies are uniformly distributed on the side wall of the ground anchor body 1.

[0026] In the implementation, the multiple reinforcing assemblies are uniformly distributed on the side wall of the ground anchor body 1, so that the ground anchor can obtain uniform lateral anchoring force enhancement in all directions after being inserted into the soil.

[0027] Referring to Figure 3 The number of the positioning block 3 and the support plate 4 is four, and the four positioning blocks 3 and the support plate 4 are arranged around the cylindrical cavity 2.

[0028] In the implementation, the four positioning blocks 3 and the support plate 4 are arranged around the cylindrical cavity 2, which optimizes the support and stress distribution of the support plate 4 from the perspective of structural mechanics.

[0029] Referring to Figure 1 and Figure 4 The bottom end of the ground anchor body 1 is fixedly connected with a ground spike 9, the outer wall of the ground spike 9 is slidingly sleeved with a sleeve 10, the side of the sleeve 10 away from the ground spike 9 is hingedly connected with an anchor claw 11 through a hinge base, the top end outer wall of the anchor claw 11 is hingedly connected with a connecting rod 12, and the other end of the connecting rod 12 is hingedly connected to the bottom end of the ground anchor body 1.

[0030] In the implementation, during the insertion of the ground spike 9 at the bottom end of the ground anchor body 1 into the soil at the bottom end of the hole, the sleeve 10 moves upward due to the extrusion of the soil at the bottom end. Since the anchor claw 11 is hingedly connected to the bottom end of the ground anchor body 1 through the connecting rod 12 and the sleeve 10 is connected to the anchor claw 11 through the hinge base, as the sleeve 10 moves upward, the anchor claw 11 and the connecting rod 12 rotate, and the anchor claw 11 gradually changes from the original state of the top end facing upward to the direction of the soil at both ends of the hole and is inserted into the soil at both ends.

[0031] Referring to Figure 4 The number of the anchor claw 11 and the connecting rod 12 is two, and the two anchor claws 11 and the connecting rod 12 are symmetrically arranged on both sides of the ground spike 9.

[0032] In the implementation, the two anchor claws 11 and the connecting rod 12 symmetrically arranged on both sides of the ground spike 9 achieve balanced and symmetrical force transmission and anchoring enhancement in structure.

[0033] Referring to Figure 1The top plates 13 on both sides of the top end of the ground anchor body 1 are provided with bolts 14 which are screwed on the top plates 13, and the bottom end of the bolt 14 is provided with an insertion block 15 which is in the shape of a cone.

[0034] In the embodiment, the top plates 13 on both sides of the top end of the ground anchor body 1 provide a stable connection basis for the connection with the building component, the bolt 14 screwed on the top plate 13 can be adjusted in the up-down position by rotating the bolt 14, and when connecting the building component, the bolt 14 is passed through the corresponding mounting hole on the building component, and then the bolt 14 is tightened, so that the cone-shaped insertion block 15 at the bottom end of the bolt 14 is inserted into the connection part of the building component.

[0035] Working principle: when installing the ground anchor reinforcing device for the building component, first, the position and insertion depth of the ground anchor body 1 are determined according to the design requirements, a hole with a corresponding depth is drilled on the ground or foundation by using a drilling device, then the bottom end of the ground anchor body 1 is aligned with the hole, and the ground anchor body 1 is inserted into the hole by hammering or static pressure, until the design depth is reached. During the insertion process, as the ground anchor body 1 gradually descends in the hole, the support plate 4 in the reinforcing assembly is subjected to the resistance of the soil around the cylindrical cavity 2. Since the support plate 4 is rotationally connected with the positioning block 3 through the rotating shaft 6 and the inner wall of the support plate 4 is connected with the tension spring 8, the support plate 4 rotates around the rotating shaft 6 and moves towards the cylindrical cavity 2 under the action of the soil resistance, and the tension spring 8 is compressed accordingly.

[0036] When the ground anchor body 1 stops moving and reaches the design depth, the tension spring 8 is in a compressed state due to the previous compression, and at this time, the elastic force generated by the tension spring 8 acts on the support plate 4, so that the support plate 4 exerts a pressing force on the surrounding soil, thereby enhancing the friction and anchoring force between the side wall of the ground anchor body 1 and the soil.

[0037] At the same time, when the ground anchor body 1 moves to the bottom end of the hole, the ground nail 9 at the bottom end of the ground anchor body 1 starts to be inserted into the soil at the bottom end of the hole. During the insertion process, the sleeve 10 moves upward due to the extrusion of the soil at the bottom end. Since the anchor claw 11 is hinged to the bottom end of the ground anchor body 1 through the connecting rod 12, and the sleeve 10 is connected with the anchor claw 11 through the hinge seat, as the sleeve 10 moves upward, the anchor claw 11 and the connecting rod 12 rotate, and the anchor claw 11 gradually changes from the original state of the top end facing upward to the direction facing the soil on both sides of the hole and is inserted into the soil at both ends, which further increases the anchoring force at the bottom end of the ground anchor body 1.
