Description

Technical Field

[0001] This utility model relates to the field of load-bearing foundation reinforcement technology, and in particular to a load-bearing foundation reinforcement device. Background Technology

[0002] Building load-bearing foundations refer to the load-bearing structures below ground level of a building. In this structural system, the foundation pit is a crucial early-stage construction element. It refers to the space excavated below ground level for the construction of the building's foundation and basement. Subsequent foundation component construction must be completed within the foundation pit. Building load-bearing foundations include foundation caps, frame columns, ground beams, and other foundation components. These components are located at the very bottom of the building, in direct contact with the ground. Their core function is to smoothly transfer various loads borne by the superstructure to the ground, ensuring the overall stability and safety of the building. Strengthening building load-bearing foundations is a key technology for comprehensively improving building performance. It can significantly enhance the building's disaster resistance, withstand the impact of earthquakes, typhoons, and other disasters to reduce the risk of collapse, while simultaneously increasing the foundation's bearing capacity, preventing cracking and deformation caused by overloading, and protecting the lives and property of residents. Chinese Patent Announcement No. CN215759235U provides a building foundation strengthening structure. Its core technology involves using hydraulic jacks to press a new reinforced foundation cap into the building foundation cap to enhance the foundation's bearing capacity. However, the patented solution still has obvious defects in its implementation. Its installation process involves multiple complex procedures such as hydraulic jack pile driving, anchor bolt implantation, welding, and concrete pouring, which consumes a lot of time. It cannot provide timely emergency reinforcement of the foundation when there are emergency safety hazards (such as sudden settlement, rapid crack propagation, etc.), and it is difficult to meet the needs of emergency reinforcement scenarios. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a load-bearing foundation reinforcement device, which can perform emergency reinforcement of the foundation.

[0004] According to an embodiment of the present invention, a load-bearing foundation reinforcement device includes a first connecting part; a second connecting part; and a force-applying mechanism. The first connecting part and the second connecting part are connected through the force-applying mechanism, which applies a pulling force to the first connecting part and the second connecting part, causing them to approach each other. The first connecting part can be connected to the foundation pit, and the second connecting part can be connected to the foundation body, so that the second connecting part applies an upward pulling force to the foundation body and restricts the foundation body from sinking. The first connecting part and the second connecting part can be connected to both sides of the foundation body simultaneously, so that the first connecting part and the second connecting part apply a pulling force to both sides of the foundation body respectively, and cause the crack between the two sides of the foundation body to close.

[0005] It has at least the following beneficial effects: When the foundation begins to subside, the operator quickly and securely attaches the first connecting part to the pit and the second connecting part to the foundation. Since the first connecting part is connected to the pit and the second connecting part to the foundation, and the force-applying mechanism simultaneously applies a pulling force to both parts, this pulling force is converted into an upward pulling force exerted by the second connecting part on the foundation. This force effectively counteracts the subsidence trend, limiting further subsidence and preventing further deterioration. When cracks appear in the foundation, the operator quickly and securely attaches the first and second connecting parts to both sides of the foundation, with the first and second connecting parts positioned on opposite sides of the crack's direction of extension. Since the first and second connecting parts are attached to both sides of the foundation, the pulling force applied by the force-applying mechanism causes the two sides of the foundation to converge towards the center, gradually closing the cracks and reducing their width, preventing further expansion. The overall structure of this load-bearing foundation reinforcement device is simple. The implementation process only involves the installation of the first and second connecting parts and the operation of the force-applying mechanism. It does not require complicated procedures such as hydraulic jack pile driving, anchor bolt implantation, welding, and concrete pouring, which greatly shortens the implementation time. It can promptly complete emergency reinforcement work when the foundation experiences sudden settlement or rapid crack propagation, effectively meeting the needs of emergency reinforcement scenarios. At the same time, through targeted tensile force, it can respectively limit the settlement of the foundation and close the cracks, ensuring the stability and safety of the building's load-bearing foundation.

[0012] According to the load-bearing foundation reinforcement device of this utility model embodiment, the first connecting part further includes a first auxiliary plate, and the second connecting part further includes a second auxiliary plate.

The second auxiliary plate is hinged to the side of the second base plate away from the first base plate so that the angle between the second auxiliary plate and the second base plate can be adjusted.

Detailed Implementation

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figures 1 to 3 This utility model discloses a load-bearing foundation reinforcement device, including a first connecting part 100, a second connecting part 200, and a force-applying mechanism 300. The first connecting part 100 and the second connecting part 200 are connected by the force-applying mechanism 300, which applies a pulling force to the first connecting part 100 and the second connecting part 200 to bring them closer together. The first connecting part 100 can be connected to the foundation pit, and the second connecting part 200 can be connected to the foundation body 10, so that the second connecting part 200 applies an upward pulling force to the foundation body 10 and restricts the foundation body 10 from sinking. The first connecting part 100 and the second connecting part 200 can be connected to both sides of the foundation body 10 at the same time, so that the first connecting part 100 and the second connecting part 200 respectively apply a pulling force to both sides of the foundation body 10 to bring them closer together, and close the crack between the two sides of the foundation body 10.

[0021] Understandably, when the foundation 10 begins to sink, the operator quickly and securely connects the first connecting part 100 to the pit and the second connecting part 200 to the foundation 10. Since the first connecting part 100 is connected to the pit and the second connecting part 200 is connected to the foundation 10, and the force-applying mechanism 300 simultaneously applies a pulling force to the first connecting part 100 and the second connecting part 200 to bring them closer together, the pulling force applied by the force-applying mechanism 300 is converted into an upward pulling force of the second connecting part 200 on the foundation 10. This pulling force can effectively counteract the sinking trend of the foundation 10, limit the foundation 10 from sinking further, and thus prevent the sinking condition of the foundation 10 from deteriorating further. When the base 10 cracks, the operator quickly and securely connects the first connecting part 100 and the second connecting part 200 to both sides of the base 10, with the first connecting part 100 and the second connecting part 200 installed on both sides in the direction of crack extension. Since the first connecting part 100 and the second connecting part 200 are connected to both sides of the base 10, the pulling force applied by the force-applying mechanism 300 will cause the two sides of the base 10 to move closer to the middle, thereby causing the crack between the two sides of the base 10 to gradually close, reducing the crack width and preventing the crack from continuing to expand. The overall structure of this load-bearing foundation reinforcement device is simple. The implementation process only involves the installation of the first connecting part 100 and the second connecting part 200 and the operation of the force-applying mechanism 300. It does not require complicated procedures such as hydraulic jack pile driving, anchor bolt implantation, welding, and concrete pouring, which greatly shortens the implementation time. It can complete emergency reinforcement work in a timely manner when the foundation 10 experiences sudden settlement, rapid crack expansion, or other emergency safety hazards, effectively meeting the needs of emergency reinforcement scenarios. At the same time, through targeted tensile force, it can respectively limit the settlement of the foundation 10 and close the cracks, ensuring the stability and safety of the building's load-bearing foundation.

[0022] It should be explained that after the foundation reinforcement device prevents further settlement of foundation 10, the operator can first investigate the ground beneath foundation 10 to determine the cause of the settlement. If the ground is soft, high-pressure grouting can be used to inject cement grout, cement mortar, or other reinforcing grout into the ground. After the grout solidifies, it will enhance the bearing capacity of the foundation. If there are local cavities, the cavities can be filled with sand, gravel, concrete, or other filling materials until the foundation structure is stable. After the reinforcement of foundation 10 is completed, the load-bearing foundation reinforcement device can be removed for reuse. After the load-bearing foundation reinforcement device prevents the cracks on foundation 10 from continuing to expand, the operator must first clean the dust, debris, and loose concrete blocks from the surface of the cracks. Then, depending on the crack width, an appropriate repair method can be selected, such as injecting a low-viscosity repair agent like epoxy resin into the crack, or filling the crack with concrete or polymer mortar. After the crack repair is completed, the operator can remove the load-bearing foundation reinforcement device for reuse. It should be noted that the second connecting part 200 can also be connected to the foundation pit.

[0023] refer to Figure 2 and Figure 3 The force-applying mechanism 300 includes a first support 310, a first anchor ring 330, and a steel strand 350. The first support 310 is connected to the first connecting part 100. The first anchor ring 330 is disposed on the first support 310. One end of the steel strand 350 passes through the first anchor ring 330, and the other end of the steel strand 350 is connected to the second connecting part 200. The force-applying mechanism 300 also includes a second support 320 and a second anchor ring 340. The second support 320 is connected to the second connecting part 200. The second anchor ring 340 is disposed on the second support 320, and the other end of the steel strand 350 passes through the second anchor ring 340. It should be explained that in the construction field, an anchor ring is a component used to limit and transmit force. Its structure is usually a rigid component with a through hole. The main function of the anchor ring is to provide a stable force support point for the steel strand 350 and limit the displacement direction of the steel strand 350 during tensioning. The anchor ring allows the steel strand 350 to move in one direction. The through hole of the anchor ring is equipped with a one-way clamping component (such as a wedge block, ratchet structure or elastic retainer). When the steel strand 350 attempts to move in the opposite direction, the clamping component will automatically clamp the steel strand 350 under the reverse force of the steel strand 350, firmly restricting the steel strand 350 from retraction and preventing relative displacement between the steel strand 350 and the anchor ring. Further details will not be elaborated here.

[0024] Understandably, the first support 310 is fixedly connected to the first connecting part 100, the first anchor ring 330 is securely installed on the first support 310, the second support 320 is fixedly connected to the second connecting part 200, the second anchor ring 340 is correspondingly installed on the second support 320, and the two ends of the steel strand 350 are respectively threaded through and locked in the first anchor ring 330 and the second anchor ring 340; since both the first anchor ring 330 and the second anchor ring 340 have a one-way limiting structure (only allowing the steel strand 350 to move in the direction that allows the first connecting part 100 and the second connecting part 200 to approach each other; if the steel strand 350 attempts to rebound in the opposite direction, the locking components inside the first anchor ring 330 and the second anchor ring 340 will automatically lock the steel strand 350), when the operator applies a tensioning force to the steel strand 350, under the tensioning force of the steel strand 350 itself, the two ends of the steel strand 350 tighten in the approaching direction and will not loosen in the opposite direction, and the tension generated by the steel strand 350 will be transmitted synchronously. The tension at one end of the steel strand 350 is transmitted to the first connecting part 100 through the first anchor ring 330 and the first support 310, so that the first connecting part 100 receives tension toward the second connecting part 200; the tension at the other end of the steel strand 350 is transmitted to the second connecting part 200 through the second anchor ring 340 and the second support 320, so that the second connecting part 200 receives tension toward the first connecting part 100. The two opposing tensions at both ends of the steel strand 350 work together to finally bring the first connecting part 100 and the second connecting part 200 closer together, thereby playing a role in reinforcing the foundation 10 by limiting subsidence or closing cracks.

[0025] It should be explained that when the operator needs to apply tension to the steel strand 350, the operator can use a tensioning tool to pull one end of the steel strand 350 outward. At this time, the first anchor ring 330 allows the steel strand 350 to move, while the second anchor ring 340 clamps the other end of the steel strand 350. As the operator continues to pull, the tension force of the steel strand 350 increases, and the steel strand 350 applies a tension force to the second support 320 close to the first support 310; when the operator stops... After the steel strand 350 is pulled, the first anchor ring 330 restricts the retraction movement of the steel strand 350. At this time, the steel strand 350 applies a tension force to the first support 310 that approaches the second support 320, so that the two ends of the steel strand 350 apply a mutual tension force to the first support 310 and the second support 320 respectively, thereby causing the two ends of the steel strand 350 to apply a mutual tension force to the first connecting part 100 and the second connecting part 200 respectively through the first support 310 and the second support 320.

[0026] refer to Figure 2 and Figure 3The force-applying mechanism 300 includes multiple first anchor rings 330, multiple second anchor rings 340, and multiple steel strands 350. The multiple first anchor rings 330 are circumferentially distributed on the first support 310, and the multiple second anchor rings 340 are circumferentially distributed on the second support 320. One end of each of the multiple steel strands 350 passes through the multiple first anchor rings 330, and the other end of each of the multiple steel strands 350 passes through the multiple second anchor rings 340. It is understood that the circumferential distribution of the multiple first anchor rings 330 and second anchor rings 340 on the first support 310 and the second support 320, and the corresponding engagement of the multiple steel strands 350 with the first anchor rings 330 and second anchor rings 340, allows for a more even distribution of tension. This ensures that the contact points of the first connecting part 100, the second connecting part 200, and the connected foundation pit or foundation body 10 are subjected to more balanced forces, effectively preventing new damage to the foundation body 10 caused by excessive localized stress. On the other hand, the tension of multiple steel strands 350 can create a superimposed effect, providing a greater total tensile force output compared to a single steel strand 350. This can address scenarios where the foundation 10 shows a significant sinking trend, using stronger tension to more stably limit the sinking of the foundation 10. It can also adapt to situations where the crack width of the foundation 10 is large, using greater tension to accelerate the convergence of the two sides of the crack. As a preferred embodiment of this utility model, the force application mechanism 300 includes four first anchor rings 330, four second anchor rings 340, and four steel strands 350.

[0027] refer to Figure 2 and Figure 3The first connecting portion 100 includes a first substrate 110, and the second connecting portion 200 includes a second substrate 210. Both the first substrate 110 and the second substrate 210 are used to connect to the foundation pit or base body 10. The first substrate 110 and the second substrate 210 are connected by a force-applying mechanism 300. The first substrate 110 is provided with a plurality of first connecting holes 111, which are all used for fasteners to pass through. The second substrate 210 is provided with a plurality of second connecting holes 211, which are also used for fasteners to pass through. A first support 310 and a second support 320 are respectively provided on the first substrate 110 and the second substrate 210. Understandably, if the base 10 sinks, the operator will drill matching mounting holes at corresponding positions on the pit and the base 10, based on the multiple first connecting holes 111 on the first substrate 110 and the multiple second connecting holes 211 on the second substrate 210. Then, the first substrate 110 will be attached to the preset connecting surface of the pit, aligning the first connecting holes 111 with the mounting holes drilled in the pit. The second substrate 210 will then be attached to the preset connecting surface of the base 10, aligning the second connecting holes 211 with the mounting holes drilled in the pit. Aligning the mounting holes drilled on the foundation 10 with the first connecting hole 111, the operator then passes the fasteners through the first connecting hole 111 and the mounting holes on the pit, and through the second connecting hole 211 and the mounting holes on the foundation 10, and tightens the fasteners to securely connect the first base plate 110 and the second base plate 210 to the pit and the foundation 10, respectively. Then, the operator applies tension to the steel strand 350, causing the steel strand 350 to exert a force that brings the first base plate 110 and the second base plate 210 closer together. When the foundation 10 cracks, the installation method for the first base plate 110 and the second base plate 210 is similar and will not be described further here. In this embodiment of the invention, the fasteners are common bolts or anchors, and the second base plate 210 can also be connected to the pit.

[0028] refer to Figure 2 and Figure 3 The first connecting hole 111 is a first oblong hole, and the second connecting hole 211 is a second oblong hole. It can be understood that when the first substrate 110 is connected to the pit or base body 10 and the second substrate 210 is connected to the pit or base body 10, if there is a positional deviation in the previous drilling, the length direction of the first oblong hole and the second oblong hole allows the fastener to move within the first oblong hole and the second oblong hole, so that the installation of the first substrate 110 and the second substrate 210 can be completed without re-drilling.

[0029] refer to Figure 2 and Figure 3The first connecting portion 100 further includes a first auxiliary plate 120, and the second connecting portion 200 further includes a second auxiliary plate 220. The first auxiliary plate 120 is hinged to the side of the first substrate 110 away from the second substrate 210, so that the angle between the first auxiliary plate 120 and the first substrate 110 can be adjusted. The second auxiliary plate 220 is hinged to the side of the second substrate 210 away from the first substrate 110, so that the angle between the second auxiliary plate 220 and the second substrate 210 can be adjusted. Both the first auxiliary plate 120 and the second auxiliary plate 220 are used to connect to the pit or the base body 10. It can be understood that both the first auxiliary plate 120 and the second auxiliary plate 220 can be connected to the pit or the base body 10. When the surface of the foundation 10 or the foundation pit has uneven structures such as sharp edges, protrusions, or local tilting, the operator can adjust the bending angles of the first auxiliary plate 120 and the first base plate 110, and the second auxiliary plate 220 and the second base plate 210 according to the actual shape of the part to be connected (such as the size of the sharp edges and the angle of the surface tilt). This allows the first auxiliary plate 120 and the first base plate 110, and the second auxiliary plate 220 and the second base plate 210 to fit tightly against the surface of the foundation 10 or the foundation pit. Fasteners are then used to achieve a stable connection between the first auxiliary plate 120, the first base plate 110, the second auxiliary plate 220, and the second base plate 210 and the foundation 10 and the foundation pit. In this embodiment of the invention, the first auxiliary plate 120 is hinged to the first base plate 110 via a first hinge shaft, and the second auxiliary plate 220 is hinged to the second base plate 210 via a second hinge shaft.

[0030] refer to Figure 2 and Figure 3 The first auxiliary plate 120 has multiple third connecting holes 121, all of which are used for fasteners to pass through. The second auxiliary plate 220 has multiple fourth connecting holes 221, all of which are used for fasteners to pass through. The third connecting holes 121 are third oblong holes, and the fourth connecting holes 221 are fourth oblong holes. In this embodiment of the invention, the installation method of the first auxiliary plate 120 is the same as that of the first base plate 110, and the installation method of the second auxiliary plate 220 is the same as that of the second base plate 210. The third oblong holes serve the same function as the first oblong holes, and the fourth oblong holes serve the same function as the second oblong holes, which will not be further elaborated here.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
