Description

Technical Field

[0001] The invention relates to a supporting and protecting structure, in particular to a supporting and protecting structure for a building foundation applied in fields related to building foundations. Background Art

[0002] The supporting and protective structure used for building foundations is used to support the foundations and prevent them from collapsing, thereby ensuring the safety of the building foundations.

[0003] For example, a support and protection structure for a building foundation disclosed in patent publication number CN20966989U solves the problem that the existing construction foundation support plate is inconvenient to use, but the threaded part of its threaded rod is exposed to the outside, which is easily damaged by cement adhesion and collision, and is inconvenient to disassemble, store and transport, and is not convenient to use. On this basis, a support and protection structure for a building foundation disclosed in patent publication number CN111188343B includes a connecting head and a support plate, an adjusting rod is rotatably installed in the middle of the right end of the connecting head, a protective tube is sleeved on the outer side of the buffer sleeve, a toggle piece is welded and fixed to the outer surface of the adjusting rod, an adjusting block is installed inside the cavity, and an extension rod is welded and fixed to the right end of the adjusting block, mounting holes are reserved at the left end of the connecting head and the right end of the extension rod, and support plates are provided on the left side of the connecting head and the right side of the extension rod, a mounting block is bolted to the inner surface of the support plate, and a limiting groove is reserved on the surface of the mounting block, one end of a spring is fixed inside the limiting groove, and the other end of the spring is fixedly connected to the mounting rod. The supporting and protective structure for the building foundation can effectively prevent the threaded part from being damaged, thus ensuring the safety of use, and is convenient for disassembly, storage, transportation and use.

[0004] However, although the above-mentioned supporting and protective structure can prevent the threaded portion from being directly exposed to the outside, the extension rod is exposed to the outside, and it is difficult to store it after cement adheres to its surface, and it even brings inconvenience to the dismantling operation. Even if the extension rod can be stored inside the adjusting rod, cement dust and other particles adhered to the surface of the extension rod will remain inside the adjusting rod, making it difficult to smoothly extend the extension rod outward at a later time. Therefore, a supporting and protective structure for a building foundation is proposed to improve the above-mentioned problem. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that although the existing supporting and protective structure can prevent the threaded part from being directly exposed to the outside, the extension rod is exposed to the outside, and it is difficult to store it after cement adheres to its surface, and it even brings inconvenience to the dismantling operation. Even if the extension rod can be stored inside the adjusting rod, cement dust and other particles adhered to the surface of the extension rod will remain inside the adjusting rod, making it difficult to smoothly extend the extension rod outward at a later time.

[0006] To solve the above problems, the present invention provides a supporting and protective structure for building foundations, comprising a supporting sleeve;

[0007] A telescopic support rod, the telescopic support rod is slidably sleeved on the inner side of the support sleeve, the support sleeve is rotatably mounted with a threaded rod along its axis, the thread of the threaded rod passes through the telescopic support rod, and a limited position structure is arranged between the telescopic support rod and the support sleeve;

[0008] An adjusting component is installed between the support sleeve and the threaded rod, and the threaded rod is driven to rotate by the adjusting component, so that the telescopic support rod moves back and forth along the axis direction of the support sleeve under the limiting action of the limiting structure;

[0009] The cleaning part is installed at one end of the support sleeve away from the adjustment component. The cleaning part includes a conical ring, which is coaxially connected to the support sleeve, and the expanded end of the conical ring is arranged toward the side away from the support sleeve. The inner diameter of the expanded end of the conical ring is larger than the diameter of the telescopic support rod, and the inner diameter of the contracted end of the conical ring is consistent with the diameter of the telescopic support rod.

[0010] In the above-mentioned supporting and protecting structure for building foundation, by installing a threaded rod with threads passing through the telescopic supporting rod on the inner side of the supporting sleeve, the threaded part can be effectively prevented from being exposed to the outside, thereby ensuring the stable telescopic action of the telescopic supporting rod. By installing a conical collar at the end of the supporting sleeve, during the process of contracting the telescopic supporting rod, the conical collar can be used to gradually scrape off the thick cement, soil and other impurities attached to the surface of the telescopic supporting rod. Compared with the local one-time scraping method, the scraping method of gradually thinning from the outside to the inside has a better scraping effect.

[0011] As a further supplement to the present application, the limiting structure includes a guide slide rod installed on the inner side of the support sleeve. The guide slide rod is arranged parallel to the axis of the threaded rod and slides through the telescopic support rod to ensure that the telescopic support rod can move back and forth along the axis direction of the support sleeve under the limiting action of the guide slide rod.

[0012] As a further supplement to the present application, the cleaning part also includes an annular cutting blade, and a plurality of annular cutting blades are provided, and the diameters of the plurality of annular cutting blades are different. The plurality of annular cutting blades are fixed on the inner wall of the conical ring at equal distances along the axial direction of the conical ring; in the process of retracting the telescopic support rod, a plurality of annular cutting blades with gradually decreasing diameters can be used to scrape away impurities such as thick cement and soil attached to the surface of the telescopic support rod in a gradually thinning manner from the outside to the inside, and the scraping effect is better.

[0013] As another improvement of the present application, the cleaning part also includes a splitting blade, and a plurality of splitting blades are provided, and the plurality of splitting blades are equidistantly fixed on the inner wall side of the flared end of the conical ring; in the process of retracting the telescopic support rod, the splitting blade can axially split impurities such as cement and soil that are thicker and attached to the surface of the telescopic support rod, thereby reducing the burden of subsequent scraping.

[0014] As another improvement of the present application, saw teeth are provided at the cutting edges of the annular cutting blade and the dividing blade, which can achieve a better crushing effect on cement and soil attached to the surface of the telescopic support rod.

[0015] As another improvement of the present application, a conical collar is rotatably installed at the end of the support sleeve; when the conical collar is manually rotated, cement and soil attached to the surface of the telescopic support rod can be further broken up, and impurities such as cement and soil with tight adhesion can be better cleaned.

[0016] As a further supplement to the present application, a flexible protective sleeve is provided on the outer side of the threaded rod, and the flexible protective sleeve is fixed between the support sleeve and the telescopic support rod. Even if a small amount of impurities such as cement and soil enter the inner side of the support sleeve, it will not affect the threaded connection of the threaded rod.

[0017] As a further supplement to the present application, anti-slip discs are installed at the ends of the support sleeve and the telescopic support rod that are away from each other. The diameter of the anti-slip disc located on one side of the telescopic support rod is larger than the maximum diameter of the conical ring. When storing, the anti-slip disc can be used to cover the flared end of the conical ring for better safety.

[0018] As a further supplement to the present application, the adjustment assembly includes an adjustment portion, a first bevel gear, and a second bevel gear;

[0019] The adjusting part is vertically rotatably mounted on the supporting sleeve, the first bevel gear is coaxially fixed with the adjusting part, the second bevel gear is coaxially fixed with the threaded rod and meshes with the first bevel gear.

[0020] As a further supplement to the present application, the adjustment portion includes a rotating shaft and an operating handle;

[0021] The rotating shaft is rotatably mounted on the inner side of the supporting sleeve, the first bevel gear is coaxially fixed on the rotating shaft, one end of the rotating shaft passes through the supporting sleeve, and a cylindrical groove is provided on the end, the cylindrical end of the operating handle is sleeved on the inner side of the cylindrical groove, and a compression spring is connected between the operating handle and the cylindrical groove;

[0022] A positioning groove is provided at the bottom of the cylindrical groove, and a positioning block is integrally provided at the end of the operating handle located on the inner side of the cylindrical groove. The positioning block is adapted to the positioning groove, and the positioning block is non-cylindrical; through the coordinated setting of the positioning groove, the positioning block and the compression spring, when it is necessary to adjust the length of the telescopic support rod extending out of the outside of the support sleeve, it is necessary to manually press the operating handle toward one side of the rotating shaft so that the positioning block is inserted into the positioning groove, and the operating handle is rotated while maintaining the pressing action, at this time, the threaded rod can be driven to rotate, thereby adjusting the length of the telescopic support rod extending out of the outside of the support sleeve; after releasing the operating handle, the operating handle is reset under the action of the compression spring, so that the positioning block is disengaged from the positioning groove, so that the support protection structure is not easy to loosen due to accidental external collision in the supporting state.

[0023] In summary, by installing a threaded rod with threads passing through the telescopic support rod on the inner side of the support sleeve, the threaded part can be effectively avoided from being exposed to the outside, thereby ensuring the stable telescopic action of the telescopic support rod. By installing a conical collar at the end of the support sleeve, in the process of retracting the telescopic support rod, the splitting blade is first used to axially split the thick cement, soil and other impurities attached to the surface of the telescopic support rod, thereby reducing the burden of subsequent scraping. Then, a plurality of annular cutting blades with gradually decreasing diameters are used to scrape the thick cement, soil and other impurities attached to the surface of the telescopic support rod from the outside to the inside. Compared with the local one-time scraping method, the scraping method of gradually thinning from the outside to the inside has a better scraping effect. For impurities such as cement and soil with tight adhesion, the conical collar can be manually rotated, and the saw teeth set at the cutting edges of the annular cutting blade and the splitting blade can be used to further break the cement and soil attached to the surface of the telescopic support rod.

[0034] The following is a detailed description of four implementation methods of the present application in conjunction with the accompanying drawings.

[0035] The first implementation method:

[0036] The present invention provides a supporting and protective structure for building foundations, see Figure 1-6 , a supporting sleeve 1, a telescopic supporting rod 2, an adjusting component 5 and a cleaning part 8.

[0037] Among them, the telescopic support rod 2 is slidably sleeved on the inner side of the support sleeve 1, and the support sleeve 1 is rotatably installed with a threaded rod 3 along its axis. The threaded rod 3 threadably penetrates the telescopic support rod 2, and a limiting structure is arranged between the telescopic support rod 2 and the support sleeve 1. Specifically, the limiting structure includes a guide slide bar 4 installed on the inner side of the support sleeve 1. The guide slide bar 4 is arranged parallel to the axis of the threaded rod 3 and slides through the telescopic support rod 2, ensuring that the telescopic support rod 2 can reciprocate along the axis direction of the support sleeve 1 under the limiting action of the guide slide bar 4.

[0038] Among them, the adjusting component 5 is installed between the supporting sleeve 1 and the threaded rod 3, and the threaded rod 3 is driven to rotate by the adjusting component 5, so that the telescopic supporting rod 2 moves back and forth along the axial direction of the supporting sleeve 1 under the limiting action of the limiting structure. Specifically, the adjusting component 5 includes an adjusting part 51, a first bevel gear 52 and a second bevel gear 53. The adjusting part 51 is vertically rotatably installed on the supporting sleeve 1, the first bevel gear 52 is coaxially fixed with the adjusting part 51, and the second bevel gear 53 is coaxially fixed with the threaded rod 3 and meshes with the first bevel gear 52.

[0039] In order to facilitate the disassembly and assembly of the supporting and protective structure while ensuring its stable supporting function, the adjusting part 51 includes a rotating shaft 511 and an operating handle 512. The rotating shaft 511 is rotatably installed on the inner side of the supporting sleeve 1. The first bevel gear 52 is coaxially fixed on the rotating shaft 511. One end of the rotating shaft 511 passes through the supporting sleeve 1, and a cylindrical groove 516 is provided at the end. The cylindrical end of the operating handle 512 is sleeved on the inner side of the cylindrical groove 516, and a compression spring 515 is connected between the operating handle 512 and the cylindrical groove 516. A positioning groove 513 is provided at the bottom of the cylindrical groove 516. A positioning block 514 is integrally provided at the end of the operating handle 512 located on the inner side of the cylindrical groove 516. The positioning block 514 is adapted to the positioning groove 513, and the positioning block 514 is non-cylindrical.

[0040] The supporting and protective structure for the building foundation is arranged through the coordination of the positioning groove 513, the positioning block 514 and the compression spring 515. When it is necessary to adjust the length of the telescopic support rod 2 extending out of the outside of the support sleeve 1, it is necessary to manually press the operating handle 512 toward one side of the rotating shaft 511 so that the positioning block 514 is inserted into the positioning groove 513, and the operating handle 512 is rotated while maintaining the pressing action. At this time, the threaded rod 3 can be driven to rotate, thereby adjusting the length of the telescopic support rod 2 extending out of the outside of the support sleeve 1; after releasing the operating handle 512, the operating handle 512 is reset under the action of the compression spring 515, so that the positioning block 514 is disengaged from the positioning groove 513, so that the supporting and protective structure is not easy to loosen due to accidental external collision in the supporting state.

[0041] The supporting and protective structure for building foundation can effectively prevent the threaded part from being exposed to the outside by installing a threaded rod 3 that threads through the telescopic supporting rod 2 on the inner side of the supporting sleeve 1, thereby ensuring the stable telescopic action of the telescopic supporting rod 2.

[0042] Among them, the cleaning part 8 is installed at one end of the support sleeve 1 away from the adjustment component 5, and the cleaning part 8 includes a conical ring 81, the conical ring 81 is coaxially connected to the support sleeve 1, and the flared end of the conical ring 81 is set toward the side away from the support sleeve 1, the inner diameter of the flared end of the conical ring 81 is larger than the diameter of the telescopic support rod 2, and the inner diameter of the contracted end of the conical ring 81 is consistent with the diameter of the telescopic support rod 2.

[0043] The cleaning portion 8 further comprises an annular cutting blade 82 , of which a plurality of annular cutting blades 82 are provided, and the diameters of the plurality of annular cutting blades 82 are different. The plurality of annular cutting blades 82 are fixed on the inner wall of the conical collar 81 at equal distances along the axial direction of the conical collar 81 .

[0044] The supporting and protective structure for the building foundation is provided with a conical collar 81 installed at the end of the supporting sleeve 1. During the process of retracting the telescopic supporting rod 2, multiple annular cutting blades 82 with gradually decreasing diameters on the inner side of the conical collar 81 can be used to scrape away thick impurities such as cement and soil attached to the surface of the telescopic supporting rod 2 in a gradually thinning manner from the outside to the inside. Compared with a local one-time scraping method, the scraping method of gradually thinning from the outside to the inside has a better scraping effect.

[0045] Among them, the outer side of the threaded rod 3 is provided with a flexible protective sleeve 6, and the flexible protective sleeve 6 is fixed between the support sleeve 1 and the telescopic support rod 2. Even if a small amount of impurities such as cement and soil enter the inner side of the support sleeve 1, it will not affect the threaded connection function of the threaded rod 3.

[0046] Among them, the ends of the support sleeve 1 and the telescopic support rod 2 that are away from each other are both installed with anti-skid plates 7, and the diameter of the anti-skid plate 7 located on one side of the telescopic support rod 2 is larger than the maximum diameter of the conical ring 81; when storing, the anti-skid plate 7 can be used to cover the flared end of the conical ring 81, which is safer.

[0047] Working principle: During installation, manually press the operating handle 512 toward one side of the rotating shaft 511 so that the positioning block 514 is inserted into the positioning groove 513, and keep the pressing action while turning the operating handle 512. At this time, the threaded rod 3 can be driven to rotate, thereby adjusting the length of the telescopic support rod 2 extending out of the outside of the support sleeve 1. According to conventional operations, the L-shaped support plate is attached to the side wall of the foundation pit, and the L-shaped support plates on the opposite sides of the foundation pit are supported by the support protection structure. After the support is completed, release the operating handle 512, and the operating handle 512 is reset under the action of the compression spring 515, so that the positioning block 514 is disengaged from the positioning groove 513, so that the support protection structure is not easy to loosen due to accidental external collision in the supporting state;

[0048] During disassembly, the operating handle 512 is manually pressed toward one side of the rotating shaft 511 so that the positioning block 514 is inserted into the positioning groove 513, and the operating handle 512 is rotated in the opposite direction while maintaining the pressing action to retract the telescopic support rod 2. During the process of retracting the telescopic support rod 2, multiple annular cutting blades 82 with gradually decreasing diameters are used to scrape away impurities such as thick cement and soil attached to the surface of the telescopic support rod 2 in a gradually thinning manner from the outside to the inside.

[0049] Second implementation method:

[0050] Based on Implementation 1, this implementation adds the following structure, so that this application has a better cleaning effect, and the specific configuration is as follows: Figure 7As shown, the cleaning portion 8 further includes a splitting blade 83 , and a plurality of splitting blades 83 are provided, and the plurality of splitting blades 83 are fixed at equal intervals on the inner wall circumference of the expanded end of the conical collar 81 .

[0051] During the process of retracting the telescopic support rod 2, the segmentation blade 83 can axially segment the thick impurities such as cement and soil attached to the surface of the telescopic support rod 2, thereby reducing the burden of subsequent scraping.

[0052] The third implementation method:

[0053] This embodiment is based on the embodiment 2. Figure 8 As shown, the cutting edges of the annular cutting blade 82 and the dividing blade 83 are both provided with saw teeth 84 , which can achieve a better crushing effect on cement and soil attached to the surface of the telescopic support rod 2 .

[0054] The fourth implementation method:

[0055] In this embodiment, based on embodiment 3, a conical collar 81 is rotatably mounted on the end of the support sleeve 1. When the conical collar 81 is manually rotated, cement and soil attached to the surface of the telescopic support rod 2 can be further broken up, and impurities such as cement and soil with tight adhesion can be better cleaned.

[0056] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
