Description

Technical Field

[0001] This application relates to the field of anchor structure technology in geotechnical anchoring engineering, and in particular to a load-bearing shell and an anchor. Background Technology

[0002] In geotechnical anchoring engineering, anchor bolts, as important load-bearing components, are widely used in anti-buoyancy, slope protection, foundation pit reinforcement, tunnel engineering, and other fields. The load-bearing body in the anchor bolt is installed at the bottom end and / or lower part of the anchor bolt body and is embedded in the grout within the anchor hole. It is one of the main load-bearing components of the anchor bolt.

[0003] However, in existing technologies, the bearing is usually directly buried in the grouting body, and the entire outer surface of the bearing is in direct contact with the grouting body. The anchor bolts usually do not have a protective structure against groundwater and soil corrosion, which makes the existing bearings susceptible to corrosion.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0045] Beneficial Effects: This application discloses a carrier shell and anchor rod. Two shells are spliced ​​and fixed together by a locking mechanism, forming a cavity. One end of the cavity is open, forming a bearing port. After the two shells are spliced, the carrier is enclosed within the cavity. The carrier with the shell is then installed on the anchor rod and placed into the anchor hole. The bearing surface of the carrier contacts the grouting material inside the anchor hole through the bearing port and transmits pressure. The anchor rod, connected to the carrier, extends out of the cavity through the bearing port. The outer wall and bottom of the carrier are protected by the shells on both sides, thus resisting corrosion from groundwater, soil, and stray currents, effectively slowing down the corrosion of the carrier. The carrier shell also provides a structure for easy connection and positioning with external auxiliary components, facilitating the connection of external auxiliary components and enhancing the functional expansion capabilities of the anchor rod.

[0065] To make the objectives, technical solutions, and advantages of this application clearer and more explicit, the following detailed description of this application is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0066] In existing anchor bolts, the outer surface of the load-bearing body is exposed without a protective shell. This lack of protection against groundwater and soil corrosion, coupled with the absence of a convenient installation structure for connection and positioning with other external components, addresses these issues. Therefore, this application proposes the following embodiments to solve these problems.

[0067] Example 1

[0068] like Figure 1 , Figure 2 As shown, this embodiment proposes a carrier shell 10 for enclosing the carrier 20 and installing it on the anchor rod 30, placing it in the grouting body 71 within the anchor hole 70. The bearing surface 22 of the carrier 20 contacts the grouting body 71 through the bearing port 111 and transmits pressure. For ease of structural description, the structure is described using the example of the carrier 20 being vertically positioned in the anchor hole. The axis of the carrier 20 is located in the up-down direction, and the radial direction of the carrier 20 is the left-right direction. The following descriptions will use this as a reference for directional structural descriptions.

[0069] like Figure 1 , Figure 2As shown, the outer shell 10 of the carrier mainly includes: two splicable shells 100 and locking parts 200. Each shell 100 is semi-cylindrical, and locking parts 200 are fixed at the upper left, upper right and lower ends of each shell 100. The locking parts 200 are respectively arranged opposite to each other on the two shells 100, so as to splice and fix the two shells 100. After the two shells 100 are spliced ​​and fixed, a cavity 110 is formed inside, and the upper part of the cavity 110 is open to form a bearing opening 111. The cavity 110 is used to enclose and accommodate the carrier 20, and the carrier 20 can be connected and fixed to the shell 100 within the cavity 110. The upward-facing surface of the carrier 20 is the bearing surface 22, which is located within the bearing opening 111 of the cavity 110. This allows the anchor rod 30 connected to the carrier 20 to pass through the bearing opening 111 and exit the cavity 110. In this embodiment, the ratio of the diameter of the bearing opening 111 to the diameter of the bearing surface 22 is 0.8-1.05, allowing the bearing surface 22 to be exposed through the bearing opening 111 and to contact the grouting body 71 to transmit pressure, thus realizing its anchor rod bearing function. The outer wall and bottom of the carrier 20 are protected by the shell 100, thereby resisting groundwater and soil corrosion. When the shell 100 is made of metal, it can also shield stray currents, effectively slowing down the corrosion of the carrier 20.

[0070] like Figure 1 (a) Figure Figure 2 As shown, in this embodiment, both shell pieces 100 include a shell body 120 and a shell tail 130. The shell body 120 is located above the shell tail 130, and the bearing port 111 is located above the shell body 120. After the two shell pieces 100 are spliced ​​and fixed by the locking part 200, the two shell body parts 120 are spliced ​​to form a cylindrical outer wall, and the two shell tail parts 130 are spliced ​​to form a conical outer wall. Thus, the shape of the carrier shell 10 is cylindrical at the top and conical at the bottom. The upper part of the cavity 110 is a cylindrical space, and the lower part of the cavity 110 is a conical space. The cylindrical space enclosed by the upper shell portion 120 encloses and accommodates the support body 20. Specifically, the support body 20 comprises a support plate 21 and a fixing portion 23 (anchor). The support plate 21 and the fixing portion 23 are integrated. The upper surface of the support plate 21 forms a support surface 22. The anchor rod 30 penetrates the support plate 21 from top to bottom. The fixing portion 23 is located below the support plate 21, fixing the support plate 21 to the anchor rod 30 via the fixing portion 23. The anchor rod 30 uses threaded steel bars for prestressed concrete, and the fixing portion 23 (anchor) is an anchoring nut that matches the anchor rod 30. Both the support plate 21 and the fixing part 23 are located in the cavity 110. The inner walls of the shell parts 120 on the left and right sides are clamping surfaces 121. The side walls of the support plate 21 are clamped by the clamping surfaces 121 of the shell parts 120 on the left and right sides, so that the support body 20 is installed in the cavity 110 of the spliced ​​shell 100.

[0071] The two shell tails 130 are spliced ​​together to form a conical outer wall, making the overall structure larger at the top and smaller at the bottom. During the process of inserting the anchor rod into the anchor hole, the conical outer wall at the front end can guide the insertion process and reduce the resistance of the bearing body 20 during the insertion into the anchor hole.

[0072] like Figure 1 (a) Figure Figure 2 As shown, the bearing port 111 at the upper end of the cavity 110 is located above the bearing surface 22 of the carrier 20. A connecting positioning part 300 is provided on the edge of the bearing port 111, which is used to position the carrier 20. In this embodiment, the connecting positioning part 300 is a radial spoke 310. The radial spoke 310 is provided on the edge of the upper end of the shell part 120 and extends radially inward for a predetermined length. The inner diameter of the radial spoke 310 is smaller than the outer diameter of the bearing surface 22. The hollow space enclosed by the radial spokes 310 on both sides is the bearing port 111. The inner diameter of the bearing port 111 enclosed by the radial spokes 310 is 120mm. The bearing plate 21 is a circular steel plate with a central through hole. The outer diameter of the bearing plate 21 is 130mm and the thickness is 20mm. By abutting the radial spokes 310 against the upper surface of the bearing surface 22, the housings 100 on both sides can be positioned and mounted on the bearing plate 21. The radial spokes 310 constrain the sliding of the bearing plate 21 and prevent the bearing 20 from detaching from the bearing housing 10.

[0073] like Figure 1 Chinese (b) map Figure 2 As shown, the anchor rod 30 is inserted into the cavity 110 through the bearing port 111 and connected to the bearing body 20, assembling into an anchor rod assembly including the anchor rod 30, the bearing body 20 and the bearing body shell 10. The assembly is placed into the anchor hole 70, and the anchor hole 70 is filled with cement grout to form a grouting body 71. The bearing surface 22 of the bearing plate 21 contacts the grouting body 71 through the bearing port 111 and transmits pressure to provide pull-out resistance for the anchor rod 30.

[0074] like Figure 1 (a) Figure Figure 2 As shown, each locking part 200 on each housing 100 includes a first locking member 210 and a second locking member 220. The first locking member 210 is located above the housing 100, and the second locking member 220 is located below the housing 100. The two housings 100 are spliced ​​and fixed by the cooperation of the first locking member 210 and the second locking member 220.

[0075] like Figure 1 (a) Figure Figure 2As shown, in this embodiment, each shell 100 has connecting ear plates 230 fixed on its left and right sides respectively. The first locking fastener 210 includes a first bolt hole 211. First bolt holes 211 are opened on both the left and right connecting ear plates 230. The first bolt holes 211 on the two shells 100 are correspondingly arranged. Fasteners 212 (bolts) are inserted into the first bolt holes 211 on both sides of the shells 100 to fix the upper parts of the two shells 100 together. In this embodiment, each shell 100 has a connecting ear plate 230 at its lower bottom. The second locking fastener 220 includes a second bolt hole 221. The second bolt holes 221 are correspondingly opened on both shells 100. Fasteners 212 (bolts) are inserted into the second bolt holes 221 on both sides to fix the lower parts of the two shells 100 together. The two shells 100 are spliced ​​and locked together to form the carrier shell 10 by using bolt holes and bolts to cooperate.

[0076] like Figure 3 As shown, further, based on the above structure, an arc-shaped surrounding plate 311 is provided on the inner edge of the radial spoke 310 along the axial direction of the anchor rod body 30. The arc-shaped surrounding plate 311 extends upward to a predetermined length to form a cylindrical shell, and the upper opening of the cylindrical shell forms a bearing port 111. The first locking fastener 210 is provided on the arc-shaped surrounding plate 311, so that the connecting lug 230 at the upper end of the housing 100 and the first locking fastener 210 are both located within the range of the planar projection of the outer wall edge of the bearing housing 10, so that the locking part 200 will not protrude radially outward along the housing 100. When designing the anchor bolt hole diameter, it is not necessary to increase the anchor hole diameter due to the outward protrusion of the locking part 200, thus optimizing the structural design.

[0077] Example 2

[0078] like Figure 4 As shown, the structure of the connecting positioning part 300 in this embodiment is different from that in Embodiment 1. The connecting positioning part 300 in this embodiment is a positioning vertical plate 320 provided on two shells 100. The positioning vertical plate 320 is located at the edge of the bearing port 111 and extends downward. The positioning vertical plate 320 can be parallel to the inner wall of the upper part of the shell 100. When the bearing 20 is placed in the cavity 110, the lower end of the positioning vertical plate 320 abuts against the upper surface of the bearing surface 22 to position the bearing 20, so that the two shells 100 constrain the sliding of the bearing plate 21 and prevent the bearing 20 from detaching from the bearing shell 10.

[0079] Example 3

[0080] like Figure 5 , Figure 6As shown, the connection positioning part 300 in this embodiment is used for the connection and positioning of the support body 20 and the external auxiliary component, which is a reinforcing cage 40. The reinforcing cage 40 consists of longitudinal bars 43, stirrups 44, and a base 45, and the diameter of the reinforcing cage 40 is 110mm. The longitudinal bars 43 and stirrups 44 are fixed on the base 45, and the base 45 of the reinforcing cage 40 is an inverted T-shaped cylinder with a flange 41, the diameter of which is 130mm.

[0081] like Figure 5 As shown, during installation, the flange 41 of the reinforcing cage 40 is secured between the bearing plate 21 and the radial spokes 310. The inner wall of the outer shell 10 of the bearing body clamps the flange 41 and the outer wall of the bearing body 20. The bearing surface 22 of the bearing plate 21 abuts against the bottom surface of the flange 41, and the bottom surface of the radial spokes 310 abuts against the upper surface of the flange 41. The reinforcing cage 40 and the bearing body 20 are fixedly connected through the outer shell 10. The reinforcing cage 40 causes the cement grout in front of the bearing body 20 to form a reinforced cement-aggregate body, thereby increasing the strength of the grout and enhancing the pull-out resistance and stability of the anchor bolt.

[0082] It should be noted that in this embodiment, an arc-shaped surrounding plate 311 can still be provided on the inner edge of the radial spoke 310 along the axial direction of the anchor rod body 30, which can also achieve the function of optimizing the structural design.

[0083] like Figure 7 As shown, furthermore, a bladder 50 is provided around the outer periphery of the aforementioned reinforcing cage 40. The bladder 50 is made of a soft material that is impermeable or only slightly permeable. The bladder 50 has an upper opening and a lower opening. The anchor rod 30 and the reinforcing cage 40 are inserted into the bladder 50. The lower opening of the bladder 50 is clamped between the side wall of the bearing plate 21 and the inner side wall of the bearing shell 10 to achieve a compression seal. The upper opening of the bladder 50 has a grouting hole and a vent hole, which are sealed by a sealing component. The bladder 50 and the bearing shell 10 seal and surround the reinforcing cage 40 and the bearing body 20. After being placed underground, grout is injected into the bladder 50 through the grouting hole. The bladder 50 prevents groundwater and soil from mixing with the grout inside, ensuring the purity of the cement grout inside the bladder 50, controlling the water-cement ratio, ensuring the quality of the grout, and improving the reliability of the anchor rod.

[0084] Example 4

[0085] like Figure 8 , Figure 9As shown, in this embodiment, the structure of the connecting positioning part 300 is modified based on embodiment three. The connecting positioning part 300 is a socket 330, which is respectively opened on the two shells 100. The socket 330 is used for the insertion of the plug 42 of the external auxiliary component, and the external auxiliary component is positioned against the bearing surface 22. In the specific structure, taking the external auxiliary component as a steel cage 40 as an example, the socket 330 is opened on the two shells 100 respectively, and the plug 42 protrudes outward from the base of the steel cage 40. During installation, the plug 42 is inserted into the socket 330, and the upper surface of the bearing plate 21 abuts against the base of the steel cage 40 to prevent the bearing body 20 and the steel cage 40 from sliding off the bearing body shell 10.

[0086] Furthermore, such as Figure 10 As shown, a bag 50 is also installed on the outer periphery of the steel cage 40. The plug 42 matches the socket 330, so that the plug 42 and the cloth of the bag wall of the bag 50 are inserted into the socket 330 and can just fill the socket 330, thereby improving the interlocking of the fixed connection.

[0087] Example 5

[0088] like Figure 11 , Figure 12 , Figure 13 As shown, in this embodiment, the connecting positioning part 300 consists of two hanging ears 340 located at the upper left and upper right ends of the two shells 100, and the external auxiliary component is a piling pipe 60. A hook 61 is provided on the piling pipe 60. The hook 61 on the outer wall of the piling pipe 60 hooks onto the hanging ears 340. The piling machine lifts the anchor assembly, which includes the bearing body 20, the bearing body shell 10, and the anchor rod body 30, through the piling pipe 60. After aligning with the construction point, the piling pipe 60 applies downward force, causing the hook 61 and the hanging ears 340 to disengage. The piling pipe 60 continues to apply downward force, and the lower end face of the piling pipe 60 presses against the bearing surface 22 of the bearing plate 21. After inserting the anchor assembly into the designed depth in the stratum, the piling pipe 60 is pulled out, leaving the bearing body 20, the bearing body shell 10, and the anchor rod body 30 in the stratum. Cement grout is then injected into the anchor hole to form a grouting body. The process employs a soil displacement drilling technique, which produces no debris or mud throughout the entire process. It is suitable for soil, sand, and gravel strata, and offers fast construction efficiency, energy saving, and environmental protection.

[0089] like Figure 13 As shown in Figure (c), the bearing body 20 and the reinforcing cage 40 are installed together on the anchor rod body 30 through the outer shell 10. The hook 61 on the outer wall of the piling pipe 60 hooks the hanging ear 340. After the installed anchor rod assembly is lifted and aligned with the construction point, the anchor rod assembly is inserted into the stratum. Figure 13 As shown in Figure (d), a bag 50 is also provided around the outer periphery of the steel cage 40.

[0090] Example 6

[0091] like Figure 14 As shown, the main difference between this embodiment and the previous embodiment lies in the structure of the locking part 200. In this embodiment, the locking part 200 is a snap fastener or a binding wire. The snap fastener can be a pin. Specifically, each housing 100 has connecting ear plates 230 fixed to its upper left and right sides respectively. The connecting ear plates 230 have through holes. The first locking component 210 includes a first snap fastener 213 (snap fastener). The snap fasteners on the left and right sides are inserted into the through holes to secure the upper parts of the two housings 100. Similarly, the lower second locking component 220 can also use a second snap fastener 222 (snap fastener), and the bottoms of the two housings 100 are secured by snap fasteners.

[0093] like Figure 15 As shown, the main difference between this embodiment and the previous embodiment lies in the structure of the locking part 200. In this embodiment, the locking part 200 at the upper end of the carrier shell 10 is a hose clamp groove. Specifically, each shell 100 has a corresponding first hose clamp groove 214 on its upper part. A catch 216 is provided at the upper end of the circular shell 100, and the first hose clamp groove 214 is formed below the catch 216. The hose clamp 215 is engaged in the first hose clamp groove 214 to clamp the two shells 100 together, thereby binding and fixing the upper parts of the two shells 100. The first hose clamp groove 214 formed below the catch prevents the hose clamp from sliding off. The lower part of the carrier shell 10 is fixed by engaging with bolts through the second bolt hole 221.

[0094] It is easy to imagine that in another structure (not shown in the figure), the lower second locking fastener 220 can also adopt a second hose clamp groove, in which the hose clamp is engaged to clamp the lower parts of the two housings 100.

[0095] It should be noted that, in the scheme of this application, the first locking component 210 can be any one or more of the first bolt hole 211, the first snap fastener 213, and the first hose clamp groove 214. The second locking component 220 can be any one or more of the second bolt hole 221, the second snap fastener 222, and the second hose clamp groove. They can be combined to achieve stable fixation of the two housings 100.

[0096] Example 8

[0097] like Figure 16As shown in Figures (e) and (f), in this embodiment, the outer shell 10 of the carrier body 10 can be disposed on the carrier body 20 at the tail of the anchor rod 30, as described above. Therefore, based on the above embodiment, the lower part of the outer shell 10 of the carrier body 10 in this embodiment also has a rod opening 112, which communicates with the cavity 110. The rod opening 112 and the carrier opening 111 are located at opposite upper and lower ends of the cavity 110, respectively, and the anchor rod 30 can pass through the rod opening 112.

[0098] like Figure 16 Figure (e) in the middle and Figure 17 As shown, correspondingly, the second locking fasteners 220 are provided on the housing 100 on both radial sides of the rod opening 112. For example, first locking fasteners 210 are respectively provided at the upper left and upper right ends of the two housings 100. The two upper first locking fasteners 210 are first bolt holes 211, which are located on the left and right sides of the bearing opening 111, respectively. The first bolt holes 211 are formed on the connecting ear plate 230, and bolts are used to screw and fix the upper parts of the two housings 100 through the first bolt holes 211 on the left and right sides of the upper part of the housing 100. Second locking fasteners 220 are respectively provided at the lower left and lower right ends of the two housings 100. The two lower second locking fasteners 220 are second bolt holes 221, which are located on the left and right sides of the rod opening 112, respectively. The second bolt holes 221 are formed on the connecting ear plate 230, and bolts are used to screw and fix the lower parts of the two housings 100 through the second bolt holes 221 on the left and right sides of the lower part of the housing 100, respectively. In this embodiment, the carrier 20 and the carrier shell 10 are installed in the middle section of the anchor rod 30. The anchor rod 30 is inserted into the carrier 20 through the bearing port 111 and passes through the rod port 112 below the carrier shell 10. Multiple carriers 20 and carrier shells 10 can be installed on one anchor rod 30 to form a distributed carrier anchor. The load of the anchor is shared by multiple carriers 20 to avoid damage caused by excessive load on a single carrier 20.

[0099] Example 9

The anchor bolt also includes a bearing body shell 10 as described in the above embodiment, with two shells 100 spliced ​​and sandwiched around the outer periphery of the bearing body 20. The anchor bolt body 30 passes through the bearing port 111 and connects to the bearing body 20, and the two shells 100 are fixedly connected by a locking part 200.

[0101] One bearing body 20 can be set at the bottom of the anchor rod body 30. In this way, only the bearing body shell 10 with the bearing port 111 at the upper end needs to be installed on the bearing body 20, and the lower end of the bearing body shell 10 is closed.

[0102] like Figure 16 , Figure 17 As shown, in another structure, multiple bearing bodies 20 are provided on the anchor rod body 30, and the multiple bearing bodies 20 are axially spaced on the anchor rod body 30. Multiple bearing body shells 10 are correspondingly provided and respectively fitted onto the bearing bodies 20. Referring to the structure in Embodiment Eight, the upper part of the bearing body shell 10 has a bearing opening 111, and the lower part has a rod opening 112. Multiple bearing bodies 20 and bearing body shells 10 can be installed on a single anchor rod body 30, and the load of the anchor rod is shared by multiple bearing bodies 20, avoiding excessive load on a single bearing body 20 that could cause damage.

[0103] like Figure 18 As shown, in another structure, the difference from the above embodiment lies in the structure of the anchor rod 30. In this embodiment, the anchor rod 30 is a steel strand, and the fixing part 23 (anchor) of the bearing 20 is an anchor that matches the steel strand. The steel strand is fixedly connected to the fixing part 23 (anchor) by clamping with clips or by compression locking.
