Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to an anchor rod device. Background Art

[0002] Currently, spliced ​​anchors have emerged to facilitate storage, transportation, handling, and the creation of suitable lengths. Existing spliced ​​anchors are typically composed of a backing plate, a nut, and several steel bars. Each bar has a screw connection and a screw hole at its head and tail ends, and the bars are serially connected together through the corresponding screw connections and screw holes (for example, as disclosed in Chinese patent application publication number CN107227969A).

[0003] Among them, in order to ensure the strength and anchoring strength of the spliced ​​anchor rod itself, the overall length of the spliced ​​anchor rod is mostly more than 3 meters, and the diameter of the steel bar is more than 32 mm. Although this can effectively improve the relevant strength, it will cause the overall weight of the spliced ​​anchor rod to be more than 12 pounds. Therefore, the overall weight of the existing spliced ​​anchor rod is relatively large, which will cause the workers to place the spliced ​​anchor rod very laborious. This will not only lead to a relatively high labor intensity for the workers, but also lead to a relatively low efficiency in the placement of the spliced ​​anchor rod. In addition, in the projects that currently require anchor rod reinforcement, a large number of anchor rods are generally set up for reinforcement, which will seriously affect the construction efficiency of the related projects.

[0004] Therefore, it is very necessary to design an anchor rod device with a cold-pressed friction-pressed connector to solve the above technical problems. Utility Model Content

[0008] Preferably, the sleeve is buckled onto the fiberglass rod or the fiberglass rod is fixed by grouting inside the sleeve.

[0009] Preferably, the length of the sleeve is greater than the length of the screw sleeve.

[0010] Preferably, the length of the sleeve is more than five times greater than the length of the threaded sleeve.

[0015] Preferably, the length of the sleeve tube is greater than the length of the threaded tube.

[0016] Preferably, the length of the sleeve tube is more than five times greater than that of the threaded tube.

[0017] The beneficial effects of the present invention are as follows: the anchor rod device adopts a fiberglass rod, wherein under the same specifications (diameter and length specifications), the weight of the fiberglass rod is much lighter than that of the steel bar, and the tensile strength of the fiberglass rod is also higher than that of the steel bar, so that the overall weight of the anchor rod can be greatly reduced while ensuring the structural strength, which can make the placement process of the workers very convenient, which can not only greatly reduce the labor intensity of the workers, but also improve the placement efficiency of the anchor rod, and can greatly improve the construction efficiency of related projects.

[0024] like Figure 1 and Figure 2 As shown, the utility model describes an anchor rod device with cold-pressed friction-pressed connector connection, comprising N connectors 1 and N+1 fiberglass rods 2, wherein N represents the number of connectors 1, and N is greater than or equal to 1. The connector 1 comprises a connecting screw 11 and two connecting rod bodies 12, and the connecting rod body 12 comprises a sleeve tube 121 and a screw tube 122. One end of the screw tube 122 is friction-welded to one end of the sleeve tube 121, and the screw tubes 122 of the two connecting rod bodies 12 are respectively screwed to the two ends of the connecting screw 11; the fiberglass rods 2 are arranged side by side, and a connector 1 is arranged between each adjacent fiberglass rod 2, and the ends of the adjacent fiberglass rods 2 are respectively sleeved in the two sleeve tubes 121 of the connector 1.

[0025] A fiberglass rod 2 is used in the anchor rod device. Under the same specifications (diameter and length specifications), the weight of the fiberglass rod 2 is much lighter than that of the steel bar, and the tensile strength of the fiberglass rod 2 is also higher than that of the steel bar. In this way, the overall weight of the anchor rod can be greatly reduced while ensuring the structural strength, which makes the placement process of the workers very convenient. This not only greatly reduces the labor intensity of the workers, but also improves the placement efficiency of the anchor rod, and can greatly improve the construction efficiency of related projects.

[0026] The anchor device adopts a connector 1 to connect the glass fiber rod 2, and the connector 1 includes a connecting screw 11 and two connecting rod bodies 12. The connecting rod body 12 includes a sleeve tube 121 and a screw tube 122. One end of the screw tube 122 is friction-welded with one end of the sleeve tube 121, and the ends of the adjacent glass fiber rods 2 are respectively sleeved in the two sleeve tubes 121 of the connector 1; in this way, the sleeve tube 121 and the screw tube 122 can be sleeved to achieve strong sleeve connection and strong screw connection, respectively, so that the sleeve tube 121 and the screw tube 122 can be sleeved to achieve strong sleeve connection. Its own material, which can facilitate the connection between the sleeve 121 and the fiberglass rod 2, and the connection between the screw pipe 122 and the connecting screw 11 to be in a very good state; coupled with the screw pipe 122 and the sleeve 121 are friction welded together, which not only ensures that the assembly efficiency is very high, but also ensures that the connection between the screw pipe 122 and the sleeve 121 is very stable and reliable; such a structure can help make the connector 1 have a very stable and reliable connection strength, which can not only help control the manufacturing difficulty and manufacturing cost of the anchor device, but also ensure that the anchor device has a very high reliability.

[0027] Since the two ends of the connecting rod body 12 are used for sleeve connection and screw connection respectively, the structural strength required at the two ends of the connecting rod body 12 is different, and the structural strength required at one end is high and the structural strength required at the other end is low. When the connecting rod body adopts an integrated rod body, in order to ensure that both ends have high connection strength, the material can only be selected according to the end with high strength requirement. Only in this way can both ends of the connecting rod body 12 meet the normal connection requirements. However, the existing high-strength materials often have the problems of high processing difficulty and high manufacturing cost. In the present invention, the connecting rod body 12 adopts a structure in which the sleeve tube 121 and the screw tube 122 are friction-welded together. This can facilitate the selection of materials for the two ends of the connecting rod body 12 according to their own connection requirements, so that there is no need to select high-strength materials for both ends, which can help control the manufacturing difficulty and manufacturing cost of the anchor rod device, and can also ensure that the anchor rod device has very high reliability.

[0028] The anchor rod device is connected to the fiberglass rod 2 via the connector 1, so that the anchor rod device can also form a spliced ​​anchor rod, which can also be conveniently stored, transported, and handled, and can be spliced ​​into anchor rods of appropriate length, so the applicability of the anchor rod device is very strong.

[0029] The use of the connecting screw 11 can facilitate the two connecting rod bodies 12 of the connector 1 to adopt the same structure, which not only facilitates the mass production of the connector 1, but also facilitates storage and management, and can be easily selected during docking, which can have better applicability.

[0030] During the actual manufacturing process, when the required length of the sleeve 121 changes, it is only necessary to cut the sleeve 121 of the required length from the pipe, and then use friction welding to quickly assemble the required connecting rod body 12 without redesigning and producing the entire connecting rod body 12. This can greatly improve the efficiency of the update, and such an anchor rod device can have better applicability.

[0031] On the connecting rod body 12, in different anchoring environments, the sleeve 121 and the screw pipe 122 of appropriate length and hardness can be quickly selected according to needs, and the selected sleeve 121 and the screw pipe 122 can be quickly and stably connected together by friction welding. Such an anchor rod device can quickly adapt to different anchoring environments and can better meet actual anchoring needs.

[0032] The fiberglass rod 2 is a glass fiber steel bar or a glass fiber bar, which is much lighter than steel bars of the same specifications (diameter and length specifications), and has a higher tensile strength than steel bars of the same specifications (diameter and length specifications), so it can meet the design requirements very well.

[0033] In the actual manufacturing process, a lightweight and high-strength metal rod can also be used to replace the fiberglass rod 2, which can also meet the design requirements.

[0034] The sleeve 121 is pressed onto the fiberglass rod 2 or grout is injected into the sleeve 121 to secure the fiberglass rod 2. This ensures that the sleeve 121 secures the fiberglass rod 2 stably and reliably, thereby improving the reliability of the anchor device. Furthermore, the use of press-fitting can improve the efficiency of the installation, thereby facilitating assembly.

[0035] When actually buckling and pressing, first put the sleeve tube 121 on the glass fiber rod 2, and then send them together into the buckling machine for buckling, so that the buckling and assembly requirements can be met.

[0036] When the grouting connection is actually performed, at least one grouting hole (not shown in the figure) is opened on the outer wall of the sleeve 121 and penetrates into the interior thereof, and cement slurry or cement mortar is poured into the grouting hole using grouting equipment, so that the cement slurry or cement mortar passes through the grouting hole and enters between the inner wall of the sleeve 121 and the fiberglass rod 2, thereby achieving the grouting fixation requirement.

[0037] During the crimping connection, the sleeve tube 121 can be made of a tube with a lower hardness than the screw tube 122. This facilitates the crimping connection while ensuring the screw connection strength of the screw tube 122. This allows the two ends of the connecting rod body 12 to be selected according to their own connection requirements, eliminating the need to select high-strength materials. This helps control the manufacturing difficulty and cost of the anchor device, and also ensures that the anchor device has a very high reliability.

[0038] like Figure 3 As shown, the length of the sleeve 121 is greater than the length of the screw sleeve 122. This allows the sleeve 121 to have sufficient sleeve volume, thereby improving the stability and reliability of the assembly, and further helping to further improve the reliability of the anchor device.

[0039] like Figure 3 As shown, the length of the sleeve 121 is more than five times greater than the length of the screw sleeve 122. This can help to make the assembly more reliable, thereby helping to further improve the reliability and applicability of the anchor device.

[0040] like Figure 1 and Figure 2 As shown, the anchor device also includes a pad 3, a nut 4, a screw 5, and a connecting tube 6. One end of the connecting tube 6 is sleeved on the outer end of the fiberglass rod 2 arranged at the head end, and the screw 5 is screwed onto the other end of the connecting tube 6. The pad 3 is sleeved on the screw 5, and the nut 4 is screwed onto the screw 5. The nut 4 and the connecting tube 6 jointly clamp the pad 3 on the screw 5. This can help form a stable and reliable locking end, thereby helping to improve the reliability and stability of the locking of the anchor device.

[0041] like Figure 4 and Figure 5 As shown, a thin nut 7 is screwed onto the screw 5 between the backing plate 3 and the connecting tube 6, and the backing plate 3 is clamped and positioned on the screw 5 by the nut 4 and the thin nut 7. This can help to enhance the locking strength of the screw 5, thereby further improving the stability and reliability of the locking.

[0042] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the connecting tube body 6 includes a sleeve tube 61 and a threaded tube 62. One end of the sleeve tube 61 and one end of the threaded tube 62 are friction-welded together. The sleeve tube 61 is sleeved onto the outer end of the fiberglass rod 2 arranged at the head end, and the threaded tube 62 is screwed onto the screw rod 5. This allows the sleeve tube 61 and the threaded tube 62 to be made of suitable materials, respectively, to facilitate the sleeve tube 61 and the threaded tube 62 to achieve a strong sleeve connection and a strong screw connection. This facilitates the connection between the sleeve tube 61 and the fiberglass rod 2, and the connection between the threaded tube 62 and the screw rod 5 to be perfectly handled. In addition, the threaded tube 62 and the sleeve tube 61 are friction-welded together, which not only ensures high assembly efficiency but also ensures a very stable and reliable connection between the threaded tube 62 and the sleeve tube 61. This structure ensures that the connecting tube body 6 has a very stable and reliable connection strength, which not only helps to reduce the manufacturing difficulty and manufacturing cost of the anchor device, but also ensures that the anchor device has a very high reliability.

[0043] In the actual manufacturing process, the structure of the connecting tube body 6 and the connecting rod body 12 can adopt the same structure, which can help improve the convenience of batch manufacturing, and the connecting tube body 6 and the connecting rod body 12 can bring the same effect.

[0044] In the actual manufacturing process, the sleeve tube 121, the screw tube 122, the sleeve tube 61 and the threaded tube 62 are all made of steel pipes, which not only meets the requirements of friction welding, but also ensures that the structural strength is very high, thereby being able to meet the needs of actual use very well.

[0045] The sleeve 61 is pressed onto the fiberglass rod 2 or grouting is performed inside the sleeve 61 to secure the fiberglass rod 2. This ensures that the sleeve 61 secures the fiberglass rod 2 stably and reliably, thereby improving the reliability of the anchor device. Furthermore, the use of press-fitting can improve the efficiency of the sleeve, thereby facilitating assembly.

[0046] When actually buckling and pressing, the sleeve tube 61 is first sleeved on the fiberglass rod 2, and then they are sent together into the buckling machine for buckling and pressing, which can meet the buckling and assembly requirements.

[0047] When the grouting connection is actually performed, at least one grouting hole (not shown in the figure) is opened on the outer wall of the sleeve tube 61 and penetrates into the interior thereof, and cement slurry or cement mortar is poured into the grouting hole using grouting equipment, so that the cement slurry or cement mortar passes through the grouting hole and enters between the inner wall of the sleeve tube 61 and the fiberglass rod 2, thereby achieving the grouting fixation requirement.

[0048] During the crimping connection, the sleeve tube 61 can be made of a tube with a lower hardness than the threaded tube 62. This facilitates the crimping connection while ensuring the threaded strength of the threaded tube 62. This allows the two ends of the connecting rod body 12 to be selected according to their respective connection requirements, eliminating the need to select high-strength materials. This helps control the manufacturing difficulty and cost of the anchor device, and also ensures that the anchor device has a very high reliability.

[0049] like Figure 5 As shown, the length of the sleeve tube 61 is greater than the length of the threaded tube 62. This enables the sleeve tube 61 to have sufficient sleeve volume, thereby being beneficial to improving the stability and reliability of the assembly, thereby contributing to further improving the reliability of the anchor device.

[0050] like Figure 5 As shown, the length of the sleeve tube 61 is more than five times greater than the length of the threaded tube 62. This can help to make the assembly more reliable, thereby helping to further improve the reliability and applicability of the anchor device.
