Description

Technical Field

[0001] The present application relates to the technical field of anchor rods, and more specifically, to an anchor rod device with adjustable length. Background Art

[0002] As a tension member deep in the ground, the anchor rod is connected to the engineering structure at one end and deep in the ground at the other end. The whole anchor rod is divided into a free section and an anchoring section. The free section refers to the area where the tension at the anchor rod head is transmitted to the anchor body, and its function is to apply prestress to the anchor rod; the anchoring section refers to the area where the cement slurry bonds the prestressed tendons to the soil layer, and its function is to increase the bonding friction between the anchor body and the soil layer, increase the bearing pressure of the anchor body, and transmit the tension of the free section to the deep soil.

[0003] A document with prior art disclosure (announcement) number CN215211017U provides an anchor rod device with adjustable length for municipal engineering. In the related technology of the device, the threaded rotating rod and the extension rod are set to better lengthen the threaded rotating rod, so that it is convenient to drive the threaded rotating rod into the ground, and then the cement mortar can be better poured in through the first grouting groove and the second grouting groove, and then the cement mortar can be better flowed out by setting a small hole on the rotating head at the lower end of the threaded rotating rod, so as to facilitate the fixing of the anchor rod by the poured cement mortar, thereby making the anchor rod more stable.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the anchor rod structure is composed of an extension rod connected to a threaded rotating rod, and its main body structure still does not have a telescopic adjustment function.

[0005] In view of this, we propose an anchor device with adjustable length. Utility Model Content

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 1-3 An adjustable length anchor rod device in an embodiment of the present application includes:

[0031] A rod barrel 1 and a rod sleeve 2 constituting an anchor rod;

[0032] The rotating head 3 is threadedly connected to one end of the rod barrel 1;

[0033] The screw tube 4 is tightly welded to one end of the rod sleeve 2;

[0034] The threaded plug 5 with a hemispherical structure at one end is threadedly connected in two screw holes 21 outside the rod sleeve 2 and is plugged and adapted to a plurality of jacks 11 provided at equal intervals outside the rod tube 1 .

[0035] The adjustable length anchor rod device forms a telescopic anchor rod structure by utilizing the sliding cooperation between the rod tube 1 and the rod sleeve 2, so that the anchor rod structure can be telescopically adjusted in length, and under the connection of the threaded plug 5, the position of the telescopically adjusted anchor rod structure is limited to achieve the locking use of the anchor rod structure.

[0036] Reference Figure 1 and Figure 2 In the anchor rod device with adjustable length recorded in the embodiment of the present application, a marking groove 12 is opened on the outside of the rod tube 1 relative to the position between the two insertion holes 11, and the marking groove 12 is painted with fluorescent paint.

[0037] The length-adjustable anchor device uses a marking groove 12 coated with fluorescent paint to mark and cooperate with the bottom of the extended rod sleeve 2, so as to achieve alignment of the screw hole 21 between the rod sleeve 2 and the rod barrel 1 and the hole 11, facilitate the precise threaded docking installation of the threaded plug 5, and improve the rapid connection operation of the anchor structure composed of the rod barrel 1 and the rod sleeve 2.

[0038] Reference Figure 1 and Figure 2 In the adjustable length anchor device recorded in the embodiment of the present application, a material guide cylinder 22 is tightly welded inside the rod sleeve 2, the material guide cylinder 22 is slidably matched with the rod barrel 1, and the material guide cylinder 22 is tightly fitted with a sealing ring 13 embedded inside the rod barrel 1 to limit the position.

[0039] The anchor rod device with adjustable length utilizes the sealing cooperation between the material guide tube 22 and the rod tube 1 through the sealing ring 13, so as to facilitate the stable discharge of the slurry poured in the later stage.

[0040] Reference Figure 1 and Figure 2 In the adjustable length anchor device described in the embodiment of the present application, the threaded hole diameters of the rotating head 3 and the screw tube 4 are consistent, and a plurality of slurry discharge holes are opened on the inclined surface of the rotating head 3, and an elastic hinge 31 is hingedly installed on the outside of the slurry discharge holes.

[0041] The anchor rod device with adjustable length utilizes the sealing cooperation between the material guide tube 22 and the rod tube 1 through the sealing ring 13, so as to facilitate the stable discharge of the slurry poured in the later stage.

[0042] Working principle: when the length of the anchor structure needs to be adjusted, the operator screws the threaded plug 5 externally with a wrench. After the threaded plug 5 is removed, the rod barrel 1 and the rod sleeve 2 are stretched to adjust the length, and the bottom end of the rod sleeve 2 is fitted with the marking groove 12, so that the insertion hole 11 and the screw hole 21 can be aligned. Because the position of the insertion hole 11 is in the standard position with the external thread grooves of the rod barrel 1 and the rod sleeve 2, and then, after the rod barrel 1 and the rod sleeve 2 are connected and limited by the threaded plug 5, the thread grooves between the rod barrel 1 and the rod sleeve 2 are still in an aligned state, which does not affect the later thread installation of the nut outside the anchor structure.
