Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering anchor rod, particularly relates to an integrated carrier. BACKGROUND

[0002] In the anti-floating engineering field, the tension-compression composite anchor rod technology is gradually popularized and applied, and the technology needs to set a pressure that can convert the anchor rod tension to the pressure acting on the anchor rod grouting body at the middle position of the anchor rod reinforcement. For the steel strand, there is a special extrusion sleeve and a matching carrier plate; for the reinforcement, the traditional method can only use the way of helping strip welding, which leads to very complex construction process, extremely low construction efficiency, and it is difficult to fully guarantee the construction quality. With the gradual popularization and application of the reinforcement anti-floating anchor rod, especially the application of the finished rolled threaded reinforcement in the anti-floating anchor rod field, although the traditional full-bonding anchor rod can be directly installed in the steel reinforcement in the drilling hole, because the steel reinforcement and the grouting body produce interface shear, the grouting body and the rock-soil body interface produce shear, when the load is large, the grouting body is prone to cracking due to tension, which leads to durability problems such as steel corrosion and reduced bearing capacity. The tension-compression composite anchor rod not only has high bearing capacity, but also has good corrosion resistance, and is gradually applied. The tension-compression composite anchor rod relies on the bearing pressure anchor rod section and the tension anchoring to bear load, therefore, the carrier of the bearing pressure anchoring section is the key component to ensure the bearing pressure anchoring section to play a bearing role, and the insufficient compression bearing capacity of the grouting body of the bearing pressure anchoring section at the carrier will lead to the destruction of the bearing pressure anchoring section first, and then the destruction of the tension anchoring, which leads to the failure of the two to bear load cooperatively. At present, the carrier of the tension-compression composite anti-floating anchor rod technology for the finished rolled threaded reinforcement is not standardized. Based on this, in order to fully guarantee the compression bearing capacity of the grouting body of the bearing pressure anchoring section of the tension-compression composite anti-floating anchor rod, the research and creation of the utility model are carried out.

[0083] The embodiment provides an integrated carrier 220, as shown in the figure, the horizontal section of the carrier cap 222 in the embodiment is circular, and the carrier plate 221 is integrally formed with the carrier cap 222. In specific implementation, the forging and casting process can be used for integrated machining and forming, and after the carrier cap 222 is installed on the steel bar, the connecting force with the steel bar is not less than the ultimate uplift bearing capacity of the carrier applied to the anchor rod. Preferably, in the embodiment, the pipe penetrating hole 224 is a circular hole arranged near the edge of the carrier plate 221, and the pipe penetrating hole 224 can also be a semicircular hole arranged at the edge of the carrier plate 221. Figures 1 to 3

[0084] In addition, in order to enhance the uplift bearing capacity of the carrier, the existing carrier is provided with a stiffening rib at the bottom of the carrier plate 221, but the prior art is to weld the external stiffening rib to the carrier plate 221, which also causes the problem of complex production process of the carrier.

[0085] To solve this technical problem, the utility model is provided with a reinforcing cone 226 at the bottom of the carrier plate 221, as shown in the figure. Figures 4 to 5 ​As shown, the vertical height of the reinforcing cone 226 linearly increases from the edge of the bearing plate 221 to the bearing cap 222 with a preset slope, so that the bearing plate 221 has a slope at the bottom, and the reinforcing cone 226 is integrally formed with the bearing plate 221 and the bearing cap 222. By setting the reinforcing cone 226, the uplift bearing capacity of the bearing body is improved, and at the same time, the reinforcing cone 226 is arranged at the bottom of the bearing plate 221 and integrally formed with the bearing plate 221 and the circular bearing cap 222. Specifically, the forging and casting process can be used for integrated machining.

[0086] Preferably, as Figure 6 As shown, the inner wall of the third reinforcing hole 223 of the bearing plate 221 and the bearing cap 222 is provided with a continuous internal thread 225. Specifically, the outer surface of the finishing rolled threaded steel bar installed on the bearing body is provided with an external thread, and the inside of the third reinforcing hole 223 is provided with a matching internal thread 225. The external thread of the outer surface of the threaded steel bar is threadedly connected with the internal thread 225 inside the third reinforcing hole 223, which ensures the stability of the bearing body installation.

[0089] In specific implementation, the horizontal section of the bearing plate 221 is circular, the bearing body is fixed to the threaded steel bar through the third reinforcing hole 223, the bearing plate 221 is arranged upward towards the borehole opening, and the area of the circular bearing plate 221 is large enough, so that the pipe penetrating hole 224 can be arranged on the surface of the bearing plate 221, thereby facilitating the installation of the grouting pipe.

[0090] In an embodiment, the number of pipe penetrating holes 224 is two. Specifically, generally only two grouting pipes are installed for grouting in the actual construction process, and the number of grouting pipes can also be set according to the number of grouting pipes. Alternatively, the pipe penetrating holes 224 can be symmetrically arranged around the center of the bearing plate 221, or can not be symmetrically arranged.

[0091] In an embodiment, as Figure 8 and Figure 10As shown, the horizontal section of the bearing cap 222 is hexagonal, and the bearing plate 221 is welded to the bearing cap 222. Specifically, the bearing cap 222 is a hexagonal nut, which is welded to the circular bearing plate 221 to form an integrated one-piece bearing body 220. At this time, the inner thread 225 of the third through-hole 223 of the bearing cap 222 is provided with an outer thread matched with the threaded steel bar, and the hexagonal nut is consistent with the strength of the threaded steel bar. After the bearing cap 222 is installed on the steel bar, the connection force with the steel bar is not less than the ultimate uplift bearing capacity of the bearing body applied to the anchor rod.

[0092] Preferably, as Figures 7 to 10 shown, the pipe hole 224 is a circular hole arranged near the edge of the bearing plate 221.

[0093] Example three

[0094] In this embodiment, the pipe hole 224 is a semicircular hole arranged at the edge of the bearing plate 221. Specifically, as Figures 11 to 15 shown, the pipe hole 224 is a semicircular notch arranged at the edge of the bearing plate 221. When the construction period is very tight, the grouting pipe can be directly clamped on the semicircular notch for quick binding and fixing, and the horizontal section of the bearing cap 222 is hexagonal.

[0095] The remaining structure is the same as that of example one, and will not be described here.

[0096] Example four

[0097] The utility model provides a pressure type prestressed anti -floating anchor rod, as Figures 16 to 21 shown, including threaded steel bar 110 and the anchoring device 200, pre -tightening device 210, water stop ring 240, assembly type support 260, one -piece bearing body 220 and end cap 250 connected from top to bottom along threaded steel bar 110, anchoring device 200, pre -tightening device 210, assembly type support 260, one -piece bearing body 220 and end cap 250 can be detachably connected on threaded steel bar 110, and water stop ring 240 is fixed in drill hole 104.

[0098] The steel pipe 112 is arranged between the pre-tightening device 210 and the assembly type support 260, the isolation sleeve 111 is arranged between the pre-tightening device 210 and the one-piece bearing body 220, and the one-piece bearing body 220 to the cushion layer 103 forms the pressure bearing anchoring section 108. Specifically, the two ends of the isolation sleeve 111 are sealed.

[0099] In an embodiment, as Figure 22As shown, the anchoring device 200 comprises a first nut 201 and a first steel backing plate 202, the first steel backing plate 202 is connected perpendicularly with the first nut 201, the first steel backing plate 202 and the first nut 201 are provided with a first rebar passing hole 203 in communication, the inner wall of the first rebar passing hole 203 forms an internal thread 225, which is adapted to be screw-connected with the external thread of the threaded rebar 110.

[0100] In an embodiment, the pre-tightening device 210 comprises a second nut 211 and a second steel backing plate 212, the second steel backing plate 212 is connected perpendicularly with the second nut 211, the second steel backing plate 212 and the second nut 211 are provided with a second rebar passing hole 213 in communication, the inner wall of the second rebar passing hole 213 forms an internal thread 225, which is adapted to be screw-connected with the external thread of the threaded rebar 110.

[0101] In an embodiment, the carrier is the integrated carrier 220 as described in any one of the embodiments one, two and three, which has the same structure and will not be described here again.

[0102] In an embodiment, the outer side of the integrated carrier 220 is sleeved with a spiral rebar 113, the diameter of the spiral rebar 113 is greater than the longest length of the carrier plate 221 of the integrated carrier 220, and the spiral rebar 113 is used for transversely or radially restraining the grouting body 105. Specifically, the outer side of the integrated carrier 220 is sleeved with the spiral rebar 113, and the diameter of the spiral rebar 113 is greater than the longest length of the carrier plate 221 of the integrated carrier 220. Preferably, the integrated carrier 220 in the utility model is a circular integrated carrier 220, and the diameter of the spiral rebar 113 is greater than the diameter of the integrated carrier 220. When the cross section of the carrier plate 221 is an ellipse, the diameter of the spiral rebar 113 is greater than the length of the major axis of the integrated carrier 220.

[0103] Specifically, since the top surface of the carrier plate 221 of the integrated carrier 220 is a slope surface or a spherical surface symmetrical along the major axis, when the grouting body 105 is extruded, the splitting effect on the grouting body 105 is generated. The outer side of the integrated carrier 220 is sleeved with the spiral rebar 113, which has a strong transverse or radial restraining effect on the grouting body 105, significantly improves the compressive bearing capacity of the grouting body 105, thereby fully guarantees the cooperative bearing of the pressure-anchoring section 108 and the tension-anchoring section 109, and greatly improves the anti-pulling bearing capacity of the tension-compression type anti-floating anchor rod.

[0104] In an embodiment, the water stop ring 240 comprises an upper ring tube 241, a lower ring tube 242 and a ring plate 243, the upper ring tube 241 is above the ring plate 243, the lower ring tube 242 is below the ring plate 243, the ring plate 243 is provided with a ring plate hole 243a, the upper ring tube 241 and the lower ring tube 242 are hollow to form an upper ring hole 241a and a lower ring hole 242a, and the normal axis of the upper ring hole 241a, the ring plate hole 243a and the lower ring hole 242a coincide.

[0105] Specifically, when the normal axes coincide, the plane of the ring plate 243 is vertically arranged with the upper ring tube 241 and the lower ring tube 242. The water stop ring 240 is embedded between the bottom plate 100 and the drill hole 104, and a cushion layer 103 is further arranged between the bottom plate 100 and the drill hole 104, the ring plate 243 abuts against the cushion layer 103, and the anchor bar reinforcement 110 is placed in the drill hole 104 after passing through the upper ring hole 241a, the ring plate hole 243a and the lower ring hole 242a. The sidewalls of the upper ring tube 241 and the lower ring tube 242 can effectively prevent the underground water from permeating between the bottom plate 100 and the cushion layer 103, and between the cushion layer 103 and the soil layer of the drill hole 104, thereby avoiding the corrosion of the reinforcement.

[0106] Preferably, as shown in Figures 23 to 25 , the diameter of the upper ring hole 241a is the same as or smaller than the diameter of the ring plate hole 243a and the lower ring hole 242a.

[0107] In an embodiment, the water stop ring 240 is further provided with a sleeve ring tube 244, which is installed outside the upper ring tube 241, as shown in Figure 26 , the upper ring tube 241 is symmetrically provided with a hanging bar setting groove 245, as shown in Figure 27 , the sleeve ring tube 244 is symmetrically provided with a hanging bar cover hole 246, which is oppositely arranged with the hanging bar setting groove 245.

[0108] In actual implementation, the diameters of the anchor bar reinforcements 110 required to be fixed are quite different, and the diameters of the anchor bar reinforcements 110 required in different geological environments are also different.

Preferably, the shape of the hanging bar setting groove 245 is rectangular, which can be more conducive to the placement of the anchor bar reinforcement 110.

[0109] In an embodiment, as shown in Figure 28 , Figure 29As shown, the sleeve pipe 244 is sleeved outside the upper ring pipe 241 and detachably connected with the water stop ring 240. The sleeve pipe 244 includes transverse plates 244a and longitudinal plates 244b perpendicular to each other. The lifting bar cover holes 246 are arranged at the bottom of the longitudinal plates 244b. The hole openings of the lifting bar cover holes 246 can completely match the cross sections of the horizontal lifting bars 247. The distance between the lifting bar cover holes 246 can be determined according to the diameter of the anchor rod steel bars 110. The lifting bar arrangement grooves 245 of the upper ring pipe 241 are matched with the lifting bar cover holes 246 of the sleeve pipe 244. The lifting bar arrangement grooves 245 can match the installation requirements of different types of steel bars. Meanwhile, the mold of the upper ring pipe 241 does not need to be additionally provided. Only the sleeve pipe 244 needs to be produced according to different requirements, which greatly reduces the cost.

[0110] Preferably, as Figure 27 shown, the shape of the lifting bar cover hole 246 is a groove or a semicircle. Specifically, the cross section of the anchor rod steel bar 110 is generally circular. The lifting bar cover hole 246 is provided in the shape of a groove or a semicircle, which can better adapt to the anchor rod steel bar 110.

[0111] In an embodiment, as Figures 30 to 33 shown, the end cap 250 includes a ball head 253, a screw groove 251, flexible blades 254, and a stiffening rib 252. The ball head 253 is a hollow hemisphere. Two flexible blades 254 are connected to the upper part of the ball head 253. The horizontal cross-sectional diameter of the flexible blades 254 gradually increases upward. The cross section of the ball head 253 and the flexible blades 254 connected together is in the shape of “U”. The screw groove 251 is arranged in the inner center of the ball head 253. The stiffening rib 252 is arranged between the ball head 253 and the screw groove 251. The stiffening rib 252 is symmetrically arranged at a preset angle around the screw groove 251.

[0112] In an embodiment, as Figures 34 to 38 shown, the assembled support 260 includes a first support piece 260a, a second support piece 260b, and a connecting piece 267. The shapes of the first support piece 260a and the second support piece 260b are symmetrical.
