Description

Technical Field

[0002] In the traditional rebar embedding and glue injection process, the construction process is cumbersome and inefficient. First, workers need to use a drilling machine to accurately drill holes at designated locations, and then clean the holes to ensure that the hole walls are clean and free of impurities. Next, workers need to dig out the rebar embedding glue and curing agent separately and mix them manually on a wooden board. This step is not only time-consuming and labor-intensive, but also manual mixing is subject to human interference. The mixed mixture is then applied to the steel bars to be implanted, and then the steel bars are inserted into the rebar embedding holes. However, this manual application method often results in part of the glue being retained outside the hole during the insertion of the steel bars, resulting in uneven distribution of glue in the rebar embedding hole, and even insufficient glue, which seriously affects the rebar embedding effect and structural strength.

[0003] Therefore, there is an urgent need for a double-cavity rebar embedding glue injection device with a simple structure and reasonable design, which can be inserted into the rebar embedding hole for injection so as to evenly and sufficiently fill the entire rebar embedding hole, thereby improving the rebar embedding effect and structural strength, and reducing manual operation steps, and realizing the simultaneous injection of rebar embedding glue and curing agent, which can not only greatly shorten the construction period, but also reduce labor intensity and improve overall construction efficiency.

[0053] The sealing cover 10 is arranged at the end of the double-chamber glue injection cylinder 2 close to the guiding seat 8.

[0054] In this embodiment, the upper clamping plate member includes a clamping ring 6 arranged at the end of the bearing plate 5 close to the injection syringe 9 and an opening and closing plate 7 arranged at the top of the clamping ring 6 and connected by a hinge.

Both ends of the lower groove 2-3 and the upper groove 2-4 have gaps with both ends of the double-chamber glue injection cylinder 2.

[0056] A lower protruding strip 5-1 integrally formed and inserted into the lower groove 2-3 is arranged at the top of the bearing plate 5, and an upper protruding strip 7-1 integrally formed and inserted into the upper groove 2-4 is arranged at the bottom of the opening and closing plate 7.

[0057] In this embodiment, a first limiting hole 1-9 is arranged on the hand rocker 1-2, and a second limiting hole 1-A is arranged on the base plate 1-3. The first limiting hole 1-9 and the second limiting hole 1-A are matched for the insertion of a pin shaft.

[0058] In this embodiment, the double-chamber glue injection cylinder 2 is provided with two semi-cylindrical bodies 2-1 spliced together. One semi-cylindrical body 2-1 contains planting bar glue, and the other semi-cylindrical body 2-1 contains curing agent. Then, the piston 4-4 is pushed by the piston rod 4-3 so that the planting bar glue and the curing agent are synchronously injected into the planting bar hole through two outlets of the injection syringe 9, avoiding the need to mix and apply the planting bar glue and the curing agent in advance, reducing the manual operation steps, and realizing the rapid injection of the planting bar glue and the curing agent, thus improving the overall construction efficiency.

[0059] In this embodiment, during actual use, glue injection ports are provided on the side walls of the two semi-cylindrical bodies 2-1, and sealing plugs are detachably arranged on the glue injection ports.

[0060] In this embodiment, during actual use, the double-chamber glue injection cylinder 2 is detachably installed on the clamping body, improving the operation convenience.

[0061] In this embodiment, during actual use, by rotating the hand rocker 1-2 in the manual pushing mechanism 1, the piston 4-4 is driven to move inside the double-chamber glue injection cylinder 2, so as to push the planting bar glue and the curing agent in the double-chamber glue injection cylinder 2 to be extruded respectively and then mixed in the planting bar hole. In this way, through the uniform extrusion of the planting bar glue and the curing agent, it is ensured that the planting bar glue and the curing agent uniformly and sufficiently fill the entire planting bar hole, thereby improving the planting bar effect and the structural strength.

[0062] In this embodiment, a bearing plate and an upper clamping plate member are provided, so that the double-chamber glue injection cylinder 2 is detachably clamped between the bearing plate 5 and the upper clamping plate member, which is not only convenient for installation but also easy to disassemble; secondly, the stability of the double-chamber glue injection cylinder 2 is improved through clamping, effectively adapting to the rotation adjustment of the device.

[0063] In this embodiment, during actual use, the injection syringe 9 includes two semi-cylindrical long tubes spliced and integrally formed, and two outlets are provided at the head ends of the two semi-cylindrical long tubes;

[0064] A partition is provided inside the tapered joint 11, which also divides the inside of the tapered joint 11 into two cavities. In this way, after the tapered joint 11 is connected, it is ensured that the cavities of the two semi-cylindrical long tubes of the injection syringe 9, the two cavities of the tapered joint 11, and the two semi-cavities of the double-chamber glue injection cylinder 2 are sequentially communicated. Thus, when the planting bar glue and the curing agent pass through the double-chamber glue injection cylinder 2, the tapered joint 11, and the injection syringe 9 in sequence, they do not mix, and are only synchronously extruded and mixed at the outlet end of the injection syringe 9, effectively avoiding internal mixing and solidification from affecting the glue injection.

[0065] In this embodiment, it should be noted that the injection syringe 9 is detachably arranged at the end of the double-chamber glue injection cylinder 2 through the tapered joint 11, so as to facilitate the replacement of the injection syringe 9 according to the use requirements.

[0066] In this embodiment, lower grooves 2-3 are provided, and there are gaps between the two ends of the lower grooves 2-3 and the two ends of the double-chamber glue injection cylinder 2, so that the two ends of the double-chamber glue injection cylinder 2 are respectively regular circles, facilitating the threaded connection of the large-diameter section of the tapered joint 11 and the threaded connection of the sealing cover 10.

[0067] In this embodiment, the opening and closing plate 7 and the hinge are provided to remove the bolts to release the limit of the opening and closing plate 7, so as to open the opening and closing plate 7 along the hinge to facilitate the disassembly and assembly of the double-chamber glue injection cylinder 2; or operate the opening and closing plate 7 to close along the hinge and install bolts to press and buckle the opening and closing plate 7 on the step portion 8-5 to achieve the relative locking of the opening and closing plate 7, and further achieve the clamping of the double-chamber glue injection cylinder 2.

[0068] In this embodiment, the lower convex strip 5-1 and the upper convex strip 7-1 are provided so that the lower convex strip 5-1 at the top of the bearing plate 5 is inserted into the lower groove 2-3, and the upper convex strip 7-1 at the bottom of the opening and closing plate 7 is inserted into the upper groove 2-4 to achieve the clamping limit of the top and bottom of the double-chamber glue injection cylinder 2.

[0069] The snap ring 6 is provided for the end of the double-chamber glue injection cylinder 2 to penetrate through to achieve the axial limit of the double-chamber glue injection cylinder 2. And under the combined action of the snap ring 6, the lower convex strip 5-1 and the upper convex strip 7-1, it further assists in axial limit and radial limit, so as to effectively meet the glue injection requirements.

[0070] In this embodiment, during specific implementation, a rack portion that meshes with the gear 1-5 is provided at the bottom of the push plate 3 and is arranged along its length direction.

[0071] In this embodiment, during specific implementation, the bent portion 3-1 is provided to facilitate manual gripping by a person to assist in the operation.

[0072] In this embodiment, during specific implementation, two guiding seats 8 respectively cooperate with two piston rods 4-3 for guiding, and the guiding seats 8 can be integrally formed.

[0073] When the present utility model is specifically used, the planting glue and the curing agent are respectively poured into the two semi-cylindrical cavities of the double-chamber glue injection cylinder 2. The injection syringe 9 is inserted into the planting hole, the pin shaft is pulled out to release the locking of the hand crank 1-2, and the hand crank 1-2 is operated to rotate. The rotation of the hand crank 1-2 drives the gear 1-5 to rotate through the central shaft 1-6. The rotation of the gear 1-5 drives the push plate 3 to move through the meshing rack. The movement of the push plate 3 drives the two piston rods 4-3 to push the piston 4-4 to advance along the semi-cylindrical cavity through the transition rod 4-1 and the connecting rod 4-2. The piston 4-4 advancing along the semi-cylindrical cavity squeezes the planting glue and the curing agent to be extruded through the outlets of the double-chamber glue injection cylinder 2, the conical joint 11 and the injection syringe 9 in sequence separately. The extruded planting glue and curing agent are only mixed at the outlet end of the injection syringe 9, so as to uniformly and sufficiently fill the entire planting hole, thereby improving the planting effect and the structural strength.

[0074] Or release the locking of the hand crank 1-2 and operate the hand crank 1-2 to rotate in the reverse direction. The rotation of the hand crank 1-2 drives the gear 1-5 to rotate in the reverse direction through the central shaft 1-6. The reverse rotation of the gear 1-5 causes the push plate 3 to move in the reverse direction, thereby driving the piston 4-4 to withdraw along the semi-cylindrical cavity, facilitating the next glue filling and injection.

[0075] In summary, the structure of the utility model is simple and reasonably designed. It can extend into the rebar planting hole for injecting glue, so as to uniformly and sufficiently fill the whole rebar planting hole, thereby improving the rebar planting effect and structural strength, reducing the manual operation steps, and realizing the synchronous injection of the rebar planting glue and the curing agent. This can not only greatly shorten the construction period, but also reduce the labor intensity and improve the overall construction efficiency.

[0076] The above are only the preferred embodiments of the utility model, and do not impose any limitations on the utility model. Any simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical essence of the utility model still fall within the protection scope of the technical solution of the utility model.
