Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a simple reinforcing bar embedding glue injection device. Background Art

[0002] The existing technology uses steel bars glued with rebar embedding glue to plug into the rebar embedding hole, and the steps are as follows:

[0003] S1: Preparation

[0004] According to the plan on the drawing, drill holes at designated locations, and the hole depth is usually 10d to 15d (d is the diameter of the steel bar).

[0005] Clean the holes and make sure there is no dust or debris in them.

[0006] S2: Glue injection process

[0007] Select the appropriate anchor glue and inject the glue according to the type of anchor glue (injection type or barreled).

[0008] Injection type rebar glue: Use glue injection tool to inject the glue into the hole to 2 / 3 of the hole depth.

[0009] Barreled anchor glue: Mix materials A and B in proportion, stir evenly and inject into the holes.

[0010] S3: Insert reinforcement

[0011] Stick the steel bars to the anchor glue that has been injected into the hole to ensure full contact between the steel bars and the glue.

[0012] Slowly insert the steel bar into the hole clockwise until it reaches the designed depth.

[0013] By adopting the above steps, the amount of glue injection cannot be controlled, and different rebar embedding holes cannot be satisfied, which is inconvenient for turnover and high in cost.

[0015] In view of this, the present invention provides a simple rebar embedding glue injection device, by which the rebar embedding glue can be directly injected into the bottom of the hole. When the steel bars are implanted, the rebar embedding glue is squeezed out of the rebar embedding hole from the bottom of the hole, thereby ensuring the density of the rebar embedding glue. By replacing different glue injection tubes and pistons to meet the needs of different rebar embedding holes, reuse is achieved.

[0016] The present invention provides a simple rebar-embedded glue injection device that adopts the following technical solution:

[0018] Optionally, the glue injection tube is marked with scales.

[0019] Optionally, circular holes having the same diameter as the transmission rod are provided at the center positions on both sides of the fixed sleeve.

[0020] Optionally, the piston is detachably connected to the transmission rod.

[0021] Optionally, the locking member is a bolt, and a bolt hole for the bolt to pass through is formed on the outer sleeve, and the bolt is pressed against the outer wall of the glue injection tube through the bolt hole.

[0022] Optionally, an airbag ring is provided on the inner wall of the outer sleeve, and the airbag ring can be manipulated to expand by inflation or contract by deflating. When the airbag ring is inflated, the glue injection tube can be pressed tightly.

[0029] The following is combined with Figure 1-2 The present invention is described in further detail.

[0030] The embodiment of the invention discloses a simple reinforcing bar embedding glue injection device.

[0031] Reference Figure 1 , Figure 2 A simple rebar glue injection device includes a fixed sleeve 6, a glue injection tube 1, a transmission rod 7 and a piston 2. The fixed sleeve 6 is provided with a round hole, and the transmission rod 7 is slidably arranged in the round hole. An outer sleeve 3 is arranged outside the fixed sleeve 6, and a piston 2 is arranged at the end of the transmission rod 7. The piston 2 is connected to the transmission rod 7. The front end of the fixed sleeve 6 is provided with a conical surface, which is used to abut against the glue injection tube 1. The outer sleeve 3 is provided with a locking piece for fixing the glue injection tube 1 to the fixed sleeve 6. The piston 2 is slidably arranged in the glue injection tube 1. The rebar glue is filled into the bottom of the hole at one time, and the injected rebar glue can be measured to ensure that the rebar glue is full and dense.

[0032] The glue injection tube 1 is marked with a scale 9 to facilitate observation and control of the amount of glue injected and accurate glue injection.

[0033] Circular holes with the same diameter as the transmission rod 7 are provided at the center positions on both sides of the fixed sleeve 6, which ensure precise fit: the design of the circular hole with the same diameter as the transmission rod 7 ensures the precise fit between the transmission rod 7 and the fixed sleeve 6, reduces the gap, and improves the stability and accuracy of the transmission; simplifies installation: this design also simplifies the installation process, so that the transmission rod 7 can be easily and accurately inserted into the fixed sleeve 6, thereby improving work efficiency.

[0034] The piston 2 is detachably connected to the transmission rod 7. In the present embodiment, the piston 2 is threadably connected to the transmission rod 7. The piston 2 and the transmission rod 7 are detachably connected. By replacing pistons 2 of different sizes, different sizes of injection tubes 1 can be adapted to improve applicability and adapt to different sizes of rebar holes.

[0035] The locking piece is a bolt 5, and a bolt hole 4 for the bolt 5 to pass through is opened on the outer sleeve 3. The bolt 5 is pressed against the outer wall of the injection tube 1 through the bolt hole 4. The injection tubes 1 of different sizes are fixed by the bolt 5. By replacing the injection tubes 1 of different sizes, it can adapt to the rebar holes of different sizes, thereby improving the applicability.

[0036] An airbag ring 10 is provided on the inner wall of the outer sleeve 3. The airbag ring 10 can be manipulated to inflate or contract by vacuum. When the airbag ring 10 is inflated, the injection tube 1 can be pressed tightly. A closable inflation port is provided on the outer sleeve 3. The airbag ring 10 is inflated by inflating the inflation port, and the injection tube 1 is pressed tightly between the airbag ring 10 and the fixed sleeve 6 to achieve the fixation of the injection tube 1 and the fixed sleeve 6. Convenient fixation, the airbag ring 10 is manipulated through the inflation port to achieve rapid fixation and release. Strong adaptability: The expansion degree of the airbag ring 10 is adjustable to adapt to injection tubes 1 of different diameters. Protect the injection tube 1: The material of the airbag ring 10 is soft to avoid damage to the injection tube 1; High convenience: The expansion and contraction of the airbag ring 10 can be quickly achieved through the inflation port, and the operation is simple and quick, while the bolt 5 fixation requires the rotation of the bolt 5, and the operation is relatively cumbersome.

[0037] The transmission rod 7 is provided with a gripping rod 8 , and the gripping rod 8 can be manipulated to drive the transmission rod 7 to slide along the axial direction of the fixing sleeve 6 .

[0038] The piston 2 is a stainless steel piston 2. The stainless steel piston 2 rod has excellent corrosion resistance, enhanced wear resistance, and optimized sealing performance. The stainless steel piston 2 rod has good rigidity and high strength, which can effectively reduce the friction damage to the sealing ring or sealing member when the piston 2 moves.

[0039] Circular holes with the same diameter as the transmission rod 7 are provided at the center positions on both sides of the fixed sleeve 6. The transmission rod 7 passes through the circular holes on both sides to ensure that the moving direction of the transmission rod 7 remains unchanged relative to the fixed sleeve 6. An outer sleeve 3 is provided outside the fixed sleeve 6. The outer sleeve 3 is provided with bolt holes 4 according to the fixed position of the injection tube 1 at the end of the fixed sleeve 6. A piston 2 with a corresponding aperture is provided at the end of the transmission rod 7 and is connected to the transmission rod 7 through a thread. The injection tube 1 is inserted into the outer sleeve 3 and is tightly connected to the corresponding fixed position of the fixed sleeve 6. The injection tube 1 is firmly fixed to the fixed sleeve 6 by bolts 5, or fixed by an airbag ring 10; when injecting glue, the amount of the reinforcement glue is calculated by the difference in volume between the reinforcement hole and the steel bar, the piston 2 is dragged to the scale 9 consistent with the amount of the reinforcement glue, and then the reinforcement glue is filled in the injection tube 1, and then the injection tube 1 is inserted into the reinforcement hole to the bottom of the hole, and the reinforcement glue in the injection tube 1 is pushed into the bottom of the reinforcement hole, and then the steel bar is inserted to complete the reinforcement work.
