Description

Technical Field

[0001] The present invention relates to a technical field, and in particular to a drilling-free reinforcing bar planting method. Background Art

[0002] Nowadays, construction projects can be seen everywhere. In the construction process, from the post-embedded reinforcement of structural engineering construction to the post-embedded parts of decoration and renovation engineering, and even the wall connecting parts of curtain wall engineering, all construction links involve embedded reinforcement. The first step of the embedded reinforcement operation is drilling the embedded reinforcement holes. The quality of the embedded reinforcement holes is directly related to the pull-out resistance of the embedded reinforcement and even the structural safety. At the same time, the number of embedded reinforcements is usually large, and the efficiency of the hole drilling work will greatly affect the progress of the project.

[0003] Currently, rebar holes are drilled using mechanical drilling. However, since mechanical drilling requires operators to use handheld mechanical equipment, it requires a high operating space. Drilling operations are often performed in narrow areas or at high altitudes, making drilling operations difficult. This can lead to problems such as inaccurate drilling positions, tilted rebar holes, and insufficient hole depth. It can also prevent lightning protection rebar from connecting to the structural reinforcement, increasing resistance. Furthermore, handheld equipment can have large errors. When the number of rebars is large and dense, the construction quality and thickness of the rebar protective layer cannot be guaranteed, affecting the final rebar planting effect and making it difficult to meet the requirements for pullout, shear, and bending resistance. This is especially true for special rebar planting processes that require tilt angles, making mechanical drilling more difficult and quality assurance difficult. The use of handheld electric drills and other equipment during the rebar hole drilling process also poses certain safety risks and significantly affects work efficiency. These issues urgently need to be addressed. Summary of the Invention

[0030] The following is combined with Figure 1-7 The present invention is described in further detail.

[0031] The embodiment of the present invention discloses a drilling-free rebar planting method.

[0032] Reference Figure 1-7 A drilling-free rebar planting method comprises the following steps:

[0033] S1: Construction preparation: Prepare a flexible and easily removable part 1 with the same diameter as the steel bars used for planting reinforcement and a fixing part 2 for fixing the flexible and easily removable part 1;

[0034] S2: Pre-embedded construction: During the reinforcement binding stage or masonry construction stage, the flexible and easily removable component 1 is placed at the location where reinforcement is required and fixed with the fixing component 2;

[0035] S3: removing the formwork and cleaning the hole: after the concrete construction is completed and the formwork is removed, the flexible and easily removable part 1 is taken out at the rebar planting position to form the rebar planting hole, and the debris and sediment in the rebar planting hole are cleaned;

[0036] S4: Anchoring: Anchor glue and insert steel bars into the anchoring holes.

[0037] The fixing member 2 is a tie wire. First, the flexible and easily detachable member 1 is fixed by the steel bar, and then the steel bar is tied and fixed with the tie wire.

[0038] In this embodiment, the flexible, easily removable component 1 includes a support member 3, a first airbag 4, and a second airbag 5. The first airbag 4 is wrapped around the outside of the support member 3 and is designed to abut the sidewalls of the rebar hole. The second airbag 5 is located at the bottom of the support member 3 and is designed to abut the bottom of the rebar hole. The inner sidewall of the first airbag 4 and the outer sidewall of the second airbag 5 can abut. By controlling the airbag's inflation level, the required rebar holes of different sizes can be created, improving applicability.

[0039] The support member 3 is made of a hard material, and in this embodiment, aluminum alloy is used. The support member 3 is cylindrical, and the support member 3, the first airbag 4, and the second airbag 5 are coaxially arranged to effectively ensure inflation consistency and uniform expansion of the first airbag 4.

[0040] The support member 3 has a connecting hole 31 extending along the depth of the rebar hole. The first airbag 4 is provided with an air inlet 6 and an air outlet 7. The air outlet 7 is located lower than the first airbag 4, below the bottom of the support member 3 and disposed on the inner sidewall of the first airbag 4. The second airbag 5 is provided with a vent that communicates with the connecting hole 31 of the support member 3. The bottom of the second airbag 5 is open and communicates with the vent. Multiple first airbags 4 can be installed. In this embodiment, two first airbags 4 are provided, and the air outlets 7 of the two first airbags 4 are coaxial.

[0041] The support member 3 is provided with a blocking assembly 8 for sealing the bottom opening of the second airbag 5. This blocking assembly 8 comprises a movable rod 81, with a first blocking block 82 disposed at its top and a second blocking block 83 disposed at its bottom. The first blocking block 82 is used to block the top of the connecting hole 31 and is threadedly connected to the connecting hole 31, securing the movable rod 81 for easy movement. The second blocking block 83 is used to block the bottom opening of the second airbag 5. The movable rod 81 is slidably fitted within the second airbag 5 and the support member 3 along the depth direction of the rebar hole.

[0042] When the second blocking block 83 blocks the bottom opening of the second airbag 5 , the first blocking block 82 also blocks the communicating hole 31 , thereby improving the sealing effect.

[0043] The first blocking block 82 is provided with a first connecting hole 11 connected to the connecting hole 31 and a second connecting hole 12 connected to the connecting hole 10 and the air inlet 6. A vent 9 is provided on the first blocking block 82 for sliding fit. The vent 9 is provided with a connecting hole 10 along the depth direction of the anchor hole. The connecting hole 10 is provided with a first fixing hole connected to the first connecting hole 11 and a second fixing hole connected to the second connecting hole 12. The second fixing hole is positioned higher than the first fixing hole. In this embodiment, when one end of the vent 9 extends out of the first blocking block 82, the first fixing hole is connected to the first connecting hole 11. When the vent 9 is aligned with the first blocking block 82, the second fixing hole is connected to the second connecting hole 12. A blocking member 13 is provided on the connecting hole 10 for blocking the connecting hole 10. The blocking member 13 blocks the opening of the connecting hole 10.

[0044] During installation, the first blocking block 82 is threadedly connected to the connecting hole 31, so that the second blocking block 83 blocks the bottom opening of the second airbag 5, and then one end of the ventilator 9 is extended out of the first blocking block 82, and then the inflation device is used to inflate the ventilator 9, and the gas enters the second airbag 5 through the connecting hole 10, the first connecting hole 11, and the connecting hole 31 to fill the second airbag 5. When the second airbag 5 is inflated, the ventilator 9 is level with the first blocking block 82, so that the air inlet 6 of the first airbag 4 is connected to the second connecting hole 12, and then the inflation device is used to inflate the ventilator 9, and the gas passes through the connecting hole 10, the second connecting hole 12, and the air inlet 6 to fill the first airbag 4. During the expansion of the first airbag 4, due to the restriction of the steel bar, the air outlet 7 is pressed against the outer wall of the second airbag 5 to form a closure, and then the blocking piece 13 is used to seal the connecting hole 10 to complete the installation of the flexible and easily detachable part 1.

[0045] During dismantling, the first blocking block 82 is moved away from the bottom wall of the anchor hole to separate it from the connecting hole 31, and the second blocking block 83 is separated from the bottom opening of the second air bag 5, thereby deflating the second air bag 5. When the second air bag 5 shrinks to above the air outlet 7, the air outlet 7 of the first air bag 4 begins to leak air. In the process of the gas of the first air bag 4 being discharged from the connecting hole 31, the sediment and floating dust in the anchor hole are brought out from the connecting hole 31 together, which not only makes it convenient to dismantle the mold, but also makes it convenient to clean the sediment and floating dust.

[0046] After the first airbag 4 and the second airbag 5 are inflated, the bottoms of the first airbag 4 and the second airbag 5 remain horizontal.

[0047] In other embodiments, the flexible detachable part 1 may be made of plastic, foam or airbag.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
