Description

Technical Field

[0001] This utility model belongs to the field of rebar positioning technology, specifically relating to a rebar positioning device for concrete columns. Background Technology

[0002] Concrete columns are building components made of materials such as cement, steel bars, sand, gravel, and water, and are widely used in construction, transportation, and other fields.

[0003] Concrete columns are generally constructed by casting. Before casting, foundation treatment is required, including removing debris and dirt from the foundation surface and constructing a leveling layer to ensure the foundation's load-bearing capacity and stability, meeting the column installation requirements. Rust and cement slurry on the embedded reinforcing bars must be removed. According to design requirements, the reinforcing bars are hoisted into place and welded or tied to form a reinforcing bar skeleton, ensuring the skeleton's position does not deviate from the column's center. Smooth-surfaced formwork with the required verticality is selected, and the joints between formwork panels should be tight, flat, and leak-proof. After formwork installation, adjustments are made to ensure the column's verticality. During casting, suitable concrete materials are selected, and the mix proportions are verified. Before casting, the formwork joints are specially inspected, and proper grouting is performed between new and old concrete. Casting is done in layers, with each layer controlled to a thickness of 30cm. On the left and right sides, use an immersion vibrator to compact the concrete to ensure it is dense. After pouring, the concrete on the top surface of the column should be cured. This can be done by a combination of watering and covering with soil. The number of times water is sprinkled each day should be enough to keep the concrete surface moist. The curing time depends on the type of concrete and environmental conditions, but should generally be no less than 7 days.

[0004] Before pouring concrete columns, a steel reinforcement cage needs to be pre-embedded. During pre-embedding, it is necessary to ensure that the size and position of the steel reinforcement cage meet the construction standards, which means that the steel reinforcement cage needs to be positioned. Currently, the commonly used positioning method is to use external positioning devices to position the steel reinforcement cage. After the steel reinforcement cage is constructed, the external positioning devices need to be removed, which reduces construction efficiency. Therefore, a steel reinforcement positioning device for concrete columns is needed, which can directly position the steel reinforcement cage without removal, thereby improving construction efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem that external positioning components still need to be removed after the construction of the steel reinforcement cage, which reduces construction efficiency. This invention proposes a steel reinforcement positioning device for concrete columns that can directly position the steel reinforcement cage without removal, thereby improving construction efficiency.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a rebar positioning device for concrete columns, comprising four rebar hoops arranged in a 4×4 rectangle, with a connector between any two adjacent rebar hoops. A locking block is fixed to the side of the rebar hoop away from the connector. In use, the device is first placed at the location where the rebar skeleton needs to be installed. Then, auxiliary positioning components, such as laser positioning devices or spirit levels, are engaged with the locking blocks to ensure the accuracy of the device's position. The rebar is then inserted into the four rebar hoops and fixed by the hoops. Subsequently, the device is reinstalled at a certain height until the rebar skeleton is completed. After confirming the position of the rebar skeleton is correct using the auxiliary positioning components, the auxiliary positioning components are removed, completing the construction of the rebar skeleton. Concrete can then be poured directly without disassembling the positioning device, effectively improving the construction efficiency of concrete columns and providing good overall performance.

[0007] Furthermore, the connector includes a female plate and a male plate, with the male plate inserted into the female plate and slidably connected. Through the slidably connected female and male plates, the distance between two adjacent steel reinforcement hoops can be adjusted, making the device suitable for steel reinforcement cages of different sizes.

[0008] Furthermore, elongated holes are provided on the sides of both the female plate and the male plate, and fastening bolts are installed inside the elongated holes. The fastening bolts pass through the female plate and the male plate, and the female plate and the male plate can be fixed by the fastening bolts.

[0009] Furthermore, a laser locator or a level is attached to the block, which can be used to assist in the positioning of the steel reinforcement cage.

[0010] Furthermore, the steel reinforcement hoops are retractable clamps, which facilitate the use of steel reinforcement of various specifications.

[0011] Furthermore, a rubber pad is bonded to the inside of the rebar hoop. The rubber pad increases the friction of the rebar hoop and prevents it from slipping.

[0012] As can be seen from the above technical solutions, this utility model has the following advantages:

[0013] By placing the device at the location where the reinforcing steel frame needs to be installed, and then attaching auxiliary positioning components such as laser locators and spirit levels to the locking blocks to ensure the accuracy of the device's position, the reinforcing steel is inserted into the four steel hoops and fixed in place. The device is then reinstalled at a certain height until the reinforcing steel frame is completed. After confirming the position of the reinforcing steel frame is correct using the auxiliary positioning components, the auxiliary positioning components are removed, completing the construction of the reinforcing steel frame. Concrete can then be poured directly without disassembling the positioning device, effectively improving the construction efficiency of concrete columns and resulting in good overall performance.

The rebar hoops 1 are retractable clamps, which facilitate the use of rebars of various specifications. Rubber pads are adhered to the inner side of each rebar hoop 1 to increase friction and prevent slippage. The four rebar hoops 1 are arranged in a 4×4 rectangle. A connector 2 is provided between any two adjacent rebar hoops 1. A locking block 3 is fixed to the side of each rebar hoop 1 away from the connector 2. A laser locator or a level is attached to the locking block 3, allowing for precise positioning of the rebar cage. The positioning aid is used by first placing the device at the location where the steel reinforcement frame needs to be installed. Then, auxiliary positioning components, such as laser positioning devices or spirit levels, are attached to the locking blocks to ensure the accuracy of the device's position. The steel reinforcement is then inserted into the four steel reinforcement hoops 1 and fixed using the hoops 1. The device is then reinstalled at a certain height until the steel reinforcement frame is erected. After confirming the position of the steel reinforcement frame is correct using the auxiliary positioning components, the auxiliary positioning components are removed, completing the erection of the steel reinforcement frame. Concrete can then be poured directly without disassembling the positioning device, effectively improving the construction efficiency of concrete columns and providing good overall performance.

[0020] Specifically, the connector 2 includes a female plate 4 and a male plate 5. The male plate 5 is inserted into the female plate 4 and slidably connected. Through the sliding connection of the female plate 4 and the male plate 5, the distance between two adjacent steel reinforcement hoops 1 can be adjusted, making the device suitable for steel reinforcement cages of different sizes. Both the female plate 4 and the male plate 5 have elongated holes 6 on their sides. Fastening bolts 7 are installed inside the elongated holes 6. The fastening bolts 7 pass through the female plate 4 and the male plate 5, and can fix the female plate 4 and the male plate 5 through the fastening bolts 7.
