Description

Technical Field

[0001] This utility model relates to the field of beam and column casting formwork reinforcement technology, and in particular to a beam and column casting formwork reinforcement component for increasing the cross-section of a building. Background Technology

[0002] Enlarging the cross-section of a building is a common structural reinforcement method. It mainly involves adding a new layer of reinforced concrete around the existing beams and columns to enhance their compressive, shear, and bending resistance.

[0003] This method involves adding new reinforced concrete to the outside of existing beams and columns, followed by the installation of beam and column casting formwork on the outside. Concrete is then poured inside. After the casting formwork is installed, reinforcement components need to be installed on the outside to increase its stability. However, existing reinforcement components can only be used for beam and column casting formwork of fixed sizes. This means that after removing reinforcement components used on smaller beam and column casting formwork, they cannot be used on larger ones. Because the dimensions of beams, columns, and casting formwork vary across different construction projects, workers need to measure multiple beam and column dimensions and customize various specifications of reinforcement components accordingly. Customizing reinforcement components incurs additional time costs, affecting project progress. Furthermore, preparing multiple different specifications of reinforcement components during the project increases workload. Due to the diversity of beam and column casting formwork dimensions across different projects, reinforcement components can only be used on specific sizes. When changing projects, if the beam and column casting formwork dimensions are different, the reinforcement components from previous projects cannot be used, resulting in wasted design resources. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a beam and column casting formwork reinforcement component for increasing the cross-section of buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A beam and column casting formwork reinforcement component for reinforcing the cross-section of a building includes a fixed rod. A first connecting rod is movably installed on one side of the fixed rod. A first rotating rod is movably connected to the end of the first connecting rod away from the fixed rod. A second connecting rod is movably installed on the same side of the fixed rod as the first connecting rod. The first and second connecting rods are symmetrically arranged.

A movable rod is inserted into the second slot of both the first and second rotating rods. An auxiliary mechanism is provided at the end of both the first and second rotating rods away from the fixed rod.

[0007] Preferably, the fixing rod has a first slot on the side near the first connecting rod and the second connecting rod, and a bidirectional threaded rod is rotatably installed inside the first slot.

[0010] Preferably, the auxiliary mechanism includes a fixed block, a second handle, and a one-way threaded rod. The first rotating rod and the second rotating rod are each equipped with a fixed block at the end away from the fixed rod. A one-way threaded rod is threaded through the fixed block. An abutment block is installed at the end of the one-way threaded rod facing the fixed rod. The fixed block is provided with a second handle on the side away from the fixed rod. The end of the one-way threaded rod near the second handle is threaded through the fixed block and connected to the second handle.

[0011] Preferably, the movable rod has two third slots on the side away from the fixed rod, and a sliding block is slidably installed inside the third slot.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-7A beam and column casting formwork reinforcement component for reinforcing the cross-section of a building includes a fixed rod 2. A first connecting rod 3 is movably installed on one side of the fixed rod 2. A first rotating rod 4 is movably connected to the end of the first connecting rod 3 away from the fixed rod 2. A second connecting rod 16 is movably installed on the same side of the fixed rod 2 as the first connecting rod 3. The first connecting rod 3 and the second connecting rod 16 are symmetrically arranged. A second rotating rod 6 is movably connected to the end of the second connecting rod 16 away from the fixed rod 2. Both the first rotating rod 4 and the second rotating rod 6 have a second slot 12. A movable rod 5 is inserted into the second slot 12 on both the first rotating rod 4 and the second rotating rod 6. An auxiliary mechanism is provided at the end of both the first rotating rod 4 and the second rotating rod 6 away from the fixed rod 2. By tightening the fixed rod 2, the movable rod 5, the first connecting rod 3, the first rotating rod 4, the second connecting rod 16, and the second rotating rod 6, the outer casting slab of the beam and column body 1 can be tightened. The auxiliary mechanism can achieve the tightening and abutment of the movable rod 5.

[0026] As a technical optimization of this utility model, a first slot 7 is provided on the side of the fixed rod 2 near the first connecting rod 3 and the second connecting rod 16. A bidirectional threaded rod 8 is rotatably installed inside the first slot 7. A first handle 11 is installed at one end of the fixed rod 2. The connecting part on the first handle 11 passes through the end wall of the fixed rod 2 and connects to the bidirectional threaded rod 8. A second slider 10 is connected to the end of the first connecting rod 3 near the fixed rod 2. The bidirectional threaded rod 8 is threaded through the second slider 10. A first slider 9 is connected to the end of the second connecting rod 16 near the fixed rod 2. The bidirectional threaded rod 8 is threaded through the first slider 9. By turning the first handle 11, the bidirectional threaded rod 8 is rotated, thereby causing the first slider 9 and the second slider 10 to slide inside the first slot 7. This allows the first connecting rod 3 and the second connecting rod 16 to move closer to or further away from each other. Through this operation, the positions of the first connecting rod 3 and the second connecting rod 16 can be adjusted according to the beam-column body 1 of different sizes.

[0027] As a technical optimization of this utility model, a second connecting groove 25 is provided at the end of the first connecting rod 3 near the first rotating rod 4. A second rotating block 26 is rotatably installed inside the second connecting groove 25, and the side of the second rotating block 26 near the first rotating rod 4 is connected to the first rotating rod 4. By rotating the second rotating block 26 in the second connecting groove 25, the first rotating rod 4 can be folded and stored when the device is not in use.

[0028] As a technical optimization of this utility model, a first connecting groove 17 is provided at the end of the second connecting rod 16 near the second rotating rod 6. A first rotating block 18 is rotatably installed inside the first connecting groove 17, and the side of the first rotating block 18 near the second rotating rod 6 is connected to the second rotating rod 6. By rotating the first rotating block 18 in the first connecting groove 17, the second rotating rod 6 can be folded and stored when the device is not in use.

[0029] As a technical optimization of this utility model, the auxiliary mechanism includes a fixed block 13, a second handle 14, and a one-way threaded rod 15. The first rotating rod 4 and the second rotating rod 6 are both equipped with a fixed block 13 at their ends away from the fixed rod 2. A one-way threaded rod 15 is threaded through the fixed block 13. An abutment block 19 is installed at the end of the one-way threaded rod 15 facing the fixed rod 2. The second handle 14 is located on the side of the fixed block 13 away from the fixed rod 2. The end of the one-way threaded rod 15 near the second handle 14 is threaded through the fixed block 13 and connected to the second handle 14. By turning the second handle 14, the one-way threaded rod 15 can extend and retract to different distances within the second slot 12.

[0030] As a technical optimization of this utility model, two third slots 20 are provided on the side of the movable rod 5 away from the fixed rod 2. A sliding block 23 is slidably installed inside the third slot 20. An abutment groove 24 is provided on the side of the sliding block 23 away from the fixed rod 2. The abutment block 19 can be inserted into the abutment groove 24. The way the abutment block 19 is inserted into the abutment groove 24 makes the connection between the one-way threaded rod 15 and the movable rod 5 more stable. The sliding block 23 can also slide, so that the movable rod 5 can be adjusted to the corresponding size according to the different beam and column body 1 dimensions.

[0031] As a technical optimization of this utility model, a trapezoidal groove 21 is provided at the bottom of the inner wall of the third slot 20. A trapezoidal slider 22 is connected to the side of the sliding block 23 near the trapezoidal groove 21, and the trapezoidal slider 22 is slidably installed inside the trapezoidal groove 21. By allowing the trapezoidal slider 22 to slide in the trapezoidal groove 21, the sliding stability of the sliding block 23 inside the third slot 20 can be increased.

[0032] When this utility model is in use and reinforcement of the cast-in-place slab on the outside of the beam-column body 1 is required, after the cast-in-place slab is installed on the outside of the beam-column body 1, this device... Figure 1 The device is installed on the outside of the beam-column body 1 to fix the cast-in-place slab on the outside of the beam-column body 1. Then, multiple of these devices are installed on the outside of the beam-column body 1 to complete the stable reinforcement of the cast-in-place slab on the outside of the beam-column body 1.

[0033] The installation method of this device is as follows: Based on the dimensions of the cast-in-place slab on the outer side of the beam-column body 1, the operator first turns the first handle 11 to rotate the bidirectional threaded rod 8, causing the first slider 9 and the second slider 10 to slide inside the first slot 7. This allows the first connecting rod 3 and the second connecting rod 16 to move closer or further apart. Through this operation, the positions of the first connecting rod 3 and the second connecting rod 16 can be adjusted according to the different sizes of the cast-in-place slab on the outer side of the beam-column body 1. At this time, the device is... Figure 3 The diagram shows the usage state without the movable rod 5 installed. The adjusted device is then fitted onto the outside of the cast-in-place slab on the outside of the beam-column body 1, so that the fixed rod 2, first connecting rod 3, first rotating rod 4, second rotating rod 6, and second connecting rod 16 all abut against the side wall of the cast-in-place slab on the outside of the beam-column body 1. The worker then removes the movable rod 5 and arranges it according to… Figure 2 The first rotating rod 4 and the second rotating rod 6 are inserted into the second slot 12 as shown. Then, the worker slides the sliding block 23 to make the abutment groove 24 slide to the position aligned with the abutment block 19. Then, the worker turns the second handle 14 to make the one-way threaded rod 15 move towards the movable rod 5. After the abutment block 19 is inserted into the abutment groove 24, the worker continues to turn the second handle 14 to push the movable rod 5 until the movable rod 5 abuts against the side wall of the cast slab on the outside of the beam-column body 1. This operation method can complete the fixation of the cast slab on the outside of the beam-column body 1.

[0034] This device allows for sliding adjustment on the fixed rod 2 via the first connecting rod 3 and the second connecting rod 16, and the sliding block 23 can be adjusted inside the third slot 20. This enables the device to automatically adjust the size of the cast-in-place slabs on the outside of beam-column bodies 1 of different sizes, thus increasing the practicality of the device.

[0035] When the device is not in use, remove the movable rod 5 from the device. Then, by turning the first handle 11, the first connecting rod 3 and the second connecting rod 16 move away from each other and move to the preset usage position. Then, the operator rotates the second rotating rod 6 so that the second rotating rod 6 rotates toward the fixed rod 2 until the second rotating rod 6 rotates to a usage state parallel to the fixed rod 2. Then, the operator rotates the first rotating rod 4 so that the first rotating rod 4 rotates toward the fixed rod 2 until the first rotating rod 4 rotates to a usage state parallel to the fixed rod 2. In this way, the device can be folded and stored, reducing the space occupied by the device and facilitating the transportation and storage of the device. Since the length of the first connecting rod 3 is greater than the length of the second connecting rod 16, the first rotating rod 4 can be folded on the outside of the second rotating rod 6 after the second rotating rod 6 is folded.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
