Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a clamping structure for formwork of reinforced columns in cast-in-place concrete. Background Technology

[0002] Cast-in-place concrete is a type of concrete structure or component that is formed by setting up formwork and pouring concrete on the construction site, followed by curing. This construction method is widely used in building, bridge, and road projects because it has advantages such as high strength, good durability, strong plasticity, and flexible construction. The main purpose of reinforcing column formwork is to prevent the formwork from deforming or shifting during the concrete pouring process, thereby ensuring that the size, position, and shape of the column meet the design requirements.

[0003] For example, a clamping device for cast-in-place concrete reinforced column formwork disclosed in Chinese Patent (Publication No. CN220868807U) is used by placing the left and right clamping plates on the left and right sides of the cast-in-place concrete reinforced column formwork, respectively. The right end of the knob and fixing strip is disassembled, and then the right end of the screw is driven to rotate around the axis of the screw by the knob, so that the entire screw rotates around the axis of the screw. Since the screw thread direction of the left half and the right half of the middle part of the screw are set oppositely, the left and right sliders move closer to each other along the length of the screw. The left and right clamping plates are driven to move closer to each other through the left connecting plate and the left sliding plate, and the right connecting plate and the right sliding plate, respectively, thereby clamping and fixing the cast-in-place concrete reinforced column formwork.

[0004] However, in actual use, the above-mentioned patent still has certain defects: when the reinforcement column formwork is poured, it consists of four sides. When the left and right clamps clamp and fix the reinforcement column formwork, only two sides of the reinforcement column formwork are clamped. Therefore, a clamping structure for cast-in-place concrete reinforcement column formwork is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping structure for formwork of reinforced columns in cast-in-place concrete, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a clamping structure for formwork of reinforced columns of cast-in-place concrete, comprising a first right-angle plate and a second right-angle plate, characterized in that two first right-angle plates are provided, and corresponding second right-angle plates are symmetrically provided on one side of the two first right-angle plates, a first connecting block is installed on each of the two first right-angle plates, a bidirectional threaded rod is provided on the two first connecting blocks, and a second connecting block is installed on each of the two first right-angle plates.

[0007] As a further technical solution of this utility model, a third connecting block is installed on each of the two second right-angle plates, and a strip frame is installed on one end of the two third connecting blocks opposite to the second connecting blocks. A strip rod adapted to the strip frame is installed on the two second connecting blocks.

[0008] As a further technical solution of this utility model, screws are installed on both of the two strip rods, and a strip groove adapted to the screws is provided on one side of the two strip frames. One end of the two screws extends to the outside of the strip frame and is threaded with a nut.

[0009] As a further technical solution of this utility model, each of the two first connecting blocks is provided with a threaded hole adapted to the bidirectional threaded rod, and a first baffle is symmetrically installed on the bidirectional threaded rod.

[0010] As a further technical solution of this utility model, a fourth connecting block is installed on each of the two second right-angle plates, and a connecting rod is provided on the two fourth connecting blocks.

[0011] As a further technical solution of this utility model, each of the two fourth connecting blocks is provided with a connecting hole adapted to the connecting rod, and a second baffle is symmetrically installed on the connecting rod.

[0012] This utility model provides a clamping structure for formwork of reinforced columns in cast-in-place concrete, which has the following advantages compared with the prior art:

[0013] 1. The clamping structure for cast-in-place concrete reinforced column formwork designed in this paper consists of two sets of first right-angled plates and second right-angled plates, with the first right-angled plates and second right-angled plates facing each other and the included angle between their inner sides being right angles. The first right-angled plates and second right-angled plates clamp the reinforced column formwork at the four corner edges of the reinforced column formwork.

[0014] 2. This design includes a clamping structure for reinforced column formwork of cast-in-place concrete. The clamping structure consists of a strip frame, a strip rod, a two-way threaded rod, screws, and nuts. The first right-angle plate and the second right-angle plate are placed and clamped at the four corners of the reinforced column formwork. Rotating the two-way threaded rod can move the two first right-angle plates. Loosening the nuts allows the strip rod to slide on the strip frame, and the distance between the first right-angle plate and the second right-angle plate can be adjusted according to the size of the reinforced column formwork.

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a clamp structure technical solution for cast-in-place concrete reinforced column formwork, including a first right-angle plate 1 and a second right-angle plate 4. Two first right-angle plates 1 are provided, and corresponding second right-angle plates 4 are symmetrically arranged on one side of each first right-angle plate 1. A first connecting block 2 is installed on each of the two first connecting blocks 2, and a bidirectional threaded rod 6 is provided on each of the two first right-angle plates 1. A second connecting block 3 is installed on each of the two first connecting blocks 2, and threaded holes adapted to the bidirectional threaded rod 6 are provided inside each of the two first connecting blocks 2. The first baffle 7 is symmetrically installed on the top. The two first baffles 7 limit the first connecting block 2 to prevent the first connecting block 2 from disengaging from the bidirectional threaded rod 6. The two second right-angle plates 4 are each equipped with a third connecting block 5. When the bidirectional threaded rod 6 is rotated, the two first connecting blocks 2 move outward. When the bidirectional threaded rod 6 is rotated in different directions, the two first connecting blocks 2 move closer to each other or further away from each other on the outside. At the same time, the two first right-angle plates 1 are moved together to adjust the distance between the first right-angle plates 1, so as to make it easy to clamp the outside of the reinforcement column template of different sizes.

[0021] like Figure 2 and Figure 3As shown, two third connecting blocks 5 are equipped with strip frames 11 at their opposite ends to the second connecting blocks 3. Two second connecting blocks 3 are equipped with strip rods 12 that are compatible with the strip frames 11. Screws 13 are installed on both strip rods 12. One side of the two strip frames 11 is provided with a strip groove that is compatible with the screws 13. One end of the two screws 13 extends to the outside of the strip frames 11 and is threaded with a nut 14. Four connecting blocks 8 are installed on both second right-angle plates 4. Connecting rods 9 are provided on both fourth connecting blocks 8. Connecting holes that are compatible with the connecting rods 9 are provided inside both fourth connecting blocks 8. Second baffles 10 are symmetrically installed on the connecting rods 9. When the nut 14 is loosened, the nut 14 no longer abuts against the strip frame 11. The screws 13 slide in the strip grooves on the strip frames 11 to adjust the distance between the two second right-angle plates 4. Then the nut 14 is tightened to abut against the strip frame 11. The second right-angle plates 4 are clamped and fixed on the outside of the reinforced column template.

[0022] The working principle of this utility model is as follows: Rotate the bidirectional threaded rod 6, and the two first connecting blocks 2 move on the outside, which simultaneously drives the two first right angle plates 1 to move together. Adjust the distance between the first right angle plates 1, place the first right angle plates 1 on the outside of the reinforced column template, and then rotate the bidirectional threaded rod 6 in the opposite direction to clamp the first right angle plates 1 on the outside of the reinforced column template. Loosen the nut 14, so that the nut 14 no longer abuts against the strip frame 11, and the screw 13 slides in the strip groove on the strip frame 11. Adjust the distance between the two second right angle plates 4, and then tighten the nut 14 to abut against the strip frame 11. The second right angle plates 4 are clamped and fixed on the outside of the reinforced column template.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
