Technical Field

[0001] A stepped independent foundation green construction formwork component belongs to the field of building independent foundation formwork technology. Background Technology

[0002] In engineering construction, especially in industrial plant projects, stepped foundations are widely used. Traditionally, stepped independent foundations are constructed by setting up formwork and pouring concrete in stages, then setting up formwork and pouring the next layer of concrete after the concrete has reached the required strength. This construction process is time-consuming, and the independent foundation involves multiple pours, resulting in poor overall integrity and difficulty in controlling construction quality. To accelerate construction and ensure the quality of the stepped foundation concrete, a novel formwork device for independent foundations needs to be designed to improve standardized construction, shorten the construction cycle, save construction costs, and enhance the overall quality of independent foundation construction. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a stepped independent foundation green construction formwork component that can be reinforced according to the size adjustment of the stepped foundation concrete.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: The stepped independent foundation green construction formwork component includes an adjusting clip, a middle connecting rod, an end connecting rod, and a fixing rod. The adjusting clip is engaged at the four corners of the upper step, and the two sides of the engaged corner are respectively connected to the middle connecting rods set on the four sides of the upper step. The two sides opposite the engaged corner of the adjusting clip are connected to the end connecting rods. The overlapping parts of the middle connecting rod and the two sides of the adjusting clip, and the overlapping parts of the end connecting rod and the other two sides of the adjusting clip are fixed by fixing parts. The fixing rod is set on the four sides of the lower step, and its two ends are respectively connected to the ground and the end connecting rods.

[0005] Preferably, the adjusting clamp includes two horizontal bars, two vertical bars, and a connector. The two horizontal bars are horizontally symmetrically arranged on both sides of the connector, and the two vertical bars are vertically symmetrically arranged on the other two sides of the connector. The horizontal bars and vertical bars at the locking angle are connected to the middle connecting rod, and the horizontal bars and vertical bars at the opposite angles are connected to the end connecting rods.

[0006] Preferably, the middle connecting rod and the end connecting rod are hollow inside and are respectively fitted onto the horizontal bar and the vertical bar; or the horizontal bar and the vertical bar are hollow inside and are respectively fitted onto the middle connecting rod and the end connecting rod.

[0007] Preferably, the fastener is a bolt, and both the intermediate connecting rod and the end connecting rod are provided with adjusting bolt holes. The adjusting clip is fixedly connected by bolts set in the adjusting bolt holes.

[0008] Preferably, the fixing rod is vertically riveted to the end connecting rod, and forms a vertical engagement angle with the end connecting rod to engage the lower step.

[0009] Preferably, it also includes a diagonal brace, which is inclinedly arranged between the end connecting rod and the fixed rod.

[0010] Preferably, it also includes a template, which is placed between the lower step, the upper step and the reinforcing device, and the reinforcing device presses the template to fit the lower step and the upper step respectively.

[0011] Compared with existing technologies, the beneficial effects of this technical solution are: This invention features adjustable clips at the four corners of the upper step, a central connecting rod that presses against the upper step and connects to the adjustable clips, and fixed rods positioned on the four sides of the lower step that press against the lower step and connect to end connecting rods, which in turn connect to the adjustable clips. The overlapping portions of the central connecting rod, end connecting rods, and adjustable clips are fixed by fasteners. When the reinforcement device needs to be adjusted according to the dimensions of the lower or upper step, only the length of the overlapping portion of the central connecting rod and the adjustable clip, or the length of the overlapping portion of the end connecting rod and the adjustable clip, needs to be adjusted. After adjustment, it is fixed by fasteners. The operation is simple, which not only improves construction efficiency but also reduces material waste and lowers construction costs.
