Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a sealing device for the bottom of aluminum formwork walls used in construction. Background Technology

[0002] In the construction process, various building materials are widely used, including cement, sand, steel bars, and aluminum formwork. Aluminum formwork is highly favored in the construction industry due to its significant advantages such as lightweight and high strength, efficient and precise construction, high reusability, and environmental friendliness. However, because the flatness of the building ground is difficult to achieve ideal, deviations may occur between the bottom of the aluminum formwork and the ground, resulting in gaps at the bottom of the aluminum formwork wall. To prevent grout leakage during concrete pouring, sealing devices are needed to seal these gaps. Currently, existing aluminum formwork wall sealing devices have certain limitations in practical applications:

[0003] Existing methods of sealing joints typically require drilling holes in the aluminum formwork wall, placing the bottom of the sealing device in contact with the building floor, fitting the vertical section against the aluminum formwork wall, inserting a spring into a bolt and passing it through the hole in the aluminum formwork wall, and finally using a nut to secure the sealing device to the aluminum formwork wall. This series of steps is quite complex, increasing the workload of construction workers and potentially affecting construction efficiency.

[0004] Because buildings vary in size, the number of sealing devices needs to be adjusted according to the actual dimensions of the aluminum formwork wall. Specialized splicing components are required to facilitate the splicing of adjacent sealing devices. However, existing splicing methods may suffer from difficulties in splicing and low efficiency, hindering the rapid completion of sealing operations.

[0005] To address these issues, we provide a sealing device for the bottom of aluminum formwork walls used in construction. Utility Model Content

[0006] The purpose of this utility model is to provide a sealing device for the bottom of aluminum formwork walls in construction. By setting an adjustment component, the steps for sealing the bottom of aluminum formwork walls are simplified, reducing the workload. Furthermore, by setting a splicing component, the number of base frames can be increased or decreased according to the size of the aluminum formwork wall, improving practicality and thus solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a wall bottom sealing device for aluminum formwork in construction, comprising a base frame, an adjustment assembly on the base frame, the adjustment assembly including a screw cylinder mounted on the upper surface of the base frame, a top plate rotatably connected to the upper end of a screw shaft internally threaded to the screw cylinder, and a movable plate fixedly fitted onto the lower surface of the top plate inside a groove; the base frame also includes a splicing assembly, the splicing assembly including a positioning plate fixedly attached to the side wall of the base frame, a positioning groove formed in the side wall of the base frame, and the side of the positioning plate away from the positioning groove.

[0009] The present invention is further provided that the side wall of the base frame is provided with a rubber pad, and both the base frame and the rubber pad are L-shaped structures.

[0010] The present invention is further configured such that the upper end of the circumferential side of the screw shaft has a sleeve, and the upper end of the bolt threadedly connected to the lower surface of the sleeve abuts against the lower surface of the top plate.

[0011] The present invention is further configured such that there are symmetrically installed connecting cylinders at two corners of the upper surface of the base frame, and the upper end of the movable shaft sleeved inside the connecting cylinder is installed at the lower corner of the top plate.

[0012] The present invention is further configured such that the outer dimensions of the positioning plate and the inner dimensions of the positioning groove are the same, the positioning plate is an L-shaped structure, and the positioning groove is an L-shaped groove structure.

[0013] The present invention is further configured such that the side wall of the base frame has symmetrically fixed protruding rods, the side wall of the base frame has symmetrically fixed connecting rods, the periphery of the connecting rod has a rotatably connected strip plate, the lower surface of the strip plate has a slot on the side away from the connecting rod, and the protruding rods and the connecting rods are on the same side wall of the base frame.

[0014] The present invention is further configured such that a threaded limiting nut is provided on the periphery of the protruding rod, and the outer diameter of the limiting nut is larger than the inner diameter of the groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting an adjustment component, allows the top plate to move upward or downward by rotating the screw shaft. When the top plate moves upward and abuts against the transverse section of the aluminum formwork wall, the position of the base frame is fixed, and the rubber pad, the building ground, and the aluminum formwork wall surface come into contact, completing the sealing of the bottom of the aluminum formwork wall. When the top plate moves downward, the fixing of the base frame position is released, and the base frame is disassembled. There is no need to use drilling equipment to drill holes in the aluminum formwork wall, which brings convenience to the sealing operation of the bottom of the aluminum formwork wall, simplifies the operation steps, and reduces the workload.

[0017] 2. This utility model sets up a splicing component, inserts the positioning plate on another base frame into the positioning groove on one base frame, rotates the strip plate until the slot is engaged with the protruding rod, and tightens the limiting nut counterclockwise to fix and splice the two adjacent base frames. This makes it convenient to increase or decrease the number of base frames according to the actual size of the aluminum formwork wall, thus improving practicality. Attached Figure Description
