Description

Technical Field

[0001] The invention relates to the field of aluminum mold plugging structures, and in particular to an aluminum mold lower corner adjustable plugging-free system and a construction method thereof. Background Art

[0002] In the existing technology, the installation and removal dimensions of the aluminum formwork are designed in advance. However, since the floor surface may be uneven, in order to prevent leakage at the root of the wall column, it is usually necessary to use concrete, mortar or specific sealing materials to seal the shear wall formwork feet of the aluminum formwork by manual filling and compaction. Although this method has certain flexibility, its sealing quality depends largely on the technical level and attitude of the workers, so there is a certain degree of quality instability. In the construction process using aluminum formwork, the gap sealing and molding quality at the root of the aluminum formwork wall column is a technical issue.

[0003] Conventional methods for sealing the lower corners of aluminum molds: ① Mortar sealing. Use dry and hard micro-expansive cement mortar to fill the gap at the root of the aluminum mold and compact it to form a seal. ② Angle steel or rubber strip sealing. Install angle steel or rubber strips at the bottom of the aluminum mold and fix them with bolts to achieve sealing.

[0004] Disadvantages of existing technology:

[0005] (1) High material loss rate. Cement mortar plugging is a disposable material that cannot be used or recycled, and has a high loss rate. Rubber strips are prone to aging and deformation, resulting in loss of sealing performance. They are easily lost or damaged after removal, and have a low turnover rate.

[0006] (2) Poor adaptability. Angle steel and rubber strips have poor adjustability. When the flatness of the floor is poor, they cannot be accurately adapted and adjusted. The sealing is poor, which can easily cause leakage. At the same time, the aluminum mold is forced to be raised due to the uneven floor, which can easily cause the net height of the floor to be too large and increase the investment in construction materials.

[0007] (3) The construction process is complicated. The cement mortar plugging process is complicated, and manual chiseling and cleaning are required later; the fixing process of angle steel or rubber strip plugging is relatively complicated, and after installation, the bolts still need to be tightened and checked and adjusted to ensure the quality of the plugging;

[0008] (4) Unstable plugging quality. The efficiency of cement mortar plugging construction is low and is easily affected by the construction environment and the technical level of workers, resulting in unstable plugging quality. Therefore, it is necessary to design an aluminum mold lower corner adjustable plugging-free system and its construction method. Summary of the invention

[0009] The purpose of the present invention is to provide an adjustable plugging-free system for the lower corner of an aluminum mold and a construction method thereof, so as to solve the technical problems of low turnover times, inability to accurately adjust, and complicated construction procedures in traditional plugging methods for the lower corners of aluminum molds, and effectively avoid poor plugging quality and increased construction costs.

The up-and-down moving device is arranged in contact with the upper end of the floor slab due to the action of gravity, so that the aluminum mold does not need to be provided with an additional blocking structure.

[0012] Furthermore, the angle steel and the aluminum mold are fixedly connected by bolts, and the inner side of the angle steel is arranged flush with the aluminum mold.

[0013] Furthermore, the up-and-down moving device is configured as a steel plate, and the steel plate is configured to be movable up and down on the outside of the angle steel.

[0018] Furthermore, the up-and-down moving device includes a plurality of steel plates, each of which is provided with an elliptical opening, and bolts are provided to pass through the elliptical opening and be fixed on the steel plate, so that the steel plate can be moved up and down.
