Description

Technical Field

[0001] The utility model relates to an integrated device for sealing and maintaining reserved holes in floor slabs. Background Art

[0002] During the construction of concrete structures of house floors, in order to facilitate the elevation measurement, reserved measuring holes are usually set on the floor slabs, or pump pipe holes are reserved for the arrangement of pump pipes, or holes are reserved on the floor slabs or balcony slabs for passing pipes and arranging flower basket pull rods. The size of these holes is relatively small, but the overall number is often large, usually ranging from 1-2 to more than a dozen per floor. After the main concrete construction is completed, these holes need to be sealed uniformly.

[0003] The traditional method of sealing holes in floor slabs is generally as follows: positioning and laying out → erecting brackets and laying out formwork → hole treatment → base cleaning → steel bar welding → concrete pouring → erecting protective structures → maintenance → removal of formwork and brackets. Since this method of formwork support is troublesome, current hole sealing construction usually uses a simple hanging formwork to pour concrete to seal the reserved holes. However, the quality of the hanging formwork sealing depends largely on the construction quality of the hanging formwork. Due to differences in the operating levels of workers, the survival effects are also different, and it is very likely to cause the sealing to be loose, there is a risk of shrinkage and cracking, and the uneven concrete surface leads to poor visual quality. Moreover, the existing hanging formwork device has fewer hanging holes and the distribution position is fixed. For example, a hanging formwork tool for sealing floor slab holes published in CN115478689A, the water stop screw passes through the hanging rod to install the hanging plate at the lower end of the hole; this will not be able to arbitrarily increase the number of hanging rods or flexibly adjust the position of the hanging rods, so there is a problem of not being suitable for holes of certain sizes. In addition, since the reserved holes on the floor slabs are generally small in size and scattered in location, they are easily overlooked after the concrete is poured, resulting in a lack of maintenance or untimely maintenance of the poured concrete, causing problems such as low strength of the poured concrete and easy cracking, and there is a risk of water seepage in bathrooms, kitchens, balconies and other areas.

[0004] Therefore, how to make the hanging formwork adapt to holes of different sizes, ensure the construction quality of the hanging formwork, ensure timely and meticulous maintenance of the poured concrete, and ensure the quality of sealing the reserved holes are still problems that need to be solved in the building construction process.
