Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to a dumbbell-shaped pad block and its manufacturing tool that can control slab thickness and support the lowering of slab formwork. Background Technology
[0002] In the construction of cast-in-place floor slabs, the formwork support for the lowered slab areas of bathrooms and kitchens differs from other areas. The forming quality is relatively difficult to control. The suspended formwork method is generally used in areas with height differences. The most obvious difference from other formwork construction is that the bottom is unsupported or fixed in a special way. Generally, it bears lateral loads and needs to be kept stable. This formwork support method is relatively complicated to operate.
[0003] To expedite construction, formwork is typically supported on-site using spacers, which are then secured with wire ties to prevent lateral displacement. Mortar spacers are commonly used in the market, but their use has three significant drawbacks: the small contact area between the mortar spacer and the bottom formwork makes it unstable; the insufficient strength of the mortar spacer, which penetrates the floor slab, inevitably affects the slab's strength; and small local construction joints are formed at the interface between the spacer and the cast-in-place concrete, further increasing the risk of floor slab leakage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dumbbell-shaped pad and its manufacturing tool for controlling slab thickness and supporting the suspended formwork of a lowered slab.
