Description

Technical Field

[0001] The utility model belongs to the technical field of building construction support equipment, and in particular relates to a cast-in-place floor slab bottom formwork support device. Background Art

[0002] In building structures, cast-in-place floor refers to a building structure in which the formwork is set up on site, steel bars are installed on the formwork, concrete is poured on the formwork, and then the formwork is removed. Compared with prefabricated floor, cast-in-place floor can enhance the integrity and earthquake resistance of the house and has a greater bearing capacity; it also has certain advantages in terms of heat insulation, sound insulation, waterproofing, etc. Aluminum formwork is widely used in the casting process of building structures as a light, environmentally friendly and strong support system.

[0003] When using aluminum formwork as the bottom formwork of cast-in-place floor slabs, currently, a Mantanghong bracket is usually used for support, that is, the aluminum formwork is supported by the Mantanghong bracket so that it stands on the lower side of the cast-in-place floor slab, thereby playing a supporting role. For example, a utility model patent with authorization announcement number CN210685375U discloses a quick-detachable formwork for cast-in-place slabs between composite floors. A formwork is tightly attached under the cast-in-place slabs between precast concrete composite floors. The formwork is provided with a plurality of keels, and the keels are rectangular square tubes. The bottom surface of the rectangular square tubes is provided with a plurality of groups of limiting circular holes, and each group of the limiting circular holes includes 4 limiting circular holes and are arranged in a square shape. It also includes a plurality of adjustable top supports and a plurality of top support trays, and the top support trays are fixed to the adjustable top supports. At the top, the top support tray at the top of the adjustable top support is provided with 4 limit pins, the arrangement of the limit pins is the same as the arrangement of each group of limit circular holes, and the limit pins on the top support tray of each adjustable top support are respectively inserted into each group of limit circular holes on the keel, and the bottom of the adjustable top support is installed on the supporting steel pipe, and the supporting steel pipe is located on the floor surface. When in use, the adjustable top support is used to adjust the elevation, top the template, and reinforce it firmly, which can effectively control the quality of the cast-in-place slab joints; but when the template structure is in use, there are still problems such as:

[0004] 1. When the formwork structure is in use, the height of the top support tray is adjusted through the adjustable top support so that it acts on the keel and the lower side of the formwork to support the formwork. However, since the lower end of the adjustable top support of the formwork structure is inserted into the top support tray, the height of the formwork cannot be effectively adjusted according to the height of the floor slab variable structure during the adjustment process, thereby realizing the formwork support at multiple heights and multiple deformation nodes, resulting in poor formwork support effect and leakage;

[0005] 2. The template structure is provided with an adjustable top support in the supporting steel pipe, but no corresponding adjustment structure is provided. Therefore, when in use, the position of the adjustable top support in the supporting steel pipe cannot be adjusted as needed to make it suitable for template support under different supporting conditions, resulting in limited adjustment and application range;

[0006] Therefore, the utility model proposes a cast-in-place floor slab bottom formwork supporting device to solve the above-mentioned problems existing in the existing foundation. Utility Model Content
