Description

A lightweight floor laminate

technical field

The utility model relates to a building component, in particular to a light-duty floor composite board used in various industrial and civil buildings.

Background technique

At present, in construction engineering, most of the floor structure of the building is made of templates to form a mold base, steel bars are laid in the mold base, and then concrete is poured on site to complete the production of the floor structure. The surface is poured at one time, so that the floor is formed at one time, which not only increases the strength of the floor, but also prevents problems such as cracking of the floor. Time for on-site maintenance not only wastes a lot of manpower and material resources, but also delays the normal progress of other work.

Contents of the invention

The purpose of this utility model is to overcome the deficiencies of the above technologies, and provide a light-duty floor laminate that saves a lot of templates, facilitates on-site construction, and improves construction efficiency.

The utility model is realized by adopting the following technical solutions: a light-duty floor laminated slab, comprising a prestressed concrete thin slab with a rectangular cross-section, characterized in that: the upper surface of the concrete thin slab is provided with a number of superimposed pins.

When performing on-site concrete pouring, the superimposed pins are used to tightly combine the concrete layer and the concrete thin slab into one, increasing the strength of the floor.

Below is the further improvement of the utility model to above technical scheme:

The cross-sectional shape of the superimposed pin key is dovetail groove shape, so that the concrete layer and the concrete thin slab are closely integrated, and the strength of the floor is further enhanced.

The two sides of the concrete thin slabs are sloped. When concrete is poured on site, concrete mortar is filled between the side-by-side concrete thin slabs, so that the side-by-side concrete thin slabs are closely connected together, and the bond between the side-by-side concrete thin slabs and the concrete layer is strengthened. Binding force.

The thin concrete slab is provided with a number of steel bars for skeleton, which increases the stress resistance and tensile strength of the thin concrete slab, prevents fracture and cracking of the floor after forming, and enhances the strength of the floor.

Beneficial effect:

The utility model can be prefabricated in advance in batches in the workshop according to the construction requirements. When the floor is being constructed, the utility model can be arranged side by side on the building supports, and then the on-site concrete layer can be poured according to the thickness required by the floor. The new type is closely combined with the concrete layer and becomes a part of the floor, which not only replaces the function of the formwork, but also improves the construction efficiency and reduces the labor intensity. It has good practical value and promotion value.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Accompanying drawing 2 is the top view of the utility model embodiment;

Accompanying drawing 3 is the structure schematic diagram after on-site construction of the utility model embodiment.

Detailed ways

Embodiment, as shown in Fig. 1, Fig. 2, a kind of light-duty floor composite slab, comprises the prestressed concrete sheet 1 that section is rectangular, and the upper surface of described concrete sheet 1 is provided with several superimposed pin keys 2, as shown in Fig. 3, when performing on-site concrete pouring, the superimposed pin key 2 tightly integrates the concrete layer 5 and the concrete sheet 1, which increases the strength of the floor. The cross-sectional shape of the superimposed pin key 2 is a dovetail groove shape , which further enhances the strength of the floor. The two sides of the concrete thin slabs 1 are inclined surfaces 3. When performing on-site concrete pouring, concrete mortar is filled between the side-by-side concrete thin slabs 1, even if the side-by-side concrete thin slabs are closely connected together. , strengthened the binding force of the side by side concrete sheets 1 and the concrete layer 5, and said concrete sheets 1 are provided with several steel bars 4 used as skeletons, which not only increased the stress resistance and tensile strength of the concrete sheets 1, but also prevented The fracture and slit of the floor after forming are eliminated, and the strength of the floor is enhanced.

The utility model can be prefabricated in advance in batches in the workshop according to the construction requirements. When the floor is being constructed, the utility model can be arranged side by side on the building supports, and then the on-site concrete layer can be poured according to the thickness required by the floor. The new type is closely combined with the concrete layer and becomes a part of the floor, which not only replaces the function of the formwork, but also improves the construction efficiency and reduces the labor intensity. It has good practical value and promotion value.
