Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a profiled steel sheet concrete surface floor slab. Background Art
[0002] In industrial plants, the phenomenon of floor stacking loads is relatively common, and the loads are often large, further increasing the load-bearing requirements for the floor. In existing operations, cast-in-place concrete floors are used, which have the defect of increasing the structural self-weight; while using profiled steel sheet floors, on the one hand, the floor flatness is relatively poor, on the other hand, there will be vibration noise during use, and the overall use effect is relatively poor; thirdly, under the action of long-term loads, local deformation is likely to occur, affecting the safety and stability of the overall structure.
[0003] Therefore, there is an urgent need for a floor that can balance the self-weight of the floor slab and the later use effect. Summary of the Invention
[0004] The purpose of the utility model is to provide a profiled steel sheet concrete surface floor slab to overcome the defects existing in the prior art.
[0005] The purpose of the utility model can be realized by the following technical solutions:
[0006] The technical solution of the utility model is to provide a profiled steel sheet concrete surface floor slab, including a plurality of flat steel sheets, reinforcing ribs arranged at the bottom of the steel sheets, steel beams connecting the bottoms of adjacent two steel sheets, and a concrete surface layer arranged on the steel sheets, and a plurality of steel bars are also laid in the concrete surface layer.
[0007] In some specific embodiments, the reinforcing ribs are linear, and one side along its length direction is fixed to the steel sheet.
[0008] In some specific embodiments, the steel beams can be selected from any one or more of I-shaped, box-shaped, and square pipe-shaped, and one side along its parallel line direction is fixed to the steel sheet, or can also be of other types.
[0009] In some specific embodiments, the thickness of the concrete surface layer is 40 mm.
[0010] In some specific embodiments, the concrete surface layer is a C20 concrete surface layer.
[0011] In some specific embodiments, the direction of the steel bars is perpendicular and / or parallel to the direction of the reinforcing ribs.

[0014] In some specific embodiments, the cross-sectional diameter of the steel bars is 6 mm.
[0015] In some specific embodiments, the steel plate is a diamond plate.
[0016] Compared with the prior art, the utility model uses a steel plate and stiffening ribs as the floor bearing structure to bear all the loads during the construction and use stages. At the same time, it serves as the formwork for the concrete surface layer. The concrete surface layer is then poured later as a decorative surface layer to cover the steel plate, ensuring the flatness of the floor after completion, while increasing the floor stiffness and reducing problems such as vibration during the use of the steel plate floor.

[0020] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present utility model, and gives the detailed implementation manners and specific operation processes. However, the protection scope of the present utility model is not limited to the following embodiments.
[0021] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0022] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0023] In the following embodiments, unless otherwise specified for functional components or structures, it means that they are all conventional components or conventional structures adopted in the art to achieve the corresponding functions.
[0024] Embodiment 1:
[0025] As Figure 1 shown, it is a diamond plate concrete surface layer floor slab, including a plurality of flat steel plates 1, stiffening ribs 2 provided at the bottom of the steel plates 1, steel beams 3 connecting the bottoms of adjacent two steel plates 1, and a concrete surface layer 4 provided on the steel plates 1. A plurality of steel bars 5 are also laid in the concrete surface layer 4.
[0026] Exemplarily, the steel plate 1 is a pattern steel plate, which is thin in thickness and light in weight, and can effectively reduce the self-weight of the floor slab; in terms of load-bearing capacity, the thin pattern steel plate has relatively high structural strength when combined with stiffeners, and can bear a large load, making it suitable for floors that need to bear heavy objects; in terms of impact resistance, the pattern steel plate has good elasticity and toughness, can withstand a certain degree of impact force, and reduce damage caused by impact; in terms of durability, under normal use and maintenance conditions, the pattern steel plate has a long service life, reducing the frequency of replacement and repair.
[0027] During installation, in order to enhance the support of the pattern steel plate and the stiffness of the structure, the stiffener 2 is linear, and one side along its length is fixed to the steel plate 1. When connecting two adjacent pattern steel plates, the steel beam 3 used is preferably I-shaped, and one side along its parallel direction is fixed to the pattern steel plate. Other types such as box-shaped and square pipe-shaped can also be selected.
[0028] The concrete surface layer 4 laid on the pattern steel plate is finely leveled and smoothed, which can provide a more flat surface and improve the flatness of the pattern steel plate. The thickness of the concrete surface layer 4 is 40 mm, which is a C20 concrete surface layer. The C20 concrete surface layer means that the compressive strength of the concrete in the concrete surface layer is 20 MPa, indicating that after this concrete is cured for 28 days under standard conditions, the average value of its cube compressive strength is about 20 MPa. The C20 concrete surface layer has relatively high compressive strength, can bear various loads in daily use; can resist wear, and is suitable for places with large flow of people and logistics; under normal maintenance conditions, it has a long service life and is not easily damaged; the construction is simple, can be cast on site according to needs, and adapts to various complex building structures; has good fire resistance, which helps to improve the safety of the building; and does not produce harmful substances during use, being environmentally friendly. In short, the C20 concrete surface layer is a cost-effective option.
[0029] The steel bars 5 are also laid in the concrete surface layer 4 along the longitudinal and transverse directions. The directions of the steel bars 5 are also perpendicular and parallel to the direction of the stiffener 2. As the crack-resistant steel bars of the concrete surface layer 4, they also enhance the stability and stiffness of the floor slab in the transverse and longitudinal directions respectively. Exemplarily, the cross-sectional diameter of the steel bars 5 is 6 mm, and the spacing between two adjacent steel bars 5 is 150 mm.
[0030] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the utility model. Those familiar with the technology in this field can obviously make various modifications to these embodiments easily, and apply the general principles described herein to other embodiments without creative labor. Therefore, the present utility model is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art according to the disclosure of the present utility model without departing from the scope of the present utility model should be within the protection scope of the present utility model.
