Description

TECHNICAL FIELD

[0001] The utility model relates to ground panel technical field, especially in an integrated composite ground panel for light steel structure and floor structure. BACKGROUND

[0002] The ground panel is a structure for transmitting load to building load bearing components (such as beams, columns or walls), the existing ground panel generally includes structural layer, leveling layer, functional layer (sound insulation layer, thermal insulation layer or floor heating etc.), finish layer from bottom to top, but the existing ground panel mostly takes concrete floor slab as structural layer, and ceramic tile manufactured by sintering process as finish layer, so there are at least the following deficiencies:

[0003] 1. Concrete floor slab needs to be cast on site, which is heavy in weight, long in construction period, and high in load bearing requirement for main structure, mainly suitable for reinforced concrete building structure, and difficult to be applied to light steel structure.

[0004] 2. The ground panel has many structural levels, and needs to be constructed layer by layer from bottom to top, which is time-consuming and laborious.

[0005] 3. The ground panel is a brittle material, which has small bending strength and is easy to crack and break due to bumping, resulting in the need to replace the ground panel and increase the construction cost.

[0006] 4. The ground panel is a monolithic structure after construction, and needs to be re-constructed after the damaged part and the adjacent area are excavated, which is difficult and costly for local maintenance.

[0007] 5. The finish layer is limited in selection by sintering process, and is difficult to meet the increasingly rich needs of users.

[0008] Therefore, in view of the deficiencies of the existing ground panel, a new type of ground panel suitable for light steel structure needs to be developed. UTILITY MODEL CONTENT

[0009] The utility model aims at overcoming the technical problems that the ground panel in the prior art adopts a multi-layer structure including concrete floor slab, resulting in that the ground panel is too heavy in weight and difficult to be applied to light steel structure, and time-consuming and laborious in construction, and provides an integrated composite ground panel for light steel structure and floor structure.

[0010] In the first aspect, the utility model provides an integrated composite ground panel for light steel structure, which comprises a direction adjusting mechanism, a bottom plate, a keel frame, a fiber composite board and a wear-resistant layer arranged in sequence.

[0011] The azimuth adjusting mechanism comprises a first connecting plate, a second connecting plate and a connecting bolt; the first connecting plate is connected with the bottom plate, and the first connecting plate is provided with a first waist-shaped hole; the second connecting plate is used for being connected with the main body steel beam, and the second connecting plate is provided with a second waist-shaped hole;

[0012] The length of one of the first waist-shaped hole and the second waist-shaped hole is arranged along the thickness direction of the bottom plate, and the length direction of the first waist-shaped hole and the length direction of the second waist-shaped hole are perpendicular to each other; the connecting bolt passes through the first waist-shaped hole and the second waist-shaped hole to connect the first connecting plate and the second connecting plate.

[0013] Compared with the existing ground plate, the main stress structure of the integrated composite ground plate applied to the light steel structure in the scheme is a combined structure comprising a bottom plate, a keel frame and a fiber composite plate. The combined structure has a higher strength-weight ratio than a concrete floor, can ensure that the scheme has sufficient bearing capacity and rigidity, and at the same time, makes the scheme have a lighter weight than the existing ground plate, so as to be compatible with the light steel structure. The azimuth adjusting mechanism enables the scheme to adjust the position along the first waist-shaped hole and the second waist-shaped hole in two directions relative to the main body steel beam, thereby realizing functions such as leveling, height adjustment, horizontal position adjustment and the like.

[0014] Meanwhile, the combined structure composed of the bottom plate, the keel frame and the fiber composite plate has higher ductility than the concrete floor, and is not prone to cracking and breaking due to bumps, thereby being able to reduce additional material consumption during construction and reduce construction cost.

[0016] The scheme also uses a combination of a fiber composite plate and a wear-resistant layer instead of a ceramic facing layer in the existing ground plate, which not only ensures the wear resistance of the scheme through the wear-resistant layer, but also avoids the limitation of the sintering process by using the fiber composite plate, and can freely select the material, size, cross-sectional shape and the like of the fiber composite plate according to the user's needs, having more flexible selectivity.

[0017] Preferably, a thermal insulation and sound insulation filler is also filled between the bottom plate and the fiber composite plate.

[0025] Preferably, the bottom plate is an aluminum veneer.

[0026] The scheme recommends using an aluminum veneer as the bottom plate. The aluminum veneer is light in weight, high in strength, and has strong corrosion resistance, which can reduce the weight of the bottom plate while maintaining the strength and ensuring the service life of the bottom plate. The aluminum veneer also has certain sound absorption properties, which can improve the sound insulation performance of the scheme together with the heat preservation and sound insulation filler.

[0027] Preferably, the surface of the bottom plate is passivated.

[0028] The scheme recommends passivating the surface of the bottom plate, which can improve the corrosion resistance of the bottom plate and thereby ensure the service life of the bottom plate.

[0029] Preferably, the bottom plate and the keel frame are connected by screws, and / or the fiber composite board and the keel frame are connected by screws.

[0030] The scheme can quickly and reliably connect the bottom plate and the keel frame, and the fiber composite board and the keel frame.

[0031] In the second aspect, the utility model provides a floor structure, including at least two the utility model discloses a kind of integrated composite floor applied to light steel structure, and the side wall of adjacent two integrated composite floor applied to light steel structure is mutually spliced.

[0032] The floor structure of the scheme is spliced by at least two integrated composite floor applied to light steel structure of the utility model, on the one hand, due to the light self-weight and integrated structural design of the floor, the scheme can be applied to light steel structure and realize rapid construction. On the other hand, when local damage occurs, the damaged floor can be individually disassembled and replaced, thereby realizing rapid and efficient repair of the floor structure.
