Description

Concave-convex plate-type coagulation composite structure

The invention relates to a coagulation composite structure composed of a concave-convex plate as a skeleton, in particular to a plurality of shapes extending from the concave-convex skeleton plate in multiple directions to a square, a circle, etc. for packaging, machine manufacturing, construction, etc. A composite structural system in many fields.

Background Art ^

At present, known materials are fused into plates, blocks, squares, circles, etc., and their internal structure is single. Reinforcement (or other materials) is used to make bone cages, and then cement mortar is used to prefabricate concrete components. The production of reinforced bone cages is mostly done by hand, with low mechanization, long construction period, low efficiency, and severely affected by site weather. Cannot form factory production. Because the concrete structure is primitive, the contact area between the reinforcing steel and the binder and the mixed material is small, and the degree of standardization is low. Often, the strength of the concrete member is low due to the low density of the reinforced bone cage, and the quality is too heavy. It is easy to melt the steel in high temperature Causes overall collapse. With the known technology, it is difficult and difficult to process the thin concrete plate below 10mm, and it is almost impossible to realize it below 3mm. .

Therefore, the known technology is used to manufacture concrete slabs with a small range of use (only for construction). At present, there is no standardization, high factory production efficiency and low cost. It can not only process large specifications and polymorphic components, but also produce ultra-thin sheet materials. It can be used in construction, packaging, machine manufacturing, etc ... Field rugged skeleton plate type coagulation composite structure.

In addition, at present, there are two types of composite structural paper used in packaging, one is corrugated cardboard, and the other is honeycomb cardboard. Corrugated cardboard is a strip-shaped structure, and its strength distribution is unidirectional, so it is easy to fold and deform along the strip. After lamination, the paper has a rough appearance and obvious stripe marks, which cannot meet the requirements of high strength and multiple orientations. For honeycomb paperboard, the core paper mimics the honeycomb structure too much, and the paper strips are bonded into a hexagonal mesh, cutting paper strips, viscose, stretching ... The process is complicated, the processing is very difficult, and the equipment investment is huge. At present, only cardboard with a thickness of more than 8 mm can be made, but in theory, only a thickness of about 3 mm can meet various packaging needs. Summary of the invention

The object of the present invention is to provide a concavo-convex slab-type coagulation composite structure with reasonable design and simple structure, which can both process and produce large-sized polymorphic components and can also be used for secondary processing (molding) of ultra-thin sheet materials.

Another object of the present invention is to provide a reasonable design, simple structure, and strength analysis. Concave and convex skeleton plate type composite structure with uniform cloth, small distortion and easy production.

The object of the invention is achieved in the following way:

The concave-convex skeleton plate type coagulation composite structure includes a concave-convex skeleton plate, a coagulation slurry, and upper and lower surface layers. The concave-convex skeleton plate is first processed into rows and rows of pits and protrusions on the surface of a metal or non-metal plate. The protrusions are staggered to form the middle concave-convex skeleton plate of the coagulation composite structure, and then the pre-processed coagulation slurry (made by mixing the binder and the mixed material) is bonded to the upper and lower surface spaces of the concave-convex skeleton plate. After compounding the surface layer of other materials, it will become an uneven skeleton plate type coagulation composite plate after solidification. In addition, before solidification, a small amount of steel bars can be connected between the multiple layers of the concave-convex skeleton plate and / or through adhesive bonding. Furthermore, when the concave-convex skeleton plate-type concrete composite structure is to be extended outward in the plane direction to form a larger one When the area of the concave-convex skeleton plate and the concave-convex structure of another concave-convex skeleton plate are overlapped and wedged with each other, the concave-convex skeleton-plate coagulation composite structure capable of bending and changing directions can be made. The concave-convex skeleton plate may be bent. By superposing, wedging, and bending the concave-convex skeleton plate, the concrete composite structure of the concave-convex skeleton plate can be extended in multiple directions, and multi-size concrete composite plates and square, circular, and other polymorphic components can be processed.

A concave-convex skeleton plate type composite structure includes a concave-convex skeleton plate and an upper and lower surface layer, and the concave-convex skeleton plate is processed with a concave-convex structure in a row. Top and bottom bumps.

The concave-convex skeletal plate-type composite structure may further include reinforcing steel, which is passed through the concave-convex skeletal plate and the upper and lower surface layers.

The concave-convex skeleton plate is also a double-sided concave-convex skeleton plate processed as described above, that is, a row of pits and a row of protrusions on the surface of the plate. The convexity on this surface is the concave on the back, and the concave on this surface is It is a bump on the back, suitable for forming thick gauge composite boards and components;

Alternatively, the concave-convex skeleton plate is a processed single-sided concave-convex skeleton plate, that is, one side of the plate is a depression, and a corresponding portion on the other side opposite to the depression is a protrusion, which is suitable for processing an ultra-thin composite plate. .

The concave-convex skeletal plate composite structure may also include multiple layers of the concave-convex skeletal plate, and the multilayer concave-convex skeletal plates are connected by the reinforcing bars and / or connected by bonding.

The concave-convex structures on the edges of adjacent concave-convex skeletal plates overlap each other and / or bend, so that the concave-convex plate-type coagulation composite structure extends in multiple directions.

There is also a concave-convex skeleton plate type composite structure, which includes the concave-convex skeleton plate and one of the upper and lower surface layers, the concave-convex skeleton plate is a core paper, and a surface of one side is concave. The rollers and convex rollers are heated and pressed to form a row and a row of pits. The other side of the core paper forms a row and a row of protrusions at corresponding positions.
