Description

Stacking corrugated annular stretching furniture structure

Technical Field

The invention mainly relates to a technology of composite corrugated stacked curved-surface plates, in particular to a multi-layer stacked corrugated annular stretching structure.

Background

The application scenes of portable temporary emergency furniture are more and more extensive, and for example, middle and short-term renters face the difficulties that self-purchased furniture is difficult to move away and resale, and the like. The price difference of the furniture of the same category is large due to the differences of raw materials, design level, process flow and the like. Portable, interim collapsible paper base furniture of emergent formula has that the transport is convenient, weight is lighter, the volume is less, easily retrieve and recycle, has characteristics such as multi-functional, easy installation, modularization, nimble changeable, satisfies the user's demand of emergency, show exhibition, short-term rent room of hiring after the calamity, and its common form is inflatable, detachable, foldable. However, the existing portable and temporary emergency paper-based furniture products generally have some defects, or the honeycomb structure with large holes and large walls is adopted, so that the bearing capacity is insufficient, and the honeycomb structure is crushed and the products are damaged; or the product is directly stacked by adopting the micro-porous small-wall corrugated board, which can meet the bearing requirement of the furniture products in medium and short periods, but the product is heavy and difficult to transport, and the advantages of the paper-based light furniture are lost. Therefore, the development of paper furniture with light weight, high strength, portability, safety and environmental protection is an objective requirement for high-quality development of the home industry in the new era.

Disclosure of Invention

In order to solve the defects of the prior art, the invention provides the stretchable and bendable stacked corrugated structure furniture which is light in structure, easy to bend, annular in stretching, reliable in strength and capable of ensuring the visual effect of appearance, and also provides a multilayer stacked corrugated annular forming process. By means of the plasticity of the raw materials, a special stacked corrugated structure is adopted, and a cellular structure is formed by bonding, so that the super-strong bearing capacity and the stretching ratio are obtained.

The scheme is realized as follows:

the multilayer stacked corrugated annular stretching structure is formed by annularly spreading n corrugated units along a facing film, covering a panel and fixing the covering film. A flat base band is glued with the convex edge of a corrugated base band to form a hollow corrugated unit. A plurality of corrugated units are sequentially and vertically stacked together to form a large-width corrugated board, adjacent corrugated units are not bonded, and auxiliary boards are respectively bonded on the two outer side plane base tapes of the stacked corrugations. And adhering a covering film to only one side surface, wherein the length of the covering film reaches the auxiliary board. Stretching and unfolding the film into a fan shape along the annular shape of the facing film, wherein the facing film is a fan-shaped inner arc surface. And covering a panel on the stretched annular corrugation, wherein the area of the panel is larger than that of the cross section of the stretched stacked corrugation. The connecting strips are attached to the auxiliary plates, and the connecting strip fixing auxiliary plates are respectively attached to the auxiliary plates on the two sides. The corrugated unit comprises n +1 flat base belts and n corrugated base belts, and the flat base belts and the corrugated base belts are uniformly stacked and arranged. The corrugated units can be single corrugated units, multi-corrugated units or two types of composite stacking. The n corrugated units are radial and vertical to the ground, play a supporting role on the panel, and have a hollow structure in the middle.

As a further improvement to the above technical solution:

the corrugated unit can be made of paper, thin metal, plastic and the like, the corrugated shape can be U-shaped, V-shaped and UV-shaped, and the sizes can be A-shaped, B-shaped, C-shaped, D-shaped and E-shaped, and the combination of the types. The covering film can be paper, plastic, veneer, metal, glue film, etc., and has a thickness of 0.1-1.5mm. The auxiliary board can be made of cardboard, plastic, wood board, metal, etc., and has a thickness of 2-8mm. The panel can be made of cardboard, plastic, wood board, metal, etc., and has a thickness of 2-10mm, and the shape of the panel can be round, oval, polygonal, etc. The connecting strip can be a magnet strip, a magic tape and the like.

The corrugated stack ring-shaped expansion can be circular closed, semicircular and arc-shaped stretching and stretching, and the panel splicing structure plays a role in supporting and buckling the auxiliary plate.

Compared with the prior art, the technology has the advantages that:

through setting for the annular expansion of the stacked corrugations, the corrugated units are mutually supported, so that the structure has ultrahigh strength-to-weight ratio and can be suitable for occasions such as portable, temporary display and emergency furniture. Moreover, the technology solves the defect that the corrugated sandwich structure can only be used for shaping straight products. In addition, the corrugated units are annularly arranged side by side in a circle and mutually supported to form a triangular structure body, so that the corrugated units have better bearing strength and can be directly used after being unfolded. The technology simultaneously solves the bearing of the paper-based corrugated structure, does not need to be additionally fixed by hardware, and has simple process, easy industrialization and low-cost production.
