Description

Tenon-and-mortise spliced wood device and shelf bed

Technical Field

The application relates to the technical field of mahogany furniture production, in particular to a mortise and tenon spliced wood device and a frame bed.

Background

Now, as the economy of China is developed at a high speed and the income of people is continuously improved, the traditional rosewood furniture has irreplaceable characteristics and is popular with high-income people again; as the production process of the traditional redwood furniture (such as a shelf bed) has a large number of 'Chinese knot' type polygonal totem lucky sculpture pieces which are subjected to tenon-and-mortise joint assembly to form structural coamings and flower plate parts, and the traditional sculpture pieces are processed by using an independent wood plate integral double-sided transparent sculpture process.

In view of the inherent properties of wood: the longitudinal grain expansion and contraction rate is small, the breaking strength is high, the transverse grain expansion and contraction rate is high, the breaking strength is small, and the longitudinal and transverse expansion and contraction rates are nearly tens of times different (depending on the wood species). The complexity of the traditional process for manufacturing the shelf bed, the shelf bed must use rare wood (such as rare tree species such as pterocarpus santalinus, dalbergia odorifera and the like) with less difference of longitudinal and transverse expansion rates and high mechanical strength and stability, and the shelf bed needs to be manufactured by old and old materials; furthermore, the south area must be sealed by using multilayer painted raw lacquer, the north area is regularly sealed and maintained by wax, so as to ensure the stability of the mahogany furniture, and even if the maintenance of the mahogany furniture for a long time is improper, the phenomenon of deformation and cracking can still happen. Therefore, only the top grade of the redwood furniture made of the old materials, oil materials, single boards and other materials which are strictly adopted and even used for hundreds of thousands of years can be used by the honored persons and even the palace, so that a great amount of valuable wood can be rapidly consumed for producing the redwood furniture while the high-speed economic development is realized.

The traditional process needs to select high-stability and oily wood drying old materials (pterocarpus santalinus, pterocarpus tree species), then select and process relatively stable totem by straight-channel cutting plates, and splice a large lucky pattern board by tenon-and-mortise. However, the unique plate openwork carving process cannot solve the unique expansion and shrinkage characteristics of wood: the drying shrinkage, wetting and swelling of the wood are changed according to the difference of the section, the species, the water content and the like of the wood. Regarding the section of the wood, the xuan-directional shrinkage rate is about 6-10%, and the meridional direction shrinkage rate is about 3-5% (the longitudinal expansion and shrinkage rate is about 0.1% and can be basically ignored in the industry), the water content of the wood of the flower plate processed by the partial totem-tenon-and-mortise combined structure fluctuates due to the change of humidity in seasons, and the stress accumulated by the expansion and shrinkage rate causes the totem-tenon-and-mortise pattern to be wavy and skew (wet expansion), or the tenon opening cracks and even the carved piece cracks (dry shrinkage). If a 218CM by 200CM shelf bed cannot bear more than 1% expansion and contraction at all (the frames are wood longitudinal grains), it is equivalent to the whole openwork engraved plate needing to bear more than 2CM of wood expansion and contraction stress. The longitudinal grain strength of the wood of the integral opencut carving component is high, the longitudinal strength is weak, the longitudinal surface of the wood is easily affected by longitudinal stress, wet expansion, bending and drying shrinkage cracking are caused, the grain of the longitudinal cutting board is straight and monotonous (the deep cutting board needs to be used carefully, the drying shrinkage rate is doubled, the drying shrinkage stress is raised towards the circle center through the cutting board, and the wet expansion stress is bent towards the circle center), and the inherent natural defects of the wood cannot be changed even through strict painting, wax burning and other sealing processes.

Therefore, how to solve the problems of directional expansion and shrinkage deformation, low strength, high material selection requirement and monotonous texture of the device caused by the inconsistent longitudinal and transverse expansion and contraction ratios of the wet expansion and dry shrinkage of the wood in the existing single-plate openwork carving process is a key technical problem to be solved by the technical personnel in the field.
