First, timber to reduce the deformation principle:

Are the natural growth of timber materials, because of the growth rings, materials such as differences in the internal organizational structure, to do no deformation is impossible. Two methods are usually a combination of methods to reduce the deformation of wood: one is to use advanced drying degreasing equipment for timber drying degreasing, wet wood can be used to dry wood, the timber containing less internal stress. The other is the expected long short finger jointing material (ie, vertical integration, to reduce internal stress unloading deformation), wide material with a narrow bonding material (ie, horizontal integration, with shortening of the root is expected to reduce the deformation of the ring). That is why in their daily lives, longitudinal and transverse (two-dimensional) to replace the substantial timber specification of the real cause of solid wood material.

Wood is a "sponge body," "wet-up shrinkage" is the other property. The wood structure of the asymmetry decide the timber to wet up the shrinkage rate is not the same. Substantial scientific experiments show that the vast majority of wood, tangential (circumferential direction) wet up are radial shrinkage rate (diameter direction) of the double are vertical (the direction of tree growth) relations between the two times, while the tensile strength It is precisely the contrary, the longitudinal tensile strength of wood is string, two times the radial relationship. This is criss-crossing such as plywood boards with sticky wet due to horizontal shrinkage rate rose more than tenfold reduction in tensile strength has increased more than tenfold and extensive solid wood panels to replace the real reason.

Clearly, the longitudinal and transverse (two-dimensional) to replace the large-scale timber Fangde expected to solve the deformation problem, but still can not solve the transverse shrinkage of wetlands up too much problem. If the vertical and horizontal (two-dimensional) basis of timber and then glue on the second floor of a horizontal board, will resolve the deformation problem, and solved the problem of horizontal shrinkage wet up, because of the horizontal tensile strength increased ten times, in fact, also solve the problem of transverse cracking and reduce the lateral deformation. We put such a timber, called the vertical and horizontal three-dimensional timber.

Interior decoration materials of wood to shape the performance of solid wood materials has been the most luxurious and have vitality. Venetian series of solid wood products, such as, doors, windows and so on, are based on longitudinal and transverse three-dimensional timber (or two-dimensional longitudinal and transverse timber) as the substrate, using the song pressure (pressure level) hot technology, processing formed. On the one hand, it has a solid wood features luxurious and there is significant productivity; On the other hand, less than timber Products deformation, cracking and wet up the low rate of shrinkage, which is solid wood Venetian Series basic features.

We must affirm that the longitudinal and transverse two, three-dimensional timber, the timber can greatly reduce the deformation, cracking and shrinkage of wetlands up problem, but it is impossible completely to solve the deformation, cracking and shrinkage of wetlands up questions; we are talking about does not deformation, deformation degree refers to the country or enterprise does not exceed the standard scope of permit; we are talking about not cracking refers to cracks are not structural, rather than minor skin cracks and crannies.

Two, what mortise technology

Mortise are commonly used in our traditional building skills, are the crystallization of the wisdom of our ancestors. At the ancient temple architecture, or often can be found. Used properly can combine the whole structure was very solid, without one nail one needle. Wooden bench in general can also be found in such skills.

Mortise are two pieces of material to make a, a mortise to make, both to wear to work together and rely on the friction material will be fixed with two pieces of material.
