Glued wood structure form

This kind of glued wood mainly has two structural forms, one is laminated glue and structure, which is composed of small squares or some wooden boards piled into rectangles or other shapes, and then combined with members of other sections. Its advantage is that it can learn from each other's strong points to make small or short wood more widely used and improve the utilization rate of wood.

There is also a plywood structure, that is, ordinary wood or plywood is used, and then I-shaped or turned into wallboard, pipeline structure and so on. The advantage is that it has strong adaptability and can be used as a load-bearing structure to meet the construction needs.

Basic classification of glued wood structures:

1. Laminated bonding structure

Rectangular, I-shaped or other cross-sectional members and their structures are composed of wooden boards or small squares laminated with glue. The advantage of laminated board gluing is not only that small materials can be used for a long time, but also that different grades (or tree species) of wood can be placed in different stress parts, so that the number of wood can be used and the utilization rate of wood can be improved. However, in the case of a small amount of production, the price of this component is higher than that of ordinary wood, and only by mass production or large-scale use can good technical and economic effects be achieved.

Second, the plywood structure

Glued structure with plywood as panel and ordinary wood or glued wood as skeleton. According to the different stress state of plywood, it can be divided into two categories: one is the structure that mainly bears shear stress, such as I-shaped, box-shaped beams, arches, frames and pleats. The other is the structure that is mainly subjected to normal stress by plywood, such as roof panel, wallboard, shell and pipeline structure.

The advantage of plywood lies in its wide range and good homogeneity. Therefore, it has strong adaptability and can easily meet the requirements of architectural design when used as a load-bearing structure, but the quality requirements of structural plywood are higher than those of general decorative plywood, and specific quality standards are needed. The strength and durability of glued wood structures depend largely on the gluing quality. Design should be carried out according to special regulations. Therefore, in the design and manufacture, special technical requirements should be put forward for the selection of glue, the splicing structure of wood and the bonding process conditions.
