The moisture content of the wood should be determined at the sampling site or in the same area. The test part takes the position of the specimen above 100mm from the ground, selects three parts in different positions, and on each part, measures once at each point of the optional Miga Bridge, and obtains the average value measured on the three parts respectively, and the largest average value is the wood moisture content of the specimen.

FlatnessFlatness refers to the degree of local flatness of the surface of the product (component) within the range of 0 150mm. Adjacent perpendicularity refers to the degree of irregularity when the shape of the product (component) is rectangular.
Position difference refers to the distance between two adjacent surfaces of the door and the frame, the door and the door, the door and the drawer, the drawer and the frame, and the drawer and the drawer in the product. AppearanceAppearance refers to the exterior of the product where it is finished or otherwise treated. The inner surface refers to the finishing or other surface treatment in the glass door or other spaces (such as shelves, etc.) of the product.
Interior interior refers to the visible surface inside the door or drawer of the product. Concealment Concealment refers to the place inside and outside the product that is not easy to see in general use.
4 Technical requirements Main dimensions and dimensional tolerances The main dimensions of tables, chairs and stools should comply with the provisions of GB 3326. The main dimensions of the cabinet should comply with the provisions of GB 3327. The main dimensions of the bed should comply with the provisions of GB 3328.
The limit deviation of the width, depth and height of the product is 5mm, and the limit deviation of the supporting or combined products should be positive or negative.

Anonymous users2024-02-02The construction unit of the timber structure project (including the laminated timber processing plant) shall have the corresponding qualifications and construction technical standards (or manufacturing process standards), a sound quality management system, a quality inspection system and an evaluation system for the comprehensive quality level.
The quality management of the construction site can be checked and recorded in accordance with the requirements of Appendix A of the Unified Standard for Acceptance of Construction Quality of Construction Projects GB50300-2001.
The timber sub-division works are composed of square timber and log structures, glulam structures and light timber structures and the protection of timber structures, and can only pass the acceptance when the sub-projects are accepted.
The sub-project shall be accepted after the inspection batch is accepted.
The inspection batch should be divided according to the type of structure, the stress characteristics of the components, the type of connectors, the shape and size of the cross-section, the tree species used and the amount of processing.
The construction quality of timber structure engineering shall be controlled according to the following provisions:
1.Timber (including specification timber and wood-based structural panels), steel components and connectors, adhesives and laminated timber components, appliances and equipment used in timber structure engineering shall be subject to on-site acceptance. All materials or products involving safety and function shall be re-inspected in accordance with the provisions of this specification or the corresponding professional engineering quality acceptance specifications, and shall be inspected and approved by the supervising engineer (technical person in charge of the construction unit).
2.Each process should be controlled according to the construction technical standards, and after each process is completed, it should be inspected.
3.The handover inspection should be carried out between the relevant professional types of work, and a record should be formed. Without the inspection and approval of the supervising engineer (the technical person in charge of the construction unit), the construction of the next process shall not be carried out.
