Construction technology of Bijie anticorrosion wood trestle
Material preparation: processing and making wood parts, wooden parts assembly and wood decoration
(1) preparation of wood material: the variety, material, specification and quantity of wood must be in accordance with the requirements of the construction drawings. Board, wooden material is not allowed to have decayed, moth phenomenon, there are cracks in the connection of the shear surface is not allowed, a discomfort is too concentrated, and not allowed to live a. Log or wood moisture content should not be greater than 25%, water wood structure rate should not be greater than 18%. The anticorrosion, insect proof and fire prevention treatment should be constructed according to the design requirements.
(2) wood processing production: all kinds of wooden construction according to the construction drawing requirements of material processing, according to the different machining precision for the machining allowance。 The processed wood fabric will check the specifications and quantity in time, and the pieces are stacked neatly。 The hard wood deformation, piled up to take appropriate measures to prevent deformation。
(3) the assembly of wooden parts:
The quality of A. structural components must conform to the design requirements, without damage or deformation during stacking or transportation.
The support, support and connection of the wood structure of B。 must conform to the requirements of the design and construction specification, and the connection must be firm and no loose。
The support parts of the C。 roof, beam and column should be treated as anticorrosive treatment according to the design requirements or construction specifications。
D. platform, wooden Zhanqiao, wood bonsai and other garden items should be treated as anticorrosive treatment according to the design requirements or construction specifications. The connector shall be made of stainless steel or galvanized iron.
(4) wood structure finishing:
A. remove burrs, wood surface dirt, polished with emery cloth.
B. bottom putty, dry polished cloth.
C。 is designed to require primer, topcoat and layer by layer。
D。 color mixing paint brush, anti leakage, no blistering rust, through the end, sagging, wrinkled skin。
E。 varnish brush, no blistering, leakage spot, through the end, sagging, wrinkled skin, the surface is bright and smooth, straight lines。
The application of clean cloth F. tung oil immersion oil after squeezing, rubbing on dry wood surface. No leakage of coating, peeling, wrinkle, stain, flow through the end, smooth surface, smooth, straight lines.
G. wooden platform hot wax, soft wax cleaning engineering, the use of wax varieties, quality must meet the design requirements, is strictly prohibited in the construction process of Tanghuai floor and surface damage
The above is the Bijie mill house stack Wooden Structure Construction anticorrosion technology;
