Hardwood is a kind of board made of wood processing waste, which is processed into wood chips of certain specifications, and then hot pressed with adhesives. Hardwood has large breadth, flat surface, good heat insulation and sound insulation performance, consistent longitudinal and transverse strength, convenient processing, and various veneers and decorations can be carried out on the surface. Hardwood is an ideal material for making panel furniture models. Due to its fine and flat cross section, it is easy to cut and plane the flat and flat unidirectional curved surface after the plates are overlapped and glued.
The cork board is easy to process, non-toxic, noiseless and fast to make. The model made with it has its special texture. When the thickness of the cork board is not enough, the cork board can be stacked and glued to achieve the required thickness. When processing, the single layer can be used with a scalpel or a paper cutter, and the multi-layer or thick layer can be used with a bench curve saw and a manual wire saw. Attention should be paid to its structure when using the cork. If the particles of the cork are too coarse, it will hinder its use. The cork used in scientific and technological practice or the cork used in medicine are particularly suitable for making models.
6 protection measures for building formwork:
(1) Storage
When we store the templates, if there are two templates, we should store the plates face to face. If the formwork is stored on the construction floor, solid anti dumping measures shall be taken to store the formwork vertically on the outer wall. Other unsupported formworks shall be stored on a special stacking rack, but do not lean against other formworks or other items to prevent slipping and dumping.
(2) . haulage
The general transportation mode of building formwork is to use the trailer for overall haulage, and the trailer can be used for horizontal stacking and haulage after removal. However, the skid should be aligned up and down and firmly placed. People cannot sit on the vehicle during haulage.
(3) Hoisting
Before lifting the formwork, check whether the ropes, fixtures and lifting rings on the formwork are complete. Remove other temporary supports before lifting. Before lifting the formwork, the position of the crane shall be adjusted. Workers shall not carry the formwork to prevent the formwork from swinging greatly or bumping other formwork.
(4) . disassembly and assembly
When the formwork is disassembled, the surrounding area shall be fenced and hung with signs. Non staff are strictly prohibited to enter. The personnel commanding, removing and hooking shall stand in a safe place to command the operation, and the construction personnel shall not lift with the formwork.
(5) Auxiliary facilities
The formwork shall be equipped with safety facilities such as upper and lower stairways and protective railings. In case of damage, it shall be repaired in time. This ensures the construction safety of workers.
(6) . protective measures
After the formwork is installed, measures against electric shock shall be taken, and special personnel shall be arranged to connect the formwork in series and then connected with the lightning protection network to prevent accidental leakage.
After the formwork is removed, the residual dirt on the formwork shall be removed in time, and then a layer of stripping agent shall be applied. When the dirt on the formwork is removed and the stripping agent is applied, the formwork shall be temporarily fixed, and a 50-60cm wide sidewalk shall be reserved between the formwork with the plate surface relatively parked.
