Student desks are an indispensable piece of furniture for schools and other educational institutions. The desks are a platform for students to learn. Therefore, there are relevant regulations on the size and materials of the desks. This is to ensure that students have better learning. Experience.
The history of student desks begins with the octagonal desks of the earliest schools. Schools and school desks are collectively called desks. In recent years, based on anthropometric data and special surveys, China has promulgated the Standard for Functional Sizes of School Desks (GBT-3976-2002). There are ten height standards for tables and chairs used by students of different heights, ranging from 1 to 10. For example, the height of table 1 is 76 cm, the gap of table 1 is H1 is greater than or equal to 63 cm, the gap of table H2 is greater than 49 cm, etc. It is suitable for students above 1.73 meters, and table 2 is suitable for students from 1.65-1.79 meters in height, high school students. Select at least two models. The range of 1-4. According to regulations, the form of school desks and chairs can be chosen at will, but the main dimensions such as the height of the table, the height of the space under the table, and the height of the chair surface must conform to national standards.
According to the classification of desk materials, there are currently three main products on the market: wooden desks (student desks and chairs of miscellaneous wood and solid wood processing, often used in non-urban areas); steel-plastic desks (combination of steel and plastic as product support, and Use NG melamine board as the panel; rubber-plastic table (rubber-plastic alloy material). According to the use of desks and chairs, flat tables are usually used in primary and secondary schools, and universities have ladder tables, reading room tables, etc. Of course, the desks of primary and secondary schools It is also divided into adjustable tables and fixed tables. The desks and chairs of our students generally follow the development track of western school desks and chairs.
The main material of the student desk frame is high-quality steel pipe with a wall thickness of more than 1.2mm, and the steel pipe of the main support frame has a wall thickness of more than 1.5mm. Steel pipes are welded with high frequency welded pipes, with good mechanical properties and smooth surfaces. The hopper adopts a shaped stamping barrel, which is smooth and seamless, and has good safety performance. The desktop board adopts 18mm fireproof veneer. After molding, the fireproof board has abrasion resistance, heat resistance, acid and alkali resistance, smoke resistance, impact resistance and other properties. The back and seat panels are made of multiple layers of thin wood folding panels, and the surface is covered with a heat-pressed fire-resistant panel. Its characteristics are good bonding performance, high strength, good durability, smooth surface, realistic texture, bright colors, and thickness of 12 to 14mm. It can also be used for one-shot PVC and hollow plastic chairs. The electrostatic spraying on the surface of steel pipes has the characteristics of strong adhesion, good gloss, hard plastic powder, wear resistance, impact resistance, water resistance, light resistance, light retention, color retention, etc. The sprayed surface is smooth, smooth and bright in color.
Student desks occupy an important position in students' daily learning, and daily work cannot be separated from it. The utilization rate is also relatively high, so the tables and chairs used by students should be more in line with the human-machine size. This will not only cultivate good sitting habits, but also improve work efficiency and reduce the occurrence of occupational diseases. Student tables and chairs are representative of furniture.
