Speaking of student bookshelf is no stranger to many people. During the student period, many people need to read a large number of books to enrich their own knowledge, and the placement of books has become a big problem. Since having a student bookshelf, this trouble can be easily solved. The following small series takes you to understand the classification of student bookshelves. Classification of student bookshelf: 1. Single column type. The so-called single-column bookshelf refers to the weight of the books on each side of the single-column metal plaque on each side, each shelf is 90cm in length, and can be used separately or continuously. Generally speaking, the height of the bookshelf is more than 200cm, and the top will be coherently tied for safety. 2. Complex column type. It refers to the two sides of the bookshelf, each with more than two pillars, bearing the horizontal partition to transfer the book load. However, in order to promote the appearance, wooden boards are attached to both sides and tops of the metal-made column type bookshelf. For example, a stacked bookshelf. In order to make full use of the limited collection of books in the limited space, it is a good method to use the solid and durable characteristics of steel materials to provide display books for laminated bookshelves. However, each country has its own specifications for bookshelves. For example, the stacked bookshelves in the United States are 2280mm in height and each layer is divided into 5~7 segments. In European countries such as the United Kingdom, the net height of each floor is 2250mm. The width of the partition is 200mm on one side and the width of the support is 50mm. 3. Sliding type. The slide-type dense bookshelf can be divided into manual and electric forms. The two special fixed, the middle bookshelf borrows the base rails and guides the sliding, which is one of the methods for effectively utilizing a large number of books in limited space. For example, wooden bookshelf materials, including solid wood, fascia board, wooden core board, granule board, etc., are formed by processing, coating with paint or using surface decoration materials, and have a soft texture. The commonly used form of the library is the upright type, and the tilting type L-shaped bookshelf is convenient for the reader to access the books and has different types of specifications. 4. Dense bookshelves. The main and obvious feature of dense bookshelves is the saving of book space. It puts the front and back bookshelves tightly together, and then uses the track to move the bookshelves, saving the space around the bookshelves before and after the bookshelves, so that more books can be placed in a limited space. Because of the closeness of the bookshelf, it also makes it a place to properly protect books; in addition, it also increases the ease of use and care. But dense bookshelves also have some drawbacks. The first is that the cost is too high, and unless there is a generous budget, it is not easy to fully equip the facilities of the dense bookshelf (such as the plaque and control facilities). This is followed by the security of the bookshelf, which includes security concerns for general use and earthquakes. Due to technical improvements, the dense bookshelf has been changed from the earlier mechanical type to the electric operation, and the user only has to follow the steps to operate the safety is very high. However, the safety of the dense bookshelves during the earthquake (the book is also for people) is always difficult to master. When the earthquake strikes, they are still vulnerable. 5. Tree-shaped bookshelf. The Venetian designer kostas syrtariotis exhibited his latest product "Tree Bookshelf" at the kidsroomzoom event at Milan Design Week 2011. Known as the name of the tree, this shelf is stretched out on the wall, and the user can place a book or other small object on the branch. The designer chose ebony and eucalyptus wood as the material for the production, and the surface was coated with a layer of polished paint. The “tree-shaped bookshelf†can be assembled in less than 10 minutes. It can be placed against the wall and can be fixed with only two screws.
