The composition of high shelf is generally column and beam as the main parts, which greatly improves the storage capacity per unit area of the warehouse and gradually becomes the mainstream shelf type in the market. The warehouse in use abroad is as high as 30 meters, and the warehouse in use in China is almost 20 meters in height. .
With the increasing requirements for the storage rate of warehouse goods, storage shelves have entered most warehouses and workshops, covering large and small warehouses in all walks of life.
Simple storage racks can be installed by manufacturers by themselves with installation drawings. For more difficult storage racks or with a little technical requirement, professional installers can install them. The cost of buying simple storage racks can save a lot, but what type is simple Storage shelves?
Heavy duty racks, loft racks, through-type racks, shuttle racks, etc. are all types of racks with a relatively large area and high installation accuracy requirements. Professionals must guide the installation on site, while medium-sized racks and light-duty racks are relatively simple in structure , The shelf type that is convenient and quick to install, you can install it yourself, and you will learn it. But there are some things to pay attention to when installing.
1. The straightness of the storage rack, that is, the length direction, the depth direction and the height direction, must be straight and right-angled, so that it can be installed during installation and there will be no problems in operation. This is also the basic precautions for the installation of warehouse racks.
2. Stability. In addition to fixing the bottom of the column, you also need to fix the top. Because the height of the shelf is higher, the columns will definitely be offset after standing, so they should be fixed by top pulling between rows. To ensure the stability of the shelf and the accuracy of the channel size.
3. After fixing the remaining columns, erect the entire shelf and place it on a flat ground. Shake the shelf quietly to see if the shelf is stable. After confirming that there is no problem, use a specific screwdriver to reinforce all screws. Afterwards, put the installed rack on the place where it will be used.
The high rack beam adopts C-shaped steel welding beam, which is similar to the production method of the column. The thickness of the material is usually 1.5mm, sometimes 1.8mm, the width is 90-140mm, and the height is 50mm. There is also a type of beam called P beam, which is commonly used in the type of shelf for storing light small items such as medium-B shelf. The load-bearing requirement is not very large, and the load-bearing capacity of each layer is less than 1000kg.
The column of the high shelf is made of Q235B strip steel, rolled by an automatic rolling mill, punched by a punch, and cut according to the design height. The commonly used thickness of strip steel is 1.5mm and 2.0mm, and the column specifications are 90*65*, 130*65, 55*45, etc., which need to be determined according to the bearing capacity of each layer and the overall bearing capacity. The thicker the material, the larger the specification. The unit price will increase accordingly.
Special attention: Do not tighten the screws too tightly before the shelf is installed. After installation, make sure that the shape of the shelf is normal. Reinforce the screws after there are no other problems.
