Structural reinforcement of high beam racks
In the high beam type rack, in order to increase the structural stability of the rack, there will be many auxiliary components and methods in the installation. The more commonly used ones are fixed by expansion bolts on the ground, back-to-back racks are connected by spacers, and the racks on both sides of the forklift aisle are used. Channel tie rods for connection and so on. In particular, the channel tie rod connection can effectively connect all the beam-type shelves of the warehouse into one body, which greatly increases the overall stability of the shelves in the warehouse, so it is widely used in beam shelves.
In some special cases, the racks on both sides of the forklift aisle have different lengths and different types of racks, resulting in misalignment of the positions of the pillars on both sides of the aisle. At this time, it is not very convenient to install the aisle tie rods. In these cases, if the shelves are back-to-back, they can be reinforced by spacer connections; if the shelf height is low, the stability of the shelf itself is also guaranteed; or there are single-row shelves with a higher height, which can also be used if the wall is shocked. The connecting rods are fixed to the wall. But if there are single-row, high-height beam shelves that are not against the wall (or inconvenient to be fixed to the wall), how to strengthen the stability of the shelves?
Recently, we encountered a similar cold storage beam rack installation: single-row racks are 8 meters high and cannot be installed with aisle rods. They are against the wall but the wall is a cold storage insulation wall, which cannot be reinforced by connecting rods, expansion bolts, etc. to the wall. Drawing lessons from the shelf reinforcement method of the through-shelf, we installed a number of diagonal pulls on the back of the shelf to tighten the shelf in actual installation, and then fixed a number of angle steel fixings on the ground, and then fixed it with the shelf through diagonal pull. By pulling the shelf tightly as shown in the figure and fixing it to the ground, the structural stability of the shelf can be increased to a certain extent.
