Storage rack: with the increase of connection coefficient, the load-carrying capacity of the beam is enhanced, but the stability is weakened (i.e., it is easy to lose stability); the connection coefficient is 0.3, which is the best bearing state of the crossbeam.
The connection between the cross beam and the column in the combined shelf adopts a special plug-in connection mode, the cross beam is embedded into the hole of the column by hanging pieces. This connection mode not only allows the beam to rotate, but also requires that the end of the cross beam can transfer part of the load of the cross beam to the moment action of the column. Simplifying this semi-rigid connection as a simple rigid connection or ideal articulation is not in line with the actual situation.
To calculate the price of heavy shelves, the first choice is the rack。 We need to understand the structure of heavy duty shelves。 Generally speaking, heavy duty shelves are mainly composed of shelves, columns, beams and pins。
Column sheet: It consists of two columns + cross brace + diagonal brace。
Crossbeam: The moment tube beam, embracing welded beam or P-shaped beam are selected mainly according to the load-bearing capacity.
Attachments: foot guards, fences, braces, grilles, rear gears and protective nets, etc. Attachments are customized according to customer needs and site requirements.
A shelf type that can effectively improve the utilization rate of warehouses is characterized by: it is a warehouse which can not be divided by channels, continuous overall shelves, and the utilization rate of rack shelves can reach 50%, which is suitable for warehouses with few varieties, large quantities and low first in first out requirements. The rate of selection is 20%-30%.http:// www.cgkcw.com.
