ENERGY STORAGE RACK

An energy storage rack includes a vertical column (10) and a horizontal beam (20). The vertical column (10) is formed by a first beam (11) and a second beam (12) butting against each other. The first beam (11) includes a first main body (111) and first connecting plates (112), and the first main body (111) has a first groove (113). The second beam (12) includes a second main body (121) and second connecting plates (122), and the second main body (121) has a second groove (123). The two second connecting plates (122) are correspondingly connected to the two first connecting plates (112), and the first groove (113) communicates with the second groove (123) to form a hollow cavity. The first beam (11) is fixedly connected to the second beam (12) through the first connecting plates (112) and the second connecting plates (122).
