Reinforced cultural relics rack shelf
Technical field:
This utility model relates to bracing frame technical field, particularly relates to a kind of for the shelf of placing articles in cultural relics rack and reinforced cultural relics rack shelf.
Background technology:
Compact shelving, also known as intensive Light Duty Rack, applies to office, enterprises and institutions' Reference Room, archive office, sample room, and books and reference materials, archives, kinds of goods, archives financial affairs receipt, historical relic are deposited by museum etc., the novel harness of goods; Compared with traditional bookshelf, shelf and document shelf, have that storage capacity is big, joint space-efficient feature. And cultural relics rack is as a kind of type of compact shelving, its cultural relics rack is usually made up of support body and the shelf being arranged on support body, the shelf of existing cultural relics rack is formed by one piece of sheet metal forming, shelf is single flat plank frame generally, make shelf bulk strength poor, and historical relic is as comparatively expensive heavy articles, particularly when shelf is longer, the bending resistance of shelf tends not to meet the requirement that a large amount of historical relic is deposited, and it is likely to result in the damage that must do not want to historical relic and loss.
Utility model content:
The purpose of this utility model seeks to provide a kind of reinforced cultural relics rack shelf, and it to solve the problems referred to above existing for existing cultural relics rack shelf, it is provided that a kind of assembling is simple, and bending resistance is strong, and bearing capacity is big, multiduty reinforced cultural relics rack shelf.
The utility model discloses a kind of reinforced cultural relics rack shelf, including shelf main body and reinforcement cover plate, its described shelf main body is movably arranged to be strengthened in the cavity that cover plate is defined.
Two sides of described shelf main body are along having step groove.
Improving further, described reinforcement cover plate dual-side is along being bent inwardly to U-shaped flange.
As preferably, described reinforcement cover plate dual-side is along being bent inwardly to C type flange.
Compared with prior art, the utility model has the advantage of: cultural relics rack shelf is assembled by shelf main body and reinforcement cover plate, the dual-side of shelf main body has step groove, can strengthening free pull in the defined cavity of cover plate, easy for installation, and the dual-side edge strengthening cover plate is bent inwardly to U or C type flange, the side strengthening cover plate is made to have the structure of reinforcement, utilize the flange that these are set up, improve the intensity of shelf, such that it is able to omit the crossbeam arranged on the shelf, when strengthening cover plate bottom surface and upwards placing, moreover it is possible to dust-proof; Therefore, this utility model is easy for installation, and bending resistance is strong, and bearing capacity is big, multipurpose.

Detailed description of the invention:
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Such as Fig. 1-Fig. 3, specific embodiment for utility model, this cultural relics rack shelf includes square shelf main body 1 and strengthens cover plate 2, shelf main body 1 both sides are provided with step groove, strengthen the dual-side of cover plate 2 along being bent inwardly to U-shaped flange, shelf main body 1 is inserted and is strengthened in the cavity that cover plate 2 bending is defined, and the step groove of shelf main body 1 both sides is chimeric with the U-shaped flange strengthening cover plate 2 both sides. In this utility model, shelf main body 1 can freely assemble with strengthening cover plate 2, easy for installation, the both sides strengthening cover plate are bent into U-shaped flange, improve mechanical strength and the rigidity of structure of cultural relics rack shelf, thus significantly improving the operation stability of intensive cultural relics rack shelf, reliability and safety, and according to placing the needs of object, the bottom surface of optional shelf main body 1 is upwards placed, also the optional bottom surface strengthening cover plate is upwards placed, and purposes is many. Compact shelving shelf described in the utility model solves placing articles, and when frame shelf is long, the problem of intensity difference and bending resistance difference, service life is greatly improved.
The dual-side strengthening cover plate can also be bent to form the flange of C type by this utility model, and as shown in Figure 4, this C type flange can be the flange of arc transition, and this C type flange can also be the flange formed by three end to end flangings, graph structure as shown in Figure 5.
