Abstract
The utility model relates to a universal C-shaped steel sectional material with an inner folding bent edge. The universal C-shaped steel sectional material is structurally characterized in that one side of the steel sectional material is provided with a groove with a 45-degree edge, the bottom surface of the groove is provided with installing holes for cabinet combination, the other side of the steel sectional material is provided with two angle steel bending edges, modulus installing holes with modulus values being 20 or 25 hole pitches are formed in the two sides of the bent edge, modulus installing holes with the corresponding modulus values being 20 or 25 corresponding to the modulus installing holes formed in the angle steel bending edges are formed in the two sides of the sectional material, and a symmetrical inner bending edge is respectively arranged on the two angle steel bending edges. The universal C-shaped steel sectional material has the advantages that the relative dimension of the appearance dimension and the modulus value hole cabinet combining holes is unchanged, the original design is not influenced, and the universal C-shaped steel sectional material can be used after the corresponding sectional steel is replaced. The two inner folding edges are added, so the intensity of the sectional steel is enhanced, and the intensity of a machine cabinet is also improved after the combination. The cabinet combining holes are in hexagon shapes, special hexagon screw nuts are used as cabinet combining screw nuts, the operation is more convenient, the edge opening of exposed materials are inwards folded, and the potential danger of hand scratch injury during maintenance, installation, application and cabinet combination can be eliminated.
Description
Technical field
The utility model relates to a kind of rack steel profile for frame structure, specifically a kind of universal C shaped steel section bar with interior bending edges.It can be common to the control cabinet frame in different majors field widely, is specially adapted to the moving strong mesolow electric closet of stabilizing power of requirement in electric power system.The Design and manufacture field that belongs to device structure.
Background technique
Normally used a lot of by steel profile kind as cabinet frame, wherein the use in the field of business of C shaped steel section bar is commonplace.The general C shaped steel section bar (Fig. 1) using is due to simple in structure, it combines rear rigidity, intensity is all poor, form rack back loading limited in one's ability, electric closet in the electric power primary equipment particularly being used in a large number, because its moving stabilizing power is poor, rack intensity is also inadequate, so can not meet the requirement of the moving stabilizing power of high strength, although alteration of form several times, has increased the intensity of steel profile, in the link of some part, process still aobvious perfect not (Fig. 2) (ZL200920038736.2).As the limit mouth of interior flanging exposes, rack in column is arranged side by side, and cabinet is inconvenient, has left defect to the Perfect in shape and function of product.
Summary of the invention
The utility model proposes a kind of universal C shaped steel section bar with interior bending edges, its object is intended to overcome the existing above-mentioned defect of existing C shaped steel section bar, realizes the perfect of profile structure, makes its intensity better, connects cabinet convenient.
Technical solution of the present utility model: the universal C shaped steel section bar of bending edges in band, its structure is that the one side in steel profile is provided with the groove with 45 ° of limits, in the bottom surface of the groove on 45 ° of limits, be provided with and cabinet mounting hole, the another side of steel profile is provided with two angle steel curved edges, two sides in angle steel curved edges are provided with the modulus mounting hole that modulus value is 20 or 25 pitch-rows, and in steel profile two sides, being also provided with the modulus value corresponding with the modulus mounting hole of angle steel curved edges setting is 20 or 25 modulus mounting hole; In two described angle steel curved edges, be respectively provided with one symmetrical inner bending limit.
Advantage of the present utility model: change the C shaped steel after design, because boundary dimension and all modulus values do not become by Ji Binggui hole, hole relative size, do not affect original structure design, just can use as long as change corresponding shaped steel.But owing to increasing flanging in Liao Er road, the strength increase of shaped steel, the intensity of the rear rack of combination is corresponding being improved also.Another and cabinet hole changes six sides into by circle, use special six square nuts as and cabinet nut, operation top many, and owing to exposing material limit mouth infolding, whole maintenance install and use and and during cabinet, can effectively eliminate the abrasive hidden danger of hand.

Fig. 1 is the end view drawing of common C shaped steel section bar.
Fig. 2 is the end view drawing of C shaped steel section bar after remodeling.
Fig. 3 is the end view drawing of the utility model C shaped steel section bar.
Fig. 4-1st, and the plan view of special hexagon nut for cabinet.
Fig. 4-2nd, the side view of Fig. 4-1.
Fig. 5 is the C shaped steel section bar end view drawing using as rack column.
In figure, 1 is inner bending limit, the 2nd, and cabinet mounting hole, the 3rd, and the special hexagon nut of cabinet.
Embodiment
Contrast accompanying drawing 3,5, the universal C shaped steel section bar of bending edges in band, its structure is that the one side in steel profile is provided with the groove with 45 ° of limits, in the bottom surface of the groove on 45 ° of limits, be provided with and cabinet mounting hole, the another side of steel profile is provided with two angle steel curved edges, two sides in angle steel curved edges are provided with the modulus mounting hole that modulus value is 20 or 25 pitch-rows, and in steel profile two sides, being also provided with the modulus value corresponding with the modulus mounting hole of angle steel curved edges setting is 20 or 25 modulus mounting hole; In two described angle steel curved edges, be respectively provided with one symmetrical inner bending limit 1.
Described and cabinet is regular hexagon with mounting hole 2.
Contrast accompanying drawing 4-1,4-2, and cabinet with special hexagon nut 3 in order to be used in conjunction with mounting hole with cabinet also.
The twice inner bending limit 1 increasing, make the limit mouth infolding still exposing, not only intensity is better, and thoroughly eliminated the problem that expose on steel limit, making section bar cross section structure be tending towards more perfect rationally has circular hole to change hexagonal hole in the also cabinet hole on original shaped steel in addition, with special six square nuts and hexagon socket head cap screw, interfixes, while having eliminated former and cabinet with plain nut because of C type opening surface little, the difficulty that cannot operate with hand.As long as special six square nuts are inserted in one end, the other end is by bolt precession, and cabinet and cabinet can easily be fixed.
Claims (2)
1. the universal C shaped steel section bar of bending edges in being with, its structure is that the one side in steel profile is provided with the groove with 45 ° of limits, in the bottom surface of groove, be provided with and cabinet mounting hole, the another side of steel profile is provided with two angle steel curved edges, two sides in angle steel curved edges are provided with the modulus mounting hole that modulus value is 20 or 25 pitch-rows, and in steel profile two sides, being also provided with the modulus value corresponding with the modulus mounting hole of angle steel curved edges setting is 20 or 25 modulus mounting hole; It is characterized in that being respectively provided with symmetrical inner bending limit one in two described angle steel curved edges.
