The utility model discloses a low-voltage power cable fixing bracket, which comprises an L-shaped angle steel and an aluminum row. The aluminum row is composed of straight sections at both ends and a circular arc section in the middle. The straight sections at both ends are connected to the horizontal section of the L-shaped angle steel through the bolt and nut assembly. The bolts in the bolt and nut assembly are through-thread bolts. The thickness of the arc section in the middle of the aluminum row is 4-6mm, and the chord length is 20-30mm. , The diameter is 50-60mm, and the bolt spacing on the straight sections at both ends of the aluminum row is 60-80mm. The utility model has the advantages of simple structure, convenient installation and disassembly, adopts the aluminum row to clamp the low-voltage power cable, does not generate eddy current, does not cause power loss, achieves the effect of energy saving, has a good effect of clamping the cable, and can be applied to all current Low-voltage power cables are universally applicable.
Description
Technical field
The utility model belongs to lv power cable laying technology field, especially relates to a kind of lv power cable fixed support.
Background technology
At present, during by building or intensive residential building cabling, space, ground is limited, shaft tower and overhead wire can not be erected, burying arrange ment difficulty of construction is also very large, and therefore, workmen adopts angle bar frame to lay along structures such as bodies of wall, utilize U-shaped silk to be stuck on cable, then tighten two nuts and cable is fixed on angle bar frame.U-shaped silk needs to choose according to the external diameter size of cable, if need the cable of fixing multiple different wire diameter in construction, just need the U-shaped silk choosing a variety of different size, construction material demand in engineering can be caused in actual applications to become complicated, workmen also will distinguish the support of different model in construction in addition, increases extra work amount, reduces operating efficiency, increase construction period, all adverse influence is caused to construction investment, income.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide the lv power cable fixed support that a kind of structure is simple, reasonable in design, result of use is good.
For achieving the above object, the utility model adopts following technical scheme:
A kind of lv power cable fixed support, it comprises L shape angle steel and aluminium row, aluminium row be made up of two ends flat segments and middle part arc section, aluminium ranking above the horizontal segment of L shape angle steel and aluminium row two ends flat segments be all connected by the horizontal segment of bolt and nut component with L shape angle steel, bolt in bolt and nut component is harness cord bolt, the thickness of the middle part arc section of aluminium row is 4 ~ 6mm, chord length is 20 ~ 30mm, diameter is 50 ~ 60mm, and the pitch of bolts in the two ends flat segments of aluminium row is 60 ~ 80mm.
Owing to adopting technical scheme as above, the utility model has following superiority:
This lv power cable fixed support, its structure is simple, novelty reasonable in design, cost of manufacture is low, installation, convenient disassembly, aluminium row is adopted to clamp lv power cable, because aluminium row is nonferromugnetic material, the change magnetic flux that in cable, alternating current produces cannot form closed-loop path in " bolt-L shape angle steel-bolt-aluminium row ", therefore can not produce eddy current, can not energy loss be caused, reach energy-conservation effect; The selection of the middle part arc section thickness of aluminium row not only ensures fastening strength but also can not bending be out of shape, the choose reasonable of the pitch of bolts in the two ends flat segments of the chord length of arc section, diameter and aluminium row, cable outer surface is reliably close to arc section, strengthen clamping effect, can be applicable to lv power cables all at present, universality is strong, effectively can improve efficiency of construction, shorten construction period, relatively improve construction investment, income.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1(a, b)-harness cord bolt; 2-arc section; 3(a, b)-flat segments; 4-cable; 5-horizontal segment; 6-vertical section; 7-screwed hole.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, this lv power cable fixed support, it comprises L shape angle steel and aluminium row, aluminium is arranged and is made up of flat segments 3a, the flat segments 3b at two ends and middle part arc section 2, aluminium ranking above the horizontal segment of L shape angle steel and aluminium row two ends flat segments 3a, flat segments 3b be connected with the horizontal segment 5 of L shape angle steel respectively by harness cord bolt 1a, harness cord bolt 1b and plain cushion, spring pad, nut, the thickness of the middle part arc section of aluminium row is 4 ~ 6mm, chord length is 20 ~ 30mm, diameter is 50 ~ 60mm, and the pitch of bolts in the two ends flat segments of aluminium row is 60 ~ 80mm; The horizontal segment 5 of L shape angle steel, vertical section 6 offer the screwed hole 7 passed for expansion bolt.
The diameter of above-mentioned aluminium row middle part arc section increases with the increase of chord length.
When the utility model lv power cable fixed support uses, first expansion bolt is adopted to be fixed on body of wall by the horizontal segment 5 of L shape angle steel, vertical section 6, then according to cable size, harness cord bolt 1a is installed in advance, cable 4 being put into aluminium arranges between the horizontal segment of middle part arc section 2 and L shape angle steel again, fastening harness cord bolt 1b, clamping cable.
By adjusting the nut on above-mentioned two harness cord bolts, the cable of different model can be clamped.
The cable that the utility model lv power cable fixed support can be fixed comprises twin cable that external diametrical extent is 14.88mm ~ 37.2mm and external diametrical extent is the quad of 16.25mm ~ 60mm.
