Description

Technical Field

[0001] The invention relates to the technical field of electrical lighting of buildings, and in particular to a construction method for a fluorescent lamp strip in a high-space steel cable trough. Background Art

[0002] At present, the installation of lamps in large spaces such as underground garages and distribution rooms is traditionally done by ceiling mounting or hanging rods (hanging chains). However, due to the dense distribution of large-diameter air ducts and water pipes in basements in recent years, it is difficult to ensure the lighting effect of lamps installed on the ceiling. If lamps are installed by hanging rods, the lamps cannot be arranged evenly and the hanging rods are difficult to root and fix, resulting in a low safety factor, considerable construction difficulty, and poor installation effect. Summary of the invention

[0003] The purpose of the present invention is to provide a construction method for a fluorescent light strip in a high-space steel cable trough, which is simple to construct and effectively reduces construction costs and construction period. Low-altitude operations ensure construction safety, greatly improve construction efficiency, and effectively save manpower and material resources.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme: A method for constructing a high-space steel cable trough fluorescent light strip comprises the following steps: Drawing optimization: adopt comprehensive pipeline layout and optimize pipeline direction, use steel cables to fix wire ducts to hang fluorescent lamps; use φ16 wire hangers to strengthen the fixation of metal wire ducts every 12m; Positioning and laying out: Use an infrared laying out instrument to lay out and mark the lines, and determine the on-site positions of lamps, steel cable rings and hangers; Cable pull ring installation: according to the height of the lamp and the width of the wire trough, fix the M8 type hook expansion bolts on the walls on both sides of the space, and the distance between the two hooks is 50mm less than the width of the wire trough; Assemble the steel cable: insert one end of the pre-stretched steel cable into the earring, fold it back and insert it into the heart-shaped ring, and then use two steel cable clips to fix the two ends; screw the screws at both ends of the M6*100 type basket bolt into the nuts, and keep them at the maximum distance to prepare for further adjustment of the tightness of the steel cable; remove the wire tied to the tail end of the steel cable, and pass the steel cable through the basket bolt and earring, fold it back and embed it into the heart-shaped ring, and then use two steel cable clips to fix the two ends; pull up the steel cable and the basket bolt at the same time, and hook the earring at the other end, then tighten the steel cable with a large rope, and start to fix the steel cable on the hook from the middle, and adjust the screw of the basket bolt to make the tightness of the steel cable meet the requirements; Cable duct installation: After the cable duct is assembled, it is laid horizontally on the steel cable, and the two steel cables are evenly stressed on the two corners of the cable duct; after the entire cable duct is installed, all the cable ducts are leveled and straightened, and after the connection is firm, the steel cables are fixed with the inward-turned flanges on the sides of the cable duct; the flanges are cut into 20mm wide openings at intervals of 1 meter, and the cut openings are turned down with electrician pliers, and the steel cables are fixed inside the cable duct to prevent the cable duct from moving on the steel cable; the horizontal and vertical deviations of the cable duct do not exceed 5mm, and the joints are tight, and the cable duct is ensured to be firmly installed without distortion and deformation, and the nuts of the fasteners are on the outside of the cable duct; Wiring in cable trough: When laying out the wires, a special wire laying rack is used to ensure that the wires are not twisted. The power lines of the lamps are drawn out from the pre-buried power pipes, laid horizontally in the cable troughs, and the wires of each loop are bundled into bundles with plastic tie bands. After all the wires are laid, a 500V megohmmeter is used to test the insulation resistance of the wires, and it is ensured that the insulation resistance between the wires and the wires to the ground shall not be less than 0.5MΩ. Lamp installation: When installing lamps, ensure that the center line of the lamp holder coincides with the center line of the wire trough, and make the lamp holder close to the wire trough, and add a 3mm thick rubber pad between the lamp holder and the wire trough for heat insulation; use a pistol drill to drill Ф3.2 holes on the lamp holder and the wire trough, and use Ф3 rivets to fix them, so that each set of lamp holders has 2 fixing points, and one point is fixed at each end of the lamp holder; pull the reserved lamp power cord out of the reserved hole, and after the internal wiring of the lamp holder is completed, cover the lamp holder cover, and then cover the wire trough cover.

[0005] In actual application, the installation height of the lamp is 2.5 meters from the ground.

[0006] Among them, the cross-section of the steel cable is 10mm 2 of steel strand.

[0007] Specifically, the lamps are T5 energy-saving single-tube or double-tube fluorescent lamps.

[0008] Furthermore, when installing a double-tube lamp, the lamp tube bracket has a specification of 1176 mm long × 29 mm wide × 53 mm high, and a 75 mm * 50 mm metal wire trough is selected.

[0009] Furthermore, when installing a single tube lamp, the lamp tube bracket has a specification of 1177 mm in length × 72 mm in width × 65 mm in height, and a 45 mm * 30 mm metal wire trough is selected.

[0010] Compared with the prior art, the construction method of the high-space steel cable trough fluorescent light strip described in the present invention has the following advantages: In the construction method of the fluorescent light strip with steel cable trough in a large space provided by the present invention, since two steel cables are tightened and fixed horizontally, the metal trough is laid on the steel cables, the two steel cables are evenly stressed on the two edges and corners of the trough, the fluorescent lamp is riveted to the bottom of the metal trough, and the wiring of the lamp is carried out inside the lamp; in addition, the amount of hanging rods is directly reduced, avoiding the reservation and pre-embedding of ceiling light boxes and pipelines in the early stage of the project, speeding up the construction progress, and the light strip is horizontal and vertical after hanging, neat and uniform, which is particularly suitable for the installation of light strips with steel cable troughs in large spaces where there are obstacles such as air ducts above the lamps and the brackets cannot take root; therefore, the construction method of the fluorescent light strip with steel cable trough in a large space provided by the present invention changes the wiring method of traditional lamps ceiling-mounted or pole-suspended (chain-suspended), and adopts steel cable troughs to install fluorescent lamps. In the arrangement of lamps in large spaces, the problem of obstruction by air ducts and water pipes, and the inability of lamps to be fixed and rooted is effectively overcome; this construction method makes the installation of lamps more convenient, flexible and reasonable, and can fully guarantee the illumination requirements; at the same time, it ensures the installation quality of fluorescent light strips in large spaces on the construction site. After installation, the light strips are horizontal and vertical, evenly arranged, neat and uniform, and more convenient for inspection and maintenance. It is more suitable for the construction of fluorescent light strips in large spaces such as garages, factories, and distribution rooms; and it effectively reduces the construction cost and construction period, makes the construction operation simple and easy, ensures the safety of construction by low-altitude operations, greatly improves the construction efficiency, and saves the investment of manpower and material resources; in addition, the steel cable trough fluorescent light strip is economical and practical, not easy to damage, and has certain economic benefits.
