Large chandeliers are installed on the structural layers, such as slabs, trusses and beams on the trusses. Small chandeliers are often installed on the sheds or on the reinforcement joists. Whether a single chandelier or a combination chandelier is produced by the luminaire factory, Different from the most, a single chandelier can be installed directly, and the combination chandeliers should be combined after installation or installation. For large-area and strip-shaped lighting, the use of suspension rods and light holders is often used.
Material preparation
(1) Construction materials: The following materials are commonly used.
1 wood (water tanks, wood strips, water panels of different specifications), aluminum alloy (plates, profiles), steel (steel, flat steel, steel), mainly used as supporting members.
2 plastic, plexiglass plate, glass as spacer, exterior veneer and heat sink, copper plate. An electrochemical aluminum plate is used as a decorative member.
3 other accessories such as screws, nails, rivets, finished lamps, adhesives, etc.
(2) Construction tools: pliers, screwdrivers, hammers, electric jigsaws, electric hammers, hand data, rulers, paint brushes, etc.
Structural layer connection
(1) Method of operation: The connection between the embedded part and the transition piece is mainly considered.
1 First embed iron or wood bricks in the structural layer (except for water brick load). The buried position should be accurate and there should be sufficient room for adjustment.
2 Set transition joints on iron and wood bricks to adjust the error of the workpiece, which can be nailed, welded and screwed.
3 Hangers, slings and transition connectors are connected.
(2) Installation precautions: Pay attention to the following three points during installation and construction.
1 If there are multiple chandeliers during installation, pay attention to their position and length. Install the chandelier at the same time as installing the ceiling. This can adjust the position and height of the lamp based on the ceiling joists.
2 The boom can be used for direct and method of casing. The method of adding the pipe is advantageous for the installation, and the roof panel can be ensured to be complete, and only the hole where the pipe is required to be taken out can be drilled. Straight out of the ceiling of the hanging cup, the board surface drilling is not easy to find. Sometimes it is possible to install the boom first and then cut off the panel to install the hole, but it has an effect on the decorative effect.
3 The boom should have a certain length of thread for adjustment. Suspend the light box below the sling boom, pay attention to the reliability of the connection.
Joist connection
The boom, the sling are directly nailed, screwed to the secondary joist, or connected to the vertical grid by the above-mentioned plate surface perforation. Or hanging on the cross joist between the secondary picking grids. The power of the light source used for the ceiling lamp: 40 to 100W for incandescent bulbs and 30 to 40W for fluorescent lamps.
security wall,also called Hesco Barrier.
Originally designed as to prevent dike will be eroded, and flood control, flood control, later to be used as a military fortress, which are widely used in military defense border guard military exercises special explosion-proof network, as the military equipment, used in combat troops in riot gear, temporary fort, prewar command, to replace the traditional manual trenches, can effectively block the attacks of guns and bullets.
it is connected by the spring with Welded Wire Mesh panels to form a cell. It can use a single cell, but also can be connected together to use. It is generally used with the geotechnical cloth.
