This application discloses a retractable smoke curtain, belonging to the technical field of smoke curtains. It includes a fixed frame with a telescopic mechanism inside. The telescopic mechanism includes a first telescopic section fixedly installed inside the fixed frame. A second telescopic section is slidably connected inside the first telescopic section. Both the first and second telescopic sections have two sets of slide rails inside, with sliders slidably connected to the slide rails. A first spring is installed at the top of each slider and is mounted on the top of the telescopic mechanism. The second telescopic section is slidably connected to the first telescopic section via the two sets of sliders located inside the first telescopic section. A screw is threadedly connected to the bottom of the first telescopic section below one set of sliders, and a stop block is rotatably connected to the top of the screw. An elastic limiting mechanism is provided on one side of the bottom of each set of first telescopic sections below one set of sliders. This application improves the flexibility and adaptability of smoke-blocking materials through the telescopic mechanism.

A novel fiber concrete polyurethane fabricated thermal insulation wallboard relates to a building wall material and comprises an outer layer A, an inner core and an outer layer B. The inner core is located between the outer layer A and the outer layer B. The outer layer A is provided with an embedded convex block, and the outer layer B is internally provided with an embedded groove. The thermal insulation performance is achieved, polyurethane is adopted as a core thermal insulation material, and the thermal conductivity is low. The heat conductivity coefficient of the aerogel heat insulation felt is extremely low, and the normal-temperature heat conductivity coefficient is about 0.017 W / (Km) and is 3-5 times that of a traditional material; the heat conductivity coefficient of the novel polyurethane insulation board is also very low, and when the density of the hard polyurethane is 35-40 kg / m, the heat conductivity coefficient is only 0.018-0.024 w / (m.k).

The invention discloses a composite air pipe structure lined with a fire-resistant heat-insulating layer and an installation and construction method of the composite air pipe structure. The composite air pipe structure comprises a left-side anti-corrosion metal air pipe, a right-side anti-corrosion metal air pipe and a magnesium fire-proof plate, and one side of the left-side anti-corrosion metal air pipe is fixedly connected with a first angle steel flange through a bolt; a first through groove and a sixth through groove are symmetrically formed in the first angle steel flange; according to the invention, the left side anti-corrosion metal air pipe with the anti-oxidation coating is added by taking the galvanized plate as a base material, so that the anti-corrosion capability and the weather resistance are improved, and the service life is prolonged; all the used materials are A1-grade non-combustible, so that the fire resistance is higher, and the potential safety hazard is eliminated; the rock wool and the fireproof plate cover the outside of the left anti-corrosion metal air pipe, the dead weight is reduced by 50%, the building load is effectively reduced, the building cost is saved, the left anti-corrosion metal air pipe is provided with the fire-resistant heat insulation layer, secondary fireproof wrapping is not needed, construction is easy and convenient, the construction period is shortened by more than two times, the construction quality is effectively improved, the building space is saved, and the building layer height utilization rate is improved.
