How to fix billboards on sloping roofs with tiles
壹、How to avoid an earthquake
1. Outdoors
Choose to squat or lie down in an open area and avoid tall buildings, such as buildings, tall chimneys, and overpasses. etc.; avoid dangerous tall or hanging objects, such as transformers, street lights, billboards, etc.
2. At home
In the building, you should choose a small room and hide next to solid furniture; in a bungalow, you should choose a small room or hide next to solid furniture according to the specific situation. Hide somewhere or run to an open area outdoors. After an earthquake, a house collapse sometimes forms a triangular space indoors, which is a relatively safe place. It includes places with small openings such as under the edge of the kang, under solid furniture, at the base of interior walls, in corners, in kitchens, toilets, storage rooms, etc.
3. Indoors
Keep calm and quickly turn off the power and gas. Grab a pillow or cushion to protect your head and hide in a safe corner; when hiding, do not approach the window or Go up to the balcony. Never jump off a building.
4. School
Do not run outside the classroom. You should quickly cover your head with your school bag, close your eyes, and hide under your desk until the earthquake passes. , move outside the classroom under the teacher's command; when outside the playground, you can squat down and protect your head with your hands.
5. Others
In theaters, gymnasiums, etc.: Squat down or lie under benches; be careful to avoid hanging objects such as chandeliers and fans; use school bags to protect your head; etc. After the earthquake passes, follow the instructions of the staff and evacuate in an organized manner.
In shopping malls, bookstores, exhibition halls, subways, etc.: Choose a sturdy counter, product (such as low furniture, etc.) or beside a pillar, as well as an inner corner, etc. to squat on the spot and use your hands or Protect your head with other things; avoid glass doors, windows, glass showcases or counters; avoid tall and unstable shelves with heavy or fragile items; avoid tall hanging objects such as billboards and chandeliers.

In shopping malls, bookstores, exhibition halls, subways, etc.: Choose a sturdy counter, product (such as low furniture, etc.) or beside a pillar, as well as an inner corner, etc. to squat on the spot and use your hands or Protect your head with other things; avoid glass doors, windows, glass showcases or counters; avoid tall and unstable shelves with heavy or fragile items; avoid tall hanging objects such as billboards and chandeliers.
Rigid foamed polyurethane
Rigid foamed polyurethane is used in roofing projects, both for waterproofing and thermal insulation. effect. Among all building insulation materials, foamed polyurethane is one of the waterproof materials with the lowest thermal conductivity. Its performance characteristics are that the sealing rate of the internal structure is ≥92%, the foamed surface layer forms a smooth film, its closed cell rate is close to 100%, and it has high hydrophobicity; the compre ssion resistance when the density is 40kg/m3 Strength >1.5mpa; certain elasticity, elongation 10%; good adhesion to metal, concrete, masonry, wood, and glass. Its usage characteristics are: rigid foamed polyurethane adopts two methods: on-site injection foaming and composite pre fabricated panels. Injection foaming uses two components to come together during injection and react immediately to form foamed polyurethane. This method can be widely used for on-site foaming. When on-site foaming is not suitable, pre fabricated composite boards can be used, and the gaps between the boards can be filled with foaming guns, which also works well.
Scope of use: Rigid foamed polyurethane can be used in a variety of roofing projects. The base layers used are mainly cast-in-place concrete slabs, pre cast concrete slabs and cement mortar leveling layers. There are polyurethane foamed separately on site, which serves as both a waterproof layer and an insulation layer; some serve as one of the waterproof layers and are also an insulation layer, compounded with waterproof membranes or waterproof coatings; there are also waterproof coatings, waterproof membranes, Three kinds of foamed polyurethane materials are combined to form a waterproof and thermal insulation layer. The main method of sloping roof is to foam the base concrete and then hang tiles on it. The fundamental way to solve the problem of thermal insulation of flat roofs is to use structural slope finding in the design of roof structures using rigid foamed polyurethane, especially cast-in-situ concrete roofs.
Six new roof waterproofing materials have become the focus of waterproof decoration
Biaxially oriented polyvinyl chloride panels
Usage scope: biaxially oriented polyvinyl chloride panels are divided into colored and colorless It can be used for waterproofing of roofs of large public buildings, industrial plants, sports venues, greenhouses for flower planting and aquaculture, bus shelters, pavilions, etc. It can also be used for indoor screens, soundproof curtain walls, safety sheds, house walls, and guardrails. , partition walls, construction site safety barriers and tunnels, etc.
Co-extruded sandwich foamed polyvinyl chloride tiles
Scope of use: It can be used for sloping roofs of public buildings, residential buildings, factories, etc., and can also be used for interior and exterior decoration and partitions of buildings. The thickness of the tiles is 2~20mm (the current production is mainly 3~5mm), the width is 880-1040mm, and the length can be made according to requirements. The color of the tiles can be formulated in the raw materials or spray-painted after extrusion.
Colored profiled steel plates
Scope of use: Suitable for building roof panels and wall panels, especially for roofs and enclosure structures of large-span factories, warehouses and mobile housing buildings.
Polycarbonate panels
Scope of use: Can be used for interior and exterior decoration of building roofs, bus shelter roofs, walls, partitions, curtain walls and other projects, as well as greenhouses, public telephone booths, advertising Signs, light boxes and display layout and other facilities.
Thermal insulation and waterproof roof panels
Thermal insulation and waterproof roof panels are self-waterproof roof panels made in pre fabricated factories. Colorful paint can be sprayed on the panels. This board is composed of steel frame ribs and waterproof layer, thermal insulation layer and fiber or steel wire.
