Abstract

The present invention provides a quick-assembly windbreak device for preventing storm damage to a low-rise wooden dwelling. The device comprises a scaffold, multiple windbreak nets, and multiple concrete counterweights. In the present invention, the scaffold is used as a base, and the windbreak nets are tied to the scaffold. Through-holes on the windbreak nets block part of a wind gust while allowing part of the wind gust to pass through, such that a strong wind gust is transformed into a weak wind gust, and so does not apply an impact force or a destructive force to a low-rise wooden house located behind the windbreak nets, thereby achieving good disaster prevention and mitigation and residential house protection effects. The scaffold is widely used and so is easily obtained, and can be erected quickly and easily, and the windbreak nets can also be tied to the scaffold quickly and easily. Erecting a scaffold does not require professional skill, and an ordinary resident can erect a scaffold around their house by themselves, and thus all residents and families can use this device. The device can be quickly disassembled, and can serve as a common family emergency tool. The device has a simple structure and low cost, and is suitable for broad promotion and use.

Description

Quick installation wind-proof device for preventing low-rise wooden houses from being exposed to storm disasters

Technical field

The invention relates to the technical field of emergency disaster prevention and mitigation, and in particular to a quick-installed windproof device for preventing low-rise wooden houses from storm disasters.

Background technique

Light wood structure house is a structural form that is widely used in North American residential buildings. It is composed of a uniform and dense connection of specification materials with smaller component sections. It is composed of main structural components (structural skeleton) and secondary structural components (wall panels, building Panels and roof slabs work together to bear various loads, and finally transfer the load to the foundation, which has the characteristics of economy, safety, and flexible structural layout.

A storm is a severe weather phenomenon with very high wind speeds, including tornadoes, tropical cyclones and large-scale extratropical cyclones. Both hurricanes and typhoons refer to tropical cyclones with wind speeds above 33 meters per second. They have different names only because of the different regions where they occur. The strong tropical cyclones generated in the Northwest Pacific and the South my country Sea are called "typhoons"; the strong tropical cyclones generated in the Atlantic Ocean, the Caribbean Sea and the eastern North Pacific are called "hurricanes."

Every year, typhoons or hurricanes cause huge disasters to the coastal areas of China, Southeast Asian countries, Northeast Asian countries and North American countries, including casualties, animal casualties, damage and collapse of buildings, damage and collapse of public facilities, and so on.

Because most residential houses in North American countries (mainly the United States and Canada) are light wooden low-rise houses, their ability to withstand storms is poor, and strong winds can easily cause wooden houses to collapse. After the storm, people still need to rebuild light wooden low-rise houses. Low houses. Although light wooden low-rise houses have the advantages of low cost and quick construction, hurricanes come almost every year, and in some years several times a year, wooden houses are blown down almost every year, and they have to be rebuilt almost every year. All of them collapsed, and the decoration, furniture, home appliances and other properties in the house would also be damaged. This is not a small loss. In this way, all the disaster losses are added together and the disaster occurs almost once a year, which makes the local residents Unbearable.

Therefore, how to protect low wooden houses after receiving a storm disaster warning, block the strong wind from directly blowing on the low wooden houses, and prevent the low wooden houses from being damaged or collapsed in the storm disaster, is a technology in the art Technical problems that people need to solve urgently.

Summary of the invention

The purpose of the embodiments of the present invention is to provide a quick-installed wind-proof device for preventing low-rise wooden houses from storm disasters.

In order to solve the above-mentioned technical problems, the technical solutions provided by the present invention are as follows:

A quick installation wind-proof device used to prevent low-rise wooden houses from storm disasters, including scaffolding, multiple wind-proof nets and multiple concrete counterweights;

The scaffolding is arranged around the wooden low-rise house and facing the direction of the wind, and the scaffolding surrounds the wooden low-rise house. A three-dimensional grid structure formed by connecting rods, vertical sweeping rods and horizontal sweeping rods through connectors;

The wind-proof net is arranged on the scaffold, each wind-proof net is arranged facing the direction of the wind, and each wind-proof net is provided with a plurality of through holes for allowing the wind to pass through, and multiple wind-proof nets are connected to each other Forming a whole windbreak wall surrounding the low wooden house;

The concrete counterweight is pressed on the lowermost longitudinal sweeping rod in the scaffold to improve the fixing force of the scaffold.

Preferably, the scaffolding is a fastener type steel pipe scaffold, a bowl buckle type steel pipe scaffold or a socket type disc buckle type steel pipe scaffold.

Preferably, the windproof net is a strip-shaped metal plate structure, and the widthwise cross-section of the windproof net is a trapezoidal waveform, and the widthwise cross-section of the windproof net is a single crest trapezoidal waveform, a double crest trapezoidal waveform, or a triple crest. The wave crest is trapezoidal in shape, the width direction cross section of the wind screen is between two adjacent wave crests as a wave trough, and the length direction of the wind screen arranged on the scaffold is parallel to the horizontal plane.

Moreover, building scaffolding does not require too many professional skills. Ordinary residents can build it with simple training on site, and tying the windbreak net to the steel pipes in the scaffolding does not require professional skills, so there is no need to wait for professional workers to build it. Ordinary residents can do it on their own. Build scaffolding, tie up and install wind-proof nets around the house, which gives full play to the subjective initiative of the people, and realizes the participation of everyone and every family to resist the storm together and minimize the damage caused by the disaster;

Moreover, the quick installation windproof device in this application can also be quickly disassembled. After disassembly, simple steel pipes, fasteners and windproof nets can be removed. The disassembled steel pipes, fasteners and windproof nets can be placed in a warehouse or other free place. It occupies a relatively small storage space and is a standing emergency tool for the family. When the next storm comes, take out the stored steel pipes, fasteners and wind nets to quickly build and shape, resist the storm, and prevent and reduce disasters;

In addition, the quick-installed windproof device has a simple structure, low cost, and is easy to popularize and apply in a large range.
