Description

Technical Field

[0001] This utility model relates to the field of dust prevention technology in house demolition, specifically a dust cover for house demolition. Background Technology

[0002] In the process of urban construction and renovation, house demolition is frequently carried out. With the deepening of environmental protection concepts and increasingly stringent requirements for air quality, dust pollution during the demolition process has received more and more attention.

[0003] Traditional house demolition methods generate a large amount of dust, which not only seriously affects the daily lives of nearby residents and reduces their quality of life, but also causes significant damage to the surrounding environment. The flying dust in the air increases the content of inhalable particulate matter, worsens air quality, and poses a potential threat to people's respiratory health. Moreover, the dust will cover the surrounding vegetation, roads, and building surfaces, affecting the urban landscape. In addition, if demolition dust is not effectively controlled, it may also trigger a series of environmental disputes, which is not conducive to the harmonious progress of urban construction. Therefore, we propose a dust cover for house demolition. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a dust cover for house demolition, which has the following beneficial effects:

[0015] 1. This dust cover for house demolition is height-flexible and adaptable to various scenarios. The height of the main rod, intermediate rod, and top rod of the adjustable support frame can be adjusted through height adjustment holes. The position of the horizontal rod is adjusted through the width adjustment hole within the sliding groove of the horizontal rod. This allows the dust cover to flexibly change its height and width dimensions, perfectly adapting to low bungalows, tall multi-story buildings, or houses of different lengths and widths. This height flexibility greatly expands the application range of the dust cover and improves its practicality in various house demolition scenarios. It eliminates the need to customize different dust protection equipment for houses of different sizes, thus reducing costs.

[0016] 2. The dust cover used for house demolition effectively prevents dust, reduces noise, and is environmentally friendly and beneficial to the people. The cover completely encloses the demolition area, preventing dust from overflowing at the source. The dust generated during the demolition process is confined inside the cover, greatly reducing the content of inhalable particulate matter in the air, significantly improving the surrounding air quality, protecting the respiratory health of residents, reducing dust pollution to surrounding vegetation, roads, and building surfaces, and maintaining the urban landscape. At the same time, the dust cover also plays a role in blocking demolition noise to a certain extent, reducing noise interference to the daily lives of surrounding residents, creating a relatively quiet living environment, and promoting the harmonious progress of urban construction.

[0052] Working Principle: Install the dust cover for house demolition correctly according to the diagram. The dust cover mainly consists of the cover body 1 and the adjustable support frame 2 working together. The adjustable support frame 2 serves as the core support structure, with four main rods 3 symmetrically distributed at the bottom. The bottom of each pair of main rods 3 is connected by a horizontal bar 6, and the top connects to the middle rod 4. A top rod 5 is located above the middle rod 4, with adjacent top rods 5 connected by a horizontal bar 8. Adjacent middle rods 4 are connected by a horizontal bar 7, forming a stable and adjustable hollow rectangular frame. The main rods 3 consist of vertical rods 9 and horizontal rods 10. The sliding groove 11 inside the horizontal rod 10 cooperates with the horizontal rod 6. The position of the horizontal rod 6 can be adjusted through the width adjustment hole 12 and the matching bolts, changing the side length of the rectangular frame. To adapt to houses of different widths, the intermediate rod 4 can slide within the groove 13 of the main rod 3 and is fixed with the matching bolt through the height adjustment hole 14 to achieve initial height adjustment. The top rod 5 can slide within the groove 20 of the vertical rod 15 of the intermediate rod 4 and is adjusted again with the height adjustment hole 21 and the matching bolt, thus adapting to houses of different heights in all directions. After the adjustable support frame 2 is adjusted according to the size of the house, the cover 1 is placed on its outside and fixed with ropes or straps. During demolition operations, the cover 1 acts as a barrier, using its physical barrier properties to confine the dust generated during demolition to the internal space of the cover, preventing the dust from spreading to the surrounding environment and thus effectively reducing the pollution of the external air environment by dust.
