Description

Concrete flowerpot and three-dimensional greening wall formed by same

Technical Field

The application relates to the field of greening walls, in particular to a concrete flowerpot and a three-dimensional greening wall surface formed by the same

Background

With the development of urbanization, buildings are continuously built, and in order to reduce the pollution of the construction process to the urban environment, the construction site and the external environment are usually separated by a greening wall, and the noise can be reduced, the environment can be beautified and the air can be purified by arranging the greening wall.

The flowerpot used on the greening wall generally comprises a plastic flowerpot, a red pottery flowerpot, a glass fiber reinforced plastic flowerpot, a magnesium oxide flowerpot, a sandstone flowerpot, a wood flowerpot and the like, in recent years, the concrete flowerpot is popular with people due to natural appearance, and the outdoor greening wall is greatly influenced by environmental factors, for example, the plastic flowerpot is easy to oxidize and become unstable after being placed outdoors for a long time, the red pottery flowerpot is easy to break in the carrying and installing process and the like, so that the concrete flowerpot is widely applied to outdoor greening in recent years.

In view of the above-mentioned related arts, the inventor believes that when a concrete flowerpot is used to form a greening wall, mortar is generally used to bond the concrete flowerpot, and the greening wall needs to be removed after construction is completed, which causes inconvenience in removing the greening wall, and the removed flowerpot cannot be recycled, which causes a resource waste, thus providing room for improvement.

Disclosure of Invention

In order to facilitate the removal of the greening wall and save resources, the application provides a three-dimensional greening wall surface formed by concrete flowerpots.

First aspect, the application provides a concrete flowerpot, adopts following technical scheme:

the utility model provides a concrete flowerpot, is formed by concrete placement, concrete flowerpot includes the flowerpot body and is used for dismantling the connecting piece of connecting between the flowerpot body, the basin top of flowerpot body seals, the connecting piece is located the pelvic floor of flowerpot body in order to connect the basin top of flowerpot body.

Through adopting above-mentioned technical scheme, because the pelvic floor and the basin top of flowerpot body are connected to the connecting piece for the pelvic floor and the basin top of concrete flowerpot support tightly, the joint action of rethread connecting piece makes concrete flowerpot can connect into a whole, because the connecting piece makes concrete flowerpot can independently dismantle when the construction is accomplished the back and need dismantle, and then makes concrete flowerpot continue to assemble the use, thereby makes the afforestation wall more conveniently be demolishd and practice thrift the resource better.

Preferably, the vertical section of the concrete flowerpot is in a regular triangle shape, a regular quadrangle shape or a regular hexagon shape.

Through adopting above-mentioned technical scheme, because the specific shape that sets up the concrete flowerpot, make the concatenation department of flowerpot can the abundant contact, make the area of connection between the flowerpot great, reduce the gap between the flowerpot, make three-dimensional greening wall more closely knit, and then make the isolated construction site's of three-dimensional greening wall effect better, thereby make further noise reduction, beautify the environment better, make simultaneously support each other between the concrete flowerpot in order to form stable greening wall, make greening wall's stability better.

Preferably, the concrete comprises the following components in parts by weight:
