Description

Technical Field

[0001] This utility model relates to the field of building greening technology, specifically to a modular vertical green wall with a bamboo woven outer skin. Background Technology

[0002] Vertical greening, also known as three-dimensional greening, is the process of planting climbing plants on walls, balconies, windowsills, rooftops, and pergolas to make full use of space, thereby increasing green coverage and improving the living environment. Vertical greening plays a unique role in overcoming insufficient urban green space and improving undesirable environments.

[0003] To address this, Chinese utility model patent CN202421324977.4 discloses a municipal landscape green wall, comprising a fixing base, a green wall body, planting pots, a watering component, and a shielding component. The green wall body is mounted on the fixing base. Multiple sets of planting pots are arranged side-by-side on both sides of the green wall body. The watering component is mounted on the green wall body and located above the planting pots, and includes connecting plates. Multiple sets of connecting plates are slidably mounted on the green wall body. The shielding component is mounted on the green wall body to shield the planting pots. This utility model features adjustable-height sprinklers that provide personalized water supply to each plant, meeting their growth needs; the shields effectively reduce direct sunlight exposure to plant leaves, protecting the plants from damage.

[0004] However, the above-mentioned patented technology has the following drawbacks in application: 1. The watering component relies on a sliding mechanism driven by a motor, which is prone to corrosion or dust accumulation in humid outdoor environments, leading to jamming or failure; 2. The planting pot is not designed with an inclination, resulting in insufficient light utilization by the plants, affecting plant growth. In addition, the planting pot is not equipped with a drainage mechanism, so excess water cannot be drained, which can easily lead to waterlogging in the soil and cause pests and diseases. Utility Model Content

[0005] The purpose of this utility model is to disclose a vertical green wall with modular splicing, controllable water storage and drainage, and adjustable angle, so as to solve the problems existing in the above-mentioned background technology.

[0006] The present invention adopts the following technical solution:

[0007] A modular vertical green wall with a bamboo woven outer skin includes a steel frame and several planting units attached to the steel frame. Each planting unit is a square container with an open top, a hook on the back, and an upwardly sloping placement cavity in the center of the front, into which a planting container is detachably installed. A longitudinal protrusion is fixed on one side wall of the planting unit, and a longitudinal groove complementary to the shape of the protrusion is formed on the opposite side wall. An overflow drain pipe is provided at the bottom of the planting unit, and the inlet of the overflow drain pipe is 2-5 cm above the bottom surface of the planting unit, forming a limited water storage space at the bottom of the planting unit.

[0008] Furthermore, to enhance the aesthetics of the exterior wall, the front of the green planting unit is also covered with bamboo woven fabric.

[0009] Furthermore, to facilitate irrigation, a water and fertilizer pipe is fixed to the side of the steel frame of the wall. One end of the water and fertilizer pipe extends to the ground and connects to the water pump, while the other end extends to the top of the steel frame of the wall and is parallel to the crossbeam of the steel frame. Multiple nozzles are installed on the pipe section parallel to the crossbeam of the water and fertilizer pipe. Each nozzle is located above the green plant planting unit and sprays water directly onto the planting container.

[0010] This utility model has the following beneficial effects:

[0011] 1. Convenience of construction

[0012] The green planting units are independently attached to the steel frame via back hooks, eliminating the need for bolt fixing; adjacent units are mechanically locked together by the cooperation of protrusions and slots to form a continuous wall; modular assembly significantly improves construction efficiency, and individual planting units can be replaced for maintenance, avoiding the waste of time caused by disassembling and assembling the entire structure.

[0013] 2. Resource efficiency

[0014] The water storage space at the bottom of the planting unit (the overflow pipe inlet is 2-5cm above the bottom surface) retains irrigation water / rainwater in the short term. Excess water is discharged in a directional manner through the overflow pipe. The sprinkler head at the top of the water and fertilizer pipe provides precise irrigation to the planting container. The dual water management structure works synergistically: the water storage space buffers the risk of short-term water shortage for plants, and precise sprinkler irrigation reduces ineffective evaporation, thus improving the overall efficiency of water resource utilization.

[0015] 3. Structural stability

[0016] The longitudinal convex bars and the trapezoidal cross-section of the slot form a self-locking structure, which constrains the displacement of the unit in the horizontal direction; the steel frame disperses the vertical load through the crossbeams; the mechanical interlocking effectively resists the lateral wind load, the steel frame provides a rigid support foundation, and the overall structure is adapted to the strong wind environment of high-rise buildings;

[0017] 4. Ecological compatibility

[0018] The 10-30° inclined cavity allows the plant canopy inside the planting container to naturally tilt outwards, and the bamboo woven skin covering the surface of the unit forms a breathable and heat-insulating layer; the inclined angle design expands the plant's light-receiving area and improves ventilation; the bamboo woven layer buffers extreme temperature changes, synergistically improving plant survival rate and landscape harmony;

[0019] 5. Heat insulation and sound insulation functions

[0020] The bamboo woven outer layer itself has excellent heat insulation and sound insulation properties, which can effectively reduce building energy consumption and improve the comfort of the living environment. The woven structure of bamboo provides additional strength and elasticity, resisting wind and reducing external noise interference;

[0021] 6. Combination of Aesthetics and Function

[0022] The woven pattern of the bamboo outer skin can be customized according to customer needs, combining decoration and practicality, so that the green wall not only provides green vegetation space, but also becomes a unique highlight of the building's appearance. Attached Figure Description
