Description

  The present invention relates to a mounting bracket used for wall greening and a wall greening body provided with the mounting bracket.

  In recent years, especially in urban areas, the area covered with man-made objects such as concrete and asphalt has increased, and the so-called heat island, where the temperature of the city and its surroundings rises with the increase in greenhouse gas emissions. The phenomenon is a problem.

  As one of the mitigation measures for this heat island phenomenon, or in addition to this mitigation measures, greening the rooftops and walls of public buildings such as buildings, condominiums, and station buildings for the purpose of improving the cityscape. So-called wall greening is being promoted in many ways. This wall greening is said to have an effect of reducing the solar radiation energy radiated to the outside air on the wall surface or returned to the building. In addition, when the water absorbed from the roots is transpired from the pores, the heat is removed as vaporization heat, so the green area increases due to the greening of the rooftop and walls, which is expected to alleviate the heat island phenomenon. ing.

  By the way, the wall greening method (construction method) that has been put to practical use so far is mainly the following three methods, namely, the growth auxiliary materials (nets, wires, etc.) are installed on the wall surface and the vines are planted there. There is a climbing method, a planting method that attaches a planter or the like to the upper part of the wall surface and hangs the plant down to cover the wall surface, and a foundation molding method that installs a planting base on the wall surface. .

  Among them, the climbing method and the drooping method require less equipment for greening, so the installation cost is lower than the method using foundation molding, while the entire wall surface is covered with plants. There is a problem that it takes a long time.

  On the other hand, while the method using the foundation molding can install the planting base on the wall surface and at the same time green the wall, it requires such a planting base, and furthermore, a frame body for installing them. Etc. need to be assembled independently from the wall surface, and there is a problem that the installation cost becomes very expensive.

  From the above, the entire wall surface is covered with the plant while applying the climbing method and the drooping method, which are cheaper to install, rather than the method of foundation molding, which can be very expensive to install. Technological development is underway to shorten the time until it is released as much as possible (or to increase the coating speed of plants).

  As technology development for accelerating the coating rate of plants, selecting plants with high climbing activity and drooping activity, developing growth aids that promote plant climbing and drooping, The installation method has been improved.

  Plants that climb the wall and have a high climbing activity include adhering and adhering vines such as hederas and giant mushrooms that stretch by adsorbing and adhering roots to the wall. It is possible to select a vine plant with a vine winding property, such as jasmine or mube, which is climbed with a vine or beard wound around a support such as a wire.

  As for the growth auxiliary material, for example, as disclosed in Patent Document 1, there is a technique for attaching a greening panel made of palm fiber to a wall surface to be greened as a climbing aid. On the surface of this greening panel, a straight wire is attached so as to intersect the corrugated wire at the convex part of the corrugated wire and the wire, and when the vine grows, the vine grows from the green mat. A grid that protects against falling off is formed on the front surface of the greening panel. Moreover, in patent document 2, the shape of the stainless steel wire which the vine plant of winding property tends to wind is disclosed.

  The technologies disclosed in these Patent Documents 1 and 2 relate to a greening device specialized for either an adsorption / adhesion type or a vine having a vine-climbing nature, and simultaneously climbing plants having different growth types. In other words, it is not possible to cope with, for example, climbing both an adsorption / attachment-type vine plant and a vine-like vine plant at the same time.

  In addition, in patent document 3, the wall surface greening apparatus provided with the wall surface in which the plant growth path which induces the growth of a vine plant to the upward direction was formed, and the lattice-like plant support wall stretched in front of the wall surface. It is disclosed. Here, adsorbing and adhering vines are planted on the plant growth path, and vines are growing on the plant support wall, and two types of growth aids that are compatible with different types of vines are provided. A greening device. However, the plant elongation path, which is a component of the plant, is formed by a cement-molded plate or the like, and it is supposed that a paint containing granules is applied to the surface so that the adhering vines are easy to adhere. For this reason, depending on the type, it is not possible to cope with plants that do not like to adhere to cement boards or the like. In addition, when planting an existing wall, it is necessary to install a standing wall-like planting device with unevenness made of cement molding board or the like separately in front of the existing wall. Although there is a problem, the merit is offset even though the climbing method is selected to reduce the installation cost.
