Technical field
The utility model belongs to technical field of buildings, particularly a kind of roof top garden large-scale tree fixed structure.
background technology
Along with urban population sharply expands, but reduce year by year in the greenery patches of answering in contrast.The environmental deterioration grievous injury that various pollutions, tropical island effect etc. cause the physical and mental health of urban human.When the urban ground that can be used to afforest is less and less, enlightened people successively recognizes the 5th face---roof of building both at home and abroad.Utilize plant characteristic and its distinctive environment regulatory function alleviate city underlying surface harden urban heat land effect that phenomenon brings, alleviate a series of "urban disease"s that affect urban sustainable development such as municipal pollution, adverse weather.Therefore,, in the city of an inch of land is an inch of gold, we advocate and carry out roof greening.Roof greening can be construed broadly into as carry out landscape architecture, the general designation of planting plants on all kinds of buildings, on structure, on enclosure wall, on the roof of bridge, viaduct etc., balcony, balcony, balcony or large-scale artificial artificial hillock massif.Can say roof greening, it is the combination of building and garden arts, can effectively make up the deficiency of ecotope in artificial environment construction, set up continuous vertical planting system, increase urban afforestation level, form new urban look, and provide real huge " oxygen store " and the pleasing outside environment of having a rest for city.Roof greening has obvious feature: improve the ecological environment and (as developing space, save soil; Gu carbon oxygen release, reduces " tropical island effect ", increases air humidity, holds receipts rainwater effect, absorbs pernicious gas, reduces noise, bactericidal action); Beautify the environment; Protection building etc.
About planting construction technology aspect, domestic is main mainly with herbaceous plant, shrub plantation, for tree support technology, domestic scholars is carried out the Research on Supporting Techniques of ground trees more, also nobody studies the tree support technology in roof greening, when roof planting large-scale tree, in the situation that meeting strong wind, trees are very easily blown down by strong wind like this.
summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of simple in structure, steadiness good, wind resistance is strong roof top garden large-scale tree fixed structure.
The purpose of this utility model can realize by following technical proposal: a kind of roof top garden large-scale tree fixed structure, it is characterized in that, comprise the soil horizon being laid on roof, in soil horizon, be provided with two symmetrically arranged substrates, described substrate is comprised of Plug Division connected vertically and extension, described Plug Division is inserted solid in soil horizon, extension is fitted in soil horizon upper surface, on every substrate, be provided with baffle plate, described baffle plate is comprised of vertically disposed connecting portion and stop part, described connecting portion laminating is arranged on extension, two stop parts are all circular-arc and surround formation one for holding the cylindrical region of trees trunk.
In above-mentioned roof top garden large-scale tree fixed structure, on substrate extension, offer some equally distributed through holes.
In above-mentioned roof top garden large-scale tree fixed structure, on substrate extension, offer the parallel equally distributed installing hole one of some rows, on baffle plate connecting portion, offer the installing hole corresponding with installing hole one two, and described baffle plate and substrate is connected by timber penetrating mounting holes one and installing hole two-phase and described timber lower end is inserted in soil horizon.
In above-mentioned roof top garden large-scale tree fixed structure, on substrate Plug Division and baffle plate connecting portion, repave and be provided with one deck soil horizon and this edaphic upper surface lower than timber upper end.
Compared with prior art, the utility model by inserting intrinsic substrate in soil horizon, and the extension of substrate is fitted on soil horizon, baffle plate is installed simultaneously on substrate, by the stop part of two baffle plates, surround and form a cylindrical region, thereby the trunk that is planted in the trees in soil horizon is surrounded, thereby in the situation that meeting strong wind, play the effect of the firm trees of keeping out the wind and the situation that stops trees to be collapsed, avoid trees to be blown over by the wind.

embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, this roof top garden large-scale tree fixed structure comprises the soil horizon 2 being laid on roof 1, in soil horizon 2, be provided with two symmetrically arranged substrates 3, wherein substrate 3 is comprised of Plug Division 31 connected vertically and extension 32, Plug Division 31 is inserted solid in soil horizon 2, extension 32 is fitted in soil horizon 2 upper surfaces, on every substrate 3, be provided with baffle plate 4, baffle plate 4 is comprised of vertically disposed connecting portion 41 and stop part 42, connecting portion 41 laminatings are arranged on extension 32, two stop parts 42 are all circular-arc and surround formation one for holding the cylindrical region of trees trunk.
By insert intrinsic substrate 3 in soil horizon 2, and the extension 32 of substrate 3 is fitted on soil horizon 2, baffle plate 4 is installed simultaneously on substrate 3, by the stop part 42 of two baffle plates 4, surround and form a cylindrical region, thereby the trunk that is planted in the trees in soil horizon 2 is surrounded, thereby in the situation that meeting strong wind, play the effect of the firm trees of keeping out the wind and the situation that stops trees to be collapsed, avoid trees to be blown over by the wind.
Further, on substrate 3 extensions 32, offer a plurality of equally distributed through holes 33, when rainy day, rainwater can flow in the soil horizon 2 being covered by substrate 3 by through hole 33, thereby guarantee that soil horizon 2 integral levels are sufficient, do not affect the normal growth of trees.
Further, on substrate 3 extensions 32, offer the parallel equally distributed installing hole 1 of many rows, on baffle plate 4 connecting portions 41, offer the installing hole corresponding with installing hole 12 43, and baffle plate 4 is connected with installing hole 2 43 by timber 5 penetrating mounting holes 1 mutually with substrate 3, according to the size of different trees trunks, the installation site of regulating fender 4 on substrate 3, and with timber 5, baffle plate 4 and substrate 3 are fixed together, when timber 5 is installed, knock timber 5 is inserted in soil horizon 2 its lower end simultaneously, thereby substrate 3 and baffle plate 4 can be firmly fixed together, strengthen baffle plate 4 for the fixedly effect of trees.
As shown in Figure 3, can on substrate 3 Plug Divisions 31 and baffle plate 4 connecting portions 41, repave and be provided with one deck soil horizon 2, so just, substrate 3 and baffle plate 4 connecting portions 41 can be buried in soil horizon 2, from only seeing in appearance baffle plate 4 stop parts 42, thereby do not affect the overall appearance in garden, when laying this soil horizon 2, require the upper surface of this soil horizon 2 lower than timber 5 upper ends, like this in the trees chap of growing tall, while needing the installation site of regulating fender 4 on substrate 3, by being exposed at the timber 5 of soil horizon 2 outward, can differentiate the installation site of original baffle plate 4, conveniently extracting timber 5 readjusts.When substrate 3 covers in soil horizon 2, on substrate 3, the through hole 33 for water flowing can be used for ventilation originally, guarantees the gas permeability of upper and lower two-layer soil.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
