Description

Technical Field

[0001] The invention belongs to architectural garden support technology, and in particular relates to a tree fixing system for an aerial ecological courtyard. Background Art

[0002] In the aerial ecological courtyard designed on the balcony of a building, the space of the green courtyard or green platform is greatly increased, so trees can be planted on the green courtyard or green platform. When trees are planted in the soil on the ground, they can take root deep in the soil to maintain their stability. However, in the aerial ecological courtyard of a building, due to the load-bearing strength of the building structure, the thickness of the soil layer laid on the platform is generally not more than half a meter. Therefore, there are two problems with planting trees in the aerial ecological courtyard:

[0003] (1) Trees are taller than shrubs and are easily affected by windy weather. When trees are exposed to strong winds in a certain direction, they may be blown down or tilted due to insufficient support. Therefore, during the tree planting process in ecological buildings, it is necessary to use external support structures to fix the main trunk upright and adjust the tree posture to prevent its center of gravity from being unstable and tilting or falling, so that it can grow stably.

[0004] Traditional tree supports mainly use ropes, wires, plastic belts to tie or bundle tree trunks, or use long iron nails, nails, etc. to nail into the tree trunks, or use multiple pieces of iron sheets to clamp and clamp to adjust the support diameter, and then connect the diagonal support of fir, wooden squares or steel pipes; the tying, bundling and iron clamps are easily loosened and aged after being used for a period of time under wind load, and the support is obviously not firm and unstable; the fixed support method of drilling long nail holes on the tree trunks obviously damages the bark and the internal structure of the branches, which will rot the trees, hinder the transportation of nutrients and water to the trees and affect their healthy growth; in the process of the tree trunk tilting, it is not convenient to adjust the support status of the tilted tree trunk; in addition, multiple trees will be planted in the same green courtyard or greening platform, and the independent support structure has the defects of insufficient radial adjustment space for the trees, insufficient support for the expanded combined tree group, and the inability to reuse the support structures.

[0005] (2) The soil cover of the aerial ecological courtyard is relatively thin, and the soil space available for trees to take root and fix is ​​small. The root system is not stable enough. The upper structure of slightly larger trees has large self-weight or wind resistance. In order to achieve their stable growth when planted in gardens or courtyards, the root system of the trees needs to be deeply covered with soil to prevent them from being covered with loose soil, unstable center of gravity, or being blown down or tilted by strong winds.

[0006] The current underground root fixing method basically uses straw ropes, cloth strips, non-woven fabrics and other bindings to fix the tree root ball to bamboo poles, wooden squares and other materials buried in the soil layer. The strength of the bindings is insufficient and it is easy to break during the underground construction and later stress. The length of the insertion or embedding into the soil layer near the tree pit is short, and the soil ball can only contact or affect a small amount of nearby soil. At the same time, the bamboo poles, wooden squares, straw ropes, cloth strips, non-woven fabrics and other bindings are easily corroded, aged and damaged when soaked in moist and acidic soil media, and the root ball wrapped will lose its stable root fixation quickly. In addition, the soil covering depth is not enough, and the soil ball becomes loose during the erosion and inflow of rainwater, causing the soil attached to the soil ball to be lost. The above factors will cause the root system to become loose and unstable, and it may tilt or fall when encountering a certain wind resistance, and it is impossible to truly achieve the purpose of root fixing and planting slightly larger trees and purifying the air, beautifying the environment, absorbing and reducing noise. Summary of the Invention

[0007] The technical problem solved by the present invention is to provide a novel tree fixing system for the problem that the trunks and roots of trees planted in the aerial ecological courtyard on the building are not firmly fixed.

[0008] The present invention is implemented by the following technical solutions:

[0009] The tree fixing system of the aerial ecological courtyard includes a trunk support device and an underground root fixing device;

[0010] The tree trunk support device includes an annular support and several groups of telescopic support rods connected to the annular support through arm rods; the annular support is sleeved on the outer periphery of the tree trunk, the arm rod is provided with a hinge seat and is hingedly mounted on the annular support through the hinge seat, one of the arm rods with a force arm end relative to the hinge seat is provided with a support plate facing the tree trunk, and the other force arm end is connected to the telescopic support rod, the supporting force of the telescopic support rod on the tree trunk is transmitted to the support plate through the lever action of the arm rod, and acts on the tree trunk through the support plate, and through the installation and deployment of multiple telescopic rods, and the extension or shortening movement, the leverage effect is used to drive the multiple arm rods to be hinged and rotated, thereby prompting the support plate to fit and clamp the main trunk from multiple directions, thereby realizing wind and rain-resistant traction support all around and realizing reliable support of the tree trunk;

[0011] The underground root fixing device includes a protective cage for accommodating a soil ball wrapped around the roots of the transplanted tree and a telescopic base fixedly connected to the protective cage. The telescopic base is provided with a plurality of telescopic bottom rods that extend telescopically toward the outside of the protective cage. The protective cage and the soil ball wrapped around the roots of the transplanted tree are buried deep in the tree pit together, and the telescopic bottom rods on the telescopic base are extended and inserted into the soil layer around the tree pit, thereby connecting the tree roots to the telescopic base, thereby achieving reliable fixation of the tree roots.

[0012] The tree fixing system in the above scheme further includes a base set outside the tree planting location, the base is fixed to the building floor of the aerial ecological courtyard, and is formed by integral casting with the floor or prefabricated separately. The base is a circular or polygonal ring seat surrounding the tree trunk, and several telescopic support rods are hinged and anchored on the base along the circumferential direction of the tree trunk. The bottom of the base is circumferentially distributed with through holes for the telescopic bottom rod to pass through and fix.

[0013] The tree fixing system in the above scheme further includes the telescopic support rod comprising a threaded sleeve and a screw rod connected to both ends of the threaded sleeve by threads, the threaded sleeve and the screw rods at both ends are matched with threads in opposite directions, the screw rod is provided with a locking nut for locking the screw rod and the threaded sleeve, and a connecting piece is provided on the outer end of the screw rod, and the telescopic adjustment can be achieved through the screw rods at both ends by rotating the threaded sleeve.

[0014] The tree fixing system in the above scheme, further, the annular support includes at least two spliced ​​annular seats, and the end faces of the spliced ​​and connected ring seats are provided with mortise and tenon structures that fit together with each other. The annular seats are spliced ​​together at the splicing point to form a fixed shaft seat, and the annular seats are locked and fixed by a detachable hinge shaft. The outer circumference of the annular support is evenly provided with several groups of fixed shaft seats for installing arm rods, and the hinge seat of the arm rod is hinged to the fixed shaft seat through the hinge shaft. The fixed shaft seat and the hinge shaft are used to connect and lock the ring seats, which saves the space structure on the annular support and avoids the need to set up an additional connection structure between the ring seats.

[0015] In the tree fixing system of the above scheme, further, the telescopic base adopts a polygonal frame inscribed on the bottom circumference of the enclosure cage, and the telescopic bottom rod is slidably assembled in the frame cavity on each side of the telescopic base, retracting and extending from the corner point position of the frame along one of the side length directions.

[0016] The tree fixing system in the above scheme is further provided with a guide groove on the frame of the telescopic base along the sliding direction of each telescopic bottom rod, the telescopic bottom rod is provided with a thrust plate extending out of the guide groove, and a limit sleeve is fixed to the telescopic bottom rod, the limit sleeve is threadedly connected to a locking screw passing through the guide groove, the nut of the locking screw extends out of the guide groove, and the telescopic bottom rod is locked in the telescopic state by the locking screw and the limit sleeve.

[0017] The tree fixing system in the above scheme further comprises support bases that are overlapped or staggered and fixed above and below, wherein the upper support base and the lower support base adopt polygonal frames of the same shape, and the telescopic bottom rods at the same corner point of the two support bases are staggered along the directions of two adjacent sides, that is, on the longest side of the inscribed circle frame, thereby maximizing the travel of the telescopic rods and improving the support stability of the telescopic base for the tree by increasing the number of telescopic rods.

[0018] In the tree fixing system of the above solution, further, the outer end of the telescopic bottom rod is provided with a pointed shovel to reduce the resistance of the telescopic rod when extending and inserting into the soil layer.

[0019] The tree fixing system in the above scheme is further provided with an upward screw at a position where the frame of the telescopic base is connected to the bottom circumference of the enclosure cage, and a screw hole is provided at the bottom of the enclosure cage for docking with the screw and passing through. The telescopic base and the enclosure cage are fixedly connected by a nut.

[0020] The tree fixing system in the above scheme is further characterized in that the enclosure cage is spliced ​​with several hollow structure enclosure pieces, and the enclosure pieces are provided with mutually interlocking slots and ridges on the splicing surface, and the splicing position is located in the area connected to the telescopic base. The screw on the telescopic base is a U-shaped double-headed screw, and the U-shaped double-headed screw passes through the bottom of adjacent spliced ​​enclosure pieces at the same time, fixing the telescopic base to the enclosure cage while splicing and fixing the enclosure pieces, and screw holes are reserved at the same position on the top of the cage piece.

[0021] The tree fixing system in the above scheme is further characterized in that the enclosure pieces of the enclosure cage are made of flat steel and hollow tube profiles to form a steel hollow structure, and the interior of the tube cavity of the profile is connected to a water and nutrient solution irrigation system at a temperature required for the growth of tree roots.

[0022] The tree fixing system disclosed in the present invention is aimed at planting trees in aerial ecological courtyards on buildings. It fixes the trees from the trunk and root system respectively. By setting a base integrated with the building floor around the tree, the tree support device and the underground root fixing device are anchored and fixed together. The base can also serve as a flower bed structure for the tree.

[0023] In the tree support device, the telescopic rod, which serves as the supporting structure, is connected to the tree trunk via an arm mounted on a ring-shaped support. The supporting effect of the telescopic rod on the ring-shaped support is distributed through the support plate on the arm, reducing the load on the ring-shaped support. At the same time, the support plates in multiple directions support and protect the tree trunk, reducing the unidirectional load on the tree trunk. The support plates of the arm are clamped and supported tightly against the main trunk of the tree. Wind loads are transmitted through the arm and the telescopic rod to the fixed planting ground or adjacent trees for shared support. Interstitial support can also be provided. In later use or during the growth of the tree, the support force can be strengthened or loosened by adjusting the telescopic action of the telescopic rod as needed. The support effect on the tree trunk is achieved through the lever action between the telescopic rod and the arm. The support effect on the tree trunk can be easily adjusted by controlling the extension and contraction of the telescopic rod. The telescopic rods can be flexibly installed to achieve effective support for the tree trunk in different environments.

[0024] The trunk support device is set above the soil layer where the trees are planted. If conditions permit, it does not occupy the underground and lower support space. The support device can also be installed individually or multiple times on the main trunk of a single tree, and is connected to the ground prefabricated foundation, embedded parts, walls, courtyard beams and slabs, columns, and adjacent tree support devices. For aesthetic reasons, it can also be sprayed with anti-corrosion paint that is the same color as the tree.

[0025] In the underground root fixing device, the telescopic base is a frame with a protective cage as an inscribed polygon, with a double-layer structure. When the telescopic rod is retracted, it will not affect the installation of the telescopic base in the tree pit that matches the cross-section of the protective cage. The telescopic base is fixed to the bottom of the soil ball wrapped around the root system along with the protective cage. The longest side of the inscribed equilateral triangle frame is used to achieve the longest stroke of the telescopic rod. It extends in multiple directions and embeds into the dense soil layer around the tree pit, and extends to multiple directions. The underground device maximizes its pull-out resistance and anti-overturning stable surface, ensuring that the telescopic base provides the maximum support range for transplanted trees, and can achieve a soil covering and stabilization effect that is nearly 6 times larger than the original tree pit.

[0026] The hollow cage structure is welded from flat steel, corrosion-resistant steel sections, or integrally cast. The annular cage structure securely encloses the soil ball and secures the taproot, effectively preventing soil loss from rainwater intrusion. Construction is segmented, making assembly easy. Components are treated with corrosion-resistant metal or made of corrosion-resistant materials. As the tree's roots grow and elongate, they can be integrated with the hollow cage or prefabricated separately. The base can be circular, triangular, or polygonal, creating a long-term, stable, and secure root foundation. Depending on the environment, the cage can be constructed from hollow sections of varying wall thickness. Internal tubing connects to an irrigation system for water and nutrient solutions required for root growth. Precision drip irrigation within the cage's annular pipes near the covered roots effectively increases water and nutrient utilization, improves soil permeability, and regulates soil temperature near the roots, controlling winter warmth and summer coolness. This system also meets irrigation needs for planting.

[0027] In summary, in the tree fixing system of the present invention, the tree is fixed as a whole from the trunk and root system respectively. The whole system is easy to assemble and disassemble, the support is firm and reliable, and the expansion combination is strong. It has obvious effects on the transplanting, planting and fixing of large trees. It can not only be used in the aerial ecological courtyards of buildings, but also has broad market application prospects in landscaping and other aspects.

[0063] Example 1

[0064] See also Figure 1 The tree fixing system acting on a single tree in the figure is a specific embodiment of the present invention. The tree is transplanted and planted on the soil layer laid on the building floor 92 of the building ecological sky courtyard. The tree fixing system includes a trunk support device, an underground root fixing device and a base 9. The trunk support device and the underground root fixing device are used to fix the trunk 4 and the root system of the tree respectively to ensure the stable growth of the tree in the ecological sky courtyard.

[0065] The trunk support device includes an annular support 1 and several groups of telescopic struts 3 connected to the annular support via arms 2; the annular support 1 is sleeved around the periphery of the tree trunk 4, the arms 2 are provided with a hinge seat and hinged to the annular support 1 via the hinge seat, one of the arm ends of the arm 2 relative to the hinge seat is provided with a support plate facing the tree trunk, and the other arm end is connected to the telescopic strut 3. The supporting force of the telescopic strut 3 on the tree trunk is transmitted to the support plate through the lever action of the arm 2, and acts on the tree trunk through the support plate, thereby achieving reliable support for the tree trunk 4. The buried root fixing device includes a protective cage 7 for accommodating the soil ball wrapped around the roots of the transplanted tree, and a telescopic base 6 fixedly connected to the protective cage 7, the telescopic base 6 being provided with several telescopic bottom rods that extend telescopically outward from the protective cage; the protective cage 7 and the soil ball wrapped around the roots of the transplanted tree are inserted into the tree pit together, and the telescopic bottom rods on the telescopic base 6 are extended into the soil layer around the tree pit, connecting the tree roots to the telescopic base, thereby achieving reliable fixation of the tree roots.

[0066] The base 9 is set on the outer circumference of the tree planting location, and adopts a concrete base fixed to the building floor 92 of the aerial ecological courtyard. The base 9 can be cast integrally with the building floor 9, or prefabricated and spliced ​​to form a base separately and then anchored to the building floor 9 through anchors. The base 9 is a circular, triangular or polygonal ring seat structure that surrounds the tree trunk. The bottom ends of several telescopic struts 3 of the trunk support device are hinged and anchored to the base 9 along the circumferential direction of the trunk, and the other ends respectively form all-round support for the trunk from the circumferential direction. There are holes 901 distributed along the circumference of the bottom of the base 9. Some of the holes 901 serve as channels for drainage and ventilation of the tree roots, and the other holes corresponding to the telescopic bottom rod extension direction of the buried root device are used for the telescopic bottom rod to pass through and fix. The root system of the tree root is wrapped in a soil ball and planted in the base 9. The base 9 body can also be used as an outer flower bed for the tree.

[0067] The tree trunk supporting device and the underground root fixing device in this embodiment are described in detail below.

[0068] See also Figure 2 and Figure 3 The tree trunk support device uses a tree trunk 4 as the support body and includes an annular support 1, an arm 2, and telescopic struts 3. The annular support 1 is mounted around the periphery of the trunk 4. In the illustration, three sets of telescopic struts 3 are used as diagonal struts. These three sets of telescopic struts 3 are connected to the annular support 1 via the arm 2, forming a triangular support structure. In this embodiment, the telescopic struts 3 do not directly support and protect the tree trunk 4 through the annular support 1, but instead use the arm 2 as a lever to act on the trunk 4.

[0069] In practical applications, a single arm 2 installation method can be used to achieve diagonal support for the trunk of a tree, such as in this embodiment. Figure 4 and Figure 9 The support structure in the embodiment adopts three and four groups of arms 2 and telescopic struts 3 with the same installation method respectively. The number of diagonal struts of the telescopic struts can be selected according to the size of the tree. Figure 1 and Figure 4 As shown in , the trunk support function for large trees can be increased by extending a set of arms and a set of telescopic struts 3 from one side of the annular support 1 and fixing the support to the building wall 91 on one side of the aerial ecological courtyard.

[0070] Specific combination Figure 6 and Figure 7 The annular support 1 of this embodiment is an annular component that can be mounted on the outer circumference of the trunk 4, and is used for centrally installing the arm 2. A hinge seat 201 is provided on the main body of the arm 2. The arm 2 is hingedly mounted on the annular support 1 through the hinge seat 201, and the hinged structure of the arm 2 enables it to swing in the radial vertical plane of the annular support 1 with the hinge seat as the fulcrum. The arm 2 serves as a lever component for transmitting the supporting effect of the telescopic strut 3, with the hinge point of the hinge seat 201 as the fulcrum. One of the force arms relative to the hinge seat is provided with a support plate 202 facing the trunk 4, and the other force arm is connected to the telescopic strut 3. The hinge seat 201 in this embodiment is located in the middle position of the arm 2. The arm 2 is bounded by the hinge seat 201, and has two force arms on both sides. The force arm connecting the telescopic strut 3 is the power arm, and the force arm with the support plate 202 is the resistance arm. The supporting force provided by the telescopic strut 3 utilizes the leverage of the arm 2 and acts on the trunk 4 through the support plate 202, forming a supporting effect on the main trunk.

[0071] A triangular oblique support structure formed by three groups of arms 2 and telescopic struts 3 is installed on the periphery of the annular support 1. The support plates 202 of the three groups of arms 2 form a support ring 200 on the same side of the annular support 1. The support force of the three groups of telescopic struts 3 is clamped with the trunk 4 through the support ring 200 to achieve support and fixation around the trunk. The support plate 202 has an arc-shaped surface that matches the outer peripheral shape of the trunk 4. The entire support plate 202 is set to an oblique arc shape with a thick top and a thin bottom, that is, the upper radial radius is small and the lower arc radius is large, which adapts to the trend that the outer diameter of the trunk decreases with the height of the tree, meets the needs of supporting different diameters of the main trunk, has a clamping adjustment space, and is embedded with a flexible cushion layer on the inner side of the arc-shaped surface of the support plate 202 to reduce damage to the trunk skin during the support process.

[0072] Specific as Figure 6 As shown, the annular support 1 is a circular ring structure corresponding to the cross-section of the trunk 4. In order to facilitate the hoop of the annular support 1 on the trunk, the annular support 1 adopts two semicircular ring seats 101 to form a ring, and several groups of fixed shaft seats 102 for installing the arm 2 are evenly provided on the outer circumference of the annular support 1. The hinge seat 201 of the arm 2 is hinged to the fixed shaft seat 102 through the hinge shaft 11. The fixed shaft seat 102 has two parallel ear plates, and a coaxial through hole is provided on the ear plate. The hinge seat 201 of the arm 2 is provided with a hinge through hole. The hinge seat 201 of the arm 2 is inserted between the ear plates of the fixed shaft seat 102 and the hinge through hole is aligned with the through hole on the ear plate. Then the hinge shaft 11 is passed through the ear plate and hinge seat of the fixed shaft seat 102 to realize the hinged assembly of the two.

[0073] An even number of fixed shaft seats 102 are provided on the annular support 1. An ear plate for a fixed shaft seat is provided at each end of the outer edge of the semicircular ring seat 101 of the annular support 1. After the ring seats 101 are assembled into a ring, a complete fixed shaft seat is formed at the joint of the two ring seats 101. The hinge shafts 11 of the two fixed shaft seats connect and lock the ring seats 101 to form a complete annular support 1. This saves the structure of the annular support 1 and can also ensure that the fixed shaft seats 102 are evenly arranged on the annular support 1. The hinge shaft 11 adopts an anti-rotation setting, with a limiting flange provided at one end and a groove with a non-circular cross-section provided at the other end of the hinge shaft 11. An anti-loosening plate 111 is embedded in the groove. The anti-loosening plate 111 has two through holes. After the hinge shaft 11 is installed on the fixed shaft seat 102, the anti-loosening plate 111 is fixedly connected to the corresponding threaded hole on the fixed shaft seat by an internal hexagonal anti-loosening screw 112 to ensure that the hinge shaft does not rotate or loosen when the arm is subjected to rotational force.

[0074] The butted end faces of the ring seats 101 are provided with mortise and tenon structures 103 that engage with each other, i.e., concave and convex structures that engage with each other, so as to facilitate the quick and accurate butt connection between the ring seats 101 to form a ring and limit the radial movement of the ring seats 101 during the splicing process.

[0075] Specific as Figure 7 As shown, the arm in the figure has two installation postures on the annular support 1, one of which is the posture of the arm 2 in the figure, where the support plate 202 on the arm 2 is located on the lower side of the annular support 1. Figure 3 and Figure 4 The arm 2 in the embodiment adopts this posture to realize the support connection with the telescopic support rod 3. This installation method of the arm 2 applies a pulling force to the upward force arm of the arm 2 through the telescopic support rod 3. Through the lever action of the arm 2, the support plate 202 produces a support effect of pressing the tree trunk; another method is as follows Figure 7 In the middle position of arm 2', support plate 202 on arm 2 is located above annular support 1. This installation of arm 2' applies thrust to the downward force arm of arm 2 through telescopic support rod 3. Through the lever action of arm 2, support plate 202 exerts pressure on the tree trunk to support it. Both installation positions of arm 2 can achieve the desired support force transmission to the tree trunk by adjusting the corresponding action of telescopic support rod 3.

[0076] A plurality of groups of spare connection holes 203 are provided at the hinged joints between the arm 2 and the telescopic strut 3. During the actual installation and support process, the telescopic strut selects appropriate connection holes 203 to connect with the arm.

[0077] See also Figure 8 The telescopic strut 3 includes a threaded sleeve 31 and a screw rod 32 threadedly connected to both ends of the threaded sleeve 31. A connector is provided at the outer end of the screw rod 32 for fixing the telescopic strut 3 and connecting it to the arm 2. The threaded sleeve 31 has internal threads at both ends, and the spiral directions of the internal threads at both ends are set in opposite directions. The screw rod 32 is processed on the surface with external threads corresponding to the threaded sleeve 31. The threaded sleeve 31 and the screw rods 32 at both ends use threads in opposite directions. The screw rods 32 are used to connect the telescopic strut 3 to the outside world and do not rotate after connection. By rotating the threaded sleeve 31, the screw rods 32 at both ends are driven to move in opposite axial directions, realizing the telescopic adjustment of the telescopic strut 3.

[0078] The screw rod 32 is screwed with a locking nut 33. By rotating the locking nut 33 close to the threaded sleeve 31 and tightening it, the screw rod 32 and the threaded sleeve 31 can be locked. When the telescopic support rod 3 needs to be adjusted, the locking nut 33 on the screw rod 32 is first loosened and then the threaded sleeve 31 is rotated. After the support of the telescopic support rod 3 is adjusted into place, the locking nut 33 is rotated to lock the screw rod 32 and the threaded sleeve 31 to prevent the thread from loosening.

[0079] A boss is provided on the outer wall of the threaded sleeve 31, and a lifting ring 36 is provided on the outer wall of the threaded sleeve 31 by welding or threaded connection. By inserting a pry bar tool into the lifting ring 36, the threaded sleeve can be rotated to adjust the extension and retraction of the telescopic support rod. At the same time, the lifting ring 36 can also be used to fix the pull rope for auxiliary support of the tree trunk.

[0080] The outer end of the screw rod 32 is provided with a connecting piece for connecting the rods, and a fork structure is generally used to realize the quick connection of the rods. Figure 8 The ends of the screw rod 32 at both ends of the telescopic support rod 3 shown in the figure are respectively configured as a U-shaped fork 34 and a flat fork 35. The U-shaped fork 34 can be quickly connected to the appropriate connecting hole 203 at the end of the arm of the arm 2 through a pin, thereby realizing the rapid hinge connection of the telescopic support rod 3 and the arm 2. The flat fork 35 is quickly connected to the fixing member 5 with the U-shaped fork 34, and the fixing member 5 is anchored and fixed to the top of the base 9, thereby realizing the hinge fixation between the bottom of the telescopic support rod 3 and the base. The fixing member 5 can be a bolt fixing member with a U-shaped fork.

[0081] This embodiment can also adjust the fixed connection mode of the telescopic support rod 3 according to the on-site structure, and adopt two installation modes of the arm rods 2 and 2', such as Figure 5 、 Figure 10 、 Figure 11 and Figure 12 The support structure in the structure can support the trunk of the tree by forming a diagonal support structure through several groups of arms 2 and telescopic struts 3 with the same installation method, and can also reinforce the support effect of the individual diagonal support of the tree by adding arms 2' and telescopic struts 3 with other installation methods on the remaining fixed axle seats for pulling and guiding, so as to realize the connection support between the tree lateral and the building wall 91, the courtyard beam and slab columns, the support structure of the adjacent trees, or the main trunk of the tree itself and the support rod, and realize the integrated fixation of the network expansion of the tree group to jointly bear the transferred load and ensure the firmness and stability of the tree.

[0082] When this embodiment is used to fix a single tree, an independent support method is adopted. On the main trunk of the tree, two semi-annular ring seats 101 are combined through a mortise and tenon structure on the butt joint surface and a hinge axis to form a closed annular support 1, which is sleeved on the circumference of the main trunk of the tree; according to the size of the tree, an appropriate number of arms 2 are selected and evenly installed on the outer peripheral fixed shaft seats 102 of the annular support 1, and the support plates 200 of the arms 2 rotate around the hinge axes 11 on their respective fixed shaft seats 102 and fit with the main trunk; the connecting hole at the arm end of the arm 2 is hingedly connected to the U-shaped fork 34 of the telescopic support rod 3, and the flat fork 35 of the telescopic support rod 3 is hingedly fixed to the base fixing member 5 anchored on the base 9, so that the telescopic support rod is hingedly fixed to the base 9. By installing and deploying multiple telescopic struts 3 and adjusting their extension or contraction, the lever mechanism of arm 2 drives the support plates 200 to clamp against the main trunk from multiple directions, forming an independent support ring 200 of the annular support 1, providing all-around wind and rain-resistant traction support. The support device is constructed of high-strength materials and has an anti-corrosion surface treatment. For aesthetic reasons, it can be painted with an anti-corrosion paint that matches the tree's color.

[0083] See also Figure 13 and Figure 14 The underground root-fixing device anchors the roots of trees in the soil layer, and includes a telescopic base 6, a protective cage 7 and a connecting double nut 8. The protective cage 7 is used to accommodate the root-wrapped soil ball of the transplanted tree 4. The root-wrapped soil ball refers to the soil ball formed when the tree is attached to the root system of the tree during the transplanting process, so as to ensure that the tree forms a temporary protection for the plant root system during the transplanting process. The telescopic base 6 is fixed to the bottom of the protective cage 7 by connecting the double nut 8, and the root-wrapped soil ball of the transplanted tree 4 is wrapped and confined inside the protective cage 7. The entire underground root-fixing device is buried together with the root-wrapped soil ball of the transplanted tree in the transplanting tree pit, and the purpose of stabilizing and fixing the roots of the transplanted tree during its growth process is achieved through the underground root-fixing device.

[0084] See also Figure 14 、 Figure 15 and Figure 22 The telescopic base 6 of the underground root fixing device of this embodiment includes an upper support base 61, a telescopic bottom rod 62, a pointed shovel 63, a thrust plate 64, a limiting shaft sleeve 65, a locking screw 66, a lower support base 67 and a U-shaped double-headed screw 68. The underground root fixing device is inserted into the soil layer around the tree pit through a plurality of telescopic bottom rods 62 arranged on the telescopic base 6 and extending toward the outside of the enclosure, and passes through the through hole 901 provided at the bottom of the base 9, as shown. Figure 13 As shown in FIG, a set screw 93 is provided on the base 9 above the corresponding through hole 901 to press and fix the telescopic bottom rod 62 passing through the through hole 901 in the through hole, thereby anchoring the transplanted tree in the soil layer of the tree pit.

[0085] In this embodiment, the enclosure cage 7 is a cylindrical cage with an open bottom and only a trunk opening 701 at the top for the trunk of the tree 4 to pass through. The telescopic base 6 is a regular triangle frame inscribed on the circumference of the bottom of the enclosure cage 7. At the same time, a frame cavity for the sliding assembly of the telescopic bottom rod 62 is provided inside each side of the regular triangle frame. The telescopic bottom rod 62 retracts into the frame cavity of the telescopic base 6. Figure 22 As shown, the telescopic base 6 is located within the cross-sectional range of the enclosure cage 7, making it easy to place the telescopic base 6 into a tree pit corresponding to the size of the enclosure cage 7. The telescopic bottom rod 62 extends outward from one end of the inner cavity of the frame to form a support structure for the telescopic base 6 to extend outside the bottom circumference of the enclosure cage 7, and fix the buried root fixing device to the base 9, as shown in FIG. Figure 14 and Figure 15 As shown in the figure, the extended telescopic bottom rod 62 expands the supporting area of ​​the bottom of the enclosure cage 7. At the same time, the telescopic bottom rod 62 is inserted into the soil layer around the tree pit during the process of extending outward, thereby expanding the tensile resistance and anti-overturning stability of the underground device, and realizing the anchoring of the underground root fixing device in the tree pit.

[0086] To further enhance the support and anchoring reliability of the telescopic base 6, the telescopic base 6 in this embodiment comprises two layers of support bases that overlap or stagger themselves: an upper support base 61 and a lower support base 67. The upper and lower support bases 61 and 67 are identical regular triangle frames, overlapped and secured together by welding. Telescopic bottom rods 62 are telescopically mounted on each of the three side frames of the upper and lower support bases 61 and 67, resulting in a total of six telescopic bottom rods 62. Furthermore, two sets of telescopic bottom rods, located at the same corner of adjacent sides of the upper and lower support bases 61 and 67, are staggered along the directions of two adjacent sides. This ensures that the telescopic bottom rods 62 on the corresponding overlapping sides of the two support bases extend in two different directions. This ensures that the two telescopic bottom rods 62 at the same location extend in different directions, enhancing the overall stability of the telescopic base 6. By increasing the number of telescopic bottom rods 62 anchored in the soil, the anchoring effect of the telescopic base 6 on the entire buried root securing device is also enhanced.

[0087] In actual application, the size of the enclosure can be configured according to the size of the tree, and a corresponding number of telescopic bottom rods 62 can be configured by selecting a telescopic base with a quadrilateral or other polygonal frame. This embodiment will not be described in detail here.

[0088] The specific structures of the upper support base 61 and the lower support base 67 are described below.

[0089] See also Figure 15 、 Figure 16 and Figure 17 In the triangular frame of the upper support seat 61, a guide groove is opened on the top surface of each side frame along the side length direction. The telescopic bottom rod 62 on the upper support seat 61 is provided with a thrust plate 64 at the top. The telescopic bottom rod 62 is telescopically inserted into the inner cavity of the corresponding side frame of the upper support seat 61, and the thrust plate 64 thereon extends out from the guide groove, which can guide and limit the extension of the telescopic bottom rod 62, and by knocking the external force on the extended thrust plate 64, the end of the telescopic bottom rod 62 is inserted into the dense soil layer around the tree pit.

[0090] Further Figure 18a and Figure 18bAs shown, in order to limit the telescopic state of the telescopic bottom rod 62, a vertical limiting sleeve 65 is fixed at the tail end of the telescopic bottom rod 62 of the upper support seat 61. The inner hole of the limiting sleeve 65 is processed into a threaded hole. The limiting sleeve 65 is threadedly connected to insert a locking screw 66. The nut end of the locking screw 66 extends through the guide groove, and the cross-sectional width of the nut is larger than the guide groove. The locking screw 66 is unscrewed upward, and the telescopic bottom rod 62 can slide freely along the guide groove in the inner cavity of the side frame of the upper support seat 61. The locking screw 66 is tightened downward, and the telescopic bottom rod 62 is fixed to the upper support seat 61 by the locking screw and the limiting sleeve, maintaining the telescopic state and preventing free movement.

[0091] See also Figure 15 、 Figure 19 and Figure 20 The lower support seat 67 overlaps with the upper support seat 61 and is located in the lower layer. The top of the lower support seat 67 is covered and shielded by the lower support seat 67. In the triangular frame of the lower support seat 67, guide grooves are respectively provided on the side surfaces of both sides of each side frame along the side length direction. The telescopic bottom rod 62 on the lower support seat 67 is provided with thrust plates 64 on both sides. The telescopic bottom rod 62 is telescopically inserted into the inner cavity of the corresponding side frame of the lower support seat 67, and the thrust plates 64 on both sides extend from the guide grooves, which can guide and limit the extension of the telescopic bottom rod 62, and by knocking external force on the extended thrust plate 64, the end of the telescopic bottom rod 62 is inserted into the dense soil layer around the tree pit.

[0092] Further Figure 21a and Figure 21b As shown, since the top of the lower support seat 67 is shielded by the upper support seat 61, in order to limit the telescopic state of the telescopic bottom rod 62, a horizontal limiting sleeve 65 is fixed at the tail end of the telescopic bottom rod 62 of the lower support seat 67. The inner hole of the limiting sleeve 65 is processed into a threaded hole, and the two ends of the limiting sleeve 65 are respectively threaded to insert locking screws 66. The nut end of the locking screw 66 extends from the side through the guide groove, and the cross-sectional width of the nut is larger than the guide groove. When the locking screw 66 is unscrewed outward, the telescopic bottom rod 62 can slide freely along the guide groove in the inner cavity of the side frame of the lower support seat 67. When the locking screw 66 is tightened inward, the telescopic bottom rod 62 is fixed to the lower support seat 67 by the locking screw and the limiting sleeve, and the telescopic state is maintained and cannot move freely.

[0093] like Figure 23a and Figure 23bAs shown in , this embodiment can also stagger the upper and lower support seats of the telescopic base, that is, the three side edges of the upper support seat and the lower support seat are staggered, so that the thrust plates 64 corresponding to the side edges of each support seat can be set on the top of the telescopic bottom rod, and all thrust plates 64 can be extended from the top guide groove of the support seat, which is more convenient to operate external force to push the thrust plates and the telescopic bottom rod.

[0094] like Figure 15 and Figure 22 As shown in the figure, whether it is the telescopic bottom rod 62 on the upper support seat 61 or the lower support seat 67, a pointed shovel 63 is welded at the extended outer end. The pointed shovel 63 is a pointed triangle or arrow arc, which reduces the resistance of the telescopic bottom rod 62 to the insertion of the soil layer, making it more labor-saving when the telescopic bottom rod 62 is inserted into the soil layer.

[0095] The telescopic base 6 is inscribed in the circumference of the bottom of the protective cage 7. A U-shaped double-headed screw 68 with the screw head facing upward is set at the corner point where the telescopic base 6 and the bottom circumference of the protective cage 7 meet. A screw hole for the screw head of the U-shaped double-headed screw 68 to dock and pass through is set at the corresponding position on the bottom of the protective cage 7. Then, the double nut 8 is screwed onto the U-shaped double-headed screw 68 to fix the telescopic base 6 and the protective cage 7 in connection.

[0096] like Figure 24 and Figure 25 As shown, the cage 7 is assembled from several cage segments 71, which are cut along the vertical diameter of the cage 7. This assembled cage allows for quicker installation around the root ball. Connecting ribs are provided at the bottom of the cage and along the sides of the segments 71 where they meet. The bottom ribs are used to securely connect to the telescopic base 6, while the side ribs allow for joint connection.

[0097] See also Figure 26a 、 Figure 26b and Figure 26c The cage pieces 71 are provided with slots 711 and ridges 712 that fit together on the joint surface, facilitating quick splicing and positioning of the cage pieces 12. Specifically, the arc-shaped hollowing of the cage piece 71 is evenly distributed with connecting ribs for docking and positioning along the axial and radial directions. The connection between the top and side of the arc-shaped hollow bracket of the cage piece 71 is designed with a long slot on one side and a long ridge on the other side. During assembly and installation, the long slots of adjacent cage pieces and the long ridges of adjacent cage pieces are embedded in each other, and a circular arc sleeve is designed in the radial direction. When the cage pieces 71 are spliced ​​together to form a cage, a trunk opening 701 is formed at the top of the cage, which can reliably wrap the soil ball and fix the main root, effectively preventing soil loss caused by rainwater intrusion.

[0098] The splicing position of the enclosure piece 71 coincides with the connection area between the enclosure cage 7 and the telescopic base 6. A screw hole 713 is set at each end of the connecting rib plate at the bottom of the enclosure piece 71. The U-shaped double-headed screw 68 on the telescopic base 6 passes through the screw holes 713 on the connecting rib plate at the bottom of the two adjacent spliced ​​enclosure pieces at the same time, so as to fix the telescopic base 6 to the bottom of the enclosure cage 7 while splicing and fixing the enclosure pieces 71. The assembled enclosure cage 7 can also be directly anchored to the building floor 92 at the bottom of the soil layer through anchor bolts, and further increase the stability of the tree roots to the building floor of the aerial ecological courtyard through the underground root fixing device. The enclosure piece 71 is reserved at the same position at the top with a screw hole 713 for connecting and installing tree pit covers, ornamental lamps, other supports, etc.

[0099] The enclosure 7 is constructed of hollow profiles with a tubular cavity, which can be made of a certain wall thickness. The tubular cavity is connected to an irrigation system that circulates water and nutrient solution at the temperature required for tree root growth. The internal tubular cavity is connected to a precise drip irrigation system through the annular pipe of the enclosure near the soil-covered root system, effectively increasing the utilization rate of water and nutrient solution and improving soil permeability for the roots.

[0100] According to the needs of the use environment, circulating water or nutrient solution with suitable temperature is passed through the cavity of the enclosure cage in winter, and circulating cold water or nutrient solution is passed through in summer to control the temperature of the soil near the root system to keep it warm in winter and cool in summer.

[0101] In this embodiment, both the enclosure cage 7 and the telescopic base 6 are made of corrosion-resistant metal materials. Specifically, the hollowed-out enclosure segments 71 are welded from flat steel or corrosion-resistant steel sections, or integrally cast. The connecting nut 3 and locking screw 16 are made from corrosion-resistant materials such as stainless steel. The telescopic base 6 and telescopic bottom rod 62 are welded from section steel or steel plates, and the surface is treated with an anti-corrosion treatment, thereby enhancing the strength and service life of the buried root anchor.

[0102] The underground root fixing installation method using the underground root fixing device of this embodiment includes the following steps:

[0103] The first step is to place the telescopic base 6 at the bottom of the tree pit with the telescopic bottom rod 62 in the retracted state. Then, the telescopic bottom rod 62 is extended outward from the telescopic base 6 and inserted into the soil layer around the tree pit and locked. This increases the pull-out resistance and anti-overturning stability of the underground device, and anchors the telescopic base 6 to the bottom of the tree pit.

[0104] The second step is to hoist the transplanted tree and place the root ball of the transplanted tree in the center of the telescopic base. Keep the tree in a vertical position during the hoisting and transplanting process.

[0105] The third step is to assemble the enclosure pieces 71 of the enclosure cage 7 close to the roots of the transplanted tree and wrap the soil ball. After assembling the complete enclosure cage 1, the enclosure cage 7 is fixedly connected to the double-headed screw on the telescopic base 6 by connecting the double nuts 8. The enclosure cage 7 and the telescopic base 6 will wrap and fix the roots of the transplanted tree 360° three-dimensionally;

[0106] Step 4: Cover the tree pit with soil and compact it.

[0107] The actual operation process is as follows: first, place the telescopic base 6 at the bottom of a circular tree pit with a deep cover or firmly connect it to the bottom cast embedded parts; then, use a pneumatic pickaxe, electric pickaxe, or hammer to strike the thrust plates 64 on each telescopic bottom rod 62 in the direction of the side length of the telescopic base's regular triangle frame. The telescopic bottom rods 62 on the two layers of support seats extend in opposite directions in turn, evenly insert into the dense soil layer around the tree pit or firmly connect to the bottom cast embedded parts. After the telescopic bottom rod 62 is in place, the end is fixed with a locking screw. The root ball of the transplanted tree is then filled with soil to form a spherical arc-shaped seat corresponding to the size of the protective cage. The tree is then hoisted and placed on the regular triangle frame of the telescopic base 6, keeping the tree in an upright position. In addition to the initial fixation of the soil ball with the telescopic base, the main fixation is the protective cage 7, which is a cylindrical cage with three hollow cage pieces 71, whose inner arcs and inner top surfaces are close to the soil ball. The bottom is fixed to the U-shaped stud screw of the telescopic base 6 with double connecting nuts 8. The telescopic base 6, protective cage 7, and double connecting nuts 8 together enclose the main body of the root ball of the transplanted tree, forming a 360-degree fully enclosed fixed protective cage, which compacts the soil in the tree pit and realizes the underground root-fixing planting of large trees. This method adopts segmented construction and assembly. As the tree roots grow and elongate, they can be embedded with the hollow enclosure cage to form a stable and firm root foundation. The telescopic base 6 has two-way extended telescopic bottom rods embedded in the dense soil layer around the tree pit and extended to six directions to ensure that the telescopic base can reach the maximum range, expanding the soil coverage nearly 6 times that of the original tree pit, greatly expanding the tensile resistance and anti-overturning stability of the underground device, ensuring that the telescopic base provides the maximum support range for transplanted trees. The tree roots are connected to the telescopic base to achieve long-term stability and firmness around the tree roots and soil ball.

[0108] Example 2

[0109] Example 1 discloses an independent fixing method for a single tree. The number of telescopic support rods and diagonal braces set for each tree can be selected according to the size of the tree. The telescopic support rods are fixedly connected to the building floor, base, embedded parts, planting boxes, adjacent walls, courtyard beams and slabs, columns, etc. The tree support force can be strengthened or loosened by adjusting the telescopic action of the telescopic support rods.

[0110] This embodiment is aimed at providing integrated support for a plurality of trees planted in an aerial ecological courtyard of an ecological building through a tree group network, and generally adopts a support device with a six-group or eight-group arm structure.

[0111] See also Figure 27 and Figure 28 Taking two trees as an example, each tree is provided with a corresponding base, and the roots of each tree are fixed by an independent underground root-fixing device. This embodiment does not describe the underground root-fixing device in detail. In addition to the independent trunk support device described in Example 1, the annular supports of two adjacent trees are interconnected by assembling arm rods 2 and telescopic struts 3 or steel cables, connecting the support structures of all trees into an integrated mesh support system. The entire support system provides traction support for all trees, further improving the combined support effect of the tree group.

[0112] In practical applications, a single arm 2 installation method can be used to achieve diagonal support for the trunk of a tree, such as in this embodiment. Figure 3 and Figure 9 The support structure in the tree is made of three or four sets of arms 2 and telescopic struts 3 with the same installation method. The number of diagonal braces of the telescopic struts can be selected according to the size of the tree. The fixed connection method of the telescopic struts 3 can also be adjusted according to the on-site structure. Two installation methods of arms 2 and 2' are used, such as Figure 4 、 Figure 5 、 Figure 10 、 Figure 11 and Figure 12 The supporting structure in the invention can support the trunk of a tree by forming a diagonal support structure through several groups of arms 2 and telescopic struts 3 installed in the same manner, and can also reinforce the supporting effect of a single diagonal support of the tree by adding arms 2' and telescopic struts 3 installed in another manner on the remaining fixed axle seats for pulling and guiding.

[0113] In the independent support mode for each tree, all arms adopt the same posture (such as Figure 12 The arm 2' in the installation posture) is matched with the telescopic support rod to connect the adjacent trees to realize the arm of the networked support. The arm adopts the same posture as the arm of the independent support method (such as Figure 12 The arm 2' in the installation posture) or the reverse posture (such as Figure 12 The arm 2 in the installation posture is connected to the telescopic support rod, and the tree supporting force is strengthened or loosened by adjusting the telescopic action of the telescopic support rod.

[0114] The tree support method of the present invention can be applied to different planting environments. When conditions permit, it does not occupy underground and lower support space. The support device can also be installed individually or multiple times on the main trunk of a single tree to achieve connection and support between the tree's side and the wall, courtyard beams and columns, supporting structures of neighboring trees, or the tree's own main trunk and support poles, and realize the integrated fixation of the network expansion of tree groups, jointly bear the transferred load, and ensure the firmness and stability of the trees.

[0115] See also Figure 29 The support device with six sets of arm structures is used for multiple trees planted and arranged in the ecological courtyard. After each tree is independently supported, the fixed axis seats of all trees are pulled and guided into an integrated mesh support group by adding installation arms 2' and telescopic struts 3, so that the support structures of all trees are connected into a network, thereby improving the overall support effect of all trees.

[0116] In practical applications, the adjustable support mode and support method of the present invention can also be used for supporting and protecting various columns or other vertical pole structures that need to maintain a stable upright state.

[0117] The above are only specific embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
