Technical Field
[0001] This utility model relates to the technical field of ancient tree reinforcement devices, and in particular to hard and soft devices for reinforcing and supporting ancient and famous trees. Background Technology
[0002] Ancient and famous trees, as precious legacies left by nature and our ancestors, carry significant ecological, historical, and cultural value. However, they face numerous threats during their growth. On the one hand, the increasing age of ancient trees weakens their structure, making them prone to tilting, branch overloading, or breakage. On the other hand, geological disasters (such as landslides and mudslides) and extreme weather (typhoons and snowstorms) can also severely damage ancient trees, causing them to tilt, fall, or break. Therefore, it is crucial to take reinforcement and support measures for ancient trees exhibiting these conditions to protect these precious resources.
[0003] Currently, various technologies and devices exist in the field of ancient tree reinforcement and support. Common methods include traditional wooden pole supports and steel pipe supports, which involve fixing one end of the support to the ground and the other end against a leaning part of the ancient tree or a heavy-load branch to distribute the pressure on the tree. However, these devices have significant drawbacks. Their fixed structure makes it difficult to adjust flexibly according to different seasons, such as the heavy canopy in summer when branches are lush and the lighter canopy in winter when leaves have fallen, resulting in poor support effectiveness. Other methods use steel cable tensioning, connecting the ancient tree to surrounding fixed points and using tension to stabilize the tree. However, this method easily causes abrasion to the bark of the ancient tree, affecting its growth. Furthermore, the tension of the steel cable is difficult to maintain stably over long-term use, posing a safety hazard.
[0004] As people increasingly value the protection of ancient trees, higher demands are being placed on the safety, applicability, and environmental friendliness of ancient tree reinforcement and support devices. Existing reinforcement and support technologies and devices are no longer sufficient to meet practical needs, necessitating the development of a new type of ancient tree reinforcement and support device to address the problems of existing technologies and better achieve effective protection of ancient trees. Utility Model Content
[0005] This utility model proposes a hard and soft device for reinforcing and supporting ancient and famous trees in order to solve the above-mentioned problems.
[0006] The technical solution of this utility model is implemented as follows:
[0007] The reinforcement and support system for ancient and famous trees includes a rigid support device for supporting the tree trunk and branches, and a soft traction device for traction and fixation of the branches. The rigid support device includes a fixed clamp and a movable clamp that are bolted to the tree trunk or branches. The inner walls of the fixed clamp and the movable clamp are provided with a first protective pad that contacts the tree trunk. The fixed clamp is fixed to one end of the main support rod, and an upper fixing plate is fixed to the other end of the main support rod. The upper fixing plate is detachably connected to the telescopic end of a jack. The base of the jack is fixed to a pre-embedded base, which is made of concrete poured on the ground around the tree. The soft traction device includes two traction sleeves, which are respectively installed on two branches and connected together by an adjustable tensioner.
[0008] Furthermore, the width of the first protective pad is greater than the width of the fixed clamp and the movable clamp.
[0009] Furthermore, the jack is provided with a protective box fixed on the pre-embedded base. The upper surface of the protective box is formed with a through hole to facilitate the passage of the telescopic shaft of the jack. The protective box has an opening on one side, and a door is hinged to the opening of the protective box. The movable end of the door is installed together with the protective box by a lock.
[0010] Furthermore, the adjustable rope tensioner includes a main body, with an internal threaded sleeve fixed at each end of the main body. A screw is installed inside the internal threaded sleeve via a threaded connection, and a rope fixing device is formed at the outer end of the screw.
[0011] Furthermore, the rope securing device is ring-shaped or hook-shaped.
[0012] Furthermore, the traction sleeve includes an outer fixing plate, and a second protective pad is provided on the side of the outer fixing plate that contacts the branch. Several fixing buckles are fixed on the outer wall of the outer fixing plate along the length direction. The wire rope passes through the fixing buckles and is hooked onto the adjustable rope tensioner. The ends of the wire rope are fixed together by locking buckles to form a closed loop.
[0013] Furthermore, the width of the second protective pad is greater than the width of the outer fixing plate.
[0014] Furthermore, the adjustable rope tensioner is covered with a sun-protective and rain-proof cover.
[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0016] 1. The rigid support device and the soft traction device can be prefabricated and assembled on site using bolts, thus eliminating the safety hazards of high-altitude welding.
[0017] 2. Using jack support technology allows for adjustment of the length of the rigid support device and the support force according to the season. This makes it easy to lower the jacks in winter to allow the branches to relax and extend, and raise the jacks in summer to provide strong support and prevent the branches from breaking.
[0018] 3. The upper fixing plate and the jack are detachably connected, making it easy to disassemble when the main support rod needs to be replaced after years of rust and corrosion.
[0019] 4. The tension can be adjusted according to the stress on the branches and trunk, changing the traditional method of tightening the rope and avoiding the branches rebounding after the rope is loosened, which would cause the traction to be inadequate.
[0020] 5. Rigid support devices and soft traction devices can be installed at multiple points on the same tree, greatly reducing construction costs and risks. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figures 1-5As shown, the reinforcement and support system for ancient and famous trees includes a rigid support device 1 for supporting the tree trunk and branches, and a flexible traction device 2 for traction and fixation of the branches. The rigid support device 1 includes a fixed clamp 105 and a movable clamp 106 that are fixed to the tree trunk or branches with bolts. The fixed clamp 105 and the movable clamp 106 are made of steel plates with a thickness of not less than 3mm by bending and rolling. The fixed clamp 105 and the movable clamp 106 have fixing holes with a diameter of 14mm at corresponding positions at both ends to facilitate the installation of bolts. The inner walls of the fixed clamp 105 and the movable clamp 106 are provided with a first protective pad 107 that contacts the tree. The first protective pad 107 is made of rubber and its length is preferably enough to wrap around the branch or trunk. The fixed clamp 105 is welded to one end of the main support pole 104. The other end of the main support pole 104 is welded with a 5mm thick steel square upper fixing plate 103 with a side length of 200mm. The main support pole 104 is made of a 60mm diameter hot-dip galvanized pipe. The center of the upper fixing plate 103 is aligned with the lifting jack 102. With the shaft centers aligned, the upper fixing plate 103 is detachably fixed to the telescopic end of the jack 102. The jack 102 is a 3-5 ton hydraulic vertical jack. The base of the jack 102 is welded to the pre-embedded base 101. The pre-embedded base 101 is made of concrete poured on the ground around the tree. The pre-embedded base 101 includes a panel and reinforcing steel bars. 5-8mm steel plates are selected and cut into 350mm long squares. Four 30cm long, 20mm diameter threaded steel bars are welded to one side of the steel plate. The four threaded steel bars are welded and fixed diagonally in the middle with 16mm threaded rods to form the skeleton of the pre-embedded base 101. After pouring concrete, the pre-embedded base 101 is formed. The soft traction device 2 includes two traction sleeves 22, which are installed on two branches respectively. The two traction sleeves 22 are connected together by an adjustable rope tensioner 21. After the processing of the parts in the hard support device 1 and the soft traction device 2 is completed, they are coated with anti-rust paint at least twice to prevent rust and extend their service life.
[0032] In this embodiment, the width of the first protective pad 107 is greater than the width of the fixed clamp 105 and the movable clamp 106.
[0033] In this embodiment, to prevent the jack 102 from being loosened after the support is installed, a stainless steel protective box 108 is fixed on the pre-embedded base 101 on the outside of the jack 102. A through hole is formed on the upper surface of the protective box 108 to facilitate the passage of the telescopic shaft of the jack 102. After the telescopic shaft of the jack 102 passes through the through hole, it is fixed together with the main support rod 104. The protective box 108 has an opening on one side corresponding to the lifting and lowering operation handle of the jack 102. A door 109 is hinged at the opening of the protective box 108. The movable end of the door 109 is fixed with a latch and is installed together with the protective box 108 through a lock 110 to facilitate the adjustment by maintenance personnel.
[0034] In this embodiment, the adjustable rope tensioner 21 includes a main body 211, with an internal threaded sleeve 212 fixed at each end of the main body 211. A screw 213 is installed inside the internal threaded sleeve 212 through a threaded connection, and a rope fixing device 214 is formed at the outer end of the screw 213.
[0035] In this embodiment, the rope securing device 214 is ring-shaped or hook-shaped.
[0036] In this embodiment, the traction sleeve 22 includes an outer fixing plate 221. The outer fixing plate 221 is made of 3mm thick hot-dip galvanized sheet, cut into 80mm wide and 80-200cm long pieces. The cut edges are polished smooth and then bent into an arc shape. A second protective pad 225 is provided on the side of the outer fixing plate 221 that contacts the branch. Several fixing buckles 222 are welded along the length of the outer wall of the outer fixing plate 221. The fixing buckles 222 can be nuts with an inner diameter of 25mm. Welded every 20cm along the centerline of the surface, the wire rope 223 passes through the fixing buckle 222 and is hooked onto the adjustable rope tensioner 21. The ends of the wire rope 223 are fixed together by the locking buckle 224 to form a closed loop. The wire rope 223 is soaked in waste machine oil and then dried before use. The diameter of the wire rope 223 is 6mm-20mm, which is selected according to the thickness of the tree trunk and the weight of the branches being pulled. The thicker the branches being pulled, the thicker the wire rope used. The locking buckle 224 is a national standard wire rope clip.
[0037] In this embodiment, the second protective pad 225 is a rubber sheet with a thickness of 3-5mm, a width of 100mm, and a length that is the same as or shorter than that of the outer fixing plate 221. It is required to cover the contact area between the outer fixing plate 221 and the tree branch, and the width of the second protective pad 225 is greater than the width of the outer fixing plate 221.
[0038] In this embodiment, in order to extend the service life, the adjustable rope tensioner 21 is wrapped with a sun and rain cover. The adjustable rope tensioner 21 is first wrapped with a non-woven cotton cloth to form a base layer, and then wrapped with a rainproof cloth to form a sun and rain cover.
[0039] like Figure 6As shown, during support, first weld the prepared fixing clamp 105 to the top of the support main pole 104, then lift the support and place the top fixing clamp 105 on the support point on the tree. Use the prepared rubber pad (first protective pad 107) between the fixing clamp 105 and the bark to prevent damage to the tree. Then connect the movable clamp 106 to the fixing clamp 105 with a screw. When connecting, check the upper and lower rubber pads to ensure they are fully in place, then tighten the nuts. Next, place the lower part of the support main pole 104 on the upper fixing plate 103 above the pre-embedded jack lifting shaft (the pre-embedded base 101 must be poured with cement concrete 1-2 days in advance), and then weld it firmly. Use the lever to slowly apply force to the jack 102 until the tree is completely reset and the support main pole 104 is fully under force. Then, the jack 102 below the main support rod 104 is encapsulated and welded with the cut stainless steel plate to form a protective box 108. A lock 110 is installed on the door 109 of the protective box 108 to prevent it from being damaged by human intervention and causing unforeseen losses.
[0040] Select the branch above the tree that needs reinforcement and traction, determine the point of force, and place the prepared outer fixing plate 221 on the point of force. Then, thread the steel wire rope 223 into the nut (fixing buckle 222) on the outer fixing plate 221, and securely connect the two ends of the steel wire rope 223 with national standard clips. Place a rubber sheet (second protective pad 225) between the outer fixing plate 221 and the tree trunk, being careful not to damage the bark. Select a suitable tree trunk to bear the load and determine the point of force. Assemble the outer fixing plate 221 and steel wire rope 223 in the same way. The length of the steel wire rope 223 is determined according to the distance between the point of force and the point of traction. Install an adjustable rope tensioner 21 with the same breaking force unit as the steel wire rope 223 at the midpoint between the two points, and then slowly adjust the rope tensioner until the force is fully applied.
[0041] When reinforcing a tree, the number of rigid support devices 1 and soft traction devices 2 can be selected according to the tree's condition. All pre-processed parts can be prepared in advance to avoid welding at high altitudes (on the tree) and causing fires.
[0042] Components not described in detail in this article are existing technologies.
