Structure is maintained in building foundation afforestation

Technical Field

The application relates to the field of building greening, in particular to a structure is maintained in building foundation greening.

Background

At present, indexes such as greening and environmental protection are more and more emphasized in various projects, and the indexes are particularly applied to the building construction process, and during the construction process, all links need to be subjected to dust fall, dust removal, cleaning and the like, so that the influence on the surrounding environment in the construction process of a construction site is reduced to the minimum. Green plants are planted around some construction projects, and since the root system of a newly transplanted tree does not grow, the tree is prone to lodging under wind.

In view of this, the trees need to be supported to avoid being blown down by the wind. The existing tree supporting structure is usually reinforced by a tree support method or fixed by steel pipes with nails. The support of these devices is not stable. In addition, some tree fixing devices are available in the market, but the tree fixing devices generally have the problems of complex structure, inconvenience in operation and the like, so that the operation time is increased.

Disclosure of Invention

The application provides a building foundation afforestation maintenance structure to improve above-mentioned problem.

The invention is particularly such that:

a building foundation greening maintenance structure, comprising:

a ferrule having an annular aperture defined by an annular wall for a tree to nest within;

the support column is composed of a front section, a middle section and a rear section, is of a hollow tubular structure, and is positioned at the other end of the support column at the rear section for being directly or indirectly fixed on the ground;

the plurality of thrust plates are fixed inside the rear section at intervals along the axial direction of the support column, and a first distance D2 between every two adjacent thrust plates is gradually increased along the direction from the front section to the rear section; the compression strength of each thrust plate is gradually increased along the direction from the front section to the rear section;

the anti-pulling plates are fixed inside the front section at intervals along the axial direction of the supporting column, each anti-pulling plate is provided with through holes distributed along the axial direction of the supporting column, and a second distance D between every two adjacent anti-pulling plates is gradually reduced along the direction from the rear section to the front section; along the direction from the rear section to the front section, the compressive strength of each anti-pulling plate is gradually increased; the diameter of the through hole of each anti-pulling plate is gradually reduced along the direction from the rear section to the front section;

an elastic plate arranged along the section of the middle section; and

the movable rod penetrates through the through holes of all the anti-pulling plates and is sleeved in the supporting column, one end of the movable rod is connected to the elastic plate, the other end of the movable rod extends out of the supporting column and is connected with the hoop, and the diameter of the movable rod is gradually reduced from one end to the other end.

The greening maintenance structure for the building foundation pit has the advantages of compact structure, small occupied space and convenience in storage, storage and transportation. The body is made up of a support post and ferrule, with the other major components "hidden" within the support post. Therefore, it is simple in appearance. In addition, the parts do not need to be assembled and matched when in use, so the operation difficulty can be reduced.

In addition, more importantly, the tree supporting effect of the building foundation pit greening maintenance structure is good, and the wind-proof lodging-resistant effect of trees can be effectively improved.

Specifically, the support column thereof, and the thrust plate, the tension preventing plate and the elastic plate therein are engaged with the movable column. Controlled and limited stretching of the movable column is controlled, shaking movement of trees when blown by wind can be responded, trees cannot fall down, and the risk that the trees are easily broken due to the fact that an existing tree supporting device can be avoided.

Optionally, the length of the front section in the axial direction of the support column is smaller than the length of the rear section in the axial direction of the support column, and the center of gravity is at the rear section.

The design of doing so to the length of the anterior segment of support column and back end can move its focus to the back end of support column to avoid because its building foundation afforestation maintains the gravity extrusion to trees of structure. This can be of positive significance when the tree to be supported is relatively young. For taller trees, longer support columns are typically required, with correspondingly greater gravitational forces. In this case, the gravity center of the mobile phone is moved backwards, so that the mobile phone can be used in an erected mode conveniently; of course, the structure can be prevented from being easily turned over by trees in case of strong wind.

Optionally, the structure is maintained in building foundation afforestation still includes the base with the support column complex, and the other end of support column is fixed in ground indirectly through the base.

Compare in directly inserting the support column at the bottom of the ground or supporting on ground, the base can provide more stable supporting role to the support column, avoids the support column to remove easily to also can improve the effect of strutting to trees.

The base provided with the independent threaded hole is convenient for fixing the support column and is also convenient for carrying out necessary replacement. Meanwhile, the movable part of the supporting column can rotate, so that the supporting column can be allowed to generate certain twisting motion, and the damage to other parts in the structure can be avoided.

Alternatively, the base has a body having a recess and a movable block hinged in the recess by a pivot provided with a torsion spring to allow the movable block to swing centering on the pivot, and a screw hole is provided in the movable block.

Because the screw hole is set up through the movable block that can rotate, consequently, when the support column is connected in this movable part, the support column is whole also can rock. Therefore, the support column can shake to some extent along with the trees blown by the wind, so that the restriction on the trees can be relieved to some extent. I.e., within limits to allow the tree to rock relatively freely, so that rocking of the tree in these circumstances does not cause it to fall over or cause the root system to lift, and so there is no need or great need to limit it. That is, supporting a tree is not a complete limitation of the tree's activities.

Optionally, the body has a pointed cone.

The pointed cone facilitates the base to be embedded in the bottom surface.

Optionally, the structure is maintained in building foundation ditch afforestation still includes along the annular wall a plurality of elastic support body of annular overall arrangement, and elastic support body includes spring and contact plate, and the both ends of spring are connected with annular wall and contact plate respectively, and the flexible direction of every spring is along the radial distribution of annular hole.

The resilient support allows the ferrule to have holes that can be adjusted as needed to facilitate securement to trees of different tree diameters without the need for multiple sets of devices for different tree diameters. I.e. its flexibility of use is higher. Moreover, the device structure can firmly fix trees with different tree diameters through the hoop and can perform adaptive movement to a certain degree when the trees shake due to wind.

Optionally, the contact plate has an arc shape and is used for facing the arc concave surface of the tree sleeved in the annular hole.

The arc-shaped concave surface has more potential contact positions and larger contact area with the tree, and therefore, more favorable support can be provided.

Optionally, the arc-shaped concave surface has the spurs arranged in an array.

In order to prevent the newly transplanted tree from lodging, the tree needs to be supported. One basic requirement for supporting trees is that the tree support device can support trees well.

However, the tree fixing device on the market at present has a very simple structure, but the effect is very original, namely the supporting effect is not good. Or, other devices have a very complicated structure, so that the use of the device is very inconvenient, and the occupied space is large, so that the planting of trees is inconvenient.

In view of the above, the inventor of the present invention proposes a novel architecture for maintaining the greening of the foundation pit, and the structure thereof refers to fig. 1 to 9. The greening maintenance structure for the building foundation pit is simple in structure, convenient to use and good in supporting effect on trees.

The building foundation greening maintenance structure comprises the hoop shown in figure 1, the supporting column shown in figure 4, a plurality of thrust plates, a plurality of anti-pulling plates, an elastic plate and a movable rod, and refer to figures 8 and 9.

The main body of the building foundation pit greening maintenance structure is a support column. A plurality of thrust plates, a plurality of anti-pulling plates and an elastic plate are all arranged in the supporting column. The movable rod partially extends into the movable rod and partially extends out of the movable rod. And the end that protrudes beyond the movable rod is connected to a ferrule. Wherein, the hoop is sleeved on the tree to limit and restrict the tree. The support post is inserted into or secured to the ground through one end. Therefore, the tree can be transmitted to the hoop by shaking greatly, and then transmitted to the support column. The greening maintenance structure for the building foundation pit plays a good tree supporting effect through the buffered movement of the movable rod relative to the support column.

Wherein the ferrule has an annular bore defined by an annular wall. The annular hole is used for being sleeved with a tree. The ferrule can be of a unitary or split construction. The split structure can be divided into two parts. For example, in some embodiments, the ferrule 100 has a ring portion 101 and a straight rod portion 102, and the ring portion 101 and the straight rod portion 102 are integrally formed, as shown in fig. 1. The annular portion 101 therein has an annular aperture 103, and the annular aperture 103 is defined by an annular wall 104. The annular hole 103 may be a circular hole, or may be a hole having another shape, such as a hexagonal cross section, or may have another shape. Further, the building foundation greening maintenance structure can also comprise a fixing hoop. The fixing hoop is used for being sleeved on a trunk and has similar functions with the hoop. The fixing band and the hoop are connected with each other by a rigid connecting rod, so that the two move synchronously. The axial direction of the fixed hoop is collinear with the axial direction of the annular hole of the hoop, and the fixed hoop is positioned at one end close to the support column in the direction from the other end of the support column to one end of the support column.

Preferably, the architecture foundation greening maintenance structure may further include a plurality of elastic supports 105 (6 in fig. 2) arranged in a ring shape along the annular wall. The elastic support body is used for enabling the annular hole to have a self-adaptive hole diameter so as to reinforce trees with different tree diameters. In one case, the elastic support may be a spring or other material with elastic properties. In the present invention, the elastic support 105 includes two parts, which are a spring 1051 and a contact plate 1052. Also, both ends of the springs 1051 are connected to the annular wall 104 and the contact plate 1052, respectively, and the expansion and contraction direction of each spring 1051 is distributed in the radial direction of the annular hole. The contact plate can be a rectangular plate or a cylinder. The contact plate may also be arcuate and have an arcuate concave surface adapted to face a tree nested within the annular aperture. In one example, the contact plate 1052 may include a flat surface 10521 and an arcuate surface 10522, see fig. 3. The spring 1051 is connected to the flat surface 10521 of the contact plate 1052. As a further modified example, the curved concave surface as the curved surface 10522 has the spurs (not shown) arranged in an array. The spikes may be arranged in an array or they may be arranged sporadically.

The ferrule can be connected to the end of the movable rod through a hole (not shown) in the straight rod portion 102, wherein the connection can be a threaded connection, a snap connection, a buckle connection, a welding connection, or the like.

The support column 200 is integrally composed of a front section 201, a middle section 202 and a rear section 203, and two ends of the middle section 202 are respectively connected with the front section 201 and the rear section 203; as shown in fig. 4. In one example, the front section has a length in the axial direction of the support column that is less than the length of the rear section in the axial direction of the support column, and the center of gravity is at the rear section. This can be achieved by selecting the material of the front and rear sections or by specifically controlling the wall thickness thereof.

Integrally, the front section, the middle section and the rear section are integrally formed. And the support column is a hollow tubular structure. And, one end of the support column located at the front section is a free end. And the other end of the support post at the rear section is adapted to be directly or indirectly fixed to the ground. As mentioned above, the other end may be fixedly engaged to the ground, for example buried in the ground. Alternatively, the other end is connected by a base buried in the ground.

That is to say, building foundation afforests and maintains structure still includes the base with the support column cooperation, therefore, the other end of support column is fixed in ground through the base indirectly. In one embodiment, the other end of the support post is removably connected to the base. For example, the other end of the support post is threaded and correspondingly, the base is threaded. For example, the other end of the supporting column 200 is configured to include a fixed portion 2031 and a movable portion 2032, as shown in fig. 5. The movable portion 2032 is T-shaped and has threads on its shank, not shown. And the fixing portion 2031 is filled in the support pillar 200, and the fixing portion 2031 has a blind hole with smooth inside, and the moving portion 2032 is sleeved on the blind hole in a manner of rotating along the axial direction of the blind hole. And the movable portion 2032 has a threaded end that is threadedly coupled to the threaded hole of the base.

For better results, the support posts may be arranged to be able to rock properly. Referring to fig. 6, the base 300 includes a body 301 and a movable block 302, the body 301 includes a recess 3011, the movable block 302 is hinged to the recess via a pivot 303 provided with a torsion spring so as to allow the movable block 302 to swing around the pivot 303, and a screw hole is disposed in the movable block. In the base, a part of the body is buried in the ground. While the active mass is exposed or slightly shielded. Preferably, the body of the base has a pointed cone which allows it to be easily inserted into hard ground to improve grip.

In order to realize the motion control of the movable rod, a plurality of thrust plates, an elastic plate and a plurality of thrust plates are arranged inside the support column. Wherein the elastic plate is located between the plurality of thrust plates and the plurality of thrust plates. The support column 200 is matched with the movable rod 400 in a manner as shown in fig. 7.

All the thrust plates are arranged in the rear section 203 of the support column; all the anti-pulling plates are arranged in the rear section 201 of the supporting column; a resilient plate is disposed within the middle section 202.

The pulling-resistant plate 401 is provided with three plates, and the three plates are fixed inside the front section 201 at intervals along the axial direction of the support column. Wherein each pulling-prevention plate 401 has through holes 4011 distributed along the axial direction of the support column. The distribution and the construction mode of three anti-pulling plates are as follows:

the second distance D between two adjacent pulling-resistant plates 401 gradually decreases in the direction from the rear section 203 to the front section 201, direction a in fig. 8.

In the direction from the rear section to the front section, the direction a in fig. 8, the compressive strength of each tension-preventing plate gradually increases, and this is achieved by the selection of the material.

In the direction from the rear section to the front section, the diameter of the through hole of each tension preventing plate is gradually reduced in the a direction in fig. 8.

Accordingly, the elastic plate 402 is disposed along a cross section of the middle section. The elastic plate 402 is made of an elastic material. For example, the elastic plate is made of spring steel. The end of the movable rod is connected (e.g., fixedly connected by welding) to the elastic plate 402.

All the thrust plates 403 (three in the drawing) are fixed to the inside of the rear section 203 at intervals in the axial direction of the support column. With respect to the tension mask 401 having the through hole 4011, the thrust plate 403 is a solid plate material.

A first distance D2 between two adjacent thrust plates 403. Gradually increasing in the direction from the front section to the rear section, direction B in fig. 8.

The compressive strength of each thrust plate gradually increases in the direction from the front section to the rear section, the direction B in fig. 8.

Referring to fig. 9, the movable rod 400 passes through all the through holes of the anti-pulling plate and is sleeved inside the supporting column, and is also located inside the front section 201. Accordingly, one end of the movable rod 400 is connected to the elastic plate 402 while the other end of the movable rod 400 protrudes out of the support column 200 to be connected to the ferrule 100, and the diameter of the movable rod 400 is gradually reduced from one end to the other end.

The elastic plate 402 can serve as a buffer. Therefore, when the movable rod moves along the axial direction of the support column, the end part of the movable rod can play a pulling or pushing/extruding effect on the elastic plate. Within a certain acting force range, the elastic plate can play a good buffering effect. Thus, when the tree slightly shakes, the elastic plate can play a role of buffering.

When the stress of the elastic plate exceeds the bearing limit of the elastic plate, the elastic plate can be buffered through the anti-pulling plate or the thrust plate according to the movement direction of the movable rod; while in these cases the elastic plate is punctured or chipped by the movable rod. Wherein, when the movable rod is far away from the support column, the pull-preventing plate of the front section buffers. When the movable rod goes deep into the supporting column, the movable rod is buffered by the thrust plate at the rear section.

Wherein, prevent the direction that the pulling plate is kept away from the support column along the movable rod, D reduces gradually. Thus, the more outward the movable rod moves, the more stressed the tree is, and therefore, the more frequently it is restrained by the anti-drag plate. Therefore, the above-described limitation is made to the spacing between the pulling prevention plates. And, the closer to the end of the front section in the direction a, the better the pulling force resistance of the pulling-resistant plate.

Correspondingly, when the movable rod is deep into the rear section of the supporting column, the thrust rod delays or buffers the impact driving force of the rod layer by layer. Through layer-by-layer buffering, the stress can be remarkably reduced, so that the movement of the movable rod is not too violent, and the shaking degree of the tree is reduced. In addition, different from the arrangement mode that the distance between the pulling-proof plates in the front section is gradually reduced, the distance between the thrust plates in the rear section is gradually increased, and the phenomenon that the acting force on the tree is too large due to the fact that the hoop is rapidly stopped is avoided.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
