Description

Post assembly that can be installed on the upper structure {PILE ASSEBLY WHICH BE ABLE TO INSTALL UPPER STRUCTURE}

The present invention relates to a post assembly capable of installing an upper structure, and more particularly, the installation of an upper structure that enables installation of various upper structures, including solar panels, on the upper end of the post exposed from the ground after burial in the ground. It relates to possible strut assemblies.

The pile 110 having a H Beam structure is generally a dedicated hammer device 210 of the arm 320 end rotatably coupled to the boom 310 of the excavator as shown in FIG. It is possible to bury it underground with help.

Since the hammer device 210 is mounted in a structure inclined toward the ground, the long pile 110 has a limitation in that the size and length of the boom 310 and the arm 320 must be large to be able to be buried. exist to exist

Since the burying operation of the pile 110 by the hammer device 210 is performed by a mechanism such as hitting a hammer and driving a nail, there is a problem in that a very large noise is generated.

And, in the burial operation of the pile 110 by the hammer device 210, maintaining the perpendicularity of the pile 110 with respect to the ground is most important, but the pile 110 is tilted because it fails to maintain the above-mentioned perpendicularity. If it is embedded, it is extremely difficult to remove the already embedded pile 110 from the ground.

In particular, the burying operation of the pile 110 by the hammer device 210 has a problem in that it takes a lot of time to complete the operation in an underground environment with a lot of gravel or a very hard bedrock.

In addition, the burying operation of the pile 110 by the hammer device 210 increases the time required for the installation of the hammer device 210 and the hammering and burying of the pile 110 , and it varies greatly depending on the situation of the workplace. There was a problem in that it was difficult to predict the exact air.

In addition, since the burial operation of the pile 110 by the hammer device 210 causes the upper end of the H beam structure to be crushed by the hammering of the hammer device 210, a phenomenon occurs, There was also a problem that required additional processing or re-construction, such as trimming and cutting the crushed part, when it was buried and a separate pile was connected on it or an upper structure had to be installed.

On the other hand, the general screw-shaped pile 120 including the "construction device for screw pile" of Patent No. 10-1715348 is an arm 320 rotatably coupled to the boom 310 of the excavator as shown in FIG. 10(b). It is connected to the dedicated drill device 220 at the end of the underground burial work is in progress.

However, the burial operation using the screw-shaped pile 120 has a small noise generated during operation compared to the H-beam type pile 110, but once the pile 120 starts to be embedded in the ground, the pile 120 for the ground ), there is a problem in that it is difficult to maintain the perpendicularity.

The screw-shaped pile 120 has no choice but to be manufactured in a cylindrical shape as a whole because of the spiral-shaped blade structure.

Because, if the central axis structure of the pile is a polygonal column shape such as a square or hexagonal column, the inner edge of the spiral blade is cut to fit the outer surface of the polygonal column shape, and then the inner edge of the blade and the outer surface of the polygonal column shape There was a problem that it was difficult to weld them one by one.

In particular, the screw-shaped pile 120 has a clear limitation that an additional structure cannot be mounted on the upper end of the pile 120 due to the structural characteristics for connection with the drill device 220 at the upper end protruding from the ground after burial.

In addition, the screw-shaped pile 120 has a structural limitation in that it is difficult for the blade to actually crush a relatively large crushed object such as gravel or rock when there is gravel or rock in the ground.

Therefore, there is no difficulty in maintaining perpendicularity with the ground by overcoming the limitations and problems of the existing technology, and it is urgent to develop a device that can provide convenience in work such as separating from the ground and burying it again when it is out of perpendicularity.

The present invention is a hub assembly 20 in a hollow pipe 10 having an upper end that can be installed an upper structure (hereinafter not shown) and a lower end buried in the ground (hereinafter not shown) as shown in FIG. ), it can be seen that the structure is provided.

The hub assembly 20 is coupled to the lower end of an excavation rod (hereinafter not shown) inserted through the pipe 10, excavates from the ground surface where the pipe 10 is to be installed, and extends the lower end and the lower side of the pipe 10 into the ground. It is designed to perform the role of burial.

The present invention can be applied to the above embodiments, and it will be of course also possible to apply the following various embodiments.

First, when the angle formed by the pipe 10 with respect to the ground is out of a right angle in the process of being buried underground, the pipe 10 rotates the excavation rod in the opposite direction to the direction of rotation for the underground burial direction to rotate the hub assembly 20 It is also possible to completely separate the pipe 10 from the ground by raising the pipe 10 toward the ground to a certain extent.

In addition, the pipe 10 rotates the excavation rod again in the rotation direction for the underground burial direction, so that the hub assembly 20 and the pipe 10 can be buried again while maintaining a right angle with respect to the ground.

Here, the hub assembly 20 is buried and fixed in the ground together with the pipe 10 .

At this time, the pipe 10 may be buried in a line connected in a plurality of up and down.

Meanwhile, in order to increase the rigidity of the pipe 10, the following method may be considered.

First, it is possible to consider a method of using a pipe having a large difference between the inner diameter and the outer diameter of the pipe 10 itself, that is, a pipe made of a thick metal material.

However, this method may face the problem of increasing the cost of raw materials.

As another method, a method of curing by pouring concrete or pouring concrete from the top of the pipe 10 exposed from the ground immediately after the underground burial is completed may be adopted as another method.

Therefore, it is of course possible to use an appropriate method and raw material according to the situation of the construction site among the above-described construction methods.

Meanwhile, the present invention may further include a connect wing (30, connect wing) when looking in more detail with reference to FIGS. 2 and 3 together with FIG. 1 .

The connect wing 30 may be installed on the outer surface of the pipe 10 .

In addition, the connect wing 30 may be installed so that the upper end of one pipe 10 and the lower end of the adjacent pipe 10 among the plurality of pipes 10 that are connected in a line up and down and are buried can be interconnected.

In addition, the connect wing 30 also serves to prevent the pipe 10 from rotating in conjunction with the rotary excavation of the hub assembly 20 .

The connect wing 30 may include largely first and second divided bodies 31a and 31b and first and second coupling pieces 32a and 32b.

The second divided body 31b has an inner surface of a shape corresponding to the outer surface of the pipe 10, is in contact with the rest of the outer surfaces of the pipe 10, and is in contact with the pipe 10 together with the first divided body 31a. covers the entire outer surface of

The first coupling pieces 32a extend from both edges of the first divided body 31a, respectively.

The second coupling pieces 32b are respectively extended from both edges of the second divided body 31b to be fixed in contact with the first coupling pieces 32a.

That is, the first and second coupling pieces 32a and 32b are formed to extend from both edges of the first and second divided bodies 31a and 31b, respectively, so that the drill head 21 of the hub assembly 20 to be described later rotates and Even in the process of excavation, it maintains a fixed state in the ground and performs a function of preventing the pipe 10 from rotating together in conjunction with the rotary excavation of the drill head 21 .

On the other hand, the connect wing 30 is a first engaging embossed structure that protrudes or sinks toward the outer surface of the pipe 10 on the inner surface of the first divided body 31a and the second divided body 31b (hereinafter not shown). city) may be further provided.

In addition to this, the outer surface of the pipe 10 may further include a second engaging embossing structure (not shown below) that is depressed or protruded toward the inner surface of the first divided body 31a and the second divided body 31b. is of course

The above-described first and second interlocking embossed structures are technical means provided to prevent the connect wing 30 from flowing down or slipping away from the pipe 10 .

In other words, the connect wing 30 prevents the pipe 10 from interlocking rotation with the drill head 21 , and at the same time connects the plurality of pipes 10 in a vertical line and burying them in the underground, the length of the pipes 10 . It also functions as a fixed connection structure for maintaining the extension structure.

Meanwhile, the pipe 10 may be formed in one or a combination of at least one of a cylindrical shape, an elliptical columnar shape, or a polygonal column shape.

Accordingly, the inner surface of each of the first divided body 31a and the second divided body 31b may have a semi-circular or semi-elliptical or polygonal half shape to match the shape of the outer surface of the pipe 10 .

Meanwhile, the hub assembly 20 may include a drill head 21 , an end plate 22 , a push plate 23 , and a blade 24 .

The drill head 21 has an upper surface that is detachably coupled to the lower end of the excavation rod.

The end plate 22 is coupled to the lower end of the pipe 10 to support the rotation of the drill head 21 .

The pressing plate 23 is coupled to the drill head 21 to regulate separation of the drill head 21 from the pipe 10 .

Therefore, with respect to the end plate 22 fixed to the pipe 10 by welding, the pressing plate 23 welded to the outer peripheral surface of the drill head 21 exposed from the lower end of the pipe 10 is welded to the drill head 21 . rotates together with

On the other hand, the drill head 21, looking in more detail with reference to FIG. 6 together with FIGS. 4 and 5, includes an insertion part 21a, a stepped sleeve 21b, a drill bit 21c, and a blade 24. can do.

The insertion portion 21a is formed in a cylindrical shape having a first diameter D1 having an upper surface formed with a coupling groove 21g having a shape corresponding to the lower end of the excavation rod.

The stepped sleeve 21b has a second diameter D2 that is smaller than the first diameter D1, is formed to protrude stepwise from the lower surface of the insertion part 21a, and is a first through hole 22b penetrating through the center of the end plate 22. ) is formed in a cylindrical shape with an inner peripheral surface and an outer peripheral surface facing each other.

The drill bit 21c has an upper end having a third diameter D3 smaller than the second diameter D2 and is gradually narrowed toward the lower end.

The lower end of the drill bit 21c is provided with a drill bit for burying the pipe 10 while rotating with the driving force transmitted through the excavation rod in contact with the ground, excavating and crushing into the ground.

At least one blade 24 is formed on the outer circumferential surface of the drill bit 21c to crush or push out gravel and rocks during underground excavation to assist in the excavation and descent of the drill head 21 .

Here, the insertion portion 21a is inserted into the lower end of the pipe 10, and at the same time, is rotationally supported by the end plate 22 welded to the lower end of the pipe 10, and the pressing plate 23 is the drill bit 21c. ), it can be seen that welding is fixed to the upper part.

Meanwhile, the end plate 22 may include a first body 22a, a first through hole 22b, and a chamfer 22c, when looking more specifically with reference to FIG. 7 together with FIGS. 4 and 5 . have.

The first body 22a is formed in a rectangular block shape that is greater than or equal to the area formed by the lower end surface of the pipe 10 .

The first through hole 22b is penetrated in the center of the first body 22a to allow penetration and rotation of the drill head 21 .

The chamfer 22c is formed by cutting up and down at least two of the four corners formed by the four sides of the rectangular block.

Here, the end plate 22 is welded to and fixed to the pipe 10 , and is provided to prevent the hub assembly 20 from being separated from the lower end of the pipe 10 by spanning the first through hole 22b.

The above-described chamfer 22c is provided to smoothly discharge zinc solution during hot-dip galvanizing to increase durability and corrosion resistance after welding the end plate 22 to the pipe 10 .

On the other hand, the pressing plate 23, looking more specifically with reference to FIG. 8 together with FIGS. 4 and 5, has a rhombic block-shaped second body 23a having an upper surface facing the lower surface of the end plate 22. And, it may include a second through hole (23b) penetrated in the center of the second body (23a) and having an inner peripheral surface facing the outer peripheral surface of the drill head (21).

Here, it can be seen that the second body 23a is welded to the drill head 21 along the edge of the second through hole 23b.

At this time, the pressing plate 23 is welded and fixed to the outer peripheral surface of the upper end of the drill head 21 , specifically, the drill bit 21c to rotate together with the drill bit 21c, and the hub assembly 20 is the pipe 10 . to prevent it from being pushed into the inside of the

In addition, the pressing plate 23 prevents soil or foreign substances from being pushed into the pipe 10 through the chamfer 22c of the end plate 22 and also serves to push out.

The diagonal horizontal length L1 of the above-mentioned rhombus is greater than the diagonal vertical length L2, and it can be seen that the two corners of the rhombus having a diagonal horizontal length L1 protrude from both sides of the lower end edge of the end plate 22. It can be confirmed that .

On the other hand, the blade 24 is a structure including a blade body 24a, a crushing force dispersing part 24b, and a crushing material extruding part 24c, looking more specifically with reference to FIG. 9 together with FIGS. 4 and 5. can figure out

The blade body 24a is formed in a rectangular shape that is inclined upward or downward with respect to an imaginary line ℓ passing through the center of both upper and lower ends of the drill head 21 .

The crushing force dispersing part 24b is a rectangular-shaped inner edge s1 having an arc-shaped installation groove 24g coupled to the outer circumferential surface of the drill head 21, and a rectangular-shaped outer edge s2. It is formed to protrude in an arc shape along one edge (s3) of both edges (s3, s4) to be connected.

The crushing force dispersing part 24b is to be recessed in an arc shape along the other edge s4 of both edges s3 and s4.

The crushing force dispersing part 24b and the crushing material extruding part 24c are designed in consideration of the load generated when the blade 24 rotates in conjunction with the drill head 21, that is, the drill bit 21c and is excavated into the ground. will be.

The curvature ratio (a/b) of the radius of curvature (a) of the crushing force dispersing part (24b) and the radius of curvature (b) of the crushing material extrusion part (24c) is preferably about 0.7.

Here, the protruding arc shape (a, b, and a/b) of the crushing force dispersing part 24b occurs with respect to the soil, gravel and rocks in the ground when the blade 24 rotates together with the drill bit 21c. It can be said to be the optimal design in structural analysis to properly and smoothly distribute the shear stress.

At this time, the subterranean arc shape of the crushed material extruding unit 24c is formed as the crushing force dispersing unit 24b first crushes the underground soil, gravel, and rock and rotates smoothly to return to the lower side of the underground soil. It can be said that it is the optimal design in structural analysis to gently and smoothly push out the stones crushed by the drill bit 21c and the drill bit 21c.

That is, by forming the curvature of the crushed material extruding part 24c to be greater than or equal to the curvature of the crushing force dispersing part 24b, various crushed objects that collide in the ground with a strong force, that is, soil, gravel or rocks, are smoothly crushed and pushed to be able to pay

In addition, by forming the curvature of the crushed material extrusion portion 24c equal to or smaller than the curvature of the crushing force dispersing portion 24b, as described above, the crushed material is smoothly pushed along the periphery of the crushed material extrusion portion 24c. is designed with

On the other hand, the blade 24 is, again with reference to FIGS. 4 and 5 (a), when looking more specifically, the first blade ( 241 , and a second blade 242 formed to be inclined downward with respect to the virtual line ℓ and fixed to the other side of the outer peripheral surface of the drill head 21 .

Here, the first inclination angle θ1 formed by the first blade 241 and the second blade 242 crossing the imaginary line ℓ when viewed from the side of the drill head 21 is the imaginary line ℓ The second inclination angle θ2 formed by the first blade 241 or the second blade 242 may be formed to be equal to or smaller than that of the .

That is, the first inclination angle θ1 is 20° to 50°, and the second inclination angle θ2 may be appropriately selected within the range of 40° to 70° to be designed and manufactured.

In this case, the first inclination angle θ1 is preferably 35°±2.5°, and more preferably within 35°.

In addition, the second inclination angle θ2 is preferably 55°±2.5°, and more preferably within 55°.

If the range of the first inclination angle θ1 is less than 20 degrees or exceeds 50 degrees, the crushing effect according to the rotation of the drill bit 21c may not be obtained.

That is, when the disposition angle of the first blade 241 and the second blade 242 is in the above-mentioned abnormal range, even if the drill bit 21c rotates, it takes a lot of force to crush the objects to be crushed, and accordingly, the first blade ( 241) or the second blade 242 will be faced with a risk of being bent or damaged.

In other words, when the first inclination angle θ1 at which the first blade 241 and the second blade 242 cross each other is less than 20 degrees, it is almost the same as a structure in which only a single disk is installed, so when rotating the drill bit 21c It will have little effect on repelling the blood shreds.

In addition, when the first inclination angle θ1 at which the first blade 241 and the second blade 242 intersect each other exceeds 50 degrees, the first blade 241 and the second blade 242 are drill bit ( 21c) and, in the process of underground excavation by rotating the drill bit 21c, since it has an arrangement structure of a level arranged almost side by side with the first blade 241 and the second blade 242, the crushing force dispersing part 24b of each If a very large load is applied, the risk of problems such as breakage or bending will increase.

Similarly, if the range of the second inclination angle θ2 is less than 40 degrees or exceeds 70 degrees, the crushing effect according to the rotation of the drill bit 21c may not be obtained.

That is, when the disposition angle of the first blade 241 and the second blade 242 is in the above-mentioned abnormal range, even if the drill bit 21c rotates, it takes a lot of force to crush the objects to be crushed, and accordingly, the first blade ( 241) or the second blade 242 will be faced with a risk of being bent or damaged.

In other words, when the second inclination angle θ2 formed by the first blade 241 and the second blade 242 with respect to the virtual line ℓ is less than 40 degrees, the first blade 241 and the second blade 242 are Since the drill bit 21c and the drill bit 21c have a level arrangement that is arranged almost side by side, the first blade 241 and the second blade 242 each have a crushing force distribution unit ( 24b) will be subject to a very large load, which will increase the risk of problems such as breakage or bending.

In addition, when the second inclination angle θ2 formed by the first blade 241 and the second blade 242 with respect to the virtual line ℓ exceeds 70 degrees, it is almost the same as the structure in which only a single disk is installed, so the drill bit When rotating (21c), there will be little effect of repelling the crushed object.

As described above, the present invention has no difficulty in maintaining perpendicularity with the ground, and when it is out of perpendicularity, it is separated from the ground and buried again. It provides a post assembly capable of installing an upper structure that can provide convenience of work. It can be seen that this is a basic technical idea.

And, within the scope of the basic technical spirit of the present invention, many other modifications and applications are also possible for those of ordinary skill in the art.
