Description

FIELD OF THE INVENTION

The present invention relates to a mechanical foundation for use in construction. More so, the present invention relates to a root-like foundation that has bumping and extendable feet for loading the construction above is introduced herein.

BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

Foundation is an important part of a building construction process which costs a lot of labor and time. In the traditional method, there are different kinds of foundations such as pile foundations, raft foundations, and so on. However, most of them are made of reinforced concrete and the average construction time for the foundation is one month. There is rarely a prefabricated foundation. The problem with existing foundations is the long construction period and the tendency to settle in soft soils, leading to foundation subsidence, which in turn leads to building instability.

To solve the above problems, the present invention is proposed. This invention creates a mechanical foundation that is root-like. The blades will expand out for a larger contact surface with soil. It reduces the chance of settling and increases the foundation building efficiency.

Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.

FIG. 1A and FIG. 1B illustrate how the root-like mechanical foundation works inside the soil and a schematic view of the mechanical foundation when all blades are unfolded.

The mechanical foundation can have only one mechanical foundation component, or the mechanical foundation can be composed of multiple mechanical foundation components that have the same configurations.

The mechanical foundation can also have two mechanical foundation components. In this scenario, the mechanical foundation components are the top mechanical foundation component and the bottom mechanical foundation component. The support ring of the top mechanical foundation component may be mounted on the cylindrical housing of the bottom mechanical foundation component.

The mechanical foundation can also have one or more middle mechanical foundation component between the top and the bottom mechanical foundation components. FIGS. 1A, 1B, 2A, 2B, 5A, 5B, 8A, 8B, 8C illustrate one middle mechanical foundation component as examples.

The mechanical foundation 10 is composed of three components, i.e., the top mechanical foundation component 100, the middle mechanical foundation component 200, and the bottom mechanical foundation component 300. After the blades 103, 203, and 303 expand, they will insert into soil 40 as the fibrous roots of a tree. The whole mechanical foundation 10 looks like a root of a tree. Thus, the mechanical foundation 10 is a root-like foundation. The top of the top mechanical foundation component 100 may cover with a platform depending on the upper structure. The bottom of the bottom mechanical foundation component 300 may be connected a ground drilling unit such as a drill. As shown in the drawings, the root-like mechanical foundation 10 has a relatively larger contact surface with soil 40. Therefore, it reduces the pressure on the soil when loading for the same quantity.

FIG. 2A and FIG. 2B illustrate the initial status that all blades are folded inside the mechanical foundation 10. FIG. 2A is a front view. FIG. 2B is a schematic view. Before being driven into the ground, all the blades are folded inside the mechanical foundation 10 to reduce the resistance when entering the ground. After being driven into the ground at the designated location, all blades are unfolded to increase the stability of the foundation as FIG. 1A shows.

FIG. 3A and FIG. 3B illustrate the internal setup of the mechanical foundation component 10. FIG. 3A illustrates the status that all the blades 103 are folded. FIG. 3B illustrates the status that all the blades 103 are unfolded.

The mechanical foundation component 100 for use in construction includes a support ring 101; a plurality of rotary shafts 102, each rotary shaft 102 is rotatably positioned on the surface of the support ring 102; a plurality of blades 103 are mounted on the rotary shafts 102 and rotate with the rotary shaft 102; a plurality of blade gears 104 are fixed to the rotary shaft 102 and rotate with the rotary shafts 104 and the blades 103; a gear ring 105 engages with all the blade gears 104 and drives all the blade gears 104 to rotate at a same angular velocity. The gear ring 105 is coaxial to the supporting ring 101. The gear ring 105 is engaged with the drive gear 108 on the control rod 107 (not shown in FIG. 3A and FIG. 3B, the control rod 107 with the drive gear 108 is shown in FIG. 8A and FIG. 9B). The rotation of the control rod 107 can be driven and controlled by an external drive, such as a motor (not shown).

The rotation of the control rod 107 generates the rotation of the drive gear 108. The drive gear 108 drives one of the blade gear 104 with which it engages to rotate; the blade gear 104 drives the gear ring 105. The rotation of gear ring 105 drives the synchronized rotation of all the other blade gears 104 with which it engages. Each blade gear 104 and blade 103 is fixed to each other, and both rotate around their respective rotary shaft 102. Thus, the rotation of the control rod 107 drives and controls the rotation of the blades 103. Further, the rotation of the control rod 107 can enable the blades 103 to turn inside or outside the mechanical foundation component 100 as needed.

FIG. 4A illustrates the blade gear with a blade gear shaft; FIG. 4B illustrate a schematic view of a mechanical foundation component with blade gear shafts.

Each blade gear 104′ extends upward in direction of the axis of each blade gear 104′ to form a blade gear shaft 102′. The inner wall of each blade gear 104′ joins and rotates integrally with the part of the outer cylindrical surface of each rotary shaft 102 that overlaps. Accordingly, the shaft 102′ rotates synchronously with the shaft 102.

The drive gear 108 drives one of the blade gear 104′ with which it engages to rotate; the blade gear 104′ drives the gear ring 105. The rotation of gear ring 105 drives the synchronized rotation of all the other blade gears 104′ with which it engages. Each blade gear 104′ and blade 103 is fixed to each other, and both rotate around their respective rotary shaft 102 and the blade gear shaft 102′. Thus, the rotation of the control rod 107 drives and controls the rotation of the blades 103. Further, the rotation of the control rod 107 can enable the blades 103 to turn inside or outside the mechanical foundation component 100 as needed.

In another embodiment (not shown in drawings), the rotation of the control rod generates the rotation of the drive gear. The drive gear drives the gear ring, with which it engages to rotate. The rotation of gear ring drives the synchronized rotation of all the blade gears with which it engages. Each blade gear and blade are fixed to each other, and both rotate around their respective rotary shaft. Thus, the rotation of the control rod drives and controls the rotation of the blades.

The mechanical foundation component 100 further has a cylindrical housing 106 to protect the gears 103 and other inner structures. FIG. 5A is the schematic view of the cylindrical housing. FIG. 5B is the bottom view of the cylindrical housing. The cylindrical housing 106 has a top wall 1061, an inner cylinder 1062 extending downward from the top wall 1061, and an outer wall 1063 extending down along circumference of the top wall 1061. The inner cylinder 1062 is securely connected to the support ring 101. This results in a sturdy structure. The outer wall 1063 covers the blade gears 103 and the gear ring 105. This protects the internal structure from dirt ingress causing seizure. The bottom surface of the outer wall 1063 is higher than the upper surface of the support ring 101 in the vertical direction. The height difference between the two surfaces allows blades 103 to freely rotate inside or outside the mechanical foundation component 100.

As FIG. 5A and FIG. 5B show, the bottom surface of the top wall 1061 is provided with a plurality of blind holes 1064 to accommodate rotary shafts 102 or the blade gear shaft 102′. The top wall 1061 has a first through hole 1065 to accommodate the control rod 107. When the mechanical foundation 10 is composed of three mechanical foundation components 100, 200, and 300, each top wall of the mechanical foundation components will have first through holes to accommodate the control rods. In FIG. 5A and FIG. 5B, two more first through holes 1066 and 1067 are illustrated.

FIG. 6A is the schematic view of the supporting ring with rotary shafts. FIG. 6B is the top view of the supporting ring with rotary shafts and blades. In folded status, all the blades are inside the mechanical foundation component 100. As a result, it is easy to transport and will reduce resistance when drilling into the land, facilitating fast drilling. The rotary shafts 102 are distributed in equal radians along the circumference of the support ring 101. As a result, the individual blades 103 are subjected to the same forces, improving the mechanical foundation's overall life.

FIG. 7A is the schematic view of a blade. FIG. 7B is the top view of a blade. Each blade 103 has a mounting end with a mounting hole 1031 mounted on each rotary shaft 102, and a cutting end 1032 is driven to rotate toward inside or outside the mechanical foundation component 100. Edges of blade 103 are chamfered. This makes blade 103 easier to cut into the soil when the blades are turned outside. In another embodiment, the surface of the blades is bumping. This provides the advantage that when the blade 103 reaches the designated position and enters the working state, the bumping surface can provide greater friction to make the mechanical foundation more stable.

FIG. 8A is the schematic view of the mechanical foundation component (the cylindrical housing is not shown). FIG. 8B is the top view of the mechanical foundation component (the cylindrical housing and the control rod 107 are not shown). The support ring 102 has a through hole 1011 or a blind hole (not shown) to accommodate the control rod 107.

When the mechanical foundation 10 is composed of three mechanical foundation components 100, 200, and 300, the support ring of the top and the middle mechanical foundation components will have three first through holes to accommodate the control rods. The support ring of the bottom mechanical foundation component will have three second through holes or three blind holes to accommodate the control rods. In FIG. 8A and FIG. 8B, two more second through holes 1012 and 1013 are illustrated.

FIG. 9A is the schematic view of the top mechanical foundation component in the mechanical foundation (the middle and bottom mechanical foundation components are not shown). FIG. 9B is the schematic view of the top mechanical foundation component in the mechanical foundation (the cylindrical housing of the top mechanical foundation component is not shown; the middle and bottom mechanical foundation components are not shown). FIG. 9C is the front view of the top mechanical foundation component in the mechanical foundation (the middle and bottom mechanical foundation components are not shown). In FIGS. 8A, 8B, and 8C, the control rod 107 of the top mechanical foundation component 100, the control rod 207 of the middle mechanical foundation component 200, and control rod 307 of the bottom mechanical foundation component 300 are shown. Corresponding drive gears 108, 208, and 308 are also shown in FIG. 9B. The three drive gears 108, 208, and 308 independently control the folding or unfolding of the blades 103, 203, and 303 on the three mechanical foundation components 100, 200, and 300, thus enabling greater flexibility. FIG. 6 illustrates the cover platform of the mechanical foundation. The foundation 10 further includes a platform 400 set on top of the topmost cylinder 100; the platform 400 includes: a first cylindrical portion 410; and a second cylindrical portion 420; both the first cylindrical portion 410 and the second cylindrical portion 420 are co-axial with the cylinder 100; the lower surface 4110 of the first cylindrical portion is recessed upward to form a cylindrical space with an annular wall 4120; the second cylindrical portion 420 is mounted on the lower surface 4110 of the first cylindrical portion 410 and extends downward; the lower surface 4110 of the first cylindrical portion is provided with a plurality of blind holes 4130 for holding the mounting shafts 250; the second cylindrical section further includes at least one control rod through-hole 4210.

Refer to FIG. 2A and FIG. 2B. The mechanical foundation 10 is composed of a top mechanical foundation component 100, a middle mechanical foundation component 200 and a bottom mechanical foundation 300, the top mechanical foundation component 100, the middle mechanical foundation component 200, and the bottom mechanical foundation component 300 are connected in order from top to bottom. Each mechanical foundation component has the same structure as mentioned above. The top mechanical foundation component 100 includes a support ring 101, a plurality of rotary shafts (not shown), a plurality of blades 103, a plurality of blade gears (not shown), a gear ring (not shown), a cylindrical housing 106, and a control rod 107 with a drive gear (not shown); the middle mechanical foundation component 200 includes a support ring 201, a plurality of rotary shafts (not shown), a plurality of blades 203, a plurality of blade gears (not shown), a gear ring (not shown), a cylindrical housing 206, and a control rod 207 with a drive gear (not shown); the bottom mechanical foundation component 300 includes a support ring 301, a plurality of rotary shafts (not shown), a plurality of blades 303, a plurality of blade gears (not shown), a gear ring (not shown), a cylindrical housing 306, and a control rod 307 with a drive gear (not shown).

The control rods 107, 207, and 307 go through all the mechanical foundation components 100, 200, and 300. On each mechanical foundation component, there is a corresponding drive gear 108, 208, or 308 to control the folding or unfolding of the blades 103, 203, or 303.

The support ring 101 of the top mechanical foundation component 100 is mounted on cylindrical housing 206 of the middle mechanical foundation component 200; the support ring 201 of the middle mechanical foundation component 200 is mounted on cylindrical housing 306 of the bottom mechanical foundation component 300.

  • c. drive the blades 103, 203 and 303 of each mechanical foundation components 100, 200, and 300 to extend outward from inside of the mechanical foundation 10.

When driving blades of the same mechanical foundation component, each blade turns at the same angle synchronously. Blades of different mechanical foundation components rotate synchronously or asynchronously. Blades of different mechanical foundation components extend outward at the same or different angles as needed.
