Description

Implant-type pile press-in device and implant-type filing method using the same in building foundation system

The present invention relates to an implant-type pile press-in device in a building foundation system and an implant-type filing method using the same, and to form a foundation system using a reaction force such as a building's own weight, and more particularly, to construct a foundation system of a building An implant-type pile press-in device that can be embedded and transplanted into the foundation slab of a new structure in advance to form a pile foundation later or to restore deformation caused by floating settlement of a building, and to press-in piles used for extension or remodeling; and It relates to an implant-type filing method using the same.

Recently, along with the increase of old buildings, extension and remodeling construction that can extend social and physical lifespan by improving various functions required for existing buildings is actively progressing.

In particular, in order to additionally extend the basement, the ground must be reinforced to support the structure's own weight, but since there was no reliable ground reinforcement method, the conventional ground reinforcement method had to be used prior to the construction of the structure.

As a conventional ground reinforcement method, there is a micro-piling method, etc. In the case of this conventional ground reinforcement method, the depth of reinforcement is limited because there is a limit to the size of equipment that can enter the structure. There was a problem that I couldn't confirm.

The Republic of Korea Patent No. 10-0621669 "Structure raising and foundation reinforcement method using a press-in body" has been proposed in place of this conventional ground reinforcement method.

1 is a conceptual diagram illustrating a method of raising a structure and a foundation reinforcement using a conventional press-in body.

In this method, it is possible to press-in piles when the field work conditions are very bad or when the foundation construction using equipment is difficult, but the function of the structure is restored by reinforcing and raising the foundation for the structures that have been constructed on soft ground and have had unequal settlement. It is a pile press-in construction method that can raise only the minimum necessary parts without completely removing or dismantling structures that require repair or reinforcement, and a construction method that can serve as both foundation reinforcement.

That is, as shown, first, a reaction force hole 120 is drilled in the bottom plate 110 of the structure 100 in order to install the reaction force support 200, and then a reaction force ball such as a reinforcing bar or a steel bar is formed in the reaction force hole 120 ( 210) by penetrating the lower end of the structure to fix it on the bottom of the structure, and by installing the upper support 220 in the form of a circular plate located inside the structure 100 at the upper end of the reaction force sphere 210, artificially the reaction force support (200; 210, 220) is installed in the structure, and the press-in body 300 in the form of a pile such as a steel pipe is set in the press-in hole 130 drilled to a predetermined depth like the reaction force hole 120 in the lower part of the upper support 220, and the press-in body ( 300) and the upper support by operating the press-in means 400 including a hydraulic cylinder to press-in the press-in body 300 into the lower part of the structure 100, and then hydraulic pressure between the press-fitted press-in body 300 upper part and the upper plate of the structure By installing a lifting means including a cylinder, it was eventually possible to raise the submerged structure by the lifting means.

However, in the case of the existing method, it is necessary to drill several press-fitting holes and reaction force holes in the floor foundation slab around the column of the structure.

Therefore, the strength of the floor foundation slab of the existing structure is rather weakened, and there is a risk of weakening the bearing capacity of the existing structure during extension. In addition, in order to prevent this, the problem of having to reinforce it separately arose.

And since the rod-shaped reaction force ball and the upper support body must be assembled with a nut, the structure is complicated and a lot of time is consumed in assembling it.

Accordingly, the present invention is to solve the above problems, and an object of the present invention is to form a pile foundation or a building later by burying and transplanting in the foundation slab of a new structure in advance in the step of constructing a building foundation system when a structure is newly constructed. An implant-type pile press-in device is provided in a building foundation system consisting of a pile installation tool that can press-in a pile and a reaction force support pipe that supports the reaction force of the hydraulic jack when restoring the deformation caused by the immobility settlement of will be.

Another object of the present invention is to provide an implant-type pile press-in device using a reaction force support pipe that has a simple structure and can be easily and quickly assembled in a pile installation port.

And another object of the present invention is to press-in and construct piles for pile foundation formation, deformation restoration due to immobility settlement, extension or remodeling using implanted pile installation tools buried and implanted in advance at the stage of constructing the building foundation system. It is to provide a filing method using an implant-type pile press-in device in a building foundation system that can be built.

The implant-type pile press-in device in the building foundation system according to the present invention for achieving the above object is an apparatus for press-fitting the pile in the building foundation system, and is made in a pipe shape so that the pile can be inserted, and is A pile installation hole in which a male screw thread is formed, an upper flange and a lower flange are formed in the upper and lower portions, respectively, so that they can be buried and transplanted into the foundation slab of the new structure; a reaction force support pipe made of a pipe shape to accommodate a pile, a female threaded part is formed at the lower end, and is fastened with the male threaded part, and an opening is formed on both sides to allow the file to be drawn in; and a hydraulic jack coupled to the upper end of the reaction force support pipe and press-fitting the file.

In this case, the reaction force support pipe includes a main support pipe having a pipe shape and having openings on both sides, a reducing pipe having an inner diameter narrowed downwardly at a lower portion of the main supporting pipe, and a pipe shape at the lower part of the reducing pipe It may be made of a connecting pipe in which a female threaded part fastened to the male threaded part is formed on the inner circumferential surface.

And a connecting reinforcing bar may be formed protruding from the outer circumferential surface of the pile installation port so as to be connected to the reinforcing bar for the base slab that is reinforced on the base slab.

In addition, the hydraulic jack includes a reaction force plate fixed to seal the upper end of the reaction force support tube while being screwed to the upper end of the reaction force support tube, and a hydraulic cylinder coupled to the lower surface of the reaction force plate and installed downward in the reaction force support tube. can be included.

In addition, an extension sleeve tube may be further provided between the reaction force plate and the reaction force support tube to extend the length of the reaction force support tube.

The implant-type filing method using the implant-type pile press-fitting device in the building foundation system according to another embodiment of the present invention is made in a pipe shape so that a pile can be inserted, a male screw thread is formed at the upper end, and the upper and lower parts are A disposing step of arranging the pile installation holes each having an upper flange and a lower flange formed in the base slab forming space; Reinforcing reinforcement for the foundation slab in the foundation slab forming space, and a reinforcement step of bonding to the outer peripheral surface of the pile installation; A transplantation step of pouring and curing concrete in the reinforced foundation slab forming space, and burying and transplanting the pile installation port into the foundation slab; A reaction force support pipe formed in a pipe shape to accommodate a pile, a female threaded part is formed at the bottom, and is fastened with the male threaded part, and an opening is formed on both sides to allow the file to be drawn in, and the male threaded part of the pile installation part is fastened and a reaction force frame assembly step of installing a hydraulic jack on the upper end of the reaction force support pipe; a pile press-in step of inserting the pile through the opening of the reaction force support pipe and downwardly pressing the pile with the hydraulic jack; A fixing step of coupling the upper end of the press-fitted pile and the upper end of the pile installation tool; may be included.

Here, in the reinforcement step, the connecting reinforcing bars protruding from the outer circumferential surface of the pile installation port may be mutually joined with the reinforcing bars for the foundation slab reinforced in the foundation slab by welding or a coupler.

And between the reinforcement step and the transplanting step, the upper portion of the pile installation hole may further include a capping step of covering the pouring cover to prevent the exposure of the pile installation hole and the inflow of concrete to be poured.

According to the present invention made of the above configuration, since the implant-type pile installation tool is buried and transplanted in the foundation slab in advance when constructing a new structure, when forming a pile foundation or restoring deformation due to floating subsidence of a building and extension or There is no need to drill the foundation slab separately during remodeling. Therefore, since the reinforcing bars previously reinforced in the foundation slab are not cut, it is possible to prevent a decrease in strength without damaging the existing structure at all.

And since the buried and transplanted pile installation tool guides the verticality and straightness of the press-fitted pile, the verticality and straightness of the pile are guaranteed.

In addition, when only the pipe-shaped reaction force support tube is fastened to the pile installation hole, the reaction force support tube acts as a reaction force frame, so it is a very simple and fast pile press-in process compared to assembling the reaction force frame by assembling the reaction force frame by assembling the conventional rod-shaped reaction force ball and support body with a nut. can be performed.

In addition, since these implant-type pile installation tools and reaction force support pipes have a simple structure and are easy to mass-produce, the actual cost added at the time of new construction is very low compared to the total construction cost, so it is very effective.

In addition, since it has a simple structure, workers at the construction site can easily manufacture and install it according to the construction situation, which is very efficient.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

For reference, the description with reference to the drawings is for easier understanding of the present invention, and the scope of the present invention is not limited thereto. And, in describing the present invention, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

In the construction of a building foundation system, the present invention is to bury and transplant a pile installation hole in advance before pouring concrete on the foundation slab of a new structure, and then form a pile foundation or restore deformation due to floating settlement of a building and extension It relates to an implant-type pile press-in device that can press-in a pile by assembling a reaction force support pipe without the need for drilling in the foundation slab during remodeling and a filing method using the same.

First, an embodiment of the implant-type pile press-in device according to the present invention will be described with reference to FIGS. 2 to 5 . Figure 2 is a perspective view showing the exterior of the implant-type pile press-in device in the building foundation system according to an embodiment of the present invention, Figure 3 is a cross-sectional view of the present invention shown in Figure 2, Figure 4 is shown in Figure 2 It is an exploded cross-sectional view of the present invention, FIG. 5 is a perspective view showing another embodiment of the pile installation tool shown in FIG.

The implant-type pile press-in device according to the present invention may be configured to include a pile installation port 100 , a reaction force support pipe 300 , and a hydraulic jack 400 .

The pile installation port 100 is a steel pipe made of a pipe or cylinder shape. The cross-sectional shape of the pile installation port 100 may be circular or polygonal.

At this time, when the pile installation port 100 has a circular pipe shape, the inner diameter should be larger than the outer diameter of the pile to be press-fitted during expansion or modeling.

And the length of the pile installation port 100 should be the same as or shorter than the thickness of the foundation slab (S) to be expanded and contracted. This is because, buried in the foundation slab (S), it must be transplanted.

At this time, a male screw thread part 110 is formed on the upper outer peripheral surface of the pile installation port 100 . The male threaded part 110 is formed to be screw-coupled to a reaction force support pipe 300 to be described later.

In addition, an upper flange 140 and a lower flange 150 are coupled to the upper and lower portions of the pile installation port 100 , respectively.

The upper flange 140 and the lower flange 150 can prevent the pile installation port 100 from swinging while being mounted on the reinforcing bar during reinforcement of the foundation slab.

However, an upper portion of the pile installation hole 100 may be further provided with a pouring cover 200 having a detachable structure.

This blocks the inflow of concrete or foreign substances into the inside of the pile installation port 100 when pouring concrete for forming the foundation slab. In addition, after curing of the foundation slab (S) is completed, the pile installation port 100 is to prevent exposure to the outside in a buried and transplanted state.

The material of the pouring cover 200 may be a synthetic resin, but may be made of a steel material so as to be used instead of the reaction force plate 410 as will be described later.

Next, the reaction force support pipe 300 will be described.

The reaction force support pipe 300 is combined with the pile installation port 100 to allow the hydraulic jack 400 to be mounted, and is largely composed of a main support pipe 310 , a reduced pipe 320 and a connection pipe 330 . is composed

The main support pipe 310 is a steel pipe formed in the shape of a pipe or a cylinder. The cross section of the main support pipe 310 may be circular or polygonal, but a circular shape is preferable.

At this time, the inner diameter of the main support pipe 310 should be greater than the outer diameter of the pile (P) to be press-fitted. This is because the pile P and the hydraulic cylinder 420 must be accommodated inside the main support pipe 310 .

And, an opening 311 in a shape cut along the longitudinal direction is formed on one side of the main support pipe 310, and it is preferable that the openings 311 are formed on both sides.

The opening 311 may be formed to be elongated in the longitudinal direction to allow the file to be introduced into the inside of the main support pipe 310 from the outside, and the width may be appropriately formed.

However, if the width of the opening 311 is too large, the main support pipe 310 cannot support the reaction force, so the length and width of the opening 311 must be designed within the limit that can sufficiently support the reaction force.

In addition, a connection pipe 330 having a female threaded portion 331 formed on an inner circumferential surface is provided at a lower portion of the main support pipe 310 .

The connection pipe 330 is for fastening with the male screw thread part 110 of the pile installation port 100 .

However, the inner diameter of the connection pipe 330 has a length corresponding to the outer diameter of the pile installation port 100, but the main support pipe 310 has an outer diameter sufficient to support the reaction force after the opening 311 is formed. Therefore, it should be longer than the outer diameter of the connection pipe (330).

Accordingly, the reduction tube 320 is provided between the main support tube 310 and the connecting tube 330 to connect them. The reduction tube 320 is an inverted conical tube whose inner diameter becomes narrower toward the lower side.

When the connection pipe 330 is fastened to the pile installation port 100 , the reaction force support pipe 300 may be installed on the upper side of the pile installation port 100 .

Next, the hydraulic jack 400 will be described.

The hydraulic jack 400 is installed on the upper end of the reaction force support pipe 300 and press-fits the pile, and may be composed of a reaction force plate 410 and a hydraulic cylinder 420 .

The reaction plate is coupled to and fixed to the upper end of the main support tube 310 and may be a circular steel plate, and supports the hydraulic cylinder 420 while sealing the upper end of the main support tube 310 .

Specifically, the reaction plate 410 and the main support pipe 310 are preferably screw-coupled. That is, a female threaded part is also formed on the upper end of the main support pipe 310 , and a male threaded part 411 is formed on the lower end of the reaction force plate 410 to be coupled to each other. However, of course, they may be combined by welding or the like.

And the hydraulic cylinder 420 is coupled to the lower surface of the reaction force plate 410 and installed and accommodated in the downward direction in the main support pipe. That is, the body of the hydraulic cylinder 420 is supported by being coupled to the reaction plate 410, and the rod is disposed downward.

Here, the reaction plate 410 may be dedicated to the above-described pouring cover 200 .

That is, the hydraulic jack 400 is connected to the main support tube 300 by removing the pouring cover 200 and attaching the hydraulic cylinder 420 to the upper end of the main support tube 410 by bonding or fastening. ) can be combined at the top of the

Preferably, an extension sleeve tube 340 may be further included to extend the length of the reaction force support tube 300 between the reaction force plate 410 and the main support tube 310 . This can be assembled according to the field situation when the length of the press-fitted pile (P) is long.

The extended sleeve tube 340 has the same outer diameter as the main support tube 310 and may be fastened to the upper end of the main support tube 310 , and the reaction force plate 410 is disposed on the upper end of the extension sleeve tube 340 . It is possible to extend the length of the main support pipe 310 by fastening it.

Another embodiment of the present invention may have a structure in which one or more connecting reinforcing bars 130 are formed on the outer circumferential surface of the pile installation hole 100 as shown in FIG. 5 .

The connecting reinforcing bar 130 is for connecting the base slab reinforcing bar (B) and the pile installation tool (100) to be reinforced to form the base slab (S).

In order to facilitate the connection, the connecting reinforcing bar 130 should be formed so that the arrangement corresponds to the reinforcing bar (B) for the foundation slab to be reinforced.

In general, the reinforcing bar (B) for the foundation slab is reinforced with an upper reinforcing bar located at the upper portion and a lower reinforcing bar located at the lower portion. It can be pre-fabricated at the factory to be formed protruding into the

The connecting reinforcing bar 130 and the reinforcing bar (B) for the foundation slab may be joined by binding or welding by using a wire at the mutual intersection point.

Alternatively, a separate coupler (not shown) may be used to couple to each other.

For reference, if the connecting reinforcing bar 130 is not present, it can be joined by direct welding.

That is, it is possible to partially cut the reinforced reinforcement for the foundation slab (B) and join the pile installation port 100 by welding.

Hereinafter, with reference to Figs. 6a to 6e, another embodiment of the present invention, a filing method for press-fitting a pile using an implant-type pile press-in device will be described in detail.

Fig. 6a shows the reinforcement stage, Fig. 6b shows the transplantation stage, Fig. 6c shows the reaction frame assembly stage, Fig. 6d shows the press-in stage, and Fig. 6e is a construction process diagram showing the fixing stage.

First, the arrangement step is a step of installing the above-described pile installation hole 100 in the base slab forming space of the new structure.

Since the structure of the file installation port 100 is the same as described above, a detailed description thereof will be omitted.

Here, it may be disposed at any position of the foundation slab (S), but may be disposed radially around the reinforcing bars for columns erected generally vertically.

The following describes the rooting step.

Referring to the bar shown in Figure 6a, the reinforcement step is a step of reinforcing the reinforcing bar (B) for the foundation slab in the forming space of the foundation slab.

And it also includes the process of joining the reinforcement for the foundation slab (B) and the pile installation port (100).

The reinforcing bars (B) for the foundation slab may be arranged double in the upper and lower portions, and are arranged in a lattice form. In general, the spacing of the reinforcing bars (B) for each foundation slab is about 20 ~ 30cm.

At this time, reinforcement may be made so that the upper flange 140 and the lower flange 150 are mounted on the reinforcing bar.

If, the outer diameter of the pile installation port 100 is smaller than the interval between the reinforcing bars (B) for the foundation slab, there is no need to cut the reinforcing bars (B) for the foundation slab. However, if the outer diameter of the pile installation hole 100 is greater than the interval, part of the reinforcement for the foundation slab (B) to be reinforced is cut and the cut part is welded to the outer circumferential surface of the pile installation hole 100 to be joined.

Alternatively, as described above, the connecting rebar 70 and the cut portion may be connected with a wire or connected using welding or a coupler (not shown).

For reference, a capping step of covering the pouring cover 200 on the upper surface of the pile installation hole 100 may be further performed after the reinforcement step.

In order to cover the pouring cover 200, it can be capped by a method of fastening with the male thread part 110 of the pile installation port 100 or by simply closing a stopper. Due to this, it is possible to block the concrete poured in the next transplant step from flowing into the pile installation port 100, and when the foundation slab (S) is cured, it prevents the pile installation port 100 from being exposed to the outside. .

The next step is the transplantation step shown in FIG. 6B.

In the transplanting step, concrete is poured into the foundation slab forming space in which the reinforcing bars (B) for the foundation slab are reinforced, and the pile installation port 100 is placed in the foundation slab (S) while forming the foundation slab (S) by curing. This is the step to be buried.

At this time, the pouring concrete is poured so that the upper surface of the pouring cover 200 and the pouring surface coincide.

When the poured concrete is cured, the pile installation port 100 transplanted into the foundation slab (S) is buried until the expansion or remodeling is performed and when the pile foundation is formed later or when the deformation due to the immovable subsidence of the building is restored, remain transplanted.

Next is the reaction frame assembly step shown in Figure 6c. From this stage, the process for press-fitting the pile into the foundation slab (S) for actual extension or remodeling is performed.

The reaction force frame assembly step is a step of connecting the reaction force support pipe 300 described above with the pile installation port 100 and installing the hydraulic jack 400 on the upper end of the reaction force support tube 300 .

First, the pouring cover 200 is separated from the pile installation port 100 and disassembled.

And the connection pipe 330 of the reaction force support pipe 300 is fastened with the upper end of the pile installation port 100 to vertically install the reaction force support pipe 300 .

In addition, the hydraulic jack 400 is coupled to the upper end of the main support pipe 310 . That is, the reaction plate 410 is installed such that the main support pipe and the rod of the hydraulic cylinder 420 are downward.

The following is a press-in step of press-fitting the file into the hydraulic jack 400 as shown in FIG. 6d.

Specifically, in a state in which the pile P of a certain length is drawn through the opening 311 of the main support pipe 310 , the pile P is inserted into the pile installation port 100 .

Then, the upper end of the inserted file (P) is located below the hydraulic cylinder (420).

And when the hydraulic cylinder 420 is operated by supplying hydraulic pressure from the outside, the pile P is forcibly pressed into the ground below through the pile installation port 100 .

That is, by the reaction force of the reaction plate 410, the pile (P) is press-fitted to the lower side and goes down through the ground located below the foundation slab (S).

At this time, since the pile installation port 100 guides the straightness and the verticality of the pile (P), the straightness and the verticality are excellent compared to the existing ones.

It is natural that the file P can use all of various shapes. That is, if accommodated in the pile installation port 100, such as a steel pipe shape, an I-beam or H-beam shape, a steel bar shape, a polygonal pipe shape, it will be possible.

When the press-fitting of one file (P) is completed, another file (P) is again introduced through the opening 311, mounted on the top of the press-fitted file (P), and the contact portion of the two files (P) is welded to the pile A welding portion J may be formed. Then, the same press-fitting is performed by operating the hydraulic jack 200 again.

Alternatively, by forming a thread at the end of the pile (P), it is also possible to perform press-fitting after continuing to connect in a manner of screwing each other. That is, the pile may be extended in such a way that a female thread is formed in one of the piles, and a male thread is formed in the other pile to be mutually fastened.

On the other hand, it is preferable that the reaction plate 410 can be prepared separately, but the pouring cover 200 can be diverted in the present invention. That is, the material or standard of the pouring cover 200 is designed to be used as a reaction force plate, and while it is used as the pouring cover 200, it can be disassembled during extension or remodeling and used as the reaction force plate 410 .

As described above, since the foundation slab is drilled in advance by the pile installation port 100, there is an advantage that there is no need to drill a hole in the foundation slab (S) of the structure and cut the reinforcing bar as in the prior art.

In addition, since the reaction force support tube 300 itself functions like a plurality of conventional reaction force support rods, there is no need to assemble the reaction force frame by cumbersomely fastening the reaction force support rod with a nut.

Next, the fixing step is a step of integrating the upper end of the last press-fitted file (P) and the upper end of the file installation port 100 when the press-fitting of the file is completed as shown in FIG. 6e.

That is, by combining the press-fitted pile (P) with the pile installation port (100), the pile (P) press-fitted into the lower ground can support the entire foundation slab (S) even after excavation of the ground.

The pile installation port 100 and the pile (P) may be coupled to each other by welding.

Due to this structure, the press-fitted pile (P) can more firmly support the load of the foundation slab (S).

Although a representative embodiment of the present invention has been described above with reference to the drawings, those skilled in the art to which the present invention pertains will be able to make various applications and modifications within the scope of the present invention based on the above content.
