Description

Longitudinal and transverse integrated structure of piles and structures manufactured using the same {LONGITUDINAL AND LATERAL INTEGRATION STRUCTURE OF PILE AND STRUCTURE MANUFACTURED USING THE SAME}

The present invention relates to a structure that integrates the longitudinal and transverse directions of piles. More specifically, after constructing the pile underground or on the ground, when connecting the top plate, middle plate, and bottom plate to the pile, the longitudinal and transverse directions of the pile are structurally integrated to enable more stable structure construction. This relates to transverse integrated structures and structures manufactured using them.

In order to construct an underground structure such as an underground roadway, a column-type wall using steel pipes is first constructed so that the piles are adjacent to each other in the ground.

After excavating the ground between the main thermal walls penetrated into the ground by pre-constructed piles to expose the pre-constructed main thermal walls,

It is constructed in a way that completes the underground structure by connecting a concrete structure (C) such as a top plate, middle floor plate, or bottom plate between the exposed column-type walls.

Figure 1a is a construction example of a conventional column-type wall constructed continuously below the ground.

According to Figure 1a, it can be seen that the main heated wall is being constructed by constructing the steel pipes 11 adjacent to each other in the longitudinal direction, and a support bracket 12 in the form of a vertical plate is installed on the exposed surface of the main heated wall,

After ensuring that the top deck 14 is supported on the support bracket 12,

The deck integration reinforcement (13) is placed from the inside of the steel pipe to the top of the deck for the deck, and concrete is poured to structurally integrate the main row wall (10) and the deck (14) formed adjacent to each other by the steel pipe (11). Able to know.

At this time, this structural integration ensures that the deck integrated reinforcement bars (14) extending from the inside of the steel pipe to the top of the deck for the deck are reinforced, and the steel pipes (11) and the deck for the deck (14) are made continuous with each other by pouring concrete (C). It will come true,

For this work, it can be seen that the upper part of the main heat-type wall 10 has a trench space S for work formed partially outside the upper part of the main-heat wall 10.

However, this excavation space (S) requires additional temporary facilities (not shown) such as earth retaining walls, and if the construction site becomes narrow, not only does it become difficult to construct temporary facilities, but it also inevitably interferes with surrounding traffic, making it difficult to apply the construction method. Problems arise that make it impossible.

In order to solve this problem, in the case of Figure 1a, it can be seen that a form wall 15 made of concrete is installed separately in place of the temporary facility.

Figure 1b is another construction example of a conventional column-type wall constructed continuously below the ground.

Above, Figure 1b also shows that after continuously constructing the main heated wall using the steel pipe 11, when constructing the middle plate rather than the upper part of the main heated wall, miscellaneous metals (40:41, 42, 43, 44) You can see that it is being used.

In other words, the exposed steel pipes of the column-type wall have a curved outer peripheral surface, and it can be seen that the bent steel bracket 41 is used to extend the horizontal connecting reinforcing bar horizontally on the outer peripheral surface of the steel pipe. By pouring concrete, It can be seen that the middle floor plate is integrated with the main heated wall.

However, since the horizontal connecting rebar must be constructed by welding to the steel pipes, and the steel bracket 41 must also be constructed by welding on the outer peripheral surface of the steel pipe 11, it can be seen that there is a problem of poor constructability and workability.

Figure 1c is another construction example of a conventional column-type wall constructed continuously below the ground.

In other words, when a steel pipe is used as a main-heated wall, a connecting bracket is installed to enable the bottom plate to be constructed by welding.

Accordingly, the connecting bracket can be used to construct the bottom plate of an underground structure by welding the horizontal connecting reinforcing bar and the bottom plate reinforcing bar (16) extending horizontally to the fastening brackets (17, 18) manufactured to surround the bottom of the column-type wall. You can see that this is possible.

In the end, when constructing a conventional main-heated wall using steel pipes, in order to integrate the top plate, middle floor plate, and bottom plate with the main-heated wall, the middle floor plate and bottom plate are equipped with connecting brackets (17, 18, 40) and horizontal connecting reinforcing bars. You can see that it is installed separately,

In the case of the top plate, if it is possible to secure the tupperware space, it can be seen that the method of installing the top plate integrated rebar (13) from a steel pipe can be used.

In order to reinforce the top plate integrated reinforcement (13), the excavation space (S) must be secured at the top of the main row wall,

If it is impossible to secure the excavation space (S), there is virtually no choice but to adopt a method of installing horizontal connecting reinforcing bars using means such as connecting brackets (17, 18, 40) that are the same as the middle floor plate and bottom plate. However, since the installation work of these connecting brackets (17, 18, 40) and the construction work of the steel pipe or concrete pile (11) were performed separately, there was a problem that workability was significantly reduced.

Accordingly, in the present invention, after constructing piles on the ground and the ground, structurally integrating the top plate with the pile makes it possible to structurally integrate the pile and the top plate without any digging work at the top or bottom of the pile, so it is possible to construct more quickly and The technical task is to provide a structure that integrates the longitudinal and transverse directions of piles that can be economically constructed and a structure manufactured using the same.

In addition, in the present invention, after pre-construction of the pile, the middle floor plate and the bottom plate are structurally integrated into each pile, and the construction is not simply carried out so that they are supported by the connection brackets, but the middle floor plate and the bottom plate are structurally integrated with the pile like a top plate. By making construction possible, it is a technical problem to solve the provision of an integrated structure in the longitudinal and transverse directions of the pile and a structure manufactured using it.

It is connected to any one of reinforcing bars, connecting reinforcing bars for middle plates, and connecting reinforcing bars for bottom plates, so that the pile, top plate, middle plate, or bottom plate are integrated in the longitudinal direction by concrete pouring and curing, and the inside of the opening and the transverse reinforcing bar assembly are The poured concrete is cured to be buried, so that one of the top plate, middle plate, or bottom plate of the structure and the pile are integrated in the transverse direction by the transverse reinforcing bar assembly embedded in the concrete.

In addition, the structure manufactured using the longitudinal and transverse integrated structure of the pile of the present invention for achieving the above problem includes a pile constructed by penetrating and installing a hollow pile with a sealed opening formed on the ground or underground; A transverse reinforcing bar assembly installed to extend laterally in the exposed opening by removing the sealed opening, and including a rectangular parallelepiped-shaped reinforcing bar assembly arranged in the transverse direction by seating it so as to continuously pass through the transversely exposed openings; Concrete poured and cured so that the inside of the opening and the transverse reinforcing bar assembly are buried; And connecting the exposed built-in connecting reinforcing bar by removing the cover formed to seal the opening of the pile with any one of the connecting reinforcing bars for the upper plate, the connecting reinforcing plate for the middle plate, and the connecting reinforcing bar for the bottom plate, and the pile and Including a top plate, middle plate, or bottom plate integrated in the longitudinal direction, any one of the top plate, middle plate, or bottom plate and the pile are integrated in the transverse direction by a transverse reinforcing bar assembly, and the top plate, middle plate, or bottom plate Any one of the above piles is constructed to be integrated in the longitudinal direction by connecting reinforcing bars for the upper plate, connecting reinforcing bars for the middle plate, and connecting reinforcing bars for the bottom plate.

According to the present invention, after construction using piles including a column-type wall in the ground and a pile structure on the ground, the upper plate, middle plate, and bottom plate can be structurally integrated in the inner excavation space (S2) and on the ground. As there is no need to install separate temporary facilities at the top or bottom of the pile, it is possible to provide a very quick, efficient and economical integrated structure of the longitudinal and lateral directions of the pile and a structure manufactured using it.

These piles 110 are constructed by inserting or self-supporting a plurality of hollow piles 111 into the ground (G).

At this time, in the case of underground structures (underpass, underground tunnel, etc.), the pile 110 is constructed so that the head of the pile 110 is exposed,

In the case of ground structures (ground structures for logistics centers, etc.), the lower ends of the piles 110 are penetrated and the piles 110 are exposed to the ground.

At this time, each hollow pile 111 has openings 112 (112a, 112b, 112c) formed in advance at the areas where the top plate 120, the middle plate 130, and the bottom plate 140 must be connected. (112) Forming a built-in connecting rebar (113) inside,

After closing the opening 112 using the cover 114,

A method of penetrating or self-supporting the excavated ground or ground is used.

That is, the construction of the pile 110 is completed by penetrating into the ground or installing a cover 114 on the ground so that the built-in connecting reinforcing bar 113 of the opening 112 is not exposed,

At the stage of connecting the top plate 120, middle plate 130, and bottom plate 140, the cover 114 is removed to expose the built-in connecting reinforcing bar 113,

A method of connecting the connecting reinforcing bars (121, 131, 141) and transverse reinforcing bar assemblies (122, 132, 142) for the top, middle, and bottom plates arranged in the transverse and longitudinal directions with the inner excavation space (S2) and the built-in connecting reinforcing bars (113) exposed on the ground. By constructing with

The upper plate 120, the middle plate 130, and the lower plate 140 can be integrated into the pile 110 without a separate excavation space (S) as shown in Figure 1a at the top or bottom of the pile 110. It will be so.

That is, in the present invention, work for constructing the excavation space (S) at the top and bottom of the pile for integrated construction with the top plate 120, middle plate 130, and bottom plate 140 can be excluded,

The pile 110, the top plate 120, the middle plate 130, and the bottom plate 140 are composed of built-in connecting reinforcing bars 113 exposed from the pile 110 and connecting reinforcing bars 121, 131, 141 for the upper plate, middle plate, and bottom plate, in the transverse direction. Using a method of connecting the reinforcing bar assemblies (122, 132, 142) to each other and then structurally integrating them by pouring concrete,

The top plate 120, the middle plate 130, and the bottom plate 140 can be structurally integrated into the pile 110 in the longitudinal and transverse directions.

Accordingly, according to FIGS. 2A and 2B, it can be confirmed that the pile 110 and the upper plate 120 of the present invention are integrated in the longitudinal and transverse directions.

At this time, for convenience, the pile 110 will be examined based on the case where it is installed in the ground to construct an underground structure as the structure 100.

First, referring to FIG. 5A, the pile 110 penetrates the ground (G) by adjacent to each other hollow piles (111) including steel pipes, and the adjacent hollow piles (111) penetrate the ground (G) between the piles (110). By installing a waterproof connection plate 115 between the exposed outer peripheral surfaces of the hollow piles 111 penetrated while excavating downward from the ground, continuity and waterproofness in the transverse direction can be secured.

In addition, the hollow pile 111 must be connected to the upper plate 120 in advance before penetration, so that the outer peripheral surface is cut in a certain area up and down in consideration of the outer peripheral surface area, and then, referring to Figure 2b, the built-in connecting reinforcing bar 113 can be connected from the outside. ) is installed on the inner side of the steel pipe in advance using methods such as welding.

Accordingly, referring to FIGS. 2A and 2B, the opening 112a for the upper plate formed by the incision is inevitably a vulnerable structure, so a reinforcing plate in the form of a vertical plate ( 116) is additionally installed on the inner side of the steel pipe.

In addition, when penetrating the hollow pile 111 into the excavated ground, soil, etc. may flow into the opening 112a for the top plate, so the cover 114 is installed by welding to seal the opening 112a for the top plate.

Referring to FIG. 5A, the cover 114 is removed to expose the built-in connecting reinforcing bar 113 and the reinforcing plate 116 by removing the welded portion after forming the inner excavation space S2.

Accordingly, referring to FIG. 2b, the built-in connecting reinforcing bar 113 exposed by removing the cover 114 is connected to the connecting reinforcing bar 121 for the upper plate.

At this time, the connecting reinforcing bar 121 for the upper plate can be connected longitudinally at the site by the built-in connecting reinforcing bar 113 and a coupler, etc., and is arranged to extend to the upper part of the upper deck deck 123 using the inner excavation space (S2). Just do it.

In addition, it can be seen that the transverse reinforcing bar assembly 122, which can be formed continuously in the transverse direction, is used.

Referring to FIG. 2A, it can be seen that the transverse reinforcing bar assembly 122 is a rectangular rectangular reinforcing bar assembly and is arranged in the transverse direction by successively passing through the openings 112a for the upper plate exposed in the transverse direction.

Referring to FIG. 2b, the deck extension reinforcing bar 124 is connected to the transverse reinforcing bar assembly ( 122) It is positioned and connected to extend inward.

The exposed built-in connecting reinforcing bar 113 is connected to the connecting reinforcing bar 121 for the upper plate so that the upper plate 120 is connected in the longitudinal direction,

In a state in which the transverse reinforcing bar assembly 122 and the deck extension rebar 124 seated and placed in the openings 112a for the upper plate are connected to successively pass through the openings 112a for the horizontally exposed upper plate,

The top plate concrete (C1) is inserted into the top plate opening (112a) so that the built-in connecting reinforcing bar (113), reinforcing plate (116), top connecting reinforcing bar (121), transverse reinforcing bar assembly (122), and deck extension reinforcing bar (124) are embedded. It can be seen that the piles 110 and the top plate 120 are continuously and structurally integrated in the longitudinal and transverse directions by pouring and curing the top deck 123 to a certain thickness inside.

Next, according to FIGS. 3A and 3B, it can be seen that the pile 110 and the intermediate plate 130 of the present invention are integrated in the longitudinal and transverse directions.

Also, for convenience, the pile 110 will be examined based on the case where it is installed in the ground to construct an underground structure as the structure 100.

The vertical and horizontal integration structure of the pile 110 and the middle plate 130 is constructed in the same manner as the longitudinal and horizontal integration structure of the pile 110 and the upper plate 120, except that the construction location is the pile ( 110), it only corresponds to the middle region.

Accordingly, referring to FIG. 5b, after the upper plate 120 and the pile 110 are structurally integrated, the inner excavation space S2 is further formed downward through additional excavation,

Accordingly, the outer peripheral surface of the middle portion of the pile 110 is exposed, and an opening 112b for the middle plate previously sealed by the cover 114 is also exposed in this middle portion, and the middle plate 130 is opened using the opening 112b for the middle plate. ) is structurally integrated.

In other words, the hollow pile 111 must be connected to the middle plate 130 in advance before penetration in order to form an opening 112a for the upper plate, and then cut the outer peripheral surface up and down in consideration of the inner surface area and then connect it from the outside. The opening 112b for the intermediate plate is formed by installing the built-in connecting reinforcing bar 113 on the inner side of the steel pipe in advance by welding or the like.

Accordingly, referring to FIG. 3b, since the opening 112b for the middle plate formed by the incision is inevitably a vulnerable structure, a reinforcing plate 116 in the form of a vertical plate is installed so that the built-in connecting reinforcing bars 113 can be located in between. is also installed on the inner side of the steel pipe.

In addition, when penetrating the hollow pile 111 into the excavated ground, soil, etc. may flow into the opening 112b for the middle plate, so the cover 114 is installed by welding or the like to seal the opening 112b for the middle plate. do.

This cover 114 is identical in that when the inner excavation space S2 is formed by additional excavation, the welded portion is removed to expose the built-in connecting reinforcing bar 113 and the reinforcing plate 116.

Accordingly, referring to FIG. 3b, the built-in connecting reinforcing bar 113 exposed by removing the cover 114 is connected to the connecting reinforcing bar 131 for the middle plate.

At this time, the connecting reinforcing bar 131 for the middle plate can be connected longitudinally at the site by the built-in connecting reinforcing bar 113 and a coupler, etc., and the upper part of the deck 133 for the middle plate is used using the inner excavation space (S2) by additional excavation. All you have to do is extend it to .

In addition, referring to FIGS. 3A and 3B, it can be seen that the transverse reinforcing bar assembly 132, which can be formed continuously in the transverse direction, is used.

It can be seen that this transverse reinforcing bar assembly 132 is also a rectangular-shaped reinforcing bar assembly and is arranged in the transverse direction by continuously seating the openings 112b for the intermediate plate exposed in the transverse direction.

Deck extension reinforcing bars 134 are inserted from the deck 133 for the intermediate plate, which is mounted on the hollow pile 111 and the support bracket 117 formed to be exposed below the opening 112b for the intermediate plate, to the inside of the transverse reinforcing bar assembly 132. The positioning to extend and connect is the same.

The exposed built-in connecting reinforcing bar 113 is connected to the connecting reinforcing bar 131 for the middle plate so that the middle plate 130 is connected in the longitudinal direction,

In a state in which the transverse reinforcing bar assembly 132 and the deck extension rebar 134 seated and arranged in the mid-plate openings 112b are connected to successively pass through the laterally exposed mid-plate openings 112b,

The middle plate concrete (C2) is inserted into the middle plate opening (112b) so that the built-in connecting reinforcing bar (113), reinforcing plate (116), connecting reinforcing bar (131) for the middle plate, transverse reinforcing bar assembly (132), and deck extension reinforcing bar (134) are embedded. ) It can be seen that the pile 110 and the middle plate 130 are continuously and structurally integrated in the longitudinal and transverse directions by pouring and curing the inner, upper part of the middle plate deck 133 to a certain thickness.

Next, according to FIGS. 4A and 4B, it can be seen that the pile 110 and the bottom plate 140 of the present invention are integrated in the longitudinal and transverse directions.

Also, for convenience, the pile 110 will be examined based on the case where it is installed in the ground to construct an underground structure as the structure 100.

The vertical and horizontal integration structure with the pile 110 and the bottom plate 140 is constructed in the same manner as the longitudinal and transverse integration structure with the pile 110, the upper plate 120, and the middle plate 130, and only The construction location only corresponds to the lower part based on the pile 110.

Accordingly, referring to FIG. 5C, after the upper plate 120, the middle plate 130, and the pile 110 are structurally integrated moving downward from the top, the inner excavation space S2 is further excavated downward through additional excavation. It is completed above rather than at the tip of the pile 110.

Accordingly, the outer peripheral surface of the lower part of the pile 110 is exposed, and an opening 112c for the bottom plate previously sealed by the cover 114 is exposed at this lower part, and the bottom plate 140 is opened using this opening 112c for the bottom plate. It is structurally integrated.

That is, the hollow pile 111 must be connected to the bottom plate 140 in advance before penetration in addition to forming an opening 112a for the upper plate and an opening 112b for the middle plate, so that the sides are also cut up and down in consideration of the outer peripheral surface area. Afterwards, an opening 112c for the bottom plate is formed so that it can be connected from the outside, and the built-in connecting reinforcing bar 113 is installed in advance on the inner side of the steel pipe by a method such as welding.

Accordingly, referring to FIG. 4b, the bottom plate opening 112c formed by the incision is inevitably a vulnerable structure, so a reinforcement plate 116 in the form of a vertical plate is installed so that the built-in connecting reinforcing bars 113 can be located between them. is also installed on the inner side of the steel pipe.

In addition, when the hollow pile 111 penetrates the excavated ground, soil, etc. may flow into the bottom plate opening 112c, so the cover 114 is installed by welding or the like to seal the bottom plate opening 112c. do.

This cover 114 is identical in that when the inner excavation space S2 is formed through additional excavation, the welded portion is removed to expose the built-in connecting reinforcing bar 113 and the reinforcing plate 116.

Accordingly, referring to FIG. 4b, the built-in connecting reinforcing bar 113 exposed by removing the cover 114 is connected to the connecting reinforcing bar 141 for the bottom plate.

At this time, the connecting reinforcing bar 141 for the bottom plate can be connected longitudinally at the site by the built-in connecting reinforcing bar 113 and a coupler, etc., and is arranged to extend inside the upper part of the bottom plate 140 using the inner excavation space (S2). do.

In addition, it can be seen that the transverse reinforcing bar assembly 142, which can be formed continuously in the transverse direction, is used.

It can be seen that this transverse reinforcing bar assembly 142 is also a rectangular rectangular reinforcing bar assembly and is arranged in the transverse direction by continuously seating the openings 112c for the bottom plate exposed in the transverse direction.

In addition, it is the same that the connecting reinforcing bar 141 for the bottom plate is positioned to extend and connect to the inside of the transverse reinforcing bar assembly 142,

The exposed built-in connecting reinforcing bar 113 is connected to the connecting reinforcing bar 141 for the bottom plate so that the bottom plate 140 is connected in the longitudinal direction,

In a state in which the transverse reinforcing bar assembly 142 seated in the bottom plate opening 112c is connected to successively pass through the laterally exposed bottom plate openings 112c,

The bottom plate concrete (C3) is formed to a certain thickness including the inside of the opening (112c) for the bottom plate so that the built-in connecting reinforcing bar (113), the reinforcing plate (116), the connecting reinforcing bar (141) for the bottom plate, and the transverse reinforcing bar assembly (142) are embedded. It can be seen that the pile 110 and the base plate 140 are continuously placed and cured in the longitudinal and transverse directions to be structurally integrated.

In this way, it can be seen that a deck is not used when constructing the bottom plate 140, unlike the top plate 120 and the middle plate 130, but there is no problem in using a deck for the bottom plate (not shown) if necessary.

In addition, in the case of a ground structure (not shown), the lower end of the pile 110 is penetrated into the ground (G), the cover 114 of the sealed opening 112 of the pile 110 exposed on the ground is removed, and the The built-in connecting reinforcing bar (113) is exposed, and the built-in connecting reinforcing bar (113) and the bottom plate connecting reinforcing bar (141) are connected in the longitudinal direction,

Also, after installing the transverse reinforcing bar assembly 142 horizontally in the opening 112 continuously on the ground, the top plate, middle plate, and bottom plate concrete (C1, C2, C3) are installed to a certain thickness including the inside of the opening 112. Again, pouring and curing may be performed so that the pile 110 and the base plate 140 are structurally integrated in a continuous manner in the longitudinal and transverse directions.

[Structure 100 manufactured using the longitudinal and transverse integrated structure of the pile 110 of the present invention]

Also, for convenience, the pile 110 will be examined based on the case where it is installed in the ground to construct an underground structure as the structure 100.

Figures 5a, 5b and 5c show examples of the construction process of the structure 100 manufactured using the longitudinal and transverse integrated structure of the pile 110 of the present invention.

Referring to FIGS. 5A, 5B, and 5C, the structure 100 manufactured using the longitudinal and transverse integrated structure of the pile 110 includes, for example, an opening 112a for the upper plate and an opening 112a for the middle plate in the hollow pile 111. The opening 112b and the bottom plate opening 112c are sealed with a cover 114,

On the inner surface of the hollow pile 111 in the area where the opening 112a for the top plate, the opening 112b for the middle plate, and the opening 112c for the bottom plate are formed, the built-in connecting rebar 113 and reinforcement that are not exposed by the cover 114 are provided. The plate 116 is formed.

Accordingly, the hollow pile 111 in which the non-exposed built-in connecting rebar 113 and the reinforcement plate 116 are sealed by the cover 114 is constructed as a pile 110 on the ground (G),

When the opening 112a for the upper plate is exposed in the inner excavation space S2 while excavating the ground G between the piles 110 downward from the ground, the cover 114 is removed, and the upper plate 120 is installed into the pile 110. ) and are structurally integrated in the longitudinal and transverse directions,

Additionally, when the opening 112b for the middle plate is exposed in the inner excavation space S2 while excavating the ground G downward, the cover 114 is removed, and the middle plate 130 is connected to the pile 110 in the longitudinal and transverse directions. Structurally integrated in the direction,
