Description

TECHNICAL FIELD

[0001] The present invention relates to a connection structure and a connection method for precast concrete panel members.

BACKGROUND ART

[0002] In general, the structure of a quay constructed on a coast or riverbank is composed of a revetment section for the purpose of preventing erosion and retaining earth at locations that come into direct contact with seawater or river water, and a land slab section that is located on the land side of the revetment section and has a flat surface on which various operations are performed. In recent years, land slab sections have tended to be subjected to greater excessive loads than in the past, such as for mooring large vessels and loading and unloading heavy goods. However, as shown in Fig. 7(a), although the land slab section 100 itself is made of reinforced concrete with reinforcing bars embedded inside, its lower portion is mounted on soil 101 with low load-bearing capacity, and the load-bearing performance of the land slab section 100 has its limits. Accordingly, for the purpose of reinforcing the land slab section 100 using the sheet pile wall 102 as shown in Fig. 7(b), in recent years, the coping section 103 at the head of the sheet pile wall 102 and the land slab section 100 have been integrally manufactured using cast-in-place concrete. However, this on-site concrete casting work has a problem of involving particularly difficult operations at the waterside, such as formwork installation, and a solution to this problem has been desired.

[0003] Here, Patent Document 1 discloses a quay structure in which a height adjustment plate is placed on a height adjustment jig welded to the upper portion of a steel pipe sheet pile, and a precast coping concrete block having a U-shaped cross section is fixed. This quay structure is configured such that the inner surface of the U-shaped coping concrete block and the outer surface of the steel pipe sheet pile are connected by a turnbuckle to adjust the gap between the two members.

[0004] Further, Patent Document 2 discloses a structure in which a connector is attached to the upper edge of a sheet pile, and a coping concrete block is installed with a separator.

[0006] However, with conventional quay wall structures, it was not easy to adjust the position of the precast concrete panel materials that were connected to the sheet pile wall.

[0007] In view of the above circumstances, the present invention aims to provide a means for easily adjusting the position of precast concrete panel materials in a structure that connects precast concrete panel materials to a sheet pile wall. [Means for solving the problem]

[0008] To achieve the above objective, the present invention provides a panel material connecting structure for connecting precast concrete panel material to a sheet pile wall consisting of a plurality of sheet piles arranged in a continuous manner, comprising a first truss member and a second truss member connecting the sheet piles and the panel material, cast-in-place concrete filling the gap between the sheet pile wall and the panel material, and the first truss member and the second truss member each being provided with length adjustment means.

[0009] In this connecting structure, a first connecting fitting may be attached to the sheet pile, a second connecting fitting may be attached to the panel material, and the second connecting fitting may be placed on the first connecting fitting.

[0010] Furthermore, according to the present invention, a method for connecting the sheet pile wall and the panel material using the above-described connecting structure is provided, characterized in that the panel material is positioned to the side of the sheet pile wall by placing the second connecting fitting on the first connecting fitting, and the lengths of the first truss member and the second truss member are adjusted, respectively.

[0011] In this connection method, the installation height of the panel material may be finely adjusted by inserting a shim between the first connecting fitting and the second connecting fitting, and the distance between the sheet pile and the panel material may be finely adjusted by rotating a bolt interposed between the first connecting fitting and the second connecting fitting. [Effects of the Invention]

[0012] According to the present invention, in a structure for connecting precast concrete panel materials to a sheet pile wall, the position of the panel materials can be easily adjusted by operating length adjustment means provided on the first truss member and the second truss member.

[Figure 4] This is a bottom view (viewed from below) of position III in Figure 1. [Figure 5] This is an explanatory diagram of a half-precast quay wall structure equipped with a connecting structure according to an embodiment of the present invention, having a first connecting fitting and a second connecting fitting. [Figure 6] Figure 5 is an enlarged view of the main part. [Figure 7] This is an explanatory diagram of the conventional technology. [Modes for carrying out the invention]

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification and the drawings, components having substantially the same functional configuration may be assigned the same reference numerals to omit redundant description. Further, in Figs. 1 to 6, the X direction indicates the horizontal distance direction between the sheet pile wall 11 (sheet pile 10) and the panel member 15, the Y direction indicates the direction in which the plurality of sheet piles 10 are arranged (the direction in which the quay is continuous, the sheet pile wall 11 extends, and the width direction of the panel member 15), and the Z direction indicates the vertical direction.

[0015] As shown in Figs. 1 to 4, the half-precast quay structure 1 provided with the connection structure 4 according to the embodiment of the present invention is a structure for the purpose of preventing erosion of the quay 2 and retaining earth, and consists of a half-precast revetment section A and a land slab B installed on the land side of the revetment section A. In Fig. 1, the boundary between the revetment section A and the land slab B is indicated by a broken line, but as will be described later, the two are integrally manufactured, and the broken line is a virtual boundary for explanation. The revetment section A has a sheet pile wall 11 composed of a plurality of sheet piles 10 arranged continuously along the longitudinal direction (Y direction) of the quay 2. The lower part of each sheet pile 10 is driven into the seabed, and the head part protrudes from the ground. In the illustrated example, the sheet piles 10 are steel pipe piles, and adjacent sheet piles 10 are connected to each other without gaps by joints 12. The surface of the quay 2 is covered with the land slab B.

[0016] The revetment section A further includes a panel member 15 and a coping section 40, and on the sea side of the sheet pile wall 11, a precast concrete panel member 15 connected to the sheet pile wall 11 by the connection structure 4 according to the embodiment of the present invention is arranged. The panel member 15 is arranged to extend from a position higher than the upper end (head) of the sheet pile 10 to a position lower than the upper end (head) of the sheet pile 10. By covering the sea side of the head of the sheet pile wall 11 with the panel member 15, corrosion of the sheet pile wall 11 in the intertidal zone and splash zone is prevented. In Figs. 1 to 4, the left side in the X direction is the sea side, and the right side is the land side.

[0017] A connecting fitting 20 is attached to the upper end of the sheet pile 10, and the land-side surface of the panel material 15 is connected to this connecting fitting 20 by a connecting structure 4 consisting of a first truss member 21 and a second truss member 22. The first truss member 21 connects the upper end (upper part) of the sheet pile 10 to the area near the upper end (upper part) of the panel material 15. The second truss member 22 connects the upper end (upper part) of the sheet pile 10 to the area near the lower end (lower part) of the panel material 15. These first truss member 21 and second truss member 22 are each equipped with turnbuckles 23 and 24 as means for adjusting their length. In addition, the sheet pile 10 and the panel material 15 are also connected by horizontal bolts 25, and the sheet pile 10 and the panel material 15 are fixed to each other by washers 26 and bolts 27 attached to both ends of the horizontal bolts 25. The first truss member 21 and the second truss member 22 are connected to the landward surface of the panel material 15 by appropriate brackets 28.

[0018] The height (Z direction) of the panel material 15 relative to the sheet pile wall 11 (sheet pile pile 10), and the horizontal distance (X direction) from the sheet pile wall 11 (sheet pile pile 10) to the panel material 15, can be adjusted to the desired size by operating the turnbuckle 23 attached to the first truss member 21 and the turnbuckle 24 attached to the second truss member 22. Furthermore, the twist angle of the panel material 15 around the Y axis can also be adjusted by operating the turnbuckles 23 and 24. This allows the panel material 15 to be positioned vertically at the desired height (Z direction) and distance (X direction) on the seaward side of the sheet pile wall 11. The panel material 15, positioned vertically at the desired height (Z direction) and distance (X direction), can then be fixed in place by washers 26 and bolts 27 attached to both ends of the horizontal bolt 25.

[0019] The panel member 15 has connecting rebars 30 that protrude horizontally (in the X direction) from the upper part of the panel member 15 toward the land side. The proximal end portion 30a of the connecting rebar 30 is embedded inside the panel member 15 when the panel member 15 is manufactured from precast concrete. The other end side of the connecting rebar 30 is provided to protrude horizontally (in the X direction) from the upper part of the panel member 15 toward the land side. The connecting rebar 30 is made of, for example, a deformed rebar in order to enhance the adhesion between the panel member 15, the coping section 40 described later, and the land-side slab B.

[0020] The other end side of the connecting rebar 30 protruding from the panel member 15 is composed of a panel member side portion 30b protruding from the land-side surface of the panel member 15, and a land-side slab portion 30c embedded in the land-side slab B. The proximal end portion 30a, the panel member side portion 30b and the land-side slab portion 30c may be formed integrally, or may be connected to each other by a joint 30d at an arbitrary position.

[0021] Further, a formwork 31 is attached to the bottom surface of the panel member 15 attached to the sea side of the sheet pile wall 11. The formwork 31 is formed by molding, for example, a plywood material or the like into a desired shape (a shape conforming to the outer surface of the sheet pile wall 11) at the bottom surface of the panel member 15 so as to fill the gap between the inner surface of the panel member 15 (the land-side inner surface of the panel member 15) and the outer surface of the sheet pile wall 11 (the sea-side outer surface of the sheet pile wall 11). The formwork 31 is mounted on the bottom surface of the panel member 15 via a slide-type hardware 32, and moves in the horizontal direction (X direction) to close the gap between the inner surface of the panel member 15 and the outer surface of the sheet pile wall 11 without any space. Note that the formwork 31 prevents leakage of liquid concrete, and may be removed after the concrete is solidified.

[0022] The landward side of the panel material 15 is filled with a coping section 40 made of cast-in-place concrete that has been filled and hardened. The coping section 40 is positioned on the landward side of the panel material 15 with the heads of the sheet piles 10 and connecting reinforcing bars 30 embedded in it, and the half-precast quay wall structure 1 is integrally constructed over the entire quay wall 2 covered by the land slab B. The coping section 40 consists of cast-in-place concrete that fills the gap between the panel material 15 and the land slab B (including the gap between the panel material 15 and the sheet pile wall 11) and the upper part of the sheet pile wall 11 and the area around its heads.

[0023] As shown in this embodiment, multiple hoop reinforcements 16 and wire mesh reinforcements 17 may be attached to the landward surface of the panel material 15. The hoop reinforcements 16 and wire mesh reinforcements 17 improve the adhesion between the precast panel material 15 and the cast-in-place concrete (coping section 40) described later, and prevent displacement at the interface.

[0024] When constructing such a half-precast quay wall structure 1, first, multiple sheet piles 10 are arranged in a continuous line along the quay wall 2 to form a sheet pile wall 11 (sheet pile wall formation process). In this case, the lower part of each sheet pile 10 is driven into the seabed, and the top part protrudes from the ground. In addition, adjacent sheet piles 10 are connected without gaps by joints 12, and the seaward side of the quay wall 2 is surrounded by the sheet pile wall 11.

[0025] Next, the panel material 15 is placed on the seaward side of the sheet pile wall 11, and the panel material 15 is connected to the sheet pile wall 11 by the connecting structure 4 (panel material placement process). In this case, the connecting hardware 20 attached to the upper end of the sheet pile 10 and the landward surface of the panel material 15 are connected by the first truss member 21 and the second truss member 22. Then, by operating the respective turnbuckles 23 and 24, the panel material 15 is positioned vertically on the seaward side of the sheet pile wall 11 at a desired height (Z direction) and distance (X direction). The panel material 15, positioned vertically at the desired height (Z direction) and distance (X direction), is then fixed by washers 26 and bolts 27 attached to both ends of the horizontal bolt 25.

[0026] Furthermore, by arranging the panel material 15 on the seaward side of the sheet pile wall 11 in this manner, the connecting reinforcing bars 30 protrude horizontally (in the X direction) from the top of the panel material 15 toward the landward side, and the connecting reinforcing bars 30 extend into the interior of the land slab B. The connecting reinforcing bars 30 may also be connected to the reinforcement structure of the land slab B (not shown) using lap splices or mechanical reinforcing bar splices.

[0027] Next, on the landward side of the panel material 15, which has been vertically positioned at a desired height (Z direction) and distance (X direction) on the seaward side of the sheet pile wall 11, concrete is filled into the gap between the panel material 15 and the land slab B (including the gap between the panel material 15 and the sheet pile wall 11), the upper part of the sheet pile wall 11 and the area around its top, and the space that will become the land slab (concrete pouring process). When filling concrete on the seaward side of the sheet pile wall 11 in this manner, the formwork 31 attached to the bottom surface of the panel material 15 is slid horizontally (X direction) to completely seal the gap between the inner surface of the panel material 15 and the outer surface of the sheet pile wall 11.

[0028] In this way, the heads of the sheet piles 10 and the connecting reinforcing bars 30 are embedded in concrete, and as the concrete hardens, a coping section 40 is formed. The coping section 40 is positioned on the landward side of the panel material 15 with the heads of the sheet piles 10 and the connecting reinforcing bars 30 embedded, thereby integrally constructing the half-precast quay wall structure 1 over the entire quay wall 2 covered by the land slab B.

[0029] In this half-precast quay wall structure 1, in the connecting structure 4 in which panel materials 15 are connected to the sheet pile wall 11, the position of the panel materials 15 can be easily adjusted by operating the turnbuckles 23 and 24, which are length adjustment means provided on the first truss member 21 and the second truss member 22, and the panel materials 15 can be positioned vertically at a desired height (Z direction) and distance (X direction).

[0030] Furthermore, in this embodiment, the half-precast quay wall structure 1 can integrate the revetment section A, in which the sheet pile wall 11 is embedded, with the land slab B by connecting reinforcing bars 30 that protrude from the precast concrete panel material 15 toward the land and extend into the interior of the land slab B. With this half-precast quay wall structure 1, a structure that can withstand heavy cargo handling operations can be easily constructed. The panel material 15 can be made self-supporting relative to the sheet pile wall 11 by a truss structure consisting of a first truss member 21 and a second truss member 22, and by using this as a half-precast structure that also serves as formwork material, the labor required for setting up formwork on the sea side (setting up the panel material 15) can be reduced. As a result, it is possible to efficiently ensure the unity between the land slab B and the sheet pile wall 11 while suppressing overhang toward the sea.

[0031] Furthermore, by directly suspending the panel material 15 with the second truss member 22 and suppressing overturning with the first truss member 21 against the vertical and horizontal hydraulic pressure during concrete placement, the bending moment loaded onto the panel material 15 can be reduced, minimizing the impact on shear bending load capacity. This makes it possible to simplify the design for both temporary and permanent use in the section integrated with the land slab B. By supporting the panel material 15 from the sheet pile wall 11 with the first truss member 21 and the second truss member 22, a mechanism can be formed that resists horizontal forces, vertical forces, and overturning moments generated during concrete placement. Due to the nature of the truss structure, the fastening members do not bear bending moments, so turnbuckles or anchor bolts are sufficient as rod members, eliminating the need for special heavy machinery for installation. Furthermore, regarding the ease of installation of the panel material 15, in the conventional top-hooking method, the height difference at the top of the sheet pile wall 11 must be welded and fixed in accordance with the installation accuracy of the cap concrete, requiring precise construction management in the stage prior to the installation of the panel material 15. According to the present invention, since the vertical direction can be extended and adjusted with the turnbuckles 23 and 24, the welding and fixing of the gusset plate (connecting hardware 20) does not require strict control of the height difference.

[0032] Furthermore, if hoop reinforcement bars 16 and wire mesh reinforcement bars 17 are attached to multiple locations on the landward surface of the panel material 15, the hoop reinforcement bars 16 and wire mesh reinforcement bars 17 will be embedded in the concrete when concrete is filled into the landward side of the panel material 15. As a result, the hoop reinforcement bars 16 and wire mesh reinforcement bars 17 will be firmly held together with the coping section 40, and a shear barrier will be formed between the panel material 15 and the coping section 40. This will ensure that the panel material 15, which is the concrete cover on the seaward side, can reliably withstand the shear force generated.

[0033] In conventional technology, the bottom surface of the panel material 15 is shaped to match the shape of the steel pipe sheet piles, hat-shaped steel sheet piles, etc. used for the sheet piles 10, but this presents difficulties in manufacturing, such as reinforcement and formwork. Also, when it is desired to align the panel material with the quay wall slope, the distance between the bottom surface of the panel material 15 and the sheet pile wall 11 may vary significantly depending on the ground deformation of the quay wall. In this embodiment, these two problems are addressed by making the bottom surface of the panel material 15 straight, thereby reducing manufacturing effort. Instead, a formwork 31 fitted to the shape of the sheet pile 10 is used to reduce the gap between the sheet pile 10 and the panel material 15, preventing concrete leakage. The formwork 31 is supported by support hardware 33 and sliding hardware 32. The support hardware 33 is suspended from the bottom surface of the panel material 15 by bolts 34, and the formwork 31 and sliding hardware 32 are supported by being sandwiched in the gap between the bottom surface of the panel material 15 and the support hardware 33. The sliding metal fitting 32 is shaped like a flat steel with an elongated hole 35, and a bolt 34 that penetrates vertically serves as a guide, allowing the sliding metal fitting 32 to slide in the X direction along the elongated hole 35. Therefore, the distance to the sheet pile 10 can be widely adjusted, and by sliding and positioning its tip so that it reaches near the outer surface of the sheet pile 10, and by arranging multiple fittings in a direction parallel to the sheet pile wall 11, the formwork 31 can be effectively supported from below. As a result, the vertical concrete hydraulic pressure acting on the formwork 31 is transmitted to the sliding metal fitting 32, then to the support fitting 33, and finally to the panel material 15 via the bolt 34. In other words, the sliding metal fitting 32 can provide the formwork 31 with high resistance to bending moment and shear force. To obtain such effects, it is advisable to reinforce the formwork 31 with a high-rigidity member. However, the sheet pile wall 11 is subject to the problem of pile driving accuracy, and the shape and dimensions of the formwork tip must be adjusted on-site according to the positional displacement of the piles at the site, and the reinforcing members fixed to the formwork 31 become an obstacle. As in this embodiment, if the reinforcing members are made as sliding metal fittings 32 and separated and independent from the formwork 31, this obstacle can be avoided. Note that the positional relationship of the support fittings 33 with the panel material 15 does not change, and structural steel with high cross-sectional performance may be used.

[0034] Next, we will describe an embodiment of the connecting structure 4, in which a first connecting fitting is attached to the upper end of the sheet pile 10, a second connecting fitting is attached to the land side of the panel material 15, and the second connecting fitting is placed on top of the first connecting fitting. Note that components having substantially the same functional configuration as those described earlier in Figures 1-4 are denoted by the same reference numerals, thus omitting redundant explanations.

[0035] As shown in Figures 5 and 6, in this embodiment, the half-precast quay wall structure 1, in which the panel material 15 is connected to the sheet pile wall 11 by the connecting structure 4, has a first connecting fitting 51 attached to the upper end of the sheet pile wall 11 (sheet pile 10), and a second connecting fitting 52 attached to the landward surface of the panel material 15. The first connecting fitting 51 is provided with a receiving portion 53 for placing the second connecting fitting 52 on, and by placing a part of the bottom surface portion 54 of the second connecting fitting 52 on this receiving portion 53, the relative position and orientation of the panel material 15 with respect to the sheet pile wall 11 are roughly adjusted. Furthermore, with a portion of the bottom surface 54 of the second connecting fitting 52 resting on the receiving portion 53 of the first connecting fitting 51, the lengths of the first truss member 21 and the second truss member 22 can be adjusted, making it possible to move the panel material 15 to a desired height (Z direction) and distance (X direction) on the seaward side of the sheet pile wall 11. In addition, the panel material 15 can be rotated around the Y axis, centered on the position where the receiving portion 53 and the bottom surface 54 are in contact.

[0036] In this embodiment of the connecting structure 4, the first truss member 21 is installed to connect the first connecting hardware 51 and the second connecting hardware 52. The second truss member 22 is installed to connect the first connecting hardware 51 and the land-side surface (bracket 28) of the panel material 15. The first truss member 21 and the second truss member 22 are equipped with turnbuckles 23 and 24 as length adjustment means.

[0037] As shown in Figure 6, in this embodiment, the installation height of the panel material 15 supported by the sheet pile 10 can be finely adjusted by inserting a shim 60 between the receiving portion 53 of the first connecting fitting 51 and the bottom surface portion 54 of the second connecting fitting 52. In addition, the distance (in the X direction) between the sheet pile 10 and the panel material 15 can be finely adjusted by rotating a bolt 61 interposed between the first connecting fitting 51 and the second connecting fitting 52.

[0038] In the connecting structure 4 according to this embodiment, in the panel material placement process in which the panel material 15 is placed on the seaward side of the sheet pile wall 11, the weight of the panel material 15 can be supported by the sheet pile 10 via the first connecting hardware 51 by placing a part of the bottom surface 54 of the second connecting hardware 52 on the receiving portion 53 of the first connecting hardware 51. With the weight of the panel material 15 supported by the sheet pile 10 in this way, the panel material 15 can be vertically positioned at a desired height (Z direction) and distance (X direction) on the seaward side of the sheet pile wall 11 by operating the turnbuckles 23 and 24 provided on the first truss member 21 and the second truss member 22, respectively, making it possible to easily adjust the position and orientation of the panel material 15. In addition, by inserting a shim 60 between the receiving portion 53 of the first connecting fitting 51 and the bottom portion 54 of the second connecting fitting 52, it is possible to finely adjust the installation height of the panel material 15 supported by the sheet pile 10. Furthermore, by rotating the bolt 61 interposed between the first connecting fitting 51 and the second connecting fitting 52, it is also possible to finely adjust the distance (in the X direction) between the sheet pile 10 and the panel material 15.

[0039] Although an example of an embodiment of the present invention has been described above, the present invention is not limited to the illustrated form. It will be clear to those skilled in the art that various modifications or variations can be conceived within the scope of the idea described in the claims, and these will naturally also fall within the technical scope of the present invention.

[0040] For example, in the above embodiment, since the sheet piles 10 used for the revetment bear bending moments, steel pipe sheet piles (steel pipe piles) were used as an example in the explanation, but hat-shaped, Z-shaped, and U-shaped steel sheet piles can also be installed. In addition, although an example in which hoop reinforcement 16 and wire mesh reinforcement 17 are attached to the landward surface of the panel material 15 was explained, either the hoop reinforcement 16 or the wire mesh reinforcement 17 may be used, or they may be omitted. Furthermore, although the horizontal bolts 25 connecting the sheet piles 10 and the panel material 15 were shown as being fixed with anchor plates, this can also be done by welding or embedding nuts. In addition to the connecting reinforcing bars 30, general main reinforcement bars and distribution bars may also be installed in the coping section 40 and within the land slab B to reinforce the concrete. Furthermore, the connecting reinforcing bars 30 may be connected to the main reinforcement bars and distribution bars. Furthermore, as described above, the base end (base end portion 30a) of the connecting reinforcing bar 30 may be embedded in the panel material 15, or it may be connected to the internal reinforcing bars of the panel material 15 via a reinforcing bar connector embedded in the panel material 15.

[0041] Furthermore, the structure used in this invention, which connects a sheet pile wall with a panel material covering its exterior, can be used not only in the construction of quay wall structures but also in other applications such as retaining walls to prevent the collapse of cliffs on the side of roads.
