[0010] Each embodiment will be described in detail below with reference to the accompanying drawings. Note that the dimensional ratios in the drawings are merely examples and are not limiting. Furthermore, shapes and the like in the drawings may be partially exaggerated for the sake of explanation. Furthermore, in the drawings, for ease of viewing, reference symbols may be assigned only to some of the parts that exist with the same attribute.

[0011] Fig. 1 is a partially cross-sectional perspective view showing an example of a slip form construction apparatus 1 according to this embodiment. Fig. 1 shows half of the slip form construction apparatus 1 cut away. Fig. 1 also shows a part of a skeleton 10 formed by the slip form construction apparatus 1. Fig. 1A is a perspective view of a further part of Fig. 1 (a part related to one yoke 30).

[0012] In the following description, a top view refers to a view along the direction of gravity, and a cross-sectional view refers to a view along a direction perpendicular to the cut plane shown in FIG.

[0013] In this embodiment, as an example, the body 10 has an annular shape when viewed from above, but the shape of the body 10 is arbitrary. In the following description, the radial direction refers to the radial direction based on the annular shape of the body 10, and the circumferential direction refers to the circumferential direction based on the annular shape of the body 10. Furthermore, the radially inner side refers to the side closer to the center (center of the circle) based on the annular shape of the body 10, and the radially outer side refers to the opposite side.

[0014] The slip form construction apparatus 1 is suitable for use in the slip form construction method. The slip form construction method is widely known in the art and will not be described in detail. The details of the slip form construction method to which the slip form construction apparatus 1 can be applied are arbitrary.

[0015] The slipform construction device 1 includes a climbing mechanism 20, a yoke 30, a formwork 40, a box truss 50, a retaining member 56, a lower column member 60, and floor members 71, 72, and 73.

[0016] A plurality of climbing mechanisms 20 may be provided in pairs with the yoke 30 to form one body 10 as shown in FIG.

[0017] The climbing mechanism 20 is a mechanism for raising the yoke 30 and includes a climbing rod 22 and a lifting jack 24 .

[0018] The climbing rod 22 extends in the vertical direction. The upper end of the climbing rod 22 is a free end. As construction using the slip form method progresses, the climbing rod 22 is extended as needed and integrated with the main body 10 from below. The climbing rod 22 is installed in a manner that penetrates the yoke 30 in the vertical direction. The cross-sectional shape of the climbing rod 22 is optional.

[0019] The lifting jack 24 is attached to the climbing rod 22. The lifting jack 24 generates a force that lifts the yoke 30, and transmits the downward force received from the yoke 30 to the climbing rod 22. In this embodiment, the climbing rod 22 supports the yoke 30 and the like via the lifting jack 24, and is subjected to a compressive load according to the weight of the yoke 30 and the like.

[0020] The yoke 30 cooperates with the climbing mechanism 20 to raise the formwork 40 .

[0021] The yoke 30 includes a supported portion 31 and a pillar portion 33 .

[0022] The supported portion 31 is engaged with the climbing mechanism 20. The supported portion 31 is a structure extending horizontally (in the radial direction in this embodiment), through which the climbing rod 22 is inserted and to which the lifting jack 24 is attached. In order to ensure the necessary strength and rigidity, the supported portion 31 may have a lattice structure in cross section. In other words, it may have reinforcing members such as vertical, horizontal, and diagonal braces or trusses (see Figures 15 to 18 below).

[0023] The column portion 33 extends downward from the supported portion 31 and supports the formwork 40. In this embodiment, the column portion 33 supports the formwork 40 via the box truss 50 and the retaining member 56.

[0024] In this embodiment, the pillar portions 33 are provided in pairs on both radial sides of the supported portion 31. They extend downward from the radially inner end and the radially outer end of the supported portion 31, respectively. Hereinafter, when particularly distinguishing between them, the radially inner pillar portion 33 will be referred to as the radially inner pillar portion 331, and the radially outer pillar portion 33 will be referred to as the radially outer pillar portion 332. Details of the pillar portions 33 will be described later.

[0025] The formwork 40 forms a molding space. In this embodiment, the formwork 40 includes a radially inner formwork member 41 and a radially outer formwork member 42. The formwork members 41 and 42 have a circular cylindrical shape when viewed from above. The formwork 40 forms a molding space between the formwork members 41 and 42 in the radial direction. The bottom surface of the molding space is formed by the top surface of the skeleton 10 in the process of being formed.

[0026] In this embodiment, concrete material is poured (cast) into the molding space formed by the formwork 40. Vertical reinforcing bars 90 and horizontal reinforcing bars 92 are arranged in the molding space. The method of arranging the reinforcing bars 92 will be described later.

[0027] After the material poured into the molding space has hardened in the desired manner, the formwork 40 rises (slips against the cast material after placement) due to the operation of the climbing mechanism 20, forming a new molding space above it. In this way, material is poured into the molding space while the molding space is raised together with the formwork 40, thereby forming a body 10 of the desired height. Hereinafter, the "next molding space" refers to the molding space that will be formed by the formwork 40 when it rises from its current position. The next molding space is open radially inward and outward, and is closed when the formwork 40 rises.

[0028] The box truss 50 has a box shape in a cross-sectional view. The box truss 50 may be continuously arranged in the circumferential direction so as to form a ring shape in a top view. The box truss 50 faces the formwork 40 in the radial direction. Specifically, the box truss 50 includes a radially inner box truss 51 that faces the formwork member 41 from the radially inner side, and a radially outer box truss 52 that faces the formwork member 42 from the radially outer side.

[0029] The box truss 50 is fixed to the column portions 33. In this embodiment, the lower ends of the column portions 33 are joined to the side surfaces of the box truss 50. The column portions 33 may extend straight up and down to the lower end of the box truss 50 and be joined to the entire side surfaces of the box truss 50 from the upper end to the lower end. Specifically, the radially inner column portion 331 is joined to the radially inner side surface of the radially inner box truss 51, and the radially outer column portion 332 is joined to the radially outer side surface of the radially outer box truss 51. In this case, the column portions 33 face the formwork 40 in the radial direction via the box truss 50.

[0030] The retaining member 56 is disposed radially between the formwork 40 and the box truss 50. The retaining member 56 is in the form of a column extending in the vertical direction, and is connected to the formwork 40 and the box truss 50. The retaining member 56 may be integrated into the formwork 40 and / or the box truss 50. The retaining member 56 includes a radially inner retaining member 561 that abuts against the formwork member 41 from the radially inner side, and a radially outer retaining member 562 that abuts against the formwork member 42 from the radially outer side.

[0031] The lower column members 60 extend downward from the lower ends of the retaining members 56 in a manner that extends downward below the formwork 40. The lower column members 60 are fixed to the retaining members 56, but may also be fixed to the box truss 50. The lower column members 60 may also be members that are integrated with the retaining members 56. The lower column members 60 have an L-shaped cross section and have a horizontal portion 61 below. The lower column members 60 may be provided in pairs corresponding to the retaining members 561, 562.

[0032] The floor members 71, 72, and 73 have a plate-like shape that provides a horizontal surface (floor surface). In this embodiment, the floor members 71, 72, and 73 extend in an annular shape. The floor members 71, 72, and 73 may be provided in pairs. That is, the floor members 71, 72, and 73 may be provided on the radially inner side and the radially outer side, respectively.

[0033] Floor members 71, 72, and 73 are provided at different heights. Specifically, floor member 71 is provided with the upper surfaces of the multiple yokes 30 (upper surfaces of the supported portions 31) as a seating surface. Floor member 72 is provided with the upper surface of the box truss 50, which has an annular shape in top view, as a seating surface. Floor member 73 is provided with the horizontal portions 61 of the multiple lower column members 60 as a seating surface.

[0034] The floor member 71 forms the lower surface of the work space (hereinafter, for the sake of distinction, also referred to as the "upper work space"). For example, the floor member 71 may form a foothold for workers and materials.

[0035] The floor members 72 form the underside (scaffolding) of a work space (hereinafter, also referred to as a "pre-pouring work space" for the sake of distinction) related to the next mold forming space. The pre-pouring work spaces are formed in pairs, radially inward and radially outward relative to the mold forming space.

[0036] The work related to the pre-pouring work space is work performed by humans and / or machines. The pre-pouring work space may be a space for arranging objects and machines. For example, as described below, the pre-pouring work space may include at least one of a space for installing embedded fittings, a space for installing reinforcing bars 92, a space for arranging an unwinding device 99 (described below) that unwinds reinforcing bars 92, a space for arranging a moving means for moving the unwinding device, a space for welding work, a space for arranging a welding device (see welding machine 120 described below), and a space for arranging a moving means for moving the welding device. The pre-pouring work space may also be a space where workers can walk.

[0037] In the following description, the outside of the pre-pouring work space refers to the side farther from the next mold forming space when viewed from above. In other words, the outside of the pre-pouring work space refers to the side radially inward from the radially inner boundary of the pre-pouring work space, or the side radially outward from the radially outer boundary of the pre-pouring work space. The same applies to the outside of the next mold forming space, which refers to the side farther from the next mold forming space when viewed from above. In other words, the outside of the next mold forming space refers to the side radially inward from the radially inner boundary of the next mold forming space, or the side radially outward from the radially outer boundary of the next mold forming space.

[0038] The floor member 73 forms the underside of a work space relating to the upper part of the skeleton 10 being formed (hereinafter, for the sake of distinction, also referred to as the "post-pouring work space"). The upper part of the skeleton 10 being formed corresponds to the upper part of the molded product for which pouring has been completed at this point. Work relating to the post-pouring work space is optional.

[0039] In a modified example, some of the components of the slip form construction apparatus 1 may be omitted, or other components may be added. For example, the lower column members 60, the floor members 71, and / or 73 may be omitted.

[0040] The yoke 30 may also be supported on the earth (for example, underground or on an underground outer wall) or a fixed object in a manner that it is suspended from above by a climbing rod. In this case, the lifting jack 24 of the climbing mechanism 20 may be positioned above the yoke 30. In this case, the yoke 30 may be coupled to the lower end (for example, the free end) of the climbing rod to engage with the climbing mechanism.

[0041] Next, the features of this embodiment will be described with reference to FIG.

[0042] Fig. 2 is a cross-sectional view of the main part of the slip form construction device 1 according to this embodiment. In Fig. 2, the next molding space is schematically shown by the region within a dashed line frame S33.

[0043] In this embodiment, the column sections 33 of the yoke 30 are arranged outside the pre-pouring work spaces S31 and S32. Specifically, the radially inner column section 331 is arranged radially inside the radially inner pre-pouring work space S31, and the radially outer column section 332 is arranged radially outside the radially outer pre-pouring work space S32.

[0044] Here, the effects of this embodiment will be described in comparison with the comparative example shown in FIGS.

[0045] Fig. 3 is a cross-sectional view of a main part of a slip form construction device 1' according to a comparative example. Fig. 4 is a partially cross-sectional perspective view showing a slip form construction device 1' according to a comparative example. Fig. 5 is an explanatory diagram of the effect of this embodiment.

[0046] The slip form construction apparatus 1' according to the comparative example differs from the slip form construction apparatus 1 according to the present embodiment in that the pillar portion 33 is replaced with a pillar portion 33'.

[0047] Unlike the column portion 33 of this embodiment, the column portion 33' is arranged inside the pre-pouring work spaces S31 and S32 (closer to the next mold forming space S33). In this case, the column portion 33' extends straight in the vertical direction while being integrated with the holding member 56.

[0048] In this comparative example, access from the pre-pouring work spaces S31 and S32 to the next forming space S33 is locally obstructed by the column 33'. As a result, for example, when placing horizontal reinforcing bars 92 in the next forming space S33, the circumferential length of the reinforcing bars 92 is limited, for example, by reducing the circumferential length of the reinforcing bars 92 to less than the distance between adjacent column sections 33' in the circumferential direction (i.e., the yoke span). Figure 4 shows a short reinforcing bar 920 and a long reinforcing bar 922 before installation for reference. The reinforcing bar 922 is longer than the circumferential length between the column sections 33', and therefore the workability of placing the reinforcing bar 922 in the forming space is poor.

[0049] As described above, the comparative example has problems such as an increase in the number of joints, which increases the number of work steps and costs, an increase in cycle time (a decrease in construction speed), and over-dense reinforcement at joints (not shown).

[0050] Furthermore, even when installing embedded fittings (not shown) instead of reinforcing bars 92, according to the comparative example, depending on the size and number of the embedded fittings, they may interfere with the column portion 33', resulting in inconveniences such as reduced workability.

[0051] In contrast, according to this embodiment, as described above, the column portions 33 of the yoke 30 are positioned outside the pre-pouring work spaces S31 and S32, thereby reducing or eliminating the inconveniences and problems that occur in the comparative example. That is, according to this embodiment, access from the pre-pouring work spaces S31 and S32 to the next mold forming space S33 is not locally obstructed by the column portions 33, thereby improving workability in the next mold forming space S33. In comparison with FIG. 4 , FIG. 5 shows a short reinforcing bar 920 and a long reinforcing bar 922 before installation for reference. Although the reinforcing bar 922 is longer than the circumferential distance between the column portions 33, this embodiment facilitates workability in placing the reinforcing bar in the mold forming space. When the reinforcing bar 922 is introduced into the pre-pouring work space using a crane (not shown), the reinforcing bar 922 can be inserted obliquely.

[0052] Furthermore, according to this embodiment, the embedded metal fittings do not interfere with the pillar portions 33 of the yoke 30 during installation, which improves workability.

[0053] Next, with reference to FIG. 6 and subsequent figures, some examples of preferred modes of use of the pre-pouring work space according to this embodiment will be shown.

[0054] 6 to 8 are explanatory diagrams of a construction method (strand hoop construction method) using coiled reinforcing bars 92, and are partially sectional perspective views similar to FIG.

[0055] In the example shown in Fig. 6, an unwinding device 99 that unwinds coiled reinforcing bars 92 is arranged inside the column section 33 (closer to the pre-concrete pouring work space). In this case, in the pre-concrete pouring work space, construction can be carried out over the entire circumferential range while unwinding the reinforcing bars 92 from the unwinding device 99. In this case, the unwinding device 99 may be arranged in a fixed manner.

[0056] In the example shown in Fig. 7, the unwinding device 99 is arranged so as to be movable by a carriage 98. In this case, the unwinding device 99 is fixed to the carriage 98, and the carriage 98 is movable over the entire circumferential range in the pre-pouring work space by rails 981 or the like. In this case too, in the pre-pouring work space, construction can be carried out over the entire circumferential range while unwinding the reinforcing bars 92 from the unwinding device 99 by moving the carriage 98 in the circumferential direction. Note that the carriage 98 may also be used for other purposes, such as material transportation.

[0057] 8, the unwinding device 99 is suspended from above and arranged to be movable along circumferential rails 982. In this case, the unwinding device 99 can move over the entire circumferential range in the pre-concrete pouring work space by the circumferential rails 982. In this case as well, in the pre-concrete pouring work space, construction can be carried out over the entire circumferential range while unwinding the reinforcing bars 92 from the unwinding device 99 by moving the unwinding device 99 in the circumferential direction.

[0058] In the above-described embodiment, the mold forming space is formed using the formwork 40, but a structural member that also functions as a formwork may be used instead of the formwork 40. Such a structural member is arbitrary, but a lining material such as a stainless steel plate (the lining material 110 described below) is preferable. Below, an embodiment in which the lining material 110 is used instead of the formwork 40 will be described. For the sake of distinction, the above-described embodiment in which the formwork 40 is used will also be referred to as "Example 1," and the embodiment in which the lining material 110 is used will also be referred to as "Example 2."

[0059] In addition, even in the above-described first embodiment, there are cases where the lining material is attached to the skeleton 10 after pouring.

[0060] Fig. 9 is an explanatory diagram of a slip form construction device 1A according to a second embodiment, and is a perspective view showing only a portion relating to one yoke 30. Fig. 10 is an enlarged view of the main part of Fig. 9. In the following, components that may be similar to those in the first embodiment described above may be given the same reference numerals and descriptions thereof may be omitted.

[0061] The slip form construction apparatus 1A according to the second embodiment differs from the slip form construction apparatus 1 according to the above-described embodiment in that the formwork 40 is replaced by a lining material 110 and the retaining member 56 is replaced by a sliding member 56A.

[0062] The lining material 110 is provided in a manner that covers the peripheral surface of the skeleton 10. Unlike the formwork 40, the lining material 110 is integrated with the skeleton 10 and is not removed after construction.

[0063] The sliding member 56A, like the retaining member 56 according to the first embodiment described above, abuts against the lining material 110 in the radial direction and receives the radial force during pouring (transmitting it to the yoke 30, etc.). The sliding member 56A, like the retaining member 56 according to the first embodiment described above, is connected to the box truss 50.

[0064] Unlike the holding member 56, which is fixed to the formwork 40, the sliding member 56A is not fixed to the lining material 110. That is, the sliding member 56A can slide vertically relative to the lining material 110. While any sliding mode is possible, the example shown in FIG. 9 illustrates sliding. That is, the sliding member 56A forms a sliding bearing. The sliding member 56A preferably has a tapered upper portion 561A. Specifically, the sliding member 56A has a tapered shape that widens upward in cross section. In this case, when the yoke 30 rises, the possibility of vertical interference with the lining material 110 that is being arranged for the next pouring can be reduced. That is, as the sliding member 56A rises, the lower end of the lining material 110 can be guided toward the inside of the sliding member 56A.

[0065] FIG. 11 is a modified example of the example shown in FIG. 9, and is an enlarged view of the main part similar to FIG.

[0066] 11, the sliding member 56B of the slip form construction device 1B has the same function as the sliding member 56A, but has a different support mode. Specifically, the sliding member 56B incorporates a roller that contacts the surface of the lining material 110. In other words, the sliding member 56B forms a roller bearing.

[0067] According to Example 2, the skeleton 10 can be formed without using the formwork 40. That is, according to Example 2, the lining materials 110 adjacent to each other in the vertical direction can function as a formwork for the slip-form construction method while being sequentially fixed together by welding, bolting, etc. As a result, when forming the skeleton 10 equipped with the lining material 110, the formwork 40 is not required, and more efficient construction is possible compared to Example 1 described above.

[0068] Furthermore, the same effects as those of the above-described Example 1 are achieved by Example 2. That is, since the column portion 33 is the same as that of Example 1, the workability of the next molding space can be improved. That is, the reinforcing bars 92 and embedded metal fittings do not interfere with the column portion 33 of the yoke 30 during installation, and therefore the workability is good.

[0069] Moreover, according to the second embodiment, it is possible to improve the workability in applying the lining material 110. For example, the lining material 110 is in the form of a coil of thin plate and can be applied in the same manner as the horizontal reinforcement.

[0070] 12 to 14 are explanatory diagrams of a method for applying a lining material 110 in a slip form construction apparatus 1A according to Example 2, and are partially sectional perspective views similar to those of Fig. 1. This application method can also be implemented in the slip form construction apparatus 1B shown in Fig. 11.

[0071] In the example shown in Fig. 12, an unwinding device 99A that unwinds a thin coil-shaped lining material 110 is disposed inside the column portion 33. In this case, in the pre-pouring work space, construction can be carried out over the entire circumferential range while unwinding the lining material 110 from the unwinding device 99A. In this case, the unwinding device 99A is disposed in a fixed position.

[0072] 13, the unwinding device 99A is arranged so as to be movable by a carriage 98A. In this case, the unwinding device 99A is fixed to the carriage 98A, and the carriage 98A is movable over the entire circumferential range by rails 981A or the like in the pre-pouring work space. In this case as well, in the pre-pouring work space, construction can be performed over the entire circumferential range while unwinding the lining material 110 from the unwinding device 99A by moving the carriage 98A in the circumferential direction.

[0073] 14, the unwinding device 99A is suspended from above and arranged to be movable along circumferential rails 982A. In this case, the unwinding device 99A can move over the entire circumferential range in the pre-pouring work space by the circumferential rails 982A. In this case too, in the pre-pouring work space, construction can be performed over the entire circumferential range while unwinding the lining material 110 from the unwinding device 99A by moving the unwinding device 99A in the circumferential direction.

[0074] In the second embodiment, adjacent lining materials 110 in the vertical direction are sequentially fixed to each other by welding, bolting, or the like as the yoke 30 rises after pouring. In this case, the pre-pouring work space can also function as a work space for welding, bolting, or the like. FIGS. 13 and 14 show a welding machine 120. The welding machine 120 may be movable in the circumferential direction, similar to the unwinding device 99A. For example, in the example shown in FIG. 13, the welding machine 120 is fixed to a carriage 98A, similar to the unwinding device 99A. In this case, the carriage 98A may be movable on a common rail. In the example shown in FIG. 14, the welding machine 120 may be suspended via an upper circumferential rail 982A, similar to the unwinding device 99A. In this case, the welding machine 120 may also be movable via the common circumferential rail 982A.

[0075] Next, other modified examples applicable to the above-described Examples 1 and 2 will be described. Below, modified examples based on the above-described Example 1 will be described, but they can also be applied to the above-described Example 2. Furthermore, below, components that may be similar to those in the above-described Example 1 may be given the same reference numerals and descriptions thereof may be omitted.

[0076] 15 and 16 are explanatory views of a slip form construction device 1C according to a first modified example, where FIG. 15 is a perspective view similar to FIG. 1A, and FIG. 16 is a cross-sectional view similar to FIG.

[0077] In the above-described first embodiment, the column portion 33 is moved outward compared to the comparative example shown in FIGS. 3 and 4, and therefore the bending moment acting on the supported portion 31 increases.

[0078] For this reason, in the slip form construction device 1C according to the first modified example, a brace 314C is provided on the supported portion 31C of the yoke 30C, as shown in FIGS. 15 and 16. This ensures the necessary rigidity of the supported portion 31C even when a relatively large bending moment acts on the supported portion 31C. Note that FIG. 16 shows forces F161 and F162 that cause the bending moment. Force F161 is the sum of force F162, the weight of the yoke 30C, etc., and the weight of the load. Force F162 is a force due to frictional resistance that occurs when the yoke 30C rises. Note that forces F161 and F162 are generated in the same manner in the above-described first embodiment, etc.

[0079] In addition, in the first modified example, an additional brace 315C is provided to ensure the necessary rigidity to bear the load from the lifting jack 24. In this way, various braces may be provided according to the required rigidity.

[0080] 17 and 18 are explanatory views of a slip form construction device 1D according to a second modified example, where FIG. 17 is a perspective view similar to FIG. 1A, and FIG. 18 is a cross-sectional view similar to FIG.

[0081] As in the first modified example, the slip form construction device 1D according to the second modified example is provided with braces 314D and 315D as shown in Figures 17 and 18. In the second modified example, the supported part 31D of the yoke 30D is made up of two upper and lower horizontal members 317D and 318D, of which the upper horizontal member 318D is shorter in length, and therefore the lower horizontal member 317D and the upper horizontal member 318D are connected by an upper and lower member 319D which is located inside the column part 33 (the side closer to the formwork 40).

[0082] Fig. 19 is an explanatory diagram of a slip form construction device 1E according to a third modified example. In the third modified example, the supported portion 31E is formed by a single horizontal member. In the example shown in Fig. 19, the lower column member 60 and floor members 71, 73, etc. are omitted.

[0083] Although each embodiment has been described in detail above, it is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the claims. It is also possible to combine all or a plurality of components of the above-described embodiments.

[0084] For example, in the above-described embodiment, the radially inner column 331 is arranged radially inside the radially inner pre-pouring work space, and the radially outer column 332 is arranged radially outside the radially inner pre-pouring work space, but this is not limited to this. That is, only one of the radially inner column 331, 332 may be arranged in this manner. For example, the radially inner column 331 is arranged radially inside the radially inner pre-pouring work space, but the radially outer column 332 may be arranged radially inside the radially outer pre-pouring work space, as in the above-described comparative example.

[0085] In addition, in the above-described embodiment, the box truss 50, lower column member 60, and floor members 71, 72, and 73 are arranged in pairs on the radially inner and outer sides, respectively, but they may also be arranged on only one of the radially inner and radially outer sides.
