[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-59337 Summary of the Invention [Problem to be solved by the invention]

[0004] In this slip form construction method, the formwork rises as the yoke is raised, and the forming space rises as well. By raising the forming space while pouring concrete, it is possible to form a relatively long structure in the vertical direction.

[0005] In the conventional techniques described above, there is no working space for performing work on the molded product (such as providing a lining material or welding) after the yoke is raised, making it difficult to perform such work.

[0006] Therefore, an object of the present disclosure is to improve the workability of work related to the molded product that is performed after the yoke is raised. [Means for solving the problem]

[0007] In one aspect, there is provided an apparatus for slipform construction, comprising: a yoke for holding a mold frame that forms a molding space or a structural member that also functions as the mold frame; a climbing mechanism for raising the yoke; a scaffolding forming member that forms a bottom surface of a work space for a molded product after the yoke is raised, the scaffolding forming member being located below the formwork or the structural member and outside the formwork or the structural member in a top view; a support member extending in the vertical direction and supporting the scaffolding member relative to the yoke; An apparatus is provided in which the support member is offset outwardly relative to the formwork or structural member in a top view. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to improve the workability of work related to the molded product that is performed after the yoke is raised. [Brief explanation of the drawings]

[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 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 engages 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.

[0023] The pillar portions 33 extend downward from the supported portion 31 and support the formwork 40. The pillar portions 33 may be provided in pairs on both radial sides of the formwork 40.

[0024] 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.

[0025] In this embodiment, concrete material is poured (cast) into the molding space formed by the formwork 40. Reinforcing bars 90 in the vertical direction and reinforcing bars 92 in the horizontal direction are arranged in the molding space.

[0026] After the material poured into the molded space has hardened in the desired manner, the formwork 40 rises (rising while slipping against the cast molded object) due to the operation of the climbing mechanism 20, forming a new molded space above it. In this way, by pouring material into the molded space while raising the molded space together with the formwork 40, a skeleton 10 of the desired height can be formed. Hereinafter, the term "mold molded object" refers to the molded object formed by pouring material into the formwork 40, and in this embodiment, it refers to the concrete skeleton that has been removed from the formwork 40.

[0027] 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 via the column portions 33. 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.

[0028] The box truss 50 is fixed to the columns 33 and is supported by the climbing rods 22 via the columns 33. In this embodiment, the lower ends of the columns 33 are joined to the side surfaces of the box truss 50. The columns 33 may extend straight up and down to the lower end of the box truss 50 and be joined to the side surfaces of the box truss 50.

[0029] The lower column members 60 extend downward from the box truss 50 in a manner that extends below the formwork 40. The lower column members 60 are fixed to the box truss 50. The lower column members 60 may be integral with the box truss 50 or may be part of the box truss 50. The lower column members 60 have an L-shaped cross section and a horizontal portion 61 at the bottom. Similar to the box truss 50, the lower column members 60 may be provided in pairs on the radially inner and radially outer sides. Hereinafter, when particularly distinguishing between them, the radially inner lower column member 60 will be referred to as the radially inner lower column member 601, and the radially outer lower column member 60 will be referred to as the radially outer lower column member 602. Features of the lower column members 60 will be described later.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] The floor member 72 forms the underside of the work space related to the next mold forming space (hereinafter, for the sake of distinction, also referred to as the "pre-pouring work space"). Work related to the pre-pouring work space is work performed by humans and / or machines. The pre-pouring work space is optional, but may be a space for arranging objects or machines. For example, the pre-pouring work space may include a space for installing embedded fittings, a space for installing reinforcing bars 92, etc., as described below. The pre-pouring work space may also be a space where workers can walk.

[0034] The floor members 73 form the underside (scaffolding) of a work space (hereinafter, for the sake of distinction, also referred to as a "post-pouring work space") for the upper part of the skeleton 10 being formed. The post-pouring work space is formed in a paired manner, radially inward and radially outward relative to the upper part of the skeleton 10 being formed. The upper part of the skeleton 10 being formed corresponds to the upper part of the molded product that has been cast by pouring, which has been completed at this point.

[0035] The work related to the post-pouring work space is work performed by humans and / or machines. The post-pouring work space may be a space for arranging objects and machines. For example, as described below, the post-pouring work space may include at least one of an attachment space for attaching a lining material 110 (described below) to a molded object, an arrangement space for an unwinding device (see unwinding device 99A described below) that unwinds the lining material 110 (described below), an arrangement space for a moving means for moving the unwinding device, an arrangement space for a welding device (see welding machine 120 described below), and an arrangement space for a moving means for moving the welding device. The post-pouring work space may also be a space where workers can walk.

[0036] In the following description, the outside of the post-pouring work space refers to the side farther from the molded space when viewed from above. In other words, the outside of the post-pouring work space refers to the side radially inward from the radially inner boundary of the post-pouring work space, or the side radially outward from the radially outer boundary of the post-pouring work space. The same applies to the outside of the molded product, which refers to the side away from the molded product when viewed from above. In other words, the outside of the molded product refers to the side radially inward from the radially inner boundary of the molded product, or the side radially outward from the radially outer boundary of the molded product.

[0037] In a modified example, some of the components of the slip form construction device 1 may be omitted, or other components may be added. For example, the floor member 71 and the box truss 50 may be omitted. For example, if the box truss 50 is omitted, a connecting member extending horizontally (a member corresponding to the horizontal member at the top of the box truss 50) may be provided between the upper end of the lower column member 60 and the lower end of the column portion 33.

[0038] 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.

[0039] Next, the features of this embodiment will be described with reference to FIG.

[0040] FIG. 2 is a cross-sectional view of a main part of the slip form construction device 1 according to this embodiment.

[0041] In this embodiment, the lower column material 60 is arranged outside the post-pouring work spaces S41 and S42. Specifically, the radially inner lower column material 601 is arranged radially inside the radially inner post-pouring work space S41, and the radially outer lower column material 602 is arranged radially outside the radially outer post-pouring work space S42.

[0042] Here, the effects of this embodiment will be described in comparison with the comparative example shown in FIGS.

[0043] 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.

[0044] 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 lower column material 60 is replaced with a lower column material 60'.

[0045] The lower column material 60' is arranged inside the post-casting work spaces S41 and S42, unlike the lower column material 60 of this embodiment. In this case, the lower column material 60' extends straight in the vertical direction, integrated with the column portion 33.

[0046] In this comparative example, access to the molded article from the post-pouring work spaces S41 and S42 is locally obstructed by the lower column 60'. As a result, for example, when attaching a lining material 110 (see FIG. 4) such as a stainless steel plate to the molded article, the circumferential length of the lining material 110 is limited, for example, by reducing the circumferential length of the lining material 110 to less than the distance between adjacent lower column members 60' in the circumferential direction (i.e., the yoke span). FIG. 4 shows the lining material 1102 before attachment.

[0047] As described above, the comparative example has the problem that the number of joints of the lining material 110 in the circumferential direction increases, which increases the number of work steps and costs, and also increases the cycle time (decreases the construction speed).

[0048] Furthermore, when performing surface treatment on the molded product or chipping out embedded metal fittings, according to the comparative example, the lower column material 60' hinders continuous work in the circumferential direction, resulting in inconveniences such as reduced work efficiency. Also, when using a welding machine 120 (see FIG. 4) to join adjacent lining materials 110 in the vertical direction by welding, the lower column material 60' hinders continuous work in the circumferential direction, resulting in inconveniences such as reduced work efficiency.

[0049] In contrast to this, according to this embodiment, as described above, the lower column material 60 is arranged outside the post-pouring work spaces S41, S42, so that the inconveniences and problems that occur in the comparative example described above can be reduced or eliminated. That is, according to this embodiment, access to the molded object (part of the skeleton 10) from the post-pouring work spaces S41, S42 is not locally obstructed by the lower column material 60, so workability related to the molded object can be improved.

[0050] Furthermore, according to this embodiment, even when performing surface treatment on the molded product or chipping out of embedded metal fittings, the lower column material 60 does not hinder continuous work in the circumferential direction, so workability is good. Workability is also good when using a welding machine 120 to join adjacent lining materials 110 in the vertical direction by welding.

[0051] In this way, according to this embodiment, it is possible to improve the workability of the work relating to the molded product that is carried out after the yoke is raised.

[0052] With reference to Figure 5 and subsequent figures, some examples of preferred uses of the post-pouring working space according to this embodiment will be shown.

[0053] FIG. 5 is an explanatory view of a method for attaching a lining material 110 having a relatively long circumferential length to a molded product, and is a partially cross-sectional perspective view similar to FIG.

[0054] In the example shown in FIG. 5, the floor member 73 is openable and closable so as to open in the vertical direction. That is, the floor member 73 is openable and closable so that the lining material 110 to be lifted can pass through in the vertical direction. Specifically, the radially inner floor member 73 has a radially inner portion 731 that can rotate about a rotation axis in a horizontal plane relative to a radially outer portion 732 via a hinge 734. The radially outer portion of the radially outer floor member 73 may also be rotatable about a rotation axis in a horizontal plane relative to the radially inner portion. In FIG. 5, the portion 731 is shown in an open state. In this case, for example, the lining material 110 can be lifted from below the floor member 73 to above it, inside the lower column member 60 (the side closer to the molded product), using a hoist 96 that may be provided at the top of the post-pouring work space. In this case, lifting can be performed inside the lower column 60 (closer to the molded object), so that lining material 1104 longer than the yoke span can be easily lifted (lifted to the work space after pouring). In Figure 5, of the two lining materials 1104, the lower one shows the state before lifting, and the upper one shows the state during lifting.

[0055] FIG. 6 is an explanatory view of a welding method after the lining material 110 is attached to the molded article, and is a partially sectional perspective view similar to FIG.

[0056] In the example shown in FIG. 6, the welding machine 120 is movable in the circumferential direction to join the lining materials 110 adjacent to each other in the vertical direction by welding. For example, in the example shown in FIG. 6, the welding machine 120 is fixed to a carriage 98. The carriage 98 is movable over the entire circumferential range by means of rails 981 or the like. In this case as well, in the post-pouring work space, by moving the carriage 98 in the circumferential direction, the welding machine 120 can continuously perform the work of joining the lining materials together by welding over the entire circumferential range. Note that the carriage 98 may also be used for other purposes, such as material transportation.

[0057] FIG. 7 is an explanatory diagram of a method for attaching the lining material 110 using the unwinding device 99A, and is a partially cross-sectional perspective view similar to FIG.

[0058] In the example shown in Fig. 7, an unwinding device 99A that unwinds the sheet material 1106 that becomes the lining material 110 is arranged inside the lower column 60 (inside the post-pouring work space). In this case, in the post-pouring work space, the sheet material 1106 can be attached over the entire circumferential range while being unwound from its tip end by the unwinding device 99A. In this case, the unwinding device 99A is arranged in a fixed position.

[0059] 7, 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 in the post-pouring work space by means of rails 981A or the like. In this case as well, in the post-pouring work space, the sheet material 1106 can be attached over the entire circumferential range while unwinding the sheet material 1106 from the unwinding device 99A by moving the carriage 98A in the circumferential direction.

[0060] FIG. 8 is an explanatory view of another method for attaching the lining material 110 using the unwinding device 99A, and is a partially cross-sectional perspective view similar to FIG.

[0061] 8, 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 post-pouring work space by the circumferential rails 982A. In this case too, in the post-pouring work space, the sheet material 1106 can be installed over the entire circumferential range while unwinding the sheet material 1106 from the unwinding device 99A by moving the unwinding device 99A in the circumferential direction.

[0062] In the examples shown in FIGS. 7 and 8, adjacent lining materials 110 in the vertical direction are sequentially fixed to each other by welding, bolting, or the like. In this case, the post-pouring work space can also function as a work space for welding, bolting, or the like. FIG. 7 shows 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. 7, 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. Furthermore, in the example shown in FIG. 8, 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 shared with the unwinding device 99A.

[0063] In the above-described embodiment, the molded 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 optional, and for example, the above-described lining material 110 may be used. In this case, the skeleton 10 can be formed without using the formwork 40. That is, adjacent lining materials 110 in the vertical direction can be fixed to each other in sequence by welding, bolting, or the like, and function as a formwork for the slip-form construction method. 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 the above-described first embodiment.

[0064] 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. [Explanation of symbols]
