Description

  The present invention relates to a method for forming a cured body by filling a mold with a flowable material and curing it.

  2. Description of the Related Art Conventionally, a method for forming a cured body by filling a mold with a fluid material such as concrete before curing or a heated thermoplastic resin is known. Such a cured body may be given product information such as a manufacturing date and a lot number. As a method of giving product information to the cured body, a method of printing or imprinting product information on the surface of the cured body can be considered. However, such a method requires a step of performing printing or stamping after the cured body is manufactured, and therefore the cured body cannot be shipped efficiently.

  Therefore, a method has been proposed in which a storage medium (attachment member) such as an IC chip in which product information is recorded is attached to the cured body along with the formation of the cured body. For example, a method of attaching a storage medium by burying it in a cured body has been proposed. In such a method, a storage medium is embedded in the flowable material to form a cured body in which the recording medium is embedded (see Patent Documents 1 to 3). Such a cured body can read product information from a recording medium using a device that reads the product information, and thus a process of performing printing or the like after the production of the cured body is not necessary. For this reason, it becomes possible to ship a hardening body efficiently.

However, when the recording medium is embedded in the cured body as described above, the storage medium cannot be visually recognized from the surface of the cured body. Therefore, the position of the storage medium can be specified when reading product information from the storage medium. It becomes difficult and the work of reading product information becomes complicated . Also, depending on the depth at which the storage medium is embedded, it may be difficult for a device that reads product information to read product information from the storage medium.

  Then, this invention makes it a subject to provide the formation method of the hardening body which can form the hardening body attached in the state which attachment members, such as a recording medium, can visually recognize.

  The method for forming a cured body according to the present invention uses a mold having an inner wall surface that forms a filling space filled with a flowable material, and fills the filling space with the flowable material to cure the flowable material. A method of forming a cured body with a holding step of detachably holding the attachment member on the inner wall surface so that at least a part of the attachment member attached to the cured body is exposed to the filling space. It is characterized by providing.

  According to such a configuration, in the holding step, the attachment member is held on the inner wall surface, and therefore, when the step of filling the filling space with the fluid material (hereinafter also referred to as the filling step) is performed, It is possible to prevent the attachment member from moving to an unintended position in the filling space due to the flow of the material. Further, in the holding step, since the attachment member is detachably held on the inner wall surface so that at least a part of the attachment member is exposed to the filling space, the portion exposed to the filling space in the attachment member is cured. It will be in the state by which the attachment member was attached to the hardening body by the coupling | bonding with a body. Thereby, an attachment member can be made to detach | leave from an inner wall surface with a hardening body by performing the process (henceforth a mold release process) of releasing a hardening body from a mold.

  In addition, since the mounting member is held on the inner wall surface, when the cured body is formed, a portion of the mounting member that contacts the inner wall surface is exposed on the surface of the cured body. Thereby, even after the cured body is formed, the mounting member can be easily confirmed visually. For example, when product information or the like is recorded on the mounting member, the recorded information is visually checked. Can be quickly read by a computer or a device.

  In the holding step, the attachment member is preferably held on the inner wall surface by a magnetic force.

  According to such a configuration, since the attachment member is held on the inner wall surface by the magnetic force in the holding step, it is not necessary to attach and hold the attachment member on the inner wall surface using an adhesive, an adhesive tape, or the like. For this reason, a holding process can be performed easily.

  The mold has a mold wall portion having an inner wall surface, and in the holding step, a magnetic body is disposed outside the filling space so that the mold wall portion is located between the magnetic body and the filling space. The mounting member is preferably held on the inner wall surface by the magnetic force of the magnetic body through the mold wall.

  According to such a configuration, in the holding step, the magnetic body is disposed outside the filling space so that the mold wall is positioned between the magnetic body and the filling space, and the magnetic force of the magnetic body via the mold wall is set. Since the mounting member is held on the inner wall surface, the mounting member can be easily held at any location on the inner wall surface by changing the position of the magnetic body, and the holding position can be easily changed. be able to. Moreover, since it becomes possible to hold | maintain an attachment member to an inner wall surface also in the existing formwork, the hardening body to which the attachment member was attached can be formed, without improving the existing formwork. Further, by removing the magnetic body, the mounting member can be easily detached from the inner wall surface.

  It is preferable that at least a part of the mounting member is configured to have magnetism, and in the holding step, the mounting member is held on the inner wall surface by the magnetic force of the mounting member.

  According to such a configuration, at least a part of the mounting member is configured to have magnetism, and in the holding step, the mounting member is held on the inner wall surface by the magnetic force of the mounting member. It is not necessary to attach and hold the mounting member on the inner wall surface using a tape or the like. For this reason, a holding process can be performed easily.

  The mounting member includes a main body portion held on the inner wall surface in the holding step, and a protruding portion protruding from the main body portion. In the holding step, the mounting member is arranged so that the protruding portion is located in the filling space. It is preferable to be detachably held on the wall surface.

  According to such a configuration, the attachment member includes the main body portion held on the inner wall surface in the holding step and the protruding portion protruding from the main body portion, and the protruding portion is positioned in the filling space in the holding step. Since the mounting member is detachably held on the inner wall surface, the protruding portion is embedded in the cured body. As a result, the attachment member is securely attached to the cured body by the protrusion (specifically, due to the anchor effect of the protrusion), and thus the attachment member is unintentionally separated from the cured body. Can be prevented.

  The protrusion is preferably configured to be separable from the main body.

  According to such a configuration, the protruding portion is configured to be separable from the main body portion, so that the main body portion exposed on the surface of the cured body protrudes even when the protruding portion is embedded in the cured body. Can be separated from the part. Thereby, a main-body part can be easily removed from a hardening body.

  As described above, according to the present invention, it is possible to form a cured body attached in a state where an attachment member such as a recording medium is visible.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

  In the method for forming a cured body according to the present invention, a cured material is formed by filling a mold material with a fluid material (fluid material) and curing the material. The fluid material is not particularly limited. For example, the fluid material is a mixture of a hydraulic material and water (specifically, concrete, mortar, or gypsum before curing) or heated. Examples thereof include a thermoplastic resin having fluidity.

  Moreover, in the formation method of the hardening body which concerns on this invention, the hardening body to which the attachment member was attached is formed. The mounting member is not particularly limited. For example, a member to which product information such as a manufacturing date and a lot number is given (specifically, an optical type such as a QR code (registered trademark) or a barcode). And the like). The shape of the attachment member 1 is not particularly limited, and examples thereof include a sheet-like one as shown in FIG.

  Such an attachment member 1 includes a main body 1a and a protrusion 1b that protrudes from the main body 1a (specifically, protrudes in a direction intersecting the main body 1a). Specifically, the attachment member 1 includes a protruding portion 1b that protrudes from the main body 1a toward one surface (hereinafter also referred to as an inner surface) of the sheet-like main body 1a. The attachment member 1 is formed with a main body portion 1a and a protruding portion 1b by bending a single sheet material. Specifically, the four corners of the quadrangular sheet material are bent toward one surface of the sheet material (that is, the inner surface of the main body 1a), thereby forming four triangular protrusions 1b and 4 One main body 1a is formed in the region inside the two protrusions 1b.

  Moreover, the attachment member 1 is comprised so that the main-body part 1a and the protrusion part 1b are separable. Specifically, the attachment member 1 includes a cutting auxiliary line (for example, a perforation or a half cut) between the main body 1a and the protrusion 1b, and is configured to be cut at the position of the cutting auxiliary line. Is done. Thereby, as for the attachment member 1, the main-body part 1a and the protrusion part 1b are separable.

  The length of one side of the triangular protrusion 1b is not particularly limited as long as an area where product information or the like can be displayed on the main body 1a can be secured, and is preferably 10 mm or more, for example. . In addition, the angle of the protrusion 1b with respect to the main body 1a is not particularly limited, and may be, for example, 90 °, but is preferably 45 ° or more and less than 90 °, or 90 °. It is preferably more than 135 ° or less.

  Although it does not specifically limit as a sheet | seat material which forms the attachment member 1, In this embodiment, what has a property attracted | pulled by a magnetic body is used. For example, a sheet material containing an iron component can be used. Specifically, a super heat-resistant label / tag (manufactured by SATO) or the like can be used as the sheet material. Note that product information or the like is displayed using a QR code or the like on the other surface of the sheet-like main body 1a (the surface on which the protrusion 1b does not protrude) (hereinafter also referred to as the outer surface).

  Next, the formation method of the hardening body to which the above attachment members 1 were attached is demonstrated. In this embodiment, as shown to Fig.2 (a), the mold 2 which forms the filling space R filled with a fluid material is used. The mold 2 is composed of a male mold 2a and a female mold 2b, and a filling space R is formed by combining the male mold 2a and the female mold 2b. The mold 2 (specifically, the male mold 2a and the female mold 2b) includes a mold wall portion 2d having an inner wall surface 2c that forms a filling space R.

  When forming the cured body, first, the mounting member 1 is detachably held with respect to the inner wall surface 2c so that at least a part of the mounting member 1 is exposed to the filling space R (holding step). . In the present embodiment, the mounting member 1 is detachably held with respect to the inner wall surface 2c so that the outer surface of the main body 1a of the mounting member 1 (the surface on which the protruding portion 1b does not protrude) is in contact with the inner wall surface 2c. . Thereby, the inner side surface (surface on the side from which the protruding portion 1b protrudes) and the protruding portion 1b of the main body portion 1a are exposed to the filling space R.

  A method of detachably holding the attachment member 1 on the inner wall surface 2c is not particularly limited, but in this embodiment, the attachment member 1 is held on the inner wall surface 2c by magnetic force. Specifically, a magnetic body (specifically, a magnet) 3 is disposed outside the mold 2, and the mounting member 1 is held on the inner wall surface 2 c by the magnetic force of the magnet 3 through the mold wall 2 d. . Thereby, by removing the magnet 3, the attachment member 1 can be detached from the inner wall surface 2c.

  Next, as shown in FIG. 2B, the filling space R is filled with a fluid material L (for example, concrete before curing) (filling step). Thereby, the attachment member 1 will be in the state by which parts other than the outer surface of the main-body part 1a and the protrusion part 1b were embedded in the fluid material L. FIG. Then, in such a state, the fluid material L is cured by being left for a predetermined time. Thereby, as shown to Fig.3 (a), the outer surface of the main-body part 1a of the attachment member 1 is located in the surface, and the hardening body H with which the protrusion part 1b was embedded is formed.

  When the cured body H is released from the mold 2 (release process), the magnet 3 is removed from the mold 2. Thereby, the state in which the attachment member 1 is held by the inner wall surface 2c is eliminated, and the attachment member 1 can be detached from the inner wall surface 2c. And as shown in FIG.3 (b), the hardening body H is taken out from the formwork 2 in the state to which the attachment member 1 was attached by separating the male type | mold 2a and the female type | mold 2b. Such a cured body H can read a QR code or the like displayed on the outer surface because the outer surface of the main body 1a of the mounting member 1 is located on the surface.

  As described above, according to the method for forming a cured body according to the present invention, it is possible to form a cured body that is attached in a state where an attachment member such as a recording medium is visible.

  That is, in the holding step, since the attachment member 1 is held on the inner wall surface 2c, the fluidity is also obtained when the step of filling the filling space R with the fluid material L (hereinafter also referred to as the filling step) is performed. The flow of the material L can prevent the attachment member 1 from moving to an unintended position in the filling space R. Further, in the holding step, the attachment member 1 is detachably held on the inner wall surface 2c so that at least a part of the attachment member 1 is exposed to the filling space R. The attachment member 1 is attached to the cured body H by the coupling between the exposed portion and the cured body H. Thereby, the attachment member 1 can be made to detach | leave from the inner wall surface 2c with the hardening body H by performing the process (henceforth a mold release process) of releasing the hardening body H from the mold frame 2.

  In addition, since the attachment member 1 is held on the inner wall surface 2c, when the cured body H is formed, a portion of the attachment member 1 that contacts the inner wall surface 2c is exposed on the surface of the cured body H. Thereby, even after the hardened body H is formed, the attachment member 1 can be easily confirmed visually, so, for example, when product information or the like is recorded on the attachment member 1, it is recorded. Information can be quickly read visually or with an instrument.

  Further, in the holding step, the attachment member 1 is held on the inner wall surface 2c by magnetic force, so that it is not necessary to attach and hold the attachment member 1 on the inner wall surface 2c using an adhesive or an adhesive tape. For this reason, a holding process can be performed easily.

  In the holding step, the magnetic body 3 is arranged so that the mold wall 2d is positioned between the magnetic body 3 and the filling space R, and the inner wall surface 2c is generated by the magnetic force of the magnetic body 3 via the mold wall 2d. Since the mounting member 1 is held by the mounting member 1, the mounting member 1 can be easily held at an arbitrary location on the inner wall surface 2c by changing the position of the magnetic body 3, and the holding position can be easily changed. It can be carried out. Moreover, since it becomes possible to hold the attachment member 1 on the inner wall surface 2c in the existing mold 2, the cured body H to which the attachment member 1 is attached is formed without improving the existing mold 2. Can do. Further, by removing the magnetic body 3, the mounting member 1 can be easily detached from the inner wall surface 2c.

  The mounting member 1 includes a main body 1a held on the inner wall surface 2c in the holding step, and a protruding portion 1b protruding from the main body 1a. In the holding step, the protruding portion 1b is in the filling space R. Since the attachment member 1 is detachably held on the inner wall surface 2c so as to be positioned at the position, the protruding portion 1b is embedded in the cured body H. As a result, the attachment member 1 is securely attached to the cured body H by the protrusion 1b (specifically, due to the anchor effect of the protrusion 1b). It is possible to prevent separation without being performed.

  Further, the protruding portion 1b is configured to be separable from the main body portion 1a, so that the main body portion 1a exposed on the surface of the cured body H even when the protruding portion 1b is embedded in the cured body H. Can be separated from the protrusion 1b. Thereby, the main-body part 1a can be easily removed from the hardening body H. FIG.

According to such a configuration, the magnetic force of the magnetic part 2e can be directly applied to the attachment member 1, so that the attachment member 1 can be more reliably held on the inner wall surface 2c. The method of forming the magnetic part 2e is not particularly limited. For example, the magnetic body 2e is disposed on the inner wall surface 2c side of the mold wall 2d so that a part of the magnetic body 3 is exposed to the filling space R. By embedding 3, the magnetic part 2 e can be formed.
