Description

  The present invention relates to a core hole filling apparatus and a core hole filling method for filling a core hole generated in a wall surface of a building by collecting a core.

  As one method for diagnosing the durability of a concrete structure (hereinafter referred to as a building), there is a core removal survey (core boring). In the coreless survey, a concrete core (hereinafter referred to as a core) is collected from a building wall using a boring machine. And the durability of a building is diagnosed by measuring the compressive strength etc. of the collected core.

  As described above, since the core is collected from the wall or pillar of the building, a hole (hereinafter referred to as a core hole) is formed on the wall surface of the building after the core is collected. If such a core hole is left unattended, there is a risk that rainwater, air, etc. will enter from there and contribute to the promotion of deterioration. Also, it is not preferable to leave the core hole from the viewpoint that the beauty of the building is impaired. For this reason, the core hole is usually filled after the core is removed.

  As the filler for filling the core hole, mortar and grout in which cement, sand, etc. and water are mixed are often used. As the conventional core hole filling method, the morning glory filling method, dumpling filling method and press-fitting method are mainly used. FIG. 8 is a diagram for explaining a conventional core hole filling method. 8A is a diagram for explaining the morning glory filling method, FIG. 8B is a diagram for explaining the dumpling filling method, and FIG. 8C is a diagram for explaining the press-fitting method.

  In the morning glory filling method shown in FIG. 8 (a), first, as shown in FIG. 8 (a-1), a screen 12 (sometimes called morning glory) is installed at the entrance of the core hole 10a formed in the wall 10. To do. Next, as shown in FIG. 8A-2, the filler 20 is poured into the core hole from above the partition 12. And if the filler 20 overflows on the partition 12 beyond the upper end of a core hole, filling will be complete | finished. Then, as shown in FIG. 8 (a-3), curing is performed for a predetermined time in a state where the partition 12 is installed. Thereafter, as shown in FIG. 8 (a-4), the partition 12 is removed, and the filler 20a protruding from the wall is cut.

  In the dumpling filling method shown in FIG. 8 (b), first, as shown in FIG. 8 (b-1), the dumpling-like filler 20 is pushed into the core hole 10a formed in the wall 10, and this is used as a pressing rod. 14 or the like is used to bring it into close contact with the core hole. Then, as shown in FIG. 8 (b-2), the dumpling-like filler 20 is further pushed in and pressed. If this is repeated, the state shown in FIG. Thereafter, as shown in FIG. 8 (b-4), the filler 20 protruding from the wall is removed with a trowel 16 or the like for finishing.

  In the press-fitting method shown in FIG. 8C, first, as shown in FIG. 8C-1, a jig 18 having an inlet 18a and an outlet 18b is mounted on the wall. Next, as shown in FIG. 8C-2, the filler 20 is filled into the core hole 10a through the inlet. Then, when the filling material 20 starts to be discharged from the discharge port, the filling is finished, and the curing is performed for a predetermined time with the jig installed. Then remove the jig from the wall.

  In addition to the above-described method, Patent Document 1 discloses a filling device and a filling method for filling a material into a deep hole formed in a structure. The technique described in Patent Document 1 is an improvement of the above-described dumpling filling method, and according to this, it is possible to release the internal air to the outside while filling the material from the front end side of the deep hole, and the reliability. It is said that the material can be filled into a deep hole with high and high quality.

JP 2003-307036 A

  However, in the conventional filling method shown in FIG. 8, there is a possibility that a gap is generated in the filler due to bubbles or the like. Such a gap is not preferable from the viewpoint of the structure of the building and the durability.

  Therefore, in the filling of the core hole using the conventional filling method, it is necessary to perform the work with great care so that no gap is generated in the core hole after filling, resulting in a long working time. In addition, there is a problem that the result of the work depends largely on the skill level of the worker.

  The filling device and the filling method described in Patent Document 1 can be suitably used when the filler is in a solid state (substance with low fluidity), but the filler is in a liquid state (substance with high fluidity). It was difficult to apply to.

  In view of such a problem, the present invention can fill the core hole without generating a gap without depending on the skill level of the operator even when using a filler having high fluidity, and durability of the building It is an object of the present invention to provide a core hole filling device and a core hole filling method capable of ensuring the safety and shortening the working time.

  In order to solve the above problems, a typical configuration of a core hole filling device according to the present invention is a core hole filling device that fills a core hole generated in a wall surface of a building by collecting the core, A filling tube for leading a filler for filling the core hole to the core hole, and a substantially disk-shaped member disposed at substantially the tip of the filling tube, having a diameter larger than that of the core hole and filling substantially at the center A partition member made of a porous material having an insertion hole through which a tube is inserted and having at least an outer peripheral portion being flexible, and a filler press-fitting device for press-fitting the filler into the deeper side than the partition member of the core hole through the filling tube; It is characterized by providing.

  According to the said structure, since the outer peripheral part of a partition member has a softness | flexibility, when this partition member is inserted in a core hole, the outer peripheral part will deform | transform and it will contact | adhere with the side surface of a core hole. Thereby, the space behind the partition member of the core hole is sealed with the partition member. When the filler is press-fitted into the core hole through the filler tube by the filler press-fitting device, the air in the space is expelled out of the sealed space through the pores in the outer peripheral portion made of the porous material. When the space is filled with the filler, the filler cannot pass through the porous material, and the partition member is pushed out toward the opening of the core hole as the filler is pressed. That is, the partition member is pushed out toward the opening only by press-fitting the filler with the filler press-fitting device, and the filler can be filled up to the opening without causing a gap due to air on the inner side of the core hole. Therefore, the core hole can be filled without generating a gap without depending on the skill level of the operator, and it is possible to ensure the durability of the building and shorten the work time.

  In addition, since the outer peripheral portion is made of a flexible porous material, the core hole filling device can smoothly move in the core hole. In detail, the side surface of the core hole is not necessarily flat, but is often uneven by being scraped by core boring. For this reason, if the outer peripheral portion of the partition member is made of a material having no flexibility, the outer peripheral portion is caught by the convex portion on the side surface of the core hole, and the core hole filling device can move to the inlet side of the core hole. And the core hole will not be completely filled. Therefore, by making the outer peripheral portion a flexible porous material as in the above configuration, even if the core hole has a shape with irregularities on the side surface, the outer peripheral portion can be deformed following the shape. it can. Accordingly, the core hole filling device moves while being pushed out by the filler and reaches the vicinity of the inlet of the core hole, so that the inside of the core hole can be completely filled.

  The partition member has a disk-shaped porous portion made of a porous material including an outer peripheral portion, a diameter smaller than that of the porous portion, and an insertion hole through which a filling tube is inserted substantially at the center. The first pressing plate includes a disk-shaped first pressing plate, and the first pressing plate is preferably in contact with the surface of the porous portion on the back side of the core hole to fix the porous portion.

  Since the porous material has flexibility, if the partition member is composed only of the porous material, the partition member may be deformed by being under pressure of the filler that is press-fitted from the filler press-fitting device. If a gap is generated between the partition wall member and the side surface of the core hole due to the deformation, the filler leaks out from the gap and hinders the filling of the core hole.

  Therefore, as in the above configuration, in particular, when the partition member includes the outer peripheral portion and is entirely made of a porous material, that is, when the partition member has a porous portion, the surface of the porous portion on the back side of the core hole is arranged. 1 A holding plate is provided. Thereby, since the porous material is left only in the outer peripheral portion and the porous portion is supported by the first pressing plate, the deformation of the porous portion (partition wall member) can be prevented, and the core hole is preferably filled. Is possible. Further, by making the diameter of the first pressing plate smaller than that of the porous portion, the side surface of the core hole comes into contact with the porous material of the porous portion instead of the first pressing plate. For this reason, smooth movement within the core hole of the filling device is not hindered.

  The partition member may further include a second pressing plate having substantially the same shape as the first pressing plate at the tip of the filling tube, and the porous member may be fixed to the filling tube by sandwiching the porous portion between the first and second pressing plates. . This makes it possible to more reliably fix the partition member (porous portion) to the filling tube. Furthermore, moderate tension and rigidity can be given to the partition member (porous portion), and it becomes possible to more reliably prevent the gap between the core hole and the filler from leaking out.

  Said filling pipe | tube is good in it being a pipe which consists of hard materials. According to such a configuration, the filling pipe is less likely to be deformed, so that the filling pipe can be easily kept level. Thereby, since the attitude | position of the partition member fixed to the filling pipe | tube and the press plate (1st press plate and 2nd press plate) is also maintained, the inclination of these members does not arise. Therefore, the sealed state in the core hole by the partition member can be suitably maintained, and the core hole can be reliably filled.

  The core hole filling device may further include a cap that seals the end of the filling tube opposite to the side that is introduced into the core hole.

  With this configuration, when curing the filler filled in the core hole, the end of the filling tube opposite to the side introduced into the core hole, that is, the end on the side where the filler press-fitting device is connected is provided. It is possible to prevent the filler from flowing out. Therefore, it is possible to improve the reliability of core hole filling.

  Said filling pipe | tube has a screw part in the edge part on the opposite side to the side introduce | transduced into a core hole, and it is good for a cap to have a screw hole part screwed together with a screw part on an inner surface. With this configuration, the screw portion of the filling tube and the screw hole portion of the cap are screwed together, and the end portion of the filling tube can be easily and reliably sealed with the cap.

  The core hole filling device may further include a holding jig for holding the posture of the filling tube. Thereby, it becomes possible to hold | maintain the horizontal attitude | position of a filling pipe more reliably.

  The holding jig includes a first holding part that holds the filling pipe so that the filling pipe can be inserted, a second holding part that holds the filling pipe so that the filling pipe can be inserted at a position different from the first holding part, and the holding jig on the wall surface. It is good to have the fixing | fixed part fixed.

  Since the filling tube is supported at two points by having the first holding portion and the second holding portion arranged at a position different from the first holding portion as in the above configuration, the horizontal posture of the filling tube is more reliably ensured. Can be held in. Further, by providing a fixing portion for fixing the holding jig to the wall surface, the filling tube can be fixed to the wall surface via the holding jig. Therefore, the stability of the posture of the filling tube can be improved. Further, since the holding jig and the filling tube can be fixed to the wall surface by the fixing portion, it is not necessary to hold them by the operator. For this reason, the labor of work can be reduced and the number of workers can be reduced.

  The holding jig is preferably provided with a fixing portion, further including a frame body that fixes the first holding portion so that the position thereof can be adjusted, and the second holding portion is preferably fixed to the first holding portion.

  According to the above configuration, after the frame (holding jig) is fixed to the wall surface by the fixing portion, the position of the first holding portion accommodated in the frame can be adjusted. And since the 2nd holding | maintenance part is being fixed to the 1st holding | maintenance part, even if it adjusts the position of a 1st holding | maintenance part, the relative position of a 1st holding | maintenance part and a 2nd holding | maintenance part does not change. For this reason, the position shift between these members does not occur.

  The holding jig further includes a connecting member that connects the first holding portion and the second holding portion, and the first holding portion has a substantially disc-shaped member having an insertion hole through which the filling tube is inserted at a substantially center. And the 2nd holding part is a metal fitting provided with the penetration hole which penetrates a filling pipe, Comprising: A connection member carries out 2nd maintenance in the direction which shifts the mutual penetration hole of the 1st holding part and the 2nd holding part. The position of the part should be adjustable.

  According to such a configuration, the filling tube can be easily held by the holding jig by inserting the filling tube through the insertion hole of the first holding unit and the insertion hole of the second holding unit. Moreover, the state of the wall surface which fixes a holding jig, or the core provided in this by being able to adjust the position of a 2nd holding part in the direction which shifts the mutual insertion hole of a 1st holding part and a 2nd holding part with a connection member. Fine adjustment according to the position of the hole is possible.

  The connecting member may be molded integrally with the second holding member. Thereby, it is possible to reduce the number of parts of the core hole filling device and to reduce the cost.

  Said fixing | fixed part is good in it being a long hole for fixing to the anchor bolt installed in the wall surface formed in a frame.

  The boring machine used at the time of core collection is fixed to the wall surface by anchor bolts. Therefore, according to this configuration, the anchor bolt can be used for fixing the holding jig, and the number of parts can be reduced. Moreover, when using an anchor bolt for fixing the boring machine at the time of core collection, a hole for driving the anchor bolt into the wall surface is dug. Therefore, even when the core hole is filled, the hole can be used by using the anchor bolt. As a result, it is not necessary to separately provide a hole for fixing the holding jig when filling the core hole, so that the number of work steps can be reduced.

  In order to solve the above problems, a representative configuration of a core hole filling method according to the present invention is a core hole filling method for filling a core hole generated in a wall surface of a building by collecting a core, and at least an outer periphery A filling tube in which a substantially disc-shaped partition member made of a porous material having a flexible portion is disposed at a substantially distal end is introduced into the core hole from the side where the partition member is disposed, and the partition member is inserted into the core hole. The filler for filling the core hole is press-fitted from the partition member to the contact surface side through the filling pipe, and the partition member is moved to the opening of the core hole by the pressure of the filler. The core hole is filled with a filler by extruding.

  The component corresponding to the technical idea in the core hole filling apparatus and the description thereof can be applied to the core hole filling method.

  According to the core hole filling device and the core hole filling method of the present invention, even when a highly fluid filler is used, the core hole can be filled without causing a gap without depending on the skill level of the operator. The durability of the building can be ensured and the working time can be shortened.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 is a diagram for explaining a core hole filling apparatus according to the present embodiment. 1 shows a state in which the core hole filling device 200 (hereinafter referred to as the filling device 200) is installed in one of the wall surface 100 and the plurality of core holes 110 included in the wall surface 100. Will be described later.

  As shown in FIG. 1, the filling device 200 includes a filling jig 210, a holding jig 230, and a filler press-fitting device 290.

  The filling jig 210 is a jig that is inserted into the core hole 110 and used for filling the core hole 110 with a filler. FIG. 2 is a diagram illustrating the filling jig 210. 2A is a perspective view of the filling jig 210, and FIG. 2B is a cross-sectional view and a side view of the filling jig 210. As shown in FIG. 2, the filling jig 210 includes a partition wall member 211, a filling tube 220, and a cap 226.

  The partition member 211 is a substantially disk-shaped member for sealing the inside of the core hole 110 when the core hole 110 is filled. The partition member 211 includes a porous portion 212, a first pressing plate 214, and a second pressing plate 216.

  The porous portion 212 is made of a flexible porous material and is a substantially disk-shaped member having a diameter larger than that of the core hole 110, and is disposed at a substantially distal end of a filling tube 220 described later. The porous portion 212 has an insertion hole 212a through which the filling tube 220 is inserted at substantially the center thereof. As a result, the filling tube 220 can be inserted into the insertion hole 212a, and the filler can be filled into the space behind the porous portion 212 of the core hole 110 through the filling tube 220.

  The porous portion 212 has an outer peripheral portion 212b that is a portion positioned outside a first presser plate 214 and a second presser plate 216 described later. In the present embodiment, since the entire porous portion 212 is made of a porous material, the outer peripheral portion 212b is naturally made of a porous material. As described above, since the outer peripheral portion 212 b is made of a porous material, when the partition member 211 is inserted into the core hole 110, the outer peripheral portion 212 b is deformed and is in close contact with the side surface of the core hole 110. The space behind the member 211 is sealed with the porous portion 212.

  Then, when the filler is pressed into the sealed space of the core hole 110 through the filling tube 220, the air in the space is pushed out by the filler, and the space in the sealed space is closed through the pores of the outer peripheral portion 212b (porous material). Driven out. Therefore, since the air in the core hole 110 is expelled and filled with the filler only by press-fitting the filler, there is no air gap in the core hole 110. For this reason, it is possible to fill the core hole 110 without generating a gap without depending on the skill level of the operator, and it is possible to ensure the durability of the building and shorten the work time.

  In addition, since the outer peripheral portion 212b is made of a porous material, the outer peripheral portion 212b can be deformed following the shape even if the side surface of the core hole 110 has an uneven shape. Thereby, since the situation where the partition member 211 is caught by the convex part of the core hole 110 does not occur, the filling device 200 (the partition member 211) smoothly moves in the core hole 110 while being pushed out by the filler. To reach the vicinity of the entrance. Therefore, the core hole 110 can be completely filled.

  In the present embodiment, the partition wall member 211 is configured to have the porous portion 212 in which the outer peripheral portion 212b and all other portions are made of a porous material. However, the present invention is not limited to this. The partition member 211 only needs to have at least the outer peripheral portion 212b made of a porous material. Therefore, for example, a portion other than the outer peripheral portion 212b of the porous portion 212 (partition wall member 211), that is, a portion of the porous portion 212 according to the present embodiment that contacts the first pressing plate 214 or the second pressing plate 216 is made of a hard material. (A material that does not have flexibility), and only the outer peripheral portion 212b may be formed of a porous material. Also by this, the smooth movement in the core hole 110 of the partition member 211 as described above can be enabled.

  However, it is not preferable to configure the outer peripheral portion 212b from a hard material. This is because when the outer peripheral portion 212b is made of a hard material, the outer peripheral portion 212b is caught by the convex portion on the side surface of the core hole 110, the partition wall member 211 cannot move to the inlet side of the core hole 110, and the core hole 110 is completely This is because it will not be filled.

  The first pressing plate 214 and the second pressing plate 216 are substantially disk-shaped members having a diameter smaller than that of the porous portion 212, and an insertion hole 214a and an insertion hole through which the filling tube 220 is inserted at substantially the center thereof. 216a each. Thereby, the filling tube 220 is inserted through the insertion hole 214a and the insertion hole 216a, and the filler can be introduced into the space sealed by the porous portion 212 (partition wall member 211) in the core hole 110.

  Of the two first pressing plates 214 and the second pressing plate 216, the first pressing plate 214 is fixed to the tip of the filling tube 220, and the surface of the porous portion 212 on the inner side of the core hole 110 (the tip side). In contact with the surface). As a result, deformation of the porous portion 212 other than the outer peripheral portion 212b can be prevented using the first pressing plate 214. In detail, the porous part 212 made of a porous material that is flexible as a whole may be deformed by losing the pressure of the filler press-fitted from the filler press-fitting device 290. There is no problem if such deformation occurs only in the outer peripheral portion 212b. However, if the entire porous portion 212 is deformed other than the outer peripheral portion 212b, that is, if the entire porous portion 212 is deformed, a gap is formed between the porous portion 212 and the side surface of the core hole 110. As a result, the filler leaks out from the gap and hinders the filling of the core hole 110.

  Therefore, as in the present embodiment, the first pressing plate 214 is provided on the surface of the porous portion 212 on the back side of the core hole 110. Thereby, since the porous part 212 is supported by the 1st press board 214, it can prevent that the whole porous part 212 deform | transforms and can perform the filling of the core hole 110 suitably.

  The second pressing plate 216 is disposed in contact with the front surface of the porous portion 212. The second pressing plate 216 is fixed to the first pressing plate 214 via the porous portion 212. Thereby, the porous part 212 is fixed to the filling tube 220 in a state of being sandwiched between the first pressing plate 214 and the second pressing plate 216. Therefore, the porous portion 212 (partition wall member 211) can be reliably fixed to the filling tube 220.

  Note that, as described above, the diameters of the first pressing plate 214 and the second pressing plate 216 are smaller than the porous portion 212. Thereby, the contact of the side surface of the core hole 110 with the first pressing plate 214 and the second pressing plate 216 can be avoided. If the diameters of the first pressing plate 214 and the second pressing plate 216 are equal to or larger than the porous portion 212, the side surface of the core hole 110 comes into contact with the first pressing plate 214 and the second pressing plate 216 instead of the porous portion 212. Therefore, the smooth movement of the filling device 200 in the core hole 110 is hindered, which is not preferable.

  However, if the diameters of the first presser plate 214 and the second presser plate 216 are too small than the porous portion 212, the first presser plate 214 and the second presser plate 216 cannot sufficiently exhibit their functions, which is not preferable. . Therefore, the difference between the radius of the first pressing plate 214 and the second pressing plate 216 and the radius of the porous portion 212 should be kept within a certain range, and the difference is preferably about 15 mm to 20 mm. However, the present invention is not limited to this range, and can be appropriately changed according to the diameter of the core hole 110 and the diameter of the porous portion 212 that changes accordingly.

  In addition, the distance between the first pressing plate 214 and the second pressing plate 216 is preferably narrower than the thickness of the porous portion 212, more preferably about 10 mm smaller than the thickness of the porous portion 212. Thereby, the stability of the porous part 212 at the time of being pinched by the 1st press board 214 and the 2nd press board 216 can be ensured more suitably.

  In the present embodiment, the pressing plates are provided on both surfaces of the porous portion 212. However, the present invention is not limited to this, and if the purpose is only to support the porous portion 212, only one of the surfaces is provided. It is enough if it is provided. In addition, when setting it as either one, it is preferable to provide in the surface of the back | inner side of the core hole 110 of the porous part 212. FIG. Thereby, the porous part 212 can be supported suitably.

  Further, unlike the present embodiment, when the partition wall member 211 is formed of a porous member only at the outer peripheral portion and made of a material having no flexibility (hard material) other than the outer peripheral portion, the first member is not necessarily the first. There is no need to provide the pressing plate 214 and the second pressing plate 216. In the present embodiment, the second pressing plate 216 is fixed to the filling tube 220. However, the present invention is not limited to this, and the first pressing plate 214 may be fixed to the filling tube 220.

  The filling tube 220 is a tube that guides the filler to the core hole 110. In the present embodiment, the filling tube 220 is a pipe made of a hard material. Apart from the role of circulating the filler, the filling tube 220 has a role of holding the posture of the partition wall member 211 by being supported by a first holding part 240 and a second holding part 250 described later. That is, when the filling tube 220 is made of a hard material, the filling tube 220 is less likely to be deformed, so that the horizontal state can be easily maintained, and the partition wall member 211 (the porous portion 212 and the porous portion 212) fixed to the filling tube 220 can be maintained. The postures of the first pressing plate 214 and the second pressing plate 216) can be maintained. Therefore, it is possible to prevent the partition member 211 from being inclined in the core hole 110. For this reason, the sealing state in the core hole 110 by the porous part 212 can be maintained suitably, and it becomes possible to fill the core hole 110 reliably.

  In this embodiment, a pipe made of a hard material is used for the filling tube 220. However, the present invention is not limited to this, and a material other than the hard material can also be used. However, when using a material other than a hard material, that is, a soft material, it is preferable to provide another support member or guide member so that the partition wall member 211 maintains a posture orthogonal to the axis of the core hole. .

  In the present embodiment, the filling tube 220 includes a short first filling tube 222 connected to the partition wall member 211 and a long second filling tube 224 that can be screwed into and removed from the first filling tube 222. . Thereby, the portability of the filling tube 220 and by extension the filling device 200 can be improved.

  The first filling tube 222 has the above-described partition wall member 211 attached to the tip, and has a screw portion 222a at the end (the end opposite to the side introduced into the core hole 110). As a result, the second filling tube 224 or the cap 226 described later can be attached to the first filling tube 222.

  One end of the second filling pipe 224 is connected to the first filling pipe 222, and the other end is connected to a hose 290a of a filler press-fitting device 290 described later. The second filling tube 224 has a screw hole portion 224 a on the inner surface of the end portion on the side connected to the first filling tube 222. Thereby, the screw part 222a of the 1st filling pipe | tube 222 and the screw hole part 224a of the 2nd filling pipe | tube 224 can be screwed together, and these can be connected reliably.

  When the partition member 211 is inserted into the inner part of the core hole 110, the filling tube 220 needs to have a certain length in order for the holding jig 230 described later to support the filling tube 220. On the other hand, it is preferable that the filling tube 220 is rather short when curing after filling and during transportation. Therefore, as described above, the filling tube 220 can be divided into the first filling tube 222 and the second filling tube 224, so that it is possible to appropriately handle the filling tube 220 in any state.

  In the present embodiment, the filling tube 220 is composed of two filling tubes including the first filling tube 222 and the second filling tube 224. However, the present invention is not limited to this, and the filling tube 220 may be integrated with these, or may be formed by connecting three or more members. However, if the filling tube 220 is configured so that the first filling tube 222 and the second filling tube 224 are integrated, there is an advantage that the number of parts can be reduced, but the filling material remaining in the entire filling tube 220 after filling is completed. Since the amount increases, there is a disadvantage that the loss amount of the filler increases. Therefore, it is preferable that the filling tube 220 is composed of two or more members as in this embodiment.

  The cap 226 seals the end of the filling tube 220 opposite to the side that is introduced into the core hole 110 (in this embodiment, the end of the first filling tube 222 on which the partition wall member 211 or the like is not mounted). It is a member to stop. Thereby, at the time of curing, it is possible to prevent the filler from flowing out from the end portion on the opposite side to the side introduced into the core hole 110 of the filling tube 220.

  The cap 226 has a screw hole portion 226a that is screwed into the screw portion 222a of the filling tube 220 (in this embodiment, the first filling tube 222) on the inner surface of the opening. Thereby, the screw portion 222a of the first filling tube 222 and the screw hole portion 226a of the cap 226 are screwed together, and the end portion of the filling tube 220 can be easily and reliably sealed.

  In the present embodiment, the cap 226 has the screw hole portion 226a. However, the present invention is not limited to this. For example, when the cap 226 has a shape or size that can prevent the filler from flowing out from the filling tube 220, such as when the inner surface of the opening of the cap 226 has a shape that is in close contact with the end of the filling tube 220, the cap It is not necessary to provide the screw hole portion 226a in 226.

  The holding jig 230 is a jig that is installed on the wall surface 100 and holds the posture of the filling tube 220.
