Description

  The present invention relates to a metal-resin mixed adhesion assistant and a mortar wall construction method for a concrete wall using the metal resin-mix adhesion assistant.

  Conventionally, when forming a concrete wall, both molds facing each other are maintained at a predetermined interval with a plurality of spacer bolts. In such a state, ready-mixed concrete is driven between the two molds and then cured, and then the two molds are removed to form a concrete wall.

  Moreover, since the concrete wall formed in this way is in a state where the formwork has been removed, the appearance of the surface of the concrete wall is not good. For this reason, in order to improve this appearance, a mortar wall is formed on the surface of the concrete wall by applying raw mortar and curing it.

  Here, the mortar wall formed as described above changes over time. Along with this, when the adhesion state of the mortar wall to the surface of the concrete wall deteriorates over time, the mortar wall is easily peeled off from the surface of the concrete wall.

  For this, a mortar bonding aid described in Patent Document 1 below has been proposed. The mortar adhesion assisting tool protrudes from a frustoconical connector portion, a large number of loop-shaped locking portions formed on the small-diameter end surface of the connector portion, and an outer peripheral portion on the large-diameter end surface side of the connector portion. It is formed of a synthetic resin material by a projecting portion provided and an annular support projection extending from the end surface on the small diameter side of the connector portion so as to surround a large number of loop-shaped locking portions.

Japanese Patent No. 3976427

  By the way, in the state where the mortar adhesion aid configured as described above is embedded in the concrete wall, when the mortar wall is formed on the concrete wall via the mortar adhesion aid, the mortar wall And engages with the connector portion of the mortar bonding aid and a number of loop-shaped locking portions.

  However, since the said mortar adhesion auxiliary tool is formed only with the synthetic resin material, it is insufficient in strength. Therefore, depending on the mortar adhesion assisting tool, there arises a problem that the mortar wall cannot be satisfactorily prevented from peeling or falling from the concrete wall.

  Therefore, in order to cope with the above-described problems, the present invention effectively utilizes a metal material to significantly improve the strength, and the metal resin mixed type adhesion assisting device and the metal resin mixed type It aims at providing the construction method of the mortar wall with respect to the concrete wall using the adhesion auxiliary tool.

In solving the above problems, the metal resin mixed-type adhesion assisting device according to the present invention is as described in claim 1.
The cylindrical head portion (110b), the trunk portion (110a) extending coaxially from the cylindrical head portion, and the diameter outwardly from at least one of the opposing end portions of the cylindrical head portion and the trunk portion. A connector (110) formed integrally with a predetermined resin material and an annular flange portion (110c) extending along a direction;
An inner ring (121), an outer ring (122) having an inner diameter larger than the outer diameter of the inner ring, and a metal material together with the inner ring and the outer ring so as to be connected between the inner ring and the outer ring. A ring member (120) comprising a plurality of integrally formed connecting pieces (123);
An annular non-variable wall portion (131, 132, 133) that is coaxially press-fitted into the cylindrical head portion and is seated on the annular flange portion, and an annular end portion opposite to the annular flange portion of the annular non-variable wall portion. An annular wall portion (130a) formed integrally with the predetermined resin material so as to surround the ring member from the outer peripheral side of the annular variable portion (136) protruding in a direction away from the annular flange portion. An annular body (130) provided with
It is made of a metal material so as to have a cylindrical portion (141) and an annular flange portion (142) formed coaxially so as to be integrated with one end portion in the axial direction of the cylindrical portion. With a separate joint (140),
The connector has a large-diameter hole (115b) formed coaxially at the end opposite to the cylindrical head of the body, and the opposite side from the large-diameter hole to the body of the cylindrical head A shaft hole portion (115) configured with a small diameter hole portion (115a) formed coaxially with an inner diameter smaller than the large diameter hole portion is provided so as to extend toward the center portion of the end portion. Become
The separator joint is coaxially press-fitted into the small-diameter shaft hole portion of the connector via the large-diameter hole portion so as to reach the central portion of the opposite end portion of the columnar head at the cylindrical portion, At the annular flange, it is fitted in the large diameter hole of the shaft hole,
The ring member is an inner ring and is coaxially connected to the cylindrical portion of the separator joint at the center of the opposite end portion of the columnar head by welding.

  According to such a configuration, the metal-resin mixed type adhesion assisting device is integrally configured with three separate parts, that is, a connector, a ring member, and an annular body.

  Here, the annular body is formed of a predetermined resin material together with the connector, and the annular body is assembled to the connector by being press-fitted into the cylindrical head portion of the connector at the annular wall portion. ing. On the other hand, the ring member is formed of a metal material together with a separator joint, and the ring member is located at the center of the opposite end of the cylindrical head at the inner ring, and the shaft of the connector. It is coaxially connected to the cylindrical part of the separator joint fitted in the hole by welding.

  Thus, since the ring member is formed of a metal material, together with the separator joint, unlike a predetermined resin material that is a material for forming the connector and the annular body, the ring member is connected to the connector together with the separator joint. Unlike mechanical and annular bodies, it has excellent mechanical strength such as rigidity.

  For example, when a mortar wall is formed on a concrete wall via a metal resin mixed type bonding auxiliary device embedded in a concrete wall, the metal resin mixed type bonding auxiliary device is a ring member and has high mechanical strength such as high rigidity. Due to its nature, it can firmly engage the mortar wall within it.

  Therefore, even in such a state, even if the mortar wall deteriorates over time, for example, the metal resin mixed type adhesion assisting device can be used with the outer ring and each connecting piece under the high mechanical strength by the ring member. The peeling of the wall from the concrete wall can be firmly prevented for a long time.

  Further, the annular body is integrally configured with an annular non-variable wall portion and an annular variable portion as a separate part from the connector. Therefore, the annular mold can be formed with a simple structure together with the connector mold described above. This means that the configuration of the molding die as the whole metal resin mixed type adhesion assisting device is simplified, leading to an improvement in productivity of the metal resin mixed type adhesion assisting device.

  Here, the annular non-variable wall portion of the annular wall is coaxially press-fitted into the cylindrical head and seated on the annular flange portion, and the annular variable portion is opposite to the annular flange portion of the annular non-variable wall portion. It is formed so as to protrude in a direction away from the annular flange portion from the annular end portion on the side.

  Therefore, prior to the formation of the concrete wall, even if the annular variable portion of the annular body is pressed by one of the two molds made of wood or synthetic resin, the annular variable portion will be crushed by the pressure from the mold. Transforms into Accordingly, the mold can uniformly abut on the annular variable portion at the portion facing the annular variable portion. In other words, even if the facing surface of the mold is curved in an uneven shape, the mold is uniformly adhered to the annular variable portion at the facing portion of the facing surface with the annular variable portion. No gap is formed between them.

  As a result, even if the subsequent ready-mixed concrete is driven between the two molds via the metal-resin mixed-type adhesion assisting device, the ready-mixed concrete is formed in the annular variable portion of the annular body of the metal-resin mixed-type adhesion assisting device and one mold. It does not enter the inside of the annular body from between the frame. Therefore, the ring member located inside the annular body can be well shielded from the ready-mixed concrete.

  Based on the above, the metal-resin mixed type adhesion assisting device maintains the adhesive strength (anchor effect) of the mortar wall to the concrete wall well over a long period of time based on the high mechanical strength of the ring member made of metal material. obtain.

And clamping bolts 150 are provided.

  Here, the metal resin mixed-type adhesion assisting device 100 is configured to include a mold clamping bolt 150. However, the mold clamping bolt 150 is only required when clamping the mold as described later. When it is removed, it is removed together with the mold. In such a stage, the metal resin mixed adhesion assisting device 100 is constituted by the connector 110, the octopus leg annular body 130, the ring member 120 and the separator bolt 140.

  From the above, the metal resin mixed type adhesion assisting device 100 may be grasped as a configuration including the connector 110, the ring member 120, the octopus leg annular body 130, and the separator bolt 140.

  In the first embodiment, the basis for forming the ring member 120 with a metal material such as stainless steel is as follows.

  Conventionally, an adhesion assisting device such as an adhesion assisting tool is usually formed of a synthetic resin material in its entire configuration. However, in this case, the adhesion assisting device is insufficient in strength to properly assist the adhesion of the mortar wall to the concrete wall. As a result, when viewed over time, there arises a problem that peeling and falling of the mortar wall from the concrete wall cannot be prevented properly.

  On the other hand, as a result of examining various materials and configurations, the inventor of the present application forms a ring member with a metal material such as stainless steel, thereby preventing the mortar wall from peeling or dropping from the concrete wall over a long period of time. It has been found that the required mechanical strength can be realized by a ring member in a compact configuration.

  As shown in any of FIG. 2 and FIGS. 9 to 11, the annular body 130 is coaxially fitted to the columnar head portion 110 b of the connector 110 by press fitting and is seated on the annular flange portion 110 c. .

It is integrally formed by injection molding.

  The annular wall part 130 a includes an annular seat part 131, an annular thick part 132, and an annular thin part 133. The annular seating portion 131 is coaxially seated on the annular upper surface of the annular flange portion 110c, and the outer diameter of the annular seating surface portion of the annular seating portion 131 is equal to the outer diameter of the annular flange portion 110c. mm). The axial length of the annular seat 131 is 2.5 (mm).

  The annular thick portion 132 is formed so as to extend coaxially upward from the inner peripheral side portion of the upper end portion of the annular seat portion 131, and the thickness, outer diameter, and axial length of the annular thick portion 132. Are 3.2 (mm), 36.1 (mm), and 6.5 (mm), respectively. The inner diameter of the annular thick portion 132 is equal to the inner diameter of the annular seat portion 131.

  Here, the annular seat part 131 and the annular thick part 132 are coaxial with the cylindrical head part 110b under the configuration that can be press-fitted later with respect to the outer diameter of the cylindrical head part 110b. Is set to a value that can be press-fitted. The inner diameters of the annular seat 131 and the annular thick part 132 are set to 29.7 (mm), for example.

  As shown in FIG. 11, the press-fitable structure includes two annular convex portions 132 a and a plurality of shallow rectangular recessed portions 132 b. The two annular convex portions 132 a include an annular seat portion 131 and an annular seat portion 131. The thick part 132 is formed so as to protrude inward from the axially intermediate portion of both inner peripheral surfaces. Each protrusion width of the two annular projections 132a is, for example, 0.2 (mm), and each axial length of the two annular projections 132a is, for example, 0.4 (mm). ). Moreover, the axial direction space | interval of the said 2 cyclic | annular convex part 132a is 3 (mm), for example.

  Further, the plurality of rectangular recesses 132b are formed shallowly over the inner peripheral surfaces of both the annular seating part 131 and the annular thick part 132. The annular seat portion 131 and the annular thick portion 132 may be press-fitted into the cylindrical head portion 110b, and the plurality of rectangular recess portions 132b may be eliminated as necessary. In addition, by setting the inner diameter of the annular seat portion 131 and the annular thick portion 132 and the outer diameter of the cylindrical head portion 110b to be press-fit as described above, two annular convex portions 132a and a plurality of shallow rectangular recess portions Both of 132b may be abolished.

  The annular thin portion 133 is formed so as to extend coaxially upward from the outer peripheral portion of the upper end portion of the annular thick portion 132. The thickness and outer diameter of the annular thin portion 133 are respectively 1. 5 (mm) and 36.1 (mm).

  As illustrated in FIG. 13, the plurality of connecting piece portions 130 b are integrally formed with a rod portion 134 and a ball portion 135, respectively, and each rod portion 134 is an upper end portion of the annular thick portion 132. The inner circumferential portion extends in the circumferential direction at a predetermined angular interval, and in the axial direction of the thick portion 132 is integrally extended in a rod shape obliquely upward at a predetermined inclination angle. Yes. Each sphere part 135 has a predetermined sphere diameter and is coaxially supported by the extending end part of each corresponding rod part 134. Thereby, in each of the plurality of connecting piece portions 130b, the ball portion 135 plays a role of preventing the rod portion 134 from coming out of the mortar wall under an outer diameter larger than the outer diameter of the rod portion 134. It fulfills the function of firmly engaging the mortar wall.

  Here, the number of the plurality of connecting piece portions 130b is 16, and accordingly, the predetermined angular interval is 22.5 degrees. Further, the predetermined inclination angle described above is about 45 degrees with respect to the axial center of the thin portion 123, and the thickness (outer diameter) of each rod portion 134 of the plurality of connecting piece portions 130b is 0.6 (mm). It has become. Moreover, the above-mentioned predetermined spherical diameter is 1.5 (mm). In the first embodiment, hereinafter, the plurality of connecting piece portions 130b are also referred to as circumferential connecting piece portions 130b, respectively.

  In addition, the annular body 130 includes an annular protrusion 136 as shown in any of FIGS. The annular protrusion 136 is made of the above-mentioned predetermined light-resistant pigment-containing resin material in a mountain shape in the longitudinal section so as to extend upward by a predetermined height from the intermediate portion in the width direction of the extending end surface of the annular thin portion 133. Therefore, it is formed integrally with the annular thin portion 133.

  As shown in FIG. 13 or 14, the annular protrusion 136 is integrally formed at the base portion 136 a at the intermediate portion in the width direction of the extended end surface of the annular thin portion 133, and the annular protrusion 136. Extends upward from the base portion 136a into a mountain shape in the longitudinal section.

  In addition, the top portion 136b of the annular protrusion 136 has a radius of curvature of 0.1 (mm) so as to be rounded in the longitudinal section thereof. In the first embodiment, the width of the base portion 136a of the annular protrusion 136 (the width along the width direction of the annular thin portion 133) is 0.5 (mm). The predetermined height is a value within a range of 0.1 (mm) to 2.0 (mm).

  Thereby, in the annular wall portion 130a, when the annular protrusion 136 is pressed toward the annular thin portion 133 as will be described later, the constituent parts of the annular wall portion 130a other than the annular protrusion 136 are not deformed. The shape can be easily deformed. When the annular wall portion 130a is viewed in the radial direction, the annular protrusion 136 is opposed to the center of the spherical portion 135 of each circumferential connection piece 130b at the top portion 136b.

  Here, the grounds for forming the annular protrusion 136 on the annular wall 130a in the metal-resin mixed adhesion assisting device 100 according to the first embodiment will be described.

  Conventionally, when embedding a mortar bonding aid in a concrete wall, as described at the beginning of this specification, in a state where the mortar bonding aid is in contact with one mold frame between both mold frames. The mortar adhesion assistant is clamped between both molds by sandwiching and pressing one of the molds toward the mortar adhesion assistant. Along with this, one mold is pressed against the mortar bonding aid.

  At this time, when the one mold is made of wood, for example, both surfaces of the one mold are usually not uniform planes but often uneven surfaces. Therefore, for example, when the end surface shape of the annular support protrusion that comes into contact with the opposing surface of one mold of the mortar adhesion assisting tool is flat, the end surface of the annular support protrusion of the mortar adhesion assisting tool and the end surface The opposing surface of one formwork does not contact | abut uniformly, and a clearance gap will be formed between both.

  In addition, for example, when the annular support protrusion of the mortar adhesion assisting tool has a sharp cross-sectional shape such as a wedge-like cross section unlike the above, the sharp end of the annular support protrusion is on one side. When the annular groove is formed in the opposing surface of one mold frame by being pushed into the mold frame so as to bite from the opposing surface, the annular groove of the above one mold frame is reused when the subsequent one mold frame is reused. Because of this, the mortar adhesion assistant and one mold cannot contact uniformly, and a gap due to an annular groove is formed between the contact surfaces of the mortar adhesion assistant and one mold. End up.

  In short, the shape of at least one of the annular support protrusion that contacts the opposing surface of one mold frame of the mortar adhesion assisting tool and the opposing surface of the one mold frame is the annular support protrusion of the mortar adhesion assisting tool and one mold frame. If the contact with the opposite surface of the mold is not uniform, the ready-mixed concrete passes between the annular end of the annular support protrusion and the opposite surface of the one mold and adheres to the mortar. It leaks into the annular support protrusion of the auxiliary tool, and the inside of the annular support protrusion of the mortar adhesion auxiliary tool cannot be blocked from the ready-mixed concrete.

  Therefore, in the metal-resin mixed adhesion assisting device 100 according to the first embodiment, the octopus foot annular body 130 is formed integrally with the extended upper end portion of the annular thin portion 133 of the annular wall portion 130a. When one mold frame is pressed and pressed against the octopus foot ring body 130 so as to include the annular protrusion 136, the one mold frame is formed on the annular surface of the annular wall section 130a on the opposite surface. It is pressed toward the extending end of the thin portion 133.

  Here, the annular protrusion 136 of the octopus foot annular body 130 is configured to be easily deformed as described above, so that the annular protrusion 136 also causes deformation of the facing surface of one mold. Without being deformed, it can be easily deformed toward the extending end of the annular thin portion 133 of the annular wall portion 130a.

  Thus, one mold is pressed toward the extending end of the annular thin portion 133 while deforming the annular protrusion 136 so as to be crushed toward the extending end of the annular thin portion 133. . As a result, the deformed annular projection 136 can be uniformly adhered to the facing surface without forming a gap with the facing surface of one mold.

  The above is the basis for providing the annular protrusion 136 on the annular wall 130a of the octopus foot annular body 130 as described above.

  In the first embodiment, the annular protrusion 136 plays a role as an annular variable portion. On the other hand, the annular seat portion 131, the annular thick portion 132, and the annular thin portion 133 are different from the annular protrusion 136 and cannot be deformed. Therefore, the annular non-variable seat portion and the annular non-variable thick portion respectively. And it plays a role as an annular non-variable thin part. The annular non-variable seating portion, the annular non-variable thick portion, and the annular non-variable thin portion are collectively referred to as an annular non-variable wall portion.

The cylindrical portion 141 extends coaxially from the small diameter hole portion 115a of the shaft hole portion 115 to the central portion of the extending end surface of the columnar head portion 110b. This means that the cylindrical portion 141 is located in the central portion of the extended end surface of the columnar head portion 110b at the extended end opening.

  The flange 142 is formed coaxially and integrally with the cylindrical portion 141, and the flange 142 is fitted into the large-diameter hole 115 b of the shaft hole 115 of the connector 110. In addition, the said collar part 142 exhibits the positioning effect | action which positions the extension end opening part of the circular head 141 in the center part of the extension end surface of the cylindrical head part 110b.

  Thus, the separ joint 140 configured as described above is coaxially welded to the inner ring 121 of the ring member 120 from the back side thereof at the extended end opening of the cylindrical portion 141, so that Coaxially connected.

F1 is inserted into the mold clamping nut 170c through a pair of end thick materials 170a and a formwork tension tie 170b which is a so-called foam tie (registered trademark) so as to be detachable.

  Here, the nut 170c is clamped so as to press one mold F toward the metal-resin mixed-type adhesion assisting device 100 via the mold tension fitting 170b and the pair of thick end members 170a. The screw 150 is adjusted with the bolt 150. The spacer bolt 160 is fastened to the other mold F at the other side axial male screw portion.

  As a result, the metal resin mixed adhesion assisting device 100 and the spacer bolt 160 can be held by both molds F at positions corresponding to the through holes F1 of the one mold F. As described above, when one mold F is pressed toward the metal-resin mixed adhesion assistant 100, the annular wall 130a of the metal resin-mix adhesion auxiliary instrument 100 is connected to the one mold F. The annular projection 136 is pressed against the annular projection 136 at a portion corresponding to the annular projection 136.

The material for forming the spacer bolt 160 includes stainless steel. In addition, the pressing force of the nut 170c through the one mold F against the metal resin mixed adhesion assisting device reaches about 200 (kgf / cm ₂ ), that is, 19.6 (MPa). Since the ring member 120 is received by the annular wall portion 130a, the ring member 120 is not crushed by the pressing force.

  Therefore, since the annular protrusion 136 is formed so as to be easily deformed as described above, the annular protrusion 136 is formed so that the annular thin portion 133 is crushed by the pressing force of the one mold F. It is deformed toward the extended end.

  Along with this, the one mold F is not deformed at the contact portion with the annular projection 136 on the inner surface of the one mold F, and the inner wall of the annular thin wall portion of the annular wall portion 130a is formed on the inner surface. The ring-shaped extended end portion can be brought into close contact with each other through the deformed ring-shaped protrusion 136.

  At this time, since one mold F is made of wood or a synthetic resin material, the inner surface of the one mold F does not have a uniform planar shape. Since the annular projection 136 is deformed so as to be crushed as described above, the contact portion of the inner surface of one mold F with the annular projection 136 is not deformed. This is because the tip of the annular protrusion 136 has a rounded cross-sectional shape, so that the contact portion of the inner surface of one mold F with the annular protrusion 136 is further increased. The deformation of can be suppressed. This means that reuse of one mold F can be repeated.

  Thereafter, as described above, one mold F can uniformly contact the annular projection 136 of the annular wall 130a on the inner surface thereof, so that the gap between the one mold F and the annular projection 136 is reached. There are no gaps.

The pressing force of the nut 170c through the one mold F against the metal-resin mixed adhesion assisting device 100 reaches about 200 (kgf / cm ₂ ), that is, 19.6 (MPa). Since the ring wall 120a is received by a portion other than the annular protrusion 136, the ring member 120 and each peripheral connecting piece 130b are not crushed by the pressing force.

  After the processing of the mold clamping bolt fastening step S3, the ready-mixed concrete is driven between the two molds F in the ready-mixed concrete driving step S4. Accordingly, ready-mixed concrete flows between both molds F. Note that ready-mixed concrete refers to concrete that has not yet hardened.

  At this time, the ring member 120 and the plurality of peripheral connection piece portions 130b of the metal resin mixed adhesion assisting device 100 are in an area surrounded by the columnar head portion 110b of the connector 110, the annular wall portion 130a, and the one mold F. Therefore, the ready-mixed concrete does not leak into the region from between the annular protrusion 136 of the annular wall 130a and the inner surface of one mold F. As a result, the ring member 120 and the plurality of peripheral connection piece portions 130b can be reliably isolated from the ready-mixed concrete.

  As described above, when ready-mixed concrete is driven between the two molds F, the ready-mixed concrete fills the area excluding the metal-resin mixed adhesion assisting device 100 in the space area between the two molds. .

  Thereafter, in the next ready concrete hardening waiting step S5, the process waits for a predetermined waiting time until the ready concrete filled between both molds F is hardened. When the ready-mixed concrete hardens in this way, a concrete wall W (see FIG. 20) is formed. At this time, the concrete wall W is formed with a housing hole W1 (see FIG. 21) that houses the metal-resin mixed adhesion assisting device 100.

  In the next mold clamping bolt removing step S6, the nut 170c is detached from the mold clamping bolt 150. Thereafter, the pair of thick end members 170a and the formwork tension fitting 170b are detached from the formwork tightening bolt 150, and the formwork tightening bolt 150 is detached from the separator joint 140.

  At this time, the mold clamping bolt 150 is rotated and detached, but when the detent portion 116 of the connector 110 is engaged with the inner peripheral wall portion of the accommodation hole portion W1 in the concrete wall W, It is kept non-rotatable. For this reason, the metal resin mixed-type adhesion assisting device 100 does not rotate together with the rotation of the mold clamping bolt 150. Further, as shown in FIG. 20, the annular flange portion 110c of the connector 110 is held in the inner peripheral wall portion of the accommodation hole portion W1 in the concrete wall W together with the annular seat portion 131 of the annular body 130. The escape from the accommodation hole W1 of the resin-mixing type adhesion assisting device 100 can be reliably prevented.

  Subsequently, both mold forms F are removed from the concrete wall W in the mold form removing step S7. Along with this, the concrete wall W is released from both molds F in a state where the metal resin mixed type adhesion assisting device 100 is accommodated in the accommodation hole W1 as shown in FIG. At this time, the metal-resin mixed adhesion assisting device 100 is supported by one axial male screw portion of the spacer bolt 160 by the separator bolt 140 in the accommodation hole W1.

  When the housing of the metal resin mixed adhesion assisting device 100 with respect to the concrete wall W is completed as described above, in the next raw mortar coating step S8, the raw mortar has a predetermined thickness as shown in FIG. It is applied over the entire surface W2 of the concrete wall W. In addition, raw mortar means mortar which has not yet hardened.

  At this time, the application is performed so as to cover the metal-resin mixed adhesion assisting device 100 on the surface of the concrete wall W. Therefore, the metal-resin mixed adhesion assisting device 100 is embedded in the concrete wall W with raw mortar while being accommodated in the accommodation hole W1 of the concrete wall W.

  Along with this, the raw mortar enters the inside of the annular wall portion 130a of the metal resin mixed adhesion assisting device 100. Next, the raw mortar that has entered in this way further enters the extended end face of the cylindrical head portion 110b of the connector 110 via the ring member 120 and the plurality of peripheral side connecting piece portions 130b.

  Here, as described above, the raw mortar that penetrates toward the extending end surface of the columnar head portion 110b of the connector 110 via the plurality of peripheral side connection piece portions 130b and the ring member 120 is the plurality of peripheral side connection piece portions 130b. And passes between the ring members 120 and reaches the extended end surface of the cylindrical head portion 110b.

  In addition, the ready-mixed concrete that reaches the extending end surface of the columnar head portion 110b reaches the inside of each recess 113 formed on the extending end surface of the columnar head portion 110b. This means that the ready-mixed concrete extends between the ring members 120 facing each other and the inner surface of the recess 113. Therefore, the amount of raw mortar that enters between the ring member 120 and the extended end face of the cylindrical head portion 110b is increased by forming the plurality of recesses 113 on the extended end face of the cylindrical head portion 110b.

  After the raw mortar application step S8 as described above, in the next raw mortar curing waiting step S9, the process waits for a predetermined waiting time until the raw mortar applied to the surface W2 of the concrete wall W is cured as described above. Accordingly, when the raw mortar is cured, a mortar wall M is formed on the surface W2 of the concrete wall W.

  As described above, in the first embodiment, the metal-resin mixed type adhesion assisting device 100 is configured by three components, that is, the connector 110, the ring member 120, and the annular body 130.

  Here, the connector 110 and the annular body 130 are formed of a predetermined light-resistant pigment-containing resin material in which the light-resistant black pigment is uniformly contained in nylon 6, whereas the ring member 120 is formed of the connector 110. Unlike the annular body 130, it is made of stainless steel SUS304.

  Therefore, in the metal-resin mixed adhesion assistant 100, the ring member 120 has higher rigidity than the resin material such as the above-mentioned light-resistant pigment-containing resin material, as will be described later. The instrument 100 can exhibit high mechanical strength by the ring member 120 as compared with a mortar adhesion aid made of only a synthetic resin material.

  Further, in the state where the metal resin mixed adhesion assisting device 100 press-fits the annular wall portion 130a of the annular body 130 into the columnar head portion 110b of the connector 110 as described above, the annular protrusion portion 136 of the annular wall portion 130a is used. A spacer joint 140 is connected to a spacer bolt 160 extending from the one mold side to the other form side so as to face one of the two form frames F. Further, the metal-resin mixed adhesion assisting device 100 is pressed toward the connector 110 through the one mold frame while being deformed so as to crush the annular protrusion 136 at the annular wall portion 130a. Such a pressing force is received by the annular flange portion 110b via the annular wall portion 130a.

  As a result, in the metal-resin mixed adhesion assisting device 100, the deformation of the annular protrusion 136 described above is caused by the deformation of components other than the annular protrusion 136 of the annular wall 130a and the annular wall of one mold F. The annular wall portion 130a forms a sealed space together with the connector 110 and one mold frame, and a plurality of circumferential sides are provided in the sealed space. The connection piece 130b and the ring member 120 are confined.

  Therefore, even if the ready-mixed concrete is driven between the two molds F as described above, the plurality of peripheral connecting piece portions 130b and the ring member 120 are well isolated from the ready-mixed concrete. The side connecting piece 130b and the ring member 120 are not reached. This means that the plurality of peripheral side connecting piece portions 130b and the ring member 120 can be in good contact with the raw mortar without being contaminated with the ready-mixed concrete.

  In addition, as described above, the portion of the annular wall portion 130a excluding the annular projection portion 136 is not deformed by pressing with one mold, so that the plurality of peripheral side connecting piece portions 130b and the ring member 120 are The original shape can be satisfactorily maintained in the above-described sealed space.

  Therefore, as described above, the raw mortar is applied to the surface W2 of the concrete wall W via the metal resin mixed adhesion assisting device 100, so that the raw mortar is surrounded by a plurality of circumferences of the metal resin mixed adhesion assisting device 100. The side connecting piece 130b and the ring member 120 can be satisfactorily engaged. This means that the plurality of peripheral side connecting pieces 130b and the ring member 120 of the metal resin mixed adhesion assisting device 100 can be firmly engaged with the mortar wall M formed after the raw mortar is hardened. Means.

  As a result, the metal-resin mixed type adhesion assisting device 100 favorably assists the adhesion of the mortar wall M to the concrete wall W with the plurality of peripheral connection pieces 130b and the ring member 120, and the concrete wall of the mortar wall M The adhesion force (anchor effect) to W can be improved satisfactorily.

  In addition, the metal resin mixed adhesion assisting device 100 is continuously removed as it is without being removed while being connected to the spacer bolt 160 by the separator bolt 140 even after the removal by removing the both molds F as described above. Maintained. Here, the ring member 120 is connected to the small diameter portion 141 of the separator bolt 140 by welding at the inner ring 121 thereof. As a result, in the metal-resin mixed adhesion assisting device 100, the ring member 120 can be coaxially and mechanically firmly connected to the spacer bolt 160 via the separator joint 140. This is because the metal-resin-mixed adhesion assisting device 100 is connected from the concrete wall W of the mortar wall M by a coaxial connection with a high mechanical strength of the ring member 120 made of a metal material, the separator joint 140, and the spacer bolt 160. It means that peeling and dropping can be well prevented over a long period of time.

  Here, since the metal resin mixed adhesion assisting device 100 only protrudes from the surface W2 of the concrete wall W at the plurality of peripheral connection piece portions 130b, the coating thickness of the raw mortar is almost equal to the concrete wall. Since it can be kept as uniform as possible over the surface of W, it can be made as thin as possible, which helps to reduce the coating amount of raw mortar.

  As described above, not only one metal resin mixed adhesion assistant device 100 but also each remaining metal resin mixed adhesion assistant device 100 is dispersed and embedded between the concrete wall W and the mortar wall M. Thus, each metal resin mixed adhesion assisting device 100 can enhance the anchor effect of the mortar wall M on the concrete wall W with the ring member 120 and the plurality of peripheral side connecting pieces 133b.

  This is because the mortar wall M is not peeled off or dropped from the concrete wall W under the strong anchor effect by the adhesion assistance by each metal resin mixed adhesion assisting device 100 having the ring member 120 made of a metal material. It means that the adhesion to the surface W2 of the concrete wall W can be maintained well over a long period of time.

  Moreover, in this 1st Embodiment, each metal resin mixing type | mold adhesion auxiliary instrument 100 is comprised by three components by the separate body of the connector 110, the ring member 120, and the annular body 130. FIG. Here, in the connector 110, the frustoconical body 110a is configured so as to be tapered toward the axial direction away from the annular flange 110c. Compared with the case where the portion 110a is configured to expand toward the end in the axial direction away from the annular flange portion 110c, a simpler configuration is sufficient. Accordingly, the mass productivity of the connector 110 is improved. In addition, such a thing can be further improved because the rotation prevention part 116 protrudes from the large-diameter side outer peripheral surface part of the truncated cone body part 110a along the lower surface of the annular flange part 110c.

  In addition, each metal resin mixed type adhesion assisting device 100 has a separator joint 140 that is coaxially press-fitted into the connector 110 for connection to the spacer bolt 160. The connection with can be made firmly.

  Here, since the ring member 120, the separator joint 140, and the spacer bolt 160 are all formed of a metal material, the ring member 120, the separator joint 140, and the spacer bolt 160 are mechanically high in rigidity and the like. Has strength. Moreover, as described above, the ring member 120 is coaxially connected to the separator joint 140 by welding, and the spacer bolt 160 is coaxially attached to the female screw hole 140a of the separator joint 140.

  Accordingly, each metal resin mixed adhesion assisting device 100 can be firmly supported by the ring bolt 120 and the separator joint 140 by the spacer bolt 160 under high mechanical strength. This means that each metal resin mixed adhesion assistant device 100 can greatly improve the anchor effect of the mortar wall M on the concrete wall W compared to the adhesion assistant device made of only a synthetic resin material.

  Further, each metal resin mixed-type adhesion assisting device 100 uses the mold clamping bolt 150 as an auxiliary part, and therefore, it is not necessary to separately prepare the mold clamping bolt and is convenient. It is convenient to prepare a plurality of clamp bolts 150 having different overall lengths.

  Further, in each metal resin mixed type adhesion assisting device 100, the connector 110 and the annular body 130 are formed of a predetermined light-resistant pigment-containing resin material in which the light-resistant black pigment is uniformly contained in nylon 6. The connector 110 and the annular body 130 can be maintained in good quality without being deteriorated over a long period of time even when receiving external light such as ultraviolet rays.

  Furthermore, since the nylon 6 has a good elongation characteristic with respect to the pulling force, even if a situation occurs in which the mortar wall tends to peel off the surface of the concrete wall, the peripheral side connecting piece portion 130b of the annular body 130 is By extending with good engagement between the corresponding internal parts of the mortar wall, it is possible to prevent the mortar wall from falling off due to the high mechanical strength of the ring member 120.

  Therefore, the adhesive strength of the mortar wall to the concrete wall can be well maintained over a long period of time, coupled with the light resistance of the connector and the annular body by the light-resistant black pigment.

As can be seen from the above-described metal resin mixed adhesion assistant device 100 and the process of FIG. 19, it is not necessary to repeat the removal operation and new attachment operation of the metal resin mixed adhesion assistant device 100, thereby improving workability. Needless to say, it is possible to prevent the occurrence of environmental pollution problems caused by the disposal of each metal resin mixed type adhesion assisting device 100.

  In each of the plurality of connecting pieces 124, the rising portion 124b rises from the extended end portion of the corresponding base end portion 124a to the surface side of the inner ring 121 at a predetermined rising angle β (see FIG. 24). It is extended to. Here, as shown in FIG. 24, the above-described predetermined rising angle β is a rising angle of the rising portion 124b with respect to the radial direction of the inner ring 121, and is set to 90 degrees in the second embodiment.

  Further, in each of the plurality of connecting pieces 124, the tip end portion 124c extends radially outward from the extending end portion of the corresponding rising portion 124b so as to be parallel to the surface of the inner ring 121. . In the second embodiment, the height of the front surface portion 124c from the back surface of the inner ring 121 (see FIG. 24) is the same as the height H (see FIG. 3) described in the first embodiment. It is set to 5 (mm). The connecting piece 124 has the same thickness as the inner ring 121.

  In the second embodiment, the outer ring 122 is integrally connected to the extended end portion of each tip end portion 124c of the plurality of connecting pieces 124 at the inner peripheral portion thereof. Here, the inner peripheral portion of the outer ring 122 is formed integrally with the extended end portion of each tip portion 124c of the plurality of connecting pieces 124 at equal angular intervals in the circumferential direction.

  In the second embodiment, the shape of the outer ring 122 and the connecting pieces 124 is different from the shape of the outer ring 122 and the connecting pieces 123 described in the first embodiment, but the first embodiment. In the same manner as the above, it has a rigidity capable of entering into the raw mortar and has a breaking strength that can support the mortar wall M after the raw mortar is cured.

  The ring member 120a configured as described above is welded coaxially to the inner ring 121 from the back surface side at the extended end opening of the cylindrical portion 141 of the separator joint 140 described in the first embodiment. As a result, the separator joint 140 is coaxially connected. Other configurations are the same as those in the first embodiment.

  In the second embodiment configured as described above, the metal-resin mixed type adhesion assisting device 100 is configured by three components of the connector 110, the ring member 120 a, and the annular body 130. Here, unlike the forming material of the connector 110 and the annular body 130, the ring member 120a is formed of stainless steel SUS304, similarly to the ring member 120 described in the first embodiment.

  Although the ring member 120 a has a different configuration from the ring member 120, the ring member 120 a has high rigidity like the ring member 120. Therefore, the metal resin mixed type adhesion assisting device 100 according to the second embodiment differs from the ring member 120 in the configuration of the ring member 120a, but the metal resin mixed type adhesion assist device described in the first embodiment. Similar to the instrument 100, mechanically high strength can be exhibited as compared to a mortar adhesion aid made of only a synthetic resin material.

Even when the ready-mixed concrete is driven between the two molds F in the confined state, the plurality of peripheral connecting piece portions 130b and the ring member 120a are well isolated from the ready-made concrete. The ready-mixed concrete does not reach the plurality of peripheral side connecting piece portions 130b and the ring member 120a. This means that the plurality of peripheral connecting piece portions 130b and the ring member 120a can be in good contact with the raw mortar without being contaminated with the ready-mixed concrete, substantially as in the first embodiment.

  In addition, as described in the first embodiment, the portion of the annular wall portion 130a excluding the annular protrusion 136 is not deformed by pressing with one mold, so that a plurality of peripheral connection piece portions are provided. The original shape of 130b and the ring member 120a can be well maintained in the above-described sealed space.

  Therefore, when the raw mortar is applied to the surface W2 of the concrete wall W through the metal resin mixed adhesion assisting device 100 as in the first embodiment, the raw mortar is applied to the metal resin mixed adhesion assisting device 100. The plurality of peripheral coupling pieces 130b and the ring member 120a can be satisfactorily engaged. This means that the plurality of peripheral side connecting piece portions 130b and the ring member 120a of the metal resin mixed adhesion assisting device 100 can firmly engage with the mortar wall M formed after the raw mortar is hardened. Means.

  As a result, the metal-resin mixed adhesion assisting device 100 in the second embodiment favorably assists the adhesion of the mortar wall M to the concrete wall W with the plurality of peripheral side connecting piece portions 130b and the ring member 120a. The adhesion force (anchor effect) of the mortar wall M to the concrete wall W can be improved satisfactorily. Other functions and effects are the same as those of the first embodiment.
