Description

The present invention relates to a metal-resin composite type adhesive assisting device.

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

Further, since the concrete wall formed in this way is in a state where the formwork is only removed, the appearance of the surface of the concrete wall is not good. Therefore, in order to improve this appearance, a mortar wall is formed on the surface of the concrete wall by applying fresh mortar and hardening the mortar.

Here, the mortar wall formed as described above changes over time. Along with this, when the adhesive state of the mortar wall to the surface of the concrete wall deteriorates over time, the mortar wall tends to peel off from the surface of the concrete wall.

To this end, the mortar adhesion assisting tool described in Patent Document 1 below has been proposed. The mortar bonding auxiliary tool protrudes into a truncated cone-shaped connector portion, a large number of loop-shaped locking portions formed on the small-diameter side end face of the connector portion, and an outer peripheral portion of the connector portion on the large-diameter side end face side. It is formed of a synthetic resin material by a convex portion provided and an annular support protrusion extending from an 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 a state where the mortar bonding auxiliary tool configured as described above is embedded in the concrete wall, when the mortar wall is formed on the concrete wall via the mortar bonding assisting tool, the mortar wall is inside the concrete wall. At the same time, it engages with the connector part of the mortar adhesive auxiliary tool and a large number of loop-shaped locking parts.

However, since the mortar adhesion assisting tool is formed only of a synthetic resin material, its strength is insufficient. Therefore, depending on the mortar adhesion assisting tool, there arises a problem that the mortar wall cannot be satisfactorily peeled off or dropped from the concrete wall.

Therefore, in order to deal with the above, the present invention effectively utilizes both the metal properties such as the mechanical strength property of the metal material and the resin properties such as the elongation property of the resin material to make the mortar wall. An object of the present invention is to provide a metal-resin composite type adhesive assisting device that prevents peeling or falling from a concrete wall.

In solving the above problem, the metal resin composite type adhesive assisting device according to the present invention is according to the description of claim 1.
A truncated cone-shaped body portion (110a) formed in a truncated shape from the large-diameter side end portion to the small-diameter side end portion, and the truncated cone-shaped body portion from the large-diameter side end portion to the small-diameter side end portion. A cylindrical head (110b) extending coaxially in the direction opposite to the above, and at least one of the truncated cone-shaped body and the opposite ends of the columnar head outward in a radial direction. The extending annular flange portion (110c) and the plurality of surface-side engaging pieces (110d) protruding in a distributed manner from the extending end portion of the columnar head are integrally formed of a predetermined resin material. The formed connector (110) and
An annular non-variable wall portion (141, 142, 143) coaxially press-fitted into the cylindrical head and seated on the annular flange portion, and an annular portion of the annular non-variable wall portion on the opposite side of the annular flange portion. The annular variable portion (146) protruding from the end portion in the direction away from the annular flange portion is integrally formed of the predetermined resin material so as to surround the plurality of surface-side engaging pieces from the outer peripheral side thereof. An annular body (140) provided with an annular wall portion (140a) formed in
Together with the inner ring (121), the outer ring (122) having an inner diameter larger than the outer diameter of the inner ring, and the inner ring and the outer ring so as to be connected between the inner ring and the outer ring. A ring member (120, 120a) including a plurality of connecting pieces (123, 124) integrally formed of a metal material, and a ring member (120, 120a).
It is formed of a metal material so as to have a cylindrical portion (131) and an annular flange portion (132) formed coaxially so as to be integrated with one axial end of the cylindrical portion. Equipped with a sepa joint (130),
The connector is provided with a shaft hole portion (115) formed coaxially over each central portion of the cylindrical head portion and the truncated cone-shaped body portion.
The ring member is surrounded by the annular wall portion of the annular body together with the plurality of surface-side engaging pieces from the outer peripheral side thereof, and the truncated cone-shaped body portion of the shaft hole portion of the connector is surrounded by the inner ring. It is placed coaxially on the opening (115a) on the opposite side of the hole.
In the separable joint, the inner ring of the ring member is sandwiched by the annular flange portion on the opening portion on the opposite side of the shaft hole portion of the connector, and the inner ring of the connector is passed through the inner ring portion of the connector. It is fitted into the shaft hole by press fitting.

According to such a configuration, the metal-resin composite type adhesive assisting device is integrally composed of four separate parts of a connector, a ring member, a sepa joint, and an annular body.

Here, the annular body is formed of a predetermined resin material having excellent resin properties such as elongation characteristics together with the connector, and the annular body is press-fitted into the columnar head of the connector at the annular wall portion thereof. By doing so, it is attached to the connector.

On the other hand, the ring member is formed of a metal material together with the sepa joint, and the ring member is placed on the opening on the opposite side of the cylindrical head by the inner ring, and the sepa joint is an annular collar. The inner ring of the ring member is press-fitted into the shaft hole portion of the connector via the inner ring at the cylindrical portion so as to sandwich the inner ring of the ring member on the opening on the opposite side of the shaft hole portion of the connector.

As a result, in the metal-resin composite type adhesive auxiliary device, the annular body is formed into the cylindrical head of the connector under the combination of the connector and the annular body made of a predetermined resin material and the ring member and the sepa joint made of the metal material. It is press-fitted and the inner ring of the ring member is sandwiched over the opening on the opposite side of the shaft hole of the connector by the annular flange of the sepa joint, and the cylindrical part of the sepa joint is inserted into the shaft hole of the connector via the inner ring. By fitting by press fitting, it is possible to secure a coaxial and strong connection between the ring member and the sepa joint.

Further, as described above, as a resin based on a material for forming a plurality of surface-side engaging pieces of the connector under a combination of a connector made of a predetermined resin material, an annular body, a ring member made of a metal material, and a sepa joint. By utilizing the synergistic property of, for example, the elongation property and the mechanical strength property as a metal based on the material for forming the ring member, it is possible to prevent the mortar wall from peeling or falling from the concrete wall.

For example, when a mortar wall is formed on a concrete wall via a metal-resin composite type adhesive auxiliary device embedded in the concrete wall, the metal-resin composite type adhesive auxiliary device has a plurality of surface-side engaging pieces and ring members of the connector. Can engage tightly inside the mortar wall.

Therefore, in such a state, even if the mortar wall tries to peel off from the surface of the concrete wall due to its deterioration over time, or even if it tries to fall, the load or mortar when the mortar wall tries to peel off occurs. If the load when the wall is about to fall is about 10 (kgf) or less, the mortar wall can be prevented from peeling or falling even with the ring member alone. In addition to this, the plurality of surface-side engaging pieces of the connector, in combination with the mechanical strength characteristics of the ring member due to the resin characteristics such as its elongation characteristics, further prevent the mortar wall from peeling off or falling. obtain.

Further, when the load when the mortar wall is about to peel off or the load when the mortar wall is about to fall becomes larger than the initial load, the plurality of surface-side engaging pieces of the connector are subject to the extension characteristics. In addition, instead of the ring member, the mortar wall can be further prevented from peeling or falling.

Based on the above, the metal-resin composite type adhesive assisting device has resin characteristics centered on the high mechanical strength of ring members and sepa joints made of metal materials and the extension characteristics of multiple surface-side engaging pieces of connectors. Based on the synergistic characteristics, it withstands a wide range of loads caused by peeling and falling of the mortar wall, maintains good adhesive strength (anchor effect) of the mortar wall to the concrete wall for a long period of time, and peels and falls of the mortar wall. Can be prevented even more for a long period of time.

Further, the annular body is integrally formed of an annular non-variable wall portion and an annular variable portion as separate parts from the connector. Therefore, the molding die for the annular body can be formed with a simple structure together with the molding die for the connector described above. This means that the structure of the molding die as a whole of the metal-resin composite type adhesive assisting device is simplified, which leads to an improvement in the productivity of the metal-resin composite type adhesive assisting device.

Here, the annular non-variable wall portion of the annular wall is coaxially press-fitted into the columnar 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 project from the annular end portion on the side in the direction away from the annular flange portion.

Therefore, even if the annular variable portion of the annular body is pressed by one of the two forms made of wood or synthetic resin prior to the formation of the concrete wall, the annular variable portion is crushed by the pressing from the formwork. It transforms like this. Therefore, the mold can uniformly contact the annular variable portion at the portion facing the annular variable portion on the facing surface. In other words, even if the facing surface of the mold is curved in an uneven shape, the mold uniformly adheres to the annular variable portion at the portion facing the annular variable portion and the annular variable portion. No gap is formed between and.

As a result, even if the ready-mixed concrete is subsequently driven between the two formwork via the metal-resin composite type adhesive assisting device, the ready-mixed concrete is one with the annular variable portion of the annular body of the metal-resin composite type adhesive assisting device. It does not invade the inside of the ring from between it and the mold. Therefore, the ring member located inside the annular body and the plurality of surface-side engaging pieces can be well shielded from the ready-mixed concrete.

Therefore, the driven raw mortar adheres well to both the ring member and the plurality of surface-side engaging pieces, and after that, after the mortar wall is formed by hardening, the mortar wall is peeled off as described above. Even if a drop is about to occur, the peeling or dropping causes both the resin characteristics such as the elongation characteristics of the plurality of surface-side engaging pieces and the mechanical strength characteristics of the ring member, or the extension characteristics of the plurality of surface-side engaging pieces. With resin properties such as, it can be prevented for a long period of time.

The surface is semi-oblong and concave (see FIG. 5 or 6).

Here, as shown in FIG. 7, the central concave portion 114 is formed at the extending end portion 113 of the columnar head 110b so as to have a symmetrical concave shape with respect to the illustrated vertical center line. .. Further, the recesses 114 located on the right outer side, the right middle side, and the right inner side in FIG. 7 are the recesses 114 on the left outer side, the left middle side, and the left inner side with reference to the vertical center line shown in FIG. It is formed in a concave shape on the extending end 113 of the columnar head 110b at a position symmetrical with the above.

This means that the plurality of connecting pieces 123 connect the outer ring 12 to the inner ring 121.

Here, the configuration of the plurality of connecting pieces 123 will be described in detail. The plurality of connecting pieces 123 are composed of an even number of connecting pieces 123 (eight in the first embodiment), and the plurality of connecting pieces 123. Each of 123 is integrally configured with a base end portion 123a, an inclined portion 123b, and a tip end portion 123c (see FIGS. 8 and 9).

In the plurality of connecting pieces 123, each base end portion 123a extends outward along the radial direction from the outer peripheral portion of the inner ring 121 along the circumferential direction at equal angular intervals.

Further, in each of the plurality of connecting pieces 123, the inclined portion 123b is inclined so as to extend from the extending end portion of the corresponding base end portion 123a to the surface side of the inner ring 121 at a predetermined inclination angle. .. The predetermined tilt angle described above refers to the tilt angle of the tilt portion 123b with respect to the radial direction of the inner ring 121, and is set to 45 degrees in the first embodiment. Further, the distance along the surface of the inner ring 121 between the extending ends of both inclined portions 123b facing each other in the radial direction of the inner ring 121 is set to 23.3 (mm).

Further, in each of the plurality of connecting pieces 123, the tip portion 123c extends outward from the extending end portion of the corresponding inclined portion 123b so as to be parallel to the surface of the inner ring 121.

Specifically, the outer ring 122 has each tip portion 123c of the plurality of connecting pieces 123 at each corresponding portion to the extending end portion of each tip portion 123c of the plurality of connecting pieces 123 in the inner peripheral portion thereof. It is integrally formed with the extending end portion of each of the tip portions 123c in the same plane as the above.

Further, in the first embodiment, the grounds for forming the ring member 120 with a steel plate material made of stainless steel are as follows.

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

On the other hand, as a result of examining various materials and configurations, the inventor of the present application formed the ring member 120 with a steel plate material made of stainless steel to prevent the mortar wall from peeling or falling from the concrete wall for a long period of time. It has been found that the mechanical strength required for the above can be realized by the ring member 120 in a compact configuration.

In particular, in the first embodiment, the ring member 120 is formed of a steel plate material made of stainless steel as described above. Therefore, the ring member 120 is not only mechanically strong to prevent the above-mentioned mortar wall from peeling or falling from the concrete wall for a long period of time, but also does not rust due to salt damage and is resistant to heating due to fire. It also maintains good mechanical strength without damaging the original shape, and also plays a role of preventing the mortar wall from peeling or falling from the concrete wall for a long period of time. The same applies to the sepa joint 130 and the spacer bolt 160.

In addition, when the mortar wall is adhered to the surface of the concrete wall with an adhesive, the adhesive melts due to the heat of the fire or deteriorates due to salt damage, and the mortar wall is separated from the concrete wall. There is a problem that the mortar wall is peeled off and then dropped. In order to hold the mortar wall on the surface of the concrete wall, instead of the adhesive, the metal-resin composite type adhesive assist according to the first embodiment is used. It can be surely solved by using an instrument.

The separable joint 130 is made of stainless steel, and as shown in FIG. 3, the separable joint 130 is connected to the connector 110 from the extending end 113 side of the columnar head 110b via the ring member 120 and the seating portion 116. It is fitted into the shaft hole portion 115 by press fitting.

The separate joint 130 has a cylindrical shape, and the hollow portion of the separate joint 130 is formed as a female screw hole portion 130a (see FIG. 11). A spacer bolt 160 (see FIG. 19) is screwed into the female screw hole portion 130a from the truncated cone-shaped body portion 110a side of the connector 110. The surface of the sepa joint 130 is nickel-plated.

The separable joint 130 is composed of a cylindrical portion 131 and an annular flange portion 132 as shown in any of FIGS. 3, 4, 11, and 12. As illustrated in FIG. 3, the cylindrical portion 131 passes through the hollow portion of the inner ring 121 of the ring member 120 and the central portion of the bottom surface portion 116a of the seating portion 116 of the cylindrical head 110b and inside the shaft hole portion 115 of the connector 110. It is coaxially fitted to the head by press fitting.

The annular flange portion 132 is formed coaxially and integrally with the cylindrical portion 131, and the annular collar portion 132 is seated on the bottom surface portion 116a of the seating portion 116 via the inner ring 121 of the ring member 120. Therefore, the inner ring 121 is pressed against the bottom surface portion 116a of the seating portion 116. Here, the annular collar portion 132 is housed in the seating portion 116, and the upper end surface of the annular collar portion 132 is a seating portion rather than the extending end surface portion of the extending end portion 113 of the columnar head 110b. It is located on the bottom surface 116a side of the 116.

As shown in any of FIGS. 1 to 4 and 13 to 17, the annular body 140 is coaxially press-fitted into the cylindrical head 110b of the connector 110 and seats on the annular flange portion 110c. It has become like.

Therefore, it is integrally formed by injection molding.

The annular wall portion 140a includes an annular seating portion 141, an annular thick portion 142, and an annular thin wall portion 143. The annular seating portion 141 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 141 is equal to the outer diameter of the annular flange portion 110c, which is 38.5 ( mm). The axial length of the annular seating portion 141 is 2.5 (mm).

The annular thick portion 142 is formed so as to coaxially extend upward from the inner peripheral side portion of the upper end portion of the annular seat portion 141, and the wall thickness, outer diameter, and shaft length of the annular thick portion 142 are formed. Are 3.2 (mm), 36.1 (mm) and 6.5 (mm), respectively. The inner diameter of the annular thick portion 142 is equal to the inner diameter of the annular seating portion 141.

Here, the annular seating portion 141 and the annular thick-walled portion 142 are coaxial with the cylindrical head 110b at their respective inner diameters under a structure that can be press-fitted with respect to the outer diameter of the cylindrical head 110b, which will be described later. It is set to a value that can be press-fitted. The inner diameters of the annular seating portion 141 and the annular thick wall portion 142 are set to, for example, 29.7 (mm).

As shown in FIG. 15, the press-fitting structure includes two annular protrusions 142a and a plurality of shallow rectangular recesses 142b, and the two annular protrusions 142a have an annular seating portion 141 and an annular seating portion 141. It is formed so as to project inward from an axially intermediate portion of both inner peripheral surfaces of the thick portion 142. The protruding width of the annular convex portion 142a of the two articles is, for example, 0.2 (mm), and the axial length of the annular convex portion 142a of the two articles is, for example, 0.4 (mm). ). Further, the axial distance between the annular convex portions 132a of the two articles is, for example, 3 (mm).

Further, the plurality of rectangular recessed portions 142b are formed shallowly over the inner peripheral surfaces of both the annular seating portion 141 and the annular thick-walled portion 142. The annular seating portion 141 and the annular thick-walled portion 142 may be press-fitted into the columnar head 110b, and a plurality of rectangular recessed portions 142b may be abolished as necessary. Further, by setting the inner diameters of the annular seating portion 141 and the annular thick wall portion 142 and the outer diameter of the cylindrical head 110b so as to be press-fitted as described above, the two annular convex portions 142a and the plurality of shallow rectangular recessed portions are formed. Both 142b may be abolished.

The annular thin-walled portion 143 is formed so as to coaxially extend upward from the outer peripheral portion of the upper end portion of the annular thick-walled portion 142, and the wall thickness and outer diameter of the annular thin-walled portion 143 are 1. It is 5 (mm) and 36.1 (mm).

As illustrated in either FIG. 15 or FIG. 16, the plurality of engaging piece portions 140b are integrally formed by the rod portion 144 and the ball portion 145, respectively, and each rod portion 144 has an annular thickness. It extends from the inner peripheral portion of the upper end portion of the meat portion 142 at a predetermined angular interval in the circumferential direction, and is integrally obliquely upward with a predetermined inclination angle in the axial direction of the thick portion 142. It extends like a rod. Further, each ball portion 145 has a predetermined ball diameter and is coaxially supported by the extending end portion of each corresponding rod portion 144. As a result, in each of the plurality of engaging piece portions 140b, the ball portion 145 plays a role of preventing the rod portion 144 from coming off from the mortar wall under an outer diameter larger than the outer diameter of the rod portion 144. , Serves a function of tightly engaging with the mortar wall.

Here, the number of the plurality of engaging piece portions 140b is 16, and the predetermined angular interval described above is 22.5 degrees accordingly. Further, the predetermined inclination angle described above is about 45 degrees with respect to the axial center of the thin-walled portion 143, and the thickness (outer diameter) of each rod portion 144 of the plurality of engaging piece portions 140b is 0.6 (mm). ). Further, the predetermined ball diameter described above is 1.5 (mm). In the first embodiment, hereinafter, the plurality of engaging piece portions 140b are also referred to as peripheral side engaging piece portions 140b, respectively.

Further, the annular body 140 includes an annular protrusion 146 as shown in any of FIGS. 13 to 17. The annular protrusion 146 has a vertical cross-sectional mountain shape and is made of the above-mentioned predetermined light-resistant pigment-containing resin material so as to extend upward by a predetermined height from an intermediate portion in the width direction of the extending end surface of the annular thin-walled portion 143. Therefore, it is integrally formed with the annular thin-walled portion 143.

As shown in FIG. 17, the annular protrusion 146 is integrally formed at the base portion 146a at the intermediate portion in the width direction of the extending end surface of the annular thin-walled portion 143, and the annular protrusion 146 is formed at the base portion. It extends upward from 146a in a mountain shape with a vertical cross section.

The top portion 146b of the annular protrusion 146 has a radius of curvature of 0.1 (mm) so as to be rounded in its vertical cross section. In the first embodiment, the width of the base portion 146a of the annular protrusion 146 (the width along the width direction of the annular thin-walled portion 143) is 0.5 (mm). Further, the predetermined height is a value within the range of 0.1 (mm) to 2.0 (mm).

As a result, in the annular wall portion 140a, when the annular protrusion 146 is pressed toward the annular thin wall portion 143 as described later, the constituent portions of the annular wall portion 140a other than the annular protrusion 146 are not deformed. , It has a shape that can be easily deformed. When the annular wall portion 140a is viewed in the radial direction, the annular projection portion 146 faces the center of the ball portion 145 of each peripheral side engaging piece portion 140b at its top portion 146b.

Here, in the annular body 40 of the metal-resin mixed type adhesive assisting device 100 according to the first embodiment, the grounds for integrally forming the annular protrusion 146 on the annular wall portion 140a will be described.

Conventionally, when burying a mortar adhesive aid in a concrete wall, as described at the beginning of this specification, the mortar adhesive auxiliary tool is in contact with one formwork between both formwork. By sandwiching and pressing one of the molds toward the mortar bonding aid, the mortar bonding aid is clamped between the two molds. Along with this, one of the molds is pressed against the mortar bonding aid.

At this time, when the one mold is made of wood, for example, both sides of the one mold are usually not a uniform flat surface but an uneven surface in many cases. Therefore, for example, when the end face shape of the annular support protrusion that comes into contact with the facing surface of one of the molds of the mortar adhesive auxiliary tool is flat, the end face of the annular support protrusion of the mortar adhesive auxiliary tool and the end face thereof. The facing surfaces of one of the molds do not uniformly contact each other, and a gap is formed between the two.

Further, for example, when the annular support protrusion of the mortar adhesive auxiliary tool has a sharp cross-sectional shape such as a wedge-shaped cross section, the annular end portion of the annular support protrusion has a sharp shape. When the mold is pushed into the mold so as to bite into the facing surface to form an annular groove on the facing surface of one mold, the annular groove of the above-mentioned one mold is formed when the other mold is reused thereafter. Due to this, the mortar bonding auxiliary tool and one mold cannot be uniformly contacted, and a gap due to an annular groove is formed between the contact surface between the mortar bonding auxiliary tool and one mold. It ends up.

In short, the shape of at least one of the annular support projection and the facing surface of the one mold that abuts on the facing surface of one of the mortar adhesion aids is the annular support projection of the mortar adhesion aid and the one mold. If the shape is such that the contact with the facing surface of the concrete cannot be uniformly adhered, the ready-mixed concrete passes between the annular end of the annular support protrusion and the facing surface of one of the formwork and is bonded to the mortar. It leaks into the annular support projection of the auxiliary tool, and the inside of the annular support projection of the mortar bonding auxiliary tool cannot be shielded from the ready-mixed concrete.

Therefore, in the metal-resin mixed type adhesive assisting device 100 referred to in the first embodiment, the annular body 140 is integrally formed with the extending upper end portion of the annular thin-walled portion 143 of the annular wall portion 140a. When one of the molds is pressed against the annular body 140 so as to include the portion 146, the one mold is on the facing surface of the annular thin-walled portion 143 of the annular wall portion 140a. It is pressed toward the extension end.

Here, since the annular protrusion 146 of the annular body 140 is configured to have a shape that is easily deformed as described above, the annular protrusion 146 does not cause deformation of the facing surface of one of the molds. , The annular wall portion 140a can be easily deformed toward the extending end portion of the annular thin wall portion 143.

As a result, one of the molds is pressed toward the extending end of the annular thin portion 143 while deforming the annular protrusion 146 so as to be crushed toward the extending end of the annular thin portion 143. .. As a result, the deformed annular protrusion 146 can be uniformly adhered to the facing surface without forming a gap between the deformed annular protrusion 146 and the facing surface of one of the molds.

The above is the basis for forming the annular protrusion 146 integrally with the annular wall portion 140a of the annular body 140 as described above.

In the first embodiment, the annular protrusion 146 serves as an annular variable portion. On the other hand, the annular wall portion 140a, that is, the annular seating portion 141, the annular thick-walled portion 142, and the annular thin-walled portion 143 cannot be deformed unlike the annular protrusion 146. , It serves as an annular non-variable thick portion and an annular non-variable thin wall portion. The annular non-variable seating portion, the annular non-variable thick portion and the annular non-variable thin-walled portion are also collectively referred to as an annular non-variable wall portion.

Here, in the present embodiment, the functional relationship between the ring member 120 and each of the plurality of engaging pieces 110d and 140b will be described.

The material for forming the ring member 120 is inferior in elongation characteristics to the above-mentioned predetermined light-resistant pigment-containing resin material due to its properties, but is excellent in mechanical strength. Therefore, the ring member 120 functions effectively to suppress cracks in the mortar wall and peeling from the concrete wall at an initial stage such as cracks in the mortar wall and peeling from the concrete wall.

On the other hand, the material for forming the plurality of surface-side engaging pieces 110d of the connector 110 and the plurality of peripheral-side engaging pieces 140b of the annular body 140 is the above-mentioned predetermined light-resistant pigment-containing resin material. Therefore, the plurality of surface-side engaging pieces 110d and the plurality of peripheral engaging pieces 140b of the annular body 140 are inferior in mechanical strength to the forming material of the ring member 120 due to the nature of the forming material. Excellent in elongation characteristics.

For this reason, the plurality of surface-side engaging piece portions 110d and the plurality of peripheral-side engaging piece portions 140b are subject to the mortar under the elongation characteristics after the initial stage such as cracking of the mortar wall or peeling from the concrete wall. It functions to prevent the peeled mortar wall from falling by extending while holding the peeled mortar wall due to cracks in the wall or peeling from the concrete wall.

In short, the ring member 120 exerts a function of suppressing cracks in the mortar wall and peeling from the concrete wall in the initial stage of peeling and the like based on its mechanical strength characteristics, and after the initial stage, the ring member 120 exerts a function of suppressing peeling and the like. The plurality of surface-side engaging pieces 110d and the plurality of peripheral-side engaging pieces 140b exert a function of preventing the peeled mortar wall from falling from the concrete wall based on its extension characteristics.

As described above, in the present embodiment, the ring member 120 and the plurality of surface-side and peripheral-side engaging pieces 110d and 140b synergistically utilize the characteristics of both, and not only the mortar wall is cracked or peeled off. , It also plays a role in preventing the mortar wall from falling from the concrete wall.

The mold tightening bolt 150 is made of a metal material such as stainless steel, and the mold tightening bolt 150 is a separate joint from the outside of the columnar head 110b as shown in any one of FIGS. 1 to 4 and 18. It is coaxially screwed into the female screw hole portion 130a of 130. As shown in either FIG. 4 or FIG. 18, the mold tightening bolt 150 includes a male screw portion 151, a flange portion 152, a tool grip portion 153, and a male screw portion 154. The tool grip portion 153 and the male screw portion 154 are formed coaxially and integrally from the male screw portion 151 to the male screw portion 154 in that order.

Here, the male screw portion 151 is screwed into the female screw hole portion 130a of the separate joint 130 from the annular flange portion 132 side of the separate joint 130. The flange portion 152 is seated on the annular flange portion 132 of the sepa joint 130 in a state where the male screw portion 151 is screwed into the female screw hole portion 130a of the sepa joint 130. The tool grip portion 153 is gripped by a tool (not shown) when the male screw portion 151 is screwed into the female screw hole portion 130a of the separable joint 130. The male screw portion 154 is screwed by a mold tightening nut 170c (see FIG. 19), which will be described later.

In the first embodiment configured as described above, in adhering the mortar wall M (see FIG. 21) to the concrete wall W (see FIG. 19), a plurality of metal resin composite type adhesive assisting devices 100 are used. To. Hereinafter, the metal resin composite type adhesive assisting device 100, which is one of the plurality of metal resin composite type adhesive assisting devices 100, will be described as an example.

First, both concrete formwork Fs (in FIG. 19, only one concrete formwork F is shown) are assembled and installed so as to face each other. Hereinafter, the concrete formwork F is also referred to as a formwork F.

Then, the stainless steel spacer bolt 160 and the metal resin composite type adhesive assisting device 100 prepared in advance are assembled so as to have a constant distance between the two molds F facing each other. Here, the spacer bolt 160 is attached to the sepa bolt 130 of the metal resin composite type adhesive assisting device 100 at the male screw portion in the one side axial direction, and the lower end surface 111 of the truncated cone-shaped body portion 110a of the metal resin composite type adhesive assisting device 100. It is tightened from the side.

After that, the spacer bolt 160 and the metal resin composite type adhesive assisting device 100 screwed in this way are formed in one of the molds F between the two molds F as illustrated in FIG. It is held so as to coaxially correspond to the through hole portion F1 (see FIG. 19).

In the holding state as described above, the formwork tightening bolt 150 as an auxiliary part of the metal resin composite type adhesive assisting device 100 is an annular body of the through hole portion F1 of one formwork F and the metal resin composite type adhesive assisting device 100. Through 140, it is screwed to the sepabolt 130 of the metal-resin composite adhesive auxiliary device 100 (see FIG. 19). This screwing is performed until the flange portion 152 of the form tightening bolt 150 is seated on the annular flange portion 132 of the sepa bolt 130.

Then, as shown in FIG. 19, the formwork tensioning metal fitting 170b, which is a so-called foam tie (registered trademark), is fitted to the male thread portion 154 of the formwork tightening bolt 150 together with the pair of thick end members 170a, and then the mold is formed. The tightening nut 170c is detachably screwed to the male threaded portion 154 of the formwork tightening bolt 150 via a pair of thick end members 170a and a formwork tensioning fitting 170b.

Here, the nut 170c tightens the formwork so as to press one formwork F toward the metal resin composite type adhesive assisting device 100 via the formwork tension fitting 170b and the pair of thick end members 170a. It is screwed and 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 composite type adhesive assisting device 100 and the spacer bolt 160 can be held by both molds F at positions corresponding to the through holes F1 of one mold F. As described above, when one of the molds F is pressed toward the metal resin composite adhesive assisting device 100, the one mold F is formed on the inner surface of the annular body 140 of the metal resin composite adhesive assisting device 100. It is pressed against the annular protrusion 146 at a portion corresponding to the annular protrusion 146.

The pressing force of the nut 170c via one of the molds F on the metal resin composite type adhesive assisting device 100 _{reaches about 200 (kgf / cm 2} ), that is, 19.6 (MPa), but this pressing force is Since it is received by the annular wall portion 140a (annular seating portion 141, annular thick portion 142, and annular thin wall portion 143) of the annular body 140, the ring member 120 is not crushed by the pressing force.

Here, since the annular protrusion 146 is formed so as to be easily deformed as described above, the annular protrusion 146 is formed so as to be crushed by the pressing force of one of the molds F. It deforms toward the extension end.

Along with this, one of the inner surfaces of the one mold F is not deformed at the contact portion with the annular protrusion 146, and the one mold F is formed on the inner surface of the annular thin wall portion of the annular wall portion 140a. It can be uniformly brought into close contact with the annular extending end portion via the deformed annular protrusion 146 (see FIG. 19).

At this time, since one of the molds F is made of wood or a synthetic resin material, the inner surface of the one of the molds F does not have a uniform flat shape, and even if it is curved in an uneven shape, for example. Since the annular protrusion 146 is deformed so as to be crushed as described above, the contact portion with the annular protrusion 146 on the inner surface of one of the molds F is not deformed. This is because the tip of the annular protrusion 146 has a rounded cross-sectional shape, so that the contact portion of the inner surface of one of the molds F with the annular protrusion 146 is further increased. Deformation can be suppressed. This means that the reuse of one mold F can be repeated.

After that, as described above, one of the molds F can uniformly contact the annular protrusion 146 of the annular wall portion 140a on the inner surface thereof, so that between the one mold F and the annular protrusion 146. There is no gap in the formwork.

The pressing force of the nut 170c via one of the molds F on the metal resin composite type adhesive auxiliary device 100 _{reaches about 200 (kgf / cm 2} ), that is, 19.6 (MPa), but this pressing force is , Since it is received by the annular wall portion 140a (annular seating portion 141, annular thick portion 142 and annular thin wall portion 143), the ring member 120, each surface side engaging piece 110d and each peripheral side engaging piece 140b are pushed. It will not be crushed by pressure.

After that, when the ready-mixed concrete is driven between the two formwork Fs, the ready-mixed concrete flows between the two formwork Fs. The ready-mixed concrete means concrete that has not been hardened yet.

At this time, the ring member 120, the plurality of surface-side engaging pieces 110d, and the plurality of peripheral-side engaging pieces 140b of the metal-resin composite adhesive assisting device 100 are the cylindrical head 110b of the connector 110 and the annular wall portion 140a. And because it is sealed in the area surrounded by one formwork F, the ready-mixed concrete leaks into the above area from between the deformed annular protrusion 146 of the annular wall portion 140a and the inner surface of one formwork F. It doesn't get in. As a result, the ring member 120, the plurality of surface-side engaging pieces 110d, and the plurality of peripheral-side engaging pieces 140b can be reliably separated from the ready-mixed concrete.

As described above, when the ready-mixed concrete is driven between the two formwork Fs, the ready-mixed concrete fills the space area between the two formwork Fs except for the metal resin composite type adhesive assisting device 100. Become.

After that, wait for a predetermined waiting time until the ready-mixed concrete filling between the formwork F is hardened. When the ready-mixed concrete is hardened in this way, a concrete wall W (see FIG. 20) is formed. At this time, the concrete wall W is formed with an accommodation hole W1 (see FIGS. 19 and 20) for accommodating the metal resin composite type adhesive assisting device 100.

After the concrete wall W is formed as described above, the nut 170c is screwed off from the formwork tightening bolt 150. Then, 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 separate joint 130 (see FIGS. 19 and 20).

At this time, the formwork tightening bolt 150 is rotated and detached, but the detent portion 110e of the connector 110 engages with the inner peripheral wall portion of the accommodating hole portion W1 in the concrete wall W. It is maintained non-rotatable. Therefore, the metal-resin composite type adhesive assisting device 100 does not rotate together with the rotation of the form tightening 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 accommodating hole portion W1 of the concrete wall W together with the annular seating portion 141 of the annular body 140, so that the metal is formed. Escape of the resin composite type adhesive assisting device 100 from the accommodating hole W1 can be reliably prevented.

Then, both formwork Fs are removed from the concrete wall W. Along with this, as shown in FIG. 20, the concrete wall W is released from both formwork F in a state where the metal resin composite type adhesive assisting device 100 is housed in the housing hole W1. At this time, the metal-resin composite type adhesive assisting device 100 is supported by the separator bolt 130 in the accommodating hole W1 by one axial male screw portion of the spacer bolt 160.

When the metal-resin composite adhesive assisting device 100 is accommodated in the concrete wall W as described above, the raw mortar is applied to the entire surface W2 of the concrete wall W with a predetermined thickness (FIG. 21). reference). The raw mortar means a mortar that has not been cured yet.

At this time, the coating is performed so as to cover the metal resin composite type adhesive assisting device 100 in the accommodating hole W1 of the concrete wall W from the surface W2 of the concrete wall W. Therefore, the metal-resin composite type adhesive assisting device 100 is embedded in the concrete wall W by the raw mortar in a state of being housed in the accommodating hole W1 of the concrete wall W.

With the application of such raw mortar, the raw mortar penetrates into the annular wall portion 140a of the metal resin composite type adhesive assisting device 100. Then, the raw mortar thus infiltrated further passes through the ring member 120, the plurality of peripheral engaging pieces 140b, and the plurality of surface-side engaging pieces 110d, and the extending end surface of the columnar head 110b of the connector 110. Infiltrate towards 113.

Here, as described above, the ring member 120, the plurality of peripheral engaging pieces 140b, and the plurality of surface-side engaging pieces 110d penetrate toward the extending end surface 113 of the columnar head 110b of the connector 110. The raw mortar has a plurality of peripheral engaging pieces 140 and a plurality of peripheral engaging pieces 140 between the ring member 120 and the plurality of peripheral engaging pieces 140b, between the ring member 120 and the plurality of surface side engaging pieces 110d. Between the face-side engaging piece 110d, between the two peripheral engaging pieces of the plurality of peripheral engaging pieces 140b, and between the two connecting pieces 123 and 123 of the plurality of face-side engaging pieces 110d. It passes through the space and reaches the extending end 113 of the columnar head 110b.

Further, the ready-mixed concrete that reaches the extending end portion 113 of the columnar head 110b in this way also reaches the inside of each recess 114 formed in the extending end portion 113 of the columnar head 110b. This means that the ready-mixed concrete also spreads between the surface-side engaging pieces 110d facing each other and the inner surface of the recess 114. Therefore, the amount of raw mortar that penetrates between the plurality of surface-side engaging piece portions 110d and the extending end portion 113 of the columnar head 110b is such that the amount of raw mortar penetrates into the extending end portion 113 of the columnar head 110b is a plurality of recesses. By forming 114, it increases.

After that, the raw mortar applied to the surface W2 of the concrete wall W as described above waits for a predetermined waiting time until it hardens. Along with this, when the raw mortar is hardened, the mortar wall M is formed on the surface W2 of the concrete wall W.

As described above, in the first embodiment, the metal-resin composite type adhesive assisting device 100 is composed of four parts: a connector 110, a ring member 120, a sepa joint 130, and an annular body 140.

Here, the connector 110 having a plurality of surface-side engaging pieces 110d and the annular body 140 having a plurality of peripheral engaging pieces 140b are formed by uniformly containing a light-resistant black pigment in nylon 6. It is formed of a resin material containing a sex pigment.

However, nylon 6 in a predetermined light-resistant pigment-containing resin material has the above-mentioned shear strength, tensile strength, bending strength and flexural modulus. This means that nylon 6 has excellent flexibility even if its mechanical rigidity is low, and at least has good elongation characteristics with respect to an external tensile force.

Therefore, for example, each corresponding portion of the mortar wall with respect to each of the plurality of peripheral engagement pieces 140 (hereinafter, also referred to as a mortar wall portion corresponding to each peripheral engagement piece) is a peripheral engagement of the surface of the concrete wall. When a situation occurs in which the surface portion of the mortar portion corresponding to the mortar (hereinafter, also referred to as the concrete surface portion corresponding to the engaging piece on the peripheral side) is about to peel off, the plurality of engaging pieces 140 on the peripheral side are each an annular wall. Preventing the peeling of the mortar wall portion corresponding to each peripheral engaging piece under a good engagement state with the mortar wall portion corresponding to each peripheral engaging piece with reference to the inner peripheral surface of the portion 140a. As such, it extends in the peeling direction of the mortar wall portion corresponding to each peripheral engagement piece.
Further, each corresponding portion of the mortar wall with respect to each of the plurality of surface-side engaging pieces 110d (hereinafter, also referred to as a mortar wall portion corresponding to each surface-side engaging piece) is the above-mentioned surface-side engaging piece on the surface of the concrete wall. Even if a situation occurs in which each surface portion with respect to the corresponding mortar portion (hereinafter, also referred to as a corresponding concrete surface portion corresponding to each surface side engaging piece) is about to peel off, the plurality of surface side engaging pieces 110d are each circular. Based on the extending end 113 of the columnar head 110b, the mortar wall portion corresponding to each surface side engaging piece is based on a good engagement state with the mortar wall portion corresponding to each surface side engaging piece. The mortar wall portion corresponding to each surface side engaging piece extends in the peeling direction so as to prevent the peeling of the concrete.

As described above, when the mortar wall portion corresponding to each peripheral side engaging piece or the mortar wall portion corresponding to each surface side engaging piece occurs to be peeled off, as described above after the occurrence of this situation. With the extension of each peripheral engagement piece 140 and each surface side engagement piece 110d, the mortar wall portion corresponding to each peripheral engagement piece and the mortar wall portion corresponding to each surface side engagement piece are engaged with each peripheral side. It is possible to prevent peeling from the concrete surface portion corresponding to the mortar and the concrete surface portion corresponding to the engaging piece on each surface side.

On the other hand, the ring member 120 is made of stainless steel SUS304, unlike the formation of the connector 110 and the annular body 140. Therefore, in the metal-resin composite type adhesive assisting device 100, the ring member 120 has stronger rigidity than the resin material such as the above-mentioned light-resistant pigment-containing resin material. The ring member 120 can mechanically exhibit higher strength than the adhesive assisting device x made of only a synthetic resin material.

In other words, the ring member 120 does not have the excellent flexibility of synthetic resins such as nylon 6, but has high rigidity. Therefore, the corresponding portion of the mortar wall with respect to the ring member 120 (hereinafter, also referred to as the ring member compatible mortar wall portion) is the surface portion of the surface of the concrete wall with respect to the ring member compatible mortar portion (hereinafter, also referred to as the ring member compatible concrete surface portion). When a situation occurs in which the ring member 120 is about to peel off, the ring member 120 is subjected to the high rigidity of the ring member 120 from the ring member-compatible concrete surface portion of the ring member-compatible mortar wall portion at the initial stage of the occurrence of the above-mentioned situation. Can be prevented from peeling off.

Here, the outer ring 122 of the ring member 120 is located in the vicinity of each tip portion of the plurality of peripheral engaging piece portions 140b and is surrounded by the respective tip portions. Therefore, the above-mentioned ring member-corresponding mortar wall portion is located in common with or in the vicinity of the above-mentioned peripheral side engaging piece-corresponding mortar wall portion. Along with this, the above-mentioned concrete surface portion corresponding to the ring member is located in common with or in the vicinity of the above-mentioned concrete surface portion corresponding to each peripheral engaging piece.

Therefore, the situation where the above-mentioned mortar wall part corresponding to the ring member and the mortar wall part corresponding to each peripheral engaging piece is about to peel off from the above-mentioned concrete surface part corresponding to the ring member and the concrete surface part corresponding to each peripheral engaging piece is a ring. With the cooperation of the member 120 and the plurality of peripheral engaging pieces 140b, it can be prevented even better.

Further, as illustrated in FIG. 3, the outer ring 122 of the ring member 120 and the plurality of connecting pieces 123 are located in the vicinity of the plurality of surface-side engaging pieces 110d, and the plurality of surface-side engaging pieces are located in the vicinity of the plurality of surface-side engaging pieces 110d. It is located on the side opposite to the extending end portion 113 of the columnar head 110b with respect to the portion 110d. In other words, the outer ring 122 of the ring member 120 and the plurality of connecting pieces 123 are located in the vicinity of the plurality of surface-side engaging piece portions 110d, and have a columnar head via the plurality of surface-side engaging piece portions 110d. The portion 110b is located so as to face the extending end portion 113.

Therefore, the above-mentioned ring member-corresponding mortar wall portion is located in common with or in the vicinity of the above-mentioned surface-side engaging piece-corresponding mortar wall portion. Therefore, the situation where the above-mentioned mortar wall part corresponding to the ring member and the mortar wall part corresponding to each surface side engaging piece is about to peel off from the above-mentioned concrete surface part corresponding to the ring member and the concrete surface part corresponding to each surface side engaging piece is a ring. With the cooperation of the member 120 and the plurality of surface-side engaging pieces 1110d, it can be prevented even better.

The situation where the mortar wall part corresponding to the ring member, the mortar wall part corresponding to each peripheral side engaging piece, and the mortar wall part corresponding to each surface side engaging piece as described above is about to peel off is a ring at the initial stage of the occurrence of the situation. With the cooperation of the member 120, the plurality of peripheral engaging pieces 140b, and the plurality of surface-side engaging pieces 110d, the high mechanical strength characteristics of the ring member 120 and each peripheral engaging piece 140b and each surface-side engaging Based on the excellent elongation characteristics of the light-resistant pigment-containing resin material centered on nylon 6 on one side 110d, it is prevented even better in advance, and after the initial occurrence of the above situation, each peripheral side engagement is performed. With the cooperation of the one-sided portion 140b and each surface-side engaging piece 110d, it can be prevented even better in advance under the excellent elongation characteristics of the light-resistant pigment-containing resin material described above.

Further, in a state where the metal resin composite type adhesive auxiliary device 100 presses the annular wall portion 140a of the annular body 140 into the columnar head 110b of the connector 110 as described above, both of them are formed by the annular protrusion 146 of the annular body 140. A separ joint 130 is connected to a spacer bolt 160 extending from the one formwork side toward the other formwork side so as to face one formwork of the formwork F. Further, the metal-resin composite type adhesive assisting device 100 is pressed toward the connector 110 side through the one mold while deforming the annular protrusion 146 so as to be crushed by the annular wall portion 140a. It should be noted that such pressing force is received by the annular flange portion 110b via the annular wall portion 140a.

As a result, in the metal resin composite type adhesive assisting device 100, the deformation of the annular protrusion 146 described above is the deformation of the annular wall portion 140a (annular seating portion 141, annular thick portion 142 and annular thin wall portion 143) and one of them. By making the formwork F without partial deformation of the facing surface with respect to the annular wall portion 140a, the annular wall portion 140a forms a closed space together with the connector 110 and one of the molds, and the closed space is formed. The ring member 120, the plurality of surface-side engaging pieces 110d, and the plurality of peripheral-side engaging pieces 140b are confined therein.

Therefore, even if the ready-mixed concrete is driven between the formwork F as described above, the plurality of surface-side engaging piece portions 110d, the plurality of peripheral-side engaging piece portions 140b, and the ring member 120 are well separated from the ready-mixed concrete. Therefore, the ready-mixed concrete does not reach the plurality of surface-side engaging pieces 110d, the plurality of peripheral engaging pieces 140b, and the ring member 120. This means that the plurality of surface-side engaging pieces 110d, the plurality of peripheral-side engaging pieces 140b, and the ring member 120 can be in good contact with the raw mortar without being contaminated with ready-mixed concrete.

Further, the portion of the annular body 140 excluding the annular protrusion 146, that is, the annular wall portion 140a (annular seating portion 141, annular thick-walled portion 142, and annular thin-walled portion 143) is formed by one of the molds as described above. Since it is not deformed by pressing, the plurality of surface-side engaging pieces 110d, the plurality of peripheral-side engaging pieces 140b, and the ring member 120 maintain their original shapes well in the above-mentioned closed space. Can be done.

Therefore, as described above, when the raw mortar is applied to the surface W2 of the concrete wall W via the metal resin composite type adhesive assisting device 100, the raw mortar is applied to a plurality of surfaces of the metal resin composite type adhesive assisting device 100. It can satisfactorily engage the side engaging piece 110d, the plurality of peripheral engaging pieces 140b, and the ring member 120. This means that the plurality of surface-side engaging pieces 110d, the plurality of peripheral engaging pieces 140b, and the ring member 120 of the metal-resin composite type adhesive assisting device 100 are formed with the mortar wall M formed after the raw mortar is cured. It means that it can be firmly engaged inside it.

As a result, the metal-resin composite type adhesive assisting device 100 adheres the mortar wall M to the concrete wall W with the plurality of surface-side engaging pieces 110d, the plurality of peripheral engaging pieces 140b, and the ring member 120. It can be satisfactorily assisted and the adhesive force (anchor effect) of the mortar wall M to the concrete wall W can be satisfactorily enhanced.

Further, even after the metal-resin composite type adhesive assisting device 100 is removed by removing both molds F as described above, the metal-resin composite type adhesive assisting device 100 is continuously connected to the spacer bolt 160 by the sepa bolt 130 without being removed. Is maintained at. Here, the ring member 120 is firmly sandwiched between the annular flange portion 132 of the sepabolt 130 and the bottom surface portion 116a of the seating portion 116 of the columnar head 110b by the inner ring 121. As a result, in the metal-resin composite type adhesive assisting device 100, the ring member 120 can be firmly coaxially and mechanically firmly connected to the spacer bolt 160 via the sepa joint 130.

This is due to the high mechanical strength of the metal-resin composite adhesive auxiliary device 100, which is the ring member 120 formed of a steel plate material made of stainless steel, the sepa joint 130 made of stainless steel, and the spacer bolt 160 made of stainless steel. It means that the mortar wall M can be satisfactorily prevented from peeling or falling from the concrete wall W by the coaxial connection for a long period of time.

Here, since the metal-resin composite type adhesive assisting device 100 only protrudes from the surface W2 of the concrete wall W at the plurality of peripheral engaging pieces 140b, the coating thickness of the raw mortar is almost concrete. Not only can it be maintained uniformly over the surface of the wall W, but it can also be made as thin as possible, which helps reduce the amount of raw mortar applied.

As described above, not only one metal-resin composite type adhesive assisting device 100 but also the remaining metal-resin composite type adhesive assisting devices 100 are dispersedly embedded between the concrete wall W and the mortar wall M. Each metal-resin composite type adhesive assisting device 100 enhances the anchoring effect of the mortar wall M on the concrete wall W by the ring member 120, the plurality of surface-side engaging pieces 110d, and the plurality of peripheral-side engaging pieces 140b. obtain.

This means that the mortar wall M does not peel off or fall from the concrete wall W under the strong anchoring effect of the adhesive assistance provided by each metal resin composite type adhesive auxiliary device 100 having the ring member 120 made of a metal material. This means that the adhesion of the concrete wall W to the surface W2 can be well maintained for a long period of time.

Further, in the first embodiment, each metal-resin composite type adhesive assisting device 100 is composed of four separate parts of a connector 110, a ring member 120, a sepa joint 130, and an annular body 140. Here, in the connector 110, since the truncated cone-shaped body portion 110a is formed in a truncated shape so as to be separated from the annular flange portion 110c in the axial direction, the molding die for the connector 110 is a truncated cone-shaped body. A simpler configuration is required as compared with the case where the portion 110a is configured in a divergent shape as the portion 110a is moved away from the annular flange portion 110c in the axial direction. Therefore, the mass productivity of the connector 110 is improved. It should be noted that such a situation can be further improved because the detent portion 110e is projected from the outer peripheral surface portion on the large diameter side of the truncated cone-shaped body portion 110a so as to be along the lower surface of the annular flange portion 110c.

Further, since each metal resin composite type adhesive assisting device 100 has a sepa joint 130 coaxially press-fitted into the connector 110 for connection with the spacer bolt 160, the metal resin composite type adhesive assisting device 100 and the spacer bolt 160 The connection with can be strengthened.

Here, since the ring member 120, the separate joint 130, and the spacer bolt 160 are all formed of stainless steel, the ring member 120, the separate joint 130, and the spacer bolt 160 are mechanically highly rigid and the like. Has strength. Moreover, as described above, the ring member 120 is coaxially connected to the separate joint 130 by being sandwiched by the separate joint 130 with the seating portion 116 of the columnar head 110b, and the spacer bolt 160 is connected to the separate joint 130. It is coaxially attached to the female screw hole portion 140a of the above.

Therefore, each metal-resin composite type adhesive assisting device 100 can be firmly supported by the ring member 120 and the separate joint 130 by the spacer bolt 160 under high mechanical strength. As a result, each metal-resin composite type adhesive assisting device 100 can significantly improve the anchoring effect of the mortar wall M on the concrete wall W.

Further, since each metal-resin composite type adhesive auxiliary device 100 uses the mold tightening bolt 150 as an auxiliary part, it is not necessary to separately prepare the mold tightening bolt, which is convenient. It is convenient to prepare a plurality of mold tightening bolts 150 having different total lengths.

Further, in each metal-resin composite type adhesive auxiliary device 100, the connector 110 and the annular body 140 are formed of a predetermined light-resistant pigment-containing resin material in which nylon 6 uniformly contains the light-resistant black pigment. The connector 110 and the annular body 140 can be maintained in good quality without deterioration for a long period of time even when exposed to external light such as ultraviolet rays.
