Description

Adhesive aid for mortar and adhesive aid system for mortar

The present invention relates to a bonding aid for mortar suitable for bonding a mortar to a concrete structure, and a bonding aid for a mortar provided with the bonding aid.

Conventionally, in the construction of a concrete structure, a plurality of spacer bolts are used to maintain two templates facing each other at a predetermined interval. In this state, the ready-mixed concrete is poured between the two stencils to be solidified, and then the two stencils are removed, thereby constructing the concrete structure.

Moreover, the concrete structure constructed in this manner is in a state in which only the formwork is removed, and thus the appearance of the surface of the concrete structure is not good. Therefore, in order to improve the appearance, the mortar wall is usually formed by coating and solidifying the surface of the concrete structure by the mortar.

Here, the wall of the mortar formed as described above changes with the passage of time. Along with this, if the mortar wall is deteriorated with respect to the surface of the concrete structure and with the passage of time, the mortar wall is easily peeled off from the surface of the concrete structure.

In response to this, a mortar bonding aid described in Japanese Laid-Open Patent Publication No. 2000-45480 is proposed. The mortar bonding aid is integrally formed by a truncated cone-shaped plug portion and a plurality of loop-shaped locking portions formed on the plug portion.

When the mortar is applied to the frame concrete by using the mortar bonding aid thus formed, the adhesive is applied to the outer peripheral surface or the bottom surface of the embedding portion. Then, the embedding portion is embedded in a cone trace formed on the surface of the frame concrete as will be described later. At this time, the embedding is performed such that the locking portion is exposed from the surface of the frame concrete.

Here, the tapered trace is formed on the frame concrete in the following manner. That is, a joint having an outer shape corresponding to the taper mark is provided in the two sheets, and then the ready-mixed concrete is poured into the two sheets through the joint and solidified, thereby forming the frame concrete. Next, when the stencil is removed together with the connecting member from the frame concrete, the frame concrete is formed in a manner having a tapered mark having a shape corresponding to the connecting member.

As described above, after the mortar bonding aid is embedded in the tapered trace of the frame concrete, the ready-mix mortar is applied to the surfaces of both the mortar bonding aid and the frame concrete.

At the stage of coating the ready-mixed mortar as described above, the ready-mixed mortar is in an uncured state, and thus it is immersed in the locking portion of the mortar bonding aid. Thus, when the ready-mixed mortar is solidified in this state, the mortar-adhesive aid can exert a high anchor effect with respect to the cured mortar. This means that the mortar can be prevented from peeling off from the frame concrete.

[Problem to be Solved by the Invention] However, in order to utilize the mortar bonding aid constructed in the above manner when the mortar is coated with respect to the frame concrete, it is necessary to detach the connector for the formwork from the frame concrete of the form as described above. This extra work.

Further, after the connector is removed as described above, it is also troublesome to change the operation of attaching the mortar bonding aid to the tapered mark.

Moreover, the connector that is detached as described above will be discarded after being used several times. Therefore, there is a problem that the connection member acts as a waste to cause environmental pollution.

Here, an example in which the mortar wall M is adhered to the concrete wall 10a of the plurality of concrete walls based on the adhesion assist of the adhesion assisting system MS in the structure shown in FIG. 1 will be described.

First, in the template setting step S1 of Fig. 14, the two concrete formwork sheets F (only one of the concrete form sheets F shown in Fig. 15) are assembled and arranged to face each other. In addition, hereinafter, the concrete form F is also referred to as a form F.

Then, in the spacer bolt and the first bonding assisting device assembly step S2, the plurality of spacer bolts 150, the plurality of template fastening bolts 160, and the plurality of first bonding assisting devices 100 (the pre-embedded bonding aid 100) are prepared in advance. The four spacer bolts 150, the four template fastening bolts 160, and the four first bonding aids 100 are assembled between the two templates F.

Here, the four spacer bolts 150, the four template fastening bolts 160, and the four first bonding assisting devices 100 are arranged such that the intervals thereof are fixed at intervals with respect to the two templates F facing each other as described below. Be assembled.

For example, the upper left side bonding assisting device 100 of the four first bonding assisting devices 100 is an example in which the corresponding spacing bolt 150 for the upper left side bonding assisting device 100 of the four spacing bolts 150 is axially The threaded portion is fixed to the back side female screw hole portion 111b of the connector 110 of the upper left side bonding assisting device 100.

Then, the corresponding spacing bolts 150 and the upper left side bonding assisting device 100 thus screwed together, as exemplified in FIG. 15, between the two templates F and the through hole portion F1 formed in one of the templates F (refer to the figure) 15) Hold in a coaxially corresponding manner.

In the next template fastening bolt fixing step S3, in the holding state as described above, the corresponding template fastening bolt 160 for the upper left side bonding assisting tool 100 among the four template fastening bolts 160 is passed through a so-called Form Tie (registered trademark), that is, a template tensioning member 160a and a pair of beads 160b, are inserted into the through hole portion F1 of one of the templates F, and pass through the annular support wall 140 of the upper left side bonding assisting device 100. The annular connecting wall 130 is detachably screwed to the surface side female screw hole portion 111a of the female screw hole portion 111 of the connector 110. In addition, the corresponding spacer bolt 150 is fixed to the other template F with the other side axial male thread portion.

Thereby, the left upper side bonding assisting device 100 and the corresponding spacing bolt 150 can be held by the corresponding template fastening bolts 160 at the two templates F at positions corresponding to the through hole portions F1 of one of the templates F. Further, the portion where the through hole portion F1 of the template F is formed corresponds to the upper left corner portion of the first rectangular shape outline RL (see FIG. 1) in the concrete wall 10a.

In this state, the nut 160c is detachably screwed to the corresponding template fastening bolt 160 from the outer end side thereof. Here, the nut 160c is screw-adjusted with the corresponding template fastening bolt 160 via the template tensioning member 160a and the pair of beads 160b to face the surface of the connector 110 in a screwed state with the corresponding spacing bolt 150. Press one of the templates F to the side.

Along with this, the annular support wall 140 is pressed toward the annular flange 115 of the connector 110. Then, since the annular connecting wall 130 is formed to be easily deformed as described above, the annular supporting wall 140 is displaced to the receiving surface of the annular flange 115 while being bent and deformed. Until 115a. At this time, the annular connecting wall 130 is bent and deformed while being reversed, and is interposed between the inner circumferential surface of the annular supporting wall 140 and the outer circumferential surface of the small diameter portion 110b of the connector 110.

Further, when the annular support wall 140 abuts against the receiving surface 115a of the annular flange 115 with the lower end portion thereof, the annular connecting wall 130 is on the inner circumferential surface of the annular supporting wall 140 and the small diameter portion 110b of the connecting member 110. The outer peripheral surface is deformed into a wedge shape to maintain the annular support wall 140 in a fixed state with respect to the connector 110.

Then, the annular support wall 140 is supported by the receiving surface 115a of the annular flange 115 in a state in which the annular connecting wall 130 is bent and deformed on the inner peripheral surface side thereof (see FIG. 15). Therefore, the annular connecting wall 130 and the plurality of face-side engaging pieces 120 are surrounded by the annular supporting wall 140 so as to be sealed between the small-diameter portion 110b of the connecting member 110 and one of the templates F.

Further, the pressing force of the nut 160c on the first bonding assisting device 100 via one of the templates F reaches about 200 (kgf/cm ² ), that is, 19.6 (MPa), but the pressing force is blocked by the annular supporting wall 140, so Each of the face side engaging pieces 120 is not crushed by the pressing force.

After the treatment of the form fastening bolt fixing step S3, in the ready mixed concrete pouring step S4, the ready mixed concrete is poured between the two form plates F. Along with this, the ready-mixed concrete flows between the two forms F. In addition, the term "premixed concrete" refers to concrete that has not been cured.

At this time, the upper left side bonding assisting device 100 is sealed as described above, and the annular connecting wall 130 and the plurality of face side engaging pieces 120 are sealed between the small diameter portion 110b of the connecting member 110 and one of the templates F, so that the ready-mixed concrete is It does not enter the inside of the annular support wall 140. Thereby, the plurality of face-side engaging pieces 120 can be reliably separated from the ready-mixed concrete.

As described above, the premixed concrete flows into the two formwork F, and the ready-mixed concrete will fill the area other than the upper left side bonding aid 100 in the space area between the two formwork.

Then, in the next ready-mixed concrete curing waiting step S5, the predetermined waiting time is waited until the ready-mixed concrete between the two formwork F is solidified. Thus, when the ready-mixed concrete is solidified, the concrete wall 10a is formed. At this time, the receiving hole portion 12 in which the left upper side bonding assisting device 100 is housed is formed in the concrete wall 10a.

In the next form fastening bolt removal step S6, the nut 160c is detached from the corresponding form fastening bolt 160. Then, the template tensioning member 160a and the pair of beads 160b are detached from the corresponding template fastening bolts 160, and the corresponding template fastening bolts 160 are detached from the surface side female screw hole portions 111a of the coupling member 110.

At this time, the corresponding template fastening bolts 160 are rotated to be disengaged, but the ribs 116a formed on the outer circumferential surface of the connector 110 are maintained in a non-rotatable manner by the peripheral wall portion of the accommodation hole portion 12 of the concrete wall 10a, and therefore the first bonding aid is provided. 100 does not accompany the rotation of the corresponding form fastening bolt 160 to co-rotate. Further, since the annular flange 115 of the connecting member 110 is held in the peripheral wall portion of the receiving hole portion 12 in the concrete wall 10a, the first bonding assisting device 100 does not fall off from the receiving hole portion 12.

The processing of the above-described steps is also performed in the same manner for each of the remaining first bonding assisting devices 100 in the four first bonding assisting devices 100 of Fig. 1 .

Next, in the formwork removing step S7, the two form plates F are detached from the concrete wall 10a. As a result, the concrete wall 10a is liberated from the two templates F in a state in which the left upper side bonding assisting device 100 is housed in the receiving hole portion 12 as shown in FIG. At this time, the left upper side bonding assisting device 100 is supported by the one side axial male screw portion of the spacer bolt 150 projecting from the bottom wall portion thereof in the receiving hole portion 12 by the back side female screw hole portion 111b of the connector 110.

Then, in the second bonding assisting device assembly step S8, the center side bonding assisting device 200 of the plurality of second bonding assisting devices 200 is assembled to one of the templates F as described below.

In other words, the center-side bonding assisting device 200 is provided on the substrate 210 at a corresponding portion facing the center of the first rectangular-shaped contour RL on the surface 11 of the concrete wall 10a (see FIGS. 1 and 17). At this time, as shown in FIG. 17, the substrate 210 is provided on the back surface of the concrete wall 10a so that the plurality of surface side engagement pieces 230 and the four hook portions 220a to 220d protrude outward.

In the above-described arrangement, the spacer WS shown in FIG. 18 is provided on the annular portion of the substrate 210 centering on the central hole portion 211 via the four hook portions 220a to 220d as shown in FIG. It is called the central annular part P).

Here, the spacer WS is provided on the central annular portion P such that the hook portions 220a to 220d are expanded by the bending portion 222 against the elastic force thereof. Therefore, the spacer WS is sandwiched between the bent portion 222 of each of the hook portions 220a to 220d and the annular central portion P of the substrate 210 inside the respective hook portions 220a to 220d.

In the first embodiment, the gasket WS is a flat gasket, for example, formed of a stainless steel ring shape, and the thickness Z, the inner diameter Ri, and the outer diameter Ro of the gasket WS are respectively set to Z = 0.7 (mm), Ri = 6 (mm) and Ro = 13 (mm). In addition, the central annular portion P is an annular region formed on the substrate 210 from the inner side (the center hole portion 211 side) of the extending bottom portion of the substrate 210 in the vertical portion 221 of each of the hook portions 220a to 220d.

After the spacer WS is held in the above manner, the concrete screw SC is fixed to the concrete wall 10a with the column portion passing through the hollow portion of the spacer WS and the central hole portion 211 of the substrate 210 as shown in FIG.

This fixing is performed by an electric tool (not shown), after passing through the hollow portion of the spacer WS and the central hole portion 211 of the substrate 210 on the concrete wall 10a to form the lower hole portion. The concrete screw SC is fixed to the lower hole portion with the column portion passing through the hollow portion of the spacer WS and the central hole portion 211 of the substrate 210.

In this fixed state, since the inner diameter Ri of the spacer WS is the same as the inner diameter V of the central hole portion 211 of the substrate 210, the concrete screw SC can firmly hold the spacer WS on the substrate 210 with its head. The outer peripheral portion of the central hole portion 211. Therefore, the substrate 210 can be firmly assembled to the concrete wall 10a in a stable state by the spacer WS and the concrete screw SC.

As described above, when the assembly of the four first bonding assisting devices 100 and the second bonding assisting device 200 (the center side bonding assisting device 200) with respect to the concrete wall 10a is completed, in the next ready-mix mortar applying step S9, The ready-mixed mortar is applied to the entire surface 11 of the concrete wall 10a with a predetermined thickness as shown in Figs. 2 and 3. In addition, the so-called ready-mixed mortar refers to a mortar that has not yet been cured.

At this time, the coating is performed so as to cover the four first bonding assisting devices 100 and the second bonding assisting device 200 on the surface of the concrete wall 10a. Therefore, in the state in which the first bonding assisting device 100 is housed in the receiving hole portion 12 of the concrete wall 10a, the ready-mixed mortar is embedded in the concrete wall 10a, and the second bonding assisting device 200 is on the concrete wall 10a. The surface 11 is buried by the premixed mortar.

Along with this, the ready-mixed mortar is immersed in the inside of the annular support wall 140 of each of the first bonding aids 100. Then, the ready-mixed mortar thus immersed is further immersed toward the surface of the connecting member 110 via the plurality of face-side engaging pieces 120, and immersed in the inside of the annular groove portion 112 and the surface-side female screw hole portion of the female screw hole portion 111. The interior of 111a.

Here, the ready-mixed mortar impregnated toward the surface of the connector 110 via the plurality of face-side engaging pieces 120 as described above passes through the respective faces of the plurality of face-side engaging pieces 120 to reach the surface of the connecting member 110.

Moreover, the ready-mixed concrete which reaches the surface of the connecting member 110 in this way also reaches the respective curved surface portions 114 formed on the surface of the connecting member 110. This means that the ready-mixed concrete also passes between the face-side engaging pieces 120 and the curved surface portion 114 facing each other. Thus, the amount of the ready-mixed mortar immersed between the plurality of face-side engaging pieces 120 and the surface of the connecting member 110 is increased by forming a plurality of curved surface portions 114 on the surface of the connecting member 110.

Further, the ready-mixed mortar immersed in the annular support wall 140 as described above is also immersed in the inside of the annular groove portion 112 and the inside of the surface-side female screw hole portion 111a of the female screw hole portion 111.

Further, in the second bonding assisting device 200, when the ready-mixed mortar is applied as described above, the ready-mixed mortar reaches the surface of the substrate 210 via the plurality of surface-side engaging pieces 230. Here, the ready-mixed mortar that has reached the surface of the substrate 210 via the plurality of surface-side engaging pieces 230 passes through the plurality of outer side opening portions 213a to 270a of the substrate 210 between the adjacent two-side-side engaging pieces 230. The interior of 213j.

After the ready-mix mortar application step S9 as described above, in the next ready-mix mortar solidification waiting step S10, the predetermined time is waited until the ready-mixed mortar applied to the surface 11 of the concrete wall 10a is solidified as described above. . Along with this, when the ready-mixed mortar is solidified, a mortar wall M is formed on the surface 11 of the concrete wall 10a.

As described above, in the first embodiment, the adhesion assisting system includes the plurality of first bonding assisting devices 100 and the plurality of second bonding assisting devices 200 configured as described above. Here, the plurality of first bonding assisting devices 100 are coupled to the plurality of spacer bolts 150 extending from the one template side toward the other template side such that the annular supporting walls 140 face one of the two templates F. . Further, the plurality of first bonding assisting devices 100 are deformed by the respective annular supporting walls 140, and are pressed toward the respective connecting members 110 via the one of the templates. In the meantime, the plurality of first bonding assisting devices 100 are seated in a ring shape extending in the radial direction from the outer peripheral portion of the surface of the corresponding connector 110 toward the outside so as to surround the plurality of surface-side engaging pieces 120. Flange 115.

Therefore, in each of the plurality of first bonding assisting devices 100, the annular supporting wall 140 forms a sealed space together with the annular flange 115 and one of the templates, and the plurality of surface-side engaging pieces 120 are enclosed in the sealed space. Therefore, even if the ready-mixed concrete is poured between the two formwork F as described above, the plurality of face-side engaging pieces 120 are isolated from the ready-mixed concrete. Therefore, the ready-mixed concrete does not reach the plurality of face-side engaging pieces 120.

Further, since the annular support wall 140 is different from the annular connecting wall 130 and is not deformed by the pressing of one of the stencils, the plurality of face-side engaging pieces 120 can maintain their original shape well in the sealed space.

Therefore, as described above, by applying the ready-mixed mortar to the surface 11 of the concrete wall 10a via the plurality of first bonding aids 100, the ready-mixed mortar can be favorably engaged with each of the first bonding aids 100. The face side engaging piece 120. This means that the plurality of face-side engaging pieces 120 of the respective first bonding aids 100 can be firmly engaged in the mortar wall M formed after the ready-mixed mortar is solidified.

Here, in each of the first bonding assisting devices 100, the plurality of face-side engaging pieces 120 or the left and right upper side engaging piece groups 120a and 120b are respectively on the surface of the substrate 110 with respect to the center line of the left-right direction and up and down. Since the direction center line is symmetrically disposed, the adhesion assisting force with respect to the mortar wall M by the respective face side engaging pieces 120 or the respective side engaging piece groups 120a and 120b can extend over the entire surface of the connecting member 110. It is produced evenly.

As a result, the plurality of first bonding assisting devices 100 can favorably assist the bonding of the mortar wall M with respect to the concrete wall 10a by using the plurality of surface-side engaging pieces 120, so that the mortar wall M can be favorably improved with respect to the concrete wall. 10a adhesion (anchor effect).

Further, after the plurality of first bonding members 100 are detached and removed as described above, the plurality of first bonding assisting devices 100 are connected to the corresponding spacer bolts 150 by the respective connecting members 110 without being detached, and can be continuously maintained. Therefore, it is not necessary to repeat the detaching work or the new mounting work of the plurality of first bonding assisting devices 100. Therefore, it is possible to improve the workability and prevent environmental pollution caused by the disposal of the plurality of first bonding assisting devices 100. Produced in the first place.

Further, as described above, the concrete wall 10a is formed by solidification of the ready-mixed concrete between the two formwork F, and after the two formwork F is removed, the plurality of second bonding aids 200 are dispersed on the surface 11 of the concrete wall 10a. It is disposed at a position different from the plurality of first bonding assisting devices 100 (the central portion of the rectangular shape outline RL), and is fixed to the surface 11 of the concrete wall 10a by the respective screws SC in the central hole portion 211.

Therefore, the plurality of second bonding assisting devices 200 are firmly assembled to the surface of the concrete wall 10a by the respective screws SC. In this state, by applying the ready-mixed mortar to the surface 11 of the concrete wall 10a as described above, the ready-mixed mortar can be similar to the plurality of surface-side engaging pieces of the plurality of first bonding assisting devices 100. The plurality of face-side engaging pieces 230 of each of the plurality of second bonding assisting devices 200 are firmly engaged.

With this, the ready-mixed mortar is solidified to form a mortar wall, whereby the plurality of surface-side engaging pieces 230 of each of the plurality of second bonding assisting devices 200 can be internally provided with each of the plurality of first bonding assisting devices 100. Similarly, the plurality of face-side engaging pieces 120 are firmly engaged with the mortar wall.

Here, in each of the second bonding assisting devices 200, the plurality of face-side engaging pieces 230 or the left and right upper side engaging piece groups 230a and 230b are respectively on the surface of the substrate 210 with respect to the left-right direction center line X and the vertical direction. Since the center line Y is symmetrically disposed, the adhesion assisting force with respect to the mortar wall M by the respective face side engaging pieces 230 or the right and left side engaging piece groups 230a and 230b can be spread over the substrate 210. Produced evenly over the entire surface.
