Description

  The present invention is a wall material fixing device that re-fixes a wall material that has been floating or peeling off from the wall surface over time, and regardless of the skill level of the operator. The present invention relates to a wall material fixing device capable of reliably performing a fixing operation.

  There are many buildings in Japan and around the world. Buildings such as apartment houses and buildings have wall materials such as tiles and ceramics on their walls. These wall materials are attached to the wall surface as a plurality of wall materials as represented by tiles and the like. For example, these wall materials are fixed to the wall surface with cement or an adhesive.

  However, the plurality of wall materials may become loosened from the wall surface or may be peeled off due to weakening of the wall material or impact due to the passage of time after being fixed. In particular, a large number of wall materials are attached to apartment buildings and buildings, etc., and some or some of the wall materials are likely to float or peel off when exposed to wind and rain or sunlight. Sometimes.

  In this way, leaving a wall material that is floating or peeling off is very dangerous because it leads to the fall of the wall material. For this reason, fixing the floating wall material is performed. There are various methods for this fixing. For example, a hole is made in a floating wall material (the hole is penetrated to the wall surface), and a bolt or the like is inserted into the hole to fix the wall material.

  Various techniques have been proposed for a fixing device and a fixing method for fixing with a bolt or the like after drilling in such a wall material. Among them, for example, a technique has been proposed in which a hole is made in a floating wall material, an adhesive is injected into the hole with a grease gun, and the anchor pin is fixed with the adhesive to fix the wall material. (For example, refer to Patent Document 1 and Patent Document 2).

  The techniques disclosed in Patent Documents 1 and 2 fix a floating wall material by fixing an anchor pin penetrating the wall material using an adhesive as described above.

  Moreover, the technique which fixes the wall material which floats by another method instead of using an adhesive agent is proposed (for example, refer patent document 3, patent document 4, patent document 5, patent document 6).

JP 2006-219970 A JP 2007-120273 A JP 2004-293178 A JP 9-317199 A Japanese Patent No. 3059119 Japanese Patent Laid-Open No. 5-18088

  The techniques disclosed in Patent Document 1 and Patent Document 2 need to inject an adhesive and fix the anchor pin. By fixing with an adhesive, there is an advantage that the fixing force of the anchor pin is increased and the fixing force of the wall material is also increased.

  However, these fixing devices and fixing methods need to work according to the procedures of (1) drilling, (2) injection of adhesive, (3) insertion of bolts and anchors, and (4) fixing. It is very complicated for the person. In particular, in the case of the injection of the adhesive (2), the adhesive may not be evenly distributed in the holes, and the work requires skill, and if it is not a skilled person, the finish may be defective. To do.

  For example, in the injection of the adhesive, bubbles or insufficient injection may occur in the back or in the middle of the hole. When insufficient injection occurs, the fixing force of the anchor and bolt naturally becomes weak. If there is too much adhesive in the hole due to such a lack of injection, the adhesive overflows on the surface of the wall after insertion of anchors and bolts, adversely affecting the finished appearance. .

  In particular, these conventional techniques that require the injection of an adhesive need to handle so-called liquids, can they be injected sufficiently, does not cause dripping, or can the injection be finished before drying Skilled techniques such as are required. Moreover, if these are insufficient, it will also lead to the problem that fixation of wall material will also become inadequate.

  The so-called “wet” fixing of the wall material using a liquid adhesive or the like has a problem that variations in work accuracy occur.

  Moreover, after finishing the work of (1)-(4) with respect to one wall material, and finishing the work of (1)-(4) with respect to another wall material, a perforation machine, the adhesive injection | pouring apparatus, The anchor insertion tool, the anchor fixing tool, and the tool corresponding to the work procedure must be repeatedly replaced. On the other hand, when the work (1), the work (2), the work (3), and the work (4) are performed on each of the plurality of wall materials, the number of tool replacements decreases. However, problems such as drying of the adhesive injected into the holes occur. This is a problem that occurs even when the adhesive injection device disclosed in Patent Document 4 is used (or even if the adhesive injection device disclosed in Patent Document 4 is used, a large amount of adhesive is injected. It is difficult to avoid mistakes such as too much or too little).

  As described above, the fixing device and the fixing method according to the prior art mainly have the problem that the skill of the operator is required mainly for the injection of the adhesive (2).

  On the other hand, there are a large number of housing complexes and buildings in Japan alone, and a considerable number of buildings are causing deterioration over time. For this reason, in many buildings, floating and peeling of wall materials such as tiles are regarded as problems. If left unattended, a serious accident may occur. Nevertheless, there is a shortage of budget and human resources for repairing these floating and peeling wall materials. In such an environment, it is difficult to request repair work from a skilled worker, and there is no time to wait for the worker's skill level to grow.

  That is, even an unskilled worker who can work at low cost can <1> work easily, <2> work with no variation in work results due to work ability, <3 > A large number of wall materials can be repaired in a single operation. <4> There is a need for a fixing device and a fixing method for wall materials with floating and peeling that have no problems in the finished work.

  Similarly to Patent Document 1 and Patent Document 2, Patent Document 3 is wet and requires a resin to fix an anchor pin. For this reason, as in Patent Documents 1 and 2, problems that require the skill level of craftsmen in the injection of adhesives, and the need for skill level, work may be delayed or work results may vary. Have a problem.

  Patent Document 4 discloses a technique for fixing a wall material by inserting a combination of an anchor pin and a washer that are open at the front into a hole drilled in the wall material. A technique for fixing a wall material by expanding the front of an anchor pin in an inserted hole is disclosed. Since Patent Document 4 does not require insertion of a resin or the like unlike Patent Document 1, it has an advantage of not requiring craftsmanship necessary for resin injection.

  However, since only the expansion of the anchor pin is possible, there may be a problem that even if the expansion is performed in the hole, the expansion is insufficient or the pressure application to the surroundings after the expansion is insufficient. In this case, there is a problem that the sufficiently floating wall material cannot be fixed, in addition to the fact that the resin is not cured and fixed.

  Patent Document 5 discloses a technique for fixing a tile or the like from the outside by a combination of an insertion hole inside, a fixing member having a slit in the front, and a core rod inserted into the insertion hole. By inserting the core rod, the front of the fixing member expands and the tile or the like can be fixed. In this respect, it is considered that expansion in the inserted hole is surely facilitated and the wall material can be fixed as compared with Patent Document 4 in which only the anchor pin expands.

  However, since the fixing member and the core rod disclosed in Patent Document 5 merely insert the core rod into the fixing member with a hole, there is almost no fixing force and bonding force between the core rod and the fixing member. . For this reason, even if the fixing member and the core rod are inserted into the insertion hole and the fixing member expands, problems such as the core rod coming out of the fixing member or floating are caused. If it becomes like this, a fixing member cannot fully expand or cannot maintain an expanded state, and fixing force becomes inadequate. Further, since the core rod is simply inserted, there is a problem that due to manufacturing variations of the fixing member and the core rod, sufficient expansion cannot be performed and the floating wall material cannot be fixed.

  In Patent Document 6, unlike other technologies, a wall material is fixed using a complicated structure such as an L-shaped metal fitting. Naturally, the fixing force is high, but there are also problems of causing appearance problems and increasing the labor of the work. This is not a realistic solution.

  Further, in the fixing method according to the conventional technique, since a part of the drilled hole is opened, moisture such as rainwater enters from there and there is a problem that the wall material and the internal structure are corroded.

  An object of the present invention is to solve these problems, and to provide a wall material fixing device that can cope with a simple work that does not require a skill level of work while being low in cost.

In view of the above problems, the wall material fixing device of the present invention is a wall material fixing device for fixing a wall material attached to a wall surface,
A fixing member that is inserted into an insertion hole that reaches the inside of the wall surface from the wall material, and is formed of a deformable material and has an internal space;
An insertion member inserted into the internal space and coupled to the fixing member;
In the internal space of the fixing member, the inner diameter at the front is smaller than the inner diameter at the entrance, or the outer periphery at the front of the fixing member is larger than the outer periphery at the entrance,
By inserting the insertion member into the internal space, the outer periphery of the fixing member expands.

  The wall material fixing device according to the present invention can be fixed by simply inserting a fixing member and an insertion member into the hole. For this reason, there is a merit that the procedure is simple and does not require skill in the work while improving the work speed. In addition, since it is not necessary to inject a liquid material such as an adhesive, there is an advantage that variations in work accuracy are difficult to occur.

  Moreover, since the outer periphery of the hole drilled is closed, the wall material fixing device of the present invention can prevent moisture such as rain water from entering the hole. Due to this prevention, the wall and the internal structure are not easily corroded by moisture.

  As a result, a skilled worker is not required, and a wall material that has a risk of falling off can be fixed to the internal structure with high accuracy while being simple. As a result, the outer wall of the residential building can be repaired.

  (Embodiment 1)

(Overview)
First, the outline | summary of the wall material fixing device in Embodiment 1 is demonstrated.

  FIG. 1 is a schematic diagram of an outer wall of a building according to Embodiment 1 of the present invention. FIG. 1 shows a state in which, for example, outer walls of a housing complex or a building are attached to a wall material that is a plurality of members such as tiles. It is an outer wall often seen in general buildings.

  The outer wall 1 is a general outer wall found on the outside of a building. A large number of wall materials 3 (tiles, ceramics, etc.) are attached to the wall surface 2. In FIG. 1, for ease of viewing, reference numeral “3” is given to one of the plurality of wall materials. Such a plurality of wall materials 3 may include a wall material 4 that is floating or peeling off from the wall surface 2 due to aging or special factors. In FIG. 1, the wall material 4 shown in white is a wall material that is floating or peeling off. In other words, the wall material 4 is a wall material to be repaired. In FIG. 1, a plurality of wall materials are floating or peeling off.

  It is unpredictable where the wall material 4 to be repaired is generated on the outer wall 1, and is generated at random positions. For this reason, in order to detect the wall material 4 to be repaired, it is necessary to inspect all the wall materials 3. Further, as shown in FIG. 1, since the wall material 4 to be repaired is generated at random positions, the repair work (work for fixing the wall material 4) tends to be complicated. Even in such a situation, the work for fixing the wall material 4 is required to have a small number of tool switching and a small number of work switching. Since the wall material fixing device according to the first embodiment can reduce the number of times of tool switching and the number of times of work switching as will be described later, it conforms to the actual situation of the work shown in FIG.

  FIG. 2 is a schematic diagram showing a fixing operation of the wall material fixing device according to Embodiment 1 of the present invention. FIG. 2 shows a state in which the wall material 4 that needs to be fixed explained in FIG. 1 is fixed by the wall material fixing device 10.

  The wall material fixing device 10 fixes the wall material 4 attached to the wall surface 2. The wall material fixing device 10 includes a fixing member 5 and an insertion member 6. The fixing member 5 is inserted into the insertion hole 7 that is penetrated from the wall material 4 into the wall surface 1. The fixing member 5 is made of a deformable material. The fixing member 5 has an internal space 55.

  The insertion member 6 is inserted into the internal space 55 of the fixing member 5 and is coupled to the fixing member. Here, in the internal space 55 of the fixing member 5, the inner diameter at the front (tip side) is smaller than the inner diameter at the entrance, or the outer shape of the outer periphery in front of the fixing member 5 is larger than the outer shape of the outer periphery at the entrance side.

  With such a structure, the outer periphery of the fixing member 5 is expanded by inserting the insertion member 6 into the internal space 55. In particular, since the inner diameter of the front of the fixing member 5 is smaller than the inner diameter of the entrance, when the insertion member 6 is inserted into the internal space 55, the front of the fixing member 5 can be more easily expanded. Due to the large expansion on the front side, the fixing member 5 is more firmly fixed to the inner space 55 in the insertion hole 7 and fixed.

(Change in inner diameter)
As described above, the inner diameter of the internal space 55 of the fixing member 5 is preferably smaller on the front side than on the rear side. Also in FIG. 2, the inner diameter on the front side (wall surface 2 side) of the internal space 55 is smaller than the inner diameter on the rear side.

  Thus, it is preferable that the inner diameter of the internal space 55 of the fixing member 5 changes so as to be smaller on the front side than on the rear side. Of course, the outer diameter may be larger on the front side than on the rear side while the inner diameter is the same.

  Moreover, the inner diameter of the internal space 55 is less than the diameter of the insertion member 6 except for the entrance portion. Thus, when the insertion member 6 is inserted into the internal space 55 of the fixing member 5, the internal space 55 is expanded. In accordance with this expansion, the outer diameter of the fixing member 5 is also expanded. This is because the fixing member 5 is formed of a flexible material.

  In this expansion, since the inner diameter on the front side of the internal space 55 is smaller than the inner diameter on the rear side, the expansion on the front side becomes larger due to the insertion of the insertion member 6. If the expansion on the front side is large, the degree of adhesion of the fixing member 5 to the insertion hole 7 on the front side becomes higher, and the fixing force by the fixing member increases.

  If the fixing force is large, the fixing force to the wall surface 2 of the wall material 4 such as a tile becomes high. In particular, the fixing force at the front side (back side) of the insertion hole 6 is high, so that the fixing force at a place where the wall surface 4 enters deeper increases. As a result, the wall material fixing device 10 can fix the wall material 4 to the wall surface 2 with a strong force.

  Here, the difference in the inner diameter may be a stepwise change (in a staircase shape) or may be a continuous inner diameter change that gradually changes. Any structure that changes (different) the inner diameter may be used.

(Example of inner diameter change)
FIG. 3 is a side view of the wall material fixing device 10 according to the first embodiment of the present invention. FIG. 3 shows the wall material fixing device 10 having a structure in which the inner diameter of the internal space changes stepwise. In addition, FIG. 3 shows a state in which the wall material fixing device 10 is attached to the insertion hole 7 that penetrates the wall surface 2 and the wall material 4.

  This is a case where a wall material 4 is attached to the wall surface 2 and the wall material 4 has a risk of falling off. An insertion hole 7 is provided by drilling a hole from the wall material 4 to the wall surface 2. A wall material fixing device 10 is used in the insertion hole 7.

  As described with reference to FIG. 2, the wall material fixing device 10 of FIG. 3 includes the fixing member 5 and the insertion member 6. In FIG. 3, for convenience of illustration, the insertion member 6 is shown short in relation to the length of the fixing member 5.

  The fixing member 5 has a first region 51, a second region 52, and a third region 53 from the tip (the back side of the wall surface 2). That is, in grasping the structure, the fixing member 5 is divided into a plurality of regions. In FIG. 3, the fixing member 5 is grasped in three areas of the first area 51 to the third area 53, but may be grasped as two areas or four or more areas.

  Here, the inner diameter of the internal space 55 of the fixing member 5 is

    1st area | region 51 <2nd area | region 52 <3rd area | region 53

  Have the relationship. In other words, the inner diameter of the internal space 55 gradually decreases toward the tip side. The inner diameter of the third region 53 corresponding to the entrance of the internal space 55 is the largest (equivalent to the diameter of the insertion member 6 is slightly smaller than that), and the inner diameter is slightly smaller in the second region 52, which is the next region, The inner diameter of the third region 53 on the tip side is further smaller.

  In FIG. 3, the line shown in the inner diameter direction of the second region 52 is longer than the length of the line shown in the inner diameter direction of the first region 51. Similarly, the line shown in the inner diameter direction of the third region 53 is longer than the length of the lines shown in the inner diameter direction of the second region 52 and the first region 51. As can be seen from these relationships, the inner diameter has the relationship of “first region 51 <second region 52 <third region 53” as described above.

  The insertion member 6 is inserted into the internal space 55. The inner diameter of the internal space 55 is less than the diameter of the insertion member 6 in the first region 51 and the second region 52. For this reason, when the insertion member 6 is inserted into the internal space 55 from the entrance (third region 53), first, the internal space 55 of the second region 52 is expanded.

  The fixing member 5 is formed of a flexible and deformable material. For this reason, when the internal space 55 is pushed open, the outer periphery of the fixing member 5 expands. That is, when the insertion member 6 reaches the second region 52, the internal space of the second region 52 is expanded and the corresponding outer periphery is expanded.

  Furthermore, the internal space of the first region 51 is also expanded by inserting the insertion member 6. Since the inner diameter of the first region 51 is smaller than the inner diameter of the second region 52, the first member 51 is pushed and expanded larger than the portion of the second region 52 by the insertion member 6. As a result, the outer periphery of the fixing member 5 expands in the first region 51 than in the second region 52.

  The arrows shown upward and downward of the internal space 55 in FIG. 3 indicate the extending direction of the internal space 55 and the outer periphery.

  Thus, when the insertion member 6 is inserted by having an inner diameter relationship of “first region 51 <second region 52 <third region 53”, the outer periphery of the fixing member 5 becomes “first region 51> It expands in the relationship of “second area 52> third area 53”.

  The expanded fixing member 5 applies pressure to the inner surface of the insertion hole 7. This is because the pressure is applied in close contact. By applying this pressure, the fixing member 5 is fixed to the insertion hole 7. In particular, as described above, by expanding in the relationship of “first region 51> second region 52> third region 53”, the fixing force is also increased by expanding further on the back side of the insertion hole 7.

  At this time, the insertion member 6 inserted into the internal space 55 receives an internal pressure from the fixing member 5 in close contact with the insertion hole 7. The insertion member 6 receives the internal pressure and is fixed to the internal space 55. That is, the insertion member 6 applies pressure to the inner space 55, the fixing member 5, and the inner surface of the insertion hole 7, and the inner surface of the insertion hole 7 corresponds to the fixing member 5, the inner space 55, and the insertion member. Apply pressure to 6.

  Since the bidirectional pressure corresponds, the fixing member 5 is firmly fixed inside the insertion hole 7. The fixing member 5 is suitably formed of resin or vinyl chloride.

  Next, additional elements will be described.

(Insertion member)
The insertion member 6 is preferably at least one of a screw, a screw, and a nail. Of course, these are examples, and things other than these may be used. What is necessary is just to insert in the internal space 55 and to fix inside while expanding the internal space 55.

  In particular, a member that facilitates the operation of inserting the insertion member 6 is suitable so as not to require the skill of the operator. Screws, nails, and the like are preferable in that the work time is short and easy, and skill is not required.

(Projection)
In the first region 51, it is also preferable that the fixing member 5 includes a protrusion 61 on the outer periphery thereof. FIG. 3 shows a state in which the protrusion 61 is provided.

  When the fixing member 5 expands, the protrusion 61 reaches the inside of the insertion hole 7 and can bite into the insertion hole 7. By this biting, the protrusion 61 can fix the fixing member 5 to the insertion hole 7 more strongly.

  FIG. 4 is a side view of the wall material fixing device according to Embodiment 1 of the present invention. 3 shows a state in which the insertion member 6 has been inserted into the internal space 55 from the state of FIG. As shown in FIG. 4, the first treatment 51 of the fixing member 5 expands, and the protrusion 61 bites into the inner surface of the insertion hole 7.

  By having such a state, the fixing member 5 is firmly fixed in the insertion hole 7.

  Here, the protrusion 61 may have various shapes such as a shape with a sharp tip or a shape without a sharp point. Moreover, although various materials may be used, for example, a hard material is more preferable because pressure is applied to the inner surface of the insertion hole 7.

  As described above, the fixing force of the fixing member 5 is further increased by providing the protrusion 61 in the first region 51 that is required to have a high fixing force.

  It is also preferable that the fixing member 5 has one or a plurality of slits on the side surface.

  It is because the fixing member 5 is expanded by the slit when the insertion member 6 is inserted into the fixing member 5 and joined by having the slit. By this expansion, the fixing member 5 expands and applies pressure to the inner periphery of the insertion hole 7.

  In the case of the slit, it can be easily expanded even if the material of the fixing member 5 is hard. In addition, it becomes easy to maintain the expanded form. The fixed member 5 can maintain a strong fixing force inside the insertion hole 7 by this expanded form.

    (Peripheral material)

  In at least a part of the second region 52 and the third region 53, the fixing member 5 is preferably provided with an outer peripheral member 62 on the outer periphery thereof. FIG. 3 shows the outer peripheral material 62. In FIG. 3, the outer peripheral material 62 is provided in the second region 52. It is only necessary that the outer peripheral material 62 is provided in a part other than the place where the protrusion 61 is provided.

  The outer peripheral member 62 can be in close contact with the inner periphery of the insertion hole 7 when the fixing member 5 expands. FIG. 5 shows a state in which the outer peripheral member 61 is in close contact with the inner periphery of the insertion hole 7. FIG. 5 is a side view of the wall material fixing device after fixing in the first embodiment of the present invention.

  As shown in FIG. 4, after the insertion member 6 is inserted into the internal space 55, the fixing member 5 expands. In this expansion, when the outer peripheral member 62 shown in FIG. 3 is provided, the outer peripheral member 62 comes into close contact with the inner periphery of the insertion hole 7.

  In FIG. 5, it seems that the outer peripheral material 62 is provided only on the upper and lower sides of the fixing member 5, but actually, the fixing member 5 is provided so as to go around the outer periphery. For this reason, in the insertion hole 7, the outer peripheral material 62 fills the entire gap between the fixing member 5 and the insertion hole 7.

  Since the outer peripheral member 62 is in close contact with the inner periphery of the insertion hole 7, a gap that may be generated between the fixing member 5 and the insertion hole 7 is filled. As a result, the closely attached outer peripheral material 62 can prevent moisture from entering the back of the insertion hole 7. The wall 2 is present behind the insertion hole 7 and is a structure.

  The insertion hole 7 is formed from the wall material 4 and moisture may enter from this entrance. In the middle of the insertion hole 7, the outer peripheral material 62 closely adheres to prevent a gap, so that it is possible to prevent moisture from entering. The wall surface 2 is a structural body, and intrusion of moisture is not preferable from the viewpoint of durability. The merit which can prevent this is high.

(lid)
FIG. 6 is a side view of the wall material fixing device according to Embodiment 1 of the present invention. In FIG. 6, a lid 8 for closing the entrance of the insertion hole 7 is further provided. The lid 8 is attached after the insertion member 6 is inserted into the internal space 55.

  The lid 8 is also effective in maintaining aesthetics so that the insertion hole 7 and the insertion member 6 are not visible on the surface. In addition, it is possible to prevent rainwater and the like from entering the insertion hole 7. In particular, the lid 8 can reliably prevent moisture from entering the insertion hole 7 together with the outer peripheral member 62 that is in close contact with the inner periphery of the insertion hole 7.

  Thus, it is also preferable that the lid 8 is provided.

(Penetration of insertion member)
It is also preferable that the insertion member 6 has a sharp tip, and when the insertion member 6 is inserted into the internal space 55, the tip penetrates from the tip of the fixing member 5 and is fixed to the wall surface 2.

  FIG. 7 is a side view of the wall material fixing device fixed to the wall surface in the first embodiment of the present invention. In FIG. 7, the distal end of the insertion member 7 penetrates the distal end of the fixing member 5 and is stuck in the wall surface 2 as it is.

  By being in this state, the insertion member 6 is fixed to the wall surface 2. By being fixed, it becomes difficult for the insertion member 6 to come out of the fixing member 5, and the possibility that the fixing is loosened after the wall material 4 is fixed is extremely reduced.

  As described above, it is also preferable that the insertion member 6 is fixed to the wall surface 2.

  As described above, the wall material fixing device 10 according to the first embodiment can fix the wall material 4 attached to the wall surface 2 and possibly peeled off by a simple operation. At this time, since the work is simple, no skill is required, and there is a merit that the fixed maintenance ability after the work is high.

(Insertion hole)
The insertion hole 7 is a hole that reaches the inside of the wall surface 2 from the outside of the wall material 4. At this time, the length from the surface of the wall surface 2 to the front of the insertion hole 7 may be determined as appropriate. However, in order to increase the fixing force by the pair of the fixing member 5 and the insertion member 6, the length from the surface of the wall surface 2 to the front is preferably longer than the thickness of the wall material 4. This is because the amount of insertion of the fixing member 5 inside the insertion hole 7 is naturally improved when the amount of insertion inside the wall surface 2 is larger than the amount of insertion of the wall material 4.

  Further, it is appropriate that the insertion hole 7 has substantially the same inner diameter at the entrance and the front. This is because having substantially the same inner diameter facilitates the insertion of the fixing member 5 and facilitates the fixing by the front expansion of the fixing member 5.

  (Embodiment 2)

Next, a second embodiment will be described.
The wall material fixing device 10 of the second embodiment performs fixing in combination with the adhesive inserted into the insertion hole 7.

  FIG. 8 is a side view of the wall material fixing device according to Embodiment 2 of the present invention. The elements described with reference to FIG. 2 are omitted for convenience of illustration.

  An adhesive capsule 9 is inserted in the insertion hole 7 in advance. In FIG. 8, the adhesive capsule 9 is inserted in the back of the insertion hole 7 (the wall surface 2 side). After the adhesive capsule 9 is inserted, the fixing member 5 is inserted. Thereafter, the insertion member 6 is inserted into the internal space 55.

  The fixing by the expansion of the fixing member 5 by the insertion member 6 being inserted into the internal space 55 of the fixing member 5 is as described in the first embodiment.

  In FIG. 8, the insertion member 6 further penetrates the internal space 55 of the fixing member 5. The inserted insertion member 6 ruptures the adhesive capsule 9. Due to this rupture, the adhesive contained in the adhesive capsule 9 overflows into the insertion hole 7. The overflowing adhesive, together with the fixing member 5 and the insertion member 6, can fix the elements inside the insertion hole 7 to the inner periphery of the insertion hole 7.

  Through these fixings, the wall material 4 can be fixed more strongly.

  The insertion member 6 penetrates the internal space 55 of the fixing member 5 and crushes the adhesive capsule 9 installed at the tip thereof, so that the wall material is fixed by the interaction between the expanding fixing member 5 and the adhesive. The fixing force of the device 10 is further increased.

  The adhesive capsule 9 only needs to contain various adhesives. For example, it contains a resin curing agent, and is cured only when the adhesive capsule 9 is crushed. By such an action, the adhesive fixing effect is exhibited by the insertion of the insertion member 6.

  Next, a wall material fixing method using the wall material fixing device 10 will be described.

(Wall material fixing method)
A wall material fixing method using the wall material fixing device shown in FIG. 2 and the like will be described step by step.

  FIG. 9 is a flowchart showing the procedure of the wall material fixing method according to the second embodiment of the present invention. First, in step ST1, an insertion hole 74 reaching the inside of the wall surface 2 is drilled from the wall material 4 that is about to float or peel off. Step ST1 is a drilling process.

  Next, the fixing member 5 is inserted into the insertion hole 7 in step ST2. Step ST2 is a fixing member insertion step. When the fixing member 5 is inserted into the insertion hole 7, the fixing member 5 has the internal space 7, and the insertion member 6 is inserted into the internal space 7 in step ST3. At this time, the insertion member 6 is coupled to the fixing member 5. That is, step ST3 is a coupling process.

  The work is completed in these three steps. When the three steps as work are completed, an effect is produced. That is, in step ST <b> 4, the front of the fixing member 5 is expanded, pressure is applied to the insertion hole 7, and the fixing member 5 is fixed inside the insertion hole 7. Next, the wall material 4 is fixed to the wall surface 2 in step ST5.

  With the above procedure, the wall material fixing method can fix the wall material 4 that is floating or peeling off to the wall surface 2. In particular, since the injection of resin or adhesive is not required, the skill level of the operator is not required, and variations in work finish can be prevented.

  Further, at this time, as shown in FIG. 8, it is also preferable that the adhesive capsule 9 is previously installed in the insertion hole 7.

  As described above, the wall material fixing device 10 according to the second embodiment has a stronger fixing effect.

  In addition, the wall material fixing device described in the first and second embodiments is an example for explaining the gist of the present invention, and includes modifications and modifications without departing from the gist of the present invention.
