Description

The present invention relates to a method for installing panel materials for architectural walls, and more specifically, to a method for installing panel materials and base materials using an adhesive without using welding.

The curtain walls (non-structural walls) used for partition walls and exterior walls of buildings are mainly made of so-called secondary product panels (plate-shaped wall materials) produced in factories. Among them, ALC (Autoclaved Lightweight aerated Concrete) panels are one of the most preferred secondary product panels because they have excellent fire resistance, heat insulation, and sound insulation properties, and above all, are lightweight.

Nearly 50 years have passed since ALC panels were introduced in Japan, and because they have been adopted in large numbers during this time, "ALC structural design standards" have been developed, and standard construction methods for ALC installation have also been established. There is. Several construction methods are stipulated in this standard construction method for ALC installation. For example, one of them, the rocking construction method, follows the in-plane direction when deformation occurs in a building due to an earthquake. This is a construction method in which the ALC panel is installed so that it rotates slightly (for example, 1/100 rad).

Normally, secondary product panels such as ALC panels (hereinafter simply referred to as "panel materials") are installed using steel sections (generally angle iron) called "mounting bases." Ru. More specifically, after fixing the mounting base to the steel beams and columns (generally H-beams and I-beams) that make up the structural frame by on-site welding, and placing the panel materials in designated positions, The mounting hardware anchored to the panel material and the mounting base are fixed by on-site welding.

Even with the standard construction method for ALC installation explained earlier, when installing an ALC panel, the mounting base is still fixed to the structural frame (beam or column) by on-site welding, and the ALC panel mounting hardware is fixed by welding or bolts. It is specified that it must be fixed to the mounting base.

In this way, on-site welding has been a prerequisite for installing panel materials, and although improvement techniques focusing on details such as installation jigs have been proposed, other joining methods to replace welding have not yet been proposed. It was never proposed. For example, Patent Document 1 proposes a mounting bracket that has a higher strength than conventional ones and will not destroy the panel even if external force is applied, but this mounting bracket is also welded to the L-shaped angle (mounting base). It will be fixed.

Welding is a method of joining two parts by melting the two steel materials (base metals) to be joined together, or by melting and adding a steel material of the same quality (filler metal). There are various types of welding, such as welding, electron beam welding, and laser welding, but arc welding is the most commonly used. Arc welding is a method in which a potential difference is applied between slightly separated electrodes to generate an arc, and the heat generated by the arc of air discharge melts the base metal and filler metal. Specifically, a welding rod (filler metal) connected to one end of the electrode is brought close to the base metal connected to one end of the electrode to generate an incandescent arc (arc light), and the heat of the arc damages the base metal. As it melts, the molten steel from which the steel of the welding rod begins to melt is added to the base metal.

Arc welding requires an arc welder, a manual welding torch to hold the welding rod, and a welding surface to protect the worker's eyes from the arc light. Arc welding machines also require a power source, so captire cords and captire drums are also required. In order to perform arc welding in this manner, it is necessary to prepare various tools, and these tools must be moved each time the welding location is changed. In particular, arc welding machines are relatively heavy (even a small one weighs about 50 kg), so it requires considerable effort and time to move them, and the associated cabtire cord routing is also quite time-consuming. Such work is required.

Furthermore, arc welding is an extremely delicate operation that can only be performed by someone with special training and, in addition, is usually performed by someone with considerable experience. That is, arc welding has problems in that it requires a lot of work, such as moving many tools, and that the number of workers is limited. In addition, there is a risk of fire due to the presence of fire during the welding process, and problems such as the removal of anti-rust coatings (such as electrolytic galvanizing or paint) from the welded parts of the parts to be joined can be pointed out.

Against this background, there has been a strong need for a joining method that can replace welding. Note that it is also possible to use tapping screws as a joining method instead of welding. For example, the ALC panel mounting hardware is sewn onto the mounting base using tapping screws using an electric drill. However, it is not easy to sew self-tapping screws to a steel material such as a mounting base, and it cannot be said that the workability is better than welding.

An object of the present invention is to solve the problems faced by the prior art, namely, an adhesive panel wall structure and a method for installing adhesive panel materials, in which panel materials can be easily installed without the need for welding work. The goal is to provide the following. Furthermore, adhesive fixation may be released due to unforeseen circumstances such as the adhesive burning due to fire, but it is an object of the present invention to provide a technique that can prevent panel materials from falling even under such conditions. It is one of the

The present invention was made based on the idea that members are joined and fixed together using an adhesive instead of welding, and is based on an idea never seen before.

The adhesive panel wall structure of the present invention is a wall structure in which the panel material is fixed to the mounting base by adhesively fixing the mounting jig included in the panel material to the mounting base. This mounting jig includes a locking tool provided with an insertion hole and a bolt material, and is attached to the panel material so that the locking tool can rotate around the bolt. The locking tool has left and right arms extending left and right in a posture in which the mounting jig is adhesively fixed to the mounting base. Then, when the adhesive fixation between the mounting jig and the mounting base is released and the locking tool rotates around the bolt, the left and right arms that rotated in the same way come into contact with the mounting base, causing the panel material to fall (mounting (falling in the opposite direction to the base) can be prevented.

The adhesive panel wall structure of the present invention may also be constructed using a catch with a lower arm formed therein. This lower arm is a member that extends downward in a posture in which the mounting jig is adhesively fixed to the mounting base. In this case, when the adhesive fixation between the mounting jig and the mounting base is released and the locking tool rotates around the bolt, the similarly rotated lower arm comes into contact with the mounting base, causing the panel material to fall ( (Toppling in the opposite direction from the mounting base) can be prevented.

The adhesive panel wall structure of the present invention is a wall structure in which the panel material is fixed to the mounting base by adhesively fixing the mounting jig included in the panel material to the mounting base. This mounting jig includes a locking tool provided with an insertion hole and a bolt material, and is attached to the panel material so that the locking tool can rotate around the bolt. Incidentally, rotation prevention protrusions are provided on both sides of the mounting jig adhesively fixed to the mounting base among the panel material and the mounting base. When the adhesive fixation between the mounting jig and the mounting base is released, the anti-rotation protrusion prevents the rotation of the locking tool, causing the panel material to fall (fall in the opposite direction to the mounting base). can be prevented.

The adhesive panel material installation method of the present invention is a method of installing a panel material on a mounting base using an installation jig, and is a method comprising an adhesive application step, a panel material placement step, and a panel material installation step. Note that the mounting jig includes a locking tool provided with an insertion hole and a bolt material, and is attached to the panel material so that the locking tool can rotate around the bolt. Further, the locking tool has left and right arms extending left and right in a posture in which the mounting jig is adhesively fixed to the mounting base. In the adhesive application process, adhesive is applied to the area of the mounting jig that comes into contact with the mounting base (or within the area of the installation base that comes into contact with the mounting jig), and in the panel material placement process, the panel materials are planned. In the panel material installation process, the panel material is installed on the mounting base by adhesively fixing the mounting jig and the mounting base. When the adhesive fixation between the mounting jig and the mounting base is released, the anti-rotation protrusion prevents the rotation of the locking tool, causing the panel material to fall (fall in the opposite direction to the mounting base). can be prevented.

The adhesive panel material installation method of the present invention can also be a method that further includes a step of forming anti-rotation protrusions. In the rotation prevention protrusion forming step, rotation prevention protrusions are formed on both sides of the mounting jig adhesively fixed to the mounting base among the panel material and the mounting base. In this case, when the adhesive fixation between the mounting jig and the mounting base is released, the anti-rotation protrusion prevents the rotation of the locking tool, causing the panel material to fall (in the opposite direction from the mounting base). ) can be prevented.

The adhesive panel wall structure and adhesive panel material installation method of the present invention have the following effects.
(1) Since no welding work is required, the work can be done extremely easily and in a short time. Further, the number of workers is not limited, and there is no fear of fire during the work.
(2) By applying the adhesive according to the specifications designed in advance, sufficient required yield strength (strength) can be obtained, and as a result, a structural frame with sufficient strength can be obtained. In addition, through various tests conducted by the inventors, it has been confirmed that the adhesive fixing has the proof strength required for installing the panel material on the frame.
(3) Curing time can be adjusted by adjusting the adhesive composition. This will shorten the critical path of the entire process and shorten the construction period until the structural frame is completed.
(4) Even if the adhesive fixation is released due to fire or the like, the panel material can be prevented from falling over.

An example of an embodiment of the adhesive panel wall structure and the adhesive panel material installation method of the present invention will be described based on the drawings.

1. Overall Overview FIG. 1 is a front view showing a panel material 100 installed on a structural frame (beams and columns). The panel material 100 is a secondary product panel for architectural walls, such as an ALC panel, a precast concrete board, an extruded cement panel (ECP), or a spuncrete concrete board. As shown in this figure, in the center of the panel material 100, there are mounting hardware (hereinafter referred to as "mounting jig 200" to include those made of materials other than metal), one on the top and one on the top. The panel material 100 is installed on the structural frame by fixing the mounting jig 200 to the mounting base 300, which is provided and fixed to the structural frame, with an adhesive.

The portion where the mounting jig 200 is fixed to the mounting base 300 (hereinafter referred to as a “joint portion”) can have several structural types. For example, FIG. 2 shows an example of the structure of the upper joint part of the panel material 100, in which an angle steel serving as the mounting base 300 is fixed to the lower surface of the H-shaped steel serving as the structural frame 400, and the angle iron serving as the mounting base 300 is A jig 200 is fixed with adhesive. The mounting jig 200 shown in this figure is formed of a bolt material 210 and a plate-shaped locking tool 220. plate R)" and is attached to the panel material 100 by bolt materials 210. Specifically, the bolt material 210 that has penetrated into the anchor hole of the panel material 100 is passed through the insertion hole provided in the locking tool 220, that is, the fastening tool 220 is attached to the panel material 100 via the bolt material 210. It is. Alternatively, the bolt material 210 may be inserted into the anchor hole of the panel material 100 with the bolt material 210 passed through the insertion hole of the locking tool 220. Then, a part (web) of the mounting base 300 is accommodated using the step of the locking tool 220, and the locking tool 220 and the mounting base 300 are adhesively fixed at this accommodated location. By housing the mounting base 300 within the locking tool 220, there is no gap between the members, and the contact surfaces of the locking tool 220 and the panel material 100, as well as the mounting base 300 and the panel material 100, are on the same surface ( This results in a so-called flush surface.

FIG. 3 is a partially detailed view showing an example of the structure of the lower joint of the panel material 100. In this case as well, a lightning plate (e.g. lightning plate R) is used as the mounting jig 200, and after storing a part of the mounting base 300 in the locking tool 220, the locking tool 220 and the mounting base 300 are Fixed with adhesive. Although panel material 100 and bolt material 210 are omitted in FIG. 3, similar to FIG. Fasteners 220 are attached to panel material 100. Of course, also in this case, the bolt material 210 may be inserted into the anchor hole of the panel material 100 while passing through the insertion hole of the locking tool 220.

FIG. 4 is a partially detailed view showing an example of the structure of the upper joint part and the lower joint part. This structural type is especially used in areas where upper and lower floors meet. The lower joint portion of the upper layer panel material 100U shown in FIG. 4 is adhesively fixed using the upper layer mounting base 300U fixed to the upper flange of the structural frame 400, and the mounting jig 200 (upper layer mounting jig 200U) The structure is the same as that shown in FIG. 3 using a lightning plate (for example, lightning plate R). The upper joint part of one lower layer panel material 100L also has a structure similar to that shown in FIG. In No. 4, the top surface (top) position of the panel material 100 is different. In FIG. 2, the top of the panel material 100 is located at approximately the same height as the lower flange surface of the structural frame 400, but in FIG. The lower layer mounting jig 200L and the lower layer mounting base 300L are adhesively fixed at a position slightly lower than the top of the lower layer panel material 100L. In this way, the positions of the upper joint part and the lower joint part can be appropriately designed depending on the situation, such as the balance with the upper floors.

FIG. 5 is a perspective view showing the structure of the upper joint portion of the panel material 100, and showing an example in which a lightning plate is not used as the mounting jig 200. The mounting jig 200 when the lightning plate is not used can be formed by a flat plate (locking tool 220) having an insertion hole 230, a bolt material 210, and a receiving plate 240. As shown in FIG. 6, this receiving plate 240 has an L-shape in cross-sectional view, and is composed of a shelf section 240S in a substantially horizontal position and two wing plate sections 240W connected at both ends thereof in a substantially vertical position. be done. Then, the back side of the blade plate part 240W is adhesively fixed to the mounting base 300, and a flat plate (locking tool 220) is inserted into the gap (groove) created between the two blade plate parts 240W. It is also adhesively fixed to the mounting base 300 on the back side. This flat plate is anchored to the panel material 100 by bolts 210 passed through the insertion holes 230 of the flat plate. In addition, in order to install another panel material 100 on top of the panel material 100 shown in FIG. It is preferable to fix the lightning plate TP by adhesion.

FIG. 7 is a partially detailed view showing an example of the structural type of the upper joint portion of the panel material 100 disposed directly below the structural frame 400. This construction type is particularly adopted when the panel material 100 is used as a partition wall. In this structural type, a lightning plate is also used as the mounting jig 200, and the structure is basically similar to that in FIGS. 2 and 4, but the mounting base 300 is placed near the center of the lower flange of the structural frame 400. This is different from FIGS. 2 and 4 in that the panel material 100 is fixed and located inside the angle iron that is the mounting base 300 (inside the space formed by the flange and web). With this arrangement, the panel material 100 can be compactly accommodated directly under the structural frame 400.

Further, the mounting base 300 can be adhesively fixed to the structural frame 400, and in this case, as shown in FIGS. 2 and 4, the upper surface side of the flange of the mounting base 300 is adhesively fixed to the lower surface side of the lower flange of the structural frame 400. Alternatively, as shown in FIG. 9, the lower surface side of the flange of the mounting base 300 can be adhesively fixed to the upper surface side of the lower flange of the structural frame 400. If you try to join the structure shown in Figure 9 by welding, the workability will be extremely poor because it will be difficult to apply the welding rod to the specified position (in some cases, it will be impossible to join), but if you use adhesive, it will be easier to join. It is possible to do this.

2. Adhesive Panel Wall Structure The adhesive panel wall structure of the present invention will be described in detail below. The adhesive type panel wall structure of the present invention is a panel wall structure in which a panel material 100 is attached and fixed to a base 300 using an adhesive, and more specifically, a mounting jig 200 provided on the panel material 100 and a mounting base 300 are used. In this structure, the panel material 100 is fixed to the mounting base 300 by adhesively fixing. As explained above, the joint (the location where the mounting jig 200 is fixed to the mounting base 300) can have several structural types, and in the adhesive panel wall structure of the present invention, these various structural types can be used. (For example, FIGS. 1 to 4, FIG. 7, and FIG. 9) can be employed.

The adhesive panel wall structure of the present invention includes the panel material 100, the mounting jig 200, and the mounting base 300 shown in FIG. In FIG. 1, the mounting jig 200 is provided in the center of the panel material 100, one at the top and one at the top, but the adhesive panel wall structure of the present invention is not limited to this. A structure may also be provided in which a mounting jig 200 is provided.

The mounting jig 200 constituting the adhesive panel wall structure includes a bolt material 210 and a plate-shaped locking tool 220, and is attached to a part of the panel material 100. This panel material 100 is provided with an anchor hole, and the locking tool 220 is provided with an insertion hole, and after penetrating into this insertion hole, the bolt material 210 is inserted into the anchor hole. That is, the locking tool 220 is sewn to the panel material 100 using the bolt material 210. Note that there is a slight margin (so-called play) between the insertion hole 230 provided in the locking tool 220 and the bolt material 210, so that the locking tool 220 can freely rotate around the bolt material 210. .

For example, as shown in FIG. 2, the locking tool 220 can have a shape having two surfaces with different levels in cross-sectional view. As a result, a part (web) of the mounting base 300 can be accommodated by using the step of the locking tool 220, and the locking tool 220 and the mounting base 300 can be adhesively fixed at this accommodated location, and between the members. There is no gap, and the contact surfaces of the locking tool 220 and the panel material 100, as well as the mounting base 300 and the panel material 100, are on the same surface (so-called flush).

The mounting jig 200 attached to the panel material 100 is adhesively fixed to the mounting base 300 fixed to the structural frame 400. As a result, the panel material 100 is installed on the mounting base 300 (that is, the structural frame 400), and the adhesive panel wall structure of the present invention is formed. Note that the adhesive used here is not particularly limited, and conventionally known adhesives can be used, such as urethane-based, acrylic-based, epoxy-based, silicone-based, modified silicone-based, vinyl acetate-based, rubber-based, etc. can be exemplified. Further, this adhesive may be used in a form suitable for each site, such as a solvent volatilization type, a chemical reaction type, or a heat melting type.

By the way, bonding with adhesives is an extremely excellent method as it is easy to construct and exhibits sufficient bonding strength, but the adhesive fixation may be released due to unforeseen circumstances such as the adhesive being burned due to a fire. It also has FIG. 13(a) is a front view and side view showing the adhesive panel wall structure in a normal state, and FIG. 13(b) is a front view and side view showing the adhesive panel wall structure in a state where the adhesive fixation is released. It is a diagram. When the adhesive fixation is released, that is, when the locking tool 220 is detached (peeled off) from the mounting base 300, the locking tool 220 moves around the bolt material 210, as shown in the front view of FIG. 13(b). Rotate. As a result of the rotation of the locking tool 220, the panel material 100 tends to fall to the side opposite to the mounting base 300 (hereinafter referred to as the "non-structural side") as shown in the side view of FIG. 13(b). . If the panel material 100 falls over, things there may be broken, or people present may be injured.

Therefore, in order to prevent the panel material 100 from falling toward the non-structural side even when the adhesive fixation is released, it is preferable to form an arm projecting outward on the locking tool 220. FIG. 14(a) is a front view showing the mounting jig 200 on which the left and right arms 250 are formed, FIG. FIG. 3 is a front view showing the mounting jig 200 in a rotated state while being attached to the material 100. The left and right arms 250 shown in FIG. 14 are formed to extend from the locking tool 220 to the left and right (however, to the left and right when the mounting jig 200 is adhesively fixed to the mounting base 300).

By providing the left and right arms 250 on the locking tool 220, even if the adhesive fixation is released and the mounting jig 200 further rotates, one of the left and right arms 250 will come into contact with the mounting base 300, so that the panel material 100 This prevents the vehicle from falling toward the non-structural side. In FIG. 14(c), the mounting jig 200 is rotated approximately 45 degrees counterclockwise, but the left and right arms 250 (right side) and a portion of the locking tool 220 are in contact with the mounting base 300, so Panel material 100 cannot tip over to the non-structural side. Furthermore, even if the mounting jig 200 is further rotated counterclockwise (for example, rotated 90 degrees), the left and right arms 250 (right side) are in contact with the mounting base 300, so the panel material 100 still falls to the non-structural side. Can not do it. In addition, when the locking tool 220 has a two-sided shape with different levels (FIG. 2), the left and right arms 250 and the locking tool 220 are preferably formed to have different steps in cross-sectional view, as shown in FIG. 14(b). . Thereby, when the mounting jig 200 rotates, the left and right arms 250 can suitably accommodate a portion (web) of the mounting base 300.

The left and right arms 250 provided on the locking tool 220 are not limited to the shape shown in FIG. 14 (approximately rectangular), but may also be semicircular (or semielliptical) in plan view as shown in FIG. 15(a). , as shown in FIG. 15(b), it can be T-shaped in plan view, or it can be designed in various other shapes. Further, as shown in FIG. 15C, left and right arms 250 may be provided at two locations on each side of the locking tool 220, or left and right arms 250 may be provided at three or more locations on each side. Note that FIG. 15 is a front view of the mounting jig 200 in a position where it is adhesively fixed to the mounting base 300.

In addition to the left and right arms 250, the locking tool 220 can also be formed with an arm that projects downward. FIG. 16 is a side view showing the mounting jig 200 with the lower arm 260 formed thereon. As shown in this figure, the lower arm 260 is formed to extend downward from the locking tool 220 (downward when the mounting jig 200 is adhesively fixed to the mounting base 300).

By providing the lower arm 260 on the locking tool 220, even if the adhesive fixation is released and the mounting jig 200 is further rotated 180 degrees (that is, upside down), the lower arm 260 can come into contact with the mounting base 300. It is possible to prevent the panel material 100 from falling toward the non-structural side. That is, when the mounting jig 200 starts rotating, the left and right arms 250 and part of the locking tool 220 first come into contact with the mounting base 300, and as the mounting jig 200 further rotates, only the left and right arms 250 touch the mounting base. 300 and the panel material 100 is turned upside down, the lower arm 260 contacts the mounting base 300 to prevent the panel material 100 from falling toward the non-structural side. In addition, when the locking tool 220 has a two-sided shape with different levels (FIG. 2), the lower arm 260 and the locking tool 220 may be formed to have different levels in a cross-sectional view, as shown in FIG. 16. Thereby, when the mounting jig 200 rotates, the lower arm 260 can suitably accommodate a portion (web) of the mounting base 300.

In addition to using the locking tool 220 provided with the left and right arms 250 and the lower arm 260, it is also possible to prevent the panel material 100 from falling by using a rotation prevention protrusion. FIG. 17(a) is a front view showing anti-rotation protrusions 500 installed on both sides of the mounting jig 200 fixed with adhesive on the mounting base 300, and FIG. FIG. 4 is a front view showing anti-rotation protrusions 500 installed on both sides of the mounting jig 200.

By installing anti-rotation projections 500 on both sides of the adhesively fixed mounting jig 200, even if the adhesive fixation is released and the mounting jig 200 attempts to rotate, the rotation prevention projections 500 act as a barrier to prevent installation. The jig 200 cannot rotate, and as a result, it is possible to prevent the panel material 100 from falling toward the non-structural side. Note that the anti-rotation protrusions 500 are provided on both sides of the mounting jig 200 (however, on both sides when adhesively fixed to the mounting base 300), and are installed on the mounting base 300 side as shown in FIG. 17(a). Alternatively, as shown in FIG. 17(b), it may be installed on the panel material 100 side, or it may be installed on both the mounting base 300 and the panel material 100.

The rotation prevention protrusion 500 may be formed to protrude from the surface of the mounting base 300 or the panel material 100 so as to act as a barrier against rotation of the mounting jig 200. Although the anti-rotation protrusion 500 is shown in a triangular shape in FIG. 17 for convenience, it can of course be designed in various shapes as long as it can prevent the attachment jig 200 from rotating.

3. Adhesive Panel Material Installation Method The adhesive panel material installation method of the present invention will be described in detail below. Note that the adhesive panel material installation method of the present invention can also be used as a method for constructing the adhesive panel wall structure described so far, and therefore, explanations that overlap with those explained for the adhesive panel wall structure will be omitted. Therefore, only contents specific to the adhesive panel material installation method of the present invention will be explained. That is, the contents not described here are the same as those explained in "2. Adhesive panel wall structure". Further, the adhesive panel material installation method of the present invention involves adhesively fixing the mounting jig 200 and the mounting base 300, and can be broadly classified into two types depending on the application form of the adhesive. Therefore, they will be described in order as a "first embodiment" and a "second embodiment", respectively.

(First embodiment)
FIG. 8 is a flowchart showing the main process flow of the first embodiment. First, the mounting base 300 made of angle iron or the like is fixed to the structural frame 400 made of H-beam steel or I-beam steel (Step 110). At this time, the "adhesive mounting base fixing method" can be carried out to adhesively fix the structural frame 400 and the mounting base 300 using an adhesive. According to this adhesive type installation base fixing method, no welding work is required, so the work of fixing the mounting base 300 can be done easily and in a short time, and anyone (such as a person without special training) can do the work. , and there is no risk of fire occurring during work, and various other effects can be expected, making it suitable. Note that the method for fixing the mounting base 300 is not limited to the adhesive type, and the structural frame 400 and the mounting base 300 may be fixed by welding as in the conventional method. Furthermore, if the mounting base 300 has already been installed, this step (Step 110) can be omitted.

When fixing the mounting base 300 to the structural frame 400 using the “adhesive installation base fixing method”, as shown in FIGS. The lower side of the flange of the mounting base 300 can be adhesively fixed to the upper side of the lower flange of the structural frame 400 as described above (FIG. 9). If you try to join the structure shown in Figure 9 by welding, the workability will be extremely poor because it will be difficult to apply the welding rod to the specified position (in some cases, it will be impossible to join), but if you use adhesive, it will be easier to join. I can do it. Note that there are no particular limitations on the adhesive used here, and conventionally known adhesives can be used. For example, urethane-based, acrylic-based, epoxy-based, silicone-based, modified silicone-based, vinyl acetate-based, rubber-based, etc. can be exemplified, and it is particularly preferable to use urethane-based, acrylic-based, epoxy-based, and silicone-based. Further, this adhesive may be used in a form suitable for each site, such as a solvent volatilization type, a chemical reaction type, or a heat melting type.

Once the mounting base 300 is fixed, the surface of the mounting base 300 is cleaned to remove unnecessary substances such as oil and dust, and the surface of the mounting jig 200 that comes into contact with the mounting base 300 (hereinafter referred to as (referred to as the "contact surface") according to the planned specifications (adhesive to be used, coating thickness, etc.) (Step 120). Alternatively, adhesive may be applied to the surface of the mounting base 300 that comes into contact with the mounting jig 200 (contact surface), or adhesive may be applied to the contact surfaces of the mounting jig 200 and the mounting base 300, respectively. good. Note that there are no particular limitations on the adhesive used here, and conventionally known adhesives can be used. For example, urethane-based, acrylic-based, epoxy-based, silicone-based, modified silicone-based, vinyl acetate-based, rubber-based, etc. can be exemplified. Further, this adhesive may be used in a form suitable for each site, such as a solvent volatilization type, a chemical reaction type, or a heat melting type.

When the adhesive is applied to the contact surface, by placing the panel material 100 at the planned position, the mounting jig 200 and the mounting base 300 come into contact at the contact surface (Step 130), and the adhesive on this contact surface hardens. The mounting jig 200 and the mounting base 300 are fixed, that is, the panel material 100 is installed on the structural frame 400 (Step 140). In addition, instead of applying adhesive to the contact surface of the mounting jig 200 (or the mounting base 300), after the panel material arrangement process (Step 130), the mounting jig 200 is brought into contact with the mounting base 300, and the mounting jig The adhesive may be filled from the gap between the mounting base 200 and the mounting base 300.

The series of steps explained above is repeated until all the planned number of panel materials 100 are installed, and the work is completed.

(Second embodiment)
FIG. 10 is a flowchart showing the main process flow of the second embodiment, and FIG. 11 is a step diagram explaining each process shown in this flowchart. First, as in the first embodiment, the mounting base 300 (for example, angle iron or the like) is fixed to the structural frame 400 (for example, H-section steel or I-section steel) (Step 210). At this time, the "adhesive mounting base fixing method" can be carried out to adhesively fix the structural frame 400 and the mounting base 300 with the adhesive described in the first embodiment, or the structural frame 400 and the mounting base can be fixed as usual. 300 may be fixed by welding. Note that if the mounting base 300 has already been installed, this step (Step 210) can be omitted.

Once the mounting base 300 is fixed as shown in FIG. 11(a), the panel material 100 is placed in the planned position as shown in FIG. 11(b), and the mounting jig 200 is brought into contact with the mounting base 300. (Step 220). At this time, if the mounting jig 200 is made up of a bolt material 210 and a locking tool 220 (for example, a lightning plate), the locking tool 220 is rotated around the bolt material 210 (counterclockwise in the figure). Therefore, it is preferable to bring the mounting jig 200 into contact with the mounting base 300. Since there is some margin (so-called play) between the insertion hole 230 provided in the locking tool 220 and the bolt material 210, the locking tool 220 can rotate freely.

When the mounting jig 200 is brought into contact with the mounting base 300, markings are made on the surface of the mounting base 300 so as to surround the area where the mounting jig 200 contacts the mounting base 300 (Step 230). That is, the area to which the adhesive should be applied on the surface of the mounting base 300 is clearly specified here.

After marking the adhesive application range, as shown in FIG. 11(c), the locking tool 220 is rotated around the bolt material 210 (clockwise in the figure) while the panel material 100 is placed at the planned position. By doing so, the mounting jig 200 is temporarily removed from the mounting base 300. Then, adhesive is applied according to the planned specifications based on the marking MK described above (Step 240). Note that the adhesive used here can be selected from the same adhesive as that described in the first embodiment.

After applying the adhesive, as shown in FIG. 11(d), by rotating the locking tool 220 around the bolt material 210 again (counterclockwise in the figure), the mounting jig 200 is attached to the mounting base 300. bring it into contact. Then, as the adhesive hardens, the mounting jig 200 and the mounting base 300 are fixed, that is, the panel material 100 is installed on the structural frame 400 (Step 250). When providing the anti-rotation projections 500 shown in FIG. 17, the anti-rotation projections 500 are preferably installed on both sides of the mounting jig 200 (Step 260) after the panel material is installed (Step 250). Specifically, the anti-rotation protrusion 500 can be formed by adhesively fixing a protrusion (for example, a nut, a laminate, etc.) to the mounting base 300 or the surface of the panel material 100. Alternatively, the anti-rotation protrusion 500 can also be formed by fixing screws or the like to the mounting base 300, driving nails into the panel material 100, or installing other protrusions.

Up to this point, we have described an example in which adhesive is applied to the contact surface of the mounting base 300, but instead of this, it is also possible to apply adhesive to the contact surface of the mounting jig 200, or to connect the mounting jig 200 and the An adhesive can also be applied to each contact surface of the base 300. Note that when applying adhesive to the contact surface of the mounting jig 200, there is no need to mark the surface of the mounting base 300, that is, the temporary placement process of panel materials (Step 220) and marking process (Step 230) are omitted. can do.

The series of steps explained above is repeated until all the planned number of panel materials 100 are installed, and the work is completed.

If the mounting base 300 is made of steel and a rust preventive material is applied to its surface, in order to ensure that the adhesive has sufficient adhesive strength, the area of the mounting base 300 that the adhesive comes into contact with (hereinafter referred to as "contact") is It is recommended to remove the anti-corrosion material from the areas (referred to as "areas"). In the case of the second embodiment, since the adhesive range is marked, the rust preventive material can be removed using this as the contact area, but in the case of the first embodiment, the adhesive range is not marked. Therefore, when performing the rust preventive material removal process in the case of the first embodiment, it is preferable to remove the rust preventive material after indicating the contact area by measurement or the like. When removing the rust preventive material, it is desirable to perform another rust preventive treatment such as applying a rust preventive spray after adhering the mounting base 300.

4. Confirmation Test The results of tests conducted by the inventors of the present invention in order to confirm the effects of the present invention will be explained below.

(Test method)
After making some improvements while referring to "JIS A5416 Lightweight Aerated Concrete Panel (ALC Panel)," a loading test was conducted on a test model created using the adhesive panel material installation method of the present invention. Specifically, a test model was created by adhesively fixing an ALC panel (panel material 100) measuring 100 (thickness) x 600 (width) x 2,990 (height) mm to angle iron (mounting base 300). are doing. Note that a reactive acrylic adhesive was used as the adhesive, and the curing period for the adhesive was 24 hours. This test model was tested using a method of applying force using two lines divided into four equal parts, with reference to the panel bending strength test specified in the above-mentioned JIS. Note that in the JIS test method, one end of the ALC panel is fixed and the other end is placed on a roller, but in this test, both ends of the ALC panel are adhesively fixed to angle iron. However, in order to distinguish between the fulcrums on both sides, the side corresponding to the fixed fulcrum in the JIS test method will be referred to as the "reference side", and the side corresponding to the roller fulcrum will be referred to as the "variable side".

(Test results)
As a result of the test, the attachment strength on the reference side was 2,531N, and the attachment strength on the variable side was 3,610N. Generally, the installation strength required for a partition panel with a thickness of 100 mm is 1,050 N/location (allowable load 700 N/m ² × width 0.6 m × length 5.0 m ÷ 2 locations), and the test model according to the present invention When compared with the standard side, it was about 2.4 times as much, and on the variable side it was about 3.4 times, confirming that the mounting strength was sufficient. Figure 12(a) shows the results of the attachment strength.

FIG. 12(b) is a diagram showing the relationship between displacement and load at the fixed part of the ALC panel and angle iron, and is a graph showing that the adhesive specifications according to the present invention and the conventional welding specifications have the same strength. Further, FIG. 12(c) is a diagram showing the relationship between displacement and load at the center of the ALC panel, and is also a graph comparing the adhesive specification according to the present invention and the conventional welding specification. As can be seen from these figures, the adhesive specifications according to the present invention and the conventional welding specifications show almost the same tendency, that is, it was confirmed that the adhesive specifications according to the present invention have the same effect as the conventional welding specifications. .
