Mode for Carrying Out the Invention

[0026] <First Embodiment> Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, with reference to FIGS. 1 and 2, a prefabricated panel used in the construction method according to the present invention will be described. FIG. 1 is an exploded perspective view showing the configuration of a prefabricated panel manufactured by the construction method of the first embodiment. FIG. 2 is a view of the prefabricated panel of FIG. 1 seen from the front side. In FIG. 1, the reinforcing coating layer is drawn in a state where a part thereof is cut away. In FIG. 2, the prefabricated panel is drawn in a state where the reinforcing coating layer is omitted so that the configuration can be easily understood. The vertical direction in the figure corresponds to the vertical direction.

[0027] As shown in FIG. 1, the prefabricated panel S100 of the present embodiment includes a prefabricated wall 10, a frame body 20, and a reinforcing coating layer 30. The prefabricated panel S100 is used as an inner wall or an outer wall of a building.

[0028] (Prefabricated Wall) The prefabricated wall 10 has a plurality of prefabricated members 11 arranged in the horizontal direction and the vertical direction. The prefabricated members 11 are building bricks or block materials, and are, for example, rectangular parallelepipeds. The density of the prefabricated members 11 is, for example, 1.5 g / cm 3The above is the case. The assembled material 11 is not a lightweight material such as a urethane foam block material, for example, but a relatively heavy block material. The assembled materials 11 are fixed to each other by a filling material such as mortar to form one assembled wall 10. Of course, the assembled materials 11 may also be fixed to each other by a reinforcing member such as a reinforcing bar, plaster applied to the surface, and / or joint mortar.

[0029] In the present invention, an assembled material having a density of 0.3 g / cm 3 or more may be used. The assembled material 11 may be wood, AAC foamed concrete, or the like.

[0030] The assembled wall 10 is disposed inside the frame body 20. The assembled wall 10 is fixed to the frame body 20. Thereby, a wall in which the assembled wall 10 and the frame body 20 are integrated is formed. To fix the assembled wall 10 to the frame body 20, mortar filled between the assembled wall 10 and the frame body 20 may be used, or a connecting tool for mechanically connecting the assembled wall 10 and the frame body 20 may be used. In FIG. 2, the inner circumference of the frame body 20 is drawn as a plane, but a concave groove may be formed in the inner circumference of the frame body 20, and the outer peripheral portion of the assembled wall 10 may enter the groove.

[0031] The amount of the reinforcing member (for example, a reinforcing bar) in the assembled panel S100 is, for example, more than 0 kg and 50 kg or less with respect to the volume of 1 m 3 of the assembled wall 10. The amount of the filling material in the assembled panel S100 is, for example, more than 0 t and 2.5 t or less (preferably more than 0 t and 1.7 t or less) with respect to the volume of 1 m 3 of the assembled wall 10. By adjusting the amounts of the reinforcing member and / or the filling material within such ranges, it is possible to achieve weight reduction of the wall while improving the strength of the wall.

[0032] (Frame body) The frame body 20 is a member formed in a quadrilateral shape surrounding the built-up wall 10. The frame body 20 has an upper frame 21, a lower frame 22, and a pair of side frames 23. The upper frame 21 and the lower frame 22 extend in the horizontal direction. The side frames 23 extend in the vertical direction. These frames may be connected to each other by fixtures such as screws, or may be fixed to each other by welding or the like. The material of the frame body 20 is arbitrary, and may be, for example, PC (precast concrete), metal, or wood.

[0033] The frame body 20 may also be formed by stacking a plurality of built-up members and bonding the built-up members on the outermost four sides with a high-strength resin to form a frame.

[0034] Figure 3 is a schematic diagram for explaining the relationship between the built-up wall 10 and the frame body 20. The thickness dimension d2 of the frame body 20 is longer than the thickness dimension d1 of the built-up wall 10 (although not shown in Figure 3, it includes the thickness of the reinforcing coating layer and / or plaster. When mortar is applied to the wall surface, it also includes the thickness of the mortar). When the thickness dimension d2 of the frame body 20 is longer than the thickness dimension d1 of the built-up wall 10 and the built-up wall 10 is arranged inside the frame body 20 as shown in Figure 3, the following advantages can be obtained. In the configuration of Figure 3, the built-up wall 10 is arranged inside the frame body 20 such that the front surface of the built-up wall 10 is located more inside than the front surface of the frame body 20 and the rear surface of the built-up wall 10 is located more inside than the rear surface of the frame body 20. According to such a configuration, the built-up wall 10 is arranged inside the frame body 20, the front surface of the built-up wall 10 does not protrude outside the front surface of the frame body 20, and the rear surface of the built-up wall 10 also does not protrude outside the rear surface of the frame body 20. Therefore, the effect that the built-up wall 10 is less likely to be damaged during work or transportation can be obtained. It should be noted that the configuration of Figure 3 is merely an example of the present invention, and it is also preferable in one form that the wall surface of the built-up wall 10 and the surface of the frame body 20 are the same surface.

[0035] (Reinforcing coating layer) The reinforcing coating layer 30 is a coating layer provided on the wall surface of the prefabricated wall 10 to reinforce the prefabricated wall 10. The reinforcing coating layer 30 may be formed on both sides of the prefabricated wall 10 or on one side. In this embodiment, the reinforcing coating layer 30 is formed on one side. The reinforcing coating layer 30 may be formed only on a part of the wall surface of the prefabricated wall 10 or on the entire surface.

[0036] The paint for forming the reinforcing coating layer 30 is applied to the prefabricated wall 10 and dried, whereby the reinforcing coating layer 30 with a predetermined thickness is formed on the prefabricated wall 10. By forming the reinforcing coating layer 30 so as to adhere to the wall surface, at least one of the rigidity, strength, and deformability of the prefabricated wall 10 is enhanced. The reinforcing coating layer 30 is, for example, a layer of fiber-reinforced resin. Specifically, the reinforcing coating layer 30 contains one or more kinds of fiber materials. Before curing, the reinforcing coating layer 30 has fluidity and is applied to the prefabricated wall 10 by, for example, a roller, a brush, a brush, or a spray. Note that the curing of the paint may be curing by a curing agent, curing by drying, or curing by a combination of drying and a curing agent.

[0037] (Specific example of the reinforcing coating layer 30) Specifically, the material of the reinforcing coating layer 30 may be as follows. In the reinforcing coating layer 30, glass fibers are mixed into the paint to form a slurry state. The paint may be a so-called elastic paint in which the coating surface exhibits a single-layer rubbery state. The paint is preferably, for example, an acrylic paint mainly composed of a crosslinkable acrylic emulsion. The diameter of the glass fiber is, for example, 1 μm to 20 μm (1 μm or more and 20 μm or less). The length of the glass fiber is, for example, in the range of 1 mm to 20 mm. By mixing glass fibers into an acrylic-based paint, a slurry in which the glass fibers are suspended in the paint can be obtained. The weight ratio of the glass fiber to the weight of the paint is, for example, 1% to 40%.

[0038] In the process of applying the reinforcing coating layer 30, as an example, a primer material may be applied to the prefabricated wall 10. A paint in which glass fibers are suspended is applied after the primer has dried. The paint of the crosslinkable acrylic emulsion forms a single-layer that firmly adheres to the prefabricated wall 10 regardless of the surface morphology of the wall after application. The layer formed in this way is excellent in waterproof performance. Note that as the paint, a urethane-based paint may be used instead of the acrylic paint.

[0039] The reinforcing coating layer 30 may be formed such that a plurality of layers with different properties are laminated. The reinforcing coating layer 30 may not be formed directly on the surface of the prefabricated material 11, but may be formed on a layer such as mortar formed on the surface of the prefabricated material 11.

[0040] Part (preferably more than half by mass) or all of the resin contained in the fiber-reinforced resin that can constitute the reinforcing coating layer 30 is preferably an elastic resin, and an acrylic resin, a silicone resin, an acrylic silicone resin, a urethane resin, or a natural resin (latex paint) is preferred.

[0041] With respect to the total mass of the reinforcing coating layer 30, the resin content is preferably 30 to 99% by mass, more preferably 40 to 96% by mass, and even more preferably 55 to 93% by mass.

[0042] The fiber material contained in the fiber-reinforced resin that can constitute the reinforcing coating layer 30 may be an inorganic fiber (such as the above-mentioned glass fiber, carbon fiber, boron fiber, etc.) or an organic fiber (such as aramid fiber, plant fiber, etc.), and inorganic fiber is preferred. Part (preferably more than half by mass) or all of the fiber material is preferably inorganic fiber, and glass fiber is more preferred. The fiber material may be surface-treated to adjust the adhesion to the resin.

[0043] With respect to the total mass of the reinforcing coating layer 30, the content of the fiber material is preferably 0.3 to 6% by mass.

[0044] FIG. 4 is a perspective view showing an example of the shape of the reinforcing coating layer. The reinforcing coating layer 30 may be formed only on the wall surface of the prefabricated wall 10, or may be formed in a region extending from the wall surface of the prefabricated wall 10 to the frame body 20. Specifically, as shown in FIG. 4, the reinforcing coating layer 30 may be formed across the wall surface of the prefabricated wall 10, the upper frame 21, and the side frame 23. Although not shown in FIG. 4, the reinforcing coating layer 30 may be formed so as to contact the entire circumference of the wall surface of the frame body 20. In this way, since the reinforcing coating layer 30 is in contact with the prefabricated wall 10 and the frame body 20, it becomes difficult for the prefabricated wall 10 to come off from the frame body 20. The reinforcing coating layer 30 may be formed across the wall surface of the prefabricated wall 10 and a part of the frame body 20 (for example, the upper frame 21).

[0045] (Construction method) FIG. 5 is a flowchart showing an example of the construction method of the present invention. Hereinafter, the step of the worker installing the prefabricated panel S100 described above in the building will be described.

[0046] First, in step S1, the worker manufactures the prefabricated panel S100. This step is a step of preparing the prefabricated panel S100. The worker sequentially arranges a plurality of building blocks 11 inside the frame body 20. The worker fills, for example, mortar between the building blocks 11. Reinforcing bars may be arranged in the vertical direction or the horizontal direction. The worker also fixes the building blocks 11 located on the outer peripheral portion of the prefabricated wall 10 and the frame body 20. For fixing the building blocks 11 and the frame body 20, mortar may be used as described above, or materials other than mortar may be used. Through such a process, the prefabricated panel S100 in which the prefabricated wall 10 is fixed to the frame body 20 is manufactured.

[0047] Step S1 may be performed inside the building or near the building where the prefabricated panel S100 is installed, or may be performed at a location separate from the building such as a factory.

[0048] Next, in step S2, the operator forms a reinforcing coating layer 30 on the wall surface of the prefabricated wall 10. Specifically, the operator applies paint to the wall surface of the prefabricated wall 10, for example, by using a roller, a trowel, or a spray. A plurality of prefabricated panels S100 without the reinforcing coating layer 30 may be prepared, and paint may be sequentially applied to the wall surfaces of the prefabricated walls 10 of each panel.

[0049] When manufacturing the prefabricated panel S100 as shown in FIG. 4, in step S2, the operator may also form the reinforcing coating layer 30 in the region extending from the wall surface of the prefabricated wall 10 to the frame body 20. This step may be performed, for example, by a procedure of applying paint to the entire region of the reinforcing coating layer 30 in FIG. 4 (the region extending from the wall surface of the prefabricated wall 10 to the frame body 20), or may be performed by a procedure of first applying paint to the wall surface of the prefabricated wall 10 and then applying paint to the region connecting the wall surface of the prefabricated wall 10 and the frame body 20.

[0050] Next, in step S3, the operator moves the prefabricated panel S100 with the reinforcing coating layer 30 formed thereon to a predetermined position within the building. The "predetermined position" may be the installation position where the prefabricated panel S100 is installed within the building. However, in the present embodiment, as an example, the "predetermined position" is a member placement area where the prefabricated panel S100 is temporarily placed during the transportation to the installation position.

[0051] The means for moving the prefabricated panel S100 is arbitrary. However, the operator moves the prefabricated panel S100 while holding the frame body 20 of the prefabricated panel S100 with, for example, a wire or a predetermined device. By moving the prefabricated panel S100 while holding the frame body 20 instead of the prefabricated wall 10, excessive force is not applied to the prefabricated wall 10, and the prefabricated panel S100 can be moved well. Further, according to such a moving step, even when the mortar and the reinforcing coating layer 30 are not sufficiently dried and the strength of the prefabricated wall 10 is insufficient as a building material, the prefabricated panel S100 can be moved. Therefore, the working efficiency can be improved.

[0052] Next, in step S4, the operator installs the prefabricated panel S100 at the target installation position. The installation of the prefabricated panel S100 is performed, for example, by fixing the frame body 20 to a beam or a column which is a structural part of the building.

[0053] (Effect) Through the above series of steps, the prefabricated panel S100 is manufactured, and the manufactured prefabricated panel S100 is installed at a predetermined installation position in the building. In the construction method of the present embodiment, instead of directly providing a plurality of prefabricated members 11 at the target installation position as in the conventional method, it is a method of moving the prefabricated panel S100 manufactured at a location different from the installation position. Therefore, the manufacturing and installation of the prefabricated member wall can be carried out with good workability.

[0054] In the prefabricated panel S100, the reinforcing coating layer 30 is provided on the wall surface of the prefabricated wall 10, and this reinforcing coating layer 30 improves the fixing strength between the prefabricated members 11. In a structure where such a reinforcing coating layer 30 is not provided and, for example, a large number of steel bars are arranged in the prefabricated wall 10 to improve the fixing strength between the prefabricated members 11, the weight of the prefabricated panel S100 will increase. On the other hand, according to the configuration of the present embodiment using the reinforcing coating layer 30, the prefabricated panel S100 is lightened. Therefore, the effect that the handleability of the prefabricated panel S100 is improved is obtained. Note that the description regarding the effect does not exclude the use of steel bars in the present invention.

[0055] The flowchart of FIG. 5 includes the manufacturing step of the prefabricated panel S100, the forming step of the reinforcing coating layer 30, and the installation step of the prefabricated panel S100, but these steps are not essential in the construction method of the present invention.

[0056] <Second Embodiment> FIG. 6 is a perspective view showing a prefabricated panel and a holding device used in the construction method of the second embodiment. FIG. 7 is a view showing the holding device in an open state. FIG. 8 is a view showing the holding device in a closed state. As described in the first embodiment, in the present invention, the prefabricated panel S100 is moved. The prefabricated panel S100 may be lifted and moved by a holding device 50 as shown in FIG. 6.

[0057] The frame body 20 in FIG. 6 has a protruding portion 25 at the central portion of the upper frame 21. The protruding portion 25 is provided on the side surface of the upper frame 21. The protruding portion 25 protrudes in the thickness direction of the frame body 20. The protruding portion 25 is, for example, a rod-shaped member. In the example of FIG. 6, the protruding portions 25 are provided on both side surfaces of the upper frame 21, respectively.

[0058] In FIG. 6, a pair of protruding portions 25 are provided at one location on the upper frame 21, but a plurality of protruding portions 25 may be provided at a plurality of locations. The protruding portion 25 may be provided at a position other than the upper frame 21 of the frame body 20.

[0059] (Holding Device) The holding device 50 is a clamp that holds the frame body 20 of the prefabricated panel S100. The holding device 50 has a pair of contact members 51 and a link mechanism 55.

[0060] As shown in FIG. 7, the pair of contact members 51 are arranged to face each other so that the frame body 20 can be sandwiched from both sides. Since the structures of the respective contact members 51 are the same, only one of the contact members 51 will be described below. In the present embodiment, the contact member 51 is formed in a U-shape and has a contact portion 52 and a side portion 53.

[0061] The contact portion 52 is a portion that forms a contact surface that contacts the side surface of the frame body 20. The contact surface is, for example, a flat surface. A through hole 52h into which the protruding portion 25 is inserted is formed in the contact portion 52.

[0062] The side part 53 is integrally formed with the contact part 52. As shown in FIG. 7, the side part 53 is supported by a second link member 57 (details below) by a support pin P3. Specifically, the side part 53 is rotatably supported around the support pin P3. The arc-shaped long hole 53h of the side part 53 and the protrusion 57a provided on the second link member 57 and located within the long hole 53h limit the rotation range of the contact member 51. Specifically, the rotation range is limited to a direction such that the contact surface of the contact part 52 faces the side surface of the frame body 20.

[0063] As shown in FIG. 7, the long hole 53h may be formed such that the central angle a1 of the arc with respect to the horizontal plane is, for example, 60° or less, and preferably, the central angle a1 is 45° or less. In the case of such a configuration, even if the contact member 51 rotates around the support pin P3 due to the self-weight of the contact member 51, the surface of the contact part 52 does not face vertically upward or vertically downward, and the surface of the contact part 52 is inclined at, for example, 45° with respect to the horizontal plane. Therefore, when sandwiching the frame body 20 with the pair of contact members 51 from the state of FIG. 7 to the state of FIG. 8, there is an advantage that the contact member 51 is easy to attach.

[0064] The link mechanism 55 supports the pair of contact members 51. As shown in FIGS. 7 and 8, the link mechanism 55 is configured to be telescopic. In the state of FIG. 7 where the link mechanism 55 is contracted, the contact members 51 are in a state of being separated from each other. In the state of FIG. 8 where the link mechanism 55 is extended, the contact members 51 are in a state of approaching each other.

[0065] Specifically, the link mechanism 55 has a first link member 56 and a second link member 57. A pair of the first link members 56 and a pair of the second link members 57 are provided respectively.

[0066] The first link member 56 is a plate-shaped member. The first link member 56 has a linear contour shape. The first link members 56 are rotatably connected to each other by a support pin P1. A wire S is fixed to the support pin P1.

[0067] The second link member 57 is also a plate-shaped member. The second link member 57 has a J-shaped contour. The second link member 57 is connected to the first link member 56 by a support pin P2. Also, one second link member 57 and the other second link member 57 are rotatably connected to each other by a support pin P3. An abutting member 51 is attached to the end of the second link member 57.

[0068] The holding device 50 configured as described above operates as follows. The operation of the holding device 50 will be described below together with the procedure for an operator to use the holding device 50.

[0069] First, the operator places the holding device 50 on a part of the frame body 20. Specifically, the operator attaches the holding device 50 to the upper frame 21 such that the protruding portion 25 of the frame body 20 is inserted into the through hole 52h.

[0070] Next, when the operator operates a device (not shown) for moving the wire S and the wire S is pulled up, an upward force is applied to the support pin P1 and the link mechanism 55 is also pulled up. Then, as shown in FIG. 8, the link mechanism 55 deforms and the pair of abutting members 51 move closer to each other. Thus, in the link mechanism 55 of the present embodiment, when an upward force is applied to a part of the link mechanism 55, the pair of abutting members 51 sandwich the frame body 20 from both sides. According to this configuration, in addition to preventing the protruding portion 25 from falling out of the through hole 52h, the pair of abutting members 51 sandwich the frame body 20. By the step of lifting the panel in the state where the frame body 20 is sandwiched by the pair of abutting members 51 in this way, the prefabricated panel S100 can be favorably moved so as not to fall.

[0071] In particular, the holding device 50 in this example is not a structure that sandwiches the frame body 20 with a pair of abutting members 51 using a drive source such as a motor or hydraulic pressure, but a structure that moves the pair of abutting members 51 using the force for pulling up the prefabricated panel S100. Therefore, it can be realized with a simple configuration and a drive source such as a motor is not required.

[0072] In the above description, an example was given in which the holding device 50 is lifted by the wire S. However, instead of the wire S, for example, a part of a device used at a construction site (for example, an arm part of the device) may be connected to a part of the link mechanism 55, and the holding device 50 may be lifted by that device.

[0073] In FIGS. 7 and 8, an example was given in which the protruding portion 25 is inserted into the through hole 52h (in other words, the through hole (opening) is engaged with the protruding portion 25). However, the holding device may have a configuration in which the protruding portion 25 is inserted into a recess formed in, for example, the contact member 51 instead of the through hole 52h, and the protruding portion 25 is engaged with the recess.

[0074] <Modification Example 1> FIG. 9 is a diagram for explaining a first modification example. The prefabricated panel S101 in FIG. 9(a) has a filler 18 and a reinforcing coating layer 30. The filler 18 is filled between adjacent prefabricated members 11 and is, for example, mortar.

[0075] The filler 18 is filled so as to form a protruding portion 18a that protrudes from the surface of the prefabricated member 11. The protruding length of the protruding portion 18a from the surface of the prefabricated member 11 is, for example, 5% or more of the thickness of the prefabricated member 11. As a specific example, when the thickness of the prefabricated member 11 is 150 mm, the protruding length of the protruding portion 18a is 7.5 mm or more. The protruding length of the protruding portion 18a is also, for example, 20% or less of the thickness of the prefabricated member 11. As a specific example, when the thickness of the prefabricated member 11 is 150 mm, the protruding length of the protruding portion 18a is 30 mm or less. Since the protruding length is not too short, the anchor effect of the reinforcing coating layer 30 can be easily obtained sufficiently. Also, since the protruding length is not too long, the workability of the step of arranging the filler 18 is less likely to deteriorate.

[0076] The reinforcing coating layer 30 is formed so as to be in close contact with the protruding portion 18a. When the reinforcing coating layer 30 is formed so as to be in close contact with the protruding portion 18a in this way, the reinforcing coating layer 30 is less likely to peel off from the prefabricated wall 10 due to the anchor effect.

[0077] As in the prefabricated panel S102 of FIG. 9(b), the filler 18 may be filled so as to form a recessed portion 18b that is recessed from the wall surface of the prefabricated wall 10. And the reinforcing coating layer 30 may be formed so as to adhere to this recessed portion 18b. Also in the case of such a configuration, since a part of the reinforcing coating layer 30 is formed so as to enter the recessed portion 18b, the reinforcing coating layer 30 is less likely to peel off from the prefabricated wall 10.

[0078] <Modification 2> FIG. 10 is a diagram for explaining the construction method of the second modification. In the construction method of one embodiment of the present invention, in the step of moving the prefabricated panel S100, the prefabricated panel S100 may be moved with the protective plate 70 disposed on the wall surface of the prefabricated panel S100. In the example of FIG. 10, protective plates 70 are respectively disposed on both surfaces of the prefabricated panel S100.

[0079] The protective plate 70 is formed in a size that covers the wall surface of the prefabricated wall 10. The structure for fixing the protective plate 70 is not limited to a specific one. The protective plate 70 is fixed to the frame body 20 by, for example, a fixing tool (for example, a screw) not shown. The protective plate 70 has a recess 70a formed in the upper part, and the position of the protective plate 70 in the horizontal direction may be defined by fitting the protruding portion 25 into this recess 70a. In FIG. 10, an example is depicted in which the position of one protective plate 70 is defined by one protruding portion 25, but the position of the protective plate 70 may be defined by a plurality of protruding portions 25. Also, the fixing tool may fix the protective plate 70 at a plurality of positions.

[0080] As shown in FIG. 8, since the pair of contact members 51 of the holding device 50 are configured to sandwich the frame body 20, the protective plate 70 may be formed in a shape that is sandwiched together with the frame body 20 by the pair of contact members 51. Thus, according to the configuration in which the holding device 50 also serves as a member for pressing the protective plate 70, the member for pressing the protective plate 70 can be omitted or the number of members can be reduced.

[0081] The prefabricated panel S100 may be moved before the drying time of the paint of the reinforcing coating layer 30 applied to the prefabricated wall 10 elapses, that is, before the paint dries and cures. Even when moved in this way, since the protection plate 70 is provided, problems such as a member hitting the prefabricated wall 10 during movement and damaging the prefabricated wall 10 are less likely to occur.

[0082] <Modification Example 3> FIG. 11 is a diagram for explaining the construction method of the third modification example. The prefabricated panel S103 according to one embodiment of the present invention may include a locking member 21a formed on a part of the frame body 20. The locking member 21a is a protruding portion protruding upward from the upper frame 21.

[0083] In the step of installing such a prefabricated panel S103 at a predetermined installation position of a building, the locking member 21a of the frame body 20 may be fixed to a part of the structure of the building. Specifically, the locking member 21a may be fixed to a part of a beam or a ceiling (when there is an upper floor, the ceiling may be the floor of the upper floor). According to such a configuration, since the locking member 21a is fixed to a part of the structure of the building, the prefabricated panel is less likely to fall even during an earthquake or the like.

[0084] <Modification Example 4> FIG. 12 is a perspective view for explaining a modification example of the holding device. FIG. 13 is a diagram showing another configuration example of the frame body. FIG. 14 is a diagram showing a usage example of the holding device of FIG. 12 and the frame body of FIG. 13. In FIG. 12, only the contact member 51 of the holding device is shown, but other configurations are the same as those of the holding device described above.

[0085] As shown in FIG. 12, the contact member 51 may be provided with a movement restricting member 54. The movement restricting member 54 is provided at a position away from the contact portion 52. The shape of the movement restricting member 54 is arbitrary, but in this example, it is plate-shaped. The movement restricting member 54 is a plate-shaped member arranged in parallel with the contact portion 52.

[0086] As shown in FIG. 13, the frame body 20 may have a through hole 21h at a position corresponding to, for example, the position where the protruding portion 25 in FIG. 10 is provided. The through hole 21h extends in the thickness direction of the upper frame 21. A member 27, which is a member separate from the frame body 20, is inserted into the through hole 21h. The shape of the member 27 is arbitrary, but in this example, it is, for example, rod-shaped. The member 27 is removably inserted into the through hole 21h.

[0087] As shown in FIG. 14, when the member 27 is inserted into the through hole 21h of the upper frame 21, the portions protruding from both surfaces of the upper frame 21 function as protruding portions (see the protruding portion 25 in FIG. 10). Then, the contact member 51 of the holding device is attached to the upper frame 21 in which the member 27 is arranged in this way. In the case of the configuration as shown in FIG. 13, if there is nothing to restrict the movement of the member 27, the member 27 may fall off. However, the contact member 51 is provided with a movement restricting member 54, and in the holding state as shown in FIG. 14, the horizontal movement of the member 27 is restricted by the action of the movement restricting member 54. Therefore, it is possible to prevent the member 27 from accidentally falling off while the frame body 20 is being pulled up. Further, in the configurations as shown in FIGS. 13 and 14, since the member 27 can be removed after the assembled panel is moved, it is not necessary to previously form a protruding portion on the frame body 20, and the frame body 20 does not become bulky.

[0088] <Modification Example 5> Although a pair of contact members 51 are provided in the holding device, it is assumed that, for example, during the process of pulling up the holding device 50, the pair of contact members 51 may open due to unexpected factors. In order to prevent such a situation, a connecting member such as a hook for connecting the opposing contact members 51 to each other may be provided.

[0089] <An Example of Manufacturing an Assembled Panel> The prefabricated panel may be manufactured through the following steps. FIG. 15 is a diagram for explaining an example of manufacturing the prefabricated panel, showing a state where reinforcing bars are provided on a frame body. FIG. 16 shows a state where assembled materials are arranged on the frame body in the state of FIG. 15. FIG. 17 shows a state where the upper frame of the frame body is arranged. FIG. 18 shows a state where a reinforcing coating layer is provided.

[0090] In FIG. 15, as an example, a frame body 120' without an upper frame is depicted. The frame body 120' may be a concrete member formed at the construction site or may be precast concrete. For such a frame body 120', an operator first arranges reinforcing bars 141. The reinforcing bars 141 are rod-shaped reinforcing members. The reinforcing bars 141 are longer than the length in the height direction inside the frame body 120 (FIG. 17). In this example, the lower end of the reinforcing bar 141 is fixed to the lower frame of the frame body. The reinforcing bars 141 extend in the vertical direction.

[0091] Next, as shown in FIG. 16, the operator arranges assembled materials 11 inside the frame body 120'. As an example, the operator fills mortar between adjacent assembled materials 11. Note that the filling of mortar is not essential, and a plurality of assembled materials 11 may be arranged without filling mortar. At least one reinforcing bar 141 passes through the plurality of assembled materials 11 laminated in the vertical direction.

[0092] Next, as shown in FIG. 17, the operator attaches an upper frame 121 to the frame body 120'. In this example, the upper frame 121 is placed on the upper parts of the left and right side frames 123. Thereby, one closed frame body 120 is formed.

[0093] The upper frame 121 may be formed with a plurality of holes into which a plurality of reinforcing bars 141 are inserted. According to the configuration in which the upper ends of the plurality of reinforcing bars 141 enter the holes of the upper frame 121 in the state where the upper frame 121 is arranged as shown in FIG. 17, there is an advantage that the plurality of reinforcing bars 141 are stably fixed and the strength and rigidity of the prefabricated panel are improved.

[0094] Next, as shown in FIG. 18, the operator forms a reinforcing coating layer 130 on one or both sides of the built-up wall composed of a plurality of built-up members. In one form, it is preferable that the reinforcing coating layer 130 is formed so as to be in contact with both the built-up wall and the frame body 120 (that is, the reinforcing coating layer 130 is formed in a region extending from the built-up wall to the frame body 120). The material of the reinforcing coating layer 130 is the same as that of the above-described embodiment.

[0095] In the above description, an example of arranging the reinforcing bars 141 has been described, but the plurality of built-up members 11 may be stacked in the frame body without using the reinforcing bars 141. In this case, mortar may be filled between the built-up members 11 and / or between the built-up member 11 and the frame body 120. However, such mortar may not be used.

[0096] When using, for example, ready-made blocks whose height and width dimensions are set in advance to predetermined values as the built-up members, it is assumed that a gap will occur between the blocks arranged in the frame body and the frame body. The reason for this is, for example, in the width direction, the inner length of the frame body is not an integer multiple of the length of the block, and when a plurality of blocks are arranged, a gap of less than one block is generated between the end of the block and the inner side of the frame body. In such a case, this gap may be filled with mortar or the material of the reinforcing coating layer, or the amount of mortar filled between adjacent blocks may be increased to increase the joint dimension and adjust the width. Note that a filler such as a fiber material may be arranged between the blocks to adjust the gap, and the material of the reinforcing coating layer may be applied to this fiber material.

[0097] <An example of a building structure> FIG. 19 is a diagram showing an example of a building structure. The building structure in FIG. 19 includes a built-up panel S100 and a floor structure 80.

[0098] When installing the prefabricated panel S100, there is a risk that the prefabricated panel S100 may fall over. Therefore, in the configuration of Fig. 19, a member for supporting the prefabricated panel S100 is provided (details below). The floor structure 80 is, as an example, a slab floor. The floor structure 80 may be a portable member or a part of a building. A plurality of support members 85 are provided on the floor structure 80.

[0099] The support member 85 is provided so as to protrude from the upper surface (floor surface) of the floor material 81. The support member 85 is, as an example, a rod-shaped member. The support member 85 does not necessarily have to be integrally provided with the floor material 81 and may be inserted into a hole formed in the floor material 81.

[0100] As shown in Fig. 19, holes 101h into which the support members 85 can fit are formed in the lower surface of the prefabricated panel S100. The prefabricated panel S100 is installed on the upper surface of the floor structure 80 such that the support members 85 fit into the respective holes 101h. According to such a configuration, since the support members 85 fit into a part of the prefabricated panel S100 to support the prefabricated panel S100, the prefabricated panel S100 is prevented from falling over.

[0101] In Fig. 19, a state in which the support member 85 fits into the hole 101h is shown near the side portion of the prefabricated panel S100. However, as will be described later, when the support 90 is arranged at the corner of the floor structure 80, the support member 85 does not necessarily have to fit into the prefabricated panel S100 near the side portion of the prefabricated panel S100.

[0102] When manufacturing the above building structure, an operator performs the following steps, for example. First, the operator places a plurality of built-up members inside the frame and fixes the built-up wall composed of the plurality of built-up members and the frame to manufacture a built-up panel. Next, the operator places the built-up panel on the floor structure, and places the built-up panel so that a support member protruding upward from the floor structure is inserted into a part of the built-up panel. As a subsequent process, for example, a reinforcing coating layer may be formed in a region extending from the built-up panel to the floor structure, whereby the two members are fixed more firmly.

[0103] (Building structure with corners reinforced by support members) FIG. 20 is a diagram showing another example of a building structure. FIG. 21 is a perspective view of the floor structure. FIG. 22 is a diagram showing a state in which a support is attached to the floor structure. FIG. 23 is a diagram showing a state in which a built-up panel is attached to the structure in the state of FIG. 22.

[0104] The building structure S200 includes a built-up panel S100, a floor structure 80, and a support 90. Although the built-up panel is indicated by the reference numeral S100, as long as it is a built-up panel according to the present invention, the built-up panel is not necessarily limited to the built-up panel S100 shown in FIGS. 1 and 2 and the like. A reinforcing coating layer may be formed on one side of the built-up panel S100, or a reinforcing coating layer may be formed on both sides of the built-up panel S100.

[0105] The floor structure 80 has a floor material 81 (FIG. 21). The floor material 81 is, for example, quadrilateral. On the upper surface of the floor material 81, the built-up panel S100 is arranged along the sides of the floor material 81.

[0106] The support member 90 is a member disposed at the corner of the floor structure 80. Since the support members 90 disposed at each corner have the same structure as each other, the structure of one corner will be described below. As an example, the support member 90 is a member having an L-shaped cross-sectional shape in the horizontal direction. As can be understood by looking at the support member 90-1 in FIG. 20, the support member 90 supports the first built-up panel S100-1 and the second built-up panel S100-2 in contact with both panels at the portion where the first built-up panel S100-1 and the second built-up panel S100-2 are adjacent to each other. Specifically, a reinforcing coating layer may be formed in the region extending from the first built-up panel S100-1 to the support member 90, so that the first built-up panel S100-1 and the support member 90 may be fixed to each other. For example, the first built-up panel S100-1 and the support member 90 may be fixed to each other by mortar filled between the first built-up panel S100-1 and the support member 90. The same applies to the second built-up panel S100-2 and the support member 90.

[0107] According to the configuration in which the support members 90 that support the adjacent built-up panels are provided in this way, the structure can be reinforced well. That is, at the location where the panels intersect, stress concentration is likely to occur. Therefore, by providing the support member 90 as in this embodiment, damage at the corner of the building structure S200 is less likely to occur.

[0108] The support member 90 may be pre-manufactured and transported to the construction site. By using such a support member 90, it is possible to prevent variations in quality due to the skill level of the workers at the construction site, and homogenization can be achieved. The pre-formed support member 90 may have a hole formed in the lower surface into which the support column member 85 is inserted. The support member 90 may also be formed at the construction site, for example, by pouring concrete into a formwork.

[0109] (Manufacture of Building Structure S200) The building structure S200 may be manufactured in the following steps. In the following, an example is given in which a plurality of support members 85 are used, but it is not essential to use a plurality of support members 85 in the present invention.

[0110] First, the operator attaches a plurality of support members 85 to the floor structure 80 (FIG. 21). Next, the operator places the support 90 at the corner of the floor structure 80 (FIG. 22).

[0111] Thereafter, the operator places the prefabricated panel S100 on the floor structure 80. Specifically, as an example, the operator places the first prefabricated panel S100-1 so as to extend in the first direction (the long side direction of the floor structure 80). Also, the operator places the second prefabricated panel S100-2 so as to extend in the second direction (the short side direction). Similarly, the prefabricated panel S100 is placed on the remaining two sides as well.

[0112] Next, at the position (corner) where the first prefabricated panel S100-1 and the second prefabricated panel S100-2 are adjacent, the operator fixes the first prefabricated panel S100-1 and the second prefabricated panel S100-2 to the support 90. The fixing may be, for example, fixing with mortar as described above, fixing with a reinforcing coating layer, or fixing by a combination thereof.

[0113] As an example of the work of fixing by a reinforcing coating, the operator may form a reinforcing coating layer in a region extending from the first prefabricated panel S100 to a part of the support 90, and form a reinforcing coating layer in a region extending from the second prefabricated panel S100-2 to another part of the support 90. Of course, on both sides of the prefabricated panel S100, the prefabricated panel S100 and the support 90 may be fixed by a reinforcing coating layer.

[0114] (Modification example of building structure) FIG. 24 is a view showing another example of a building structure. FIG. 25 is a view showing a floor structure and a support. The building structure S201 includes a floor structure 80 and a support 90'. The building structure S201, like the building structure S200, also includes prefabricated panels, but illustration thereof is omitted in FIG. 24.

[0115] In the support 90', a column portion 93 (FIG. 25) extending vertically is formed thinner than that of the support 90. At the upper part of the column portion 93, a first laterally extending portion 91a and a second laterally extending portion 91b are provided. Similarly, at the lower part of the column portion 93, a first laterally extending portion 92a and a second laterally extending portion 92b are provided.

[0116] The first laterally extending portion 91a and the second laterally extending portion 91b extend in directions orthogonal to each other as an example. The first laterally extending portion 92a and the second laterally extending portion 92b have the same configuration. The horizontal protruding length of the first laterally extending portion 91a from the column portion 93 is, for example, the same as or substantially the same as the horizontal length of the prefabricated material 11. The second laterally extending portion 91b has the same configuration. Since the support 90' has a column portion 93 formed thinner than that of the support 90, it is advantageous for weight reduction and cost reduction of the member as compared with the support 90.

[0117] As shown in FIG. 24, a plurality of prefabricated materials 11 may be laminated in the vertical direction along the first laterally extending portion 91a and the second laterally extending portion 91b. The plurality of laminated prefabricated materials 11 may be fixed to each other by, for example, mortar or the like. The plurality of prefabricated materials 11 may also be fixed to the support 90' by, for example, mortar or the like or a reinforcing coating layer.

[0118] The prefabricated panel is arranged so as to be sandwiched between one support 90' and the other support 90' where a plurality of prefabricated materials 11 are arranged. By fixing the prefabricated panel, each support 90', and the prefabricated material 11, a building structure with improved strength and rigidity can be manufactured. The fixing of the prefabricated panel, the support 90', and the prefabricated material 11 may be realized by mortar or a reinforcing coating layer.

[0119] As described above, the present invention has been described using embodiments. However, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist. For example, although the example in which the assembled wall is manufactured inside the frame has been described above, the use of the frame is not essential. For example, a construction method may include a step of arranging a plurality of assembled members to manufacture an assembled wall composed of the plurality of assembled members, a step of forming a reinforcing coating layer on the wall surface of the assembled wall, and a step of moving the assembled wall to a predetermined position.

[0120] The assembled wall may be manufactured without using a frame, a reinforcing coating layer may be formed on the wall surface thereof, and then the assembled wall (assembled wall having a reinforcing coating layer) may be stored or moved in a flat state. When storing or moving a plurality of assembled walls (which may be assembled panels), they may be stacked flat directly or with a protective material (such as a sheet or a plate) interposed therebetween.

[0121] In this specification, for example, all or part of the device can be configured to be functionally or physically dispersed and integrated in any unit. Also, new embodiments resulting from any combination of a plurality of embodiments are included in the embodiments of the present invention. The effects of the new embodiments resulting from the combination have the effects of the original embodiments combined.
