[0001] The present invention relates to a fastening device used in the construction of a compound wall and a method for constructing a compound wall using the fastening device. [Background technology]

[0002] A conventional construction method using formwork is described, for example, in Patent Document 1. This conventional construction method includes the steps of providing a support frame layer composed of reinforcing bars for the wall, placing formwork on two sides of the support frame layer, pouring a material to be hardened into the support frame layer, and removing the formwork from the support frame layer to obtain the wall. To obtain a composite wall, the conventional construction method further includes the steps of measuring the wall and marking drilling positions, drilling holes in the wall at the drilling positions and inserting plugs, installing a first vertically extending metal frame using screws attached to the plugs, placing insulation on the first metal frame, drilling holes in the insulation and securing the insulation to the wall via fasteners, and installing a second horizontally extending metal frame and installing a ceramic or metal plate. In other words, conventional composite wall construction methods require multiple measuring and drilling steps, which are time-consuming and labor-intensive. [Prior art documents] [Patent documents]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] In order to more clearly describe the objectives, technical means, and advantages of the embodiments of the present invention, the following will clearly and in detail describe the technical means in the embodiments of the present invention in combination with the accompanying drawings of the embodiments of the present invention. It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. Generally, the components of the embodiments of the present invention depicted and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present invention provided below in the accompanying drawings does not constitute any limitation on the protection scope of the present invention, but merely represents selected embodiments of the present invention.

[0011] Before describing the present invention in detail, it should be noted that in the following description, elements that perform the same role or function are designated by the same numerals even if they do not have exactly the same configuration.

[0012] FIG. 1 is a flowchart showing a first embodiment of the compound wall construction method of the present invention. As shown in the figure, the compound wall construction method of the present invention includes first to seventh steps.

[0013] First, in the first step S1, a support frame layer 1 having a first surface side and a second surface side is prepared as shown in Figure 2. The support frame layer 1 is, for example, a framework made up of multiple reinforcing bars and built at the site where the columns and walls of the building are to be constructed.

[0014] 3 shows a first embodiment of the fixing device 4 of the present invention, and as shown in the figure, this fixing device 4 has a main rod 41. In the second step S2, a plurality of these fixing devices 4 are used to penetrate the first insulation layer 2A and the first framework 3 to fix the first insulation layer 2A to the first framework 3, as shown in Fig. 2. At this time, the main rods 41 of each fixing device 4 all penetrate the first insulation layer 2A and the first framework 3, and the main rods 41 have tip portions 411 that pass through the first framework 3.

[0015] Further, to explain the first embodiment of the fixing device 4 of the present invention in more detail, the fixing device 4 comprises a main rod 41, a housing 42, a positioning means 43, and a partition plate 44. The main rod 41 is formed into a rod-like body extending from a head portion 412 to a tip portion 411, the housing 42 is attached to the main rod 41 so as to shield the head portion 412, the partition plate 44 is fixed to the housing 42, and the positioning means 43 is attached so as to be movably and detachably fitted onto the tip portion 411 relative to the main rod 41.

[0016] Furthermore, in this first embodiment, a male thread is formed on the tip portion 411, and the tip of the head portion 412 is formed in a hexagonal bipyramid shape.

[0017] The housing 42 is made of a heat insulating material such as resin, and is attached to the main rod 41 so as to shield the head portion 412. In the following description, the portion of the main rod 41 that is not shielded by the housing 42 corresponds to the tip portion 411. The partition plate 44 is formed on the housing 42, and in this first embodiment, is formed in a disk shape at the end of the housing 42 that faces the tip portion 411.

[0018] The positioning means 43 has a positioning member 431 movably and removably attached to the main rod 41 so as to be fitted onto the tip end portion 411, and a retaining abutment 432 detachably attached to the main rod 41 so as to be fitted onto the tip end portion 411 at a position closer to the housing 42 than the positioning member 431. In this embodiment, the positioning member 431 is a nut, and the retaining abutment 432 is formed into a disk.

[0019] That is, in the second step S2, each fixing device 4 is attached to the first insulation layer 2A and the first framework 3 as follows: First, with the positioning member 431 and the retaining backing member 432 of the positioning means 43 removed, the main rod 41 of the fixing device 4 is inserted from the tip 411 through the first insulation layer 2A and the first framework 3 in order until the partition plate 44 abuts against the first insulation layer 2A, and at this time, the housing 42 is inserted into the first insulation layer 2A, and the tip 411 exposed outside the housing 42 is inserted through the first framework 3. Then, the positioning member 431 is attached to the exposed part of the tip 411 inserted through the first framework 3, so that the first insulation layer 2A and the first framework 3 are connected and fixed together.

[0020] The first insulating layer 2A can be made of any one material selected from, for example, expanded polystyrene (EPS), polyisocyanurate (PIR), graphite polystyrene (GPS), and rigid insulating material.

[0021] In the third step S3, the first framework 3 is placed on the first surface of the support frame layer 1 so that the first insulation layer 2A faces the support frame layer 1, and the second framework 5 is placed on the opposite side of the first framework 3, i.e., the second surface of the support frame layer 1. At this time, the partition plate 44 abuts against the first insulation layer 2A, so that the head portions 412 shielded by the housings 42 of each fixing device 4 are positioned within the support frame layer 1, which is a framework made of, for example, steel bars.

[0022] As shown in Figure 4, in the fourth step S4, a hardening material, such as concrete, is injected into the support frame layer 1 and allowed to harden, thereby fixing the first insulation layer 2A to the support frame layer 1 and each fixing device 4.

[0023] In the fifth step S5, as shown in Figures 4 and 5, the second framework 5 and the first framework 3 are removed from the support frame layer 1, so that the tip portions 411 of the main rods 41 of each fixing device 4 are exposed outside the first insulation layer 2A.

[0024] That is, first, the positioning members 431 of each fixing device 4 are removed, then the first framework 3 is also removed to expose the first insulating layer 2A, and then each holding backing member 432 is fitted onto each fixing device 4 until it abuts against the first insulating layer 2A. In this way, the first insulating layer 2A is held and fixed by the positioning means 43 (holding backing member 432). Incidentally, in this embodiment, a male thread is formed on the tip portion 411, and the holding backing member 432 is attached by screwing into the male thread formed on the tip portion 411, so that the thickness of the first insulating layer 2A can be appropriately set as needed.

[0025] 6, in a sixth step S6, a plurality of external brackets 6 (only one is shown in the figure because it is a cross-sectional view) are attached to the tip portion 411 of the main rod 41 of each fixing device 4 that is exposed outside the first insulation layer 2A, and then in a seventh step S7, a plurality of first shielding plates 7 (only one is shown in the figure because it is a cross-sectional view) are attached to the surfaces of the plurality of external brackets 6 that do not face the first insulation layer 2A, thereby completing the composite wall construction method of the present invention. The first shielding plates 7 can be made of, for example, ceramic, but can also be made of other materials such as stone, metal, or brick.

[0026] Figures 7 to 10 show a modified example of the method for constructing a composite wall of the present invention in which a second embodiment of the fixing device of the present invention is used, and Figure 8 is a perspective view showing the configuration of the second embodiment of the fixing device of the present invention.

[0027] First, a second embodiment of the fixing device of the present invention shown in Figures 7 and 8 differs from the first embodiment (see Figure 3) in the configuration of positioning means 43. In this second embodiment, positioning means 43 has a positioning stopper member 433 instead of positioning member 431 and retaining backing member 432 (see Figure 3). This positioning stopper member 433 has a plate-shaped portion 433b and a sleeve portion 433a that extends in a tubular shape from plate portion 433b so as to be perpendicular to plate portion 433b and is attached so as to be movably and removably fitted onto tip portion 411 of main rod 41. The sleeve portion 433a is configured to be able to thread onto a male thread formed on tip portion 411 of main rod 41, and is attached so as to be movably and removably fitted onto tip portion 411 of main rod 41. Furthermore, a hexagonal columnar recess 433c is formed at a location on the end face of the plate-shaped portion 433b away from the partition plate 44 that corresponds to the extension direction of the main rod 41, so that the engagement relationship between the stopper member 433 and the tip portion 411 of the main rod 41 can be adjusted by inserting a corresponding tool (e.g., a hexagonal wrench) into the hexagonal columnar recess 433c and rotating the stopper member 433.

[0028] In the second step S2 of the composite wall construction method of the present invention, with the stopper member 433 of the positioning means 43 removed, the main rod 41 of each fixing device 4 is inserted from its tip 411 through the second insulation layer 2B and the second framework 5 in order until the partition plate 44 abuts against the second insulation layer 2B, and at this time, the housing 42 is inserted into the second insulation layer 2B, and the tip 411 exposed outside the housing 42 is inserted through the second framework 5. Then, the stopper member 433 is attached to the part of the tip 411 exposed after inserting through the second framework 5 until the plate-shaped portion 433b of the stopper member 433 abuts against the front side of the second framework 5 (the left side in the figure), thereby connecting and fixing the second insulation layer 2B and the second framework 5 together.

[0029] Incidentally, the second insulating layer 2B can be made of any one of the materials selected from expanded polystyrene (EPS), polyisocyanurate (PIR), graphite polystyrene (GPS), and rigid insulating material, just like the first insulating layer 2A.

[0030] In the third step S3, the first framework 3 is placed on the first surface of the support frame layer 1 so that the first insulation layer 2A (not shown) faces the support frame layer 1, and the second framework 5 is placed on the opposite side of the first framework 3, i.e., the second surface of the support frame layer 1, so that the second insulation layer 2B faces the support frame layer 1. In other words, the support frame layer 1 is sandwiched between the first insulation layer 2A and the second insulation layer 2B, and the partition plate 44 is sandwiched between the second insulation layer 2B and the support frame layer 1 so as to abut against the second insulation layer 2B, so that the head portion 412 shielded by the housing 42 of each fixing device 4 is located within the support frame layer 1, which is a framework made of, for example, steel bars.

[0031] In the fourth step S4, a hardening material, such as concrete, is injected into the support frame layer 1 and allowed to harden, thereby fixing the first insulation layer 2A and the second insulation layer 2B to the support frame layer 1 and each fixing device 4.

[0032] In the fifth step S5, first, the stopper members 433 of the positioning means 43 of each fixing device 4 are removed from the tip portions 411 of the main rods 41, then the first framework 3 and the second framework 5 are also removed to expose the first insulating layer 2A and the second insulating layer 2B, and then the stopper members 433 of the positioning means 43 are attached to the tip portions 411 of the main rods 41 until the plate-shaped portions 433b abut against the second insulating layer 2B to hold and fix the second insulating layer 2B. At this time, it is preferable that recesses corresponding to the size of the plate-shaped portions 433b for accommodating the plate-shaped portions 433b are formed in advance in the second insulating layer 2B.

[0033] In a sixth step S6 and a seventh step S7, the second shielding plate 8 is attached to the second insulating layer 2B using, for example, adhesive or screws. The second shielding plate 8 can be, for example, a calcium silicate board or a gypsum board.

[0034] In this embodiment, the positioning stopper member 433, which is composed of the sleeve portion 433a and the plate-like portion 433b, may be made integrally, or may be made as separate members and then joined together.

[0035] It is also possible to connect the second insulating layer 2B to the second framework 5 using the fastening device 4 of the first embodiment shown in FIG.

[0036] Figures 11 to 15 show a modified example of the method for constructing a composite wall of the present invention in which a third embodiment of the fixing device of the present invention is used, and Figure 12 is a perspective view showing the configuration of the third embodiment of the fixing device of the present invention.

[0037] As shown, the third embodiment of the fixing device of the present invention differs from the first embodiment (see FIG. 3) in the configuration of the positioning means 43 and the partition plate 44. In this third embodiment, the positioning means 43 has a positioning member 431 and a retaining pad member 432.

[0038] The positioning member 431 is formed to have a columnar portion 431a and a support plate portion 431b that extends outward from the end of the columnar portion 431a facing the holding backing member 432, and the width of the support plate portion 431b that extends from the columnar portion 431a is formed so that the side closer to the holding backing member 432 is larger than the side away from the holding backing member 432.

[0039] The retaining backing member 432 is formed in a circular dish shape, and the radius of the retaining backing member 432 is formed so that the side closer to the tip 411 is larger than the side farther from the tip 411 .

[0040] The partition plate 44 is formed in the shape of a circular dish that protrudes outward from the housing 42, and the width of the protrusion from the housing 42 is formed so that the side closer to the tip 411 is larger than the side away from the tip 411.

[0041] As described above, the third embodiment of the fixing device of the present invention has the same positioning member 431 and retaining backing member 432 as the first embodiment, and can therefore be applied to the construction method of a compound wall in the same manner as the first embodiment. In this third embodiment, the support plate portion 431b of the positioning member 431, the retaining backing member 432, and the partition plate 44 are all formed in a circular dish shape, and the side facing the object to be abutted is wider, so that a more effective holding / fixing effect can be expected than in the first embodiment.

[0042] Furthermore, Figure 16 is a perspective view showing the configuration of a fourth embodiment of the fixing device of the present invention, and Figure 17 is an explanatory cross-sectional view showing a modified example of the construction method of the composite wall of the present invention in which the fourth embodiment of the fixing device of the present invention is used.

[0043] As shown in the figure, the fourth embodiment of the fixing device of the present invention differs from the third embodiment (see FIG. 12) in the shape of the supporting backing 432. In this fourth embodiment, the supporting backing 432 is formed in a circular dish shape, and the radius of the supporting backing 432 increases in a stepped manner from the side away from the tip 411 to the side closer to the tip 411. As shown in FIG. 17, the fourth embodiment of the fixing device of the present invention can be applied to the construction method of a composite wall in the same manner as the first and third embodiments, and since the shape of the supporting backing 432 increases in a stepped manner from the side away from the tip 411 to the side closer to the tip 411, it is expected that the connection effect with the first insulation layer 2A will be improved.

[0044] To summarize the above, in any embodiment of the fixing device 4 of the present invention, the fixing device 4 can be attached to the support frame layer 1 before the material to be hardened is injected, with the first insulation layer 2A connected to the first framework 3 and the second insulation layer 2B connected to the second framework 5. After the material to be hardened is injected and hardened, the fixing device 4 is fixed to the support frame layer 1, and the first insulation layer 2A or the second insulation layer 2B is held by the fixing device 4 and connected to the support frame layer 1. Therefore, the first framework 3 or the second framework 5 can be removed and a first shielding plate 7 or a second shielding plate 8 can be attached to further enhance the functionality of the composite wall, such as insulation.

[0045] Therefore, the composite wall construction method implemented by using the fixing device 4 of the present invention can reduce the number of steps and shorten the construction period, and further eliminates the steps required for bonding and polishing the first insulation layer 2A and the second insulation layer 2B, and the labor required for drilling holes for installation in the first insulation layer 2A and the second insulation layer 2B. It also reduces waste generated during construction. In this way, the present invention can reduce the construction period and construction costs.

[0046] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
