Description

[Technical field]

[0001] The present invention relates to a mounting hardware for aerated lightweight concrete panels (ALC panels). More specifically, the present invention relates to a mounting hardware for constructing a locking mechanism for aerated lightweight concrete panels, which can provide an appropriate locking mechanism to a wall (ALC panel wall) constructed using ALC panels, and a mounting structure for aerated lightweight concrete panels using the same. [Background technology]

[0002] Conventionally, the exterior walls of buildings have been widely constructed using ALC panels. In such ALC panel walls, the weight of the ALC panels is supported by mounting hardware attached to the building frame via steel base materials such as angles.

[0003] Here, when a certain level of external force is applied to a wall made of ALC panels (ALC panel wall), the stress generated at the panel mounting portion exceeds the allowable stress level, and there is a risk that the ALC panel may fall off or be locally destroyed. To avoid this, ALC panel walls are usually provided with a locking mechanism that can release the above-mentioned stress by slightly rotating the ALC panel in the direction of the wall surface. As a metal fitting for providing such a locking mechanism, a metal fitting that is placed between the bottom surface of the ALC panel and the mounting metal fitting and has a protrusion formed thereon to ensure the clearance required to realize the locking performance is widely used (Patent Document 1).

[0004] However, even with the mounting structure described in Patent Document 1, in order to achieve appropriate locking performance in the ALC panel wall, it was necessary to fasten the metal fittings for ensuring the above-mentioned clearance one by one with high positional accuracy to the bottom surface of the ALC panel facing the weight support metal fittings. Fastening the metal fittings for ensuring this clearance is often done manually by the builder at the building site, and there was a demand for improvements in terms of the variation in quality depending on the builder and the complexity of the work.

[0005] In response to such demands for improvement, an integrated mounting hardware has been proposed, which has a structure in which two fittings corresponding to the fitting for constituting the locking mechanism and the weight-receiving fitting in the conventional mounting structure for ALC panels are joined together as an integrated unit consisting of a weight-receiving fitting and a panel mounting fitting having a unique shape (see Patent Document 2). This integrated mounting hardware eliminates the need for the process of fastening the fitting for constituting the locking mechanism to the bottom surface of the panel in the conventional structure, suppressing the above-mentioned quality variations and also improving the workability of the ALC panel mounting work.

[0006] However, in order to obtain the integrated mounting hardware described in Patent Document 1, the two hardware pieces need to be molded into a unique shape (a special shape having claws and through slits) that is significantly different from general-purpose products, which poses the problem of increased manufacturing costs. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2006-16841 A [Patent Document 2] JP 2017-166276 A Summary of the Invention [Problem to be solved by the invention]

[0008] The object of the present invention is to make it possible to easily install ALC panel walls equipped with a locking mechanism in a simplified procedure using hardware that is not significantly different in shape from conventional general hardware and can be manufactured at low cost. [Means for solving the problem]

[0009] The inventors discovered that the above problems could be solved by a mounting hardware in which two metal fittings are integrated via a connecting metal fitting having a simple shape, and thus completed the present invention. Specifically, the present invention provides the following.

[0010] (1) A mounting hardware for a lightweight aerated concrete panel, comprising: a weight-bearing bracket having a substantially rectangular weight-bearing horizontal plate and a vertical support plate rising perpendicularly from one side of the weight-bearing horizontal plate; a panel mounting bracket consisting of a substantially rectangular panel mounting plate placed on the weight-bearing surface of the weight-bearing horizontal plate; and a band- or rod-shaped connecting hardware that joins the weight-bearing bracket and the panel mounting bracket. The connecting hardware is connected to the surface of the panel mounting plate facing the weight-bearing horizontal plate or to the surface of the weight-bearing horizontal plate facing the weight-bearing horizontal plate. A mounting hardware for lightweight aerated concrete panels, in which a protrusion for constituting a locking mechanism is formed on one of the faces facing the panel mounting plate, and a joint through hole is formed in the weight-supporting horizontal plate and the panel mounting plate, the joint through hole passing through the top of the protrusion, and the weight-supporting fitting and the panel mounting fitting are swingably joined by the connecting fitting inserted into the joint through hole.

[0011] (1) The mounting hardware for lightweight aerated concrete panels enables the panel mounting work in the construction of an ALC panel wall equipped with a locking mechanism to be easily performed in a simplified procedure using hardware that has a shape that differs little from that of conventional general hardware and can be manufactured at low cost, thereby improving the quality stability and productivity of the ALC panel wall.

[0012] (2) A mounting hardware for lightweight aerated concrete panels as described in (1), wherein the connecting fitting is a band-shaped fitting and the horizontal cross-sectional shape of the joint through hole is an ellipse having a minor axis shorter than the width of the connecting fitting, or the horizontal cross-sectional shape is a rectangular slit having a gap width shorter than the width of the connecting fitting.

[0013] (2) The mounting hardware for lightweight aerated concrete panels can suppress unnecessary rotation of the connecting hardware inside the joint through-hole. This reliably prevents the panel mounting hardware from rotating unnecessarily after the mounting hardware is attached to the building frame and before or during the installation of the ALC panel, causing interference with the welded bead of the weight-bearing hardware (e.g., welded bead 40 in Fig. 6), which causes the panel mounting hardware to lose its inclination and prevents the locking function from being fully exerted.

[0014] (3) The connecting fitting is an attachment fitting for a lightweight aerated concrete panel described in (2), having a U-shaped locking portion formed by bending the end portion on the weight-bearing horizontal plate side so that it is in close contact with the bottom surface, the front end surface, and the top surface of the weight-bearing horizontal plate side, and / or a V-shaped locking portion formed by folding back the end portion on the panel mounting plate side.

[0015] (3) According to the mounting hardware for lightweight aerated concrete panels, the hardware has a simple structure and can stably connect the weight-supporting hardware and the panel mounting hardware to each other while preventing unnecessary rotation of the panel mounting hardware.

[0016] (4) A mounting structure for a lightweight aerated concrete panel, in which a lightweight aerated concrete panel is placed on the panel mounting plate of a mounting bracket for a lightweight aerated concrete panel described in any one of (1) to (3).

[0017] According to the mounting structure for the lightweight aerated concrete panel of (4), by enjoying the above-mentioned effects of the mounting hardware for the lightweight aerated concrete panel described in any of (1) to (3), the panel mounting work in the construction of an ALC panel wall having a locking mechanism can be easily performed with a procedure that is simpler than before, thereby improving the quality stability and productivity of the ALC panel wall.

[0018] (5) A lightweight aerated concrete panel wall, in which the lightweight aerated concrete panel is attached to a building structure by the mounting structure for the lightweight aerated concrete panel described in (4).

[0019] According to the invention of (5), for example, in a wall structure formed by stacking a large number of lightweight aerated concrete panels horizontally, the above-mentioned effects of the mounting structure for the lightweight aerated concrete panels described in (4) can be enjoyed. This makes it possible to improve the economy and quality stability of the ALC panel wall structure equipped with a locking mechanism. Effect of the Invention

[0020] According to the present invention, the installation work of an ALC panel wall equipped with a locking mechanism can be easily carried out in a simplified procedure using hardware that is not significantly different in shape from conventional general hardware and can be manufactured at low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, preferred embodiments of the "attachment hardware for lightweight aerated concrete panels (hereinafter, also simply referred to as "attachment hardware")" of the present invention, the "attachment structure for lightweight aerated concrete panels (hereinafter, also simply referred to as "attachment structure")" of the present invention, and the "lightweight aerated concrete panel wall (hereinafter, also simply referred to as "wall")" of the present invention will be described. In the following, an embodiment in which the present invention is applied to a lightweight aerated concrete panel wall in which a plurality of rectangular ALC panels are stacked horizontally and both ends of the panels are joined to a building frame such as a pillar of a building to form a curtain wall of a building will be described. However, the present invention is not limited to the above embodiment. The present invention can be widely applied to a general wall having a locking mechanism formed by ensuring a predetermined clearance between the weight-receiving hardware and the bottom surface of the precast panel that forms the curtain wall of a building.

[0023] <Lightweight aerated concrete panel wall> 8 is an elevational view of a wall 200 of the present invention in which an ALC panel is attached to a building framework 50 by a mounting structure 100 using the mounting hardware 10 of the present invention. The wall 200 is provided with a locking mechanism. This locking mechanism is mainly ensured by the mounting structure 100. The mounting structure 100 is a joint structure between the mounting hardware 10 and the ALC panel 20, which is formed at the portion where the ALC panel 20 is placed on the mounting hardware 10.

[0024] As shown in Figure 8, a wall 200 has a number of rectangular ALC panels 20 stacked horizontally. The weight of the ALC panels 20 is supported primarily by mounting hardware 10 installed at intervals of every few panels along the vertical direction of the wall 200. The mounting hardware 10 is fixed to the building framework 50 via foundation steel 30 made of vertical angles. The mounting hardware 10 is positioned at positions corresponding to both ends in the width direction of the lower end face of the ALC panel 20, thereby effectively supporting the weight of the ALC panel 20.

[0025] <Installation structure for lightweight aerated concrete panels> In the mounting structure 100, which is a joint structure between the mounting hardware 10 and the ALC panel 20, the ALC panel 20 is mounted to the mounting hardware 10 in a manner that allows it to exhibit locking performance, as shown in Fig. 7. More specifically, the mounting structure 100 constitutes a locking mechanism in the wall body 200 by appropriately forming the protrusions (hereinafter also simply referred to as "protrusions") 22 for configuring the locking mechanism of the mounting hardware 10, and this ensures the locking performance of the wall body 200.

[0026] <Fitting hardware for lightweight aerated concrete panels> 1, 2, and 3, the mounting hardware 10 is an integrated mounting hardware configured by connecting a weight-bearing bracket 1 and a panel mounting bracket 2 in a "swingable" manner via a connecting bracket 3. In this specification, a "swingable" joint structure means that, when a wall body 200 is configured with a mounting structure 100 including the mounting hardware 10, the panel mounting bracket 2 of the mounting hardware 10 swings relative to the weight-bearing bracket 1 within a range required to realize the rocking performance of the wall body 200, that is, the performance of releasing stress caused by external forces by minute rotation of the ALC panel 20, as described above, and more specifically, the structure is capable of rotating the ALC panel 20 within a required minute range within the wall surface direction of the wall body 200.

[0027] [Self-weight support bracket] The weight support fitting 1 is a metal member including a substantially rectangular weight support horizontal plate 11 and a substantially rectangular vertical support plate 12 that rises vertically from one side of the weight support horizontal plate 11 relative to the weight support horizontal plate 11. The weight support fitting 1 can be formed to include each of the above-mentioned parts, for example, by bending vertically at predetermined positions a single metal plate punched into a predetermined shape.

[0028] 1, 2, and 3, the weight support fitting 1 has a joint through hole 4 through which the connecting fitting 3 is inserted, formed in a portion that is to be the contact point with the protrusion 22 of the weight support horizontal plate 11. The position at which the joint through hole 4 is formed in the weight support horizontal plate 11 may be the center position in the lateral direction (direction parallel to the bending side) of the weight support horizontal plate 11 (see Figs. 1 and 3), and may be any position (see Fig. 2) that is the center in the depth direction or closer to the tip of the weight support horizontal plate 11 where the protrusion 22 can be stably placed.

[0029] [Panel mounting bracket] The panel mounting bracket 2 is a metal member constituted by a substantially rectangular panel mounting plate 21. A protrusion 22 for forming a locking mechanism is formed in the center of the surface of the panel mounting plate 21 facing the weight-receiving horizontal plate 11, which contributes to the construction of the locking mechanism by making point contact with the opposing surface. In the mounting hardware 10 shown in Figures 1, 2, and 3, the protrusion 22 is formed with its top pointing downward on the surface of the panel mounting plate 21 constituting the panel mounting bracket 2 facing the weight-receiving horizontal plate 11.

[0030] However, the mounting hardware for lightweight aerated concrete panels of the present invention can also be configured to form a protrusion with its top pointing upward on the upper surface (the surface facing the panel mounting plate 21) of the weight-supporting horizontal plate 11 of the weight-supporting hardware 1, and to form a locking mechanism (not shown) that exerts the same effect as described above by bringing the thus-formed protrusion into point contact with the opposing surface (the back surface of the panel mounting plate 21). In this case, the position at which the joint through hole 4 is formed in the weight-supporting horizontal plate 11 may be a position that passes through the apex of the protrusion 22.

[0031] In any of the above-mentioned embodiments, the shape of the protrusions 22 may be a convex shape that makes point contact with the surface facing each other, and is preferably a hemispherical shape. The height of the protrusions 22 is set to a predetermined size such that the clearance C shown in FIG. 2, that is, the clearance C between the weight-receiving horizontal plate 11 that is in point contact with the protrusions 22 and the panel mounting plate 21, can be swung in the above-mentioned manner and can exhibit rocking performance. Specifically, when the present invention is applied to a wall body 200 in which ALC panels 20 of 0.6 m x 6.0 m are stacked horizontally as shown in FIG. 8, this clearance C may be about 1 mm or more and 5 mm or less. For example, in a wall body 200 in which ALC panels 20 of the above-mentioned size are stacked horizontally, by installing the mounting hardware 10 with the clearance C, that is, the height of the protrusions 22 set to 3 mm, the inclination of the panel mounting plate 21 in the wall surface direction relative to the weight-receiving horizontal plate 11 can be allowed to be up to 4.5°, thereby exhibiting an appropriate rocking function.

[0032] 1, 2, and 3, the panel mounting fitting 2 is also formed with a joint through hole 4 for inserting the connecting fitting 3, similar to the weight-bearing fitting 1. The position at which the joint through hole 4 is formed in the panel mounting fitting 2 may be the center position of the panel mounting plate 21, at a position passing through the apex of the protrusion 22.

[0033] [Connecting fittings] The connecting fitting 3 is a belt-like or rod-like metal member that connects the weight support fitting 1 and the panel mounting fitting 2 in a "swingable" manner. FIG. 4 shows a belt-like connecting fitting 3 as an example of a connecting fitting according to the present invention. As shown in FIG. 4, the connecting fitting 3 is preferably configured with locking parts at both ends for stably maintaining the connection state between the weight support fitting 1 and the panel mounting fitting 2. The locking parts are not limited to a specific shape or structure as long as they can function to connect the weight support fitting 1 and the panel mounting fitting 2 in a "swingable" manner. Specific examples of preferred locking parts include a U-shaped locking part 31 and a V-shaped locking part 32 as shown in FIG. 4.

[0034] The U-shaped locking portion 31 is a locking portion formed in a portion near one end of the connecting fitting 3, and is a structural portion formed by folding back the end of the connecting fitting 3 on the weight-supporting horizontal plate 11 side into a U-shape as shown in Fig. 4. The U-shaped locking portion 31 is bent in such a manner that this portion is in close contact with the bottom surface on the weight-supporting horizontal plate 11 side, the small end surface on the front side, and the top surface, so that the above-mentioned joint state can be stably maintained (see Figs. 2 and 7).

[0035] V-shaped locking portion 32 is a locking portion formed on the other end of connecting fitting 3, and is a structural portion formed by folding back the end of connecting fitting 3 on the panel mounting plate 21 side into a V shape as shown in Fig. 4. With V-shaped locking portion 32, this portion is pressed against the inner circumferential surface of joint through-hole 4 by the elasticity of the band-shaped metal member, so that the above-mentioned joint state can be stably maintained (see Figs. 2 and 7).

[0036] Furthermore, the connecting fitting constituting the mounting hardware of the present invention may be a rod-shaped member with locking portions at both ends. Such a rod-shaped connecting fitting may be, for example, a spring member having an appropriate axis and elasticity relative to the inner diameter of the joint through hole 4. By configuring the weight support fitting 1 and the panel mounting fitting 2 to be "swingably" joined together while a connecting fitting made of such a spring member is inserted into the joint through hole 4, the weight support fitting 1 and the panel mounting fitting 2 can be "swingably" joined together while suppressing unnecessary rotation of the panel mounting fitting 2 by the elastic force of the spring member.

[0037] The shape and configuration of the connecting metal fittings for joining and integrating the weight-receiving metal fitting 1 and the panel mounting metal fitting 2 are not limited to the above-mentioned examples. As long as the connecting metal fittings have a shape and configuration that suppresses unnecessary rotation of the panel mounting metal fitting 2 while not impeding the above-mentioned "swing" for ensuring the rocking performance of the wall body 200, they are not limited to a specific metal fitting.

[0038] The connecting fitting 3 is preferably a metal material having a degree of elasticity that allows the unity between the panel mounting fitting 2 and the weight-receiving fitting 1 to be stably maintained by the action and effect of each of the above-mentioned locking parts until the construction of the lightweight aerated concrete panel is completed, and that elastically or plastically deforms to the extent necessary to exhibit the locking function due to the pressure applied to the connecting fitting 3 even in a situation where the locking function of the ALC panel wall should be exhibited due to vibrations such as earthquakes. Examples of preferred metal materials that can meet such requirements for the connecting fitting 3 include iron, aluminum, and stainless steel. In addition, taking into account economy and ease of processing, it is particularly preferable to use iron among the above.

[0039] [Joining through hole] As shown in Fig. 1, Fig. 2, and Fig. 3, the weight receiving horizontal plate 11 constituting the weight receiving fitting 1 and the panel mounting plate 21 constituting the panel mounting fitting 2 have a joint through hole 4 formed therethrough. The joint through hole 4 is formed at a position passing through the apex of the protrusion 22 and the contact point with the apex of the protrusion 22 on the surface facing the protrusion 22 (see Fig. 2 and Fig. 7). The position at which the joint through hole 4 is formed in the weight receiving horizontal plate 11 may be the center position in the lateral direction (direction parallel to the folded side) of the weight receiving horizontal plate 11 (see Figs. 1 and 3), and may be any position (see Fig. 2) that is the center or closer to the tip of the weight receiving horizontal plate 11 in the depth direction and allows the protrusion 22 to be stably mounted. Furthermore, the position where the joint through hole 4 is formed in the panel mounting plate 21 may be the center position in both the vertical and horizontal directions of the panel mounting plate 21 .

[0040] In the mounting hardware 10, the weight-supporting hardware 1 and the panel mounting hardware 2 are swingably connected and integrated by a connecting hardware 3 which is inserted from the top opening of the panel mounting plate 21 of the joint through hole 4 formed at the above-mentioned position to the bottom opening of the weight-supporting horizontal plate 11.

[0041] As shown in FIG. 5, the joint through hole 4 is preferably an ellipse having a minor axis r2 shorter than the width W1 of the connecting fitting 3 in its horizontal cross section. Alternatively, the joint through hole 4 may be a rectangular slit (not shown) having a gap width (short side) shorter than the width W1 of the connecting fitting 3. This can avoid the locking function from being hindered due to the connecting fitting 3 rotating unnecessarily in the joint through hole 4 as described above. In addition, in the joint through hole 4, the major axis r1 of the horizontal cross section (or the length of the slit) is set to r1>W1 with respect to the width W1 of the connecting fitting 3, and each corner of the V-shaped locking portion 32 is pressed against the inner peripheral surface of the joint through hole 4 to stably maintain the joint state.

[0042] When the joint through hole 4 is a rectangular slit as described above, it is easier to design the size and shape of the through hole to prevent the connecting fitting 3 from unnecessarily rotating in the joint through hole 4, compared to when the joint through hole is an elliptical through hole having a horizontal cross section. However, when forming a slit in a steel material having a certain thickness, due to the nature of general metal processing, it is often necessary to form a slit of a certain size or larger, and there is a concern that this will result in a decrease in the strength of the metal itself. In this regard, it is advantageous to have a through hole having an elliptical horizontal cross section.

[0043] [Locking mechanism operation] The connecting metal fitting 3 constituting the mounting hardware 10 functions as a part that joins the two metal fittings that constitute the main parts of the mounting hardware 10 and stably maintains their unity, at least until the installation of the ALC panel 20 is complete. When the locking mechanism operates in the wall 200 formed using the mounting hardware 10 or the mounting structure 100 for the lightweight aerated concrete panel, the connecting metal fitting 3 joining the panel mounting metal fitting 2 and the weight-receiving metal fitting 1 deforms appropriately, allowing the locking mechanism to operate smoothly.

[0044] <Mounting hardware assembly kit> The mounting hardware 10 of the present invention can also be used as a "mounting hardware assembly kit" in which the weight support bracket 1, panel mounting bracket 2, and connecting bracket 3 are combined into one set in a separate state before being integrated. For example, the mounting hardware 10 can be used after being delivered to the construction site of a wall 200 using ALC panels in an integrated state, but it is also possible to form the wall 200 by carrying out, for example, as shown in Fig. 3, a hardware assembly kit, which is a combination of parts before being integrated, to the construction site, and performing the steps of assembling the mounting hardware 10 by integrating this mounting hardware assembly kit and placing the ALC panel 20 on the mounting hardware 10 thus assembled, all at the installation site of the ALC panel wall.
