Description

  The present invention relates to a mounting structure for an ALC (lightweight cellular concrete) panel used as an outer wall or a partition wall in a building such as a building.

  The ALC panel is widely used as an outer wall of a building such as a building, in particular, a steel structure building. For example, as described in Patent Documents 1 and 2 below, such an ALC panel is generally used as follows. It is manufactured by such a process. That is, normally, a plurality of ALC panels are manufactured at the same time, and reinforcing bars such as a plurality of reinforcing bar mats embedded in each panel are suspended in a mold formwork (molding formwork) by support pins. In a fixed state, the ALC raw material slurry is charged into the mold to form an ALC molded body, and when the molded body is hardened to a predetermined hardness, the support pins are pulled out from the molded body and removed. The mold is removed, the molded body is cut into a panel shape with a wire such as a piano wire between adjacent reinforcing bars, and then steam-cured with an autoclave or the like to obtain an ALC panel having a predetermined size and shape. is there.

  Moreover, as a method of attaching the ALC panel as described above to a building frame such as a pillar or beam of a building, for example, as described in Patent Document 3 below, a base steel material (ruler angle) for positioning the building frame is used. Mounting, ALC panel is attached to this base steel material using panel mounting brackets such as so-called Inazuma plate and support plate. On the other hand, the panel mounting bracket is generally attached by screwing a bolt to an anchor inserted in the ALC panel, and an anchor insertion hole for inserting the anchor into the panel has been conventionally disclosed in the following patent. In general, it is perforated by a dedicated perforating apparatus or the like in the manufacturing process of the ALC panel as described in Reference 4, or by using a dedicated tool or the like at the time of panel construction as described in Patent Document 5 below.

  However, it is cumbersome and troublesome to perform the above drilling work separately from the panel manufacturing process and construction work using a dedicated drilling device or tool, whether in the process of manufacturing an ALC panel or during construction. In addition, there are problems such as a decrease in panel manufacturing efficiency and workability, and an increase in manufacturing cost and construction cost. In addition, reinforcing bars are normally embedded in the ALC panel as described above, and if there are variations or accuracy errors in the embedded position or the drilling position of the anchor insertion hole, a tool such as a drill will be used for reinforcement. There is a risk that the work efficiency and the yield may be reduced due to damage or breakage of the tool and the reinforcing steel bar due to interference with the steel bar. In particular, in the case of an ALC panel having a thickness of 75 mm or less, there is a problem that the yield is remarkably lowered because there is almost no margin between the reinforcing reinforcing bar and the anchor insertion hole.

  The present invention has been proposed in view of the above-mentioned problems. ALC panels can be manufactured easily and inexpensively and easily and reliably in a building frame without lowering the production efficiency, workability, yield, etc. of the ALC panels. An object is to provide an ALC panel mounting structure that can be mounted and supported.

  In order to achieve the above object, the ALC panel mounting structure according to the present invention has the following configuration. That is, in a state where the reinforcing reinforcing bars embedded in the ALC panel are suspended and fixed in the mold mold frame by the support pins, the raw material slurry is poured into the mold mold frame to form an ALC molded article, and the molded article When the ALC panel is fixed to a predetermined hardness, the ALC panel is manufactured by pulling out and removing the support pin, and the ALC panel is constructed using the pin hole after the support pin is pulled out and removed. An anchor is inserted therein, a panel mounting bracket is attached to the anchor, and the ALC panel is mounted on the building frame via the panel mounting bracket.

  As described above, the ALC panel is attached to the building frame by using the pin hole after the support pin with the reinforcing reinforcing bar suspended and fixed at the time of manufacturing the ALC panel as the insertion hole for inserting the anchor. Therefore, the troublesome process of drilling a dedicated anchor insertion hole during the manufacturing process of the ALC panel or the construction of the ALC panel as in the prior art is reduced, and the manufacturing efficiency and workability of the ALC panel can be improved. In addition, when drilling a dedicated anchor insertion hole as in the prior art, a tool such as a drill does not interfere with the reinforcing bar, and the tool or the reinforcing bar is not damaged or broken, so that work efficiency and yield are not reduced. There is an effect that the ALC panel 1 can be easily and inexpensively attached to the building frame easily and reliably.

  Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings. FIG. 1 is an exploded perspective view showing an embodiment of an ALC panel mounting structure according to the present invention for a building such as a building, and FIG. 2 is a partial longitudinal sectional view of the panel mounting state.

  This embodiment is applied to a building such as a building, in particular, a steel structure building. The outer wall W of the building is composed of a plurality of ALC panels 1, and each ALC panel 1 is manufactured at the time of manufacturing the panel. It is attached to the building frame F of the building using the pin hole h after the formed reinforcing pin for fixing the reinforcing steel bar is pulled out. In particular, in the case of the figure, vertically long and narrow ALC panels 1 are arranged vertically and horizontally to constitute an outer wall W, and each panel 1 is made of a beam material 2 made of H-shaped steel as a building frame F using the pin holes h. It is attached to.

  In the present embodiment, the ALC panel 1 is manufactured in the same manner as the conventional example. As shown in FIG. 3, the reinforcing bars 3 such as a plurality of reinforcing bar mats are omitted by the support pins 4. In a state of being suspended and fixed in the mold frame, the raw material slurry is put into the mold frame to form an ALC molded body, and when the molded body is hardened to a predetermined hardness, the support pins are removed from the molded body and removed. At the same time, the mold is removed, and the molded body is cut into a panel shape with a wire such as a piano wire between adjacent reinforcing bars, and then steam-cured with an autoclave or the like to produce an ALC panel of a predetermined size and shape. It is a thing.

  In the case of the figure, the reinforcing reinforcing bar 3 is a structure in which the tension-side mesh body 3a and the compression-side mesh body 3b at the time of construction are integrally connected and fixed via a spacer 30 at a predetermined interval. In the present embodiment, the spacer 30 is formed in a cross beam shape by a bar or the like, and the support pin 4 is inserted into the central opening 30 a of the cross beam spacer 30. Although not shown in the drawing, the support pin 4 is provided with a locking means such as a locking projection that comes into contact with the spacer 30 to prevent the reinforcing reinforcing bar 3 from coming off and locked. When the support pin 4 is pulled out and removed from the molded body, the above-described retaining locking state is released by retreating or revolving from the contact engagement position with the spacer 30. ing.

  In the ALC panel 1 manufactured as described above, the pin hole h after the support pin 4 is pulled out and removed as shown in FIG. 4 remains. In particular, in the present embodiment, when reinforcing reinforcing bars 3 embedded in the strip-shaped ALC panel 1 are accommodated in the mold form, the reinforcing bars 3 are horizontally long as shown in FIG. The pin holes h after the support pins 4 are pulled out and removed remain at both ends in the longitudinal direction of the ALC panel 1. . Further, in the present embodiment, each pin hole h penetrates the central opening 30a of the above-mentioned cross-shaped spacer 30 from one long side small edge surface of the ALC panel 1 (on the formwork top side at the time of manufacture). In the panel 1 reaching the opposite side of the long side edge (on the bottom of the formwork at the time of manufacture), it is formed substantially perpendicular to both the long edge and edge and substantially parallel to the short edge. .

  In the embodiment of FIGS. 1 and 2, an anchor is inserted into the panel 1 using the pin hole h of the ALC panel 1 manufactured as described above, and a panel mounting bracket is attached to the anchor. The ALC panel is mounted on the building frame F through the panel mounting bracket.

  In the case of the figure, cylindrical or rod-shaped anchors 6a and 6b are respectively inserted into both pin holes h remaining at both ends in the longitudinal direction of the ALC panel 1 (upper and lower ends in the illustrated example), and one of them (in the figure, A steel plate 9 made of an angle material integrally provided by welding or the like on the upper surface of the building frame F is attached to the anchor 6a on the upper side) with a bolt 7a. And a support plate 8b as another panel mounting bracket attached to the base steel material 9 by welding or the like and attached to the other anchor 6b (lower side in the figure) with bolts 7b.

  The bolts 7a and 7b for attaching the Inazuma plate 8a and the support plate 8b as the panel mounting brackets to the anchors 6a and 6b are inserted into the ALC panel 1 through the holes h1 formed in a direction perpendicular to the pin holes h, and anchored. What is necessary is just to screw in the internal thread hole 60 formed in the longitudinal direction center part of 6a * 6b, and the hole h1 should just be formed at the time of the manufacture process of ALC panel 1, or construction. If tapping bolts or the like are used as the bolts 7a and 7b, they can be screwed into the anchors 6a and 6b simultaneously with the drilling of the hole h1.

  Further, the support plate 8b is formed in a substantially T shape by a vertical piece 81 in a substantially vertical direction and a horizontal piece 82 provided in a direction substantially perpendicular to the vertical piece 81 and integrally by welding or the like. ALC panel 1 is placed. The support plate 8b can be attached to the base steel material 9 with bolts and nuts.

  As described above, the ALC panel mounting structure according to the present invention is for inserting the anchor holes 6a and 6b into the pin holes h after the support pins 4 with the reinforcing reinforcing bars 3 suspended and fixed at the time of panel manufacture are removed. Since the ALC panel 1 is attached to the building frame using the insertion hole, the ALC panel 1 does not have the trouble of drilling a dedicated anchor insertion hole during the manufacturing process of the ALC panel 1 or the construction of the ALC panel. 1 production efficiency and workability can be improved. In addition, when drilling a dedicated anchor insertion hole as in the prior art, a tool such as a drill does not interfere with the reinforcing bar, and the tool or the reinforcing bar is not damaged or broken, so that work efficiency and yield are not reduced. The ALC panel 1 can be easily and inexpensively attached to the building frame easily and securely.

  When the anchors 6a and 6b are inserted and fitted into the central opening 30a of the spacer 30, as shown in FIGS. 5 and 6, for example, the ALC panel 1 is firmly attached to the building frame as required. be able to. FIG. 5 shows that the both ends of the anchor 6a extend and project into the central openings 30a of the pair of spacers 30 provided in the vicinity of both ends in the width direction (left and right direction in the figure) of the strip-like vertically long ALC panel 1. FIG. 6 shows an example in which both ends of the anchor 6a are inserted and fitted into the central opening 30a of a pair of spacers 30 provided in the vicinity of the central portion in the width direction of the ALC panel 1 similar to the above. The anchor 6b can be similarly configured.

  Moreover, although the above embodiment utilized the pin hole h remaining at both longitudinal ends of the ALC panel 1 as the anchor insertion hole, not only the end but also the pin hole h remains at other positions, The pin hole can be used as an anchor insertion hole. Even when two or more pin holes h remain as in the above embodiment, at least one of them is used as an anchor insertion hole, and the other pin holes h are used as anchor insertion holes. Alternatively, a separate dedicated anchor insertion hole may be formed during the manufacturing process or construction of the ALC panel 1 as in the conventional example.

  For example, in order to provide the position of the pin hole h at a position necessary for construction, that is, a position suitable for attachment to the building frame F such as the beam member 2 as described above, the position of the spacer 30 is adjusted as appropriate. However, since the ALC panel is generally a system that simultaneously produces a plurality of panels in one mold form, the spacer 30 is necessary for construction due to restrictions such as the dimensions of the panel formed by the mold form. In order to always match the correct position, the number of panels produced by the mold form is limited, and the production efficiency may deteriorate. In such a case, only the pin hole that can be installed at a position necessary for construction is used as the anchor insertion hole, and the other dedicated anchor hole is used for the conventional dedicated hole that allows the drilling position to be freely set. Then, it can prevent that production efficiency deteriorates as mentioned above.

  Furthermore, although the said embodiment demonstrated as an example the case where the Inazuma plate 8a and the support plate 8b were used as a panel mounting bracket, it is not necessarily restricted to this. Moreover, although the said embodiment arrange | positioned ALC panel vertically long and formed the outer wall of a building, it is applicable also when arrange | positioning ALC panel horizontally, and is not restricted to the outer wall of a building, A partition wall Etc.

  As described above, according to the ALC panel mounting structure of the present invention, the pin hole after the pulling and fixing support pin for the reinforcing reinforcing bar embedded in the ALC panel is removed as an insertion hole for inserting the anchor. Since the ALC panel is attached to the building by using it, there is no trouble of drilling a dedicated anchor insertion hole during the manufacturing process of the ALC panel or during the construction of the ALC panel, and the manufacturing efficiency and workability of the ALC panel are improved. In addition, when drilling a dedicated anchor insertion hole as in the prior art, a tool such as a drill interferes with the reinforcing bar and the tool or reinforcing bar is damaged, or the yield of the ALC panel is reduced. This type of panel mounting structure is extremely effective industrially.
