Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outer wall panel mounting structure and mounting bracket, and more particularly to an outer wall panel mounting structure and mounting bracket when a panel such as lightweight cellular concrete is mounted on a steel frame of a building to form an outer wall.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, various construction methods have been implemented when a lightweight cellular concrete panel is attached to a steel frame of a building to configure an outer wall.
[0003]
In Japanese Utility Model Publication No. 5-28243, a clip attached to the back surface of the upper part of the panel and formed of an elastic member having a substantially U-shaped side surface, one end portion is inserted into the curved portion, and the other end portion is fixed to the structural housing. A structure is shown in which the fixing bracket is clamped by tightening the clip with a bolt.
[0004]
However, when the panel swings due to an earthquake or the like, there is a problem that the panel is damaged due to friction between the metal fittings even if the fixed metal fitting can move relative to the clip. In addition, the clip has a complicated shape and is expensive to process.
[0005]
Japanese Patent Publication No. 5-54546 discloses a support metal fitting that is attached to the back surface of the upper part of the panel, has a substantially U-shaped side surface, and has a notch. A structure consisting of a fixing bracket to be fixed is shown. In particular, a protrusion is provided in the notch so that the support fitting is in sliding contact with little friction in the notch.
[0006]
However, since the receiving member is fastened with bolts and fixed to the building frame, there is a problem that the panel cannot be damaged due to an earthquake or the like.
[0007]
Alternatively, for example, there is a dry construction method in which a partially broken perspective view is shown in FIG. 11 and a longitudinal sectional view is shown in FIG.
[0008]
In this construction method, the hole 1b is perforated from the vicinity of the upper end of the long side edge of the lightweight cellular concrete panel 1 having a width of 600 mm, a length of 2400 to 3000 mm, and a thickness of about 100 mm, or not shown, A hole is perforated from the upper and lower short side facets, and an anchor 7 having a pipe shape of about 150 mm in length and provided with a screw hole in a perpendicular direction at the center is embedded.
[0009]
Further, a hole 1 a communicating with the screw hole of the anchor 7 is drilled from the back surface of the lightweight cellular concrete panel 1. At the upper end portion of the lightweight cellular concrete panel 1, a self-weight receiving metal fitting 4 having a T-shaped cross section is provided at a screw hole of the anchor 7 with a long hole below the vertical surface 4c and a bolt 6 penetrating the hole 1a. Fasten. Further, a step-shaped Inazuma type metal fitting 5 is fastened to the lower end portion of the lightweight cellular concrete panel 1 in a screw hole of the anchor 7 with a long hole on one surface and a bolt 6 inserted into the hole 1a. To do. These bolts 6 have slightly thin tips, and a washer 6a is set under the head.
[0010]
On the other hand, a horizontal plane 3b of a ruler angle 3 is fixed to a desired position on the upper and lower horizontal beams 2 of the frame.
[0011]
And the other side of the Inazuma type metal fitting 5 in the state where the lightweight cellular concrete panel 1 is suspended and the lower end of the lightweight cellular concrete panel 1 is supported on the horizontal portion 4a of the weight receiving metal fitting 4 attached to the lower lightweight cellular concrete panel 1. However, it positions so that the vertical surface 3a of the lower ruler angle 3 may be pinched. Further, the vertical surface of the weight holder 4 fastened to the upper end of the lower lightweight cellular concrete panel 1 is brought into contact with the vertical surface 3 a of the upper ruler angle 3. Then, the lightweight cellular concrete panel 1 and the adjacent lightweight cellular concrete panel 1 are positioned so as to form a vertical wall surface by fitting the actual part 1c of each long side small edge surface, and the Inazuma type The vertical part 5 b at the lower end of the metal fitting 5, the upper part of the vertical surface 4 c of the weight receiving metal fitting 4, and the corners between the vertical surface 4 c and the horizontal surface 4 a are welded to the ruler angle 3.
[0012]
Therefore, when the frame is swung in the horizontal direction due to an earthquake or the like, the lightweight cellular concrete panel 1 is locked with the bolts 6 with the upper and lower end metal fittings fastened, so that the lightweight cellular concrete panel 1 is damaged. Can be prevented.
[0013]
Thereafter, the lightweight cellular concrete panel 1 of the same level is sequentially attached adjacent to the lightweight cellular concrete panel 1, and then the lightweight cellular concrete panel 1 of the upper level is similarly installed. The joints at the upper and lower ends of the lightweight cellular concrete panel 1 are sandwiched with a fireproof joint material 11 such as rock wool when the upper lightweight cellular concrete panel 1 is attached, and then, as shown in FIG. A backup material 9 such as foamed styrene is fitted from the outside, and a sealing material 22 is filled on the outside.
[0014]
After that, by painting the entire outer wall or pasting tiles on the entire outer wall, it is possible to form an outer wall surface excellent in appearance and earthquake resistance.
[0015]
However, in this mounting structure, when a tile (not shown) is pasted, if the lightweight cellular concrete panel 1 is largely locked, the tiles at the four corners of the adjacent lightweight cellular concrete panel 1 are subjected to stress acting in the horizontal direction. There is a problem that the surface of the lightweight cellular concrete panel 1 is easily damaged.
[0016]
In order to prevent this problem, there is a method of using a special joint material of an elastic body, but there is a problem that it is expensive and troublesome.
[0017]
Alternatively, a fixing bracket having a long hole and a mounting bracket made of a support bracket having a U-shaped cross-section provided with a hole that can be inserted in the transverse direction with respect to the long hole and can be aligned with the long hole. It has been devised. However, the thickness of the fixing bracket is required to be about 6 mm, and the thickness of the supporting bracket is about 6 mm. Since the fixing bracket has a thickness on both sides of the supporting bracket, the total thickness including the thickness of the washer is about 40 mm was also required. In order to obtain good workability between the beam and the lightweight cellular concrete panel, it is preferably about 30 mm, and the mounting bracket has a problem that it is slightly too thick.
[0018]
In addition, if the space between the beam and the lightweight cellular concrete panel is large, a large L-shaped angle must be used, which increases the cost.
[0019]

[0025]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to the drawings.
[0026]
FIG. 1 is a partially broken perspective view showing a mounting structure of an outer wall panel according to the present invention. Since some metal fittings are attached to the back surface of the lightweight cellular concrete panel, the upper lightweight cellular concrete panel is not shown, and a part of the lower lightweight cellular concrete 1 is broken and illustrated. 2 is a longitudinal sectional view of FIG. 1, and FIGS. 3 to 5 are perspective views of metal fittings used in the mounting structure of the present invention.
[0027]
The mounting structure of the present invention relates to the upper end portion of the outer wall panel, but the entire outer wall panel is mounted as follows. That is, as shown in FIGS. 1 and 2, at the lower end portion of the outer wall panel 1, each of both ends of the lower end edge surface of the adjacent outer wall panel 1 is supported by the self-weight bracket 12 welded and fixed to the ruler angle 3. The Inazuma type metal fitting 5 fixed to the ruler angle 3 is fixed to the anchor 7 embedded in the center of the lower end of the outer wall panel 1 with a bolt 6. At the upper end of the outer wall panel 1, the protruding portion of the support fitting 14 is passed through the long hole 13 a of the fixing fitting 13 welded and fixed to the ruler angle 3, and the bolt 6 is inserted into the through hole 14 a of the support fitting 14 via the washers 6 a and 6 b. And the tip of the bolt 6 is fixed to the anchor 7 embedded in the upper end of the outer wall panel 1. The ruler angle 3 is fixed to the building housing 2 such as a beam with a desired width.
[0028]
As shown in FIG. 3, the self-weight bracket 12 includes two horizontal flat surfaces 12 a and a vertical flat portion 12 b for welding.
[0029]
As shown in FIG. 4, the fixing metal 13 has a sectional cross-sectional shape and has a long hole 13 a formed on one flat surface.
[0030]
As shown in FIG. 5, the support metal fitting 14 is obtained by welding a protruding portion 14b to a flat plate portion 14c, and has a through hole 14a penetrating therethrough. The through hole 14a extends in the thickness direction of the fixing bracket 13 to form a protruding portion 14b. In the illustrated example, the height of the protruding portion 14b is set higher than the thickness of the fixing metal 13 by the amount of the washers 6a and 6b. Since the bolt 6 passes through the through hole 14 a of the support metal 14 and is fixed to the anchor 7 embedded in the upper end portion of the outer wall panel by the bolt member 6, the protruding portion 14 b is the width of the long hole 13 a of the fixing metal 13. A cylindrical shape with the same or slightly smaller diameter. Therefore, the support fitting 14 can rotate around the axis of the through hole 14a. The through hole 14a may be a bolt hole having a screw thread to which the bolt 6 can be fastened.
[0031]
FIG. 6 shows a support metal 24 that is different from the support metal 14. The support bracket 24 is formed by bending a pair of parallel projecting portions 24b on a deformed flat plate portion 24c. The pair of projecting portions 24 b are dimensioned so as to fit into the long holes 13 a of the fixing bracket 13. In this case, the support metal 24 does not rotate when the bolt 6 passes through the through hole 24a of the support metal 24 and is fastened to the anchor embedded in the upper end portion of the outer wall panel. Therefore, the protruding portion 24 b of the support metal 24 is in contact with the bolt 6 and has a shape that can easily slide in the horizontal direction within the long hole 13 a of the fixing metal 13. In addition, when using the support metal fitting of FIG. 6, the opening of washer 6a, 6b is made into a rectangle together with the parallel protrusion part 24b.
[0032]
The support fitting 34 in FIG. 7 is formed by welding a pair of parallel protrusions 34b to a rectangular plate 34c. A through hole 34a is provided in the center.
[0033]
FIG. 8 shows a support bracket 44 in which a flat portion 44c and a bowl-shaped protrusion 44b are formed by cutting a plate material. A through hole 44a is provided in the center. Since the support metal fitting 44 has a bowl shape, the contact area with the inner surface of the long hole 13a of the fixing metal fitting 13 is reduced.
[0034]
The shape of the protrusion, the long hole, and the dimensions of the bolt member are related so that the relative movement of the support metal fitting and the fixing metal fitting can be performed smoothly.
[0035]
In the lightweight cellular concrete panel mounting structure according to the present invention, the lower end portion of the lightweight cellular concrete panel 1 is supported on its own weight receiving metal 12 fixed to the building housing 2 at both ends of the small edge surface, and the center portion is inazuma type. Since it is fixed by the metal fitting 5, it does not lock. Since the upper end portion of the lightweight cellular concrete panel 1 is relatively slidable between the support metal fixture 14 fixed to the lightweight cellular concrete panel 1 and the fixture metal fixture 13 having a long long hole 13a in the horizontal direction. There is a certain degree of freedom with respect to the building frame 2. Accordingly, each adjacent lightweight cellular concrete panel 1 exhibits a synchronized movement with respect to the swinging of the building housing 2, and therefore, the tiles 20 at the four corners attached to each lightweight cellular concrete panel 1 have a horizontal direction. This prevents the tile 20 from peeling off and the lightweight cellular concrete panel 1 from being damaged.
[0036]
Further, the support metal fitting 14, the fixing metal fitting 13 and the self-weight receiving metal fitting 12 have a simple structure and can be installed by a dry method, so that the mounting work is also easy. In addition, although the protrusion part 14b of the support metal fitting 14 can move in the long hole 13a long in the horizontal direction of the fixed metal fitting 13, since movement is restricted at the both ends of the long hole 13a, a building frame such as a beam. Even if the swing of 2 is large, the support fitting 14 is not detached from the fixing fitting 13.
[0037]
FIG. 9 shows an example in which the fixing metal 53 is disposed between the support metal 14 and the outer wall panel 1. In this example, the fixing metal 53 is flat as shown in FIG. 10, and the height of the protruding portion 14 b of the support metal 14 is lower than the thickness of the fixing metal 53. With this structure, it is possible to minimize the overall thickness. In this case as well, a fixing bracket having the shape shown in FIGS.
[0038]
(Example)
Hereinafter, the method of attaching a lightweight cellular concrete panel is demonstrated based on FIGS.
[0039]
First, in the vicinity of the upper and lower ends of the lightweight cellular concrete panel 1, the hole 1 b is drilled from the short side facet, and the anchor 7 is embedded. Further, a hole 1a reaching the hole 1b from the back surface of the panel is opened.
[0040]
Next, at the upper end portion of the panel, a 12 mm diameter bolt 6 penetrating through the washer 6a, 6b is inserted into the anchor 8 from the rear surface of the panel to the through hole 14a of the support fitting 14 penetrating the long hole 13a of the fixing fitting 13. Fasten.
[0041]
The support fitting 14 includes a columnar protrusion 14b having a size of 40 × 40 mm, a height of 10 mm, and an outer diameter of 14 mmφ. A through hole 14a through which a 12 mm diameter bolt can penetrate is formed in the protruding portion 14b.
[0042]
The fixture 13 has a sectional cross-sectional shape, has a width of 120 mm, a height of 113 mm, a thickness of 6 mm, and opens a 15 × 80 mm long hole 13a. Cutouts of 30 × 40 mm were made in the corners at both ends of the upper end.
[0043]
Accordingly, when the protruding portion 14b of the support metal fitting 14 is inserted into the long hole 13a, the thickness of the fixing metal fitting 13 is 6 mm with respect to 8 mm between the washer 6b and the flat surface of the support metal fitting 14. Since there is a gap of 2 mm in the thickness direction of the metal fitting, and the outer diameter of the projection 14b is 14 mmφ with respect to the height of 15 mm of the long hole 13a, a gap of 1 mm is formed in the vertical direction and 66 mm in the horizontal direction. The gap is made. Therefore, the protrusion 14b can freely move in the long hole 13a.
[0044]
In addition, at the lower end of the panel, a bolt 6 is passed through a through hole on one surface of the Inazuma-type metal fitting 5 and temporarily fixed to the anchor 8.
[0045]
On the other hand, the self weight holder 12 is welded to the ruler angle 3 fixed to the beam 2 at the position of the ruler angle 3 corresponding to the back of the joint of the lightweight cellular concrete panel 1 at the same interval as the width of the lightweight cellular concrete panel 1. .
[0046]
The self-weight receiving metal fitting 12 has a self-weight receiving portion 12a having a width of 130 mm, a height of 75 mm, a thickness of 6 mm, a width of 50 mm, and a protruding width of 70 mm at both ends. The self-weight receiving portion 12a carries the lower end portion of the adjacent lightweight cellular concrete.
[0047]
The lightweight cellular concrete panel 1 is suspended from the outside of the housing, and the fixing bracket 13 is welded to the ruler angle 3 in a state where the lower end small edge surface end portion is supported on one of the own weight receiving portions 12a of the own weight receiving bracket 12.
[0048]
Here, the ruler angle 3 is sandwiched between the Inazuma metal fitting 5 and the lightweight cellular concrete panel 1 that are temporarily fixed to the lower end of the lightweight cellular concrete panel 1. After this positioning, the Inazuma type metal fitting 5 is welded to the ruler angle 3.
[0049]
After repeating the same work and attaching the lightweight cellular concrete panels 1 in sequence, the vertical and horizontal joints are filled with the refractory joint material 11, the backup material 9, the sealing material 22 and the caulking material 10 in the same manner as in the past. Wall surfaces are constructed. In this state, both ends of the lower end facet of each lightweight cellular concrete panel 1 are carried by the self-weight receiving bracket 12, and the lower-end back surface central portion is fastened to the Inazuma type bracket 5 fixed to the lower floor beam 2.
[0050]
The support metal fitting 14 fastened to the upper end portion of each lightweight cellular concrete panel 1 is not fixed to the fixing metal fitting 13 fixed to the upper floor beam 2, and the protruding portion 14b only penetrates the elongated hole 13a. is there. Therefore, when the building housing 2 swings in the horizontal direction due to an earthquake or the like, the projecting portion 14b slides in the long hole 13a of the fixing bracket 13, so that the lightweight cellular concrete panel 1 is in contact with the fixing bracket 13. Although it is movable in the horizontal direction, it does not lock, so it can prevent damage to the panel due to shaking.
[0051]
When the tile 20 is pasted, after applying a sealer to the wall surface, an adhesive is applied, and then the joint material 21 is filled in the tile joint. The ground is filled with a sealing material 22 having elasticity at all joints.
[0052]
If a wall surface is comprised as mentioned above, the outer wall excellent in the external appearance and earthquake resistance can be constructed comparatively easily.
[0053]
Further, the outer wall panel mounting structure of the present invention can be applied to an extrusion mold panel, a PC panel, and the like in addition to the lightweight cellular concrete panel shown in the embodiment.
[0054]
【The invention's effect】
As described above in detail, in the outer wall panel mounting structure of the present invention, each adjacent outer wall panel does not lock independently, and its upper end portion is synchronized and slides in the same direction. No horizontal stress acts on the tiles in the part, and the tiles are not peeled off or the outer wall panels are not damaged. In addition, the metal fittings can be manufactured at a low cost with a simple structure, and can be easily mounted.
