TECHNICAL FIELD The present invention relates to an exterior wall height adjustment fitting for adjusting the installation height of an exterior wall panel.

In general, the installation height of exterior wall panels is determined based on the beam material, but it is finely adjusted in units of several millimeters at the construction site, taking into consideration the balance between the patterns and joint widths of adjacent exterior wall panels. When finely adjusting the installation height of the exterior wall panel at the construction site in this way, it is often the case that the exterior wall panel is lifted by inserting a bar into the lower portion of the exterior wall panel from the outside. However, this method has a problem that the surface of the outer wall panel is damaged by the crowbar. Therefore, inventions have been proposed in which the installation height of the exterior wall panel can be adjusted from the indoor side (for example, Patent Literature 1 and Patent Literature 2).

The invention described in Patent Literature 1 describes an adjusting metal fitting fixed to the lower end portion of the outer wall panel. The adjustment metal fitting is inserted through an L-shaped fixed plate portion that is fixed to the indoor side surface of the exterior wall panel and has a horizontal plate portion that protrudes toward the indoor side, and a female screw hole formed in the horizontal plate portion. The installation height of the exterior wall panel can be easily adjusted without damaging the surface of the exterior wall panel by rotating the bolt screwed into the female threaded hole from the indoor side.

In addition, the invention described in Patent Document 2 describes a receiving metal fitting that is locked to the lower end of the outer wall panel. Similar to the adjustment metal fitting of Patent Document 1, a bolt is attached to the L-shaped metal fitting that protrudes indoors. It is disclosed that the installation height of the exterior wall panel is adjusted by screwing it in and rotating the bolt from the indoor side.

Further, as shown in the figure, the inclined plate portion 23c is formed with a female screw hole 23d through which the bolt 4 can be inserted, so that the shaft portion 41 of the bolt 4 can be screwed into the female screw of the inner peripheral surface.

The second metal plate 3 shown in FIGS. 1 and 3 is a member installed between the blades 24 of the first metal plate 2 , and one plate surface 31 a is a plate on the extension plate portion 23 side of the vertical plate portion 21 . a fixing plate portion 31 that abuts on the first plate surface 21e that is a surface; A bent plate portion 33 is formed by bending an upper end portion 31c of the plate portion 31 in the direction opposite to the vertical plate portion 21, and a tip portion 33a of the bent plate portion 33 is bent in the direction of the vertical plate portion 21. and a bent plate portion 34 with a tip 34a abutting on the first plate surface 21e of the vertical plate portion 21 . The fixed plate portion 31 is a portion for fixing the first metal plate 2 so as to be movable in the vertical direction, and as shown in the figure, a long hole 31d extending in the vertical direction is formed substantially in the center in the horizontal direction. The elongated hole 31d is formed at a position aligned with the through hole 21d when the fixing plate portion 31 is superimposed on the vertical plate portion 21, and the low head bolt 5 can be inserted therethrough. The long hole 31d is formed by adjusting the length and position so that the low head bolt 5 can move vertically by about 10 mm to 20 mm.

The bent plate portion 33 is preferably formed by bending the upper end portion 31c of the fixed plate portion 31 at an obtuse angle. Further, the angle θ2 between the fixed plate portion 31 and the bent plate portion 33 is preferably about 130 degrees to 140 degrees, and in this embodiment it is 135 degrees. It is the same as the tilt angle. On the other hand, the bent plate portion 34 is a portion against which the tip 41a of the bolt 4 inserted through the female screw hole 23d is pressed. parallel. The bending plate portion 34 is preferably formed by bending the tip portion 33a of the bending plate portion 33 at a right angle as shown in the drawing. Since the bent plate portion 33 reinforces the bent plate portion 34 when pressed against the portion 34, deformation of the bent plate portion 34 can be effectively suppressed.

As shown in FIG. 1, the first metal plate 2 and the second metal plate 3 are formed by overlapping the fixed plate portion 31 and the vertical plate portion 21 and connecting the through holes 21d and the elongated holes 31d with the low head bolts 5 to form low head bolts. By tightening the nut 6, they are connected and fixed to each other. On the other hand, the bolt 4 is inserted into the female screw hole 23 d from above, and the tip 41 a of the shaft portion 41 is in contact with the upper end surface 34 b of the bending plate portion 34 . Although each dimension of the outer wall height adjustment fitting 1 is not particularly limited, the overall height H1 when the locking plate portion 22 is brought into contact with the mounting plate portion 32 is about 130 mm to 140 mm, and the mounting plate portion 32 The distance L1 from the tip 32a to the tip 23f of the extension plate portion 23 is about 60 mm to 70 mm, and the width W1 of the vertical plate portion 21 shown in FIG. 2 and the width W2 of the fixed plate portion 31 shown in FIG.

Even when the height adjusting metal fitting 1 is installed in an unstable place such as a rising part of a balcony, it can be installed in a stable state without taking up space.

When the outer wall height adjusting fitting 1 formed in this manner is installed on a horizontal surface and the bolt 4 is rotated, the inclined plate portion 23c moves obliquely along the axial direction of the bolt 4. As shown in FIG. For example, when the bolt 4 is rotated clockwise as viewed from the head 42 side, the inclined plate portion 23c moves toward the head 42 side. At this time, the vertical plate portion 21 is restrained by the low-head bolt 5 and the low-head nut 6, and the tip 34a of the bending plate portion 34 abutting on the first plate surface 21e. It moves only upward along the slot 31d. Conversely, when the bolt 4 is rotated counterclockwise when viewed from the head portion 42 side, the inclined plate portion 23c moves toward the tip 41a of the shaft portion 41 . Also in this case, since the vertical plate portion 21 is connected and fixed to the fixed plate portion 31, horizontal movement thereof is suppressed, and the vertical plate portion 21 moves only downward along the long hole 31d. As shown in the figure, the tip 41a of the bolt 4 is located closer to the vertical plate portion 21 than the head portion 42 according to the inclination of the inclined plate portion 23c. A rotation operation is added to 42 .

Next, the outer wall panel P whose height is adjusted by the outer wall height adjusting bracket 1 will be described. The outer wall panel P shown in FIGS. 4 and 5 is a member constituting the outer wall of the building, and is installed facing the balcony B in this embodiment. The outer wall panel P has a plate-shaped outer wall finishing material P1 and a pair of vertical rails P2 fixed to both ends of the outer wall finishing material P1 in the width direction on the back surface P1a side of the outer wall finishing material P1. is doing. The exterior wall finishing material P1 is a plate material having a width of about 1000 mm to 1020 mm, which is formed by molding precast concrete to a uniform thickness, and the surface P1b is decorated. Further, the vertical rail material P2 is embedded in the exterior wall finishing material P1 in a state of opening to the indoor side.

As shown in FIG. 4, the outer wall panel P formed in this way is installed above the rising plywood Y erected on the steel frame beam X, and further to the indoor side than the rising plywood Y. It is supported and fixed to the frame member Z to be installed. The plywood board Y consists of a first plywood board Y1 that serves as a base and a second plywood board Y2 that is installed outside the first plywood board Y1. Receiving metal fittings Y3, which are higher than the plywood board Y1 and receive both ends of the outer wall panel P in the width direction, are installed on the upper end surface Y2a. In addition, the frame member Z has a plurality of frame column members Z1 erected on the steel frame beam members X, and a frame frame horizontal member Z2 placed on the upper end surface of the steel frame beam members X, The framing pillars Z1 are arranged at the portions where both ends in the width direction of the exterior wall finishing material P1 are located.

As shown in FIG. 5, the outer wall panel P is bolted to the framing column member Z1 with a dedicated metal fitting (not shown) with the lower end surface Pa separated from the upper end surface Y2a of the second plywood Y2 by about ten and several millimeters. be. The second plywood Y2 positioned at the bottom of the outer wall panel P is a plate material with a thickness of about 18 mm to 20 mm, and has a very large depth width compared to the horizontal frame member Z2 positioned at the bottom of the outer wall panel P. narrow. Therefore, the installation height of the outer wall panel P cannot be adjusted with the conventional adjusting metal fittings, which are supposed to be placed on the horizontal frame member Z2.

Next, a method for adjusting the height of the outer wall panel P using the outer wall height adjusting fitting 1 will be described. First, the bolts that fix the outer wall panel P to the framework pillar Z1 are loosened in advance, and the outer wall panel P is temporarily fixed in a state in which it can be slightly moved in the vertical direction. Then, as shown in FIG. 5, the locking plate portion 22 of the outer wall height adjusting fitting 1 is inserted from the indoor side between the outer wall panel P and the second plywood board Y2, and the placing plate portion 32 is raised to the second rising position. It is placed on the upper end surface Y2a of the plywood Y2. At this time, since the mounting plate portion 32 protrudes to the outdoor side, it can be mounted on the second plywood board Y2 having a narrow depth width without any problem.

Next, as shown in FIG. 6, the bolt 4 is rotated by a dedicated tool to bring the locking plate portion 22 into contact with the lower end surface Pa of the outer wall panel P, and the bolt 4 is further rotated to apply the first metal plate. 2 is moved upward to finely adjust the installation height of the outer wall panel P. At this time, the inclined plate portion 23c of the first metal plate 2 is inclined with respect to the horizontal plate portion 23a. The moving speed of the plate 2 in the vertical direction becomes 1/√2 times. Therefore, it is possible to more finely adjust the installation height of the exterior wall panel P while considering the balance between the patterns and joint widths of the adjacent exterior wall panels P, and improve the construction accuracy. Further, since the head 42 of the bolt 4 is directed toward the indoor side, the worker can easily rotate the bolt 4 .

After adjusting the outer wall panel P to the desired height, the bolts that fix the outer wall panel P to the framework pillars Z1 are finally tightened to complete the installation of the outer wall panel P. In this manner, the outer wall height adjusting metal fitting 1 of the present application presses the tip 41a of the bolt 4 against the upper end surface 34b of the bending plate portion 34, so that the tip of the bolt can be pushed to the outer wall panel P like the conventional outer wall height adjusting metal fitting. There is no need to press against structures such as building foundations and crossbeams located below. Therefore, even when a structure with insufficient depth width is installed under the outer wall panel P, the installation height of the outer wall panel P can be adjusted by rotating the bolt 4 in a stable state.

In this embodiment, the case where the axial direction of the bolt 4 is inclined has been described, but as shown in FIG. Extending, the axial direction of the bolt 4 may be oriented in the vertical direction. In that case, the entire extended plate portion 23 of the first metal plate 2 is extended in the horizontal direction, and the bent plate portion 33 is extended in the horizontal direction without forming the bent plate portion 34 on the second metal plate 3. good. By pressing the tip 41a of the bolt 4 against the bent plate portion 33 and rotating the bolt 4, the installation height of the outer wall panel P can be adjusted.

The embodiments of the present invention are not limited to those described above, and can be modified as appropriate without departing from the spirit of the present invention.

The exterior wall height adjustment fitting according to the present invention can be suitably used when the exterior wall panel is positioned above a shed or above a balcony.
