[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall panel mounting structure that forms a gap having a predetermined dimension between the wall panel and a base steel material when the wall panel is mounted to a housing, and a joint receiving bracket used in the mounting structure It is.
[0002]
[Prior art]
When attaching a wall panel to a steel frame, a base steel material made of an angle material is fixed to a steel beam, and a weight receiving hardware that supports the weight of the wall panel and a member called a liner or a spacer are attached to the base steel material, In general, the lower end of the wall panel is placed on the weight receiving hardware to support the weight, and the indoor side surface is attached to a liner or a spacer to be attached. The liner or spacer is disposed on both ends of the wall panel in the width direction, and has a function of maintaining a gap formed between the wall panel and the base steel material at a preset value. Some are formed (liner) and others are press-molded in a substantially U-shaped cross section (spacer).
[0003]
For example, FIG. 7 is a view for explaining a mounting structure for attaching the wall panel 53 to the base steel material 52 using the plate-shaped liner 51. In the figure, the base steel material 52 is provided on the upper flange 54a of the beam 54, and the overhang length from the flange 54a (the outdoor side of the vertical piece 52a of the base steel material 52 from the outdoor end of the upper flange 54a) The distance to the surface is maintained at a preset value and is welded. The weight piece 55 is attached to the vertical piece 52a of the base steel material 52 at a position corresponding to the approximate center of the wall panel 53, and the base steel material 52 and the wall set in advance at positions corresponding to both ends in the width direction of the wall panel 53 are attached. A liner 51 having a thickness corresponding to the size of the gap to be formed between the panels 53 is fixed by welding or bonding. In this mounting structure, the lower end of the wall panel 53 is placed on the weight receiver 55 and the surface on the indoor side is brought into contact with the liner 51, so that the gap between the wall panel 53 and the base steel material 52 is set to the thickness of the liner 51. It can be set to a corresponding value.
[0004]
FIG. 8 is a view for explaining a mounting structure using a spacer 56 (see FIG. 9) formed in a U-shape, and the configuration other than using the spacer 56 in place of the liner 51 is the same as the mounting structure described above. It is. The spacer 56 is formed by press-molding a relatively thin plate, the locking pieces 56a are formed on both sides in the left-right direction, and the contact surface 56b that contacts the wall panel 53 and the protrusion 56c are formed between the locking pieces 56a. ing. The locking piece 56a is locked to the vertical piece 52a of the base steel material 52, and is separated from the contact surface 56b by a distance corresponding to a preset gap dimension between the wall panel 53 and the base steel material 52. A notch 56d for fitting the vertical piece 52a is formed. In this mounting structure, the lower end of the wall panel 53 is placed on the self-weight receiver 55 and the interior surface is brought into contact with the contact surface 56b of the spacer 56, so that the gap between the wall panel 53 and the base steel material 52 is applied. A value corresponding to the distance between the contact surface 56b and the notch 56d can be set.
[0005]
[Problems to be solved by the invention]
In the mounting structure using the liner 51, it is essential that the liner 51 has a thickness equal to the gap dimension set between the base steel material 52 and the wall panel 53, which increases the material cost, When 51 is fixed to the vertical piece 52a of the base steel material 52, welding or bonding is indispensable, and there is a problem that work costs increase.
[0006]
Further, in the mounting structure using the spacer 56, it is essential that the locking piece 56a straddles the vertical piece 52a of the base steel material, and if this hooking cost is L, the material cost of L × 2 will increase. Further, in order to perform the operation of locking the spacer 56 to the vertical piece 52a of the base steel material, it is necessary to provide a gap larger than L on the indoor side of the piece 52a, and a column is provided at a position where the spacer 56 is to be attached. In some cases, attachment may be difficult.
[0007]
An object of the present invention is to improve workability by attaching a wall panel to a base steel material using a joint fitting that can be easily attached to the steel material even when there is no large gap on the indoor side of the base steel material. An object of the present invention is to provide a wall panel mounting structure that can be improved and a joint receiving bracket that can reduce material costs more than the liner or spacer.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the wall panel mounting structure according to the present invention uses a joint receiving bracket so as to form a predetermined gap between the wall panel and the base steel material when the wall panel is mounted to the housing. The wall panel mounting structure is configured to bend both ends in the width direction of the panel receiving surface in accordance with the gap size, and form a bent piece whose tip abuts on the base steel material and a panel receiving surface in contact with the wall panel. And a joint receiving bracket formed with at least one locking piece to be locked to the base steel material by cutting out a part of the panel receiving surface and at least one abutting piece whose tip abuts the base steel material, The receiving metal fittings are arranged on both sides in the width direction of the wall panel and are locked to the base steel material via the locking pieces, and the wall panel is attached in contact with the panel receiving surface of the joint receiving metal fitting.
[0009]
In the above mounting structure, the joint receiving bracket is attached to the base steel material by locking at least one locking piece formed by cutting out a part of the panel receiving surface of the joint receiving bracket to the vertical piece of the base steel material. I can do it. The joint receiving bracket attached to the base steel material is such that the tip of the bent piece formed on both sides in the left-right direction and the tip of at least one abutting piece formed on the panel receiving surface abut the base steel material. The distance between the base steel material and the base steel material is kept equal to a preset gap. For this reason, by attaching the wall panel in contact with the panel receiving surface, the gap between the panel and the base steel material can be maintained at a preset value.
[0010]
Further, since the joint receiving bracket is attached to the base steel material through the locking piece formed on the panel receiving surface of the metal bracket, it is not necessary to form a large gap on the indoor side of the vertical piece of the base steel material, and the column is attached to the beam. Can be easily attached without applying special processing to the base steel material.
[0011]
Further, the joint receiving bracket according to the present invention is a joint receiving bracket which is disposed between the wall panel and the base steel material and forms a gap having a preset dimension therebetween, and has a predetermined dimension. The left and right sides of the sheet are bent to correspond to the gap size to be formed between the wall panel and the base steel material, and a bent piece whose tip abuts on the base steel material and a panel receiving surface in contact with the wall panel are formed, At least one part of the panel receiving surface is cut out, and the cut piece is bent in the same direction as the bent piece, and further bent downward at a portion exceeding the length of the bent piece and the thickness of the base steel material and locked to the base steel material. And at least one portion of the panel receiving surface is cut out, and the cut piece is bent in the same direction as the bent piece to form a contact piece whose tip abuts against the base steel material. Is what .
[0012]
In the joint receiving bracket, at least one part of the panel receiving surface is cut out and the cut piece is bent in the same direction as the bent pieces formed on both sides in the left and right direction, and the length of the bent piece and the thickness of the base steel material Since the locking piece is formed by bending downward at a portion exceeding the vertical length, when the locking piece is engaged with the vertical piece of the base steel material, the vertical piece can be sandwiched between the locking piece and the bent piece. Thus, the joint receiving bracket can be attached to the base steel material. Since the bent piece has the same dimension as the gap between the preset wall panel and the base steel, the gap between the panel receiving surface and the base steel is equal to the preset gap between the wall panel and the base steel. By mounting the wall panel in contact with the panel receiving surface, the gap between the panel and the base steel material can be maintained.
[0013]

Hereinafter, an embodiment of a preferred wall panel mounting structure will be described with reference to the drawings, and an embodiment of a joint receiving bracket will be described. 1 is a perspective view of a wall panel mounting structure as viewed from the indoor side, FIG. 2 is a diagram for explaining the configuration of a joint receiving bracket, FIG. 3 is a perspective view of the joint receiving bracket viewed from the front, and FIG. 4 is a joint receiving bracket. FIG. 5 is a diagram illustrating a configuration example of a joint receiving bracket, and FIG. 6 is a diagram illustrating a configuration example of a locking piece formed on the joint receiving bracket.
[0014]
As shown in FIG. 1, the base steel material 2 which consists of an angle material is arrange | positioned at the upper flange 1a of the beam 1 which comprises the housing of a building, and the overhang | projection length from the outdoor edge part of the upper flange 1a of the vertical piece 2a is made. After adjusting to a preset value, the horizontal piece 2b is fixed by welding to the upper flange 1a.
[0015]
A plurality of wall panels 3 are continuously provided on the outdoor side of the base steel material 2, and each wall panel 3 is supported by being placed on a weight receiving hardware (not shown) and jointed between the base steel materials 2. By interposing the receiving metal fitting 4, the gap between the wall panel 3 and the base steel material 2 is maintained at a preset dimension (set dimension t), and in this state, the Inazuma type attached to the bolt provided on the wall panel 3 is used. It is attached to the vertical piece 2a of the base steel material 2 through a plate.
[0016]
The joint receiving metal fittings 4 are arranged on both sides in the width direction of the wall panel 3 so as to be opposed to the adjacent wall panels 3, and are engaged with the vertical pieces 2 a of the base steel material 2, so that the pieces 2 a and the wall panels 3 are engaged. The gap is maintained.
[0017]
The joint receiving metal fitting 4 is formed by press-molding a relatively thin plate. As shown in FIGS. 2 and 3, the bent piece 4a is bent with a dimension equal to the set dimension t on both sides in the left-right direction. The panel receiving surface 4b is formed between the bent pieces 4a. At least one locking piece 4c and at least one contact piece 4d are formed on the panel receiving surface 4b. In the joint receiving metal fitting 4 in this example, one locking piece 4c is formed at the approximate center in the left-right direction of the panel receiving surface 4b, and two contact pieces 4d are formed on both sides of the locking piece 4c. .
[0018]
The bent piece 4a has a function of maintaining the distance between the piece 2a and the panel receiving surface 4b at the set dimension t by contacting the vertical piece 2a of the base steel material 2 at the tip. Further, the panel receiving surface 4b has a function of contacting the surface 3a on the indoor side of the wall panel 3 to restrain the position of the surface 3a.
[0019]
The locking piece 4c has a function of engaging with the vertical piece 2a of the base steel material 2 to lock the joint receiving bracket 4, and the upper end is connected to the surface 4b at the center in the left-right direction of the panel receiving surface 4b. Corresponding to the value obtained by forming a U-shaped cutout 4e, bending the piece cut out by this cutout 4e in the same direction, and adding the thickness of the vertical piece 2a of the base steel material 2 to the set dimension t It is formed by bending downward at a position that exceeds the above value.
[0020]
The contact piece 4d is in contact with the vertical piece 2a of the base steel material 2 at the tip, and when a load is applied to the panel receiving surface 4b to attach the wall panel 3 to the base steel material 2, the joint receiving metal fitting 4 is deformed by the load. It has the function to prevent. That is, even when a vertical load acts on the panel receiving surface 4b and the contact angle of the bent piece 4a with the vertical piece 2a becomes an angle other than a right angle due to this load, the contact piece 4d Since it is in contact with the vertical piece 2a, the contact angle of the bent piece 4a with respect to the vertical piece 2a can be maintained at a right angle.
[0021]
The abutting piece 4d is a U-shape whose lower end is connected to the surface 2b at a predetermined position on both sides in the left-right direction of a locking piece 4c formed at the center of the panel receiving surface 2b and whose vertical length is equal to the set dimension t. A cutout 4f is formed, and a piece cut out by the cutout 4f is bent in the same direction as the bent piece 4a.
[0022]
Accordingly, the contact piece 4d comes into contact with the vertical piece 2a of the base steel material 2 in the horizontal direction, and effectively prevents deformation of the joint receiving bracket 4 together with the bent piece 4a that makes contact with the vertical piece 2a in the vertical direction. Is possible. However, the abutting piece 4d does not necessarily need to abut against the vertical piece 2a in the horizontal direction, and prevents deformation of the joint receiving bracket 4 even when abutting in the vertical direction against the vertical piece 2a, like the bent piece 4a. Is possible.
[0023]
As shown in FIG. 4, the joint receiving bracket 4 is locked by inserting it from above the vertical piece 2a of the base steel material 2 and fitting the locking piece 4c to the vertical piece 2a. The contact piece 4d is attached to the vertical piece 2a so that the vertical piece 2a is sandwiched between the pieces 4a, 4d and the locking piece 4c.
[0024]
When the joint receiving bracket 4 is attached to the base steel member 2, the distance between the vertical piece 2a of the base steel member 2 and the panel receiving surface 4b of the joint receiving bracket 4 is equal to the set dimension t which is the dimension of the bent piece 4a. By attaching the indoor side surface 3a of the wall panel 3 in contact with the panel receiving surface 4b, the gap between the wall panel 3 and the base steel material 2 can be maintained at a preset dimension t.
[0025]
Compared to the conventional plate-shaped liner, the joint receiving bracket 4 is configured using an extremely thin plate, so that the material cost can be reduced, and the attachment to the base steel material 2 can be performed with the locking piece 4c. Since it is performed by fitting the vertical piece 2a, it is not necessary to perform a welding operation or a bonding operation, and the operation cost can be reduced.
[0026]
Further, the joint receiving metal fitting 4 is formed at the both end sides by forming a locking piece 4c to be fitted with the vertical piece 2a in the plane of the panel receiving surface 4b, as compared with a spacer formed in a conventional U shape. In the formed locking piece, the length corresponding to the dimension of the hanging allowance L × 2 with respect to the vertical piece is shortened, and the material cost can be reduced accordingly. Further, if there is a gap slightly larger than the thickness of the joint receiving metal fitting 4 on the indoor side of the vertical piece 2a, the joint receiving metal fitting 4 can be attached, and a column is arranged on the indoor side of the vertical piece 2a. Even in such a case, it can be easily attached.
[0027]
Next, joint receiving brackets 5 and 6 having a shape different from that of the joint receiving bracket 4 will be described with reference to FIG. In the joint receiving metal fitting 5 shown in FIG. 5A, a panel receiving surface 5b is formed between the bent pieces 5a formed on both sides in the left-right direction, and two locking pieces 5c are formed on the panel receiving surface 5b. One contact piece 5d is formed. That is, a contact piece 5d similar to the contact piece 4d of the joint receiving bracket 4 described above is formed at the center in the left-right direction of the panel receiving surface 5b, and the joint receiving bracket 4 is formed on both sides of the corresponding contact piece 5d. A locking piece 5c similar to the locking piece 4c is formed.
[0028]
Thus, even if two locking pieces 5c are formed on the joint receiving metal fitting 5, the joint receiving metal fitting 5 can be engaged with the vertical piece 2a of the base steel material 2 and locked. It is possible to prevent deformation of the joint receiving metal fitting 5 by bringing the contact piece 5d into contact with the vertical piece 2a.
[0029]
In short, it is sufficient that at least one of the locking piece 5c and the contact piece 5d is provided. Accordingly, a parallel notch is formed at the center of the panel receiving surface in the left-right direction with a length obtained by adding the length of the latching piece and the contact piece in the vertical direction, and the latching piece in the notch, A horizontal cut is formed at a position corresponding to the length of the contact piece, an engagement piece is formed by the upper cut piece, and an abutment piece is formed by the lower cut piece. Even a joint receiving bracket with a contact piece is attached to the vertical piece 2a of the base steel material 2 to keep the gap between the steel material 2 and the wall panel 3 at a preset size and prevent deformation of the joint receiving bracket. Is possible.
[0030]
The joint receiving metal fitting 6 shown in FIG. 6B has an engaging piece 6c and an abutting piece 6d formed in the same manner as the engaging piece 4c and the abutting piece 4d in the joint receiving metal fitting 4, The bent pieces 6 a formed on both sides in the left-right direction have a different shape from the bent pieces 4 a of the joint receiving bracket 4.
[0031]
That is, the bent piece 6a is not formed by being bent over the entire length of the joint receiving metal fitting 6 in the vertical direction, but is formed by bending only a portion of the base steel material 2 that can contact the vertical piece 2a. Even in the joint receiving bracket 6 having such a bent piece 6a, the bent piece 6a abuts over the entire length in the height direction of the vertical piece 2a when locked to the vertical piece 2a. It is possible to maintain the gap between the wall panel 3 and the wall panel 3 at a preset dimension t, and to prevent the joint receiving bracket 6 from being deformed.
[0032]
Next, the locking piece 7 having a shape different from that of the locking piece 4c in the joint receiving metal fitting 4 will be described with reference to FIG. In the figure, it is assumed that the locking piece 7 is formed on the joint receiving bracket 4 described above, and the description of the configuration other than the locking piece 7 is omitted.
[0033]
The locking piece 7 is formed by bending a piece cut out from a U-shaped notch 4e formed at the center in the left-right direction of the panel receiving surface 4b in the same direction as the bent piece 4a, and setting the dimension t and the base steel material 2 perpendicular to each other. It is formed by bending downward at a position sufficiently larger than the length including the thickness of the piece 2a. At this time, an angle formed between the locking piece 7 and the back surface of the panel receiving surface 4a is an acute angle or a right angle, and an angle at which the locking piece 7 is bent downward is an acute angle, thereby fitting with the vertical piece 2a of the locking piece 7. It is preferable to form the mating portion in a hook shape.
[0034]
In the locking piece 7 formed as described above, the degree of freedom for changing the thickness of the vertical piece 2a of the base steel material 2 is improved. For example, as the base steel material 2, L-50 × 50 × 4, L-50 × 50 Even when the angle material of standard size such as × 6 or L-65 × 65 × 5, L-65 × 65 × 6, L-65 × 65 × 8 is selectively used, the thickness of each It is possible to respond.
[0035]
【The invention's effect】
As described above in detail, in the wall panel mounting structure according to the present invention, the joint receiving bracket is provided by locking the locking piece formed by cutting out a part of the panel receiving surface to the vertical piece of the base steel material. Attaching to the base steel material, the tip of the bent piece formed on both sides in the left and right direction and the tip of the contact piece formed on the panel receiving surface are brought into contact with the base steel material, so that the panel receiving surface and the base steel material The spacing can be kept equal to the preset gap. For this reason, when the wall panel is attached in contact with the panel receiving surface, the gap between the panel and the base steel material can be maintained at a preset value.
[0036]
Further, since the joint receiving bracket is attached to the base steel material through the locking piece formed on the panel receiving surface of the metal bracket, it is not necessary to form a large gap on the indoor side of the vertical piece of the base steel material, and the column is attached to the beam. Can be easily attached without applying special processing to the base steel material.
[0037]
Further, in the joint receiving bracket according to the present invention, the locking piece is formed by cutting out at least one part of the panel receiving surface, and the dimensions of the bent pieces formed on both sides in the left-right direction are set in advance. Since the dimensions are equal to the gap between the wall panel and the base steel material, the material cost can be reduced as compared with the conventional joint receiving bracket.
[0038]
In addition, when attaching to the base steel material, the bent pieces formed on both sides in the left-right direction are not attached so as to straddle the vertical pieces, but the vertical pieces are fitted and attached by the locking pieces formed on the panel receiving surface. Therefore, even if there is no large gap on the indoor side of the base steel material, it can be easily attached.
