Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is for attaching a long exterior member horizontally or attaching an exterior member to an outer wall panel configured so as not to generate excessive stress by inclining according to the shaking of the housing at the time of the occurrence of an earthquake. The present invention relates to a mounting structure for attaching a base material.
[0002]
[Prior art]
In a building constructed by attaching multiple outer wall panels to a steel frame, it can be rotated around the mounting part when installing each outer wall panel, so that it can be placed horizontally on the upper and lower beams that make up the frame during an earthquake. When a relative displacement (sway) occurs in the direction, each outer wall panel rotates and tilts around the mounting part (locking) in response to this swing, and this locking causes excessive stress on each individual outer wall panel. Some are configured not to occur.
[0003]
On the other hand, in order to improve the design of the building, the outer wall is divided into layers in the height direction, and the color or the pattern is changed for each layer. For example, in the building 51 shown in FIG. 9, a long exterior member 53 is installed in a horizontal direction at a predetermined height portion of the outer wall 52, and the outer wall 52a below the exterior member 53 and the upper outer wall 52b Different designs are expressed.
[0004]
When the outer wall 52 has a locking structure, in order to attach the exterior member 53 to the outer wall 52, it is necessary to configure the exterior member 53 so that the attachment structure of the exterior member 53 does not hinder the locking function of the outer wall 52. For this reason, the base | substrate which has the attaching part which an edge part protrudes from the surface of an outer wall panel is fixed to the pillar and beam which comprise the housing of the building 51, and the exterior member 53 is attached to this attaching part. Therefore, the outer wall 52 having the exterior member 53 is arranged on the outside by fixing the base to the indoor housing and placing the base mounting portion through the joints of the outer wall panel on the outdoor side. And it has the structure which provided the exterior member 53 in the said attaching part.
[0005]
[Problems to be solved by the invention]
As described above, when a long exterior member is attached to the surface of the outer wall panel in the outer wall of the locking structure, the base is configured on the indoor side of the outer wall panel and the exterior member is configured on the outdoor side of the outer wall panel. A problem arises in that the process of installing the panel and the exterior member must be complicated due to the crossing of the installation work of the panel and the exterior member, and this problem is accompanied by a problem that costs increase.
[0006]
In particular, when the base is attached to the housing, there is a problem that there are restrictions on the installation conditions because there are restrictions on the installation location.
[0007]
An object of the present invention is to provide an exterior member mounting structure that can easily attach an exterior member or a base material to which the exterior member is attached without obstructing the locking function of the outer wall panel.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the mounting structure of the exterior member according to the present invention is horizontally long across a plurality of outer wall panels that can be locked in response to the shaking of the casing that occurs during an earthquake. An exterior member mounting structure formed by attaching the exterior member, wherein the outer wall surface of each of the plurality of outer wall panels has an interval equal to or substantially an integral multiple of the width dimension of the outer wall panel. Is fixed, and the base material for attaching the exterior member or the exterior member is rotatable to the base metal fitting without being in contact with the outer wall side surface of the plurality of outer wall panels , or to be rotatable and slidable. It is what is attached.
[0009]
In the mounting structure of the exterior member, the base metal fitting has a cross-section formed in a convex shape, and includes fixing pieces that are fixed in contact with the surface of the outer wall panel on both sides, and the exterior member in the center. Alternatively, an attachment piece for attaching a base material for attaching the exterior member is provided, and the attachment piece is provided with an attachment hole for inserting a bolt protruding from the base material for attaching the exterior member or the exterior member. It is preferable.
[0010]
In the mounting structure for the exterior member, the mounting hole is preferably formed as a long hole.
[0011]
In the mounting structure of the exterior member, the base metal fitting is disposed at an interval corresponding to the width dimension of the outer wall panel, for example, at an interval equal to the width dimension of the outer wall panel, or at an interval that is an integral multiple of the width dimension of the outer wall panel. Since the exterior member or the foundation material to which the exterior member is attached is attached to the base metal fitting, it is not necessary to perform work by placing members on the indoor side and the outdoor side of the outer wall panel. Work can be carried out as exterior work after the outer wall panel mounting process. For this reason, process management becomes easy.
[0012]
In addition, since the base metal fitting, exterior material, or base material is arranged on the outer surface side of the outer wall panel, it is not necessary to consider interference with other members attached to the housing, and the degree of freedom of the mounting position of the base metal fixture or other members Will improve.
[0013]

FIG. 7 is a view for explaining the relationship between the exterior member and the base metal fitting accompanying the locking of the outer wall panel. FIG. 8 is a view for explaining the relationship between the exterior member and the base metal fitting accompanying the locking of the outer wall panel.
[0014]
The mounting structure of the exterior member according to the present invention is the locking of the exterior wall panel that constitutes the exterior wall when attaching the exterior member such as the waist difference or the base material for attaching the exterior member that is horizontally attached to the exterior wall of the locking structure. The degree of freedom of the installation position is improved without hindering the function. In the embodiments described below, an exterior member is attached to the outer wall panel. However, even when a base material for attaching the exterior member to the outer wall panel is attached, it is possible to adopt a structure substantially the same as that of the present embodiment.
[0015]
As shown in FIG. 1 and FIG. 2, the outer wall A is configured by attaching a plurality of outer wall panels 1 to a housing of a building (not shown) so as to be lockable, and corresponds to the width of the outer wall panel 1 on the surface of the outer wall panel 1. A plurality of base metal fittings 2 are arranged at fixed intervals and fixed by a fixture 3, and a long exterior member 4 is attached horizontally to the base metal fixture 2 or is shown for attaching an exterior member. The base material which does not do is attached.
[0016]
The exterior member 4 is attached so as to be rotatable relative to the base metal fitting 2 or to be rotatable and slidable. Accordingly, the outer wall A is formed with a parallelogram whose joint point is rotatable by the outer wall panel 1 and the exterior member 4, and the outer wall panel 1 is rotated according to the horizontal force acting during an earthquake or the like. When locked, the exterior member 4 moves in parallel within the surface of the outer wall A while maintaining the horizontal state as the mounting posture.
[0017]
The outer wall panel 1 is configured such that the mounting portion of the upper and lower floor beams constituting the casing can be rotated within the mounting surface, and the upper and lower floor beams are inclined in accordance with the displacement when they are relatively displaced in the horizontal direction. It is attached so that it can be locked. For this reason, even if the beams on the upper and lower floors are relatively displaced during an earthquake, for example, the force associated with the displacement does not act on the outer wall panel 1, and therefore, the destruction of the outer wall panel 1 can be prevented. Is possible.
[0018]
Each of the outer wall panels 1 is formed with a dimension based on a module dimension set in advance in the building, and the outer wall panel 1 and another adjacent outer wall panel 1 are moved relative to each other along the vertical side. Connected to form possible joints.
[0019]
The base metal fitting 2 is disposed on the outer wall A with a substantially equal interval or substantially an integral multiple of the width dimension of the outer wall panel 1 and is disposed in the horizontal direction with a substantially equal level. It is fixed to the surface by a fixture 3 such as a nail or a screw.
[0020]
The base metal fitting 2 is fixed to the outer wall panel 1 so as to be immovable, and has a function of attaching the exterior member 4 so as to be rotatable or rotatable and slidable. It is not limited. For example, examples of the base metal fitting 2 having such a function include those shown in FIGS.
[0021]
The base metal fitting 2 shown in each figure has a convex cross section, and is formed with fixing pieces 2a that are in contact with the surface of the outer wall panel 1 and fixed by the fixture 3 on both sides, and the exterior member 4 or A mounting piece 2b for attaching the base material is formed. In particular, a mounting hole 2c is formed in the mounting piece 2b of the base metal fitting 2 shown in FIG. 3, and a long hole 2d is formed in the mounting piece 2b of the base metal fitting 2 shown in FIG.
[0022]
Therefore, in the base metal fitting 2 having the mounting hole 2c, the exterior member 4 can be rotatably mounted, and the diameter of the mounting hole 2c is appropriately set with respect to the diameter of the bolt 5a described later, so that the difference between the two is possible. It is possible to slide in the direction of action of force according to. Further, in the base metal fitting 2 having the long hole 2d, the exterior member 4 can be attached so as to be rotatable and slidable along the long hole 2d.
[0023]
The exterior member 4 is a member that is formed in a long shape and is horizontally attached to the outer wall A, and exhibits design features when attached to the outer wall A. For this reason, the external appearance shape and cross-sectional shape of the exterior member 4 are not limited. Even when a base material is attached to the base metal fitting 2 in place of the exterior member 4, the shape of the base material is formed in an optimum shape corresponding to the exterior member to be attached, and is uniquely limited. It is not possible. That is, the shape of the exterior member 4 and the base material attached to the base metal fitting 2 should not be limited.
[0024]
The exterior member 4 is formed with a hole 4a through which the bolt 5a is inserted at a position facing the base metal 2, and the bolt 5a inserted through the mounting hole 2c or the long hole 2d of the base metal 2 fixed to the outer wall panel 1 is provided. The exterior member 4 is attached to the base metal fitting 2 by being inserted into 4a and fastening a nut 5b to the bolt 5a. Therefore, the exterior member 4 can be rotated with respect to the base metal fitting 2 around the bolt 5a inserted into the mounting hole 2c, or can be rotated about the bolt 5a inserted into the elongated hole 2d, and the bolt 5a can be long. It is slidably attached by moving along the hole 2d.
[0025]
In addition, when the exterior member 4 is attached to the base metal fitting 2, the exterior member 4 is configured so as not to contact the surface of the outer wall panel 1, so that unnecessary contact friction can be eliminated. The same applies to the case where a base material for attaching the exterior member to the base metal fitting 2 is attached.
[0026]
Next, the procedure for attaching the exterior member 4 to the outer wall A will be described with reference to FIG. In the figure, a plurality of outer wall panels 1 are attached in advance to a building frame with a locking structure.
[0027]
First, as shown in FIG. 2A, a plurality of base metal fittings 2 are fixed to a plurality of outer wall panels 1 constituting the outer wall A. At this time, the interval between the adjacent base metal fittings 2 is set to be approximately equal to the width dimension of the outer wall panel 1 or approximately integral multiples. In the example shown in the figure, two base metal fittings 2 are arranged with a size approximately twice the width of the outer wall panel 1 and fixed to the corresponding outer wall panel 1 by a fixture 3.
[0028]
When fixing the base metal fitting 2 to the outer wall panel 1, the bolt 5a is inserted in advance into the mounting hole 2c or the long hole 2d.
[0029]
Next, as shown in FIG. 5B, the exterior member 4 is made to face the base metal fitting 2 and a bolt 5a is inserted into the hole 4a, and a nut 5b is fastened to the bolt 5a. As shown, the exterior member 4 can be attached to the outer wall A via the base metal fitting 2.
[0030]
Next, the relationship between the exterior member 4 and the base metal fitting 2 attached to the outer wall A of the locking structure as described above will be described with reference to FIGS.
[0031]
When the horizontal force does not act on the building, that is, in the initial state in which no rocking occurs, the plurality of outer wall panels 1 constituting the outer wall A have the initial mounting state with respect to the housing as shown in FIG. The individual outer wall panels 1 are upright. In this state, for example, the distance between the most distant base metal fittings 2 is set to four times the width dimension of the outer wall panel 1 (L1).
[0032]
In addition, when the base metal fitting 2 is fixed to the outer wall panel 1 in a posture in which each side of the four circumferences is parallel to each side of the four circumferences of the outer wall panel 1, in the initial state, the relation between the base metal fitting 2 and the exterior member 4 is As shown by solid lines in FIGS. 7A and 7B, the sides of both are parallel to each other.
[0033]
When an earthquake occurs and the upper and lower beams are relatively displaced in the horizontal direction, the outer wall panel 1 is locked according to this displacement, as shown in FIG. 6B. Absorbs the force acting on the panel 1 to prevent destruction. At this time, since the exterior member 4 forms a parallelogram side together with the outer wall panel 1, the exterior member 4 translates in the plane of the outer wall A as the outer wall panel 1 is locked.
[0034]
Accordingly, the exterior member 4 maintains a horizontal posture, and the outer wall panel 1 rotates around the bolt 5 a attached to the base metal fitting 2 with respect to the exterior member 4. As shown by the dotted lines in FIGS. 7A and 7B, the base metal fitting 2 is inclined with respect to the exterior member 4 that maintains the horizontal state. That is, the exterior member 4 and the base metal fitting 2 are relatively rotated around the bolt 5a, thereby allowing the outer wall panel 1 to be locked.
[0035]
When the outer wall panel 1 is tilted by locking, the distance (L2) between the base metal fittings 2 that are farthest apart is larger than L1 corresponding to the inclination angle of the outer wall panel 1 and the number of outer wall panels 1. For this reason, with the occurrence of the difference in distance (L2−L1), a tensile stress acts on the exterior member 4, and a lateral force acts on the bolt 5a of each base metal fitting 2 in accordance with the tensile stress. .
[0036]
For example, when the exterior member 4 is assumed to be an elastic body, most of the force generated by the change in the distance of the base metal fitting 2 accompanying the locking of the outer wall panel 1 is absorbed by the elongation of the exterior member 4. For this reason, the bolts 5a of the respective base metal fittings 2 are not subjected to a lateral force due to the variation in the distance, but are not large. Contact friction between the bolts 5a and the base metal fittings 2 or the exterior member 4 It is absorbed by contact friction with the mounting piece 2b of the base metal fitting 2. Therefore, it is possible to allow the outer wall panel 1 to be locked by the relative rotation of the exterior member 4 and the support fitting 2 around the bolt 5a.
[0037]
Further, for example, when the exterior member 4 is assumed to be a rigid body, the force generated by the variation in the distance of the base metal fitting 2 accompanying the locking of the outer wall panel 1 is transverse to the bolt 5a of each base metal fixture 2 via the exterior member 4. Is transmitted as a force acting on. Then, the bolt 5a to which the force is transmitted slides in the direction of the force in the mounting hole 2c and the long hole 2d formed in the base metal fitting 2.
[0038]
For example, in the base metal 2 on the left side in FIG. 6B, the bolt 5a slides in the direction of arrow a along the long hole 2d as shown in FIG. As shown in FIG. 5B, the bolt 5a slides in the direction of arrow b along the long hole 2d. When the sliding distance of the plurality of bolts 5a becomes equal to the difference between L2 and L1 along with this sliding, the force acting in the lateral direction of these bolts 5a disappears and the position after sliding is maintained. Therefore, it is possible to allow the outer wall panel 1 to be locked by relative rotation around the bolt 5a and sliding along the long hole 5d of the bolt 5a.
[0039]
As described above, the horizontal mounting state of the exterior member 4 is maintained to lock the outer wall panel 1, the relative rotation between the exterior member 4 and the base 2 around the bolt 5 a, or the bolt 5 a of the base metal fitting 2. Can be allowed by sliding along the long hole 2d. This does not necessarily mean that all the base metal fittings 2 are constituted by a single one shown in FIG. 3 or FIG.
[0040]
That is, the base metal fitting 2 having the mounting hole 2c and the base metal fitting 2 having the long hole 2d can be mixed and arranged on the outer wall A. In this case, the exterior member 4 and the base material accompanying the locking of the outer wall panel 1 can be arranged. The relative behavior with respect to the metal fitting 2 is made non-slidable only by rotating with respect to the base metal fitting 2 having the mounting hole 2c, and the base metal fitting 2 having the long hole 2d is made to rotate and slide. With this configuration, even when the outer wall panel 1 is locked, it is possible to fix the mounting reference position on the outer wall A of the exterior member 4.
[0041]
In addition, the locking of the outer wall panel 1 is realized by reciprocatingly tilting to both sides around the vertical line. Therefore, the relative rotation of the exterior member 4 and the base metal fitting 2 around the bolt 5a as described above, and the sliding of the bolt 5a in the mounting hole 2c and the long hole 2d of the base metal fitting 2 are The reciprocating operation corresponding to the rocking cycle of the panel 1 is performed.
[0042]
In the above embodiment, the case where a plurality of base metal fittings 2 are fixed to the outer wall panel 1 and the exterior member 4 is attached to the base metal fixture 2 has been described. However, the base material of the exterior member 4 is attached to the base metal fixture 2. Even so, it is the same. In particular, the base material does not need to be long, and any base material having a function of associating the base metal fitting 2 with the exterior member may be used.
[0043]
That is, the base material may be formed in a piece shape. However, the exterior member attached to the base material is still long, and therefore, when the exterior member is attached to the base material, the structure is substantially the same as that of the above-described embodiment.
[0044]
【The invention's effect】
As described in detail above, in the exterior member mounting structure according to the present invention, the base metal fittings are arranged at intervals equal to the width dimension of the outer wall panel or at intervals of an integral multiple of the width dimension of the outer wall panel and fixed to the outer wall panel. In addition, since the long exterior member is attached to the base metal member so as to be horizontally and turnable or turnable and slidable, the outer wall panel and the exterior member are parallel to each other with a joint that can be turned relative to each other. Consists of a quadrilateral. For this reason, when the outer wall panel is locked, the exterior member can be maintained in a horizontal state regardless of the locking, and can be translated in the plane of the outer wall, and the locking of the outer wall panel is not hindered.
[0045]
Further, since the base metal is fixed only to the outer surface of the outer wall panel, the base metal can be firmly fixed to the outer wall panel, and the base metal does not fall off the surface of the outer wall panel. In addition, there is no need to work by placing members on the indoor and outdoor sides of the outer wall panel as in the past, and work can be carried out as exterior work after the outer wall panel mounting process to the housing, making process management easy It becomes. In addition, maintenance after installation is facilitated.
[0046]
In particular, it is not necessary to provide a base having a mounting portion that protrudes from the inside of the housing to the surface of the outer wall panel, and the structure of the base metal fitting to be attached to the outer wall panel is simplified corresponding to this mounting portion, and can be provided at low cost. .
[0047]
In addition, since the base metal fitting, exterior material, or base material is arranged on the outer surface side of the outer wall panel, it can be installed without considering the conditions inside the chassis including interference with other members attached to the chassis. And the freedom degree of the attachment position of another member, ie, the freedom degree of the attachment position of an exterior member, improves.
