Description

TECHNICAL FIELD The present invention relates to a structure for attaching a panel to a skeleton such as a pair of building structures spaced apart from each other so as to be angularly displaceable by a hinge.

2. Description of the Related Art Conventionally, there is a configuration in which a frame such as a pair of building structures adjacent to each other with a space therebetween is provided with a panel that can be angularly displaced by a hinge in order to prevent intrusion of wind and rain within the space, Even if the distance between the frames changes due to an earthquake or ground subsidence, each panel can be displaced by angular displacement or sliding according to the change in the distance.

Problems to be Solved by the Invention In such a prior art, the displacement amount of each body is large,
If there is a large change in the spacing, each panel may come into contact with the wall surface of the skeleton. Therefore, the displacement amount of each skeleton can be made as large as possible without the panel contacting the wall surface. Desirably, such a stretchable exterior structure was desired.

Therefore, an object of the present invention is to provide a stretchable exterior that allows the panel, which is angularly displaced when the space is changed, to close the space without interfering with the wall surface of the frame and to allow a large allowable displacement amount of each frame. Is to provide the structure.

Means for Solving the Problems According to the present invention, a pair of skeletons spaced apart from each other are provided with mounting members on respective wall surfaces of the skeletons, and each mounting member has a pair of movable members by a hinge. One end of each panel is connected, the other end of each movable panel is connected by another hinge, and the axes of the hinges are parallel to each other.

In the present invention, the mounting member may have a first inner cover body projecting inward from a hinge provided on one end side of the movable panel and projecting into the space outward from the hinge. A first outer cover body and a stopper that is disposed so as to project from the wall surface and that prevents angular displacement of the movable panel at a position separated by a distance from the wall surface are provided. A second inner cover body arranged so as to partially overlap the first inner cover body and a second outer cover body arranged so as to partially overlap the first outer cover body in a substantially vertical direction; A seal member is provided between the first inner cover body and the second inner cover body and between the first outer cover body and the second outer cover body, respectively.

According to the present invention, the axes of the hinge connecting one end of the movable panel and the mounting member and the other hinge connecting the other end of each movable panel are made parallel to each other. Even if the frame is displaced and the distance is changed, the panels can be smoothly angularly displaced about the axis of each hinge provided in the mounting member while the panels are still connected, and the displacement can be allowed. Since such a movable panel is mounted on the mounting member, even if each movable panel is angularly displaced and becomes parallel to the wall surface thereof, there is no risk of contact with the wall surface. Moreover, the length of each movable panel and the amount of protrusion of the mounting member from the wall surface are set so that the relative displacement amount of each frame becomes the maximum displacement amount in the state where the movable panel is parallel to the wall surface in this way. By doing so, it is possible to reliably prevent the movable panel from coming into contact with the wall surface. Further, since the movable panel can be angularly displaced until the movable panel becomes parallel to the wall surface, the allowable displacement amount of each skeleton can be made larger with respect to the constant interval.

According to the present invention, the mounting member is provided with the first inner cover body and the first outer cover body, and the movable panel is provided with the second inner cover body.
An inner cover body and a second outer cover body are provided. Sealing members are provided between the first inner cover body and the second inner cover body and between the first outer cover body and the second outer cover body, respectively, so that the respective skeletons are relatively displaced. Also, the movable panel can be angularly displaced around the axis of a hinge provided at one end according to the displacement amount, and even if the movable panel is angularly displaced, the movable panel is attached. The space between the wall surface and the movable panel can be closed in an airtight state. Further, since the mounting member is provided with the stopper, it is possible to prevent the movable panel from coming into contact with the wall surface when the movable panel is angularly displaced.

13 is a front view seen from the outside 13 side of FIG. The horizontal frame member 50 arranged at the vertically upper end portion of the movable panel 6a includes the cover plate 5
It is fixed in a state of being sandwiched by 1, 52, and a vent hole 53 is formed in the cover plate 51 on the outer 13 side. This vent
On the inner surface 54 of the horizontal frame member 50 facing the 53, the movable panel 6a is provided in the frame 2a.
In the state of being attached to, the inner surface is inclined downward from the inner side 14 toward the outer side 13 and is connected to the ventilation hole 53.
Vents 55, 56 are formed above the inner surface 54,
A rising piece 57 is formed near the vent hole 56 on the upper side. The packing 58 abuts on the rising piece 57, and the packing 58
Is fitted to a hanging piece 60 formed on a horizontal frame member 59 of another movable panel 6a1 arranged above the movable panel 6a. The horizontal frame member 59 has a hanging piece 61 formed on the inner side 14 side of the hanging piece 60, and the packing 62 contacts the hanging piece 61. The packing 62 is formed on the rising piece 63 of the horizontal frame member 50, and the rising piece 63 is more internal than the rising piece 57.
It is formed so as to project upward in the side direction. Therefore the movable panel 6a
The packing 58 of 1 is arranged below the packing 62 of the movable panel 6a on the outside 13 side, thereby preventing wind and rain from entering from the outside 13 side. Also, these packings 58,62
Outside air is introduced into the space 64 between the frame members 50, 59 closed by the air through the ventilation holes 53, 55, 56, whereby the outside air pressure and the pressure in the space 64 are the same.

The sealing function can be maintained airtightly over the entire length.

FIG. 9 is a diagram for explaining the operation of the movable panels 6a and 6b corresponding to the change in the distance L at the interval 1. In the figure, the case where the wall surfaces 40a, 40b facing each other of the skeletons 2a, 2b are parallel, and the straight line 10 connecting the respective axial lines 1, l2 of the hinges 5a, 5b is perpendicular to the wall surfaces 40a, 40b will be described. . First,
In the state where the wall surfaces 40a, 40b of the respective skeletons 2a, 2b are separated by the distance L, the hinges 5a, 5b are arranged at the points P1, P2, and the hinge 5c is indicated by the point P3. Radius R centered on point P2
Of the area surrounded by the virtual circle S1 of, the area ΔS (indicated by diagonal lines) sandwiched by the arcs S2 centered on the point P3 on the straight line 11 parallel to the wall surface 40a and having a radius of the length L2
When the right-angled triangle that connects the points P1, P2, and P3 is considered with the area excluding ∘ as the allowable movable area, the first expression holds.

(L1 + L2 + R) (L2-L1 + R) = (L3 + R) ² (1) In this first equation, the distance L3 is obtained by the second equation.

L3 = L−R−D (2) In the second equation, the distance D is obtained by the third equation.

D = H1 + H2 (3) In these first to third equations, the radius R is preset according to the amount of displacement due to an earthquake or ground subsidence,
For example, 450mm is selected. Further, the distance L is a distance between the skeletons 2a and 2b which are building structures, and is selected to be L = 950 mm, for example. Substituting these R = 450 mm and L = 950 mm into the first and second equations yields the sixth and seventh equations.

(L1 + L2 + 450) (L2-L1 + 450) = (L3 + 450) ² (6) L3 = 500-D (7) Next, assuming that the movable panel 6b is parallel to the wall surface 2b, the point P1, When we consider a right-angled triangle surrounded by P21 and P31, Pythagoras' theorem establishes the eighth equation.

L1 ² = L2 ² + L3 ² (8) Since the distances H1 and H2 have specific dimensions as known quantities, the unknown quantity D is obtained by the third equation. In this way, the distance L3 is obtained by substituting the obtained D value into the seventh equation. By substituting this distance L3 into the sixth equation, the sixth equation is a linear equation in which the distances L1 and L2 are unknown quantities. Then, by substituting the D value into the eighth equation, a simultaneous equation with the distances L1 and L2 as unknown quantities can be obtained. Distances L1 and L obtained by solving such simultaneous equations
2 is obtained by substituting concrete numerical values into the above-mentioned formulas 6 and 8 for convenience, and by lines M1 and M2 corresponding to the distances L1 and L2 shown in FIG. 10, respectively. Also,
By substituting a concrete numerical value into the formula 8, line M3
Get. In order for the straight line connecting the points P1, P2, P3 from these lines M1 to M3 to be a right triangle, the lines M2 and M3
The D value and the distance L2 at the point Q1 where and intersect can be obtained, the distance L1 then being indicated by the point Q2 on the line M1.

Summarizing the above results, the range in which point P2 can move is R
= 450mm, D1 = H1 + H2 = 170.5m, H1-H2
= 85.25mm, and the distance L1 = 658.9mm, L2 = 570.7mm. By setting the size and shape of each member based on such distance, the allowable movement amount R = 450mm
Within the imaginary circle S1 (excluding the area ΔS), relative displacement of the skeletons 2a and 2b can be allowed without the point P3 contacting the wall surfaces 40a and 40b.

In the above description with reference to FIG. 9, assuming that the point P1 is stationary, the movable panel 6a is moved to the wall surface 4a when the point P2 moves.
Although the case where the point P1 is parallel to the above is described, it can be similarly obtained when the point P1 moves while the point P2 is stationary.

FIG. 11 is a horizontal sectional view of a part of a further embodiment of the present invention. The movable panels 6a and 6b are a pair of hinges 150c1 and 150.
Connected by c2. The hinge pieces 151 and 152 formed on both sides of each of the hinges 150c1 and 150c2 are biased by a spring 153 so that the movable panels 6a and 6b come close to each other. Each of the hinges 150c1 and 150c2 and the spring 153 is covered from both sides by water stop plates 12c1 and 12c2, and cover sheets 10c and 11c are provided outside the water stop plates 12c1 and 12c2. It should be noted that both hinges 150c1 and 150c2 may be slidable by providing an elongated hole in the mounting portion so that they can move up and down. Two hinges like this 150c1,150c
By connecting each movable panel 6a, 6b by 2,
As shown in FIG. 12 (1), in the embodiment shown in FIGS. 1 to 10, when the hinge 5b is displaced within the range shown by the imaginary circle S2, the hinge 5c that connects the movable panels 6a and 6b to each other. Touches the skeleton 2b as indicated by reference numeral 5c1, and the range thereof occurs in the area ΔS1 shown by hatching. This means that, as shown in FIG. 12 (2), when the skeleton 2a is displaced and the hinge 5a is displaced within the range indicated by the imaginary circle S3, the hinge 5c is also formed in the hatched area ΔS2.
Contacts the body 2b. That is, each hinge 5c is attached to the frame 2a, 2b
There will be regions ΔS1 and ΔS2 that are in contact with at least one of the two. An inscribed circle S inscribed in these areas ΔS1, ΔS2
In 4, S5, since the hinge 5c can freely move without contacting the respective skeletons 2a and 2b, the movable panels 6a and 6b are allowed without contacting the respective skeletons 2a and 2b. The amount of displacement of each of the skeletons 2a and 2b that can be performed is limited. Therefore, as shown in FIG.
By providing a pair of hinges 150c1 and 150c2 having (= L1-L2) and forming four axes, the shaded areas ΔS1 and ΔS2 shown in FIGS. 12 (1) and 12 (2) are eliminated. be able to. However, in the operation by the four axes, the movement of each movable panel 6a, 6b is restricted by a spring or the like to prevent rattling when vibrating by wind or the like, and each movable panel 6a, 6b is prevented.
The hinges 5a, 5b arranged at the base of the are provided with stoppers, etc., to ensure a predetermined movement.

FIG. 13 is an enlarged horizontal cross-sectional view showing the vicinity of the hinge 5a according to still another embodiment of the present invention. The mounting member 161 fixed to the frame 2 has a protrusion projecting into the space more than the wall surface 40a. Piece
162 is formed, and mounting pieces 163 and 164 are integrally formed on both sides in the vertical direction of the projecting piece 162 in FIG. The protrusion 162
Project inwardly of the mounting pieces 163 and 164 on both sides thereof, and a stopper 165 is provided near the tip of the bolt 166.
And fixed by nut 167. The hinge piece 168 of the hinge 5a is sandwiched between the stopper 165 and the protruding piece 162, and the hinge 5a is fixed to the protruding piece 162 together with the stopper 165. The stopper 165 has a contact surface 169 substantially parallel to the wall surface 40a, and this contact surface 169 is the wall surface 40a.
Therefore, when the movable panel 6a is parallel to the wall surface 40a, the movable panel 6a is positioned with respect to the protrusion 162 with a predetermined distance S1 so as not to contact the wall surface 40a. This distance S1 is selected to be equal to the distance H1 to the central axis 1 of the hinge 5a in the direction perpendicular to the wall surface 40a. The other hinge piece 170 of the hinge 5a is fixed to the one end 7a of the movable panel 6a by a bolt 171 and a nut 172.

In this manner, with the movable panel 6a attached to the attachment member 161 via the hinge 5a, the fitting groove 173 formed in the attachment piece 163 has one end of a water stop plate 174 made of vinyl chloride, for example. Part is locked and the other end is a fitting groove 17 formed near the one end 7a by the movable panel 6a.
Fitted in 5. A fitting groove 176 is formed in the mounting piece 164, and one end of a water blocking plate 177 is fitted in the fitting groove 176. The other end of the water stop plate 177 is fitted into a fitting groove 178 formed near the one end 7a of the movable panel 6a. In this way, the water stop plates 174 and 177 are attached to the inner side (the lower side in FIG. 13) and the outer side (the upper side in FIG. 13) of the hinge 5a, respectively. As described above, since the pair of water blocking plates 174 and 177 can cover the portion in which a relatively easy gap is formed between the mounting member 161 and the movable panel 6a, which are connected to each other via the hinge 5a, the airtightness and the watertightness can be ensured. You can get sex. Moreover, since the wind and rain do not enter the space sandwiched between the water stop plates 174 and 177, it is possible to minimize the occurrence of corrosion, and when the movable panel 6a is angularly displaced, the squeaking noise of the hinge 5a, etc. There is no danger of this occurring.

A first inner cover body 180 is attached to the mounting piece 163 by a bolt 181.
The seal member 182 made of a material such as neoprene sponge is fixed to the free end portion of the seal member using, for example, an adhesive. Further, the first outer cover body 183 is fixed to the mounting piece 164 by a bolt 184. These cover bodies 180, 183 are made of aluminum and are thinly formed so as to have flexibility and elasticity, and their thickness is, for example, about 15 mm. Further, at one end 7a of the movable panel 6a, the edge members 185, 18 are provided on both sides in the thickness direction.
6 are attached with bolts 187,188 and these edgings 18

95 is fixed by using, for example, an adhesive. The cover bodies 193 and 194 are made of aluminum, and the thickness thereof is selected thin so as to have flexibility and elasticity, and is about 1.5 mm, for example. In this way each cover body 1
80, 183, 193, and 194 are flexible and elastic, so that the sealing member 182 and the water blocking plate 193 are elastically abutted against each other, and the water blocking plate 183 and the sealing member 195 are elastically elastic from each other. Are in contact with each other. With such a configuration, the watertightness and airtightness can be further improved. Moreover, even if the movable panel 6a is angularly displaced in the direction of the arrow D1a, the seal member 195 remains elastically in contact with the water stop plate 183 and the imaginary line 19 remains.
Movable panel 6 that can slide to the position indicated by 6
In the state where a is parallel to the wall surface 40a, the contact surface 169 of the stopper 165 contacts the one end portion 7a, which causes the movable panel 6 to move.
The angular displacement of a in the direction of the arrow D1a is prevented at a position separated by a distance from the wall surface 40a. Therefore, there is no possibility that the movable panel 6a comes into contact with the wall surface 40a of the body 2. Further, when the movable panel 6a is angularly displaced in the direction of the arrow D2a, the free end portion of the second inner cover body 193 is arranged at the position indicated by the imaginary line 197. In this state, the inner side of the cover body 193, That is, the lower surface of FIG. 13 is in surface contact with the seal member 182. Therefore, the arrow D1a on the movable panel 6a
Direction or the angular displacement in the direction of the arrow D2a, at least one of the seal members 182 or 195 elastically abuts the cover body 193 or 183 to maintain airtightness and watertightness.

The description will be made assuming that one body 2b is displaced with respect to the other body 2a while the inner surfaces 40a, 40b of the respective bodies 2a, 2b are separated by a distance L. Distance L between each body
Is set to L = 950 mm, for example, and the hinge 5b has an initial value P0. In this state, when the skeleton 2b is displaced in the direction of approaching the skeleton 2a, the hinge 5b moves to the position P1, and the distance Lmin between the hinges 5a and 5b at this time is 330 mm. From this state, the hinge 5b is located at positions P2, P3, ..., Along the virtual circle S10.
The distance Lmax is 1230 mm at the position P6 where the hinge 5b can be moved in the order of P8 and P9 and the hinge 5b is farthest from the hinge 5a. As described above, by providing the pair of hinges 150C1 and 150C2 for connecting the movable panels 6a and 6b to each other to form a four-axis structure, the shaded area ΔS1, shown in FIG.
ΔS2 can be eliminated, and the allowable displacement of the skeleton can be further increased as compared with the case of the triaxial structure.

As described above, according to the present invention, since the movable panel is mounted on the wall surface by the mounting member, it is possible to prevent the wall surface and the movable panel from interfering with each other even if the respective frames are relatively displaced. . Moreover, since the mounting member is projected from the wall surface, the movable panel mounted on the mounting member can be angularly displaced until it becomes substantially parallel to the wall surface, which allows a larger allowable displacement amount. be able to.

According to the present invention, the mounting member is provided with the first inner cover body and the first outer cover body, and the second inner cover body and the second outer cover body are provided on one end of the movable panel. Since the seal members are provided between the first inner cover body and the second inner cover body and between the first outer cover body and the second outer cover body, respectively, watertightness and airtightness can be achieved more reliably. can do. Also, since the first and second inner cover bodies and the first and second outer cover bodies can be mounted after connecting the mounting member and the movable panel with the hinge, so-called retrofitting, the mounting work is easy and the workability is improved. It

Further, since the mounting member is provided with a stopper at a position projecting from the wall surface, even if the movable panel is largely angularly displaced when each frame is abruptly displaced, the movable panel comes into contact with the wall surface and is damaged. Can be prevented.
