The spring member 77 moves the fixing pin 80b closer to the locking pin 78b. The slide bar 75 is biased.
[0007]
Here, the spring member 77 made of a shape memory alloy exerts an elastic force (contraction force) when the outside air temperature is high, such as in spring or summer, and the elastic force at that time exerts the elastic force of the spring 76. When the outside air temperature is low, elastic deformation is not exhibited due to plastic deformation, and the contraction force of the spring 76 is set to exceed the urging force of the spring member 77.
That is, in the building module article 70 shown in FIG. 7, when the outside air temperature is high, the contraction force of the spring member 77 exceeds the contraction force of the spring 76, and the slide bar 75 is in the retracted position.

[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a building module article for ventilation control according to the present invention and an embodiment of a ventilation control device using the building module article for ventilation control will be described. 1, 2, and 3 are a perspective view, a side view, and a cross-sectional view illustrating a configuration of an embodiment of a building module article for ventilation control.
As shown in FIGS. 1 to 3, the ventilation control building module product 70 of the present embodiment has rectangular mounting plates 71 and 72 and a mounting member, similarly to the conventional ventilation control building module product 70 shown in FIG. 7. Guide plates 73 and 74 for supporting the plates 71 and 72 vertically in parallel with each other; a slide bar 75 inserted into a cylindrical portion surrounded by the mounting plates 71 and 72 and the guide plates 73 and 74; A spring 76 that connects the bar 75 and the mounting plate 72 and a spring member 77 made of a shape memory alloy are provided.
[0016]
As shown in FIG. 3, a spring 76 and a spring member 77 are arranged in parallel to the guide plates 73 and 74 at opposing positions with a slide bar 75 interposed therebetween, and the spring 76 is provided on one end of the mounting plate 72. The spring member 77 is suspended between a stop pin 78a and a fixing pin 80a fixed to one side surface on the rear end side of the slide bar 75, and a spring pin 77 is provided on the other end of the mounting plate 72. 78b and a fixing pin 80b fixed to the other side surface on the front end side of the slide bar 75.
[0017]
The spring 76 is simply curled at the end in an arc shape, and is attached by locking the end of the spring 76 to a locking pin 78a and a fixing pin 80a, whereas the spring member 77 is formed by shaping a plate material into a hook shape. The hooks 82a and 82b are locked to the ends of the coil and attached to the locking pin 78b and the fixing pin 80b.
Similar to the conventional ventilation control building module article 70, in the ventilation control building module article 70 of the present embodiment, the spring 76 is formed as a contraction spring, and the spring member 77 has an elastic force (contraction force) when the outside air temperature is high. ) Is exerted, and when the outside air temperature is low, it is set so that it is plastically deformed and the elastic force is not exerted.
[0018]
The distance between the locking pin 78a for attaching the spring 76 and the fixing pin 80a and the distance between the locking pin 78b for mounting the spring member 77 and the fixing pin 80b are determined when the outside air temperature is a temperature at which the spring member 77 exerts a complete elastic force. In addition, the elastic force (shrinkage force) of the spring member 77 exceeds the elastic force (shrinkage force) of the spring 76, and the slide bar 75 is set to the retracted position. When the outside air temperature is between the high temperature and the low temperature, the slide bar 75 is adjusted to the intermediate position between the projecting position and the retracted position by the difference between the urging force of the spring 76 and the urging force of the spring member 77. ing. 73a and 74a are long holes formed by cutting out the ends of the guide plates 73 and 74, the fixing pins 80a and 80b are movable in the long holes 73a and 74a, respectively, and the slide bar 75 is connected to the long holes 73a. , 74a in the longitudinal direction.
[0019]
The characteristic configuration of the ventilation control building module product 70 of the present embodiment is such that when the ventilation control building module product is exposed to a high temperature due to a fire or the like at a mounting portion for attaching the spring member 77 to the locking pin 78b. The hook 82a that locks the spring member 77 to the locking pin 78b is removed from the locking pin 78b, and a safety mechanism is provided to prevent the elastic force of the spring member 77 from acting on the slide bar 75.
[0020]
In the present embodiment, a spring plate 90 obtained by bending a plate-shaped shape memory alloy into a U-shape is used as a safety mechanism for releasing the spring member 77 from the locking pin 78b. By setting so that the force is exerted, the spring member 77 is detached from the locking pin 78b by utilizing the elastic force of the spring plate 90. Specifically, as shown in FIG. 2, one end of the spring plate 90 is fixed to the lower surface of the longitudinal end of the mounting plate 72, and the other end of the spring plate 90 is fixed to the locking pin 78b. The hook 82a is arranged so as to contact the lower surface of the hook 82a.
[0021]
The spring plate 90 is formed of a shape memory alloy that exhibits elasticity at high temperatures, and is plastically deformed into a U-shape at a normal temperature to maintain the U-shape. The hook 82a is extended so as to extend in a straight line, and the hook 82a, which is locked to the locking pin 78b by the extension force, is detached from the locking pin 78b. As described above, the spring member 77 is locked to the locking pin 78b via the hook 82a formed by a plate-shaped member. As shown in FIG. 2, the hook 82a is moved in the axial direction of the locking pin 78b. The other end of the spring plate 90 is brought into contact with the lower surface of the hook 82a, and the other end of the spring plate 90 jumps up the hook 82a. The hook 82a can be securely removed from the locking pin 78b.
[0022]
It is preferable that a stopper or the like is not provided at the tip of the locking pin 78b so that the hook 82a can be easily pulled out from the locking pin 78b, and the locking pin 78b is formed in a simple round bar shape. Note that there is no problem to the extent that a shallow groove is provided on the outer peripheral surface of the locking pin 78b so that the hook 82a does not shift on the locking pin 78b. The spring plate 90 has one end fixed to the lower surface of the mounting plate 72 and bent in a U-shape so as not to interfere with the end of the mounting plate 72 so as to contact the lower surface of the hook 82a. The shape of the plate 90 is not limited to a U-shape.
[0023]
FIG. 4 shows a state in which the spring plate 90 is exposed to a high temperature and the hook 82a is removed from the locking pin 78b by pulling it out. The spring plate 90 extends straight from the U-shaped state, and the hook 82a is removed by the extension force of the spring plate 90. The spring member 77 contracts and moves toward the fixing pin 80b. When the hook 82a is removed from the locking pin 78b, the elastic force of only the spring 76 acts on the slide bar 75, and the slide bar 75 instantaneously moves to the projecting position.
In this state where the slide bar 75 is in the protruding position, if the ventilation control unit is set so that the opening for taking in the outside air is closed, the outside ventilation layer and the inside ventilation layer are shut off from the outside air, Safety can be ensured. Note that the spring plate 90 of the present embodiment is set so that the elastic force is exerted when the temperature reaches 80 ° C., and is set so that the spring plate 90 does not normally operate.
[0024]
In the building module article 70 for ventilation control shown in FIGS. 1 to 4, when the outside air temperature is high, the operation section of the slide bar 75 is at the retracted position, and when the outside air temperature is low, the operation section of the slide bar 75 projects. However, the construction module article 70 for ventilation control according to the present embodiment simply reverses the mounting position (insertion direction) of the slide bar 75, and when the outside air temperature is high, the action portion of the slide bar 75 Is in the protruding position, and when the outside air temperature is low, the action portion of the slide bar 75 can be in the retracted position.
[0025]
FIG. 5 shows an example in which the insertion direction of the slide bar 75 is reversed from the above example. Fixing pins 80a and 80b are fixed to one and the other side surfaces of the slide bar 75 on the rear end side and the front end side (operating end side), respectively. The mounting plate 72 corresponds to the fixing pins 80a and 80b. The locking pins 78a and 78b are provided at a predetermined distance from each other, and the slide bar 75 is formed in a tubular shape having a rectangular cross section and formed by the mounting plates 71 and 72 and the guide plates 73 and 74. The insertion direction of the slide bar 75 can be exchanged by being insertable into the portion from either side. When it is necessary to adjust the elastic force between the spring 76 and the spring member 77 when the direction of insertion of the slide bar 75 is changed, the locking pins 78a, 78b are attached to the mounting plate 72 on which the locking pins 78a, 78b are mounted. A plurality of locking holes for selecting the locking position may be provided.
[0026]
The building module article 70 for ventilation control according to the present embodiment can be easily mass-produced because the mounting plates 71, 72 and the guide plates 73, 74 are integrally formed by extrusion molding with aluminum. There is an advantage that the dual use is possible by changing. In this embodiment, the slide bar 75 is also made of aluminum.
[0027]
FIG. 6 is an example in which the above-described building module article for ventilation control 70 is applied to a ventilation control device 50 for controlling the ventilation from under the floor to the internal ventilation layer 20. The ventilation control device 50 is configured such that a ventilation pipe 52 having a U-shaped cross section is fixed on a base so that a shielding plate 53 is slidably mounted on an upper surface inside the ventilation pipe 52. Vent holes 54 are provided at predetermined intervals on the upper surface of the vent pipe 52, and vent holes 53 a are provided in the shield plate 53 in the same shape and at the same interval as the vent holes 54. In addition, in this ventilation control device 50, the ventilation amount to the internal ventilation layer 20 can be appropriately set by changing the size and the number of the ventilation holes 54.
[0028]
The building module article 70 for ventilation control is provided with the shielding plate 53 engaged with a sliding bar 75 so that the shielding plate 53 can be slid in the longitudinal direction. When the outside temperature is high in summer or the like, the sliding bar 75 projects. When the outside air under the floor is introduced into the internal ventilation layer 20 through the ventilation hole 54 and the outside air temperature becomes low in winter or the like, the spring 76 is attached. When the force exceeds the urging force of the spring member 77, the slide bar 75 is moved to the retracted position (the position where the shielding plate 53 shields the ventilation opening 54), and the outside air is controlled so as not to enter the internal ventilation layer 20.
[0029]
In the ventilation control device 50, when the building module article 70 for ventilation control is exposed to a high temperature due to a fire or the like, the spring member 77 of the building module article 70 for ventilation control comes off from the locking pin 78b, and only the urging force of the spring 76 is applied to the slide bar. Acting on 75, the shielding plate 53 moves to a position where the ventilation hole 54 is shielded by the shielding plate 53, and the internal ventilation layer 20 is closed from under the floor. Thereby, introduction of outside air into the internal ventilation layer 20 is prevented, and it is possible to prevent fire from entering the inside through the internal ventilation layer 20.
[0030]
The above-described ventilation control device 50 is a device for controlling the ventilation at the communicating portion between the underfloor portion and the internal ventilation layer 20, but the ventilation control device 42 for controlling the ventilation at the eaves portion of the building shown in FIG. Exactly the same can be applied. Also in this case, by providing a safety mechanism in the building module article 70 for ventilation control, it is possible to prevent fire from entering from the eaves and improve safety. The ventilation control device 30 provided at the drain of the building and the ventilation control device 60 provided at the back of the cabin shown in FIG. 9 similarly control ventilation using the ventilation control building module article 70 provided with a safety mechanism. It can be configured.
[0031]
As a method of using the building module article 70 for ventilation control, as shown in FIG. 6, for example, a shielding plate is directly connected to the slide bar 75, and the shielding plate advances and retreats in parallel with the pushing operation of the slide bar 75. In addition to the setting method, the shield plate is supported so as to rotate, and the slide bar 75 is rotated to open and close the shield plate. In addition, various methods such as a method of opening and closing the shielding plate by rotating the axis of the shielding plate with the slide bar 75 can be adopted.
[0032]
In a ventilation control device using the ventilation control building module article 70 provided with these safety mechanisms, the ventilation control apparatus is heated to a high temperature due to a fire or the like, and the safety mechanism of the ventilation control building module article 70 operates to operate the slide bar. By designing so that the ventilation port of the ventilation control device is closed when the urging force of the spring 76 acts on 75, a more secure ventilation control device can be obtained. Further, even though the usage of the ventilation module building module product 70 differs in each ventilation control device, it is useful in that it can be generally used in one form by adjusting the projecting direction of the slide bar 75 or the like. is there.
Thus, by providing the ventilation and heat insulating structure, it is possible to appropriately control the ventilation in the building, to provide a cool living environment in summer and a warm living environment in winter, and to appropriately extend the life of building materials and the like. In addition, it is possible to provide a highly safe building structure.
