Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a ventilation stopper to be installed in an internal space such as an outer wall of a building such as a general house or a partition wall.

[0002]

[Prior art]

 When building a house, in order to improve the heat insulation of the room, it is necessary to take ventilation measures to prevent air circulation in the space inside the wall such as the outer wall and partition wall. For this reason, conventionally, a method has been adopted in which an insulating material such as glass wool is rolled and packed at the upper end or the lower end of the inner gap of the wall to block the air flow in the wall.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional ventilation stop system, since glass wool is used, it is difficult to completely block ventilation in every space in the wall, and there is a problem that it is not possible to sufficiently prevent the formation of dew condensation in the wall. In addition, the glass wool method is also difficult in terms of construction.Since the fiber ends of the glass wool are pierced into the hand, it is disliked by the worker and the length of the space inside the wall is between the columns and studs. Since the wall and the wall formed between the studs are slightly different, the size of the glass wool must be adjusted accordingly, which makes the construction troublesome, and as a result, there is a drawback that defective construction and cut-out work are likely to occur. is there.

In view of the above points, the present invention provides a ventilation stopper that is excellent in ventilation blocking performance, has a high effect of preventing dew condensation on the wall, and is easy to install. In addition, the idea is to provide a ventilation stop that can be easily adjusted to the length of the wall.

[0005]

[Means for Solving the Problems]

 The technical means for venting of the present invention is a long material made of foamed synthetic resin with a uniform cross-section throughout, the width of which corresponds to the width of the space inside the wall, and the length is the length between the studs. The bending notch is formed at a position that matches the length and the length between the columns and studs.

Further, the material can be a polyethylene resin foam having a thickness of 5 to 30 mm.

[0007]

[Embodiment of device]

 An embodiment of a ventilation stopper of the present invention will be described with reference to the drawings. The shape of the ventilation stopper 1 is a long material having a uniform cross section, and the material is synthetic resin foam. In the examples, polyethylene resin foam is used in consideration of heat insulation, workability, bending strength, and the like. Further, the thickness D is usually about 5 to 30 mm, and in the embodiment, it is 15 mm. The width W is determined according to the width of the wall space. In a normal house construction method, the space of the wall is determined by the thickness of the pillar and becomes 105 or 120 mm, so the width W of the ventilation stop 1 is adjusted to this. Generally, in the construction of houses, the thickness of the pillars is standardized for each individual house, so it is sufficient to prepare ventilation blocks of the same width for one house.

The length of the ventilation stop 1 matches the length of the wall space. In ordinary houses, the length of the space is determined by the distance between the columns and studs. This distance is different between Kanto and Kansai areas, and because there is a difference in thickness between pillars and studs, the distance between pillars and studs and the distance between pillars are mutually different. Of different length. For example, as a first example, when a column of 105 mm square is used in the Kanto region, the distance between the studs is 425 mm and the distance between the columns and the studs is 387 mm. Further, as a second example, when a 120 mm square pillar is used in the Kansai region, the stud distance is 462 mm and the pillar-stud distance is 417 mm. Therefore, the length of the air stop 1 is set to 425 mm in the case of the example 1 and 462 mm in the case of the example 2 because it matches the length between the studs. Note that the dimensions described here are nominal dimensions, and the dimensions during actual construction will be slightly longer than this, so in the example, the length is made 5 mm longer than the dimensions described above.

The ventilation stopper 1 is provided with a notch 2 in the width direction near an end portion on one side thereof. Since the notch 2 is bent at 180 ° from here, it is preferable that the notch 2 is formed as deep as possible within a range that does not break during bending. In the embodiment, the depth of the cut is 10 mm with respect to the ventilation stopper having a thickness of 15 mm. The formation position of this notch corresponds to the length between the columns and studs. Therefore, the length M from the edge to the cut forming position is 387 mm in the case of Example 1 and 417 mm in the case of Example 2. In other words, the length N of the bent portion 3 beyond the cut 2 is 38 mm in the example 1 and 45 mm in the example 2. The dimensions here are also nominal dimensions as in the above.

Next, a method of using the ventilation stopper 1 will be described with reference to FIG. In the figure, 11 is a base, 12 is a joist, 13 is a pillar, and 14 is a stud. The thickness of the studs 14 is usually about 30 mm 2. In addition, since the pillars and studs are stood at equal intervals at the center position, there is an inevitable difference in the length of the wall formed between the pillars and studs, and the length between the studs is different.・ Slightly longer than the length between studs. On the other hand, in the ventilation stopper 1, the length L of its entire length corresponds to the length between the studs, and the length M up to the notch 2 corresponds to the length between the studs.

Therefore, if the ventilation stopper 1 is fitted between the studs in the extended state as it is, it fits snugly, and the gap between the pillars and the studs is bent by the notch 2 to prevent the air passage. If the length is shortened and then fitted, it fits snugly, and in any case, there is no gap at the end, and the space inside the wall can be completely cut off.

In the above-mentioned usage example, the ventilation stopper is attached to the lower end portion (floor position) of the wall, but it is also possible to attach the ventilation stopper to the upper end portion (ceiling position) of the wall. is there. Normally, if a ventilation stop is applied to one part of the wall, ventilation can be blocked, so the ventilation stop should be installed either above or below. In addition, since the thickness of pillars and the distance between pillars and studs are generally uniform in buildings, if one kind of ventilation stopper is prepared for one building, all It will be possible to block the ventilation of the walls.

The ventilation stopper of the present invention is not limited to the above embodiment, and can be freely modified and implemented within the range described in the scope of the utility model registration request. In particular, the material and thickness of the material for the air vent can be freely set.

[0014]

[Effect of device]

 The ventilation stopper of the present invention can be adjusted in two steps by bending it from the notch, so that it can be fitted snugly on the wall between studs and the wall between studs. The inside space can be completely ventilated. In addition, since the ventilation stopper of the present invention is a foamed synthetic resin material, it has better heat insulation than a simple sheet or a plate-shaped single solid material, and can effectively prevent dew condensation occurring in the wall space. . Furthermore, the ventilation stopper of the present invention is extremely useful in practical use, because it is easy to handle during installation, there is no risk of construction failure, and it has a simple structure and can be manufactured and provided at low cost.

According to the second aspect of the present invention, since the polyethylene resin foam is used, it is possible to inexpensively manufacture a product having sufficient air-flow blocking property and bending strength.
