Description

  The present invention relates to an airtight construction auxiliary member, and more particularly to an airtight construction auxiliary member used for airtight construction around a column or airtight construction at a window corner or the like.

  In ceiling insulation and floor insulation, an airtight treatment at the top and bottom of the columns (around the columns in the ceiling and floor portions) is an important point. That is, since the pillar part at the lower end of the partition wall easily forms a gap because the pillar penetrates the moisture-proof sheet, it is necessary to perform sufficient airtight construction.

  Conventionally, as the airtight construction, for example, a method shown in FIG. 13 has been performed. In this method, an airtight construction auxiliary member including a square flange portion 51 having a square central opening and a rising wall 53 rising vertically along the edge of the central opening is used.

  The auxiliary member is provided with a separation portion 54 that extends from the outer edge of the intermediate portion of one side of the flange portion 51 to the upper edge of the rising wall 53, and is opened from there so as to surround and attach the end portion of the column 55. To get.

  After mounting on the column 55 in this way, first, a long fixing tape 56 is applied along the separating portion 54, and then straddled between the rising wall 53 in contact with the column 55 and the side surface of the column 55. Then, the fixing tape 56 is stopped, and finally, the fixing tape 56 is stuck around the flange portion 51 in the form of a cross beam to complete the operation.

  In the case of the above-mentioned conventional airtight construction auxiliary member, there is no problem if the diameter of the central opening 52 always matches the diameter of the column 55, but if it is different, or if the building material is rectangular like a beam Cannot be used. That is, the conventional airtight construction auxiliary member has a limited use and is not versatile.

  The present invention has been made in view of the above circumstances, and can be used not only for building materials having a square cross section such as a pillar, but also for building materials having a rectangular cross section such as a beam, or for airtight construction in a window corner, etc. It is an object of the present invention to provide a versatile hermetic construction assisting member that can easily and quickly carry out the construction.

  The invention according to claim 1 for solving the above-described problem comprises a flange portion having a central opening and a rising wall rising along the central opening, and the rising wall is formed from an outer edge of the flange portion. It is an airtight construction auxiliary member that is provided with one separating portion that reaches the upper end, and is formed with ridges extending from the outer edge of the flange portion to the upper end of the rising wall at equal angles from the separating portion. .

  Preferably, the flange portion and the central opening are formed in a square shape, and a V-cut is formed at one or both ends of the ridge to assist in cutting. Moreover, it is preferable to form the tape guideline which shows the sticking position of a tape in the said flange part, and the said tape guideline can be made into a protruding item | line in that case. Furthermore, it is preferable that the rising wall is a tapered surface whose upper side is narrowed.

  Since the airtight construction assisting member according to the present invention has the above-described configuration, it is possible to divide the entire member into two or four parts, as well as a column having a size corresponding to the central opening thereof, thereby increasing the diameter of the column and the beam having a rectangular cross section. In addition, it is possible to use it by dividing it into four parts, such as window corners, etc., and using it corresponding to various places that require airtight construction auxiliary members. is there.

  In addition, the provision of ridges makes it easy to divide the main part on site, and the provision of tape guidelines can provide a guideline for the location of the fixing tape, making the tape application work quick and easy. There is an effect that can be done accurately.

  The structure of the airtight construction auxiliary member according to the present invention and the usage thereof will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of an airtight construction auxiliary member according to the present invention. This member has a flange portion 1 having a central opening 2 and a rise that rises, for example, by about 30 mm along the central opening 2. It consists of a wall 3. Usually, the flange portion 1 and the rising wall 3 are integrally formed of a polypropylene sheet having a thickness of about 0.3 mm.

  Usually, the flange portion 1 has a square shape as illustrated, but is not limited thereto, and may be a circular shape, a hexagonal shape, or the like. The central opening 2 is a square having a size corresponding to the quadrangular prism that is the main target of use. For example, when it is used for a cylinder, it is a circular opening. Since many quadrangular prisms have a 3.5-inch square (105 mm square), in many cases, the central opening 2 is also sized accordingly.

  A separation line 4 is formed from the outer edge of the flange portion 1 to the upper end of the rising wall 3 to form a separation portion 4, and the flange portion 1 and the rising wall 3 are separated from each other at that portion. Further, a ridge (groove as viewed from the back side) 5 extending from the outer end edge of the flange portion 1 to the upper end of the rising wall 3 is formed at an equal angle from the separating portion 4 (typically 90 degrees).

  The ridges 5 are provided to facilitate the cutting work of this member on site. In other words, this member is divided and used depending on the application as will be described later, and the division is performed by applying a ruler along the line to be cut in the field and cutting with a cutter. become. Therefore, the ridge 5 that indicates the cutting line is formed in advance, and the cutter is moved along the groove on the back side thereof, so that the cutting operation can be easily performed without using a ruler.

  Preferably, the V-cut 6 is formed at one end or both ends of the ridge 5 (in the illustrated example, only the outer end of the flange portion 1). The V-cut 6 is provided in order to make it easy for the cutter to bite into the first protrusion (groove) 5 of the cutting head.

  More preferably, a tape guideline 7 for indicating a position where the fixing tape 10 is stuck is formed on the flange portion 1. The tape guide line 7 is a ridge which is the same as or higher than the ridge 5, and is usually formed in a square shape. The tape guideline 7 is not a ridge, but may be simply displayed as a straight line. However, the tape guideline 7 is more preferable because it also serves as a reinforcing rib.

  The rising wall 3 is preferably a tapered surface whose upper side is narrowed. For example, when the height of the rising wall 3 is 30 mm, the lower side may be 108 mm and the upper side may be 105 mm. Thus, by making the rising wall 3 a tapered surface, the degree of adhesion to the column 11 can be increased.

  A method of using the main member having the above configuration will be described. First, the usage method shown in FIGS. 4 to 6 will be described. This use example is an example used to form an airtight layer around the pillars in the ceiling part and the floor part of the pillar 11, and in this case, first, the flange part 1 and the rising wall 3 are opened from the separation part 4, The column 11 is accommodated in the central opening 2, and the rising wall 3 is applied to the side surface of the column 11 (FIG. 4).

  Next, the fixing tape 10 is applied so as to completely cover the joint of the separation part 4 (FIG. 5). The fixing tape 10 is pasted long so as to extend from the side surface of the pillar 11 to the floor surface (ceiling surface) through the separation portion 4. Then, the fixing tape 10 is wound so that one half of the width direction is in contact with the rising wall 3 and the other half is in contact with the side surface of the column 11, and finally the fixing tape 10 is wound along the outside of each tape guideline 7. Then, both ends come out of the flange portion 1 and reach the floor surface (ceiling surface) so as to be stuck in a cross-beam shape, thereby completing the fixing of the member (FIG. 6).

  Next, a method of using the case (FIGS. 7 to 9) in which the short side length is used for the beam 12 having a rectangular cross section matching the central opening 2 will be described. In this case, this member is divided into two parts by cutting the ridge 5 on the opposite side of the separation part 4 (FIG. 7). Then, each divided piece is applied to the upper edge and the lower edge of the beam 12 (FIG. 8), and the fixing tape 10 is applied so as to straddle the rising wall 3 and the beam 12, respectively. Then, the fixing tape 10 is pasted so as to straddle the wall surface of the flange portion 1 (FIG. 9), and the fixing of this member is completed.

  Further, the usage method shown in FIGS. 10 to 12 will be described. This usage example is an example in which each member 5 is cut into four equal parts by cutting the ridges 5 and used for protruding corners such as pillars and window corners having a larger diameter than the central opening 2. In this case, the cut member is applied to each corner of the large-diameter column and fixed with the fixing tape 10 according to the example shown in FIG. Further, the cut member is turned over, the corner portion constituted by the rising wall 3 is applied to the corner of the window (FIG. 11), and the flange portion 1 is taped (FIG. 12).

  As described above, the airtight construction auxiliary member according to the present invention can be used for various purposes, and enables airtight construction to be performed quickly and accurately.
