Description

  The present invention relates to a heat insulating material fitting inserted between floor structure members of a wooden house.

  Conventionally, as a fixture of a heat insulating material inserted between floor structure members of a wooden house, a locking piece hung on the floor structure member, a hanging piece bent downward from an end of the locking piece, and a hanging A receiving piece that receives the heat insulating material that is bent from the lower end of the piece to the opposite side of the locking piece and is inserted between the floor structure members, and a support piece that is folded back from the tip of the receiving piece to the locking piece side. Is known (see, for example, Embodiment 3 of Patent Document 1). In addition, instead of providing a support piece folded back from the tip of the receiving piece to the locking piece side, there is also known a support piece obtained by bending the right-angled triangular protruding portions formed on both sides of the support piece downward. (For example, refer to Embodiment 1 and Patent Document 2 of Patent Document 1).

Japanese Patent No. 4988409 JP 2009-97265 A

  The support piece of the heat insulator attachment tool shown in Embodiment 3 of Patent Document 1 has a tip that abuts against the side surface of the floor structure member below the receiving piece and plays a role like a brace that supports the receiving piece. Moreover, in the case of this heat insulating material attachment tool, since it can be processed from a rectangular flat plate, it is possible to perform punching from a metal plate of a flat plate before bending without interposing a surplus region between adjacent flat plates, There is an advantage that the waste of raw materials is small.

  However, when the insulation material is strongly pressed against the receiving piece due to a deviation in the bending angle between the receiving piece and the supporting piece or a deviation in the length of the supporting piece, the bending between the receiving piece and the supporting piece is expanded or pushed. The support piece cannot be stretched strongly, and the receiving piece is pushed and bent downward. When the receiving piece is pushed and bent downward, the heat insulating material sinks, and a gap is generated between the heat insulating material and the flooring material, thereby reducing the heat insulating effect.

  In the case of the heat insulating material fitting shown in Embodiment 1 and Patent Document 2 of Patent Document 1, one side of the hanging piece side of the support piece having a right triangle shape is in contact with the side surface of the floor structure member to support the receiving piece. There is an advantage that it is easy to support the piece stably.

  However, when punching a flat plate before bending, a protruding portion having a right triangle shape must be formed on both sides of the support piece, so that an excess region is generated between adjacent flat plates. For this reason, compared with the heat insulating material fixture shown in Embodiment 3 of Patent Document 1, there is a problem that the amount of punching waste generated at the time of punching a flat plate before bending is large, and waste of raw materials is increased.

  The present invention has been made in view of the above-described conventional problems, and in a heat insulating material mounting tool having a support piece folded back from the front end of the receiving piece to the locking piece side with little waste of raw materials during production, the support piece The purpose of this is to ensure that the receiving piece can be supported.

For the above purpose, the present invention provides a locking piece hung on a floor structure member of a wooden house, a hanging piece bent downward from an end of the locking piece, and a lower end of the hanging piece. A heat insulating member having a receiving piece that receives the heat insulating material inserted between the floor structure members and is bent to the opposite side of the stop piece, and a support piece that is folded downward from the front end of the receiving piece to the locking piece side. In the material fixture,
The present invention provides a heat-insulating material mounting tool characterized in that a tip of the receiving piece has a tooth portion that protrudes toward the locking piece from the hanging piece.

Further, in the present invention, the bent portion between the hanging piece and the receiving piece is formed with a reinforcing rib projecting on the valley fold side and straddling between the hanging piece and the receiving piece,
A convex reinforcing rib is formed on the opposite side of the locking piece in the longitudinal direction of the hanging piece,
The locking piece is provided with a piercing piece and a nail hole that can be driven into the floor structure member,
The suspension piece includes the suspension piece, the receiving piece, and the support piece having the tooth portion at the tip, at both ends of the locking piece,
A notch for dividing the locking piece is provided at the center of the locking piece;
Is included as a preferred embodiment thereof.

  In addition, in this invention, the floor structure member of a wooden house means the foundation in a wooden frame construction method, a large drawing or joist, or the floor joist in a two-by-four method (2x4 construction method).

  According to the present invention, the bending angle between the receiving piece and the support piece is kept constant even when the heat insulating material is strongly pressed against the receiving piece by piercing the side surface of the floor structure member with the tooth portion provided at the tip of the receiving piece. Then, the support piece can be strutted between the receiving piece and the side surface of the floor structure member. Therefore, the receiving piece is supported by the support piece, and the heat insulating material can be supported without being bent downward, and the heat insulating material can be prevented from sinking. Moreover, the heat insulating material attachment tool of the present invention can be obtained by bending a substantially rectangular flat plate. For this reason, it is possible to perform punching from a metal plate of a flat plate before bending without interposing a surplus area between adjacent flat plates, reducing the amount of punching waste generated and reducing waste of raw materials. can do.

It is a figure which shows an example of the heat insulating material attachment tool which concerns on this invention, (a) is a top view, (b) is a front view, (c) is a bottom view, (d) is a left view. It is explanatory drawing which shows the attachment state of the heat insulating material using the heat insulating material mounting tool which concerns on this invention.

  The heat insulator attachment tool 1 shown in FIG. 1 includes a locking piece 2, a hanging piece 3, a receiving piece 4 and a support piece 5. The locking piece 2 and the drooping piece 3 connected to both ends thereof form a front downward U-shape, and both end portions are folded outward and then folded back to form a receiving piece 4 and a support piece 5. ing. The heat insulating material fitting 1 can be manufactured by punching a strip-shaped flat plate having triangular teeth 6 with acute corners at both ends from a metal plate and bending the flat plate. As the metal plate, for example, a metal plate having corrosion resistance such as an iron plate or a stainless plate subjected to a surface treatment such as a galvalume steel plate or a galvanized steel plate is preferable. The thickness is preferably about 0.3 mm to 0.5 mm in view of ease of bending, strength, cost, and the like. The width of the flat plate punched out from the metal plate is selected according to the number of the heat insulating material fittings 1 attached, the weight of the heat insulating material 7 (see FIG. 2), etc., but is generally about 10 to 20 mm, around 15 mm. Is preferred.

  The locking piece 2 is a portion that is hung on the floor structure member 8 (see FIG. 2) of the wooden house, and has a length corresponding to the width of the floor structure member 8 to be hung. When the floor structure member 8 on which the locking piece 2 is hung is a base 8a or a large pull 8b (see FIG. 2) of a wooden frame construction method, the length is generally about 90 to 120 mm. In addition, when it is hung on a floor joist (not shown) of a 2 × 4 building, the length depends on the upper surface width of the floor joist.

  A triangular piercing piece 9 protrudes downward by making an incision into the locking piece 2 and bending the inside downward. Further, a nail hole 10 is provided in the central portion of the locking piece 2. The piercing piece 9 can be driven into the floor structure member 8 (see FIG. 2), and the heat insulating material mounting tool 1 can be fixed by driving it into the floor structure member 8. In addition, since the nail hole 10 is provided together with the piercing piece 2, the fixing of the heat insulating material mounting tool 1 to the floor structure member 8 can be reinforced by driving the nail through the nail hole 10. Further, a notch 11 is formed across the central portion of the locking piece 2. This notch 11 divides the locking piece 2 so that the heat insulating material attachment 1 can be divided into two heat insulating material attachments 1 '. As shown in FIG. 2, the divided heat insulating material fitting 1 ′ can be used for a base 8 a on the outer periphery of the house where the heat insulating material 8 is disposed only on one side.

  A drooping piece 3 is formed at both ends of the locking piece 2 by being bent downward. The length of the hanging piece 3 is a length corresponding to the thickness of the heat insulating material 8 (see FIG. 2), and the length at which the tip of the support piece 5 comes into contact with the lower side surface of the floor structure member 8. The hanging piece 3 is formed with a reinforcing rib 12a protruding in the vertical direction on the opposite side to the locking piece 2.

  The lower end portions of the both drooping pieces 3 are bent to the opposite side to the locking pieces 2 to form receiving pieces 4 projecting substantially horizontally. The receiving piece 4 receives the heat insulating material 8 inserted between the floor structure members 8 from the bottom as shown in FIG. In addition, a reinforcing rib is formed at the bent portion between the hanging piece 3 and the receiving piece 4 so as to protrude toward the valley fold side and straddle between the hanging piece 3 and the receiving piece 4. The reinforcing rib 12b can be formed by applying a jig to the valley fold side of the bent portion between the hanging piece 3 and the receiving piece 4 and performing a die pressing process or a die punching process from the mountain fold side. By providing this reinforcing rib 12b, even if the receiving piece 4 is pushed from above, it can be made difficult to be pushed down.

  The front end portion of the receiving piece 4 is folded downward toward the locking piece 2 to form a support piece 5. The tip of the support piece 5 protrudes toward the locking piece 2 from the hanging piece 3. Each support piece 5 has a tooth portion 6 at its tip. The support piece 5 has a toothed portion 6 protruding from the hanging piece 3 toward the locking piece 2 on the side surface of the floor structure member 8 (see FIG. 2), so that the support piece 5 has a brace shape below the receiving piece 4. The receiving piece 4 is supported. The bending angle between the receiving piece 4 and the supporting piece 5 depends on the protruding length of the receiving piece 4, but if it is too large, the tip of the supporting piece 5 tends to protrude downward from the side surface of the floor structure member 8 and is too small. And a sufficient support force by the support piece 5 is difficult to obtain, and about 5 to 20 degrees is preferable.

  As shown in FIG. 2, the heat insulating material fixtures 1, 1 ′ are used to hold the heat insulating material 8 that is hung on the floor structural member 8 and inserted between the floor structural members 8. In FIG. 2, the insulator 8 having the hanging piece 3, the receiving piece 4, and the support piece 5 formed on both sides of the locking piece 2 is hung on the large pull 8b, and the locking piece 2 is mounted on the base 8a. On one side, a heat insulating material fitting 1 ′ having a hanging piece 3, a receiving piece 4 and a supporting piece 5 is hung. The heat insulating material 8 inserted between the floor structural members 8 is held on the receiving piece 4 of each heat insulating material fitting 1, 1 ′.

  The heat insulating material 8 is preferably lightweight and excellent in water resistance, heat insulating property, and pressure resistance, and a synthetic resin foam having closed cells is preferable. Specifically, for example, a synthetic resin foam having closed cells such as a polystyrene foam, a polyethylene foam, a polypropylene foam, a polyurethane foam, and a phenol foam is preferable. In particular, extruded polystyrene foam is most preferred because of its high heat insulation and low water absorption.

  The heat insulating material fitting 1 ′ can be manufactured and used as a single product by punching a strip-shaped flat plate having a tooth portion 6 formed on one side from a metal plate and bending the flat plate. However, as shown in FIG. 1, if the heat insulating material fitting 1 ′ is obtained by dividing it, one type of component can be used for two applications, and two types of components can be used. This is preferable because it can save time and effort.

  The heat insulating material fittings 1 and 1 'can be used to attach a heat insulating material (not shown) to be inserted between the joists by hanging the joist (not shown) in a wooden frame construction house. . However, the floor structure with a high side surface height is set so that the length of the drooping piece 3 does not limit the thickness of the heat insulating material 8 so that the tooth portion 6 can be inserted into the side surface of the floor structure member 8. It is preferable to apply to the member 8. That is, it is preferable to use the base 8a or the large pulling 8b of the house of the wooden frame construction method or the floor joist (not shown) of the house of the 2 × 4 construction method.
