Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation packing used in a building such as a house, which is interposed between a cloth foundation and a base to form an air passage for underfloor ventilation.

[0002]

2. Description of the Related Art Conventional foundation packings usually have a length of 2
A block body of about 0 cm, which is interposed between the cloth foundation and the foundation to form a gap between the cloth foundation and the foundation, and the gap serves as a ventilation path for underfloor ventilation. Is. Further, a long base packing in which a ventilation hole is formed in the packing itself and is laid along the entire length of the cloth base is also proposed as JP-A-2002-70186.

[0003]

However, in the case of the above-mentioned conventional basic packing, for example, in the case of a short one, it is important to specify the installation location, and it is necessary to carefully determine the installation location at the time of construction. May be caused. This problem can be solved by using a long basic packing,
The packing itself must be provided with ventilation holes, and the thickness of the packing is as thin as about 10 to 30 mm. Therefore, if ventilation holes are provided in the packing in the width direction, the ventilation holes will become smaller and a sufficient amount of ventilation will be provided. There is a problem that it cannot be secured.

In view of the above points, the present invention is to provide a long basic packing capable of ensuring sufficient air permeability. The present invention also provides a foundation packing capable of drying the contact surface of a cloth foundation or a base.

[0005]

The technical means of the basic packing of the present invention is to provide a basic packing in a long basic packing which is interposed along the entire length between the cloth foundation and the base. Is formed with a large number of vent holes extending in the width direction, and the upper surface or the lower surface of the vent holes has an open shape.

Further, it is preferable that the ventilation holes are formed with open portions alternately on the upper and lower surfaces along the longitudinal direction and the width direction of the packing. Furthermore, it is preferable to form notches in both edges of the back surface of the foundation packing so as to absorb concrete casting burr of the cloth foundation. Further, it is preferable that a hole for the anchor bolt to pass through is continuously provided along the entire length in the center portion of the base packing in a plane, and the formation position of this hole is asymmetric in the longitudinal direction of the packing.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a basic packing of the present invention will be described based on an embodiment of the drawings. The base packing 1 usually has a thickness of 10 to 30 mm. In addition, the width is 70 to 200 mm and is determined according to the width of the base.
The length is as long as about 500 to 2000 mm, and these are connected in series and, in some cases, appropriately cut before use. The material is rigid or has some elasticity,
For example, synthetic resin, rubber, metal, ceramic or the like can be used. In the examples, polypropylene resin is used.

A large number of vent holes 2 are formed in the basic packing 1 so as to extend in the width direction. Since the basic packing 1 receives a compressive load in the thickness direction during use, when forming the ventilation holes 2, it is designed so as to ensure the required compressive strength. In the illustrated example, the cross-sectional shape of the holes is a quadrangular shape, and a plurality of adjacent holes are continuously formed. Further, each hole 2 has an opening 3 formed on either the upper or lower wall surface. That is,
Each hole is in the form of a three-sided enclosure consisting of the left and right side walls 4 and one of the upper and lower walls 5, and the other one is an open part 3, where ventilation is possible freely. As a result, the ventilation area can be increased, the ventilation performance can be enhanced, and the contact surfaces of the cloth foundation and the base that are in contact with each other can be dried. In addition, the open portions 3 are alternately formed in the vertical direction along the longitudinal direction and the width direction of the packing. As a result, it is possible to suppress a decrease in the flexural strength of the packing due to the formation of the open portion.

In the basic packing 1, a square hole 6 for passing an anchor bolt is formed continuously in the central portion of the basic packing along the entire length thereof. Further, as shown in FIG. 3, a convex portion 7 and a concave portion 8 for connection are formed at both ends of the basic packing 1 so that the packing can be connected in series and used. Further, as shown in FIG. 3, the formation positions of the holes 6 for the anchor bolts are asymmetrical in the longitudinal direction of the packing. Therefore, if the anchor bolts do not fit in the holes 6 well, Use it with the direction reversed. Further, 9 in FIG. 3 is a hole for nailing. Note that the front and back surfaces of the packing 1 may be textured to prevent slipping.

The above basic packing 1 is composed of a cloth foundation 2
It is used by laying it on top of 0 in series. Further, the packing 1 is used after being cut appropriately according to the length of the cloth foundation 20. As shown in FIG. 5, slanted notches 10 are formed on both edges of the back surface of the base packing 1, and burrs 21 at the upper corners of the top corners are produced by concrete pouring when forming the cloth base 20. Can be absorbed. Therefore, the burr 21
Even if there is, there is no problem in arranging the packing 1. 30 is the base.

As described above, since the packing 1 interposed between the cloth foundation 20 and the base 30 is formed with a large number of vent holes 2, air can flow through the holes.
Can provide underfloor ventilation. Furthermore, since either the upper surface or the lower surface of the ventilation hole 2 has an open shape, the ventilation surface is rich and the contact surface of the cloth foundation 20 and the base 30 can be dried. Furthermore, since there is a notch due to the formation of the opening on the front and back surfaces of the packing 1, this will prevent slipping when it comes into contact with the cloth foundation or base, and the packing interposed between the cloth foundation and the base will Stable and well held together.

The present invention is not limited to the above embodiments, but can be freely modified and implemented within the scope of the claims. In particular, the thickness, width, length of the packing 1,
And the material is free. Further, the cross-sectional shape of the ventilation holes 2 is not limited to a quadrangular shape, and the number of ventilation holes formed can be freely set. Further, the shape and formation of the open portion 3 of the vent hole 2 are also free.

[0013]

Since the foundation packing of the present invention is laid out along the entire length of the cloth foundation, it is not necessary to pay attention to the packing installation position, construction errors can be prevented, and since the packing has ventilation holes, it can be installed under the floor. Ventilation can be achieved. Furthermore,
Since the ventilation holes provided in the packing are open at the upper and lower sides, the ventilation performance is high and sufficient underfloor ventilation can be achieved even when the packing is thin. Also, since there are open parts on the front and back of the packing, it is possible to dry the contact surface of the cloth foundation and the base well, and the open part prevents slipping in the contact state, so stability when using the packing is stable. Good.

According to the second aspect of the present invention, since the open portions are formed alternately on the upper and lower surfaces, it is possible to suppress the decrease in the flexural strength of the packing and to homogenize the drying of the contact surface.

According to the third aspect of the present invention, since the notch for absorbing the burr of the cloth base is formed in the edge of the packing, the packing can be stably placed on the cloth base without being affected by the presence of the burr. .

According to the fourth aspect of the present invention, the holes for the anchor bolts are provided asymmetrically in the longitudinal direction. Therefore, when the positions of the holes and the bolts are not properly aligned, the packing is reversed in the longitudinal direction. If they do, they will fit, which is extremely useful in construction.
