Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a packing for a building foundation interposed between a concrete cloth foundation and a wooden base in a building such as a house.

[0002]

[Prior art]

 In order to form an effective underfloor ventilation path, the construction method using foundation packing has been increasing recently. A general form of this basic packing is a flat rectangular block having a material of plastic and an outer shape of about 90 to 120 mm in width, about 100 to 200 mm in length, and about 10 to 40 mm in thickness. A plurality of holes for passing anchor bolts are formed in the center of the plane.

[0003]

[Problems to be solved by the invention]

 The foundation packing method is used to improve the ventilation under the floor, but it is required that some parts of the building have no ventilation. For example, at the entrance, if there is a gap between the cloth foundation and the base, warm air in the room will flow out from here, or cold outside air will enter, and the heat insulation of the room will be impaired. . In addition, since fixing and holding after the installation of the foundation packing is usually performed by anchor bolts, holes for inserting anchor bolts are formed in the foundation packing. However, the installation position of the anchor bolts with respect to the cloth foundation is not always strict, and the arrangement position of the foundation packing is not necessarily determined depending on whether the core is aligned with the cloth foundation or the outer edge is aligned. Not constant. For this reason, the holes formed in the foundation packing and the anchor bolts often become misaligned at the actual site, which hinders construction.

[0004] In view of the above, the present invention has an object to provide a base packing used for completely hermetically shielding a space between a cloth foundation and a base. Another object of the present invention is to provide a foundation packing that can be installed at a desired position without being affected by the position of an anchor bolt.

[0005]

[Means for Solving the Problems]

 The technical means of the basic packing of the present invention consists of a packing body and an elastic material, and an elastic material is interposed on both the front and back surfaces of the packing body and a butt connection between the packing bodies to maintain airtightness. It is in.

Further, a narrow groove may be formed in the longitudinal direction on both the front and back surfaces of the packing body, and an elastic material may be fitted into the narrow groove.

Further, the technical means of the basic packing of the present invention is that a plurality of anchor bolt insertion holes are formed in the packing body, and the shape of this hole is to turn the packing body upside down or to turn left and right. As a result, the range of the hole extends to the entire central portion of the packing body.

[0008] Furthermore, score lines for marking may be formed on both front and back surfaces of the packing body.

[0009]

[Embodiment of the invention]

 An embodiment of the basic packing of the present invention will be described based on an example of the drawings. The basic packing comprises a packing body 1 and elastic members 2 and 3 as shown in FIG. The outer shape of the packing body 1 is a flat rectangular block, made of hard plastic, and integrally formed. The external dimensions of the illustrated example are 120 mm in width, 500 mm in length, and 20 mm in thickness, but the dimensions can be freely changed according to the embodiment.

The packing body 1 has the same shape on both the front and back surfaces, and two narrow grooves 4 are formed on the surface along the entire length in the longitudinal direction. Then, the elastic material 2 is fitted into the narrow groove 4. Therefore, the state at the time of installation is as shown in FIG. 2, and the gap between the fabric base 10 or the base 11 and the packing body 1 is completely shielded by the elastic material 2. As shown in FIG. 1, a score line 5 is formed near the edges on both the front and back surfaces of the packing body 1, and this mark serves as a mark when a board such as an exterior plate is installed, and is also provided with an anchor bolt on the base. It plays a useful role in practice, such as a guide for positioning when drilling holes.

The packing body 1 is used only in a place where it is necessary to shield between the cloth foundation 10 and the base 11 in a building. FIG. 3 is an example used for the entrance. At the time of disposition, an elastic material 3 is interposed at the butt connecting portion between the packing bodies 1 so that no gap is formed at the connecting portion. In the figure, reference numeral 12 denotes a normal foundation packing. The elastic members 2 and 3 can be made of any material such as rubber or soft synthetic resin, and any material can be used as long as it can fill the gaps and secure airtightness. Further, in the embodiment, the elastic members 2 and 3 are separate bodies, but they may be integrated. Further, the elastic member 2 may be formed in a ring shape. In this case, narrow grooves into which the elastic member 2 is fitted may be formed on both end surfaces of the packing body. In this case, the elastic member 3 is unnecessary.

As shown in FIG. 1, a plurality of (four in the illustrated example) holes 6 for inserting anchor bolts are formed in the packing body 1. Therefore, as shown in FIG. 4, the packing body 1 is disposed between the cloth base 10 and the base 11, and is then fixed by the anchor bolts 13 and the nuts 14. The anchor bolts 13 are buried in the lower part and protruded in the upper part when the concrete fabric base 10 is cast. However, the placement position is not always determined in consideration of the placement position of the packing body. For this reason, when forming the hole 6 in the packing body 1, it is necessary to prevent the position of the anchor bolt 13 from affecting the arrangement position. In the illustrated embodiment, diagonal hexagonal holes are provided at appropriate intervals, and a trapezoidal hole is provided at one end. Therefore, as shown in FIG. 5, the area of the hole 6 is the area 6A when the hole is in the normal arrangement, but the area 6B is increased by turning the packing body 1 upside down. In addition, the range C is added by the reversal of the front and back. Therefore, as a whole, the range of the hole 6 covers the entire central portion of the packing body 1, so that the packing body 1 can be arranged at a desired position regardless of the position of the anchor bolt. become. The shape and position of the hole 6 are not limited to the shapes shown in the drawings, but the point is that the packing body 1 can be arranged at a desired position regardless of the position of the anchor bolt. The shape of the hole and the like can be freely determined without being limited to the illustrated embodiment.

The present invention is not limited to the above embodiment, and can be freely modified and implemented within the scope of the claims of the present invention. In particular, the shapes of the narrow grooves 4 and the holes 6 and the materials and shapes of the elastic members 2 and 3 are arbitrary.

[0014]

[Effect of the invention]

 In the basic packing of the present invention, an elastic material is interposed on both the front and back surfaces of the packing body and the butt connection part, and the space between the cloth foundation and the base is completely airtightly shielded, so that it is necessary to prevent air from flowing in and out. For example, if it is used at the entrance, it can prevent the outflow of warm room air and the inflow of cold outside air, and it has an excellent effect on heat retention. Also, since the structure is simple and the manufacturing cost is low, it can be implemented at low cost.

According to the second aspect, since the elastic material is fitted into the narrow grooves on the front and back of the packing body, the position of the elastic material can be reliably maintained, and the airtightness can be improved. Wear.

According to the third aspect, since the foundation packing can be arranged at a desired position without being affected by the position of the anchor bolt, it is excellent in workability and extremely useful in practical use.

[0017] Since the invention according to claim 4 has a ruled line, it is very convenient in an actual construction site, for example, as a mark for positioning when attaching an exterior plate, and is intended to improve workability. Can be.
