Description

The present invention relates to a foundation packing interposed between a concrete foundation of a wooden house and a wooden base.

The basic packing is a building member devised for the first time by the present applicant. It has a long track record and is still used for the construction of many Japanese houses. The shape and material of the basic packing are described in detail in Patent Documents 1 to 3, which are the prior applications of the present applicant.

When constructing a wooden house, a concrete foundation is made on the outer shell or inner shell of the part where the building is to be built, a wooden base is fixed on it, a pillar is placed on the wooden base, It was supposed to put a beam on. The traditional Japanese architectural method of placing a wooden base on a concrete foundation is widely adopted. However, this has the following difficulties.

A concrete foundation (cloth foundation) is made by mixing cement, sand, and water into a fluidized form, pouring into a pre-assembled formwork, and allowing it to stand for several days to solidify. Therefore, the foundation contains a large amount of moisture. When the wooden foundation is in contact with the concrete foundation, it absorbs moisture from the foundation and becomes difficult to wet and dry.

Also, there is no gap between the concrete foundation and the wooden base, so there is no ventilation. The underfloor must be ventilated. Therefore, it is necessary to provide ventilation holes somewhere on the concrete foundation. The ventilation hole has a size of about 200 mm (vertical) × 400 mm (horizontal), for example. Since it is a fairly wide opening and lowers the strength of the foundation, a large number cannot be provided on the foundation wall surface. Therefore, moisture tends to stay in the corners far from the ventilation holes in the underfloor space.

Under the floor of a Japanese house is like that, it is poorly ventilated and easily humid. The wooden foundation absorbs moisture under the floor and moisture of the concrete foundation and is always moist. As a result, the foundation may decay over the years. Due to moisture and temperature, termites can thrive and eat the foundation. In case of poor ventilation, in addition to termites, decaying fungi propagated on the foundations and pillars, causing the foundations and pillars to decay. In addition, the concrete foundation is cracked from the corner of the ventilation hole and the foundation is compromised.

The basic packing was created by the present applicant in order to improve the ventilation of such an underfloor space and facilitate the construction work. The basic packing of the present applicant is a plate made of a non-perishable material having a black length of 204 mm (214 mm when including a protrusion), a width of 100 mm, and a thickness of 20 mm. For example, a metal (stainless steel) plate or a composite plate of inorganic material and plastic. As the composite material, for example, plastics such as polypropylene, polyethylene, nylon, and ABS can be used. As the inorganic material, calcium carbonate powder, talc, wood powder and the like can be used. In addition, a coloring agent may be added for coloring. In the case of coloring in black, a recycled product can be used as the plastic material. In the case of other bright colors, it is necessary to use a new plastic material. Moreover, it is not necessary to add an inorganic material.

Mixing inorganic materials can save plastic materials. Not only can plastics be saved, but physical and chemical performance can be enhanced. Since a large amount of inorganic material powder is contained, the rigidity becomes high and the hardness is suitable for building materials. Moreover, since the light is blocked, the plastic does not become brittle due to the light. Blocks air without passing water. Inorganic materials shield the action of drugs and drugs. The inorganic material can give an appropriate weight.

Therefore, when an inorganic material is added, it becomes superior to plastic itself in terms of water resistance, weather resistance, light resistance, heat resistance, rigidity, life, weight, etc. required for building materials.

FIG. 22 shows the basic packing manufactured and sold by the applicant. The front and rear sides have 3 to 4 depressions, and the longitudinal ends have protrusions and depressions. The side with the protrusion is called the instep end side, and the side with the depression is called the end side. The protrusion and the recess have a shape that allows male and female fitting. A groove is formed in the longitudinal direction for ventilation between the base and the packing.

When the protrusions on the edge side of the foundation packing A are fitted into the recesses on the edge of the foundation packing B, the two foundation packings A and B can be joined in the longitudinal direction. When the instep protrusions of the base packing A are fitted into the front and rear side recesses of the base packing B, the two base packings A and B can be combined into a T shape. In this way, the foundation packings can be connected in the longitudinal direction or the front-rear direction and arranged on the surface of the concrete foundation.

The base packing has through holes that penetrate the front and back. This is a hole for the anchor bolt to pass through. Anchor bolts are planted upward from the concrete foundation. The wooden base is thereby fixed, but the bolt holes of the foundation packing are for fixing the base through anchor bolts.

Place the foundation packing on the concrete foundation where the anchor bolts are located. At the corners at right angles, two basic packings are combined into a T-shape and an L-shape. In the straight portion, the base packing may be used alone, but the two base packings may be connected in series. Place one or two foundation packings on the concrete foundation with anchor bolts. Rather than placing the foundation packing on all sides of the concrete foundation, place them at regular intervals. Place the base wood with anchor bolt holes on it. A concrete foundation, foundation packing, and wooden base are joined by screwing and tightening a nut to an anchor bolt. Instead, there is a place just to put the basic packing.

Since the portion without the base packing is a gap (opening) having a height of about 20 mm, this is a gap that functions as a ventilation window. This is the most important role of the basic packing. Ventilation function is sufficient because the height is narrow but long to the side. There is no need to make ventilation windows on the concrete foundation. The foundation work can be saved because no ventilation windows are made on the concrete foundation. There is an excellent advantage that the foundation is strong because there is no ventilation window of the foundation. Since the foundation is solid and there is no skidding, it is a structure that can withstand earthquakes well.

Moisture does not invade the wooden base because the foundation packing blocks the concrete foundation and wooden base that contain water. For this reason, the foundation is not easily decayed and is not easily damaged by termites. For this reason, the durability of the foundation is increased and the life is extended.

Such a method using the foundation packing is called a foundation packing method. The basic packing method has the advantages of good ventilation and energy saving, the base is protected from termites and decaying fungi, the building is robust, strong against earthquakes, easy to install, and labor-saving. . As a result, it is possible to construct a highly durable house.

Patent Document 4 discloses a small animal intrusion prevention member that is inserted into a gap between a base packing and a base packing so as to prevent the entry, exit, and entry of rats, frogs, and snakes.
Patent Documents 1 to 4 all belong to the present applicant. Other similar members have been devised by other companies.

The “laying method of a floor panel with a pedestal and a pedestal interposed” disclosed in Patent Document 5 is a method in which a rectangular shaped pedestal such as a ladder is interposed between a concrete foundation and a foundation. Like the ladder, the opening is much wider than the solid part. It has the advantage that the position of the pedestal can be freely changed with respect to the anchor bolt. Because of that, the ability to carry the load per length is reduced, so the pedestal can be spread on the surface of the concrete foundation without any gaps.

Patent Document 6 discloses a “carriage” in which a rectangular pallet with many ladder-like openings is placed on a concrete foundation, a wooden base is placed on the cradle, anchor bolts are passed through nuts. A timber base is fixed. Since it is a pedestal, the opening in the vertical direction is large, but it alone does not provide air permeability. Therefore, here, an opening in the horizontal direction is also provided to provide air permeability. Because there are many through holes both in the vertical and horizontal directions, it becomes fragile. According to the present invention, a short partition wall connecting the upper and lower wall surfaces is inclined rather than orthogonal to the upper and lower walls. In other words, the hole seen from the side repeats an upright trapezoid and an inverted trapezoid. Since the partition wall is inclined on both sides, the horizontal displacement of the top and bottom surfaces is prevented. Furthermore, in order to secure the strength in the vertical direction, this pedestal is also spread over the concrete foundation without any gaps. It is a basic packing with air permeability.

The “floor-floor underfloor airtight heat insulating structure” disclosed in Patent Document 7 provides a highly airtight trolley interposed between a water-floored floor material such as a bathroom and a toilet and a concrete foundation. Tape-like rubber is attached to both sides of a ladder-like plastic material. If you put the base wheel between the concrete foundation and the wood foundation and fix it, there will be rubber, so there will be almost no wind or steam inside and outside. Emphasis on airtightness. The present invention relates to a shield-type basic packing and has something in common.

Japanese Utility Model Publication No. 54-181721 Japanese Utility Model Publication No. 54-181708 Japanese Patent Publication No. 55-40734 No. 4-5610 JP-A-8-74367 JP 2000-265578 A Japanese Patent Laid-Open No. 7-197675

In this way, the foundation packing method has advantages over conventional methods such as extending the life of buildings, being strong against earthquakes, saving labor in construction, and protecting the foundation from termites and decay. Although the basic packing of the basic type in FIG. 22 is solid, a gap is created and air permeability is obtained by arranging it loosely on a concrete foundation. In addition to the basic type shown in FIG. 22, several improvements have been proposed. Although the original purpose was mainly based on the underfloor breathability, there is a case where it is desired to use the basic packing even in a portion where the breathability is unnecessary as described in Patent Document 7.

When there is no under floor such as the entrance, the entrance, or the soil, and the indoor space and the external space are in contact on both sides via the base, it is not necessary to ventilate the foundation packing. Even in that case, the foundation packing is interposed between the concrete foundation and the foundation, the wooden foundation is fixed, and the wall is painted. In that case, air permeability is unnecessary. Here, the basic packing that does not require air permeability is referred to as a shielding type. It is a ventilation type and a counter electrode concept. In the case of the shielding type, the mortar covers the front and back of the basic packing itself. However, plastering materials such as mortar have the disadvantage that they do not adhere well to the basic packing. The first object of the present invention is to improve the attachment of mortar and the like in the basic packing. Improve adhesion to mortar and wall material to prevent peeling of wall and mortar materials. A second object is to provide a basic packing having a structure capable of reducing the material.

In order to solve the above-described problems, the present invention is a member interposed in a horizontal direction between a concrete foundation and a wooden base, and is a flat rectangular plate extending in a longitudinal direction, for passing a bolt. There is provided a basic packing characterized in that the above-mentioned hole is formed in the vertical direction, and has a plurality of longitudinal grooves for adhering the mortar on the front and rear surfaces, and a plurality of cavities are provided in the member.

The basic packing of the present invention has a number of longitudinal grooves on the front and rear surfaces. This is to increase the adhesion with the mortar. When unevenness is provided on the front and back surfaces, it is only necessary to provide a large number of unevenness, and the shape and dimensional height of the unevenness can be freely determined according to the purpose. The unevenness includes vertical grooves. Round and square projections can also be provided. The arrangement of the protrusions may be a vertical and horizontal matrix, or may be a staggered arrangement. Further, parallel grooves may be formed on the front and rear surfaces. A parallel groove may be parallel to the longitudinal direction or may be orthogonal to the longitudinal direction. Furthermore, parallel grooves that are inclined in the longitudinal direction may be provided. Two sets of parallel grooves can also be formed. By forming a plurality of longitudinal grooves on the front and back surfaces in contact with the mortar and wall material, the adhesion is improved, so that the wall or mortar does not peel off over the years. Furthermore, the basic packing of the present invention is divided into two parts in the front and rear directions so as to form a large number of cavities inside and save material. The base packing divided into two in the front and rear is attached to the front and back. Since many cavities are formed inside, material can be saved.

The basic packing of the present invention is excellent in adhesiveness to mortar because it is provided with many longitudinal grooves on the front surface and the rear surface when coating with mortar. In addition, since the base packing is divided into two parts at the front and back, and a large number of cavities are provided in the member, the material cost can be reduced, the cost can be reduced, and the weight can be reduced.

The basic packing of the present invention is provided with irregularities on the front and rear surfaces in order to improve adhesion with a mortar material or the like. The type of unevenness is arbitrary such as a set of isolated points and a set of grooves. Furthermore, if the ridge line which is the intersection line of the front and rear surfaces is chamfered, it is not necessary to deburr the concrete foundation. Even if there are burrs, it is possible to place the base packing horizontally on the foundation. In addition, a large number of cavities are provided in the member in two parts, front and rear or upper and lower. The weight can be reduced and the material cost can be reduced.

The material of the basic packing is a metal material, a plastic material, or a composite material of plastic and an inorganic material. In the case of metal, cast iron, stainless steel, etc. can be used. In the case of plastic, thermoplastic and thermosetting plastics such as polyethylene, polypropylene, ABS, and nylon can be used. In the case of a composite material of a plastic and an inorganic material, it is made of a thermoplastic or thermosetting plastic such as polyethylene, polypropylene, ABS, or nylon, an inorganic material such as CaCO 3, wood powder, or stone powder, or a pigment. The blending weight ratio of the plastic and the inorganic substance is about 1: 0.1 to 1: 3. In the case of a composite material, a recycled material can be used as the plastic.

A basic packing according to some embodiments will be described with reference to FIGS. 1 to 20 and FIGS. 23 to 26.
[Example 1 (with longitudinal grooves; FIGS. 1 to 7)]
FIG. 1 is a plan view of the entire base packing 1 according to the first embodiment, and FIG. 2 is a front view. The basic packing of Example 1 has a length in the longitudinal direction of 500 mm, a width in the front-rear direction of 120 mm, and a thickness of 20 mm. Although it has been stated that the basic foundation packing is 214 mm × 100 mm × 20 mm, this may also be such a dimension. However, the dimensions of the basic packing of the unit can be determined freely according to the purpose and demand. The direction will be described using this definition as needed, with the longitudinal direction being the x-axis, the vertical direction being the z-axis, and the front-rear direction being the y-axis direction.

Since it is a basic packing, it is a vertically long (extending in the x direction) rectangular member and has a wide upper surface 2 and a lower surface 3 that are parallel in the vertical direction. The upper surface 2 and the lower surface 3 have the same shape pattern. There is a joint 4 at the middle part, connecting the front and rear sides. Between the joints 4, there is an anchor bolt hole 5 having a modified hexagonal shape. This is a hole for the anchor bolts planted in the concrete foundation. The anchor bolt hole 5 is slightly wider so that some adjustment is possible. However, the shape of the anchor bolt hole 5 is arbitrary. It may be a T-shaped groove like the basic packing described as the basic shape, or may be a round anchor bolt hole.

The left and right end surfaces 6 are flat surfaces. A large number of foundation packings are continuously arranged on the concrete foundation, but if they have such a flat end face, they can simply be put together and placed on the foundation. A male and female fitting portion may be provided on the end face as in the basic form.

The front surface 7 and the rear surface 8 of the foundation packing 1 are also parallel surfaces. This shape is one feature of the present invention. That is the presence of multiple longitudinal grooves 9. Similarly, the front surface 7 and the rear surface 8 have irregularities formed by the vertical grooves 9. This is to increase the adhesion with the mortar. Mortar is applied to the front surface and the rear surface, but if the surface is smooth, the mortar paste is poor, so the present invention has a shape rich in irregularities.

A plurality of small grooves 10 parallel to the longitudinal direction are formed on the upper surface 2 and the lower surface 3. In addition, recesses 11 and 12 are formed in a part of the joint 4. The shape and size of the irregularities on these upper and lower surfaces are arbitrary. Of course, it does not matter if there are no such irregularities.

In parallel, two tape grooves 13 are formed over the entire length. This is one in which a rubber tape, urethane tape, foamed resin tape or the like is attached here. Although the illustration of the tape is omitted here, a flexible material tape is actually attached here. When the foundation packing 1 is placed between the concrete foundation and the foundation, the tape is compressed and airtightness can be improved. This is the tape groove 13 for that purpose. The depths of the recesses 11 and 12 and the tape groove 13 can be seen from FIGS. As is clear from the cross-sectional view of FIG. 4, the lower and upper surfaces are flat and the cross section is substantially rectangular, but there are concave portions in some places.

FIG. 5 is a perspective view showing a state in which the foundation packing 1 of the present invention is placed on the concrete foundation 20. FIG. 6 is a perspective view in which a wood base 24 is further placed on the foundation packing 1. Anchor bolts sit on the concrete foundation, which passes through the anchor bolt holes 5 of the foundation packing 1 and through the base bolt holes. A nut is screwed into the bolt, and the foundation packing 1 and the base 24 are fixed to the concrete foundation 20.

Here, the width of the concrete foundation 20 and the foundation packing 1 is drawn in the same manner, but the width of the concrete foundation 20 may be larger. The mortar 21 is applied until reaching the front surface of the concrete foundation 20, the front surface of the foundation packing 1, and the base 24. At this time, the mortar 21 enters the concave portion of the longitudinal groove 9 on the front surface of the basic packing 1 and is cured. For this reason, the mortar 21 and the base packing 1 adhere firmly. Since the mortar surface becomes a chain of unevenness according to the unevenness of the basic packing, no lateral displacement can occur. In addition, the mortar is less likely to peel from the front surface of the basic packing. A cosmetic mortar or tile 23 is further attached to the surface of the mortar 21.

FIG. 7 shows an enlarged cross-sectional view of a portion where the mortar 21 and the base packing 1 are in contact with each other. Since the mortar 21 is contained in the concave and convex portions of the vertical grooves 9, it can be seen that the bonding is strengthened. The pitch of the vertical grooves, the spread of the concave portions, the width of the convex portions, the length of the convex portions, and the like can be arbitrarily determined. In this example, the pitch (cycle) of the longitudinal grooves is 11 mm.

[Example 2 (with longitudinal grooves; chamfered; FIGS. 8 to 14)]
In Example 2 described below, the ridgelines on the upper and lower surfaces of the basic packing are chamfered. Chamfering the ridgeline has the advantage that it can be placed so that the bottom surface is in contact with the foundation surface even if there is a raised part (burr) on the concrete foundation. The width, height and angle of chamfering are arbitrary. FIG. 8 is a plan view of the basic packing of Example 2, and FIG. 9 is a front view. The basic packing of Example 2 has a length in the longitudinal direction of 500 mm, a width in the front-rear direction of 120 mm, and a thickness of 20 mm. Such dimensions may be determined arbitrarily. This is the same as in the first embodiment. Since the mortar also enters the chamfered portion, there is an advantage that peeling or cracking after drying of the mortar is less likely to occur. Other configurations are the same as those of the first embodiment. Therefore, the same code | symbol was attached | subjected to the common part.

It is a vertically long rectangular member (extending in the x direction), and has a wide upper surface 2 and a lower surface 3 that are parallel in the vertical direction. Both the upper surface 2 and the lower surface 3 are divided into the front and the rear, and there is a joint 4 at the middle part to connect the front and rear sides. Between the joints 4, there is an anchor bolt hole 5 having a modified hexagonal shape. The left and right end surfaces 6 are flat surfaces. A male and female fitting portion may be provided on the end face as in the basic form.

The front surface 7 and the rear surface 8 of the base packing 1 are also parallel surfaces, and the longitudinal grooves 9 are formed on the entire surface. This is to increase the tightness with the mortar. Since this is the same as in the first embodiment, this property will not be described again. The chamfered structure can be applied to a basic shape without a vertical groove.

A shape device newly provided in the second embodiment is that the ridgelines of the upper and lower front and rear surfaces are chamfered. The chamfer 15 is an oblique narrow and narrow surface. The chamfer 15 hangs over the entire vertical groove 9. The only difference from Example 1 is that a basic packing having chamfering can be made by devising the mold a little.

Describe the effect of chamfering. As shown in FIG. 12, a concrete foundation 20 is manufactured by inserting a hole formwork 25 into a ground to be used as a wall surface in a construction site, and combining and pouring concrete. When solidifying, a portion where the concrete slightly protrudes may remain at the portion that contacts the mold 25. This is called a burr 26. Although it is a slight bulge, it is not scraped off and remains at both ends of the upper surface 27 of the concrete foundation as shown in FIG. There is no problem if the width of the foundation packing is smaller than the concrete foundation width.

If a foundation packing having the same width is placed thereon, the foundation packing is a flat surface, so that the intermediate portion is lifted due to the burr 26. Alternatively, it is possible that only one side is slightly higher and the base packing is slanted. Since Example 2 chamfers 15 the ridgelines of the front and rear surfaces of the foundation packing 1, even the foundation packing having the same width cannot be lifted by the burr 26. FIG. 14 shows a state in which the foundation packing of Example 2 is placed on the concrete foundation 20.

Although the burr 26 exists in the front and rear, the foundation packing 1 has a chamfer 15 and the portion is lifted so as not to be affected by the burr 26. It has a convenient shape. The burr 26 is only a small ridge, but it is troublesome to cut it after it is solidified, so such a device is useful. The chamfering width, angle and height are arbitrary. In this embodiment, the chamfering depth is 4 mm and the reduction width is 1 mm. Therefore, the inclination angle is 14 °. However, such dimensional angles can be freely designed in relation to the concrete foundation.

[Example 3 (with longitudinal groove; with chamfering; vertically divided into two; FIGS. 15 to 20)]
There are also requests to further reduce weight and cost. To make it lighter, the inside should be made space. In the case of a metal base packing, it is difficult to make a hollow inside because it is an integral one. Plastic base packing is manufactured at once by plastic injection molding, but it is difficult to make a cavity inside. The present invention can introduce a cavity into the interior by dividing the base packing into two members. There may be two modes of division, upper and lower division and front and rear division. State both.

In Example 3 to be described next, the base packing is cut at the surface of the center height, and is divided into upper and lower parts to provide a hollow part. There are longitudinal grooves 9 on the front and rear surfaces and chamfers 15 on the front and rear vertical ridge lines. Therefore, there are the same effects as in the first and second embodiments. In addition to that, Example 3 provides a base packing having two halves and having a cavity. Since it is divided in two, this is a somewhat complicated structure.

Dividing into two in this way allows the interior to be hollow. So you can save material. However, the upper and lower surfaces that contact the concrete foundation and foundation have a sufficient area, and the contact area does not have to be reduced. There is also an advantage that it can be used upside down.

15 is a plan view of the basic packing of Example 3, and FIG. 16 is a front view. Looking only at the plan view, it is almost the same as the basic packing of the second embodiment. It is a long plate in the x direction having an upper surface 2, a lower surface 3, an end surface 6, a front surface 7, and a rear surface 8. As a configuration common to the first and second embodiments, the front and rear surfaces 7 and 8 have longitudinal grooves 9. This improves the adhesion with the mortar coating and prevents the mortar from peeling off. There is a chamfer 15 along the ridgeline. This is a structure provided to avoid burrs on concrete foundations. However, looking at the front view, it can be seen that the line is divided into two because the fitting line can be seen at exactly half the height.

This basic packing is divided into upper and lower parts and consists of an upper piece K and a second piece H. Upper K and B H are similar rectangular plates. In FIG. 15, the upper surface (surface) of the upper piece K is visible, but the bottom surface (front surface) of the second piece H has the same shape. Each back surface has a structure for fitting, a reinforcing member, and a fitting member.

FIG. 17 shows the back surface 2 of the upper piece K, and FIG. A large number of parallel lateral grooves 16 and lateral stripes 17 are alternately present in the direction of the short side (y direction). Here, the lateral groove is a groove extending in the zy direction and having a thickness in the x direction. The remainder after removing the lateral grooves 16 is the lateral stripes 17. The metal material or plastic + inorganic material can be saved by the amount of the lateral groove 16. A set of transverse grooves 16 is a cavity. Costs can be reduced with a structure that can reduce material. It is inevitable that the strength will decrease accordingly. The horizontal strips 17 of the upper and lower upper pieces K and the second piece H correspond to the upper and lower sides and can transmit a load. FIG. 19 is a longitudinal sectional view taken along a plane including the horizontal stripes 17. Thereby, it turns out that the horizontal stripes 17 are contacting up and down.

The fitting mechanism is based on a combination of protrusions and fitting holes. On the back surface of the second piece H in FIG. 18, square hook protrusions L are provided for every nine of the lateral grooves 16 from the center. Corresponding to the hook projection L, a square-shaped fitting hole M is provided on the back surface of the upper piece K (FIG. 17) with a period of every nine horizontal grooves. When the hook protrusion L is inserted into the fitting hole M, the upper piece K and the second piece H are integrated. In addition, smaller ridge protrusions N are provided on the outer side of the back surface of the second piece H every nine horizontal grooves. The hook protrusion N fits exactly in one of the lateral grooves 16. The reason why the two types of protrusions L and N and the fitting hole M are used in combination is to make the fitting state stronger and more stable. FIG. 20 shows the mechanism of the fitting portion. Since the third embodiment is hollow by the amount of the lateral groove 16, the weight is reduced, and the material can be saved accordingly.

[Example 4 (with longitudinal grooves; chamfered; divided into two front and rear; FIGS. 23 to 26)]
In Example 4 described below, the base packing is cut at the longitudinal center line, and is divided into two in the front-rear direction to provide a hollow portion. There are longitudinal grooves 30 on the front and rear surfaces and chamfers 15 on the front and rear vertical ridge lines. These can be omitted. Example 4 provides a front and rear bifurcated base packing having a cavity. It is a structure in which the upper piece P and the second piece Q are fitted in the front and rear divided into two.

23 is a plan view of the basic packing of Example 4, FIG. 24 is a longitudinal sectional view in the longitudinal direction, FIG. 25 is a transverse plan view, and FIG. 26 is a longitudinal sectional view cut in parallel with the end face for showing the fitting structure. is there.

This basic packing is divided into front and rear parts, and consists of an upper piece P and a second piece Q. The upper piece P and the second piece Q are similar long rectangular plates. Since it is divided along the longitudinal center line, there is a fitting structure at that portion.

FIG. 25 shows a cross-sectional plan view of the fitted state. This best represents Example 4. There are a large number of longitudinal grooves 30 on the front surface 33 and the rear surface 34. A chamfer 15 exists on the ridgeline. Half of each of the anchor bolt through holes 32 is formed on each of the upper piece P and the second piece Q. Both the upper piece P and the second piece Q have a large number of parallel reinforcing ribs 39. The reinforcing ribs 39 are opposed to each other. A cylindrical receiving piece 37 is formed on the upper P. A cylindrical insertion piece 38 is also formed on the end piece Q. By inserting the insertion piece 38 into the receiving side 37, the upper piece P and the second piece Q are fitted. As shown in FIG. 26, both the insertion piece 38 and the receiving piece 37 are tightly fitted to join the upper piece and the second piece. A large space is created inside as shown in FIG. The existence of such a space saves material, reduces costs, and reduces the weight of the base packing. FIG. 21 is a perspective view showing an example of a state in which a concrete foundation 20 is hit on the ground and a foundation packing 1 is placed thereon in a wooden building. The shape and arrangement of the concrete foundation 20 vary depending on the layout of the house. On the concrete foundation 20, anchor bolts 28 are planted at appropriate positions. The foundation packing 1 of the present invention is sequentially placed on the concrete foundation 20. This is a basic packing having irregularities at the front and rear ends, and it is not necessary to temporarily fix all the basic packing with the anchor bolts 28.
