Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection member for foundation packing that connects foundation packings that are arranged and used between the foundation and foundation of a building.

BACKGROUND ART In recent years, in buildings such as houses, a foundation packing construction method in which a foundation packing is laid between foundations has been widely used. In this foundation packing construction method, end portions of long foundation packings are connected to each other and arranged continuously on the foundation. As a connecting member (joiner) for connecting the basic packings, a clip type having a U-shaped cross section has been proposed (see Patent Document 1). The connecting member connects the basic packings by hooking them from above into recesses provided on the upper surfaces of both end portions of the basic packings.

However, in the connection member described in Patent Document 1, since the base packing is hooked from above when connecting the base packing, the connection member slightly protrudes from the upper surface of the base packing and interferes with the base. occur. In addition, due to this protrusion, an unevenness (gap) occurs between the foundation packing and the base, and when the unevenness occurs, an adjustment plate (thin plate) inserted between the foundation packing and the base is used. spacers) or interfere with the work of inserting the adjustment plate. Furthermore, since the connecting member is hooked from above the foundation packing, there arises a problem that the connecting member cannot be attached to the foundation packing of an existing building in which the base has already been placed on the foundation packing.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to connect basic packings together without interfering with a base or an adjusting plate, and to connect the basic packings together even when the base is placed on the basic packings. It is an object of the present invention to provide a connecting member for a base packing that can

It is

According to this, of two basic packings arranged adjacently on the foundation, one inserting member is inserted into the concave portion of one of the basic packings, the other inserting member is inserted into the concave portion of the other basic packing, and the other inserting member is inserted into the concave portion of the other basic packing. It is possible to connect the ends of the two basic packings in the longitudinal direction by inserting and attaching them from one side surface side and connecting these inserting members with the holding member. Therefore, the base packings can be connected to each other without causing the connecting member to interfere with the base or the adjustment plate, and the base can be connected before placing the base on the base packing and after placing the base on the base packing. It is possible to connect foundation packings with a connecting member in various situations such as a state of being placed on foundation packing (for example, foundation packing of an existing building). Furthermore, by connecting the foundation packings together from the side surfaces, it is possible to effectively prevent the ends of the foundation packings from being displaced in the horizontal direction, thereby further improving the earthquake resistance of the building.

In the present invention, it is preferable that at least one of the insertion member and the holding member has elasticity. As a result, if unevenness occurs on the foundation, if the basic packing is cut or broken and used, or if there is a misalignment in the arrangement of the basic packing, one of the basic packings to which one of the insertion members is inserted and the recess of the other base packing into which the other insertion member is inserted, even if there is a slight error in the distance, the elasticity of at least one of the insertion member and the holding member The error can be absorbed by bending, and the basic packings can be connected to each other.

Further, in the present invention, it is preferable that the one insertion member can be attached and held with respect to the holding member from a side surface along the one direction. As a result, the inserting member can be mounted from the side surface of the holding member after determining the mounting position of the holding member, so that the work of mounting the connecting member to the base packing can be made easier. Further, even after the connecting member is attached to the basic packing, the insertion member can be added. Further, it is more preferable that the insertion member can be detachably attached from the side surface of the holding member. As a result, even after the connecting member is attached to the basic packing, the insertion position of the insertion member can be changed or the insertion member can be replaced.

Moreover, in the present invention, it is preferable that the holding member has elasticity, and the insertion member has an engaging claw that engages with the basic packing. As a result, each insertion member inserted into the concave portion of the basic packing can be pulled back by utilizing the elastic bending of the holding member. In addition, elasticity in the present invention is a broad concept including material and shape.

Further, in the present invention, the one insertion member has teeth formed on the base portion on the side opposite to the tip to be inserted into the recess, and the holding member is arranged along the one direction, It has a plurality of teeth that can mesh with the teeth of the one insertion member, and the holding position for holding the one insertion member is aligned with the teeth of the one insertion member in the one direction. The change is preferably made by changing the meshing position of the holding member with the teeth. As a result, if unevenness occurs on the foundation, if the basic packing is cut or broken and used, or if there is a misalignment in the arrangement of the basic packing, one of the basic packings to which one of the insertion members is inserted Even if there is a slight error in the distance between the recess of the other base packing and the recess of the other base packing into which the other insertion member is inserted, the distance between the plurality of insertion members can be easily changed to an arbitrary distance. , and the basic packings can be effectively connected to each other.

Further, in the present invention, it is preferable that the one insertion member has a restriction portion that restricts vertical movement with respect to the holding member. This makes it difficult for one of the insertion members to come off from the holding member due to pitching of an earthquake.

Further, in the present invention, it is preferable that the recess provided in the base packing is a ventilation hole for underfloor ventilation, and the thickness of the holding member is smaller than the height of the ventilation hole. Accordingly, by attaching the connection member to the basic packing, it is possible to suppress deterioration of the ventilation performance of the basic packing.

Further, in the present invention, the holding member has a first holding portion and a second holding portion extending along the one direction, and one end portion of the first holding portion and the one end of the first holding portion extend in the one direction. It is preferable that the other end of the second holding portion is detachably connected. Accordingly, by removing the second holding portion from the first holding portion, the length of the holding member in one direction can be adjusted.

Moreover, in the present invention, it is preferable that the first holding portion is configured to be horizontally rotatable with respect to the second holding portion while being connected to the second holding portion. As a result, even if the base packings are arranged non-linearly rather than linearly, they can be attached to two adjacent base packings.

According to the basic packing connecting member of the present invention, one of the two basic packings arranged adjacently on the foundation has one inserting member inserted into the recess of one of the basic packings, and the other inserting member is inserted into the recess of the other basic packing. By inserting the insertion members from one side of the base packing and connecting them with the holding member, it is possible to connect the longitudinal ends of the two base packings. becomes. Therefore, the base packings can be connected to each other without causing the connecting member to interfere with the base or the adjustment plate, and the base can be connected before placing the base on the base packing and after placing the base on the base packing. It is possible to connect foundation packings with a connecting member in various situations such as a state of being placed on foundation packing (for example, foundation packing of an existing building). Furthermore, by connecting the foundation packings together from the side surfaces, it is possible to effectively prevent the ends of the foundation packings from being displaced in the horizontal direction, thereby further improving the earthquake resistance of the building.

A building structure 100 using a connecting member for foundation packing according to an embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

As shown in FIG. 1, the building structure 100 in this embodiment includes a long foundation 1 (for example, a cloth foundation), a plurality of foundation packings 10, a wooden foundation 2, and a connecting member that connects the foundation packings 10. 20. In this embodiment, as shown in FIG. 1, the right front side of the foundation 1 is outdoors, and the left back side of the foundation 1 is indoors, which is also the underfloor space S. As shown in FIG. The plurality of foundation packings 10 extend long along the longitudinal direction A (one direction) of the foundation 1, and are arranged on the foundation 1 in a state of being connected in series in the longitudinal direction A by connecting members 20. there is The base 2 is arranged on these base packings 10 so as to sandwich a plurality of base packings 10 with the base 1, and is elongated in the longitudinal direction A.

The base 1 is composed of a footing 1a and a rising portion 1b erected upward from the footing 1a. The foundation 2 and a plurality of foundation packings 10 are fixed on the rising portion 1b by anchor bolts, square washers and nuts (none of which are shown) implanted in the foundation 1. As shown in FIG.

Next, the basic packing 10 will be described below with reference to FIG. The base packing 10 normally has a thickness in the vertical direction C of 10-30 mm. Also, the width is 70 to 200 mm, which is determined according to the width of the base 2 . The length in the longitudinal direction A is as long as about 500 to 2000 mm. The material is synthetic resin. In this embodiment, a polypropylene resin containing a filler is used, but it is not particularly limited and may be composed of another synthetic resin.

On both side surfaces 10a and 10b along the longitudinal direction A of the base packing 10, as shown in FIG. 12 are formed. Each air hole 12 constitutes a recess recessed inward from both side surfaces 10 a and 10 b of the basic packing 10 . Since the base packing 10 receives a compressive load in the vertical direction C during use, it is designed to ensure the required compressive strength when forming the ventilation holes 12 . In this embodiment, the vent holes 12 have a rectangular cross-sectional shape and are arranged side by side in the longitudinal direction A, but they may have other cross-sectional shapes such as a circular shape and a rhombic shape.

As shown in FIG. 2, the base packing 10 is formed with a plurality of holes 16 penetrating in the vertical direction C for the anchor bolts to pass through. A plurality of holes 16 are formed along the longitudinal direction A. As shown in FIG. In addition, on both ends of the basic packing 10 in the longitudinal direction A, a convex portion 17 and a concave portion 18 for positioning when connecting the basic packings 10 are formed, respectively, and the basic packings 10 are used by connecting them in series. It's getting easier.

Next, a basic packing connecting member 20 for connecting the basic packings 10 will be described below with reference to FIGS. 2 to 7. FIG. 2 to 7, the connecting member 20 will be described by reflecting the longitudinal direction A, width direction B and vertical direction C shown in FIG. As shown in FIGS. 2 and 3, the connecting member 20 has two insertion members 30 and a holding member 50 that holds the insertion members 30 side by side along the longitudinal direction A. . The insertion member 30 and the holding member 50 in this embodiment are made of polypropylene resin and both have elasticity. The materials of the insertion member 30 and the holding member 50 are thermoplastic resins such as PE (polyethylene), PVC (polyvinyl chloride), PS (polystyrene), and ABS (acrylonitrile butadiene styrene), thermosetting resins such as phenol and epoxy. It may be a flexible resin, aluminum, stainless steel, iron or other metal, and is not particularly limited.

As shown in FIG. 2, the insertion member 30 is inserted into the ventilation hole 12 from the side 10a side (indoor side) and attached to the base packing 10. As shown in FIG. The insertion member 30 has a base portion 31 and a pair of extending portions 32 extending in parallel from the base portion 31 along the width direction B, as shown in FIG.

As shown in FIGS. 3 and 4, the base portion 31 has a substantially rectangular parallelepiped shape extending along the vertical direction C, and one side surface 31a of the base portion 31 (facing the side surface 10a when attached to the base packing 10). A pair of extending portions 32 are formed projecting from the upper half portion of the side surface 31a). A plurality of teeth 33 protruding along the width direction B and arranged side by side in the longitudinal direction A are formed on a lower half portion of one side surface 31a of the base portion 31 . Each tooth 33 is formed in a mountain shape with a pointed tip. A restricting portion 34 is formed at the lower end portion of the base portion 31 . The restricting portion 34 is arranged so as to protrude toward the distal end side of the extension portion 32 from the distal end of the tooth 33 . As a result, as shown in FIG. 3, in a state in which the insertion member 30 is held by the holding member 50, the movement of the insertion member 30 in the vertical direction C with respect to the holding member 50 can be restricted. A concave portion 31b opening upward is formed on the upper surface of the upper half portion of the base portion 31 .

As shown in FIG. 3 , the pair of extending portions 32 has a connecting portion 35 that connects the lower end portions between the base portion 31 and the center in the width direction B. As shown in FIG. Further, two engaging claws 32b are formed on the outer side surface 32a of each extending portion 32 on the distal end side of the center in the width direction B. As shown in FIG. The engaging claw 32b is formed to protrude outward from the outer surface 32a, and has a tapered surface 32c on the tip side and an engaging surface 32d on the base 31 side. The pair of extending portions 32 are configured such that when the inserting member 30 is not inserted into the ventilation hole 12 of the basic packing 10, the distance between the extending portions 32 slightly increases toward the tip. As a result, when the insertion member 30 is inserted into the ventilation hole 12 , the pair of extension portions 32 tend to spread outward, and the engagement surface 32 d of the engagement claw 32 b becomes the inner surface 10 c of the basic packing 10 . (sides defining hole 12). Further, of the two engaging claws 32b of each extending portion 32, the tip of the engaging claw 32b on the tip side is located slightly outside the tip of the engaging claw 32b on the base portion 31 side. Therefore, even if the width of the basic packing 10 is larger than that shown in FIG. 2 or the width of the hole 16 is smaller than that shown in FIG. 30 can be inserted into the vent hole 12 .

The holding member 50 is composed of a plate-shaped bar member elongated along the longitudinal direction A, as shown in FIGS. The thickness of the holding member 50 in the vertical direction C is smaller than the height of the vent hole 12 . Two notches 51 and 52 are formed in the lower half of the holding member 50 . As shown in FIG. 7, the notch 51 extends long along the longitudinal direction A in the lower part in FIG. 7 including the center in the width direction B between both ends of the holding member 50. there is The notch 52 is formed at the right end as shown in FIG. As shown in FIG. 5, the upper half of the holding member 50 is formed with a notch 53 at the left end.

A wall portion 52a formed by a notch portion 52 is formed at the right end portion of the holding member 50. As shown in FIG. A circular through hole 52b penetrating in the vertical direction C is formed in the right end portion. The wall portion 52a is formed in an arc shape centering on the through hole 52b. A wall portion 53 a formed by a notch portion 53 is formed at the left end portion of the holding member 50 . A circular projecting portion 53b projecting in the vertical direction C is formed on the left end portion. The protruding portion 53b is formed in a size that can be just fitted into the through hole 52b. The wall portion 53a is formed in an arc shape centering on the projecting portion 53b. Thereby, it becomes possible to connect the two holding members 50 by fitting the protruding portion 53b of another holding member 50 into the through hole 52b of the one holding member 50 . At this time, since the arc-shaped wall portion 52b is formed on the one holding member 50, the other holding member 50 connected to the one holding member 50 can be moved horizontally (center passing through the center of the projecting portion 53b) with respect to the one holding member 50. ), the corner of the left end of another holding member 50 does not interfere with the wall 52b. Therefore, it becomes easier to cause the two holding members 50 to follow the basic packing 10 . That is, even if the two connecting members 20 are connected, they can be easily attached to the basic packing 10 .

A plurality of teeth 55 protruding along the width direction B and arranged side by side in the longitudinal direction A are formed in the upper half of the holding member 50 and facing the notch 51 in the vertical direction C. . Each tooth 55 is formed in a mountain shape with a sharp tip, and is configured to be meshable with the plurality of teeth 33 of the insertion member 30 . The holding member 50 holds the insertion member 30 in a state in which the teeth 33 of the insertion member 30 and the teeth 55 of the holding member 50 are engaged with each other. In other words, the holding position of the insertion member 30 by the holding member 50 is also the meshing position where the plurality of teeth 33 of the insertion member 30 and the plurality of teeth 55 of the holding member 50 mesh. Therefore, by changing the meshing position along the longitudinal direction A, the holding position of the insertion member 30 by the holding member 50 is also changed.

Next, the mounting situation when connecting two base packings 10 with the connecting member 20 will be described below. First, as shown in FIG. 2, the holding member 50 of the connecting member 20 is arranged along and across the side surfaces 10a of the two base packings 10 to be connected. At this time, the holding member 50 is arranged so that the plurality of teeth 55 of the holding member 50 are arranged on the side opposite to the basic packing 10 . Then, one of the two insertion members 30 is inserted into the ventilation hole 12 of the base packing 10 while engaging the plurality of teeth 33 of one of the two insertion members 30 with the plurality of teeth 55 of the holding member 50 . Insert 30. That is, one insertion member 30 is inserted into the ventilation hole 12 from the side surface (the side surface on which the teeth 55 are formed) along the longitudinal direction A of the holding member 50 . At this time, since the teeth 33 and 55 have a mountain shape with pointed ends, the teeth 33 and 55 are easily meshed with each other even when one of the insertion members 30 is inserted into the ventilation hole 12 . That is, the tips of the teeth 55 are arranged between the tips of the plurality of teeth 33, and when the teeth 33 and 55 approach each other, they are guided by the side surfaces (tapered surfaces) of the teeth 33 and 55, and the teeth 33 and 55 mesh. easier. In this way, one insertion member 30 is attached and held by the holding member 50 . Also, at this time, due to the contact between the tapered surface 32c of the engaging claw 32b on the distal end side and the inner surface of the vent hole 12, the pair of extending portions 32 bends inward. After that, the engaging claw 32b on the side of the base 31 is arranged in the hole 16 through the air hole 12, so that the engaging surface 32d of the engaging claw 32b is engaged with the inner side surface 10c, and one of the basic packings One insertion member 30 is inserted into 10 . At this time, one insertion member 30 may be inserted into one base packing 10 in a state in which one insertion member 30 is held by the holding member 50 in advance.

After that, while engaging the plurality of teeth 33 of the other insertion member 30 with the plurality of teeth 55 of the holding member 50 , the other insertion member 30 is inserted into the ventilation hole 12 of the other basic packing 10 . That is, the other insertion member 30 is inserted into the ventilation hole 12 from the side surface (the side surface on which the teeth 55 are formed) along the longitudinal direction A of the holding member 50 . At this time, since the teeth 33 and 55 have a mountain shape with pointed ends, the teeth 33 and 55 are likely to mesh with each other in the same manner as described above even when the other insertion member 30 is inserted into the ventilation hole 12. Become. Thus, the other insertion member 30 is attached and held by the holding member 50 . The other insertion member 30 is also inserted into the other base packing 10 in the same manner as the one insertion member 30 . At this time, the other insertion member 30 may be inserted into the other basic packing 10 while the other insertion member 30 is held by the holding member 50 in advance.

In the connecting member 20 in the above-described embodiment, each insertion member 30 is inserted into the second ventilation hole 12 from the end of the basic packing 10, but the insertion member 30 is held by the holding member 50. is configured to be variable in the longitudinal direction A. Therefore, the insertion member 30 may be inserted into any ventilation hole 12 in the longitudinal direction A as long as the ventilation hole 12 overlaps with the plurality of teeth 55 of the holding member 50 .

As described above, according to the connecting member 20 of the present embodiment, one of the two base packings 10 arranged adjacent to each other on the base 1 is inserted into the ventilation hole 12 (concave portion) of one of the base packings 10 . The other inserting member 30 is inserted into the ventilation hole 12 (concave portion) of the other basic packing 10 from one side surface 10a of the basic packing 10, and these inserting members 30 are inserted. By connecting with the holding member 50 , it is possible to connect the ends of the two basic packings 10 in the longitudinal direction A to each other. Therefore, it is possible to connect the base packings 10 to each other without causing the connecting member 20 to interfere with the base 2 or the adjustment plate, and the base 2 is placed on the base packing 10 before the base 2 is arranged on the base packing 10 . After placing the base 2 on the foundation packing 10 (for example, the foundation packing 10 of an existing building), the foundation packings 10 can be connected with the connecting member 20 in various situations. . Furthermore, by connecting the foundation packings 10 to each other from the side 10a side, it is possible to effectively prevent the ends of the foundation packings 10 from shifting in the horizontal direction, thereby further improving the earthquake resistance of the building. Note that the connecting member 20 of this embodiment may have three or more insertion members 30 .

The two insertion members 30 and the holding member 50 that constitute the connecting member 20 have elasticity. As a result, when unevenness occurs on the foundation 1, when the foundation packing 10 is used after being cut or broken, when the arrangement of the foundation packing 10 is misaligned, etc., one of the insertion members 30 can be inserted. Even if there is a slight error in the distance between the ventilation hole 12 of one base packing 10 and the ventilation hole 12 of the other base packing 10 into which the other insertion member 30 is inserted, the two insertion members Due to the elasticity of 30 and holding member 50, the error can be absorbed by bending, and the base packings 10 can be connected to each other.

As a modification, one or two of the two insertion members 30 and the holding member 50 forming the connecting member 20 may have elasticity. Also in this case, similarly to the above, the two insertion members 30 and the elastic member of the holding member 50 bend to absorb the error, and the basic packings 10 can be connected to each other. .

Also, the holding member 50 has elasticity, and the two insertion members 30 have engaging claws 32b. As a result, each insertion member 30 inserted into the ventilation hole 12 of the basic packing 10 can be pulled back by utilizing the bending due to the elasticity of the holding member 50, thereby reducing the loosening of the engagement of the locking claw 32b. be able to.

In addition, the insertion member 30 is formed with a plurality of teeth 33, and the holding member 50 is formed with a plurality of teeth 55 that can mesh with the plurality of teeth 33, and the holding position for holding the insertion member 30 is By changing the meshing position between the teeth 33 of the insertion member 30 and the teeth 55 of the holding member 50 in the longitudinal direction A, it is changed. As a result, when unevenness occurs on the foundation 1, when the foundation packing 10 is used after being cut or broken, when the arrangement of the foundation packing 10 is misaligned, etc., one of the insertion members 33 is inserted. Even if there is a slight error in the distance between the ventilation hole 12 of one base packing 10 and the ventilation hole 12 of the other base packing 10 into which the other insertion member 33 is inserted, the distance between the insertion members 30 can be easily changed to an arbitrary distance, and the basic packings 10 can be effectively connected to each other.

The insertion member 30 has a restriction portion 34 that restricts movement in the vertical direction C with respect to the holding member 50 . As a result, the insertion member 30 is less likely to come off from the holding member 50 due to pitching of an earthquake.

Further, the thickness of the holding member 50 in the vertical direction C is smaller than the height of the ventilation hole 12 of the basic packing 10 . As a result, even if the connection member 20 is attached to the basic packing 10, the holding member 50 does not entirely cover the ventilation holes 12 facing in the width direction B, so that deterioration of the ventilation performance of the basic packing 10 can be suppressed. .

As a modification, the connecting member 200 may be configured by connecting the two connecting members 20 described above. A connecting member 200 of this modified example will be described below with reference to FIG. The connecting member 200 of this modified example is composed of the two connecting members 20 described above, as shown in FIG. That is, one connecting member 20 (left side in FIG. 8) has a through hole 52b at one end (right side end in FIG. 8) of the holding member 50 (first holding portion), and the other connecting member 20 (right side in FIG. 8) is inserted into the through hole 52b. ) of the holding member 50 (second holding portion) of the second holding portion) is fitted to the projection 53b of the other end (the left end in FIG. 8) to connect the two connecting members 20, and the connecting member 200 of this modification constitutes In such a connecting member 200 , two holding members 50 are detachably connected to form one holding member 250 . Accordingly, by removing the other holding member 50 (second holding portion) from one holding member 50 (first holding portion), the length of the holding member 250 in the longitudinal direction (one direction) A can be adjusted. .

In addition, the two holding members 50 constituting the holding member 250 are configured so that the other holding member 50 can rotate in the horizontal direction with respect to the one holding member 50 in a mutually connected state. As a result, even when the base packings 10 are arranged non-linearly rather than linearly, they can be attached to two adjacent base packings 10 . Although the connecting member 200 in this modified example has four insertion members 30, it may have two or three insertion members 30, or may have five or more insertion members 30. You may have

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, in the above-described embodiment and modifications, the insertion member 30 is inserted into the through hole 12, but the insertion member 30 may be inserted into a non-penetrating recess. In other words, the insertion member 30 only needs to be able to be inserted into the recess provided on the side surface of the base packing. Further, the holding member 50 described above is configured such that the holding position of both of the two insertion members 30 can be changed in the longitudinal direction A, but only one of the insertion members 30 can be changed in the longitudinal direction A. , and only the other insertion member 30 may be fixed to the holding member 50 .

The holding member 50 only needs to be configured such that the holding position for holding the insertion member 30 can be varied in the longitudinal direction A, and is not particularly limited to a holding configuration based on meshing of the teeth 33 and 55 . In addition, the holding member 50 and the inserting member 30 described above are attached to the basic packing 10 so that they are difficult to remove (the holding member 50 is attached to the basic packing 10 and the inserting member 30 is attached to the basic packing 10). However, it is sufficient if the insertion member is supported so as to be slidable in the longitudinal direction with respect to the holding member, although the two are previously configured to be inseparable. At this time, it is sufficient that the insertion member can be fixed at an arbitrary position on the holding member in the longitudinal direction. The fixing structure at this time may be any fixing structure such as pin fixing.

The insertion member 30 may not have the engaging claw 32b. Also, the thickness of the holding member 50 in the vertical direction C may be equal to or greater than the height of the vent holes 12 and equal to or less than the thickness of the basic packing 10 . Further, the holding member 50 may be configured so that it cannot be connected to another holding member 50 .

Further, in the above-described embodiment and each modified example, the insertion member 30 and the holding member 50 have elasticity, but they may be made of hard resin or metal, and may not have elasticity. Furthermore, even with hard resin or metal, elasticity can be imparted by providing a thin or thin portion.
