Description

  The present invention relates to, for example, a long building foundation packing that is continuously interposed between a fabric foundation and a building foundation.

  Conventionally, a building foundation packing interposed between a fabric foundation and a base of a building is conventionally formed into a block body having a length of about 20 cm, for example. A gap was formed between the foundation and the foundation to allow underfloor ventilation. However, the construction of the block body is troublesome because it is necessary to individually specify the arrangement position in consideration of the relationship with the anchor placed on the foundation.

  Such problems can be solved by continuously arranging long building foundation packings, but it is necessary to provide ventilation holes in the packing itself, and proposals have been made to take such measures. Yes. For example, in order to ensure a sufficient amount of ventilation, a long building foundation packing has been proposed in which a number of ventilation holes extending in the width direction are formed in the packing body, and the upper surface or lower surface of the ventilation holes are formed open. (For example, refer to Patent Document 1).

  However, even in the long construction foundation packing of the conventional example as described above, in order to adjust the corresponding position of the insertion hole through which the anchor placed in the foundation is inserted, the positions of the adjacent construction foundation packings There was a need to adjust. For example, when the interval between the building foundation packings is increased, the adjacent end portions may be separated from each other. If it does so, an antifungal effect will be lost. Further, in order to close the gap, the packing must be cut, but the cutting operation is troublesome.

  This invention is made in view of such a situation, and it aims at providing the basic | foundation packing for a building which can cut | disconnect a packing main body easily and can obtain a favorable fender effect.

In the building foundation packing according to the present invention, an insertion hole for vertically inserting an anchor placed on the foundation is formed in the center of the top plate of the long packing body, and the insertion hole is sandwiched between the insertion holes. In the lower part of the top plate on both sides, a vertical wall is formed in the width direction at a predetermined interval in the longitudinal direction, and a ventilating opening extending in the width direction is formed between the vertical walls. The packing body has a thickness that can be cut by folding the top plate between the vertical walls, and is cut between the vertical walls as the packing body is folded and cut. Accordingly, the reinforcing bars arranged so as to be separated from the top plate are formed to extend in the longitudinal direction.

In the building foundation packing according to the present invention, the packing in each of the longitudinal ends of the body, fitting the small protrusion for restraining the width direction of the relative displacement of the packing body each other are connected to each other And a fitting small recessed part may be formed.

  In the building basic packing according to the present invention, kerfs may be formed on the upper surface of the packing main body in the width direction at predetermined intervals in the longitudinal direction.

  According to the building foundation packing according to the present invention, it is easy to match the dimensions on-site by cutting. In addition, a reinforcing bar that also serves as a fender is passed between the vertical walls formed in the width direction of the packing body in the longitudinal direction, making it easy to ensure the structural strength of the packing body and without impairing the air permeability Good antifungal effect can be obtained.

  As shown in these drawings, an insertion hole 2 for inserting an anchor placed on the foundation is formed in the center portion of the packing body 1 in the vertical direction, although illustration is omitted. As shown in FIG. 1, the periphery of the insertion hole 2 is surrounded by a top plate 3, and on both sides of the bottom surface sandwiching the insertion hole 2 of the top plate 3, as shown in FIG. A vertical wall 4 is formed in the width direction, and a ventilation opening 5 extending in the width direction is formed between the vertical walls 4 and 4. And between the vertical walls 4, 4, a reinforcing bar 6 that also serves as a fender is formed so as to be passed in the longitudinal direction (see FIG. 2A), and the top plate is placed on the reinforcing bar 6. 3, a longitudinal groove 6a is formed that extends in the longitudinal direction. The reinforcing bar 6 divides the above-described ventilation opening 5 into upper and lower parts, but secures an opening area for ventilation of 300 square centimeters or more per 4 m.

  On the other hand, at the middle equivalent position between the vertical walls 4 and 4 on the upper surface of the top plate 3, kerfs 7 for cutting the main body are formed in the width direction at predetermined intervals in the longitudinal direction. This kerf 7 is used as a starting point when bending and cutting at the time of dimension adjustment. For example, when the top plate 3 has a thickness of 3 mm, it is formed in a V shape with a depth of about 1 mm. It is preferable to do this. Even if the cut grooves 7 of this degree are formed, the required strength and rigidity of the packing body 1 can be sufficiently ensured.

  At both ends in the longitudinal direction of the packing main body 1, fitting portions 8 and 9 for restricting the relative displacement in the width direction between the mutually connected packing main bodies and allowing the relative displacement in the longitudinal direction are provided in the longitudinal direction. It is formed so as to be freely detachable in the direction. Specifically, a fitting convex portion 8 is formed at one end of the packing body 1 and a fitting concave portion 9 is formed at the other end. Also in the fitting convex portion 8, the vertical walls 4, 4 are provided at the lower part of the top plate 3, and a ventilation opening 5 is formed between the vertical walls 4, 4 that extends in the width direction. Further, a small fitting convex portion 10 and a small fitting concave portion 11 are formed on both sides of the fitting convex portion 8 and the fitting concave portion 9, respectively, and when the packing bodies 1, 1 are brought into contact with each other, they face each other. The fitting small convex portion 10 and the fitting small concave portion 11 are fitted to each other.

  A partition portion 3a extending in the width direction is formed between the insertion holes 2 and 2, and the vertical grooves 6a and 6a are formed between the partition portions 3a and 3a, and the outside of the vertical grooves 6a and 6a. The top plate 3 is provided with guide lines 3b and 3b formed in the shape of small grooves that pass through in the longitudinal direction (see FIG. 1A). Further, a shallow groove 3c indicating a center line is formed at the center of the upper surface of the partition portion 3a, and a total of three nail holes 3d are formed on one side of the partition portion 3a on the center line 3c ( (See FIGS. 3 and 4).

  In addition, a pair of protrusions 3e (about 2 mm high) for preventing misalignment is formed at both side positions sandwiching the center line 3c on the upper surface of the partition 3a (a total of 7 pairs). As shown in FIGS. 1B, 1C and 4, the partition portion 3a described above has a pair of side walls 3f and 3f formed relatively thick at the lower portion thereof to obtain necessary strength and rigidity. Between the side walls 3f and 3f, a ventilation bar 3g is formed between the side walls 3f and 3f. The building foundation packing configured as described above can be formed by integral molding of resin.

  In the building basic packing configured as described above, the packing bodies 1 and 1 are connected to each other in a fitting state as shown in FIGS. 5A and 5B by fitting the fitting portions 8 and 9 together. be able to. That is, in the case of FIG. 5 (a), the small fitting portion 10 and the small fitting concave portion 11 of both packing bodies 1, 1 are fitted together (the two packing bodies 1, 1 are in contact with each other). ). In this state, the relative displacement in the width direction between the packing bodies 1 and 1 is restricted. However, in the fitting portions 8 and 9, relative displacement in the longitudinal direction is allowed. For example, in order to adjust the position of the insertion hole 2 with respect to the anchor placed on the foundation, FIG. As shown, the fitting portions 8 and 9 can be relatively separated from each other up to the separation interval S1.

  Even in such a separated state, the relative displacement in the width direction between the packing bodies 1 and 1 is constrained, so that the packing body 1 and 1 can be stably maintained without being displaced between the foundation and the foundation of the building. ... can be inserted continuously, and good workability can be obtained during construction on site. Further, since the discontinuous portion is not formed, the fender effect is not lowered. When the position of the packing bodies 1 and 1 cannot be adjusted even in the separated state as described above, the packing body 1 is moved with bare hands using the kerf 7 formed on the top surface of the top plate 3 as an opening for breaking. Since it can be easily cut by bending, the length of the packing body 1 may be adjusted to be appropriately shortened.

  6 (a) to 6 (c) show different embodiments, and in this example, fitting recesses (fitting portions of the present invention) 9 and 9 are formed at both ends of the packing bodies 1 and 1, and both of them are formed. A fitting member 21 for fitting into the fitting recesses 9 and 9 is formed. The fitting member 21 is provided with vertical walls 4, 4 at the lower part of the top plate 3, as shown in FIG. A ventilation opening 5 extending in the width direction is formed, and a reinforcing bar 6 also serving as a fender is provided between the vertical walls 4 and 4 so as to pass in the longitudinal direction. A shallow groove 3c indicating a center line is formed in the longitudinal direction at the center of the top surface of the top plate 3. In addition, the same code | symbol is attached | subjected about the same or equivalent member as previous embodiment, and description is abbreviate | omitted.

  In this case, when the packing bodies 1 and 1 are brought into contact with each other, although not shown, the fitting member 21 is fitted into the insertion holes 2 and 2 and the fitting small convex portions 10 facing each other. The fitting small recesses 11 are fitted to each other. On the other hand, when the packing bodies 1 and 1 are separated as much as possible, they can be separated to the separation interval S2, as shown in FIG. In this case, the separation interval can be considerably increased as compared with the separation interval S1. Only the fitting recesses 9 and 9 need be formed in the packing body 1, and a mold by integral molding of a resin material can be manufactured at low cost.

  Note that the present invention is not limited to the embodiment, and it is free to make design changes or improvements as necessary, as long as it does not depart from the gist of the invention. For example, the packing body 1 The details of the shape may be appropriately changed in design, and the reinforcing bars may be provided in a plurality of stages. Further, in different embodiments, if the fitting member 21 is prepared in a plurality of different lengths, the degree of freedom in adjusting the separation distance between the packing bodies 1 and 1 can be further increased.
