Description

  The present invention relates to an improvement in building materials, and more particularly, to a breathable base packing that has sufficient support strength, ensures a ventilation path, increases ventilation capacity, and uses less material. Is.

  As is well known, a packing material is laid between the foundation of the building and the foundation, and ventilation under the floor can be performed by a vent hole provided in the packing material.

  In addition, conventionally, there is a type that uses such a packing material to ventilate not only under the floor but also between exterior exterior wall materials (see, for example, Patent Document 1).

  However, in such a packing material, since a portion protruding upward is formed, a step is generated by this portion, and when packing materials are overlapped with each other, there is a problem that the packing material becomes bulky during transportation. is there.

  In addition, since this projecting part is molded only on the side edge of one side, the installation direction is limited, and it is not possible to exchange the arrangement between the inside and outside of the foundation, and it is unsatisfactory that it is inconvenient to use. There is.

Furthermore, in conventional ventilated underfloor structures, floor plate support beams such as large pulls are often provided on the sides of the base, and when the floor plate support beams are installed, the bottom surface level of the base and the floor plate support beams Therefore, if the floor support beam level is low, there is a risk that the end of the beam will block the ventilation hole, and construction accuracy is required. Results in compulsion.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described in more detail with reference to the drawings specifically shown as follows.

  An embodiment of the present invention will be described with reference to FIGS. In the figure, a packing material 1 is a member interposed between a foundation B of a building and a base 2, and in this embodiment, a mixture of polypropylene and calcium carbonate is used as a material to be used.

  First, as shown in FIG. 1, a longitudinal plate-like main body 10 is provided with a plurality of openings 11, 11. By doing so, the material used can be reduced, and an anchor bolt protruding from the top end of the foundation B can be inserted into the opening 11.

  Further, the upper surface side 12 of the main body 10 is formed in a flat plate shape, and from the upper surface side 12, the concavo-convex walls 13, 13... Are vertically hung in a comb-like shape (continuous T-shape) vertically downward. A plurality of ventilation holes 14, 14... Penetrating in the width direction are continuously formed between the adjacent uneven walls 13, 13 (see FIG. 2).

  At this time, the protruding portions 13a, 13a,... Of the concavo-convex walls 13, 13 are protruded from the long side portions of the main body portion 10, respectively. Although this dimension is not specifically limited, For example, about 15 mm of the protrusion part 13a is preferable with respect to the full length 120-170 mm of the width direction of the main-body part 10. FIG.

  3, when a plate-like outer wall base material 3 is erected on the outer surface 21 of the base 2, the lower end portion 31 of the outer wall base material 3 is connected to the uneven walls 13, 13,. The outer wall base material 3 can be placed on the upper surface of the projecting portions 13a, 13a. Therefore, in the gap between the outer wall base material 3 and the outer wall exterior material 4, it is possible to vent upward from between the projecting portions 13a and 13a communicating with each other.

  In addition, as shown in FIG. 3, in the case where a floor plate support beam 6 such as an overdraw or joist is attached in a horizontal state inside the base 2 placed on the packing material 1. In the state where the edge 61 of the floor board support beam 6 is in contact with the inner side surface 22 of the base, the lower end surface of the floor board support beam 6 is placed on the upper surface of the protrusions 13a, 13a. It can be placed. With this configuration, the end of the floor board support beam 6 does not interfere with and block the ventilation hole 14.

  A plurality of ventilation holes 13, 13... Penetrating in the width direction are continuously formed at predetermined intervals on the long side of the lower surface side 12 of the main body 1. In this way, an air passage between the outside and the floor can be secured.

  In the present embodiment, the upper surface area of the protruding portions 13a, 13a,... Of the concavo-convex walls 13, 13,. Therefore, it is preferable to mold into a size that is not recessed and not dented, and the strength of the entire ventilation structure can be improved.

  Furthermore, in this embodiment, as shown in FIG. 3, the hollow part 13b can be shape | molded inside the uneven | corrugated wall 13 of the packing material 1, and a material to be used can be reduced. In addition, on the structure where the concavo-convex wall 13 is suspended in a comb-like shape, even if this configuration is adopted, the load from the base is received in the axial direction of the concavo-convex wall 13, so that the support strength can be greatly reduced. Absent.

  Furthermore, in the present embodiment, the packing material 1 can be formed symmetrically with the center line extending in the longitudinal direction as an axis, and can be used even if the arrangement of the inner side and the outer side of the foundation is interchanged. It is not necessary to check the direction one by one and it is easy to use.

  Further, in the present embodiment, a through hole 15a through which a fastening screw can be inserted is formed over the bridge portion 15 between the openings 11 and 11 on the upper surface of the main body portion 10 of the packing material 1, and this can be formed. The base packing and the foundation can be securely fixed by screwing the fixing screw.

  Further, the projection 15b can be provided on the upper surface of the bridging portion 15 between the openings 11 and 11 on the upper surface of the main body portion 10, and can be cut into the base to prevent lateral displacement and the like. Furthermore, since the base packing of the present embodiment is used by being connected in the longitudinal direction, the concave and convex portions 16 can be formed on the side end portions of the main body portion 1 and can be easily positioned.

  Moreover, as shown in FIG. 4 and FIG. 5, in this embodiment, the uneven walls 13 and 13 of the packing material 1 can be connected by the connection part 13c. By constituting in this way, the warpage of the main body 10 during transportation is prevented and the form is stabilized, and the strength can be ensured even in the event of an earthquake roll. .

  Furthermore, in the present embodiment, positioning protrusions 13d for confirming and aligning the inking reference line drawn on the mounting surface may be formed on the opposing surfaces of the uneven walls 13 and 13 of the packing material 1. it can. When placing the foundation packing on the foundation, the foundation cannot be stably installed unless the positioning is performed securely. Therefore, by configuring in this way, the ink line drawn on the foundation is used. It can be constructed while checking, and it is very convenient.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the “Claims”. The opening 11 formed on the upper surface of 10 may be one that is open only at one side end, or may be open at both side ends, By appropriately combining the different formation positions of the opening 11, it is possible to accurately match the position of the opening 11 and the installation position of the anchor bolt protruding to fix the base from the top of the foundation. it can.

  Although not shown, it is possible to make it difficult to slip by forming an uneven knurl on the surface of the upper surface side 12 (the upper surface of the bridging portion 15) of the main body 10, and any of these are within the technical scope of the present invention. Belongs.
