Description

  TECHNICAL FIELD The present invention relates to a foundation construction method and a termite prevention method, and in particular, a foundation construction method and a termite prevention method for performing a termite prevention treatment at a boundary position between a rising portion of a foundation and a dirt floor. About.

  In foundation construction of buildings, it is known to perform ant-repellent treatment at the boundary position between the rising part of the foundation and the dirt floor. Some conventional ant-proofing treatments apply a paste containing an ant-proofing component to the boundary position. In the case where such an ant protection method is adopted, a part of the part subjected to the ant protection treatment is peeled off by the operator inadvertently stepping on the paste before the paste is cured to a desired hardness. There was a risk of it. Also, the paste application operation depends on the skill of the operator, and there is a concern that the paste agent may not be applied at an appropriate application amount. Furthermore, since the paste application work and the work accompanying it are relatively time-consuming, it has been desired to save labor in the termite-proofing treatment.

  For the above problem, measures have been considered so far. For example, in the ant protection method shown in Patent Document 1, a square member is provided at a corner portion corresponding to the boundary position between the rising portion of the foundation and the floor between floors. A method of adhering a shaped ant protection member is disclosed. Here, the termite-proof member is obtained by applying or impregnating a termite-proof liquid or the like to wood, synthetic resin, metal, or foamed material. According to such an ant protection method, an ant protection method is realized regardless of the skill of the operator and with relatively little effort.

  In addition, as another countermeasure, there is an ant protection method shown in Patent Document 2, and in such an ant protection method, a groove is provided at a boundary position between the rising portion of the foundation and the floor between floors, and the ant protection material is provided in the groove. It is supposed to be filled with the converter slag. If such an ant protection method is used, it becomes possible to easily install a necessary amount of the ant protection material by filling the groove with the ant protection material.

<< About the first embodiment >>
First, the foundation work which concerns on 1st embodiment of this invention is demonstrated.
The foundation work according to the first embodiment is carried out in order to construct a foundation structure having a cloth foundation 1 as a foundation and an interstitial floor 2, and the foundation construction method and the ant-proof method of the present invention are applied. ing. That is, the foundation work which concerns on 1st embodiment has the process of constructing the cloth foundation 1, the process of constructing the dirt floor 2, and the process of performing an ant-proof process. Among these, in the process of constructing the fabric foundation 1, the fabric foundation 1 is constructed according to a known procedure. By this process, the fabric foundation 1 having the rising portion 1a rising along the vertical direction and the bottom portion 1b that is a foundation footing wider than the rising portion 1a is completed.

  Moreover, the process of constructing the dirt floor 2 is performed after the fabric foundation 1 is constructed or during construction, and is performed according to a known procedure. Specifically, in the process of constructing the interstitial floor 2, crushed stone is laid in the space for constructing the interstitial floor 2, strictly, the space surrounded by the rising portion 1 a of the fabric foundation 1, and concrete is placed thereon. Set up. And when the cast concrete hardens | cures to desired hardness, the floor 2 is completed.

  On the other hand, the foundation work which concerns on 1st embodiment has the characteristics in the process of giving an ant-proof process. Hereinafter, the procedure of the foundation work according to the first embodiment and the ant-proofing process performed in the foundation work will be described with reference to FIGS.

  The foundation work according to the first embodiment proceeds in the procedure shown in FIG. More specifically, the foundation work according to the first embodiment starts from the step of constructing the cloth foundation 1 (S001), and thereafter, concrete for the floor is placed (S004). The process is completed when the hardness is cured (S005). These contents are known as described above, and are common to general foundation works.

  On the other hand, in the foundation work according to the first embodiment, the ant proofing is performed before the time when the concrete constituting the upper layer of the interstitial floor 2 hardens to a predetermined hardness among the concrete cast for constructing the interstitial floor. Processing is to be performed. Here, the predetermined hardness means a hardness that can maintain a predetermined shape even when an external force is applied (in other words, a hardness in a situation where the fluidity is lost and the shape cannot be changed).

  The ant protection process performed in the first embodiment will be specifically described. As the ant protection process, as shown in FIG. 2, the position adjacent to the rising part 1a of the fabric foundation 1, more strictly, the rising The long rod-shaped ant protection body 3 is arranged at the corner portion that forms the boundary portion S between the portion 1a and the earth floor 2.

  The termite-proofing body 3 is a solid member having ant-proofing properties. In this embodiment, the termite-proofing body 3 is obtained by curing a paste agent P containing an termite-proofing component into a predetermined shape as shown in FIG. The paste agent P is the same as that applied to the wall surface of the rising portion 1a of the cloth base 1 in the conventional ant-proofing treatment. For example, an organic phosphorus agent, a carbamate agent, a pyrethroid agent, a boron compound, a fluorine compound The thing which carry | supported the ant-proof components, such as these on the support | carrier consisting of resin which has curability, can be utilized.

  In the first embodiment, as shown in FIG. 1, the above ant protection body 3 is prepared before placing the concrete for the floor 2 (S002). If it demonstrates concretely, the termite-proof body 3 will be shape | molded using the paste agent P mentioned above and the elongate case (henceforth case 4) shown in FIG. The case 4 is a container having an upper end as an open end and having a substantially U shape in a side view (a shape when viewed from the longitudinal end of the case 4). The paste agent P is put into the case 4 and cured so as to have a three-dimensional shape. Thus, by putting the paste agent P into the case 4 and curing it in the case 4, it becomes possible to easily mold the ant protection body 3 having a predetermined shape.

  In addition, when putting the paste agent P into the case 4, the paste agent P is filled up to the upper end of the case 4, and the paste agent P reaching the upper end is made flat with a scissors or the like. As a result, when the paste agent P is cured to a predetermined hardness and the ant protection body 3 is completed, a flat surface is formed on the upper end surface of the ant protection body 3 as shown in FIG.

  After preparing the termite-proof body 3 in the above-described procedure, concrete for the floor is placed, and then the above-mentioned termite-proof body 3 is arranged at a predetermined position (S004). This process S004 is performed during the period until the concrete which comprises the upper layer part of the floor 2 in the placement concrete 5 hardens | cures to predetermined | prescribed hardness. During this period, ant-proofing is performed in a range (that is, a location that will become the boundary portion S in the future) that forms a boundary with the rising portion 1a of the fabric foundation 1 in the concrete placement region that forms the upper layer portion of the floor 2 Embed body 3.

  That is, in the first embodiment, as shown in FIG. 4, the position of the cast concrete 5, that is, the rising portion of the fabric foundation 1, after the concrete for the floor 2 is placed and hardened. The ant defense body 3 is embedded at the boundary position with 1a. With such an ant-proofing treatment, it can be easily applied without requiring a particularly skilled skill, and it is not necessary to wait for the setting concrete 5 to harden. It can be shortened.

  Further, when embedding the ant-proof body 3 in the cast concrete 5, the upper end surface of the ant-proof body 3 and the upper end surface of the inter-story floor 2 are obtained when the concrete forming the upper layer of the inter-story floor 2 is cured to a predetermined hardness. The ant protection body 3 is embedded in the cast concrete 5 so that the That is, the ant-proof body 3 is arranged so that the upper end face of the ant-proof body 3 and the upper end face of the dirt floor 2 are at the same level. As a result, it becomes difficult for the ant-proof body 3 to stand out, and it is possible to prevent the ant-proof body 3 from interfering with the foundation work.

  Furthermore, when embedding the ant-proof body 3 in the cast concrete 5, the ant-proof body 3 is in a state where the upper end surface forming a flat surface is located on the upper end side of the case 4 and is exposed, and in this state, The ant body 3 is embedded in the cast concrete 5 together with the case 4. Thus, the function of the ant-proof body 3, that is, the ant-proof effect is appropriately exhibited by the upper end surface of the ant-proof body 3 being an exposed surface. In addition, by embedding the ant-proof body 3 together with the case 4 in the casting concrete 5, the ant-proof body 3 can be appropriately arranged while maintaining the shape of the ant-proof body 3. Thereby, arrangement | positioning of the termite-proof body 3 can be performed more smoothly.

  In addition, in 1st embodiment, although the termite-proof body 3 is embedded in the position in the case of the placement concrete 5 over the outer periphery whole range of the placement area | region of the placement concrete 5, this some ant-proof body 3 is Are arranged so as to be continuous with each other. In such a configuration, a gap is inevitably generated between the termite-proof bodies 3, but the paste agent P may be directly injected into the gap to fill the gap.

  Further, in the present embodiment, the case 4 having a substantially U shape in side view is used. However, it is preferable that the side wall of the case 4 is removable. More specifically, in the case 4, in the ant body 3 made of a paste agent that has been cured to some extent, it is in a position adjacent to a surface (corresponding to one side surface) that is closest to the rising portion 1 a of the fabric foundation 1. The side wall should be removable. If the side wall of the case 4 is removable as described above, the ant protection body 3 formed in the case 4 can be removed by removing the side wall after the paste agent put into the case 4 is cured to some extent. One side is exposed.

  And when embedding the ant-proof body 3 in the placement concrete 5, the upper end surface is exposed at the upper end side of the case 4, and one side surface is exposed by removing the side wall of the case 4. The termite-proof body 3 is disposed so that the one side surface faces the rising portion 1 a of the fabric foundation 1. More precisely, the termite-proof body 3 is arranged so that the exposed one side surface is in contact with the rising portion 1a. Thereby, the termite-proof body 3 comes closer to the rising portion 1a, and as a result, the termite-proofing process is more appropriately performed.

  In addition, about the side wall of case 4, it is good also as the whole being removable from the case main body (the part except the side wall in case 4), but the part including an upper end part at least can be removed in the side wall. It only has to be. That is, in the step of arranging the termite-proof body 3, the upper end surface is exposed at the upper end side of the case 4, and the upper region in one side surface is removed at least including the upper end portion of the side wall of the case 4. It is good also as arrange | positioning the termite-proof body 3 in the state exposed by (1) so that the upper area | region of the exposed one side may oppose the standing part 1a.
