Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ant proof structure between concrete soils.
[0002]
[Prior art and problems]
The ant-proofing treatment of the soil under the floor of the building is conventionally performed by spraying an emulsion-like chemical on the entire surface of the soil under the floor before hitting the soil concrete.
[0003]
However, this makes it difficult to adjust the schedule between the ant-proofing work and the earth-concrete casting work, and the soil surface treated with the ant-proofing is roughened by the earth-casting work after the ant-proofing work. There were problems, such as being sometimes.
[0004]
Therefore, recently, a granular material (for example, First Guard Granule (registered trademark) manufactured by Takeda Pharmaceutical Co., Ltd.) is used as an ant-proofing agent, and after the soil concrete is struck, the joint between the concrete cloth foundation and the concrete soil is used. An ant-repellent treatment method has been proposed in which the granular agent is laid on the concrete soil in the part.
[0005]
However, since this chemical is granular, it is easy to disperse. There was a problem that it was easily scattered around.
[0006]
In view of the conventional problems as described above, the present invention is capable of performing an ant-proofing process after pouring concrete between the soils, and in addition, between concrete soils where the ant-proofing work can be performed appropriately and easily. It is an object to provide an ant-proof structure.
[0007]
[Means for Solving the Problems]
The above-mentioned problem is that, in the boundary between the foundation and the concrete soil, a groove extending along the boundary is provided on the concrete soil, and an anti-anticide is disposed in the groove. Solved by ant-proof structure.
[0008]
In this ant-proof structure, focusing on the fact that one of the main paths of entry of termites from the underfloor soil is the boundary between the foundation and the concrete soil, ant-proof treatment is performed on that part, The ant-proofing treatment can be performed from the upper surface side of the soil, and therefore the concrete-concrete driving work can be performed prior to the ant-proofing work.
[0009]
In addition, at the boundary between the foundation and the concrete soil, a groove extending along the boundary is provided on the concrete soil, and an anti-anticide is arranged in the groove. Even if it consists of a chemical | medical agent, the chemical | medical agent can be hold | maintained to a groove | channel, Therefore, the construction of an ant-proof process can be performed appropriately and easily. In addition, an appropriate amount of the ant preventive agent can be arranged without being too much, and the waste of the ant preventive agent can be eliminated.
[0010]
Moreover, said subject is solved by the ant-proof structure in the concrete soil in which the elastic sealing material is provided in the joint part of a foundation and soil concrete.
[0011]
In this ant-proof structure, an elastic sealink material is provided at the joint between the foundation and soil concrete, which is one of the main routes of intrusion of termites from the underfloor soil. Intrusion can be prevented. The construction of the elastic sealant can be performed after the soil concrete has been driven in, the construction of the elastic sealant can be easily performed, and even if the seam between the foundation and the concrete soil opens over time, The sealing state can be maintained by the elasticity of the sealing material, and the intrusion of termites can be effectively prevented.
[0012]
By the way, another route of intrusion of termites and the like from the underfloor soil is a crack portion that is later generated by the shrinkage of the soil concrete. However, it is difficult to specify which part is cracked between concrete soils. In view of this, it is preferable to provide an inferior strength groove for causing cracks in advance, that is, to induce cracks, between the concrete soils, and to arrange an anti-anticide in the inferior strength groove.
[0013]
In this ant-proof structure, cracks caused by concrete shrinkage occur in poorly-strength grooves, and since an ant-proofing agent is placed in this groove, it is possible to reliably prevent the entry of termites and the like due to shrinkage of the soil concrete and cracks. Can do. Of course, in this structure, it is possible to drive the soil-concrete before the ant-proofing work, and the ant-proofing process can be carried out properly and easily because the ant-proofing agent only needs to be placed in the groove. .
[0014]
In addition, when a poor strength groove that causes cracks to occur in advance is provided between the concrete soils, and an elastic sealing material is provided in the weak strength groove, this elastic sealing material prevents the entry of termites through the cracked portion. Can be surely prevented.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0016]
In the embodiment shown in FIGS. 1 (a) and (b), 1 is a concrete cloth foundation, 2 is an underfloor soil, 3 is a concrete soil, and the concrete soil 3 is placed on the underfloor soil 2 after the foundation 1 is constructed. It is formed by hitting concrete.
[0017]
In the concrete soil 3, a groove 4 having a predetermined cross-sectional square shape extending along the boundary portion is formed at a boundary portion that is a joint portion with the fabric foundation 1. The groove 4 can be formed by, for example, a method in which a formwork is installed at a groove formation scheduled place before the soil concrete 3 is struck, the soil concrete 3 is driven, and demolded. The depth dimension and width dimension of the groove 4 are determined by the type of the termite-proofing agent, but when a commercially available granular termiticide is used, the groove depth is about 1 cm and the groove width is about 5 to 10 cm, for example. It is good to.
[0018]
The groove 4 is filled with a granular ant protection agent 5. The arrangement | positioning operation | work of the ant-proofing agent 5 is performed after driving the earth-concrete 3 and forming the groove | channel 4. FIG. That is, it is possible to drive the soil concrete 3 before the ant-proofing treatment, and there is no problem caused by preceding the ant-proofing treatment. In addition, since it is only necessary to dispose the termite-proofing agent 5 in the groove 4, the groove 4 firmly receives and holds the termite-proofing agent 5, and the termite-proofing agent 5 is not scattered around in the placement operation. The ant-proofing agent 5 can be arranged cleanly and appropriately. There is no such thing that the anti-anticide 5 is scattered around after the placement.
[0019]
In the above-mentioned ant-proof structure, the ant-proof agent 5 is firmly and stably held by the groove 4 formed in the joint portion between the soil concrete 3 and the cloth foundation concrete 1. Intrusion of termites and the like from the underfloor soil 2 can be reliably prevented.
[0020]
In the embodiment shown in FIG. 1 (c), the cross-sectional shape of the groove 4 is made triangular by the vertical surface 6 of the concrete cloth foundation 1 and the slope 7 formed between the concrete soil 3. The termite inhibitor 5 arranged in the groove 4 tries to enter the bottom of the groove 4 along the slope 7, and therefore, the termite inhibitor 5 is surely attached to the joint portion between the foundation 1 and the soil concrete 3. Can be centralized.
[0021]
In the embodiment shown in FIG. 1 (d), a groove 4 for disposing the termite-proofing agent 5 is provided at the joint between the soil concrete 3 and the cloth foundation concrete 1, and another groove 9 is further provided therebelow. The lower groove 9 is filled with an elastic sealing material 10. The elastic sealing material 10 primarily prevents intrusion of termites and the like from the under-floor soil 2, and when the sealing material 10 is broken, the anti-anticide 5 secondarily prevents invasion.
[0022]
2A, 2B, and 2C show still other embodiments. That is, cracks are generated in the soil concrete 3 due to the contracting action of the concrete. The embodiment shown in FIGS. 2 (a), (b), and (c) relates to an ant-proof structure that prevents termites and the like from entering from the underfloor soil 2 through the cracked portion.
[0023]
In the embodiment shown in FIG. 2 (a), a weak strength groove 12 is formed on the upper surface of the concrete soil 3 in advance to cause cracks, that is, to induce cracks. Is arranged filling. The groove 12 is provided with a small groove 12b at the center in the width direction of the groove bottom of the upper cross-sectional square groove 12a, and a crack is generated in advance in the small groove 12b portion. Even if a crack occurs in this portion, the termite-proofing agent 5 exists above the portion, so that termites and the like can be reliably prevented from entering from the underfloor soil 2 through the crack portion.
[0024]
In the embodiment shown in FIG. 2 (c), the elastic sealing material 10 is filled in the small groove 12 b in the above-mentioned poor strength groove 12, and the granular anti-bacterial agent 5 is filled in the upper cross-sectional square groove 12 a. is there. The elastic sealing material 10 primarily prevents intrusion of termites and the like from the underfloor soil 2 through the cracked portion, and when the sealing material 10 is cut, the anti-anticide 5 secondarily prevents invasion.
[0025]
In the embodiment shown in FIG. 2B, the small groove 12b is omitted. Since the granular termite-proofing agent 5 is filled and disposed in the groove 12, the termite-proofing agent 5 can prevent the intrusion of termites and the like from the cracked portion regardless of which part in the groove 12 is cracked. .
[0026]
Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, a case where a granular material is used as the termite-proofing agent is shown, but in addition to the powdery termite-proofing agent and the jelly-like termite-proofing agent, solid, fluid, semi-fluid Various forms of termite-proofing agents such as shapes may be used. In short, it may be any anti-anticide suitable for holding in the groove. Further, the groove includes a groove having a poor strength, and the cross-sectional shape thereof is not particularly limited, and may be formed in a groove having various cross-sectional shapes. Moreover, in said embodiment, although the concrete cloth foundation is illustrated as a foundation, it is not restricted to this, For example, a steel foundation may be sufficient and a boulder stone etc. may be sufficient. In short, it may be a structural part that produces a joint in relation to soil concrete. In the above embodiment, the elastic sealing material is shown as an example of the combination with the termite-proofing agent. Good.
