  However, conventionally, a test apparatus for grasping the ant protection performance of the barrier layer for ant protection as described above before construction has not been sufficiently established. In particular, in order to grasp the ant protection performance of the barrier layer for ant protection in a state that is in line with the actual construction situation, a large-scale testing device that reproduces the actual construction site is often used, which requires a lot of labor and cost. Needed.

  Therefore, the present invention can easily and inexpensively grasp the ant-proofing performance of the barrier layer for ant-proofing in order to eliminate the above-mentioned problems and prevent the entry of termites in a state in accordance with the actual construction situation. The purpose is to provide an anti-ant performance test apparatus.

In order to solve the above-mentioned problems, the ant-proof performance testing apparatus according to the present invention is a gap between the inner peripheral surface of the frame body and a termite path above the soil layer filled in the concrete frame body. A concrete layer is provided so as to form a gap, and the barrier layer is interposed between the soil layer and the concrete layer so as to close a lower end portion of the gap, or the gap is formed above the concrete layer . The barrier layer is provided so as to close the upper end portion, and a test body that is damaged by termites is installed on the upper surface of the concrete layer.

  Furthermore, the gap is filled with paper or wood that is damaged by termites.

In another aspect of the present invention, there is provided an apparatus for testing ant-repellent performance, in which a pipe material is vertically inserted into a soil layer filled in a concrete frame, and a test body that is damaged by termites is installed at the upper end of the pipe material. In addition, the barrier layer covers a predetermined height of the outer peripheral surface and / or inner peripheral surface of the pipe material serving as a termite passage.

Further, in the above-mentioned ant protection performance test apparatus, the frame body has an open upper end , and the open upper end is covered with a lid member having a heat insulating function.

  Further, a caulking material containing a termite-proofing agent is interposed in the gap between the upper end surface of the frame and the lid member.

  By using the ant proof performance testing apparatus according to the present invention, by confirming the state of damage of the test body provided in the frame, for example, in an actual construction site, a gap portion of a concrete layer such as dirt concrete under the floor of a building It is possible to easily and inexpensively grasp the ant protection performance of the barrier layer for ant protection constructed corresponding to

  In the ant-proof performance testing apparatus according to another invention, for example, in an actual construction site, the ant-proof performance of the barrier layer for ant-proofing that is constructed corresponding to the insertion point of pipes such as piping under the floor of the building is simple and inexpensive. Can grasp.

  Furthermore, by covering the open upper end of the frame with a lid member having a heat insulating function, it is possible to prevent the temperature inside the frame from rising and the occurrence of dew condensation in the frame due to direct sunlight, and termites are likely to act inside the frame. The environment can facilitate the test. Furthermore, the gap between the upper end surface of the frame body and the lid member is closed with a caulking material containing an anti-bacterial agent, thereby preventing termites from entering the frame from the outside and increasing the reliability of the test results. Can be increased.

  An ant barrier layer (6) is laid between the outer peripheral surface of the raised portion (3) and the inner peripheral surface of the frame (2) so as to surround the raised portion (3) of the soil layer (4). ing. Examples of the ant barrier layer (6) include those in which particles containing chemicals are spread, those in which inorganic particles are spread, and liquid agents spread on the upper surface of the soil layer.

  In addition, a concrete layer (7) assuming interstitial concrete is provided above the raised portion (3) and the barrier layer (6) of the soil layer (4), and bait trees (7) are provided on the upper surface of the concrete layer (7). 8) is installed. Between the inner peripheral surface of the frame (2) and the concrete layer (7), corrugated cardboard (9), which is a paper material that is damaged by termites, is filled. A gap (S) is secured.

  In addition, a cardboard (9) is provided in advance along the inner peripheral surface of the frame (2), and then a concrete (7) is formed by placing concrete and then a gap (S) is naturally secured. To be. Further, the corrugated cardboard (9) is not necessarily provided. For example, instead of the corrugated cardboard (9), wood that is damaged by termites may be filled in the gap (S). Further, a plastic plate or the like may be provided instead of the corrugated cardboard (9), and the gap (S) without a filler may be secured by removing the plastic plate after the concrete layer (7) is applied.

  Moreover, the open upper end part of the frame (2) is covered with a lid member (12) having a heat insulating function in which a heat insulating material (11) is installed on the upper surface of the metal plate (10). This prevents direct sunlight from entering the frame (2) and prevents condensation in the frame (2), making the frame (2) an environment where termites can easily act. Yes. Further, a mass body such as a concrete block (13) is placed on the upper surface of the lid member (12) so as to press the lid member (12). In the gap between the upper end surface of the frame (2) and the metal plate (10) of the lid member (12), a caulking material (14) containing an termite-proofing agent is interposed to prevent termites from entering. ing.

  That is, in this ant protection performance test apparatus (1), by interposing the barrier layer (6) between the soil layer (4) and the concrete layer (7) so as to close the gap (S), Termite passages from the soil layer (4) through the gap (S) to the bait tree (8) are blocked by the barrier layer (6).

It is possible to easily and inexpensively grasp the ant protection performance of the barrier layer for ant protection constructed so as to cover a part of the surface.

(Second Embodiment)
FIG. 3 shows an ant proof performance testing apparatus according to the second embodiment.

  This ant-proofing performance testing device (20) has a frame (2) filled with a soil layer (21) facing the termite-exposed land (5), and a concrete layer above the soil layer (21). (7) is provided, and a bait tree (8) is installed on the upper surface of the concrete layer (7). Between the inner peripheral surface of the frame (2) and the concrete layer (7), corrugated cardboard (9), which is a paper material that is damaged by termites, is filled. A gap (S) is secured.

  And a barrier layer (22) is provided on the upper side of the concrete layer (7) so as to close the gap (S), and reaches the bait tree (8) from the soil layer (4) through the gap (S). Termite passages are blocked by a barrier layer (22). Other configurations are the same as those of the ant-proof performance testing apparatus according to the first embodiment.

  By using the ant-proof performance testing device (1) constructed in this way, for example, in the actual construction site, the soil is corresponding to the place where the foundation rises under the floor of the building and the soil concrete contacts. The ant protection performance of the barrier layer for ant protection constructed so as to cover a part of the concrete can be grasped easily and inexpensively.
