Description of the Related Art Conventionally, an outer wall panel made of lightweight cellular concrete containing bubbles is used on the outer wall of a residential building in order to enhance heat insulation and the like. Examples of the outer wall panel include a so-called closed cell in which bubbles are independent, and a so-called open cell in which bubbles are continuous with micro capillaries. Differences in these exterior panels were introduced in residential building catalogs and verbally explained to prospective buyers who visited the exhibition hall.
[0003]
[Problems to be solved by the invention]
However, the outer wall panels actually used for the outer walls of residential buildings are almost the same in appearance, so it is easy to introduce their performance, such as differences in strength, etc. in the catalog or explain verbally. It is difficult to understand and takes time to explain and becomes annoying.
[0004]
Furthermore, in the case of introductions in catalogs and verbal explanations, the difference in strength is simply grasped by numerical values, which causes the inconvenience that the difference in strength of each outer wall panel cannot be impressed. It will be.
[0005]
The present invention has been made in view of such a point, and the object of the present invention is to easily grasp the difference in strength between different types of outer wall panels and to provide an impression of the strength difference. To provide a comparative experience device.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 shows an outline of the overall configuration of the external wall panel strength comparison experience device 1, and FIG. 2 illustrates the usage state of the same strength comparison experience device 1.
[0013]
That is, the external wall panel strength comparison experience device 1 includes an exhibition room 2, a test piece mounting portion 3, a harken 4, and a lever 5, as shown in FIGS.
[0014]
The exhibition room 2 includes a plate 21 that has a substantially rectangular shape in plan view, and a transparent protective cover 22 that covers the upper side of the plate 21. The plate 21 is installed on the upper surface of the pedestal 12 installed on the floor surface 11 shown in FIG. 2, and is positioned near the adult's crotch height. Further, the protective cover 22 is formed in a substantially semicircular cross section with a reinforced plastic material such as polycarbonate, for example. The protective cover 22 is attached to the approximate center of the plate 21 and opens at both ends in the longitudinal direction of the plate 21. As a result, the exhibition room 2 is designed so that an adult can look inside through the protective cover 22 from above.
[0015]
A test piece mounting portion 3 is provided inside the exhibition room 2. The test piece mounting portion 3 includes a pair of test piece mounting frames 31 and 31 laid in parallel with each other over the longitudinal direction of the plate 21. Between the test piece mounting frames 31 and 31, two first and second test pieces 32 and 33 made of different types of outer wall panels are mounted at a predetermined interval in the longitudinal direction of the plate 21. As each of the test pieces 32 and 33, both are formed by forming an outer wall panel made of lightweight cellular concrete containing bubbles inside into a rectangular parallelepiped block shape. As the first test piece 32 (on the left side in FIG. 1), one in which bubbles are continuous with micro capillaries is used. Further, as the second test piece 33 (the right side in FIG. 1), one in which bubbles are independent is used. The test pieces 32 and 33 are displayed side by side in the longitudinal direction of the plate 21 when viewed from the near side in the lateral direction of the plate 21 (left side in FIG. 2).
[0016]
The Harken 4 is individually arranged so that it can be applied to each of the test pieces 32 and 33 individually. Each Harken 4 is located in the middle of each support shaft 42 extending orthogonally to the rotation shaft 41 on the back side in the exhibition room 2, that is, the back side in the short direction of the plate 21 (right side in FIG. 2). Is provided. Each rotary shaft 41 is rotatably installed between the upper end portions of a pair of rotary shaft support members 43, 43 erected on the back side in the lateral direction of the plate 21. Each Harken 4 is rotated in the vertical direction along a trajectory A (shown in FIG. 2) having the rotation shaft 41 as a fulcrum, and is individually struck against each of the test pieces 32 and 33 when rotated downward. It is done.
[0017]
Further, stopper pieces 44 (only one is shown in FIG. 2) are erected on the plate 21 positioned between each test piece mounting frame 31 and each rotation support member 43. Each stopper piece 44 restricts the downward rotation of the harken 4 by contacting the support shaft 42 when the test pieces 32 and 33 are crushed by the harken 4 and further rotated downward. Like to do. The tip of each spindle 42 protrudes outside the exhibition room 2 through slits 22 a and 22 a that open in the protective cover 22. Each of the slits 22a is formed by cutting out the protective cover 22 in accordance with the direction of rotation of each Harken 4, that is, the locus A direction.
[0018]
The lever 5 is attached to the distal end portion of the support shaft 42 that protrudes outside the exhibition room 2 through the slits 22a so as to be orthogonal to the rotation shaft 41, respectively.
[0019]
Next, a method for using the outer wall panel strength comparison experience device 1 will be described with reference to FIGS.
[0020]
First, as shown in FIG. 1, in use, a first test of open cells is performed at a predetermined position (a position spaced apart in the longitudinal direction of the plate 21) between the test piece mounting frames 31 and 31 of the test piece mounting portion 3. The piece 32 and the second test piece 33 of closed cells are respectively mounted through the openings at both ends of the protective cover 22.
[0021]
Next, the hands of the experience person (not shown) experience by comparing the strengths of the first and second test pieces 32 and 33 in order.
[0022]
That is, one lever 5 (for example, the left lever 5 corresponding to the first test piece 32) is rotated upward to a position indicated by a virtual line (two-dot chain line) in FIG. At this time, the lever 5 is positioned at a height near the shoulder of an adult.
[0023]
Then, the one lever 5 is rotated downward to the solid line position shown in FIG. 1 and FIG. 2 with the hands of the experience person himself, and the Harken 4 is hit on the upper surface of the first test piece 32.
[0024]
At this time, in the open-cell first test piece 32, the upper surface of the first test piece 32 is likely to be dented by the strike of Harken 4, and can be experienced to be crushed in some cases.
[0025]
On the other hand, like the one lever 5 described above, the other lever 5 (for example, the right lever 5 corresponding to the second test piece 33) is rotated upward, and the other lever 5 is moved downward by the hands of the experience person. Is rotated to the upper surface of the second test piece 33.
[0026]
At this time, the closed-cell second test piece 33 is less likely to be dented due to the strike of the Harken 4 on its upper surface, and it can be experienced that the Haken 4 strikes the same degree as the first test piece 32.
[0027]
Accordingly, it becomes possible to compare the strengths of the test pieces 32 and 33 by individually hitting the Harken 4 against the first test piece 32 and the second test piece 33, respectively. The difference in strength between the pieces 32 and 33, that is, the two different types of outer wall panels, becomes clear. Thereby, the difference in strength of these outer wall panels can be easily grasped, and the difference in strength can be impressed.
[0028]
Further, since it is possible to predict to some extent the moment when the lever 5 is rotated downward, that is, how much force is applied, the Harken 4 is struck against the test pieces 32 and 33. , 33, the strength of the test pieces 32, 33 can be realized.
[0029]
In addition, depending on the difference between the test pieces 32 and 33, the test pieces 32 may be recessed or not recessed with the same driving force, so that the difference in strength between the types of the test pieces 32 and 33 can be realized.
[0030]
Further, when the test pieces 32 and 33 are hit by the Harken 4, the test pieces 32 and 33 are covered with the transparent protective cover 22, so that the pieces of the test pieces 32 and 33 are scattered outside the display room 2. There is nothing, and the strength comparison experience of each test piece 32, 33 can be performed safely.
[0031]
In addition, the strength comparison experience device 1 of the outer wall panel is installed in the housing exhibition hall, and the strength of the outer wall panel is varied depending on the type of the outer wall panel by having the person who visits the housing exhibition experience. You can get to know if they are different.
[0032]
In the present embodiment, it is possible to experience the strength comparison between the two first and second test pieces 32 and 33 made of different types of outer wall panels, but three or more test pieces made of different types of outer wall panels. An intensity comparison experience device that can experience the intensity comparison of may be configured. In this case, for example, in addition to the first test piece in which the bubbles are continuous and the second test piece in which the bubbles are independent, the strength is compared with a third test piece in which the bubbles are partially partially continuous. Can also experience.
[0033]
In this embodiment, the first and second test pieces 32 and 33 are mounted between the test piece mounting frames 31 and 31, but the test pieces can move in the plate longitudinal direction with respect to the test piece mounting frames. Each test piece is moved in the longitudinal direction of the plate each time the hammer is struck, so that the tester can easily hit the test piece at a new location. Of course, it is possible to do so.
[0034]
Furthermore, in this embodiment, each test piece 32, 33 is provided with a corresponding harken, but each test piece is movably placed on the plate, and each test piece is alternately placed on the harken strike site. By positioning, it is possible to experience the strength comparison of each specimen (outer wall panel) with a single Harken.
[0035]
【The invention's effect】
As described above, according to the strength comparison experience device of the outer wall panel in the present invention, by experiencing the strength comparison of each test piece by striking Harken individually against a plurality of test pieces made of different types of outer wall panels, The strength difference between these outer wall panels can be clarified, the strength of each outer wall panel can be easily grasped, and the strength difference can be impressed.
[0036]
Further, the strength of each test piece can be realized by predicting the Harken's hitting force to each test piece to some extent by applying the force at the time of lever operation, and checking the degree of depression of the hitting portion of each test piece. In addition, the presence or absence of a dent due to the difference in the test piece occurs depending on the force applied when operating the lever, and the difference in strength for each type of test piece can be felt.
[0037]
Furthermore, since each test piece is covered with a transparent protective cover, it is possible to safely perform a strength comparison experience without splashing the pieces of each test piece outside the exhibition room when each test piece is struck by Harken. .
