Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall configuration of a wall strength comparison sensation device for a building. The wall strength comparison sensation device 1 is provided at the lower part of two bases 2 and 2 on the left and right sides, and mounting sections 3 and 3 for mounting two wall bodies A1 and A2 having different structures, respectively.
Pressing means 4, 4 provided on the upper portion of the base 2 for pressing the upper ends of the walls A1, A2 in the width direction to apply horizontal stress from the upper ends of the walls A1, A2; Load detecting means for detecting a load when a horizontal stress is applied from the upper ends of the walls A1, A2 by the pressing means 4, 4, and upper ends of the wall A1, A2 by the pressing means 4, 4. Displacement amount detecting means for detecting the displacement amount of the walls A1 and A2 when a horizontal stress is applied, and the load and displacement amounts detected by the load detecting means and the displacement amount detecting means, respectively. , Load display devices 51 and 52 and displacement amount display devices 61 and 62 as display means.

The strength of the walls is compared based on the wall magnification of the walls A1 and A2. As for the wall magnification, as shown in FIG. 2 (a), the wall body provided with the lath B1 on the frame material B is 0.5, and as shown in FIG. 2 (b), one brace B2 is provided on the frame material B. The number of the walls is 2, and the number of the walls provided with the structural plywood B3 on the frame material B is 2.5 as shown in FIG.
The structural plywood B3 is attached to the frame material B by nailing a plurality of nails at equal intervals.

Accordingly, the wall magnification of the wall A1 is 4.5 for the lath B1 and the two braces B2, and the wall magnification of the wall A2 is 4.5 for the one brace B2 and the structural plywood B3. It becomes 5.

It is to be noted that the wall magnification 1 is based on the condition that the deformation is not more than 1/120 · Lmm when a load of 130 kg is applied.
For 2, the load was 4.5 × 130 kg = 585 kg
, A guideline is that the amount of deformation is L / 120 mm or less.

The mounting portions 3 are for supporting the lower ends of the walls A1 and A2, and firmly fix the lower ends of the walls A1 and A2 which are vertically arranged by bolting 31 or the like. I have. The walls A1 and A2 are arranged with their backs facing forward so that differences in structure can be easily understood.

Each of the pressing means 4 sandwiches both sides of the upper end of the walls A1 and A2, and includes a movable body 41 having sandwiching portions 41a and 41b which are movable in the horizontal direction in the left and right directions. A jack device 42 as driving means for moving the right and left 41 in the horizontal direction is a main part.

The movable body 41 is guided by a guide rail (not shown) so that the holding portions 41a and 41b can move smoothly above the base 2 as described above.
The left and right holding portions 41 a and 41 b are connected by a connecting rod 43.

The jack device 42 has a telescopic part which is configured to be telescopic by a motor (not shown).
The expansion and contraction section is connected via a load cell (not shown) as load detection means.

The amount of expansion and contraction of the jack device 42 or the amount of movement of the movable body 41 is detected by a sensor (displacement amount detecting means) such as a potentiometer, so that the wall A
1. The displacement amount when a horizontal stress is applied by pressing the upper end of A2 in the horizontal direction by each pressing means 4 is detected.

The loads and displacements detected by the load detecting means and the displacement detecting means are input to a control device (not shown), and the load display devices 51 and 52 and the displacement display device 61 are transmitted through the control device. , 62.

The load display devices 51 and 52 are installed on a support 53 provided between the bases 2 and 2, and display units 51a and 52a for displaying loads as numerical values are arranged on the front surface.

The displacement amount display devices 61 and 62 are composed of a plurality of display lamps 61a and 62a arranged in a horizontal line at predetermined intervals, and the wall members A1 and 62a are arranged around the center display lamps 61a and 62a. The display lamps 61a and 62a on the side where A2 is pressed are sequentially turned on as the displacement amount increases. In this embodiment, each time the displacement increases by 5 mm, the display lamps 61a and 62a are sequentially turned on.

Lighting lamps 63, 64 are provided in the upper middle of the displacement amount display devices 61, 62.

Next, using the wall strength comparison sensation device 1 configured as described above, the walls A1, A2 having different structures are used.
The following describes the procedure for giving the visitor a comparative experience by seeing how the intensity of the light is different.

First, a horizontal stress is applied from the upper end of the wall A1. Specifically, the start switch on the wall A1 side is pressed, and the pressing means 4 is operated based on a command signal from the control device, and the upper portion of the wall A1 is slowly pressed from right to left. At this time, the load applied to the wall A1 is displayed on the load display device 51, and the displayed load gradually increases with the operation of the pressing means 4. This makes the wall A
On both side edges of 1, tension and compression occur, and the displacement at that time is displayed by sequentially lighting the left display lamp 61 a from the middle display lamp 61 a of the displacement amount display device 61.

When the displacement reaches 25 mm (the six display lamps 61a are turned on), the lighting lamp 63 is turned on based on a command signal from the control device, and a wall magnification of 4.
5, which is the maximum value which is a reference value of the displacement amount in the case of the wall body A1 having a height of 3000 mm and 25 (3000/120 m
m), the operation of the pressing means 4 is stopped when the amount of displacement has increased to some extent from 25 mm, and the load at this time is displayed on the load display device 51.

Next, the wall A2 is pressed by the pressing means 4 in the same manner as described above. In this case, due to the structural characteristics of the wall A2, even when the displacement of the wall A1 reaches the same load as when the displacement reaches 25 mm, the displacement is smaller than that of the wall A1. The comparison shows the lit display lamp 61
A visitor can easily understand the number of a and 62a.

Then, the operation of the pressing means 4 is continued,
When the load reaches 585 Kg based on the wall magnification 4.5 described above, the pressing means 4 is stopped based on a command signal from the control device, and the amount of displacement in this case is indicated by the number of lighted display lamps 62a.

Thus, the visitor can see the wall A1 and the wall A
2, the wall A1
In contrast, it can be understood at a glance how the wall A2 is structurally superior in strength.

Specifically, as an example of the experimental results of the numerical values of the load and the displacement on the walls A1 and A2, the displacement of the wall A1 is 30 to 35 mm when the load reaches about 400 kg. And 2 at a load of 585 kg
In contrast to the displacement of 5 mm, the displacement of the wall A2 is about 15 mm when the load reaches 585 kg.
Was shown.

Note that the above-described procedure is executed by a program preset by the control device, and this program may be appropriately set so that the visitor can easily compare.

[0029]

As described above, at least two walls having different structures are placed, horizontal stress is applied to the upper end of each wall by the pressing means, and the load and displacement at this time are displayed through the display means. By showing it to the visitor, the visitor can understand at a glance the difference in strength between the walls having different structures. As a result,
This can stimulate the willingness to purchase a building such as a house employing a wall having a structure with excellent strength, and can be a great selling point.
