Conduct various environmental tests such as durability, watertightness, earthquake resistance, durability, solar radiation resistance, rainfall resistance, etc. in a fixed state or by changing the relative position of the test equipment and the test house by rotating the table. This article relates to a residential environmental testing device that has made it possible.

[Conventional technology]

2. Description of the Related Art Conventionally, various environmental tests on houses, etc. are often conducted with the house, etc. in a fixed state, using different testing devices for each test item.

An example of an apparatus for testing the wind resistance and rain resistance of houses and the like is disclosed in Japanese Patent Publication No. 53-34912.

In other words, a horizontal duct is installed under the ceiling of the room to which air is supplied by an appropriate blower, and the upper end opening can be connected to the required connection port of the horizontal duct as appropriate, and each side has a removable shutter plate that can be opened and closed. This type of duct has a vertical duct with air exhaust ports arranged in multiple stages.

A water sprinkling nozzle is provided at the exhaust port of the vertical duct, and the wind or rain is blown by air from a blower.

Here, the horizontal duct has a number of connection ports opened and closed on the bottom surface, each of which is opened and closed by a shutter plate, and by connecting the upper end opening of the vertical duct to these connection ports as appropriate, the test object can be connected to the test object. The location of the blowing wind or wind and rain can be selected horizontally.

Furthermore, by opening and closing the exhaust port of the vertical duct with a shutter, the position of the wind or wind and rain blowing on the test object can be selected in the vertical direction.

In addition, since the house vibration test was conducted by fixing the test house on the table of a vibration generator specifically designed for vibration tests, it was difficult to perform other strong wind and water spray tests from multiple directions. If various tests were to be performed from multiple directions, the testing equipment would either be moved around the house, or a table fixed to the house together with a vibration generator would be rotated.

[Problem to be solved by the invention]

In the above-mentioned device, it is necessary to select the connection port of the horizontal duct, install the upper end opening of the vertical duct, and close it with shutters of other connection ports, and change the position from which the wind or rain is blown. In some cases, there was a problem that the work was complicated.

In addition, the positions at which wind and rain are blown can only be selected from the number of connecting ports provided in the horizontal duct, making it difficult to conduct detailed tests.

For this reason, it is conceivable to provide a large number of connection ports, but this would complicate the work of closing the shutter and also pose a risk of air leakage.

In view of these problems, the present invention installs a turntable on the floor of an environmental test chamber, provides a test house on the turntable, and installs various environmental test devices in the test chamber. In addition to making it possible to perform each test with the house in a fixed position or displacing it by rotation, when conducting a vibration test, the rotation axis of the turntable is released to apply lateral vibration to the turntable. The purpose of this project is to provide an environmental testing device for residential use.

[Means to solve the problem]

In order to achieve the above object, the present invention installs a turntable on the floor of an environmental test chamber, which is rotatable around a rotating shaft placed in the center and has an air lift device attached to its lower surface. The rotating shaft can be removed or released from the turntable in response to vertical movement by a lift device,
With the rotating shaft removed or set free, transverse vibrations are applied to the test house installed on the turntable in conjunction with the push and pull action of a seismic test cylinder detachably installed on the side of the turntable. In addition to making seismic tests possible, it is also possible to install various test devices in the test room and perform various tests by changing the relative position of the test house and the test device by rotating the turntable. A residential environmental test device was constructed.

In addition, various test devices such as a local water leak test device, a strong wind, water spray device, and a duct with a built-in fan for wind pressure tests are installed outside the test house installed on the turntable.

Also, a turntable connected in a divisible manner can be used.

Furthermore, as an air lift device, a support is provided below the center of the lower surface of the base, and a torus bag is provided around the support on the lower peripheral surface of the base.
bag), and on one side of the base,
It is possible to use a device equipped with an air supply body that supplies pressurized air to the inside of the torus bag and the space under the base surrounded by the torus bag.

[Effect]

When changing the positional relationship and angle of the residential environmental test device according to the present invention with various test devices installed around the test house, the turntable is slightly suspended using an air lift device, and the rotation axis is adjusted. The test is carried out by rotating the turntable around the center, and in order to perform the vibration test, the turntable is rotated to a predetermined position as described above, and the rotating shaft is removed or released in response to the vertical movement by the air lift device. A cylinder for seismic testing is attached to the side of the turntable, and in conjunction with the push/pull motion of the cylinder, lateral vibration is applied to the test house installed on the turntable. By making the test cylinder removable, it is possible to set the direction of lateral vibration applied by the cylinder to multiple directions of the test house.

When the turntables are connected so that they can be divided, the size and shape of the turntables are changed as appropriate depending on the size of the test house.
