Description

[Detailed description of the invention] [Field of industrial application] The present invention aims to investigate the performance of building side walls in order to obtain data on wind pressure resistance, water tightness, earthquake resistance, etc. More specifically, in order to test the performance of such a side wall of a building, a support member is protruded outward from the upper end of a polygonal main frame having at least one corner, and This invention relates to a performance testing device for the side wall of a building, which has columns suspended downward and horizontal slabs attached to the columns.

[Conventional technology]

As an apparatus for performing performance tests on curtain walls and other building side walls, there is one disclosed in Japanese Utility Model Publication No. 47489/1989.

That is, as shown in FIG. 5, a variable frame body b for mounting a test object is attached to a rectangular main frame a so that it can be twisted and bent by means of pins.

C is a pressure chamber equipped with a pressure blower and a water spray nozzle, and is fixed to the floor.

Further, a wheel d is provided at the lower part of the main frame a, and is movable on a rail e on the floor surface.

Here, the side wall of the building, which is the test object, is attached to the variable frame b.
The seismic test is carried out by attaching the variable frame b to a hydraulic jack and vibrating it using a hydraulic jack.

In addition, the main frame a is moved close to the pressure chamber c to perform wind pressure resistance tests, water tightness tests, and the like.

[The problem that the idea attempts to solve]

The above-described building side wall performance testing device is only intended to vibrate the variable frame b in one direction, and is capable of performing interlayer displacement tests within the mounting surface of the test object. However, it is impossible to conduct vibration resistance tests such as vibration in a direction perpendicular to the mounting surface of the test object, vibration in a 45° direction, and other seismic performance tests.

In addition, the variable frame b has an L-shape in plan view, and even if a side wall including one corner can be tested, a side wall including multiple corners, for example, a side wall having a substantially U-shape in plan view, may be tested. cannot be tested against.

Furthermore, in order to bring the test object closer to the pressure chamber c and perform wind pressure tests, water tightness tests, etc., it is necessary to move the main frame a, and during this movement, the test object is subjected to vibrations, twisting, and other forces. In addition, there is a problem that performance tests lack accuracy.

In addition, although the test object is attached to the front surface of the variable frame b, it may be attached in a state where it protrudes forward from the main frame a, and the test object may fall forward because the main frame a is not fixed. There is a risk.

Furthermore, since the main frame a to which the test object is attached is moved, a heavy-load foundation is required along the entire length of the rail e.

The present invention aims to provide a performance testing device for building side walls that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, a support member is provided to protrude outward from the upper end of a fixed polygonal main frame having at least one corner, a column is suspended downward from the support member, and a column is attached to the column. This constitutes a performance testing device for building side walls with horizontal slabs attached.

[Effect]

The present invention has the above-mentioned configuration, and a test object such as a side wall of a building is attached to the slab, and by applying vibration to the column or slab, a seismic performance test is performed by applying interstory displacement to each slab. In addition, wind pressure tests, water tightness tests, etc. are conducted by bringing a pressure chamber equipped with a pressure blower, water nozzle, etc. close to the chamber.

〔Example〕

To further explain the details of the present invention based on the illustrated embodiments, Fig. 1 is an explanatory perspective view illustrating the technical concept of the present invention, and Figs. 2 and 3 show the performance of the building side wall according to the present invention. FIG. 1 shows a plan view and a side view of an example in which a test device is specifically implemented.

Now, the details of the present invention will be further explained based on these figures. What is shown as 1 in the figures is a polygonal main body frame having at least one corner, for example, a right angle, and in the embodiment, it is a flat frame. A rectangular main frame is used. The main frame 1 is constructed of steel or the like so as to have the height and strength as a performance testing device for the side wall of a building.

Here, having at least one corner, for example, a right angle, in the main body frame 1 means that the main frame 1 has at least one corner, for example, a right corner, in order to measure wind pressure resistance, water tightness, earthquake resistance, etc. near the corner where two side surfaces intersect, which will be described later. At least one corner is utilized as shown in FIG.
Therefore, even in polygons larger than squares, at least 1
The condition requires that it have two corners.

Reference numeral 2 denotes a support member protruding outward from the upper end of the main frame 1, particularly from the upper end around the one corner, and this support member has a column 3 hanging downward. There is.

In the embodiment, a support member 2 is provided protruding from each corner of the main frame 1, and a pillar 3 is provided hanging downward from the support member 2. Although it is convenient for use to install the support member 3 so that it protrudes from each corner of the main frame 1, it is not limited to the corners, but it is also possible to install the support member 3 from the upper end to the side between the corners. There is no problem in providing a protruding support member or providing a supporting member in a protruding manner over the entire area between the corners.

Next, an appropriate number of slabs 4 to which a side wall of a building to be tested, which will be described later, is attached are installed horizontally on the pillars 3 which are hung vertically from the support member 2. As shown in FIG. 3, the slab 4 is connected by a pin structure to the front and back sides of the pillar 3 which is vertically installed on the support member 2, and is located at the same position so as to sandwich the pillar 3. The test object 5, which is a side wall of a building, is appropriately mounted on the surface of this slab 4.

The upper end of the pillar 3 is pinned 7 to a mounting piece 6 installed below the upper support member 2 using a universal joint or the like, as shown in FIG. They are connected by pins 8 using a universal joint or the like.

Further, the lower end of the column 3 is guided by a rail so as to swing in the direction in which the seismic test is performed, and this rail is made replaceable depending on the direction in which the test is performed.

Of course, it is also possible to omit the rail and leave the lower end of the column 3 free, and there is no particular limitation.

From this, when the pillar 3 moves, the upper and lower slabs 4 are moved in parallel by the pins 8.

The slab 4 is provided along the outer surface of the main frame 1, and for example, the slab 4 is provided along the outer surface of the main frame 1.
one exterior surface, two exterior surfaces including one corner, or two
It can be provided along three outer surfaces including four corners.

The slab 4 whose plan view is shown in FIG. 2 is provided along two outer surfaces including one corner of the main frame 1, and a slab 4a provided along the side surface of the main frame 1; It is connected at an angle of 90° to a slab 4b provided along the front surface of the main frame 1, and is configured to have an L-shape in plan view.

The test object is attached to the outer surface of this slab 4, and a vibration performance test, a wind pressure test, a watertightness test, etc. are performed.

For example, although not shown here, a seismic performance test is performed by attaching a hydraulic cylinder or other pressurized vibration means to the lower end of the column 3 or the slab 4 located at the lowest layer and applying force in the direction of the test. be.

If vibration is applied in the left-right direction (vertical direction in FIG. 2) within the test object mounting surface of the slab 4b located on the front side of the main frame 1, the slab 4a located on the side surface of the main frame 1 will become 4b. It vibrates integrally in a direction perpendicular to the mounting surface of the test object.

Therefore, the pin joint 7 between the column 3 and the mounting piece 6, the pin joint 8 between the column 3 and the slab 4, the rail at the lower end of the column 3, etc. are connected in the left-right direction (second It must be installed so that it can vibrate in the vertical direction (in the figure), and consideration must be given to the vibration direction of the test. However, if universal joints are used as pins 7 and 8, consideration should be given to the direction in which the pins are installed. is not necessary.

Next, a box-shaped member provided at a certain interval from each slab 4 is a test object 5 attached to each slab 4.
The pressure chambers 9 are used to apply pressure for wind resistance and water tightness tests to the air pressure, and as can be seen from FIGS. It is arranged so that it can move back and forth to approach each slab 4.

As can be seen from the plan view in FIG. 2, each pressure chamber 9 can be brought close to the slab 4 which is L-shaped in plan view and is disposed along the two outer surfaces of the main frame 1. It is configured in an L-shape in plan view corresponding to the mounting surface of the test object.

A pressure blower 13 or a suction blower 14 is connected to a pressure blower 13 or a suction blower 14 by an accumulator 12 between each pressure chamber 9, so that a constant air pressure can be applied.

The setting of the slab 4 shown in the embodiment of FIG. 2 is an L-shaped slab in plan view with respect to the main frame 1, but the entire periphery of the main frame 1 or a part thereof, for example, a U-shape in plan view, is shown. Use in the form does not depart from the embodiments of the invention in any way.

Thus, the building side wall performance testing device according to the present invention has a pillar 3 suspended from a support member 2 protruding outward from the upper end of the main frame 1, a slab 4 attached to the pillar 3, and a slab 4 attached to the pillar 3. One or more outer surfaces of the slab 4 are used as test object mounting surfaces, and building wall materials, which are the test object 5, are attached to each surface of the slab, for example, on two surfaces including one corner, and the pressure chamber 9 is A wind pressure test, a water tightness test, etc. are conducted in close proximity to the test object 5.

At this time, when the slab 4 is formed into an L-shape or a U-shape in a plan view, the pressure chamber 9 is correspondingly formed into an L-shape or a C-shape in a plan view.

When there are a plurality of pressure chambers 9, each pressure chamber 9 is connected by an accumulator 12, and then a pressurizing blower 13 is connected through the accumulator 12.
In this experiment, wind pressure is applied from the wind to the wind.

The installation work for attaching the test object 5 to the slab 4 may be done from the front side of the slab, but the main frame 1 is configured as a reaction frame structure, and the installation work is done from the inside of the slab using a scaffold or stairs provided inside the main frame 1. The test object 5 can be mounted from a suitable scaffold or the like provided on the outside of the slab, and then a test device for measuring these can be set up from the main frame 1 side.

As for seismic performance testing, various tests are possible depending on the mounting direction of the vibration means such as a hydraulic cylinder.

For example, as shown in FIG. 4A, the slab 4 is formed into a substantially L-shape in plan view, and a vibration test can be performed in a direction perpendicular to the mounting surface of the test object located on the front surface of the main frame 1.

Further, as shown in FIG. 4B, the slab 4 is configured to have a U-shape in plan view, and a vibration test in a direction perpendicular to the mounting surface of the test object located on the front surface of the main frame 1 can be performed.

In Fig. 4C, the slab located at the front of the main frame 1 and the slab located at the side surface of the main frame 1 are made to vibrate independently, and each is vibrated in the left-right direction within the mounting surface of the test object. hand,
This is to perform side wall performance tests.

Furthermore, in the same way as in the case of FIG. 4C, FIG.
A slab located on the side surface of the main frame 1 is provided so as to be able to vibrate independently, one side vibrates in the left-right direction within the mounting surface of the test object, and the other swings in a direction perpendicular to the mounting surface of the test object. It vibrates.

[Effect of idea]

As described above, the building side wall performance testing device according to the present invention includes a supporting member protruding outward from the upper end of a polygonal main frame having at least one corner,
Since the column is suspended downward from the support member and the horizontal slab is attached to the column, the slab is attached to the column that is suspended from the support member protruding from the upper end of the main frame. Attachment and removal can be easily done from above using a crane, etc., and it is also possible to observe the test specimen from the back side, so there is no need to install an observation stand as in the past, and the main frame can also be used as this observation stand. Moreover, an internal workbench or the like can be attached to the main frame.

Furthermore, if the main body frame has various structures, for example, a lattice structure, the main body will not be deflected and instruments can be attached from the main body, which will improve workability. Since it can be installed from the front, it is easy to change the height of the slab, and the position of the slab can be changed freely depending on the size of the various test specimens.

In addition, since the mounting shape of the slab according to the present invention, that is, the mounting shape of the test specimen and the direction of seismic load can be set as shown in Figure 4, according to various test specimens, It is possible to set the test specimen in a U-shape or in a U-shape, and various configurations can be adopted compared to conventional test equipment.

In addition, since the main frame to which the test object is attached is fixed, no extra force is applied to the test object and there is no twisting or bending.
This enables highly accurate measurements.

Furthermore, even when a heavy side wall or the like is installed as a test object, there is no risk of it tilting or falling down, making it possible to provide a highly safe performance testing device for building side walls.
