Description

[Detailed description of the invention] The present invention relates to a shear wall.

It takes a lot of effort and hard work to use this construction method.
Cheap.

There is a practical limit to the magnitude of the prestress due to constraints on the casing 2f'li.

It is impossible to lower the center of gravity by 1 degree when the prestress is applied to -.

The purpose of the invention is to provide a first-order L-elseismic system that is made for points such as T and K at the top.

Earthquake-resistant clothing that can carry large loads.

<ff> Earthquake resistance that can lower the center of load to a lower potential.Next, the solid line -IK will be explained.

Kui〉 Endurance III#j! Configuration (1) is a core wall that serves perpendicularly to the reef ring, and the main wall of the elevator room, the main wall of the main bud of the duct, and the main wall of the first staircase can be used.

Direction K of blasting the space inside = A II (1) on the ceiling (2) of the space surrounded by this = 11 (1) or on an appropriate floor
[L*Horizontal material K, hanging # t3) Noue 4 t' FIA
“ii! Do it.

Using steel such as RIH steel as the hanging material (3),
Then, weights (4) are scattered on the bottom 4 of this hanging material (3). This weight (4) is movably located in the bottom chamber (5) at the lower end of the core tube (tl) at a constant distance from the surrounding area of the bottom chamber (5) and the bottom plate (6). .

As the weight (4), a material with a high specific gravity such as a lump of scrap iron is used.

The core tube (
1) It will be constructed as a ii1 rectangular and same direction trace from above.

In addition to ordinary pills, the amulet structure (1) can also include tower-like structures such as cement silos, tanks, and chimneys.

<Mouth> How to construct a resistant back wall ■ Since a build-up building naturally wins from the bottom, there is no way to hang the weights (4) with the hanging materials (3) from the beginning.

Weight 14 from the top after ms to Kagami Ill
) It is difficult to lift a heavy weight (4) because there is a lot of distance from the top of the cutting board.

Therefore, in the construction method of the present invention, the bottom 1 (5) of the Ilk bottom of the core wall (1) is filled with a fluid (7) for temporary support, and granules such as liquid medium sand.

Then, a weight (41? is buried with the upper part exposed and a hanging material 13 fixed to the weight (4)) is placed inside this fluid (7). Extending upward, the ceiling of core 1 (1) W5+21,
Or, at the same time, place one horizontal piece of material at an appropriate position (3 pieces of hanging material)
) harden the top end? do.

■ Removal of fluid In that situation, motorized body (7) t @ t! 16) If removed from the inside, weight (4) is the bottom'! (5) It will be suspended in the space inside.

The best way to remove the fluid (7) is to discharge it from the outlet (8) at the bottom of the bottom 1 (5)! With this method, not only liquids but also particles such as sand can be flushed out together with water.

・By using the 4 knobs, it is also possible to turn the material into waves and discharge the constant material upward.

After discharging the fluid (7), a liquid or the like is used as a resistor to suppress the free movement of the weight (4) to a certain degree.
Fill in i (6).

If the temporary tlIt moving body (7) and the resistor are made of the same material, they may be able to be used as is.

Characteristics of the shear wall of the present invention The shear resistance stress of the present invention m1ii: τ, stress C, stress degree of the surface perpendicular to the crack in the concrete 4. .

, then.

It can be seen that in the equation for e t 6 41 @ 8r-7 #, σ19 y 0 is significantly reduced due to the presence of σC.

σ, o1. . If =O, then the spring constant of the core is, and the displacement is X, then Q*! , so the stressed compressive force N of the wall is.

N=2Q-2Kx where Nwcao, K=acna, so) fz
(6n.

In other words, it tries to remain stationary.

By utilizing this unique property, the role of the vector can be freely determined and modes can be created.

In other words, it is sufficient to keep it in a stationary state and install a hanging base at point t^.

The difference from -et stress concrete is that heavy objects are present, and the overall center of gravity is lowered, causing l
1lf becomes small and falls over and runs over.

The characteristic period T is 9 long and does not cause coexistence with external forces.

The conventional tower-shaped m- (@3 figure) and the present invention's flat shape (@4@
When comparing l) and t ratios, the difference in state is obvious. In addition, in each figure, 1 is the 1st time when reciting, and is the brj mode.

Figure 5 shows the relationship between t% poverty and stress.
The difference between (A) and the conventional *(8) becomes clear.

Since the swage-resistant construction method of the present invention will last for a long time, the following effects can be expected.

〈A〉 - There are 4 big words in the work, so it is recommended when ponding.Moreover, 16 is apparently at the lowest position, so it is very stable.

Since the core I11 is compressed and stressed through the hanging material by constructing a heavy object, the stress 1 in the core tube can be reduced.

〈/-〉 Since the heavy 11vtJ carries out the shore excursion of the hanging cone, the + and l existence of the lanterns decreases, and the displacement between the @ of Shima Rui is extremely small compared to the general seismic temperature. Ru.

0 Efforts have been made to make the main pipe have a large yield strength.
The strength of the i's beak can be reduced and the weight can be saved.

(g) Since the bottom chamber is filled with fluid, it is possible to attenuate the inertial movement of the weight when it is moved, and it also acts as an initial resistance for horizontal erection, effectively suppressing vibrations.

<To> The size of the weight, the viscosity of the surrounding fluid, the position of the hanging material, etc. have been significantly adjusted to reduce the noise that AD must pay attention to.
Lol! It can be used as a highly adaptable earthquake-resistant pipe.

<G> Compared to the method of applying pre-stress by embedding tensile material into the buds, this method is extremely simple to construct, does not require special equipment or equipment, and requires no maintenance.

〈C〉 The elevator space is surrounded by hanging materials and elevator #i! , IIl + piping, etc., so no wasted space is created.
