Abstract

PURPOSE:To prevent the separation of elastic materials by a method in which one of buried plates is connected to one beam steel frame, the other is inserted between two holding plates fixed to the other beam steel frame, and a visco- elastic material set between the plates is restrained. CONSTITUTION:Plates 2a and 2b are each vertically set in the upper and lower ends of a concrete board 1 projectionally, and the board 1 is set between beam steel frames 3a and 3b. The plate 2a is fixed to the frame 3a and fixed with cement mortar 6, The plate 2b is set in parallel with the flange of the frame 3b and inserted between two holding plates 7 attached with a visco-elastic material 4. The plate 2b is bonded to the plates 7 in a horizontally movable condition, and the plates 7 are restrained from both sides by the mortar 6. The separation of the elastic material 4 can thus be prevented.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention has the ability to absorb energy during earthquakes, etc.
It concerns the emplacement wall.

[Problem that the invention seeks to solve]

In order to suppress the shaking of high-rise buildings during earthquakes and strong winds, various restraining walls have been proposed that absorb the vibration energy by transmitting the vibration of the building to a viscoelastic body and converting it into thermal energy.

The energy absorbing parts of these restraining walls are constructed by sandwiching a viscoelastic body between steel plates and gluing them together, as shown in Figure 3, but in this structure, only one end of the outer plate is restrained with bolts. Because of this, when an out-of-plane force is applied to the restraining wall, there is a risk of peeling at the adhesive surface between the plate and the viscoelastic body.

This invention was made by focusing on the structural weaknesses of such conventional restraining walls, and aims to propose a new stable restraining wall that is free from the risk of peeling.

[Means for solving problems]

In the present invention, the above-mentioned problem is solved by covering the clamping plates that sandwich the viscoelastic body with mortar from both sides and restraining them over the entire length.

For the restraining wall, concrete plates are placed between the steel beams on the upper and lower floors.
By joining one of the embedded plates protruding from the upper and lower ends to one of the beam steel frames, and sandwiching the other plate via a viscoelastic body between two clamping plates fixed in parallel to the other beam steel frame. configured.

The viscoelastic body is bonded between both surfaces of the embedded plate and the clamping plate in such a manner that both sides can move relatively horizontally in the in-plane direction, and the clamping plate is restrained from both sides as described above.

〔Example〕

The present invention will be explained below based on the drawings showing one embodiment.

As shown in Fig. 1, the restraining wall A of this invention has one embedded plate 2a protruding from a concrete plate 1 fixed to a steel beam 3a on either the upper or lower floor, and the other embedded plate 2b It is formed by joining to the other beam steel frame 3b via a viscoelastic body 4.

The embedded plates 2a and 2b are embedded inside the upper and lower ends of the concrete plate 1 and protrude vertically in the in-plane direction, as shown in FIGS. 1 and 2.

Concrete 1 and board 1 are the steel beams 3a of the upper and lower floors.

3b, one of the embedded plates 1-22 is fixed to one of the beam steel frames 3a by bolting or the like to a joining plate 5 joined thereto along the embedded plate 2a. The embedded plate 2a and the joining plate 5 are embedded with mortar 6.

As shown in the figure, the other embedded plate 2b is inserted between two clamping plates 7.7 fixed in parallel to the flanges of the other beam steel frame 3b, and between both sides of this embedded plate 2b and the clamping plates 7.7. A viscoelastic body 4 is bonded to the embedding plate 2b and the clamping plate 7.7, that is, the concrete plate 1 and the beam steel frame 3b are relatively movable horizontally.

The outer side of the wound of the clamping plate 7.7 is filled with mortar 6 as shown in the figure, and the clamping plate 7.7 is restrained in an out-of-plane direction from both sides.

〔Effect of the invention〕

This invention is as described above, and since the clamping plates that sandwich the viscoelastic body are restrained from both sides by mortar, they are stable against out-of-plane directional forces and can prevent the viscoelastic body from peeling off. .
