Description

The present invention relates to an expansion joint for an outer wall of a seismic isolation building, and in particular, the present invention relates to an expansion joint for an outer wall of a building having a relatively large movable amount between opposing buildings and a relatively large clearance (gap). In the construction of the outer wall, it provides an expansion joint for the outer wall that has excellent design and good workability.

An expansion joint for construction is a dividing line provided to divide the transmission of stress generated by fluctuation factors such as external force applied to a building, and prevents a clash between left and right buildings built adjacent to each other. It is a joint member that closes the clearance C (gap) provided to the wall with a decorative cover that can move following the shaking movement of the building, and connects the left and right buildings so that they can be used together.

  Therefore, expansion joints have different names depending on their mounting members, such as for outer walls, for floors, for ceilings, for roofs, and for inner walls, and their shapes differ depending on the mounting site, In summary, it is composed of an aggregate that moves following a change in the clearance C (gap) due to an earthquake or the like, a decorative edge member attached to the aggregate, and a decorative cover.

  Buildings with seismic isolation structure have a structure in which laminated rubber isolators provided at the bottom of the building absorb seismic energy in the event of an earthquake to ensure the safety of the building and are installed in the building with the seismic isolation structure When the expansion joint is moved in the direction of the azimuth, the direction of the expansion and contraction of the clearance is X in the horizontal direction with respect to the ground, the shear direction with respect to the clearance in the horizontal direction with respect to the ground, that is, the longitudinal direction. The displacement is indicated by Y, and the displacement generated in the vertical direction, such as non-uniform subsidence, and the displacement in the vertical direction with respect to the ground is indicated by Z.

Thus, regarding the expansion joint for the outer wall of the base-isolated building according to the present invention, the above-mentioned aggregate that moves following the change of the clearance C (gap) due to the earthquake or the like, and the decorative edge attached to the aggregate The decorative cover is movable in the X direction, the Y direction, and the Z direction, respectively. Particularly, the movable amount is required to be large in the X direction and the Y direction.

  Therefore, in the conventional expansion joint for outer wall, a flat decorative cover plate is prepared with respect to the clearance C (gap) between the opposed outer wall surfaces, and the clearance C is provided in the decorative cover plate. The shape of the decorative cover plate is generally covered from the outside of the building, and the decorative cover plate is fixed to one wall surface by a hinge-shaped fixing spring, and the other is slidable with respect to the wall surface in the X direction. Many have a structure that can move in the Y direction and the Z direction.

  Thus, the conventional outer wall expansion joint is installed with the decorative cover plate protruding greatly on the opposite outer wall surface, and the expansion joint is usually made of metal such as aluminum or stainless steel. There was a case where a decorative cover plate material made of a clever metal projection appeared on the outer wall of a building by tiling or stone pasting and ruined the design of the building.

  10 and 11 are perspective cross-sectional explanatory views for explaining a conventional example showing the shape of a conventional outer wall expansion joint, and FIG. 10 shows the outer wall surfaces of opposing buildings A and B through a clearance C. FIG. 11 shows a type in which the outer wall surfaces of opposing buildings A and B form an outer wall corner via a clearance C. FIG.

  10 and 11, a clearance C is provided between buildings A and B facing each other, and an expansion joint 50 or 55 having a shape covering the clearance C is provided.

Thus, the movable direction of the expansion joint in FIGS. 10 and 1 is expressed in the direction of the azimuth, the direction of expansion and contraction of the clearance C in the horizontal direction with respect to the ground is X, and the direction in the horizontal direction with respect to the ground. The displacement in the shear direction, that is, the longitudinal direction with respect to the clearance is indicated by Y, and the displacement that occurs in the vertical direction such as uneven settlement is indicated by Z, and the displacement in the vertical direction with respect to the ground is indicated by Z.

  In FIG. 10, the expansion joint 50 includes a decorative cover plate 51 provided between the clearances C between the buildings A and B, and frame members 52 and 53 for attaching the decorative cover plate 51.

The decorative cover plate 51 covers and closes the clearance C provided between the buildings A and B, and is fixedly held by a hinge-shaped fixing spring 54 on the frame member 52 side, and the other is a wall surface. The buildings A and B follow the X, Y, and Z directions, that is, the change and movement of the clearance C when the buildings A swing back and forth, right and left, and up and down in FIG. It is installed so that it can.

  Therefore, if the clearance C is increased as in the case of the seismic isolation joint, the width of the decorative cover plate 51 serving as a closing material is increased.

  Next, FIG. 11 shows an expansion joint 55 at a so-called outer wall corner portion, and the structure of the decorative cover plate 56 of the expansion joint 55 is the X of the clearance C on the side that comes into contact with the outer wall A perpendicularly. , The L-shaped decorative cover plate 56 is fixed on the outer wall A side via a hinge-shaped fixing spring 57, and accordingly the outer wall B side. The decorative cover plate 56 has a large clearance cover portion, and the decorative cover plate 56 has a very large width.

  In recent years, however, the size and height of buildings have increased, and many buildings with seismic isolation structures have been built, so the clearance C between buildings has been about 50mm to 300mm. From 800mm to 1600mm, expansion joints for base-isolated buildings that can follow the movable amount of ± 800mm have been widely used for temporary deformation such as earthquakes.

  Of course, the expansion joint for outer walls with large clearance C covers the clearance C between outer walls with a decorative cover plate made of metal such as stainless steel or aluminum. The weight of the plate material becomes heavier, the safety structure that securely holds the heavy weight decorative cover plate material, and the temporary deformation such as earthquake can move the decorative cover plate material smoothly to follow the shaking, building There has been a demand for the realization of an expansion joint having a movable mechanism that does not damage the expansion joint.

  Further, when the expansion joint for an outer wall having a large clearance C and a large movable amount is manufactured with the configuration of the conventional expansion joint for an outer wall described in FIGS. 10 and 11, the width of the decorative cover plate material is very large. Since the product becomes large and heavy, it is difficult to perform the installation work at a high place.

  In addition, the construction of vertical strip-shaped expansion joints that protrude from other outer wall surfaces with wide metal materials on the outer wall of tiles or stone is significantly impeded by the design of the building. Therefore, it is desired to realize an expansion joint having an appearance that is superior in design.

  According to the present invention, the size and height of the building and the number of seismic isolation structures have been built, so that the clearance C between the buildings has increased from 800 mm to 1600 mm, and temporary deformation such as earthquakes has occurred. Then, we can provide expansion joints for outer walls that can cope with the fact that expansion joints for seismic isolation buildings that can follow the movable amount of ± 800mm have come to be used.

  In addition, the present invention has a clearance C between the outer walls including a decorative cover plate made of an aluminum extruded shape and a continuous scissor made of an aluminum extruded shape compared to a conventional expansion joint for an outer wall having a large clearance C. Because of the structure covered with the hinge-type combination, the weight of the decorative cover plate is naturally reduced, and the weight reduction promotes a safety structure that securely holds the decorative cover plate material, such as earthquakes. Providing a mechanism that can smoothly move the decorative cover plate material even for temporary deformation and follow the amount of movement, and provide an expansion joint for the outer wall with a movable mechanism that does not damage the building and the expansion joint You can also.

  Furthermore, the present invention is applied to an expansion joint for an outer wall having a large clearance C and a large movable amount. However, the present invention relates to an expansion joint for an outer wall having a bellows shape and a stretchable decorative cover plate. By adopting it as a decorative material (finishing material), the construction site was lifted in a contracted shape within the clearance C between the narrow buildings A and B, and the decorative cover plate was adjusted to the clearance C at the mounting position. By extending to the width, the decorative cover plate is installed in the clearance C, and this configuration facilitates the installation work at a high place.

  And the construction of a conventional expansion joint with a shape that protrudes from the other outer wall surface with a wide metal material is applied to the exterior wall of the tile or made of stone, which significantly impairs the design of the building However, in the expansion joint for an outer wall, the present invention sets the back of the decorative cover plate on the inner side of the outer wall that faces the outer wall surface between the buildings A and B. Thus, it is possible to provide an expansion joint for an outer wall having excellent design characteristics and good workability.

  The problem to be solved by the present invention is to provide an expansion joint for an outer wall that is particularly constructed on the outer wall of a base-isolated building and has excellent design and workability.

  In mounting the decorative cover plate of the expansion joint for the outer wall on the clearance C between the buildings A and B, the present invention creates a groove that forms a groove in the outer wall surface between the buildings A and B, or faces each other. There is no structure that is set back on the inner side of the outer wall, and the conventional expansion joint for the outer wall is provided with a decorative cover plate protruding from the front of the outer wall of the building, which significantly deteriorates the overall design of the building. The point was solved.

Further, in the present invention, the decorative cover plate of the expansion joint for the outer wall that is set and backed on the inner side of the opposing outer wall has an expandable bellows shape, and the space between the buildings A and B is When lifting and installing in the gap of the clearance C to be set, the width of the decorative cover plate is reduced by folding the bellows-shaped decorative cover plate at the bellows portion, and the clearance C between the buildings A and B When installing at the construction site, the bellows portion of the decorative cover plate is extended to match the width of the clearance C, so that the installation work can be facilitated.
