Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a joint device for covering and shielding a space between two building frames that are placed in close proximity to each other.

[Conventional technology]

Conventionally, joint devices of this type have various structures. For example, JP-A-60-
The joint device disclosed in No. 13155 attaches a cover plate with a spring member that provides a reversal elastic force.

[Problem that the invention seeks to solve]

However, with structures that use conventional spring members like this, if the clearance between the two body parts becomes large to a certain extent, it becomes difficult to manufacture due to constraints on the shape and dimensions of the spring members, so it is necessary to add a lot of reinforcement. , it will have to be extremely large. and,
If the clearance changes significantly during an earthquake, and if both building blocks vibrate more than a certain amount in the internal and external directions, it will not be possible to respond adequately. There was also the problem that providing large clearances and great adaptability would result in extremely high costs. Another problem was that the installation work was difficult. In particular, when the cover plate was pulled outward by wind force (negative pressure), there was a risk that it could not withstand it and come off.

[Means for solving problems]

According to the first invention, a pair of edge members are fixed to the edges of the building blocks facing each other with a predetermined clearance and have longitudinal grooves opening inward; and a gap between the building blocks having the clearance; a cover plate for closing the section from the outside; an engaging protrusion that slidably and swingably engages with the groove of the edge material; and a back surface of the cover plate; In a joint device for a building, the connecting member is inserted into a hole in a cover plate, and a bridging rod is attached to the side via a connecting member so as to be able to swing freely. A bolt that is inserted into the elongated hole; A spacer that is interposed between the cover plate and the bridging rod to prevent both from being smaller than a predetermined size; a spring holder having a rotation stopper plate made of a U-shaped plate material that is held together, a nut part integrated with the rotation stopper plate, and further screwed onto the bolt; An elastic member is provided between the spring holder and the bridging rod to elastically draw the cover plate toward the bridging rod.

Further, according to the second invention, the bridging rod is
a main body in the form of a strip or rod; the above-mentioned engagement protrusion having a hemispherical head attached to both ends thereof; standing up from the outer surface of the main body, in the connected state of the above-mentioned connector; , a leaf spring-like contact piece that curves and elastically contacts the back surface of the cover plate;
Further, the coupling device includes a bolt, a nut portion, and a spacer that is interposed between the cover plate and the bridging rod to prevent both from being smaller than a predetermined size.

[Effect]

On the back side of the cover plate, the engaging protrusions at both ends of the bridging rod slide while engaging with the grooves of the pair of edge members, and the entire bridging rod swings.
Adapts to changes in clearance between both bodies.

In addition, on the back side of the cover plate, the engaging protrusions at both ends of the bridging rod swing while engaging with the grooves of the pair of edge members, and the entire bridging rod swings in the inward and outward directions. Flexibly adapts to changes in the internal and external directions of the body.

Of course, it is possible to simultaneously adapt to the two types of changes between the two bodies, and the amount of adaptation is extremely large.

The cover plate is swingably attached to the bridging rod by a connector and is always held securely despite large changes in the mutual positional relationship of the frame.

Furthermore, according to the first invention, since the spacer is interposed between the cover plate and the bridging rod, it is possible to prevent the cover plate from being deformed by excessively tightening the bolts.

In addition, since the spring holder has a rotation stopper plate made of U-shaped plate material and a nut, even though the structure is compact and simple, when the bolt is rotated from the outside and screws, , it can prevent the nuts on the invisible back side from spinning around.

Next, according to the second invention, the bridging rod is provided with an engaging protrusion having a hemispherical head, and can easily engage with the groove of the edge material, and can be easily engaged with the groove of the frame member in multiple directions. Both ends of the bridging rod tend to follow the displacement.

Furthermore, since it has a leaf spring-like contact piece, during installation work, before and during bolt tightening, the bridging rod is not parallel to the cover plate on the back side and swings excessively, causing the ends of the bridging rod to swing excessively. To prevent a problem in which an engaging protrusion does not smoothly engage with a concave groove of an edge material.

As is clear from FIG. 2, the rotation stopper plate portion 35 made of a U-shaped plate material holds both side edges of the bridging rod with a margin.

As shown in FIG. 4, the bolts 32 are located between the small protrusions 29 during installation work and in a normal state.
If the bolt 32 and the bridging rod 22 move relative to each other during an earthquake or the like, the bolt 32 can move to the left or right in FIG. 4 beyond the small protrusions 29.

Further, as shown in FIG. 2, the length dimension of the bridging rod 22 is set so as to be inclined when viewed from the back surface. In other words, the distance between the engaging protrusions 25 and 25 is set larger than the maximum distance between the grooves 13 and 13 of the edge members 4 and 5 that is expected to occur during an earthquake, etc.
While changing the inclination angle of the bridging rod 22 centering on 0, the distance between the edge members 4 and 5 changes, i.e., the frames 1 and 2.

Easily adapts to any of the changes mentioned above.

Note that the contact pieces 27, 27 are connected to the cover plate 19.
The bridging rod body 22 is kept substantially parallel to prevent it from being extremely tilted. Figures 1 and 2 show the main body 1,
2 shows the case of an external wall. The same structure as shown in the figure can also be used for jointing ceilings. In this case, it goes without saying that the inside-outside direction B corresponds to the up-down direction of the ceiling.

Next, FIG. 6 shows a configuration that is almost the same as that of the above-described embodiment, but the difference is the connector 30. In other words, a leaf spring is used as the resilient member 38 in place of the coil spring shown in FIG. 22 so that the plate spring and the bridging rod body 22 rotate integrally around the axis of the bolt 32.
The holder 37 in the figure is omitted. Other than this, the same reference numerals are the same as in FIG.

Next, in another embodiment shown in FIG. 7, a joint device for covering the space 3 between the roofs from above is shown.
