Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a joint device for closing off the gap between the two building frames of buildings that are juxtaposed side by side.

[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 reversible spring force.

[Problem that the invention attempts to solve]

However, with structures that use such conventional spring members, 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 inward and outward directions beyond a certain level, it will not be possible to respond adequately. There was also the problem that the large clearance and large adaptability would make it extremely expensive. Another problem was that the installation work was difficult. In particular, when the cover plate is pulled outward by wind pressure (negative pressure), there is a risk that the cover plate will not withstand the force and come off.

The object of the present invention is to provide a joint device for buildings that can solve the above-mentioned problems of the conventional art.

[Means for solving problems]

The joint device for buildings of the present invention includes a pair of edge members that are fixed to the edges of opposing building blocks with a predetermined clearance and have longitudinal grooves that open inward; and an interval between the building blocks that has the clearance. a cover plate for closing the section from the outside; engaging protrusions attached to the back side of the cover plate and slidably and swingably engaged with grooves of the edge material; both ends of the engaging protrusions; a bridging rod having; a bolt that is inserted into the cover plate and the bridging rod in a skewer-like manner; a nut member that does not rotate; a first elastic member that is interposed between the cover plate and the bridging rod and elastically separates the cover plate and the bridging rod; and the bridging rod; a second elastic member interposed between the nut member and elastically pulling the bridging rod and the cover plate; and a connector for attaching the cover plate to the edge material via the bridging rod engaged with the bridging rod.

[Effect]

With the above configuration, the engaging protrusions at both ends of the bridging rod slide while engaging with the grooves of the pair of edge members on the back side of the cover plate, and the entire bridging rod swings. This allows it to adapt to changes in the clearance between both bodies.

In addition, 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 in the inward and outward directions. Flexibly adapts to changes in the internal and external directions of both body parts.

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.

Furthermore, since the bridging rod is held in a sandwiched manner by the first elastic member and the second elastic member of the coupling device, the bridging rod does not wobble when the cover plate is attached to the edge material, and the bolts do not move. Rotation can be accurately transmitted to the bridging rod via the nut member.

〔Example〕

Hereinafter, the present invention will be explained in detail based on drawings showing embodiments.

In FIGS. 1 and 2, 1 and 2 are building blocks that face each other with a gap 3 having a predetermined clearance L (body spacing), and in the illustrated example, the building blocks 1 and 2 are

Attach the frame 1 to the anchor bolts 6 with the fixing tools 7...
It is fixed to the outer surfaces of the corners 8 and 9 of the edges 1a and 2a of 2. Furthermore, water stop plate holding pieces 10, 10 are provided on the edge members 4, 5 in a protruding manner extending from the corner portions 8, 9 toward the center of the spacing portion 3, respectively. Further, a groove 11 is formed at the tip of the holding piece 10, into which both ends of a water stop plate 12 made of a thin film of plastic or rubber are fitted.

Furthermore, the edge members 4 and 5 have longitudinal grooves 13 and 13 that open inward, that is, toward the spacer 3 side.
Specifically, the pair of edge members 4 and 5 are cover plates that extend in a direction in which they approach each other and are connected to the base end of the water stop plate holding piece 10 and the inner wall 14. It has a holding piece 15. The groove 13 has a substantially inverted U-shape in cross section, and is formed on the back surface of the cover plate holding piece 15. Also,
The outer wall 16 of the edge materials 4 and 5 has an outer wall mortar layer 17.
It is set to be substantially flush with the outer surface 17a. The cover plate holding piece 15 has
A gasket 18 is fitted into the gasket 18, and a gasket fitting recess 19 is formed in the holding piece 15 in the illustrated example at a position opposite to the inverted U-shaped groove 13.

The numeral 20 is a substantially strip-shaped cover plate having a width sufficiently larger than the clearance L, and is used to cover and shield the gap 3 between the frames 1 and 2 from the outside. Specifically, both ends of the cover plate 20 are bent into a U-shape, and water-tight sealing materials 21, 21 are attached to the tip edges of the cover plate 20.
It comes into close contact with the outer surface 17a. Further, a shallow groove 22 in the longitudinal direction is formed by bending in the center.

Therefore, 23 is a concave groove 1 with edge members 4 and 5 at both ends.
3 and 13 to support the cover plate 20. That is, as shown in FIG. 1 and FIGS. 3 to 5, this bridging rod 23
The main body part 24 is bent into a U-shape in cross section and has a band-like or rod-like shape as a whole, and a hemispherical head part 26 rotatably attached to both ends thereof and has a flange 25. It is comprised of mating protrusions 27, 27 and leaf spring-like contact pieces 28, 28 that stand up from the outer surface of the main body 24.

A long hole 29 is provided in the center of the main body 24 in the longitudinal direction, and as shown in FIG. 4, two small protrusions 30 are formed at the center of each long side of the long hole 29. . As shown in FIG. 1, the hemispherical heads 26 of the engagement protrusions 27 at both ends are movable in the direction of arrow A and slidable in the longitudinal direction. It engages with the groove 13. Further, both ends of the main body portion 24 are formed into a tapered shape. Furthermore, the pair of contact pieces 28, 28 are bent in a direction in which the distal ends thereof approach each other.

31 attaches the cover plate 20 to the edge members 4, 5 via the bridging rod 23 with the engaging protrusions 27, 27 engaged in the grooves 13, 13 of the edge members 4, 5. This is a connector to be installed.

As shown in FIG. 6, this connector 31 includes a bolt 32 that is inserted into the cover plate 20 and the bridging rod 23 in a skewered manner, and is screwed onto the bolt 32 and is inserted from the bridging rod 23. A nut member 33 is provided on one side and does not rotate together with the bolt 32, and the nut member 33 is interposed between the cover plate 20 and the bridging rod 23 and elastically connects the cover plate 20 and the bridging rod 23. a first elastic member 34 that separates the bridging rod 23 and the nut member 33; and a second elastic member that is interposed between the bridging rod 23 and the nut member 33 and elastically pulling the bridging rod 23 and the cover plate 20 together. A generating member 35 is provided.

Specifically, the nut member 33 consists of a rotation stop plate 36 made of a U-shaped member, and a nut 37 integrated with the rotation stop plate 36 by welding. The opening of the bridging rod 23 is set to face the opening. Then, the bolt 32 is screwed into this nut 37. Further, the second resilient member 35 is made of a coil spring in the illustrated example, and is interposed between the rotation stopper plate 36 and the bridging rod body 23. Further, the first elastic member 34 is made of a coil spring similar to the second elastic member 35, and a cylindrical spacer 38 is fitted on the outside to prevent the distance between the cover plate 20 and the bridging rod 23 from being less than a predetermined dimension. has been done.

Therefore, the bolt 32 is inserted into the hole 39 which is inserted through the groove 22 of the cover plate 20 at a predetermined pitch.
, the first resilient member 34 to which the cylindrical spacer 38 is fitted, the elongated hole 29 of the bridging rod body 23, and the second
The resilient member 35 is inserted into the shape of a skewer and screwed onto the nut 37.

Therefore, when the bolts 32 are tightened, the cover plate 20 and the bridging rod 23 are connected to the first resilient member 3.
4, the bridging rod 23 and the cover plate 20 are elastically urged to be pulled together by a second elastic member 35. 4
0 is a sealing washer interposed between the bolt 32 and the cover plate 20.

As shown in FIG. 4, the bolts 32 are located between the small protrusions 30 during installation work and under normal conditions.
If the bolt 32 and the bridging rod 23 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 30.

Further, as shown in FIG. 2, the length dimension of the bridging rod body 23 is set so as to be inclined when viewed from the back surface. In other words, the expected edge materials 4 and 5 during earthquakes, etc.
The distance between the engaging protrusions 27, 27 is set larger than the maximum distance between the grooves 13, 13, and the bridging rod 23 changes its inclination angle around the connector 31, and 4 and 5 - that is, the skeletons 1 and 2 are displaced as shown by arrows M and N, and the clearance L increases and decreases. At this time,
The hemispherical head 26 of the engagement protrusion 27 slides along the grooves 13, 13 of the edge members 4, 5.

Furthermore, when the frames 1 and 2 change relative to each other in opposite directions, as shown by the arrow B, the central part of the bridging rod 23 is formed with an elongated hole 29, and the bridging rod 23 is in the first position. Adaptation is achieved by being pressed by the springing member 34 and the second springing member 35 and movable in the axial direction of the bolt 32, and by the fact that the hemispherical head 26 of the engagement protrusion 27 is swingable. I can do it.

Of course, the cover plate 20 only contacts the edge members 4 and 5 via the gaskets 18 and 18, and also contacts the outer surface 17a of the outer wall mortar layer 17 of the frames 1 and 2 through the seal members 21 and 21. Since it only has the following characteristics, it can easily adapt to any of the changes mentioned above.

Note that the contact pieces 28, 28 are connected to the cover plate 20.
The bridging rod body 23 is kept substantially parallel to prevent excessive inclination. Further, since the contact piece 28 is bent at the tip side, when the cover plate 20 is attached to the edge members 4 and 5, the contact piece 28 is easily bent in a certain direction by tightening the bolt 32. If the tip side of this contact piece 28 is not bent, it is impossible to predict how this contact piece 28 will bend when it is pressed by tightening the bolt 32. This makes it unstable to keep the cover plate 20 and the bridging rod 23 substantially parallel. Further, although FIGS. 1 and 2 show the case where the frames 1 and 2 are external walls, the structure shown in the figures can also be used when a ceiling is joined to a ceiling. In this case, it goes without saying that the inside-outside direction B corresponds to the up-down direction of the ceiling.

Thus, in order to attach the cover plate 20 to the edge members 4 and 5, the bridging rod 23 is attached in advance to the back surface 20a side of the cover plate 20 using the connector 31. In this case, the bolt 32 is tightened to such an extent that the respective resilient members 34 and 35 act slightly.
That is, this bridging rod 23 does not swing around its axis, and the rotation of the bolt 32 is caused by the rotation of the nut member 3.
3 to the extent that it can be accurately transmitted to the bridging rod 23. Further, the inner diameter of the groove 13 is set to be sufficiently larger than the outer diameter of the hemispherical head 26 of the engagement protrusion 27. And cover plate 20
Tighten the bolts 32 from the outside of the bridging rod body 2.
3 and pull the bridging rod 23 further outward, the engagement protrusions 27, 27 of the bridging rod 23 will easily and accurately engage with the grooves 13, 13 of the edge members 4, 5. Thus, the cover plate 20 can be easily attached to the edge members 4 and 5. Note that since both ends of the main body portion 24 of the bridging rod 23 are tapered, it is easier for the protrusion 27 to engage with the groove 13.

However, if the outer diameter of the hemispherical head 26 and the concave groove 13
If the inner diameter of the bridging rod 23 is set to be approximately the same as the inner diameter of the bridging rod 32 and the first elastic member 34 and the second elastic member 35 are not present, the bridging rod body 23 will wobble during installation, and furthermore, the rotation of the bolt 32 will not be the same as the bridging rod 32. The problem arises that the force is not transmitted to the bridging rod body 23 accurately, and furthermore, the engagement protrusions 27, 27 of the bridging rod body 23 do not accurately engage with the grooves 13, 13 of the edge members 4, 5. However, the joint device of the present invention does not suffer from the above-mentioned problems.

Next, FIG. 7 shows a configuration that is almost the same as that of the above-described embodiment, but the difference is the connector 31. That is, a plate spring is used instead of the coil spring for the second resilient member 35 in FIG. 1, and the nut 37 is integrally provided with this plate spring. and,
The tip of this leaf spring is a bridging rod 2 with a U-shaped cross section.
3, so that the leaf spring and the bridging rod body 23 rotate integrally around the axis of the bolt 32. In this case, the nut member 33 is formed only from the nut 37. Other than this, the same reference numerals are the same as in FIG.

Next, another embodiment shown in FIG. 8 exemplifies the case of a joint device that covers the space 3 between floors. In this case, the structure is almost the same as that of the embodiment shown in FIG. 1 described above, but the outer surface of the cover plate 20 has a decorative uneven pattern,
The width of the cover plate 5 is increased compared to the case shown in FIG. 1, and the cover plate 20 is held on the edge members 4 and 5 with a gasket 41 interposed therebetween.
Further, the head of the bolt 32 is of a countersunk screw type so that it does not protrude from the upper surface of the cover plate 20.

The large-width edge members 4 and 5 are each fixed to the frame bodies 1 and 2 near the center with anchor bolts 42, and on the outer ends via another anchor 43. An upper opening groove 45 is formed in the longitudinal direction to accommodate a nut 44 screwed onto the upper end of the former anchor bolt 42, and a π-shaped cover member 46 is attached to the upper opening groove 45 to accommodate a nut 44 screwed onto the upper end of the former anchor bolt 42. is formed into a continuous flat surface in the middle except for the left and right edges. That is, a concave groove 19 is formed at the edge on the side of the spacer 3 and the gasket 18 is fitted therein to support the lower surface of the cover plate 20, and the outer edge of the gasket 41 is formed at the opposite edge. A concave groove 47 into which the holder is fitted is formed by two protrusions. The inner edge of the gasket 41 is locked to the back surface of the cover plate 20, and when the cover plate 20 moves in the width dimension with respect to the edge members 4 and 5, it moves together with the width dimension, so that the width of the gasket 41 changes. The dimensions are expandable and deformable. This gasket 41 has an upper wall and a lower wall folded into a bellows shape to expand and contract in the width dimension, and a vertical wall connecting the upper wall and lower wall vertically in parallel at a predetermined pitch so as to withstand external force from above. have

Next, in another embodiment shown in FIG. 9, a joint device for covering the space 3 between the roofs from above is shown.

Angle members 48 are provided on the edges 1a, 2a of the frames 1, 2 that face each other with a predetermined clearance L, and a pair of edge members 4, 5 are attached with screws 49 through the angle members 48.
to fix. The cross-sectional shape of the edge members 4 and 5 is a stepped shape that slopes downward toward the outside. A cover material 50 made of a stainless steel plate is fixed to the side surfaces of the edge materials 4 and 5. Similar to the previous embodiment, the edge members 4 and 5 are provided with grooves 13 that open inward.

The cover plate 20 has a roof-shaped cross section that is high at the center and slopes downward to the left and right sides. The back surface 20a (lower surface) of the cover plate 20 is
Both end edges 20 of the cover plate 20 are slidably supported by the edge members 4 and 5 via the edges 8 and 18.
For b and 20b, a sufficiently large left and right margin as shown by dimension C is set. Reference numerals 51 and 51 designate packing materials that are attached to both end edges 20b and 20b of the cover plate 20 and are brought into close contact with the outer surface of the exterior.

Therefore, the connector 31 in this case does not include the cylindrical spacer 38, and is configured to follow the vertical displacement of the cover plate 20. In other words, the cover plate 20 in this case
are formed to be inclined downward to the left and right sides, so if the clearance L increases or decreases, the contact area between the packing 18 and the cover plate 20 moves, and the cover plate 20 changes vertically. However, the bridging rod 23 in this case can be vertically displaced by the first resilient member 34 and the second resilient member 35, and can follow the vertical displacement of the cover plate 20. Note that the same reference numerals as in FIG. 1 are the same as in FIG. 1, so the explanation will be omitted.

Next, the modification shown in FIG. 10 shows a joint device for connecting the outer walls with each other as an inner corner. This is completely the same as FIG. 1 except for the difference, and the explanation thereof will be omitted.

10, the rotation stopper 36, spacer 38, and second resilient member 35 in FIG. 1 are omitted, and a nut 37 is screwed onto the bolt 32. The bridging rod 23 is rotatable around the axis of the bolt 32.

By the way, the left half of the figure will be explained below.The left edge of the cover plate 20 is bent upward and further to the right, and in consideration of rain protection, the left edge is bent with a hinge 52 or the like as indicated by the arrow G. The other end edge 20b is pivotally attached so as to be vertically swingable.

Specifically, the edge material 4 on the side of the frame 1 has a concave groove 53 that opens to the right in the figure, a lower piece 54, a mounting piece 55 that abuts the outer surface 17a of the outer wall mortar layer 17 of the frame 1, It is formed by the upper piece portion 56. A screw receiving groove 57 is formed in this upper piece 56, and one end of the hinge 52 is fixed to this with a screw 58. Further, a groove opening upward is formed at the tip of the lower piece portion 54, and a sealing material 59 is fitted into the groove, and the sealing material 59 is brought into elastic contact with the lower surface of the cover plate 20.

A water stop plate holding piece 10 having a groove 11 at the lower end for attaching the water stop plate 12 is vertically provided from the lower piece portion 54 along the outer surface 60 of the frame 1. Further, a fitting groove 61 that can be elastically opened and closed slightly is formed in the upper piece portion 56 at a position above the screw receiving groove 57 for the screw.
Attach the fixing tool 63 to the cover plate 62 with screws 64,
The insertion piece of the fixing tool 63 is press-fitted into the fitting groove 61 to fix the covering plate 62 to the edge material 4. A sealing material 65 is attached to the lower edge of this covering plate 62,
It comes into close contact with the upper surface of the cover plate 20. In this way, the hinge 52, screw 58, etc. are covered with the cover plate 62 to prevent rainwater from entering. Also, 66 indicates a patchkin.

67 is a substantially L-shaped reinforcing member interposed between the cover plate 20 and the bridging rod 23 on the left side in the figure, in place of the contact piece 28. Also,
The thickness dimension T of this reinforcing member 67 is determined by the contact piece 28.
This reinforcing member 67 is set larger than the thickness dimension t of The length L is the length L between the cover plate 20 and the bridging rod 23 in the installed state without the reinforcing member 67 interposed therein.
Set it slightly larger. Therefore, bridging rod 2
The protrusion 27 of No. 3 easily engages with the groove 13 of the edge member 5, and moreover, engages firmly and reliably.

Then, when the main body 1 and the main body 2 are positioned relative to each other as shown by arrow B, the cover plate 20 swings around the axis of the hinge 52, and the concave groove 1 of the edge material 5
While the engaging protrusion 27 swings as shown by arrow A,
Adapts to the above positional deviation (vibration, etc.).

In addition, as shown by arrows M and N, in the case of positional deviation (vibration, etc.) that increases or decreases the clearance L,
The bridging rod body 23 swings around the axis of the bolt 32,
In addition, the engaging protrusion 27 is adapted to slide in the longitudinal direction of the concave groove 13 of the edge member 5.

[Effect of idea]

In the joint device of the present invention, the bridging rod 23 is attached to the back surface 20a side of the cover plate 20 in advance by a connecting tool 31, and the bridging rod 23 is attached by operating the connecting tool 31 from the outer surface of the cover plate 20. When rotated and further pulled outward, the engagement protrusions 27, 27 of the bridging rod 23 are fitted into the grooves 13, 13 of the edge members 4, 5, and are engaged and installed. It is easy to install.
Further, in a state where the bridging rod 23 is attached in advance to the back surface 20a side of the cover plate 20 by the connecting tool 31, the bridging rod 23 is connected to the first resilient member 34 and the second resilient member 35 of the connecting tool 31. Since the bridging rod 23 is held in a pinched manner by the bridging rods 23, the bridging rod 23 does not wobble, and the rotation of the bolt 32 can be accurately transmitted to the bridging rod 23 via the nut member 33. Therefore, even if the clearance L is different in size, the engaging protrusions 27, 27 can be accurately and easily engaged with the grooves 13, 13.

Furthermore, since the bridging rod body 23 in the form of a strip or a rod is used, the joint device becomes particularly suitable when the clearance L is large. That is, the bridging rod 23 having a simple shape and structure can bridge between the bodies 1 and 2 having a sufficiently large clearance L while maintaining sufficient strength and rigidity. In particular, even when the cover plate 20 is strongly pulled by wind pressure (burden), the bridging rod 23 can sufficiently withstand it.

Of course, large adaptations can also be made in fluctuations in which the clearances L of bodies 1 and 2 increase or decrease relative to each other as shown by arrows M and N, fluctuations in the direction shown by arrow B, and even in combinations of these. Be flexible in terms of quantity.

This joint device is designed to simplify the structure and reduce the weight, especially for the frames 1 and 2 having a large clearance L.
