Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a joint device for covering and shielding the gap between two parts of buildings that are juxtaposed side by side.

[Conventional technology]

Conventionally, joint devices of this type have various structures. For example, a joint device disclosed in Japanese Patent Application Laid-open No. 13155/1980 attaches a cover plate using a spring member that provides a reversing elastic force.

[Problem that the invention seeks to solve]

However, with structures that use such conventional spring members, if the clearance between the two parts becomes large to a certain extent, it becomes difficult to manufacture due to the shape and dimensional constraints of the spring members, and a large amount of reinforcement is required. Or it will have to be extremely large. Moreover, the clearance changes greatly during an earthquake, and both! ■If the bodies are photographed more than a certain degree in the internal and external directions, it will not be possible to respond adequately. There was also the problem that providing large clearance and great 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.

[Means for solving problems]

The joint device according to 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 a cover plate for closing from the outside.

A bridge having engaging protrusions on both ends that slidably and swingably engage with the concave groove of the edge material, and attached to the back side of the cover plate via a connector so as to be swingable. It is composed of rods and;

[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, causing both! Adapts to changes in clearance between the oral bodies.

Further, 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,
By swinging the entire bridging rod in the inward and outward directions, both! Flexibly adapts to changes in the internal and external directions of the mouth body.

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

The cover plate is attached to the bridging rod by a connecting member so as to be swingable, and is always reliably held despite large changes in the mutual positional relationship of the frame.

〔Example〕

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

In Figures 1 and 2, 1.2 is the predetermined clearance L.
They face each other with a gap 3 of (framework spacing)! In the illustrated example, the frame 1 and the two bodies 2 are outer walls, and edge members 4.5 made of metal shapes are fixed to the edges 1a and 2a of each frame 1.2. be done. Specifically, the anchor bolts 6 are fixed to the outer surfaces of the corners 8° 9 of the edges 1a and 2a of the frame 1.2 using fixing tools 7, and this edge material 4.5 is Water stop plate holding pieces 10.10 are provided extending from the corner portions 8.9 toward the center of the spacing portion 3, respectively. A concave groove 11 is formed at the tip of this holding piece 10, and a water supply plate 1 made of thin film-like plastic or rubber material is formed in this groove.
Both ends of 2 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.

This groove 13 has a semi-elliptical cross section, and is formed on the back surface of the cover plate holding piece 15 which is connected to the base end of the water stop plate holding piece 10 and the inner wall 14. Ru.

The holding pieces 15.15 of the pair of edge members 4.5 extend in a direction protruding from each other. The outer walls 16 of the edge members 4 and 5 are set to be substantially flush with the outer surface of the outer wall mortar layer. A gasket 17 is fitted into the cover plate holding piece 15, and a gasket fitting recess 18 for this purpose is formed in the semi-elliptic groove 1 in the holding piece 15 in the illustrated example.
It is formed in a position that is the front and back sides of 3.

It is composed of.

A long hole 28 is provided in the center of the main body portion 23 in the longitudinal direction. As shown in FIG.
Individual small protrusions 29, 29 are formed. As shown in FIG. 1, the hemispherical heads 26 of the engagement protrusions 25 at both ends are movable in the direction of arrow A and slidable in the longitudinal direction, and are fitted into the grooves 13 of the edge members 4 and 5. engage.

30 is a connector for attaching the bridging rod 22 to the back surface 19a side of the cover plate 19 so as to be able to swing freely.

This connector 30 includes a bolt 32 that is inserted into a hole 31 formed through the groove 21 of the cover plate 19 at a predetermined pitch and also inserted into a long hole 28 of the bridging rod 22; a sealing waffle 33 interposed between the cover plate 19; and a cylindrical spacer 34 interposed between the cover plate 19 and the bridging rod 22 to prevent the distance therebetween from being less than a predetermined dimension. a spring holder 37 which has a rotation stopper plate 35 made of a U-shaped plate and has a nand part 36 welded and integrated therewith and is screwed onto the bolt 32; It is composed of a resilient member 38 such as a coil spring that is fitted onto the outside and interposed between the holder 37 and the bridging rod 22 to elastically draw the bridging rod 22 and the cover plate 19 together. Ru.

As shown in FIG. 4, the bolt 32 is 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, passing over the small protrusions 29.

Further, as shown in FIG. 2, the length dimension of the bridging rod 22 is as follows.
Set it so that it is sloped when viewed from the back side.

In other words, the concave groove 13°1 of the edge materials 4 and 5 that is expected to occur during an earthquake, etc.
The distance between the engaging protrusions 25 and 25 is set larger than the maximum distance between the connecting rods 25 and 25, and the bridging rod 2 is

Furthermore, when the frames 1 and 2 are displaced relative to each other in opposite directions, as shown by the arrow B, the central portion of the bridging rod 22 is formed with: (i) an elongated hole 28; The bridging rod body 22 can move in the axial direction of the bolt 32 while being pressed, and furthermore, it can freely swing due to the engagement between the zero-arc shaped concave groove 13 and the engagement protrusion 25 of the hemispherical head. It is possible to adapt through the configuration and operation of ■■■.

Of course, the cover plate 19 includes the edge material 4.5 and the packing 17.
．． 17, and the frame 1
, 2 are in contact with the outer surfaces of the mortar only through the sealing material 20, 20, so that it can easily adapt to any of the above-mentioned changes.

Note that the contact pieces 27.27 keep the cover plate 19 and the bridging rod 22 substantially parallel to each other and prevent them from being extremely tilted. 1 and 2 show the case where the frames 1 and 2 are outer walls. 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 instead of the coil spring shown in FIG. The first plate spring is fitted into the main body part 23 so that the leaf 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.

Opposing with a predetermined clearance L! (2) Angle members 39 are provided on the edges 1a and 2a of the body 1.degree. 2, and a pair of edge members 4 and 5 are fixed via screws 40. The cross-sectional shape of the edge members 4 and 5 is different from that of the previous embodiment, and has a stepped shape downwardly toward the outside. Then, a stainless steel temporary cover material 41 is fixed to the outer side surface of this edge material 4.5. Similar to the previous embodiment, a recess 113 opening inward is formed in the edge member 4.5.

The cover plate 19 has a roof-shaped cross section that is high at the center and slopes downward toward the left and right sides. The back surface 19a (lower surface) of the cover plate 19 is slidably supported by the edge material 4.5 via the packing 17.17, and the cover plate 1
Both end edges 19b, 19b of 9 are set with a sufficiently large left and right margin as shown by dimension C.

The shape and structure of the bridging rod 22 and the shape and structure of the connector 30 are the same as in the case of FIG. 1 described above, so their explanation will be omitted.

Next, another embodiment shown in FIG. 8 illustrates the case of a joint device that covers the gap 3 between floors. Edges 1a and 2 of the frame 1.2 facing each other with a predetermined clearance L
a longitudinal groove 1 fixed to a and opening inward;
a pair of edge members 4°5 having the clearance L; a cover plate 19 for covering the gap portion 3 of the bodies 1 and 2 from the outside; The above concavity 11
3.13 is provided with engagement protrusions 25.25 on both ends that engage in a slidable and swingable manner, and is attached to the back surface 19a side of the cover plate 19 via a connector 30 so as to be swingable. The cover plate 19 has a decorative concavo-convex pattern on its outer surface, and the width of the edge material 4.5 is the same as in the previously described embodiment. 1, the cover plate 1 is placed on this edge material 4.5 with a gasket 42 interposed therebetween.
9 is held in a placed position. 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 19.

The large-width edge members 4 and 5 are each fixed to the ten bodies 1 and 2 near the center with anchor bolts 43, and on the outer ends via another anchor 44. former anchor bolt 4
An upper opening concave groove 46 is formed in the longitudinal direction to accommodate a nut 45 screwed onto the upper end of 3, and a π-shaped cover member 47 is formed in this
are attached, and the upper surfaces of the edge members 4 and 5 are formed into a continuous flat surface in the middle except for the left and right edges. In other words, a concave 'a18 is formed on the edge on the side of the spacer 3, and the packing 1 is
7 is fitted to support the lower surface of the cover plate 19, and on the opposite edge, a groove 48 into which the outer edge of the gasket 42 is fitted is formed by two protrusions. The inner edge of the gasket 42 is engaged with the back surface of the cover plate 19, and when the cover plate 19 moves in the width direction relative to the edge member 4.5,
The width of the gasket 42 can be expanded and contracted. This gasket 42 has an upper wall and a lower wall folded into a bellows shape to expand and contract in the width direction, and vertical walls 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 a modification shown in FIG. 9, a joint device is shown in which the frame 1 is a wall and the frame 2 is a roof, and as is clear from comparison with FIG. 7, the connecting tool 30 is different. Other than that, the right half of FIG. 9 indicated by the arrow E-E has exactly the same configuration as FIG. 7, so the explanation thereof will be omitted.

Therefore, the spring holder 37 and the elastic member 38 in FIG. 7 are omitted from the connector 30 in FIG. 9, and the Nand portion 3
6 is screwed onto the bolt 32 to hold the cover plate 19 and the bridging rod 22 at a constant distance corresponding to the length of the spacer 34. It can be rotated freely.

By the way, the left half of the figure corresponding to the one-port body 1 side of the wall will be explained below.The left edge of the cover plate 19 is bent upward and further to the right. The other end edge portion 19b is pivotally attached by a hinge 49 or the like so that the other end edge portion 19b can swing vertically as shown by arrow G.

Specifically, the edge material 4 on the side of the frame 1, which is a wall, has a concave groove 50 that opens in six directions in the figure, and a lower piece 51 and an outer surface 5 of the frame 1.
2 and an upper piece 54. The screw receiver forms a groove 57 in this upper piece 54, and one end of the hinge 49 is fixed to this groove with a screw 55. Further, a groove opening upward is formed at the tip of the lower piece portion 51, and a sealing material 56 is fitted into the groove, and the sealing material 56 is brought into elastic contact with the lower surface of the cover plate 19.

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 along the outer surface 52 from the lower piece part 51. Further, in the upper piece 54, a screw receiver for the screw 55 is provided in a fitting groove 58 which can be elastically slightly opened and closed at a position above the groove 57.
form. Attach the fixing tool 60 to the covering plate 59 with screws 61, and insert the insertion piece of the fixing tool 50 into the above-mentioned case. A58 is press-fitted to fix the cover plate 59 to the edge material 4.

62 is caulking. A sealing material 63 is attached to the lower edge of the cover plate 59 and tightly contacts the upper surface of the cover plate 19. In this way, the hinge 49, screw 55, etc. are covered with the cover plate 59 to prevent rainwater from entering. Also 6
4 indicates Patsukin.

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 19 is placed around the axis of the hinge 49.
The groove 13 of the edge member 5 and the engaging protrusion 25 swing as shown by arrow A to accommodate the positional shift (vibration, etc.).

Further, 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 22 swings around the axis of the bolt 32, and the engagement protrusion 25 adapts while sliding in the longitudinal direction of the concave groove 13 of the edge material 5.

Finally, the modified example shown in Fig. 1O is a case where the outer walls are connected as inside corners, and the area on the right side from the arrow H-H is completely the same as Fig. 1 except for the connector 30, so the explanation thereof will be omitted. Although omitted, this connector 30 has the same structure as that shown in FIG. 9. Further, the left half of FIG. 10 has almost the same structure as FIG. 9, so detailed explanation will be omitted, but the shape of the water stop plate holding piece 10 and the opening direction of the groove 11 are different, and
Since there is no caulking, the sealing performance of the packing 64 is important.

The mutual operations of the various parts in response to the movement of the two main bodies 1.2 in the directions of the arrows B and B and the increase and decrease of the clearance L are the same as in the case of FIG. 9.

〔Effect of the invention〕

The joint device of the present invention configured as described above is easy to install, and the bridging rod 22 is attached in advance to the back surface 19a side of the cover plate 19 using the connector 30, and the outer surface of the cover plate 19 is When the connecting member 30 is operated to rotate the bridging rod 22 and pull it further outward, the engagement protrusion 25.25 of the bridging rod 22 will engage the concave groove 13 of the edge member 4.5. .13 and is engaged and installed.

In addition, since the rod-shaped bridging rod body 22 is used, the joint device becomes particularly suitable when the clearance L is large. That is, the bridging rod body 22 having a simple shape and structure can bridge between the mallet bodies 1 and 2 having a sufficiently large clearance L. In particular, even when the cover plate 19 is strongly pulled by wind pressure (negative pressure), the bridging rod 22
is tolerable enough.

Of course, when the frame 1.2 changes its clearance L to increase or decrease as shown by arrows M and N, when it changes in the direction shown by arrow B, and when these changes occur in combination, a large amount of adaptation occurs. Respond flexibly.

In particular, 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.
