Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an expansion joint device between adjacent building frames.

(Prior art) In general, in order to prevent rainwater from flowing down from the space between buildings that are placed side by side with a distance of about 50 mm to 100 mm, a raised frame such as a parapet is installed at the top of the building. It is necessary to provide an expansion joint device in between.

As such an expansion joint device, one shown in FIG. 5, for example, is known. This allows one side end of the cover material 65 to be locked and held by the holding member 60 provided on the wall body a', and
The other end is placed on the support member 1 of the rising frame a, and in this expansion joint device F, the holding member 60 has a locking groove 61 that opens downward at the upper end of the fixed edge 60a. The protruding edge 60b is bent into a hook shape, and a water stop plate fitting groove 60c is formed at the lower end, and a locking uneven strip 62 is formed inside the opening end of the locking groove 61. It is formed. The holding member 60 has a fixed edge 60
A is fixed by screwing it to the wall body a', and an exterior material 63 and a caulking seal material 64 are provided above the projecting edge 60b. Cover material 6
5 has a hanging edge 65b formed at one end of a standing edge 65a, and a locking edge 65c at the other end, and a holding member 6 is provided at the upper end of the locking edge 65c.
A locking jaw portion 66 is formed to lock onto the locking groove 62 of the locking groove 61 of No. 0. A portion of the upright edge 65a on the side of the hanging edge 65b is placed on an airtight material 6 fitted to the support member 1 of the upright frame a.

However, in this case, the cover member 65 is pulled up from the bottom and the locking jaw 66 of the locking edge 65c is inserted into the locking groove 61.
Moving the cover member 65 upward against the load is not only very troublesome, but also may cause the cover member 65 to separate from the support member 1 due to strong winds or the like. The drawback is that it comes off easily.

On the other hand, what is shown in Utility Model Application Publication No. 19409/1983 similarly forms the horizontal edge and the upright edge in an L-shape between two adjacent building frames where one side is a standing frame and the other is a wall frame. A cover material is formed by forming a cover material, and a pair of upper and lower locking portions are formed upward on the wall frame side, and a downward locking portion corresponding to the above-mentioned locking portions is formed on the back side of the upright edge of the cover material. The above-mentioned locking portions are locked together while pressing the cover material downward parallel to the wall frame surface.

In this case, the locking condition is good, but when the cover material is pressed downward parallel to the wall structure surface, the bottom surface of the horizontal edge rises and hits the top surface of the wall structure, making it impossible to press it down any further. Can not. For this reason, the locking operation must be performed by applying a large force while correctly controlling the posture of the cover material, which is still a very troublesome operation.

(Object of the Invention) In view of the above-mentioned drawbacks, the present invention provides an expansion that can be reliably constructed on a building frame with simple work, especially when one of the adjacent building frames is a standing frame and the other is a wall frame.・The purpose is to provide a joint device.

(Means for achieving the object) In order to achieve the above object, the expansion joint device according to the first invention includes a supporting member erected on the rising frame of one of the buildings, and
A holding member is fixed to the wall frame of the other building adjacent to this rising frame, a short joint holder is installed on the supporting member and the holding member via a spring member, and the frame is attached to both ends of the joint holder. In addition to locking the cover material covering the gap, one side of the cover material is held on the holding member of the wall frame, and the other side of the cover material is movably supported on the support member of the rising frame. It is characterized by

Further, in the expansion joint device according to the second invention, the supporting member is erected on the rising frame of one building, and the holding member is fixed to the wall frame of the other building adjacent to the rising frame. ,
The lower surface of one end side of a short joint holder is abutted and supported on the support member by a spring member provided on the joint holder, and the other end of the joint holder is a locking ridge formed on the holding member. At the same time, the supporting member side portion of the cover material covering the space between the building bodies is locked to the one end of the joint holder, and the holding member side of the cover material is locked to the holding member. It is characterized by the fact that

(Example) Examples of the first invention and the second invention will be described below with reference to the drawings.

First, FIGS. 1 and 2 show an expansion joint device according to the first invention,
Symbols A and A' are buildings built in close proximity, and a
is a rising frame such as a parapet wall erected at the top of building A, and a' is a wall frame of building A'. There is an expansion between the rising frame a and the wall frame a′.
A joint device B is attached and covers the space 〓α between the two main bodies a and a'.

The expansion joint device B attaches a spring member 5 to a support member 1 erected at the top end of a rising frame a and a holding member 2 fixed to a wall frame a′. A short joint holder 3 is installed on the support member 1 and the holding member 2 through the joint holder 3, and a cover material 4 covering the space between the skeletons a and a' is secured to the joint holder 3. One side of the cover material 4 is held by the holding member 2 of the wall frame a', and the other side of the cover material 4 is movably supported on the support member 1 of the rising frame body a.

The support member 1 of the rising frame a is a long member made of an extruded material such as aluminum or an alloy thereof, and has a support edge 1b raised from a substantially horizontal fixed edge 1a, and one side of the upper end of the support edge 1b. A fitting groove 7 into which the airtight material 6 is fitted is formed, and a locking edge 8 whose tip is bent into a hook shape is provided protrudingly. In addition, a water cutter cap engaging groove 9 is formed to open downward at the lower part of the fitting groove 7, and a water stop plate fitting groove 10 is formed upward at the inner end of the fixed edge 1a. The support member 1 is fixed by screwing its fixed edge 1a to an anchor plug buried in the top end of the upright frame a.

The holding member 2 on the side of the wall skeleton a' is also made of aluminum or its alloy, and has a substantially vertical plate-shaped fixed edge 2a with a protruding edge 2c formed at the upper part, and a cover material receiving groove at the lower part thereof. 13 is provided, a water stop plate fitting groove 14 is formed on the lower surface of this receiving groove 13, and a locking protrusion 15 is provided protruding from the upper end of the groove edge 2b constituting the cover material receiving groove 13. The intermediate part of the fixed edge 2a of the holding member 2 is screwed into the anchor plug embedded in the wall structure a' so that the locking ridge 8 of the support member 1 on the side of the frame a and the locking ridge 15 are arranged opposite each other. It is fixed by stopping.

Next, a joint holder 3 is attached to the support member 1 and the holding member 2. The holder 3 is a short metal member having a width of 50 mm to 100 mm and having cover material locking portions 3a bent diagonally downward at both ends.
A spring member 5 made of an elastic body such as a metal spring material is suspended over the support member 1 and the holding member 2.

The spring member 5 is short like the joint holder 3, and has wing pieces 5b bent into a W-shaped cross section on both sides of a central protrusion 5a. It is fixed to the holder 3 by screwing or welding to the bottom surface 3b near the body a'. Note that work holes 3c and 5c are bored in the holder 3 and the wing portion 5b of the spring member 5, respectively.

When installing the joint holder 3 on the support member 1 and the holding member 2, its center part is attached to the airtight material 6 at the upper end of the support member 1 and the locking ridge 15 of the holding member 2.
Press down from above and use jig 1 such as a screwdriver.
1 through the hole 3c, and then press down with its tip against the hole 5c to remove the wing pieces 5b at both ends of the spring member 5.
The locking protrusions 8 and 15 of the support member 1 and the holding member 2
It is sufficient to expand the lower part of the opening and lock the locking protrusions 8 and 15. The joint holder 3 is installed on the support member 1 and the holding member 2 in such a way that it cannot be removed. Since the spring member 5 is an elastic body, even if the supporting member 1 and the holding member 2 approach or separate from each other vertically or horizontally due to an earthquake or the like, and are displaced, for example, as shown in FIG. Securely hold the support member 1 and holding member 2 in the insert holder 3.
Can be held on top.

Note that the holding member 2 and the joint holder 3 are not limited to being directly fixed together by screws or welding. Furthermore, the spring member 5 may have any configuration as long as it has elasticity that can absorb the fluctuations of the frame by itself or in combination with other spring materials, and the joint holder 3 can be held in response to the above fluctuations. However, the present invention is not limited to the example illustrated above.

A long cover material 4 is secured to these joint holders 3. The cover material 4 is made of metal such as aluminum or its alloy or iron, and has a horizontal edge 4a and a substantially vertical upright edge 4b bent into an L shape, and a free end of the horizontal edge 4a has a locking receptacle on the inside. A hanging edge 4c with an edge 17 is formed, and
A weather strip 23 is provided at the upper end of the upright edge 4b.
A fitting groove 24 and a downward projecting edge 25 are formed, and a locking receiving edge 26 whose tip is bent inward from the bend between the upright edge 4b and the horizontal edge 4a is formed.
is formed in a drooping manner. The above locking edges 17 and 2
6 have locking receivers 17a and 26a, respectively.
is formed. When attaching the cover material 4 to the joint holder 3, press down the cover material 4 from above the joint holder 3 and attach it to the locking portion 3a.
The cover member 4 is fitted and locked onto the joint holder 3 by elastically locking its lower end to the locking receiving edges 17 and 26.

Locking receiving portion 1 of locking receiving edges 17, 26 of cover material 4
If sawtooth-like uneven stripes 21 are formed on 7a and 26a, the lower end of the locking portion 3a of the joint holder 3 and each of the uneven strips 21 engage with each other in small increments, so that both members 3 , 4, even if there is a slight error in the dimensions, it can be locked to the appropriate uneven strip 21, so the locking can be finely adjusted, the error can be absorbed, and good locking can be obtained. , which is preferable because it does not cause rattling or the like.

A locking receiving edge 17 is provided on the inner side of the hanging edge 4c, leaving a draining portion 16 at the lower end. Since a gap is provided between the draining portion 16 and the locking receiving portion 17a, rainwater that flows down from the top surface of the cover material 4 along the outer surface of the hanging edge 4c flows down from the draining portion 16. There is no way to go behind the scenes. Further, the hanging edge 4c can reduce the blowing force of wind and rain and prevent rainwater etc. from being sucked in between the frames a and a'.

In addition, abutment edges 18 and 19 are provided protruding from the lower part of the upright edge 4a of the cover material.

Rainwater is drained from the cover material 4 and support member 1 that are installed continuously.
Alternatively, since a small amount of water may enter between the frames a and a' through the joint of the holding member 2, suspend the water stop plate 27 between the supporting member 1 or the holding member 2,
Rainwater falls onto this water stop plate 27 and is discharged outside the frame.

Next, a long draining cap 29 is attached to the rising frame a below the end of the cover material 4. The water-cutting cap 29 is made of metal such as aluminum, and has a raised edge 29b formed at one end of the plate-like main body 29a, and a hanging edge 29c formed at the other end, and the lower end of this hanging edge 29c. A locking receiving portion 29d is formed in a bent manner on the inside. The above raised edge 29b
is engaged in the drainage member engagement groove 9 of the support member 1, and the locking receiving portion 29d of the other hanging edge 29c
is secured to the locking piece 30b of the Kasagi holder and is fitted over the Kasagi holder 30.

Rainwater flowing down from the side edges of the cover material 4 falls on the draining cap 29, further flows along the sloping upper surface, and is led to the inside of the upright frame a.

In addition, an engaging convex portion 29e and an engaging recess 9a are formed at the locking portions of the water cutter cap 29 and the supporting member 1, respectively.
If the air chamber 28 is formed above this locking portion, even if rainwater is sucked in from the locking portion, the suction pressure will be reduced in the air chamber 28, and the rainwater will be transferred to the draining cap 22.
It is better to cover the rain because it will flow down without going around to the back side of 9. It is also preferable to form an uneven strip on the back surface of the lower end of the hanging edge 29c of the Mizukiri Kasagi 29, since even if there is a dimensional error in the Mizukiri Kasagi holder 30 or the Mizukiri Kasagi 29, the two can be reliably engaged in an interlocking manner. .

According to the expansion joint device configured as described above, the joint holder 3 that locks and fixes the cover material 4 is installed on the support member 1 of the upright frame a through the elastic spring member 5.
Even if the building frames a and a' approach or separate due to vibrations during an earthquake, this fluctuation is absorbed by the elastic part of the spring member 5, and the joint holder 3 always maintains a stable standing structure as shown in FIG. It is constructed on the supporting member 1 of the wall and the retaining member 2 of the wall frame. Furthermore, since one side of the cover material 4 is movably supported on the support member 1 of the upright frame a, the engagement between the cover material 4 and the joint holder 3 is always ensured and maintained in a stable state. Ru.

Also, when installing the cover material 4, the cover material 4 is pressed downward along the wall a' surface, but the cover material 4 is attached to the joint holder installed on the support member 1 and the above-mentioned holding member 2. 3, and the locking portions are not biased toward the wall structure as in the past, so there is no need to control the posture of the cover material 4 particularly accurately.
Therefore, the locking operation is also easy.

Furthermore, the other side of the cover material 4 is held by the holding member 2 and is prevented from separating from the wall skeleton a',
Since there is no gap between the wall body a' and the cover material 4, rain protection is also good.

Next, FIGS. 3 and 4 show an embodiment of the second invention. First, in the expansion joint device C shown in FIG.
The structure of the support member 1 above is substantially the same as the example shown in FIG. 1, and therefore is designated by the same reference numerals.

The holding member 35 on the side of the wall skeleton a' has a protruding edge 35b that bends the upper end of the vertical plate-shaped fixed edge 35a to one side to form a downwardly opening locking groove 36, and forms a locking groove 36 at the center of the fixed edge 35a. A locking protrusion 3 with a T-shaped cross section
5c, and a fitting groove 35d for the water stop plate 27, which opens upward, is formed at the lower end. A caulking seal receiving portion 37a is formed at the upper end of the side portion of the projecting edge 35b, and a locking receiving portion 37b is formed at the lower end.

The joint holder 38 has a cover material locking part 38a at one end, and a bent part 38 at the other end.
b, and a spring member 39 having a substantially W-shaped cross section is fixed to the lower part of the spring member 39, as in the example shown in FIG. The bent portion 38 at one end of the joint holder 38
b is locked to the locking protrusion 35c of the holding member 35, and the lower surface of the other end side holds the spring member 39 to the locking protrusion 8, 35c of the support member 1 and the holding member 35.
By being locked to, it is abutted and supported on the support member 1.

The cover material 40 has a raised edge 4 at one end of the horizontal edge 40a.
0b, while the other end has a locking part 41 inside.
A hanging edge 40c is provided, and an engaging protrusion 41a and a bent portion 41b are formed at the upper end of the upright edge 40b. The upright edge 40b on one side of the cover material 40 is locked in the locking groove 36 of the holding member 35, and the hanging edge 40c on the other side.
The locking portion 41 is resiliently locked and fixed to the locking portion 38a of the joint holder 38.

Bent portion 41 at the tip of the upright edge 40b of the cover material 40
b comes into contact with the back surface of the protruding edge 35b constituting the locking groove 36, and an air chamber 42 is formed. For this reason,
Even if rainwater is sucked in from the locking part of the upright edge 4b, the suction pressure is reduced in the air chamber 42, and the rainwater flows down without going around to the back side of the cover material 40, so that the rain can be cleared well.

An exterior material 43 is disposed above the holding member 35, and a caulking sealant 44 is filled between the lower end of this exterior material 43 and the caulking sealant receiving portion 37a of the holding member 35.

Next, also in this example, a draining cap 29 is provided on the standing frame a via a cap holder 30. However, in this example, a fixed edge fitting groove 33 is formed at the free end of the horizontal piece 30a of the Kasagi holder 30,
The fixed edge 1a of the support member 1 is fitted into the fitting groove 33, and the Kasagi holder 3 is inserted from above the fixed edge 1a.
0 and is directly fixed to the upright frame a with screws.

Next, in the expansion joint device D shown in FIG.
Since the cover material 4 and the cover material 4 are the same as those shown in FIG. 3, they are designated by the same reference numerals.

The holding member 45 of the wall frame a' is also third in that a cover material locking groove 46 is formed at the upper end of the fixed edge 45a, and a fitting groove 47 for the water stop plate 27 is formed at the lower end.
Although it is the same as the figure, a locking protrusion 45c that curves downward is formed in the middle part of the fixed edge 45a.

The joint holder 48 has locking parts 48 at both ends.
a and 48b, the locking portion 48a is curved upward, and one end of a U-shaped spring member 49 is fixed to the lower part of the holder 48. One of the locking portions 48a of the holder 48 is attached to the holding member 45.
The other end of the spring member 49 is locked to the locking protrusion 8 of the other support member 1,
As a result, the other end of the holder 48 is supported in contact with the support member 1.

Even in such a mode in which one end of the spring member 49 is fixed to the joint holder 48 and the other end is locked to the support member 1, the wall frame side of the joint holder 48 is rotatably attached to the holding member 45. Since it is locked, it can respond to the displacement of the skeletons a and a'. In addition, as shown by the dotted line, a locking ridge 45'c is formed on the holding member 45, and the other end of the spring member 49' whose one end is fixed to the joint holder 48 is engaged with this locking ridge 45'c. It may also be configured to stop.

According to the expansion joint device shown in FIGS. 3 and 4 above, the joint holders 38 and 48 have their lower surfaces on one end side abutted and supported on the support member 1 by spring members 39 and 49. ,
It can be easily attached by locking the other end to the locking protrusions 35c, 45c formed on the holding members 35, 45. In addition, the cover material 40, 4
When attaching the cover members 40, 4, the holding members 35, 45 side is locked to the above-mentioned holding member, and the supporting member 1 side portion is pushed down to attach the above-mentioned one end of the joint holders 38, 48. The expansion joint device can be reliably installed on the building frame with simple work.

Furthermore, the mutual fluctuation of the building frame is caused by a spring member 39,
49, the joint holders 38, 48 and the cover members 40, 4 are always stably installed over the support member 1 and the holding members 35, 45.

(Effects of the Invention) As explained in detail above, according to the first invention, the joint holder for locking and fixing the cover material is installed on the support member of the upright frame via the elastic spring member. Even if the building frame approaches or separates due to vibrations during an earthquake, this fluctuation is absorbed by the elastic part of the spring member, and the joint holder always stands up stably and is installed on the support member of the frame and the retaining member of the wall frame. be done. Further, since one of the cover members is movably supported on the support member of the upright frame, the cover member and the joint holder are always securely and stably engaged.

Also, when installing the cover material, the cover material is pressed downward along the wall surface, but the cover material is locked to both ends of the joint holder installed on the support member and the above-mentioned holding member. Since the locking portion is not biased toward the wall body as in the conventional case, there is no need to particularly accurately control the posture of the cover material, and the locking work is therefore easy.

Furthermore, the other side of the cover material is held by the holding member and is prevented from separating from the wall structure, and there is no gap between the wall structure and the cover material, so that rain protection is also good.

Next, according to the second invention, the joint holder has the lower surface of one end thereof abutted and supported on the support member by the spring member, and the other end is locked to the locking protrusion formed on the holding member. It can be easily installed by When attaching the cover material, the holding member side of the cover material should be locked to the holding member, and the supporting member side portion should be pushed down and locked to the one end of the joint holder. Therefore, the expansion joint device can be reliably installed on the building frame with simple work.

Further, since the mutual fluctuation of the building frame is absorbed by the elastic portion of the spring member, the joint holder and the cover material are always stably installed on the support member 1 and the holding member.

Therefore, according to the first and second inventions, it is possible to reliably install an expansion/joint device that can sufficiently respond to displacement between the upright frame and the wall frame on a building frame with simple work. You can get the common effect of being able to do it.

Further, since the upright frame side of the cover material is movably provided on the support member, it is possible to sufficiently respond to fluctuations in the building frame.
