Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an expansion joint attachment device.

Generally, a cap is provided at the top of a parapet surrounding the flat roof of a building to prevent rainwater from entering. Such a cap is fixed by being engaged or fastened onto a cap holder fixed at intervals on the top end of the parapet.

Incidentally, a building frame is not necessarily completed in one building, and there are cases where another frame is constructed in the vicinity of one frame, and an expansion joint is erected between these opposing frames to connect both. It is necessary to prevent wind and rain from entering the gaps between the frames. Conventionally, after removing the caps provided on the building frame in advance, supporting members for expansion joints were fixed to the parapets of both building frames, and a cover material was then attached onto the supporting members. However, it is not only a waste of material to remove a Kasagi that can be used in the middle of the process, but also to remove the Kasagi from the Kasagi holder. In addition to removing it from the top of the
Since post-treatment of the fixing hole of the holder is also required, it is complicated and time-consuming, and requires a large amount of removal cost.

The object of the present invention is to solve the above-mentioned drawbacks and, in particular, to propose an installation device for an expansion joint without removing the existing cap.

The present invention will be explained below with reference to the drawings.

In the figure, reference numerals 1 and 1 indicate a rising frame such as a parapet of a building. These standing structures 1, 1
are provided facing each other with a gap S therebetween. At the top end of each frame 1, 1, Kasagi holders 2, 2 are placed at regular intervals along the longitudinal direction.
is fixed in place. This Kasagi holder 2,2
, locking pieces 11, 11 are formed diagonally protruding from both ends of the central fastening pieces 10, 10, respectively, and the above-mentioned fastening pieces 10, 10 rise up and are fixedly fixed to the top ends of the frames 1, 1. As a result, the skeleton 1, 1
A locking piece 11,1 formed to protrude outward from the side surface of
Kasagi 3, 3 are attached to 1, 11. The Kasagi 3, 3 has side plates 13, 14 protruding from both ends of the inclined top plates 12, 12, respectively, to form a U-shape with a downward opening, and furthermore, bending locking parts 15, 15 are provided at the ends of the side plates 13, 14. The locking portion 15,
15 is the locking piece 11, 1 of the Kasagi holder 2, 2.
1 is locked.

It is assumed that the caps 3, 3 have already been installed on the building frames 1, 1 before the expansion joint construction.

Next, when constructing an expansion joint on the opposing rising frames 1, 1, first, a long support member 4 is attached to the opposing side plates 13, 13 of the caps 3, 3 along their longitudinal direction. , 4 are fixed in place. The support members 4, 4 are preferably provided with recesses 16, 16 into which the side plates of the Kasagi are fitted, and a locking portion 17, 17 at the upper part of the gap S side in the figure.
17, airtight mounting edges 18, 18 are formed on the opposite side thereof, and water stop plate fitting grooves 19, 19 are formed in the lower portions of the recesses 16, 16. Although a locking protrusion is formed at the tip of the locking portions 17, 17, a sawtooth-shaped locking uneven surface may be formed on the side surface of the locking portions 17, 17. The support members 4, 4 have recesses 16, 16.
are fitted into the opposing side plates 13, 13 of the caps 3, 3 and fixed to the side plates 13, 13 by screws, rivets, or the like. In this case, a water stop plate 20 is fitted onto each support member 4, 4. By fixing the support members 4, 4, the water stop plate 20 is loosely attached to the gap. At this time, the end of the water stop plate 20
It is preferable to contact the wall surface. In this way, by attaching the support members 4, 4 to the facing side plates 13, 13 of the opposing caps 3, 3, the locking portion 1
7 and 17 face each other with a gap S between the bodies in between. Therefore, the spring members 2 are further attached to the locking portions 17, 17.
A cover material 5 is attached via 1. This spring member 21 is a substantially W-shaped short metal member, and has an upwardly facing locking receiving portion 22 at the upper center and downwardly facing locking receiving portions 23 at both ends. On the other hand, the cover material 5 is a long material having a downward locking protrusion 24 formed at the lower center and airtight members 25 fitted at the lower portions of both sides. When attaching the cover material 5 to the mutually opposing support members 4 and 4 via the spring member 21, the downward locking protrusion 24 of the cover material 5 is engaged with the upward locking receiving portion 22 of the spring member 21. In this state, the cover material 5 is lowered onto the support members 4, 4, and the downward locking receivers 23, 23 at both ends of the spring member 21 are pressed down onto the support members 4, 4.
It is only necessary to engage the locking portions 17, 17 of No. 4 in a spring-like manner. As a result, the cover material 5 is firmly and reliably held by the support members 4, 4 via the spring member 21, and its installation is also easy.

Note that the spring member is not limited to those shown above. For example, as shown in FIG. 2a, the locking receivers 31, 31 at both ends of the spring member 21 are formed to project diagonally upward in the figure,
are locked in advance to the locking protrusions 24 of the cover material 5, and in that state, the spring member 21 is pushed into the gap between the two bodies, and the locking receivers 3 at both ends of the member 21 are held in place.
1 and 31 may be locked to the locking portions 30 and 30. In this case, the spring member 21 may be directly fixed to the cover material 5 by screws, welding, etc. as shown in FIG. Locking wing piece 2 on top
5 is provided in an overhanging manner, and the locking portions 31, 31 at both ends of the spring member 21 are connected to the locking portions 3 on the supporting members 4, 4 side.
0 and 30, and curved locking protrusions 26 and 26 formed at both ends of the cover material 5 may be locked to the locking wing pieces 25.

Further, the supporting members 4, 4 are not limited to those that are directly fixed to the caps 3, 3 by a fixing operation such as screwing or riveting. Kasagi 3 as shown in Figure 3.
An engagement protrusion 32 is formed in advance on the upper part of the side plate 13 of the kasagi 3, while an engagement recess 33 is formed on the support members 4, 4. It can also be fixed by resiliently engaging the engagement protrusion 32 with the lower end of the side plate 13.

Next, when installing an expansion joint using an existing cap, in addition to the above example, for example, as shown in Figure 4, one of the caps The locking portion 35 may be formed integrally with the side plate 13. In this way, if the locking part 35 is integrally formed on the cap 3 in advance, even if other building frames are constructed facing each other at the same time as or after the construction of the building frame 1,
Since the cover material 5 can be immediately attached via the spring member 21 in the same manner as in the illustrated example above,
Expansion joint construction is easy. Note that since the locking portion 35 is provided on the side plate 13 on the outside of the building, there is no problem in terms of safety. Also,
In this case, it is preferable to provide a fitting groove 19 for the water stop plate 20 into which the water stop plate 20 is fitted at the lower ends of the side plates 13, 13 of the caps 3, 3. Note that the opposing skeletons do not necessarily have to be standing skeletons such as parapets. For example, even when a standing wall 1' of another building faces the standing frame 1 of one building provided with a cap 3 as shown in the figure, the supporting member 34 for attaching the cover material 5 is fixed to the standing wall 1'. and the member 34
Even if the locking part 35 is provided opposite to the locking part 35 on the side of the upright frame 1, and the cover material 5 is locked to both the locking parts 35, 35 via the spring member 21 in the above-mentioned manner. good.

Furthermore, the supporting members 4, 4 are not necessarily the Kasagi 3, 3.
It is not limited to those fixed to. For example, as shown in FIG. 5, the supporting members 4, 4 may be fixed to the Kasagi holder 2. That is, engagement protrusions 36, 36 are provided in advance on the upper and lower parts of the inner side of the locking piece 11 on the side of the gap S of the Kasagi holder 2, whereas the support member 4 is bent into a substantially U-shape, and one A locking portion 37a is provided on the locking edge 37, and the other fixed edge 3
8 are provided with engaging portions 39, 39. When attaching the support member 4 to the Kasagi holder 2, the fixed edge 38 is inserted between the locking piece 12 of the Kasagi holder 2 and the frame 1, and the engaging portion 3 of the fixed edge 38 is
9, 39 and the engaging protrusions 36, 36 of the Kasagi holder 2
All you have to do is engage them. This engagement ensures that the support member 4 is attached to the side of the cap 3. The cover material 5 is fitted with the spring member 2 at the locking portion in the manner described above.
