Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a fixing device for a support member in an expansion joint.

In general, expansion joints are installed between opposing building frames at intervals. First, a support member is fixed to the end of the building frame along the gap between the building frames. It is constructed by installing cover members having dimensions that can close the above-mentioned gap, but conventionally, when fixing the support members, they are first installed at regular intervals along the longitudinal direction of the building frame. A metal fitting was fixed, and a support member was fixed to this mounting fitting. In this case, the important points are how to attach the mounting bracket to the building frame and how to fix the support member to the mounting bracket, but conventional mounting brackets tend to shift or rotate after installation, or Since the height of the metal fittings is too large, the thickness of the finished frame becomes large, and the supporting member and the mounting metal fittings are not sufficiently fixed.

This invention solves the above-mentioned drawbacks, and provides a fixing device for supporting members at expansion joints, which prevents the mounting bracket from shifting or rotating even after installation, and which allows the finished dimensions of the building frame to be kept low. The purpose is to make suggestions.

An example of implementing the present invention will be described below with reference to the drawings.

In Figure 1, the symbol A indicates the expansion.
Indicates joint. This expansion joint A is placed at the end of building frames 1 and 2 that face each other at a certain distance, such as wall to wall or floor to floor. Support member 1 along
0 and 10 are fixed via mounting fittings 30, and a cover member 20 having a size capable of closing the gap S is provided over the supporting members 10 and 10.

The support member 10 has a base wall 11 that has a substantially inverted L shape.
and a protruding wall 12, and a first engaging edge 13 and a second engaging edge 14 are formed to protrude inwardly from the proximal end of the base wall 11 and the tip of the protruding wall 12, and Second engagement edge 14 at the base end of the base wall 11
A support wall 15 is formed upright on the outside of the support wall 15 , a water stop plate fitting groove 16 is formed outwardly at the base end of the support wall 15 , and a fitting groove for an elastic edge material is formed at the upper tip of the projecting wall 12 . 17, a serrated locking portion is formed at the tip of the support wall 15, and a drainage hole 18 is provided at the base. Support members 10, 10
Support walls 15, 15 and water stop plate fitting grooves 16, 1

A first engagement groove 34 and a second engagement groove 35 that open outward from each other are formed between the engagement piece 33 of and a long hole 36 for a screw is formed in the second engagement piece 33. This is what I did. The lower engagement groove 35 is the mounting bracket 3
The first engagement groove 34 is formed by bending the first engagement piece 32. These first engagement grooves 34 and second engagement grooves 35 are
The first and second engaging edges 13 and 1 of the support member 10
It is provided at a position corresponding to 4. Further, both upper end portions 37 and 38 of the base piece 31 are cut off diagonally. Note that the first engagement piece 32 may be formed to protrude from the upper end of the base piece 31 on the same side as the second engagement piece 33, and the first engagement piece 32 may be formed to protrude from the upper end of the base piece 31 on the same side as the second engagement piece 33. 35
Rather than cutting out the base piece 31, it may be formed, for example, by directly cutting and raising the second engagement piece 33.
Further, the groove widths of the first engagement groove 34 and the second engagement groove 35 may be formed to become narrower from the opening side toward the inner depth. Further, sawtooth-like uneven portions 39, 39 may be formed at the ends of the first engagement groove 34 and second engagement groove 35 of the upper and lower engagement pieces 32, 33. Instead of the uneven portions 39, 39, the side end portions may be formed in an arc shape.

The mounting fittings 30, 30 are attached to the ends of the building frames 1, 2 along the gap S at regular intervals. When fixing the mounting brackets 30, 30, insert the screws 50 through the screw holes 36 of the second engagement piece 33, adjust the position, and fix them to the building frames 1, 2. good. However, it is not limited to this, and for example, building frame 1,
Alternatively, the second engagement pieces 33, 33 of the mounting fittings 30, 30 may be fixed by welding to the different reinforcements 3, 3.

Each of the support members 10 has an inward first engagement edge 13 and an inward first engagement groove 34 and a second engagement groove 35 of each mounting bracket 30, respectively. The two engaging edges 14 are engaged and fixed. When attaching the support member 10 to the mounting fittings 30, the support member 10 is first placed at the S side end of the gap between the building frames 1 and 2, and the first

0 into the first engagement groove 34 and second engagement groove 35, and then attach the mounting bracket 30 to the building frame 1 or 2 as described above.

Thereafter, the upper end of the support member 10 is finished with the exterior material 51.

In this manner, the outwardly facing first portion of the mounting bracket 30
By engaging and fixing the inwardly directed first and second engagement edges 13 and 14 of the support member 10 in the engagement grooves 34 and 35 of the support member 10, respectively, the first In addition, the building frame 1 or 2 is attached to the support member 10 itself.
Since there is no need to provide a special mounting edge for fixing to the holder, material can be saved. Second, the support member 1
0 and the mounting bracket 30 are fixed by engagement, construction is easy. Thirdly, the second engagement groove 3
5 is formed by cutting out the base piece 31 of the mounting bracket 30, it is possible to firmly suppress lifting of the support member 10, and the first engagement groove 34
Since the first engaging piece 32 is formed by bending the first engaging piece 32, the finishing thickness can be small, and chiseling and finishing work can be reduced.
On the other hand, in conventional metal fittings of this type, the upper part of the base piece is formed by notching the upper part of the base piece in the same way as the second engaging groove 35 described above, so the upper part of the upper engaging groove has a dimension to maintain strength. Since the height of the base piece increases accordingly, the thickness of the finished dimension also inevitably increases. Fourthly, when the first engagement groove 34 of the mounting bracket 30 and the upper first engagement edge 13 of the support member 10 engage, the second engagement piece 33 engages with the second engagement edge 14. In addition to being in surface contact with
Since it makes surface contact with the engaging edge 13 of the mounting bracket 30
The contact friction between the support member 10 and the support member 10 is large, and as a result, the mounting bracket 30 may shift laterally after installation.
It never rotates.

Incidentally, the first and second engaging pieces 32, 33 of the mounting bracket 30 have sawtooth-like uneven portions 39, 39 at their side ends.
are formed, these uneven portions 39, 3
9 abuts and bites into the support member 10 when engaged with the support member 10 to obtain a stronger engagement, and when the side end portions are formed in an arc shape, the mounting bracket 30 can be rotated. This will guide you when installing while moving, making installation smoother. Furthermore, even when the groove widths of the first engagement groove 34 and the second engagement groove 35 are formed to be narrower from the opening side toward the inner depths, a similarly strong engagement can be obtained.

Next, as described above, the supporting members 10, 10 provided oppositely to the building frames 1, 2 are provided with elastic holding fittings 60.
The elongated cover member 20 is placed astride the expansion joint A. The elastic holding fitting 60 is a W-shaped, U-shaped, etc. spring member, and has, for example, locking receiving portions 61, 62, 62 formed in opposite directions at the center and both ends, and locking receiving portions 62, 62 at both ends. The support wall 1 of the support members 10, 10
By being engaged with the engagement portions at the ends of the support members 10 and 15, they are attached at regular intervals along the longitudinal direction of the support members 10 and 10. Cover member 2
0 has a width dimension sufficient to cover the gap S between the skeletons,
A locking protrusion 21 is provided on the back surface of the central portion.
By locking this locking protrusion 21 to the locking receiving portion 61 at the center of the holding fitting 60,
The support members 10, 10 are provided astride the protruding walls 12, 12. Note that the projecting wall 1 of the supporting members 10, 10
An elastic edge member 54 is fitted into the fitting grooves 17, 17 at both ends of the members 2, 12, and is interposed between the cover members 20, 20. Further, a water stop plate 55 is fitted into the fitting grooves 16, 16 at the bases of the supporting members 10, 10. As a result, even if the building frames 1 and 2 move in different directions due to uneven settlement, vibration, etc., the cover material 20 is held by the holding fittings 60, and rainwater, dirt, etc. can be removed from the gap S between the frames. Even if water gets in, the water stop plate 55 prevents further intrusion.

In addition to Fig. 1, expansion joints are used to connect building frames 1,
It is also provided when the two body surfaces are perpendicular to each other. This expansion joint B
Also, supporting members 10, 10 are provided on the skeletons 1, 2,
A cover member 20 is placed over these support members 10, 10, and the mounting bracket 30 and support member 10 are attached to one building frame 1 in the same manner as in FIG. 1, so the explanation is omitted. do. Support member 10 attached to the other building frame 2
The supporting member 10 is provided with a support wall 15 and a water stop plate fitting groove 16 by folding back one side end, and a fastening part 71 and an insertion groove 72 are provided on the other side. The wall 15 is fixed to the frame body 2 by screwing the fastening portion 71 to the frame body 2 at a position facing the support wall 15 on the frame body 1 side. The cover member 20 is provided astride the support members 10, 10 via an elastic holding fitting in the same manner as in the above-mentioned example. Note that a bent portion 22 is formed at the end of this cover material 20. Next, the second cover member 25 is attached to the insertion groove 72 of the support member 10 on the frame 2 side. This second cover member 25 is for preventing rainwater etc. from entering between the support member 10 on the side of the frame 2 and the 2nd surface of the frame, and a weather strip 56 or the like is fitted to one end of the second cover member 25. A groove 26 is formed, and an insertion ridge 27 is formed in the center, and the insertion ridge 27 is inserted into the insertion groove 72 and a holding fitting 7 made of an elastic body is formed.
It is attached to the support member 10 by inserting it through 3. Note that the holding metal fitting 73 interposed between the insertion groove 72 and the insertion ridge 27 is attached to the insertion ridge 27 in a manner that cannot be removed, and also engages with the insertion groove 72 in a manner that cannot be removed. In this way, the insert flange 27 is held within the insert groove 72.

When the building frames 1 and 2 move, the expansion joint B does not come off because the bent portion 22 of the cover member 20 engages with the support wall 15 of the support member 10. In addition, when the locking receiving portion 62 of the elastic holding fitting 60 on the body 2 side rises, the second
Since the cover member 25 and the cover member 20 suppress this, the holding fitting 60 is also stably held on the support wall 15.

Note that the support member 10 is not limited to the above-mentioned example; for example, as shown in FIG. It is possible to make changes as appropriate. Further, the other constituent members are not limited to the above-mentioned example, and for example, as shown in the same figure, the cover member 20 may be integrated with the cover member 20 in FIG. 2 and the second cover part 25a, In addition, as shown in FIG.
By forming the engagement protrusion 28 at the upper end of the supporting member 5a, and forming the engagement receiving part 74 at the end of the support member 10, the engagement protrusion 28 and the engagement receiving part 74 are engaged. It may also be configured to be attached to a wire.

As explained in detail above, the device for fixing the support member in the expansion joint according to this invention fixes the support member to the end of the building frame along the gap between the building frames that face each other at an interval. In an expansion joint in which a cover member with a size capable of closing the gap is provided over the support member via a holding fitting, a support member on at least one building frame side is provided on the side remote from the gap. A base wall is provided in a direction away from the one building frame, a projecting wall is formed to protrude from the base wall in an inverted L shape, and a first engagement edge is provided at the base end of the base wall. Formed in parallel on the same side as the above projecting wall,
A hook-shaped second engagement edge is formed from the tip of the projecting wall, and the tips of the first engagement edge and the second engagement edge are formed parallel to each other. A first engagement groove and a second engagement groove are formed in each of the mounting brackets fixed to the building body at intervals, and the first engagement groove and the second engagement groove engage with the first engagement edge and the second engagement edge, respectively. , the first engagement edge and the second engagement edge of the support member are engaged and fixed in the first engagement groove and the second engagement groove, respectively. Therefore, since the support member and the mounting bracket are fixed by engagement, construction is easy. Further, since the engagement groove on one side of the mounting bracket is formed between the base piece and the first engagement piece, the finishing thickness can be small, and chiseling and finishing work can be reduced. Furthermore, when the above-mentioned one engagement groove of the mounting bracket and the first engagement edge of the support member engage, the first engagement piece of the mounting bracket faces the projecting wall of the support member and the engagement edge. Since they are in contact with each other, the contact friction between the mounting bracket and the support member is large, so that the mounting bracket will not shift laterally or rotate after installation.
