Description

[Detailed explanation of the idea] This idea is for ALC (lightweight concrete) for buildings.
This invention relates to a parting edge attachment device that is attached to the lower end of a downhill wall.

The lower end of the ALC descending wall is used to prevent early discoloration, deterioration, damage, etc. due to penetration of rainwater flowing down the outside of the wall, or to support the ceiling material that will be installed on the indoor side of the descending wall. It is desirable to install a parting edge that has the functions of draining and supporting the ceiling material.

By the way, the ALC board that makes up the descending wall is fragile, so it is not possible to directly fix the cut edges to it by nailing or screwing. On the other hand, the lower end of the ALC down wall is usually supported by long angle members. Therefore, it is conceivable to use an angle material to securely and firmly attach the parting edge. One conventional method for attaching the angle member is to screw or weld a bolt to the angle member, attach a holder to the bolt, and attach a parting edge to the holder. However, it is very difficult to screw or weld bolts to existing angle members at precise positions, and the construction is time-consuming.

Therefore, the purpose of this invention is to provide a parting edge mounting device that allows an ALC downward wall parting edge to be attached to an angle material easily and easily without the need for troublesome machining or welding of the angle material. purpose.

In order to achieve the above object, this invention attaches a short locking tool that clamps and fixes the long angle material at the tip of the horizontal edge and the upper end of the vertical edge, and also attaches a short holder to the locking tool. fix it,
A long parting edge is attached to the holder.

However, there are several types of angle materials, each with different widths between their horizontal and vertical edges. In such cases, prepare as many locking tools and holders as there are types of angle materials, so that the parting edge can be installed in the correct position regardless of the type of angle material used. , select the locking tool and holder that corresponds to the type of angle material being used.
Their use is uneconomical in many aspects such as manufacturing costs, storage space, inventory management, etc.

Therefore, this idea was developed to create a parting edge for ALC descending walls that allows the parting edge to be installed at an appropriate position using the same fasteners and holders, regardless of the type of angle material used. The ultimate objective is to provide a mounting device.

Next, an embodiment of this invention will be described based on the drawings.

In Fig. 1, reference numeral 1 is an ALC descending wall, whose lower end is brought into contact with the upper surface of the horizontal edge 2h of the angle member 2 horizontally suspended between columns (not shown), and whose indoor side surface is vertically It is supported in contact with the outdoor side surface of the edge 2p.

Further, reference numeral 3 denotes a locking tool, which is formed into an L-shape approximately similar to the cross-sectional shape of the angle member, and has a horizontal portion 3.
The horizontal edge 2 of the angle material 2 is attached to the outdoor end of h.
The first bent so as to be locked to the outdoor end of h.
It has a locking part 4, and also has a second locking part 5 near the upper end of the vertical part 3p, which is bent so as to lock on the upper end of the vertical edge 2p of the angle member 2. There is. Then, the locking tool 3 pushes the first locking part 4 between the outdoor end of the horizontal edge 2h of the angle member and the lower surface of the descending wall 1, and locks the first locking part to the angle member, The second locking part 5 is connected to the vertical edge 2 of the angle material.
By being locked to the upper end of p, the angle member is clamped from both ends thereof and fixed to the angle member. In this case, in order to ensure the locked state without separating the second locking part 5 from the angle member, it is preferable to fix the upper end 6 of the vertical part of the locking tool to the descending wall 1 with screws 7 or the like.

Reference numerals 8 and 9 are rising pieces provided at two locations separated in the width direction of the horizontal portion 3h of the locking tool, and when the locking tool 3 is attached to the angle material as described above, the rising pieces 8 and 9 As a result, a space 10 is formed between the horizontal edge 2h of the angle member and the horizontal portion 3h of the locking tool. As will be described later, this space 10 is provided with a screw 20 to attach the holder 15 to the horizontal part 3h of the locking tool.
Or, when fixing with rivets, it is a space for the screws or rivets to escape.

As shown in FIG. 2, such a locking tool 3 is made by cutting, bending, cutting, perforating, etc. a single short metal plate, or by processing an extruded material, etc. It can be made by Slit 11,1
Reference numeral 2 is provided to facilitate the bending of the flat plate-shaped locking tool 3 into an L-shape corresponding to the angle member 2. And, as mentioned above,
Since there are multiple width dimensions of the horizontal edge 2h and the vertical edge 2p of the angle member 2, it is necessary to change the L-shaped bending position of the locking tool 3 accordingly. Therefore, the slits 11 and 12 are provided in multiple rows,
The distance from the rising edge 4a of the first locking part 4 to the slit 11 or 12 is 2h of the horizontal edge of the various angle members 2.
is equal to the width of . Further, the second locking portion 5 includes a step portion 5a provided at a position close to the upper end of the vertical portion 3p and a bent tongue piece 5b provided at a position closer to the slits 11 and 12 than the step portion. Depending on the dimensions of the angle member, a step portion 5a or a bendable tongue piece 5b is used.

FIG. 2 shows an example of a locking tool that is formed to be applicable to two types of angle materials in terms of width.

When the angle material 2 has a large width as shown in FIG. 1, the locking tool 3 shown in FIG. The second locking part 5 is locked to the upper end of the vertical edge of the angle member at the stepped part 5a to hold the angle member from both ends, and the screw 7 or the like is used to tighten the locking tool. Down the top end wall 1
sticks to. In this case, since the tongue piece 5b is not used, it remains unbent as shown in FIG.

On the other hand, in the case of the angle member 2A having a small width dimension as shown in FIG. 4 is similarly locked to the tip of the horizontal edge of the angle piece, and the second locking part is made to lock to the upper end of the vertical edge of the angle piece at the tongue piece 5b, so that the angle piece is clamped from both ends thereof,
The locking tool 3 is attached to the angle member 2A by fixing the upper end of the vertical portion to the wall 1 with the screw 7.

In order to make it easier to bend the locking tool at multiple positions, in addition to providing the slits 11 and 12 as in the above example, thin-walled portions (kerfs, narrow grooves) extending along multiple parallel straight lines are formed. You can. Moreover, instead of being composed of the step part 5a and the tongue piece 5b, the second locking part is composed of a screw screwed into a screw hole provided in the vertical part 3p at a position separated from above and below, and the tip of the screw is may be locked to the upper end of the vertical edge of the angle member, or any other locking means may be used.

As mentioned above, by making the locking tool 3 shown in FIG. 2 bendable at multiple positions in the intermediate portion, the first locking portion can be bent even if the width of the horizontal edge 2h of the angle member is different. 4 can be locked to the tip of the horizontal edge of the angle material, and by providing step portions 5a and tongue pieces 5b or screw holes at multiple positions at different heights near the upper end of the vertical portion, This makes it possible to lock the second locking portion 5 to the upper end of the vertical edge of the angle piece even if the width dimension of the vertical edge 2p of the angle piece is different.

In FIG. 2, 13 is a screw hole, and 14 is a screw through hole.

A plurality of such locking tools 3 are attached to the angle member 2 at appropriate intervals in the longitudinal direction of the angle member 2.

15 is a holder fixed to the locking tool;
As shown in FIG. 4, it is formed into a short length, and has a flat attachment part 16 at the middle part in the width direction, a first fixing part 17 on one side in the width direction, and a second fixing part 18 on the other side in the width direction. It has an integrated structure. The mounting part 16 is provided with a long hole 19 that is long in the width direction, and a screw 2 is inserted from the bottom of the mounting part.
0 and temporarily screwed into the screw hole 13 provided in the horizontal part 3h of the locking tool 3, the holder 15 is temporarily attached to the locking tool, and the holder is inserted into the long hole 19.
After moving from side to side through the holder and aligning to the proper position with respect to the descending wall 1, the screw 20 can be finally tightened.

Due to the above structure of the holder 15, the locking tool 3 can be attached to the descending wall 1 as illustrated in FIGS. 1 and 3 due to the difference in width of the angle members as described above.
Even if the holder is installed at a different position relative to the wall 1, it is possible to move the holder left and right in the drawing through the elongated hole 19 and adjust the position so that the holder is always installed at a constant position relative to the wall 1.

The first fixing part 17 and the second fixing part 18 of the holder respectively fix both widthwise ends of the parting edge 21, which will be described later. This is an example of a structure in which fixation is achieved by locking using the material elastic restoring force of the parting edge 21. That is, the first fixing part 17
has an inclined surface 17a that extends toward the outdoors from the lower end to the upper end, and an L-shaped stepped portion 17b that is recessed toward the indoor direction from the upper end of the inclined surface, and
The second fixing portion 18 has an inclined surface 18a extending toward the indoor direction from the lower end to the upper end, and an L-shaped stepped portion 18b recessed toward the outdoor direction from the upper end of the inclined surface.

On the other hand, the parting edge 21 includes a lower wall 22 disposed below the descending wall 1, an outer wall 23 extending upward from the outdoor end of the lower wall, and an upward slope indoors from the upper end of the outer wall. It integrally includes an outer mounting wall 24 that extends as shown in FIG. ing. Note that a draining portion 27 is provided at the lower end of the outer wall 23 and hangs down below the lower wall 22 .

The shapes of the outer mounting wall 24 and the inner mounting wall 26 are also
Various modifications may be made depending on the method of fixing the holder to the first and second fixing parts 17 and 18. FIG. 1 merely shows an example of a shape in which the elastic restoring force of the parting edge is used to lock and fix as described above.

In this way, the parting edge 21 approaches the holder 15 from below, and after locking the tip of the inner mounting wall 26 to the stepped portion 18b of the second fixing part 18, the tip of the outer mounting wall 24 is attached to the inclined part of the second fixing part. The lower wall 22 is pushed up by being brought into contact with the surface 17a and further guided by the inclined surface. The outer mounting wall is an inclined surface 17a
The outer wall 23 and the inner wall 2
5 rooms will be expanded. When the tip of the outer mounting wall comes off the upper end of the inclined surface 17a, the elastic restoring force of the parting edge causes the tip of the outer mounting wall to fit into the stepped portion 17b and be locked.
26 are locked and fixed to the stepped portions 17b and 18b of the first and second fixing portions 17 and 18 of the holder.

In this case, since the lower ends of the inclined surfaces 17a and 18a of the first and second fixing parts of the holder come into contact with the upper surface of the lower wall 22 of the parting edge, vibrations of the parting edge due to wind and building vibrations are prevented and noise is generated. A preventive effect can be obtained.

In addition, a rising wall 2 is provided at the upper end of the outer mounting wall 24.
8 is provided, and the rising wall 28 serves as a caulk receiver when a caulking material 29 is applied between the outer mounting wall and the lower surface of the descending wall 1. Furthermore, by setting the height of the riser surface of the step part of the second fixing part 18 of the holder appropriately high, the ceiling material 30 can be placed on the inner mounting wall 26 of the parting edge, and
It is possible to receive the ceiling material on the riser surface of the stepped portion.

In addition, in order to lock and fix the parting edge 21 to the holder 15, first lock the inner attachment part 26 to the second fixing part 18 as described above, and then lock the outer attachment part 24 to the first fixing part 17. In addition, the outer attachment part 24 and the inner attachment part 26 are simultaneously pushed up along the inclined surfaces 17a, 18a, and almost simultaneously the step parts 17b, 1 are pushed up, respectively.
8b, or, alternatively, after the outer attachment part 24 is engaged with the first fixing part 17, the inner attachment part 26 can be engaged with the second fixing part 18.

In the first embodiment described above, the locking tool 3 was formed completely integrally with the horizontal portion 3h and the vertical portion 3p corresponding to the horizontal edge 2h and the vertical edge 2p of the angle member 2, but as shown in FIG. or as shown in Figure 7,
The horizontal part 3h and the vertical part 3p are formed separately, and the screw 3
It is also possible to use a locking tool 3A that is integrally connected with a rivet or the like. In the case of this second embodiment, the horizontal portion 3h of the locking device is located just a second distance from the first locking portion 4 of the locking device in FIG.
The shape up to the cutting line at the position closer to the locking part 5 is almost the same, and screw holes 32 and 33 are provided near each slit 11 and 12, and the vertical part 3p of the locking tool is is the vertical length of the angle material 2
The second part is bent so that it can be locked to the upper end of p.
It has a simple 7-shaped cross section with a locking part 5, and screw through holes 34, 35 at the lower end.

Further, the second fixing part 18 of the holder 15 in the second embodiment has a substantially J-shaped cross section and has an inclined surface 18a and a stepped part 18b at the tip, and also has a bag part 36 that opens upward. .

In this way, the locking tool is used by bending the end 37 of the horizontal portion 3h opposite to the first locking portion 4 at the slit 12 for the wide angle material 2 as shown in FIG. , the first locking part 4 is locked to the tip of the horizontal edge 2h of the angle member, and the second locking part 5 is locked to the upper end of the vertical edge 2p of the angle member, on the lower side of the vertical part 3p. Insert the screw 31 through the screw through hole 35 and insert it into the screw hole 33 near the end of the horizontal portion 3h.
The horizontal part 3h and the vertical part 3p are integrally connected by screwing the locking tool into the angle member.

Also, as shown in Fig. 6, angle material 2 with a small width
, the horizontal part 3h is bent at the slit 11, and a second locking part 5 is attached to the upper end of the vertical edge of the angle member.
The screw 31 is passed through the screw through hole 34 on the upper side of the vertical portion 3p that is locked, and is screwed into the screw hole 32 near the first locking portion of the horizontal portion 3h to integrally connect the horizontal portion and the vertical portion.

Instead of using the screws 31, it may be fixed with rivets, clips, etc. In addition, the vertical part 3p has an upper part,
Hole 34 instead of providing screw through holes 34 and 35 below
A vertically elongated hole extending from to 35 may be provided.

When attaching the locking tool 3 to the angle member 2 having a small width, the lower end of the vertical portion 3p should extend below the fixed portion 16 of the holder 15, as shown in FIG. However, since the second fixing part 18 of the holder is formed into a J-shape and provided with a bag part 36, and the lower end of the vertical part 3p can be inserted into the bag part, the locking tool and the holder can be attached. There is no problem.

FIG. 8 shows a variation of the second embodiment in which the locking device is constructed by integrally connecting a horizontal portion and a vertical portion. That is, in this example, as shown in FIG. 9, the horizontal part 3h has a structure from the first locking part 4 to the rising piece 9, and the rising piece 9 has a screw hole 3.
8 is provided at the lower end of the vertical portion 3p,
A long screw 39 is passed through one of the lower screw through holes, a vertically elongated hole, a cut groove, etc., and screwed into the screw hole 38.

10 and 11 show a third embodiment of this invention. In this embodiment, the locking tool is separated into a horizontal portion 3h and a vertical portion 3p. The horizontal portion 3h has the same configuration as the horizontal portion 3h in FIG. 9, and the vertical portion 3p also has the same configuration as the vertical portion 3p in FIGS. 5 to 8.

Further, in this embodiment, the holder 15 has a second fixing part 18 having the same shape as in FIG. 8, and a rising part 40 at the indoor end of the fixing part 16.
, and a screw hole (not shown) is provided in the rising portion.

In this way, after the first locking part 4 of the horizontal part 3h is locked to the tip of the horizontal edge of the angle piece and the second locking part 5 of the vertical part 3p is locked to the upper end of the vertical edge of the angle piece, the holder 15 to the horizontal part 3h using screws 20 or rivets at the fixing part 16, and insert thumbscrews 41 or ordinary screws from the screw through holes, vertical holes, grooves, etc. on either the upper or lower part of the vertical part 3p. The holder 15 is fixed to the angle member 2 via a locking member by passing through the holder and screwing into a screw hole in the rising portion 40 of the holder, or by screwing a nut together.

FIG. 10 shows a state in which the angle member 2 is attached with a large width dimension, and FIG. 11 shows a state in which it is attached to an angle member 2 with a small width dimension.

FIG. 12 shows a fourth embodiment of this invention. In this embodiment, the locking tool 3 basically has a horizontal portion 3h and a vertical portion 3p integrally as in the first embodiment, but the second locking portion 5 is connected to the upper end of the vertical portion 3p. Locking pawls 42 and 43 are provided near the vertical edge 2p at different heights according to the width dimension of the vertical edge 2p of the angle member 2, and the locking pawls 42 and 43 are formed separately with an inverted U-shape in cross section, and one end edge 45 has a tip. The insert member 44 has a locking claw 46 at one end thereof, and the other end edge 47 is inserted between the vertical edge 3p of the angle member and the indoor side surface of the descending wall 1.

As shown in FIG. 13, the first locking part 4 of the locking tool
Also, a locking pawl 48 provided at the tip of the horizontal portion 3h, and a locking pawl 50 at one end edge, which has a horizontally L or U-shaped cross section.
The other end edge 51 may be an insert member 49 inserted between the horizontal edge 2h of the angle member and the lower surface of the descending wall 1.

In the embodiment described above, the elasticity and restoring force of both the parting edges 21 are used to connect the first and second parts of the holder 15.
Although the fixed portions 17 and 18 are locked and fixed, the method of fixing the parting edge 21 to the holder 15 in this invention is not limited to the above method, and as illustrated in FIG. Alternatively, it may be fixed by riveting or the like.

As is clear from the above embodiments, the parting edge attaching device according to this invention has a first locking part and a second locking part of a short locking tool at the tip of the horizontal edge and the upper end of the vertical edge of the angle material.
By locking the locking part, multiple locking tools were installed at positions separated in the longitudinal direction of the angle material, a short holder was fixed to each locking tool, and the parting edge was attached to the holder. Firstly, the angle material does not require any processing or welding.
Simply lock and fix the locking tool to the angle material, secure the holder to the locking tool, and attach the edge to this, making it extremely easy and quick to install the edge. Ta.

In the prior art, in which a bolt through-hole is provided in an angle material to secure the bolt, and a holder is secured to the bolt, when the bolt through-hole is drilled, the bolt is brittle.
There is a risk of destroying the ALC descending wall, and the conventional technique of welding bolts to angle members was very troublesome and difficult to work with, but this invention eliminates these drawbacks.

Second, since the locking tool is mounted by sandwiching the angle member from both ends with the first locking portion and the second locking portion, the locking tool can be securely attached to the angle member.

Thirdly, according to this invention, without processing or welding the angle material, using a previously prepared locking tool and holder, the locking tool is locked to the angle material, and the holder is fixed. After that, the parting edges are attached, making on-site construction easy and quick.

As stated in Item 2 of Claims for Utility Model Registration, from the first locking part to the corner of the angle member, the second
If the distance to the locking part can be expanded and contracted according to the width of the horizontal and vertical edges of the angle material, the same locking device can be used even when angle materials with different widths are used. This eliminates the trouble of preparing multiple types of fasteners depending on the width of the angle material.

As stated in Item 3 of the Claims for Utility Model Registration, if the fixing position of the holder to the locking tool is adjustable in the thickness direction of the downward wall, the holder can be fixed even if the width of the angle material is different. By moving indoors/outside as appropriate and adjusting the fixing position, as illustrated in Figures 1 and 3 and Figures 10 and 11, the outer wall of the full cut edge can be lowered to match the outer surface of the wall. It can be adjusted as desired.
