Description

[Detailed description of the invention] This invention has a tongue piece that moves according to the thermal expansion and contraction of the coated metal material by seam welding, is easy to install, has excellent strength, is simple in construction, and is inexpensive. Regarding the movable hanger that can be made.

BACKGROUND ART Conventionally, there have been movable hangers having tongues that move appropriately in response to thermal expansion and contraction of metal plates that undergo large thermal expansion and contraction. Most of these movable hangers have two or more fixed parts with bolts, etc., and depending on the strength of the fixed parts, when actually installed with this, the movable hanger can be fixed by about 20 cm or more. It must be installed at a pitch of 30 cm, and most of the construction work of the coated metal enclosure that serves as a roof or wall using the movable suspenders is spent on installing the movable suspenders.
Not only is the entire construction troublesome, but a large number of mounting bolts and the like are also required, which has the drawback of increasing the overall construction cost. In addition, even in movable parts, durability and strength are required in particular against tensile force (wind pressure (negative)), etc., but there are almost no designs that have been devised other than increasing the plate thickness. Nakatsuta. It is also required that the movable tongue piece be seam welded so that the tongue piece part and the rising part of the covering metal material are attached in a watertight manner.

Therefore, in the present invention, a raised part is formed on one side of the bottom main plate with a mounting hole drilled approximately in the center, and the upper end of this part is folded back to the outside and halfway down the raised part, and a protruding part is formed outward from this lower end. A long hole is formed in the upright part so as to roughly follow the lower surface of the protruding part to form the suspender body, and the front and rear ends of the vertical part are made of a relatively thick metal plate that can be seam welded. at least one end of the movable tongue has a sharp point, a sliding part is formed from the lower end of the vertical part, and a folded edge is integrally formed above and inward from this end, and the folded edge of the movable tongue piece is engaged with the end of the protruding part. First, since the sliding part is slidably provided on the lower surface of the protrusion and in the elongated hole, it can be fixed in only one place, and positioning is easy, and there are fewer parts for mounting bolts. In particular, since the mounting part is located almost directly under the movable tongue, the bending moment value is small, there are many bent parts, and the section modulus is large, so the overall To provide a movable tongue piece which has excellent strength, has an extremely simple structure and can be manufactured at low cost, and eliminates the above-mentioned drawbacks.

Its structure will be explained with reference to the drawings.

It is bent and provided slightly above (floating) the plane of the bottom main plate 1. This protrusion 4 is formed except for the vicinity of both ends in the longitudinal direction (vertical direction in the plane of the paper of FIG. 4) of the upright part 3, and bent pieces 4a are provided slightly below both ends of the protrusion 4 in the longitudinal direction. , a bottom piece 4b may be formed further horizontally from this lower end. (See drawing). This bottom piece 4b is configured to exist on the same plane as the bottom main plate 1. 5 is a long hole,
It is bored in the raised part 3 on the same plane as the lower surface of the protruding part 4, and its length is formed to be approximately equal to the length of the protruding part 4. Reference numeral 6 denotes reinforcing ribs, which are provided around the mounting hole 2 of the bottom main plate 1 (see Figures 1, 2, and 5) or on the front and rear surfaces and ends (see Figure 13).
Each has a bulging formation. This reinforcing rib 6 may not be provided. The main bottom plate 1 with the mounting through-hole 2 and the rising part 3 with the elongated hole 5 and the protruding part 4 constitute a suspender main body A, and the suspender main body A is integrally formed from a single plate material by press working or the like. There are many things. In some cases, they may be processed separately. Also,
The material is made of metal, but stainless steel is particularly preferable due to its durability and corrosion resistance. Reference numeral B denotes a movable tongue piece, which is formed from a relatively thick metal plate that can be seam-welded to other metal plates, and is bent in an inclined or horizontal manner from the lower end of the vertical portion 7 of an appropriate height. A sliding portion 8 is provided, and a folded edge 9 is formed above and inward from the end of the sliding portion 8. A movable tongue B is integrally formed with the vertical portion 7, the sliding portion 8, and the folded edge 9. A sharp portion 7a is formed from at least one of the front and rear ends of the vertical portion 7. That is, there are a plurality of embodiments in which the sharp portion 7a is formed in the vertical portion 7, and the first embodiment has equilateral V-shaped sharp portions 7a, 7 at the front and rear ends of the vertical portion 7.

(see figure). Each sharp portion 7a is provided over the entire vertical length of the front and rear ends of the vertical portion 7 or at a portion excluding the vicinity of the lower end. Movable tongue piece B made in this way
In the embodiment, spring steel or stainless steel is used in terms of durability, strength, corrosion resistance, etc., and it can be seam welded with other metal plates, and the vertical part 7 ends are watertight after welding. A plate material with a thickness of about 1 to 2 m/m was used as it had the conditions to be able to hold it. The folded edge 9 of the movable tongue piece B is engaged with the outer end of the protruding part 4 of the hanger main body A, and is arranged so as to overlap the lower surface of the sliding part 4 and to be slidably inserted into the elongated hole 5. It is being Although not shown, the lower end of the vertical portion 7 of the movable hanger B may be bent in an inclined manner so that this bent portion can slide within the elongated hole 5. In any case, insert the upper end of the vertical part 7 of the movable hanger B into the elongated hole 5 from the lower surface of the protruding part 4, and while rotating it counterclockwise in FIG. is engaged with the outer end of the protrusion 4 to form a movable hanger. Furthermore, in the one shown in FIG. 13, the hanger main body A is formed relatively long, and two movable tongue pieces B are provided in the long hole 5, and the long hole 5 is defined by the solid line. One long hole 5 may be formed continuously as shown in the figure, or two elongated holes 5 may be provided at an appropriate interval as shown by the dotted line. In addition, one mounting hole 2 is provided at approximately the center of the bottom main plate 1, but in some cases, instead of this, end through holes 2a may be formed at two locations on both ends of the bottom main plate 1. (See the dotted line in Figure 13). 10
is a mounting tool such as an anchor bolt or a drill screw, which is used for mounting a movable hanger through its mounting hole 2. Reference numeral 11 denotes a long coated metal material made of metal (stainless steel, etc.), with rising portions 1 on both sides of the main plate 11a.
1b, 11b (flange parts) are formed,
Rising portions 1 of these adjacent coated metal materials 11, 11
1b and 11b are thin materials that can be seam welded (for example,
(approximately 0.3 m/m to approximately 1 m/m), and is seam welded together with the movable tongue B.

Next, the effects will be explained.

First, to describe the construction of a coated metal envelope using the product of the present invention, the coated metal material 11 is placed on the top or side of a steel frame or concrete structure,
A large number of movable hangers are attached at appropriate intervals in the longitudinal direction of the rising portion 11b on one side. To explain this point in more detail, since the vertical portion 7 of the movable tongue B comes into contact with the outer surface of the rising portion 11b,
The bottom main plate 1 is fixed to the top or side surface of the structure, or to the structural material at that location, via a fixture 10 inserted into the mounting through hole 2. At this time, movable tongue piece B
vertical portion 7 and rising portion 11b of coated metal material 11
Sometimes they are temporarily fixed (spot welded, etc.). Next, the adjacent coated metal material 11 is lined up with the front coated metal material 11 so that the rising parts 11b, 11b are in contact with each other, and the movable tongue piece B is inserted between them.
The vertical parts 7 are made to exist, and these operations are repeated in sequence, and then the rising parts 11b and 11b are seam welded (resistance welded) together with the vertical parts 7 to complete the construction of the coated metal envelope. .

As described above, in the present invention, the raised part 3 is formed on one side of the bottom main plate 1, the upper end of the raised part 3 is folded back outwardly downward, and the protruding part 4 is formed outwardly from this lower end. A long hole 5 is formed in the upright part 3 so as to substantially follow the lower surface of the protruding part 4 to form the hanger main body A, and the folded edge 9 of the movable tongue piece B having the vertical part 7 is attached to the protruding part 4. By engaging the four ends and providing the sliding part 8 to be able to slide on the lower surface of the protruding part 4 and inside the elongated hole 5, the part on which the movable tongue piece B slides and the bottom main plate for mounting 1 are separated on both sides with the rising part 3 as a border, and as a result, the structure can be attached to the structure using a single fixture 10 that is inserted through the mounting hole 2 drilled approximately in the center of the bottom main plate 1. It can be fixed to the outside surface or to the structural material at this point, and the present invention eliminates the disadvantage that conventional movable hangers usually have two or more fixing points, making fixing work with bolts, etc. extremely troublesome. Even if it is a movable hanger, it can be fixed at a minimum of one place, positioning is easy, and installation is extremely simple and quick. As a result, the efficiency of constructing the outer enclosure can be greatly improved. Furthermore, since the fixed portion of the mounting through-hole 2 of the bottom main plate 1 is often located approximately directly below or near the movable tongue B, the vertical portion 7 of the movable tongue B is affected by wind pressure (negative ), etc., the bending force (bending stress, etc.) generated on the fixed part of the bottom main plate 1 is relatively small, and this allows the bottom main plate 1 to be made of a relatively thin material with high strength. It is something that can be endured. Therefore, in the conventional movable hanger that is fixed at two places on both ends, there is a movable tongue between the fixed parts at both ends, and the bending force due to the tensile force is large (the fixed part and the line of action are (Due to the large distance between Developed a useful movable hanger. In addition, in the present invention, the vertical portion 7
In particular, even if the metal material is relatively thick and can be seam welded, at least one of the front and rear ends of the vertical portion 7 is formed into a sharp portion 7a, so that the coated metal material 1
When the vertical portion 7 is sandwiched between the rising portions 11b and 11b of 1 and rolled under pressure with the left and right electrode rolls of the seam welding machine, due to the presence of the sharp portion 7a,
The material at the clamping point gradually becomes thicker, and the seam welder's electrical resistance heats it up extremely well.
Continuous seam welding makes it watertight and airtight. This is a vertical part of a relatively thick material, and its end face is formed at a nearly right angle. If this is seam welded, the material suddenly becomes thicker, and heating is insufficient, resulting in incomplete seam welding. Eliminated the shortcomings.
Also, even if only one end of the vertical portion 7 is formed at a substantially right angle, if it comes later in the order of seam welding,
Even the vertical portion 7, which is a relatively thick material, has already been sufficiently heated and can be fully welded. In addition, since the hanger body A has a folded part bent from the upper end of the rising part 2, the part that supports the movable tongue piece B is also strong, and the movable tongue piece B is also made of a relatively thick metal material. It is strong and can be made extremely durable as a whole movable hanger. In addition, when the protruding parts 4 of the bottom main plate 1 on both sides are present with the vertical part 7 as a boundary, the heights at which the adjacent rising parts 11b, 11b of the coated metal materials 11, 11 are lifted are also the same, and the height of the upper end is the same. There are almost no errors,
It can be constructed in an extremely orderly manner, and is also suitable for bending and tightening the area near the upper end. Moreover, when the vertical part 7 is seam-welded to another metal plate in a watertight manner as a welding attachment part of the movable tongue piece B, the movable tongue piece B becomes a hanger due to thermal expansion and contraction of the covering metal plate 11. When sliding on the main body A, the sliding portion 8 and the protruding portion 4 come into surface contact, making sliding extremely smooth. As described above, the movable hanger of the present invention not only has excellent strength and workability, but also has an extremely simple structure, can be mass-produced, and can be provided at low cost.

Note that if the reinforcing rib 6 is formed in a bulging manner on the bottom main plate, the strength can be made even stronger, and if the bent pieces 4a are provided at both ends (front and rear ends) of the protruding portion 4, the outer enclosure can be strengthened. Large vertical loads (snowfall, wind pressure, etc.)
Even if the protruding portion 4 is applied, the protruding portion 4 does not fall down or bend, and the sliding portion 8 can always slide smoothly.
