[0002]

2. Description of the Related Art Conventional techniques of this type include those shown in the upper portion of FIG. 8 and FIG. 11 and those shown in FIG. In the former case, a bracket G is provided at a desired height position of a column F made of H-shaped steel, and a hanger rail (raceway) H is attached to the pillar F. For example, three pipes J1, J2, and J3 are respectively attached to a hanger saddle (raceway saddle). ) I1, I2, I
It is designed to be fixedly supported by 3. The hanger rail H is elongated and has a uniform cross-sectional shape, and the cross-section perpendicular to the longitudinal direction is a groove-shaped one as shown in FIG. 11 (b). It has a groove type engaging portion formed in the joining portion 11. As shown in FIG. 11, the hanger saddles I1, I2, I3 are two sets of the same shape and are a set of press-formed products, and the sizes thereof are slightly different depending on the diameter of the pipe to be fixedly supported. A tightening portion 13 having an arcuate portion of a predetermined width in contact with the ¼ circumferential surface of the corresponding pipe, and having a through hole for the tightening bolt 12 bent and extended at one end thereof, and the arcuate portion It has an engaging portion 14 which extends linearly from the other end and is formed by a notch to engage with the engaging portion 11. In the figure, reference numeral 15 denotes a nut, which can be fixedly supported on the hanger rail H by being screwed into the bolt 12 and tightened. The hanger rail H is fixed to the bracket G by welding or bolting, and the bracket G is fixed to the pillar F by welding.

The latter shown in FIG. 12 is another conventional example, in which the hanger rail K has a substantially U-shaped cross section and the engaging portion 1
6 has a circular hole type engaging portion which is a circular hole. A round clip M is used as the one corresponding to the hanger saddle I1. The circular clips M are two presses of the same shape and are a set of press-formed products.
It has a circular arc-shaped portion of / 2 arc, has the same tightening portion 13 as described above at one end, and has an engaging portion 17 that engages with the engaging portion 16 at the other end. In this case as well, the pipe J can be fixed to the hanger rail K by screwing the bolts 12 and the nuts 15 together and tightening in the same manner as described above. Like the hanger rail H, this hanger rail K is also attached to the bracket G or the like for use.

[0004]

The conventional pipe support is installed with the bracket G provided on the pillar F when the pipe is horizontally piped along the wall portion of the steel frame building. It projects into the internal space. As shown in FIG. 11A, the wall portion of the steel frame building welds a horizontal member C made of C-shaped steel to a pillar F, and the horizontal member C is hook bolt 18, packing 19, washer 20, Generally, a configuration in which the corrugated slate A is attached by using the nut 21 or a configuration in which a corrugated steel plate or a corrugated steel plate, which is not shown, is attached to the lateral member C by a steel screw is general. The configuration in which the piping part projects into the interior space of the building, when the lift is used in the building,
There is a problem that it hinders lift work and damages the pipes and brackets. Further, when the pipe is supported between the pillars, the support interval becomes wide, so that it is necessary to separately provide a bracket mounting portion, and even if the bracket is projected from the lateral member C, it is possible to project it at the same position as the bracket of the pillar F. Since it is necessary to project the width of the column F excessively, the projection amount becomes large, and it is difficult to manufacture a column having sufficient strength. Furthermore, it also interferes with lighting. Furthermore, when the bracket G is attached to the pillar F, the strength of the pillar is lowered when bolted, and the strength of the pillar is reduced. When welding is performed by either electric or gas welding, the paint of the pillar is burned, and the flammable matter is also burned. There is a problem that it cannot be used in a certain factory or warehouse. An object of the present invention is to solve the above problems.

[0005]

The three-dimensional pipe supporting fixture of the wall portion of the present invention is substantially L-shaped so that both sides surround a square outer peripheral portion of a predetermined steel material forming the wall portion. A first part and a second part, each of which has a band shape and has a hook part that engages with each other at one end and a clamp part that bends and extends outward while maintaining a facing state at a small gap from each other at the other end; , A clamping bolt provided so as to tighten both tip portions of the clamp portion in a direction in which the small gap becomes smaller, and the clamp portion holds one end of the hanger rail between the small gaps of the tip portions. It is characterized in that it is formed so as to be held in the inner surface side concave portion of the corrugated wall material which is attached by bringing the inner surface side into contact with the predetermined steel material in a held state.

[0006]

The wall body using the corrugated wall material is usually a horizontal member made of steel in such a manner that the pillars of the H-shaped steel are connected in parallel to each other at appropriate intervals in the vertical direction on the outer surface (corrugated wall material side). And a corrugated wall material is attached to the lateral member with hook bolts or steel screws. A C-shaped steel material or a square steel material (square pipe) is used for the lateral member. The three-dimensional pipe support fixture of the wall portion of the present invention (hereinafter abbreviated as fixture) is used in two sets up and down to fix one hanger rail at a desired position. Prepare a hanger rail that has a groove type engagement part with a length slightly shorter than the interval between parallel steel materials in the wall body, and correspond the hanger rail to an appropriate recess of the corrugated wall material between the steel materials. Place it in the position you want. The steel materials at the positions corresponding to both ends of the hanger rail are surrounded by the fixtures of the present invention with their clamps positioned in the recesses where the hanger rails are located, and the clamps are tightened with tightening bolts. As a result, the fixture bites the groove bottom at the end of the hanger rail at the tip of the clamp portion and fixes the fixture to the steel material. In this fixed state of the hanger rail, the clamp portion and the groove bottom side portion of the hanger rail are located in the recess of the corrugated wall material. The pipe can be fixedly supported on the hanger rail by a hanger saddle. The pipe passes between the pillar and the corrugated wall material. The maximum outer diameter of the pipe that can be piped in this way is the width of the steel material that regulates the space between the column and the corrugated wall material, minus the dimension of the hanger rail protruding from the recess of the corrugated wall material. Is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. 1 to 3 and 5 to 10. The fixture T of this embodiment is applied when the lateral member forming the wall portion is C-shaped steel. As shown in FIG. 1 and FIG. 3, its structure is composed of a first part 1, a second part 2 and a tightening bolt 5. Each of the first part 1 and the second part 2 is formed by press-forming a steel plate, has a band shape of a predetermined width, is bent into an L-shape corresponding to the outer circumference of the C-shaped steel, and has a hook portion 3 at one end thereof. Clamps 4 and 4 are formed so that they can be engaged with each other in a releasable manner so as to surround the outer periphery of the C-shaped steel, and the other end is opposed to each other with a small gap therebetween. A large number of small anti-slip projections 6 are provided inwardly on both side edges of each L-shaped bent portion. Further, a circular hole 7 for engaging the circular hole engaging type round clip M described above is provided at the center of each of the L-shaped bent portions. The engagement state is as shown in FIG. 2, which will be described later.

The clamp portions 4 and 4 are parallel to each other and extend a little outward in the corner portion, in the direction of a substantially diagonal line, and L
The bite portion 8 extends outward in the direction along the short side of the letter-shaped side, and the second component side terminates as it is, and the first component side bends toward the bite portion 8 and slightly protrudes. It is used as the bite section 9. In the portion extending outward in the direction along the short sides of the clamp portions 4, 4, a screw hole is provided on the first component 1 side so that the gap between them can be tightened in the direction of closing the same. The bolt 5 is inserted.

A second embodiment of the present invention is shown in FIG. The mounting tool T1 of this embodiment is applied when the lateral member constituting the wall portion is a square steel material (square pipe having a square cross section). The configuration is different from that of the first embodiment only in that the sides of the L-shaped portions have the same side length. Therefore, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Also, since the usage state is the same as that of the first embodiment, the first embodiment will be described below and the description of the second embodiment will be omitted.

As shown in FIG. 8, FIG. 9, and FIG. 10, the wall portion using the normal corrugated wall material has an appropriate vertical interval on the outer surface (corrugated wall material side) of the column F of H-section steel. Lateral members made of C-shaped steel C are welded in parallel with each other so as to connect columns, and corrugated wall material A (Fig. 8 is a square corrugated steel plate, Fig. 9 and Fig. 10 is a corrugated slate). Is attached using a hook bolt 18, a packing 19, a washer 20, and a nut 21. Although a C-shaped steel material or a square steel material (square pipe) is used for the lateral member, a hook bolt is similarly used for the structure to which the corrugated wall material A is attached.

On a wall body made of square corrugated steel plate, a fixture T, a conventional hanger rail H and a hanger saddle I are used.
1, I2, I3, and the pipe J along the wall
FIG. 8 shows an example in which the piping of 1, J2, and J3 is performed. Figure 8
The upper part of FIG. 1 is the above-mentioned conventional example, and the usage example of the first embodiment is shown on the lower side thereof. The C-shaped steel C is provided in parallel with the upper part and the middle part of the figure, and as shown in the enlarged view of FIG. 5, the fixtures T, T are installed on the C-shaped steel C, and the hanger rail is further provided. The hanger rail H and the fixture T itself are fixed by holding the groove bottoms at both ends of H between the holding portions 8 and 9 with tightening bolts. Using the hanger saddles I1, I2, I3 on the hanger rail H, the pipes J1, J2, J
3 is fixed. FIG. 6 shows a state in which the lower end of the hanger rail H is fixed to the C-shaped steel C on the lower side by a mounting tool T. In the figure, d is a corrugated concave portion, e is a corrugated convex portion, and the clamp portion 4 is inside the corrugated concave portion d.

On a wall portion using a corrugated slate, a fixture T, a conventional hanger rail H and a hanger saddle I are used.
1, I2, I3, and the pipe J along the wall
9 and 10 show examples in which the pipes 1, J2 and J3 are provided. The difference between the one using the above-mentioned square corrugated steel sheet and the one using the corrugated slate is only that the cross-sectional shapes of the concave and convex portions of the corrugation are different, but in detail, FIG. 7 and FIG. 9, as shown in FIG. FIG. 7 shows a state in which the fixture T is installed on the lower C-shaped steel C. The clamping part 4 is in the corrugated recess d. e is the convex portion of the waveform.

In the above-described use example, the clamp portion 4,
When 4 is formed so as to fit properly in the corrugated recess, most of the hanger rail H can also be fixed in the recess so that it protrudes about 5 mm from the surface connecting the protrusions.
This projection is necessary because the pipe abuts and is fixed to the hanger rail H, but it is preferable that the projection amount is as small as possible because a thicker pipe can be piped. That is, the maximum thickness of the pipe that can be piped is, as can be understood from FIG. 9, the width of the C-shaped steel C, which is the lateral member, minus the protrusion amount of 5 mm. The dimensions are usually 50 to 100 mm, with a pipe outer diameter of 45 mm possible for 50 mm and a pipe outer diameter of 95 mm for 100 mm.

Further, although the above is the case where the inner side wall is not provided, the inner side wall may be provided, and in that case, since it is usually provided so as to connect the pillar F in contact with the inner end edge of the lateral member, The hanger saddle clamp 13 must not interfere with the inner wall. In that case, since a conventional bolt hanger saddle saddle is used, the maximum thickness of the pipe that can be piped is the same as when the inner wall is not provided. The set bolt diagonal hanger saddle has the tightening portion 13 at a position displaced by about 80 ° around the pipe, and the two members are asymmetric. If you do not use such a special fastening bolt diagonal hanger saddle, that is, if you use a hanger saddle I1, I2, I3 shape, the maximum thickness of the pipe that can be piped from the above dimensions Projection size of tightening part 13 (18m
m) will be further subtracted. Therefore, when the width of the C-section steel C is 50 mm, the pipe outer diameter can be 27 mm, and when the width is 100 mm, the pipe outer diameter can be 77 mm. The width of the ordinary member is often 100 mm, and it is possible to pipe up to 77 mm in outer diameter of the pipe, and a pipe having an outer diameter of 63 mm which is often used can be piped. This point is possible because most of the hanger rails H enter the recesses of the corrugated wall material. That is, the thickness of the hanger rail H is 20 to 25 mm, and in the structure in which the hanger rail H does not enter the recess at all, the outer diameter of the pipe that can be piped is reduced by 15 to 20 mm.

Therefore, by using the fixture T, the space between the pillar F and the corrugated wall material can be effectively utilized, and since it does not project to the inside of the pillar F, it does not interfere with the lifting work and obstructs the illumination. It is possible to install a hanger rail in an arbitrary recessed position of an appropriate corrugated wall material between columns and to obtain a sufficient pipe support action, and do not attach a bracket to the column during construction. Therefore, no welding or drilling of bolt holes is required.

As shown in FIG. 2, the fixture T is not limited to such a use example, but a hanger rail is not used and a conventional circular hole engagement type hanger saddle M is used to pipe a C-shaped steel C. J4 can be piped along the underside of C-section steel C. Further, when the inner wall is not provided, a vertically rising pipe like the pipe J5 is also possible.

In the above embodiment, the first component 1 and the second component
Although the component 2 is provided with the small anti-slip projections 6 and the circular holes 7, these are provided as needed, and are not always necessary when used exclusively for fixing the hanger rail, and can be omitted. .

[0018]

When the fitting of the present invention is used, the C-shaped steel material or the square steel material (transverse member) that constitutes the wall portion is formed along the inner recess of the corrugated wall material forming the outer wall. The hanger rail can be fixed with most of it inside the recess and the pipe is fixed to this hanger rail by the hanger saddle, so the distance between the hanger rail and the pillar can be widened, and the outer wall and the pillar A wide piping space can be obtained between them. Moreover, the pipe is in a state in which the pipe is located between the inner surface of the outer wall made of the corrugated outer wall material and the surface connecting the pillars, and does not project inward from the pillars, so that it does not interfere with the lifting work and the lighting It does not interfere. In addition, since the bracket for installing the hanger rail is not attached to the pillar, there is no need to weld it to the pillar or drill a bolt hole, and screwing is the main work, which makes piping work easier. , Higher safety. Also, the pipe can be hidden when the inner wall is installed.
