Description

  The present invention constitutes a building such as piping for various facilities (including ducts) or a cable rack for power line control lines, which is arranged in a building such as a factory building or a warehouse building. TECHNICAL FIELD The present invention relates to a technology for supporting using a steel structure. In particular, the present invention relates to a technique for supporting the equipment piping or the rack using a beam of a steel structure building in which a main structure portion of a column / beam is made of a steel frame material.

  In factory buildings and the like, steel structures (S structures) in which the main structural parts of columns and beams are made of steel frames are often used because of their economical efficiency and the need to ensure a certain level of floor height. In recent years, the pillars and beam members that make up steel-framed buildings are often made of a single material such as H-shaped steel or box steel, but in large buildings such as factories and gymnasiums, Also from the economical aspect, an assembly member composed of a steel material having a small cross section, such as a truss, is used for the beam.

  The truss has a structure in which one construction surface is formed into a triangle shape by a straight material, and the nodes are joined by pin joints. As a member constituting the truss, a shape steel, a flat steel, or the like is used. In particular, when a beam of a factory building or the like that requires a certain degree of strength is used, it is configured using a shape steel.

  When a building beam is a truss beam, the structure of the truss beam is often as follows. In other words, two angle steels with a large cross-section are back to back, and a gusset plate is sandwiched between them to form the upper and lower flanges of the truss beam, and the vertical web that defines the beam back of the truss beam web perpendicular to the upper and lower flanges It is made of two small cross section angle irons with a gusset plate. Then, in the other space of the truss beam web, two small cross-section angle steels as diagonal members are formed as oblique stomach members with different gusset plates interposed therebetween. In the case of truss beams, the upper and lower flanges are called the upper chord material on the upper side and the lower chord material on the lower side.

  When constructing equipment piping or a rack on a steel structure that constitutes a truss beam (hereinafter also referred to as a steel structure) of such a steel structure building, conventionally, a bolt is used as a lower chord material that forms a part of the steel structure. A construction method is adopted in which a hole is opened and the equipment pipe or rack is suspended and held by a suspension member such as a full screw bolt attached to the lower chord material using the bolt hole.

  However, since this method opens a bolt hole in the lower chord material constituting the steel structure, it must be confirmed in advance whether there is an influence on the strength of the steel structure, which is troublesome. In addition, since it takes labor and time to open the bolt holes in the lower chord material, it is a factor that increases the construction period.

  By the way, although it is not equipment piping or rack support from members such as the lower chord material constituting the steel structure that is a truss beam, all the screw bolts that extend from the anchor bolts of the concrete slab have a gap as a primary suspension. General equipment can be installed by hanging two back-to-back angle irons to be fixed in place and suspending all other screw bolts for use in hanging equipment at different positions in plan view. Piping support technology has been proposed (see, for example, Patent Document 1).

As another technique, when the steel beam is made of a single material such as H-shaped steel,
A clamp jig that clamps and fixes the H-shaped steel flange between the gripping member and the tip of the bolt has a structure in which the bolt is fastened to and close to the L-shaped gripping member. There is also a commercially available hanging metal fitting that is hung from the H-shaped steel flange of the beam by sliding and fixing the shaft.

Japanese Patent Laid-Open No. 8-200533

  Equipment piping or racks can be constructed by using the piping support bracket described in Patent Document 1, but how to make this primary from the lower chord material that constitutes the steel structure that is the beam of the factory building of this time There is no disclosure as to whether to attach the suspension base.

  In addition, even if the clamp jig with the H-shaped steel flange of the beam as described above is used as the suspending source, it is only fixed by tightening with bolts. Frequently occur and is not suitable for supporting heavy equipment piping or racks.

  In addition, when using any of the piping support fittings described in Patent Document 1 and the above-described clamp jig, the equipment piping or the rack is suspended below the lower chord material, so the appearance is poor. Not only is this a space-inhibiting factor when using the lower space of the lower chord material. Furthermore, the pipe support fitting described in Patent Document 1 is suitable for suspending a single equipment pipe, but it is difficult to suspend a plurality of equipment pipes or racks.

  Therefore, the problem to be solved by the present invention can be used without processing the members constituting the steel structure, the workability is good, and a plurality of equipment piping can be easily held, An object of the present invention is to provide a pipe or rack support that can shorten the work period.

  In addition, since the steel structure is not processed, and in particular, it is not welded and attached, it is easy to remove or relocate pipes and racks when relocating production equipment due to process changes at the factory. It is to provide a pipe or rack support.

The pipe or rack support of the present invention is placed on an oblique abdomen composed of two angle steels arranged in an inclined manner between an upper chord member and a lower chord member constituting a steel structure that is a truss beam. Used as
The steel structure that is the truss beam is made so that the slanted belly adjacent to at least the web surface direction is perpendicular to the inclination in a C-shape,
Piping or rack support
Two hanging members that are inserted into a gap existing between the two angle steels of the skewed abdomen, and hang down from each of the adjacent skewed abdomen,
A stopper member provided on each of the suspension members for keeping the suspension member in a suspended state in contact with the oblique stomach member,
It is attached to the suspension member so as to connect the plurality of suspension members hanging from the oblique stomach member in a state where the stopper member is in contact with each of two adjacent oblique stomach members so as to form a letter C shape. And a horizontal support member.

  With such a configuration, if the suspension member is inserted into the gap between each of the two angle steels forming the plurality of slanting abdomen adjacent to each other in a letter C shape, the stopper member is slantedly abdomen. Since the suspension member is kept in a suspended state in contact with the material, if a horizontal support member is attached so as to connect these suspension members, an equipment pipe or a rack can be arranged on the horizontal support member.

  The suspension member inserted in the gap between the two angle irons forming the skewed abdomen is held in a suspended state by a stopper member that abuts the skewed abdomen. It can be used without subjecting the member to be processed. Since the suspension member can be arranged without being drilled in the truss beam or bolted to the truss beam, the workability is good and the work period can be shortened. Further, since the horizontal support member can be set to a required length as long as space permits, a plurality of equipment pipes or racks can be easily held.

  Furthermore, if the pipe or rack support of the present invention is used, the equipment pipe or rack can be disposed between the upper chord material and the lower chord material constituting the steel structure, so that the lower space of the lower chord material is provided in the equipment. Piping or rack is not occupied, and space can be used effectively.

  Here, as the stopper member, it is desirable to provide a flat plate stopper member that comes into contact with the upper surface of the oblique stomach member. With such a configuration, since the flat stopper member is in surface contact with the upper surface of the oblique stomach member, the suspension member can be stably held.

  On the other hand, when the roof gradient is a water gradient and the extending direction of the truss beam is orthogonal to the water gradient, the inclination angle of the oblique belly member often varies from truss beam to truss beam. This is because it is advantageous for the convenience of the building that the lower chord material of the truss beam is made constant. Therefore, the angle formed by the suspension member and the horizontal support member can be changed. With such a configuration, when the inclination angle of the oblique belly member is different for each truss beam, various types of pipes in which the angle formed by the suspension member and the horizontal support member is set corresponding to each inclination angle or Since there is no need to prepare a rack support, workability is improved.

  Furthermore, the mounting position of the horizontal support member with respect to the suspension member can be changed along at least one of the longitudinal direction of the suspension member or the longitudinal direction of the horizontal support member. With such a configuration, the mounting position of the horizontal support member can be changed according to the situation at the construction site, so versatility is improved.

  On the other hand, it is also possible to provide a locking member that is disposed on the lower surface side of the oblique stomach member with which the stopper member abuts, and sandwiches the oblique stomach member with the stopper member. With such a configuration, the stopper member is fixed to the oblique abdomen, so that the suspension member can be prevented from floating above the oblique abdomen in the event of an earthquake, improving the earthquake resistance. To do.

  According to the present invention, it is possible to use a member constituting a steel structure, which is a truss beam, without processing, good workability, a plurality of equipment pipes or racks can be easily held, and a construction period is shortened. It is also possible to provide a pipe or rack support that can also be designed.

It is a front view which shows the construction state of piping or the rack support which is embodiment of this invention. FIG. 2 is a partially omitted view seen from the direction of arrow A in FIG. 1. It is a partially cutaway enlarged view of the piping or rack support shown in FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the pipe or rack support tool 100 of this embodiment is disposed in an inclined manner between an upper chord member 11 and a lower chord member 12 constituting a steel structure 10 that is a truss beam. A suspension member 20x (20y) that is inserted into a gap G existing between a plurality of angle irons 13ax, 13bx (13ay, 13by) forming the oblique stomach member 13x (13y) and hangs down from the oblique stomach member 13x (13y). And a flat stopper member 21x (21y) provided on the suspension member 20x (20y) to contact the upper surface of the suspension member 20x (20y) and keep the suspension member 20x (20y) in a suspended state, Hang so as to connect a plurality of suspension members 20x, 20y suspended from the oblique stomach members 13x, 13y in a state where the stopper members 21x, 21y are in contact with the adjacent oblique stomach members 13x, 13y, respectively. Part 20x, and includes a horizontal support member 22 attached to 20y, and.

  The horizontal support member 22 is detachably attached by a plurality of screws 23 in a state where both ends thereof are in contact with the lower ends of the suspension members 20x and 20y. In the present embodiment, the two angle steels 13ax, 13bx (13ay, 13by) forming the oblique stomach members 13x (13y) are L-shaped in cross section, and the webs are back to back. In order to form a gap between the two, the workpiece is integrated with two welded via a spacer, the suspension member 20x (20y) is a strip-like flat plate material, and the horizontal support member is a C channel material, It is not limited to these.

  As shown in FIG. 1, a gap G exists between two angle steels 13ax, 13bx (13ay, 13by) that form a plurality of oblique belly members 13x, 13y adjacent in a letter C shape (see FIG. 2). When the suspension members 20x and 20y are respectively inserted into the stopper members 21x and 21y, the stopper members 21x and 21y come into contact with the upper surfaces of the oblique stomach members 13x and 13y, respectively, so that the suspension members 20x and 20y are maintained in a suspended state. Therefore, if the horizontal support member 22 is attached so as to connect the suspension members 20x and 20y, the facility pipes P1 and P2 can be disposed on the horizontal support member 22. In the present embodiment, the plurality of facility pipes P1 and P2 are mounted on the horizontal support member 22 using the U-shaped bolt 24 and the nut 25, respectively, but the present invention is not limited to this.

  The suspension members 20x and 20y inserted in the gap G existing between the two angle steels 13ax and 13bx (13ay and 13by) forming the oblique stomach members 13x and 13y respectively contact the oblique stomach members 13x and 13y. Since the stopper members 21x and 21y that are in contact with each other are held in a suspended state, the pipe or the rack supporter 100 can be used without processing the members constituting the steel structure 10.

  Further, since the suspension members 20x and 20y can be arranged without being drilled in the oblique abdomen 13x and 13y or bolted to the oblique abdomen 13x and 13y, the mounting workability is good. Also, the construction period can be shortened. Moreover, since the horizontal support member 22 can be set to a required length as long as space permits, the plurality of facility pipes P1 and P2 can be easily held.

  Furthermore, when the pipe or rack support 100 of the present embodiment is used, the equipment pipes P1 and P2 can be arranged between the upper chord member 11 and the lower chord member 12 constituting the steel structure 10 that is a truss beam. Therefore, the facility piping does not occupy the lower space of the lower chord member 12, which is effective for effective use of the space.

  Further, when the pipe or rack support 100 is attached between the skewed stomach members 13x and 13y in the manner described above, the flat stopper members 21x and 21y are in surface contact with the upper surfaces of the skewed stomach members 13x and 13y. Therefore, the suspension members 20x and 20y can be stably held.

  Further, as shown in FIG. 3, flat-shaped locking members 26x and 26y are respectively arranged on the lower surface side of the skewed belly members 13x and 13y with which the stopper members 21x and 21y abut, and between the stopper members 21x and 21y. It is also possible to adopt a method in which the upper surface portions of the oblique stomach members 13x and 13y are sandwiched and tightened with screws 27.

  With such a configuration, the stopper members 21x and 21y are fixed to the upper surface portions of the oblique stomach members 13x and 13y, respectively, so that the suspension members 20x and 20y are located above the truss beams 13x and 13y when an earthquake occurs. Can be prevented, and the earthquake resistance is improved. In this case, as shown in FIG. 2, the widths 21w of the stopper members 21x and 21y and the widths (not shown) of the locking members 26x and 26y are wider than the width 13w (see FIG. 2) of the oblique stomach members 13x and 13y. If the stopper members 21x and 21y and the locking members 26x and 26y can be fixed with the screws 27 in the region outside the upper surface portion of the oblique stomach members 13x and 13y, the screws are secured to the truss beams 13x and 13y. There is no need to open a hole.

  Further, as shown in FIG. 3, since the screw hole 28 formed in the lower end portion of the suspension members 20x and 20y for inserting the screw 23 is a long hole having a long diameter in the vertical direction, the suspension members 20x and 20y. And the horizontal support member 22 can be changed to an angle other than a right angle (for example, an obtuse angle or an acute angle). Therefore, it is necessary to prepare various types of pipes or rack supports 10 in which the angles formed by the suspension members 20x, 20y and the horizontal support members 22 are set in correspondence with the inclination angles of the truss beams 13x, 13y, which differ depending on the construction site. There is no, and workability is good.

  Furthermore, since the screw hole 28 is a long hole whose major axis is the vertical direction, the mounting position of the horizontal support member 22 with respect to the suspension members 20x and 20y is changed along the longitudinal direction (vertical direction) of the suspension members 20x and 20y. Since it is possible, the attachment position of the horizontal support member 22 can be changed according to the situation of a construction site, and it is excellent in versatility.

  The pipe or rack support 100 described with reference to FIGS. 1 to 3 shows an example of the present invention, and the pipe support of the present invention is the pipe or rack support 100 shown in FIGS. It is not limited to.

  The piping support of the present invention can be widely used as a material for equipment piping in buildings such as factory buildings and warehouses.
