Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is applicable to a material storage area, a warehouse, etc.
The present invention relates to a pipe arrangement shelf for construction, which is installed in a single or multi-tiered stack and can store a large number of pipe materials in a horizontally laminated state.

[0002]

2. Description of the Related Art Generally, pipes used for building materials and piping are stored in a material storage or a warehouse in a bundled state in which many pipes are bundled together. In addition to taking up too much space, this method is dangerous because it tends to collapse if there are too many pipes in a bundle. Moreover, in recent years, it has become more and more difficult to secure such a storage space, and as a drastic measure against this, construction pipe control shelves that can store pipes in a densely stacked state have begun to spread. There is.

As a conventional example of such a pipe arrangement shelf, for example, as shown in FIG. 9, columns a are erected at four corners, and horizontal beams slightly shorter than the pipe length are provided between the lower ends of the left and right columns a, respectively. The member b is integrally mounted by welding,
Pipe support beams c are integrally attached to each other between the lower ends of the front and rear struts a by welding, and a pipe is inserted between the struts a at the four corners, and both ends thereof are supported by the pipe support beams c. It is known that a large number of pipes are supported in a stacked state.

[0004]

However, in the case of the organizing shelves shown in FIG. 9, all the joints of the columns a, the horizontal beam members b, and the pipe supporting beams c constituting the shelves are integrally assembled by welding. However, there is a problem in that many of them cannot be stacked during transportation, and as a result, the transportation cost becomes extremely high. Further, although this kind of shelf is stored in an accumulated state when it is not needed, since it is naturally limited in stacking in multiple stages as described above, it requires a considerably large space for storage.

As a solution to such a problem, conventionally, as shown in FIG. 10, a pipe support beam c is integrally connected by welding between the lower ends of a pair of front and rear columns a which are arranged in parallel to each other. To form the pillar frame body d, the pillar frame bodies d are arranged to face each other on the left and right, and the horizontal beam members b are mounted between the pillars a before and after the pillar frame body d.
The L-shaped connecting fittings e are attached to the upper and lower surfaces of both ends of each horizontal beam member b, and these connecting fittings e and the respective supports a of the support frame body d are attached.
It has been developed that both and are integrally connected and fixed by bolting.

In the organizer having such a structure, since the entire shelf can be separated into the column frame body d and the horizontal beam member b at the time of transportation, a large number of shelves can be transported at a time in a stacked state, and the above-described transportation can be performed. Although the cost problem is solved, on the other hand, after arriving at the installation place such as a material storage area, L-shaped connecting fittings e are attached to the upper and lower surfaces of both ends of the horizontal beam member b by welding or the like. The laborious assembling work of bolting the connecting metal fitting e and each of the columns a of the column frame body d must be carried out at an installation site where favorable conditions are not established, such as in a factory. In addition, there is a problem that a large amount of assembling cost is required because a worker for that purpose must be dispatched to the site.

Further, any of the above-mentioned conventional products can be used by stacking in a plurality of stages, and at the time of stacking, the hanging hook members f welded to the columns a are hung by hanging wires or the like, and each of the upper shelves is lifted. The base leg g provided at the lower end of the column a is fitted to the upper end of each column of the lower shelf so that it is fixed by the weight of the shelf. In this case, the column a is lifted while the shelf is being lifted. If the welding with the work hook member f accidentally comes off, there is a risk of dropping, which is extremely dangerous.

The present invention has been made in order to solve such problems all at once, and it is possible to fold the support frame bodies at the time of transportation and stack them in a multi-tiered manner with a low bulk, and to erect the support frame bodies. It is an object of the present invention to provide a construction pipe organizing shelf which is extremely easy to install and does not require any particular assembly work and is highly safe.

[0009]

In order to achieve such an object, a building pipe control shelf of the present invention is constructed of a pair of front and rear columns 11 arranged in parallel and facing each other as shown in the drawings corresponding to the embodiments. A pair of left and right pillar frames 1 integrally connecting the lower end portions through a pipe support beam 12 is provided, and a shaft support hole 14 is provided in the front-rear direction in the vicinity of the lower end portion of each pillar 11 of these pillar frame bodies 1. Form. A pair of front and rear horizontal beam members 2 which are formed to be slightly shorter than the pipe length are arranged between the left and right support frame bodies 1 having such a configuration, and flat plate-shaped joints are provided on outer surfaces of both ends of the horizontal beam members 2. The metal fitting 3 is integrally fixed in a state of protruding outward and horizontally.

A shaft hole 31 is formed through the joint fitting 3 in the front-rear thickness direction of the upper outer protruding portion, and a lifting hook portion 32 is formed on the horizontal outer protruding portion. 32
A stopper piece 33 extending rearward from the upper edge of the metal fitting, which is almost right above, is provided.

Then, a rotatable pivot shaft 41 that can be tightened is inserted between the shaft hole 31 of the joint metal fitting 3 and the shaft pivot hole 14 provided in each of the columns 11 of the column frame 1, and Support frame 1
Is connected to the front-rear horizontal beam member 2 so as to stand up and down freely with each pair of pivoting pivot shafts 41 as fulcrums, and in the standing posture, the stopper piece 33 provided on the joint fitting 3 and the horizontal beam member. The inner and outer end surfaces of each of the columns 11 are supported by stopper wall portions provided at the left and right ends of the column 2, and the outward collapse of the column frame 1 is restricted from both sides.

In the above structure, the joint fitting 3
Is preferably attached to the horizontal beam member 2 so that the upper edge 34 projects slightly above the upper surface of the column 11 in the lying posture, and by doing so, the upper horizontal beam member 2 when folded and stacked. Since the columns 11 stacked on each other are restricted from moving in the front-rear direction by the projecting upper edge 34 of the joint fitting 3, collapse of the load during transportation can be prevented.

Further, by providing a tension member 5 which is detachably mounted between the front and rear columns 11 of the column frame 1 and which restrains the front and rear columns 11 from tilting outward, an accident may occur. It is possible to prevent the above and become highly safe.

[0014]

[Operation] During transportation, each pivoting support shaft 41 is loosened and the left and right support frame bodies 1 are laid down to be in a folded state in which they are superposed on the upper surface of the horizontal beam member 2 to form a low-profile shape and stack a large number of shelves. Can be loaded on the loading platform in the state.

Further, in a material storage space, a warehouse, etc., the left and right support frame bodies 1 are rotated around a pivoting pivot shaft 41 from a folded state to stand up, and the pivoting pivot shaft 41 is tightened to support the pillar frame body 1. The inner and outer end surfaces of each column 11 are locked to the stopper piece 33 of the joint fitting 3 and the stopper wall portion of the horizontal beam member 2 to prevent falling to the outside and maintain a stable standing state.

On the shelf in which the columns 11 are thus erected, both ends of the pipes P are supported by the upper surfaces of the support beams 12 of the left and right column frames 1 so as to be arranged in the front-rear direction in a bridge state. Further, the pipes P are stacked on a plurality of pipes P arranged in parallel. At this time, the pipes P are supported by the left and right supporting beams 12 and the inner surfaces of the pillars 11 at the four corners, and the stacking state is stable and stable. Be supported by.

Further, when it is necessary to hang up the building pipe organizing shelves according to the present invention by stacking them in multiple stages, when the shelves are to be hoisted, a wire or the like is attached to the hoisting hook portion 32 integrally provided on the joint fitting 3. And hang it up. In this case, even if the joint fitting 3 is detached from the horizontal beam member 2, the stopper pieces 33 are used for the columns of the column frame 1.
Since it is in contact with the outer end surface of 11, the relative rotation of the joint fitting 3 and the support frame 1 around the rotation pivot shaft 41 is blocked,
The lifting hook portion 32 of the joint fitting 3 will be held in the posture when it is fixed to the horizontal beam member 2, and therefore there is a risk that the wire will detach from the lifting hook portion 32 and the shelf will fall. Does not occur.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The building pipe control shelf according to the present embodiment shown in FIGS. 1 to 8 is fixed to a pair of left and right column frames 1, a pair of front and rear horizontal beam members 2 and outer side surfaces of both ends of each horizontal beam member 2. It is composed of four joint fittings 3 for convenience.

Each of the pillar frames 1 is formed by integrally connecting the lower ends of a pair of front and rear pillars 11 arranged in parallel to each other via a pipe support beam 12. Each of the columns 11 is formed by welding a base 13 of a rectangular pipe cut into an appropriate length to a bottom face of a short cylindrical body with a bottom, and as shown in FIG. A shaft support hole 14 is provided in the lower end portion, which is located slightly above, so as to horizontally penetrate the square pipe. Also,
The pipe support beam 12 is made of a rectangular pipe similar to the pillar 11, and is arranged between the front and rear pillars 11 in a horizontal posture, and both end portions are intermediate height portions between the pivot support hole 14 and the base leg 13 on the side surfaces facing the pillar. Is fixed and connected by welding. Also, the pipe support beam 12
Since it is necessary to sufficiently bear the load of the pipe P, triangular reinforcing plates 15 are welded to the outer end face portions of the pipe supporting beam 12 and the column 11. In addition, as the square pipes that form the columns 11 and the pipe support beams 12 of the column frame 1, a thickness of 2.3 mm, a length and width of 50 mm × 50
mm is suitable, and both the column 11 and the pipe support beam 12 are cut to about 800 mm, so that the front-back width of the column frame 1 is about 900 mm.

As shown in FIG. 3, each horizontal beam member 2 is
A pipe support beam 12 between the left and right support frame bodies 1 in a horizontal posture in which the angle steel material is cut to be slightly shorter than the length dimension of the pipe to be loaded, and one surface of the angle steel material is the outer side and the other surface is the upper side. And a stopper wall portion 21 made of a steel plate piece for supporting the end surface of the support column 11 is vertically provided on the lower surface of the upper wall portion by welding at the center of both end portions thereof. .

The angle steel material forming the horizontal beam member 2 has a thickness of 4 in correspondence with the square pipe forming the support frame 1.
mm, vertical and horizontal 50 mm × 50 mm are preferably used. Also,
As shown in FIG. 4, these horizontal beam members 2 are arranged such that the lower surface thereof is slightly higher (about 10 mm) than the upper surface of the pipe support beam 12, and a step D is formed between the horizontal beam member 2 and the pipe support beam 12. It may be attached.

The joint fitting 3 is formed by punching out a metal flat plate such as a steel plate and further bending a part thereof. The lower half one end is welded to the outer surface of both ends of the horizontal beam member 2. As a result, the horizontal beam member 2 is integrally fixed so as to project upward and horizontally outward. That is, as shown in FIG. 5 and FIG. 6, the joint fitting 3 has a shaft corresponding to the shaft pivot hole 14 of each of the columns 11 at a position near the upper center of the horizontal beam member 2 which projects upward. Hole 31
And the hanging hook portion 32 is formed at the end of the horizontal beam member 2 protruding outward in the horizontal direction, and further, the hanging hook portion 32 is formed. The stopper piece 33 is formed by bending a stopper piece 33 extending rearward from an upper edge 34 of the metal fitting which is almost right above.

The lifting hook portion 32 is used for hooking a wire, and is formed by extending inclined guide surfaces 32b and 32c which expand to both sides from an open lower end of an arcuate notch 32a which opens downward. It has a plate hook shape. Further, the stopper piece 33 is a trapezoidal small piece whose inner end side is perpendicular to the upper edge 34 of the metal fitting, and supports the outer end surface of the column 11 to restrict outward fall of the column frame 1. is there.

The left and right support frame bodies 1 configured as described above
The front and rear horizontal beam members 2 are connected to the shaft holes 31 of the joint fittings 3 attached to the outer surfaces of both ends of the horizontal beam member 2 and the support frame 1
The pivot shafts 41 having male screw portions 41a on the tip side are inserted through the shaft supporting holes 14 provided in each of the columns 11, and the male screw portions 41a protruding to the side faces facing the column are inserted. By screwing nuts 41b to the left and right columns, the left and right support frame bodies 1 are connected to the front and rear horizontal beam members 2 so that they can be erected and tilted up and down with each pair of front and rear pivoting pivot shafts 41 as fulcrums.

In this case, the peripheral portion 16 of the opening of the shaft pivotally supporting hole 14 provided in each of the columns 11 on the opposite side surface side is about the thickness of the nut 41b or the thickness of the head of the pivoting and supporting shaft 41. By making the concave deformation, it is possible to avoid the nut 41b or the protruding male screw portion 41a of the pivoting pivot 41 from interfering with the peripheral surface of the pipe loaded between the pipe support beams 12, and the pipe loading space between the front and rear columns 11 is prevented. Can be effectively used without waste, and the rotary pivot 41
It is possible to eliminate the risk of damaging the peripheral surface of the pipe P that is arranged so as to face the distal end of the pipe P. 41c is a washer.

Further, as shown in FIGS. 7 and 8, when the support 11 is laid down about the pivot shaft 41, the joint fitting 3 projects slightly higher than the upper surface of the support 11 by a height H (about 10 mm). When the shelves are stacked in multiple stages in a folded state, the columns 11 stacked on the horizontal beam member 2 on the upper stage move forward and backward on the projecting upper edge 34 of the joint fitting 3. Since it is regulated, the collapse of the load during transportation is prevented, which is convenient.

Reference numeral 5 denotes a tension member made of a strip-shaped thin metal plate, which is continuous on both sides of the erected portion 51 having a length substantially equal to the front and rear strut outer end face intervals of the strut frame body 1 and the outer peripheral portion of each strut 11. A U-shaped engaging portion 52 that engages in a hug shape is formed by bending, and is detachably attached between the front and rear columns 11 of each column frame 1 at an appropriate intermediate height position. It regulates the inward tilt of 11. Incidentally, it is also possible to use the pulling member 5 in combination to form hooking holes 17 in the vicinity of the upper end of each of the columns 11, and to hook a hooking bar between the hooking holes 17.

When the pipe P organizer of the present embodiment constructed as described above is loaded on a loading platform such as a truck and conveyed, as shown in FIG. A plurality of shelves are stacked in multiple stages on the loading platform in a low bulk folded state in which the beams are superposed on the upper surface of the beam member 2. At this time, the horizontal beam member 2 of the upper shelf is overlaid on the collapsed column 11 of the lower shelf, but in this folded state, the horizontal beam member is below the shaft support hole 14 of the column 11. The end portion of the horizontal beam member 2 is adjacent to the inner end portion of the joint fitting 3 in the front-rear direction. Therefore, by stacking the ends in the lengthwise direction of the respective shelves so that they are aligned in the vertical direction, the ends of the horizontal beam member 2 in the upper stage closely oppose the projecting upper edge 34 of the joint fitting 3 in the lower stage and move forward and backward. Since the movement in the direction is restricted, a stable loading state can be obtained.

Next, when the left and right support frame bodies 1 are rotated from the folded state around the rotation pivot shaft 41 to stand up in a material storage space or a warehouse, the respective support columns 11 of the support frame body 1 are substantially upright. By the way, both the inner and outer end surfaces thereof are locked to the stopper piece 33 of the joint fitting 3 and the stopper wall portion 21 of the horizontal beam member 2 to prevent falling outward, and maintain a stable upright state,
A pipe loading space is formed between the pillars 11 at these four corners. When the pipes P are stacked in this pipe loading space, the pipe groups in the lowermost layer are arranged in parallel in the front and rear in a bridge state in which both ends in the length direction thereof are placed on the upper surfaces of the pipe support beams 12 of the support frame body 1. By sequentially loading the pipes P in the same direction on the pipe group of the lowermost layer, the pipes P located at the front and rear ends of each layer are supported by the inner surface of each of the columns 11 of the column frame 1 at the peripheral surfaces at both ends. Therefore, they are loaded and stored in a stable state in which the load does not collapse.

When a plurality of shelves are stacked vertically and used, a wire or the like is hooked on the hoisting hook portion 32 integrally provided on the joint fitting 3 and the hoisting hook portion 32 is lifted. The base legs (13) are fitted into the upper ends of the columns (11) of the lower-level organizing shelves located directly below the base legs (13). At the time of this lifting, even if the welded portion between the joint metal fitting 3 and the horizontal beam member 2 is disengaged, the stopper piece 33 of the joint metal fitting 3 is in a locked state with the outer end surface of each of the columns 11 of the column frame body 1. , The joint fitting 3 is rotated to lift the hook portion 32 for lifting.
The risk that the wire will come off is prevented as much as possible.

[0031]

As described above, in the architectural pipe organizing rack of the present invention, the lower ends of a pair of front and rear columns that are arranged in parallel and opposite to each other are integrally connected through the pipe supporting beams, and the lower ends of the columns are also connected. A pair of left and right support frame bodies with axial support holes formed in the front-rear direction are provided near the pipe section, and a pair of front and rear horizontal beam members formed slightly shorter than the pipe length are provided between these support frame bodies, and Plate-like joint fittings are integrally fixed to the outer surfaces of both ends of the beam member in a state of projecting outward and horizontally outward, and further, the joints of the joint fittings are penetrated in the front-rear thickness direction. Rotating pivot shafts that can be tightened are inserted between the shaft holes provided and the shaft supporting holes provided in each of the columns, and the column frames are pivoted to the front and rear horizontal beam members by pairs of pivots. While standing up and down using the pivot as a fulcrum,
A lifting hook portion is formed on the horizontal outward projecting portion of each of the joint fittings, and a stopper piece for supporting the outer end surface of the strut is provided rearward from an upper edge of the fitting, which is substantially directly above the hook portion. A stopper wall portion is provided at each of the left and right end portions of the horizontal beam member to support the support end face, and the stopper pieces and the stopper wall portion are configured to restrict outward collapse of the support column body from both sides. Therefore, when transporting or when not in use, the left and right column frames can be laid down and stacked on the upper surface of the horizontal beam member in a low-volume folded state, so that a large number of shelves can be stacked and stacked on the loading platform. In a storage space, a warehouse, etc., the left and right support frame bodies are rotated around the pivot support shafts to stand up, and the rotation support shafts are tightened, so that each support column of the support frame body has its inner and outer end surfaces joined by joint fittings. of Locked on the stopper walls at both ends of the topper piece and horizontal beam member to prevent falling to the outside and maintaining the upright state, a large number of pipes piled in a bridge state between the upper surfaces of the support beams of the column frame at the four corners. Can be supported on the inner surface of the column.

Therefore, unlike the conventional shelving in which all the connecting portions of the columns, the horizontal beam members and the pipe supporting beams are welded and integrally assembled, a large number of shelves are required for storage during transportation or when not in use. Since it can be stacked in multiple stages in a safe state in which the load does not collapse easily, the transportation cost can be reduced and the storage space can be reduced as much as possible. In addition, since it can be assembled at the manufacturing site in advance, and at the installation site, it can be put in use by a simple operation of raising the support frame and tightening the pivot shaft, so that it can be seen in the conventional improvement example. It is not necessary to perform an assembly work at the installation site by mounting a metal fitting for connecting the support frame and the horizontal beam member, and the installation work can be performed quickly and efficiently.

Further, when the hoisting work is carried out as in the case where the building pipe control shelves of the present invention are stacked and installed in multiple stages, a wire or the like is hooked on the hoisting hook portion provided integrally with the joint fitting. Even if the joint fitting is detached from the horizontal beam member at that time, since the stopper piece is in contact with the outer end surface of each strut of the strut frame body, the joint fitting and the strut frame body cannot be rotated. The relative rotation around the pivot axis is prevented, and the lifting hook portion of the joint fitting is held in the posture when it is fixed to the horizontal beam member. Therefore, the wire is the lifting hook portion. There is no danger of shelving being dropped from the shelves, and it is highly safe.

According to the second aspect, since the upper edge of the joint fitting is configured to project slightly above the upper surface of the column in the lying posture, when folded and stacked, it is superposed on the upper horizontal beam member. Movement of each of the supported columns in the front-rear direction is restricted by the protruding upper edge of the joint fitting, and as a result, collapse of the load during transportation can be prevented.

Since the pulling member according to claim 3 is detachably mounted between the front and rear columns of the column frame, the outward tilt of the front and rear columns is restricted, so an accident is prevented. It can be done and the safety can be made more reliable.
