Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support rack for a unit room used in a unit room such as a bathroom unit or a shower room unit.

[0002]

2. Description of the Related Art For example, as shown in FIG. 10, a supporting frame for suspending a bathroom unit has a pair of horizontal load receiving members 100 for supporting floor pans or the like. It is supported by a support member 101. The load receiving member 100 and the support member 101 are generally joined by welding.

That is, the support base is positioned by using jigs or the like in a state where the support members 101 are brought into contact with both ends of the load receiving member 100, and these are welded and joined, and then a sander or the like is used. It is manufactured by applying a rust preventive agent to the welded portion W after removing spatter and the like.

[0004]

However, in order to extend the demand for a unit room such as a bathroom unit in a recession, it is desired to reduce the cost as much as possible without lowering the performance of the product. It is desired that the cost of the unit frame support frame be reduced by reducing the number of manufacturing steps and the like.

[0005] Further, in the above-described support gantry, if there is a welding defect such as a missing welding portion in the welded portion W, the welded portion W cannot transmit the force on the load receiving member 100 side to the support member 101 side. Since the load receiving member 100 may come off the support member 101, it cannot be said that there is no safety problem.

SUMMARY OF THE INVENTION In view of the above, the present invention can reduce costs by reducing the number of manufacturing steps and the like. It is intended to provide a support base.

[0007]

According to the first aspect of the present invention, a horizontal load receiving member is supported by a pair of support members suspended on a base of a building or installed on a mounting surface of a unit room. In the support frame for unit room in which both ends of the member are supported, the positioning and support are inserted into the holes of the support member until the insertion restricting portion abuts against the support member at the end of the load receiving member. Is formed.

According to the present invention, the load receiving member can be positioned by inserting the projection of the load receiving member into the hole of the support member and abutting the insertion restricting portion against the support member. When joining the support member and the support member, the load receiving member can be positioned on the support member side with a jig that presses the load receiving member toward the support member. Therefore, according to the present invention, the positioning jig for positioning the load receiving member and the support member at the time of joining can be simplified, and the positioning of these members can be performed in a short time.

Further, according to the present invention, since the projection of the load receiving member is supported on the support member side through the hole, the load receiving member and the support member are not sufficiently joined by the joint. Also, the load receiving member moves from the support member side,
It will not come off.

Here, the load receiving member and the supporting member can be formed of a bent steel plate, a shaped steel or the like.
The number and shape of the projections may be any as long as the projections can perform positioning and supporting functions, and the number is one, two, three, four, etc. Various shapes are conceivable, and various cross-sectional shapes are conceivable, such as a steel plate bent into a U-shape, an L-shape, a non-bent shape, a rectangular shape, and the like. Various types of joining between the load receiving member and the supporting member such as welding joining and bolting joining can be considered.

According to a second aspect of the present invention, in the case of the first aspect, the supporting member and the load receiving member are formed of a plate bending material obtained by bending a steel plate to have a plurality of sides. The protrusion of the load receiving member is positioned along the side of the support member, and a punch and a die for connecting the support member and the load receiving member to the side and the protrusion. That is, the used caulked joint is formed.

According to the present invention, since the projection of the load receiving member is positioned along the side of the support member and these are joined by caulking using a punch and a die, the load receiving member and the support are joined together. The joining with the member can be performed in a short time without increasing the cost compared to the welding joining or the bolting joining. For crimping, it is only necessary to have relatively simple equipment that presses the punch to the die side, and it does not require much equipment cost, and it requires less labor than welding or bolting, so it is joined by caulking Costs can be reduced. Of course, the strength of the caulked joint is not inferior to that of the welded joint. In addition, since the load receiving member and the supporting member are formed of a plate bending material obtained by bending a steel plate, a projection can be easily formed on the load receiving member side, and the projection is formed on the side of the supporting member. It is easy to follow along.

According to a third aspect of the present invention, in the case of the second aspect, a horizontal base locking portion of a support member suspended from a building base and an end portion of the base locking portion are provided. And a suspension part extending obliquely downward from the base plate is formed by bending one steel plate, and a fixing part on the base locking part side is positioned along a side part on the suspension part side, and this fixing part and the suspension part side Is formed with a caulked joint similar to the caulked joint.

In the present invention, even if the support member is of a suspension type having a base locking portion and a suspension portion having different directions, these are formed by bending a single steel plate. Compared to the case of forming from steel plate,
The positioning between the base locking part and the suspension part becomes unnecessary, and the fixing part on the base locking part side is positioned along the side part on the suspension part side during bending, and the fixed part and the side part are punched. Since the base and the die are crimped together, the connection between the base locking portion and the suspension portion can be performed in a short time without increasing the cost.

According to a fourth aspect of the present invention, in the case of the third aspect, the hole of the support member is formed closer to the load receiving member than the position of the fixing portion.
The fixing portion is positioned so as to overlap the upper end surface side of the protrusion of the load receiving member inserted into the hole.

According to the present invention, when a downward load is applied to the central portion of the load receiving member, an upward force or moment is applied to the projection projecting toward the support member through the hole.
These forces and moments are transmitted to the support member side not only through the joint between the load receiving member and the support member but also through the fixing portion. Therefore, in this support gantry, the periphery of the joint between the load receiving member and the support member can be reinforced by the fixing portion, and the structure can be made correspondingly firm.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show the lower side of a bathroom unit provided with a support base according to an embodiment of the present invention.

In addition, on the lower surface side of the floor pan 2, a reinforcing rib 2a is formed, and mounting portions 2b and 2c to be mounted on the support base 1 are formed. Also,
Reference numeral 6 in FIGS. 1 and 2 denotes a drain trap attached to the lower surface of the floor pan 2.

As shown in FIGS. 1 and 2, the support base 1 has a pair of support members 20 which are fixed to the base D at both ends of a horizontal load receiving member 10 on which the floor pan 2 is placed. Are mounted in an inverted (C) shape, and transmit the load of the bathroom unit to the base D side. The support base 1 has a load receiving member 1 on the upper side of the support member 20.
0, a support base 1A on the washing place A side of the floor pan 2, and a support base 1B on the bathtub 4 side of the floor pan 2, in which the load receiving member 10 is mounted below the support member 20. There are two types of support bases 1A and 1B,
There is no difference in the structure due to the difference in the position of the load receiving member 10.

As shown in FIG. 3 and FIG. 6, the load receiving member 10 is formed by bending a steel plate symmetrically so as to have a plurality of sides. This load receiving member 10
Is formed in such a manner that a cross section composed of an upper side portion 11 and left and right side portions 12 and 12 has a U-shape, but a horizontal reinforcing side portion 13 protrudes outward at a lower end of the side portions 12 and 12. At both ends, a pair of projections 14, 14 both for positioning and for load support, are formed so as to extend from the end face T side serving as the insertion restricting portion to the side portions 12, 12. Have been.

The support member 20, as shown in FIG.
It is composed of a horizontal base locking portion K1 supported on the base D, and a suspension portion K2 for attaching the load receiving member 10 that extends diagonally downward from one end of the base locking portion K1. The steel plate is formed from a plate bending material obtained by bending a steel plate symmetrically so as to have a plurality of sides.

As shown in FIG. 6, the base locking portion K1 has a cross section composed of an upper side portion 21 and left and right side portions 22, 22, and has a U-shaped cross section. In addition, the mounting side portion 23 on the base D is formed horizontally so as to protrude outward, and the pair of fixing portions 24, 24 is formed so as to protrude from the side portions 22, 22 to the suspension portion K2 side. It was done. As shown in FIG. 3, a screw hole 21a into which the level adjustment bolt B1 is screwed is formed in the upper side portion 21, and a screw B2 for fixing to the base D is formed in the mounting side portion 23. Screw hole 2 to be inserted
3a are formed. Note that the size between the side portions 22 is substantially the same as the size between the side portions 12 of the load receiving member 10.

As shown in FIG. 6, the suspension portion K2 has side portions 25, 25, an upper side portion 26, and reinforcing side portions 27, 27, and has a cross section similar to that of the base locking portion K1. Although the gap between the side portions 25, 25 is formed larger than that of the base locking portion K1 by two sheet thicknesses, the base is formed on the inner surface side of the side portions 25, 25. The fixing portions 24, 24 of the locking portion K1 are positioned so as to be along. Then, on the side of the load receiving member 10 of the side portions 25, 25, the side portion 2
A pair of vertically elongated holes 26a, 26a into which the projections 14 of the load receiving member 10 are inserted are formed on both sides of the upper side 26 formed so as to connect the upper and lower parts 5, 25. Then, the projections 14 of the load receiving member 10 inserted into the holes 26a, 26a are positioned along the inner surfaces of the side portions 25, 25.

In the support base 1A, since the hole 26a is formed directly below the fixing portion 24 of the base locking portion K1,
The protrusion 14 of the load receiving member 10 inserted into the hole 26 a is positioned such that the upper end surface thereof is in contact with the lower end side of the fixing portion 24.

Next, the procedure for manufacturing the support base 1 will be described. First, as shown in FIGS. 4A and 4B, in order to form the load receiving member 10 and the support member 20, for example, a load obtained by cutting a galvanized steel sheet having a thickness of 2.3 mm into a predetermined shape. A stripping body M1 for the receiving member 10,
A stripping body M2 for the support member 20 is formed by cutting a 3.2 mm-thick galvanized steel sheet into a predetermined shape. In this case, the end surface T of the side portion 12 and the reinforcing side portion 13 of the strip body M1
The tip 14a of the projection 14 is cut obliquely in accordance with the inclination of the suspension K2 of the support member 20. In addition,
Steel plate cutting is a shearing machine (shearing machine)
And punching is performed with a press.

Next, the load receiving member 10 is formed by bending the plate body M1 using a roll forming machine. Also, as shown in FIG. 5, after forming the preformed body N by press bending the stripping body M2, as shown in FIG. 6, the upper side part 21 is bent by a predetermined angle to form the base locking part K1. Suspension K
And 2. Then, a screw hole 21a is formed using a tap or the like in the press bent portion, and the fixing portions 24, 24 of the base locking portion K1 and the side portions 2 of the suspension portion K2 are formed.
5 and 25 are firmly connected by caulking to form the support member 20. The load receiving member 10 includes
A cushioning material (foamed polyethylene plate) on which the placing portions 2b and 2c of the floor pan 2 are placed is attached.

Next, as shown in FIGS. 8A and 8B, the projection 14 of the load receiving member 10 is moved until the end face T of the load receiving member 10 abuts against the upper side 26 of the support member 20. The support member 20 is inserted into the hole 26a of the support member 20 to position the load receiving member 10 and the support member 20. Subsequently, in a state where the load receiving member 10 is pressed toward the support member 20, the protrusions 14 and 14 of the load
As shown in FIG. 8 (c), the supporting frame 1A is completed by connecting the side portions 25, 25 of the “0” by caulking as shown in FIG.

By the way, caulking is known as, for example, TOX bonding. As shown in FIG. 7, after two steel plates L1 and L2 are placed on a die Y, a punch P is moved toward the die Y. By moving, two steel plates L
The two steel plates L1 and L2 are caulked and joined by forming a caulked joint S on one of the outer surfaces of the steel plates L1 and L2 with a concave portion U1 and a convex portion U2 on the other outer surface. In the recess Y1 of the die Y, a small protrusion Y2 is formed on the bottom side, and a ring-shaped groove Y3 is formed around the small protrusion Y2.
Is formed, the protrusion P1 of the punch P causes 2
When a part of the steel plates L1 and L2 is pushed into the recess Y1 of the die Y, a part Q of the steel plate L1 on the punch P side escapes to the steel plate L2 side on the die Y side, and the two steel plates L1 and L2 Caulked.

In this embodiment, the size of the concave portion U1 of the caulked joint S is, for example, 6 mm in diameter and 6 m in depth.
m, the size of the protrusion U2 is 12 mm in diameter and 3 mm in height, and the recess U1 is formed so as to face the outer surface side of the support member 20.

Next, the operation and effect of the support base 1 will be described. In this support gantry 1, until the end face T abuts against the support member 20 at the end of the load receiving member 10.
Since the positioning and supporting protrusions 14 to be inserted into the holes 26a of the support member 20 are formed, the load receiving member 10 is moved toward the support member 20 when the load receiving member 10 and the support member 20 are joined. Only by pressing, the position between the load receiving member 10 and the support member 20 can be determined. For this reason, a complicated jig is not required for positioning the load receiving member 10 and the support member 20, and the cost of the jig can be reduced accordingly, and the positioning of these members 10, 20 can be shortened. This can be easily performed in a short time, and the number of man-hours for manufacturing the support base 1 can be reduced.

In this case, the projection 14 has a size enough to withstand the load acting on the load receiving member 10 and is supported by the support member 20 through the hole 26a. Even if the caulked joint S between the receiving member 10 and the support member 20 has a poor connection or the like, and the load receiving member 10 and the support member 20 are not sufficiently joined by the caulked joint S, the load receiving member 10 is supported. It does not move from the member 20 side and come off. Therefore, by using this support base 1, the safety of the bathroom unit can be enhanced.

Further, in the support gantry 1, the projections 14 of the load receiving member 10 are positioned along the side portions 25 of the support member 20, and these are joined by caulking using a punch P and a die Y. Because of the joining, the joining between the load receiving member 10 and the support member 20 can be performed in a short time at a lower cost than welding joining or bolting joining. For crimping, it is sufficient if there is a relatively simple equipment that only presses the punch P to the die Y side, and the equipment cost is not so much. By doing so, the cost can be reduced.

By the way, the strength of the caulked joint S is not inferior to that of the welded joint or the bolted joint, and the caulked joint does not require any labor for the operation. The quality of the joint can be improved. In addition, since caulking does not use heat as compared to welding, even if steel plates are plated for rust prevention (for example, zinc plating), this plating does not come off at the time of joining, There is no need to apply a rust inhibitor to the joint as in the case of welding.

Since the load receiving member 10 and the support member 20 are formed by bending a steel plate cut into a predetermined shape, the projections 14 can be easily formed on the load receiving member 10. The protrusion 14 can be easily positioned along the side 25 of the support member 20.

Further, in the support base 1, the support member 2
Since the base locking portion K1 and the suspension portion K2 are formed by bending one steel plate, the base locking portion K1 and the suspension portion K2 are compared with a case where they are formed from separate steel plates.
This eliminates the need for positioning, and accordingly, the number of manufacturing steps for the support member 20 can be reduced. At the time of bending, the fixing portion 24 on the base locking portion K1 side is replaced with the side portion 22 on the suspension portion K2 side.
And the fixed portion 24 and the side portion 22 are caulked and joined using the punch P and the die Y. Therefore, the reinforcing joint between the base locking portion K1 and the suspension portion K2 is also required. It can be done in a short period of time without much cost.

In the support frame 1A of the support frame 1 which is disposed on the washing pan A side of the floor pan 2, the fixing portion 24 of the support member 20 is provided on the upper end surface side of the projection 14 of the load receiving member 10. Since they are positioned so as to overlap with each other, a downward load is applied to the upper side 11 of the load receiving member 10 by the floor pan 2 or the like, and an upward force is applied to the protrusion 14 projecting toward the support member 20 via the hole 26a. Even if a moment or a moment acts, these forces and the like are transmitted not only to the caulked joint portion S but also to the support member 20 side via the fixing portion 24. For this reason, in the support base 1A, the periphery of the caulked joint portion S can be reinforced by the fixing portion 24 of the support member 20, and the structure can be made correspondingly firm.

The size, number, and shape of the projections 14 of the load receiving member 10 may be any as long as they can withstand the force acting on the load receiving member 10 side. However,
In the case where the load receiving member 10 and the support member 20 are connected by caulking, the protrusion 14 needs to be large enough to be caulked. Of course, the same is required for the fixing portion 24 of the support member 20 to be crimped.

The hole 26a of the support member 20 into which the projection 14 of the load receiving member 10 is inserted is as close as possible to the cross-sectional shape of the projection 14 so that the end of the load receiving member 10 can be positioned sufficiently. It is better to form it. Further, the insertion restricting portion of the projection 14 may be formed by bending a steel plate.

Further, in this embodiment, two caulking joints S are formed for each one protruding portion 14 and fixing portion 24. However, the present invention is not limited to this. May be formed in a number that can be sufficiently joined. Of course, the size of the caulked joint S (the size of the protrusion P1 of the punch P and the size of the recess Y1 of the die Y) can also be freely changed.

Further, the connection between the load receiving member 10 and the support member 20 and the base locking portion K1 and the suspension portion K2 of the support member 20 are provided.
May be welded joints or bolted joints.

Further, in this embodiment, the support base 1
Is a suspension type that is suspended on the base D.
As shown in FIG. 1, the support members 20 attached to both sides of the load receiving member 10 are mounted on the installation surface F of the bathroom unit (FIG. 1).
(See Reference). In this case, a level adjusting bolt B is provided on the lower side of the support member 20.
It is necessary to form one support portion K3.
3 is not manufactured as a separate member, but the entire support member 20 is integrally formed from a single steel plate by plate bending and caulking as in the case of the base locking portion K1 with respect to the suspension portion K2. Is also good.

Further, in this embodiment, the support base 1 of the bathroom unit has been described as an example.
May be used in another unit room (assembled room) installed in a building, such as a shower room unit, a dressing room unit, a washroom unit, and a toilet unit.
