Description

  Aspects of the present invention generally relate to a suspension platform and a method for manufacturing the same.

  There is known a suspension stand that is bridged and fixed between the bases of a building frame and supports an equipment unit such as a bathroom unit (for example, Patent Document 1). The suspension mount includes a pair of suspension fittings that are fixed to a base such as a large pull or a floor beam, and a mount that is spanned between the suspension fittings. As described above, since the hanging metal fitting and the gantry are configured separately, it is necessary to assemble the hanging metal fitting and the gantry.

JP 2006-112510 A

  As a means for reducing the time and labor of assembly, it is conceivable to bend the both ends of the suspension base so as to provide the function of the suspension bracket and eliminate the suspension bracket. That is, it is conceivable that the hanging metal fitting and the gantry are configured integrally. In this case, at least one end of the suspension base needs to be thin because it is inserted through a narrow gap that is vacant between the base and the bathroom unit. However, if it is made thinner than the longitudinal direction of the suspension base, the strength in the longitudinal direction is weakened, and the floor surface of the bathroom unit (for example, a washing place) may be shaken or submerged in the longitudinal direction.

  The present invention has been made on the basis of recognition of such a problem, and provides a suspension frame in which the strength in the longitudinal direction is improved in a suspension frame in which a hanging bracket and a frame are integrally formed, and a manufacturing method thereof. With the goal.

  A first aspect of the present invention is a suspension base for supporting an equipment unit that is bridged between the foundations of a building frame, the support part supporting the equipment unit, provided at both ends of the support part, and the support Each of the pair of fixing portions is formed integrally with the support portion, and is formed in a central region of the support portion. Is a cylinder having a rectangular cross section, and includes an upper plate, a lower plate, a first side plate, and a second side plate, and at least one of the pair of fixing portions includes an upper surface portion and a lower surface. A folding region having a portion, a first bent portion, and a second bent portion, wherein the first bent portion has one end in the width direction of the upper surface portion and one end in the width direction of the lower surface portion, The second bent portion, the other end in the width direction of the upper surface portion, the other end in the width direction of the lower surface portion, The first bent portion and the second bent portion are bent inwardly so as to approach each other, the upper surface portion extends so as to continue from the upper plate, and the lower surface portion is Extending from the lower plate, the first bent portion extends from the first side plate, the second bent portion extends from the second side plate, and the reinforcing member includes the folding member. The suspension base is provided between the upper surface portion and the lower surface portion of a region.

  According to this suspension mount, in the suspension mount in which the support portion (mounting stand) and the pair of fixing portions (hanging brackets) are integrally formed, a folding region is formed to make the end region (fixed portion) of the suspension stand thin. In addition, the strength in the longitudinal direction of the suspension base can be improved by providing the reinforcing material in the folding region. That is, since the reinforcing material is inserted in the fixing portion, the side plates of the square pipe are bent so as to approach each other so as to integrally form the support portion and the pair of fixing portions, and the longitudinal direction of the fixing portion of the suspension base is Even when the thickness is reduced, the strength can be secured in the longitudinal direction of the suspension base. Therefore, rolling and sinking of the floor surface of the washing place can be suppressed. In addition, since it is not necessary to add a reinforcing material in an environment with poor scaffolding such as a construction site, the workability is excellent.

  According to a second invention, in the first invention, the reinforcing member is provided in a portion of the folding region where the upper surface portion is bent.

  According to this suspension stand, since the reinforcing material is provided at the bent portion where particularly high strength is required in order to suppress the rolling and sinking of the floor surface of the washing place, the floor surface may be shaken or sinked in the longitudinal direction. It is possible to suppress dripping firmly.

  A third invention is the suspension stand according to the first or second invention, wherein the reinforcing material is provided continuously from one end to the other end in the longitudinal direction of the folding region.

  According to this suspension stand, since the reinforcing material is continuously provided in the entire longitudinal direction of the folding region, it is possible to firmly suppress the floor surface from shaking or sinking in the longitudinal direction.

  4th invention is the manufacturing method of the suspension stand for spanning between the bases of a building frame, and supporting an equipment unit, Comprising: In at least one of the both ends of the metal square pipe which has a rectangular cross section Bending the pair of side plates inwardly so that the pair of opposite side plates of the square pipe approach each other to form a folding region; and forming both ends at the center of the square pipe Forming a support part for supporting the equipment unit from the central part by bending the part at a substantially right angle to the part, and forming a pair of fixing parts fixed to the base from the both end parts. In the step of forming the folding region, a reinforcing material is inserted into a position that becomes the folding region inside the square pipe.

  According to this method for manufacturing a suspension base, in a suspension base in which a support portion (mounting base) and a pair of fixing portions (suspension brackets) are integrally formed, a folding region is formed to form an end region (fixing portion) of the suspension base. In addition, the strength in the longitudinal direction of the suspension base can be improved by providing a reinforcing material in the folding region. That is, since the reinforcing material is inserted in the fixing portion, the side plates of the square pipe are bent so as to approach each other so as to integrally form the support portion and the pair of fixing portions, and the longitudinal direction of the fixing portion of the suspension base is Even when the thickness is reduced, the strength can be secured in the longitudinal direction of the suspension base. Therefore, rolling and sinking of the floor surface of the washing place can be suppressed.

  According to the aspect of the present invention, there is provided a suspension base in which the strength in the longitudinal direction is improved and a method for manufacturing the same in the suspension base in which the suspension metal fitting and the base are configured integrally.

As shown in FIG. 5, the central region 10a has a cylindrical shape having a rectangular cross section. In other words, the central region 10a has a square pipe shape. The central region 10 a includes a first side plate 21, a second side plate 22, an upper plate 23, and a lower plate 24. The central region 12 b of the support portion 12 is configured by the central region 10 a of the suspension base 10. Accordingly, the central region 12 b of the support portion 12 has a cylindrical shape having a rectangular cross section, and includes the first side plate 21, the second side plate 22, the upper plate 23, and the lower plate 24.

  The upper plate 23 faces the lower plate 24. The upper plate 23 and the lower plate 24 have a horizontal plate shape. The upper plate 23 and the lower plate 24 are parallel flat plates arranged horizontally. The upper plate 23 and the lower plate 24 may have an inclination of an error level. “Horizontal” is, for example, a state in which the inclination in each direction is ± 2 ° or less when the complete horizontal is the reference (0 °). The upper plate 23 forms the upper surface 12a of the support part 12, for example. The saucer 16 is fixed to the upper plate 23.

  The first side plate 21 extends in the vertical direction and connects one end of the upper plate 23 in the width direction and one end of the lower plate 24 in the width direction. The second side plate 22 extends in the vertical direction and connects the other end of the upper plate 23 in the width direction and the other end of the lower plate 24 in the width direction.

  The lengths of the first side plate 21 and the second side plate 22 in the vertical direction are substantially the same as the lengths of the upper plate 23 and the lower plate 24 in the width direction. That is, the cross-sectional shape of the central region 10a is a square shape. The lengths of the first side plate 21 and the second side plate 22 in the vertical direction may be shorter than the lengths of the upper plate 23 and the lower plate 24 in the width direction, for example.

FIG. 6 is a cross-sectional view illustrating a part of the suspension base according to the embodiment.
6 represents a cross section taken along line B1-B2 of FIG.
As shown in FIG. 6, each end region 10 b has a folding region 30. The folding region 30 includes a first bent portion 31, a second bent portion 32, an upper surface portion 33, and a lower surface portion 34. A pair of fixing | fixed part 14 is comprised by the two edge area | regions 10b. Accordingly, each fixing portion 14 has a folding region 30 having a first bent portion 31, a second bent portion 32, an upper surface portion 33, and a lower surface portion 34. The upper surface portion 33 faces the lower surface portion 34. The first bent portion 31 connects one end of the upper surface portion 33 in the width direction and one end of the lower surface portion 34 in the width direction. The second bent portion 32 connects the other end of the upper surface portion 33 in the width direction and the other end of the lower surface portion 34 in the width direction. The first bent portion 31 and the second bent portion 32 bend in a convex shape inward so as to approach each other.

  A metal reinforcing material 70 is provided in the folding region 30. The reinforcing member 70 is provided between the upper surface portion 33 and the lower surface portion 34 of the folding region 30. That is, the reinforcing member 70 is provided inside the folding region 30. In this example, the reinforcing member 70 is provided between the first bent portion 31 and the second bent portion 32 and the lower surface portion 34. The reinforcing material 70 may be provided between the first bent portion 31 and the second bent portion 32 and the upper surface portion 33. The reinforcing member 70 is provided both between the first bent portion 31 and the second bent portion 32 and the lower surface portion 34 and between the first bent portion 31 and the second bent portion 32 and the upper surface portion 33. Also good.

  For the reinforcing material 70, for example, a metal material such as iron, stainless steel, or aluminum is used. The reinforcing material 70 has, for example, a plate shape. The length of the reinforcing member 70 in the width direction is shorter than the length of the upper surface portion 33 or the lower surface portion 34 in the width direction, for example. A plurality of reinforcing members 70 may be provided in the width direction. The reinforcing material 70 may have a shape other than a plate shape, for example, a rod shape.

  As shown in FIG. 6, in this example, the folding region 30 is provided with a bead whose height in the vicinity of the center in the width direction is higher than the heights at both ends in the width direction. By providing such a bead, the strength in the longitudinal direction of the folding region 30 can be further improved. The height H1 of the bead is, for example, not less than 0.5 mm and not more than 10 mm. For example, the bead is provided in the arm portion 14a and the engaging portion 14b. The bead may be provided only in one of the arm portion 14a and the engaging portion 14b. The bead may be provided on the entire arm portion 14a and the engaging portion 14b, or may be provided on a part of the arm portion 14a and the engaging portion 14b. The beads are provided as necessary and can be omitted.

FIG. 7 is a partial cross-sectional view illustrating an example of a usage state of the suspension frame according to the embodiment.
FIG. 7 shows a cross section taken along line C1-C2 of FIG.
As shown in FIG. 7, each of the fixed portions 14 is formed integrally with the support portion 12. In other words, each of the fixed portions 14 is continuous with the support portion 12. Similarly, each of the end regions 10b is continuous with the central region 10a. The upper surface portion 33 extends so as to continue from the upper plate 23. The lower surface portion 34 extends from the lower plate 24. The first bent portion 31 extends from the first side plate 21. The second bent portion 32 extends so as to continue from the second side plate 22.

  Each fixing portion 14 is formed by bending both end portions of the support portion 12. When the first side plate 21 and the second side plate 22 are bent to form the first bent portion 31 and the second bent portion 32, the vertical lengths of the first side plate 21 and the second side plate 22 are the upper plate 23 and If it is longer than the length of the lower plate 24 in the width direction, the first bent portion 31 and the second bent portion 32 are difficult to form, for example, a portion that overlaps the first bent portion 31 and the second bent portion 32 is generated. turn into. Therefore, as described above, the vertical lengths of the first side plate 21 and the second side plate 22 are preferably equal to or shorter than the lengths of the upper plate 23 and the lower plate 24 in the width direction.

  As shown in FIG. 7, the arm portion 14 a of each fixing portion 14 needs to be inserted through a gap CL that is vacant between the base 2 and the bathroom unit 4. At this time, the gap CL is relatively narrow. The gap CL is, for example, not less than 2 cm and not more than 10 cm. Therefore, it is preferable that the thickness of each fixing portion 14 (the length in the direction perpendicular to the upper surface and the lower surface) be as thin as possible. The thickness T2 (see FIG. 6) of each fixing portion 14 is, for example, less than half the thickness T1 (see FIG. 5) of the support portion 12. In other words, the thickness of each end region 10b is less than or equal to half the thickness of the central region 10a. Thereby, the fall of the intensity | strength of each fixing | fixed part 14 can be suppressed, suppressing the thickness of each fixing | fixed part 14 appropriately. Further, the gap CL can be narrowed. The thickness T1 of the support part 12 is 3 cm or more and 20 cm or less, for example. The thickness T2 of each fixing portion 14 is, for example, not less than 0.5 cm and not more than 2 cm.

  As shown in FIG. 7, the reinforcing member 70 is continuously provided from one end to the other end in the longitudinal direction of the folding region 30. Thus, by providing the reinforcing material 70 continuously in the entire longitudinal direction of the folding region 30, the reinforcing material 70 is provided only in a part of the folding region 30, or the reinforcing material 70 is provided intermittently. In comparison, the strength of the suspension base 10 in the longitudinal direction can be further improved, and the deflection of the suspension base 10 can be suppressed. A plurality of reinforcing members 70 may be provided in the thickness direction. In this case, the total thickness of the plurality of reinforcing members 70 is regarded as the thickness T3 of the reinforcing member 70 (see FIG. 6).

Fig.8 (a)-FIG.8 (d) are explanatory drawings showing an example of the manufacturing process of the suspension stand which concerns on embodiment.
As shown in FIGS. 8A to 8D, for example, a metal square pipe 100 having a rectangular cross section and a reinforcing material 70 are used for manufacturing the suspension base 10. 8A and 8C show a state in which the end portion 100a of the square pipe 100 is viewed from the width direction side. FIGS. 8B and 8D show a state in which the end portion 100a of the square pipe 100 is viewed from the longitudinal direction side.

  In manufacturing the suspension base 10, first, as shown in FIGS. 8A to 8D, the opposing pair of side plates 121 and 122 approach each other at both ends 100 a of the square pipe 100. The pair of side plates 121 and 122 are bent inwardly to form a folded region 30. At this time, a metal reinforcing material 70 is inserted (inserted) into the square pipe 100 at a position to be the internal folding region 30.

  For example, as shown in FIG. 8B, the vicinity of the center in the vertical direction of the side plates 121 and 122 is pressed inward from the outside. At the same time, the upper plate 123 of the end portion 100a is pressed downward with a substantially equal force in the left-right direction, and the lower plate 124 of the end portion 100a is pressed upward with a substantially equal force in the left-right direction. In other words, the end portion 100a is pressed in the vertical direction while applying force to the end portion 100a from both sides to fold the side plates 121 and 122 inward. As a result, as shown in FIGS. 8C and 8D, the end portion 100a of the square pipe 100 can be crushed with the side plates 121 and 122 bent. Further, the reinforcing material 70 can be sandwiched between the upper surface portion 33 and the lower surface portion 34 of the folding region 30. At this time, the thickness of both end portions 100a of the square pipe 100 is, for example, less than half the thickness of the central portion 100b of the square pipe 100. Thereby, the center area | region 10a is formed from the center part 100b, and each end area | region 10b is formed from the both ends 100a.

  After that, by bending both end portions 100a upward (substantially at right angles) to the central portion 100b of the square pipe 100, the support portion 12 is formed from the central portion 100b, and each fixing portion 14 is formed from both end portions 100a ( (See FIG. 7). More specifically, both end portions 100a are bent upward at a substantially right angle to form an arm portion 14a, and a part of the arm portion 14a located on the opposite side to the central portion 100b is further bent in the horizontal direction. The engaging portion 14b is formed. Then, the tray 16 is fixed to the upper surface 12a (upper plate 23) of the support part 12 as needed. Thereby, the suspension frame 10 is manufactured from the square pipe 100 and the reinforcing material 70. A substantially right angle refers to a range of 85 ° to 95 °.

  The step of bending the side plates 121 and 122 may be performed by bending the side plates 121 and 122 at one end 100a of the square pipe 100 and then bending the side plates 121 and 122 at the other end 100a. Alternatively, the side plates 121 and 122 may be bent substantially simultaneously at both ends 100a of the square pipe 100.

  The step of bending both end portions 100a at a substantially right angle may be performed by bending one end portion 100a of the square pipe 100 and then bending the other end portion 100a, or by bending both end portions 100a substantially simultaneously. Good. For example, the step of bending both end portions 100a at a substantially right angle by pressing using a mold or the like may be performed substantially simultaneously with the step of bending the side plates 121 and 122.

  When providing the above beads, for example, after forming the arm portion 14a and the engaging portion 14b, the bead is provided on the arm portion 14a and the engaging portion 14b by pressing.

  As described above, according to the suspension base 10 and the manufacturing method thereof according to the present embodiment, the folding region 30 is formed in the suspension base 10 in which the support portion 12 and the pair of fixing portions 14 are integrally formed. The strength of the suspension base 10 in the longitudinal direction can be improved by making the end region 10 b (fixing portion 14) of the suspension base 10 thin and providing the metal reinforcing material 70 in the folding region 30. That is, since the metal reinforcing material 70 is inserted into the fixed portion 14, the side plates 121 and 122 of the square pipe 100 are brought close to each other so that the support portion 12 and the pair of fixed portions 14 are integrally formed. Even when it is bent and the thickness of the fixed portion 14 of the suspension base 10 is reduced in the longitudinal direction, the strength can be ensured in the longitudinal direction of the suspension base 10. Therefore, rolling and sinking of the floor surface of the washing place can be suppressed. In addition, since it is not necessary to add a reinforcing material in an environment with poor scaffolding such as a construction site, the workability is excellent.

  In addition, according to the suspension base 10 and the manufacturing method thereof according to the present embodiment, the support portion 12 and the pair of fixing portions 14 are integrally configured. Thus, the suspension base 10 can be manufactured more easily. Further, the upper surface portion 33, the lower surface portion 34, the first bent portion 31, and the second bent portion 32 of the two end regions 10b are respectively connected to the upper plate 23, the lower plate 24, the first side plate 21, and the central region 10a. The second side plate 22 extends in a continuous manner. For this reason, for example, when using the metal square pipe 100 with high rigidity in the manufacture of the suspension base 10, the suspension base 10 can be manufactured simply by bending and processing both ends 100a of the square pipe 100. . Therefore, the suspension base 10 can be manufactured more easily than the case where the suspension base is manufactured by combining the square pipe 100 and another member. Moreover, member cost can be reduced rather than the case where a suspension stand is manufactured combining the square pipe 100 and another member.

  Furthermore, since the first bent portion 31 and the second bent portion 32 of the end region 10b are bent inwardly so as to approach each other, the strength of the suspension base 10 is increased while suppressing the thickness. Can be given. For example, when the construction worker rests on the support portion 12 and moves, the suspension base 10 can be made more difficult to deform with respect to the twist acting on the suspension base 10.

  For example, the first bent portion 31 and the second bent portion 32 may be bent outwardly so as to be separated from each other. In this case, it must be pressed from the inside to the outside of the square pipe 100, which makes manufacturing difficult. For example, it becomes difficult to manage the dimensions of the first bent portion 31 and the second bent portion 32. Further, when bent outward, the thickness becomes thinner by the amount of the first bent portion 31 and the second bent portion 32 than when bent inward, and the strength of the end region 10b is reduced. Resulting in. As described above, when bent inward, the first bent portion 31 and the second bent portion 32 can be manufactured more easily than when bent outward, and the strength of the end region 10b is increased. Can be further improved.

  Moreover, in the suspension stand 10, the thickness of the two end regions 10b is less than or equal to half the thickness of the central region 10a. Thereby, it is possible to give the end region 10b higher strength while appropriately suppressing the thickness of the end region 10b.

FIG. 9 is a cross-sectional view illustrating a part of a modified example of the suspension base according to the embodiment.
FIG. 6 shows a state where there is substantially no gap inside the end region 10b. Without being limited thereto, as illustrated in FIG. 9, the end region 10 b may have a gap AG <b> 1 between the first bent portion 31 and the upper surface portion 33. The end region 10 b may have a gap AG <b> 2 between the first bent portion 31, the lower surface portion 34, and the reinforcing material 70.
