EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the metal box which concerns on this invention, a metal arrangement | positioning, and the support apparatus of a metal box is demonstrated based on drawing.
(First embodiment)

  1 to 12 show a first embodiment of the present invention. Reference numeral B in the figure is a metal box, for example, embedded in a concrete wall so that the opening faces the front side of the wall, and accommodates a switch, an outlet or the like installed on the wall.

  This metal box B includes a cylindrical peripheral wall 1, an opening 3 surrounded by the peripheral wall on one end side of the peripheral wall, and a bottom wall 2 facing the opening and closing the other end side of the peripheral wall. It is formed in a bottomed box shape. The peripheral wall 1 and the bottom wall 2 are formed in a state of being closed by a removable cover plate N1, and an introduction port N through which a cable or electric wire can be introduced into the metal box by being removed. Several are arranged. The cables introduced from the introduction port N are connected to each other inside the box or connected to a wiring device accommodated inside.

  Specifically, it consists of a square plate-like bottom wall 2 and a square cylindrical peripheral wall 1 (1a, 1b, 1c, 1d) standing from the bottom wall, and a single metal plate is formed by drawing with a press. A square-bottomed box-like metal wiring box is formed, and an inner space is formed on the inner side surrounded by the bottom wall 2 and the peripheral wall 1 to accommodate wiring devices, cable connection portions, and the like. Is provided facing the bottom wall 2. The bottom wall 2 is formed with five holes that pass through without being blocked, and screw holes 21 into which screws for ground wiring are screwed, and a fixing tool for fixing a metal wiring box are attached. And four fixing holes 22 (which are generally attached using two of the four, depending on the form of the fixture). Further, at the center of the four fixing holes, when the metal wiring box is embedded in the concrete, there is a screwed portion 23 for screwing a bolt penetrating the concrete mold and pulling it toward the mold. Is provided. These five holes (screw holes 21, four fixing holes 22) and screwed portions 23 are generally sold in a state in which all of them are closed by a closing tape 24 (a chain line in the figure).

  Among the opposing peripheral walls (1a and 1c or 1b and 1d), the box cover mounting pieces 11 are respectively directed to the opposing peripheral walls on the inner side of the peripheral wall at the open end of the pair of peripheral walls (1b and 1d). It is bent. The outer surface on the opening direction side of the mounting piece 11 is positioned substantially on the same plane as the opening end surface without protruding toward the opening direction. Moreover, the partition plate holding | maintenance part 12 which hold | maintains the partition plate which partitions off the inside of a metal wiring box is provided inside one pair of surrounding walls (1b and 1d) which have the said attachment piece, respectively. The partition plate holding portion 12 is composed of a pair of holding pieces which are bent inward from the opening end and further turned back toward the bottom wall 2. The space between the holding pieces is substantially the same as the thickness of the partition plate. By inserting the partition plate between the pair of holding pieces through the opening, one side of the peripheral wall is as if standing from the bottom wall. Both ends are held by both partition plate holding portions provided in the pair, and the inside of the box can be partitioned (in the illustrated metal wiring box, the inside is divided into two). Each holding piece of the partition plate holding portion is also positioned on the substantially same plane as the opening end face without projecting toward the opening direction side, as in the case of the mounting piece. 6).

  And the peripheral wall (1a and 1c) of the other pair (the side on which the mounting piece and the partition plate holding part are not provided) of the opposing peripheral walls is located outside the peripheral wall between the introduction port N and the open end. A cut-and-raised portion 4 cut and raised is provided, and the cut-and-raised portion 4 is provided with an attachment portion 41 for attaching a support member S that supports the metal wiring box. The cut-and-raised part 4 is provided at a total of four locations, two on each of the other pair of peripheral walls (1a and 1c). (In other words, a total of four places are provided on two opposing walls of the peripheral wall of the square cylindrical shape, respectively.) These cut-and-raised parts 4 are for attaching the support member with two places as one set. The two support members are attached to the respective walls by a total of two sets of cut and raised portions (4a and 4b and 4c and 4d) provided on the other pair of peripheral walls.

  More specifically, the cut-and-raised portion 4 is a part of the peripheral wall in the vicinity of the opening end of the peripheral wall that has been cut and raised so that the central portion bulges outward from the peripheral wall with both ends connected to the peripheral wall. It is formed by cutting up and forming into a belt shape. A through hole 42 through which the support member S is inserted is formed between the cut and raised inner surface and the outer peripheral surface of the peripheral wall (on both sides of the cut and raised portion), and the attachment portion 41 to which the support member S can be attached is formed. It is composed. As shown in FIG. 11, the support member S used here is made of a metal columnar bar material S1, and more specifically, is crushed to a part in the axial direction and bulges outward. A bulging portion S1a is provided. The bar material S1 can be bent in a three-dimensional direction by hand and has a predetermined tensile strength.

  And the two raised portions (4a and 4b and 4c and 4d) provided on the other pair of peripheral walls (1a and 1c), respectively (in other words, two opposite sides of the rectangular cylindrical peripheral wall) The two raised portions provided on each wall) can be inserted into each through hole 42 by linearly moving one bar material S1 formed in a straight line. Each axial center of the through hole 42 formed by the cut and raised portion 4 is located on the same axis. As a result, the bar material inserted into the through hole 42 formed by one cut-and-raised portion is penetrated by the other cut-and-raised portion while the outer surface of the bar material is brought into contact with the inner surface of the cut-and-raised portion and the outer surface of the peripheral wall. It is possible to go straight to the hole 42, and one end is inserted through the through hole 42, and the bar material is moved linearly in the same insertion direction, thereby being smoothly guided while being guided by the inner surface of the cut and raised portion and the outer surface of the peripheral wall. The other through-hole 42 can be passed through. The axis of the bar member inserted through the through hole 42 formed by each cut-and-raised portion 4 is parallel to the outer surface of the peripheral wall (1a or 1c) in which the cut-and-raised portion is formed, and the cut-and-raised portion is formed. It is formed to be parallel to the open end of the peripheral wall.

  The through holes of one of the raised portions (4a and 4d) of the cut and raised portions (4a and 4b and 4c and 4d) of each set (two cut and raised portions provided on the same wall surface) are In the opposite side (bar material insertion side) to the other side cut and raised portion (4b or 4c), a widened receiving port 43 is formed for the bulging portion S1a of the bar material S1 to enter, The taper gradually tapers from the receiving opening 43 toward the other cut-and-raised part (4b or 4d), and finally narrows to such a size that only the shaft of the bar material S1 can pass through. Therefore, the bulging portion S1a that has entered comes into contact with the inner surface of the receiving port and restricts further movement of the bar material in the axial direction. Further, due to the contact between the inner surface of the receiving port and the bulging portion, The rotation of the bar material S1 in the circumferential direction can be prevented. In the present embodiment, the through hole 42 of the other side cut and raised portion (4b or 4c) is formed with a receiving port formed in the one side cut and raised portion (4a or 4d). Instead, a through hole 42 having a size through which only the shaft of the bar material S1 can pass is formed. The receiving port 43 is formed in a size that allows the entire bulging portion S1a to enter (see FIGS. 8 and 9).

  These four cut-and-raised portions 4 are cut and raised from the peripheral wall 1, thereby generating communication points between the outside and the inside of the peripheral wall. In order to close these communication points, it is extended from the opening end of the peripheral wall in the vicinity of each of the raised portions, and is folded back along the inner surface of the peripheral wall so that the base end is the opening end of the peripheral wall and the distal end side faces the bottom wall. A closed piece 5 is provided. The closing pieces 5 are provided in the same number as the cut and raised portions 4 corresponding to the cut and raised portions 4. Specifically, four closing pieces (5a, 5b, 5c, 5d) are provided corresponding to the four raised portions (4a, 4b, 4c, 4d). The whole of the closing pieces does not protrude from the opening end toward the opening direction. Specifically, the outer surface on the opening direction side on the base end side is located on the same plane as the opening end surface, and is folded back along the inner surface of the peripheral wall without protruding to the opening direction side. And the length to the front-end | tip of a closing piece is formed in the length extended to the bottom wall side beyond the communication location produced by the said cut-and-raised part, and the communication location which the said cut-and-raised part 4 produced It is formed in a size that closes the whole.

  The closing piece 5 is folded back during a drawing process by pressing a metal box. Therefore, although the attachment part 41 which attaches the support member S is formed by cutting up, the communication location between the outside and the inside of the peripheral wall that is generated is closed in advance during construction, and the communication location is cured when supported. There is no need to do it. In addition, it does not ask | require whether it turns after making a box shape, or cuts and raises the cut-and-raised part 4 and turns the closing piece 5 and makes it a box shape.

  Next, a procedure for attaching the bar material S1 as the support member S to the metal box B using the attachment portion 41 will be described. First, one end of the bar material S1 is passed through one side of the through hole 4a (an attachment portion provided in the cut and raised portion on the side having the receiving port). The bar material S1 is moved in the axial direction as it is, and one end of the bar material is passed through the through hole 42 on the other side 4b. Then, the bar material bulging portion S1a is entirely inserted into the receiving port 43, and the bulging portion is brought into contact with the inner surface of the receiving port. As a result, the bar material S1 is attached to the metal box B in a state where further movement of the bar material in the axial direction is restricted. The two support members S are attached to the metal box B by performing this operation on each pair of cut and raised portions respectively provided on the other pair of peripheral walls. In this state, as shown in FIG. 12, both end portions of the bar member protruding outward from the one-side through hole and the other side through-hole of each set protrude outward with an equal length. In other words, the bulging portion S1a is provided at a predetermined position in the axial direction of the bar material S1 so that the bulging portion S1a abuts on the inner surface of the receiving port and the movement is restricted, and the bar material S1 protrudes evenly. Yes.

  The metal box B to which the bar material S1 is attached is placed in the concrete form by fixing the bar material S1 to a reinforcing bar or the like embedded in the concrete wall, and is placed in the concrete and placed in the concrete wall. Buried. At this time, it arrange | positions in the said mold so that the said opening end may be press-contacted to a mold by the tension force which the said bar material S1 has. None of the closing piece 5, the box cover mounting piece 11, and the partition plate holding portion 12 protrudes from the opening end toward the opening direction, and does not hinder the entire opening end from being pressed against the mold. .

  When installed in the concrete mold, a conduit may be connected to the inlet N provided in the peripheral wall 1. The bar material S1 exposed between the through holes 42 through which the attached bar material S1 passes does not cross the introduction port N and is along the outer peripheral surface of the peripheral wall. Therefore, even if it is in the state where bar material S1 was attached, inlet N can be used effectively.

  Next, the effect of the metal box B as the metal arrangement A having the above configuration will be described. According to this metal box B, the inside and outside of the metal box produced by cutting and raising a part of the peripheral wall 1 when providing the mounting portion for mounting the support member S (bar material S1). Therefore, after the supporting member S is attached to the attachment portion 41 of the cut and raised portion 4, it is not necessary to cure the communication portion. Further, since the support member S (bar material S1) does not pass through the inside of the peripheral wall and is attached to the outside of the peripheral wall, the internal space is not reduced.

  In addition, since the attachment portion 41 is formed by the through hole 42, it is only necessary to insert the support member S (bar material S1) and against the force in the support member radial direction applied to the support member S (bar material S1). Thus, stable attachment is possible without coming out of the attachment portion 41 in the radial direction.

  Further, by providing the cut-and-raised portion 4 in the vicinity of the opening, the portion that communicates the inside and outside of the peripheral wall 1 becomes the vicinity of the opening 3, and the length from the opening end of the closing piece 5 that closes the communicating portion is short. Can save material.

  Further, the mounting portion 41 is formed by cutting and raising the peripheral wall 1 so that the central portion protrudes outward from the peripheral wall 1 in a state where both ends are connected to the peripheral wall 1. The through-hole 42 into which the support member S can be inserted can be easily formed simply by cutting it up in a continuous state with 1 and surrounds the outer surface of the support member S (bar material S1) in a planar shape and simply penetrates into a plate-like one. More stable attachment is possible than providing a hole.

  Further, since the closing piece 5 is folded back without protruding to the opening direction side from the opening end, a wall material or a concrete mold standing on the opening side, a box cover attached to the opening, etc. The entire open end can be brought into contact.

Moreover, since the attachment part 41 is provided so that it may be attached in the position which does not interfere with the cable or electric wire inlet N provided in the surrounding wall 1, the support member S (bar material S1) crosses over the inlet N. Therefore, the substantial opening area of the inlet N is not reduced, and the inlet N itself cannot be used.

  Then, 2nd embodiment of this invention is described based on FIGS. Reference numeral B in the figure is a metal box, for example, embedded in a concrete wall so that the opening faces the front side of the wall, and accommodates a switch, an outlet or the like installed on the wall. In addition, about the structure which is the same as that of 1st embodiment, or equivalent, it is the same code | symbol and the description is abbreviate | omitted.

  The metal box B includes a cylindrical peripheral wall 1, an opening 3 surrounded by the peripheral wall 1 on one side of the peripheral wall 1, and the peripheral wall 1 assembled to the other side of the peripheral wall 1 so as to face the opening 3. And a bottom wall 2 formed in a separate metal plate shape, and the bottom wall 2 is assembled to the peripheral wall 1 to form a bottomed box shape. The peripheral wall 1 and the bottom wall 2 are provided with a plurality of introduction ports N through which cables and electric wires formed in a state of being closed by a removable cover plate N1 can be introduced.

  Specifically, a square cylindrical peripheral wall 1 formed by drawing a single metal plate by pressing and a square plate-like bottom wall 2 formed by pressing one metal plate are provided. The peripheral wall 1 has an opening 3 on one side and a bottom wall assembly portion 14 for assembling the bottom wall 2 on the other side. The bottom wall assembling portion 14 is bent from the other end of the peripheral wall 1 to the inner side of the peripheral wall without protruding from the other end, and is provided at one place on each of the opposing peripheral walls (1b, 1d). Further, the bottom wall 2 is provided with a fixing hole 25 at a position corresponding to the bottom wall mounting piece 14, and a screw (not shown) screwed into the bottom wall mounting piece 14 through the fixing hole 25, The wall 2 is assembled to the peripheral wall 1 and integrated.

  The peripheral wall 1 is provided with an attachment piece 11 of a box cover that is bent toward the inside of the peripheral wall at one end and a partition plate holding portion 12 that holds a partition plate that partitions the inside. The partition plate holding portion 12 is similarly provided at the other end of the peripheral wall at a position corresponding to the one end. Further, in the vicinity of the other end of the pair of peripheral walls (1a and 1c) among the opposing peripheral walls (1a and 1c, or 1b and 1d), a cut and raised portion 4 that is cut and raised toward the outside of the peripheral wall is provided. ing. Specifically, a total of four raised portions (4a and 4b, and 4c and 4d) are provided on the opposing wall surfaces (1a and 1c) with two spaces between each other. As in the first embodiment, these cut-and-raised portions 4 are cut in a strip shape so that the central portion bulges outward from the peripheral wall with both ends connected to the peripheral wall 1. It is formed by waking up. Each cut and raised portion 4 includes an attachment portion 41 to which a support member S for supporting the metal box B is attached. In detail, the attachment part 41 is comprised by the through-hole 42 which can insert the said supporting member between the cut-and-raised inner surface and the surrounding wall outer surface. And in the state which has not assembled | attached the bottom wall 2, the communication location which connects the surrounding wall inside and the exterior has arisen by forming the said raising part 4. As shown in FIG. In addition, the support member S utilized here assumes the metal column-shaped bar material S1 (refer FIG. 11) similar to 1st embodiment. Moreover, the said cut-and-raised part 4 uses 2 places as 1 set (4a and 4b and 4c and 4d are 1 set, respectively) similarly to said 1st embodiment. A receiving opening 43 into which the bulging portion S1a of the bar material S1 enters is formed in one of the raised portions (4a, 4d) in each set.

  The bottom wall 2 is formed in the shape of a square plate that is large enough to block the entire other peripheral wall, and the closing piece 5 is provided at a position corresponding to the communication location in a state assembled to the peripheral wall 1. ing. More specifically, four closed pieces (5a, 5b, 5c, 5d) are bent from the outer edge so as to be along the inner surface of the peripheral wall in the assembled state with respect to the peripheral wall 1 having four communication locations. . Of the four closing pieces, two closing pieces (5a and 5b and 5c and 5d) are connected to each other. In order to prevent the connected portions from interfering with the introduction port N of the peripheral wall 1 in the assembled state, the interfering portions are escaped.

  Further, the bottom wall 2 is provided with a contact portion 26 that is in contact with the entire other end of the peripheral wall 1 in a state assembled to the peripheral wall 1. The abutting portions 26 are respectively folded back from the outer edges of the four sides and formed so that the side facing the other end of the peripheral wall is on the same plane when assembled to the peripheral wall 1. And the said closing piece 5 is extended to the front-end | tip of two sides which oppose among the said contact parts 26. As shown in FIG. In other words, a place where the closing piece 5 is not provided so as to constitute the same plane as the contact portion of the closing piece 5 which is bent from the outer edge of the bottom wall and arranged along the inner surface of the surrounding wall. In addition, a contact portion 26 that contacts the entire other end of the peripheral wall 1 by folding back from the outer edge is provided.

  Next, the effect of the metal box of this second embodiment will be described. According to this metal box B, when providing the attachment part 41 for attaching the support member S (bar material S1), the inside of the metal box B generated by cutting and raising a part of the peripheral wall 1 to the outside. Since the communication portion between the outer wall and the outside is closed by the closing piece 5 provided on the bottom wall 2, the communication portion needs to be cured after the support member S is attached to the attachment portion 41 of the cut and raised portion 4. There is no. Further, since the support member S (bar material S1) does not pass through the inside of the peripheral wall and is attached to the outside of the peripheral wall, the internal space is not reduced.

  Moreover, since the attachment part 41 is formed by the through-hole 42, the attachment part 41 is only against the radial force of the support member S (bar material S1) simply by inserting the support member S (bar material S1). Stable attachment is possible without coming out from the radial direction.

Can be shortened, saving material.

  Further, the mounting portion 41 is formed by cutting and raising the peripheral wall 1 so that the central portion protrudes outward from the peripheral wall 1 in a state where both ends are connected to the peripheral wall 1. The through-hole 42 into which the support member S can be inserted can be easily formed simply by cutting it up in a continuous state. The outer surface of the support member S (bar material S1) is surrounded in a planar shape, and the plate-like one simply has a through-hole. More stable attachment is possible than providing the above.

  Moreover, since the attachment part 41 is provided so that it may be attached in the position which does not interfere with the cable or electric wire inlet N provided in the surrounding wall 1, the support member S (bar material S1) crosses over the inlet N. Therefore, the substantial opening area of the inlet N is not reduced, and the inlet itself cannot be used.

  Moreover, since the partition plate holding | maintenance part 12 can be formed from the both ends of the surrounding wall 1, since a partition plate is hold | maintained by both the opening 3 side and the bottom wall 2 side, a partition plate can be hold | maintained stably.

In addition, according to the second embodiment, there is an effect particularly in the following case. That is, it is possible to remove the bottom wall 2 in a state where one end (opening 3 side) of the peripheral wall is fixed so as to come into contact with the formwork, and to perform the work of connecting the cable introduced into the inside. At this time, the communication location remains generated, but the bottom wall 2 is naturally assembled at the time of placing the concrete, and the communication location is closed by the bottom wall 2. In other words, since the communication location generated by cutting and raising the peripheral wall to provide the attachment portion 41 is closed by the bottom wall 2 to be assembled, there is no need to separately cure.

  Among the opposing peripheral walls (1a and 1c, or 1b and 1d), the attachment pieces 11 of the metal cover C are respectively directed toward the opposing peripheral walls on the inner side of the peripheral wall at the opening end of one pair (1b and 1d). It is bent. The outer surface on the opening direction side of the mounting piece 11 is positioned substantially on the same plane as the opening end surface without protruding toward the opening direction. A partition plate holding portion 12 that holds a partition plate for partitioning the inside of the metal wiring box is provided on the inner side of the pair of peripheral walls (1b and 1d) having the mounting piece 11. The partition plate holding portion 12 is composed of a pair of holding pieces that are bent inward from the opening end and further turned back toward the bottom wall. The space between the holding pieces is substantially the same as the thickness of the partition plate, and it is as if the partition plate is inserted between the pair of holding pieces through the opening 3 in a state where the metal cover C is not assembled. As standing from the bottom wall 2, both ends are held by both partition plate holding portions 12 respectively provided on one pair of the peripheral walls 1 to partition the inside of the box (in the illustrated metal wiring box, The inside can be divided into two. Each holding piece of the partition plate holding portion 12 is located on the substantially same plane as the opening end face without projecting to the opening direction side, similarly to the mounting piece 11. .

  And the peripheral wall (1a and 1c) of the other pair (the side on which the mounting piece and the partition plate holding part are not provided) of the opposing peripheral walls is located outside the peripheral wall between the introduction port N and the open end. A cut-and-raised part 4 cut and raised is provided, and the cut-and-raised part 4 includes the metal arrangement A (a metal box B and a metal cover C assembled to the metal box B). An attachment portion 41 for attaching a support member S for supporting the metal arrangement A) is provided. The cut-and-raised part 4 is provided at a total of four locations, two at each of the other pair of peripheral walls. (In other words, a total of four places are provided on two opposing walls of the square cylindrical peripheral wall.) These cut and raised portions (4a, 4b, 4c, 4d) It is used to attach support members as a set, and two sets of cut and raised portions (4a and 4b and 4c and 4d) provided on the other pair of peripheral walls (1a and 1c) respectively, Support members S are attached to the respective walls.

  More specifically, the cut-and-raised part 4 is located in the vicinity of the open end of the cut-and-raised peripheral wall 1 so that the center part of the cut-and-raised part 4 bulges outward from the peripheral wall 1 with both ends connected to the peripheral wall 1. Is formed by cutting and raising a part of the belt. Then, a through hole 42 through which the support member is inserted is formed between the cut and raised inner surface and the outer peripheral surface of the peripheral wall (on both sides of the cut and raised portion), and the attachment portion 41 to which the support member S can be attached is configured. is doing. The support member S used here is made of a metal cylindrical bar material S1 (see FIG. 11), as in the first embodiment, and more specifically, is crushed to a part in the axial direction. A bulging portion S1a bulging outward is provided. The bar material S1 can be bent in a three-dimensional direction by hand and has a predetermined tensile strength.

A widened receiving port 43 for the bulging portion S1a of the bar material to enter is formed on the (bar material insertion source side), and gradually tapers from the receiving port 43 toward the cut and raised portion on the other side. Eventually, the bar material S1 is narrowed to such a size that only the shaft of the bar material S1 can pass through. Therefore, the bulging portion S1a that has entered contacts the inner surface of the receiving port, restricts further movement of the bar material S1 in the axial direction, and further, through the contact between the inner surface of the receiving port and the bulging portion S1a. The rotation of the bar material S1 relative to 42 in the circumferential direction can be prevented. In the present embodiment, the through hole 42 of the other raised portion (4b or 4c) is not formed with the receiving port 43 formed in the one raised portion (4a or 4d). Instead, a through hole 42 having a size through which only the shaft of the bar material S1 can pass is formed. The receiving port 43 is formed in a size that allows the entire bulging portion S1a to enter.

  Next, the metal cover C that is assembled to the metal box B and constitutes the metal arrangement A will be described. The metal cover C is configured as a square plate formed by press-molding one metal plate. More specifically, a square plate-like base 90 and a window 91 passing through the base 90 are provided at the center thereof, and the window 91 is surrounded by a rising wall 93 rising from the base 90.

An internal space for accommodating wiring devices, cable connection portions, etc. is formed inside the wall surrounded by the bottom wall 2 and the peripheral wall 1, and an opening for facing the internal space to the outside 3 is provided to face the bottom wall 2. The bottom wall 2 is formed with five holes that pass through without being blocked, and screw holes 21 into which screws for ground wiring are screwed, and a fixing tool for fixing a metal wiring box are attached. And four fixing holes 22 (which are generally attached using two of the four, depending on the form of the fixture). These five holes are generally sold in a state where all of them are closed by a closing tape 24 (a chain line in the figure).

  Box cover mounting pieces 11 are bent toward the inner space at the opening ends of one pair of peripheral walls (1b and 1d) among the opposing peripheral walls (1a and 1c and 1b and 1d). . The mounting piece 11 has an outer surface on the opening direction side located on the same plane as the opening end surface, and does not protrude toward the opening direction. Furthermore, a partition plate holding portion 12 that holds a partition plate that partitions the internal space is provided inside one pair of peripheral walls (1b and 1d) having the mounting piece 11. The partition plate holding portion 12 is composed of a pair of holding pieces which are bent inward from the opening end and further turned back toward the bottom wall 2. The space between the holding pieces is substantially the same as the thickness of the partition plate. By inserting the partition plate between the holding pieces through the opening, the partition plate is held upright from the bottom wall 2 to partition the internal space. (In the illustrated metal wiring box, the internal space is divided into two). Similarly to the mounting piece 11, the holding piece also has an outer surface on the opening direction side located on the same plane as the opening end face and does not protrude toward the opening direction.

  Further, the peripheral wall (1a and 1c) of the other pair (the side where the mounting piece and the holding piece are not formed) of the peripheral walls facing each other in the peripheral wall 1 is extended outwardly from the opening end of the peripheral wall. A piece 6 is provided. The extension piece 6 is bent in a state where the tip faces the bottom wall so as to overlap with the peripheral wall along the outer peripheral surface, and the outer surface on the opening direction side is located on the same plane as the opening end surface, It does not protrude toward the opening direction. Further, the extension piece 6 is formed by attaching the support member S for supporting the metal box B (specifically, the inner side surrounded by the outer edge is cut and raised so as to leave the outer edge). A through hole 42) through which the support member S is inserted is provided. As shown in FIG. 11, the supporting member S used here is made of a conventionally used metal columnar bar material S1, and is crushed and bulged outward in a part of the axial direction. A bulging portion S1a is provided. The bar material S1 can be bent in a three-dimensional direction by hand and has a predetermined tensile strength.

  Specifically, the extension piece 6 is bent around the base end along the peripheral wall so that the distal end side faces the bottom wall side with the base end connected to the opening end of the peripheral wall. In the bent state, the opening end of the base end is set to be flush with the opening end surface of the peripheral wall 1. And in the state where only the base end side and the tip end side are connected to the central portion of the portion overlapping with the peripheral wall of the extension piece 6, the space between the connection portions is directed outwardly from the peripheral wall and is substantially triangular. Thus, a cut-and-raised part 4 is formed which is cut and raised so that its apex is arcuate. Neither the extension piece 6 nor the cut-and-raised portion 4 provided on the extension piece protrudes toward the opening direction side from the opening end face of the peripheral wall.

  The cut-and-raised part 4 is cut and raised on the inner side surrounded by the outer edge so as to leave the outer edge of the extending piece 6, and the inner surface and the outer surface of the outer edge are A through hole 42 through which the bar material S1 can be inserted is formed. The through hole 42 is formed so as to continuously surround the entire outer circumferential direction of the bar material S1 by the cut inner surface and the outer edge of the extended piece, and the inserted bar material. The separation from the extended piece 6 (from the metal box B) due to the radial movement of S1 is prevented. In addition, only the part that is cut and raised from the peripheral wall 1 protrudes outward, and the extension piece 6 can be made smaller than that protruded outward from the peripheral wall, and is not bulky during storage and packaging. Furthermore, since the cut-and-raised portion is formed in an arc shape, there is no risk of injury by catching fingers. The through hole 42 can be inserted through the attachment portion 41 by moving in the axial direction from the end portion of the support member S (bar material S1).

  The extension pieces 6 are provided at two locations on the opposite pair of peripheral walls (1a and 1c), and two extension pieces (6a and 6b and 6c and 6d) provided on the same peripheral wall. Each is provided with a through hole 42. The two through-holes 42 have the same penetration axis so as to be able to penetrate one bar material S1 formed in a straight line. More specifically, the axis of the bar member S1 inserted through the through hole 42 of each extending piece 6 extends along one side of the peripheral wall end (opening end) serving as the base end of each extending piece 6. It is provided so that the outer peripheral surface along which the piece 6 extends and the axis are parallel. For this reason, the bar member S1 inserted through the through hole 42 formed by one extending piece 6 (for example, 6a) is brought into contact with the inner surface of the through hole or the outer surface of the peripheral wall while the other extending piece is in contact with the bar member S1. (E.g., 6b) can go straight to the through-hole 42, one end is inserted through the through-hole, and the bar material is linearly moved in the insertion direction, so that the peripheral wall outer surface and one of The other through-hole 42 can be passed smoothly while being guided by the inner surface of the through-hole. When one end surface of the bar material that has reached the other extending piece is caught by the outer edge of the other extending piece 6, the bar extends over the outer edge, so that it is immediately directed to the other through hole 42. You can make it.

  Moreover, the through-hole 42 formed in one extension piece (6a of 6a and 6b and 6d of 6c and 6d) of the two extended pieces provided on the same peripheral wall is the other On the side opposite to the extended piece (6b or 6c) of (the insertion source side of the bar material), a widened receiving port 43 is formed for the bulging portion S1a formed in the bar material S1 to enter, The taper gradually tapers from the receiving port 43 toward the other extending piece, and finally narrows to such a size that only the shaft of the bar material S1 can pass through. Therefore, the bulging portion S1a that has entered comes into contact with the inner surface of the receiving port, and further movement of the bar material in the axial direction is restricted. Furthermore, the circumferential rotation of the support bar with respect to the through hole 42 is prevented by the contact between the inner surface of the receiving port and the bulging portion. For this reason, it is possible to restrict the movement in the axial direction and prevent the rotation in the circumferential direction only by bringing the inner surface of the receiving port into contact with the outer surface of the bulging portion. In the present embodiment, the through hole of the other extending piece (6b or 6c) is a receiving port 43 through which the bulging portion S1a formed in the one through hole (6a or 6d) enters. Is not formed, and the size is such that only the shaft of the bar material S1 can pass through.

  Each bar material attached to each extended piece of the two places as one set is in a position where it does not cross the introduction port N provided in the peripheral wall along which the bar material extends. Furthermore, when the connector for connecting the conduit to the introduction port N is removed by removing the cover plate N1 that closes the introduction port N, the introduction is performed so as not to hinder the attachment. It is located near the opening end away from the mouth N.

  Next, a procedure for attaching the bar material S1 to the metal box B using the through hole 42 will be described. First, one end of the bar material S1 is passed through one through hole (1a or 1d) (a through hole formed in one extending piece and having the receiving port). Subsequently, the bar material S1 is moved in the axial direction as it is, so that one end of the bar material passes through the other through hole (1b or 1c) and the bulging portion S1a is applied to the inner surface of the one through hole. Make contact. Thereby, the bar material S1 is attached in a state where the movement of the bar material in the axial direction of the bulging portion S1a is restricted by the inner surface of the through hole. In this state, as shown in FIG. 43, the length from the one through hole (1a or 1b) and the other through hole (1b or 1c) to both ends of the bar member S1 that protrudes from each other. Are formed at predetermined positions in the axial direction of the support bar S1.

  Next, the effect of the metal box B having the above configuration will be described. According to this metal box B, the attachment portion 41 for attaching the support member S (bar material S1) does not allow the internal space surrounded by the peripheral wall 1 provided in the metal box B to communicate with the outside. For this reason, the attachment portion 41 can be provided outside the peripheral wall 1 independently of the internal space, and the work such as curing can be saved after the support member S (bar material S1) is attached. In addition, the support member S (bar material S1) does not pass through the internal housing space surrounded by the peripheral wall 1, and the support member (bar material) can be attached to the outside of the peripheral wall, thereby narrowing the internal space. No.

  Further, since the attachment portion 41 is formed by the through hole 42, the support member S is attached to the radial force of the support member (bar material) only by inserting the support member S (bar material S1). Stable attachment is possible without coming out of the portion 41 in the radial direction.

  Further, since the through hole 42 is formed by raising the inner side surrounded by the outer edge so as to leave the outer edge of the extending piece 6, the outer surface of the support member S (bar material S1) is faced. More stable attachment can be achieved than simply providing a through-hole in a plate-shaped object.

  Further, the extended piece 6 is bent along the peripheral wall 1 and only the cut-and-raised part forming the through hole 42 through which the support member S (bar material S1) is inserted is the extended piece 6. Protrudes outward from the surrounding wall. For this reason, the part which protrudes outward from the surrounding wall 1 becomes only the part cut and raised, and it can be made small compared with what protrudes outward from the surrounding wall 1 with the extension piece 6, and does not become bulky at the time of storage and packing. .

  Further, since the extension piece 1 and the attachment portion 41 provided on the extension piece are both provided so as not to protrude toward the opening direction from one end of the peripheral wall, they do not protrude toward the opening direction side from one end of the peripheral wall. Thus, the opening end (one end of the peripheral wall) can be brought into contact with the formwork when embedding concrete, the opening of the wall material standing on the opening side, the lid member attached to the opening, etc. When the (one peripheral wall end) is brought into contact with the surface facing the opening, it does not get in the way.

  Further, by providing the attachment portion 41 on the extended piece 6 that is folded back from the opening end, a through hole 42 for attaching the support member S (bar material S1) can be formed at a position near the opening end, and is provided in the peripheral wall 1. The extension piece 6 and the attachment portion 42 can be provided at a position away from the introduction port N so as not to interfere with the cable introduction port N. Further, when attaching the conduit connector to the introduction port N, the support member S (bar material S1) can be attached at a distant position that does not interfere with the attachment.

  The seventh embodiment may be modified as follows. That is, the extension piece 6 is provided on two planes (1a and 1c) of the peripheral wall, but may be provided on only one plane (for example, only 1b), and three planes (for example, 1a, 1b, 1c) or all the planes (1a, 1b, 1c, 1d) constituting the peripheral wall.

As shown in FIGS. 44 to 45, the extending piece 6 may be bent so as to extend outward from the peripheral wall 1 in parallel with the opening surface without being along the outer surface of the peripheral wall 1. At this time, the mounting portion 41 is cut and raised so as to bulge toward the opposite side (bottom wall side) of the opening direction of the peripheral wall 1. Even in this case, the surface of the extending piece 6 on the opening direction side does not protrude in the opening direction from the opening end, and the attachment portion 41 does not protrude. In this example, the four attachment portions 41 are all in the same form, and the bulging portion S1a formed on the support member S (bar material S1) is the same as in the seventh embodiment. The entrance 43 for entering is not formed. However, the surface of the extended piece 6 on the bottom wall side and the bulging portion S1a come into contact with each other to prevent the support member S (bar material S1) from rotating in the circumferential direction and to come into contact with the cut through and raised edge of the through hole. The above axial movement is restricted. (In this example, the extending piece 6 is parallel to the opening surface, but may be inclined with respect to the opening surface toward the side that does not protrude in the opening direction from the opening end.)

◯ Even though the through hole 42 does not surround the support member S in the outer peripheral direction without interruption, a part of the outer peripheral direction may be interrupted as shown in FIGS. 46 to 48. Specifically, the extension piece 6 is bent along the outer surface of the peripheral wall 1 in a state of being separated from the peripheral wall end from the peripheral wall end, and the auxiliary piece cut and raised from the extension piece 6 toward the peripheral wall 1. It has. The extension piece 6 and the auxiliary piece 61 cut and raised form a through hole 42 through which the support member S (bar material S1) can be inserted. In this example, a total of eight extending pieces 6 are provided on each of the four peripheral walls (1a, 1b, 1c, 1d) constituting the rectangular cylindrical peripheral wall 1. Further, the bulging portion S1a formed on the support member S (bar material S1) is in contact with the extended piece and the outer surface of the peripheral wall, so that the rotation of the support member (bar material) in the circumferential direction is restricted.

The extension piece 6 and the through hole 42 may be configured as shown in FIGS. That is, it is good also as the substantially U-shaped extension piece 6 which was bend | folded so that it might stand upright from the surrounding wall 1 from the opening end of the surrounding wall 1, and was bent toward the bottom wall side. . And the through-hole 42 is formed in the location bent toward the bottom wall side. The through-hole 42 has a shape for receiving the bulging portion S1a provided on the support member S (bar material S1) on the outside (the side on which the end of the support member is inserted first), and on the inside (The side where the end portion of the support member is inserted next) has a shape substantially the same diameter as the shaft of the support member S (bar material S1). Therefore, the bulging portion S1a is allowed to enter the outer through-hole 42, and further axial movement is restricted. In addition, when providing the through-hole 42 in the extension piece 6, you may comprise only a simple through-hole 42 as shown in FIG. In this example, the support member is attached along a surface different from the surface of the peripheral wall serving as the base end of the extension piece 6.
(Eighth embodiment)

  Next, an eighth embodiment of the present invention will be described with reference to FIGS. The symbol B in the figure is a metal box, for example, a switch embedded in a concrete wall or concealed in a hollow wall, with the other opening facing the wall surface wall, An outlet or the like is accommodated inside. In addition, about the structure which is the same as that of other embodiment, or equivalent, it is set as the same code | symbol, and the description is abbreviate | omitted.

  The metal box B includes a polygonal cylindrical peripheral wall 1 having an opening 3 on one side, and a bottom wall 2 that is formed in a separate metal plate shape from the peripheral wall 1 and assembled to the other of the peripheral wall 1. It is formed in the shape of a polygonal bottomed box. The peripheral wall 1 is provided with a peripheral wall extending piece 7 that is extended from an opening end of at least one plane constituting the peripheral wall 1 and is bent toward the bottom wall 2 along the outer surface of the peripheral wall. Specifically, in this embodiment, the peripheral wall bent toward the bottom wall side (the end opposite to the opening end of the peripheral wall) from the opening ends of the two opposing flat surfaces of the rectangular cylindrical peripheral wall 1. An extending piece 7 is provided. The peripheral wall extending piece 7 is provided without protruding in the opening direction from the opening end.

  Further, the bottom wall 2 is opposed to the peripheral wall extending piece 7 and extends from an outer edge, and is bent toward the opening 3 along the outer peripheral surface along which the peripheral wall extending piece 7 extends. An extending piece 8 is provided. Specifically, it is a square plate-like bottom wall 2 that is assembled to the other of the peripheral walls by screws P, and in an assembled state, is opened from the edge corresponding to the peripheral wall extension piece 7 along the outer surface of the peripheral wall. A bottom wall extending piece 8 bent toward the side is provided.

  And in this embodiment, as shown in FIG. 55, the support member S for supporting the metal box B includes a fixed part S3a fixed to a structure and the metal part B extended from the fixed part S3a. A plate-like support portion S3b that is attached to the box B and supports the metal box B, and the fixing portion S3a fixed to the structure is installed in a hollow wall. It is assumed that a plurality of fixing holes S3c for fixing to a pillar with screws, nails or the like are provided, and the support portion S3b is formed in a plate shape continuously extending the same width away from the fixing portion S3a. ing.

  Then, by inserting the support portion S3b between the extended pieces (between the peripheral wall extended piece 7 and the bottom wall extended piece 8), the extended pieces (7, 8) cooperate. The support member S3 is attached so as to hold the support portion S3b from both sides. Specifically, each of the extending pieces (7, 8) is separated from the outer peripheral wall surface along which the extending pieces (7, 8) extend, and the support member S3 is interposed between the extending pieces (7, 8). ) Are formed in cooperation with each other along the outer surface of the peripheral wall. (In other words, the peripheral wall extending piece 7 and the bottom wall extending piece 8 are separated from the outer peripheral wall surface along which the peripheral wall extends, and the support member S3 can be inserted between the peripheral wall 1). The peripheral wall provided with the two extending pieces (7, 8) is provided with an introduction port N through which a cable or the like can be introduced. When the support member S3 is used to support it, The inlet N cannot be used. (A support member is attached and supported on the surface where the introduction port is not used, or the introduction port is used if a through hole is provided in the support portion S3b that interferes with the introduction port. be able to.)

  Next, the effect of the metal box B having the above configuration will be described. According to this metal box B, when the mounting portion 41 for mounting the support member S is provided, the internal space surrounded by the peripheral wall 1 provided in the metal box B does not communicate with the outside. For this reason, the attachment portion 41 can be provided outside the peripheral wall 1 independently of the internal space, and it is possible to save troubles such as curing after the support member is attached. In addition, the support member S can be attached to the outside of the peripheral wall 1 without passing through the internal housing space surrounded by the peripheral wall 1, and the internal space is not narrowed.

  Further, both the extending pieces (7, 8) are bent along the peripheral wall 1. For this reason, the part which protrudes outward from the surrounding wall 1 is small, and does not become bulky at the time of storage and packing.

  Further, the peripheral wall extending piece 7 does not protrude toward the opening direction side from one end of the peripheral wall, so that the opening end (one end of the peripheral wall) is embedded in the concrete, the opening of the wall material standing on the opening side, It can be brought into contact with a lid member or the like attached to the opening, and does not get in the way when the opening end (one end of the peripheral wall) is brought into contact with the surface facing the opening.

  Moreover, when forming the attachment part 41, it is not necessary to weld an attachment part separately to the surrounding wall 1 or the bottom wall 2, and it can shape | mold in the process of forming a surrounding wall or a bottom wall, and its shaping | molding efficiency is good. (In addition, the same effect is exhibited in each of the other embodiments described above.)

Moreover, the support member S is attached along the direction along the circumferential direction of the surrounding wall 1 similarly to each other embodiment mentioned above.
In addition, you may change each embodiment mentioned above and its modification as follows.

O The receiving port 43 is not limited to one side (for example, 4a and 4d in the first embodiment) of the pair of cut and raised portions (for example, 4a and 4b and 4c and 4d in the first embodiment). You may provide similarly in the side cut-and-raised part (for example, 4b and 4c in 1st Embodiment). According to this, either cut-and-raised part can be used as an insertion source of the support member S (bar material S1). Further, the receiving opening 43 provided in the cut-out portion on one side is omitted, and only the shaft of the support member S (bar material S1) passes through all the cut-out portions, and the bulging portion S1a does not pass. good.

O Although the bulging part S1a is formed in the bar material S1 as the support member S, the bulging part S1a may be omitted. Moreover, although demonstrated by the bar material which can be bent by hand, the linear bar material which cannot be bent by hand like a 3 minute bolt or a reinforcing bar may be sufficient. Further, the bar member may have a polygonal column shape or a plate shape, instead of a columnar shape in which the cross section of the bar material is a perfect circle. In that case, the attachment portion 41 (and the through hole 42) may be formed into a shape corresponding to the support member.

In each embodiment, the peripheral wall 1 has a rectangular tube shape, but may have an octagonal shape or a long rectangular shape. In addition, a metal box cover C or a bottom that is fixed so as to close (or at least partially expose) at least a part of the opening 3 of the peripheral wall 1 according to the opening 3 changed according to the shape of the peripheral wall 1. It is desirable to change the wall 2 to an octagonal shape or a long rectangular shape.

In each embodiment and modification, the box cover attachment piece 11 and the partition plate holding part 12 are provided on a surface different from the outer surface of the peripheral wall 1 along which the support member S mainly extends. You may form in the inner surface of the surrounding surrounding wall 1.

In each embodiment and modification, both the box cover mounting piece 11 and the partition plate holding portion 12 may be the same surface or different surfaces of the peripheral wall 1, and the number and arrangement may be changed.

In each embodiment, the metal arrangement A and the metal box B are mainly shown as being embedded in a concrete wall, but the wall material is erected so that the space between the wall materials is hollow. It may be concealed in the wall. Since it is possible to provide the mounting portion 41 of the support member S without providing a location where the internal space and the outside of the metal box B or metal arrangement A communicate with each other, This is particularly effective when the hollow wall constitutes a fireproof compartment wall. That is, although the interior side of the indoor arrangement and the metal arrangement A (metal box B) communicates with each other through the wall hole formed in the wall material, the metal arrangement A (metal box B). Because the inner space and the outer space of the support member S are provided without the location where the inner space and the exterior of the metal arrangement A (metal box B) communicate with each other, a fire occurs indoors. Even if this occurs, smoke or toxic gas does not leak out from the metal arrangement A (metal box B) to the outside (inside the hollow wall). (Of course, the cable introduction port N formed irrespective of the provision of the mounting portion 41, the screw hole 21 into which the screw for grounding wiring is screwed, or the like in the embodiment, for example, It is necessary to close the four fixing holes 22 and the like for attaching the fixing tool for the purpose.)

In each embodiment and modification, the attachment portion 41 of the support member S is inserted into the through hole 42 at two positions shifted in the axial direction with respect to one support member S (bar material or three-part bolt). The support member S is configured to be exposed between the two locations, but the portion through which the support member S is inserted may be one, or between the two through holes. It is good also as the cylindrical through-hole 42 extended along the axial direction of the supporting member S by making the through-hole continue so that S may not be exposed. Furthermore, although the metal box B was directly or indirectly supported by the two support members S, if it can be supported, only one support member S may be used, and the number of attachment portions 41 may be increased, It may be supported by three or more support members. In particular, when the support member mounting portions 41 are provided on all the surfaces of the rectangular frame-shaped peripheral wall 1, both the two surfaces are selected when the support members are attached to the two opposing peripheral walls. It is possible to flexibly correspond to the fixing direction of the metal box B and the metal arrangement A and the installation position of the support member. Also in this case, the number of attachment portions provided on each surface is not limited to two, but may be changed to one or more than three.

O The five holes (21, 22, 23) provided in the bottom wall 2 of each embodiment may be closed with knocks. In this case, the closing tape 24 can be omitted. Further, some or all of the five holes may be omitted.

In the first embodiment, the fifth to seventh embodiments, and modifications thereof, the bottom wall 2 is press-molded integrally with the peripheral wall 1, but the bottom wall 2 and the peripheral wall 1 are separately molded and assembled to each other to form a metal Box B may be configured.

In each embodiment, the peripheral wall has a rectangular tube shape, and the closing pieces are arranged so as to be aligned along two opposing sides, but a closing piece may be provided on each side. (In other words, two of the four walls constituting the peripheral wall are provided with two closing pieces, but one of the four walls may be provided so as to block the internal and external communication locations. )
