Description

  The present invention relates to a bus duct support device, and more particularly to an improvement of a bus duct support device that flexibly supports a bus duct laid in a vertical direction on a building with a predetermined component of the building.

  The installation of the bus duct in the building is not limited to the case where the bus duct is installed so as to extend in the horizontal direction, but may be installed vertically through a plurality of floors and ceilings. In the installation of such a vertical bus duct, a structure part such as a floor part structure or a ceiling part structure of each level is inevitably passed. However, if the bus duct is completely fixed with respect to these structural portions, the fixed state is hindered when the bus duct expands due to a temperature rise during use. This is especially true for long bus ducts installed in high-rise buildings, and the problem becomes prominent.

  Therefore, when laying the bus duct vertically, the installation at the bottom of the bus duct is done by firmly fixing it to the installation surface, but the mounting relationship between the structure part of each floor of the building and the bus duct is Instead of being completely fixed, a structure is used in which it is supported flexibly by the floor of each floor.

  For example, in the bus duct support device disclosed in Patent Document 1, a fixing bracket (13) is attached to the outer surface of the flange portion (14) of the bus duct as a structure on the vertical bus duct side, and a clamp piece (20) is attached to the fixing bracket (13). ing. And the foundation member (16) is being fixed on the floor (11) as a structure part by the side of a floor (11). A vertical bus duct is flexibly supported on the floor by interposing a spring (19) regulated by a supporting bolt (17) for guidance between the bus duct side structure and the floor side structure. In addition, the lowermost part of the vertical bus duct has its lower end fixedly installed on the lowermost floor.

  Also, the bus duct support device of Patent Document 2 includes a bus duct side mounting member (such as a receiving plate 45) and a floor (60) side mounting member (a channel member (46) and a spring guide support bolt (47)). By interposing a spring (48) between them, the vertical bus duct is flexibly supported on the floor (60).

Japanese Utility Model Publication No. 61-114925 Japanese Patent Laid-Open No. 53-133798

  However, when the bus duct is flexibly supported by each structure portion, the weight of the bus duct varies depending on the capacity thereof, so that it is necessary to adjust the number of urging means such as a spring according to the procedure. That is, in the case of a large capacity, it is necessary to increase the number of biasing means in order to accurately perform the flexible support. On the other hand, as is clear from the technique disclosed in the above-mentioned patent document, when a spring or the like is installed, a support bolt is inserted into the spring in order to restrict lateral displacement of the spring or the bus duct itself. And the structure for attachment of these support bolts is provided for every hierarchy.

  Therefore, the increase in the number of structures for such a flexible support leads to an increase in cost. Further, in the case of Patent Document 2 or the like, when the number of support bolts is increased, the distance between the support bolts is inevitably narrowed. Therefore, it becomes difficult to perform a work (rotating operation) with a tool for attaching and detaching the support bolt and a nut screwed to the support bolt and moving the position. In order to avoid this problem, it is not preferable to enlarge the mounting part (such as the width of the backing plate) of a member such as a support bolt, which leads to an increase in installation space. In addition, when the width of the backing plate is increased as described above, in a situation where a plurality of bus ducts are juxtaposed, the distance between the bus ducts must be provided more than necessary, creating a useless space. The problem that occurs.

  The present invention has been made in view of the above problems, and its object is to support a bus duct capable of increasing the urging means for flexible support without enlarging the structure and making the tool difficult to use. To provide an apparatus.

A bus duct support device according to claim 1 for solving the above-mentioned problem is as follows.
In a bus duct support device for a vertical laying type bus duct that is installed through each level of a building and is flexibly supported by a floor portion of each floor, a floor-side structure portion and a bus duct-side structure portion disposed above the floor-side structure portion; And a biasing means for biasing the floor-side structure portion and the bus duct-side structure portion in a normal installation state, and a position where the horizontal position of the biasing means can be regulated. Arranged, one end is fixed to one structure part of the floor side structure part or the bus duct side structure part, and the other structure part is not fixed to the other structure part, and the horizontal position is regulated by the other structure part. And a guide member having an adjustment member for maintaining the compression / compression state of the urging means, in addition to the basic support portion, the bus duct side structure portion and the floor portion. Installed between the An urging means for urging the bus duct side structure portion and the floor portion side structure portion away from each other in an installed state; and the attachment provided on at least one of the floor portion side structure portion or the bus duct side structure portion. And an auxiliary support portion comprising a horizontal position restricting means for the biasing means.

  According to this configuration, the guide member (for example, the guide bolt body) of the basic support portion is not only restricted in the horizontal position of the urging means but also in the position restriction between the floor side structure portion and the bus duct side structure portion. And an adjustment member (for example, an adjustment nut) for maintaining the compression / compression state of the urging means used when assembling and attaching the basic support portion. Yes. Therefore, when performing flexible support on the floor of the bus duct using only this basic support portion, a tool for adjusting the adjustment member (for example, rotating the nut) when the number of support portions needs to be increased. It is accompanied by an increase in the size of the structure because of the need to secure space. However, since the auxiliary support portion only includes the biasing means and the member that regulates the position, a tool space for adjusting the adjustment member is unnecessary, and the auxiliary support portions are arranged close to each other. It can be installed close to the basic support. Therefore, by using the basic support portion and the auxiliary support portion together, it is possible to effectively suppress an increase in installation space with respect to an increase in the support portion accompanying an increase in capacity.

The bus duct support device according to claim 2 is:
The basic support portion and the auxiliary support portion are provided side by side. The structure of the auxiliary support part is simple and can be arranged side by side with the basic support part.

The bus duct support device according to claim 3 is:
The basic support portion and the auxiliary support portion are alternately arranged. According to this configuration, the distance between the basic and auxiliary support portions can be made extremely small. That is, since there is no subsequent work such as adjustment work of the adjustment member (for example, rotation work of the nut) on the auxiliary support part, the basic support part and the auxiliary support part are placed close to each other. Even so, there is room for the space between the basic support portions because the auxiliary support portions are interposed, and workability with respect to the basic support portions is not deteriorated. It is possible to increase the urging means that can cope with the large capacity of the bus duct without increasing the size.

The bus duct support device according to claim 4 is:
The auxiliary support portions are provided on both sides of a region where a plurality of the basic support portions are arranged. In this way, various arrangements are possible if the auxiliary support portion is installed adjacent to the basic support portion. That is, by providing a plurality of basic support portions with a space in the center and further installing auxiliary support portions close to both sides thereof, the biasing means can be increased by increasing the space as little as possible.

The bus duct support device according to claim 5 is:
The floor portion side structural portion includes a member for attaching the basic support portion and a member for attaching the auxiliary support portion separately. Thus, for example, when a basic support portion is provided as a standard and an auxiliary support portion is added according to the capacity of the bus duct, a member for attaching the basic support portion is secured in advance as a stock. The member which manufactures and attaches an auxiliary | assistant support part should just be manufactured additionally.

The bus duct support device according to claim 6 is:
Instead of the basic support part, one end is fixed to the floor part side structure part or one structure part of the bus duct side structure part arranged at the upper position thereof, and the other end is not fixed to the other structure part. A guide member having an adjustment member for holding the compressed / compressed state of the urging means is set in a state in which the horizontal position is regulated by the structure portion.

  That is, the basic support portion is configured as a guide member having no biasing means, and the configuration in which the bus duct is flexibly supported on the floor portion restricts the horizontal position of the auxiliary support portion having the biasing means and the bus duct. A guide member is used. As a result, even when the number of urging means is increased, it is possible to avoid the complexity of the structure and to secure an inexpensive manufacturing cost.

  According to the bus duct support device of the present invention, it is possible to increase the biasing means for the flexible support without enlarging the flexible support structure in each level of the vertical laying type bus duct and making the tool difficult to use. Is possible. Thereby, the increase / decrease of the biasing means corresponding to the various capacity | capacitance of a bus duct is achieved.

Hereinafter, embodiments of the bus duct support device of the present invention will be described in detail with reference to the drawings.

(B) is a front view and a side view showing a state in which the support structure is disassembled, and FIGS. 3 (A) and (B) are a front view and a state in which the spring of the support structure is compressed (support unit) and the floor side structure part. Side views, FIGS. 4 (A), (B) and (C) are views showing a method of assembling the support unit.

  FIG. 5 shows an example of a bus duct supported by this embodiment. As shown in the figure, the bus duct 300 is formed by laminating three-phase insulated conductors 305 formed by coating an insulating material 304 on three conductors 302, and a pair of cross-sectionally-shaped cross sections on both sides in the width direction of the insulated conductors 305. A spacer 306 is provided, and is fastened and fixed with fasteners such as bolts and nuts (310, 312) so that the insulating coated conductor 305 and the spacer 306 are sandwiched by the side plates 308 from both sides in the thickness direction of the insulating coated conductor 305. ing. A first reinforcing portion 308a bent outward is formed at both ends (upper and lower ends in the figure) of the side plate 308, and the edges of the first reinforcing portion 308 are bent and extended so as to face each other. It has the 2nd reinforcement part 308b. The bus duct to which the present invention is applied is not limited to such a form.

  The bus duct support device 10 according to the present embodiment shown in FIGS. 1 to 4 supports a bus duct 100 installed in a vertical direction by a spring 12 which is a compressed biasing means, and is based on heat of the bus duct 100 or the like. It has a structure that allows the expansion to escape upward.

  As shown in the figure, first, as the floor side structure provided in the floor 200 of each level of the building, a cross section is formed on the upper surface of the floor 200 in the vicinity of the through hole 202 for allowing the bus duct of the floor 200 to pass therethrough. Two U-shaped first channel members 12-1 and 12-2 are arranged in parallel to the outside of the through-hole 202, and two second channel members 14-1 and 14-2 are arranged in the shape of a well in the upper part thereof. Has been. As shown in FIG. 2, the first channel member 12-1 is fixed to the floor portion 200 with an anchor 13 or the like, and the second channel member 14-1 is bolted to the first channel member 12-1 or the like. The fastening tool 15 is fixed.

  Next, as a bus duct side structure provided in the bus duct 100, first, the base member 20 having a substantially L-shaped cross section attached to the front side and the back side of the bus duct 100 is provided. The base member 20 includes a front surface of the bus duct 100, a spacer outer surface 306 which is the back surface, and a base surface portion 20a made of a flat plate abutting against the outer surface of the first reinforcing portion 308a (see FIG. 5) and the lower end of the base surface portion 20a. The support piece 20b is formed to bend and extend outward. Next, there is a fixing member 22 having a U-shaped cross section disposed so as to cover the second reinforcing portion 308b (see FIG. 5) of the bus duct on the back surface of the base surface portion 20a of the base member 20. . By fastening these with a fastener such as a bolt and nut, the bus duct and the bus duct side structure are in a fixed state.

  Next, an auxiliary member 24 having a U-shaped cross section is provided as a member fixed to the second channel members 14-1 and 14-2, which are the floor side structure portions. A member that flexibly supports the bus duct 100, which is a characteristic component of the present embodiment, by the floor portion 200 is installed between the auxiliary member 24 and the support piece 20 b of the base member 20. That is, the basic support portion 25 and the auxiliary support portion 35 are installed between the auxiliary member 24 and the support piece 20b. In this embodiment, one pair is provided.

  First, the basic support portion 25 is a guide member, a support bolt 26 constituted by a long bolt, and a mounting nut as a fastening member for fixing the support bolt 26 to the first channel member 14-1 and the auxiliary member 24. 28, 30, a spring 32 as an urging means installed in a state where the support bolt 26 is inserted between the auxiliary member 24 and the support piece 20 b, and compression of the spring 32 screwed into the support bolt 26. An adjustment nut 34 which is a guide member for maintaining the compressed state is included.

  Next, the auxiliary support part 35 is attached in a state where the spring 36 is inserted between the auxiliary member 24 and the support piece 20b and the spring 36 is inserted in order to regulate the position of the spring 36 in the horizontal direction. The spring restricting body 38 and a small bolt 40 for attaching the spring restricting body 38 to the auxiliary member 24 are included. In the present embodiment, the spring restricting body 38 is composed of a high nut. Further, as shown in the figure, in the present embodiment, a pair of basic support portions 25 are installed on both sides, and a pair of auxiliary support portions 35 are installed inside thereof.

  The above-described bus duct side structure is almost integrated as one unit as shown in FIG. 3, and is attached to the floor side structure in that state. FIG. 4 schematically shows the assembly process of the bus duct side structure unit. First, as shown in FIG. 2A, a support bolt 26, in which an adjustment nut 34 is screwed into a through hole (not shown) provided in the support piece 20b of the base member 20, is inserted, and an auxiliary is provided. A spring restricting body 38 is fixed to the member 24 with a small bolt 40. Then, the springs 32 and 36 are inserted into the support bolt 26 and the spring restricting body 38, respectively, and the support bolt 26 is inserted into a through hole (not shown) formed in the auxiliary member 24, and the mounting bolt 28 is used to connect the support bolt 26. The auxiliary member 24 is fixed (see FIG. 4B). Finally, by screwing the adjusting nut 34, the spring is compressed, and the bus duct side structural unit is completed (see FIG. 4C). The position of the spring 32 of the basic support portion 25 is restricted by the support bolt 26 in the horizontal direction.

  The height of the spring restricting body 38 is preferably substantially the same as that of the compressed spring 36, and the amount of compression of the spring 36 (the tightening amount of the adjusting nut 34) is simultaneously restricted by the spring restricting body 38. And the variation in the compression work can be eliminated. In other words, the adjustment nut 34 is tightened, and the lower end of the support piece 20b of the base portion 20 of the bus duct side structure portion is brought into contact with the upper end of the spring regulating body 38, whereby the tightening operation of the adjustment nut 34 is completed. Become.

  The bus duct side structural unit is fixed to the second channel members 14-1 and 14-2, and the lower end of the support bolt 26 is formed on the upper surface of the second channel members 14-1 and 14-2. The through nut (not shown) is inserted, and the mounting nut 30 is screwed from below and fixed. Finally, the adjustment nut 34 is loosened (moved upward in the figure), so that the springs of the auxiliary support portion 35 and the basic support portion 25 are released, and the bus duct 100 is pushed upward. In the attached drawings, the drawings showing the state where the bus duct side structural unit is attached to the floor side structural unit are all shown in a state where the adjustment nut 34 is not loosened, Eventually, the installation work is completed with this loosened.

  In a state where the adjustment nut 34 is loosened, the base member 20 fixed to the bus duct 100 can move upward by the amount of movement of the adjustment nut 34 being loosened. Therefore, when the bus duct 100 installed vertically expands and expands due to a temperature rise or the like, the expansion can be permitted by moving upward while the biasing force of the springs 32 and 36 is exerted.

  As described above, according to the bus duct support device of the present embodiment, a total of four support portions, that is, a pair of basic support portions 25 and a pair of auxiliary support portions 35, are installed. Since the basic support portion 25 that needs to perform the rotation operation 34 is disposed at a location distant from both sides, a sufficient space for the tool for the rotation operation is secured. Therefore, when the urging means is increased in accordance with the capacity of the bus duct 100, the support portions at positions close to each other by the addition of the auxiliary support portion 35 which does not require the subsequent nut adjustment. Installation is possible. Therefore, the size of the structure for installing the support portion including the base member 20 can be suppressed as small as possible.

  Further, for example, in the case of the bus duct 102 having a smaller capacity than the bus duct 100 of the first embodiment, it is possible to configure with a smaller number of support portions as shown in FIG. That is, a structure in which the basic support portions 25 are provided on both outer sides and only one auxiliary support portion 35 is provided in the center may be employed. In the case of this structure, since all members other than the auxiliary member 24 can be used in common, it is sufficient to manufacture the member other than the auxiliary member 24 first, and additionally manufacture only the auxiliary member 24 according to the capacity of the bus duct. As a result, manufacturing costs can be reduced. In other words, even if the number of springs changes, if the number of through holes in the second channel member 14 and the base member 20 does not change, only the position and number of the through holes in the auxiliary member 24 need be changed.

  Moreover, when installing only one basic support part 25, it is not necessary to provide it in the center part of the auxiliary member 24, for example, the arrangement | positioning of the state which removed the one of embodiment which has the two basic support parts 25 is carried out. The auxiliary member 24 may be the same as that of the first embodiment.

  Further, the arrangement of the auxiliary support portion 35 and the basic support portion 25 is not limited to the above embodiment, and may be an arrangement as shown in FIG. That is, as shown in FIG. 7A, the basic support portion 25 is installed in the center and the auxiliary support portions 35 are disposed on both sides and supported by three springs, as shown in FIG. 7B. A structure in which the auxiliary support portions 35 and the basic support portions 25 are alternately arranged and supported by four springs, as shown in FIG. 7C, the two basic support portions 25 are installed in the center and on both sides. A structure in which the auxiliary support portions 35 are arranged and supported by four springs, as shown in FIG. 7D, two auxiliary support portions 35 are arranged on both sides with the basic support portion 25 as the center. The structure supported by five springs can be applied as appropriate.

  As is clear from these structures, even when the number increases, the interval between the auxiliary support portion 35 and the auxiliary support portion 35 and the interval between the auxiliary support portion 35 and the basic support portion 25 are the same between the basic support portions 25. It is possible to set the distance smaller than the interval between adjacent ones. Therefore, as shown in FIG. 7D, when the number is large, the installation space can be remarkably reduced in size.

  FIG. 8 shows still another configuration example. As shown in FIG. 8 (A), the auxiliary member 24 does not necessarily have to be provided on the floor side structure part, and may be provided below the support piece 20b of the bus duct side structure part, and its shape is a collar part as shown in the figure. It is good also as a hat-shaped cross-sectional shape which has. Further, as shown in FIG. 8B, the auxiliary support portion 35 may be installed by a spring restricting body 38 fixed to the support piece 20b which is a bus duct side structure portion and a spring 36 whose position is restricted thereby. It is also possible to configure without providing the auxiliary member 24 as described above. Further, the auxiliary support portion 35 may be directly fixed to the second channel member 14 as shown in FIG. 8C, and the auxiliary member may be eliminated, and the basic support portion 25 is replaced as shown in FIG. 8D. Thus, only the support bolt 26 without a spring is used, that is, only the movement restriction function of the bus duct in the horizontal direction and the movement function of the adjusting nut 34 are used by the support bolt 26, and the urging means is only the auxiliary support portion 35. It is also possible. Further, as shown in FIG. 8E, the auxiliary support portion 35 may be fixed to the bus duct side structure portion and the second channel member. In this case, the spring restricting body 38 through which the spring 36 is inserted is provided. In order to allow the bus duct to extend, it is necessary to use a member such as elastic rubber. Further, as shown in FIG. 8 (F), an elastic member 37 such as an earthquake-resistant rubber can be provided as an urging means for the auxiliary support portion 35. In this case, the pin 39 and the like are inserted into and fixed to the second channel member 14, and an earthquake-resistant rubber is inserted into and fixed to the pin 39. In this way, the urging means used for the auxiliary support part 35 and the urging means used for the basic support part 25 can be made different in quality.

  Although each said embodiment has shown the example which installs the base member 20, the basic support 25, the auxiliary | assistant support part 35, etc. in the front and back of a bus duct, it is not restricted to this, These members are width | variety by the both sides | surfaces of a bus duct. It is also possible to install in the direction. FIG. 9 shows a configuration in which the base member 20, the basic support portion 25, the auxiliary support portion 35, and the like are installed on the side surface portion of the bus duct. According to this configuration, it is possible to secure a large number of support portions within the installation area of the bus duct.

  FIG. 10 shows a configuration in which bus ducts 104 and 106 of a plurality of systems having different capacities are installed side by side. FIG. 10 (A) is a front view and FIG. 10 (B) is a right side view. The distance between the second channel member 14 and the fixed-side surface of the small-sized bus duct 106 having a small capacity is larger than that in the case of the bus duct 104. Therefore, when using the common 2nd channel member 14, the structure of the bus duct side structure part which can ensure the intensity | strength of a bus duct side structure part is needed. In the present embodiment, for example, a reinforcing member 50 is provided to supplement the strength of the support piece 20b of the bus duct side structure.

  FIG. 11 shows a configuration example of such a reinforcing member 50. As shown in FIG. 6A, the base piece 50a is substantially the same as the width of the base member 20 of the bus duct side structure, and is formed narrower than the base piece 50a. The base piece 50a is fixed to the outer surface of the base member 20 by using bolts and nuts for fixing the base member 20 and the bus duct. The The horizontal piece 50 is fixed to the upper surface of the support piece 20 b of the base member 20 by a small bolt 52. With this structure, the base member 20 and the reinforcing member 50 form a triangular shape on the right side surface, and the reinforcing effect can be improved.

  Moreover, as shown to 11 (B), you may comprise the reinforcement member 54 as a pair of reinforcement members 54-1, 54-2, and contact | abuts to the outer surface of the base surface part 20a of the base member 20, and it is a front view. A base piece 54a that is substantially half-shaped, a horizontal piece 54b that is in contact with the upper surface of the support piece 20b at the lower end of the base piece 54a, and an inner end of each of the base piece 54a and the horizontal piece 54b and bent substantially at right angles to each other The reinforcing member may be composed of the reinforcing piece 54c to be used, and according to this configuration, the strength is increased as compared with the configuration of FIG. In addition, the attachment to the base member 20 is the same as that of the case of the said FIG. 11 (A).

  Further, as shown in FIG. 11C, the width of the reinforcing member 54 is made narrower than that of the reinforcing member 54 of FIG. 11B, and the positions of the reinforcing pieces 54c are separated from each other in the installed state. It is good also as a shape corresponding to the external shape of the base member 20, respectively, in a state where the ends are separated so as not to contact each other, and a balanced strength is secured and the material cost is saved as compared with the case of FIG. Is possible. The position of the reinforcing piece 54c may be changed depending on the number and position of the auxiliary support portion 35 and the basic support portion 25. For example, when the support portion using the spring is limited to a predetermined location, the spring is installed. By providing the reinforcing piece 54c in the same position as the position and the front view, accurate reinforcement is possible. Each of these reinforcing members 50 and 54 can be fixed to the base member 20 with a fixing tool such as a rivet.

  The guide member of the present invention may be a simple bar-shaped member other than the support bolt. In this case, a member that can be firmly fixed to a predetermined position of the bar-shaped member is used as the adjusting member. For example, a pin-shaped member may be inserted and fixed in a hole formed in the rod-shaped member.
