Description

  The present invention relates to a dry partition unit for partitioning an interior space of a building and a partition structure using the partition unit, and particularly to a partition unit excellent in workability, sound insulation and fire resistance, and a partition structure. .

  Conventionally, many RC and SRC wet structures have been constructed. However, in such a structure using concrete, formwork is essential, although it is excellent in sound insulation and fire resistance, and requires a great deal of cost. . For this reason, for the purpose of shortening the construction period and reducing costs, dry partition panels for partitioning adjacent living spaces are often used in apartment houses and hotels.

  The following is known as a dry partition structure. A structure is known in which metal studs (intermediate columns) are attached to upper and lower runners attached to upper and lower slab surfaces (ceiling surface, floor surface), and partition panels are attached to both surfaces thereof. As such a structure, Patent Document 1 describes a structure in which studs are alternately arranged on a wide runner laid on a ceiling surface and a floor surface, and a partition panel is attached thereto.

  Patent Document 2 describes a partition panel in which a hollow reinforcing portion is integrally formed on a flat plate. In the structure of Patent Document 3, a reinforcing material is fixed to the rear surface of the partition panel in advance, and is fixed to the upper and lower slabs with the reinforcing material side facing inward.

  Patent Document 4 describes a structure in which a reinforcing rib member is fixed to the back surface of a partition panel. In the structure of Patent Document 5, the reinforcing rib members are fixed to both ends of the rear surface of the partition panel, and the engaging portions are attached via the reinforcing rib members, so that the corner portions of the four partition panels facing each other are connected to each other. It is connected.

Japanese Utility Model Publication No. 60-162607 Japanese Utility Model Publication No. 54-049112 JP 60-005941 A Japanese Patent Application Laid-Open No. 07-207784 Japanese Patent Laid-Open No. 01-098809

  In the structure of Patent Document 1, it takes a lot of work to attach a metal stud, and the workability is low. For example, the structure of Patent Document 2 can be cited as an example in which the stud is not attached. However, since the partition panel in which the flat plate and the hollow reinforcing portion are integrally formed is used, the flat plate is the same as the reinforcing portion that requires strength. Cost increases due to the material.

  In the structures of Patent Document 3 and Patent Document 4, the partition panel and the reinforcing material are different from each other, and the partition panel may be warped due to the difference in expansion / contraction ratio. Therefore, there is a problem that a step is generated in the joint part and the joint part is opened. In order to prevent this phenomenon, there is a method of aligning the surfaces by striking a screw so as to straddle the joint, but the workability is lowered.

  In the structure of Patent Document 5 in which the corner portions of the four partition panels facing each other are connected to each other, the partition panel is relatively firmly fixed, and therefore, the step or opening of the joint portion is unlikely to occur. However, a lot of dedicated metal fittings are required and the amount of work on the construction site increases, resulting in a great cost and low workability.

  In view of the problems of the prior art, the present invention aims to provide a partition unit capable of obtaining good workability, reducing costs, and suppressing warping of the partition panel, and a partition structure using the partition unit. And

  The partition unit of the present invention includes a partition panel member that partitions the interior space of a building, a rib member that is fixed at a distance from the partition panel member along the back surface of the partition panel member, and reinforces the partition panel member; An elastic member sandwiched between the partition panel member and the rib member without being elastically deformed, and the force applied between the two members is alleviated by the elastic member.

  The partition unit of the present invention includes a partition panel member, a rib member that reinforces the partition panel member, and an elastic member that is sandwiched between the partition panel member and the rib member. Since it is not necessary to construct a metal stud in advance, it does not take time and workability is high. The partition panel member and the rib member can be made of different materials utilizing the respective material characteristics (strength required as the partition panel member, strength required as the rib member), and the cost is not increased. The elastic member fixed between the partition panel member and the rib member is sandwiched in a state where it is not elastically deformed, and the force applied between the two members is alleviated. Can be suppressed. Therefore, the work for preventing the occurrence of a step in the joint part and the phenomenon of opening the joint part becomes unnecessary, and the workability can be improved. Furthermore, since it is only necessary to attach a partition unit having a partition panel member and a rib member that reinforces the partition panel member to the partitioning portion, the amount of work at the construction site is reduced, and the cost can be reduced.

  The partition structure of the present invention is a plurality of partition units arranged laterally in the interior space of the building, a lower runner that is fixed to the floor and supports the lower part of the plurality of partition units, and is fixed to the ceiling surface. An upper runner that supports upper portions of the plurality of partition units, and each partition unit includes a partition panel member that partitions an interior space of a building, and a back surface of the partition panel member. A rib member that is fixed at a distance from the partition panel member and reinforces the partition panel member, and an elastic member that is sandwiched between the partition panel member and the rib member without being elastically deformed. Provided, and the force applied between the two members is alleviated by the elastic member.

  The partition unit provided in the partition structure of the present invention includes a partition panel member, a rib member that reinforces the partition panel member, and an elastic member that is sandwiched between the partition panel member and the rib member. Since it is not necessary to construct a metal stud in advance, it does not take time and workability is high. The partition panel member and the rib member can be made of different materials taking advantage of the respective material characteristics, and the cost is not increased. The elastic member fixed between the partition panel member and the rib member is sandwiched in a state where it is not elastically deformed, and the force applied between the two members is alleviated. Can be suppressed. Therefore, the work for preventing the occurrence of a step in the joint part and the phenomenon of opening the joint part becomes unnecessary, and the workability can be improved. Furthermore, since it is only necessary to attach a partition unit having a partition panel member and a rib member that reinforces it to the partitioning portion, the amount of work at the construction site is reduced, and the cost can be reduced.

  It is preferable to further include a correction plate that is attached so as to straddle the joint portion of the partition panel member of two partition units adjacent to each other among the plurality of partition units, and corrects the level difference of the joint portion. In this case, it is possible to prevent the occurrence of a step in the joint portion without taking a method of aligning the surfaces by hitting screws so as to straddle the joint portion.

  It is preferable that the upper end of the rib member of each partition unit and the ceiling surface are in a spaced state, and the lower end of the rib member and the floor surface are in a spaced state. In this case, the effect of suppressing vibration and heat propagation in adjacent living spaces can be further improved.

  It is preferable that the lower part of each partition unit is fixed to the lower runner, and the upper part of each partition unit is fitted into the upper runner. In this case, for example, the rib member can be easily attached simply by fitting into the upper runner, and the workability is remarkably improved. Thereby, cost can be reduced. Since the rib member is not completely fixed to the upper runner and the partition unit easily follows the displacement at the time of interlayer displacement, the earthquake resistance can be improved.

  Since it is not necessary to construct a metal stud in advance as in the present invention, the workability is high. The partition panel member and the rib member can be made of different materials taking advantage of the respective material characteristics, and the cost is not increased. Since the force applied between the partition panel member and the rib member is alleviated, the warp due to the difference in expansion / contraction ratio between the two members can be suppressed, and the work for preventing the warp becomes unnecessary, so that high workability is obtained. Since it is only necessary to attach a partition unit having a partition panel member and a rib member that reinforces it to the partitioning portion, the amount of work at the construction site is reduced, and the cost can be reduced. Furthermore, vibration and heat propagation in adjacent living spaces can be effectively suppressed, and a structure excellent in earthquake resistance can be obtained.

It is the partial cross section figure of the partition structure which attached the correction plate, and the perspective view of the correction plate. It is sectional drawing which shows the modification of a rib member. It is explanatory drawing in the case of using a cross-section U-shaped or C-shaped rib member. It is sectional drawing which shows the upper anchor of this embodiment, its periphery, and its modification. (A) is the perspective view which looked at the partition unit which concerns on other embodiment from the back surface side, (b) is a modification of a correction plate.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a partition unit 1 according to an embodiment of the present invention as viewed from the front side and the back side, and FIG. 2 is a partial cross-sectional view of the partition unit 1. The partition unit 1 of the present embodiment includes a partition panel member 2 that partitions the interior space of a building, a rib member 3 that reinforces the partition panel member 2, and an elastic member that is provided between the partition panel member 2 and the rib member 3. 4 and fixing means 5 for fixing them together.

  The partition panel member 2 of the present embodiment is a plate material formed in a rectangular shape in front view as illustrated. The shape and size of the partition panel member 2 are not limited, but are set to the shape and size assigned according to the size of the construction site. The material forming the partition panel member 2 is not limited as long as it is a non-combustible material that can be used as a building partition. For example, a cement-based flexible board having a thickness of about 3 to 15 mm, a gypsum board, a calcium silicate board, Fiberboard, particle board, wood-based plywood, hard fiberboard, steel plate and the like.

The specific gravity when an inorganic material is selected as the partition panel member 2 is preferably about 0.5 to 1.8 g / cm ³ . The maximum length of the partition panel member 2 when considering the floor height of a general apartment is about 3000 mm. When a small-sized building of this size is built, the specific gravity is 1.3 g / cm ³ or more. If you use the one you can avoid bending. Moreover, it can prevent that a weight becomes large too much by using the thing of specific gravity of 1.8 g / cm < ³ > or less.

Furthermore, in the case of an inorganic material, specific gravity of 1.5 to 1.7 g / cm ³ made with cement, calcium carbonate, and pulp as main components, bending strength of 17 to 23 N / cm ² , and expansion ratio of 0.05 to 0.00. A 12% cementitious flexible board is preferred. By using this compounding and physical properties, a high effect can be obtained for sound insulation, fire resistance, and warpage suppression. Furthermore, even when the gypsum board is attached with a staple or a screw using an air tucker or a screwing machine, the partition panel member 2 can be prevented from cracking and peeling on the back side.

  The rib member 3 is attached along the back surface 2a of the partition panel member 2 with a space from the partition panel member 2. One rib member 3 is attached along the longitudinal direction of both end portions of the partition panel member 2. The rib member 3 of the present embodiment is made of a thin steel material having a rectangular cross section. The rib member 3 is not limited to a steel material as long as it is nonflammable, and any material can be used as long as it can exert the reinforcing effect of the partition panel member 2 and can be self-supporting when used as a partition wall. The rib member 3 may be formed of the same material as that of the partition panel member 2.

  The elastic member 4 sandwiched between the partition panel member 2 and the rib member 3 has a sheet shape cut to a required dimension. The dimension and thickness of the elastic member 4 can be changed as appropriate. The elastic member 4 is sandwiched in a state where it is not elastically deformed, so that the force applied between the partition panel member 2 and the rib member 3 can be reduced. Thereby, the curvature by the difference in the expansion / contraction rate of the partition panel member 2 and the rib member 3 can be relieved.

  By reducing the force applied between the partition panel member 2 and the rib member 3, a difference in expansion / contraction ratio between the partition panel member 2 and the rib member 3 is allowed, and the warpage of the partition panel member 2 is suppressed. it can. Moreover, since the elastic member 4 is interposed between the partition panel member 2 and the rib member 3, not only a force relaxation effect but also a sound insulation effect can be remarkably improved.

  For this purpose, it is important to attach the elastic member 4 so as not to compress it. The interval between the partition panel member 2 and the rib member 3 so as not to elastically deform the elastic member 4 is the thickness of the elastic member 4. Therefore, the partition panel member 2 and the rib member 3 are attached with an interval corresponding to the thickness of the elastic member 4. As shown in the drawing, screwing is used for the fixing means 5 of the present embodiment for attaching the rib member 3 to the partition panel member 2 with the elastic member 4 being sandwiched.

  The fixing means 5 may be in any form such as a pin or a rivet as long as the spacing between the partition panel member 2 and the rib member 3 can be maintained in addition to screwing. When the rib member 3 is attached to the partition panel member 2, a hard packing material such as slate or PVC having the same thickness as the elastic member is placed between the rib member 3 and the partition panel member 2 in advance so as not to compress the elastic member 4. It can be removed after the attachment is completed.

  An adhesive may be used for the fixing means 5. In this case, an adhesive is applied to the front and back of the elastic member 4, and the partition panel member 2 and the elastic member 4, and the elastic member 4 and the rib member 3 are fixed in close contact with each other. If an adhesive is used, since the force which presses the elastic member 4 does not act, it can attach in the state which is not compressed reliably.

  Examples of the material for forming the elastic member 4 include natural rubber, synthetic rubber, styrene-butadiene rubber, butadiene rubber, chloroprene rubber, butyl rubber, nitrile rubber, ethylene propylene rubber, chlorosulfonated polyethylene rubber, acrylic rubber, urethane rubber, and silicon rubber. , Fluoro rubber, polysulfide rubber, foams thereof and the like.

  The hardness of the elastic member 4 is preferably 20 to 80, more preferably 30 to 60 with a type A durometer. By setting the hardness of the elastic member 4 to 20 or more, the elastic member 4 is hardly compressed during screwing, and high sound insulation can be obtained. By setting the hardness of the elastic member 4 to 80 or less, the vibration of sound transmitted to the elastic member 4 does not become too large, and high sound insulation can be maintained.

  Next, the partition structure 10 using the partition unit 1 will be described. 3 is a partial perspective view of the partition structure 10, FIG. 4 is a longitudinal sectional view of the partition structure 10, and FIG. 5 is a transverse sectional view of the partition structure 10. As shown in FIG. 4, the partition structure 10 of the present embodiment supports a plurality of partition units 1 arranged in the horizontal direction in the interior space of the building and the lower surface of the plurality of partition units 1 fixed to the floor t1. A lower runner 11 and an upper runner 12 fixed to the ceiling surface t2 and supporting the upper portions of the plurality of partition units 1 are provided. As shown in FIG. 5, the rib members 3 at both ends of each partition unit 1 are located close to the rib members 3 of the adjacent partition unit 1 so as to be along the longitudinal direction.

  The upper runner 12 and the lower runner 11 are both L-shaped steel materials that are long in the penetration direction of FIG. A pair of upper runners 12 are fixed to the ceiling surface t2 with concrete pins 13 so that the horizontal piece 12b faces the inner side with respect to the vertical piece 12a. A pair of lower runners 11 are fixed to the floor surface t1 with concrete pins 13 such that the horizontal pieces 11b face outward with respect to the vertical pieces 11a.

  The partition unit 1 is supported from the outside by the upper runner 12 and supported from the inside by the lower runner 11. A pair of partition units 1, 1 arranged in the horizontal direction are supported and attached to the upper runner 12 and the lower runner 11 with their back surfaces 2 a, 2 a facing each other.

  The upper end of the rib member 3 of the partition unit 1 and the ceiling surface t2 are in a spaced state, and the lower end of the rib member 3 and the floor surface t1 are in a spaced state. For this reason, the suppression effect of the vibration and heat propagation in adjacent living spaces can be further improved.

  The sound absorbing material / heat insulating material 14 is attached so as to be sandwiched between the partition units 1 and 1 with the back surfaces facing each other by pins (not shown) attached to the rib member 3. Rock wool or ceramic so as to cover the horizontal piece 12b of the upper runner 12 at a position spaced apart from the upper ceiling surface t2 of the rib member 3 inside the plurality of partition units 1 arranged in the lateral direction. A non-combustible material 15 such as wool is attached continuously in the lateral direction. A nonflammable material 15 such as rock wool or ceramic wool is also provided on the inner side of the plurality of partition units 1 arranged in the lateral direction at a position spaced from the lower floor surface t1 of the rib member 3 as in the upper side. Is attached.

  As shown in FIG. 4, the vertical piece 11 a of one (left side) lower runner 11 is screwed to the rib member 3 from the inside. The vertical piece 11a of the other (right) lower runner 11 is screwed to the rib member 3 from the outside. Such a screwing form is associated with the attaching process of the partition unit 1 and is appropriately changed. Sealing materials 16 are provided on the upper and lower sides of the partition panel member 2. A gypsum board 17 is attached to the surface 2b of the partition units 1 arranged in the horizontal direction, and serves as a wall surface of the room. In this way, the lower part of the partition unit 1 is fixed to the lower runner 11, and the upper part of the partition unit 1 is fitted into the upper runner 12 together with it.

  FIG. 6 is a partial cross-sectional view of the partition structure 10 to which the correction plate 18 is attached and a perspective view of the correction plate 18. The correction plate 18 is attached so as to straddle the inside of the joint portion m1 of the two partition panel members 2 adjacent to each other among the plurality of partition units 1 arranged in the horizontal direction. The correction plate 18 is made of a steel plate, and includes a base plate 19 and a fixed piece 20 formed by bending from the base plate 19.

  The base plate 19 is sandwiched between the partition panel member 2 and the rib member 3 so as to straddle the joint portion m <b> 1 of the adjacent partition panel member 2, and the fixing piece 20 is screwed to the rib member 3 together with the base plate 19. The location and number of the correction plates 18 are set as appropriate. By attaching the correction plate 18, the surface 2b of the adjacent partition panel member 2 comes to be aligned, and the occurrence of a step in the joint portion m1 can be prevented. Even when the partition panel member 2 is warped, the presence of the correction plate 18 causes a force to align the surfaces 2b between the adjacent partition panel members 2 and causes the warpage of the partition panel member 2. Can be prevented.

  The correction plate should just be a shape which can prevent the level | step difference of the joint part m1. For example, as shown in FIG. 10A, the correction plate 24 formed in an H shape in front view may be laid down and the elastic member 4 of the adjacent partition panel member 2 may be inserted into the two recesses 24a. In this shape, the concave portion 24a becomes a relief portion for positioning the elastic member 4, and the correction plate 24 does not move in the vertical direction. There is no fixed piece for attaching to the rib member 3, and the screwing step is not necessary. As described above, the correction plate may have any shape as long as the base plate to be corrected can be held between the partition panel member 2 and the rib member 3.

  The partition structure 10 using the partition unit 1 is constructed as follows, for example. First, the upper runner 12 and the lower runner 11 on one side (left side in FIG. 4) are respectively attached to the ceiling surface t2 and the floor surface t1. The vertical piece 12a of the upper runner 12 is inserted into the gap between the upper part of the partition panel member 2 on one side and the upper part of the rib member 3 so as to insert the partition unit 1 from an oblique direction. If insertion is confirmed, the lower part of the partition panel member 2 will be addressed to the lower runner 11, and the partition unit 1 will be made upright on the floor surface t1. The partition panel member 2 is screwed from the inside of the vertical piece 11a of the lower runner 11.

  An incombustible material 15 is filled in the upper gap of the partition unit 1 so as to cover the horizontal piece 12b of the upper runner 12. Similarly, the nonflammable material 15 is filled also in the lower gap of the partition unit 1 so as to cover the horizontal piece 11 b of the lower runner 11. Then, a pin (not shown) for fixing the sound absorbing / insulating material 14 is attached to the rib member 3 of the partition unit 1, and the non-combustible material 15 is fixed with the pin.

  Thereafter, the upper runner 12 and the lower runner 11 on one side (right side in FIG. 4) and the partition unit 1 are attached in the same procedure as that on the right side. A plurality of partition units 1 arranged in the horizontal direction are attached so as to face each other and screwed from the room side, and then a gypsum board 17 is attached to the surface 2b of the partition panel member 2 and further wallpaper is applied to finish. This construction procedure shows an example, and can be arbitrarily set according to the form of the partition unit 1 and the partition structure 10.

  The partition unit 1 constituting the partition structure 10 of the present embodiment includes a partition panel member 2, a rib member 3 that reinforces the partition panel member 2, and an elastic member that is sandwiched between the partition panel member 2 and the rib member 3. 4 is provided. Since it is not necessary to construct a metal stud in advance, it does not take time and workability is high. The partition panel member 2 and the rib member 3 can be made of different materials utilizing their respective material characteristics (strength required as the partition panel member 2 and strength required as the rib member 3), and the cost is not increased.

  The elastic member 4 sandwiched between the partition panel member 2 and the rib member 3 is sandwiched in a state where it is not elastically deformed, and the force applied between the members 2 and 3 is alleviated. 3 can suppress warpage due to the difference in expansion / contraction ratio. Therefore, work for preventing a phenomenon that a large level difference is generated in the joint part m1 or the joint part m1 is opened becomes unnecessary, and workability can be improved. Furthermore, since it is only necessary to attach the partition unit 1 having the partition panel member 2 and the rib member 3 that reinforces the partition panel member 2 to the partition portion, the amount of work at the construction site is reduced and the cost can be reduced.

  Further, the rib member 3 of the partition unit 1 is not completely fixed to the upper runner 12, and the upper portion of the partition unit 1 is simply fitted into the upper runner 12. It can be easily installed just by fitting, and the workability is greatly improved. Thereby, cost can be reduced. Since the rib member 3 is not completely fixed to the upper runner 12 and the partition unit 1 easily follows the displacement at the time of interlayer displacement, the earthquake resistance can be improved.

  This invention is not limited to the said embodiment, The shape of a partition panel member and a rib member, a dimension, an attachment method, etc. can be suitably changed according to the specification which partitions off the internal space of a building. FIG. 7 is a sectional view showing a modification of the rib member 3. As shown in the figure, the rib member 3 may have a U-shaped cross section, an L shape, a C shape, a circular shape, a triangular shape, or a polygonal shape.

  In the case of using a U-shaped or C-shaped rib member, as shown in FIG. 8, the rib members 3 are arranged on the partition panel member 2 so that the openings 3a and 3a of the two rib members 3 and 3 face each other. 3 is attached. And it is good also as a structure which attaches the heat insulating material 14 between the two rib members 3 and 3. FIG. In this case, since the trouble of attaching the heat insulating material 14 at the site can be omitted, the workability can be further improved.

  The attachment position of the rib member can be arbitrarily set as long as the correction plate can be attached. The shape of the upper runner may be, for example, a U-shaped upper runner 21 as shown in the central view of FIG. 9, or an L-shaped angle 22 may be used as the upper anchor as shown in the right view of FIG. The shape of the lower anchor is the same. In the above embodiment, the rib member is attached in the vertical direction. However, as shown in FIG. 10B, the rib member 26 is formed longer, and this is directed obliquely with respect to the partition panel member 2. It may be attached. If the rib member 26 is attached in an oblique direction, the number of attachments is reduced and the workability is improved.

  The partition unit according to the present invention and the partition structure using the partition unit can be changed within the technical scope described in the claims. The other members provided as necessary in the partition structure using the partition unit may have any form as long as the effects of the present invention are not impaired.
