Description

  The present invention relates to a structural wall constructed to increase the rigidity and yield strength of a structure.

  For example, as a general reinforcement structure for existing structures that have been judged to be insufficient in earthquake resistance, an in-situ reinforced concrete seismic wall or steel brace is installed in the inner space of an existing beam column structure formed of columns and beams. Seismic reinforcement was performed by arranging etc.

  However, the reinforced concrete seismic wall has the problems that the inner space of the beam column frame is blocked by the wall, which deteriorates aesthetics and color and makes it impossible to perform necessary piping including ducts. Was. In addition, the seismic reinforcement by the steel brace has the problem that the degree of freedom in design is limited by the arrangement of the steel frame, although lighting and piping are possible.

  Therefore, in Patent Document 1, as shown in FIG. 15 (a), for the purpose of improving the aesthetics and the daylighting property, the steel plate 102 fixed in the inner space of the beam column 110 and the vertical and horizontal directions are provided. A seismic reinforcing wall 101 having an opening 103 formed in the steel plate 102 in alignment is proposed.

  Further, as shown in FIG. 15 (b), the applicant of the present invention forms a unit 202 of the intermediate column 204 and the intermediate beam 204 that can be divided into the inner space of the beam column structure 210 of the existing building in a lattice shape by bolt joining. The seismic reinforcement wall 201 which arranges and reinforced the earthquake resistance of the existing building is disclosed, and has been put into practical use. Thereby, while ensuring lighting nature, carrying in and installation of the reinforcement wall to the existing building is enabled by carrying in the divided member (refer to patent documents 2).

  However, the seismic reinforcement wall 101 described in Patent Document 1 is a lattice-shaped member formed by providing an opening 103 in a single steel plate 102 having the same shape as the hollow cross section of the beam column structure 110. Depending on the layout of the existing building, it may not be possible to carry in. Moreover, since this seismic reinforcement wall 101 is difficult to construct by human power due to its weight and size, it needs to be constructed through a construction machine. Therefore, it also has a problem that it is limited to buildings that can secure a space in which construction machines can be arranged.

  On the other hand, in the invention described in Patent Document 2, by assembling the divided units 202 in a lattice shape, it is possible to carry in and install members without being limited to the floor plan and scale of an existing building, and also ensure lighting performance. However, although it is possible to reinforce, since the intermediate columns 203 and the intermediate beams 204, which are structural materials, are arranged in the frame surface, the thickness of each member is thick, which may impair visibility and aesthetics. . In addition, each unit 202 (intermediate column 203 and intermediate beam 204) made of H-shaped steel or the like is divided, but it is heavy and may be difficult to convey and install by manpower, affecting the workability. There was a case where

  The present invention solves the above-described problems, can be easily constructed by human power, and has excellent mechanical properties such as rigidity and proof stress, and also has aesthetics, daylighting, ventilation, etc. The problem is to propose a structural wall that is also functionally superior.

In order to solve the above problems, the structural wall of the present invention includes a lattice-shaped wall body having a plurality of openings, and a plate-like member installed in at least a part of the plurality of openings, The wall body is a lattice-like member composed of vertical members and cross members arranged at arbitrary intervals, and the plate-like member has a fixing member formed on four sides. The lattice member is formed by connecting a plurality of divided pieces each composed of a vertical piece and a horizontal piece, and the divided pieces are the vertical pieces of the adjacent divided pieces or It is connected by the fixing member arrange | positioned so that the said horizontal piece may be straddled .

  In such a structural wall, since the wall main body is configured in a lattice shape, an external force acting on the structure in which the structural wall is constructed is appropriately dispersed, so that the proof stress and rigidity of the structure are increased. In addition, since the plate-like member is disposed in a predetermined opening among the plurality of openings of the lattice-shaped wall main body, a structural wall having higher mechanical strength such as proof stress and rigidity is constructed. In addition, since this structural wall can be formed with a plurality of openings, it is excellent in daylighting, enables piping, etc., and has excellent design freedom. ing. And since this structural wall is formed by connecting a plurality of divided pieces, if the weight of each divided piece is set to such a level that it can be handled by human power (for example, 30 kg or less), a separate machine or the like is required. Therefore, it is possible to construct a structural wall by human power, and it is possible to construct a structural wall in a place where it is difficult to secure a work space, such as an existing building, which is preferable. Furthermore, since this structural wall is finely subdivided into a plurality of divided pieces, the member carry-in route is not limited.

  Here, in this specification, the wall main body is configured by connecting divided pieces and arranged as a main material of the structural wall for the purpose of increasing the rigidity and proof strength of the structure by its strength. It is a material. Further, the plate-like member is a plate-like member having a predetermined strength, and the rigidity and proof strength of the structure in which the structural wall is disposed by being appropriately disposed in a predetermined opening of the structural wall. A member that makes it possible to increase

In addition, the structural wall is configured such that the wall main body (lattice-like member) is configured by combining vertical members and cross members in a lattice shape, so that the external force acting on the structure in which the structural wall is constructed can be Dispersion to the cross member increases the yield strength and rigidity of the structure. In addition, since the adjacent divided pieces are connected by a fixing member disposed so as to straddle the vertical pieces or the horizontal pieces, a lattice-like member made of continuous vertical members and horizontal members is formed, and is excellent. Demonstrates high yield strength and rigidity. Moreover, since the fixing member is formed on the four sides of the plate-like member, the divided pieces adjacent to the opening where the plate-like member is arranged are connected together with the arrangement of the plate-like member, so that the workability is excellent. Yes.

  The said structure wall WHEREIN: The said division | segmentation piece may be comprised with the board | plate material arrange | positioned so that a fore edge surface may face the out-of-plane direction of the said grid | lattice-like member. With such a configuration, when the structural wall is viewed from the front, a linear lattice is formed. For this reason, this structural wall does not block the view and is excellent in aesthetics.

  Further, in the structural wall, if the plate-like member is arranged in a checkered pattern with respect to the plurality of openings, the divided pieces are connected without requiring a separate fixing member, and the plate-like member is a structural wall. In this case, a truss-like resistance mechanism is formed and a mechanically advantageous structure is obtained. For this reason, it is possible to increase the horizontal strength during an earthquake or a strong wind.

  Moreover, if the fixing member is fixed to the divided piece by bonding the contact surface with the divided piece with an adhesive on the structural wall, the work is easy and early construction is possible. Moreover, even if it is the construction work of the structural wall in the building in service and a fire equipment etc. cannot be used, construction of a structural wall is attained. Further, since there are no protrusions such as nuts and bolt heads, the design is excellent. In addition, as an adhesive agent, what is necessary is just to select suitably from well-known adhesive agents suitable for metal adhesion | attachment, such as an epoxy type and an acrylic type, for example.

  Further, in the structural wall, the fixed plate material may be fixed to the divided piece by plug welding through a plurality of welding holes formed in the fixed plate material or the divided piece. In other words, because the number and shape of the weld holes formed according to the expected shearing force at the joint are fixed by plug welding, it is easier to construct the structural wall than normal welding where the entire periphery of the fixed plate material is welded. Can be constructed, which is preferable.

  Further, if the divided pieces are formed in a cross shape, a T shape or an L shape in the structural wall, the shape of each divided piece is small and lightweight, so that the handling is easy and the work efficiency is improved. Is possible.

  According to the present invention, a structure that can be easily constructed by human power, has excellent mechanical properties such as rigidity and proof stress, and has excellent functions such as aesthetics, daylighting, and ventilation. It became possible to provide walls.

  Preferred embodiments of the present invention will be described with reference to the drawings. In the description, the same reference numerals are used for the same elements, and duplicate descriptions are omitted.

The adhesive used for bonding the divided piece 11 and the fixed plate material 21 is excellent in adhesion between steel members, and is peeled off or sheared by an external force assumed to act on the structural wall 1. In this embodiment, an epoxy adhesive or an acrylic adhesive is used. Moreover, the adhesion between the divided pieces 11 and 11 and the fixing plate material 21 is not necessarily the entire surface adhesion, and may be partial adhesion as long as the strength necessary for the connection between the divided pieces 11 can be expressed. Needless to say.

  In the present embodiment, a gap is formed between the divided pieces 11, but the presence or absence of a gap between the divided pieces 11 is not limited.

  Next, a method for constructing the structural wall 1 according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 5A, the construction wall 1 is first constructed by laying a grout material 40 in a space corresponding to the lower end of the structural wall 1 in the inner space of the beam column frame 5. Then, the lowermost divided piece 11 (L-shaped piece 11 b and T-shaped piece 11 c) is disposed on the upper surface of the grout material 40.

  Next, the lowermost plate-like member 20 is disposed, and the contact surface of the fixing member 21 with the divided piece 11 is adhered to the divided piece 11 with the adhesive 30 (see FIG. 5B).

  When the lowermost plate-like member 20 is disposed, the second-stage divided piece 11 (the cross-shaped piece 11a and the T-shaped piece 11c) is disposed as shown in FIG. At this time, the newly arranged divided piece 11 and the existing plate-like member 20 are adhered to each other. When the arrangement of the second-stage divided pieces 11 is completed, the second-stage plate-like members 20, 20,.

  Similarly, the lattice-shaped member 10 is completed by arrange | positioning the division | segmentation piece 11 and the plate-shaped member 20 in order from the bottom. When the lattice member 10 is completed, the grout material 40 is filled between the upper surface and side surfaces of the lattice member 10 and the beam column frame 5 (see FIG. 5D). The grout material 40 may be appropriately selected from known grout materials, and is not limited. However, in the present embodiment, the grout material 40 is usually located at locations corresponding to the side surface and the lower end of the structural wall 1. A mortar 41 is used, and a non-shrink mortar 42 is used at a location corresponding to the upper end of the structural wall 1. By using the non-shrink mortar 42 at the joint with the beam column frame 5 at the upper end of the structural wall 1, the formation of a gap due to the shrinkage of the grout material 40 is prevented.

  As described above, according to the structural wall 1 according to the first embodiment, the lattice member 10 is configured by the divided pieces 11, 11,... Divided so as to have a weight and a shape that can be handled by human power. Therefore, even in the case where only a limited space can be secured as a carry-in route, such as an existing building, members can be carried in, so the strength of any structure is not limited to the installation location. And the rigidity can be increased.

  Further, in addition to the divided pieces 11, the plate-like member 20 is also formed in a weight and shape that can be handled by human power, so that the structural wall 1 can be easily constructed only by human power and has excellent workability. Yes. Further, since various construction machines and equipment that have been conventionally required for constructing the structural wall can be omitted, the cost can be greatly reduced.

  Since the structural wall 1 is composed of the plate-like member 20 and the lattice-like member 10 arranged at appropriate positions, the structural wall 1 is not affected by an earthquake or a strong wind as in the case of a conventional earthquake-resistant wall or brace material. It is possible to construct a structure having sufficient proof stress and rigidity against the stress acting on the arranged structure. Moreover, since the low yield point steel material is used as the plate-shaped member 20, the plate-shaped member 20 absorbs the external force which acts on the structure wall 1, and the proof stress of a structure is strengthened.

  Since the plate-like member 20 according to the first embodiment has four corners cut away and the defect portion 22 is formed, when stress is applied to the structural wall 1, the stress and strain are one point (plate-like member). 20), the energy is absorbed effectively because it is dispersed in the lattice member 10 (vertical piece 12 or horizontal piece 13).

Further, the arrangement of the plate-like member 20 is preferable because lighting, ventilation, or aesthetic design can be freely designed.
Further, if a plate material made of glass fiber reinforced plastic, grating, punching metal, or the like is used as the plate-like member 20, the degree of freedom in design increases, which is preferable.

Further, the arrangement pitch and the number of the plate-like members 70 are not limited, and may be appropriately set according to the required strength of the structural wall 6 and the shape of the lattice-like member 60.

  As shown in FIGS. 9 and 10, the lattice-like member 60 has a plurality of divided pieces 61, 61,... , And is formed by connecting via a high-strength bolt 65.

  As shown in FIG. 10, the split piece 61 according to the present embodiment is configured by a rectangular cylindrical member 62 having a substantially square cross section. The cylindrical member 62 is configured by cutting a steel pipe having a square section in a predetermined length, and the structural wall 6 is configured such that the opening surface of the cylindrical member 62 faces in the front-rear direction of the structural wall 6. It is configured by connecting. Here, the member thickness, the shape width, and the like of the cylindrical member 62 are not limited, and may be set as appropriate according to the shape dimension of the structural wall 6 and the stress acting on the structural wall 6. Further, the production of the cylindrical member 62 is not limited to the method of cutting the square steel pipe, and may be appropriately performed by known means such as press molding or welding assembly.

  As shown in FIG. 10, the cylindrical member 62 has bolt holes 66 through which the high-strength bolts 65 are inserted on the side that comes into contact with another adjacent divided piece 61 (cylindrical member 62). Individually formed. The number and shape of the bolt holes 66 are not limited, and may be set as appropriate according to the dimensions and number of the high-strength bolts 65. Needless to say, the connection between the divided pieces 61 is not limited to that by the high-strength bolt 65, and may be appropriately selected from known methods. Furthermore, the number of the high-strength bolts 65 is not limited, and may be set as appropriate from the strength of the high-strength bolts 65 and the stress acting on the structural wall 6.

  As shown in FIG. 11A, the split piece 61 has nothing arranged in the inner space of the cylindrical member 62, and the split piece 61a in which the opening 63 is opened, and in FIG. As shown, there is a split piece 61 b in which the inner space of the cylindrical member 62 is closed by the plate-like member 70. The structural wall 6 according to the present embodiment is configured in a checkered pattern by alternately arranging the divided pieces 61a where the plate-like member 70 is not arranged and the divided pieces 61b where the plate-like member 70 is arranged. (See FIG. 9A).

The plate-like member 70 is a steel plate having the same shape as the hollow cross section of the cylindrical member 62, and the entire circumference is substantially at the center in the length direction of the inner surface of the cylindrical member 62 (left-right direction in FIG. 9B).

In addition, the fixing method of the plate-shaped member 70 is not limited to the method by welding, What is necessary is just to perform by a well-known method suitably. Moreover, what is necessary is just to set suitably the material, plate | board thickness, etc. which comprise the plate-shaped member 70, and although it is not limited in this embodiment, the plate | board thickness uses the low yield point steel material (LYP) of 9 mm. And

  Further, as shown in FIGS. 10 and 11 (c), the split piece 61c arranged on the side portion of the structural wall 6 (position that contacts the beam column frame 5) has a side (surface) on the beam column frame 5 side. ) Are provided with six studs 64, 64,. Further, as shown in FIGS. 10 and 11 (d), the split piece 61d arranged at the corner of the structural wall 6 has six studs on each side (surface) on the column 2 and beam 3 and 4 side. 64, 64,...

  As shown in FIG. 10, the split pieces 61, 61 are connected to each other by placing the high-strength bolts 65 in the bolt holes 66, 66 formed in the adjacent split pieces 61, 61 after the split pieces 61 are arranged at predetermined positions. This is done by inserting and tightening.

  The structural wall 6 and the beam column frame 5 are joined by filling the gap between the lattice member 60 and the beam column frame 5 with a grout material 40. In addition, since the studs 64, 64,... Protrude from the periphery of the lattice-like member 60, the joining property is excellent. Note that the method of joining the structural wall 6 and the beam column frame 5 is not limited to the above-described method, and may be performed by, for example, the anchor method similarly to the method described in the third embodiment. .

  As described above, according to the structural wall 6 according to the fifth embodiment, the lattice member 60 is configured by the divided pieces 61, 61,... Divided so as to have a weight and a shape that can be handled by human power. Therefore, even in the case where only a limited space can be secured as a carry-in route, such as an existing building, members can be carried in, so the strength of any structure is not limited to the installation location. And the rigidity can be increased.

  Further, in addition to the split piece 61, the plate-like member 70 is also formed in a weight and shape that can be handled by human power, so that the structural wall 6 can be easily constructed only by human power and has excellent workability. Yes. Further, since various construction machines and equipment that have been conventionally required for constructing the structural wall can be omitted, the cost can be greatly reduced.

Moreover, since the division piece 61 which comprises the grid | lattice-like member 60 is manufactured by cut | disconnecting a square steel pipe by fixed length, the same shape and the same quality can be formed cheaply.
Moreover, since each cylindrical member 62 is formed in the same shape, it is difficult to create a gap between the divided pieces when stacked vertically and horizontally. In addition, when the manufacturing system of the square steel pipe is poor and adjacent orthogonal planes are not truly right angles, it is possible to pile up without forming a gap by alternately inverting the upper and lower and left and right of the adjacent cylindrical members 62 It becomes.

Further, since the split pieces 61 are joined together via the high-strength bolts 65, on-site welding is unnecessary, and the structural wall 6 is easily constructed even in an existing structure in which the use of fire is restricted. I can. Moreover, since equipment necessary for welding can be omitted, construction is possible even when the work space is limited.
Further, by joining the plate-like member 70 to the divided piece 61 in advance, it is possible to easily eliminate the trouble of joining at the site, and it is easy to construct in an existing structure where on-site welding is unnecessary and the use of fire is restricted. The wall 6 can be constructed.

Moreover, since the low yield point steel is used as the plate-like member 70, the plate-like member 70 absorbs an external force acting on the structural wall 6 and exhibits a function as a hysteresis damper.
Since the structural wall 6 alternately arranges the divided pieces 61b in which the plate-like members 70 are arranged and the divided pieces 61a in which the plate-like members 70 are not arranged in a checkered pattern, a truss mechanism is formed by the plate-like members 70. The mechanical performance as a seismic wall is ensured.

  Since the structural wall 6 is composed of the plate-like member 70 and the lattice-like member 60 arranged at appropriate positions, the structural wall 6 can be used during an earthquake or a strong wind as in the case of a conventional earthquake-resistant wall or brace material. It is possible to construct a structure having sufficient proof stress and rigidity against the stress acting on the arranged structure.

  Since the structural wall 6 is joined to the beam column frame 5 by an anchorless method, it is possible to reduce noise and vibration associated with the construction such as anchor installation on the existing beam column frame 5.

Further, the arrangement of the plate-like member 70 is preferable because lighting, ventilation, or aesthetic design can be freely designed. Further, the structural wall 6 can be used as a display shelf or a lighting fixture can be fitted.
Further, if a plate material made of glass fiber reinforced plastic, grating, punching metal or the like is used as the plate-like member 70, the degree of freedom in design increases, which is preferable.

In the fifth embodiment, the plate-like members 70 are arranged in a checkered pattern, but the openings of the lattice-like members 61 are formed as in the structural wall 6a shown in FIGS. 12 (a) and 12 (b). It is good also as a structure which arrange | positions the plate-shaped member 70 in all the parts 63. FIG. According to this structural wall 6a, it is excellent in workability compared with the conventional reinforced concrete wall, and there is no curing period, and it is possible to perform construction in a short period of time. In addition, since it can be constructed in a dry manner, the site is not soiled. Compared to conventional steel plate walls, steel braces, etc., work can be done by loading and assembling the split pieces 61 that can be transported by manpower. However, it is excellent in that it can be applied to existing structures that are limited.
Further, in the case of constructing the structural wall 6a that closes the inner surface of the beam column frame 5, even if some openings for piping, ducts, etc. may be necessary, the divided pieces at that location It is possible to easily form the opening 63 simply by changing 61 to the divided piece 61a in which the plate-like member 70 is not installed.

Moreover, as shown to Fig.13 (a), the structure wall 6b in which the window opening 67 was formed by the arrangement | positioning of the division | segmentation piece 61 is possible. Note that the number and shape of the window openings 67 in the structural wall 6a are not limited.
Furthermore, as shown in FIG. 13 (b), it is possible to construct the structural wall 6c in which the entrance / exit 68 is formed by providing a sweep opening and arranging it in a gate shape. In addition, the number and shape dimensions of the entrance / exit 68 in the structural wall 6b are not limited.
