Description

  The present invention relates to a wall panel used as a load-bearing wall in a building such as a steel house.

  Conventionally, (1) as shown in FIG. 6, a plurality of horizontal bars 22 are provided in parallel in the vertical direction so as to be accommodated in the frame body 2 in order to stop bending and twisting deformation of the vertical frame member 3. A load bearing wall provided with a face material is known (see, for example, Patent Document 1). The length of the vertical frame is about 3 m, which is almost the height of one building.

  (2) Instead of a horizontal beam, a steel plate face material is provided with a raised portion by bending out of plane of the steel plate, and in order to integrate it with the frame body, the end of the face material is bent into a U-shape and the frame body It is also known to be integrated with (see, for example, Patent Document 2).

(3) In the cross section of the concrete pillar / beam, the studs are fixed to the four sides of the face plate made of a 9 mm to 22 mm thick steel plate, and the four ends of the face material together with the studs are fixed. Seismic wall using folded plates with horizontal joints (folding bars in the horizontal direction) to embed and eliminate vertical force and bending moment acting on the wall and to apply pure shearing force to the face material Is known (see, for example, Patent Document 3). In Patent Document 3, the folded plate is used as a horizontal joint in order to eliminate the vertical force and bending moment acting on the wall and to apply a pure shear force to the face material, which should be solved by the present invention. The challenges are different.

  In the case of (1), since a plurality of horizontal rails are used, there are problems that the number of members increases, the manufacturing cost of the wall panel increases, and the wall panel becomes expensive.

  In the case of the above (2), it is bulky when the face materials are stacked, and a large number of face materials cannot be transported, so that the transport efficiency is reduced, the transport cost is increased, and the cost of the wall panel is increased. In addition, there is a problem in that the stress transmission efficiency is lowered due to the out-of-plane bending portion of the steel plate in the stress transmission path from the frame to the face material.

  An object of the present invention is to provide a wall panel that can solve the above-described problems, has a simple structure, is inexpensive, and has excellent deformation performance.

In order to solve the above-mentioned problem advantageously, in the wall panel of the first invention, a face material is fixed by screwing to at least one surface of a frame body comprising a vertical frame material and a horizontal frame material made of thin lightweight steel. In the wall panel, the face material is composed of a thin folded plate having an upper flange surface, a lower flange surface substantially parallel to the upper flange surface, and a web surface connecting the upper flange surface and the lower flange surface. The upper flange surface is separated from the plane formed by the vertical frame member and the side surface of the horizontal frame member, and the lower flange surface is the vertical frame member or the horizontal frame at both longitudinal ends thereof. It is characterized in that it is in surface contact with the side surface of the material, is fixed to the vertical frame material and the horizontal frame material by screwing, and no reinforcing horizontal rail is provided inside the frame body.
Further, in the second invention, in the wall panel of the first invention, the folded plates of the folded plate are arranged so as to be orthogonal to the vertical frame member, and both end portions in the longitudinal direction of the lower flange of the folded plate are respectively the vertical frames. It is characterized by being screwed to the material.
In the third aspect of the invention, in the wall panel of the first aspect of the invention, the folding lines of the folded plate are arranged so as to be orthogonal to the lateral frame material, and both end portions in the longitudinal direction of the lower flange of the folded plate are respectively horizontal frames. It is characterized by being screwed to the material.
In the fourth invention, in the wall panel of the first through third aspects, a plurality of sheets of folded plate the surface material has a seam overlap in a direction orthogonal to the folding bars foldable plate, the overlapped seam one place per And at least one lower flange surface and the web surfaces on both sides thereof are overlapped, and screw plates are used for joining the folded plates in the lap joint, and only the face materials are used per one lap joint. A screw in which the number of screws that are screwed is fixed to the vertical frame material or the horizontal frame material only in the vertical frame material or the horizontal frame material in a direction parallel to the fold line. It is an integer greater than or equal to the number that can be obtained by multiplying the number by the value obtained by dividing the plate thickness of the frame member by the plate thickness of the face member .
In the fifth invention, in the wall panel according to the first to third inventions, the face material is composed of a plurality of folded plates having overlapping seams in a direction orthogonal to the folding lines of the folded plates, and the per one overlapping seam. The at least one lower flange surface and the web surfaces on both sides thereof are overlapped, and welding of the folded plates at the lap joint is performed by welding.
Although Patent Document 3 does not have a horizontal beam and uses a folded plate with a horizontal joint as the face material, the column / beam and the folded plate are not eccentric, and the material of the column / beam is concrete. There is no need to solve the problem of the invention to solve the problem of twisting and bending deformation of the vertical frame material. A feature of the present invention is that a folded plate is used for suppressing twisting and bending deformation of a vertical frame that occurs in a wall panel in which a face member is screwed to one side of the frame member. Therefore, the folded plate of the vertical joint is not a solving means of Patent Document 3, but is a solving means in the present invention, and the technical idea of the present invention and Patent Document 3 are clearly different.

According to the first invention, in the wall panel in which the face material is fixed by screwing to at least one surface of the frame body including the vertical frame material and the horizontal frame material made of the thin plate lightweight section steel, the face material made of the thin folded plate is provided. Since it is fixed by screwing and there is no reinforcing horizontal beam inside the frame body, the vertical frame material is prevented from being twisted or restrained from bending deformation by the face material made of thin folded plates. The effect can be exhibited with an inexpensive wall panel with a simple structure. In addition, by this, it can prevent that stress concentrates on a specific screw, and can implement | achieve the bearing wall excellent in the deformation capacity by preventing the rapid proof stress deterioration by local destruction of a face material.
According to the second invention, the folding lines of the folded plate are arranged so as to be orthogonal to the vertical frame material, and both ends of the lower flange longitudinal direction of the folded plate are screwed to each vertical frame material, The vertical frame member can be reliably prevented from twisting, and the same effect as in the case of claim 1 can be obtained.
According to the third invention, since the folding lines of the folded plate are arranged in parallel to the vertical frame material, the bending deformation of the vertical frame material is suppressed, and the same effect as in the case of claim 1 is obtained. Can do.
According to the fourth invention, when there are a plurality of face materials constituting the wall panel and an overlap seam is required, it is possible to configure the seam by overlapping the end portions without performing special processing on the end portions of the face material. As a result, an inexpensive wall panel can be realized. In addition, when screwed, it is possible to realize a wall panel that is cheaper and has better deformation performance than welded joints and caulking joints, etc., and by increasing the number of screws at the lap joint between the face materials thinner than the frame material A high-strength wall panel can be realized.

  Next, the present invention will be described in detail based on the illustrated embodiment.

  First, one form of the frame 2 used in the wall panels 1A, 1B, 1C of the embodiment of the present invention will be described with reference to FIG. An upper horizontal frame member 5 disposed over the upper end portion of each vertical frame member 3 and joined by a screw fixing fixture 4 such as a tapping screw, and a lower end portion of each vertical frame member 3. A rectangular frame 2 is constituted by a lower horizontal frame member 6 joined by a screwing fixing tool 4 such as a tapping screw. In the present invention, there is no reinforcing horizontal beam between the vertical frame members 3. In the present invention, the reinforcing horizontal beam is caused to act by a folded plate described later to prevent the vertical frame member 3 from being twisted.

  The vertical frame member 3 is a vertical frame member 3 formed by a pair of thin light-weight grooved steels 7 abutting back to back at the web 8 and integrated by a screwing fixing tool 4 such as a tapping screw. In addition, the upper horizontal frame member 5, the lower horizontal frame member 6, and the vertical frame member 3 are all made of thin lightweight steel.

  As said thin plate light weight shape steel, in order to fix the face material 1 which consists of a folded plate to the frame 2 with the screwing fixing tools 4, such as a tapping screw, board thickness 0.8mm-2.3mm, Preferably board thickness 1 A shape steel produced by roll forming a thin steel plate of 0.0 mm to 1.6 mm, for example, a shape steel such as a grooved steel with a lip or a grooved steel.

  FIG. 2 shows one form of the cross section of the folded plate 9 used in the wall panels 1A, 1B, 1C of the embodiment of the present invention, and a thin steel plate having a thickness of 1.0 mm or less thinner than the frame material. Folded by roll forming, the upper flange 10 and the web 11 on both sides of the upper flange 10 connected to the upper flange 10 and inclined at a gentle inclination, and the lower flange 12 connected to the upper flange 10 and parallel to the upper flange 10 were bent. It is the folded plate 9 manufactured in the cross-sectional trapezoid square waveform. By inclining the web 11, the amount of face material used can be reduced, and the wall panel 1 can be made lighter and cheaper.

FIG. 1 shows a wall panel 1A according to a first embodiment of the present invention. A folded plate 9 having a trapezoidal square corrugated section as shown in FIG. 2 is provided on one side of a frame 2 shown in FIG. The folding line in the folded plate is arranged so as to be orthogonal to the vertical frame member 3, and the end of the lower flange 12 in the longitudinal direction is fixed to each vertical frame member 3 by a screw fixing fixture 4 such as a tapping screw, A wall panel 1A is configured.
Further, the lower flange 12 of the end portion in the vertical direction of the folded plate 9 is brought into contact with the flanges of the upper horizontal frame member 5 and the lower horizontal frame member 6, respectively, and a tapping screw or the like is provided at intervals in the left-right direction. It is fixed by a screw fixing fixture 4.

  In this embodiment, since the folding line of the folded plate 9 is arranged at right angles to the vertical frame member 3, the sectional second moment per the same width of the folded plate is shown in FIG. 1 (c) from the horizontal section shown in FIG. The vertical cross section shown in b) is enhanced, whereby the torsional deformation of the vertical frame member 3 is effectively suppressed. Further, since the buckling strength in the longitudinal direction of the lower flange is increased, bending deformation in which the vertical frame members 3 are attracted to each other by the horizontal force acting on the wall panel 1A is suppressed.

  FIG. 3 shows a wall panel 1B according to the second embodiment of the present invention. A folded plate 9 having a trapezoidal square corrugated section as shown in FIG. 2 is provided on one side of the frame 2 shown in FIG. The folding lines in the folded plate are arranged so as to be orthogonal to the horizontal frame members 5 and 6, and the end portions in the longitudinal direction of the lower flange 12 are attached to the horizontal frame members 5 and 6 by screw fixing fixtures 4 such as tapping screws. The wall panel 1B is configured by being fixed.

  In this embodiment, since the folding line of the folding plate 9 is arranged in parallel to the vertical frame member 3, the folding plate 9 resists bending in the direction perpendicular to the folding line, and thereby the bending deformation of the vertical frame member 3 is effective. Is suppressed.

  FIG. 4 shows a wall panel 20 for comparison with the wall panels 1A and 1B of the present invention, in which a face material of a flat sheet steel plate 21 is arranged on one side of the frame 2 shown in FIG. The peripheral edge portion of the flat thin steel plate 21 is a wall panel 20 fixed to the horizontal frame members 5 and 6 and the vertical frame member 3 by a screwing fixture 4 such as a tapping screw.

  A wall panel 20 of a comparative example as shown in FIG. 4 is manufactured, and a load Q (kN) −rotation angle R (R) when a horizontal force (load Q) is applied to cause the wall panel to undergo shear deformation δ (mm). = Δ / H) curve is shown in FIG.

The test result of the wall panel 20 of the comparative example shown in FIG. 4 is shown in FIG. 7, and the rotation angle R is 15 × 10 ⁻³ rad in the case of the wall panel 20 of the flat sheet steel 21 of the comparative example. It can be seen that it has dropped rapidly from the vicinity. This is because, as shown in FIG. 8, stress is concentrated on a specific screw due to bending deformation and torsional deformation of the vertical frame, and local bearing material failure occurs.

  In addition, the dimension of the frame 2 in the said wall panel is height H = 2730mm, and horizontal width W = 910mm. Moreover, the plate | board thickness dimension of the flat thin steel plate 21 is 0.6 mm, the vertical frame material of the wall panel 1 is 1.6 mm, and the screw has stopped the face material and the frame material with the pitch of 150 mm.

Frame material and face material for the wall panel 1A of the first embodiment as shown in FIG. 1, the wall panel 1B of the second embodiment as shown in FIG. 3, and the wall panel 20 of the comparative example as shown in FIG. FIGS. 9 to 11 show distribution diagrams obtained by applying the black and white portions where the principal stress of the face material at a horizontal force of 18 kN is 30 N / mm 2 or more, obtained from the FEM analysis results of the wall panel having the same plate thickness and screw pitch. Show.
In FIGS. 9 to 11, as the area of the black portion is larger, the stress is dispersed, and the stress is not concentrated on a specific screw, so that the local bearing material does not break down and exhibits excellent seismic performance. I can say that.
From FIG. 9, in the wall panel 1A of the first embodiment, the principal stress on the face material is distributed almost evenly, and the wall panel 1B of the second embodiment and the corner panel connecting the diagonals in the order of the wall panel 20 of the comparative example. It can be seen that the stress is concentrated in the part, and it can be easily estimated that the seismic performance is degraded.
In addition, the dimension of the frame 2 in each said wall panel is height H = 2700mm on the same conditions, and is horizontal width W = 900mm. Moreover, the plate | board thickness dimension of the flat thin steel plate 21 is 0.6 mm, the vertical frame material of each wall panel 1 is 1.6 mm, about a folded plate, the upper and lower flange width is 18 mm, the web width is 19.5 mm, The valley pitch and the screw pitch are set to 75 mm, and are fixed by the screw fixing fixture 4.

  When practicing the present invention, as the folded plate 9 as the face material, the width c (valley width) of the lower flange 12 in FIG. 2 needs to be larger than the screw head diameter, so the width of the upper flange 10 is 10 mm to 250 mm. It is preferable to use a (width) of 0 mm to 50 mm and a width b of the inclined web 11 of 10 mm to 100 mm. Further, it is preferable that the height from the lower flange 12 to the upper flange 10 is greater than the plate thickness, which increases the bending rigidity of the folded plate 9 in the direction of the folding line, but if it is increased, the amount of steel sheet used increases. Since it is not economical, about 5-25 mm is preferable. Further, as the inclination angle θ of the web 11, if the inclination angle θ is increased, the amount of use of the steel sheet is increased and it is not economical, and if the inclination angle θ is small, improvement in rigidity cannot be efficiently expected. As long as there is no angle, the inclination angle θ may be about 10 to 60 degrees. Note that the face material may be an arc corrugated plate as long as the screw head does not cause damage that is a problem in terms of yield strength. In addition, the lower flange 12 may be fixed with two screws. In that case, it is desirable to bring the lower flange 12 close to the inclined webs 11 at both ends in order to suppress the out-of-plane bending deformation of the lower flange 12 (screws are separated from each other). Also, since the screw head is arranged on the face material side when joining the face material and the frame material, if the face material is a flat plate, a screw head with a thin screw head diameter must be used. However, when the lower flange 12 is screwed with a folded plate, the screw head height is moderately limited by the height of the folded plate, so a screw with a larger screw head diameter or a washer with a larger outer diameter can be used. Strength, rigidity, and deformation performance of the joint between the frame material and the face material can be increased.

  The wall panel 1A of the first embodiment (FIGS. 1 and 9), the wall panel 1B of the second embodiment (FIGS. 3 and 10), and the wall panel 20 of the comparative example (FIGS. 4 and 11) are sequentially seismic resistant. A supplementary explanation will be given of the deterioration in performance. Since the folded plate transmits stress by the shear deformation of the flat plate surrounded by the folds and the end faces, when the folded plate is arranged as shown in FIG. The wall height direction is almost uniform stress, and local bearing failure is unlikely to occur. Therefore, in the wall panel 1A using the face material made of the folded plate having a horizontal joint shape as shown in FIG. 1 (FIG. 9), the stress is uniformly distributed over the entire face material, but as shown in FIG. 4 (FIG. 11). In the wall panel 20 using a flat plate made of such a flat plate, a large stress is generated on the diagonal of the flat plate, and it can be seen that local destruction of the flat plate occurs. In addition, although it is thought that the face material which consists of a folding plate of the vertical joint form shown in FIG. 3 (FIG. 10) is also transmitted by the shear stress, the length of the mountain (the wall in FIG. 10 is compared with the width of the mountain). Since the panel width (height of the wall panel in FIG. 11) is large, a stress transmission loss due to buckling occurs, and it can be easily estimated that the local deformation performance is larger than the horizontal joint.

In order to verify the first and second embodiments of the present invention, a performance confirmation experiment was performed using the loading apparatus shown in FIG. The wall panel 28A is joined to the force jig 27B with a hole-down hardware 29 joined to the lower part (joined at the position of the panel end at the bottom of FIG. 13), and the upper part is a loading beam attached to the force jig 27A. The load was loaded by pushing and pulling the force jack 25 attached to the loading beam. The measurement items are the loading load Q and the rotation angle R, the loading load is the jack load, and the rotation angle is the difference between the displacement gauges 26A and 26B (both measured at a position 100 mm from the end of the panel) divided by the distance between the displacement gauges. It was assumed.
The loaded test body is a conventional type in which the cross rail 22 is eliminated in the form in which the intermediate vertical frame member 3a is provided at the center between the vertical frame members 3, and the steel plate 21 without unevenness is used as the face member as shown in FIG. Wall panel 28A, a folded plate 9 having a trapezoidal square corrugated cross-section as shown in FIG. 15, and a wall panel 28B in which the folding line in the folded plate is arranged perpendicular to the vertical frame member 3, and FIG. The folded plate 9 having a trapezoidal square wave shape as shown in the figure is a wall panel 28 </ b> C arranged so that the folding line in the folded plate is orthogonal to the horizontal frame members 5 and 6. As shown in FIG. 12D, the wall panel 28B overlaps the four folded plates 9 at the end joints 23 and fastens them with the screwing fasteners 4, and the intermediate vertical frame member 3a has the folded plate 9 A folded plate 9 having a trapezoidal square corrugated cross section is arranged such that the folding line in the folded plate is orthogonal to the vertical frame member 3 in a form in which the intermediate portion is fixed with a screw fixing fixture 4 in the same manner as the vertical frame member 3. It is a wall panel.
The dimensions of the frame 2 in each of the wall panels 28A to 28C are the same, and the height H = 2730 mm and the width W = 910 mm as shown in FIG. The crosspiece 22 is eliminated in the form provided with the intermediate vertical frame member 3a. Further, the thickness of the flat thin steel plate 21 is 0.6 mm, the vertical frame material of each wall panel 1 is 1.6 mm, and the folded plate 9 has a vertical flange width of 18 mm as shown in FIG. The width was 20.1 mm, the valley pitch and the screw pitch were 76.2 mm, and they were fixed by the screw fixing tool 4. The peak height was 15 mm, and the screw used was a nominal diameter of 4.8 mm.

  FIG. 19 shows a conventional wall panel 28A and a wall panel 28B of the present invention, among the envelopes of the load-deformation relationship obtained from loading. From FIG. 19, the load (elastic limit load) at which the rigidity sharply decreases is about 4 k compared to 28 A, in which the wall panel 28 B exceeds 25 kN, even though the wall panel 28 A is about 6 kN. The wall panel 28B has excellent seismic performance compared to the wall panel 28A because the maximum strength of the wall panel 28B is about twice that of the wall panel 28A. Was confirmed.

FIG. 20 shows a conventional wall panel 28A and a wall panel 28C of the present invention, among the envelopes of the load-deformation relationship obtained from loading. From FIG. 20, the wall panel 28C according to the present invention has a higher load at a small deformation angle level of about 10 × 10 ⁻³ rad than the conventional wall panel 28A, and the deformation angle after the maximum proof stress is exhibited. It was confirmed that the wall panel 28C of the present invention has excellent seismic performance as compared with the conventional wall panel 28A because the proof stress is moderate and rich in deformation performance.

  FIG. 12 shows a wall panel 1C according to a third embodiment of the present invention. The folding line direction of the folded plate 9 is the same as that of FIG. 1, but the face material is composed of two folded plates 9 and is a surface. There is a seam 23 between the materials. At this time, the deformation in the direction perpendicular to the folding line can be suppressed by overlapping the two web surfaces sandwiching the lower flange 12 of the folded plate 9, so that the deformation in the direction parallel to the bending line can be prevented by the screwing fixture 4. Stop it. However, the yield strength of the screw joint is approximately proportional to the thickness of the plate when the plate is thinner than the screw diameter. If the plate thickness of the face material is smaller than the frame material plate thickness, screw it at a fixed interval in the direction parallel to the crease, and the screw joint at the position where there is no frame material (position between the face materials only) Yield is low. Therefore, in order to increase the yield strength, it is desirable to increase the number of screws at the joint, and the magnification is desirably about a value obtained by dividing the frame material plate thickness by the face material plate thickness. For example, if the frame material plate thickness is 1.2 mm and the face material plate thickness is 0.6 mm, the number of screws is desirably doubled or more. Instead of increasing the number of screws, the number of screws may be increased by placing a steel plate or shape steel having a thickness equal to or greater than the thickness of the frame under the face material and screwing. , 6 and the wall panel (not shown) in which the face material is divided may be screwed together with the seam at the vertical beam position. Moreover, if joints are jointly performed in the factory in advance, the joints need not be limited to screw joints, and may be spot welded at the same pitch as the thread joints or may be continuous welding. In addition, if deformation performance is required rather than proof stress, the wall panel may be deformed with a seam deformation without increasing the number of screws, and a viscoelastic body or the like is sandwiched between folded plates to provide damping performance. It may be improved.

The third embodiment of the present invention is an improvement plan for the joint specifications of the joints between the face materials. In order to verify the performance, a performance confirmation experiment was performed using the apparatus shown in FIG.
The loaded test body is provided with an intermediate vertical frame member 3a at the center between the vertical frame members 3 and the cross rail 22 is eliminated, and the five folded plates 9 are end joints as shown in FIG. 12 (d). 23. The intermediate vertical frame member 3a has a trapezoidal square wave-shaped cross section in the form in which the intermediate portion of the folded plate 9 is fixed with the screw fixing member 4 in the same manner as the vertical frame member 3. The folded plate 9 is a wall panel arranged such that the folding line in the folded plate is orthogonal to the vertical frame member 3, and two bodies, a wall panel 31A as shown in FIG. 21 and a wall panel 31B as shown in FIG. It was. Note that the dimensions of the frame 2 in the two wall panels are the same under the conditions of height H = 2730 mm and lateral width W = 910 mm as shown in FIG. Moreover, the vertical frame material of each wall panel 1 is 1.6 mm, and as for a folded plate, as shown in FIG. 23, the upper flange width is 35 mm, the lower flange width is 56 mm, the web width is 17 mm, the mountain pitch is 125 mm, and the mountain height is A screw having a nominal diameter of 4.8 mm was used. The difference between the wall panel 31A and the wall panel 31B is the joint specification of the folded plates without the frame material (horizontal crosspiece) under the joint between the face materials. The wall panel 31A is screwed at one joint. The folded plates without the frame material are fixed with four screws per one joint. The wall panel 31B has a configuration in which the number of screws is increased to 12 which is three times the value (1.6 / 0.6 = 2.66) obtained by dividing the frame material thickness by the folded plate thickness.

  FIG. 24 shows the envelopes of the two load-deformation relationships obtained from the loading. As shown in FIG. 24, the wall panel 31B according to the third embodiment of the present invention has a load whose rigidity is remarkably reduced as compared with the wall panel 31A in which the joint between the face members and the screw pitch of the face member and the frame member are the same. It can be said to be a specification that is high and suitable for cases where high proof stress is required. Further, it was found that the joint 23 has a stiffening effect because there is little change in the cross-sectional shape of the folded plate compared to the position where there is no overlap because the face materials overlap.

  Note that the present invention is described on the assumption that a folded plate is arranged on one side of the frame member. However, for example, when the wall thickness is moderately limited or a large proof stress is required, both sides of the frame member are described. In this case, the vertical frame is not twisted, so that it can be easily estimated that it exhibits a performance that is at least twice that of the wall in which the folded plate is arranged on one side. In addition, the present invention is characterized in that there are no horizontal rails. For example, when there is a limit to the wall thickness in application to an actual property, the folding plate may be lowered and the horizontal rails may be used in combination. The technical idea is the same as using folded plates as a means to reduce the cross rail.
