Description

  The present invention is attached to a steel material (roof purlin) used as a framework of a roof, and easily and surely holds building material plates such as a ceiling plate and a decorative plate between molds, and easily attaches the building material plates. The present invention relates to a building material plate holding member and a building material plate holding structure.

As various steel-framed construction structures, multiple roof purlins made of C-shaped steel are fixed in parallel to the eaves on top of rafters such as H-shaped steel that are arranged with a gradient, and the roof basement is located above these roof purlins. A structure in which a material is laid and attached is known.
On the other hand, especially in a large-sized building, since the grooved steel and C-shaped steel constituting the roof purlin are exposed on the indoor side, the appearance is deteriorated. For this reason, various proposals have been made for the purpose of improving the appearance of the attic or for the purpose of improving the heat insulation.

For example, Patent Document 1 proposes a building material holding member including a first holding member fixed to a grooved steel and a decorative holder attached to the first holding member. In addition, since the makeup | decoration holder in this patent document 1 is an essential member, it is a member which should be called a 2nd holding member.
The first holding member in this proposal is configured to include a first clamping piece that contacts the upper surface of the first building material, and the decorative holder contacts the lower surface of the first building material and causes the first building material to move to the first building material. A second sandwiching piece that presses in the thickness direction toward the one sandwiching piece; and a third sandwiching piece that sandwiches the end of the second building material inserted into the opening of the channel steel from the thickness direction. Yes.

Japanese Patent No. 5561650

However, in the structure of Patent Document 1, the “building material” is arranged in such a manner that “the end of the first building material 11a is arranged toward the outer periphery of the web 2a, and the second building material 11b is disposed in the opening 2d of the roof purlin 2A. However, from FIG. 4 and the like, it is assumed that the end portion of the building material 11a has a size that is short enough not to interfere with the locking portion 12c. However, since the right end of the building material 11a that is arranged obliquely from below and inserted and rotated without interference is not supported anywhere, the building material 11a is likely to drop out before the decorative holder 13 is attached. It was a thing.
In particular, the grooved steel (C-type steel) shown in Patent Document 1 is a member in which an error is easily generated in the arrangement pitch. If the mounting pitch is narrow, the locking portion interferes and the building material does not enter. If it is too wide, the gap becomes larger, which has a problem that the operator has to hold down until the decorative cover is attached. Moreover, in the case of such restraining work, the placement of the building materials and the attachment of the decorative holder are performed alternately, and the work efficiency is extremely poor.
Further, when the makeup holder is made longer than the building material, the makeup holder cannot be attached until all the building materials for that length are arranged, and the workability becomes worse.

  Therefore, the present invention is mounted on a steel material (roof purlin) used as a framework of the roof, and easily and reliably holds building material plates such as a ceiling plate and a decorative plate between the formwork, and mounting of the building material plates is also easy. It aims at proposing the building material board holding member and building material board holding structure which can be performed.

The present invention has been proposed in view of the above, and is a building material plate holding member that can be attached to a purlin made of a plurality of mold steels having a lower flange to hold the building material plates between the mold steels. A mounting portion that is attached to the lower flange, and a holding portion that is located above the mounting portion and that has a groove-like portion that opens laterally. The holding portion includes a groove-like portion. Proposing a building material plate holding member (hereinafter simply referred to as a holding member) characterized in that it can be expanded against the elasticity and the grooved portion can be tilted toward the mold steel against the elasticity. It is.
In addition, although the holding member of the present invention is a member that wraps one end portion of the building material plate, the other end portion may be supported in abutting manner on an adjacent steel plate, or the holding member itself You may make it provide the support part which supports the other edge part in abutting form (henceforth the case where it has this structure is called a 2nd aspect).

  Further, according to the present invention, the holding member wraps one end portion of the building material plate, and the other end portion of the building material plate includes a vertical piece portion along the shape steel, and a lower end of the vertical piece portion. The present invention also proposes a building material board holding structure (hereinafter simply referred to as a holding structure) characterized in that it is supported in an abutting manner by an auxiliary member having a flange and a supporting piece portion extending in the opposite direction.

  The present invention also proposes a holding structure in which a decorative cover capable of covering the lower flange of the steel plate and the mounting portion of the holding member from the lower side is attached in the holding structure.

  The holding member of the present invention can easily and surely hold the end of a building material plate such as a ceiling material or a decorative board by the elasticity of the groove-shaped portion, and the groove-shaped portion tilts toward the steel plate side. The position of the building material plate in the length direction can also be adjusted. For this reason, the other end of the building material plate may be supported in a butt-like manner, for example, on adjacent steel plates.

  Further, the holding member may be provided with a support portion that supports the other end portion of the adjacent building material plate with the mold steel interposed therebetween, and in the second aspect, only the holding member is provided. The end portions of the two building material plates adjacent to each other with the mold steel interposed therebetween can be held and supported in a butt shape, and a holding structure can be constructed between the mold steels. In this case, at least another member such as the decorative holder in Patent Document 1 is not indispensable, and the building material plate can be easily and reliably obtained without causing the falling of the building material plate or poor work efficiency. Can be supported in a butted manner.

  Furthermore, the holding structure of the present invention that supports the other end portion of the building material board with the auxiliary member in abutting manner is the auxiliary member that holds the other side of the building material board in the abutting shape. However, each can be independently attached to the mold steel, and since the attachment is not restricted to each other, the building material plate can be held between the mold steels very easily and reliably.

  Further, when a decorative cover that can cover the lower flange of the steel plate and the mounting portion of the holding member from the lower side is attached, the decorative cover itself has an action of supporting the building material plate as in Patent Document 1. Therefore, the building material board does not fall off before the decorative cover is disposed, and the attachment of the holding member is not restricted.

  The holding member of the present invention is a member that can be attached to a purlin made of a plurality of mold steels having a lower flange and can hold an end of a building material plate, and an attachment part that is attached to the lower flange of the mold steel; A holding portion provided with a groove-like portion that is located above the attachment portion and that opens laterally. The holding portion is capable of expanding the groove-like portion against elasticity. In addition, the groove-shaped portion can be tilted toward the mold steel against resistance.

  In addition, you may extend the support part which supports the other edge part of an adjacent building material board on both sides of a shape steel, but the holding member of this 2nd aspect is only this member, and it sandwiches a shape steel. The holding structure can be formed by holding and supporting the ends of two adjacent building material plates in a butted manner. This support part extends in a direction opposite to the lower flange of the steel plate (exactly, in a direction opposite to the direction in which the lower flange extends).

  The holding structure of the present invention using the holding member includes one end portion of the building material plate held by the holding member, and the other end portion of the building material plate is connected to the vertical piece portion along the shape steel and the vertical portion. It is characterized in that it is supported in an abutting manner by an auxiliary member comprising a supporting piece portion extending in the opposite direction from the lower flange of the steel plate from the lower end of the piece portion.

  Further, in these holding structures, it is desirable to attach a decorative cover that can cover the lower flange of the steel plate and the mounting portion of the holding member from below.

  Hereinafter, the holding member of the present invention, the auxiliary member used in the present invention, the decorative cover, the steel plate as the attachment target thereof, and the building material plate as the retention target will be described.

  As described above, the holding member of the present invention is configured to include the attachment portion and the holding portion including the groove-like portion, and holds one end portion of the building material board. The holding member may have a long shape continuous in the length direction of the steel plate, but a plurality of pieces formed in a piece shape may be attached at appropriate intervals as in the illustrated embodiment described later. As described above, the holding member and the holding member are different in whether or not they are provided with a support portion.

  The attachment portion is attached to the lower flange of the mold steel, and the shape may be selected according to the specification of the lower flange of the mold steel to be used. For example, if the mold steel is H-shaped steel, I-shaped steel, groove-shaped steel, Z-shaped steel, L-shaped steel, etc., the lower flange has a simple horizontal piece shape, so that the mounting portion has a folded shape that engages the tip of the horizontal piece shape. In the case of having an upward piece (lip) at the tip of the lower flange such as C-type steel (= lip groove type steel) or lip Z-type steel, this mounting portion is a U-shape that engages with the upward piece. What is necessary is just to form in a shape.

The holding portion is provided with a groove-like portion that is located above the attachment portion and is open on the side, and a part (upper piece) of the attachment portion is a portion of the attachment portion as in the illustrated embodiment described later. It may also serve as a part of the holding portion (the lower piece of the groove-like portion).
In addition, although "clamping" in this holding part means holding one end part of a building material board, it is limited to the mode which always presses the end part from the up-and-down direction. Instead, the end portion is not always press-contacted, but includes an aspect in which the end portion is pressed when some load is applied.

The groove-shaped portion is a lateral groove shape that is located above the mounting portion and opens laterally, and can be expanded against elasticity (the interval between the upper piece and the lower piece can be expanded), Moreover, any shape can be used as long as it can be tilted toward the mold steel against the elasticity. For example, it may have a square shape such as a U-shape, or a horizontal groove shape formed of a curved surface such as a horizontal U-shape. It may be.
As described above, it is needless to say that the “holding” in the present invention is preferably a mode in which pressure contact is always considered in consideration of mounting stability, that is, in that case, in the upper piece that forms this groove-shaped portion. It is desirable to provide a contact piece that always contacts (pressure contact) the upper surface of the building material plate. The shape of the abutment piece is not limited, and even if the lower piece is in pressure contact with the upper surface of the building material plate, a part of the lower piece protrudes downward and comes into contact with the upper surface of the building material plate. It may be a thing, or the tip of a lower piece etc. may protrude below, and may contact the upper surface of a building material board.

A guide piece that bends upward and expands the distance from the lower piece as in the illustrated embodiment described later may be provided at the tip of the groove-like portion. It plays the role of guiding into the shape part.
In addition, this guide piece may serve also as the site | part (pressing piece) which presses an edge part when the above-mentioned some load is applied, and may be provided separately from the said site | part.

  Here, as described above, the support portion that supports the other end portion of the adjacent building material plates with the mold steel interposed therebetween may be provided on the holding member (the holding member of the second aspect) or a separate member. (Auxiliary member) may be provided. For comparison (distinguishing), the former support portion is used as a support portion, while the latter support portion is used as a support piece portion.

  The support portion is provided on the holding member of the second aspect, and extends in the direction opposite to the lower flange of the steel plate as described above, and the support height of two adjacent building material plates is If the lengths are substantially the same, for example, a flange shape or a substantially L shape may be used, and the specific configuration is not particularly limited.

  The auxiliary member is used together with a holding member on which the support portion is not provided, and is configured to support the other end portion of the building material plate in abutting manner as described above, and a vertical piece portion along the shape steel, The support piece portion extends in the opposite direction from the lower flange of the steel plate from the lower end of the vertical piece portion. The auxiliary member may have a long shape that is continuous in the length direction of the steel plate as in the case of the holding member, but a plurality of piece-like members may be attached as in the illustrated embodiment described later.

  As described above, the vertical piece portion is along the shape steel. Specifically, the vertical piece portion is formed on the web for H-shape steel, I-shape steel, groove-shape steel, C-shape steel (= lip-groove shape steel), Z-shape steel, lip Z-shape steel, and the like. Along with the angle steel (L steel), it is along the vertical part. An attachment part may be extended as appropriate to the vertical piece part, or a fixing tool such as a screw may be driven in as an attachment part to the mold steel.

  As described above, the support piece portion extends from the lower end of the vertical piece portion in the opposite direction to the lower flange of the steel plate, and the support height of two adjacent building material plates is substantially the same as the support portion. As long as they are the same, for example, a flange shape or a substantially L shape may be used, and the specific configuration is not particularly limited.

The decorative cover has a decorative surface portion that covers the lower flange of the steel plate and the mounting portion of the holding member from the lower side, and is formed in a long shape that is continuous in the length direction of the steel plate.
The decorative cover may be configured to assist the attachment of the attachment portion of the holding member and the lower flange of the steel mold, or assist the attachment of the auxiliary member and the steel mold (including indirect assistance). A) may be provided.

  The shape steel to which the holding member is to be attached may be any steel having a lower flange, specifically, an H-shaped steel having a lower flange on both the left and right sides, an I-shaped steel, and a groove having a lower flange on only one of the left and right. Corresponding to mold steel, Z-shaped steel, L-shaped steel, C-shaped steel having an upward piece at the end of the lower flange (= lip groove shaped steel), lip Z-shaped steel, and the like. In addition, you may make it connect and use these steel shapes back to back.

Among these, since the H-shaped steel and the I-shaped steel have lower flanges on both the left and right sides, the lower flange can support the other end of the adjacent building material plate with the mold steel interposed therebetween. The support piece is not required, and the auxiliary member itself is not required.
In other steel molds, the lower flange is provided on only one of the left and right sides, and therefore, the main flange is formed by arranging the lower flanges of all the steel molds so as to extend in the same direction.
It should be noted that when two mold steels having a lower flange on only one of the left and right sides are connected in a back-to-back manner, the lower flange extends on both the left and right sides, which is the same as when using the H-shaped steel or I-shaped steel. is there. This steel may be newly installed, but it may be used as a part of a building. Especially when C steel is used, most C steels have lower flanges. Are arranged so as to extend in the same direction, but there are places where they are attached in a back-to-back manner.

In other words, when H-shaped steel or I-shaped steel having lower flanges on both the left and right sides is used as the mold steel (the same applies when two mold steels are combined in the back-to-back shape described above), only the holding member that does not include the support portion is used. Can support all building material boards.
When using a grooved steel, a Z-shaped steel, an L-shaped steel, a C-shaped steel (= lip grooved steel), a lip Z-shaped steel having a lower flange only on one of the other left and right, use a holding member provided with the support part, Or all the building-material boards can be supported by using together and using the auxiliary member provided with the said support piece part in addition to the said holding member.

The building material board refers to a ceiling board, a decorative board, etc., and is a board shape arranged so as to be bridged between adjacent steel plates, and may be substantially flat or curved, and its end If it has the intensity | strength (hardness) which can maintain a support structure continuously by supporting, it will not specifically limit the material.
Further, the end portion of the building board is not limited to the one cut from the surface in a substantially vertical shape. For example, the end portion may be formed in a step shape with the lower surface side cut out.

  As described above, in the present invention, only the lower steel flange is provided for the steel mold, but the steel mold selected from the groove steel, the Z steel, the L steel, the C steel, and the lip Z steel provided with the lower flange on only one of the left and right sides. In the case of limitation, the end of the building material plate is attached to a purlin made of a plurality of steel molds selected from groove steel, Z steel, L steel, C steel, and lip Z steel, each having a lower flange on only one of the left and right sides. A holding member that can be held between the molds and a holding structure are provided.

  In addition, although repeatedly described, “clamping” in the present invention is not limited to an aspect in which the end portion of the building material plate is always pressed against from above and below, and an aspect in which the end portion is pressed when some load is applied. As long as the other end of the adjacent building material plate is sandwiched between the steel plates, the other end may be supported in principle. Needless to say, it is desirable to include a structure for pressing from the side.

  A holding member 1 according to the first embodiment of the present invention shown in FIG. 1 includes an attachment portion 11 attached to a lower flange 41 of a steel plate 4 and a groove-like portion that is located above the attachment portion 11 and that opens laterally. The holding portion 12 includes a holding portion 12, and the holding portion 12 can expand the groove-like portion 13 against elasticity as shown on the left side of FIG. 2, and The groove-like portion 13 can tilt toward the steel plate 4 against elasticity.

  First, members other than the holding member 1 shown in FIG. 1 (the steel plate 4, the decorative cover material 3, the auxiliary member 2, and the building material plate 5) will be described. First, the steel plate 4 shown in FIG. The lower flange 41, which is a C-shaped steel having flanges 43 and 41 at both ends (upper and lower ends) of 42, and has an upward piece 411 at the tip, extends to the right in the drawing.

  Moreover, the decorative cover 3 shown in FIGS. 1D to 1F is a member that covers the lower flange 41 of the steel plate 4 and the attachment portion 11 of the holding member 1 from the lower side, and has a decorative surface 31 that is a bottom surface. It is a long material with a substantially bowl-shaped cross section that rises from side to side. One side surface (right side surface) 32 whose tip (upper end) is bent also serves to assist the attachment of the attachment portion 11 to the lower flange 41 along the outside of the attachment portion 11 of the holding member 1. A plurality of raised portions 331 for attaching the auxiliary member 2 are provided outside the side surface (left side surface) 33.

Further, the auxiliary member 2 shown in FIGS. 1 (g) to 1 (i) is back-to-back with the vertical piece portion 21 along the web 42 of the steel plate 4 and the lower flange 41 of the steel plate 4 from the lower end of the vertical piece portion 21. And an extending L-shaped support piece 22. That is, the upper end of the support piece 22 is formed so that the upper end of the upward piece 411 formed at the tip of the lower flange 41 of the steel plate 4 is substantially the same height.
Further, the upper end of the vertical piece portion 21 is provided with a hooking piece 23 that is hooked to the upper flange 43 of the steel plate 4, and in the middle of its height, a plurality of rectangular cut empty portions 211 are formed, The pressing pieces 212 that protrude outward are formed at a plurality of locations by the cut and raised by the cutting.

FIG. 1 (j) shows a state in which the holding member 1 is not intentionally arranged, and a raised portion 331 formed on the other side surface 33 of the decorative cover 3 is the auxiliary member 2. It is shown that indirectly assisting the attachment of the auxiliary member 2 to the steel plate 4 because it is engaged with the notch empty space 211.
However, in this state, the end portion 51x of the building material plate 5 is only supported by the lower flange 41 (upward piece 411) of the steel plate 4 and the upper end of the support piece portion 22 of the auxiliary member 2, respectively. Is low.
Moreover, the building material board 5 shown in the figure is a board-like ceiling material arranged so as to be bridged between the adjacent steel plates 4, 4, and the end portion 51x located on one side is: It is cut from the surface in a substantially vertical shape.

  The holding member 1 of the first embodiment is a piece material having an extremely short width as shown in the drawing, and a plurality of holding members 1 are attached at predetermined intervals in the length direction of a steel plate 4 which is a C-type steel. In addition, the holding member 1 includes the support piece portion 22 because the holding member 1 does not include a support portion that supports the end portion (51y) of the other building material plate (5) adjacent to each other with the steel plate 4 interposed therebetween. By using the auxiliary member 2 together, all the building material plates 5 are supported.

  The mounting portion 11 in the first embodiment is formed in a U-shape that wraps the lower flange 41 of the steel plate 4 and the upward piece (lip) 411 formed at the tip thereof as shown in the figure, and a groove-like portion is provided above the upper portion. The holding part 12 provided with 13 is formed continuously.

  Moreover, the groove-shaped part 13 in this 1st Example is formed so that the space | interval of the upper piece 132 and the lower piece 131 is wider than the thickness of the edge part 51x of the building material board 5, and as shown to the right side of FIG. The end portion 51x is held loosely. In addition, a guide piece 14 that curves upward is continuously provided at the tip of the upper piece 132 of the groove 13, and plays a role of guiding the end 51 x of the building material plate 5 into the groove 13. That is, as shown on the left side of the figure, the end portion 51x of the building material plate 5 facing from the outside lower side (lower right side in the drawing) pushes up the guide piece 14, and the groove-like portion 13 is expanded against elasticity. At the same time, the holding portion 12 (grooved portion 13) is tilted toward the steel plate 4 side (left side in this case) against elasticity.

FIG. 2 shows an example of a construction procedure of a structure for holding the building material plate 5 between the steel molds 4 and 4 using the members 1 to 3, and constitutes a roof structure as shown in FIG. A steel plate 4, which is a C-type steel, is attached to the lower surface of the roof heat insulating material 6 at predetermined intervals. The holding member 1 is faced from the left side of the drawing, the decorative cover 3 is faced from the lower side of the drawing, and the auxiliary member 2 is faced from the right side of the drawing. What is necessary is just to attach to the type steel 4.
Also as a procedure, the holding member 1 may be attached to the mold steel 4 first, the decorative cover 3 may be attached thereafter, and the auxiliary member 2 may be attached last.

  As shown in the drawing, a temporary fixing double-sided tape 111 or the like is preferably provided on the inner surface side of the mounting portion 11 of the holding member 1, and the double-sided tape 111 is an upward piece 411 of the lower flange 41 of the steel plate 4. It is attached (adhered) to the outside. In this state, the groove 13 of the holding member 1 is located inside the opening of the steel plate 4. Therefore, even if there is no adhesion by the double-sided tape 111, the center of gravity of the holding member 1 is located in the opening of the steel plate 4, so that the holding member 1 is stably attached, but the holding member 1 is detached when the building material plate 5 is attached thereafter. Adhering with the double-sided tape 111 so as not to occur.

Subsequently, the decorative cover 3 is attached. As described above, one of the side surfaces (right side surface) 32 runs along the outside of the attachment portion 11 of the holding member 1, so that the lower flange 41 of the attachment portion 11 is attached together with its own attachment. It plays a role of assisting attachment (preventing detachment).
Further, since the other side surface (left side surface) 33 of the decorative cover 3 is attached along the web 42 of the steel plate 4, when the auxiliary member 2 is attached in the next step, the vertical piece 21 and the web are attached. 42 and attached in a sandwiched manner.

After that, the auxiliary member 2 is attached. As described above, the engaging piece 23 provided at the upper end of the vertical piece portion 21 is engaged with the upper flange 43 of the mold steel 4 and the plurality of raised portions 331 of the decorative cover 3 are cut and empty. Positioning is performed in a state of being engaged with each of the portions 211, and the fixing screw 2 b is driven from the side (left side) and attached to the web 42 of the die steel 4.
In this step, the auxiliary member 2 is fixed by the fixing screw 2b, and the vertical piece portion 21 extends along the web 42 of the steel plate 4 through the other side surface 33 of the decorative cover 3. The decorative cover 3 is also fixed to the steel plate 4 together with the attachment of 2.
In addition, since the decorative cover 3 has a configuration in which one side surface 32 is along the outside of the mounting portion 11 of the holding member 1 as described above, the holding member 1 is also integrated by fixing the decorative cover 3. It is attached to the mold steel 4.
After all, in this process, not only the auxiliary member 2 is simply fixed to the steel plate 4 by the fixing screws 2b, but the decorative cover 3 is also fixed integrally, and thereby the holding member 1 is also integrated. Fixed.

Then, as shown on the left side of FIG. 2, the end portion 51x of the building material plate 5 facing from the outside lower side (right side lower side in the drawing) presses the guide piece 14 of the holding member 1 so as to push up (= apply a pressing force). Then, the groove-shaped portion 13 is expanded against the elasticity, and the holding portion 12 (groove-shaped portion 13) is tilted toward the mold steel 4 side (in this case, the left side) against the elasticity.
In this state, the other end side (right end) of the building material board 5 is rotated so as to be lifted, and the other end (right end) of the building material board 5 is set to the substantially horizontal shape as shown by the dotted line in FIG. When the position is adjusted so as to abut against the steel plate 4 (auxiliary member 2) shown on the right side, one (left side) end 51x of the building material plate 5 also slides to the right side, and the pressing force is released. Therefore, the holding part 12 (groove part 13) of the holding member 1 is elastically restored to the original shape, and the end part 51x of the building material plate 5 is held in the groove part 13 to obtain the state of FIG.

In the holding structure of FIG. 2 constructed in this way, one (left side) end 51x of the building material board 5 is held by the groove-like part 13 of the holding member 1, and the other (right side) end of the building material board 5 is included. The part 51y will be in the state supported by the support piece part 21 of the auxiliary member 2 in abutting form. Therefore, the groove 13 is not always pressing (pressing) the end 51x of the building material plate 5, but plays a role of pressing this end 51x when some load is applied due to an earthquake or the like. Fulfill.
Moreover, since the lower end of the guide piece 14 of the holding member 1 faces in a close proximity above one (left side) end portion 51x of the building material board 5, the action of this guide piece 14 (= pressing piece) The role of pressing the end portion 51x is more reliably fulfilled.
Furthermore, since the pressing piece 212 of the auxiliary member 2 faces above the other (right side) end portion 51y of the building material board 5, when a load due to an earthquake or the like is applied due to the action of the pressing piece 212, The role of pressing the other end 51y is fulfilled.

  The holding structure of the second embodiment shown in FIG. 3 is a building material plate 5B in which end portions 51bx and 51by located on the left and right sides are formed in a stepped shape with the lower surface side cut out. The distance between the groove-like portions 13b (carrying portions 12b) of the holding member 1B that holds the holding portions 1B is reduced by the amount that the thicknesses of 51bx and 51by are reduced. All other members and the like are the same as those in the first embodiment, and the same reference numerals are given to the drawings and description thereof is omitted.
