Description

  The present invention prevents the floating or deformation of functional materials such as heat insulating materials, decorative materials, and ceiling boards disposed on the indoor side such as steel materials (roof purlin) used as a framework of the roof, and continuously The present invention relates to a functional material holding structure capable of maintaining an aesthetic appearance.

As various steel-framed building structures, multiple roof purlins made of C-shaped steel are fixed parallel to the direction of the eaves on H-shaped steels and the like that are placed with a gradient, and roof base materials are placed on top of these roof purlins. Structures that are laid and mounted are known.
On the other hand, particularly in a large-sized building, the roof base such as channel steel or C-shaped steel constituting the roof purlin is exposed on the indoor side, so that 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 channel steel and a decorative holder attached to the first holding member, and a structure using the same.
In this Patent Document 1, a space is formed between the building materials 11a and 11b held between the channel steels and the field board 6 disposed above the building materials 11a and 11b. In particular, members are disposed in the space. Absent.
Further, in Patent Document 2, a ceiling material is hooked on a lip of grooved steel with a lip, and ends of the ceiling material are arranged so as to overlap each other.
In particular, no member is arranged above the ceiling plate 10 held between the channel steels in Patent Document 2.

Japanese Patent No. 5561650 JP 2007-239360 A

  As described above, neither the structure of Patent Document 1 nor the structure of Patent Document 2 shows a flat appearance at the beginning of construction because no members are particularly arranged in the upper space of the building material and ceiling plate. However, after the lapse of time, the building materials and the ceiling board were lifted (warped) due to heat, humidity, or external force, and there was a risk of causing deformation or dropping.

  Therefore, the present invention prevents the lifting and deformation of functional materials such as heat insulating materials, decorative materials, and ceiling boards, etc., which are disposed indoors by using steel materials (roof purlins) used as the framework of the roof. The purpose is to propose a functional material holding structure that can maintain the ceiling aesthetic.

The present invention, which was proposed in view of the above, a functional material holding structure functional material is disposed between the plurality of shape steel that is fixed to the indoor side of the roof purlins or roof insulation, functions The end support material that holds the property material between adjacent mold steels is a central vertical piece along the web of the mold steel in a mounted state, a horizontal piece along the lower flange of the mold steel, and an inner vertical piece rising from the horizontal piece A support portion for supporting an end portion of a functional material provided on the back side of the steel plate and provided on the back side of the steel plate. End support material that can be mounted from the indoor side, has one end of the functional material supported by the lip of the lower flange of the mold steel, and the other end is mounted on the mold steel adjacent to the lower flange side of the mold steel The functional material is held between the adjacent steel molds by being supported by the support portion. The roof purlins or roof insulation material and the functional material holding structure characterized by comprising placing a prevention material floating between the functional material (hereinafter, simply referred to as holding structure) proposes a.

The present invention also proposes a holding structure in which, in the holding structure, the anti-lifting material has a position restricting portion.
In particular, the position restricting portion is preferably a claw portion that bites into the surface of the functional material.

  The present invention also proposes a holding structure characterized in that a decorative material for covering the mold steel is provided in the holding structure.

The holding structure of the present invention prevents the functional material disposed between adjacent steel molds from being lifted or deformed after aging, and is provided with a floating preventing material in the space between the housing and the functional material. Is.
Therefore, in this holding structure, when some stress due to heat, humidity, or external force is applied, the space between the housing and the functional material is narrowed, so that the functional material does not come off and prevents the functional material from coming off. Therefore, there is no occurrence of lifting (warping) such that the functional material comes off.
In addition, since the functional material is held between adjacent steel molds using a holding material having a specific configuration, a holding structure can be constructed substantially by this holding material and the lifting material, and member management is easy. The installation can also be done very easily.

Further, when the anti-lifting material has a position restricting portion, even if the anti-lifting material is smaller than the height (thickness) of the space separating the housing and the functional material, the anti-lifting material does not move due to an inclination at the time of installation. When some stress is applied, a pressing action from above can be achieved at a desired position of the functional material.
In particular, when the position restricting portion is a claw portion that bites into the surface of the functional material, it can be easily attached to the surface of the functional material in advance.

  In addition, when a decorative material for covering the mold steel is provided, the decorative material such as a ceiling finishing material and a decorative cover can make the mold steel invisible from below, so that the ceiling landscape is not impaired.

The present invention is a functional material holding structure in which a functional material is disposed between a plurality of mold steels fixed to a housing, and a floating prevention material is disposed between the housing and the functional material. It is characterized by.
For the structure (configuration) for disposing the functional material between adjacent steel plates, an end support material having the following configuration is used .
The end support member includes a central vertical piece along the web of the steel mold in a mounted state, a horizontal piece along the lower flange of the steel mold, an inner vertical piece rising from the horizontal piece, and an outer vertical piece. And a horizontal piece portion provided on the outer vertical piece portion and disposed on the back side of the shape steel, and attached to the respective shape steel from below. The end support material 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.
In addition, although this edge part support material is a member for mainly supporting the edge part of the functional material arrange | positioned between adjacent steel molds, in the illustrated Example mentioned later, to the steel mold of the decorative material which coat | covers steel molds. It also serves as a member for assisting the mounting.

The anti-lifting material may or may not be an elastic body, and is disposed in a space separating the housing and the functional material, and when the stress is applied in the thickness direction, the width (height) in the thickness direction functions. There is no particular limitation as long as the height is not changed to the height at which the material is removed.
That is, this anti-lifting material prevents the functional material from coming off due to the narrow space between the housing and the functional material when some stress due to heat, humidity, or external force is applied as described above. The anti-lifting material is disposed on the surface, and the anti-lifting material itself does not always need to be in contact with the casing and the functional material at all times.
Therefore, the dimension in the thickness direction of the anti-lifting material may be smaller than the height (thickness) of the space separating the casing and the functional material.

  As such a lifting prevention material, a piece material is desirable, for example, a pipe material (round, square) such as a vinyl chloride pipe, or a spherical body (hollow, solid) of a rubber-based outer skin or a resin-based outer skin, For example, a metal plate, a hard resin plate, or the like may be formed into a substantially inverted U shape. In addition, the anti-lifting material is not limited to a newly created material, and products, end materials, and the like produced for different uses may be used. In addition, backup materials molded from foam materials have been known for some time. However, it is practically difficult to lay such backup materials, and also in terms of cost (in terms of weight (functioning with backup materials)). Even if a considerable positive load acts on the material, this anti-lifting material has many advantages.

In the case where the anti-lifting material is a pipe material or a spherical body , when the height of the material itself is smaller than the height (thickness) of the space separating the housing and the functional material, a deviation movement such as rolling occurs. Although it is easy, there is an advantage that products and end materials produced for different applications can be easily obtained.
When the lifting prevention material is a plate-shaped molded body , it uses bending repulsion of a metal plate, hard resin plate, etc. as an elastic repulsion force, and is itself relatively light in weight, and also has various shapes. Can be easily formed.

Moreover, it is desirable that the anti-lifting material has a position restricting portion. In particular, when the dimension in the thickness direction of the anti-lifting material is smaller than the height (thickness) of the space separating the casing and the functional material, the anti-lifting material is likely to be displaced without any positional restriction.
The position restricting portion is configured to hold the anti-lifting material at a desired location of the functional material. For example, a wedge-shaped position restricting portion is provided, and the wedge-shaped position restricting portion is provided at the desired location of the functional material. It is only necessary to provide a receiving portion to which the portion is fitted, and these configurations are not particularly limited and may be formed in any manner.
Note that a double-sided tape or the like may be used for the same position regulation purpose.

As described above, the central vertical piece portion is formed along the web of the shape steel in the attached state, and is often formed into a vertical vertical piece as in the illustrated embodiment described later.
It is desirable that the central vertical piece is provided with a locking portion that can be attached to the pressing member attached before the end portion support member by engagement or the like. In addition, as this latching | locking part, although it was set as the ridge-shaped latching | locking part which protrudes outside with respect to the latching receiving part formed in the hole shape in the pressing material in the illustrated Example mentioned later, the structure is limited especially. It is not a thing.

  As described above, the horizontal piece extends from the lower end of the central vertical piece to the left and right, and is often formed into a horizontal horizontal piece as in the illustrated embodiment described later. The end piece support member can be firmly fixed to the lower flange of the steel plate by screwing to the side piece from below, and the side piece for fixing the ceiling finish material is fixed to the side piece. The ceiling support member can be firmly fixed to the lateral piece of the end support member by screwing it along the lower side.

  As described above, when the end support member holds the functional material between adjacent mold steels, it is desirable to use C-type steel or lip Z-type steel having a lip as the mold steel, and the tip of the lip of the mold steel Can support one end of the functional material, and the other end is supported by an end support (holding material).

  It is desirable that an inner vertical piece is formed in the portion extending to the lower flange side of the horizontal piece portion, and the end of the functional material disposed on the back side of the lower flange of the shape steel in the opposite extending portion. It is desirable to form an outer vertical piece portion in which a support portion for supporting the portion is provided at the upper end.

  As described above, the inner vertical piece refers to a vertical piece that rises from the portion of the horizontal piece that extends to the lower flange side. Although the latching | locking part where an upper end is lower than the lip of the lower flange of a type steel is contained, these are not essential and only either one may be formed.

As described above, the support portion is provided on the outer vertical piece portion that rises from the extending portion in the direction opposite to the lower flange side of the horizontal piece portion, and is an end portion of the functional material disposed on the back side of the shape steel. It is desirable that the lip upper end of the lower flange of the mold steel supporting one end is substantially the same as the support height.
In the illustrated embodiment described later, this support portion is provided at the upper end of the outwardly inclined vertical piece, but the configuration is not particularly limited. In addition, a fitting groove that opens outward is formed as an attachment site for fitting the ceiling finish material and the decorative cover in a fitting shape below the support portion, but the configuration is particularly limited. It is not a thing.

  The restriction piece, which is one of the inner vertical piece portions, is along the lip (outside) of the lower flange of the shape steel in the mounted state, and includes the central vertical piece portion, the horizontal piece portion, and the restriction piece. A substantially U-shape that opens upward is formed. Therefore, this end portion support material can be temporarily fixed to the lower flange of the steel plate in a fitted state from below, and the screwing operation from below the horizontal piece portion can be performed stably.

As for the latching | locking part which is one of the said inner side vertical piece parts, it is desirable for an upper end to be formed lower than the lip of the lower flange of a shape steel.
In the illustrated embodiment to be described later, this locking portion is formed in a shape in which the upper end of the outwardly inclined vertical piece is bent inward and upward, and is formed symmetrically with the inclined vertical piece in which the support portion is formed. However, the configuration is not particularly limited. In other words, this locking part is used as a mounting part for a ceiling finishing material or a decorative cover, and since the upper end is formed lower than the lip of the lower flange of the mold steel, it interferes with the functional material supported on the upper end of the lip. The ceiling finish and the decorative cover can be locked without receiving.

Next, the steel plate used in the present invention to which the end support material is attached will be described.
The mold steel may have at least a web and a lower flange, and specifically, an H-shaped steel having a lower flange on both the left and right sides, an I-shaped steel, a groove-shaped steel having a lower flange only on either the left and right, and a Z-shaped steel , L-shaped steel, C-shaped steel having an upward piece at the tip of the lower flange (= lip groove shaped steel), lip Z-shaped steel, and the like.
Among the above steel shapes, C-type steel having a lip and lip Z-type steel are desirable. In addition, although these mold | steel steels are arrange | positioned so that a lower flange may extend in the same direction and form a purlin, you may make it connect and use these mold steels back to back in part.

Subsequently, the functional material held between the molds by the end support material will be described.
As the functional material, a heat insulating material such as a mat or board made of glass wool, foamed resin, etc., a sound absorbing material, a fireproof material, or various materials can be used. It may be a body, may be hard or soft, and its thickness may be set as appropriate.
Further, the end portion of the functional material is not limited to one cut from the surface in a substantially vertical shape, and for example, the end portion may be formed in a step shape with the lower surface side cut out.

A presser material may be used for the purpose of more stable holding of the functional material, and the presser material includes a vertical piece portion along the web of the mold steel and a presser piece extending downward from the vertical piece portion. It is a configuration.
As this pressing member, it is desirable to provide a hooking portion for hooking on the upper flange of the steel plate at the upper end of the vertical piece. This latching part can be used as a temporary stopper when a screw is driven into the vertical piece part from the side to fix the pressing member to the steel plate.

  The vertical piece portion is a substantially vertical vertical piece along a web of a steel mold, and is provided with a locking receiving portion to which a locking portion provided on a central vertical piece portion of the end support member can be attached. Is desirable. In addition, although it was set as the structure which can form the hole shape and can lock the ridge-shaped latching | locking part provided in the center vertical piece part of the said edge part support material as this latching receiving part, the structure is limited especially is not.

  The pressing piece extends downward from the vertical piece and faces the surface of the functional material, and holds and holds the surface of the functional material. The shape of the pressing piece is not particularly limited, and may be in contact with the surface of the functional material or not. In other words, it is not limited to the mode in which the end surface of the functional material is always pressed from above, and includes a mode of pressing the end when any load is applied, but when considering the mounting stability, Needless to say, it is desirable to continuously and elastically hold the end of the functional material from above.

Moreover, the decorative material which coat | covers the said shape steel from the downward direction is demonstrated.
This decorative material includes a “decorative cover” that covers the mold steel and a “ceiling finish” that covers the mold steel and the functional material, both of which have a decorative surface portion and are continuous in the length direction of the mold steel. It is formed in a scale. When using a decorative cover, the building material board such as a ceiling board or a decorative board is often used as a functional material. When using a ceiling finishing material, the functional material itself is hidden, so the building material board is included. Various heat insulating materials can be used. Moreover, as this decorative material, what is attached for every type steel may be used, and what is attached so that it may straddle between adjacent type steels may be used.
In addition, you may comprise in these decorative materials the structure which assists (strengthening) attachment of a shape steel and the edge support material mentioned later.

The horizontal piece 12 is a horizontal piece that extends along the lower flange 41 of the steel plate 4 in the attached state as described above, and extends horizontally from the lower end of the central vertical piece 11 in the left-right direction. . The horizontal piece 12 can be firmly fixed to the lower flange 41 of the steel plate 4 by screwing (screw 1b) from below.
The inner vertical piece 13 is formed on the extending portion of the horizontal piece 12 toward the lower flange 41, and the support portion 141 is provided on the back side, that is, the extending portion of the lower flange 41 in the opposite direction. The outer vertical piece 14 is formed.

As described above, the inner vertical piece 13 refers to two vertical pieces rising from the extending portion of the horizontal piece to the lower flange side. More specifically, the inner vertical piece 13 is attached to the lip of the lower flange of the shape steel in the mounted state. The restriction piece 13 </ b> A and the locking portion 13 </ b> B whose upper end is lower than the lip of the lower flange 41 of the steel plate 4 are indicated.
13 A of said control pieces are the structures for forming the substantially U shape which upper direction open | releases by the said center vertical piece part 11, the said horizontal piece part 12, and this control piece 13A, and this substantially U shape is a shape steel 4 The lower flange 41 can be temporarily fixed in a fitted state from below, and the screwing operation from below the horizontal piece portion 12 can be performed stably.
Moreover, the said latching | locking part 13B is formed in the shape which bent the upper end of the inclination-shaped vertical piece to the outer side (right side in a figure) inside upper direction.

Further, the support portion 141 is provided at the upper end of the outer vertical piece portion 14 rising from the horizontal piece portion 12 as described above, and the end portion 51y of the functional material 5 disposed on the back side of the lower flange of the steel plate 4. The upper end of the lip 411 of the lower flange 41 of the mold steel 4 that supports the one end 51x is substantially the same as the support height.
The support portion 141 is provided at the upper end of the outer vertical piece portion 14 that is an inclined vertical piece outward (left side in the drawing) in the illustrated embodiment, and below the support portion 141 is the ceiling support material 7. As an attachment portion to which the engagement lateral piece 721 is attached in an engagement state, a fitting groove 142 that opens outward (left side in the drawing) is provided.

  In addition, since the outer vertical piece part 14 on which the locking part 13B and the support part 141 are formed is formed in a bilaterally symmetric shape, the ceiling finishing material 7 formed in a substantially bilaterally symmetric form as described above. Can be easily attached in a fitting form from below the end support 1.

  The steel plate 4 is a lip groove steel (C steel) having flanges 43 and 41 at both ends (upper and lower ends) of the web 42 arranged in the vertical direction, and the lower flange 41 having an upward piece 411 at the tip is shown in the drawing. It extends to the right.

  Further, the functional material 5 is a member having various functions required for a building such as heat insulation, sound absorption, sound insulation, fire resistance, and the like disposed so as to be bridged between adjacent steel shapes 4 and 4. The end portions 51x and 51y located at both ends in the first embodiment are cut from the surface in a substantially vertical shape. For the sake of convenience, the left end is 51x and the right end is 51y on the drawing.

Furthermore, the holding structure uses a pressing member 2 for the purpose of more stable holding of the functional material 5, and the pressing member 2 is a web of the steel plate 4 as shown in FIG. 42, and a pressing piece 22 extending downward from the vertical piece 21.
At the upper end of the vertical piece portion 21, there is provided a hooking piece 23 that is bent in a substantially horizontal shape and hooked to the upper flange 43 of the steel plate 4, and a screw 2b is driven into the vertical piece portion 21 from the side and this presser is pressed. It can be used as a temporary fixing when the material 2 is fixed to the mold steel 4. The pressing piece 22 is formed at a plurality of locations so as to protrude outward by cutting and raising by a plurality of rectangular cuts, and the lower end of the pressing piece 22 is close to the surface of the functional material 5 in the mounted state. ing. In addition, a locking receiving portion 211 formed in a hole shape is provided below the vertical piece portion 21.

Moreover, the decorative material 3 which covers the lower flange 41 of the steel plate 4 is used for the holding structure. As shown in FIG. 4B, the decorative material 3 is a long material having a substantially bowl-shaped cross section in which the left and right sides of the decorative surface 31 that is the bottom face rises. is there.
Then, on one side surface (right side surface) 32, an engagement piece 321 that engages with the upper end of the locking portion 13B of the end portion support member 1 is provided inward, and on the other side surface (left side surface) 33, Is an engagement piece 331 that engages from the side with a fitting groove 142 provided below the support portion 141 along the outer side of the vertical piece 14 rising from the edge of the lateral piece portion 12 of the end support member 1. Is provided inwardly and can be fitted to the end support 1 from below.
Since this decorative material 3 is not involved in supporting the functional material 5, it can be attached at any time after the construction of the end support material 1 is finished, and it does not hinder the construction.

The construction procedure for holding the functional material 5 between the mold steels 4 and 4 using the end support material 1 and the presser material 2 is shown in a simplified manner in FIG. The pressing member 2 is fixed to the above.
As shown on the right side of the drawing, the pressing member 2 is attached in a temporarily fixed state in which the vertical piece portion 21 is placed along the web 42 of the steel plate 4 and the hook portion 23 is hooked on the upper flange 43 of the steel plate 4. In this state, the screw 2b is driven and fixed from the side (left side of the drawing).

Next, one end 51x of the functional material 5 is supported by the lip 411 of the steel plate 4 located on the left side of the drawing.
In the figure, the end support 1 and the decorative material 3 are already attached to the steel plate 4 on the left side of the drawing, but the same is true even if not attached, and the back surface of one end 51x of the functional material 5 is the same. Is supported on the web 42 of the mold steel 4. Further, since the lifting preventing material 9 is provided with a position restricting portion (claw portion) 931, even if it is fixed in advance to a predetermined position of the functional material 5, it may be displaced due to an inclination during construction. Absent.

Subsequently, with respect to the steel plate 4 on the right side of the drawing, the other end 51y of the functional material 5 is supported by the support portion 141 of the end support 1 while rotating so that the functional material 5 becomes substantially horizontal. (Tilt) and end support 1 is attached.
As described above, the end support 1 is formed in a substantially U-shape with the central vertical piece 11, the horizontal piece 12, and the restricting piece 13 </ b> A open upward. As shown by the drawing arrow, it can be temporarily fixed to the lower flange 41 of the steel plate 4 from below. Further, the central vertical piece portion 11 of the end support member 1 has a ridge-like engaging portion 111 that is engaged with a hole-like engaging receiving portion 211 formed in the vertical piece portion 21 of the presser member 2. The stop state becomes more stable. Then, the subsequent screwing operation (screw 1b) from the lower side of the horizontal piece portion 12 can be stably performed, and the functional material 5 is also kept substantially horizontal.

In addition, although the functional material 5 is hold | maintained in the state hold | maintained substantially horizontal shape, both end surfaces are hold | maintained by the webs 42 and 42 of the steel plates 4 and 4 which adjoin each other.
In particular, the end 51x on one side of the functional material 5 is such that the tip of the screw 2b used for fixing the presser material 2 extends through the web 42 of the die steel 4 to the surface side of the functional material 5. Therefore, it plays the role of holding and holding in the same manner as the holding piece 22 at the end 51y on the other end side.

Thereafter, the decorative material 3 is attached to the adjacent end support members 1 and 1 attached in a fitting manner from below.
Since this decorative material 3 is provided with the engaging pieces 321 and 331 inwardly on the side surfaces 32 and 33 as described above, the engaging portion 13B of the end support member 1 and the fitting groove 142 are viewed from below. It can be attached in a fitting form.

Therefore, in this holding structure, when some stress due to heat, humidity, or external force is applied, the space between the housing 6 and the functional material 5 is narrowed so that the functional material 5 is not detached. An anti-lifting material 9 is arranged.
Specifically, when stress is applied from below, the top of the curved surface portion 91 abuts against the housing 6 and receives a force that deforms the curved surface portion 91 in the direction of expanding left and right. At that time, since the fixing portion 93 is fixed by the locking of the position restricting portion (claw portion) 931 and the adhesion of the double-sided tape 9b, the contact portion 92 is deformed so as to slide (slide) outward. . When subjected to such deformation, the pressure from above acts on the functional material 5 due to its elastic repulsion, so that the stress from below is released and the anti-lifting material 9 is elastically recovered to its original shape. Return. Therefore, the functional material 5 is not lifted (warped), and there is no possibility of causing deformation or dropping.

  In addition, in this first embodiment, in addition to the press-holding effect of the lifting-preventing material 9, the one end 51x and the other end 51y of the functional material 5 are pressed and held by the screw 21b and the pressing piece 22, respectively. Therefore, when a stress that pushes up the functional material 5 from the indoor side (lower side) is applied, the action against the stress is exerted at the center and both ends of the functional material 5, The effect of preventing the functional material 5 from coming off or falling off is reliably achieved.

  Moreover, in the said Example, the said edge part support material 1 supports the other edge part 51y of the functional material 5 which made one edge part 51x be supported by the lip 411 of the lower flange 41 of the shape steel 4, The functional material 5 can be held between the adjacent mold steels 4 and 4, and a structure in which the functional material is arranged between the adjacent mold steels by substantially only one member of the end support material 1 can be constructed.

  Further, the functional material 5 held by the end support material 1 can be disposed so that the end surface thereof is abutted against the webs 42 and 42 of the adjacent steel plates 4 and 4. Therefore, the weak point part of heat insulation performance is not produced.

  The holding structure of the second embodiment shown in FIG. 2 (a) uses a pipe material (hollow) lifting prevention material 9B shown in FIG. 2 (c) in place of the substantially inverted U-shaped lifting prevention material 9. It is an example. Since other members and configurations are the same as those in the first embodiment, the same reference numerals are given to the drawings, and descriptions thereof are omitted.

  Since the lifting prevention material 9B of the second embodiment is a pipe material (hollow) as described above, it moves around the surface of the functional material 5 during the inclination or the like during construction as shown in FIG. Although it is preferable to provide a position restricting portion to prevent, since the position restricting portion 931 having the above configuration cannot be formed, it is preferable to provide a position restricting (material) equivalent to a double-sided tape.

  The holding structure of the third embodiment shown in FIG. 3A is the same as that of the first embodiment in that the substantially inverted U-shaped anti-lifting material 9 is used. However, the holding structure 3 is a decorative cover.
