Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite panel used as a structural panel for constructing a structural frame such as a floor of a building by a frame wall method or as a floor panel of a building made of a steel frame.

[0002]

2. Description of the Related Art A so-called framing wall method is mainly composed of framing materials such as an outer frame 20, a middle frame 21 and a horizontal frame 22 having a standardized rectangular cross section as shown in FIGS. 23 is a surface material such as structural plywood or gypsum board 24
Is used to form a structural panel 25, and by using the structural panel 25, a structural frame of a building such as a rigid floor or wall is constructed without using columns.

[0003] The structural panel 25 is manufactured at a factory or the like and then carried into the site.
It is most important that No. 5 is manufactured to the standard, which has a great effect on construction accuracy.

For example, as shown in FIGS. 10 and 11,
When the floor is to be constructed with several structural panels 25, if the structural panel 25 is larger than the standard dimensions due to the warp or curling of the frame material such as the outer frame 20 or the face material 24, The total area S ₁ of the structural panel 25 becomes larger than the design floor area S ₂ (see FIG. 10), and conversely, the total area S ₁ of the structural panel 25 becomes the design floor area S _2.
It becomes smaller (see FIG. 11), and the floor as designed cannot be constructed.

For this reason, when manufacturing the structural panel 25, the dimensional error due to the warpage of the frame assembly material and the displacement generated when the face material 24 is nailed are corrected.
In order to ensure the shape and dimensions of
As shown in FIGS. 3A and 3B, it is necessary to fix at least three places at both ends and the center of each frame assembly material with the fixing jig 26.

[0006] For the same reason, the face material 24 is, for example, also shown in FIG.
As shown in FIGS. 3A and 3B, it is necessary to use a fixing jig 26 to fix the surroundings at several places. In this case, in particular, the middle frame 21 installed inside the face material 24 is
If 5 satisfies the required structural performance, there is no particular effect on the shape and dimensions of the entire panel,
If the middle frame 21 is not installed at a predetermined position due to a warp or other dimensional warp, the middle frame 21
May not be able to be accurately grasped on the middle frame 21 because the position of the middle frame 21 cannot be grasped. For this reason, the middle frame 21 also needs to be fixed at both ends and the middle portion with the fixing jig 26,
A considerable number of fixtures 26 are required.

Further, at present, several types of structural panels 25 having different dimensions and the like are often manufactured in one manufacturing line. In this case, as shown in FIGS. It is necessary to be able to change the position of the tool 26 each time.

Further, the structural panel thus formed has been fixed to the structural frame using fixing members such as straps and bolts. Generally, as a method of fixing an end of a floor panel to a steel beam, for example, as shown in FIG.
As shown in (b), a method is known in which a joint fitting 28 separately formed is protruded from an end of the floor panel 27 and the joint fitting 28 is bolted to a steel beam 29 with a fixing bolt. However, in such a method, a joint fitting 28 is attached to an end of the floor panel 27.
Has to be attached by welding or the like, and there has been a problem that the manufacturing cost is increased.

The present invention has been made in order to solve the above problems, and has extremely high product precision, particularly in terms of shape and dimensions, and can be easily attached to a structural body such as a steel beam. It is an object of the present invention to provide a composite panel in which the number of fixing jigs used for accurately maintaining the shape and dimensions can be significantly reduced.

[0010]

According to a first aspect of the present invention, there is provided a composite panel according to the present invention, comprising: a deck steel sheet having an axially continuous flange and a web; A plywood having the same size as that of the plywood is fixedly attached to the flange.

According to a second aspect of the present invention, in the composite panel of the first aspect, the deck steel plate is formed in a corrugated shape continuous from the plurality of flanges and the web in a direction perpendicular to the axis. According to a third aspect, in the composite panel of the first aspect, the deck steel sheet is formed by projecting a plurality of webs at predetermined intervals on one side of a flange formed to be the same size as the plywood.

According to a fourth aspect of the present invention, in the composite panel of the first, second or third aspect, a flat joint is formed by pressing at an end of the deck steel plate.

[0013]

1 (a) and 1 (b) show an example of a composite panel. In the drawing, one side of a deck steel plate 1 formed to a predetermined standard size has the same plane size as the deck steel plate 1. FIG. By attaching the plywood 2 thus formed, the rectangular steel composite panel 3 is formed from the deck steel plate 1 and the plywood 2.

The deck steel plate 1 is formed in a corrugated shape continuous in a direction perpendicular to the axis (width direction) so as to have high bending rigidity from a plurality of flanges 1a and webs 1b continuous in the axial direction.

The deck steel plate 1 may be formed by welding a flange member and a web member by welding or the like. However, the steel plate is formed by rolling a steel plate so that the one-layer flange and the two-layer web are integrated. You may.

The plywood 2 is a structural plywood or the like having the same plane size as the deck steel plate 1 and is attached to the side of the deck steel plate 1 having the flange 1a, and is nailed or screwed to the flange 1a. It is fixed.

In such a configuration, the deck steel plate 1 is formed in a corrugated shape continuous from the plurality of flanges 1a and the web 1b that are continuous in the axial direction in the direction perpendicular to the axis, so that the deck steel plate 1 has extremely large bending rigidity and warp. It is unlikely to cause warping or twisting.

For this reason, when the composite panel 3 is formed by nailing or screwing the plywood 2 to the deck steel sheet 1, the deck steel sheet 1 and the plywood 2 are, for example, as shown in FIG. In most cases, the fixed size and shape can be reliably maintained only by fixing the both ends and the intermediate portion with the plurality of fixing jigs 4. There is no need to fix with. Therefore, the fixing jig 4 can be largely omitted.

At this time, the deck steel plate 1 and the plywood 2 may be fixed together by a common fixing jig 4 as shown in FIG. 2B, or as shown in FIG. 2C. May be fixed separately.

Further, by forming the flanges 1a at a predetermined pitch (interval), the position of the flanges 1a can be easily grasped even from above the plywood 2, so that the nailing or screwing of the plywood 2 is performed from above the plywood 2. But you can do it accurately.

FIGS. 3 (a) and 3 (b) show another example of a composite panel, in which one side of a deck steel plate 1 formed to a predetermined standard size is formed in the same plane size as the deck steel plate 1 in the drawing. By attaching the plywood 2, a rectangular panel-shaped composite panel 3 composed of the deck steel plate 1 and the plywood 2 is formed.

The deck steel plate 1 is composed of a single flange 1a having the same plane dimensions as the plywood 2 and a plurality of webs 1 continuous in the axial direction.
In addition, a web 1b having a substantially L-shaped cross section is formed on one side of the deck steel plate 1a at a predetermined interval in a direction perpendicular to the axis (width direction) so as to have high bending rigidity. .

Here, the deck steel plate 1 may be formed by welding a flange member and a web member by welding or the like, but by forming a steel plate into a roll, the one-layer flange and the two-layer web are formed integrally. You may.

The plywood 2 is a structural plywood or the like having the same plane size as the deck steel plate 1.
a and is fixed to the flange 1a by nailing or screwing.

In such a configuration, since the deck steel plate 1 is formed by projecting a plurality of webs 1b continuous in the axial direction at predetermined intervals in the direction perpendicular to the axis, the deck steel plate 1 has extremely high bending rigidity, and warp and twist. It is hard to cause warping.

For this reason, when the composite panel 3 is formed by nailing or screwing the plywood 2 to the deck steel plate 1, the deck steel plate 1 and the plywood 2 are connected to each side as shown in FIG. At most both ends and middle part are fixed fixtures 4
The fixed size and shape can be reliably maintained only by fixing with the fixing member, and therefore, it is not necessary to fix the central portion with the fixing jig 4 as in the past. Therefore, there is an effect that a considerable number of fixing jigs 4 can be reduced.

At this time, the deck steel plate 1 and the plywood 2 may be fixed together by a common fixing jig 4 as shown in FIG. 4B, for example, or as shown in FIG. The deck steel plate 1 and the plywood 2 may be fixed along the entire length of each side.

Further, if the fixing jig 4 can be moved as shown in FIG. 5C, composite panels having different dimensions can be easily manufactured on one manufacturing line. FIG.
(A), (b) shows a deck steel plate 1 at the end of the composite panel 3.
This shows an example in which a flat joint portion 5 is protruded by pressing (end-close processing) the end of the flat joint.

In particular, FIG. 6 (a) shows an example in which the joint portion 5 projects on the same plane as the flange 1a, and FIG. 6 (b) shows the joint portion 5 projecting on the axis plane of the deck steel plate 1. In each example, bolt holes 6 are formed in the joint portion 5 at predetermined intervals in the direction perpendicular to the axis.

FIGS. 7 (a) and 7 (b) show an example in which the composite panel 3 is laid as a floor panel on the steel beam 7, and at this time, the joint portion 5 is connected to the steel beam 7 at the end. 7
And is fixed to the steel beam 7 by fixing bolts 8 passing through the bolt holes 6.

In particular, in the example shown in FIG. 7A, the concave portion 2 in which the bolt head 8a of the fixing bolt 8 is stored at the end of the plywood 2.
By forming a, the bolt head 8a is prevented from protruding to the floor surface.

The joint part 5 is composed of the deck steel plate 1 and the plywood 2
It may be protruded in any manufacturing process before or after mounting.

[0033]

The present invention has the above-described structure,
In particular, since the deck steel plate is integrally formed with a flange and a web that are continuous in the axial direction, the bending rigidity of the deck steel plate is extremely large, and warpage such as warpage or twisting hardly occurs.

For this reason, when a composite panel is formed by nailing or screwing a plywood to a deck steel plate, the deck steel plate and the plywood are connected to each other at most at both ends and an intermediate portion by several fixing jigs. The fixed size and shape can be reliably maintained only by fixing with.

Therefore, it is not necessary to fix the fixing jig to the center as in the past, and the number of fixing jigs to be used can be considerably reduced, and a composite panel with extremely high product accuracy can be provided.

Further, since the deck steel plate is formed in a corrugated shape continuous from the plurality of flanges and the web at a predetermined pitch in the direction perpendicular to the axis, the position of the flange can be easily grasped even from the plywood. The plywood can be precisely nailed or screwed to the flange.

Further, in the composite panel according to the third aspect,
Since the flange of the deck steel plate is formed in the same size as the plywood, the plywood can be accurately nailed or screwed to the flange at any position.

Furthermore, since flat joints are protruded from the end of the deck steel plate by press working, there is no need to dare to protrude the joint fittings formed in a separate process, and the production cost can be reduced. It is.
