Abstract

PURPOSE:To secure a story height without increasing an eaves height of a building, reduce a quantity of used steel material and reduce building costs, in fitting of a roof panel or floor panel to a building frame. CONSTITUTION:A support metal fitting 11, formed into a rectangular shape of fixed pieces 11a arranged and fixed in the direction orthogonal to the longitudinal direction of girders 3, 4, and placing pieces 11b arranged in the direction parallel to the longitudinal direction of the girders 3, 4 and fixed to both ends of the fixed pieces 11a, is arranged and fixed to each connection part between the girders 3, 4 and a column 1. An end of a panel 5c is placed on a support piece 11c of the placing piece 11b and a panel 5d thinner than the panel 5c is placed out the fixed piece 11a. Since a protrusion at a connection part between a girder rigidly joined to a column and another girder can be thereby avoided, installation of a bulk increasing material is not necessary over the whole length of the girder. Consequently, an eaves height can be decreased, and a quantity of used steel material in accordance with the bulk increasing material and length of the column due to bulk increasing can be reduced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a panel on a building frame when a roof or floor surface is formed by using a molded panel such as an ALC panel.

[0002]

2. Description of the Related Art In a building having a steel frame structure, a roof panel or a floor panel made of an ALC panel or the like is attached to a frame to form a roof or a floor surface. The panel has length, width,
Dimensions such as thickness have preset values, and both ends in the longitudinal direction are supported and attached to a beam that constitutes a skeleton.

A conventional roof / floor panel mounting structure will be described with reference to FIGS. Since the structure for attaching the roof panel to the frame and the structure for attaching the floor panel to the frame are substantially the same, the structure for attaching the floor panel to the beam will be described as a representative.

In the figure, a plurality of pillars are provided at predetermined positions in the building.
51 are arranged, and 2 depending on the installation position on this pillar 51.
Up to four girders 52 (52a, 52b) are connected. Pillar 51
The pillar-mounted large beam 51a and the large beam 52 rigidly contacted with each other are connected by connecting a connecting plate 53 to the flange portion and the web portion and fastening them with bolts and nuts.

Therefore, the connection plate 53 and the bolts and nuts are projected on the upper surface of the flange at the connecting portion between the large beam 51a with a pillar and the large beam 52 rigidly contacted with the pillar 51, and the large beam 52
Cannot be configured to be flush with the upper surface of. Therefore, a raising member 54 made of shaped steel such as lip grooved steel is fixed to the upper surface of the girder 52, and the raising plate 54 connects the connecting plate.
The lower surface level of the panel 55 is set by avoiding the protrusions of 53 and bolts and nuts and arranging the upper surface of the raising member 54 in the same plane.

The small beam 56 is arranged so that the upper surface thereof is flush with the raising member 54, and the panel 55 is provided to the one large beam 52a.
Are arranged in parallel at a pitch corresponding to the length of the
It is fixed to the other large beam 52b orthogonal to 52a.

A notch corresponding to the shape of the column 51 is formed in the panel 55 arranged around the column. For this reason, in order to support the notched portion of the panel 55 around the pillar, a reinforcing beam 57 having the same size as the raising member 54 is fixed by bridging the large beam 51a with a pillar rigidly connected to the pillar 51. ing.

When the panel 55 is laid, it has a function of securing a hanging allowance of the panel 55 and preventing a displacement at the time of an earthquake at a pitch corresponding to the width dimension of the panel 55 in advance on the upper surface of the raising member 54 and the beam 56. The slab plate 58 is welded. Then, one end of the panel 55 is placed on the raising member 54 fixed to the large beam 52a, and the other end is placed on the small beam 56 and laid over the entire floor surface, and at the same time, the slab plate 58 is jointed to the joint reinforcement. 59 is inserted.

[0009]

In the above-mentioned conventional panel mounting structure, the projections composed of the connection plate and the bolts, nuts, etc., which are formed at the connection portion between the girder with the pillar rigidly connected to the pillar and the girder are avoided. In order to do so, a raising member is arranged on the girder. Therefore, in order to secure the floor height, it is necessary to increase the eave height according to the height of the raised material.

This causes a problem that the effective floor height must be lowered in an area with a height restriction, and the length of the main pillars and studs becomes long. In addition to the increase in the amount of steel used for the pillar material, the area of the outer wall, partition wall, finishing material, etc. becomes large, which causes a problem of increasing equipment piping.

An object of the present invention is to provide a roof / floor panel mounting structure which can secure a floor height without increasing the eaves height of a building and can reduce the amount of steel used.

[0012]

In order to solve the above problems, a roof / floor panel mounting structure according to the present invention is a roof / floor panel in which a roof panel or floor panel is arranged on a frame to form a roof or floor. And a fixing piece arranged in a direction orthogonal to the longitudinal direction of the beam and fixed to the beam, and a roof / floor arranged parallel to the longitudinal direction of the beam and fixed to the fixing piece. A panel having a supporting metal piece composed of a mounting piece for mounting a panel, and an end portion of the roof / floor panel being mounted on the mounting piece of the supporting metal material, and a fixing piece being thinner than the thickness of the roof / floor panel. It is characterized by mounting.

[0013]

According to the above roof / floor panel mounting structure, it is possible to secure the floor height and mount the roof panel or floor panel to the frame without increasing the eaves height.

That is, a supporting metal piece composed of a fixing piece and a mounting piece fixed to the fixing piece is constructed in advance, and the supporting metal piece is attached to the connecting portion between the pillar and the girder so that the connecting portion is connected. It is possible to avoid protrusions consisting of the connection plate and bolts and nuts. Then, while placing the end of the roof / floor panel on the mounting piece of the supporting metal, the roof / floor panel is mounted on the fixed piece.
By placing a panel thinner than the floor panel, the roof / floor panel and a panel thinner than these can be attached to the body.

Therefore, both ends of the roof / floor panel can be placed and attached to the skeleton by the girder, girder and supporting metal without providing a raising member over substantially the entire length of the girder, and thus the eaves height should be increased. It is possible to secure the floor height.

[0016]

EXAMPLE An example of the roof / floor panel mounting structure will be described below with reference to the drawings. Roof according to the present invention
The floor panel mounting structure is such that the roof / floor panel ends are placed at positions corresponding to the connection between the girder with columns rigidly attached to the columns and the girders, and panels thinner than these panels are placed. By arranging the supporting hardware to support all the girders without attaching the raising material over the entire length of the girder,
It is configured so that it can be supported by a beam.

The structure for attaching the roof panel to the body and the structure for attaching the floor panel to the body are substantially the same. Therefore, in this embodiment, the mounting structure of the floor panel will be described. FIG. 1 is a schematic perspective view of the panel mounting structure according to the present embodiment as seen from the floor side, FIG. 2 is a schematic view of FIG. 1 taken along the line II-II, and FIG. FIG. 4 is a diagram for explaining the structure of another supporting metal.

In the figure, at the positions corresponding to the respective levels of the pillar 1, a large number of pillar-bearing beams 2 corresponding to the arrangement position in the building are arranged. That is, two pillar-mounted girders are arranged in orthogonal directions in the pillars corresponding to the corners of the building, and three pillar-mounted girders are arranged in the pillars other than the corners in the wall of the building. . In this embodiment, a pillar 1 located in the center of a building is shown, and four pillar-mounted girders 2 are arranged on this pillar 1, and girders 3 and 4 are connected to each pillar-mounted girder 2.

Beams 6 are arranged in parallel with the girders 3 and at intervals equal to the length of a panel 5a, which will be described later. The ends of the girders 6 are arranged in the direction orthogonal to the girders 3. Is stuck to. The upper surfaces (upper end surfaces of the flanges 3a, 4a, 6a) of the large beams 3 and 4 and the small beams 6 are arranged in the same plane.

As described above, the panels 5a and 5b are arranged on the beams 3, 4 and 6 arranged at the same level. That is,
A panel 5a having a size as a preset floor panel is arranged so as to straddle the large beam 3 and the small beam 6 at both ends.
Panel 5b having a width equal to that of the girder 4 is attached to the girder 4.
Will be placed along.

Therefore, when a panel 5b having a width equal to the width of the pillar 1 is arranged on the girder 4, the panel 5b is arranged between the pillar 1 and another adjacent pillar and in a direction parallel to the girder 4. Thus, a floor surface having a width substantially equal to that of the pillar 1 is formed, and the other floor surface is formed as a rectangular surface having a large beam 3 and a small beam 6. Therefore, the panel 5a placed on the girder 3 and the girder 6
It is possible to make all of the shapes rectangular.

As described above, since all of the panels 5a and 5b can be formed in a rectangular shape, even when the panel 5a is arranged around the pillar 1, the panel 5a is attached to the girder 3. Since it can be supported by the beam 6, it is not necessary to provide a special reinforcing material around the pillar.
Therefore, it is possible to reduce the amount of steel material used when constructing the building frame.

The girder 2 with pillars and the girders 3 and 4 provided on the pillar 1 are
As shown in FIGS. 2 and 3, the connection plates 7 and 8 are arranged on the flanges 2a and 3a of the respective members 2 and 3, and the connection plate 9 is arranged on the webs 2b and 3b.
The connection plates 7 to 9 are connected by fastening them with bolts and nuts 10.

Therefore, the connecting plate 7 and the bolt or nut 10 project at the connecting portion between the large beam 2 with pillars and the large beams 3, 4. For this reason, a supporting metal member 11 is arranged at the connecting portion so as to avoid the protrusion and to support the end portion of the panel 5c arranged at the connecting portion and to mount and support the panel 5d.

The supporting metal 11 is arranged in a direction orthogonal to the direction in which the girders 3, 4 are arranged, and the flanges 3a,
4a, a fixing piece 11a fixed by welding or the like, and a mounting piece arranged in parallel to the arrangement direction of the girders 3, 4 and fixed to both ends of the fixing piece 11a and for mounting the ends of the panel 5c. 11b
And has a rectangular overall shape. The support hardware 11 is manufactured in a factory in advance and supplied to the building construction site.

The fixing piece 11a is made of a mountain-shaped steel or a member made by bending an L-shaped plate material having a strength capable of supporting the weight of the panel 5d to be placed and the weight of the supporting piece 11c. The flange portion of the member is arranged above so that the member can be mounted in a stable posture. The fixed piece 11a preferably has a length substantially equal to the width dimension of the column 1.

The mounting piece 11b is a panel 5 on which an end is mounted.
It is made of a chevron steel or a plate material having a strength capable of supporting c and is bent into an L shape, and the flange of at least one of the two mounting pieces 11b welded to both ends of the fixing piece 11a is projected. The support piece 11c is formed by the flange. The mounting piece 11b has a length substantially equal to the width dimension of the panel 5c, and the supporting surface 11d of the supporting piece 11c is set to be at the same level as the upper surfaces of the girders 3, 4.

In this embodiment, as the fixing piece 11a, a chevron steel having a flange height of 50 mm and a thickness of 6 mm is used.
The mounting piece 11b has a flange with a height of 65 mm and a thickness of 6 mm.
The angle steel is used. Then, at both ends of the fixed piece 11a cut into a length approximately equal to the width dimension of the pillar 1, the tip of the flange portion of the fixed piece 11a (the contact portion with the upper surfaces of the girders 3 and 4) and the mounting piece.
Placement piece 11 so that the level of support piece 11c of 11b becomes equal.
b is arranged and fixed by welding.

Therefore, a step of 6 mm occurs between the tip of the flange portion of the fixed piece 11a and the lower surface of the mounting piece 11b, and the upper surface of the fixed piece 11a and the tip of the flange portion of the mounting piece 11b. There is a 9 mm step between them. These steps are the support hardware
If a gap occurs when fixing 11 to the large beam 2 with a column rigidly connected to the column 1 and the large beams 3 and 4, the flanges 3a of the large beams 3 and 4,
4a to improve work safety or support metal
11 has a function of engaging the side surface of the panel 5c when the panel 5d is placed, and improving the work safety.

The supporting metal 11 is a fixed piece in advance at the factory stage.
It is supplied as a rectangular component by welding the mounting piece 11b to the 11a, and at the construction site, the fixing piece 11a is welded and fixed to the connection portion of the beam 2 with columns and the beams 3 and 4 rigidly contacted with the column 1. Only done. For this reason, it is possible to make a great rationalization as compared with the work of fixing the conventional raising member on the girder.

When the pillar 1 is arranged on the wall portion of the building, the girders 3 are arranged along the wall. In this case, the supporting metal 12 shown in FIG.
Is attached. As the supporting metal piece 12, the same fixing piece 11a and mounting piece 11b as the members constituting the supporting metal piece 11 are used.

However, the panel 5c placed on the support metal 12
Since only one side of the metal piece 12 is mounted, one mounting piece 11b
The support piece 11c is protruded and the other mounting piece 11b is welded in a state where the flange portion of the other mounting piece 11b is arranged on the upper surface side of the fixed piece 11a.

In the supporting metal member 12 configured as described above, the mounting piece 11b having the flange portion arranged on the upper surface side of the fixing piece can function as a ruler angle when the wall panel 13 is attached to the body.

When the supporting metal 11 is fixed to the connecting portion of the pillar-shaped girder 2 of the pillar 1 and the girders 3 and 4, the supporting piece 11c projects from the flanges 3a and 4a of the girders 3 and 4 in the direction of the beam 6 facing each other. To do. For this reason, the girder 3 should be placed in correspondence with the mounting position of the support hardware 11.
The panel 5c disposed between the beam 6 and the beam 6 has the same width and thickness as the panel 5a, and is formed to have a length shorter than the length of the panel 5a according to the protruding length of the support piece 11c. It Then, one end of the panel 5c is placed on the support piece 11c of the support hardware 11, and the other end is attached to the flange 6a of the beam 6.
And the adjacent panel 5a which is placed on the floor form a floor surface.

At the mounting portion of the support hardware 11, the girder 3,
The four flanges 3a, 4a are substantially raised by the height of the fixed piece 11a. For this reason, the panel 5d placed on the support metal 11 has a width equal to that of the panel 5b (a width equivalent to that of the pillar 1) so that the upper surface of the panel 5d when mounted on the metal support 11 is at the same level as the upper surface of the panel 5a. It is formed and is thinner than the thickness of the panel 5b by the height of the fixing piece 11a.

On the flanges 3a and 6a of the girder 3 and the girder 6, there are arranged mounting fittings 14 which have a function of securing a hanging allowance for the mounted panels 5a and 5c and preventing displacement during an earthquake. The mounting member 14 has a long piece 14a and a short piece 14b which are formed by a member bent in an L shape. Grooves 14c into which the flanges 3a and 6a of the beams 3 and 6 are fitted are formed at the base of the long piece 14a and the short piece 14b, and the upper end of the long piece 14a extends horizontally on both sides of the piece 14a. Each bent locking piece 14d is formed.

The groove 14c formed in the long piece 14a is for inserting the flanges 3a, 6a of the large beam 3 and the small beam 6 to define the position of the short piece 14b in each of the beams 3, 6. The short pieces 14b regulate the positions of both ends in the longitudinal direction of the panel 5a placed on the large beam 3 and the small beam 6, and the ends of the panel 5c placed on the supporting piece 11c and the small beam 6 on the small beam 6 side. The position of the part is regulated. Further, a locking piece 14d formed on the long piece 14a
Has a function of facing the grooves formed in the longitudinal direction of the panels 5a, 5c and preventing the panels 5a, 5c from rising when any external force acts on the panels 5a, 5c.

Next, the panel 5 is attached to the body composed of the above-mentioned members.
The procedure for attaching a to 5d will be described. Connect the girders 3 and 4 to the girder 2 with the pillar 1 and the girder 6 to the girder 4.
And the structure of the building is formed. Then, from the pillar 1 to the panel 5a, at the connecting portion between the pillar-mounted girder 2 and the girders 3 and 4 of the pillar 1.
The supporting metal piece 11 is arranged at a position corresponding to the width dimension of 5c, and the fixing piece 11a of the metal piece 11 is welded and attached to the flanges 3a and 4a of the beams 3 and 4, respectively.

The panel 5d is placed on the fixed piece 11a of the supporting metal 11 attached to the girders 3 and 4, and the beam 4 is placed on the girder 4.
The panel 5b is arranged in the direction of. Next, girder 3 and girder 6
Mounting brackets 14 are attached to the flanges 3a and 6a from the side of the column 1 and both ends of the panel 5a are placed on the beams 3 and 6, respectively. At this time, the mounted panel 5a has its longitudinal end defined by the short piece 14b of the mounting member 14, and the locking piece 14d is arranged so as to face the groove formed in the longitudinal direction of the panel 5a. .

Next, a new mounting member 14 is attached to each beam 3 and 6 and a new panel 5a is disposed adjacent to the panel 5a which is already disposed, and a new mounting member 14 is attached to each beam 3 and 6. Install.

Since the supporting metal 11 is attached to the connecting portion between the large beam 3 and the large beam 2 with the pillar 1, the length corresponding to the distance between the supporting piece 11c and the small beam 6 in this portion is set. The panel 5c is mounted with one end mounted on the support piece 11c and the other end mounted on the beam 6, and then a new mounting bracket 14 is mounted on each beam 3,6.

By repeating the above work, it is possible to form the floor surface by the rectangular panels 5a to 5d. Then, after laying the panels 5a to 5d on all the floor surfaces, the joints formed between the panels 5a to 5d are filled with cement mortar so that the frame and all the panels 5a are
It is possible to increase the rigidity of the floor surface by integrating 5 d to 5 d and further finishing all the surfaces of each panel 5 a to 5 d with cement mortar.

In the above embodiment, the mounting bracket 14 is used to define the longitudinal ends of the panels 5a and 5c and prevent them from rising. As described above, the mounting bracket 14 is not previously welded to the large beam 3 and the small beam 4 at positions corresponding to the width dimensions of the panels 5a and 5c.
It is attached to each beam 3 and 6 at the same time as laying a and 5c. Therefore, when the panels 5a and 5c are laid, the beams 3 and 6 do not have protrusions such as the slab plate in the related art, and safe work can be performed. Furthermore, the mounting member 14 is simply the flanges 3a, 6a of each beam 3,6.
Since it is attached by fitting the groove 14c into the groove, the work is simplified, and it is possible to improve the work efficiency together with ensuring the safety.

[0044]

As described above in detail, in the roof / floor panel mounting structure according to the present invention, the protrusions at the connecting portions between the columns and the girders are avoided by the supporting metal, and the roof / floor is attached to the metal. A panel that is thinner than the panel is placed. For this reason, it is possible to avoid the protrusion without providing a raising member on the girder as in the prior art. Therefore, it becomes possible to secure the floor height and lower the eaves height.
Features that can reduce the weight of the building and the amount of steel used by reducing the steel required for the conventional raised material and the steel required for the main pillars and studs that correspond to the increase in eaves height due to the raised material Is to have.
