Abstract

<P>PROBLEM TO BE SOLVED: To solve problems wherein workability is inferior and there are lots of danger such as dropping of a worker on the ground by mistake because the worker performs the work for attaching a roof plate to a skeleton by extending his hand up to a rear side of the roof plate while he faces downward when using an eye deck roof and strength is weak because the roof plate and a tight frame are merely and mutually fitted and attached when using the tight frame. <P>SOLUTION: On the skeleton 7 of a flat roof, a leglike rib part 1 having a roof plate lower face supporting fringe is formed in one end part, and a folding fringe 4 for fitting the leglike rib part or an overlapping fringe 4' of a roof plate lower face supporting fringe is formed in the other end part. The folding fringe is fitted into the leglike rib part 1 or the overlapping fringe 4' of the roof plate lower face supporting fringe is overlapped on the roof plate lower face supporting fringe to connect the roof plates A and fix a connection roof on the skeleton. At that time, it is fixed on the skeleton by a long drilling screw 9 through an oblong hole so as to press by a pressing flat plate 8 forming the oblong hole in the longitudinal direction from above the connection roof. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a flat connection roof that is used as a roof that makes use of a flat surface, for example, in a steel structure or the like, usually using an eye deck, and a construction method thereof.

A flat roof using an eye deck roof in a conventional steel structure or the like has a roof formed by directly attaching the lower ends of leg-shaped ribs to a frame (beam, or main building, etc.) (see, for example, Patent Document 1) Is present.
In addition, there is a folded roof construction method (see, for example, Patent Document 2) in which a corrugated metal roof plate is attached to a frame by a tight frame that is also corrugated.
Japanese Utility Model Publication No. 5-24740 (claim of utility model registration, {action}, {example} in the detailed description column of the invention, FIG. 1, FIG. 4, FIG. 5) JP-A-2001-1219 (claims, detailed description column {0005}, {0006}, {0007}, FIG. 10, FIG. 12)

However, in the above prior art, in the case of the former (using an eye deck roof), an operator usually attaches the lower end of the leg-shaped rib portion of the roof plate directly to the housing by means such as welding or screwing. Since the work is extended from the top of the roofboard to the backside of the roofboard, the workability is poor, and there is a great risk of accidentally falling to the ground.
In the case of the latter (using a tight frame), the roof plate and the tight frame are simply formed by fitting and fitting the same shape into a corrugated shape. When the waterproof structure is provided on the upper surface of the plate, the roof plate is corrugated, so that there are problems such as danger in construction and troublesomeness.

The first invention of the present invention for solving the above-mentioned problems is a flat connected roof as described in claim 1, and is as follows.
On a flat roof frame, a leg-shaped rib portion having a roof plate lower surface support edge is formed at one end, and a bent edge for fitting the leg rib portion or a roof plate lower surface support edge overlapping edge is formed at the other end portion. The connecting roof, in which the bent edge is fitted to the leg-shaped rib portion, or the roof plate lower surface support edge overlapping edge is overlapped with the roof plate lower surface support edge to connect the roof plate is fixed to the casing. When installing, it is a structure fixed to a housing | casing with a long drilling screw through the said long hole so that it may hold down with the presser plate which formed the long hole in the longitudinal direction from the connection roof.

A second invention of the present invention for solving the above-mentioned problems is a flat connection roof as described in claim 2, and is as follows.
2. The flat connected roof according to claim 1, wherein a ceramic-based incombustible plate, a heat-resistant / heat-insulating plate, and a waterproof material are sequentially laminated on the connected roof to form a heat-resistant / heat-insulating / water-proof structure.

A third invention of the present invention for solving the above-described problems is a flat connection roof as described in claim 3 and is as follows.
The flat connected roof according to claim 1 or 2, wherein the ceramic incombustible plate, the heat-resistant and heat-insulating plate, and the waterproof material are integrally fixed by a required fixing means.

A fourth invention of the present invention for solving the above-described problems is a flat connected roof construction method as described in claim 4, and is as follows.
On a flat roof frame, a leg-shaped rib portion having a roof plate lower surface support edge is formed at one end, and a bent edge for fitting the leg rib portion or a roof plate lower surface support edge overlapping edge is formed at the other end portion. The bent edge is fitted to the leg-shaped rib portion, or the roof plate lower surface support edge is overlapped with the roof plate lower surface support edge to sequentially connect the roof plates, and the top of the connected roof plates In this configuration, a roof plate presser plate having a plurality of long holes formed in the longitudinal direction is placed on and pressed by the long case with a long drilling screw through the long hole.

Since the flat connection roof and its construction method according to the present invention are configured as described above, the following effects are achieved.
(1) On a flat roof frame, a leg-shaped rib portion having a roof plate lower surface support edge is formed at one end portion, and a bent edge for fitting the leg-shaped rib portion or a roof plate lower surface support edge overlapping edge is formed at the other end portion. And connecting the roof plate by fitting the bent edge to the leg-shaped rib portion, or by overlapping the roof plate lower surface support edge overlapping edge with the roof plate lower surface support edge. When fixing to the frame, it is characterized in that it is fixed to the frame with a long drilling screw through the long hole so that it can be pressed by a holding plate having a long hole formed in the longitudinal direction from above the connecting roof. Without the installation of the roof plate to the frame by the operator reaching up to the back side of the roof plate in a state of facing downward from the top of the roof plate, as in the construction of a flat connected roof using a conventional eye deck roof, Can be mounted on the roof plate Via the presser plate-only secure the long Doriringuneji the building frame, the leg-shaped rib portion of the presser plate and roof plate, long Doriringuneji, is formed by precursor. It becomes a parallelogram box shape and strength is increased. In addition, the workability is very good and there is no danger of accidental dropping during the work, and the safety is extremely high.
(2) Since a waterproof structure or a ceramic incombustible board, a heat-resistant / heat-insulating board, and a waterproof material are laid in order on the roof board as needed, a heat-resistant / heat-insulating / water-proof structure is formed. A flat connected roof excellent in fire resistance, heat resistance, heat insulation and waterproofness can be obtained.

  On a flat roof frame, a leg-shaped rib portion having a roof plate lower surface support edge is formed at one end, and a bent edge for fitting the leg rib portion or a roof plate lower surface support edge overlapping edge is formed at the other end portion. The connecting roof, in which the bent edge is fitted to the leg-shaped rib portion, or the roof plate lower surface support edge overlapping edge is overlapped with the roof plate lower surface support edge to connect the roof plate is fixed to the casing. When installing, press down the bottom of the roof plate as much as possible so that it will not be lost with a long drilling screw through the long hole so that it can be pressed with a presser plate that has a long hole formed in the longitudinal direction from the top of the connecting roof On a flat connected roof that is located close to the roof and fixed to the frame, a ceramic non-combustible plate, heat-resistant / heat-insulating plate, and waterproofing material are laid in order to form a heat-resistant, heat-insulating and waterproof structure. is there.

  1 (a) and 1 (b) are a front sectional view and a side sectional view showing an example of an assembled state of a flat connection roof, FIG. 2 is a front view of a drilling screw, and FIGS. 3 (a) and 3 (b) are flat connection. It is a figure which shows the presser plate for fixing a roof to a housing, Comprising: (a) is a top view, (b) is a front view, FIG. It is a front view which shows an example, Comprising: (a) shows what formed the bending edge for leg-shaped rib part fitting on the other end side flat surface of a roof board, (b) is the folding for same leg-shaped rib part fitting. FIG. 5 is a partially enlarged front sectional view of a roof plate of a flat connection roof, and FIG. 6 is a heat insulating / waterproof structure. FIG. 7A and FIG. 7B are partially enlarged front views showing other examples of leg-like rib portions.

1 to 5, reference numeral 1 denotes a leg-shaped rib portion having vertical wall portions 1 a and 1 a that are bent on the lower surface of the roof plate A, and is generally 3 for one roof plate A. The book is formed. The leg-shaped rib portion 1 has an expanded bottom portion 2 at the lower end, and the upper ends of the vertical wall portions 1 a and 1 a are bent in a substantially horizontal shape and formed on a flat surface 3. The flat surface 3 at the upper end of the vertical wall portion 1a of the one-end-side leg-shaped rib portion 1 of the roof plate A serves as a roof plate lower surface support edge when the roof plate is connected. 4 is a bent edge for fitting a leg-shaped rib portion formed on the other flat surface 3 of the roof plate A, and 4 'is a roof plate lower surface supporting edge overlapping edge mounted and polymerized on the other flat surface 3 ( Flat extension). Reference numeral 5 denotes a small reinforcing concave / convex portion formed between the leg-shaped rib portions 1 of the roof plate A, and is formed in the length direction of the roof plate A in parallel with the leg-shaped rib portion 1. The cross-sectional shape of the reinforcing concave / convex portion 5 is formed in a trapezoidal shape that continues in the forward and reverse directions as shown in FIGS. 4 and 5, but is not limited thereto. For example, it is needless to say that a small reinforcing concave / convex portion 5 may be formed flat.
The connected flat roof plate is directly screwed into a housing (beam or the like) with a long drilling screw 9 via an elongated holding plate 8, and the flat roof plate is pressed with a holding plate 8 and a long drilling screw 9 as shown in FIG. Since the leg-shaped rib portion 1 and the frame (beam) of the flat roof plate can be held in a parallelogram box shape, the strength is excellent.
The presser flat plate 8 may have a length substantially the same as the width of each flat roof plate A because of the dimensional error of the flat roof plate and the connection of the flat roof plates. Even if there is an error, it can be easily handled. This is because the length of the presser plate 8 is not so long, and therefore the wave is less likely to be hit. Therefore, the long hole 8 ′ formed in the presser plate 8 can sufficiently cope with the flat roof plate A when the long drilling screw 9 is screwed. It is no longer necessary to weaken the strength by biting into the expanded bottom portion 2, so that accurate screwing becomes possible. That is, if the presser flat plate 8 is made long, it swells or a flat roof plate is connected, so that there is a dimensional error and there is a possibility that the presser flat bottom portion 2 may be bitten.
In addition, the position where the long drilling screw 9 is screwed in is located as close as possible to a position where it does not hang on the expanded bottom portion 2 so as not to lose the expanded bottom portion 2 of the roof plate A through the long hole 8 ′ of the holding plate 8. By screwing into the position, as a result, the roof plate A can be made flat without being uneven, and can be formed very flat for post-treatment such as waterproofing, so that water can accumulate even on a flat roof. There is also an effect that there is little.
The waterproof structure formed on the upper surface of the roof plate A is not shown in detail, but is made of an asphalt layer, made of a waterproof sheet such as synthetic rubber or plastic, or a combination of both. Those provided with a heat insulating material such as urethane, polyethylene, rock wool material, etc., or those not provided are appropriately selected depending on the construction conditions of the connected roof.
FIG. 6 shows a heat-resistant / heat-insulating / waterproof structure formed on the top surface of the roof plate A. For example, a ceramic non-combustible plate (not shown) and a heat-resistant / heat insulating plate 6a are fixed on the flat connection roof with fixing screws 10. In addition, the waterproof material 6b is sequentially provided in a laminated form on the upper part.

  In addition, as said ceramic type | system | group noncombustible board, a calcium silicate board, a gypsum board, a wood wool cement board, a glass wool board, a rock wool board, these synthetic boards, etc. can be used, for example, and as the heat resistant and heat insulating board 6a, Can be used, for example, those containing the same quality as the synthetic resin-based plate such as polyisocyanurate and phenol and the ceramic non-combustible plate, and the waterproof material 6b is, for example, vinyl chloride resin or other synthetic resin-based plate In addition to tarpaulins, asphalt tarps, aluminum foil, other metal tarpaulins, rubber, synthetic rubber tarpaulins, stainless steel tarpaulins, lead tarpaulins, colored hot dip galvanized copper sheets, etc. can be used. However, these are appropriately selected and used according to the construction conditions of the connected roof. Reference numeral 7 denotes a frame {beam, purlin, concrete (ALC)}.

  Further, the ceramic incombustible plate, the heat-resistant and heat-insulating material 6a, and the waterproof material 6b can be arbitrarily laid according to the size of the roof, or a plurality of laid sheets, and the fixing means can be, for example, screws, It is integrally attached by a fastening means such as a fastening material such as a needle or an adhesive (not shown).

  At the time of construction, after fixing the ceramic non-combustible plate and the heat-resistant / heat-insulating plate 6a with a fixing material, the polyvinyl chloride coat is melted by heating, and the vinyl chloride resin-based waterproof sheet 6b is laid thereon. It may be attached as a single unit. Since others are the same as those described with reference to FIGS. 1 to 5, detailed description thereof is omitted.

  The cross-sectional shape of the expanded bottom portion 2 of the leg-shaped rib portion 1 of the roof plate A can be a triangular shape, a quadrangular shape, or other various forms as shown in FIGS.

Next, the operation will be described.
At the time of construction, as shown in FIGS. 1 and 6, it is laid on a flat roof frame 7, and a leg-like rib portion 1 having a roof plate lower surface support edge 3 is formed at one end portion of the roof plate A. In addition, a bent edge 4 for fitting the leg-shaped rib portion or a roof plate lower surface support edge overlapping edge 4 'is formed at the other end portion, and the bent edge is fitted to the leg-shaped rib portion 1, or the lower surface of the roof plate. In order to hold the roof plate lower surface support edge overlapping edge 4 ′ on the support edge 3, so that the roof plate A is connected with the press plate 8 having a long hole 8 ′ formed in the longitudinal direction from the top of the connected roof. It is a flat connected roof which is fixed to the housing with a long drilling screw 9 through the long hole 8 'and further laid with waterproof sheets in a laminated form, and the bottom surface of the recessed portion for fitting the leg-shaped rib portion of the tight frame as in the conventional example If the part is directly attached to the beam, etc. by welding, screws, or other appropriate attachment means Further, each leg-shaped rib portion of the roof plate is fitted in the recess for fitting the leg-shaped rib portion of the tight frame, and the expanded bottom portion of the leg-shaped rib portion is formed on the tight frame, and the roof plate. With the concave and convex portions for fitting the tight frame fitted to the concave and convex portions for fitting the roof plate of the tight frame, the abutment portion of the expanded bottom portion and the tight frame and the concave and convex portions for fitting both There is no need to integrally attach them by self-drilling screws, bolts and nuts, or other appropriate attachment means.

Here, the longer drilling screw 9 will be described in detail with reference to FIG.
When the connecting roof A is fixed to the housing 7 (for example, a beam) with a drilling screw 9 having a special sword tip so that tapping can be performed, a screw is provided according to the height of the connecting roof A, and it is appropriate not to be screwed deeply. In order to be able to be screwed into a state, a screw formed with a reverse screw 11 serving as a stopper is employed.
