Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a horizontal roof structure that can be successively J1 from the building side to the eaves side, and in particular, it relates to a horizontal roof structure that can be successively J1 from the building side to the eaves side. The present invention relates to a roof structure suitable for a roof using as a face plate.

(Conventional technology J L to dohe, that is, the roof structure in which the face plates are roofed sequentially from the ridge side to the eaves side, is different from the conventional roof structure in which the face plates are roofed from the ridge side to the eaves side. Compared to the method, there is no need to perform the N1-joining of the ridge finish by on-site construction, and the loading of materials is carried out sequentially from the finishing point r11!, making it easier to perform construction. Since the final point -r is not stepped on again, it is particularly suitable for construction methods that use a thin metal sheet as the face plate, which is easily damaged and deformed.

[Problem that the invention seeks to solve]

However, with this construction method, when connecting the 1m board on the roof side to the upper side panel, the spacing structure must be centered in comparison to the conventional method of roofing from the bottom to the roof. There was a fear that this would cause difficulties in the Yukihana at T.

In other words, if the ribbed structure is made into a rough maze-like shape, it will provide good rain protection, but it will be difficult to join. Additionally, because the connection is simple, the face plate tends to swell due to negative pressure caused by strong winds.

Furthermore, if the face plate is made of a thin plate of copper or stainless steel to take advantage of the various construction methods, the face plate itself will deform during construction or transportation, making handling extremely troublesome, especially in strong winds. Installation work was extremely difficult, and in extreme cases, damage such as bending or twisting occurred.

Of course, it would be possible to increase the material thickness of the face plate itself, but in this case the material cost would be extremely high.

This development '71 was made to solve the following problems: the direction of rain fall at the joints of thin metal face plates, and the prevention of floating L during strong winds. and to improve workability.

[P stage for solving problems]

In order to achieve the above-mentioned objective [-1], this invention sequentially lays the face plates constituting the ridge plate from the ridge side to the eaves side, connects the joint edges of each face plate by fitting, and A roof structure in which the inset part is fixed by a suspension f fixed on the side of the eaves rather than the inset part, and a reinforcing plate formed in approximately the same shape as this on the surface of the face plate is damaged. This is the summary.

[Effect]

Since the face plate maintains its shape according to the shape of the face-beaten reinforcing plate, it becomes easy to handle during application. In addition, the dual structure of the reinforcing plate and the face plate prevents rain damage, and even if the face plate is blown by strong winds, the reinforcing plates work together to provide buoyancy, so the face plate does not swell due to strong winds. do not have.

〔Example〕

Hereinafter, one embodiment of this invention will be explained in detail using drawings.IJ
Do 1.

Figure 1 is a cross-sectional view showing a horizontal roof structure according to the present invention.

In the figure, (1) is a main building made of a C-shaped channel-shaped metal workpiece, and (2) is fixed to a part of the main building (1) by bolting, welding, etc., and extends from the eaves side to the ridge side. It is a 1F tree with a hat-shaped cross section that slopes downward at a predetermined slope, and the rafters (2) and the ItJ roof (1) constitute the roof supporting material.

On the rafter (2) L, a board (3) such as insulation material, shielding material, or wood wool board, which has a wedge-shaped cross section and is elongated in the direction perpendicular to the plane of the paper, is attached from the eaves side. It is fixed with a predetermined step towards the ridge side.

The reinforcing plate (4) and its l u
The face plate (5) is tightly attached to M.

For example, the L 4111i strong board (4) is 11! Thickness of lead-plated steel plate: 1. It is made of a press-formed product with an expansion level of Svr. The one-sided plate (5) is made of a press-molded copper plate or stainless steel with a thickness of about 0.4 layers, and its shape is as shown in FIG.
(10) and is formed with an inset part (8) that can engage with the inset part (6t) of the face plate (5), so that the reinforcing plate can be moved in the direction of the eave ridge depending on the safety. Ribs (4a) are formed.

By lining the face plate (5) with this 411ti strength & (4) in advance, the flexibility of the face plate (5) due to its material and thickness is corrected, and a certain degree of rigidity and shape retention are provided. .

The eave side edge of each face plate (5), that is, the eave side edge 11 and the ridge side edge, respectively, have an inset part (if), (7) that engages with each other.
) are formed on the upper and lower edges of the reinforcing plate (4), and as described above, an inset part (8) having a similar shape to the above-mentioned insets fl (8) and (7) is formed.

(3) is formed.

1: Insert the face plate (5) and reinforcing plate (4) that fit together! ! ! ! (8), (8), (7), (9)
The same is fitted with a flap at the front edge of each board (3J), and this flap part is fixed in a state surrounded by a hanging f-(10) fixed to the nail tree (2). There is.

This joining structure is shown enlarged in Fig. 2, of which the face plate (
5] Lower edge fitting ffB (G) is a U-shaped part (
6a) It has a hanging part (6f), a water + part (8g), and an extension part (6b) extending horizontally inward from this part. Further, the lower edge fitting portion (8) of the reinforcing plate (4) is located inside the U-shaped portion (6a) and has the same U-shape as the U-shaped portion (6a).

The 1-edge fitting part (7) of the curve & (5) is a step-like step fl (7a) that is joined to the F side of the core: shaped part (6a) and the water'+ part (6b). :N! 17, @'F part (7F), book+1 part (7g), and a holding part (7b) folded back from the step part (7a). ) The [-edge fitting portion has a stepped shape similar to the step portion (7a).

And, by engaging the turtle part (6f) and the shell part (7f), even in strong winds and rain, the landscape can be
Experiments have proven that there is very little city water that gets blown away along the straight, flush engagement surface, and that enters the inside of the ridge. Namely, Jingki Kiwabe (6g) and (7g)
Since the joints with the top plate are closely connected in a step-like manner, even if some rainwater infiltrates into the interior due to capillary phenomenon, the joints on each face plate are tight and the top of each face plate is tightly connected. Due to the presence of the space (70), the rainwater is absorbed, and the risk of rainwater T entering in strong winds and rains is almost completely eliminated by the joint structure and gap structure of the face plate shown in L. It is possible to eliminate the problem to a near state.

The shape of the seams to the north can be obtained by drawing both ends of the long plate, which is the forming material for the face plate (5) and the reinforcement & (4), in the longitudinal f direction, using a roll forming machine or the like.

The suspension f (10) is attached to the river water (2) on the front side of the gap assembly position and is fixed to the gap part of the face plate (5), that is, at a position closer to the eaves than the gap assembly position t. 111ffi (
IOa), a 1R-L ridge 1 (10b) which is bent from the rear part of the mounting cloth 1 (10a) in an almost U-shape, and a kerb 1-L ridge 1 (10b) which is lowered to the tip of the kerf 1-edge (10b), Said reinforcing plate (5)
The U-shaped engaging part (
It consists of IQc).

This installation work is done in advance by inserting the N1 strong plate (4) o and the do edge of the face plate (5) into the connecting part (11) cJ of the hanging j' (10) ) in iK, then ■
Reinforcing the two edges (7) and (9) which have already been fixed & (4) and the edge insert of the face plate (5) ff1 (8
), (8J makes the work redundant. At this time, the extension part (6b) and the holding part (7b) of the face plate (4) act as resistance when inserting, but due to the interlocking shape of both, That's a lot of resistance!The inset is now complete.

In the 411 configuration described in 1- below, assume that rain is blowing with the wind on the opposite side of the roof slope.

In this case, the wind and rain try to enter the interior from the joint surface of the seam part, and the wind is based on the side edge of one building (3 and 1rU board (5)
It generates a moment that pushes down. Since the plate III (5) is not thick enough, it tends to swell due to the moment, but when the moment is applied to the reinforcing plate (4), it does not swell and becomes a force in the peeling direction. This force can be withstood by the low resistance caused by the seam 311 of the reinforcing plate (4) on the side of the door and by the support provided by the hanging r-(10).

In addition, the hanging (-<IQ) cn mounting surface 1 (10a) is
Since it is located at the toe part rather than the l part, the stronger the pushing force is, the lower the drag force due to the moment in the F direction is produced, further increasing durability.

- The raindrops that entered from the junction m1 are HAZE M! The labyrinth created by the rain prevents the rain from escaping for 1 hour, but the raindrops that get over this will enter the gap between the reinforcing plate (4) and ++r+& (5), and the L side of the reinforcing plate (4) will be blocked. 1
It flows out to the lower side along the m-root gradient.

In addition, in the above embodiment, MIi! The l plate (4) is designated as f&, but by forming a plurality of reinforcing beads (4d) along the roof slope direction on the reinforcing plate (4) as shown in Fig. 3, the face plate (5) This is more preferable because it can provide a reinforcing effect and at the same time reduce the size of the gutter. Furthermore, the horizontal width of the reinforcing plate can be increased depending on the purpose of use.

〔Effect of the invention〕

As explained in detail in the following two embodiments, according to the present invention, on the surface of the face plate constituting the horizontal 1-inch J root material, which has a relatively thin wall thickness, is formed in approximately the same shape as this. By attaching the reinforcing plate to the surface, it becomes easier to handle the plate and there is no damage or deformation caused by external forces.On the other hand, this invention also reduces the cost of materials because the generally expensive face plate can be replaced. It can be done cheaply.

In addition, it has good rain protection during construction, prevents the face plate from bulging τ in strong winds, and makes it possible to realize a 41'J roof with a comprehensively dredged structure.

It is clear from the record that the purpose of the record 151 was effectively achieved. Furthermore, since changes can be made to the structure of the L notation without departing from the spirit and scope of the present invention, the L notation and the precepts are all illustrative examples and should not be construed in any limiting sense. isn't it.

The claims are intended to cover every feature of the invention and all matters within the scope of the invention which may be omitted as a matter of contention.
