Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a horizontal roof roof in which a face plate is installed on metal rafters via a base material.

[Conventional technology]

Conventionally, as shown in Fig. 8, for the horizontal roof as described above, a base material (2) made of wood wool cement board or the like is laid on the metal rafters (1) on the right side of the slope. 2)”:
In general, a plurality of face plates (3) made of metal plates such as painted steel plates are disposed in engagement with each other and horizontally roofed in a step-like manner in the direction of one eaves, that is, scaled.

[Problem that the invention seeks to solve]

In the conventional horizontal roof as described above, an almost right triangular space (4) is formed between the face plate (3) and the base material (2), and the space part (4) is formed between the face plate (3) and the base material (2). As shown by the chain line in the figure, the middle part of the face plate (3) in the width (one building) direction is elastically deformed in the inward and outward directions, and rainwater enters inside from the engaging part (3a) of the face plate (3), causing rain to leak. Sometimes.

Therefore, it has been proposed that a synthetic resin foam material with a right triangular side cross section is interposed in the space (4) to prevent elastic deformation of the face plate during strong winds and rain.
The foam materials are easily combustible in the event of a fire, and moreover, they generate toxic gases when burned, so administrative guidance is being directed toward abolishing their use. Furthermore, it is conceivable to interpose flame retardant or noncombustible materials such as wood wool cement boards or foamed concrete boards in the space (4), but there is a problem in that it is difficult to make the side section a right-angled triangle, which is problematic in terms of productivity. There is a point.

The present invention solves the above-mentioned problems, uses flame-retardant plates and non-combustible plates of equal thickness, and is easy to install. The base material is placed in close contact with the base material to prevent the face plate from elastically deforming during strong winds and rain.
[The purpose of the present invention is to provide a horizontal curtain plate that prevents rain and ice from penetrating inside.

[Means for solving problems]

In the horizontal roof of the present invention, a base material made of a flame retardant board such as a wood wool cement board or a noncombustible board and having a width that is the same as or similar to the width of the face plate is placed between the metal rafters having a slope in a step-like manner in the direction of the eaves. The eave side ends of these base materials are indirectly supported by the rafters, the ridge side ends of the base materials are directly supported by the rafters, and a retaining part is provided on the side of the young T eaves from the stepped part of the base material. The face plate is arranged horizontally in a step-like manner in the direction of the eaves, and the outer surface of the base material is brought into close contact with the inner surface of the face plate.

[Effect]

In the horizontal roof according to the present invention, the eave-side end of the base material is indirectly supported by metal rafters having a slope, and the ridge-side end of the base material is directly supported by the rafter, so that the base material is moved in the direction of the eave. Because it is arranged in a stepped manner, even if the base material does not have a right triangular side cross section and is made into a plate with each part having the same thickness, the inner surface of the face plate and the outer surface of the base material, which are horizontally stepped in the direction of the eaves, can be By supporting the face plate with the base material and preventing it from elastically deforming inward during strong winds and rain, it prevents rainwater from entering the inside through these retaining parts due to the elastic deformation of the face plate. In addition, the base material is plate-shaped, and it is highly productive even if it is composed of flame retardant plates and noncombustible plates, and the size is determined by the length of the space between the nails and the width of the face plate. Because it is relatively small and has a width that is the same as or similar to that, it is easy to handle, and a horizontal roof can be obtained at low cost.

〔Example〕

Below is an example of the present invention! This will be explained with reference to FIGS. 1 to 3.

In Figures 1 to 3, (5) is made of C-shaped steel.
This is a J building, and an inner base material (6) made of wood wool cement board is laid on the main building (5), and on the inner base material (6), it extends in the direction of the eaves in a direction perpendicular to the L house (5). Metal 6 trees (1) are supported with a slope, and these rafters (1) are connected to the main building (5
) is fixed by appropriate means. The rafter (1) is.

It is configured in the shape of a vertical hat with a cross-section, a locking piece (1a) is provided on the upper surface (lc), and the ridge side end of the base material (7) is directly supported on both side flanges (lb). The eave side end of 7) is overlapped on the ridge side end of the base material (7) adjacent to the eave side and is indirectly supported by the flange (1b), and the base material (7) is stepped in the direction of the eave ridge. It is arranged in a shape. Also,
The base material (7) is configured to have a thickness #gW at each part, which is T larger than the width W in the eave ridge direction of the face plate (3), which will be described later. The locking piece (
The hanger (8) is fixed on the rafter (1) by la), and the first eave side plate (3) and the adjacent ridge side plate (:3) are attached to the eave from the stepped part of the base material (7). On the side, attach the hanger (8
) is engaged by conventionally known means, and the engaging portion (3
It is horizontally roofed in a step-like manner (scale roofing) in the direction of the eaves with step a). In addition, the face plate (3) is made of a metal plate such as a painted steel plate, and the inner surface of the first face plate (3) and the base material (7
) has almost no gaps on the outside ′? r: Touched. Although not shown, the base material (7) at the eave side end is supported by the rafters via appropriate support members.

Hereinafter, in the A-roof of one embodiment constructed as shown in (G), the length of one base material (7) is equal to the dimension in the opening direction between the rafters (1), and the width in the direction of the eave ridge is equal to that of the face plate. The width dimension is almost the same as (3), and it is a relatively small rectangular plate with the thickness between each part.

It is easy to handle when constructing a horizontal roof, and the base material (7) is made of wood wool cement board, and the 8 parts are the same thickness and there is no weak part, so the face plate can be placed on top of the base material (7). (3) can be used for roofing work, so construction is easy, and the base material (7) can be a regular plate-shaped material, so it is more productive than one with a right-angled side cross section. Furthermore, since the inner surface of the face plate (3) is in contact with the outer surface of the base material (7), if the face plate (3) tries to elastically deform inward during strong winds and rain, the base material (7) ), and the face plate (3
) can be prevented from elastic deformation of the face plate (3) due to this elastic deformation.
) can prevent rainwater from entering through the engagement n (3a), and the source material (7) absorbs and blocks rain water,
It gets smaller indoors. As shown in Fig. 3, a groove-shaped gap is formed in most of the eave direction between the ends of the first panel (3) in the frontage direction, so most of the 18 hand members (not shown) are inserted into the gap. It is possible to connect the opposing ends adjacent to each other in the frontage direction, and the appearance is good because the lintel members etc. do not protrude too much upward.

Figure 4 shows unreleased I! In FIG. 4, which shows another embodiment of I+, the same reference numerals as in FIGS. 1 to 3 indicate corresponding parts. An F-shaped support fixed on the flange (lb) of In this embodiment, the support member (3) is brought into contact with the upper part of the end surface of the rafter (1).
By changing the height protruding from the flange (lb), the degree of freedom in the slope and step of the first plate (3), and the thickness of the base material (7) can be increased, making it easier to design a horizontal roof.

(10) is a space with a substantially triangular side surface formed at the bottom of the base material (7), and if necessary, a reinforcing material formed by bending a metal plate is provided in this space (10). An auxiliary base material (11) may be laid.The structure of this embodiment other than the above-mentioned is almost the same as that of the embodiment shown in FIGS. 1 to 3.

FIGS. 5 to 7 show modified examples of metal rafters used in the present invention. The rafter (1) shown in FIG. Groove (Is)
was formed. The rafter (+) shown in Fig. 6 has a step (1f) in the middle of both side plates (ld), and these steps (
1r) indirectly supports the eave side end of the base material (7) and directly supports the ridge side end, creating a heat insulating space (lO) between the base material (7) and the inner base material (6). It was formed. In addition, a vertical hat-shaped support plate (11) is fitted to the top of the rafter (1) shown in Fig. 6.

By supporting the base material on the flange (lla) of the support plate (11), a thin base material can be used. The one shown in Fig. 7 has a concave groove (1B) similar to that shown in Fig.
).

In the present invention, the base material is not limited to the wood wool cement board, and other flame-retardant boards or noncombustible boards such as foamed concrete boards may be used, and the side cross section formed between the base material and the inner base material An auxiliary base material made of a flame retardant plate or a noncombustible plate may be interposed in the right triangular space.As the auxiliary base material is not required to have high precision and rigidity, it should be placed closely inside the face plate so that the side cross section is right angle. Productivity is better than triangular base materials.

〔Effect of the invention〕

As stated above in theory 15j, tree 9. According to the application, the eave-side end of the base material is indirectly supported by metal rafters with a slope to the right, and the ridge-side end of the base material is directly supported by the rafter, so that the base material is shaped like a staircase in the direction of the eave ridge. Therefore, even if the base material does not have a right-angled triangular side cross section and is made into a normal board shape with a thickness between each part, the outer surface of the base material should be closely aligned with the inner surface of the face plate that is horizontally ruled in a step-like direction in the direction of the eave. By supporting the face plate with the base material to prevent elastic deformation during strong winds and rain, it is possible to prevent water from entering the interior through the retaining part of the face plate. It is relatively small in size, with a length that is the same as or similar to the width of the face plate, and a length that can be installed between the rafters. Therefore, it is easy to handle, and therefore a horizontal JY roof can be obtained at low cost.
