Description

[0001]
[Technical field to which the present invention pertains]
The present invention relates to a roof of a middle- and low-rise housing, in particular, a dormitory capable of freely selecting the area under the eaves, a construction method of a gable roof, and a roof structure.
[0002]
[Prior art]
As shown in FIG. 7, the girder roof of a general medium- and low-rise housing is fixed to a girder 53 of a pillar 51, a beam 52, and a girder 53 as a frame (of course, a bundle 54 that supports the roof is necessary) Provided in the part). The dimension from the outer wall surface 59 around the house to the end of the eaves (not shown) of the eave, that is, the eaves protrusion 58 is constant, and the height of the end of the roof is the same everywhere.
[0003]
[Problems to be solved by the invention]
In recent urban areas, there has been a demand for a house that makes the best use of a limited site with many exteriors and restrictions that harmonize with a mature cityscape. I want to build a high-class house on a narrow site with the exterior as a base and a gable roof. At this time, it is necessary to freely combine the protruding dimensions of the bag. For example, when the outer wall surface is just below the boundary line of the site, the size of the ridge should be eliminated or shorter than the size of the ridge on the other outer wall surface. In addition, there is an increasing need to make the outer wall surface on the south side about 1 m or more than 1 m in order to effectively use the space under the eaves.
[0004]
In the above-mentioned conventional houses, in order to respond to such needs, when trying to change the projection size of the fence for each outer wall surface, it is necessary to extend the downhill rafter from the girder with a constant height, so the height of the edge of the fence is high. Saga will be mixed and it will be a very unfavorable house. Moreover, in order to extend the strength upper rafter for a long time, the rafter cross section must be enlarged. There are also many types of rafters. The more types of rafters, the more difficult the problems arise, such as the nose hardware on the roof, the installation of the kite, and the simplicity of processing the eaves. Naturally, the number of parts increases, which causes many problems in terms of cost and labor. Furthermore, from the viewpoint of the living environment, the lighting of the armpit is deteriorated because the tip of the armpit is lowered, and it is an obstacle to ventilation.
[0005]
The present invention provides a design method capable of arranging a roof, in particular, a position of a roof without being constrained by the position of the housing, while freely selecting the projecting size of the housing, even though the height of the roof of the housing is the same. It is.
[0006]
[Means for Solving the Problems]
In the roof erection method according to the present invention, a girder beam is arranged at the outer wall position to determine the frame position, and when securing a desired projecting dimension to the eaves, a take-out beam that matches the projecting dimension of the eaves from the girder beam is provided. Select, place, and support the tip of the nose beam so that it is the same height as the girder beam at the tip of the take-out beam. In addition, it is characterized by forming a dormitory or gable-type roof in which ridges having the same height at the heel tip and different ridges are mixed by suspending the nose tip beam or a girder beam also serving as the nasal tip beam. To do.
[0007]
The roof structure according to the present invention is in the form of a dormitory or gable, and is a nose tip beam or a nose tip that is the same height as the girder beam supported at the tip of the take-out beam arranged at the tip of the eaves and taken out from the girder beam A rafter tip portion is hung on a girder beam that also serves as a beam, and a ridge having the same height at the heel tip and different projecting dimensions is mixed.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 is a diagram of one embodiment showing the design, construction and roof structure of the present invention, FIG. 2 is a detailed view of the first outer wall surface side of FIG. 1, and FIG. 3 is the second outer wall surface of FIG. FIG. 4 is a detailed view of another embodiment, FIG. 5 is a view of an embodiment showing the relationship between the exterior wall surface of a house and the tip of a fence and a roof plan, and FIG. 6 is another implementation. It is a detailed figure at the time of minimizing the protrusion dimension of an urn in an example.
[0009]
FIG. 1 shows a cross section of the house from north to south. The first outer wall surface 11 is on the north side, and there is no room on the site, so that the projecting dimension of the kite, that is, the dimension from the outer wall surface to the tip of the kite (omitted in all the following figures) cannot be taken much, and is an example of about 85 cm. . The second outer wall surface 12 is on the south side, and the ridge length is about 207 cm in order to make the eaves under a roofed veranda.
[0010]
In designing, first, the position of the housing is determined, and the take-out beam 17 having the projecting dimension of the housing is arranged on the north side from the girder 3 on the first outer wall surface 11 side of the first housing 15. Next, the 1st nose tip beam 13 is arrange | positioned at the front-end | tip. A second nose tip beam 14 is disposed at a position that becomes the roof tip of the south veranda that is an integral multiple of the module from the first nose tip beam 13 and that is on the opposite side of the house. Then, the take-out beam 17 is arranged on the beam 3 of the second casing 16. Then, rafters are built.
[0011]
In this way, at least the projecting dimension of the northern side can be freely selected. That is, it becomes possible to determine the layout of the roof regardless of the layout of the frame.
[0012]
As shown in the drawing, since the beam 3 of the first casing 15 and the beam 3 of the second casing 16 are arranged at the same height, the take-out beams 17 arranged on these beams 3 are the same. Therefore, the height of the nose tip beam 14 arranged at the tip of each carry-out beam 17 is also equal. That is, regardless of the length of the carry-out beam 17, the heights of the ridges are equal.
[0013]
In particular, the projecting dimension of the fence from the casing is not constant in each direction, and the center of the roof does not coincide with the center of the casing as shown in FIG. 5 and FIG. In other words, by designing the roof without being tied to the center of the frame and the center of the roof, a roof with the same height is used as a reference regardless of the layout of the frame. It became possible to arrange.
[0014]
In this case, if the length of the carry-out beam is set to a dimension that is an integral multiple of the module, the whole can be configured by the module. If several kinds of take-out beams are prepared in advance and the one that meets the needs is used, the number of parts is reduced, which is advantageous for design and construction. Practically, it is better to prepare 4-5 kinds of take-out beams with a protruding dimension of about 60 cm to 180 cm. In this embodiment, the module is 30.5 cm, and the length of the takeout beam, that is, the distance between the beam and the nose beam is an integral multiple of the module.
[0015]
If it is desired to make the projecting dimension of the north ridge as small as possible, the beam of the first skeleton 15 may serve as the first nose tip beam 13 and the takeout beam 17 may be omitted. In this case, the protruding dimension of the ridge is approximately 24 cm. An example of this is shown in FIG. Then, the leading end of the rafter 5 is built on the takeout beam 17 or the nose tip beam 13 attached to the takeout beam 17 and finished as a roof. The rafter may be a rafter of a panel composed of a plurality of rafters, or a rafter of a panel composed of a rafter and a face material.
[0016]
FIG. 2 shows details of the north side of FIG. The frame has a beam 2 and a girder 3 fixed to the side of the column 1. Further, a take-out beam 7 is fixed to the column 1 or the beam 3 and a nose tip beam 6 is fixed to the tip thereof. The bundle 4 is fixed to the beam 2 and the nose tip beam 4, and a rafter 5 is further hung on the beam. The ridge at the tip of the rafter 5 is the heel tip, and the dimension from the outer wall surface 9 is the protrusion dimension 8 of the ridge.
[0017]
FIG. 3 shows the details of the south side of FIG. 1, the contents are the same as those in FIG. 2, and the length 8 of the heel and the length of the take-out beam 7 are different. In this example, the bundle 4 is not at the tip of the rafter 5.
[0018]
4 is substantially the same in size and configuration as FIG. 2, but the structure of the frame is a beam in which the beam 2 and the take-out beam 7 are integrated on the column 1. This is more advantageous in construction than retrofitting the takeout beam, and the number of parts can be reduced.
[0019]
FIG. 5 is a plan view of a house, and FIG. 5 (a) shows a house in which the relationship between the tip 10 of the heel and the outer wall surface 9, that is, the protruding dimension 8 of the heel varies depending on the location of each outer wall surface. It also shows. The ridgeline 18 of the roof shows that it consists of a ridge and a valley.
[0020]
FIG. 2B shows that the outer periphery of the heel tip 10 can be rectangular (shaped) even if the outer wall surface 9 has a complicated shape. That is, according to the present invention, the roof can be simply shaped no matter how complicated the outer wall surface of such a frame is. In this example, the ridgeline 18 has a very simple roof with no valleys.
[0021]
FIG. 2C is an example of a floor plan in the wall surface. In short, it is an example of a flat surface of a house that achieves the above-mentioned problem by changing the protruding dimension of the heel while keeping the height of the heel tip equal.
[0022]
As can be seen from this example, the flat surface of ordinary houses is rarely rectangular, that is, the outer wall surface is 6 or more, and with this, there are often 3 or more types of salvage dimensions. Applying the invention is advantageous for design and construction.
[0023]
FIG. 6 shows an embodiment where the takeout beam is omitted in the description of FIG. In short, the girder 3 also serves as the nose tip beam. Such needs are extremely high in urban areas.
[0024]
In addition, although the said example demonstrated based on the steel-frame-type house, this invention is applicable also to wooden construction. However, in terms of the strength of the material, it is more advantageous to apply it to the steel frame system. The present invention can be applied to a dormitory and a roof of a gable, but it is a dormitory that makes it easy to exert an excellent aesthetic effect by making the tip of the ridge the same height.
[0025]
【The invention's effect】
According to the roof erection method and the roof structure of the present invention, it is possible to freely combine the protruding dimensions of the fence while keeping the height of the edge of the fence the same, so that the limited site can be utilized to the maximum, and aesthetically pleasing. Is not inferior at all.
[0026]
In particular, according to the present invention, the roof can be shaped into a desired shape, so that the roof is large and the building can be seen dignified, which is advantageous in terms of aesthetics. In addition, the roof structure can be simplified, and the valley portion, which is a weak point in the waterproof surface of the roof, can be reduced or eliminated, so that the house can be free of waterproof defects. As a result, it becomes possible to provide durability.
[0027]
The present invention can solve all the problems described in the above problems. In other words, it is technically superior in construction, structure, etc., and having several types of heel protrusion dimensions without changing the height of the heel depends on the length of the heel protrusion dimension. In addition to being able to do it well, we can provide housing that meets the needs of future housing such as aesthetics.
