Description

The present invention relates to a method for constructing a roof, and more particularly to a method for constructing a roof with improved transportability and workability.

“Conventional technology” When building a house, there is a conventional construction method in which the roof is constructed together with the skeleton of the living part and the roof is arranged by arranging roof tiles, etc. As a result, many prefabricated houses have been constructed with the roof as a unit to shorten the construction period and stabilize the quality. As an example of such a prefabricated house, the technique disclosed in Japanese Patent Laid-Open No. 62-6041 is known. This technique is to adhere two wall panels to the surface of a supporting frame using a plurality of frame members to form two supporting panels, and to form a surface of a rectangular roof frame formed by a plurality of frame members. A roof surface material is attached to the two to form two roof panels, and side edge portions of the two roof panels are attached to the support portions of the two support panels to form a ridge-side roof unit. To do. In addition, an intermediate roof unit and an eaves-side roof unit are configured similarly to the ridge-side roof unit by using the support panel of the ridge-side roof unit, the support panel formed similarly to the roof panel, and the roof panel. An intermediate roof unit and an eaves-side roof unit are adjacently combined on both sides of the ridge-side roof unit, and the roof surfaces of these roof units are continuous to form one roof.

[Problems to be Solved by the Invention] However, in a house using the ridge-side roof unit and the eaves-side roof unit, the roof unit may be relatively large and may be formed over each living part. However, in this case, there is a problem in that it is disadvantageous in terms of transportation efficiency.
Also, in a house using the roof side roof unit, there has been a problem that it is difficult to align and fasten each roof unit, and the efficiency of on-site work deteriorates.

As a matter of course, the conventional method has a problem that it takes a lot of work and it is difficult to improve work efficiency.

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a method for constructing a roof that improves the efficiency of transportation and the efficiency of field work.

"Means for Solving the Problem" The method for constructing a roof of the present invention divides the roof into a plurality of parts, unitizes each of the four corners and the central part thereof, and forms a roof plate part continuous to these unit parts. This is a method of constructing a roof using a panelized roof panel. First, four corner units and a central unit are arranged at predetermined positions in a house, and then beams are bridged between the units. The roof panel is arranged along these beams.

[Operation] According to the roof construction method of the present invention, the roof is divided into a plurality of parts, and the four corners and the central part thereof are unitized. The roof can be easily and quickly constructed simply by arranging the sub-units at predetermined positions in the house and then laying beams between the units.

Further, since the roof panel is used, it does not become bulky during transportation, and the roof panel is easily and efficiently transported to the site.

[Example] An example of a method for constructing a roof according to the present invention will be described with reference to Figs. 1 to 6. In this embodiment, as shown in FIG. 1, a gable type roof will be described with reference to a method of constructing a roof in which the balcony parts B and B are provided at both ends thereof.

In the roof in this embodiment, the four corners in which the balcony portion B is formed and the central portion are unitized, and the floor portion and the roof plate portion connected to these unit portions are panelized. That is, four corner units 1, 1 ..., a central unit 2, four floor panels 3, 3 ... that are continuous in the length direction of the roof, and two floor panels 4 that are continuous in the width direction, 4 and 4 roof panels 5,
5 ... has been produced in the factory in advance, and will be constructed as follows.

First, the corner unit 1 is a horizontal member as shown in FIG.
6a, a plurality of vertical members 7, 7 ...
... are erected at regular intervals, and a pair of long and short pillars 8, 8 are erected at intervals in a portion facing the inner side of the roof. These pillars 8, 8 and the pillars 8, Beams 9 and 9 are attached to the floor members 6 and 6 at positions corresponding to 8, and a roof panel 10 is attached along the beams 9 and 9 so as to have an inclination. . The vertical members 7, 7 ... Sides are covered with the wall panel 11. The corner unit 1, 1 ... Having such a configuration is arranged at each corner on the floor of the house. And, as shown in FIG. 3, the central unit 2 includes two units 2
It consists of a and 2b, and the unit 2a on the left side of the figure is the central floor 12
And the unit 2b on the right side has a length substantially equal to that of the corner unit 1, that is, the remaining 3/1.

In these units 2a and 2b, a pair of long and short columns 14 and 14 are erected on both sides of a floor member 13 at intervals, and beams 15 and 15 are bridged over these columns 14 and 14, respectively. Mounted on these roofs 15, along with the roof panels 16,
16 are mounted to have a slope. The roof panels 16, 16 are butted at the top and fastened by a metal fitting 17 as shown in FIG. The central units 2a and 2b are manufactured in the factory and connected to each other in the field. That is, the central units 2a and 2b are arranged in the central portion on the floor of the house.

Next, the corner unit 1 arranged at a predetermined position on the floor
And the floor panels 3, 3 ... Are attached to the floor of the central unit 2 so as to be continuous in the length direction of the roof, and the floor panels 4, 4, ... Are connected so as to be continuous in the width direction of the roof.
... are arranged respectively.

The floor panel 3 and the floor panel 4 are also panelized in a factory or the like. The floor panel 3 has the same width as the floor of the corner unit 1 and, as shown in FIG. A frame member 18 and floor beams 19, 19 ... Attached between the frame members 18 are used as a basic structure, and a floor plate or the like is attached to the upper surface to form a floor surface. The floor panel 3 has an eaves portion 20 extending from the frame member 18 to the left in the drawing. In addition, the floor panel 4 includes a portion sandwiched between the floor panels 3 and 3, the corner unit 1,
1 and a portion forming a balcony portion B sandwiched between the two. The floor panel 4 may be unitized so that pillars are erected and walls are formed.

Next, the beams 21, 22, ... Are bridged between the corner unit 1 and the central unit 2, respectively.

Then, the roof panels 5, 5 ... Are respectively arranged along the beams 21 and 22 to complete the construction of the roof. After that, finishing work such as waterproofing of seams is completed to complete the roof.

Like the roof panel 16 of the central unit 2, the roof panel 5 also has frames 23, 23, cross bars 24, 24 ..., and a plate member 25.
Panelized by and.

However, according to the roof construction method having such a configuration, the roof is divided, and the central unit 2 and the corner unit 1 among them are unitized, and the floor panels 3 and 4 and the roof panel 5 connected to them are united. Since it is made into a panel, it can be easily transported to the site along with other units in the living area during transportation.

In addition, the units 1 and 2 are arranged first, and the beams are attached to them.
Since the roof panels 5 and 5 are arranged by bridging 21, 22 and so on, the connection work is simple and the roof can be constructed quickly and reliably. In this case, the units 1 and 2 can be attached and the panels can be arranged from the inside without using a scaffold. Further, in the above-described embodiment, the beams of the ridge are not required, and the beams 21 and 22 are provided in the middle of the flow between the units 1 and 2 to save the members.

In addition, in the said Example, although it has the balcony part B, of course, it can apply even when constructing a gable roof without a balcony part.

It can also be applied to a roof with a combination of gables as shown in FIG. In this case, both ends 23, 23,
The bent part 24 is made into a unit, and the straight parts 25, 25 ...
It is good to make a panel.

"Effects of the Invention" As described above, according to the roof construction method of the present invention, the following respective effects can be achieved.

(1) The roof, which is difficult to construct, is divided into a plurality of parts, and the four corners and the central part are unitized, so at the site, the four corner units and the central part are located at predetermined positions in the house. It is only necessary to bridge the beams between the units after arranging them, and therefore the construction on the site is only a simple connecting work, and the roof can be constructed easily and promptly and accurately.

(2) Since the roof plate part, which is a simple continuous part, is panelized into a roof panel, it does not become bulky during transportation,
