Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a renovated roof, and in particular to a renovated roof of an existing frame house, in which the roof portion is removed and a new roof with a space for living etc. is installed. .

(Background technology) Repairs to aging houses include replacing and installing window sashes, entrance/exit doors, sliding doors, etc., or repainting the exterior walls, and roof tiles are used to prevent water leakage.
The corrugated iron roofing will be replaced, but only partial repairs will be made.

On the other hand, although the buildings are not necessarily obsolete, due to the demand for increased power, additions to the second floor or extensions to the first floor have been made as extensions and renovations.

However, although the above-mentioned partial repairs result in the part having the appropriate function, it does not lead to the addition of living space.On the other hand, even if an attempt is made to extend or renovate the part, it is impossible to add a first floor in areas where land area is limited, such as in urban areas. Even if it is possible and an attempt is made to add a second floor instead, for example, in the case of an existing one-story house of a few square meters, the construction and cost will be the same as building a new two-story house.

Therefore, in the case of these constraints, one has no choice but to rely on the above-mentioned partial repair or new construction.

(Objective of the Invention) The present invention can be used in this way even in cases where there are restrictions such as in the case of relatively small existing houses in urban areas. l The purpose of the present invention is to provide a renovated roof that is not limited to partial repair, but also enables the addition of living space, etc., and dramatically improves the appearance of the house.

(Structure of the Invention) For the above purpose, as a result of intensive research, the present invention has found that even in the case of an aging existing house, the frame structure of the house still maintains its structural strength. If the building is a frame structure, the existing roof can be removed relatively easily with the effect on the structural strength as small as possible and the part of the house above the existing girders can be removed relatively easily. This invention was completed by removing the roof from the roof and installing a new triangular roof structure with a relatively steep slope using two-by-four (MO) lumbar structural materials, and creating an effective space for living inside. The present invention has already provided a triangular ramper truss in which the bottom joists are longer than the girder spacing of an existing house and have a length that is approximately a multiple of 0.3 meters, and the inclination angle of the left and right barrels is approximately 35 degrees or more. , the existing girder of the existing frame structure house has been removed and exposed, or on the new girder installed as necessary, multiple structures are placed side by side via architraves, and these are connected with purlins, etc. do,
An existing shaft characterized in that a new roof groove structure is installed in place of the existing roof, a roof exterior is applied to the outside of the new roof structure, and the inside of the new roof structure becomes a space with a triangular cross section for living or storage. The gist of this article is the renovation of roofs for houses with built-in construction.

The present invention is aimed at existing houses with frame structures, and actively uses two-by-four lamp structure materials for these frame structures, which are relatively inexpensive and uniform. This is because it is easy to obtain long structural materials. This two-bar four lamper structural material is included in the present invention.

A base joist with a length that is approximately a multiple of 0.3 meters is used as a reference.

This is because many frames-structured houses use the old shaku-kan method as standard dimensions, and the girder spacing of existing houses is often a multiple of 0.3 meters in the old shaku, that is, kane-shaku. The reason why the bottom joists were made longer than the girder spacing of the existing house to be renovated was because, at least, when the triangular ramp truss described later is placed on the girder, the length is 1/2 of 0.3 meters and the girder spacing is centered. (Actually it will be slightly shorter due to the length)
This is to make it possible to provide a river width on both sides that is a multiple of, for example, 0.3 meters on one side.

Then, the left and right barrels are installed at an angle with respect to the bottom joist to form a triangular lumber truss. At this time, the left and right barrels each have an inclination angle of approximately 35 degrees or more, preferably 40 degrees or more relative to the bottom joist. will be installed. Therefore,
Right triangle shape with - side 90 degrees, both sides 45 degrees or 6
An equilateral triangle or an isosceles triangle with an angle of 0 degrees can be arbitrarily selected and installed according to the existing house. In particular, it is not necessary that the lengths of the left and right barrels be approximately multiples of 0.3 meters, but if they are approximately multiples of 0.3 meters, similar to the bottom joists, there will be no restrictions on the arbitrary selection of the slope angle. I'm leaving, but instead,
This is desirable because it allows standardization of lumbar structural materials. Note that depending on the shape or dimensions of the triangular lamber truss, regional building height restrictions may apply.

The existing roof of the existing frame structure house will be removed to expose the existing girders. Of course, this removal involves removing the roof exterior,
Next, the roof structural members are sequentially removed and removed. At this time, since there is generally a lot of dust, it is best to surround the house with scaffolding and sorting. The exposed existing girder may be used as is, or if necessary, a new girder for reinforcement may be placed and fixed, or it may be replaced with a new girder such as VcJ. Note that if a log beam is installed in an existing frame structure house so as to protrude above the girder, it is not possible to remove it as described later.

On the exposed existing girder mentioned above or the new girder whose price has been set as necessary, triangular trusses are placed side by side in a repeated construction pattern via architraves, and these are connected by purlins, external verticals, etc. A new roof groove structure will be installed.

The architrave is generally constructed in a rectangular shape to conform to the existing girder or the new girder, and, if necessary, is constructed by installing reinforcing partitions in accordance with the structure of the existing axis H1 structure house. This architrave can be made, for example, from a minimum height of about 4 centimeters using lumbar structural material, to a maximum height of about 0.3 meters by erecting short studs at a predetermined length between the upper and lower frames. can be generally used. The height of this architrave is determined as appropriate to match the existing house, but elevated ones are particularly effective when log beams are present in the existing frame structure house.

The triangular lumber trusses are connected by purlins, external verticals, etc. to form a new roof structure, and these are fixed using commonly used nails and structural plywood or metal plates.

And, in this triangular Lambert truss, except for those located at both ends, all the parts juxtaposed in the middle are U//
No reinforcing material, such as an M-shaped reinforcing material, should be inserted inside the bar truss in the vertical direction at least in width. Furthermore, since those located at both ends constitute the roof side walls, and structural plywood is usually stretched on both sides, it is desirable to provide reinforcing materials for fixing them as well.

An example will be described below according to the drawings. What is shown in the drawings is an example of a renovated roof 1 using a nearly equilateral triangular lambert truss. The existing girder 4 is removed and the existing girder 4 is used as it is, a triangular lumber truss 7 is installed thereon via an architrave 6, and a roof exterior 9 and a floor 10 are installed.

The bottom joist 71 of the triangular lumber truss 7 is connected to the existing girder 4,
Use all those with multiples of 0.3 meters that are longer than 40 intervals,
In addition, left and right barrel trees 72 and 72 of the same length are each nailed and fixed at an angle of 45 degrees by a gazette plate 73 . . . .

The architrave 6 is of a raised type because the log beam 5 is used in the existing frame structure house 2. That is, a frame 61 is constructed between the upper and lower ramper structural members 62, 62 via short stands 63, and a structural plywood 64 is stretched over the frame 61.

A large number of the triangular lumber trusses 7 are placed in parallel on the existing girder 4 via the raised architrave 6, and are assembled and fixed in a lattice shape by the purlins 74, outer verticals 75, and anti-fall 76, A new roof structure 8 is constructed to replace the existing roof portion 3Vc. Note that the procedure for assembling the new roof structure 8 does not need to be limited to only one method, as the optimal method can be selected depending on the renovation site.

The outside of this new roof structure 8 is covered with a roof sheathing 9 made of galvanized iron, and the inside is covered with a structural plywood floor 10 on the bottom joists.
are stretched to form a space 11 with a triangular cross section for living or storage. Incidentally, although not shown, an opening is naturally provided in the floor surface 10 section t, and it is a matter of course that a staircase from the first floor section or a storage staircase communicates with this opening.

Furthermore, after the renovated roof 1 is installed, the exterior walls of the existing house 2 are covered to match the renovated roof, if necessary.

Although this embodiment has been constructed as described above, the present invention can be implemented in various ways without departing from the gist of the invention.
Each configuration, including the dimensions, the interior interior of the new roof structure, and the type of roof exterior material, is not limited to the above.

(Effects of the Invention) The present invention removes the existing roof of an existing frame structure house, installs a new roof structure in its place, and converts the inside of the new roof structure into a space with a triangular cross section for living or storage. Therefore, not only one-ike houses with small architectural dimensions but also 2
It is possible to add an effective space that is equal to or more than the planar building area at maximum to a multi-story house, etc. Moreover, this new roof groove structure has a triangular shape with a slope angle of about 35 degrees or more for the left and right barrels. By using a lumber truss, you can instantly give an existing house a new look.

It is economical to make use of the existing frame structure by removing only the existing roof and using existing girders or new girders installed as needed.

In addition, since the bottom joists of the triangular Lanhart truss are longer than the girder spacing of the existing house and have a length that is approximately a multiple of 0.3 meters, the new roof structure can be built with a predetermined dimension from the outside wall of the existing house. It can be made to protrude, which is extremely advantageous not only in improving the appearance but also in terms of rain protection, and can support the new roof structure firmly and stably.

Furthermore, since the triangular lumber trusses are juxtaposed and fixed via architraves, their height positions can be adjusted, making it possible to respond to the individual special circumstances of the existing frame structure house.

Furthermore, in the present invention, the new roof structure is integrally fixed to the existing girder integrated into the existing frame structure or to the new girder installed as necessary via the architrave. The roof structure increases rigidity in the groove direction and has the effect of reinforcing the existing frame structure.

As described above, the present invention is not limited to mere partial repair, but is a repair that allows for the addition of space in the same way as an extension, and is a renovated roof that can be easily and reliably performed regardless of restrictions such as land area. be.
