Description

[Detailed Description of the Invention] The present invention relates to a dormer mainly used in the field of prefabricated houses.

Conventionally, the construction of a dormer on a roof involves creating a long hole in the roof base plate laid on the roof framework at the appropriate location to install the dormer, and then installing a sleeve post around this long hole. , left and right side plates on the sleeve pillars, roof base plates,
and front panels are attached, and furthermore, external wall materials are placed on the outer surfaces of both side panels with waterproof materials interposed therebetween, and roofing materials are placed on the upper surface of the roof base board with waterproof materials interposed therebetween.

As described above, in conventional dormers, each element is constructed one after another by on-site work, so the number of components is large, the construction process is complicated, and the workability is poor.

In view of this, the present invention aims to provide a dormer that improves workability on site by pre-assembling each part constituting the dormer in a factory.

The configuration of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall structure of the dormer of the present invention. The dormer foundation assembly 11 consists of left and right side wall base plates 2, 3 and a roof base plate 4, which have been preassembled in the factory, and a front decorative panel 5. are attached to form the dormer 1.

FIG. 2 shows the side wall base plate 2 located on the left side of the left and right side wall base plates.

The side wall base plate 2 has a frame 21 assembled in a triangular shape.
A side plate 22 such as a plywood board or a concrete panel is attached to one side, and this frame 2 is attached to the other side.
Spacers 23, 23 are attached along the spacers 1, and a support rod 24 is attached inside the front end portions of the spacers 23, 23.

The side wall base plate 3 located on the right side is shown in FIG. 4, and is constructed symmetrically with the side wall base plate 2 on the left side.

FIG. 3 shows the roof base plate 4.

The roof base plate 4 has horizontal bars 4 between three vertical bars 41, 42, and 43 arranged at regular intervals.
4... are connected and assembled into a chevron shape on a frame 45,
Top plates 46, 46, such as plywood or concrete panels, are attached.

Figures 4 and 5 show each of the above base plates 2, 3, and 4.
This figure shows the state in which the main building materials 61, 62, which are assembled in a cross-shaped structure, are attached to the roof frame by an L-shaped support plate 12 attached to the roof frame 9, so-called cat hardware. It is fixed on 9.

The side wall base plates 2 and 3 are erected facing each other on any pair of the purlin materials 61, 62, etc. arranged in the beam row direction, respectively. That is, as shown in FIG. 4, support rods 24, 34 attached to side wall base plates 2, 3 are inscribed in a pair of purlin members 61, 61, and spacers 23, 33 are placed. It is fixed upright by nailing, etc.

Vertical beams 42 and 43 arranged on both sides of the roof base plate 4 are placed on the upper ends of the side wall base plates 2 and 3, that is, on the frames 21 and 31 and the spacers 23 and 33, and are also formed by nailing or the like. The fixed dormer foundation assembly 11 is assembled on the roof.

A front decorative panel 5 is attached to cover the front ends of both side wall underlayments 2, 3 and the roof underlayment 4 of this dormer foundation assembly 11, as shown in FIG.

Of course, both side wall base plates 2 and 3, roof base plate 4
A field board (not shown) is laid around the front decorative board 5.

In this state, outer wall materials and roof materials are placed outside the dormer foundation assembly 11, and the dormer 1 is assembled.

FIGS. 6 and 7 show how the outer wall material and roof material are installed.

In FIG. 6, the outer wall material 7 whose front end is inserted into the insertion recess 51 provided on the back circumference of the front decorative board 5 is inserted into the side wall base boards 2 and 3 through a waterproof material 6 such as asphalt roofing. side plates 22, 32
It is fixed by nailing etc.

In addition, in FIG. 7, the roofing material 8 whose front end portion 81 is similarly inserted into the insertion recess 51 of the front decorative board 5 is inserted into the top panel of the roof base board 4 through the waterproof material 6.
6 is fixed by nailing etc. In addition, 10 is a ridge wrapper, and the plate piece 13 inserted into the insertion recess 51 of the front decorative board 5 is folded back at the tip to form a drainage board, so that rainwater etc. cannot enter into the insertion recess 51. prevent.

As explained above, according to the dormer of the present invention, both side wall base plates, roof base plates, and front decorative panels, which have been assembled in advance in a factory, are assembled on the roof on site, reducing the number of parts and making the construction easier. Workability can be significantly improved by simplifying the process. In addition, since this dormer is assembled on any pair of roof materials attached to the roof frame, it has excellent practical effects such as being able to select the construction position of the dormer arbitrarily. It is something that you have.
