Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a combination of blocks for projecting corner roofs used for assembling various house models.

[Conventional technology and technical issues to be solved]

When constructing a house, we draw up a floor plan of the actual building to be built according to the floor plan, and if necessary, an exterior perspective (completion drawing) according to the exterior plan.
However, creating an exterior perspective not only costs money but also requires a considerable amount of time. In this case, if the construction instructions after the basic design can be shown on a scale model of the actual building, it will be easier for the owner to understand the image of the completed house, and the construction side will also be able to consider the order of construction. This is ideal because it can be done.

However, actually making a model requires much more effort and time than drawing a technical illustration of the expected completion using an exterior perspective, so it is rarely done. The reality is that people are compromising their work by using simple drawings, such as drawings and elevations.

This invention is designed to make it easier to build a house model by combining a minimum of types of blocks rather than creating an exterior perspective as a basic design for various types of houses. The technical problem is to provide a practical residential roof block combination whose parts can be easily assembled and visualized three-dimensionally.

[Means adopted to solve the problem]

In the present invention, roofs for projecting corners can be constructed by connecting chevron-shaped projecting corner roof blocks with diagonal lines as broken lines so that the projected planar shape forms a square at the roof joint forming the projecting corner, extending the broken lines. was completed by focusing on the fact that it could be constructed by simply joining together flat roof blocks, and referring to the attached drawings, the gist lies in the adoption of the following means.

That is, in the present invention, the length of the hook side that sandwiches the right angle is N,
A pair of right triangular plates whose crotch length is N/cos θ, a pair of right triangular plates whose hook sides are kept horizontal, and whose crotch sides are tilted upward by θ° with respect to the hook sides. It is a chevron-shaped block whose chord sides are joined to each other and whose joint diagonals are broken lines, and the hook sides of both triangular plates are provided with a pair of fitting protrusions 11, 11 extending in the extending direction of the hook sides. On the other hand, a pair of groove-like fitting grooves 12, 1 with a uniform cross section are provided on the side surfaces of each crotch side of the triangular plate and are recessed in the depth direction of the crotch side.
The protruding corner roof block 1 is made by drilling 2; It is made of a rectangular flat plate with the length of the long side being N/cosθ and the length of the short side being k (k<N), and both sides of the long side are are provided with fitting grooves 21, 21, and a fitting convex portion 22 is provided on the front short side end surface, and a fitting recess 23 is provided on the rear short side end surface.
The flat roof block 2 is made of a rectangular flat plate with a long side length of N/cosθ and a short side length of k'=(N-k), and a pair of flat roof blocks on both sides of the long side. It is made up of a combination of joint materials 3 each having parallelogram-shaped fitting protrusions 31, 31 protruding; joint materials 3, 3 to one of the fitting protrusions 3
1, 31 are fitted and joined, and the fitting grooves 21 of the flat roof blocks 2, 2 are fitted to the other fitting protrusions 31, 31 of the joint members 3, 3 on both sides, respectively, and joined. At the same time, a trapezoidal convex portion formed by joining the fitting protrusion 11 of the protruding corner roof block 1 and the tip of the fitting protrusion 31 of the joint material 3 is attached to the front protruding corner roof block 1'.

A corner line l-l' is formed at the joint where the roof R2 and the roof _R2 are joined, and cannot be constructed with a flat roof block.

Therefore, in the embodiment of the present invention, the protruding corner line l-
l' (Figs. 1 and 4), the protruding corner roof blocks 1 are butted against each other so that their chevron-shaped fold lines coincide, and flat roof blocks 2 are placed on each side of each protruding corner roof block 1. The joint material 3 is used for joining to form a protruding corner roof.

Specifically, when the roof inclination angle is θ°, the projected planar shape is considered to be a square, and as shown in FIG. A pair of right-angled triangular plates whose crotch length is N/cos θ are joined together with their chord sides in such a way that each hook side is kept horizontal and the crotch side is inclined upward by θ° with respect to each hook side. It is a chevron-shaped block with a diagonal of the joint as a fold line, and the hook sides of both triangular plates (lower sides located at the bottom of the chevron block) are provided with a square-shaped fitting protrusion extending in the extending direction of the hook sides. 11,1
