Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a curved frame that forms equal curved angles (cuffs), and its purpose is to
We provide a curved framework for constructing effective frameworks by improving productivity and economy by making effective use of the internal space of the drug and unifying the types of curved parts of the framework structure, which has a complex external shape. In addition, it is useful in the field of co-located props when multiple props of the same standard are installed together with a distance of 1η or less, such as hanging type mole rails, outdoor cranes, tunnels, bridges, garden frames, etc. The purpose of the present invention is to provide a curved frame plan for forming curved corners.

In order to achieve the above-mentioned object, the present invention has been made by connecting the points obtained by dividing the arcs of two quarter circles into equal parts by a suitable number. ,
Or the intersection of the extension line of the -ka fold line and the other fold line? According to the bending analysis published by the skeleton department, the inscribed angle between the broken lines and the intersection angle between the above extended line or the above extended line are equal to the bending angle θ
It is a curved frame in which the bending line and the extension line are separated from the frame part, and the whole or part of this curved frame is directly or indirectly installed on the foundation, and is further horizontally By attaching roofing materials, wall materials, window coverings, etc. to all or part of the structure, the interior space described above can be used effectively, and structures with complex external shapes can be constructed without bending of the frame structure. By unifying the types of parts, it is possible to obtain a frame structure with excellent productivity and economic efficiency, and it can also be used for suspension-tobage type molar rails, civil engineering, mining supports, etc.

In the past, many shapes have been devised for the roofs of buildings, and many buildings have been constructed based on them.
In Group II of roof structural members, the joint angles of the frame members are limited to right angles or polygons inscribed or circumscribed in a circle. In general, frames based on polygonal joint angles have strong resistance to external forces and are mechanically superior, but structures that are inscribed and inscribed in a circle have a simple shape and are aesthetically problematic, and are difficult to use. There is a lot of wasted internal space, and if you try to create a complicated shape that is separate from the inner and outer parts of the circle mentioned above, or try to reduce the wasted internal space, the joint angles of the frame materials will have to be of many types when designing and constructing. This led to troublesome drawbacks. This is especially a problem in large roof structures that use complicated member cross-sections or in roof structures that are mass-produced. According to the present invention, it is possible to construct frames of many types of shapes using a curved frame formed by a single curved angle, and to construct a structure that is both highly productive and economical and can meet high aesthetic requirements. The structure and operation of the present invention will be explained with reference to the drawings. It goes without saying that the framework that has this invention belongs to the technical scope of the present invention (even if its embodiments are different from those described in this specification).

First, the basic principle of the curved frame forming equal curved angles according to the present invention will be explained by drawing a diagram. In FIG. 1, A and B are two points set apart by an appropriate distance, and it does not matter whether the A and B points are on the same horizontal line or not.

Further, the two points A and B may overlap at the same location.

r-1 and r-2 are radii AE and BG of arbitrary scale on the horizontal line including the above two points A and B, respectively, facing in opposite directions to the outside directions P and Q. Figure 2a

N is the equal dividing line of arcs G-1 and C-2 (Fig. 2 a, b
(Let's draw it as a bisector), D is equal to the quarter line N and -・
The intersection of arcs C-1 and C-2, I-1 and ■-2 are two broken lines connecting points E, D, and F of quarter arc C71,
J-1 and J-2 are two broken lines connecting points G, D, and H of quarter arc C-2, and L and M extend the same ends of broken lines knee 2 and J-2, respectively. is the extension line, K is the extension line, M or the intersection of one extension line and the other broken line, I! i+ is the broken line I-1, ■-2 and the broken line J-1,
, J 2 and the extension line, M'''i!, are the intersection angles of one extension line and the other broken line. In Figure 2 a, the extension line intersects the extension line M, In , the extension line intersects the broken line J ・-2. Fig. 2 c, d
(In the case of three equal parts), one intersection point in Figure 2 a and b becomes two points D-1 and D-2, and two broken lines I-1, I-2 and J-1, J-2 is I-1, I
・-2, I-3 and J-1, J-2゜J-3 are the same except that the intersection angles θ are the same in Figure 2 a to d. +1 light/ζ. Then, say this.'' When IJ is a bisector as shown in Figure 2 (hereinafter, let the equal fraction be n, and if it divides into thirds, then ■1-

), it was found that θ=165°. From the above, if the number of equal divisions gN is the same, that is, if the equal number n is the same, the intersection angles of extension lines or broken lines and extension lines are the same everywhere, so this result can be expressed as When used to form a frame structure that supports a structure such as a skeleton, the bending angles of the frame 1 are formed with equal bending angles.When constructing a beak assembly with a complicated shape like the above-mentioned ξ, many types of bending angles are required. , it took a lot of time and money to process and construct the curved parts of the 1ili material, but the shape of the curved parts can be made into a single shape, and the role of the frame, manufacturing,
It is possible to produce dramatic productivity and economic effects in all fields of construction, and it can also fully meet architectural aesthetic requirements. That is, the present invention is based on the above-mentioned basic principle, and the gist of the present invention is to form a framework using figures created by giving the following five variables.

There are various types of concrete structures for the bent structure, such as joining, welding, and bending. A is an example of joining using high-strength bolts, and ■ and 2 are H to be joined, respectively.
Type steel materials, 3 and 4 are connecting plates welded to the ends of H type steel, 5
6 is a concrete foundation, and 6 is a high-pitched bolt for fixing the connecting plate by bolt holes drilled in the required openings of the connecting plate] and a fastening nut. In this case, U and ■, v and X1X and Y
The bending angle (cuff) of each joint is the same in this example, so the cutting angle at the end of Type II steel is the same.C
The specifications at the station are simplified. Is the H-shaped steel in Figure 7 different from Figure 7a? In the example of the joint using plates, 2 and 2 are the same H-type steel materials as in Figure 7a, and 6 is a concrete foundation. 7 is I (an end plate fixed by welding or the like to the joint end of the shaped steel plate, with a bolt insertion hole 12 for joining. 8 is a patch plate with a bent part reinforced by 9 parts of reinforcing lip, and 1o is a rectangular flat plate. Insertion holes 12 B are provided in both backing plates in the holding plate, 11 is a reinforcing rib, and 5 is a bolt nut for fastening. Figure 7 C shows a case where an inverted V-shaped folded plate is used as a frame part. Peel 1 cut at an angle determined by
(2) Connecting flanges 18, 18 are installed and fixed to the folding plate by welding or the like, and the flanges 18 are connected to each other by high-strength bolts and nuts 5.

Next, an example of a structure using the curved frame of the present invention will be explained. In FIG. 8, 0 indicates the curved bone KJ1 formed with the same bending angle of the present invention, and the number of months is the above-mentioned) ■ type steel side;
In addition to inverted V-shaped folding plates, ■ shaped steel strips, square steel pipes, round steel pipes,
Types such as truss beam columns, control beams, and beams 42 are used, but these are connected by connecting plates, backing plates, or flanges for G connections to form curved corners of a predetermined angle. In the case of the moon, the same span S was created by joining parts by welding or bending, or by deforming the material of the book.

Reference numeral 4- represents a connecting member that horizontally connects each of the facing frames 13, 13, . . . , and 15 represents a place. In the case shown in FIG. 8 6', the curved frame has the structure shown in FIG. 8 1, so θ=135° and n22.

If, for example, the part marked ■ in Figure 8 is to be used as a roof for the above-mentioned frame, the roof can be made by connecting known V-shaped roof slabs, inverted V-shaped roof slabs, etc. as shown in Figure 9 a and b. to make it rough, etc. In Figure 9 a and b, 16 is a ■ shape or an inverted v, respectively.
A long folded plate of the shape 17 is a long connecting material-C that continuously connects the long plate plates IG in parallel. In Fig. 8, ■ is used as a window for example, but the part with the break may also be used as a wall. (2) is a wall part connected to the foundation 6 of Core Creation 1 or a space without a wall. As a result of the above, a roof structure with no pillars between the spans S can be created. Figure 1O is the inverted V-shaped roof plate 1 of Figure 9.
What if the entire outer surface of the frame shown in Figure 8 is roofed using No. 6? As an example, even when using a member with a complex cross-sectional shape of 4φn, a structure with a unique design can be standardized by adopting a curved part with a single curved corner (cuff) that is incomparable to the conventional one. This can be easily implemented by using technical means to overcome the conventional situation where a large amount of time and money was spent on the iiQ tf and manufacturing of bent portions. Fig. 11a shows a plan view of a curved frame row arranged in a rectangular arrangement, Figs. This is a plan drawing.

As explained above in detail, the present invention is a frame formed by curved angles with equal angles, so the +=
- Or multiple parallel planes of different spans can be moved parallel to each other in parallel to a rectangular plane as shown in Figure 11, or a zigzag plane as shown in Figure 11, and several as shown in Figure 11C. For example, 1 r.

Each of the groups n' and Ill' has curved frames with different spans, and the rows of frames that move together are connected by connecting members (not shown), and then appropriate roofs, wall materials, and window materials are provided as necessary. It can be constructed as a frame structure without any additional construction, and by combining these structures with the selection of roofing materials, wall materials, etc., structures with complex shapes that could not be obtained in the past can be created under conditions with excellent productivity and economic efficiency. In addition, the space divided by these structures does not require pillars in most cases, so it is spacious and has enough space from the bottom to the ceiling, so it can be used simply as a structure for cultural or physical education purposes. In addition, it can also be used as a facility for covering large spaces such as industrial and commercial warehouses, aircraft hangars, outdoor theaters, outdoor sports facilities, etc. Furthermore, it can also be used as a support for the above-mentioned suspended mole rails, civil engineering, mines, etc. It can be said that the application is extremely wide in the field of industrial supports, so the effects brought about by the present invention are remarkable.
