DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior having a prefabricated roof, and more particularly to a structure for mounting a brace for supporting a roof and a column for supporting the boom.

[0002]

2. Description of the Related Art Exteriors having a prefabricated roof include a shelter, a porch, an entrance hood, an assembly sunshade also called a corridor, an assembly sunshade at a park or a stop,
Alternatively, there is a bicycle storage area, sun protection for carports and a terrace. As shown in FIG. 22, such an assembled roof 60 includes a girder 54, a purlin 53, a sunshade panel 52, and a rafter 51.
In order to fix the roof 60 to the hollow, a brace 56 and a support 55 are used. That is, the roof 60
Is supported by the arm 56 to which the load is stretched, and the support 60 supports the arm 56 to hold the roof 60 at a predetermined position.

[0003] Conventionally, such a prefabricated roof has adopted a stable structure in which a boom is supported by a plurality of columns.
In recent years, the degree of freedom in design has increased along with the improvement in the strength of the materials used, and in order to secure free space at the bottom of the roof and reduce the number of columns for the purpose of improving the overall appearance,
Prefabricated awnings in the form of a single point support for the crosspiece have been produced.

[0004] As a method of connecting such a one-point support type of arm and a post, a method shown in FIG. 23 has been used. That is, a notch (not shown) is provided at the upper end of the support 55, the arm 56 is fitted therein, fastened with bolts 61, and a brace 70 as a reinforcing material to reduce the momentum force acting on the connecting portion 64. 70 is used for reinforcement. The brace 70, 70 is obliquely inserted between the arm 56 and the support 55, and both ends are fastened with bolts 61, washers 62, and nuts 63, respectively.
The momentum generated in the arms 56 is shared.

[0005] Also, unless limited to the one-point support type,
As a general method of strengthening the connecting portion 64 between the arm 56 and the support 55, there is one disclosed in Japanese Utility Model Laid-Open No. 60-87909. In this case, as shown in FIG. 24, the arm bar 56 is further fixed to a notch 72 provided at the upper end of the support column 55 by using a U-shaped support bracket 78 having a vertical cross-section facing upward.
At this time, a plurality of protruding pieces 73 are provided on the support fitting 78 according to the width of the arm 56, and the arm 56 is fitted into the space defined by the protruding side 73, and the hole 75 of the support 55 Bolts 6 through holes 75 "in
1. A structure in which the washer 62 and 62 'are fastened by a nut 63 is adopted. Therefore, the arm 56 supported only by the side of the notch 72 is supported by the lower surface of the support bracket 78 and the plurality of projecting pieces 73, and more support points and support areas are obtained, so that the support is strong. The connection is obtained.

[0006]

As described above, in the prior art, the connection structure between the arm and the pillar has been locally strengthened, but in such a technology, a single-point support type is used. In such a case, the strength was insufficient to support a brace with a large moment, and in the present situation, it was necessary to resort to the method using a cane.

[0007] However, since this brace is provided so as to protrude between the arm and the support, it has been an obstacle for the awning user or passer-by when using it, such as hitting his head or catching a passing object. . That is, there is a problem that the original purpose of the single-point support type connection structure, which secures free space under the sunshade roof and makes the overall design simple and good, does not match.

[0008] Accordingly, the present invention has been made in view of the above-mentioned problems in the conventional connection structure between the arm bar and the support of the prefabricated sunshade, and has an object to secure a free space under the sunshade roof. The purpose is to ensure the convenience and safety of users and to make the overall design simple and good.

[0009]

SUMMARY OF THE INVENTION The present inventor has proposed that in the conventional connection structure between a brace and a post, the momentum generated in the brace is supported only by the frictional force of the bolt of the connecting portion or the frictional force of the side about the width of the support. Focusing on the fact that the need for assistance with a brace eventually arises because of the fact that it has been done, we studied diligently how to support the momentum generated in the arm tree without overhanging the problem brace. The present invention has been achieved as a result of aiming at a good design.

[0010] That is, according to the connecting structure of a brace and a support of the present invention, in order to solve the above-mentioned problems, a brace reinforcement, a brace receiver having an upward U-shaped cross section and extending in the length direction of the brace, and a brace receiver are provided. And a brace for supporting the brace and fixing the brace to the support, and a brace fitted to the brace reinforcement, and supporting the brace reinforcement and / or the brace with the brace support fixed to the brace support at the upper end of the support. It is characterized by.

According to the connecting structure of the arm and the support of the present invention, the arm reinforcement is fixed to the arm support, and the arm is fitted and fixed to the end thereof.
It is preferable that a shaping plate, which is flush with the outer surface of the crosspiece, be stretched over the non-contact surface of the crosspiece and the crosspiece with respect to the crosspiece.

According to the connecting structure of a brace and a pillar of the present invention, it is preferable that the brace reinforcement is fixed to the brace receiver, and the brace is fitted to both the brace reinforcement and the brace receiver. It is more preferable that a shaping plate, which is flush with the outer surface of the brace receiving portion, be stretched over a portion of the reinforcing surface that is fitted to the brace.

According to the connecting structure of the brace and the support of the present invention, the brace reinforcement is fixed to the brace support, and the brace fits into the brace reinforcement and simultaneously covers the brace support and the brace support support. In this case, it is preferable that the contact surfaces of the left and right arms are covered with an arm cover.

Further, according to the connecting structure of the crosspiece and the support of the present invention, the crosspiece reinforcement is concealed inside the left and right crosspieces, integrated and fitted into the crosspiece support. It is preferable to penetrate the buckle support and the buckle support support and fix it with one bolt.

[0015]

Therefore, according to the present invention, the arm bar reinforcement is fitted to the arm bar receiver having an upward U-shaped cross section fixed to the upper end of the support by the arm bar receiving support, and is received and supported by the inner surface of the lower end of the arm bar receiver. After that, these are integrated, and then the arm is provided so as to cover a part or all of the integrated arm reinforcement, arm support, and arm support support portion. Alternatively, the arms are fitted and integrated so as to conceal the arm reinforcements inside, then fitted to the arm receiver, received at the lower end of the arm receiver, supported and fixed, and integrated.

[0016] As a result, the momentum generated in the arm is eventually held by the arm receiver which extends in the arm direction, so that the support by the brace becomes unnecessary. In addition, arm support, arm reinforcement,
By arranging a shaping plate in addition to the crosspieces, it forms a smooth connecting surface with less unevenness, so it is also excellent in design,
The structure has excellent corrosion resistance because rainwater does not easily enter the interior.
