Description

[Detailed description of the invention] This invention relates to a prefabricated rain protection structure suitable for configuring garages, bicycle storage areas, terraces, passageways, etc., and its purpose is to save labor in assembly work on sloped areas. It is in.

To specifically explain an example of the proposed structure using a drawing, vertical columns 1, 1, 1, 1 are erected in a rectangular position, and a girder 2 is horizontally suspended at the top of the columns 1, 1 in the left and right direction. However, when applying the roofing material 3 to the upper part of the girders 2, 2 at the front and rear positions, the pillars 1, 1 having different heights at the left and right positions are provided as a set in the front and rear, and a bearing part 9 with an arcuate concave surface formed on the upper inner side. A strut joint member 6 having a U-shaped cross section mounting piece 4 on the lower side,
It is fixed to the top of each pillar 1 as a pair in the front and back, and the girder 2
Girder joint members 8, 8 each having stepped portions 10, 10 placed downwardly on the lower left and right sides to form an engaging protrusion 7 with an arcuate convex surface are fixed to the upper end of the bearing portion 9 of the column joint member 6 in a horizontal state. Step portion 10 of engagement protrusion 7,
10, the bearing portion 9 of the column joint member 6 and the engagement protrusion 7 of the spar joint member 8 are fitted, and the bearing portion 9 of the column joint member 6, 6 is fitted in an arc shape. The pin shaft 12 is connected to the boss 14 formed concentrically with the concave surface and the boss 5 formed concentrically with the arcuate convex surface on the engagement protrusion 7 of the spar joint member 8, so that the spar 2 is connected to the support 1.
, and the pin shaft 12 is screwed to fix both joint members integrally.

In carrying out the present invention, the strut may be made by aluminum molding, a vertical groove having a locking edge may be provided, and the strut joint member may be screwed into this while adjusting the vertical position.

In the figure, 13 indicates a rain gutter.

Since the present invention has the above-mentioned configuration, when the column 1 is erected and the girder 2 is horizontally mounted on it, a pair of column joint members 6, 6 having an arcuate concave bearing portion 9 at the top of the column 1 are used. is attached, and a spar joint member 8 having an arcuate convex engaging protrusion 7 formed on the bottom surface of the spar 2 is fixed, and one of the engaging protrusions 7 of the spar joint member 8 is connected to the strut joint member 6 of one strut 1. , 6 and temporarily fasten the other girder joint member 8 of the girder 2 to the other support column 1.
The work of fitting the girder 2 into the strut joint members 6, 6 and temporarily installing the girder 2 can be carried out on the ground or in a position close to the ground. When the engaging projections 7 of the members 8 are to be engaged concentrically, the arcuate bearing portions 9 of the strut joint members 6, 6 and the arcuate engaging projections 7 of the spar joint member 8 are engaged with each other, and Although the girder 2 rotates in the vertical direction until the upper ends of the bearings 9 and 9 come into contact with the stepped portion 10 of the engagement protrusion 7, further movement is restricted, so the girder 2 may become detached from the support column 1 or become large. There is no risk of tilting, and the engagement protrusion 7 of the girder joint member 8 can move upward or downward depending on the inclination angle of the installation surface due to its own weight relative to the bearing parts 9, 9 of the column joint members 6, 6. Since it rotates, the pin shaft 1 can be easily aligned by aligning both joint members in a concentric position.
2 can be inserted.

Further, according to the present invention, the pin shaft 12 is inserted between the bearing parts 9, 9 of the column joint members 6, 6 and the engagement protrusion 7 of the spar joint member 8, and the pin shaft 12 is screwed until both joint members are integrated. Since it is fastened, the practical effects are remarkable, such as the bond strength being high and durability being high.
