Description

  The present invention relates to a roof such as a terrace roof or a carport roof.

  The main components of a terrace roof or a carport roof (hereinafter, typically referred to as a terrace roof) are a column that is erected on the ground, a roof frame that is attached to the upper end of the column, and a fixed frame to the roof frame. It can be broadly divided into roof panels. And, the roof frame is usually a front frame (frame inside the site) and a rear frame (frame outside the site), and rafters arranged between the front frame and the rear frame (arranged at both ends) Including wife rafters.) In addition, the rainwater drainage device provided on the terrace roof is allowed to flow from the end of the rear frame side of the roof plate to the rain gutter provided on the rear frame, and received by the drain connected to this from the drainage port of the rain gutter, Rainwater is drained to the ground by a vertical shaft attached to the column from the drain through an elbow.

The following is known as a connection structure of the roof frame to the column in the terrace roof.
1) A structure in which one end side of the rafter of the roof frame is fixed to the upper end portion of the column by a bracket and a bolt and nut. For example, Patent Document 1.
In this case, the roof frame is supported in a cantilevered manner with respect to the column, but one end of the rafter protrudes backward (in the direction away from the building) from the column, and is therefore connected to one end of the rafter. Since it is separated rearward from the support column, the rain gutter and drain provided on the frame are also provided at a position separated rearward from the support column.
2) A structure in which a girder is installed between the upper ends of the columns and the rafters of the roof frame are connected to the girder with bolts and nuts. For example, the specification of Japanese Patent Application No. 2005-95228 related to the proposal of the present applicant.
In this case, a fixed edge that abuts the bottom surface of the rafter is provided on the top surface of the girder, and the fixed edge is connected to the rafter by a bolt and nut, but by changing the position where the top surface of the girder abuts the bottom surface of the rafter, The separation distance from the support can be arbitrarily determined.

Then, the screw b3 is screwed into the fixing portion 52, and the other side of the connection fitting similar to the connection fitting 8 fixed in advance to the end of the rafter 5 is fixed to the rafter abutting wall 48 with a screw (not shown). As a result, all the rafters and the rear frame are connected. A front frame (not shown) is connected to the opposite end of each rafter by a known structure and method.

  The girder 3 is connected to the roof frame RF configured as described above as follows. That is, as shown in FIGS. 1 and 2, when the roof of the form in which the rear frame 4 protrudes backward from the support column 1 is small, the girder 3 is brought under the hollow portion 44 of the rear frame 4 and fixed. The edge 34 abuts on the girder connection wall 46 of the rear frame 4, and the screw b <b> 2 is screwed into the girder connection wall 46 from the fixed edge 34. In this case, the upper side of the girder connection wall 46 is a hollow portion formed between the rafter abutting wall 48 and the intermediate wall 410 of the hollow portion 44, and since there is no obstruction, the screw b2 can be easily screwed.

  The girder 3 connected to the rear frame 4 of the roof frame RF is attached to the upper end portion of the support column 1 that is not yet erected on the ground through the connector 2 as follows. That is, the shaft 25 of the bolt b in which the male fitting portion 32 of the girder 3 is mounted in the groove 37 of the girder 3 in the female fitting portion 23 of the coupler 2 is the long hole 25 of the rectangular curved plate 23a of the coupler 2. The nut n is lightly tightened to the shaft of the bolt b protruding from the rectangular curved plate. Subsequently, in this state, the support column is brought into a vertical state. In that case, since the male fitting part 32 and the female fitting part 23 are curved and can be turned around the center of the arc, the support column 1 can be easily brought into a vertical state. Then, by completely tightening the nut n, the rear frame 4, the girder 3 and the column 1 are connected, and the rear frame 4 only projects slightly from the back surface of the column 1.

  Therefore, the amount of protrusion of the drain 72 coupled to the bottom of the rain gutter 41 of the rear frame 4 from the back surface of the column is small, and the amount of protrusion can be suppressed to within 5 cm as an example. Therefore, as shown in FIG. 1, even when the column 1 is erected in close proximity to the eaves 9 installed with the thickness center aligned with the boundary line with the adjacent land, the rear frame 4, the drain 72. It is possible to install a drainage device such as a vertical rod 74 without projecting to the adjacent ground. Therefore, the effective area when installing a terrace roof or a carport roof on a narrow land can be expanded as compared with the case of using a conventional roof.

  As a preferred embodiment of the present invention, as described above, the girder connection wall 46 and the rafter connection wall 47 of the rear frame 4 exist on the same plane as the bottom surface of the rear frame 4, and the girder 3 is formed on the upper end surface thereof. In addition to being configured to fix the fixed edge 34 to the girder connection wall 46, there is a step equal to the thickness of the rafter connection wall 47 between the fixed edge 34 of the girder 3 and the rear of the upper end surface of the girder. It is provided. Therefore, as shown in FIGS. 3 and 4, the fixing edge 34 of the girder 3 is brought into contact with the bottom surface of the rafter 5, and the convex wall 33 at the rear end of the upper end surface of the girder 3 is connected to the bottom surface of the rear frame 4 or the girder connection wall 46 or rafter. The girder 3 can be connected to the rafter 5 in a stable state by abutting against the connection wall 47 and screwing the screw b2 into the rafter 5 from its fixed edge. Thereby, the support column 1 can be separated from the rear frame 4.

  Therefore, if there is room on the site, or if desired for the appearance, the same roof can be either a roof with a rear frame or drain that does not protrude backward from the column, or a roof with a protruding shape. be able to. Therefore, the effects of reducing manufacturing costs and reducing member management can be obtained.
