Description

[Technical field]

[0001] This invention relates to a simple roof structure primarily for use in bicycle parking areas. [Background technology]

[0002] Simple roof structures used in bicycle parking areas, etc., have beams formed at the tops of several posts that are appropriately erected on a base, and roof panels are either placed directly on the beams, or a main building is erected between the beams and roof panels are placed on the main building.

[0003] The connecting structure between the pillar and the beam needs to be appropriately robust, and for example, Patent Document 1 discloses a connecting member that is composed of a pair of clamping pieces that clamp a cylindrical pillar and that is extended outwardly to provide a beam connecting portion. Patent Document 2 discloses a connecting member that is provided with a connecting portion that opens outward above a pillar mounting portion that is capped on the top of the cylindrical pillar and that connects a beam to the beam by placing it on the connecting portion. Patent Document 3 discloses a connecting member made of a T-shaped metal fitting that has a connecting portion that connects to the cylindrical pillar at the bottom and a beam connecting portion at the top.

[0004] [Patent Document 1] Utility Model Registration No. 2583379. [Patent Document 2] Patent No. 6188064. [Patent Document 3] JP 2019-65589 A. Summary of the Invention [Problem to be solved by the invention]

[0005] In constructing a simple roof structure, the specified connecting members disclosed in the above patent documents are used to connect the pillars and beams, but the connecting members in patent documents 1 and 2 are structurally complex and their manufacture is troublesome. Also, the connecting member described in patent document 2 is fitted over the top of the cylindrical pillar, so the connecting position can be specified and there is no problem with workability, but the connecting members in patent documents 1 and 3, which are made up of a pair of members, require the work of inserting connecting bolts or the like while aligning and holding the members at the specified connecting position on the top of the cylindrical pillar, making the installation work very troublesome.

[0006] Therefore, this invention proposes a simplified roof structure that uses a pillar and beam connecting structure that is simple in structure and easy to work with. [Means for solving the problem]

[0007] The simple roof structure according to claim 1 of the present invention is a simple roof structure in which beams are formed at the tops of a number of pillars erected on a foundation, and roof panels are either placed directly on the beams or a purlin is erected between the beams and roof panels are placed on the purlins, in which the connecting structure between the pillars and the beams is characterized in that the upper ends of the pillars are provided with a groove of an appropriate depth corresponding to the beam direction, and an insertion hole that is continuous with the groove and a connecting hole that passes through the insertion hole in a direction perpendicular to the beam direction, and at the pillar connecting position on the beams, a fitting plate portion that fits into the groove, and an insertion plate portion is formed below that is continuous with the fitting plate portion and a through hole that corresponds to the connecting hole portion, and the insertion plate portion of the beam is inserted from the upper end of the pillar, and the fitting plate portion is fitted into the groove, and a connecting shaft body that passes through the connecting hole and the through hole is attached.

[0008] The top of the support has a simple structure consisting of a groove and an insertion hole, and it is only necessary to provide the beam with the required plate parts (fitting plate part and insertion plate part).By aligning the plate parts with the insertion hole and groove part, the connection points can be easily positioned, making the work easier.By matching or approximating the dimensions of the connection points, wobble in the longitudinal and torsional directions of the beam can be prevented.

[0009] In addition, in the simple roof structure according to claim 2 of the present invention, the support pillar is particularly formed from a tubular body, and it is only necessary to form a groove portion on the upper edge of the support pillar (tubular body), and the formation of an insertion hole can be omitted.

[0010] In addition, the simple roof structure according to claim 3 of the present invention has roof panels made of solar panels, making it possible to illuminate the surrounding area without the need for an external power source, especially when the simple roof structure is used for a bicycle parking lot.

[0011] In addition, the simplified roof structure according to claim 4 of the present invention is constructed by placing and fitting a purlin with a U-shaped cross section with one open side into a recess formed on the upper surface of a beam, and connecting the purlin to the beam by protruding a U-shaped bolt that is placed across the underside of the beam from the underside of the purlin and screwing a nut into place. This makes it easy to form a purlin with a smooth upper surface, and makes it easy to install solar panels on the purlin. Effect of the Invention

[0012] The configuration of this device is as described above, and when constructing a simple roof structure, the plate portion attached to the beam is inserted and fitted into the top of the support, making it easy to position the connecting shaft body for penetrating and attaching it, thereby improving the work efficiency of constructing the simple roof structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Next, an embodiment of the present invention will be described. The simple roof structure shown in the embodiment has beams 3 formed on the tops of multiple pillars 2 supported and erected on a foundation 1 constructed of concrete, a main building 4 erected between the beams 3 arranged in parallel, and roof panels (solar panels) 5 provided on the main building 4.

[0015] The present invention is particularly characterized by the connection structure between the support columns 2 and the beams 3 and the connection structure between the beams 3 and the purlins 4. Next, the connection structure between the support columns 2 and the beams 3 will be described.

[0016] A groove 21 of an appropriate depth corresponding to the construction direction of the beam 3 is formed at the upper end of the support (tube) 2, and a connecting hole 22 is provided at a position appropriately below the groove 21 in a direction perpendicular to the construction direction.

[0017] A plate portion 31 is installed on the beam 3 at the connection position between the beam 3 and the pillar 2. The upper portion of the plate portion 31 is an engagement plate portion 32 that engages with the groove portion 21, and the lower portion continuing from the engagement plate portion 32 is an insertion plate portion 33, and a through hole 34 corresponding to the connecting hole portion 22 is provided. In particular, the thickness of the engagement plate portion 32 is made to match the width of the groove portion 21, and the width of the insertion plate portion 33 is made to match the inner diameter of the pillar 2.

[0018] The work of connecting the pillar 2 and the beam 3 is carried out by inserting the plate portion 31 of the beam 3 inward (the hollow portion of the tube body: insertion hole) from the upper opening of the pillar 2, and then placing and fitting the mating plate portion 32 into the groove portion 21 so that it is attached without any rattling. The positions of the connecting hole portion 22 and the through hole 34 match up, allowing the connecting shaft body (through bolt) 6 to be easily passed through. When the nut 7 is screwed and tightened onto the connecting shaft body 6, the pillar 2 and the beam 3 are firmly connected.

[0019] Next, the connection structure between the beam 3 and the purlin 4 will be described. At the mounting position of the beam 3 to the purlin 4, a recess 35 corresponding to the shape of the purlin 4 to be attached is formed on the top surface of the beam 3. The purlin 4 is a long material with a U-shaped cross section with one side open, and connection holes 42 are formed on the underside 41 of the purlin 4 at both outside positions of the beam 3 when it is placed and fitted into the recess 35 of the beam 3.

[0020] The main structure 4 is then placed and fitted into the recess 35 of the beam 3, the tip of the U-shaped bolt 8 spanning the underside of the beam 3 is inserted into the connecting hole 42, and the nut 7a is screwed and tightened onto the part protruding from the underside 41 of the main structure 4 to fix the main structure 4 to the beam 3.

[0021] The present invention is not limited to the above embodiment, and in particular, the support 3 may not be a tube, but may have a predetermined groove and insertion hole formed at the upper end. [Explanation of symbols]
