Description

  The present invention relates to a roof structure in which a roof body is suspended and supported via a hanging tool under a beam between columns.

  In general, the carport installed in the garage has a roof body on the front beam installed on the upper part of the left and right columns and the rear beam installed on the left and right columns installed on the rear of both columns. However, in the method of supporting the roof body on the beam, as shown in Patent Literature 1, the roof body is supported on the upper part of the beam and the roof body is suspended below the beam. It is considered to be a supporting method.

  In the system in which the roof body is suspended and supported under the beam, both sides of the roof body are suspended and supported by the beam via suspension members.

  By the way, recently, the concept of the roof structure is based on a common viewpoint that the roof protects people and cars from wind and rain, etc., and a large roof structure that simply consists of a carport, a terrace roof, and a front door in the entrance approach. The momentum toward the realization of is increasing. According to such a large roof structure, a comfortable interior extension space can be created on the outdoor side.

  For example, considering the case of increasing the size of a conventional carport-type structure, as shown in Patent Document 1, the roof has an arch shape. Since the arch shape naturally flows along the inclined surface, rainwater flows easily, and it is easy to finish rain, and the shape that bends upward in a bow shape was a novel design when it first appeared on the market, so it is widespread doing.

  However, in order to make the entire roof body into an arch shape, it is necessary to curve a metal rafter, a roof panel, and the like that are laid between the frame material and the opposed frame material constituting the roof body. In order to stably hold the roof panel formed in the arch shape on the support material, as shown in Patent Document 1, the vertical material and the horizontal material of the cross beam and the field edge are crossed, and the roof is formed thereon. A configuration was adopted in which the panel was supported and the roof panel was pressed down with a presser.

Further, the screw 31 is fastened to the groove wall 23 on the second opening edge 21 side, and the tip end side thereof is engaged with the engagement hole 9 formed in the second engagement piece 26 of the hanging tool 10 for positioning. . In the same manner, a plurality of hanging tools 10 are attached to the lower part of the beam 3 at a predetermined interval.

  Next, a rafter 15 of the roof body A is attached to the lower part of the hanging tool 10. The rafter 15 is a member erected on the front frame 11 and the rear frame 12 of the roof frame 14, and as shown in FIGS. 5 and 6, in the upper center of the elongated straight plate-like body 15 a, its longitudinal direction A hollow rising portion 22 is formed so as to project upward, and a support portion 46 of the roof panel 16 is formed on both sides of the rising portion 22 so that the upper end of the rising portion 22 bulges, and the upper end surface of the head portion 22a. Inclined guide surfaces 22b are formed on both sides. In addition, an engaging groove 32 that opens downward is formed at both lower portions of the head portion 22a, and a screw receiving groove 33 is formed obliquely downward from the outside to the inside thereof.

  Two fitting ridges 34 and 35 are formed in parallel on the outer side and the inner side of the upper surface of the support portion 46 along the longitudinal direction, respectively. The first beat 37 is fitted to the fitting ridge 35. A second beat 36 is fitted and fixed to the mating ridge 34. The first beat 37 and the second beat 36 have the same height. Further, a bolt insertion hole 39 is formed through the rising portion 22 so as to correspond to the arrangement of the hanging tool 10. The length of the rafter 15 is longer than the distance between the front and rear beams.

  When the rafter 15 is fixed to the lower part of the hanging tool 10, the rafter 15 is disposed below the front and rear beams 3, the rafter 15 is pushed up from a position below the hanging tool 10 fixed to the beam 3, and the rising portion 22 of the rafter 15 is The two guide surfaces 22b are engaged with the ends of the two suspension pieces 17 and 17 of the hanging tool 10 and pushed further strongly. The suspension piece 17 is restored after being elastically deformed outward along the guide surface 22 b, and the engagement claw 27 of the suspension piece 17 is elastically engaged with the engagement groove 32 of the rising portion 22. Further, as shown in FIGS. 6A and 6B, a tubular spacer 38 is fitted from the bolt hole 28 of the hanging piece 17 to the bolt insertion hole 39 of the rising portion 22, and the fixing bolt 40 is set inside the spacer 38. Is inserted and fixed with a nut 41 through packing or the like. In this way, the corresponding rafters 15 are fixed to the hanging tools 10 of the front and rear beams 3, respectively. Since the suspension pieces 17 and 17 are regulated at a constant interval by the spacer 38, it is possible to effectively prevent the suspension pieces 17 and 17 from being deformed by excessively tightening the fixing bolt 40 and the rising portion 22 from being crushed. Can do.

  Further, a front frame 11 and a rear frame 12 are fixed to the front and rear ends of each rafter 15, and side frames 13 are fixed to both ends of the front and rear frames 11 and 12. The side frame 13 is attached integrally with the rafters 15 at both ends.

  Next, as shown in FIG. 5, the roof panel 16 is sandwiched and fixed from above and below by the rafter 15 and the panel presser 42.

  The roof panel 16 is composed of an elongated flat plate made of translucent synthetic resin such as acrylic or polycarbonate. The side edges of the roof panel 16 are supported on the two beats 36 and 37 of the both side support portions 46 of the rafter 15. The upper part of the side edge of the roof panel 16 disposed between the adjacent rafters 15 and 15 is pressed by a panel presser 42.

  The panel presser 42 is a long metal plate-like member in which one side 42 a is bent obliquely and the other side 42 b is formed with a fitting protrusion 44 of the upper beat 43, and is arranged along the entire length of the rafter 15. ing. The bent portion 42 a is in contact with the opening edge of the screw receiving groove 33 of the rising portion 22 of the rafter 15 and is fixed by a screw 45 screwed into the screw receiving groove 33 obliquely downward. At this time, the upper beat 43 and the first beat 37 are provided at positions corresponding to the upper and lower sides, and are arranged so as to sandwich the end portion of the roof panel 16. The second beat 36 is disposed on the center side of the end portion of the roof panel 16. When the screw 45 is screwed into the screw receiving groove 33, the upper beat 43 of the panel retainer 42 is strongly pressed against the upper surface of the roof panel 16 as the screw 45 is screwed. Then, both side edges of the roof panel 16 are elastically pressed and firmly fixed between the inner and outer beats 37 and 36 of the adjacent rafters 15 and the upper beat 43 of the panel presser 42. The front and rear end portions of the roof panel 16 are supported by the front frame 11 and the rear frame 12, respectively.

  A rafter connecting member 7 (see FIG. 1) is disposed in the center of the roof body A in the left-right direction, and is fixed to each rafter 15 with screws.

  As described above, both side edges of the roof panel are placed on top of the first beat 37 and the second beat 36 of the support portion 46 of the adjacent rafter 15, and the top of the side edge of the roof panel 16 is the first beat 37. Are pressed and fixed by the upper beat 43 of the panel presser 42 arranged so as to correspond to the above. Therefore, even if the center portion of the roof panel 16 is bent downward due to its own weight or the like, the end portion of the roof panel 15 is caused by the pressing force from above and below by the second beat 36 of the rafter 15 and the upper beat 43 of the panel presser 42. Since the roof panel 15 is held horizontally, the deformation of the roof panel 15 is suppressed, and the roof panel 15 is always fixed in a state of maintaining the horizontal state. In this way, the roof panel 16 is supported and fixed in triplicate by the inner and outer beats 37 and 36 and the upper beat 43, so that the roof panel is prevented from being bent and twisted and can be reliably supported. The durability of can also be improved.

  Moreover, since the above-mentioned roof structure formed the front and rear frames 11 and 12 of the roof body A and the plurality of rafters 15 spanned in parallel to these front and rear frames, respectively, the roof body A is made flat. In addition, the roof panel 16 can be securely attached to the rafter 15 of the roof body by a minimum number of components such as the rafter 15 and the panel retainer 42 without providing a roof panel support member such as the center of a conventional carport. Since it can be installed, a simple roof structure is obtained. Furthermore, since the area which covers the ground and protects it from rain is substantially the same as the surface area of the entire roof, the ground can be efficiently covered. Therefore, the total weight of the roof A is reduced compared to the arch-shaped one, and considering the area covering the ground, the load load on the beam 3 does not increase so much. For example, it covers the garage, the entrance, and the terrace. A large roof structure can be realized, and the roof structure can be used for various purposes.

  In addition, the roof A is flat and only a plurality of rafters 15 appear in parallel on the inside, and the upper part of the beam 3 and the pillar 2 is inconspicuous, so even if the structure is enlarged, it is simple. It is an elegant design, and it is possible to create an interior space that is cozy, comfortable, and comfortable, and extends to the outside.

  Furthermore, since the front and back surfaces of the roof panel 16 are in close contact with the upper and lower beats 43 and 37, rainwater that has fallen on the roof panel 16 does not enter the back side due to the sealing effect, and rain dripping does not occur.

  Furthermore, since the upper beat 43 and the first beat 37 are provided at positions corresponding to the upper and lower sides, the roof panel can be sandwiched and pressed most efficiently.

  In addition, the roof panel 16 is only sandwiched and fixed by the support portion 46 of the rafter 15 and the panel presser 42 and does not use a screw exposed downward, so that the internal appearance is not impaired by the screw head.

  Since the panel retainer 42 can be easily removed by loosening the screw 45 of the screw receiving groove 33, maintenance and replacement work for the roof panel 16 can be easily performed.

  The number of beats is at least one at the top and two at the bottom, but is not limited to this. There may be two or more at the top and three or more at the bottom. The upper and lower beats are not necessarily arranged at corresponding positions.

  Furthermore, the roof body does not necessarily have a suspended structure. The structure which supports a roof body on a beam may be sufficient.
