Description

Technical Field

[0001] The present invention relates to an independent structure for attachment to a building and a support structure for the independent structure for attachment to a building, which are constructed and installed by column support on the front surface of a building opening or wall surface, such as a terrace, a sunroom, a cycle port, etc.

Background Art

[0002] Buildings such as terraces and sunrooms constructed by column support on the front surface of a building opening or wall surface secure the fixing strength of the roof against the wind pressure and snow load by fixing the end of the roof body supported by the column to the body using fixing fittings such as screws and bolts. Patent Document 1 below provides a fixing to the body by providing a curved surface that is rotatable relative to each other on the connection frames on the body side and the roof side, so that the fixing to the body can be made according to the roof inclination angle even when the roof inclination angle is different in relation to the building installation space.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In this case, although the fixing strength of the roof against the wind pressure and snow load can be ensured as described above, by using fixing fittings such as screws and bolts for fixing to the body, it cannot be denied that rainwater may penetrate from the body fixing part and the rainproof finish of the wall surface may be impaired. Recently, due to the implementation of the Housing Defect Warranty Enforcement Act, housing manufacturers and housing construction contractors tend to avoid fixing to the body of buildings using fixing fittings such as screws and bolts that may affect the rainproof finish, while the client often desires the installation of a terrace, a sunroom, etc.

[0005] Therefore, when it becomes necessary to make these structures into independent structures attached to a building that are independently constructed by column support without being fixed to the building body on the front surface of the building opening or wall surface, it becomes necessary to effectively and aesthetically process the gap that occurs between the free end of the roof and the building body when the structure is made into an independent structure.

[0006] The present invention has been made in view of such circumstances, and the problem to be solved is to provide an independent structure attached to a building and a support structure for an independent structure attached to a building that can effectively and aesthetically process the gap that occurs between the free end of the roof of the independent structure and the building body.

Means for Solving the Problem

[0007] The independent structure attached to a building of the present invention includes a roof, a closing member that protrudes from the roof toward the building body, and a mounting frame. A portion on the proximal end side of the closing member is screwed and fixed to the mounting frame. The roof includes an end frame provided at the end on the building body side. The mounting frame is fixed above the end frame. The end frame includes an extending piece that extends upward at the end on the building body side. After the extending piece extends upward at the end on the building body side of the end frame, it bends and extends toward the side opposite to the building body.

Effect of the Invention

[0008] Since the present invention is configured as described above, for example, the installation of an independent structure with a roof supported by columns such as a carport or a cycle port is a building annex type in which a swinging deflection gap at the free end of the roof is arranged between the free end of the roof and the body and constructed. The swinging deflection gap actively allows the swinging of the free end of the roof in a non-contact state with the body. Due to the load of the wind pressure and the snow load, the free end of the roof swings in the vertical direction, eliminating the possibility that the free end of the roof contacts the wall surface of the body and damages the wall surface of the free end of the roof or the body. On the other hand, a closing member is arranged in the swinging deflection gap between the free end of the roof and the body so as to prevent the intrusion of rainwater as much as possible, and the closing member is made of a highly elastic stretchable material. By elastically pressing the tongue-shaped tip arranged on the closing member against the body so as to be slidable in the vertical direction with respect to the body, it is possible to provide an independent structure for building annexes that can effectively and aesthetically process the swinging deflection gap with long-term durability.

Embodiments for Carrying Out the Invention

[0010] The present invention will be described in more detail with reference to the following drawings. In FIGS. 1 to 5, reference numeral 1 denotes an independent structure for attachment to a building, which is constructed independently by means of column support without being fixed to the front surface of a building opening or wall surface. In this example, for instance, an existing carport is diverted to form an aluminum terrace as an independent structure attached to the building. Between the independent structure 1 and the above-mentioned housing A, a swing deflection gap B is arranged to allow wind pressure swing or snow deflection at the free end of the roof in a non-contact state with the housing. On the free end of the roof, a mounting frame 2 is arranged in series in the longitudinal direction of the free end, and a high-elasticity extensible closing member is provided which fixes one end in the width direction on the free end side of the mounting frame 2 and projects widely toward the housing A side, and elastically presses the tongue-shaped tip 43 against the housing A so as to be slidable in the vertical direction to close the swing deflection gap B.

[0011] In this example, the independent structure A includes a pair of columns 11 made of aluminum extruded materials, and a roof 12 in which aluminum extruded materials are also arranged in a lattice pattern within an outer frame of the roof made of aluminum extruded materials, and a transparent or opaque roof panel such as a polycarbonate or aluminum roof panel is placed and fixed on the upper surface. The pair of columns 11 are erected at a position separated from the housing A in parallel with the housing A, and the roof 12 is placed and fixed on a pair of beams that are upwardly inclined from each of the pair of columns 11 toward the housing A side and fixed at one end. Thus, with the free end of the roof located at the upper end of the upward inclination on the housing A side, the roof 12 is supported by the pair of columns 11.

[0012] At this time, the erection of the pair of columns 11 is carried out by constructing the terrace of the independent structure A with the total dimension of the depth width of the upwardly inclined roof 12 and the width of the swing deflection gap B as the position separated from the housing A. In this installation state, the swing deflection gap B is arranged between the independent structure 1 and the housing A, and the independent structure 1 is constructed as an independent installation that is constructed independently of the housing A by the support of the pair of columns 11 without being fixed to or supported by the housing A.

[0013] Therefore, when the terrace of the independent structure 1 is subjected to external forces such as the uplifting load of wind pressure and the load of accumulated snow, the roof 12 will swing and deflect in the state of being supported by the columns 11. Since the swinging and deflection of the roof 12 occur in the swinging and deflection gap B, even if the swinging and deflection of the roof 12 occur, the free end of the roof will move vertically independently of the building body A, and as a result, the free end of the roof will not come into contact with the building body A. Therefore, the swinging and deflection of the roof 12 caused by the uplifting load of wind pressure and the load of accumulated snow are actively tolerated.

[0014] In this example, the reference width of the swinging and deflection gap B, that is, the width set as the reference during construction, is 8 - 12 cm, and in this example, it is 10 cm. Using this 10 cm as the reference width from the tip of the free end of the roof to the wall surface of the building body A, the terrace of the independent structure 1 is constructed.

[0015] The swinging and deflection gap B is blocked by a blocking member 4 so as to cover it, preventing the intrusion of rainwater into the swinging and deflection gap B as much as possible and having durability without being damaged. The blocking member 4 is made of a wide plate-shaped molding material made of a highly elastic and stretchable material such as rubber or soft synthetic resin, and its width is 1.7 - 2 times the reference width of the swinging and deflection gap. In this example, the width of the blocking member is more than 18 cm.

[0016] At this time, in this example, the closing member 4 is made of an elastomeric molding material, particularly an extrusion molding material, and has a high degree of the above-mentioned high elastic extensibility, so as to have a preferable rainwater intrusion prevention effect and durability. The thickness of the closing member 4 is, for example, 1 cm to several millimeters on the outer side, that is, the roof side, and gradually decreases toward the building body side so that the tongue-shaped tip 43 on the building body side is, for example, several millimeters to about 1 to 2 mm, having a gradually decreasing thickness. Further, the closing member 4 in this example is provided with, for example, a fitting strip 41 integrally formed downward in a series on the outer side thereof to have a T-shaped cross section, and L-shaped engaging strips 42 are arranged in a series downward on the lower surface at the middle in the width direction thereof. An abutting strip 44 that abuts against the building body together with the tongue-shaped tip 43 is arranged in the vicinity of the tongue-shaped tip 43. Furthermore, a water draining projection piece 45 that slopes downward is arranged on the outer side of the T-shaped fitting strip 41, that is, toward the upper surface of the roof 12, and is integrally formed, so as to be the above-mentioned wide plate shape.

[0017] The fixing of the closing member 4 to the mounting frame 2 in this example is performed by arranging a fitting groove on one of the mounting frame 2 and the closing member 4 and a fitting strip on the other, and performing the fitting and fixing thereof. The fitting groove 24 in this example is arranged on the upper surface of the mounting frame 2 made of an aluminum extrusion material, and the fitting strip 41 is arranged on the lower surface of the closing member 4. These are fitted, and fixing means such as screws and adhesives are used as necessary. In this example, the screw 5 from the lower surface of the fitting groove is screwed into the fitting strip 41 of the closing member 4 to perform the fixing.

[0018] Further, in this example, on the building body side of the mounting frame 2 at the free end of the roof, an intermediate frame or intermediate fitting that holds the closing member 4 at an intermediate position in the protruding direction and restricts the protruding direction of the closing member is provided. In this example, it is provided with an intermediate fitting 3 made of, for example, stainless steel or an aluminum extrusion material. At this time, the holding of the closing member 4 to the intermediate fitting 3 is performed by engaging strips or engaging portions on each L-shaped opening in opposite directions on the intermediate fitting 3 and the closing member 4. In this example, the engaging strip 42 is arranged on the closing member 4, and the engaging portion 32 is arranged on the intermediate fitting 3, and the engagement is performed by the engagement of the engaging strip 42 and the engaging portion 32.

[0019] In this example, the mounting frame 2 includes an L-shaped leg strip 21 inside the roof surface, a tip L-shaped leg strip 22 disposed opposite to the L-shaped leg strip 21 with a slightly higher standing height, and an end frame located at the free end of the roof (corresponding to the front frame when viewed as a carport in the independent structure of this example where the existing carport is diverted to the terrace, so the end frame may be referred to as the front frame) 13. By protruding a pair of L-shaped opposing ridges 23 upward from the end frame 13, a fitting groove 24 having a C-shaped cross-section is formed. The tip of the tip L-shaped leg strip 22 is provided with a standing fixing strip 25 that stands up so as to form an upward inclined surface or an upward curved surface.

[0020] That is, in this example, since the end frame 13 uses the existing carport, a rib 14 for hooking engagement for installing an upward clasp connecting fitting on its upper surface is provided. The L-shaped leg strip 21 is hooked and engaged with the rib 14, and the L-shaped leg strip 21 and the tip L-shaped leg strip 22 are placed on the upper surface of the end frame 13 for arrangement so that the rib 14 is used as a connecting rib for fixing the mounting frame 2. At this time, the mounting frame 2 is fixed by, for example, screwing the intermediate fitting 3 to the standing fixing strip 25 so as to surround the end frame 13 together with the intermediate fitting 3 and sandwich the end frame 13 on two sides.

[0021] In this example, the intermediate fitting 3 is a plate shaped like a letter "V" that includes a vertically wide fixing portion 31 that overlaps, for example, partially in the vertical direction with the descending end surface 15 that overlaps with the upright fixed bar 25 of the mounting frame 2 and forms an inclined or curved surface toward the underside of the roof arranged on the end frame 13, and an engagement portion 32 that is bent at the upper end of the fixing portion 31 toward the inside of the roof 12 surface to form the above-mentioned horizontal L-shape. The intermediate fitting 3 has its fixing portion 31 bent toward the inside of the roof 12 surface to form the above-mentioned horizontal L-shape. 5, and the engagement portion 32 is screwed 5 to the upright fixed strip 25 of the mounting frame 2, thereby integrating the intermediate metal fitting 3 with the mounting frame 2, and overlapping the fixing portion 31 with the inclined or curved surface forming the descending end surface 15 of the end frame 13, so that the integrated mounting frame 2 and intermediate metal fitting 3 surround and clamp the end frame 13, thereby fixing the mounting frame 2 and intermediate metal fitting 3 together, by hooking and engaging the L-shaped leg strip 21 of the mounting frame with the rib 14 and screwing 5 to the descending end surface 15 of the intermediate metal fitting 3. Therefore, in this example, the mounting frame 2 is stably and securely fixed without adopting a structure such as screwing it directly to the end frame 13, which may allow rainwater to seep into the terrace roof. The end frame 13 has an extension piece that extends upward at the end on the frame body side, as shown in FIG. 5. The extension piece of the end frame 13 is a plate-like portion that extends obliquely upward at the end of the end frame 13. The extension piece of the end frame 13 has an obliquely upward extending portion that extends upward at an upward incline toward the body at the end of the body side of the end frame 13, and a bent extending portion that bends away from the body after the obliquely upward extending portion extends upward. As a result, the extension piece of the end frame 13 extends upward at the end of the body side of the end frame 13, and then bends and extends away from the body.

[0022] The fixing of one end in the width direction of the closing member 4 to the mounting frame 2 arranged on the end frame 13 is performed by fitting and fixing the T-shaped fitting strip 41 of the closing member 4 into the C-shaped fitting groove 24 of the mounting frame 2. Also, the holding of the intermediate position in the protruding direction of the closing member 4 is performed by engaging the L-shaped engaging strips 42 arranged in series downward on the lower surface in the middle in the width direction of the closing member 4 with the L-shaped engaging portion 32 of the intermediate fitting 3 in a meshing manner. Thus, the closing member 4 utilizes its high elastic extensibility in its material to elastically press the tongue-shaped tip 43 against the housing A slidably in the vertical direction. On the other hand, in the vicinity of the tongue-shaped tip 43, that is, below the tongue-shaped tip 43, for example, an abutting strip 44 arranged in a C shape with the tongue-shaped tip 43 elastically presses against the housing in a manner of supporting the tongue-shaped tip 43 from below, so that the elastic pressing of the tongue-shaped tip 43 against the housing in the vertical sliding manner is made as much as possible into a line contact.

[0023] FIG. 6 shows another example, in which the fitting grooves 24 and the mating ribs 41 of the closing member 4 are fitted and fixed to the mounting frame 2 by arranging the fitting grooves 24 in an inverted T-shape on the rear surface of the mounting frame 2 made of extruded aluminum so as to open to the body side, and arranging the mating ribs 41 on the underside of the closing member 4 so as to protrude in an inverted T-shape on the roof 12 side, and fitting these together. In this case, the mounting frame 2 is integrally molded with a mounting portion 26 that is placed on the upper surface so as to cover the rib 14 of the end frame 13, and a fixing portion 27 that overlaps the mounting portion 26 with the descending end surface 15 of the end frame 13 and is fixed to the descending end surface 15 by a screw 5. Thus, although the mounting frame 2 is directly screwed to the end frame, the lower end surface 15 located on the underside of the blocking member 4 is used as the fixing point, so the possibility of rainwater infiltrating into the roof of the terrace is also eliminated. Also, the blocking member 4 is fitted and fixed by the lateral fitting of the fitting groove 24, which forms a vertical surface formed on the end frame 13, and the fitting strip 41 on the underside of the blocking member 4 on the roof 12 side. Also, as a result of bending the tongue-shaped tip 43 of the blocking member 4 from the blocking member 4 to the body A side, the tongue-shaped tip 43 of the blocking member 4 is elastically pressed against the body A in line contact without using the intermediate frame or intermediate metal fitting or the counter-joint strip in this example. Note that the end of the blocking member 4 on the roof 12 side is located on the upper surface of the mounting frame 2, so the arrangement of the water cut-off piece is omitted. Since the rest is the same as the above example, the same reference numerals are used and repeated explanations are omitted.

[0024] Therefore, the terrace of the independent structure 1 in this example can prevent rainwater from entering the rocking and deflection gap B between the roof 12 and the building body A as much as possible by the blocking member 4 closing the rocking and deflection gap B. Even if it is impossible to completely prevent the rainwater from entering, an effective rainproof measure can be taken when using the terrace on a rainy day, including the daily access between the building and the terrace. At this time, since the wide plate-shaped blocking member 4 made of the elastomer is used, the rocking and deflection gap B can be closed in good appearance without damaging the appearance of the terrace of the independent structure 1 or the building body A, and it can be made to have long-term durability without damage. Also, even if the roof 12 sways or deflects due to the load of wind pressure or snow load, since the tongue-shaped tip 43 of the blocking member 4 is not fixed to the building body A but is elastically pressed in a vertically slidable manner, the blocking member 4 follows the movement of the free end of the roof and slides in the vertical direction. As a result, the blocking member 4 will not be damaged as in the case of using a hard member. Also, even if the blocking member 4 is deformed in a hanging state from the free end of the roof due to the load of snow load, if the load is removed, it can be easily restored to the normal upward state by pressing the blocking member 4 upward from below using a rod or the like as necessary.

[0025] The illustrated example is as described above. However, the independent structure may be attached to the opening or the wall surface of the building, such as a sunroom or a cycle port, other than the above-mentioned terrace. In the case of an independent structure having an opening on the building side like the sunroom, a gap is arranged between the vertical wall, the floor, and the free end of the roof in the same manner as the free end of the roof and the building, and the gap is closed by a closing member. The fitting and fixing of the closing member to the mounting frame is performed by arranging, for example, the above-mentioned T-shaped upright strip on the mounting frame and the C-shaped fitting groove engaging with the upright strip on the closing member, and performing the fitting in the same manner as above. Instead of the intermediate fitting, an intermediate frame is used. At this time, the intermediate frame is installed in series in the longitudinal direction of the free end of the roof, and for example, has the same cross-sectional shape as the intermediate fitting and is provided with the above-mentioned engaging portion. At this time, when fixing, when using the mounting frame, the intermediate frame or the intermediate fitting, the end frame is provided with the above-mentioned connecting rib, and the end frame and the mounting frame or the intermediate frame and the intermediate fitting are of a structure suitable for the fixing. In the implementation of the present invention, including the building, the independent structure, the free end of the roof, the swinging and deflecting gap, the mounting frame, the closing member, the fitting groove used as needed, the fitting strip, the intermediate frame or the intermediate fitting, the engaging strip or the engaging portion, the abutting strip, the extruded molding material of the elastomer, the reference width of the swinging and deflecting gap, etc., each specific shape, structure, material, dimension, the relationship between these, and the addition to these can be in various forms as long as they do not conflict with the gist of the above invention.
