Independent structures and closing elements attached to buildings

Abstract

To prevent infiltration of rainwater as much as possible, by effectively processing a cavity generated between a roof free end and a skeleton with an excellent appearance in a building-attached terrace constructed without being fixed to the building skeleton.SOLUTION: A roof free end of a terrace 1 is installed separated by about 10 cm from a skeleton, and a rocking deflective cavity B is arranged between the roof free end and the skeleton A for allowing rocking and deflection of a roof 12 by a flapping load and a snowfall load of wind pressure. A wide plate-like blocking-up member 4 by an extrusion molding material of an elastomer is projected upward on the skeleton A side from the roof free end, and its tongue-like tip 43 is elastically brought into pressure contact with the skeleton A so as to freely slide in the vertical direction, thereby preventing infiltration of rainwater in between the skeleton A and the terrace 1 as much as possible by the blocking-up member 4. The blocking-up member 4 has durability without being damaged because of having high elastic extensibility.SELECTED DRAWING: Figure 4

Description

[Technical Field]

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

[0002] In structures such as terraces and sunrooms that are constructed on pillar support at the front of a building opening or wall, the pillar-supported roof end on the side of the structure is fixed to the structure using fixing metal fittings such as screws and bolts, thereby ensuring the fixing strength of the roof against wind loads and snow loads through the pillar support and fixation to the structure.Patent document 1 listed below describes a structure that is fixed to the structure by providing curved surfaces that can rotate freely between the structure and roof connecting frames, so that even if the roof inclination angle differs in relation to the structure installation space, the structure can be fixed to the structure in accordance with the roof inclination angle.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-257013 Summary of the Invention [Problem to be solved by the invention]

[0004] In this case, as mentioned above, it is possible to ensure the roof's fixing strength against wind loads and snow loads, but by using fixing metal fittings such as screws and bolts to fix the roof to the structure, it cannot be denied that rainwater may seep in through the fixing points to the structure and damage the weatherproofing of the wall.In addition, with the recent enforcement of the Housing Defect Liability Act, there is a tendency for home builders and home builders to avoid fixing structures to the structure using fixing metal fittings such as screws and bolts, which may affect weatherproofing.However, clients often wish to install terraces, sunrooms, etc.

[0005] Therefore, it is necessary to make these structures independent structures attached to buildings, which are supported by supports without being fixed to the building opening or the front of the wall, and when they are made into such independent structures, it becomes necessary to deal with the gap that occurs between the free end of the roof and the building structure effectively and in a good appearance.

[0006] The present invention was made in consideration of the above circumstances, and its problem to be solved is to provide an independent structure attached to a building and a support structure for the independent structure attached to a building that can effectively and aesthetically deal with the gap that occurs between the free end of the roof of the independent structure and the main body. [Means for solving the problem]

[0007] The independent structure attached to a building of the present invention comprises a roof, a blocking member protruding from the roof toward a main body, and a mounting frame, the base end portion of the blocking member being screwed to the mounting frame, the roof comprising an end frame provided at the end on the main body side, the mounting frame being fixed above the end frame, the end frame comprising an extension piece extending upward at the end on the main body side, the extension piece extending upward at the end of the end frame on the main body side, and then bending and extending in the opposite direction from the main body. [Effects of the Invention]

[0008] Because the present invention is configured as described above, it is possible to provide an independent structure attached to a building, such as a carport or cycle port, whose roof is supported by pillars, by arranging a swinging deflection gap for the free end of the roof between the free end of the roof and the frame, and this swinging deflection gap actively allows the free end of the roof to swing without contacting the frame, eliminating the possibility that the free end of the roof will swing up and down due to wind pressure or snow loads, and that the free end of the roof will come into contact with the wall surface of the frame and damage the free end of the roof or the wall surface of the frame.On the other hand, a closing member is arranged in the swinging deflection gap between the free end of the roof and the frame to prevent rainwater from entering as much as possible, and this closing member is made of highly elastic and extensible material, and the tongue-shaped tip of the closing member is elastically pressed against the frame so that it can slide up and down in a vertical direction.This makes it possible to provide an independent structure attached to a building in which the swinging deflection gap can be effectively treated with a good appearance, while providing long-term durability. [Brief explanation of the drawings]

[Figure 6] FIG. 10 is a partially enlarged vertical cross-sectional view showing another example. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in more detail below with reference to the drawings. In Figs. 1 to 5, 1 denotes an independent structure attached to a building that is independently constructed by supporting pillars without being fixed to a building opening or the front of a wall. In this example, for example, an existing carport is converted into an aluminum terrace. Between the independent structure 1 and the structure A, there is disposed a swing deflection gap B that allows the free end of the roof to swing under wind pressure or deflect due to snow accumulation without contacting the structure. The independent structure 1 is also equipped with a mounting frame 2 that is disposed in series with the free end of the roof in the longitudinal direction of the free end, and a highly elastic and extensible closing member that has one end in the width direction of the free end fixed to the mounting frame 2 and that protrudes widely toward the structure A, thereby elastically pressing a tongue-shaped tip 43 against the structure A so that it can slide freely in the vertical direction, thereby closing the swing deflection gap B.

[0011] In this example, the independent structure A comprises a pair of posts 11 made of extruded aluminum, and a roof 12 which is made by arranging extruded aluminum in a lattice pattern within an outer frame of the roof made of extruded aluminum, and then mounting and fixing a roof panel, such as a transparent or opaque roof panel made of polycarbonate, aluminum, etc., on the top surface. The pair of posts 11 are installed upright and parallel to the body A at a distance from the outside, and the roof 12 is mounted and fixed to a pair of beams which slope upward from each of the pair of posts 11 towards the body A and have one end fixed thereto, so that the roof 12 is supported by the pair of posts 11, with the free end of the roof located at the tip of the upper side of the upward slope facing the body A.

[0012] In this case, the pair of support columns 11 are installed upright in such a way that the terrace of the independent structure A is constructed at a position spaced apart from the main structure A by the total dimension of the depth width of the upwardly sloping roof 12 and the width of the swinging deflection gap B, and in this installed state the swinging deflection gap B is disposed between the independent structure 1 and the main structure A, and the independent structure 1 is constructed so as to be attached to the building, but is not fixed to or supported by the main structure A, and is installed independently of the main structure A by being supported by the pair of support columns 11.

[0013] Therefore, when the terrace of the independent structure 1 is subjected to external forces such as wind pressure or snow load, the roof 12 will sway or deflect while supported by the supports 11. However, since the swaying and deflection of the roof 12 occurs in the swaying and deflection gap B, even if the roof 12 sways or deflects, the free end of the roof moves up and down independently of the structure A, and as a result, the free end of the roof will not come into contact with the structure A. Therefore, the swaying and deflection of the roof 12 due to wind pressure or snow load is actively tolerated.

[0014] In this example, the standard width of the swing deflection gap B, i.e., the width set as a standard during construction, is 8 to 12 cm, and in this example it is 10 cm, and this 10 cm is used as the standard width from the tip of the free end of the roof to the wall surface of the main body A to construct the terrace of the independent structure 1.

[0015] The swaying deflection gap B is closed by a blocking member 4 so as to cover it, thereby preventing the intrusion of rainwater into the swaying deflection gap B as much as possible and making it durable without causing damage. The blocking member 4 is made of a wide plate-shaped molding material made of a highly elastic and extensible material such as rubber or soft synthetic resin, and its width is 1.7 to 2 times the standard width of the swaying deflection gap, and in this example the blocking member has a width of just over 18 cm.

[0016] In this example, the blocking member 4 is made of an elastomer molding material, particularly an extrusion molding material, and has the above-mentioned high elasticity and extensibility, thereby providing desirable rainwater penetration prevention and durability. The blocking member 4 has a thickness of, for example, 1 cm to several mm on the outer side, i.e., the roof side, and gradually decreases in thickness toward the building frame, with the tongue-shaped tip 43 on the building frame side having a thickness of, for example, several mm to 1 to 2 mm. In addition, the blocking member 4 in this example is provided with, for example, on its outer side, a continuous downward mating rib 41 that is integrally molded to have a T-shaped cross section, and a continuous downward L-shaped engaging rib 42 is arranged on its underside in the middle of its width, and a mating rib 44 is arranged near its tongue-shaped tip 43, which abuts the main body together with the tongue-shaped tip 43.Furthermore, by arranging and integrally molding a water-repelling protrusion 45 that slopes downward toward the outside of the T-shaped mating rib 41, i.e., toward the upper surface of the roof 12, it is made into the above-mentioned wide plate shape.

[0017] In this example, the blocking member 4 is fixed to the mounting frame 2 by arranging an engagement groove on one of the mounting frame 2 and the blocking member 4 and an engagement thread on the other, and then engaging and fixing these together. In this example, the engagement groove 24 is arranged on the upper surface of the mounting frame 2 made of extruded aluminum, and the engagement thread 41 is arranged on the lower surface of the blocking member 4, and these are engaged together, and the fixing is carried out using fixing means such as screws or adhesives as necessary, in this example by threading a screw 5 from the lower surface of the engagement groove into the engagement thread 41 of the blocking member 4.

[0018] In addition, in this example, an intermediate frame or intermediate fitting is provided on the body side of the mounting frame 2 at the free end of the roof, which holds the blocking member 4 at an intermediate position in the protruding direction and regulates the protruding direction of the blocking member; in this example, an intermediate fitting 3 made of, for example, stainless steel or aluminum extrusion is provided.In this case, the blocking member 4 is held on the intermediate fitting 3 by L-shaped engaging strips or engaging portions that open in opposite directions on the intermediate fitting 3 and the blocking member 4, in this example, an engaging strip 42 is provided on the blocking member 4 and an engaging portion 32 is provided on the intermediate fitting 3, and these engaging strips 42 and engaging portions 32 engage with each other.

[0019] In this example, the mounting frame 2 comprises an L-shaped leg 21 on the inside of the roof surface, an L-shaped tip leg 22 at the tip end which is positioned opposite the L-shaped leg 21 and has a slightly higher rising height, and these L-shaped leg 21 and L-shaped tip leg 22 form a pair of L-shaped opposing protrusions 23 which protrude upward from the end frame 13 located at the free end of the roof (in this example, an independent structure in which an existing carport has been converted into a terrace, when viewed as a carport, this corresponds to the front frame of the carport, so the end frame can also be called the front frame) to form an insertion groove 24 with a C-shaped cross section, and an upright fixed rib 25 which rises from the tip of the L-shaped tip leg 22 to form an upwardly inclined or upwardly curved surface.

[0020] That is, in this example, the end frame 13 has been repurposed from the existing carport and is provided with a hooking engagement rib 14 on its upper surface for installing an upward-facing joint connecting fitting, and the rib 14 is used as a connecting rib for fixing the mounting frame 2 by hooking the L-shaped leg bar 21 onto the rib 14 and placing the L-shaped leg bar 21 and the tip L-shaped leg bar 22 on the upper surface of the end frame 13. At this time, the mounting frame 2 is fixed by, for example, screwing the intermediate fitting 3 to the upright fixing bar 25, so that the mounting frame 2 surrounds the end frame 13 together with the intermediate fitting 3 and clamps the end frame 13 on two sides.

[0021] In this example, the intermediate fitting 3 is a katakana L-shaped plate having a wide fixing portion 31 that overlaps the upright fixed bar 25 of the mounting frame 2 and the descending end surface 15 that is arranged on the end frame 13 and forms an inclined or curved surface toward the underside of the roof, and an engaging portion 32 that is bent at the top end of the fixing portion 31 toward the inside of the roof 12 surface to form the above-mentioned horizontal L-shape, and the intermediate fitting 3 is configured such that the fixing portion 31 is in contact with the upright fixed bar 25 of the mounting frame 2 and the descending end surface 15 that is arranged on the end frame 13 and forms an inclined or curved surface toward the underside of the roof, 5, and its engaging portion 32 is fastened with a screw 5 to the upright fixed strip 25 of the mounting frame 2, thereby integrating the intermediate fitting 3 with the mounting frame 2, and by overlapping the fixing portion 31 with the inclined or curved surface forming the descending end face 15 of the end frame 13, the integrated mounting frame 2 and intermediate fitting 3 are fastened together by the hook engagement of the L-shaped leg strip 21 of the mounting frame with the rib 14 and the screw 5 fastening of the intermediate fitting 3 to the descending end face 15, thereby surrounding and clamping the end frame 13. Therefore, in this example, the mounting frame 2 is stably and securely fixed without employing a structure such as directly screwing it to the end frame 13, which could allow rainwater to seep into the terrace roof. The end frame 13 has an extension piece that extends upward at the end facing the frame body, as shown in FIG. 5. The extension piece of end frame 13 is a plate-like portion that extends diagonally upward at the end of end frame 13. The extension piece of end frame 13 has an obliquely upward extending portion that extends upward at an upward slope toward the body at the end of end frame 13 facing the body, and a bent extending portion that, after extending upward, bends in the opposite direction from the body and extends away from the body. As a result, the extension piece of end frame 13 extends upward at the end of end frame 13 facing the body, and then bends in the opposite direction from the body.

[0022] The one widthwise end of the blocking member 4 is fixed to the mounting frame 2 arranged on the end frame 13 by fitting and fixing the T-shaped fitting rib 41 of the blocking member 4 into the fitting groove 24 having a C-shaped cross section of the mounting frame 2, and the blocking member 4 is held in the intermediate position in the protruding direction by engaging in an interlocking manner the L-shaped engaging portion 32 of the intermediate fitting 3 with the L-shaped engaging rib 42 arranged in a downward direction in a continuous manner on the underside of the intermediate widthwise end of the blocking member 4, thereby The blocking member 4 utilizes the high elastic extensibility of its material to elastically press the tongue-shaped tip 43 against the body A so that it can slide freely in the vertical direction, while a mating bar 44 arranged near the tongue-shaped tip 43, i.e., below the tongue-shaped tip 43, so as to form a V-shape with the tongue-shaped tip 43, supports the tongue-shaped tip 43 and similarly presses it against the body, thereby making the elastic pressing of the tongue-shaped tip 43 against the body so that it can slide freely up and down, as much as possible, a line contact.

[0023] FIG. 6 shows another example in which the fitting grooves 24 and the fitting ribs 41 of the closing member 4 are fitted and fixed to the mounting frame 2 by the fitting grooves 24 being arranged in an inverted T shape on the rear side of the mounting frame 2 made of extruded aluminum so that the grooves are open to the body side, and the fitting ribs 41 are arranged on the underside of the closing member 4 so as to protrude in an inverted T shape towards the roof 12, and these are fitted together. In this example, the mounting frame 2 is integrally formed 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 face 15 of the end frame 13 and is fixed to the descending end face 15 with a screw 5, and Therefore, although the mounting frame 2 is screwed directly to the end frame, the lower end surface 15 located on the underside of the blocking member 4 is used as the fixing point, similarly eliminating the possibility of rainwater seeping into the terrace roof. The blocking member 4 is fixed in place by the horizontal engagement of the fitting groove 24, which forms a vertical surface on the end frame 13, with the fitting strip 41 on the underside of the blocking member 4 facing the roof 12. Furthermore, since the tongue-shaped tip 43 of the blocking member 4 is bent from the blocking member 4 toward the main body A, the tongue-shaped tip 43 of the blocking member 4 is elastically pressure-welded to the main body A through line contact without the use of the intermediate frame, intermediate fitting, or mating strip. Since the roof 12-side end of the blocking member 4 is located on the top surface of the mounting frame 2, the placement of a water-repellent projection is omitted. Other than this, the same reference numerals are used and redundant explanations will be omitted.

[0024] Therefore, in the terrace of the independent structure 1 of this example, the closing member 4 closes the swinging deflection gap B between the roof 12 and the body A, making it possible to prevent rainwater from entering through the swinging deflection gap B as much as possible, and even if it is not possible to completely prevent rainwater from entering, it can provide effective weatherproofing when the terrace is used on rainy days, including daily entry and exit of the building and the terrace.In this case, because the wide plate-shaped closing member 4 made of the elastomer is used, the swinging deflection gap B is closed in an attractive manner, and the appearance of the terrace of the independent structure 1 and the body A is not marred, and they can be made to have long-term durability without damage. Furthermore, even if the roof 12 sways or bends due to wind pressure or snow load, the tongue-shaped tip 43 of the blocking member 4 is not fixed to the main body A, but is elastically pressed against it so that it can slide freely in the vertical direction.As a result, the blocking member 4 follows the movement of the free end of the roof and slides in the vertical direction, and the blocking member 4 will not be damaged, as would be the case if a hard member were used, for example.Furthermore, even if the blocking member 4 is deformed so that it hangs down from the free end of the roof due to the snow load, once the load is removed, the blocking member 4 can be easily returned to its normal upward state by pressing upward from below, for example using a rod, as necessary.

[0025] The illustrated examples are as described above, but the independent structure may be something other than the terrace, such as a sunroom or cycle port, which is attached to an opening in a building or to a wall of a building; in the case of an independent structure with an opening on the side of the building frame, such as the sunroom, a gap may be provided between the free end of the vertical wall or floor and the building frame in the same manner as the free end of the roof, and the gap may be closed with a closing member; the closing member may be fitted and fixed to the mounting frame by fitting, for example, the T-shaped upright strip on the mounting frame and the C-shaped cross-section fitting groove on the closing member that engages with the upright strip, in the same manner as above; an intermediate frame may be used instead of the intermediate metal fitting, and in this case the intermediate frame may be a continuous piece of metal, for example a piece of metal with a cross-section In carrying out the present invention, the specific shapes, structures, materials, dimensions, relationships between these, and additions to these of the building, independent structure, free roof end, swinging deflection gap, mounting frame, closing member, fitted grooves used as needed, mating strips, intermediate frame or intermediate fitting, engaging strips or engaging portions, mating strips, extruded elastomer material, standard width of the swinging deflection gap, etc., can take various forms as long as they do not deviate from the gist of the invention.
