Description

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

Structures such as terraces and sunrooms that are constructed on the front of building openings or wall surfaces with supporting columns shall be fixed to the building frame using fasteners such as screws and bolts. By supporting the pillars and fixing the frame, the fixing strength of the roof against wind pressure swing load and snow load is secured. A rotatable curved surface is interposed in the structure so that, for example, even if the roof inclination angle differs due to the relationship with the structure installation space, it can be fixed to the frame according to the roof inclination angle. be.

JP-A-2004-257013

In this case, it is possible to secure the fixing strength of the roof against the wind load and snow load as described above. We cannot deny the possibility that it will infiltrate and damage the rain closing of the wall surface, and recently, due to the enactment of the Housing Defect Liability Act, housing manufacturers and home builders may have an impact on the rain closing. While there is a tendency to avoid fixing structures to the skeleton using fixing metal fittings such as screws and bolts, owners often desire the installation of terraces, sunrooms, and the like.

Therefore, it is necessary to make these structures independent structures attached to the building, which are independently constructed by supporting columns without fixing the frame to the front of the building opening or wall surface. It is necessary to treat the gaps between the frame and the frame effectively and with good appearance.

The present invention has been made in view of the above circumstances, and the problem to be solved is to provide a building attachment structure capable of effectively treating the gap between the free end of the roof and the building frame of an independent structure with good appearance. To provide a support structure for an independent structure and an independent structure attached to a building.

The independent structure for building attachment according to the present invention is for building attachment, and includes a roof supported by a pair of pillars arranged in the width direction of the building body apart from the building body, with the free ends directed toward the building body. The independent construction includes a closing member projecting from the roof free end side of the roof toward the skeleton, the closing member elastically presses the lower surface of the tip side along the wall surface of the skeleton, and the tip At least the tip side is bent downward between the side and the roof free end side, and the base end side of the closing member is fixed to the roof free end side.

Further, in the independent structure for attachment to a building of the present invention, a drain projecting piece that slopes downward from the roof free end side of the closing member may be formed.

Further, in the independent structure for attachment to a building of the present invention, a contact line extending in an out-of-plane direction from the lower surface of the free end side of the closing member may be formed.

A support structure for an independent structure for building attachment according to the present invention is a building attachment comprising a roof supported by a pair of pillars spaced apart from a skeleton and disposed in the width direction of the skeleton, with free ends facing the skeleton. The support structure for an independent building for a building, comprising a closing member protruding from the roof free end side of the roof toward the frame, wherein the closing member elastically presses the lower surface of the tip side along the wall surface of the frame. In addition, at least the tip end side is bent convexly downward between the tip end side and the roof free end side, the base end side of the blocking member is fixed to the roof free end side, and the projection length of the blocking member is is set longer than the distance between the roof free end and the frame, and the closing member is not fixed to the frame.

Since the present invention is configured as described above, for example, it is possible to install an independent structure such as a carport, a cycle port, or the like, in which the roof is supported by pillars, and a gap between the free end of the roof and the building body is provided for swing deflection of the free end of the roof. It is attached to the building by placing and constructing, and the swing deflection gap positively allows the swinging of the free end of the roof in a non-contact state with the frame, and the swinging load of the wind pressure and the load of the snow load can be applied to the free roof. The free end of the roof swings vertically to eliminate the possibility that the free end of the roof contacts the wall surface of the frame and damages the free end of the roof or the wall surface of the frame. In addition, a blocking member is arranged so as to prevent rainwater from entering as much as possible, and the blocking member is made highly elastic and extensible, and the tongue-shaped tip arranged on the blocking member is vertically slidable with respect to the building body. It is possible to provide an independent structure attached to a building in which the oscillating deflection gap can be treated effectively and aesthetically with long-term durability by freely elastically press-contacting.

It is a front view of a terrace. It is a top view of a terrace. It is a longitudinal cross-sectional view of a terrace. 4 is a partially enlarged longitudinal sectional view of FIG. 3; FIG. It is an exploded longitudinal cross-sectional view showing the installation state of the closing member. FIG. 11 is a partially enlarged longitudinal sectional view showing another example;

The present invention will be explained more specifically according to the examples of the drawings. , For example, it is an independent structure attached to a building that is made into an aluminum terrace by diverting an existing carport, and the independent structure 1 is between the above-mentioned frame A and the wind pressure swing or snow accumulation of the free end of the roof. A mounting frame 2 arranged in series in the longitudinal direction of the free end at the free end of the roof, and a width of the free end side of the mounting frame 2, while arranging a swinging deflection gap B for allowing the deformation in a non-contact state with the building frame. By fixing one end in the direction and protruding broadly toward the body A side, the tongue-like tip 43 is elastically press-contacted to the body A so as to be slidable in the vertical direction, and is highly elastically stretched to close the swing deflection gap B. and an elastic occluding member.

In this example, the independent structure A comprises a pair of columns 11 made of extruded aluminum, and aluminum extruded members arranged in a grid pattern in the outer frame of the roof made of extruded aluminum. A roof 12 on which a transparent or opaque roof panel made of aluminum or the like is placed and fixed, and a pair of pillars 11 are erected and installed in parallel with the frame A at a position separated from the frame A to the outside, and each of the pair of supports 11 is installed. By placing and fixing the roof 12 on a pair of beams inclined upward from the support 11 to the side of the frame A and fixed at one end, the free end of the roof located at the upper tip of the upwardly inclined upper side is set to the side of the frame A, and the pair of beams The roof 12 is supported by the pillars 11. - 特許庁

At this time, the erect installation of the pair of pillars 11 is carried out on the terrace of the independent structure A, with the total dimension of the depth width of the upwardly sloping roof 12 and the width of the swing deflection gap B being separated from the frame A. By constructing, the swing deflection gap B is arranged between the building body A in its installed state, and the independent structure 1 is constructed so as to be attached to the building, but is fixed to the building body A. It is an independent installation that is constructed independently of the frame A by the support of the pair of struts 11 without any support.

Therefore, when the terrace of the independent structure 1 receives an external force such as a wind load or a snow load, the roof 12 swings or bends while the pillars 11 are supported. Since the rocking and bending are performed in the rocking and bending gap B, even if the roof 12 rocks and bends, the free end of the roof moves vertically independently of the frame A, resulting in the roof bending. The free end does not come into contact with the frame A, therefore, the rocking and bending of the roof 12 due to the wind load and snow load are positively accepted.

In this example, the swing deflection gap B has a reference width, that is, a width to be installed as a reference at the time of construction, which is 8 to 12 cm, and in this example is 10 cm. The terrace of the independent structure 1 is constructed with the reference width up to the wall surface of the frame A.

The rocking deflection gap B is closed by a closing member 4 so as to cover it, thereby preventing rainwater from entering the rocking deflection gap B as much as possible and ensuring durability without damage. The closing member 4 is made of a wide plate-like molded member made of a highly elastic and extensible material such as rubber or soft synthetic resin. .7 to 2 times, and in this example the closure member has a width of just over 18 cm.

At this time, in this example, the closing member 4 is made of an elastomer molded material, particularly an extruded material, and has a high degree of high elastic extensibility as described above. It has durability. The blocking member 4 has a thickness of, for example, 1 cm to several mm on the outside, that is, on the roof side, and gradually decreases toward the building frame side so that the tongue-like tip 43 on the building body side is, for example, several mm thick. The thickness is gradually reduced to about 1 to 2 mm. In addition, the closing member 4 of this example is provided with, for example, a downward series of fitting strips 41 integrally formed on the outer side thereof to have a T-shaped cross section, and a series of downward L-shaped fitting strips 41 on the lower surface in the middle of the width direction. An engaging ridge 42 having a shape is arranged, and in the vicinity of the tongue-shaped tip 43, a contacting ridge 44 is arranged to contact the body together with the tongue-shaped tip 43, and the T-shaped fitting is provided. The above-mentioned wide plate shape is formed by arranging and integrally forming the draining projecting piece 45 inclined downward toward the outside of the row 41, that is, toward the upper surface of the roof 12. As shown in FIG.

In this example, the blocking member 4 is fixed to the mounting frame 2 by arranging a fitting groove on one of the mounting frame 2 and the blocking member 4 and a fitting strip on the other, and by fitting and fixing them. In this example, the fitting groove 24 is arranged on the upper surface of the mounting frame 2 made of extruded aluminum, and the fitting strip 41 is arranged on the lower surface of the closing member 4, respectively. If necessary, a screw, an adhesive, or other fixing means, in this example, a screw 5 from the bottom surface of the groove to be fitted, is screwed into the fitting strip 41 of the closing member 4 to fix the fitting. As I went.

Further, in this example, an intermediate frame or an intermediate fitting for holding the closing member 4 at an intermediate position in the projecting direction on the skeleton side of the mounting frame 2 at the free end of the roof and restricting the projecting direction of the closing member; In this example, an intermediate metal fitting 3 made of, for example, stainless steel or extruded aluminum is provided. In this example, the engagement strip 42 is arranged in the closing member 4 and the engagement portion 32 is arranged in the intermediate metal fitting 3, and these It is assumed that this is achieved by the engagement between the engagement strip 42 and the engagement portion 32 .

The mounting frame 2 in this example includes an L-shaped leg 21 on the inner side of the roof surface, an end L-shaped leg 22 on the tip end side arranged opposite to the L-shaped leg 21 with a slightly higher standing height, These L-shaped leg strips 21 and tip L-shaped leg strips 22 form an end frame located at the free end of the roof (in the independent construction of this example in which an existing carport is converted to a terrace, when viewed as a carport, it is A fitting groove 24 having a C-shaped cross section by protruding a pair of L-shaped opposed ridges 23 upward from the end frame 13, since it corresponds to the front frame. , The tip of the L-shaped leg 22 is provided with an upright fixed ridge 25 erected to form an upwardly inclined surface or an upwardly curved surface.

That is, in the present example, the end frame 13 is provided with a rib 14 for hook engagement on which an upward palm joint fitting is installed on the upper surface, since the existing carport was diverted. The L-shaped leg 21 is engaged with the rib 14 so that the rib 14 is used as a connecting rib for fixing the mounting frame 2, and the L-shaped leg 21 and the tip L-shaped leg 22 are engaged. is placed on the upper surface of the end frame 13, and at this time, the mounting frame 2 is mounted on the intermediate fitting 3 by screwing the intermediate metal fitting 3 to the standing fixing strip 25, for example. It surrounds the end frame 13 together with the metal fitting 3 and clamps the end frame 13 on two sides to fix it.

In this example, the intermediate fitting 3 has a lowering end surface 15 which overlaps with the upright fixing strip 25 of the mounting frame 2 and forms an inclined surface or a curved surface toward the lower surface of the roof arranged on the end frame 13. In addition, for example, a fixed part 31 with a wide vertical width that partially overlaps in the vertical direction, and an engaging part 32 in which the upper end of the fixed part 31 is bent toward the inside of the roof 12 surface to form the lateral L shape. The fixing portion 31 of the intermediate fitting 3 is arranged so as to overlap the upright fixing strip 25 of the mounting frame 2 and the lowering end surface 15 of the end frame 13, thereby engaging them. By screwing the joining portion 32 to the upright fixing strip 25 of the mounting frame 2 with screws 5 , the intermediate fitting 3 is integrated with the mounting frame 2 and the fixing portion 31 is attached to the lower end surface of the end frame 13 . By overlapping the inclined surface or curved surface forming 15, the integrated mounting frame 2 and intermediate fitting 3 are hooked to the rib 14 of the L-shaped leg 21 of the mounting frame and the intermediate fitting 3 is lowered. The end frame 13 is surrounded and held by screws 5 fixed to the end face 15 to fix the end frame 13 . Therefore, in this example, the mounting frame 2 does not have a structure in which it is screwed directly to the end frame 13, which leaves the possibility of rainwater entering the roof of the terrace. It is assumed to be fixed stably and reliably.

One widthwise end of the closing member 4 is fixed to the mounting frame 2 arranged on the end frame 13 by fitting the closing member 4 into the fitting groove 24 of the mounting frame 2 having a C-shaped cross section. The intermediate position of the closing member 4 in the projecting direction is held by fitting and fixing the joint 41 , and the L-shaped engaging portion 32 of the intermediate fitting 3 holds the closing member 4 in the width direction. L-shaped engagement strips 42 arranged downward in series on the lower surface of the middle are engaged in a meshing fashion, whereby the closure member 4 utilizes the high elastic stretchability of its material. Then, the tongue-shaped tip 43 is elastically pressed against the body A so as to be slidable in the vertical direction. The opposing ribs 44 arranged to form a shape likewise elastically press the tongue-shaped tip 43 against the skeleton to support the tongue-shaped tip 43, thereby allowing the tongue-shaped tip 43 to slidably elastically press against the skeleton. Line contact is used as much as possible.

FIG. 6 shows another example, in which the closing member 4 is fitted and fixed to the mounting frame 2 by means of a fitting groove 24 and a fitting strip 41, and the fitting groove 24 is attached to a mounting frame made of extruded aluminum material. 2 is arranged in an inverted T shape so that the skeleton side is open on the rear surface of the body side of the closing member 4, and the fitting strip 41 is arranged on the lower surface of the closing member 4 so as to protrude in an inverted T shape toward the roof 12 side. In this case, the mounting frame 2 has a mounting portion 26 mounted on the upper surface so as to cover the ribs 14 of the end frame 13, and the mounting portion 26 from the mounting portion 26. , and a fixing portion 27 superimposed on the lowering end surface 15 of the end frame 13 and fixed to the lowering end surface 15 by screws 5, thereby forming the mounting frame 2 into a single piece. Even though it is screwed directly to the end frame, since the lowering end surface 15 located on the lower surface of the closing member 4 is fixed, the possibility of rainwater entering the inside of the roof of the terrace is similarly eliminated. In addition, the closing member 4 is fixed by fitting the fitting groove 24 forming a vertical surface formed on the end frame 13 and the fitting line 41 on the lower surface of the closing member 4 on the side of the roof 12 sideways. Also, as a result of bending the tongue-like tip 43 of the blocking member 4 from the blocking member 4 toward the skeleton A, in this example, without using the intermediate frame or the intermediate fitting or the above-mentioned connecting strip, The tongue-like tip 43 of the closing member 4 is elastically pressed against the body A in a line contact manner. Since the end of the blocking member 4 on the side of the roof 12 is located on the upper surface of the mounting frame 2, the arrangement of the draining projecting piece is omitted. Since the remainder is the same as the above example, the same reference numerals are given and redundant explanations are omitted.

Therefore, in the terrace of the independent structure 1 of this example, the closing member 4 closes the swing deflection gap B between the roof 12 and the frame A, and rainwater enters from the swing deflection gap B as much as possible. Even if it is not possible to completely prevent the infiltration of rainwater, it is possible to effectively stop the rain when using the terrace in rainy weather, including entering and exiting the building and the terrace on a daily basis. Since the wide plate-shaped closing member 4 made of the above elastomer is used, the swing deflection gap B is closed with good appearance, and the appearance of the terrace and the frame A of the independent construction 1 is not damaged, and it can be used for a long time without damage. durability. In addition, even if the roof 12 swings or bends due to the load of wind pressure or snow load, the tongue-like tip 43 of the closing member 4 is not fixed to the frame A and is elastically press-contacted so that it can slide vertically. Since the closing member 4 follows the motion of the free end of the roof and slides in the vertical direction, the closing member 4 is not damaged unlike when a hard member is used. Also, even if the closing member 4 is deformed from the free end of the roof by the snow load, if the load is removed, the closing member 4 can be removed from below by using a rod or the like as necessary. 4 is pushed upward, it is possible to easily return to the upward normal state.

The illustrated examples are as described above, but the independent structure may be other than the above-mentioned terrace, which is attached to the opening of the building or the wall surface of the building, such as a sunroom or a cycle port. In an independent structure having an opening on the building frame side, a gap is arranged between the vertical wall and the free end of the floor according to the free end of the roof and the building frame, and the gap is closed with a closing member. In order to fit and fix the closing member to the mounting frame, for example, the T-shaped standing strip is arranged on the mounting frame, and the fitting groove having the C-shaped cross section that engages with the rising strip is arranged on the closing member. and using an intermediate frame in place of the intermediate fitting, in which case the intermediate frame is installed in series in the longitudinal direction of the free end of the roof, e.g. It has the same shape as the intermediate fitting and has the engaging portion, and when the mounting frame, the intermediate frame or the intermediate fitting is used for fixing, the end frame is equipped with the connecting rib. As described above, in carrying out the present invention, including making the end frame and the mounting frame or this and the intermediate frame or intermediate metal fittings of a structure suitable for fixing them, buildings, independent structures, roofs Free end, swinging deflection gap, mounting frame, closing member, fitting groove used as necessary, fitting strip, intermediate frame or intermediate fitting, engaging strip or engaging part, mating strip, elastomer extruded material , the reference width of the oscillating deflection gap, and other specific shapes, structures, materials, dimensions, relationships among them, additions to these, etc., may take various forms as long as they do not contradict the gist of the invention.
