Description

Technical Field

[0001] The present invention relates to an eaves attachment structure.

Background Art

[0002] Conventionally, in the construction field such as office buildings and condominiums, dry exterior walls such as lightweight cellular concrete (hereinafter referred to as "ALC panels") are frequently used as finishing materials for exterior walls, and a construction method of directly attaching a ready-made eaves to the ALC panel is adopted.

[0003] For example, the eaves described in Patent Document 1 and Patent Document 2 propose a construction method of driving anchor bolts into an ALC panel. In addition, the construction method described in Patent Document 3 proposes a construction method of providing a cavity and an insertion port inside an ALC panel, inserting an anchor bolt of an eaves into the insertion port, and then placing concrete to fix the exterior wall and the eaves.

[0004] The eaves attached by these methods handle the external force generated on the eaves by transmitting it to the ALC panel. This is based on the idea of allowing damage to the finishing material during a major earthquake or strong wind in the construction field.

Summary of the Invention

Problems to be Solved by the Invention

[0006] On the other hand, in the construction sector in recent years, there has been a growing demand for business continuity planning (BCP) measures, and for buildings that can be restored in a short period of time in the event of a large-scale disaster. For this reason, there are proposals for buildings that employ structures to prevent damage to finishing materials, thereby shortening the time required for restoration work in the event of a major earthquake or strong winds. Therefore, a structure has been proposed for eaves that transmits external forces generated on the eaves to the building's structure without going through the exterior wall. This structure can prevent damage to the exterior wall.

[0007] Here, we will explain a conventional example of preventing damage to the exterior wall 200, as illustrated in Figure 5. The exterior wall 200 is divided into upper and lower sections in the height direction Z at the installation height of the canopy 100. Between the lower end of the upper exterior wall 210 and the upper end of the lower exterior wall 220, which are created by the division of the exterior wall 200, a structural fixing part 320 fixed to the structural frame 300 is provided. The outdoor-side planar portion 212 of the upper exterior wall 210, the outdoor-side planar portion 222 of the lower exterior wall 220, and the web of the structural fixing part 320 are located in approximately the same position in the depth direction X. Therefore, in the height direction Z, the lower end of the upper exterior wall 210 and the upper end of the lower exterior wall 220 are processed to accommodate the structural fixing part 320. The structural fixing portion 320 is provided with structural fixing connection portions 322 and 323 at its upper and lower ends in the height direction Z. The structural fixing connection portions 322 and 323 are long steel members fixed to the structural frame 300. The structural fixing connection portion 322 is connected to the lower end of the upper outer wall 210, and the structural fixing connection portion 323 is fixed to the upper end of the lower outer wall 220. The gaps between the lower end of the upper outer wall 210 and the structural fixing portion 320, and the gaps between the upper end of the lower outer wall 220 and the structural fixing portion 320 are filled with sealant 500. This configuration provides a construction method in which the structural frame 300, the structural frame fixing part 320, and the canopy 100 are fixed together, and the upper exterior wall 210 and the lower exterior wall 220 do not bear the external force from the canopy 100. However, conventional methods, compared to canopy construction methods that allow for damage to the exterior wall, had the problem of being a difficult construction method requiring extensive division and shortening of the exterior wall 200, as well as extensive waterproofing work continuous in the width direction Y.

[0008] The present invention aims to provide an awning mounting structure that prevents damage to the exterior wall. [Means for solving the problem]

[0009] To achieve the above objectives, the present invention provides the following means. The canopy mounting structure of the present invention is a structure for mounting a canopy to the frame of a building, comprising a frame fixing portion formed on the frame and a canopy fixing portion formed on the canopy, wherein the building comprises an outer wall having an opening between the frame fixing portion and the canopy fixing portion, and the frame fixing portion and the canopy fixing portion are fixed via fasteners, the fasteners being provided so as to penetrate the opening in the outer wall.

[0010] In the above-described mounting structure for the canopy, the fastener comprises a shaft member, the shaft member having an axial length greater than the thickness of the outer wall and a radial length smaller than the opening in the outer wall, and the outer wall may be positioned without interfering with the fastener.

[0011] In the above-described canopy mounting structure, the opening is formed in a position and size such that the gap between the opening and the fastener is greater than the displacement of the opening caused by external force, and the opening may be positioned so as not to interfere with the fastener even if displacement occurs.

[0012] In the above-described mounting structure for the canopy, the shaft member may have male threads formed at one end and the other end, and the frame fixing part and the male thread at one end of the shaft member may be fastened together using a nut, while the canopy fixing part and the male thread at the other end of the shaft member may be fastened together using a nut.

[0013] In the above attachment structure of the eaves, the male threads formed at one end and the other end of the shaft member are formed in different sizes, and the male thread provided on the indoor side may be formed larger than the male thread provided on the outdoor side.

[0014] In the above attachment structure of the eaves, the shaft member is a rod-shaped member having a stepped portion formed at the outdoor end portion, the stepped portion has one or more planes, and the sealing material is filled in the gap generated between the opening portion and the outdoor end portion of the shaft member.

Modes for Carrying Out the Invention

[0017] The attachment structure 1 of an eaves according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 shows an attachment structure 1 of an eaves in an embodiment. This embodiment is an attachment structure 1 that fixes a housing 300 and an eaves 100 so as to sandwich a vertically stretched outer wall 200.

[0018] The exterior wall 200 is a rectangular ALC panel. The exterior wall 200 has an indoor-side flat section 201, an outdoor-side flat section 202, a lateral side section 203, an upper side section 205, and a lower side section 206. In this embodiment, the thickness direction of the exterior wall 200 is defined as the depth direction X. The shorter side of the indoor side planar section 201 and the outdoor side planar section 202 is defined as the width direction Y. The longer side of the indoor side planar section 201 and the outdoor side planar section 202 is defined as the height direction Z.

[0019] The structural frame 300 is a structural element that provides structural support to the building and does not include finishing materials, etc. The structural frame 300 comprises an upper beam 310, a structural frame fixing part 320, and a lower beam 330. The upper beam 310 and the lower beam 330 are long H-shaped steel beams, arranged so that their webs are parallel to the height direction Z. The structural fixing part 320 is a long C-shaped steel beam, arranged so that the web of the C-shaped steel beam is parallel to the height direction Z and the web faces the outside. In the depth direction X and width direction Y, the upper beam 310, the structural fixing part 320, and the lower beam 330 are located at the same position. In the height direction Z, the upper beam 310 is located on the upper level, the lower beam 330 is located on the lower level, and the structural fixing part 320 is located between the upper beam 310 and the lower beam 330.

[0020] The upper beam 310 is provided with an upper connecting portion 311. The upper connecting portion 311 is welded to the upper beam 310. The upper beam 310 is connected to the upper part and upper side portion 205 of the indoor-side planar portion 201 in the height direction Z via the upper connecting portion 311. The lower beam 330 is provided with a lower connecting portion 331. The lower connecting portion 331 is welded to the lower beam 330. The lower beam 330 is connected to the lower part and lower side surface portion 206 of the indoor-side planar portion 201 in the height direction Z via the lower connecting portion 331. The upper connecting portion 311 and the lower connecting portion 331 are elongated members formed by combining two L-shaped angles. Furthermore, the shape and fixing method of the upper connecting portion 311 and the lower connecting portion 331 are not limited as long as they can connect the building structure 300 and the exterior wall 200.

[0021] The exterior wall 200 is positioned so that its indoor-facing planar portion 201 faces inward, and is fixed to the building structure 300 by an upper connecting portion 311 and a lower connecting portion 331. Multiple exterior walls 200 are arranged continuously in the width direction Y such that their lateral side portions 203 coincide.

[0022] The canopy 100 is a prefabricated canopy commonly used in the construction field, such as office buildings and condominiums. (For example, it is a prefabricated canopy proposed in Patent Document 1.) The canopy 100 is equipped with a canopy fixing part 110. The canopy fixing portion 110 is positioned in the same location as the structural fixing portion 320 in the height direction Z, and parallel to the structural fixing portion 320 in the width direction Y. Furthermore, the canopy fixing portion 110 is a long steel member that extends along the entire width of the canopy.

[0023] The indoor side planar section 201 and the outdoor side planar section 202 have through-hole-shaped exterior wall openings 204 formed at the center in the width direction Y and at the lower center in the height direction Z. The exterior wall openings 204 are provided in two adjacent upper and lower levels in the height direction Z. The web of the structural fixing portion 320 has a plurality of through-hole-shaped structural fixing portion holes 321. The plurality of structural fixing portion holes 321 are formed opposite to the plurality of exterior wall openings 204. The canopy fixing portion 110 is provided with a plurality of through-hole-shaped canopy fixing portion holes 111. The plurality of canopy fixing portion holes 111 are formed opposite to a plurality of exterior wall openings 204.

[0024] Figure 2 shows a machined bolt (fastener) 400 in an embodiment. The machined bolt 400 is made of steel. The machined bolt 400 is a rod-shaped member that connects the building structure 300 and the canopy 100. The machined bolt 400 comprises a cylindrical shaft member 401. The shaft member 401 has an indoor-side male thread 402 at its indoor end. The shaft member 401 also has an outdoor-side male thread 403 at its outdoor end.

[0025] The shaft member 401 has an axial length greater than the thickness of the outer wall 200. The shaft member 401 also has a radial length less than the outer wall opening 204. The screw diameter of the indoor-side male thread 402 is larger than the screw diameter of the outdoor-side male thread 403. The shaft member 401 has two stepped portions 404 at its outdoor end. The two stepped portions 404 are formed as a pair of vertically aligned horizontal surfaces in a front view. Multiple machined bolts 400 are provided at positions facing multiple exterior wall openings 204. The machined bolts 400 are inserted through the exterior wall openings 204.

[0026] Figure 3 shows details of the mounting location of the canopy 100 in the embodiment. Figure 3 is a diagram showing a cross-section in the height direction Z at the center of the exterior wall opening 204. The processed bolt 400 is positioned such that the shaft 401 penetrates the exterior wall opening 204, the indoor-side male thread 402 penetrates the structural fixing hole 321, and the outdoor-side male thread 403 penetrates the canopy fixing hole 111. The indoor male thread 402 fastens the structural frame 300 and the processed bolt 400 by using the indoor nut 412 to clamp the structural frame fixing part 320. The outdoor male thread 403 fastens the canopy fixing part 110 by using the outdoor nut 413 to clamp the canopy fixing part 110, thereby fixing the structural frame 300 and the canopy fixing part 110 via the processed bolt 400. In this case, the shaft member 401 has a shaft diameter that is longer than the thickness of the outer wall 200 and smaller than the diameter of the hole in the outer wall opening 204, so it can be installed without interfering with the outer wall 200. The gap between the outdoor end of the shaft member 401, which has a stepped portion 404, and the outer wall opening 204 of the outdoor flat portion 202 is filled with sealant 500.

[0027] The canopy 100 comprises a canopy fixing part 110, a canopy plate 120, an upper fixing part cover 130, a lower fixing part cover 140, a canopy plate fixing bolt 101, and a canopy plate fixing nut 102. The canopy board 120 is a rectangular aluminum plate. The canopy board 120 is positioned so that its longitudinal direction is parallel to the width direction Y. Furthermore, the canopy board 120 is positioned so that the outer end of the canopy board 120 slopes downward at an angle of approximately 2.5 degrees relative to the horizontal plane.

[0028] The canopy fixing section 110 includes a canopy board guide 112 into which the canopy board 120 can be inserted. The canopy board guide 112 has a concave shape into which the indoor end of the canopy board 120 can be inserted. The canopy board 120 has canopy board holes 123 parallel to the thickness direction in the area into which it is inserted into the canopy board guide 112. The canopy board guide 112 also has guide holes 113 at upper and lower positions opposite to the canopy board holes 123.

[0029] The canopy fixing bolts 101 are positioned so that their bolt heads face upward and pass through the guide hole 113 and the canopy hole 123. The canopy fixing bolts 101 are fastened using canopy fixing nuts 102 to fix the canopy fixing portion 110 and the fabricated bolts 400 to the building structure 300 and the canopy 120.

[0030] The canopy fixing portion 110 includes an engaging projection 114 located at one end and an engaging projection 115 located at the other end. The canopy plate guide 112 also includes an engaging projection 116 located at one end and an engaging projection 117 located at the other end.

[0031] The upper fixing part cover 130 is a long aluminum member having a shape that covers the upper half of the canopy fixing part 110 and having the same length as the canopy fixing part 110 in the width direction Y. The upper fixing part cover 130 has an engaging claw 134 at one end that corresponds to the engaging projection 114 and an engaging claw 136 at the other end that corresponds to the engaging projection 116. The upper fixing part cover 130 is fixed to the canopy fixing part 110 by inserting the engaging claw 134 into the recess of the engaging projection 114 and the engaging claw 136 into the recess of the engaging projection 116. The gap created between the upper fixing part cover 130 and the indoor side flat part 201 is filled with sealant 500.

[0032] The lower fixing part cover 140 is a long aluminum member having a shape that covers the lower half of the canopy fixing part 110 and having the same length as the canopy fixing part 110 in the width direction Y. The lower fixing part cover 140 has an engaging claw 145 at one end that corresponds to the engaging projection 115 and an engaging claw 147 at the other end that corresponds to the engaging projection 117. The lower fixing part cover 140 is fixed to the canopy fixing part 110 by inserting the engaging claw 145 into the recess of the engaging projection 115 and the engaging claw 147 into the recess of the engaging projection 117.

[0033] Therefore, the canopy mounting structure 1 of the embodiment is non-contact between the canopy 100 and the exterior wall 200, and fixes the canopy 100 to the building structure 300. As a result, the exterior wall 200 does not bear the external forces generated on the canopy 100.

[0034] Figure 4 shows the state in which rocking occurs in the exterior wall 200. When the exterior wall 200 is subjected to external forces such as earthquakes or strong winds, a swaying displacement (rocking displacement) occurs in the width direction Y.

[0035] Figure 4(a) shows the rocking displacement occurring in the exterior wall 200 of the embodiment. The indoor side planar portion 201 and the outdoor side planar portion 202 are provided with a through-hole-shaped exterior wall opening 204a located in the center in the width direction Y and in the lower center in the height direction Z. In Figure 4(a), the left figure shows the state 51 in which rocking does not occur, and the right figure shows the state 52 in which rocking occurs. With the exterior wall opening 204a in the state 51 in which rocking does not occur as a reference, the exterior wall opening 204a in the state 52 in which rocking occurs has a displacement of 53a.

[0036] Figure 4(b) illustrates rocking displacement occurring in an exterior wall 200 having an exterior wall opening 204 at a different position than in the embodiment. The indoor side planar portion 201 and the outdoor side planar portion 202 are provided with a through-hole-shaped exterior wall opening 204b at one end in the width direction Y and at the lower center in the height direction Z. In Figure 4(b), the left figure shows the state 51 in which rocking does not occur, and the right figure shows the state 52 in which rocking occurs. With the exterior wall opening 204b in the state 51 in which rocking does not occur as a reference, the exterior wall opening 204b in the state 52 in which rocking occurs has a displacement of 53b.

[0037] The exterior wall opening 204a is positioned more favorably closer to the center of the exterior wall 200 than the exterior wall opening 204b in the width direction Y. Therefore, the displacement amount 53a of the exterior wall opening 204a is significantly smaller than the displacement amount 53b of the exterior wall opening 204b. Consequently, because the exterior wall 200 is positioned in the center in the width direction Y, it does not bear the external force generated on the canopy 100 even in the rocking condition 52. The outer wall opening 204 of this embodiment is positioned and shaped such that it remains in a non-contact state with the shaft member 401 even when rocking occurs 52.

[0038] Due to rocking displacement, the amount of displacement 53 occurring in the exterior wall opening 204 decreases in the width direction Y as the position of the exterior wall opening 204 approaches the center of the exterior wall 200. Also, the amount of displacement 53 occurring in the exterior wall opening 204 decreases in the height direction Z as the position of the exterior wall opening 204 approaches the bottom end of the exterior wall 200. However, in the height direction Z, changing the position of the exterior wall opening 204 is accompanied by a change in the installation height of the canopy 100. Therefore, in addition to being located in the center of the exterior wall 200 in the width direction Y, the rocking displacement may be further reduced by positioning the exterior wall opening 204 closer to the lower end of the exterior wall 200 in the height direction Z, within a range where changes in the installation height of the canopy 100 are permitted. Furthermore, if the outer wall opening 204 and the processed bolt 400 can be kept in a non-contact state in the locking condition 52, the position of the outer wall opening 204 in the width direction Y and the height direction Z is not limited.

[0039] Therefore, it has been demonstrated that the canopy mounting structure 1 of the embodiment can provide an efficient and easy construction method while preventing damage to the exterior wall 200.

[0040] As described above, the canopy mounting structure 1 according to this embodiment fixes the building structure 300 and the canopy 100 by sandwiching the exterior wall 200. The building structure 300 comprises an upper beam 310, a building structure fixing part 320, and a lower beam 330. The canopy 100 comprises a canopy fixing part 110. The exterior wall 200 comprises a through-hole-shaped exterior wall opening 204. The processed bolt 400 is arranged such that the shaft member 401 penetrates the exterior wall opening 204, the indoor-side male thread 402 penetrates the building structure fixing part hole 321, and the outdoor-side male thread 403 penetrates the canopy fixing part hole 111. The indoor-side male thread 402 fixes the building structure 300 and the canopy fixing part 110 via the processed bolt 400. As a result, the canopy mounting structure 1 prevents damage to the exterior wall 200. Furthermore, since the canopy mounting structure 1 requires only small-area processing to create an exterior wall opening 204 in the exterior wall 200, it offers significant reductions in construction costs, shorter construction periods, improved construction safety, and high watertightness. In addition, the small-area processing to create the exterior wall opening 204 results in less waste material generation, thus contributing to a reduction in environmental impact.

[0041] Furthermore, in the canopy mounting structure 1 according to this embodiment, the processed bolt 400 comprises a cylindrical shaft member 401. The shaft member 401 has an indoor-side male thread 402 at the indoor-side end. The shaft member 401 also has an outdoor-side male thread 403 at the outdoor-side end. The shaft member 401 has an axial length greater than the thickness of the outer wall 200. The shaft member 401 also has a radial length smaller than the outer wall opening 204. The multiple processed bolts 400 are provided at positions facing the multiple outer wall openings 204. The processed bolts 400 are inserted through the outer wall openings 204. The processed bolts 400 are arranged such that the shaft member 401 penetrates the outer wall opening 204, the indoor-side male thread 402 penetrates the structural fixing hole 321, and the outdoor-side male thread 403 penetrates the canopy fixing hole 111. As a result, the canopy mounting structure 1 can more effectively prevent damage to the exterior wall 200 by transmitting the weight of the canopy 100 and external forces generated on the canopy 100 due to earthquakes or strong winds to the building structure 300 without going through the exterior wall 200.

[0042] Furthermore, in the canopy mounting structure 1 according to this embodiment, the indoor side planar portion 201 and the outdoor side planar portion 202 are provided with a through-hole-shaped outer wall opening 204 located in the center in the width direction Y and in the lower center in the height direction Z. The outer wall 200 is provided with the outer wall opening 204 located near the center of the outer wall 200 so that in the rocking condition 52, the displacement is not hindered by the processed bolt 400 and the outer wall 200 does not bear the external force generated on the canopy 100. As a result, the canopy mounting structure 1 can prevent the processed bolts 400 and the exterior wall opening 204 from interfering with each other, even if rocking occurs in the exterior wall 200 due to an earthquake or strong wind, thereby further preventing damage to the exterior wall 200.

[0043] Furthermore, in the canopy mounting structure 1 according to this embodiment, the processed bolt 400 comprises a cylindrical shaft member 401. The shaft member 401 has an indoor-side male thread 402 at the indoor-side end. The shaft member 401 also has an outdoor-side male thread 403 at the outdoor-side end. The indoor-side male thread 402 fastens with an indoor-side nut 412 so as to sandwich the building structure fixing part 320, thereby fixing the building structure 300 and the processed bolt 400. The outdoor-side male thread 403 fastens with an outdoor-side nut 413 so as to sandwich the canopy fixing part 110, thereby fixing the building structure 300 and the canopy fixing part 110 via the processed bolt 400. As a result, the processed bolt 400, while being a fastener, can possess the strength to bear the weight of the canopy 100 and the external forces acting on it. Furthermore, since the processed bolt 400 reduces the number of parts and processes required for construction, it more effectively results in a significant reduction in construction costs, a shorter construction period, and improved construction safety.

[0044] Furthermore, in the canopy mounting structure 1 according to this embodiment, the shaft member 401 is provided with an outdoor-side male thread 403 at its outdoor-side end. The thread diameter of the indoor-side male thread 402 is formed to be larger than the thread diameter of the outdoor-side male thread 403. As a result, the processed bolt 400 can ensure the bending strength and fixing force of the indoor-side male thread 402, regardless of the type of canopy 100.

[0045] Furthermore, in the canopy mounting structure 1 according to this embodiment, the shaft member 401 is provided with two stepped portions 404 at its outdoor end. The two stepped portions 404 are formed as a pair of horizontal surfaces vertically in a front view. The gap between the outdoor end of the shaft member 401 with the stepped portions 404 and the outer wall opening 204 of the outdoor flat portion 202 is filled with a sealing material 500. As a result, the processed bolt 400, while having a cylindrical shape with high bending strength, has a flat end, making it easy to grip with tools and improving workability. In addition, the canopy mounting structure 1 allows for waterproofing work to be performed over a smaller area, providing more suitable waterproofing.

[0046] Although embodiments of the bag-opening device according to the present invention have been described above, the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the invention.

[0047] In the present invention, the exterior wall 200 does not have to be an ALC panel, nor does it have to be rectangular in shape. For example, the exterior wall 200 may be a square-shaped siding board. In that case, the exterior wall 200 may also be equipped with gypsum board or fire-resistant panel. The exterior wall opening 204 can be provided as a through-hole that penetrates all the components of the exterior wall 200, thereby achieving the same effects as in the embodiment. As a result, the canopy mounting structure 1 of the present invention can be applied to various types of exterior walls 200.

[0048] In the present invention, the exterior wall 200 does not have to be attached to the structural frame 300 in a vertical manner. Furthermore, the exterior wall opening 204 does not have to be located in the center in the width direction Y, as long as it can maintain a non-contact state with the processed bolt 400 in the rocking occurrence state 52. For example, the exterior wall 200 may be a rectangular ALC panel installed horizontally. In that case, the exterior wall 200 needs to have multiple exterior wall openings 204 in the width direction Y. Therefore, the exterior wall 200 cannot have all of its exterior wall openings 204 located at the center of the exterior wall 200 in the width direction Y. Exterior wall openings 204 located away from the center will experience displacements greater than the displacement amount 53a due to rocking, but this can be mitigated by making the shape of the exterior wall openings 204 larger, or by forming the processed bolts 400 from a high-strength material and reducing the diameter of the shaft member 401. As a result, the canopy mounting structure 1 of the present invention can also be applied to buildings such as warehouses where horizontal siding is frequently used.

[0049] In the present invention, the shaft member 401 may be made of a different material as long as it can bear the weight of the canopy 100 and the external forces generated on the canopy 100 due to earthquakes or strong winds, and the shaft member 401, the indoor-side male screw 402, and the outdoor-side male screw 403 may be made of different materials. For example, the machined bolt 400 may be formed from a titanium alloy shaft 401, a steel indoor male thread 402, and a steel outdoor male thread 403. Since the titanium alloy shaft 401 has higher strength compared to the steel shaft 401, it can bear the weight of the canopy 100 and the external forces generated on the canopy 100 due to earthquakes and strong winds with a smaller shaft diameter. Accordingly, the opening 204 in the exterior wall can be made smaller. As a result, the mounting structure 1 of the present invention allows for a smaller area of ​​waterproofing work, thereby achieving more favorable waterproofing.

[0050] In the present invention, the shaft material 401 of the machined bolt 400 does not have to be cylindrical in shape and may be surface-treated. For example, the machined bolt 400 may have a hexagonal shaft 401. This makes it easy to grip the shaft 401 with a tool, even if it does not have a stepped portion 404. Furthermore, the shaft material 401 may be plated on its surface. This improves the corrosion resistance and other properties of the shaft material 401.

[0051] In the present invention, the processed bolts 400 do not need to be arranged in two rows or at equal intervals, as long as they can bear the weight of the canopy 100 and the external forces generated on the canopy 100 due to earthquakes or strong winds. For example, the canopy 100 may be a lightweight canopy that can be connected to the building structure 300 with a single row of processed bolts 400. In that case, the canopy fixing part 110, the exterior wall 200, and the building structure fixing part 320 each have one opening facing each other. Furthermore, the fixing of the building structure 300 and the canopy 100 by multiple processed bolts 400 may be provided at irregular intervals, for example, to avoid interference with other equipment of the building. As a result, the canopy mounting structure 1 of the present invention can provide a form suitable for construction conditions.

[0052] In the present invention, the canopy 100 may be equipped with a suspension member. For example, the canopy 100 is a heavy canopy 100 and may be equipped with a suspension member that connects the upper surface of the canopy board 120 to the building structure 300. The suspension member is equipped with fixing parts at both the indoor and outdoor ends. In this case, the exterior wall 200 is equipped with an exterior wall opening 204 at the fixing position between the building structure 300 and the suspension member. The fabricated bolt 400 is positioned to penetrate the exterior wall opening 204 at the fixing position between the building structure 300 and the suspension member. In addition, the building structure 300 is equipped with an additional building structure fixing part 320 at the fixing position between the building structure 300 and the suspension member. Similar to the embodiment, the building structure fixing part 320 is fixed to the indoor fixing part of the suspension member via the fabricated bolt 400. The outdoor fixing part of the suspension member is fixed to the upper surface of the canopy board 120. Therefore, the suspension members and the canopy 100 are fixed to the structural frame 300 via processed bolts 400, without contact with the exterior wall 200. As a result, the canopy mounting structure 1 of the present invention can also be applied to canopies 100 that require suspension members.

[0053] In this invention, the upper beam 310, the structural frame fixing part 320, and the lower beam 330 are connected to the structural frame 300 and are not limited in shape or material as long as they can bear the weight of the canopy 100 and the external forces generated on the canopy 100 due to earthquakes or strong winds. For example, the upper beam 310, the structural fixing part 320, and the lower beam 330 may all be C-shaped steel, or they may all be H-shaped steel.

[0054] In the present invention, the canopy 100 is not limited in its configuration as long as it has the function of fixing the processed bolt 400 and the canopy fixing part 110, and the function of watertightness to prevent corrosion and water leakage of the processed bolt 400 and the canopy 100. For example, the canopy 100 may be formed by integrally integrating one or all of the following: the canopy fixing part 110, the canopy plate 120, the upper fixing part cover 130, and the lower fixing part cover 140.

[0055] In the present invention, the exterior wall 200 may be included in the structural frame 300. For example, the exterior wall 200 may be a load-bearing wall or seismic wall with bracing. In that case, the exterior wall 200 may be connected to the canopy 100 in the same way as in the embodiment by forming an exterior wall opening 204 at a position that avoids the bracing.
