Description

[Technical field]

[0001] The present invention relates to a porch provided at the entrance of a building. [Background technology]

[0002] A porch is a space provided at the entrance of a house or building that is used when users enter and exit the building. Some porches have a roof or ceiling, which protects users from wind, rain, and sunlight, making it more comfortable to enter and exit the building.

[0003] In addition, entrance porches come in various types, such as a gate-shaped porch that is installed integrally with the veranda at the front of the building, as in Patent Document 1, and a porch that protrudes from the foundation to make construction easier, as in Patent Document 2.

[0004] [Patent Document 1] JP 2000-273945 A [Patent Document 2] Japanese Patent Application Publication No. 10-331252 Summary of the Invention [Problem to be solved by the invention]

[0005] Since the entrance porch is located at the front of the building and has a large impact on the exterior appearance, it is preferable to make it compatible with functionality, including durability, and design. For example, if the entrance porch is located off the ground, it is possible to prevent rainwater, sand, and insects from entering through the entrance, while also improving the design.

[0006] In view of the above problems, the present invention aims to provide a front door porch that combines functionality and design. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides an entrance porch provided in a building having a foundation and a wall on which an entrance door is provided, wherein a porch portion is provided below the entrance door and extends from the foundation, and at least a portion of the porch portion is spaced apart from the ground. This structure reduces the area where the foundation for the porch needs to be poured separately from the foundation of the building, and allows for a wider range of design options for the front of the building. Also, by having the porch part set up "against" the foundation, it is possible to prevent sand, insects, etc. from entering through the front door, improving functionality.

[0008] Preferably, the pouch portion is cantilevered across its entire width perpendicular to its extension direction and parallel to the ground. This improves the performance of the "turn-up" and allows for a design that gives the pouch a floating feel.

[0009] Preferably, the pouch portion has sleeve walls protruding upward from both ends, and the sleeve walls are connected to the wall surface. This makes it possible to prevent wind and rain from entering through the sides of the pouch, improving functionality.

[0010] Preferably, the upper end of the sleeve wall is provided with a eaves section, which prevents wind and rain from entering through the top of the porch, improving functionality, and forming a gate-shaped frame structure that improves durability and design.

[0011] Preferably, the building has a roof and the eaves extend from the roof. This makes it possible to integrate the structure with the building and simplify the structure, thereby improving the durability of the eaves and entrance porch.

[0012] Preferably, the sleeve wall portion includes a sleeve wall column therein, the eaves portion includes an eaves beam therein, and the sleeve wall column and the eaves beam are connected to each other. This stabilizes the structure inside the entrance porch and improves durability.

[0013] In order to achieve the above-mentioned object, the present invention provides a building comprising a foundation, a wall on which a front door is provided, and a front door porch, the front door porch having a porch portion extending from the foundation below the front door and at least a portion of which is spaced apart from the ground. This allows us to provide buildings that are both functional and stylish. Effect of the Invention

[0014] The entrance porch of the present invention, which solves the above-mentioned problems, and a building including an entrance porch, can achieve both functionality and design. [Brief description of the drawings]

[0016] Hereinafter, the entrance porch 2 according to each embodiment of the present invention will be described with reference to the drawings. The description will be made in detail in the order of the configuration of the embodiment, the method of implementing the embodiment, and other examples. The following embodiments are merely examples of the present invention, and the present invention is not limited to the following embodiments. In addition, the word "substantially" in the application documents is a concept that includes shapes that follow with chamfering or rounding, and elements that make up the shape that have been deformed or changed in length within a range that does not impede the purpose of the configuration.

[0017] First Embodiment The present invention is an entrance porch 2 provided in a building 1, as shown in Figures 1 and 2. The entrance porch 2 is provided in a shape spaced apart from the ground G and protruding from the front of the building 1, and has a space inside where a user can enter. Note that Figure 1(a) is a front view of the present invention, and Figure 1(b) is a right side view of the present invention.

[0018] The building 1 has at least a foundation 11, a wall surface 12 which is the front wall of the building 1 built on the foundation 11, a roof 13 built on the upper surface, and a living space floor 14. A front door 15 which is an entrance to the building 1 is provided on the wall surface 12, and the building is a two-story detached house which is further provided with a window 16.

[0019] The entrance porch 2 is connected to the wall surface 12 of the building 1 and has a porch section 21 extending from the foundation 11 on which the user stands, sleeve wall sections 22 which are walls that protrude upward from both side ends of the porch section 21 and cast a shadow on the porch section 21, and eaves section 23 which is a eave that spans the upper end of the sleeve wall sections 22 and casts a shadow on the porch section 21, and these components are connected to form a structure that includes a rectangle when viewed from the front.

[0020] As shown in Fig. 3(a), the foundation 11 is a material provided as the foundation of the building 1. The foundation 11 has a horizontal foundation body 110 poured from the ground to the ground surface, a rising part 111 rising from the top surface of the foundation body 110 and supporting the base 142 with its top surface, and a footing part 112 supporting the foundation body 110 from below in the ground. In addition, underground beams 113 are arranged at predetermined positions inside the foundation 11 to increase durability, and a foundation drain 114 is provided on the top surface of the rising part 111 to prevent liquid from entering the foundation 11. In addition, concrete or broken granite is laid under the bottom of the foundation 11 to reinforce the ground.

[0021] The foundation body 110 is a so-called slab foundation, which is a flat plate-like material that supports the entire underside of the building 1. On the top surface side of the foundation body 110, a rising portion 111 is provided that protrudes upward so as to surround the periphery of the foundation body 110, and a footing portion 112 that extends horizontally outward of the building 1 is provided below the foundation body 110. This reinforces the building 1 so that it does not sink even if an entrance porch 2 is provided. On the other hand, the foundation body 110 may be a so-called slab foundation.

[0022] The rising portion 111 is formed integrally with the foundation body 110 and the pouch portion 21. The foundation body 110 and the rising portion 111 are cast separately, but it is preferable that the rising portion 111 and the pouch portion 21 are cast simultaneously to increase the mounting strength of the pouch portion 21.

[0023] The underground beams 113 are so-called reinforcing bars, and are provided horizontally throughout the interior of the foundation body 110 to reinforce the structure. The underground beams 113 form a truss including a portion horizontally disposed below the ground surface G, a portion extending horizontally directly below the rising portion 111, a portion extending vertically, and an inclined portion connecting the respective portions, thereby increasing the durability of the foundation 11 and suppressing the destruction of the foundation 11 due to the load. The truss structure may also be extended to the footing portion 112 at the bottom of the foundation body 110 to increase its strength.

[0024] The foundation body 110 is provided on the front side of the building 1 so as to extend to the outside of the building 1. At this time, the rising portion 111 protrudes upward inside the edge of the foundation body 110. The trusses of the footing portion 112 and the underground beams 113 are provided near the edge of the foundation body 110 and reinforce the porch portion 21 at the top.

[0025] FIG. 4 is a plan view of the area around the entrance porch 2 taken along the line AA in FIG. 1, and FIG. 5 is a plan view of the area around the entrance porch taken along the line BB. The wall surface 12 is the wall on the front side of the building 1, and has an exterior wall 121 provided on the exterior side of the building 1, and an interior wall 122 provided on the interior side. A plurality of wall columns 123 such as through columns, pipe columns, and partition columns are erected between the exterior wall 121 and the interior wall 122 to support the structure of the building 1, and the insulation material I is filled in to increase the comfort of the living environment.

[0026] The roof 13 comprises a roof body 130, a truss 132 which is a base for supporting the structure of the roof body 130 from below, and a roof beam 131 which spans the wall columns 123 and supports the truss 132 from below.

[0027] The roof body 130 includes, but is not limited to, sheathing boards that face inward and cover the truss 132, and materials that cover the outside of the roof, such as slate, galvalume steel sheeting, roof tiles, and galvanized iron, that face outward. The truss 132 also includes materials such as a ridgepole, purlins, rafters, and rafters.

[0028] The floor 14 is a horizontal member installed inside the building 1, and has a floor body 140 on which a user stands. The floor body 140 is installed in the air relative to the foundation 11 via a floor beam 141 installed on the foundation body 110, and a base 142 installed on the floor beam 141 and the rising portion 111. A second floor floor 143 installed on the second floor is supported by beams 144. A ceiling 145 is installed inside the building 1 so as to face the floor body 140.

[0029] The top surface of the floor body 140 is provided at a position higher than the top surface of the porch portion 21, thereby preventing rainwater, sand, and insects from entering above the floor body 140.

[0030] The base 142 is disposed on the top surface of the rising portion 111, and supports the building 1 independently of the porch portion 21. This prevents the porch portion 21 from being broken by the load of the building 1 being applied thereto.

[0031] The entrance door 15 is a hinged door that can be opened and closed in a direction away from the sleeve wall 22, preventing hands from interfering with the sleeve wall 22 when the entrance door 15 is opened. The entrance door 15 is also provided directly above the rising portion 111 in a portion of the wall surface 12, preventing a load from being applied to the porch portion 21.

[0032] The entrance door 15 is located away from the center of the two sleeve walls 22, and in this embodiment, is provided in a position adjacent to the sleeve wall 22. This improves the design of the wall surface 12 and the freedom of layout. For example, it is possible to arrange a window 16 with a size approximately equal to (or larger than) half the distance between the sleeve walls 22, improving natural lighting even when the sleeve walls 22 are provided.

[0033] The window 16 is a transparent plate material provided on the wall surface 12, and is disposed between the opposing sleeve wall portions 22, and in this embodiment, is provided adjacent to the sleeve wall portion 22. By positioning the window 16 in a place that is likely to be in the shadow of the sleeve wall portion 22 in this way, it becomes difficult to see inside the window 16, and privacy can be maintained.

[0034] Porch section 21 is a member extending on the outer surface of foundation 11, and is made of the same material as foundation 11. Porch section 21 has pouch main body 210 which is a slab on which a user stands, standing section 213 standing from the top surface of pouch main body 210, and pouch drain 214 which is provided on the top surface of standing section 213 and prevents water from entering gaps in pouch section 21. In addition, pouch reinforcing bars 215 are arranged inside pouch main body 210 to increase its strength.

[0035] The pouch body 210 is a slab extending laterally from the rising portion 111, with a portion of its bottom surface spaced apart from the ground G to form a cantilever beam, and its width is 30% to 90% of the width of the wall surface 12 on which the porch portion 21 is provided, its protruding length is 20 cm to 120 cm, and its thickness is 10 cm to 40 cm.

[0036] Pouch body 210 extends from the side surface of rising portion 111, and a part of the bottom surface is connected to base body 110. A part of pouch body 210 extends and protrudes outward beyond the side end surface of base body 110, and this part is separated from the ground G. This part is cantilever-supported by the part of pouch body 210 to which it is connected, across the entire width direction of pouch body 210 (direction perpendicular to the extending direction and parallel to the ground).

[0037] Moreover, the porch body 210 is cast onto the foundation body 110 at the same time as the rising portion 111. In the embodiment, about 2 / 3 of the porch body 210 is provided on the foundation body 110, and the remaining about 1 / 3 is spaced apart from the ground G. By providing the foundation 11 as described above, the stability and earthquake resistance of the porch portion 21 or the entrance porch 2 can be further improved.

[0038] The top surface of pouch body 210 is provided below the top surface of rising portion 111, so that the height of pouch body 210 is lower than that of foundation 11, making it easy to ascend and descend steps.

[0039] In addition, the bottom surface of pouch body 210 is provided at a distance from ground G, and is further provided on the same plane as or above the joint surface of rising portion 111, thereby preventing water from splashing on the joint surface. In addition, since the bottom surface is separated from ground G, it is possible to prevent pouch body 210 from corroding from the bottom surface.

[0040] The top and side surfaces of the porch body 210 have a construction section 211 where waterproofing is performed, for example, by lath mortar construction. The construction section 211 is slightly inclined (exaggerated in FIG. 4) toward the outside of the building 1, improving the drainage of the porch section 21.

[0041] In addition, an L-shaped water drain 212 is provided at the corner between the side and bottom of the pouch body 210 to prevent corrosion caused by water running down to the foundation 11.

[0042] Upright portions 213 are rectangular parallelepiped portions standing on both ends of pouch body 210 in the width direction, and their top surfaces are at approximately the same height as the top surface of rising portion 111. Upright portions 213 extend from both ends of rising portion 111, and their width is approximately the same as rising portion 111, and their extending length is the same as pouch body 210, and together with pouch body 210 they form a U-shape when viewed from the front.

[0043] The porch drip-line 214 is provided along the edge of the top surface of the standing portion 213, and prevents water that has trickled down from the sleeve wall portion 22 from directly hitting the porch portion 21. The foundation drip-line 114 is also provided at the top end of the rising portion 111 between the two standing portions 213, and the porch drip-line 214 is provided continuously from the foundation drip-line 114 horizontally to surround the top end of the foundation 11, improving the appearance and increasing the efficiency of the drip-line.

[0044] 3, porch reinforcing bar 215 is a metal reinforcing material that is arranged when pouring porch body 210, and improves the earthquake resistance of porch body 210, which is made of concrete. Note that porch reinforcing bar 215 may be a reinforcing bar having a surface formed by combining metal bars in a cross or diamond shape, or a simple metal plate may be used.

[0045] Porch reinforcing bar 215 is disposed horizontally so as to span substantially the entire porch body 210, with at least a portion of it being included inside rising portion 111. This results in porch reinforcing bar 215 being sandwiched between the body of building 1 and foundation body 110, improving durability even if a portion of porch body 210 is a cantilever beam.

[0046] In addition, porch reinforcing bar 215 and underground beam 113 may be connected to further improve ease of construction and stability. For example, underground beam 113 may pass through rising portion 111 and bend further toward the portion where porch main body 210 is provided, and the horizontal portion at the end of the bend may be porch reinforcing bar 215.

[0047] On the other hand, as shown in Fig. 3(b), a rising portion 111 may be provided on the edge of the foundation body 110, and the base 142 may be supported on the rising portion 111. In this case, the pouch body 210 is provided as a cantilever beam that extends from the rising portion 111 to the side as a whole. This simplifies the shape of the foundation 11 to increase its strength, and increases the size of the return portion of the pouch portion 21, improving functionality and design.

[0048] 6, the sleeve wall portion 22 has a sleeve wall main body 220 corresponding to the outer wall, a sleeve wall base 221 connected to the standing portion 213, a sleeve wall column 222 standing on the sleeve wall base 221 inside the sleeve wall main body 220, and a sleeve wall beam 223 connecting the sleeve wall column 222 and the wall column 123. The sleeve wall portion 22 is provided at a position adjacent to the wall column 123, thereby increasing its durability.

[0049] The sleeve wall main body 220 is a wall-shaped member erected so as to surround the outer edge of the erected portion 213, and is the same as the outer wall 121, but is made of a material of a different color, thereby improving design and durability. In addition, a moisture-proof and breathable sheet is attached to the inner peripheral surface of the sleeve wall main body 220 to prevent the wood inside from rotting.

[0050] The sleeve wall base 221 is a columnar member that is disposed lying on the top surface of the standing portion 213 and is fixed to the standing portion 213 with anchor bolts. A gap is provided between the side end face of the standing portion 213 and the sleeve wall base 221, and the sleeve wall main body 220 is disposed in this gap. In addition, a mortise H is provided on the upper surface of the end of the sleeve wall base 221 opposite the building 1, so that it can be connected to the sleeve wall column 222. The sleeve wall base 221 may be connected to the foundation 142.

[0051] The sleeve wall column 222 is a column erected parallel to the wall column 123, and is at approximately the same height as or slightly lower than the sleeve wall main body 220. The lower end of the sleeve wall column 222 connects to a mortise H provided in the sleeve wall base 221, and a mortise H is provided on the adjacent side of the upper end for connecting to the sleeve wall beam 223 or the eaves beam 231 described later. The sleeve wall column 222 increases the stability including the eaves portion 23.

[0052] The sleeve wall beam 223 is a member that horizontally connects the upper end of the sleeve wall column 222 and the wall column 123, and improves the strength of the sleeve wall section 22. The sleeve wall beam 223 has a top surface that is flush with the upper end of the sleeve wall column 222, and at least a portion of it is provided on a horizontal plane that includes the roof beam 131, thereby improving the strength of the entrance porch 2.

[0053] The inside of the sleeve wall portion 22 is hollow except for the above-mentioned components, thereby making it lighter and increasing its strength by reducing the burden on the pouch portion 21 and the pillar materials. On the other hand, a reinforcing portion may be provided inside the sleeve wall portion 22 to maintain the connection of the sleeve wall main body 220. For example, a structural plate connected to the sleeve wall column 222 in the same manner as in a normal wall may be erected, and a furring strip provided on the structural plate may fix the sleeve wall main body 220.

[0054] Here, the outer wall 121 is provided continuously with the sleeve wall main body 220. That is, the end surface of the outer wall 121 and the end surface of the sleeve wall main body 220 are in contact with and connected to each other at a position adjacent to the wall column 123. It is preferable that the gap between both components is made watertight with a caulking material.

[0055] On the other hand, the outer wall 121 may be provided over the entire wall surface 12, and the sleeve wall base 221 and the sleeve wall beam 223 may be cut out in the outer wall 121 only at the portions corresponding to the connection positions, and the end of the sleeve wall main body 220 may be connected to the surface of the outer wall 121.

[0056] The eaves portion 23 protrudes from the wall surface 12 and comprises an eaves main body 230 whose top surface receives rain and sunlight, an eaves beam 231 that connects the ends of the eaves main body 230, an eaves truss 232 that supports the eaves main body 230 from below and transfers the load to the eaves beam 231, an eaves soffit 233 provided on the underside, a wide lattice 234 provided at the tip of the eaves main body 230, and an eaves drip edge 235 that prevents water from dripping onto the eaves soffit 233.

[0057] The eaves portion 23 is provided at a position substantially the same as or slightly higher than the ceiling 145 of at least the first or second floor, and functions as a sunshade and rain shield.

[0058] The eaves body 230 is made of the same material as the roof body 130, and is provided with a slight downward inclination in the direction away from the building 1. This achieves a rain shelter function.

[0059] The eaves beam 231 is a beam that spans the upper ends of the two sleeve wall columns 222, and its upper surface supports the tip of the eaves main body 230. The sleeve wall columns 222 and the eaves beam 231 form a rigid gate-shaped structural material, increasing stability, and when combined with the porch main body 210, a rigid gate-shaped structural material is formed, thereby increasing the strength of the structure. Furthermore, these members form a rigid frame structure together with the wall columns 123 and the sleeve wall beam 223, further increasing the structural strength of the entrance porch 2.

[0060] The eaves truss 232 is a member that transfers the load of the eaves main body 230 to the eaves beams 231 and sleeve wall beams 223, and enables the load to be distributed by members with beams and notches that match each beam.

[0061] The eaves 233 is a component installed on the underside of the eaves portion 23 from the wall surface 12 to the end, and is made of the same material as the sleeve wall main body 220 to improve its appearance.

[0062] Wide lattice beam 234 connects to eaves truss 232 at the side end of eaves beam 231, preventing water from entering inside eaves section 23. In addition, an L-shaped eaves drip edge 235 is provided from the side to the bottom of wide lattice beam 234, preventing water from entering from here. The end face of wide lattice beam 234 is provided at least further outward from building 1 than the end face of porch body 210, making it difficult for rain to drip onto porch body 210.

[0063] In addition, an entrance approach 3, which is a stone slab and stairs, is provided in front of the entrance porch 2. The entrance approach 3 is adjacent to the porch main body 210, so that a user is less likely to slip his / her foot in the gap between the porch main body 210 and the entrance approach 3 and fall. In addition, since the entrance porch 2 is integrated with the building 1, the design freedom of the entrance approach 3 is improved.

[0064] The method of using the present invention will be described in detail below. The present invention is implemented by a user who uses the entrance porch 2. The implementation method described below is an example, and the implementation method is not limited to this, and the order of the implementation may be changed.

[0065] The user stands on the entrance approach 3, then stands on the entrance porch 2 to open the entrance door 15. At this time, because the entrance porch 2 as a whole protrudes in a gate shape, the user is less exposed to wind and rain from the top and sides, reducing discomfort when making preparations before entering the entrance door 15. Also, the entrance approach 3 is lowered by the amount that the entrance porch 2 is spaced apart from the ground G, making it more comfortable to use.

[0066] Second Embodiment The entrance porch 2 according to the second embodiment of the present invention will be described in detail below with reference to Figures 7 and 8. The same parts as those in the first embodiment will be designated by the same reference numerals and will not be described. Figure 7(a) is a front view of the present invention, and Figure 7(b) is a right side view of the present invention. Figure 8 is a plan view of the entrance porch 2 and its surroundings in the CC cross section of Figure 7.

[0067] 7 and 8, the building 1 has a foundation 11, walls 12, a roof 13, and a floor 14. The wall 12 is provided with an entrance door 15, and is a detached house that is further provided with a window 16. The entrance porch 2 has a porch portion 21 extending from the foundation 11, a sleeve wall portion 22, and an eaves portion 23 that serves as an eaves, and these members are connected to form a structure that includes a rectangle when viewed from the front.

[0068] Roof 13 comprises a roof body 130, a truss 132, and a roof beam 131. In this embodiment, roof 13 is inclined from the front to the back and protrudes outward beyond wall surface 12, with the protruding portion forming eaves portion 23. By configuring roof 13 in this manner, the load on entrance porch 2 can be reduced.

[0069] The truss 132 has rafters 133 that abut against and support the underside of the roof body 130, and the rafters 133 are supported by other members of the truss 132 and by wall pillars 123, and are provided so as to protrude from the wall surface 12. The portion of the rafter 133 that protrudes from the wall surface 12 serves as a sleeve wall beam 223 and is located inside the sleeve wall section 22 to support the eaves section 23.

[0070] The entrance door 15 is a hinged door, and is disposed so as to contact the sleeve wall portion 22 when opened. This allows a large space for the user to get ready when the entrance door 15 is open. The entrance door 15 is also disposed on the outside of the wall surface 12 adjacent to the sleeve wall portion 22.

[0071] 7(a), the sleeve walls 22 are provided closer to the center of the building 1 than in the first embodiment, and the area between the two sleeve walls 22 occupies approximately 1 / 3 of the width of the entire building. In this way, by arranging the sleeve walls 22 to support the extending roof 13, the stability and design of the entire building can be improved.

[0072] The eaves portion 23 includes an eaves main body 230, which is a part extending from the roof main body 130, an eaves beam 231 that spans between the sleeve wall columns 222 or the rafters 133, an eaves truss 232 (not shown), an eaves soffit 233, a wide rafter 234 provided at the end of the rafter 133, and an eaves drip edge 235.

[0073] By providing the eaves portion 23 extending from the roof 13, the design and stability of the entrance porch 2 can be further improved.

[0074] Third Embodiment The entrance porch 2 according to the second embodiment of the present invention will be described in detail below with reference to Fig. 9. The same parts as those in the second embodiment will be designated by the same reference numerals and will not be described. Fig. 9(a) is a front view of the present invention, and Fig. 9(b) is a left side view of the present invention.

[0075] As shown in Fig. 9, building 1 has foundation 11, walls 12, roof 13, and floor 14. It is a detached house in which wall 12 is provided with entrance door 15 and further with window 16. In addition, entrance porch 2 has porch portion 21 extending from foundation 11, sleeve wall portion 22, and eaves portion 23 which serves as eaves, and these members are connected to form a structure including a rectangle when viewed from the front.

[0076] 9(a), the wall surface 12 has a first wall surface 12A having an entrance door 15, and a second wall surface 12B continuing from the first wall surface 12A. Both the first wall surface 12A and the second wall surface 12B are rectangular, and the height of the first wall surface 12A is higher than that of the second wall surface 12B.

[0077] In addition, the building 1 has a first building 1A provided behind the first wall 12A and a second building 1B provided behind the second wall 12B, and the second floor portion of the first building 1A is configured so as to have a shorter depth than the second building 1B.

[0078] In the embodiment, the side surface of the building 1 is entirely covered by a plate-shaped side wall 17. That is, the side wall 17 has a first side wall 171 covering the entire side surface of the first building 1A, a second side wall 172 covering the entire side surface of the second building 1B, and a boundary side wall 173 covering the entire second floor portion of the first building 1A at the boundary between the first building 1A and the second building 1B. Here, the first side wall 171 is a rectangular plate with a region cut out that does not overlap with the boundary side wall 173 in a side view, and the second side wall 172 and the boundary side wall 173 are also rectangular plates.

[0079] The roof 13 is provided between the first side wall 171 and the boundary side wall 173 in the second floor portion of the first building 1A, between the second side wall 172 and the boundary side wall 173 in the area adjacent to the boundary side wall 173 of the second building 1B, and between the first side wall 171 and the second side wall 172 in the other areas. The components are the same as those in the second embodiment, so the description will be omitted. By providing the side walls 17 and roof 13 in this manner, it is possible to achieve both an angular design when viewed from the front and the drainage of the roof 13. The roof 13 may be a flat roof with an eave portion 23 extending from the top surface.

[0080] The porch section 21 is provided over the entire area from one end to the other end of the first building 1A, and the sleeve wall section 22 is erected so that its end face is on the same plane as the end faces of the first side wall 171 and the boundary side wall 173. The eaves section 23 is also provided so that the height of its end is approximately the same as the height of the first side wall 171 and the boundary side wall 173, and the entrance porch 2 is formed to cover the edge of the first building 1A. This makes it easier to design the position of the wall column 123 and the position of the sleeve wall section 22 to match, improving durability.

[0081] The present invention may be applied to panel construction, RC construction, and SRC construction, and a person skilled in the art may extract modifications of the present invention or technical matters of multiple embodiments to create other embodiments. [Explanation of symbols]
