Description

  The present invention relates to a building structure and a building construction method.

  A typical wooden building structure is a frame structure called a two-by-four (2 × 4) frame structure that uses columns and beams and a frame structure and floor joists without using columns and beams. There are roughly two types of structures (for example, see Patent Document 1 or 2). The shaft structure is characterized in that the load-bearing wall is configured by using columns and beams even if the load-bearing wall is displaced on the upper and lower floors, so that the layout is flexible. The framed wall structure is characterized in that it is easy to ensure construction quality by making the material types uniform, the wall strength is high, and material costs and material processing costs are low.

JP 2003-119918 A JP-A-6-2358

  However, in the conventional frame structure, there are many types of materials such as vertical materials such as columns and studs, foundations and beams, bundles and purlins used for roofs, so special processing and special joints are used for joints and joints of materials. Hardware had to be used, and there was a problem that the material cost and processing cost increased, and the quality of the entire building varied. Even if the walls are staggered, stress concentrates on the base / column / beam / stitched joints and breaks easily. Compared to the wall of the framed wall structure, the stress from the side such as earthquake and wind pressure There was also a problem that it was weak. Further, in the shaft structure, the size of the beam material may be different between the opening and the wall portion, and a joint is formed at the connection portion of the end of the beam material having a different size. There is also a problem that stress tends to concentrate on the joint part, and that strong joint processing and hardware construction are required for the joint, increasing material costs and processing costs. In addition, vertical materials such as pillars and frame materials and horizontal beams such as base beams and purlins are combined and tightened, so special processing such as hozos and alternative hardware and hardware installation are required. There was also the subject that construction cost and material cost increased. In the conventional shaft structure, an attempt has been made to solve difficult joining between a vertical member and a horizontal member by a pre-cut process or a hardware method, but the cost has not been reduced.

  In the conventional framed wall structure, a plurality of plates are combined with nails to form a wall and a floor. A head joint that connects each wall structure on each floor is provided, and a joist is provided on the head joint. There are anti-rollers between them, and the wall structure and the floor / ceiling are nailed from above with nails. In particular, the tight connection between each floor wall and the floor has a head joint that connects each wall structure, so that the nails do not reach the joists directly from the wall frame material. For this reason, it is necessary to nail diagonally from the joist side, and there is a problem in the quality of the tightness as well as weakness in the tightness, and the strength of the head joint and anti-rolling is lower than that of the floor beam of the frame structure. Moreover, since there is no high-strength beam material in each floor and the back of the shed, there is a problem that the strength against the horizontal and vertical load of the floor is low. Moreover, since there is a head connection, the nail does not reach directly from the wall frame material, and the proof strength necessary for tightening cannot be obtained even if the beam material is used, and the tough beam used in the frame structure cannot be used. For this reason, the load-bearing wall of the upper floor must be provided in the load-bearing wall of the lower floor, and the floor plan was restricted. Since the strength of the head connection and the anti-rolling is low, it is not possible to support the vertical load from the floor, and it is necessary to provide a high-powered massa that supports the vertical load of the floor at the upper part of the opening or the like. For this reason, extension and reconstruction are difficult, and the number of construction processes such as mugs and head ties is bulky, and it takes time for construction at the construction site. In addition, in the conventional framed wall structure, the construction at the site is labor-saving by making a panel at the factory, but the creation of the panel creation drawing and the transportation cost are increased, and it has not been possible to reduce the overall cost.

  This invention is made paying attention to such a subject, and provides the building construction method and building construction method which can raise the intensity | strength of both a floor and a wall and can reduce a total construction cost. It is an object.

  In order to achieve the above object, a building structure according to the present invention includes a plurality of wall structures formed by integrating a face material and a frame material, and beam members provided on top of each wall structure. , Characterized by having.

  In the building construction method according to the present invention, after laying the bottom floor board, a plurality of wall structures formed by integrating a face material and a frame material are set up on the upper part of the bottom floor board. A wall is formed, a beam material is provided on the upper part of each wall structure, and an upper floor board or a hut back floor board is laid on the upper part of the beam material.

  The building structure according to the present invention can be constructed by the building construction method according to the present invention. In the building structure according to the present invention, since the beam material is provided at the upper part of each wall structure, the horizontal strength against wind pressure, seismic force, etc. of the upper floor or the floor portion of the hut can be increased. The horizontal strength of this floor is higher than that of the framed wall structure, which is about the same as that of the framed structure using beams. By forming the bearing wall with the wall structure, the strength of the wall can be increased. The strength of the wall at this time is higher than that of the frame structure, and is about the same as that of the frame wall structure using a similar wall structure. Thus, the building structure according to the present invention can increase the strength of both the floor and the wall, and can increase the strength of the entire building.

  Since the beam material is used in the upper part of each wall structure, and the head connection and the magsa which requires strength are not used, the kinds of materials can be reduced. Further, by unifying the dimensions of the beams, the types of materials can be further reduced. For this reason, material costs and material processing costs can be reduced. There are few types of materials, and it is possible to use beams by omitting the magsa provided at the top of the opening in the wall and the head joint that is attached after the wall is formed. Construction time can be shortened, and labor costs can be reduced. Thus, the building structure according to the present invention can reduce the total construction cost. The beam material may be made of a single plate or a laminated beam obtained by bonding a plurality of plates. The pillar laid inside the wall may be made of a single square bar, or may be made of a pillar in which a plurality of plates are bonded together.

  Tightening of the wall structure and a horizontal member such as a base or a beam forming the floor can be easily performed by nailing in the field without using special processing or hardware. The wall and the floor can be integrally formed in a box shape, and the strength can be easily improved. Also, by unifying the dimensions of the beam material, wind stress and seismic force stress can be evenly transmitted to each member without concentrating them and distributed to the ground through the foundation to increase the strength of the entire building. it can.

  The building construction method according to the present invention includes a plurality of bottom floor wall structures formed by integrating a face member and a frame member on an upper portion of the bottom floor plate after laying the bottom floor plate. To form a wall on the lowest floor, and provide a floor beam material on the upper part of each lower wall structure, lay an upper floor board on top of the floor beam material, an upper part of the upper floor board In addition, a plurality of upper floor wall structures formed by integrating the face material and the frame material are raised to form upper floor walls, and ceiling beam members are provided above the upper floor wall structures. A hut back floor board may be laid on the top of the ceiling beam material. In this case, since the floor beam material and the ceiling beam material are provided at the upper part of the wall structure for the lower floor and the wall structure for the upper floor, respectively, the horizontal strength of the floor portion of the upper floor and the floor portion of the shed is improved. Can be increased.

  The building structure according to the present invention has a hut back and a plurality of trusses, and each truss is formed in a ladder shape by attaching a plurality of horizontal members along the width direction inside a rectangular frame. It is preferable that the horizontal members are provided on the back so as to be vertical, and the rafters are supported so as to be perpendicular to the upper side edge of the rectangular frame. Further, in the building construction method according to the present invention, a plurality of trusses formed in a ladder shape by attaching a plurality of horizontal members along the width direction inside the rectangular frame to the upper part of the shack back floor board, respectively. It is preferable to install the rafter so that the horizontal member is vertical and to extend perpendicularly to the upper side edge of each truss. In the case of having this truss, the rafters are supported by the truss formed in a ladder shape, so that the strength of the cabin set can be increased. Compared to a conventional shed structure that requires several types of materials to be combined to create a joint such as sculpting, it is easy and free to assemble on site by cutting and nailing one type of material. Therefore, the material management cost and construction labor cost can be reduced. Each truss preferably comprises a Feelendale truss.

The truss 20 has the largest width at the position of the ridge of the roof of the building, with a predetermined interval along the slope of the roof of the building, and from the ridge to the eave in descending order. Is arranged. The truss 20 is arranged at a predetermined interval according to the shape of the roof, the gradient from the outer periphery of the building, and the member cross-sectional dimensions of the rafters 21.

  As shown in FIGS. 1, 5, and 6, the rafters 21 are installed on the upper side edges of the trusses 20 and the ceiling beam members 18 so as to extend perpendicular to the trusses 20. It is fixed and fixed to the ceiling beam member 18 by the joint fitting 42. The rafters 21 are provided so as to incline downward from the purlins toward the eaves. In the building structure 10, a roof plate can be formed by constructing a base plate on a rafter 21 and attaching a color iron plate or tile as a roof finishing material.

  The building structure 10 can be constructed by the building construction method according to the embodiment of the present invention. As shown in FIG. 7, first, the base 12 is installed on the foundation 11, and the lowest floor board 13 is laid on the base 12 to form the first floor, which is the lowest floor. After laying the lowermost floor board 13, each lower floor wall structure 14 is raised above the lowermost floor board 13 to form the outer and inner walls of the first floor, which is the lowest floor. A floor beam material 15 is directly provided on the upper part of each lower floor wall structure 14, and an upper floor plate 16 is laid on the upper part of the floor beam material 15 to form a second-floor floor. Each upper floor wall structure 17 is raised above the upper floor board 16 to form the outer and inner walls of the second floor, which is the upper floor. A ceiling beam member 18 is provided on the upper part of each upper floor wall structure 17, and a hut back floor board 19 is laid on the upper part of the ceiling beam member 18. Each truss 20 is provided on the upper part of the shed back floor plate 19 so that each horizontal member is vertical, and a rafter 21 is installed on the upper side edge of each truss 20 so as to extend perpendicularly to each truss 20.

  In this way, in the building structure 10, the floor beam material 15 and the ceiling beam material 18 are provided above the lower floor wall structure 14 and the upper floor wall structure 17. The horizontal strength of the floor of the hut against wind pressure, seismic force, etc. can be increased. The horizontal strength of this floor is higher than that of the framed wall structure, which is about the same as that of the framed structure using beams. Since the bearing wall is formed by the wall structure 14 for the lowest floor and the wall structure 17 for the upper floor, the strength of the wall can be increased. The strength of the wall at this time is higher than that of the frame structure, and is about the same as that of the frame wall structure using a similar wall structure. Thus, the building structure 10 can increase the strength of both the floor and the wall, and can increase the strength of the entire building. In addition, since the rafters 21 are supported by the truss 20 formed in a ladder shape, the strength of the cabin can be increased. Compared to a conventional shed structure that requires several types of materials to be combined to create a joint such as sculpting, it is easy and free to assemble on site by cutting and nailing one type of material. Therefore, the material management cost and construction labor cost can be reduced.

  Since the floor beam material 15 and the ceiling beam material 18 are used above the lower floor wall structure 14 and the upper floor wall structure 17 and no mass connection is required for connecting the head and strength, the number of materials is reduced. be able to. Further, by unifying the dimensions of the floor beam material 15 and the ceiling beam material 18, the types of materials can be further reduced. For this reason, material costs, inventory management, and material processing costs can be reduced. The use of floor beams 15 and ceiling beams 18 can be made possible by eliminating the use of a small number of materials, such as the masses provided at the top of the openings in the walls and the head joints that are attached after the walls are formed. The construction time at the construction site can be shortened by increasing the labor cost and the labor cost can be reduced. In a specific example, the cross-sectional size of the square bar used is 90 mm × 90 mm used for the base 12 or the like, the pillar 32, the vertical frame member 33, the upper frame member 34, the lower frame member 35, the rafter 21 or the like. There are four types: 38 mm × 90 mm used, 90 mm × 270 mm used for floor beam material 15, and 38 mm × 184 mm used for ceiling beam material 18. Even when the lengths are different, there are five types of square members, which is less than about 15 types of conventional shaft assembly structures and about 10 types of conventional framed wall structures. As described above, the building structure 10 can balance the factory production cost and the on-site production cost, and can greatly reduce the number of joints compared to the conventional frame structure. On the other hand, on-site production labor costs can be reduced, and the total construction cost can be reduced.

  The building structure 10 is specially constructed by tightly bonding the bottom floor wall structure 14 and the upper floor wall structure 17 to horizontal members such as the base 12, the floor beam material 15, and the ceiling beam material 18 that form the floor. It can be easily performed by nailing in the field without using any special processing or hardware. Since the wall and the floor can be integrally formed in a box shape, the strength is high. In addition, by unifying the dimensions of the floor beam material 15 and the ceiling beam material 18, the wind pressure and the stress of the seismic force are evenly transmitted to each member without being concentrated on a part, and distributed to the ground through the foundation. The overall strength can be increased.

  Since the building structure 10 can use the floor beam material 15 and the ceiling beam material 18 by omitting the head connection, the horizontal strength of the floor can be increased and the flexural rigidity with respect to the vertical load can be secured. Further, the tough floor beam material 15 can maintain the structural strength even when the load bearing wall is displaced between the upper and lower floors, and can increase the degree of freedom of the floor plan as compared with the conventional framed wall structure. It should be noted that the head joints and anti-rollers used in the conventional framed wall structure are not taken into account in the structural calculation because of their low strength. On the other hand, since the building structure 10 uses the floor beam material 15 and the ceiling beam material 18 having high strength without using the head connection and the anti-rolling, these can be taken into the structural calculation.

  In conventional framed wall structures, floor flexure and horizontal strength are low, so it is necessary to use a material with strength that can support the vertical load transmitted from the floor as a massa used at the top of the opening of the wall structure. was there. On the other hand, in the building structure 10, since the floor beam material 15 and the ceiling beam material 18 having sufficient strength against the vertical load and deflection of the floor are used, the bottom floor wall structure 14 and the upper floor wall structure are used. The magsa 36 used in the upper part of the opening of the body 17 does not require proof stress, and a thin square member can be used.

  As described above, the building structure 10 has a structure in which the disadvantages of the conventional frame structure and the frame wall structure are improved and the advantages of the conventional frame structure and the frame wall structure are combined.
