Description

  The present invention relates to a plan for a medium- and small-sized building having a room with different functions when viewed in plan, and is divided into different areas according to applications and functions. For each floor plan of an extension building to be expanded adjacent to the existing building, the span allocation according to the application and function is performed independently for each area, other areas where the span allocation is determined in relation to the existing building, and other It belongs to the technical field of the frame construction method, which divides the area, performs appropriate span allocation for each area independently, and constructs a spanned building frame suitable for each application, function, etc.

  Conventionally, the frame format in the plan plan of the column / beam frame building is such that, for example, as shown in FIG. 6, grid division common to the X and Y biaxial directions is naturally performed. Reference numeral 1 in the figure indicates a pillar, and 2 indicates a beam. Even if the building plane is divided into an area A and a common area B that are different in usage and function, and a corridor C is provided between both areas, the span m, n that is usually determined by the room plan It was common to divide the grid. By the way, the reason why the grid division common to the X and Y biaxial directions is taken as a matter of course is to emphasize the straightness of the core of the pillar and beam, and to make waste and unreasonable in the flow, transmission and balance of force. This is because priority is given to mechanical considerations so as not to come, and in the construction, if the reinforcing bars are arranged diagonally, the accommodation is poor and the workability is difficult.

  As a result, the shared part naturally limited the plan of the floor plan, and the shared part where the span allocation was inappropriate had no choice but to accept the inconvenience, inconvenience and disadvantage of the use and function. In addition, the corridor portion C is usually an arrangement route for equipment piping and the like. However, since the beam 2 crosses the route, even if it is a beam penetration type, it takes a lot of construction work even if it passes under the beam. There was an inconvenience that adversely affects the floor height.

  In Patent Document 1 below, as a rational connection method in the case where the spans of columns are different due to the relationship between an existing building and an extension building adjacent thereto, both buildings adjacent to the connection site of the existing building and the extension building are listed. A connecting structure is disclosed in which only the columns at both ends of the columns are connected by tie plates, and the connection of the columns at the other intermediate positions is omitted.

Japanese Patent Laid-Open No. 9-279859

  The connection structure of the existing building and the extension building disclosed in Patent Document 1 has a large number of connection points between the columns in order to ensure the degree of freedom of the frame design in the relationship between the existing building and the extension building with different spans, In order to solve the problem that it takes a lot of labor and cost for the connection work, a convenient method was adopted in which only the pillars at both ends of the pillars of both buildings were connected, and the connection of the other intermediate pillars was omitted. It's just content. In other words, it is a configuration that is far from being established as a solution for the frame construction method regarding the difference in span allocation between areas with different uses and functions in the plan of a single building.

The object of the present invention is to provide various rooms as a plan of a small and medium-sized building having various rooms having different uses, functions, etc., such as the above-mentioned living room parts, common parts, lobby, guest pools, waiting rooms, etc. Divided into different areas for each application / function, and each area is independently assigned a span according to the application / function. It is to provide a frame construction method for a building capable of rationally realizing the frame.
The next object of the present invention is to divide an area where span allocation is determined in relation to an existing building and other areas as a plan of a building to be expanded adjacent to the existing building, and The span assignment according to the use, function, etc. is performed independently, so there are few restrictions on the floor plan, and it is possible to rationally realize the span assignment frame suitable for the use, function, etc. of each area. It is to provide a frame construction method.

As a means for solving the above-described problems of the prior art, the building frame construction method according to the invention described in claim 1 is:
Regarding the layout of the extension building 5 adjacent to the existing building 6, the span allocation of the columns 1 and 2 is determined from the area B in which the column / beam span allocation is determined in relation to the existing building 6 and other uses and functions. performs area classification of the area a, the area a, its use for each B, performed independently span allocation compatible column 1 beam 2 in function or the like, the different areas a, beamed a rack構間of B It is connected by the slab 8 of the corridor C which does not exist and continues in the X and Y biaxial directions .

According to the building frame construction method according to the present invention, as a planar arrangement in one building 5, optimum columns corresponding to areas A and B having different uses and functions by slabs continuous in the X and Y biaxial directions.・ Beam span allocation can be performed independently, and there is no restriction on the plan of floor plan. Moreover, it is not necessary to arrange the reinforcing bars diagonally in construction, and the arrangement work can be facilitated by ensuring good fit. Furthermore, it is possible to sufficiently ensure the usability in terms of use and function in each of the areas A and B.

In addition , in the expansion plan, for area B where the span allocation is determined in relation to the existing building 6, the span allocation of the existing building 6 is partially followed as it is, and other areas A are used and functioned. The degree of freedom in plan planning that implements the most suitable span allocation is ensured. In addition, it is possible to ensure ease of use in terms of usage and function for each of the areas A and B.

  According to the present invention, since the beam 2 does not exist in the corridor portion C that is continuous in the X and Y biaxial directions, which is an arrangement route for normal equipment piping, the equipment work such as equipment piping is never a troublesome beam penetration type. Don't be. And since it will pass under the slab 8, there is little effort on construction and the flexible freedom degree of an equipment meter surface is obtained. Moreover, it does not adversely affect the floor height in the room.

With respect to the plane arrangement of the build-building 5 adjacent to the existing building 6, wherein the existing building context of the 6 determines the span Allocation of columns and beams in Area B, other applications, the area determined assignment of columns and beams span function B is divided into areas, the spans 1 and 2 are determined independently for each of the areas A and B, and there is no beam between the frames of the different areas A and B. It connects by the slab 8 of the corridor C which continues to Y biaxial direction .
