Definitions
- the present invention relates to a method of extending an existing building and a building extended by this method. More specifically, the present invention relates to an existing building having a structure in which a plurality of buildings are connected by a crossing corridor while using the existing building. The present invention relates to an extension method that can be expanded upward, can secure sufficient building strength, and can effectively use an empty space, and a building extended by this method.
- Patent Document 1 The invention described in Patent Document 1 is a novel construction in which a new foundation is provided so as to surround the existing building, and a steel column is erected above the new foundation to construct a new building above the existing building. This is an excellent invention that can solve many of the problems associated with conventional extension methods.
- the extension method disclosed in Patent Document 1 is an excellent method for applying to the extension method of a detached house. For example, when an existing building is large in plan. In some cases, there may be a problem with strength.
- the extension method disclosed in Patent Document 1 is to build a beam between extension columns that are erected so as to surround the outside of an existing building, and build a new upper floor above this beam. Therefore, if the existing building is large in plan, it is located above the existing building. The span of the beam to be erected becomes long, and as a result, it may be difficult to ensure sufficient strength to withstand the weight of the upper floors built on top of existing buildings.
- the existing elementary and junior high school buildings have a relatively large number of buildings with a plurality of buildings connected by crossing corridors.
- Patent Document 1 there is a space between buildings separated by a corridor.
- Patent Document 1 When the technology disclosed in Patent Document 1 is applied as it is, it will be taken into the expanded building as it is. It was difficult.
- Patent Document 1 the applicant of the present application has made it possible to apply the disclosed technology of Patent Document 1 to a store building with a wide front width such as a convenience store in view of the above-described problems of strength.
- the technology has already been proposed (see Patent Document 2).
- Patent Document 2 describes a concrete panel force in which a beam is composed of a concrete beam including a reinforcing member in the axial direction, and a panel spanned between the beams is provided with a reinforcing member in the length direction. The technology that constitutes it is disclosed.
- Patent Document 2 it is possible to solve the above-described strength problem, but since a specially strengthened beam or panel is used, it is favorable in terms of construction cost. It was not good, but it was an economic method, but it was powerful.
