Description

The present invention relates to a method of laying a floor panel on a foundation, and then assembling a wall panel to construct a building. The present invention relates to a building method for building a building.

"Conventional technology" In order to enjoy a comfortable and affluent life from the needs of living in recent years, there is an increasing demand for a large house with a slightly larger indoor space.

However, due to the recent rise in land prices, it is difficult to acquire new land.For example, in the case of houses in an urban area, for example, it has been devised to increase the effective rate of the site by building a house full of the frontage, In this case, the so-called outer wall finishing work (plastering work, etc.) is required on the outer wall of the building, so if there is a building on the adjacent land, a minimum working space is required between the building and the adjacent land. I couldn't get it right and couldn't make effective use of the site.

Therefore, in the prior art, in order to eliminate the problem that such a dead space occurs between adjacent lands, a foundation is installed inside from the adjacent boundary in the premises, and the unit is placed on this foundation and its final installation position. Installed in a different position from
Means for effective use of the site by moving the unit onto the foundation and installing the unit at its final installation position after the external work of the unit is performed at this different position (for example, Japanese Patent Publication No. 1-12-1889 (Japanese Patent Application No. 58-9185 "Building Construction Method").

In the prior art, the unit is temporarily temporarily placed on a foundation sufficiently separated from a building on the adjacent land, and exterior work such as painting, draining work, rain gutter work, etc. is performed on the outer wall of the unit at the temporarily placed position, and thereafter, The unit which has been subjected to the exterior work is moved using rails, rollers, or the like to the final installation position of the unit located at a position full of the site boundary line on the adjacent building side.

"Problem to be Solved by the Invention" The present invention is to solve the following problem in the above-described conventional technology.

First, in the above-described building construction method in the prior art, the unit must be temporarily placed on the foundation once in order to perform exterior work on the outer wall of the unit. There was a problem that workability deteriorated because construction was not possible.

Secondly, in the prior art building construction method, in order to move the unit subjected to exterior work to the final installation position, for example, a plastic plate having a low coefficient of friction, rails, rollers, and the like must be provided on a foundation. The foundation of the house must be constructed in consideration of the movement of the unit, and as a result, there is a problem that the construction method is limited to a site where such a foundation can be constructed.

In addition, instead of the plastic plate, rails, rollers, etc., a unit for lifting the unit with a crane is also conceivable, but in this case, the crane must be put on standby at the site until the exterior work of the unit is completed, which reduces the workability. On top of that, there are problems such as crane rental fees and high costs.

In addition, when assembling the unit on the entire border of the adjacent land, it is difficult to position the unit on the foundation, and when the room unit and the foundation are integrated with the anchor bolt, it is not easy to locate the anchor bolt. There is.

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to construct a building along the border of a neighboring land even on a site where an existing building stands on the site of a neighboring land. Another object of the present invention is to provide a method of building a building that can be applied to any site, can improve its workability, and can reduce costs.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides a method of constructing a foundation on the entire boundary of the adjacent land in the premises, laying a first floor panel on the foundation, and then arranging the first floor wall panel. A method of constructing a building by assembling a floor panel on the second floor, further laying a floor panel on the second floor, and further installing a wall panel on the second floor. After the construction is completed in the factory to the final finish, these are combined on the site for two floors and the joint between the upper and lower wall panels is finished, and then the adjacent side wall panel of the size of the two floors is laid in advance. It is installed on a foundation in a state where it is positioned by the edge of the first floor panel.

[Operation] In the building construction method according to the present invention, the exterior construction of the wall panel located on the adjacent land side is completed in a factory,
After assembling the wall panels for which the exterior work has been completed for the second floor at the site, the joints are finished, and the wall panels combined for the two floors are suspended and installed on the foundation that has been constructed to fill the border line of the adjacent ground Since the process is adopted, the side wall panel of the adjacent land can be constructed at the site only by finishing the joint, and the construction of the neighboring land can be performed simultaneously with the construction work of the building at another foundation position.

Moreover, since the first floor panels are laid on the foundation before assembling the first and second floor wall panels, the wall panels must be positioned at the edges of the first floor panels when assembling these wall panels. Thereby, for example, the position of the anchor bolt protruding from the foundation can be easily performed.
