[Detailed description of the invention] [Industrial application field] The present invention relates to building units.

[Conventional technology]

Recently, unit buildings have become widely used in order to increase the industrial production rate of buildings and reduce the cost required for construction. The unit building is a special public building built in 1982.
As shown in Publication No. 30987, this is a type of building in which a single building is divided into several building units that are produced in advance at a factory, and these are constructed and assembled at the construction site.

Fig. 9 is a perspective view showing a construction method for a unit building using a general wall construction method; Fig. 10 is a partially cutaway perspective view showing a conventional building unit used in the unit building shown in Fig. 9; The figure is a sectional view showing the state of connection between floor panels and wall panels in a conventional building unit.

Unit building 10 is a two-story residential building,
It is formed by connecting building units 11 vertically and horizontally. The building unit 11 constituting the unit building 10 is manufactured in advance in a factory etc.
It is assumed to have certain standard dimensions. The building unit 11 is assumed to have a certain external length L1, external width W1, and external height H1 as shown in FIG. In this way, a unit building 10 having a certain standard shape and standard dimensions can be completed. As shown in FIG. 10, the building unit 11 has rectangular wall panels 15A and 1 on the upper surface of the outer peripheral edge of the rectangular floor panel 14, respectively.
5B and 15C are connected in an upright state. The floor panel 14 is a floor frame 1 arranged vertically and horizontally.
6, and then the floor frame 16 is attached.
A base 18 is attached to the lower part of the base 18. On the other hand, each wall panel 15A, 15B, 15C is formed by attaching panel materials 21A and 21B to both sides of a wall framework 20 arranged vertically and horizontally.

Floor panel 14 and each wall panel 15A, 15B, 1
5C is made by driving nails 24 or the like between the wall frame 20 of the wall panels 15A, 15B, and 15C, the face material 17 of the floor panel 14, and the floor frame 16, as shown in FIG. There is. This results in
Floor panel 14 and each wall panel 15A, 15B, 15
C are connected and integrated to form a building unit 11.

Furthermore, the building units 11 formed by the above method are vertically and horizontally adjacent to each other.
The building unit 10 is a two-story unit building 10, and in this case, the connection between the building unit 11 constituting the upper floor and the building unit 11 constituting the lower floor is the floor frame 16 of the floor panel 14 of the building unit 11 constituting the upper floor. Wall panels 15A, 1 of building unit 11 constituting the lower floor
The wall frames 20 of 5B and 15C are connected using connection members such as nails.

[Problem that the invention seeks to solve]

However, in the above conventional example, the height H
Each wall panel 1 with the height of the wall framework 20 being H2 is placed on the upper surface of the outer peripheral edge of the floor panel 14 having a height of H2.
Connect 5A, 15B, 15C and make external height H1
Since the building unit 11 was formed with
If one or both of the height H3 of the floor panel 14 or the height H2 of the wall frame 20 causes an error with respect to the standard dimensions, the external height H1 of the building unit 11 formed by connecting them will also comply with the standard. There is a possibility that a relatively large error in dimensions may occur.
For this reason, conventionally, for example, the building unit 11 whose external height H1 has been formed higher than the standard dimensions,
The height was adjusted by cutting the base 18 of the floor panel 14.

Furthermore, when the building units 11 formed by the method described above are connected vertically and adjacently, for example, the wall panels 15A, 15B, 15C of the building unit 11 arranged on the upper floor and the wall panels 15A, 15B, 15C arranged on the lower floor are connected. Each wall panel 15A, 15B of the building unit 11 to be installed,
15C were not directly connected to each other, but the floor panels 14 of the building units 11 installed on the upper floor were installed between the corresponding wall panels above and below. This results in a decrease in bonding strength.

Further, in the building unit 11, each of the wall panels 15A, 15B, 15C is connected to the upper surface of the outer peripheral edge of the floor panel 14, and the height of the wall frame 20 is H2. is the height of the room in the building unit 11, so it is difficult to change the height of each room in the building units 11 having the same external dimensions.

The present invention aims to improve the height dimensional accuracy of building units, improve the bonding strength between vertically adjacent building units, and make it possible to adjust the height of the room formed by the building units.

[Means for solving problems]

In order to achieve the above object, the present invention provides a building unit using a frame wall construction method consisting of a floor panel and a wall panel. The periphery is to be connected.

[Effect]

According to the present invention, the floor panel and the wall panel in the building unit are connected by connecting the outer peripheral edge of the floor panel to the groove in the inner side view of the wall panel. It becomes possible to standardize the setting of the height dimension using only the height dimension of the wall panel, thereby making it possible to improve the height dimension accuracy of the building unit.

Furthermore, when constructing a multi-story unit building with adjacent building units above and below, it is possible to directly connect the wall panels of the building units that make up the upper floors and the wall panels of the building units that make up the lower floors. This makes it possible to improve the joint strength between vertically adjacent building units.

Further, according to the present invention, it is possible to connect the outer peripheral edge of the floor panel to any external height position of the inner side surface of the wall panel, making it possible to adjust the height of the room formed by the building unit. I can do it.
