Description

[Detailed Description of the Invention] According to the present invention, connecting metal tubes are fitted inside the metal tubes on both sides, which are disposed at the butt joints with the pipe ports facing each other, in the state of being installed in the metal tubes on both sides. The present invention also relates to a structure of a joining portion of metal tubes, characterized in that a hardening raw material is provided in the metal tubes on both sides and the metal tube for joining and is hardened.

Figure 2 shows a building frame in which frame members A, which consist of a quaternary formed in a square and columns protruding from its four corners, are arranged side by side and stacked and connected. An example of a building is shown in which a shell B with a wall on one side and a shell C with walls on two sides are arranged side by side and stacked and connected. Further, in Fig. 3, wall panels D with protruding quasi-end portions 1 are arranged facing each other at intervals, and an intermediate quasi-2 is constructed between the quasi-end portions 1 and 1 to connect them. Other examples of stacked and bonded buildings are shown.

This invention can be used when building members such as frame members, shells, panels, etc. are arranged side by side and stacked and connected together as shown in Figs. 1 to 3, and Figs. 4 to 9 are shown in Figs. An example of the arrangement of such building components is shown below.

Incidentally, as shown in FIGS. 7 and 9, slabs 3 may be constructed and connected between building members such as shells arranged at intervals, or as shown in FIGS. 8 and 9. It goes without saying that the wall portion 4 may be replaced with a pillar in an example of arrangement. Moreover, each building member may be arranged in reverse and connected.

Next, using a steel-framed concrete shell as an example of a building member, the structure of a connecting portion of a building member that utilizes the parenthesis invention will be described.

Figures 10 and 11 show a plurality of connecting metal pipes 8 between the upper pipe openings of the metal pipes 6.6 of a plurality of lower steel frame concrete shells each having a metal pipe 6.6 installed therein. .8
The bonding material 7 that has fixed the bonding metal tube 8.8 to the metal tube 6
．． 6, respectively, and a metal tube 6'. A plurality of upper steel-framed concrete shells each having a metal pipe 6'. 6' is opposed to the upper end of the metal tube 6.6, and the metal tube 6'. 6' is mounted on the connecting metal tube 8.8, and reinforcing bars are installed in the upper and lower metal tubes 6.6' and in the connecting metal tube 8 installed in an erected state therein. 9 is provided, a hardening raw material 10 such as concrete is provided and hardened, and a plurality of upper and lower steel-framed concrete shells are connected.

The metal pipes 6 are installed as pillars at the four corners of the steel-framed concrete shell, and a metal base 5 is installed in between the metal pipes 6 and 6.

Although one embodiment of the present invention has been described above, the building components in the above embodiment include steel-framed concrete, steel-framed reinforced concrete, or steel-frame framework materials with fireproof coatings, walls, and floors, etc. can be used.

Since the present invention is constructed as described above, the metal tubes on both sides, which are disposed at the butt joints with their pipe ports facing each other, can be joined together in a very cylindrical and secure manner without the need for welding or pin-jointing. Not only do the metal pipes on both sides have a high bending strength because they are combined with the hardened material provided in each tube, but the joint part has a double pipe structure with hardened material, which increases the strength even more. It has many effects, such as being able to resist external forces when integrated, and being used to connect building members as in the embodiment.
