Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a unit connecting device for connecting building units constituting a unit building.

[Prior Art] Conventionally, a unit connecting device for connecting left and right horizontally adjacent building units in an intermediate floor of a building where upper and lower building units are connected to each other has been used as a unit connecting device described in Japanese Utility Model Publication No. 53-1211. There is. This conventional unit coupling device is -
This method uses two connecting plates. That is, in the conventional device, - connecting plates are spread over the upper end surfaces of the steel frames r1 of the left and right lower floor building units, and these connecting plates are fitted into joint pins planted in the upper end surfaces of each steel column. , by fitting positioning holes provided in the lower end surfaces of the steel columns of the corresponding upper floor building units on the left and right into each joining bin that will pass through this connection plate (5), it is possible to It is at the same time a distant relative of the connection between the two and the connection between horizontal building units.

In other words, the order of installing units in a building using a conventional unit connection device is to install all the lower floor building units that make up the lower floor of the building, connect those lower floor building units with the above-mentioned connection plate, and then install the lower floor building units. Work to install building units on the same floor in horizontal rows is given priority over work to install building units on upper and lower floors in tandem, such as mounting an upper floor building unit on top of a building unit on a floor.

[Problems to be Solved by the Invention] However, for example, in medium-to-high-rise buildings with three floors or the like, it may be necessary to prioritize the above-mentioned vertical installation over horizontal installation. This is done so that when the entire building installation work cannot be completed in ■ days, the roof of the building may be partially erected to cover the rain, or ■ the length of the crane can be kept as short as possible. This is due to reasons such as a crane placed in an uninstalled part of the building to give priority to the adjacent installed part and build up the top floor.

However, in the conventional unit connecting device using one connecting plate, there are the following problems when vertical installation is involved.

That is, in this case, (1) Approximately half of the connecting plates of 1 ton (1 ton) will be installed between the building units on the upper and lower floors on one side of the horizontally adjacent left and right sides, resulting in 11 vertical installations. After this vertical installation, approximately half of the remaining portion of the connecting plate protrudes into the horizontally adjacent unit installation area on the other left and right sides.

■When performing a new vertical installation in the horizontally adjacent installation area after the vertical installation described above, the lower floor building unit must be lowered without colliding with the protruding part of the connecting plate that protrudes greatly in the above ■. After that, the lower floor building unit is slid sideways onto the foundation or a lower building unit, and the upper end surface of the steel column of the lower floor building unit is positioned at a predetermined position on the lower surface of the protruding portion of the connection plate. This will involve extremely complicated and difficult installation work.

An object of the present invention is to easily and reliably connect horizontally adjacent building units when installing building units on upper and lower floors in columns in priority order over installing building units on the same floor in rows. shall be.

■When installing a building, if vertical installation is to be given priority, will the first connecting plate be installed between the building units on the upper and lower floors on one side of the horizontally adjacent left and right sides to perform vertical installation? After this vertical installation, the third connecting plate simply causes its tongue-like connecting portion to protrude into the gap between the left and right building units that are horizontally adjacent to each other. That is, the first connection plate does not allow its tongue-like connection portion to extend far into the unit installation area on the other left and right sides.

■When performing a new vertical installation in a horizontally adjacent installation area after the vertical installation described above, the lower floor building units on the other horizontally adjacent left and right sides should be moved to the specified installation position on the foundation or lower building unit. hang it down. At this time, a second connecting plate is attached to the upper surface of this lower floor building unit, and this second connecting plate causes its tongue-shaped connecting portion to protrude horizontally into the gap between the left and right adjacent building units. .

■ Then, if necessary, after correcting the position by lifting the lower floor building unit in (2) above, connect the tongue-like connecting portions of the first and second inner connecting plates with connecting tools such as bolts and nuts. .

■When installing building units on the upper and lower floors in columns in accordance with the above ■ to ■, giving priority to installing building units on the same floor in rows, horizontally adjacent building units can be easily installed and their positions corrected. After that, these building units can be easily and reliably connected.

According to the present invention as set forth in claim 2, there is the following effect (2).

■Since the first and second inner connecting plates are connected at the end faces of the steel columns of each building unit, high connection strength can be ensured.

According to the present invention as set forth in claim 3, there is the following effect (2).

■Of the first and second reconnection plates, the connection plate installed between the upper end surface of the steel column of the lower floor building unit and the lower end surface of the steel column of the upper floor building unit is the one that connects the upper and lower floor building units. Because it is attached between the building units on the upper and lower floors by being fitted into the joint bin for 6, it is possible to simultaneously achieve the connection of the building units on the upper and lower floors and the connection of the building units on the horizontal floor. I'll come.

According to the present invention as set forth in claim 4, there is the following effect (2).

■By bending and forming the tongue-like connecting portion of at least one of the first and second inner connecting plates, the tongue-like connecting portion is connected while the inner connecting plate is attached to the corresponding building unit. Since the portions are biased in opposite directions to each other, the tongue-shaped connecting portions can be reliably connected without interfering with each other.
