Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for joining upper and lower floor units in a unit construction method.

In the so-called unit construction method, each unit is delivered to the construction site with the finishing panels and walls already attached, so when joining the units vertically, high precision is required to fit each column together. is required.

However, in general, there are often some errors between the pillars of the units to be joined, so it may be impossible to join them with the walls etc. attached. The body had to be removed and reattached.

The present invention provides a joining method that allows units attached to a wall or the like to be easily joined vertically.

That is, the joining method of the present invention is a method for joining steel columns of upper and lower floor units when joining an upper floor unit of a form corresponding to the lower floor unit onto a lower floor unit, In addition to providing a joint bolt insertion hole in the capital of the steel column of the floor unit, a guide pin is fixed, and a joint bolt fixing part is provided at the lower end of the steel column of the upper floor unit corresponding to the joint bolt insertion hole. In addition to providing an insertion hole for the guide pin, the column head of the steel column of the lower floor unit is made swingable, and the guide pin is inserted into the guide pin insertion hole. The steel column of the upper floor unit is placed on top of the steel column of the unit, and then the upper and lower floor units are connected with the upper and lower floor unit joint bolts through the joint bolt insertion holes and the joint bolt fixing parts. This is for joining and fixing steel columns together.

Hereinafter, one embodiment of the joining method of the present invention will be described with reference to the drawings.

In the embodiment shown in the drawings, on a lower floor unit 1 having four steel columns 3, a structure corresponding to the lower floor unit 1 is installed.
This shows a mode in which an upper floor unit 2 having four steel columns 4 is joined together, and walls 10 are attached to two adjacent surfaces between each steel column 4 of the lower floor unit.

A joining bolt insertion hole 5 is bored in the capital of each steel column 3 of the lower floor unit, and a guide pin 6 whose tip is tapered and thin is arranged in line with the insertion hole 5.
are fixed, and a joint bolt fixing part 7 is provided at the lower end of each steel column 4 of the upper floor unit 2, corresponding to the joint bolt insertion hole 51, and the fixing part 7 A guide pin insertion hole 8 into which the guide pin 6 is inserted is lined up with
has been interviewed.

Also, the steel column 3 to which the two walls 10, 10 are attached
The capitals of the columns 3 are also integrally connected and fixed to the walls 10, 10, but the capitals of the other three steel columns 3 are made swingable. installed 2
A wall fixing plate 11 is attached to the capital of the main steel column 3.

In this wall body fixing plate 11', an insertion slot 12 for the guide pin 6 and an insertion slot 13 for the connection bolt 9 are bored parallel to each other and parallel to the wall surface of the wall body 10. It is inserted into the insertion slot 12 and mounted on the head of the steel column 3. In addition, at this time, one end of the wall body fixing plate 11 is arranged so as to be layered over the upper surface of the wall body 10, and the part to be placed on the upper surface of the wall body 0 is covered with a wall body. Two wall fixing bolt insertion slots 14 are bored in a direction perpendicular to the wall surface of the oven 0, and the wall fixing bolts are inserted through the insertion slots 141 from above to attach the wall fixing plate 11. and the wall 10.When joining the upper floor unit 2 of the upper floor to the lower floor unit, first, the steel columns 3 of the lower floor unit are connected. By inserting the guide pins 6 into the guide pinch holes 8' of the steel columns 4 of the upper floor units 2, the upper floor units 2 can be easily mounted on the lower floor units 1.

In other words, ``The capitals of the steel columns 3 of the lower floor units are all swingable except for one steel column 3, so there may be some errors in the column advisors of the upper and lower floor units. are also finely adjusted by the guide pins 6, and the upper floor unit 2 can be smoothly layered on the lower floor unit without removing the wall body 10.After that, the lower floor unit connecting bolts 9 are fixed to the respective lower floor unit connecting bolts. By inserting it into the insertion hole 5 and the joint bolt insertion slot 13 from below and fixing it to the joint bolt fixing part 7, the upper floor unit 2 and the lower floor unit are integrally joined and fixed.

Also, by inserting the wall fixing bolt 15 from above the wall fixing plate 11 into the wall fixing bolt insertion slot 14 and fixing it to the upper surface of the wall 10, the pivotable column head of the steel column 3 can be fixed. The wall body 10 is also completely joined and fixed via the wall body fixing plate blind 1. In the diagram, upper floor unit 2
Although there are no walls or the like attached to the lower floor unit 1, it is easily understood that even with the walls or the like attached, it can be joined and fixed to the lower floor unit 1 in the same way.

In addition, in the figure, 16 is the floor of the upper floor unit 2, 17 is a washer, and 18 is a nut that is competed with the guide pin 6 when the unit is transported. As mentioned above, ``According to the joining method of the present invention, even if there is some error between the upper and lower floor units when joining the upper and lower floor units, fine adjustments are forcibly made using the guide pins, so even if there is a slight error between the upper and lower floor units, fine adjustment is forcibly made using the guide pins. In addition, the upper and lower floor units can be easily joined, and by interposing the wall fixing plate as described above and illustrated, the wall can be easily and reliably joined and fixed to the steel column.
