Description

  The present invention relates to a temporary column structure in which a temporary column having a certain height is provided in a column omitted portion of a building.

Generally, a column beam type unit building is constructed by installing adjacent building units in which columns, floor beams and ceiling beams are joined in a box shape. Therefore, in general unit buildings, the four corners of each building unit (
There is always a pillar in the corner), and as a result, the pillar (multiple pillars) always stands in the center of the unit building where the corners of multiple building units are placed against each other and are not obstructed by the pillar A wide and continuous living room space cannot be formed.

On the other hand, there exists a thing of patent document 1 as a unit building which can abbreviate | omit a pillar in the butting | matching part of a building unit. In this prior art, a column omitted building unit is used in which a column is omitted at at least one corner of the building unit, and a temporary column is attached to and detached from the column omitted corner. And the temporary pillar in this conventional column-omission building unit is divided into at least two in the longitudinal direction, the divided pillars are brought into contact with each other at their end faces, and are detachably connected with connecting bolts.

In general, in the construction of a unit building, it is necessary to set the total height of the temporary column to a column height that is accurately omitted in order to ensure building dimensional accuracy when the building unit is assembled. However, since the above-mentioned prior art temporary columns are formed by connecting the divided columns with each other without any gap between them, the connecting bolts are removed to remove the divided columns after the building unit is installed. However, it is difficult to pull out the split columns laterally because the split columns collide with each other under the action of the axial force.

Therefore, Patent Document 2 proposes a temporary column structure having a height adjusting means using two height adjusting bolts and two connecting bolts at the connecting portion of the temporary column.

Patent Document 3 proposes a temporary column structure in which the temporary column includes upper and lower connecting portions and a connection height adjusting means including a single bolt.

In the upper pillar 21 around the long hole of the outer cover 23 and the upper overhanging portion 3 of the outer cover 33
It will be fastened in a state of locking around each of the 3A long holes.

According to the present embodiment, the following operational effects can be obtained.
(a) When the building unit 10 is assembled, the upper column 21 and the lower column 3
1 and the upper column 21 and the lower column 31 are connected to bolt connecting means (bolts 41 and 42, nuts 41A,
42A), the slope 21A of the lower end surface of the upper column 21 slides up the inclined surface 31A of the upper end surface of the lower column 31, and the sum of the upper column 21 and the lower column 31 is reached. The height is gradually extended from the contracted state. When the bolt connecting means (bolts 41 and 42, nuts 41A and 42A) are set in a combined state in which the central axes of the upper column 21 and the lower column 31 are aligned, both the columns 21 and 31 have their total height, in other words, The total height of the temporary pillar 20 is set to a predetermined constant height H.

(b) The upper column 21 and the lower column 31 are constrained by the bolt coupling means (bolts 41 and 42, nuts 41A and 42A) in the combined state of (a), and become the temporary column 20 that can sufficiently withstand the axial load.

(c) When the temporary column 20 is removed after the building unit 10 is installed, the bolt connecting means (bolts 41 and 42, nuts 41A and 42A) is removed from the upper column 21 and the lower column 31 except for the binding force. The slope 21A on the lower end surface of the column 21 slides down the slope 31A on the upper end surface of the lower column 31, and the total height of the upper column 21 and the lower column 31 gradually contracts. It can be pulled out laterally from the omitted part.

(d) The drawing end of the upper column 21 and the lower column 31 (a) by the bolt connecting unit (bolts 41 and 42, nuts 41A and 42A) is the regulating unit (the lower projecting portion 23A and the lower column 31 of the upper column 21). Therefore, the upper column 21 and the lower column 31 constituting the temporary column 20 can be easily set to a complete combined state in which their central axes coincide with each other.

(e) In the combined state of the upper column 21 and the lower column 31 in the above (a), both the columns 21 and 31 are engaged with locking means (bolt 4
1, 42) are locked together in the separation direction along the axial direction, so that the tensile force acting in the axial direction of the temporary column 20 when the building unit 10 is lifted can be withstood.

(f) In the combined state of the upper column 21 and the lower column 31 constituting the temporary column 20, the holding portion 25 </ b> A of the upper column 21 holds the held portion 35 </ b> B of the lower column 31, and the lower column 31 is held The part 35A is the holding part 25 of the upper pillar 21.
Since B is held, the upper column 21 and the lower column 31 are not twisted around their central axes in their combined state.

With respect to the separation direction along the axial direction of 31, the locking means for locking the two columns 21 and 31 to each other is constituted. That is, in the combined state of the upper column 21 and the lower column 31, both the columns 21 and 31 are separated from each other along the axial direction due to the presence of the locking means (the upper inclined surface 23B of the upper column 21, the downward inclined surface 33B of the lower column 31). And can withstand the tensile force acting in the axial direction of the temporary column 20 when the building unit 10 is lifted.

The temporary pillar 20 is composed of an upper pillar 21 and a lower pillar 3 by only one bolt 51 instead of the bolts 41 and 42.
The ones are pulled toward each other in the direction perpendicular to their axes so that they can be set in a combined state. Bolt 51 is
It is inserted into a long hole provided in the column main body 22 and the outer cover 23 of the upper column 21, and the outer cover 33 of the lower column 31.
Fastened to a long nut 51A welded to the back surface of the upper overhang 33A. The front end of the bolt 51 does not protrude from the outer surface of the temporary column 20, and the long nut 51 </ b> A is not exposed to the outer surface of the temporary column 20, so that the configuration can be simplified.
