Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of constructing a partition wall for partitioning floors of a concrete apartment complex, business office, or the like.

[Conventional technology]

Currently, there are two methods of constructing partition walls: constructing a wooden base or lightweight steel base on site and fixing wall boards to it, and using factory-produced wall panels (with wall boards fixed on both sides of the core material). The method used is to transport the panels to the site and install them across the ceiling and floor.

[Problem that the invention seeks to solve]

In the method of using a wooden shaft base, it is difficult to make the quality of the base wood uniform, and the strength of the base wood may locally decrease due to knots, etc., and the base wood may warp as it dries, resulting in poor accuracy and There are concerns about the strength in the future. In addition, the material cost is high, which is disadvantageous in terms of cost.

The method of using a lightweight steel frame base has low material costs and stable quality, but has the following drawbacks in workability and the installation condition of wall boards.

In other words, conventional partition walls using lightweight steel frames:
After attaching the upper and lower runners made of channel-shaped lightweight steel frames to predetermined positions on the ceiling and floor using concrete nails, etc., install similar lightweight steel columns between the upper and lower runners at both the top and bottom ends of each column. By inserting the connecting fittings attached to the upper and lower runners into the grooves and engaging them with the groove edges, it is installed, and then the wall boards are attached to both sides of the column and the upper and lower runners in the wall thickness direction with tapping screws. It is constructed using a method called fastening.

Therefore, until the wall board is installed, the support and the upper and lower runners are not rigidly connected, and the wall board is installed in a vertical plane, making the work of installing the wall board cumbersome. Additionally, since the back side of the wall board only touches the pillars and the upper and lower runners, the wall board tends to bend between the pillars, which can be inconvenient when attaching lintels, etc. to the surface of the wall board. .

The method of using factory-produced wall panels in advance is highly reliable in terms of accuracy and strength, and has good workability, but the wall panels are bulky and transportation costs are high, as well as being difficult to transport to the site. The end of the wall board may be chipped midway, and since the panel dimensions are constant, it is difficult to adjust the dimensions to account for construction errors in the building frame. Further, there are vertical core members (pillars) at both left and right ends of each wall panel, and two pillars are located adjacent to each other in the wall panel, so there is waste in the pillar material.

The present invention proposes a partition wall construction method that can eliminate the above-mentioned conventional drawbacks.

[Means for solving problems]

In order to achieve the above object, the method for constructing a partition wall according to the present invention involves opening connecting holes at a predetermined interval in a pair of left and right lightweight steel columns whose lengths are freely changeable on the upper side. A plurality of horizontal frames made of lightweight steel are formed at the arrangement pitch of the left and right columns, and a constricted portion having approximately the same length as the width in the wall direction of the column is positioned on the left and right columns, and the constricted portion is positioned in the connecting hole. By rotating the left and right columns, the lower ends of the left and right columns are connected to each other so that both side surfaces in the wall thickness direction are flush with each other. A wall unit connected to the runner and having a wall board fixed to at least one side in the wall thickness direction of the portion surrounded by the left and right pillars, the upper horizontal edge, and the lower runner is manufactured on site, and the wall unit is connected to the runner. The upper runners made of lightweight steel attached to the ceiling are installed at appropriate intervals across the floor, and the horizontal edges of adjacent wall units and the lower runners are connected to each other using light steel frames and additional runners. The runners are used to connect both side surfaces in the wall thickness direction so that they are flush with each other, and further, the wall thicknesses of the pillars, horizontal rims, upper and lower runners, additional rims, and additional runners other than the wall board fixing surface are The feature is that wall boards are fixed to both side surfaces.
