Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an L-shaped unit building member for a lightweight steel structure in which a wall-resistant structural element composed of columns, walls and beams of a lightweight steel structure is integrally formed as a constituent unit (unit) including a corner portion. . A beam or a beam is a generic term for a horizontal running member, and a beam or beam joined to the upper part of a column is referred to as an upper runner and a base beam joined to the lower part of a column is referred to as a lower runner.

[0002]

[Prior art]

 Conventionally, in many light steel structure buildings, a method of attaching plates to columns, making holes in beams, and fastening them with bolts and nuts has been adopted as a wall-resistant structure. In this case, if the altitude is high, the stability is poor, and it takes time and effort to attach beams and braces.

As one of the solutions to this problem, a so-called box construction method has been proposed in which a wall-resistant structure is formed by using ready-made surface members (units) in which columns and beams are welded. There are four beams each, and there is a problem that columns and beams overlap at other connection locations. In addition, the unit itself becomes large and the weight also increases, so that there is a problem that a work load such as transportation is added.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of such circumstances, and the structure is formed on the premise of strength and economy by integrally forming the wall-resistant structural element as a structural unit (L-shaped unit) including a corner portion. It is an object of the present invention to provide a lightweight L-shaped unit building member for steel structures which can be simplified and improved in workability. Further, it is possible to provide a new construction method using the L-shaped unit construction member of the present invention (tentatively called L-shaped construction method).

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is an L type for a lightweight steel structure in which a wall-resistant structural element including a column, a wall and a runner of the lightweight steel structure is integrally formed as a structural unit (unit) including a corner portion. It is a unit building member, and it is made by combining a plurality of columns and runners to the upper and lower parts between these columns and joining them, and shaping them so that they have L-shaped corners in a plan view shape in an upright state.

Example 2 FIG. 2 is (a) a plan view and (b) an elevation development view showing an isosceles L-shape.

As shown in the figure, the unequal side L type (Y) is formed by combining four columns (1) and runners (2; 21, 22) at the upper and lower parts of the columns (1) and joining them. It has a wall portion (3) having one surface and two surfaces respectively formed at right angles, and is shaped like an unequal side L-shape in a plan view in a standing state.

Example 3 FIG. 3 is a plan view (a) and an elevational development view (b) showing an equilateral WL type.

As shown in the figure, in the equilateral WL type (Z), the four pillars (1) and the runners (2; 21, 22) are combined with the upper and lower parts of the pillars (1), and are joined to each other to make them horizontal. It has a wall part (3) consisting of two surfaces in one direction and one surface in a direction perpendicular to each other. The plan view shape in the standing state is shaped into a double L shape (or inverted T shape) of equal sides. There is.

FIG. 4 shows (a) a plan plan and (b) an elevation plan of a lightweight steel structure using a combination of the equilateral L-shape of Example 1 and the unequal-side L-shape of Example 2. It is a figure.

As shown in the drawing, when the members (X, Y) of Examples 1 and 2 are combined to construct a lightweight steel structure by the L-shaped construction method proposed by the applicant, the room (6) is By placing an equilateral L-shape (X) at the normal corner to be formed and an unequal L-shape (Y) at the corner where the passage or opening is adjacent, the runner (2) can be made short and stability and strength can be obtained. be able to. If necessary, window sashes and door sashes can be attached in advance to the intermediate runners and wall members between the members (XX, YY, XY), which also contributes to simple construction. .

Also in the elevation plan, since the second floor and the third floor can be joined as through columns (illustrated as 2L and 3L), the strength can be increased. In addition, since the roof part has a separate structure, you can select folding boards, gables, barnhouses, and parlors.

Furthermore, in a two-story or three-story apartment with a long ridge (horizontal) direction, an equilateral WL type (Z) is opposed to the joint in the connecting (arranging) direction of the rooms (6) on each floor. To intervene. A plane plan for explaining this outline is shown in FIG.

[Effect of device]

 The present invention has the above-mentioned structure. According to the present invention, the wall-resistant structural element can be further simplified on the assumption of strength and economy, and the construction is easy, and the lightweight steel as a whole. Construction costs can be reduced, including shortening the construction period.

In particular, since the pillars are through pillars, the wall resistance strength of the second and third floors is increased.

Further, since three points are installed at the same level during construction, almost no adjustment (base surface adjustment) is required.

Further, since it is provided as a ready-made member with the wall surface fixed, it is possible to additionally install wall materials, sidings, sash windows, etc. according to options at the time of factory production, which also shortens the construction period. .
