Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method of constructing a steel frame for a building in which welding distortion is less likely to occur (and erection distortion can be easily corrected).

(b), Prior Art FIG. 3 is a diagram showing a conventional method of constructing a steel frame in a building.

Conventionally, when constructing this type of steel frame, as shown in FIG. 3, the connecting portion 1c of the steel frame 1, tctt! They were connected by welding on the same layer.

(C) 0 Problems to be Solved by the Invention However, in such a method, the layers to which the steel frame l is connected are biased toward a specific layer, and the welding strain is concentrated in the layer where the welding is performed. There was an inconvenience that required some kind of countermeasure to be taken.

In addition, when correcting the strain during erection of the steel frames 1, since the steel frames 1 that have been erected are lined up at the same horizontal level as shown in Figure 3, adjacent steel frames 1 interfere with each other, making corrections difficult. This will cause the inconvenience that it will take.

In order to eliminate the above-mentioned drawbacks, the present invention aims to provide a method for constructing a steel frame in a building in which welding strain is not concentrated in a specific layer and construction strain can be easily corrected. It is something to do.

(d) Means for solving the zero problem, that is, the present invention provides a connecting portion (
ICs) are built in such a way that they are not placed on the same layer.

Note that the numbers in parentheses are for convenience and indicate corresponding elements in the drawings, and therefore, this description is not limited to the descriptions on the drawings. The following r (el
The same applies to the column ``, action''.

(e) 0 effect With the above-described configuration, the present invention provides the connection portion (
1c) is distributed to each layer, the welding strain is also distributed to each layer, and the tip of the erected steel frame (1) is not restrained by other steel frames (1), making it possible to correct the erected strain. It works so that it can be done easily.

(f), Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a diagram showing an example of a building to which an embodiment of the method for constructing a steel frame according to the present invention is applied, and FIG. 2 is a diagram showing another embodiment of the present invention.

As shown in Fig. 1, the building 2 has a plurality of built-in steel frames 1, and the steel frame 1 has a rod-shaped column component 1a and is formed at right angles to the column component 1a. Beam structural part 1b
have. Connecting parts 1c for vertically connecting the steel frames 1 by welding are provided at both upper and lower ends of the column component 1a of each steel frame 1. The connecting parts 1c are assembled in a staggered manner so that the connecting parts 1c are not arranged on the same layer. In addition, in FIG. 1, symbols CL1, Cl3, C
l3 represents each layer in the building 2.

(g) 0 Effects of the Invention As explained above, according to the present invention, since the connection ICs of the steel frames 1 adjacent to the left and right are constructed so as not to be placed on the same layer, the connections of the steel frames 1 The welding strain that occurs during welding is dispersed in each layer, and is no longer concentrated in a specific layer, making it unnecessary to take special measures to remove welding strain. Furthermore, as shown in FIG. 1, the tip 1d of the newly constructed steel frame 1 is
Since the steel frame 1 is not constrained by other existing steel frames 1 due to misalignment of the steel frame, it is possible to easily correct the distortion caused by construction.

In addition, although the above-mentioned example described the case where the beam structure part 1b was previously provided on the steel frame 1, the beam structure part 1b is not necessarily necessary, and for example, as shown in FIG. Of course, it is also possible to erect only the column component 1a and then connect the beam steel frame 3. Further, the number of beam structural parts 1b provided in the column forming part 1a may be any structure such as three layers and one section, in addition to the two-layer, one-section structure shown in FIG.
