Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an angle cat unit for a steel frame structure, and more particularly, to an angle cat unit in which an angle cat used for attaching a purlin, a furring strip, etc. is previously integrated with a steel structure member.

[0002]

[Prior art]

 In steel-based structures, various steel frame structural members such as columns, beams and furring strips are used.By connecting these steel frame structural members to each other, various steel frame structures such as houses and bridges are constructed. There is.

In order to facilitate the connection of such steel frame structural members, an L-shaped metal fitting called an angle cat has been conventionally used. By fixing one surface of the L-shaped metal fitting to, for example, the furring edge side, another steel frame structure member can be connected to the other surface of the L-shaped metal fitting in a direction perpendicular to the furring edge.

[0004] Conventionally, since attachment of such an angle cat to a steel frame structural member requires accurate positioning in millimeters, ink marks are marked by measuring attachment points according to the drawings, and the angle cat is temporarily tack welded. Then, the main welding is performed after that.

[0005]

[Problems to be solved by the device]

 However, the following problems arise when connecting by welding in the field as described above.

[0006] That is, measurement errors are likely to occur and accurate positioning is not possible, provisional welding and main welding are required, resulting in poor productivity. Sparks, smoke, dust, etc. are generated during welding work, resulting in poor work environment and burns. There is a risk of visual impairment, hardness welding technology is required, and labor costs are high.

Therefore, an object of the present invention is to provide an angle cat unit for a steel frame structure, which does not cause the problems of the welding method described above in connecting the steel frame structure member and the angle cat.

[0008]

[Means for Solving the Problems]

 The angle cat unit for a steel structure of the present invention forms a through hole at a predetermined position of a steel structure member, and forms a through hole in an L-shaped angle cat corresponding to the through hole, thereby forming the steel structure. The through hole of the member and the through hole of the angle cat are aligned and arranged, and the bolt is inserted through the through hole of the steel structure member and the through hole of the angle cat, and the bolt and the nut screwed to the bolt. The above object is achieved by integrating the angle cat and the steel structure member.

Here, as the bolt and the nut, those which are normally used can be used.

Further, the formation of the through hole in the steel frame structure member is performed by a lip groove forming system (manufactured by Amada Metrex Co., Ltd.) capable of highly accurate and consistent work by computer control capable of accurate positioning. You can

[0011]

[Action]

 Since a through hole is formed in the steel frame structural member and the angle cat and they are integrally connected by bolts and nuts, there are no problems caused by welding. Also, by pre-integrating, the installation work on site will be greatly improved.

【Example】

 The features of the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is an overall view of a house constructed by the angle cat unit for steel structure of the present invention, FIG. 2 is an enlarged view of part A of FIG. 1, and FIG. 3 is a steel structure used for the house of FIG. It is a perspective view of an angle cat unit for things.

Referring to FIG. 1, 1 is a steel main body column made of H-shaped steel provided at both ends and the center of a house, 2 is a steel frame main body connecting the upper ends of the steel frame main columns 1, and the lower part is horizontal. A horizontal furring strip 3 arranged in the direction is provided, and a furrow furring strip 4 is further provided at the top. Reference numeral 5 is a window forming frame. Further, vertical furring strips 6 having a C-shaped cross section are arranged at substantially equal intervals in the vertical direction.

With reference to the enlarged view shown in FIG. 2, the horizontal furring strip 3 and the vertical furring strip 6 are connected and integrated at a right angle, and an angle cat 7 is provided at the connecting portion. 8a is a mounting bolt that connects the angled cat 7 and the horizontal furring strip 3, 8b is a nut that is screwed to this, 9a is a mounting bolt that connects the angled cat 7 and the vertical furring strip 6, and 9b is this It is a nut.

The angle cat 7 is unitized by being preliminarily manufactured in advance by connecting it to the horizontal furring strip 3 to form a unit. As shown in the perspective view of FIG. 3, a through hole 3 a is formed at a predetermined position of the horizontal furring strip 3. The L-shaped angle cat 7 is also formed with a through hole 7a corresponding to the through hole 3a. Then, the through hole 3a of the lateral furring strip 3 and the through hole 7a of the angle cat 7 are aligned and aligned, and the nut 8b is screwed to the bolt 8a using the impact wrench 10 to be integrally connected.

As described above, in the angle cat unit for the steel structure of the present embodiment, the lateral furring strip 3 and the angle cat 7 are integrally connected in advance by the bolts 8a and the nuts 8b. There are no problems like the conventional welding method. In addition, since on-site welding is not required, production efficiency has improved by a factor of three, and no special engineer such as a welder is required, making it possible for inexperienced people to assemble.

In the above-described embodiment, the horizontal furring strip 3 and the angle cat 7 are connected and integrated. However, the present invention is not limited to this. The same applies to the frame 5.

[0019]

[Effect of device]

 As described above, the angle cat unit for a steel structure of the present invention has through holes formed in the steel structure member and the angle cat, respectively, and these are integrally connected by the bolt and the nut. So no problems arise due to welding. In addition, since the steel frame structural member and the angle plate are unitized by preliminarily connecting and integrating, installation work on site is greatly improved.
