Description

The present invention relates to a structure of a vertical frame member in a house composed of a thin and light steel member such as a steel house, and a vertical frame member fixing device. Here, the steel house is defined as a steel structure building composed of a thin lightweight steel having a thickness of 0.4 mm or more and less than 2.3 mm.

  The building frame material is formed by roll forming a thin steel plate to have a cross-sectional shape such as a groove shape, a groove shape with a lip, and a box shape, and the width dimension is also formed in accordance with a predetermined use form. When doing so, it is used as a single member or as an assembly member in which a plurality of members are joined with a drill screw, and these frame members are joined together with a drill screw or the like to construct the main frame of the building.

  There are various cross-sectional shapes of the frame material configured by combining the various groove steels, but the cross-sectional shape may be limited depending on the place of use. For example, the opening part side of the vertical frame member provided on both sides of the opening part such as the doorway and the window in a building such as a steel house needs to be a plane in terms of attaching a lintel.

  Explaining with FIG. 3, the vertical frame member 2 disposed on both sides of the opening 1 is fixed with a lintel 12 disposed on the upper portion of the opening 1 in addition to the function of a general vertical frame member. Two functions are required. In other words, a member called a lintel 12 is disposed above the opening upper frame member 4 at the top of the opening 1, and both ends of the lintel 12 are connected to the opening 1 via the lintel receiving member 13. It joins to the vertical frame material 2 arrange | positioned on both sides. Therefore, it is necessary to make it the structure which can join the lintel receiving material 13 to the edge | side which faces the opening part 1 of the vertical frame material 2 of the said opening part both sides.

  More specifically, a plurality of vertical frame members 2 rise from the lower frame member 5 at a predetermined interval, and the upper ends of the vertical frame members 2 are coupled to the upper frame member 6, and A wall material composed of the frame material 2 and the upper frame material 6 is fixed to a face material 10 such as a structural plywood with a drill screw 8.

  As shown in FIGS. 4 and 5, the vertical frame member 2 arranged on both sides of the opening 1 is an assembly H formed by fastening the webs 20 of the two lip-shaped channel steels 2 a and 2 b with a drill screw 8. Shape steel is mainly used. The vertical frame member 2 is made of light grooved steel for attaching the lintel 12 and receiving the lintel receiving material 13 even when the two lip grooved structural steels 2a and 2b have sufficient axial force strength. The covering material 14 is joined.

  Then, the covering material 14 is fixed to the grooved steel 2a with the lip on the opening side in the vertical frame material 2 by the drill screw 8, and the lintel receiving material 13 is fixed to the covering material 14 by the drill screw 8, and the lintel receiving material. 13, the lintel 12 is attached with the drill screw 8 to construct the lintel junction structure in the opening. The lintel 12 is a panel shape having a predetermined thickness and a predetermined dimension.

  As described above, in the vertical frame member 2 on both sides of the opening 1, another light grooved steel for attaching the lintel receiving member 13 to the grooved steel 2 a with a lip located on the opening side. It is the present condition that the covering material 14 which consists of is joined.

  In addition, the lower frame member 5 made of a thin and lightweight channel steel is installed on the base 15 with the opening facing upward, and the vertical frame member 2 stands up from the inner surface of the web of the lower frame member 5, and the vertical frame member 5 2, the lower frame member 5, and the foundation 15 are joined by a hole-down hardware 16.

  The hole-down hardware 16 is configured by reinforcing a horizontal portion 17 and a rising portion 18 with a reinforcing plate 19. The hole-down hardware 16 is disposed in the groove portion of the grooved steel 2b with the lip opposite to the opening 1, and the rising portion 18 of the hole-down hardware 16 is applied to the web 20 and a drill is applied to the contact portion. Both members are joined by driving a screw 8.

  Further, the horizontal portion 17 of the hole-down hardware 16 is placed on the web 5a of the lower frame member 5, and the upward projecting portion of the anchor bolt 21 embedded in the foundation 15 is connected to the horizontal portion 17 and the bolt insertion hole 22 of the web 5a. After being inserted, the nut 23 is fastened to the threaded portion at the protruding tip. Thereby, the vertical frame member 2 can be fixed to the foundation 15 through the hole-down hardware 16.

  As described above, the covering member 14 made of channel steel is attached to the opening portion side of the vertical frame member 2 located on both sides of the opening portion 1. Since it interferes with the flanges 24 of 5 and 6, it is provided shorter than the grooved steels 2a and 2b with lips in the vertical frame member 2. Accordingly, the covering member 14 is separated from the upper and lower frame members 5 and 6 as a force transmission path in the vertical frame member 2 and cannot resist the axial force acting in the vertical direction, and contributes to improving the strength as an axial force member. Not done.

  For this reason, in the vertical frame member 2 of FIG. 5, only the axial force strength as a frame member in which the grooved steels 2a and 2b with lips are back to back can be expected. This is a square steel (box section steel) described below. It is inferior in strength compared to. Therefore, a box cross section is desirable as the vertical frame member 2 provided on both sides of the opening 1. Further, since the square steel has a web surface on four sides, it is good for attaching the lintel receiving material, and the covering material 14 in FIGS. 4 and 5 is not required.

  For this reason, the vertical frame material on both sides of openings such as windows or doors may be made of square steel, a typical example of which is a guide for designing thin, lightweight steel structures (Ministry of Land, Infrastructure, Transport and Tourism Supervised by Sogo Research Institute and Architectural Research Institute, edited by Japan Iron and Steel Federation, Gihodo Publishing, June 25, 2002). As this conventional form, there is an example in which a vertical frame member 2 having an assembly box cross section as shown in FIG. 6A and a vertical frame member 2 made of square steel as shown in FIG. 6B are used.

  In the example shown in the figure, the lip-shaped channel steels 2a, 2b are faced to face each other, the lips 25 are butted together, and the joining plate 26 is applied across the flanges 24 of the both lip-shaped channel steels 2a, 2b. A vertical frame member 2 having a box cross section is formed by placing a drill screw 8 on the two and integrating the lip-shaped channel steels 2a and 2b. FIG. 6E shows a vertical frame 2 made of square steel formed by rolling or bending.

Other conventional examples of square steel are disclosed in Japanese Patent Laid-Open No. 2001-152607 “Steel square steel for housing (FIG. 4)” and Japanese Patent Laid-Open No. 2001-329656 “Buckled cross-section thin plate member (FIG. 5). Japanese Patent Application No. 2001-329653 “Thin plate assembly material for construction (FIG. 6)” has been filed.

  The problems to be solved by the invention are as follows.

(1) In the vertical frame member 2 shown in FIGS. 4 and 5 that is most commonly used, it is necessary to join three channel steels including the covering member 14 with the drill screw 8, Assembly cost is a problem.

  In addition, the upper and lower frame members are arranged above and below the vertical frame member 2, but the upper and lower ends of the covering member 14 interfere with the flanges of the upper and lower frame members, so as shown in the figure. It is shorter than the vertical frame member 2, and therefore, especially for the design with respect to the axial force, although there are three shape steels, it is structurally inefficient that it must be regarded as two shape steels. It becomes member arrangement.

(2) In order to compensate for the drawbacks shown in (1), a vertical frame member 2 having a box cross section shown in FIG. 6B and a vertical frame member 2 having a box cross section shown in FIG. 6C have been proposed. In the vertical frame material 2 shown in FIG. 6 (b), the problem of assembling labor and cost is not completely solved, and a joining plate 26 as shown in the figure is separately required. It can be said that the tickling can be received only with steel, and the structural efficiency has improved. Furthermore, if the vertical frame member 2 shown in FIG. 6C is used, it is possible to eliminate assembling work.

  However, a new problem arises when these box cross-section vertical frame members 2 are used. That is, it is desirable that the mounting position of the hole-down hardware 16 on the vertical frame member 2 is closer to the center part (cross-sectional center of gravity) of the vertical frame member, and additional bending occurs in the vertical frame member 2 as the distance from the cross-sectional center of gravity increases. It will be.

  When the closed vertical frame member 2 shown in FIGS. 6 (b) and 6 (c) is used, the hole-down hardware 16 is separated from the cross-sectional center of gravity by a distance corresponding to half of the cross-section width of the section steel as shown in the figure. It will be joined at a shifted position. As a result, the plate thickness may have to be increased to reinforce the additional bending acting on the vertical frame member 2, and the use of the closed vertical frame member 2 is the best solution in terms of structure and economy. Absent.

(3) In the vertical frame member 2 made of square steel shown in FIG. 6C, drill screw joining between the shaped steels does not occur. However, in order to form square steel, larger equipment (joining equipment for making a closed cross section such as welding equipment and caulking equipment) is required compared to forming lip groove steel and light groove steel, The manufacturing cost of the shape steel increases.

  In view of the above problems, the present invention realizes the advantage of eliminating the need for a lintel support material by constituting a vertical frame material having a function corresponding to the shape steel of a box cross section, and also a conventional square steel The purpose is to provide a vertical frame material for a house such as a steel house which has solved the problem of unreasonableness in manufacturing and the eccentricity of the mounting position of the hole-down hardware due to the production of the vertical frame material at And
