Description

[Detailed description of the invention] (Industrial application field) This invention relates to the wall frame of a steel-framed prefabricated house, etc.

(Prior Art) Wall frames of steel prefabricated houses and the like are reinforced by stretching braces.

(Problem that the invention aims to solve) When the wall frame is large, a central column may be placed in the center to reinforce it to give it strength. If the wall frame is made of channel steel, welding can cause distortions. This distortion needs to be adjusted with the turnbuckles of the brace. However, when trying to further strengthen a wall frame with central columns with braces,
This middle pillar becomes an obstacle and it is not possible to install the brace. Furthermore, if the cross section of the brace is exposed, the appearance will be poor.

The purpose of the wall frame of the present invention is to solve these problems.

(Means for solving the problem) The wall frame of the present invention has a rectangular frame formed by combining an upper chord member, a lower chord member, and a pair of vertical members made of channel steel, and Two middle pillars made of channel steel are arranged back to back between the upper chord member and the lower chord member in the central part of the vertical direction, and between the left and right vertical members and the middle pillar in the central part of the vertical direction. This is a wall assembly with horizontal beams arranged on the wall assembly, two braces each having a turnbuckle attached to adjust the dimensional accuracy of the wall assembly are arranged in a crossed manner on the wall assembly, and the two braces are Each end of the brace is fixed to each of the four corners of the wall frame, and the cross portion of the two braces is inserted into a hole formed in the center column.

(Function) Two braces are stretched across the inside of the wall frame, and the cross portions of the two braces are placed back to back in the center of the frame that constitutes the wall frame. It is inserted through a through hole formed in the middle column made of channel steel. Therefore, even in a relatively large wall frame with a center column, the dimensional accuracy is improved because the turnbuckle-equipped brace is used, and the appearance can be improved because the cross section is hidden by the center column.

(Example) The present invention will be described below based on an example shown in the drawings. Wall frame assembly A combines an upper chord member 1a and a lower chord member 1b made of channel steel, and a pair of vertical members 2a and 2b into a rectangular frame, and furthermore, has two central members in the lateral center of the frame. The pillars 3, 3 are arranged back to back (both grooves are oriented toward the vertical members 2a, 2b). The intersection points 5 and 5 and 6 and 6 of the upper chord member 1a, the lower chord member 1b, and the vertical members 2a, 2b are diagonally crossed in each through hole 4, 4 provided in the center of the middle pillars 3, 3. The cross portions of the two braces 7 and 8 that are stretched are inserted through them.

Brace mounting plates 10 and 10 welded to the intersections of b (four corners of the wall frame) are attached to the middle of braces 7 and 8, and turnbuckles 11 and 11 are used to adjust the length of these braces, respectively. This is a horizontal beam that connects the left and right vertical members 2a, 2b and the middle pillars 3,3. Brace 7, 8 and brace mounting plate 9
...and are connected by welding.

In the drawing, the middle pillars 3, 3 are made by placing two channel steel pieces back to back at an appropriate interval, and forming the upper chord member 1.
The center portions of the lower chord member 1b and the lower chord member 1b are connected. In addition, the upper chord member 1a, the lower chord member 1b, and the vertical members 2a, 2b
Both are assembled into a rectangular frame using channel steel.

(Effect of the invention) In the center of a rectangular frame formed by combining an upper chord member, a lower chord member, and a pair of vertical members made of channel steel, the upper chord member and the lower chord member are connected to each other. Because it is a wall frame with two central pillars placed back to back, even if it is a wide wall frame,
Because these two central pillars are provided, the strength in the vertical direction is high.

Since the two middle pillars are arranged back to back with the grooves facing outward, there is no problem of air being trapped between these middle pillars. Since air is not trapped, moisture does not accumulate inside and condensation does not occur.

In addition, when constructing a wall, usually multiple wall frames are installed in a row, and in this case, the vertical members of the adjacent wall frames are placed back to back (here, the upper chord member and the lower chord member are connected back to back). (And the pair of vertical members both have their grooves facing inward of the frame.) They will be erected. Therefore, since the wall frame of the present invention has two central pillars placed back to back in the center of the frame,
Build a wall that has the same structure at the joints of wall frames and the center of each wall frame, and has uniform strength throughout (no buckling in the center of the wall frame). be able to.

As described above, even in a wall frame assembly in which the strength is increased by disposing a center column in the center of the frame, distortion occurs in the connection of each component (distortion is likely to occur due to welding). Therefore, in order to adjust this distortion and obtain the desired dimensional accuracy, it is necessary to connect the opposing corners of the frame with a brace with a turnbuckle. The central pillar of the book becomes a nuisance. However, since each of these two center pillars has a through hole formed at the same position, by inserting a brace into this hole, it is possible to connect the opposing corners of the frame with the brace without any support. can. Moreover, since the brace can be located at the center of the frame in the thickness direction, it is possible to perform appropriate distortion adjustment, and the brace does not protrude from the outer surface (both sides) of the frame. For example, it does not interfere with the installation of wall materials, etc. Furthermore, since the intersection of the braces will be located within the center column, the appearance will not be spoiled.
