Description

[Detailed Description of the Invention] Industrial Application Field This invention is a construction method for converting an existing frame, which is not a load-bearing structure, into a load-bearing wall, especially in an industrialized prefabricated house using a steel frame and panels. Regarding.

BACKGROUND ART For example, when adding a second floor to a one-story building, it is necessary to add a new load-bearing wall.

In such cases, conventionally, after removing exterior materials such as exterior wall panels, the frame of the part to be remodeled was removed and replaced with a new frame of the load-bearing wall structure. A different method is to weld the braces directly on site.

Problems to be Solved by the Invention However, in the conventional construction method described above, in which the frame is replaced, it is necessary to dismantle not only the exterior wall panels but also the interior materials. This has the disadvantage of increasing construction costs and lengthening the construction period.

On the other hand, with the method of welding braces on-site, it is difficult to ensure the quality of the on-site welding.

The present invention provides a construction method for adding load-bearing walls that eliminates the drawbacks of the conventional construction methods and allows construction to be carried out in a short period of time and at low cost.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a rectangular frame with left and right vertical frame members (3) (3) and upper and lower horizontal frame members (4) (4). In a framework (1) formed in a shape and provided with a center pillar (6) and/or a horizontal beam (7) across the approximate center of the frame body (5), the center pillar and/or the horizontal beam (7) are provided. The process of drilling a hole (14) to pass the brace (13) through the center of the crosspieces (6) and (7), and the brace (13) of the second tongue buckle, which is divided into two at the joint part.
through the hole (14) and interconnecting both the divided brace members (16) and (17), and a connecting member (
19) fixing (20) to the diagonal corners of the frame (1) using bolts (8) or anchor bolts (10) that interconnect each frame (1) and (2); It is characterized by:

In addition, in this invention, divided brace members (1
6) (17) The order of mutual connection and fixing of both ends to the frame (1) is not limited to the order described above, and may be performed before or after the order as appropriate.

Function According to the present invention, it is possible to remodel the wall into a load-bearing wall by simply drilling holes, removing bolts, tightening, etc. without removing the frame assembly (1).

EXAMPLE Next, the construction method of the present invention will be explained in accordance with its construction order.

In Fig. 5, (1) is the framework of the present invention that is to be remodeled into a load-bearing wall. and remove exterior members such as exterior wall panels and other girder materials. As shown in Figure 1, the frame assembly (1) to be modified consists of a pair of left and right vertical frames (3) made of metal channels (3) and a pair of upper and lower horizontal frames (4) made of channels as well. A rectangular frame body (5) is constituted by these. Inside this frame (5),
In the center of the left and right sides, a middle pillar (6) made of a pair of channel materials arranged back to back is installed across both horizontal frames (4) (4), and is further attached to the vertical frames (3) (3). Horizontal bars (7) (7) are attached between the central parts of the horizontal frames (4) (4).

After removing the exterior wall panels, etc., as shown in Figure 5, the vertical frames (3) (3) and the frames (2) (2) on both sides
There are a total of 8 bolts and nuts (8
)'(9), (8)(9)..., and the lower horizontal frame (
4) to the foundation (10)
Remove the nut (12) of I).

Thereafter, as shown in FIG. 6, a hole (14) for passing the buckle-type brace (13) as shown in FIG. 7 is opened in the center of the top and bottom of the middle pillar (6). This brace (13
) have opposite male screws (15) (
15) with a pair of screw rods (16) and (17), and both I
It consists of a joint (18) into which the j1 screws (15) (15) are screwed to connect these screw rods (16) (17). At the other end of each screw rod (16) (17), a joint plate 1- (19) (20) is attached, respectively.
Pre-welded. In addition, those joining plates (1
9) (20) each has a fixing piece (21) in the right angle direction.
(21) are integrally formed.

Next, as shown in FIG. 7, the brace (13) is separated by pulling out the longer screw rod (16) from the joint (18) and separating it from the other short male screw rod (17). Next, as shown in Fig. 1, insert the long male screw rod (16) that was cut off into the hole (14) opened in the middle pillar (6) through the horizontal bar (7).
Insert diagonally upward from the bottom. In this state, as shown in Figure 2, connect the joining plate 1 (19) to the flange (22) at the corner of the vertical frame (3) and the lower horizontal frame (4)
(22) Insert the fixing piece (21) between the vertical frame (3) side and reconnect it to the adjacent frame assembly (2) using the above-mentioned sip bolt (8) and nut (9). At the same time, fix it to the vertical frame (3). In addition, in the lower horizontal frame (4) (4),
Anchor bolts (11) protruding from the horizontal frame (4)
) to secure it by tightening the nut (12) that was previously removed. Note that bolt holes into which the bolts (8) and (11) are inserted are formed in advance in the fixing piece (21).

After fixing the longer male screw rod (16) as described above, fix the other short male screw rod (17) with its joint play (20) diagonally to the corner. Insert the corners of the upper horizontal frame (4) and vertical frame (3) and place them together (Figure 3). At this time, screw in the joint (18) to make it shorter and attach the joint (18) to the other male threaded rod (
16) to the male screw (15), and again connect this joint (I
8) and screw it onto the male screw (15) to connect. After or before this connection, the fixing piece (21) of the joining plate (20) is attached using bolts (8) and nuts (9) that bind the frameworks (1) and (2) together.

Finally, one diagonal brace (1
After installing 3), install the other brace (13) in the same way.

In addition, in the above, the hole (14) through which the brace (13) is passed is
) may be opened in the horizontal bar (7) or in both the middle pillar (6) and the horizontal bar (7).

Effects of the Invention As described above, according to the present invention, exterior materials such as exterior wall panels are removed, holes are made in the middle pillars and horizontal beams, braces are passed through the holes, and the frames are fixed to each other or to the foundation. Because it is a simple method of fixing the brace using bolts, compared to replacing the frame, there is no need to remove interior materials or perform other extensive dismantling of the vehicle, and it saves time in a short period of time. It has the effect of being able to be constructed at low cost. Furthermore, in the method of replacing the frame, the removed frame had to be disposed of as waste material, but the present invention does not have such inconveniences and can be implemented at lower cost. Furthermore, since welding is not performed on-site, there is less risk of quality problems such as welding accuracy, and there is no need for specialized workers such as welders.
