Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique suitable for constructing an outer wall of a low-rise general building, and particularly to an office, a warehouse,
The present invention relates to a technique for constructing a metal outer wall generally used as an outer wall of a factory or the like.

[0002]

2. Description of the Related Art Conventionally, when building a low-rise building such as an office, a warehouse, or a factory to construct a metal outer wall,
Base steel for outer wall (hereinafter referred to as "frame member", or
Metal fittings (hereinafter called "cat")
, And the furring was attached to the cat, and metal outer walls were fixed to the furring by screwing them one by one.

In this conventional method, it is necessary to machine a bolt hole for attaching a cat on the furring edge side, and since the metal wall material is screwed from the outside of the building to the furring edge, the outer periphery of the building is It was necessary to assemble scaffolding to perform these tasks. However, in the above method of constructing a metal outer wall, it is troublesome to carry in materials on a scaffold that is a high place, and due to work restrictions, the number of people working at one time is limited, so There was a problem that it took time to complete the construction. Further, since the work is performed on a high scaffold, accidents such as dropping of materials may occur, which requires a great deal of safety attention.

By the way, in the case of a large high-rise building, the scaffolding covering the outer periphery of the building cannot be easily formed. Therefore, the panel construction method called the curtain wall construction method is actually used. In this method, a steel structure is assembled by welding to form a frame structure (simply referred to as a frame), and a curtain formed by bolting (also referred to as screwing) a material such as metal, stone, or concrete to the frame structure. The wall is manufactured and attached to the steel frame assembled at the construction site by applying joining means such as welding or bolting.

In this curtain wall construction method, mounting hardware is provided on the main body steel frame side and the curtain wall side in advance, and both mounting hardware are joined on site. The curtain wall method is often used for large-scale construction, but it is manufactured in factories because it is strong in strength, excellent in design, and stable in quality. Therefore, it is manufactured in a size that can be transported from the factory to the construction site and installed on site.

[0006] In the installation work on site, the curtain wall can be lifted with a crane or the like to be aligned with a predetermined position and fixed by a worker in the building. Therefore, a scaffold is constructed around the building. You don't have to. However, there are the following two problems in using this curtain wall method as it is for the construction of outer walls of low-rise buildings.

First, although it is not necessary to use a wall body having a strong frame structure such as a curtain wall for the outer wall of a low-rise building, it is necessary to install the curtain wall in order to install the curtain wall. The columns and beams on the side of the building to be fixed must be made stronger than necessary. Secondly, the curtain wall is manufactured by a factory in order to manufacture it with stable quality because it requires skill such as welding and has a process that is greatly influenced by the working environment. The size of the wall is limited because it is transported from the factory, and as a result, compared to the method conventionally used in low-rise buildings, that is, the method of directly attaching a metal wall to the furring strip, the wall surface that can be constructed at once Area does not change much.

Certainly, the curtain wall construction method has an advantage that the scaffolding is not required and the scaffolding can be removed early in the construction process, but on the other hand, the work of hoisting the curtain wall with a crane and attaching it to the wall surface is frequently performed. There is no need to change the overall construction period. Therefore, in the small-sized low-rise buildings, the above-mentioned construction method of screwing the metal wall body to the furring strip by using the outer peripheral scaffold is still adopted at present.

[0009]

By the way, even in low-rise buildings, if it is possible to utilize a panel construction method for integrally attaching outer walls, it is considered that the work can be greatly simplified. However, as mentioned above, the conventional curtain wall construction method cannot be applied directly to the construction of low-rise buildings.

The present invention solves such a problem and enables a panel construction method conforming to the curtain wall construction method even in a small low-rise building to simplify the outer wall construction work, thereby reducing the number of steps and the work. The purpose is to ensure the above safety.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be sequentially described with reference to FIGS. An example of the frame structure applied to the outer wall panel of the present invention is shown in FIG. The frame structure 5 includes steel frame members 1a, 1b, 1c, etc., adjusted to have a predetermined length, and a metal fitting 2,
It is assembled by joining with 3 and 4.

The frame members 1a, 1b, 1c made of steel are formed by cutting a steel material such as a lip channel steel or a square steel pipe into a predetermined length.
It is a painted member. Also, the joining hardware 2, 3,
4 is used for joining the steel frame members 1a, 1b, 1c to each other. Depending on the shape of the joining portion, L-shaped,
There are three types of metal fittings, T-shaped and cross. The details of the joining hardware 2, 3, 4 will be described later.

The frame members 1a, 1b, 1c and the metal joint 2,
3, 4 can be fitted into each other, and after confirming the dimensional accuracy, they are temporarily fixed with screws to form the frame structure 5. Then, a metal wall material is appropriately fixed to the frame structure 5 by screwing or the like to complete the outer wall panel. As the metal wall material, it is possible to use a metal material or the like that has been formed into various cross-sectional shapes by roll forming or the like. Since the frame structure 5 is fixed to the metal wall material and integrated as described above, the temporarily fixed joining metal parts 2, 3 and 4 do not come off, and a strong outer wall panel can be integrally formed. Of.

Further, the frame member 1b in the height direction of FIG.
As the frame member corresponding to 1c, a long frame member in which the both are integrated can be used, and the frame structure can be configured by passing the metal members 3 and 4 inside. This configuration is preferable because it is possible to reduce the number of frame members to be prepared and to eliminate the distortion caused by connecting the frame members in the height direction.

Further, as shown in FIG. 2, by assembling the frame 5 by combining the required frame members 1a, 1b, 1c and the metal fittings 2, 3, 4, the opening 6 serving as an entrance and exit can be easily formed. be able to. Although FIG. 2 shows an example in which the opening for the entrance and exit is formed, it is clear that the openings such as windows and doors can be freely formed. Next, regarding the joining metal article which is a feature of the present invention, FIGS.
It will be explained based on. 3 is an L-shape, and FIG. 4 is a T.
FIG. 5 shows a preferred example of a cross-shaped joining metal article.

First, in the L-shaped metal fitting 2 of FIG. 3 (a), a lip groove member 10 obtained by bending an iron plate of a required length into a lip groove shape is cut into a predetermined length, and assembled at a right angle and welded. Etc. The L-shaped joining hardware 2 is used for the outer peripheral corners of the frame and the like (see FIG. 1). Here, adjust the inner dimensions of the L-shaped joining hardware 2 and the outer dimensions of the frame members 1a, 1b, 1c,
Adjust the dimensions so that they can be fitted and joined together.

As shown in FIG. 3 (b), one iron plate may be cut, bent and deformed, then bent 90 ° and welded to form the L-shaped metal fitting 2. Next, FIG. 4A shows a preferred example of the T-shaped metal fitting 3 in which the lip channel member 10 is combined in a T-shape. This T
In the case of the letter shape, the frame members 1a, 1b,
By fitting and fixing 1c, it is possible to apply it to the portion of the outer periphery of the frame that is the intersection of the vertical furring strip and the horizontal furring strip.

As shown in FIG. 4 (b), the T-shaped metal fitting 3 is formed by a lip groove member 10 and a groove member 11 formed by bending an iron plate, and the groove member 11 is formed as a horizontal furring strip. If it is used for joining, the frame member of the lateral furring strip can be simply inserted into the groove of the groove-shaped member 11 instead of being inserted, and simply fitted and joined. Therefore, workability can be significantly improved.

In the case of the above T-shape, instead of inserting from two sides and fitting, it is also possible to insert and join one frame member. On the contrary, a stopper such as a protrusion may be provided on the inner surface side of the metal joint so as to prevent the inserted frame member from penetrating (not shown). Next, FIG. 5 shows a preferred example of the cross-shaped metal fitting 4 having a cross shape. The cross-shaped metal fitting 4 shown in FIG.
Channel-shaped members 11 are welded to both the lip side and the opposite side of the same at right angles so that the grooves are oriented in the same direction. This cross-joint metal fitting 4 is fitted with frame members from both ends of the lip groove-shaped member 10 to be fixed, and also the respective groove-shaped members.
Fitting the frame member to 11 also enables cross-shaped joining. It goes without saying that a lip channel member may be used instead of the channel member 11 of FIG.

This cross-joint metal fitting 4 is applied to a position where the vertical furring strip and the horizontal furring strip cross each other except the outer periphery of the frame (FIG. 1).
reference). The features of inserting the frame member of the vertical furring strip into the lip groove-shaped member, dropping the frame member of the horizontal furring strip into the groove-shaped member, and joining the frame member are already described in the T-joint metal fitting 3 of FIG. As described,
The description here is omitted.

By the way, in the above description, an example in which the frame member is inserted and fitted inside the metal joint has been described as a preferred example. For example, as shown in FIG.
This is an example in which the frame members 1a and 1c are inserted and joined to the L-shaped joint hardware 2. However, as shown in FIG. 6 (b), it is clear that the same effect can be obtained even if the frame members 1a and 1c are fitted and joined to the outside of the L-shaped metal fitting 2.

By adopting the outer wall panel assembling method of the present invention and assembling the outer wall panel by using each of the above-mentioned joining metal parts, the frame structure can be assembled very easily on the site of the construction site. Further, by appropriately screwing a metal wall material to the assembled frame, an extremely strong outer wall panel can be easily manufactured. Then, the completed outer wall panel can be lifted up as it is by a crane or the like and attached to a pillar or windproof beam of a building to immediately complete the outer wall.

In the above description, the convenience of the work is prioritized and the frame member and the metal fitting are joined by simply fitting them together, but they are further reinforced by screwing them together. It is also possible to make a stronger frame structure. In addition, since there is no need for transportation from the factory, it is possible to increase the size of the outer wall panel that is manufactured on-site and reduce the panel mounting work. In some cases, it is possible to fabricate an outer wall panel according to the size of the wall surface of the building and install it on one wall surface of the building as one outer wall panel.

When the outer wall panel of the present invention is attached to a pillar or windproof beam of a building, it may be welded or bolted. In particular, at least a part of the frame member constituting the outer wall panel is a lip channel steel. And when fixed to a windproof beam having a flange, the clip shown in FIG.
It is preferable to apply and attach 15L and 15R. The clips 15L, 15R are made of channel-shaped three-sided shaped steel material. Since they are fixed by engaging with the lip portion of the frame member, which is a lip channel-shaped steel not shown here, the clips 15L, 15R have two parallel surfaces. A claw portion 18 formed at either one of the ends, a fitting slit portion 17 formed by cutting at an opposing position of the two surfaces and fitted to the flange while straddling the flange, and the remaining one surface. The flange is provided with a bolt 16a (Fig. 8).
And a bolt hole 16b for connecting the frame member and the wind resistant beam by engaging the lip member and the claw portion by pressing the frame member via the flange. To do. Note that right (R) and left (L) are prepared according to the direction in which the frame member has the lip.

In FIG. 8, the clip member 15R for the right side (R) is applied to the frame member 1c made of lip channel steel and the flange 19a.
It shows a state of being joined to a wind-resistant beam (in this case, an H-shaped steel member) 19 having. As shown in the drawing, the flange 19 is pressed by the bolt 16a, and at the same time, the frame member 1c is pressed through the flange 19 so that the lip portion of the flange 19 and the claw of the clip 15R of the present invention are engaged and fixed. .

It is sufficient for the slit height of the fitting slit portion 17 to be about 10 to 20 mm higher than the height of the flange on the windproof beam side. The height of the clip itself is preferably about twice the height of the slit. It is sufficient that the claw portion 18 is sufficiently caught by the engaging lip of the grooved steel, and it is preferably about 15 mm.
