Description

[Detailed explanation of the invention] This invention is suitable for steel frame prefabricated houses, etc.
This invention relates to an improvement in the mounting structure of a corner cover that is installed to cover the corner of a pillar made of a metal cylinder.

Generally, in buildings such as steel prefabricated houses, the walls are constructed after the floors and columns are constructed. Recently, a construction method that combines an exterior wall panel with an exterior material and a corner cover has been adopted for wall construction because it is cost effective.

By the way, the corner cover used in this type of construction method is generally a single-piece molded product of the long corner cover itself with an L-shaped cross section using an exterior material such as fiber-mixed cement calcium silicate board, so-called Keikal board. is adopted. and,
When installing this corner cover body,
A corner cover body made of the above material is brought into contact with the outer corner of a column made of a metal cylinder with a rectangular cross section, and through holes are made in these using a tool such as a drill, and then only the through holes in the column are made into screw holes. The corner cover body is directly fixed to the column by screwing a mounting bolt into the screw hole through the through hole of the corner cover body.

However, the corner cover main body, which is made of exterior material such as Keikal board, is relatively fragile, so it is extremely difficult to directly install the corner cover main body, and the installation efficiency is poor. There were also problems with its durability.

Therefore, a highly rigid reinforcing plate such as a steel plate is superimposed and fixed on the back side of the corner cover main body to form a so-called lined corner cover. A side portion of the reinforcing plate partially protrudes from a side portion of the corner cover main body to serve as a mounting seat, and a mounting hole is provided in the mounting seat. A method is used for attaching and fixing the corner cover by abutting such a mounting seat against the column and screwing a mounting bolt into the column through the mounting hole.

However, for such attachment, it is necessary to use a tool such as a drill to make a through hole in the column, and then convert this through hole into a screw hole so that the above-mentioned attachment bolt can be screwed into it. That is, screws are still used, and a large number of holes must be drilled into the column made of a metal cylinder at the assembly site, which is not only time-consuming but also increases the rate of tool wear and damage.

On the other hand, for example, both ends of a beam made of a steel frame material having an E-shaped cross section or a foundation are attached to the above-mentioned column, but the means for attaching it is a fixing bolt with a large thread diameter and a large head diameter. Nuts are used. The above-mentioned nuts are fixed in advance to predetermined positions on the pillars at the manufacturing factory, and then transported to the site for assembly. Although a very large number of fixing bolts and nuts are required, their thread diameters are unified and only one type is required. Therefore, if the nuts mentioned above can be fixed in advance to the mounting positions of the corner cover body as well as the pillar beams and foundations, and the mounting seats of the reinforcing plate can be fastened with the fixing bolts mentioned above, there will be no negative impact on assembly man-hours, and parts management will be improved. The above is very convenient.

However, since the fixing bolt has a large thread diameter, the head diameter of the fixing bolt is also large.
For this reason, not only does the mounting seat require a large area, but also the head of the fixing bolt protrudes largely from the side of the corner cover main body, resulting in a large distance from other adjacent outer wall panels. The so-called joint width becomes large, which not only makes the appearance unsightly, but also causes problems in that it takes time and effort to fill in the joints.

Therefore, when attaching a corner cover to a pillar, which is made by lining and reinforcing a corner cover body made of a relatively brittle material with a reinforcing plate made of a metal plate, nuts and fixing bolts used for attaching beams and foundations are required. It would be convenient if the joint width could be made smaller while still being used as is.

This idea was created in view of the above circumstances, and its purpose is to strengthen the corner cover pillar by lining and reinforcing the corner cover main body made of a relatively brittle material with a reinforcing plate made of a metal plate. To install it, screw a fixing bolt with a screw hole with a small thread diameter along the axis of the nut fixed to the column, and place a mounting seat protruding from the side of the corner cover main body of the reinforcing plate onto this fixing bolt. By inserting small screws into the screw holes of the fixing bolts through the mounting holes of this mounting seat and attaching and fixing the corner cover to the pillar, the mounting strength of the corner cover body is improved and it is also possible to attach beams or foundations. The present invention aims to provide a mounting structure for a corner cover that can be mounted to a column by reusing the fixing bolts and nuts that are the parts of the corner cover, and that has an extremely small joint width.

This invention will be explained below based on an embodiment shown in the drawings. FIG. 1 and FIG. 2 show the structure around a pillar of a prefabricated house, etc. In the figures, 1 is a pillar made of a metal cylinder made of iron and having a rectangular cross section. An outer wall panel 3a having an exterior material 2a is attached to one outer surface of the pillar 1.
Similarly, an outer wall panel 3b provided with an exterior material 2b is attached to the other outer surface. Further, a corner cover 4 is attached to the outer corner of the pillar 1, and the corner cover 4 and the exterior panel 3
The combination of a and 3b constitutes a wall portion of a prefabricated house or the like. And this corner cover 4
The detailed mounting structure is shown in FIGS. 3 and 4. First, to explain this corner cover 4, 5 in the figure is a cross section L integrally formed with an exterior material made of a relatively brittle material such as fiber-mixed cement calcium silicate board, so-called silica board.
The corner cover main body 5 is shaped like a letter, and has a length corresponding to the length of the pillar 1. And this corner cover body 5
A reinforcing plate 6 formed of a metal member such as an iron plate and having an L-shaped cross section is overlaid on the entire inner surface of the reinforcing plate 6 and fixed using an adhesive or the like. That is, the corner cover 4 is composed of a corner cover body 5 and a reinforcing plate 6 that lines and reinforces the corner cover body 5. The side part of the reinforcing plate 6 is the corner cover main body 5.
It protrudes laterally from the side part of and forms a mounting seat 6a. A plurality of mounting holes 7 are formed in the mounting seat 6a at predetermined intervals. On the other hand, a plurality of through holes 8 are provided in a portion of the column 1 facing the mounting hole 7, and a nut 9 having a screw hole 9a whose axis coincides with the through holes 8 is fixed to the inner surface side of the column 1. . This nut 9 is also fixed in advance at another position in order to attach and fix a beam, a base, etc. (not shown here) to the column 1. Then, the fixing bolt 10 is screwed into the screw hole 9a of the nut 9 through all the through holes 8. That is, the fixing bolt 10 has a large head diameter, and although it is simply screwed in here, it is used in other parts for attaching and fixing beams and foundations to columns. This fixing bolt 10 has a screw hole 10a with a small thread diameter along its axis.

Therefore, when installing the corner cover 4, the mounting seat 6a is brought into contact with the head surface of the fixing bolt 10, and the mounting hole provided in the mounting seat 6a is inserted into the screw hole 10a provided in the fixing bolt 10. 7
communicate. From this mounting hole 7 to the screw hole 10
Insert the machine screw 11 into a. This machine screw 11 is a commonly used screw with a small head diameter. Therefore, the corner cover 4 is attached and fixed to the pillar 1, and most of the heads of the fixing bolts 10 are hidden by the mounting seats 6a. Finally, exterior wall panel 3
a, 3b are installed to hide the remaining head portions of the fixing bolts 10, and a joint material is filled between these and the corner cover main body 5 to hide the heads of the machine screws 11, the wall construction can be completed. will end.

In the above embodiment, the mounting seat 6a is provided along the longitudinal direction of the reinforcing plate 6, but the mounting seat 6a is not limited to this, and may be made to protrude only around the mounting hole 7. It goes without saying that various other modifications can be made without departing from the gist of the invention.

As explained above, according to this invention, a through hole is provided in a pillar made of a metal cylindrical body, and a nut is fixed to the inner surface of the pillar so that the through hole and the screw hole communicate with each other, and the A fixing bolt having a screw hole with a small thread diameter is screwed into the nut along the axis, and a corner cover main body made of a relatively brittle material is lined with a reinforcing plate made of a metal plate to form a corner cover, and the reinforcing plate Place the mounting seat protruding from the side of the corner cover body into contact with the head of the fixing bolt, and screw the machine screw into the screw hole of the fixing bolt through the mounting hole provided in the mounting seat to attach the corner cover. It is attached to a pillar via a fixing bolt. Therefore, unlike conventional methods in which the corner cover body itself, which is made of a relatively brittle material, is attached directly to the pillar, there is no need to pay close attention when attaching the corner cover, and there is no need to pay close attention to the corner cover body. Since no drilling is required, it is resistant to external forces such as wind and rain after installation and has excellent durability. Furthermore, since the corner covers are installed by reusing the nuts and fixing bolts used to attach beams and foundations, parts management is easy, and the heads of machine screws, whose diameter is much smaller than the head diameter of the fixing bolts, are used to attach the corner covers. Since the section is interposed between adjacent panels, the joint width can be made extremely small, which helps improve the aesthetic appearance.
