Abstract

PROBLEM TO BE SOLVED: To prevent deformation of a metal beam member when supporting a plate member without changing a production line. SOLUTION: A horizontal extension part 43 on which a steel ceiling joist 30 is mounted is cut and formed at a stiffener 40. The steel ceiling joist 30 is mounted on the horizontal extension part 43. As the steel ceiling joist 30 is supported by a horizontal extension part 43, the other side wall part 43 will not be lowered by the weight of a ceiling plate member 15. By cutting a part of the stiffener 40 to form the horizontal extension part 43 and by mounting the steel ceiling joint 30 on the horizontal extension part 43, deformation of the steel ceiling joint 30 when supporting the ceiling plate member 15 can be prevented almost without changing a production line for assembly of a ceiling part at a plant and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a metal beam.

[0002]

2. Description of the Related Art Conventionally, there are unit-type buildings constructed by combining several building units manufactured in a factory, and buildings by a conventional construction method in which all processes are performed at a construction site. In each of these buildings, wooden beams are used as beams such as a ceiling margin supporting the ceiling panel and a floor joist supporting the floor panel. However, in recent years, deforestation has also begun to be restricted to protect the environment.
It is becoming difficult to use wooden square beams as beams for ceiling margins and floor joists. In view of this, instead of a wooden square bar, a thin iron square pipe (hereinafter referred to as a light iron square pipe) which has been reduced in weight to approximately the same weight as the wooden square bar has been attempted.

[0003]

However, light iron square pipes have a lower rigidity than wooden timbers, and therefore, similar to conventional wooden timbers, light iron square pipes are used as fixing members, which are building bodies of buildings. When one of the two side walls is attached to support a surface material such as a ceiling surface material, the weight of the surface material opposes one of the side walls of the light iron square pipe attached to the skeleton. In this case, the other side wall portion is lowered, and the light iron square pipe is deformed into a parallelogram shape, so that there is a problem that the face material cannot be supported. On the other hand, it is also conceivable to attach a separate support member for supporting a light iron square pipe to a fixing member, which is different from the conventional one, to support the light iron square pipe so as not to be deformed (Japanese Patent Laid-Open No. 9-78748). However, there has also been a problem that a part which has not been used conventionally, such as a support material, must be attached, and a production line for assembling a ceiling portion in a factory or the like must be changed.

[0004] An object of the present invention is to provide a metal beam mounting structure capable of preventing deformation of a metal beam composed of a light iron square pipe or the like when supporting a face material without changing a production line. It is in.

[0005]

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to the drawings.
2) of a metal beam material including a fixing member (for example, stiffener 40) attached to the beam, and a prismatic metal beam material (for example, iron ceiling edge 30) attached to the fixing member. The mounting structure is characterized in that a horizontally extending portion 43 is cut and raised in a fixing member, and a metal beam is placed on the horizontally extending portion 43. The metal beam material is, for example, a light iron material, that is, a thin iron beam material that is reduced in weight to approximately the same weight as a wooden square material.

[0006] Such a metal beam is used, for example, in a framework of a building unit constituting a unit-type building.
Attach to upper and lower beams via fixing members.

By forming a horizontal extension on the fixing member and placing a metal beam on the horizontal extension, for example,
When one of the two opposing side walls of the metal beam is attached to the fixing member, the metal beam is supported not only at the attachment point but also at the horizontal extension, so that the other side wall is provided. The portion does not lower due to the weight of the surface material such as the ceiling surface material, and the surface material such as the ceiling surface material 17 can be reliably supported at a predetermined position without deforming the metal beam material.

In addition, since the horizontal extending portion is formed by cutting and raising a part of the fixing member, it is only necessary to add a cutting and raising step in a manufacturing line of the fixing member, and the metal member is formed on the fixing member. Compared to the case where a separate supporting material to be supported is attached by welding etc. and the metal beam material is supported so as not to be deformed, there is almost no need to change the production line for performing the assembly work of the ceiling part in factories, etc. The work of assembling the ceiling becomes easy.

Further, it is preferable that a vertical extension portion 44, which is orthogonal to a direction toward the distal end, is continuously provided at a tip of the horizontal extension portion 43. If a vertical extension is formed at the tip of the horizontal extension, the metal beam can be sandwiched between the vertical extension and the fixing member in the horizontal direction. There is no need for an operator to hold down the metal beam when mounting, and the work of mounting the metal beam is facilitated.

Further, the engaging portion 3 engages with the vertically extending portion 44 of the fixing member and the side wall portion of the two side wall portions 31 and 32 of the metal beam material which is opposed to the vertically extending portion 44.
It is preferable to provide 3, 44A. By providing an engaging portion that engages with a side wall portion of the fixing member that is opposed to the vertical extension of the metal member and the vertical extension of the metal beam, the metal beam can be fixed to the vertical extension. As a result, the holding of the metal beam material is further strengthened.

Preferably, the vertical extension 44 of the fixing member and the engaging portions formed on the side wall of the metal beam are a convex portion 44A and a concave portion 33 which engage with each other. If the vertically extending portion and the engaging portion formed on the side wall portion of the metal beam material are a convex portion and a concave portion that engage with each other,
Since the metal beam or the like can be easily formed by extrusion or the like, the production of the metal beam or the like is simplified, and the work of attaching the metal beam is also facilitated.

Further, it is preferable to form a contact portion 45 with which the end of the metal beam contacts the fixing member. If a contact part is formed on the fixing member, when installing a metal beam,
It is only necessary to push the metal beam until it hits the abutting part, and there is no need to position the metal beam in the direction along the longitudinal direction. This also makes the assembly of the ceiling part easier. .

It is desirable that the contact portion 45 is formed continuously with the horizontal extension portion 43. If the contact portion is formed continuously with the horizontal extension portion, the contact portion and the horizontal extension portion are formed only by cutting and raising a part, so that the manufacturing of the fixing member is facilitated.

Furthermore, it is desirable to attach an auxiliary member 17 to the lower surface of the metal beam along the longitudinal direction of the metal beam. If you attach an auxiliary member to the lower surface of the metal beam,
Warpage, bending, and the like generated in the metal beam due to gravity or the like can be prevented, and deformation of the entire metal beam can be prevented.

And a vertically extending portion 44 which is orthogonal to the direction toward the front end and is formed continuously with the horizontal extending portion 43. In addition, a convex portion 44A, which is an engaging portion that is processed by a press machine or the like and is protruded toward the planar portion 42 side, is provided substantially at the center of the vertical extension portion 44 of the stiffener 40 in the vertical direction.
Are formed.

The iron ceiling ridge 30 is a thin iron ceiling ridge made of light iron, that is, light in weight about the same as a wooden square bar. Specifically, the iron ceiling ridge 30 is formed in the shape of a rectangular tube, and approximately at the center in the height direction of the two side walls 31 and 32, is continuous along the longitudinal direction of the iron ceiling ridge 30, and , A concave portion 33 which is an engaging portion depressed from the surface thereof is formed. And, the concave portion 33 of the iron ceiling edge 30
And the convex portion 44A of the vertical extension portion 44 of the stiffener 40 are engaged with each other, and are fixed to the planar portion 42 of the stiffener 40 by plug welding.

Below the planar portion 42 of the stiffener 40, a square member 16 formed to have substantially the same length as the upper beam 12 and fixing the ceiling panel 15 arranged along the upper beam 12 is provided. Are located. Further, on the lower surface of the iron ceiling edge 30, an auxiliary member 17 having the same width as that of the lower surface and along the longitudinal direction of the iron ceiling edge 30 is attached.

In this embodiment, the ceiling of the frame 10 of the building unit 1 is formed as follows. First, a part of the main body 41 of the stiffener 40 is cut and raised to form a place where the steel ceiling ridge 30 is arranged. Specifically, as shown in FIG. 4, a cut is made vertically in a part of the main body 41, a cut is made horizontally by cutting both ends of the cut, and the cut is made so as to be orthogonal to the main body 41, and the contact portion 45 is bent. Form. Next, as shown in FIG. 5, a cut is made by a predetermined dimension from the lower edge of the cut and raised portion, and a portion on the side of the main body 41 is horizontally bent from the cut to form a horizontal extension 43. Then, as shown in FIG. 6, a portion outside a portion cut upward from the lower edge is bent along the cut vertical direction to form a vertical extension portion 44.
A substantially vertical center of the vertically extending portion 44 is processed by a press or the like to form a convex portion 44A (FIG. 3).

The stiffener 40 thus formed is
Is disposed on the inner surface of the upper beam 12, and the planar portion 42 is attached by welding or the like in a state of protruding from the inner edge of the upper beam 12. After the attachment, the end of the iron ceiling ridge 30 is pushed horizontally until the end portion of the iron ceiling ridge 30 abuts on the contact portion 45 while the recess 33 of the iron ceiling ridge 30 is engaged with the projection 44A of the vertical extension portion 44. Then, the iron ceiling edge 30 and the planar portion 42 are overlapped and fixed by plug welding. Next, the square member 16 and the auxiliary member 17 are attached below the planar portion 42 of the stiffener 40 and the iron ceiling edge 30, and the ceiling member 15 is fixed to the square member 16 and the auxiliary member 17 by nailing or the like.

According to this embodiment, the following effects can be obtained. A horizontal extension 43 is formed in the stiffener 40, and the iron ceiling ridge 30 is placed on the horizontal extension 43, so that the iron ceiling ridge 30 opposes the iron ceiling ridge 30.
When one of the side wall portions 31 and 32 is attached to the stiffener 40, the horizontal extension portion 43 supports the iron ceiling edge 30 so that the bottom surface of the iron ceiling edge 30 is the ceiling surface. Since the other side wall 32 does not fall down due to the weight of the member 15, the deformation of the iron ceiling ridge 30 can be prevented, and the surface member such as the ceiling member 15 can be securely placed at a predetermined position. I can support it.

In addition, the horizontal extension 43 is provided with the stiffener 4.
Since the stiffener 40 is formed by cutting and raising a part of the stiffener 40, it is only necessary to add a cutting and raising process in the stiffener 40 manufacturing line. Compared with a case where the ceiling margin 30 is supported so as not to be deformed, the production line for performing the assembly operation of the ceiling portion in a factory or the like hardly needs to be changed, and the assembly operation of the ceiling portion can be easily performed.

The vertical extension 44 is formed at the end of the horizontal extension 43 so that the steel ceiling ridge 30 can be sandwiched between the vertical extension 44 and the stiffener 40 in the horizontal direction. When attaching the iron ceiling ridge 30 by welding or the like, there is no need for an operator to perform welding or the like while pressing the iron ceiling ridge 30, and the work of attaching the iron ceiling ridge 30 can be facilitated.

Further, the vertical extension 44 of the stiffener 40
In addition, since the convex portion 44A and the concave portion 33 that engage with each other are formed on the side wall portion 32 disposed opposite to the vertical extension portion 44 of the iron ceiling ridge 30, the iron ceiling ridge 30 can be fixed more firmly. In addition, the iron ceiling ridge 30 can be easily formed by extrusion molding or the like, and the manufacture of the iron ceiling ridge 30 can be facilitated, and the mounting work of the iron ceiling ridge 30 can be facilitated.

Further, by forming the contact portion 45 on the stiffener 40, when the iron ceiling edge 30 is installed, the iron ceiling edge 30 may be pushed in until it hits the contact portion 45. The positioning in the direction along the longitudinal direction of 30 can be easily performed. In addition, the vertical positioning of the iron ceiling ridge 30 can be easily performed only by placing the iron ceiling ridge 30 on the horizontal extension portion 43. From these points, the assembling work of the ceiling portion can be further facilitated. In addition, since the contact portion 45 is formed continuously with the horizontal extension portion 43, the contact portion 45 and the horizontal extension portion 43 can be formed only by cutting and raising a part of the stiffener 40. Therefore, the stiffener 40 can be easily manufactured.

Further, the auxiliary member 17 is attached to the lower surface of the iron ceiling ridge 30 so that the iron ceiling ridge 3 is attached.
It is possible to prevent warping or bending of the iron ceiling edge 30 due to gravity or the like such that the middle portion in the longitudinal direction of the iron ceiling 30 is lowered, and to prevent deformation of the entire iron ceiling edge 30.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and also includes the following modifications.
For example, in the above-described embodiment, the auxiliary member 17 is attached to the lower surface of the iron ceiling edge 30. However, the auxiliary member 17 may not be attached. In other words, when the length of the iron ceiling edge 30 is short, gravity or the like that lowers the middle portion in the longitudinal direction of the iron ceiling edge 30 is hardly applied, so that the auxiliary member 17 does not need to be attached, If a reinforcing groove having a substantially triangular cross section is provided along the longitudinal direction on the lower surface of the iron ceiling edge 30, the strength of the iron ceiling edge 30 in the horizontal direction can be further increased. 17 does not have to be attached.

In the above embodiment, the stiffener 40
Although the contact part 45 with which the edge part of the iron ceiling ridge 30 abuts is formed, it may not be formed, for example,
As shown in FIG. 7, the iron ceiling ridge 30 may be supported by the horizontal extension 43 and the vertical extension 44. However, the contact part 4
When the iron ceiling ridge 30 is installed, the iron ceiling ridge 30 may be pushed into the iron ceiling ridge 30 until it hits the contact portion 45 when the iron ceiling ridge 30 is installed, and the iron ceiling ridge 30 is positioned in the longitudinal direction. Is easily performed, which is preferable in that the work of assembling the ceiling portion can be further facilitated. Further, in the above embodiment, the contact portion 45 is
Are formed continuously, but may not be formed continuously.

Further, in the above embodiment, the recess 33 is formed in the iron ceiling ridge 30, and the projection 44 is formed in the vertical extension 44.
Although A is formed, it may be reversed, and there is no need for such engaging portions that engage with each other. Further, in the above-described embodiment, the recesses 33 are formed in the two side walls 31 and 32 of the iron ceiling ridge 30, however, the present invention is not limited to this. What is necessary is just to form on the side which opposes the part 44. However, when the concave portions 33 are formed in the two side wall portions 31 and 32, respectively, when the concave portions 33 of the iron ceiling ridge 30 are engaged with the convex portions 44A of the vertical extension portions 44, the iron ceiling ridges are formed. This is preferable because it is not necessary to consider the installation position of the steel ceiling 30 and the work of mounting the iron ceiling ridge 30 can be facilitated.

Further, in the above embodiment, the horizontal extension portion 4
Although the vertical extension portion 44 is provided at the tip of 3, it is not necessary to provide it. However, when the vertical extension portion 44 is provided, the iron ceiling edge 30 can be sandwiched in the horizontal direction by the vertical extension portion 44. Therefore, when the iron ceiling edge 30 is attached to the stiffener 40 by welding or the like, the worker is required. However, there is no need to perform welding or the like while holding down the iron ceiling ridge 30, which is preferable in that the work of mounting the iron ceiling ridge 30 can be facilitated.

The metal beam of the present invention can be applied not only to the ceiling edge 15 but also to various beams such as the floor joists 14.
