Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a mounting device for attaching and fixing a small beam to a base beam constituting a floor beam of a house, for example.

(Prior art) In ordinary houses built by so-called prefabricated construction, the floor beams on the first or second floor are steel frame beams with a roughly E-shaped or U-shaped cross section, such as so-called H-shaped steel or C-shaped steel. It is usually composed of a combination of bodies. In other words, the surrounding beams and the beams that are appropriately installed on the surrounding beams according to their strength constitute the base beams, and of course, those having a large section modulus are adopted as these beams. Further, a plurality of small beams are installed on the base beam at predetermined intervals in a direction substantially perpendicular to the base beam. Since these beams reinforce the base beam, their section modulus is smaller than that of the base beam. Other members such as a floor plate and a ceiling plate are attached to these base beams and small beams.

(Problem that the invention attempts to solve) By the way, the floor beam constructed in this way is
For example, there are cases in which floor beams are manufactured in a factory and then transported as is to a construction site and installed in a predetermined position, and cases in which floor beams are assembled at a factory and then disassembled, and then transported in this state to a construction site and reassembled. However, in order to simplify the transportation work, the method of transporting the floor beams in a disassembled state is often used.

Therefore, it is not possible to attach and fix the small beam to the base beam by means such as welding, and because the base beam has a roughly E-shaped or U-shaped cross section without a stiffener (attachment part). , must be connected and fixed to each other via some kind of attachment device. That is,
After the base beam is assembled into a predetermined shape, a mounting device is attached to it, and the side walls of the small beam are further attached to this mounting device.

In this case, unless a large number of small beams are attached with their center center pitches aligned, the attachment devices for the members attached to these beams will be different. To do this, it is reliable to orient each small beam in the same direction and attach and fix it to the same side wall surface. However, if the beam has a U-shaped cross section, it is easy to align the directions, but if the beam has an E-shaped cross section, different sides of the web may be attached and fixed, making it difficult to install accurately. There was a problem that the usability decreased.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to easily adjust the center center pitch between the small beams for a base beam without a stiffener.
It is an object of the present invention to provide a beam attachment device that enables accurate attachment and improves workability.

[Structure of the idea]

(Means and effects for solving the problem) That is, the present invention is a method for attaching a plurality of small beams at predetermined intervals in a direction orthogonal to a base beam having an E-shaped cross section or a U-shaped cross section. It has upper and lower bent pieces that are fixed to the upper and lower flanges of the base beam, and a connecting piece that connects these bent pieces is bent into a U-shaped cross section that is attached at a predetermined distance from the web of the base beam. a device main body, a projecting piece provided on the rear side of the connecting piece of the device main body in a direction perpendicular to the base beam, and to which the side wall of the small beam is attached to one side; A beam mounting device characterized by comprising a mounting regulating piece provided in the side direction opposite to the small beam mounting side and holding the center center pitch between the small beams by regulating the mounting of the small beams. be.

When attaching the small beam to the protruding piece, since an attachment regulating piece protrudes from one side of the protruding piece, it cannot be attached to this side. Inevitably, attach a small beam to the side of the protrusion that does not have a mounting restriction piece. Therefore, there is no mistake in the installation work of the beams, and the center pitch between the beams can be reliably maintained when they are attached to the projecting piece.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. FIG. 1 shows, for example, a floor beam of a prefabricated house in plan view. Reference numeral 1 denotes base beams constituting a frame that is assembled into a rectangular frame shape and is erected at predetermined intervals, and here all steel frames having a substantially E-shaped cross section are used. Small beams 3 are installed between the base beams 1 via mounting devices 2, which will be described later. Each of the small beams 3 is made of a steel frame material having a substantially E-shaped cross section, and has a section modulus smaller than that of the base beam 1.

The mounting device 2 is designed as shown in FIGS. 2 to 4. That is, 4 is a device main body made of a plate bent into a U-shaped cross section. Attachment holes 5 are formed in both the upper and lower bent pieces 4a, 4a of the device main body 4. Further, the dimension between the upper and lower end surfaces of both bent pieces 4a, 4a of the device main body 4 substantially matches the dimension between the upper and lower flanges 1a, 1a inner end surfaces of the base beam 1. Therefore, the device main body 4 can be removably fitted to the upper and lower flanges 1a, 1a of the base beam 1. Note that 6 shown only in FIG. 4 is provided over the inner surface of the upper and lower bent pieces 4a, 4a of the apparatus main body 4 and the connecting piece 4b that connects these bent pieces 4a, 4a. This is a reinforcing plate for A projecting piece 8 is provided on the back side of the connecting piece 4b of the device main body 4 in a direction perpendicular to the connecting piece 4b.
To explain, the projecting piece 8 is fixed to the side surface opposite to the side surface on which the reinforcing plate 6 is provided, for example, by means such as welding. The vertical dimension of the projecting piece 8 may be approximately the same as, or smaller than, the dimension between the upper and lower flanges 3a of the small beam 3. Further, the length of the protrusion may be such that the mounting holes 9, 9 for mounting and fixing the small beam 3 can be formed therein. Furthermore, an attachment regulating piece 10 is integrally formed on the tip edge of the protruding piece 8 in a direction substantially perpendicular thereto.
Both the vertical dimensions and the protrusion length of the attachment regulating piece 10 are not limited. However, it is necessary to accurately locate the mounting position of the protruding piece 8 on the device main body 4, and the bending direction of the mounting regulating piece 10 must be aligned in the same direction.

Therefore, when actually assembling a floor beam made of such members, it is carried out as described below. That is, first, the base beam 1 is assembled into a predetermined shape, and then the attachment device 2 is attached thereto. As shown in FIG. 2, mounting holes 11 are formed at predetermined intervals at the ends of the upper and lower flanges 1a, 1a of the base beam 1.
The mounting holes 5 and 5 are connected and then tightened and fixed using a fixture consisting of a bolt and nut (not shown). Naturally, the attachment device 2 will be attached in the direction in which the projecting piece 8 protrudes from the base beam 1. Furthermore, at this time, it is necessary to align each mounting device 2 in the same direction. To do this, care should be taken so that all the attachment regulating pieces 10 provided at the tips of the protruding pieces 8 protrude in the same direction. If any of the mounting devices 2 is installed upside down, the installation regulation piece 10
You can easily tell because the protruding direction of the left and right is reversed. After all the attachment devices 2 are attached and fixed to the base beam 1, the small beam 3 is attached to this projecting piece 8. The protruding piece 8 has two sides, and since the above-mentioned attachment regulating piece 10 protrudes from one side, the attachment of the small beam 3 is restricted and cannot be attached. Therefore, the web 3b of the small beam 3 must be attached to the side surface of the protruding piece 8 where the attachment regulating piece 10 is not provided. All the beams 3 are attached to the mounting device 2 at the same position, and as a result, the center pitches P of the beams 3 are aligned in the same manner.

In this state, the connecting piece 4b of the device main body 4 is parallel to the web 1b of the base beam 1 with a predetermined distance therebetween, and a space 1 is created between the base beam 1 and the device main body 4.
1A is formed. Therefore, this space 11A
For example, water pipes, gas pipes, etc. can be laid along the base beam 1 by using the base beam 1.

In the above embodiment, the attachment regulating piece 10 is integrally formed by bending along the tip edge of the protruding piece 8, but the invention is not limited to this;
Any material may be used as long as it protrudes from one side of the beam and restricts attachment of the side wall of the small beam 3.

Further, although the base beam 1 has an E-shaped cross section, it may have a U-shaped cross section.

[Effect of idea]

As explained above, the present invention has a relatively simple structure consisting of a device main body with a U-shaped cross section and a protruding piece with an attachment regulating piece, but it is easy to use when attaching a small beam. The center core pitch can be taken out very easily and accurately, improving work efficiency and providing an extremely effective space.
