Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting base for various machines.

[0002]

2. Description of the Related Art Conventionally, when forming the foundation of a mechanical mount as shown in FIG. 4, since the pillars 17 and the beams 18 are made of reinforced concrete, at the time of making these, the attachment of the supporting work and the arrangement of the reinforcing bars are arranged. After mounting the formwork, the penetration sleeve and the embedded metal fitting, concrete was placed and the formwork was removed after a predetermined curing period.

[0003]

As shown in FIG. 4, when all of the installation bases for various machines are made of reinforced concrete, the support work is attached, the reinforcement is arranged, the form is attached, the penetrating sleeve and the embedding are embedded. It is necessary to place concrete after mounting the hardware,
Until the supporting work and the formwork were removed, there was a problem that the construction work could not be performed under the beam, and the construction period could be prolonged on site.

The present invention has been proposed in view of the above problems, and an object thereof is to provide a base stand for installation of various machines which can shorten the construction period on site.

[0005]

In order to achieve the above-mentioned object, an installation base stand for various machines of the present invention is composed of reinforced concrete columns and steel plate concrete beams,
The joint between the two is more connected to the beam fixing anchor, the scissors, and the connecting bar.

[0006]

[Function] The installation base pedestal of various machines of the present invention is configured as described above, and the ramen structure serving as the installation base pedestal of various machines is made up of reinforced concrete columns and steel plate concrete beams. The construction period is shortened. In other words, the production of the steel formwork that will become the beam and the installation of the penetration sleeve, stud, beam upper end streak, etc. are performed at the factory,
The steel formwork was attached to the reinforced concrete columns, and after the installation, concrete was placed on the steel formwork,
Since it is a steel plate concrete beam, compared to reinforced concrete beams, there is no need for formwork and support work, and it is possible to install various machines under the beam in advance, which shortens the construction period on site.

[0007]

EXAMPLES Next, an explanation will be given of an installation base stand for various machines according to the present invention with reference to an example shown in FIGS. 1 to 3, in which 1 is a reinforced concrete column, and the reinforced concrete column 1 is manufactured locally by a reinforced concrete construction method. To do. At this time, a taper portion 4 is provided in a portion of the reinforced concrete pillar 1 that is to be joined to the steel plate concrete beam 2, and a joining anchor bolt 11 is embedded at a predetermined position in the taper portion 4 (Fig. 3).

When the concrete strength of the reinforced concrete pillar 1 is obtained, a steel formwork (steel formwork to be the steel plate concrete beam 2) produced in advance in the factory is attached to the anchor bolts 11 for joining, Reinforced concrete pillar 1
And the steel plate concrete beam 2 are joined. At this time, as shown in FIG. 3, the strut muscle 12 and the connecting muscle 8 are attached.

A through sleeve 6 (see FIG. 2), a beam upper end streak 5, a stud 10, an embedded metal object, etc. are attached to a steel form frame which becomes the steel plate concrete beam 2 at a manufacturing stage in a factory. Steel plate concrete beam 2 and reinforcement 12,
After attaching the connecting bar 8, attach the formwork to the corner 3 of the reinforced concrete pillar 1 and the steel plate concrete beam 2,
Concrete is placed on this form and the steel beam concrete beam 2.

In FIG. 2, 7 is an upper opening of the steel beam concrete beam 2, 13 is a steel plate of the beam 2, 14 is a column haunch reinforcement bar, 15 is a column vertical bar, 16 is a column hoop bar, and FIG. 1 in 2
Reference numeral 9 is an inverted U-shaped member of the same beam 2, 20 is an upwardly facing U-shaped member of the same beam 2, 21 is a U-shaped member of the same beam 2, 22 is a vertical stiffener of the same beam 2, and 23 is a lateral stiffener of the same beam 2. , 24 are vertical ribs, 25
Is an upper flange, and 26 is a support rod.

Since no support work is required at the time of installing the foundation pedestal for the installation of these various machines, the reinforced concrete pillar 1
As soon as the concrete pouring is completed, it is possible to install machinery under the beam. Since the penetrating sleeve 6, embedded metal fittings, etc. are attached to the steel plate concrete beam 2 in advance at the factory, the number of construction steps on site is reduced.

Steel plate Inside the steel plate of the concrete beam 2,
As shown in FIG. 3, since the stud 10, the beam upper end streak 5 and the like are attached at the factory, and the side plate is attached, the number of construction steps at the site is also reduced in this respect. In addition, a taper 4 portion is provided at a joint portion of the reinforced concrete pillar 1 to the steel plate concrete beam 2, and a joining anchor bolt 11 is embedded in the taper 4 portion, and a mounting hole is provided at a bottom portion of the steel plate concrete beam 2. It has been drilled, and during construction,
The steel-plate-concrete beam 2 and the reinforced-concrete pillar 1 are joined simply by placing the steel-plate-concrete beam 2 on the reinforced-concrete pillar 1 and joining them with a nut.

Further, the connecting muscles 12 and the connecting muscles 8 are used in this joint portion, and the joint portion is strengthened.

[0014]

As described above, the installation base of various machines according to the present invention uses the reinforced concrete columns and steel plate concrete beams as the ramen structure to be the installation base of various machines. Can be shortened. That is, the steel formwork that will become the beam is manufactured, and the penetration sleeve, stud, beam upper end bar, etc. are installed at the factory, and at the site, the steel formwork is installed on the reinforced concrete column, and after installation,
Since concrete is cast into the steel formwork to make it a steel plate concrete beam, it is possible to eliminate the need for formwork and supporting work as compared to reinforced concrete beams, enabling the pre-installation of various machines under the beam, The construction period on site can be shortened.
