BACKGROUND OF THE INVENTION
The present invention relates to an installation base for installing equipment above a floor material having a through hole such as a grating floor, and more particularly to an installation base for installing an anti-vibration equipment such as a measuring instrument.
[0002]
[Prior art]
When installing a measuring device above a grating floor with a large number of through-holes at a construction site, etc., first install the installation stand to prevent the measuring device base (such as a tripod) from falling out of the through-hole. Lay on the grating floor and install the measuring equipment on this installation base. However, the grating floor is easily vibrated due to the influence of the vibrations caused by the surrounding work and the passersby, so that there is a problem that the position of the measuring device on the installation base is shifted.
[0003]
Therefore, the conventional installation base is installed on the exposed portion of the beam member that supports the grating floor so that the measuring device is not affected by the vibration of the grating floor.
[0004]
[Problems to be solved by the invention]
However, the conventional installation table has a drawback that the installation table cannot be attached when there is no exposed portion of the beam member. For this reason, when installing gratings on most of the floor surface, especially in the case of a plant building of a thermal power plant, a conventional installation table could not be attached.
[0005]
The present invention has been made in view of such circumstances, and an object thereof is to provide an installation base that is not affected by the vibration of the grating floor and can be fixed to portions other than the exposed portion of the beam member.
[0006]
[Means for solving the problems]
To accomplish the pre-Symbol purpose, the flooring having a number of through holes a mount base for placing the device on the floor surface formed by laying on the beam member, the mount base is A plurality of protrusions that penetrate the through-holes of the flooring material and come into contact with the beam member on the lower surface thereof, and pass the protrusions through the through-hole to make contact with the beam member. The installation table is supported by the beam member via the protrusion so that the installation table does not come into contact with the floor material.
[0007]
According to the first aspect of the invention, since the installation table is supported by the beam member so as not to contact the floor material, even if the floor material vibrates, the vibration is not directly transmitted to the installation table, and the installation table hardly vibrates. do not do. Therefore, the installation stand of the present invention is suitable for installing vibration isolation equipment such as measurement equipment. Moreover, the installation stand of the present invention allows the installation stand to be attached even if the beam member is not exposed because the protruding portion is inserted through the through hole of the floor material and brought into contact with the beam member.
[0008]
According to the second aspect of the present invention, since the protruding portion is detachable, the protruding portion can be selected and attached at a position where it does not contact the flooring, and can easily correspond to the arrangement of the through holes in the flooring. can do.
According to the invention of claim 3, since the installation table is fixed to the beam member by the fixing means so as to be in non-contact with the floor material, the installation table can be fixed with almost no vibration, The equipment installed on the installation table can be stabilized.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of an installation stand according to the present invention will be described in detail with reference to the accompanying drawings.
The installation base 10 according to the embodiment of the present invention is a base for installing the measuring device 22 above the grating floor 24 as shown in FIGS. 1 and 2. The grating floor 24 is formed in a lattice shape to form a large number of through holes, and is supported on the upper surface of the beam member 26.
[0010]
The installation base 10 is mainly composed of a measuring instrument base 12, a support column 14, and a pedestal 16. The pedestal 16 is formed in a rectangular shape, and a columnar column 14 is vertically installed on the upper surface of the pedestal 16. A circular measuring instrument table 12 is installed on the upper side of the support column 14, and a measuring instrument 22 is installed on the measuring instrument table 12.
As shown in FIG. 3, a large number of pins (corresponding to protrusions) 18, 18... Are disposed on the lower surface of the pedestal 16. The pin 18 is formed to have a thickness that can be inserted into the through hole of the grating floor 24, and the length L of the pin 18 is longer than the thickness t of the grating floor 24. The number and arrangement of the pins 18 may be any as long as the pins 18 penetrate through the through holes without contacting the grating floor 24. For example, as shown in FIG. 4, a large number of screw holes 19, 19... Are formed on the lower surface of the base 16, and positions where the screw holes 19 do not contact the grating floor 24 (positions indicated by bold lines in FIG. 4). Select and install pin 18. Thereby, even if it is the joint part of the grating floor 24, the pin 18 can be inserted in the through-hole of the grating floor 24, and the base 16 can be mounted in the beam member 26 as shown in FIG.
[0011]
The pedestal 16 placed on the beam member 26 is fixed by a fixing member (corresponding to a fixing means) 20. The fixing member 20 is composed of a support member 30 that is formed in a substantially U-shape using a plurality of giant clam vise, and a threaded shaft 32 provided with a handle 34 at an end. The threaded shaft 32 is screwed into the end of the support member 30, and by screwing the threaded shaft 32, the threaded shaft 32 can be sandwiched between the tip 32 </ b> A of the threaded shaft 32 and the other end 30 </ b> A of the support member 30. Become. Further, the support member 30 formed in a substantially U shape is formed with a thickness that can be inserted into the through hole of the grating floor 24.
[0012]
Next, the operation of the installation base 10 configured as described above will be described.
First, the pedestal 16 is placed on the beam member 26 from above the grating floor 24, and the pin 18 is inserted into the through hole of the grating floor 24 and brought into contact with the beam member 26. At this time, since the length L of the pin 18 is longer than the thickness t of the grating floor 24, a gap is formed between the pedestal 16 and the grating floor 24, and the pedestal 16 is not in contact with the grating floor 24. Supported by the member 26.
[0013]
Next, the support member 30 of the fixing member 20 is inserted through the through hole of the grating floor 24, and the handle 34 is rotated to screw the threaded shaft 32 into the support member 30, thereby supporting the end portion 32 </ b> A of the threaded shaft 32. At the end portion 30 </ b> A of the member 30, the upper surface of the pedestal 16 and the lower surface of the beam member 26 are clamped from both outsides, and the pedestal 16 is fixed to the beam member 26. At this time, the fixing member 20 is prevented from contacting the grating floor 24. Thereby, the installation base 10 can be fixed to the beam member 26 without contacting the grating floor 24.
[0014]
As described above, in the installation base 10 of the present embodiment, the pin 18 longer than the thickness of the grating floor 24 is attached to the lower surface of the pedestal 16, and the pin 18 is inserted into the through hole of the grating floor 24 and contacts the beam member 26. Therefore, the installation base 10 can be installed on the beam member 26 without contacting the grating floor 24. Since the beam member 26 has high rigidity and is unlikely to vibrate unlike the grating floor 24, the installation base 10 fixed to the beam member 26 hardly vibrates. Therefore, the installation base 10 of the present embodiment is suitable for installing a vibration isolating device such as the measuring device 22 that is susceptible to vibration.
[0015]
In the above-described embodiment, the plurality of pins 18 are formed to have the same length, but the present invention is not limited to this. For example, as shown in FIG. 5, when the beam member 26 and the grating floor 24 are installed at an inclination, the pedestal 16 can be attached horizontally by attaching the pins 18 </ b> A and 18 </ b> B having different lengths. . As described above, when the pins 18A and 18B having different lengths are attached to the pedestal 16, the pedestal 16 can be moved at an arbitrary angle even when the beam member 26 is installed in a gradient or the shape is deformed. Can be installed.
[0016]
Further, the structure of the fixing member 20 is not limited to the above-described embodiment, and any structure may be used as long as the fixing base 20 can be fixed to the beam member 26 without bringing the installation base 10 into contact with the grating floor 24. For example, the fixing member 40 shown in FIGS. 6 and 7 is an integrated unit of four giant clams, and includes four leg members 46, 46... And one threaded shaft 44. . A handle 42 is provided at one end of the threaded shaft 44, and a pressing portion 48 is formed at the other end. Further, a wedge member 50 provided with a pair of wedge portions 50A, 50A is screwed onto the threaded shaft 44. Further, a substantially rectangular support member 52 is attached to the threaded shaft 44 so as to be slidable in the axial direction of the threaded shaft 44, and substantially U-shaped leg members 46, 46. It is rotatably attached via 51, 51. At the end of the leg member 46, an abutting portion 46A with which the wedge portion 50A abuts is formed. Further, a nut 54 shown in FIG. 7 is screwed onto the threaded shaft 44, and the vertical position of the support member 52 is regulated by the nut 54.
[0017]
The fixing member 40 configured as described above opens the leg members 46 and 46 as shown by a two-dot chain line in FIG. 7 and inserts them through the through holes of the grating floor 24, and the pressing portion 48 of the threaded shaft 44 is mounted on the base. After being brought into contact with 16, the threaded shaft 44 is rotated via the handle 42. When the threaded shaft 44 is rotated, the wedge member 50 screwed to the threaded shaft 44 slides downward, and the wedge portion 50A abuts against the abutting portion 46A of the leg member 46 and presses outward. As a result, the leg members 46 and 46 rotate in the closing direction, and the pressing portion 48 of the threaded shaft 44 and the leg member 46 sandwich the upper surface of the pedestal 16 and the lower surface of the beam member 26, thereby It can be fixed to the member 26. Thus, the fixing member 40 can fix the pedestal 16 to the beam member 26 at four locations by a single operation.
