[0006]

However, in such a conventional equipment installation foundation 1 ', since the anchor bolt 7 projects from the upper surface of the foundation concrete 38 by about 100 to 150 mm, the equipment is to be brought into the place. For the basics of, do you do major curing of the screw part,
It was necessary to take measures such as adding a detour or performing basic work after loading the equipment. As a result, temporary construction costs increased and the process was hindered, and it was required to review the entire process including adjustment of the earth-building process.

Further, such a conventional equipment installation foundation and its construction method require an early construction because it requires a long period of time for the earthwork construction. However, it is necessary to install the equipment like an equipment such as an exhaust heat recovery boiler. It is often difficult to install the equipment installation foundation after the large-scale transporter loaded with the exhaust heat recovery boiler has passed over the installation foundation of the high-pressure water supply pump. Since the foundation bolts of the water supply pump will obstruct the passage of the large-sized carrier, the large-scale carrier will be forced to undertake the foundation work after it has passed, which may be a major obstacle to the overall equipment installation process. there were. As described above, in the equipment installation foundation and the equipment installation construction method according to the prior art, no consideration was given to the process and the like when installing equipment such as an exhaust heat recovery boiler.

The object of the present invention is to solve the problems of the prior art. Even after the installation foundation of the equipment has been constructed, the equipment can be carried in easily and can be installed quickly, and the construction work and the installation work will not interfere with each other. It is an object of the present invention to provide an equipment installation foundation and an equipment installation construction method that can avoid the above problems and can shorten the equipment installation process.

[0009]

According to the present invention, it is possible to install equipment by placing foundation concrete in a state where the foundation bolt itself is not set until the intermediate stage of construction and incorporating the foundation bolt into the foundation frame at the time of equipment installation. Is the equipment installation foundation. That is, a foundation bolt for fixing the equipment to the foundation concrete, a guide tube through which the foundation bolt is inserted, and a lock for fixing one end side of the foundation bolt that is fixed to one end of the guide bolt and is opposite to the installation side of the equipment. In the equipment installation foundation including a stop member, the other end of the guide cylinder is located at the upper surface of the foundation concrete or inside from the upper surface, and one end side of the foundation bolt and the locking member can be engaged and disengaged. The purpose is achieved.

Further, in the above invention, a vertically elongated member is fixed to one end side of the foundation bolt, and a vertically elongated hole is formed in the locking member. The vertically elongated hole and the vertically elongated member are arranged in the vertically elongated directions. It can be inserted.

Further, the above object is to provide an equipment installation foundation provided with foundation bolts for fixing the equipment to foundation concrete,
The other end of the foundation bolt on the equipment installation side is also achieved by being located at the top of the foundation concrete or inside from this top.

Further, a locking member for locking one end side of the foundation bolt opposite to the installation side of the equipment is fixed to one end of a guide tube through which a foundation bolt for fixing the equipment to the foundation concrete is inserted,
A device that inserts a foundation bolt into a guide cylinder, locks one end side of this foundation bolt to a locking member, fixes the other end side of this foundation bolt to the equipment, and then places foundation concrete inside and outside the guide cylinder. In the installation method, a vertically long member is fixed to one end side of the foundation bolt, and vertically long holes are formed in the locking member so that the vertically elongated members can be inserted into each other in the vertically long direction. This is accomplished by rotating the base bolt and the vertical member by a predetermined angle after inserting the vertical member, locking the vertical member of the base bolt to the locking member, and fixing the device to the base concrete.

[0013]

[Operation] Since the other end of the guide cylinder is located on the upper surface of the basic concrete or inside from the upper surface, the basic concrete of the equipment that has been constructed in advance when carrying in equipment such as the exhaust heat recovery boiler You can easily move up. Since the one end side of the base bolt and the locking member at one end of the guide tube are detachable, lock and set the base bolt after carrying in the equipment such as the exhaust heat recovery boiler. As a result, the loading of equipment such as the exhaust heat recovery boiler is not obstructed by the foundation bolt, and the foundation bolt is not damaged by the loading of the equipment. Further, since the equipment can be installed immediately after the equipment such as the exhaust heat recovery boiler is brought in, the interference between the earthwork construction and the installation work can be avoided, and the equipment process such as the exhaust heat recovery boiler and the high-pressure water supply pump can be processed. It can be shortened.

Further, in the above invention, a vertically elongated member is fixed to one end side of the foundation bolt, and a vertically elongated hole is formed in the locking member, and the vertically elongated hole and the vertically elongated member are arranged in the vertically elongated directions. Since it can be inserted, in addition to the effects of the above-described invention, the positioning and setting of the base bolt when the device is installed is easy, and the base bolt and the member that locks the base bolt are easy and economical to manufacture.

Further, the above object is to provide an equipment installation foundation having foundation bolts for fixing the equipment to foundation concrete,
Since the other end of the foundation bolt on the installation side of the equipment is located on the top surface of the foundation concrete or inside from this top surface, the foundation bolt does not become an obstacle when carrying in equipment such as an exhaust heat recovery boiler. Can be easily moved on basic concrete. In addition, the foundation bolt is not damaged by the loading of the above equipment. Furthermore, after the equipment such as the exhaust heat recovery boiler is brought in, the equipment can be installed immediately, and the interference between the earthwork and the installation work can be avoided, and the process steps of the equipment such as the exhaust heat recovery boiler and the high-pressure feed pump can be shortened. Can be planned.

Further, a vertically long member is fixed to one end side of the foundation bolt, and vertically long holes are formed in the locking member so that the vertically long members can be inserted into each other in the vertically long direction, and the vertically long member is inserted in the vertically long hole. After inserting, the base bolt and the vertical member are rotated by a predetermined angle and the vertical member is locked to the locking member, so that it is easy to carry in other equipment, etc., and the positioning setting of the basic bolt is easy. You can surely install the equipment.
