Latest Suehiro-System Co., Ltd. Patents:
The present invention relates to an anchor integrated liner and a machine installation method especially for accurate position adjustment of a base plate of a machine which is to be installed on a base such as a concrete foundation.
BACKGROUND ARTWhen a large machine is placed on a base plate to be installed on a concrete foundation, advance position adjustment of the base plate is necessary. In the conventional position adjustment of the base plate, the horizontal or vertical state is adjusted by the combination of flat liners and taper liners supporting a plurality of places of the base plate. However, the conventional installation positioning by the combination of the flat liners and the taper liners has a problem such as that a long time is required for the work of maintaining accuracy or for curing mortar fixing the liners.
Therefore, the present inventor invented an anchor integrated liner used for installation position adjustment of a base plate, with which even an unskilled worker can very easily install a machine and can make fine adjustment.
[Patent document 1] Japanese Patent No. 3775717
DISCLOSURE OF THE INVENTION Problems to Be Solved by the InventionIn the aforesaid anchor integrated liner, after a blind hole of an anchor shaft part and a screw part of a liner part are screwed to each other for the position adjustment, a gap, that is, a hollow is made on an upper surface of the screw part in the blind hole. The presence of the hollow in the concrete foundation supporting the machine poses a problem that the concrete foundation vibrates to generate noise when the machine operates. Further, after the installation position is adjusted by adjusting the screwing between the liner part and the anchor shaft part, it is necessary to weld the screw part of the anchor shaft part in order to prevent that the liner part rotates to displace the installation position.
Therefore, it is an object of the present invention to facilitate the installation of an anchor integrated liner and fix its liner part to its anchor shaft part. It is another object of the present invention to eliminate a hollow formed inside the liner part.
Means for Solving the ProblemsIn order to achieve the objects stated above, an anchor integrated liner of the present invention includes: an anchor shaft part which is provided with a shaft embeddable in a concrete foundation on which a base plate of a machine is installed and with a screw part; and a liner part which is provided on an end portion of the anchor shaft part to serve as a jig for installing the machine, which is provided with a blind hole having an inside screw screwed to the screw part and with a smooth mounting surface for the base plate, and which is capable of screw-adjusting an installation position of the machine by having the blind hole screwed to the screw part, wherein the anchor shaft part and the liner part are integrally formed, and wherein a filling hole is provided in at least one place or more of a side surface of the liner part, the filling hole being for filling a filler in a hollow which is made between the blind hole and the screw part at the time of the screw-adjustment by the blind hole and the screw part.
Another anchor integrated liner of the present invention includes: an anchor shaft part which is provided with a shaft embeddable in a concrete foundation on which a base plate of a machine is installed and with a screw part; and a liner part which is provided on an end portion of the anchor shaft part to serve as a jig for installing the machine, which is provided with a blind hole having an inside screw screwed to the screw part and with a smooth mounting surface for the base plate, and which is capable of screw-adjusting an installation position of the machine by having the blind hole screwed to the screw part, wherein the anchor shaft part and the liner part are integrally formed, wherein a filling hole is provided in at least one place or more of a side surface of the liner part, the filling hole being for filling a filler in a hollow which is made between the blind hole and the screw part at the time of the screw-adjustment by the blind hole and the screw part, and wherein a center axis of the blind hole and the screw part and a center axis of the shaft are eccentric to each other.
Still another anchor integrated liner of the present invention includes: an anchor shaft part which is provided with a shaft embeddable in a concrete foundation on which a base plate of a machine is installed and with a screw part; and a liner part which is provided on an end portion of the anchor shaft part to serve as a jig for installing the machine, which is provided with a blind hole having an inside screw screwed to the screw part and with a smooth mounting surface for the base plate, and which is capable of screw-adjusting an installation position of the machine by having the blind hole screwed to the screw part, wherein the anchor shaft part and the liner part are integrally formed, wherein a filling hole is provided in at least one place or more of a side surface of the liner part, the filling hole being for filling a filler in a hollow which is made between the blind hole and the screw part at the time of the screw-adjustment by the blind hole and the screw part, wherein a coupling member is provided between the screw part and the shaft part in the anchor shaft part, and wherein the number of the shafts attached to the coupling member is at least two or more.
In the above cases, the liner part preferably has a polygonal horizontal cross section. A plate larger than a horizontal cross-sectional area of the liner part is preferably attached to a top of the liner part.
A machine installation method of the present invention includes: forming an insertion hole in a part, of a concrete foundation, adjacent to an anchor bolt pressing a base plate of a machine; inserting a shaft of an anchor integrated liner into the insertion hole so as to make a predetermined gap between a lower surface of a screw part of the anchor integrated liner and an upper surface of the concrete foundation, the anchor integrated liner including: an anchor shaft part which is provided with the shaft embeddable in the insertion hole and with the screw part; and a liner part screwed to the screw part and having, on an upper surface, a mounting surface for the machine; horizontally and vertically adjusting the mounting surface; thereafter injecting a fixing material into the gap to form a fixed layer receiving a load in a liner axial direction; adjusting an installation position by adjusting screwing movement of the liner part; and installing the machine on an upper surface of the base plate.
EFFECT OF THE INVENTIONAccording to the present invention as structured above, at least one filling hole or more are formed for filling the filler into the hollow (gap) which is made between the blind hole of the liner part and the screw part of the anchor shaft part after the installation position of the base plate is adjusted by using the anchor integrated liner. Therefore, after the position of the base plate is adjusted by the anchor integrated liner, the filler is filled into the liner from the filling hole of the liner part, so that the hollow can be closed up. Consequently, the spread of vibration or noise generated by the operation of the machine can be prevented. Further, since the hollow in the blind hole of the liner part is closed up, the blind hole of the liner part and the screw part of the anchor shaft part can be easily fixed. This eliminates a conventionally needed work of welding and fixing the liner part after the position adjustment by the liner part, and prevents the liner part from being displaced due to the vibration when the machine operates.
The center axis of the blind hole and the screw part and the center axis of the shaft are eccentric to each other so that the shaft can keep clear of a reinforcement of the concrete foundation. Therefore, even if the reinforcement of the concrete foundation exists in the anchor insertion position, the anchor integrated liner can be disposed so as to keep clear of the reinforcement without cutting the reinforcement.
The coupling member is provided between the screw part and the shaft in the anchor shaft part and at least two shafts or more are attached to the coupling member so as to be capable of keeping clear of the reinforcement of the concrete foundation. Consequently, even if the reinforcement of the concrete foundation exists in the anchor insertion position, the anchor integrated liner can be disposed so as to keep clear of the reinforcement without cutting the reinforcement, and the center axis of the liner part can be set at the center of the plural shafts, and thus the whole anchor can be stably fixed in a well-balanced manner, which enables accurate adjustment of the base plate.
The liner part is formed to have a cross section in a polygonal shape, for example, a quadrangular shape, a hexagonal shape, an octagonal shape, or the like. This can facilitate a rotation operation of the liner part even when the installation place is narrow.
The plate wider than the cross-sectional area of the liner is attached on the top of the liner part. When the base plate is placed on the liner part, a pressure on a pressure receiving surface of the liner part is preferably smaller in order to lighten a burden to the liner part due to the load. That is, the contact area between the liner part and the base plate is preferably larger. Therefore, by making the diameter of the plate attached on the liner part larger than the diameter of the liner part, it is possible to increase the contact area of the liner part without increasing a screw diameter of the liner part.
According to the machine installation method of the present invention, the shaft is inserted so as to make the predetermined gap between the lower surface of the screw part of the anchor shaft part and the upper surface of the concrete foundation, the mounting surface of the liner part is horizontally or vertically adjusted by a hammer lightly striking it, and thereafter the fixing material which cures in a short time is injected into the gap, thereby forming the fixed layer receiving the load in the liner axial direction. Therefore, the load in the liner axial direction can be received with a surface area of the fixed layer formed around the axis of the anchor shaft part, which makes it possible to increase the strength of the whole anchor shaft part even if its shaft diameter is small. Further, the curing time of the fixing material can be shorter than the curing time of mortar put on the concrete foundation in the conventional horizontal adjustment using a flat liner, and thus it is possible to greatly shorten the time for the installation work of a machine.
