Description

[Technical field]

[0001] The present invention relates to a screw-type flat liner that is attached around the anchor bolts for mounting equipment and a frame that protrude from the top surface of the reinforced concrete of the machine foundation (on both sides of the anchor bolts for mounting equipment and a frame) to adjust the installation height of the equipment, and an installation tool for the same. [Background technology]

[0002] Fig. 12 is an explanatory diagram of a conventional method for centering equipment installation using a flat liner, a gradient liner, and a conventional anchor-integrated liner. When installing equipment (also called machinery and equipment) 1 on the upper surface of a machine foundation reinforced concrete 2 (hereinafter sometimes simply called concrete), fine adjustment in the height direction is performed using a combination of a flat liner 3 and a gradient liner 4 on the upper surface of the concrete 2 (see the left side of the figure), or using the applicant's conventional anchor-integrated liner 5 shown in Patent Documents 1 and 2 (see the right side of the figure). In the conventional equipment installation method, a flat liner 3 is placed on top of the concrete by piling up an appropriate amount of cement, which is then pressed evenly with the flat liner 3 and firmly fixed in place while ensuring horizontality with a spirit level, and the height is then adjusted with a gradient liner 4. However, for small pumps, lightweight equipment, mounting bases, etc. other than those requiring high installation precision such as large pumps, it is often the case that a flat liner is placed directly on top of the concrete and liners are stacked on top of each other.

[0003] Specifically, the installation and centering of such simple equipment / racks are performed as follows (1) to (4). (1) Attach the anchor bolts 7 for mounting the equipment and rack to the reinforced concrete machine foundation 2. (2) Attach the back nut 6 to the anchor bolt 7 for mounting the equipment / rack to determine the height of the equipment base. (3) Stack several flat liners 3. Fine-tune with gradient liners 4. Gradient liners may not be used. (4) Since it is prohibited for the back nut 6 to bear a load, loosen the back nut 6 to prevent the load from the base from acting on the back nut 6.

[0004] The problem at this time is that there is no adhesive strength between the back surface of the flat liner and the top surface of the concrete, so the contact surface between the flat liner 3 and the concrete moves during liner adjustment, making adjustment difficult (issue 1). The conventional anchor-integrated liner 5 is designed to integrate the post-installed anchor with the liner part so that the position of the liner does not move. However, if the equipment is temporarily placed during the anchor driving work, the anchor cannot be driven in, so the conventional anchor-integrated liner 5 cannot be applied (issue 2). The flat liner 3 and the gradient liner 4 require more time for vertical adjustment than the liner part of the conventional anchor-integrated liner 5 (issue 3). It is difficult to adjust the level with the flat liner 3 as it is (issue 4)

[0005] In the conventional anchor-integrated liner 5 disclosed in Patent Documents 1 and 2, the anchor is driven into concrete, so that after the equipment 1 is installed in the concrete, it is not possible to insert the liner on either side of the anchor bolt 7 for mounting the equipment / rack through the gap on the side (problem 5).

[0006] [Patent Document 1] Patent No. 3775717 [Patent Document 2] Patent No. 4065957 Summary of the Invention [Problem to be solved by the invention]

[0007] In view of the problems 1 to 5 of the prior art, the problem that the present invention aims to solve is to provide a screw-type flat liner and an installation tool therefor that facilitate centering of equipment after pouring reinforced concrete for a machine foundation. [Means for solving the problem]

[0008] As a first means for solving the above problems, the present invention provides a flat liner portion to be attached to the upper surface of a machine foundation reinforced concrete, a male thread portion protruding from one main surface of the flat liner portion; a liner portion having a female thread and a liner surface on which an equipment base is placed and which is screwed into the male thread portion; The object of the present invention is to provide a screw-type flat liner, characterized in that the installation height of the equipment of the liner portion can be adjusted while the flat liner portion is gripped and fixed. According to the first method described above, after the equipment or rack is installed on the top surface of the reinforced concrete machine foundation, a liner with a jack function can be inserted through a small gap on the side and attached so as to sandwich the anchor bolt for mounting the equipment / rack between them.

[0009] As a second means for solving the above problem, the present invention provides a threaded flat liner, which is characterized in that in the first means, the liner portion is either a cylinder with an adhesive filling hole on the outer periphery, a polygonal prism with a female thread, a polygonal nut, or a cylindrical nut. According to the second aspect, in the case of a circular nut, the work of fixing the liner portion after adjusting the installation position becomes easy. In the case of a polygonal (for example, hexagonal) nut, a commercially available product can be used, so costs can be reduced.

[0010] As a third means for solving the above-mentioned problems, the present invention provides a screw-type flat liner according to the second means, characterized in that the polygonal nut and cylindrical nut are available in a shape with an open top opening and a bag-shaped shape without a top opening, and the top opening is provided with a threaded lid that screws into place. According to the means for closing the lid by screwing it onto the nut, the adjustment margin for the installation position of the equipment by the liner portion can be increased.

[0011] As a fourth means for solving the above problems, the present invention provides an installation tool for a screw-type flat liner, which has a gripping portion on one end that is approximately the same thickness as the flat liner portion of the screw-type flat liner and grips and fixes the flat liner portion, and a handle on the other end, and which is characterized in that the liner portion of the screw-type flat liner is rotated while gripping and fixing the flat liner portion with the gripping portion to center the equipment. According to the fourth means, when adjusting the position of the equipment or plate using the liner part, the flat liner part can be gripped and fixed from the side of the equipment base with a mounting tool, so that the flat liner part does not slide sideways and can be adjusted in height. In addition, since the grip part has almost the same thickness as the flat liner part, the flat liner part can be gripped and fixed without interfering with the turning rod, hook spanner, or commercially available spanner used to rotate the liner part. Effect of the Invention

[0012] According to the present invention, after the equipment is installed on the top surface of the reinforced concrete machine foundation, the liner can be inserted through a small gap on the side and then attached, thereby shortening the adjustment work time for equipment installation and reducing construction costs. In addition, with the installation tool for the screw-type flat liner, the gripping portion has approximately the same thickness as the flat liner portion, so that the flat liner portion can be gripped and fixed without interfering with the turning rod, hook spanner, or commercially available spanner used to rotate the liner portion. In addition, when adjusting the position of the equipment or plate using the liner portion, the installation tool can be inserted through the gap on the side of the equipment base to grip and fix the flat liner portion, and height adjustment can be performed without the flat liner portion sliding sideways.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the threaded flat liner of the present invention will be described in detail below with reference to the drawings.

[0015] [Threaded Flat Liner 10] Fig. 1 is a perspective view of the threaded flat liner of the present invention, and Fig. 2 is an explanatory diagram of the installation of the threaded flat liner of the present invention. The screw-type flat liner 10 of the present invention comprises a flat liner portion 20 to be attached to the upper surface of the reinforced concrete machine foundation, a male thread portion 30 protruding from one main surface of the flat liner portion 20, and a liner portion 40 having a female thread that screws into the male thread portion 30 and has a liner surface on which an equipment base is placed on. The flat liner portion 20 is a metal flat plate having a polygonal (FIG. 1 shows a square) or elliptical shape in a plan view. The flat liner portion 20 has a male thread portion 30 provided at the center of the surface. The male thread portion 30 is a screw member having a diameter of 12 mm to 80 mm and threaded on the outer periphery. The male thread portion 30 is welded to the center of one main surface of the flat liner portion 20, or is screwed with a center hole provided therein, or is welded with a center hole provided therein.

[0016] The liner part 40 screws into the male threaded part 30 to form a mounting surface for equipment or a plate on its upper surface. The mounting surface of the liner part 40 may have any shape that can withstand the load of the equipment, and may have any of the following shapes: a cylinder with an adhesive filling hole on the outer periphery, a polygonal column with a female thread, a polygonal nut, or a cylindrical nut (Figs. 1 and 2 show a hexagonal nut). The liner part 40 of this type screws into the male threaded part 30 and moves up and down to adjust the installation height of the equipment or plate. The upper surface of the liner part 40 is also positioned at the same height as the upper surface of the machine foundation. The hexagonal liner part 40 has rotation holes on two opposing faces out of six faces. Two holes on the other opposing faces out of six faces also serve as resin filling holes 44 and are passed through holes or blind holes. The liner part 40 can be rotated by inserting a turning rod 43 into the rotation holes 42 or filling holes 44 to adjust the installation position of the equipment or plate (see FIG. 7).

[0017] [Variation 1] FIG. 3 is a side view of the threaded flat liner of the first modification. In the threaded flat liner 10A of the first modified example, the liner portion 40 is a hexagonal nut. The liner portion 40 is provided with a threaded lid 46 that covers the top surface of the nut. The other configurations are the same as those shown in Fig. 1-2. The threaded lid 46 is provided with a threaded member 46b that protrudes from one main surface of a plate 46a. The thickness of the plate 46a can be arbitrarily set according to the gap between the machine foundation reinforced concrete and the equipment. The threaded member 46b is a screw that screws into the hexagonal nut. The screw-type flat liner 10A of the first modified example having such a configuration can reduce material costs by applying commercially available hexagonal nuts to the liner portion 40. In addition, by using a screw-type lid 46 that corresponds to the gap between the concrete and the equipment, the degree of freedom in the range of application can be expanded.

[0018] [Variation 2] FIG. 4 is a side view of a threaded flat liner of the second modification. The threaded flat liner 10B of the modified example 2 has a liner portion 40 that is a hexagonal nut similar to that of the modified example 1. The length of the male thread portion 30A is longer than the male thread portion 30 shown in FIG. 1-2 and can be arbitrarily set according to the gap between the machine foundation reinforced concrete and the equipment. The threaded flat liner 10B of the second modified example having such a configuration can reduce material costs by applying a commercially available hexagonal nut to the liner portion 40. In addition, the use of the male thread portion 30A according to the gap between the concrete and the equipment can expand the flexibility of the range of application.

[0019] [Installation tool for screw-type flat liners] The fixed spanner 70, which is a mounting tool exclusively for the screw-type flat liner, has a gripping portion 72 at one end for gripping and fixing the flat liner portion 20 of the screw-type flat liner 10, and a handle 74 at the other end (see FIG. 7). The gripping portion 72 is formed to have approximately the same thickness as the flat liner portion 20 (see FIG. 7(2)). As an example, the flat liner portion 20 is set to a thickness of 6 mm to 9 mm, and the gripping portion 72 is set to a thickness of 3 mm to 6 mm, which is the same thickness as the flat liner portion or a slightly thinner thickness. Therefore, it can be inserted even in a small gap between the equipment and the reinforced concrete foundation of the machine, and the flat liner portion 20 can be gripped and fixed. In addition, since the liner portion 40 on the upper surface is a cylindrical type and a hexagonal nut type, it is rotated with a hook spanner, a turning rod 43, etc. to adjust the installation position and perform centering work, but the flat liner portion 20 can be fixed with the mounting tool without interfering with these tools. The flat liner portion 20 can be grasped and fixed with a commercially available wrench, etc., but since commercially available wrenches, etc. are about 30 mm thick, it may not be possible to grasp and fix it in the gap between the equipment and the reinforced concrete of the machine foundation. Even if it is possible to grasp and fix it, there is a risk that the liner portion 40 cannot be rotated with a turning rod, etc. With such an installation tool, even if there is a small gap, the flat liner portion 20 can be gripped and fixed with the gripping portion 72, and the liner portion 40 of the threaded flat liner can be rotated with a hook wrench, a twisting rod, or a commercially available wrench to center the equipment.

[0020] [How to install the equipment] Fig. 5 is an explanatory diagram 1 of the equipment installation method. Fig. 6 is an explanatory diagram 2 of the equipment installation method. Fig. 7 is an explanatory diagram 3 of the equipment installation method. Fig. 8 is an explanatory diagram 4 of the equipment installation method. The equipment is placed on the top surface of the reinforced concrete machine foundation 2. At this time, back nuts 6 are installed on the anchor bolts 7 for equipment / installation installation installed on the top surface of the reinforced concrete machine foundation 2, and then the equipment is temporarily placed. The anchor bolts 7 for equipment / frame installation are either set together with the reinforced concrete machine foundation 2 in advance, or are set in place after concrete has been filled into the box-cut holes. At this time, the equipment is kept level by the back nuts attached to the anchor bolts. (If the anchor bolts can be installed in concrete)

[0021] A screw-type flat liner 10 is inserted into the gap between the equipment and the reinforced concrete of the machine foundation and aligned with the marked position. Mortar, non-shrink mortar, or adhesive is injected between the bottom surface of the flat liner portion 20 and the top surface of the reinforced concrete machine foundation 2 to fix it horizontally. At this time, a level 60 is placed against the liner portion 40 to align it horizontally (see FIG. 8). With the flat liner portion 20 clamped and fixed with the fixed spanner 70, a turning rod 43, a hook spanner, a spanner, etc. is inserted into the rotation hole 42 or the filling hole 44 of the liner portion 40 and rotated to raise the liner portion 40. After loosening the back nut 6, the equipment installation position is adjusted, centered, and leveled (see Figure 7). After the centering of the device is completed, epoxy resin is injected into the filling hole 44 of the liner portion 40 and it is confirmed that the resin comes out of the opposing filling hole 44. The locking spanner 70 is removed and the job is completed.

[0022] According to the screw-type flat liner 10 of the present invention, after the equipment is installed on the top surface of the reinforced concrete foundation, the liner can be inserted through a small gap on the side to install it, which shortens the time required for adjusting the equipment installation and reduces the construction cost. In addition, when adjusting the position of the equipment or plate using the liner part 40, the flat liner part 20 can be installed without sliding sideways using an installation tool dedicated to the screw-type flat liner.

[0023] [Variation 3] Fig. 9 is a perspective view of a threaded flat liner of the modified example 3. Fig. 10 is a plan view of the threaded flat liner of the modified example 3. Fig. 11 is a side view of the threaded flat liner of the modified example 3. The screw-type flat liner 10C of the third modification includes a flat liner part 20 to be attached to the upper surface of the reinforced concrete machine foundation 2, a male thread part 30 protruding from one main surface of the flat liner part 20, and a liner part 40A having a female thread that screws into the male thread part 30 and has a liner surface on which an equipment base is placed on. The liner part 40A also has a blind hole formed inside and has an inner peripheral surface that is threaded. With the screw-type flat liner 10C configured as described above, after the equipment or rack is installed on the top surface of the reinforced concrete machine foundation, the liner with jacking function can be inserted through a small gap on the side and the anchor bolt for mounting the equipment / rack can be sandwiched between them.

[0024] The screw-type flat liners 10, 10A, 10B, and 10C of the present invention can be used as permanent liners to be attached around anchor bolts for mounting equipment and racks that protrude from the top surface of the reinforced concrete for a machine foundation, and can also be used as temporary liners on the top surface of the reinforced concrete for a machine foundation other than the area where a box-punch hole is provided.

[0025] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications can be made without departing from the spirit and scope of the present invention. Furthermore, the present invention is not limited to the combinations shown in the embodiments, but can be implemented in various combinations. [Explanation of symbols]
