Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a precise positioning method using swing type anchor bolts of anchor bolts embedded in foundation concrete.
[0002]
[Prior art]
It is necessary to attach anchor bolts to various foundations that firmly connect the foundation and the upper structural frame installed on the foundation. Needless to say, the anchor bolt has its lower part embedded in the foundation and its upper part protruding from the upper surface of the foundation.
[0003]
In a conventional wooden frame construction method, all the anchor bolt through holes that open to the base are individually measured for the position of the anchor bolts standing on the top of the foundation at the building site, and the positions are attached. It was drilled after writing on the previous foundation. The mounting of the foundation on the top of the foundation was able to be performed only after such a troublesome work and was a very inefficient work.
[0004]
Even with the wooden frame construction method, unlike the above, through holes for anchor bolts should be drilled in advance when the foundation is precut, and at the construction site, the carried foundation is immediately attached to the top of the foundation. For example, the efficiency is very good. However, in order to realize this, it is assumed that the anchor bolt protruding from the base top end is accurately positioned and its height is also adjusted accurately.
[0005]
In prefabricated construction and steel construction, their superstructure is factory-produced, and the degree of freedom at the construction site is extremely low, so anchor bolts for coupling with these are also accurately attached to the foundation. It is required to be.
[0006]
To fix such anchor bolts to the foundation, before hardening the cast concrete, a water line is applied horizontally along the reference core line on the top edge of the rising part of the foundation, and this water is applied. A technique is often used in which anchor bolts are driven in order along the yarn in accordance with the drawings while measuring the dimensions, and these anchor bolts are fixed to the formwork by the support means in the driven state. However, since this needs to be completed within a relatively short time before the concrete is hardened, it is rushed, the measurement tends to be inaccurate, and the anchor bolts often fall out. Is the actual situation. In addition, this technique has a problem that the measurement method tends to be displaced even by a small external force, and it is difficult to ensure the reliability of the reference method. Furthermore, there is a problem that this method is an obstacle to various operations.
[0007]
The technique of patent document 1 is proposed as a thing regarding improvement of such a technique. In place of the method, this is standing on the outside of the corner portion of the base formwork, and a support leg that can be adjusted in height, and a water thread that is slidable in the horizontal direction on the L-shaped side plate at the upper end. There is no difference from the conventional technique except that it is made of a hooking portion for use and can be easily replaced by a water string. Therefore, none of the problems described above have been solved.
[0008]
Among the techniques proposed for the purpose of accurately attaching the anchor bolt to the foundation, there are the following.
[0009]
One is to secure an accurate positioning by fixing the anchor bolt to the formwork through the support means, and there are proposals in Patent Document 2 and Patent Document 3. However, the contents of the proposals in Patent Documents 2 and 3 are all based on the accuracy of the formwork for foundation construction, and the anchor bolt mounting accuracy to the anchor bolt support or anchor bolt holder that is directly or indirectly attached thereto In practice, it is considered that the required anchor bolt positioning accuracy required cannot be obtained.
[0010]
As long as the formwork for foundation construction is used at the present time, it is unavoidable that a slight displacement occurs due to the strong pressure applied when placing concrete. For this reason, no matter how much the positioning accuracy in supporting the anchor bolt support or the like is increased, a displacement is caused on the mold frame side, and accordingly, the same displacement is caused in itself. Furthermore, the strong pressure applied when placing concrete also applies to the anchor bolts supported by the support, etc., and unless these supports are very strong, they cannot withstand this pressure. It is inevitable that some displacement occurs.
[0011]
Therefore, with the technique of fixing the anchor bolt to the formwork through the supporting means as shown in Patent Documents 2 and 3, the positioning accuracy cannot be sufficiently increased.
[0012]
For other things, fix the lower part to the lower structure such as anchor plate with anchor bolt holder or fixing leg, etc., and fix the upper part to the upper structure such as positioning plate or positioning jig, etc. There is a technique of disposing and fixing the lower structure to concrete or the like and positioning the anchor bolt at a predetermined position, and there are proposals in Patent Document 4 and Patent Document 5.
[0013]
In Patent Documents 4 and 5, for example, the former is to provide a positioning plate in which an upper end thread portion of an anchor bolt can be easily inserted and removed, and the latter is lowered from four sides of an upper structure jig body. However, as described above, each of the above-mentioned strong anchor frames constitutes an accurate positioning of anchor bolts. It is based on the technology to be realized.
[0014]
As described above, the anchor frames shown in Patent Documents 4 and 5 are extremely strong, so that they can withstand the pressure of the concrete to be placed and placed relatively easily if they are correctly installed. It is recognized that the accuracy can be maintained. Needless to say, however, in such a configuration, as the length of the anchor bolt increases, it is necessary to increase the strength of the frame. Therefore, the cross section of the frame further increases and the weight also increases. Along with this, the workability deteriorates and the cost is unavoidable.
[0015]
In addition to this, there is also a technique to support the anchor bolt on the reinforcing bar for foundation reinforcement, but this is easily and greatly displaced when placing concrete, which is almost useful for accurate positioning of the anchor bolt. You should say no.

DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a core mark for an anchor bolt or a reference core shaft of an anchor bolt unit is displayed on immovable discarded concrete, and the anchor bolt itself or the anchor bolt unit is attached to the core mark on the discarded concrete. An anchor bolt or anchor bolt unit that is tilted by placing the anchor bolt or anchor bolt unit in a tiltable manner after placing the reference core shaft in an up-and-down correspondence, then placing concrete, and setting the concrete before hardening Is adjusted so that the anchor bolt itself or the reference core shaft of the anchor bolt unit is in a vertical state and rises to a position that coincides with the core ink, and holds them until the concrete is hardened. Swing type based on holding in a vertical state by means Nkaboruto is a precision positioning method of anchor bolts to the foundation by.
[0033]
The present invention is basically configured as described above, and anchor bolt positioning is performed according to the same principle. More specifically, positioning of a single anchor bolt and a plurality of anchor bolts are performed. The positioning of the anchor bolt unit connected in a predetermined positional relationship can be divided into the positioning of the former single anchor bolt by placing the foundation concrete into the base part and the rising part in two stages, or dividing It is further divided into two depending on whether it is performed in one step.
[0034]
As described above, the difference between the positioning of the single anchor bolt and the positioning of the anchor bolt unit in which a plurality of anchor bolts are combined is that vertical adjustment after placing concrete is performed, and the former is performed on the anchor bolt itself. On the other hand, the latter is a point to be performed on the reference core shaft configured in the unit. However, the latter is a method in which a plurality of anchor bolts are grouped together for efficient positioning, and the mutual principle of mutual positioning is not different.
[0035]
In addition, when positioning the single anchor bolt and placing concrete in two stages, in the case of the outer periphery of the solid foundation, the portion other than the outer periphery of the solid foundation and other foundations (cloth foundation, Independent foundation, composite foundation, continuous foundation).
[0036]
In the case of placing concrete in two stages, in the case of parts other than the outer periphery of the solid foundation and other foundations, it is placed on the anchor bolt mounting means installed corresponding to the core of the discarded concrete. It is necessary to construct an extension shaft that extends beyond the top edge of the concrete for the base portion (concrete for the first stage placement), and the strength is not easily displaced even by the placement of the concrete for the base portion. On the other hand, in the case of the outer periphery of the solid foundation, it is not necessary even when placing concrete in two stages.
[0037]
When placing concrete in two stages, in the case of parts other than the outer periphery of the solid foundation and other foundations, anchor bolts are attached to the extension shaft protruding from the concrete for the base so that it can tilt. The concrete for the rising portion is placed and then the anchor bolt is adjusted to a vertical state before it is hardened, and the anchor bolt is held in a vertical state by the holding means until the concrete is hardened. In the case of all foundations except foundations, when placing concrete in one step, anchor bolts can be tilted according to the core of the discarded concrete, and both the base part and the rising part can be installed simultaneously. Place concrete, adjust the anchor bolts to a vertical position before they harden, and wait until the concrete hardens. It is intended to hold the vertical position by simple retention means.
[0038]
In the case of a solid foundation, concrete for the base part and concrete for the rising part will be placed in two stages. As in the case of placing concrete in one stage, the anchor bolt mounting means is not configured with an extension shaft, and the anchor bolt is tilted up from the anchor bolt mounting means, and then the base concrete is placed. . Since this concrete is deep enough to be buried in the middle of the anchor bolts on the outer periphery of the solid foundation, the inclination is corrected with a vertical tool before the concrete is hardened, and the anchor is secured by the holding means. Maintains the verticality of the bolt.
[0039]
In the solid foundation outer peripheral portion, when placing the concrete for the base portion, since the mold frame exists only on the outer frame side, at this time, as the holding means, two belt-like holding pieces connected to be bent in the middle, Adopting an anchor holding hole opened at the center of the bend and a magnetized part arranged near both ends of each belt-like holding piece, the anchor bolt that ensures verticality is covered with the anchor holding hole. At the same time, it is appropriate that the two belt-like holding pieces are opened in a V shape and can be attracted and fixed to the outer mold frame by the magnetized portions at both ends thereof. Since usually magnetic metal is used for these molds, it is possible to perform attraction bonding by this magnetized portion.
[0040]
At the outer periphery of the solid foundation, after the concrete for the base is hardened, the concrete at the rising part is placed, but at this point, the anchor bolt is securely fixed by the concrete at the base. , There is no need to fix by the holding means.
[0041]
In any of the above cases, the positioning principle is exactly the same. When placing concrete in two stages, in the case of other parts other than the outer periphery of the solid foundation and other foundations, when placing concrete at the rising part, the anchor bolt can be tilted freely on the extension shaft Therefore, if the extension shaft is kept in a vertical state and does not maintain the relationship that the top and bottom marks displayed on the discarded concrete are vertically aligned, the positioning of the anchor bolts mounted on the extension shaft is accurate. Sex is not secured. Therefore, as described above, the anchor bolt mounting means and its extension shaft to be mounted on the discarded concrete must be sufficiently strong so that no displacement occurs even when the base concrete is placed.
[0042]
However, in this case, since the thickness of the concrete for the base portion is much thinner than that of the rising portion, the pressure generated when placing the concrete is not so large. On the other hand, the extension shaft is a core on the discarded concrete. Since it is only necessary to play the role of extending the ink to the base concrete, it can be formed into a columnar shape or the like that is not so thick, and the pressure received by the concrete can be reduced. Therefore, the strength required for the anchor bolt mounting means and the extension shaft is not so great as to affect the cost.
[0043]
In any case, in the present invention, first, it is necessary to position the core for the anchor bolt or the core for the reference core shaft of the anchor unit on the discarded concrete and display it. .
[0044]
The discarded concrete is arranged in advance with a sufficient width along the entire construction area of the foundation or along the installation line of the rising portion.
Furthermore, on the discarded concrete, a core ink for the anchor bolt or a core ink for the reference core shaft of the anchor bolt unit is positioned directly from the building reference core, and this is literally displayed with black ink or other marking means. Shall. It is also possible to position the reference core line at the rising edge of the foundation from the building reference core, discard it and display it on the concrete, and position the anchor bolt core ink etc. based on this reference core line .
[0045]
In this case, the reference core line to be matched with the reference core line of the rising portion of the foundation and the core for the anchor bolt or the core for the reference core shaft of the anchor bolt unit that has a predetermined positional relationship with the reference core line. Creating a displayed core ink display tape, and displaying the core ink by pasting the core ink display tape on the discarded concrete while matching the reference core lines with each other; You can also
[0046]
Next, as described above, when a single anchor bolt is erected on the discarded concrete, the anchor bolt attaching means is fixedly installed corresponding to the core ink. As described above, when placing concrete on a foundation other than a solid foundation and performing it for the base portion and the rising portion in two stages in sequence, the anchor bolt mounting means is provided with a base portion. Use an upright extension shaft that exceeds the thickness. Such an extension shaft is not necessary when the concrete is placed for the base portion and the rising portion at the same time.
The concrete is placed in two stages even in the part other than the outer periphery of the solid foundation. In the foundation other than the solid foundation, the base part and the rising part are sequentially two stages. This is exactly the same as in the case of.
[0047]
As described above, the anchor bolt mounting means needs to be higher in strength than that in the case where the concrete is placed in two stages, except that point. There is no reason to make a difference in the configuration itself. In any case, various configurations can be freely employed while maintaining a necessary mounting strength.
[0048]
For example, an all-anchor that has a mounting hole formed in abandoned concrete and is driven into and fixed thereto and a shaft member coupled thereto, and a shaft member provided with a coupling means for a hinge part or a height adjustment part described later. A pedestal fixed on abandoned concrete with an adhesive, a concrete nail or a concrete screw, a nut member fixed on the base, and a bolt member screwed to the nut member, the hinge portion or the height A structure comprising a bolt member provided with a coupling means with the height adjusting portion, or a base fixed on an abandoned concrete with an adhesive, a concrete nail or a concrete screw, a hollow bolt member fixed thereon, and the hollow A cap nut member that is screwed into the bolt member, and includes a cap nut member that includes a coupling means with a hinge portion or a height adjustment portion, which will be described later. It can be.
[0049]
Alternatively, it is a pedestal fixed on abandoned concrete with an adhesive, a concrete nail or a concrete screw, one of the coupler joints fixed on the base, and the other of the coupler joints detachably coupled to one of the coupler joints. The structure consisting of the other part of the coupler joint provided with the hinge part or the height adjusting part described later, or a screw to be screwed after a mounting hole is drilled in the discarded concrete and a plug material is press-fitted into this The structure etc. which consist of a member and the connection means with the postscript hinge part or height adjustment part comprised integrally at the upper end can also be employ | adopted.
[0050]
In addition, it is appropriate that each of the above pedestals has a peep hole opened at the center thereof, and when it is discarded and installed on the concrete, it can be attached while checking the core ink. Also, if two sector-shaped projecting pieces are formed in this peephole so that their vertices face each other, when the pedestal is discarded and placed on the concrete, the intersecting reference core displayed on it is displayed. By arranging the sides of the two sector-like projecting pieces in the peephole of the pedestal along the intersecting reference core line on the line, the cores can be more accurately aligned with each other.
[0051]
In addition, in the case of concrete two-stage placing, the extension shaft that rises up to the attachment means must ensure its verticality as described above, and this is measured at the time of installation. Must be adjusted to hold it. This can be done with a variety of vertical instruments, and there is no reason to rely on it, but in order to do it more efficiently, a pipe that can be smoothly and almost loosely sheathed on the extension shaft A vertical instrument composed of a body and a vertical measuring unit configured at the upper end of the body can be used.
[0052]
Although it is possible to freely adopt the vertical measuring unit with appropriate accuracy, it is preferable that it is as simple as possible. For example, it is possible to employ a configuration in which the verticality is measured by positioning the air ball in the liquid at the center of the upper surface.
[0053]
Further, as described above, the pipe body should have a diameter that can be smoothly and almost externally mounted on the anchor bolt to be measured, that is, an inner diameter slightly exceeding the diameter of the anchor bolt to be measured. Is appropriate. In order to achieve smoother insertion / removal, the inner diameter of the pipe body is formed slightly larger than the outer diameter of the anchor bolt or the like to be measured, and the inner diameter of the pipe body is axially extended over the entire inner circumference at regular angular intervals. It is appropriate to form a plurality of ridges along. In this case, the diameter of the circular arc connecting the tops of the plurality of protrusions is slightly larger than the outer diameter of the anchor bolt or the like to be measured. Since the area of the portion that comes into contact with the outer periphery of the anchor bolt or the like during the exterior is reduced, smoother insertion / removal can be realized. Furthermore, it is convenient to form the lower end of the pipe body in a smooth downward spread, because an action of guiding the upper end of the anchor bolt or the like toward the center occurs when the anchor body is mounted on the anchor bolt or the like.
[0054]
In addition, the pipe body of this vertical device has its inner diameter adjusted to the diameter of the object to be measured with the maximum outer diameter, and for a measurement object having a smaller diameter, an adapter is inserted into the pipe body. It is appropriate to make it possible to cope with this by using it. The adapter has an outer diameter corresponding to the inner diameter of the pipe body, and an inner diameter corresponding to the outer diameter of the measurement target. As with the inner periphery of the pipe body, it is convenient for the smooth insertion and removal of the measurement object to form a plurality of protrusions on the inner periphery. In addition, it is appropriate that an annular casing is provided on the outer periphery of the lower end and that the inlet at the lower end is smoothly spread downward.
[0055]
As can be understood from the above description, the above vertical instrument is not only for measuring the verticality of the extension shaft, but also for the verticality of the anchor bolts raised from the extension bolt or the anchor bolt mounting means on the discarded concrete. It goes without saying that the verticality of the reference core shaft of the anchor bolt unit is also used for measurement and the like. Of course, it can be used in various other cases.
[0056]
Thereafter, when the concrete is placed in two stages, the concrete for the base portion is placed. Of course, it is a premise that the mold for the base part is separately installed. The concrete for the base portion is placed up to a position immediately below the upper end of the extension shaft raised from the anchor bolt mounting means. Needless to say, this is because the length of the extension shaft is set.
[0057]
Next, when the concrete for the base portion is cured to some extent, an anchor bolt is raised at the upper end of the extension shaft via a hinge portion. If necessary, in addition to the hinge portion, a height adjusting portion is interposed directly above or directly below the hinge portion. In the above description, the anchor bolt is attached so that the extension shaft and the mutual axis coincide with each other.
[0058]
The hinge portion is a means that can be bent in any direction of 360 degrees at this portion, but is not limited to a specific configuration as long as it has such an action. For example, the hinge portion can be formed of a flexible tube material whose both ends are insertion coupling ends. In this case, a connecting portion such as a bamboo shoot or a spiral is formed on the upper end of the extension shaft and the lower end of the anchor bolt, respectively, and each is inserted from the corresponding end portion of the tube material and connected. it can. The connection can be reinforced by a band or the like as necessary. The same applies to the case where a hinge portion is interposed between the anchor bolt mounting means and the anchor bolt. In this case, a means such as a connecting rod is set up at the upper part of the former, and similarly at the upper end and the lower end of the latter. A joint portion such as a bamboo shoot shape or a spiral shape is formed and can be joined in the same manner.
[0059]
In addition, the hinge portion may be formed of a flexible multi-layered rubber pillar or other elastic material whose both ends are joint ends. Of course, the elastic material can be a single-layer rubber pillar or the like. The hinge part of this structure is suitable when it interposes between the anchor bolt unit which sets a plurality of anchor bolts collectively, and its attachment means. Of course, depending on this size, it may be suitable to be interposed between one anchor bolt and the extension shaft or mounting means.
[0060]
Moreover, the said height adjustment part is a means for adjusting the height of an anchor bolt, and if this is possible, it will not be limited to a specific structure. For example, the height adjustment part is a turnbuckle type comprising an adjustment part main body that is rotated to adjust the length, and screw members having spirals opposite to each other that are screwed into the adjustment part main body from both ends. Can be configured to that of the mold.
[0061]
Alternatively, a cylinder-shaped adjustment part main body, two piston members inserted so as to be able to advance and retreat from both ends thereof, and rod members connected to the two piston members and projecting from both ends of the cylinder-shaped adjustment part main body, Two or more fixing screws screwed into the peripheral side of the cylinder-shaped adjusting portion main body, the piston type comprising two or more fixing screws that are screwed to the peripheral side of the piston member to fix the position thereof can do.
[0062]
An anchor bolt is raised on the extension shaft via a hinge part and, if necessary, a height adjusting part, and the height of the anchor bolt is adjusted as necessary. Place concrete. At this time, naturally, a separate formwork for the rising portion must be installed. In addition, this formwork is obtained by obtaining a line of a base width by a base width ruler based on the extension shafts at a plurality of locations, and is configured along this line. Thus, the mold can be constructed by efficiently measuring.
[0063]
The anchor bolt is subjected to a corresponding pressure by such concrete placement. As described above, the anchor bolt is coupled to the extension shaft through at least the hinge portion, and can be bent in any direction of 360 degrees. It inclines at the site, releases most of the pressure, and no large external force is applied to the extension shaft. Therefore, the extension bolt and the anchor bolt mounting portion at the lower end thereof maintain the state when they are installed on the discarded concrete, and the extension shaft maintains the state where the vertical bottom core has been accurately moved to the upper end. ing.
[0064]
Next, immediately, that is, before the concrete hardens, a vertical device is set at the upper end of the anchor bolt, and the anchor bolt is returned to the vertical state while checking with a vertical measuring unit of the vertical device. Hold by holding means until concrete hardens. If the vertical instrument is left set on the anchor bolt, it is convenient that the verticality can be easily confirmed during the inspection.
[0065]
The holding means holds the concrete until it hardens, and thereafter, a large external force is not applied unless there is a special case, so that the holding means can be held by a simple holding means. For example, it is possible to use a holding device having two belt-shaped holding pieces that can be bent at the center and having an anchor holding hole opened at the center of the bending. It is appropriate to arrange magnets near both ends so that they can be fixed to the iron-based magnetic metal mold.
[0066]
When this holding means is used, an anchor holding hole is sheathed near the upper end of the anchor bolt, and both ends of the two holding pieces are attracted and fixed to the upper end of the mold by magnets disposed on the anchor holding hole. Hold vertical. The holding means has its both ends adsorbed and fixed to the upper ends of the molds on both sides in a state in which the holding means is spread out on a substantially straight line, or is bent in a V shape and has its both ends at the upper ends of the one mold Adsorb and fix to.
[0067]
On the other hand, in the case of cloth foundations and other foundations (excluding solid foundations), when performing concrete in a one-step placement process in which the concrete is placed on both the base part and the rising part at once, as described above. The anchor bolt is attached to the anchor bolt attachment means attached corresponding to the core ink on the discarded concrete, and the anchor bolt is coupled via the hinge portion and, if necessary, the height adjustment portion. Needless to say, the anchor bolt should be arranged in the vertical state so that its axial center coincides with the core ink.
[0068]
The hinge part and the height adjusting part are as described above, and the manner of mutual coupling is also the same.
[0069]
After that, concrete for the base portion and the rising portion of the foundation is cast at a time, and the anchor bolt tilted thereby is returned to the vertical position using the vertical device before hardening, and the anchor in the vertical state is further restored. The bolt is held by the holding means as described above until the concrete is hardened. The holding means and the holding method are the same as described above.
[0070]
Whether the concrete is placed in two stages or in one stage, as described above, the holding means holds the vertical state, but the holding means assists until the concrete is hardened. Therefore, it is simple and does not interfere with the adjustment of the top level of the foundation rising portion.
[0071]
After the concrete is hardened, the holding means is removed from the anchor bolt, and if the vertical instrument is left set, it is also removed. If the anchor bolt is kept in a vertical state at this point, its axis and the core on the discarded concrete should be in a vertical relationship. Therefore, it is positioned and attached accurately.
[0072]
In the case of the outer periphery of a solid foundation, as mentioned above, concrete placement is in two stages, one for the base part and one for the rising part. How to attach the anchor bolt to the anchor bolt attachment means Is the same as the case of placing concrete in one stage in the case of cloth foundations and other foundations (excluding solid foundations). After the anchor bolt is tilted up to the anchor bolt mounting means via a hinge portion or the like, the concrete for the base portion is placed.
[0073]
Since concrete reaches the middle of the anchor bolt at the outer periphery of the solid foundation, a vertical tool is set at the upper end of the anchor bolt before it hardens, and the anchor bolt tilted by placing the concrete vertically Correct it. Use a vertical tool to check whether or not it is vertical. The anchor bolt that secures the verticality in this way holds its vertical state by the holding means as described above.
[0074]
After the concrete for the base portion is hardened, the holding means is removed and the concrete for the rising portion is placed. At this time, as described above, since the anchor bolt is firmly held by the concrete for the base portion, it is not inclined even by placing the concrete for the rising portion.
[0075]
Thus, the anchor bolt can be positioned and erected accurately even in the outer peripheral portion of the solid foundation with a very simple operation.
[0076]
When setting up an anchor bolt unit in which a plurality of anchor bolts are gathered on the discarded concrete, firstly fix the unit mounting means for mounting the anchor bolt unit corresponding to the core ink for the reference core shaft. To do.
[0077]
The anchor bolt unit is a unit using a support plate material such as a template in a mutual positional relationship when a plurality of anchor bolts are attached to the foundation, and the reference core shaft has the positional relationship of the anchor bolts described above. The reference core shaft is disposed in the anchor bolt unit in a positional relationship that can be realized in the foundation when the reference core shaft is discarded in a vertical state and disposed on a concrete core.
[0078]
Thus, when the anchor bolt unit is attached to the unit, and the anchor bolt and the reference core shaft are placed in a vertical state, the axis of the reference core shaft is discarded and the corresponding core ink on the concrete is Position them so that they match, and fix them at these positions.
[0079]
Then, the anchor bolt unit is attached to the unit mounting means, and the hinge of the reference core shaft coincides with the core ink when the anchor bolt or the like is raised in the vertical state as described above, and the hinge It attaches via a height adjustment part as needed.
[0080]
In order to prevent the anchor bolt unit from being tilted more than necessary in the above state, the auxiliary leg is suspended from a support plate material such as a template that supports the anchor bolt while positioning it, and thereby, the above-described necessity is exceeded. It is preferable to be in charge of an inclination preventing action for preventing the inclination of the above.
[0081]
After that, concrete for the base portion and the rising portion of the foundation is placed simultaneously, and the anchor bolt unit tilted at that time is adjusted to a vertical state before the concrete is hardened. This may be achieved by setting the vertical instrument on the reference core shaft and moving it to ensure its verticality. Since the reference core shaft is arranged in parallel with all the other anchor bolts in the unit, the verticality of all the other anchor bolts can be ensured by correcting it vertically.
[0082]
The reference core shaft thus adjusted vertically is held in the vertical state by the holding means until the concrete is hardened. As the holding means, those described above can be used, and the usage is naturally the same. Further, as described above, since it is a simple holding means, there is almost no hindrance to the level adjustment of the top of the foundation. If the vertical device is set on the reference core shaft, it is convenient that the verticality can be confirmed during the inspection.
[0083]
After the concrete is hardened, the holding means is removed and the upper template is also removed. Pull out the reference core shaft or cut it at the top edge level of the foundation riser. If a vertical instrument is set, remove it. When the reference core shaft is composed of a shaft main body constituting the outer layer and a small-diameter core member constituting the axis thereof, and can be cut at any part in the length direction. Should be cut at the top level of the rising edge of the foundation as described above. At this time, even if the reference core shaft is cut at any part in the height direction, a small-diameter core member constituting the axis appears on the end face, and this is displayed on the top end of the foundation rising portion thereafter. It can be used as the origin of the reference core line to be performed. In addition, it is preferable that the core member has a different color from the outer layer because of good visibility.
[0084]
When positioning is performed using such an anchor bolt unit, a plurality of anchor bolts can be positioned at a time, which is efficient. As long as the reference core shaft maintains the verticality, the positioning of each anchor bolt is accurately performed as understood from the above description.
[0085]
In any of the above cases, there is a work process in which the anchor bolt tilted by the concrete pouring pressure is returned vertically after the concrete is placed and before the concrete is hardened, which is the most important process. In this work process, when using a vertical instrument consisting of a pipe body that can be mounted on the anchor bolt or the reference core shaft as described above and a vertical measuring unit configured at the upper end thereof, the anchor bolt to be measured And the reference core shaft must have an accurate circular shape centered on the axis when viewed from the upper end. If it is eccentric, if the pipe body of the vertical instrument is mounted on its anchor bolt or the like, it will tilt in the eccentric direction, and it will be difficult to ensure the correct verticality of the anchor bolt or the like. It is.
[0086]
The reference core shaft is manufactured for that purpose, and of course, when viewed from the upper end, it is configured to form an accurate circle centered on its axis, The anchor bolt uses a commercially available one, and in many cases, the screw portion at the upper end is not accurately manufactured. In many cases, the outer edge of the spiral that constitutes the upper threaded portion protrudes partially and does not form a circle centered on the axis when viewed from the upper end side. Therefore, if it remains as it is, it cannot be accurately measured whether or not it has become vertical by the vertical instrument.
[0087]
Therefore, for such an anchor bolt, in advance, in a factory or the like, including the upper threaded portion, at least about the portion where the pipe body of the vertical device is exteriorized, the pipe body is not eccentric, without loosening, In order to provide a smooth exterior, it should be used that which has been modified so as to have a circular shape centered on the axis when viewed from above. This processing can be performed by deleting a portion protruding more than necessary by turning or the like. An irregular shaped anchor bolt can be used by performing such processing.
[0088]
In addition, when the hinge portion is made of a flexible tube material whose both ends are insertion coupling ends, and the bamboo shoot-like connecting portion is inserted and connected to the upper and lower ends, the bamboo shoot-like connecting portion is also Similarly, when viewed from the plane, the outer periphery needs to draw an accurate circle centered on the axis, and is not allowed to be eccentric. The same applies to the case where the height adjusting unit is employed and is configured with a mechanism such as a turnbuckle. The upper and lower bolt members are configured without eccentricity, and the mutual bolt members are accurately located on the same axis. It is necessary to be arranged in.
[0089]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0090]
<Example 1>
The first embodiment relates to positioning of anchor bolts installed on a concrete foundation of a wooden building, and in particular, hole down anchor bolts, anchor bolts installed at a position close to a brace, and anchor bolts installed at a base joint part. Suitable for installing anchor bolts that require high accuracy. Of course, there is no problem even if it is used for positioning of all other anchor bolts.
[0091]
First, the core ink for the anchor bolt to be installed using this method on the discarded concrete is positioned and displayed. The discarded concrete is arranged in advance in a necessary range in the foundation construction area.
[0092]
Such anchor bolt core ink shall be positioned directly from the separately set and displayed building reference core on the discarded concrete, and this shall be displayed literally with ink or other marking means. . This positioning can be easily performed using a measuring instrument such as a transit. Positioning using such a transit etc. is performed only for the main part such as the reference core line of the rising part of the foundation, and the anchor bolt core ink etc. may be positioned by measuring with reference to these reference core lines. it can.
[0093]
In this case, the core mark for the anchor bolt and the reference core shaft of the anchor bolt unit is positioned using the core mark display tapes t1 to t6 as shown in FIGS. 16 (a) to (f), and The display is speedy and accurate. These core ink display tapes t1 to t6 are the reference core lines L1 and L2 to be matched with the reference core line positioned by transit or the like, and the core ink ca and anchor bolt for anchor bolts having a predetermined positional relationship therewith. The core ink cs for the reference core shaft of the unit is displayed. As can be understood from the above description, the core marking tapes t1 to t6 are in a state in which the reference core lines L1 and L2 are discarded and matched with the reference core lines that are positioned and displayed on the concrete. By pasting, the cores ca, ca... And cs, cs.
[0094]
Next, in the first embodiment, anchor bolts are installed by using anchor bolt cores ca, ca... Positioned and displayed on the discarded concrete as described above. First, a fixture (anchor bolt mounting means) 1 composed of a hollow bolt 1b with a base 1a is fixedly set in correspondence with the corresponding core ink ca. As shown in FIG. 1 (a) and FIG. 14, the pedestal 1a has a peephole 1c at the center, and the two sector-shaped projecting pieces 1d and 1d are placed at the top of the peephole 1c. A plurality of screw holes h, h... That also serve as bonding holes for adhesives are formed on the outside of the hollow bolt 1b so as to protrude in an opposing state, and the reference core line is provided on each side. A V-shaped notch v is formed in the center to be matched with L1 and L2, and a notch groove m is formed in the vicinity of each corner to cut it into a triangle.
[0095]
As shown in FIG. 1 (a), the fixture 1 is placed on the discarded concrete 2, and the peephole 1c is looked into from above, and the intersecting reference core lines L1, L2 displayed thereon are displayed. One or both of the sides of the two sector-shaped projecting pieces 1d and 1d in the peep hole 1c are arranged along both or one of the two or one or only the core line of the core ink ca. In this way, the hollow bolt 1b of the fixture 1 can be installed very accurately in alignment with the core ink ca.
[0096]
The mounting 1 is fixed to the discarded concrete 2 by using an adhesive and concrete screws 3, 3.
[0097]
Next, as shown in FIGS. 1A and 1B, the anchor bolt 6 is raised on the hollow bolt 1 b of the fixture 1 through the hinge portion 4 and the turnbuckle portion (height adjustment portion) 5.
[0098]
As shown in FIGS. 1 (a) and 1 (b), the hinge portion 4 is made of a flexible tube material, and a bag that is screwed into the hollow bolt 1b is inserted into the insertion coupling end at the lower end. A bamboo shoot-like connecting portion 7a that is raised at the center of the upper end of the nut 7 is inserted and coupled. Is inserted and combined.
[0099]
As shown in FIGS. 1 (a) and 1 (b), the turnbuckle portion 5 includes a turnbuckle portion main body 5b in which internal threads are formed in opposite directions at the upper and lower inner circumferences, and the turnbuckle portion main body from the lower end. The screw member 5a is screwed to 5b and the screw member 5c is screwed to the turnbuckle main body 5b from the upper end. The two screw members 5a and 5c are male screw members having spirals in opposite directions, and are naturally male screw members having spirals corresponding to the female screws at the upper and lower portions of the inner periphery of the turnbuckle body 5b. The upper screw member 5c has its upper end fixed to the lower end of the anchor bolt 6.
[0100]
As shown in FIGS. 1 (a) and 1 (b), the anchor bolt 6 is provided with a retaining body 6a immediately above the lowermost part and a male screw 6b at the uppermost part, and the male screw 6b has a male screw 6b. The nut 6c is screwed in advance.
[0101]
As described above, the anchor bolt 6 has the turnbuckle portion 5 and the hinge portion 4 coupled to the lower end thereof in this order from above, and the cap nut 7 coupled to the lower portion of the anchor bolt 6 is attached to the fixture 1. By being screwed into the hollow bolt 1b, it rises on it. In this way, as shown in FIG. 1 (b), the anchor bolt 6 is raised with its axial center aligned with the corresponding core ink ca.
[0102]
Thereafter, if necessary, the turnbuckle portion main body 5b of the turnbuckle portion 5 is rotated to adjust the height of the anchor bolt 6, and then concrete is placed. This Example 1 is an example relating to an integral placing in which the concrete for both the base portion and the rising portion is placed in a single stage, and the concrete is placed in such a manner.
[0103]
The anchor bolt 6 receives a corresponding pressure by such concrete placement. As described above, the anchor bolt 6 is coupled to the hollow bolt 1b of the fixture 1 via the hinge portion 4, and the hinge portion 4 is made of a flexible tube material. This portion can be bent in any direction of 360 degrees. Therefore, as shown by a one-dot chain line in FIG. 2, the portion is inclined to the corresponding side by the placement pressure of the concrete 8. .
[0104]
Further, since it is inclined according to the driving pressure in this way, most of the pressure can be released at this portion, and as a result, an external force larger than necessary is applied to the hollow bolt 1b and the pedestal 1a coupled therethrough. Will not be added. Therefore, the fixture 1 can reliably hold the state at the time of installation on the discarded concrete 2.
[0105]
Next, immediately before the concrete 8 is hardened, the vertical tool 9 is immediately set on the upper end of the anchor bolt 6 and, as shown in FIG. 6 is returned to the vertical state, and as shown in FIG. 3, the state is held by the vertical holder (holding means) 10 until the concrete 8 is hardened. The vertical device 9 is set in the state where it is set on the anchor bolt 6. The purpose of this is to make it possible to immediately confirm the verticality during subsequent inspections.
[0106]
As shown in FIG. 19 (a), the vertical device 9 is composed of an upper vertical measuring portion 9a and a pipe body 9b for exterior mounting to the anchor bolt 6 or the like. The vertical measuring unit 9a employs a configuration that measures verticality by positioning an air ball in the liquid at the center of the upper surface. Further, the pipe body 9b is formed so that its inner diameter is slightly larger than the outer diameter of the anchor bolt 6 to be measured and, as shown in FIG. A plurality of protrusions along the axial direction are formed. The diameter of the circular arc connecting the tops of the plurality of protrusions is such that it slightly exceeds the outer diameter of the anchor bolt 6 to be measured. Further, the lower end of the pipe body 9b has a shape that smoothly expands downward as shown in FIG. 10 (a).
[0107]
As shown in FIGS. 2 and 3, the vertical device 9 can be easily and reliably set on the anchor bolt 6 by covering the pipe body 9 b on the upper end of the anchor bolt 6. Then, after setting the vertical device 9 in this way, the anchor bolt 6 is moved in the direction opposite to the inclination direction, that is, in an upright state, and the verticality is confirmed by the vertical device 9 and is still vertical. If not, the accurate vertical state of the anchor bolt 6 can be ensured by slightly repeating the operation of making fine adjustments in the direction opposite to the inclination direction that can be read from the vertical device 9 and further confirming.
[0108]
As shown in FIGS. 18 (a) to (d), the vertical holder 10 includes two belt-like holding pieces 10a and 10a that can be bent at the center, and an anchor holding hole 10b that is open at the center of the bending, The belt-shaped holding pieces 10a and 10a are composed of magnets 10c arranged in the vicinity of both ends.
[0109]
  The vertical holder 10 raises the anchor bolt 6 to a vertical state, and then the anchor holding hole.10b3 and FIG. 18 (c), the belt-like holding pieces 10a and 10a are spread almost linearly, and magnets at both ends thereof are covered.10c, 10cIs fixed to the upper ends of the molds k, k on both sides, so that the vertical state of the anchor bolt 6 is maintained.
[0110]
  The vertical cage 10 has an anchor retaining hole.10bThen, the anchor bolts 6 are externally mounted, and as shown in FIG. 18 (d), the belt-like holding pieces 10a and 10a are bent into a substantially V shape, and magnets at both ends thereof.10c, 10cCan be held at the upper end of one mold k by holding the anchor bolt 6 in its vertical state.
[0111]
The vertical cage 10 is only for holding the anchor bolt 6 until the concrete 8 is hardened, and is very simple, but it is not expected that a large external force will be applied between them. It is enough. Further, since the vertical cage 10 has such a simple configuration, it does not interfere with the adjustment of the top end level of the basic rising portion.
[0112]
After the concrete 8 is hardened, the vertical cage 10 and the vertical device 9 are removed from the anchor bolt 6. The anchor bolt 6 should be in a vertical state at this point, and if so, the axial center of the anchor bolt 6 and the core ink ca on the discarded concrete 2 should be in a vertical relationship. Therefore, it is positioned and mounted with high accuracy by an extremely simple mounting operation. FIG. 4 shows this state.
[0113]
<Example 2>
The second embodiment relates to the positioning of the anchor bolt 6 when the foundation is constructed by two-stage placement of concrete for the base portion and the rising portion.
[0114]
The core inks ca, ca..., Cs, cs... Are positioned and displayed on the discarded concrete 2 in exactly the same manner as in the first embodiment.
[0115]
Also in the second embodiment, the fixture 1 composed of the hollow bolt 1b with the base 1a similar to the first embodiment is installed in correspondence with the corresponding core ink ca. The method of positioning the fixture 1 in this case is the same as that described in the first embodiment. However, in Example 2, it is required that the verticality of the hollow bolt 1b rising from the fixture 1 is more accurate. In this case, the pedestal 1a is positioned and temporarily fixed as shown in FIG. 6 (a), and then the cap nut 7 with the extension shaft 7b upright on the upper surface is screwed onto the hollow bolt 1b. Further, as shown in FIG. 6 (b), a vertical device 9 is set on the extension shaft 7b, and the mounting state of the base 1a is adjusted so that the verticality of the extension shaft 7b can be secured. .
[0116]
If it is found that the pedestal 1a is tilted by measurement by the vertical instrument 9, an appropriate plate member is inserted into a necessary portion between the lower surface of the pedestal 1a and the upper surface of the discarded concrete 2 or the like. Adjust this. For example, as shown in FIG. 14, by using a cut groove m at the corner of the pedestal 1 a, a triangular portion of the corner is cut off, and this is separated between the lower surface of the pedestal 1 a and the upper surface of the discarded concrete 2. It can also be used as a member to be inserted into a necessary site. After securing the verticality of the extension shaft 7b in this manner, the pedestal 1a is surely discarded and fixed on the concrete with a concrete screw and an adhesive.
[0117]
Then, as shown in FIG. 7, the concrete 18 for base parts is laid. As shown in FIG. 7, the concrete 18 for the base portion is driven to a position immediately below the upper end of the extension shaft 7 b raised from the cap nut 7 screwed into the hollow bolt 1 b. The length of the extension shaft 7b should be set as such.
[0118]
In FIG. 7, the vertical device 9 is set at the upper end of the extension shaft 7b, which is for checking the verticality of the extension shaft 7b. Since the concrete 18 for the base portion is thin, the extension shaft 7b does not tilt at this stage if it is fixed to a certain extent.
[0119]
Next, when the base portion concrete 18 is hardened to some extent, as shown in FIG. 8, the anchor bolt 6 is raised at the upper end of the extension shaft 7 b via the hinge portion 4 and the turnbuckle portion 5. FIG. 5 shows an overall view of the combined state at this time. The hinge part 4 and the turnbuckle part 5 have the same configuration as that of the first embodiment. On the other hand, as shown in FIG. 8, the upper end of the extension shaft 7b is formed with a bamboo shoot-like connecting portion 7a, which is inserted into the insertion coupling end at the lower end of the hinge portion 4 and coupled. The anchor bolt 6 can be raised.
[0120]
Thereafter, if necessary, the turnbuckle portion main body 5b of the turnbuckle portion 5 is rotated to adjust its length (height), and as shown in FIG. Concrete 28 is placed.
[0121]
As described in the first embodiment, the anchor bolt 6 is subjected to the placement pressure by the placement of the concrete 28 and is inclined at a position corresponding to the pressure at the portion of the hinge portion 4. Then, the driving pressure is released, and as a result, an unnecessary external force is not applied to the extension shaft 7b, and the extension shaft 7b is in a state where the core ink ca in the vertically lower position is accurately moved to the upper end. keeping.
[0122]
Next, as in Example 1 and as shown in FIG. 9, before the concrete 28 is hardened, the vertical device 9 similar to that of Example 1 is immediately set on the upper end of the anchor bolt 6, and the The anchor bolt 6 is returned to the vertical state while checking with the vertical unit 9 and the state is held by the vertical holder 10 until the concrete 28 is hardened. This vertical cage 10 is also the same as that described in the first embodiment, and the vertical state of the anchor bolt 6 can be held in the same manner. In this case, the vertical device 9 is also set in the anchor bolt 6 in this case.
[0123]
The subsequent operation is exactly the same as that described in the first embodiment, and the anchor bolt 6 should be kept in the vertical state at this time, and if so, as described in the first embodiment. Furthermore, since the shaft center and the core ink ca on the discarded concrete 2 should be in a vertically matching relationship, the anchor bolt 6 is accurately positioned on the foundation by a very simple mounting operation. It will be attached.
[0124]
<Example 3>
This Example 3 is related to the positioning of the anchor bolt 6 in the case where the foundation is constructed by the two-stage placement of the concrete for the base part and the rising part, as in Example 2, and Example 2 The process from the positioning display of the core inks ca, ca... And cs, cs... To the discarded concrete 2 to the rising and fixing of the extension shaft 7b is different. Since only the above process is different, only that will be described.
[0125]
As shown in FIG. 10 (a), a mounting hole hm is formed with a drill d so as to match the corresponding core ink ca of the discarded concrete 2, and a plug is inserted into the mounting hole hm as shown in FIG. 10 (b). The material p is press-fitted and fixed. Next, as shown in FIG. 10 (c), a screw member 1e as an anchor bolt attaching means is provided at the lower end, and an extension shaft 7b in which a housing 1f is arranged at the boundary with the screw member 1e is installed in the attachment hole hm. To do. As shown in FIG. 10 (d), this is performed by screwing the screw member 1e into the mounting hole hm using a cross groove 7c formed at the upper end of the extension shaft 7b. At this time, the screw member 1e is fixed by screwing into the plug material p as shown in FIG. 10 (c).
[0126]
Thus, as shown in the figure, the extension shaft 7b rises on the corresponding core ink ca on the discarded concrete 2. Next, as shown in FIG. 11, a reinforcing pipe 11 with a reinforcing rod 11a projecting in the circumferential direction at the lower end is sheathed, and as shown in FIG. 12, a vertical device 9 is further set on the reinforcing pipe 11, and the reinforcing pipe 11 The reinforcing rod 11a is discarded and fixed on the concrete 2 while confirming the verticality of the extension shaft 7b reinforced with the exterior. This verticality is secured by inserting a plate material or the like between the corresponding portion of the lower surface of the reinforcing bar 11a and the corresponding portion of the upper surface of the discarded concrete 2 as necessary. The reinforcing bar 11a is fixed using an adhesive and concrete nails or concrete screws 3, 3,.
[0127]
After the extension shaft 7b is thus secured in the vertical state and reinforced with the reinforcing pipe 11, the post-process is advanced in the procedure as described in the second embodiment. That is, after the concrete for the base portion is placed and the concrete is substantially cured, the extension shaft 7b is coupled to the lower end of the anchor bolt 6 via the turnbuckle portion 5 and the hinge portion 4 ( The extension shaft 7b is directly coupled by inserting the bamboo shoot-like connecting portion 7a into the insertion coupling end at the lower end of the hinge portion 4).
[0128]
<Example 4>
The fourth embodiment relates to an example in which an anchor bolt unit 16 in which a plurality of anchor bolts 6, 6...
[0129]
As shown in FIG. 13 (a), the anchor bolt unit 16 is a combination of upper and lower templates 12 and 12 in a mutual positional relationship when a plurality of anchor bolts 6, 6. is there. The upper and lower templates 12 have coupling holes opened in a positional relationship corresponding to the upper and lower sides, and the upper and lower ends of the anchor bolts 6, 6... Are inserted into the upper and lower templates 12, respectively. , 12 are fastened and fixed to the positions by nuts n, n screwed to the upper and lower positions.
[0130]
In the center of the template 12 above the anchor bolt unit 16, a coupling hole is opened. A nut n is inserted through the reference core shaft 13 and screwed into the portion at the upper and lower positions of the template 12. n is fastened and fixed. When the axis of the reference core shaft 13 is vertically aligned with the core ink cs, the axes of the anchor bolts 6, 6... In the unit respectively correspond to the discarded concrete 2. It is positioned so as to have a positional relationship corresponding to the top and bottom inks ca, ca.
[0131]
As shown in FIG. 13A, the reference core shaft 13 is composed of a shaft main body 13a constituting an outer layer and a small-diameter core member 13b constituting an axis thereof. Both the shaft main body 13a and the core member 13b are made of hard plastic that can be cut, and are colored in different colors.
[0132]
The anchor bolt unit 16 is coupled to a cap nut 7 that is screwed into the hollow bolt 1b of the fixture 1 via the turnbuckle portion 5 and the hinge portion 14.
[0133]
The turnbuckle portion 5 is the same as that described in the first embodiment. The upper end of the screw member 5c that is screwed into the upper part of the turnbuckle main body 5b is suspended and fixed at the center of the template 12 below the anchor bolt unit 16. That is, the drooping position of the screw member 5c is in a completely coincident relationship with the reference core shaft 13 in the vertical direction.
[0134]
The hinge portion 14 is composed of a flexible single-layer rubber column having both ends as coupling ends. The lower end of the screw member 5a below the turnbuckle portion 5 is provided at the center of the upper coupling end. It is fixed. Further, the upper surface of the cap nut 7 is fixed to the joint end of the lower portion of the hinge portion 14.
[0135]
Moreover, the said fixture 1 is a thing of the structure similar to what was demonstrated in Example 1. FIG. The cap nut 7 is the same as that described in the first embodiment.
[0136]
