BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical / horizontal detector provided with a level for detecting the horizontality and verticality of each member of a building under construction, and more particularly to a vertical / horizontal detection object. The present invention relates to a vertical / horizontal detector capable of accurately detecting the horizontal and vertical directions.

2. Description of the Related Art As a construction method of a residential building, there is a method of assembling a steel frame after foundation work and attaching an outer wall to the steel frame. Actually, an iron wall receiving member is fixed to a steel frame by fixing means such as bolts and nuts or welding, and then a panel-shaped pre-made outer wall member is fitted to the wall receiving member and fixed. Since the position of the wall receiving metal greatly affects the position of the outer wall member, it is necessary to accurately position the wall receiving metal. In other words, in order to make the outer wall of the building a uniform surface, it is necessary to prevent a step from occurring at the seam of the outer wall member, and therefore, it is necessary to finely adjust the amount of protrusion of the wall receiving hardware from the steel frame. It had been.

FIGS. 10 and 11 are views for explaining a conventional work of positioning (adjusting in and out) a wall receiving hardware. FIG. 10 is a longitudinal sectional view of a steel frame portion, and FIG. 11 is a top view of the steel frame portion. . As shown in FIG. 10, a wall receiving member 101 having an inverted T-shaped cross section and a wall receiving member 102 having an L-shaped cross section are attached to a steel frame 103 having an I-shaped cross section by a fixing tool such as a bolt and a nut. The steel frame 103 is arranged so as to be located at a joint between two outer wall members arranged in a vertical direction.
The normal direction of the cross section shown as 0 is the horizontal direction. The vertical receiving surface 105 of the wall receiving member 101 having an inverted T-shaped cross section abuts against the back surface of an upper outer wall member (not shown), and its horizontal surface 10.
6 supports the bottom surface of the outer wall member. Only the vertical surface 107 of the wall receiving member 102 having an L-shaped cross section abuts against the back surface of the lower outer wall member (not shown), and the wall receiving member 102 is located at the upper end of the lower outer wall member and thus supports the bottom surface. There is no.

In order to attach the wall receiving members 101 and 102 to the steel frame 103 so that a step does not occur between the upper and lower outer wall members, the vertical surfaces 105 and 107 are fixed so as to be located in the same vertical plane. There is a need. However, in the wall receiving member 101 having the inverted T-shaped cross section, the portion of the horizontal surface 106 protrudes outside the vertical surfaces 105 and 107. Therefore, when a normal level is applied, the portion of the horizontal surface 106 becomes an obstacle. . For this reason, it has not been possible to detect the verticality of the vertical surfaces 105 and 107 using a normal level.

Therefore, in the conventional construction method, FIG.
As shown in FIG. 0, the verticality of the vertical surfaces 105 and 107 is detected and adjusted using a plurality of water threads 100. These water threads 100 extend horizontally from the outer peripheral surface 108 of the outer wall corner member 104 arranged at the corner of the outer wall as shown in FIG. For example, in order for the wall receiving members 101 and 102 to be accurately positioned at different heights as shown in FIG. 10, the water thread 100 is stretched horizontally at the respective heights. By setting the distance α from the water thread 100 to a constant value at each height, the vertical surface in contact with the back surface of the outer wall member is arranged at a fixed position from the outer peripheral surface, and as a result,
The outer wall member is disposed so as to form a uniform outer wall surface without a step.

[0006]

However, in the conventional method as described above, first, the outer peripheral surface 10
A water thread 100 is stretched on the extension line of No. 8 and the wall receiving members 102 and 103 are measured while measuring the distance from the water thread 100, respectively.
The installation efficiency at the work site becomes worse,
It takes time and effort. The reference of the water thread 100 is the outer peripheral surface 108 of the outer wall corner member 104. However, when the outer wall corner member 104 is not vertical but is oblique, the embedding condition of the outer wall corner member 104 itself is not sufficient. If it is not good, a step will occur on the outer wall when the distance of the water thread 100 is adjusted. Furthermore, when there is no reference such as the outer peripheral surface 108 and there are irregularities on the surface of the steel frame, the level cannot be applied, and the wall receiving member is disposed at an accurate position. Not easy.

[0007] In view of the above problems, the present invention is intended to accurately and accurately detect the level and verticality of an object having irregularities, thereby improving construction efficiency. The purpose is to provide a detector.

[0008]

SUMMARY OF THE INVENTION A vertical / horizontal detector according to the present invention is a vertical / horizontal detector for detecting the vertical or horizontal position of an object having irregularities, and instructs a level body extending in one direction. A level formed as a part, a holding part attached to the level, and a leg fixed at the holding part with one end abutting on the object to be detected when the detector detects the level. It is characterized by the following.

According to one embodiment of the present invention, a magnet is provided at one end of the leg portion, and when the object to be detected is a material such as iron, the magnet is provided by the magnetic force from the magnet. The detector can be brought into contact with the object to be detected. The leg can be configured to be able to change the distance between its one end and the holding portion at a time other than at the time of the detection, and as an example,
Such a change in the distance can be performed from a change in the holding position held by the holding unit.

A graduation or a mark corresponding to the distance can be provided on both or one of the leg portion and the holding portion, and the horizontality and the verticality can be quickly detected by the graduation and the mark. When a leg is unnecessary in a part of the level, the leg is removed from the holding unit, or the holding unit is removed from the level, and the level itself is applied to an object to be detected. Can be used. The number of holding portions attached to the level can be selected according to the object to be detected, and a plurality of the holding portions can be attached, and each holding portion can hold the leg.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a vertical and horizontal detector according to the present invention will be described with reference to FIGS. The vertical / horizontal detector 10 according to the present embodiment includes a level 11 that can detect whether a detected portion is horizontal or vertical and a pair of levels that are detachably attached to the level 11 and hold the level 11 from both sides. Holding frames 12 and 12 and legs 13 extending from the holding frames 12 in a direction perpendicular to the direction in which the level 11 extends. These holding frames 12, 12 function as holding units.

The level 11 is a normal level 11 used for construction work at a construction site. The level 11 is provided with a pair of level indicators on a level body 16 which is a substantially rectangular parallelepiped and extends in the horizontal direction. 17 and 18 are embedded and provided. This level 11 can be used alone.
For example, when the bottom surface of the level 11 on the opposite side of the level indicating unit 17 is applied to a member to be measured for level, the level indicating unit 17 does not need the holding frame 12 and the legs 13 and the level indicating unit 17 is in contact with the member. Is horizontal or not. These level indicators 1
The structures of 7 and 18 are not particularly limited, and can take various configurations such as a type indicating whether or not the air bubble is horizontal from the position of a normal bubble or an electric signal.

The pair of holding frames 12, 12 are iron frames which are removably attached to the level 11 by means of thumb screws 21. FIG. 2 shows a side view of the holding frame 12.
The holding frame 12 is rectangular in cross section so that a band-like plate having a thickness of about 1 mm surrounds the level 11 in a plane perpendicular to the direction in which the level 11 extends.
The level 11 just fits at zero. At approximately the center of the plate-like portion 22 on the shorter side of the rectangle, the thumb screw 21 is screwed into a screw hole provided in the holding frame 12, and the thumb screw 21 is rotated by an operator. The thumb screw 21 advances and retreats with respect to the plate-like portion 22 on the short side, and the level 11 can be detachably attached. At the time of detection, the level of the level 11 is pushed by the bottom of the thumb screw 21 and becomes immovable with respect to the holding frame 12. This holding frame 12
The longer side of the cross-section rectangle is slightly longer than the longer side on the cross-section of the level 11, so that the attachment and detachment by the thumb screw 21 is performed in the space inside the frame formed thereby. The inside of the shorter side of the cross-section rectangle of the holding frame 12 has substantially the same length as the shorter side on the cross section of the level 11, but with some allowance for insertion and extraction into the hollow portion of the level 11. Is done.

A rectangular leg base 23 is formed on the outer side of the long side of the holding frame 12 on the side opposite to the side on which the screw 21 is provided, facing the end of the rectangular section. This leg base 2
3 is made of the same iron as the holding frame 12, and one surface of the leg base 23 is fixed to the outside of the holding frame 12 by welding, and the leg base 23 itself is integrated with the holding frame 12. The leg base 23 is a member for attaching the leg 13 to the holding frame 12. A screw hole 24 is formed at substantially the center of the leg base 23, the axial direction being a direction along the outside of the long side of the holding frame 12 and the direction normal to the bottom surface of the level 11.

The holding frame 12 having the leg base 23 is provided with a leg 13 made of a straight iron rod. Leg 13
Is formed with a flange-shaped contact portion 14 in which a magnet 19 is embedded in the bottom surface. The contact portion 14 can be attached to a material such as a steel frame by the magnetic force of a donut-shaped or disk-shaped magnet 19 embedded in the bottom surface, and the magnetic force has sufficient strength to support the entire vertical and horizontal detector 10. doing. The contact portion 14 is screwed to one end of the leg 13. The bottom surface of the contact portion 14 is located in a plane parallel to the bottom surface of the level 11 when the level 11 is attached. Therefore, the detection result can be displayed on the indicating portion 17 or 18 of the level 11 only by bringing the bottom surface of the contact portion 14 into contact with the object to be detected.

The other end of the leg 13 is threaded, and the threaded screw portion 26 is screwed into the screw hole 24 of the leg base 23.
To screw. A positioning nut 27 is previously engaged with the screw portion 26. When the leg 13 is screwed into the screw portion 26 and the nut 27 contacts the bottom of the leg base 23, the leg 13 does not move any further. The length of the leg 13 is determined. The nut 27 can be fixed within the threaded portion 26 or can be movable within the threaded portion 26 as needed. For example, when measuring the horizontality and verticality of a steel frame having irregularities of typical dimensions, it is only necessary to measure the dimensions of a certain pattern, so fixing the nut 27 improves the working efficiency, Simply by touching the vertical / horizontal detector 10, horizontality and verticality can be detected. Also, for example, there are various irregularities in one construction site, and when detecting them with one vertical and horizontal detector 10, the movable nut 27 can cope with various irregularities.

In this embodiment, the leg 13 is connected to the leg base 23 of the holding frame 12 by a screw. However, the leg 13 may be connected by another mechanical element. That is, a plurality of protrusions provided in the longitudinal direction of the leg are grooves (or vice versa).
A structure in which a plurality of holes are provided in the longitudinal direction of the leg, and a hole is fixed through one pin in the hole,
Various structures can be adopted, such as a structure of a rack and a pinion, a structure in which legs can slide or expand and contract, and a mechanism for stopping the slide or expansion and contraction. The magnet 19 at the bottom of the leg 13 can also have another shape other than the shape of a donut or a disk, and the leg 13 is not limited to a round bar but can have another shape such as a square pole or a hexagonal pole.

FIG. 3 is a perspective view showing a state where the vertical and horizontal detector 10 of the present embodiment is used. In this figure,
The vertical / horizontal detector 10 detects whether the horizontal plane 30 of the iron material 28 and the horizontal plane 31 of the iron material 29 are located in the same horizontal plane. Needless to say, since the vertical portion 32 of the iron material 29 protrudes downward from each of the horizontal planes 30, 31, it is not possible to detect the horizontality with a normal level. However, in the vertical / horizontal detector 10, the pair of legs 13, 13 reach the horizontal surfaces 30, 31, respectively, and the contact portions 14, 14, provided on one end side of the legs 13, 13, adhere to the horizontal surfaces 30, 31 by magnetic force. To fix the vertical and horizontal detector 10. The level 11 of the vertical / horizontal detector 10 detects whether or not the horizontal planes 30 and 31 are located in the same horizontal plane while straddling the vertical portion 32 with extremely high construction efficiency.

In the vertical / horizontal detector 10 of the present embodiment, the ordinary level 11 is formed by the thumb screws 21, 21 and the holding frame 12,
12 is fixed. By loosening the thumb screws 21 before and after measuring the uneven object, the level 11 can be removed from the vertical / horizontal detector 10 and used for detecting the uneven object. Therefore, one level 11 can be used in various places of the whole building irrespective of the presence or absence of unevenness.

In the present embodiment, the holding frame 12 and the level 11 are connected by the thumb screw 21, but may be connected by other mechanical elements. For example,
The level 11 may be provided with grooves or projections for fitting, or a magnet or iron piece may be provided, and the corresponding mechanical element may be formed on the holding frame 12. In this specification, it is assumed that such a modification of the level 11 is one of the ordinary levels 11 from the viewpoint that it can be used normally.

Next, another embodiment of the vertical / horizontal detector according to the present invention will be described with reference to FIGS. The vertical / horizontal detector 40 includes a level 41, which is indicated by a broken line in FIG. 4, and which can detect whether the detected portion is horizontal or vertical, and a level 41 which is detachably attached to the level 41 and has both sides thereof. And three holding frames 42, 42, 42 for holding at the central portion, and legs 43, 45, 43 extending from the holding frames 42 in a direction perpendicular to the direction in which the level 41 extends. Leg 4
5 has a longer longitudinal length than the leg 43.

The level 41 is a normal level 41 similar to the level 11 described above, and can detect horizontality and verticality by bringing the bottom surface into contact with an object to be detected. This level 41 is a pointing unit 49 embedded in the cuboid level body 50.
Having. Since the vertical / horizontal detector 40 has three holding frames 42, a level 41 having a shape elongated in the extension direction can be used. The holding frame 42 is removably attached to the level 41 with the thumb screw 46 in the same manner as the holding frame 12 described above.
It is attached so as to surround the periphery of.

Although the level 41 and the holding frame 42 have substantially the same configuration as the level 11 and the holding frame 12 of the above-described embodiment, the structure of the leg base 47 is different in this embodiment. The leg base 47 is integrated with a cylindrical iron member welded to the holding frame 42 at a position facing the bottom side of the holding frame 42. The leg base 47 is provided with a hollow portion whose axial direction is the normal direction of the bottom surface of the level 41, and the legs 43 and 45 are attached through the hollow portion. Although the diameter of the hollow portion is slightly larger than the outer diameter of the legs 43 and 45 and can be just inserted, the vertical and horizontal detector 40 detects horizontality and verticality. It has a diameter dimension that does not have.

A thumb screw 48 is attached to the leg base 47, and the legs 43 and 45 are held at least at the time of detection.
Fix for 2. By turning the thumb screw 48 and pressing the tip against each leg 43, 45, each leg 4
3. Fix 45. Conversely, when the thumb screw 48 is turned in the opposite direction, the legs 43, 45 are released from the tip of the thumb screw 48, and the legs 43, 45 become slidable in the hollow portion of the leg base 47, and the leg base 47 Can be removed from

Each of the legs 43 and 45 has a structure in which an abutting portion 44 is formed at one end of an iron round bar, and a magnet is provided on the bottom surface of the abutting portion 44 in the same manner as the leg 13 described above. Embedded. The other ends of these legs 43 and 45 are left as round bars,
This other end is inserted into the leg base 47 and the leg 43,
45 is retained. These legs 43 and 45 can freely change the length of the legs by sliding in the hollow portion of the leg base 47. Then, in order to quickly set the lengths of the legs 43 and 45 to required dimensions, marks 51 to 55 as shown in FIGS.
Can be provided. The patterns of the marks 51 to 53 shown in FIG. 5 are obtained by engraving, for example, the dimensions from the outer surface of the wall to the wall receiving hardware. The mark 51 corresponds to the first floor of the house, and the mark 52 corresponds to the second floor of the house. The mark 53 corresponds to the third floor of the house. If the legs 43 shown in FIG. 5 are used, for example, the thumbscrews 48 are tightened in accordance with the mark 51 to detect the horizontality and the verticality on the first floor of the house.
The vertical / horizontal detector 40 is lifted as it is on the building portion of the floor, and the same horizontality and verticality can be detected this time after being aligned with the mark 52. After that, the same vertical / horizontal detector 40 is also held on the third-floor building portion, and the same detection can be performed when the vertical / horizontal detector 40 is aligned with the mark 53. The pattern of the marks 54 and 55 shown in FIG. 6 is obtained by engraving the dimension from the outer wall surface to the beam core, for example, the mark 54 corresponds to the second floor of the house, and the mark 55 corresponds to the third floor of the house. Equivalent to. Such marks 51 to 55 can be formed by forming grooves or by appropriate color coding, and it is also possible to provide scales on the legs 43 and 45 instead of the marks.

In the vertical / horizontal detector 40 of this embodiment having such a structure, three legs 43, 45, and 43 are first attached to the level 41, so that the horizontality and the verticality are measured at three places at a time. In particular, when a long level is used for the level 41, it is possible to detect a sufficiently separated portion. Each leg 43, 45 can slide within the leg base 47, and is fixed by the thumb screw 48. Therefore, by adjusting the thumb screw 48, the legs 43, 4
5 can be set freely, can be applied to various parts of various houses, and one vertical and horizontal detector 40 can be used for the same house flexibly according to various parts. Therefore, construction efficiency can be greatly improved. Further, since the legs 43 and 45 having different lengths can be used at the same time, the vertical / horizontal detector 40 can be sufficiently applied particularly to a steel frame having severe irregularities. In addition, by exchanging the detachable legs, the pattern of the mark can be exchanged, and the construction efficiency can be greatly improved from this point.

The vertical / horizontal detector 10 is provided with a pair of holding frames 12, and the vertical / horizontal detector 40 of this embodiment is provided with three holding frames 42. However, the present invention is not limited to this. The horizontal detector can be equipped with only one or a plurality of holding frames, and the mode of use can be arbitrarily selected according to the shape and situation of the object to be detected.

Referring to FIGS. 7 to 9, a vertical and horizontal detector according to another embodiment of the present invention will be described. The vertical / horizontal detector 60 includes a level 61 capable of detecting whether the detected portion is horizontal, vertical and at an angle of 45 degrees, and a pair of holding portions 62 attached to both ends of the level 61 in the horizontal direction. 6
2 and legs 63, 63 respectively extending from the holding portions 62 in a direction perpendicular to the direction in which the level 61 extends.

The level 61 has three indicators 64, 6
5, 66 are embedded, and it is possible to detect whether the angle is horizontal, vertical, or 45 degrees. The bottom surface 67 of this level 61 is a flat surface as it is as a contact surface of a normal level, and when the pair of legs 63 is removed and used, it can be used in the same manner as a normal level. . The holding portions 62 extend from both ends of the level 61 in a direction in which the extending direction of the level 61 is further extended, and a hole for gripping the leg 63 is provided at a tip side of the holding portion 62. Is provided. The axial direction of this hole is the normal direction of the bottom surface 67 of the level 61, and by fitting the leg 63 into this hole, the leg 63 is extended and fixed in the normal direction. For example, when the holding portion 62 is made of plastic, the leg 63 can be gripped by the elastic force of the plastic.

The leg 63 is a round bar made of metal, wood, plastic, glass, or the like having a uniform diameter, and is simplified without a contact portion in which a magnet is embedded. The leg 63 may be provided with a contact portion in which a magnet is embedded, but the leg 63 can be configured to be lighter in weight than other embodiments because the contact portion is not provided. The leg 63 includes a holding portion 62
It is detachably fitted and attached to the
Can be slid by the holding section 62 to set the legs 63 to different lengths.

FIGS. 8 and 9 show the vertical and horizontal detectors 6 respectively.
FIG. 8 is a perspective view showing the use state of the leg 63 on both sides.
FIG. 9 shows a state in which one leg 63 is retracted. In the use state shown in FIG. 8, the horizontality of the horizontal surface 72 of the member 71 and the horizontality of the horizontal surface 74 of the member 73 are detected. The member 71 has an L-shaped cross section, and a vertically standing portion 79 directly connects the bottom surface of the level 61 to each horizontal surface 72,
Although it is prevented from hitting the level 74, the detection can be performed across the vertical portion 79 by the holding portions 62 and the legs 63 provided at both ends of the level 61, and the construction efficiency is improved. In the use state shown in FIG. 9, one leg 63 is retracted, and only the other leg 63 contacts the detection surface 76 of the member 75. At the same time, the bottom surface 80 of the level 61 is Contact 78. Thus, the detection surface 76 and the vertical surface 78
Constitutes an uneven object to be detected, but the combination of one leg 63 and the bottom surface 80 of the level 61 enables quick detection of horizontality and verticality.

[0032]

As described above, by using the vertical / horizontal detector of the present invention, a convex portion can be formed even on an object having irregularities, such as a steel structure, from the combination of the holding portion and the leg portion. The horizontality and verticality of the detection surface can be detected reliably and with high accuracy by straddling, so that it is not necessary to stretch a water thread or the like, so that the construction efficiency can be greatly improved. Also,
With magnets installed on the legs, it can be attached to materials such as steel members by magnetic force, which promises quick construction work. Furthermore, depending on the combination structure of the holding part and the legs,
By making the legs and the holding portion detachable, the use of the level itself is promoted, and the ordinary level can be used as one element of the vertical and horizontal detector of the present invention. Further, by providing the scales and marks on the legs and the like, the construction work can be performed more quickly.
