Description

  The present invention relates to a jig for measuring the verticality of a building member.

  When constructing a building, it is necessary to remove the collapse and distortion of the member called re-installation before fixing the building member so that it can be installed in a predetermined position without the member falling or twisting. Adjustment work is performed.

  When measuring the verticality of building components that require high building accuracy, a vertical reference line is set using a downward swing that hangs the suspension body with a thread or a laser-type swing, and the vertical reference line and the building It has been generally performed to measure the distance between the member and the vertical measurement surface using a target such as a rectangular scale or a scale.

  In this case, it is necessary to keep the target in contact with the measurement surface with one hand, so that the desired accuracy can be obtained while checking and adjusting the construction status of the unstable building member when the hand is released. The work of fixing was difficult by itself.

  If it is L-shaped like a rectangular scale, it is possible for a single worker to hold the target together with the building member and fix it while checking the installed state, but it is free to hold The degree was low and workability was poor.

  Under such circumstances, various techniques for improving workability have been proposed without requiring an operator to hold a target. For example, Patent Literature 1 and Patent Literature 2 propose a jig using a magnet, and Patent Literature 3 proposes a jig that is attached in a state where a building member is sandwiched using a clamp.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

(First embodiment)
FIG. 1 shows an embodiment of the above-described (1) verticality measuring jig of the present invention. The verticality measuring jig 10 is formed by integrating a clamping means 11 and a verticality measuring ruler 12.

  The sandwiching means 11 has a configuration like a so-called laundry scissors (or futon scissors), and can be attached to the building member so that the building member is sandwiched by the sandwiching portions 11 a and 11 b by the spring force of the spring 13. .

  In the sandwiching means 11 of this example, the sandwiching part 11a that sandwiches the measurement surface (surface to be measured for verticality) side of the building member has a planar shape, and the sandwiching part 11b that sandwiches the opposite surface side facing the measurement surface. Is curved.

  The verticality measuring ruler 12 extends in the vertical direction with respect to the sandwiching portion 11a having a planar shape.

  FIG. 2 is a view showing a state in which the verticality measuring jig 10 of this example is attached to the building member 20.

  As described above, since the sandwiching portion 11a has a planar shape and the sandwiching portion 11b has a curved shape, the sandwiching portion 11a sandwiches the measurement surface 21 of the building member 20 in a surface contact state as shown in FIG. Then, the state in which the clamping unit 11b clamps the facing surface 22 facing the measurement surface 21 in a point contact state or in a line contact state in a direction perpendicular to the expanded surface of the clamping means 11 (ie, a surface parallel to the paper surface) is stable. It is the attached state.

  Therefore, the vertical measuring ruler 12 can be easily and reliably perpendicular to the measurement surface 21 in response to a change in the interval between the surfaces sandwiched by the sandwiching means 11 (the thickness of the building member 20 in the sandwiched portion). Since it can attach to the building member 20, the perpendicularity of the building member can be measured with high accuracy.

  The “point contact” or “line contact” as used in the present invention is not limited to the point contact or line contact state, but rather than the contact area between the planar holding part 11 a and the measurement surface 21. The surface contact state in a sufficiently small area is included.

  In this example, the sandwiching portion 11b is formed in a curved shape. However, the means is not particularly limited as long as the above contact state can be realized. For example, a projecting portion having a relatively small area may be formed on the sandwiching portion 11b. The area of the clamping part 11b may be formed smaller than the area of the clamping part 11a.

(Second Embodiment)
FIG. 3 shows an embodiment of the above-described (2) verticality measuring jig according to the present invention. The verticality measuring jig 30 is formed by integrating a clamping means 31 and a verticality measuring ruler 32.

  The clamping means 31 is configured like a so-called laundry scissors (or futon scissors), like the clamping means 11, and the building members are clamped by the clamping portions 31 a and 31 b by the spring force of the spring 33. Can be attached.

  As shown in the perspective view of FIG. 4, the verticality measuring ruler 32 is in contact with the contact surface portion 32 a that is in contact with the measurement surface of the building member (surface to be measured for verticality), and the contact surface portion 32 a. And a ruler portion 32b extending in the vertical direction.

  Further, the verticality measuring ruler 32 is attached to the clamping means 31 by a pin 33 so as to be rotatable within the expanded surface of the clamping means 31 (that is, within the plane of the paper surface of FIG. 3).

  FIG. 5 is a view showing a state in which the verticality measuring jig 30 of this example is attached to the building member 50.

  As described above, the verticality measuring ruler 32 is attached to the clamping means 31 so as to be rotatable within the expanded surface of the clamping means 31 by the pins 33, so that it comes into contact with the measurement surface 51 of the building member 50. As shown in FIG. 5, the clamping means 31 can be attached with the contact surface portion 32 a in contact with the measurement surface 51 of the building member 50.

  Accordingly, the building member is adapted to easily and reliably be perpendicular to the measuring surface 51 in correspondence with the change in the interval between the surfaces sandwiched by the sandwiching means 31 (the thickness of the building member 50 in the sandwiched portion). Since it can attach to 50, the perpendicularity of a building member can be measured accurately.

(Third embodiment)
FIG. 6 is an explanatory view of an embodiment of the verticality measuring jig according to the present invention (3), and shows a state in which the verticality measuring jig 60 is attached to the building member 70. The verticality measuring jig 60 is formed by integrating a clamping means 61, a first verticality measuring ruler 62, and a second verticality measuring ruler 63.

  The sandwiching means 61 has a configuration like a so-called laundry scissors (or futon scissors) similar to the sandwiching means 11, and the building member is sandwiched between the sandwiching portions 61 a and 61 b by the spring force of the spring 64. Can be attached.

  Further, in the clamping means 61, like the clamping means 11, the clamping part 61 a that clamps the building member 70 on the first measurement surface 71 side has a planar shape, and faces the first measurement surface 71. The clamping part 61b that clamps has a curved surface shape.

  The first verticality measuring ruler 62 extends in the vertical direction with respect to the clamping portion 61a having a planar shape.

  The second verticality measuring ruler 63 includes a contact surface portion 63a that is in contact with a second measurement surface 73 that is continuous with the first measurement surface 71 and the opposed surface 72, and a direction perpendicular to the contact surface portion 63a. And an extended ruler portion 63b.

  The second verticality measuring ruler 63 is attached to the clamping means 61 by a pin 65 so as to be rotatable within the expanded surface of the clamping means 61.

  As described above, the verticality measuring jig 60 of this example has the functions of both the verticality measuring jigs 10 and 30 of the first and second exemplary embodiments, and is simple and reliable. The first perpendicularity measurement ruler 62 is perpendicular to the first measurement surface 71, and the ruler part 63 b of the second perpendicularity measurement ruler 63 is perpendicular to the second measurement surface 73. So that it can be attached to building components.

  For this reason, by using the jig 60 for measuring the verticality of this example, the verticality of the two measurement surfaces of the building member can be measured with a single attachment, and the working efficiency can be improved. Moreover, since attachment to a building member is possible in two directions, the attachment direction can be appropriately selected according to the situation at the site, and versatility is high.

  After attaching the jig for measuring the verticality of the present invention to the building member as shown in FIGS. 2, 5 and 6, as in the conventional method, the hanging swing of the hanging body hanging with a thread or the laser swinging down is applied. Set the vertical reference line, or, if the building material is a pillar, etc., measure the verticality by marking the floor on the floor at a certain distance from the measurement surface and using a surveying machine such as transit can do.

  In addition, the jig | tool for a perpendicularity measurement of this invention is applicable not only to vertical members, such as a pillar, a stud, and a wall material, but to all building members which have a vertical surface.
