Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the invention described in Patent Document 1 above, when installing the concrete plate, it is necessary to secure a space in advance for arranging the eye plate between the end faces of the concrete plate. At this time, if this space is too large, it is conceivable that the gap between the concrete and the eye plate will become large. On the other hand, if this space is too small, it will be difficult to arrange the eye plate between the end faces of the concrete plate, and it will be necessary to adjust the position of the concrete plate.

[0005] In consideration of the above facts, an object of the present invention is to obtain a jig for arranging an eye plate that can appropriately secure a space in which the eye plate can be arranged between floor slabs.

Means for Solving the Problems

[0006] The jig for positioning joint plates in a building according to the first embodiment comprises a plurality of positioning shafts that can be inserted into a plurality of insertion holes formed in the upper flange portion of a floor beam extending in a first direction, and a jig body portion that, when positioned relative to the floor beam via the positioning shafts, has a dimension in a second direction perpendicular to the first direction when viewed from the building height direction that is greater than or equal to the length in the second direction of a concrete joint plate positioned between a pair of concrete floor slabs that constitute a part of the floor portion and are arranged in a continuous manner in the second direction, and less than or equal to the distance in the second direction between the floor slabs.

[0007] The jig for arranging joint boards in a building according to the first embodiment comprises a positioning shaft and a jig body. The positioning shaft is inserted into a plurality of through holes formed in the upper flange portion of a floor beam extending in a first direction, thereby positioning the jig body relative to the floor beam.

[0008] Furthermore, when the jig body is positioned relative to the floor beam, the dimension in the second direction, perpendicular to the first direction when viewed from the building height direction, is set to be greater than or equal to the length in the second direction of the concrete joint plate placed between a pair of concrete floor slabs that constitute a part of the floor and are arranged in a continuous line in the second direction, and less than or equal to the distance in the second direction between the floor slabs.

[0009] Therefore, when the jig body is positioned relative to the floor beam, if one of the pair of floorboards arranged in a second direction is pressed against the jig body from one side in the second direction, and the other is pressed against the jig body from the other side in the second direction, and then the jig body is removed from between the floorboards, the same spacing as the above dimension is secured between the floorboards.

[0010] As a result, in this embodiment, a joint board can be placed between a pair of floorboards arranged in a second direction without interfering with the floorboards.

[0011] The jig for arranging joint plates according to the second embodiment is provided in the jig for arranging joint plates according to the first embodiment, wherein the side surface of the jig body is provided with a reference groove that extends along a straight line that passes through the center of the upper flange portion in the second direction and extends in the building height direction when viewed from the first direction, when the jig body is positioned with respect to the floor beam.

[0012] In the jig for arranging joint plates according to the second embodiment, a reference groove is provided on the side surface of the jig body, and this reference groove extends along a straight line that passes through the center of the upper flange in the second direction and extends in the building height direction when the jig body is positioned relative to the floor beam, as viewed from the first direction.

[0013] Therefore, in this embodiment, the worker can confirm the position of the center of the floor beam in the second direction, i.e., the beam center, based on the reference groove.

[0014] The jig for arranging joint plates according to the third embodiment further comprises a main body support portion interposed between the jig body portion and the floor beam when the jig body portion is positioned relative to the floor beam, and the bottom surface of the main body support portion is provided with a marking groove portion that extends along a center line passing through the center of the upper flange portion in the second direction when viewed from the building height direction.

[0015] In the jig for positioning joint boards according to the third embodiment, a main support portion is interposed between the jig body and the floor beam when the jig body is positioned relative to the floor beam. A marking groove is provided on the bottom surface of this main support portion, and when the jig body is positioned relative to the floor beam, this marking groove extends along a center line passing through the center of the upper flange portion in the second direction when viewed from the building height direction.

[0016] Therefore, in this embodiment, for example, a string used for marking can be secured to the marking groove, and this string can be positioned along the second center of the floor beam, i.e., the beam core.

[0017] The jig for positioning the floor beam according to the fourth embodiment is a jig for positioning the floor beam according to any one of the first to third embodiments, wherein the jig body is positioned such that the first direction is the longitudinal direction by inserting the positioning shaft into a plurality of insertion holes, which are arranged at predetermined intervals on one side in the second direction relative to the first centerline of the upper flange portion that extends in the first direction when viewed from the building height direction, or a plurality of insertion holes, which are arranged at predetermined intervals on the other side in the second direction relative to the first centerline of the upper flange portion that extends in the first direction, or a plurality of insertion holes, which are arranged at predetermined intervals on the other side in the second direction relative to the first centerline of the upper flange portion that extends in the second direction, and are arranged in the first direction. Furthermore, in a state in which the jig body is positioned with respect to the first insertion hole or the second insertion hole, the jig comprises a first reference surface portion perpendicular to the second direction, and a second reference surface portion arranged parallel to the first reference surface portion and spaced at the same interval as the reference dimension set to be greater than or equal to the length of the reference weld plate in the second direction and less than or equal to the distance in the second direction between the floorboards, and in a first state in which the first reference surface portion is on the web portion side, it is possible to arrange it so as to be symmetrical with respect to a second center line passing through the center of the first extension portion or the center of the second extension portion when viewed from the first direction, and in a second state in which the second reference surface portion is on the web portion side, it is possible to arrange it so as to be aligned with the first center line when viewed from the building height direction.

[0018] In the fourth embodiment of the jig for positioning the eye plate, the jig body is positioned relative to a first or second insertion hole provided in the upper flange portion.

[0019] More specifically, the first insertion holes are arranged in a plurality at predetermined intervals in the first direction relative to the first centerline extending in the first direction of the upper flange portion, on the first extension portion on one side of the second direction from the web portion of the floor beam in the upper flange portion when viewed from the building height direction.

[0020] On the other hand, the second insertion hole portions are arranged in a plurality at a predetermined interval on the other side in the second direction with respect to the first center line when viewed in the building height direction on the second extending portion on the other side in the second direction of the web portion of the floor beam in the upper flange portion and are continuous in the first direction.

[0021] And the jig main body portion can be positioned with the first direction as the longitudinal direction by inserting the positioning shaft portion into the first insertion hole portion or the second insertion hole portion.

[0022] In addition, the jig main body portion includes a first reference surface portion and a second reference surface portion. Specifically, the first reference surface portion is orthogonal to the second direction in a state where the jig main body portion is positioned with respect to the first insertion hole portion or the second insertion hole portion.

[0023] On the other hand, the second reference surface portion is arranged in parallel with the first reference surface portion and is arranged at the same interval as the reference dimension set to be not less than the length in the second direction of the reference template and not more than the distance in the second direction between the floor boards with respect to the first reference surface portion.

[0024] And in the first state where the first reference surface portion of the jig main body portion faces the web portion side, the jig main body portion is arranged to be symmetric with respect to the second center line passing through the center of the first extending portion or the center of the second extending portion when viewed in the first direction.

[0025] Therefore, in a state where the jig main body portion is positioned with respect to the floor beam, when one of the pair of floor boards arranged continuously in the second direction is pressed against the jig main body portion from one side in the second direction and the other is pressed against the jig main body portion from the other side in the second direction, and then the jig main body portion is removed from between the floor boards, a distance the same as the reference dimension is secured between the floor boards so as to be symmetric with respect to the second center line when viewed in the first direction.

[0026] As a result, in this aspect, the reference template can be arranged so as to be positioned above the center of the first extending portion or the center of the second extending portion when viewed in the first direction between the pair of floor boards arranged continuously in the second direction.

[0027] On the other hand, in the second state where the second reference surface portion of the jig main body portion faces the web portion side, the jig main body portion is arranged such that the second reference surface portion is along the first center line of the upper flange portion when viewed from the building height direction.

[0028] Therefore, in this aspect, in the second state, the two jig main body portions can be positioned with respect to the first insertion hole portion and the second insertion hole portion respectively, and these jig main body portions can be arranged adjacent to each other in the second direction.

[0029] As a result, when one of a pair of floor boards arranged continuously in the second direction is pressed against the first reference surface portion of one jig main body portion from one side in the second direction and the other is pressed against the first reference surface portion of the other jig main body portion from the other side in the second direction, and then these jig main body portions are removed from between the floor boards, a space of about twice the reference dimension is secured between the floor boards so as to be symmetric with respect to the first center line when viewed from the building height direction.

[0030] Therefore, in this aspect, a template having a length in the second direction set to about twice the length of the reference template can be arranged between a pair of floor boards arranged continuously in the second direction so as to be located on the first center line when viewed from the building height direction.

Advantages of the Invention

[0031] As described above, the template arrangement jig according to the first aspect has an excellent effect that an appropriate space for arranging the template between the floor boards can be secured.

[0032] The template arrangement jig according to the second aspect has an excellent effect that the efficiency of operations such as chipping work on the upper surface of the floor beam can be improved. [[ID=​​​​​​The jig for arranging grout plates according to the fourth embodiment has the excellent effect of being able to appropriately secure the spacing between floorboards so that grout plates can be arranged, depending on the shape of the grout plates.

[Modes for carrying out the invention]

[0036] Hereinafter, an example of an embodiment of the jig for arranging joint boards according to the present invention will be described using Figures 1 to 11. First, the configuration of a "building 12" equipped with a "floor section 10" constructed using the jig for arranging joint boards according to this embodiment will be described.

[0037] As shown in Figure 11, the building 12 is constructed using a steel frame construction method and is configured as a multi-story dwelling, including a lower floor (not shown) and an upper floor 14.

[0038] The structural frame 16 of this building 12 is composed of multiple columns 18, multiple beams 20, and multiple beams 22. Specifically, the columns 18 are erected at predetermined intervals on a foundation (not shown) and constitute the lower floor portion of the structural frame 16.

[0039] More specifically, the column 18 is composed of a rectangular cylindrical main body extending in the vertical direction of the building, and a base plate which is rectangular in shape when viewed from above and is joined to the upper and lower ends of the main body by welding or other joining means.

[0040] Beam 20 spans the upper ends of columns 18 and is supported from below the building at these upper ends. Beam 22 is connected to beam 20 via connecting members (not shown) and extends in a direction perpendicular to beam 20 when viewed from the building height direction.

[0041] Furthermore, beams 20 and 22 are positioned at the boundary between the lower floor and the upper floor 14, functioning as ceiling beams in the lower floor of the building 12 and as floor beams in the upper floor 14.

[0042] In the following, the longitudinal direction of beam 20 will be referred to as the X direction, the longitudinal direction of beam 22 as the Y direction, and the building height direction as the Z direction. In each figure, the X direction is indicated by arrow X, the Y direction by arrow Y, and the Z direction by arrow Z.

[0043] More specifically, as shown in Figure 9, the beam 20 is made of I-shaped steel and includes an "upper flange portion 20A" which constitutes the upper side of the building, a lower flange portion (not shown) which constitutes the lower side of the building, and a "web portion 20B" which connects the upper flange portion 20A and the lower flange portion in the building height direction.

[0044] As shown in Figure 8, the "extension portion 20A1," which is the first extension portion on one side in the Y direction from the web portion 20B of the upper flange portion 20A, has multiple "insertion holes 24," which are first insertion holes, arranged in a line in the X direction with a spacing P1 (for example, 28 mm) on one side in the Y direction relative to the "center line CL1," which is the first center line extending in the X direction of the upper flange portion 20A when viewed from the Z direction. The center line CL1 can also be considered as the beam center of the beam 20.

[0045] For example, the distance between one end of the extension portion 20A1 in the Y direction and the center line CL1 is set to 50 mm, and the thickness of the web portion 20B is set to 4 mm. In other words, when viewed from the Z direction, the center of the extension portion 20A1 in the Y direction is located 2 mm toward the center line CL1 relative to the center of the through hole portion 24.

[0046] Furthermore, among the multiple through-holes 24, in the four through-holes 24 where the "seat plate placement jig 26 (hereinafter referred to as jig 26)" is positioned as described later, the distance P2 between the through-hole 24 located furthest to one or the other side in the X direction and the adjacent through-hole 24 is set to 52 mm as an example. Also, the distance P3 between the two through-holes 24 located towards the center in the X direction among the above four through-holes 24 is set to 56 mm as an example.

[0047] On the other hand, in the upper flange portion 20A, the "extension portion 20A2," which is a second extension portion on the other side in the Y direction from the web portion 20B, has multiple "through holes 28," which are second through holes, arranged in a line in the X direction with a spacing P1 between them on the other side in the Y direction relative to the center line CL1 when viewed from the Z direction. The diameter of the through holes 28 is set to be the same length as the diameter of the through holes 24.

[0048] For example, the distance between the other end of the extension portion 20A2 in the Y direction and the center line CL1 is set to 50 mm. In other words, when viewed from the Z direction, the center of the extension portion 20A2 in the Y direction is located 2 mm toward the center line CL1 relative to the center of the insertion hole portion 28.

[0049] Furthermore, among the multiple through-holes 28, in the four through-holes 28 where the jig 26 is positioned as described later, the distance between the through-hole 28 located furthest to one or the other side in the X direction and the adjacent through-hole 28 is set to distance P2. Also, the distance between the two through-holes 28 located towards the center in the X direction among the four through-holes 28 is set to distance P3. Note that the through-holes 24 and 28 are arranged so that, when viewed from the Y direction, the centers of the through-holes 24 and 28 overlap.

[0050] Furthermore, the web portion 20B is provided with a circular through-hole 30 for pipe installation, as shown in Figure 5. The center of this through-hole 30 is located on the perpendicular bisector of the line segment connecting the centers of two of the four through-holes 24 (through-holes 28) that are located towards the center in the X direction when viewed from the Y direction.

[0051] On the other hand, as shown in Figure 10, beam 22 has the same configuration as beam 20, including an "upper flange portion 22A", a lower flange portion (not shown), and a "web portion 22B".

[0052] As also shown in Figure 2, the "extension portion 22A1," which is the first extension portion of the upper flange portion 22A located on one side in the X direction from the web portion 22B, is provided with a through hole portion 24, similar to the extension portion 20A1. On the other hand, the "extension portion 22A2," which is the second extension portion of the upper flange portion 22A located on the other side in the X direction from the web portion 22B, is provided with a through hole portion 28, similar to the extension portion 20A2. The web portion 22B is also provided with a through portion 30, similar to the web portion 20B.

[0053] Returning to Figure 11, a "floor slab 32" and a "joint plate 34" (which serve as a reference joint plate) made of lightweight aerated concrete, which constitute part of the floor 10, are placed on the upper flange portion 20A of the beam 20. On the other hand, a "floor slab 36" and a "joint plate 38" made of lightweight aerated concrete, which also constitute part of the floor 10, are placed on the upper flange portion 22A of the beam 22. In this embodiment, as an example, the thickness of the lightweight aerated concrete slabs that make up floor slab 32, joint plate 34, floor slab 36, and joint plate 38 is set to 60 mm.

[0054] As shown in Figure 9, the floor slab 32 is a rectangular plate with its longitudinal direction as the Y direction when viewed from the Z direction, and it spans between adjacent beams 20 in the Y direction. One end of the floor slab 32 in the Y direction is supported by an extension 20A2, and the other end in the Y direction is supported by an extension 20A1.

[0055] On the other hand, the floorboard 36 is a rectangular plate with its longitudinal direction as the X direction when viewed from the Z direction, and it spans between adjacent beams 22 in the X direction. The distance D1 in the Y direction between floorboard 36 and floorboard 32 located near beam 20 is set to 60 mm as an example, as shown in Figure 1. A joint board 34 is placed between floorboard 36 and floorboard 32 located near beam 20.

[0056] The joint plate 34 is shaped like a rectangular parallelepiped and is positioned with its longitudinal direction as the X direction. The width WM1 (length in the Y direction when installed) of this joint plate 34 is set to 55 mm as an example.

[0057] On the other hand, the floorboards 32 are arranged in a continuous line in the X direction between adjacent columns 18 in the X direction. Also, as shown in Figures 2 and 10, the distance D2 in the X direction between floorboards 32 located near beams 22 is set to 120 mm as an example. And, between floorboards 32 located near beams 22, joint boards 38 are placed.

[0058] The grout plate 38 is a rectangular plate when viewed from the Z direction, and is positioned with its long side as the Y direction. The width WM2 of this grout plate 38 (length in the X direction when installed) is set to 115 mm as an example.

[0059] In this embodiment, when installing floorboards 32, fascia board 34, floorboards 36, and fascia board 38, the jig 26 is used to ensure the distance D1 between floorboard 36 and floorboard 32 and the distance D2 between floorboards 32. The configuration of the jig 26 will be described in detail below.

[0060] As shown in Figures 3 and 4, the jig 26 comprises a "jig body portion 40", a "body support portion 42", a plurality of connecting shaft portions 44, a plurality of "positioning shaft portions 46", and a handle portion 47.

[0061] More specifically, the jig body 40 is rectangular in shape and, as an example, is made of an extruded aluminum alloy. This jig body 40 comprises an upper wall portion 40A that constitutes its upper part, a lower wall portion 40B that constitutes its lower part, and a "side wall portion 40C" as a first reference surface portion and a "side wall portion 40D" as a second reference surface portion that connect these.

[0062] In the following, the width WJ1 of the jig body 40 is set to 60 mm (distance D1) as an example, the height HJ1 is set to 80 mm as an example, and the depth (length in the longitudinal direction) LJ1 is set to 250 mm as an example. Furthermore, in the following, the width direction of the jig 26 will be referred to as the W direction, the height direction of the jig 26 as the H direction, the depth direction of the jig 26 as the L direction, and the width WJ1 will be referred to as the standard dimension. In Figures 3, 4, and 6, the W direction is indicated by arrow W, the H direction is indicated by arrow H, and the L direction is indicated by arrow L.

[0063] Furthermore, the side wall portions 40C and 40D are provided with a "reference groove portion 48" that, when viewed from the W direction, passes through the center in the L direction and extends in the H direction.

[0064] The main support portion 42 is rectangular in shape and, for example, is made of an extruded aluminum alloy. The jig body portion 40 comprises an upper wall portion 42A that forms its upper part, a lower wall portion 42B that forms its lower part, and side wall portions 42C and 42D that connect them. The main support portion 42 is positioned below the jig body portion 40 in the H direction, with its longitudinal direction being the L direction and the side wall portion 42C facing the side wall portion 40C side. The upper wall portion 42A is attached to the lower wall portion 40B of the jig body portion 40 by a mounting member (not shown), thereby fixing it to the jig body portion 40.

[0065] For example, the width WJ2 of the main support portion 42 is set to 50 mm, the height HJ2 is set to 25 mm, and the depth (length in the longitudinal direction) LJ2 is set to 250 mm. Furthermore, for example, the main support portion 42 is positioned relative to the jig body portion 40 such that the side wall portion 42C is recessed 4 mm towards the center in the W direction relative to the side wall portion 40C of the jig body portion 40, and the end face in the L direction coincides with the end face of the jig body portion 40.

[0066] Furthermore, the side walls 42C and 42D are provided with a reference groove 50 that, when viewed from the W direction, passes through the center in the L direction and extends in the H direction. The reference groove 50 is located on the same line as the reference groove 48 when viewed from the W direction.

[0067] On the other hand, the lower wall portion 42B is provided with four through-holes 52 spaced at predetermined intervals in the L direction, and a positioning shaft portion 46 is inserted through each of these through-holes 52, as will be described later.

[0068] Furthermore, as shown in Figure 6, a "marking groove 54" is provided on the "bottom surface 42B1" of the lower wall portion 42B. This marking groove 54 passes through the center of the bottom surface 42B1 in the L direction when viewed from the H direction and extends in the W direction, and is formed in a V-shape that narrows as it moves from the lower side in the H direction to the upper side in the H direction when viewed from the W direction.

[0069] Four connecting shaft portions 44 are arranged on the lower surface of the upper wall portion 42A of the main body support portion 42 at predetermined intervals in the L direction. Specifically, the connecting shaft portion 44 is cylindrical in shape, extending downward in the H direction from the upper wall portion 42A, and a male threaded portion 44A is provided on its outer circumferential surface. The tip of the connecting shaft portion 44 is located on the upper side in the H direction of the lower wall portion 42B.

[0070] Furthermore, the four connecting shaft portions 44 are arranged symmetrically with respect to the center of the main support portion 42 when viewed from the W direction, and the distance between the center of the connecting shaft portion 44 located furthest to one or the other side in the L direction and the center of the adjacent connecting shaft portion 44 is set to distance P2. On the other hand, the distance between the centers of the two connecting shaft portions 44 located towards the center in the L direction is set to distance P3.

[0071] Furthermore, the positions of the four connecting shaft portions 44 in the W direction are set such that the center of each connecting shaft portion 44 is located on the side wall portion 42D side, with the same spacing P1 as the surface of the side wall portion 42C. Each of these connecting shaft portions 44 is fitted with a positioning shaft portion 46.

[0072] The positioning shaft portion 46 is cylindrical or cylindrical in shape so as to be inserted into or fitted into the insertion holes 24 and 28, and has a female thread portion (not shown) on its inside that can engage with the male thread portion 44A. The positioning shaft portion 46 is attached to the connecting shaft portion 44 with its female thread portion engaged with the male thread portion 44A, extending a predetermined length downward in the H direction from the lower wall portion 42B.

[0073] On the other hand, the handle portion 47 is, for example, made by bending a steel plate, and is U-shaped, widening from the upper side in the H direction to the lower side in the H direction when viewed from the W direction. This handle portion 47 is attached to the jig body portion 40 by a mounting member (not shown).

[0074] The jig 26 configured as described above can be positioned relative to the beam 20 (beam 22) such that the longitudinal direction of the beam 20 (beam 22) is in the L direction by inserting or fitting the positioning shaft portion 46 into the four insertion holes 24 (insertion holes 28) described above.

[0075] More specifically, as shown in Figure 1, the jig 26 can be positioned such that, in the first state where the side wall portion 40C is on the web portion 20B side of the beam 20, the jig body portion 40 is symmetrical with respect to the "center line CL2", which is a second center line passing through the center of the extension portion 20A1 when viewed from the X direction.

[0076] Furthermore, as shown in Figure 2, the jig 26 can be positioned such that, in the second state where the side wall portion 40D is on the web portion 22B side of the beam 22, the surface of the side wall portion 40D of the jig body portion 40 is aligned with the center line CL1 when viewed from the Z direction.

[0077] <Operation and Effects of This Embodiment> Next, the operation and effects of this embodiment will be described.

[0078] In this embodiment, as shown in Figure 1, the jig 26 comprises a positioning shaft portion 46 and a jig body portion 40. For example, the positioning shaft portion 46 is inserted into multiple insertion holes 24 formed in the upper flange portion 20A of the beam 20 extending in the X direction, thereby positioning the jig body portion 40 relative to the beam 20.

[0079] Furthermore, when the jig body 40 is positioned relative to the beam 20, as shown in Figures 3 and 9, the dimension in the Y direction (width WJ1) perpendicular to the X direction when viewed from the Z direction is set to be greater than or equal to the Y-direction length (width WM1) of the concrete joint plate 34 that is placed between the concrete floor plates 32 and 36, which constitute a part of the floor 10 and are arranged in a continuous line in the Y direction, and less than or equal to the Y-direction distance D1 between the floor plates 32 and 36.

[0080] Therefore, when the jig body 40 is positioned relative to the beam 20, if floor plate 36 is pressed against the jig body 40 from one side in the Y direction and floor plate 32 is pressed against the jig body 40 from the other side in the Y direction, and then the jig body 40 is removed from between floor plate 32 and floor plate 36, a gap equal to the width WJ1 is secured between floor plate 32 and floor plate 36.

[0081] As a result, in this embodiment, the joint plate 34 can be placed between floorboards 32 and 36 that are arranged in a continuous line in the Y direction without interfering with floorboards 32 and 36. Therefore, according to the jig 26 of this embodiment, an appropriate spacing can be secured between floorboards to allow for the placement of joint plates.

[0082] Furthermore, in this embodiment, as shown in Figure 4, reference grooves 48 are provided on the side walls 40C and 40D of the jig body 40. These reference grooves 48 extend along a straight line that passes through the center of the upper flange portion 20A in the Y direction and extends in the Z direction when viewed from the X direction, in a state where the jig body 40 is positioned relative to the beam 20 by inserting a pair of positioning shafts 46 located on the center side in the L direction into insertion holes 24 and 28 adjacent to each other in the Y direction of the beam 20.

[0083] Therefore, in this embodiment, the worker can confirm the position of the beam center of the beam 20 based on the reference groove 48. As a result, the jig 26 according to this embodiment can improve the efficiency of marking work on the upper surface of the floor beam.

[0084] Furthermore, in this embodiment, as also shown in Figure 6, when the jig body 40 is positioned relative to the beam 20 such that its longitudinal direction is the Y direction, a body support portion 42 is interposed between the jig body 40 and the beam 20. A marking groove portion 54 is provided in the 42B1 of this body support portion 42, and this marking groove portion 54 extends along the center line CL1 that passes through the center of the upper flange portion in the Y direction when viewed from the Z direction, when the jig body 40 is positioned relative to the beam 20.

[0085] Therefore, in this embodiment, for example, as shown in Figure 7, a string 56 used for marking can be secured in the marking groove 54, the string 56 can be positioned along the beam center of the beam 20, and the position of the beam center of the beam 20 can be indicated on the surface of the beam 20 with ink or chalk attached to the string 56. Thus, the jig 26 according to this embodiment can improve the efficiency of marking work on the upper surface of the floor beam.

[0086] Furthermore, in this embodiment, as shown in Figure 1, for example, when the jig body portion 40 is positioned in the beam 20 in a first state where the side wall portion 40C is on the web portion 20B side, the jig body portion 40 is positioned symmetrically with respect to the center line CL2 passing through the center of the extension portion 20A1 when viewed from the X direction.

[0087] Therefore, when the jig body 40 is positioned relative to the beam 20, if floor plate 36 is pressed against the jig body 40 from one side in the Y direction and floor plate 32 is pressed against the jig body 40 from the other side in the Y direction, and then the jig body 40 is removed from between floor plate 32 and floor plate 36, the same distance as the standard dimension is secured between floor plate 32 and floor plate 36 so as to be symmetrical with respect to the center line CL2 when viewed from the X direction.

[0088] As a result, in this embodiment, the cover plate 34 can be positioned between a pair of floorboards 32 and 36 arranged in a continuous line in the Y direction, such that it is located on the center of the extension portion 20A1 when viewed from the X direction.

[0089] On the other hand, as shown in Figure 2, for example, when the jig body 40 is positioned in the beam 22 in a second state where the side wall portion 40D of the jig body 40 is on the web portion 22B side, the jig body is positioned such that, when viewed from the Z direction, the side wall portion 40D is aligned with the center line CL1 of the upper flange portion 22A.

[0090] Therefore, in this embodiment, in the second state of the jig 26, the two jig body portions 40 can be positioned relative to the insertion hole portion 24 and the insertion hole portion 28, respectively, and these jig body portions 40 can be arranged adjacent to each other in the X direction.

[0091] As a result, when the two jig bodies 40 are positioned adjacent to the floor beam 22, and one of the pair of floorboards 32 arranged in a continuous line in the X direction is pressed against the side wall 40C of one jig body 40 from one side in the X direction, and the other is pressed against the side wall 40C of the other jig body 40 from the other side in the X direction, and then these jig bodies 40 are removed from between the floorboards 32, a gap of about twice the standard dimension is secured between the floorboards 32 so as to be symmetrical with respect to the center line CL1 when viewed from the Z direction.

[0092] Therefore, in this embodiment, a joint plate 38, whose width WM2 is set to approximately twice the width WM1 of the joint plate 34, can be placed between a pair of floorboards 32 arranged in a continuous line in the X direction, such that it is located on the center line CL1 when viewed from the Z direction. In this way, in this embodiment, an appropriate spacing can be secured between floorboards to accommodate joint plates, depending on the shape of the joint plate.

[0093] Furthermore, in this embodiment, as shown in Figure 3, the position of the connecting shaft portion 44 in the W direction is set such that the center of the connecting shaft portion 44 is located on the side wall portion 42D side with respect to the surface of the side wall portion 42C, at the same distance P1 as the distance P1.

[0094] Therefore, as shown in Figure 1, when the jig 26 is positioned relative to the beam 20 such that the jig body 40 is in the first state, the side wall portion 42C is positioned along the beam center of the beam 20 when viewed from the Z direction. As a result, in this embodiment, the worker can confirm the position of the beam center of the beam 20 based on the side wall portion 42C.

[0095] <Supplementary explanation of the above embodiment> (1) In the above-described embodiment, the jig 26 was provided with a main body support portion 42, but depending on the specifications of the beam, the jig 26 may be configured without a main body support portion 42 in order to simplify the configuration of the jig 26.

[0096] (2) In the above-described embodiment, the reference groove portion 48 was provided in the side wall portion 40C and the side wall portion 40D of the jig body portion 40, but depending on the specifications of the beam, a wall portion may be provided at the end of the jig body portion 40 and the reference groove portion may be provided in the wall portion.
