Description

  The present invention relates to a heat insulating material made of a synthetic resin foam inserted into a frame constituting a floor, ceiling, or roof portion in a house made of a wooden frame structure, and a heat insulating structure using the heat insulating material.

  A wooden frame structure commonly known as a two-by-four structure is known, and many houses are built in Japan using a wooden frame structure. In a wooden frame structure, a frame itself formed by square members functions as a structural member. In Japan, a square member of 38 mm × 89 mm is generally used as a base material for the frame. Further, as in the case of a house with a frame structure, in a wooden frame structure, heat insulation work is performed in which a heat insulating material made of a synthetic resin foam is inserted into the floor portion, the roof portion, or the ceiling portion. The standard structural material arrangement module of the frame material in the wooden frame structure is 455 mm, and the horizontal width of the heat insulating material inserted between the vertical frame materials is generally 455 mm−38 mm = 417 mm.

  However, in floor construction, ceiling construction, and roof construction, module collapse occurs at the place where the wall is engaged. A vertical frame material corresponding to floor joist, field edge material, and hanging wood with a width of 38 mm is placed on the outside of the wall where the wall frame width is 89 mm, but the measurement reference line of the placement module is at the center of the wall Since it is set, the module line at the place where the wall is engaged and the center line of the vertical frame material corresponding to the floor joist material, the field material, and the hanging lumber are shifted outward by 25.5 mm. Accordingly, the dimension between the structural materials (the width for filling the heat insulating material) is increased.

  Furthermore, in a wooden frame structure, in a vertical frame material equivalent to floor joist, field material, and hanging lumber, two square members, which are the same base material, should be used in layers where structural reinforcement is required. There are many. In this case, the width of the structural material is 38 × 2 = 76 mm, and the dimension between the structural materials (the width for filling the heat insulating material) is reduced accordingly.

  Patent Document 1 discloses a side edge of a heat insulating material so that heat insulation can be easily performed using a heat insulating material having a standard width even if the inner dimensions of the structural material dimensions (between vertical frame materials) change. Two slits are formed in the width direction at a position that is half the width between the vertical frame members in the width direction and the width portion, and a part of the heat insulating material is separated using the slits, so that the remaining partial heat insulating material Describes a heat insulating material for a wooden frame structure that can be easily inserted into different internal dimensions between vertical frame members.

  Patent Document 2 discloses a structure in which a V-shaped split groove is formed along the side edge of a rectangular synthetic resin foam heat insulating material, and the front side width dimension of the heat insulating material is to be inserted. There is described a heat insulating material for building which is set narrower than the interval between members and whose width on the rear side is set wider than the interval between structural members to be inserted. This heat insulating material can be easily inserted between adjacent structural members due to the difference in dimensions between the front surface and the rear surface, and the V-shaped dividing groove gradually becomes narrower in the process of further pressing, so that the heat insulating material The material is in a state of being firmly fitted between the structural members.

Japanese Patent Laid-Open No. 7-217051 JP-A-10-110483

  The heat insulating material for the wooden frame structure described in Patent Document 1 is a place where the internal dimensions between the vertical frame materials are different by adjusting the partial heat insulating material, which is partially separated using a slit, at the construction site. There is an advantage that it can be easily inserted. However, the lateral width of the heat insulating material described in Patent Document 1 is a little wider than the inner dimension between the vertical frame members to be inserted, and it cannot be said that the inserting operation is easy. In addition, in a wooden frame structure, generally, a square member having a dimension of 38 mm × 89 mm is used as a vertical frame member and a horizontal frame member. Therefore, as described above, in floor construction, ceiling construction, and roof construction, Module breakage occurs at the joint location, and the module line and the center line of the vertical frame material corresponding to the floor joist material, the field material, and the hanging lumber are 25.5 mm, that is, from the standard part 417 mm between the vertical frame materials However, in the heat insulating material described in Patent Document 1, this point is not taken into consideration, although it is 442.5 mm wide by 25.5 mm [= (417+ (89−38) / 2) mm].

  On the other hand, in the heat insulating material described in Patent Document 2, the width dimension on the front side is set narrower than the interval between the structural members to be inserted, and the width dimension on the rear side is set wider than the interval between the structural members to be inserted. As a result, the insertion between the adjacent structural members is easy, and after that, the insulating material is firmly pressed between the structural members by further pushing. However, there is no suggestion of a technique of removing a part to form a partial heat insulating material for insertion between structural members having different intervals.

  The present invention has been made in view of the above circumstances, and in a house made of a wooden frame structure, in particular, the inner frame dimensions of different distances between the frames constituting the floor, ceiling, or roof portion are different. Even if it is included, a wooden structure that can be easily and surely inserted between all vertical frame materials with different internal dimensions by preparing one type of synthetic resin foam at the construction site. It is an object to provide a heat insulating material for a frame structure. It is another object of the present invention to provide a heat insulating structure, particularly a floor, ceiling, or roof part, in a wooden frame structure using the heat insulating material.

  The heat insulating material for the wooden frame structure according to the present invention has a standard internal dimension of A (mm) between vertical frame materials using a square material having a width B (mm) × depth K (mm) (> B (mm)) as a base material. It is a frame with a wooden frame structure, and is a heat insulating material made of synthetic resin foam inserted between the vertical frame members in a frame constituting a floor, ceiling, or roof portion of a house, and the heat insulating material Has one or more V-shaped split grooves opened on the rear surface side along the longitudinal direction, and the width dimension a1 (mm) on the front surface side of the heat insulating material is the first non-standard internal dimension Ax (= Smaller than (A + (KB) / 2) (mm)), the width a2 (mm) on the rear surface side is larger than the Ax (mm), and is insulated from one of the V-shaped dividing grooves. By removing a part of the material, between the vertical frame materials having the standard internal dimension A (mm) or the first non-standard internal dimension It is a partial heat insulating material that can be inserted between vertical frame members having a second non-standard internal dimension Ay (mm) different from Ax, and the width dimension ax1 (mm) on the front surface side is a vertical frame member to be inserted Smaller than the standard internal dimension A (mm) or the second non-standard internal dimension Ay (mm), and the rear side width dimension ax2 (mm) is the standard internal dimension A (mm) or the second non-standard internal dimension Ay. A partial heat insulating material larger than (mm) can be obtained.

  In the heat insulating material for the wooden frame structure, the front side width dimension a1 (mm) is narrower than the first non-standard internal dimension Ax (mm) of the frame, and the rear side width dimension a2 (mm) is It is wider than the first non-standard internal dimension Ax of the framework. Therefore, the heat insulating material for the wooden frame structure according to the present invention having the above-described dimensions is the first non-standard internal dimension Ax wider than the standard internal dimension A (mm). Can be easily inserted into non-standard parts. After that, in the process of further pushing, the groove width of the V-shaped dividing groove gradually becomes narrower, and finally, the both sides are inserted between the vertical frame members in a posture where they are in close contact with the side surfaces of the opposing vertical frame members. It will be in the state. Thereby, a reliable heat insulation layer is formed in the first non-standard portion between the vertical frame members.

  Here, as described above, the value of Ax = (A + (KB) / 2) is a base material made of square material having a width B (mm) × depth K (mm) (> B (mm)). In the case of a framework with a wooden framework structure in which the standard internal dimension between vertical frame members is A (mm), the module collapses when the framework is used as a framework for a floor, ceiling or roof of a house It is a dimension (distance between the vertical frame material located on the outermost side and the vertical frame material adjacent to it) in the location which is, ie, the location where it contacts with a wall part.

  It is formed when inserted between vertical frame members having a standard internal dimension A (mm) or between vertical frame members having a second non-standard internal dimension Ay (mm) different from the first non-standard internal dimension Ax. A part of the heat insulating material is removed from any of the V-shaped split grooves to obtain a partial heat insulating material. Also in the obtained partial heat insulating material, the width dimension ax1 (mm) on the front side is smaller than the standard internal dimension A (mm) or the second non-standard internal dimension Ay (mm) between the vertical frame members to be inserted, The width dimension ax2 (mm) on the rear surface side is larger than the standard internal dimension A (mm) or the second non-standard internal dimension Ay (mm). Therefore, the said partial heat insulating material can be easily inserted also in the internal dimension standard part between the said vertical frame materials which comprise a frame, and a 2nd non-standard part. After that, in the process of further pushing in, when the V-shaped split groove is further provided, the V-shaped groove width is gradually reduced, and the V-shaped split groove is further provided. If not, the synthetic resin foam itself forming the partial heat insulating material is slightly deformed, and finally the posture in which both side surfaces of the partial heat insulating material are in close contact with the opposite side surfaces of the vertical frame material, It will be in the state inserted firmly between the vertical frame material of a standard part and a 2nd non-standard part. Thereby, the heat insulation layer is reliably formed also in the standard part between the vertical frame members and the second non-standard part.

  In one aspect of the heat insulating material for a wooden frame structure according to the present invention, the heat insulating material is located at a position where the partial heat insulating material having a size that can be inserted between the vertical frame materials having the standard internal dimension A (mm) is obtained. The character-shaped dividing groove is formed as a first V-shaped dividing groove.

  In this aspect of the heat insulating material, the partial heat insulating material after partly separating from the first V-shaped split groove is used as a space between the vertical frame members in the frame constituting the floor, ceiling, or roof portion of the house. It can be easily inserted into a standard part whose standard internal dimension is A (mm), and a stable heat insulating layer is formed there after the insertion.

  In another aspect of the heat insulating material for a wooden frame structure according to the present invention, the heat insulating material is between vertical frame materials in which the second non-standard internal dimension Ay (mm) is (A−B / 2) (mm). The V-shaped dividing groove is formed as a second V-shaped dividing groove at a position where a partial heat insulating material having an insertable size is obtained.

  The heat insulating material of this aspect is formed by juxtaposing vertical frame materials having the same dimensions for the purpose of reinforcement along one vertical frame material constituting the standard part between the vertical frame materials in the above-described frame. The partial heat insulating material obtained by removing a part using the second V-shaped split groove can be easily inserted between the vertical frame members which are the non-standard parts of 2, and after insertion, A stable heat insulating layer is formed there.

  In still another aspect of the heat insulating material for a wooden frame structure according to the present invention, the heat insulating material is inserted between the vertical frame materials in which the second non-standard internal dimension Ay (mm) is (AB) (mm). The V-shaped dividing groove is formed as a third V-shaped dividing groove at a position where a partial heat insulating material having a possible size is obtained.

  The heat insulating material of this aspect is formed by juxtaposing vertical frame members of the same size for the purpose of reinforcement along both vertical frame members constituting the standard part between the vertical frame members in the frame described above. The partial heat insulating material obtained by removing a part using the third V-shaped dividing groove can be easily inserted between the vertical frame members which are the non-standard part of 2, and after insertion, A stable heat insulating layer is formed there.

  In the heat insulating material for a wooden frame structure according to the present invention, only the first V-shaped split groove may be formed. The heat insulating material having only the first V-shaped split groove can be shared between the first non-standard part and the standard part between the vertical frame members in the frame. A first V-shaped split groove and a second V-shaped split groove may be formed. In the heat insulating material of this aspect, the first non-standard part, the standard part, and the second non-standard part between the vertical frame members in the frame are the same size for the purpose of reinforcement along only one vertical frame member. Can be shared with the second non-standard part in which the vertical frame members are juxtaposed. A first V-shaped dividing groove, a second V-shaped dividing groove, and a third V-shaped dividing groove may be formed. In the heat insulating material of this aspect, the first non-standard part, the standard part, and the second non-standard part between the vertical frame members in the framework are used for reinforcement along one and / or both of the vertical frame members. It can be shared with the second non-standard part in which the vertical frame members of the same size are juxtaposed.

  There is no particular limitation on the size of the frame to which the heat insulating material for the wooden frame structure according to the present invention is attached and the size of the square member as the base material constituting the frame. In the current general wooden frame structure, the dimensions of the vertical frame material and the horizontal frame material as the base material constituting the wooden frame are as follows: the width B = 38 mm, the depth K = 89 mm, and the standard internal dimension A = 417 mm. When the heat insulating material according to the present invention is a frame in the above-described wooden frame structure, and is a heat insulating material made of a synthetic resin foam inserted into a frame constituting a floor, ceiling, or roof portion of a house, The position of the inner side surface of the first V-shaped split groove is a position that is inwardly about 25 to 35 mm from the side edge on the rear surface of the heat insulating material, and the inner side of the second V-shaped split groove. The position of the side surface is a position that is approximately 44 to 52 mm inside from the side edge on the rear surface of the heat insulating material, and the position of the inner side surface of the third V-shaped dividing groove is the side on the rear surface of the heat insulating material. It is a position that enters the inside by about 70 to 77 mm from the edge.

  In the heat insulating material for the wooden frame structure according to the present invention, the opening width on the rear surface side of the V-shaped split groove may be arbitrary, but the vertical frame material constituting the wooden frame has a horizontal width B = 38 mm and a depth K = 89 mm. From the viewpoint of ease of work, the opening width on the rear surface side of the V-shaped split groove is approximately 6 to 10 mm in the case of a wooden frame having a standard internal dimension A = 417 mm between the vertical frame members. desirable. Further, the opening width on the rear surface side of the V-shaped split groove is set to about 6 to 10 mm, whereby the first dimension which is the internal dimension Ax (= (A + (KB) / 2) (mm)). The distance between the vertical frame members when the same square member is juxtaposed as the reinforcing material to one or both of the vertical frame members opposed in the non-standard part, and the vertical frame member opposed in the second non-standard part having the inner dimension Ay It is possible to absorb the difference between the distances between the vertical frame members when the same square member is juxtaposed as a reinforcing member on one or both of them with the opening width of the opening on the rear surface side of the V-shaped split groove, and less Using one type of heat insulating material with a number of V-shaped split grooves, it is possible to cope with all the vertical frame members with different distances that occur in the frame that forms the floor, ceiling, or roof part of the house. It becomes possible.

  Each of the V-shaped dividing grooves described above may be arranged in order of distance from one side edge of the heat insulating material, but considering the strength and balance of the whole heat insulating material, both sides of the heat insulating material It is desirable to disperse them on the edge side. Thereby, the separation work using the V-shaped split groove at the construction site is easy and reliable.

  In the present invention, as a heat insulating structure of a wooden frame using the heat insulating material for a wooden frame structure, a square member having a width B (mm) × depth K (mm) (> B (mm)) is used as a base material. And a non-standard internal dimension Ax (=) that is wider than the standard internal dimension A (mm), and an internal standard part where the internal dimension between the vertical frame members of the frame is A (mm). (A + (KB) / 2) (mm)) and a second non-standard part having a second non-standard internal dimension Ay (mm) different from the non-standard internal dimension Ax And a heat insulating structure in a wooden frame structure in which any one of the above-described heat insulating materials is inserted between the vertical frame members of the frame constituting the floor, ceiling, or roof portion of the house, and the first The heat insulating material is inserted as it is into the non-standard part, and the standard part and the second non-standard part have any one of the V-shapes. Also discloses a heat insulating structure of the timber framework, characterized in that it comprises at least a structure in which portions partially heat insulation after removal of a portion from the material of the groove is inserted.

  By using the heat insulating material for the wooden frame structure according to the present invention, the frame constituting the floor, ceiling, or roof portion of the house made of the wooden frame structure includes the inner dimensions between the vertical frame members at different distances. Even if it exists, it will become possible to insert easily and reliably between all the vertical frame materials from which an internal dimension differs only by preparing the heat insulating material made from one kind of synthetic resin foam in a construction site. Thereby, the ease of heat insulation construction can be obtained, and the inventory management or product management of the heat insulating material can be facilitated.

Five figures which show the state after inserting a partial heat insulating material in the standard part between 1st frame materials, a 1st non-standard part, and a 2nd non-standard part.

  Hereinafter, the present invention will be described based on embodiments. First, the framework at the floor or roof portion in a house having a wooden framework structure will be described.

  FIG. 1 shows the structure of a floor group or a roof rafter group with dimensions (unit: mm) in a standard frame. The frame 1 is assembled in a rectangular shape as a whole by using square members having the same dimensions as the base material as the vertical frame material 2 and the horizontal frame material 3. In general, the square bar has a width B of 38 mm and a depth K of 89 mm. The distance (arrangement module) Z between the centers of the adjacent vertical frame members 2 and 2 in the frame 1 is set to 455 mm. Therefore, the inner portion of the standard portion between the vertical frames shown in FIG. The dimension A is 417 mm. In the floor frame, the vertical frame 2 corresponds to joists, and in the roof rafter frame, the vertical frame 2 corresponds to rafters. Although not shown, a wooden frame structure may be used for the ceiling, but the configuration of the ceiling frame is the same as that of the frame shown in the figure, and in that case, the vertical frame member 2 corresponds to a field edge.

  On the floor, ceiling, and roof in the wooden frame structure, module collapse occurs at the place where the wall portion is engaged. As described above, when a vertical frame material corresponding to a joist having a width of 38 mm is arranged on the outside of the wall where the depth width K of the substrate is 89 mm, the measurement reference line of the arrangement module is at the center of the wall. Because it is set, the module wire at the place where the wall is engaged and the module wire at the standard part are outside by 25.5 mm (= (KB) / 2 = (89-38) / 2) It will shift to. The part shown as F2 in FIG. 1 is the part where the module collapses, and the inner dimension Ax between the vertical frame members here is 442.5 mm (= 417 mm + 25.5 mm). In this invention, this area | region is called a 1st nonstandard part, and the dimension is called 1st nonstandard internal dimension Ax.

  In addition, in the floor, ceiling, and roof in the wooden framework structure, two square members, which are the same base material, are used in a place where structural reinforcement is required. In this case, the distance between the center of the vertical frame member used for one sheet and the center of the vertical frame member used for two sheets is a structural material between the vertical frame members formed by using one or two vertical frame members. The placement module Z = 455 mm. Accordingly, the distance between the vertical frame members here is 398 mm (= A−B / 2 = 417−38 / 2) as shown as the region F3 in FIG. This region is referred to as 1 of the second non-standard part, and its dimension is referred to as a second non-standard internal dimension Ay1. A vertical frame material constituted by using two or two vertical frame materials is also set. In this case, the center-to-center distance between the two vertical frame members used is set to the structural material arrangement module Z = 455 mm. Accordingly, the distance between the vertical frame members here is 379 mm (= A−B = 417−38) as shown as the area F4 in FIG. This region is referred to as 2 of the second non-standard part, and its dimension is referred to as the second non-standard internal dimension Ay2.

  The reinforcement of the structural material with the frame material of the floor, ceiling, and roof in the above-described wooden framework structure is also performed in the above-described module collapse region, that is, the region indicated by F2 in FIG. The areas shown as F5 and F6 in FIG. 2 are the areas. The region F5 is a case where the vertical frame members are used by using two to one in the module collapse region F2, and the distance between the vertical frame members here is 404.5 mm (= Ax−B = 442. 5-38). This region is referred to as a first non-standard part 2 and its dimension is referred to as a first non-standard internal dimension Ax1. Also in the module collapse area F2, a space between the vertical frame members formed by using two or two vertical frame members is set. F6 indicates this region, and the distance between the vertical frame members here is 385.5 mm (= Ax−BB / 2 = 442.5−38−19). This region is referred to as a first non-standard part 3 and its dimension is referred to as a first non-standard internal dimension Ax2.

  That is, when the frame constituting the floor, ceiling, or roof portion of the house in the wooden frame structure is to be insulated using the heat insulating material made of the synthetic resin foam, as described above, the widths of the regions F1 to F6 are provided. It is necessary to prepare six kinds of heat insulating materials. According to the present invention, it is possible to obtain a heat insulating material for a wooden frame structure in which two or three or more kinds of heat insulating materials can be easily adjusted from one heat insulating material at a construction site.

  Fig.3 (a) has shown the example of the heat insulating material 10 by this invention in the cross section of a transversal direction. The synthetic resin foam as the material of the heat insulating material 10 is flexible and compressible, has rebound resilience, and is a vertical frame material when pressed between the vertical frame materials of the frame 1. It is preferable that the side surface of the heat insulating material is in close contact with the side surface. Specifically, a polyolefin resin or polystyrene resin formed by extrusion foam molding or bead foam molding is preferable.

  The heat insulating material 10 is a long member having a required length, and includes left and right side surfaces 11 and 12, a front surface 13, and a rear surface 14 as shown in FIG. 3. Appropriate numbers (three in the figure) of V-shaped split grooves 21, 22, 23 are formed in the longitudinal direction along the side surface. Each V-shaped split groove is open on the rear surface 14 side, and the bottom of each split groove reaches the vicinity of the front surface 13.

  The heat insulating material 10 has a front side width dimension a2 and a rear side width dimension a1 wider than the front side width dimension a1, and the front side width dimension a1 is the inner dimension Ax of the first non-standard portion between the vertical frame members described above. The rear side width dimension a2 is larger than the inner dimension Ax of the first non-standard part. Therefore, the left and right side surfaces 11 and 12 are surfaces inclined in a direction in which the width gradually decreases from the rear surface 14 side toward the front surface 13 side.

  The V-shaped split groove 21 and the V-shaped split groove 22 are formed at positions displaced from the center in the width direction of the heat insulating material 10 toward the left side surface 11, and the V-shaped split groove 23. Is formed at a position displaced from the center in the width direction of the heat insulating material 10 to the right side surface 12 side. In addition, the direction of the center line of each V-shaped split groove 21, 22, 23 is not parallel to the vertical line at the center in the width direction of the heat insulating material 10, but at the center in the width direction of the heat insulating material 10. Slightly inclined in the direction of heading. Therefore, although the thickness of the heat insulating material 10 is substantially the same in the entire width direction, as shown in the figure, the split groove 21 and the split groove 22 are inclined slightly in the lower left direction in the figure, and are V-shaped. The dividing groove 23 has a posture slightly inclined in the lower right direction in the figure. Furthermore, when a part of the heat insulating material 10 is removed from any of the V-shaped split grooves 21, 22, and 23 to form the partial heat insulating material 50, the width dimension ax1 on the front surface 13 side of the partial heat insulating material 50 is The width dimension on the rear surface 14 side is narrower than ax2.

  Specifically, as shown in FIG. 3A, the side surface on the left side surface 11 side of the V-shaped split groove 21 is located at a position of approximately 25 mm from the rear surface side end of the left side surface 11, and its opening width is It is about 7 mm. The left side surface of the V-shaped split groove 22 is located at a position of about 37.5 mm from the right side surface of the V-shaped split groove 21 and the opening width is about 7 mm. Further, the side surface of the V-shaped dividing groove 23 on the right side surface 12 side is located at a position of about 44 mm from the rear surface side end of the right side surface 12, and the opening width is about 7 mm. When the above dimensions are projected onto a horizontal plane, the dimensions are as shown in the figure, and the lateral width a2 on the rear surface 14 side of the heat insulating material 10 is approximately 460.9 mm.

  On the front surface 13 side of the heat insulating material 10, the distance between the front surface side end of the left side surface 11 and the extension of the center line of the V-shaped split groove 21 is approximately 20.9 mm, and the center line of the V-shaped split groove 21 is The distance between the extension portion of the V-shaped split groove 22 and the extension portion of the center line of the V-shaped split groove 22 is approximately 36.4 mm, and the center line of the V-shaped split groove 22 and the center line of the V-shaped split groove 23 The distance between the extended portions is approximately 334.5 mm, and the distance between the extended portion of the center line of the V-shaped split groove 23 and the front side end of the right side surface 12 is approximately 39.8 mm. When the above dimensions are projected onto a horizontal plane, the dimensions are as shown in the figure, and the width a1 on the front surface 13 side of the heat insulating material 10 is approximately 431.0 mm.

  As described above, in the wall frame assembly 1 described with reference to FIG. 1, the inner dimension Ax = 442.5 mm between the vertical frame members 2 and 2 in the first non-standard part F2, and the distance a1 = 431.0 mm < Ax = 442.5 mm. The distance a2 = 460.9 mm> Ax = 442.5 mm. Therefore, the heat insulating material 10 having the above dimensions can be easily inserted between the vertical frame members 2 and 2 in the first non-standard portion F2 from the front surface 13 side, and in the process of further pushing, each V-shaped The opening of each of the split grooves 21, 22, 23 is closed in a gradually narrowing direction, and finally the opening width of each V-shaped split groove 21, 22, 23 is substantially as shown in FIG. It is inserted between the vertical frame members 2 and 2 in the first non-standard part F2 in a state of 0.5 mm.

  Next, the case where the heat insulating material 10 is inserted in the region of the standard part F1 between the vertical frame members where A = 417 mm shown in FIG. 1 will be described. In this case, using the V-shaped split groove 21 from the heat insulating material 10 shown in FIG. 3A, a partial heat insulating material 50a from which the left side portion is removed is used. The width dimension ax1 on the front surface side of the partial heat insulating material 50a is approximately 431-approximately 21 = approximately 410 mm, and is smaller than A = 417 mm. Further, the width dimension ax2 on the rear surface side is approximately 460.9−approximately 24.5 = approximately 436.4 mm, and is larger than A = 417 mm.
