Description

[Technical Field]

[0001] The present invention relates to a reinforcing material for a liner plate and a reinforcing structure for a liner plate. [Background technology]

[0002] Reinforcement structures for increasing the strength of liner plates have been studied. Examples of construction methods using liner plates include stacking multiple plates vertically and fixing them by applying a load vertically downward after erecting them. In these cases, the liner plates must be strong enough to withstand vertical loads without buckling. Therefore, there is a strong demand for a reinforcing structure for liner plates that can withstand vertical loads.

[0003] Patent Documents 1 and 2 disclose reinforcing structures for liner plates. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 04-016693 [Patent Document 2] Japanese Patent Application Publication No. 07-042478 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the liner plate reinforcing material and reinforcing structure disclosed in Patent Document 1, the strength can be increased by providing a reinforcing material inside the frame, but there is no disclosure of its ability to withstand vertical loads. Furthermore, according to the liner plate reinforcing material and reinforcing structure disclosed in Patent Document 2, the liner plate reinforcing material and reinforcing structure can withstand vertical loads by attaching a buckling prevention material to the surface of the liner plate. However, attaching the buckling prevention material requires work such as drilling holes in the surface of the liner plate and welding various components, and the reinforcing material must be corrugated to match the surface shape of the liner plate, which is not economical. Furthermore, when a liner plate with a buckling prevention material already attached is installed, the weight of the liner plate increases, making installation difficult.

[0006] The present invention was devised in consideration of the above-mentioned problems, and its purpose is to provide a reinforcing material for liner plates and a liner plate reinforcing structure that are economical and easy to install, as well as have improved strength against vertical loads. [Means for solving the problem]

[0007] The liner plate reinforcement material in the first invention is a liner plate reinforcement material fixed to a liner plate that is erected in the vertical direction, and is characterized by comprising a first steel connection portion fixed to the upper flange of the liner plate, a steel base portion extending in one direction from one end connected to the first connection portion, and a second steel connection portion connected to the other end in the extension direction of the base and fixed to the lower flange of the liner plate.

[0008] The reinforcing material for liner plates in the second invention is characterized in that, in the first invention, it further comprises a reinforcing rib fixed to the base and the first connection portion or the second connection portion which is flange-shaped relative to the base.

[0009] The reinforcing material for a liner plate in the third invention is characterized in that, in the first or second invention, at least one of the first connecting portion and the second connecting portion has a stepped shape in the vertical direction.

[0010] The reinforcement for a liner plate in the fourth invention is characterized in that, in the first or second invention, the first connection portion or the second connection portion is fixed to the upper flange of the liner plate via the lower flange of an upper liner plate connected above the liner plate, or is fixed to the lower flange of the liner plate via the upper flange of a lower liner plate connected below the liner plate.

[0011] The liner plate reinforcement structure of the fifth invention is characterized by comprising a liner plate erected vertically, a first steel connection portion fixed to the upper flange of the liner plate, a steel base having one end connected to the first connection portion and extending vertically, and a second steel connection portion connected to the other end of the base and fixed to the lower flange of the liner plate. [Effects of the Invention]

[0012] According to the first to fourth inventions, the liner plate reinforcement comprises a first steel connection part fixed to the upper flange of the liner plate, a steel base part extending in one direction, and a second steel connection part fixed to the lower flange of the liner plate. Therefore, it is possible to resist vertical loads via the base part regardless of the surface shape of the base part. This improves the cost efficiency and ease of construction when constructing the liner plate, as well as improving strength against vertical loads.

[0013] In particular, according to the second aspect of the present invention, a reinforcing rib is further provided that is fixed to the flange-shaped first or second connection portion of the base. This allows vertical loads applied to the first or second connection portion to be easily transmitted to the base via the reinforcing rib. This further improves the strength of the liner plate against vertical loads when it is installed.

[0014] In particular, according to the third aspect of the present invention, at least one of the first and second connecting portions has a vertically staggered shape. Therefore, by vertically offsetting the connecting portion from the reinforcing ring that connects the liner plates, the liner plate reinforcing member does not interfere with the reinforcing ring, and the liner plate reinforcing member can be attached simultaneously with or after joining the liner plate and the reinforcing ring. This further improves the ease of installation of the liner plate.

[0015] In particular, according to the fourth aspect of the present invention, the first connecting portion or the second connecting portion is fixed to the upper flange or the lower flange via the upper liner plate or the lower liner plate. Therefore, the liner plate reinforcement can be attached simultaneously with or after joining the liner plate vertically. This further improves the ease of installation of the liner plate.

[0016] According to the fifth aspect of the present invention, the liner plate reinforcement structure includes a first steel connection portion fixed to the upper flange of the liner plate, a steel base portion extending in one direction, and a second steel connection portion fixed to the lower flange of the liner plate. This allows the structure to withstand vertical loads via the base regardless of the surface shape of the base. This improves the cost efficiency and ease of construction of the liner plate, as well as improving strength against vertical loads. [Brief explanation of the drawings]

[0018] Hereinafter, an example of a liner plate reinforcing material 1 and a liner plate reinforcing structure 100 as an embodiment of the present invention will be described in detail with reference to the drawings. In each drawing, a first horizontal direction X is defined, one direction perpendicular to the first horizontal direction X is defined as a second horizontal direction Y, and a direction perpendicular to each of the first horizontal direction X and the second horizontal direction Y is defined as a vertical direction Z. The configurations in each drawing are shown schematically for the purpose of explanation, and for example, the size of each component and the size comparison between components may differ from those shown in the drawings.

[0019] (Liner plate reinforcement 1) An example of a reinforcing material 1 for a liner plate according to this embodiment will be described with reference to the drawings.

[0020] The liner plate reinforcement 1 is a member for reinforcing a known liner plate. As shown in Fig. 1, the liner plate reinforcement 1 includes a base 11, a first connecting portion 12, and a second connecting portion 13. When constructed on site, the liner plate reinforcement 1 is erected such that the base 11 is aligned along the vertical direction Z, with the first connecting portion 12 facing upward and the second connecting portion 13 facing downward.

[0021] In the liner plate reinforcement 1, the upper flange 22 of the liner plate is fixed at the first connection portion 12, and the lower flange 23 of the liner plate is fixed at the second connection portion 13 (see FIG. 3). Furthermore, a steel base portion 11 extending in one direction is connected to the first connection portion 12 at one end in the extension direction and to the second connection portion 13 at the other end in the extension direction. In this case, regardless of the surface shape of the base portion 11, it is possible to resist a load in the vertical direction Z via the base portion 11. This allows for improved economy and ease of construction in the construction of liner plates, as well as improved strength against loads in the vertical direction Z.

[0022] The liner plate reinforcement material 1 may further include, for example, a flange-shaped first connection portion 12 or second connection portion 13 and a reinforcing rib 14 fixed to the base portion 11. In this case, a load in the vertical direction Z applied to the first connection portion 12 or second connection portion 13 is easily transmitted to the base portion 11 via the reinforcing rib 14. This allows for further improvement in strength against a load in the vertical direction Z when installing the liner plate.

[0023] <Base 11> The base 11 is a steel member that extends in one direction. For example, as shown in FIG. 1, the base 11 is a steel pipe that extends in the vertical direction Z, and can withstand a load in the vertical direction Z.

[0024] For example, one end of the base 11 in the extension direction is connected to the first connection part 12, and the other end of the extension direction is connected to the second connection part 13. The base 11 is a member to which a load in the vertical direction Z applied to the liner plate is transmitted via the first connection part 12 or the second connection part 13.

[0025] For example, as shown in Figures 2(a) and 2(b), a steel pipe that is square when viewed in the vertical direction Z is used for the base 11. Any shape that can withstand a load in the vertical direction Z may be used for the base 11, and for example, in addition to a circular steel pipe, steel sections including H-shaped steel and L-shaped steel may also be used.

[0026] <First connection portion 12> The first connecting portion 12 is a steel member fixed to the upper flange of the liner plate. The first connecting portion 12 is connected to one end of the base portion 11 in the extension direction, as shown in FIG. 1 , for example. The first connecting portion 12 may be connected to the base portion 11 by, for example, bolting or welding. The first connecting portion 12 can transmit, for example, a load in the vertical direction Z applied to the upper flange of the liner plate to the base portion 11.

[0027] As shown in Figures 2(a) and 2(b), for example, the first connecting portion 12 is made of a flat steel plate extended in a horizontal direction perpendicular to the vertical direction Z (a planar direction including the first horizontal direction X and the second horizontal direction Y). The first connecting portion 12 is, for example, in the shape of a flange whose diameter is expanded in the horizontal direction perpendicular to the vertical direction Z relative to the base portion 11. The first connecting portion 12 may have any shape that can transmit the load in the vertical direction Z applied to the upper flange of the liner plate to the base portion 11, and may be made of steel, such as an H-shaped steel or an L-shaped steel.

[0028] The first connection portion 12 may be formed with, for example, one or more first bolt holes 120. The first connection portion 12 is fixed to the upper flange of the liner plate via bolts inserted through the first bolt holes 120, for example.

[0029] <Second connection portion 13> The second connection portion 13 is a steel member fixed to the bottom flange of the liner plate. The second connection portion 13 is connected to the other end of the base portion 11 in the extension direction, as shown in FIG. 1 . The second connection portion 13 may be connected to the base portion 11 by, for example, bolting or welding. The second connection portion 13 can transmit, for example, a load in the vertical direction Z applied to the bottom flange of the liner plate to the base portion 11.

[0030] As shown in Figures 2(a) and 2(b), for example, the second connecting portion 13 is made of a flat steel plate extending in a horizontal direction perpendicular to the vertical direction Z. That is, the second connecting portion 13 may be disposed in parallel to the first connecting portion 12. The second connecting portion 13 is, for example, in the shape of a flange whose diameter is enlarged in the horizontal direction perpendicular to the vertical direction Z relative to the base portion 11. The second connecting portion 13 may have any shape that can transmit the load in the vertical direction Z applied to the bottom flange of the liner plate to the base portion 11, and for example, shaped steel including H-shaped steel or L-shaped steel may be used.

[0031] The second connection portion 13 may be provided with, for example, one or more second bolt holes 130. The second connection portion 13 is fixed to the lower flange of the liner plate via bolts inserted through the second bolt holes 130, for example.

[0032] <Reinforcing rib 14> The reinforcing rib 14 is fixed to the base 11 and the first connecting portion 12 or the second connecting portion 13, which has a flange shape relative to the base 11. The reinforcing rib 14 may be fixed to the base 11 and the first connecting portion 12 or the second connecting portion 13, for example, by bolting or welding.

[0033] The reinforcing rib 14 is, for example, a flat plate reinforcing rib 141 fixed to the flat plate-shaped first connecting portion 12 or the second connecting portion 13. The flat plate reinforcing rib 141 extends, for example, in the vertical direction Z. For example, one or more flat plate reinforcing ribs 141 may be fixed to one first connecting portion 12 or one second connecting portion 13. Note that the reinforcing rib 14 may be fixed to the base 11 and the first connecting portion 12 or the second connecting portion 13 during on-site construction.

[0034] (Liner plate reinforcing structure 100) Next, an example of the liner plate reinforcing structure 100 according to this embodiment will be described with reference to the drawings.

[0035] The liner plate reinforcing structure 100 includes a liner plate reinforcing material 1 and a liner plate 2, as shown in FIG.

[0036] In the liner plate reinforcement structure 100, the first connection portion 12 is fixed to the upper flange 22 of the liner plate 2, and the second connection portion 13 is fixed to the lower flange 23 of the liner plate 2. Furthermore, a steel base 11 extending in one direction is connected to the first connection portion 12 at one end in the extension direction and to the second connection portion 13 at the other end in the extension direction. In this case, regardless of the surface shape of the base 11, it is possible to resist a load in the vertical direction Z via the base 11. This allows for improved economy and ease of construction when constructing the liner plate 2, as well as improved strength against a load in the vertical direction Z.

[0037] <Liner plate 2> The liner plate 2 is a known steel liner plate.

[0038] The liner plate 2 includes, for example, a plate body 21, an upper flange 22, and a lower flange 23. In the liner plate 2, the plate body 21, the upper flange 22, and the lower flange 23 may be continuous, or may be connected to each other by bolts or welding.

[0039] For example, during on-site construction, the liner plate 2 is erected with the upper flange 22 facing upward and the lower flange 23 facing downward so that the plate body 21 is aligned along the vertical direction Z. In other words, the liner plate 2 and the liner plate reinforcement 1 are arranged so as to be approximately parallel to each other.

[0040] <Plate body 21> The plate body 21 is a rectangular steel plate that has been corrugated and is linear in plan view. The upper end of the plate body 21 is continuous with the upper flange 22, and the lower end is continuous with the lower flange 23, for example.

[0041] <Upper flange 22> The upper flange 22 is a portion that continues from the upper end of the plate body 21. The upper flange 22 may be formed by bending the upper end of the plate body 21, or may be formed by fixing a steel material separate from the plate body 21 to the upper end of the plate body 21 by bolting or welding.

[0042] The upper flange 22 has, for example, a flat upper plate portion 221. The upper flange 22 may have any shape that allows it to be joined to the first connecting portion 12.

[0043] The upper flange 22 may be provided with, for example, one or more upper connecting bolt holes 222. The liner plate 2 is connected to another liner plate above via, for example, bolts B22 inserted through the upper connecting bolt holes 222.

[0044] <Bottom flange 23> The lower flange 23 is a portion that continues from the lower end of the plate body 21. The lower flange 23 may be formed by bending the lower end of the plate body 21, or may be formed by fixing a steel material separate from the plate body 21 to the lower end of the plate body 21 by bolting or welding.

[0045] The lower flange 23 has, for example, a flat lower plate portion 231. The lower flange 23 may have any shape that allows it to be joined to the second connecting portion 13.

[0046] The lower flange 23 may be provided with, for example, one or more lower connecting bolt holes 232. The liner plate 2 is connected to another liner plate below via, for example, a bolt B23 inserted through the lower connecting bolt hole 232.

[0047] <Base 11> The base 11 is disposed so as to be substantially parallel to the plate body 21. For example, the base 11 may be spaced apart from the plate body 21, or at least a portion of the base 11 may be in contact with the plate body 21.

[0048] <First connection portion 12> The first connecting portion 12 is fixed to the upper flange 22 via a bolt B22 inserted into the first bolt hole 120, for example.

[0049] The first connecting portion 12 may be fixed to the upper flange 22, for example, via a bolt B22 inserted through an upper connecting bolt hole 222 pre-drilled in the upper flange 22 to connect another liner plate upward and the first bolt hole 120. In this case, there is no need to newly provide a bolt hole in the upper flange 22 to fix the first connecting portion 12. This allows for further improvement in the economy of the installation of the liner plate 2.

[0050] <Second connection portion 13> The second connection portion 13 is fixed to the lower flange 23 via a bolt B23 inserted into the second bolt hole 130, for example.

[0051] The second connection portion 13 may be fixed to the lower flange 23, for example, via a bolt B23 inserted through a lower connecting bolt hole 232 and the second bolt hole 130 that are pre-drilled in the lower flange 23 to connect another liner plate downward. In this case, there is no need to newly provide a bolt hole in the lower flange 23 for fixing the second connection portion 13. This allows for further improvement in the economy of the installation of the liner plate 2.

[0052] (Modification of the liner plate reinforcing structure 100) As shown in Figures 4(a) to 4(c), the liner plate reinforcement structure 100 further includes an upper reinforcing ring 223 of shaped steel that joins the liner plate 2 and the upper liner plate 2' above in the vertical direction Z, and a lower reinforcing ring 233 of shaped steel that joins the liner plate 2 and the lower liner plate 2'' below in the vertical direction Z. Note that Figure 4(b) is a partially enlarged view of the area around the upper reinforcing ring 223 in Figure 4(a), and Figure 4(c) is a partially enlarged view of the area around the lower reinforcing ring 233 in Figure 4(a).

[0053] Here, the first connection portion 12 has a stepped shape in the vertical direction Z in side view, and is spaced apart from the upper reinforcing ring 223 of the H-shaped steel. Furthermore, the second connection portion 13 has a stepped shape in the vertical direction Z in side view, and is spaced apart from the lower reinforcing ring 233 of the H-shaped steel. In this case, by installing the first connection portion 12 offset in the vertical direction Z relative to the upper reinforcing ring 223 or the lower reinforcing ring 233, the liner plate reinforcement member 1 does not interfere with the upper reinforcing ring 223 or the lower reinforcing ring 233, and the liner plate reinforcement member 1 can be attached simultaneously with or after joining the liner plates 2, 2', 2'' and the reinforcing rings 223, 233. This further improves the ease of installation of the liner plate 2.

[0054] <Upper Reinforcement Ring 223> The upper reinforcing ring 223 is a separate member from the upper flange 22, and is fixed to the surface of the upper flange 22. The upper reinforcing ring 223 may be made of, for example, H-shaped steel or other steel including L-shaped steel.

[0055] 4(b), the upper reinforcing ring 223 may have one or more ring holes 223a formed therein. The upper reinforcing ring 223 is joined to the liner plate 2 by fixing the upper flat plate portion 221 via bolts B22 inserted through the ring holes 223a and bolt holes 231'a formed in the lower flat plate portion 231' of the upper liner plate 2' above, and the lower flat plate portion 231' of the upper liner plate 2' is fixed above and joined to the upper liner plate 2'.

[0056] <Lower Reinforcement Ring 233> The lower reinforcing ring 233 is a separate member from the lower flange 23, and is fixed to the surface of the lower flange 23. The lower reinforcing ring 233 may be made of, for example, an H-shaped steel or other steel including an L-shaped steel.

[0057] The lower reinforcing ring 233 may have one or more ring holes 233a formed therein, as shown in Fig. 4(c), for example. The lower reinforcing ring 233 is joined to the liner plate 2 by fixing the lower flat plate portion 231 via bolts B23 inserted through the ring holes 233a and bolt holes 221''a formed in the upper flat plate portion 221'' of the lower liner plate 2'' below, and the upper flat plate portion 221' of the lower liner plate 2'' is fixed below and joined to the lower liner plate 2''.

[0058] <First connection portion 12> The first connection portion 12 has, for example, a stepped shape in the vertical direction Z. The first connection portion 12 is, for example, an S-shaped or Z-shaped metal fitting in a side view.

[0059] The first connecting portion 12 is joined to one end of the base portion 11 via, for example, a bolt B12. The first connecting portion 12 is fixed to the upper reinforcing ring 223 via a bolt B22, as shown in FIG. 4(b), for example.

[0060] The first connecting portion 12 may be fixed to the upper reinforcing ring 223 via bolts B22 inserted through ring holes 223a drilled in advance in the upper reinforcing ring 223 to connect the upper reinforcing ring 223, the upper flat plate portion 221, and the lower flange (lower flat plate portion 231') of the upper liner plate 2', upper connecting bolt holes 222 drilled in advance in the upper flat plate portion 221, and bolt holes 231'a drilled in advance in the lower flat plate portion 231'. In this case, it is not necessary to newly provide bolt holes in the upper reinforcing ring 223 for fixing the first connecting portion 12. This allows for further improvement in the economy of construction of the liner plate 2.

[0061] Additionally, the first connection portion 12 is fixed to the upper flange 22 via the lower flange of the upper liner plate 2'. In this case, the liner plate reinforcement 1 can be attached simultaneously with or after joining the liner plates 2, 2' in the vertical direction Z. This further improves the ease of installation of the liner plate 2.

[0062] <Second connection portion 13> The second connection portion 13 has, for example, a stepped shape in the vertical direction Z. The second connection portion 13 is, for example, an S-shaped or Z-shaped metal fitting in a side view.

[0063] The second connection part 13 is joined to the other end of the base part 11 via, for example, a bolt B13. The second connection part 13 is fixed to the lower reinforcing ring 233 via, for example, a bolt B23, as shown in FIG. 4(c).

[0064] The second connection portion 13 may be fixed to the lower reinforcing ring 233, for example, via a bolt B23 inserted through a ring hole 233a pre-drilled in the lower reinforcing ring 233 to connect the lower reinforcing ring 233, the lower flat plate portion 231, and the upper flange (upper flat plate portion 221'') of the lower liner plate 2'', a lower connecting bolt hole 232 pre-drilled in the lower flat plate portion 231, and a bolt hole 221''a pre-drilled in the upper flat plate portion 221''. In this case, there is no need to newly provide a bolt hole in the lower reinforcing ring 233 to fix the second connection portion 13. This further improves the economy of the construction of the liner plate 2.

[0065] In addition, the second connection portion 13 is fixed to the lower flange 23 via the upper flange of the lower liner plate 2''. In this case, the liner plate reinforcement material 1 can be attached simultaneously with or after joining each liner plate 2, 2'' in the vertical direction Z. This further improves the ease of installation of the liner plate 2.

[0066] <Reinforcing rib 14> 4(a), the reinforcing rib 14 may be a folded plate reinforcing rib 142 fixed to the bent folded plate surface of the first connection portion 12 or the second connection portion 13, which have a stepped shape in the vertical direction Z. In this case, the load in the vertical direction Z applied to the first connection portion 12, the upper reinforcing ring 223, the second connection portion 13, or the lower reinforcing ring 233 is easily transmitted to the base portion 11 via the folded plate reinforcing rib 142. This allows for further improvement in the strength of the liner plate 2 against loads in the vertical direction Z when it is installed.

[0067] One or more folded plate reinforcing ribs 142 may be fixed to one first connection portion 12 or one second connection portion 13, for example.

[0068] In addition, as shown in Figure 5(a), the liner plate reinforcement structure 100 may have the first connection portion 12 and the upper flange 22, which are stepped in the vertical direction Z, fixed to the lower flange of the upper liner plate 2' via bolt B22, and the flat second connection portion 13 and the lower flange 23 (lower flat plate portion 231) fixed to the bolt B23. In addition, as shown in Figure 5(b), the liner plate reinforcement structure 100 may have the first connection portion 12 and the upper flange 22 (upper flat plate portion 221) fixed to the bolt B22, and the second connection portion 13 and the lower flange 23, which are stepped in the vertical direction Z, fixed to the upper flange of the lower liner plate 2'' via bolt B23.

[0069] According to this embodiment, the liner plate reinforcement 1 comprises a first steel connection portion 12 fixed to the upper flange 22 of the liner plate 2, a steel base portion 11 extending in one direction (vertical direction Z), and a second steel connection portion 13 fixed to the lower flange 23 of the liner plate 2. Therefore, it is possible to resist a load in the vertical direction Z via the base portion 11 regardless of the surface shape of the base portion 11. This allows for improved economy and ease of construction of the liner plate 2, as well as improved strength against a load in the vertical direction Z.

[0070] Furthermore, according to this embodiment, the base 11 is further provided with a reinforcing rib 14 fixed to the flange-shaped first connecting portion 12 or the second connecting portion 13. Therefore, a load in the vertical direction Z applied to the first connecting portion 12 or the second connecting portion 13 is easily transmitted to the base 11 via the reinforcing rib 14. This allows for further improvement in strength against a load in the vertical direction Z when the liner plate 2 is installed.

[0071] Furthermore, according to this embodiment, at least one of the first connecting portion 12 and the second connecting portion 13 has a stepped shape in the vertical direction Z. Therefore, by installing the first connecting portion 12 and the second connecting portion 13 offset in the vertical direction Z with respect to the upper reinforcing ring 223 (lower reinforcing ring 233) that connects each liner plate 2, 2' (2, 2'') to each other in the vertical direction Z, the liner plate reinforcement material 1 does not interfere with the upper reinforcing ring 223 (lower reinforcing ring 233), and the liner plate reinforcement material 1 can be attached simultaneously with or after joining each liner plate 2, 2', 2'' and each reinforcing ring 223, 233. This further improves the ease of installation of the liner plate 2.

[0072] Furthermore, according to this embodiment, the first connection portion 12 or the second connection portion 13 is fixed to the upper flange 22 or the lower flange 23 via the upper liner plate 2' or the lower liner plate 2''. Therefore, the liner plate reinforcement material 1 can be attached simultaneously with or after joining each liner plate 2, 2' (2, 2'') in the vertical direction Z. This further improves the ease of installation of the liner plate 2.

[0073] Furthermore, according to this embodiment, the liner plate reinforcement structure 100 comprises a steel first connection portion 12 fixed to the upper flange 22 of the liner plate 2, a steel base portion 11 extended in one direction (vertical direction Z), and a steel second connection portion 13 fixed to the lower flange 23 of the liner plate 2. Therefore, it is possible to resist a load in the vertical direction Z via the base portion 11 regardless of the surface shape of the base portion 11. This allows for improved economy and ease of construction in the construction of the liner plate 2, as well as improved strength against loads in the vertical direction Z.

These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
