Description

  The present invention relates to a completely new wooden frame structure having many merits such as earthquake resistance, workability, and economy.

  A wooden frame structure is mainly composed of vertical members such as pillar members and horizontal members such as foundations and beams. In other words, it is a structure that supports a building with vertical or horizontal materials. The frame construction method has a higher degree of freedom in design than the frame wall construction method, and is easy to extend and renovate, so it has the advantage of making a good house to live for a long time, and has been inherited since ancient times There is a high demand because of the traditional technology.

  Considering this framework construction method in the light of traditional frameworks, it is effective to increase the joints of the structural materials and distribute the force as much as possible to obtain a strong framework. I understand. Even if the number of joints is increased, if the through hole is fixed to the pillar material, an unrecoverable sink may occur when an excessive load is applied, and the thickness of the pillar material may be reduced. It must be thicker than the thread.

  It can also be seen that it is important to balance the structure so that the external force is averaged and dispersed so that the load is not concentrated at a specific location.

  However, if we endeavor to increase the joints in order to increase the strength and avoid uneven distribution of the bearing walls to average out the external force, the wooden frame structure becomes a mere box with no openings. End up. Since this does not function as a house, a horizontal member for forming the opening is installed, but the strength of the opening is lower than that of the other parts.

  In order to suppress a decrease in strength, a horizontal member having a large cross section and a large height must be used.

  However, increasing the strength of the horizontal member itself in this way to obtain the strength of the frame assembly makes the horizontal member heavier and unbalanced with the part that supports the horizontal member. End up. Further, since the horizontal member itself is heavy and the load must be supported, a wide opening cannot be obtained.

  Patent Document 1 below proposes a technique for making the structure around the opening excellent in horizontal strength. This is because the lintels are fixed between the pillars below the horizontal member, and the lower part of the lintel is used as an opening, and the horizontal reinforcing material is fixed between the pillars on the extension line of the lintels. It is the structure which fixed the wall material to the surface of a horizontal member, a lintel, and a horizontal reinforcement. According to this structure, it is supposed that the horizontal force which acts on a lintel can be disperse | distributed and absorbed to a wall material via a pillar material and a horizontal reinforcement material.

  However, in such a configuration, a large load is applied to the joint portion between the horizontal member, the lintel, and the horizontal reinforcing member and the wall member. In other words, the external force applied to the horizontal member is distributed to the joints of the lintels and horizontal reinforcements, but the wall material is affixed to the surface of the joints so that the distributed load is supported reliably. However, it is difficult to disperse and absorb force.

  In addition, since the dimensions of the structural members such as the horizontal members are different from each other, the types of necessary structural members are increased, so that processing and construction cannot be performed easily and the cost is increased. In today's society, there are few skilled workers, so complicated joint processing and construction methods are avoided. In addition, it is not easy to procure large cross-section timber.

  In this regard, for example, as disclosed in Patent Document 2 below, a proposal has been made to unify the dimensions of the through pillar and the horizontal member used while joining the through pillar and the horizontal member. Since the structure surrounds the frame with multiple through-columns, it will be possible to create a through-column that is many times thicker than the width of the horizontal frame, and cross the horizontal frames at the same height. There is a problem that it is not possible to erection and it is not possible to design as freely as the original shaft assembly.

JP 2000-144903 A Japanese Patent Application Laid-Open No. 11-100959

  Therefore, the present invention takes into account the current situation while taking advantage of the wisdom found in traditional frame structures, and has a wooden frame structure that can simultaneously provide various merits such as earthquake resistance, workability, and economy. The main issue is provision.

  The means therefor is a wooden frame structure having a pillar material extending in the vertical direction and a horizontal member joined to the pillar material, and is attached so as to penetrate the upper and lower floors as the pillar material. A horizontal pillar that is joined to a side surface and an outcrop pillar whose head is exposed, and a main horizontal member that is installed at the upper end position of each floor eave is provided as the horizontal member. And a secondary horizontal member that is installed in parallel with a gap between the main material and both ends of the main horizontal material and the secondary horizontal material are joined to the side surfaces of the column material, In between the main horizontal member and the secondary horizontal member, a fitting panel composed of a structural panel in which the entire periphery is fitted in a groove formed in the intermediate portion in the width direction is fixed, This is a wooden frame structure in which the materials are joined by fixing structural hardware.

  In this wooden frame structure, the main horizontal member and the secondary horizontal member are installed between the through-columns, between the outcrop columns, or between the through-columns and the outcrop columns, with both ends joined to the side surfaces of the column materials, A fitting panel, which is a structural panel that bears the force, is fitted in a portion surrounded by the material and the horizontal member in a state where the entire peripheral edge is bitten into the groove. Further, the column member and the horizontal member are fixed by a structural hardware that bears the force.

  As described above, since the horizontal member is fixed to the side surface of the column member, it is not necessary to use a long timber for the horizontal member. For this reason, a joint can be eliminated from the horizontal member.

  Moreover, since the horizontal member is fixed to the side surface of the column member, it is possible to suppress the action of a force that compresses the column member in the axial direction when an external force is applied. For this reason, the strength of the pillar material can be secured and the occurrence of buckling can be prevented.

  And since a joint is unnecessary for a horizontal member as mentioned above, the intensity | strength of horizontal member itself is securable.

  This horizontal member is composed of the main horizontal member and the secondary horizontal member, which are fixed to the side surfaces of the column members, respectively, and the fitting panel is fitted into the middle part in the width direction and integrated. Therefore, the force is dispersed at the joint portion between the column member and the horizontal member, and the force is also dispersed in the fitting panel integrated with them. For this reason, high strength can be obtained without using a large cross-section timber for the main horizontal member and the secondary horizontal member. In other words, it is not necessary to use timber with a large cross section or high height for the main horizontal member and the sub horizontal member, but by using the same timber for the main horizontal member and the sub horizontal member, Contributes to the unification of materials.

  Thus, the strength of the horizontal member portion can be obtained without using a timber having a large cross section, and the strength of the column member portion can be ensured by using an outcrop column as the column member. For this reason, it is also possible to obtain a wide opening which was impossible in the past.

  Further, since the column member and the horizontal member are joined with the structural hardware, complicated joint processing is not necessary. From this point, the strength of the fixing portion between the column member and the two horizontal members arranged in parallel can be secured, the processing itself is easy, and the joining operation is also easy. It is also possible to prevent the occurrence of irreparable sinking, such as when using threading.

  Also, the cross section of the column member and the horizontal member can be the same. For this reason, it is possible to unify structural materials.

Furthermore, since it is not necessary to use timber with a large cross section for the column material and horizontal member used, the number of m ³ used can be reduced.

  Bonding with structural hardware can be either rigid connection or pin connection, but in any case, the construction is done by building through pillars and necessary outcrop pillars, and then fixing and fitting panels And fixing of the main horizontal member are performed in order, which is an easy operation that can be performed even with simple construction. Since the fitting panel is fixed in parallel with the fixing of the column member and the horizontal member, the foundation is completed at the same time as the shaft assembly is completed, and a simple and quick construction can be realized, and the construction period can be shortened. Further, if the floor panel, ceiling panel, wall base material, etc. are fixed in parallel, further rapid construction can be expected.

  As described above, according to the present invention, since the structure in which the main horizontal member and the secondary horizontal member are fixed to the side surfaces of the column members is employed, the number of joints can be increased and the force can be distributed. Further, since the fitting panel is integrated between the main horizontal member and the secondary horizontal member, the force can be distributed also in the fitting panel. In addition, since the main horizontal member is installed at the position of the upper end of each building eaves, it can be arranged in a well-balanced manner in the shaft assembly. For this reason, it is possible to obtain a structurally good balance and prevent a load from being concentrated on a specific portion.

  As a result, the strength can be improved by the configuration of the shaft assembly itself, not the strength improvement of only a small tip with added value due to the use of hardware or the like, and good earthquake resistance can be obtained. In addition, since the pillars and horizontal members are joined with structural hardware, there is no need for complicated joints and penetrations, and processing and construction are easy, and timber used as pillars and horizontal members is easy. The cross-sectional dimensions can be unified. For this reason, it becomes a wooden frame structure advantageous also in terms of workability and economy.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

  FIG. 8 is a perspective view in which the fitting panel 61 is removed from the shaft assembly 11 shown in FIG. 1 to facilitate understanding of the joining state of the base 31, the column member 41, and the horizontal member 51. Hereinafter, FIG. 8 is also referred to. The structure of the shaft set 11 will now be described.

First, the column member 41 will be described.
As the pillar material 41, it has the through pillar 42 attached so as to penetrate the upper and lower floors, and the pipe pillar 43 which is only in each floor, and timbers having the same size and the same cross section are used for these. Is done. These column members 41 are fixed on the foundation 21 together with the base 31, but the column members 41 to which a pulling force is applied like the through columns 42 and the tube columns 43 are anchor bolts (not shown) embedded in the foundation 21. ).

  Of the through pillars 42 and the pipe pillars 43, necessary ones are set to the outcrop pillars 41 a where the horizontal members 51 are joined to the side surfaces and the heads are exposed.

  The outcrop column 41a will be described with reference to the schematic diagram of FIG. 9. Among the column members shown in FIG. 9, the outcrop column 41a is a through column 101 and tube columns 102 and 103 which are shaded. In other words, the horizontal members 104 and 105 are fixed between the standing through column 101 and the tube columns 102 and 103 by joining both ends thereof to the through column 101 and the tube columns 102 and 103 from the left and right directions. Yes. In addition, another pipe column 103 is erected on the horizontal member 104 or the outcrop column 41 a laid horizontally between the through column 101 and the tube column 102, and another horizontal member is provided to the tube column 103. 105 is fixed by joining both ends thereof in the left-right direction. In this manner, a plurality of rectangular spaces surrounded by the base 106, the through pillar 101, the pipe pillars 102, 103, and the horizontal members 104, 105, and the through pillar 101, the pipe pillars 102, 103, and the horizontal members 104, 105 are formed. Has been. The horizontal members 104 and 105 are formed of a single piece, and no joint is provided.

  When such an outcrop column 41 a and the horizontal members 104 and 105 without joints are provided, the load related to the shaft group is a large number of through columns 101 and tube columns 102 and 103 as the outcrop column 41 a and the horizontal members 104 and 105. The dispersed load is firmly supported by the through column 101 and the tube columns 102 and 103, and the space becomes firm, and a high strength shaft can be obtained.

  The through-column 42 and the tube column 43 as the outcrop column 41a, and other necessary through-columns 42 and the tube column 43 are formed to have a predetermined length so as to be appropriately disposed based on a desired floor plan, Predetermined processing required for joining with other members is performed on the part where the horizontal member 51 is joined and other parts.

Next, the horizontal member 51 will be described.
As the horizontal member 51, between the main horizontal members 52 and 53 installed at the upper end position of each floor eave height, that is, the position where the torso or beam is generally installed, and the main horizontal members 52 and 53. And secondary horizontal members 54 and 55 installed in parallel with a gap therebetween.

The main horizontal members 52 and 53 and the secondary horizontal members 54 and 55 may be made of timber having the same size and the same cross-section as the column member 41. Of the main horizontal members 52 and 53, the shaft 11 The main horizontal member 52 and the base 31 arranged on the outer peripheral portion of the cross section are, for example, 105 × 120 and 120 × 135 larger than that when the pillar material is 105 or 120 square, A timber in which one of the vertical weeds a and b has the same size and the other has a larger size is used (see FIGS. 10 and 18).

  That is, as shown in FIG. 10A, the main cross member 52 and the base 31 having a rectangular cross section are used in a horizontally long shape, and one side surface is joined to the side surface of the column member 41 so as to be flush with each other. This is for convenience in fixing the floor panel.

  The main horizontal member 53 disposed inside the shaft assembly 11 is a timber having a cross section of the same size and the same shape as that of the column member 41. For example, a material having a high height can be used.

  On the other hand, even for the outer peripheral portion of the shaft assembly 11, a timber having a cross section of the same size and the same shape as that of the column member 41 is used for the secondary horizontal member 54. For this reason, as shown in FIG. 10B, both side surfaces of the follower 54 are flush with the side surfaces of the column members 41.

  The secondary horizontal members 54 and 55 have different installation heights depending on whether they are the outer peripheral part or the inner part of the shaft assembly 11, and will be described separately.

  First, the secondary horizontal member 54 on the outer peripheral portion of the shaft assembly 11 will be described. In the opening, that is, the portion where the window frame 71 is not provided, the installation position is set to an appropriate height that divides each floor eaves into three equal parts. The That is, as shown in FIG. 8, above the base 31, below the upper end position of the first floor eaves, above the upper end position of the first floor eaves, and below the upper end position of the second floor eaves It is installed above the upper end position of the second-floor eave height and below the upper end position of the third-floor eave height at a position spaced from the main horizontal member 52 by a predetermined height.

  On the other hand, in the portion where the window frame 71 is fitted, the secondary horizontal member 54 is installed at a position where the upper end or the lower end of the window frame 71 is received (see FIG. 7).

  Next, the internal subordinate horizontal member 55 will be described. The internal subordinate horizontal member 55 is installed at such a height that a ceiling is formed when a ceiling panel is fixed to the lower end thereof.

  Further, the main horizontal member 53 and the secondary horizontal member 55 inside the shaft assembly 11 are joined to the outcrop column 41a as much as possible.

  The main horizontal members 52 and 53 and the secondary horizontal members 54 and 55 are formed in a predetermined length so as to be appropriately arranged based on a desired floor plan, and are joined to the column member 41. A predetermined process required for joining with other members is performed on the other parts.

Next, the fitting panel 61 will be described.
The fitting panel 61 is integrally joined to the column member 41 and the horizontal member 51 in a state of being bitten. In other words, as one of the processes necessary for joining with the other members described above, the groove portions 44 and 56 for joining the fitting panel 61 are formed in the column member 41 and the horizontal member 51. As shown in FIG. 10, the grooves 44 and 56 are set to an appropriate depth with a width corresponding to the peripheral edge of the fitting panel 61 fitted to the intermediate portion in the width direction of the column member 41 and the horizontal member 51. ing.

  FIG. 11 is a front view showing a portion in FIG. That is, it is a front view showing a portion surrounded by the column member 41, the main horizontal member 52, and the secondary horizontal member 54 on the outer peripheral portion of the shaft assembly 11, and the entire peripheral edge of the fitting panel 61 is as shown in this figure. , And fitted into the column 41 and the horizontal member 51.

  As the fitting panel 61, a panel having a predetermined thickness having a necessary strength capable of bearing such a load is used, and studs 62 are fixed in advance on both surfaces. The spacer 62 has a length that fits between the main horizontal member 52 and the secondary horizontal member 54, and has a smaller cross section than the column member 41. As shown in FIG. Based on this, the height from the surface of the fitting panel 61 is appropriately set so as to be a double-sided large wall, a large wall and a true wall, and a double-sided true wall.

  Further, as shown in FIG. 13, at the portion where the distance between the column members 41 becomes long, the connecting column 57 that connects the main horizontal member 52 and the secondary horizontal member 54 with a gap between them is provided as the column member. Depending on the distance between 41, one or more are fixed apart. The connecting column 57 is formed of timber having a cross section of the same size and shape as the column material. Moreover, it has the groove part 57a which fits into the peripheral edge of the panel 61 fitted in both sides | surfaces, and although not shown in figure, the required process for fixing a structural metal object is given to both ends.

  In addition, in FIG.11, FIG12, FIG.13, 75 represented by the virtual line is a wall base material.

  FIG. 14 is an exploded perspective view of the portion B in FIG. That is, it is an exploded perspective view showing the main horizontal member 53, the secondary horizontal member 55 and the fitting panel 61 inside the shaft assembly 11, and the main horizontal member 53 is provided on both surfaces of the fitting panel 61 as shown in this figure. The intermediate column 62 having a length that fits between the main horizontal member 55 and the sub horizontal member 55 is fixed in advance, and the intermediate portion in the length direction of the main horizontal member 53 and the sub horizontal member 55 is the same as the column member 41. A connecting column 57 made of timber having a large and identical cross section is fixed as required. The connecting column 57 is also subjected to a groove 57a for biting the periphery of the fitting panel 61 and necessary processing for fixing the structural hardware.

  15 is a front view of a beam portion inside the shaft assembly 11, that is, a portion having the main horizontal member 53, the secondary horizontal member 55, and the fitting panel 61, and FIG. 16 is a cross-sectional view thereof. If necessary, as shown in FIG. 11 and FIG. 12, an appropriate panel can be fixed to the surface to obtain desired effects such as reinforcement, soundproofing and heat insulation.

  In addition, the floor panel 81 and the ceiling panel 82 are fixed to the main horizontal member 53 and the secondary horizontal member 55 fixed as described above. That is, as shown in FIG. 17, the floor panel 81 is directly fixed to the upper surfaces of the main horizontal members 52 and 53, and the ceiling panel 82 is directly fixed to the lower surface of the secondary horizontal member 55. FIG. 17 shows the main horizontal member and the secondary horizontal material portion of the first floor part or the second floor part. As shown in this figure, the main horizontal material 52 on the outer peripheral portion of the shaft assembly 11 is fixed horizontally long. Therefore, a portion protruding inward from the column member 41 is obtained. For this reason, the floor panel 81 can be firmly fixed, and at the same time, the burning can be omitted. As shown in FIGS. 5 and 6, the floor panel 82 is fixed to the base, and the main horizontal member 52 erected at the upper end position of the third floor eaves is shown in FIGS. 5, 6, and 6. As shown in FIG. 7, the connecting panel 83 made of a structural panel equivalent to the floor panel 82 is fixed, and the firing is omitted. In the figure, reference numeral 75 denotes a wall base material.

Next, the structural hardware will be described.
As the structural hardware, various well-known joining hardware are used. Although not shown, the structural hardware includes those made of cast iron and resin in addition to those made of metal such as a steel plate. In addition to a rigid coupling, a pin coupling with a restoring force may be used. In addition, reinforcing hardware can be additionally used as necessary.

  As shown in FIGS. 18 to 21, the shaft assembly 11 made of the structural material as described above includes a column member 41, a horizontal member 51, a connecting column 57, a fitting panel 61, and a wall base material 75. The floor panel 81, the ceiling panel 82, the coupling panel 83, and the structural hardware are joined together in this order from the bottom.

That is, first, as shown in FIG. 18, the base 31 and the through column 42 are fixed on the foundation 21. The through column 42 is directly fixed to the anchor bolt of the foundation 21 with a column base metal as a structural joint metal. The base 31 is fixed so as to be horizontally long. In the figure, a one-dot chain line is a position where the through pillar 42 is built, and a two-dot chain line is a position where the main horizontal member 52 is fixed on the outer peripheral portion of the shaft assembly 11.
When the base 31 and the through pillar 42 are fixed, the state is as shown in FIG.

  Next, as shown in FIG. 20, the pipe column 43, the main horizontal members 52, 53, the secondary horizontal members 54, 55, the fitting panel 61, the floor panel 81, the ceiling panel 82, and the coupling panel 83 are positioned below. In order from what is to be fixed, it is fixed by fitting with the structural hardware.

  Specifically, the pipe column 43 is fixed on the base 31 with structural hardware, and the periphery of the fitting panel 61 is fitted into the through-hole 42, the pipe column 43, and the groove portion 56 formed in the base 31. Next, the secondary horizontal members 54 and 55 installed above the base 31 are fixed using the structural hardware between the column 42 and the pipe column 43, and at the same time, the secondary horizontal members 54 and 55 are formed. The groove 56 is fitted to the peripheral edge on the upper end side of the fitting panel 61.

  In a portion other than the opening, the fitting panel 61 is fixed in the same manner on the slave horizontal member 54 installed above the base 31.

  Next, the sub horizontal member 54 is fixed to the lower part of the upper end position of the first floor eaves with a structural hardware. In a portion other than the opening, the fitting panel 61 is fitted and fixed to the upper end.

  Subsequently, the fitting panel 61 is fixed on the slave horizontal member 54 in the same manner as described above.

  At this time, as shown in FIG. 21, the connecting column 57 is vertically fixed to the portion that requires the connecting column 57 with the joining hardware on the subordinate horizontal member 54. Since the groove 57a is formed in the connecting column, the fitting panel 61 is fixed so as to be fitted into the groove 57a. Then, the main horizontal member 52 is fixed to the upper end position of the first floor eaves with a structural hardware (see FIG. 20). At this time, the main horizontal member 52 on the outer peripheral portion of the shaft assembly 11 is fixed so as to be horizontally long as shown in FIG. Then, after the secondary horizontal member 55, the fitting panel 61 and the main horizontal member 53 are fixed inside the shaft assembly 11, the ceiling panel 82 is fixed to the lower surface of the secondary horizontal member 55, and the main horizontal member 52, A floor panel 81 is fixed to the upper surface of 53. The ceiling panel 82 and the floor panel can be fixed at the time of construction of necessary facilities such as electricity.

  In this way, the shaft assembly 11 is completed by repeating the work of joining and fixing all the structural members. And since the fitting panel 61 is being fixed to parts other than an opening part, the foundation | substrate will also be completed simultaneously.

  In the shaft assembly 11 configured as described above, the joint portion between the column member 41 and the horizontal member 51 is compared with the case where one horizontal member is installed at the upper end of each floor eaves as shown in FIG. As shown in the schematic diagram, the number of joints is remarkably increased, and the fitting panel is integrally fitted between the main horizontal members 52 and 53 and the secondary horizontal members 54 and 55 installed between the column members 41. Due to the presence of 61, the force can be well dispersed.

  Moreover, since the place where the main horizontal members 52 and 53 are installed is the upper end of the height of each floor eaves, the high-strength configuration comprising the main horizontal members 52 and 53, the vertical and horizontal members 54 and 55, and the fitting panel 61 is Can be evenly arranged. For this reason, it is possible not to apply an excessive load to a specific location. Similarly, the fitting panel 61 is equally arranged in a balanced manner and functions as a load bearing wall. In other words, it can be structured like a collection of boxes.

  Further, since the structural member is used for joining the column member 41, the horizontal member 51, and the connecting column 57, and a construction method such as threading is not used, the occurrence of indentation can be suppressed.

  As a result, even with the shaft assembly 11 having a large living room and garage as described above, the strength can be improved and the earthquake resistance can be enhanced.

  The effect of improving the strength is that the through column 42 and the tube column 43 are used as the outcrop column 41a, and the force is distributed to a large number of joints so that the dispersed load is firmly supported by the outcrop column 41a of the through column 42 and the tube column 43. It is promoted by doing.

  In addition, since the main horizontal member 53 and the secondary horizontal member 55 installed inside the shaft assembly 11 are joined to such an outcrop pillar 41a, the strength can be further increased.

In addition, a high-strength opening is formed by not using a through-hole construction method using structural hardware for joining the column members 41 and the like, and by using the main horizontal members 52 and 53, the secondary horizontal members 54 and 55, and the fitting panel 61. Can be obtained. For this reason, it has not been possible so far by standardizing the cross-sectional dimensions of the base 31, the column 41, and the horizontal member 51, or by making one of the cross-sectional dimensions the same as described above. It can be reduced to two types. In addition, since it is not necessary to use timber having a large cross section for the column material 41 and the horizontal member 51 to be used, the number of m ³ used can be reduced.

  In addition, the horizontal member 51 does not require a joint and does not require joint processing, so that the processing load can be reduced and precut processing can be performed at low cost.

  As a result, material procurement is facilitated and processing is facilitated. In addition, the weight of individual pillars and horizontal members is reduced, and transportation and construction are simplified. For this reason, the construction period can be shortened.

  As described above, it is possible to obtain the shaft assembly 11 having not only earthquake resistance but also excellent workability and economy.

  In addition, since the height of the follower frame 54 at the outer peripheral portion of the shaft assembly 11 is set at a position for receiving the upper end and the lower end of the window frame, there is no need to separately provide a window frame base material, and the workability and economy are improved. This is advantageous in terms of sex.

  Further, the ceiling space is formed by the main horizontal member 53, the secondary horizontal member 55, the fitting panel 61, and the floor panel 81 and the ceiling panel 82 or the coupling panel 83, and may require a fire beam or a joist. Since there is not, a comparatively wide ceiling space can be obtained. For this reason, construction such as ventilation, air conditioning, and electricity can be performed with high freedom, and the work itself is easy. In addition, since the ceiling space is partitioned and subdivided by the main horizontal member 53, the secondary horizontal member 55, the connecting column 57, and the fitting panel 61, the propagation of sound can be suppressed by the partition. As a result, soundproofing between rooms can be improved and a comfortable living space can be obtained.

  Furthermore, in the shaft set 11, by using a movable partition panel inside the shaft set 11, it is possible to easily cope with a change in the floor plan. In other words, there are advantages such as a high degree of design freedom and ease of extension and renovation, which are not found in the frame wall construction method.

The column material of the present invention corresponds to the through column 42 and the tube column 43 in the above-described embodiment,
