Description

  The present invention relates to a floor grooving assisting tool for a pillar, and more particularly to a floor grooving assisting tool that guides a trimmer in a horizontal direction at a predetermined height when cutting a groove for inserting an end of a floor board on a side surface of a pillar.

  As a tool for precisely forming a notch having a desired shape on the surface of wood, a trimmer is known in which a bit is rotated by an electric motor and cut at a certain depth. This trimmer is generally provided with a rectangular plate-shaped base having a contact surface perpendicular to the axis of the cutting bit, and the length of the bit protruding from the center of the contact surface of the base. The object can be cut at the same depth as that, and the straight portion of the notch can be easily formed by sliding one base side in close contact with a predetermined guide means.

  For example, when a groove (hereinafter referred to as a “floor plate groove”) for inserting the end of the floor plate into the lower part of the pillar and incorporating it is cut, a trimmer equipped with a bit having the same diameter as the thickness of the floor plate is used. Thus, it is possible to form a floor plate groove having an accurate groove width and a uniform depth without requiring an advanced technique. In this case, it is necessary to use a guide means such as a piece of wood having a linear smooth part to guide the cutting direction of the trimmer. For this purpose, extra work is required to attach and remove the guide means to the beam or column with screws or nails. In addition to the need for this, it resulted in leaving holes in the beams and columns.

  On the other hand, Japanese Utility Model Laid-Open No. 1-122902 discloses, as a trimmer guide means, a pair of slide members for sandwiching and fixing a predetermined position of a column and a bottom for guiding the trimmer in the cutting direction. A wood trimmer drilling jig has been proposed in which a sliding plate is provided on a board-shaped substrate. By using this drilling jig, the guide means can be fixed at a predetermined position of the pillar in a simple procedure, and notches of any shape including floor plate grooves can be formed with high accuracy on the wood.

However, when a floor slab groove is formed in a pillar, in order to secure the level of the floor surface on a foundation that is not necessarily horizontal, the pillar is erected on the base beam and then the floor slab groove is It is necessary to determine the position and perform cutting. In this case, the above-described drilling jig is not easy to use in the field where the work space is limited due to the bulk of the substrate, and in addition, it is a method of sandwiching and fixing both sides of the column, so the column is reversed to the beam. In the state of standing in a T-shape, the horizontal beam close to the cutting position becomes an obstacle and it becomes difficult to mount the jig. In addition, even if it can be installed, it takes time and skill to adjust the height position while keeping the cutting direction of the floorboard groove horizontal, so the floorboard is accurately leveled by the floorboard grooves provided in the multiple pillars constituting one room. It was not easy to do.
Japanese Utility Model Publication No. 1-122902

  The present invention is intended to solve the above-described problems. When a floor plate groove is formed on a pillar standing on a beam in the field, a high-precision groove can be easily obtained without requiring advanced techniques. An object is to enable cutting.

  Therefore, the present invention has a smooth horizontal guide part for sliding the lower end surface of the base of the trimmer on the upper surface to guide the bit tip in the horizontal direction at a predetermined height, and the intermediate side surface is the surface to be cut of the column. A guide bar that is arranged horizontally on the upper side of one side of the beam that is the base of the column in a contact state, and a beam that extends downward from the guide bar and contacts the one side of the beam The holding member, a horizontal portion extending from the both ends of the guide bar at right angles and transversely to the longitudinal direction of the beam and extending over the beam, and bent downward from the tip of the horizontal portion so that the inner side surface is the other side surface of the beam And a pair of fixed arms, each of which is provided on each of the fixed arms, and the beam is sandwiched between the beam pressing member by pressing means protruding toward the other side of the beam. Fixed and provided with a floor groove in the pillar for inserting the end of the floor panel This is a cutting aid that assists the cutting operation of the trimmer at the time, and is an adjustment screw for screwing downward into a screw hole that penetrates the horizontal part vertically and supporting the guide bar by contacting the upper surface of the beam at the tip side Each fixed arm is equipped with a cutting position adjusting means that is provided with a screw, and by adjusting the screwing depth of both adjusting screws, the horizontal guide part is adjusted to the desired height and the longitudinal inclination is eliminated. It was set as the floor-plate groove cutting auxiliary tool of the column characterized by this.

  In this way, a simple and compact structure is realized by providing a pair of fixing arms for fixing the guide bar for guiding the cutting operation of the trimmer to the beam by providing cutting position adjusting means each having an adjusting screw. However, in addition to being able to easily attach the guide means for trimming to the part to be cut, setting the cutting height of the floor plate groove and ensuring the horizontal state of the groove can be done very easily without requiring advanced technology. Become.

  In this case, if the pressing means of the fixing arm is formed by screwing a fixing screw into the screw hole penetrating the predetermined position of the hanging part from the outside, it can be easily fixed to the beam by a simple procedure. Furthermore, if the beam holding member is a plate-like member that extends downward from both ends of the guide bar and faces the hanging part, the guide bar can be securely fixed by sandwiching the beam. It will be something.

  Furthermore, in the above-mentioned pillar floor plate groove cutting aid, the horizontal guide portion is formed by the upper surface of a strip-shaped height adjustment plate having a uniform thickness that is detachably provided on the upper portion of the guide bar. After cutting the floor plate groove, the groove width can be expanded by the thickness of the height adjustment plate by cutting again by bringing the base of the trimmer into contact with and sliding on the flat part from which the height adjustment plate has been removed. As a result, when a floor plate having a thickness higher than usual is inserted, it is possible to easily cope with the need to replace the bit with a larger diameter.

  In addition, in the above-described column floor groove cutter cutting auxiliary tool, it extends in the horizontal direction at right angles to the longitudinal direction of the beam from the middle part of the guide bar, and adheres to the top surface of the beam and is adjacent to the surface to be cut of the column. If a side guide member having a side surface in contact with the surface to be cut and having a smooth upper surface is provided, and the cutting direction of the trimmer can be guided on the upper surface, the floor plate is inserted. The grooves can be easily provided at the same height on different side surfaces of the column.

  According to the present invention, in which a pair of fixed arms extending from both ends of the guide bar is provided with cutting position adjusting means that can adjust the height and inclination of the horizontal guide portion, the floor plate groove is formed on the pillar standing on the beam. In the case of forming on site, a highly accurate groove can be easily provided without requiring advanced techniques.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In addition, in this invention, a beam shall refer to the wooden | wooden square | wooden material used as the foundation which mounts members, such as a pillar, arranged horizontally.

  FIG. 1 (A) shows a front view of the cutting aid 1 of the present embodiment, which serves as a guide means for cutting a floor plate groove using a trimmer on a pillar 90 indicated by a one-dot chain line. As described above, when cutting a floor plate groove for inserting (incorporating and incorporating) the end of the floor plate into the lower end portion of the pillar 90, it is usual to use an electric trimmer. In order to determine the height position and secure the horizontal state of the floor plate groove, it is necessary to cut the floor plate groove on-site after the column 90 is erected on the beam 80 indicated by a one-dot chain line.

  In this case, when the trimmer is used on site, the working position and working space are limited, so it is difficult to provide a guide means for guiding the cutting position and the cutting direction, and a groove with an accurate width is cut horizontally. It was not easy to do. Therefore, in the cutting aid 1 of the present embodiment, the guide bar 2 for guiding the trimmer cutting operation is arranged along the lateral beam 80 and the cutting position adjusting means is provided on both ends of the guide bar 2. Thus, the height setting of the horizontal guide portion 20 and the securing of the horizontal state can be easily realized.

  Referring to the plan view of FIG. 1B, the cutting assisting tool 1 is slid in a state where the lower surface of the base of the trimmer is in contact with the horizontal guide to guide the tip position of the bit in a horizontal direction at a predetermined height. Of the beam 90 having the portion 20 and disposed sideways on the upper side of one side (front side) of the beam 80 that is continuous from the surface to be cut in the same plane while the side surface of the column 90 is in contact with the surface to be cut. A guide bar 2 made of a quadrangular prism member, and fixed arms 3 and 3 extending from both ends of the guide bar 2 across the beam 80 at right angles to the longitudinal direction of the beam 80 and horizontally.

  The horizontal guide portion 20 at the top of the guide bar 2 is composed of an upper surface of a height adjusting plate 21 that is made of a horizontally long strip-like member along the longitudinal direction of the guide bar 2 and is detachably fixed by fixing means such as screws. The smooth upper surface of the height adjusting plate 21 and the upper surface (mounting surface) when the height adjusting plate 21 is removed are parallel to the longitudinal direction of the guide bar 2 and are adjusted horizontally to cut the trimmer. The operation can be guided horizontally.

  As shown in the right side view of FIG. 2, the fixing arms 3 and 3 extending from the side surfaces of both ends of the guide bar 2 pass over the beam 80 at right angles to the longitudinal direction of the beam 80 to be fixed. The horizontal portion 31 is a plate-like member that extends horizontally, and a plate-like member that is bent downward from the tip of the horizontal portion 31 and faces the other side (back surface) of the beam 80 on the inner surface side. It consists of a hanging part 32.

  Fixing screws 6 each having a handle 61 on the base end side are respectively provided in screw holes provided through the substantially central portions of the both hanging portions 32 and 32 and laterally screwed from the outside. A disk-shaped contact plate 62 is provided at the front end side of the screw portion 60 at a right angle to the axial direction thereof to constitute a means for pressing the side surface of the beam 80.

  In addition, plate holding members 22 and 22 are provided in which both ends of the guide bar 2 are extended downward from the vicinity of the base ends of the fixed arms 3 and 3 and are in contact with the side surfaces of the beam 80 on the surface. The cutting aid 1 is firmly fixed to the beam 80 by sandwiching the front and back surfaces of the beam 80 laterally between the inner surface and the contact plates 62, 62 of the fixing screws 6 and 6 facing the inner surface. It has become.

  Further, the cutting aid 1 includes a side plate member 25 having a flat plate shape having a side surface that is in close contact with a surface adjacent to a surface to be cut of the column 80 with which the side surface of the central portion of the guide bar 2 abuts. The bar 2 extends from the side surface of the intermediate portion in a direction parallel to the horizontal portion 31 of the fixed arm 3. The side guide member 25 has a top surface that is flush with and flush with the top surface of the horizontal guide portion 20 of the guide bar 2, and is a surface adjacent to the cutting target surface of the column 90 that abuts the side surface of the guide bar 2. When the floor plate groove of the same height is cut horizontally, the operation of the trimmer can be guided.

  Then, an adjustment screw 7 which is a screw member that is screwed and penetrated from above into a screw hole provided at a substantially intermediate position of the horizontal portion 31 of both the fixing arms 3 and 3 is arranged to constitute a cutting position adjusting means. The guide bar 2 and the horizontal guide portion 20 are supported at a desired height by adjusting the screwing depth of the adjusting screws 7 and 7, and the horizontal state in the longitudinal direction can be easily secured. This is a characteristic part of the present invention.

  FIG. 3 shows a perspective view of the cutting aid 1. The members constituting the above-described parts are basically formed by processing prismatic members, and are coupled and fixed to each other by fixing means such as screws. As a result, it is compact and fits in a space equivalent to a prism with a diameter that is one round larger than the diameter of the beam 80 and about five times as long as the diameter of the beam 80 as a whole. It is extremely convenient for use in a narrow space on a construction site. As a material for this prismatic member, an aluminum alloy is excellent from the viewpoint of ease of processing, lightness, cost, strength, and the like.

  Next, the actual usage method and function of the cutting aid 1 according to the present embodiment will be described in detail with reference to FIGS.

  FIG. 4 shows a perspective view of a state in which the cutting aid 1 is mounted and fixed to a beam 80 on which a column 90 to be cut is erected. In order to mount the cutting aid 1, the respective fixing screws 6 of both the fixing arms 3 and 3 are turned so that the distance between the contact plate 62 and the beam pressing member 22 is larger than the diameter of the beam 80. Cover the beam 80 from above and place the corner of the column 80 in close contact with the right angle formed by the side guide member 25 and the guide bar 2 as shown in the figure. Stop.

  Thereafter, the adjusting screws 7 and 7 are turned so that the horizontal portion 20 of the guide bar 2 is secured while maintaining the horizontal state in the longitudinal direction of the guide bar 2 so that the cutting position of the bit becomes the level of the planned floor plate groove. Fine adjustment of the supporting height position is performed, and after fixing this, the fixing screws 6 and 6 are tightened to firmly fix the cutting aid 1 to the beam 80.

  Then, the trimmer is adjusted in advance so that the protruding amount of the bit from the front surface of the base matches the depth of the floor plate groove to be cut, and the entire bottom surface (bottom side surface) of the base is placed on the upper surface of the height adjusting plate 21. A trimmer 100 is applied at a right angle to the side surface of the column 90 to be cut, and the base 110 is in close contact with the side surface of the column 90 and the upper surface of the height adjusting plate 21 as shown in the right side view of FIG. A groove is cut in the column 90 on the side surface of the rotating bit 120 by sliding it sideways (horizontal).

  By cutting the pillar 90 using the trimmer 100 in this way, a floor plate groove m1 as shown in the perspective view of FIG. In this case, since a decorative floor board used in a normal house or the like is usually 12 mm in thickness, when inserting a normal floor board into the pillar 90, by attaching a bit of 12 mm diameter, By sliding the trimmer 100 once, a floor board groove having an accurate groove width is formed horizontally, and the floor board can be incorporated without a gap.

  Some floor boards have a thickness of 15 mm, but when inserting such a floor board, the height adjustment board 21 with a thickness of 3 mm can be installed to easily handle only the bit 120 having a diameter of 12 mm. can do. That is, as shown in FIG. 7, after cutting a groove having a groove width X (12 mm) at one end on the pillar 90, the cutting position can be lowered by 3.0 mm by removing the detachable height adjustment plate 21. By cutting again with 120 as it is, the groove can be expanded by 3 mm in the downward direction and expanded to the groove width Y (15 mm).

  On the other hand, in addition to the floor plate groove m1 provided on the side surface of the column 90 continuous in the same plane from one side surface of the beam 80, when cutting the floor plate groove m2 at the same height on the surface adjacent to the cutting surface at a right angle. As shown in FIG. 8, the cutting aid 1 is used as it is, and the upper surface of the side guide member 25 is simply cut using the trimmer 100 while being used as a cutting guide in the same manner as the height adjusting plate 21. be able to.

  On the other hand, for example, when the upper surface of the foundation is not horizontal, the procedure when the beam 80 is inclined with respect to the horizontal line z will be described with reference to FIGS. In this case, after placing the cutting aid 1 on the portion where the column 90 of the beam 80 is erected and placing it in a temporarily fixed state, the horizontal guide portion 20 on the upper surface of the guide bar 2 using a level or the like is used. By adjusting both the adjusting screws 7 while confirming the horizontal state, the height position can be adjusted while eliminating the inclination of the guide bar 2 in the longitudinal direction (left and right).

  By using the cutting aid 1 according to the present embodiment in such a simple procedure, the floor groove m1 is secured at a predetermined height with high accuracy. Accordingly, it is possible to form floor board grooves with high accuracy in a plurality of pillars constituting one room without requiring highly skilled techniques, and as shown in FIG. 10, the floor board 200 is large in the floor board groove m1 without a gap. It is inserted to ensure an accurate height and levelness. In the above embodiment, the case where the beam pressing member is made of a member different from the guide bar has been described, but the beam pressing member may be composed of one member integrated with the guide bar. Can be implemented in the same manner as described above.

  As described above, when a groove for inserting a floor plate is formed in a field on a pillar standing on a beam, the present invention makes it possible to easily provide a highly accurate groove without requiring a high level of technology. Became.
