Description

  The present invention relates to a method for constructing a staircase skirting board.

  As a configuration of an indoor staircase in a building such as a house, there is known a structure having a plurality of tread boards and a plurality of kick boards, and a stair baseboard attached along the tread boards and the kick boards. For example, in the technique described in Patent Document 1, a horizontal baseboard and a vertical baseboard are used as staircase baseboards, and the horizontal baseboard and the vertical baseboard are joined together by fastening, Each of the baseboards is connected by a connecting tool using a mounting groove provided on the back surface of the vertical baseboard.

  Further, when the horizontal baseboard and the vertical baseboard are joined together by fastening, the appearance is remarkably lowered unless the end surfaces of the baseboards are accurately matched. Therefore, when constructing stairs, after constructing the basic structure of the stairs, such as a tread board and a kick board, cutting work of the ends of each baseboard is performed according to the actual stairs dimensions. That is, the fastening process at the construction site is carried out.

  However, in order to improve the efficiency of building construction, it is desirable to eliminate the work on site as much as possible, and pre-cut one end of the horizontal baseboard and vertical baseboard before bringing them into the field, and the other side on the site after bringing them into the field. A method of cutting is generally used. In this case, since particularly accurate alignment is required for the nose side of the footboard, the end of the nose side is pre-cut in the horizontal baseboard and the vertical baseboard, and the opposite side, that is, the horizontal baseboard is used at the construction site. The kick plate side and the lower end side of the vertical baseboard are each cut in the field.

JP 2013-44197 A

  However, as described above, in the method of pre-cutting the end of the nose side of the horizontal skirting board and the vertical skirting board, and cutting the opposite side (the side skirting board side and the bottom side of the vertical skirting board) in the field, the stairs It is necessary to adjust the position of the cut position on the back side, i.e., on the side opposite to the nose, which is inconvenient in terms of workability.

  This invention is made | formed in view of the said situation, and makes it the main objective to provide the construction method of the staircase baseboard which can improve the workability | operativity of the construction of the staircase baseboard in a construction site. .

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, for ease of understanding, the reference numerals of the corresponding components in the embodiments of the invention are appropriately shown in parentheses, but are not limited to the specific configurations shown in parentheses.

The first invention is

A horizontal baseboard attaching step for attaching the horizontal baseboard to the upper surface side of the tread board after cutting the on-site cut surface of the horizontal baseboard,
It is characterized by having.

  In the conventional construction method, both the horizontal baseboard and the vertical baseboard have a pre-cut surface on the nose side and an on-site cut surface on the opposite side (see FIG. 6), whereas in the construction method of the present invention, the vertical baseboard The nose side (upper side) is the pre-cut surface, the opposite side (lower side) is the field cut surface, and for horizontal baseboards, the kick board side is the pre-cut surface, and the opposite nose side is the field cut surface (Fig. 4). Here, looking at the difference between the prior art and the present invention, regarding the on-site cutting of the horizontal baseboard, in the prior art, the cutting position on the back side (the kick plate side) is adjusted with respect to the near side (nosing side). In the present invention, the cutting position on the near side (nosing side) is adjusted with respect to the far side (the kick plate side) and the near side is cut. Cutting work is performed. In this case, in the present invention, it is not necessary to adjust the position of the horizontal skirting board on the back side (the kick board side), and the work relating to the on-site cutting of the horizontal skirting board can be easily performed as compared with the prior art. As a result, it is possible to improve the workability of the construction of the stair baseboard at the construction site.

  As a supplement, according to the construction method, the fastening is performed by a combination of the pre-cut surface and the on-site cut surface at the joint portion between the horizontal baseboard and the vertical baseboard. In this case, it can be said that the pre-cut surface has a relatively high processing accuracy and the on-site cut surface has a relatively low processing accuracy, so that a decrease in the accuracy of the fastening is suppressed compared to the case where the on-site cut surfaces are joined together. It is possible.

  In a second invention, in the horizontal baseboard cutting step, in a state where the vertical baseboard is attached to the front surface side of the kick board, the position of the on-site cut surface in the horizontal baseboard is adjusted, and then The on-site cut surface is cut.

It can be carried out. In this case, it is possible to easily adjust the position of the cut surface of the horizontal baseboard.

  According to a third aspect of the present invention, the step board has a configuration in which a nose projects from the kick board, and a recess (22b) that accommodates the nose of the step board is pre-processed on a side surface of the vertical baseboard. In the vertical baseboard cutting step, the cutting operation of the on-site cut surface in the vertical baseboard is performed in accordance with the dimension between the upper surface of the lower stepboard and the lower surface of the upper nose of the upper stepboard. In the horizontal baseboard cutting step, the vertical baseboard is attached to the front side of the kick board so that the step nose of the stepping board is accommodated in the recess, and in this state, the site in the horizontal baseboard The position of the cut surface is adjusted, and then the on-site cut surface is cut.

  In the configuration in which the step nose of the tread board protrudes from the kick board, a recess for accommodating the nose is formed in the vertical baseboard. In this case, the concave portion can be used as a reference for positioning the vertical baseboard and the horizontal baseboard, and the accuracy of the fastening can be increased.

It is characterized by having.

  In the fourth invention, as a difference from the first invention, the pre-cut surface of the vertical baseboard and the on-site cut surface are upside down. However, even in the present invention, unlike the conventional construction method, the cutting position on the near side (nosing side) is adjusted with respect to the on-site cut of the horizontal baseboard (on the side of the kick board) as a reference. The cutting operation on the front side is performed. In this case, also in the present invention, the position adjustment or the like on the back side (the kick plate side) is not necessary for the horizontal baseboard, and the work related to the on-site cutting of the horizontal baseboard can be easily performed as compared with the prior art. As a result, it is possible to improve the workability of the construction of the stair baseboard at the construction site.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In this embodiment, the structure and construction method of an indoor stair that connects an upper floor part and a lower floor part in a multi-storey building will be described in detail. FIG. 1 is a perspective view showing the configuration of the staircase 10, and FIG. 2 is a longitudinal sectional view of the staircase 10.

  As shown in FIGS. 1 and 2, the staircase 10 has a plurality of stepping plates 11 and a plurality of kicking plates 12. The tread plate 11 and the kick plate 12 are provided between the beam portions 13 fixed to the left and right side walls, and are fixed to the beam portion 13 via the base members 14 and 15. Each tread plate 11 is provided at a predetermined interval in the vertical direction, and the kick plate 12 is fixed between the rear end surface of the lower step plate 11 and the lower surface of the upper step plate 11. The tread board 11 is provided such that the nose protrudes in front of the kick board 12.

  Long plate-like stair skirting boards 20 are attached to the side walls on both sides of the stairs. The stair skirting board 20 includes a horizontal skirting board 21 provided along the upper surface (treading face) of the tread board 11 and a vertical skirting board 22 provided along the front surface of the kick board 12. The vertical baseboard 22 is joined to each other by fastening.

  In detail about the staircase skirting board 20, the side skirting board 21 is formed with a lip 21a that is fastened to both ends in the longitudinal direction. In addition, the vertical baseboard 22 is formed with a mouth end 22 a that is fastened to both ends in the longitudinal direction, and a rectangular recess 22 b that accommodates the nose of the footboard 11. The inclination angles of the mouthpieces 21a and 22a of the baseboards 21 and 22 are 45 °.

  The stair baseboard 20 may be formed with a continuous surface pattern such as a notch, a groove, and a chamfer extending in the longitudinal direction on the surface serving as a decorative surface. For example, in the configuration shown in FIG. 3, notches 23 are formed at corners of the horizontal baseboard 21 and the vertical baseboard 22. In this case, since the horizontal skirting board 21 and the vertical skirting board 22 are joined together by fastening, it is possible to suitably form a design in which the notches 23 are continuous from the top to the bottom of the staircase 10 unlike the joining by the butt. it can. In addition, the staircase skirting board 20 is good to have the same cross-sectional shape as the room skirting board provided in a room.

  Here, when the staircase 10 is constructed, a horizontal baseboard 21 and a vertical baseboard 22 are prepared, and the horizontal baseboard 21 and the vertical baseboard 22 are fixed in a state where the tread board 11 and the kick board 12 are assembled. Is done. At this time, the actual staircase dimensions after assembling the tread board 11 and the kick board 12 are measured at the construction site, and the horizontal baseboard 21 and the vertical baseboard 22 are cut in accordance with the measurement dimensions. Thereby, the length dimension of each baseboard 21 and 22 is matched with an actual step size.

  In addition, as shown in FIG. 4, the horizontal baseboard 21 and the vertical baseboard 22 are precut in which the end of one end is precut before being brought to the site as shown in FIG. The end of the other end has a cut surface that is cut in the field after being brought into the field. In this case, particularly in the present embodiment, in order to further improve the workability at the construction site with respect to the staircase skirting board 20, the upper side of the vertical skirting board 22 is the pre-cut surface and the lower side is the field cutting surface, and the horizontal skirting board 21 Is the precut surface on the side of the kick plate (back) and the cut side on the nose side (front). In FIG. 4, the portion removed by the on-site cut is shown with dots. The recessed portion 22b of the vertical baseboard 22 is pre-processed before being brought into the field.

  Next, the construction procedure of the staircase skirting board 20 will be described. Here, the on-site cutting work of the horizontal baseboard 21 and the vertical baseboard 22 will be described in detail with reference to FIG. FIG. 5A shows the on-site cutting work (vertical baseboard cutting process) of the vertical baseboard 22, and FIG. 5B shows the on-site cutting work (horizontal baseboard cutting process) of the horizontal baseboard 21.

  When performing on-site cutting of the vertical baseboard 22 after the tread board 11 and the kick board 12 are assembled, as shown in FIG. 5A, the upper surface of the lower tread board 11 and the lower surface of the upper tread board 11 The separation distance L1 is measured, and based on the separation distance L1, fastening processing is performed on the lower end portion on the opposite side to the precut surface of the vertical baseboard 22. In this case, as an adjustment operation of the cutting position, a position A that is L1 away from the lower surface of the concave portion 22b of the vertical baseboard 22 is marked, and the vertical baseboard is cut from the position A by using a tool or the like at an oblique 45 ° cut line. 22 is cut.

  Thereafter, when the on-site cutting of the horizontal baseboard 21 is performed, the on-site-cut vertical baseboard 22 is put on the front side of the kick board 12 as shown in FIG. At this time, the vertical baseboard 22 is fixed to the girder 13 using an adhesive, a hidden nail, or the like. And as adjustment work of a cutting position, the tip of a precut surface is applied to the kick board 12 in the state which made the horizontal baseboard 21 parallel to the tread board 11, and the upper front-end | tip part of the vertical baseboard 22 in the horizontal baseboard 21 Mark a position B that matches (fastening tip). After that, the horizontal baseboard 21 is cut from the position B by using a tool or the like along an oblique 45 ° cut line.

  Then, the horizontal baseboard 21 is attached to the upper surface side of the tread board 11. At this time, the horizontal baseboard 21 is fixed to the girder 13 using an adhesive, a hidden nail, or the like. Thereby, the end of the horizontal baseboard 21 and the vertical baseboard 22 is joined by fastening.

  When the construction method of this embodiment is compared with a prior art, it differs in the following points. In the construction method of the prior art, as shown in FIG. 6, for the horizontal baseboard 31 and the vertical baseboard 32, the stair nose side is the pre-cut surface and the opposite side is the on-site cut surface. Therefore, when the horizontal baseboard 31 is cut in the field, the cutting position on the back side (the kick plate side) is adjusted with reference to the near side (nosing side), and the cutting work on the back side is performed. In this case, there is a concern that the workability of construction is poor.

  On the other hand, in the construction method of the present embodiment, for the vertical baseboard 22, the nose side (upper side) is a pre-cut surface, the opposite side (lower side) is a field cut surface, and the horizontal baseboard 21 is a kick board. The side is a pre-cut surface, and the opposite side of the nose is the on-site cut surface. Therefore, when the horizontal baseboard 21 is cut in the field, the cutting position on the near side (nosing side) is adjusted with reference to the back side (the kick plate side) and the cutting operation on the near side is performed. In this case, it is not necessary to adjust the position of the horizontal skirting board 21 on the back side (the kick board side), and the work relating to the on-site cutting of the horizontal skirting board 21 can be easily performed as compared with the prior art.

  Instead of fixing the vertical skirting board 22 with an adhesive or a hidden nail before actual cutting of the horizontal skirting board 21 (main fixing), a tape or the like can be simplified before the horizontal skirting board 21 is cut on site. The vertical baseboard 22 is temporarily fixed using a fixing means, and then the vertical baseboard 22 is fixed (mainly fixed) using an adhesive or a hidden nail after the on-site cutting of the horizontal baseboard 21 is completed. It may be.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  For the vertical baseboard 22, the nose side (upper side) is the precut surface, the opposite side (lower side) is the site cut surface, and for the horizontal baseboard 21, the kick plate side is the precut surface, and the opposite nose side is the site cut surface. It was. In this case, when the horizontal baseboard 21 is cut in the field, the cutting position on the near side (nosing side) is adjusted with respect to the far side (the kick plate side) and the cutting operation on the near side is performed. Position adjustment or the like on the side (the kick plate side) becomes unnecessary, and the work related to the on-site cutting of the horizontal baseboard 21 can be easily performed as compared with the conventional technique. As a result, the workability of the construction of the stair baseboard 20 at the construction site can be improved.

  Moreover, according to the said construction method, in the junction part of the horizontal baseboard 21 and the vertical baseboard 22, a clasp is performed by the combination of a precut surface and a field cut surface. In this case, it can be said that the pre-cut surface has a relatively high processing accuracy and the on-site cut surface has a relatively low processing accuracy, so that a decrease in the accuracy of the fastening is suppressed compared to the case where the on-site cut surfaces are joined together. It is possible.

  In the horizontal baseboard cutting step (see FIG. 5B), with the vertical baseboard 22 attached to the front side of the kick board 12, the position adjustment of the on-site cut surface in the horizontal baseboard 21 is performed, The cutting work of the on-site cut surface was performed. In the state where the vertical baseboard 22 is attached to the front side of the kick board 12, the back side of the horizontal baseboard 21 is brought into contact with the kick board 12, and the front side is aligned with the vertical baseboard 22, and cut in the field. The position of the surface can be adjusted. In this case, the position adjustment of the field cut surface of the horizontal baseboard 21 can be easily performed.

  In more detail, in the vertical baseboard cutting process (see FIG. 5A), the cut surface on the site is adjusted in accordance with the dimension between the upper surface of the lower stepping plate 11 and the lower surface of the upper nose of the stepping plate 11. In the horizontal baseboard cutting step (see FIG. 5 (b)), the vertical baseboard 22 is attached to the front side of the kick board 12 so that the step nose of the step board 11 is accommodated in the recess 22b. In that state, the position of the on-site cut surface in the horizontal baseboard 21 was adjusted, and then the on-site cut surface was cut. In this case, the concave portion 22b of the vertical baseboard 22 can be used as a reference for positioning the vertical baseboard 22 and the horizontal baseboard 21, and the accuracy of fastening can be increased.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  -It is also possible to change the construction procedure of the stair baseboard 20 as follows. FIG. 7 is a diagram showing the horizontal baseboard 21 and the vertical baseboard 22 before the site cut together with the structure of the stairs. In FIG. 7, as a difference from FIG. 4 described above, the precut surface of the vertical baseboard 22 and the on-site cut surface are upside down. Further, the tread plate 11 is flush with the kick plate 12 at the nose portion, and does not protrude from the kick plate 12.

  That is, in the vertical skirting board cutting process, the lower side of both ends of the vertical skirting board 22 is a pre-cut surface and the upper side is a field cut surface, and the field cut surface is cut. Further, in the horizontal skirting board cutting step, in the horizontal skirting board 21, the kick plate side of the both ends 21a is a pre-cut surface, and the nose side is a site cut surface, and the site cut surface is cut. In the vertical baseboard attaching process, the vertical baseboard 22 is attached to the front side of the kick board 12 after cutting the on-site cut surface of the vertical baseboard 22, and in the horizontal baseboard attaching process, the site of the horizontal baseboard 21 is attached. After cutting the cut surface, the horizontal baseboard 21 is attached to the upper surface side of the tread board 11.

  Even in this construction method, unlike the conventional construction method, the cutting position on the near side (nosing side) is adjusted with respect to the back side (the kick plate side) with respect to the on-site cutting of the horizontal baseboard 21. At the same time, the cutting work on the front side is performed. Therefore, the position adjustment or the like on the back side (the kick plate side) of the horizontal skirting board 21 is not necessary, and the work relating to the on-site cutting of the horizontal skirting board 21 can be easily performed as compared with the prior art. As a result, the workability of the construction of the stair baseboard 20 at the construction site can be improved.

  In the above embodiment, the angle of inclination of the mouthpieces 21a and 22a of the horizontal baseboard 21 and the vertical baseboard 22 is 45 °, but other angles may be used.
