Description

[Technical Field]

[0001] The present invention relates to a method for joining panels used in construction when pouring concrete. [Background technology]

[0002] Generally, battens are used to join formwork panels (Patent Documents 1 to 3). Although battens are sometimes used to increase the rigidity of formwork panels, when the rigidity of formwork panels is ensured by fastening them with pipe material, the battens only function to temporarily fix the formwork panels. Not only is the nailing required to attach the battens a significant burden, but the bulky formwork panels with battens attached make them difficult to transport and store. Furthermore, removing the nails is also a significant burden, meaning that most of the battens end up as waste after construction. Patent Documents 4 and 5 propose joining members for connecting form panels. [Prior art documents] [Patent documents]

[0013] An embodiment of the method for joining form panels according to the present invention will be described below.

[0014] FIG. 1 is a side view of a main part of a structure in a construction state, illustrating a method for joining form panels according to an embodiment of the present invention. In the method for joining form panels according to this embodiment, form panels 10 used in construction when pouring concrete are joined using joining members 20 instead of battens. As shown in Figure 1, in the construction of formwork for a concrete structure, a pair of walls 10a and 10b are erected on a foundation 1, and concrete is poured into a space 2 between the inner surface of wall 10a and the inner surface of wall 10b. In the beam section, the wall body 10c is supported by a beam support member 3, and the beam support member 3 is held by a pipe support 4. A fastening member 5 is attached to the pair of wall bodies 10a, 10b to maintain a constant distance between the pair of wall bodies 10a, 10b. The fastening member 5 is composed of a separator 5a, a pair of cones 5b, a pair of fastening member bodies 5c, and a pair of washers 5d. The walls 10a, 10b, and 10c are constructed by joining multiple form panels 10. Generally, battens are used to join the form panels 10. Although battens are sometimes used to increase the rigidity of the form panels 10, in this embodiment, vertical pipe members 6a are arranged at predetermined intervals on the outer surfaces of the form panels of the walls 10a and 10b, and these vertical pipe members 6a (6) are fastened with horizontal pipe members 6b (6) to ensure the rigidity of the form panels 10. The pipe members 6 support the load applied to the form panels 10 when concrete is poured. FIG. 1 shows the joining members 20 as a joining member 20 that joins two form panels 10 so that they are flush with each other, and a joining member 20 that joins the interior corners of the join between the two form panels 10.

[0015] FIG. 2 is a diagram showing an embodiment of a form panel and a joining member used in the method for joining form panels according to the present invention. FIG. 2( a ) shows a first forming panel 11 , a second forming panel 12 , and a connecting member 20 . As shown in Figure 2(a), a panel-side first engaging portion 11a is formed on the first form panel outer surface 11s of the first form panel 11, and a panel-side second engaging portion 12a is formed on the second form panel outer surface 12s of the second form panel 12, which is joined adjacent to the first form panel 11. The joining member 20 is attached by engaging with the first panel side engaging portion 11a formed on the lower part of the first formwork panel 11 and the second panel side engaging portion 12a formed on the upper part of the second formwork panel 12. FIG. 2(b) is a plan view of the second form panel 12 shown in FIG. 2(a). As shown in FIG. 2(b), the panel-side first locking portion 11a and the panel-side second locking portion 12a are formed by panel-side ridge-like convex portions.

[0016] FIG. 2( c ) is a side view of the joining member 20 . The joining member 20 has a first member-side locking portion 21a that engages with the first panel-side locking portion 11a, and a second member-side locking portion 22a that engages with the second panel-side locking portion 12a. The component-side first locking portion 21a and the component-side second locking portion 22a are formed as component-side groove-shaped recesses.

[0017] FIG. 2(d) is a side view showing a state in which the joining member 20 is engaged with the first form panel 11 and the second form panel 12. As shown in FIG. As shown in Figure 2(d), the first locking portion 21a on the component side is engaged with the first locking portion 11a on the panel side, and the second locking portion 22a on the component side is engaged with the second locking portion 12a on the panel side, thereby joining the first formwork panel 11 and the second formwork panel 12, thereby assembling the formwork panels into a wall shape. In this way, instead of using crosspieces, a joining member 20 is used, and the first member side engaging portion 21a and the second member side engaging portion 22a of the joining member 20 are engaged with the first panel side engaging portion 11a and the second panel side engaging portion 12a to join the first formwork panel 11 and the second formwork panel 12, thereby allowing the formwork panels to be assembled into a wall-like shape, which is easy to install and reduces waste material.

[0018] In this embodiment, as shown in Figure 2(d), one panel side ridge wall surface 11ax of the panel side ridge-shaped convex portion that forms the panel side first engagement portion 11a is a perpendicular surface to the first formwork panel outer surface 11s, the other panel side ridge wall surface 11ay of the panel side ridge-shaped convex portion is an inclined surface to the one panel side ridge wall surface 11ax, one panel side ridge wall surface 12ax of the panel side ridge-shaped convex portion that forms the panel side second engagement portion 12a is a perpendicular surface to the second formwork panel outer surface 12s, and the other panel side ridge wall surface 12ay of the panel side ridge-shaped convex portion is an inclined surface to the one panel side ridge wall surface 12ax. The member side groove-shaped recess that forms the member side first engagement portion 21a is formed with a vertical surface so that one member side groove wall surface 21ax abuts against one panel side ridge wall surface 11ax, and the other member side groove wall surface 21ay is formed with an inclined surface so that the other member side groove wall surface 21ay abuts against the other panel side ridge wall surface 11ay. In addition, the member side groove-shaped recess that forms the member side second engagement portion 22a is formed with a vertical surface so that one member side groove wall surface 22ax abuts against one panel side ridge wall surface 12ax, and the other member side groove wall surface 22ay is formed with an inclined surface so that it abuts against the other panel side ridge wall surface 12ay. Therefore, when the joining member 20 is engaged with the first formwork panel 11 and the second formwork panel 12, the first engaging portion 21a on the member side is such that the one member side groove wall surface 21ax abuts against the one panel side ridge wall surface 11ax and the other member side groove wall surface 21ay abuts against the other panel side ridge wall surface 11ay, and the second engaging portion 22a on the member side is such that the one member side groove wall surface 22ax abuts against the one panel side ridge wall surface 12ax and the other member side groove wall surface 22ay abuts against the other panel side ridge wall surface 12ay. In this way, the ridge wall surfaces 11ax, 12ax on one panel are perpendicular to the outer surfaces 11s, 12s of the formwork panels, and the ridge wall surfaces 11ay, 12ay on the other panel are inclined to the ridge wall surfaces 11ax, 12ax on the one panel, thereby ensuring reliable engagement and allowing engagement even if slight dimensional errors occur.

[0019] In the joining member 20 according to this embodiment, the first member-side locking portion 21a and the second member-side locking portion 22a are formed on the same plane. Therefore, by using the joining member 20, the first form panel 11 and the second form panel 12 are joined together so that the outer surface 11s of the first form panel and the outer surface 12s of the second form panel are flush with each other. In this way, by using the joining member 20, the first form panel 11 and the second form panel 12 that are arranged side by side on the same plane can be easily joined together.

[0020] In addition, the joining member 20 in this embodiment has a pipe recess 20c formed on the member side pipe abutment surface 20b adjacent to the member side panel abutment surface 20s where the member side first engaging portion 21a and the member side second engaging portion 22a are formed, for positioning the pipe material 6 to be attached to the outer surface of the form panel of the form panel 10. Therefore, after joining the first formwork panel 11 and the second formwork panel 12 using the joining member 20, the pipe material 6 can be placed in the pipe recess 20c, and the joining member 20 can also be used to install the pipe material 6 that supports the load applied to the formwork panel 10 when pouring concrete. Although the first formwork panel 11 and the second formwork panel 12 are described with different reference numerals, as is clear from the above description, they are panels with the same structure. The same applies to the following description.

[0021] FIG. 3 is a structural view showing another embodiment of a form panel and a joining member used in the form panel joining method according to the present invention. In the following description, the same components will be denoted by the same reference numerals and the description thereof will be omitted.

[0022] In FIG. 3(a), the panel-side first locking portion 11b formed on the first formwork panel 11 is formed as a panel-side groove-like recess, and the member-side first locking portion 21b is formed as a member-side ridge-like protrusion. In this embodiment shown in Figure 3(a), one panel side groove wall surface 11bx of the panel side groove-like recess that forms the panel side first engagement portion 11b is a perpendicular surface to the first formwork panel outer surface 11s, and the other panel side groove wall surface 11by of the panel side groove-like recess is an inclined surface with respect to the one panel side groove wall surface 11bx. In addition, in this embodiment, the member side ridge-shaped convex portion forming the member side first engagement portion 21b is formed as a vertical surface so that the one member side ridge wall surface 21bx abuts against the one panel side groove wall surface 11bx, and the other member side ridge wall surface 21by is formed as an inclined surface so that it abuts against the other panel side groove wall surface 11by. Therefore, when the joining member 20 is engaged with the first formwork panel 11 and the second formwork panel 12, the first engaging portion 21b on the member side abuts the one member side ridge wall surface 21bx against the one panel side gutter wall surface 11bx and the other member side ridge wall surface 21by against the other panel side gutter wall surface 11by, and the second engaging portion 22a on the member side abuts the one member side gutter wall surface 22ax against the one panel side ridge wall surface 12ax and the other member side gutter wall surface 22ay against the other panel side ridge wall surface 12ay.

[0023] In Figure 3(b), the panel side first engagement portion 11b formed on the first formwork panel 11 is formed as a panel side groove-shaped recess, the component side first engagement portion 21b is formed as a component side ridge-shaped protrusion, and the panel side second engagement portion 12b formed on the second formwork panel 12 is formed as a panel side groove-shaped recess, and the component side second engagement portion 22b is formed as a component side ridge-shaped protrusion. In this embodiment shown in Figure 3(b), one panel gutter wall surface 11bx of the panel gutter-like recess that forms the panel side first engagement portion 11b is a perpendicular surface to the first formwork panel outer surface 11s, and the other panel gutter wall surface 11by of the panel gutter-like recess is an inclined surface relative to the one panel gutter wall surface 11bx, and one panel gutter wall surface 12bx of the panel gutter-like recess that forms the panel side second engagement portion 12b is a perpendicular surface to the second formwork panel outer surface 12s, and the other panel gutter wall surface 12by of the panel gutter-like recess is an inclined surface relative to the one panel gutter wall surface 12bx.

[0024] In addition, in this embodiment, the member side ridge-shaped convex portion forming the member side first engagement portion 21b is formed as a vertical surface so that the one member side ridge wall surface 21bx abuts against the one panel side groove wall surface 11bx, and the other member side ridge wall surface 21by is formed as an inclined surface so that it abuts against the other panel side groove wall surface 11by. In addition, in this embodiment, the member side ridge-shaped convex portion forming the member side second engagement portion 22b is formed as a vertical surface so that the one member side ridge wall surface 22bx abuts against the one panel side groove wall surface 12bx, and the other member side ridge wall surface 22by is formed as an inclined surface so that it abuts against the other panel side groove wall surface 12by. Therefore, when the joining member 20 is engaged with the first formwork panel 11 and the second formwork panel 12, the first member side engaging portion 21b abuts the one member side ridge wall surface 21bx against the one panel side gutter wall surface 11bx and the other member side ridge wall surface 21by against the other panel side gutter wall surface 11by, and the one member side second engaging portion 22b abuts the one member side ridge wall surface 22bx against the one panel side gutter wall surface 12bx and the other member side ridge wall surface 22by against the other panel side gutter wall surface 12by.

The joining member 20 has a first member-side locking portion 21e that engages with the first panel-side locking portion 11f, and a second member-side locking portion 22e that engages with the second panel-side locking portion 12f. The first member-side locking portion 21e and the second member-side locking portion 22e are formed by a member-side ridge-like convex portion. As shown in Figures 18(c) and 18(d), the first member side locking portion 21e is engaged with the first panel side locking portion 11f, and the second member side locking portion 22e is engaged with the second panel side locking portion 12f, thereby joining the first formwork panel 11 and the second formwork panel 12, thereby assembling the formwork panels into a wall shape. In this way, instead of using crosspieces, a joining member 20 is used, and the first member side locking portion 21e and the second member side locking portion 22e of the joining member 20 are engaged with the first panel side locking portion 11f and the second panel side locking portion 12f to join the first formwork panel 11 and the second formwork panel 12, thereby allowing the formwork panels to be assembled into a wall-like shape, which is easy to install and reduces waste material.

[0068] In this embodiment, as shown in Figure 18(d), one panel side groove wall surface 11fx of the panel side groove-like recess that forms the panel side first engagement portion 11f is an inclined surface relative to the first formwork panel outer surface 11s, and the other panel side groove wall surface 11fy of the panel side groove-like recess is an inclined surface relative to the first formwork panel outer surface 11s, and the panel side groove-like recess is formed so that the bottom surface is wider than the opening surface.

Also, as shown in Figure 18(c), the member side ridge-shaped convex portion forming the member side first engagement portion 21e is formed with an inclined surface so that one member side ridge wall surface 21ex abuts against one panel side groove wall surface 11fx, and the other member side ridge wall surface 21ey abuts against the other panel side groove wall surface 11fy. In addition, the member side ridge-shaped convex portion forming the member side second engagement portion 22e is formed with an inclined surface so that one member side ridge wall surface 22ex abuts against one panel side groove wall surface 12fx, and the other member side ridge wall surface 22ey abuts against the other panel side groove wall surface 12fy. Therefore, when the joining member 20 is engaged with the first formwork panel 11 and the second formwork panel 12, the first member-side engaging portion 21e has one member-side ridge wall surface 21ex abutting against one panel's side gutter wall surface 11fx and the other member-side ridge wall surface 21ey abutting against the other panel's side gutter wall surface 11fy, and the one member-side second engaging portion 22e has one member-side ridge wall surface 22ex abutting against one panel's side gutter wall surface 12fx and the other member-side ridge wall surface 22ey abutting against the other panel's side gutter wall surface 12fy.

[0069] In the joining member 20 according to this embodiment, the first member-side locking portion 21e and the second member-side locking portion 22e are formed on the same plane. Therefore, by using the joining member 20, the first form panel 11 and the second form panel 12 are joined together so that the outer surface 11s of the first form panel and the outer surface 12s of the second form panel are flush with each other. In this way, by using the joining member 20, the first form panel 11 and the second form panel 12 that are arranged side by side on the same plane can be easily joined together.

The one-side joining member 20L and the other-side joining member 20R are configured with groove-like recesses 21r and ridge-like protrusions 21h arranged side by side. The groove-like recesses 21r and ridge-like protrusions 21h have the same length, and the groove-like recesses 21r and ridge-like protrusions 21h forming the one-side joining member 20L have the same shapes as the groove-like recesses 21r and ridge-like protrusions 21h forming the other-side joining member 20R. That is, the one-side joint member 20L and the other-side joint member 20R are the same member. In this way, by engaging the one-side joining member locking portion 21L with the other-side joining member locking portion 21R, the one-side joining member 20L and the other-side joining member 20R are connected, the member-side first locking portion 21e is engaged with the panel-side first locking portion 11f, and the member-side second locking portion 22e is engaged with the panel-side second locking portion 12f, and the first formwork panel 11 and the second formwork panel 12 are joined in a state in which the one-side joining member 20L and the other-side joining member 20R are connected.
