Description

[Technical field]

[0001] The present invention relates to the technical field of door frames installed at the entrances of buildings such as buildings and houses, and methods of filling door frames with filler material. [Background technology]

[0002] Generally, when a door body (door body, gate body) is provided at the entrance of a building such as a building or a house, a door frame in which the door body is provided so as to be freely opened and closed is erected on the inside surface (inner peripheral surface) of the opening on the body side that forms the entrance, and as such a door frame, a four-sided frame structure is adopted, which is assembled by connecting and fixing left and right vertical frame members and upper and lower horizontal frame members at connecting corners. When forming such a door frame, the frame material may be a flat metal plate material such as steel or stainless steel, which is bent into a cross section roughly in the shape of a letter U with an opening on the outer periphery side of the frame, and when a door frame using such a bent frame material is erected at the entrance, the opening on the outer periphery side of the frame of the frame material becomes hollow, with the opening on the outer periphery side covered by the inner periphery side of the body. When considering such a door frame, for example, in the case of a lower horizontal frame member that serves as a door sill, when people, luggage, or other currency passes through, the currency passes directly over the door sill, but there is a problem in that the passing sound generated at this time, for example, the sound of shoes made when a person passes through, becomes an amplified reverberation inside the hollow door sill and is emitted.To date, in order to deal with this problem, attempts have been made to fill the door sill with a filler made of a hardening substance with fluidity such as mortar or gypsum (for example, see Patent Document 1).

[0003] [Patent Document 1] JP 2018-145645 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when assembling a door frame, if the filler is filled into the door sill after the door frame is assembled, the assembled door frame must be turned upside down, the filler must be filled into the door sill, and the filler must be left in that upside-down position until it hardens, which results in problems such as poor workability, and these are the issues that the present invention aims to solve.

Effect of the Invention

[0006] By adopting the invention of claim 1, the flow-stopping material for the filler can have a simple structure comprising a flow-stopping surface portion that divides the hollow portion to prevent the filler from flowing toward the connecting corner portion, and an opposing piece portion that is bent relative to the flow-stopping surface portion and faces the inner surface portion of the hollow portion.Moreover, the flow-stopping material only needs to be temporarily held in place by the opposing piece portion in the frame material, which makes it easier to incorporate the flow-stopping material into the frame material, improving the workability of filling the filler and also of assembling the door frame. Furthermore, the temporary holding of the flow-stopping material to the frame material is achieved by the elastic restoring force that causes the opposing piece to abut against the inner surface in an elastically deformed state, as the bending angle of the opposing piece relative to the flow-stopping surface portion is made greater than the angle between the flow-stopping surface portion and the inner surface portion, and the flow-stopping material can be temporarily held in place in conjunction with its incorporation into the frame material, improving workability. By adopting the invention of claim 2, The flow-stopping material for the filler may be of a simple structure having a flow-stopping surface portion that divides the hollow portion to prevent the filler from flowing toward the connecting corner portion, and an opposing piece portion that is bent relative to the flow-stopping surface portion to face the inner surface portion of the hollow portion, and further, since the flow-stopping material only needs to temporarily hold the opposing piece portion to the frame material, it is easy to incorporate the flow-stopping material into the frame material, improving the workability of filling the filler and further the work of assembling the door frame. Furthermore, as a result of the temporarily held opposing piece being bent towards the side where the filling material of the hollow portion is to be filled, the opposing piece is supported by the filling material to be filled, thereby ensuring reliable holding of the flow-stopping material using the filling material. By adopting the invention of claim 3, The flow-stopping material for the filler may be of a simple structure having a flow-stopping surface portion that divides the hollow portion to prevent the filler from flowing toward the connecting corner portion, and an opposing piece portion that is bent relative to the flow-stopping surface portion to face the inner surface portion of the hollow portion, and further, since the flow-stopping material only needs to temporarily hold the opposing piece portion to the frame material, it is easy to incorporate the flow-stopping material into the frame material, improving the workability of filling the filler and further the work of assembling the door frame. Furthermore, when the flow-stopping material is bent, it can be bent while being guided by the guiding means, so that bending work can be easily performed with high accuracy. By adopting the invention of claim 4, The flow-stopping material for the filler may be of a simple structure having a flow-stopping surface portion that divides the hollow portion to prevent the filler from flowing toward the connecting corner portion, and an opposing piece portion that is bent relative to the flow-stopping surface portion to face the inner surface portion of the hollow portion, and further, since the flow-stopping material only needs to temporarily hold the opposing piece portion to the frame material, it is easy to incorporate the flow-stopping material into the frame material, improving the workability of filling the filler and further the work of assembling the door frame. Furthermore, the flow-stopping surface portion divides the hollow portion at an angle, positioned laterally inward from the edge portion of the frame material, and brings the filling area for the filler closer to the connecting corner portion. As a result, the flow of the filler into the connecting corner portion can be prevented while keeping the filling area for the filler as wide as possible. Claim 5 By using this invention, the flow-stopping material can be temporarily held in place on the frame material by adhering it to the inner surface portion of the opposing piece, improving workability. By adopting the invention of claim 6, the flow-stopping surface portion is positioned on the inside in the left-right direction of the end edge portion of the frame material, dividing the hollow portion at a right angle, thereby reliably preventing the filling material from flowing into the connecting corner portion. Claim 7 By using this invention, it is possible to easily create a door frame equipped with a door sill that prevents echoes of passing sounds, by using the frame material filled with the filling material as at least the lower horizontal frame material that serves as the door sill. Claim 8 By making this invention, the frame material for a door frame filled with filling material can be easily manufactured by carrying out the steps of a bending process of bending the opposing pieces of the flat flow-stopping material, an assembly process of incorporating the flow-stopping material into the hollow portion with the opposing pieces facing the inner surface portion, a temporary holding process of temporarily holding the opposing pieces of the flow-stopping material to the frame material, and a filling process of filling the hollow portion with filling material while the flow-stopping material is temporarily held. Claim 9 By using this invention, when assembling a door frame having a hollow portion of at least one of the four frame materials that make up the door frame, the frame material to be filled with the filler is filled with the filler in a state in which a flow-stopping material is provided in the hollow portion to stop the filler from flowing toward the left and right connecting corner portions, and the door frame is assembled using the frame material filled with the filler.As a result, it is no longer necessary to fill the filler with the frame material to be filled with the filler among the four assembled door frame while facing the ceiling surface, thereby improving workability. Moreover, The flow-stopping material for the filler may be of a simple structure comprising a flow-stopping surface portion that divides the hollow portion to prevent the filler from flowing toward the connecting corner portion, and an opposing piece portion that is bent relative to the flow-stopping surface portion and faces the inner surface portion of the hollow portion.The temporarily held opposing piece portion is bent toward the side of the hollow portion where the filler is to be filled, so that the opposing piece portion is supported by the filler material to be filled, thereby securely holding the flow-stopping material using the filler material and making it easy to assemble the door frame filled with the filler material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a door body, which is attached to a door frame 3 to which the present invention is applied via a support member such as a hinge (not shown) so as to be able to swing open and close, as in the conventional case. Although the door body 1 in this embodiment is of the hinged door type, it may be of the left-right sliding door type, and it goes without saying that the present invention can be similarly implemented with a door frame of such a sliding door type door body.

[0009] The door frame 3 is formed into a four-sided frame shape using left and right vertical frame members 4 and 5, which form the door end side (hanging side), and the door front side, an upper horizontal frame member 6, and a lower horizontal frame member 7, and is incorporated into the inside surface of the entrance E. In this embodiment, the present invention is embodied in the lower horizontal frame member 7, which is the threshold 7, of these frame members 4 to 7, and therefore, from here on, the threshold 7 will be described in detail and the other frame members 4 to 6 will be explained only as necessary. As mentioned above, the present invention has been implemented in the lower horizontal frame material, the door sill 7, but it is not limited to this and it goes without saying that it can be implemented in at least one of the required frame materials among the four frame materials 4 to 7 including the remaining frame materials 4 to 6.

[0010] The door sill 7 is made by bending a flat steel plate material into a cross section that is roughly U-shaped with an opening on the outer periphery side (lower surface side) of the door frame 3. More specifically, the door sill 7 is formed with two upper and lower steps, one for the indoor side, 7a and 7b, in which the indoor side, which is one side in the front-to-rear direction, is raised in a stepped manner, an indoor side vertical surface portion 7c that hangs down from the indoor side edge of the indoor side upper surface portion 7a, an outdoor side vertical surface portion 7d that hangs down from the outdoor side edge of the outdoor side upper surface portion 7b, and a bottom surface portion 7e that is bent from the lower edge of the outdoor side vertical surface portion 7d toward the indoor side. The space between the indoor side edge 7f of the bottom surface portion 7e and the lower edge 7g of the indoor side vertical surface portion 7c forms an opening Z, so that, as described above, the lower side, which is the outer periphery of the frame, is open and has a roughly U-shaped cross section, and has a hollow portion X surrounded on three sides by the upper surface portions 7a, 7b and the front and rear vertical surface portions 7c, 7d.When the doorway sill 7 is erected at the entrance / exit E, the opening Z of the doorway sill 7 is covered by the ground (floor) member on the structural body side. In addition, in this embodiment, the door sill 7 is configured to include, in addition to each of the surface portions 7a to 7e, a protruding surface portion 7h which is bent back from the outdoor side edge portion of the indoor side upper surface portion 7a toward the indoor side and whose tip edge protrudes to form a doorstop, and an intermediate vertical surface portion 7i which connects the indoor side edge portion of the protruding surface portion 7h with the indoor side edge portion of the outdoor side upper surface portion 7b.

[0011] The left and right end edges of the door sill 7 formed as described above are connected to the lower end edges of the left and right vertical frame members 4, 5 as connecting corners Y, and in this embodiment, the left and right vertical frame members 4, 5 are also bent into a roughly U-shaped cross section with a hollow portion by opening the outer periphery of the frame, just like the door sill 7, so that when they are erected at the entrance E, the opening side becomes covered and hollow, and the present invention can be implemented, if necessary, with such left and right vertical frame members 4, 5 as described above. Of course, the present invention can be implemented in the same manner with the upper horizontal frame member 6 if such a hollow portion is formed.

[0012] The vertical frame members 4, 5 also have stepped portions formed therein in order to form doorstops, and the vertical frame members 4, 5 and the shoe sill 7 are connected and fixed at the connecting corner portion Y. In this embodiment, locking portions 7j are formed to protrude from both left and right end edges of the indoor and exterior upper surface portions 7a, 7b. The left and right end edges of the shoe sill 7 are abutted against the lower end edges of the vertical frame members 4, 5 with the locking portions 7j penetrating through the through holes 4a, 5a formed in the vertical frame members 4, 5, and the penetrating locking portions 7j are bent, so that the shoe sill 7 is connected to the lower end edges of the vertical frame members 4, 5 in a non-slip manner. The opposing portions of the shoe sill 7 and the vertical frame members 4, 5, including the locking portions 7j, are appropriately welded together, so that the shoe sill 7 and the vertical frame members 4, 5 are connected and fixed integrally at the connecting corner portion Y. Incidentally, in the connecting corner portion Y, the abutment portion (butt joint portion) between the floor sill 7 and the vertical frame members 4, 5, and the through holes 4a, 5a through which the engaging portion 7j passes are sealed with sealing material (caulking material) K to prevent water such as rainwater from penetrating inside. In addition, the shoe sill 7 in this embodiment is reinforced by having a plurality of reinforcing surface portions 7k that connect the bottom surface portion 7e and the indoor side vertical surface portion 7c at appropriate intervals in the left-right direction, and by further providing reinforcing rods 7l that connect the reinforcing surface portions 7k.

[0013] In this embodiment, the floor sill 7 is filled with filler 8, which is mainly composed of a component that becomes fluid when water (hardening liquid) is supplied to it and kneaded, like gypsum or mortar, and hardens over time by hydration or polymerization (chemical reaction), and which may also contain auxiliary materials such as aggregates such as sand or pebbles, hardeners, and reaction accelerators, as necessary. In order to fill such filler 8 into the shoe sill 7, a flow-stop material 9 is used.

[0014] The flow-stopping material 9 used in this embodiment has approximately the same cross-sectional shape as the hollow portion X provided in the shoe sill 7, and is located in the inner left-right area close to the left and right edges of the shoe sill 7. It has a flow-stopping piece 9a that divides the hollow portion X at an angle to the left and right to prevent the pre-hardened filler material 8 from flowing into the connecting corner portion Y, and an opposing piece 9b that is bent at an obtuse angle relative to the flow-stopping piece 9a and faces the inner surface of the indoor side vertical surface portion 7c of the shoe sill 7 in a state of being close to or abutting the inner surface portion. It has an L-shape in a plan view, but the bending direction of the opposing piece 9b is toward the inner left-right direction of the area divided by the flow-stopping piece 9a in the hollow portion X, that is, toward the side where the filler 8 is filled. Incidentally, the flow-stopping material 9 in this embodiment has an opposing piece 9b that faces the indoor side vertical surface portion 7c, but it may also be bent to face the outdoor side vertical surface portion 7d, or even be bent so as to face both side portions 7c, 7d.

[0015] The flow stopper 9 of this embodiment is formed with the flow stopper piece 9a and the opposing piece 9b in a flat plate shape, and is to be folded. The slit 9c is formed as a guide means for facilitating the folding and preventing the folding position from shifting. The slit 9c of this embodiment is a long hole formed in the vertical direction, but as a guide means using such a slit, it is possible to form holes of various shapes, such as a chain line shape having a plurality of holes 9d as shown in the embodiment shown in Figures 7(A) and (B) or a cutout 9e with both upper and lower ends open. Furthermore, the guide means is not limited to a slit (hole), and can be implemented as a variety of shapes, such as a thin-walled folding portion or an R-groove 9f as shown in Figure 7(C). The R-groove 9f has the advantage of being provided with a function of encouraging (guiding) the folding direction to be inside the groove, thereby avoiding mistakes in the folding direction.

[0016] The flow-stopping material 9 bent in this manner is then fitted to the left and right edge portions of the shoe sill 7 which is in an upside-down position, i.e., with the opening Z facing upwards. In this case, the flow-stopping material 9 is positioned so that the flow-stopping piece 9a is located on the inside in the left-right direction close to the left and right edges of the shoe sill 7, i.e., is located more inside than the left and right edges of the shoe sill 7, thereby dividing the hollow portion at an angle and preventing the filler 8 filled in the hollow portion X from flowing into the connecting corner portion Y. On the other hand, the bent opposing piece 9b is located close to or abutting against the inner surface of the indoor side vertical surface portion 7c, and the opposing piece 9b is attached (glued, adhered) to the inner surface of the indoor side vertical surface portion 7c with adhesive tape (adhesive tape) 10, thereby temporarily holding the flow-stopping material 9 to the shoe sill 7. Furthermore, the portion that separates the hollow portion X by the flow-stopping piece 9a of the flow-stopping material 9 is located inside the left and right edges of the shoe rail 7. The reason for this is that, as mentioned above, when sealing the connecting corner portion Y with the sealing material K, it is necessary to fill the sealing material K from the hollow portion X side, and a filling space S for this purpose is secured between the connecting corner portion Y and the flow-stopping piece 9a so that the sealing material K can be filled. Incidentally, the temporary holding of the opposing piece 9b to the indoor side vertical surface portion 7c may be achieved not only by using the adhesive tape (sticky tape) 10 but also by directly using an adhesive, or by using a double-sided adhesive (sticky) tape. In addition, the definition of "adhesion" in this invention is not limited to the narrow sense of "adhesion" in which adhesion is achieved by solidifying (curing) an adhesive, but also includes the broad sense of adhesion in which adhesion is maintained by the adhesion of an adhesive, that is, the concept of "adhesion by an adhesive."

[0017] The hollow portion X of the shoe sill 7 with the flow-stopping material 9 temporarily held in this manner is then filled with unhardened filler 8, and the filler 8 is left to cure (be left alone) until it hardens. The filled filler 8 is filled in a state that covers the opposing piece 9b, and as a result, the flow-stopping material 9 is securely held by the opposing piece 9b of the hardened filler 8, and will not come off. The door frame 3 is then assembled using the door sill 7 filled with the filler 8 in this manner.

[0018] In the present embodiment configured as described above, the door frame 3 supporting the door body 1 that opens and closes the entrance E is formed into a four-sided frame, and the hollow portion X formed in the door sill 7, which is the lower horizontal frame member, is filled with a filler 8 to provide an anti-resonance function for passing sounds. In this case, the hollow portion X is provided with a flow-stopping member 9 for stopping the flow of the filler 8 toward the connecting corner portion Y, the flow-stopping member 9 comprising a flow-stopping piece 9a that divides the hollow portion X and stops the flow of the filler 8 toward the connecting corner portion Y, and an opposing piece 9b that is bent from the flow-stopping piece 9a and faces the indoor side vertical surface portion 7c in a state of being close to or in contact with the indoor side vertical surface portion 7c. When the flow-stopping member 9 is assembled into the hollow portion X, the opposing piece 9b is supported by the indoor side vertical surface portion 7c via an adhesive tape 10, so that the flow-stopping member 9 is temporarily held in place while the filling operation of the filler 8 is performed. As a result, the flow-stopping material 9 may be a simple structure having a flow-stopping piece 9a and an opposing piece 9b, and moreover, the flow-stopping material 9 only needs to be temporarily held in place by the opposing piece 9b on the frame material. As a result, the flow-stopping material 9 can be easily incorporated into the door sill 7, improving the work of filling the filling material 8 and the work of assembling the door frame.

[0019] Furthermore, in this case, the flow-stopping material 9 can be temporarily fixed to the door sill 7 simply by adhering the opposing piece 9b to the opposing indoor side vertical surface portion 7c via adhesive tape 10, thereby improving workability. In this case, the opposing piece 9b is bent toward the side of the hollow portion X where the filler 8 is filled, that is, toward the inside in the left-right direction of the shoe slide 7, and is arranged in the hollow portion X where the filler 8 is filled. As a result, the opposing piece 9b is covered with the hardened filler 8, which has the advantage of securely holding the flow-stopping material 9 using the hardened filler 8. Moreover, the flow-stopping material 9 is folded by folding the opposing piece 9b against the flow-stopping piece 9a, and as a result of a slit 9c being formed at this folding portion, folding can be performed while being guided by the slit 9c, making it easy to perform a precise folding operation of the flow-stopping material 9 in which the folding is guided at a predetermined folding position. Incidentally, in the present embodiment, the flow-stopping material 9 is configured to be temporarily held alone by adhering the opposing piece 9b of the flow-stopping material 9 to the indoor side vertical surface portion 7c via adhesive tape 10, so the other pieces of the flow-stopping material 9, for example the intermediate vertical piece 9g opposing the intermediate vertical surface portion 7i and the outdoor side vertical piece 9h opposing the outdoor side vertical surface portion 7d, do not need to abut against the opposing surface portions 7i, 7d and may be closely opposed to each other. However, in this embodiment, one intermediate vertical piece 9g may abut and the other outdoor side vertical piece 9h may be closely opposed to each other, or vice versa.

[0020] In this case, in this embodiment, the flow-stopping piece 9a of the flow-stopping material 9 is positioned left-right inward from the edge portion of the door sill 7 and divides the hollow portion X at an angle, and the direction of this angled partition is along the arrangement positions of the left-right inner side portions 4b, 5b of the vertical frame members 4, 5. In other words, the left-right inner side portions 4b, 5b of the vertical frame members 4, 5 are bent in a stepped shape so that the outdoor side is positioned outward in the left-right direction, and the flow-stopping piece 9a is configured to partition in a direction along the left-right inner side portions 4b, 5b which are misaligned in the left-right direction due to being formed in a stepped shape, that is, in an inclined state that is biased outward in the left-right direction as it approaches the outdoor side.As a result, the filling area of ​​the filling material 8 can be made as wide as possible, which is thought to contribute to improving the effect of preventing the generation of reverberation, etc.

[0021] Incidentally, in the above embodiment, the flow stopper piece 9a divides the hollow portion X at an angle, but it can also be divided at a right angle as in the second embodiment shown in Figures 8 and 9. In this second embodiment, an auxiliary plate 11 is provided at the connecting corner Y where the door-end side vertical frame member 5 of the door-end sill 7 is connected, and the auxiliary plate 11 is provided to assist the connection (welding) between the door-end sill 7 and the door-end side vertical frame member 5, and the left-right inner edge 11a of the auxiliary plate 11 is provided at a right angle to the inner surface of the indoor side vertical surface portion 7c of the door-end sill 7. Therefore, the flow stopper 9 on that side divides the hollow portion X at a right angle along the left-right inner edge 11a, and the present invention can be implemented in this way as well. In this case, the flow stopper piece 9a of the flow stopper 9 is different in length because the one at the end of the door is perpendicular and the one at the front of the door is inclined to divide the hollow portion X. As a result, two types of flow stopper 9 with different lengths may be formed, but as shown in FIG. 7(D), if the slit 9c is formed in two (multiple) places corresponding to the inclined and right-angle specifications, the same shape of flat flow stopper 9 can be used for both the inclined and right-angle specifications, and the parts can be used interchangeably. Also, the facing piece 9b may be formed in two or more (multiple) places, and in this case, the temporary holding does not need to be performed by both facing pieces 9b, but may be performed by only one facing piece 9b. Furthermore, when forming a guide means for guiding bending in the flow-stopping material 9, if the guide means is a slit 9c as in the above embodiment, by providing multiple slits 9c in the left and right directions, it is not limited to both inclined and vertical installation as described above, but can also be used when it is desired to change the angle of inclination. Furthermore, if the shoe sill 7 has specifications that differ in the flow-stopping width in the front-to-rear direction in the hollow portion X, the flow-stopping material 9 can be bent at a portion that corresponds to the specifications, and in this case too, it is possible to share the same parts.

[0022] In this way, in the embodiment of the present invention, the floor mat 7 can be formed in a state in which the flow of the filler 8 toward the connecting corner portion Y is prevented by using the flow prevention material 9. In this case, the procedure is as follows: A bending process for bending the opposing piece portion 9b of the flow stopper 9 An assembly process of assembling the flow-stopping member 9 into the hollow portion X with the opposing piece portion 9b facing the indoor side vertical surface portion 7c. A temporary holding step of temporarily holding the facing piece 9b on the indoor side vertical surface 7c via an adhesive tape 10. A filling step of filling the hollow portion X with the filling material 8 while the flow-stopping material 9 is temporarily held As a result of carrying out the above, the door sill 7 filled with the filler 8 can be easily formed as a single unit, and the door frame 3 can be assembled using the door sill 7 formed as a single unit. After assembling the door frame 3, there is no need to fill the filler 8 into the door sill 7 while it is upside down, and the door frame 3 including the door sill 7 filled with the filler 8 can be easily assembled.

[0023] Of course, the present invention is not limited to the above-described embodiment, and the number of opposing pieces 9b provided on the flow-stopping material 9 is not limited to one, but may be multiple, and the temporary holding means for temporarily holding the opposing pieces 9b is not limited to adhesion, but may utilize the elastic restoring force of the flow-stopping material 9. In other words, as in the third embodiment shown in Figure 10(A), by making the bending angle α between the flow stopping piece 9a and the opposing piece 9b of the flow stopping material 9 larger than the angle β between the flow stopping piece 9a and the indoor side vertical surface portion 7c (α > β), when the flow stopping material 9 is incorporated into the hollow portion X, the opposing piece 9b will abut against the indoor side vertical surface portion 7c in an elastically deformed state.As a result, the flow stopping material 9 will abut against the indoor side vertical surface portion 7c in an elastically compressed manner due to the elastic restoring force of the opposing piece 9b, and will be temporarily held in place, and the present invention can also be implemented in this manner. In order to achieve such temporary retention by elastic restoring force, the flow stopper 9 must be supported by contact with at least two opposing surfaces on the door sill 7, and in the third embodiment, the opposing piece 9b is configured to contact the indoor side vertical surface 7c, and the middle vertical piece 9g of the flow stopper 9 facing the middle vertical surface 7i is configured to contact the middle vertical surface 7i, but the outdoor side vertical piece 9h of the flow stopper 9 may be configured to contact the outdoor side vertical surface 7d of the door sill 7. Furthermore, the flow stopper 9 may be configured to contact the outdoor side top surface 7b and bottom surface 7e that are opposed to each other vertically, and at least one of them may be formed as the opposing piece to achieve temporary retention by elastic restoring force as described above. Furthermore, in the case where two opposing pieces 9b are provided in the structure utilizing the elastic restoring force, as in the embodiment shown in Figure 10(B), in which the opposing pieces 9b are formed as a pair to face the indoor side vertical surface portion 7c and the outdoor side vertical surface portion 7d of the door sill 7, it is not necessary to increase the bending angle of both opposing pieces 9b as described above. By increasing the bending angle α of one of the opposing pieces 9b as described above, temporary holding can be achieved while being subjected to the elastic restoring force by both opposing pieces 9b.

[0024] Furthermore, the present invention is not limited to the shape of the shoe sill 7 (frame material) in the above embodiment, but can be applied to various shapes, and can be applied to the shoe sill 7 shown in Figures 11(A), (B), and (C) by using a flow stopper 9 of a corresponding shape. Incidentally, the shoe sill 7 in Figure 11(B) has an inclined opening Z, and when filling the filler into such a shoe sill 7, if it is simply turned upside down, the opening Z will be inclined and the filler may collapse and flow out, so it is preferable to fill the filler in an upside-down state with the shoe sill 7 set at an inclination so that the opening Z is horizontal.
