JP7421371B2 - Fixing structure and method for door frame and opening frame material - Google Patents

Description

The present invention relates to a structure and method for fixing a door frame and an opening frame member.

Generally, a door frame is fixed to a structure on the building frame side at a site, thereby forming an opening that can be opened and closed by a door. Moreover, a door frame is often fixed by welding an element (sometimes referred to as an anchor) provided on the back side of the door frame to a structure on the building frame side (Patent Document 1).

However, fixing the door frame by welding cannot be used at sites where hot work is not possible, and since welding requires skilled techniques, there is also a problem in securing construction engineers. Therefore, there is a need to fix the door frame to the structure of the building frame without using welding work.

Patent Document 2 discloses a frame fixing structure in which a steel plate frame is attached to an opening of a building body without welding work. Patent Documents 3 and 4 disclose means for adjusting the gap between a fitting frame and an opening frame using liners or spacers.

Here, for example, if the structure on the frame side to which the door frame is attached is tilted in the front-rear direction, there is a risk that the door frame attached to the structure will also tilt in the front-rear direction. It is necessary to adjust the posture (adjust the tilt or fall to make it vertical) and fix it.

It should be noted that the spacer 5 is not shown (this can be seen as a state before the spacer 5 is provided, or a case where no positional adjustment in the front-rear direction is required).

The door frame according to the present embodiment is a three-sided frame consisting of an upper frame 1 and left and right vertical frames 2, and the space surrounded by the door frame, which is the three-sided frame, and the floor surface FL serves as a building opening. The building opening is opened and closed by a door (not shown). Although the illustrated door frame is for a hinged door, the type of door is not limited.

A three-sided door frame is manufactured by fixing (welding) the upper ends of left and right metal (e.g., steel) vertical frames 2 to the longitudinal ends of metal (e.g., steel) upper frames 1 at the factory. , screws, etc.). That is, the door frame is assembled at a factory, transported to the site, and fixed to the frame structure. In this embodiment, the structure on the frame side is composed of an opening frame material 3, studs 4 to which the opening frame material 3 is fixed, and runners 4', and the door frame is attached to the opening frame material 3. It will be done. Note that the three-sided door frame is just an example, and the door frame may be a four-circumferential frame.

The structure of the door frame will be explained mainly based on the structure of the vertical frame 2. The left and right vertical frames 2 are long members extending in the height direction (vertical direction), and as shown in FIG. An inner prospecting portion 22 connecting the inner end of the surface 20 and the second finding surface 21 , a first outer prospecting side 23 extending in the prospecting direction from the outer end of the first finding surface 20 , and a second finding surface 21 . A second outer prospect side 24 extending from the outer end in the direction of prospect, a first outer prospect piece 25 extending outward from the tip of the first outer prospect side 23, and a second outer prospect side 24 extending outward from the tip of the second outer prospect side 24. It consists of an outer facing piece 26.

In the vertical frame 2, the first outside expected side 23 and the second outside expected side 24 are spaced apart, and there is a gap between the first outside expected side 23 and the second outside expected side 24 in the height direction of the vertical frame 2. A plurality of connecting elements 27 are fixed (welded, screwed, etc.) at intervals to improve the strength of the vertical frame 2. The inner prospecting section 22 includes a first inner prospecting surface 220 extending in the prospecting direction from the inner end of the first finding surface 20, and a second inner prospecting surface 221 extending in the prospecting direction from the inner end of the second finding surface 21. It consists of a convex central prospecting portion 222 located between a first inner prospecting surface 220 and a second inner prospecting surface 221 . The cross-sectional shape of the vertical frame 2 (in particular, the inner prospective portion 22) is not limited. On the first inner facing surface 220 of the vertical frame 2 on one side (on the door end side), a plurality of hinge elements H are provided at intervals in the height direction.

The first outer facing piece 25 and the second outer facing piece 26 are located on the back side of the vertical frame 2 and extend apart from each other, and in this embodiment, the first outer facing piece 25 is a long piece, The second outer facing piece 26 is a short piece. The first outer facing piece 25 and the second outer facing piece 26 constitute a mounting piece for attaching the vertical frame 2 to the structure on the frame side. It is fixed to the opening frame member 3 extending in the height direction via the second outer facing piece 26.

The upper frame 1 is a long member extending in the opening width direction (horizontal direction), and has the same cross-sectional shape as the vertical frame 2 in this embodiment. That is, the posture when the vertical frame 2 is oriented so that the inner facing part 22 is the lower surface, the first outer facing piece 25 and the second outer facing piece 26 are located on the upper side, facing apart and extending upward. The upper frame 1 can be explained according to the following.

More specifically, the upper frame 1 includes a first finding surface 10, a second finding surface 11, and an inner side connecting the inner ends (lower ends) of the first finding surface 10 and the second finding surface 11. The projection part (lower surface part) 12, the first outer (upper) projection side extending in the projection direction from the outer end (upper end) of the first projection surface 10, and the projection from the outer end (upper end) of the second projection surface 11. a second outer (upper) prospective side extending in the direction; a first outer (upper) facing piece 15 extending outward (upward) from the tip of the first outer prospective side; ), and a second outer (upper) indexing piece 16 extending to Note that, like the vertical frame 2, the cross-sectional shape of the upper frame 1 is not limited.

The first outer facing piece 15 and the second outer facing piece 16 are located on the back surface (above) of the upper frame 1 and extend apart from each other (see FIGS. 1, 2, 8, and 9). In this embodiment, the first outer facing piece 15 is a long piece, and the second outer facing piece 16 is a short piece. The first outer facing piece 15 and the second outer facing piece 16 constitute a mounting piece for the upper frame 1, and the upper frame 1 has the first outer facing piece 15 and the second outer facing piece 16. It is fixed to the opening frame member 3 extending in the width direction of the opening.

The first outer facing piece 25 of the vertical frame 2 of the door frame according to this embodiment is cut out at a plurality of locations at intervals in the height direction. More specifically, as shown in FIG. 1, the first outer facing pieces 25 of the left and right vertical frames 2 each have three cutout portions C1 at an upper portion, a lower portion, and an intermediate portion in the height direction. We are prepared. The notch C1 formed in the vertical frame 2 is a vertically long notch. These notches C1 function as spaces for inserting a spacer. Note that in this specification, the term "notch" defines the shape or configuration of an element, and is not necessarily limited to a shape obtained by cutting out a part of the element.

As shown in FIGS. 1 and 2, the second outer facing pieces 26 of the left and right vertical frames 2 are cut out corresponding to the notches C1 in the upper and lower parts of the opposing first outer facing pieces 25. A notch C2 is formed and communicates the first outer facing piece 25 and the second outer facing piece 26 of the vertical frame 2 in the direction of projection. This communication space functions as a wedge insertion portion K'. Note that the cutout portion C2 is an optional element, and the cutout portion C2 does not need to be provided. Depending on the manner in which the wedge is inserted, the wedge insertion portion may be formed only by the cutout portion C1.

Both the left and right ends of the first outer facing piece 15 in the length direction of the upper frame 1 are cut out to form cutout portions C3, and the left and right edges of the first outer facing piece 15 in the length direction are cut out. 150 and 151 are located inside the left and right edges of other parts of the upper frame 1. The notch C3 formed in the upper frame 1 is a horizontally long notch. These notches C3 function as spaces for inserting a spacer. Note that, similarly to the vertical frame 2, a notch portion may be formed so as to leave both ends in the length direction of the first outer facing piece 15 of the upper frame 1.

The frame-side structure according to the present embodiment includes an opening frame material (sometimes referred to as a reinforcing frame material) 3 to which the door frame is fixed, and a base frame material to which the opening frame material 3 is fixed. It is composed of and. The base frame material horizontally connects left and right studs 4 extending in the vertical direction, runners 4' that horizontally connects predetermined parts on the upper side of the left and right studs 4 in the height direction, and horizontally connects the lower end parts of the left and right studs 4. and a runner (not shown). Typically, the opening frame member 3, stud 4, and runner are made of metal (for example, steel).

The stud 4 is an elongated member that has a U-shape in cross section from a first found side 40, a second found side 41, and an expected side 42 (see FIG. 5(A)), and extends in the height direction, It is provided in a vertical position with the prospective side 42 positioned on the opening side. The runner 4' is an elongated member that has substantially the same cross-sectional shape as the stud 4 and extends in the horizontal direction, and is provided with its prospective side positioned on the opening side (lower side).

The opening frame member 3 is an elongated member having a U-shape in cross section including a first found side 30, a second found side 31, and an expected side 32 (see FIG. 5(A)). The opening frame material 3 is fixed to the stud 4 in a vertical position with the expected side 32 located on the opening side, and fixed to the runner 4' in a horizontal position with the expected side 32 located on the opening side (lower side). be done. More specifically, the bent pieces 300 and 310 are formed by bending the tips of the first facing side 30 and the second facing side 31 of the opening frame material 3 inward, and the opening frame material 3 is , the bent pieces 300, 310 are fixed in contact with the expected side 42 of the stud 4 and the expected side of the runner 4'. Welding is exemplified as a means for fixing the opening frame member 3. At the stage of attaching the opening frame material 3, there are no combustible materials on site that would cause problems with hot work, so no problems will occur due to the use of welding. Note that the opening frame member 3 may be fixed to the stud 4 and runner 4' using screws.

As shown in FIG. 5 etc., the estimated dimensions of the opening frame material 3 are slightly smaller than the estimated dimensions of the studs 4, and when the opening frame material 3 is fixed to the studs 4, the The first found side 30, the first found side 40 of the stud 4, the second found side 31 of the opening frame member 3, and the second found side 41 of the stud 4 are each stepped.

As described above, in this embodiment, the structure on the building frame side is composed of the opening frame material 3, the studs 4, and the runners 4', and the door frame (three-sided structure consisting of the upper frame 1 and the left and right vertical frames 2). The frame) is fixed after being positioned by adjusting the position relative to the structure on the frame side (opening frame material 3). This position adjustment includes position adjustment of the door frame relative to the opening frame member 3 in the facing direction. The position adjustment of the door frame in the facing direction is mainly the position adjustment in the X direction and the Z direction in FIGS. 4, 10, and 11.

Adjustment of the position of the door frame in the facing direction will be described with reference to FIGS. 10 and 11. 10 and 11 are diagrams exclusively for explaining the position adjustment of the door frame in the finding direction, and the door frame (upper frame 1', left and right vertical frames 2') and opening shown in FIGS. It should be noted that the fixing structure with the frame material 3 is different from the fixing structure of the door frame according to this embodiment. The dimensions of the vertical rectangular space surrounded by the opening frame material 3, which is the structure on the frame side, are slightly larger than the external dimensions of the door frame (upper frame 1', left and right vertical frames 2'), and The prospective surface on the back side (the first outer prospective side 23, the second outer prospective side 24) and the prospective side 32 of the opening frame member 3 are spaced apart from each other and face each other through a gap. By adjusting the dimensions of this gap (dimensions in the X direction, Z direction), the position of the door frame relative to the opening frame member 3 in the facing direction is adjusted. Note that the approximate position of the door frame relative to the opening frame member 3 in the expected direction (Y direction) may be adjusted.

As a specific adjustment method, a method using a so-called wedge K can be exemplified. Insert a wedge K with a right-angled triangular cross-sectional view into the gap from the first and second sides in the perspective direction, and combine the two wedges K so that their sloped surfaces overlap (wedge set), depending on the degree of overlap of the sloped surfaces. The thickness of the wedge set is variable, and the gap between the door frame and the opening frame material is determined by the thickness of the wedge set. The illustrated wedge K is an example, and the shape of the wedge is not limited to a right triangle in cross section, and the number of wedges inserted into the gap is not limited either, and may be one or three or more.

In the example shown in FIG. 10, wedge sets are provided at both left and right end portions of the upper frame 1', at the upper and lower portions of the left and right vertical frames 2', and at the lower ends of the left and right vertical frames 2', so that the expected direction of the door frame is While adjusting the position of the door frame, temporarily fix the position of the door frame (position in the X direction and position in the Z direction). After the temporarily fixed door frame is fixed to the opening frame material 3 using a plurality of wedge sets, the wedges K are removed.

In this embodiment as well, wedge insertion portions K' into which wedges are inserted are formed at both left and right end portions of the upper frame 1 and at upper and lower portions of the left and right vertical frames 2 (Figs. 1 to 3). ), the position of the door frame can be adjusted using a wedge. More specifically, the cutout portions C1 and C2 of the upper portion passing through the upper portion and the lower portion of the first outer facing piece 25 and the second outer facing piece 26 of the left and right vertical frame 2 in the projection direction, and the lower part The cutout portions C1 and C2 of the portion form a wedge insertion portion. Further, a wedge insertion portion K' is formed outside the left and right end portions of the upper frame 1 and above the upper end portions of the left and right vertical frames 2.

Here, the position adjustment of the door frame is not limited to position adjustment in the facing direction. For example, the opening frame member 3, which is a frame-side structure to which a door frame is attached, is not necessarily in a strictly vertical position. For example, if the opening frame material 3 is slightly tilted in the front-rear direction (the direction of entry and exit of the opening, that is, the Y direction) (see FIGS. 8 and 9), the door frame attached to the opening frame material 3 There is also a risk that it will tilt forward and backward. The present embodiment provides a fixing structure for a door frame and an opening frame member that allows the posture of the door frame to be adjusted (adjusting the inclination or inclination to a vertical posture) when necessary.

The structure and method for fixing the door frame and the opening frame member 3 according to the present embodiment will be described based on the structure and method for fixing the vertical frame 2 and the opening frame member 3. A three-sided frame consisting of an upper frame 1 and left and right vertical frames 2 is assembled at a factory and transported to the site. The structure on the frame side at the site consists of a base frame consisting of a runner 4' that connects the studs 4 on the left side and the studs 4 on the right side, and a three-sided opening frame member 3 fixed to the base frame. . The door frame is attached to the opening frame member 3.

On the back side of the vertical frame 2 of the door frame, a first outer facing piece 25 and a second outer facing piece 26 extend in a spaced-apart manner and face each other. The first outer facing piece 25 is longer than the second outer facing piece 26. That is, the first outer facing piece 25 is a long piece, and the second outer facing piece 26 is a short piece. The dimension between the inner surface of the first outer facing piece 25 and the inner face of the second outer facing piece 26 of the door frame is the estimated dimension of the opening frame material 3 (the outer surface of the first facing side 30 and the second facing side 31).

In this embodiment, by making the second outer facing piece 26 of the vertical frame 2 shorter than the first outer facing piece 25, the second outer facing piece 26 does not get in the way, and the first outer facing piece It is possible to make the facing piece 25 face the first facing side 30 of the opening frame member 3 from the front and fix it with the screw S1 (FIGS. 5A and 5B). As shown in FIG. 5(B), when the first outer facing piece 25 is fixed to the first facing side 30 with the screw S1, the tip of the second outer facing piece 26 of the vertical frame 2 is connected to the opening. It is spaced apart from the frame member 3 (the corner formed by the second facing side 31 and the facing side 32).

In one aspect, when the screw S1 is tightened and the first outer facing piece 25 is brought into contact with the first facing side 30 (in the case where the spacer 5 is not provided), the second outer facing of the vertical frame 2 The outer surface of the attaching piece 26 and the outer surface of the second facing side 31 of the opening frame member 3 are designed to be substantially flush with each other. Therefore, in the height direction of the vertical frame 2, in places where positional adjustment in the front-rear direction (Y direction) is not required, it is necessary to straddle the second facing side 31 and the outer surface of the second outer facing piece 26, which are flush with each other. The connecting member 6 made of a metal plate is brought into contact with the connecting member 6, the connecting member 6 and the second facing side 31 are connected with the screw S2, and the connecting member 6 and the second outer facing piece 26 are connected with the screw S3. It should be noted that FIG. 5C shows a mode in which the spacer 5 is inserted between the first outer facing pieces 25 and the first facing sides 30.

Position adjustment of the vertical frame 2 in the expected direction (Y direction) with respect to the opening frame material 3 will be explained. When fixing the first outer finder piece 25 to the first finder side 30 with the screw S1, if the position adjustment in the expected direction (Y direction) is required, the first outer finder piece 25 and the By inserting the spacer 5 between the vertical frame 2 and the attached side 30, the position of the vertical frame 2 in the expected direction or the front-back direction is adjusted. Insertion of the spacer 5 is performed with the first outer facing piece 25 fixed (temporarily fixed) to the first facing side 30 with the screw S1 (see FIG. 5(B)). As shown in FIG. 5(B), when the first outer finder piece 25 is fixed (temporarily fixed) to the first finder side 30 with the screw S1, the first outer finder piece 25 is adjacent to the outer side of the tip of the first outer finder piece 25. It should be noted that the stud 4 is positioned to form a stepped portion D (there is no space for inserting the spacer), and the spacer 5 cannot be inserted from the side.

As shown in FIG. 7, the spacer 5 is an elongated metal plate having a predetermined thickness, and extends in the lateral direction at one end in the longitudinal direction of one long side of the rectangular plate portion 50. A first locking groove 51 is formed, and a second locking groove 52 extending in the longitudinal direction is formed on the short side of the other end in the longitudinal direction. By providing the first locking groove 51 and the second locking groove 52 with different groove directions, by preparing one type of spacer 5, the insertion direction (vertical direction, horizontal direction) and insertion posture ( The first locking groove 51 or the second locking groove 52 can be selected depending on the vertical position or horizontal position, and can be locked to the shaft portion of the screw S1. In the illustrated embodiment, the longitudinal dimension of the spacer 5 is smaller than the height dimension of the notch C1. The spacer 5 shown in FIG. 7 is an example, and the shape of the spacer 5 is not limited to the illustrated embodiment. In adjusting the position of the vertical frame 2 in the front-rear direction, the spacers 5 may be provided one on top of the other, or a plurality of types of spacers with different thicknesses may be prepared.

As shown in FIGS. 1 and 3, a part of the screw S1 that fixes the first outer facing piece 25 of the vertical frame 2 to the first facing side 30 of the opening frame member 3 is connected to the first outer facing piece. The notch C1 is provided near the upper edge 250 and lower edge 251 of the cutout C1 formed in the cutout C1. Such a screw S1 will be referred to as a spacer locking screw. As shown in FIG. 3, spacer locking screws S1 are provided above the upper edge 250 and below the lower edge 251 of the notch C1, respectively. As is clear from FIG. 3, the vertical distance between the spacer locking screw S1 and the upper edge 250 and the vertical distance between the spacer locking screw S1 and the lower edge 251 are larger than the longitudinal dimension of the spacer 5. In the illustrated embodiment, the distance is approximately half the length of the spacer 5.
