  In the joinery frame described in Patent Document 1, the front frame and the rear frame are welded or joined to each other with bolts and nuts, then placed in the opening of the wall, and joined to the base curing material (column) through the connecting material. Therefore, as a mounting order, first, the front frame and the rear frame coupled to the pillar are joined via the connecting material, and then the wall board material (wall panel) is built.

  However, since the worker who builds the pillar and the worker who sticks the wall panel are often the same worker, first build the pillar that forms the opening, join the door frame to this pillar, and In the procedure of building a panel, the worker who built the pillar must wait until the door frame construction is completed.

  For example, if the installation work of the door frame is delayed or the number of door frames that need to be installed is large, the waiting period until the wall panel is pasted becomes long. Workers may enter work at other sites due to the longer waiting period, but if the work at other sites is delayed, the installation of the door frame is completed and the wall panel is installed. Even if it is waiting to be built, it will not be possible to exit from the other site, and it will not be possible to return to the site where the wall panel is pasted. Then, the process adjustment and management will be very difficult. Accordingly, there is a demand for a door frame having high workability that enables workers of different industries to perform work on a construction site in order without going back and forth.

  Then, an object of this invention is to provide the construction method of the door frame and the door frame which has the compatibility which can respond even if an error arises in the wall thickness of an opening part, and favorable workability | operativity.

  The door frame of the present invention includes a first frame provided at an opening edge on one wall surface side of the opening of the wall surface, and a second frame provided at an opening edge on the other wall surface side of the opening. The first frame body includes a door stop portion provided at the front end inside the opening, and an inner front end portion of the second frame body provided on the back side of the door stop portion and overlapping the door stop portion. A holding portion that is sandwiched together with the door stop portion from the back side is formed.

  Further, the door frame construction method of the present invention includes a first frame body provided at an opening edge portion on one wall surface side of the opening portion of the wall surface and an opening edge portion provided on the other wall surface side of the opening portion. A method of attaching a door frame comprising two frame bodies to the opening, wherein the door stop is provided at the front end inside the opening, provided on the back side of the door stop, and the door stop A step of disposing from the one wall surface side a first frame formed with a holding portion that sandwiches the inner end portion of the second frame overlapping with the door stop from the back side; and A step of fixing to the opening, and disposing the second frame body from the other wall surface side to the opening, and placing an inner front end portion of the second frame body between the door stop portion and the holding portion. Including a step of inserting and a step of fixing the second frame to the opening. To.

  The door frame of the present invention is formed of two frames, a first frame and a second frame. The first frame body is provided at an opening edge portion on one wall surface side of the opening portion of the wall surface. A 2nd frame is provided in the opening edge part of the other wall surface side of an opening part. When these two frames are installed in the opening, the first frame is fixed to the opening after the first frame is arranged from one wall surface side. Next, the second frame is arranged from the other wall surface side to the opening, and the inner front end portion of the second frame is inserted between the door stop provided at the front end of the opening and the holding portion. To do. The holding portion provided on the back side of the door stop portion sandwiches the inner front end portion of the second frame that overlaps with the door stop portion together with the door stop portion from the back side, so that the first before the door frame is installed in the opening portion. There is no need to connect the frame and the second frame. Therefore, the door frame can be constructed after the wall surface is formed. In addition, since the second frame body is only sandwiched between the door stop portion and the holding portion, even if the wall thickness becomes thicker or thinner due to the construction error of the opening portion, Only the degree of overlap with the inner tip portion of the frame changes. Therefore, it can be determined from the appearance that the degree of overlap is hidden behind the door stop, so that even if an error occurs in the wall thickness of the opening, it can be dealt with.

The first frame extends from one wall surface side of the wall panel to the inside of the opening, and a fixing space is formed between the inner side surface of the opening formed by the frame member and the back side surface of the first frame body. The second frame is formed in a substantially L-shape to be secured, and the second frame extends from the other wall surface side of the wall panel to the inside of the opening and can be inserted between the door stop portion and the holding portion. It is desirable to be formed in a shape.
The first frame is formed in a substantially L shape extending from one wall surface side to the inside of the opening by the wall surface panel, but between the frame member forming the opening and the back side surface of the first frame. Since the fixing space is secured, the first frame can be fixed to the frame member even after the wall panel forming the wall surface is built on the frame member forming the opening. And since the 2nd frame is formed in the substantially L shape extended from the other wall side to the opening part inner side, after fixing the 1st frame, the 2nd frame is changed from the other wall side. It can be inserted and fixed between the door stop portion of the one frame body and the holding portion.

  A first connecting member disposed on the back side of the first frame body, and a second connecting member disposed at a position of the frame member connectable to the first connecting member and connected to the frame member by a screw member Preferably, the first connecting member and the second connecting member are connected by a screw member in the fixed space. It can fix, without using welding by connecting a 1st frame and a frame member with a 1st connection member and a 2nd connection member.

  An S-shaped connecting member that is in contact with a back side surface of the first frame and a mounting surface of the frame member is provided in the fixed space, and the S-shaped connecting member is connected to the first frame. It is also possible to connect to the frame member by a screw member. It can fix without using welding by connecting a 1st frame and a frame member by a S-shaped connection member.

  A fixing jig for fixing the second frame body to the frame member is provided, and the fixing jig includes a cylindrical spacer member that secures a space between the second frame body and the frame member. It is desirable that a screw member inserted through the spacer member from the second frame body and screwed to the frame member is provided. Since a fixing space is secured in the first frame body, a space is formed between the second frame body and the frame member in a state where the second frame body is connected to the first frame body. Therefore, when the second frame is fixed to the frame member, the surface of the second frame may be recessed if it is simply fixed with a flat screw. Therefore, by using a fixing jig in which a screw member is inserted into a spacer member that secures a space between the second frame and the frame member and is screwed to the frame member, the space between the second frame and the frame member is used. The second frame can be fixed to the frame member in a state in which the space is secured.

  When the first frame body and / or the second frame body are formed so that the connection between the vertical frame portion and the horizontal frame portion is separable, the first frame body and / or the second frame body respectively. Since the vertical frame portion and the horizontal frame portion can be stored in a separated state or can be carried into the construction site, a large storage place is not required and transportation is easy.

  According to the structure of this invention, since the inner side front-end | tip part of the 2nd frame which overlaps with a door stop part is inserted | pinched with a door stop part from the back side, construction of a door frame is possible after a wall surface is made. Further, according to the configuration of the present invention, even if an error occurs in the wall thickness, it can not be determined from the appearance that the degree of overlap is hidden behind the door stop, so even if an error occurs in the wall thickness of the opening. Can respond. Therefore, the present invention can have both the compatibility that can cope with an error in the wall thickness of the opening and the good workability.

Then, in a state where the opposing surfaces of the U-shaped plate 141 and the L-shaped plate 142 are abutted with each other, the screw member N2 is inserted from the L-shaped plate 142 side and is screwed, so that the column member Kx and the first frame 111 and Is fixed.

  In the present embodiment, the U-shaped plate 141 is used to connect the first frame body 111 and the column member Kx at the position where the hinge H is provided. 131 and hook plate 132 may be connected.

  As shown in FIGS. 2 and 3, the second frame bodies 112 and 122 are provided at the opening edge of the opening K on the other wall surface S <b> 2 side. The second frames 112 and 122 have a generally L-shaped cross section as a whole. Specifically, the second frame bodies 112 and 122 extend from the other wall surface S2 side of the wall panel P to the inside of the opening, and are inserted between the door stop portions 111a and 121a and the holding portions 111b and 121b.

  Here, a fixing jig for fixing the second frames 112 and 122 to the column member Kx and the beam member Ky will be described with reference to FIG. FIG. 6 shows a state in which the horizontal frame portion 12 is fixed to the beam member Ky, and a state in which the vertical frame portion 11 is fixed to the column member Kx indicates that the beam member Ky is fixed to the column member Kx. Instead, the second frame 122 of the horizontal frame portion 12 is simply replaced with the second frame 112 of the vertical frame portion 11 and is omitted.

  As shown in FIG. 6, the second frame 122 is fixed to the beam member Ky by the fixing jig 15. The fixing jig 15 includes a cylindrical spacer member 151 for securing a gap (space) between the second frame body 122 communicating with the fixing space R and the beam member Ky, and a spacer member from the second frame body 122. 151, and a screw member 152 that is inserted through 151 and screwed to the beam member Ky. The spacer member 151 is welded to the back side surface of the second frame body 122. The second frame body 122 is provided with a through hole communicating with the hole of the spacer member 151 so that the position of the spacer member 151 can be visually recognized from the front surface side.

  The door frame 1 according to the present embodiment is not only divided into two parts in the front-rear direction, but also a vertical frame part 11 and a horizontal frame part 12 are formed so as to be separable. That is, the door frame 1 is divided into six parts. As shown in FIGS. 7A and 7B, the first frame body 111 of the vertical frame portion 11 will be described as an example. The first frame body 111 has L formed with through holes at both ends. A connecting member 16 in which a nut 162 is welded with a hole position aligned is provided on the bracket 161. The first frame bodies 111 and 111 of the two vertical frame portions 11 and the horizontal frame are secured to the connecting member 16 by screwing the end portions of the first frame body 121 of the horizontal frame portion 12 (not shown) at right angles. The first frame 121 of the part 12 can be connected.

The construction method of the door frame 1 which concerns on embodiment of this invention comprised as mentioned above is demonstrated based on drawing.
In the opening K to which the door frame 1 is attached, the column member Kx is already erected together with the reinforcing member Kz, the beam member Ky is installed between the column members Kx, and the wall panel P is pasted so as to cover them. The U-shaped plate 141 is attached together with the hinge H.

  First, the hook plates 132 are attached at equal intervals at three positions between the L-shaped plates 142 of the column members Kx. A hook plate 132 is also attached to the central portion of the beam member Ky. At this time, the hook plate 132 is attached only by lightly tightening the screw through the long hole 132b, and the screw is not attached to the round hole 132c. That is, the hook plate 132 is temporarily fixed.

(Attaching the first frame)
Next, the first frame bodies 111 and 121 that are connected and divided into three-way frames are arranged in the opening K from the one wall surface S1 side. When the first frames 111 and 121 are disposed, after the first frames 111 and 121 are advanced to the position where the locking member 131 is in front of the hook plate 132, the column members Kx or the beam member Ky side Retreat while pressing against. By doing so, the locking member 131 is hooked on the hook portion 132 a of the hook plate 132. In this state, the position of the hook plate 132 is adjusted to screw a screw into the round hole 132c, and the screw attached to the long hole 132b is screwed to permanently fix the hook plate 132.

  At this time, the opening between the first frame bodies 111 and 121 is measured, and it is confirmed whether or not a width capable of attaching the hinged door 2 is secured. If the width is too wide, the first frame 111, 121 is moved and adjusted. Since the locking member 131 and the hook plate 132 are not fixed, the first frame bodies 111 and 121 can be moved and adjusted by moving the locking member 131 while sliding on the hook plate 132. . Therefore, even if the design value and the actual state are slightly different, they can be adjusted by adjusting the interval between the first frames 111.

Next, according to the position of the U-shaped plate 141 attached to the first frame 111 together with the hinge H, the L-shaped plate 142 is screwed to the column member Kx, and the U-shaped plate 141 and the L-shaped plate 142 are attached. Screwed with the screw member N2. Thus, the first frame body 111 is fixed to the column member Kx, and the first frame body 121 is fixed to the beam member Ky.
Thus, even if the wall surface panel P is affixed to the column member Kx and the beam member Ky, the first frame 111, the column member Kx, and the first frame 121 are utilized using the fixing space R. Since the beam member Ky can be connected, the first frames 111 and 121 can be attached to the opening K.

(Attaching the second frame)
The connected second frame bodies 112 and 122 in a three-way frame state are arranged in the opening K from the other wall surface S2 side. When the second frames 112 and 122 are arranged, the second frames 112 and 122 are inserted into the gaps between the door stop portions 111a and 121a of the first frames 111 and 121 and the holding portions 111b and 121b. While inserting the inner tip.

  Next, the screw member 152 is inserted into the through hole provided in accordance with the position of the spacer member 151 provided on the back side surface of the second frames 112 and 122, and the column member Kx and the beam member Ky are inserted through the spacer member 151. And screw in. Even if a space communicating with the fixing space R is secured between the second frame bodies 112 and 122 and the column member Kx and the beam member Ky, the spacer member 151 supports the gap, so that the screw member 152 is strengthened. Even if it is screwed in, there is no dent due to the pressing of the head of the screw member 152 on the front surface of the second frame bodies 112, 122.

  As described above, the holding portions 111b and 121b provided on the back sides of the door stop portions 111a and 121a are arranged so that the inner front end portions of the second frames 112 and 122 that overlap the door stop portions 111a and 121a from the back side to the door stop portions 111a and 111a, Since it is inserted together with 121a, it is not necessary to connect the first frame bodies 111 and 121 and the second frame bodies 112 and 122 before the door frame 1 is installed in the opening. Accordingly, the door frame 1 can be installed after the wall surface panel P is bonded to the column member Kx and the beam member Ky. Also, since the second frame 112, 122 is only sandwiched between the door stop portions 111a, 121a and the holding portions 111b, 121b, due to the construction error of the column member Kx and the beam member Ky that form the opening K, Even if the wall thickness is increased or decreased, the degree of overlap between the door stop portions 111a and 121a and the inner front end portions of the second frames 112 and 122 only changes. For example, even if the overlapping degree is changed, the appearance is not changed because it is hidden by the door stop portions 111a and 121a. Therefore, the door frame 1 according to the present embodiment has both the ability to cope with an error in the wall thickness of the opening and the good workability.

  Moreover, if the first frame bodies 111 and 121 in which the door stop portions 111a and 121a and the holding portions 111b and 121b are formed in advance, the wall thickness is finally determined at the design stage. Even when the second frames 112 and 122 are produced, the shapes of the second frames 112 and 122 are simpler than the first frames 111 and 121, and are simply a structure in which a steel plate is simply bent into an L shape. Therefore, it can be produced in a short time. Therefore, since it can respond even in a short delivery time, it can prepare for construction quickly.

In the present embodiment, since the first frame bodies 111 and 121 and the second frame bodies 112 and 122 are divided into the vertical frame portion 11 and the horizontal frame portion 12, the storage space can be saved. It can be easily carried into the construction site. This division may be either the vertical frame portion 11 or the horizontal frame portion 12.
In addition, when installing the door frame 1 which concerns on this Embodiment in the opening part in which a fire prevention door is provided, by making the vertical frame part 11 and the horizontal frame part 12 into the integral structure instead of the connection by screwing. The required strength can be ensured.

  In the present embodiment, the first frame body 111 and the column member Kx, and the first frame body 121 and the beam member Ky are connected by the L-shaped plates 142, or the locking member 131 and the hook plate 132 are connected. For example, as shown in FIG. 8A and FIG. 8B, the first frame body 111 and the column member Kx, and the first frame body 121 and the beam member Ky, The fixing space R can be used as a welding space and can be fixed by welding with an anchor 18 (connection rod) interposed. However, when the first frames 111 and 121 are fixed by welding, the welding flame that scatters from the tip of the welding rod for electric welding toward the back side of the fixing space R is on the opening K side of the wall panel P. There is a risk of scorching the edges. Therefore, it is better to perform the connection by screwing or locking rather than the connection by welding as in the present embodiment. By doing so, the door frame 1 can be safely attached even in a state where the wall surface panel P is pasted as the wall surface S1, S2, a state where a cloth is pasted on the wall surface panel P, and a state where the wall surface S1, S2 is painted. .

  In addition, the U-shaped plate 141 is screwed together with the hinge H to the hinge H where the load is most applied when the hinged door 2 is opened and closed, so that the U-shaped plate 141 fixes the first frame body 111. As well as a reinforcing member that reinforces the first frame 111. In addition, by fixing the U-shaped plate 141 together with the hinge H, it is not necessary to perform welding or fixing with other screws.

  Further, in the present embodiment, the holding portions 111b and 121b are attached to the door stop portions 111a and 121a by welding, but may be integrally formed by bending.

(Modification)
Next, the modification of the door frame 1 which concerns on embodiment of this invention is demonstrated based on FIG. 9 and FIG. 9 and FIG. 10, the same components as those in FIG. 2 and FIG.

  The door frame 10 shown in FIGS. 9 and 10 is suitable when the weight of the hinged door 2 is heavy. Each of the first frame bodies 111 and 121 of the door frame 10 is fixed to the column member Kx and the beam member Ky by a fixing member 17 which is a through metal fitting.

The fixing member 17 is an S-shaped connecting member in which a J-shaped frame body side screwing portion 171 and an L-shaped frame member side screwing portion 172 are integrally formed.
The J-shaped frame body side screwing portion 171 is located on the back side behind the first frame bodies 111 and 121 and is screwed to the first frame bodies 111 and 121 from the front surface side.
The L-shaped frame member side screwing portion 172 is bent and screwed along the column member Kx or the beam member Ky from the door stop portion 121a toward the column member Kx or the beam member Ky.
The fixing position of the fixing member 17 to the column member Kx is three positions of the hinge H (see FIG. 2), two positions between the hinges H, a position between the upper end and the hinge H, and a lower end. To 7 locations with hinges H. Further, the screwing position with the beam member Ky is one place in the central portion.

The fixing member 17 is screwed in a state in which the fixing member 17 is in contact with the back side surfaces of the first frame bodies 111 and 121 and the mounting surfaces of the column member Kx and the beam member Ky, so that the first frame body 111 is fixed to the beam.
