Description

The present invention relates to a door structure provided with a door closer and a construction method thereof.

The door closer works to automatically close the open door at a relatively slow speed, and you do not need to hold your hand until the door closes, so you can prevent accidents of pinching your fingers and when you close the door Not only metal doors such as aluminum and steel, but also wooden doors used as entrance doors and interior doors in various facilities such as hospitals and general houses are widely used because they have the advantage of reducing the noise generated in the doors. It has come to be used.

The door closer consists of a closer body that houses the main mechanical parts such as the hydraulic mechanism, an arm that is rotatably connected to the main body at one end, and a rail part that is rotatably and slidably connected to the other end of the arm. The closer body is provided on either the door frame (upper frame) or the door so that it cannot be seen from the outside, and the rail portion is provided on the other side, and these are connected so as to be openable and closable by an arm. There is. In Patent Document 1, the check body (closer body) of the door check 2 (door closer) is housed and fixed in the recess 3A formed from the lower surface of the upper frame member (upper frame), and the attachment portion 6 is accommodated and fixed to the door 1 (door closer). The configuration attached to the upper end of the door) is shown (Fig. 1).

Japanese Unexamined Patent Publication No. 4-111881

When the closer body is attached to the lower surface of the upper frame as in Patent Document 1, a recess having a size equal to or larger than the length (height) of the closer body must be formed on the lower surface of the upper frame. Since the main mechanism such as the hydraulic mechanism is built in, there is a limit to miniaturization, and in the case of a closer body with a height dimension exceeding the thickness of the upper frame, the door closer fits as described in Patent Document 1. Cannot be adopted.

In this case, increase the thickness dimension of the upper frame, or leave the thickness dimension of the upper frame as it is, form a through hole that penetrates the upper frame in the thickness direction, and accommodate the closer body in this through hole. It was necessary to form a recess for accommodating the closer body protruding above the upper frame into a gusset provided in contact with the upper surface of the upper frame. However, according to the former, the thickness dimension of the upper frame becomes large, and it is not possible to obtain a door structure with a neat impression. Further, according to the latter, at the door construction site, the recess must be formed in the lintel so that the recess is aligned with the through hole of the upper frame, which is troublesome for construction.

Contrary to Patent Document 1, it is also possible to adopt a configuration in which the closer body is provided at the upper end of the door and is connected to the rail portion provided on the upper frame by an arm, but in this case, the closer body is accommodated. In order to do so, a recess of substantially the same size must be formed at the top of the door. As mentioned above, the closer body must have a certain size, so the recesses for accommodating it occupy a considerable proportion of the thickness and width of the door, especially in fire protection doors. May reduce fire protection performance. Further, depending on the shape of the closer body, it is difficult to accommodate the door in the recess of the upper end of the door without a gap, and if a gap is generated, the flame easily passes through this gap in the event of a fire, which deteriorates the fire prevention performance. It contributes.

Therefore, the problem to be solved by the present invention is to provide a new door structure in which the door closer fits well and does not deteriorate the fire prevention performance, and to provide an efficient construction method thereof.

In order to solve the above problems, the present invention according to claim 1 has a frame body provided in an opening formed by a pair of left and right columns and a horizontal member connecting the upper ends thereof, and the frame body can be opened and closed freely in the frame body. A door structure including a door to be provided, a closer body fixed to an upper frame of a frame body, a rail portion fixed to an upper end portion of the door, and a door closer having an arm connecting the closer body and the rail portion. The upper frame is formed with a through hole for accommodating the lower portion of the closer body, and is formed so as to communicate with the through hole by at least one base rail provided between the upper frame and the horizontal member. The door structure is characterized in that the upper part of the closer body is accommodated in the accommodation space.

The present invention according to claim 2 is characterized in that, in the door structure according to claim 1, the found dimension of the accommodation space is formed to be larger than the found dimension of the through hole.

The present invention according to claim 3 is a construction method for obtaining the door structure according to claim 1 or 2, wherein at least one is formed on the upper surface of an upper frame or the lower surface of a horizontal member in which a through hole is formed in advance at a predetermined position. By fixing the base rail between the pair of left and right columns and fixing the base rail between the upper frame and the horizontal member, the base between the upper frame and the horizontal member The process of forming the accommodation space surrounded by the crosspieces above the through hole of the upper frame, and fixing the closer body to the upper frame while fitting it to the through hole and the accommodation space, and attaching the rail part to the upper end of the door. It is characterized by having a process of attaching a door closer by fixing it to a formed recess and connecting a closer body and a rail portion with an arm, and a process of attaching the door to either the left or right vertical frame so as to be openable and closable. ..

According to the first aspect of the present invention, the base rail provided between the upper frame and the horizontal member forms a storage space communicating with the upper part of the through hole of the upper frame, so that the lower portion of the closer body is formed. Can be installed in the through hole so that the upper portion protruding from the through hole is accommodated in the accommodation space. Therefore, even if the size of the closer body is large, it is not necessary to make the upper frame thicker according to the size of the closer body, and the upper portion of the closer body is accommodated in the lower surface of the horizontal member. Since it is not necessary to form a recess for the purpose, the construction is easy and the closer body can be fitted in a good appearance. Further, since it is only necessary to form a recess in the door for accommodating a relatively small rail portion, it is possible to prevent deterioration of fire prevention performance even when the door is used as a fire prevention door.

According to the second aspect of the present invention, since the found dimension of the accommodation space formed by the base rail is formed to be larger than the found dimension of the through hole, the frame is slightly fixed to the pillar or the base rail. Even if the finding direction of the closer is deviated, the closer body can be accommodated across the through hole and the accommodating space.

According to the third aspect of the present invention, there is provided a method for constructing the door structure according to claim 1 or 2 with high work efficiency. By the process of fixing the base rail and the step of fixing the frame body, a storage space surrounded by the base rail is formed between the upper frame and the horizontal member so as to communicate with each other above the through hole of the upper frame. , The closer body can be installed so as to straddle these through holes and the accommodation space.

Hereinafter, the present invention will be described in detail with reference to examples. In FIGS. 1 to 10, one or the corresponding member or element is designated by the same reference numeral.

A door structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8. The door structure 10 includes a three-sided frame composed of an upper frame 11 and left and right vertical frames 12, 12, a lintel set door 13 that can be opened and closed in the three-sided frame, and a pillar 14 erected on the outside of the three-sided frame. , 14, the lintel 15 which is a horizontal member connecting the upper ends of the pillars 14, 14, and the base rails 16, 17, 18 and the pillar 14, which are arranged between the upper frame 11 and the lintel 15. It is composed of a plaster board 19 laid on the outside of 14 and a lintel 15 and a door closer 20. The door closer 20 has a closer body 21, an arm 22, and a rail portion 23, as described above in relation to the prior art.

In particular, with reference to FIGS. 4 and 5, a recess 24 for accommodating the rail portion 23 of the door closer 20 is formed at a predetermined position at the upper end end of the door 13, and the upper portion thereof opens on the back surface of the door 13. It is extended, and the arm 22 of the door closer 20 is rotatably housed in the upper portion thereof. Further, a through hole 25 is formed in the upper frame 11 at a position where the door 13 is aligned substantially directly above the recess 24 when the door 13 is closed. The through hole 25 has a horizontal dimension sufficient to accommodate the lower portion of the closer body 21, but the thickness of the upper frame 11 is smaller than the height dimension of the closer body 21 (less than half in the illustrated example). The upper portion of the main body 21 penetrates the through hole 25 and protrudes above the upper frame 11.

In order to allow the upper portion of the closer body 21 to protrude, the base bars 16, 17, and 18 are provided between the upper frame 11 and the magusa 15 to form the accommodation space 26. The base rails 16, 17 and 18 are delivered in a state that matches the estimated and found dimensions of the construction site, and the expected dimensions of the base rails 16 and 17 are substantially the same as the estimated dimensions of the through hole 25 of the upper frame 11. The base rail 18 is substantially the same as the size obtained by subtracting the expected dimensions of the base rails 16 and 17 from the estimated dimensions of the construction site (expected dimensions of the magusa 15). Regarding the found dimensions, the base rail 18 is substantially the same as the found dimensions at the construction site (dimensions between the pillars 14 and 14), and the total found dimensions of the base bars 16 and 17 are the found dimensions at the construction site (base). It is substantially the same as the dimension obtained by subtracting the found dimension of the through hole 25 from the found dimension of the crosspiece 18). That is, the base rail 16 extends from the pillar 14 on one side (left side in FIGS. 1 to 3) by the required found dimension, and the base rail 17 extends from the pillar 14 on the other side (right side in FIGS. 1 to 3). It is arranged so as to extend by an additional dimension and open a through hole 25 having a predetermined found dimension corresponding to the size of the closer body 21 between them. In this way, the accommodation space 26 surrounded by the base rails 16, 17, and 18 is formed between the upper frame 11 and the magusa 15 so as to be substantially aligned above the through hole 25, and is formed in the accommodation space 26. The upper portion of the closer body 21 is accommodated (FIG. 4).

The accommodation space 26 formed between the upper frame 11 and the magusa 15 by the base bars 16, 17, and 18 communicates with the upper part of the through hole 25 formed in the upper frame 11, but the found size thereof is as follows. It is preferable to form the through hole 25 so as to be slightly larger than the found size (FIG. 8). By doing so, even if a slight deviation in the finding direction occurs when the three-sided frame consisting of the upper frame 11 and the left and right vertical frames 12, 12 is fixed to the pillars 14, 14 and the base bars 16, 17, 18 , Prevents the closer body 21 from being unable to be accommodated across the through hole 25 and the accommodation space 26.

In FIGS. 4 and 5, reference numeral 27 is a door stop, and reference numeral 28 is a packing made of a cushioning material provided inside the door stop 27 in order to improve airtightness when the door is closed.

The closer main body 21 is formed in the through hole 25 formed in the upper frame 11 and the accommodation space 26 formed by the base bars 16, 17, 18 between the upper frame 11 and the magusa 15 as described above. In a state of being accommodated straddling the space, the lower surface of the closer body 21 and the lower surface of the upper frame 11 are fixed to the upper frame 11 with screws (not shown) so as to be substantially flush with each other. The rail portion 23 is fixed to the door 13 with a screw (not shown) or the like in a state of being housed in the recess 24 formed in the upper end end of the door 13.

According to the door structure described above, the front and rear surfaces of the closer body 21 and the base bars 16, 17 and 18 are covered with the gypsum boards 19 and 19 fixed to the pillars 14 and 14 and the lintel 15 to the outside. It is not exposed and the appearance is not spoiled.

The construction of this door structure consists of (1) the steps of fixing the base rails 16, 17, and 18 to the lower surface of the lintel 15, and (2) the upper frame 11 and the left and right vertical frames in which the through holes 25 are formed in advance at predetermined positions. The process of fixing the three-sided frame consisting of 12 and 12 to the pillars 14, 14 and the base rails 16, 17 and 18, (3) the process of attaching the door closer 20, and (4) the door 13 with hinges (not shown). It can be performed by the step of fixing to the vertical frame 12. By the steps (1) and (2) above, the accommodation space 26 surrounded by the base rails 16, 17 and 18 between the upper frame 11 and the lintel 15 communicates above the through hole 25 of the upper frame 11. In the step (3) above, the closer main body 21 is fixed to the upper frame 11 in a state of being accommodated across the through hole 25 and the accommodation space 26, and the rail portion 23 is fixed to the upper end end of the door 13. This can be done by connecting the closer body 21 and the rail portion 23 with the arm 22 after fixing the closer body 21 and the rail portion 23 in a state of being housed in the recess 24 formed in the door 13.

In addition, in the step (1) above, instead of fixing the base bars 16, 17, 18 to the lower surface of the magus 15, it is fixed to the upper surface of the upper frame 11, and in the step (2) above, it is already above. The base bars 16, 17, and 18 fixed to the upper surface of the frame 11 may be fixed to the magus 15. Also in this case, at the time of passing through the steps (1) and (2), the accommodation space 26 surrounded by the base rails 16, 17, and 18 between the upper frame 11 and the magusa 15 is a through hole of the upper frame 11. It will be formed so as to communicate with the upper part of 25.

Although the present invention has been described in detail in the above, the present invention is not limited to this embodiment, and is variously modified within the scope of the invention defined based on the description of the claims. Or it can be changed and implemented.

For example, in the above embodiment, the base rail 18 having a found dimension extending between the columns 14 and 14 is used, but at a found position matching the through hole 25, at least the found dimension of the through hole 25 or more is used. It may have the found size of the above and form the accommodation space 26 in cooperation with the base bars 16 and 17.

Further, in the above embodiment, three base bars 16, 17, and 18 are provided at predetermined positions between the upper frame 11 and the magusa 15 to form the accommodation space 26, but the through hole 25 of the upper frame 11 is formed. The number is arbitrary as long as it can communicate upward to form the accommodation space 26. For example, the accommodation space 26 may be formed by a single base rail 29 in which the ones corresponding to the base rails 16, 17, and 18 in the above embodiment are integrated (FIG. 9), and the single base rail 29 may be formed. A base rail 30 having a shortened found size may be provided so as to surround the through hole 25 to form a storage space 26 (FIG. 10). Further, although not shown, in the embodiment shown in FIG. 10, a single base rail 30 is divided into three base rails in the same manner as in the above embodiment, and each of them is arranged and fixed at a predetermined position. The accommodation space 26 may be formed.

Further, although the door 13 of the frame is used in the above embodiment, the door configuration is arbitrary, and the present invention can be applied even to a door having a flash structure, for example. Further, in the above embodiment, the base rails 16, 17, and 18 are fixed to the lower surface of the magus 15, but instead of this, they may be fixed to the upper surface of the upper frame 11.
