Description

Description: TECHNICAL FIELD The present invention relates to a door sash mounting structure.

(Prior Art) Mounting of a sash for a door, particularly mounting of a lower frame body that is a so-called sill after mounting the sash for the door, is usually accompanied by mortar construction.

However, if the lower frame of the door sash is fixed only by filling it with mortar or concrete, the lower frame will be free until it is embedded, so if the lower frame receives external force during construction, it will deform. It is easy to do, and there is a risk that it will be displaced from the predetermined mounting position.

In addition, such a wet mounting method requires the work of placing mortar and concrete, which prolongs the construction period, and especially when installing a door on the second floor or above, there is a problem of cracks such as mortar. Occurs.

Therefore, regardless of whether or not the lower frame is embedded in mortar or concrete, the sash base is mounted on the flange of the support made of H-shaped steel or the like that functions as a horizontal beam so that the lower frame can be fixed at an accurate position. A mounting structure for a door sash has been proposed in which the base is fixed and the lower frame of the door sash is fixed to the upper part of the sash base (see Japanese Utility Model Laid-Open No. 61-102774).

(Problems to be Solved by the Invention) In the conventional mounting structure described in the above publication, the sash base is composed of a connecting fitting which is formed by bending the laterally extending piece and the rising piece into a substantially L-shape in a side view. By bolting the lateral piece to the flange of the support (H-shaped steel) and bolting the rising piece of the connecting bracket to the inside of the lower frame of the door sash, the lower frame is used as the support. I'm trying to fix it.

However, in such a conventional mounting structure, the lateral piece is largely displaced from the flange of the support toward the indoor side,
Since the lower frame is fixed to the rising piece located at the indoor end of the lateral piece, the lower frame is supported in a cantilevered manner with respect to the lateral piece extending from the flange to the indoor side.

Therefore, in this case, when a person rides on the lower frame that serves as the door sill after the construction, the laterally extending piece that greatly extends to the indoor side is likely to be deformed downward, and therefore the lower frame is also easily deformed at the same time. Therefore, in order to prevent such deformation of the lower frame body, the lower frame body must be embedded in mortar or the like after all.

Further, in the past, only the indoor side of the lower frame is fixed to the rising piece, and the outdoor side of the frame is not fixed at all, so unless the lower frame is embedded in mortar, etc. It is difficult to firmly fix the lower frame to the support only with the base.

In view of such circumstances, the present invention provides a door sash mounting structure in which the lower frame is mounted on a support made of H-shaped steel or the like via a sash base, and the lower frame is made of mortar or concrete. It is an object of the present invention to prevent the lower frame body from being deformed by a load of about the weight of a person without being embedded, and moreover, to firmly fix the lower frame body to a support body.

(Means for Solving the Problem) In order to achieve the object, the technical means taken by the present invention are:
In a door sash mounting structure in which a lower frame 1 of a door sash 3 is fixed on a support 13 which is a horizontal member via a sash base 4, the lower frame 1 is an indoor side. Has a sash mounting plate 27 extending in parallel with the sash base 4. The sash base 4 is connected to a long plate-shaped substrate portion 5 through a vertical wall standing upward from the substrate portion 5 and is parallel to the substrate portion 5. A first mounting plate 6a and a second mounting plate 12 extending to the inside of the room, and the board portion 5 is mounted on and fixed to the support body 13, and the lower frame body 1 is attached to the sash. First mounting plate of base 4
6a, the lower frame 1 is fixed to the first mounting plate 6a on the outdoor side, and the sash mounting plate 27 is fixed to the second mounting plate 12.

(Operation) According to the present invention, the sash base 4 is connected to the long plate-shaped substrate portion 5 mounted on and fixed to the support body 13 through the vertical wall standing upright from the substrate portion 5. The first mounting plate 6a provided,
The second mounting plate 12 located on the indoor side is provided, and the lower frame 1 is mounted and fixed on the first mounting plate 6a of the sash base 4.

In this case, when the sash base 4 is located directly above the support 13 and the lower frame 1 is placed directly above this sash base 4, these three members 13, 4, 1 Since they are fixed to each other, even if a person rides on the lower frame 1 that serves as a door sill after construction, the load applied to the lower frame 1 is transmitted to the sash base 4 immediately below the lower frame 1, and Since it is directly supported by the support 13 immediately above, it is possible to prevent the lower frame 1 from being deformed even when a load of about the weight of a person is applied.

In this case, the lower frame 1 is fixed to the first mounting plate 6a on the outdoor side, and the sash mounting plate 27 extending from the lower frame 1 to the indoor side is fixed to the second mounting plate 12. Therefore, even if the lower frame 1 is not embedded with mortar or the like, the lower frame 1 can be firmly fixed to the support 13 only by the sash base 4.
