Description

The present invention relates to a frame opening mounting structure for a floor, and more particularly to a frame opening mounting structure for an underfloor storage or an inspection port.

Conventionally, a frame body is attached to an opening portion of the floor formed for an underfloor storage or an inspection port so that a lid that can open and close the opening can be stably supported and installed. I am trying.

By the way, if there is ventilation between the inside and outside of the room with the lid installed, the cooling and heating efficiency will decrease.Therefore, the frame has sufficient airtightness with the floor and sufficient strength to withstand the load. In addition to the requirement, it is necessary to reduce the level difference with the floor to prevent stumbling and to improve workability and handleability during construction.

In order to meet these demands, the frame is attached to the floor or joists supporting the floor (for example, refer to Patent Documents 1 and 2).

By the way, in the case of the conventional floor opening frame attachment structure in which the floor opening frame is attached to the floor or joists supporting the floor, when a construction defect is found or floor material laying work is performed. Therefore, there is a problem that it is difficult to adjust the mounting position of the frame body after once fixing the frame body.

SUMMARY OF THE INVENTION In view of the problems of the above-described conventional frame frame attachment structure for the floor opening, it is possible to easily adjust the attachment position of the frame body even after the frame body is once fixed. The frame can be installed with high dimensional accuracy, and it is possible to obtain high airtightness with the floor and sufficient strength to withstand loads, and to prevent stumbling by reducing the step with the floor surface. At the same time, it is an object of the present invention to provide a mounting structure for a frame of an opening in a floor, which can improve workability and handleability during construction.

In order to achieve the above-mentioned object, a frame opening mounting structure of the present invention is a frame support member for mounting a frame arranged in a floor opening with a screw to a floor side mounting part. In the mounting structure of the frame of the floor opening which is supported and fixed via the frame, the mounting position of the frame supporting member or the frame can be changed in the vertical direction with respect to the fixing position of the screw. It is characterized in that a position adjusting means is provided.

In this case, the position adjusting means can be configured by a screw insertion hole formed of a long hole formed in the frame body supporting member.

Further, the position adjusting means may be composed of a fixing portion having a serration structure capable of changing and fixing the relative positions of the frame body supporting member and the frame body in the vertical direction.

Further, the position adjusting means may be composed of a fixing portion having a screw structure capable of changing and fixing the relative positions of the frame body supporting member and the frame body in the vertical direction.

According to the attachment structure of the frame of the opening of the floor of the present invention, the frame disposed in the opening of the floor is supported via the frame support member attached to the attachment on the floor by screws, In the mounting structure of the frame body of the opening portion of the floor that is fixed, a position adjusting means that can change the mounting position of the frame body supporting member or the frame body with respect to the fixing position of the screw in the vertical direction is provided. Therefore, the mounting position of the frame body can be easily adjusted even after the frame body is once fixed, which allows the frame body to be installed with high dimensional accuracy and high airtightness with the floor. It is possible to obtain sufficient strength to withstand the load and load and to prevent stumbling by reducing the step difference with the floor surface, and to improve workability and handleability during construction.

In this case, the fixing portions 4 of the serration (saw tooth) structures 12 and 22 have a shape that restricts the change of the relative position of the frame body 1 in the upward direction with respect to the frame body supporting member 2 (detent). The operation piece 23 for releasing this restriction is provided on the frame body supporting member 2.

The frame support member 2 is arranged in the installation portion 11 formed in the frame body 1 so that relative position adjustment in the vertical direction is possible. Therefore, the vertical dimension of the installation portion 11 is set. Is larger than the vertical dimension of the frame support member 2 by several mm to 10 mm, for example.

The frame body supporting member 2 is configured to maintain the vertical position of the frame body 1 by the fixing portions 4 of the serration (sawtooth) structures 12 and 22, and the load applied to the lid body (not shown). , The outer frame is mainly supported by the collar portion.

FIGS. 2-1(c) and FIGS. 7 to 8 show a third embodiment of the attachment structure of the frame body of the opening portion of the floor of the present invention.
In this mounting structure of the frame body of the opening portion of the floor, the frame body 1 arranged in the opening portion of the floor F is attached to the mounting portion on the floor F side, in this embodiment, the joist J by the screw 3. The frame supporting member 2 is supported and fixed via the frame supporting member 2. As a position adjusting means for vertically fixing the mounting position of the frame 1 with respect to the fixing position of the screw 3, the frame supporting member is provided. A fixing portion 5 having a screw structure that can change and fix the vertical position of the frame 1 with respect to the member 2 is provided.

The frame support member 2 is arranged in the installation part 11 formed in the frame 1 so that relative position adjustment can be performed in the vertical direction and the horizontal direction. Therefore, the vertical direction of the installation part 11 can be adjusted. The horizontal and horizontal dimensions are made larger than the vertical and horizontal dimensions of the frame support member 2 by, for example, several mm to 10 mm and several mm to 20 mm, respectively.

The frame body supporting member 2 is configured to maintain the vertical position of the frame body 1 by the fixing portion 5 having a screw structure, and the load applied to the lid body (not shown) is mainly the flange of the outer frame. I try to support it by the department.

FIGS. 2-2(d) and FIGS. 9 to 10 show a fourth embodiment (a modification of the first embodiment) of the attachment structure of the frame of the opening of the floor of the present invention.
In this mounting structure of the frame body of the opening portion of the floor, the frame body 1 arranged in the opening portion of the floor F is attached to the mounting portion on the floor F side, in this embodiment, the joist J by the screw 3. It is configured to be supported and fixed via the frame body supporting member 2, and the mounting position of the frame body supporting member 2 (and the frame body 1 via the frame body supporting member 2) with respect to the fixing position of the screw 3. As a position adjusting means that can be changed in the vertical direction and fixed, a screw insertion hole 21 formed of a horizontally elongated hole formed in the frame body supporting member 2 is provided.

In this case, the frame body supporting member 2 is arranged in the installation portion 11 which is formed in the frame body 1 so as to be inclined with respect to the horizontal direction. The size of the installation portion 11 in the horizontal direction is made larger than the size of the frame support member 2 in the horizontal direction by, for example, several mm to 20 mm.

Since the frame body supporting member 2 is arranged in the installation portion 11 formed on the frame body 1 and is in contact with the frame body 1 in the vertical direction, in addition to maintaining the vertical position of the frame body 1, Thus, the load applied to the lid (not shown) is shared by the flange portion of the outer frame and supported.

FIG. 2-2(e) and FIGS. 11 to 12 show a fifth embodiment of the attachment structure of the frame of the opening of the floor of the present invention.
In this mounting structure of the frame body of the opening portion of the floor, the frame body 1 arranged in the opening portion of the floor F is attached to the mounting portion on the floor F side, that is, the joist J in this embodiment, with the screw 3.
