Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door frame end mounting tool for mounting on the upper end of a vertical frame of a door frame that constitutes a door part of a concrete structure.

[0002]

[Prior art]

 The door frame that frames the door of a reinforced concrete structure is formed by welding a vertical metal frame and a vertical frame with protruding doorstops into an enclosed shape, which is also supported by braces or anchor bolts. It is attached to the steel frame and fixed in place, and mortar is applied to the surrounding area.

As shown in FIG. 3, this frame member has a C-channel (lip groove-shaped) inner surface (opposite of the opening) in which the opening 23 is located on the wall side, that is, on the outer peripheral side of the frame. The vertical frame 21 and the upper and lower frames 22 usually have a shape in which a door stop 24 is provided on one side (side surface), and the door stop on the upper side of the vertical frame 21 has a notch 25, The upper frame 22 is placed on the notch to weld them together. At this time, the upper frame 22 extends only the C-channel outer side folded piece 22a in the longitudinal direction, and the extended piece 22b closes the upper end opening 27 of the U-shaped portion 26 on both sides of the C channel of the vertical frame 21. Then, the peripheral edge of the extending piece 22b and the end edge of the U-shaped portion 26 are welded.

The meaning of the obstruction by the extension piece 22b varies depending on the purpose, but it is intended to prevent the mortar from falling and tools from falling, and to close the ventilation gap.

[0005]

[Problems to be solved by the device]

 However, in order to form the extension piece 22b, it is necessary to cut off the other portions while leaving only the C-channel folded pieces 22a at both ends of the upper frame, and the extension piece 22b and the vertical frame Since it was necessary to weld the character portion 26 to the welded portion, the work burden and the cost burden were overloaded.

The present invention has been made in view of the above problems, and was created from the idea of simply and effectively closing the upper end opening of the U-shaped portion described above without incurring work burden and cost burden. The object is to provide a door frame end fitting which can be easily manufactured and whose workability is improved by simple handling, and which can be securely closed.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a fitting insertion portion that fits into an upper end opening of a U-shaped portion formed on both sides of a vertical frame in a door frame, and a side edge. And a top surface, which constitutes a non-combustible door frame end fitting.

In the above-mentioned configuration, it is preferable that the upper surface is formed to be substantially flush with the folded piece of the U-shaped portion formed on both sides of the upper frame.

[0009]

[Action]

 The door frame end fitting can be inserted at any time into the U-shaped portion of the upper end of the vertical frame.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a perspective view showing an upper end portion of the door frame according to the present invention, in which the vertical frame 11 has a tip of a folding piece 14 forming a C-channel-shaped opening 13 and is further folded outward as shown. It is made to project (this projecting part does not have to be formed), and the inside of the folding piece 14 has a U-shaped part 15, and a door stopper 16 is provided to project to one side of the inner surface. I am doing it.

The upper frame 12 has substantially the same cross-sectional shape as the vertical frame 11 (the reference numerals are the same as above), and the length in the inward / outward direction from the bottom of the folding piece 14 to the inner surface of the door stop 16. The upper part of the door stop 16 of the vertical frame 11 is cut off from the upper end 17 by a length substantially equal to A, and the end of the upper frame 12 is placed on the upper side of the door stop 16 that was cut off 17, and the inner surface of the vertical frame 11 is cut. The end face of the upper frame 12 is brought into contact with and is integrally welded. In FIG. 2, what is indicated by a chain line outside the vertical frame 11 is an example of a mortar wall.

Then, the door frame end fitting 1 is fitted into the upper end of the U-shaped portion 15 of the vertical frame 11 from above. This fitting can be performed before the upper frame 12 is assembled or after the vertical frame 11 is manufactured by the factory. As shown in FIG. 1, the door frame end fitting 1 has a fitting portion 2 that can be manually press-fitted in a U-shaped portion 15 of a vertical frame 11 and has a U-shaped portion 15 on an upper side thereof. The upper surface 3 is integrally formed to have a size capable of closing the upper surface, and which has an overhanging edge 4 which is appropriately protruded from the fitting insertion portion 2, for example, about the thickness of the frame material of the vertical frame 11 to the side. It is made of non-combustible material such as metal.

In the case of a metal material, press working is simple and inexpensive, and in the example of FIG. 1, one side portion of the upper surface 3 is bent downward by a plate body having a desired thickness, and the folded piece of the vertical frame 11 is bent. 14 form a lower bent piece 5 slightly narrower than the gap between the inner side surface and the inner side surface, and bend the strips extending on both left and right sides of the lower bent piece 5 inwardly by a little less than 90 ° to fold each other. Press-fitting side pieces 6 and 6 are formed, which are slightly expanded on the tip side from the curved root portion and located on the lower side of the upper surface 3 at a position appropriately inward of the projecting edge 4. The pieces 6 and 6 form a U-shaped fitting insertion portion 2 in a plan view. Fitting guide pieces 7, 7 are formed on the middle side of the press-fitting side pieces 6, 6 and on the lower side near the tips, respectively.

When the door frame end fitting 1 is pushed into the U-shaped portion 15 of the vertical frame 11 from above, the tips of the fitting guide pieces 7, 7 are recessed, and thus the guide is guided by this. The lower bent piece 5 and the press-fitting side pieces 6 and 6 are fitted in, the press-fitting side pieces 6 and 6 are pressed against the opposite side surfaces of the U-shaped portion 15, and the upper surface 3 is brought into contact with the end surface of the U-shaped portion 15. And sticks. The upper surface 3 is substantially flush with the folded piece 14 of the upper frame 12.

The door frame end fitting according to the present invention has the above-described example as long as it has a fitting insertion portion press-fitted into the U-shaped portion 15 and an upper surface abutting the end surface of the U-shaped portion. Not limited to.

[0016]

[Effect of device]

 As described above, according to the present invention, the door frame end fitting can be manufactured easily and inexpensively, and the opening in the U-shaped portion formed at the upper end of the vertical frame in the door frame can be easily manufactured at any time. Since it can be closed manually, the work of closing by welding is not required, and the work of joining the upper frame can be simplified.
