  The reinforcing member 6 has engaging portions 35 at both ends, and these engaging portions 35 abut against the inner surface of each vertical frame 3, so that the reinforcing member 6 is accurately positioned and the deformation of the three-way frame 1, that is, Opening and closing of both vertical frames 3 are prevented.

  In this way, the reinforcing members 5 and 6 are attached to the lower part on the front side and the lower part on the back side of the three-way frame 1, respectively. In this state, the three-way frame 1 is shipped from the factory and transported to the construction site. Then, at the construction site, the three-way frame 1 is installed at the elevator hall 50 as shown in FIG. FIG. 6 is a cross-sectional view of the landing entrance 50 as seen from above. 51 is a building wall of the building, 52 is a hoistway, and 53 is an elevator hall of the building.

  The installation procedure of the three-sided frame 1 will be described. First, the three-sided frame 1 is set on the floor surface of the hall 50 with both the vertical frames 3 facing downward. At this time, since there is no equipment such as a reinforcing member on the lower end surfaces of both the vertical frames 3, the three-sided frame 1 can be set on the floor surface of the hall 50 as it is.

  Next, the three-way frame 1 is fastened and fixed to the frame wall 51 using a predetermined beam material or a fastening material (not shown). At this time, the first and second reinforcing members 5 and 6 are attached to the three-way frame 1 and are in a sufficiently reinforced state. Therefore, the deformation of the three-way frame 1 can be reliably prevented, and the three-way frame 1 has a predetermined specification. It can be fixed to the hall 50 while maintaining this form.

  Thereafter, the fastening bolts 26 and 42 of the first and second reinforcing members 5 and 6 are extracted, and the first and second reinforcing members 5 and 6 are removed from the three-way frame 1. Thereby, the installation work of the three-way frame 1 to the hall 50 is completed.

  3, 4, and 4, after installation of the three-way frame 1, between the rear side end of each vertical frame 3 and the frame wall 51 and between the upper frame 2 and the frame wall 51, as necessary. 6, closing plates 60 and 61 as accessory parts of the three-way frame 1 are attached to close the respective gaps. Each of the closing plates 60 and 61 is made of, for example, a steel plate.

  As described above, according to the present embodiment, the three-sided frame 1 is fixed to the landing port 50 with the reinforcing members 5 and 6 being attached to the lower part on the front side and the lower part on the rear side of the three-sided frame 1, respectively. The construction process of removing the reinforcing members 5 and 6 can be adopted, so that the deformation of the three-sided frame 1 can be surely prevented even during the installation construction work, and the entire flow of the construction is set to the landing entrance 50 Thus, the two steps of fixing and fixing the reinforcing members 5 and 6 are sufficient, so that the construction process can be simplified and efficient construction can be achieved.

  By the way, the first reinforcing member 5 attached to the front surface of the three-way frame 1 is not directly fastened to the vertical frame 3 by the bolt 26, but is a presser 21 disposed inside the front plate 16 of the vertical frame 3. The bolt 26 is screwed into the vertical frame 3, and is fixed to the vertical frame 3 by tightening the bolt 26. For this reason, the front plate 16 of the vertical frame 3 exposed to the elevator hole is formed with a screw hole through which the bolt 26 is passed. Therefore, the front plate 16 can be kept beautiful, and the design of the three-sided frame 1 is not impaired.

  In addition, in the said embodiment, although the engaging part 10 for positioning of the 1st reinforcement member 5 was comprised by bending a part of board | plate material of the reinforcement member 5, it shows as FIG. 7 as 2nd Embodiment. Thus, an opening 70 is formed at the end of the reinforcing member 5, and an L-shaped metal fitting 71 is inserted into the opening 70 and fixed to the reinforcing member 5 with a bolt 72. It is also possible to form the positioning engaging portion 10 with the protruding portion.

  Alternatively, as shown in FIG. 8 as the third embodiment, a pin member 74 such as a rivet or a bolt is inserted and fixed to the end of the reinforcing member 5 and protrudes to the surface side of the reinforcing member 5 of these pin members 74. It is also possible to configure the engaging portion 10 for positioning by the portion to be performed.

  FIG. 9 shows a fourth embodiment. In this embodiment, the edge of the bent piece 31 of the second reinforcing member 6 is used as a scale for measuring dimensions along the longitudinal direction of the edge. A plurality of functioning cutout grooves 76a, 76b, and 76c having different lengths are formed.

  The opening size of the landing entrance 50 where the three-sided frame 1 is installed may be different for each building or floor. In this case, the dimensions between the three-way frame 1 installed at the landing port 50 and the opening edge of the landing port 50 are different. Therefore, when the closing plates 60 and 61 (see FIGS. 3, 4 and 6) for closing the gap between the three-sided frame 1 and the opening edge of the hall 50 are attached, the closing plate is measured while measuring the size of the gap. It is necessary to attach 60 and 61 to the dimension position as prescribed.

  In the fourth embodiment, since the plurality of cutout grooves 76a, 76b, and 76c as scales for measuring dimensions are formed at the edge of the second reinforcing member 6, the installation of the three-way frame 1 is completed. The second reinforcing member 6 removed from the three-way frame 1 can be used as a gauge for measuring dimensions when the closing plates 60 and 61 are attached. That is, the dimensions at the time of attaching the closing plates 60 and 61 are determined by the interval widths of the plurality of notch grooves 76a, 76b and 76c for dimension measurement formed at the edge of the reinforcing member 6 or combinations of the interval widths. Then, the closing plates 60 and 61 can be attached to the specified dimension positions. Note that the same scale for measuring dimensions can be provided also in the first reinforcing member 5.

  FIG. 10 shows a fifth embodiment. In this embodiment, in addition to the first reinforcing member 5 at the lower end on the front side of the three-sided frame 1, in addition to the upper and lower intermediate portions on the front side of the three-sided frame 1, A first reinforcing member 5 having the same structure is attached.

  Thus, a stronger reinforcement effect can be obtained by attaching the two reinforcing members 5 to the front side of the three-way frame 1. The reinforcing member 5 is not limited to two, and a plurality of reinforcing members 5 can be attached to further enhance the reinforcing effect.

  In addition, each said embodiment is shown as an example and is not intending limiting the range of invention. The novel embodiment of the present invention can be in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. The embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
