Description

DETAILED DESCRIPTION OF THE INVENTION The present invention primarily relates to an improvement in an elevator entrance/exit device installed in a steel structure building in which anchors and mortar cannot be embedded.

In elevators installed in buildings such as warehouses or steel frame buildings such as prefabricated structures, the threshold for guiding the entrance door on the landing side is a normal one because there is no concrete floor at the bottom of the threshold due to the structure of the building. It cannot be fixed using anchors and mortar like concrete buildings.

For this reason, a method is adopted in which separate metal fittings are installed and fixed using the steel frame at the bottom of the floor, but in the conventional installation structure, the metal fittings are welded or bolted to the steel frame and the sills are attached. was.

However, this installation structure had the drawback that the structure and accuracy of the building differed from floor to floor, requiring a huge amount of time and effort to assemble the actual building, lengthening the construction period and increasing costs.

Also, since it was a fitting process, the desired installation accuracy could not be achieved, and there was also a defect that the door opening/closing operation was not smooth.

The present invention was devised for the purpose of eliminating the drawbacks of the prior art, and provides an elevator entrance/exit device that does not require alignment work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of an elevator entrance/exit device according to the present invention will be described below with reference to the illustrated embodiment.

First, in the embodiment shown in FIGS. 1 to 5, 1 is a building floor, and 2 is a steel frame provided under the floor 1, which uses H-shaped steel.

The entrance/exit device of the present invention includes a sill plate 4, which is attached to a steel frame 2 through metal fittings.
It is characterized by adjustable installation of the threshold 3,
Pillars 7 supporting the rail case 8 are fixed at both ends of the sill 3, the door rail 14 inside the rail case 8 is suspended from a rolling hanging wheel 10, and the lower end is slid into the guide groove 3B of the sill 3 with a door shoe 11. When fitted, the door 9 can be opened and closed to the left and right.

Note that fixing the left and right columns 7 and the rail case 8 to the building is not directly related to the present invention, and will therefore be omitted.

Next, a structure for installing the sill 3 on the steel frame 2 will be explained.

The sill 3 has a shape as shown in cross section in FIG.

That is, it consists of a main body 3A, a guide groove 3B in which the door shoe 11 fits and slides above, and a dovetail-shaped mounting groove 3C in which the mounting bolt 12 is inserted on the back side, and the sill plate 4 has a long plate shape. None, but a mounting hole 4B for integration with the sill 3 and an elongated hole 4A for longitudinal adjustment are provided.

The sill plate 4 is provided for the purpose of reducing the cross-sectional capacity of the sill 3, and may be unnecessary depending on the shape of the sill 3.

By the way, the left metal fitting interposed between the steel frame 2 and the sill plate 4 is composed of a metal fitting 5 bolted to the sill 3 side and a metal fitting 6 fixed to the steel frame 2.

The metal fitting 5 is formed in an inverted shape with a short side 5A and a long side 5B forming a horizontal plane and a vertical plane, and the short side 5A has the dovetail-shaped mounting hole 3C for adjusting the depth direction of the entrance/exit. A vertically long elongated hole 5D is provided in the long side 5B of the orthogonal elongated hole 5C for vertical adjustment.

The metal fittings 6 are L-shaped with a vertical surface, and are fixed in advance to the steel frame 2 at appropriate intervals by welding or bolting.

Fix the metal fitting 5 using the vertical surface using the long hole 5D of the long side 5B with the mounting bolt 13, and then fix the metal fitting 5 using the long hole 5D of the short side 5A.
The sill 3 and the sill plate 4 are fixed with mounting bolts 12 via C.

Therefore, the sill 3 is formed by the mounting groove 3C and the elongated hole 4A of the sill plate 4 in the longitudinal direction, that is, the width direction of the entrance/exit, by the elongated hole 5C of the metal fitting 5 in the depth direction, and by the elongated hole 5D of the metal fitting 5 in the vertical direction.
It can be fixed adjustable in three directions.

The vertical elongated hole 5D of the metal fitting 5 may be provided on the metal fitting 6 side.

Also, to secure the metal fittings 5 and 6, use the mounting bolts 13 as shown in the figure.
After adjustment is made with one piece, it may be welded and fixed completely, or two or more pieces may be tightened and fixed.

Note that the metal fitting 6 is fixedly installed at the sill attachment position of the steel frame 2, and instead of fixing this metal fitting 6, it is possible to form the steel frame 2 itself so that the sill 3 can be attached, but this is not practical. Therefore, the fixing of the metal fittings 6 is indispensable for elevator entrance/exit devices installed in steel-framed buildings.

6 and 7 show another embodiment for fixing the metal fitting 6', in which the metal fitting 6' is attached to the steel frame 2 by welding on the lower surface of the steel frame 2 made of H steel.

Next, FIGS. 8 to 11 show another embodiment of the present invention, in which the overall configuration of the entrance and exit is the same as that of the previous embodiment, but the structure of the building floor 1 is such that mortar is dammed on the top of the steel frame 2. The steel frame 15 is equipped with a steel frame 15 that also serves as a bridge, and bolts are screwed in using the vertical surface of the steel frame 15, nuts 17 having a sufficient thickness T are fixed, and the special nuts 17 are used to connect the long side 16B and the short side. An L-shaped metal fitting 16 having a side 16A is fixed with a mounting bolt 13, and the above-mentioned embodiment is similarly fixed with a short side 16A.
This is to fix the threshold 3 and the threshold plate 4.

This L-shaped metal fitting 16 also has a short side 16A as in the previous embodiment.
A long hole 16C in the depth direction and a long hole 16D in the vertical direction are provided in the long side 16B, and the sill 3 is fixed adjustable in three directions: left and right, front and back, and up and down.

Figures 12 and 13 show the steel frame 2 or the upper steel frame 15.
A metal fitting 18 having a vertical surface like this is fixed in advance and the sill 3 is similarly fixed via the metal fitting 16'.

As described above, according to the present invention, the sill can be easily supported even in a steel structure building where anchors and mortar cannot be embedded, and the work is easy.Moreover, the sill has metal fittings that can be adjusted in three directions, so It is possible to provide an elevator entrance/exit device that can be installed with high precision in a short time.
