Description

[Detailed Description of the Invention] This invention relates to an improvement of a weir plate provided on an elevator landing floor.

A conventional example will be explained with reference to FIGS. 1 to 3.

A guide piece 3 is attached to the lower end of a door 2 whose upper part is suspended and which opens and closes an entrance/exit 1, and is guided in a guide groove 5a provided in a threshold 5 of a threshold device 4.

, the second threshold device 4 has a copper base plate 6 fixed to the lower surface of the threshold 5 with bolts 7 arranged at appropriate intervals,
Furthermore, the upper side 8a of the support angle 8 is attached to the base plate 6.
is fixed with bolts 9.

In this state, the sill device 4 aligns the upper surface 5b of the sill 5 with the height of the planned floor surface 10 of the building, and the vertical piece 8 of the support angle 8
b is fixed to the wall 12 of the building with an anchor bolt 11.

Thereafter, the front end 5C of the sill 5 is adjusted to a device consisting of an elevator using an elongated hole (not shown) provided in the upper side 8a of the support angle 8, and the bolt 9 is completely fixed.

In addition, building method 10a is approximately 50 mm-
It has been constructed approximately 200mm lower.

Furthermore, due to construction errors, the wall 12 of the building is constructed approximately 30 mm to 100 mm away from the rear end 5d of the sill 5, so the sill device 4, building assembly method 10a, and wall 1 of the building
A fairly large space B (Fig. 1) is created between the two.

Additionally, this space changes on each floor of the building.

Conventionally, as a method of closing this space B, iron rods 13 are passed between the anchor bolts 19 and the foundation plate 6 installed at appropriate intervals in the construction method 10a of the building, and both ends are welded to each of them.

Further, a suitable weir plate 14 was fixed to the iron rod 15 with a wire 15, and a mortar 16 was poured over it to close the space B.

However, if this is done, it is necessary to change the length of the iron rod 13 and the size of the weir plate 14 for the space B, which has a different size for each floor of the building, and the entrance/exit changes depending on the size of the elevator. In order to cope with the width dimension 1, it is necessary to prepare iron bars 13 and weir plates 14 of different sizes for each site, so it is completely impossible to mass produce them in a factory, so they are made by matching the actual items at the installation site. was the actual situation.

Another disadvantage is that welding the iron rod 13 and fixing the weir plate 14 require a large amount of work time.

This idea uses mass-produced parts with fixed dimensions to easily cope with changes in the size of the space B, which greatly reduces the work time for fixing, and improves the efficiency of installation work. The aim is to improve it drastically.

An embodiment of this invention will be explained with reference to FIGS. 4 to 6.

Reference numeral 17 is a weir plate material, which is a commercially available perforated steel plate of an appropriate thickness with holes drilled at equal intervals and cut to a constant width dimension C and length dimension.

A suitable number of hooks 18 are provided on the base play 1-6 at intervals that are an integral multiple of the inter-hole layers of the weir plate 17.

This hook 18 is hooked into a hole at one end of the weir plate 17, and the other end is fixed with an anchor bolt 19 by bending it appropriately in accordance with the construction method of the building.

Furthermore, any changes in the size of the entrance/exit can be accommodated by adjusting the overlapping dimension E of the weir plates 17 or by increasing or decreasing the number of weir plates 17.

The fixing work is completed by pouring the mortar 16 onto the weir plate material 17 fixed as described above.

According to this invention, the iron rods 13 and the weir plates 14, which are different for each floor and elevator landing size, are no longer required, and the parts can be unified and the cost of parts can be reduced.

Further, since welding work is eliminated and the troublesome work of fixing the weir plate 14 is eliminated, the work time required for fixing is greatly shortened and the workability of installation is improved.

Further, FIG. 7 shows another embodiment.

6a bends the rear end of the base plate upward to form an engaging portion, and also bends one end 17a of the weir plate material 17 to engage with each other.

Furthermore, if the other end 17b of the weir plate material 17 is bent so as to bite into the mortar, the work of installing anchor bolts can be omitted, and the work time for installation can be further reduced.

Note that the perforated steel plate 17 in the above embodiment is designed to have good adhesion with the mortar 16 and to prevent relative displacement even when used for a long time. It is clear that the same effect can be obtained by cutting a member welded with gold steel on one side to the dimensions C and D described above7, and drilling holes at appropriate intervals on the hook 1B side and the anchor bolt 19 side. be.

As mentioned above, this idea is based on the idea that one side of the barrier plate of the elevator landing, which seals off the space created between the threshold device, the landing powder floor, and the wall of the building, is provided on the wall side of the building below the threshold device. It is made up of a predetermined number of weir plates of a certain size that are fixed and fixed to the holding part, the center part is bent toward the space, and the other side is engaged and fixed to the landing powder floor, so it can be used for various sizes of the space. On the other hand, standardized weir plate materials can be used, and the efficiency of installation work can be greatly improved.
