Abstract

PURPOSE:To secure the simple constitution and the superior workability and permit the installation free from trouble even if the height of the concrete cut part of a building floor is small, by setting an adjustment part within the thickness dimension of an entrance/exit sill previously forming an elliptical hole for the vertical adjustment and a plurality of anchor bolt holes including spare holes, on a fixed metal fitting. CONSTITUTION:The vertical part 3a' of a supporting metal fitting 3' is fixed with the inner wall 2b of an elevator passage of a building 2 by anchor bolts 6, and other part 3' is tightened on a fixed metal fitting 10 fixed on a concrete cut part 2a by anchor bolts 9, by bolts 11. Since a hole 12 on the fixed metal fitting side of the bolt 11 is an elliptical hole, a sill 1 for an entrance/exit can be easily adjusted vertically. A vertical part 3c' is erected upward for a horizontal part 3b', and since arrangement is carried out so that the erection part is accommodated within the thickness dimension of the sill 1, it is enough for the height dimension 11 of the cut part 2a to be increased slightly larger than the thickness dimension of the sill 1, and the cut part 2a can be reduced to the necessary min. extent. In addition, a plurality of holes 13 for bolts 9 including spare holes are drilled on the fixed metal fitting.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator entrance/exit sill device, and in particular, it combines two metal fittings, has good workability, has a simple structure, and is capable of vertically centering the entrance/exit sill. This invention relates to an elevator entrance/exit threshold device that can be easily installed.

[Conventional technology]

Conventionally, an elevator entrance/exit system has a structure in which one end of the support fitting of the entrance/exit sill is welded to the reinforcing steel of the building.

The reason for welding was to prevent it from slipping, since the structure is such that after adjusting the height using the height adjustment bolt on one side of the support metal fittings, the entire entrance/exit sill device is supported by the bolts, resulting in poor stability against lateral displacement due to earthquakes.

In addition to the prior art, there is also a structure in which a vertical height adjustment bolt is provided under the doorway sill, as disclosed in Japanese Patent Laid-Open No. 61-94987.

[Problem to be solved by the invention]

In the conventional technology, it is necessary to sharpen the reinforcing bars of the building at one location at a time.For example, in the case of a building with four or five floors, there are 12 to 20 locations, which requires a considerable amount of man-hours. It required

Additionally, if there is no reinforcing bar at the desired location, a suitable member is welded between the entrance sill support fitting and the reinforcing bar, but this is not desirable from a quality control perspective as it requires on-site adjustment.

Furthermore, the welding work itself involves the hassle of preparing a welding machine and welding tools, and the structure fixed by welding has problems from the standpoint of fire prevention.

Furthermore, in Japanese Patent Application Laid-Open No. 61-94987, the adjustment mechanism parts such as adjustment bolts are located at the bottom of the doorway sill,
The device itself is taller. For this reason, elevator sills with guide grooves have a certain thickness (usually 20~20 mm).
(approximately 30 m), so if the height of the concrete cutout in the building floor is small, a lot of work will be required, and there is also the disadvantage that it cannot be applied to buildings whose structure does not allow sharpening. .

[Problem to be solved by the invention]

An object of the present invention is to provide an entrance/exit sill device that has a simple structure, good workability, and can be installed without any problem even when the height of a concrete cutout in a building floor is small.

[Means to solve the problem]

The above purpose is to provide an entrance/exit sill system in which the entrance/exit sill support bracket is not welded to the building's reinforcing steel, but instead is bolted to a fixing bracket separately fixed to the building floor and the entrance/exit sill support bracket adjustable in the vertical direction. The structure is such that the adjustment part fits within the thickness of the doorway sill, and the fixing bracket has multiple holes for anchor bolts, including oblong holes for upward and downward adjustment and spare holes. achieved.

[Effect]

One end of the support fitting for the entrance/exit sill is raised upwards, and the structure allows the lowered part to fit within the thickness of the sill, making it possible to keep the entire entrance/exit sill device low, reducing the height of the notch in the building concrete. Entrance/exit thresholds can be installed even if the area is small.

In addition, when installing fixing brackets that are directly fixed to the building floor, multiple holes for anchor bolts, including spare holes, are drilled in the fixing bracket, so in the unlikely event that the anchor bolts are in the original position, the reinforcing bars on the building side If there is any interference with the fixing fitting, it can be easily fixed with an anchor bolt using another hole without moving the fixing fitting itself.

〔Example〕

An embodiment of the present invention will be explained below with reference to FIGS. 1 to 4. First, FIG. 2 shows a plan view of the entrance/exit portion of the elevator. Reference numeral 1 denotes an entrance sill installed in a concrete notch 2a of a building 2, which is supported and fixed by a support fitting 3.

4 is an entrance/exit door, and 5 is an entrance/exit frame.

Next, a conventional doorway sill structure will be explained in detail with reference to FIG. The support fitting 3 for receiving the entrance/exit threshold is composed of a vertical part 3a and a horizontal part 3b.The part 3a is fixed to the inner wall 2b of the hoistway of the building 2 with an anchor bolt 6, and the other part 3b is attached to the reinforcing bar 7 of the building. It is fixed by welding. The upper and lower directions of the entrance/exit sill can be adjusted by setting the height adjustment bolt 8 to a predetermined position before welding.

Next, the doorway sill device of the present invention will be explained with reference to FIGS. 1 and 4.

FIG. 1 is a detailed view corresponding to FIG. 3 showing one embodiment of the present invention, and FIG. 4 is a cross section taken along line BB in FIG. 1.

First, in FIG. 1, the support fitting 3' for receiving the entrance/exit door sill is composed of a vertical part 3a', a horizontal part 3b', and a small vertical part 3c'.
The other part 3c' is fastened by a bolt 1l to a fixture 10 fixed to the concrete notch 2a by a hair anchor bolt 9. Incidentally, since the hole 12 on the side of the fixing metal fitting of the bolt 11 is elongated, the entrance/exit threshold can be easily adjusted in the upward and downward directions.

Here, the small vertical part 3c' is raised upwards with respect to the horizontal part 3b' as shown in the figure, and the raised part is at the entrance/exit threshold 1.
Since the height dimension H of the notch 2a in the building floor only needs to be slightly larger than the thickness dimension of the entrance sill 1, the notch in the building floor can be kept to a minimum. Can be done. Further, as shown in FIG. 4, the fixing fitting has a plurality of holes 13 for anchor bolts 9, including preliminary holes. (In this example, a total of two holes are bored.) Here, the hole 13 is
The holes are respectively shifted by appropriate distances C and D in the Y direction.

The entrance/exit sill of the present invention has the above structure, so even if the height of the concrete notch is small, the height can be easily adjusted without the need for prayer work.Furthermore, since a preliminary hole for the anchor bolt is provided, the anchor bolt and the building can be easily adjusted. Even if reinforcing bars interfere, it can be easily fixed using the spare holes.

〔Effect of the invention〕

According to the present invention, one end of the support fitting of the entrance/exit sill is firmly fixed to the inner wall of the hoistway with an anchor bolt, the other end is raised within the thickness dimension of the entrance/exit sill, and the raised part is fixed to the concrete floor of the building. The structure is such that bolts can be bolted to the fixing bracket with elongated holes for adjusting the height in an adjustable manner upwards and downwards, making it easy to adjust the entrance threshold regardless of changes in the height of the concrete cutout in the building floor. Can be adjusted upward and downward,
Furthermore, since the entire entrance/exit sill device is kept low, even if the depth of the concrete notch is shallow, there is no need for cutting work, and the entrance/exit sill can be easily installed, greatly reducing installation time. This also improved quality by eliminating on-site welding work.
