Drawings
Fig. 1 is a schematic front structural view of an overhanging i-steel safety extension device provided by the utility model;
fig. 2 is the utility model provides a back structure schematic diagram of I-steel safety extension device encorbelments.
In the figure: 1I-shaped connecting sleeve piece, 2 positioning screw holes, 3 displacement audible and visual alarms, 4 observation holes, 1-1 horizontal plate and 1-2 vertical plates.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a safe overhanging i-steel lengthening device comprises an i-shaped connecting sleeve 1, wherein the i-shaped connecting sleeve 1 has certain rigidity, the i-shaped connecting sleeve 1 comprises two horizontal plates 1-1 and a vertical plate 1-2, the top and the bottom of the vertical plate 1-2 are respectively and fixedly arranged at the middle position of one side of the two horizontal plates 1-1, which are close to each other, the two horizontal plates 1-1 are communicated with the vertical plate 1-2, the two ends of the two horizontal plates 1-1 and the two ends of the vertical plate 1-2 are both provided with openings, a displacement audible and visual alarm 3 is fixedly arranged at the middle position of one side of the vertical plate 1-2, the two sides of the displacement audible and visual alarm 3 are both provided with two positioning screw holes 2 arranged on the vertical plate 1-2, and positioning fastening bolts are arranged in the positioning screw holes 2, the positioning and fastening bolt is used for fastening the I-shaped steel on the two sides.
In the utility model, the horizontal plate 1-1 and the vertical plate 1-2 are hollow plates, and the positioning screw hole 2 is communicated with the vertical plate 1-2.
The utility model discloses in, one side equidistance interval that displacement audible-visual annunciator 3 was kept away from to vertical board 1-2 is equipped with a plurality of observation holes 4, and observes hole 4 and is linked together with vertical board 1-2 is inside, observes the hole and is used for supplementary installation.
In the utility model, the I-shaped connecting sleeve 1 is sleeved with the I-shaped steel to be lengthened, the I-shaped steel to be lengthened penetrates into the other end of the I-shaped connecting sleeve 1, and the I-shaped connecting sleeve 1 is adjusted to a corresponding position through the observation hole arranged on the back surface in the middle of the I-shaped connecting sleeve 1; screwing down positioning fastening bolts on the I-shaped connecting sleeve to fasten the I-shaped steels on two sides;
and starting the displacement audible and visual alarm, wherein the displacement audible and visual alarm takes a gap between the middle I-beams as a detection object and takes a certain relative displacement, such as 10mm, as an alarm value, after the displacement audible and visual alarm is started, the relative displacement of the two side I-beams exceeds the early warning value, namely, the alarm buzzes and flashes, and the displacement audible and visual alarm can reset after hidden danger is removed.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
