The invention aims to solve the defects in the prior art and provides a safe extension device for cantilever I-shaped steel.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a I-steel safety extension device encorbelments, includes the I-shaped connection external member, the I-shaped connection external member includes two horizontal plates and a vertical board, and the top and the bottom of vertical board respectively fixed mounting in the one side intermediate position that two horizontal plates are close to each other, and two horizontal plates all are linked together with a vertical board, and the both ends of two horizontal plates and a vertical board are the opening setting, one side intermediate position fixed mounting of vertical board has displacement audible-visual annunciator, and displacement audible-visual annunciator's both sides all are equipped with two and set up the location screw on vertical board, install location fastening bolt in the location screw.
Preferably, the horizontal plate and the vertical plate are hollow plates, and the positioning screw holes are communicated with the vertical plate.
Preferably, a plurality of observation holes are formed in one side, far away from the displacement audible and visual alarm, of the vertical plate at equal intervals, and the observation holes are communicated with the interior of the vertical plate.
According to the safe extension device for the overhanging I-shaped steel, the components are light and handy, the installation operation is simple, and the problems of complex extension operation and inconvenience in use are effectively solved.
Drawings
Fig. 1 is a schematic front structural view of an overhanging i-steel safety lengthening device provided by the invention;
fig. 2 is a schematic structural view of the back surface of the overhanging i-steel safety lengthening device provided by the invention.
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 clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention, 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.
In the invention, a plurality of observation holes 4 are arranged on one side of the vertical plate 1-2 far away from the displacement audible and visual alarm 3 at equal intervals, the observation holes 4 are communicated with the inside of the vertical plate 1-2, and the observation holes are used for auxiliary installation.
In the invention, an I-shaped connecting sleeve 1 is sleeved with an 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 an observation hole arranged on the back surface of 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 description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
