Description
Technical Field
The utility model relates to a wire fixing device that is used for steel box girder foil gage to paste.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
When a load test of a bridge containing the steel box girder is carried out, a strain gauge needs to be adhered to the surface of the steel box girder so as to test the stress condition of the steel box girder. When the strain gauge is adhered to the steel box girder (particularly to the top plate of the steel box girder), in order to prevent the wire from moving and affecting the adhesion and welding of the strain gauge, the wire needs to be fixed on the top plate of the steel box girder before the strain gauge is adhered. A wire is generally fixed by using an adhesive tape to adhere a strain gauge on the surface of concrete, but the surface of a steel box girder is generally coated with a smooth protective coating, so that the adhesiveness is poor. If the lead is pasted by the adhesive tape, the lead can not be pasted, or the lead needs to be pasted by a large amount of adhesive tape, but the lead is easy to loosen.
In addition, after the strain gauge is adhered and welded, in order to prevent the strain gauge from deteriorating or losing effectiveness, the lead wire led out by the strain gauge is not easy to pull. However, the field environment and personnel conditions of the test site are complex, the lead led out by the strain gauge can be inevitably torn, and if the lead near the strain gauge is not well fixed, the accuracy of the test of the strain gauge can be possibly affected.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art, an object of the utility model is to provide a wire fixing device that is used for steel box girder foil gage to paste. The device can effectively solve the problems that the lead is not easy to fix, the material consumption is more wasted when the lead is pasted and welded on the strain gauge, the consumed time is long, and the test accuracy of the strain gauge is influenced due to the drawing of the lead.
In order to solve the technical problem, the technical scheme of the utility model is that:
the utility model provides a wire fixing device for steel case roof beam foil gage is pasted, include, stride the line frame, the line ball piece, two magnet bases, the wire, the line ball piece is located the well lower part of striding the line frame, the bottom plane of line ball piece coincides with the bottom plane of striding the line frame, the line ball piece strides the wire setting with striding the line frame in the direction of perpendicular to wire, stride line frame and line ball piece fixed connection, two magnet bases are located the both ends of striding the line frame respectively, the symmetry sets up, two magnet bases are located the both sides of wire respectively, the wire passes from the intermediate position of line ball piece bottom, the line ball piece sticiss the wire.
The utility model discloses a wire fixing device has solved the wire that appears when steel case roof beam pastes the foil gage difficult fixed, paste the consumptive material extravagant more, consume the time long, the wire draws the problem that influences foil gage test accuracy of dragging.
As a further technical scheme, the material of the line pressing block is a high-resilience rubber material. When the wire pressing block generates compression deformation due to the existence of the wire, the wire pressing block can provide higher elastic force for the wire, so that the wire is tightly attached to the top plate of the steel box girder.
The utility model has the advantages that:
the utility model relates to a wire fixing device for steel box girder foil gage is pasted, the principle is simple, the structure is light and handy, with low costs, can use repeatedly, and it is comparatively convenient to use, even more smooth steel box girder top surface still can play better fixed action, compares in current formula fixed method of pasting, can alleviate operating personnel's operating time, and utilization that can relapse can not receive the influence of experimentation.

Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As shown in the figures 1, 2 and 3, the lead 2 is connected with the pressure transformer 1, the lead 2 vertically penetrates through the line pressing block 6 and the line crossing frame 4, the line pressing block 6 and the line crossing frame 4 are matched to fix the lead 2, so that the lead 2 cannot move in the direction perpendicular to the lead 2, and meanwhile, the lead 2 cannot move basically in the direction parallel to the lead 2 because the line pressing block 6 tightly presses the lead 2. The method is used, after the pressing variable sheet 1 and the lead 2 are placed,
on steel box girder roof 5, stride the wire setting from the direction of perpendicular to wire with line ball 6, can guarantee the position stability of wire 2. The magnet bases 3 are positioned at two ends of the wire spanning frame 4, and a larger attraction force is formed between the magnet bases and the 3 steel box girders, so that the stability of the wire spanning frame 4 is improved, and more importantly, the stability of the wire spanning frame relative to the steel box girders can be improved.
The magnet base 3 and the wire-crossing frame 4 and the wire pressing block 6 can be bonded and fixed, the wire-crossing frame 4 is made of plastic, and the wire pressing block 6 is made of high-resilience rubber material.
As shown in figure 2, the material of the wire pressing block 6 is high-resilience rubber material, and when the wire pressing block 6 generates compression deformation due to the existence of the wire 2, the wire pressing block 6 can provide high elastic force for the wire 2, so that the wire 2 is tightly attached to the steel box girder top plate 5. And the larger adsorption force between the magnet base 3 and the steel box girder top plate 5 ensures that the whole device can firmly fix the lead 2 on the steel box girder top plate 5.
As shown in fig. 2, since the wire pressing block 6 is made of a highly elastic material, when the wire is pressed, a depression is formed at the bottom of the wire pressing block to be tightly pressed against the wire.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
